PURPOSE:To provide an electric refrigerator which can keep a specified temperature even when foodstuffs are irregularly disposed in a refrigeration chamber. CONSTITUTION:A refrigeration chamber 1, refrigeration chamber 2, vegetable chamber 3, evaporator 4 for generating cold air, and a cold air duct 7 for leading cold air to the chambers 2 and 3 are provided. And a sensor 9 for detecting inside temperature and a device 10 for opening and closing an opening of the duct 7 are provided. The device 10 is controlled by a microcomputer. The microcomputer memorizes the open-close intervals of the device 10 and inside temperatures in a no load operation. When the inside temperature rises due to opening and closing of a door and when said intermals of the device 10 are smaller than an interval which has been set, the microcomputer lowers temporarily the set value of inside temperature to make longer the release time of the device 10 thereby making the open and close interval equal to that of the no load operation. |
