Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] In the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediary, and it can be the internal communication of two components.

[0029] In order to solve the problem that the door of the refrigeration device is prone to being unable to open, and the existing solutions to prevent the door from...

Abstract

The invention relates to the technical field of refrigeration, in particular to an air pressure balance structure for a refrigeration device and the refrigeration device. The inner end of an airflow pipe of the air pressure balance structure is communicated with a refrigeration cavity of the refrigeration device, the outer end of the airflow pipe is communicated with the environment, a fan is arranged in the airflow pipe, and the rotation surface of the fan is disposed in the airflow direction in the airflow pipe. The air pressure balance structure is arranged in a box door of the refrigeration device. When a refrigerator performs refrigeration, due to temperature changes, external airflow enters a box body through the airflow pipe, and the fan is driven to rotate. In the process, when internal and external pressure difference of the refrigeration device (such as the refrigerator) is large, the rotating speed of a fan rotor is accelerated, the internal and external pressure difference of the refrigerator can be quickly reduced; during a normal state, the internal and external pressure difference of the refrigerator is small, a rotating force of the fan rotor is weak, the fan rotor almost does not rotate, the fan rotor and the outer end of the airflow pipe form a relatively sealed environment, and cool air leakage is avoided. The air pressure balance structure is simple in overall structure, the internal and external pressure difference of the refrigerator can be quickly reduced, and conditions that it is difficult to open a refrigerator door of the refrigerator are avoided.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an air pressure balance structure for refrigeration devices and the refrigeration device. Background technique [0002] After the freezer is opened, the hot air entering the freezer will contract when it is cold. After the air shrinks, the air pressure will decrease to a certain extent. For this reason, the main solution at present is: way one, air vent is punched on the door seal of freezer, as the freezer disclosed by CN103471327B; It can well balance the pressure difference between the inside and outside of the freezer; the large air holes can easily cause serious frost in the freezer, and the air flow rate cannot be adjusted according to the pressure difference between the inside and outside. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide an air pressure balance structure and a refrig...
