The dish washing machine 10 in the utility model can include but is not limited to one or more of the above working modes. Of course, the above description is only some embodiments of the utility model, and is not a limitation on the protection scope of the utility model.

[0043] As described above, when it is necessary to perform overall residual water removal and drying operations on the dish washing machine 10, air needs to be sent to different positions, therefore, the air distribution valve 15 is further arranged in the utility model to adjust the blowing direction of the airflow delivered by the air inlet device 16.

[0044] As Figures 1 to 7In some embodiments, the dishwasher 10 further comprises a distribution valve 15 connected to the air inlet device 16, the washing pump 12 and the water cup 11 respectively, and the distribution valve 15 is configured to switchingly connect any two of the air inlet device 16, the washing pump 12 and the water cup 11. For example, the distribution valve 15 connects the air inlet device 16 and the washing pump 12; or, the distribution valve 15 connects the air inlet device 16 and the water cup 11; or, the distribution valve 15 connects the washing pump 12 and the water cup 11, etc.

[0045] The distribution valve 15 of the utility model can have an air inlet 1505, a first outlet 1501 and a second outlet 1502, the first outlet 1501 is connected to the water cup 11, and the second outlet 1502 is connected to the inlet of the washing pump 12. The distribution valve 15 can include but is not limited to one or more of the following states.

[0046] The first communication state is that the air inlet 1505 is connected to the first outlet 1501 and disconnected from the second outlet 1502, the air inlet device 16 is connected to the water cup 11 and disconnected from the washing pump 12, and the air flow of the air inlet device 16 can be controlled to be sent to the water cup 11 to dry the water cup 11.

[0047] The second communication state is that the air inlet 1505 is connected to the second outlet 1502 and disconnected from the first outlet 1501, and the air inlet device 16 is connected to the washing pump 12 and disconnected from the water cup 11. The air flow of the air inlet device 16 can be controlled to be sent to the washing pump 12 to dry the washing pump 12, and the heating unit of the washing pump 12 can also be used to heat the air flow to improve the drying effect of the dishwasher 10.

[0048] The first cut-off state is that the air inlet 1505 is disconnected from the first outlet 1501 and the second outlet 1502, and the first outlet 1501 and the second outlet 1502 are connected, and the washing pump 12 is connected to the water cup 11. At this time, the air inlet device 16 will not send air to the washing pump 12 and the water cup 11, and the water cup 11 is connected to the inlet of the washing pump 12, so that the water in the water cup 11 can be sent to the washing pump 12 through the air inlet device 16, thereby realizing the cleaning of the dishes in the dishwasher 10.

[0049] Through the above-mentioned embodiments, the air flow direction of the air inlet device 16 can be controlled by the distribution valve 15, thereby realizing the drying of different positions in the dishwasher 10, and achieving the purpose of optimizing the drying effect in the dishwasher 10.

[0050] Optionally, the air distribution valve 15 comprises a housing 151, the air inlet 1505, the first outlet 1501 and the second outlet 1502 are arranged on the housing 151, and the first outlet 1501 and the second outlet 1502 are distributed along the circumference of the housing 151; an air distribution member 152 is rotatably arranged on the housing 151 along the circumference of the housing 151, and the air distribution member 152 is configured to open and close the first outlet 1501 and the second outlet 1502 by rotation. Thus, the user can switch the first communication state, the second communication state and the first cut-off state by rotating the air distribution member 152, which can simplify the structure and control of the air distribution valve 15 and facilitate quick adjustment of the drying state of the dishwasher 10.

[0051] As Figures 3 to 7 In some other embodiments, the dishwasher 10 further comprises a drainage device 17 connected to the air distribution valve 15. The drainage device 17 communicates with the water cup 11, and the water in the water cup 11 can be drained under the action of the drainage device 17, thereby realizing the drainage of the water in the water cup 11. The drainage device 17 can be in the form of suction drainage, specifically, the drainage device 17 can be used to suck water from the drainage port and then discharge the sucked water out of the water cup 11.

[0052] Optionally, the air distribution valve 15 has the air inlet 1505, the first outlet 1501, the second outlet 1502 and the third outlet 1503, the first outlet 1501 communicates with the water cup 11, the second outlet 1502 communicates with the inlet of the washing pump 12, and the third outlet 1503 communicates with the drainage device 17. The air distribution valve 15 can switch the flow direction of the air flow, and can communicate the air inlet 1505 with at least one of the first outlet 1501, the second outlet 1502 and the third outlet 1503 through the air distribution valve 15, or can isolate the air inlet 1505 from the first outlet 1501, the second outlet 1502 and the third outlet 1503 through the air distribution valve 15. In this way, multiple outlets are provided, which can facilitate the control of the flow direction of the air flow, so as to facilitate the air blowing and drying of different areas of the dishwasher 10, thereby improving the overall drying effect of the dishwasher 10. The air distribution valve 15 has multiple communication states, and in the communication state, the air distribution valve 15 controls at least one of the first outlet 1501, the second outlet 1502 and the third outlet 1503 to be opened and communicate with the air inlet 1505. The flow direction of the air flow can be controlled to optimize the air blowing and drying effect of the dishwasher 10 and improve the drying efficiency and effect of the dishwasher 10.

[0053] As Figure 4, the air inlet 1505 is communicated with the third outlet 1503, and is disconnected with the first outlet 1501 and the second outlet 1502. Wherein, in the fourth communication state, the third outlet 1503 is opened, and the air flow can be sent to the drainage assembly after passing through the air distribution valve 15, so as to dry the drainage assembly. Since a large amount of water can be stored in the drainage assembly, the air pressure of the air flow sent to the drainage assembly can be improved by separately sending air to the drainage assembly, so as to improve the drainage effect of the drainage assembly.

[0054] As Figure 5 , the plurality of communication states further include a fifth communication state, in which the air inlet 1505 is communicated with the first outlet 1501 and the second outlet 1502, and is disconnected with the third outlet 1503. Wherein, in the fifth communication state, the third outlet 1503 and the first outlet 1501 are opened, and the air flow can be sent to the drainage assembly and the water cup 11 after passing through the air distribution valve 15, so as to dry the drainage assembly and the water cup 11. In the process of drying the water cup 11 by blowing air, a part of the air flow is sent to the drainage assembly. In the process of drying the water cup 11, the high-humidity air flow in the water cup 11 can be sent to the drainage assembly, and the air flow entering the drainage assembly can be used to blow away the moisture entering the drainage assembly, so as to effectively improve the air blowing drying effect of the water cup 11 and the drainage assembly.

[0055] As Figure 6 , the plurality of communication states further include a sixth communication state, in which the air inlet 1505 is communicated with the second outlet 1502, and is disconnected with the first outlet 1501 and the third outlet 1503. Wherein, in the sixth communication state, the second outlet 1502 is opened, and the air flow can be sent to the washing pump 12 after passing through the air distribution valve 15, so as to dry the washing pump 12. Therefore, the drying effect of the washing pump 12 can be improved by separately sending air to the washing pump 12.

[0056] In addition, as Figure 7In the second cut-off state, the first outlet 1501 and the second outlet 1502 are connected, the air inlet 1505 is closed, and the fluid in the air distributor 16 is difficult to flow into the air distributor 15, but the fluid in the air distributor 15 can flow into the washing pump 12 through the first outlet 1501 and the second outlet 1502. Thus, when the dishwasher 10 is cleaning dishes, the washing pump 12 can use the water in the water cup 11 to clean the dishes, thereby simplifying the control of the air distributor 15, and facilitating the stable and convenient operation of the dishwasher 10.

[0057] In some embodiments, the air distributor 15 comprises a housing 151 and an air distributing member 152. The housing 151 is provided with an air inlet 1505 and a plurality of outlets distributed along the circumference of the housing 151. The air distributing member 152 is rotatably arranged in the housing 151 along the circumference of the housing 151 and is configured to open and close the plurality of outlets and the air inlet 1505 by rotation. The structure of the air distributor 15 can be simplified, and the stability and safety of the operation of the air distributor 15 can be improved, and the flow direction of the air flow can be switched in time and quickly.

[0058] Optionally, the housing 151 is further provided with a closed portion 1504. The third outlet 1503, the first outlet 1501, the second outlet 1502, and the closed portion 1504 are distributed along the circumference of the housing 151. Thus, the flow direction of the air flow can be controlled by the air distributing member 152, the structure of the heat exchange device can be simplified, and the stability of the operation of the heat exchange device can be improved. In some examples, the third outlet 1503, the first outlet 1501, the second outlet 1502, and the closed portion 1504 are sequentially distributed along the circumference of the housing 151. The air distributing member 152 can be configured to simultaneously block two adjacent outlets.

[0059] In combination with the foregoing embodiments, the fourth communication state, the fifth communication state, the sixth communication state, and the cutoff state can be quickly achieved. In the fourth communication state, the air distribution member 152 can shield the fourth outlet and the fifth outlet, and at this time the sixth outlet is opened; in the fifth state, the air distribution member 152 rotates to shield the fifth outlet and the closed portion 1504, and at this time the sixth outlet and the fourth outlet are opened; in the sixth communication state, the air distribution member 152 shields the sixth outlet and the fourth outlet, and the fifth outlet is opened; and in the cutoff state, the air distribution member 152 shields the sixth outlet and the closed portion 1504, and the fourth outlet and the fifth outlet are opened. Of course, the air distribution member 152 in the utility model can also be provided in other forms, and is beneficial to being provided in correspondence with the air outlet device having the first outlet 1501 and the second outlet 1502.

[0060] It can be seen that the air distribution member 152 shields adjacent portions each time, so that the air distribution member 152 can be provided in a continuous plate structure, and of course, the air distribution member 152 can also be provided in a discontinuous multiple plate structure.

[0061] Optionally, the third outlet 1503, the first outlet 1501, the second outlet 1502, and the closed portion 1504 are distributed at equal intervals along the circumference of the housing 151.

[0062] As Figures 1 to 7 In some embodiments, the air distribution member 152 includes a baffle 1521 that is movable along the circumference of the housing 151 and is used to close and open the third outlet 1503, the first outlet 1501, and the second outlet 1502. The movement of the baffle 1521 can be used to switch the air distribution valve 15 between different communication states, simplify the structure of the air distribution valve 15, and achieve rapid switching of the air distribution valve 15 between different communication states.

[0063] The baffle 1521 is provided in a sheet shape that continuously extends along the circumference of the housing 151, so that the structural strength of the baffle 1521 can be improved, and the baffle 1521 can be conveniently used to switch the state of the air distribution valve 15. Of course, the baffle 1521 in the utility model can also be provided in a plurality of discontinuous sheets, for example, in some examples, the baffle 1521 is provided with a first sheet portion and a second sheet portion that are distributed along the circumference of the housing 151.

[0064] The air distribution valve 15 is connected between the inlet of the washing pump 12 and the outlet of the water cup 11. In combination with the foregoing examples, the first outlet 1501 communicates with the water cup 11, and the second outlet 1502 communicates with the washing pump 12. In this way, the requirement that the water cup 11 and the washing pump 12 are connected during a conventional washing process can be fully met, and the requirement that air blowing by the air inlet device 16 is used for drying can also be met, the structure of the dishwasher 10 is simplified, and the product performance of the dishwasher 10 is optimized.

[0065] In addition, in some embodiments, the dishwasher 10 further comprises a water distribution valve 14, which can be used to connect a spraying device, wherein the spraying device can have a plurality of spraying arms, and the water distribution valve 14 can be used to switch the water path and the gas path to select the flow direction of the water path or the gas path. Optionally, the spraying assembly can comprise a top spraying arm, a middle spraying arm 132, and a lower spraying arm 133. The top spraying arm, the middle spraying arm 132, and the lower spraying arm 133 are provided with driving holes, which can drive the spraying arms to rotate under the action of the gas flow. At the same time, the gas is sprayed out of the spraying holes on the spraying arms and directly sprayed on the tableware to blow away the water droplets on the tableware. At this time, the rotating spraying arms can uniformly spray the gas in all directions on the tableware. After a certain time, the gas can dry the tableware and blow away the residual water in the pipeline. This greatly shortens the drying time and improves the drying effect.

[0066] In the process of the gas flow or the water flow, the water flow or the gas flow can pass through the washing pump 12 and the water distribution valve 14 and then enter the spraying assembly. At this time, the water flow or the gas flow can be heated by the heating unit. Heating the water flow can improve the efficiency and effect of cleaning the tableware. Heating the gas flow can facilitate drying the inner cavity of the spraying assembly, the washing cavity, and the tableware, thereby improving the drying efficiency and effect of the dishwasher 10.

[0067] Optionally, the water distribution valve 14 can have a first communication port and a second communication port, wherein the first communication port is in communication with the water cup 11, and the second communication port is in communication with the spraying device. The water distribution valve 14 has a first working state and a second working state. In the first working state, the first communication hole 141 is in communication with the outlet of the washing pump 12. In the second working state, the second communication hole 142 is in communication with the outlet of the washing pump 12. Since the water distribution valve 14 is connected with the outlet of the washing pump 12, the water and the gas flow delivered from the washing pump 12 will enter the water distribution valve 14. At this time, the water distribution valve 14 can distribute the fluid to control the fluid to enter the water cup 11 or the spraying assembly. The fluid passing through the washing pump 12 can be heated by the heating unit. The utility model mainly takes the air inlet device 16 as an example to supply air to the washing pump 12. The gas flow will be heated during the process of passing through the washing pump 12. The heated gas flow is sent to the water distribution valve 14, which can have a distribution effect. The water distribution valve 14 can deliver the gas flow heated by the heating unit to the water cup 11 to dry the internal space of the water cup 11 by hot air and remove residual water. Alternatively, the water distribution valve 14 can also send the gas flow heated by the heating unit to the spraying device to remove residual water and dry the pipeline leading to the spraying device, the inner cavity of the spraying device, the spraying port of the spraying device, the tableware in the washing cavity of the dishwasher 10, and the interior of the washing cavity of the dishwasher 10. In addition, the water distribution valve 14 can be configured to send the gas flow heated by the heating unit to the spraying device and the water cup 11 at the same time, thereby improving the drying efficiency and effect of the dishwasher 10.

[0068] The heating unit in the utility model is integrated in the washing pump 12, and in the dish washing machine 10 of the prior art, the heating unit is used for heating water passing through the washing pump 12, so as to improve cleaning efficiency and effect, and in the utility model, the heating unit is also used for heating air, therefore, the running state of the heating unit needs to be understood, so as to heat the air flow by the washing pump 12, and meanwhile, the safety hidden danger caused by dry burning is avoided, therefore, in some embodiments of the utility model, the washing pump 12 further comprises a temperature measuring unit, and the temperature measuring unit is used for detecting the temperature of fluid in the pump cavity of the washing pump 12, so that the heating condition of the air flow by the washing pump 12 can be understood in time, so as to control the temperature of the air flow and optimize the drying effect. In addition, the temperature measuring unit can also be arranged to detect the temperature of the pump cavity wall, so that the problem of excessively high temperature of the pump cavity wall in the process of heating the air flow is avoided, and the stability and safety in the operation process of the dish washing machine 10 are further improved.

[0069] In some embodiments, the air inlet device 16 comprises a fan 161 and an air inlet pipe 162, one end of the air inlet pipe 162 is connected to the fan 161, and the other end is used for blowing air, wherein the fan 161 is an axial flow fan 161.
