Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims priority under 35 U.S.C. § 119 to Korean Application Nos. 10-2023-0084423 filed on Jun. 2, 2023, and 10-2024-0013454 filed on Jan. 29, 2024, whose entire disclosures are hereby incorporated by reference.

BACKGROUND

1. Field

The present disclosure relates to a water supply device and a faucet.

2. Background

A water supply device is a device for supplying water to a user. When a user operates the water supply device, water stored in the water supply device or raw water supplied from outside may be supplied to the user through the water supply device. An example of the water supply device is a faucet used in a bathroom or kitchen.

The faucet may supply cold water and hot water from externally supplied raw water to a user. The faucet may provide a user with either cold water or hot water, or a mixture of cold water and hot water. Recently, a device such as a filter or a thermostat has been mounted inside the faucet.

Accordingly, a plurality of flow paths may be provided inside the faucet to mix the raw water or allow the raw water to pass through a device such as the filter or the thermostat. The plurality of flow paths may be implemented as a plurality of hoses. However, the plurality of hoses complicates the structure of the faucet and increases the number of parts, thereby reducing manufacturing convenience. In addition, each of the hoses has a small flow path cross-sectional area compared to an overall volume, which is disadvantageous in securing a large flow rate and causes the problem of the flow path being blocked when the hose is excessively bent.

As another example, a faucet may be made of a casting. For example, a faucet may be molded of a casting made of brass. Accordingly, the faucet made of a casting is high in manufacturing cost, and due to the nature of a material thereof, post-processing thereof is not easy, so there is a problem with a high defect rate during a manufacturing process. In addition, a faucet made of a casting is heavy, so when the faucet is installed on a wall surface, the faucet has a problem of reduced stability due to a large weight thereof.

To solve this problem, a faucet may be made of a resin material. Korean Utility Model Registration No. 20-0491186 (Prior Art 1) discloses a technology to create a faucet by thermally fusing two parts made of ABS resin. U.S. Pat. No. 9,403,304 B2 (Prior Art 2) discloses a technology in which resin parts constituting a coupler of a faucet are thermally fused and coupled to each other.

However, in Prior Art 1 and Prior Art 2, flow paths are formed integrally inside the main body of a faucet, and thus it is difficult to implement complex flow paths, and when the flow paths are damaged, the entire faucet is required to be replaced. In addition, in Prior Art 1 and Prior Art 2, when adding other parts (a filter or a thermostat, etc.) to the inside of a faucet body, flow paths to transfer water to the other parts are also required to be implemented in the faucet body, so the overall volume of the faucet is required to be very large.

Korean Patent Application Publication No. 10-2018-0015930 (Prior Art 3) discloses a dishwasher having a water jacket provided inside. The water jacket includes two parts joined by heat fusion, and has a storage part inside to store washing water. However, in Prior Art 3, the storage part is required to be included, thereby causing a large volume, and the function of mixing cold and hot water like a typical faucet is not provided, thereby making application to the faucet difficult.

Meanwhile, in order to simplify the structure of the faucet body, the filter may be installed in a replaceable form on a shower head connected to the faucet. However, when the faucet is provided with multiple water outlets, the number of filters is also required to be increased. For example, when a plurality of water outlets, such as a handheld showerhead, a rainfall water outlet, and a bathtub water outlet, are connected to the faucet, filters are required to be placed at the water outlets, respectively, so there is a problem in that the number of filters increases.

Additionally, the filter provided in the shower head, etc. is exposed to the outside and spoils the aesthetics. In addition, each of the outlets, such as shower heads has limitation in a size, and thus the filter is required to be miniaturized, and the replacement cycle of the filter is decreased.

In addition, recently, a technology to supply power to a display by mounting a water-flow generator inside the faucet has been developed. Korean Patent No. 10-2147222 (Prior Art 4) and Korean Patent Application Publication No. 10-2022-0140919 (Prior Art 5) disclose a technology to measure water quality or emit LEDs by mounting a generator inside a shower. In Prior Art 4 and Prior Art 5, since the generator is arranged on the showerhead side rather than in a faucet body, a function to utilize generated power is limited, and it is difficult to transmit the generated power to the faucet body. The generator may be installed in the faucet body, but in this case, the flow path structure of the faucet body may be more complicated.

In addition, when impurities contained in water supplied to the water-flow generator adhere to the inside of the water-flow generator, the water-flow generator may be damaged.

DETAILED DESCRIPTION

Below, some embodiments of the present disclosure are described in detail through illustrative drawings. When adding reference numerals to components in each drawing, it should be noted that identical components are given the same reference numerals as much as possible even if they are shown in different drawings. Additionally, when explaining an example of the present disclosure, if a detailed description of the related known structure or function is determined to impede understanding of the embodiments of the present disclosure, the detailed description thereof is omitted.

The present disclosure relates to a water supply device 10. The water supply device 10 of the present disclosure may provide raw water supplied from an external water source by treating the raw water in various ways. The water supply device 10 may be applied to a faucet or other water supply devices. Here, the faucet may include a faucet used in a bathroom, such as a faucet for a shower, and a faucet used in a kitchen, such as a faucet for a sink. Additionally, the faucet may be used as an outdoor faucet in addition to as an indoor faucet. The water supply device 10 may also be applied to a home appliance that supplies water, such as a water purifier.

Here, raw water, which is water supplied from the outside, may be tap water. More specifically, the raw water may include cold water and hot water. For reference, hereinafter, raw water refers to water introduced from the outside, mixed water refers to the mixed water of the cold water and the hot water, controlled water refers to water whose flow rate is controlled by a flow rate controller 150, and purified water refers to water from which impurities have been filtered out by a filter 160.

The water supply device 10 of the present disclosure may provide functions such as mixing of cold water and hot water, purification of water, power supply through a generator 170, information transmission through a display 70, data reception/sending through a communication means, automatic control through a control device, or water discharge through a plurality of water outlets. Hereinafter, description will focus on the structure of the flow path guide pack 100 disposed inside the water supply device 10.

For reference, below, the front-to-rear direction of the water supply device 10 indicates the X-axis direction of FIG. 1. The left-to-right direction of the water supply device 10 indicates the Y-axis direction of FIG. 1. The upper side and lower side direction of the water supply device 10 indicates the Z-axis direction of FIG. 1. In addition, the front side of the water supply device 10 refers to a side in front of the water supply device 10, which is far from an installation surface W, and is marked with Os in FIG. 1. The rear side of the water supply device 10 refers to a side thereof directed to the installation surface W, and is marked with Is in FIG. 1.

Referring to FIG. 1, the water supply device 10 is illustrated to be used as a faucet for shower. A shower may include a first water discharge pipe 1, and a rainfall shower head 2 connected to the first water discharge pipe 1. The shower may include a handheld shower head 4 connected to a second water discharge pipe 3. The second water discharge pipe 3 may be made of a flexible hose material.

The rainfall shower head 2 and the handheld shower head 4 may receive water from the water supply device 10. The water supply device 10 may receive raw water from the outside and transmit the raw water to the rainfall shower head 2 and the handheld shower head 4. Although not shown in FIG. 1, the water supply device 10 may include a lower water outlet 25 (see FIG. 3) for discharging water into a bathtub. Hereinafter, the rainfall shower head 2 will be referred to as a first water discharge part, the handheld shower head 4 will be referred to as a second water discharge part, and the lower water outlet 25 will be referred to as a third water discharge part.

Accordingly, in this embodiment, the water supply device 10 may include a plurality of water discharge parts. Here, the water discharge parts may include the rainfall shower head 2, the handheld shower head 4, and the lower water outlet 25. The water supply device 10 may branch water inside and may transmit the water to any one of the plurality of water discharge parts or to the plurality of water discharge parts.

FIG. 1 illustrates a first knob 40 of a thermostat 140 to control the temperature of water. When the first knob 40 rotates, the thermostat 140 may operate and mixed water including hot and cold water may be discharged, or hot water or cold water may be discharged without mixing with each other. The water supply device 10 may further include a second knob 50 separately from the first knob 40. The second knob 50 is used to operate the flow rate controller 150 for controlling the flow rate of discharged water. When the second knob 50 is rotated, a discharged flow rate may be controlled.

In addition to the first knob 40 and the second knob 50, the water supply device 10 may include selection levers 190. The selection levers 190 may be connected to a water discharge selector 180 to be described below. The water discharge selector 180 allows a user to select which water discharge part among the plurality of water discharge parts to discharge water. In this embodiment, the water discharge selector 180 may include a total of three selection levers 190. The three selection levers 190 may allow water to be discharged to the rainfall shower head 2, the handheld shower head 4, and the lower water outlet 25, respectively.

The selection levers 190 may be placed between the thermostat 140 and the flow rate controller 150. The thermostat 140 and the flow rate controller 150 may be respectively arranged on opposite front ends of the water supply device 10. The selection levers 190 may be arranged between the thermostat 140 and the flow rate controller 150. In this case, the water supply device 10 may provide a user with a unified aesthetics through a symmetrical structure thereof. The thermostat 140, the flow rate controller 150, and the water discharge selector 180 will be described in detail below.

Referring to FIG. 2, the water supply device 10 is shown to be installed on a wall surface, which is the installation surface W. In this way, the rear surface of the water supply device 10 may face the installation surface W, and the water supply device 10 may protrude from the installation surface W. The water supply device 10 may be fixed to the installation surface W through installation adapters 7a and 7b for wall mount. Accordingly, a large load due to the weight of the water supply device 10 may be concentrated on the installation adapters 7a and 7b. In this embodiment, as will be described below, the load applied to the installation adapters 7a and 7b may be reduced through the structure of the flow path guide pack 100, the arrangement of parts thereof, and a reinforcing plate 130 thereof. For another example, the water supply device 10 may be stored in a storage part recessed in a wall surface. For still another example, the lower part of the water supply device 10 may be supported by the installation adapters 7a and 7b connected to the lower part of the water supply device 10.

As illustrated in FIGS. 2 and 3, on the lower portion of the water supply device 10, outlets OH1, OH2, and OH3 and a handle 165′ of the filter 160, which will be described later, may be exposed. A user may hold the handle 165′ and separate and replace a filter part 163, which constitutes the filter 160. In this embodiment, the filter part 163 may be mounted/detached in a vertical direction, and this structure will be described again below.

Referring to FIG. 3 showing the lower side of the water supply device 10, the plurality of outlets OH1, OH2, and OH3 may be open on the lower side of the water supply device 10. The plurality of outlets OH1, OH2, and OH3 may include a first outlet OH1, a second outlet OH2, and a third outlet OH3. Separate hoses may be connected to the first outlet OH1 and the second outlet OH2. In this embodiment, the first outlet OH1 and the second outlet OH2 are arranged adjacent to each other, but in another example, the first outlet OH1 and the second outlet OH2 may be spaced apart from each other.

The first outlet OH1 and the second outlet OH2 may be disposed at a position close to the rear of the water supply device 10. On the basis of FIG. 3, the first outlet OH1 and the second outlet OH2 may be disposed on the lower side of the water supply device 10. That is, the first outlet OH1 and the second outlet OH2 may be disposed close to the installation surface W. In this case, when hoses are connected to the first outlet OH1 and the second outlet OH2, torque applied to the installation adapters 7a and 7b may be reduced due to the weight of the hoses.

In this embodiment, the first outlet OH1 and the second outlet OH2 may be open in a second direction different from a first direction, which is a direction in which a first flow path body 110 and a second flow path body 120 are coupled to each other. The first direction is the same as the X-axis direction of FIG. 1, and the second direction is a direction orthogonal to the first direction (the Z-axis direction of FIG. 1) or may be a direction extending obliquely from the direction orthogonal to the first direction.

The third outlet OH3 may not be connected to a separate hose but may be open downward. Water discharged through the third outlet OH3 may be discharged toward the floor. When a bathtub is placed under the third outlet OH3, the third outlet OH3 may be the lower water outlet 25, and when a sink bowl is placed under the third outlet OH3, the third outlet OH3 may be a sink bowl outlet.

The handle 165′ of the filter 160 described above on the lower part of the water supply device 10 may be exposed. The handle 165′ may protrude from a filter cover 165. A user may rotate the handle 165′ to separate the filter part 163 including the filter cover 165 from the water supply device 10 or mount the filter part 163 to the water supply device 10.

Reference numeral 75 denotes a manipulation button 75. The manipulation button 75 may be used to manipulate the control device (not shown) disposed inside the water supply device 10. For example, the manipulation button 75 may be a reset switch. For another example, the manipulation button 75 may be a power switch to turn on/off the display 70.

FIG. 4 illustrates disassembled parts constituting the water supply device 10. As is illustrated, the exterior and frame of the water supply device 10 may be formed by a casing 20. The casing 20 may be provided with an installation space 23 inside. The front of the installation space 23 is open, and the open portion 21 of casing 20 may be covered by a cover plate 30. In this embodiment, the casing 20 may be formed to be longer in a left and right width than in height. The upper and lower surfaces of the casing 20 may have planar structures parallel to each other. The left and right surfaces of the casing 20 may be curved surfaces. This form of the casing 20 is just one example, and the casing 20 may have various forms. The casing 20 may be regarded as a faucet body.

A rear surface cover 22 may be provided on the rear surface of the casing 20. The rear surface cover 22 may shield the rear of the installation space 23. The rear surface cover 22 may have a structure that protrudes rearward from the casing 20. The rear surface cover 22 may be integrally provided on the rear of the casing 20. The rear surface cover 22 may include an inflow guide 22a for connection to the inlets IH. The inflow guide 22a may be configured as one pair of inflow guides for the inflow of hot water and cold water. Reference numeral 22b indicates a hose passage hole through which a hose passes when the hose is extended.

The lower water outlet 25 may be provided on a lower portion of the installation space 23. The lower water outlet 25 may be connected to the third outlet OH3. Water discharged through the third outlet OH3 may fall downward through the lower water outlet 25. The lower water outlet 25 may be in the form of a long hole in the left-to-right direction.

A filter hole 26 may be open in a lower portion of the installation space 23. The filter hole 26 may be made through the lower surface of the casing 20. The filter hole 26 may be considered as a hole through which the filter part 163 to be described below enters and exits. The filter hole 26 may be made circular in a lower right portion of the installation space 23. The shape of the filter hole 26 may be of various shapes corresponding to the shape of the filter part 163. Reference numeral 27 denotes a hole through which the operation button 75 protrudes.

As illustrated in FIG. 4, the display 70, the flow path guide pack 100, the thermostat 140, the flow rate controller 150, the filter 160, the generator 170, and the water discharge selector 180 may be arranged inside the installation space 23. Among the display 70, the flow path guide pack 100, the thermostat 140, the flow rate controller 150, the filter 160, the generator 170 and the water discharge selector 180, the display 70, the flow path guide pack 100, and the generator 170 may not be exposed to the outside but be stored in the installation space 23. Parts of the thermostat 140, the flow rate controller 150, the filter 160, and the water discharge selector 180 may be exposed to the outside to be manipulated or replaced.

The display 70 may provide various information to a user by using power generated by the generator 170. The display 70 may include the control device. The display 70 may display information such as the temperature and flow rate of the water being discharged, the period of use of the filter part 163, the replacement time of the filter 160, and a currently selected water discharge part. The cover plate 30 may be disposed in front of the display 70, but the cover plate 30 may transmit light emitted of the display 70 forward. To this end, all or part of the cover plate 30 may be made of a transparent or translucent material. When the display 70 is configured as a touch panel, a user may input an operation command by touching the surface of the cover plate 30.

Although not shown, the control device may include a communication module for communication. The communication module may include one or more of a Bluetooth communication module, a WiFi communication module, a Zigbee communication module, and an NFC communication module. The communication modules may receive power through the generator 170.

The thermostat 140, the flow rate controller 150, the filter 160, the generator 170, and the water discharge selector 180 may each be connected to the flow path guide pack 100. Here, the connection may mean that water can pass between two parts. In this embodiment, except for the generator 170 and the water discharge selector 180, each component is not directly connected to each other, but may be indirectly connected through the flow path guide pack 100. Accordingly, the flow path guide pack 100 may provide flow paths for the flow of water. The flow path guide pack 100 may provide flow paths of sufficiently wide and predetermined sizes inside. This structure will be explained in detail again below. This structure will be described in detail again below.

FIGS. 5 and 6 illustrate the exploded states of components arranged in the installation space 23. FIG. 5 illustrates components viewed from a side in front of the water supply device 10, and FIG. 6 illustrates the components viewed from a side behind the water supply device 10. As illustrated in the drawings, the flow path guide pack 100 and the reinforcing plate 130 may be placed at a rearmost position. The thermostat 140, the flow rate controller 150, the filter 160, the generator 170, and the water discharge selector 180 may be arranged on the front of the flow path guide pack 100.

In this embodiment, the thermostat 140, the flow rate controller 150, the filter 160, the generator 170, and the water discharge selector 180 may be arranged left and right or up and down. More precisely, the generator 170 and the water discharge selector 180 may be arranged in a vertical direction at different heights. The thermostat 140 and the flow rate controller 150 may be arranged to be spaced apart from each other in the left-to-right direction. The filter 160, the generator 170, and the water discharge selector 180 may be disposed between the thermostat 140 and the flow rate controller 150. In this way, when the parts except for the flow path guide pack 100 are not arranged in the front-to-rear direction, but are arranged left and right or up and down, the front-to-rear length of the water supply device 10 may be minimized. As described above, when the front-to-rear length of the water supply device 10 is short, torque applied to the installation adapters 7a and 7b may be reduced.

The flow path guide pack 100 may be provided with a plurality of flow paths P inside. The plurality of flow paths P may transmit water to or receive water from the thermostat 140, the flow rate controller 150, the filter 160, the generator 170, and the water discharge selector 180. The flow path guide pack 100 may be considered as being dedicated to the flow paths of water. Of course, water may flow inside the thermostat 140, the flow rate controller 150, the filter 160, the generator 170, and the water discharge selector 180, but the role of transmitting water between the parts may be performed by the flow path guide pack 100.

Inside the installation space 23, the flow path guide pack 100 may be disposed at a position that is biased toward the rear surface cover 22 rather than the cover plate 30. The flow path guide pack 100 may be arranged at a position farther from the cover plate 30 than the thermostat 140, the flow rate controller 150, the filter 160, the generator 170, and the water discharge selector 180. The flow path guide pack 100 may have a larger area than other parts, and be heavy due to the addition of the weight of water flowing through the flow paths P inside. When the flow path guide pack 100 is arranged close to the installation surface W, torque applied to the installation adapters 7a and 7b by the weight of the flow path guide pack 100 may be reduced.

In this embodiment, the flow path guide pack 100 may be disposed closer to the installation surface W than the thermostat 140, the flow rate controller 150, the filter 160, the generator 170, and the water discharge selector 180. The installation adapters 7a and 7b, which transmit external water, may be installed on the installation surface W. When the flow path guide pack 100 is arranged close to the installation surface W, a path through which external water flows into the flow path guide pack 100 may be short.

The flow path guide pack 100 may be erected at the rear of the installation space 23. Here, the being erected means that the opposite ends of the flow path guide pack 100 having a width greater than the thickness of the flow path guide pack 100 based on the coupling direction of the first flow path body 110 and the second flow path body 120 constituting the flow path guide pack 100 are arranged in a vertical direction. In other words, it may be considered that opposite ends having longest sections among edges of a coupling surfaces on which the first flow path body 110 and the second flow path body 120 are coupled to each other are arranged in the vertical direction.

In another embodiment, the flow path guide pack 100 may be arranged in the upper or lower portion of the installation space 23. That is, the flow path guide pack 100 may be arranged in a horizontal direction in the upper portion of the installation space 23, or may be arranged in the horizontal direction in the lower portion of the installation space 23.

Referring to FIG. 7, the flow path guide pack 100 may be erected at the rearmost position. Each of the thermostat 140, the flow rate controller 150, the filter 160, the generator 170, and the water discharge selector 180 may be arranged in whole or in part to overlap the front surface of the flow path guide pack 100 in the front-to-rear direction. Accordingly, the thermostat 140, the flow rate controller 150, the filter 160, the generator 170, and the water discharge selector 180 may be connected to the flow path guide pack 100 in portions overlapping the flow path guide pack 100.

Referring to FIGS. 8 and 9, the flow path guide pack 100 may be arranged in a first area T1 of the installation space 23. The thermostat 140, the flow rate controller 150, the filter 160, the generator 170, and the water discharge selector 180 may be arranged in a second area T2 of the installation space 23. The first area T1 and the second area T2 are formed by arbitrarily dividing the installation space 23. Here, the second area T2 may be located closer to the front surface of the casing 20 than the first area T1. Conversely, the first area T1 may be provided closer to the installation surface W than the second area T2. The flow path guide pack 100 may be arranged in the first area T1 without going into the second area T2. Through this, the installation space 23 may be utilized efficiently.

Referring to FIGS. 5 and 6, the flow path guide pack 100 may include the first flow path body 110 and the second flow path body 120. The first flow path body 110 and the second flow path body 120 may have shapes that correspond to each other. When the first flow path body 110 and the second flow path body 120 are combined with each other, the first flow path body 110 and the second flow path body 120 may have the same areas so that any one of the first flow path body 110 and the second flow path body 120 does not protrude further outside the perimeter thereof. When the first flow path body 110 and the second flow path body 120 are combined with each other, the plurality of flow paths P may be formed therebetween.

Referring to FIG. 5, in the first flow path body 110, first paths P1 may be provided in recessed forms. Referring to FIG. 6, in the second flow path body 120, second paths P2 may be provided in recessed forms. Each of the first paths P1 and each of the second paths P2 may have shapes and positions corresponding to each other. Referring to FIG. 12, the first paths P1 and the second paths P2 may make the flow paths P which are continuous in the front-to-rear direction.

The flow paths P may form paths independent of the installation space 23. Since the flow paths P are provided inside the flow path guide pack 100, the flow paths P may be separated from the installation space 23 to form independent paths.

The plurality of flow paths P may be composed of individual flow paths P1 to P5 that are independent of each other. The individual flow paths P1 to P5 may (i) transmit water introduced through the inlet IH to each of parts, (ii) connect the parts to each other, and (iii) discharge water passing through the parts through an outlet OH. The individual flow paths P may have independent paths. Here, independence may mean that each of the individual flow paths P1 to P5 has a separated path without being connected to each other.

The first flow path body 110 and the second flow path body 120 may be respectively provided with a first close contact part FA1 and a second close contact part FA2 corresponding to each other. The first close contact part FA1 may protrude from the surface of the first flow path body 110 in a direction toward the second flow path body 120. Conversely, the second close contact part FA2 may protrude from the surface of the second flow path body 120 in a direction toward the first flow path body 110. The first close contact part FA1 and the second close contact part FA2 may be in close contact with each other to form the flow paths P. When the first close contact part FA1 and the second close contact part FA2 are in close contact with each other, the first close contact part FA1 and the second close contact part FA2 may be a kind of walls continuous in front-to-rear directions, and the flow paths P may be formed between the walls.

In a portion in which the first flow path body 110 and the second flow path body 120 face each other, the flow paths P may be formed in the remaining portion except for portions on which the first close contact part FA1 and the second close contact part FA2 are in close contact with each other. That is, since the first close contact part FA1 and the second close contact part FA2 are a kind of walls continuous in the front-to-rear directions, the flow paths P, which are empty spaces, may be formed in the remaining portions except for a portion on which the first close contact part FA1 and the second close contact part FA2 are in close contact with each other.

The first close contact part FA1 and the second close contact part FA2 may be fused to each other. Here, “fusion” means “being fixed to each other” in close contact with each other. The first close contact part FA1 and the second close contact part FA2 may be fused to each other by using vibration fusion, heat fusion, or ultrasonic fusion. The heat fusion may be implemented in a method in which after heating, softening, and melting the first flow path body 110 and the second flow path body 120 fixed to two jigs by pressing the first flow path body 110 and the second flow path body 120 with a hot plate heated to a temperature slightly higher than the melting temperature of the material of the first flow path body 110 and the second flow path body 120, when fusing areas are sufficiently melted, the hot plate is removed, the first flow path body 110 and the second flow path body 120 are pressed to each other, and then are cooled until hardens to fuse the first flow path body 110 and the second flow path body 120.

For another example, the first close contact part FA1 and the second close contact part FA2 may be coupled to each other by bonding. For still another example, the first flow path body 110 and the second flow path body 120 may be coupled to each other by using separate fasteners such as screws. In this case, the first close contact part FA1 and the second close contact part FA2 may be sealed by using a rubber sealing member.

Prior to describing the detailed structure of the flow paths P, to describe the reinforcing plate 130, the reinforcing plate 130 may reinforce the strength of the flow path guide pack 100. The flow path guide pack 100 may be connected to the installation adapters 7a and 7b, so that torque due to the weight of the water supply device 10 along with the installation adapters 7a and 7b may be concentrated on the flow path guide pack 100. Accordingly, the flow path guide pack 100 may be damaged or removed from an installation position thereof. The reinforcing plate 130 may prevent the damage or removal of the flow path guide pack 100.

Specifically, the reinforcing plate 130 may have a flat plate structure. The reinforcing plate 130 may be made of a high-strength metal material. The reinforcing plate 130 may be in surface contact with the surface of the flow path guide pack 100. The reinforcing plate 130 may be coupled to the first flow path body 110 in surface contact with the surface of the first flow path body 110 of the flow path guide pack 100. The installation adapters 7a and 7b may be coupled to the reinforcing plate 130. Accordingly, the installation adapters 7a and 7b may not be directly coupled to the flow path guide pack 100, but may be indirectly coupled thereto through the reinforcing plate 130.

Referring to FIGS. 10 and 11, in the reinforcing plate 130, one pair of plate holes 131a and 131b may be open. Among the one pair of plate holes 131a and 131b, a first plate hole 131a may be a part through which cold water is introduced. Among the one pair of plate holes 131a and 131b, a second plate hole 131b may be a part through which hot water is introduced. The first plate hole 131a may be connected to a first adapter 7a among the installation adapters 7a and 7b, and the second plate hole 131b may be connected to a second adapter 7b among the installation adapters 7a and 7b.

Flange fastening holes 132 may be provided around the plate hole 131a or 131b. The flange fastening holes 132 are fastening holes for the coupling of the flange 136. After fasteners (not shown) pass through the flange fastening holes 132 and are fastened to fastening grooves 139 of the flange 136, the flange 136 may be fixed to the reinforcing plate 130. The flange 136 is intended to be assembled with the installation adapters 7a and 7b, and a flange thread 138 may be provided on the surface of the flange 136.

Service holes 133 may be open in the reinforcing plate 130. The service holes 133 are intended for maintenance of the water supply device 10. The service holes 133 may be connected to through holes 119a of the first flow path body 110. When a service stopper B1 is fastened to each of the through holes 119a of the first flow path body 110 after the service stopper B1 passes through each of the service holes 133, the service hole 133 and the through hole 119a may be maintained to be normally blocked. When the service stopper B1 is removed and washing water or high temperature steam is injected into the flow path guide pack 100 through the service hole 133, the flow paths P and each component inside the flow path guide pack 100 may be washed.

Body fastening holes 135 may be open in the reinforcing plate 130. The body fastening holes 135 are intended to combine the reinforcing plate 130 and the first flow path body 110 with each other. A fastener (not shown) passing through each of the body fastening holes 135 may be assembled to the fixing hole 119b of the first flow path body 110. Accordingly, the reinforcing plate 130 may be coupled to the first flow path body 110. The body fastening holes 135 may be arranged on the edge of the reinforcing plate 130.

In this embodiment, while the reinforcing plate 130 is coupled to the flow path guide pack 100, the reinforcing plate 130, together with the flow path guide pack 100, may be stored in the installation space 23. In this case, the flange 136 of the reinforcing plate 130 may be exposed rearward through the inflow guide 22a of the rear surface cover 22. The nut parts 8a and 8b of the installation adapters 7a and 7b may be assembled on the flange 136. In this case, raw water may be supplied into the flow path guide pack 100 through adapter inlets 7a′ and 7b′ of the installation adapters 7a and 7b.

For reference, the adapter inlets 7a′ and 7b′ of the installation adapters 7a and 7b may be connected to a raw water supply pipe (not shown) fixed to the installation surface W. Briefly looking at the installation adapters 7a and 7b with reference to FIG. 11, the installation adapters 7a and 7b may be configured as one pair of installation adapters. Cold water may be supplied through the first adapter 7a of the installation adapters 7a and 7b. Hot water may be supplied through the second adapter 7b of the installation adapters 7a and 7b. In the first adapter 7a, a first adapter inlet 7a′ may be open, and in the second adapter 7b, a second adapter inlet 7b′ may be open.

Reference numeral 8a is a first nut part 8a provided in the first adapter 7a, and reference numeral 8b is a second nut part provided in the second adapter 7b. In this embodiment, the first adapter inlet 7a′ and the first nut part 8a may have a structure eccentric to each other rather than being coaxial with each other. Even if there is an error in a gap between one pair of raw water supply pipes mounted in the installation surface W, the eccentric structure may allow the error to be compensated. Reference numerals 8a′ and 8b′ indicate adapter holes connected to the adapter inlets 7a′ and 7b′, respectively. Each of the adapter holes 8a′ and 8b′ may be connected to a flange hole 137 formed through the flange 136.

Referring to FIG. 10, when looking at the first flow path body 110 constituting the flow path guide pack 100, the inlets IH may be provided in the first flow path body 110. The inlet IH may be a part for supplying external raw water into the flow paths P. Cold and hot water may be supplied through the inlet IH. In this embodiment, the inlet IH may include a first inlet IH for cold water inflow and a second inlet IH for hot water inflow. As another example, only one inlet IH may be provided in the first flow path body 110.

The inlet IH may be open in the front-to-rear direction in the first flow path body 110. More specifically, the first flow path body 110 and the second flow path body 120 may be coupled to each other in the first direction (the front-to-rear direction), and the inlet IH may also be open in the first direction. In this case, the inlet IH may be provided by penetrating a wide portion of the first flow path body 110, and the diameter of the inlet IH may be increased. When the diameter of the inlet IH increases, external raw water may be introduced efficiently through the inlet IH. When the diameter of the inlet IH is small, water pressure in the inlet IH may increase, and cracks and water leaks may occur in a fused portion between the first flow path body 110 and the second flow path body 120. In this embodiment, the inlet IH may also be open in the first direction to reduce the water pressure.

The first flow path body 110 may include an outlet OH. The outlet OH may be a part through which water passing through the flow path guide pack 100 is discharged to the outside. Here, the outside refers to space to which water is discharged through the outlet. A separate hose may be coupled to the outlet OH, allowing water to be discharged at a distant location.

In this embodiment, the outlet OH may include the first outlet OH1, the second outlet OH2, and the third outlet OH3. The first outlet OH1 and the second outlet OH2 may be arranged to be adjacent to each other, but in another example, the first outlet OH1 and the second outlet OH2 may be spaced apart from each other.

As illustrated in FIG. 10, the first outlet OH1 and the second outlet OH2 may be disposed in the first flow path body 110. On the other hand, the third outlet OH3 may be arranged not in the first flow path body 110 but in the water discharge selector 180. Referring to FIG. 29, a movement guide 191 constituting the water discharge selector 180 may include a guide water discharge pipe 192 whose first end part is inserted into the flow path guide pack 100, and the third outlet OH3 may be provided on an end of the guide water discharge pipe 192. For another example, the guide water discharge pipe 192 of the movement guide 191 may be omitted, and the third outlet OH3 may be provided in the flow path guide pack 100.

Referring to FIG. 11, the first flow path body 110 may be provided with the through hole 119a. The service stopper B1 may be coupled to the through hole 119a. Each of fixing holes 119b to which the fastener is fastened may be disposed on the edge of the first flow path body 110. Reference numeral 119c denotes an additional fixing hole corresponding to the additional fastening hole of the reinforcing plate 130. A separate fastener (not shown) may be fastened to the additional fixing hole 119c, so that a fastening force between the reinforcing plate 130 and the first flow path body 110 may be increased.

Referring to FIG. 12, the first flow path body 110 may include a plurality of flow paths P. The plurality of flow paths P may each perform different functions. The plurality of flow paths P may extend in left-to-right directions. The plurality of flow paths P may extend in inclined directions in some sections. The specific function of each of the flow paths P will be described again below.

The plurality of flow paths P may be arranged on the same plane inside the flow path guide pack 100. In FIG. 13, reference numeral SP indicates a plane crossing the inside of the flow path guide pack 100. Here, the same plane refers to a virtual plane and may refer to a plane made by a Y-axis and a Z-axis in FIG. 1.

Referring to FIG. 13, among the plurality of flow paths P, a first inflow path P1a connecting the first inlet IH with the thermostat 140, and a second inflow path P1b connecting the second inlet IH with the thermostat 140 are illustrated. In addition, in FIG. 13, a third outflow path P5c connecting the filter 160 with the third outlet OH3 is illustrated. The first inflow path Pa, the second inflow path P1b, and the third outflow path P5c may be provided on the same plane. Although not shown in FIG. 13, a mixed water flow path P2, a filter flow path P3, a transmission flow path P4, a first outflow path P5a, and a second outflow path P5b, which will be described below, may all be provided on the same plane. Accordingly, when the flow paths P are arranged on the same plane, a front-to-rear width occupied by the flow paths may be maintained constant, so the flow path guide pack 100 may be miniaturized. Additionally, when the flow paths P are arranged on the same plane, a portion excessively bent in the flow paths may be removed, thereby facilitating the flow of water.

FIG. 14 illustrates the direction of water flow inside the flow path guide pack 100 with an arrow. For reference, FIG. 14 illustrates the discharge of mixed water mixed with cold water and hot water. As illustrated, cold water introduced into the first inlet IH may move along the first inflow path P1a (the direction of arrow {circle around (1)}). A first end part of the first inflow path Pa may be connected to the first inlet IH, and a second end part thereof may be connected to a first inlet pipe 142a of the thermostat 140. Reference numeral 112a denotes a first inlet point 112a connected to the first inlet pipe 142a.

Meanwhile, hot water introduced into the second inlet IH may move along the second inflow path P1b (the direction of arrow {circle around (2)}). A first end part of the second inflow path P1b may be connected to the second inlet IH, and a second end part thereof may be connected to a second inlet pipe 142b of the thermostat 140. Reference numeral 112b denotes a second inlet point 112b connected to the second inlet pipe 142b.

Cold water and hot water flowing into the thermostat 140 through the first inlet pipe 142a and the second inlet pipe 142b, respectively, may be mixed inside the thermostat 140. The thermostat 140 may mix incoming cold water and hot water with each other to control the temperature of the mixed water. In this case, the thermostat 140 may be regarded as a type of valve. In this embodiment, the thermostat 140 may implement the constant temperature function of maintaining the temperature of the mixed water around a set temperature. The thermostat 140 may control the ratio of cold and hot water mixed by adjusting the degree of the opening of the valve that opens and closes inside.

Reference numeral 112c denotes a mixed water discharge point 112c. The mixed water discharge point 112c may be connected to the discharge pipe 142c of the thermostat 140. Mixed water discharged through the discharge pipe 142c of the thermostat 140 may flow along the mixed water flow path P2, which starts at the mixed water discharge point 112c and ends at a flow rate control point 113a (the direction of arrow {circle around (3)}). The mixed water flow path P2 may be arranged between the first inflow path P1a and the second inflow path P1b. More precisely, some sections of the mixed water flow path P2 may be placed under the first inflow path P1a and above the second inflow path P1b.

The mixed water that reaches the flow rate control point 113a may flow into the flow rate controller 150. The flow rate controller 150 may be provided with a control inlet 152a (see FIG. 6) and a control outlet 152b. The control inlet 152a may be connected to the flow rate control point 113a. The control outlet 152b may be a portion through which water is discharged at a flow rate controlled through the flow rate controller 150. The control outlet 152b may be connected to a controlled water discharge point 113b of the flow path guide pack 100.

The filter flow path P3 may connect the controlled water discharge point 113b with a filter introduction point 114a. Through the filter flow path P3, control water may be provided to a filter inlet 162a (see FIG. 6) of the filter 160 (the direction of arrow {circle around (4)}). The controlled water that has passed through the filter 160 may be purified water. The purified water may be discharged through a filter outlet 162b of the filter 160. Reference numeral 114b denotes a filter discharge point 114b connected to the filter outlet 162b.

The transmission flow path P4 may be provided between the filter discharge point 114b and a power supply point 115. The transmission flow path P4 may be a flow path for transmitting the purified water to the generator 170. The purified water may be supplied to the generator 170 through the transmission flow path P4 (the direction of arrow {circle around (5)}).

In this embodiment, the power supply point 115 may not be connected to other points, and the flow path may be cut off at the power supply point 115. The power supply point 115 may be connected to a power generation inlet 172 (see FIG. 5) of the generator 170, so that purified water may be supplied to the generator 170. The purified water may be transmitted through the power generation inlet 172 to the generator 170 (the direction of arrow {circle around (5)}). The generator 170 may be operated through the pressure of the purified water.

Purified water that has passed through the generator 170 may be transmitted to the water discharge selector 180. Reference numeral 116 indicates a selection point 116 to which purified water discharged through the water discharge selector 180 is discharged. The selection point 116 may include a first selection point 116a, a second selection point 116b, and a third selection point 116c. The first selection point 116a may be connected to the first outlet OH1 through the first outflow path P5a. The purified water may be discharged to the first outlet OH1 through the first outflow path P5a. The second selection point 116b may be connected to the second outlet OH2 through the second outflow path P5b. The purified water may be discharged to the second outlet OH2 through the second outflow path P5b.

Finally, the third selection point 116c may be connected to the guide water discharge pipe 192 (see FIG. 29) through the third outflow path P5c. The purified water may be discharged to the third outlet OH3 through the third outflow path P5c. More precisely, the purified water may move to a water discharge point 117 through the third outflow path P5c (the direction of arrow {circle around (8)}). In addition, referring to FIG. 13, the purified water may move forward through a selector water discharge pipe 186 and the guide water discharge pipe 192 connected to the water discharge point 117 (the direction of arrow {circle around (3)}) in FIG. 13). The purified water moved forward may be discharged through the third outlet OH3 provided at the end of the guide water discharge pipe 192 (see an arrow in FIG. 29).

Accordingly, in the flow path guide pack 100, raw water may be introduced through the inlet IH, and then may flow to components through the flow paths P inside. Water (purified water) that has passed through the above components after passing through the inlet IH may be finally discharged through the outlet OH to the outside. Since the flow paths P are made integrally inside the flow path guide pack 100, the flow paths P inside the flow path guide pack 100 may have a large cross-sectional area compared to the volume of the flow path guide pack 100. Since the flow path guide pack 100 is dedicated to the transmission of water, efficient water flow is possible through the large volume of the flow paths P.

FIG. 15 illustrates a process in which external cold water is introduced and discharged through the third outlet OH3 without mixing with hot water. As illustrated, cold water flowing into the first inlet IH may move along the first inflow path P1a (the direction of arrow {circle around (1)}). Cold water introduced into the thermostat 140 through the first inlet pipe 142a may flow into the inside of the thermostat 140. The thermostat 140 may discharge the introduced cold water without mixing the introduced cold water with hot water.

Cold water discharged through the discharge pipe 142c of the thermostat 140 may flow along the mixed water flow path P2, which starts at the mixed water discharge point 112c and ends at the flow rate control point 113a (the direction of arrow {circle around (2)}). Mixed water (cold water) that has reached the flow rate control point 113a may flow into the flow rate controller 150. Cold water introduced into the inside of the flow rate controller 150 through the control inlet 152a of the flow rate controller 150 may be discharged through the control outlet 152b of the flow rate controller 150 after the discharge flow rate of the cold water is controlled.

The controlled water discharged to the control outlet 152b may be provided to the filter inlet 162a of the filter 160 through the filter flow path P3 (the direction of arrow {circle around (3)}). The controlled water that has passed through the filter 160 may become purified water. The purified water may be discharged through the filter outlet 162b of the filter 160. The purified water may be supplied to the generator 170 through the transmission flow path P4 (the direction of arrow {circle around (4)}).

Purified water that has passed through the generator 170 may be transmitted to the water discharge selector 180. In FIG. 15, a third selection flow path may be selected in the water discharge selector 180, and the purified water may be discharged to the third outlet OH3 through the third outflow path P5c (the direction of arrow {circle around (5)}).

Meanwhile, FIG. 16 illustrates a process in which external hot water is introduced and discharged through the second outlet OH2 without mixing with cold water. As illustrated, hot water flowing into the second inlet IH may move along the second inflow path P1b (the direction of arrow {circle around (1)}). Hot water introduced to the thermostat 140 through the second inlet pipe 142b may flow into the inside of the thermostat 140. The thermostat 140 may discharge the introduced hot water without mixing the introduced hot water with cold water.

The hot water discharged through the discharge pipe 142c of the thermostat 140 may flow along the mixed water flow path P2, which starts at the mixed water discharge point 112c and ends at the flow rate control point 113a (the direction of arrow {circle around (2)}). Mixed water (hot water) that reaches the flow rate control point 113a may flow into the flow rate controller 150. The hot water flowing into the interior of the flow rate controller 150 through the control inlet 152a of the flow rate controller 150 may be discharged through the control outlet 152b of the flow rate controller 150 after the discharge flow rate of the hot water is controlled.

The controlled water discharged to the control outlet 152b may be provided to the filter inlet 162a of the filter 160 through the filter flow path P3 (the direction of arrow {circle around (3)}). The controlled water that has passed through the filter 160 may be purified water. The purified water may be discharged through the filter outlet 162b of the filter 160. The purified water may be supplied to the generator 170 through the transmission flow path P4 (the direction of arrow {circle around (4)}).

Purified water that has passed through the generator 170 may be transmitted to the water discharge selector 180. In FIG. 16, a second selection flow path may be selected in the water discharge selector 180, and the purified water may be discharged to the second outlet OH2 through the second outflow path P5b (the direction of arrow {circle around (5)}).

Meanwhile, looking at the second flow path body 120, the second flow path body 120, like the first flow path body 110, may be made into a flat plate structure. Referring to FIGS. 11 and 12, the second path corresponding to the first path of the first flow path body 110 may be formed in a recessed form in the second flow path body 120. The second path may be connected to the first path to form one path.

The second flow path body 120 may be provided with a plurality of connectors 122, 123, 124, 125, 126, and 127. The connectors 122, 123, 124, 125, 126, and 127 are intended to connect the flow paths P with components disposed on the outside of the flow path guide pack 100. Some of the connectors 122, 123, 124, 125, 126, and 127 may constitute a portion through which water is discharged from the flow path guide pack 100. Accordingly, some of the connectors 122, 123, 124, 125, 126, and 127 may be considered to constitute an outlet.

The connectors 122, 123, 124, 125, 126, and 127 may be formed in the second flow path body 120 in a rear-to-front direction (an X-axis direction in FIG. 1), which is a coupling direction of the second flow path body 120 and the first flow path body 110. Accordingly, when the connectors 122, 123, 124, 125, 126, and 127 are open in the first direction in which the first flow path body 110 and the second flow path body 120 are combined with each other, the connectors 122, 123,124, 125, 126, and 127 may be arranged at various locations by using the wide surface of the second flow path body 120. In addition, when the connectors 122, 123, 124, 125, 126, and 127 are open in the first direction in which the first flow path body 110 and the second flow path body 120 are coupled to each other, components such as the generator 170 and the filter 160 may be arranged side by side on the front of the flow path guide pack 100.

The connector may include a temperature control connector 122 connected to the thermostat 140. The temperature control connector 122 may be connected to each of the first inlet pipe 142a, the second inlet pipe 142b, and the discharge pipe 142c of the thermostat 140. To this end, the temperature control connector 122 may include a first temperature control connector 122a, a second temperature control connector 122b, and a third temperature control connector 122c. The first temperature control connector 122a may be provided at a position corresponding to the first inlet point 112a of the first flow path body 110. The second temperature control connector 122b may be provided at a position corresponding to the second inlet point 112b. The third temperature control connector 122c may be provided at a position corresponding to the mixed water discharge point 112c.

The water discharge connector 127 may be connected to the water discharge point 117 of the first flow path body 110.

Referring to FIG. 10, the second flow path body 120 may be provided with fixing parts for fixing the parts. The fixing parts may protrude forward from the surface of the second flow path body 120 toward the front, that is, toward the cover plate 30. Fasteners (not shown) such as screws may be fastened to the fixing parts to fix components. Reference numeral 128a denotes a first fixing part for fixing the thermostat 140. Reference numeral 128b denotes a second fixing part for fixing the generator 170. Reference numeral 128c denotes a third fixing part for fixing the flow rate controller 150. Reference numeral 128d denotes a fourth fixing part for fixing the filter 160. Reference numeral 128e denotes a fifth fixing part for fixing the water discharge selector 180.

Referring to FIG. 17, the connection structure of the flow paths P of the flow path guide pack 100, the connectors 122, 123, 124, 125, 126, and 127 of the flow path guide pack 100, and other components is illustrated in a block diagram. As illustrated, the flow path guide pack 100 may be responsible for the inflow of raw water through the inlet IH, the discharge of purified water through the outlet OH, and connection between components. The flow path guide pack 100 may connect the remaining components to each other except for the connection of the generator 170 with the water discharge selector 180. Accordingly, in this embodiment, the flow paths P connecting components to each other may be focused on the flow path guide pack 100. Additionally, the flow paths P may be placed on the same plane, as described above. Therefore, a front-to-back thickness occupied by each of the flow paths P may be reduced, and each of the flow paths P may be made to have the same wide diameter.

FIG. 18 illustrates a state in which the selection point 116 through which purified water discharged through the water discharge selector 180 is discharged and the water discharge point 117 are enlarged. The third selection point 116c and the water discharge point 117 may be connected to each other by the third outflow path P5c. The water discharge point 117 may be connected to the third outlet OH3, and the third outlet OH3 may be a part that discharges the remaining water of the water supply device 10. For example, the residual water of the filter 160, the residual water of the first water discharge part 2, and the residual water of the second water discharge part 4 may be discharged through the water discharge point 117. In this case, a user may open the third selection flow path by manipulating a third selection lever 190c of the water discharge selector 180. Residual water that has passed through the third selection flow path and the outflow paths may be discharged through the third outlet OH3.

Reference numeral H1 denotes the height of the water discharge point 117. On the basis of the water discharge point 117, residual water remaining up to a position higher than the water discharge point 117 may be discharged to the third outlet OH3 through the water discharge point 117. In this case, the water discharge point 117 may be arranged at a position higher than the first selection point 116a which is a second end part of the first outflow path P5a relative to the direction of gravity (a vertical direction based on FIG. 18), the second selection point 116b which is a second end part of the second outflow path P5b, and the third selection point 116c. Accordingly, residual water at the height of the first selection point 116a, the second selection point 116b, and the third selection point 116c may not be discharged immediately, but may move to the water discharge point 117 through the third outflow path P5c to be discharged. Accordingly, when the water supply device 10 stops operating, residual water may be prevented from leaking little by little. In addition, since the water discharge point 117 is arranged higher than the first selection point 116a and the second selection point 116b, the water discharge point 117 may not interfere with the selection points 116.

Looking at the controller, the controller may include the thermostat 140 and the flow rate controller 150. Referring to FIGS. 5 and 6, the thermostat 140 may be provided with the first inlet pipe 142a, the second inlet pipe 142b, and the discharge pipe 142c.

More precisely, the first inlet pipe 142a may be connected to the first inlet point 112a of the first inlet pipe 142a. Hot water may flow into the second inlet pipe 142b. The second inlet pipe 142b may be connected to the second inflow path P1b of the flow path guide pack 100. More precisely, the second inlet pipe 142b may be connected to the second inlet point 112b of the second inlet pipe 142b. The cold water, hot water, or mixed water may be discharged through the discharge pipe 142c. The discharge pipe 142c may be connected to the mixed water discharge point 112c of the mixed water flow path P2.

In this embodiment, the thermostat 140 may implement a constant temperature function that maintains the temperature of the mixed water around a set temperature. The thermostat 140 may control the ratio of cold and hot water mixed by controlling the degree of the opening of a valve that opens and closes inside.

The flow rate controller 150 may control the discharge amount of mixed water and transmit the controlled mixed water to the filter 160. The flow rate controller 150 may be provided with the control inlet 152a and the control outlet 152b. The mixed water may flow into the control inlet 152a.

In addition, the pre-carbon filter 160 may remove volatile organic substances, and adsorb and remove chlorine and trihalomethane (THM). The membrane filter 160 is intended to remove fine substances and may include microfiltration (MF), ultrafiltration (UF), reverse osmosis (RO), etc. depending on the size of pores.

The interior of the inner housing 163a may be divided into the first filter space FS1 at an outer side and the second filter space FS2 at an inner side relative to the filter body 163b. Controlled water introduced into the first filter space FS1 may be filtered while passing through the filter body 163b and then discharged to the second filter space FS2. The first filter space FS1 may be connected to the raw water inlet 164a. The second filter space FS2 may be connected to the purified water outlet 164b.

The filter cover 165 may be provided on the lower end of the filter part 163. The filter cover 165 may be provided to be integrated with the inner housing 163a. The filter cover 165 may be exposed to the lower part of the casing 20 when the filter 160 is mounted on the water supply device 10. The filter cover 165 may be provided with the handle 165′.

FIG. 21 illustrates a state in which mixed water is introduced into the flow rate controller 150 and a state in which control water is purified through the filter body 163b. The mixed water may flow into the flow rate controller 150 through the mixed water flow path P2 (the direction of arrow {circle around (1)}). The mixed water moving along the mixed water flow path P2 may flow into the control inlet 152a of the flow rate controller 150 through the flow rate control point 113a. Controlled water whose flow rate is controlled in the flow rate controller 150 may be discharged to the control outlet 152b of the flow rate controller 150 (the direction of arrow {circle around (2)}). The controlled water may move along the filter flow path P3 from the controlled water discharge point 113b.

The left side of FIG. 21 illustrates a direction in which the controlled water passes through the filter body 163b (the direction of arrow {circle around (3)}). Water moving toward the center of the filter part 163 through the filter body 163b may be purified while passing through the filter body 163b. The purified water purified in this way may be supplied to the generator 170.

FIG. 22 illustrates a state in which the controlled water enters and exits the filter 160. Controlled water moving through the filter flow path P3 may reach the filter introduction point 114a, and then may flow into the filter inlet 162a of the filter 160 (the direction of arrow {circle around (1)}). Water purified through the filter 160 may be discharged through the filter outlet 162b (the direction of arrow {circle around (2)}). The discharged purified water may be supplied to the generator 170 through the transmission flow path P4 starting at the filter discharge point 114b.

Referring to FIG. 23, the purification of controlled water through the filter 160 is illustrated in detail. The controlled water may be introduced through the filter inlet 162a and then flow into the raw water inlet 164a of the inner housing 163a. The introduced controlled water may flow into the first filter space FS1 (the direction of arrow {circle around (1)}). The controlled water in the first filter space FS1 may pass through the filter body 163b and be discharged to the second filter space FS2 (direction of arrow {circle around (2)}). In this process, the controlled water may be purified. Finally, purified water in the second filter space FS2 may be discharged through each of the purified water outlet 164b of the inner housing 163a and the filter outlet 162b of the filter housing 161.

FIGS. 24 to 26 illustrate the generator 170 and the water discharge selector 180. Looking at the generator 170, the generator 170 may be a water-flow generator 170 that uses high-speed water flow caused by the flow of purified water. Although not shown, the inside of the generator 170 may include an impeller that is rotated by pressure of purified water and a small power generation means connected to the impeller. Electrical energy generated by the power generation means may be transferred to a battery. The generator 170 may have a built-in battery, or the display 70 may be provided with a battery. The generator 170 and the display 70 may be electrically connected to each other through a wire (not shown).

The generator 170 may be provided with the power generation inlet 172 and a power generation outlet 182. The power generation inlet 172 may be a part through which purified water is introduced, and the power generation outlet 182 may be a part through which purified water that has completed power generation is discharged. The power generation inlet 172 may be connected to the power supply point 115 (see FIG. 14) of the transmission flow path P4. Reference numeral 171 may be a fixing bracket 171 for fixing the generator 170. The fixing bracket 171 may be fixed to a mounting plate 184 of the water discharge selector 180. The power generation outlet 182 may be regarded as a part of the water discharge selector 180.

The power generation outlet 182 may be open downward. The power generation outlet 182 may be connected to a selector entrance 181a of the water discharge selector 180. That is, since the power generation outlet 182 and the selector entrance 181a are directly connected to each other, the generator 170 and the water discharge selector 180 may be connected to each other without going through the flow path guide pack 100. For another example, the power generation outlet 182 and the selector entrance 181a may each be connected to the flow path guide pack 100 and connected to each other by the flow path guide pack 100.

Referring to the water discharge selector 180, the water discharge selector 180 may be provided with a selector housing 183 having a water storage space 181 (see FIG. 27) provided therein. The selector housing 183 may be made into an approximately hexahedral structure. The selector entrance 181a may be open on an upper portion of the selector housing 183. The selector entrance 181a may be connected to the water storage space 181a. The selector housing 183 may be provided with the mounting plate 184 to support the fixing bracket 171 of the generator 170.

Accordingly, in this embodiment, the generator 170 and the water discharge selector 180 may be arranged at different heights. When the generator 170 and the water discharge selector 180 are stacked in a vertical direction, a total volume occupied by the generator 170 and the water discharge selector 180 in the installation space 23 may be reduced. When the generator 170 and the water discharge selector 180 are stacked in the vertical direction, a short flow path that directly connects the generator 170 and the water discharge selector 180 to each other may be formed.

A selector cover 185 may be provided on the front of the selector housing 183. The selector cover 185 may have a flat plate structure. The selector cover 185 may cover the front surface of the selector housing 183. Referring to FIG. 28, the selector cover 185 may be provided with a plurality of holes. The holes, which are lever passage holes 185a, may be parts through which the selection levers 190 pass.

The selector cover 185 may be provided with the selector water discharge pipe 186. The selector water discharge pipe 186 may extend in the front-to-rear direction on the upper portion of the selector cover 185. A connection channel 187 may be provided inside the selector water discharge pipe 186. The connection channel 187 may be connected to the water discharge point 117 of the third outflow path P5c. The connection channel 187 may be connected to the guide water discharge pipe 192 of the movement guide 191. Accordingly, purified water that has passed through the third outflow path P5c and the connection channel 187 may be discharged through a guide channel 192a of the guide water discharge pipe 192. As previously described, since the third outlet (see FIG. 29) is provided on one end part of the guide water discharge pipe 192, purified water may ultimately be discharged through the third outlet OH3.

The selector housing 183 may be provided with a plurality of flow path blocks 188. The flow path blocks 188 may move linearly in front-to-rear directions or rotate. When the flow path blocks 188 move linearly or rotate, selection flow paths (not shown) provided in the flow path blocks 188 may be selectively connected to the water storage space 181a. The selection flow paths connected to the water storage space 181a may receive purified water and transmit the purified water to the outflow path.

In this embodiment, a total of three flow path blocks may be included. The selection flow paths P provided in the three flow path blocks 188, respectively, may be connected to the first outflow path P5a, the second outflow path P5b, and the third outflow path P5c, respectively. The three flow path blocks 188 may connected to the three selection levers 190, respectively, and may be operated by the selection levers 190.

More precisely, a first flow path block 188a among the flow path blocks 188 may be provided with a first selection flow path connected to the first end part of the first outflow path P5a. A second flow path block 188b among the flow path blocks 188 may be provided with the second selection flow path connected to the first end part of the second outflow path P5b. A third flow path block 188c among the flow path blocks 188 may be provided with the third selection flow path connected to the first end part of the third outflow path P5c.

Referring to FIGS. 25 and 26, when a user presses the third selection lever 190c in the direction of an arrow, the third selection lever 190c may protrude forward. Together with the third selection lever 190c, the third flow path block 188c on a rightmost side may also protrude forward. In this case, a connection flow path provided in the third flow path block 188c may be connected to the water storage space 181a. In this embodiment, each of the flow path blocks may be provided with a spring (not shown), and the spring may provide an elastic force to each of the selection lever and the flow path block so that the selection lever and the flow path block protrude forward.

Referring to FIG. 27, the selector housing 183 may be provided with the selector outlets 189. The selector outlets 189 may be connected to the selection flow paths of the flow path blocks 188, respectively. The selector outlets 189 may be connected to the outflow paths P5a, P5b, and P5c. Accordingly, the selector outlets 189 may connect the selection flow paths with the outflow paths P5a, P5b, and P5c.

The selector outlets 189 may include the first selector outlet 189a, the second selector outlet 189b, and the third selector outlet 189c. The first selector outlet 189a may be connected to the first selection point 116a (see FIG. 14). The second selector outlet 189b may be connected to the second selection point 116b (see FIG. 14). The third selector outlet 189c may be connected to the third selection point 116c (see FIG. 14).

The selector outlets 189 may have the same heights. However, the first outflow path P5a, the second outflow path P5b, and the third outflow path P5c starting from the first selection point 116a, the second selection point 116b, and the third selection point 116c, respectively, may have different heights in at least some sections. This is intended to prevent the first outflow path P5a, the second outflow path P5b, and the third outflow path P5c from interfering with each other.

Referring to FIGS. 28 and 29, the selector cover 185 and the movement guide 191 are illustrated. The movement guide 191 may guide the movements of the selection levers 190. The movement guide 191 may be arranged on the front of the selector housing 183. In this embodiment, the movement guide 191 may be fixed to the cover plate 30. The movement guide 191 may have a plurality of guide holes 191a, through which each of the selection levers 190 may move in a straight line.

The movement guide 191 may be provided with the guide water discharge pipe 192. The guide water discharge pipe 192 may be arranged on the upper portion of the movement guide 191. The guide water discharge pipe 192 may extend in the front-to-rear direction, that is, in the coupling direction of the first flow path body 110 and the second flow path body 120. The guide channel 192a may be provided inside the guide water discharge pipe 192. The guide channel 192a may be connected to the connection channel 187 of the selector water discharge pipe 186. As illustrated in FIG. 29, when a portion of the guide water discharge pipe 192 is inserted into the selector water discharge pipe 186, the guide channel 192a may be connected to the connection channel 187.

Referring to FIG. 13, the first end of the selector water discharge pipe 186 may be connected to the water discharge point 117 of the third outflow path P5c. The connection channel 187 may be connected to the guide water discharge pipe 192 of the movement guide 191. Accordingly, purified water that has passed through the third outflow path P5c and the connection channel 187 may be discharged through the guide channel 192a of the guide water discharge pipe 192.

Referring to FIG. 29, the guide channel 192a may be formed in an approximately L-shape. The first end of the guide channel 192a may be connected to the connection channel 187. The third outlet OH3 may be provided on the second end of the guide channel 192a. Since the lower water outlet 25 (see FIG. 3) described above is disposed at the lower part of the third outlet OH3, water discharged through the third outlet OH3 may be discharged to a bathtub through the lower water outlet 25.

FIG. 30 illustrates a second embodiment of the water supply device according to the present disclosure 10. As shown, the water supply device 10A may include a water discharge selector 290 that rotates. The water discharge selector 290 can be rotated in the direction of an arrow. When the water discharge selector 290 is rotated, purified water passing through the flow path guide pack 100 may be selectively discharged through the first outlet OH1, the second outlet OH2, or the third outlet (not shown). Reference numeral 290a refers to a bathtub faucet, and the bathtub faucet 290a may be connected to the third outlet disposed inside.

For example, when the water discharge selector 290 is rotated counterclockwise, purified water may be discharged through the first outlet OH1. When the water discharge selector 290 is rotated clockwise, purified water may be discharged through the second outlet OH2. When the water discharge selector 290 is aligned toward the front as shown in FIG. 30, purified water may be discharged through the third outlet. For this operation, a branch valve connected to the water discharge selector 290 may be disposed inside the water supply device 10A.

FIGS. 31 and 32 illustrate a third embodiment of a water supply device 10B according to the present disclosure. As illustrated in FIG. 31, the water supply device 10B may include only one control knob 390. The control knob 390 may be rotated in a first direction (a direction of arrow {circle around (1)}) or in a second direction (a direction of arrow {circle around (2)}). The first direction is based on the Y-axis of FIG. 1 as the center of rotation, and the second direction is based on the X-axis of FIG. 1 as the center of rotation.

When the control knob 390 is rotated in the first direction, the controller provided inside the water supply device 10B may control a discharge flow rate. In addition, when the control knob 390 is rotated in the second direction, the controller provided inside the water supply device 10B may control a discharge temperature. Accordingly, in this embodiment, the controller may control both flow rate and temperature. Reference numeral 391 denotes a holding portion of the control knob 390.

FIG. 32 illustrates the structure of the first flow path body 110 of the flow path guide pack 100 constituting the water supply device according to the present disclosure 10B according to the third embodiment. Compared to the first embodiment described above, the flow path for flow rate control is omitted in the flow path guide pack 100. In the third embodiment, the temperature and flow rate of water may be controlled by one controller. To this end, the first flow path body 110 of the flow path guide pack 100 may include the first inflow path P1a and the second inflow path P1b connected to the controller. In addition, mixed water (controlled water) with controlled mixing and flow rate may be supplied to the generator 170 through the mixed water flow path P2 and a power generation path P4.

In addition, a controller that controls the flow rate or temperature of water discharged through the outlet may be placed in the installation space. The flow path guide pack may be provided with a connector connecting the controller and each of the flow paths to each other. The connector may be open in a first direction in which the first flow path body and the second flow path body are coupled to each other.

The controller that controls the flow rate or temperature of water discharged through the outlet may be placed in the installation space. The flow path guide pack may be provided with the connector connecting the controller and each of the flow paths to each other. The connector may be open towards the front surface of the casing.

The plurality of flow paths may be arranged on the same plane inside the flow path guide pack. In this case, while a front-to-rear directional thickness occupied by the flow paths is reduced, the flow paths may be made to have the same wide diameters.

The first flow path body and the second flow path body may include a first close contact part and a second close contact part, respectively. The first close contact part and the second close contact part may be in close contact with each other to form the flow paths. Accordingly, when the first flow path body and the second flow path body are combined with each other, the flow paths may be naturally formed.

In a portion in which the first flow path body and the second flow path body face each other, the flow paths may be formed in the remaining portion except for portions on which the first close contact part and the second close contact part are in close contact with each other. Accordingly, a wide space in which the flow paths are formed may be secured inside the flow path guide pack.

The first close contact part and the second close contact part may be fused to each other by using vibration fusion, heat fusion, or ultrasonic fusion. These fusion methods may allow the flow paths to be formed inside the flow path guide pack without separate fasteners or sealing parts.

The first flow path body and the second flow path body may be combined with each other in the first direction. The inlet may be open in the first direction. The inlet may be made large by utilizing the large area of the front or rear surface of the flow path guide pack, and the inflow of water may be efficiently performed through the inlet.

The first flow path body and the second flow path body may be combined with each other in the first direction. The flow paths may be formed in a direction different from the first direction. Accordingly, while the flow paths are ensured wide, the flow path guide pack may be made thin.

The controller that controls the flow rate or temperature of water discharged through the outlet and the filter that purifies water introduced through the inlet may be arranged in the installation space. On the basis of a front-to-rear direction, which is the assembly direction of the first flow path body and the second flow path body, each of the controller and the filter may be entirely or partially arranged to overlap the front surface of the flow path guide pack. Accordingly, the flow path guide pack and components may be efficiently arranged in a narrow space.

The flow paths may include an inflow path connecting the inlet with the controller, a filter flow path connecting the controller with the filter, and an outflow path connecting the filter with the outlet. The inflow path, the filter flow path, and the outflow path may be provided on the same plane.

A generator that generates electricity by the hydraulic pressure of the introduced water may be placed in the installation space. The controller, the filter, and the generator may be connected to each other through the flow paths.

In water flow paths formed by the flow paths, the filter may be arranged closer to the inlet than the generator, so that water purified through the filter may be transmitted to the generator. Accordingly, the generator may be prevented from being damaged by impurities contained in water.

The inlet may include a first inlet to which external cold water is supplied and a second inlet to which external hot water is supplied. The flow paths may include a first inflow path connecting the first inlet and the controller to each other.

The filter may be arranged in the installation space, and the thermostat and the flow rate controller may be arranged on opposite sides of the filter with the filter as a center thereof.

The filter may be arranged in the installation space. The filter may receive water that has passed through the controller through the flow path guide pack. Water purified through the filter may be transmitted to the outlet through the flow path guide pack.

The filter may be stored in the installation space in the second direction different from the first direction in which the first flow path body and the second flow path body are combined with each other.

The filter may include a filter housing having a filter storage part provided therein, and a filter part that is stored in the filter storage part and purifies water. The filter part may be stored in the filter storage part in the second direction different from the first direction in which the first flow path body and the second flow path body are combined with each other.

The outlet may include a plurality of outlets that is independent of each other. A water discharge selector having a plurality of selection flow paths may be arranged in the installation space. Water discharged from the controller may be discharged through any one of the selection flow paths and transmitted to any one of the plurality of outlets.

The generator that generates electricity by the pressure of the introduced water may be arranged in the installation space. The generator and the water discharge selector may be respectively arranged at different heights inside the installation space.

Water discharged from the flow path guide pack may sequentially pass through the generator and the water discharge selector and then be transmitted to the outlet.

The movement guide may include a guide water discharge pipe whose first end part is inserted into the flow path guide pack. The guide water discharge pipe may be connected to the third outflow path of the flow path guide pack.

As described above, the water supply device according to the present disclosure and the faucet including the same may have the following effects.

According to the present disclosure, the flow path guide pack that guides the flow of water may be arranged inside the water supply device. The flow path guide pack may be provided with flow paths that are independent of the internal space of the water supply device, allowing water introduced from the outside to be branched and discharged. Since water flows through the flow path of the guide pack, complex flow paths may be implemented without a plurality of hoses. Accordingly, the internal structure of the water supply device may be simplified, and a decrease in a flow rate due to hoses being folded may be prevented.

In addition, in the flow path guide pack, two flow path bodies may be coupled to each other to form flow paths therebetween. The two flow path bodies may be made of resin materials and then may be coupled to each other by a method such as fusion. Accordingly, in the water supply device of the present disclosure, complex flow paths may be implemented without using a casting method, and the cross-sectional area of a flow path may be made wider compared to the volume to facilitate the flow of water, which also has the effect of making the water supply device lighter.

Furthermore, according to the present disclosure, the flow path guide pack may be manufactured by using a fusion method after injection molding, thereby reducing assembly time and being advantageous in mass production.

Additionally, according to the present disclosure, the flow path guide pack may be responsible for the inflow/branch/discharge of water, and thus the internal structure of the water supply device may be simplified even if components such as a filter, a water-flow generator, and a thermostat are mounted in the water supply device.

Particularly, according to the present disclosure, since the flow path guide pack is composed of two flow path bodies with thin flat plate structures, the flow path guide pack may occupy a small volume inside the water supply device and may be arranged in an upright position. Accordingly, a large free space may be secured inside the water supply device, and thus may be used to install various components, thereby adding various functions while miniaturizing the water supply device.

In addition, according to the present disclosure, the plurality of flow paths may be arranged on the same plane inside the flow path guide pack. Accordingly, when the flow paths are arranged on the same plane, a front-to-rear width occupied by the flow paths may be maintained constant, thereby allowing the flow path guide pack to be miniaturized. In addition, when the flow paths are arranged on the same plane, an excessively bent portion in the flow paths may be eliminated, thereby allowing water to flow efficiently.

Additionally, according to the present disclosure, the inlet of water may be open in the same direction as the first direction in which the first flow path body and the second flow path body constituting the flow path guide pack are assembled with each other. The inlet may be made to be large by utilizing the large area of the front or rear surface of the flow path guide pack. Accordingly, water may be efficiently introduced through the inlet, and water pressure around the inlet may be reduced, thereby increasing the durability of the flow path guide pack.

Furthermore, according to the present disclosure, the flow path guide pack may be detachably arranged inside the water supply device, so when the flow paths are blocked or damaged, only the flow path guide pack may be removed and replaced. That is, the maintainability of the water supply device may be high since only the flow path guide pack is replaced without the need to replace the entirety of water supply device.

In addition, according to the present disclosure, the filter may be placed inside the water supply device to discharge incoming water after purifying the incoming water. Since the filter is arranged inside the body of the water supply device rather than a final discharge device such as a shower head, there is no need to install a filter on each of a plurality of discharge devices. Therefore, the number of parts (filters) for purification may be reduced, and replacement of the filter may become easier.

Particularly, according to the present disclosure, the filter may be mounted upward from the lower portion of the water supply device. Accordingly, the replacement of the filter may be facilitated, and since the entrance of the filter is usually covered, aesthetics may be improved.

Furthermore, since the flow path guide pack takes charge of the flow paths, the wide internal space of the water supply device may be secured, so the capacity of the filter may be increased. Accordingly, the replacement cycle of the filter may be increased, and usability of the water supply device may be improved.

Additionally, according to the present disclosure, the water-flow generator may be installed in the water supply device. The water-flow generator may use water pressure to generate electrical energy and can supply the electrical energy to the display. According to the present disclosure, since the water-flow generator is arranged inside the main body of the water supply device rather than the final discharge device such as the shower head, the water-flow generator may provide various information to a user through the display of the body or utilize communication means or lighting devices.

In addition, according to the present disclosure, in the water flow paths, the water-flow generator may be arranged behind the filter, so that the generator may be operated by purified water. In this case, water from which impurities have been removed may be supplied to the water-flow generator, so the durability of the water-flow generator may be improved.

Additionally, according to the present disclosure, the water discharge selector may be arranged between the flow path guide pack and the outlet, so the discharge direction of water may be selected. For example, a user may discharge water through any one of a handheld showerhead, rain showerhead, or bathtub faucet. In the present disclosure, rather than controlling the discharge direction of water that has already been discharged to the outside of the water supply device, the discharge direction of water may be determined in advance inside the water supply device. Accordingly, before the pressure of water increases, the discharge direction of the water may be selected, so a force required to manipulate the water discharge selector may be reduced and convenience of use may be improved.

Furthermore, according to the present disclosure, inside the water supply device, the water-flow generator and the water discharge selector may be arranged to have a stacked structure at different heights. Since water that has passed through the water-flow generator is directly supplied to the water discharge selector, a flow path connecting the water-flow generator and the water discharge selector to each other may be implemented to have a minimum length, and the internal space of the water supply device may also be utilized effectively.

In addition, according to the present disclosure, the water supply device may be provided with a thermostat that controls the temperature of water and a flow rate controller that controls a flow rate. In this case, the thermostat and the flow rate controller may be arranged symmetrically on opposite ends of the body of the water supply device, and through this, the water supply device may provide a unified aesthetics.

Additionally, the filter, the water-flow generator, and the water discharge selector may be arranged in an empty space between the thermostat and the flow rate controller. Through this arrangement, the internal space of the water supply device may be utilized efficiently.

In addition, according to the present disclosure, residual water remaining in the flow path and the shower head may be discharged in a direction desired by a user through the water discharge selector. In this case, when the bathtub faucet is selected, the residual water may be efficiently discharged through the bathtub faucet, which is placed relatively low, even without lowering the height of the shower head.
