<P>PROBLEM TO BE SOLVED: To provide a power supply device, capable of safely and surely feeding power to an electrical apparatus installed in a specified room, without using insulating means. <P>SOLUTION: The power supply device 1 feeds power to an actuator 31 of an automatic waste plug 3 that automatically opens and closes a sink outlet of a bathtub body 26a installed in a system bath 2, and comprises a contactless power transport means 10 that is composed of a power-transmitting part 11 that outputs a power transport wave and a power-receiving part 12 that receives the power transport wave outputted from the power transmission part 11, and conducts transfer of power by electromagnetic wave coupling. The power-transmitting part 11 is built in a wall panel 21 constituting the system bath 2, and the power-receiving part 12 is installed on the surface of the bathroom side inside the wall panel 21. The power transmitting part 11 and the power-receiving part 12 are arranged in a position, where they oppose each other with the wall panel 21 inbetween a region covered by a bathtub unit 26 inside the wall panel 21. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
