Plural temperature adjustment apparatus for refrigerator

摘要

The present invention relates to a plural temperature adjustment apparatus for a refrigerator whereby adequate cooling grades are automatically changed based on the temperature changes inside a refrigerator and driving time, and more particularly to a plural temperature adjustment apparatus for a refrigerator whereby prolonged of life time of a compressor, reduction of electric power consumption by way of the control of frequent intermittency of a compressor and the effect of temperature adjustment by timer operation even during blackout can be achieved by adequate control of the present temperatures in a refrigerator detected by a temperature detecting part and appropriate control of compressor drivings based on door open/close status detected at a door open/close detecting part and driving time by a timer when temperatures and driving time according to respective cooling grades randomly set up by the user thru the operation part are inputted into a micro computer.
