Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, and specifically refers to a cleaning machine for cleaning tableware and fruits and vegetables. Background Art

[0002] During the cleaning process of the dishwasher, at least one water flow is hot water, and a large amount of wet and hot steam will be generated during the washing process. After this water flow is used for cleaning, the wet and hot steam needs to be discharged before the next water flow is used for cleaning.

[0003] The Chinese patent application "A Drying Device of a Cleaning Machine and Its Drying Control Method" with the application publication number CN115067849A discloses a structure in which an exhaust assembly is provided on the door body for discharging the wet and hot steam in the washing cavity. The air inlet of this exhaust assembly is located on the inner surface of the door body, and an ordinary nut is used for connection at the air inlet, which is in an open state.

[0004] The following problems exist in the above structure:

[0005] (1) During the washing process, due to the relatively high pressure in the washing cavity, the wet and hot steam will be discharged through the nut and the exhaust assembly, resulting in steam leakage and affecting the washing environment in the washing cavity;

[0006] (2) The open channel is likely to form condensed water during the washing process. The condensed water hangs on the inner wall of the air duct, and when exhausting air formally, the condensed water is discharged concentratedly and is likely to drip onto the floor, affecting the user experience;

[0007] (3) In different cleaning modes, for example, during ultra-clean washing, the temperature in the washing cavity is relatively high and the water volume is relatively large, which is very likely to cause excessive steam. After the washing is completed, rapid exhaust is required; while during gentle washing, the temperature in the washing cavity is relatively low, the water volume is relatively small, and the generated steam is also less. Excessive rapid exhaust will instead cause the temperature in the washing cavity to drop too fast, which is not conducive to the cleaning effect of the next step; however, currently, the flow area of the exhaust air duct is fixed and cannot meet the above targeted requirements;

[0008] (4) After the cleaning is completed, if the exhaust air duct is not closed, external insects or cockroaches may enter the dishwasher, affecting the environment in the washing cavity. Summary of the Utility Model
