Description

Filter device

The present invention relates to a filter device.

2. Description of the Related Art Conventionally, a filter device is known that collects dust from air using a mesh-like filter (filter medium) for separating dust, dust, and other pathogens (hereinafter referred to as dust) contained in the air ( For example, Patent Document 1).

JP 2013-99749 A

By the way, in the filter device which collects dust with the conventional mesh filter, there is a problem that although the dust can be collected, the quality of the air itself cannot be improved.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a filter device capable of improving the quality of air.

In order to achieve the above object, a filter device of the present invention includes a plurality of tubular members around which a coil is wound around an outer peripheral portion and air passes through the inside, and a power source for causing a current to flow through the coil. ,
The plurality of tubular members are arranged with their directions aligned.

In the present invention, a plurality of tubular members are aligned in the same direction. A coil is wound around the tubular member, and a current is supplied to the coil from a power source. And air passes the inside of a tubular member.
A magnetic field is generated inside the tubular member by causing a current to flow through the coil, and each molecule in the air passing through the inside of the tubular member is affected by this magnetic field. And the molecule | numerator exposed to the magnetic field becomes easy to ionize. Moreover, negative ions are generated when charged particles or the like in the air receive a force from a magnetic field or an electric field and become active and collide with molecules in the air or the inner wall of the tubular member. Therefore, negative ions increase and the air is purified, so that the air quality can be improved.
In addition, since harmful substances are decomposed and the air is purified by the collision of charged particles whose movement has become active, the quality of air can be improved.

In the above-described configuration of the present invention, it is preferable that the coil includes a portion wound clockwise around the tubular member and a portion wound counterclockwise.

According to such a configuration, charged particles or the like passing through the inside of the tubular member are subjected to a force from a magnetic field whose direction changes alternately. Therefore, compared with the case where only a coil is wound in one direction, the movement of charged particles and the like becomes more random and active, molecules are likely to react, and negative ions are also likely to be generated. Therefore, the air passing through the inside of the tubular member is cleaner and becomes higher quality air.

Further, in the configuration of the present invention, it comprises at least one laser device that emits a sterilizing laser beam,
It is preferable that the laser device is arranged so that the laser beam passes on an extension line of one end of at least one of the plurality of tubular members.

According to such a configuration, the air passing through the tubular member is irradiated with the sterilizing laser light emitted from the laser device before flowing into the tubular member or after flowing out of the tubular member.
Therefore, while ionizing air, the microbe contained in air can be killed and the quality of air can be improved more.

Further, in the configuration of the present invention, it comprises at least one laser device that emits a sterilizing laser beam,
In the laser device, the laser light emitted from one of the laser devices passes on an extension line of one end of at least two of the plurality of tubular members. It is preferable to arrange | position.

According to such a configuration, the laser light emitted from one laser device passes through the extended line shape at one end of two or more tubular members.
Therefore, in order to kill the bacteria contained in the air passing through the tubular member, it is not necessary to provide the same number of laser devices as the tubular member, and the number of necessary laser devices can be reduced.

According to the filter device of the present invention, the air quality can be improved.

It is designed to be as wide as it is open. At this time, the thin film portion 32 is folded in a bellows shape (see FIG. 9).
In addition, it is good also as changing the connection method of the introducing | transducing part 30 and the structure 10 so that the front surface of the structure 10 may be covered completely in the state which the introducing | transducing part 30 closed most.

Further, the two cylinders 36 connected to the upper plate-like portion 31a are contracted or the two cylinders 36 connected to the left or right plate- like portions 31b and 31c are extended, so that the introduction portion 30 is expanded. Opens. In addition, the thin film portion 32 gradually spreads from the folded bellows shape with the apex angle (corner on the structure 10 side) 32a of the isosceles triangle as a fulcrum from the state where the introduction portion 30 is opened (see FIG. 9). In the state where the introduction part 30 is opened to the maximum, the state is stretched in a flat shape. And the introduction part 30 becomes a trumpet shape that spreads forward from the structure 10 in this fully opened state.
It should be noted that to what extent the plate- like portions 31a, 31b, 31c can be opened with respect to the structure 10 (the angle formed by the structure 10 and the plate- like portions 31a, 31b, 31c when opened to the maximum). The number of times may be set as appropriate as necessary.

It may be in the shape of a truncated quadrangular pyramid with a reduced cross-sectional area. Moreover, other truncated pyramid cylinder shape or truncated cone cylinder shape may be sufficient.
Moreover, the introduction part 30 may not be a trumpet shape connected in the circumferential direction. That is, the plate-like portions 31 may not be connected by the thin film portion 32, and a gap may be provided between the plate-like portions 31. Even with such a shape, air can be guided to the air intake portion 21 by the introduction portion 30.
Moreover, the introducing | transducing part 30 may be provided anywhere if the air can be guide | induced toward the air intake part 21 from the exterior of the dust collector 3. As shown in FIG. For example, when the air intake portion 21 is provided on the rear side wall member 24 of the structure 10, the introduction portion 30 may be provided on the rear surface of the structure 10. Moreover, the introducing | transducing part 30 may not be directly connected to the structure 10, but may be connected via another member.

In the rotating device 310, the rotating shaft 312 rotates by connecting the clutch 314 and operating the prime mover 313. As the rotary shaft 312 rotates, the impeller 317 provided on the rotary shaft 312 rotates so that air can flow from the air intake portion 21 toward the air discharge portion 25. That is, the rotating device 310 functions as a dust collector air blower that allows air to flow from the air intake unit 21 toward the air discharge unit 25. Further, along with the rotation of the rotating shaft 312, the permanent magnet 315 provided on the rotating shaft 312 rotates, and power generation is performed by the cooperation of the permanent magnet 315 and the coil 318.

Further, the air compressed by the rotating device 310 is ejected from the ejection device 80. For this reason, the dust collection by the dust collection vehicle 1 can be performed only by moving the prime mover 313 of the rotating device 310.
Therefore, the dust collector 3 can be used even in a place where it is difficult to secure a power source. Moreover, there is no need to load an extra battery.
Moreover, you may use the air compressed with the rotation apparatus 310, and the produced | generated electricity for another use. That is, the dust collection vehicle 1 can also be used to supply compressed air and electricity to other devices not related to dust collection.

In addition, when stopping at a place where a power source can be secured (for example, a place where an outlet is present) and collecting dust by the dust collecting vehicle 1, the rotating device 310 can be moved using a power source such as an outlet. That is, for example, when using a power source of an outlet, the AC power obtained from the outlet is converted into direct current through an inverter, and the current from the inverter is passed through the coil 318, thereby generating a magnetic field in the coil 318 and affecting the permanent magnet 315. As a result, the rotary shaft 312 rotates. Therefore, by disengaging the clutch 314 and moving the rotating device 310 with a power source such as an outlet, the air can be compressed and the air blown by the rotation of the impeller 317 without using the prime mover 313.

Note that the air compression may not be performed by the rotation of the impeller 316. For example, a reciprocating compressor that reciprocates a piston using the rotation of the rotating shaft 312 or a single screw compressor or a twin screw compressor in which a screw is provided on the rotating shaft 312 may be used.

In the dust collection vehicle 1 of the present embodiment, the dust collection vehicle 1 includes the vehicle body 2 that travels by the power of the prime mover, and therefore can travel. Therefore, the dust collecting vehicle 1 can be easily moved to a place where it is desired to clean the air.

Further, the air flows from the air intake unit 21 toward the air discharge unit 25 by the rotation of the impeller 317 of the rotation device 310. Then, air is taken into the air intake unit 21 from the outside of the dust collector 3.
Further, the dust collector 3 is provided with an introduction portion 30 so as to surround the front side wall member 20 of the structure 10 in which the air intake portion 21 is provided. Since the introduction part 30 has a wide opening on the opposite side to the air intake part 21, the air coming toward the introduction part 30 is guided to the air intake part 21. Therefore, a wider range of air can be taken into the dust collecting device 3 than in the case where the introduction unit 30 is not provided.
In particular, when the dust collection vehicle 1 performs dust collection while the dust collection vehicle 1 is traveling, the effect of the introduction unit 30 is great. That is, during the traveling of the dust collection vehicle 1, the air flow from the air intake unit 21 to the air discharge unit 25 is also generated by the traveling of the dust collection vehicle 1. Therefore, more air and dust can be taken into the dust collecting device 3.

The air taken into the dust collector 3 from the air intake 21 first passes through the first filter body 51 of the first filter device 50, and a part of the dust contained in the air is captured by the first filter body 51. Be collected.
The air that has passed through the first filter body 51 then passes through the tubular member 102 of the second filter device 100. Since the coil 101 is wound around the tubular member 102 and an electric current is passed through the coil 101, the air that has passed through the tubular member 102 is ionized and cleaned.
The air that has passed through the tubular member 102 is then applied to the laser light L of the third filter device 150. Since the laser light L has a sterilizing power, bacteria contained in the air passing through the laser light L are killed. Moreover, since high sterilization power is obtained by using the laser light L compared with the case where an ultraviolet light is used, it can sterilize also with respect to the air which passes the laser light L.
Next, the air applied to the laser light L passes through the activated carbon filter 201 of the fourth filter device 200. Then, carbon monoxide, carbon dioxide, exhaust gas and the like contained in the air are adsorbed by the activated carbon filter 201. Further, the activated carbon filter 201 also performs deodorization such as ammonia odor.
The air that has passed through the activated carbon filter 201 then passes through the HEPA filter 251 of the fifth filter device 250. The bacteria killed by the laser beam L and other dust remaining in the air are collected by the HEPA filter 251.
The air that has passed through the HEPA filter 251 then passes through the cooling bed 301. Since the cooling bed 301 is moistened with water, the air passing through the cooling bed 301 is cooled.
As described above, the cleaned and cooled air is discharged from the air discharge unit 25.

In addition, arrangement | positioning with each filter apparatus and the rotation apparatus 310 is not restricted to the order of this embodiment. It is only necessary that the rotation device 310 allows air to flow from the air intake portion 21 toward the air discharge portion 25 so that the air passes through each filter device.
Moreover, each filter apparatus and the cooling bed 301 may be provided only with what is required according to the dust to collect or the necessity of cooling of air. At this time, the structure 10 provided with each filter device and the like is constructed of a framework by the structural material joint 11 and the structural material 17, so that it can be easily adapted to the number and size of the devices and the like to be provided inside. In addition, the structure 10 can be enlarged or reduced.
The first filter body 51 and the HEPA filter 251 may use different types of air filters or the like depending on the type of dust to be collected.

Such a dust collecting vehicle 1 is, for example, a place where events such as festivals are held, a place where people such as schools gather, a place where the traffic of vehicles is heavy, a place where air is easily contaminated, a place where it is dirty, etc. Used to stop. The dust collection vehicle 1 includes a vehicle main body 2 that is a truck on which a 20-foot container can be loaded and can be driven by the power of the prime mover. Therefore, the dust collection vehicle 1 is placed in such a place only when people gather. It is possible to move 1 to remove dust in the air or to cool the air.
Since the dust collector 3 can be handled in the same manner as a normal container and can be easily removed, the dust collector 3 can be removed and installed to clean the air.

The dust collecting vehicle 1 can also be used while traveling. For example, the air in such an area can be purified by running in an area where air pollution is severe.
Moreover, since the air blower 4 is provided in the lower part of the driver's seat 2a in the lower part of the driver's seat 2a of the vehicle body 2 with the air outlet 4a directed downward and rearward, the air blower 4 is operated. Wind is blown from the blower 4 toward the ground, and dust on the ground is blown toward the plate-like portion 31d and the air intake portion 21. Therefore, by moving the dust collecting vehicle 1 while moving the blower 4, the blown-up dust can be sucked into the dust collecting device 3 and collected. Therefore, dust falling on the ground can be collected like a road surface cleaning car. In a conventional road sweeper that sucks in the dust on the ground like a vacuum cleaner, the area where the suction force is applied is narrow and the suction force is weak. . Further, in the case of a road surface cleaning vehicle that collects dust on the ground using a brush, it is necessary to periodically replace the brush, which requires a running cost. On the other hand, in the dust collection vehicle 1 according to the present embodiment, the air blower 4 can blow dust and the like on the ground toward the plate-like portion 31d and the air intake portion 21, so that dust can be collected. Dust etc. can be collected even if the vehicle 1 for dust collection is run quickly, and costs such as brush replacement do not occur.
Further, by increasing the strength of the wind sent from the blower 4, relatively large dust can be collected. Therefore, for example, the dust collection vehicle 1 can be used to collect pieces of a tire, pebbles and the like of an airplane tire that have fallen on the runway of the airplane, or to maintain a playground. Further, the first filter body 51 of the first filter device 50 and the like may be changed so as to be a filter suitable for collecting dust or the like according to the size of dust or the like to be collected.

In the first filter device 50 according to the present embodiment, the turbine 52 is rotated by air flowing from the front to the rear of the first filter device 50. The rotation of the turbine 52 is transmitted to the roller 53c via the belt (power transmission unit) 54, and the roller 53c rotates. The first filter body 51 stretched between the three rollers 53 rotates around the roller 53c.

Therefore, the surface of the first filter main body 51 facing the air flowing side (air intake portion 21 side) is sequentially changed. That is, in the first filter main body 51, the surface that mainly functions as a filter is the surface facing the fluid flowing side, but by circulating the first filter main body 51, the fluid flowing side The surface functioning as a filter can be turned around. For this reason, the effective area of the filter can be widened, and the filter is not easily clogged without replacing the filter. Therefore, the filter performance of the first filter body 51 can be maintained for a long time. Moreover, since the force of collecting the dust on the filter is difficult to drop, the air can be efficiently cleaned.

Moreover, since the 1st filter main body 51 can be circulated by natural forces, such as a wind and a water flow, it is not necessary to provide the motor etc. for rotating the 1st filter main body 51. FIG.
Moreover, the 1st filter main body 51 can also be circulated by this flowing air by using together with the apparatus which flows air like the rotation apparatus 310 of the vehicle 1 for dust collection which concerns on this Embodiment. Then, for example, the rotational speed of the first filter body 51 can be adjusted by adjusting the rotational speed of the rotary shaft 312 of the rotating device 310.

Moreover, the ejection apparatus 80 is arrange | positioned inside the 1st filter main body 51, and the jet nozzle 82a of the some ejection part 82 is orient | assigned to the 1st filter main body 51 side below. The air compressed by the rotating device 310 is ejected from the ejection port 82a. Further, a dust collecting unit 58 and a dust storage unit are provided below the first filter device 50.
Therefore, dust adhering to the first filter body 51 is pushed out by the air ejected from the ejection port 82 a, and the dust is stored in the dust storage unit through the dust collection unit 58. Further, the plurality of ejection portions 82 are provided in the axial direction of the pipe 81 extending in the left-right direction, and the first filter body 51 circulates around the pipe 81 due to the rotation of the turbine 52.
Dust from the entire filter can be removed and stored in the dust storage unit.
Therefore, the first filter body 51 is not clogged, and the filter performance can be maintained for a long time. Further, since dust is pushed out by air, the filter is less likely to be damaged and the filter performance can be maintained for a long period of time compared to a method in which dust is removed by rubbing the filter with a brush or the like.

In the second filter device 100 according to the present embodiment, the rear plate 104 is provided with a plurality of holes 105 aligned in the vertical direction and the left-right direction, and the front plate 103 also has holes 105 in the rear plate 104. A hole is provided at a position opposite to. In addition, one end of the tubular member 102 is fitted into the hole 105 of the rear plate 104, and the other end is fitted into the hole of the front plate 103 at a position facing the hole 105. . Therefore, the tubular members 102 are aligned and aligned in the up-down direction and the left-right direction with the shaft directed in the front-rear direction.
In addition, a coil 101 is wound around the outer peripheral portion of each tubular member 102 between the front plate 103 and the rear plate 104, and a current flows from the rotating device 310 to the coil 101. The air that has passed through the first filter device 50 passes through the inside of the tubular member 102 of the second filter device 100.
A magnetic field is generated inside the tubular member 102 by causing a current to flow through the coil 101, and each molecule in the air passing through the tubular member 102 is affected by the magnetic field. And the molecule | numerator exposed to the magnetic field becomes easy to ionize. Moreover, negative ions are generated when charged particles or the like in the air receive a force from a magnetic field or an electric field and become active and collide with molecules in the air or the inner wall of the tubular member. Therefore, negative ions increase and the air is cleaned.
Moreover, harmful substances are decomposed and the air is cleaned by collision of charged particles whose movement is active.
Moreover, since the tubular member 102 is made of copper and is heated when a current flows through the coil 101, the bacteria in contact with the tubular member 102 can be killed. Therefore, the air passing through the inside of the tubular member 102 is cleaned. The tubular member 102 is not limited to copper but can be heated and kill bacteria even if it is made of other metals.

Further, the coil 101 includes a counterclockwise portion 101a in which the coil 101 is wound counterclockwise when viewed from the front side in the axial direction, and a clockwise portion 101b wound in the clockwise direction. Further, the counterclockwise portion 101 a and the clockwise portion 101 b are alternately and repeatedly arranged along the axial direction of the tubular member 102. For this reason, charged particles or the like passing through the inside of the tubular member 102 receive a force from a magnetic field whose direction changes alternately. Therefore, as compared with the case where only the coil 101 is wound in one direction, the movement of charged particles or the like becomes more random and active, molecules are likely to react, and negative ions are likely to be generated. Therefore, the air passing through the inside of the tubular member 102 is further purified.

Further, in the third filter device 150 according to the present embodiment, the laser device 151 is fitted into the hole 154 and the hole 156 arranged in the left-right direction so that the laser light L is emitted directly downward. It is provided in the state. The plurality of holes 154 and holes 156 arranged on the front side are arranged at the same pitch P in the left-right direction, and the plurality of holes 154 and holes 156 arranged on the rear side are arranged at the same pitch P in the left-right direction. Although arranged, the hole 154 or the hole 156 arranged on the rear side is located at the center position between the holes 154 and 154 or the holes 156 and 156 which are arranged on the front side and adjacent to the left and right. That is, the hole 154 and the hole 156 are provided side by side in the left-right direction, and the adjacent hole 154 and the adjacent hole 156 are arranged at positions shifted in the front-rear direction.
Therefore, it is possible to prevent the adjacent laser devices 151 from colliding with each other in the left-right direction, and to arrange the laser devices 151 with a small interval in the left-right direction. In particular, when the laser device 151 has a portion that protrudes in the left-right direction, the effect of shifting the adjacent holes 154 and the adjacent holes 156 in the front-rear direction is great. Further, the hole 154 (hole 156) disposed on the front side and the hole 154 (hole 156) disposed on the rear side adjacent to the left and right are partially overlapped in the left-right direction. It can also be arranged.

Further, the air passing through the second filter device 100 passes through the tubular member 102. Therefore, when the air that has passed through the second filter device 100 is sterilized by the third filter device, the laser device 151 can be arranged so that the laser light L passes through the rear extension of each tubular member 102. desirable.
In the third filter device 150 according to the present embodiment, the laser devices 151 are arranged with a small distance in the left-right direction, so that the rear extension lines of the tubular members 102 arranged in the left-right direction at predetermined intervals are arranged. A laser device 151 is arranged so that the laser light L passes. Further, the laser light L emitted from one of the laser devices 151 passes on the rear extension line of the tubular member 102 aligned at a predetermined interval in the vertical direction.
In addition, one laser device 151 is provided for each vertical row of the tubular members 102 arranged, and the laser light L emitted from one laser device 151 is aligned in a vertical direction. All of the tubular members 102 pass over the axial rearward extension line. Therefore, the sterilizing laser light emitted from the laser device 151 is applied to the air flowing out from the tubular member 102.
Therefore, the bacteria contained in the air that has passed through the second filter device 100 can be killed by being irradiated with laser light having a large amount of heat and high sterilization power, and the air can be purified.
Further, the number of necessary laser devices 151 can be obtained by allowing the laser light L emitted from one laser device 151 to pass along the axial rearward extension lines of all the tubular members 102 aligned in the vertical direction. Has been reduced.

Further, in rotating device 310 according to the present embodiment, rotating shaft 312 is rotated by the rotation of prime mover 313. Then, by rotating the rotating shaft 312, power generation by the cooperation of the permanent magnet 315 and the coil 318, air blowing by the rotation of the impeller 317, and air compression by the rotation of the impeller 316 are performed.
Therefore, ventilation, power generation, and gas compression can be performed by one power source.
Further, the permanent magnet 315, the impeller 316 and the impeller 317 are provided on one rotating shaft 312. That is, the permanent magnet 315, the impeller 316, and the impeller 317 are coaxially arranged.
Therefore, the size of the rotating device 310 in the radial direction of the rotating shaft 312 can be reduced, and the rotating device 310 can be reduced in size, so that the rotating device 310 can be installed in a space-saving manner.

When the adjustment knob 331 is turned in the direction in which the wire 329 is loosened, the connection member 328 moves via the adjustment mechanism inside the second support member 327, and the blade 325 is parallel to the rotation direction of the impeller 317 ( It rotates so as to face the direction perpendicular to the rotation shaft 312. When the adjustment knob 331 is turned in the direction in which the wire 329 is pulled, the connection member 328 moves via the adjustment mechanism inside the second support member 327, and the blade 325 is in a direction perpendicular to the rotation direction of the impeller 317 ( It rotates so as to face in a direction parallel to the rotation axis 312.
Therefore, the angle of the impeller blades can be changed, and the pressure applied to the air by the impeller and the amount of air sent by the rotation of the impeller can be adjusted as necessary.

Moreover, in the dust collection vehicle 1 according to the present embodiment, the introduction part 30 is in the most closed state, and the area of the opening opposite to the structure 10 is the same as that before the air intake part 21 is provided. The plate-shaped portion 31d on the lower side of the side wall member 20 has an open area that is larger than that of the side wall member 20, and in the open state, from the most closed state to the opposite side of the structure body 10. The opening is designed to open. Therefore, since the area of the opening on the opposite side is larger than the area of the opening on the air intake part 21 side in the open state, the introduction part 30 collects wind coming toward the introduction part 30 to collect the air intake part. 21. Therefore, since a wide range of air can be guided to the inside of the dust collector 3 and cleaned by the introduction unit 30, the air can be efficiently cleaned.
In addition, the plate-like portion 31 which is a part of the introduction portion 30 is connected to the structure 10 via an extendable cylinder 36, and the plate-like portion 31 is moved vertically or horizontally by the expansion and contraction of the cylinder 36. Swing. And the introduction part 30 opens and closes when the plate-shaped part 31 swings. Therefore, the introduction part 30 is in an openable / closable state, and the introduction part 30 can be easily traveled even in a narrow place by closing the introduction part 30.

Moreover, the introduction part 30 is provided in the front side of the structure 10 in which the air intake part 21 is provided, and in the closed state, the upper plate-like part 31a protrudes from the structure 10 to the front side. The left and right plate- like portions 31 b and 31 c are substantially parallel to the left and right surfaces of the structure 10 in a state where the left and right plate- like portions 31 b and 31 c protrude from the structure 10 to the front side. Then, from this state, the front of the upper plate-like portion 31a opens upward, and the left and right plate- like portions 31b and 31c open in the left-right direction, whereby the introduction portion 30 is in the open state. That is, the opening part on the side opposite to the air intake part 21 is directed forward in the traveling direction of the dust collecting vehicle 1 in the open state. Therefore, when the dust collection vehicle 1 travels, air can flow from the introduction unit 30 to the air intake unit 21 and the air discharge unit 25. Therefore, by running the dust collection vehicle 1, dust in the air Can be collected, and a wide range of air in which the vehicle 1 for dust collection is run can be purified.
Therefore, the air can be efficiently cleaned.

In the dust collection vehicle 1 according to the present embodiment, the blower 4 is provided at the lower part of the driver's seat 2a with the blower port 4a facing downward and rearward. The dust contained in the air includes dust that repeatedly falls on the ground or resprays. However, since the dust that has fallen on the ground can be lifted and collected by the blower 4, it is efficient. It can collect dust and clean the air.

In addition, among the plate-like portions 31 respectively located on the upper, lower, left and right sides of the dust collector 3, the plate-like portions 31 (31a, 31b, 31c) located on the upper, left, and right are provided with sensors 33. Then, the obstacle information detected by the sensor 33 is sent to a control circuit provided in the dust collector 3, and the control circuit instructs the cylinder 36 to expand and contract according to the obstacle information detected by the sensor 33. The cylinder 36 expands and contracts based on this command. Therefore, when there is an obstacle while the dust collecting vehicle 1 is traveling, the introduction part 30 automatically opens and closes, so that the vehicle can travel smoothly and can travel a longer distance in a short time. A wide range of air can be cleaned, and the air can be efficiently cleaned. Further, as the traveling speed increases, more air flows from the introduction unit 30 toward the air discharge unit 25. However, since the sensor 33 detects an obstacle, the traveling speed can be increased even in a narrow place. It is possible to clean the air efficiently.
The sensor 33 may be provided in the driver's seat 2a or the structure 10, but the sensor 33 is mainly used to detect an obstacle so that the introduction unit 30 does not hit the obstacle. It is preferable to be provided in the introduction part 30 so that the distance between the part 30 and the obstacle can be measured accurately.
