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 provided 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. When 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, and draws in outside air from the lower part to cool the condenser.

However, since the compressor is located in the same compartment as the condenser, the temperature of the air rising through the rear ventilation passage becomes extremely high, and the thermal effect on the main body is 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 freezing chamber 4 below it, a refrigerator chamber 5 below it, and a condenser chamber 6' with a condenser 6 installed at the bottom. An evaporation plate 19 is placed on the condenser. 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.
The three compartments, the freezing compartment 4 and the refrigerating compartment 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 freezer compartment 4, and 15 is a lower door that closes the refrigerator compartment.

A communication pipe 15' for sending the refrigerant discharged from the compressor 2 to the condenser 6 is built in the insulation box 12. A ventilation passage 16 is formed between the outer box 7 and the partition plate 10 to communicate the upper compressor chamber 3 and the lower condenser chamber 6'. 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 body 1, the ventilation passage 16 is further provided to communicate the condenser chamber 6' and the compressor chamber 3, and the compressor 2 is provided in the upper part of the refrigerator 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 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 incorporating a connecting pipe 15' for sending the refrigerant discharged from the compressor 2 to the condenser 6 in the heat insulating box 12, it is possible to eliminate a drop in refrigerant temperature and to ensure sufficient discharge from the compressor 2. Since the evaporation capacity can be secured depending on the temperature, evaporation in the evaporating dish 19 can be promoted.

As is clear from the above description, the refrigerator of the present invention includes a condenser provided in the lower part of the main body, a ventilation passage extending from the lower part to the upper part of the main body, and a compressor provided in the upper part of the main body. An evaporating dish is placed on top of the condenser, and a pipe connecting the compressor to the condenser is passed through the insulating box of the main body, so the temperature of the air passing through the ventilation path is constant. There is no difference between the temperature and the outside temperature, so the heat effect on the refrigerator itself can be kept to a minimum.Furthermore, the ambient temperature around the lower condenser is also almost the same as the outside temperature, improving the heat dissipation efficiency of the condenser. It is something that can be done. Moreover, the connecting pipe that sends the refrigerant from the compressor to the condenser,
By housing the refrigerant in a heat insulating box, it is possible to prevent the temperature of the refrigerant from decreasing, and as a result, it is possible to ensure sufficient evaporation capacity of the evaporation dish.
