Description

[Detailed Description of the Invention] The present invention relates to a refrigerator door, and particularly relates to an improvement in the attachment structure of the inner door panel to the outer door panel.

Figure 1 shows the appearance of a typical one-door refrigerator. In Figure 1, 1 is the refrigerator body, and 2 is the door attached to the front of the refrigerator body 1. 2 had a structure as shown in Figure 2. That is, in FIG. 2, 1 is the refrigerator body, 2 is the door, 3 is the gasket, 4 and 5 are the door outer plate and door inner plate that constitute the door 2, and 6
and 7 are heat insulating materials. Conventionally, the gasket 3 was fitted into the extruded door outer panel 4, but the door inner panel 5 was fitted with screws 8 to the door outer panel 4.
It was fixed by

Therefore, the cost was increased by the amount of the screws 8, and additional screw fixing work was required.

Furthermore, conventionally, it has been proposed to omit the screws 8 by providing a groove that opens laterally on the outer peripheral edge of the inner door plate and fitting the outer door plate into this groove (in practice). (Refer to Publication No. 52-2646), in such a case, it is necessary to deform the inner door plate inward and then insert the edge of the outer door plate into the groove on the outer periphery. It was very difficult to perform the engagement all around the circumference.

The present invention aims to improve the conventional structure described above, and proposes a refrigerator door structure in which the inner door plate is attached to the outer door plate without using screws.

The refrigerator door according to the present invention will be explained below with reference to FIG. 3 showing an embodiment of the present invention.

FIG. 3 is an enlarged sectional view of the main parts of the refrigerator door according to the present invention, in which 10 is the refrigerator body, 11 is the door, 12 is the gasket, 13 is the outer panel of the door, 14 is the inner panel of the door, 1
5 and 16 indicate heat insulating materials.

In the present invention, as shown in FIG. 3, the peripheral edge 14a of the door inner plate 14 is formed into a U-shaped cross section, and a fitting groove 13a is formed on the door outer plate 13 side by extrusion molding. U of the door inner plate 14
The peripheral edge portion 14a of the letter shape is fitted and fixed using its elastic force.

In addition, in FIG. 3, reference numeral 13b denotes a locking protrusion to which the tip of the U-shaped peripheral edge 14a of the door inner plate 14 locks;
C is a fitting portion into which the fitting protrusion 12a of the gasket 12 fits.

As described above, according to the present invention, in the case where the door inner plate is attached to the inner surface of the door, on the side of the door where the door inner plate is attached,
A fitting groove that opens toward the installation direction of the door inner plate is formed, and a protrusion that engages with this fitting groove is provided at a position corresponding to this fitting groove on the door inner plate. When attaching the plate to the door, the protrusion of the door inner plate is pressed against the mounting surface of the door inner plate so that it engages with the fitting groove of the door, and the engagement direction matches, so the installation work is easy. It becomes extremely easy.

Moreover, since the protrusion is formed into a groove shape that is open in the same direction as the fitting groove, when inserting the protrusion, it is easy to press from the installation direction, and the engagement groove provided at the upper part of the outer periphery of the fitting groove can be easily pressed. It is easy to engage the open end of the protrusion that stands up on the mating protrusion.

Moreover, the open end of the rising protrusion comes into pressure contact with the engagement protrusion, preventing the protrusion from coming off the engagement groove, so even if the protrusion and the door inner plate are thin, the engagement force is strong and easy. It never comes off.
