3 is a flowchart illustrating a main process of automatically switching a power supply path according to whether a hand door is opened or closed according to an embodiment of the present invention.

Referring to FIG. 3 , when the hand door 100 is in a closed state (eg, there is no human entry), in the control unit 204, the contacts a1 and b1 of the first changeover switch 206a are connected, and the second By controlling the switch so that the contacts a2 and b2 of the changeover switch 206b are connected, the wireless power wirelessly received from the outside by the wireless power supply 208 is transmitted to the first UVA-LED 212a and the second UVA-LED 212b. The first sterilization that is respectively supplied to the operating power of the first UVA-LED (212a) and the second UVA-LED (212b) is irradiated to the glass tube 114 by generating first and second ultraviolet light, respectively. The mode is controlled to be performed (step 302).

Here, the first sterilization mode may be defined, for example, as a remote power control sterilization mode.

When the first sterilization mode is being performed, the sensor 202 detects whether the hand door 100 is opened or closed (open or closed), and transmits the detection result (open/closed detection signal) to the control unit 204 .

The control unit 204 checks whether the detection result provided from the sensor 202 is an open detection signal of the hand door 100 (step 304).

As a result of the check in step 304, if the detection result from the sensor 202 is an open detection signal of the hand door 100, the control unit 204 connects the contact a1 and the contact a1 of the first changeover switch 206a through the switch control. The contacts are switched (switched to the second sterilization mode) so that c1 is connected, and contacts a2 and c2 of the second changeover switch 206b are connected (step 306).

Here, the second sterilization mode may be defined as, for example, a self-power control sterilization mode.

Accordingly, the first battery unit 210a supplies battery power as the operating power of the first UVA-LED 212a through the paths of the contacts c1 and a1 of the first changeover switch 206a, and the second battery unit ( In 210b), the battery power is supplied as the operating power of the second UVA-LED 212b through the paths of the contacts c2 and a2 of the second changeover switch 206b.

As a result, the first UVA-LED 212a generates a first ultraviolet light and irradiates (radiates) in one direction of the glass tube 114 (eg, a lower direction of the glass tube 114), and the second UVA- The LED 212b generates a second ultraviolet light and irradiates (radiates) the other side of the glass tube 114 (eg, the upper direction of the glass tube 114 ).

When the second sterilization mode (a sterilization mode in which battery power is supplied as operating power of the first and second UVA-LEDs 212a and 212b) is being performed, the sensor 202 determines whether the hand door 100 is opened or closed (opened) or whether it is closed) and transmits the detection result (open/closed detection signal) to the control unit 204 .

The control unit 204 checks whether the detection result provided from the sensor 202 is a closing detection signal of the hand door 100 (step 308).

As a result of the check in step 308, if the detection result from the sensor 202 is a detection signal for closing the hand door 100, the control unit 204 connects the contact a1 and the contact a1 of the first changeover switch 206a through the switch control. By switching the contacts (switching to the second sterilization mode) so that b1 is connected and the contacts a2 and b2 of the second changeover switch 206b are connected, the second sterilization mode is returned to the first sterilization mode (step 310) .

Accordingly, the first and second UVA-LEDs 212a and 212b generate first and second ultraviolet light by operating power (wireless power received wirelessly from the outside) provided from the wireless power supply unit 208 to generate the first and second UVA-LEDs. (114) side is irradiated (radiated).

On the other hand, in the embodiment of the present invention, the first battery unit is mounted on one end (upper end) of the glass tube and the second battery unit is mounted on the other end (lower end) of the glass tube, but the present invention is necessarily limited to this. It is not possible to install the battery unit at a predetermined position under the wireless power receiver to switch the operating power of the UVA-LED depending on whether the hand door is opened or closed (switching the operating power supply between the wireless power supply unit and the battery unit). of course there is

In addition, although not shown in the drawings, a switch for turning on or off the execution of the sterilization mode through a user operation (user interface) may be further included.

On the other hand, in an embodiment of the present invention, the wireless power supply unit receives wireless power from the outside and supplies it as the operating power of the UVA-LED. Alternatively, it is of course also possible to design to generate optical power by mounting it at a predetermined position of the hand door, and supply the optical power generated in this way as the operating power of the UVA-LED.

The above description is merely illustrative of the technical idea of the present invention, and those of ordinary skill in the art to which the present invention pertains may make various substitutions, modifications, and changes within the scope not departing from the essential characteristics of the present invention. It will be easy to see that this is possible.
