When power is applied to the vending machine configured as described above, the compressor 10 is operated and the evaporator 16 and the fan 17 for the evaporator are operated to absorb the heat from the high inside A, thereby circulating the cooling air in the direction of the arrow. While cooling is achieved, the condenser 8 and the condenser fan 9 are operated at the same time to discharge the heat absorbed by the evaporator 16 to the outside of the vending machine through the hot air outlet 1a.

However, in the conventional vending machine, when the refrigeration cycle is installed inside the vending machine, the connection part of the evaporator, the compressor, and the condenser is formed of a capillary tube, a suction pipe, and a pipe insulator, which are easily deformed, making assembly difficult and difficult to separate the refrigeration cycle. There was a problem of poor serviceability.

In addition, when the capillary tube, the suction pipe, the pipe insulator penetrating the heat insulating material is formed in the front portion of the heat insulating bottom there is a coupling that is less sealed when the door is closed, and the suction pipe is formed long, the piping in the refrigeration cycle configuration There was a problem that the damage is large.

An object of the present invention is to improve the assembly and serviceability can be easily assembled and separated by uniting the refrigeration cycle.

Another object of the present invention is to form a suction pipe penetrating part on the rear side of the insulating floor so as to be close to the evaporator and the compressor to maintain good sealing when the door is closed, and to simplify the piping configuration of the refrigeration cycle to minimize the pipe loss by efficient piping configuration I'm trying to.

In order to achieve the object of the present invention, it is connected integrally in a state separated from the machine room base seated on the bottom of the cabinet, the left and right side and the back is in close contact with the left and right and rear insulation wall and the front is assembled to be in close contact with the insulation door A refrigeration unit assembly structure of a vending machine is provided that includes a separate insulating floor, and the high pressure part is mounted on the insulating floor on the machine room base so that the high pressure part and the low pressure part are forcibly integrated by the insulating floor.

Hereinafter, the present invention as described above will be described in detail by the accompanying drawings.
