ICE STORAGE DETECTING MEANS FOR AUTOMATIC ICE-MAKER

摘要

PROBLEM TO BE SOLVED: To control three or more ice manufacturing units with one storage-of-ice switch. SOLUTION: In the condition that three ice-maker units 18 are piled, three storage-of-ice control circuits 60 are connected in parallel with the storage-of-ice switch SW1, and a diode D connected between a direct current power source DC of each storage-of-ice control circuit 60 and the storage-of-ice switch SW1is connected in a direction for hindering flow of the current from the direct current power source DC of other storage-of-ice control circuits 60 to a microcomputer PC. An alternating current power source AC is connected to the direct current power source DC of each storage-of-ice control circuit 60 through a leak breaker 20 so that the alternating current is converted to the predetermined direct current voltage through an alternating current-direct current converter.
