Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a refrigerator in which a refrigeration cycle condenser and compressor are disposed in the lower part of the refrigerator main body.

Conventional refrigerators of this kind have a refrigerated storage compartment inside, and a base plate attached to the bottom of the refrigerator body is divided into a left chamber and a right chamber by a partition plate, and the front of the left chamber is The condenser and compressor of the refrigeration cycle are installed on the base plate so as to be located on the side and rear sides, and a fan motor is installed in the communication port formed on the rear side of the partition plate. The structure is such that air is sucked into the left chamber and then discharged to the front side through the communication port and the right chamber to cool the condenser and compressor.
The back of the refrigerator body can be placed in close contact with an indoor wall, etc.

However, according to the above-mentioned conventional configuration, the capacitor, which is located at the front side of the left chamber and has a relatively large height dimension, is mounted on the base plate, so the distance between the base plate and the bottom wall of the refrigerator body is small. The dimensions had to be increased, which resulted in the problem of reducing the internal volume of the refrigerator compartment.Also, the operating noise of the compressor and fan motor was emitted directly to the front, resulting in an increase in noise. . The present invention has been made in view of the above-mentioned circumstances, and its object is to provide a machine in which the interior is used as a storage room, and the bottom surface of the refrigerator body is opened at the rear lower part of the refrigerator body so that the rear part of the bottom wall of the refrigerator body bulges upward. A chamber is formed, and a base plate having an intake/port on one of the left and right ends and an exhaust port on the other side is installed in the lower open part of this machine room, and the compressor and condenser of the refrigeration cycle are installed on this base plate. By arranging the cooling fan motors in a row on the left and right, the internal volume of the storage chamber can be increased, and the operating noise of the compressor and fan motors can be minimized to reduce noise. Provides a refrigerator that can be made small. An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a refrigerator main body consisting of an insulated casing with a refrigerator compartment 2 serving as a storage room, and a machine room at the rear lower part of which is opened at the bottom and rear by making the rear half of the bottom wall 3 bulge upwards. 4 is formed.

Casters 5 are provided at both left and right ends of the front part of the bottom wall 3 of the refrigerator body 1. Reference numeral 6 designates a base plate which is elongated from side to side, and an intake port 7 with a mesh attached thereto is formed at its right end, an exhaust port 8 with a mesh attached is formed at its left end, and an exhaust port 7 is formed at its left end. An evaporating dish portion 9 as a steam dish is drawn adjacent to the evaporating dish 8, and an evaporating dish 10 is drawn adjacent to and in communication with the evaporating dish 9. The base plate 6 is disposed in the lower open part of the machine room 4 so as to close the open part. 11
3 is a refrigeration cycle compressor, which is attached to the base plate 6 above the evaporating dish portion 10 via a plurality of support springs 11a, as shown in FIG.

12 is a refrigeration cycle condenser, which is the fourth condenser.
As shown in the figure, the capacitor wire 12b is constructed by incorporating a single capacitor wire 12b in a meandering manner into a large number of fins 12a arranged in parallel, and the width dimension L thereof is set to be relatively small.

The capacitor 12 is attached to the right side of the base plate 6 so that the direction in which the fins 12a are arranged in parallel is in the front-rear direction. 13, the compressor 11 is mounted on one plate 6;
The fan motor 13a is located between the capacitor 12 and the capacitor 12, and its fan 13a faces the capacitor 12.

Reference numeral 14 denotes a partition plate that partitions the machine room 4 into left and right sides, and a communication port 14a corresponding to the fan 13a is formed in the center of the partition plate.

Reference numeral 15 designates a cover disposed on the rear open portion of the machine room 4 so as to close it, and reference numeral 16 designates casters provided at both left and right ends of the base plate 6.

Thus, in the refrigerator main body 1, the back wall 17 is connected to the wall 18 of the kitchen or the like.
3 so as to be in close contact with the Next, the operation of this embodiment having the above configuration will be explained.

During the cooling operation, the compressor 11 and fan motor 13 of the refrigeration cycle are operated. When the compressor 11 of the refrigeration cycle is activated, the compressor 11 compresses the gas refrigerant, converts it into liquid refrigerant via the condenser 12, and sends this liquid refrigerant to the cooler in the refrigerator compartment 2 to evaporate it. However, the compressor 11 and the condenser 12 generate a large amount of heat when compressing and condensing the gaseous refrigerant, respectively. When the fan motor 13 is operated as described above, the fan motor 13 sucks outside air into the machine room 4 from the intake port 7 and moves it from the right side to the left side, as shown by the arrow 19. The condenser 12 and the compressor 11 are cooled by the air flowing from the right to the left in the machine room 4, that is, the cooling air. When the compressor 11 and fan motor 13 operate, they generate operating noise, but these operating noises are caused by a portion of the bottom wall 3 located in front of the capacitor 12, fan motor 13, and compressor 11. The front wall 20 of the barrel machine room 4 prevents the discharge to the front side as much as possible.
According to this embodiment, the machine compartment 4 is formed in the lower rear part of the refrigerator body 1 by making the rear half of the bottom wall 3 bulge upward, and the base plate is installed in the open lower part of the machine compartment 4. A compressor 11 and a fan motor 13 are mounted on the base plate 6, and the evaporator plates 9 and 10 are drawn and formed on the base plate 6.
Since the capacitors 12 are arranged in a row from side to side, there is no need to form a chamber for storing the capacitors 12 in the lower front side of the bottom wall 3, which is different from the conventional case, and the internal volume of the refrigerator compartment 2 is reduced accordingly. Moreover, the operating noise of the compressor 11 and fan motor 13 is prevented from being emitted to the front side by the front wall 20 of the machine room 4, which is a part of the bottom wall 3. Therefore, the noise can be reduced.

In the above embodiment, the evaporation pans 9 and 10 are formed on the base plate 6 by drawing, but a separate evaporation pan may be provided on the base plate 6 instead. As described above, the present invention has advantages such as being able to increase the internal volume of the storage chamber, and furthermore, being able to minimize the operating noise of the compressor and fan motor, thereby reducing noise. It is possible to provide a refrigerator that has the following effects.
