  The electric fan 10A has a turning mechanism that turns the motor case 14 (front and rear guards 17, 18 and blades 16) in the vertical direction. In the electric fan 10A, the motor case 14 (the front and rear guards 17, 18 and the blades 16) can be turned 90 degrees upward and downward from the state of FIG. 1 in which the front and rear guards 17 and 18 and the blades 16 face forward. The motor case 14 can be turned 90 degrees downward in the vertical direction from the state in which the guards 17 and 18 and the blades 16 face upward (see FIG. 9).

  The deodorizing tool 19A is detachably attached between the blades 16 and the rear guard 18 and immediately before the guard 18, and removes odors (odor components, tobacco odor, nonenal odor) contained in the air. The deodorizing tool 19A includes a donut-shaped front surface 21 having a predetermined area, a donut-shaped rear surface 22 having a predetermined area, an inner peripheral edge 23 extending in the circumferential direction, an outer peripheral edge 24 extending in the circumferential direction, and an inner peripheral edge 23. And an enclosed circular central opening 25.

  The deodorizing tool 19A includes a soft polyurethane foam 26 having open cells, activated carbon powder (not shown) that adsorbs odors contained in air, a support frame 27 that supports the polyurethane foam 26, and a net 28 having a plurality of meshes.

In addition, the outer peripheral edge part 24 may be located in the inner area M1 of the inner area M1 and the outer area M2 of the blade 16 divided by the first dividing line L1.

  The flexible polyurethane foam 26 is molded into a donut shape. As shown in FIG. 2, the polyurethane foam 26 has a plurality of ventilation paths 29 existing between the front and rear surfaces 21 and 22 and a plurality of ventilation holes 30 connected to the ventilation paths 29 and opening to the front and rear surfaces 21 and 22. And has a predetermined thickness and flexibility. These air passages 29 are surrounded by the wall surface 31 of the polyurethane foam 26 and defined inside the polyurethane foam 26.

  The activated carbon powder may be fixed to the wall surface 31 of the flexible polyurethane foam 26 with a predetermined binder (adhesive) or may be kneaded into the polyurethane foam 26. In order to fix the activated carbon powder to the wall surface 31 of the polyurethane foam 26, the mixed paint of the activated carbon powder and the binder is spray-coated on the polyurethane foam 26 and the mixed paint is dried, or the mixed paint of the activated carbon powder and the binder. In some cases, the polyurethane foam 26 is applied to the surface and the mixed paint is dried.

  In the polyurethane foam 26 to which the activated carbon powder is applied (fixed), the activated carbon powder is laminated on the wall surface 31, and the activated carbon coating layer is formed on the wall surface 31 that defines the air passage 29. The polyurethane foam 26 in which the activated carbon powder is kneaded is made by foaming a foam material mixed with the activated carbon powder. In the polyurethane foam 26 in which the foam raw material mixed with the activated carbon powder is foamed, the activated carbon is exposed on the wall surface 31 that defines the air passage 29.

  For the polyurethane foam 26, a polyether foam made from tolylene diisocyanate and polyether polyol or the like, or a polyester foam made from tolylene diisocyanate and a branched polyester polyol or the like is used. The polyurethane foam 26 is foamed with water and a foaming aid by adding an additive used for adjusting the cell diameter to the foam raw material.

The activated carbon powder has a specific surface area of about 300 to 5000 m ² / g and has a high odor adsorbing function (including a function of adsorbing radioactive substances such as iodine and gaseous cesium). The activated carbon powder is made by finely pulverizing activated carbon and has an average particle size in the range of 5 to 10 μm. Activated carbon processed into activated carbon powder is made from coconut shells, sawdust, hard wood chips, charcoal, grass charcoal and the like. The mixing ratio of the activated carbon powder to the foam raw material is 80 to 180% by weight of the activated carbon powder with respect to 100% by weight of the foam raw material, and preferably 100 to 150% by weight of the activated carbon powder with respect to 100% by weight of the foam raw material.

  The air passage 29 extends between the front surface 21 and the rear surface 22 while being irregularly bent in the thickness direction of the polyurethane foam 29, and the diameter of the polyurethane foam 29 between the inner peripheral edge portion 23 and the outer peripheral edge portion 24. Extends in an irregular direction. The ventilation paths 29 that are bent in the thickness direction adjacent to the radial direction are partially connected in the radial direction, and the one ventilation path 29 and the other ventilation path 29 communicate with each other. The air passages 29 extending in the radial direction adjacent to the thickness direction are partially connected in the thickness direction, and one air passage 29 and the other air passage 29 communicate with each other.

  The opening areas of the air passages 29 are not uniform in the thickness direction, vary irregularly in the thickness direction, are not uniform in the radial direction, and are irregular in the radial direction. Has changed. The air passages 29 are irregularly opened in the thickness direction and the radial direction while the opening area is increased or decreased. Moreover, those vent holes 30 connected to the vent passage 29 are not uniform in area and differ in area.

  The polyurethane foam 26 has a thickness dimension in the range of 3 to 10 mm, preferably in the range of 4 to 6 mm. When the thickness dimension of the polyurethane foam 26 is less than 3 mm, the specific surface area of the wall surface 31 of the polyurethane foam 26 cannot be increased, and the odor adsorbing function of the polyurethane foam 26 coated with activated carbon powder or the polyurethane foam 26 mixed with activated carbon powder can be obtained. It cannot be improved. When the thickness dimension of the polyurethane foam 26 exceeds 10 mm, the air resistance of the polyurethane foam 26 is large, the deodorizing tool 19A becomes the resistance of the air entering the blades 16 of the electric fan 10A, and air can smoothly flow into the blades 16. Can not.

  In the deodorizing tool 19A, since the thickness dimension of the polyurethane foam 26 making it is in the above range, the specific surface area of the wall surface 31 of the polyurethane foam 26 can be increased, and the polyurethane foam 26 coated with the activated carbon powder or the activated carbon powder is mixed. The odor adsorption function of the polyurethane foam 26 can be improved, and the activated carbon applied to the polyurethane foam 26 and the activated carbon mixed in the polyurethane foam 26 with the odor component, tobacco odor, and noneal odor contained in the air entering the electric fan 10A. Can be adsorbed sufficiently. Further, the polyurethane foam 26 (deodorizing tool 19A) does not become the resistance of the air entering the blades 16, and the air can smoothly flow into the blades 16.

  The polyurethane foam 26 has a mass in the range of 30 to 60 g. In the deodorizing tool 19A, the mass of the polyurethane foam 26 is in the above-described range, and the deodorizing tool 19A can be reduced in weight. Therefore, the deodorizing tool 19A can be easily attached to the electric fan 10A, and the deodorizing tool 19A can be removed from the electric fan 10A.

If the surface speed of the polyurethane foam 26 is less than 20 cm / sec, the air cannot smoothly flow through the polyurethane foam 26, and the deodorizing tool 19 </ b> A becomes the resistance of the air that enters the blade 16, and the air is smoothly supplied to the blade 16. Can not flow into. When the surface speed of the polyurethane foam 26 exceeds 40 cm / sec, the air that has entered the electric fan 10 </ b> A quickly passes through the air passage 29 of the polyurethane foam 26, and the air cannot sufficiently contact the wall surface 31 of the air passage 29. The odor component, tobacco odor and nonenal odor contained in the air cannot be sufficiently adsorbed on the activated carbon applied to the polyurethane foam 26 or the activated carbon mixed in the polyurethane foam 26.

  In the deodorizing tool 19A, the surface speed of the polyurethane foam 26 is in the above range, so that the deodorizing tool 19A does not become the resistance of the air entering the blades 16, and the air can smoothly flow into the blades 16. Further, the air that has entered the electric fan 10A does not quickly pass through the air passage 29 of the polyurethane foam 26, and can sufficiently contact the air with the wall surface 31 of the air passage 29, so that odor components and tobacco odor contained in the air can be obtained. The nonnal odor can be sufficiently adsorbed on the activated carbon applied to the polyurethane foam 26 or the activated carbon mixed in the polyurethane foam 26.

Odorless and clean air from which fine impurities are removed by the filter 42 and odor components, cigarette odors, and nonenal odors are removed by the deodorizing tool 19F is blown from the front guard 17 to the front of the fans 10A to 10C.

  The fans 10A to 10D in which the deodorizing tools 19A and 19D are installed include the deodorizing tools 19A and 19D including the soft polyurethane foam 26 to which the activated carbon powder that adsorbs the odor components contained in the air is fixed and the polyurethane foam 26 in which the activated carbon powder is mixed. Since it is attached between the blade 16 and the rear guard 18, when the air that has entered the electric fans 10 </ b> A to 10 </ b> D flows through the air passage 29 of the polyurethane foam 26, the odor component, tobacco odor, and noneal contained in the air The odor can be adsorbed on the activated carbon, and the odor components, tobacco odor, and nonenal odor contained in the air passing through the fans 10A to 10D can be removed. The fans 10A to 10D in which the deodorizing tools 19A and 19D are installed can make clean air from which the odor components, cigarette odors, and nonenal odors contained in the air are removed by activated carbon. At the same time, odorless and clean air can be sent.

  The fans 10A to 10D in which the deodorizing tools 19B, 19C, 19E, and 19F are installed have the following effects in addition to the effects of the fans 10A to 10D in which the deodorizing tools 19A and 19D are installed. In the fans 10A to 10D in which the deodorizing tools 19B, 19C, 19E, and 19F are installed, when the air flows through the filter 42, impurities such as fine dust, pollen, and PM2.5 contained in the air are collected in the filter 42. In addition, odorless and clean air from which impurities are removed together with the odor contained in the air can be sent. Furthermore, since impurities do not adhere to the polyurethane foam 26, it is possible to prevent a decrease in the odor adsorbing function of the activated carbon due to the impurities adhering to the polyurethane foam 26, and the odor components, tobacco odors, and nonenal odors contained in the air. Can be reliably adsorbed on activated carbon.

  In the electric fans 10A to 10D, the flow velocity of the air entering the blades 16 from the rear guard 18 is slow, and the air slowly flows through the air passage 29 of the polyurethane foam 26. Therefore, the deodorizers 19A to 19F are connected to the blades 16 and the front guard 17. Compared with the case where it installs in between, the contact time with respect to activated carbon of air can be lengthened, and the smell contained in air can be made to adsorb | suck to activated carbon reliably. The fans 10A to 10D enter the fans 10A to 10D again after the indoor air flows through the air passage 29 of the polyurethane foam 26 during the operation, and the air repeats the air passage 29. Since it is circulated (circulated), the indoor air is gradually purified by the deodorizing tools 19A to 19F, and the deodorizing function can be sufficiently exhibited by operating the fans 10A to 10D for a long time. The odor can be surely removed.
