Description

[Detailed Description of the Invention] The present invention relates to a refrigerator comprising a plurality of insulating boxes, which can be separated as appropriate.
In particular, the present invention relates to a refrigerator in which a condenser is disposed within a back plate so as to be protected from the surroundings.

Conventionally, this type of refrigerator is as shown in FIG. 1, FIG. 2, and FIG.
Because of the structure in which the upper and lower insulating boxes 31 and 32 are in contact with each other, when the inner boxes of the upper and lower insulating boxes 31 and 32 get cold, the outer box at the joint will not receive heat from the outside no matter how much insulation there is, so a large temperature difference will occur between them, and the outside air will A dew phenomenon occurs in the surrounding areas that are touched.

Note that 33 is a cold air discharge port, 34 is a cold air return port, and 35 is a condenser.

The present invention has been improved to eliminate the above-mentioned condensation phenomenon, and aims to actively utilize the heat dissipation of the condenser and at the same time increase the internal volume relative to the installation area.

Hereinafter, the present invention will be described in detail according to an illustrated embodiment.

Fig. 4 is a longitudinal sectional view of an embodiment of the present invention, Fig. 5 is a BB sectional view and CC sectional view of Fig. 4, and Fig. 6 is a top view of the lower insulation box of the invention. 7 is a perspective view taken along the line DD in FIG. 4, and FIG. 8 is a side view of an embodiment of the present invention.

As shown in the figure, 1 is a heat insulating box for housing a refrigeration cycle unit, and this heat insulating box 1 is composed of an outer box 2, a heat insulating material 3, an inner box 4, and a door 5 that can be opened forward.

The outer box 2 is composed of a side plate 2A, a back plate 2B, and a top plate 2C.

Reference numeral 6 designates another heat insulating box connected to the heat insulating box 1, and is arranged at an upper stage.

This insulating box body 6 is composed of an outer box 7, a heat insulating material 8, an inner box 9, and a door 10 that can be opened forward.

The outer box 7 is composed of a side plate 7A, a back plate 6B, and a bottom plate 6C.

A space 11 is formed between the bottom plate 6C and the top plate 2C of the heat insulating box 1, and a fastening device 12 and a cold air connection duct 13 are provided at appropriate positions in the space 11. .

The bottom plate 6C is attached to the side plate 7A of the heat insulating box 6.
It is fixed as shown in the figure.

The side surfaces of the space 11 are shielded by side plates 6A, but the front and rear surfaces are provided with air inlets and outlets 14 and 15, which are either integrally provided with the bottom plate 6C or formed separately.

On the other hand, a fastening device 12 and a cold air connection duct 13 are attached to the upper plate 2C, and the back plate 2B
A through hole 17 is bored so as to be located above a condenser 16 disposed in the condenser 16 .

This air inlet/outlet 17 is arranged so as to communicate with the space 11.

As shown in FIG.
6 is installed internally.

Since the condenser 16 is installed inside the back plate 2B,
The refrigerator can be installed along the wall edge 1 so as to be in contact with the back surface 1B.

At this time, the heat radiated from the condenser 16 becomes an upward airflow and enters the space 11 through the through hole 17, warming the upper plate 2C and the bottom plate 6C of the upper and lower insulation boxes 1 and 6, and serves as a heat source to prevent dew formation. At the same time, heat exchange is performed by connecting with the outside air through the through hole 17.

By aligning the dimensions of the rear surface of the heat insulating box 1 with the rear surface 18, a side surface appearance as shown in FIG. 8 is obtained.

As described above, in the refrigerator of the present invention, an insulating box having a refrigeration cycle is disposed at the lowest stage, and on top of this insulating box, insulating boxes only are successively connected. A back plate with a C-shaped cross section is provided to protect the condenser from the surroundings, and a through hole is formed in the upper part of this back plate, and the upper surface of the lowermost insulating box and the By connecting spaces with air inlets and outlets on the front and rear surfaces between the insulating boxes, the heat radiated from the condenser becomes an upward airflow and enters the space through the ventilation holes and passes through the upper and lower panels of the upper and lower insulating boxes. It warms the bottom plate and serves as a heat source to prevent condensation, and at the same time communicates with the outside air through the air outlet and exchanges heat.

In addition, the side appearance is excellent as the condenser is hidden, and the back of the refrigerator can be attached to the wall at 1, making it a valuable item as the internal volume can be increased by the amount of the condenser installed compared to the same installation floor area. Become.
