[0051] A dishwasher, also called a dishwashing machine or a tableware washing machine, is a household kitchen appliance that replaces manual washing of tableware such as bowls, plates, cups, chopsticks, spoons, etc.

[0052] Current dishwashers generally include components such as a water tank, an inner container, a solenoid valve, and a drainage pipe. When washing, current dishwashers usually control the opening and closing of the solenoid valve to control the inflow and outflow of washing water into and out of the inner container. After the washing program of the dishwasher ends, the drainage solenoid valve opens, and the washing water in the inner container is usually directly discharged through the drainage pipeline. Since dishwashers usually need to wash tableware multiple times, and all the washing water in the inner container is discharged at the end of each wash, this will undoubtedly result in a relatively large water consumption of the dishwasher, thereby increasing the user's water cost.

[0053] Based on this, the embodiments of the present application provide a dishwasher, which can reduce the water consumption of the dishwasher, thereby improving the user experience.

[0054] Figure 1 and Figure 2 Both show a schematic perspective view of a dishwasher provided by the embodiments of the present application. Among them, Figure 1 and Figure 2 are schematic perspective views of the dishwasher from different perspectives. As shown in Figure 1 and Figure 2 the dishwasher 100 may include: a cabinet 10 and a water circuit assembly 20, and the water circuit assembly 20 may be disposed on the cabinet 10.

[0055] Also as shown in Figure 1 and Figure 2 the cabinet 10 may include: a cabinet shell 11 and an inner container 12. Among them, at least part of the inner container 12 and the water circuit assembly 20 may be disposed within the cabinet shell 11, and the cabinet shell 11 is used to protect the inner container 12 and the water circuit assembly. A washing chamber 12A is formed within the inner container 12.

[0056] In some embodiments, a bowl basket is further disposed within the inner container 12. The bowl basket is located within the washing chamber 12A and can be used to place tableware. Exemplarily, the bowl basket can be used to place larger tableware such as bowls, glass cups, and goblets.

[0057] Among them, the number of the bowl baskets may be one or multiple, and the number of bowl baskets can be set according to the size of the dishwasher 100. When there are multiple bowl baskets, the multiple bowl baskets may be spaced apart in the vertical direction. The connection relationship between the bowl basket and the washing chamber 12A may be a fixed connection, a detachable connection, a sliding connection, etc., and the present application does not limit this.

[0058] Figure 3 shows a schematic diagram of the connection relationship between the components of a dishwasher provided by the embodiments of the present application, Figure 4 shows a schematic diagram of the structure of an inner container of a dishwasher provided by the embodiments of the present application.

[0059] As shown inFigure 3 and Figure 4 As shown in Figure 4 , a water inlet 121 communicating with the washing chamber 12A is formed in the inner container 12, and the water inlet 121 is used for introducing washing water.

[0060] In some embodiments, a washing port 122 communicating with the washing chamber 12A is formed in the inner container 12, and the washing port 122 is a flowing port for the washing water.

[0061] In some embodiments, a drain port 123 communicating with the washing chamber 12A is formed in the inner container 12. Wherein, the drain port 123 may be located at the bottom of the washing chamber 12A, and the washing port 122 may be located above the drain port 123. Thus, when the drain port 123 is opened, the washing water can directly drain from the drain port 123 under the action of gravity, facilitating the drainage of the washing water from the washing chamber 12A.

[0062] In some embodiments, as Figure 4 and Figure 5 shown, the dishwasher 100 may further include: a spray assembly 25, which is located inside the inner container 12. Wherein, the spray assembly may be communicated with the water inlet 121, and the spray assembly 25 is arranged towards the washing chamber 12A to wash the tableware placed in the washing chamber.

[0063] Thus, after the washing water enters the inner container 12 through the water inlet, it is sprayed on the tableware placed in the washing chamber by the spray assembly 25, thereby improving the uniformity of spraying and the washing effect of the tableware.

[0064] In some embodiments, the dish basket of the dishwasher 100 may include: an upper dish basket and a lower dish basket, and the upper dish basket is arranged above the lower dish basket. The spray assembly 25 is used to spray water on the surfaces of the tableware on the upper dish basket and the lower dish basket to clean the oil stains and impurities on the tableware, and the washing water falling from the lower dish basket is drained through the drain port 123.

[0065] In some embodiments, the spray assembly 25 includes a connecting shaft 25A and a spray arm 25B. The connecting shaft 25A forms a cavity, an inlet and an outlet communicating with the cavity. The inlet may be communicated with the water inlet 121 to enable the washing water entering the inner container 12 to flow into the cavity of the connecting shaft 25A and flow out from the outlet; the spray arm 25B forms a spray cavity, spray holes and through holes communicating with the spray cavity. The through hole is arranged at the middle position of the spray arm 25B and extends in the up and down direction. The connecting shaft 25A passes through the through hole, and the spray arm 25B can rotate relative to the connecting shaft. The outlet is communicated with the through hole, and the openings of the spray holes face upwards, so that a part of the water flowing out from the outlet enters the spray cavity and is sprayed onto the dish basket through the spray holes, thereby enabling the spray arm 25B to rotate relative to the connecting shaft 25A.

[0066] Among them, an annular water outlet gap is formed between the spray arm 25B and the connecting shaft 25A. The water outlet gap is located below the outlet and is communicated with the outlet, so that another part of the water flowing out of the outlet forms a water curtain through the water outlet gap and is sprayed onto the dish basket.

[0067] The waterway assembly 20 is communicated with the inner container 12, and the waterway assembly 20 is used to provide washing water for the inner container 12.

[0068] Figure 6 It is a schematic three-dimensional structure diagram of a dishwasher provided by an embodiment of the present application. Figure 7 It is a schematic three-dimensional structure diagram of a dishwasher after removing the box body provided by an embodiment of the present application.

[0069] Such as Figure 3 and Figure 6 and Figure 7 As shown, the waterway assembly 20 includes a water tank 21, and the water tank 21 is used to store washing water for washing.

[0070] In some embodiments, the water tank 21 is arranged inside the box shell 11.

[0071] In some embodiments, the water tank 21 is arranged outside the box shell 11, and the present application does not make any limitation thereto.

[0072] Such as Figure 3 Figure 4 and Figure 6 As shown, the waterway assembly 20 includes a washing pump 22, and the washing pump 22 is used to pump washing water. Such as Figure 3 and Figure 6 and Figure 7 As shown, the waterway assembly 20 includes: a water distribution valve 23, and the water distribution valve 23 is used to control the direction and / or flow rate of the water flow.

[0073] Such as Figure 8 and Figure 9 As shown, the water distribution valve 23 is provided with a first inlet 231, a first outlet 232 and a second outlet 233. The first inlet 231 is communicated with the washing port 122, and the first outlet 232 is communicated with the spray assembly 25.

[0074] In some embodiments, the spray assembly 25 includes: a first spray assembly 251 and a second spray assembly 252. Among them, the first spray assembly 251 is arranged above the upper dish basket and is used to spray washing water on the upper dish basket. The first spray assembly 251 is communicated with the first outlet 232. The second spray assembly 252 is arranged above the lower dish basket and is used to spray washing water on the lower dish basket. The second spray assembly 252 is communicated with the water inlet 121.

[0075] Thus, during the washing process, the washing water entering the inner container 12 from the water inlet 121 can fall into the washing chamber after passing through the second spraying assembly 252, and then, under the action of the washing pump 22, it can flow through the washing port 122 and the water distribution valve 23 into the first spraying assembly 251 to spray the tableware to be washed in the upper basket.

[0076] In some embodiments, the first spraying assembly 251 can be communicated with the water inlet 121, and the second spraying assembly 252 can be communicated with the first outlet 232. The present application does not limit this.

[0077] Wherein, the water distribution valve 23 can include: a housing and a valve body. Wherein, a first inlet 231, a first outlet 232 and a second outlet 233 are provided on the housing, and a first communication channel 23A and a second communication channel 23B are provided in the housing. The first communication channel 23A is communicated with the first inlet 231 and the first outlet 232, and the second communication channel 23B is communicated with the first inlet 231 and the second outlet 233. The valve body is used to close or open the first communication channel 23A and the second communication channel 23B.

[0078] In some embodiments, the valve body is composed of two groups of sub-valves. Exemplarily, the sub-valve includes: a first sub-valve and a second sub-valve. The first sub-valve is used to close or open the first communication channel 23A, and the second sub-valve is used to close or open the second communication channel 23B.

[0079] In some embodiments, only one valve body is provided. A part of the valve body is rotatably arranged in the first communication channel 23A, and the other part of the valve body is arranged in the second communication channel 23B. By rotating the valve body, the first communication channel 23A and the second communication channel 23B can be closed or opened.

[0080] Exemplarily, the valve body can control the first communication channel 23A to be closed and the second communication channel 23B to be opened; the valve body can also control the first communication channel 23A to be closed and the second communication channel 23B to be opened; the valve body can also control the first communication channel 23A to be closed and the second communication channel 23B to be closed.

[0081] In some embodiments, as Figure 10 and Figure 11 shown, the dishwasher 100 can further include: a water outlet pipeline 30. One end of the water outlet pipeline 30 is communicated with the drain port 123, and the other end of the water outlet pipeline 30 extends out of the cabinet shell 11 for communicating with the outside. Exemplarily, the other end of the water outlet pipeline 30 can be communicated with the indoor drain pipe or floor drain. Thus, the dishwasher 100 can discharge the washing water through the water outlet pipeline 30.

[0082] In some embodiments, the material of the water outlet pipe 30 can be a metallic material. For example, the metallic material can be stainless steel, aluminum alloy, zinc-containing steel plate, or other metals. In this way, the water outlet pipe 30 has a certain strength, which can reduce the deformation of the water outlet pipe 30 when it collides with other objects and improve the service life of the water outlet pipe 30.

[0083] In some embodiments, the material of the water outlet pipe 30 can also be plastic. For example, the plastic can be acrylonitrile-butadiene-styrene (ABS) plastic, high impact polystyrene (HIPS), polycarbonate (PC), polyethylene glycol terephthalate (PET), etc. In this way, the water outlet pipe 30 can be integrally formed by an injection molding process through a mold, improving production efficiency and reducing production costs.

[0084] Among them, in some embodiments, a drainage pump 31 can be provided on the water outlet pipe 30. The drainage pump 31 is used to discharge the washing water in the inner tank 12 to the outside of the cabinet 11 through the drain port 123.

[0085] As Figure 3 and Figure 6 and Figure 7 As shown, the water circuit assembly 20 includes a breather 24. A first water inlet passage 24A and a reflux passage 24B are provided in the breather 24. A first water inlet 241 communicating with the first water inlet passage 24A is provided on the breather 24.

[0091] As Figure 11 shown, the washing pump 22 communicates with the washing port 122. The washing pump 22 may also be referred to as a water pump. The washing pump 22 is a machine for transporting liquids or increasing the pressure of liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. It is mainly used to transport liquids including water, oil, acid-base solutions, emulsions, suspension liquids, and liquid metals, etc.

[0092] Among them, the washing pump 22 may be a pump body such as a centrifugal pump, an axial flow pump, or a mixed flow pump, etc., and the present application does not limit this.

[0093] In some embodiments, the washing pump 22 may be provided on the pipeline between the inner tank 12 and the water distribution valve 23.

[0094] Among them, in some embodiments, the washing pump 22 may be used to discharge the washing water in the inner tank 12 to the water distribution valve 23, so that the washing water in the inner tank 12 flows through the water distribution valve 23 and returns to the spraying assembly or the washing water in the inner tank 12 flows through the water distribution valve 23 and into the water tank 21.

[0095] In some embodiments, the washing pump 22 may also be provided on the pipeline between the water distribution valve 23 and the respirator 24. The washing pump 22 may be used to discharge the washing water in the inner tank 12 to the water distribution valve 23, so that the washing water in the inner tank 12 flows through the water distribution valve 23 and into the water tank 21; or the washing pump 22 may be used to return the washing water in the water tank 21 to the water distribution valve 23 through the respirator 24 and flow into the inner tank 12 to realize the secondary utilization of the washing water.

[0096] The dishwasher 100 provided by an embodiment of the present application includes: a cabinet 10 and a waterway assembly 20. The cabinet 10 has a cabinet shell 11 and an inner tank 12. The inner tank 12 is disposed within the cabinet shell 11. The inner tank 12 has a washing chamber 12A, a water inlet 121, a washing outlet 122, and a drain outlet 123 that communicate with the washing chamber 12A. The drain outlet 123 is used to communicate with the outside to discharge the washing water. A spraying assembly 25 is disposed within the washing chamber. The washing chamber 12A can be used to place tableware to be washed. The washing water washes the tableware to be washed within the washing chamber 12A through the water inlet 121 and is discharged outside the cabinet shell through the drain outlet 123 after the washing is completed.

[0097] In addition, the waterway assembly 20 is used to supply washing water to the inner tank 12 and includes: a water tank 21, a washing pump 22, a water distribution valve 23, and a breather 24. The washing pump 22 communicates with the washing outlet 122. The water distribution valve 23 is provided with a first inlet 231, a first outlet 232, and a second outlet 233. The first inlet 231 communicates with the washing outlet 122. The first outlet 232 communicates with the spraying assembly. The breather 24 is provided with a first water inlet passage 24A and a return passage 24B. The breather 24 is provided with a first water inlet 241 and a first water outlet 242 that communicate with the first water inlet passage 24A. The first water inlet 241 is used to communicate with an external water source. The first water outlet 242 communicates with the water inlet 121. The breather 24 is further provided with a first return port 243 and a second return port 244 that communicate with the return passage 24B. The first return port 243 communicates with the water tank 21, and the second return port 244 communicates with the second outlet 233.

[0098] In this way, the washing water can flow out from the first water outlet 242 through the first water inlet passage 24A of the breather 24 and enter the inner tank 12. The washing water washes the tableware to be washed within the inner tank 12. When the dishwasher 100 is in the initial drainage stage, since there are more residual impurities carried by the washing water, the washing water within the inner tank 12 can be discharged outside the cabinet shell 11 through the drain outlet 123. In the subsequent washing stage, the dishwasher can control the first inlet 231 of the water distribution valve 23 to communicate with the first outlet 232. The washing water within the inner tank 12 flows to the water distribution valve 23 through the washing outlet 122 under the action of the washing pump 22, and is guided by the water distribution valve 23 into the spraying assembly 25 to further wash the tableware to be washed within the dishwasher, making full use of the washing water and reducing the waste of water resources.

[0099] After the last wash cycle of the dishwasher 100, during the drainage phase at the end of the last wash cycle, the wash water in the inner tank 12 is relatively clean. The first inlet 231 of the water distribution valve 23 can be controlled to communicate with the second outlet 233. Under the action of the wash pump 22, the wash water in the inner tank 12 can flow through the wash port 122 and the first inlet 231 into the second communication channel 23B in sequence, then through the second outlet 233 and the second return port 244 into the return channel 24B, and finally through the first return port 243 into the water tank.

[0100] When the pre-wash program or the hot rinse program of the dishwasher 100 runs next time, the water tank 21 and the inner tank 12 can be controlled to communicate. The water in the water tank 21 can flow from the first return port 243 into the return channel 24B under the action of gravity, then through the second return port 244 and the second outlet 233 into the second communication channel 23B, and then through the first inlet 231 and the wash port 122 back into the inner tank 12 to wash the tableware to be washed in the inner tank 12. In this way, the water tank 21 of the dishwasher 100 can recycle the wash water after the dishwasher 100 washes and use the wash water as the wash water for the next wash, so as to reduce the water consumption of the dishwasher 100 and reduce the user's water use cost.

[0101] In addition, the wash program of the dishwasher 100 is divided into 4 stages: main wash, cold rinse, hot rinse, and drying. Among them, water inlet is required in the 3 stages of main wash, cold rinse, and hot rinse. During laboratory tests, the required water inlet temperature is (15±2)°C, and the laboratory ambient temperature is (23±2)°C. When the outdoor temperature is relatively low, the temperature of the wash water entering the dishwasher 100 is relatively low. Therefore, in order to achieve the wash and drying effects, the wash pump is required to heat the wash water in the main wash and hot rinse stages. In this way, it will undoubtedly lead to relatively high energy consumption of the dishwasher 100.

[0102] In this application, at the end of the last wash cycle of the dishwasher 100, the wash water is recycled into the water tank 21. The wash water in the water tank 21 can be placed to absorb the heat in the air until it reaches room temperature. During the main wash stage of the next wash program, the water in the water tank 21 flows back into the inner tank 12 through the water distribution valve 23. During the main wash stage, the electric energy consumed to heat the water in the water tank 21 to the target temperature is less, saving the heating energy consumption of the water in the water tank 21 from 15°C to room temperature.

[0103] In some embodiments, as Figure 7 、 Figure 10 and Figure 12 shown, the dishwasher 100 may further include: a water purifier 60, which includes: a second water inlet 61 and a second water outlet 62. The second water inlet 61 is communicated with the first water outlet 242, and the second water outlet 62 is communicated with the water inlet 121.

[0104] In some embodiments, the water purifier includes a water softener which can be used to reduce the hardness of the washing water to extend the service life of the dishwasher. It can be understood that calcium and magnesium ions in water are the main causes of high water hardness. The water softener can use ion exchange technology to exchange functional ions on the resin with calcium and magnesium ions in water, thereby adsorbing and removing these ions and reducing the water hardness.

[0105] In this way, the hardness of the water entering the inner tank 12 of the dishwasher 100 can be reduced. Since at the end of the last wash, the washing water purified by the water purifier and flowing into the inner tank will be recycled to the water tank, the hardness of the water entering the water tank is also relatively low. Thus, the scale adhering to the heater in the water tank can be reduced, the heater in the water tank 21 can be protected, the service life of the dishwasher 100 can be extended, and the washing appearance can be improved, especially for tableware that is prone to water stains, such as stainless steel dinner plates, glass cups, etc.

[0106] In some embodiments, as Figure 13 shown, a second water inlet passage 24C is further provided in the breather 24. A third water inlet 245 and a third water outlet 246 communicating with the second water inlet passage 24C are provided on the breather 24. The third water inlet 245 communicates with the second water outlet 62, and the third water outlet 246 communicates with the water inlet 121.

[0107] Among them, when the dishwasher 100 is in the washing process, a large amount of water vapor and heat will be generated by the dishwasher 100, and these gases need to be discharged through the breather 24 to prevent the internal pressure of the dishwasher 100 from being too high or the humidity from being too high. Since the washing water entering the water purifier flows into the inner tank 12 through the breather 24, when the pressure in the inner tank 12 is too high, the inner tank 12 can discharge some gases through the breather 24 to adjust the pressure in the inner tank 12 and ensure the normal operation and extended service life of the dishwasher 100.

[0108] Figure 14 Fig. shows a schematic diagram of the circuit connection structure of a dishwasher provided by an embodiment of the present application. Figure 15 Fig. shows a schematic diagram of the connection relationship of internal components of the dishwasher provided by an embodiment of the present application. Figure 16 Fig. shows a three-dimensional structure schematic diagram of the dishwasher provided by an embodiment of the present application. In some embodiments, as Figure 14 、 Figure 15 and Figure 16 shown, the dishwasher 100 may further include: a controller 63, a first valve 70, and a water flow meter 80. The controller 63 is electrically connected to both the first valve 70 and the water flow meter 80. The first valve 70 may be provided on the water inlet pipeline 50, and the water flow meter 80 is used to detect the flow rate of the washing water flowing through the first water inlet passage 24A.

[0109] Among them, the controller 63 is a master control device that controls the motor or other controlled objects by changing the parameters in the circuit. It consists of multiple components, including a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller 63, etc. These components cooperate together to complete the coordination and command of the operation of the entire computer or control system.

[0110] The first valve 70 is a key control component of the fluid delivery system, and the first valve 70 is a pipeline accessory used to open and close the pipeline.

[0111] In some embodiments, the first valve 70 can be a solenoid valve. There is a sealed cavity inside the solenoid valve, with through holes opened at different positions, and each hole is connected to a different oil pipe. In the middle of the cavity is a piston, and on both sides are two electromagnets. When the electromagnet coil on one side is energized, the valve body will be attracted to that side, and by controlling the movement of the valve body, different oil discharge holes can be opened or closed. The oil inlet hole is usually always open. After the hydraulic oil enters different oil discharge pipes, it pushes the piston of the oil cylinder through the pressure of the oil, and then drives the piston rod and the mechanical device. In this way, by controlling the on and off of the current of the electromagnet, the mechanical movement can be controlled.

[0112] In some embodiments, as Figure 15 shown, the water flowmeter 80 can be arranged inside the respirator 24 and on the first water inlet passage 24A. The water flowmeter is used to detect the flow rate of the washing water flowing through the first water inlet passage.

[0113] In some embodiments, as Figure 17 shown, the water flowmeter 80 can be arranged on the pipeline between the first valve 70 and the respirator 24. The water flowmeter 80 is used to detect the flow rate of the washing water flowing through the first valve, so as to determine the flow rate of the washing water flowing through the first water inlet passage 24A.

[0114] In some embodiments, as Figure 18 shown, the water flowmeter 80 can also be arranged on the pipeline between the first water outlet 242 of the respirator 24 and the second water inlet 61 of the water purifier 60. The water flowmeter 80 is used to measure the flow rate of the washing water flowing out from the first water outlet 242, so as to determine the flow rate of the washing water flowing through the first water inlet passage 24A.

[0115] In this way, the controller 63 in the dishwasher 100 can send different command signals to the solenoid valve. The different command signals are used to indicate the on and off of the current of the electromagnet, so as to realize the control of the opening and closing of the solenoid valve.

[0116] In some embodiments, the first valve 70 can also be an electric valve, which generally includes components such as an electric actuator, a valve body, and a valve core. When the electric actuator receives a control signal, it converts this control signal into mechanical energy, reduces the rotational speed and increases the torque through a speed reducer, and drives the valve stem and the valve core to perform corresponding movements. The movement of the valve core changes the on-off state of the internal channel of the valve, thereby controlling the flow of the medium. If the valve core is fully opened, the medium can flow freely; if the valve core is fully closed, the medium is cut off.

[0117] In some embodiments, the first valve 70 can also be a mechanical valve, a pneumatic valve, a hydraulic valve, etc., and the present application does not limit this.

[0118] In this way, the controller 63 in the dishwasher 100 can obtain the flow rate of the washing water flowing through the first water inlet channel 24A through a flow meter. If the flow rate is equal to the preset flow rate set by the current washing program, the controller 63 controls the first valve 70 to close. When the washing program is in the water inlet stage, the controller 63 controls the first valve 70 to open, realizing the automatic control of the dishwasher 100 and improving the user experience.

[0119] In some embodiments, such as Figure 7 and Figure 19 shown, the dishwasher 100 may further include: a return pipeline 91 and a second valve 92. Among them, the return pipeline 91 includes: a first return branch 911 and a second return branch 912. One end of the first return branch 911 is communicated with the second outlet 233, and the other end is communicated with the second return port 244; one end of the second return branch 912 is communicated with the water tank 21, and the other end is communicated with the first return port 243; the second valve 92 is arranged on the return pipeline 91.

[0120] In some embodiments, the first return branch 911 can be an independently arranged pipeline, and the second return branch 912 can be a part of the breather 24, that is, the breather 24 includes: the second return branch 912, one end of the second return branch 912 is communicated with the first return port 243, and the other end is communicated with the water tank 21.

[0121] In some embodiments, both the first return branch 911 and the second return pipeline can be independently arranged pipelines. The first return branch 911 is used to communicate the second outlet 233 of the water distribution valve 23 and the second return port 244 of the breather 24. The second return branch 912 is used to communicate the first return port 243 of the breather 24 and the water tank 21.

[0122] In some embodiments, such as Figure 19As shown, the second valve 92 can be arranged on the first return branch 911. In this way, by controlling the second valve 92, the pipeline flow or blockage of the first return branch 911 can be controlled, so as to control whether the washing water in the water tank 21 flows back into the inner tank 12.

[0123] In some embodiments, the second valve 92 can also be arranged on the second return branch 912. In this way, by controlling the second valve 92, the pipeline flow or blockage of the first return branch 911 can be controlled, so that the washing water in the water tank 21 can flow back into the inner tank 12 through the breather 24.

[0124] In some embodiments, as Figure 20 shown, a third valve 93 is arranged on the water outlet pipeline 30. In this way, by controlling the third valve 93, it can be controlled whether the washing water in the inner tank is discharged from the dishwasher through the water outlet pipeline. In some embodiments, as Figure 20 and Figure 21 shown, the water tank 21 can be provided with a water inlet and outlet 211, and the water inlet and outlet 211 can be located at the bottom of the water tank 21; the water inlet and outlet 211 is located above the washing port 122.

[0125] In this way, the washing water in the water tank 21 can flow back into the inner tank 12 through the water distribution valve 23 under the action of gravity, and there is no need to set a water pump during the process of the washing water in the water tank 21 flowing back into the inner tank 12, thus reducing the energy consumption of the dishwasher 100.

[0126] In some embodiments, as Figure 20 and Figure 22 shown, the water tank 21 is also provided with an overflow port 212, and the overflow port 212 is located above the water inlet and outlet 211, and the overflow port 212 is communicated with the inner tank 12.

[0127] In this way, when there is more washing water in the inner tank 12, the washing water in the inner tank 12 can flow into the inner tank 12 through the overflow port 212 and finally be discharged from the dishwasher 100 through the water distribution valve 23.

[0128] In some embodiments, as Figure 20 and Figure 23 shown, a third water inlet channel 24D is further arranged in the breather 24, and a fourth water inlet 247 and a fourth water outlet 248 communicated with the third water inlet channel 24D are also arranged on the breather 24; the fourth water inlet 247 is communicated with the overflow port 212, and the fourth water outlet 248 is communicated with the water inlet 121.

[0129] It can be understood that in some embodiments, the fourth water outlet 248 can be the third water outlet 246 described above.

[0130] In some embodiments, the fourth water outlet 248 and the third water outlet 246 are not the same water outlet, and the present application does not limit this.

[0131] In this way, the washing water overflowing from the overflow water outlet 212 flows into the inner tank 12 through the third water inlet passage 24D of the breather 24. The breather 24 can adjust the pressure of the pipeline between the overflow water outlet 212 and the inner tank 12 to ensure the normal operation of the dishwasher 100 and extend its service life.

[0132] As described above, the above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
