  The combination of the fan and the sterilizing ion generating element and the air purifier incorporating the sterilizing ion generating element in Patent Documents 1 and 2 described above are both sprayed with sterilizing ions in a closed space or the like. In order to inactivate bacteria and viruses floating or adhering in the room, it takes a considerable amount of time to make the sterilization effect of the sterilization ions effective in the room. In addition, if there are people in and out of the room, there is a risk of new bacteria and viruses entering, making it difficult to maintain the sterilizing effect. It becomes difficult to efficiently distribute ions into the room, and it takes time to reduce the chance of associating with bacteria and viruses and to achieve a further sterilizing effect. In order to eliminate such inconvenience, it is necessary to increase the fan capacity in accordance with the volume of the room and further increase the number of disinfecting ion generating elements.

  However, as a practical measure, there is a limit to the fan capacity and the number of installed sterilization ion generating elements due to the sound in the room and the wind speed of the air flow, and thus it is difficult to eliminate the above inconvenience. Therefore, a sterilization barrier that prevents new bacteria and viruses from entering the room by entering and leaving the room is created, and the air flow in the room is not disturbed by the entry and exit of the person. Although it is better to keep the sterilization effect at all times, there is no such thing so far.

  Therefore, the present invention has been made in view of the above circumstances, and even if the fan capacity is small and the number of installed sterilization ion generating elements is small, the movement of bacteria and viruses from the inside and outside of the room is prevented. It is an object of the present invention to provide a method for producing a sterilization barrier capable of maintaining a good hygiene state and an apparatus therefor.

The method of the present invention as claimed in claim 1 is a divided air flow containing sterilization ions that mixes after discharging sterilization ions into an air flow, and then rectifies and separates the entrance from the inside of the entrance that leads to the inside and outside of a certain space. Therefore, the disinfection ions are uniformly dispersed and the opportunity to associate with the fungi becomes uniform, and the fungi are killed more effectively. In this case, the sterilization ion-containing fragmented air flow always passes, so that the sterilization ions kill the fungus, stop the movement of the fungus at the entrance and exit of a certain space, since shunted hit the floor in a certain space, I Do to spraying sterilization ions to a certain space outside in and near the entrance some space, some space outside in these certain space and near doorway It is in Make killing kind. Therefore, even if the fan capacity is small and the number of the sterilization ion generating elements is small, there is an effect that it is possible to prevent the movement of fungi from the entrance and exit and maintain a good hygiene condition in the room.

In the invention method according to claim 2, since there are a plurality of sterilization ion-containing divided air streams described above, when fungi move through the entrance / exit of a certain divided space , a plurality of sterilization ion-containing divided air streams and a space between them. will be of always passing through the sterilization ion spray zone, to kill fungi at the inlet and outlet ports of the one space divided in a more complete form, stopping the movement of it. Therefore, the above-described effect can be obtained more reliably.

When the air blower is operated, air enters from the suction port and becomes an air flow by the air blower. The air flow is turbulent by the turbulent flow plate, and the turbulent flow from the sterilization ion generator with releasing sterilization ions, the current plate rectifies the turbulence is discharged from the discharge port makes it disinfecting ion-containing split air stream to separate from the inside of the doorway leading to a certain space and out the entrance to the boundary, this certain When fungi move in and out of a space , they must pass through a sterilized ion-containing fragmented air flow. At that time, the fungi are killed by the disinfecting ions to stop the movement of the fungi at the entrance and exit of a certain space. bacterial ion-containing split air stream is diverted hit the floor in a certain space, will be sprayed sterilization ions within a certain space and a certain space outside near the entrance, these certain space and doorway Nearby Make kill fungi in the space outside of that.

Therefore, in addition to being able to efficiently execute the above-described inventive method, there is an effect of adding an air cleaning function for cleaning the suction air from the suction port.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing a sterilization barrier creating apparatus for realizing the method of the present invention, FIG. 2 is a cross-sectional view of the sterilization barrier creating apparatus, and FIG. 3 is a perspective view showing a state in which the sterilization barrier creating apparatus is provided at an indoor entrance. FIG. 4 is a cross-sectional view showing the operation of the sterilization barrier creating apparatus in a state where the door of the entrance / exit of FIG. 3 is opened. In the drawings, 1 denotes a sterilization barrier creating apparatus, the sterilization barrier creating device 1, the device in the body 2, the suction port 3 and the entrance 21 from the inside of the doorway 21 of a certain spatial structures 20 leading to the inside and outside and a discharge port 5 out of air stream 4 for dividing the boundary, disposed blower 6 to the apparatus the body 2 of between outlet 5 and these suction port 3, the discharge opening 5 and the blower 6 device to the body 2 provided with a sterilization ion generator 7 between, provided with a turbulence plate 14 on the upstream side of the sterilization ion generator 7, the rectifying plate 15 is provided on the outlet 5 of the downstream side The air flow from the blower 6 is made turbulent by the turbulent flow plate 14 and the sterilization ion R from the sterilization ion generator 7 is released, and is rectified by the rectifying plate 15 and discharged from the discharge port 5. The sterilized ion-containing divided air flow 8 is used.

The apparatus Main body 2 is a flat box body, the suction opening 3 is provided in an upper portion of the positive side 2a, the discharge port 5 is provided on the bottom surface 2b. The present somatic 2 is separated by the partition plates 10 is divided into a suction side chamber 11 and the sterilization ion supply chamber 12. The blower 6 is disposed across the suction side chamber 11 and the sterilization ion supply chamber 12. Further, the sterilization ion generator 7 is attached to the suction side chamber 11 of the partition plate 10, and the discharge part 7a of the sterilization ion R faces the sterilization ion supply chamber 12 side. A mixer 13 is attached to the suction side chamber 11 between the blower 6 and the sterilization ion generator 7. The mixer 13 is not particularly limited as long as it can be efficiently mixed without impairing the function of the sterilization ion R. In this example, two turbulent flow plates 14 are provided. When the turbulent flow is caused in the air flow 4 from the blower 6 and the sterilization ions R are released from the discharge portion 7a, the turbulent flow plate 14 is efficiently removed. The fungus ion R is mixed.

Device outlet 5 of the body 2 is to form and discharge the decontamination ion-containing split air stream 8, since the sterilization ion-containing split air stream 8 is intended to divide the doorway 41 of a certain space, divided A sufficient reach must be provided to the sterilized ion-containing fragmented air flow 8. Therefore, by arranging a flow straightening plate 15 in parallel inside the discharge port 5 and providing a run-up space for rectifying the sterilized ion-containing divided air flow 8, it is possible to obtain a reachable distance required for separation. ing.

  The air blower 6 is not particularly limited as long as it has a necessary air volume and air pressure for obtaining the sterilized ion-containing divided air flow 8, but a once-through air blower is better for dividing a wide space.

  The sterilization ion generator 7 is not particularly limited as long as it generates sterilization ions R and can kill bacteria and viruses floating in the air while ensuring safety to the human body. . In addition to this, the sterilization ion generator 7 capable of killing bacteria and viruses attached to humans and objects is even better.

As the sterilization ion generator 7, for example, a dielectric is sandwiched between both ion generation electrodes, and an alternating current having a voltage of 1.5 KV to 3.0 KV and a frequency of 15 KHz to 2.5 KHz is applied to one of the ion generation electrodes, There is a type in which the other ion generating electrode is grounded. In this embodiment, each ion generation electrode has a structure of H ⁺ (H ₂ O) _m that is a positive ion or O ₂ ⁻ (H ₂ O) _n (m and n are integers) that is a negative ion. Things occur. These positive and negative ions constitute a sterilization ion R in a cluster shape. This sterilization ion R surrounds bacteria and viruses floating in the air, and reacts with these positive and negative cluster ions on the surface of these bacteria and viruses to generate hydroxyl radicals OH or hydrogen peroxide H _2. O ₂ is produced, and these inactivate or kill bacteria and viruses.

  In addition, when the sterilization ion generator 7 applies a high voltage of 6.0 KV to water, for example, the water obtains a large energy and surpasses the surface tension to cause Rayleigh splitting (electrostatic atomization) one after another, and 20 nm ( It may be in a form in which ultrafine ions, which are sterilization ions R wrapped in water before and after nanometers, are generated. The ultrafine ions generated in this form last for a long time because they contain hydroxy radicals / OH and are surrounded by water, encapsulate the bacteria and viruses, and kill the bacteria and viruses by the hydroxy radicals / OH. In addition, sterilization ions R in any of the above forms can also decompose odor components in addition to bacteria and viruses.

  The sterilization barrier creating apparatus 1 configured as described above is installed at a position that divides a certain space, for example, on the wall or ceiling above the room 23 side of the entrance / exit 21 of the building 20 as shown in FIG. The A door 22 is installed at the entrance / exit 21 and is uniquely divided into an indoor 23 and an outdoor 24 in the building 20 by the door 22. However, when the door 22 is opened while the sterilization barrier creating apparatus 1 is in an activated state, the sterilization barrier containing apparatus 1 continues to be divided into the indoor 23 and the outdoor 24 by the sterilization ion-containing divided air flow 8 from the discharge port 5 of the apparatus 1. And when this sterilized ion-containing divided air flow 8 hits the floor 25, as shown in FIG. 4, it is divided into the indoor 23 and the outdoor 24, the diverted flow 8a on the indoor 23 side contributes to the sterilization of the indoor 23, The branch flow 8b on the outdoor 24 side contributes to sterilization in the vicinity of the indoor 23 in the outdoor 24.

  And since the substance including a person and gas enters / exits from any direction of the room | chamber 23 and the outdoor 24, it will pass through the entrance / exit 21 by all means, Therefore Bactericidal ion from the discharge port 5 of the sterilization barrier preparation apparatus 1 When the contained divided air flow 8 is bathed, the sterilization ions R associate with the bacteria and viruses present in the substance passing through the entrance 21 and inactivate them. Therefore, the sterilization ion-containing divided air flow 8 by the sterilization barrier creating apparatus 1 constitutes a sterilization barrier. On the other hand, when the door 22 is closed, the sterilized ion-containing divided air flow 8 from the discharge port 5 is blown down along the door 22 and hits the floor 25 as shown in FIG. The bacteria and viruses present in the room 23 are killed. The door 22 is not particularly limited as long as the doorway 21 can be freely closed or opened, and may be automatic, manual, open door type, sliding door type, or rotary type. Don't get caught up in

  In addition, as shown in FIG. 5, for example, as shown in FIG. good. Therefore, the sterilization ion-containing fragmented air flow 8A from the discharge port 5A of one sterilization barrier creation device 1A, and the sterilization ion-containing fragmentation air flow 8B from the discharge port 5B of the other sterilization barrier creation device 1B, A sterilization barrier chamber 28 surrounded by is formed. Both the sterilized ion-containing divided air flows 8A and 8B hit the corridor 29, and become a diversion flow 28a and 28b on the sterilization barrier chamber 28 side and an outer diversion flow 28c and 28d. The diversion flows 28 a and 28 b on the side of the sterilization barrier chamber 28 contribute to sterilization in the sterilization barrier chamber 28, and sterilization ions R are suspended in the sterilization barrier chamber 28, and pass through the sterilization barrier chamber 28. The sterilization ion R associates with bacteria and viruses present in the substance and inactivates them. On the other hand, the outer diversions 28 c and 28 d contribute to sterilization in the vicinity outside the sterilization barrier chamber 28.

  And from any direction of the sterilization barrier creation devices 1A and 1B, when substances including people and gas pass through the passage 26, the sterilization ion-containing separated air flow 8A from the sterilization barrier creation devices 1A and 1B and 8B will surely be taken, and also the sterilization barrier room 28 will surely pass. Therefore, the bacteria and viruses existing in the substance passing through the passage 26, that is, the fungi float in the sterilization ion R contained in the sterilization ion-containing divided air streams 8A and 8B and the sterilization barrier chamber 28. It associates with the sterilization ion R and is inactivated. Accordingly, the substances passing through the passage 26 are killed by the sterilization barrier containing the sterilization ion-containing separated air flows 8A and 8B and the sterilization barrier chamber 28. Moreover, these sterilization barriers are convenient because they can pass through other than fungi and have good visibility.

Next, a method for creating a sterilization barrier will be described using the sterilization barrier creating apparatus 1 in Examples 1 and 2 having the above-described configuration.
First, in the case of Example 1, the sterilization barrier creation apparatus 1 suitable for the height and width size of the entrance / exit 21 of the room 23 in the building 20 is selected, and this is used as the wall above the entrance / exit 21 on the room 23 side. Or install it on the ceiling. Next, when the operation of the sterilization barrier creating apparatus 1 is started, air is sucked from the suction port 3 by the blower 6 to form an air flow 4, and turbulent flow is generated by the two turbulent flow plates 14 of the mixer 13. Since the sterilization ions R are released from the sterilization ion generator 7, the turbulent air flow 4 is efficiently mixed. The air flow 4 in a turbulent state containing the sterilizing ions R and sufficiently mixed is rectified by the rectifying plate 15 and discharged from the discharge port 5 to become the sterilized ion-containing divided air flow 8.

  As shown in FIG. 3, when the door 22 of the entrance / exit 21 of the room 23 is closed, the sterilized ion-containing divided air flow 8 is blown down along the door 22 and hits the floor 25, and all flows into the room 23. The bacteria and viruses present in the room 23 are killed. As shown in FIG. 4, when the door 22 is open, the disinfecting ion-containing divided air flow 8 hits the floor 25 to become a divided flow 8 a on the indoor 23 side and a divided flow 8 b on the outdoor 24 side, and the indoor 23 and the vicinity thereof. This sterilization ion-containing divided air flow 8 contributes to the sterilization of the outdoor 24 and divides the indoor 23 and the outdoor 24 in an airflow manner even when the door 22 is open. Even if there is a substance that breaks the air flow 8 that has been sterilized and contains sterilized ions that are divided, the bacteria that accompany this substance are killed by the sterilizing ions R, and the sterilized ions that contain the sterilized ions are separated. The air flow 8 becomes a sterilization barrier and virtually cannot pass.

  Next, in the case of Example 2, as shown in FIG. 5, when two rows of the sterilization barrier creating apparatuses 1 </ b> A and 1 </ b> B are installed at intervals on the ceiling 27 of the passage 26, the removal of FIG. 4 described above is performed. It is the same as having two bacteria barrier production apparatuses 1, and furthermore, a space extending between the bacteria removal barrier production apparatuses 1 </ b> A and 1 </ b> B constitutes the bacteria removal barrier chamber 28. Therefore, the passage 26 is separated in an air flow by the sterilization ion-containing separated air flows 8A and 8B and the sterilization barrier chamber 28 from the two sterilization barrier creation apparatuses 1A and 1B. Even if there is a substance that breaks through the sterilization ion-containing separated air flows 8A and 8B and the sterilization barrier chamber 28 that are separated by the air current, and there is a substance that tries to pass through, there are fungi attached to this substance. The sterilization ions R are killed, and the sterilization ion-containing separated air flows 8A and 8B and the sterilization barrier chamber 28 become sterilization barriers and cannot pass through in effect.

The sterilization barrier generating apparatus 31, as shown in FIGS. 6 and 7, apparatus and the body 32 to the suction port 33 and a discharge port 34, The present body between these suction ports 33 and the discharge port 34 32 A clean filter 35 and a blower 36 are arranged in the air cleaner 30 to constitute the air cleaner 30, and the sterilization ion generator 7 </ b> A described above and the clean filter between the clean filter 35 and the suction port 33 of the air cleaner 30. formed by providing a sterilization ion generator 7B and 7C the device the body 32 between the 35 and the outlet 34. Sterilization ion generator 7A is a sterilization ions R released into the suction air S from the suction port 33, by removing the fungus present in the suction air S, to hold the device the body 32 to the sterilization conditions At the same time, the sterilization ion generators 7B and 7C release the sterilization ions R to the purified air from the blower 36, and are further emitted from the discharge port 34 and the outlet 47 described later to contribute to sterilization.

The above air cleaner 30, more specifically the sitting table plate supporting portions 40 provided with positioning the said suction port 33 on one wide side 32a of the device the body 32 which forms a flat box, the sitting table plate supporting the sitting table 41 by use support 40, by positioning the outlet 34 between the two panel board 42 is provided with the panel plate 42 on both sides of the other wide side 32b, furthermore, both of the apparatus main body 32 the narrow side surfaces 32c and the upper surface 32d, provided outlet 47 to form a disinfecting ion-containing split air stream 46 to divide the chamber 43 in cooperation with the panel board 42 to the suction port side space 44 and a discharge port side space 45, device the cleaning filter 35 and the blower 36 to the body 32 is positioned between the outlet 34 and the outlet 47 and the suction port 33 becomes provided with an exhaust amount of cleaning air from the discharge port 34 At least, it is set to be larger than the external air entrainment air amount Q from the outside of the suction port side space 44, and the suction port side space 44 is made into a negative pressure state and is set as a smoking space 44A, and the discharge port side space 45 is set as a non-smoking space 45A.

The apparatus main body 32 is provided with a caster 50 on its lower surface, and a caster 51 and an adjuster 52 are also provided on the sitting table 41 so as to be freely movable. Further, an ashtray is placed on the sitting table 41, By arranging a chair (both not shown) and the like around, the suction port side space 44 in the room 43 can be easily made into a smoking space 44A where the sitting table 41 is installed. In FIG. 6, 53 is an operation panel, and 54 is a sensor such as a human sensor or a smoke sensor.

The inside of the apparatus main body 32 is divided into a suction cleaning treatment chamber 61 and an air distribution chamber 62 by a vertical partition plate 60, and both chambers 61, 62 are connected by a lower communication port 63. The suction cleaning processing chamber 61 sucks and purifies purple smoke together with the suction air S from the suction port 33, and the air distribution chamber 62 divides the cleaning air into the exhaust port 34 and the blowout port 47. Then, the wide side surface 32a side of the suction cleaning treatment chamber 61 is located the suction port 33, further wherein the sitting table plate supporting portion 40 is positioned in the middle of the suction port 33, The present body divided in the vertical partition plate 60 side The sterilization ion generator 7A for performing bacteria is attached. A unit 64 that houses the cleaning filter 35 and the blower 36 is built in the lower portion of the suction cleaning processing chamber 61. In the air distribution chamber 62, the exhaust port 34 is located at the lower part, and the air outlet 47 is located from the upper surface and the upper part of the side surface to the lower part.

  As the sterilization ion generators 7A, 7B, and 7C, any one of the two types of sterilization ion generators 7 described above may be selected. The sterilization ions R from the sterilization ion generator 7A for in-machine sterilization are uniformly released to the suction air S from the suction port 33, and are associated with the bacteria and viruses present in the suction air S. It is necessary to make it. For this purpose, the installation location of the sterilization ion generator 7 is important. In this example, as described above, it is attached to the vertical partition plate 60 slightly above the suction port 33 in the upper portion of the suction cleaning processing chamber 61. In any case, the place where the sterilization ion generator 7 </ b> A is installed is an arbitrary place in the suction cleaning processing chamber 61 around the suction port 33 or upstream of the unit 64. Further, a mixer for mixing the sterilization ions R and the suction air S is provided on the downstream side of the sterilization ion generator 7A. For example, the turbulent flow plate is used as a mixer in the suction cleaning processing chamber 61 upstream of the unit 64. The turbulent flow is caused in the suction air S so that the sterilization ions R can be easily mixed with the suction air S, and the sterilization ions R are spread throughout the suction air S. You may make it remove the microbe and virus which exist.

  The unit 64 is divided by a partition plate 65, and the cleaning filter 35 disposed at the upper portion is not particularly limited as long as it clears a certain performance, but in this example, it is attached to the lower surface of the inlet 66. A prefilter 67 that removes relatively large particles in the contaminated air, an electric dust collector 68 that removes fine particles after passing through the prefilter 67, and a deodorizer that is attached to the upper surface of the communication port 69 of the partition plate 65 and removes odor components. The filter 70 and the three-part configuration. Instead of the electrostatic precipitator 68, a high-performance electrostatic filter having a deodorizing function may be used. Further, the lower fan 66 in the unit 64 is not particularly limited as long as necessary capacity and pressure conditions are satisfied.

The exhaust port 34 below the air distribution chamber 62 is configured by a group of small circular holes, and exhausts a part of the cleaning air by the cleaning filter 35 to the non-smoking space 45A side. On the other hand, the air outlet 47 includes a side air outlet 47a provided on both narrow side surfaces 32c of the apparatus main body 32 and an upper surface air outlet 47b provided on the upper surface 32d. The remainder of the air is blown out to form a sterilized ion-containing fragmented air flow 46. And it is necessary to set the exhaust amount of the cleaning air from the exhaust port 34 to be larger than the external entrainment air amount Q from the outside of the smoking space 44A. In addition, the blowout of the disinfecting ion-containing fragmented air flow 46 from the side surface outlet 47a and the upper surface outlet 47b is set so as to maintain the wind speed and air volume so that the purple smoke of the cigarette in the smoking space 44A does not go outside. There is a need to.

  Therefore, the cleaning air by the cleaning filter 35 in the unit 64 exits from the outlet 71 and once enters the air distribution chamber 62 from the communication port 63, and from here the opening area ratio of the exhaust port 34 and the outlet 47 is predetermined. A part of the cleaning air set larger than the above-described external entrainment air amount Q comes out from the exhaust port 34, and the inside of the smoking space 44A is brought into a negative pressure state. Then, the remaining portion of the cleaning air exits from the blowout port 47 to form a sterilized ion-containing fragmented air flow 46, which is divided into a negative pressure suction port side space 44 and an exhaust port side space 45 in an airflow control manner. Can do.

Further, the disinfectant ion generator 7B and 7C, may be provided to the device the body 32 between the outlet 34 and the cleaning filter 35. In this example, the sterilization ion generator 7B is in front of the communication port 63, and the sterilization ion generator 7C is attached to the vertical partition plate 60 on the air distribution chamber 62 side downstream of the upper surface outlet 47b. . For this reason, in addition to removing the bacteria and viruses present in the suction air S, the sterilization ions R from the sterilization ion generators 7B and 7C are also released into the clean air from the blowout port 47, and the clean air of air to release the device the body 32 outside topped with eradication ions R, may be a disinfecting ion-containing split air stream 46 as described above. Therefore, this disinfecting ion-containing fragmented air flow 46 is the sterilization barrier already described, and flows to the suction port side space 44 side in a negative pressure state to sterilize the inside of the suction port side space 44. Furthermore, since the sterilization ion R exists in the cleaning air from the discharge port 34, the discharge port side space 45 is also sterilized.

  Next, a method of dividing one corner of the room 43 into the smoking space 44A and the non-smoking space 45A using the sterilization barrier creating apparatus 31 having the air purifier 30 configured as described above will be described. FIG. 9 shows the simplest method of dividing the room 43 into a smoking space 44A and a non-smoking space 45A. Since one corner of the room 43 is surrounded by walls 72, 73, and 74 that intersect at right angles, the sterilization barrier creating device 31 is installed so as to be partitioned by the panel plate 42, thereby creating a rectangular smoking space 45A. At this time, the sterilization barrier creating apparatus 31 is installed so that the suction port 33 faces the walls 72, 73, 74 side and the exhaust port 34 faces the side without the walls 72, 73, 74.

  Then, when the blower 36 of the sterilization barrier creating device 31 is operated, air blows out from the air outlet 47 to form a sterilized ion-containing fragmented air flow 46, and the indoor 43 is separated from the smoking space 44A and non-smoking with this as a boundary. This is divided into a space 45A. The purple smoke from the smoker in the smoking space 44A is immediately captured without affecting other smokers, and sucked into the suction port 33 together with air to become the suction air S, and the sterilization ion generator 7A The sterilization ions R from the worms are released uniformly, associate with the bacteria and viruses present in the suction air S, and kill these bacteria and viruses, and are cleaned by the cleaning filter 35 in that state. It becomes purified air, and sterilization ions R from the sterilization ion generator 7 </ b> B are also added, and once enters the air distribution chamber 62 through the communication port 63. A part of the cleaning air from the air distribution chamber 62 comes out from the exhaust port 34 to sterilize the discharge port side space 45 and make the inside of the suction port side space 44 into a negative pressure state. Furthermore, the remainder of the cleaning air blows out from the outlet 47 to form a sterilized ion-containing fragmented air flow 46 by the cleaning air, which contains the sterilizing ions R from the sterilizing ion generators 7B and 7C. To sterilize. Therefore, no bacteria or viruses are alive on the clean filter 35, and the smoking space 44A and the non-smoking space 45A are also comfortable spaces because the bacteria and viruses are reduced or killed.

  On the other hand, the purple smoke that has not been captured drifts in the smoking space 44A, but the amount of air discharged from the exhaust port 34 is greater than the amount of external entrained air Q due to the sterilized ion-containing divided air flow 46 from outside the smoking space 44A. Since the inside of the smoking space 44A is in a negative pressure state, the purple smoke drifting in the smoking space 44A does not go into the non-smoking space 45A, and finally enters the suction port 33 as described above. In the same manner, the purified air is cleaned and discharged as the purified air from the exhaust port 34 to the non-smoking space 45A, or the sterilized ion-containing fragmented air flow 46 from the air outlet 47 again. And, when the cleaning filter 35 is replaced, bacteria and viruses are killed, so it is not necessary to take a protection system.
