Description

  The present invention relates to a smoke distribution system including a smoke smoking area that is divided into a non-smoking area and a smoking area and adjusts the flow velocity at the boundary so that dust contained in tobacco smoke does not flow from the smoking area to the non-smoking area.

  Conventionally, this type of smoke distribution system uses partitions to partition the smoking area and the non-smoking area, and in the indoor space provided with a passage so that they can come and go to each other, the air supply from the ceiling of the smoking area and the ceiling of the smoking area There is known a smoke distribution system that forms an air flow from a non-smoking area to a smoking area by exhausting air and that does not leak dust by ensuring sufficient ventilation airflow by other air blowing means. (For example, refer to Patent Document 1).

Hereinafter, the smoke separation system will be described with reference to FIGS. 16 and 17.
As shown in FIGS. 16 and 17, the smoke distribution system 101 includes a smoke distribution chamber 102 having a ventilation function, and a reflux device 103 installed in the smoke distribution chamber 102.

  The smoke chamber 102 is a space 80 surrounded by a floor 104, a ceiling 105, and four side walls 106. Further, the smoking area 102 divides a non-smoking area 108 and a smoking area 109 by a partition 107 that is vertically raised from the floor surface.

  An air supply port 111 is provided in the ceiling 105 in a region farthest from the partition on the non-smoking area 108 side, and an exhaust port 112 is provided in the ceiling 105 in a region farthest from the partition on the smoking area 109 side.

  The reflux device 103 is installed in the upper part of the passage 110 which can go back and forth between the non-smoking area 108 side and the smoking area 109 side. The reflux device 103 includes a ceiling 105 on the non-smoking area 108 side and a duct 114 straddling the ceiling 105 on the smoking area 109 side. The duct 114 forms an air passage 115 along the ceiling 105 in the smoke distribution chamber 102.

  At the end of the duct 114, a suction port 116 is formed on the upstream side of the air passage 115 located in the smoking area 109, and is opened from the ceiling 105 of the smoking area 109 toward the floor 104, for example. Further, an air outlet 117 is formed on the downstream side of the air passage 115 located in the non-smoking area 108, and is opened from the ceiling 105 of the non-smoking area 108 to the floor 104 in the vicinity of the passage 110, for example. Further, the filter 118 is disposed between the suction port 116 and the air outlet 117 inside the air passage 115.

  With the above configuration, the smoke distribution system 101 functions as follows.

  Air is supplied into the non-smoking area 108 from the air inlet 111 opened in the ceiling 105 on the non-smoking area 108 side, and the air in the smoking area 109 is exhausted from the exhaust port 12 opened in the ceiling 105 on the smoking area 109 side. .

  The main stream of air taken into the smoking area 108 from the air supply port 111 travels along the side wall 106 and the floor 104 of the smoking area 108 toward the passage 110. For this reason, as indicated by an arrow in FIG. 17, a first air flow F <b> 1 is formed in the smoking chamber 102 from the smoking area 108 side through the passage 110 toward the smoking area 109 side. Before or after forming the first air flow F1, or simultaneously with forming the first air flow F1, the fan 119 of the reflux device 103 is driven. When the fan 119 is driven, air in the smoking area 109 including tobacco smoke is sucked into the air passage 115 from the suction port 116 of the duct 114. The air sucked into the air passage 115 passes through the filter 118. The filter 118 removes the dust contained in the air, and the clean air from which the dust has been removed is blown into the non-smoking area 108 from the air outlet 117 of the duct 114 located near the upper part of the passage 110. That is, the suction of air in the smoking area 109 and the blowing of air into the non-smoking area 108 by the reflux device 103 are performed in the vicinity of the passage 110 serving as a boundary opening. As a result, a return air flow returning from the inside of the smoking area 109 to the inside of the non-smoking area 108 is formed in the ventilation path 115 of the reflux device 103. As a result, as indicated by an arrow in FIG. 15, a second air flow F <b> 2 is formed from the non-smoking area 108 side toward the smoking area 109 through the upper portion of the passage 110 at a position near the ceiling 105 in the upper part of the smoke chamber 102.

  By forming the airflows of F1 and F2 in this way, the flow rate of air from the non-smoking area 108 side to the smoking area 109 side in the smoking area 102 increases, and the airflow that flows backward through the passage 110 toward the non-smoking area 108 side. The occurrence of is reduced.

According to a first aspect of the present invention, there is provided a smoke distribution system including a structure that forms and arranges at least one passage at a boundary between a non-smoking area and a smoking area, a blower that forms the structure, and a non-smoking area. A smoke distribution system that forms an air flow from an air supply port to an exhaust port by an air supply port provided and an exhaust port provided in a smoking area,
The blower unit includes a housing containing a high-pressure air generating unit that sucks air from the non-smoking area side and generates high-pressure air, and a nozzle including a blow-out port that blows out the high-pressure air to the side part of the cylinder,
The plurality of nozzles are erected from the top surface of the housing toward the ceiling at the boundary, and an induction air passage is formed by a gap between the plurality of nozzles,
The smoke distribution system is characterized in that the air outlets of the plurality of nozzles are flush with each other so as to blow out from the air outlet toward the smoking area.

  As a result, the air flow formed from the non-smoking area side to the smoking area side at the area boundary between the non-smoking area and the smoking area can secure a predetermined wind speed, and the ceiling is used regardless of the height from the floor. Even if the height is high, the cigarette smoke does not reversely flow between the non-smoking area and the smoking area. In addition, since the area between the nozzles can be seen by providing a gap between the nozzles, there is an effect that smoke can be produced for 80 minutes in a space where a feeling of opening can be obtained as compared with a case where the space is partitioned by a wall such as a partition.

  The smoke distribution system according to claim 2 is such that the cross section of the nozzle of the blower section is the largest on the passage side, and gradually decreases as the distance from the passage increases, so that the wind speed blown from the nozzle is the highest on the passage side. It is.

  As a result, the air blown from the nozzle closest to the passage becomes the fastest, so that the amount of air drawn from the passage that can be said to be the widest induction gap can be increased to the same level as the amount of air drawn from other gaps. There is an effect that it is possible to provide a smoking area with a wind that has a more uniform wind speed with respect to the direction and suppresses discomfort caused by unevenness of the wind.

  According to a third aspect of the present invention, there is provided a smoke distribution system in which the air blowing section includes a chamber disposed to face the casing, and a duct having no air outlet in the cylinder, and the nozzle and the duct are spaced apart from each other. The nozzles and the ducts communicate with each other through one surface where the casing and the chamber face each other at both upper and lower ends of the duct, and one end of the nozzle is supplied with the high-pressure air from the casing. The other end is supplied with the high-pressure air from the casing through the duct and the chamber, and an air attraction air passage that is attracted to the air blown out from the outlet is formed by the gap.

  As a result, high-pressure air can be supplied from above the nozzle via the chamber, so that a uniform wind speed can be obtained at the top and bottom even when the nozzle height is increased. Since the air can be blown to the smoking area, the smoker has an effect of reducing discomfort caused by direct hitting of the wind.

  The smoke distribution system according to claim 4 is such that the cross-sectional area of the nozzle of the blowing means is larger on the chamber side than on the casing side.

  As a result, air is easily supplied from the chamber. Therefore, even when installed in a space with a high ceiling compared to ordinary houses, it is possible to obtain a flow rate that is blown from the upper nozzle, and a uniform wind speed at the top and bottom. Can be provided to the smoking area, so that there is an effect that a uniform wind can be provided to the smoking area regardless of the height.

  Further, the smoke distribution system according to claim 5 is provided with a wind direction adjusting means capable of directing the wind direction obliquely upward at the air outlet.

  As a result, an air flow linearly directed to the exhaust port can be formed, and the tobacco smoke passes between smokers and reaches the exhaust port as it moves obliquely upward with respect to the ground toward the exhaust port. Since smoke can be reduced, there is an effect that passive smoking among smokers can be suppressed.

  In addition, the smoke distribution system according to claim 6 has a mechanism for changing the length of the duct of the air blowing means.

  Thus, by changing the length of the duct according to the height of the ceiling, there is an effect that it can be used as a smoke distribution system that provides surface wind even when moved to a space having a different height.

  The smoke distribution system according to claim 7 has a mechanism for making the length of the nozzle and the length of the duct of the blowing means variable.

  Thus, by changing the length of the duct according to the height of the ceiling, there is an effect that it can be used as a smoke distribution system that provides surface wind even when moved to a space having a different height.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are examples embodying the present invention, and do not limit the technical scope of the present invention. In addition, throughout the drawings, the same portions are denoted by the same reference numerals, and the second and subsequent descriptions are omitted.

(Embodiment 1)
Initially, the structure of the smoke distribution system 1 which concerns on this Embodiment is demonstrated using FIG.

  As shown in FIG. 1, the smoke distribution system 1 is composed of a smoke distribution chamber 2 having a ventilation function and a structure 7 having a blower unit 3 installed in the smoke distribution chamber 2. The smoke compartment 2 is defined by a floor 4, a ceiling 5 and four side walls 6. The smoke compartment 2 is divided into a non-smoking area 8 and a smoking area 9 by a structure 7. The structure 7 is divided into two, and the passage 10 is formed between the two structures 7 arranged side by side. The passage 10 has a vertically long opening shape from the floor 4 to the ceiling 5 of the smoking area 2 so that a person can move between the smoking area 8 side and the smoking area 9 side.

  For example, three air inlets 11 are provided in the ceiling 5 on the non-smoking area 8 side. The air inlet 11 takes in fresh air outside the smoke chamber 2 into the non-smoking area 8. The air supply port 11 is arranged as far as possible from the structure 7. Further, the air inlets 11 are arranged in a row at intervals in the depth (D) direction in the non-smoking area 8.

  Further, for example, three exhaust ports 12 are provided in the ceiling 5 on the smoking area 9 side. The exhaust port 12 discharges the air in the smoking area 9 to the outside of the smoke compartment 2. The exhaust port 12 is arranged as far as possible from the structure 7. Further, the exhaust ports 12 are arranged in a row in the smoking area 9 in the depth (D) direction with a space therebetween.

  Therefore, the air supply port 11 and the exhaust port 12 constitute a ventilation unit that cooperates with each other to replace the air in the smoking chamber 2 with the air outside the smoking chamber 2.

  As shown in FIGS. 1 and 2, the structure 7 is provided at a position that partitions the non-smoking area 8 and the smoking area 9. The structure 7 has a blower 3. The blower unit 3 includes a housing 13 having a suction port 23 and a high-pressure air generation unit 19 that generates high-pressure air, and a nozzle 15 provided with a blow-out port 14 that blows high-pressure air to the side of the cylindrical body 20. A plurality of nozzles 15 are erected from the top surface of the housing 13 toward the ceiling 5. The plurality of nozzles 15 are arranged at equal intervals, and an induction air passage is formed by the gaps between the nozzles 15 (see the induction interval 44 in FIG. 5). The air outlets 14 of the plurality of nozzles 15 are arranged so as to be flush with each other. Moreover, the opening area of the blower outlet 14 is made equal.

  Further, for example, an internal air passage 16 is formed inside the plurality of nozzles 15 as shown in FIG.

  The high-pressure air generated by the high-pressure air generation unit 19 passes through the internal air passage 16, travels toward the air outlet 14, and blows out from the air outlet 14 toward the smoking area 9 side.

  A wind direction adjusting rib 21 is formed in the vicinity of the air outlet 14. The cross section of the blower outlet 14 is attached in the vicinity of the blower outlet 14 so as to increase as it goes upward. In the lower part close to the high-pressure air generating part 19, the high-pressure air from the lower high-pressure air generating part 19 has a strong tendency to blow upward, so that the tip of the wind direction adjusting rib 21 faces the ground far away in the blowing direction. It is attached. However, an angle formed by a straight line connecting a point on the ground to which the tip of the wind direction adjusting rib 21 is directed and an angle formed by the ground (an incident angle of the airflow to the ground) does not exceed 60 degrees. The ground is a flat surface with no inclination. By doing so, high-pressure air is blown out parallel to the ground. In this way, the wind of the surface where the wind speed is equal is blown out to the smoking area 9 side.

  According to the above configuration, in the smoke distribution system 1, air is supplied into the non-smoking area 8 from the air supply opening 11 opened in the ceiling 5 on the non-smoking area 8 side, and the exhaust opening opened in the ceiling 5 on the smoking area 9 side. The air in the smoking area 9 is exhausted from 12. The main stream of air taken into the smoking area 8 from the air supply port 11 travels along the side wall 6 and the floor 4 on the smoking area 8 side toward the passage 10.

  A part of the air in the non-smoking area 8 side is taken in by the structure 7 at the boundary between the non-smoking area 8 and the smoking area 9, and is formed from the nozzle 15 extending vertically to the vicinity of the top of the casing to the vicinity of the ceiling. A uniform air flow is formed.

  As a result, an air flow from the non-smoking area 8 to the smoking area 9 is formed at the boundary between the non-smoking area 8 and the smoking area 9 by the air flow formed by the air supply port 11 and the exhaust port 12 and the air flow by the structure 7. After that, the air blown out from the structure 7 travels straight in parallel with the ground, and then gradually forms an air flow toward the exhaust port 12 as it moves away from the nozzle 15.

  Therefore, even if the ceiling 5 at the area boundary is high, the tobacco smoke generated in the smoking area 9 does not flow back to the smoking area 8, but is separated from the floor 4 to the ceiling 5 by the air flow formed without dust leakage. It can be performed.

  Moreover, since the structure 7 can see through each other area from the gaps between the plurality of nozzles 15, it is possible to perform smoke separation that can provide a sense of openness as compared with a structure partitioned by a wall such as a partition.

  In addition, it is possible to save the time and effort of maintenance of the filter, which is necessary when the air flow cannot be ensured due to the clogging of the filter or the dust leakage occurs.

(Embodiment 2)
Hereinafter, the configuration of the second embodiment of the present invention will be described in detail with reference to FIG. 3 and FIG.

  The smoke distribution system 1 according to the second embodiment increases the amount of the induced air flow 22 formed in the passage of the smoke distribution system 1 according to the first embodiment, thereby achieving a uniform flow velocity in the depth (D) direction. It is. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  That is, as shown in FIGS. 3 and 4, the nozzle 15 of the blower 3 of the structure 31 is formed so that its cross-sectional area gradually increases as it approaches the passage 10 side.

  According to the above configuration, since the opening area of the air outlet 14 is equal and only the cross-sectional area of the nozzle 15 is different, the blown air flow 18 is closest to the passage 10 and is the fastest with the nozzle 15 having the largest cross-sectional area. The induced air flow 22 formed in step (1) is made to have a wind speed equivalent to the induced air flow 17 formed by the gap between the nozzles (attraction interval 44), and the air flow is uniform in the depth direction. Can be formed. Therefore, as shown by the broken line in FIG. 4, the air flow velocity in the depth (D) direction can be made uniform between the side walls 6 facing in the depth (D) direction at the boundary between the smoking area 8 and the smoking area 9.

  In this manner, the user of the smoking area 9 can perform smoke separation without discomfort due to the provision of a wind with uneven wind speed.

(Embodiment 3)
Hereinafter, the configuration of the second embodiment of the present invention will be described in detail with reference to FIGS. 5 and 6.

  Even if the height (H) of the ceiling 5 of the smoke distribution system 1 according to the first and second embodiments is high, the smoke distribution system 1 according to the third embodiment does not decrease the upper flow velocity, and the air has a more uniform flow velocity in the vertical direction. It is intended to form a flow. In the third embodiment, the same components as those in the first and second embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  That is, as shown in FIG. 5, the structure 41 includes a nozzle 15, a duct 42 provided side by side, and a chamber 43 provided in the upper part. Ducts 42 are provided between the nozzles 15 and the respective nozzles 15, are connected to the high-pressure air generator 19 at the lower ends of the nozzles 15 and the ducts 42, and are connected to the chamber 43 at the upper ends. The duct 42 guides the high-pressure air generated by the high-pressure air generator 19 to the chamber 43. The chamber 43 has a volume that is at least twice as large as the total internal volume of the nozzle 15 and the duct 42.

  According to the above configuration, the high-pressure air generated by the high-pressure air generation unit 19 goes to the nozzles 15 and the ducts 42 arranged alternately with the nozzles 15, and the air going to the nozzles 15 is provided on the side surfaces of the nozzles 15. The air is blown out from the air outlet 14. Further, as shown in FIG. 6, the air traveling toward the duct 42 passes through the duct 42 and reaches the chamber 43, and then travels from the chamber 43 toward the nozzle 15. 6 shows a cross section (a) cut at the position of one nozzle 15 of the plurality of nozzles 15 of the structure 41 and a cross section (b) of the upper part of one duct 42 of the plurality of ducts 42. Is drawn in parallel. The broken line shows the position of the same height.

Thereby, the flow velocity of the air blown out from the nozzle 15 can be made uniform regardless of the height of the structure 41. Therefore, even if the length of the nozzle 15 is increased, the flow velocity does not decrease toward the ceiling 5, and the uniform flow velocity is maintained. The air flow can be formed with respect to the smoking area 9. Further, similarly to the first embodiment, the formation of the induced air flow 17 and the space between the non-smoking area 8 and the smoking area 9 can be seen by the gap (attraction interval 44) between the nozzle 15 and the duct 42, and the effect is not closed. Also have.
(Embodiment 4)
Hereinafter, the configuration of the fourth embodiment of the present invention will be described in detail with reference to FIG.

  The smoke distribution system 1 according to the fourth embodiment is intended to form an air flow having a uniform wind speed over the entire smoking area 9 of the smoke distribution system 1 according to the third embodiment. In the fourth embodiment, the same components as those in the first to third embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  That is, as shown in FIG. 7, the structure 51 is such that the cross-sectional area of the nozzle 15 of the structure 41 of the third embodiment is larger on the chamber 43 side than on the housing 13 side. .

  According to the above configuration, since air is easily supplied from the chamber 43, the amount of air blown from the upper nozzle 15 can be increased even when the length of the nozzle 15 is very long.

  In addition, since the flow generated by the air supply port 11 and the exhaust port 12 normally flows near the floor 4 at the boundary between the non-smoking area 8 and the smoking area 9, the flow velocity increases near the floor 4. By using the structure 41 according to the fourth embodiment of the present invention in combination with the phenomenon that the flow velocity increases near the floor 4, an air flow with a large amount of air blown from the upper nozzle 15 formed by the structure 41 is used. And an air flow having a high flow velocity in the vicinity of the floor 4 can be combined to form an air flow having a uniform flow velocity in the height (H) direction. With regard to the depth (D) direction, a uniform air flow can be formed by adopting a structure in which the cross-sectional area gradually increases as it approaches the side of the passage 10 shown in the second embodiment. Therefore, an air flow having a uniform wind speed can be formed in both directions of height (H), depth (D), and uniform wind speed can be formed at the boundary between the non-smoking area 8 and the smoking area 9 over the entire smoking area 9. Therefore, it is possible to form a comfortable air flow that suppresses uneven wind speed for the user on the smoking area 9 side.

In addition, by forming the air flow at a uniform wind speed, the flow rate is slow and the portion where the tobacco smoke accumulates on the smoking area 9 side is reduced. That is, it is possible to suppress the accumulation of smoke in the vicinity of the floor 4, the ceiling 5, the side wall 6, and the partition, and the generation of a foul odor due to contamination.
(Embodiment 5)
Hereinafter, the configuration of the fifth embodiment of the present invention will be described in detail with reference to FIGS. 8, 9, 10, and 11. FIG.

  The smoke distribution system 1 according to the fifth embodiment is intended to reduce the passive smoking of smokers in the smoking area 9 of the smoke distribution system 1 according to the first to fourth embodiments. Note that in the fifth embodiment, the same components as those in the first to fourth embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  That is, the structure 61 shown in FIGS. 8 and 9 includes a wind direction adjusting rib 62 used for air flow rectification provided inside the air outlet 14 and an angle varying mechanism 63 that adjusts the blowing angle of the wind direction adjusting rib 62. Is.

  As shown in FIG. 10, the angle variable mechanism 63 has a width at the tip of the air direction adjusting rib 62 determined in accordance with the opening of the air outlet 14, is attached to the internal air passage 16, and rotates about the axis A. The tip of the wind direction adjusting rib 62 moves up and down along the air outlet 14.

  According to the above configuration, since air flows along the wind direction adjusting rib 62, if the direction is adjusted so that the tip of the wind direction adjusting rib 62 faces the exhaust port 12, it is obliquely upward from the structure 61 toward the exhaust port 12. An air flow can be formed. As shown in FIG. 11, the cigarette smoke 54 produced by the smoker travels in parallel with the ground in the vicinity of the smoker's face because the cigarette smoke 54 travels toward the exhaust port 12 on the diagonally upward airflow formed by the structure 61. The amount of cigarette smoke 54 can be suppressed, and passive smoking between smokers is reduced.

Further, by forming an air flow obliquely upward, the tobacco smoke 54 moving along the wall surface can be collected around the exhaust port 12. That is, smoke accumulates near the floor 4, the ceiling 5, and the side wall 6, and the range where it becomes dirty and emits a bad odor can be narrowed around the exhaust port 12.
(Embodiment 6)
Hereinafter, the configuration of Embodiment 6 of the present invention will be described in detail with reference to FIGS. 12, 13, 14, and 15. FIG.

  The smoke distribution system 1 according to the sixth embodiment makes at least the length of the nozzle 15 of the blower 3 of the structure 7 of the smoke distribution system 1 according to the first to fifth embodiments variable. Note that in the sixth embodiment, the same components as those in the first to fifth embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  That is, as shown in FIG. 12, the structure has a pull-out nozzle 73 capable of pulling out the nozzle 15 and the duct 42 of each structure 71 by the variable length mechanism 72 as shown in FIG.

  As described above, the nozzle 15 of the structure 71 includes the drawing nozzle 73 that is drawn out when the length is changed, in addition to the normal nozzle 15. Here, when increasing the length, the lower nozzle is the lower nozzle and the upper nozzle is the upper nozzle. Here, the upper nozzle is referred to as the drawing nozzle 73. The lower nozzle is here a nozzle 15.

  The variable length mechanism 72 is disposed across the drawing nozzle 73 (upper nozzle) and the nozzle 15 (lower nozzle).

  As shown in FIG. 14, in the extraction nozzle 73 (upper nozzle), the variable length mechanism 72 is a groove 75 and a protrusion 77 provided on the back surface of the extraction nozzle 73 (upper nozzle).

  The groove 75 is formed from the lower end to the upper end except for both ends of the extraction nozzle 73 in the direction in which the extraction nozzle 73 extends, and the protruding portion 77 is intermittently formed from end to end inside the groove 75. Yes. Further, the protrusion 77 of the groove 75 has an upper surface that is an inclined surface that smoothly falls outward from the groove 75, and a lower surface that is a flat surface.

  Further, as shown in FIG. 15, in the nozzle 15 (lower nozzle), the length varying mechanism 72 is formed in a portion near the upper end, and a button 74 positioned outside the nozzle 15 and inside the nozzle 15. The projection 76, the spring 78, the intermediate member 79, and the space 80 are positioned.

  The intermediate material 79 is a plate having a button 74, and a protrusion 76. The button 74 is provided on the back side, and the protrusion 76 protrudes into the nozzle 15 below the nozzle 15 than the button 74. The space 80 is a groove dug in the inner wall on the back side of the nozzle 15 and houses the intermediate member 79 and the spring 78.

  The spring 78 presses the intermediate member 79 between the inner wall of the space 80 and the intermediate member 79, thereby causing the button 74 to protrude to the outside (back side) of the nozzle 15 and the protrusion 76 to protrude to the inside of the nozzle 15. .

  The intermediate member 79 is a plate having a step that shifts from the outside to the inside of the nozzle 15 between the button 74 and the protrusion 76, and the plate can be rotated at the step.

  Further, the button 74 has a structure that proceeds horizontally toward the inside of the nozzle 15 by applying a horizontal force from the outside. The pressing operation of the button 74 can be interlocked with the protrusion 76 side at the step portion.

  Further, the upper end of the protrusion 76 is a flat surface, and when the button 74 is not pressed, the upper end flat surface of the protrusion 76 comes into contact with the lower end flat surface of the protruding portion 77 of the groove 75 of the extraction nozzle 73. It has become.

  According to the above configuration, when the button 74 is pressed, the protrusion 76 is retracted and the pull-out nozzle 73 can be extended. Further, when the flat surface at the upper end of the protrusion 76 contacts the flat surface at the lower end of the protruding portion 77 of the groove 75 with respect to the pull-out nozzle 73 that tends to fall down by its own weight, the pull-out nozzle 73 is fixed. That is, after the pull-out nozzle 73 is stretched, the pull-up nozzle 73 can be kept moving downward by determining the length by hooking the flat surface at the upper end of the protrusion 76 onto the flat surface at the lower end by gravity. The force of the spring 78 can firmly fix the contact between the upper end plane of the protrusion 76 and the lower end plane of the protrusion 77 of the groove 75 of the extraction nozzle 73. Further, if the projection 76 is retracted while the button 74 is pressed, the drawing nozzle 73 can freely move.

  Thus, as shown in FIG. 14, the pull-out length of the pull-out nozzle 73 can be retracted by pushing the button 74 of the variable length mechanism, and the groove 75 at the position of the desired length can be retracted. It can be used according to.

  In other words, when it is desired to shorten the length, by pushing the button 74 and retracting the projection 76 inside, the projection 76 against the plane at the lower end of the projection 77 can be prevented from being caught, and the length of the extraction nozzle 73 can be shortened. it can.

  By such an action, there is an effect that it can be used even if it moves to a space 80 having a different height (H). This effect is shown both when the structure 71 is used in a fixed manner and when the structure 71 is moved and used everywhere.

  The smoke distribution system according to the present invention is useful as a smoke distribution system capable of producing a space smoke that provides a feeling of openness compared to a system in which cigarette smoke does not flow backward between areas even when the ceiling is high and is partitioned by a wall such as a partition.
