SANITARY WASHING DEVICE

PURPOSE: To automatically correct an error in hot air temperature due to fluctuation of primary voltage, variation of resistance value of a heater or variation in rotating speed of a motor so as to supply hot air equal to a preset temperature. CONSTITUTION: A heater controlled variable is calculated from a difference between a preset temperature and room temperature and heat supply capacity of a drying unit 1 by CPU 11, and the heater controlled variable is corrected according to the rotating speed of a motor 1a detected by a motor rotating speed detecting part 12, the resistance value of a heater 1b based on the current value of the heater 1b detected by a heater current value detecting part 13, and the primary voltage value of a commercial power supply 4 detected by a primary voltage detecting part 14. According to the corrected heater controlled variable, the drive control for the heater 1b is directed to a drying heater driving part 8.
