Detailed Implementation

[0068] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0069] Referring to Figures 1 to 4, the drying system 100 of the dishwasher 1000 according to an embodiment of this application includes a washing pump 10 and an air blowing device 16. The washing pump 10 includes a pump chamber 110, and the air blowing device 16 communicates with the pump chamber 110 and is adapted to blow air into the pump chamber 110. Specifically, in related technologies, after cleaning, water remains in the washing pump. This residual water is not easily evaporated, and long-term retention of residual water in the washing pump can produce odors, reducing the cleanliness and hygiene of the drying system or the dishwasher 1000, which is detrimental to long-term use by the user. In addition, residual water that remains in the washing pump for a long time can corrode the washing pump, reducing its service life and increasing the user's operating costs. Therefore, the drying system 100 of this application includes an air blowing device 16 that can blow air into the pump chamber 110 of the washing pump 10. After the drying system 100 completes the cleaning work, the air blowing device 16 can blow air into the pump chamber 110. The air entering the pump chamber 110 can dry the residual water in the pump chamber 110. Alternatively, the airflow generated by the air blowing device 16 can blow the airflow into the pump chamber 110, and the airflow can drive the residual water in the pump chamber 110 to be discharged. This can improve the cleanliness of the washing pump 10 and help protect the washing pump 10.

[0070] Specifically, when the drying system 100 is working, the washing pump 10 can drive water circulation, draw water from the water tank or water cup 30, and generate a high-pressure water flow, causing the water flow to impact the items to be cleaned at high speed, thereby enhancing the cleaning effect. When the drying system 100 completes the cleaning, there may be residual washing water in the washing pump 10. The cleaned washing water may contain detergent and impurities. Therefore, if the washing water is not cleaned, it will corrode the washing pump 10 and the internal space of the pump chamber 110, producing an odor.

[0071] Alternatively, after cleaning the washing pump 10, clean water is introduced into the washing pump 10 to rinse the items to be cleaned and the washing pump 10. If there is residual clean water in the washing pump 10, the air blowing device 16 blows air into the pump chamber 110 to dry the clean water and prevent the pump chamber 110 from being damp for a long time and growing bacteria.

[0072] According to the embodiment of this application, the drying system 100, by providing the air blowing device 16, can dry the washing pump 10 and its internal chamber, preventing residual water from accumulating inside the washing pump 10 and causing bacteria growth and odor, thereby improving the cleanliness of the washing pump 10, protecting the washing pump 10, and improving the cleaning effect of the drying system 100.

[0073] In some embodiments of this application, the air blowing device 16 is connected to the upstream of the pump chamber 110. Specifically, when the air blowing device 16 is connected to the upstream of the pump chamber 110, the airflow enters the pump chamber 110 from the upstream opening, and the airflow direction can be consistent with the water flow direction. Furthermore, blowing air from the upstream opening utilizes the structural design within the pump chamber 110 to promote rapid airflow discharge, making the drying process of the entire pump chamber 110 more efficient; it also helps to promote uniform gas distribution within the pump chamber 110, improving the drying effect. The airflow can more evenly push the moisture out, making the cleaning and drying process more thorough.

[0074] Specifically, referring to Figure 1, the air blowing device 16 being connected to the upstream of the pump chamber 110 facilitates spatial arrangement, allowing for the placement of drainage structures or other components in the downstream area of ​​the pump chamber 110. This improves the cleaning effect of the washing pump 10 and enhances the functionality and structural compactness of the drying system 100. Furthermore, the connection of the air blowing device 16 to the upstream of the pump chamber 110 facilitates its proximity to other components, enabling it to connect to multiple components simultaneously, thereby improving both the blowing and cleaning effects. For example, when the air blowing device 16 is connected to the upstream of the pump chamber 110, the drying system 100 may include a water cup 30, which is connected to the first inlet 10 of the pump chamber 110 via a pipe, with the air blowing device 16 connected to the pipe or its air outlet connected to the pipe.

[0075] In some embodiments of this application, the air blowing device 16 is connected to the first inlet 101 of the pump chamber 110, thereby allowing airflow to enter the pump chamber 110 from the first inlet 101 and exit from the outlet. This can promote the rapid discharge of airflow and effectively reduce water retention, especially in low-lying areas or dead corners of the pump chamber 110, preventing residual water from accumulating.

[0076] Referring to Figure 7, in some other embodiments of this application, the pump chamber 110 is provided with a vent 104, and the air blowing device 16 is connected to the vent 104. Thus, gas can directly enter the pump chamber 110 from the vent, which helps to improve the ventilation or blowing effect. Specifically, the air blowing device 20 can be directly connected to the washing pump 10, allowing the air blowing device 16 to be connected to the body of the washing pump 10.

[0077] Furthermore, referring to Figure 6, the drying system 100 includes a check valve 20, which is located between the vent 104 and the air blowing device 16 and is configured to be unidirectional in the air blowing direction. That is, the connection between the pump chamber 110 and the air blowing device 20 can be adjusted via the valve. For example, referring to Figure 6, the air blowing device 16 is connected to the check valve 20, which is located between the vent 104 and the air blowing device 20.

[0078] Referring to Figures 2 and 4, in some embodiments of this application, the pump chamber 110 includes a first drain outlet 102. An air blowing device 16 blows air into the pump chamber 110, driving the fluid within the pump chamber 110 to flow towards the first drain outlet 102. Thus, the airflow generated by the air blowing device 16 can drive the fluid or residual water within the pump chamber 110 to be discharged from the first drain outlet 102. Specifically, when the air blowing device 16 blows air into the pump chamber 110, it can dry the residual water inside the pump chamber 110, blowing it out. The residual water can then be discharged through the first drain outlet 102, thereby achieving the effect of cleaning the washing pump 10. Alternatively, the air blowing device 16 can blow air into the pump chamber 110, driving the residual water within the pump chamber 110 to flow towards the first drain outlet 102, and the blowing can continue for a period of time, drying the internal components of the pump chamber 110 and the inner wall of the washing pump 10, so that the washing pump 10 is in a dry state.

[0079] More specifically, a humidity detector can be installed in the pump chamber 110. The humidity detector transmits signals with the air blowing device 16. When the humidity detector reaches a predetermined value, the air blowing device 16 stops blowing air into the pump chamber 110. This can improve the drying effect of the washing pump 10 and help improve the intelligence and automation of the drying system 100 and the dishwasher 1000.

[0080] Furthermore, referring to Figure 1, in some embodiments of this application, the dishwasher 1000 includes a water cup 30, which can be used to store washing water. In use, the water cup 30 is connected to the washing pump 10, and the washing pump 10 draws water from the water cup 30, pressurizes the water in the water cup 30, and uses it to rinse the items to be cleaned.

[0081] In some embodiments of this application, a first drain port 102 is provided on the pump chamber 110, which can effectively and quickly drain water from the pump chamber 110, reducing water retention and accumulation. Combined with the air blowing device 16, it helps to drive the fluid or residual water in the pump chamber 110 to be discharged from the first drain port 102, thereby keeping the inside of the pump chamber 110 dry and preventing bacterial growth or odor. In addition, providing a first drain port 102 on the pump chamber 110 can reduce additional pipes or valves, which helps to simplify the structure.

[0082] Referring to Figure 4, the first drain outlet 102 can be configured as a long strip extending along the first direction, which can expand the water outlet range, wherein the first direction is perpendicular to the axial direction of the washing pump 10.

[0083] The washing pump 10 includes a pump housing 11 and a support frame 13. The pump housing 11 forms a pump chamber 110, and the support frame 13 is connected to the bottom wall of the pump housing 11. A first drain outlet 102 is located on the side of the pump housing 11 near the support frame 13. The first drain outlet 102 is located on the inner wall of the pump chamber 110. The pump housing 11 is constructed in a cylindrical shape to facilitate water flow within the pump housing 11. The first drain outlet 102 is constructed as an elongated strip extending circumferentially.

[0084] Referring to Figure 4, in some embodiments of this application, the first drain outlet 102 is connected to the bottom of the pump chamber 110. Fluid or residual water in the pump chamber 110 can easily flow to the first drain outlet 102 by gravity, which is beneficial to improving the drainage effect. Specifically, water flowing to the bottom of the washing pump 10 can be discharged through the bottom drain outlet, which is beneficial to cleaning the residual water in the washing pump 10. The air blowing device 16 can also blow the residual water at the bottom of the pump chamber 110 out from the first drain outlet 102, further improving the drying effect in the pump chamber 110.

[0085] Referring to Figure 2, the drying system 100 includes a bypass channel 50. One end of the bypass channel 50 is connected to the first drain outlet 102, and the other end is connected to a water cup 30. In this way, water discharged from the first drain outlet 102 can flow into the water cup 30 through the bypass channel 50, thereby collecting the washing water. The washing water collected in the water cup 30 can be used for the next round of washing or discharged through the water cup 30.

[0086] In some embodiments of this application, the water cup 30 and the washing pump 10 are connected by a pipe, and the cross-sectional area of ​​the bypass channel 50 is smaller than the cross-sectional area of ​​the pipe, so as to prevent the water in the water cup 30 from flowing back to the washing pump 10.

[0087] In some embodiments of this application, the cross-sectional area of ​​the bypass channel is less than 1 / 5 to 2 / 5 of the cross-sectional area of ​​the pipe body. Specifically, if the cross-sectional area of ​​the bypass channel is too small, it will be difficult for the water from the washing pump 10 to be discharged through the bypass channel. If the cross-sectional area of ​​the bypass channel is too large, water may flow back to the washing pump 10. Therefore, by reasonably setting the relationship between the cross-sectional area of ​​the bypass channel and the cross-sectional area of ​​the pipe body, the backflow phenomenon can be avoided while achieving the drainage effect.

[0088] More specifically, the bypass channel 50 is tubular, and its minimum inner diameter is no more than 10 mm, so as to reasonably control the size of the bypass channel 50.

[0089] In some embodiments of this application, a one-way valve is provided in the bypass channel 50. The one-way valve is configured to allow one-way flow from the first drain outlet 102 to the water cup 30, preventing water in the water cup 30 from flowing back into the pump chamber 110. Specifically, in practical applications, referring to Figure 1, the minimum water level in the water cup 30 may be higher than the minimum water level in the washing pump 10. Therefore, in order to prevent water in the water cup 30 from flowing directly into the pump chamber 110 of the washing pump 10 through the bypass channel 50, a one-way valve can be provided in the bypass channel 30 or the first drain outlet 102 to prevent water in the water cup 30 from flowing back into the pump chamber 110.

[0090] In addition, since the lowest water level in the water cup 30 may be higher than the lowest water level in the washing pump 10, residual washing water will generally be generated in the washing pump 10. By setting the first drain outlet 102 at the lowest point of the water level in the pump chamber 110, the residual water can be easily discharged through the first drain outlet 102, which can improve the drainage effect.

[0091] Referring to Figure 2, in some embodiments of this application, the washing pump 10 includes a first connector 12 communicating with the first drain outlet 102, and the water cup 30 is provided with a second connector 31 communicating with the interior of the water cup 30. The second connector 31 is located on the side close to the washing pump 10. Thus, the second connector 31 can be close to the washing pump 10, which facilitates shortening the path of the bypass channel 50 and constructing the shortest distance between the water outlet of the washing pump 10 and the water inlet of the water cup 30, thereby simplifying the structure. Specifically, in practical applications, the bypass channel 50 can connect the first drain outlet 102 and the interior of the water cup 30 by connecting the first connector 12 and the second connector 31, so that the water discharged from the first drain outlet 102 can enter the water cup 30.

[0092] In some embodiments of this application, the first connector 12 is located outside the washing pump 10, facilitating connection to the bypass channel 50 or pipeline. More specifically, the first connector 12 extends along an axial direction perpendicular to the washing pump 10, and the first connector 12 and the first drain outlet 102 are opposite each other along the axial direction of the washing pump 10. Specifically, the first drain outlet 102 and the first connector 12 extend in the same direction and are opposite each other along the axial direction, allowing water discharged from the first drain outlet 102 to quickly enter the first connector 12, thereby increasing the drainage volume and improving drainage efficiency.

[0093] Specifically, referring to Figure 2, the lower part or bottom of the water cup 30 is provided with a second connector 31. One end of the bypass channel 50 is connected to the first connector 12, and the other end is connected to the second connector 31, so that the water from the first drain outlet 102 can be discharged into the water cup 30 through the bypass channel 50.

[0094] In some embodiments of this application, the first connector 12 is provided with a first interface 121, the second connector 31 is provided with a second interface 311, and the bypass channel 50 includes a first connecting segment and a second connecting segment. One end of the first connecting segment is connected to the first interface 121 and the other end is connected to one end of the second connecting segment. The other end of the second connecting segment is connected to the second interface 311, which facilitates the connection between the bypass channel 50 and the first connector 12 and the second connector 31, thereby improving the tightness of the connection.

[0095] In some embodiments of this application, the extension lines of the first connecting segment and the second connecting segment have an angle, which can avoid pipeline interference between the water cup 30 and the washing pump 10.

[0096] Preferably, the extension lines of the first connecting segment and the second connecting segment have an included angle of 90 degrees. Specifically, the angle can be adjusted according to the positional relationship between the water cup 30 and the washing pump 10 to achieve a avoidance function, for example, the included angle is 60 degrees, 70 degrees or 80 degrees.

[0097] In some embodiments of this application, the first connecting segment and the second connecting segment are constructed as an arc transition, which can facilitate fluid flow.

[0098] Furthermore, the pump chamber 110 includes a second drain outlet 103. The washing pump 10 is adapted to drive fluid from the first inlet 101 of the pump chamber 110 to the second drain outlet 103, thereby driving the fluid to flow into the second drain outlet 103, or allowing the airflow to continue blowing through the second drain outlet 103, thereby improving the drying effect. Even further, the vent 104 and the second drain outlet 103 are arranged opposite to each other on the pump chamber 110, which can shorten the airflow path and further improve the drying effect.

[0099] Referring to Figures 3 and 4, in some embodiments of this application, the dishwasher 1000 includes a spray device 40, with a second drain outlet 103 connected to the spray device 40. Thus, the washing pump 10 can send pressurized washing water through the second drain outlet 103 into the spray device 40, where it is sprayed out to clean the items. The spray device 40 can expand the cleaning area, allowing the washing water to fully contact the items to be cleaned during washing. Specifically, in practical applications, cleaning water or washing water can enter the pump chamber 110 from the first inlet 101, pass through the second drain outlet 103, and enter the spray device 40, where it is sprayed onto the items to be cleaned. The sprayed washing water can flow naturally downwards to the water storage chamber 310 of the water cup 30, and then be drawn out again by the washing pump 10, pressurized, and sprayed out from the spray device 40 to achieve high-pressure cleaning. Furthermore, the washing water can be recycled during the washing process, which helps to save water.

[0100] Furthermore, the air blowing device 16 can blow air into the pump chamber 110, and the airflow can flow from the pump chamber 110 to the second drain port 103. Thus, the airflow can be blown towards the spray arm through the second drain port 103 and sprayed out from the spray arm. During the airflow process, air can be blown into the connecting pipe between the washing pump 10 and the spray device 40 and the water flow pipe of the spray device 40. During the air blowing process, the airflow can drive the fluid in the pipe to flow out along the water flow path, thereby achieving the effect of draining the residual water in the pipe, which is beneficial to improving the cleanliness of the drying system 100. Continuous air blowing can dry the above-mentioned pipes, and after cleaning, the cleaning components are kept dry and clean, avoiding residual water inside the drying system 100 or internal dampness that breeds bacteria.

[0101] Furthermore, after the fluid is blown out from the spray device 40, the air blown by the air blowing device 16 can continue to blow out from the spray device 40, and then onto the surface of the items being cleaned. The airflow can drive the water droplets on the surface of the items being cleaned, such as tableware, thereby facilitating the drying of the tableware. Specifically, since the tableware is inside the dishwasher 1000, the water droplets on the surface of the tableware take a long time to dry naturally, and the environment inside the dishwasher 1000 is humid, making it even longer for the tableware to dry naturally and prone to bacterial growth. The air blowing device 16 can effectively dry the washing pump, the spray device, and the tableware.

[0102] Referring to Figure 3, in the drying system 100 according to an embodiment of this application, the spray device 40 includes a pipe and a spray arm. One end of the pipe is connected to a second drain outlet 103, and the other end is connected to the spray arm, so that washing water can be sent from the second drain outlet 103 through the pipe to the spray arm. The pipe can extend the delivery distance of the washing water, thereby allowing the washing water to be sprayed from different positions or higher positions.

[0103] Furthermore, the pipeline includes a main line 41 and multiple branches. The main line 41 extends along a first direction, and the multiple branches are spaced apart along the main line 41 along the first direction. The multiple branches also extend along a second direction, with the first direction perpendicular to the second direction. This allows the washing water to be delivered in both directions, increasing the spray area and improving the flexibility of the spray arm arrangement. Specifically, the first direction can be vertical or the height of the dishwasher 1000, and the second direction can be horizontal or the width of the dishwasher 1000. That is, the main line 41 extends along the height of the dishwasher 1000, and the branches connect to the main line 41 and extend along the width. This allows the washing water to fully contact the tableware located in different positions within the dishwasher 1000. For example, the dishwasher 1000 can have upper and lower shelves inside the inner drum, with tableware placed on the upper and lower shelves respectively. During washing, the washing water can be delivered to the upper and lower parts of the dishwasher 1000 through the pipeline.

[0104] Furthermore, referring to Figure 3, the spray arms include a first spray arm 431, a second spray arm 432, and a third spray arm 433 arranged at intervals along a first direction. Multiple branches include a first branch 421, a second branch 422, and a third branch 423. The first spray arm 431, the second spray arm 432, and the third spray arm 433 are respectively connected to and rotatably linked to the first branch 421, the second branch 422, and the third branch 423. Thus, the first spray arm 431, the second spray arm 432, and the third spray arm 433 can be arranged at intervals along a vertical direction, and are respectively located at the upper, middle, and lower parts of the dishwasher 1000. The first spray arm 431, the second spray arm 432, and the third spray arm 433 are rotatable, allowing them to rotate and spray washing water during spraying, thereby improving the cleaning effect.

[0105] Specifically, the first spray arm 431 and the second spray arm 432 can clean the dishes located on the upper part of the dishwasher 1000, while the second spray arm 432 and the third spray arm 433 can be used to clean the dishes located on the lower part of the dishwasher 1000.

[0106] Referring to Figures 1 and 3, in some embodiments of this application, the drying system 100 includes an air distribution valve 15, which has an air inlet 1505 and multiple air outlets. An air blowing device 16 is connected to the air inlet 1505, and one air outlet is connected to a pump chamber 110. The air distribution valve 15 is configured to selectively connect and disconnect the air outlets from the air inlet 1505. Specifically, the multiple air outlets can be connected to different devices or components so that the air blowing device 16 can blow air onto multiple devices to achieve a drying effect on multiple devices. One air outlet is connected to the pump chamber 110, and the gas from the air blowing device 16 flows from the air inlet 1505 to the air outlet and then enters the pump chamber 110, thereby driving the fluid in the pump chamber 110 to be discharged and maintaining internal dryness.

[0107] Specifically, referring to Figures 1 and 5, the multiple air outlets may include a first outlet, a second outlet, and a third outlet. The water cup 30 is provided with a water cup outlet 303 and a drain channel 34. The first outlet is connected to the water cup outlet 303, which is connected to the water storage cavity 310 of the water cup 30, so that the air blowing device 16 can blow air into the water cup 30 to dry the water storage cavity 310. The second outlet is connected to the drain channel 34, which can dry the drain channel 34 of the water cup 30. The third outlet is connected to the first inlet 101 of the washing pump 10, which can dry the washing pump 10.

[0108] The air inlet 1505 is connected to the air blowing device 16, so that the gas from the air blowing device 16 can enter the air distribution valve 15 from the air inlet 1505. The air distribution valve 15 can send the blown air into the water cup 30, the water storage chamber 310, the drainage channel 34, or the washing pump 10.

[0109] More specifically, the air distribution valve 15 can selectively connect or disconnect the air inlet 1505 and the air outlet, controlling the connection and disconnection between the air blowing device 16 and the pump chamber 110, thereby improving operational reliability. For example, when the washing pump 10 is in the washing state, the pump chamber 110 contains a large amount of washing water. The air distribution valve 15 can disconnect the air inlet 1505 and the air outlet, separating the air blowing device 16 from the pump chamber 110 and preventing the washing water in the pump chamber 110 from entering the air blowing device 16 through the air outlet, thus preventing contamination or damage to the air blowing device 16.

[0110] Optionally, the air distribution valve 15 can selectively connect the air inlet 1505 to one or more of the multiple air outlets. In this way, when the air blowing device 16 is working, gas can enter the air distribution valve 15 from the air inlet 1505 and flow out from the multiple air outlets, realizing the gas diversion, thereby blowing air to multiple devices at the same time, which helps to improve drying efficiency.

[0111] For example, one of the multiple air outlets can be connected to the water cup 30. When the air distribution valve 15 connects the air inlet 1505 to the air outlet, the air blowing device 16 can blow air onto the water cup 30, thereby facilitating the drying of the water cup 30.

[0112] Specifically, referring to Figure 2, the drying system 100 includes a control valve 61, which is connected to and controls the air distribution valve 15. Thus, by controlling the control valve 61, one of the multiple air outlets of the air distribution valve 15 can be connected to the air inlet 1505 or not connected to the air inlet 1505.

[0113] In some embodiments of this application, the drying system 100 includes a heating device that heats the gas blown out by the air blowing device 16, thereby increasing the temperature of the airflow and improving drying efficiency. Specifically, the heating device can be located on the air blowing device 16 and configured to heat the airflow blown by the air blowing device 16 towards the pump chamber 110, making the airflow entering the pump chamber 110 a hot airflow. This accelerates the evaporation efficiency of residual water in the pump chamber 110, thereby improving the drying efficiency of the pump chamber 110 and maintaining a dry environment in the pump chamber 110. In conjunction with the foregoing, the heating device can also accelerate drying when the air blowing device 16 blows air towards the water cup 30 or the spray device 40, which is beneficial for improving drying efficiency. The heating device can also be used to heat the washing water, thereby increasing the temperature of the washing water and achieving hot water washing, which can have a sterilization and disinfection effect, and is beneficial for dissolving stains and improving the cleaning effect.

[0114] Referring to Figure 1, in some embodiments of this application, the air blowing device 16 includes a fan 161 and an air inlet pipe 162. One end of the air inlet pipe 162 is connected to the fan 161, and the other end blows air towards the air inlet 1505 of the pump chamber 110 or the air distribution valve 15. The airflow generated by the fan 161 enters the pump chamber 110 through the air inlet pipe 162, improving the stability of the airflow. Furthermore, the air inlet pipe 162 connecting the fan 161 and the air inlet 1505 optimizes the installation position of the fan 161 and improves the space utilization of the dishwasher 1000. Exemplarily, the air inlet pipe 162 can be configured as a flexible hose for easy arrangement. Exemplarily, the air inlet pipe 162 extends to a certain length, forming an air duct within it.

[0115] In some embodiments of this application, the blower 161 is an axial flow blower, which makes the structure of the blowing device 16 compact and can provide a larger air volume, making it easier for the blowing device 16 to provide high-speed airflow to the pump chamber 110 and improve the drying efficiency of the pump chamber 110.

[0116] In some embodiments of this application, the heating device can be located on the air inlet pipe 162 downstream of the fan 161, so that the air outlet of the fan 161 can flow through the heating device, which is beneficial to heating the airflow temperature, and the airflow is heated during the flow of the air inlet pipe 162, which is beneficial to improving the heating effect.

[0117] In some embodiments of this application, the blowing device 16 is connected to a one-way valve. The one-way valve is configured to be unidirectional in the blowing direction. That is, under the action of the one-way valve, the airflow blown by the blowing device 16 can only enter the pump chamber 110 in one direction, improving the blowing efficiency of the blowing device 16 and preventing the airflow or water flow in the pump chamber 110 from flowing back into the blowing device 16 when negative pressure is generated, which would affect the service life of the blowing device 16 and improve the reliability of the drying system 100. Exemplarily, the blowing device 16 may include a fan 161 and an air inlet pipe 162. The air inlet pipe 162 connects the outlet and the air inlet 1505 of the fan 161. The one-way valve may be installed at the outlet of the fan 161, or the one-way valve may be connected to the air inlet pipe 162.

[0118] Referring to Figure 1, in some embodiments of this application, the water cup 30 includes a water storage chamber 310 and a water distribution chamber 320, which are separated. The water storage chamber 310 has a water cup outlet 303, and the water distribution chamber 320 has a second inlet 302. The water cup outlet 303 is connected to the first inlet 101 of the pump chamber 110, and the second inlet 302 is connected to the second drain outlet 103. The water distribution chamber 320 is connected to the outlet or downstream of the washing pump 10. That is, the first inlet 101 of the pump chamber 110 is connected to the water storage chamber 310, and the outlet of the washing pump 10 is connected to the water distribution chamber 320. The water distribution chamber 320 is connected between the outlet of the washing pump 10 and the spray device 40. When the washing pump 10 is working, it draws water from the water storage chamber 310, pressurizes it, and sends it to the water distribution chamber 320, which then enters the spray device 40. Specifically, when the dishwasher 1000 is working, the pump body of the washing pump 10 draws water from the water storage chamber 310 of the water cup 30. The drawn water is discharged from the water cup 30, that is, it enters the first inlet 101 of the pump chamber 110 from the water cup outlet 303. After the water is pressurized in the pump chamber 110 of the washing pump 10, it is sent from the second drain outlet 103 of the pump chamber 110 to the second inlet 302, which is separated from the water storage chamber 310. The second inlet 302 is connected to the spray device 40. During washing, the second inlet 302 can also be used to enter water, which can send water to the spray device 40 and be sprayed out by the spray arm of the spray device 40.

[0119] More specifically, referring to Figure 5, the water distribution chamber 320 is provided with a first air outlet 321, a second air outlet 322, and a third air outlet 323. The first air outlet 321 is connected to the first spray arm 321, the second air outlet 322 is connected to the second spray arm 432, and the third air outlet 323 is connected to the third spray arm 433. A water distribution valve is provided within the water distribution chamber 320. The water distribution valve can selectively connect or disconnect the air blowing device 16 or the washing pump 10 from one or more of the first air outlet 321, the second air outlet 322, and the third air outlet 323. In other words, the washing pump 10 is connected to the spraying device 40 through the water distribution chamber 320, and the water distribution valve controls the connection or disconnection of the spray arms, thus allowing for flexible control of the spray arms. For example, one or more spray arms can be selected and operated depending on the actual situation. Similarly, the water distribution valve can control the air blowing between the air blowing device 16 and multiple spray arms, allowing the air blowing device 16 to select one or more spray arms to blow air according to the actual situation, thereby achieving multiple drying methods. For example, when there is water in multiple spray arms, the first spray arm 431 located at the top can be turned on first to dry the first spray arm 431, and then the second spray arm 432 can be turned on to dry the second spray arm 432. In this way, the water in the first spray arm 431 can be prevented from dripping downwards, thus improving the drying efficiency.

[0120] Referring to Figure 3, according to a specific embodiment of the drying system 100, the third air outlet 323 can be directly connected to the third spray arm 432 located at the bottom. The first air outlet 321 and the second air outlet 322 are located in the main channel 41. The main channel 41 is provided with channels that separately connect the first air outlet 321 and the first spray arm 431, as well as the second air outlet 322 and the second spray arm 432, thereby realizing the diversion of the first spray wall 431 and the second spray arm 432.

[0121] In some embodiments of this application, referring to Figure 1, the drying system 100 includes a drainage device 70. A drain outlet 304 is provided at the bottom of the water cup 30, connected to the drainage device 70 to drain water from the water cup 30. After drainage, a drain pipe 71 is connected, which can guide the drained water to a predetermined location. After the water in the water cup 30 is drained, the gas from the blowing device 16 can also be connected to the water storage chamber 310 of the water cup 30 through the air distribution valve 15, blowing air into the water storage chamber 310 to dry the water cup 30.

[0122] A drying system 100 according to a specific embodiment of this application is described below with reference to the accompanying drawings.

[0123] The drying system 100 is used in the dishwasher 1000. The following description uses the application of the drying system 100 in the dishwasher 1000 as an example. Referring to Figures 1 to 5, the drying system 100 includes a washing pump 10 and an air blowing device 16. The air blowing device 16 is connected to the pump chamber 110 of the washing pump 10. The air blowing device 16 pumps air into the pump chamber 110, and the airflow drives the residual water in the pump chamber 110 to be discharged. Specifically, the washing pump 10 is the main power source for washing, driving the washing water in the dishwasher 1000 to circulate back and forth between the water cup 30 and the spray arm. When washing stops, the drain device 70 discharges the water from the dishwasher 1000, and the air blowing device 16 also discharges the residual water from the washing pump 10.

[0124] In practical applications, the air blowing device 16 can be installed in the water line of the washing pump 10. The air blowing device 16 can be connected to the front end or upstream (first inlet 101) of the washing pump 10. The connection or connection between the air blowing device 16 and the pump chamber 110 can be adjusted by the air distribution valve 15.

[0125] More specifically, the pump chamber 110 has a first inlet 101 and an outlet. The first inlet 101 is connected to the water cup outlet 303 at the bottom of the water storage chamber 310 of the water cup 30, and the outlet is connected to the spray arm water passage or the water distribution chamber 320 of the water cup 30. These connection points can be connected by rubber hoses, so that the water in the water cup 30 flows to the spray arm or flows to the spray arm through the water distribution chamber 320 by the action of the washing pump 10, and is sprayed out through the spray arm. The sprayed washing water falls back by gravity and collects in the water storage chamber 310 of the water cup 30, realizing the circulation of washing water. The spray arm water passage connects the water cup outlet 303 of the water cup 30, the first inlet 101 of the pump chamber 11, and the water distribution chamber 320. The spray outlet 305 of the water distribution chamber 320 is connected to the spray arm.

[0126] An air blowing device 16 is installed at the front end of the washing pump 10 (first inlet 101). The washing pump 10 has a first drain outlet 102 on the pump chamber 110. The first drain outlet 102 is located at the lowest point of the gravity point of the pump chamber 110. A small water inlet is added to the water cup 30, and the first drain outlet 102 is connected to the water inlet through the bypass channel 50. When the air duct pressure is applied, the residual water in the washing pump 10 will be discharged into the water cup 30 through the first drain outlet 102, thus discharging the residual water in the washing pump 10. The air blowing device 16 will continue to work until the pump chamber 110 is dry. There is a valve on the air duct of the air blowing device 16 to control the connection or disconnection of the air blowing device 16 and the pump chamber 110. During this process, the washing pump 10 is unaffected during normal machine operation. The washing pump 10 is connected to the water cup 30 through a pipe. The water cup 30 has a channel connected to the spray arm, so that the water cup 30, the washing pump 10 and the spray arm form a circulating water path. When washing is completed, the water is drained from the dishwasher 1000, and the residual water in the washing pump 10 is also drained. After draining, the fan 161 is started to drive the water in the washing chamber out of the washing chamber through airflow, so that the water is no longer in the washing chamber, and finally the water is drained out of the dishwasher 1000.

[0127] The dishwasher 1000 according to the embodiments of this application includes the aforementioned drying system 100. By providing the aforementioned drying system 100 in the dishwasher 1000, the air blowing device 16 can blow air to the washing pump 10 to dry the washing pump 10. This can prevent residual water from accumulating in the washing pump 10 and causing bacteria growth and odor, thereby improving the cleanliness of the washing pump 10, protecting the washing pump 10, and thus improving the cleaning effect of the cleaning equipment.

[0128] As shown in Figures 1 and 14, the dishwasher 1000 according to an embodiment of this application includes: a water cup 30, a washing pump 10, a spray device 40, and an air blowing device 16.

[0129] Specifically, the water cup 30 is used to collect and store water. For example, at the start of the wash cycle, the wash water will flow into the water cup 30 so that the wash pump 10 can draw water from the water cup 30 for the dishwasher 1000 to clean the dishes. During the wash cycle, the wash water falls into the water cup 30 after cleaning the dishes in the wash chamber. After the wash cycle is completed or when drainage is required during the wash cycle, the wash water is stored in the water cup 30 and the water in the water cup 30 can be drained using the drain device 17.

[0130] The washing pump 10 is used to pump water from the water cup 30 to the spray device 40. The inlet of the washing pump 10 is connected to the water cup 30. When it is necessary to clean the tableware, the washing pump 10 can send the water from the water cup 30 to the washing chamber and clean the tableware in the washing chamber by rinsing or other means.

[0131] The spray device 40 is connected to the outlet of the washing pump 10. The washing pump 10 can pump water from the water cup 30 to the spray device 40 and use the spray device 40 to clean the tableware.

[0132] The air blowing device 16 is connected to the inner cavity of the washing pump 10 and can blow air into the washing pump 10. When the airflow passes through the washing pump 10, it can dry the inner cavity of the washing pump 10. When there is water in the washing pump 10, the air pressure can drive the water in the pump cavity to be discharged, thus removing residual water. In addition, the airflow can be sent to the spray device 40. During the airflow's journey to the spray device 40, it can dry the pipes along the way. When the airflow reaches the spray nozzles of the spray device 40, it can dry the spray device 40 and the spray nozzles. Furthermore, the airflow can be sprayed from the nozzles to dry the tableware and the inner wall of the washing chamber.

[0133] In this application, the washing pump 10 has a heating unit or heating device. The heating unit can be integrated into the washing pump 10, and it heats the airflow passing through the washing pump 10. During the dishwashing process of the dishwasher 1000, the heating unit can be used to heat the water, and the heated hot water can be sent into the washing chamber to clean the dishes, improving cleaning efficiency and effectiveness. Furthermore, the heating unit in this application can be configured to heat the airflow. When the air blowing device 16 drives the airflow through the washing pump 10, the heating unit heats the airflow. The heated airflow can more easily remove moisture from the pipes, improving the drying effect of the dishwasher 1000.

[0134] According to the embodiments of this application, the dishwasher 1000 can use a heating unit to heat water and airflow. By heating the water with the heating unit, the cleaning efficiency and effect of the dishwasher 1000 can be improved. By heating the airflow with the heating unit, the internal cavity of the dishwasher 1000 can be dried better with hot air, thereby optimizing the internal environment of the dishwasher 1000. This allows tableware to be kept in the dishwasher 1000 for a longer period of time while remaining clean, thus optimizing the performance of the dishwasher 1000.

[0135] The air blowing device 16 in this application can have multiple drying modes. For example, the airflow delivered by the air blowing device 16 can be sent to the washing pump 10 to remove residual water and dry the inner cavity of the washing pump 10; or, the airflow delivered by the air blowing device 16 can be sent to the pipeline leading to the spray device 40 to remove residual water and dry the pipeline; or, the airflow delivered by the air blowing device 16 can be sent to the spray device 40 to remove residual water and dry the spray device 40; or, the airflow delivered by the air blowing device 16 can be sent to the drain device 17 to remove residual water and dry the drain device 17; or, the airflow delivered by the air blowing device 16 can also be sent to the water cup 30 to remove residual water and dry the water cup 30, etc. The dishwasher 1000 in this application can include, but is not limited to, one or more of the above-mentioned operating modes. Of course, the above description is only some embodiments of this application and is not a limitation on the scope of protection of this application.

[0136] As mentioned above, when the dishwasher 1000 needs to be thoroughly cleaned and dried, air needs to be directed to different locations. Therefore, an air distribution valve 15 is provided in this application to adjust the blowing direction of the airflow delivered by the air blowing device 16.

[0137] As shown in Figures 8 to 14, in some embodiments, the dishwasher 1000 includes an air distribution valve 15, which is connected to the air blowing device 16, the washing pump 10, and the water cup 30, respectively. The air distribution valve 15 is configured to switchably connect any two of the air blowing device 16, the washing pump 10, and the water cup 30. For example, the air distribution valve 15 connects the air blowing device 16 and the washing pump 10; or, the air distribution valve 15 connects the air blowing device 16 and the water cup 30; or, the air distribution valve 15 connects the washing pump 10 and the water cup 30, etc.

[0138] The air distribution valve 15 of this application may have an air inlet 1505, a first outlet 1501 and a second outlet 1502, wherein the first outlet 1501 is connected to the water cup 30 and the second outlet 1502 is connected to the inlet of the washing pump 10. The air distribution valve 15 may be in one or more of the following states, including but not limited to.

[0139] In the first connected state, the air inlet 1505 is connected to the first outlet 1501 and disconnected from the second outlet 1502. The air blowing device 16 is connected to the water cup 30 and disconnected from the washing pump 10. The airflow of the air blowing device 16 can be controlled to be sent to the water cup 30 to dry the water cup 30.

[0140] In the second connected state, the air inlet 1505 is connected to the second outlet 1502 and disconnected from the first outlet 1501. The air blowing device 16 is connected to the washing pump 10 and disconnected from the water cup 30. The airflow of the air blowing device 16 can be controlled to be sent to the washing pump 10 to dry the washing pump 10. At the same time, the heating unit of the washing pump 10 can be used to heat the airflow to improve the drying effect on the dishwasher 1000.

[0141] In the first cutoff state, the air inlet 1505 is disconnected from both the first outlet 1501 and the second outlet 1502, while the first outlet 1501 and the second outlet 1502 are connected. The washing pump 10 is connected to the water cup 30. At this time, the air blowing device 16 will not blow air to the washing pump 10 and the water cup 30. However, the water cup 30 is connected to the inlet of the washing pump 10, allowing water from the water cup 30 to be easily delivered to the washing pump 10 through the air blowing device 16, thereby enabling the dishwasher 1000 to clean the dishes.

[0142] Through the above implementation method, the airflow direction of the blowing device 16 can be controlled by the air distribution valve 15, thereby achieving drying of different positions inside the dishwasher 1000 and thus optimizing the drying effect inside the dishwasher 1000.

[0143] Optionally, the air distribution valve 15 includes: a housing 151, an air inlet 1505, a first outlet 1501, and a second outlet 1502 disposed on the housing 151, the first outlet 1501 and the second outlet 1502 being distributed circumferentially along the housing 151; and an air distribution member 152, rotatably disposed on the housing 151 along the circumferential direction, the air distribution member 152 being configured to open and close the first outlet 1501 and the second outlet 1502 by rotation. Thus, a person can switch between the aforementioned first connected state, second connected state, and first closed state by rotating the air distribution member 152, simplifying the structure and control of the air distribution valve 15 and facilitating quick adjustment of the drying state of the dishwasher 1000.

[0144] As shown in Figures 10 to 14, in some embodiments, the dishwasher 1000 includes a drain device 17 connected to an air distribution valve 15. The drain device 17 is connected to a water cup 30, and water in the water cup 30 can be discharged under the action of the drain device 17, thereby realizing the drainage of water in the water cup 30. The drain device 17 can be configured as a suction drain; specifically, water can be drawn from the drain outlet using the drain device 17, and then the drawn water can be discharged from the water cup 30.

[0145] Optionally, the air diverter valve 15 has an air inlet 1505, a first outlet 1501, a second outlet 1502, and a third outlet 1503. The first outlet 1501 is connected to the water cup 30, the second outlet 1502 is connected to the inlet of the washing pump 10, and the third outlet 1503 is connected to the drain device 17. The air diverter valve 15 can switch the direction of airflow. It can connect the air inlet 1505 to at least one of the first outlet 1501, the second outlet 1502, and the third outlet 1503, or it can isolate the air inlet 1505 from all three outlets. By providing multiple outlets, the direction of airflow can be easily controlled, facilitating the drying of different areas of the dishwasher 1000 and improving the overall drying effect of the dishwasher 1000. The air distribution valve 15 has multiple connected states. In the connected state, the air distribution valve 15 controls at least one of the first outlet 1501, the second outlet 1502, and the third outlet 1503 to open and connect to the air inlet 1505. It can control the direction of airflow to optimize the air drying effect on the dishwasher 1000 and improve the drying efficiency and effect of the dishwasher 1000.

[0146] As shown in Figure 11, the air distribution valve 15 has a fourth connected state. In this fourth connected state, the air inlet 1505 is connected to the third outlet 1503 and disconnected from the first outlet 1501 and the second outlet 1502. In this fourth connected state, the third outlet 1503 is open, allowing airflow to be delivered to the drainage assembly after passing through the air distribution valve 15, thus facilitating the drying of the drainage assembly. Since the drainage assembly may contain a large amount of water, introducing air into the drainage assembly separately increases the air pressure of the airflow delivered to it, thereby improving the drainage effect.

[0147] As shown in Figure 12, the multiple connection states include a fifth connection state. In the fifth connection state, the air inlet 1505 is connected to the first outlet 1501 and the second outlet 1502, but disconnected from the third outlet 1503. In this fifth connection state, the third outlet 1503 and the first outlet 1501 are open, allowing airflow to pass through the air distribution valve 15 and be delivered to the drain assembly and water cup 30 for drying. During the air-blowing drying process of the water cup 30, a portion of the airflow is sent to the drain assembly. The high-humidity airflow within the water cup 30 is then sent to the drain assembly, and the airflow entering the drain assembly blows away the moisture, effectively improving the air-blowing drying effect on the water cup 30 and the drain assembly.

[0148] As shown in Figure 13, the multiple connection states include a sixth connection state. In the sixth connection state, the air inlet 1505 is connected to the second outlet 1502 and disconnected from the first outlet 1501 and the third outlet 1503. In this sixth connection state, the second outlet 1502 is open, and the airflow can be sent to the washing pump 10 after passing through the air distribution valve 15, facilitating the drying of the washing pump 10. Therefore, introducing airflow separately into the washing pump 10 can improve the drying effect of the washing pump 10.

[0149] Additionally, as shown in Figure 14, the air distribution valve 15 has a second shut-off state. In this state, the air inlet 1505 is closed, disconnecting from the first outlet 1501, the second outlet 1502, and the third outlet 1503, while the first outlet 1501 and the second outlet 1502 are connected. At this time, the air inlet 1505 is closed, making it difficult for the airflow delivered by the blowing device 16 to enter the air distribution valve 15, and also making it difficult for the fluid flowing within the air distribution valve 15 to enter the blowing device 16 from the air inlet 1505. However, when the first outlet 1501 and the second outlet 1502 are connected, the fluid in the water cup 30 can be sent to the washing pump 10 through the air distribution valve 15. Thus, when the dishwasher 1000 is cleaning dishes, the washing pump 10 can use the water in the water cup 30 to clean the dishes, simplifying the control of the air distribution valve 15 and enabling the dishwasher 1000 to operate more stably and conveniently.

[0150] In some embodiments, the air distribution valve 15 includes a housing 151 and an air distribution component 152. The housing 151 has an air inlet 1505 and multiple outlets distributed circumferentially around the housing 151. The air distribution component 152 is rotatably mounted on the housing 151 circumferentially. The air distribution component 152 is configured to open and close the multiple outlets and the air inlet 1505 by rotation. This simplifies the structure of the air distribution valve 15, improves the stability and safety of its operation, and enables timely and rapid switching of airflow direction.

[0151] Optionally, the housing 151 is provided with a sealing section 1504, and the third outlet 1503, the first outlet 1501, the second outlet 1502, and the sealing section 1504 are distributed along the circumference of the housing 151. This allows the airflow direction to be controlled by the air distributor 152, simplifying the structure of the heat exchanger and improving the operational stability of the heat exchanger. In some examples, the third outlet 1503, the first outlet 1501, the second outlet 1502, and the sealing section 1504 are sequentially distributed along the circumference of the housing 151. The air distributor 152 can be configured to simultaneously block two adjacent outlets.

[0152] In conjunction with the foregoing embodiments, the aforementioned fourth, fifth, sixth, and closed states can be quickly achieved. In the fourth connected state, the air distributor 152 can block the fourth and fifth outlets, at which time the sixth outlet is open; in the fifth state, when the air distributor 152 rotates, it blocks the fifth outlet and the sealing part 1504, at which time the sixth and fourth outlets are open; in the sixth connected state, the air distributor 152 blocks the sixth and fourth outlets, and the fifth outlet is open; in the closed state, the air distributor 152 blocks the sixth outlet and the sealing part 1504, and the fourth and fifth outlets are open. Of course, the air distributor 152 in this application can be configured in other forms, which is beneficial for being configured to correspond to the aforementioned air outlet device having a first outlet 1501 and a second outlet 1502.

[0153] It can be seen that the air distribution component 152 blocks adjacent parts each time, so that the air distribution component 152 can be set as a continuous plate structure. Of course, the air distribution component 152 can also be set as multiple discontinuous plate structures, etc.

[0154] Optionally, the third outlet 1503, the first outlet 1501, the second outlet 1502 and the closure 1504 are distributed at equal intervals along the circumference of the housing 151.

[0155] As shown in Figures 8 to 14, in some embodiments, the air distribution component 152 includes a baffle 1521, which is movable circumferentially along the housing 151 to close and open the third outlet 1503, the first outlet 1501, and the second outlet 1502. The movement of the baffle 1521 can be used to switch the air distribution valve 15 between different connection states, simplifying the structure of the air distribution valve 15 and enabling rapid switching between different connection states.

[0156] The baffle 1521 is designed as a sheet that extends continuously along the circumference of the housing 151, thereby improving the structural strength of the baffle 1521 and facilitating the switching of the state of the air distribution valve 15. Of course, the baffle 1521 in this application can also be provided as multiple discontinuous sheets. For example, in some examples, the baffle 1521 has a first sheet portion and a second sheet portion distributed along the circumference of the housing 151.

[0157] The air distribution valve 15 is connected between the inlet of the washing pump 10 and the outlet of the water cup 30. Referring to the previous example, the first outlet 1501 is connected to the water cup 30, and the second outlet 1502 is connected to the washing pump 10. This fully satisfies the requirement of connecting the water cup 30 to the washing pump 10 during normal washing, and also meets the requirement of drying using the air blowing device 16, simplifying the structure of the dishwasher 1000 and optimizing its performance.

[0158] In some embodiments, the dishwasher 1000 includes a water distribution valve 14, which can be connected to a spray device 40. The spray device 40 may have multiple spray arms, and the water distribution valve 14 can be used to switch between water and air paths to select the flow direction of either water or air. Optionally, the spray device 40 may include a first spray arm 431, a second spray arm 432, and a third spray arm 433. The first spray arm 431, second spray arm 432, and third spray arm 433 are provided with drive holes. Under the action of airflow, the drive holes can drive the spray arms to rotate. Simultaneously, gas is ejected from the nozzles on the spray arms, directly spraying onto the tableware and blowing away water droplets. At this time, the rotating spray arms can evenly spray gas onto the tableware from all directions. After a certain period of time, the gas can dry the tableware and blow away residual water inside the pipes. This greatly shortens the drying time and improves the drying effect.

[0159] During the airflow or water flow process, the water can be introduced into the spray 40 after passing through the washing pump 10 and the water distribution valve 14. At this time, the water or airflow can be heated by the heating unit. Heating the water flow can improve the efficiency and effect of washing dishes. Heating the airflow can facilitate the drying of the inner cavity of the spray device 40, the washing cavity, and the dishes, thereby improving the drying efficiency and effect of the dishwasher 1000.

[0160] Optionally, the water distribution valve 14 may have a first connecting port and a second connecting port, wherein the first connecting port is connected to the water cup 30 and the second connecting port is connected to the spray device 40. The water distribution valve 14 has a first working state and a second working state. In the first working state, the first connecting port 141 is connected to the outlet of the washing pump 10, and in the second working state, the second connecting port 142 is connected to the outlet of the washing pump 10. Since the water distribution valve 14 is connected to the outlet of the washing pump 10, the water and airflow delivered from the washing pump 10 will enter the water distribution valve 14. At this time, the water distribution valve 14 can distribute the fluid to control the fluid to flow into the water cup 30 or into the spray device 40. The fluid passing through the washing pump 10 can be heated by a heating unit. This application mainly takes the use of the air blowing device 16 to blow air into the washing pump 10 as an example. The airflow will be heated during the process of passing through the washing pump 10, and the heated airflow is sent into the water distribution valve 14, which can have a diversion function. The water distribution valve 14 can deliver the airflow heated by the heating unit to the water cup 30, so as to dry and remove residual water from the interior space of the water cup 30 using hot air; or, the water distribution valve 14 can send the airflow heated by the heating unit to the spray device 40, so as to remove residual water and dry the pipes leading to the spray device 40, the inner cavity of the spray device 40, the spray nozzles of the spray device 40, the tableware in the washing chamber of the dishwasher 1000, and the interior of the washing chamber of the dishwasher 1000 using hot air; in addition, the water distribution valve 14 can be configured to control the airflow heated by the heating unit to be sent to both the spray device 40 and the water cup 30, thereby improving the drying efficiency and effect of the dishwasher 1000.

[0161] The heating unit in this application is integrated into the washing pump 10. In the dishwasher 1000 of the related art, this heating unit is used to heat the water passing through the washing pump 10 to improve cleaning efficiency and effect. In this application, the heating unit is also used to heat the air. Therefore, it is necessary to understand the operating status of the heating unit so that while using the washing pump 10 to heat the airflow, the safety hazards caused by dry burning are avoided. Therefore, in some embodiments of this application, the washing pump 10 includes a temperature measuring unit for detecting the fluid temperature inside the pump chamber of the washing pump 10. This allows for timely understanding of the heating status of the airflow by the washing pump 10, so as to control the airflow temperature and optimize the drying effect. In addition, the temperature measuring unit can be set to detect the temperature of the pump chamber wall, thereby avoiding the problem of excessively high pump chamber wall temperature during the heating of the airflow, further improving the stability and safety of the dishwasher 1000 during operation.

[0162] In some embodiments, the air blowing device 16 includes a fan 161 and an air inlet pipe 162. One end of the air inlet pipe 162 is connected to the fan 161, and the other end is used for blowing air. The fan 161 is an axial flow fan 161. The other end of the air inlet pipe 162 can be configured to blow air toward the washing pump. In conjunction with the aforementioned embodiments, the other end of the air inlet pipe 162 blows air toward the air distribution valve.

[0163] In this application, when the dishwasher 1000 enters the drying stage, the gas from the fan 161 enters the internal pipe of the dishwasher 1000 and shares the internal heating tube of the washing pump 10. The gas passes through the working heating tube to form hot air for drying.

[0164] Specific implementation details: When the dishwasher 1000 enters the drying stage, the air distribution valve 15 switches to level 3, the fan 161 and the washing pump 10 are connected, the fan 161 operates, and gas enters the pipeline, passing through the air distribution valve 15 into the washing pump 10. At this time, the heating element of the washing pump 10 (originally used to heat the water) is in working condition, heating the moving gas to form hot air.

[0165] Scenario 1: The water distribution valve 14 is switched to the spray arm direction (any first spray arm 431, second spray arm 432, third spray arm 43). Hot air passes through this passage, through the washing pipe of the dishwasher 1000, reaches the spray arm, and is finally sprayed out from the spray arm nozzle.

[0166] The effects achieved are: 1. Hot air is sprayed out from the nozzles and sprayed onto the tableware to dry it. 2. Hot air passes through the internal washing pipes and dries the residual water in the pipes, preventing moisture and bacterial growth.

[0167] Scenario 2: The water distribution valve 14 switches to the direction of the water cup 30. Hot air can reach the inner cavity of the water cup 30 through this passage, drying the cup, the lifting cup, and the filter, achieving complete drying of the inside of the water cup 30.
