DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator in which a compressor and a condenser are separated from a machine room of a refrigerator body.

[0002]

2. Description of the Related Art Generally, in a refrigerator, when moisture from food or moisture in air flowing in when a door is opened and closed forms frost on fins of an evaporator, the flow of air between the fins is reduced. In addition to the hindrance, frosting deteriorates the conductivity of the fins, thereby lowering the efficiency of heat exchange.

[0003] For this purpose, a means for periodically performing defrosting, storing the defrosted water in an evaporating dish disposed in the machine room, and evaporating the defrosted water is employed.

[0004]

The defrosting water stored in the evaporating dish is heated by a heating source in the machine room and evaporates. One of the conditions for efficiently evaporating water is evaporating from the evaporating dish. It is necessary to discharge the generated steam smoothly from the machine room without stagnation.

[0005] In recent years, a refrigerator in which the machine room is separated from the refrigerator main body has been considered in order to increase the size and reduce noise of the refrigerator. The feature of this refrigerator is that heat from the machine room is further removed to the outside. Eliminates the need for an exhaust space to escape, and allows it to be installed exactly on the wall, making it possible even under closed installation conditions such as a built-in structure.

[0006] However, while it is preferable in terms of ease of installation and noise reduction, in the treatment of defrost water, it is difficult to secure a space for allowing steam to smoothly escape, resulting in a decrease in evaporation ability.

Accordingly, an object of the present invention is to provide a refrigerator capable of efficiently releasing steam to the outside even under a closed installation condition such as a built-in structure and improving the evaporation capacity of an evaporating dish. I have.

[0008]

In order to achieve the above object,
The present invention relates to a refrigerator in which at least a compressor and a condenser among main compressors, condensers and evaporators constituting a refrigerating apparatus are separated from a machine room of a refrigerator body, and the refrigerator is provided with an evaporator. The bottom of the main body is provided with an evaporating dish for receiving defrost water generated at the time of defrosting the evaporator, and the evaporating dish is provided with evaporating means for generating a flow of air in a predetermined direction.

[0009] As the evaporation processing means, a place where the heating density of the evaporating dish by the heating source is dense and a place where the heating density is rough are generated.

According to such a refrigerator, in a place where the heating density is high, the amount of defrost water stored in the evaporating dish, which becomes steam, is larger than in a rough place, so that a strong updraft is generated. Occurs, in the coarse places the evaporated water vapor creates a stream with the air towards the dense places. Therefore, by arranging a place where the heating density is dense on the bottom front side of the refrigerator body and a rough place on the back side, the water vapor evaporated from the evaporating dish can smoothly escape from the front side of the refrigerator body to the outside. Becomes possible.

In this case, the steam that has risen by the heating source is guided forward by a guide surface such as an inclined guide, so that the steam can smoothly escape to the outside. As a result, the evaporation capacity of the evaporating dish can be promoted even in a closed installation condition.

Further, according to the present invention, a machine room having an intake duct and an exhaust duct is installed under the floor, and a main compressor, a condenser,
In the evaporator, at least a compressor and a condenser separated from the refrigerator main body are arranged, and an evaporating dish for receiving defrost water from the evaporator provided in the refrigerator main body is set.

[0013] Thus, since the machine room is disposed under the floor, the refrigerator main body can be installed exactly on the wall, and the heat of the machine room is dissipated by the air intake duct and the exhaust duct which connect the machine room to the outside air. By flowing, it can be done smoothly.

Therefore, the defrost water of the evaporating dish derived from the evaporator is evaporated by a heating source such as a compressor, and the like.
The water vapor is smoothly discharged from the exhaust duct to the outside air outside the machine room. As a result, rapid evaporation of the steam in the evaporating dish is obtained.

The central portion is an evaporating dish installation portion 29 in which the evaporating dish 25 is arranged. Both sides of the evaporating dish installation part 29 are air passages 31, 31.
The air taken in from 1a passes behind the evaporating dish installation part 29 and is discharged from the front outlet 29a.

That is, the evaporating means 33 is provided with heaters 35, 35 managed and controlled by a control unit (not shown) to place a place having a high heating density on the bottom front half 25a of the evaporating dish 25 and a heating density on the rear half 25b. Form a rough place, and as shown by the solid line in FIG. 5, the first half 25a is set so that the air temperature immediately above the evaporating dish is higher than the second half 25b.
Thereby, in the evaporating dish 25, with respect to the latter half side 25b,
The first half 25a has a large ascending airflow, so that a flow of air flowing from the second half 25b toward the first half 25a is created. Note that the dotted line in FIG. 5 shows the temperature distribution when the front and rear portions are equalized.

The evaporating dish 25 is provided with a partition wall 37 for dividing a first half 25a and a second half 25b, which are a dense place and a rough place of the heater 35 corresponding to the heating density.

Is provided so that the defrost water flows from the second half 25b to the first half 25a where the amount of evaporation is large.

According to the refrigerator 3 configured as described above,
In the evaporating dish 25, the evaporation amount of the steam in the evaporating dish 25 is larger in the first half 25a where the heating density is dense, compared with the second half 25b where the heating density is dense, so that a strong updraft occurs. The steam in the rough place is created together with the air to flow toward the first half 25a. As a result, in the latter half side 25b of the evaporating dish, a negative pressure area is provided for taking in air from the air passage 31, and the air from the front inlet 31a is displaced by
