Description

Freezer

Technical field

The utility model relates to the field of refrigeration technology, in particular to a refrigerator.

Background technique

At present, there are a lot of frost problems in direct-cooling freezers. One of the reasons is that when the cabinet door is opened and closed, the moist air enters the interior and encounters cold condensation and frost. Another important factor is: when the compressor is turned on and off, the pressure inside and outside the cabinet is generated. The humid air outside the cabinet enters the cabinet through the door crack, and then the humid air is pre-cooled and condensed into frost.

A commonly used method in the industry to reduce the amount of frost in the freezer is to open a hole at the mouth of the freezer, use a ventilation pipe to connect it to the outside world, and set up a low-frost module in the middle. The low-frost module is cooled by the low temperature of the inner tank, thereby reducing the temperature in the air. Moisture condenses and reduces the proportion of humid air entering the cabinet, thereby achieving the purpose of defrosting. In order to achieve the purpose of fully condensing water vapor, the low-frost module is equipped with fins, but this method still has the problem of incomplete condensation.

In view of this, it is necessary to design a new refrigerator to solve the above problems.
