The electric refrigerator 30 shown in FIG. 6 divides the inside of the heat insulating box 31 up and down by a partition wall, and has a refrigerator compartment 32 at the top, a vegetable compartment 33 at the center, and a freezer 34 at the bottom. Cold air in the refrigerator compartment 32 is supplied into the vegetable compartment 33 through a cool air passage 39, the internal temperature of which is maintained in a range of about 2 ° C to 8 ° C. Cold air from the evaporator is directly supplied to the inside of the tube 34 so that its internal temperature is cooled to about -15 ° C to -22 ° C. The vegetable compartment 33 and the freezing compartment 34
Is separated by a partition wall 35 enclosing a heat insulating material, but since there is a difference in temperature between the two at 20 to 30 ° C., it is difficult to perform complete heat insulation.
May be adversely affected by the cold air in the freezing room 34, which is excessively cooled by the cold air in the freezing compartment 34 and has a negative effect on the stored vegetables and the like. In order to prevent this, a warming heater 36 is provided on the bottom surface of the vegetable room 33, and when there is a possibility that the inside of the vegetable room 33 will be in a supercooled state, the warming heater 36 is energized. The inside of the vegetable compartment 33 is heated by the heat generation to keep the temperature in an appropriate temperature range.
