Description

[Detailed description of the invention] The invention relates to a refrigerator, and in particular, a condenser is installed at the bottom of the refrigerator.
In addition to compactly arranging the compressor, evaporation plate, etc., the noise of the compressor is reduced, and the cooling efficiency of the condenser and compressor is improved.
The present invention relates to a refrigerator with improved evaporation efficiency of an evaporating dish.

Generally, a refrigerator has a condenser, compressor, etc. as external equipment.
It has an evaporating dish etc.

Since the compressor generates noise, it is installed at the bottom of the refrigerator together with the evaporating dish, while the condenser generates a large amount of waste heat when exchanging heat, so it is installed at the back of the refrigerator.

Furthermore, in order to improve the cooling efficiency of the condenser, the refrigerator had to be installed away from the walls of the room, making it impossible to effectively utilize the floor space of the kitchen.

Therefore, as shown in FIG. 1, in order to make effective use of the floor space, a condenser may be installed at the bottom of the refrigerator, and the condenser may be cooled by a blower fan.

As shown in the figure, a compressor 1, a condenser 2, an electrical component box 3, and an evaporating dish 4 are provided at the bottom S of the refrigerator, and each is partitioned by a partition wall.

Further, a ventilation fan 7 is provided on a partition wall 6 that partitions the condenser 2 and the compressor 1, and is configured to cool the condenser 2 and the compressor 1.

Further, a hot air flow 9 is provided on the outer side 8 of the partition wall 5 that partitions the compressor 1 and the evaporating tray 4, and the warm air 10 that has been heat exchanged in the condenser 2 and the compressor 1 is transferred to the evaporating tray. 4.

In addition, an exhaust hole 1 is provided on the same partition wall surface as the partition wall 12 in which the suction hole 11 is provided, and the partition wall 13 that partitions the evaporating dish 4 is provided with an exhaust hole 1.
4 is provided, and is configured to discharge the hot air that has flowed through the evaporating dish 4.

Therefore, by driving the ventilation fan 7, the suction hole 1
The cold air 16 and 22 sucked in from the air filters 1 and 15 undergoes heat exchange in the condenser 2 and the compressor 1, becomes hot air 10, and flows into the evaporating dish 4 via the hot air flow 9.

Furthermore, this hot air 10 heats the evaporating dish 4 and is discharged from the exhaust hole 14.

At this time, the partition wall 5.6 becomes a sound insulating wall and can reduce the noise generated by the compressor 1 and the like.

However, since the hot air 10 flowing in from the hot air flow population 9 has air convection only on a part (approximately half in the illustrated example) of the surface of the evaporating dish 4, its evaporation efficiency is poor, and the hot air 10 discharged from the exhaust hole 14 Since the direction of the hot air 10 is slightly inclined toward the suction hole 11, the discharged hot air 10 is immediately sucked through the suction hole 11.

As a result, a problem arises in that the cooling efficiency of the condenser 2 and the compressor 1 is poor, making it unsuitable for practical use.

The present invention was devised in order to focus on the above-mentioned problems and to effectively solve them.

The purpose of this invention is to install a condenser, compressor, evaporation tray, etc. at the bottom of the refrigerator to make the arrangement of external equipment more compact, and to forcibly cool the condenser and compressor with a blower fan. An object of the present invention is to provide a refrigerator that reduces noise by providing a partition wall that partitions them, a hot air flow population, and a deflection plate, improves the cooling efficiency of a condenser and a compressor, and improves the evaporation efficiency of an evaporation plate. .

Hereinafter, a preferred embodiment of the present invention will be described based on FIG. 2.

Arrows in the figure indicate air flow. As shown in FIG. 2, the configuration of the present invention is approximately the same as the configuration shown in FIG. details.

First, a hot air flow 9 is formed on the outer side 8 of the partition wall 5 that partitions the compressor 1 and the evaporating dish 4, and a warm air flow 18 is also formed on the inner side 17 of the partition 5. ing.

Furthermore, the hot air flow plate 9 is provided with a deflection plate 20 having one end fixed to the partition wall 19 and the other end facing the evaporation plate 4, so as to change the direction of the hot air flowing into the hot air flow force 9. It is composed of

In addition, an exhaust hole 1 is provided on the same partition wall surface as the partition wall 12 in which the suction hole 11 is provided, and the partition wall 13 that partitions the evaporating dish 4 is provided with an exhaust hole 1.
4 is provided.

The operation of the present invention constructed as above will be described.

By driving the blower fan 7 provided between the condenser 2 and the compressor 1, the cold air 16 sucked in from the suction hole 11 flows into the condenser 2 through the ventilation hole 21, and also flows from the suction hole 15. The cold air 22 flows directly into the condenser 2.

This cold air 16.22 undergoes heat exchange in the condenser 2 and then warm air 2
3.24, and the air is blown to the compressor 1 side by the air blowing fan 7.

Furthermore, after this warm air 23 undergoes heat exchange with the compressor 1, a part of it is discharged from the exhaust hole 25.

Most of the warm air 23 is reflected by the partition wall 19, and
The hot air flows into the evaporating dish 4 via the hot air flow 9.

At this time, the warm air 26 flowing into the hot air flow population 9 near the partition wall 5 in an oblique direction with respect to the lateral direction of the evaporating dish 4 is caused to flow in the longitudinal direction of the partition wall 5 due to the entrainment phenomenon that occurs between the partition wall 5 and the partition wall 5. Can be bent.

On the other hand, the hot air 24 blown by the blower fan 7 is sent to the evaporating dish 4.
The hot air flows into the evaporating dish 4 from a hot air flow hole 18 formed on the inner side 17 of the partition wall 5 in a diagonal direction with respect to the lateral direction.

Here, this hot air 24 and the hot air 26 bent in the longitudinal direction of the partition wall 5 mutually flow into the evaporating dish 4 from substantially opposite directions via the partition wall 5, so they collide with each other and interfere with each other. Become.

As a result, the hot air 24 and the hot air 26 flow approximately linearly along the vertical direction of the evaporating dish 4 and are linearly discharged from the exhaust hole 14 to the outside of the system.

On the other hand, the hot air 27 that flows into the hot air flow population 9 near the deflection plate 20 in an oblique direction with respect to the lateral direction of the evaporation plate 4 flows through the deflection plate 20.
The evaporating dish 4 is bent in the vertical direction due to the entrainment phenomenon that occurs between the two.

Therefore, the hot air 27 flows substantially linearly along the longitudinal direction of the evaporating dish 4, and is linearly discharged from the exhaust hole 14 to the outside of the system together with the hot air 24,26.

In short, the warm air 24, 26, 27 flows throughout the evaporating dish 4 and is discharged straight from the exhaust hole 14, so the exhausted hot air 24, 26, 27 flows on the same partition surface as the exhaust hole 14. It is not immediately inhaled through the provided suction hole 11.

In the above embodiment, the warm air flows 9 and 18 are respectively formed in the inner part 17 and the outer part 8 of the partition wall 5 that partitions the compressor 1 and the evaporating dish 4, but the invention is not limited to this. The evaporation efficiency of the evaporation plate 4 may be increased by forming a hot air flow in the evaporation plate 5 .

According to the present invention, the following excellent effects are exhibited.

1. Since hot air flows throughout the evaporating dish and the discharged hot air is not directly sucked in, the evaporation efficiency of the evaporating dish and the cooling efficiency of the condenser and compressor can be greatly improved.

2. The partition wall acts as a sound insulating wall and can reduce the noise generated by the compressor, etc.

3. Since the refrigerator can be placed close to the wall of the room, the floor space of the installation location can be used effectively.
