Abstract

The invention discloses a door body with an air pressure balance function, and refrigerating equipment. The door body with the air pressure balance function comprises an insulation door and a handle; a ventilation pipe is arranged in the insulation door; the handle is provided with a valve for opening and closing an outer pipe orifice of the ventilation pipe; an elastic air cavity is formed in the inner surface of the insulation door; and an inner pipe orifice of the ventilation pipe communicates with the elastic air cavity. The requirement of reaching internal and external air pressure balance of a box body during opening of the door is realized; the internal frosting of the box body caused by air pressure balance is reduced; and the user experience is improved.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a door body with air pressure balance function and refrigeration equipment. Background technique [0002] At present, the insulated boxes used for refrigeration equipment (refrigerators, freezers, etc.) usually include a box body and a door body. , so that when the door is opened, it is difficult to open the door due to the negative pressure inside the box. Chinese Patent No. 201510788863.4 discloses a door body and a refrigerator. Specifically, it discloses that a ventilating pipe connecting the inside and outside of the box is formed on the door body, and the opening and closing of the ventilating pipe is controlled by a handle assembly on the door body. However, in actual use, after the handle assembly opens the vent pipe so that the inside and outside of the box are communicated, outside air enters into the box and easily generates frost in the box. How to design a refrigeration d...
