Description

[Detailed Description of the Invention] The present invention relates to a refrigerator that has a condenser in the lower part of the main body and has an air passage on the back side 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 in the lower part of the main body, and has an air passage on the back side extending from the lower part to the upper part of the main body.

Then, when the compressor was operated, the warmed air rose through the ventilation duct due to heat transfer, passed through the upper part of the main body, and at the same time sucked in outside air from the lower part of the main body to cool the condenser.

However, because the condenser and compressor are located in the same compartment, the temperature of the air rising through the rear ventilation path is extremely high, and the heat effect on the refrigerator body is large.

Moreover, since the ambient temperature at the bottom of the main body is increased by the compressor, the heat dissipation efficiency of the condenser is reduced.

Therefore, the present invention provides a refrigerator that eliminates these drawbacks, lowers the temperature of the air rising through the ventilation duct, reduces the thermal effect on the main body, and improves the heat dissipation efficiency of the condenser. It is something to do.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a refrigerator main body, with a compressor chamber 3 having a compressor 2 installed at the top of the main body, a storage chamber 4 in front of the compressor chamber 3, and a freezing chamber 5 below it.
, a refrigerating chamber 6 below it, and a condenser chamber 8 in which a part of a condenser 7 is provided at the bottom of the main body.

An evaporating dish 9 is placed on a part of the condenser 7.

This evaporating dish 9 collects defrosting water and evaporates this defrosting water.

10 is an outer box.

Reference numeral 11 denotes an inner box made of synthetic resin, which includes the storage chamber 4, the freezing chamber 5,
The door chamber of the refrigerator compartment 6 is integrally formed.

12 is a U-shaped partition plate, and a foamed heat insulating material 13 is filled between it and the inner box 11 to form a heat insulating box 14.

15 is an upper door that closes the storage chamber 4; 16 is a middle door that closes the freezer compartment 5; and 17 is a lower door that closes the refrigerator compartment 6.

A ventilation passage 18 is formed on the back surface of the refrigerator main body 1 to allow the compressor chamber 3 and the condenser chamber 8 to communicate with each other.

The condenser chamber 8 has an open bottom surface and is formed to suck in outside air.

A ventilation hole 19 is provided in the outer box 10 at a position facing the upper surface of the compressor 2.

The ventilation passage 18 is formed by the outer box 10 and a back plate 20 provided so as to close the ventilation passage 18.

Furthermore, bent portions are provided on the left and right sides forming the ventilation passage 18 and on the top side of the outer box 10 so as to form a U-shaped groove 21 that faces the outside air and the ventilation passage 18. A part of the condenser 7 is housed in the groove 21.

In this way, the condenser chamber 8 in which a part of the condenser 7 is installed is provided in the lower part of the refrigerator main body 1, and the compressor chamber 3 in which a compressor is installed in the upper part of the main body, and the condenser chamber 8 and the compressor A ventilation passage 18 communicating with the chamber 3 is formed on the back of the main body, and U-shaped bag portions 21 are formed on the left and right sides and the top side of the outer box 10 forming this ventilation passage 18. A portion of the remaining condenser 7 is built in.

Therefore, the air warmed by the compressor 2 rises due to heat transfer and is directly discharged to the outside from the ventilation hole 19, so that the air rising through the ventilation passage 18 is limited to only a portion of the lower condenser 7. Since it is heat-exchanged air, there is almost no difference from the outside temperature, and the thermal influence on the refrigerator body 1 can be minimized.Moreover, the atmospheric temperature in the condenser chamber 8 is also
Since there is no difference from the outside temperature, the heat dissipation efficiency of a part of the condenser 7 can be improved.

Also, the remaining part of the condenser 7 is built in the U-shaped groove 21 of the outer box 10 facing the outside air and the ventilation path 18.
Since heat is radiated to both the outside air and the air rising through the ventilation path 18, it is possible to improve heat radiation efficiency.

As is clear from the above explanation, the refrigerator of the present invention is
A part of the condenser is provided in the lower part of the main body, a ventilation passage is provided in the back of the main body that runs from the condenser chamber where the part of the condenser is provided in the lower part of the main body to the upper part of the main body, and a compressor is provided in the compressor room in the upper part of the main body. At the same time, a U-shaped groove is formed in the outer box that communicates with the ventilation passage and forms the ventilation passage so as to face the outside air and the ventilation passage, and the remaining condenser is placed in this groove. Since the temperature of the air rising in the ventilation duct is almost the same as the outside temperature, the heat effect on the refrigerator body can be kept to a minimum. Since the ambient temperature around a part of the condenser is no different from the outside temperature, the heat dissipation efficiency of the part of the condenser can be improved.

In addition, since the condenser is built into a U-shaped groove that faces the outside air and the ventilation path, heat is radiated to both the outside air and the air inside the ventilation path, improving heat radiation efficiency. It is.
