  The deodorizing apparatus according to claim 1 of the present invention includes a main body provided with an inlet and an outlet, an air air passage communicating the inlet and the outlet in the main body, and air to the air air passage. A blowing means for flowing, a rotatable disc-shaped deodorizing filter provided so as to block the air air passage, a driving unit for rotating the deodorizing filter, and the deodorizing filter rotated by the driving unit for stored water The deodorizing filter has a filter medium having a lattice in which a water film is formed in a portion soaked in water, and is arranged in a double manner at intervals in the ventilation direction. The drive unit rotates one of the deodorizing filters clockwise and the other counterclockwise.

  As a result, the lattice on which the water film is formed forms a water film on the entire filter medium, so that when the odor component passes through the filter medium, it penetrates the water film or comes into contact with the water film and dissolves in water. Done. In particular, due to the double arrangement with a gap in the ventilation direction, the clockwise deodorizing filter can be used counterclockwise in the downstream part even if the wind passes through the upstream part in the clockwise direction and the water film disappears. Since a water film is generated upstream of the deodorizing filter, air can penetrate through the water film or contact the water film in the entire cross section of the air air passage, and the deodorizing component passing through the filter is almost dissolved in water. Can be made.

  Further, the deodorizing apparatus according to claim 2, wherein the deodorizing filter includes a disc-shaped central axis as a rotation axis, and is formed on the first surface in a coronal shape outside the rotation axis and inside the outer edge. The deodorizing filter is arranged as a first deodorizing filter and a second deodorizing filter with the first surfaces facing each other, and the drive unit is a motor and the rotation of the motor It comprises a second gear provided on the shaft, and the second gear meshes simultaneously with the first gear of the first deodorizing filter and the second deodorizing filter.

  Accordingly, the first deodorizing filter and the second deodorizing filter can be driven to rotate in the opposite directions relatively with one drive unit, and a water film is formed on the two filters without a complicated mechanism. Can do.

  The deodorizing apparatus according to claim 3, wherein the first deodorizing filter out of the deodorizing filters includes a cylindrical protruding bar protruding in a cylindrical shape inside the first gear, and a columnar shape protruding on a second surface.

A rotary shaft projecting in a cylindrical shape on the surface, and the first deodorizing filter and the second deodorizing filter are engaged with the cylindrical projecting bar and the plate-shaped projecting bar so as to be rotatable at a predetermined distance. To do.

  Thereby, since the rotating shaft is formed integrally with the deodorizing filter, it is not necessary to remove the filter frame at the time of cleaning, and it can be easily maintained. In addition, the two filters can be easily integrated by locking and holding the cylindrical protrusion and the plate-like protrusion. Further, the plate-like protruding bar has a small contact area with the inside of the cylindrical protruding bar, and friction hardly occurs during rotation. Therefore, the force applied to the rotation is reduced, and the load on the motor can be reduced.

  Moreover, the deodorizing apparatus of Claim 4 maintains the height of a water surface so that an outer peripheral side can be flooded rather than said 1st gearwheel.

  Thereby, the whole grating | lattice in which a water film is formed by a deodorizing filter rotating can be immersed in a tray, and a water film can be formed in the whole grating | lattice. Furthermore, the scale generated by vaporization is difficult to adhere, and a water film can be formed for a long time.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1, a suction port 2 is provided on the front surface of the main body of the deodorizing apparatus 1, and an air outlet 3 is provided on the upper part. In the body, an air air passage 4 communicating the suction port 2 and the air outlet 3 is formed, a deodorizing filter 5 is disposed in the air air passage, and between the deodorizing filter 5 and the air outlet 3 in the air air passage 4. A blower means 6 for flowing air is arranged.

  The deodorizing filter 5 has a disc shape, and is arranged so that the upper part of the disc-shaped filter medium 8 is shielded from the air air passage and the lower part is immersed in the water tank 7. The deodorizing filter 5 has a filter medium 8 provided with a lattice in which a water film is formed in a portion immersed in water within a predetermined range from the outer periphery toward the disc-shaped central axis. Thereby, when the filter medium 8 moves from the water to the air, a water film is formed on the net-like lattice constituting the deodorizing filter 5.

  According to the above configuration, the air sucked from the suction port 2 by the blowing means 6 collides with the water film of the deodorizing filter 5 provided in the air air passage 4 when passing through the deodorizing filter 5 and penetrates the water film. Alternatively, by contacting the water film, odor components contained in the air are removed and deodorization is performed. The deodorized air that has passed through the deodorizing filter 5 is discharged from the outlet. Deodorization is performed by contacting water in the water film, so that air passes through the water film without breaking the water film, and air breaks through the water film and passes through the lattice. But it can be deodorized.

  In this way, when the air containing the odor component passes through the formed water film, the odor component dissolves in the water film, and deodorization is performed without performing a complicated mechanism.

  Now, as shown in FIG. 2, in this Embodiment, the deodorizing filter 5 is double-arranged as the 1st deodorizing filter 9a and the 2nd deodorizing filter 9b at intervals in the ventilation direction.

  The first deodorizing filter 9 a has a disc-shaped central axis as the rotation axis 10.

  A first surface 11 located on the inner side and a second surface 12 located on the outer side are provided. The second surface 12 located outside is a surface provided with the rotation shaft 10.

  As shown in FIG. 3 (A), the first surface 11, which is the surface opposite to the second surface 12, has a first gear 13 on the outer side of the rotary shaft 10 and on the inner side of the outer edge. A disc portion 14 formed in a crown shape is provided. The disk portion 14 is a region closer to the central axis than the portion having the filter medium. Moreover, the disk part 14 is formed with the material which does not have air permeability.

  Further, a cylindrical protruding bar 15 which is a bearing protruding in a cylindrical shape is provided inside the first gear 13. The first gear 13 is a bevel gear.

  The second deodorizing filter 9b has a disc-shaped central axis as the rotation axis 10 in the same manner as the first deodorizing filter 9a.

  As shown in FIG. 3B, the first surface 11, which is the surface opposite to the second surface 12, is provided with a plate-like protruding bar 16 disposed outside the rotating shaft 10. The plate-like protruding bars 16 are rotary shafts arranged radially so as to be engaged with the inside of the cylindrical protruding bars 15 provided in the first deodorizing filter 9a. In order to ensure a small contact area and strength in consideration of friction with the cylindrical protruding bar 15 during rotation, the plate-shaped protruding bar 16 has a cross section perpendicular to the rotating shaft 10 as shown in FIG. It is desirable that they are arranged in a cross shape, that is, a shape in which two plate pieces intersect or a radial shape from the rotation axis 10.

  The material of the filter medium 8 may be hydrophilic or hydrophobic, as long as it is hydrophilic, such as cellulose or other paper or wood processed into a corrugated shape, silk, wool or cotton. -Natural fibers such as hemp, synthetic fibers such as rayon, acetate, and triacetate in a corrugated shape, ceramic honeycombs having water absorption, and the like can be used. Examples of synthetic fibers include polyester, acrylic, nylon, vinylon, rayon, polynosic, cupra, acetate, triacetate, and promix. Examples of natural fibers include silk, hair, cotton, and hemp. Polyvinyl acetate, polyvinyl alcohol sponge, nylon microfiber, etc. may be used. Paper such as cellulose and woody materials, natural fibers such as silk, wool, cotton, and linen, synthetic fibers such as rayon, acetate, and triacetate, and water-absorbing ceramics may be used.

  The material of the rotary shaft 10 and the disk part 14 of the filter may be any material as long as the shape of the disk part 14 itself can be maintained and the filter medium 8 can be supported, and a resin such as PE, PP, PET, or ABS is used. be able to.

  According to the said structure, as shown in FIG. 4, by engaging the cylindrical protrusion 15 with which the 1st deodorizing filter 9a is equipped, and the plate-like protrusion 16 with which the 2nd deodorizing filter 9b is provided, The plate-like protruding bar 16 is combined with the cylindrical protruding bar 15 so that the first deodorizing filter 9a and the second deodorizing filter 9b are integrated.

  Accordingly, the two filters can be easily integrated by holding the cylindrical protruding bars 15 and the plate-shaped protruding bars 16. Further, since the plate-like protruding bar 16 has a small contact area with the inside of the cylindrical protruding bar 15 and friction is less likely to occur during rotation, the force applied to the rotation is reduced and the load applied to the motor 18 can be reduced.

  Further, as shown in FIG. 5, a second gear 17 is provided so as to simultaneously mesh with the first gear 13 of the first deodorizing filter 9 a and the second deodorizing filter 9 b, and the second gear 17 is a motor 18. Is provided on the rotating shaft. The second gear 17 is a bevel gear for meshing with the first gear.

  According to the above configuration, one of the deodorizing filter 5 is rotated clockwise and the other is rotated counterclockwise by the drive unit 19 in which the motor 18 and the second gear 17 are integrated.

  Further, by arranging the air filter in the airflow direction at intervals, the clockwise deodorizing filter 5 is counterclockwise in the downstream portion even if the wind passes through the upstream portion in the clockwise direction and the water film disappears. A water film is generated at the upstream portion of the deodorizing filter 5.

  That is, one of the deodorizing filters 5 in the double can hold the water film, and a state in which the water film is always formed on the entire ventilation surface can be created. That is, air can penetrate through or contact with the water film over the entire cross section of the air air passage, and the deodorizing component that passes through the filter can be substantially dissolved in water.

  In the present embodiment, bevel gears are used for the first gear 13 and the second gear 17, but the gears only need to have an intersecting axis, and a combination of spur gears may be used. Further, as long as the tooth pitch is matched and meshed, a combination of different gears may be used, for example, a combination of a spur gear or a helical gear. Furthermore, this time, the method of rotating two filters with one gear is used, but it is also possible to install one gear for each rotation direction of the filter and rotate the two filters in the opposite direction.

  As shown in FIG. 6, the water surface 20 of the water tank is configured such that the outer peripheral side of the first gear 13 can be submerged, and the outer peripheral portion of the first gear 13 is rotated when the deodorizing filter 5 is rotated. Is a positional relationship that exists directly above the water surface.

  As a result, the entire lattice on which the water film is formed can be immersed in the tray by the rotation of the deodorizing filter 5, and the water film can be formed on the entire lattice of the filter medium. Furthermore, the scale generated by vaporization is difficult to adhere, and a water film can be formed for a long time.

(Embodiment 2)
Next, the plate-like protruding bars 16 indicate the shape of the plate-like protruding bars 16 in order to reduce the contact area and reduce the strength in order to reduce the contact area in consideration of the friction against the cylindrical protruding bars 15 during rotation.
As shown in FIG. 7A, in a cross section perpendicular to the rotation axis 10, it is desirable to arrange in a cross shape, that is, a shape where two plate pieces intersect, or radially from the rotation axis 10. Further, as shown in FIG. 7B, a cross-shaped plate can be arranged with the cross-shaped being dispersed in several places. Alternatively, as shown in FIG. 7C, a shape having curved plates at both ends of the plate may be used.

  Further, the contact portion with the inside of the cylindrical protruding bar 15 on the plate-shaped protruding bar 16 in FIGS. 7A and 7B may be a curved surface. Thereby, by reducing the contact area, the friction applied during rotation can be reduced, and the burden on the motor can be reduced.

  As described above, the present invention includes a main body provided with an inlet and an outlet, an air air passage communicating the inlet and the air outlet in the main body, and a blowing means for flowing air to the air air passage. A rotatable disc-shaped deodorizing filter provided so as to block the air air passage, a driving unit for rotating the deodorizing filter, and a lower part of the deodorizing filter rotated by the driving unit in stored water. The deodorizing filter includes a filter medium having a lattice in which a water film is formed in a portion immersed in water, and is arranged in a double manner with a gap in the ventilation direction. And the drive unit rotates one of the deodorizing filters clockwise and the other counterclockwise.

  As a result, the lattice on which the water film is formed forms a water film on the entire filter medium, so that when the odor component passes through the water film, it dissolves in water and deodorizes. In particular, due to the double arrangement with a gap in the ventilation direction, the clockwise deodorizing filter can be counterclockwise in the downstream part even if the wind passes through the upstream part in the clockwise direction and the water film disappears. Since a water film is generated in the upstream portion of the deodorizing filter, a water film can always be formed on the entire ventilation surface of the odor component, and almost all of the deodorizing component passing through the filter can be dissolved in water. Therefore, it is utilized as a deodorizing device.
