PURPOSE:To exercise control suitable to a user by providing a controller which has an oscillator for controlling a heating body at a distance and a receiver which controls the heating body by receiving a signal from the controller. CONSTITUTION:An electric blanket, or the like is provided with a controller which has an oscillator for controlling a heating body remotely without being connected to a heating body 2. The controller 6 consists an oscillating circuit 14 of a transistor 7, oscillation coils 8, electrodes 9 at both their ends, a power source 10, and a band 11. When a user wears the band 11 on his or her arm, etc., to bring the electrodes 9 into contact with the skin, oscillations continue because the skin resistance is initially high, and then the heating body keeps on generating heat. As the user feels warm, the skin resistance decreases, so the oscillations of the controller 6 stop, and the output of the receiver 12 is stopped correspondingly, so that a controller 3 controls the generation of heat of the heating body 2. Thus, the control over the heating body corresponds to the feeling of the user automatically. |
