In view of the above, the following thawing methods are applicable to the prior art: at normal temperature, slowly thawing the food under the action of external air; the food is placed in a microwave oven and thawed by high frequency waves. However, in the process of slowly thawing frozen food at normal temperature, food is directly exposed to the outside, and thus the food is easily spoiled and is difficult to eat. In the process of thawing food by high frequency waves inside the microwave oven, the surface of the food is directly cooked due to the high frequency waves, thereby deteriorating the flavor of the food. In addition, in the conventional technology, the food needs to be taken out of the freezing chamber and moved to a place where the food is thawed, which increases inconvenience in user operation.
