[0002] At present, with the continuous improvement of people's living quality, dishwashers have gradually become a commonly used household appliance, mainly used for cleaning and drying tableware such as bowls and plates. Using a dishwasher to wash tableware can greatly reduce the cumbersome manual labor. Just put the tableware to be washed into the dishwasher, turn on the faucet, and press a button, and you can rest assured to do other things, because no one needs to wait during the washing process and the operation can be automatically completed. The dishwasher reduces people's labor intensity and improves work efficiency.

[0003] For a drawer dishwasher having a housing and a drawer that can be pulled out and arranged inside the housing, a door panel is provided at the front end of the drawer. The door panel generally needs to be fixed to the front end face of the drawer by screws; fixing by screws has good firmness, but the door panel is an appearance part of the dishwasher, and the screws can only be arranged on the left and right sides of the door panel. Therefore, side plates extending backward are provided on the left and right sides of the door panel for fixing the door panel to the drawer by screws and increasing the sense of massiveness of the appearance of the door panel; however, after the side plates are provided, there is a relatively large distance between the front end face of the door panel and the front end face of the drawer, so that the door panel cannot be supported by the front end face of the drawer, resulting in the door panel being concave and deformed after being stressed and affecting the firmness of the door panel fixation.
