Description

Exhaust Drying System for Dishwashers

technical field

The utility model relates to the field of dishwashers, in particular to an exhaust drying system for dishwashers.

Background technique

Due to the particularity of the household dishwasher as a water-washing product, to make the tableware dry quickly after washing, it is necessary to discharge the high-temperature and high-humidity steam inside the dishwasher cavity to the outside of the cavity.

The current methods of dishwashers on the market to quickly dry tableware include: 1. Open an air port on the cavity to let the hot and humid air discharge by itself. Due to the slow air flow, the drying effect of the tableware is poor in this solution; 2. The exhaust fan quickly draws the hot and humid air out of the cavity. The air outlet of this solution is located on the side or back of the cavity. For the model embedded in the cabinet, the moisture will be difficult to discharge in the cabinet and wet the cabinet. The patent document whose application number is 201620418562.2 discloses an exhaust device for a dishwasher and the dishwasher, and the patent document whose application number is 201620418425.9 discloses an exhaust device for a dishwasher and a dishwasher. There are two exhaust devices The problem is that one is that the air duct is a circuitous air duct in the door body, which greatly reduces the wind speed and the effect of the draft. The second is that the exhaust port is set on the handle in front of the door body, which is a place where the user is likely to touch or get close. High-temperature steam is discharged here, which poses a great safety hazard. Moreover, condensed water will flow out of the air outlet, which gives users a very bad impression.
