[0041] This application discloses a dishwasher, combined with Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the dishwasher includes a water cup device 1000, a spray device 2000, an air blowing device 3000, and a diverting device 4000. The air blowing device 3000 is used to pump airflow to the water cup device 1000 and the spray device 2000. The diverting device 4000 is connected to the water cup device 1000, and the water cup device 1000 is connected to the spray device 2000 through the diverting device 4000. The air blowing device 3000 is connected to the diverting device 4000. The diverting device 4000 is used to control at least one of the water cup device 1000 and the spray device 2000 to be connected to the air blowing device 3000, so that at least one of the water cup device 1000 and the spray device 2000 receives the airflow pumped by the air blowing device 3000.

[0042] The dishwasher can control the airflow pumped by the air blowing device 3000 to blow the airflow of the water cup device 1000 and the spray device 2000 to at least one of them, thereby targeting and drying the water cup device 1000 and the spray device 2000, effectively improving the drying effect and preventing bacteria from growing in the water cup device 1000 and the spray device 2000 due to the presence of residual water.

[0043] The dishwasher will be described in detail below. Generally, a dishwasher includes an inner tub (not shown in the figure), a dish rack (not shown in the figure), a water cup holder 1000, a spray device 2000, a circulation pump 5000, and a drain pump 6000.

[0044] The inner tub has a washing chamber (i.e., the internal space of the inner tub) and an opening that communicates with the washing chamber. The dishwasher door can move between the open position and the closed position. When the door moves to the closed position, the opening is closed. When the door moves to the open position, the opening is opened.

[0045] The dish rack is installed inside the dishwasher and can slide in and out of the washing chamber for easy loading and unloading of tableware. The dish rack is usually perforated to allow water to pass through and rinse the tableware. Tableware should be understood as any items that can be washed by a dishwasher, including but not limited to bowls, plates, cups, pots, knives, forks, and chopsticks.

[0046] The spray device 2000 is used to spray water towards the washing chamber. The water is directed at the dishes to rinse and clean them. That is, during the washing cycle of the dishwasher, water needs to be sprayed through the spray device 2000 to clean the dishes. There are various types of spray devices 2000. The spray device 2000 can be movable, moving while spraying water to enhance the rinsing of the dishes. The spray device 2000 can also be fixed, so that water can be sprayed at a fixed angle.

[0047] The spraying water flow from the spray device 2000 is achieved through the operation of the circulation pump 5000. The circulation pump 5000 is a key component for realizing the washing cycle. The circulation pump 5000 is connected to the water cup device 1000, which is located at the bottom of the inner tank for temporary water collection and storage. The circulation pump 5000 draws water from the water cup device 1000 and delivers it to the spray device 2000. The water flow sprays out from the spray device 2000 and rinses the tableware before falling back to the bottom of the inner tank and then flowing back into the water cup device 1000, where it is drawn in again by the circulation pump 5000. This forms a washing cycle to rinse and clean the tableware.

[0048] After the dishwasher finishes its washing cycle, it needs to drain the water. This is achieved by the operation of the drain pump 6000, which is connected to the water cup device 1000. When the drain pump 6000 is started, it can drain the water in the water cup device 1000.

[0049] After draining, dishwashers need to dry the food, and there are several drying methods available. For example, automatic door drying involves the dishwasher opening the door during drying, creating convection current between hot air inside the drum and cold air outside. Because hot air is less dense than cold air, it rises and escapes from the drum, while cold air enters, quickly removing moisture and drying the dishes. Another method is hot air drying, where heated air is introduced into the drum, which also has an exhaust vent. The hot air is then expelled from the vent, removing moisture from the drum and simultaneously heating the dishes, accelerating the drying process.

[0050] As can be seen from the above, most current dishwashers dry the inner tub and thus the dishes. Because the spray device 2000 needs to spray water, its nozzles are relatively small, which fails to effectively remove moisture from inside the spray device 2000, leaving residual water inside. Furthermore, since the water cup device 1000 is located at the bottom of the inner tub and has a cavity for collecting and storing water, and especially since this cavity typically also houses a filter (not shown in the figure) to filter impurities, the aforementioned drying method is also insufficient for effectively drying the water cup device 1000. Therefore, this embodiment uses an air blowing device 3000 in conjunction with a flow diversion device 4000 to achieve a certain degree of drying for the spray device 2000 and / or the water cup device 1000, reducing or even eliminating residual water in these devices.

[0051] The air blowing device 3000 is connected to the spraying device 2000. The air blowing device 3000 can pump airflow into the spraying device 2000, that is, the air blowing device 3000 can deliver airflow into the interior of the spraying device 2000. The airflow can remove the moisture inside the spraying device 2000, thereby drying the spraying device 2000 and preventing the accumulation of residual water inside the spraying device 2000, which would breed bacteria. The airflow sprayed out from the spraying device 2000 can enter the inner liner to dry the tableware. In addition, the air blowing device 3000 is also connected to the water cup device 1000. The air blowing device 3000 can pump airflow into the water cup device 1000, that is, the air blowing device 3000 can deliver airflow towards the interior of the water cup device 1000. The airflow can remove moisture from the interior of the water cup device 1000, thus drying the water cup device 1000 and preventing the accumulation of residual water inside the water cup device 1000, which would then breed bacteria. The airflow sprayed out from the water cup device 1000 can enter the inner liner, achieving the drying of the tableware. It can be understood that the air blowing device 3000 is used to realize the pumping of airflow; that is, the air blowing device 3000 includes fluid machinery, which provides the power required for pumping airflow. The fluid machinery includes, but is not limited to, a fan.

[0052] In this embodiment, the dishwasher further includes a diversion device 4000, which is connected to the water cup device 1000 and the water cup device 1000 is connected to the spray device 2000 via the diversion device 4000. An air blowing device 3000 is connected to the diversion device 4000. The diversion device 4000 is adapted to control at least one of the water cup device 1000 and the spray device 2000 to connect to the air blowing device 3000, thereby allowing at least one of the water cup device 1000 and the spray device 2000 to receive the airflow pumped by the air blowing device 3000. When the diversion device 4000 controls the water cup device 1000 to connect to the air blowing device 3000, the airflow pumped by the air blowing device 3000 is delivered to the water cup device 1000, thereby removing moisture from the water cup device 1000 and reducing or even eliminating the formation of residual water in the water cup device 1000. When the diversion device 4000 controls the spray device 2000 to connect with the air blowing device 3000, the airflow pumped by the air blowing device 3000 is delivered to the spray device 2000, thereby removing the moisture from the spray device 2000 and reducing or even eliminating the formation of residual water in the spray device 2000.

[0053] The dishwasher can more effectively dry the air blowing device 3000 and / or the water cup device 1000 according to actual needs through the control of the diversion device 4000, adapting to multiple drying modes. For example, the diversion device can simultaneously control the air blowing device 3000, the water cup device 1000, and the spray device 2000 to connect, thereby synchronously pumping airflow to the air blowing device 3000 and the water cup device 1000 to remove moisture from the water cup device 1000 and the spray device 2000.

[0054] Combination Figure 4 and Figure 5 As shown, in some embodiments, the water cup device 1000 is provided with a water receiving cavity 1100, which is open upwards and suitable for receiving washing water to temporarily store the washing water. When the diversion device 4000 controls the air blowing device 3000 to connect with the water cup device 1000, the air blowing device 3000 can pump airflow into the water receiving cavity 1100.

[0055] The orientation in this article is based on the dishwasher being installed and in use. The side of the dishwasher closest to the ground is the bottom, and the side away from the ground is the top. The water cup device 1000 is located at the bottom of the inner tub, and the water receiving chamber 1100 is open upwards, thus communicating with the washing chamber of the inner tub. Water flows into the water receiving chamber 1100 under the action of gravity, and is then drawn by the circulation pump 5000 and delivered to the spray device 2000. Generally, the dishwasher also includes a filter device, which is connected to the water cup device 1000 and located in the water receiving chamber 1100. This filter device is used to filter impurities in the water flow, preventing impurities from clogging the circulation pump 5000 and the spray device 2000. The water receiving cavity 1100 is a concave space. In order to accommodate the installation of the filter device and the connection of other components, the cavity wall of the water receiving cavity 1100 is not regular but irregular, which makes it easy for residual water to remain. The airflow pumped by the air blowing device 3000 to the water cup device 1000 is specifically directed to the water receiving cavity 1100. The airflow pumped by the air blowing device 3000 carries away the moisture in the water receiving cavity 1100, thereby drying the water cup device 1000. When the filter device is present in the water receiving cavity 1100, the airflow can also carry away the moisture of the filter device, thereby drying the filter device and preventing the growth of bacteria.

[0056] Combination Figure 4 and Figure 5 and Figure 6 As shown, in some embodiments, the diversion device 4000 includes a water cup outlet 4110. When the diversion device 4000 controls the air blowing device 3000 to connect with the water cup device 1000, the airflow pumped by the air blowing device 3000 is suitable to enter the water receiving chamber 1100 through the water cup outlet 4110, thereby taking away the water in the water receiving chamber 1100.

[0057] For example, the diverter 4000 can control the opening and closing of the water cup outlet 4110. When the diverter 4000 controls the water cup outlet 4110 to open, the air blowing device 3000 and the water cup device 1000 are connected. The airflow pumped by the air blowing device 3000 enters the diverter 4000 and flows out of the water cup outlet 4110, thus entering the water receiving chamber 1100. When the diverter 4000 controls the water cup outlet 4110 to close, the air blowing device 3000 and the water cup device 1000 are disconnected.

[0058] Combination Figure 4 and Figure 5 As shown, in some embodiments, the water cup device 1000 is provided with an air outlet 1200 communicating with the water cup outlet 4110. The water cup outlet 4110 is open towards the water receiving cavity 1100, so that the airflow flowing out of the water cup outlet 4110 will flow towards the water receiving cavity 1100, reducing the loss of airflow before entering the water receiving cavity 1100, which helps to improve the drying efficiency of the water cup device 1000.

[0059] Optionally, combined Figure 4 and Figure 5 As shown, in some embodiments, the air outlet 1200 is exposed above the wall of the water receiving chamber 1100, so that airflow can be directly output to the water receiving chamber 1100. In particular, when the filter device is installed in the water receiving chamber 1100, part of the airflow output from the air outlet 1200 can enter the gap between the filter device and the water receiving chamber 1100 and take away the moisture in the water receiving chamber 1100. The other part of the airflow can pass through the filter device and take away the moisture in the filter device. This helps to improve the drying efficiency of the water cup device 1000 and the filter device.

[0060] Combination Figure 7 As shown, in some embodiments, the air outlet 1200 is flat in the vertical direction, which is beneficial for the diffusion of air. Optionally, the water cup device 1000 also includes an air guide 1300, which is connected to the water receiving cavity 1100. The air guide 1300 is provided with the air outlet 1200. By providing the air guide, it is more conducive to the formation of the flat air outlet 1200.

[0061] Combination Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the diversion device 4000 includes a housing 4100 and a valve core 4200. The housing 4100 is provided with a diversion chamber 4130. The valve core 4200 is movably disposed in the diversion chamber 4130 so as to open and close the water cup outlet 4110. The air blowing device 3000 is connected to the diversion chamber 4130, and the water receiving chamber 1100 is connected to the water cup outlet 4110. When the valve core 4200 opens the water cup outlet 4110, the diversion chamber 4130 is connected to the water cup outlet 4110.

[0062] The valve core 4200 can move in various ways, including but not limited to rotation, reciprocating movement, extension, and deformation. The movement of the valve core 4200 can be driven by a motor. Controlling the movement of the valve core 4200 under appropriate conditions allows for the opening and closing of the water cup outlet 4110. When drying the water cup device 1000 is required, controlling the valve core 4200 opens the water cup outlet 4110. At this time, the water cup outlet 4110 is connected to the diversion chamber 4130, and the airflow pumped by the air blowing device 3000 enters the diversion chamber 4130 and exits from the water cup outlet 4110, then is pumped to the water receiving chamber 1100. When drying the water cup device 1000 is not required or when drying of the water cup device 1000 is complete, controlling the valve core 4200 closes the water cup outlet 4110, disconnecting the water cup outlet 4110 from the diversion chamber 4130.

[0063] The specific structural cooperation between the housing 4100 and the valve core 4200 can be referred to the water diversion valve in the related technology. In the dishwasher in the related technology, the water diversion valve can control the water flow to different spray arms 2100 in the same direction. Similarly, the diversion device 4000 in this embodiment can control the airflow to different positions through the cooperation between the housing 4100 and the valve core 4200.

[0064] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the spray device 2000 includes a spray arm 2100, and when the flow divider 4000 controls the air blowing device 3000 to connect with the spray device 2000, the air blowing device 3000 is adapted to pump airflow to the spray arm 2100.

[0065] The spray arm 2100 has spray holes. When the dishwasher is in the washing cycle, the circulation pump 5000 pumps water to the spray arm 2100 and sprays it out from the spray holes. Since the spray holes of the spray arm 2100 are small, residual water is likely to remain inside the spray device 2000 after the washing cycle is over. Therefore, in this embodiment, when the diversion device 4000 controls the air blowing device 3000 to connect with the spray device 2000, the airflow pumped by the air blowing device 3000 to the spray device 2000 is specifically directed to the spray arm 2100 and finally sprayed out from the spray holes of the spray arm 2100. The airflow pumped by the air blowing device 3000 carries away the moisture in the spray device 2000, thereby drying the spray device 2000 and preventing the growth of bacteria. The airflow sprayed from the spray holes of the spray arm 2100 can also be blown onto the tableware to dry it.

[0066] Optionally, the spray arm 2100 is configured to be rotatable, and the spray device 2000 rotates synchronously when water is sprayed through the spray arm 2100. Therefore, the spray arm 2100 can also rotate synchronously when air is sprayed, which enhances the drying of tableware.

[0067] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the diversion device 4000 includes a spray arm outlet 4120. When the diversion device 4000 controls the air blowing device 3000 to connect with the spraying device 2000, the airflow pumped by the air blowing device 3000 is suitable to be delivered to the spray arm 2100 through the spray arm outlet 4120, thereby removing the moisture from the spraying device 2000 and achieving the drying of the spraying device 2000.

[0068] For example, the diversion device 4000 can control the opening and closing of the spray arm outlet 4120. When the diversion device 4000 controls the spray arm outlet 4120 to open, the air blowing device 3000 and the spraying device 2000 can be connected. The airflow pumped by the air blowing device 3000 enters the diversion device 4000 and flows out from the spray arm outlet 4120 to be delivered to the spray arm 2100. When the diversion device 4000 controls the spray arm outlet 4120 to close, the air blowing device 3000 and the spraying device 2000 can be disconnected.

[0069] Combination Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, there are multiple spray arm outlets 4120 and multiple spray arms 2100, with at least one spray arm outlet 4120 and at least one spray arm 2100 connected. When the flow divider 4000 controls the air blowing device 3000 to connect with the spraying device 2000, the airflow pumped by the air blowing device 3000 is suitable to enter the spray arm 2100 through at least one of the multiple spray arm outlets 4120.

[0070] Specifically, "multiple" means two or more, such as two, three, four, five or more. In this embodiment, the connection between at least one spray arm outlet 4120 and at least one spray arm 2100 includes, but is not limited to, the following situations: one spray arm outlet 4120 is connected to one spray arm 2100, or one spray arm outlet 4120 is connected to two spray arms 2100, or one spray arm outlet 4120 is connected to three spray arms 2100, and so on. It can also be that two spray arm outlets 4120 are connected to one spray arm 2100, or three spray arm outlets 4120 are connected to one spray arm 2100, and so on.

[0071] As shown in the attached diagram, there are three spray arm outlets 4120 and three spray arms 2100. Each spray arm outlet 4120 is connected to a corresponding spray arm 2100. Spray arm outlets 4120 correspond to the first spray arm outlet 4121, the second spray arm outlet 4122, and the third spray arm outlet 4123. Spray arms 2100 correspond to the first spray arm 2110, the second spray arm 2120, and the third spray arm 2130. The first spray arm outlet 4121 is connected to the first spray arm 2110, the second spray arm outlet 4122 is connected to the second spray arm 2120, and the third spray arm outlet 4123 is connected to the third spray arm 2130. When the flow divider 4000 controls the air blowing device 3000 to connect with the spraying device 2000, the flow divider 4000... The system can control the opening of at least one of the first spray arm outlet 4121, the second spray arm outlet 4122, and the third spray arm outlet 4123. When the diversion device 4000 controls the first spray arm outlet 4121 to open, the airflow can be pumped to the first spray arm 2110 through the first spray arm outlet 4121. When the diversion device 4000 controls the second spray arm outlet 4122 to open, the airflow can be pumped to the second spray arm 2120 through the second spray arm outlet 4122. When the diversion device 4000 controls the third spray arm outlet 4123 to open, the airflow can be pumped to the third spray arm 2130 through the third spray arm outlet 4123. The corresponding spray arm outlet 4120 can be opened and closed according to actual needs, so that the spray device 2000 can be dried more effectively.

[0072] Combination Figure 2 and Figure 5 As shown, in some embodiments, the diversion device 4000 includes a housing 4100 and a valve core 4200. The housing 4100 is provided with a diversion chamber 4130. The valve core 4200 is movably disposed in the diversion chamber 4130 so as to open and close the spray arm outlet 4120. The air blowing device 3000 is connected to the diversion chamber 4130, and the spray arm 2100 is connected to the spray arm outlet 4120. When the valve core 4200 opens the spray arm outlet 4120, the diversion chamber 4130 is connected to the spray arm outlet 4120.

[0073] The valve core 4200 can move in various ways, including but not limited to rotation, reciprocating movement, extension, and deformation. The movement of the valve core 4200 can be driven by a motor. Controlling the movement of the valve core 4200 under appropriate conditions allows for the opening and closing of the spray arm outlet 4120. When drying the spray device 2000 is required, controlling the valve core 4200 opens the spray arm outlet 4120. At this time, the spray arm outlet 4120 connects to the diversion chamber 4130, and the airflow pumped by the air blowing device 3000 enters the diversion chamber 4130 and exits from the spray arm outlet 4120, then is pumped to the spray arm 2100. When drying the spray device 2000 is not required or when drying of the spray device 2000 is complete, controlling the valve core 4200 closes the spray arm outlet 4120, disconnecting the spray arm outlet 4120 from the diversion chamber 4130. When there are multiple spray arm outlets 4120, the corresponding spray arm outlets 4120 are opened and closed as needed.

[0074] The specific structural cooperation between the housing 4100 and the valve core 4200 can be referred to the water diversion valve in the related technology. In the dishwasher in the related technology, the water diversion valve can control the water flow to different spray arms 2100 in the same direction. Similarly, the diversion device 4000 in this embodiment can control the airflow to different positions through the cooperation between the housing 4100 and the valve core 4200.

[0075] The following explanation uses the diversion device 4000, which includes a water cup outlet 4110, a first spray arm outlet 4121, a second spray arm outlet 4122, and a third spray arm outlet 4123, as an example:

[0076] The diversion device 4000 includes a housing 4100 and a valve core 4200. The housing 4100 is provided with a diversion chamber 4130 and a water cup outlet 4110 and a spray arm outlet 4120 adapted to communicate with the diversion chamber 4130. The spray arm outlet 4120 includes a first spray arm outlet 4121, a second spray arm outlet 4122 and a third spray arm outlet 4123. The valve core 4200 is movably disposed in the diversion chamber 4130 to open at least one of the water cup outlet 4110, the first spray arm outlet 4121, the second spray arm outlet 4122 and the third spray arm outlet 4123, and to close the remaining portions of the water cup outlet 4110, the first spray arm outlet 4121, the second spray arm outlet 4122 and the third spray arm outlet 4123.

[0077] The water cup outlet 4110 is connected to the water receiving chamber 1100 of the water cup device 1000, the first spray arm outlet 4121 is connected to the first spray arm 2110 of the spray device 4121, the second spray arm outlet 4122 is connected to the second spray arm 2120 of the spray device 4121, the third spray arm outlet 4123 is connected to the third spray arm 2130 of the spray device 4121, and the diversion chamber 4130 is connected to the air blowing device 3000.

[0078] When the water cup outlet 4110 is opened, the airflow pumped by the air blowing device 3000 is pumped toward the water receiving chamber 1100; when the first spray arm outlet 4121 is opened, the airflow pumped by the air blowing device 3000 is pumped toward the first spray arm 2110; when the second spray arm outlet 4122 is opened, the airflow pumped by the air blowing device 3000 is pumped toward the second spray arm 2120; when the third spray arm outlet 4123 is opened, the airflow pumped by the air blowing device 3000 is pumped toward the third spray arm 2130.

[0079] Combination Figure 4 and Figure 5 As shown, in some embodiments, the diversion device 4000 includes a housing 4100 and a valve core 4200. The housing 4100 is provided with a diversion chamber 4130. The housing 4100 is integrated onto the water cup device 1000, and a water cup outlet 4110 is provided on the housing 4100 to connect the diversion chamber 4130 and the water receiving chamber 1100. For example, the housing 4100 and the water cup device 1000 are integrally formed, or the housing 4100 and the water cup device 1000 are injection molded, reducing the number of parts and reducing leakage points.

[0080] In some embodiments, the air blowing device 3000 is adapted to communicate with the outside environment to draw in outside air. After the dishwasher finishes its washing cycle, the air inside the inner drum (washing chamber) is hot and humid. The air blowing device 3000 draws in outside air, which has a relatively lower temperature and humidity, making it more conducive to drying. In particular, the airflow drawn and pumped by the air blowing device 3000 can be heated to create a hot air drying effect, further improving the drying effect.

[0081] For example, the air blowing device 3000 is connected to the outside environment. Pumped air enters the washing chamber through the spray arm 2100, then through the water cup device 1000 and / or the spray device 2000, and finally exits through the exhaust port of the inner tank. This allows for the drying of the spray device 2000, the water cup device 1000, the inner tank, and the tableware. Optionally, the air blowing device 3000 can heat the pumped airflow to create a hot air drying effect.

[0082] In other embodiments, the air blowing device 3000 can also be connected to the inner liner to draw air from the inner liner to form an internal circulation drying. However, since the air inside the inner liner is hot and humid, the airflow drawn out by the air blowing device 3000 needs to be dehumidified for internal circulation drying.

[0083] Optionally, the air blowing device 3000 includes a fan and an air inlet pipe 3100. One end of the air inlet pipe 3100 is connected to the fan, and the other end blows air towards the flow distribution device 4000. The fan is an axial flow fan. In particular, it also includes a heating component, which is configured to heat the airflow blown by the air blowing device 3000 towards the spray device 2000 and / or the water cup device 1000, thereby creating a hot air drying effect and improving drying efficiency.

[0084] Combination Figures 1 to 9 As shown, in some embodiments, the dishwasher also includes a circulation pump 5000, the inlet of which is connected to the water cup device 1000, the outlet of which is connected to the diverter device 4000, and a conduit of the blowing device 3000 communicating between the water cup device 1000 and the inlet of the circulation pump 5000. With such an arrangement, washing and drying share a common part of the structure. The circulation pump 5000 is adapted to pump water flow to the diverter device 4000, which is adapted to control the water flow to spray from its water cup outlet 4100 and / or from its spray arm outlet 4120.

[0085] When the dishwasher is in a washing cycle, the circulation pump 5000 draws water from the water cup device 1000 and pumps it to the diversion device 4000. The diversion device 4000 opens at least one of the first spray arm outlet 4121, the second spray arm outlet 4122, and the third spray arm outlet 4123, so that water is finally sprayed out from the corresponding first spray arm 2110, second spray arm 2120, or third spray arm 2130 to clean the dishes. When the dishwasher needs to rinse the filter device of the water receiving chamber 1100 of the water cup device 1000, the circulation pump 5000 draws water from the water cup device 1000 and pumps it to the diversion device 4000. The diversion device 4000 opens the water cup outlet 4110, and water is sprayed out from the water cup outlet 4110 to rinse the filter device. When the dishwasher needs drying, the airflow pumped by the air blowing device 3000 is pumped to the diversion device 4000 by the circulation pump 5000. The diversion device 4000 opens at least one of the water cup outlet 4110, the first spray arm outlet, the second spray arm outlet, and the third spray arm outlet, so that the airflow blows towards the water receiving chamber 1100, the first spray arm 2110, the second spray arm 2120, or the third spray arm 2130 to achieve drying of the corresponding parts.

[0086] Combination Figures 1 to 9As shown, in some embodiments, the dishwasher further includes an air distribution valve 7000, which has an air inlet 7400, a first outlet 7100, a second outlet 7200, and a third outlet 7300; the water cup device 1000 has a water receiving chamber 1100 and a drain channel, the first outlet 7100 is connected to the drain channel, the second outlet 7200 is connected to the water receiving chamber 1100, the third outlet 7300 is connected to the inlet of the circulation pump 5000, and the air inlet 7400 is connected to the air blowing device 3000. When the air inlet 7400 is opened, the air distribution valve 7000 can open at least one of the first outlet 7100, the second outlet 7200, and the third outlet 7300; when the air inlet 7400 is closed, the air distribution valve 7000 can open at least two of the first outlet 7100, the second outlet 7200, and the third outlet 7300. When the dishwasher drains water, the water flows away from the water receiving chamber 1100 through the drain channel.

[0087] For example, when the dishwasher is in the washing cycle, the air distribution valve 7000 closes the air inlet 7400 and opens the second outlet 7200 and the third outlet 7300. The circulation pump 5000 draws water from the water cup device 1000. The water in the water cup flows out from the water receiving chamber 1100 and enters the air distribution valve 7000 through the second outlet 7200. Then it flows out through the third outlet 7300 to enter the circulation pump 5000 and is then pumped to the spray device 2000.

[0088] When the dishwasher is drying, the air distribution valve opens the air inlet 7400 and at least one of the first outlet 7100, the second outlet 7200, and the third outlet 7300. The airflow enters the air distribution valve 7000 through the air inlet 7400 and then exits through at least one of the first outlet 7100, the second outlet 7200, and the third outlet 7300, thereby achieving the drying of the drain channel, the water receiving chamber 1100, or the spray arm.

[0089] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
