Next, a usage example and a control example of the sterilization device 10 will be described. When the person 22 walks past the mat 32, the control unit 31 stops the pump 14 when standing or walking on a place other than the mat 32. On the other hand, when it is detected that the person 22 is standing at the standing position 33 for a predetermined time, for example, continuously for 2 seconds or more, the control unit 31 drives the pump 14 and the valve. Open 26. Therefore, the sterilizing liquid in the tank 13 passes through the supply path and is injected from the injection nozzle 15 to the front of the panel 12. Specifically, it is sprayed in the state of micro-fine particles of fine biomist, and can sterilize the clothes surface, hair, hands, etc. of the person 22. When the person 22 rotates the body at the standing position 33, the whole body on the front surface and the back surface of the body can be sterilized.

The control unit 31 stops the pump 14 and closes the valve 26 when 3 to 5 seconds have elapsed from the time when the disinfectant liquid is injected from the injection nozzle 15. While the person 22 in the standing position 33 remains in the standing position 33, the control unit 31 stops the pump 14 and closes the valve 26. Next, when a predetermined time elapses with the person 22 in the standing position 33 moving from the standing position 33 to another place and the other person 22 entering the standing position 33, the control unit 31 drives the pump 14. And open the valve 26. Whether or not the person 22 who was in the standing position 33 last time and the person 22 who was in the standing position 33 this time are the same person is determined by the face recognition function of the person detector 25.

As described above, in the sterilization device 10, the base 11 supports the tank 13, the pump 14, and the panel 12, and the panel 12 is provided with the injection nozzle 15, and the panel 12 is substantially perpendicular to the base 11. It is standing. Therefore, it is possible to prevent the sterilization device 10 from becoming large (compact), and it is possible to carry (transport) the sterilization device 10.

The control unit 31 can distinguish between the front surface and the back surface of the person 22 by processing the signal of the person detector 25. Then, by controlling the valve 26, the control unit 31 can make the amount of the disinfectant liquid sprayed on the front surface of the person 22 smaller than the amount of the disinfectant liquid sprayed on the back surface of the person 22. be. When this control is performed, the amount of the disinfectant liquid sprayed on the face of the person 22 can be reduced, and the person 22 can be prevented from having discomfort.

Further, the control unit 31 can change the amount of the sterilizing liquid to be sprayed according to the gender of the person 22 in the standing position 33. For example, control that the amount of the disinfectant liquid sprayed when the person 22 in the standing position 33 is a woman is smaller than the amount of the disinfectant liquid sprayed when the person 22 in the standing position 33 is a man. It can be performed. When this control is performed, it is possible to suppress the influence of the disinfectant solution on women's makeup, perfume and the like.

Further, the control unit 31 can change the position where the disinfectant liquid is sprayed, that is, the height, according to the height of the person 22 who is in the standing position 33. The height at which the disinfectant liquid is sprayed can be achieved, for example, by changing the number of jet nozzles 15. The taller the person 22, the more the number of injection nozzles 15 for injecting the sterilizing liquid is increased. The number of injection nozzles 15 for injecting the disinfectant liquid can be changed by opening and closing the valve 26. Further, the height at which the disinfectant liquid is injected may be achieved by changing the injection range of the injection nozzle 15 that injects the disinfectant liquid. The control unit 31 can change the injection range of the injection nozzle 15 in the height direction of the panel 12 by controlling the actuator 29 according to the height of the person 22 in the standing position 33.

Further, the control unit 31 can also adjust the amount of the sterilizing liquid injected from the injection nozzle 15 according to the detected carbon dioxide concentration. For example, the higher the carbon dioxide concentration, the more control is performed to increase the amount of the sterilizing liquid injected from the injection nozzle 15. Further, the control unit 31 can also adjust the amount of the sterilizing liquid injected from the injection nozzle 15 according to the detected humidity. For example, the higher the humidity, the more control is performed to reduce the amount of the sterilizing liquid injected from the injection nozzle 15. In the present embodiment, the method of controlling the injection amount of the disinfectant liquid is a method of changing the number of injection nozzles 15 for injecting the disinfectant liquid and a method of changing the amount of the disinfectant liquid injected by each injection nozzle 15. There is a way to change it.

Further, the control unit 31 can also display the body temperature of the person 22 detected by the person detector 25 and the detected carbon dioxide concentration on the display unit 30. Further, the control unit 31 can display a display informing the display unit 30 of the replenishment of the sterilizing liquid and the replacement of the tank 13 according to the remaining amount of the sterilizing liquid in the tank 13. Further, the control unit 31 can also transmit information notifying the replenishment of the sterilizing liquid and the replacement of the tank 13 to the external device 35. Further, the control unit 31 can transmit information from the communication unit 37 to the external device 35 when the detected carbon dioxide concentration is a predetermined value (for example, 900 ppm) or more. The management center can ventilate the space in which the sterilization device 10 is provided.
