Freezer

Abstract

The invention relates to a freezer comprising a balance valve, a defrosting pipe and a frost collection box, wherein the balance valve and the defrosting pipe are arranged on the freezer, and the frost collection box is connected with the balance valve and the defrosting pipe. The balance valve is of a one-way valve type and is arranged on a freezer body, and the inside and the outside of the freezer can be communicated through the balance valve. The frost collection box is arranged in the freezer body of the freezer. A freezer body inside outlet of the balance valve faces towards the inside of a box body of the frost collection box. The defrosting pipe comprises a dehumidification pipe filled with desiccant. A waterproof gas-permeable film is arranged inside the defrosting pipe and located at the position, close to the inner side of the freezer body, of the defrosting pipe. The defrosting pipe is installed on the freezer body and connected with the frost collection box. A freezer body inside outlet of the defrosting pipe faces towards the inside of the frost collection box. According to the freezer, on the premise of balancing air pressure inside the freezer body and outside the freezer body, the frosting amount of an inner container of the freezer body is reduced, and therefore the cycle of removing frost is prolonged.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a frost preventing and reducing device for the refrigerator. Background technique [0002] Direct cooling freezer products are refrigerated by the evaporator or plate tube evaporator. Frost usually forms quickly on the inner wall of the evaporator or the plate tube evaporator. Part of the water vapor that forms the frost comes from the stored food, but more Most of them come from the water vapor leaked from the door seal. The fluctuation of the temperature inside the box caused by the start and stop of the compressor will continue to cause the air pressure in the box to change continuously relative to the outside world, so that the water vapor from the door seal will continue to leak in, while the traditional Balanced vent holes in the door seal for easy door opening aggravate the frosting process. At the same time, the user often opens and closes the door during use. After the door is closed, ...

AI Technical Summary

Problems solved by technology

The inner tank is made of iron, which has low heat transfer efficiency and high power consumption

Moreover, this solution only facilitates the defrosting process, but cannot reduce the number of defrosting times, and cannot fully meet the needs of users, and the cost of this module is also relatively high
