In the deodorizer for a fan in the range of 20 to 40 cm / sec in the plane of soft polyurethane foam, since the surface area of the flexible polyurethane foam is in the above range, the deodorization filter does not become resistance to air flowing into the fan, Air can be smoothly introduced into the blades of the fan, and clean air having the odor component, the smell of tobacco, and the smell of nitrogen can be smoothly blown to the front of the fan by the deodorizing filter. In addition, since the air introduced into the fan does not pass through the ventilation ducts of the flexible polyurethane foam in an instant, the air can be sufficiently brought into contact with the wall surface of the ventilator of the polyurethane foam, and the odor components, It is possible to sufficiently adsorb the nitrogen gas odor to the activated carbon coated on the polyurethane foam or the activated carbon mixed in the polyurethane foam.

A deodorant for an electric fan, which is an air filter having a function of collecting net or fine impurities, has a predetermined mesh number. When air is introduced into a fan, the air flows through the net, And the odor components, tobacco odor and nitrogen odor contained in the air can be reliably adsorbed on the activated carbon coated on the polyurethane foam or the activated carbon mixed in the polyurethane foam, , The dust is trapped in the net, so that clean air, which has removed the dust together with the odor contained in the air, can be blown in front of the fan. When the package sheet is made of a filter, impurities such as fine dust, pollen, PM 2.5, and germs contained in air are trapped in the filter when the air passes through the filter, and the odor contained in the air and the impurities Air can be blown in front of the fan. In addition, since the impurities do not adhere to the ventilating duct of the flexible polyurethane foam, deterioration of the deodorizing function due to attachment of the impurities to the ventilating duct of the polyurethane foam can be prevented.

The deodorizer for an electric fan, which is made of an air filter having a predetermined number of meshes, a net positioned on one of the front and rear surfaces and a function of collecting fine impurities and located on the other of the front and rear surfaces, When the net is located on the front and the filter is located on the rear side, impurities such as fine dust, pollen, PM 2.5, and germs contained in the air are trapped in the filter, and the odor contained in the air and the clean air Can be blown to the front of the electric fan and deterioration of the deodorizing function due to adherence of the impurities to the ventilating duct of the flexible polyurethane foam can be prevented and it is possible to prevent deterioration of the deodorizing function of the impregnated activated carbon or polyurethane foam coated on the polyurethane foam It can be adsorbed firmly on activated carbon.

The deodorizer 10A for a fan has a deodorization filter 13 having a front surface 11 and a rear surface 12 and having a predetermined area for removing the odor contained in the air and a support frame 14 . The deodorization filter 13 is connected to the upper area 15 of the predetermined area and the predetermined thickness and the first side area 16 of the predetermined area and the predetermined thickness to which the upper area 15 is connected and the upper area 15 And a second side area 17 having a predetermined area and a predetermined thickness. The deodorization filter 13 (the upper area 15 and the first and second lateral areas 16 and 17) has an outer periphery 18 extending in an annular shape (drawing a circular arc) And has an inner periphery 19 which is connected to the outer periphery 18 and separates from the outer periphery 18 radially inward.

Examples of the deodorization filter 13 include a flexible polyurethane foam 20 having open cells and an activated carbon powder (not shown) fixed to the wall surface 21 of the polyurethane foam 20 through a predetermined binder (adhesive) And a breathable net 22 (packaging sheet) of a predetermined mesh number for covering (covering) the entire polyurethane foam 20. The flexible polyurethane foam 20 has a predetermined thickness, is flexible, and is elastically deformable.

In order to apply the activated carbon powder to the wall surface 21 of the flexible polyurethane foam 20, the mixed paint of the activated carbon powder and the binder is sprayed onto the polyurethane foam 20, and the mixed paint is dried, or , A mixed paint of activated carbon powder and a binder may be subjected to hot-dip galvanization of a polyurethane foam to dry the mixed paint. In the flexible polyurethane foam 20 coated with activated carbon powder, activated carbon powder is laminated on the wall surface 21 of the polyurethane foam 20, and a coating layer of activated carbon is formed on the wall surface 21 of the polyurethane foam 20 have.

As another example of the deodorization filter 13, there are a flexible polyurethane foam 20 having open cells in which a foam raw material in which activated carbon powder is mixed is foamed, a flexible polyurethane foam 20 having a predetermined mesh number of breathable Net 22 (package sheet). Activated carbon is exposed on the wall surface 21 of the polyurethane foam 20 in the flexible polyurethane foam 20 in which the foam raw material containing activated carbon powder is foamed. The flexible polyurethane foam 20 incorporating the activated carbon powder has a predetermined thickness, is flexible, and is elastically deformable.

As the flexible polyurethane foam 20 in which the activated carbon powder is mixed, a polyether foam based on a tolylene diisocyanate and a polyether polyol or a polyester based on a tolylene diisocyanate and a branched polyester polyol The system is being used. The polyurethane foam 20 is foamed by adding water and an auxiliary foaming agent to the foam raw material, adding additives used for adjusting the diameter of the foam.

The 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 function of adsorbing radioactive substances such as iodine and gaseous cesium). The activated carbon powder is made by pulverizing activated carbon and has an average particle diameter of 5 to 10 탆. Activated carbon processed with activated carbon powder is made from coconut shell, sawdust, hard wood chips, charcoal, chrysotile, etc. as raw materials. The mixing ratio of the activated carbon powder to the foam raw material is 80 to 180% by weight of the activated carbon powder, preferably 100 to 150% by weight of the activated carbon powder, relative to 100% by weight of the foam raw material.

The flexible polyurethane foam 20 has a plurality of ventilating passages 23 existing between the front and rear faces 11 and 12 of the deodorization filter 13 and a plurality of ventilating passages 23 connected to the ventilating passages 23, (See Fig. 6). These ventilating passages 23 are formed inside the polyurethane foam 20 surrounded by the wall surface 21 of the polyurethane foam 20.

The ventilation passage 23 is extended between the front face 11 and the rear face 12 of the deodorization filter 13 while being irregularly curved in the thickness direction of the polyurethane foam 20, 13 between the outer periphery 18 and the inner periphery 19 of the polyurethane foam 20 in the radial direction. These ventilation passages 23, which are adjacent to each other in the radial direction and extend in the thickness direction, are partially connected in the radial direction, and one ventilation passage 23 and the other ventilation passage 23 communicate with each other. These ventilation paths 23, which are adjacent to each other in the thickness direction and extend in the radial direction, are partly connected in the thickness direction, and one ventilation passage 23 and the other ventilation passage 23 communicate with each other.

The opening area of the air passage 23 is not uniform toward the thickness direction but varies irregularly toward the thickness direction and is irregular toward the radial direction and irregularly changes toward the radial direction. The air passage 23 is irregularly opened in the thickness direction and in the radial direction while its opening area becomes larger or smaller. Also, the ventilation holes 24 connected to the ventilation passages 23 are not uniform in area and have different areas.

The flexible polyurethane foam 20 has a thickness of 5 to 20 mm, preferably 10 to 15 mm. If the thickness of the polyurethane foam 20 is less than 5 mm, the specific surface area of the wall surface 21 of the polyurethane foam 20 can not be increased, and the polyurethane foam 20 coated with the activated carbon powder or activated carbon powder The odor adsorption function of the polyurethane foam 20 can not be improved.

The polyurethane foam 20 does not become the resistance of the air flowing into the blades 41 of the fan units 38A and 38B and the air can smoothly flow into the blades 41 of the fan units 38A and 38B.

The flexible polyurethane foam 20 has a mass of 40 to 80 g. The deodorization filter 13 can be constructed so that the deodorizing filter 10 can be easily attached to the fan blades 38A and 38B because the mass of the polyurethane foam 20 is within the above range and the deodorization filter 13 can be made light in weight. So that the deodorizer 10A for the fan can be easily detached from the fan blades 38A and 38B and the installation work or replacement operation for the fans 38A and 38B of the deodorizer 10A for the fan can be performed And it is also possible to prevent unexpected detachment of the deodorizer 10A for the fan from the fans 38A and 38B.

The second side area 17 extends downward from the upper area 15 toward the base 44 of the fan 38B and is located on the side of the other side 46 of the motor case 40, (46) of the other side (40).

The size (diameter) of the deodorizer 10A for the fan mounted on the fan 38B is larger than the size of the deodorizer 10A for the fan mounted on the fan 38A. In the deodorizer 10A for a fan, when the deodorizer 10A is mounted on the fan 38B, the outer periphery 18 of the deodorization filter 13 and the first and second lateral areas 16, 17 The second outer peripheral frame 28 of the outer frame 25 is positioned on the outer peripheral edge 48 (the second outer peripheral frame 29 of the rear guard 39) of the rear guard 39 and the wings 41 And the radial direction distal end portion 47 of the base portion.
