  The output control circuit 11 supplies a certain weak current from each AC power supply device 9 to each primary coil 3 in a standby state in which the ultraviolet LED 5 is not lit. When the lids 2L and 2R are put on the bathtub 1, the impedance changes as the secondary coils 6 of the lids 2L and 2R approach the primary coils 3, respectively. Each monitor circuit 10 determines whether or not the lids 2L and 2R are covering the bathtub 1 in a normal posture by monitoring the current change accompanying the change in impedance.

  The lids 2L and 2R are put on the bathtub 1 in a normal posture, the secondary coil 6 of the lid 2L faces the primary coil 3 for the lid 2L, and the secondary coil 6 of the lid 2R is opposed to the primary coil 3 for the lid 2R. When facing each other, each monitor circuit 10 detects a predetermined impedance value. In this case, each monitor circuit 10 determines that the lids 2 </ b> L and 2 </ b> R are placed on the bathtub 1 in the normal posture, and issues an LED lighting signal to the output control circuit 11. In response to this signal, the output control circuit 11 increases the current from each AC power supply device 9 to an output value necessary for lighting the ultraviolet LED 5.

  As a result, an induction current flows through each secondary coil 6 by electromagnetic induction, and each ultraviolet LED 5 is turned on.

  In this embodiment, even if the lids 2L and 2R are placed on the bathtub 1, the ultraviolet LEDs 5 are not turned on unless each monitor circuit 10 detects a predetermined impedance value.

As shown in the drawing, the flange 52a protrudes sideways in a flush manner with the surface from a position retracted from the back surface of the lid 52 (the surface facing the back side of the apron 50) to the front surface side. A concave step portion 51a with which the flange 52a is engaged is formed at the peripheral edge portion of the opening 51.

  In attaching the lid 52, the lid 52 is fitted into the opening 51 from inside the bathroom. At this time, the flange 52 a engages with the peripheral edge portion (concave step portion 51 a) of the opening 51. Next, the flange 52 a is screwed (not shown) to the periphery of the opening 51.

  A primary coil 53 is provided so as to go around the opening 51, and a secondary coil 54 is provided so as to go around the periphery of the lid 52. An alternating current is supplied to the primary coil 53 from an alternating current power supply device (not shown).

  In this embodiment, the back side of the lid 52 is turned on by the induced current generated in the secondary coil 54 and ultraviolet rays are directed toward the back side space of the opening 51 (the space between the apron 50 and the side surface of the bathtub 1). An ultraviolet LED 55 to be irradiated is attached.

  In this embodiment, when the lid 52 is attached to the opening 51, the secondary coil 54 faces the primary coil 53, an induced current is generated in the secondary coil 54, and each ultraviolet LED 55 is lit by this induced current. . As a result, ultraviolet light is irradiated to the back side space of the opening 51, and ultraviolet sterilization and decomposition of attached organic matter are performed. In addition, you may provide the photocatalyst layer in the back side of the apron 50, and the side surface (including the back surface of the flange 1a) of the bathtub 1. FIG. Thereby, ultraviolet rays hit the photocatalyst layer at the time of ultraviolet irradiation, and active oxygen is generated, and the attached organic matter is efficiently decomposed.

  Each of the above embodiments shows an example of the present invention, and the present invention is not limited to each of the above embodiments.

  For example, the present invention can be applied to various bathroom members other than a bathtub lid, a bathroom chair, a bathroom brush, and various inspection opening lids.
