Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The present invention aims at the problem of cold leakage in the equipment for keeping the internal and external pressure balance of the current freezer, especially the ultra-low temperature medical freezer, which leads to the problem of poor refrigeration effect, and provides a device for maintaining the pressure balance inside and outside the freezer, which can adjust the pressure inside and outside the freezer in real time. And it seals well. Specifically, a device for maintaining pressure balance inside and outside the refrigerator includes a vent pipe and a one-way valve, and one end of the vent pipe is connected to the one-way valve.

[0033] refer to figure 1 and figure 2 As shown, a device for maintaining pressure balance inside and outside the refrigerator includes a vent pipe 1 and a one-way valve 2, and one end of...

Abstract

The invention provides a device for maintaining balance of inner pressure and outer pressure of a refrigerator, an installation method and the refrigerator. The device comprises a vent pipe and a one-way valve. One end of the vent pipe is connected with the one-way valve. The invention further provides the installation method of the device and the refrigerator. The device for maintaining the balance of the inner pressure and the outer pressure of the refrigerator can guarantee the balance of the inner pressure and the outer pressure of the refrigerator in real time, and does not need to be operated by manpower, sealing is guaranteed at the same time, cold leakage is avoided, the refrigerating effect is guaranteed, cost is low, the structure is simple, and replacement is convenient.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a device for maintaining pressure balance inside and outside the refrigerator, an installation method and the refrigerator. Background technique [0002] During the use of the medical freezer by the user, as the temperature inside the box decreases, the air pressure inside the box decreases, which is lower than the atmospheric pressure outside the box, resulting in a difference in the internal and external air pressure acting on the door. Therefore, when the user opens the door Difficult, especially the ultra-low temperature freezer, the lowest temperature in the box can reach minus 86 degrees Celsius. In extreme cases, users need tools to open the door, so it is necessary to install a device on the freezer to maintain internal and external pressure balance, so that the door body can be opened easily. Although the existing methods for maintaining internal and ex...
