PURPOSE:To increase heat capacity, and to improve comfortableness by a method wherein a blast from a blower incorporating a heater is forwarded into a mat, blown out from the surface of the mat and sent continuously up to a set temperature and operation and suspension are repeated. CONSTITUTION:When a heating switch 24 is closed, the heater 7 is conducted, a delay circuit is operated, the blower 6 is turned while being delayed by time set, and hot air having a predetermined temperature is forwarded into the mat 2 until the inside of the mat 2 reaches the predetermined temperature. In this case, the heater 7 is controlled by means of an air-temperature sensor 15, and the temperature of air is kept constant. The hot air to the mat 2 ventilates the surface of the mat 2, and is blown off. When a temperature 14 in the mat 2 reaches a temperature set, conduction to the heater 7 and the operation and suspension of the blower 6 are repeated at a period set. According to such constitution, heat capacity can be increased, and comfortableness of the user can be improved. |
