[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a filter device for purifying cooling and heating air or conditioned air blown out from a ceiling by a duct.

[0002]

[Prior art]

 Conventionally, the air blown out from this type of ceiling often needs to be further purified and blown off in a food factory or the like, and also needs to be finely blown. The conventional blow-off air purifying filter device has disadvantages in that the device is expensive and replacement or repair of the filter is troublesome.

A filter 20 made of a non-woven fabric in the form of a tray and externally fitted to the rectangular frame 10 and a filter forming frame 30 described later, and a filter forming device for forming the filter 20 into a substantially rectangular shape when blowing air. A frame 30 attached to the rectangular frame 10 and a filter 20 temporarily fixed to the rectangular frame 10; This is a blown air cleaning filter device which is mounted under a ceiling and has a metal band 40 which presses and tightens each side surface 11 of the rectangular frame 10 from the outside.

In the present invention, as shown in FIG. 8, the metal band 40 has a hook 41 fixed at one end, an elastic loop 42 at the other end, and a rotating loop 42 provided on the other end. It comprises a lever 43 to be supported, a rotating shaft 44 of the lever 43, and a support 45 that supports the rotating shaft 44 and is fixed to the other end. In the present invention, the metal band 40 is pressed against each side surface 11 of the rectangular frame 10 via the filter 20 and tightened to the rectangular frame 10. Therefore, a tightening method as shown in FIGS. Done. FIG. 4 shows the use of a band 40 composed of bands 401, 402, 403, 404 and 405 connected in a braille shape, and as shown in FIG. The band portions 401, 402, 403, 404, and 405 are pressed from above to tighten the rectangular frame 10. FIG. 5 shows the use of two U-shaped bands 40B1, 40B2 to press the band portions 401B1, 402B1, 403B1 and 401B2, 402B2, 403B2 to tighten the rectangular frame 10. In FIG. 6, two L-shaped bands 40C1 and 40C2 are used to press the respective band portions 401C1, 402C1, 401C2 and 402C2 to tighten the rectangular frame 10. FIG. 7 shows the use of linear bands 40D1, 40D2, 40D3, and 40D4 to press the respective band portions 401D1, 401D2, 401D3, and 401D4 to tighten the rectangular frame 10. In the present invention, in addition to the method of tightening the band with respect to the rectangular frame 10 shown in FIGS. 4, 5, 6, and 7, a combination thereof is appropriately performed according to the size of the rectangular frame 10.

[Embodiment of the invention]

 An embodiment of the present invention is shown in FIGS. The filter device for purifying blow-off air mounted under the ceiling according to the embodiment of the present invention includes a rectangular frame 10, a filter 20, a filter forming frame 30, and a metal band 40. As shown in FIG. 2, the rectangular frame 10 is formed by connecting a flange 12 to a short rectangular tube 11, 11, 11, 11 having a rectangular cross section. Attached to A hook tape 111 is attached to each side surface 11 of the rectangular frame 10. As shown in FIG. 3, the filter 20 is made of a nonwoven fabric sewn in a square tray shape, and the trade name "Tremicron E" manufactured by Toray Industries, Inc. is used as the nonwoven fabric for the filter. Further, the filter 20 is provided with a loop tape 221 which is fitted to the outside of the rectangular frame and is joined to the hook tape 111 attached to each side surface 11 thereof. The filter forming frame 30 is a frame for maintaining the filter 20 in a square tray shape at the time of blowing air, and is formed by a metal rod 31 as shown in FIG. 2 and attached to the square frame 10 so that the filter 20 is externally fitted. Is done. As shown in FIGS. 1, 3 and 4, the metal band 40 is formed so that it can be pressed against the rectangular frame 10 from above the filter 20 and tightened. Therefore, when the filter device of the present invention is mounted under the ceiling having the air blowing duct, first, the rectangular frame 10 and the forming frame 30 combined therewith are mounted on the lower surface of the ceiling, and then the loop tape 221 of the filter 20 is mounted. Alternatively, after temporarily attaching the hook tape to the hook tape 111 or the loop tape of the square frame 10, the metal band 40 may be tightened to the square frame 10 from above the filter 20, and the attachment or replacement of the filter 20 is easily and quickly. It can be carried out.

[0007]

[Effect of the invention]

 According to the present invention, it is possible to clean and blow down the air blown from below the ceiling by installing a simple device, and to install or replace the filter quickly and easily. Also, the device and the filter of the present invention can be manufactured at low cost, so that their practical value is great.
