Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air purifier, and more particularly to an air purifier for removing locally generated air pollutants such as cigarette smoke.

In recent years, as buildings have become more airtight, it has become increasingly necessary to remove various air pollutants such as cigarette smoke and solder fumes, and cigarette smoke has also become a problem in automobiles, trains, airplanes, etc. It is becoming.

In order to remove such air pollutants, the conventional method has been to suck indoor contaminated air into an air purifier and purify it, but with this method, the pollutants are diffused throughout the room before being purified. Therefore, sufficient effects could not be obtained unless the air purifier had a large processing air volume.

When air pollutants are generated locally, it is effective to place the suction port of the air purifier close to the source of the pollutants. If a contaminant occurs, it will quickly spread by drawing in the surrounding air, so if the source of the contaminant is moved a little away from the suction port, the amount of contaminants that will flow away without being suctioned will increase, and the removal effect will sharply decrease. If the size is increased, the suction speed decreases, which has the disadvantage that it flows away before being suctioned.

In addition, there is a so-called annular suction port around the front lid of the air purifier that sucks air with a gap, but in this case, the suction speed is zero at the center of the front lid, so some smoke comes out from the mouth like cigarette smoke. The drawback was that the smoke that was blown out at such a high velocity would rise above the front lid and flow away to areas other than the suction port.

The present invention eliminates the drawbacks of conventional devices and provides an air purifier for locally generated pollution sources that has a small amount of air to be processed, can be made portable and compact, and exhibits an excellent cleaning effect. It is.

Next, the configuration of the present invention will be explained based on the drawings.

FIG. 2 is a sectional view of one embodiment of the present invention, and FIG. 3 is a perspective view of the embodiment in use.

The air purifier of the present invention shown in these figures is composed of an air purifier main body 9 and a planar suction member 10 which is attached and housed with a lid formed on the air purifier main body. The air purifier body 9 includes an electrostatic precipitator 5 for removing suspended particulate air pollutants such as smoke, and an adsorption treatment agent layer for removing gaseous air pollutants such as solvent vapor. 6 and blower 8
A planar suction member 10 for supplying contaminated air to the purifying means includes a cylindrical suction member 10 provided in the center of one edge thereof. Connecting parts 1 are provided at both ends of the connecting part 17 having a shape, and at both ends of one edge of the air purifier main body 9.
By inserting and connecting two annular protrusions 18, 18 formed uniaxially at the tips of 6, 16,
It is designed so that it can be rotated uniaxially relative to the air purifier main body and displaced and fixed at any position while the flow path is formed with the purifying means.

In addition, the suction surface 21 of the planar suction member 10 is formed by connecting the entire surface of one surface of the planar suction member in the form of a flat box to the perforated plate 1.
3, and the perforated plate is formed by increasing the areal density of the small holes 14 at the periphery and decreasing it at the center, so that the amount of intake air per unit area on the suction surface can be reduced. 21 is larger at the periphery than at the center.

FIG. 4 is a sectional view of another embodiment of the planar suction member for the air purifier of the present invention, and the planar suction member shown in this figure also has the surface shown in FIGS. Like the shaped suction member, it is attached to the main body of the air purifier so that it can rotate around one axis, but the perforated plate 13 that makes up the suction surface has small holes 14 with a large opening area on the periphery, and A small hole 14 with a small area is provided in the center so that the amount of air taken in per unit area on the suction surface increases around the area.

FIG. 5 is a cross-sectional view of still another embodiment of the present invention. In the air purifier main body 9 that has a built-in
The planar suction member 10
The planar suction member 10 can be fixed at any position relative to the air purifier main body 9 by means of the telescopic joint 26.

Further, the planar suction member 10 has a box shape, and by making one wall of the box a breathable member 27 such as sponge or felt material, suction can be carried out over the entire surface. The air-permeable member is thick at the center and thin at the periphery, so that the amount of air taken in per unit area at the periphery of the suction surface is increased.

As shown in the above embodiments, the present invention provides an air purifier comprising means for purifying contaminated air containing smoke, etc., and a planar suction member for sucking and supplying the contaminated air to the purifying means. The suction device is characterized in that the amount of air sucked per unit area on the suction surface of the suction member is large in the periphery of the suction surface.

Next, the effects of the present invention will be explained.

As shown in each embodiment, the suction member 10 of the present invention is a planar suction member that sucks air over the entire surface, so even if contaminated air with a certain flow velocity is sprayed, like cigarette smoke exhaled during smoking, the suction member 10 will not cover the entire surface. Since it is sucked across, it does not fly up on the suction surface.

Moreover, the planar suction member of the present invention is shown by the solid line A in FIG.
As shown in Figure 2, the amount of air taken per unit area on the suction surface is larger at the periphery than at the center of the suction surface, so the contaminated air that cannot be fully taken in at the center flows toward the periphery along the suction surface. While flowing, the air is eventually completely absorbed in the peripheral area where there is a large amount of intake air.

Thus, in the present invention, since the amount of contaminated air flowing outside is not small, an excellent cleaning effect is exhibited despite the small processing air volume. It is an object of the present invention to provide an air cleaner that eliminates the above-mentioned conventional drawbacks.
