They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific direction structure and operation. Therefore, they cannot be understood as a limitation on the present invention.

[0027] In addition, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0028] See also Figure 1 As shown, the present invention provides a refrigerator inflation evaporator fixing structure, which includes at least an integrally injection-molded base 1, a support portion 4, and a snap portion 5. The integrated design reduces the number of parts, unifies the inflation evaporator 8 fixing structure into one, and optimizes the parts.

[0029] In one embodiment, the base 1 is circular, a boss 2 is provided at the center of the base 1, and a screw hole 3 is provided at the center of the boss 2.
