Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a refrigerator with an improved structure for evaporating defrost water.

[Technical background of the invention]

Conventionally, this type of refrigerator has a machine room that extends from the front to the rear in the lower part of the outside of the refrigerator.
A compressor is placed at the rear of this machine room, and a hot gas pipe connected to the discharge port of the compressor is placed at the front in a meandering manner along the base plate, etc. An evaporation plate is arranged to receive the defrosted water that is led from the pipe through a drainage hose, etc., and the defrosted water is evaporated by the heat of the hot gas (high-temperature gaseous refrigerant) passing through the pipe. .

[Problems with background technology]

However, according to the above-mentioned conventional system, because the machine room is secured in the lower part of the outside of the refrigerator from the front to the rear, the bottom of the refrigerator has to be raised by at least 100 mm, and the There is a problem that the volume inside the compartment becomes smaller, and if you try to secure a large volume with the same structure, you will have no choice but to increase the height of the whole refrigerator, which will make it difficult to use and will not be stable during earthquakes. There was a problem that caused it to be missing. Another problem was that a special hot gas pipe was required to evaporate the defrosted water received by the evaporating dish, and in addition, the evaporating dish was visible at the bottom of the refrigerator, making it unsightly. .

[Purpose of invention]

The present invention was made to solve the above-mentioned conventional problems. Namely, it is possible to secure a large capacity without increasing the height of the warehouse, and there is no need for special hot gas pipes. The idea is to provide a refrigerator that can also look good.

[Summary of the idea]

The present invention provides a machine room in which the compressor is located at the rear lower part of the outside of the refrigerator, and a cover that closes the opening on the back of the machine room. The evaporating dish is characterized in that a dish is placed on the compressor via an elastic body so that defrosted water drawn out from inside the refrigerator is received by the evaporating dish and evaporated.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings. First, in FIG. 4 is the refrigerating room formed below it.
Further, there is a normal temperature storage chamber formed below the storage chamber, which has doors 5, 6, and 7, respectively. In addition, in the above room temperature storage chamber 4, as shown in Fig. 2, one rear half (left side in the figure) is left and the other half (right side in the figure) is turned inward. It has a concave shape, and the concave part forms a machine room 8 whose back and bottom surfaces are open at the rear lower part outside the main body 1, that is, at the rear lower part outside the refrigerator. 9 is the machine room 8 as shown in Figures 3 and 4.
This is a compressor stand that is arranged so as to leave front and rear gaps 10 and 11 in the open part of the lower surface.The compressor 12 is placed and fixed on the upper surface of this, so that it can be installed inside the machine room 8, especially in the lower part. A compressor 12 is arranged. For example, a screw 13 (not shown) is inserted into the opening on the back side of the machine room 8.
This is a cover that is attached to the cover to close the area, and has a plurality of slit-shaped heat dissipation ports 14 formed in the upper part, for example, six, and a substantially rectangular evaporating dish inlet/outlet 15 in the lower center of the cover. Furthermore, a crosspiece 16 is formed on the upper side of the entrance 15, and a step 17 is formed on the lower side. and 1
Reference numeral 8 denotes an evaporation dish, which is also shaped like a rectangular container in its entirety, and has a rounded protuberance 19 formed on its bottom wall as a relief from the top surface of the compressor 12. At the same time, a projection 20 is provided to protrude downward from the central portion, and an elastic body such as a rubber cushion 21 is attached to this projection 20. or,
A small cover 22 of a size that can close the evaporating dish inlet/outlet 15 of the cover 13 is integrally formed in the front part of the evaporating dish 18, and furthermore, a hook part 23 is provided on the upper side of the small cover 22, and a hook part 23 is provided on one side. , a leg portion 24 is formed on the lower side. Therefore, while holding the small cover 22 and placing the evaporating dish 18 into the machine room 8 through the evaporating dish entrance/exit 15 of the cover 13, the hook part 23 is engaged with the crosspiece part 16, and the leg part 24 is attached to the stepped part 17. In this way, the evaporating dish 18 is supported by the cover 13 and placed on the compressor 12 via the rubber cushion 21. In addition to the above, reference numeral 25 shown in FIG. 1 is a drain hose that guides defroster water from the inside of the refrigerator, and the evaporation plate 18 arranged as described above also faces the lower end of the drain hose 25.

Therefore, in the case of the above configuration, the drain hose 25
The defrost water drawn out from inside the refrigerator through the drain hose 25 falls into the evaporation tray 18 and is stored therein, and the stored defrost water is drawn out from the compressor 12 below the evaporation tray 18. The evaporation process is carried out successively by receiving the emitted heat and the heat in the surrounding high-temperature atmosphere. In particular, in the case of this embodiment, the machine room 8 where the evaporating dish 18 is located
Inside, as shown by arrows in FIG. 4, air escapes from the gaps 10 and 11 in front and rear of the compressor table 9 below to the heat dissipation port 14 at the top of the cover 13, so that the evaporation of the defrost water is even more active. become. In addition, since the evaporating dish 18 is placed on the compressor 12 via a rubber cushion 21, that is, an elastic body,
Even if the compressor 12 generates vibrations, the vibrations will not be transmitted to the evaporating tray 18, thereby preventing the occurrence of chattering noise, etc., and not only that, but also if a large amount of defrosted water accumulates and increases the weight of the evaporating tray 18. Since the elastic body (rubber cushion 21) bends to lower the evaporating tray 18 and bring it closer to the compressor 12, which is the heat source, the evaporation of the defrosted water in the evaporating tray 18 can be further promoted, which is advantageous.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but may be implemented with appropriate changes, particularly in the specific shapes of each part, etc., without departing from the spirit of the invention.

[Effect of the invention]

As is clear from the above, the present invention does not particularly require a machine room below the warehouse.
The bottom can be lowered to the lowest point, securing a large volume without increasing the overall height, making it easier to use and improving stability in the event of an earthquake, etc. . In addition, since the heat radiation of the compressor can be used to evaporate defrost water, there is no need for special hot gas pipes, etc.
Accordingly, the structure can be simplified and the price can be lowered, and in addition, the evaporating dish can be made invisible and the appearance can be improved. Furthermore, the vibrations of the compressor are not transmitted to the evaporating dish, preventing the occurrence of chattering noise.
In addition, it has many excellent practical effects, such as the advantageous evaporation effect that depends on the amount of defrosting water.
