The air blow rotator 15 is formed by external fitting.

That is, the mounting frame frame 21 has frame sides 21b, 21b ... Which are continuous at equal intervals in the longitudinal direction between both ends 21a, 21a forming a tubular shaft portion, and the frame sides 21b, 21b. A cylindrical cage portion 21d consisting of a frame periphery 21c continuous in the outer peripheral direction between them is integrally formed, and the rubber roller 17 is attached to one end portion 21a.

Become.

Here, the clean air discharged to the rotary flows Z, Z of the blower rotating bodies 15, 15 efficiently increases the blown air force synergistically at the confluence of the common blower path B. Is blown. Therefore, the clean air can quickly spread to the room where the rotary air cleaning device 1 is placed, and a comfortable and clean room atmosphere can be created.

In the above-described embodiment, the activated carbon layer 22 having a configuration in which granular activated carbon is compression-molded into a cylindrical shape to be solidified while maintaining air permeability is shown. However, as shown in FIGS. 5 and 6, The forming frame 31 is formed into a cylindrical basket shape by frame sides 31a, 31a ... Which are continuous at equal intervals in the longitudinal direction, and a frame periphery 31b which is continuous in the circumferential direction between the frame sides 31a.

Configuration for sealing the edge 31d In that case, the intake air is evenly contacted with the activated carbon flowing in the enclosure 34, and the cleaning and deodorizing action of the activated carbon can be further enhanced in combination with the filter function of the nonwoven fabric. The replacement can be easily performed only by replacing the enclosure 34.

Further, the opening surfaces 36, 36 ... Partitioned by the frame side 31a and the frame periphery 31b of the forming frame 31 and the outer peripheral surface of the inner cylinder 32 having the same structure as the forming frame 31 have fine air-permeable features.

A corona discharge action is generated between the electrodes 31 and 32 by an applied voltage from a high voltage generation circuit 33 installed below the partition plate 29 in parallel with each other, and a space region containing a large amount of negative ions is generated. The negative ion generating mechanism 34 for generating is provided, and the fragrance 35 formed by solidifying the volatile fragrance is further placed in the common air passage B and between the electrodes 31 and 32 so that the transparent surface plate 3 If attached to the inner surface, when the clean air in the common air passage B is discharged to the outside of the machine through the plain surface plate 3, the negative ions generated between the negative electrode 31 and the ground electrode 32 and the air blowing action are generated. The fragrance volatilized from the fragrance 35 is added to the clean air. As it is contained, the burning smoke of cigarettes in the clean air is adsorbed by the negative ions to be neutralized, and in the room where the rotary air cleaning device 1 is installed, fresh clean air containing an appropriate amount of aroma is provided. Being released, it becomes possible to create a pleasant atmosphere.

[Effect of the invention]

 In short, the present invention rotatably supports both end portions in the longitudinal direction of a cylindrical basket-shaped mounting frame, and attaches / detaches an activated carbon layer having a certain thickness having air permeability to the peripheral surface area of the mounting frame. A cylinder, which is freely circumscribed and has radial blades continuous in the longitudinal direction on the outer peripheral surface, and a plurality of through holes formed in the peripheral surface, is integrally fitted to the peripheral area of the activated carbon layer. To form a blower rotor, and to discharge polluted air that has flowed in from both ends of the mounting frame frame that is rotationally driven via a power source, from the outer peripheral surface of the blower rotor through the activated carbon layer. Since it is configured, the odor contained in cigarettes and human waste can be efficiently adsorbed and removed from the polluted air sucked from both ends of the mounting frame by simply rotating and driving the rotating blasting body. Emitted from the outer peripheral surface of Since the clean air to be blown is continuously blown to the outside by the rotating blades of the blower rotating body that is rotating, it is possible to reliably clean and release polluted air while configuring the blower rotating body compact. it can. In addition, a breathable activated carbon layer of a fixed thickness is interposed between the peripheral surface area of the rotatable mounting frame frame in the form of a cylindrical basket and the cylinder containing the mounting frame frame in a detachable manner. In addition, on the outer peripheral surface of the cylinder having a plurality of through holes formed therein, rotating blades continuous in the longitudinal direction are obliquely provided in a radial pattern to form a blower rotating body, and the blower rotating body is separated in vertically opposed positions. When the air blowers are rotated in different rotation directions with the mounting frame as the center of rotation, the air that flows in from both ends of each mounting frame and passes through the activated carbon layer is blown by each fan. Since the air is emitted from the outer peripheral surface of the body toward the common air passage formed between the blast rotors, the contaminated air sucked from both ends of the mounting frame can be simply driven by rotating the blast rotor. In contrast to that It is possible to efficiently adsorb and remove odors and human vibrations, and clean air released from the outer peripheral surface of the air blower rotor is merged in a common air duct to synergistically increase the air blow force. Since clean air can be efficiently distributed in a room equipped with a rotary air purifier, it is compact, yet it is possible to maintain sufficient ventilation and quickly create a comfortable indoor atmosphere. . Further, the activated carbon layer is formed by compression-molding granular activated carbon to be solidified into a cylindrical shape that can be integrated or divided, and a plurality of through holes are formed from the inner wall in the longitudinal direction to the outer peripheral wall of the activated carbon layer. Since it is possible to improve the efficiency of air intake by the blasting rotor, it is possible to easily replace the activated carbon layer whose adsorption and removal function has deteriorated with time without any troublesome work, and it is always the best option. The air cleaning operation can be secured. In addition, for the activated carbon layer, a bag-like enclosure having air permeability is loaded in a cylindrical cage-shaped forming frame that is externally fitted to the mounting frame, and the enclosure is filled with the required amount of granular activated carbon. Since it is configured as described above, the intake air is evenly contacted with the activated carbon flowing in the inclusion body, which can improve the air permeability and the cleaning and deodorizing effects. And so on, which have extremely useful practical effects.
