When the refrigerator 100 starts to operate, the compressor compresses the refrigerant to enter the evaporator 3, the evaporator 3 starts to supply cold energy to the inner case 12 of the refrigerator 100, and the temperature inside the inner case 12 is lowered to maintain the articles to be stored at a low temperature inside the inner case 12.

The switch for opening or the fan 5 is arranged on the front side surface of the outer box body 11, a user can take down the heat preservation cover 8 firstly to enable the cold air outlet 111 to be in an open state, then the switch of the fan 5 is started to enable the fan 5 to rotate, the fan 5 rotates to form low pressure around the air cooler 7, air flow enters the inner ring layer 46 from the air inlet channel of the air inlet support 4 and is changed into cold air flow after heat exchange with the air cooler 7 is carried out. The cold ware 7 that looses adopts high thermal conductivity coefficient material to make, and looses the cold ware 7 and press close to evaporimeter 3 setting, can absorb the partial cold volume of evaporimeter 3 fast, looses the temperature reduction of cold ware 7, when centrifugal fan 5 began work, scattered cold ware 7 around form the negative pressure, outside air passes through inlet channel 43 this moment and gets into in the wind channel switching portion 6 to see off the inside cold air of cold ware 7 that looses from cold air outlet 111. Because the air diffuser 7 has a plurality of cooling fins 72, when air enters the periphery of the air diffuser 7, the air can be in large-area contact with the plurality of cooling fins 72, the temperature of the air flow is rapidly reduced to form a cold air flow, and the cold air flow is blown out from the cold air outlet 111.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all 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.
