Title:
TOILET DEVICE
Document Type and Number:
Japanese Patent JP2014134004
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a toilet device that can have specifications made common even when differing in power supply voltage and also suppress upsizing and rise in costs accompanying the commonalization.SOLUTION: There is provided a toilet device including: a plurality of heaters; a rectification part which rectifies a current supplied from a power supply; a step-down part which steps down the rectification output of the rectification part by turning ON/OFF step-down switching elements, and supplies the stepped-down output to the plurality of heaters; a plurality of switching elements for heater which are provided between the step-down part and the plurality of heaters respectively; voltage detection means for detecting the voltage of the power supply; and a control part which controls the electric power supplied to the plurality of heaters. The control part controls at least one of the duty ratio and frequency of the step-down switching element according to the electric power that the plurality of heaters require and the voltage of power supply detected by the voltage detection means so that the supply voltage to the plurality of heaters have a predetermined value or less.
