[0001] The utility model relates to the technical field of household appliances, and particularly relates to a water-proof folding door and a household appliance. Background Art
[0002] The door body of a household appliance usually adopts a drawer-type panel. For example, in a dishwasher and a disinfection cabinet, the panel is connected to a bowl basket. Guide rails are provided on both left and right sides of the bowl basket. The panel and the bowl basket are assembled into a drawer to be pulled in and out of the inner cavity of the household appliance. Or, the door body of the household appliance is turned up and down on the household appliance body. The door bodies of the household appliances with the above two structures occupy too much space outside the household appliance when in an open state. Therefore, a folding door applied to a household appliance needs to be designed. However, the folding door is composed of two hinged door bodies, and there is an opening and closing gap at the hinged part of the two door bodies. When the folding door is closed on the household appliance, liquid will leak out of the folding door through the opening and closing gap. Therefore, a water-proof folding door needs to be designed.
