Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

A refrigerator door structure, door drain pan 10 is including covering the basal portion of locating the refrigerator body top, the bottom of basal portion holds the intracavity to the refrigerator and stretches the protruding portion 11 that constitutes, and the lateral wall that protruding portion 11 held the chamber lateral wall with the refrigerator and constitutes sealed cooperation. When the refrigerator door body is covered, the protruding part is embedded into the refrigerator body and forms sealing fit with the inner wall of the refrigerator body in the circumferential direction, so that the refrigerator door body is tightly connected with the refrigerator body, and the refrigerator door body and the refrigerator body cannot be separated due to bumping when a vehicle runs. The sealing surface of the refrigerator door body and the refrigerator body is positioned in the refrigerator body and is integrally and horizontally arranged, the sealing performance is good, the base part of the door body bottom shell 10 is abutted against the top end face of the refrigerator body in a matched or clearance fit mode, the gas in the refrigerator body can be further prevented from dissipating, the sealing performance is guaranteed, and therefore the energy consumption of the refrigerator is reduced.

As shown in fig. 2, 3 and 6, a sealing ring 20 is attached to the periphery of the protruding portion 11, and the ring surface of the sealing ring 20 facing the side wall of the refrigerator cavity is in surface sealing fit with the side wall of the refrigerator cavity. Namely, the vertically arranged circumferential side wall of the sealing ring 20 faces the side wall of the refrigerator accommodating cavity, and the two are in sealing fit. The specific scheme is that a convex part 21 protruding outwards is arranged on the ring surface of the sealing ring 20 facing the side wall of the refrigerator accommodating cavity, and the refrigerator door body covers the convex part 21, so that the convex part 21 is extruded by the side wall of the refrigerator accommodating cavity to form surface sealing fit.

In order to ensure the reliable connection between the sealing ring 20 and the bottom case 10 of the door body and prevent the sealing ring 20 from being separated from the bottom case 10 of the door body when the door body is opened and closed, the sealing ring 20 is sleeved on the outer side of the positioning ring 30, and the positioning ring 30 is connected with the bottom case 10 of the door body. As shown in fig. 2 and 3, the positioning ring 30 includes a ring plate 31 engaged with the bottom wall of the protrusion 11 and a standing plate 32 engaged with the side wall of the protrusion 11, and the ring plate 31 is connected with the door base 10 by screws. The inner ring of the sealing ring 20 extends towards the space between the ring plate 31 and the door body bottom shell 10 to form a first flanging 22, and the outer ring extends towards the vertical plate 32 and the door body bottom shell 10 to form a second flanging 23; the ring plate 31 is connected with the door body bottom shell 10 to be extruded and position the first flanging 22 and the second flanging 23. Therefore, the inner and outer ring edges of the sealing ring 20 are extruded and fixed between the positioning ring 30 and the door body bottom shell 10, holes for connection do not need to be formed in the ring body of the sealing ring 20, the integrity of the sealing ring 20 is good, the sealing effect is good, and the appearance is high.

The top end of the vertical plate 32 is provided with an outward or inward folded plate 321, the plate body of the folded plate 321 is arranged in parallel with the plate body of the ring plate 31, and the second flanging 23 is clamped between the folded plate 321 and the door body bottom case 10. As shown in fig. 3, when the ring plate 31 is connected to the door bottom case 10, the ring plate approaches the door bottom case 10, the pressing and adhering surface between the folded plate 321 and the second flanging 23 is larger, and the clamping effect on the second flanging 23 is better.

In order to ensure the flatness of the inner surface of the refrigerator door body and improve the aesthetic appearance, the periphery of the protruding part 11 on the bottom shell 10 of the door body is recessed towards the inner side of the door body to form a concave part for accommodating the positioning ring 30 and the sealing ring 20, and the concave part comprises a concave platform 111 at the bottom wall of the protruding part 11 and a groove 112 at the base part of the protruding part 11; the first flanging 22 is attached to the table wall 111a of the concave table 111, and the second flanging 23 is attached to the groove bottom wall 112a of the concave groove 112.
