Refrigerating equipment

Abstract

The invention provides refrigerating equipment. The refrigerating equipment comprises a door body, a door liner, a door seal and a door shell, wherein one part of the door seal and at least one end ofthe door liner form a door liner insertion groove; the door shell is opposite to the door liner; one end of the door shell is bent to extend into the door liner insertion groove; the door shell and the door liner surround a door body cavity; the door seal is out of the door body cavity; and a sealing material is arranged between the door liner insertion groove and one end of the door shell. A connecting structure of the door shell and the door liner and a connecting structure of a box liner and box side plates in the refrigerating equipment are improved; the sealing performances of the connecting structures are improved, so that the door body cavity and a box cavity can be conveniently vacuumized, the possibility of maintaining the vacuum state of the door body cavity and the box cavity for a long time is improved, the use of polyurethane foaming materials is reduced or canceled, and the cost is reduced; the structure of the refrigerating equipment is simplified; and the shaping design flexibility of the refrigerating equipment is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration device. Background technique [0002] As a daily appliance used for food preservation, the core function of the refrigerator is heat insulation. At present, the insulation technology commonly used in refrigerators is polyurethane foam technology, such as figure 1 As shown, the polyurethane foam material is filled in the cavity of the refrigerator and the cavity of the door body. Filling each cavity of the refrigerator with polyurethane foam material requires special foaming equipment and materials, and special fixtures and equipment are needed for locking and foaming. The foaming process is complex and affected by temperature, and the injection volume needs to be adjusted regularly. The box body 14 and the door body 10 also need to be sealed to prevent the bubble liquid from leaking out. If the bubble liquid leaks out, it will be very difficult to clean; t...

Problems solved by technology

[0003] like figure 1 As shown, the door body 10 of the refrigerator includes a cavity surrounded by the door liner 100 and the door shell 102, and the box body 14 includes a cavity formed by the box liner 140, the side plate 142 and the back plate 144; figure 2 As shown, a groove is provided on the door liner 100, so that the pointed end of the door seal 104 can be inserted into the groove and fixed; in this structure, the door liner 100 overlaps with the door shell 102, and the door liner 100 and the door seal 104 is plugged in, and there is also an intersecting part between the door seal 104 and the door shell 102, the structure is complex, and it is not convenient for sealing; , but the tank connecting groove 146 formed by the side plate 142 through multiple bending is uneven, and the part of the tank 140 extending into the tank connecting groove 146 is also bent several times, and the tank 140 and the tank connecting groove 146 The side wall is in line contact, which is not convenient for sealing; similarly, if image 3 As shown, the connection between the side plate 142 and the back plate 144 of the refrigerator box 14 is connected through the back plate connecting groove 148, but the side plate 142 and the back plate 144 all need to be bent multiple times, and the process is complicated; When the plate connecting groove 148 is inserted, the insertion direction is perpendicular to the direction of the main body of the side plate 142, which may easily cause deformation of the side plate 142; and the gap between the side plate 142 and the back plate 144 is relatively large, making it difficult to seal
