Freezer

Abstract

The invention relates to a refrigeration device comprising the following members: a box body with an inner container used for limiting a storage space; a door body pivoted to the box body so as to open and / or close at least partial the storage space; a defrost mechanism arranged on the inner side of the door body and used for scrapping at least partial the inner container in a door body opening and / or closing process, thus removing at least partial the frost on at least partial the inner container. The refrigeration device can carry out defrost operations in each door body opening and closing process, thus scrapping off the frost on the inner container before the frost is solid, and solving the technical problems that the solid frost on the inner container of the refrigeration device cannot be easily removed; in addition, the complex defrost process can be resolved into normal door opening and closing processes, so users need no extra defrost operation; the refrigeration device is simple in application and low in cost.

Description

technical field [0001] The invention relates to refrigeration and freezing technology, in particular to a refrigeration and freezing device. Background technique [0002] After using direct-cooling refrigerators, freezers and other refrigerating and freezing devices for a period of time, the moisture in the air will frost on the inner wall of the refrigerating and freezing device, and the longer the time, the thicker the frost will be, which will reduce the heat transfer efficiency of the inner tank. decrease, seriously affecting the user experience. Therefore, the user needs to manually defrost regularly, which seriously affects the user experience. [0003] In order to solve the above-mentioned technical problems, a kind of refrigerating and freezing device with a scraper portion on the storage container inside has appeared in the prior art. A portion of the inner tank is frosted, so that the user does not need to manually defrost it deliberately. However, the scraper p...

AI Technical Summary

Problems solved by technology

However, the scraper portion is arranged on the storage container placed in the refrigerating and freezing device, and can only defrost the side wall of the inner container; , the defrosting effect is very inconspicuous; and if the storage container has not been taken out for a long time, the scraper part is very easy to freeze with the inner wall of the tank, resulting in the failure to take out the storage container normally
