The light sensor 240 is a sensor whose internal resistance is changed by light, and does not operate when the bathroom lamp is off, but when the bathroom lamp is turned on. As the internal resistance value decreases, the detection signal is output to the controller 260. In this case, the light sensor 240 is preferably installed to be inclined upward about 45 °.

The weight sensor 250 configured as a magnetic switch is a sensor that detects that an object, such as a towel, is mounted on the object-hanging rod 220, and the object-hanger is mounted when the towel is mounted on the object-hanging rod 220. The load applied to the rod 220 is sensed to output a detection signal to the controller 260.

Therefore, when the detection signal is input from the infrared sensor 230 or the detection signal is input from the light sensor 240, the controller 260 determines that there is a person in the bathroom and is installed to face each other. UV sterilization lamp (212, 213) is stored in the (Off) state, and the detection signal is not input from the infrared sensor 230 and the light sensor 240, that is, the infrared sensor 230 And if the light sensor 240 does not operate, it is determined that there is no person in the bathroom to control the ultraviolet sterilization lamp (212) (213) to the On (On) state.

As a result, the controller 260 controls the UV germicidal lamps 212 and 213 to ON only when neither the infrared sensor 230 nor the light sensor 240 is operated. If the weight sensor 250 does not operate in the state in which both the 230 and the light sensor 240 are not operated at this time, there is no person in the bathroom, but it is determined that nothing is hanging on the object-hanging rod 220. In order to prevent the ultraviolet light from being unnecessarily controlled, the ultraviolet sterilization lamps 212 and 213 are controlled to an OFF state.

In addition, the controller 260 is a timer (so that the ultraviolet sterilization lamp 212, 213 does not remain in the ON state for too long in the state that the infrared sensor 230 and the light sensor 240 does not operate) 290) the UV sterilizer is repeated on / off at a predetermined time interval.

That is, if a person is not present in the bathroom and a towel or the like is placed on the object-hanging rod 220 while the bathroom light is turned off, the controller 260 may be a UV sterilizing lamp 212 (213). The lamp is turned on so that ultraviolet rays are irradiated with a towel placed on the object hanger rod 220 so that sterilization is performed. At this time, the controller 260 continues the ultraviolet sterilization lamp 212 for a long time by turning on / off the ultraviolet sterilization lamps 212 and 213 at predetermined time intervals according to the toggle signal input from the timer 290. 213 prevents operation.

In addition, the controller 260 controls the negative ion generator 280 so that negative ions can be generated only while the UV sterilizing lamps 212 and 213 are not operated, that is, while a person is present in the bathroom. On the contrary, the ultraviolet sterilization lamps 212 and 213 may be controlled to generate negative ions only while the ultraviolet rays are emitted. For reference, reference numeral 300 of FIG. 3 indicates a power supply unit supplying power required for driving each component and a lamp.
