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, passing through the upper part of the main body, and draws in outside air from the lower part to cool 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.

SUMMARY OF THE INVENTION Therefore, the present invention provides a refrigerator that eliminates these drawbacks, lowers the air temperature in the ventilation duct, reduces the thermal effect on the main body, and improves the efficiency of the 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 in the upper part, a freezing chamber 4 below it, a refrigerating chamber 5 below it, and a condenser chamber 6' having a condenser 6 in its lower part. , 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.
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 an upper door that closes the storage box 9; 14 is a middle door that closes the freezer compartment 4;
15 is a lower door that closes the refrigerator compartment. 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 to communicate the upper compressor chamber 3 and the lower condenser chamber 6'.
Further, the compressor 2 is provided to protrude into the ventilation passage 16. 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 vent hole 17 in the outer box 7 facing the compressor 2, the high temperature air warmed by the compressor 2 generates an upward air current due to heat transfer and is discharged to the outside from the vent hole 17. be done. Similarly, the lower condenser 6 also generates an upward air current, which passes through the ventilation passage 16 and is discharged to the outside from the ventilation hole 17. At this time, since the air passing through the ventilation path 16 is the air that has undergone heat exchange only by the condenser 6 at the bottom, there is no difference in temperature from the outside temperature, and the thermal effect on the refrigerator body 1 can be suppressed. Moreover, since the atmospheric temperature in the lower condenser chamber 6' is no different from the outside temperature, the heat dissipation efficiency of the condenser 6 can be improved. What is more effective is that since the heat of the compressor 2 generates an upward airflow, the condenser chamber 6', which communicates with the compressor chamber 3 through the ventilation passage 16,
Since the air passes through the ventilation passage 16 and is sucked up, the wind speed increases compared to normal times. For this reason, the heat exchange efficiency of the condenser 6 can be improved. Moreover, since the compressor 2 protrudes into the ventilation passage 16, the upward airflow by the compressor sucks up the air in the ventilation passage over a short distance, improving the lifting effect and allowing the air to move upward through the ventilation passage. Since the compressor is directly cooled by air at about the outside temperature, the efficiency of the compressor can also be improved.

As is clear from the above description, the refrigerator of the present invention includes a condenser chamber housing a condenser in the lower part of the main body, a compressor chamber housing a compressor in the upper part, and a ventilation passage connecting both chambers. Since the compressor chamber is provided with a ventilation hole that communicates with the outside, and the compressor is placed in front of the ventilation path, the temperature of the air passing through the ventilation path is the same as the outside temperature, and the temperature of the air is not different from the outside temperature. It is possible to minimize the thermal effect on
Moreover, since the ambient temperature around the lower condenser is no different from the outside temperature, the heat exchange efficiency of the condenser can be improved. What is more effective is that the air in the condenser chamber passes through the ventilation passage and is sucked up by the compressor, which increases the wind speed compared to normal times. This makes it possible to further improve the heat exchange efficiency of the condenser. Moreover, since the compressor is located inside the ventilation duct, the rising airflow by the compressor sucks up the air in the ventilation duct over a short distance, improving the airflow raising effect and increasing the temperature of the outside air that has risen through the ventilation duct. Since the compressor is directly cooled by a certain amount of air, it is possible to improve the efficiency of the compressor.
