Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigerator that is provided with a condenser in the lower part of the main body and has a ventilation passage on the back surface of the main body that runs from the lower part of the main body 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. When the compressor operates, the warmed air moves up in the ventilation passage, passes through the upper part of the main unit, and draws in outside air from the lower part to cool the condenser. Because the compressor was installed in the same compartment as the container, the temperature of the air rising through the ventilation passage on the back became extremely high, and 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 condenser.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a refrigerator main 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' containing a part of a condenser 6 at the bottom of the main body. are formed, respectively, and an evaporation plate 19 is placed on the condenser 6. This evaporating dish 19 collects defrosting water. 7 is the outer box. Reference numeral 8 denotes an inner box made of resin, which integrally forms three compartments: a storage box 9 formed on the front side of the compressor compartment 3, the freezer compartment 4, and the refrigerating compartment 5. 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; and 15 is a lower door that closes the refrigerator compartment. The insulation wall 12' on the back side of the insulation box 12 includes:
A condenser 6'', which is the remainder of the condenser 6, is built-in and is attached in contact with the partition plate 10 forming the heat insulating wall 12'. A ventilation passage 16 is formed therebetween to communicate the upper compressor chamber 3 and the lower lower condenser chamber 6'. Air holes 17 are provided. 18 is a back plate that closes the ventilation passage.
The condenser chamber 6' is formed so as to have an open bottom surface and suck in external air.

In this way, the condenser 6 is provided in the lower part of the refrigerator body 1, and the ventilation passage 16 that communicates the condenser chamber 6' and the compressor chamber 3 is provided, and the condenser 6'' is placed in contact with this ventilation passage 16. The compressor 2 is built into the heat insulating wall 12' and is provided in contact with the partition plate 10 on the side of the ventilation passage 16 forming the heat insulating wall 12'. By providing the ventilation hole 17 in the box 7, the high-temperature air warmed by the compressor 2 is directly discharged from the ventilation hole 17 to the outside air, so that the air passing through the ventilation path 16 is Since the air is heat-exchanged only by the condenser 6 and the condenser 6'' on the back, 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 radiation efficiency of the condenser 6 can be improved. Furthermore, by setting the condenser 6 to the minimum size necessary for the evaporation capacity, the suction resistance of outside air is reduced, the amount of ventilation in the ventilation passage 16 is increased, and, moreover,
The heat dissipation efficiency of the condenser 6'' can be improved by providing the condenser 6'' in contact with the partition plate 10 that is in contact with the ventilation passage 16 having the highest ventilation speed. Further, since the condenser 6'' is built into the heat insulating wall 12' which is in contact with the ventilation passage 16, the condenser 6'' does not act as ventilation resistance, so that a sufficient amount of ventilation can be ensured.

As is clear from the above description, in the refrigerator of the present invention, a part of the condenser is provided at the bottom of the main body, a ventilation passage is formed on the back of the main body passing from the bottom of the main body to the top of the main body, and the residue of the condenser is used to ventilate the condenser. It is built into a heat insulating wall that is in contact with the road, is provided in contact with a partition plate of the ventilation channel that forms the heat insulating wall, and is further provided with a compressor at the top of the main body, so that the air passing through the ventilation channel is There is almost no difference between the temperature and the outside air temperature, so the heat effect on the refrigerator itself can be kept to a minimum.Furthermore, the ambient temperature around the condenser is also no different from the outside air temperature, which improves the heat dissipation efficiency of the condenser. I can let you do it. Furthermore, since the condenser is built into the heat insulating wall adjacent to the ventilation passage, the condenser does not act as ventilation resistance, so a sufficient amount of ventilation can be ensured.
