DETAILED DESCRIPTION

[0022] Embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0023] After the completion of the washing program, the dishwasher usually discharges the washing water through the drainage device, and the residues, oil stains, detergents and the like on the tableware will be discharged along with the water flow through the drainage passage. If the water in the drainage passage cannot be completely discharged, the inside will be in a humid state for a long time, which is easy to breed bacteria. Based on this, the utility model provides a water cup assembly 100 which can be used for a dishwasher, can remove the residual water in the drainage pipeline, and can dry the drainage pipeline.

[0024] In combination Figure 1 , the water cup assembly 100 comprises a water cup 10, and the water cup 10 has a water storage cavity 11 and a drainage port. The drainage port is communicated with the water storage cavity 11. Specifically, the water storage cavity 11 is used for receiving and storing water. For example, at the beginning of the washing program, the washing water will be introduced into the water storage cavity 11, so that the washing pump of the dishwasher can draw water from the water storage cavity 11 for washing tableware in the dishwasher; during the washing process, the washing water falls into the water storage cavity 11 after washing the tableware in the washing cavity; after the completion of the washing and when the drainage is needed during the washing process, the water in the water storage cavity 11 can be discharged through the drainage port.

[0025] In combination Figure 1 , the water cup assembly 100 further comprises a drainage device 20, and the drainage device 20 comprises a pump cavity 21 and an impeller 22. The pump cavity 21 has a pump inlet 211 and a pump outlet 212, and the pump inlet 211 of the pump cavity 21 is communicated with the drainage port. The impeller 22 drives the fluid from the pump inlet 211 to the pump outlet 212. Specifically, the water in the water storage cavity 11 can be sent to the drainage device 20 through the drainage port, and the impeller 22 drives the water flow of the pump inlet 211 to the pump outlet 212 to realize the discharge of the water in the water storage cavity 11, that is, the drainage device 20 draws water from the drainage port through the impeller 22, and then discharges the sucked water from the pump outlet 212.

[0026] In combination Figure 1The water cup assembly 100 further comprises an air inlet device 30, a blowing port 31 of the air inlet device 30 is communicated with the drainage device 20, and the air inlet device 30 blows air to the drainage device 20 through the blowing port 31. The air inlet device 30 is connected to the downstream of the pump cavity 21, so that the positive pressure air flow generated by the air inlet device 30 can drive the water in the drainage device 20 to be discharged, the residual water downstream of the pump cavity 21 can be discharged, and the evaporation of the residual water in the drainage device 20 can be accelerated, so that the drainage device 20 can be dried. It can be understood that, after the water in the drainage device 20 is discharged, some residual water will remain in the downstream of the pump cavity 21, which is easy to breed bacteria and produce odor. By connecting the air inlet device 30 to the downstream of the pump cavity 21, the positive pressure air flow can be provided to the downstream of the pump cavity 21 of the drainage device 20. If there is residual water in the downstream of the pump cavity 21, the residual water can be discharged under the action of the air pressure. When there is residual water on the inner wall surface of the downstream of the pump cavity 21 of the drainage device 20, the evaporation of the residual water on the inner wall surface can be accelerated by the action of the air flow, so that the pump cavity 21 of the drainage device 20 can be dried.

[0027] According to the water cup assembly 100 provided by the embodiment of the present application, the air inlet device 30 can supply air to the drainage device 20, and the air inlet device 30 is connected to the downstream of the pump cavity 21, so that the positive pressure air flow can remove the residual water downstream of the pump cavity 21 and dry the residual water, thereby avoiding the problems that the downstream of the pump cavity 21 of the drainage device 20 is in a humid environment for a long time, bacteria breed, odor is produced, or the washing effect of the dishwasher is affected. In addition, the dishwasher can be used to store tableware, and the problems of bacterial breeding caused by excessive humidity during storage can be reduced.

[0028] The air inlet device 30 blows air to the drainage device 20 through the blowing port 31. For example, the air inlet device 30 can comprise a driving member 32, which can be a gas pump or a fan.

[0029] In addition, the downstream of the pump cavity 21 can be connected to a drain pipe 23, that is, the water in the water storage cavity 11 is driven by the impeller 22 to be discharged to the outside of the dishwasher through the drain pipe 23, and the residual water in the drain pipe 23 can be dried by the air inlet device 30. Alternatively, the dishwasher can be provided with a breather, the breather can be provided with a drain passage, and the downstream of the pump cavity 21 can be connected to the drain passage of the breather, that is, the water in the water storage cavity 11 is driven by the impeller 22 to be discharged to the outside of the dishwasher through the drain passage of the breather, and the residual water in the drain passage of the breather can be dried by the air inlet device 30, so that the residual water in the drain passage of the breather is prevented from breeding bacteria and producing odor.

[0030] If there is residual water in the drain pipe 23 or the drain passage, the residual water can be discharged under the action of the positive pressure airflow; if there is no residual water in the drain pipe 23 or the drain passage, but the inner wall surface of the drain pipe 23 or the drain passage has residual water, the positive pressure airflow can accelerate the evaporation of the residual water on the inner wall surface, so as to realize the drying of the drain device 20.

Specifically, the air inlet device 30 sends air to the drain device 20 through the air blowing port 31. It can be understood that the drain pipe 23 is usually arranged as a flexible pipe. The water flow in the drain pipe 23 may be not smooth due to bending. The decrease of water flow speed in the drainage process can make dirt and bacteria more easily adhere and accumulate in the drain pipe 23. The drain pipe 23 is in a humid environment for a long time, which is easy to breed bacteria and produce odor. The air blowing port 31 is arranged upstream of the drain pipe 23, which is convenient for blowing air into the drain pipe 23 through the air inlet device 30, providing positive pressure to the drain pipe 23, and making the residual water in the drain pipe 23 dry and dry, avoiding the humid environment in the drain pipe 23 which is easy to breed bacteria and produce odor, etc.
