[0042] The embodiments of this utility model 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 utility model, and should not be construed as limiting this utility model.

[0043] Combination Figures 1 to 4 The drying system 100 for a washing appliance according to an embodiment of this utility model includes a washing pump 10 and an air blowing device 20. The washing pump 10 includes a pump chamber 110, and the air blowing device 20 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 prolonged retention of residual water in the washing pump can produce odors, reducing the cleanliness and hygiene of the drying system or the washing appliance, which is detrimental to long-term use by the user. Furthermore, 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 utility model includes an air blowing device 20 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 20 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 20 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.

[0044] 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.

[0045] 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 20 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.

[0046] According to the embodiment of the present invention, the drying system 100, by providing the air blowing device 20, 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.

[0047] In some embodiments of this invention, the air blowing device 20 is connected to the upstream of the pump chamber 110. Specifically, when the air blowing device 20 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 can utilize 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.

[0048] Specifically, in combination Figure 1 The connection of the air blowing device 20 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 20 to the upstream of the pump chamber 110 also 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 20 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 20 connected to the pipe or its air outlet connected to the pipe.

[0049] In some embodiments of this utility model, the air blowing device 20 is connected to the first inlet 101 of the pump chamber 110, so that the airflow can enter the pump chamber 110 from the first inlet 101 and exit from the outlet, which can promote the rapid discharge of airflow and effectively reduce the retention of water, especially in the low-lying areas or dead corners of the pump chamber 110, to prevent residual water from accumulating.

[0050] Combination Figure 7 In some other embodiments of this utility model, the pump chamber 110 is provided with a vent 104, and the air blowing device 20 is connected to the vent 104. Thus, gas can directly enter the pump chamber 110 from the vent, which is beneficial to improve the ventilation or blowing effect. Specifically, the air blowing device 20 can be directly connected to the washing pump 10, so that the air blowing device 20 can be connected to the body of the washing pump 10.

[0051] Furthermore, the drying system 100 includes a check valve 23, which is located between the vent 104 and the blowing device 20 and is configured to allow unidirectional flow in the blowing direction. That is, the connection between the pump chamber 110 and the blowing device 20 can be adjusted via the valve. For example, in conjunction with... Figure 6 The air blowing device 20 is connected to a check valve 23, which is located between the air inlet 104 and the air blowing device 20.

[0052] Combination Figure 2 and Figure 4 In some embodiments of this utility model, the pump chamber 110 includes a first drain outlet 102. An air blowing device 20 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 20 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 20 blows air into the pump chamber 110, it can dry the residual water inside the pump chamber 110 and blow it out. The residual water can be discharged through the first drain outlet 102, thereby achieving the effect of cleaning the washing pump 10. Alternatively, the air blowing device 20 blows 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 continues 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.

[0053] More specifically, a humidity detector can be installed inside the pump chamber 110. The humidity detector transmits signals with the air blowing device 20. When the humidity detector reaches a predetermined value, the air blowing device 20 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 washing appliance.

[0054] Furthermore, combined Figure 1 In some embodiments of this utility model, the washing appliance includes a water cup 30, which can be used to store washing water. When 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.

[0055] In some embodiments of this invention, a first drain port 102 is provided on the pump chamber 110, which can effectively and quickly drain the water inside the pump chamber 110, reducing water retention and accumulation. Combined with the air blowing device 20, it helps to drive the fluid or residual water in the pump chamber 110 to drain out 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, simplifying the structure.

[0056] Combination Figure 4 The first drain outlet 102 can be configured as a long strip extending along the first direction to expand the water outlet range, wherein the first direction is perpendicular to the axial direction of the washing pump 10.

[0057] 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.

[0058] Combination Figure 4 In some embodiments of this utility model, the first drain outlet 102 is connected to the bottom of the pump chamber 110, and the fluid or residual water in the pump chamber 110 easily flows to the first drain outlet 102 by gravity, which is beneficial to improving the drainage effect. Specifically, the 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 20 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.

[0059] Combination Figure 2 The drying system 100 also includes a bypass channel 50, one end of which is connected to the first drain outlet 102, and the other end is connected to a water cup 30. Water discharged from the first drain outlet 102 can flow into the water cup 30 through the bypass channel 50, thus collecting the washing water. The washing water collected in the water cup 30 can either be used for the next washing cycle or discharged through the water cup 30.

[0060] In some embodiments of this utility model, 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.

[0061] In some embodiments of this utility model, 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.

[0062] 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.

[0063] In some embodiments of this utility model, a one-way valve is provided in the bypass channel 50. The one-way valve is configured to allow unidirectional flow from the first drain port 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, combined with... Figure 1The lowest water level in the water cup 30 may be higher than the lowest water level in the washing pump 10. Therefore, in order to prevent water from 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 installed in the bypass channel 30 or the first drain outlet 102 to prevent water from the water cup 30 from flowing back into the pump chamber 110.

[0064] 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.

[0065] Combination Figure 2 In some embodiments of this utility model, 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.

[0066] In some embodiments of this invention, the first connector 12 is located outside the washing pump 10, facilitating connection to the bypass channel 50 or a 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.

[0067] Specifically, in combination 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.

[0068] In some embodiments of this utility model, 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.

[0069] In some embodiments of this utility model, 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.

[0070] 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.

[0071] In some embodiments of this utility model, the first connecting segment and the second connecting segment are constructed with an arc-shaped transition, which can facilitate fluid flow.

[0072] 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.

[0073] Combination Figure 3 and Figure 4 In some embodiments of this utility model, the washing appliance also 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.

[0074] Furthermore, the air blowing device 20 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.

[0075] Furthermore, after the fluid is blown out from the spray device 40, the air blown by the air blowing device 20 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, because the tableware is inside the washing appliance, the water droplets on the surface of the tableware take a long time to dry naturally, and the environment inside the washing appliance is humid, making it even longer to dry naturally and prone to bacterial growth. The air blowing device 20 can dry the washing pump, the spray device, and the tableware.

[0076] Combination Figure 3 According to the drying system 100 of this utility model embodiment, the spraying 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, so that the washing water can be sprayed from different positions or higher positions.

[0077] 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 transported 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 washing appliance, and the second direction can be horizontal or the width of the washing appliance. That is, the main line 41 extends along the height of the washing appliance, 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 washing appliance. For example, the washing appliance can have upper and lower shelves inside the inner tank, 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 washing appliance through the pipeline.

[0078] Furthermore, combining Figure 3The 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 washing appliance. 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, thus improving the cleaning effect.

[0079] Specifically, the first spray arm 431 and the second spray arm 432 can clean the tableware located on the upper part of the washing appliance, while the second spray arm 432 and the third spray arm 433 can be used to clean the tableware located on the lower part of the washing appliance.

[0080] Combination Figure 1 and Figure 3 In some embodiments of this utility model, the drying system 100 further includes a gas distribution valve 60, which has an air inlet 601 and multiple air outlets. A blowing device 20 is connected to the air inlet 601, and one air outlet is connected to the pump chamber 110. The gas distribution valve 60 is configured to selectively connect and disconnect the air outlets from the air inlet 601. Specifically, the multiple air outlets can be connected to different devices or components so that the blowing device 20 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 blowing device 20 flows from the air inlet 601 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.

[0081] Specifically, in combination Figure 1 and Figure 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 20 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.

[0082] The air inlet 601 is connected to the air blowing device 20, so that the gas from the air blowing device 20 can enter the air distribution valve 60 from the air inlet 601. The air distribution valve 60 can send the blown air into the water storage chamber 310 of the water cup 30, or the drainage channel 34, or the washing pump 10.

[0083] More specifically, the air distribution valve 60 can selectively connect or disconnect the air inlet 601 and the air outlet, controlling the connection and disconnection between the air blowing device 20 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 60 can disconnect the air inlet 601 and the air outlet, separating the air blowing device 20 from the pump chamber 110 and preventing the washing water in the pump chamber 110 from entering the air blowing device 20 through the air outlet, thus preventing contamination or damage to the air blowing device 20.

[0084] Optionally, the gas distribution valve 60 can selectively connect the air inlet 601 to one or more of the multiple air outlets. In this way, when the blowing device 20 is working, gas can enter the gas distribution valve 60 from the air inlet 601 and flow out from the multiple air outlets, realizing the gas diversion. This allows gas to be blown to multiple devices at the same time, which helps to improve drying efficiency.

[0085] For example, one of the multiple air outlets can be connected to the water cup 30. When the air distribution valve 60 connects the air inlet 601 to the air outlet, the air blowing device 20 can blow air into the water cup 30, thereby facilitating the drying of the water cup 30.

[0086] Specifically, in combination Figure 2 The drying system 100 also includes a control valve 61, which is connected to and controls the gas distribution valve 60. Thus, the control valve 61 can be used to control one of the multiple gas outlets of the gas distribution valve 60 to be connected to the gas inlet 601 or not connected to the gas inlet 601.

[0087] In some embodiments of this invention, the drying system 100 further includes a heating device. This heating device heats the gas blown out by the air blowing device 20, increasing the airflow temperature and thus improving drying efficiency. Specifically, the heating device can be located within the air blowing device 20, configured to heat the airflow blown by the air blowing device 20 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 20 blows air towards the water cup 30 or the spray device 40, further improving drying efficiency. The heating device can also be used to heat the washing water, thereby increasing its temperature and enabling hot water washing. This provides sterilization and disinfection, and also helps dissolve stains, improving cleaning effectiveness.

[0088] Combination Figure 1In some embodiments of this utility model, the air blowing device 20 includes a fan 21 and an air inlet pipe 22. One end of the air inlet pipe 22 is connected to the fan 21, and the other end blows air towards the air inlet 601 of the pump chamber 110 or the air distribution valve 60. The airflow generated by the fan 21 enters the pump chamber 110 through the air inlet pipe 22, improving the stability of the airflow. Furthermore, the air inlet pipe 22 connecting the fan 21 and the air inlet 601 optimizes the installation position of the fan 21 and improves the space utilization of the washing appliance. For example, the air inlet pipe 22 can be configured as a flexible hose for easy arrangement. For example, the air inlet pipe 22 extends to a certain length, forming an air duct within it.

[0089] In some embodiments of this utility model, the blower 21 is an axial flow blower 21, which makes the structure of the blowing device 20 compact and can provide a larger air volume, making it easier for the blowing device 20 to provide high-speed airflow to the pump chamber 110 and improve the drying efficiency of the pump chamber 110.

[0090] In some embodiments of this utility model, the heating device can be located on the air inlet pipe 22 downstream of the fan 21, so that the air outlet of the fan 21 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 22, which is beneficial to improving the heating effect.

[0091] In some embodiments of this utility model, the blowing device 20 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 20 can only enter the pump chamber 110 in one direction, thereby improving the blowing efficiency of the blowing device 20 and preventing the airflow or water flow in the pump chamber 110 from flowing back into the blowing device 20 when negative pressure is generated, which would affect the service life of the blowing device 20 and improve the reliability of the drying system 100. For example, the blowing device 20 may include a fan 21 and an air inlet pipe 22. The air inlet pipe 22 connects the outlet and the inlet 601 of the fan 21. The one-way valve may be installed at the outlet of the fan 21 or connected to the air inlet pipe 22.

[0092] Combination Figure 1In some embodiments of this utility model, 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 washing appliance 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 receive water, which can be sent to the spray device 40 and sprayed out by the spray arm of the spray device 40.

[0093] More specifically, combined Figure 5 The water distribution chamber 320 is equipped with a first air outlet 321, a second air outlet 322, and a third air outlet 323. The first air outlet 321 connects to the first spray arm 321, the second air outlet 322 connects to the second spray arm 432, and the third air outlet 323 connects to the third spray arm 433. A water distribution valve is installed within the water distribution chamber 320. The water distribution valve can selectively connect or disconnect the air blowing device 20 or the washing pump 10 to 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 to operate depending on the actual situation. Similarly, the water distribution valve can also control the air blowing between the air blowing device 20 and multiple spray arms, allowing the air blowing device 20 to selectively blow air onto one or more spray arms 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.

[0094] Combination Figure 3According to a specific embodiment of the drying system 100 of the utility model, 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 separate channels connecting 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.

[0095] In some embodiments of this utility model, combined with Figure 1 The drying system 100 also includes a drainage device 70. A drain outlet 304 is located at the bottom of the water cup 30, and the drain outlet 304 is connected to the drainage device 70 to drain the 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 air blowing device 20 can also be connected to the water storage chamber 310 of the water cup 30 through the air distribution valve 60, blowing air into the water storage chamber 310 to dry the water cup 30.

[0096] The drying system 100 of a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0097] The drying system 100 is used in washing appliances; the following explanation uses the application of the drying system 100 in a dishwasher as an example. Figures 1 to 5 The drying system 100 includes a washing pump 10 and an air blowing device 20. The air blowing device 20 is connected to the pump chamber 110 of the washing pump 10. The air blowing device 20 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 to circulate back and forth between the water cup 30 and the spray arm. When the washing stops, the drain device 70 drains the water in the dishwasher out of the dishwasher, and the air blowing device 20 also discharges the residual water in the washing pump 10.

[0098] In practical applications, the air blowing device 20 can be installed in the water line of the washing pump 10. The air blowing device 20 can be installed at the front end or upstream (first inlet 101) of the washing pump 10. The connection or connection between the air blowing device 20 and the pump chamber 110 can be adjusted by the air distribution valve 60.

[0099] 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.

[0100] The air blowing device 20 is located 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 20 will continue to work until the pump chamber 110 is dry. There is a valve on the air duct of the air blowing device 20 to control the connection or disconnection of the air blowing device 20 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, and the residual water in the washing pump 10 is also drained. After draining, the fan 21 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.

[0101] The washing appliance according to the present invention includes the aforementioned drying system 100. By providing the aforementioned drying system 100 in the washing appliance, the air blowing device 20 can blow air onto the washing pump 10 to dry the washing pump 10. This can prevent 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 thus improving the cleaning effect of the cleaning equipment.
