DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an evaporator for a refrigerating box equipped with an evaporator that sucks up and evaporates defrosting water.

(Prior art) As a device for evaporating defrosting water in a refrigerated container,
In recent years, structures shown in FIGS. 6 to 8 have been considered. This refrigerator has a compressor 3, a cooling fan 4 for cooling the compressor 3, etc., and a water storage container 5 disposed in a machine room 2 provided at the bottom of the refrigerator body 1. The evaporator 6 is provided with its lower part inserted into the water storage container 5. and,
An overhanging portion 6a extending laterally is integrally formed on the top of each evaporator 6, and the overhanging portion 6a is positioned above the compressor 3.

In this case, defrost water from the cooler is received and stored in the water storage container 5, and the stored defrost water is distributed to each evaporator 6.
It is sucked up and evaporated from the surface of each evaporator 6.

(Problem to be solved by the invention' Since the cooling fan 4 is arranged perpendicular to the flow of the wind (see the arrow in FIG. 7), the wind from the cooling fan 4 hits only the evaporator 6 on the side closer to the cooling fan 4. Therefore, although the cooling fan 4 for cooling the compressor is provided, the wind generated by the cooling fan 4 does not contribute much to the evaporation of the defrosting water.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a defrost water evaporator for a refrigerator that can effectively utilize the wind generated by a cooling fan for cooling a compressor to evaporate defrost water and further improve the evaporation efficiency of defrost water. be.

[Structure of the Invention] (Means for Solving the Problems) The defrosting water evaporation device for a refrigerator of the present invention includes a compressor and a water storage container that receives and stores defrosting water in a machine room of the refrigerator body, and cools the compressor. A plurality of plate-shaped evaporators are arranged together with a cooling fan and suck up and evaporate the defrosting water in the water storage container.The lower part of each plate is inserted into the water storage container, and the air from the cooling fan is used to evaporate them. It is characterized by the fact that it is arranged so as to pass between each evaporator.

(Function) The defrosting water stored in the water storage container is sucked up by each evaporator and evaporated from the surface of each evaporator. At this time, when the cooling fan for cooling the compressor is driven, the wind from the cooling fan passes between each evaporator, so that the evaporation of the defrosting water is further promoted by the wind.

(Example) Hereinafter, a first example of the present invention will be described with reference to FIGS. 1 and 2.

The machine compartment 12 formed at the bottom of the refrigerator body 11 is open at the rear, and the rear opening 12a is closed by a back plate (not shown). A rotary compressor 13 is disposed horizontally in the approximate center of the machine room 12, and a cooling fan 14 for cooling the compressor 13 is disposed on the side of the compressor 13. These compressors 1 are installed in this machine room 12.
A defrosting water evaporator 15 is provided together with the cooling fan 14 and the like.

The defrosting water evaporator 15 includes a water storage container 16 with an open top and a plurality of plate-shaped evaporators 17. Among these, the water storage container 16 has an abbreviated shape with a narrow part 16a and a wide part 16b, the narrow part 16a is located behind the compressor 13, and the wide part 16b is connected to the cooling fan 14 of the compressor 13. It is arranged in the machine room 12 so as to receive and store defrosting water from a cooler (not shown) of the refrigerator main body 11. The evaporators 17 are made of a water-absorbing porous material such as ceramic sox, and their lower portions are inserted into the narrow part 16a of the water storage container 16 so that they are spaced apart from each other at a predetermined distance. It is provided in a state where it is supported by supporting means (not shown). And each evaporator 1
7 is integrally formed with an overhanging portion 17a that extends laterally, and each evaporator 17 has an overhanging portion 17a that extends sideward. a is located above the compressor 13, and is arranged with the tip facing toward the cooling fan 14 side and being oblique to the compressor 13.

Now, in the case of the above configuration, when the cooler is defrosted, the defrosting water from the cooler passes through the drain pipe (not shown) to the wide part 16b (::::::) of the water storage container 16, and the wide part 16b (::::: The defrosting water also flows to the side of the portion 16a and is stored in the water storage container 16.The defrosting water comes into contact with the lower part of each evaporator 17, is sucked up by capillary action, and is evaporated from the surface of each evaporator 17. When the compressor 13, which has been in the defrosting stop state, resumes operation, the compressor 13 generates heat, and the air warmed by the heat flows along the surface of the overhanging portion 17a of each evaporator 17. This promotes evaporation of the defrosting water from the surface of each evaporator 17.

Furthermore, the cooling fan 14 is connected to the compressor 1, for example.
When the cooling fan 14 is activated upon restart of the operation of the compressor 3, the air from the cooling fan 14 is blown toward the compressor 13, and the compressor 13 is cooled by the air. At this time, since each evaporator 17 is arranged obliquely with its tip facing toward the cooling fan 14, a portion of the air from the cooling fan 14 is directed to each evaporator 17 as shown by the arrow in FIG. The air passes between the overhanging portions 17a of the evaporators 17, and therefore, the air accompanied by the air warmed by the heat of the compressor 13 flows between the evaporators 17, and is removed from the surface of each evaporator 17. Evaporation of frost water is further promoted.

FIG. 3 shows a second embodiment of the present invention, which differs from the first embodiment in the following points.

That is, in the first embodiment, the cooling fan 1 for each evaporator 17
However, in this second embodiment, the plurality of evaporators 18 are located far from the cooling fan 14 (on the left side in the figure). The overhanging portions 18a are arranged so that the angle toward the cooling fan 14 side becomes larger in order, and the overhanging length of the overhanging portion 18a is made shorter in the order of the distance from the cooling fan 14.

According to the second embodiment, the wind generated by the cooling fan 14 can more easily flow between the evaporators 18, and the evaporation efficiency of defrosting water can be further improved.

Furthermore, FIGS. 4 and 5 show a third embodiment of the present invention, which differs from the first embodiment described above in the following points. That is, one water storage container 19 has a substantially rectangular shape, and a rectangular cylindrical portion 20 with both upper and lower sides open is formed in the center thereof. It is arranged as follows. The plurality of plate-shaped evaporators 22 are formed in a substantially U-shape, and their lower portions are inserted into the water storage container 19 so that they are spaced apart from each other at a predetermined distance and are supported by support means (not shown). ing. Each evaporator 22 is arranged along the longitudinal direction of the compressor 13 so as to follow the flow of the air from the cooling fan 14, and a plurality of evaporators 22 in the central part are arranged so as to straddle the cylindrical part 2o. has been done.

According to this third embodiment, since each evaporator 22 is arranged along the wind of the cooling fan 14, the wind flows more easily between each evaporator 22, and moreover, it is possible to fit the water into one water storage container. Since the stored defrosting water is warmed by the heat of the compressor 13, the evaporation efficiency of the defrosting water is further increased.

[Effects of the Invention] As is clear from the above description, according to the defrosting water evaporator for a refrigerator of the present invention, a plurality of plate-shaped evaporators that suck up and evaporate defrosting water are used for cooling a compressor. Since the cooling fan is arranged so that the air passes between each of these evaporators, the air from the cooling fan can be effectively used to evaporate the defrosting water, thereby further increasing the evaporation efficiency of the defrosting water. It has excellent effects.
