An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a refrigerator main body in which a freezer compartment 2 and a refrigerator compartment 3 are arranged above and below, and a shelf-shaped cooling plate 4 for direct cooling is installed in the center of the freezer compartment 2 in a substantially horizontal state. A second cooler 5 for indirect cooling is installed in the section. Reference numeral 6 denotes a partition wall that separates the second cooler 5 and the inside of the freezer compartment 2, which forms a cold air passage 7 and forces the air into the freezer compartment 2 through the cold air passage 7 and the second cooler 5. A fan 8 for generating circulating air is provided at the outlet end of the cold air passage 7. Reference numerals 9 and 10 are an inlet and an outlet that communicate with the cold air passage 7 to cool the inside of the refrigerator compartment 3. In detail, regarding the cooling plate 4, reference numeral 11 denotes a refrigerant pipe of the first cooler 12, which is surrounded by a heat insulator 13 as a heat insulating member within the flat box-shaped cooling plate 4. The heat insulator 13 is interposed between the cooling plate 4 and the refrigerant pipe 11 to prevent the refrigerant pipe 11 from directly contacting the cooling plate 4. The refrigerant pipe 11 of the first cooler 12 and the refrigerant flow path of the second cooler 5 are connected in series as shown in FIG. 2. Further, in the refrigerant circuit diagram shown in FIG. 2, 14 is a compressor, 15 is a condenser, and 16 is a capillary reach tube.

ことを防止できる。 Next, the operation of the above configuration will be explained. When the compressor 14 is operated, the fan 8 is simultaneously driven to rotate. Then, the gas refrigerant compressed by the compressor 14 is liquefied in the condenser 15 and evaporated in the refrigerant pipe 11 of the first cooler 12 and the second cooler 5, but in this case, the refrigerant pipe 11 The pressure inside and the inside of the second cooler 5 are equal, and the evaporation temperatures are the same. However, the first cooler 1
Since the heat insulator 13 is interposed between the second refrigerant pipe 11 and the cooling plate 4, the surface temperature of the cooling plate 4 is higher than that of the second refrigerant pipe. The temperature becomes higher than the surface temperature of the cooler 5, so frost is concentrated on the second cooler 5, and frost is formed on the surface of the cooling plate 4 surrounding the first cooler 12 for direct cooling. Instead, it is only necessary to defrost the second cooler 5. Therefore, the frozen food placed on the cooling plate 4 can be prevented from thawing during defrosting.

Alternatively, the second cooler 5 may be of a direct cooling type.

As is clear from the embodiments described above, the present invention connects the refrigerant pipes of the first cooler and the refrigerant flow path of the second cooler, and connects the refrigerant pipes of the first cooler to the cooling plate. Since a heat insulating member is interposed between the two coolers, the surface temperature of the cooling plate can be made higher than the surface temperature of the second cooler without reducing operating efficiency, making it possible to form concentrated frost on the second cooler. We can provide you with a refrigerator.
