It is provided with an injection means 46 that injects the disinfectant liquid upward (for example, directly above) in the disinfectant liquid in the storage tank 43 and ejects the disinfectant liquid upward from the upper surface of the floor means 44 in a liquid column.

Then, for example, the height H of the liquid columnar disinfectant for shoe disinfection that is ejected upward from the upper surface of the floor means 44 by adjusting the liquid level h by the adjusting means 45 according to the type of shoes K worn by a person. Is set.

Specifically, for example, as shown in FIG. 7, in the case of the short shoes K1, the liquid columnar disinfectant liquid is adjusted to a desired value so that the liquid level h of the disinfectant liquid in the storage tank 43 becomes relatively deep. Height H becomes lower. That is, in this case, the disinfectant liquid injected upward from each nozzle 65 of the injection means 46 receives a relatively large resistance due to the disinfectant liquid stored in the storage tank 43, so that the disinfectant liquid from the nozzle 65 is high. The H is a relatively small value (for example, H = 2 to 3 cm).

Further, for example, as shown in FIG. 8, in the case of the boots K2, the liquid level h of the disinfectant solution in the storage tank 43 is adjusted to a desired value so as to be shallower than that in the case of the short shoes K1. The height H of the disinfectant solution increases. That is, in this case, the disinfectant liquid jetted upward from each nozzle 65 of the injection means 46 has a small resistance due to the disinfectant liquid stored in the storage tank 43, so that the height H of the disinfectant liquid from the nozzle 65 is , A relatively large value (for example, H = 4 to 6 cm).

The floor means 44 is composed of, for example, a mesh-like support plate (mesh plate) 53 made of high-strength synthetic resin and an elastically deformable mesh-like mat 54 laid on the support plate 53 so as to be removable. ing. The thickness of the support plate 53 is, for example, about 1 cm, and the thickness of the mat 54 is, for example, about 1.5 cm.

The mat 53 is made of, for example, a cushioning artificial turf through which a disinfectant can pass, and is between a sheet-like base material, a large number of piles imitating turf leaves standing on the base material, and the piles. It has a filled filler. Then, when a person steps on the mat 53 with the shoe K, the entire bottom surface of the shoe K is immersed in the disinfectant liquid that has permeated the mat 53, and the disinfectant liquid flows by the injection of the nozzle 65 of the injection means 46. As a result, the disinfectant solution spreads to every corner of the bottom surface of the shoe K.

A downward injection means 38 is arranged at the center of the storage tank 43 in the longitudinal direction. Therefore, the inside of the storage tank 43 is divided into two, and the floor means 44 is also divided into two in the front-rear direction in the moving direction. For example, when the lower injection means 38 is not provided, the floor means 44 does not need to be divided and has a single plate shape.

Further, the adjusting means 45 has an overflow pipe 56 for adjusting the liquid level that can be raised and lowered with respect to the storage tank 43. The overflow pipe (drainage pipe) 56 is screwed to a support pipe 58 having a threaded portion 57, and rotates with respect to the support pipe 58 to move up and down. That is, the liquid level h of the disinfectant solution in the storage tank 43 can be adjusted by raising and lowering the overflow pipe 56 with respect to the storage tank 43.

Further, the injection means 46 has a front injection unit 61 located on the front side of the storage tank 43 and a rear injection unit 62 located on the rear side of the storage tank 43.

That is, the liquid level h of the boots K1 is adjusted to be deeper, and that of the boots K2 is adjusted to be shallower than that of the boots K1 (see FIGS. 7 and 8). The person to be disinfected may adjust the liquid level h.

Then, first, the control means 80 determines whether or not the circulation pump operating sensor 81 has detected a person, and determines that the sensor 81 has detected a person (the presence or absence of the person is detected by shading the detection light). In this case, the first circulation pump 71, the second circulation pump 73, and the third circulation pump 75 are operated.

Then, the disinfectant solution from the tank (not shown) side of the disinfectant solution supply means 70 circulates in the three circulation piping portions 10, 63, 63 while maintaining the low pressure state below the set pressure. At this time, the pressure valve of each nozzle is maintained in the closed state.

Next, the control means 80 determines whether or not the injection pump operating sensor 82 has detected a person, and when it is determined that the sensor 82 has detected a person (the presence or absence of the person is detected by shading the detection light). Stops each of the operating circulation pumps 71, 73, and 75, and operates the first injection pump 72, the second injection pump 74, and the third injection pump 76.

Then, the pressure of the circulating disinfectant rises to the set pressure, which opens each pressure valve, and as a result, all the nozzles (left and right lateral nozzles 21, 22, 23) at a predetermined timing. , Downward nozzles 26, 27, 28, upward nozzles 31, 32, 33, and nozzle 65 of the injection means 46) instantly and simultaneously (including substantially simultaneously) inject the disinfectant solution all at once.

Then, the disinfectant solution from each nozzle sterilizes the bacteria adhering to the person, and the disinfectant treatment for the whole person is efficiently performed.

After that, the control means 80 determines whether or not the operation stop sensor 83 has detected a person, and if it is determined that the sensor 83 has detected a person (the presence or absence of the person is detected by shading the detection light). , Stop each injection pump 72, 74, 76 that was operating. Then, the injection of the disinfectant solution from each nozzle is stopped, and the disinfection process for the person by the disinfectant solution is completed. In this way, the disinfection treatment is performed every time the person to be disinfected passes through the person moving area 2 one by one.

Then, according to such a disinfecting device 1, bacteria (pathogens and other bacteria) adhering to human clothes, shoes (short shoes K1 and boots K2), head, face, hands and the like are removed by the disinfecting solution from each nozzle. Various bacteria including) can be sufficiently sterilized as a whole, and therefore, a person can be appropriately sterilized as compared with a conventional device.

Further, by adjusting the liquid level h of the disinfectant liquid by the adjusting means 45, the height H of the disinfectant liquid ejected upward from the mat 53 of the floor means 44 can be set, so that the shoes worn by the person to be disinfected The height H of the disinfectant can be appropriately set according to the type of K, and thus the bacteria adhering to the shoes K can be sterilized even more sufficiently.

Furthermore, since it is configured to include circulation pumps 71, 73, 75, injection pumps 72, 74, 76, sensors 81, 82, 83, etc., it has good reactivity and can be disinfected appropriately and efficiently.
