Title: Heating device for toilet
Inventor: KOMACHI HIROSHI
IPC: A47K17/00
Filed: 1988-04-22
Abstract: PURPOSE:To prevent the reduction degradation of a positive characteristic thermistor element and the lowering of a heating feeling by providing an air blower, which generate air flow to go toward the inside of a toilet, and the positive characteristic thermistor element to heat air in an external air conducting-type blasting duct. CONSTITUTION:A PTC heater 43 is formed by arranging a lot of positive characteristic thermistor elements 47 between a positive electrode board 47 and a negative electrode board 49. When a user is seated on a toilet seat 24a, a turn-on signal is outputted to a shaft flow fan 42 and the PTC heater 43. The fan 42 is revolves and sucks the external air, which exists in an outside 21 of a toilet 2, from an external air conducting port 31b to a blasting duct 3. The external air flows into a chamber 32 and the kind of dust, etc., is absorbed by a filter 32a. The external air flows through a duct 33 into a hot wind duct 34 and blown to an inside 25. Here, since the Curie point of the heater 43 is set to be lower than the ignition point of a foreign object such as the dust, etc., to exists in the external air, the heater is heated with consuming a large current when a temperature is low. Then, when the temperature goes over the Curie point, the consumption of the current is suppressed and a constant surface temperature is maintained.
