[0032] Water cup assembly 100, water cup 10, chamber 11, water outlet 12, air outlet 13, air blowing device 20, fan 21, air inlet pipe 22, filter element 30, cylindrical filter screen 31, rotating shaft 311, cup lifting 32, drain pump 40, check valve 41, washing pump 50, air distribution valve 60. Detailed Implementation

[0033] 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.

[0034] The water cup assembly 100 according to an embodiment of the present invention can be used in a dishwasher.

[0035] Combination Figure 1The water cup assembly 100 includes a water cup 10 and an air blowing device 20. The water cup 10 has a chamber 11, a water inlet, a water outlet 12, and an air blowing port 13, which are connected to the chamber 11. The air blowing device 20 is connected to the air blowing port 13 for blowing air into the chamber 11. Specifically, water can be introduced into the water cup 10 through the inlet. After entering the water cup 10, the water flows to components such as the spray arm according to a predetermined path. The outlet 12 can discharge the water in the water cup 10. After the dishwasher completes one washing cycle, the water in the water cup 10 is discharged from the outlet 12. After the dishwasher finishes washing, the water cup 10 usually contains residual water. By setting an air blowing device 20 to blow air into the chamber 11, the air blowing device 20 provides positive pressure to the chamber 11, which can accelerate the flow of residual water in the water cup 10, remove the residual water in the water cup 10, and accelerate the evaporation of water in the water cup 10, thereby drying the chamber 11 and preventing residual water from accumulating in the chamber 11 and breeding bacteria and producing odors. In addition, the chamber 11 is provided with an air blowing port 13, and the air blowing device 20 is connected to the air blowing port 13, which can improve the efficiency of the air blowing device 20 to blow air into the chamber 11, thereby improving the drying efficiency of the chamber 11.

[0036] The water cup assembly 100 also includes a filter element 30, at least a portion of which is disposed in the chamber 11. At least a portion of the airflow from the air outlet 23 is directed toward the filter element 30. Specifically, the filter element 30 is used to filter food residue on tableware. During a dishwasher cycle, water circulates to clean the tableware, and food residue on the tableware enters the filter element 30 along with the water flow. The filter element 30 filters the water flow, preventing residue from entering the dishwasher's water pump, spray arms, and other components, thus improving the dishwasher's cleaning efficiency. After filtration, the surface of the filter element 30 usually retains moisture. At least a portion of the airflow from the air outlet 23 is directed toward the filter element 30, which can dry the filter element 30 and prevent the residual moisture on the filter element 30 from breeding bacteria and producing odors after long-term storage, thus avoiding secondary pollution.

[0037] In this embodiment, at least a portion of the airflow from the air outlet 23 is directed toward the filter element 30. For example, part of the airflow from the air outlet 23 is directed toward the filter element 30, and another part is directed toward the inner circumferential surface of the water cup 10, so that the airflow from the air blowing device 20 can simultaneously dry the filter element 30 and the water cup 10, thereby improving the drying effect on the water cup assembly 100. Alternatively, all the airflow from the air outlet 23 can be directed toward the filter element 30. The concentrated airflow from the air outlet 23 directed toward the filter element 30 can improve the drying efficiency of the filter element 30 and also clean the residue attached to the filter element 30. Of course, in the embodiment where all the airflow is directed toward the filter element 30, since the surface of the filter element 30 has filter holes, the airflow can still pass through the filter element 30 and circulate in the chamber 11 to dry the wall surface of the chamber 11.

[0038] In addition, at least a portion of the filter element 30 is disposed in the chamber 11, or the entire filter element 30 may be disposed in the chamber 11; or, a portion of the filter element 30 may be disposed in the chamber 11, and the other portion may extend out of the chamber 11. For example, the filter element 30 may include a cup 32, the upper end of which is provided with a handle that extends out of the chamber 11, making it convenient for the user to remove the filter element 30 for cleaning and maintenance.

[0039] According to the embodiment of the present invention, the water cup assembly 100 can remove residual water in the water cup 10 by blowing air into the chamber 11 of the water cup 10 through the air blowing device 20, and dry the water cup 10 and the filter element 30, so as to prevent residual water from accumulating in the water cup 10 and the filter element 30 and causing bacteria growth and odor.

[0040] The air blowing device 20 is used to blow air into the chamber 11 of the water cup 10 to provide positive pressure to the chamber 11. For example, the air blowing device 20 can be an air pump or a fan.

[0041] Additionally, the water cup 10 has an air outlet 13 connecting to the chamber 11. The air outlet 13 can be separately provided on the water cup 10 to allow air to be blown into the chamber 11 via the air blowing device 20. For example, the air blowing device 20 or the air outlet 13 may be equipped with a valve plate, which is configured to be unidirectionally open in the air blowing direction. That is, the airflow from the air blowing device 20 can be directed towards the chamber 11, but the fluid in the chamber 11 cannot enter the air blowing device 20. Alternatively, the air outlet 13 can be an interface connecting the water cup 10 to the washing pump 50, meaning that the air blowing device 20 can direct airflow into the chamber 11. The air blowing interface of chamber 11 and the water supply interface of water cup 10 to washing pump 50 are the same interface. Specifically, when washing pump 50 is working, it drives the water in water cup 10 to flow out from air blowing port 13 and into washing pump 50, and then into the spray arm of dishwasher, and sprayed out from the spray arm to clean tableware, etc. The air blowing port 13 of water cup 10 and the interface of water cup 10 and washing pump 50 are shared, which can simplify the structure of water cup assembly 100 and optimize the space utilization of water cup assembly 100. For example, air blowing device 20 can be connected to the tube between water cup 10 and washing pump 50.

[0042] Combination Figure 3 In some embodiments of this utility model, the air outlet 13 has a flat outlet extending in the vertical direction. The airflow blown out by the air blowing device 20 is accelerated and relatively concentrated after passing through the air outlet 13, thereby improving the drying efficiency of the chamber 11. Combined with... Figure 3As shown, the arrows indicate the direction of the airflow from the air outlet 13. The air outlet 13 is flat and extends vertically, allowing the airflow to disperse upwards and downwards, increasing the coverage of the chamber 11 in the vertical direction and improving the drying effect on the chamber 11. For example, the water cup 10 may have a bottom wall and a peripheral wall surrounding the bottom wall. The air outlet 13 may be located on the peripheral wall, and the chamber 11 is used to house the filter element 30. By setting the air outlet 13 as a flat outlet extending vertically, the height of the airflow from the blowing device 20 covering the filter element 30 can be increased, thereby improving the drying efficiency of the filter element 30.

[0043] Combination Figure 4 In some embodiments of this utility model, the water cup assembly 100 further includes a drain pump 40, which is connected to a water outlet 12. The water outlet 12 and the air blowing port 13 are distributed on opposite sides of the chamber 11. Specifically, after the dishwasher completes a washing cycle, the water in the water cup 10 can be drained by the drain pump 40. The air blowing port 13 is located on the opposite side of the water outlet 12. On the one hand, it facilitates the blowing of residual water in the water cup 10 towards the water outlet 12 by the air blowing device 20, thereby improving the drying efficiency of the chamber 11. Also, some of the airflow entering the chamber 11 can be discharged from the water outlet 12. On the other hand, it optimizes the layout of the water cup assembly 100, making it easier to install and compactly design the water cup assembly 100.

[0044] For example, the drain pump 40 is provided with a drain pump chamber, which is connected to the water outlet 12 and the drain pipe respectively. When the air blowing device 20 is working, the airflow enters the chamber 11 through the air blowing port 13. The residual water in the chamber 11 can enter the drain pump chamber through the water outlet 12 under the action of positive pressure and be discharged into the drain pipe, so as to avoid the accumulation of residual water in the water cup 10 and improve the drying efficiency of the chamber 11.

[0045] In addition, the drain pump chamber is connected to the drain pipe, and the outlet of the drain pump chamber can be connected to a check valve 41 to prevent backflow of water and air in the drain pipe, so as to maintain a good working environment within the water cup assembly 100.

[0046] Combination Figure 5Optionally, the lower end of the air outlet 13 is connected to the bottom wall of the water cup 10, and the height H1 of the upper end of the air outlet 13 from the bottom wall of the water cup 10 satisfies: 20mm ≤ H1 ≤ 40mm. Specifically, residual water tends to accumulate on the bottom wall of the water cup 10, and connecting the lower end of the air outlet 13 to the bottom wall of the water cup 10 facilitates drying the residual water in the chamber 11. In addition, the height of the upper end of the air outlet 13 from the bottom wall of the water cup 10 is greater than or equal to 20mm to avoid the air outlet 13 being too small, resulting in insufficient coverage of the chamber 11 and the filter element 30, which would affect the drying effect on the chamber 11 and the filter element 30; the height of the upper end of the air outlet 13 from the bottom wall of the water cup 10 is less than or equal to 40mm to avoid the air outlet 13 being too high, which would affect the intensity of the airflow from the air outlet 13, thereby affecting the drying efficiency of the chamber 11 and the filter element 30, and also ensures the structural strength of the water cup 10. For example, a filter element 30 can be placed in the chamber 11, and the distance between the air outlet 13 and the bottom wall of the water cup 10 is set within a reasonable range so that the airflow blown out by the air outlet 13 can reasonably cover the filter element 30 and ensure the strength of the airflow blown out by the air outlet 13, thereby improving the drying effect on the chamber 11 of the water cup 10 and the filter element 30.

[0047] For example, the height H1 of the upper end of the air outlet 13 from the bottom wall of the water cup 10 can be 25mm, 28mm, 30mm, 31mm, 33mm, 35mm, etc. By setting the air outlet 13 in a suitable position in the water cup 10, the drying effect and drying efficiency of the chamber 11 and the filter element 30 can be improved.

[0048] Combination Figure 8 For example, the filter element 30 may include a cup 32 and a cylindrical filter screen 31, with the cup 32 inserted into the cylindrical filter screen 31.

[0049] Combination Figure 3 Optionally, the blowing device 20 is configured to blow air tangentially to the water cup 10. The airflow direction is tangential to the inner wall of the water cup 10, rather than perpendicular or axial, so that the airflow from the blowing device 20 enters the chamber 11 and flows tangentially to the chamber 11, forming a rotating airflow within the chamber 11. This increases the contact area between the airflow and the chamber 11, thereby improving the drying efficiency of the chamber 11. Additionally, a filter element 30 is provided within the chamber 11 to further increase the contact area between the airflow and the filter element 30, improving the drying effect on the filter element 30.

[0050] Furthermore, in related technologies, dishwashers require manual cleaning and wiping of the filtration system (filter screen, etc.) after a period of use to maintain its cleanliness. Manual cleaning places certain demands on the user and negatively impacts the user experience. In this embodiment, the air blowing device 20 of the water cup assembly 100 blows air onto the filter screen, which can also remove residue adhering to the surface of the filter element 30, achieving self-cleaning of the filter element 30 and avoiding additional user intervention.

[0051] Combination Figure 7 In some embodiments of this utility model, the filter element 30 includes a cylindrical filter screen 31, which is rotatably disposed in the chamber 11. The air blowing device 20 is configured to blow air tangentially to the cylindrical filter screen 31. The air blowing device 20 is configured to allow air to enter tangentially to the cylindrical filter screen 31, in conjunction with the attached... Figure 7 As shown, the arrow indicates the airflow direction. The airflow direction is tangential to the wall of the cylindrical filter 31, allowing the airflow to be sprayed onto one side of the cylindrical filter 31, rather than entering vertically or axially. This provides a rotational driving force for the cylindrical filter 31, enabling it to rotate in the direction indicated by the arrow. When the airflow hits the surface of the cylindrical filter 31, residues can be separated from it. Since the cylindrical filter 31 is rotating, the airflow is prevented from only hitting a local area of ​​the cylindrical filter 31, thus ensuring that the cylindrical filter 31 is cleaned from all angles.

[0052] In addition, combined Figure 6 The arrows indicate the flow direction of circulating water during the dishwasher's operation. During operation, water before filtration enters from the inside of the cylindrical filter screen 31, and water after filtration flows out from the outside of the cylindrical filter screen 31. Therefore, food residue and other dirt usually adhere to the inside of the cylindrical filter screen 31. Airflow blows from the air outlet 13 towards the cylindrical filter screen 31, that is, airflow blows from the outside of the cylindrical filter screen 31 to the inside. This makes it easier to peel off the residue attached to the inside of the cylindrical filter screen 31, allowing the residue to fall to the bottom of the water cup 10 so that the residue can be discharged from the dishwasher. This achieves self-cleaning of the cylindrical filter screen 31 and improves the cleaning efficiency of the cylindrical filter screen 31.

[0053] The cylindrical filter screen 31 may have a first filter section at its lower part and a second filter section on its peripheral wall, wherein the mesh size of the first filter section is smaller than that of the second filter section. Specifically, the air blowing device 20 blows air toward the second filter section to facilitate the removal of residues adhering to the inner surface of the second filter section. Since the mesh size of the first filter section is smaller than that of the second filter section, it is easier for the residues removed from the second filter section to be discharged from the first filter section, thereby improving the cleaning efficiency of the filter element 30.

[0054] For example, the air blowing device 20 may include a fan 21, which can provide high-pressure airflow to the chamber 11. The high-pressure airflow blown by the air blowing device 20 directly reaches the chamber 11 of the water cup 10. On the one hand, it can remove residual water in the chamber 11 and dry the chamber 11 and the cylindrical filter screen 31. The high-pressure airflow blows along the tangential direction of the cylindrical filter screen 31, which can drive the cylindrical filter screen 31 to rotate, making it easier to clean various parts of the cylindrical filter screen 31. During the rotation, the cylindrical filter screen 31 will generate centrifugal force, which makes it easier for residues to be removed from the cylindrical filter screen 31, realizing the self-cleaning of the cylindrical filter screen 31. This maintains a dry and clean environment inside the water cup assembly 100, preventing residual water, residues, etc. from accumulating inside the water cup assembly 100 and breeding bacteria.

[0055] Additionally, the cylindrical filter screen 31 is rotatably disposed in the chamber 11. For example, the filter element 30 may also include a filter support, which is installed within the chamber 11 of the water cup 10. The lower end of the filter support may have a shaft hole. The cylindrical filter screen 31 is rotatably disposed on the filter support, simplifying the structure of the filter element 30 and making its structure more compact. The cylindrical filter screen 31 may include a filter body and a rotating shaft 311. The upper end of the rotating shaft 311 is fixedly connected to the lower end of the filter body, and the lower end of the rotating shaft 311 fits into the shaft hole, improving the stability of the cylindrical filter screen 31 during rotation.

[0056] Optionally, the cylindrical filter screen 31 is cylindrical, and the axis of the rotating shaft 311 coincides with the axis of the rotating shaft 311 of the cylindrical filter screen 31.

[0057] In some embodiments of this utility model, the water cup assembly 100 has a first working mode. In the first working mode, the air blowing device 20 blows air from the outside of the cylindrical filter screen 31 to the cylindrical filter screen 31 and drives the cylindrical filter screen 31 to rotate, so as to peel off the dirt on the inside of the cylindrical filter screen 31. Specifically, the airflow blown by the air blowing device 20 blows from the air blowing port 13 to the cylindrical filter screen 31. The airflow blows from the outside of the cylindrical filter screen 31 to the inside, so it is easier to peel off the residue attached to the inside of the cylindrical filter screen 31. The air blowing device 20 drives the cylindrical filter screen 31 to rotate, which facilitates air blowing to various parts of the cylindrical filter screen 31. Moreover, the cylindrical filter screen 31 generates centrifugal force during rotation, which makes it easier for the residue to detach from the cylindrical filter screen 31, thereby realizing the self-cleaning of the cylindrical filter screen 31.

[0058] The water cup assembly 100 also has a second operating mode, in which water enters the chamber 11 through the inlet and drains through the outlet 12. This allows for the injection of clean water into the chamber 11 through the inlet, followed by drainage, facilitating the cleaning of the cylindrical filter screen 31 and the water cup 10.

[0059] Furthermore, the first and second working modes operate in a sequential cycle, with the number of cycles N≥2. For example, a self-cleaning program can be preset in the dishwasher, or a self-cleaning program can be added after the dishwasher's washing program. The first working mode is started first, followed by the second working mode, and the first and second working modes are cycled multiple times in sequence, which can improve the self-cleaning effect on the filter. Specifically, the dishwasher can first control the air blowing device 20 to blow air onto the filter element 30, then inject clean water into the water cup 10, then start draining, and repeat this cycle several times. The air blowing device 20 blows air from the outside of the cylindrical filter 31 to the inside of the cylindrical filter 31 and drives the cylindrical filter 31 to rotate, which can peel off dirt from the inside of the cylindrical filter 31. Then, clean water is injected into the water cup 10, and draining is started, which can clean the cylindrical filter 31 and the water cup 10. During the draining process, the peeled residue can be discharged, improving the self-cleaning effect.

[0060] In addition, after the aforementioned self-cleaning process is completed, the air blowing device can blow air into the chamber again to dry the water cup and filter. In other words, after the self-cleaning mode is completed, the dishwasher can also preset a drying mode to keep the water cup assembly in a dry environment and prevent bacteria from growing in the dishwasher for a long time.

[0061] In some embodiments of this utility model, the air blowing device 20 is connected to a one-way valve. The one-way valve is configured to be unidirectionally open in the air blowing direction. That is, under the action of the one-way valve, the airflow blown out by the air blowing device 20 can only enter the chamber 11 in one direction, thereby improving the air blowing efficiency of the air blowing device 20 and preventing the airflow or water flow in the chamber 11 from entering the air blowing device 20 in the reverse direction when the chamber 11 generates negative pressure, which would affect the service life of the air blowing device 20 and improve the reliability of the water cup assembly 100.

[0062] For example, the air blowing device 20 may include a fan 21 and an air inlet pipe 22, the air inlet pipe 22 being connected to the outlet and inlet of the fan 21, and a one-way valve may be installed at the outlet of the fan 21 or connected to the air inlet pipe 22.

[0063] In some embodiments of this utility model, the water cup assembly 100 further includes a heating element configured to heat the airflow blown by the air blowing device 20 towards the chamber 11, making the airflow entering the chamber 11 a hot airflow, accelerating the evaporation efficiency of residual water in the chamber 11, thereby improving the drying efficiency of the chamber 11 and maintaining a dry environment in the chamber 11. Exemplarily, the heating element may be located downstream of the fan 21; or, the heating element may be located on the air inlet pipe 22 to heat the airflow blown by the fan 21.

[0064] Combination Figure 8In some embodiments of this utility model, the air blowing device 20 includes a fan 21 and an air inlet pipe 22. The air inlet pipe has a first end and a second end, the first end of which is connected to the fan 21, and the second end is connected to the air blowing port for blowing air toward the chamber 11. The airflow generated by the fan 21 enters the chamber 11 through the air inlet pipe 22, improving the stability of the airflow. In addition, the air inlet pipe 22 connects the fan 21 and the air blowing port 13, which can optimize the installation position of the fan 21 and improve the space utilization of the dishwasher. For example, the air inlet pipe 22 can be configured as a flexible hose.

[0065] In some embodiments of this utility model, the blower 21 is an axial flow blower, 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 chamber 11 and improve the drying efficiency of the chamber 11.

[0066] Combination Figure 7 In some embodiments of this utility model, the water cup assembly 100 further includes an air distribution valve 60, which has an air inlet, a first outlet and a second outlet. The air blowing device 20 is connected to the air inlet, and the first outlet is connected to the air blowing port 13. The water cup assembly 100 also includes a washing pump 50, and the second outlet is connected to the water inlet of the washing pump 50.

[0067] For example, the air distribution valve 60 may include a housing and an air distribution component. The housing has a cavity, and an air inlet, a first outlet, and a second outlet are disposed in the housing. The air distribution component is disposed in the cavity and has a first connected state, a second connected state, and a closed state. In the first connected state, the air distribution component controls the first outlet to connect to the air inlet. In the second connected state, the air distribution component controls the second outlet to connect to the air inlet. In the closed state, the air distribution component controls the first outlet and the second outlet to disconnect from the air inlet, and the first outlet and the second outlet are connected.

[0068] Specifically, the air blowing device 20 introduces airflow into the air distribution valve 60 through the air inlet, and controls the direction of the airflow through the air distribution component. In the first connected state, the air distribution component controls the airflow blown by the air blowing device 20 to flow towards the water cup 10 to remove residual water in the water cup 10 and dry the water cup 10 and the filter element 30. In the second connected state, the air distribution component controls the airflow blown by the air blowing device 20 to flow towards the washing pump 50 to remove residual water in the washing pump 50 and dry the washing pump 50. By setting the air distribution component, it is convenient to distribute the airflow blown by the air blowing device 20 to different components through the air distribution valve 60.

[0069] In addition, the air distribution component also has a cut-off state. In the cut-off state, the first outlet is disconnected from the air inlet, the second outlet is disconnected from the air inlet, and the first and second outlets are connected. That is, in the cut-off state, the first and second outlets are connected and both are disconnected from the air blowing device 20. At this time, the water cup 10 can be connected to the washing pump 50 through the air blowing port 13. In other words, the air blowing port 13 is also the interface for the water cup 10 to connect to the washing pump 50. The interface for the air blowing device 20 to blow air into the chamber 11 and the interface for the water cup 10 to supply water to the washing pump 50 are the same interface. Specifically, when the washing pump 50 is working, it drives the water in the water cup 10 to flow out from the air blowing port 13, enter the washing pump 50 through the water supply pipe, and then enter the spray arm of the dishwasher. It is sprayed out from the spray arm to clean the tableware, etc. The air blowing port 13 of the water cup 10 and the interface between the water cup 10 and the washing pump 50 are shared, which can simplify the structure of the water cup assembly 100 and optimize the space utilization of the water cup assembly 100.

[0070] The air distribution valve 60 is connected between the water cup 10 and the washing pump 50. The air blowing device 20 can blow air into the washing pump 50 through the air distribution valve 60, which can remove residual water in the washing pump 50 and dry it, so as to prevent residual water from accumulating in the washing pump 50 and affecting the washing pump 50.

[0071] Combination Figure 2 In some embodiments of this utility model, the water cup assembly 100 further includes a drain pump 40. Specifically, the drain pump 40 can be connected to the water cup 10 and is used to drain the washing water inside the water cup 10.

[0072] The air distribution valve 60 may also have a third outlet, which is connected to the drain pump 40. Exemplarily, the third outlet may be located in the housing of the air distribution valve 60.

[0073] Specifically, the air blowing device 20 is connected to the air inlet and is used to introduce positive pressure airflow into the air distribution valve 60. The airflow is then distributed to the water cup 10, washing pump 50, and drain pump 40 through the air distribution valve 60. This positive pressure airflow drives the removal of residual water from the water cup 10, washing pump 50, and drain pump 40, accelerating the evaporation of this residual water and drying them. Understandably, after the dishwasher completes its washing cycle, the water cup 10, washing pump 50, and drain pump 40 will typically contain residual water. By introducing airflow into these components through the air blowing device, the residual water can be removed and dried, preventing the residual moisture from breeding bacteria and producing odors after prolonged storage, thus avoiding secondary contamination of the tableware.

[0074] For example, the air distribution valve 60 also includes a partition plate, which is disposed in the inner cavity and separates the air inlet cavity and the air outlet cavity. The air inlet is disposed in the wall of the air inlet cavity, and the first outlet, the second outlet and the third outlet are disposed in the wall of the air outlet cavity. The partition plate is provided with a first connecting hole.

[0075] The air distribution valve 60 also includes an air distribution block, which is rotatably disposed in the air outlet chamber and has a second connecting hole. The air distribution block has a cut-off position and a connecting position. In the connecting position, the second connecting hole is connected to the first connecting hole to connect the air inlet chamber and the air outlet chamber. In the cut-off position, the second connecting hole is disconnected from the first connecting hole to separate the air inlet chamber and the air outlet chamber. In the cut-off position, the air distribution block closes the first outlet and opens the second and third outlets.

[0076] Specifically, an air inlet chamber and an air outlet chamber are separated within the inner cavity by a partition plate. An air distributor works in conjunction with the partition plate. In the connected position, the second connecting hole connects with the first connecting hole, allowing the air inlet chamber to receive air. The air outlet chamber, in conjunction with the air distributor, distributes fluid to different outlets. In the closed position, the second connecting hole disconnects from the first connecting hole, separating the air inlet chamber from the air outlet chamber. In other words, the three outlets are disconnected from the air inlet. At this time, the first and second outlets are connected, and the air distributor closes the third outlet, allowing the water cup 10 to connect with the washing pump 50, facilitating the entry of water from the water cup 10 into the washing pump 50. During normal washing in the dishwasher, the air distributor can switch to the closed state, connecting the first and second outlets and disconnecting from the air inlet, allowing the washing pump 50 to drive water from the water cup 10 into the spray arm. After the dishwasher completes the washing process, the air distributor can switch to the connected state, allowing airflow to be introduced into the water cup 10, washing pump 50, and drain pump 40 via the air blowing device 20.

[0077] In addition, the air distribution block may have multiple connected positions. In the connected positions, at least one of the first outlet, the second outlet and the third outlet is controlled to connect the air outlet chamber, so as to distribute the airflow blown by the air blowing device 20 to different components according to the actual use requirements.

[0078] This utility model also provides a dishwasher, including a main body and the aforementioned water cup assembly 100. The main body is provided with a washing chamber, and the water cup assembly 100 is connected to the washing chamber. By setting the aforementioned water cup assembly 100, the air blowing device 20 provides positive pressure to the chamber 11, which can drive the residual water in the water cup 11 to be discharged using positive pressure airflow, and can accelerate the evaporation of residual water in the chamber 11 and the filter element 30 in the water cup 10, thereby drying the chamber 11 and the filter element 30 and preventing residual water from accumulating in the water cup 10 and causing bacteria growth and odor.
