A chemical solution is sent into each nozzle 9 through a flow dividing container 10 .

Compressed air is sent to the nozzle 9 to which the chemical solution is sent so that the chemical solution sent to the nozzle 9 is atomized from the nozzle 9 . Compressed air delivered to the nozzles 9 is delivered by a compressor 5 located outside the disinfection chamber 2 as shown in FIG. The compressor 5 compresses the air taken in from the outside and sends the compressed air toward the nozzle 9 inside the disinfection chamber 2 . The spray pressure of the chemical liquid sprayed from the nozzle 9 can be adjusted by the compressor 5. For example, the spray pressure of the chemical liquid sprayed from the nozzle 9 can be set to, for example, 0.2 Mpa or more and 0.4 Mpa or less. The compressor 5 includes a flow pipe 5a for sending compressed air toward the disinfection chamber 2, a control unit C for controlling the compressed air flowing from the flow pipe 5a, and the compressed air controlled by the control unit C in the disinfection chamber 2. and an air supply pipe 11 feeding each nozzle 9 . The controller C is a mechanism that adjusts the interval and time for conveying the compressed air sent from the compressor 5 to the nozzle 9 . The spraying conditions for spraying the chemical solution from the nozzle 9 can be adjusted by the controller C, such as by continuously or intermittently conveying the compressed air conveyed from the flow pipe 5a to the air supply pipe 11 for a predetermined period of time. A side wall 7 in the disinfection chamber 2 is provided with a switch (not shown) for starting spraying of the chemical liquid under the spraying conditions adjusted by the controller C or the like.

For example, the entire body of a person wearing clothes is disinfected by the adhesion device 1 having the above configuration. Next, a method of disinfecting the whole body of a person (user) wearing clothes with the adhesion device 1 will be described. First, the valve 3a of the chemical tank 3 and the valve 4b of the supply pump 4 are opened, and the pressure of the compressor 5 and the time for spraying the chemical from the nozzle 9 are controlled by the control unit C according to the spraying conditions for spraying the chemical from the nozzle 9. Adjust. Then, the supply pump 4 and the compressor 5 are operated so that the chemical liquid can be sprayed from the nozzle 9. - 特許庁Next, the person wearing the clothes (the user who disinfects the whole body) opens the door D, enters the disinfection room 2, and closes the door D. When the door D is closed, the inside of the disinfection chamber 2 is sealed so that the airflow in the disinfection chamber 2 does not leak to the outside. After closing the door D, the user stands with his/her feet spread so that the sole of the right foot is positioned within the mark M1 and the sole of the left foot is positioned within the mark M2 shown in FIG. So to speak, take a pose like the letter T. Preparations for disinfecting the user are thus completed.

When preparations for disinfection are completed, the user manually pushes a switch (not shown) attached to the inner wall of the disinfection chamber 2 . Then, the pressing of the switch is detected by the control section C, and the chemical solution is sprayed from the nozzle 9 under the preset conditions. For example, the chemical solution is sprayed continuously for 20 seconds from all the nozzles 9, followed by an interval of 5 seconds, which is repeated four times, and finally the chemical solution is sprayed continuously from all the nozzles 9 for 20 seconds. Then, after an interval of 30 seconds, spraying of the chemical solution is completed. After the spraying of the chemical solution is finished, the user goes out of the disinfection room 2 through the door D. In this way, the disinfection of the whole body of the clothed person is completed. Once one person's disinfection is finished, another person can disinfect in the same way.

Positional relationship in plan view of nozzles 9a1 and 9a2, central axis A of nozzles 9a1 and 9a2, mark M indicating standing position of person, first and second imaginary straight lines IL1 and IL2, imaginary quadrangle IQ, and imaginary circular region R5 is shown in FIG. In FIG. 21, the center axes A of the nozzles 9a1 and 9a2 do not intersect the second imaginary straight line IL2. In addition, the central axes A of the nozzles 9a1 and 9a2 extend from the virtual circular region R5 to the region R1 corresponding to the mark M1, the region R2 corresponding to the mark M2, and the region R3 sandwiched between the marks M1 and M2. The removed area and the area of the virtual square IQ intersect with the floor surface 6a located in the overlapping area (hatched area DR in FIG. 23). In other words, in the plan view of FIG. 23, the central axes A of the nozzles 9a1 and 9a2 are arranged in the shaded area DR so as not to intersect the second imaginary straight line IL2 and not overlap the areas R1, R2, and R3. To position. Further, the nozzles 9b1 and 9b2, the central axis A of the nozzles 9b1 and 9b2, the mark M indicating the standing position of the person, the third and fourth virtual straight lines IL3 and IL4, the virtual quadrangle IQ, and the virtual circular region R5 in plan view The positional relationship is shown in FIG. In FIG. 22, the center axes A of the nozzles 9b1 and 9b2 do not intersect the fourth imaginary straight line IL4. In addition, the center axes A of the nozzles 9b1 and 9b2 extend from the virtual circular region R5 to the region R1 corresponding to the mark M1, the region R2 corresponding to the mark M2, and the region R3 sandwiched between the marks M1 and M2. The removed area and the area of the virtual square IQ intersect the floor surface 6a located in the overlapping area (hatched area DR in FIG. 24). In other words, in a plan view of FIG. 24, the central axes A of the nozzles 9b1 and 9b2 are arranged in the shaded area DR so as not to intersect the fourth imaginary straight line IL4 and not overlap the areas R1, R2, and R3. To position. Therefore, the liquid medicine sprayed from each nozzle 9 is, so to speak, the floor surface 6a (the floor surface 6a located in the hatched area DR in FIGS. 23 and 24) located near the person, which is the outer peripheral portion of the person's feet. It is sprayed on the target. After hitting the floor surface 6a, the sprayed airflow rises so that part of the airflow follows the person. Therefore, it is possible to evenly attach the liquid medicine to the clothes and the person wearing the clothes, as compared with the case where the liquid medicine is sprayed toward a specific part of the person. Further, as shown in FIG. 20, a floor surface 6a located within an imaginary circular region R5 whose diameter is a straight line DM connecting the ends LP and RP of a person standing in a standing position with both hands spread out in the horizontal direction. (Floor surface 6a located in hatched area DR in FIGS. 23 and 24) Since the spray is directed toward the person standing, even when the person who is standing spreads his/her hands horizontally, The chemical solution can be adhered evenly. In addition, the water-repellent coating layer provided on the inner surface of the side wall 7 of the inner surface of the disinfection chamber 2 makes it difficult for the chemical solution sprayed into the disinfection chamber 2 to adhere to the inner surface of the side wall 7, so that it is sprayed into the disinfection chamber 2. Airflow can be increased. As a result, it becomes possible to increase the amount of the liquid medicine to be applied to the person.

EXAMPLES The present invention will be specifically described below with reference to experimental examples, but these are not intended to limit the present invention.

First, the items generally common to Experimental Examples 1 to 31 will be described. As the adhesion device 1, a rectangular parallelepiped disinfecting chamber 2 having a width of 1.65 m, a depth of 0.74 m, and a height of 2.4 m was prepared. was installed. Each installed nozzle 9 has a center axis A shown in FIG. ) and the floor surface 6a located outside the area sandwiched between the right sole area and the left sole area (area corresponding to the area R3). As the nozzle 9, an air atomizing humidifier nozzle manufactured by Spraying System Japan was used. As the chemical solution sprayed from the nozzle 9, non-electrolyzed weakly acidic hypochlorous acid water (pH 6.5, residual chlorine concentration 50 ppm) called CELA (registered trademark) water was used. As the conditions for spraying the chemical solution from the nozzle 9, the spray amount of the nozzle 9 was set to 0.69 ml/sec, and the Sauter mean particle diameter sprayed from the nozzle 9 was set to 8.5 μm. For the person who disinfects the whole body (clothed person) in the disinfection room 2, each part of the body (as shown in Figs. A4, neck A5, chest B1, abdomen B2, right flank B3, left flank B4, back B5, waist B6, crotch B7, right upper arm front HR1, right forearm front HR2, right upper arm back HR3, right forearm back HR4, left upper arm Front HL1, left forearm front HL2, left upper arm back HL3, left forearm back HL4, right thigh front LR1, right shin LR2, right thigh back LR3, right calf LR4, right inner thigh LR5, left thigh front LL1, left shin LL2, Gauze of 10 cm x 10 cm was attached to 30 places (LL3 on the back of the left thigh, LL4 on the left calf, and LL5 on the left thigh). Then, a state (T pose), and the chemical solution is sprayed from all the nozzles 9. Twenty seconds after the start of spraying, the person in the disinfection room 2 rotates 90 degrees around the vertical direction on the spot, and the right sole is positioned on the mark M'1 and the left sole is positioned on the mark M'2. At the same time, a pose (Akimbo pose) is taken in which both hands are placed on the waist so as not to touch the side wall 7 with the hands. Then, after another 20 seconds, it rotates 90 degrees in the opposite direction and assumes a state in which both hands are spread horizontally (the initial T-shaped pose). After that, each pose is repeated every 20 seconds such as Akimbo's pose→T-shaped pose→Akimbo's pose→T-shaped pose. After a predetermined time has passed since the spraying of the chemical solution, stop spraying the chemical solution, go out of the disinfection room 2 through the door D, remove the 10 cm × 10 cm gauze attached to each part of the body, and enter the disinfection room 2. The value obtained by dividing the absolute value of the difference in gauze weight (g) by 100 cm ² was measured as the wet amount of the chemical liquid adhering to the person (mg/cm ² ).

In Experimental Examples 1 to 6, each nozzle 9 was attached to each corner in the disinfection chamber 2, and the spray pressure of the chemical solution sprayed from each nozzle 9 was set to 0.3 Mpa. In addition, from the start of spraying of the chemical solution, the chemical solution was sprayed for 20 seconds, intermittent spraying was performed four times at intervals of 5 seconds, and finally the chemical solution was sprayed for 20 seconds (in disinfection room 2, hypochlorous acid The density of water is assumed to be 94.2 g/m ³ ). After spraying the last chemical solution, the pose was not changed, the same posture was maintained for 30 seconds, and the subject went out of the disinfection room 2 through the door D to measure the amount of water that landed. While the angle a formed by the central axis A of the nozzle 9 and the imaginary vertical line IV shown in FIG. The angle b is 0 degrees, the angle b is 5 degrees in Experimental Example 2, the angle b is 10 degrees in Experimental Example 3, the angle b is 15 degrees in Experimental Example 4, and the angle b is 30 degrees in Experimental Example 5. degree, and in Experimental Example 6, the measurement was performed with the angle b formed at 45 degrees.

FIG. 9 shows the measurement results of Experimental Examples 1-6. FIG. 9 does not show the amount of water landing on the front of the left forearm in Experimental Example 6 (angle b is 45 degrees), but the specific amount of water landing was 10.3. If the angle b is 45 degrees, the amount of water that lands on the body will vary greatly, and the chemical solution will not evenly adhere to the entire body.

In Experimental Examples 7 to 11, each nozzle 9 was attached to each corner in the disinfection chamber 2, and the angle a formed in FIG. 5 was fixed at 10 degrees, and the angle b formed in FIG. 6 was fixed at 5 degrees. Further, in Experimental Examples 7, 8, 10, and 11, the chemical solution was sprayed for 20 seconds from the start of spraying the chemical solution, intermittent spraying was performed four times at intervals of 5 seconds, and finally the chemical solution was sprayed for 20 seconds. bottom. After the last spraying of the chemical solution was completed, the pose was not changed, the same posture was maintained for 30 seconds, and the amount of water landing was measured by going out of the disinfection room 2 from the door D (total chemical spraying time of 100 seconds ). In Experimental Example 9, the chemical solution was sprayed for 20 seconds from the start of spraying, intermittent spraying was performed three times at intervals of 5 seconds, and finally the chemical solution was sprayed for 20 seconds. After the last chemical spray was finished, the pose was not changed, the same posture was maintained for 30 seconds, and the amount of water landing was measured outside the disinfection room 2 from the door D (total chemical spray time of 80 seconds). . The spray pressure of the chemical liquid sprayed from each nozzle 9 was 0.2 Mpa in Experimental Example 7, 0.3 Mpa in Experimental Example 8, 0.4 Mpa in Experimental Example 9, and 0.4 Mpa in Experimental Example 10. 11 was 0.3 Mpa (however, the chemical solution was sprayed while the door D of the adhesion device 1 was open).

FIG. 10 shows the measurement results of Experimental Examples 7-11. When the door D was opened as shown in Experimental Example 11, a sufficient amount of water landing could not be obtained at all due to the influence of the outside air. When the spray pressure was 0.2 Mpa or more and 0.4 Mpa or less, it was possible to evenly adhere the liquid medicine to the whole body. As can be seen from the comparison between Experimental Examples 9 and 10, the longer the spraying time of the chemical liquid, the greater the amount of water that could be deposited on the whole body.

In Experimental Examples 12 to 14, each nozzle 9 was attached to each corner in the disinfection chamber 2, and the spray pressure of the chemical solution sprayed from each nozzle 9 was set to 0.3 Mpa. Further, the chemical solution was sprayed for 20 seconds from the start of spraying, intermittent spraying was performed four times at intervals of 5 seconds, and finally the chemical solution was sprayed for 20 seconds. After spraying the last chemical solution, the pose was not changed, the same posture was maintained for 30 seconds, and the subject went out of the disinfection chamber 2 through the door D to measure the amount of water that landed. While the angle b in FIG. 6 is fixed at 5 degrees, in Experimental Example 12, the angle a in FIG. Measurements were taken as degrees.

FIG. 11 shows the measurement results of Experimental Examples 12-14. When the angle a in FIG. 5 was 5 degrees or more and 15 degrees or less, a sufficient amount of water landing exceeding approximately 0.5 was obtained over the whole body, and the chemical solution could be applied evenly.

In Experimental Examples 15 and 16, each nozzle 9 was attached to each corner in the disinfection chamber 2, and the spray pressure of the chemical solution sprayed from each nozzle 9 was set to 0.3 Mpa. In addition, the chemical solution was sprayed continuously for 100 seconds from the start of spraying of the chemical solution. After spraying the chemical solution, the pose was not changed and the same posture was maintained for 30 seconds. While the angle b in FIG. 6 was fixed at 5 degrees, the measurement was performed with the angle a in FIG.

FIG. 12 shows the measurement results of Experimental Examples 15 and 16. FIG. Compared with Experimental Examples 12 and 13 (FIG. 11) in which the chemical solution was sprayed intermittently, in Experimental Examples 15 and 16 (FIG. 12) in which the chemical solution was sprayed continuously, the amount of water landing was larger than that in the case of intermittent spraying of the chemical solution. is conspicuous. This is because when the chemical solution is sprayed intermittently, the sprayed chemical solution collides with the air current of the chemical solution floating in the disinfection chamber 2 when the chemical solution is sprayed again at intervals in which the chemical solution is not sprayed. It is presumed that this is because diffusion of the chemical solution is promoted.

In Experimental Examples 17 to 19, nozzles 9 were attached at positions of 0.185 m and 0.555 m from the front in the depth direction of the disinfection chamber 2, respectively, and the spray pressure of the chemical solution sprayed from each nozzle 9 was 0.3 Mpa. made it In addition, the chemical solution was sprayed continuously for 100 seconds from the start of spraying of the chemical solution. After spraying the chemical solution, the pose was not changed and the same posture was maintained for 30 seconds. While the angle b formed in FIG. 6 is fixed at 0 degrees, in Experimental Example 17, the angle a formed in FIG. Measurements were taken as degrees.

FIG. 13 shows the measurement results of Experimental Examples 17-19. Even when the chemical solution is sprayed continuously, if the angle b formed in FIG. 6 is 0 degrees and the angle a formed in FIG. A sufficient amount of water was obtained, and the chemical solution could be applied evenly.

In Experimental Examples 20 and 21, the nozzles 9 were attached at positions of 0.185 m and 0.555 m from the front in the depth direction of the disinfection chamber 2, respectively, and the spray pressure of the chemical solution sprayed from each nozzle 9 was 0.3 Mpa. made it In addition, the chemical solution was sprayed continuously for 100 seconds from the start of spraying of the chemical solution. After spraying the chemical solution, the pose was not changed and the same posture was maintained for 30 seconds. The angle b formed in FIG. 6 was fixed at 0 degree. In Experimental Example 20, the angle a formed by the first nozzle pair 9a in FIG. 5 was set to 15 degrees, and the angle a formed by the second nozzle pair 9b was set to 10 degrees. In Experimental Example 21, the angles a formed by the first nozzle pair 9a were 15 degrees and 10 degrees, and the angles a formed by the second nozzle pair 9b were 15 degrees and 10 degrees. are at the same angle and measured.

FIG. 14 shows the measurement results of Experimental Examples 20 and 21. FIG. As can be seen from the graph of Experimental Example 20, by making the angle a formed by each of the first and second nozzle pairs 9a and 9b the same, the amount of water deposited on the entire body exceeds 1, and the chemical solution can be applied very evenly. was made. On the other hand, when the angle a formed by each of the first and second nozzle pairs 9a and 9b was changed, the amount of landing water varied slightly.

In Experimental Example 22, measurement was performed by changing the angle a formed by the first and second nozzle pairs 9a and 9b from that in Experimental Example 20. FIG. Specifically, the angle a formed by the first nozzle pair 9a was set at 15 degrees, and the angle a formed by the second nozzle pair 9b was set at 5 degrees.

FIG. 15 shows the measurement results of Experimental Example 22. As shown in FIG. We were able to obtain an amount of water that was more than 1 over the whole body, and we were able to apply the chemical solution very evenly. As can be seen from Experimental Example 20 in FIG. 14, by making the angles a formed by the first and second nozzle pairs 9a and 9b the same, the chemical solution can be applied evenly.

In Experimental Examples 23 to 25, the nozzles 9 were attached at positions of 0.185 m and 0.555 m from the front in the depth direction of the disinfection chamber 2, respectively, and the spray pressure of the chemical solution sprayed from each nozzle 9 was 0.3 Mpa. made it In addition, the chemical solution was sprayed continuously for 100 seconds from the start of spraying of the chemical solution. After spraying the chemical solution, the pose was not changed and the same posture was maintained for 30 seconds. Also, the angle b formed in FIG. 6 is fixed at 0 degree. In Experimental Example 23, the angles a formed in FIG.

FIG. 16 shows the measurement results of Experimental Examples 23-25. Compared to Experimental Examples 20 and 22 (FIGS. 14 and 15) in which the angle a formed between the first nozzle pair 9a and the second nozzle pair 9b is different, the angle between the first nozzle pair 9a and the second nozzle pair 9b is In Experimental Examples 23 to 25 (FIG. 16) in which the formed angle a was the same, slight variations occurred in the amount of water landing on the whole body. Therefore, by making the angle a different between the first nozzle pair 9a and the second nozzle pair 9b, the sprayed chemical solution is effectively diffused, and the chemical solution evenly adheres to the whole body.

In Experimental Examples 26 to 28, nozzles 9 were attached at positions of 0.185 m and 0.555 m from the front in the depth direction of the disinfection chamber 2, respectively, and the spray pressure of the chemical solution sprayed from each nozzle 9 was 0.3 Mpa. made it From the start of spraying of the chemical solution, the chemical solution was sprayed for 20 seconds, intermittent spraying was performed four times at intervals of 2 seconds, and finally the chemical solution was sprayed for 20 seconds. After the last spraying of the chemical solution was completed, the pose was not changed, the same posture was maintained for 30 seconds, and the amount of water landing was measured by going out of the disinfection room 2 from the door D (total chemical spraying time of 100 seconds ). Also, the angle a formed by the first nozzle pair 9a in FIG. 5 was set to 15 degrees, the angle a formed by the second nozzle pair 9b was set to 10 degrees, and the angle b formed in FIG. 6 was fixed to 0 degrees. In Experimental Example 26, the amount of liquid sprayed from each nozzle 9 was set to 0.69 ml/sec to 0.28 ml/sec, and the Sauter mean particle size sprayed from the nozzles 9 was set to 7.6 μm (the amount of liquid sprayed from the nozzles 9 was set to 7.6 μm). 2, the density of the hypochlorous acid water was set to 38.2 g/m ³ ). In Experimental Example 27, the spray amount of each nozzle 9 was set to 0.83 ml/sec, and the Sauter average particle size sprayed from the nozzles 9 was set to 9.0 μm (in the disinfection chamber 2 after the chemical solution spraying, hypochlorous acid water density of 113.3 g/m ³ ), in Example 28, the amount of liquid sprayed from each nozzle 9 was 1.25 ml/sec, and the Sauter mean particle size sprayed from the nozzle 9 was 11.2 μm (end of chemical spraying) In the subsequent disinfection room 2, the density of the hypochlorous acid water was set to 170.6 g/m ³ ) and measured.

FIG. 17 shows the measurement results of Experimental Examples 26-28. FIG. 17 does not show the water landing amount in the upper right table of Experimental Example 28, but the specific water landing amount was 12.1. As shown in FIG. 17, when the amount of liquid sprayed from each nozzle 9 was set to 0.28 ml/sec, there were many places where the amount of landing water was less than 0.5, and a sufficient amount of landing water was not obtained. As shown in Experimental Example 20 and Experimental Examples 27 and 28 in which the amount of liquid sprayed from each nozzle 9 is 0.69 ml/sec, the amount of liquid sprayed from each nozzle 9 is 0.69 ml/sec or more and 1.25 ml/sec. If it is below (if the density of hypochlorous acid water is 94.2 g/m ³ or more and 170.6 g/m ³ or less in the disinfection chamber 2 after chemical spraying), 0.5 for the whole body was obtained, and the chemical solution could be applied evenly.

In Experimental Example 29, measurement was performed under the same conditions as in Experimental Example 28 except that the angle a formed by the first nozzle pair 9a in FIG. 5 was 15 degrees and the angle a formed by the second nozzle pair 9b was 5 degrees.

FIG. 18 shows the measurement results of Experimental Example 29. FIG. Although the amount of water landing on the crotch was 0.5, a very high amount of water landing was obtained on the other portions. The reason why the amount of water landing on the crotch was 0.5 was that the gauze attached to the crotch was sandwiched between the crotch to measure the amount of water landing, and a sufficient adhesion area for the chemical solution to adhere to the gauze could not be secured. This is probably because there was no

In Experimental Example 30, the conditions were the same as in Experimental Example 27, except that the angle a formed by the first nozzle pair 9a in FIG. 5 was 15 degrees, and the angle a formed by the second nozzle pair 9b was 5 degrees. For this purpose, we measured the amount of water landing only on a specific part. In Experimental Example 31, the chemical solution was sprayed for 15 seconds from the start of spraying, intermittent spraying was performed four times at intervals of 2 seconds, and finally the chemical solution was sprayed for 15 seconds. After the last spray of the chemical solution is finished, do not change the pose, keep the same posture for 30 seconds, go out of the disinfection room 2 from the door D and measure the amount of water landing (total chemical solution spray time of 75 seconds). The conditions were the same as in Experimental Example 29, except that the measurement time was shortened.

FIG. 19 shows the measurement results of Experimental Examples 30 and 31. FIG. Even when the spray amount of each nozzle 9 is 0.83 ml/second, even if the angle a formed by the first and second nozzle pairs 9a in FIG. was obtained. Further, as shown in Experimental Example 31, by increasing the amount of water liquid sprayed per second at 1.25 ml/sec from each nozzle 9, the chemical liquid spraying time was shortened from 100 seconds to 75 seconds. Also, the amount of landing water exceeding 1 was obtained in most parts. Therefore, if the chemical solution spraying time is 75 seconds or more and 100 seconds or less, the chemical solution can be evenly attached to the whole body.

In some of the above experimental examples, when measuring the amount of water landing by removing the 10 cm × 10 cm gauze, the left side of the head A4, the chest B1, the crotch B7, the waist B6, and the back of the right upper arm HR3 in FIGS. When the residual chlorine concentration was measured with hypochlorous acid test paper for the gauze of the left thigh table LL1, a residual chlorine concentration of 10 ppm or more was confirmed in each case.

Next, the items generally common to Examples 32 to 39 will be described. As the adhesion device 1, a rectangular parallelepiped disinfecting room 2 with a width of 1.65 m, a depth of 0.74 m, and a height of 2.4 m is prepared. The nozzles 9 were attached to the positions on both sides, respectively, and the spray pressure of the chemical solution sprayed from each nozzle 9 was set to 0.3 Mpa. 6 is fixed at 0 degree, while the angle a formed in FIG. Placed in DR. As the nozzle 9, an air atomizing humidifier nozzle manufactured by Spraying System Japan was used. As the chemical solution sprayed from the nozzle 9, non-electrolyzed weakly acidic hypochlorous acid water (pH 6.5, residual chlorine concentration 50 ppm) called CELA (registered trademark) water was used. As the conditions for spraying the chemical solution from the nozzle 9, the spray amount of the nozzle 9 was set to 1.25 ml/sec, and the Sauter mean particle diameter of the sprayed from the nozzle 9 was set to 11.2 μm. For a person (clothed person) whose whole body is to be disinfected in the disinfection room 2, gauze of 10 cm×10 cm was attached to each part of the body in the same manner as in Example 1 and the like. Then, stand with your feet spread and your hands spread horizontally so that the sole of your right foot is positioned within the mark M1 and the sole of your left foot is positioned within the mark M2 on the floor 6a in the disinfection chamber 2 shown in FIG. ), and the chemical solution is sprayed from all the nozzles 9. Twenty seconds after the start of spraying, the person in the disinfection room 2 rotates 90 degrees around the vertical direction on the spot, and the right sole is positioned on the mark M'1 and the left sole is positioned on the mark M'2. At the same time, a pose (Akimbo pose) is taken in which both hands are placed on the waist so as not to touch the side wall 7 with the hands. Then, after another 20 seconds, it rotates 90 degrees in the opposite direction and assumes a state in which both hands are spread horizontally (the initial T-shaped pose). After that, each pose is repeated every 20 seconds such as Akimbo's pose→T-shaped pose→Akimbo's pose→T-shaped pose. After a predetermined time has passed since the spraying of the chemical solution, stop spraying the chemical solution, go out of the disinfection room 2 through the door D, remove the 10 cm × 10 cm gauze attached to each part of the body, and enter the disinfection room 2. The value obtained by dividing the absolute value of the difference in gauze weight (g) by 100 cm ² was measured as the wet amount of the chemical liquid adhering to the person (mg/cm ² ).

In Experimental Examples 32 and 33, the chemical solution was sprayed for 25 seconds from the start of spraying the chemical solution, followed by an interval of 2 seconds, and then the chemical solution was sprayed for 21 seconds, followed by an intermittent spray (21 seconds interval). After performing chemical solution spraying and intermittent spraying with an interval of 2 seconds) four times, it went out of the disinfection room 2 from the door D and measured the amount of water landing. In Experimental Example 32, the water-repellent paint was evenly applied to the inner surface of the side wall 7, whereas in Example 33, the side wall 7 was not coated with the water-repellent paint and the measurement was performed.

FIG. 25 shows the measurement results of Experimental Examples 32 and 33. FIG. When the side wall 7 was coated with the water-repellent paint as shown in Experimental Example 32, a larger amount of the chemical solution could adhere to each part of the whole body than in Example 33 where the water-repellent paint was not applied.

In Experimental Examples 34 and 35, the chemical solution was sprayed for 22 seconds from the start of spraying the chemical solution, followed by an interval of 2 seconds. After performing chemical solution spraying and intermittent spraying with an interval of 2 seconds) four times, it went out of the disinfection room 2 from the door D and measured the amount of water landing. In Experimental Example 34, the water-repellent paint was evenly applied to the inner surface of the side wall 7, whereas in Example 35, the side wall 7 was not coated with the water-repellent paint and the measurement was performed.

FIG. 26 shows the measurement results of Experimental Examples 34 and 35. FIG. When the side wall 7 was coated with the water-repellent paint as shown in Experimental Example 34, a larger amount of the chemical solution could adhere to each part of the whole body than in Example 35 where the water-repellent paint was not applied.

In Experimental Examples 36 and 37, the chemical solution was sprayed for 22 seconds from the start of spraying the chemical solution, followed by an interval of 2 seconds. After performing chemical solution spraying and intermittent spraying with an interval of 2 seconds) four times, it went out of the disinfection room 2 from the door D and measured the amount of water landing. In Experimental Example 36, the water-repellent paint was evenly applied to the inner surface of the side wall 7, whereas in Example 37, the side wall 7 was not coated with the water-repellent paint and the measurement was performed.

FIG. 27 shows the measurement results of Experimental Examples 36 and 37. FIG. When the side walls 7 were coated with the water-repellent paint as shown in Experimental Example 36, more chemical solution could be attached to each part of the whole body than in Example 37 where the water-repellent paint was not applied.

In Experimental Examples 38 and 39, the chemical solution was sprayed for 18 seconds from the start of spraying the chemical solution, followed by an interval of 2 seconds. After performing chemical solution spraying and intermittent spraying with an interval of 2 seconds) four times, it went out of the disinfection room 2 from the door D and measured the amount of water landing. In Experimental Example 38, the inner surface of the side wall 7 was evenly coated with the water-repellent paint, whereas in Example 39, the side wall 7 was not coated with the water-repellent paint and the measurement was performed.

FIG. 28 shows the measurement results of Experimental Examples 38 and 39. FIG. When the side wall 7 was coated with the water-repellent paint as shown in Experimental Example 38, more chemical solution could adhere to each part of the whole body than in Example 39 where the water-repellent paint was not applied.

From the above experimental examples, the chemical solution sprayed from each nozzle 9 is outside the feet of the person in the disinfection chamber 2 (the right sole area, the left sole area, and the area sandwiched between the right sole area and the left sole area), so to speak. , the area near the person (floor surface 6a located in the hatched area DR in FIGS. 23 and 24), which is the outer periphery of the person's feet, is sprayed toward the floor surface 6a. It becomes possible. Specifically, it is effective if the angle a in FIG. 5 is 5 degrees or more and 15 degrees or less, and the angle b in FIG. 6 is 0 degrees or more and 30 degrees or less. 5 between the first nozzle pair 9a and the second nozzle pair 9b, the sprayed chemical solution can be effectively diffused, and the chemical solution can evenly adhere to the whole body. It becomes possible. If the angle b in FIG. 6 is set to 0 degree, only the angle a needs to be adjusted when the nozzle 9 is installed in the disinfection chamber 2, which facilitates the adjustment. Even when the formed angle b is 0 degrees, the liquid medicine can be evenly applied to the whole body as shown in FIG. As shown in FIGS. 23 and 24, the central axis A of each nozzle 9 is positioned in the shaded area DR and is positioned so as not to intersect with the areas R1, R2 and R3, so that the marks M1 and M2 stand at the standing positions. Even when a person spreads both hands in the horizontal direction, the liquid medicine can be evenly attached to the person's clothes and person.

Further, from Experimental Examples 32 to 39, the chemical solution sprayed into the disinfection chamber 2 by the water-repellent coating layer (the surface layer coated with the applied water-repellent paint) provided on the inner surface of the inner side wall 7 of the disinfection chamber 2 becomes less likely to adhere to the inner surface of the side wall 7, and it is possible to increase the amount of liquid medicine to be adhered to a person.

Although the embodiment of the present invention has been described above, the present invention is not limited to the specific description, and it is also possible to combine the exemplified configurations etc. within a technically consistent range and implement them as appropriate. Alternatively, some elements and processes can be implemented by replacing them with known forms.

In the above description, as the central axis A of the nozzle 9 shown in FIG. 2, in addition to FIG. If it intersects with the floor surface 6a located outside the area where it is placed), various arrangements may be made.

In the above, an example in which one person enters the disinfection room 2 for disinfection is shown. A plurality of persons may be sterilized at once by arranging persons so as to be sandwiched between the second nozzle pair 9a and 9b.

In the above, as shown in FIG. 2, the four nozzles 9 are arranged in a rectangular shape in plan view, but the four nozzles 9 may be arranged in a square shape.

23 and 24 show an example in which the central axis A of each nozzle 9 extends toward the inner side of the hatched area DR, but the center axis A is arranged so as to overlap the outer edge (virtual second side IS2) of the hatched area DR. Good if located.

In the above, an example of spraying the chemical liquid toward the floor surface 6a located outside the mark M was shown, but instead of using the mark M as a reference, a person standing in the disinfection room 2 The central axis A of the nozzle 9 may be set based on the position of the foot. For example, the right sole region of a person standing in the disinfection room 2 based on the mark M is defined as region R1, the left sole region is defined as region R2, and the region sandwiched between the right and left sole regions is defined as region R3. The central axis A of the nozzle 9 may be set so as not to overlap the regions R1 to R3.

In the above example, the water-repellent coating layer is provided on the inner surface of the side wall 7, but the water-repellent coating layer may be provided on the floor surface 6a. As a result, the chemical solution sprayed toward the floor surface 6a is less likely to adhere to the floor surface 6a, and the sprayed chemical solution is more likely to adhere to the floor surface 6a. In the above description, an example in which the water-repellent coating layer is provided on the entire inner surface of the side wall 7 is shown, but the water-repellent coating layer may be provided only on a part of the side wall 7 that is likely to be hit by the airflow of the sprayed chemical solution. . By attaching the nozzle 9 to the side wall 7 provided with the water-repellent coating layer, when the chemical sprayed from the nozzle 9 spreads from the nozzle 9 as a starting point, the chemical spread from the nozzle 9 spreads to the side wall 7 located around the nozzle 9. Adhesion is suppressed, the air flow rate of the chemical solution directed to the person can be increased, and the chemical solution is more likely to adhere to the person.
