Title:
REFRIGERATOR TEMPERATURE CONTROL DEVICE OF COOLING REFRIGERATOR
Document Type and Number:
Japanese Patent JP3190793
Kind Code:
B2
Abstract:
PURPOSE: To provide a refrigerator temperature control device of a cooling refrigerator in which a refrigerator temperature can be controlled to be constant in response to its set temperature under a flexible accommodation for a surrounding air temperature.
CONSTITUTION: A first sensing temperature is set to a refrigerator thermostat Th1 through a rotating shaft, a volume and a connecting wire in response to a rotation of a knob in reference to a temperature display at a setting panel of a temperature setting device, and a second sensing temperature which is the same as or slightly lower than the first sensing temperature through the rotating shaft, the volume and the connecting wire in cooperation with a setting of the first setting temperature. In addition, in the case that an outside thermostat Th3 of the refrigerator is turned on in response to the fact that the surrounding air temperature is lower than the refrigerator temperature, a drain pan heater H2 is heated and driven to keep the refrigerator temperature constant in response to the turned-on or turned-off state of the refrigerator thermostat Th1.
