Unfreezing device, refrigerator and work method of refrigerator

Abstract

One embodiment of the invention discloses an unfreezing device. The unfreezing device comprises a radio frequency electromagnetic wave generation device (20), a shell (100) and an unfreezing cavity (302) located in the shell (100). The shell (100) is provided with an electromagnetic wave shielding layer and is provided with a ventilation opening (1001) communicating with the interior and the exterior of the unfreezing cavity (302), and the size of the ventilation opening (100) is designed for not making radio frequency electromagnetic waves transmitted into the unfreezing cavity (302) penetrate the ventilation opening (1001). One embodiment of the invention discloses a refrigerator comprising the unfreezing device. Due to the fact that the ventilation opening with the certain size is formed in the shell, radio frequency wave radiation can be avoided while the unfreezing cavity communicates with the exterior of the cavity. Meanwhile, after a user uses the refrigerator for unfreezing anddoes not take unfrozen food in time, the food can be protected against deterioration.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a thawing device, a refrigerator and a working method of the refrigerator. Background technique [0002] With the development of home appliance cooking technology, more and more heating technologies are applied to different kinds of home appliances, especially refrigerators. The application of heating technology to refrigerators increases the diversity of refrigerator functions. For example, refrigerators can also realize functions such as defrosting. [0003] Usually, microwave ovens are used to thaw at home, but there are problems such as uneven thawing and local overheating when thawing in microwave ovens. There are also some thawing devices installed in the storage room of the refrigerator. There are problems in this way. For example, after the thawing is completed, the user does not take out the thawed food in time, and long-term storage will cause the food to ...

AI Technical Summary

Problems solved by technology

[0003] Generally, microwave ovens are used to thaw at home, but microwave thawing may cause problems such as uneven thawing and local overheating.

There are also some thawing devices installed in the storage room of the refrigerator. There are problems in this way. For example, when the thawing is completed, the user does not take out the thawed food in time, and the food will deteriorate if left for a long time.
