Refrigerator with air pressure adjusting structure

Abstract

The invention discloses a refrigerator with an air pressure adjusting structure, and relates to the technical field of refrigerators. The refrigerator comprises a refrigerator body and a door body. The door body comprises a door shell, a door lining and a lower decorative strip. First air holes are formed in one surface of the door lining. Second air holes are formed in the lower surface of the lower decorative strip. A breather pipe is vertically arranged between the door shell and the door lining. The breather pipe comprises a first branch pipe and a second branch pipe. The lower end of thefirst branch pipe abuts against the upper end openings of the second air holes. The upper end of the first branch pipe is connected with the lower end of the second branch pipe. The outer wall of thesecond branch pipe is radially connected with a shunt pipe communicating with the second branch pipe. One end of the shunt pipe abuts against the inner end openings of the first air holes. A frost blocking part is arranged in the lower end of the first branch pipe. The frost blocking part is used for filtering water vapor in the external air when the external air enters the refrigerator body through the breather pipe. And a floating ball is arranged in the second branch pipe. By means of the refrigerator with the air pressure adjusting structure, the pressure difference between the inside andthe outside of the refrigerator can be effectively balanced, and the market application value is high.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a refrigerator with an air pressure regulating structure. Background technique [0002] At present, during the cooling process of existing direct cooling refrigerators / cabinets, negative pressure is often generated inside the refrigerator, and at the same time, frost will form on the inner liner of the refrigerator, which will make it difficult to open the door, and the frost will also affect the appearance, performance and quality of the refrigerator. At the same time, it also leads to frequent and cumbersome defrosting, which causes great inconvenience to the majority of users. In view of the above problems, in the prior art, it is often solved by strengthening the sealing of the door gap and adding a booster device for opening the door, but the improvement of the effect of this method is not obvious. Therefore, it is urgent to study a refrigerator with an air pressure r...
