Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a washing machine used for washing tableware, fruits and vegetables. Background Art

[0002] A dishwasher is a household appliance used for automatic dishwashing, which is very popular among consumers. However, after washing, there is a lot of residual water in the inner tank and on the dishes. This residual water is dried by the residual heat of the inner tank and the dishes. However, due to the large amount of residual water in the inner tank and the rapid cooling of the inner tank, the residual heat of the inner tank is not enough to evaporate the residual water, so there is still a lot of water in the inner tank for a long time after washing the dishes. If the dishwasher door is closed for a long time, the odor in the dishwasher will be strong and bacteria will easily breed.

[0003] In response to the above problems, the Chinese utility model patent with patent number CN201820319612.0 (publication number CN208958049U) discloses a "drying system for a dishwasher", including an inner tank and a breather, the breather is arranged outside the inner tank, the breather is provided with an exhaust channel, the exhaust channel connects the inside and outside of the inner tank, and also includes a hot air generating device, the hot air generating device is provided with a hot air output end, the hot air output end is connected to the inside of the inner tank, the inner tank is provided with an air duct nut corresponding to the hot air output end, the air duct nut fixes the hot air output end to the inner tank wall, the air duct nut is provided with a hole position, the hole position is connected to the inside of the inner tank and the hot air output end, the hole position includes a central hole and peripheral holes, and the peripheral holes are evenly distributed in a ring shape around the central hole.

[0004] For the above structure, the air supplied to the box body relies on convection for diffusion. However, since the heated air tends to float up after passing through the box body, and the water return area and spray arm of the cleaning machine are located at the bottom of the box body and are very likely to have residual water stains, the natural convection blowing method is prone to drying dead corners, resulting in poor drying effect. Utility Model Content
