Abstract

PURPOSE: To obtain a temperature controller for heating bedclothes providing a good sense of use, by equipping a means of alternating a variable desired-temperature setting means and invariable prescribed-temperature setting means, a self- holding means of short-circuiting temperature setting means, and a hold releasing means.
CONSTITUTION: The main circuit consists of AC power source 1, heating filament 4, switching element 2, and switch 3x, and the temperature detecting means of heat- sensitive body primary winding 7, heat-sensitive layer 8, the secondary winding 9, and resistances 26 and 27. With change-over switch 3y placed at side 9, capacitor 39 is discharged at positive half cycles to turn on element 2, and consequently heating filament 4 is fed with electric power to give a rise in temperature. In this case, LED16 turns on to indicate a self-holding state and transistor TR25 conducts to short-circuit resistance 32, setting the temperature to its maximum temperature. At the maximum temperature, heat-sensitive layer 8 decreases in impedance and TR25 turns off to release the self-holding, so that the temperature drops to a temperature, set by resistance 32, adequate for sleeping. With switch 3y set to side (b), a random temperature is set by variable resistance 33.
