Background
In general, a refrigerator has a refrigerating chamber storing food at a low temperature above zero and a freezing chamber freezing food at a low temperature below zero. The interior of the freezing chamber is generally used for storing meat, instant foods and long-term foods. After the user takes out the food stored in the freezing chamber, the food needs to be thawed and then eaten.
If the frozen food is directly cooked, the interior is not cooked even if the surface of the food is already cooked, and thus the taste of the cooked food may be affected. As described above, the taste of frozen foods after cooking is drastically reduced due to the frozen storage itself. In view of such problems, thawing is generally performed before frozen foods are cooked.
In addition, in the thawing process of foods as described above, most important is: the inside and outside of the food are completely thawed, and the thawing process can be rapidly performed, so that the user can eat rapidly. In view of the above, the thawing method applied in the past is: the food is slowly heated by the external air at normal temperature; or thawing the food in water; or placing the food into a microwave oven, and thawing with low-output high-frequency wave.
However, frozen foods are easily rotted due to exposure to air during slow thawing at normal temperature, resulting in a problem of inedibility. The thawing speed can be increased to a certain extent by putting food into water, however, the thawing speed still cannot meet the demands of most users, and the taste of the food is affected by putting the food into water, so that the nutrition of the food is lost. The food can be thawed by utilizing high-frequency waves in the microwave oven, but the penetration capacity of the microwaves is limited, so that the local temperature of the food is rapidly increased, the surface is rapidly thawed and even is well-done, the interior is still in a frozen state, and the taste of the food is also influenced.
In view of this, there is a need for an improvement of the existing thawing apparatus to solve the above-mentioned problems.
