Description

[Detailed description of the invention] This invention uses the heat exhaust device of the cooling system to
This invention relates to a refrigerator that also exhausts the heat of evaporated water from the cooler, improving usability and efficiently exhausting the heat of evaporated water.

Generally, in a refrigerator whose back is installed close to the indoor wall, condensed heat from the cooling system, heat radiated from the compressor, etc. are exhausted from the front of the upper end of the refrigerator body using a fan. Therefore, when a user stands in front of the refrigerator body, the user feels the exhaust heat near the head, which causes discomfort, especially in the summer when the outside temperature is high.

On the other hand, the defrost water from the cooler of the cooling system was heated and evaporated at the bottom of the refrigerator using heat of condensation. However, the heat of the evaporated water accumulated in the vicinity, which was undesirable.

The present invention eliminates the drawbacks of the conventional example described above.
An embodiment will be described below with reference to the drawings.

Reference numeral 1 denotes a refrigerator body in which a freezer compartment 3 and a refrigerating compartment 4 are formed above and below through a partition wall 2, and each of the compartments has doors 5 and 6.
has. 7 is a machine room installed on the top surface of the refrigerator body 1 and having a large number of exhaust holes 8 in the back of the top surface;
The cooling system includes a compressor 9, a condenser 10, and a fan 11 for cooling them. 1
A duct 2 has one end formed integrally with the intake side of the fan 11 in the machine room 7 to communicate with it, and has a large number of intake holes 13 in the other end. It is formed by making a recess and closing it with a back plate 14. 15 is a cooler installed at the back of the freezer compartment 3, and 16 is a conduit for draining the defrosting water from the cooler 15 to the evaporator A in the duct 12.
The evaporator A includes a drainage receiver 7 and an electric heater 1.
Consists of 8. Reference numeral 19 denotes a spacer provided at the upper and lower ends of the back surface of the refrigerator body to maintain a slight gap 21 between it and the wall surface 20.

In the above embodiment, during the cooling operation, heat is radiated from the compressor 9 and the condenser 10, but the heat is sucked in by the rotating fan 11 and exhausted from the exhaust hole 8 to the upper rear side of the refrigerator body 1. On the other hand, the rotation of the fan 11 also draws wind into the duct 12. That is, air sucked through the intake hole 13 rises in the duct, passes through the machine room 7, and is discharged from the exhaust hole 8. Therefore, cooler 1
Defrost water from 5 is drained by conduit 16 and evaporated in evaporator A, its heat being discharged along with the previous air flow (arrows in FIG. 1).

In this way, the present invention allows the heat dissipated from the cooling system to be exhausted from the exhaust hole at the back of the top of the refrigerator body, so the user who stands in front of the refrigerator body can comfortably use the refrigerator in both summer and winter without being exposed to exhaust air. It is a simple structure that can be used to exhaust the heat of the device that evaporates waste water from the cooler using a fan that cools the compressor and condenser of the cooling system through the duct, and can be done efficiently.
