[0039] Those skilled in the art will appreciate that, unless otherwise stated, the singular forms "a", "an", "said" and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present application refers to the presence of the features, elements and / or components, but does not exclude the presence or addition of one or more other features, elements, components and / or groups thereof. The term "and / or" used herein includes all or any unit and all combinations of one or more associated listed items.

[0040] like Figure 1-5 As shown, the embodiment of the present application provides a dishwasher air duct, which mainly includes a housing 1, a plurality of fixed baffles 2, a rotating baffle 3, a drainage structure 4 and a photo plasma device 5. The housing 1 has a channel 100 for air circulation inside, and the channel 100 is curved and extended; a plurality of fixed baffles 2 are arranged in the channel 100 at intervals along the flow path of the channel 100; the rotating baffle 3 is arranged in the channel 100 and close to the air outlet end of the channel 100; in the windless stage, the rotating baffle 3 is located in a static shielding position; in the windy stage, the rotating baffle 3 rotates from the static shielding position to the ventilation avoidance position relative to the housing 1; the drainage structure 4 is connected to the lower part of the channel 100 for discharging condensed water; the fixed baffle 2 close to the drainage structure 4 can also be used as a water retaining structure; the photo plasma device 5 is detachably connected to the housing 1 and is arranged at the air outlet end of the channel 100.

[0041] In this embodiment, the housing 1 is vertically arranged. The housing wall of the housing 1 is surrounded to form a curved channel 100, which is connected to the cavity 9 of the dishwasher and the fan for ventilating the cavity 9 of the dishwasher during the drying stage.

[0042] The fixed baffles 2 are integrally formed with the housing 1. A plurality of fixed baffles 2 can increase wind resistance, thereby controlling the air volume of the air duct of the dishwasher; the rotating baffle 3 controls the conduction or disconnection of the channel 100 by changing, for example, when there is wind, the rotating baffle 3 is located in the ventilation avoidance position, and the wind flows to the outlet end of the channel 100; when there is no wind, the rotating baffle 3 is located in the static shielding position, and the water vapor in the cavity 9 can enter the channel 100 through the outlet end of the channel 100, and is blocked by the rotating baffle 3 to prevent the water vapor from penetrating into the channel 100.

[0043] The wind in the channel 100 will carry water vapor, and condensed water will be formed in the process of flowing through the channel 100. The condensed water flows to a lower place under the action of gravity and is discharged from the channel 100 from the drainage structure 4 to prevent the condensed water from accumulating and breeding bacteria, thereby polluting the environment of the channel 100. Optionally, the drainage structure 4 is formed integrally with the housing 1. A fixed baffle 2 may be provided around the input end of the drainage structure 4 to prevent the condensed water from continuing to flow without being discharged from the drainage structure 4.

The photo plasma device 5 generates photo plasma through the action of light energy. The wind output through the channel 100 causes the photo plasma separated in the air to flow to every corner of the cavity 9, truly achieving no dead angle coverage, disinfecting bacteria in the cavity 9, and removing the odor in the cavity 9, thereby greatly improving the user experience. In addition, the wind resistance is increased by the fixed baffle 2 to meet the requirements of air volume control, and the air volume of the hot air duct is not affected within a certain range, thereby not affecting the drying performance of the dishwasher. At the same time, the fixed baffle 2 can also minimize the entry of water vapor into the channel 100. Even if it enters the channel 100, condensed water will be formed under the action of the fixed baffle 2, and the condensed water will be discharged through the drainage structure 4.
