Description

Drawer type disinfection cabinet

Technical Field

The invention relates to the technical field of kitchen equipment, in particular to a drawer type disinfection cabinet.

Background

The existing disinfection cabinet generally comprises a cabinet body with a disinfection cavity and a drawer capable of entering and exiting the disinfection cavity, wherein the drawer generally comprises a hollow pull basket, and tableware is placed in the pull basket combined by a plurality of metal strips. When tableware needs to be placed in the pull-out basket, the drawer is opened firstly, the pull-out basket is exposed, and then the tableware which is just cleaned is placed in the pull-out basket. The dishes are usually placed vertically in the baskets so that the water on the surface of the dishes drips under the action of gravity and dries the surface of the dishes. Because the surface of the tableware which is just cleaned is provided with water, when the tableware is just placed on the pull basket and the drawer is not closed, the water can drip on the ground through the hollow parts on the pull basket to wet the ground, so that the ground is wet and slippery, and potential safety hazards are brought; meanwhile, the moisture can adsorb dust, and the toilet is unsanitary.

In order to solve the above problems, a disinfection cabinet disclosed in the utility model patent with the patent application number CN200420021454.9 (publication number CN2699883Y) comprises a housing, a disinfection device, a drawer and a drawer type water pan arranged at the bottom of the disinfection cabinet. When the bowl and the dish are placed, water dropping from the bowl and the dish can be received by the drawer type water receiving tray, so that the ground can be prevented from being wetted and polluted.

However, for the existing water pan including the above scheme, the opening and closing of the water pan requires manual driving by a user as required, which is inconvenient, the drawer and the water pan cannot move synchronously, and the water pan cannot be automatically opened and closed according to the opening and closing state of the drawer.
