Abstract
PURPOSE: To selectively detect and display the temperatures of the parts to be temperature- detected by providing temperature detecting circuits for the plural parts to be temperature-detected, reference signal generating circuits for various temperatures via multiplexers and comparators.
CONSTITUTION: Reference signal generating circuits 13, 14 apply reference voltages as temperature reference signals to the respective channels of multiplexers 18, 19. Comparators 15, 16 compare the temperature detecting signals of thermistors 4, 8 corresponding to the temperatures in a refrigerating chamber and a freezing chamber and the reference signal voltages of the respective channels of the multiplexers 18, 19 and emit a coincidence signal and send the same to the input part 33 of an arithmetic unit 32 when these coincide. A temperature selecting circuit 20 sends the selection signals for displaying the temperature in the refrigerating chamber and freezing chamber to the abovementioned input part 33. The selection signal generating part 34 of the arithmetic unit 32 applies the channel selection signals to the multiplexers 18, 19 based on the abovementioned selection signals. The multiplexers in turn send the reference signals of the channels selected thereby to the comparators 15, 16. The arithmetic unit 32 emits the temperature signals and displays the temperature in a display device 37 through a driving circuit 36.
