BEST MODE FOR CARRYING OUT THE INVENTION The present invention has a ceiling fan provided so as to blow air in the ceiling direction, and a shield plate vertically provided on the ceiling so as to surround the ceiling fan, and the ceiling fan and the shield are provided. A plurality of air cleaners are arranged radially between the plates.By operating the ceiling fan, the airflow in the smoke separation space spreads from the floor to the ceiling, spreads along the ceiling surface, and then drops to the ceiling surface. The shielding plate provided deflects the wind direction of the airflow toward the floor and forms a circulating airflow that joins the rising airflow from the floor to the ceiling again. The smoke of cigarettes smoked in this circulating airflow is the ceiling fan. Since it is cleaned by an air cleaner installed between the shielding plate and the shielding plate, the air curtain effect is enhanced, and the air in the smoking space can be purified without the cigarette smoke leaking out of the smoking space.

Further, between the suction side ends of the air purifier, a partition plate is hung from the ceiling surface so as to surround the ceiling fan, and has a partition plate having substantially the same height as the height of the air purifier body. The cigarette smoke that is raised toward the ceiling by the ceiling fan spreads around the ceiling surface, but the partition plate prevents the smoke from spreading outside the suction port of the air purifier. As a result, the smoke of the cigarette can be guided to the suction port of the air purifier with almost no leakage.

Further, a polygonal cone-shaped ceiling fan rectifying frame that covers the ceiling mounting portion or the main body of the ceiling fan is detachably provided on the ceiling surface, and the outer diameter dimension of the ceiling installation surface of this rectifying frame is outside the blades of the ceiling fan. The circular airflow due to the operation of the ceiling fan is deflected while being rectified from the ceiling direction toward the shield plate without directly colliding with the ceiling surface by the polygonal cone-shaped ceiling fan rectification frame. So
This has the effect of preventing the accumulation of cigarette smoke near the ceiling surface and reducing the amount of dirt on the ceiling surface to which the ceiling fan is attached.

In addition, a smoke sensor for detecting cigarette smoke is arranged on the ceiling surface above the ceiling fan, and the cigarette smoke in the ascending air current formed by the ceiling fan can be directly detected by the smoke sensor. Therefore, there is an effect that the dirt of the air can be surely detected and the stable operation of the air cleaner can be performed even during the operation of the air cleaner.

Further, a human sensor for detecting the presence of a person in the smoking space is provided, and if a person is present in the smoking space, the ceiling fan is driven to remove the air from the smoking space. Since the operation of the ceiling fan is stopped after the cleaning of the air conditioner, there is an effect that an optimum automatic operation of the device in consideration of energy saving can be performed.

Further, each air purifier is provided with a dirt sensor capable of detecting the smoke of cigarettes, and the dirt sensor built into each air purifier is used to detect the dirt level of the air. Since the air purifier determines the air volume, it has an effect that the air cleaner can be automatically operated with an appropriate air volume.

The ceiling fan is also provided with a total air volume calculating means for calculating the total air volume of the operating air volumes of the plurality of air purifiers, and an air volume control means for operating the ceiling fan with an air volume substantially equal to the total air volume. Since the air flow rate of the circulating air flow formed by the above does not exceed the processing air flow rate of the plurality of air purifiers, it has an effect of being able to form an optimum air flow rate circulating air flow in the smoking space.

Further, the shield plate hung from the ceiling surface is provided with a rectifying element provided at the joint portion of the ceiling,
Since the airflow in the ceiling near the shield plate is smoothly deflected downward, it has the effect of suppressing turbulence of the airflow and enhancing the air curtain effect.

In addition, the shield plate hung from the ceiling surface allows the air flow blown out from the air cleaner to extend in the long side direction of the shield plate.
The airflow control means for uniformly guiding the airflow distribution is provided, and the airflow blown out from the air cleaner is guided by the airflow control means so that the airflow distribution becomes uniform in the long side direction under the shielding plate. This has the effect of making the air flow distribution of the air curtain uniform and enhancing the shielding effect.

Further, a partition is provided in the same enclosure shape as that of the ceiling fan surrounding the ceiling fan, and the partition is provided outside the portion just below the shield, and since the partition blocks the influence of disturbance on the smoke-separating space, air conditioning etc. It has the effect of suppressing the diffusion of cigarette smoke due to the external disturbance.

Further, the partition is provided with a radiant heating means, and the radiant heating means can heat the inside of the smoke-separating space inside the partition by a radiative effect. It has the effect that it can be suppressed.
