Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a refrigerator cabinet, and particularly to an assembly structure of an inner box body constituting the cabinet.

[Conventional technology]

5 to 7 show conventional examples of this type of device. In the figures, 1 is an inner box consisting of a freezer compartment box 2, a refrigerator compartment box 3, and a heat insulating member 4 inserted between the two. A main body, 5 is an outer box that surrounds the outer periphery of the inner box main body 1 with a predetermined interval, and 6 is a heat insulating material made of foamed resin that is filled in the space formed between the inner box main body 1 and the outer box 5. , 7 is the opening 2 of the freezer compartment box 2
7a is a flange formed on the outer periphery of the flange 7, 8 is a flange formed on the outer periphery of the opening 3a of the refrigerator compartment box 3, 8a is the flange 8
The upper side 9 is the lower side 7a of the flange 7 of the freezer indoor box 2 and the upper side 8a of the flange 8 of the refrigerator indoor box 3.
A connecting plate 10 connects the connecting plate 9 and the lower side 7a of the flange 7 and the upper side 8a of the flange 8.
A connector 11 is an adhesive tape that fixes the heat insulating member 4 inserted between the freezer compartment box 2 and the refrigerator compartment box 3.

[Problem that the invention attempts to solve]

Since the conventional inner box main body 1 is configured as described above, a connecting plate 9 and a connecting tool 10 are required to connect the freezer compartment box 2 and the refrigerator compartment box 3, which increases the number of parts and reduces assembly man-hours. At the same time, the drain generated during defrosting flows down from the opening 2a of the freezer compartment box 2, and the drain is generated between the flange bottom side 7a of the freezer compartment box 2 and the flange top side 8a of the refrigerator compartment box 3. penetrates into the insulation member 6 through the gap,
There were problems such as a decrease in insulation performance.

This idea was devised to solve the above-mentioned problems, and it not only reduces the cost by reducing the number of parts and assembly man-hours, but also reduces the amount of condensate generated during defrosting inside the freezer compartment box. It is an object of the present invention to provide a refrigerator cabinet which is inexpensive and has stable performance without fear of intrusion into a heat insulating member in the lower part of a freezer compartment box.

[Means to solve the problem]

The refrigerator cabinet according to this invention has a flange formed on the rear side of the lower side of the flange formed on the outer periphery of the front opening of the upper freezer compartment box, and a flange formed on the outer periphery of the front opening of the lower refrigerator compartment box. The upper sides of the flanges are overlapped and connected by a connecting member.

[Effect]

In this invention, the number of parts is reduced, the number of assembly steps is also reduced, and condensate generated during defrosting does not enter the heat insulating member.

〔Example〕

An embodiment of this invention will be described below with reference to FIGS. 1 to 3. In the figure, the same reference numerals as in FIGS. 5 to 7 indicate the same or equivalent parts, 7b is a through hole formed on the flange lower side 7a of the freezer compartment box 2 and through which the connector 10 passes, and 8b is the through hole of the refrigerator compartment box 3. is formed on the upper part of the flange 8 on the outer periphery of the opening 3a,
An upper side portion 8d whose vertical dimension is approximately twice the width dimension of the side portion 8c is formed on the upper side portion 8b, and is connected to the coupling tool 1.
0 is a through hole.

Next, the freezer compartment box 2 is constructed as described above.
The refrigerator compartment box 3 is attached to the rear side of the lower side 7a of the flange 7.
The upper sides 8b of the flanges 8 are overlapped, and the fittings 10, such as rivets, are passed through the through holes 7b and 8d formed in the lower side 7a and the upper side 8b of the flanges 7 and 8, and the tips of the flanges 8 and 8 are caulked. A refrigerator indoor box 3 is connected to the lower part of the indoor box 2, and a heat insulating member 4 is inserted between the freezer indoor box 2 and the refrigerator indoor box 3, and fixed with adhesive tape 11 as shown in FIG. Assembly of main body 1 is completed.

As described above, the flange lower side 7a of the upper freezer compartment box 2 is placed on the front side, and the flange upper side 8a of the lower refrigerator compartment box 3 is placed on the rear side, so that the opening of the freezer compartment box 2 Drain flowing down from 2a does not enter into the heat insulating material 6 from these joints.

Figure 4 shows another embodiment of this invention.
In the figure, the same reference numerals as in FIGS. 1 to 3 indicate the same or equivalent parts. 8e is the upper side of the flange 8 of the refrigerator compartment box 3, and the upper side 8e is the side part 8c of the flange 8 that is The flange 7 is formed to be set back by the wall thickness d, and the front surfaces of the flange 7 of the freezer compartment box 2 and the flange 8 of the refrigerator compartment box 3 are arranged on the same plane, and the effect is the same as that of the above embodiment. It is exactly the same as that of .

[Effect of idea]

Since this invention is configured as described above, the number of parts is reduced, which reduces assembly man-hours, lowering costs, and drains generated during defrosting inside the freezer compartment box are drained into the insulation material at the bottom of the freezer compartment box. This has the effect of providing a refrigerator cabinet that is inexpensive and has stable performance without fear of intrusion into the refrigerator.
