Problems solved by technology

However, there is a disadvantage in this method of increasing air holes: the air holes will keep the air inside and outside the freezer in a conduction state, so that the cold air in the freezer will always be in a state of leakage, resulting in energy loss; During the process, it is easy to cause frost at the position of the air hole, which affects the convenience of the user

Abstract

The invention relates to the technical field of refrigeration equipment, in particular to a structure for reducing negative pressure in a box of a refrigerator, a refrigerator door body and the refrigerator. The structure for reducing the negative pressure in the box of the refrigerator comprises a refrigerator door body liner body, installation grooves are formed in the periphery of the refrigerator door body liner body, and air pressure balancing air guide grooves are formed in the installation grooves. Door sealing strips are arranged on the periphery of the refrigerator door body liner body. The extending ranges of the air pressure balancing air guide grooves are larger than the abutting-joint width ranges of the refrigerator door body linear body and the door sealing strips. The faces, facing the refrigerator door body liner body, of the door sealing strips are provided with installation parts, the installation parts are inserted into the installation grooves, wing sides are arranged on the two sides of the installation parts and are in interference fit with groove walls of the installation grooves, and the parts, located in the installation grooves, of the air pressure balancing air guide grooves pass through the abutting-joint positions of the wing sides and the groove walls of the installation grooves. The structure for reducing the negative pressure in the box of the refrigerator has the beneficial effects that the structure is simple, generation of the negative pressure is avoided, and the requirement of users in different regions for product convenience can be met.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a structure for reducing negative pressure in a refrigerator, a door body of the refrigerator and the refrigerator. Background technique [0002] During the use of the freezer, due to the cooling effect inside the freezer, the temperature inside the freezer decreases, which reduces the air pressure inside the freezer, causing the air pressure inside the freezer to be lower than the outside air pressure of the freezer, resulting in negative pressure, which makes it difficult to open the door of the freezer. In the prior art, in order to avoid negative pressure inside the freezer, the common method is to add ventilation holes on the door seal on the inner liner of the freezer door, and conduct the air inside and outside the freezer through the door seal to achieve the balance of air pressure inside and outside the freezer. Thereby avoiding the generation of negative...
