Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a refrigerator, and in particular, partition walls that partition the inside of the main body into upper and lower parts are simultaneously molded integrally with the inner box.

Conventionally, in this type of refrigerator, the partition wall is formed by integrally molding the rear wall of the inner box at a suitable position to bulge forward, but when forming the partition wall by vacuum forming or the like, the partition wall is formed as shown in Fig. 7. The thickness T1 of the front side IA of the box 1, the thickness T2 of the center part of the bottom side 1B, and the thickness T3 of the back wall 2A of the inner box 2 located near the rear end of the bottom side IB are mutually such that T□>T2>T3. The thickness T of the lower side IB of the partition wall 1 gradually decreases toward the rear.

Therefore, when supporting various devices with weak strength,
It was so-called sticky and difficult to hold in a fixed position, and it also drooped and was deformed or damaged.

This proposal was developed in view of these points, and the figure will be explained below.

Reference numeral 3 denotes a refrigerator body composed of an inner box 2, an outer box 4, and a heat insulating material 5 filled between the two boxes 2 and 4. The interior is divided into two upper and lower units 6 and 7 by a partition wall 1 which is continuous and integrally formed and bulges forward near the opening.

At the back of the upper chamber 6 whose front opening is openable and closable with a door body 8, a decorative board 9 is installed in front of the back wall 6A, and a cooling chamber 11 in which an evaporator 10 of a refrigerant cycle is disposed is provided. is forming.

The cold air cooled by the evaporator 10 is accelerated by a blower 12 for forced circulation of cold air disposed above the evaporator 10,
The cold air is discharged and supplied to the upper chamber 6, which becomes the freezing chamber, from a discharge port 13 formed at a suitable place such as the upper part of the decorative panel 9, and is also supplied through a cold air flow path 15 formed by a duct plate 14 etc. attached to the back of the inner box 2. The liquid is discharged and supplied from the supply port 17 to the lower chamber 7, which serves as a refrigerating room whose front opening is openably and closably closed by the door body 16.

The duct plate 14 has a substantially U-shaped cross section, and the upper back wall 6A on the upper chamber 6 side of the inner box 2 and the lower chamber 7 close the opening of the duct plate 14.
It is attached to the lower back wall 7A by screws 18 or adhesive, and forms the cold air flow passage 15 together with the upper back wall 6A, lower back wall 7A, etc.

The upper back wall 6A has an outlet 19 communicating with the cooling chamber 11, the lower back wall 7A has the supply port 17, and the duct plate 14
It is formed at an appropriate location so as to communicate with the cold air flow passage 15 formed in .

The front opening of the portion of the duct plate 14 facing the partition wall 1 is closed with a cover plate 20 so that no leakage occurs in the cold air flow path 15 extending from the outlet 19 to the supply port 17. There is.

Between the upper and lower sides IC and IB of the partition wall 1, two upper and lower heat insulation plates 21 and 22, which are bottom-shaped and overlapped in advance, are arranged.
an inlet 23 communicating with the lower chamber 7 bored at a suitable position in the front of the
A hollow return duct 25 communicating with a return port 24 which communicates with the cooling chamber 11 bored at a suitable position in the rear of the upper IC is formed by overlapping each other or the like.

Reference numeral 26 denotes a reinforcing plate made of a steel plate or hard synthetic resin and formed into an arbitrary shape such as a substantially U-shaped cross section, which extends in the front-rear direction and abuts the center of the upper surface of the lower side 1B of the partition wall 1, and is attached to the lower chamber 7 side. The front end is extended to the vicinity of the front side IA of the partition wall 1, and the rear ends 26B, 26B of both sides 26A, 26A, etc. are supported by screws 27, 27 of the duct plate 14.
A.

It is fitted into and engaged with the engaging holes 28, 28 formed in the opposing parts of 14A.

The underside heating plate 22 has a recess 29 formed in its lower surface facing the reinforcing plate 26 into which the reinforcing plate 26 is fitted.

In the space 30 between the front side IA of the partition wall 1 and the front end of the insulation board 21.22, there is a insulation material 5 filled with foam between the boxes 2 and 4.
The front end of the reinforcing plate 26 is buried.

It is desirable that the return port 24 formed in the upper side IC of the partition wall 1 be formed in the form of a protrusion 31 that bulges slightly upward as in the embodiment, in order to reduce the intrusion of dew water.

A heat insulating plate 21.2 with a bottom shaped in advance on both the upper and lower sides IC, 1B
2, a part of the heat insulating material 5 may be foamed and filled between both the inner and outer boxes 2.4 at the same time.

In this case, the return duct 25 needs to be formed of a cylindrical body or the like.

32 is a support rail that slidably supports one side of a storage container 33 and 33 provided as necessary in the upper part of the lower chamber 7;
It is suspended from the lower side IB of the partition wall 1 using screws 34, 34, etc.

When this support rail 32 is suspended by the screws 34.34, the screws 34.34 pass through the lower side IB of the reinforcing plate 2.
6 directly or through a nut (not shown) or the like, and the screws 27 and 27 for the reinforcing plate 26 may also be used.

Although the embodiment in which the rear end 26B of the reinforcing plate 26 is fixedly supported by the duct plate 14 has been described, if the refrigerator is not a forced cold air circulation type refrigerator, the cold air flow passage 15 is not necessary.
Although the duct plate 14 is not provided, the upper and lower back walls 6A, ? A
The same effect can be obtained even if the reinforcing plate 26 is mounted between the reinforcing plates 26 and the rear end of the reinforcing plate 26 is fixedly supported by the holding member.

Therefore, the duct plate 14 becomes a type of this holding member.

Since the present invention is constructed as described above, even if an appropriate member is suspended and attached to the lower side of the compartment wall whose thickness gradually decreases toward the back, it will be reinforced with the reinforcing plate and sagging or deformation will be reduced.

Moreover, the front end of the reinforcing plate extends to the vicinity of the front side, which is relatively thick, and the rear end is engaged and supported by a holding member installed between the upper and lower back walls of both the upper and lower chambers. Only a small amount of load is applied to the rear of the center of the lower side, and the load can be supported by the front and rear ends of the strong reinforcing plate.

Further, since the rear end of the reinforcing plate is engaged and supported by the holding member, and almost no special parts are required, the structure can be simplified.

When preformed heat insulating plates are installed between the upper and lower sides of the partition wall, the reinforcing plates act as positioning guides.
