Description

[Detailed Description of the Invention] 1. Technical Field of the Invention The present invention relates to a refrigerator having a machine room in the upper part of the refrigerator body.

2. Prior Art In recent years, household refrigerators have tended to become larger and, along with this, their heights have also tended to increase. However, conventional refrigerators have a machine room at the bottom of the refrigerator body that stores the compressor, etc., so if such a conventional refrigerator were to be enlarged, the user's room would be located at the top of the refrigerator body. Therefore, in recent large refrigerators, the height of the refrigerator body is lowered by installing a mechanical room in the upper part of the refrigerator body, and the interior of the refrigerator body is lowered. Products with wider space are also appearing.
Therefore, in this refrigerator, in addition to storing and arranging the compressor and condenser in the machine room, a heat radiation port is formed in the front of the machine room, and the heat inside the machine room is naturally radiated to the outside through the heat radiation port. I'm doing it like that.

3 Problems with the Prior Art In the above-mentioned refrigerator, there was a problem in that the heat dissipation through the heat dissipation ports was not very active, and therefore the heat dissipation of the condenser was low and the degree of condensation of the refrigerant in the condenser was slow.

4. Purpose of the invention The purpose of the invention is to provide a refrigerator that can improve the heat dissipation of the condenser.

5. Structure of the invention The present invention has a louver-shaped partition part having a large number of wind direction pieces in the heat dissipation port and protrudes inward at approximately the middle part in the vertical direction, and at least a wind direction piece below the partition part. This refrigerator is characterized by being equipped with a decorative cover that is formed so as to face outward and slope upward.

6 Embodiment of the invention An embodiment of the invention will be described below with reference to the drawings. First, in Fig. 1, 1 is the refrigerator main body, which is composed of an outer box 2, an inner box 3, and a box-shaped freezer compartment cooler 4, with a heat insulating material 5 filled between them. The inside of the container 4 is a freezing chamber 6, and the inside of the inner box 3 is a refrigerating chamber 7. A refrigerator compartment cooler 8 is disposed within the refrigerator compartment 7. In addition, 9 is a door for the freezer compartment, and 10 is a door for the refrigerator compartment. Now, the first
In the figures and FIG. 2, reference numeral 11 denotes a box disposed on the upper part of the storage body 1, and the inside of this is a machine room 12. It is said that And this box body 11
A plurality of ventilation holes 11a are formed in the back plate portion. 14 is a compressor, which is disposed at the back of the machine room 12 via a support stand 15, rubber legs 16, and the like. Reference numeral 17 denotes a condenser, and as shown in FIG. 3, this condenser is constructed by attaching multiple heat dissipation wires 19 to a condensing pipe 18 bent in a meandering manner, and has an L-shape as a whole. In this case, the heat radiation wire 19 is not attached to the curved portion 17a of the condenser 17.
As shown in FIG. 2, this condenser 17 is disposed on the side of the heat radiation port 13 of the machine room 12 via a support 20, so that it can be connected to the back of the machine room 12 from the side of the heat radiation port 13. Condenser 17 and compressor 1
4 are arranged. A thin metal plate 21 made of metal, for example, aluminum, is attached to the curved portion 17a of the condenser 17 so as to face the compressor 14, and is further attached to the heat radiation port 13 side of the curved portion 17a of the condenser 17. A sound absorbing member 22 made of, for example, a soft foam tape is attached to a plate material 21. Here, the refrigerant inlet (not shown) of the condenser 17 is connected to the discharge port of the compressor 14 through a heat radiation pipe (not shown).
This heat sink is connected to the compressor 1 through
The refrigerant flows from the discharge port 4 to the refrigerant inlet of the condenser 17 through the front, bottom, back, etc. of the storage body 1 . As a result, the high-pressure and high-temperature vaporized refrigerant discharged from the compressor 14 radiates heat and becomes liquefied (condensed) in the heat radiation pipe and condenser 17, and the liquefied refrigerant is supplied to the freezer compartment cooler. 4 and a cooler 8 for the refrigerator compartment. 23 is the heat radiation port 1 of the machine room 12
3 is a decorative cover made of plastic, for example, and is shaped like a louver and has a large number of wind direction pieces 24 extending in the left-right direction. An inverted U-shaped partition part 25 is formed at approximately the midpoint in the vertical direction of the decorative cover 23, and the wind direction pieces 24 are each formed to be inclined outwardly and upwardly. ing.

In the above configuration, consider a case where the compressor 14 is operated and the refrigeration cycle is operated. In this case, since the high-temperature vaporized refrigerant from the compressor 14 is flowing through the condenser 17, the air in the machine room 12 is heated by this heat and rises, causing the partition portion 25 of the decorative cover 23 to rise. Air flows out from between the upper wind direction pieces 24, and as a result, outside air is sucked into the machine room 12 from between the lower wind direction pieces 24 of the partition part 25, and the condenser 17 radiates heat to the air, which is connected to the partition. The air flows out from between the air direction pieces 24 above the part 25, that is, the air flow shown by the arrow A in FIG. This can promote heat dissipation from the condenser 17.

As described above, according to this embodiment, since the partition portion 25 that projects inward is provided at the vertically intermediate portion of the decorative cover 23, the heat dissipation of the condenser 17 can be greatly improved.

By the way, in this type of large refrigerator, the lower part of the heat dissipation port 13 of the machine room 12 is often at the height of a person's head. There was a problem.

In this regard, according to this embodiment, since the wind direction piece 24 of the decorative cover 23 is tilted outward and upward, the inside of the machine room 12 is not exposed from the lower part of the heat dissipation port 13, and the appearance is improved. can be achieved. In order to obtain this effect, at least the wind direction piece 24 below the partition portion 25 among the wind direction pieces 24 may be configured to face outward and be inclined upward.

Furthermore, according to this embodiment, the wind direction piece 24 of the decorative cover 23 can refract the operating sound of the compressor 14 diagonally upward, thereby making it possible to reduce noise.

7. Effects of the invention As explained above, the present invention provides a refrigerator that can form an air flow that contributes to the heat radiation of the condenser in the machine room, greatly improving the heat radiation performance of the condenser, and also improving the appearance. obtain.
