Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, specifically to a refrigerator with a one-star freezer compartment. Background Technology

[0002] Refrigerated refrigerators are a type of refrigerator with very high sales volume overseas. Refrigerated refrigerators have a 1-star freezer compartment (a 1-star freezer compartment usually means that its temperature should not be higher than -6℃). Such temperature conditions are suitable for short-term storage of frozen food, with a storage time of about 1 week. They can also quickly freeze food, making them convenient for users.

[0003] Most current one-star freezers use blown evaporators to create a freezing zone, simultaneously cooling the refrigeration zone. A new type of refrigerator with a one-star freezer compartment uses a single-piece inner liner to create a separate freezer compartment, achieving both refrigeration and freezing functions through a built-in evaporator.

[0004] Traditional refrigerators with a one-star freezer compartment use an inflatable evaporator to create a one-star freezer compartment. When using the refrigerator, food is placed directly on the inflatable evaporator, which is unsatisfactory in terms of both the appearance of the refrigerator and the user experience. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned above in the background technology and to propose a refrigerator with a one-star freezer compartment.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A refrigerator with a one-star freezer compartment includes an inner liner and an outer shell. A foam layer is disposed between the inner liner and the outer shell. An evaporator is disposed near the inner liner in the foam layer. Multiple independent evaporation tubes of the evaporator are attached to the outer surface of the inner liner. The evaporation tubes are flat in shape and have cavities inside.

[0008] As a further embodiment of this invention, the two independent evaporation tubes are interconnected by a connecting tube.

[0009] As a further embodiment of this utility model: a joint is welded to the side wall of the evaporator tube, and the connecting pipe is connected to the evaporator tube through the joint.

[0010] As a further embodiment of this utility model: the connecting pipe is threadedly connected to the evaporation pipe via a connector.

[0011] As a further embodiment of this utility model, the connecting pipe is welded to the evaporation pipe via a joint.

[0012] As a further embodiment of this utility model: the connecting tube is snapped into the evaporation tube via a connector.

[0013] As a further aspect of this invention: the cavity inside the evaporator tube is used to contain refrigerant for heat exchange within the evaporator tube.

[0014] As a further embodiment of this utility model: a first cavity and a second cavity are formed inside the inner liner, and the first cavity is disposed above the second cavity.

[0015] As a further embodiment of this utility model: guide rails are formed on both sides of the inner wall of the second cavity of the inner liner.

[0016] As a further embodiment of this utility model, it also includes a refrigerator door, which is rotatably connected to the outer casing.

[0017] The beneficial effects of this invention are as follows: A refrigerator with a one-star freezer compartment uses an integrated inner liner design with a concealed evaporator. By placing the evaporator within a foam layer, the product's aesthetics and user experience are significantly improved. Because the evaporator is placed within the foam layer, it is not in contact with the outside environment during refrigerator use, thus greatly extending its service life. Problems such as evaporator corrosion and leakage will not occur. Attached Figure Description
