Description

  The present invention relates to a smoke booth configured to surround cigarette smoke so that it does not flow around.

  In recent years, places where people smoke are limited, not to mention trains and airplanes, but also in offices and stations. However, cigarette smoke spreads to the surroundings even in places where smoking is restricted in offices, etc., and it causes inconvenience and disgusting people who pass nearby. Therefore, in recent years, what is called a smoking booth has been partially used.

The “smoke booth” according to Japanese Patent Application Laid-Open No. 2000-218115 is capable of preventing the leakage of contaminated air to the outside and purifying the contaminated air into clean air, and has a box-shaped wall portion and an outer wall portion. A top plate portion provided on the top of the wall, and the wall portion sucks contaminated air from a first air inlet provided in the opening of the front plate formed at a predetermined height, and purifies the contaminated air. A dust collector for exhausting clean air from a first exhaust port provided at a lower portion of the front plate,
A blower that is provided independently of the dust collector, sucks contaminated air from a second air inlet provided in the opening of the front plate, and exhausts the contaminated air from a second air outlet provided on the upper surface. With the device,
The top plate portion is provided so as to protrude forward from the upper end of the back plate of the wall portion so that contaminated air exhausted from the second exhaust port flows along the lower surface, and has a shape that hangs downward at the tip. An airflow control unit is installed.

  A “smoke booth” according to Japanese Patent Application Laid-Open No. 2003-74199 is a smoke booth that can be physically and mentally relaxed. This is a smoke booth equipped with an air purifier that cleans the air, and uses a photosynthetic plant as a smoke separation means.

However, since these conventional smoke booths are not completely separated from the surroundings, cigarette smoke diffuses to any extent. That is, these smoke smoking booths merely provide a space for smoking in a predetermined place, and do not constitute a sealed space.
"Smoke booth" according to JP 2000-218115 "Smoke booth" according to Japanese Patent Application Laid-Open No. 2003-74199

  Thus, the conventional smoke booth has the above problems. The problems to be solved by the present invention are these problems and provide a smoke booth that is completely sealed so that tobacco smoke does not diffuse to the surroundings.

  The smoke booth according to the present invention constitutes a sealed space partitioned by a partition panel, and a glass panel is used for the side wall. A ventilation fan is attached to the upper end of the ceiling or the side wall panel, and a louver serving as an air inlet is provided at the lower end of the side wall panel. A smoke eliminator is installed in the booth, and cigarette smoke is sucked into the smoke evacuator and does not fill the booth.

  A switch for operating the ventilation fan is provided in the booth. A sliding door is installed at the entrance of the booth, and the sliding door can be opened and closed semi-automatically. Further, most of the side wall surface is a glass panel, but the metal surface is coated with a special paint for preventing contamination.

  Since the smoke booth of the present invention forms a completely sealed space with the outside, the smoke of cigarettes does not diffuse outside the booth, and it does not disturb the people around. A smoke separator is installed in the smoke booth, and the smoke is sucked into the smoke separator without filling the booth. Smoke that is not sucked into the smoke separator is sucked into the ventilation fan, so it is unlikely that smoke from other people will be sucked into the booth.

  And since the louver is attached to the lower end part of a side wall panel, external air can be taken in in a booth. In addition, because the door is equipped with a semi-automatic sliding door, it can be pushed and opened by hand to enter the booth and close automatically. At that time, the air is not disturbed, and the smoke in the booth does not flow out together with the air. On the other hand, since the metal surface of the side panel is coated with antifouling paint, it can be easily wiped off with dirt and smoke attached thereto.

  FIG. 1 is an embodiment showing a smoke booth according to the present invention. The smoke booth is installed facing the wall 1 of the room, and the three side walls 2a, 2b, 2c are constituted by glass panels 3, 3,. Moreover, the sliding door 4 is attached to the side wall 2b, and galleys 5 and 5 are attached to the lower ends of the glass panels 3 and 3 of the same side wall 2b. The side walls 2a, 2b, 2c extend to the ceiling of the room, and a ventilation fan 6 is attached to the ceiling.

  Since the side walls 2a, 2b, and 2c are configured by the glass panels 3, 3,... A smoke separator 7 is installed in the center of the booth, and tobacco smoke is sucked into the smoke separator 7 so as not to fill the booth. The smoke that has not been sucked into the smoke separator 7 is sucked by the ventilation fan 6. Since the above-mentioned louvers 5 and 5 are provided at the lower end of the side wall 2b, the air that has passed through the louvers 5 and 5 is sucked into the ventilation fan 6, so that an air flow is generated in the booth. The cigarette smoke never fills up.

  The sliding door 4 is mounted at the entrance and exit of the smoke booth of the present invention. A suspension wheel is attached to the upper end of the sliding door 4 and can be opened and closed by being suspended by an upper rail provided on the ceiling of the entrance / exit. The sliding door 4 is a semi-automatic opening / closing type, and does not disturb the air during the opening / closing operation so that the air in the booth does not flow outside. That is, when the sliding door 4 is opened, the ventilation fan 6 attached to the ceiling creates an air flow from the outside into the booth. In addition, when the sliding door 4 is closed, air flows in from the galleys 5 and 5, and in any case, the air does not flow out of the booth.

  The smoke distributor installed in the center of the booth can suck tobacco smoke, but if the ventilation fan 6 does not operate, the concentration of carbon monoxide mixed in tobacco smoke cannot be reduced. That is, it is clear from the test results that dust mixed with cigarette smoke is sucked in by a smoke separator, but carbon monoxide fills the booth. Conversely, when only a ventilation fan is installed without installing a smoke separator, the concentration of carbon monoxide can be suppressed, but the dust of tobacco cannot be removed.

Therefore, the smoke booth of the present invention is equipped with both a smoke evacuator and a ventilating fan, and a sliding door is attached to the entrance / exit instead of an open / close door. Therefore, in the smoke booth
(1) An air flow of 0.2 m / S or more can be brought from an external non-smoking place to a booth that is a smoking place.
(2) In the booth, the time average suspended dust concentration can be kept at 0.15 mg / m ³ or less.
(3) In the booth, the carbon monoxide concentration is kept at 10 ppm or less.

  On the other hand, since most of the side wall portions 2a, 2b, 2c of the smoke booth shown in FIG. 1 are glass surfaces, it can be seen at a glance that it is a smoking place from the outside. 8 are provided, and metal bars 9, 9 are provided. The metal panels 8, 8,... And the metal bars 9, 9,... Are coated with antifouling paint to prevent the infiltration of cigarette dust and to easily wipe off the adhered dust.

  FIG. 2 is an enlarged cross-sectional view when the antifouling paint is applied to the surface of the metal panel 8 to form the antifouling paint layer 10. It has a structure in which inorganic components shown by black paint that retains water and oil repellency functions are arranged on the surface. It is made up. Conversely, the interior of the paint is mainly composed of organic components with excellent flexibility, and has excellent adhesion to the metal surface.

The example of the smoke booth which concerns on this invention. Antifouling paint layer painted on metal panel surface.
