Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigerator that includes a condenser in the lower part of the main body and has an air passage extending from the lower part to the upper part of the main body.

Conventionally, this type of refrigerator has had a condenser and a compressor installed in the same compartment at the bottom of the main body, and further had an air passage on the back side extending from the bottom of the main body to the top of the main body. As the compressor operates, the air is warmed and moves up through the ventilation passages due to heat transfer, passes through the upper part of the main body, draws in outside air from the lower part, and cools the condenser. However, because the compressor is installed in the same compartment as the condenser, the temperature of the air rising through the rear ventilation passage becomes extremely high.
The thermal effect on the main body was extremely large. Moreover, the compressor raises the atmospheric temperature in the lower part, reducing the efficiency of the condenser.

Therefore, the present invention eliminates such drawbacks and
To provide a refrigerator which lowers the air temperature in a ventilation passage, reduces the thermal influence on the main body, and improves the efficiency of a lower condenser.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a refrigerator body, which has a compressor chamber 3 housing a compressor 2 at the top, a refrigerator chamber 4 below, a freezer chamber 5 below, and a condenser chamber 6' with a condenser 6 at the bottom. , an evaporation plate 19 is placed on top of the condenser 6. 7 is the outer box. 8 is an inner box made of resin, and a storage box 9 is formed on the front side of the compressor chamber 3.
Furthermore, three chambers, the refrigerating chamber 4 and the freezing chamber 5, are integrally formed. 10 is a U-shaped partition plate, and a foamed heat insulating material 11 is filled between it and the inner box 8 to form a heat insulating box 12. 13 is the storage box 9
14 is a middle door that closes the refrigerator compartment 4, and 15 is a lower door that closes the freezer compartment 5. A part of the condenser 6 is built in the heat insulating box 12 (not shown). A ventilation passage 16 is formed between the outer box 7 and the partition plate 10, and the upper The compressor chamber 3 and the lower condenser chamber 6' are communicated with each other. A ventilation hole 17 is provided in the outer box 7 at a position facing the compressor 2. 18 is a back plate that closes the ventilation path.

In this way, the condenser 6 is provided in the lower part of the refrigerator main body 1, the ventilation passage 16 is provided to communicate the condenser chamber 6' and the compressor room 3, and the compressor is provided in the upper part of the refrigerator main body 1. By providing a ventilation hole 17 in the outer box 7 facing the compressor 2, the high-temperature air warmed by the compressor 2 is directly discharged from the ventilation hole 17 to the outside air, so that the ventilation path 16 is Since the air passing through is the air that has undergone heat exchange only by the condenser 6 at the bottom, there is almost no difference from the outside temperature, and the thermal effect on the refrigerator body 1 can be kept small. Since the ambient temperature in the condenser chamber 6' is no different from the outside temperature, the heat dissipation efficiency of the condenser 6 can be improved. Furthermore, by placing the freezer compartment 5 away from the compressor 2 and positioning it at the bottom of the main body 1, and providing the refrigerator compartment at the top, the temperature difference with the compressor compartment 3 is reduced, reducing the amount of heat absorbed as a whole. It is possible to measure power saving.

As is clear from the above description, the refrigerator of the present invention is provided with a condenser in the lower part of the main body, a ventilation path passing from the lower part of the main body to the upper part of the main body, and a compressor in the upper part of the main body. Since the refrigerator compartment is located at the lower part of the refrigerator compartment, the temperature of the air passing through the ventilation passage is almost the same as the outside temperature, and the thermal effect on the refrigerator body can be kept to a minimum. Moreover, since the ambient temperature around the lower condenser is no different from the outside temperature, the heat dissipation efficiency of the condenser can be improved. Moreover, by separating the freezer compartment from the compressor and locating it at the bottom of the refrigerator compartment, the temperature difference between the freezer compartment and the compressor compartment is reduced, reducing the amount of heat absorbed as a whole, resulting in power savings. It is something that can be done.
