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.

Embodiment Construction

[0031] like figure 1 As shown, the embodiment of the present invention provides a thawing device 10 . The thawing device 10 includes a radio frequency electromagnetic wave generating device 20 , a casing 100 , and a thawing chamber 302 inside the casing 100 for receiving objects to be thawed. The radio frequency electromagnetic wave generating device 20 is used for applying radio frequency electromagnetic waves to the thawing chamber 302 to thaw the object to be thawed in the thawing chamber 302 . The casing 100 has an electromagnetic wave shielding layer for preventing radio frequency electromagnetic waves from leaking out of the thawing chamber 302 .

[0032] The housing 100 has a vent 1001 communicating with the inside and outside of the thawing chamber 302 , and the size of the vent 1001 is designed so that radio frequency electromagnetic waves emitted into the thawing chamber 302 cannot pass through the vent 1001 .

[0033] The radio frequency electromagnetic wave gener...

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 ...
