[0044] In addition, by arranging the partition plate 30 to separate the air inlet chamber 111 and the air outlet chamber 112, the air inlet chamber 111 and the air outlet chamber 112 are separated in the cut-off position of the air distribution block 20, so that two chambers are formed in the air distribution valve 100. At this time, the air inlet 12 does not need to pass the airflow into the air outlet chamber 112, so that the air outlet chamber 112 forms an independent chamber. The plurality of outlets are arranged on the wall of the air outlet chamber 112. Exemplarily, at least two of the plurality of outlets can be in communication with the air outlet chamber 112, and the plurality of outlets can be connected with different pipelines.

[0046] For example, the plurality of outlets can include a first outlet 131 and a second outlet 132, and in the cut-off position, the first outlet 131 and the second outlet 132 are communicated with the air outlet cavity 112, that is, the first outlet 131 and the second outlet 132 are communicated, and the fluid in the pipeline connected with the first outlet 131 can enter the pipeline connected with the second outlet 132 through the air distribution valve 100, or the fluid in the pipeline connected with the second outlet 132 can enter the pipeline connected with the first outlet 131 through the air distribution valve 100, and the fluid cannot enter the air inlet 12; for another example, the plurality of outlets can include a first outlet 131, a second outlet 132 and a third outlet 133, and in the cut-off position, the second outlet 132 and the third outlet 133 are communicated with the air outlet cavity 112, and the first outlet 131 is disconnected with the air outlet cavity 112, that is, the second outlet 132 and the third outlet 133 are communicated, and the fluid in the pipeline connected with the second outlet 132 can enter the pipeline connected with the third outlet 133 through the air distribution valve 100, or the fluid in the pipeline connected with the second outlet 132 can enter the pipeline connected with the first outlet 131 through the air distribution valve 100, and the fluid cannot enter the air inlet 12 and the third outlet 133. The partition plate 30 is arranged in the chamber to divide the air inlet cavity 111 and the air outlet cavity 112, and the partition plate 30 is matched with the air distribution block 20, the air distribution block 20 can be switched to the communication position to connect the air inlet cavity 111 and the air outlet cavity 112 when it is required to distribute air flow to the outlet, and the air distribution block 20 can be switched to the cut-off position when it is required to connect the pipelines connected with the outlets, so that the use scene of the air distribution valve 100 is enriched.

Alternatively, the second communication hole 221 can include a plurality of second communication holes corresponding to a plurality of communication positions respectively, and the corresponding second communication hole 221 is communicated with the first communication hole 31 in one communication position.

[0050] In some embodiments of the utility model, the air distribution block 20 controls at least one of the multiple outlets to be in communication with the air outlet chamber 112 in the communication position, specifically, in the communication position, the air inlet chamber 111 is in communication with the air outlet chamber 112, the airflow entering the air inlet 12 can enter the air outlet chamber 112, the air distribution block 20 controls the air outlet chamber 112 to be in communication with at least one of the outlets, so as to distribute the airflow to at least one of the outlets according to actual use requirements.

[0051] Exemplarily, in the communication position, the air distribution block 20 can control the outflow cavity 112 to communicate with one outlet, or control the outflow cavity 112 to simultaneously communicate with two outlets. For example, the plurality of outlets include a first outlet 131, a second outlet 132 and a third outlet 133, in the communication position, the air distribution block 20 can control the outflow cavity 112 to communicate with the first outlet 131, and control the outflow cavity 112 to be disconnected with the second outlet 132 and the third outlet 133, that is, the airflow entering the air inlet 12 can only flow out from the first outlet 131. For another example, in the communication position, the air distribution block 20 can control the outflow cavity 112 to simultaneously communicate with the first outlet 131 and the second outlet 132, and control the outflow cavity 112 to be disconnected with the third outlet 133, that is, the airflow entering the air inlet 12 can simultaneously flow out from the first outlet 131 and the second outlet 132. Of course, the air distribution block 20 can also be provided in other forms in the communication position to control the communication between the plurality of outlets and the outflow cavity 112, and the specific form can be adjusted according to the pipeline connected with the plurality of outlets and the actual use requirement, and those skilled in the art can easily obtain other setting forms according to the above description.

[0052] Exemplarily, the air inlet 12 can be connected with a blowing device 300, the blowing device 300 introduces airflow into the air distribution valve 100 through the air inlet 12, and the airflow direction is controlled by the air distribution block 20, so as to distribute the airflow to different outlets according to the actual use requirement.

[0053] In some embodiments of the utility model, the air distribution block 20 controls at least two of the plurality of outlets to communicate with the outflow cavity 112 in the cut-off position. Specifically, the air distribution block 20 is spaced apart from the outflow cavity 112 in the cut-off position, at this time, the air inlet 12 does not need to introduce airflow into the outflow cavity 112, so that the outflow cavity 112 forms an independent chamber, and the plurality of outlets are arranged on the wall of the outflow cavity 112, at least two of the plurality of outlets communicate with the outflow cavity 112, exemplarily, the at least two outlets can be connected with different pipelines, in the cut-off position, the fluid in different pipelines can flow through the air distribution valve 100, and will not enter the air inlet 12, thereby enriching the use scene of the air distribution valve 100.

[0054] In combination Figure 5 In some embodiments of the utility model, the plurality of outlets include a first outlet 131, a second outlet 132 and a third outlet 133, the air distribution block 20 further includes a baffle 21, the baffle 21 is arranged in the outflow cavity 112, and the baffle 21 is used for shielding and opening the outlet. By shielding and opening the outlet through the baffle 21, the structure of the air distribution valve 100 is simplified, and a complex flow channel structure in the air distribution valve 100 is avoided.

[0055] In addition, the plurality of outlets include a first outlet 131, a second outlet 132, and a third outlet 133, which can be connected to different components, respectively.

[0056] For example, the air distribution valve 100 can be used in a washing appliance such as a dishwasher, a washing machine, or a sink dishwasher, which includes a water cup 210, a washing pump 230, and a drain pump 220, and is connected to the water cup 210, the washing pump 230, and the drain pump 220. Figure 9 For example, the drain pump 220 is connected to the first outlet 131, the water cup 210 is connected to the second outlet 132, and the washing pump 230 is connected to the third outlet 133; or, the water cup 210 is connected to the first outlet 131, the drain pump 220 is connected to the second outlet 132, and the washing pump 230 is connected to the third outlet 133. After the completion of the washing program, the air distribution block 20 can be switched to the communication position, and the flapper 21 is opened and closed to open and close the outlets, so that air is introduced into the water cup 210, the washing pump 230, and the drain pump 220 through the air inlet 12. It can be understood that, after the completion of the washing work of the washing appliance, the water cup 210, the washing pump 230, and the drain pump 220 usually contain residual water. By introducing air into the water cup 210, the washing pump 230, and the drain pump 220 through the air inlet 12, the residual water in the water cup 210, the washing pump 230, and the drain pump 220 can be discharged by using the positive pressure air flow, and the evaporation of the residual water in the water cup 210, the washing pump 230, and the drain pump 220 can be accelerated, so that the water cup 210, the washing pump 230, and the drain pump 220 are dried, bacteria are prevented from breeding due to the residual moisture after a long storage, and an odor is prevented from being generated, so that the washing appliance causes secondary pollution to tableware.

[0057] The baffle 21 is used for shielding and opening the outlet, and the baffle 21 can shield and open different outlets. Specifically, in the communication position, the baffle 21 can open at least one opening, so as to guide the airflow in the air inlet cavity 111 to the at least one opening. For example, in one communication position, the baffle 21 can open the first outlet 131 and shield the second outlet 132 and the third outlet 133; in another communication position, the baffle 21 can open the third outlet 133 and shield the first outlet 131 and the second outlet 132. That is, in the communication position, the position of the baffle 21 can be switched to realize that the air blowing device 300 blows air to the first outlet 131 and the third outlet 133 alone; or in one communication position, the baffle 21 can open the first outlet 131 and shield the second outlet 132 and the third outlet 133; in another communication position, the baffle 21 can open the first outlet 131 and the second outlet 132 and shield the third outlet 133. That is, in the communication position, the air blowing device 300 can blow air to one outlet alone or to two outlets simultaneously. Of course, the baffle 21 of the utility model can also have other forms of shielding and opening the outlet, and the specific form can be adjusted according to actual use requirements. The utility model does not list one by one, and those skilled in the art can easily obtain other setting forms of the baffle 21 shielding and opening different outlets according to the above description.

[0058] In addition, the baffle 21 is used for shielding and opening the outlet, and in the cut-off position, the baffle 21 can be used to open at least two outlets, so as to place the at least two outlets in the communication position through the air outlet cavity 112.

[0059] In some embodiments of the utility model, the baffle 21 is provided in an integral structure, which simplifies the control mode of the air distribution valve 100 and improves the working stability of the air distribution valve 100.

In the communication position, the first shielding portion shields the first outlet 131, the second shielding portion shields the third outlet 133, and the second outlet 132 is communicated with the air outlet cavity 112. At this time, the air blowing device 300 can blow air to the drainage pump 220 to remove residual water in the drainage pump 220, so as to avoid that bacteria breed and odor is generated due to the accumulation of residual water in the drainage pump 220. In the cut-off position, the first shielding portion shields the second outlet 132 and opens the first outlet 131, and the second shielding portion opens the third outlet 133. At this time, the first outlet 131 and the third outlet 133 are both communicated with the air outlet cavity 112, so as to facilitate the water in the water cup 210 to enter the washing pump 230.
