After the installation is completed, a space between one side of the refrigerating air duct cover plate 90 and the inner container 200 is a refrigerating air path.

It should be noted that the ice making air duct and the ice making chamber are both disposed inside the inner container 200, the air inlet duct and the air return duct are disposed outside the inner container 200, and the air inlet duct and the air return duct are disposed in the foaming layer between the inner container 200 and the housing, which enables the ice making machine to have a more compact structure and a smaller occupied space.

Finally, it should be noted that: the above embodiments are merely illustrative of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications and equivalents may be made to the technical solutions of the present application without departing from the spirit and scope of the technical solutions of the present application, and the technical solutions of the present application should be covered by the claims of the present application.
