Description

An air-cooled multi-door freezer

technical field

The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator for low-temperature preservation of articles.

Background technique

As a convenient refrigeration tool, the freezer is widely used in commercial and household fields. The horizontal freezer is a common type of freezer, because its depth is generally deep, and it is difficult to pick and place items. Traditional refrigerators mainly solve the problem of difficulty in picking and placing items by setting top-opening doors on the top and setting drawers on the front, and adopting a full-wound tube refrigeration structure. However, the full-wound tube refrigeration structure has problems such as serious frosting, laborious opening of the door, easy leakage of the drawer, and freezing. The user can only take out the items in the freezer and turn off the power of the freezer to defrost. In addition, the pressure difference between the inside and outside of this kind of freezer is relatively large, and it is quite laborious for the user to open the door twice when using it.

At present, the frost-free freezer achieves frost-free by adopting a single compartment structure, setting the refrigeration system on one side, and extending the air duct on both sides to supply air. However, the setting of a single compartment results in a deep freezer, making it difficult to pick and place items inside. At the same time, frost-free freezers are limited to refrigerated/freezer conversion cabinets, and the entire freezer can only be used as a refrigerator or a freezer, which has poor flexibility and is difficult to better meet the storage needs of customers.

Through patent search, there are the following known technical solutions:
