Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigerator, and more particularly to a refrigerator suitable for preventing vibration of a cover plate provided on the back of the refrigerator.

As a means of reducing the depth (when installed) of a refrigerator or as a means of improving the rear design, the compressor and condenser (conventionally installed exposed at the rear of the refrigerator) are generally housed in the machine compartment, and these compressor and condenser are There are many types of refrigerators on the market that use a blower to forcibly radiate heat from the refrigerator and condenser to the outside.

Also, recently, refrigerators that use the back plate of the refrigerator as a condenser and have an improved design for that part alone have become commercially available. However, refrigerators of the type that use the blower to forcibly release heat to the outside have a drawback in that the power consumption goes back by the amount of operating the blower. In addition, for the latter type of refrigerator where only the condenser serves as the back plate, the design of that part is improved, but the machine compartment where the compressor is housed is completely visible from the back, so the back design is This is not to say that the design of other refrigerator surfaces has improved. Furthermore, in the case of this type of refrigerator, the back plate of the refrigerator that serves as the condenser and the installation area must be installed with a space between it and the wall so as not to block the heat radiation of the previous condenser, so it is installed side by side. There was a defect in which items could be dropped from the sink or the like into the space formed between the back of the refrigerator and the wall.

In order to improve these defects, the present invention installs a cover plate over almost the entire length of the refrigerator to form a chimney between it and the back plate of the refrigerator, and transfers the heat from the compressor and condenser installed in the machine room to the chimney. In addition, heat is radiated outside by natural convection without using a blower, and this cover plate can be attached closely to the back wall, etc., to obtain an inexpensive refrigerator. .

The details of the present invention will be described below with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a refrigerator body. A machine room 7 is formed to house the 6. 9 is the interior 8 formed by the inner box 4
This is a door that closes the front opening of the Reference numeral 10 denotes a cover plate that is attached to the back plate 2a of the refrigerator with a slight interval (30 to 70 mm) therebetween. This cover plate 10 is the first
As shown in the figure, it is provided over the entire length of the refrigerator body and also covers the machine room 7 section. That is, this cover plate 10 has a chimney 1 between it and the refrigerator back plate 2a.
1. 12 is a decorative frame having a discharge port 13 attached to the upper end of the chimney 11. This decorative frame 12 also has a handle 14.
Also, it is very convenient to use the handle 14 when attaching the decorative frame 12 to the refrigerator body 1. 1
5 is a base forming the lower surface of the machine room 7. The lower end of the cover plate 10 is in contact with the base 15 to communicate the machine room 7 and the chimney 11. 16 is a suction port provided in the base 15. 17 is a wire condenser installed over the entire width of the suction port.

All of these are installed in the machine room 7 as shown in the figure, and the compressor 5 is located approximately below the chimney 11, and the wire condenser 17 is installed facing the air intake port. There is. 19 is a machine room cover that covers the front side of the machine room 7. 20
is a defrost water receiver (not shown in the figure, but it is a defrost water receiver used when frost adhering to the cooler is melted). Inside this defrost water receiver 20, there is a condenser 17 as shown in Fig. 2. A part of the defrost water is always in place and forcibly evaporates the defrosting water. 21 is a leg. The height of the legs 21 is approximately 20 to 50 mm, and provides a perfect distance between the lower surface of the base 15 and the floor surface when the refrigerator is installed. Reference numeral 22 denotes a fixture, and by providing this fixture 22 in a proper position, the cover plate can be attached as shown in FIG. 2, and the cover plate (usually a thin iron plate) can be prevented from becoming bent.

Heat exchange between the condenser and compressor of the refrigerator having such a configuration and outside air is achieved by first sufficiently exchanging heat with the condenser 17 by the air that enters approximately perpendicularly to the wire condenser 17 from the suction port 16 on the bottom surface of the condenser 17; Next, the temperature of the condenser 17 leading to the compressor 5 is usually 40 to 50 degrees Celsius, so it further exchanges heat with the compressor 5, which is at a temperature of around 70 degrees Celsius to 80 degrees Celsius, becoming lighter and rising inside the chimney 11. . At this time, the chimney 11 serves to collect high-temperature air that has passed through the condenser 17 and compressor 5.
Due to the natural convection that occurs in this way, this refrigerator achieves the same effect as conventional refrigerators that use a blower to dissipate heat. Reference numeral 23 denotes sashes made of synthetic resin or the like that are fixed to both ends of the back of the refrigerator.
As shown in FIG. 3, this sash 23 consists of a rising portion 23a, a clamping portion 23b, and a mounting portion 23c, and the cover plate 10 described above is inserted into the clamping portion 23b.

Normally, this sash is installed so that the rising portion 23a is positioned substantially on the same plane as the side plate 2b of the inner box 2 forming the refrigerator body, but it may be installed with a slight offset.

Therefore, the cover plate 10 is attached after the sash 23 is attached to the refrigerator main body by utilizing the elasticity of the cover plate 10 itself, and consideration is given so that the heads of the mounting screws etc. do not appear on the surface of the cover plate 10. ing.

In addition, the lower end of the cover plate 10 contacts the base 15 etc. as described above, and that part is fixed.
The upper end is a holding groove 1 of the decorative frame having a discharge port, a handle, etc.
It has a structure that is inserted into 2a and fixed.

As explained above, the present invention provides a machine room provided on the back side of a refrigerator, a cover plate provided on the back side to cover the machine room and the back side, and a gap between the cover plate and the back side. The refrigerator includes a chimney that is formed in the refrigerator and opens at the upper surface of the refrigerator, and the refrigerator includes a sash provided on the extensions of both side plates of the back surface, and a holding part provided on the sash, Both sides of the cover plate are inserted, the lower end of the cover plate is attached to a base constituting the machine room, and the upper end is attached to a clamping groove of a frame constituting the upper surface of the refrigerator. Because it is a refrigerator, it is possible to radiate heat from the compressor and condenser to the outside without installing a blower like in the past, improve the back design, and prevent items from falling on the back of the refrigerator when the refrigerator is installed. This allows the refrigerator to be installed as close to the back wall as possible.

In addition, according to the present invention, all four sides of the cover plate are fixed by the sash, base, and frame, so the cover plate can be securely fixed to the back of the refrigerator, so it will not vibrate due to vibrations from the refrigerator. Since the cover plate is less likely to vibrate, it is possible to provide a low-noise refrigerator with both plates.
