Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a refrigerator having an improved structure for dissipating heat from a machine room.

[Technical background of the invention] Conventionally, this type of refrigerator has been provided with a machine room 1 that houses a compressor (not shown) in the lower part of the back as shown in FIG. A machine room cover 2 is provided, and a ventilation duct part 3 is provided on the side part.The ventilation duct part 3 allows ventilation between the machine room cover 2 and the wall surface even when the back part is pressed against the wall. can be secured,
Thus, a device is provided that is configured to ensure as good heat dissipation as possible from the machine room 1 while reducing the installation space.

[Problems with the Background Art] However, in the above-mentioned device, the ventilation hole 4 of the machine room cover 2 is located only in the center, and therefore, heat dissipation in the machine room 1 is carried out through the ventilation hole in the center of the machine room cover 2. 4, and almost no heat is radiated through the ventilation duct section 3. Also, heat radiation performed through the ventilation hole 4 in the center of the machine room cover 2 is blocked by the wall when it is installed against a wall. As a result, the heat dissipation of the machine room 1 deteriorates, leading to problems such as shortened compressor life and increased power consumption. However, there were problems such as the need for special equipment. Moreover, in this case, since the heat is released only from the vent 4 in the center of the machine compartment cover 2, the temperature at the back of the entire refrigerator rises, causing a problem in that the cooling performance inside the refrigerator is also reduced.

[Purpose of the invention] The present invention was made in view of the above-mentioned circumstances, and its purpose is to improve heat dissipation from the machine room without requiring any special equipment, and to reduce temperature rise at the back of the refrigerator. Our goal is to provide an excellent refrigerator that can save you a lot of money.

[Summary of the invention] The present invention forms a ventilation hole facing the ventilation duct section on the side of the machine room cover, and a vent hole facing the ventilation duct part on the inner surface of the machine room cover that protrudes toward the inside of the machine room and faces the ventilation hole. It is characterized by being provided with a rib-shaped heat dissipation guide that rises and slopes upward, thereby allowing heat to be actively dissipated from the machine room through the ventilation duct section.

[Embodiment of the invention] An embodiment of the invention will be described below with reference to FIGS. 1 to 3. First, in Figure 1, 11
is a refrigerator main body, which has a machine room 13 in the lower part of the back that houses a compressor 12 shown in FIG. 3, and a machine room cover 1 that shields the machine room 13.
4, and has a ventilation duct part 15 on the side. The machine compartment cover 14 is formed as shown in FIG. 2 in detail, and has a large number of ventilation holes in the center portion flush with the back of the refrigerator body 11 excluding the ventilation duct portion 15. 16, and the bulging part 17, which is bulged from both sides flush with the ventilation duct part 15 and formed so that the upper part faces the ventilation duct part 15, has a slanted part with the upper part. Ventilation holes 18 and 19 are formed on the back side, respectively. Furthermore, in the central part of the machine room cover 14, a flat V-shaped rib is provided on the inner surface thereof, which protrudes toward the inside of the machine room 13 and slopes upward toward the vent hole 18 on the upper surface of the bulge part 17. A heat radiation guide 20 is formed. As shown in FIG. 3, the heat dissipation guide 20 is formed so that its protruding tip side overlaps the compressor 12 in the machine room 13 by a distance l.

In the case of the above configuration, the machine room 13
In particular, hot air released from the compressor 12, which is the largest heat source, rises along the heat radiation guide 20 and reaches the vents 18, 19. In particular, it is discharged from the ventilation opening 18 into the ventilation duct section 15 and then upwardly through the ventilation duct section 15. Therefore, in the case of this embodiment, machine room 1
3 can actively radiate heat through the ventilation duct portion 15, thereby extending the life of the compressor 12 and reducing power consumption. Further, there is no need for special equipment such as an oil cooler, and the above-mentioned vents 18, 19, especially the vents 18 and the heat radiation guide 2 are provided in the machine room cover 14.
Since it is only necessary to provide 0, the cost can be kept low. Furthermore, as described above, heat can be actively radiated exclusively from the vent 18 through the ventilation duct section 15 by being guided by the heat dissipation guide 20 of the machine compartment cover 14, and from the vent 16, that is, from the center of the machine compartment cover 14 to the refrigerator body. Since the amount of heat emitted along the back of the refrigerator body 11 can be reduced, the rise in temperature at the back of the refrigerator main body 11 can be suppressed accordingly, and the cooling performance inside the refrigerator can also be maintained at a high level.

Note that the ventilation duct portion 15 is not limited to one in which the periphery thereof is open, but may be shielded.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but may be implemented with appropriate modifications within the scope of the gist.

[Effect of the invention] As is clear from the above description, according to the invention,
By improving heat dissipation from the machine room without requiring any special equipment, it is possible to extend the life of the compressor, reduce power consumption, and keep costs low. It has various excellent effects, such as being able to keep the temperature rise in the refrigerator to a small level and maintain high cooling performance inside the refrigerator.
