The invention discloses a refrigerating and freezing integrated simple return air channel device. The middle of an air channel body is provided with an air inlet. One surface of the air channel body is provided with a first mounting groove. The two sides of the bottom surface of the first mounting groove are provided with first air channels correspondingly. The lower ends of the first air channelsare provided with first return air inlets. The other surface of the air channel body is provided with a second mounting groove. The two sides of the bottom surface of the second mounting groove are provided with second air channels. The lower ends of the second air channels are provided with second return air inlets. A first air channel cover plate is mounted in the first mounting groove. A second air channel cover plate is mounted in the second mounting groove. According to the refrigerating and freezing integrated simple return air channel device, the air channel body, the first air channelcover plate and the second air channel cover plate are arranged to form the integrated simple return air channel device. The refrigerating and freezing integrated simple return air channel device issimple in structure and easy to assemble and has the advantages of being low in cost and high in assembly efficiency, substantially reducing the tooling charge of parts and the like. The air inlet penetrates through the air channel body, the design of the refrigerating air channel is simplified, and the air inlet efficiency of a refrigerating chamber can be improved.
