The present invention relates to a technique for detoxifying bacteria and viruses floating in the air.

Some air purifiers detoxify bacteria and viruses floating in the air by taking in air inside the device and irradiating it with ultraviolet rays.

In addition, in a device that irradiates ultraviolet rays to detoxify bacteria and viruses, when air is taken into a cylindrical member, it is taken in as a vortex (a flow that spirals inside the cylinder), and the air taken in is taken in. A device that irradiates ultraviolet rays is known (for example, Patent Document 1).

In addition, a module is known that can be applied to various member shapes by arranging a plurality of thin tubes that irradiate ultraviolet rays side by side to form a sheet-like surface structure and flexibly deforming the thin tubes such as bending and bending. For example, Patent Document 2).

Then, in the second and subsequent embodiments, the attachments will be focused on, and variations of the attachments will be specifically presented and described.

(First Embodiment)
<Overall configuration>
FIG. 1A is a perspective view illustrating the overall configuration of the air purification system of the present embodiment, and FIG. 1B is a diagram in which an air flow is added by a broken line arrow. Regarding the first embodiment, the directions of the X-axis, the Y-axis, and the Z-axis shown in each drawing are common to each drawing.

The air purifying system 300 includes an upper cap 210, a cylindrical member 220, and a lower cap 230, and is provided with an air purifying device 200 in a posture in which the longitudinal direction of the cylindrical member 220 is in the vertical direction (= Z-axis direction, gravity direction). And one or more frames provided in a posture in which one end is connected to the upper cap 210 of the air purifier 200 and the longitudinal direction is the horizontal direction (here, the X-axis direction, but the Y-axis direction may be used). It has a member 100 (long member, horizontal attachment).

One end of the frame member 100 is connected to the opening of the upper cap 210 so as to allow ventilation, but the other end on the side not connected to the upper cap 210 is a resin end cap. It is covered with 150.

The outline of the operation of the air purification system 300 will be described with reference to FIG. 1 (B). In the air purification system 300, the fan 240 (described later) housed in the lower cap 230 operates to take in air into the frame member 100. The taken-in air passes through the inside of the frame member 100 and flows toward the air purifier 200.

The air that has flowed into the air purifying device 200 through the upper cap 210 travels spirally while swirling along the inner wall surface in the cylindrical member 220 by the guide blade 250 described later. An ultraviolet lamp 260 (described later) is provided in the cylindrical member 220. The ultraviolet lamp 260 (purifier) irradiates ultraviolet rays to detoxify bacteria and viruses contained in the air inside the cylindrical member 220. Hereinafter, bacteria and viruses are collectively referred to as "pathogens".

The air in the cylindrical member 220 after being detoxified is discharged from the opening 234 of the lower cap 230. The opening 234 exhausts the detoxified air in a direction parallel to the extending direction (X-axis direction) of the frame member 100 (X-axis direction).

<Structure of frame member>
Subsequently, the frame member 100 will be described. FIG. 2A is a perspective view showing a state in which three frame members 100 are connected, and FIG. 2B is a perspective view showing one frame member 100. Further, FIG. 2C is a cross-sectional view of the frame member 100. In FIG. 2A, the traveling direction of air is indicated by a broken line arrow, and in FIG. 2B, the plate member 140 is not shown. Further, in the following drawings, holes and members provided at a plurality of locations may be partially designated with reference numerals.

The frame member 100 may have a one-module configuration shown in FIG. 2 (B) or a plurality of connected frames as shown in FIG. 2 (A). In either the configuration of one module or a plurality of modules, one end is opened (open end 160 in the figure), and the other end is covered with an end cap 150 to form a long member. Further, the open end portion 160 is connected to the upper cap 210 of the air purifier 200 so as to allow ventilation so that air does not escape to the outside.

The frame member 100 is made of aluminum, and one or a plurality of suction slits 130, which are holes for taking in outside air into the member, are provided side by side in the frame body 120 (see FIG. 2B). Although the suction slits 130 are described here as being provided on both side surfaces of the frame body 120, the embodiment is not limited to this, and the upper surface of the frame body 120 or the like may be used.

As shown in FIG. 2C, the frame body 120 of the frame member 100 has a configuration in which each member of the upper member 120A and the lower member 120B is connected at the position shown by the broken line circle 120C. By connecting the upper member 120A and the lower member 120B, a cavity for ventilation in the long direction is formed inside the frame member 100. In the present embodiment, this cavity is partitioned by a plate member 140. Thereby, the ventilation between the suction slits 130 provided on both side surfaces of the frame body 120 can be blocked (the air taken in by the suction slits 130 provided on one side surface is provided on the other side surface). It can be blocked from coming out of the suction slit 130).

On the upper surface of the frame body 120, a panel support portion 110 for erecting a panel 123 (see FIG. 12) described later is provided. The panel support portion 110 is provided with a hole 110A through which a biz for fixing the panel 123 is passed. By making the panel erected in this way, the frame member 100 can also function as a partition for partitioning the table (see FIG. 12).

<Structure of air purifier>
Next, the configuration of the air purifier 200 will be described.

FIG. 3A is a perspective view when the air purifier 200 is visually recognized from above, and FIG. 3B is a perspective view when the air purifier 200 is visually recognized from below. An exploded view of the air purifier 200 is shown in FIG.

<Structure of upper cap>
The upper cap 210 of the air purifier 200 is a member for protecting an impact from the outside and the like. Further, by making the upper cap 210 opaque, it is possible to block the ultraviolet rays irradiated inside the cylindrical member 220 from leaking to the outside.

The upper cap 210 covers and protects the guide blade 250 and the base 261 of the ultraviolet lamp 260. A near perspective view of the upper cap 210 is shown in FIG. 5 (A), and a side view is shown in FIG. 5 (B). FIG. 5C shows a front view of the upper cap 210 when the upper cap 210 is visually recognized from the opening 211.

The opening 211 is a portion that is airtightly connected to the opening end 160 of the frame member 100, and allows air taken into the frame member 100 to flow in. The opening 211 is connected to the opening end 160 of the frame member 100 by being biz-fastened using the hole 214.

The hole 212 is a hole for fastening a biz for fixing the guide blade 250 to the upper cap 210. The L-shaped groove 213 is for fixing the upper cap 210 to the cylindrical member 220. The upper cap 210 and the cylindrical member 220 are fixed by engaging the L-shaped groove 213 with the biz inserted into the hole 220A (see FIG. 4A) provided in the side wall of the cylindrical member 220. do.

<Structure of guide blade>
The guide blade 250 shown in FIG. 4 is provided between the frame member 100 and the cylindrical member 220 on the air flow path, and the air flowing from the frame member 100 spirals while swirling in the cylindrical member 220. It is a member that directs the air so that it progresses.

A near perspective view of the guide blade 250 is shown in FIG. 6 (A), and a perspective view showing a state of being fixed to the upper cap 210 is shown in FIG. 6 (B). Further, FIG. 6C shows an air flow direction indicated by a broken line arrow with respect to FIG. 6A, and FIG. 6D shows a top view of the guide blade 250. In FIG. 6D, the flow of the entire air is illustrated by a broken line arrow.

The guide blade 250 has a plurality of blades 251 provided radially from the central portion 252. In the present embodiment, the central portion 252 is provided so that the center is on the extension line of the cylindrical axis of the cylindrical member 220.

The plurality of blades 251 are provided so as to be inclined with respect to the horizontal plane (XY plane). Therefore, a gap 253 is formed in the vertical direction (Z-axis direction) between the tip P1 in the circumferential direction of a certain blade 251 and the rear end P2 in the circumferential direction of the blade 251 provided on the side of the tip P1 of the blade 251. ..

The air flowing from the frame member 100 toward the guide blade 250 hits the inclined surface of the blade 251 and travels along the inclined surface as shown by the broken line arrow in FIG. 6 (C). The air guided in this way enters the inside of the cylindrical member 220 through the gap 253 and touches the inner side wall of the cylindrical member 220. The air that touches the inner side wall of the cylindrical member 220 tends to maintain contact with the inner side wall due to the Coanda effect and centrifugal force, and while maintaining this contact tendency, the intake operation of the fan 240 causes the exhaust direction (Z-axis). Flows downward). As a result, the air taken into the cylindrical member 220 spirals downward while swirling, as shown by the broken line arrow in FIG. 6 (D) (cylindrical member in FIG. 1 (B)). See also the dashed arrow in 220).

In this way, in the cylindrical member 220, by allowing the air to flow spirally while swirling, it is possible to increase the moving distance compared to letting the air go straight from top to bottom, and the ultraviolet rays from the ultraviolet lamp 260 can be increased accordingly. The irradiation time can be lengthened.

<Structure of UV lamp>
The ultraviolet lamp 260 is a light emitting body that irradiates ultraviolet rays provided inside the cylindrical member 220, and turns on / off according to the operation of a switch (not shown). The ultraviolet lamp 260 is a purification device that emits light inside the cylindrical member 220 to detoxify pathogens contained in the air taken into the cylindrical member 220. In the present embodiment, the ultraviolet lamp 260 irradiates ultraviolet rays having a wavelength of around 253.7 nm, which has high bactericidal activity. The wavelength of the emitted light beam is not limited to this.

Although not shown, a socket corresponding to the base 261 of the ultraviolet lamp 260 is provided directly under the central portion 252 of the guide blade 250, and by inserting the base 261 into this socket, the ultraviolet lamp 260 is provided. Is located directly below the central portion 252 of the guide blade 250. On the other hand, since the air is spirally flowed along the inner side wall of the cylindrical member 220 due to the guidance by the guide blade 250, the air is sparse just below the central portion 252 of the guide blade 250 (near the cylindrical axis of the cylindrical member 220). It becomes a state. In the present embodiment, by providing the ultraviolet lamp 260 in this sparse space, it is possible to reduce the disturbance of the air flow due to the ultraviolet lamp 260.

<Structure of cylindrical member>
The cylindrical member 220 of the present embodiment is opaque so that the ultraviolet rays irradiated inside do not leak to the outside. Further, the cylindrical member 220 may be configured such that a mirror-reflecting film is attached to the inner side wall of the cylinder. Further, the inner side wall of the cylinder (when the specular reflection film is attached to the inner side wall of the cylinder, the top of the film) may be coated with a photocatalyst such as titanium oxide.

By specularly reflecting the inside of the cylinder, the cylindrical member 220 can reflect the ultraviolet rays emitted from the ultraviolet lamp 260 and amplify the amount of light. Further, due to the guidance of the air by the guide blade 250, the air on the inner side wall side of the cylindrical member 220 becomes denser than the central portion, and the chance of the air coming into contact with the inner side wall of the cylindrical member 220 increases accordingly. Therefore, by coating the inner side wall of the cylindrical member 220 with a photocatalyst, the pathogen can be further detoxified by the oxidative action generated by the photocatalyst and ultraviolet rays.

<Structure of lower cap>
Like the upper cap 210, the lower cap 230 is a member for protecting an impact from the outside. Further, by making the lower cap 230 opaque, it is possible to block the ultraviolet rays irradiated inside the cylindrical member 220 from leaking to the outside.

The lower cap 230 is a member that houses and protects the fan 240 inside. A near perspective view of the lower cap 230 is shown in FIG. 7 (A), and a top view of the lower cap 230 when viewed from the opening 233 is shown in FIG. 7 (B). A front view of the lower cap 230 viewed from the opening 234 is shown in FIG. 7 (C).

By inserting the cylindrical member 220 into the opening 233 of the lower cap 230, the lower cap 230 and the cylindrical member 220 are connected to each other. Further, the lower cap 230 and the cylindrical member 220 are fixed by matching the positions of the hole 231 of the lower cap 230 and the hole 220B (see FIG. 4) on the cylindrical member 220 side and passing the biz. The direction of the exhaust port 243 (see FIG. 8) of the fan 240, that is, the direction of the exhaust of the air purifier 200 can be adjusted depending on which of the holes 231 of the lower cap 230 is used to fix the cylindrical member 220. can.

The hole 232 is a hole through which a biz for fixing the fan 240 to the lower cap 230 is passed. The lower cap 230 and the fan 240 are fixed so that the exhaust port 243 (see FIG. 8) of the fan 240 and the opening 234 are aligned with each other.

<Fan configuration>
FIG. 8A is a near-view view when the fan 240 is visually recognized from above, and FIG. 8B is a top view when the fan 240 is visually recognized from the shaft 241A. Further, FIG. 8C is a perspective view of the vicinity when the fan 240 is visually recognized from below. In FIG. 8A, the direction of air blown by the fan 240 is indicated by a broken line arrow.

The fan 240 has a rotary blade 241 that rotates on a shaft 241A, and when the rotary blade 241 rotates, outside air is taken in from the frame member 100, and the upper cap 210, the guide blade 250, the cylindrical member 220, and the lower cap 230 are taken in. A flow path through which air flows is formed in the order of. That is, the fan 240 is a blower that takes in air from one end (upper cap 210 side) of the cylindrical member 220 into the inside of the cylindrical member 220 and blows the taken in air toward the other end of the cylindrical member 220 (lower cap 230 side). Functions as. The air after being taken into the cylindrical member 220 and detoxified by the fan 240 is discharged from the exhaust port 243.

The hole 242 is a hole for being biz-fastened to the hole 232 of the lower cap 230, and the fan 240 is fixed to the lower cap 230 by this biz-fastening.

<Structure of inclined member>
In the air purifying device 200 of the present embodiment, in addition to the above-mentioned configuration, the inclined member 270 is provided on the end side (connecting portion between the cylindrical member 220 and the lower cap 230) of the discharge port of the cylindrical member 220. 9 (A) is a near perspective view when the inclined member 270 of the present embodiment is visually recognized from above, and FIG. 9 (B) is a bottom view. 9 (C) is a perspective view when the inclined member 270 is visually recognized from below, and FIG. 9 (D) is a diagram showing a state in which the inclined surface 272 of the inclined member 270 is covered with a sheet-shaped filter. Note that FIG. 9A also shows the cylindrical axis C of the cylindrical member 220.

The inclined member 270 is a member for providing an inclined surface 272 on the exhaust port end side of the cylindrical member 220. The inclined surface 272 is in an inclined posture in one direction in a state where the inner side wall of the cylindrical member 220 and the side surface 273 of the inclined member 270 are in contact with each other and attached. Further, a ventilation hole 271 is provided in the central portion of the inclined surface 272, and when the inclined member 270 is attached to the cylindrical member 220, it is on the axis of the cylindrical shaft C of the cylindrical member 220 (the central portion of the inclined surface 272). The ventilation hole 271 is located.

Actually, as shown in FIG. 9D, the inclined surface 272 of the inclined member 270 is completely covered with the sheet-shaped filter 275 (the ventilation hole 271 is also covered). The filter 275 may be configured by laminating a plurality of sheets of cloth or the like. Further, in order to easily replace the used filter 275 with a new one, the side wall of the cylindrical member 220 on the exhaust port end side may be configured to be openable. In the present embodiment, the inclined member 270 is fixed to the cylindrical member 220 and the lower cap 230, but the inclined member 270 is fixed to the cylindrical member 220 and the lower cap 230 so that the inclined member 270 can be easily replaced. It does not have to be.

10 and 11 are views for explaining the effect of providing the inclined member 270. FIG. 10A is a schematic view showing the flow of wind in the cylindrical member 220 when the inclined member 270 is not provided by an arrow. Further, FIG. 10B is a schematic view showing the flow of wind when the cylindrical member 220 is closed by a flat plate 278 having a through hole at the center instead of the inclined member 270. FIG. 11 is a schematic view showing the flow of wind in the cylindrical member 220 when the inclined member 270 is provided by an arrow.

When nothing is provided near the exhaust port of the cylindrical member 220, as shown in FIG. 10 (A), the air is exhausted as it is while maintaining the spiral progress. On the other hand, when the flat plate 278 is provided, as shown in FIG. 10B, the air is blocked by the flat plate 278 and becomes a turbulent flow state near the exhaust port, and penetrates the flat plate 278 provided in the central portion. It will stay inside the cylindrical member 220 until it comes out of the hole. Therefore, the air is exposed to ultraviolet rays for this residence time, and the detoxification treatment of the pathogen can be extended as compared with that in FIG. 10 (A).

Further, as shown in FIG. 11, by providing the inclined member 270 having the inclined surface 272 inclined in one direction, the air traveling in a spiral shape is reflected by the inclined surface 272. The air reflected by the inclined surface 272 flows backward while maintaining the momentum before the reflection to some extent. That is, the region where the turbulence is formed becomes wider than that in FIG. 10 (B) and reaches the upper region. From this, the residence time of the air in the cylindrical member 220 is also longer than that of FIG. 10B, and the air is exposed to ultraviolet rays by this residence time, and the detoxification treatment of the pathogen is extended. can do.

Air is also reflected by the flat plate 278 shown in FIG. 10B, but in this case, since the angle of incidence on the flat plate 278 is shallow, the angle of reflection is also shallow and becomes closer to the horizontal. Therefore, the reflected air does not move upward to the extent shown in FIG. 11, but remains to the extent that a turbulent flow is formed in the vicinity of the exhaust port.

Referring to FIGS. 9 and 11, the inclined surface 272 of the present embodiment has the following features. That is, the inclined surface 272 is an inclined surface provided on the end side of the exhaust port of the cylindrical member 220, and the ventilation hole 271 is located on the axis of the cylindrical shaft C of the cylindrical member 220. Further, the inclined surface 272 is an inclined surface inclined in one direction (constant angle of angle θ) with respect to a surface (flat plate 278 or XY plane) having a cylindrical axis C as a perpendicular line. Here, "one direction" means that when the inclined surface is visually recognized from the horizontal lateral direction with respect to the inclined surface, the value of the inclination of the inclined surface is positive or negative and does not reverse (for example, the inclined surface 272 in FIG. 11). As shown, it is always rising to the left (always falling to the right)).

According to the embodiment of the present embodiment, the inside of the cylindrical member 220 can be spirally advanced to increase the distance, so that the irradiation time of ultraviolet rays can be lengthened. Further, by providing the inclined surface 272 on the downstream side after traveling in a spiral shape, a turbulent flow is formed on the downstream side. Therefore, the air can be further retained in the cylinder, and the ultraviolet rays can be irradiated for a long time by this amount.

<Usage example of air purification system>
Hereinafter, an example of using the above-mentioned air cleaning system 300 will be described.

FIG. 12 (A) is a perspective view showing a state when the air purification system 300 is attached to the face-to-face table 1200, and FIG. 12 (B) is a view when two people sit face-to-face on the table 1200. It is a figure which shows the state of.

A transparent or opaque plate-shaped panel 123 is sandwiched between the panel support portions 110 of the frame member 100, and this is placed at the center of the top plate 1201. As a result, a panel for partitioning the people facing each other across the table 1200 can be installed, and the air cleaning system 300 can also be installed at the same time. Further, in order to prevent the panel 123 from tipping over, a plurality of foot members 121 are provided on both side surfaces of the frame member 100.

Conversations between people facing each other across the table 1200, sneezing, breathing, and other exhalations are blocked by the panel 123, so that the frame member 100 that is performing inspiratory operation does not proceed toward the other party facing each other. It is taken inside (see FIG. 12B). The exhaled air (air) taken into the inside of the frame member 100 spirally travels inside the air purifying device 200, is detoxified by ultraviolet irradiation, and is exhausted.

As shown by the broken line arrow in FIG. 12 (A), by directing the exhaust to the lower side of the top plate 1201 of the table 1200, even if the pathogen that could not be detoxified is discharged, there is an opportunity for humans to directly touch it. The pathogen can be exhausted to the lower side of the table with less space, and the pathogen can be immediately landed on the floor. The exhaust of the air purifier 200 is oriented so as to be parallel to the extending direction of the frame member 100, and as a result, the pathogen is exhausted to the lower side of the table when it is installed on the table. Can be done.

In the example of FIG. 12A, a configuration in which four frame members 100 having a dimension of 30 cm in the long direction are connected is illustrated, but the number of connections is adjusted according to the size of the table. Can be done. Further, in FIG. 12A, the air purifying device 200 is provided at one end of the connected frame members 100, but the air purifying device 200 may be provided at both ends (air cleaning on both side surfaces of the top plate 1201). Each device 200 is in a hanging state).

With the configuration shown in FIG. 12, a panel for preventing splashes and an air purifier can be assembled and attached at the same time, such as in a restaurant or an office of a company. Further, by adopting the configuration shown in FIG. 12, the air purifier 200 can be mounted at a natural position that does not get in the way, not on the tabletop (top plate 1201) or the like.

Further, by adopting the configuration shown in FIG. 12, in the vicinity of the table where a person stays for a long time, that is, in the vicinity of a place where an infected person (source of pathogen) or a person who should be protected from infection stays for a long time. Since not only the splash prevention panel but also the air purifying device 200 can be attached, it can be useful for infection prevention.

FIG. 13 illustrates a configuration in which an air purification system 300 is attached to a partition 1300 that partitions a room. In the example of FIG. 13, a configuration example is shown in which intake air is taken in at a position above the partition 1300 and exhausted below the center of the partition 1300 in the height direction. By appropriately changing the length of the member of the cylindrical member 220 according to the height of the partition 1300, it is possible to exhaust the air to the vicinity of the floor, which is rarely touched by humans and easy to clean.

FIG. 14 is a diagram illustrating a state in which an air purifying system 300 is attached to a counter table 1400 provided along a wall in a room. In the example of FIG. 14, the frame member 100 is connected in an L shape, and the exhaust port is oriented so as to exhaust air toward the lower side of the counter table 1400 and toward the interior wall. By exhausting in such a direction, it is possible to discharge the pathogen that could not be detoxified to a position where there is little chance of direct contact with humans.

In the example of FIG. 14, since the air cleaning system 300 is provided on the counter table 1400 provided at the corner, the frame member 100 is arranged in an L shape, but the embodiment is not limited to this and does not get in the way. It may be arranged along the wall at the position.

FIG. 15 is a diagram illustrating a state in which the air purifying system 300 is attached to the ceiling corner of the room. For example, a hanging hook is attached to the indoor ceiling 1500, and the frame member 100 can be hung from the indoor ceiling 1500 by passing the hook through the hole 110A (see FIG. 2) of the frame member 100. Further, in the example of FIG. 15, the exhaust from the air purifier 200 is directed to be performed along the interior wall 1501.

FIG. 16 is a diagram illustrating a state in which the air purification system 300 is attached to the chaise longue. In the example of FIG. 16, the frame member 100 is provided on the upper part of the backrest 1601 of the chaise longue 1600, which is located close to the human face. Further, in the example of FIG. 16, the air purifying device 200 is provided so as to exhaust the air toward the lower side of the seat surface 1602, which is less likely to be touched by a person. Similar to the example provided on the table of FIG. 12, in the example of FIG. 16, since the air purifier 200 can be attached near the chair in which a person stays for a long time, it can be useful for infection prevention.

<Other variations>
Hereinafter, other variations of the units constituting the air purifier 200 will be described with reference to each drawing.

<Other configurations of inclined surface>
FIG. 17A is a perspective view showing an inclined member 270A having an inclined surface as a curved surface 272A, and FIG. 17B is a side view when the inclined member 270A is attached to the cylindrical member 220. As described above, instead of the flat inclined member 270 shown in FIG. 9, the inclined member 270A having a curved inclined surface may be provided in the air purifying device 200.

The terms "inclined" and "inclined surface" refer to an inclined and inclined surface, and as shown in FIG. 9, the inclination by a plane (as in the inclined surface 272, the degree of inclination is always equal). It may be an inclination due to a curved surface (inclination in which the degree of inclination changes depending on the position as in the curved surface 272A) as shown in FIG. Further, although the curved surface 272A shown in FIG. 17 is a curved surface that protrudes downward, it may be a curved surface that projects upward. In addition, it may be a bent surface whose angle changes in a plurality of steps.

<Other configurations of intake unit>
FIG. 18 is an exploded view of the air purifier 200 in which the intake portion composed of the upper cap 210 and the guide blade 250 shown in FIG. 4 is changed to the upper cap 280. Other than this, the configuration is the same as that shown in FIG.

FIG. 19A is a near-view view when the upper cap 280 is visually recognized from above, and FIG. 19B is a front view when the upper cap 280 is visually recognized from the opening 281. 19 (C) is a plan view (bottom view) when the upper cap 280 is visually recognized from the opening 282, and FIG. 19 (D) is a broken line in the plan view shown in FIG. 19 (C). It is the figure which added the air flow by the arrow.

The upper cap 280 is different from the configurations of the upper cap 210 and the guide blade 250 described so far, and the upper cap 280 is a single body of the upper cap 280 and serves as an intake portion that spirally advances the inside of the cylindrical member 220.

In order to realize this single unit configuration, the upper cap 280 has a cylindrical wall surface 283 and a side wall 284. The tubular wall surface 283 is formed so as to be flush with the inner side wall of the cylindrical member 220 by attaching the upper cap 280 to the cylindrical member 220. The side wall 284 is a side surface for defining a flow path from the opening 281 to the tubular wall surface 283, and is flush with a part of the tubular wall surface 283. The air flowing in from the opening 281 is smoothly guided to the cylindrical wall surface 283 via the side wall 284.

With this configuration, the air taken in from the opening 281 tends to first touch the side wall 284 and maintain contact with the side wall 284 due to the Coanda effect. Then, the air enters the cylindrical wall surface 283 as it is, and when it touches the cylindrical wall surface 283, it enters the inside of the cylindrical member 220 while keeping the cylindrical wall surface 283 due to the Coanda effect or centrifugal force. .. After entering the interior of the cylindrical member 220, the air spirals while maintaining swirling.

<Other configurations of purification equipment>
A configuration in which a surface irradiation lamp that irradiates a surface with ultraviolet rays is used instead of the ultraviolet lamp 260 will be described. Here, for example, as in the technique of Patent Document 2 described above, a plurality of thin tubes to be irradiated with ultraviolet rays are arranged side by side to form a surface configuration.

FIG. 20 is a diagram illustrating the surface irradiation lamp according to the present embodiment, and FIG. 21 is a diagram showing an example of an embodiment when the surface irradiation lamp is provided on the cylindrical member 220.

The surface irradiation lamp 260A has a configuration in which a plurality of ultraviolet irradiation tubes 2002 having a millimeter unit width (about 2 mm) are arranged side by side at minute intervals of about 2 to 3 mm on the surface of the mirror surface film 2001. The number, dimensions, spacing length, etc. of the ultraviolet irradiation tubes 2002 are not limited to this. Further, here, in order to reflect ultraviolet rays and amplify the amount of light, the mirror surface film 2001 is used as a base sheet, but the embodiment is not limited to this.

By arranging the thin tubes of the ultraviolet irradiation tube 2002 at intervals, it is possible to perform processing such as bending or bending the surface irradiation lamp 260A, and it can be flexibly deformed and applied to various member shapes. Here, the surface irradiation lamp 260A is rolled into a cylindrical shape and attached to the cylindrical member 220.

FIG. 21A illustrates a configuration in which three surface irradiation lamps 260A are prepared, each of them is formed into a cylindrical shape, and these are placed in a cylindrical member 220 to irradiate the inside. On the other hand, FIG. 21B illustrates a configuration in which a cylindrical member 220 is inserted inside three cylindrical surface irradiation lamps 260A. Also in FIG. 21B, by using the transparent cylindrical member 220, it is possible to irradiate the inside of the cylindrical member 220 with ultraviolet rays. The number of surface irradiation lamps 260A is not limited to this, and may be one or a plurality.

In the case of the configuration of FIG. 21 (A), as compared with the configuration of FIG. 21 (B), the surface irradiation lamp 260A can directly irradiate the air inside the cylinder, but the uneven surface of the surface irradiation lamp 260A. It is also assumed that the spiral progression of air is disturbed by the influence of (the uneven surface formed by the presence or absence of the ultraviolet irradiation tube 2002). On the other hand, in the case of the configuration of FIG. 21 (B), the spiral progress of the air is not disturbed as compared with the configuration of FIG. 21 (A), but the cylindrical member 220 is between the surface irradiation lamp 260A and the air inside the cylinder. Due to the presence of the wall, part of the ultraviolet rays is reflected and absorbed, and the transmittance is reduced. Considering these advantages / disadvantages, it is preferable to use a more suitable mounting.

<Integration of air purifier>
As shown in FIG. 22, by replacing the upper caps 210 and 280 described so far with the intake caps 290, the air purifier 200 can be provided in a single configuration without the frame member 100.

The intake cap 290 has a filter member 291 provided so as to orbit the side surface. The filter member 291 is a mesh-like member in which a large number of through holes for taking in the outside air of the intake cap 290 are formed, and is an air purifier for removing foreign substances such as dust and dirt floating in the air. Do not take it on board the 200.

The hole 212A of the intake cap 290 is a hole for fixing the guide blade 250 to the intake cap 290 using a biz. The hole 213A is a hole for fixing the intake cap 290 to the cylindrical member 220 by using a biz. The intake cap 290 and the guide blade 250 are fixed to the cylindrical member 220 by fixing the intake cap 290 and the guide blade 250 to these holes.

The mode in which the air purifier 200 is a single unit is not limited to this. For example, the air purifying device 200 may be provided alone by providing a filter member in the opening 211 of the upper cap 210 or the opening 281 of the upper cap 280 to prevent foreign matter from being taken in.

The shape of each member described in this embodiment is merely an example and is not limited. For example, although the cross-sectional shape of the frame member 100 is a rectangle in this embodiment, it may be a polygon or a circle (including not only a perfect circle but also an ellipse). In addition, the sizes and dimensions of each member described in the present embodiment are also merely examples and are not limited.

Although the air purifying device 200 and the air purifying system 300 of the present embodiment have been described as being mainly used indoors, they may be used outdoors. Further, although the air purifying device 200 and the air purifying system 300 have been described as exhausting air into the room, the air purifying device 200 and the air purifying system 300 may be configured to exhaust air to the outside by providing an exhaust duct or the like.

In this embodiment, an implementation example in which a pathogen is detoxified by irradiating with ultraviolet rays has been described, but the embodiment is not limited to this. A purification device that performs other detoxification treatments, such as detoxification using ozone, may be adopted.

The blower corresponds to the fan 240 of the present embodiment. The intake portion corresponds to a configuration including the upper cap 210 and the guide blade 250 of the present embodiment, or corresponds to the upper cap 280. The intake unit may be configured to include the intake cap 290 and the guide blade 250 of the present embodiment. The purification device corresponds to the ultraviolet lamp 260 or the surface irradiation lamp 260A of the present embodiment. The long member and the horizontal attachment correspond to one frame member 100 of the present embodiment, or correspond to a configuration in which a plurality of frame members 100 are connected.

(Second Embodiment)
In the first embodiment, the description mainly focuses on the air purifier, but in the second and subsequent embodiments, the attachment that sucks air and sends it to the air purifier will be focused on, and further variations will be exemplified.

FIG. 23 is a diagram showing an air purifying system 300A according to the second embodiment. 23 (A) is an upward perspective view of the air purification system 300A, and FIG. 23 (B) is an enlarged view of the region R shown in FIG. 23 (A). Further, FIG. 23C is an upward perspective view when the air purifying system 300A is visually recognized from a viewpoint different from that of FIG. 23A, and mainly shows the opposite surface of the panel 123.

The air purifying system 300A has an air purifying device 600 and an attachment 500.

The air purifying device 600 may be the air purifying device 200 described in the first embodiment described above, but the present invention is not limited to this, and an existing air purifying device may be adopted. That is, the air purifying device 600 may be a device that takes in air into the inside of the device by rotating a fan, detoxifies pathogens (a synonym for bacteria and viruses) contained in the taken in air, and exhausts the air.

The attachment 500 is a member connected to the air purifying device 600, and is a unit that takes in the surrounding outside air and guides the taken in outside air to the air purifying device 600. The attachment 500 can be roughly divided into two parts, one is a frame member 510 (= horizontal attachment) and the other is a bellows hose 530 (= telescopic attachment). The frame member 510 and the bellows hose 530 are connected by a connecting member 540, and each of these members is fixed to each other by using, for example, a biz.

In the following description, the frame member 510, the bellows hose 530, and the connecting member 540 are not limited, and the fixing method between the members is not particularly limited. It may be fixed by a biz, engaged by using a protrusion or the like, or may be fixed by using an adhesive depending on the embodiment.

The lower end of the bellows hose 530 is ventilatedly connected to the intake port of the air purifier 600. The bellows hose 530 is a member that can be expanded and contracted in the height direction so that the other end thereof can be brought close to or separated from the air purifier 600, and can be fixed and maintained at a target height. .. As the telescopic attachment, the bellows hose 530 is adopted in this embodiment, but the embodiment is not limited to this. For example, a configuration may be adopted in which a plurality of short tubular members are prepared and connected to each other, and the number of connecting stages is adjusted to achieve a target height. Alternatively, the same expansion / contraction mechanism as the expansion / contraction rod that prevents furniture or the like from tipping over in the event of an earthquake may be adopted.

By adjusting the bellows hose 530 to a suitable height, as shown in FIG. 23, the frame member 510 can be arranged so as to be in contact with the surface of the top plate 1201 of the table 1200.

The connecting member 540 connected to the upper end of the bellows hose 530 has, for example, the same configuration as the upper cap 210 (see FIG. 5) described in the first embodiment. The upper cap 210 in the first embodiment has a guide blade 250 (see FIG. 6) inside, but the connecting member 540 in the present embodiment may not have it.

The frame member 510 is a member whose end is connected to the connecting member 540, and is a member that takes in ambient air inside by the intake operation of a fan provided in the air purifying device 600. The taken-in air reaches the air purifier 600 via the connecting member 540 and the bellows hose 530.

Each of the frame members 510 is a horizontally extending member that guides the surrounding air attracted by the intake operation of the air purifier 600 toward the air purifier 600. Similar to the frame member 100 described in the first embodiment, each of the frame members 510 has a hollow inside so as to allow ventilation in the elongated direction of the members (FIGS. 2B and 2C). See also). Although FIG. 23 illustrates a configuration in which three frame members 510 are connected, only one frame member 510 may be connected, or the number of connected frames may be adjusted according to the size of the table 1200. Hereinafter, any one frame member 510 or a plurality of connected frame members 510 will be simply referred to as a frame member 510.

The exterior (outer shell) that separates the inside and the outside of the frame member 510 is provided with a plurality of holes 511 that allow ventilation between the inside and the outside, side by side along the long direction of the frame member 510. In the frame member 510 shown in FIG. 23, each of the holes 511 is an elongated hole having an elongated direction in the same direction as the elongated direction of the frame member 510, and is provided so as to open upward.

Further, each of the holes 511 is provided so as to form a row on both the left and right sides of the panel 123 (see FIGS. 23 (A) and 23 (C)). That is, the frame member 510 can take in the air around both the left and right sides of the panel 123. Therefore, as shown in FIG. 12 (B), when two people sit in a seat facing the panel 123 facing each other, the frame member 510 receives the exhaled air and the droplets from both of them blocked by the panel 123 through the holes 511, respectively. It can be taken inside through.

The attachment 500 shown in FIG. 23 has a fixture 520 for erecting the panel 123. The fixtures 520 are provided at both ends of the frame member 510 in the longitudinal direction in FIG. 23, but are merely examples, and may be any position and number as long as the panel 123 can be stably erected.

24 is a view showing the details of the fixture 520, FIG. 24 (A) is a perspective view of the fixture 520, and FIG. 24 (B) is a front view. Further, FIG. 24C is a view in which the fixture 520 shown in FIG. 24B is turned upside down.

The fixture 520 has a panel sandwiching portion 521 (second sandwiching portion) that sandwiches the panel 123 from both sides, and a frame sandwiching portion 522 (first sandwiching portion) that sandwiches the frame member 510 from both left and right sides facing in the elongated direction. )have. Further, the fixture 520 is provided with a horizontally overhanging foot portion 523, which can prevent the panel 123 from tipping over.

FIGS. 24A and 24B show a state in which the panel sandwiching portion 521 is on the upper side and the frame member 510 is on the lower side. That is, the mounting tool 520 is in the state shown in each drawing of FIG. 23, but when the mounting tool 520 is used upside down as shown in FIG. 24 (C), the frame is placed on the panel 123 as shown in FIG. 25. The member 510 can be provided.

FIG. 25 uses the same frame member 510 and the same fixture 520 as described in FIGS. 23 and 24, but illustrates a configuration in which the frame member 510 is provided on the panel 123. Further, a perspective view when viewed from above is shown in FIG. 25 (A), and a perspective view when viewed from below is shown in FIG. 25 (B).

In the case of the example of FIG. 25, a foot portion 124 for preventing a fall is provided at the lower portion of the panel 123. The frame member 510 located at the top of the panel 123 is supported by the upside-down fixture 520. The frame member 510 shown in FIG. 25 is provided upside down with respect to that of FIG. 23 so that the hole 511 is located downward (see FIG. 25 (B)). By providing the hole 511 downward in this way, it is possible to inhale the exhaled air and the droplets that are blocked and stayed by the panel 123 on the upper side.

By fixing each member of the frame member 510, the mounting tool 520, and the panel 123 to integrate them, and extending the bellows hose 530 upward, the panel 123 is passed through the frame member 510 and the mounting tool 520. Can be configured to hang. In this case, the fall prevention foot portion 124 becomes unnecessary. Further, in the case of hanging in this way, a transparent film sheet may be adopted instead of the panel.

FIG. 26 is a diagram showing another embodiment example using the same air purification system 300A, and is a diagram showing a case where it is applied to a panel provided with an opening window. The panel 123A shown in FIG. 26 (A) is provided with an opening window 125 at the lower portion, and persons seated facing each other can pass objects and the like through the opening window 125. When such an opening window 125 is provided, exhaled air and droplets pass through each other through the opening window 125 even if the panel 123A partitions the window 125.

Therefore, in the example of FIG. 26, the frame member 510 is provided immediately above the opening window 125 so that the hole 511 faces downward (see FIG. 26B for the hole 511 facing downward). The height of the frame member 510 is adjusted by the expansion and contraction of the bellows hose 610 as described above.

FIG. 27 is a diagram showing still another example of the embodiment, and FIG. 27 (A) is an upper perspective view of the air purification system 300A. 27 (B) is an upward perspective view when the air purifying system 300A is visually recognized from a viewpoint different from that of FIG. 27 (A), and mainly shows the opposite surface of the panel 126.

The panel 126 shown in FIG. 27 has a thin box shape, and a large number of holes 126A are provided on both side panel surfaces (surfaces facing the seated person) so as to occupy the entire surface.

The panel 126 takes in the outside air into the inside of the box shape through the hole 126A by the intake operation of the air purifying device 600. Here, if a part of the box-shaped (hexahedron) surface of the panel 126 is removed, the air taken in inside leaks out from there, which is not efficient. Therefore, in the present embodiment, all six surfaces of the panel 126 are closed, and ventilation to the outside is not performed except for the hole 126A.

Further, on the lower side of the inside of the box shape of the panel 126, a frame member 510 having holes 511 arranged upward is provided to take in the air inside the box shape of the panel 126. That is, the air containing exhaled breath and droplets emitted by a person is finally taken into the air purifying device 600 through the holes 126A and 511 by the intake operation of the air purifying device 600, and is purified. ..

In the second embodiment, an embodiment using a stretchable attachment as exemplified by the bellows hose 610 and a stretchable horizontal attachment by arbitrarily changing the number of connections has been described. This makes it possible to suck in air at any desired position. Further, the frame member 510 which is a horizontal attachment can be placed along the upper side portion or the lower side portion of the panel 123 which is a partition member, and can be configured according to the user's request and the situation of the installation place.

(Third Embodiment)
FIG. 28 is a diagram showing an embodiment using a frame member different from the above-mentioned second embodiment, and FIG. 28 (A) is a perspective view when the air cleaning system 300B of the third embodiment is visually recognized from diagonally above. 28 (B) is a perspective view when visually recognized from below.

The frame member 510A of the attachment 502 shown in FIG. 28 is the same as the second embodiment described above in that it is a member extended in the horizontal direction, but a plurality of frame members 510A are used in the connecting portion 540A. It has a cross-shaped radial structure that intersects. The frame member 510A and the upper end of the bellows hose 530 are connected by a connecting portion 540A.

The frame member 510A is provided with a plurality of holes 511 as in the second embodiment described above, and these holes 511 are provided so as to face downward (see FIG. 28B). Each of the frame members 510A can grip and suspend the transparent film sheet 127.

Each person seated on the four sides of the square table 1200 is partitioned by a transparent film sheet 127. Then, the exhaled breath and the droplets emitted by the seated person are blocked by the transparent film sheet 127, go upward on the intake side, and are taken into the inside of the frame member 510A. After that, the taken-in air is directed to the air purifier 600 via the bellows hose 610 and processed.

FIG. 29 exemplifies other variations in the third embodiment. FIG. 29 (A) is a view when the configuration of FIG. 28 is visually recognized from directly above. FIG. 29B is a diagram in which the frame member 510A radiated in a cross shape is arranged between two tables 1200A and 1200B arranged close to each other. By arranging in this way, it is possible to partition not only the facing seats but also the tables 1200A and 1200B.

Further, by applying the above, it is possible to partition each seated person even with a table layout as shown in FIG. 29 (C), for example.

In the third embodiment, each frame member is arranged so as to radiate from an arbitrary point (connecting portion 540A). By having such a configuration, it is possible to partition each person even if they sit side by side, diagonally, or surround them, in addition to sitting face-to-face, and the exhaled breath and droplets emitted from each person are transparent film. It can be blocked by the sheet 127 and taken into the inside of the frame member.

(Fourth Embodiment)
In the fourth embodiment, it is described to generate a jet flow (hereinafter referred to as “air curtain”) in which air is flowed in one direction up and down to take in surrounding air. This makes it possible to take in exhaled breath and droplets without providing a partition member such as a panel.

FIG. 30 is a diagram for explaining an embodiment of the fourth embodiment, and FIG. 30 (A) is a perspective view when the air purifying system 300C of the fourth embodiment is visually recognized from diagonally above. FIG. 30B is a front schematic view showing the air flow with arrows.

In the fourth embodiment, the air purifier 600 is provided on the table 1200 instead of the floor. Further, the attachment 503 has a bellows hose 530 that can be expanded and contracted in the vertical direction and a frame member 515A provided in the horizontal direction, and these are connected by a connecting member 540. This configuration is the same as the second and third embodiments described above, but in the fourth embodiment, the frame member 515B (second horizontal attachment) is connected to the exhaust port of the air purifier 600 in addition to this. Let me. The frame member 515A and the frame member 515B have the same shape, and each has an elongated hole 512A in the elongated direction. The frame member 515A and the frame member 515B are provided so that the elongated holes 512A provided in each of the frame member 515A and the frame member 515B face each other and are parallel to each other.

With such an attachment 503 configuration, the air circulation shown by the arrow in FIG. 30B can be realized. That is, by the intake operation of the air purifier 600, the surrounding air is taken in by the upper frame member 515A and proceeds to the air purifier 600 via the bellows hose 530. Then, the air treated by the air purifier 600 is exhausted from the lower frame member 515B. The exhausted air will be taken into the upper frame member 515A again. In this way, the air on the table 1200 will circulate.

When there is momentum in the intake air in the upper frame member 515A and the exhaust air from the lower frame member 515B, the surrounding air is entrained in this and taken into the upper frame member 515A. Therefore, the exhaled breath and the droplets emitted from the seated person are directed upward and taken into the frame member 515A. This makes it possible to form an "air curtain".

Although it is assumed that the air is blocked only by the air curtain here, a panel or a film sheet for partitioning each seated person may be provided as an auxiliary. Further, an air curtain may be formed in which the upper side is the exhaust side and the lower side is the intake side.

(Fifth Embodiment)
In the fifth embodiment, an embodiment for taking in and processing exhaled breath and droplets emitted by a patient lying in a bed as much as possible will be described. 31 (A) is a perspective view when the air purifying system 300D of the fifth embodiment is visually recognized from diagonally above, FIG. 31 (B) is a front view, and FIG. 31 (C) is a side view.

In the fifth embodiment, the upper body (headboard 701 side) of the patient 801 lying on the bed is surrounded and partitioned by the transparent film sheet 128. The film sheet fixative 702 is fixed to the headboard 701 of the bed 700 and is a frame for forming a spatial area surrounding the patient 801. In FIG. 31, the transparent film sheet 128 is not provided on the surface S1 on the side facing the patient 801 from the viewpoint of convenience, but the transparent film sheet 128 may be provided so as to surround the entire circumference.

The side surface S2 formed by the transparent film sheet 128 is provided with a hole for passing the tubular frame member 510C, and the hole is an intake hole 511A for sucking air inside the region surrounding the patient 801. Will be.

As shown in FIGS. 31A and 31B, the tubular frame member 510C is provided so as to be in the horizontal direction, and is connected to one end of the connecting member 540 so as to be ventilated. .. The other end of the connecting member 540 is ventilatedly connected to the end of the bellows hose 530. The attachment 505 of the fifth embodiment is configured to include the tubular frame member 510C, the connecting member 540, and the bellows hose 530 in this way, and is connected to the air purifying device 600. That is, it has the same configuration as each of the embodiments described so far.

The tubular frame member 510C takes in the air inside the region surrounding the patient 801 by the intake operation of the air purifying device 600, and the taken in air advances to the air purifying device 600 via the connecting member 540 and the bellows hose 530. ..
