PURPOSE:To obtain both cold and hot storage functions with a simple construction, by providing an exothermic body in parallel to a refrigerating evaporator with respect to air stream blown by a blower and as well by providing a damper for switching between air passages to the refrigerating evaporator and to the exothermic body. CONSTITUTION:A door 2 for closing a top opening of an insulating structure box 1, is closably attached by means of a hinge 3, air-intake grilles 11 are secured to stepped parts 1a through 1b formedin the bottom of the box 1, and a cold blast passage 27 is formed. An evaporator 108 consisting of a freezing evaporator section 108a for cooling a freeze storage chamber 110 and a refrigerating evaporator section 108b communicating with a cold storage chamber 111, is disposed in a casing 15 having an opening part 15a closed by a cold storage box door 16 and encased in the box 1. Further, an exothermic body 114 is disposed in an air passage 117 arranged in parallel with a blast passage to the evaporator part 108b, thereby blast by a blower 112 is selectively made to the exothermic body 114 or the evaporator 108 by switching a damper 111. |
