Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching a door gasket to a refrigerator or the like.

In conventional refrigerator door gasket installation, the outer and inner panels are connected with a sash, filled with foam insulation material, and a groove for inserting the gasket is formed in the sash. It was to insert a gasket.

However, in such a mounting structure, since the gasket is simply fitted, there is a risk that the gasket may come off during the door opening/closing operation.

Furthermore, the groove was deformed by the foaming pressure, making it difficult to insert the gasket.

An object of the present invention is to provide a method for attaching a door gasket to a refrigerator, etc., which improves the above-mentioned difficulties.

The present invention will be explained below with reference to the drawings showing one embodiment thereof.

Reference numeral 1 denotes a door provided at the front of the refrigerator, which includes an outer panel 2 formed in a box shape, an inner panel 3 forming a space between the outer panel 2, and
It is formed of a heat insulating material 4 filled between the outer plate 2 and the inner plate 3, and a gasket 5 provided on the inner plate 3.

The inner plate 3 is an elastic synthetic resin plate, and has a semi-trapezoidal groove 6 with a wider end formed on its outer periphery, and a rib 7 extending in the same direction on its outer periphery.

This rib 7 serves as a holding part for a mold (not shown) when forming the groove 6 by vacuuming, and also comes into contact with a flange 8 extending inward from the box-shaped part of the outer panel 2. ing.

Further, the gasket 5 includes a bag-like portion 9 containing a magnet 91, a cushion portion 10 provided continuously with the bag-like portion 9, and a cushion portion 10 connected to the other end of the cushion portion 10 and in contact with the periphery of the groove 6 of the inner plate 3. The abutting part 11 that contacts, the mounting base 12 that extends from the abutting part 11 and has a wide semi-trapezoidal tip, the protrusion 13 formed on the vertical surface of the mounting base 12, and the outer plate 2 on the outside. It is formed by a flange 8 and a fin 14 that comes into contact with it.

In such a door 1, the gasket 5 is attached to the inner panel 3, and then the flange 8 of the outer panel 2 is manufactured.
The ribs 7 of the inner plate 3 are pressed against the outer plate 2 and the inner plate 3 to fill the foam insulation material. No mounting screws are required, and since the groove 6 is compressed by the foaming pressure, the mounting base 12 of the gasket 5 fitted into the groove 6 will not come off.

Furthermore, the ribs 7 of the inner plate 3 serve to prevent displacement when the grooves 6 are formed, and when the heat insulating material 4 is foamed, they improve contact with the flange 8 of the outer plate 2 to prevent leakage of the heat insulating material 4. At the same time, the fins 14 form a heat insulating space on the outside of the gasket 5 and serve as a cover plate.

In addition, since the protrusion 13 formed on the vertical part of the mounting base 12 is inclined upward, the gasket 5 before and after foaming
This serves as a stopper to prevent it from coming off.

As is clear from the above embodiments, the method for attaching a gasket to a refrigerator, etc. of the present invention is to install a door using an outer panel, an elastic inner panel made of synthetic resin, etc., and a heat insulating material filled between the outer panel and the inner panel. a half-joint-shaped groove with a wider inner part formed on the outer periphery of the inner plate, a gasket having a mounting base with a tapering shape provided in the groove, and formed by the inner plate and the outer plate. The space is filled with a foaming heat insulating material, and the foaming pressure of this heat insulating material compresses the groove and fixes the mounting base of the gasket within the groove. During use, the gasket is held in the groove by the foaming pressure. Since the opening of the groove is wide at the back, there is a risk that the opening of the groove will be pinched when the foaming pressure is applied. The tip of the base is widened, so once it is inserted into the groove of the inner plate, it is difficult to come out.
