[0080] The diverging valve 20 also has a second communication state, in which the air inlet device 30 is communicated with the water cup 11 and the drain device 12, and the air inlet device 30 is disconnected with the washing pump 131.

[0081] The diverging valve 20 also has a third communication state, in which the air inlet device 30 is communicated with the washing pump 131, and the air inlet device 30 is disconnected with the water cup 11 and the drain device 12.

[0082] The diverging valve 20 also has a cutoff state, in which the air inlet device 30 is disconnected with the drain device 12, the water cup 11 and the washing assembly 13, and the water cup 11 and the washing pump 131 are communicated.

[0083] In the first communication state, the air flow delivered by the air inlet device 30 can be sent to the drain device 12, the residual water in the drain device 12 is driven out by the positive pressure air flow, and the drain device 12 is dried by the air flow; in the second communication state, the air flow delivered by the air inlet device 30 can be sent to the drain device 12 and the water cup 11, so as to utilize the drain device 12.

[0084] As Figure 14 and Figure 7 In some embodiments, the air outlet includes a first outlet 201, a second outlet 202 and a third outlet 203, the first outlet 201 is communicated with the drain assembly 12, the second outlet 202 is communicated with the water cup 11, and the third outlet 203 is communicated with the washing assembly 13. The diverging valve 20 can switch the flow direction of the air flow, and the air inlet 208 can be communicated with at least one of the first outlet 201, the second outlet 202 and the third outlet 203 through the diverging valve 20, or the air inlet 208 can be isolated from the first outlet 201, the second outlet 202 and the third outlet 203 through the diverging valve 20. In this way, multiple outlets are provided, which can facilitate the control of the flow direction of the air flow, so as to blow and dry different areas of the dishwasher 100, thereby improving the overall drying effect of the dishwasher 100.

[0085] As Figure 14 and Figure 7 In some embodiments, the diverging valve 20 has multiple communication states, in which the diverging valve 20 controls at least one of the first outlet 201, the second outlet 202 and the third outlet 203 to be opened and communicated with the air inlet 208. The flow direction of the air flow can be controlled, so as to optimize the air blowing and drying effect of the dishwasher 100 and improve the drying efficiency and effect of the dishwasher 100.

[0086] The shunt valve 20 in the utility model can have multiple communication states, for example, can include controlling the air inlet 208 to communicate with the first outlet 201; controlling the air inlet 208 to communicate with the second outlet 202; controlling the air inlet 208 to communicate with the third outlet 203; controlling the air inlet 208 to communicate with the first outlet 201 and the second outlet 202; controlling the air inlet 208 to communicate with the first outlet 201 and the third outlet 203; controlling the air inlet 208 to communicate with the second outlet 202 and the third outlet 203; controlling the air inlet 208 to communicate with the first outlet 201, the second outlet 202 and the third outlet 203 and the like. Of course, the shunt valve 20 in the utility model can not need to have all these states, in order to simplify the control of the shunt valve 20 and simplify the structure of the shunt valve 20, the shunt valve 20 in the utility model can only include part of the above communication states.

[0087] In some embodiments of the utility model, as Figure 10 The multiple communication states include a first communication state, in which the first outlet 201 is opened and the second outlet 202 and the third outlet 203 are closed. In the first communication state, the first outlet 201 is opened, and the airflow can be sent to the drainage assembly 12 after passing through the shunt valve 20, the residual water in the drainage assembly 12 is driven out by using the positive pressure airflow, and the drainage assembly 12 is dried, because a large amount of water can be stored in the drainage assembly 12, the air pressure of the airflow sent to the drainage assembly 12 can be improved by separately feeding air to the drainage assembly 12, thereby improving the drainage effect of the drainage assembly 12.

[0088] As Figure 11 The multiple communication states further include a second communication state, in which the first outlet 201 and the second outlet 202 are opened and the third outlet 203 is closed. In the second communication state, the first outlet 201 and the second outlet 202 are opened, and the airflow can be sent to the drainage assembly 12 and the water cup 11 after passing through the shunt valve 20, so as to dry the drainage assembly 12 and the water cup 11, in the process of blowing and drying the water cup 11, part of the airflow is sent to the drainage assembly 12, in the process of drying the water cup 11, the high humidity airflow in the water cup 11 can be sent to the drainage assembly 12, and the humidity in the drainage assembly 12 is blown away by the airflow entering the drainage assembly 12, thereby effectively improving the blowing and drying effect of the water cup 11 and the drainage assembly 12.

[0089] As Figure 12The plurality of communication states further include a third communication state in which the third outlet 203 is opened and the first outlet 201 and the second outlet 202 are closed. In the third communication state, the third outlet 203 is opened, and the air flow can be sent to the washing assembly 13 after passing through the flow distribution valve 20 to facilitate drying of the washing assembly 13.

At this time, the air inlet 208 is closed, and the air flow delivered by the air inlet device 30 is difficult to enter the flow distribution valve 20, and the fluid flowing in the flow distribution valve 20 is also difficult to enter the air inlet device 30 from the air inlet 208, and when the second outlet 202 and the third outlet 203 are communicated, the fluid in the water cup 11 can be sent to the washing assembly 13 through the flow distribution valve 20, so that when the dishwasher 100 is working to clean tableware, the washing assembly 13 can use the water in the water cup 11 to clean the tableware, thereby simplifying the control of the flow distribution valve 20, so that the dishwasher 100 can operate more stably and conveniently.

In combination with the foregoing embodiments, the flow distribution valve 20 has multiple communication states and cut-off states, and in the cut-off state, the flow distribution valve 20 can connect the water cup 11 and the washing assembly 13, at this time, the water cup 11 and the washing assembly 13 are communicated, by connecting the flow distribution valve 20 between the water cup 11 and the washing assembly 13, the flow distribution valve 20 can be used as a channel between the water cup 11 and the washing assembly 13 to meet the washing requirement, so that the change of the structure of the dishwasher 100 can be reduced to maintain the stability of the dishwasher 100.
