- the present invention provides an air deodorizer comprising the air cleaner of the present invention as described above and having at least the filter A in the air cleaner retain a deodorizing component.
- the air purifier of the present invention has a higher air purifying efficiency than known air purifiers, and therefore can reduce power consumption when exhibiting equivalent performance.
- FIG. 4 is a cross-sectional view of a filter in which bending widths are alternately long and short in one embodiment of the present invention.
- the air cleaner of the present invention surrounds an inner region including a disc, means for rotating the disc, and the rotation center of the disc provided on the disc.
- the filter A is a cylindrical filter as a whole, and includes a filter A bent in a wave shape so that irregularities are formed in the radial direction of the disk.
- FIG. 1 is an exploded perspective view of an embodiment of a filter A having a cylindrical shape as a whole
- FIG. 2 is a perspective view thereof.
- reference numeral 10 denotes a filter A bent in a wave shape
- 12 denotes an upper end plate fixed to the top of the filter A10
- 14 denotes a lower end plate fixed to the bottom of the filter A10.
- the upper end plate 12 and the lower end plate 14 are not essential, but are preferably provided because they exhibit the effect of preventing the deformation of the filter A due to the centrifugal force during rotation.
- cylindrical as a whole means that the wavy filter is not in the form of fine waves but is viewed macroscopically as shown in FIG. This means that the cylinder has a thickness (in the example shown in FIG. 2, the upper end plate 12 is a top surface and the lower end plate 14 is a bottom surface).
- Filter A10 surrounds an inner region including the center of rotation of a disc (described later), and has a shape bent in a wave shape so that irregularities are formed in the radial direction of the disc. This shape itself is known as described in Patent Document 2 and Patent Document 3. Partial enlarged views of preferred embodiments of the filter A10 are shown in FIGS.
- the tops inside the filter A10 may be cross-linked by a cross-linking band 16.
- the pitch of the top ridge line of each filter is fixed to about 1 to 10 mm, preferably about 2 to 5 mm by a bridging band.
- each top portion inside the wavy filter A ⁇ b> 10 is cross-linked by a hot melt adhesive layer 16 a which is a cross-linking band 16 (FIG. 1).
- the width of the hot melt adhesive layer (the width in the vertical direction) is usually about 1 to 3 mm, preferably about 2 mm. In the embodiment shown in FIG.
- each top portion of the inner side of the wavy filter A10 is about 0.2 to 1 mm thick on a sheet of paper, polypropylene, polystyrene, polyethylene, etc., which is a cross-linked band having a thickness of about 0.2 to 1.5 mm, preferably 0.7 mm.
- a relatively low melting point about 80 to 150 ° C.
- hot melt adhesive or polyethylene having a thickness of 0.5 mm is laminated
- These cross-linking bands may be one, but in order to effectively prevent the deformation of the filter A10 during rotation, it is preferable to provide a plurality (for example, four to ten if the filter height is about 80 to 200 mm). .
- the distance between the cross-linking bands is usually about 10 mm to 30 mm.
- the deformation of the filter A hardly occurs even if the cross-linking band is not provided.
- the folding width of the filter A10 may be uniform as shown in FIGS. 3 and 4, or may be alternately long and short as shown in FIG. As shown in FIG. 6, when the filter bending widths are alternately long and short, the opening area of the filter recess can be widened, so that a reduction in the air purification effect due to an increase in air resistance in this portion can be suppressed.
- the upper end plate 12 and the lower end plate 14 are, for example, about 0.2 to 1.5 mm thick, preferably about 0.7 mm thick paper or a sheet of plastic such as polypropylene, polystyrene, or polyethylene, preferably about 0.2 to 1 mm thick.
- the sheet melts and the end of the filter A10 and each end plate are bonded.
- a polyethylene sheet having a thickness of about 0.5 to 1.5 mm, preferably 1 mm, can be used as an end plate without being laminated, and can be fixed to the filter A.
- Each end plate is also useful for preventing deformation during rotation of the filter A, like the above-described cross-linking band. Therefore, instead of the cross-linking band or together with the cross-linking band, a plurality of cylindrical filters A10 shown in FIG. 2 are stacked. It can also be used (FIG. 5).
- FIG. 7 is an exploded perspective view of a preferred embodiment of the present invention.
- the above-described cylindrical filter A10 is provided on the disc 20 (note that a filter B described later is also drawn in FIG. 7).
- the filter A10 is fixed to the disc 20, and when the disc 20 rotates, the filter A10 also rotates at the same time.
- the filter A ⁇ b> 10 surrounds the inner region including the rotation center 20 a of the disc 20.
- the center of rotation is the center of the disk, and the center of the filter A10 coincides with the center of rotation 20a of the disk 20.
- the disc 20 has a central portion including a rotation center 20a for receiving a bearing of a means (motor or the like, not shown) for rotating the disc as shown in FIG. May protrude in a convex shape. What has such a shape also corresponds to the “disk” in the present invention.
- the disk 20 may be formed with one or a plurality of openings 20b for air circulation. At the center side of the rotating disk, the air moves to the outside due to the rotation of the air resistor, and therefore becomes negative pressure. For this reason, if there is the opening 20b on the center side of the disk, air flows in through the opening 20b, the air volume increases, and the air purification effect can be enhanced. In this case, air is supplied from the air suction hole 32a below the disk 20 (FIG. 14).
- an air resistor is provided on the disc.
- An “air resistor” is a structure that, when rotated together with a disk, increases the air flow that flows radially from the center of rotation of the disk on the principle of an impeller. By providing the air resistor, the flow rate of air passing through the filter A increases, so that the air cleaning efficiency can be increased.
- the air resistor may be arranged inside the filter A or outside. When arranged inside, the air resistor becomes an impeller and the air flow toward the filter A increases. Even when the air resistor is arranged outside the filter A, air is sucked from the outside of the filter A due to the principle of the impeller, so that the air flow toward the filter A is also increased.
- FIG. 7 is an exploded perspective view of a preferred embodiment of an air cleaner provided with a filter B22
- FIG. 8 is a perspective view thereof.
- the filter B22 is similar to the filter A and is preferably arranged coaxially with the filter A10.
- the filter B preferably has an upper end plate 24 at the upper end and a lower end plate 26 at the lower end. Note that the filter B has the same structure as the filter A described above, and all the descriptions of the filter A apply to the filter B as they are.
- a plurality of filters B may be provided.
- the filter B When the filter B is provided inside the filter A, the air flow toward the filter A can be increased by using the filter B as an impeller. In this case, since the amount of air supplied to the filter A increases, the air cleaning efficiency becomes higher than that of the filter A alone. Further, since the filter B itself is also a filter, the air is also cleaned by the filter B itself, so that the air cleaning efficiency is further increased.
- the filter B since air resistance is generated in the filter B when the air passes through the filter B, the amount of air supplied to the filter A may be reduced depending on conditions, and the total air cleaning efficiency may be reduced.
- the air resistance of the inner filter B equal to or less than the air resistance of the outer filter A, the air purification effect as a total filter unit (filter A and filter B) is enhanced. That is, the surface area of the filter is proportional to the diameter if the height of the filter is the same. Therefore, if the height is the same and the pitch of the filter irregularities is the same for the cylindrical filters A and B, the inner cylindrical filter B has a smaller surface area.
- the total opening area of the filter recess serving as an inlet when air flows into the filter is also proportional to the diameter. Therefore, if the height is the same and the pitch of the filter irregularities is the same between the cylindrical filters A and B, the inner cylindrical filter B has a smaller total opening area of the recesses. When there is almost no air gap between each filter, the amount of air passing through each filter is almost the same. Therefore, if the filter material is the same for the outer filter A and the inner filter B, the filter B has a higher air resistance. As a result, the air purification effect of the entire filter unit is limited. In this case, as described above, the air purification effect as a total filter unit can be enhanced by setting the air resistance of the inner filter B to be equal to or lower than the air resistance of the outer filter A. A coarse filter may be used to reduce the air resistance.
- the air passes through the upper side of the cylindrical filter B and reaches the cylindrical filter A as it is. By bypassing a part of the air in this way, it is possible to prevent the large air resistance of the cylindrical filter B from deteriorating the air purification effect of the entire filter unit.
- one or a plurality of wings provided on a disk preferably a plurality of wings can be mentioned.
- the wings can be provided instead of the filter B (FIG. 13), or can be provided in addition to the filter B (FIGS. 9 to 11).
- FIGS. 9 to 11 show a preferred embodiment in which a plurality of blades 28 are provided inside the filter B.
- the wings 28 are arranged radially about the rotation center 20a of the disc 20, and are arranged between the ridges of the convex portion of the disc 20 and the filter B22.
- the wings 28 are preferably arranged at substantially equal intervals around the rotation center 20a, for example, about 4 to 300 with an outer diameter of about ⁇ 500 mm. Since the wing 28 is also fixed on the disk, the wing rotates when the disk rotates.
- the wing 28 is integrally formed with the disc 20.
- the tip of the wing 28 opposite to the disk 20 has a ring 30 integrally formed with the wing 28 in order to prevent the wing 28 from bending outward due to centrifugal force when the disk rotates.
- a cylindrical filter B22 and a cylindrical filter A10 are attached in this order toward the outside of the disk 20.
- the lower end plate covers the inner edge of the filter B22 from the outer edge of the filter A10 and further overlaps with the disk 20, and is bonded at the overlapping portion.
- the side of the filter A and B opposite to the side where the disk 20 is bonded is fixed by the two upper end plates 12 and 24, respectively, but may be fixed together by one end plate.
- the rotation of the blades 28 increases the air flow supplied to the filter B22 by the impeller principle, which in turn increases the air cleaning efficiency.

That is, a is a sheet of paper having a thickness of about 0.2 to 1.5 mm, preferably 0.7 mm, or a plastic sheet such as polypropylene, polystyrene or polyethylene, b is a sheet having a relatively low melting point (about 80 to 150 ° C.) such as hot-melt adhesive or polyethylene having an end plate thickness of about 0.2 to 1 mm, preferably 0.5 mm, c is about 1 to 3 mm in thickness of the disc, preferably 2 mm in thickness, d and e are about 5 to 500 mm in height of the filter, preferably about 80 to 200 mm in height, f is about 5 to 500 mm in wing height, preferably about 80 to 200 mm in height, g is about 5 to 300 mm in width of the wing, preferably about 60 to 150 mm in width, h is a gap between the

The reason why the disk and the filter overlap the layer indicated by the thickness b is that the layer b is melted by heat at the time of welding, and the disk and the filter are eroded.
- the blades indicated by height f and width g are parallelograms because of the draft angle during injection molding.
