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, accordingly, their heights have also tended to increase. However, conventional refrigerators have a machine room at the bottom of the refrigerator body that houses 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.
In this refrigerator, a compressor and a condenser are housed in the machine room, and a heat dissipation port is formed in the front of the machine room to dissipate the heat inside the machine room to the outside. I have to.

3 Problems with the Prior Art The above-mentioned refrigerators had a problem with noise, such as the operating noise of the compressor generated in the machine room leaking directly to the outside through the heat radiation opening.

4. Purpose of the invention The purpose of the invention is to provide a refrigerator that can reduce noise.

5. Structure of the invention The invention is characterized in that a condenser and a compressor are arranged in the machine room in order from the radiator side toward the back, and a metal plate is attached to the condenser so as to face the compressor. This is a refrigerator.

6 Embodiment of the invention An embodiment of the invention will be described below with reference to the drawings. First, in Fig. 1, reference numeral 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 body 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 radiation 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. A condenser 17 and a compressor 14 are arranged in order toward the back. 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, 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 transferred to the freezer compartment cooler 4. and is supplied to the cooler 8 for the refrigerator compartment. 23 is the heat radiation port 13 of the machine room 12
This is a decorative cover made of plastic, for example, which is attached to a louver-shaped cover having a large number of wind direction pieces 24 extending in the left-right direction. An inverted U-shaped partition portion 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.

Now, according to this embodiment configured as described above,
You can get the following effects. That is, the machine room 12
Since the condenser 17 and the compressor 14 are arranged in order from the heat radiation port 13 to the back, the operating sound of the compressor 14 does not directly leak out from the heat radiation port 13 to the outside, but is shielded and reflected by the condenser 17. Moreover, since the condenser 17 is provided with a plate 21 facing the compressor 14, the operating sound of the compressor 14 is also shielded and reflected by the plate 21.
As a result, the leakage of operating noise to the outside of the machine room 12 can be prevented as much as possible, the operating noise can be greatly reduced, and overall noise can be greatly reduced. Also, in this case, the condenser 17
A sound absorbing effect can also be obtained by the sound absorbing member 22 provided in the
It is more effective in reducing noise. Furthermore, plate material 2
1 is made of aluminum, so it has excellent heat dissipation.
The heat dissipation effect of the condenser 17 can also be improved.

7. Effects of the Invention As is clear from the above description, the present invention can provide a refrigerator that can significantly reduce noise and improve the heat dissipation effect of the condenser.
