The size is thin (for example, a depth dimension of approximately 420
mm and a width of approximately 800 mm). In this type of refrigerator,
In the past, the condenser externally provided on the outer back of the refrigerator main body is configured to be thermally conductively disposed on the inner surface of the side plate of the outer box of the refrigerator main body, thereby reducing the depth dimension. .

Recently, there has been a demand for recycling parts and materials, and in particular, each part (compressor, condenser, etc.) constituting a refrigeration cycle is also subject to recycling. From this point, the above-described refrigerator has the following problem. That is, the refrigerator main body is formed by filling a foamed heat insulating material between the outer box and the inner box, and the condenser is also embedded in the foamed heat insulating material. When the above-mentioned condenser is taken out by dismantling, the take-out is very troublesome and there is a problem that recycling is difficult.

Therefore, the present inventor has considered that a condenser is formed in the outside of the refrigerator main body at the bottom thereof with a ventilation chamber leading from the front to the rear machine room, and the condenser is provided in the ventilation chamber. . However, in this case, when the thickness is reduced, the front and rear widths of the ventilation chamber are not so large, the size of the condenser is limited, and the capacity of the condenser is small.

0 is provided. The second condenser 20 is composed of a spiral fin condenser since the equipment room 16 has a substantially cubic shape. This spiral fin condenser has a configuration in which fins 20b are spirally attached to a refrigerant pipe 20a as shown in FIG. 9, and this is bent in a meandering manner.

Further, an air blower 21 composed of an axial fan 21a and a motor 21a is mounted on the partition plate 12, and the fan 21a is located in a vent 12a of the partition plate 12. The compressor 18, the first condenser 17, and the second condenser 20 constitute a refrigeration cycle together with a not-shown cooler and the like.

In the above configuration, when the fan 21a is driven to rotate, external air is sucked into the ventilation chamber 7 from the air inlet 9e as shown by arrows in FIGS. As shown in the figure, and flows into the equipment room 16 through the front opening 8b. This equipment room 16
After bending diagonally upward, it bends toward the vent 12a of the partition plate 12, and flows into the compressor chamber 15 through the vent 12a. Then, the air exits from the exhaust port 11a to the outside through the compressor 15. The air flowing in this way exchanges heat with the first condenser 17, the second condenser 20, and the compressor 18, respectively.

According to this embodiment, the machine room 4 is partitioned into the compressor room 15 and the equipment room 16 so as to communicate with each other, and the refrigerator body 1 has an air inlet 9e at the front and a rear at the lower part.
