And an evaporator 16 connected to the
And a suction tube 16a, a capillary tube 16b, and a heat insulating tube 16 covering them through a through hole 13b provided on one surface of the cooling and heat insulating box 13 and arranged in the machine room 8.
c, while the evaporator 16
Is a defrosting heater 17 tightly fixed and a drain guide 1
8 and a drain pan 19 having a drain port 19a at the bottom and a drain pan heater 19b tightly fixed thereto are arranged to form a cooling chamber 20. A cooling fan 21 disposed on the side of the storage room 2 above the side opening 14; a cooling chamber cover 22 provided with a discharge port 22a and a suction port 22b adjacent to the cooling fan 21; A louver 23 is provided on the chamber 2 side. Further, a ceiling plate 24 is disposed on the ceiling of the storage room 2 and the cooling and heat insulating box 13, and the storage room 2 of the machine room 8 is provided.
A side plate 25 is arranged on the side surface facing the side, and a machine room bottom plate 26 is arranged on the bottom of the machine room 8. FIG. 13 is an enlarged view of a main part of the cooling and heat insulating box 13. The through-hole 13a is connected to the defrost heater 17, the drain pan heater 19b, and the lead wires 17a, 19c, 21a of the cooling fan 21 together with the suction assembly 16d. After that, it is sealed with a sealing material 27 and connected to a control box 28 installed above the machine room. FIG. 14 shows a state in which the unit base 9 is drawn forward together with the cooling and heat insulating box 13. The operation of the horizontal refrigerator configured as described above will be described below.

[0005] First, the refrigerant compressed by the compressor 10 is condensed by the condenser 11 and the condenser fan 12, then the pressure is reduced by the capillary tube 16b and evaporated by the evaporator 16, and then the suction pipe 16a Through the compressor 10
The evaporator 16 is cooled by the cooling action of returning to the storage chamber 2, and after cooling air is sent from the discharge port 22 a into the storage chamber 2 by the cooling fan 21, the operation of returning to the evaporator 16 from the suction port 22 b is repeated. Is cooled. Further, by the above-described cooling action, the frost adhering to the evaporator 16 is melted by the heat generated by the defrost heater 17, falls into the drain pan 19, and is discharged from the drain port 19a. Also, the compressor 10,
Repair and replacement of the inside of the machine room 8 such as the condenser 11 are performed after the unit base 9 is pulled out forward. Further, the evaporator 16
As shown in FIG. 13, the screw 15 of the metal fixing member 13 a fixing the cooling and heat insulating box 13 is removed, and the cooling and heat insulating box is separated from the side opening 14 and then pulled out together with the unit base 9. After that.

[0006]

However, in the above-mentioned conventional structure, when the back of the machine room is closely contacted with a wall or the like, heat generated by the compressor 10, the condenser 11, and the condenser fan 12 at the time of a cooling action is generated. The temperature inside the machine room 8 rises, the machine room 8 becomes narrower because the upper part of the machine room 8 is occupied by the cooling and heat insulating box 13 arranged above the machine room 8, and heat escapes to the back of the machine room 8. Because of the absence, the inside of the machine room 8 easily rises, and the temperature inside the machine room 8 rises, which may hinder the start and operation of the compressor 10, and also shorten the life of the compressor 10 and the condenser fan 12. , A compressor 10 and a condenser 1
1, when the condenser fan 12 is repaired or replaced, when the unit base 9 is pulled out, the suction pipe 16a and the like
When the evaporator 16 is repaired or replaced, the cooling and heat insulating box 13 cannot be pulled out because the length of the suction pipe 16a is not enough. It is difficult to draw out only the cooling and heat insulating box 13 having substantially the same width, and it is necessary to place the cooling and heat insulating box 13 on the condenser 11 and pull out the entire unit base. There was a disadvantage that it took time.

The width of the condenser 11 must be larger than the diameter of the condenser fan 12, so that the size of the machine room 8 is inevitably increased.
a) When the unit base 9 is pulled out because the lead pipe 11a of the condenser 11 is piped outside the condenser 11, the discharge pipe 10a and the like hit the machine room side plate 25 and the like, and there was a defect that it was damaged.

Further, it is necessary to securely seal the through hole 13a of the cooling and heat insulating box 13 so as not to leak the cool air from the cooling chamber, and the lead wire 17a of the suction assembly 16d and the defrost heater 17 and the like pass through the clay. The sealing with the seal member 27 is uncertain due to the movement of the lead wire 17a such as the suction assembly 16d and the defrost heater 17 during the sealing operation. However, there is a disadvantage that dew condensation occurs on the surface of the sealing material 27 due to the heat conduction.

The present invention solves the conventional problems.
It keeps the temperature rise in the machine room low so that the start and operation of the compressor can be performed without any trouble, and the life of the compressor and condenser fan can be extended, and the compressor, condenser and condenser fan can be easily replaced and repaired. You can pull out the unit base,
It can be easily pulled out when the evaporator is repaired or replaced,
The purpose is to simplify the repair and replacement work of the unit.

It is an object of the present invention to make the width of the machine room as small as possible and to easily pull out the unit base without the discharge pipe and the condenser lead pipe coming into contact with the machine room side plate.

It is another object of the present invention to surely seal the through hole of the cooling and heat insulating box and eliminate dew condensation on the surface of the sealing material.

[0012]

In order to solve this problem, a horizontal refrigerator according to the present invention is provided side by side with a heat insulating box, and has a machine room provided with a compressor, a condenser, and a condenser fan at a lower part thereof. An evaporator installed on the inside of the side of the heat insulation box, a suction storage part where a part of the side of the heat insulation box is cut out, and a suction storage part from the evaporator, extend to the machine room, and extend above the compressor. It has a suction assembly formed in a loop.

[0013] Thus, the temperature rise in the machine room is kept low, and the start and operation of the compressor can be performed without any trouble.
The service life of the condenser fan is extended, and the unit base can be easily pulled out for repair and replacement of machine room parts such as the compressor.Also, the unit can be easily removed for repair and replacement of the evaporator. Repair and replacement work can be simplified.

A compressor, a condenser, and a condenser fan are arranged below the machine room juxtaposed with the heat insulating box, and are arranged between the condenser and the condenser fan motor. And a fan ring having a flange portion protruding from the fan ring.

Thus, the width of the machine room can be reduced as much as possible, and the unit base 9 can be easily pulled out without the discharge pipe and the condenser lead pipe coming into contact with the machine room side plate.

Further, a suction storage portion in which a part of the side surface of the heat insulating box is cut off in a semicircular shape, a suction assembly extending from the evaporator through the suction storage portion to the machine room, and a suction assembly covering the suction storage portion. The product side is formed in a semicircular shape, and a side cover that defines the side surface of the heat insulating box is provided.
