Warm Water Washing Toilet Seat

Overview

Warm water washing toilet seats are hit products because they provide great comfort and important hygienic benefits. In Japan, sales of such toilet seats have increased every year, to the point where today approximately 70 percent of Japanese households have them. In addition, new products with greater functionality in addition to the basic functions of seat warming and warm water spray are appearing. Added features include warm-air drying, odor elimination, room heating, automatic toilet flushing, and automatic open/close. Some of the newer seat systems use a sensor to detect the presence of a person approaching and heat the seat instantly. Because a warm water washing toilet seats constantly consumes electricity, low power consumption is important for eco-friendliness and many models feature a low-power setting.

To support manufacturers provide consumers with a more comfortable living environment through such functions, Renesas Electronics supplies a wide range of microcontrollers well matched to the requirements of the seat systems and their remote-control devices. Excellent solutions abound in the 720 Family, 78K0R/Kx3-L, the M16C/60 Series, the M16C/30 Series, the R8C/2x Series, the R8C/3x Series and the R8C/Lx Series. We also supply other semiconductor devices used in these applications, including control TRIACs and power MOSFETs. These chips meet demands for advanced functionality, high-performance, reduced power consumption, and lower cost.
