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).

  In recent years, due to the enforcement of the Health Promotion Act, public facilities have allowed smoking only in limited spaces. Recently, not only inside buildings but also outdoors, smoking is prohibited in certain areas, and smoking may be allowed only in partitioned smoking rooms. In smoking rooms where smoking is allowed, it is important that cigarette smoke does not leak around the smoking room at the height of the person. Furthermore, it is desirable that cigarette smoke does not adhere to clothes even in a smoking room, and that smoke does not inhale more than the smoker needs by filling the smoking room with smoke.

  According to the results of the applicant's prior art search, (1) the air blower provided near the ashtray generates an upward air flow and exhausts it from the opposite exhaust port (Patent Document 1), (2) the 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 an upward airflow are installed on the table (Patent Document 2) and (3) Finding what uses a blower top suction air purifier and diverts the ratio of supply air volume and exhaust air volume of the lower blowout to 1: 4 (suction volume is 5 times the blowout volume) (Patent Document 3) It was done.

  However, in the above-described inventions (1) to (3), the smoker feels a draft. Also, because the equipment is installed indoors, it cannot meet the demand for space saving. In addition, costs such as a mini blower and an air purifier are required. Also, it is not easy to install outdoors, and there is a problem that it takes time to remove it when it is no longer needed.

  An object of the present invention is to provide a smoking room that can be easily installed outdoors and easily removed in addition to solving the above-described problems.

According to the present invention, there is provided a smoking room which is installed outdoors and is partitioned by four wall surfaces, and a table for placing an ashtray on one wall surface is provided, and outside air is taken into the one wall surface below the table. A rainproof device is provided on the outside of the intake port, and an exhaust port is formed on the one wall surface above the table. The corrosion-resistant material is spaced above the table and spaced from the one wall surface. An exhaust chamber is provided between the one wall surface and the outer wall above the table, and an exhaust fan for exhausting the air in the exhaust chamber to the outside is provided. A smoking room is provided.

  The exhaust fan may be provided above the ceiling surface. Further, at least two of the four wall surfaces may be connected to each other so as to be foldable, and the table may be foldable with respect to the one wall surface.

  According to the present invention, it is possible to easily provide a space-saving smoking room in which a smoker's amenities are secured. This smoking room can be easily installed outdoors and removed easily.

  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. 1 and 2 are a front view and a plan view for explaining the configuration of the smoking room 1 according to the embodiment of the present invention. FIG. 3 shows a front view of the wall surface 10b on which the table 20, the air supply port 25, and the exhaust port 26 are provided.

  The smoking room 1 is surrounded by four wall surfaces 10a, 10b, 10c, and 10d, and the upper and lower sides are surrounded by a ceiling surface 11 and a floor surface 12 (the upper surface of the base 12 '), so that the smoking room 1 is partitioned for smoking. It is formed in a rectangular parallelepiped space.

  In the illustrated smoking room 1, a door 15 is provided on one wall surface 10a. A smoker can enter and leave the smoking room 1 by opening and closing the door 15. When the door 15 is closed, air does not leak from the inside of the smoking room 1 to the surroundings at the living height of the person.

  A table 20 is provided on the inner side surface of one wall surface 10b orthogonal to the wall surface 10a on which the door 15 is provided. The table 20 is provided in the vicinity of the waist of the smoker who has entered the smoking room 1 with a depth of, for example, about 400 mm and the full width of the wall surface 10b in the indoor direction. In this embodiment, the height of the table 20 is set to 900 mm above the floor with respect to the smoking room 1 having a height of 2500 mm. An ashtray can be placed on the table 20. The ashtray may be fixedly arranged on the table 20. The wall surface 10b is provided with an outside air inlet 25 for opening outside air into the inside of the smoking room 1 from the outside below the table 20 so as to open below the wall surface 10b. An exhaust port 26 for sucking and exhausting air is provided. As will be described later, when the smoking room 1 is installed outdoors, it is desirable to attach a rainproof device such as eaves (not shown) to the outside of the intake 25.

  The wall surface 10c facing the wall surface 10a provided with the door 15 and the other wall surface 10d orthogonal to the wall surface 10a provided with the door 15 (the other wall surface 10d facing the one wall surface 10b) and the floor surface 12 are , Both are substantially closed surfaces that do not allow air to flow from the inside of the smoking room 1 to the outside. The wall surfaces 10c and 10d may be glass surfaces, for example.

  Below the table 20, the wall surface 10b is composed of, for example, a single panel without air permeability. The air supply port 25 disposed below the table 20 has a slit shape that is long in the width direction at the bottom 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 20, exhaust walls 26 made up of a number of circular holes are generally distributed and formed on the wall surface 10 b. Above the table 20, the wall surface 10b has a large number of exhaust ports 26 opened on the inner wall surface. For the convenience of processing, in the illustrated embodiment, the inner wall surface of the wall surface 10b above the table 20 is constituted by a punching metal 28 having a plurality of exhaust ports 26 opened at equal intervals substantially in the width direction. An outer wall made of a corrosion-resistant material such as stainless steel is erected at a distance from the wall surface 10b (punching metal 28) above the table 20. The outer wall is flush with the outer wall surface below the height of the table 20 of the wall surface 10b when viewed from the outside.

  As described above, the space formed in the partition having the same width as the wall surface 10 b and formed by the wall surface 10 b (punching metal 28) and the outer wall above the table 20 is defined as the exhaust chamber 31.

  The lower surface of the exhaust chamber 31 is closed by the upper surface of the table 20. On the other hand, the upper surface of the exhaust chamber 31 communicates with a ceiling space 32 formed above the smoking room 1. The left and right sides of the exhaust chamber 31 are respectively closed by a wall surface 10a on which the door 15 is provided and a wall surface 10c facing the wall surface 10a.

  An exhaust fan 33 is provided in the ceiling space 32. Due to the operation of the exhaust fan 33, the air contaminated with cigarette smoke in the smoking room 1 is sucked into the exhaust chamber 31 through the numerous exhaust ports 26 formed in the wall surface 10b above the table 20, and the ceiling. The air is exhausted from the back space 32 through the duct 34 to the outside.

  Thus, by exhausting the air contaminated with the tobacco smoke in the smoking room 1 by the operation of the exhaust fan 33, the inside of the smoking room 1 is decompressed and disposed below the table 20 on the wall surface 10b. Outside air is sucked into the inside of the smoking room 1 from the air supply port 25. In this case, it is preferable to adjust the amount of exhaust by the exhaust fan 33 so that the wind speed of the air supplied from the air supply port 25 is 0.3 to 0.7 m / sec. For this purpose, the exhaust air velocity from the exhaust port 26 is, for example, sucked at 0.1 to 0.3 m / sec (average 0.2 m / sec in the present embodiment). In addition, by supplying the air from the air supply port 25 by operating the exhaust fan 33, the inside of the smoking room 1 is always kept at a negative pressure, and the leakage of contaminated air to the outside at the level of a person's living area is avoided. .

  In the smoking room 1 configured as described above, air contaminated with cigarette smoke in the smoking room 1 enters the exhaust chamber 31 from the numerous exhaust ports 26 distributed over the entire wall surface 10b above the table 20. By sucking in and exhausting outside through the ceiling space 32 through the duct 34, it is possible to realize a smoking space that secures the amenity of the smoker. Moreover, the air sucked into the smoking room 1 from the air supply port 25 by setting the wind speed of the air supplied from the air supply port 25 below the table 20 to a low speed of 0.3 to 0.7 m / sec. However, it reverses in the direction toward the wall surface 10b and forms a reverse flow sucked into the exhaust port 26, so that the inside of the smoking room 1 can be ventilated with a small number of ventilations. For example, in a system provided with 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, since the air is circulated at a low speed and with a small air volume, the thickness of the exhaust chamber 31 can be extremely reduced in combination with the use of the full width of the wall 1b.

  Further, smoke smoked in the vicinity of the upper surface of the table 20 is quickly discharged from the exhaust ports 26 arranged on the wall surface 10b above the table 20. Thus, the air sucked into the exhaust chamber 31 is exhausted to the outside. At that time, the table 20 has an important significance in the airflow property as an airflow separator.

  In addition, the smoking room 1 can be easily installed by being fixed to the base 12 ′, an existing concrete floor surface, or other ground even outdoors, and can be easily removed. The smoking room 1 can be used as a temporary smoking booth for temporary venues and facilities for performing exhibitions and events, in addition to public facilities and predetermined areas where smoking is prohibited. Moreover, this smoking room 1 may be installed outdoors adjacent to a bus terminal and a hospital building, and can also be applied to a smoking bus. If the smoking room 1 is installed outdoors, it will be possible to smoke without a umbrella even on rainy days, and it will be possible to separate smoke even outdoors where people gather.

  As mentioned above, although the example of preferable embodiment of this invention was shown, this invention is not limited to the form illustrated here. For example, the table 20 may be configured to be foldable as indicated by the dotted line in FIG. Further, as shown in FIG. 5, the ceiling plate constituting the ceiling surface 11 and the wall materials constituting the wall surfaces 10a, 10b, 10c, and 10d are preliminarily bonded to each other, and other detachable structures are provided. The four wall surfaces 10a, 10b, 10c, and 10d surrounding the wall may be connected to each other so as to be bendable. If the wall surfaces 4a, 10b, 10c, and 10d are connected to each other so as to be foldable in this way, the corners on the diagonal line are pushed and each wall surface 10a, 10b, The smoking room 1 can be folded by bending the portions 10c and 10d at the connecting portions, for example, by bringing the wall surfaces 10a and 10d into close contact with each other and bringing the wall surfaces 10b and 10c into close contact with each other. In this case, even if the wall surfaces 10a and 10b are brought into close contact and the wall surfaces 10c and 10d are brought into close contact, the smoking room 1 can be similarly folded. Further, when the smoking room 1 is folded as described above, the table 20 is folded downward as shown in FIG. 4 so that the table 20 does not get in the way and the smoking room 1 can be easily folded. It can be folded into a narrow flat state. In the smoking room 1, since an air supply chamber for supplying air into the smoking room 1 is not necessary, it can be made thinner when folded. The smoking room 1 folded in a flat state as described above can be mounted in piles on a loading platform such as a truck and is not bulky, so it is convenient for transportation. A hinge or other known means can be applied to the folding of the table 20 and the wall members constituting the wall surface.

  At the installation site, the wall surfaces 10a, 10b, 10c, and 10d are spread on the base 12 'so that the bending angle of each connecting portion is 90 °, and the ceiling surface 11 is further up. By placing it, the smoking room 1 can be easily installed. Further, when the bending angle of the connecting portion between the wall surfaces 10a, 10b, 10c, and 10d is expanded to 90 ° in this way, the wall surface 10a, 10b, 10c, 10d can be maintained in an expanded state, and the shape of the smoking room 1 formed in a rectangular parallelepiped can be maintained. The base 12 'and the ceiling surface 11 have a structure that can be freely attached to and detached from each of the wall surfaces 10a, 10b, 10c, and 10d (such as a structure that fits with a rugged male and female).

  Moreover, even if the smoking room 1 is once installed in this way, as described above, the table 20 is folded again downward, and the wall surfaces 10a, 10b, 10c, and 10d are folded at the connecting portions to narrow the width. There is an advantage that it can be easily removed by making it flat, and can be transported in a non-bulky state by mounting a plurality of smoking rooms 1 on a loading platform such as a truck.

  1-3, the example which has arrange | positioned the exhaust port 26 to the wall surface 10b above the table 20 was shown. However, for example, as shown in FIG. 6, an exhaust port 35 that sucks and exhausts indoor air may also be provided at a location near the wall surface 10 b of the ceiling surface 11. According to this configuration, the air supply port 25 is positioned below the height position of the ashtray placed on the table 20, and the exhaust ports 26 and 27 are positioned above the height position of the ashtray. If the exhaust port 35 is provided near the wall surface 10b of the ceiling surface 11 as described above, the smoke of the cigarette that has risen to the ceiling due to the inclusion of hot air can be sucked from the exhaust port 35 and exhausted.

  Moreover, you may provide the shield 40 in the ceiling part of the smoking room 1, as shown with the dashed-dotted line in FIG. The shield 40 is composed of a plate member disposed substantially parallel to the wall surface 10b on which the table 20 and the exhaust port 26 are provided, and air flowing toward the exhaust port 26 (wall surface 10b) above the smoking room 1. It arrange | positions so that it may partially shield. An open space 41 is provided between the shield 40 and the ceiling surface 11 of the smoking room 1. As the shield 40, for example, a steel plate having a height of 250 mm is suspended by a bolt through a metal fitting, and a gap (open space 41) having a height of 50 mm is provided between the upper end of the shield 40 and the ceiling surface 11. . The material of the shield 40 may be, for example, a vinyl curtain with a weight, a stainless steel plate, or an acrylic plate, and the open space 41 may be formed by directly attaching the upper part of the material to the ceiling surface 11. good. Note that the position of the shield 40 hangs down in the width direction substantially in the middle of the wall surface 10b on which the table 20 and the exhaust port 26 are formed and the wall surface 10d opposite to the wall surface 10d (position of 950 mm with respect to depth 1850 mm in this embodiment). Has been. 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).

  If such a shield 40 is provided on the ceiling of the smoking room 1, the air sucked from the air supply port 25 toward the smoking room 1 is reversed and exhausted in the direction toward the wall surface 10b. It will pass above and below 40. According to the knowledge of the present inventors, when the shield 40 is not installed on the ceiling portion of the smoking room 1, it has been visually confirmed that smoke vortices are generated near the indoor ceiling portion. If this stays, there is a risk of smoke adhering to the smoker's head. Therefore, the present inventors succeeded in preventing smoke vortex retention by providing a shield 40 on the ceiling of the smoking room 1. Further, it has been found that even if the occupant in the smoking room 1 moves away from the position of the ashtray, for example, exhaust is effectively performed by the reverse flow caused by suction from the exhaust port 26 and the wind around the shield 40.

  Further, such a shield 40 may be configured to be fixed to the ceiling surface 11 or the wall surfaces 10a and 10c of the smoking room 1, but for example, a roll blind can be used as the shield 40. With this configuration, it is possible to easily form a shield 40 with a gap using a commercially available product. In this case, as the open space 41, a gap between the hanging tool from the ceiling surface 11 and the roll blind can be used. Further, as the shield 40, it is possible to use illumination in which a lamp such as a fluorescent lamp is built in a case such as an acrylic plate, or illumination in which a transparent banner is attached to a lamp such as a fluorescent lamp. If the illumination is used in this way, a shielding effect can be obtained by using a necessary member (illumination) without adding a special member as the shield 40. The shield 40 may be slightly inclined, and the installation means may be supported by a stand with legs in addition to hanging from the ceiling surface 11. The height of its lower end is higher than the respiratory height when the indoor smoker stands, preferably higher than the position of the head, so that it does not interfere with movement. The lower end of the door 15 is preferably higher than the height of the door 15.

  1-3, the form which provided the table 20 in one wall surface 10b among the four wall surfaces which partition the circumference | surroundings of the smoking room 1, and provided the inlet 25 and the exhaust port 26 on the upper and lower sides was shown. However, in the present invention, the table 20 is provided on one wall surface 10b of the four wall surfaces partitioning the periphery of the smoking room 1 and the other wall surface 10d opposed thereto, and an air supply port 25 and an exhaust port 26 are provided above and below the table 20, respectively. It is good also as the provided structure. Even in such a configuration, similarly to the smoking room 1 described above with reference to FIGS. 1 to 3, the air supplied toward the inside of the smoking room 1 is reversed in the direction toward the wall surfaces 10 b and 10 d to the exhaust port 26. A reversing flow is formed, and the inside of the smoking room 1 can be ventilated with a small number of ventilation. Further, in the smoking room 1, the smoker and his / her clothes are exposed to a one-way flow of smoke, so that the influence of smoke can be minimized and almost no smoke leaks outside the room. Such a smoking room 1 is suitable for a relatively large smoking room or a smoking room with many people.

  In addition, the table 20 may be formed integrally with the wall surface 10b or the wall surface 10d, or may be installed adjacent to the wall surface 10b or the wall surface 10d as a separate table with legs. Further, if a photocatalyst is applied to the wall surfaces 10a, 10b, 10c, 10d, the ceiling 11, the floor surface 12, and the shield 45 so that ultraviolet rays can be appropriately irradiated, it becomes a countermeasure against dirt and the frequency of cleaning can be reduced.

  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 out of the room together with the fresh air by the reverse flow. In other words, it can be ventilated with a small air volume, contributing to energy saving. In addition, the air supply port 25 for sucking air from the outside into the smoking room 1 below the table 20 is formed into a slit shape that is long in the width direction at the bottom of the wall surface 10b or the wall surface 10d. The airflow can be supplied, and the supply air is blown into the room in a horizontally long shape in the width direction. Thereby, it becomes the structure by which the airflow which creeps a floor is blown out toward the opposing surface of the smoking room 1 like what is called substitution ventilation. The air supply port 25 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 smoking room 1 may be configured by modifying a telephone box that is no longer used. In this case, it can be easily manufactured by removing the telephone and forming the air supply / exhaust surface on the surface where the telephone is installed. In this way, it is possible to regenerate the telephone box that is being removed at present, and it can be suitably adapted to the era of non-smoking on the street. In this case, the telephone is removed from the existing telephone box, and the table on which the telephone has been placed is used as the table 20, and an appropriate distance from the outer wall is placed above the table 20 (the table on which the telephone has been placed). The exhaust chamber 31 can be easily formed by opening and installing a punching plate. Further, an air supply opening 25 is opened on the outer wall below the table 20 (a table on which the telephone has been placed so far), and air in the exhaust chamber 31 is provided by an exhaust fan 33 installed at an appropriate location such as on the roof of a telephone box. May be configured to be exhausted. In addition, when there exists an existing exhaust port etc. in a telephone box, it is desirable to block the thing in the location which cannot be used as the air supply port 25. FIG. For the exhaust fan power, for example, a solar cell and a battery may be used. Further, the exhaust fan may be operated when a coin is inserted.

  According to the present invention, the above-mentioned advantages can be enjoyed, and a table 20 on which an air supply / exhaust function and an ashtray are arranged is provided, and the smoking room 1 can be easily built as a prefabricated member. Can be formed. The undercut from the door 15 and other openings are eliminated, and an airtight structure is provided between the periphery of the door 15 by packing or a bite structure. Then, the air flow to the outside can be limited to only the joint between the panels. Moreover, when the circumference | surroundings of the smoking room 1 are non-air-conditioning, the thermal environment in the smoking room 1 can be ensured. For example, air-conditioned air is taken in an outpatient smoking booth, but the surrounding area may be a space for handling in-house work, etc. Also, when building the smoking room 1, use the wall and floor of the building, and if the panel uses the corner of the building, for example, if it is a floor blowout, then two (side surfaces other than the corner) Just do it. Even with the two-sided face-off type, if the glass wall of the building is used as one of the side walls, three sides are sufficient.

  The present invention responds to the demand for smoke separation in recent years, and can provide a space allowing smoking in a building together with flexibility and amenity at low cost and energy saving, and is useful as a building facility.
