Abstract

PURPOSE:To perform an efficient supplying of interior blown air within an entire room and to improve a cigar smoke collecting performance in an air cleaning system in which contaminating items such as cigar smoke generated within the room is removed and processed. CONSTITUTION:An air cleaning system is constructed such that an interior side of a ceiling 1 is provided with a groove 2. One end of the groove 2 is provided with an air blowing port 3, the other end of the groove 2 is provided with a suction port 4. The air blowing port 3 is comprised of a groove blowing port 3a for blowing air in a direction of the suction port 4 and an interior blowing port 3b for blowing air toward an interior side. The suction port 4 and the blowing port 3 are communicated by a cleaning device 7 and a duct 8. In an air cleaning system, the interior air blowing port 3b is guided from the groove end by a duct, and arranged lower is than a height of a contamination generating source.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purification system for removing and treating pollutants such as cigarette smoke generated indoors.

[0002]

2. Description of the Related Art Conventionally, in this type of air purifying device,
As shown in FIG. 3, a groove 2 is provided on the indoor side of the ceiling 1, an outlet 3 is provided at one end of the groove 2, and a suction port 4 is provided at the other end.
The blow-out port 3 is provided with a blow-out port 3a that blows out in the direction of the intake port 4 and a blow-out port 3b that blows out in the indoor direction, both of which are provided in the groove 2 and are provided in the groove 2. 3 is known as an air purification system in which a duct 8 communicates with a purifying device 7 including a blower 5, a purifying filter 6 and the like. In the figure, the arrow indicates the air flow, and the alternate long and short dash line indicates the downward spread range of the groove flow.

[0003]

In the air purifying apparatus shown in FIG. 3, the air blown on the market diffuses contaminants,
Compared to a general air purifier (diffusion method) that sucks and purifies diffused air, the cigarette smoke that rises to the upper part of the room is attracted by the airflow toward the suction port 4 along the groove 2 without stirring the room. Since it is transported to the suction port 4, it has a long collection area and has the advantage of improving purification performance.
Since the outlets 3a and 3b were close to each other in the ceiling 1,
Since the airflow blown out from the groove blowout port 3a attracts the clean air blown out from the indoor blowout port 3b (air purified by the purifying device) immediately after it is blown, the clean air is not efficiently supplied to the entire room, Since the effect of attracting the groove flow cannot be maintained over the entire groove 2, there is a problem that the cigarette smoke collecting performance deteriorates depending on the location.

The object of the present invention is to improve the above-mentioned drawbacks of the prior art, to efficiently supply indoor blown air to the entire room, and the groove flow over the entire groove 2 attracts tobacco smoke. It is an object of the present invention to provide an air purification system capable of improving the collection performance.

[0005]

In order to achieve the above object, an air purification system according to the present invention is provided with a groove 2 on the indoor side of a ceiling 1, an outlet 3 at one end of the groove 2 and an outlet 3 at the other end. The suction port 4 is provided, and the blow-out port 3 is composed of a groove blow-out port 3a that blows out in the direction of the intake port 4 and an indoor blow-out port 3b that blows out in the indoor direction. It is characterized in that it is installed below the height of the source and that the suction port 4 and the blowout port 3 are communicated with each other by the purifying device 7 and the duct 8. The above problem is solved by this configuration. Is.

The purifying device 7 is composed of a purifying filter, an electric dust collector and the like. The height of the pollution source means the mouth of the smoker, the height of the ashtray, the height of the stove, etc., and the indoor outlet 3b should be at the same position as the target position of the pollution source or below it. To do.

[0007]

[Operation] The clean air blown out from the indoor blowout port 3b is supplied near the source of pollution such as smokers, and diffuses into the entire room to clean the entire room. Cigarette smoke generated by the smoker in the air flow blown toward the suction port 4 (maintaining the main flow in the groove 2) (heat that the cigarette itself has, or if necessary, installed upward in the vicinity of the smoker) It is attracted by the blow-out auxiliary fan 11 as it rises), gradually spreads and flows along the groove 2 to the suction port 4, flows into the purification device 7 from the suction port 4, is purified, and then is supplied again into the groove 2 and the room. To be done.

The amount of air attracted is equal to the amount of air supplied into the room from the outlet 3b.

[0009]

EXAMPLES Examples of the present invention will be described below.

In the figure, the arrow indicates the flow of air, and the alternate long and short dash line indicates the downward spread range of the groove flow. 1 and 2 show an embodiment of the present invention.

The ceiling 1 is installed under the ceiling portion 12 of the building frame with a space (under-ceiling space 13) by hanging bolts.

On the ceiling 1, several grooves 2 having a U-shaped cross section having an opening 9 on the indoor side are provided in parallel from one end to the other end of the ceiling at regular intervals.

At each groove end, there are provided a blower 5 installed in the space 13 above the ceiling, a purifying device 7 consisting of a purifying filter 6, a suction port 4 connected by a duct 8 and a blowout port 3.

The blow-out port 3 is a groove blow-out port 3a which creates an air flow toward the suction port 4 in the groove 2 and an indoor blow-out port 3 provided at the tip of a duct extending in the floor direction along the wall surface.
It consists of b.

The indoor air outlet 3b has a height (1.1 from the floor) at which cigarette smoke is generated when a standing person smokes.
It is provided below m).

In the air purifying system according to the present invention, the installation position of the indoor air outlet 3b is not limited to the wall but may be provided on a part of the floor or the entire floor.

The location of the groove 2 may be a part of the ceiling 1 or the entire area of the ceiling 1.

Further, the directions of the grooves 2 do not have to be the same, for example, orthogonal directions.

[0019]

As described above, according to the air purification system of the present invention, the clean air supplied from the indoor air outlet is efficiently diffused to the entire room, especially to the source of the pollutants, and the entire groove is formed. Therefore, the effect of attracting the groove flow can be maintained, and the performance of collecting contaminants such as cigarette smoke can be improved.

Therefore, the cigarette smoke does not adversely affect the surrounding people.
