By adopting the above structure, when the exhaust device 2 is shut down, the flap 23 is in the second position under the action of gravity and fits with the inner wall of the steam inlet part 211 to block the air duct 202, and can effectively prevent the water vapor and splashing washing water in the washing cavity 101 from entering the air duct 202 and causing water leakage or damage to the fan assembly 22. When the dishwasher enters the drying and exhaust stage, the fan assembly 22 starts to work, draws air into the air duct 202 to form a negative pressure, and the flap 23 rotates and opens under the action of the negative pressure, and the air duct 202 is communicated with the dishwasher inner liner to start exhausting.

[0060] As Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines that: the air duct 202 further includes an air outlet duct 2023, and the air outlet duct 2023 communicates with the condensation duct 2022 and the air outlet 203. The setting of the air outlet duct 2023 can further increase the effective condensation area of the air duct housing 21 to ensure the full condensation of high-temperature water vapor.

[0061] As Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the air outlet 203 is located on the side wall of the air duct housing 21 away from the washing cavity 101. Thus, the bottom wall of the air duct housing 21 can receive the excess condensed water that has not been discharged through the water outlet 204, preventing it from directly dripping to the ground outside the device through the air outlet 203.

[0062] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described.
