Incidentally, the partition plate 1 ₁ blind ₆₁ at the upper end three, partition plates 1 ₂ blinds 6 ₂ at the upper end four, partition plates 1 ₃ blind 6 ₃ at the upper end 3, is disposed. These blinds 6 _{1 to} 6 ₃ are composed of a plurality of (for example, five) slats 7 that can be tilted and opened and closed. These slats 7 are made of a metal thin plate such as aluminum or a metal thin plate whose surface is coated with a paint or the like.

The automatic hoisting machine 8 is installed on the back of the ceiling 3 corresponding to each of the blinds 6 _{1 to} 6 ₃ , and winds and unwinds the lifting string 9 wound around each slat 7. The inclination angle of each slat 7 is adjusted by the lifting string 9. Each of the slats 7 is inclined upward toward the smoking room 4 with respect to the horizontal direction as shown in FIGS. 2 and 3 during operation of the air cleaner described later, and the inclination angle (ε) is 0 °. <Ε <90 °, more preferably 30 ° ≦ ε ≦ 60 °.

At least one, for example three ceiling suspension type air cleaner 10 ₁ to 10 _3, so as to be located in the vicinity of the partition plate 1 ₁ to 1 ₃ to the ceiling 3 of the smoking chamber 6 as shown in FIG. 1 is set up. That is, the first air cleaner 10 ₁ has a corner portion where the partition plate 1 ₁ with the door and the partition plate 1 ₂ intersect, and the second air cleaner 10 ₂ has the partition plate 1 ₂ and the partition plate 1 ₃ intersect. corner, third car air cleaner ₁₀₃ is disposed at the corner portion of the partition plate 1 ₃ and the wall 2 intersect.

The ceiling-suspended air cleaners 10 ₁ to 10 ₃ (for example, 10 ₁ ) have an inverted square frustum shape attached to the ceiling 3 of the smoking room 4 via a top plate 11 as shown in FIGS. The housing 12 is provided. The housing 12 has a suction grill 13 at the bottom and is surrounded by four housing side plates 14. A plurality of rectifying plates 15 are respectively disposed on the two housing side plates 14 facing each other.

  The dielectric filter 16 is disposed in the vicinity of the lower portion in the housing 12 so as to face the suction grill 13 with a desired distance. The dielectric filter 16 is inserted into and removed from the casing 12 through an opening / closing window (not shown) of the casing side plate 14 for the purpose of replacement or the like. The dielectric filter is attached to the lower frame 17 made of an insulating material having a metal mesh portion (not shown) divided and supported, for example, and to be opened and closed by a hinge mechanism (not shown). For example, an upper frame 18 made of an insulating material having a metal mesh portion (not shown) divided and supported in four is provided. The electronic filter element 19 is accommodated in the frames 17 and 18. The electronic filter element 19 has a structure in which non-woven fabric layers 21a and 21b made of synthetic resin are stacked on top and bottom with a conductive layer (for example, a mesh plate carrying activated carbon) 20 interposed therebetween. A discharge needle (not shown) to which a positive potential is applied is inserted into the upper nonwoven fabric layer 21a of this element 19 and the activated carbon carrying mesh plate 20. The metal mesh portions of the frame bodies 17 and 18 are at ground potential.

A rotating blower, for example, a sirocco fan 22 is attached to the top plate 11 in the housing 12.

Next, the operation of the smoking room structure according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3 and 4 described above. FIG. 4 is a cross-sectional view showing a flow state of the smoking airflow near the blind (for example, 6 ₂ ). In order to simplify the description, the operation will be described by taking the ceiling-suspended air purifier 10 ₁ as an example among the _three ceiling-suspended air purifiers 10 ₁ to 10 ₃ .

Activate each automatic winding machine 9, of the partition plate ₁ 1 to 1 ₃ the upper part of the blind ₆₁ through ₃ by Tsuuehimo 9, opposite the three ceiling suspension type air cleaner 10 ₁ to 10 ₃ Close the blinds at the other locations by opening the blinds at the locations semi-open. In the half-opened blinds 6 _{1 to} 6 ₃ , each slat 7 is inclined upward by about 40 ° toward the smoking room 4 with respect to the horizontal direction as shown in FIGS.

In this state, the sirocco fan 22 in the housing 12 in the _three ceiling-suspended air purifiers 10 ₁ to 10 ₃ is rotated, for example, counterclockwise. In this case, smoke stream of a smoking chamber 4 is sucked into housing 12 through the suction grill 13 of the casing 12 in the Ceiling type air purifier 10 _1, it passes through the dielectric filter 16. When the smoking airflow passes through the dielectric filter 16, a positive voltage, for example, a DC voltage of several thousand volts, is applied to a discharge needle (not shown) of the dielectric filter 16 to ground metal mesh parts (not shown) of the upper and lower frames 18 and 17. 2) to generate positive ions, thereby causing dielectric polarization between the activated carbon-carrying mesh plate 20 of the electronic filter element 19 into which the discharge needle is inserted and the metal mesh portion, and the smoking air flow The particulate dust inside is adsorbed and removed by the electronic filter element 19.

The air flow (dust-free air flow) from which dust has been removed by passing through the dielectric filter 16 rises in the housing 12 (airflow rotation space) above the dielectric filter 16 by the rotation of the sirocco fan 22, The air is blown into the room from the left and right rectifying plates 15. At this time, each slat 7 of the blind 6 ₂ facing to the left side of the current plate 15 is in a semi-open state in which upward approximately 40 ° inclined to the smoking chamber 4 side with respect to the horizontal direction as shown in FIG. 2 Therefore, dust-free air flow blown out from the rectifying plate 15, i.e. the clean air stream flows to the office (outside) through the gap between the slats 7 of the blind 6 _2.

On the other hand, the clean air adjusted to an appropriate temperature in the office room due to the pressure difference between the room and the outside due to the outflow of air in the smoking room 4 (indoor) is the blind as shown in FIGS. 6 the gap between the _two slat 7 and the blind 6 ₂ are similarly inclined, it flows into the indoor respectively through the blind ₆₁ of the slat 7 is a semi-open state. Inflow clean air is drawn along with smoking airflow suction grill 13 of the casing 12 in the Ceiling type air cleaner 10 ₁ as shown in FIGS. 2 and 3, the removal of the same dust to that described above, clean Is made.

Further, the smoking airflow immediately after smoking generated in the smoking room 4 is relatively high in temperature and rises because it is lighter than the surrounding air. The flow state in the vicinity of such a smoking airflow blind (for example, 6 ₂ ) will be described with reference to FIG. Relatively higher temperature smoke stream immediately after smoking, rises along to adhere to slat 7 of the blind 6 ₂ as indicated by an arrow, is cooled in the vicinity of the ceiling 3 of the smoking chamber 4.

  That is, the smoking airflow generally contains a lipophilic component, while the slat 7 is also generally made of a metal sheet or a paint-coated sheet and has lipophilicity. Further, as described above, the slat 7 is inclined upward by, for example, about 40 ° toward the smoking room 4 with respect to the horizontal direction. As a result, the smoking airflow rises so as to adhere to the inclined slat 7 while receiving an affinity, so that it reaches the vicinity of the ceiling 3 of the smoking room 4 and is cooled without leaking outside.

As described above, according to the first embodiment of the present invention, the smoking airflow generated in the room (smoking room) 4 is cleaned by, for example, the three ceiling-type air purifiers 10 ₁ to 10 ₃ and cleaned. from smoking chamber to flow out to the outdoor (office) through the gap of the slat 7 of the blind ₆₁ through _3, the clean air which is adjusted to an appropriate temperature by the outdoor air-conditioning through the gap of the slat 7 of the blind ₆₁ through ₃ The air flows into the room and air circulation between the room and the outside can be realized. That is, the blinds 6 _{1 to} 6 ₃ function as air supply / exhaust members for outdoor air. Therefore, when cleaning the smoking air flow in the room, installation of the air supply / exhaust device including the duct in the room can be omitted, and the air conditioning equipment can be made smaller, thereby reducing the running cost and the equipment cost. Smoking room structure can be provided.
