Description

[Detailed Description of the Invention] The present invention relates to a refrigerator which further includes an auxiliary door in addition to the door provided at the front opening of the refrigerator main body.

Generally, every time you open the refrigerator door, cold air leaks out and warm air enters the refrigerator, which has disadvantages such as adversely affecting stored items and increasing the operating rate of the compressor, increasing the amount of electricity used. be.

Therefore, it is known to provide an auxiliary door in addition to the main door so that only necessary items can be taken out.

However, since a portion of the main door is open, the strength against twisting of the main door is not necessarily sufficient.

The present invention relates to the improvement of a refrigerator having such an auxiliary door, and in particular improves the strength of the main door by improving the reinforcing frame forming the outlet. explain.

In the figure, 1 indicates the refrigerator main body, and the front opening of the main body 1 has an upper hinge 2. Middle hinge 3. Freezer compartment door 5 by lower hinge 4. A refrigerator compartment main door 6 (hereinafter referred to as the main door) is attached so as to be openable and closable.

This main door 6 has an outer panel 7. Inner plate 89 Insulating material 9 between both plates 7 and 8
Even more impressively, bulges 10 are integrally formed on both sides of the inner plate 8 to support a shelf, etc., which will be described later.

Reference numeral 11 denotes an outlet defined by a decorative frame 12 that connects both plates 7 and 8 to approximately the lower half of the main door 6, and has an opening width approximately equal to the width between the left and right bulges 10.

This outlet 11 is equipped with an auxiliary door 14 whose lower end is pivoted by a pivot pin 13 and whose upper end opens and closes.Like the main door 6, this auxiliary door 14 also has an outer panel 15, an inner panel 16, and a heat insulating material. It consists of 17 parts.

Reference numeral 18 denotes a gasket provided on the periphery of the back surface of the auxiliary door 14, which contacts the stepped portion 12a formed on the decorative frame 12 to seal it.

Reference numeral 19 denotes a storage shelf in which wire rods are combined, which is located at the lower part of the outlet 11 opposite to the outlet 11, and is rotatably supported by bins 20 on the left and right bulges 10.

Next, the above-mentioned outlet 11 portion will be explained in more detail.

The decorative frame 12 includes a flange 12b that covers the opening edge of the outer panel 7;
It has a groove 12c formed to connect and accommodate the opening edge of the inner plate 8, and is fixed by a reinforcing frame 21.

This reinforcing frame 21 is fitted into a boss portion 12d protruding from the back surface of the stepped portion 12a of the decorative frame 12, and is fitted with a cup washer 22. Screw 23
Flanges 21a on four sides are fixed at
It has side flanges 21b.

Moreover, the latter flange 21b has both flanges 21a and 21b.
Right-angled connecting pieces 24, 24, .
... is welded.

Further, among these connecting pieces 24, 24..., connecting piece 2 on the upper side and on the opposite side of the hinge with respect to the main door 6
4' is an extending portion 2 extending upward along the back surface of the outer panel 7.
4″ is formed.

In other words, due to the presence of the outlet 11, the main door 6 is structurally divided into the outlet 11 and the upper part above the outlet 11, which has a weak strength, but it is connected to the flange 21b of the reinforcing frame 21. The piece 24' horizontally spans the two divided portions, so that the strength of the main door 6 can be maintained.

As is clear from the above explanation, in the refrigerator of the present invention, the connecting piece of the reinforcing frame at the main door outlet extends upward or downward along the back of the outer panel of the main door, so that twisting of the main door can be avoided. This has the effect of preventing this and ensuring sufficient strength, and since the connecting piece is attached to the outer panel at the same time as the reinforcing frame is attached, assembly work is facilitated.
