The water supply passage 60 may include a supplied water passage 61 connecting the water supply source 1 including a water pipe provided outside the main body 11 to the filter device 40 provided in the main body 11, a purified water passage 62 for guiding the water purified in the filter device 40 to the dispenser 20, a cooled water passage 63 for guiding the water purified in the filter device 40 to the dispenser 20 via the water tank 50, and an ice making passage 64 branched or extending from the purified water passage 62 to guide the water purified in the filter device 40 to the ice making device 30.
The supplied water passage 61 may extend from the water supply source 1 to the inside of the main body 11 and be connected to the filter device 40. Here, the supplied water passage 61 includes at least two tubes with respect to the main body 11. The at least two tubes may be connected to a fitting member 611. The fitting member 611 may be disposed on a rear surface of the main body 11 to allow a user to selectively separate the tube of the supplied water passage 61 that is connected to the water supply source 1. Also, the fitting member may be connected to a sterilization device (see reference numeral 70 of
A water supply valve 612 may be provided in the supplied water passage 61. The water supply valve 612 may open the supplied water passage 61 to determine water supply into the filter device 40. The water supply valve 612 may be provided in one side of the main body 11. Also, the water supply valve 612 may be integrated with the fitting member 611.
The filter device 40 may be disposed in the refrigerating compartment 13. In this case, the supplied water passage 61 may extend up to the inside of the refrigerating compartment 13. A water purifying passage 65 may be defined within the filter device 40. The water purifying passage 65 may be connected to the supplied water passage 61 to purify the water supplied from the water supply source while passing the filter device 40.
The purified water passage 62 may connect the filter device 40 to the dispenser 20. The purified water passage 62 may extend from an outlet of the filter device 40 to a side of the dispenser 20 to supply the water purified in the filter device 40 to the dispenser 20.
The purified water passage 62 may extend from the refrigerating compartment 13 in which the filter device 40 is disposed to the freezing compartment door 14 in which the dispenser 20 is disposed. Also, the purified water passage 62 may pass through a hinge (see reference numeral 16 of
Also, a purified water valve 622 may be provided in the purified water passage 62. The purified water value 622 may open the purified water passage 62 to selectively discharge the purified water to be dispensed into the dispenser 20. The purified water valve 622 may, for example, be a three way valve so that water supplied from the purified water passage 62 is divided and thus supplied into the dispenser 20 and the ice making device 30.
That is, the purified water valve 622 may be provided in the purified water passage 62. Also, the purified water passage 62 may be divided from the dispenser 20 or the freezing compartment door 14 and connected to the ice making passage 64 defined toward the ice making device 30. Thus, according to an operation of the purified water valve 622, the purified water passing through the filter device 40 may be directly dispensed into the dispenser 20 or supplied into the ice making device 30.
According to the embodiment, since the purified water and the cooled water are separately dispensed from the dispenser, when the dispensing of the purified water is selected, the dispensing of the cooled water may be prevented to reduce power consumption that is required for cooling the purified water.
The more the number of passages passing through the hinge increases, the more the possibility of the damage of the passage due to the twisting of the passage while the door rotates increases. Also, since the hole of the hinge, through which the passage passes, increases in size, the hinge may increase in size.
According to the embodiment, the two purified water passages may not be respectively connected to the dispenser 20 and the ice making device 30 by individually passing through the hinge. That is, the one purified passage 62 may pass through the hinge and then be branched by the purified water valve 622 within the freezing compartment door 14 and be connected to the dispenser 20 and the ice making device 30 to prevent the hinge from increasing in size and minimize the damage of the purified water passage while the door rotates.
Also, the purified water supplied through the ice making passage 64 may have a relative high temperature to reduce (e.g., prevent) freezing of water within the ice making passage 64 disposed in the freezing compartment door 14, thereby stably supplying water into the ice making device 30.
The cooled water passage 63 may extend from the refrigerating compartment 13 to the refrigerating compartment door 15. The cooled water passage 63 may be configured so that the water purified in the filter device 40 is supplied into the dispenser 20 after being cooled by passing through the water tank 50.
Here, the cooled water passage 63 may also be guided into the refrigerating compartment door 15 through the hinge (see reference numeral 16 of
The cooled water passage 63 may be branched from the outlet-side purified water passage 62 of the filter device 40 and then be connected to the water tank 50. Also, a cooled water valve 632 may be provided in the cooled water passage 63 to selectively open or close the cooled water passage 63 so that the cooled water to be dispensed into the dispenser 20 is selectively discharged.
The cooled water valve 632 may be provided in the cooled water passage 63 between the water tank 50 and the dispenser 20. The water supply into the dispenser 20 may be determined by the opening/closing of the cooled water valve 632.
Here, the cooled water passage 63 and the purified water passage 62 may be classified according to whether the passages 63 and 62 pass through the water tank 50. That is, since a water passage connected to the water tank 50 may be a cooled water passage, passages except for the cooled water passage may be purified water passages. For instance, the water passing through the water tank 50 may be cooled by the cool air within the refrigerating compartment to become cooled water. Also, the water that does not pass through the water tank 50 may be supplied into the dispenser 20 or the ice maker while being maintained at an original temperature of the water.

A support member 132 may be disposed on a side of the refrigerating compartment 13. The support member 132 may support the receiving member 131 and the filter device 40 upward. The support member 132 may be disposed on a bottom surface of the refrigerating compartment 13 or a top surface of another receiving member. Also, the support member 132 may have a plate shape that horizontally partitions the inside of the refrigerating compartment 13.
The top surface of the support member 132 may be divided into two areas, such as a receiving member mounting area 133 on which the receiving member 131 is mounted and a filter device mounting area 134 on which the filter device 40 is mounted. Also, a pair of entrance guides 135 for guiding forward and backward sliding of the receiving member 131 may be disposed on each of both sides of the receiving member mounting area 133.
Also, the filter device 40 may be disposed on the filter device mounting area 134 between the receiving member 131 and an inner wall of the refrigerating compartment 13. Further, the filter device 40 may have a front and top surface that is flush with those of the receiving member 131. Thus, the filter device 40 may be in unity with the receiving member 131 inside the refrigerating compartment 13. In addition, a shelf 136 may be mounted above the filter device 40 and the receiving member 131 to cover the receiving member 131 and the filter device 40 at the same time.
Rear surfaces of the receiving member 131 and the filter device 40 may be spaced apart from a rear wall of the refrigerating compartment 13 and the water tank 50 may be disposed at the rear sides of the receiving member 131 and the filter device 40. In this example, the water tank 50 may be accommodated in the space. That is, the water tank 50 may have a size, which is enough to be accommodated between the receiving member 131 and filter device 40 and the wall of the refrigerating compartment 13, to store water therein. Water purified by the filter device 40 may be stored n the water tank 50. Then, the water may be cooled by cool air within the refrigerating compartment, and thus, the cooled water may be supplied into the dispenser 20.
Also, the water supply passage 60 is connected to the water tank 50. Thus, the water tank 50 may be fluidly connected to the filter device 40 by the water supply passage 60. Further, the cooled water passage 63 connected to the dispenser 20 may be disposed in a space in which the water tank 50 is disposed. The cooled water valve may be fixedly mounted on the rear wall of the refrigerating compartment 13 that corresponds to an upper side of the water tank 50. For safety, the cooled water valve 632 may be covered by a valve cover 137. As described above, portions of the water tank 50, the cooled water valve 632, and the water supply passage 60 may be disposed in the space, in which the water tank 50 is disposed, e.g., a space defined between the rear wall of the refrigerating compartment and the rear surfaces of the receiving member 131 and the filter device 40.
As described above, the receiving member 131 may have the same length as the filter device 40 in forward and backward directions. Also, the front surface of the receiving member 131 may be flush with that of the filter device 40.
According to the embodiment, the plurality of filters may be vertically disposed and also be disposed in the space between the drawer and the sidewall of the refrigerating compartment in the front and rear direction to maximally secure the food storage space such as the drawer.
If each of the plurality of filters is disposed to extend in a left and right direction within the refrigerating compartment, when the water leakage occurs at the connection portion between the plurality of filters, the leaking water may be spread to the whole refrigerating compartment. However, according to the current embodiment, since the plurality of filters are vertically disposed and also disposed to extend in the front and rear direction, even through the water leakage occurs, the contact between the leaking water and the refrigerating compartment may be minimized.
Also, according to the current embodiment, the water tank may be disposed outside the case between the receiving member such as the drawer and the rear sidewall of the refrigerating compartment. Thus, since the water tank has a diameter that is greater than that of the filter, the storage capacity of the cold water may increase to prevent the case from unnecessarily increasing in size. If the water tank has a diameter that is equal or similar to that of the filter, the reduction of the storage capacity of the cold water may be easily detected.
Referring to
In some implementations, the case 41 may have a rectangular shape with an opened front surface. A plurality of filters 42 may be vertically arranged within the case 41 in a state where each of the plurality of filters 42 is horizontally disposed. Also, a case cover 44 may be disposed on a front surface of the case 41. The case cover 44 may rotate about the opened cover of the case 41 to cover the case 41. When the case cover 44 is closed, the front surface of the case cover 44 may be flush with that of the receiving member 131.
A plurality of insertion holes into which the plurality of filters 42 are respectively inserted may be defined in the case 41.
Also, a mount guide 45 may be disposed within the case 41. The mount guide 45 may extend in a direction parallel to an insertion direction of the filters 42. Each of the filters 42 may extend by a predetermined length from a point that is spaced from a connector 43 to which the filter 42 is fixed. The mount guide 45 may protrude from each of left and right surfaces of the case 41 in a direction opposite to each other, e.g., in a central direction of the case 41. Also, the mount guide 45 may have a curvature corresponding to an outer diameter of the filter 42. Thus, when the filter 42 is mounted, the filter 42 may be easily mounted to the connector 43.
A drain member 46 may be provided in the case 41. For example, the drain member 46 may be provided in an inner lower portion of the case 41, e.g., a bottom surface of the case 41. The drain member 46 may collect remaining water that is generated when the filter is detached. The drain member 46 may be provided in the bottom surface of the case 41 and have the same structure as a tray.
The drain member 46 may have an inclined surface 461 that is inclined downward from a rear portion thereof to guide water dropping from an upper side thereof to a front side. Also, an opening 462 for discharging the water collected by the drain member 46 may be defined in the drain member 46 or the case 41. For example, the opening 462 may be defined in the front surface of the case 41, more particularly, in a lower portion of the front surface of the case 41.
The filter 42 may be inserted into the case 41 and the plurality of filters 42 may have functions different from each other. For example, a reverse osmosis pressure filter may be used as the filter 42. In addition, three or more filters 42 may be combined with each other.
Also, the connector 43 may be disposed within the case 41. The connector 43 may include a bracket 47 fixed to the rear surface of the case 41, at least one socket 48 mounted on the bracket 47, and two stem connectors 49 provided on left and right sides of the bracket 47. The bracket 47 may be fixed to the inner surface of the case 41 to fix the filter 42 when the filter 42 is mounted. Also, the supplied water passage 61 may be connected to a first stem connector 491 that is disposed at the left side of the bracket 47, and the purified water passage 62 may be connected to a second stem connector 492 that is disposed at the right side of the bracket 47. Also, the two stem connectors 49 may be connected to each other through the water purifying passage 65. The water purifying passage 65 may communicate with the plurality of filters 42. Thus, the water purifying passage 65 may be defined as a passage that passes through the filter 42 from the first stem connector 491 to extend to the second stem connector 492.
A plurality of socket mount parts 471 may protrude from points of the bracket 47, which are spaced apart from each other, respectively. Also, the socket 48 may be mounted between the socket mount parts adjacent to each other. Here, the socket 48 may be rotatably mounted with respect to the water purifying passage 65.
Thus, when an end of the filter 42 is inserted into the socket 48 while the filter 42 is mounted, the socket 48 and the end of the filter 42 may be aligned with each other while being rotated. Thus, the socket 48 and the filter 42 may be coupled to each other in position.
The socket 48 may include a head part 481 mounted on the socket mount part 471 and a receiving part 482 in which the end of the filter 42 is accommodated. The head part 481 may be disposed between two adjacent socket mount parts 471 and may be rotatably mounted on the socket mount part 471. Also, the receiving part 482 may have a shape corresponding to that of the end of the filter 42. Further, a fitting member may be provided on the receiving part 482 that supplies water into the receiving part 482 when the filter is mounted, and prevents water from leaking when the filter 42 is separated. In some examples, a separate cap may be mounted to prevent water from leaking after the filter 42 is separated.
The plurality of socket mount parts 471 may be connected by the water purifying passage 65. The water purifying passage 65 may be provided as one tube to pass through the socket mount parts 471 or may include a plurality of tube structures connecting the socket mount parts 471 to each other. The water purifying passage 65 may be connected to the supplied water passage 61 and the purified water passage 62. Thus, the water supplied into the filter device 40 may successively pass through the filter device 40 and then be supplied into the purified water passage 62.
When the filter is separated, and the cap is mounted on the socket 48, the purified water for purifying the passage may pass through the filter device 40 by the water purifying passage 65 without passing through the filter 42.
Also, the user may grasp each of the filters 42. For this, the each of the filters 42 may include a handle that is inclined at a predetermined angle with respect to a vertical line in the state in which each of the filters 42 is mounted on the connector 43.

Also, the water tank 50 may have a cylindrical shape that lengthily extends in a transverse direction. The water tank 50 may have left and right ends that each have a hemispherical shape. For instance, the water tank 50 may include a tank body 51 having a cylindrical shape and a tank cap 52 having a hemispherical shape to cover both opened left and right ends of the tank body 51.
The tank body 51 may be molded in the cylindrical shape with both opened left and right sides by winding the ends of the plate-shaped stainless material to weld and bond ends of the stainless material to each other. Also, both opened left and right ends of the tank body 51 may be bent to form a body flange 511.
The tank cap 52 may be formed of the same stainless material as the tank body 51. The tank cap 52 may have a size and hemispherical shape that are enough to cover both opened left and right sides of the tank body 51. Thus, the water tank 50 may have a pressure container shape so that the water tank 50 is not damaged or broken even though high pressure occurs in the water tank 50. Also, the tank cap 52 may be molded by press processing. A cap flange 521 contacting the body flange 511 may be bent and disposed on a circumference of the tank cap 52.
In the current embodiment, since the tank cap 52 has a hemispherical shape, an angular edge may not exist at the water tank 50 to prevent foreign substances from being caught in the angular edge. Also, since the angular edge does not exist at the water tank 50, cleanability during the cleaning may be improved.
Thus, the body flange 511 and the cap flange 521 may be welded or bonded to each other in a state where the body flange 511 and the cap flange 521 are in contact with each other to couple the tank cap 52 to both sides of the tank body 51.
In the state in which the cap flange 521 and the body flange 511 are coupled to each other, a space may be defined between a portion of the cap flange 511 and an outer surface of the tank cap 52.
Also, the water tank 50 may be disposed in the refrigerating compartment so that a virtual line passing through the pair of tank caps 52 is in parallel with the bottom surface of the refrigerating compartment.
A water inlet tube 522 through which water purified in the filter device 40 is supplied and a water outlet tube 512 through which water stored in the water tank 50 is discharged are provided in the water tank 50.
The water inlet tube 522 may be inserted to pass through a central portion of one tank cap 52 of both side tank caps 52 and may be connected to an outlet of the filter device 40 by the purified water passage 62. Thus, the water purified in the filter device 40 may be introduced into the water tank 50 through the water inlet tube 522.
The water outlet tube 512 may be inserted to pass through the tank body 51 that is adjacent to the tank cap 52 in a direction opposite to that of the water inlet tube 522. The water outlet tube 512 may extend in a vertical direction. The water outlet tube 512 may be disposed away from the water inlet tube 522 to discharge the water through the water outlet tube 512 after the water introduced through the water inlet tube 522 is sufficiently cooled. Also, the water outlet tube 512 is disposed to pass through the top surface of the tank body 51, thereby discharging the water in a state where the water within the water tank 50 is maintained to a full water level state. Then, the water may be sufficiently cooled while the water is supplied into the water tank 50 to reach the full water level state. Also, the water outlet tube 512 may be connected to the cooled water passage 63 to supply the cooled water to the dispenser 20. The water flowing along the purified water passage 62 without passing through the water tank 50 may be supplied into the ice maker 31 or the dispenser 20 in a non-cooled state.
Since the water outlet tube 512 is disposed on a top surface of the tank body 51, bubbles existing within the tank body 51 may be discharged together with water of the tank body 51 through the water outlet tube 512 to prevent an amount of water stored in the tank body 51 from being reduced. That is, since water does not exist in a region in which the bubbles exist in the tank body 51, if bubbles exist, an amount of water stored in the tank body 51 may be reduced. However, according to the current embodiment, since the water outlet tube 512 is disposed on the top surface of the tank body 51, the bubbles 51 may be discharged to the water outlet tube 512 to prevent the storage space of the water from being reduced by the bubbles. Thus, an amount of water to be cooled may be increase.
Also, when the cleaning water is injected through the water inlet tube 522 during the cleaning, a flow direction of the cleaning water within the tank may be changed to allow the cleaning water to be discharged through the water outlet tube 512. Thus, the cleaning water may uniformly clean the inside of the water. As described above, since the angular edge does not exist at the water tank 50, the cleanability of the water tank 50 may be improved.
If the water tank 50 is formed of a plastic material, thermal transfer within the water tank 50 itself may not be smooth, and thus, colder water may be disposed in a lower portion of the water tank 50. However, according to the current embodiment, since the water tank 50 is formed of a stainless material, the thermal transfer between the upper and lower sides of the water tank 50 may be smooth. Thus, even though the water outlet tube 512 is disposed at the upper portion of the water tank 50, water may be sufficiently cooled and then discharged.
The water inlet tube 522 and the water outlet tube 512 may be formed of the same stainless material as the water tank 50. Also, the water inlet tube 522 and the water outlet tube 512 may be respectively coupled to the tank cap 52 and the tank body 51 through welding. Further, the water inlet tube 522 may be connected to an outlet end of a branch tube that is branched from one point of the purified water passage 62 extending to the filter device 40. In addition, the water outlet tube 512 may be connected to an inlet end of the cooled water passage 63 connecting the water tank 50 to the dispenser 20.
A cooled water valve 632 may be provided at a predetermined position of the cooled water passage 63 that is adjacent to the water outlet tube 512. The cooled water valve 632 may be opened or closed by manipulation of the dispenser 20 to determine whether the cooled water is supplied. In a state where the cooled water valve 632 is closed, the inside of the water tank 50 may be maintained in the full water level state.
Referring to
A guide bracket 155 may be provided on an upper portion of the freezing compartment door 14. The guide bracket 155 may be fixedly mounted on a back surface of the outer door 151 at a position corresponding to that of the ice making device 30. Also, an end of the ice making passage 64 extending to the ice making device may be fixed to the guide bracket 155. Further, a receptacle may be provided so that the guide bracket 155 is electrically connected to the ice making device 30. Thus, when the freezing compartment door 14 is molded, the insulation material may be foamed and filled between the outer door 151 and the door liner in a state where the ice making passage 64 and the receptacle are fixed to the guide bracket 155. Then, while the insulation material is foamed, a phenomenon in which the end of the ice making passage 64 and the receptacle are changed in position may not occur. For example, if the outlet end of the ice making passage 64 is changed in position while the insulation material is foamed, it may be difficult to supply water at an accurate position. Also, if the receptacle is changed in position, a connection terminal provided on the ice making device 31 may not be connected to the receptacle.
In some implementations, the dispenser 20 may be provided in the freezing compartment door 14. In these implementations, a dispenser housing 21 constituting the dispenser 20 may be mounted on the outer door 151, and the purified water passage 62 and the cooled water passage 63 are guided to a side of the dispenser housing 21.
As shown, a passage guide 156 may be provided inside the freezing compartment door 14. The passage guide 156 may guide the purified water passage 62 and the cooled water passage 63 which are guided to the side of the dispenser 20. The passage guide 156 may have a tube shape to accommodate the purified water passage 62 and the cooled water passage 63.
The passage guide 156 may extend to a side of the dispenser housing 21 from a side of the lower deco 154 to which a hinge 16 rotatably supporting a lower portion of the freezing compartment door 14 is connected. Here, an opened end of the passage guide 156 may pass through the lower deco 154 to communicate with the outside of the lower deco 154, and the other end of the passage guide 156 may communicate with the dispenser housing 21. Thus, after the freezing compartment door 14 is molded and assembled, the purified water passage 62 connected to a spout of the dispenser 20 may be separated from the cooled water passage 63. Then, the purified water passage 62 and the cooled water passage 63 may be withdrawn to the outside through the lower end of the passage guide 156 and then be treated for necessary service. Also, when the service is finished, the purified water passage 62 and the cooled water passage 63 may be inserted into the passage guide 156 through the lower end of the passage guide 156 and connected to the spout of the dispenser 20. As described above, since the passage guide 156 surrounds the purified water passage 62 and the cooled water passage 63, even though the door-side passage is impacted in the use of the refrigerator, a servicer may easily repair the purified water passage 62 and the cooled water passage 63.
The purified water passage 62 and the cooled water passage 63 which are guided to the dispenser 20 through the end of the passage guide 156 may be connected to the purified water valve 622 and the connection member 662 at a side of the dispenser 20. This will be described below in more detail.

The entire configuration of the dispenser 20 may be determined by the dispenser housing 21. The dispenser housing 21 may form a recessed cavity 211 of the dispenser 20. A water chute 212, an ice chute 213, an input part and push pad 22 for manipulating the dispenser 20, a display part 231 for displaying a state of the dispenser 20, and a display 25 for displaying an operation state of the selection mode as a moving picture or an image. The dispenser 20 or the freezing compartment door may further include an input part that is capable of selecting a sterilization mode for sterilizing the purified water passage and the cooled water passage. Alternatively, the input part for selecting the sterilization mode may be provided on the display 25.
In some examples, the dispenser housing 21 may be manufactured by bonding one or more plastic injection-molded materials. The dispenser housing 21 may be mounted on the outer door 151. Also, the dispenser housing 21 may form the cavity 211 for locating a container, such as a cup, when water is dispensed.
A container tray 29 for supporting the container may be rotatably mounted on a rear surface of the cavity 211. Also, a portion of the dispenser housing 21 defining the rear surface of the cavity 211 may be recessed backward to form a tray seat part 215. The container tray 29 may be seated on the tray seat part 215. A surface of the container tray 29 that is exposed to the outside in a state where the container tray 29 is accommodated in the tray seat part 215 may form a portion of the rear surface of the cavity 211. Here, the container tray 29 may be defined by a front surface that is exposed to the outside in the state where the container tray 29 is seated on the tray seat part 215 and a rear surface on which the container is placed in a state where the rear surface is horizontally rotated. Further, the front surface of the container tray 29 may be flush with the dispenser housing 21 in the state where the container tray 29 is seated on the tray seat part 215. Thus, when viewed from the outside, the container tray 29 may not be easily identified, and may be recognized as a portion of the dispenser housing 21.
Also, the push pad 22 that inputs a command for dispensing water or ice may be provided on the rear surface of the cavity that corresponds to an upper side of the container tray 29. The push pad 22 may manipulate start or stop of the water or ice dispensing. The push pad 22 may be disposed at a center of an upper portion of the cavity 211 so that the push pad 22 is easily pushed by a user in a state where the user grips the cup or container, and at a location where the cup or container easily receives water or ice in the state where the push pad 22 is pushed. That is, centers of the water chute 212, the ice chute 213, and the push pad 22 may be defined on one vertical surface. Also, the one vertical surface may be a vertical surface that equally divides the dispenser 20 in a left/right direction.
The water chute 212 may be disposed at the center of the upper portion of the cavity 211 and coupled to an outlet of a dispensing passage 66 through which purified or cooled water is dispensed. The connection member 662 that will be described below in more detail is connected to the dispensing passage 66. The connection member 662 is disposed from a right side of the dispenser 20 toward a center of the dispenser 20. Here, the dispensing passage 66 may be disposed at a front side of the ice chute 213.
Thus, the dispensing passage 66 may be bent. Also, the dispensing passage 66 may be accommodated into a guide pipe 661 formed of a metal material, such as aluminum, so that the dispensing passage 66 is maintained in its fixed shape. That is, the guide pipe 661 may be bent to extend from the connection member 662 up to the water chute 212. Further, the dispensing passage 66 may pass through the guide pipe 661 and be guided. Accordingly, the dispensing passage 66 may be maintained in position and shape by the guide pipe 661. Thus, increase in resistance within the tube due to the deformation by a water pressure may be prevented and water may be smoothly supplied.
The ice chute 213 and the water chute 212 are disposed in an upper portion of the dispensing housing 21, e.g., at the center of the upper portion of the cavity 211. An electrical component mount part 216 and a valve mount part 217 are disposed on both left and right sides with respect to the water chute 212 and the ice chute 213, respectively.
A detection part, such as a switch, for detecting an operation according to the manipulation of the push pad 22 and/or an operation of a damper for opening or closing the ice chute 213 may be disposed on the electrical component seat part 216 that is disposed at the left side (when viewed in
The electrical component mount part 216 and the valve mount part 217 may be opened forward and covered by the cover plate 23. The cover plate 23 may define a portion of the front appearance of the dispenser 20. The display part 231 for displaying the operation state of the refrigerator may be further disposed on the cover plate 23. In addition, one or more buttons for inputting an operation together with the display part 231 may be further disposed on the cover plate 23.
Thus, when the dispenser 20 is used, the cover plate 23 may be mounted to cover the electrical component mount part 216 and the valve mount part 217. Also, when the refrigerator or the electrical components are assembled, or service for the purified water valve 622, the connection member 662, the purified water passage 62, or the cooled water passage 63 is required, the cover plate 23 may be separated to expose the electrical component mount part 216 and the valve mount part 217.
According to the current embodiment, since the water purified valve 622 is mounted at a position that is adjacent to the dispensing passage 66, when the water purified valve 622 is closed, an amount of water remaining in the dispensing passage 66 may be less, and thus, possibility of water leakage may be reduced, and propagation of bacteria may be suppressed.
Also, even though the water leakage occurs due to the defect of the water purified valve 622, since water is dispensed through the dispensing passage, the contamination within the refrigerator due to the water leakage may be prevented.
A chute cover 24 may be disposed between the electrical component mount part 216 and the valve mount part 217. The chute cover may cover front sides of the water chute 212 and the ice chute 213 to prevent the water chute 212 and the ice chute 213 from being exposed. The chute cover 24 may be disposed at a center of an upper portion of the dispenser 20 to protrude somewhat upward from the cover plate 23. However, the chute cover may be flush with the cover plate 23. Also, the chute cover 24 may be separately provided. Thus, the chute cover 24 may be integrated with the cover plate 23. When the chute cover 24 is integrated with the cover plate 23, the chute cover 24 may be detachably disposed together with the cover plate 23.
The touch screen-type display 25 may be provided on a front surface of the chute cover 24. The display 25 may serve as a plurality of input parts for manipulating an input operation of the dispenser 20. Also, an operation state of the refrigerator 10 or the dispenser 20 may be outputted as an image or moving picture by using the display 25.
Referring to
The purified water passage 62 guided through the passage guide 156 may be connected to an inlet of the purified water valve 622 inside the valve mount part 217. An outlet of the purified water valve 622 may be branched into two parts, and then respectively connected to the purified water passage 62 and the ice making passage 64. Here, the purified water passage 62 connected to an outlet end of the purified water valve 622 may be connected to the connection member 662, and the ice making passage 64 connected to an outlet end of the purified water valve 622 may extend to the ice making device 30. Thus, the purified water supplied through the purified water passage 62 may be switched in passage according to an operation of the purified water valve 622 to flow to the connection member 662 through the purified water passage 62 or flow to the ice making device 30 through the ice making passage 64. When a command for dispensing water through the dispenser 20 and a water supply operation for making ice are performed at the same time, the purified water valve 622 may be fully opened so that the purified water is divided into the connection member 662 and the ice making passage 64 to flow.
The cooled water passage 63 guided through the passage guide 156 is connected to the connection member 662. Also, the purified water passage 62 and the cooled water passage 63 communicate with an inlet of the connection member 662, and the dispensing passage 66 is connected to an outlet of the connection member 662. Thus, the purified water or cooled water supplied through the purified water passage 62 or the cooled water passage 63 may be discharged into one dispensing passage 66 through the connection member 662.
The purified water passage 62, the cooled water passage 63, the dispensing passage 66, the purified water valve 622, and the connection member 662 may be exposed through the valve mount part 217. If service is needed, the components may be connected to each other through a couplable and separable fitting structure so that the components are easily coupled to and separated from each other.

For instance, the operation state of the dispenser 20 or the refrigerator 10 may be displayed in a standby state of the display 25. Also, if the display 25 is not used for a long time, the display 25 may be switched in a power saving mode and thus be turned off.
In this state, when the user touches the display 25 to activate the display 25, a first screen as illustrated in
For example, a purified water input part 251 may be displayed on a left upper end of the display 250 to output a screen for selecting the dispensing of purified water. A cooled water input part 252 may be displayed on a right upper end of the display 250 to output a screen for dispensing cooled water, and a cubed ice input part 253 may be disposed on a left lower end of the display 250 to output a screen for dispensing cubed ice. In addition, a crushed ice input part 254 may be displayed on a right lower end to output a screen for dispensing crushed ice.
Here, the input parts 253 and 254 for selecting a kind of ice, the purified water input part 251, and the cooled water input part 252 may be displayed to be partitioned into a plurality of rows and columns on the display 250.
Thus, the user may touch one of the four input parts, on which desired menus to be dispensed through the dispenser 20 are displayed, to select a kind of water or ice to be dispensed.
For example, when the purified water input part 251 is selected on the first screen, a second screen as illustrated in
As shown in
Here, a dispensing amount input part 225 may be displayed to be partitioned into a plurality of rows and columns on the display 250. Thus, since the dispensing amount input part is displayed on one screen without changing a screen, the user may easily select the dispensing amount.
In addition, as shown in
When the cooled water input part 252, the cubed ice input part 253, or the crushed ice input part 254 are selected on the first screen, or an amount of water to be dispensed through the manipulation of the dispensing amount input parts 255 and 256 is completely set on the second screen, a third screen as illustrated in
That is, when the purified water input part 251 is manipulated to select the purified water on the first screen, and the dispensing amount input parts 255 and 256 are manipulated to select the set amount on the second screen, water supply may automatically start when the second screen is switched into the third screen or may start according to an initial touch of the operation input part 258. When the inputted amount of water is completely dispensed, the water supply may be automatically stopped without performing separate manipulation.
Also, if the user manipulates the operation input part 258 again while the dispensing amount input parts 255 and 256 are manipulated to select the set amount on the second screen, and the water supply is performed according to the initial manipulation of the operation input part 258, the water supply may be stopped even though the water supply amount does not reach the set amount.
In addition, the push pad 22 for dispensing water or ice through the dispenser 20 may be manipulated.
That is, a desired kind of water or ice may be set on the first screen of the display 25 to manipulate the push pad 22, thereby dispensing the water or ice. When the manipulation of the push pad 22 is stopped, the dispensing of the water or ice may be stopped. Here, it may be unnecessary to perform manipulation for separately setting the dispensing amount. Also, when the manipulation of the push pad 22 is detected by a control part, the third screen of
For instance, when the purified water is dispensed, the dispensing amount input parts 255 and 256 are manipulated on the second screen to set an amount of water to be dispensed, the water supply or water supply stopping may be manipulated through the push pad 22. Also, even though the operation input part 258 is manipulated on the third screen to start the dispensing of the water or ice, the water supply may be stopped through the manipulation of the push pad 22.
According to the current embodiment, the cooled water input part, the purified water input part, and the ice kind selection part may be displayed on a first screen, and the dispensing amount input part may not be displayed on the first screen. When the purified water input part is selected, the purified water input part may be displayed on the displayed screen. Thus, when compared to a case in which many input parts are displayed on one screen, the user may easily and instinctively confirm a kind of button. Thus, a time taken to confirm the kind of input part by the user may be reduced, and wrong selection of the input parts may be prevented. In addition, since the screen of the display is displayed in stages, the display may be reduced in size.
A water dispensing process due to the manipulation of the dispenser will be described with reference to
Water supplied from the water supply source 1 may be supplied into the filter device 40 through the water supply passage 61. Here, the water supply into the filter device 40 may be determined by the water supply valve 612 provided in the water supply passage 61. Also, a flow sensor 613 may be provided on the water supply passage 61 to detect a flow rate. Thus, when the dispenser 20 is manipulated, a set amount of water may be dispensed by using the flow rate detected by the flow sensor 613. The flow sensor 613 may measure a flow rate of water passing through the water supply passage 61. The flow sensor 613 may include a magnetic type flow sensor and a hall type flow sensor.
Water introduced into the filter device 40 may be purified by the filter 42. The water purified by the filter device 40 may flow along the purified water passage 62 to pass through the hinge 16, thereby being supplied into the dispenser 20. Also, the purified water valve 622 may be provided in the dispenser 20. The purified water passage 62 and the ice making passage 64 may be branched from the purified water valve 622. The branched purified water passage 62 may extend to the connection member 662 of the dispenser 20, and the ice making passage 64 may extend to the ice making device 30. That is, the purified water valve 622 may operate according to a user's manipulation to adjust the supply of purified water into the dispenser 20 or the ice making device 30.
The cooled water passage 63 may be branched from one point of the purified water passage 62 extending from the outlet end of the filter device 40. The cooled water passage 63 may pass through the hinge 16 to extend to the dispenser 20. The water tank 50 and the cooled water valve 632 are provided on the cooled water passage 63. Thus, the purified water passing through the filter device 40 may be introduced into the water tank 50 through the cooled water passage 63 and then cooled and stored. When the cooled water valve 632 is opened, the cooled water may be supplied into the dispenser 20.
The purified water passage 62 and the cooled water passage 63 which are disposed on a side of the dispenser 20 may be connected to the connection member 662, and thus, water may be dispensed into the dispenser 20 through the dispensing passage 66 provided in the connection member 662.
In the refrigerator having the above-described passage structure, when the user manipulates the cooled water input part 252 of the display 25 so as to dispense cooled water, the dispensing of the cooled water occurs. When the operation input part 258 of the display 25 is manipulated, or the push pad 22 is pushed, the cooled water valve 632 may be opened to dispense the cooled water from the water chute 212 of the dispensing passage 66. When the user manipulates the operation input part 258 again, or a hand or container pushing the push pad 22 is detached from the push pad 22 after the desired amount of water is dispensed, the water supply may be stopped.
Also, when the user manipulates the purified water input part 251 of the display 25 so as to dispense the purified water, the purified water valve 622 may be switched so that the water dispensing through the purified water passage 62 occurs. In this state, the water supplied from the water supply source 1 may be purified by passing through the filter device 40. Then, the purified water may be directly dispensed into the dispenser 20 through the purified water passage 62.
For instance, the user may set an amount of water to be dispensed through dispensing amount input parts 255 and 256 of the display 25. That is, when the user manipulates the dispensing amount input parts 255 and 256 to input an amount of water to be dispensed, and then, operates the operation input part 258 or the push pad 22, the purified water may be dispensed through the dispensing passage 66 communicating with the cooled water passage 63.
Also, when the purified water is dispensed, the flow sensor 613 may detect a flow rate of water supplied from the water supply source 1. Thus, the water supply stopping may be determined according to the flow rate detected by the flow sensor 613. That is, when the dispensing of the preset amount of water is detected by the flow sensor 613, the purified water valve 622 may be closed without a separate manipulation to complete the dispensing of the purified water.
For example, when the purified water is selected by using the purified water input part, the purified water valve may be opened, and the cooled water valve may be closed. In this state, when the preset amount of water is dispensed by using the dispensing amount input part, the purified water valve is closed. On the other hand, when the cooled water is selected through the cooled water input part, the cooled water valve may be opened, and the purified water valve may be closed. Here, whether the preset amount of water is dispensed by using the dispensing amount input part may be determined on the basis of the flow rate detected by the flow sensor 613.
When a predetermined amount of purified water is dispensed in a state where the pushing of the push pad 22 is detected, if the pushing operation of the push pad 22 is not released until the predetermined amount of purified water is dispensed, the purified water valve 612 may be closed so as to stop the dispensing of the purified water. That is, when a predetermined amount of purified water is dispensed in a state where the pushing of the push pad 22 is detected, the purified water valve may be closed to stop the dispensing of the purified water, regardless of whether the release of the pushing of the push pad 22 is detected. Also, after a predetermined amount of purified water is dispensed, the purified water valve may be closed even though the pushing of the push pad 22 is continuously detected.
If the release of the pushing of the push pad 22 is detected before the predetermined amount of purified water is dispensed, the purified water valve 612 may be immediately closed.
When the cubed ice input part 253 or the crushed ice input part 254 of the display 25 is manipulated, corresponding ice may be dispensed through the ice chute 213 of the dispenser 20.

In some implementations, the sterilization device 70 may generate hypochlorous acid (HOCl) by electrolyzing supplied water to form cleaning water that serves as sterilizing water. Also, the sterilization device 70 may have a portable structure and thus be connected to the water supply passage of the refrigerator.
The sterilization device 70 is installed on the water supply passage 61 connecting the water supply source 1 to the filter device 40. In this state, water supplied through the water supply source 1 may pass through the sterilization device 70 and then be supplied into the refrigerator 10.
Then, the filter 42 mounted on a socket 48 of the filter device 40 is separated by the user. Here, a blocking member for blocking a passage connected to the filter 42 may be provided in the socket 48. If the blocking member is not provided, a separate filter cap may be mounted to prevent water from leaking from the socket 48 when the filter 42 is separated.
Then, the sterilization device 70 may operate to allow the sterilizing water generated by the sterilization device 70 to flow along the water supply passage 60. The sterilizing water may be successively filled into the water purifying passage 65 of the filter device 40 from which the filter 42 is removed, the water tank 50, the purified water passage 62, the cooled water passage 63, and the ice making passage 64. Here, a portion of the water purifying passage 65 from an outlet end of the sterilization device 70, e.g., the water purifying passage except for the passage passing through the filter 42, may be defined as a sterilization passage.
When the sterilization device 70 operates, the ice making device 30 enters into a test mode. In the test mode, the tray of the automatic ice maker 31 may be empty, and the sterilizing water supplied through the ice making passage 64 may be supplied into the tray of the automatic ice maker 31 to sterilize the ice making passage 64 and the tray of the ice making device 30 by using the sterilizing water.
Also, the sterilizing water filled into the water supply passage 60 and the water tank 50 may stay in the water supply passage 60 and the water tank 50 for a preset time to sterilize inner walls of the water supply passage 60 and water tank 50. After the sterilization is completed for the preset time, the push pad 22 of the dispenser 20 or the operation input part 258 may operate to drain the sterilizing water in the water supply passage 60.
After the sterilizing water is completely drained through the dispenser 20, the sterilization device 70 may be separated from the water supply passage 61. Then, the blocking member or cap mounted on the socket 48 may be removed, and the filter 42 may be mounted again on the socket 48, thereby completing the sterilization process.
Also, a process for emptying ice stored in the ice bank 32 may be required so that the ice made in the test mode is not supplied into the ice bank 32. Also, this process may be informed to the display part 231 or the display 25 of the refrigerator 10. Alternatively, the ice bank 32 may be empty after the sterilization process starts, and then, ice generated during the sterilization process and stored in the ice bank may be completely empty.

In addition, a driving unit for providing a rotation force to the tray 29 may be provided on the rotation shaft 291. The driving unit may have a structure that provides a rotation force for automatically rotating the container tray 29 to a horizontal state when the front surface of the container tray 29 is pushed and then released. For example, a driving unit that is adapted for an automatically openable cassette deck may be used as the driving unit. In some implementations, if the latch part 293 is pushed and then released, a predetermined repulsive force may occur. Thus, the container tray 29 may rotate forward by the repulsive force. A deceleration mechanism may be provided on the rotation shaft 291 to rotate the container tray 29 at a low speed.
Referring to
In detail, a gripping groove 292 to be gripped by a user's fingers may be defined in an upper end of the container tray 29. When it is intended that the container tray 29 rotates, the user rotates the container tray 29 forward in a state where the user grips the gripping groove 292. Thus, the container tray 29 may rotate forward with respect to the rotation shaft 291. In this structure, it may be unnecessary to provide a separate latch structure on the rear surface of the container tray 29 and a separate deceleration mechanism on the rotation shaft 291.
Referring to
In some implementations, to dispense a large amount of water or ice, it may be difficult to utilize the push pad 22. If it is difficult to push the push pad 22 because a container has a volume greater than that of a cavity 211 of the dispenser 20, or a container tray 29 horizontally rotates forward to support the container, it may be unnecessary to utilize the push pad 22. Here, a display 25 (see
In some implementations, the user may manipulate the input unit provided on the display 25 or the cover plate 23 so as to dispense a small amount of water or ice. Then, the user may select an object to be dispensed and push the push pad 22 to dispense the desired object to be dispensed, e.g., one of water or ice. However, to dispense a large amount of water or ice, in a state where the container tray 29 rotates forward, a dispensing object selection button provided on the display 25 of the chute cover 24 or cover plate 23 is pushed to select a desired object to be dispensed. Then, a dispensing amount of selected object may be selected to push the dispensing button.
A tray seat part 215 in which the container tray 29 is accommodated is disposed on a rear surface of the cavity 211 defined in the dispenser 20. Furthermore, a container accommodation groove 218 that is further recessed by a predetermined depth from the inside of the tray seat part 215 may be further defined. The container accommodation groove 218 enables the container to be pushed further into the cavity 211 in the state where the container tray 29 rotates forward. The container accommodation groove 218 may be equally applied to the other examples described throughout this disclosure.
Also, a push pad seat groove 294 on which the push pad 22 is seated may be defined in an upper portion of a front surface of the container tray 29. In addition, a front surface of the push pad 22 may further protrude from the front surface of the container tray 29.
Referring to
Also, since the push pad 22 integrally rotates with the container tray 29, it is unnecessary to apply a pressing pressure to the push pad 22 in the state where the container tray 29 rotates. Thus, the push pad 22 may be disposed on a position at which the push pad does not interfere with the bottom surface of the cavity including a residual water cover 26 in the state where the container tray 29 rotates in the horizontal direction. For this, the push pad 22 may be disposed on the front surface of the container tray 29 corresponding to an area that protrudes from a front surface of a door 14. Thus, the push pad 22 may be disposed at a point that is close to an upper end of the container tray 29.
Referring to
When the push pad 22 is pushed, an input signal generation part 80 for recognizing the pushing operation as a dispensing command input of water or ice is used. Hereinafter, a structure of the input signal generation part 80 will be described.
The input signal generation part 80 may be provided on the push pad 22 and the container tray 29 through various methods. For example, the input signal generation part 80 may include a magnet 82 provided on one side of the push pad 22 and the container tray 29 and a hall sensor 81 provided on the other side. The magnet 82 may be disposed on an upper end of the push pad 22, and the hall sensor 81 may be provided on an upper end of the push pad seat groove 294, and vice versa.
With this structure, in a state where the dispensing command is not inputted, the magnet 82 is maintained in a state where the magnet is spaced apart from the hall sensor 81. Thus, the magnet 82 is not detected by the hall sensor 81. When the push pad 22 is pushed to input the dispensing command, the magnet 82 may move directly downward from the hall sensor 81. As a result, the hall sensor 81 may detect a magnetic force generated in the magnet 82 to generate a pulse. The generated pulse may be transmitted into the control panel through a signal line. While a pulse on state is maintained, water or ice may be dispensed. When a force pushing the push pad 22 is released, a pulse off state may be output to stop the dispensing operation.
Referring to
The input signal generation part 83 having the on/off switch may be provided on a back surface of a push pad 22 and a seat surface of a push pad seat part 294.
In detail, when the push pad 22 for inputting the dispensing command of water or ice is pushed, a contact part disposed on the back surface of the push pad 22 and a contact part disposed on the push pad seat part 294 may be connected to each other to turn a switch on. While the switch on state is maintained, water or ice may be dispensed. When a switch off state occurs, the dispensing operation may be stopped.
Referring to
In detail, the push pad 22 is mounted and fixed on a front surface of the container tray 29. When the push pad 22 is pushed, the container tray 29 is pushed backward. Then, a magnet 82 mounted on the container tray 29 moves backward, and thus, a hall sensor 81 detects the magnet 82. As a result, a pulse signal is generated from the hall sensor 81.
