According to the fourth design of this application, set up the fan in the wind channel, the in-process that unfreezes to food at the electromagnetic wave, must have the heat production, and the heat can spread in the storeroom, influence the cold-stored effect of storeroom, consequently set up the wind channel and make food cavity and refrigerator outside intercommunication, and set up the fan, the speed of the flow direction of drive heat dissipation air current has further improved the radiating efficiency, the heat that makes food process of unfreezing produce is along with the air current discharges to the refrigerator outside.

According to the fifth concept of the present application, a heat conducting member is further disposed in the thawing chamber, and the heat conducting member is disposed outside the rear wall of the thawing chamber or inside the heat dissipation air duct.

According to the sixth concept of the present application, at least a portion of the casing of the thawing chamber is made of a metal material for improving the heat conduction effect, in an embodiment of the present application, the rear wall of the thawing chamber and the side walls on both sides of the food chamber are made of metal materials, so as to improve the efficiency of discharging the heat in the air guide channel and the heat in the tuning chamber out of the thawing chamber and the efficiency of entering the air guide channel by the heat in the food chamber.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
