Description

[Detailed description of the invention] This invention relates to an improvement of a forced air-cooled refrigerator in which the radiator is forcibly cooled by a fan, and aims to provide a refrigerator that is more efficient and easy to use in general households. .

Conventionally, in this type of refrigerator, as shown in FIG. The fan 4 was configured to blow air in the direction shown by the arrow in the figure. However, this system was originally called the built-in type, and was designed with the assumption that the refrigerator would be buried inside the wall, but warm air that cooled the radiator, compressor, etc. Because of the discharge of water, users of the refrigerator often felt uncomfortable when they came into contact with their feet. This feeling was especially strong in ordinary homes where there were few cases where the device was actually recessed into the wall.

This idea aims to provide an efficient refrigerator while eliminating the above-mentioned drawbacks.
This will be explained in detail with reference to FIG.

Reference numeral 1 denotes a refrigerator main body, in which a main radiator 2 and a fan motor 3 for driving a fan 4 are installed on one side of a partition plate 7 in a lower machine room, and a compressor 5, an auxiliary radiator 6, and a fan motor 3 for driving a fan 4 are installed on the opposite side. An evaporation plate 11 is provided to receive and evaporate defrost water from the mounted cooler 14. Note that 8 is the air intake port, 9 is the front exhaust port, and 10 is the air intake port.
12 is a rear discharge port, 12 is a decorative cover, and 13 is a well-known capillary tube that connects the radiator 2 and the cooler 14.

When a refrigerator configured in this way is normally installed, the air sucked in from the air suction port 8 cools the main radiator 2, passes through it, and then is sent to the compressor 5 by the fan 4.
Most of the air is blown out from the rear outlet 10 where there is no resistance, and a small portion passes through the evaporating dish 11 and is discharged from the front outlet 9, so it is hardly felt at the feet of the user. It's getting old.
However, although the amount of warm air passing through the evaporating dish 11 is drastically reduced, the auxiliary radiator 6 installed at the bottom of the evaporating dish 11 can raise the water temperature in the evaporating dish to obtain the specified amount of evaporation. Water intake will not overflow. Moreover, as shown in FIG. 3, this auxiliary radiator 6 includes a compressor 5, an auxiliary radiator 6
Since the main radiator 2, the capillary tube 13, and the cooler 14 are connected in series, the temperature becomes very high, and the amount of evaporation in the evaporating dish 11 can be further increased. Therefore, the area (volume) of the evaporating dish 11 can be small, making it possible to increase the surface area of the main radiator 2, thereby increasing the efficiency of the refrigerator.

Furthermore, when used as a built-in type by being embedded in a wall, the resistance at the rear exhaust port 10 increases so that air is exhausted from the front exhaust port 9, allowing normal cooling operation.

In this way, according to this invention, warm air is discharged from the rear exhaust port in most cases of use, without causing discomfort to the user, and without damaging the evaporation of frost water or the performance of the radiator. Rather, it is possible to provide an excellent refrigerator that can improve each performance.
