Description

[Detailed Description of the Invention] In currently used refrigerators, a gasket is attached to the back side of the door (on the side of the refrigerator body) along the edge with screws or the like. The gasket attached to the door in this manner is attracted to the door by a rubber magnet inserted into the gasket, and airtightness is maintained. However, each time the door is opened, the gasket is pulled by the attractive force of the magnet, and as this process is repeated, a gap forms between the gasket and the door, allowing cold air to leak out of the refrigerator.

The present invention eliminates these drawbacks, and at the same time provides a refrigerator door edge sash that eliminates the step of attaching a gasket to the door during manufacture and allows easy attachment of a repair gasket.

The figure is a cross-sectional view of an embodiment of the edge sash according to the present invention, in which a frame portion l is made of a hard resin and has a U-shaped cross section in which one end side /a is longer than the other end side /b, and a frame portion l is made of a soft resin. It consists of a gasket s2.

The frame portion l has a groove /c on the end face of the other end side /b, and the cross section of the portion near the center side of the one end side /a is formed in the shape of a mouth;
The portion near the center side forms a four part/d when viewed from the outside, and the entrance of the four part/d is formed narrower than the width inside the recess.

The gasket part includes a cylindrical part 2a, an extendable part 2b, and a curved part 2b, Jc extending outward from both ends of one surface of the cylindrical part 2a.
, an enclosing part Kod formed to surround the outwardly curved part of the extensible part 2c, a fin part 2e branching from the middle of the enclosing part Jd and extending outward, and an enclosing part 2d. It consists of a base part f which connects the telescopic part C and the enclosure part d so as to form a sealed space between the telescopic part 2b and the telescopic part 2b. One end of the base part -f is integrally molded with the extension part on the side la, and one end of the base part -f is integrally molded with the outer corner part of the character arrangement part of one end side /a.

This edge sash can be obtained as an integral molded product by co-extruding the frame part l made of hard resin and the gasket part made of soft resin, and then cut diagonally to a length corresponding to one side of the edge of the door. , a cylindrical part 2 formed in the gasket part
Insert a string-shaped rubber magnet 3 into a and weld the cut ends to form a square frame shape, fit and fix the plate O which will become the surface of the door into the groove /c provided in the frame part l, and place it inside the refrigerator. A door bag 7 is attached to the facing back side, a heat insulating material such as urethane foam is applied between the plate O and the door bag 7, and a handle etc. are attached to complete the door.

According to the present invention, since the gasket part 1 is integrally welded to the frame part 1, which is the edge sash, the gap caused by repeatedly opening and closing the door can be completely eliminated, and the cold air insulation effect can be achieved. The refrigerator can be maintained for a long period of time in the same way as when it was new, has an energy saving effect, and eliminates the need for the process of attaching the gasket part when assembling the door, which has the effect of reducing the manufacturing cost of the refrigerator.

Furthermore, if a refrigerator is used for a long time, the gasket section at the bottom of the refrigerator may become contaminated with seasonings, broth, etc. that have leaked into the refrigerator and may break. In such a case, if you hold a knife in contact with the continuous part A of the gasket part A and the picture frame part L and cut the gasket part K from the picture frame part L with the knife, the picture frame part L will be made of hard resin. Since the gasket part A is hard and the gasket part A is made of a soft resin, the gas nut part A can be easily and accurately cut out from the continuous part A as shown in FIG.

In place of the gasket part A that has been cut out, as shown in Figure 2, it has the same cross-sectional shape as the gasket part A, and only the base lIf is extended to the extendable part B, and is continuous with the extendable part B, so that the mounting is done using a convex part. Repair gasket with part S and formed into a square frame shape) f
If the convex part S is fitted into the concave part /d of the picture frame part l and fixed, the picture frame part li will be a repair gasket (9). be able to. .

The repair gasket mounting recess /d may be groove-shaped or dot-shaped, and may be formed so that the repair gasket ()+ can be fitted therein.
