FIG. 2 is a graph showing inactivation levels of Staphylococcus aureus according to irradiation time and irradiation time of ultraviolet rays of a drain plug having an ultraviolet sterilizing function according to an embodiment. FIG.

Hereinafter, the operation and effects of the drain cap having the ultraviolet sterilizing function according to the present embodiment will be described with reference to FIGS. 3 to 9. FIG.

3 and 4, a drain plug 100 having an ultraviolet sterilizing function according to the present embodiment is installed to open and close a drain hole 12 provided in a bottom portion of a sink ball 11, The operation for disinfecting the drain plug 100 having the ultraviolet sterilizing function is performed by the control unit 150 so as to perform a sterilizing operation on the drain sump 14 and the sieve 15 inside the drain sill 12, .

The operation of the drain plug 100 having the ultraviolet sterilizing function for performing the sterilizing action on the drainage tank 14 and the sieve 15 inside the drain hole 12 is performed by the operation of the switch 170 or the like provided on the handle 115 May be initiated by operation.

For example, when the user holds the handle 115 to close the drain port 12 with the stopper body 110, and then inputs an operation signal through the switch 170, the operation signal is transmitted to the controller 150 When the operation signal is transmitted to the control unit 150, the control unit 150 starts controlling the operation of the power supply unit 130.

The controller 150 senses the position of the cap main body 110 and acquires the information about the position and the posture of the cap main body 110. The controller 150 detects the position of the cap main body 110, It is determined whether or not the drain hole 12 of the plug body 110 is opened or closed.

The control unit 150 controls the operation of the power supply unit 130 so that power is supplied to the LED 120. When the drainage hole 12 is closed by the cap body 110, The control unit 150 controls the operation of the power supply unit 130 so as not to supply power to the LED 120. When the control unit 150 determines that the power supply unit 130 is not open or the drain port 12 is not properly closed by the cap body unit 110, do.

By controlling the operation of the LED 120 only when the drain port 12 is closed by the cap body 110 as described above, the drain cap 100 having the ultraviolet sterilizing function is operated inefficiently It is possible to reduce the risk of a safety accident and to prevent the ultraviolet rays irradiated by the LED 120 from flowing out of the drain hole 12 to have a detrimental effect on the human body.

When power is supplied to the LED 120 by the operation of the control unit 150 as described above, the LED 120 is turned on and irradiates ultraviolet rays toward the drain tank 14 and the sieve 15 .

At this time, the LED 120 emits ultraviolet rays having strong sterilizing properties, for example, ultraviolet rays having a peak wavelength within 270 to 280 nm, more preferably ultraviolet rays having a peak wavelength at 275 nm.
