In the fan deodorizer, the flow velocity of the air flowing from the rear guard to the blades of the commercial fan is slow, and the air flows slowly through the deodorizing cartridge, so the contact time of the air with the deodorizing cartridge can be lengthened. odors can be reliably removed. With deodorizing equipment for fans, indoor air passes through the deodorizing cartridge while the commercial fan is in operation, then passes through the deodorizing cartridge again, and the air circulates (circulates) through the deodorizing cartridge repeatedly, so the indoor air is deodorized. It is gradually purified by the cartridge, and the deodorizing function can be sufficiently exhibited by operating the commercial fan for a long time.

With reference to the attached drawings such as FIG. 1, which is a perspective view of a commercial fan 11 to which the fan deodorizer 10 is attached as an example, the details of the fan deodorizer and the hanging jig according to the present invention will be described. They are as follows. 2 is a front view of the commercial fan 11 to which the fan deodorizer 10 is attached, and FIG. 3 is a rear view of the commercial fan 11 to which the fan deodorizer 10 is attached. FIG. 4 is a side view of the commercial fan 11 to which the fan deodorizer 10 is attached, and FIG. 5 is a top view of the commercial fan 11 to which the fan deodorizer 10 is attached. 2 and 4, the radial direction is indicated by an arrow X, the circumferential direction by an arrow Y, and the front-back direction by an arrow Z. As shown in FIG.

The fan deodorizer 10 is detachably attached to the rear of the rear guard 13 of the commercial fan 11 and immediately behind the motor case 15 (rear in the front-rear direction), and the odor (odor) contained in the air flowing through the commercial fan 11 is removed. It is suitably used for removing components, tobacco odor, nonenal odor) and removing pollen and viruses. A deodorizing device 10 for an electric fan is composed of a deodorizing cartridge 16 for removing odors contained in the air and a hanging jig 17 for hanging the deodorizing cartridge 16 just behind a motor case 15.例文帳に追加

The deodorizing cartridge 16 is arranged immediately after the motor case 15 of the commercial fan 11 and deodorizes the malodorous components of the air flowing into the blades 18 from the rear guard 13 of the commercial fan 11 . The deodorizing cartridge 16 is made of a flexible polyurethane foam (not shown) having a predetermined thickness and having open cells, activated carbon powder (not shown) that adsorbs odors, and a support frame 19 that supports the flexible polyurethane foam. . The same flexible polyurethane foam as that disclosed in JP-A-2016-98699 can be used.

Flexible polyurethane foams are polyether foams made from tolylene diisocyanate and polyether polyol, or polyester foams made from tolylene diisocyanate and branched polyester polyol. Flexible polyurethane foams are made by adding additives used for adjusting the cell diameter to the foam raw material, and foaming is carried out with water and a foaming aid. The flexible polyurethane foam has open cells, a predetermined thickness, and is elastically deformable and flexible. The flexible polyurethane foam is coated with activated carbon powder (not shown).

The flexible polyurethane foam comprises an air outflow front surface with a circular planar shape and a predetermined area, an air inflow rear surface with a circular planar shape and a predetermined area, an outer peripheral edge portion extending annularly in the circumferential direction, and a plurality of vents extending between the front and rear surfaces. and a plurality of vents connected to the vent path and open to the front and rear surfaces. The planar shapes of the air outflow front surface and the air inflow rear surface are not limited to circular shapes, and may be square, rectangular, polygonal, elliptical, or other shapes.

The air channels are defined within the polyurethane foam surrounded by flexible polyurethane foam walls. A coating layer of activated carbon powder is formed on the walls defining the air passage. The air passages extend irregularly in the thickness direction of the flexible polyurethane foam between the air outflow front surface and the air inflow rear surface, and between the outer peripheral edge of the polyurethane foam and the center of the polyurethane foam. It extends while irregularly bending in the radial direction of the

The air passages that are radially adjacent to each other and extend in a curved manner in the thickness direction are partially connected in the radial direction, and one air passage communicates with the other air passage. The air passages that are adjacent to each other in the thickness direction and bend in the radial direction are partially connected in the thickness direction, and one air passage communicates with the other air passage. The opening area of these air passages is not uniform in the thickness direction, but varies irregularly in the thickness direction. is changing. The air passages are irregularly opened in the thickness direction and radial direction while the opening area increases and decreases. Moreover, the areas of the vents connected to the vent paths are not uniform, but differ.

The flexible polyurethane foam has a thickness dimension in the range of 5 to 20 mm, preferably in the range of 8 to 15 mm. If the thickness dimension of the flexible polyurethane foam is less than 5 mm, the specific surface area of the wall surface of the polyurethane foam cannot be increased, and the deodorizing cartridge 16 (soft polyurethane foam coated with activated carbon powder or flexible polyurethane foam mixed with activated carbon powder, which will be described later). can not improve the odor adsorption function of When the thickness dimension of the flexible polyurethane foam exceeds 20 mm, the air resistance of the deodorizing cartridge 16 (soft polyurethane foam) is large, and the deodorizing cartridge 16 acts as a resistance to the air flowing into the commercial fan 11, causing air to flow into the commercial fan 11. cannot flow smoothly.

Since the thickness dimension of the flexible polyurethane foam is within the above range, the specific surface area of the wall surface of the polyurethane foam can be increased, and the deodorizing cartridge 16 (soft polyurethane foam coated with activated carbon powder or soft polyurethane foam mixed with activated carbon powder) can be used. It is possible to improve the odor adsorption function, and the odor components, tobacco odor, nonenal odor, pollen, and viruses contained in the air flowing into the commercial fan 11 are mixed with the activated carbon powder applied to the polyurethane foam and the polyurethane foam 20. It can be reliably adsorbed on the activated carbon powder. Also, the deodorizing cartridge 16 (soft polyurethane foam) does not act as a resistance to the air flowing into the commercial fan 11, and the air can flow smoothly into the commercial fan 11. - 特許庁
Flexible polyurethane foams have a mass in the range of 30-80 g. The weight of the soft polyurethane foam in the deodorizing cartridge 16 is within the above range, and the weight of the deodorizing cartridge 16 can be reduced. By suspending the deodorizing cartridge 16 by the suspending jig 17 , the deodorizing cartridge 16 suspended by the suspending jig 17 can be arranged behind the rear guard 13 of the commercial fan 11 .

Furthermore, the deodorizing cartridge 16 ( support frame ) can be easily attached to the hanging jig 17 (commercial fan 11), and the deodorizing cartridge 16 (support frame) can be easily removed from the hanging jig 17 (commercial fan). It is possible to easily remove the deodorizing cartridge 16 from the fan 11 for business use and to replace it.

The flexible polyurethane foam has a surface velocity in the range of 20-40 cm/sec, preferably in the range of 25-35 cm/sec. If the surface velocity of the flexible polyurethane foam is less than 20 cm/sec, the air cannot smoothly flow through the deodorizing cartridge 16 (soft polyurethane foam), and the deodorizing cartridge 16 (soft polyurethane foam) prevents air from flowing into the commercial fan 11. , and the air cannot smoothly flow into the fan 11 for business use. When the surface velocity of the flexible polyurethane foam exceeds 40 cm/sec, the air quickly passes through the polyurethane foam ventilation channel, and the air cannot sufficiently contact the wall surface of the polyurethane foam ventilation channel, resulting in odors contained in the air. Ingredients, tobacco odor, nonenal odor, pollen, and viruses cannot be sufficiently adsorbed to the activated carbon powder applied to the polyurethane foam or to the activated carbon powder kneaded into the polyurethane foam.

Since the surface velocity of the soft polyurethane foam of the deodorizing cartridge 16 is within the above range, the deodorizing cartridge 16 (polyurethane foam) does not act as resistance to the air flowing into the commercial fan 11, and the air flows smoothly into the commercial fan 11. , and the clean air can be smoothly blown to the front of the commercial fan 11. - 特許庁In addition, the air that has flowed into the commercial fan 11 does not quickly (instantaneously) pass through the air passage of the flexible polyurethane foam, and the air can sufficiently contact the wall surface of the air passage of the polyurethane foam. The activated carbon powder applied to the polyurethane foam and the activated carbon powder mixed in the polyurethane foam can surely adsorb the odorous components, tobacco smell, nonenal smell, pollen, and viruses.

The soft polyurethane foam has an air outflow front surface and an air inflow rear surface area smaller than the areas of the rear guard 13 and the front guard 12 of the commercial fan 11 . The areas of the air outflow front surface and the air inflow rear surface may be substantially the same as the areas of the rear guard 13 and the front guard 12 of the commercial fan 11 . The flexible polyurethane foam is entirely covered with an air-permeable net 29 (non-woven fabric, woven fabric, knitted fabric, net) having a plurality of meshes. For the breathable net 20, a mesh number of 10 meshes (100×100 meshes), 12 meshes (120×120 meshes), 24 meshes (240×240 meshes), 32 meshes (320×320 meshes), etc. is used. can be done.

The activated carbon powder is adhered to the wall surfaces of the flexible polyurethane foam (air outflow front surface, air inflow rear surface, wall surface of the air passage) with a predetermined binder (adhesive). One example of applying (fixing) activated carbon powder to the air outflow front surface, the air inflow rear surface, and the wall surface of the flexible polyurethane foam is to allow air to flow from one surface of the polyurethane foam to the other surface while the activated carbon powder and the binder are combined. is spray coated onto one side of the polyurethane foam and the mixed paint is allowed to dry. Another example of applying (fixing) activated carbon powder to the wall surface of flexible polyurethane foam is to dip polyurethane foam into a mixed paint of activated carbon powder and binder, and then dry the mixed paint. In the flexible polyurethane foam coated with activated carbon powder, the activated carbon powder is layered on the wall surface, and the activated carbon coating layer is formed on the wall surface.

Another example of a flexible polyurethane foam is an open-celled polyurethane foam made by foaming a foam raw material mixed with activated carbon powder. The flexible polyurethane foam mixed with activated carbon powder is entirely wrapped in the air-permeable net 20 (packaging sheet) having the mesh number. In a flexible polyurethane foam obtained by foaming a foam raw material mixed with activated carbon powder, the activated carbon is exposed on the walls of the polyurethane foam. The flexible polyurethane foam mixed with activated carbon powder has a predetermined thickness, is flexible, and is elastically deformable. The mixing ratio of the activated carbon powder to the foam material is 80 to 180% by weight of the activated carbon powder to 100% by weight of the foam material, preferably 100 to 150% by weight of the activated carbon powder to 100% by weight of the foam material.

Activated carbon powder has a specific surface area of about 300 to 5000 m ² /g and has a high odor adsorption function (including a radioactive substance adsorption function such as iodine and gaseous cesium). Activated carbon powder is made by pulverizing activated carbon, and its average particle size is in the range of 5 to 10 μm. Activated carbon to be processed into activated carbon powder is made from raw materials such as coconut shells, sawdust, hard wood chips, charcoal and grass charcoal.

When the circular air outflow front surface of 16 is inclined and the posture of deodorizing cartridge 16 with respect to commercial fan 11 is changed, at least one of first hook 26 and second and third hooks 27 and 28 is plastically deformed. By bending the hooks 26 to 28 to change the angle of the hooks 26 to 28, and by changing the angle of the air outflow front surface of the deodorizing cartridge 16 with respect to the rear guard 13 of the commercial fan 11, the rear guard 13 of the commercial fan 11 can be used to make the air outflow front surface of the deodorizing cartridge 16 parallel.

Furthermore, when the distance between the deodorizing cartridge 16 (support frame 19) and the motor case 15 of the commercial fan 11 is reduced, at least one of the first hook 26 and the second and third hooks 27, 28 is plastic. The length of the folded back of the hooks 26 to 28 is increased by deformation, and the distance between the first hook 26 and the second and third hooks 27, 28 in the front-rear direction (the distance in the front-rear direction of the first and second arms 29, 30) is increased. ), the distance between the deodorizing cartridge 16 (support frame 19) and the motor case 15 of the commercial fan 11 can be reduced. By reducing the distance between the deodorizing cartridge 16 and the motor case 15 , the deodorizing cartridge 16 can be positioned near the rear of the motor case 15 .

When the deodorizing cartridge 16 is too close to the motor case 15 after increasing the folding length of the hooks 26 to 28 to reduce the distance between the deodorizing cartridge 16 and the motor case 15, the folding length of the hooks 26 to 28 is increased. By reducing the length, the distance between the first hook 26 and the second and third hooks 27, 28 in the front-rear direction (length dimension in the front-rear direction of the first and second arms 29, 30) is increased, The distance between the deodorizing cartridge 16 (support frame 19) and the motor case 15 of the commercial fan 11 can be increased.

The fan deodorizer 10 deodorizes by plastically deforming the first and second arms 29 and 30 made of plastically deformable elongated metal rods to deform the arms 29 and 30 in a curved or linear shape. Since the position of the cartridge 16 (support frame 19) with respect to the commercial fan 11, the posture with respect to the commercial fan 11, and the distance between the deodorizing cartridge 16 (support frame 19) and the motor case 15 of the commercial fan 11 can be changed, The deodorizing cartridge 16 can be positioned behind the rear guard 13 so that the circular air outflow front surface of the deodorizing cartridge 16 covers the rear guard 13 of the commercial fan 11, and is positioned against the rear guard 13 of the commercial fan 11. The air outflow front surface of the deodorizing cartridge 16 can be made parallel, and the distance between the air outflow front surface of the deodorizing cartridge 16 and the rear guard 13 of the commercial fan 11 can be optimized.

It flows into the inside of the deodorizing cartridge 16 . Air flowing into the interior of the deodorizing cartridge 16 from the air inflow rear surface of the deodorizing cartridge 16 passes through the ventilation net 20, and a plurality of ventilation holes extending between the front and rear surfaces of the polyurethane foam from the ventilation openings opened in the air inflow rear surface of the flexible polyurethane foam. enter the road. The air that has entered the ventilation path contacts (collides) with the wall surface forming the ventilation path, passes through the ventilation path, flows out from the ventilation opening that opens in front of the air outflow of the flexible polyurethane foam, and passes through the ventilation net 20. The deodorizing cartridge 16 is opened toward the rear guard 13 of the commercial fan 11 from the rear surface of the air outflow.

The air that has entered the air passages of the flexible polyurethane foam contacts (collides) with the wall surfaces of the air passages that extend irregularly in the thickness direction and the radial direction inside the flexible polyurethane foam, and the odorous components contained in the air ( Ammonia, basic odor components mainly composed of nitrogen-containing compounds such as trimethylamine, triethylamine, and trialamine, sulfur-containing compounds such as hydrogen sulfide, methyl sulfide, methyl disulfide, and methyl mercaptan, formaldehyde, acetaldehyde, butyraldehyde, and valeraldehyde , neutral odor components mainly composed of aldehydes such as propionaldehyde, acidic odor components mainly composed of lower fatty acids such as formic acid, acetic acid, propionic acid and valeric acid, toluene, xylene, butanol, methyl isobutyl ketone) Smells such as smoke, nonenal, pollen, and viruses are adsorbed on the coating layer of activated carbon powder formed on the wall surface of the air passage. Odorless and clean air from which odorous components, tobacco odor, nonenal odor, pollen, and viruses are removed by activated carbon powder flows from the rear surface of the flexible polyurethane foam toward the rear guard 13 of the commercial fan 11, and flows to the rear guard 13. The air flows from 13 toward the blades 18 and is blown to the front of the front guard 12 of the commercial fan 11 .
