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. A gasket was inserted into the groove. 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.

Hereinafter, the present invention will be explained 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 6 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. The gasket 6 also includes a bag-like part 9 containing a magnet d, a cushion part 10 provided continuously with the bag-like part 9, and a cooker part 1o.
A contact portion 1 connected to the other end and abutting around the groove 60 of the inner plate 3
1, a mounting base 12 extending from the abutment part 11 and having a wide semi-trapezoidal tip, a protrusion 13 formed on the vertical surface of the mounting base 12, and abutting the flange 8 of the outer panel 2 on the outside. It is formed by a contact strip 7114.

In such a door 1, the gasket 6 is attached to the inner panel 3, and then the flange 8 of the outer panel 2 is manufactured.
and the ribs 7 of the inner plate 3 are brought into contact with each other and the outer plate 2. The inner panel 3 is pressed and filled with foam insulation material, and the outer panel 2. Since the inner plate 3 is fixed by the adhesive properties of the heat insulating material 4, there is no need for mounting screws, and since the groove 6 is compressed by the foaming pressure, there is no possibility that the mounting base 12 of the gasket 5 completely fitted into the groove 6 will come off. It is something. Furthermore, the ribs 7 of the inner plate 3 serve to prevent the grooves 6 from shifting when forming the grooves 6, 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. Also, a protrusion 13 formed on the vertical part of the mounting base 12
Since it is inclined upward, it serves to prevent the gasket 6 from slipping out before and after foaming.

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 semi-trapezoidal groove with a wider inner part is formed on the outer periphery of the inner plate, a gasket having a mounting base with a tapering shape is provided in the groove, and the groove is 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. This poetic feeling is due to the fact that the inner part is wide, so the opening of the groove is likely to get caught when receiving foaming pressure, and the clamping force due to foaming pressure is large, and the tip of the gasket mounting base is widened. Because of this, once it is inserted into the groove of the inner plate, it cannot be pulled out.
