Description

  The present invention relates to a smoking air cleaner installed in a smoking space for a vehicle such as a smoking space or a refresh space, and a smoking room provided with the same.

  Currently, there are three types of air purifiers that purify purple smoke from cigarettes. These are: 1. A type that cleans by directly sucking purple smoke. 2. A type where a certain space is enclosed by an air curtain or a partition plate so as not to emit purple smoke, and at the same time it is suctioned and cleaned. It is a combination of the above 1 and 2, and is a type that purifies purple smoke directly and cleans it, and prevents the purple smoke that could not be sucked out from the enclosure.

As the type {circle around (1)}, the followings of the present applicant are known.
JP-A-9-121947 According to this document, as shown in FIG. 7, the smoking counter a, which is an air cleaner, is disposed at an arbitrary location in the room of a building, and is provided with an exhaust port c on the side surface of the counter body b and an intake port on the upper surface. d, a shielding plate e is supported above the intake port d by a support column f, and an air cleaning device and a blower are provided in the counter body b between the intake port d and the exhaust port c. . When a person smokes in the vicinity of the smoking counter a, the purple smoke is guided by the shielding plate e together with the surrounding air, enters the counter body b from the intake port d, is cleaned by the air purifier, and is externally discharged from the exhaust port c. Exhausted.

The following are known as the type (2).
Japanese Utility Model Publication No. 7-35927 According to this document, as shown in FIG. 8, the smoking unit a1 that is an air purifier has an air outlet h around the ceiling part g in the room of the building, and an air inlet d in the center of the ceiling part g. There is an air curtain i from the air outlet h to create a smoking space A in combination with the floor j and the ceiling g, and the air in the smoking space A is sucked at the air inlet d of the ceiling g to obtain the smoking space A. The inside of the interior is temporarily brought to a negative pressure so that purple smoke and odors do not flow out to other spaces in the room, and are blown out again from the outlet h as clean air by an air purifying device in the ceiling g. It is something that is circulated as.

As the type {circle around (3)}, the followings of the present applicant are known.
JP 2001-174011 A According to this document, as shown in FIG. 9, an air flow control type smoke separator a2 that is an air purifier has a machine main body m in a shape in which a panel o is attached to a side portion of a box n, and the panel o Along with this, there is provided an air outlet h for forming an air curtain i for partitioning the interior of the building, and an air inlet d positioned in one smoking space A partitioned by the air curtain i in the box n, An exhaust port c located in the other non-smoking space B is provided in the panel o, an air purifying device is provided in the box n, and the exhaust amount of the cleaning air from the exhaust port c is at least from the non-smoking space B. Is set to be larger than the external entrainment air amount Q, and the inside of the smoking space A on the side of the intake port d divided into the room by the panel o and the air curtain i is in a negative pressure state. As a result, the purple smoke around the machine main body m in the smoking space A is immediately sucked from the air inlet d and purified air by an air cleaning device, and a part thereof is larger than the external entrained air amount Q from the air outlet c. The smoking space A is exhausted into the non-smoking space B so that the inside of the smoking space A is maintained in a negative pressure state, and the remaining purified air is blown out from the outlet h as an air curtain i, and purple smoke that has not been sucked into the inlet d Since the inside of the smoking space A is in a negative pressure state, it is finally sucked into the intake port d, cleaned air by an air cleaning device, and discharged from the exhaust port c to the non-smoking space B.

  If the smoking counter a in FIG. 7 is placed indoors, it becomes a smoking room having a purple smoke treatment function, and even if it is a smoker, it is convenient because it can satisfy the desire to avoid other people's purple smoke. . However, even if this smoking counter a is installed in the smoking room, if the smoker does not exhale purple smoke into the effective suction area around the intake port d of the smoking counter a, the purple smoke cannot be immediately sucked and drifts in the smoking room. As a result, the smoker is exposed to purple smoke and the above-mentioned desire is not satisfied, and the function of cleaning is impaired. This effective suction area depends on the suction capacity of the smoking counter a, and the only way to increase this is to increase the suction capacity. When this suction capacity is increased, the purified air is expelled from the lower exhaust port c to the floor surface, and it hits the wall in the smoking room and becomes turbulent, adversely affecting the effective suction area around the intake port d. Smokers will be exposed to purple smoke, and odor will be attached to their hair and clothing, even if the ventilation opening is in the smoking room, along with clean air from the door and other spaces. Purple smoke is also easily washed away to the outside.

  Moreover, if the smoking unit a1 of FIG. 8 is arrange | positioned indoors, it is convenient at the point which can become a smoking place which has a purple smoke processing function. However, since the smoking unit a1 is large-scale, it cannot be easily moved, and it is difficult to simply make the room a smoking place having a purple smoke treatment function. In addition, a pillar k that supports the ceiling part g is required, and even if it is a type that is suspended from the ceiling, the inside of the smoking space A can be temporarily brought into a negative pressure state, but the intake air in the center part Since the entire amount of air sucked from the mouth d becomes the air curtain i from the outlet h again, the inside of the smoking space A cannot be constantly in a negative pressure state, and purple smoke is outside the smoking space A. leak. Therefore, the smoking unit a1 cannot expect a smoke collecting effect and does not directly suck purple smoke, so even a smoker cannot satisfy the desire to avoid other people's purple smoke. Furthermore, in order to completely clear the standard of the health promotion method, it is necessary to surround the smoking space A with a wall, and the merit of the easy smoking place creation / exit of the smoking unit a1 is lost, which is troublesome.

  In addition, the airflow control type smoke separator a2 of FIG. 9 is a smoking area that easily has a purple smoke treatment function if it is placed in an indoor public space or the like, and even if it is a smoker, the desire to avoid the purple smoke of others. Even if the smoker leaves the effective suction area around the air intake d and exhales purple smoke, the smoke does not leak in the smoking space A created by the panel o and the air curtain i, and the smoke collecting effect is collected. It is convenient without greatly depending on. However, the airflow control type smoke separator a2 has a restriction that it cannot be advantageous unless it is installed near the wall of an indoor public space, and the intake port is similar to the smoking counter a in FIG. If you do not smoke in the effective suction area around d, purple smoke will not leak outside the smoking space A, but it will drift inside the smoking space A and affect smokers, and expecting to increase the suction capacity unnecessarily Does not lead to an increase in the effective suction area. Furthermore, in order to completely clear the standard of the health promotion method, it is necessary to surround the smoking space A with a wall, and the merit of the establishment of an easy smoking place where the air flow control type smoke separator a2 can freely enter and exit is lost, which makes it troublesome. .

  Therefore, the present invention has been made in view of the above circumstances, and even if it is installed in a smoking room with a small ventilation air volume, it can increase the effective suction amount of purple smoke around the suction port without increasing the suction capacity. It is an object of the present invention to provide a smoking air purifier and a smoking room in which the smoking air cleaner can be installed.

The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.
That is, the invention described in claim 1 provides at least one air inlet in the tangential direction on the wall surface of the cylinder standing upright at the upper part of the fuselage to form a tornado type suction port, and discharges it at the lower part of the fuselage. A discharge port portion having a flow velocity of less than 0.2 m / sec is provided, and an air cleaning device and a blower are provided in the body between the tornado type suction port portion and the discharge port portion that is downstream in terms of airflow. The air that sucks in air from the air inlet and forms a tornado in the cylinder, and further passes the air cleaning device in the airframe, and the purified air that is discharged from the discharge port has a flow velocity of less than 0.2 m / sec. The air cleaner for smoking is characterized by being prevented from generating turbulent flow in a constant space.

  The invention according to claim 2 is a smoking air cleaner characterized in that the tornado-type suction port is transparent and detachable from the airframe.

  The invention described in claim 3 is a smoking air cleaner characterized in that the tornado type suction port is lit up to improve the visibility of the tornado generated in the cylinder.

  According to a fourth aspect of the present invention, there is provided a smoking air cleaner characterized in that the tornado-type suction port portion is plural.

  According to a fifth aspect of the present invention, the discharge port portion extends on both sides of the machine body, and a baffle plate is provided in the extension portion so that the cleaning air from the air discharge surface of the extension portion is reduced to 0. A smoking air cleaner characterized by having a homogeneous breeze flow of less than 2 m / sec.

  The device according to claim 6 is provided with the air purifier for smoking installed in a fixed space, and provided with a vent and an inlet in the fixed space, and the inflow area of the inlet is the ventilation of the vent. It is a smoking room characterized by being set to an inflow air velocity of less than 0.2 m / sec with respect to the air volume.

  The invention described in claim 7 is a smoking room characterized in that the fixed space is installed in a vehicle.

As described in detail above, the present invention has the following effects.
According to the first aspect of the present invention, when the blower in the fuselage is driven, air flows in a tangential direction from the air inlet of the tornado-type suction port and is guided by the cylindrical wall surface to become a tornado, and then into the fuselage. The air is cleaned by an incoming air cleaning device and discharged from a discharge port at the lower part of the machine body as purified air having a slight wind flow of less than 0.2 m / sec. Therefore, since the air can be sucked in average from the air inlet by the tornado in the cylinder, the effective amount of purple smoke around the tornado type inlet can be increased without increasing the suction capacity, Since it is difficult for turbulent flow due to the clean air, it is possible to reduce the influence on smokers and to prevent purple smoke leakage from a certain space.

  According to the second aspect of the present invention, when a smoker exhales purple smoke around the tornado-type suction port, the purple smoke flows into the transparent cylinder from the air inlet at the transparent tornado-type suction port with the surrounding air. The tornado is visualized by the color of purple smoke. On the other hand, if the transparent cylinder becomes dirty with purple smoke over time and it becomes difficult to see the tornado in the cylinder, the tornado type suction port is removed, cleaned and reattached. Therefore, in addition to the above effect, trying to see the tornado generated in the cylinder, the smoker will exhale purple smoke around the air inlet of the tornado type suction port, and can efficiently inhale purple smoke, In addition, there is an effect that the tornado type suction port portion is kept transparent and the purple smoke suction efficiency can be maintained at a high level.

  According to the third aspect of the present invention, the tornado generated in the cylinder by light-up can be seen more clearly. Therefore, in addition to the above effects, there is an effect that purple smoke can be sucked even more efficiently.

  According to a fourth aspect of the present invention, purple smoke exhaled by a smoker flows into a transparent cylinder together with surrounding air from the inlets of a plurality of tornado-type suction ports, and becomes a visualization tornado containing purple smoke. Therefore, in addition to the above effect, there is an effect that purple smoke can be sucked in even more efficiently because there are a plurality of inlets of the tornado type suction port portion.

  The invention according to claim 5 is that the purified air purified by the air purifier inside the aircraft is divided into two by the discharge ports extending on both sides of the lower part of the aircraft, and is reduced to half. Then, it hits a baffle plate, attenuates its flow velocity, and is then pushed by the subsequent cleaning air to be discharged from the air discharge surface as a homogeneous breeze flow of less than 0.2 m / sec. Therefore, in addition to the above effects, it is possible to reliably suppress the occurrence of turbulent flow due to the clean air, further reduce the influence on the smoker, and prevent purple smoke leakage from a certain space.

  According to the sixth aspect of the present invention, when air is ventilated from a ventilation opening in a fixed space, outside air corresponding to the ventilation air volume enters at a flow velocity of less than 0.2 m / second from the inlet, but the entering outside air has a low flow velocity. Therefore, there is no directivity, and on the other hand, the cleaning air from the discharge port in the air purifier for smoking installed in a fixed space is also a direct air flow of less than 0.2 m / second, so there is no directivity and the outside air that has entered In addition, turbulent flow does not occur in the fixed space due to the cleaning air. Therefore, if a smoking air purifier is installed in the fixed space, the effective amount of purple smoke around the tornado-type suction port can be increased without increasing the suction capacity, and turbulence occurs in the fixed space. It is difficult to reduce the influence on smokers and to prevent purple smoke leakage from a certain space.

  The invention described in claim 7 has the same effect as described above even when the smoking air cleaner is installed in a fixed space of a vehicle to form a smoking room.

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

  FIG. 1 is a longitudinal sectional view of a part of a smoking air cleaner showing Embodiment 1 of the present invention, FIG. 2 is a plan view of the smoking air cleaner of FIG. 1, and FIG. 3 is III-III of FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 1, and FIG. 5 is a perspective view showing an outline of a tornado-type suction port in the air purifier for smoking in FIG. In the drawings, a smoking air cleaner 1 is installed in a vehicle, for example, a smoking room of a railway vehicle, and at least one air inlet 4 is provided on the wall surface of a cylinder 3 standing on the top of the body 2. Provided in the tangential direction as a tornado-type suction port 5, a discharge port 6 having a discharge flow velocity of less than 0.2 m / sec is provided at the lower part of the airframe 2, and downstream of the tornado-type suction port 5 in terms of airflow An air purifying device 7 and a blower 8 are provided in the airframe 2 between the exhaust port 6 and the air inlet 4 to suck air from the air inflow port 4 to form a tornado t and further clean the air in the airframe 2. The purified air formed by passing through the device 7 is discharged from the discharge port 6 as a slight wind flow with a discharge flow velocity of less than 0.2 m / second to prevent the generation of turbulent flow in a fixed space.

  The airframe 2 is a box having a substantially rectangular shape, although the back plate 10 is curved outward in accordance with the shape of the railway vehicle as the installation location. Two circular openings 12 are opened in the upper surface plate 11 of the airframe 2, and the tornado type suction port portion 5 is detachably attached on the upper surface plate 11. Communicate with each other through the circular opening 12. Then, side plate openings 13 are opened in both side plates 12 of the airframe 2, and the discharge port portion 6 is attached to both side plates 12, and the inside of the discharge port portion 6 and the airframe 2, that is, the following wind The box 16 communicates with the side plate opening 13.

  On the other hand, inside the airframe 2, a partition plate 14 is attached, the upper space thereof is a machine room 15 in which the air purifying device 7 and the blower 8 are provided, and the lower space is a wind box 16 for temporarily storing air. In the wind box 16, an ion generator 17 for negative ions and sterilization ions is attached.

  As described above, the tornado-type suction port 5 is provided with at least one air inlet 4 in the tangential direction on the wall surface of the cylindrical body 3, and its specific configuration is as follows. . That is, as shown in FIG. 5, the tornado-type suction port portion 5 of the first embodiment has two cylinders 3 and each cylinder 3 is provided with one air inlet 4. The front plate 20 and the back plate 21 that is curved in accordance with the shape of the railway vehicle, which is the installation location, like the back plate 10 of the fuselage 2 are connected by the side plates 22 on both sides and the central partition plate 23, and The flow guide partition plate 24, the ceiling plate 25, and the bottom plate 26 are formed. The tornado-type suction port 5 is divided into two cylindrical bodies 3 by a central partition plate 23, and is surrounded by the central partition plate 23, the side plate 12, the back plate 10, the flow guide partition plate 24, and the bottom plate 26. Two tornado generating chambers (hereinafter referred to as tornado generating chambers) are formed, and these two tornado generating chambers 3 have the same shape as the two circular openings 12 provided on the top plate 11 of the airframe 2. In addition to communicating with the hole 26 a formed in the bottom plate 26, the air inlet 4 formed between the upper surface plate 11 and the flow guide partition plate 24 is also communicated. The flow guide partition plate 24 is provided with a notch 24a so that when the air is sucked into the tornado generating chamber 3 which is curved and narrows as it goes to the upper part, both the upper part and the lower part are sucked uniformly. .

  Therefore, when the blower 8 in the machine room 15 is driven, air is sucked into the machine room 15 from the circular opening 12 on the upper surface of the machine body 2, and in conjunction with this, purple smoke is emitted from the air inlet 4 together with external air. The sucked air is guided to the upper surface plate 11 and the flow guide plate 24 of the air inlet 4 and uniformly enters the tornado generation chamber 3 at both the upper and lower portions as described above, along the wall surface. Since the air is sucked from the circular opening 12 of the airframe 2 located at the axial center portion of the swirling flow, the swirling flow becomes a tornado t that converges on the circular opening 12. This tornado t is a so-called in-pipe tornado, and due to the vortex convergence characteristic of the tornado t, both the portion near the ceiling plate 25 of the air inlet 4 and the portion near the top plate 11 of the airframe 2 The middle part of the air also sucks outside air almost uniformly. The air inlet 4 is provided with a net-like object 4a so that foreign matters such as butts and dusts do not enter directly.

  All the parts except the back plate 21 of the tornado type suction port 5 are transparent so that the tornado t generated in the tornado generating chamber 3 can be seen from the outside. It should be noted that the back plate 21 may be transparent, but of course, in order to further improve the visibility of the tornado t generated in the tornado generating chamber 3, it is lit up by a light 27 such as a line type LED. In this case, the tornado t is easier to see if the back plate 21 is not transparent. The tornado-type suction port 5 is detachable from the airframe 2, and as a result, even if the transparent tornado generating chamber 3 becomes dirty with purple smoke over time and the tornado t becomes difficult to see, the tornado-type suction port 5 5 can be easily removed, cleaned and reinstalled. Therefore, since the transparent state of the wound suction port can be maintained, the purple smoke suction efficiency can be constantly maintained at a high level.

  As described above, the discharge port 6 is provided at the lower part of the machine body 2 and has a discharge flow rate of less than 0.2 m / sec. The specific configuration is as follows. That is, the discharge port portion 6 of the first embodiment extends like a wing on both sides of the lower part of the machine body 2 and covers the side plate opening 13, and the baffle plate 31 is provided in the extension portion 30. The cleaning air from the air discharge surface 32 of the part 30 is made into a homogeneous fine wind flow of less than 0.2 m / sec. The air discharge surface 32 is formed by a net-like object 34 stretched over a large opening 33 in front of the extended portion 30.

  Therefore, when the blower 8 is driven, air is sucked from the tornado type suction port portion 5 and passes through the air cleaning device 7 to become purified air. This purified air enters the wind box 16 from the machine room 15, and further The air box 16 is divided into two hands by the two side plate openings 13 and enters the extended portion 30 of the discharge port portion 6, and the flow velocity is attenuated by the baffle plate 31, so that the net-like object 34 passes from the large opening 33 of the air discharge surface 32. , And the air is discharged with a slight wind flow of less than 0.2 m / sec.

  As described above, the air cleaning device 7 and the blower 8 are provided in the machine room 15 in the machine body 2 between the tornado type suction port portion 5 and the discharge port portion 6. The air cleaning device 7 has a pre-filter 40 that removes relatively large particles in the intake air, an electric dust collector 41 that removes fine particles that could not be removed by the pre-filter 40, and this electric dust collector 41 could not remove. It has a three-part configuration with a composite filter 42 that removes ultrafine particles, odor components, and harmful gas components. Further, instead of the electric dust collector 41, a mechanical filter capable of removing at least fine particles may be used, and an ultra-high performance mechanical filter having a function of removing ultra fine particles, odor components and harmful gas components may be used in combination. Good.

  The air blower 8 has the basic capacity and pressure required to form a breeze flow with a discharge flow velocity of less than 0.2 m / sec from the tornado t and the discharge port 6, and the air purifier 7. There is no particular limitation except that necessary conditions for the load and other losses are added.

  Moreover, since the smoker is smoking toward these when the information medium is installed in the airframe 2 of the smoking air cleaner 1, the tornado-type suction port part 5, and the discharge port part 6, these are inevitably. You will see the information media. The information medium is not particularly limited, such as a poster, a moving image, and a still image video medium. The content is not particularly limited, such as news, weather forecasts, and advertisements.

  And this air purifier 1 for smoking is installed in the fixed space, for example, the smoking room 51 of the rail vehicle 50 which is a vehicle, as shown in FIG. The smoking room 51 is provided with a ventilation port 52 and an inflow port 53. The inflow area of the inflow port 53 is set so that the inflow air speed is less than 0.2 m / sec with respect to the ventilation air volume at the ventilation port 52.

  Therefore, when air is ventilated from the ventilation port 52 of the smoking room 51, the outside air corresponding to the ventilation air volume enters from the inlet 53 at a flow velocity of less than 0.2 m / sec. On the other hand, the cleaning air from the discharge port 6 in the smoking air cleaner 1 installed in the smoking room 51 is also a directional flow because it is a slight wind flow of less than 0.2 m / second, and the outside air and clean Turbulent flow does not occur in the smoking room 51 due to the chemical air. For this reason, if the smoking air cleaner 1 of the present invention is installed in the smoking room 51, the effective suction amount of purple smoke around the tornado-type suction port can be increased without increasing the suction capacity. It is difficult for turbulent flow to occur in the interior, the influence on the smoker can be reduced, and purple smoke leakage from within the smoking room 51 can also be prevented.

Next, the use situation of the air cleaner 1 for smoking configured as described above will be described.
First, the smoking air cleaner 1 is installed in the smoking room 51 of the railway vehicle 50. In that case, the inflow area of the inflow port 53 of the smoking room 51 is set so that the inflow air velocity is less than 0.2 m / sec depending on the ventilation air volume from the ventilation port 52. When the smoker smokes the cigarette in the smoking room 51 while the blower 8 in the airframe 2 is driven, purple smoke is generated, and the purple smoke flows together with the surrounding air into the airflow in the tornado suction port 5. Uniform suction due to the characteristics of the tornado t already generated in the tornado generating chamber 3 from the inlet 4 and flows in the tangential direction, is guided by the wall surface of the tornado generating chamber 3 to become a new tornado t, and then the circular opening 12 The air enters the machine room 15 of the machine body 2 and is cleaned by the air cleaning device 7. The cleaned air enters the wind box 16 and is mixed with negative ions and sterilization ions from the ion generator 17, and receives the respective effects. Thereafter, the air enters the discharge port 6 through the side plate opening 13, the flow rate of the cleaning air is attenuated by the baffle plate 31, and the smoking room is used as cleaning air with a slight wind flow of less than 0.2 m / second from the air discharge surface 32. 51 is discharged into

  In addition, since the inflow area of the inlet 53 of the smoking room 51 is set so as to have an inflow air velocity of less than 0.2 m / sec with respect to the ventilation air volume of the ventilation port 52, the outside air entering from the inflow port 53 is also reduced. Since the wind flow is less than 0.2 m / second, there is no directivity and there is no turbulence with the clean air.

  On the other hand, the tornado t generated in the tornado generating chamber 3 is transparent to the tornado-type suction port 5 other than the back plate 21, so that the smoker can see the tornado t illuminated by the light 27. In addition, since it is difficult to see if the tornado t is not visible without the purple smoke, the smoker actively spits out the purple smoke toward the air inlet 4 of the tornado-type suction port 5. Therefore, even if the suction capacity of the smoking air cleaner 1 itself is not increased, the effective suction amount of purple smoke can be increased, and the turbulent flow due to the supernatant purification air and the external inflow air is less likely to occur. Further, leakage of purple smoke from the inside of the smoking room 51 can be prevented. In addition, if purple smoke adheres to the tornado-type suction port 5 and it becomes difficult to see the tornado t, the tornado-type suction port 5 is detachable and can be easily washed. If there is one spare for the tornado-type suction port 5, the tornado-type suction port 5 that is cleaned and replaced with the tornado-type suction port 5 that is dirty and less transparent will always be visible. You can always enjoy the effect.

  As mentioned above, although Example 1 of this invention was demonstrated, a specific structure is not limited to this, The change and addition in the range which does not deviate from the summary of this invention, the thing concerning other combinations in each claim, It should be understood that this is possible as appropriate.

  The smoking air cleaner of the present invention can be installed and used in smoking rooms, smoking corners, etc., but especially in smokers with low ventilation airflow such as railway vehicles, the effective suction amount of purple smoke without increasing the suction capacity When it is desired to reduce the influence on smokers and to prevent leakage of purple smoke from the smoking room, the applicability becomes extremely high.
