It is arranged. An operation box 25 is provided on the front surface of the casing 10.

  Next, the effect | action of the deodorizing apparatus 1 which has the above structure is demonstrated based on FIG.

  For example, when changing diapers in elderly care or inpatient care, as shown in FIG. 4, the deodorizing device 1 is placed on a carriage 26 and transported to the vicinity of a bed (not shown). The apparatus main body is rotated and fixed horizontally so that the opening 5a can aim at the odor source 27, and the elevation angle mechanism 13 rotates the outer rotation hood 5 up and down to adjust the elevation angle. In the present embodiment, the odor source 27 is at a height of about 500 mm from the floor surface, and the reach distance of the odor from the odor source 27 is about 1 m. 5 front end openings 5 a are installed at a distance of about 1 m from the odor source 27.

  After the deodorizing apparatus 1 is installed as described above, when the plasma creeping electrode 19, the ultraviolet lamp 20, the swirling fan 15 and the suction fan 17 are driven by the switch operation of the operation box 25, the air discharged from each swirling fan 15. Is guided in the tangential direction into the swirl flow path 7 in the outer swirl hood 5 while being guided by the duct 16, whereby an outer swirl flow is formed in the swirl flow path 7. The outer swirl flows forward while increasing its diameter toward the odor source 27 as indicated by an arrow in FIG. 4 and gently wraps the odor source 27 with air to prevent odor diffusion. In the present embodiment, the odor is wrapped in the range of the maximum diameter of 1 m by the outer swirling flow.

  By the way, in the present embodiment, as described above, the opening end surface 5a of the partition wall 6 is disposed inward by Δ shown in FIG. 1 with respect to the opening end surface 5a of the outer swirl hood 5, so that diffusion of the outer swirl flow to the periphery is prevented.

  Further, a part of the outer swirl flow of the swirl flow path 7 formed in the outer swirl hood 5 is tangent along the current plate 9 into the partition wall 6 from the outlets 8 formed at three places on the entire periphery of the partition wall 6. It is ejected in the direction to form an inner swirling flow in the partition wall 6. The artificial tornado induced by the inner swirling flow adds centripetal force and suction force to the centripetal force and suction force by the outer swirl flow. For this reason, the centripetal force and the suction force are increased, and the odor reaches the outer swivel hood 5 by the high centripetal force and the suction force, and is sucked into the center of the outer swirl hood 5 with the suction action by the suction fan 17 and collected.

Deodorizing treatment is efficiently carried out by the adsorption action of activated species and activated carbon when decomposed at 22. The odorless air is discharged from the suction fan 17 and is discharged to the outside through a hose not shown.

  As described above, in the present embodiment, since the inner and outer double swirl flows of the outer swirl flow and the inner swirl flow are generated in the air collecting device 1, the odor source 27 is widely and gently wrapped in the outer swirl flow. Thus, while preventing diffusion of the odor around, the encapsulated odor can be efficiently and quickly sucked and collected by the strong centripetal force and suction force enhanced by the internal swirl flow. In this case, the air ejected from the air outlet 8 formed in the partition wall 6 is guided by the rectifying plate 9 and flows tangentially into the partition wall 6, so that the centripetal force and suction force by the inner swirl flow are enhanced, and the odor Is collected more efficiently and quickly.

  Further, since the air discharged from the plurality of swirling air fans 15 as the gas discharging means is guided by the duct 16 and blown into the swirling flow path 7 in the tangential direction, the outer swirling hood 5 and the partition wall 6 define the air. A strong outer swirling flow can be generated in the swirling flow path 7.

Therefore, the deodorizing device 1 is reduced in size and size, and the space saving associated therewith is realized. can do.

  Furthermore, in the deodorizing apparatus 1 according to the present embodiment, the elevation angle of the outer swirl hood 5 of the air collecting device 2 can be adjusted by the elevation angle mechanism 13, so that the opening end surface 5 a of the outer swirl hood 5 is used as the odor source 27. It can always be directed accurately, and the odor can be efficiently collected from the odor source 27.

  Moreover, since the main body of the deodorizing apparatus 1 can be swiveled horizontally with respect to the fixed plate 4, it is possible to deal with a plurality of odor sources on the spot without moving the deodorizing apparatus 1, resulting in work efficiency. Can be increased.

  In addition, if the air deodorized in the deodorizing unit 3 is returned from the suction fan 17 to the swirling fan 15, and this air is used for generating the inner and outer double swirling flows in the air collecting device 2, the deodorized air is used. Since there is no need to discharge to the outside, no exhaust equipment is required, and the deodorizing apparatus 1 can be further reduced in size and size.

  In this embodiment, the air outlets 8 are formed at three locations on the entire periphery of the partition wall 6 and the same number of the three swirling fans 15 and the ducts 16 are provided. However, these numbers may be three or more. 4 or more may be sufficient.
