Abstract

PURPOSE:To decrease the thickness of the intermediate partition wall by making a packing attaching groove of a second frame in a form nearer to an end face part of a door than those of packing attaching grooves of other three sides so that a magnetized part of a packing is located more nearly to the end face part than those of other three sides when attached in a packing attaching frame of the door. CONSTITUTION:A packing attaching frame 5 is formed by conbining attaching frames 5A and 5B of modified form in section as shown in Figs. 3, 4 and 5. As apparent from the figures, a side of the frame located in an intermediate partition wall 33 is different from the other three sides of the frame. When attaching legs of packings are secured in attaching grooves of the frame, the magnetized part 23a of the packing 23 is located on the side of an end face of a door. The intermediate partition wall is smaller by the dimension of W3 than a conventional one (Fig. 8). The reason is that the attaching frame facing the intermediate partition wall has a packing attaching groove is nearer by the dimension of L1 to the end face of the door than those of other three sides of the frame.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a double door refrigerator having an intermediate partition, in which the internal space is effectively utilized by making the intermediate partition as thin as possible. be.

[Conventional technology]

Generally, doors are designed with the following points in mind:

This will be explained with reference to FIGS. 2 and 6 to 11.

■Magnetized part 2 of the gasket 23 that seals between the door 22 and the main body 21
3a, as shown in FIG.
It is necessary to prevent the magnetized part 23a from twisting when opening and closing the door by placing it in a position that is not on the inner side of the refrigerator than the perpendicular line P drawn toward the pin 24a of No. 4 (the side without diagonal lines).

■For cost reasons, the above-mentioned gaskets 23 are extruded and have the same cross-sectional shape, and the end faces are cut at 45 degrees, and the four cut gaskets 23 are thermally welded at the cut portions to form a frame shape as shown in Fig. 6. It will be advantageous.

■The mounting frame 25 (Fig. 9) to which the above-mentioned packing 23 is attached is extruded into a band shape with <90 mm as shown in Fig. 11.
It is advantageous in terms of cost and manufacturing to cut the cutout portion 25a at the same time, remove the cutout portion 25a, and bend the cutout portion 25a to form a frame shape.

Figures 2 and 8 show doors designed with the above 0 to 0 points in mind.
To explain using a figure, 21 is a refrigerator body, and this refrigerator body 21 has a front opening divided into a first door 22' and a second door 22.
24 is the door 22', 22''.
This is a hinge that is pivotally attached to the main body 21. The doors 22', 22'' are comprised of the following components.

That is, the door outer panel 26, 27, the frame 28, 29, the heat insulating material 30.
31, a door inner plate 32, a gasket 23, etc. 33 is an intermediate partition that forms the magnetized portion 23a of the door 22', 22''.As is clear from the above explanation and the drawings, the magnetized portion 23a of the gasket 23 on the hinge 24 side is located closer to the main body 21 side. It is located on the inner side of the refrigerator from a perpendicular line drawn toward the hinge pin 24a.The position of the magnetized portion 23a to the front edge of the main body (the distance from the door end face to the magnetized portion) is determined on all four sides. From this, the width W1 of the above intermediate partition
The dimensions were determined. A conventional method of reducing the W1 dimension and increasing the internal volume of the refrigerator as much as possible is to use a packing having an irregular cross section as the intermediate partition. As shown in Fig. 10, this method has a structure in which the packing 23 located on the intermediate partition 33 side and the packing 23 located on the other three sides are extruded and molded using separate molds, and then heat-welded. . Although the method is different, an example of making the partition wall thinner is Japanese Patent Application Laid-Open No. 61-213582.

[Problem to be solved by the invention]

The conventional door structure described above had the following problems: 1. There is a method shown in Figure 10 above for welding the packing with an irregular cross-sectional shape, but this welding is difficult and requires various tools. There was also the problem of high costs because it required

2. Normally, the packing 23 is attached to the frame using the packing 23.
The mounting leg 23b was pushed into the groove 25a of the frame 25 as shown by the arrow. However, unlike the conventional method, there is a problem in that it is very difficult to attach the gasket 23 to the attachment frame 25.

The present invention has been made to significantly improve the above problems.

[Means to solve the problem]

In order to improve the above object, the present invention provides a method for attaching a door seal by using a first frame formed by bending a band-shaped frame into a U-shape, and a second frame located in the partition and having a cross-sectional shape different from the first frame. When the frame-shaped gasket, which has the same cross-sectional shape and is welded at four locations, is assembled to the door gasket mounting frame, the magnetized part of the gasket is closer to the door end face than the magnetized parts on the other three sides. Connect the gasket mounting groove of the second frame to the other three so that it is located nearby.
It is shaped to be closer to the door end face than the gasket mounting groove on the side.

[Effect]

The present invention makes it possible to bring the gaskets of both doors closer to each other by changing the shape of the frame on one side of the partition and the frames on the other three sides. It is possible to reduce the thickness dimension.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1, 2 to 5. Fig. 1 is a cross-sectional view taken along line A-A in Fig. 2, and Fig. 2 is a perspective view of a double-door refrigerator (this figure is also cited in the conventional example). Fig. 3 is explained in Fig. 2. Fig. 4 is a sectional view showing details of an embodiment of the seal and the seal mounting frame provided on the door facing the intermediate partition wall, and Fig. 5 is a front view of the seal mounting frame installed on the wall other than the intermediate partition wall. FIG. 3 is a cross-sectional view showing details of an embodiment of the packing and packing mounting frame provided on three sides of the door to face each other.

First of all, referring to Fig. 2, 21 is the refrigerator body, 2
Reference numeral 2 designates a door body that closes a front opening inside the refrigerator body formed inside the refrigerator body 21 from both sides, and 24 designates a hinge.

Next, referring to FIG. 1, the door main body 22 includes a door outer panel 1, a heat insulating material 2. It is composed of a door inner plate 3, a packing 4, a packing mounting frame 5, and the like. 6 is an intermediate partition wall.

As can be seen from Figures 1, 4, and 5, the above-mentioned packing 4
The left and right sides have the same cross-sectional shape, and the gasket 4 used in the embodiment has the same cross-sectional shape on four sides. Also.

The cross-sectional shape of the part of the packing mounting frame 5 facing the intermediate partition wall 6 is as shown in FIG. 5, and has a different cross-sectional shape from the mounting frames provided on the other three sides shown in FIG. ing. That is, this gasket mounting frame 5 is made by combining a mounting frame 5A and a mounting frame 5B having irregular cross-sectional shapes as shown in FIGS. 3, 4, and 5.

As is clear from the figure, one side of the frame located on the intermediate partition wall 6 is different from the other three sides of the frame, and when the mounting leg 4b of the packing is assembled into the main mounting groove 5a, the mounting of the packing 4 is difficult. The magnetic part 4a is formed in such a way that it is located on the door end face side (of course, the other three sides are located in such a way that the seal 4 is not twisted in relation to the hinge pin 24a explained in the conventional example, that is, in a comparative example). (It is attached to the gasket attachment groove 5a so that it is in the position inside the target storage.) By configuring as described above, the grooves of the seal mounting frame 5 are misaligned at the joint portion of the mounting frame 5A and the mounting frame 5B, as shown in FIG. In order to attach the gasket to this shifted groove, in this embodiment, the mounting leg 4b of the gasket (the shaded area in FIG. 6 cited in the conventional example) is partially canned to accommodate this. It is something.

Next, the intermediate partition wall of the refrigerator to which the door having the above structure is attached is smaller by the W3 dimension compared to the conventional refrigerator (FIG. 8). This is because the mounting frame facing the intermediate partition wall has a groove for attaching the gasket L compared to the frames on the other three sides.
This is due to the fact that it is offset by one dimension toward the end face of the door. As a result, the refrigerator of this embodiment can effectively utilize the internal volume by W3 (W1-W2-=W3) compared to the conventional refrigerator.

〔Effect of the invention〕

Since the present invention uses gasket mounting frames of different shapes and combines these different shapes of mounting frames, it is possible to obtain a door that is inexpensive and has good workability. Also,
Since the shape of the gasket (particularly the mounting leg) can be left as it is, insertion of the gasket into the gasket mounting frame can be mechanized as in the past, and installation can be easily performed.
