Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaner for collecting and treating contaminants such as cigarette smoke.

[0002]

2. Description of the Related Art Conventionally, as this type of air cleaner, as shown in FIG. 3, an electric dust collector type air cleaner 11 which is formed in a panel shape and has an outlet 3 and an inlet 4 on its surface. The product that incorporates is commercialized. Also, FIG.
As shown in (JP-A-1-168316), the outlet 3
There is known an air purification device in which the suction port 4 faces each other.

[0003]

In the air cleaner shown in FIG. 3, the cigarette smoke 8a in the vicinity of the suction port 4 is sucked, but the slightly displaced cigarette smoke 8b is attracted by the blowing air current and scattered into the room. Further, in the air purifying apparatus shown in FIG. 4, the airflow between the outlet 3 and the inlet 4 is disturbed by the airflow generated in the room, and the tobacco smoke is not stably collected,
It is scattered in the room. Arrows in FIGS. 3 and 4 indicate the flow of air flow.

The present invention has been made in view of the above problems, and an object of the present invention is to stably collect and process cigarette smoke without scattering it into a room.

[0005]

In order to achieve the above object, in the air cleaning apparatus of the present invention, at least one of the panels 9 installed so as to surround the desk 1 is provided in the air passage c in the panel 9. An outlet 3 having a purifying filter a and a blower b, which communicates with the air passage c below the top plate 2 of the desk 1, and a suction port 4 which communicates with the air passage c above the top plate 2 side.
And a blow-off port 5 for forming an air flow in the direction of the suction port 4 along the wall surface of the panel 9 at a constant distance from the suction port 4, and a shut-off blow-off port 7 at a side end not in contact with another panel. The air purification device is characterized by being provided with.

[0006]

[Operation] Smoke rising from the cigarette placed on the desk 1 (hereinafter referred to as sidestream smoke) is attracted to the airflow from the outlet 5,
It flows along the wall surface of the panel 8, is sent from the suction port 4 of the panel 8 to the air purifying means inside the panel 8, and after being purified, part of it is sent to the blowing port 5 and the other is sent to the blowing port 3 to supply it to the room. Be worried.

Further, cigarette smoke (hereinafter referred to as mainstream smoke) exhaled from the smoker's mouth is purified by the smoker toward the panel 9 in the same manner as the sidestream smoke. Blocked by the air flow from the outlet 7 at the side end,
The inflow air flow from the side end to the desk 1 is restricted.

[0008]

1 and 2, among the partition panels 9 installed so as to surround the desk 1, the inside of the panel 9 on the left side facing the desk is hollow and a slit-shaped opening is provided on the upper side of the desk 1. It is provided as a contaminated air suction port 4, and an opening is provided at the same height as the top plate 2 on the desk 1 side of the panel 9 so as to face the contaminated air suction port 4, as an outlet 5 for attracting airflow. A U-shaped guide 6 is installed in such a manner that one of the guides 6 is inserted into the panel 9 so that the outlet 5 for the induced airflow faces the contaminated air inlet 4. Further, a relatively large opening is provided as a blow-out opening 3 on the lower side around the panel 9, and a slit-shaped opening is formed from the height position of the top plate 2 of the desk 1 on the side end face not in contact with the front partition panel 9 to the upper end. Are provided as blow-off airflow ports 7, and the respective openings are connected to the hollow portion inside the panel 9 as an air passage c, and the contaminated air suction port 4 and the induced air flow outlet port 5 in the air passage c are connected. An air purifying means including an air purifying filter a and a blower b is provided between them so that part of the purified air flows to the blowout port 7 through the air passage c.

The amount of air discharged from the blow-out port 5 is about 20% of the circulating air amount (it varies depending on the distance between the blow-off port 5 of the induced airflow and the suction port 4 of the contaminated air), and the wind speed is the suction port 4 of the contaminated air. And the remaining air is supplied from the outlets 3 and 7 into the room.

When the air purifying apparatus is installed on the left side of the desk and the ordinary panel is installed on the front surface of the desk, when smoking, the air flow is generated on the left and front of the smoker by the panel. The airflow that is blocked by 9 and that comes from the rear, right, and above becomes the airflow toward the suction port 4. However, the air flow from the left rear of the smoker acts so as to scatter the cigarette smoke 8 generated on the desk in the room, but the air flow of the blowout port 7 blocks the inflow to the desk 1 so that it is located near the air purifier. The sidestream smoke rising from the cigarette is attracted to the airflow from the outlet 5 beside the top plate 2 of the desk 1 and the panel 9
Ascends along the wall surface and is sent from the contaminated air suction port 4 at the top of the panel 9 to the air purification section inside the panel 9, and after being purified, part is sent to the outlet 5 and the other is sent to the outlet 3. Is supplied to the room.

The mainstream smoke exhaled from the smoker's mouth is purified by the smoker toward the panel 9 installed on the left side of the desk 1 in the same manner as the sidestream smoke.

[0012]

As described above, according to the air purification apparatus of the present invention, cigarette smoke generated even when smoking at a desk such as an office is efficiently collected and treated without being scattered around. It does not have a negative physical, sensory, or psychological effect on the surrounding people.
