Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention provides a refrigerator that more completely seals between the doors.

[Background of the invention]

In conventional refrigerator door seals, the sealing backing had a single shape formed by extrusion molding or the like, so there were concerns about the sealability of the corners. Also, since the seal backing was single-layered, there was a defect that the sealing performance deteriorated during long-term use.

[Purpose of the invention]

The present invention provides a method for sealing corners when directly sealing between doors, and a method for maintaining complete sealing performance even after long-term use.

[Summary of the invention]

That is, a sealing backing is provided at the lower edge of the upper door and the upper edge of the lower door, soft corner backings are provided at both ends of the sealing backing, and an internal backing is provided on the inside of the sealing backing. It is a double seal.

[Embodiments of the invention]

Hereinafter, the details of the present invention will be explained with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a refrigerator main body, and its front face C1 (has an upper door 2 and a lower door 3 at the opening; the lower edge of the upper door 2). The lower door 3 is provided with a seal backing 4 that contacts and seals with the seal backing 5 described later, and the upper edge of the lower door 3 is provided with a seal 5 that contacts and seals with the seal backing 4 of the upper door.Seal As shown in FIG. and the lower edge thereof are made of a soft sealing material 5b as shown in FIG.
Soft corner backing 5 at both upper corners of the part and part 5b
It has a C part. Soft corner backing 5C is No. 8
As shown in the figure, one end Q is connected to a soft sealing material 5b by welding or the like, and the other end R is in close contact with a hard sealing material 5a. Reference numeral 6 denotes a stopper for more firmly bringing the corner backing 5C into close contact with the hard sealing material 5a, and screws 8 fix the corner backing 5C to the sealing material 5a. Reference numeral 7 denotes an elastic body fitted to the stopper 6, which prevents the corner backing 5C from deforming due to external force during long-term use. 9 is a throat 9 provided on the inside of the upper edge of the sealing part 1 and the sealing 5;
0 and is in contact with the soft seal portion 13a of the internal backing 13 for sealing. Both ends of the throat 9 fit into the protrusions T of the corner backing 5C. As shown in FIG.
2, and the fin 4f at the other end is fitted by the throat 10 and the throat stand 11. On the inside of the refrigerator body 1, there are 5cl of seal backing 5 and seal backing 4.
It has a seal portion 1a that can be sealed by contact. 14.1
5 is a food storage container attached to the inside of the upper and lower doors.

Reference numeral 16 denotes a thin plate that prevents water that evaporates from the vegetables from adhering to the bottom of the upper container 14 when the vegetables are stored in the container 15.

〔Effect of the invention〕

As explained above, the present invention is such that the lower edge of the upper door and the lower edge of the lower door are brought into contact and sealed by the seal backing 4 and the seal backing 5, and the internal backing 13 is also placed on the inside of the refrigerator. Since it is placed in the .5 section, it becomes a double seal, and even if a small crack or the like occurs in the seal backing during long-term use, the sealing performance can be maintained. Furthermore, since the seal backing 4 has one end 4e fixed with a stopper and the other end fin 4f fitted through the throat 10, there is no friction between the seal backings when opening and closing the upper and lower doors. It can endure for a long time. In addition, a soft corner backing 5C is provided at the corner of the seal backing, and the corner backing 5C comes into close contact with the seal portion 1a of the refrigerator body, and the seal material 5 on the side edge
Since the sealing material 5a on the upper edge is connected integrally or separately to the sealing material 5a on the upper edge, it is possible to more completely maintain the sealing performance at the corner, which was conventionally considered to have poor sealing performance.
