Abstract

PROBLEM TO BE SOLVED: To easily install a power supply in a bathroom of an already built house. SOLUTION: A power supply plug 1, which supplies a power in a noncontact manner, is fed with a power by a power supply line 20 which is drawn into a bathroom for a lighting appliance 2 already installed in the bathroom. Instead of directly feeding the power supply plug 1 with a voltage of AC 100 V, the AC 100 V is converted into, for instance, a DC 12 V or DC 24 V by a voltage conversion unit built in a power supply adaptor 3 placed in the draw-in part of the power supply line 20 and the DC output voltage is transmitted to the power supply plug 1 from a low voltage output terminal. In the power supply plug-socket 1, the DC voltage is converted into an AC voltage (preferably a high frequency AC voltage) by a built-in inverter and supplied to a primary coil for electromagnetic induction. The reason for the AC voltage being once converted into a DC voltage is that, although wires connected to the power supply plug 1 is covered with a molding, they become exposed wires and enhance improved safety.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to an example of an embodiment. In the example shown in FIG. 1, a power supply outlet 1 for performing non-contact power supply by electromagnetic induction is installed in an existing bathroom installed in a bathroom. Power is obtained from a power supply line 20 drawn into the bathroom for the lighting fixture 2 of FIG. However, in the illustrated example, the output converted to, for example, DC12V or DC24V by the voltage conversion unit 30 built in the power adapter 3 installed in the lead-in portion of the power line 20 is not sent directly to the power supply outlet 1 in the illustrated example. The power is supplied from the low-voltage output terminal 31 to the power supply outlet 1. The power supply outlet 1 is converted into AC (preferably high frequency) by a built-in inverter and supplied to a primary coil (not shown) for electromagnetic induction. The reason why the power supply is once converted to the DC low-voltage power supply is to increase the safety because the wiring 17 to the power supply outlet 1 is an exposed wiring although the molding 18 can be covered.

Here, it is assumed that the power supply adapter 3 is also provided with a low-voltage output terminal 32 for lighting equipment.
That is, the lighting fixture 2 can be changed from the existing one for AC 100 V to a more secure low-voltage power supply type. At this time, the low-voltage power supply type lighting fixture 2 is a waterproof type compatible with a wireless switch, and the existing lighting switch installed outside the bathroom is always turned on so that the lighting fixture 2 is not used. Power can be taken from the power supply outlet 1 as well.

The power adapter 3 may be disposed in the lighting fixture 2 including the fixture body 22 and the cover 23. A waterproof cable is used for the wiring 17 from the power adapter 3 to the power supply outlet 1. Lighting equipment 2
The lead-out portion of the wiring 17 and the lead-in portion of the wiring 17 of the power supply outlet 1 are waterproofed by using a packing 25 or a molding 18. The draw-in portion of the molding 18 is fixed by sandwiching it through the packing 25 when the base portion 11 and the cover portion 12 of the power supply outlet 1 are fixed. The reason why the lower end of the mall 18 is extended downward from the drawing portion to the power supply outlet 1 is to prevent water from dropping into the power supply outlet 1 by dripping water.

The power supply outlet 1 is preferably located near the floor of the washing area for ease of use. However, since this portion is often tiled, it is preferable to fix it with an adhesive or a suction cup.

FIGS. 6 and 7 show other examples. This is achieved by using an electric device 5 to be installed by drawing the power supply line 20 into the bathroom, in the illustrated example, a power supply outlet 1 for performing non-contact power supply by electromagnetic induction as a bath water purifying device. The power supply outlet 1 is also installed along with the installation of the electric device 5. 5 in the figure
0 is an insulating transformer. As such an electric device 5, a sauna device, a heater, a controller for a water heater, or the like can be used.

Another example is shown in FIG. The power supply outlet 1 is connected to a low-voltage power line 60 for an existing emergency push button switch 6 installed in a bathroom, and a low-voltage power supply supplied to the wireless push button switch 6 is provided. (DC12V or DC24V) is also supplied to the power supply outlet 1 with a built-in inverter.

In this case, as shown in FIG. 9, the push button switch 6 is once removed and the branch line 1 is connected to the low-voltage power supply line 60.
7 is connected, and the push button switch 6 is reattached via the mounting frame 62 which is a raised bottom, so that the lead-out portion of the branch line 17 is waterproofed together with the packing at the portion of the mounting frame 62.

When it is difficult to attach the push button switch 6 once removed from the wall surface to the wall surface again, as shown in FIG. This may be attached to the place where the original push button switch 6 was installed.
