The present disclosure relates to the technical field of kitchen appliances, and more particularly, to a dish washer.
With improvements in the lives of people, the demand for dish washers has been greatly increased, and people also make higher requirements for the dish washers. A dish washer is usually provided with a plurality of spraying devices in a washing tank. Due to the different numbers of dishes to be washed each time, not all the spraying devices should be used at the same time when the dishwasher is used each time. However, there is no product that can control respective spraying devices at different locations to be opened or closed, which is not beneficial to water conservation when people use the dish washer. In addition, most of the existing dish washers only have one washing area, which results in that the existing dishwashers cannot perform cleaning with different intensities at different washing areas at the same time.

As shown in
As shown in
For example, the plurality of spraying ducts 20 are arranged along a length direction of the washing tank 11, or along a width direction of the washing tank 11. A length direction of the plurality of spraying ducts 20 may be the same as the width direction of the washing tank 11 (i.e., in an arrangement along the length direction of the washing tank 11), or may be the same as the length direction of the washing tank 11 (i.e., in an arrangement along the width direction of the washing tank 11). Each spraying duct 20 has the spraying holes, and the plurality of spraying ducts 20 are arranged and mounted in the washing tank 11. The spraying holes are arranged in the same straight line or offset in different straight lines, along the length direction of the spraying duct 20.
A water supply system 40 allows a water supply to be in communication with a water inflow end of the spraying ducts 20, such that the water supply system provides water into the spraying ducts 200.
As shown in
In some embodiments, as shown in
A detachable structure for the partition plate 60 is described in detail now. In this embodiment, an inner wall of the container 10 is provided with a groove extending along an up-down direction of the container 10, the partition plate 60 is mounted in the groove in a drawable mode. As an optimal implementation, an upper portion of the partition plate 60 is provided with a grip recess, such that the partition plate 60 can be easily held and pulled.
Furthermore, referring to
Furthermore, the water supply system 40 is described now. As shown in
The cup assembly 404 is arranged at the bottom of the washing tank 11, and has a first end in communication with the washing tank 11 and a second end in communication with a water inlet opening of the water pump 402. For example, the cup assembly 404 is arranged at the bottom of the washing tank 11 and connected to a water discharge port at the bottom of the washing tank 11, and water in the washing tank 11 can flow out through the cup assembly 404.
The water softener 401, the cup assembly 404, the water pump 402, and the water supply duct 403 are sequentially connected to one another. The water softener 401 is in communication with an external water supply source, the water supply duct 403 is in communication with the spraying ducts 20, external water supply enters and is softened by the water softener 401, and is subsequently stored in the cup assembly 404. The water pump 402 drives water in the washing tank 11 to flow from the cup assembly 404 into the spraying ducts 20 through the water supply duct 403, and subsequently the water is sprayed into the washing tank 11 through the spraying holes on the spraying ducts 20.
In some embodiments, as shown in
In this embodiment, under action of the water pump 402, water enters the pressure-maintaining duct 50 through the water outlet opening of the water pump 402, and enters the spraying ducts 20 after passing through the pressure-maintaining duct 50. The water for washing is received in the pressure-maintaining duct 50 firstly, water pressure in the pressure-maintaining duct 50 can be maintained due to direct fluid communication between the pressure-maintaining duct 50 and the water pump 402 (without other element provided therebetween). A distance between the water of high pressure and the spraying duct 20 is very small after transportation through the pressure-maintaining duct 50, loss of water pressure due to transportation of water in a pipeline is greatly reduced. In the related art, the water pump and the spraying ducts are connected through water pipes respectively, and water in the different spraying ducts travels different distances. In contrast, in the present disclosure, water entering the spraying ducts 20 travels an equivalent distance. Therefore, in the present disclosure, the effect, that water entering the spraying ducts from different paths has different pressures due to different journeys in transportation, can be prevented. Furthermore, water entering the plurality of spraying ducts 20 has an equivalent pressure because of the pressure-maintaining duct 50. As a result, the plurality of spraying ducts 20 work at an equivalent efficiency, washing effect of the washing system is more uniform, and the undesirable effect that some spraying ducts 20 are poor at spraying and washing since they are arranged at a distance too far away the water pump 402 can be prevented. With the pressure-maintaining duct 50, not only the uniformity of the washing system is improved, but also the spraying and washing efficiency of the spraying duct 20 is guaranteed, thereby improving washing performance of the washing system.
In some embodiments, in order to improve the compactness of structure and utility rate of space, the pressure-maintaining duct 50 and the water pump 402 are both arranged at the bottom of the washing tank 11. Furthermore, the water pump 402 is arranged adjacently to a side wall of the washing tank 11, the pressure-maintaining duct 50 is arranged adjacently to a middle portion of the bottom of the washing tank 11, and an offset distance is provided between the water inflow end 51 of the pressure-maintaining duct 50 and the water outlet opening of the water pump 402. The water pump 402 is arranged directly under the washing tank 11 and located at an end of the washing tank 11. Meanwhile, in order to make a water outflow end 52 of the pressure-maintaining duct 50 more adjacent to the water intake of the spraying duct 20, the pressure-maintaining duct 50 is arranged adjacently to the middle portion of the bottom of the washing tank 11. By arranging the offset distance between the water inflow end 51 of the pressure-maintaining duct 50 and the water outlet opening of the water pump 402, mounting requirements for the water pump 402 and the pressure-maintaining duct 50 can be both taken into consideration. In some embodiments, in order to utilize space more sufficiently and reasonably, the bottom of the washing tank 11 is also provided with a water path structure, such as the cup assembly 404, the water softener 401, etc. The water softener 401 and the water pump 402 are diagonally arranged, and the water pump 402 assembly is located between the water pump 402 and the water softener 401.
In some embodiments, in order to counter reduction of water pressure from the water pump 402 to the pressure-maintaining duct 50, an axis of the pressure-maintaining duct 50 is parallel with an axis of the water outlet opening of the water pump 402. That means a length direction of the pressure-maintaining duct 50 is in line with a water output direction of the water outlet opening of the water pump 402 (in which a certain included angle is allowable, such as 5 degrees), such that water flows out of the water pump 402 in a direction the same as a flowing direction in the pressure-maintaining duct 50, which minimizes the loss of water pressure. In order to meet both of position requirements of the water pump 402 and the pressure-maintaining duct 50, an offset distance d is provided between the axis of the pressure-maintaining duct 50 and the axis of the water outlet opening of the water pump 402. The pressure-maintaining duct 50 and the water outlet opening of the water pump 402 are in parallel but not collinear. The offset distance d can be set according to actual conditions, such as the offset distance ranges from 1 mm to 200 mm, for example ranges from 5 mm to 30 mm.
A length of the pressure-maintaining duct 50 ranges from 60 mm to 80 mm, and a radial dimension of the pressure-maintaining duct 50 ranges from 20 mm to 30 mm. The length of the pressure-maintaining duct 50 should not be too long, which otherwise affects the layout of other parts. The length of the pressure-maintaining duct 50 should not be too short, which otherwise affects pressure maintaining. A diameter of the pressure-maintaining duct 50 should not be too large, which otherwise makes it difficult to mount, occupies too much space, and is adverse to reasonable layout. The diameter of the pressure-maintaining duct 50 should not be too small, which otherwise cannot guarantee a volume of the pressure-maintaining duct 50 and then affects pressure maintaining thereof.
In order to facilitate offset arrangement of the pressure-maintaining duct 50 and the water pump 402, the water inflow end 51 of the pressure-maintaining duct 50 is provided with an inlet port 53, and the inlet port 53 is offset towards the water pump 402. The inlet port 53 is less than the diameter of the pressure-maintaining duct 50 and provided at a side of the pressure-maintaining duct 50 adjacent to the water pump 402. In such an arrangement, an inclined angle (an angle included between a water pipe and the pressure-maintaining duct 50) of the water pipe connecting the pressure-maintaining duct 50 to the water pump 402 is reduced, which further facilitates flowing of water and reduces reduction of the water pressure.
In some embodiments, in order to make connection between the pressure-maintaining duct 50 and the water pump 402 more flexible and convenient, the inlet port 53 and the water outlet opening of the water pump 402 are connected through a hose 54. The hose may be in many forms, such as a plastic hose, for example a rubber hose. Another end of the pressure-maintaining duct 5 is provided with a cap, and the cap is provided with a flexible water pipe in communication with the spraying duct. There are many ways to realize connection between the cap and the pressure-maintaining duct 50, such as screw connection, snapping connection, adhering connection, direct tight-fit snapping connection.
In some embodiments, in order to improve stability of mounting the pressure-maintaining duct 50 and reduce steps for mounting the pressure-maintaining duct 50 and vibration of the pressure-maintaining duct 50, the pressure-maintaining duct 50 and the cup assembly 404 are integrally formed. Since the pressure-maintaining duct 50 and the cup assembly 404 are integrally formed by injection molding, the vibration of the pressure-maintaining duct 50 during operation needs to overcome loads on the cup assembly 404, such that the pressure-maintaining duct 50 is not easy vibrate due to the large loads on the cup assembly 404. Failure of mounting due to the vibration can be avoided, and the stability of mounting the pressure-maintaining duct 50 can be improved and noises can be effectively reduced.
In other embodiments, a detachable connection is provided between the pressure-maintaining duct 50 and the cup assembly 404. A bottom of the cup assembly 404 is provided with a snapping structure with a snapping groove, and the pressure-maintaining duct 50 is snapped into the snapping groove. Since the detachable connection is provided between the pressure-maintaining duct 50 and the cup assembly 404, the pressure-maintaining duct 50 can be conveniently maintained and replaced. The snapping groove is in a shape of an arc and abuts an outer side wall of the pressure-maintaining duct 50 by a large margin, such that the pressure-maintaining duct 50 is effectively fixed to the cup assembly 404.
In some embodiments, in order to save cost, under the condition of ensuring cleaning efficiency of each spraying duct, the water supply system is used as little as possible. For example, one water pump 402 supplies water to the plurality of spraying ducts 20, that is, the water supply system 40 supplies water to all the plurality of spraying ducts 20. In order to achieve individual control, one water supply system 40 needs to cooperate with diverter parts, such as a diverter valve 80. In other embodiments, in order to individually control different spraying ducts and further increase impact force of water output from the spraying duct, a plurality of water supply systems are provided, for example, two water supply systems supply water to four spraying ducts.
An example is described in detail hereafter, in which one water supply system supplies water to all the plurality of spraying ducts through a structure, such as the diverter valve 80 and the like, and individual control is achieved, as shown in
The dish washer has one water supply system 40, which means that the dish washer has only one water pump 402. In order to achieve individual control, the dish washer further includes the diverter valve 80.
A water inlet end of the diverter valve 80 is in communication with the water outlet opening of the water pump 402, the diverter valve 80 includes a plurality of water output parts, and the water output parts are in communication with the spraying ducts 20, such that the diverter valve 80 is used to control water supplying to the spraying ducts 20 by controlling (throttling or allowing) the water flow through the water output parts. The diverter valve 80 may be in various forms, as along as the water supply can be divided into branches of water, and each of the branches of water can be individually controlled. For example, the diverter valve 80 is a one-way-in and two-way-out valve, the diverter valve 80 has three positions which respectively correspond to a state in which a first water output part is opened, a state in which a second water output part is opened, and a state in which both the first water output part and the second water output part are opened. Taking a ball valve for example, when a first water output valve is opened, the ball valve blocks the second water output part; when a second water output valve is opened, the ball valve blocks the first water output part; and when both of the first water output valve and the second water output valve are opened, the ball valve is located at a third position.
In this embodiment, with the diverter valve 80, water supplied from the water pump 402 needs to be divided by the diverter valve 80 and then enters each of the spraying ducts 20. When the water passes through the diverter valve 80, the diverter valve 80 divides the water into branches of water, and the branches of water enter the spraying ducts 20 through the plurality of water output parts respectively. The diverter valve 80 can individually control each of the branches of water or each group of branches of water, by controlling opening and closing of each of the water output parts or each group of the water output parts (the water output parts are divided into groups), which makes it more convenient for users to use the spraying ducts 20 based on their own needs, thereby avoiding waste of water and significantly increasing the efficiency of water.
It is worth noting that, the same dish washer can have different cleaning areas by individually controlling the branches of water or groups of branches of water. When a power of the water pump is adjusted, different cleaning intensities can be achieved at different cleaning areas or the same cleaning area, such as a powerful cleaning area and a gentle cleaning area, therefore the users can perform desirable cleaning intensity at different cleaning areas based on their needs.
In some embodiments, in order to provide better water distribution and control, the dish washer further includes the diverter 90. The diverter 90 has a water inlet 91, a water outlet 92, and a water-diverting chamber 93 in communication with the water inlet 91 and the water outlet 92. The water inlet 91 is in communication with the water output parts, the water outlet 92 is in communication with the spraying ducts 20. The diverter 90 is arranged downstream of the diverter valve 80 and cooperates with the diverter valve 80, water flow after division by the diverter valve 80 is in communication with the water inlet 91 of the diverter 90. It is noteworthy that, one diverter 90 can have only one water inlet 91, or can have a plurality of water inlets 91. Correspondingly, there may be a plurality of types of communications between the water output parts and the water inlet 91. For example, each of the water output parts corresponds to one water inlet 91, or each of the water output parts corresponds to a plurality of water inlets 91. For example, the number of the water output part(s) corresponds to that of the water inlet(s) 91. Regarding correspondence between the water outlet 92 and the water inlet 91, one water inlet 91 can correspond to one water outlet 92, or one water inlet 91 can correspond to a plurality of water outlets 92, for example, one water inlet 91 and correspond to the plurality water outlets 92. A completed example is described as follows, in which one water output part corresponds to one water inlet 91 and a plurality of water outlets 92. Opening and closing of the one water inlet 91 and the plurality of water outlet 92 can be controlled by controlling opening and closing of the one water output part. With the diverter 90, the number of branches of water can be further increased, which enables the diverter valve 80 to control more spraying ducts 20; and the number of the controlled spraying ducts 20 can be adjusted by adjusting the number of the water outlets 92 corresponding to each of the water inlets 91.
In order to provide better water distribution, a plurality of water-diverting chambers 93 are provided, and the plurality of the water-diverting chambers 93 are spaced apart from each other. One water-diverting chamber 93 corresponds to one water inlet 91 and the plurality of water outlets 92. Water enters the water-diverting chamber 93 through the one water inlet 91 and leaves through the plurality of water outlets 92. The plurality of spaced part water-diverting chambers 93 are divided from one big cavity. For example, two water-diverting chambers 93 are provided, and the two water-diverting chambers 93 can have two water inlets 91 independent from each other, or the same one water inlet 91 is divided into two parts separated from each other, in this case, the two separated parts form two adjacent water inlets 91. Water mixing between adjacent water-diverting chambers 93 can be prevented by mutually separating the water-diverting chambers 93 from each other completely.
It is noteworthy that, the diverter 90 can be arranged at a plurality of positions, such as two ends and a front side of the washing tank 11, and the like. In this embodiment, for example, the diverter 90 is arranged at the bottom of the washing tank 11 and adjacent to an end of the water intake of the spraying duct 20. For example, the diverter 90 is arranged at the bottom of the washing tank 11 of the dish washer, and the diverter 90 is located at a position adjacent to the water intake of the spraying duct 20, and the water outlet is towards the water intake. Since the diverter 90 is adjacent to the inlet of the spraying duct 20 and the water outlet 92 of the diverter 90 is towards the water intake of the spraying duct 20, such that water flows smoothly from the diverter 90 to the spraying duct at a shorter distance, and this can help to reduce energy loss of water flow in the process, raise a water pressure of water flow entering the spraying duct, and raise cleaning efficiency of the dish washer.
A function of the diverter 90 is described hereinafter through an example.
The diverter 90 includes a housing 97, a water inlet 91 located at a side of the housing 97, a water-inlet pipe 94 arranged at the water inlet 91, a water-outlet pipe 95 arranged at a water outlet 92.
For example, the housing 97 has an overall rectangular appearance and is hollow inside. The water-inlet pipe 94 is mounted to the water inlet 91, such that water divided by the diverter valve 80 can enter the water-diverting chamber 93 of the housing 97 through the water-inlet pipe 94. The water-outlet pipe 95 is arranged at the water outlet 92, a plurality of water-outlet pipes 95 are arranged along a length direction of the housing 97. The water-inlet pipe 94 has a diameter larger than a diameter of the water-outlet pipes 95. In this case, one water-inlet pipe 94 corresponds to one water output part of the diverter valve 80. When the diverter 90 has a plurality of water inlets 91, one diverter 90 corresponds to the plurality of water output parts, or one water-inlet pipe 94 corresponds to the plurality water output parts (referring to embodiments as follows).
In order to improve utility rate of space, one diverter 90 is divided into a plurality of water diversion systems by a water separation plate. The diverter 90 further includes a chamber-partition board 96, and the chamber-partition board 96 extends from a bottom of the housing 97 into the water-inlet pipe 94 to form a plurality of water-diverting chambers 93 separated from each other. The chamber-partition board 96 extends from the water-inlet pipe 94 to a bottom of an outer frame to completely partition the water-inlet pipe 94 and an inner chamber of the housing into a plurality of independent parts. In this case, one water-inlet pipe 94 corresponds to a plurality of water feeding systems, and one water inlet 91 also can be divided into a plurality parts correspondingly. The number can be set based on practical needs, for example, the number can be two, i.e., both of the water-inlet pipe 94 and the chamber of the housing 97 are divided into two part independent from each other. In this case, for example, the number of the water-outlet pipes 95 corresponding to each of the water-diverting chambers 93 is two.
It is noteworthy that, the water-inlet pipe 94, the housing 97 and the water-outlet pipe 95 can be integrally formed. The water-inlet pipe 94 can be connected to the diverter valve 80 by a water pipe, or the water-inlet pipe 94 is connected to the diverter valve 80 directly. A plurality of types of connection can be provided, such as snapping connection, screw connection, or flanged connection, etc.
In some other embodiments, in order to further improve control of the water supply system, the diverter 90 can control water supply to each water-diverting chamber 93. For example, the diverter 90 also includes an interception plate (not shown). The interception plate is movably connected to the water-inlet pipe 94 to close or open an area defined by the chamber-partition board 96 and an inner wall of the water-inlet pipe 94. The interception plate cooperates with the water-inlet pipe 94, and the interception plate has three functional positions. A first position is located at a side of the water-inlet pipe 94 to close one water-diverting chamber 93. A second position is located at another side of the water-inlet pipe 94 to close another one water-diverting chamber 93. A third position is in a put-away state or disconnected state, and two inlets of the water-inlet pipe 94 are both in communication. With the interception plate, the diverter 90 can independently control water supply to each of the water-diverting chambers 93.
There may be a plurality of types of connection, which can be provided between the spraying duct 20 and the water-outlet pipe 95. For example, the spraying duct is connected to the water-outlet pipe 95 directly or by a hose, such as a short hose.
In some embodiments, a powerful cleaning area, a gentle cleaning area, and a moderate cleaning area and the like can be formed by cooperation between the three position of the interception plate and a power of the water pump. An example is described hereinafter. When the interception plate is located at the first position, an area which is not closed is the powerful cleaning area, and the power of the water pump is increased. When the interception plate is located at the second position, an area which is not closed is the gentle cleaning area, and the power of the water pump is decreased. When the interception plate is located at the third position, the two cleaning areas are both the moderate cleaning areas, and the power of the water pump is between the power for powerful cleaning and the power for gentle cleaning.
In the embodiment with the diverter valve 80, the pressure-maintaining duct 50 can be arranged at a water path between the water pump 402 and the diverter valve 80, or the pressure-maintaining duct 50 is arranged at a water path between the diverter valve 80 and the diverter 90. It is noteworthy that, in this embodiment, arrangement of the pressure-maintaining duct 50 needs to guarantee independent control to the water supply system. When the pressure-maintaining duct 50 is located at a water path between the water pump 402 and the diverter valve 80, the water inflow end 51 of the pressure-maintaining duct 50 is in communication with the water pump 402, and the water outflow end 52 is in communication with the inlet of the diverter valve 80. When the pressure-maintaining duct 50 is located between the diverter valve 80 and the diverter 90, it is needed to provide a plurality of flow passages to the pressure-maintaining duct 50 to guarantee correspondence between the water output parts of the diverter valve 80 and the water inlet 91 of the diverter 90. For example, one of the water output parts corresponds to one of the flow passages of the pressure-maintaining duct 50, and a first water inlet 91.
An embodiment is described hereinafter, and a plurality of water supply systems can be individually controlled.
Referring to
Since the dish washer provided by the present disclosure is provided with the plurality of water supply systems, cleaning can be performed in different cleaning areas at the same time without a diverter valve. Moreover, since different cleaning areas are in communication with different water supply systems which are independent from each other, the different water supply systems can be provided with different cleaning intensities, cleaning of different intensities can be performed in different cleaning areas at the same time, such that tableware of different dirty degrees can be cleaned differently, and water can be saved on the premise that the tableware can be cleaned satisfactorily.
For example, two cleaning areas and two the water supply systems can be provided. A first water supply system can be provided with a high water pressure, and a second water supply system can be provided with a normal water pressure, so as to perform different cleaning in different areas. For example, when the first water supply system is started and the second water supply system is stopped, powerful cleaning can be performed. When the first water supply system is stopped and the second water supply system is started, normal cleaning can be performed. When the first water supply system and the water supply system are both started, both of the powerful cleaning and the normal cleaning can be performed at the same time.
A design of the present disclosure is not limited thereto. In other embodiments, three, four, or more cleaning areas can be provided, and each of the cleaning area is provided with one water supply system, such that different water supply systems are configured to perform cleaning of different intensities, thereby achieving various cleaning effects.
Furthermore, as shown in
Since a spraying arm is replaced with the spraying duct 20 in the dish washer provided by the present disclosure, the spraying duct 20 rotates about the axis to change a spraying angle, thereby changing a cleaning range, such that at least two kinds of beneficial effects can be achieved as follows. Firstly, the spraying duct 20 is small in size and occupies a small space, such that the sink dish washer can have a larger containing space. In addition, since the spraying duct 20 rotates about its own axis, the spraying duct 20 occupies a space that is equal to its actual volume, such that it is can be ensured that the sink of the dish washer have a larger containing space. Secondly, since the spraying duct 20 is controlled by the driving device 30, a rotation angle of the spraying duct 20 can be accurately controlled, a cleaning angle and range of the spraying duct 20 can be accurately controlled, such that a dead area during cleaning can be prevented and the tableware can be thoroughly cleaned.
In an embodiment of the present disclosure, as shown in
The first cleaning area can be configured as a normal cleaning area, and the second cleaning area can be configured as a powerful cleaning area. The water supply system 40 is configured as a dual-water path system, and the first water supply system 41 and the second water supply system 42 of the dual-water path system are provided with different intensities, such that powerful cleaning and gentle cleaning can be performed at different areas during a single cleaning, and the user can clean tableware of different dirty degrees differently.
In addition, the tableware can be cleaned with different degrees when passing through cleaning areas of different intensities in sequence. For example, the tableware to be cleaned can enter the powerful cleaning area firstly to be cleaned for flushing away food debris, and subsequently the tableware enters the normal cleaning area to be cleaned for thoroughly cleaning oil dirt.
The design of the present disclosure is not limited to the above-described embodiments. In other embodiments, the first washing tank 111 can also be in communication with the second washing tank 112, such that the tableware can be conveniently transferred from the powerful cleaning area to the normal cleaning area.
Furthermore, referring to
A detachable structure for the partition plate 60 is described in detail now. In this embodiment, an inner wall of the container 10 is provided with a groove extending along an up-down direction, the partition plate 60 is mounted in the groove in a drawable mode. As an optimal implementation, an upper portion of the partition plate 60 is provided with a grip recess, such that the partition plate 60 can be easily held and pulled.
Furthermore, referring to
As an exemplary embodiment, a top of the sealing wall 70 is provided with a groove, the bottom of the partition plate 60 is fittingly embedded in the groove. The sealing performance of the partition plate 60 can be further improved, and strength of a connection between the partition plate 60 and the container 10 can be improved.
Furthermore, a structure for mounting the water supply system is described. In this embodiment, the partition plate 60 is arranged at a middle portion of the container 10, and the first water supply system 41 is arranged at an outer wall surface of a bottom of the first washing tank 111. The second water supply system 42 is arranged at an outer wall surface of a bottom wall of the second washing tank 112, and the first water supply system 41 and the second water supply system 42 are symmetrically arranged about a plane where the partition plate 60 is. Since the partition plate 60 is arranged at a middle portion of the container 10, the first washing tank 111 and the second washing tank 112 are symmetrical in structure. In addition, the first water supply system 41 and the second water supply system 42 have similar structures and a same weight, the first water supply system 41 is mounted to a bottom wall surface of the first washing tank 111, and the second water supply system 42 is mounted to a bottom wall surface of the second washing tank 112, such that the dish washer can have a symmetrical and stable structure.
Furthermore, referring to
As an exemplary embodiment, in order to enable the dish washer to have a more stable structure, the water softener 401 and the water pump 402 of the water supply system are arranged in a diagonal line of a bottom wall of the washing tank 11, and the cup assembly 404 of the water supply system 40 is located between the water softener 401 and the water pump 402.
For example, the water outflow end of the water supply duct 403 is in communication with the spraying duct 20 through the pressure-maintaining duct 50, and the diameter of the pressure-maintaining duct 50 is greater than that of the water supply duct 403, such that a water pressure in the water supply duct 403 is more stable.
