When the human body is detected, the control unit 111 determines whether there is a counted human body non-detection time (S419), and initializes the counted human body non-detection time (S421), and then supplies heating power to the heating wire to start heating. (S423).

When the heating is started, the control unit 111 counts the human body detection time (S425), and checks whether the counted human body detection time exceeds a predetermined time (S427).

If the human body detection time exceeds a predetermined time, the control unit 111 determines whether it is a sleeping mode or a sleeping time zone (S429). When determining the sleep time zone, the switch unit 113 should be configured to input the sleep time zone, and the input sleep time zone should be stored in the storage unit 112.

If the sleep mode or the sleep time is not the control unit 111 by turning on the auxiliary human cognitive sensor 121 through the sensor driver 115 (S431), it is checked whether the human body is detected by the auxiliary human cognitive sensor 121. (S433).

At this time, if the human body is not detected, the control unit 111 controls the power supply unit 116 to cut off the heating power supplied to the heating wire to turn off the heating (S241).

If the human body is not detected by the human body sensor 120 during the heating (S435), the control unit 111 checks whether there is a counted human body detection time (S436), and if there is a counted human body detection time, the human body detection time. After the initialization (S437), the human body non-detection time is counted (S439).

The control unit 111 checks whether the counted undetected time exceeds a predetermined time (S441), and when the undetected human body time exceeds a predetermined time, cuts off the heating power provided to the heating wire to turn off the heating (S241). .
