Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the invention of a refrigerator that can be installed by fitting the back of the refrigerator tightly against a wall, etc., and also has the ability to be installed as a built-in refrigerator. Generally, compressors and condensers (conventionally, four are installed on the α side of the refrigerator) are used as a means to improve the design of the back of the refrigerator.
are stored in the machine room, and the heat radiated by these compressors and condensers? There are many so-called built-in refrigerators on the market that use a blower to forcibly radiate heat to the outside. However, since this type of refrigerator uses a blower, it is difficult to use. [1fi ((Of course, there are major drawbacks such as the extra cost of air.)

In order to improve these defects, the present invention installs a back duct plate and a ceiling duct plate that form a duct between the back plate and ceiling plate of the refrigerator over almost the entire width of the refrigerator, and also installs a partition plate inside the duct. The heat from the compressor is radiated to the outside by the chimney effect, and the heat from the condenser is radiated to the outside by the chimney effect and one of the double-shaft fans.The design effect is achieved without compromising the original performance of the refrigerator. The aim is to improve the installation performance as well as improve the installation performance.

The details of the present invention will be explained below using an example shown in the drawings.
1 is the refrigerator body, this refrigerator body 1 is old insulation material from Sotoi City 29 6. It is made up of an inner box 4 and the like, and forms a machine room 7 in which a compressor 5 is housed in the lower part. 6 is a condenser, and 9 is a door that closes the front opening of the interior 8 formed by the inner box 4.

Reference numeral 10 denotes a back duct plate that covers the back plate 2a of the refrigerator to which the condenser 6 is attached and the back of the machine room 7. 11
is a ceiling duct plate installed on the ceiling surface of the refrigerator, and an a heat grill 12 is attached to the front. The back duct plate 10 and the ceiling duct plate 11 form a duct 16 almost entirely between the back plate 2a and the ceiling plate 2b of the refrigerator main body 1 as shown in the figure, and the compressor 5 and compressor 6 are used to The radiated heat is evacuated from the duct 16. 14 is a base forming the lower surface of the machine room 7. The lower end of the rear duct plate contacts this base 14 and communicates the machine room 7 with the duct 16. 15 is a suction port provided in the base 14. Reference numeral 16 denotes a partition plate that partitions the inside of the duct 16. The partition plate 16 divides the inside of the duct 16 into a passage 15a through which air passes through the compressor 5 and a passage 13b through which the air passes through the condenser. The lower end of this partition plate 16 is connected to the base 1.
It is measured a little further apart from the top of the fourth surface, and the interval is approximately half of the total height of the compressor 5. This is to introduce fresh air from the surrounding area through the suction port 15 provided in the base 14, partly into the passage 16a and partly into the passage 16b. On the other hand, the curved end extends to the vicinity of the heat exhaust grill 12, and the passages 13a are formed by partition plates 16 at approximately equal intervals. 17 is a cooler for cooling the inside 8 of the refrigerator; The blower 18 is a blower that forcibly circulates the cold air that has passed through the cooler 17 to the inside of the refrigerator.The blower 18 is a two-hole type shown in FIG. The fan 18b for cooling the inside of the refrigerator also forces the air that has passed through the condenser 6 to the shaft outside the refrigerator.
A fan 18C is installed to radiate heat from the heat exhaust grill 12. This fan 18C is generally a turbo fan and requires a casing 19C.

20 is a heat exhaust grill 1 for discharging the heat from the condenser that has passed through the casing 19.
This is a guide plate that leads out from 2. A portion of this guide plate 20 is close to the opening 19H of the 751 casing 19, and the other end extends to the non-thermal grill 12.
Moreover, it is also expanded to the υF+ heat grill 12 side.

This is because the opening area is narrowed by the facing lip 12a provided on the heat exhaust grill 12, so the casing 1
This is done to keep the area approximately equal to that of the opening 19a of No.9. (The narrower the opening area, the worse the heat dissipation effect will be.) In addition, the wind direction lip 12a of the heat exhaust grill 12 is generally
It is oriented upward as shown in FIG. 2 so that the lice are released upward. (This is to prevent the wind from hitting the person's face and causing a sense of discomfort.) 21 is the foot. The height of the legs 21 is about 20 to 50 mm, and is designed to provide a perfect distance between the lower surface of the base and the floor surface when the refrigerator is installed.

As explained above, the present invention is directed to a back tact plate that completely destroys the back of a refrigerator to which a condenser is attached, including a machine room with a built-in compressor, and the entire ceiling surface of the refrigerator.

A ceiling duct board is installed to cool the air! 1. A groove is formed by a heat exhaust grill consisting of an upwardly shaped wind direction rib that forms a ventilation hole in the front part of the upper part, and the lower part forms a duct that communicates with the machine room, and the compressor is installed in the duct. A partition plate is provided to separate the passage of air through which the air passes through.The lower end of this partition plate extends from the base surface of the lower part of the +4 compartment to approximately half the total height of the compressor, and the other end extends to the vicinity of the exhaust heat grill. In addition, a blower is installed on the side of the passageway containing the condenser, and the heat from the compressor is transferred through a duct using the chimney effect by natural convection.
The heat of the condenser is forcibly radiated to the outside using the chimney effect plus the help of one fan of the double-shaft blower, so it covers the entire area of the refrigerated fLW surface, improving the design effect and improving performance. There is no such thing as deterioration of the /J theory, and in general @+J poetry, even if the back of the refrigerator is placed tightly against the wall, its performance is fully guaranteed.

In terms of installation space, it can be installed on the back of a conventional refrigerator,
Unlike refrigerators in which the condenser is exposed to the outside, there is no need to set the refrigerator at a distance of about 10011II+1 from the wall, resulting in a space-saving type. Additionally, by providing a ceiling duct board, it can also be used as a built-in device. Furthermore, there is no need for a separate feeder used in the conventional built-in type, so there is no cost for component air, making it a power-saving type.
