Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smoke separating booth having an air purifying function for purifying air contaminated mainly by cigarette smoke into clean air.

[0002]

2. Description of the Related Art In recent years, various indoor facilities such as stations, airports, hospitals, offices, and the like have been promoting smoking separation as a measure against smoking. This separation is generally achieved by specifying smoking areas in certain areas to protect non-smokers from tobacco smoke. In view of such circumstances, various smoking booths have been developed for partitioning a certain space in an indoor facility from other spaces to form small compartments as smoking areas. Many of these smoking booths are provided with an air purifying function for purifying air contaminated by tobacco smoke into clean air, and such an air purifying function is generally performed by the following means. . That is, the fan of the dust collection device provided in the booth is driven to suck air contaminated by the smoke of the tobacco in the booth from the intake port, and the sucked contaminated air catches the smoke of the cigarette and its odor. The air is purified into clean air by passing through a dust collection filter of the dust collection device, and exhausted from an exhaust port.

[0003]

As described above, a conventional smoke separating booth uses a dust collecting device to purify contaminated air into clean air, but this dust collecting device collects the contaminated air. Because it is a mechanism that purifies the air into clean air by passing it through the dust collection filter of the dust collector, the suction power of the fan of the dust collector normally sucks all the contaminated air generated in the booth into the dust collector. It is difficult to do.
For this reason, some contaminated air that is not sucked into the dust collection device stagnates in the booth, and the stagnant contaminated air leaks out of the booth to cause discomfort to non-smokers. .

Accordingly, the present invention circulates air contaminated by tobacco smoke in a booth without stagnation in the booth, thereby preventing leakage of the contaminated air to the outside and purifying the contaminated air. It is an object to provide a smoke separation booth that can be purified into air.

In addition, by providing the airflow direction adjustment unit 32 as described above, the flow speed of the remaining contaminated air P ′ is reduced as compared with the case where the airflow direction adjustment unit 32 is not provided. Therefore, the remaining contaminated air P ′ flows in a certain direction while spreading in the width direction of the airflow control unit 31. As a result, the remaining contaminated air P ′ flows to the first and second air inlets 41 and 51 while catching the contaminated air P generated in the smoke separating booth 1 in a wide area so as to be pushed out from behind, and the smoke separating booth 1 can promote the air cleaning action. Also,
The residual contaminated air P ′ whose flow direction has changed by colliding with the airflow control unit 31 may entrain surrounding air and form a vortex, but by providing the airflow direction adjustment unit 32,
As described above, since the direction of the airflow is adjusted to a certain direction and the speed of the airflow is also reduced, the generation of vortices can be prevented, and the air stagnating in the smoke separating booth 1 can be eliminated.
