Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement structure of a refrigeration mechanism in a refrigerator or the like in which a base plate on which a refrigeration mechanism is arranged can be freely put in and taken out of a machine room.

[0002]

2. Description of the Related Art Vegetables, fruits and other fresh foods such as meat and fish (hereinafter referred to as "ingredients") are stored as a refrigerator or a freezer (hereinafter referred to simply as "refrigerator") for a long period of time, for example, as shown in FIG.
As shown in FIG. 2, a horizontal refrigerator having a horizontally long cabinet is known. Inside the horizontally long box-shaped main body (cabinet) 10, a storage box 12 for cooling and storing foodstuffs and a machine room 14 adjacent to the storage box 12 with a wall between them are defined. Has been done. As shown in FIG. 13, a pair of guide rails 16 and 16 are arranged in parallel at a predetermined distance in the width direction on the inner bottom of the machine chamber 14, and a base plate 18 is arranged between the rails 16 and 16 in the front and rear direction. It is arranged so that it can slide in any direction. A refrigeration mechanism 22 including a condenser 20, a cooling fan, a compressor (all not shown), and the like is arranged on the base plate 18, and the refrigeration mechanism 2 is installed in the machine chamber 12.
By constructing the unit 2 and the base plate 18 so that they can be taken in and out integrally, the assembly and maintenance of the refrigeration mechanism 22 are facilitated.

As the condenser 20, a fin-and-tube type is generally used, and a cooling fan disposed between the condenser 20 and the compressor is operated to forcibly generate heat in the condenser 20 and the compressor. Air cooling is performed. In the refrigerator including the air-cooled condenser 20, an air suction port and a discharge port are opened in the machine room 14, and the air sucked from the suction port by the rotation of the cooling fan contacts the condenser 20. After cooling by heat exchange, the air whose temperature has risen is discharged to the outside through the discharge port. In this case, dust is also sucked into the machine room together with the air, but if this dust adheres to the condenser 20, it not only becomes a kind of heat insulating layer, but also becomes ventilation resistance and reduces heat exchange efficiency. It may cause failure due to high pressure rise. Therefore, a filter for collecting dust is arranged at an appropriate position on the air suction side of the condenser 20, and the air purified by the filter is brought into contact with the condenser 20.

[0004]

As described above, it is necessary to provide a filter on the air suction side of the condenser 20 for cleaning the air. However, the mesh of the filter is made fine and fine. If dust is to be collected, the air itself may not flow smoothly, and the condenser 20 may not be sufficiently cooled by air. Therefore, the mesh of the filter cannot be made very fine, and it is inevitable that fine dust passes through the filter and adheres to the front surface of the condenser 20. Therefore, the dust adhering to the front surface of the condenser 20 is regularly brushed off by a brush or the like. The dropped dust scatters on the inner bottom portion of the machine chamber 14 and a wide range of the base plate 18,
Cleaning this was complicated. Further, since the cooling fan is controlled to be turned on and off, the dust adsorbed on the filter under the suction action of the cooling fan falls when the fan is stopped and falls on the inner bottom portion of the machine chamber 14 or the base plate 18. It was also troublesome to clean it because it got dirty.

The base plate 18 which is arranged so as to be able to be taken in and out of the machine room 14 is adapted to be screwed and fixed in the vicinity of both end portions in the width direction on the front side while being housed inside the machine room 14. That is, as shown in FIG. 13, the screws 24 for fixing the base plate 18 in the machine room 14 are
Since it is close to the frame body 26 that defines the number 4, the internal width dimension of the machine room 14 with respect to the width dimension of the base plate 18 must be set with a sufficient margin when the base plate 18 is assembled in the manufacturing line, repaired, or repaired. For maintenance such as cleaning, the base plate 18
It becomes difficult to handle tools such as a screwdriver when removing. However, if the internal width of the machine room 14 is increased, the internal volume of the storage case 12 is reduced in proportion to this. Therefore, if the width dimension of the refrigerator is increased to secure the internal volume of the storage 12, there is a problem that the refrigerator itself becomes large.

[0006] A pair of guide rails 16, which guide the loading and unloading of the base plate 18 and also serve as positioning in the width direction,
As shown in FIG. 13, 16 is set to guide and position both widthwise outer side surfaces of the base plate 18. Therefore, it is necessary to increase the internal width dimension of the machine room 14 by the dimension for disposing the guide rails 16 and 16. As described above, there is a problem that the internal volume of the storage 12 becomes small and the refrigerator becomes large. is there. In addition, the positioning of the rear portion of the base plate 18 in the vertical direction is performed by placing the base plate 1 at the rear of the machine room
An overhanging member that horizontally extends forward is disposed at a level substantially the same as the height dimension of 8, and the base plate 1 is provided below the overhanging member.
It was done by facing the rear part of 8. However, since this overhang member has a structure in which another member is attached to the frame 26 of the machine room 14 by welding or the like, the number of parts is increased and the cost is increased.

Since there is no place on the outer periphery of the conventional base plate 18 where an operator's fingers are caught, when the base plate 18 having the refrigerating mechanism 22 is assembled in the machine room 14, When the base plate 18 is placed on a flat table, a base, or the like, it is the current situation that the base plate 18 is lifted while holding a component such as a compressor arranged on the base plate 18. For this reason, it is pointed out that the location where the component and the base plate 18 are disposed becomes loose or comes off. A handle for easily removing the base plate 18 from the machine room 14 may be fixed to the front surface of the base plate 18 with a screw, and the handle may be used to lift the base plate 18. Since it is a member different from 18, the number of parts and the number of assembling steps increase.

Management is also easy.

[0022]

As described above, according to the arrangement structure of the refrigerating mechanism in the refrigerator or the like according to the present invention, the dust falling from the condenser can be collected in the groove formed in the base plate, so that it can be dropped. The dust that has been collected can be easily cleaned. Since the base plate is fixed to the machine room by screwing the handle formed on the front surface of the base plate, it is easy to handle the tools when installing and removing the base plate, and the internal width of the machine room is reduced. The setting can be made short, and the internal volume of the storage can be expanded or the refrigerator can be downsized. Moreover, since the base plate and the handle are integrally formed, the number of parts does not increase, and the cost can be kept low.

Since the distance between the pair of guide rails arranged on the inner bottom of the machine room is set shorter than the width of the base plate, the inner width of the machine room can be set short. In addition, since the base plate can be easily lifted by the guide portion formed on the base plate, when assembling the refrigeration mechanism to the machine room, it is possible to avoid lifting the components constituting the refrigeration mechanism by holding them. Therefore, it is possible to prevent loosening or disengagement of parts where the parts and the base plate are arranged. Further, since the vertical positioning of the rear portion of the base plate is performed by inserting the positioning portion integrally formed in the rear portion of the base plate into the slit formed in the rear portion of the machine room, a separate member is used. Since it is not necessary to mount it on the machine room or the base plate, the number of parts can be reduced and the cost can be reduced.
