To provide a freezing refrigerator that prevents the frosting of a freezing compartment, at the same time, to reduce the number of times of defrosting, and to save energy by providing a vent hole for connecting the freezing compartment to a cold room in a partition body, and by providing a valve disk for regulating the direction of air flow from the side of the freezing compartment only to the cold room due to pneumatic pressure in the vent hole.

In a refrigerator that is provided with a heat-insulating box body consisting of outer and inner boxes and a heat insulator that is filled between the boxes, a partition body 5 that is arranged in the heat-insulating box body and divides a cold room 6 and a freezing compartment 7 into upper and lower stages, a cold-room evaporator being provided on the outer surface of the inner box of the cold room 6, and a freezing-compartment evaporator being provided on an inner surface at the side of the freezing compartment 7 of the partition body 5, and cools the inside of the inner box by a natural convection current of chilled air being heat-exchanged in the evaporators, a vent hole 15 for connecting the freezing compartment 7 to the cold room 6 is provided in the partition body 5, and a valve disk 16 for regulating the direction of air flow from the side of the freezing compartment 7 only to the cold room 6 by pneumatic pressure is provided in the vent hole 15.
