Description

  The present invention relates to a smoking booth and other spaces that allow smoking (hereinafter referred to as “smoking room” in the present invention), and further relates to a wall member used in a smoking room.

  In recent years, due to the enforcement of the Health Promotion Law, smoking is allowed only in limited spaces in public facilities. In many cases, smoking rooms for smoke separation are formed in buildings. Here it is important not to let the cigarette smoke leak out of the smoking room. Further, in the smoking room, it is desired that the smoke of the cigarette does not adhere to the clothes and that the smoker does not inhale more smoke than required by the smoker.

  On the other hand, for example, when an attempt is made to provide a smoking room in an existing building in consideration of smoke separation, it is difficult to perform exhaust processing, for example, laying of an exhaust duct. Existing pipes, ducts, and cables are routed vertically and horizontally behind the ceiling, and must be bypassed. This problem is also common when trying to keep the construction costs low by reducing the height of the ceiling in new buildings. Even if an air purifier is installed in the smoking room and the smoke is purified and circulated, the effect is limited, and exhaust treatment is inevitable in consideration of the smoker's amenity.

  In addition, building managers also want to save energy by reducing exhaust fan and other power costs.

  As a result of the applicant's prior art search, (1) an air blower provided near the ashtray generates an upward air flow and exhausts it from an opposing exhaust port (Patent Document 1), (2) a smoker's feet An air purifier equipped with an air outlet near the ceiling and a suction port near the ceiling is installed, and a plurality of mini-blowers that generate upward airflow are installed on the table (Patent Document 2) and (3) A blower top suction air purifier is used to find that the ratio of the supply air amount and the exhaust air amount of the lower blowout of the suction air volume is diverted to 1: 4 (the suction amount is 5 times the blowout amount) (Patent Document 3) It was done. In addition, about the "shielding body" as a component of this invention, invention of the service station which partitions off a non-smoking room space and a smoking space by the hanging wall hanging down from the ceiling is also disclosed (patent document 4).

  However, the above inventions (1) to (3) are based on the premise that the smoker smokes at a fixed position. In practice, smokers rarely stay in a fixed position, such as having a conversation between smokers or walking in a smoking room for exercise. This situation is conspicuous in smoking rooms where chairs are not installed for space saving and other reasons. In the inventions of (1) to (3) described above, costs such as a mini blower and an air purifier are required. Furthermore, it does not disclose the flexibility in replacing the existing building.

  The object of the present invention is to consider the amenity of smokers in smoking rooms and to save them, and to prevent smoke leakage from smoking rooms to non-smoking rooms without forcing the smokers to sit down and The purpose is to provide low-cost equipment that can flexibly cope with the reordering.

  On one wall of the smoking room that is partitioned by four wall surfaces, air is supplied toward the room at a wind speed of 0.3 to 0.7 m / sec below the height position of the ashtray, and above the height position of the ashtray. Exhaust air is generated so that the air supplied toward the room is reversed and exhausted in a direction toward the one wall without generating any other auxiliary air flow, and the ashtray is placed on the table. There is provided a method for ventilating a smoking room, characterized in that the air is supplied below the table and exhausted above the table.

Further, on one wall surface of the smoking room that is partitioned by the four wall surfaces and the other wall surface facing the one wall surface, the room is directed indoors at a wind speed of 0.3 to 0.7 m / sec below the height position of the ashtray. The air supplied to the room without any other auxiliary air flow is supplied to the one wall surface or the other wall surface. Smoking room ventilation method, wherein the ashtray is arranged on a table, and air is supplied below the table and exhausted above the table. Is provided.

  Smoke can be quickly removed from the room by the reverse airflow without causing the smoker in the room to feel the draft by the low-speed blowout. Even if the occupant does not stay in the predetermined position, the smoke is discharged by being attracted by the reverse airflow. “Supplying air toward the room at a wind speed of 0.3 to 0.7 m / sec” means that the wind speed measured on the air supply surface (opening surface) of the air supply port is 0.3 to 0.7 m / sec. It means that. Usually, the wind speed measured on the air supply surface is, for example, 2 m / sec, but a blowout at a low speed of 0.3 to 0.7 m / sec is employed. Furthermore, since the air supply port and the exhaust port are provided on the same wall surface, duct work and other constructions are easy and space can be used effectively. Furthermore, it contributes to energy saving by low-speed blowing. The “smoking room” refers to a room that allows smoking, such as a smoking booth in which a temporary partition or a vinyl curtain divides the space, a karaoke room, a reception room, and other smoking spaces in restaurants. “Without other auxiliary airflow generation” means that the airflow generation in the smoking room is substantially supplied by air supply and exhaust on one wall surface or one wall surface of the smoking room and the other wall surface facing the one wall surface. It is. That is, it does not mean bringing an auxiliary blower such as the mini blower in Patent Document 2 into the smoking room. Furthermore, the “height position of the ashtray” refers to a height position where the cigarette is placed (a height position where smoke is generated from the cigarette). The ashtray includes a stand-type ashtray.

  A configuration in which the air supplied toward the room passes through the upper and lower sides of the shield provided on the ceiling portion of the smoking room while being exhausted by being reversed in the direction toward the one wall surface or the other wall surface. It is also good. An example of the shield is a hanging wall. According to the knowledge of the present inventors, it has been visually confirmed that smoke vortices are generated near the indoor ceiling when the shield is not installed on the ceiling. If this stays, there is a risk of smoke adhering to the smoker's head. Therefore, the present inventors have succeeded in preventing smoke vortex retention by providing a shield on the ceiling of the room. Further, it has been found that even if the occupant in the smoking room moves away from the position of the ashtray, for example, exhaust is effectively performed by the reverse flow due to suction from the exhaust port and the wind path around the shield.

According to the present invention, on one wall surface of the smoking room that is partitioned by the four wall surfaces, an air supply port for supplying a strip-shaped or linear airflow that is long in the width direction is provided below the height position of the ashtray, An exhaust port for exhausting air from substantially the entire surface is provided above the height position of the ashtray, a table for disposing the ashtray is provided on the inner surface of the one wall surface, an air supply port is provided below the table, and an exhaust port is provided above the table There is provided a smoking room characterized in that the opening ratio of the exhaust ports arranged in a distributed manner above the table is small at the top and large at the bottom .

Further, according to the present invention, in one wall surface of the smoking room that is partitioned by the four wall surfaces and the other wall surface facing the one wall surface, a strip or line shape that is long in the width direction below the height position of the ashtray Each of which is provided with an air supply port for supplying the air flow, and an exhaust port for exhausting from substantially the entire surface is provided above the height position of the ashtray, and the inner surface of the one wall surface and / or the inner surface of the other wall surface A table for arranging the ashtray is provided, an air supply port is provided below the table, an exhaust port is provided above the table, and the opening ratio of the exhaust ports arranged above the table is small above the table. A smoking room is provided, characterized in that it is enlarged below .

  According to the present invention, since the air supply port and the exhaust port are set based on the position where the cigarette smoke normally occurs, the cigarette smoke is quickly discharged to the outside by the reverse flow together with the fresh air. In other words, it can be ventilated with a small air volume, contributing to energy saving. Note that “supplying a strip or linear airflow that is long in the width direction” means that the supply air is blown into the room in a horizontally long shape that is long in the width direction. That is, like so-called replacement ventilation, the air flow over the floor is blown out toward the opposite surface of the smoking room. The air supply port may be an opening continuous in the width direction or may be intermittent. Further, a swirl flow forming mechanism (see Japanese Patent Application Laid-Open No. 2002-372268) sold by the applicant under the trade name “SWIT” may be used. The “exhaust port for exhausting air from substantially the entire surface” refers to a configuration that allows exhaust from substantially the entire surface of the wall surface above the ashtray, such as punching and air-permeable material described later.

  The other wall surface opposite to the one wall surface provided with the air supply port and the exhaust port can also be constituted by a wall surface provided with the air supply port and the exhaust port, and can be a symmetrical surface. If it does in this way, it will be advantageous for constructing a wide smoking space because both the two opposing surfaces of the chamber are the air supply / exhaust surfaces.

  Moreover, you may provide the shielding body substantially parallel to the said one surface in the ceiling part of a smoking room. The shield is positioned between the one wall surface and the opposing surface, and is installed substantially parallel to the one wall surface. The “opposing surface” is a non-breathable wall or a surface configured in the same manner as the one wall surface. If it does so, it can prevent over the width direction that the whirlpool of smoke stays in the ceiling part vicinity.

  The shield may be slightly inclined, and the installation means may be supported by a legged stand in addition to hanging. The height of the lower end is higher than the height of the respiratory organ when the smoker in the room stands, and preferably higher than the position of the head does not interfere with the movement. Moreover, when the edge part covers a door, it is necessary to make it higher than the height of the door.

  An open space may be provided between the shield and the ceiling of the smoking room. If it does so, smoke will distribute | circulate between a ceiling and a shield, and the stay of a vortex can be prevented more effectively.

Further, an air supply chamber may be formed below the table and an exhaust chamber above the table at the back of the one wall surface and / or the back of the other wall surface. Further, a saddle duct that communicates with one or both of the air supply chamber and the exhaust chamber may be provided on a side end of the one wall surface and / or the other wall surface. With this configuration, the workability can be improved by bringing the air supply / exhaust source close to the wall surface having the air supply / exhaust function. In addition, the saddle duct may be open at the bottom and closed above the opening. If comprised in this way, it can apply to the floor blowing system which is spreading. In other words, the air supplied from the air supply source of the system can be used as it is from the air supply port of the smoking room without using any other power. Furthermore, the lower end of the soot duct may be closed at the height of the floor of the smoking room, the upper end of the soot duct may be open, and the soot duct may be communicated with the air supply chamber below the table. .

Further, according to the present invention, a table for placing an ashtray on the inner surface of the wall surface is provided, an air supply port is provided below the table on the wall surface, an exhaust port is provided above the table, and the back of the wall surface is below the table. An air supply chamber is formed, an exhaust chamber is formed above the table, and the opening ratio of the exhaust ports arranged above the table is small at the top and large at the bottom. A wall member is provided. A saddle duct that communicates with one or both of the air supply chamber and the exhaust chamber may be provided at a side end of the wall surface. Furthermore, the lower end of the saddle duct may be closed, the upper end of the saddle duct may be opened, and the saddle duct may communicate with the air supply chamber below the table.

  In addition to the above-described advantages, this structure is provided with a table for arranging an air supply / exhaust function and an ashtray, and a smoking room can be easily formed as a prefabricated member simply by being built.

  According to the present invention, it is possible to prevent smoke from leaking from a smoking room to a non-smoking space while taking into account the smoker's amenity. Smoking rooms that can be flexibly adapted to reordering can be provided at a low price.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted. FIG. 1 is an exploded perspective view of a smoking room 1 according to an embodiment of the present invention. The smoking room 1 is surrounded by four wall surfaces 10a, 10b, 10c, and 10d and surrounded by a ceiling surface 11 and a floor surface 12 to form a partitioned space for smoking.

  In the illustrated smoking room 1, a door 15 is provided on a wall surface 10a located on the left back side. A smoker can enter and leave the smoking room 1 by opening and closing the door 15. When the door 11 is closed, air does not leak out from the inside of the smoking room 1.

  The wall surface 10c located on the right front side in FIG. 1 and the wall surface 10d located on the left front side, the ceiling surface 11 and the floor surface 12 are substantially closed surfaces that do not allow air to flow from the inside of the smoking room 1 to the outside. Yes. The wall surfaces 10c and 10d may be a glass surface, for example, but may be formed of a sandwich panel similar to the wall surface 10b described later.

  On the other hand, a table 21 on which the ashtray 20 is placed is provided on the inner surface of the wall surface 10b located on the right back side in FIG. The ashtray 20 may be fixedly disposed on the table 21. The table 21 is provided in the vicinity of the smoker's waist at a depth of 400 mm in the indoor direction and the full width of the wall surface 10b. In this embodiment, the height of the table 21 is set to 900 mm above the floor with respect to the smoking room 1 having a height of 2500 mm.

  In the wall surface 10 b, an air supply port 25 is provided below the table 21, and an exhaust port 26 is provided above the table 21. Thus, the air supply port 25 is positioned below the height position of the ashtray 20 disposed on the table 21, and the exhaust port 26 is positioned above the height position of the ashtray 20.

  The air supply port 25 has a slit shape that is long in the width direction at the lower portion of the wall surface 10b. In this embodiment, two slit-shaped air supply ports 25 having a width of 700 mm are arranged at a position of 100 mm on the floor with an interval of 500 mm.

  Above the table 21, the wall surface 10b has an exhaust port 26 formed of a large number of circular holes distributed and formed as a whole. Similarly to the wall surface 10b below the table 21, the wall surface 10b may be a sandwich panel above the table 21, and a number of exhaust ports 26 may be opened on the inner wall surface. In the embodiment, the inner wall surface of the wall surface 10 b is formed of the punching metal 27 above the table 21. As described above, the wall surface 10b formed of the punching metal 27 above the table 21 has an opening ratio that is small at the top and large at the bottom. In this embodiment, the diameter of the exhaust port 26 formed in the punching metal 27 is 6φ and the aperture ratio is 20% at a height of 800 mm from the table 21, and the punching metal 27 is formed at a height higher than that. The exhaust port 26 has a diameter of 2.5φ and an aperture ratio of 20%.

  The lower part of the wall surface 10b is a sandwich panel composed of two front and rear plate members, and the upper part of the wall surface 10b is a sandwich panel in which the inner wall surface of the two front and rear plate members is a punching metal 27. An air supply chamber 30 is formed below the height position of the table 21, and an exhaust chamber 31 is formed above the height position of the table 21 at the back portion of 10 b. The aforementioned air supply port 25 communicates with the air supply chamber 30, and the aforementioned air exhaust port 26 communicates with the exhaust chamber 31. The interior of the wall surface 10b formed of the sandwich panel is partitioned vertically by the height of the table 21 using an appropriate partition member, so that an air supply chamber 30 is formed below and an exhaust chamber 31 is formed above. . In this embodiment, the width of the air supply chamber 30 and the exhaust chamber 31 is 2500 mm.

  At the side end portion of the wall surface 10b (the corner portion where the wall surface 10b and the wall surface 10a intersect), a soot duct 35 for introducing conditioned air from the back of the ceiling and supplying the air into the smoking room 1 is provided. The soot duct 35 has a triangular cross section and is erected at the corner of the smoking room 1. In this embodiment, the side length of the saddle duct 35 (triangular shape) at the position in contact with the wall surface 10b is 400 mm. According to this configuration, the width of the soot duct 35 is not taken compared with the supply air volume, and the room can be used effectively without a feeling of pressure on the smoker.

  The lower end of the soot duct 35 is closed at the height of the floor of the smoking room 1, and the upper end (upstream side) of the soot duct 35 is opened, and conditioned air generated by the air conditioner is received in the soot duct 35. The soot duct 35 communicates with the air supply chamber 30 below the table 21, so that the conditioned air received in the soot duct 35 is long or wide in the width direction from the air inlet 25. The air is fed into the smoking room 1. Although the inside of the eaves duct 35 is a cavity in order to use the air blowing power of the air conditioner, if the static pressure is insufficient, a cross flow fan may be installed in the eaves duct 35 or on the ceiling, if necessary. Then, air is supplied into the smoking room 1 at a low speed of 0.5 to 0.7 m / sec (0.5 m / sec in the present embodiment).

  Exhaust ducts 40 for discharging air contaminated with tobacco smoke in the smoking room 1 are connected to a plurality of locations on the upper surface of the exhaust chamber 31. Above the table 21, the wall surface 10 b is composed of the punching metal 27 in which the exhaust ports 26 are formed in an overall distribution. Therefore, the air contaminated with the cigarette smoke in the smoking room 1 is moved above the table 21. In FIG. 2, the air is sucked into the exhaust chamber 31 from almost the entire wall surface 10b and exhausted to the exhaust duct 40.

  This exhaust is performed at a lower speed than the supply air velocity (0.3 to 0.7 m / sec) on the suction surface (wall surface 10b) of the exhaust port 26, for example, 0.1 to 0.3 m / sec (this embodiment) In this embodiment, the air is sucked at an average of 0.2 m / sec). Further, by making the exhaust amount larger than the air supply amount, the inside of the smoking room 1 is kept at a negative pressure and the leakage of contaminated air to the outside is avoided.

  Further, one of the features of the present invention is that the smoker who walks around the smoking room 1 does not feel the environmental deterioration so much and avoids leakage of contaminated air to the outside. A means for this is a hanging wall 45 as a shield provided on the ceiling of the smoking room 1. The drooping wall 45 is made of a plate member arranged substantially in parallel with the wall surface 10b where the air supply port 25 and the exhaust port 26 are provided, and flows toward the exhaust port 26 (the wall surface 10b) above the smoking room 1. Arranged to partially block air. An open space 46 is provided between the hanging wall 45 and the ceiling 11 of the smoking room 1. In the present embodiment, a plate made of a steel plate having a height of 250 mm is suspended by a bolt through a metal fitting as the hanging wall 45, and a gap of 50 mm in height (between the upper end of the hanging wall 45 and the ceiling surface 11 ( An open space 46) is provided. The material of the hanging wall 45 may be, for example, a vinyl curtain with a weight, a stainless steel plate, or an acrylic plate, and the open space 46 may be formed by directly attaching an upper portion of these to the ceiling 11. . Note that the position of the drooping wall 45 is substantially the entire width direction between the wall surface 10b where the air supply port 25 and the exhaust port 26 are formed and the wall surface 10d facing the wall surface 10b (in the present embodiment, the position of 950 mm with respect to the depth of 1850 mm). It is drooping to. And the lower end is arrange | positioned above a smoker's head (in this Embodiment, the position of height 2200mm with respect to ceiling height 2500mm).

  In the smoking room 1 configured as described above, the supply air is blown from the supply port 25 below the table 21 at a low speed of 0.3 to 0.7 m / sec. By sucking in uniformly from the mouth 26, the air supplied toward the inside of the smoking room 1 is reversed in the direction toward the wall surface 10b to form a reversal flow sucked into the exhaust port 26, and the smoking room 1 with a small number of ventilations. It becomes possible to ventilate the inside. In the system having an air supply port and an exhaust port on the ceiling surface, the ventilation frequency is 60 times, but according to the smoking room 1 of the embodiment of the present invention, the ventilation frequency is reduced to 20 times. Reducing the number of ventilations will contribute to energy savings, reduce the size of the ducts, and reduce both equipment and operating costs.

  In addition, as for the size of the air supply duct (exhaust duct), it is possible to use a spiral duct having a diameter of 300 and a diameter of 175 in the conventional method. As a result, the beam of the duct can be penetrated, which contributes to the fit and simplifies the duct work. Furthermore, since it sucks in the substantially whole surface above exhaust chamber 31 at low speed, it does not make a smoker feel a draft.

  Further, the opening ratio of the exhaust ports 26 distributed above the table 21 is small in the upper part (position away from the table 21) and larger in the lower part (position close to the table 21). Most of the smoke smoked in the vicinity of the upper surface 21 is quickly discharged. In addition, cigarette smoke including hot air is diluted with fresh air from below while being raised to the ceiling, and is sucked into the exhaust port 26. Further, inside the exhaust chamber 31 constituted by a sandwich panel or the like, a reinforcing material is attached in a cross shape (see FIG. 2), and these serve as ventilation resistance, but the opening ratio of the exhaust port 26 is upward. Therefore, the air is sucked into the entire wall surface 10b above the table 21 without deviation.

  In addition, the smoker may walk and move in the smoking room 1. In such a case, as it is, smoke leaks between the wall surfaces 10a, 10b, 10c, and 10d of the smoking room 1 or through the gaps between the ceiling 11 and the floor 12 and the wall. However, if the hanging wall 45 is provided in the middle of the air supplied into the smoking room 1 flowing toward the punching metal 27 serving as the exhaust port 26, the flow path is throttled at the lower portion of the hanging wall 45, and the return flow rate is high. As a result, the inventor's experiment revealed that the smoke that floated flows toward the punching metal 27. However, at the same time, it was also found out that smoke was accumulated in the vicinity of the hanging wall 45 and stayed, and the inventors further worked on this solution. This is because the staying air in the upper part of the smoking room 1 and in the vicinity of the hanging wall 45 may be leaked when the door 15 is opened or closed when entering or leaving the room or when the supply and exhaust of the smoking room 1 is stopped. Therefore, the inventors have found that an open space 46 through which air can flow is provided above the hanging wall 45. The upper opening (open space 46) allows smoke accumulated on the opposite side of the hanging wall 45 to the exhaust port 26 to escape toward the exhaust port 26. However, if the opening (open space 46) is too large, the smoke pool is conversely large. As a result, it has been found that half or less of the height of the hanging wall 45 is most preferable (in this embodiment, 1/6 height of the hanging wall 45). In this way, the smoker and his / her clothing are exposed to a one-way flow of smoke, minimizing the effects of smoke and almost no smoke leakage outside the room.

  Although FIG. 1 shows a form in which the air supply source and the exhaust destination are communicated from the back of the ceiling, the present invention can also be applied to a floor blowing type air conditioning system. In other words, a floor blowing air conditioning system generally supplies conditioned air from a double floor space from a floor outlet provided on the floor (possibly via a carpet) and exhausts it to the back of the ceiling. The present invention can also be applied to a simple floor blowing air conditioning system. This will be described with reference to FIG.

  In the smoking room 1 ′ shown in FIG. 2, the wall surface 10 b and the other wall surface 10 d facing the wall surface 10 b have the same configuration as the wall surface 10 b in the embodiment described above with reference to FIG. A sandwich panel structure (with an inner wall surface above the table 21 being a punching metal 27) having a mouth 26 and having an air supply chamber 30 below the table 21 and an exhaust chamber 31 above the table 21 in the back is formed.

  In this smoking room 1 ′, the side surfaces of the wall surfaces 10b and 10d (corner portions where the wall surface 10b and the wall surface 10a intersect and corner portions where the wall surface 10d and the wall surface 10a intersect) have a triangular cross section. A duct 35 'is provided. However, in this smoking room 1 ′, the upper and lower ends of the soot duct 35 ′ are both open, and the interior of the soot duct 35 ′ is vertically divided at the height position of the table 21. Inside, the upper part is partitioned on the exhaust side, and the lower part is partitioned on the air supply side. The upper side of the soot duct 35 'communicates with the exhaust chamber 31 formed behind the wall surfaces 10b and 10d, and the lower side of the soot duct 35' is connected with the air supply chamber 30 formed behind the wall surfaces 10b and 10d, respectively. Communicate. The lower end of the air supply chamber 30 and the lower end of the exhaust chamber 31 are respectively closed, and only the communication port with the soot duct 35 'serves as an air entrance / exit.

  The lower end portion of the soot duct 35 'communicates with a double floor formed below the smoking room 1'. The conditioned air sent from the air conditioner through the double floor flows into the air supply chamber 30 behind the wall surfaces 10b and 10d from the lower side of the soot duct 35 'and smokes from the air supply port 25 below the wall surfaces 10b and 10d. Each is blown into chamber 1 '.

  An exhaust duct (not shown) is connected to the upper end of the saddle duct 35 '. Air contaminated with cigarette smoke in the smoking room 1 ′ is sucked into the exhaust chamber 31 from almost the entire surface of the wall surfaces 10b and 10d above the table 21, and exhausted from above the soot duct 35 ′ to the exhaust duct. It is like that.

  In this smoking room 1 ′, a hanging wall 45 as a shield is disposed for each of the wall surfaces 10 b and 10 d, and similarly, an open space 46 is provided between the hanging wall 45 and the ceiling 11 of the smoking room 1. . Even in the smoking room 1 ′, smoke does not stay in the central zone of the smoking room 1 ′ due to the presence of the hanging wall 45 provided at a position higher than the smoker's head and the open space 46 on the upper part. That is, the slit-shaped supply air merges in the central zone of the smoking room 1 ′ and is reversed toward the exhaust ports 26 on both sides. Part of the smoke floats near the ceiling 11 of the smoking room 1 due to buoyancy, but once blocked inside the hanging wall 45 on both sides, the free space above and below the weir (hanging wall 45) (open space 46 and It rapidly flows in the space near the lower surface of the drooping wall 45 and is sucked by the punching metals 27 on both wall surfaces 10b and 10d facing each other. In this embodiment, the area is larger in the depth direction than in FIG. 1, but the ratio of the occupant to the area can be increased. Further, in the embodiment of FIG. 2, the door 15 is disposed on the wall surface 10 a, and an undercut 50 is provided below the door 15, so that an amount of air exhausted beyond the air supply amount is led from here to the room.

  Also in this smoking room 1 ′, the air supplied toward the inside of the smoking room 1 ′ is reversed in the direction toward the wall surface 10b and sucked into the exhaust port 26, as in the smoking room 1 described above with reference to FIG. The inside of the smoking room 1 can be ventilated with a small number of ventilations. Further, in the smoking room 1 ', the smoker and his / her clothes are exposed to a one-way flow of smoke to minimize the influence of smoke, and there is almost no leakage of smoke outside the room. In addition, according to the smoking room 1 ′, air supply to the air supply chamber 30 and air exhaust from the exhaust chamber 31 are performed only from the soot duct 35 ′. Therefore, the upper and lower surfaces of the air supply chamber 30 and the exhaust chamber 31 are blocked. Therefore, the work of penetrating part processing and duct connection is easy.

  The present invention is not limited to the embodiment described above, and can be used with appropriate modifications. For example, in the smoking room 1 of FIG. 1, a soot duct 35 may be provided upright at both ends of the wall surface 10 b so that a square exhaust chamber 31 is surrounded between the two soot ducts 35. Moreover, when producing a smoking room in existing facilities, you may branch out from the existing air supply duct. If the smoking room is installed near the outer wall, the exhaust may be exhausted from a ventilation fan or the like, or it may be exhausted by combining it with an exhaust duct such as a toilet duct laid nearby (also used as an exhaust fan) Good.

  However, in the present invention, the saddle duct is not necessarily a requirement, and the upper and lower ends of the wide air supply chamber 30 and the exhaust chamber 31 partitioned at the height of the table are fully opened, and air is supplied and exhausted from the entire surface. May be. In particular, it is suitable for a facility (underfloor chamber method, ceiling chamber method) in which a double floor and a space behind the ceiling formed by a ceiling plate and a ceiling slab serve as an air flow path.

  When supplying air, if the air conditioner can apply pressure that allows intake air from the underfloor double floor, only the fan of the air conditioner may be used. If insufficient, an auxiliary fan is provided under the floor or at the air inlet of the air supply chamber 30. Also good. As a modification, the triangular culvert duct itself spreading on the door side is also punched in the upper inner wall surface and slits are formed in the lower inner wall surface. The wind speed is faster than the depth direction (the front side of the page) due to the short distance from the air outlet, and is less susceptible to door opening / closing interference.

  When applied to a floor blowing type air conditioning system, it is desirable not to provide a floor blowing outlet in the smoking room so as not to interfere with the blowing air flow from the air supply opening 25 arranged in the vicinity of the floor 12. When an existing floor is refurbished, if the existing floor outlet is arranged in the smoking room, if the opening is closed with a blind plate or the like, the air flow over the floor will not be disturbed.

  Although a plurality of slits are illustrated as the air supply port 25, one slit continuous in the depth direction or a register with a shutter can be used. In the latter case, the wind direction can be well adjusted by positioning the shutter horizontally when supplying cool air in summer or the like, and downward when supplying warm air in winter or the like.

  Although the exhaust port 26 has shown an example in which a large number of circular holes are perforated, it may have a long hole shape, an elliptical shape, a ginkgo shape, or a rhombus shape. Further, the same effect can be obtained even if one surface is formed of a breathable material such as cloth and has an appropriate resistance such as gradually reducing the exhaust flow path downward.

  In addition, the wall member in which the air supply port 25 and the exhaust port 26, the internal blower, and the table 21 are integrally manufactured can be installed at a predetermined position and provided as a smoking room if an air circulation opening is provided in the ceiling or floor. It is possible to demonstrate the effects of ease of construction and quickness that it can be configured.

  It is not always necessary to use conditioned air from the air conditioner for air supply, and external air may be taken in and purified by a filter provided in the communication path to the air supply port 25 to be supplied. The smoking rooms 1, 1 'are often provided at the corners of the installation floor. In such a case, if air is communicated from the vent caps provided on the outer wall, the duct cost can be reduced. In this case, an electric heater can be provided in the communication path as a countermeasure against cold in winter.

  Further, one of the air supply chamber and the exhaust chamber may not be connected to the main duct. For example, if the ceiling is configured as a conditioned air or exhaust passage, the ceiling can be indirectly supplied and exhausted from the ceiling chamber using the power of an air conditioner fan or an exhaust fan.

  The table 21 may be built integrally with the wall surfaces 10b and 10d, or may be installed adjacent to the wall surfaces 10b and 10d as a separate table with legs. Further, if a photocatalyst is applied to the wall surfaces 10a, 10b, 10c, and 10d, the ceiling 11, the floor surface 12, and the hanging wall 45 so that ultraviolet rays can be appropriately irradiated, it becomes a countermeasure against dirt and the frequency of cleaning can be reduced.

In the smoking room 1 described with reference to FIG. 1, in the embodiment, in the smoking room 1 having a dimension of 2.9 m × 2 m × 2.5 m (height) and a chamber volume of 14.3 m ³ , the ventilation frequency is 20 times / h, exhaust The air volume was 290 m ³ / h, and the supply air volume was 250 m ³ / h (wind speed 3.93 m / s). The air supply port 25 formed below the wall surface 10b has a slit shape of 700 mm × 50 mm arranged in two places, and the wind speed is 1.00 m / s. Further, the exhaust port 26 formed above the wall surface 10b uses a punching metal 27 having an opening ratio of 562 mm × 338 mm × 4 sheets + 588 mm × 338 mm × 4 sheets with an opening ratio of 10% (effective opening area 0.155 m ² ). The lower stage was configured using a punching metal 27 of 562 mm × 337 mm × 4 sheets + 588 mm × 337 mm × 4 sheets with an aperture ratio of 20% (effective opening area 0.310 m ² ). The average wind speed at the exhaust port 26 is 0.18 m / s.

  When the hanging wall 45 is directly attached to the ceiling 11 of the smoking room 1 and the open space 46 is formed, it occurs from the vicinity of the ashtray 20 on the table 21 as shown in FIGS. It was confirmed that a part of the smoke that had flowed into the back side of the drooping wall 45 (the side far from the wall surface 10 b) and the smoke stayed in the upper part of the smoking room 1.

  On the other hand, when the hanging wall 45 is attached to the ceiling 11 of the smoking room 1 with a gap and the open space 46 is provided, as shown in FIGS. 3C and 3D and FIG. A part of the smoke generated from the vicinity of the ashtray 20 on the wall 21 flows into the back side (the side far from the wall surface 10b) of the drooping wall 45, but the smoke flows toward the wall surface 10b through the open space 46 and is exhausted outside the room. It was confirmed that

  Further, when the hanging wall 45 is not provided on the ceiling 11 of the smoking room 1, as shown in FIGS. 3 (e), (f) and FIG. 6, a part of the smoke generated from the vicinity of the ashtray 20 on the table 21 Was swirled in the room, and it was confirmed that smoke mixed in the entire upper part of the room.
