有していた。However, in the configuration of the conventional example as described above, the heat generation amount is increased due to the large load of the compressor accompanying the enlargement of the refrigerator, and the heat radiation amount is greatly reduced due to the deterioration of the refrigerator installation gap. In recent years, the tendency toward a high temperature atmosphere in the vicinity of the compressor in the machine room has been particularly remarkable. The dryer is heated by the high temperature atmosphere in the machine room, which reduces the degree of supercooling and moves the refrigerant bubbling point in the capillary tube to the upstream side to reduce the cooling capacity due to the reduction of the refrigerant circulation amount and generate flash gas. There is a problem in that the cooling performance and reliability of the refrigerator are significantly reduced by inducing heat.

Fig. 1 shows the components installed in the
The configuration is the same as that of. The difference from the configuration of FIG. 1 is that the dryer 7 has a plate portion a10a that is heated by the condenser 6 of the cooling system to evaporate defrost water and a water level higher than that of the plate portion a10a that is not heated by the condenser 6. This is the point of contact with the defrosting water in the dish b10b of the evaporation dish 10 provided in the machine chamber 1 and made up of the dish b10b capable of storing a defrosting water in a fixed amount.
