This invention eliminates too cold air and promotes air agitation and diffusion.

Description

  The present invention relates to a stirring fan mounted on a ceiling duct and a duct outlet of a spot cooler.

  This type of ceiling duct or spot cooler blows (injects) cold air or the like toward a local area. Thus, since it blows toward one place, there exists a bad effect and the solution is desired. Moreover, since it is inconvenient and useless, the solution is a situation demanded.

  As an adverse effect, since the air blows directly, overcooling becomes a problem. In particular, in the case of girls, there are increasing cases of adverse effects on the body, and countermeasures are urgently needed. However, in reality, no means are taken.

  In addition, as an example of inconvenience and waste improvement, for example, there are inventions disclosed in Japanese Patent Laid-Open No. 10-61975 or Japanese Patent Laid-Open No. 2004-183927 (refer to Document (1) and Document (2)). ). The present invention has a structure in which a plurality of air outlets are provided, and air from the plurality of air outlets is controlled using a control device such as a sensor and a computer. Therefore, the worker blows air from the corresponding outlet as the work location moves. Although the present invention is effective, it is the same as in the prior art that the air is blown directly from one air outlet, and the above-mentioned adverse effects are not solved.

  Moreover, as invention regarding the fan provided in the blower outlet of the branch duct of an air conditioner, there exists invention disclosed by Unexamined-Japanese-Patent No. 2010-151418, for example (referred to as literature (3)). The present invention has a structure in which a fan is provided on a grille provided on a ceiling surface so as to be movable up and down so that the amount of outside air sucked into the grill can be adjusted and the amount of air blown from the air outlet of the grill can also be adjusted. However, blowing air directly from one outlet is the same as in the past, and does not eliminate the above-mentioned adverse effects.

  The agitating fan A includes a ring body 1 made of a band material (including a structure in which a half semi-curved curved band body is formed in an annular shape), and a U-shaped attachment body 2 provided on the ring body 1 so as to be slidable. The flexible plastic fan 3 provided on the mounting body 2 is a main component. The stirring fan A is detachably attached to the air outlet D1 of the ceiling duct B of FIG. 1-1 or the flexible duct D (duct D) of the spot cooler C of FIG. 1-2. And preferably, it attaches to each main outlet B1 of the ceiling duct B shown in FIGS. 1-1, or each blower outlet D1 of the duct D branched from the terminal box which is not illustrated. Alternatively, it is also useful to detachably attach each outlet D1 of the duct D of the spot cooler C of FIG.

  The ring body 1 has a plurality of brackets 5 (stoppers) each having a substantially inverted L shape mounted on the air outlet D1 (for example, preventing depression into the duct D). (Hereinafter described as one) is provided with an inverted L-shaped base end 5 a on the inner surface 1 a of the ring body 1, and a bent piece 5 b that protrudes toward the center of the ring body 1. A plurality of the brackets 5 are provided on the inner surface 1a or the outer surface 1b (not shown) of the ring body 1 or the like. A first screw hole 6 is formed at a base end 5a of the bracket 5 and an attachment portion of the ring body 1 provided with the base end 5a. A first set screw 7 is provided in the first screw hole 6 by screwing, fitting, clamping, etc., and a tip 7a of the first set screw 7 is provided on the outer surface D11 of the blowout port D1. (Pressed or pressed). In this way, the ring body 1 is attached to the outlet D1. In addition, in the method of pressure bonding to the outer surface D11 of the first set screw 7, the ring body 1 is securely and stably attached to the air outlet D1. Further, the bent piece 5b of the bracket 5 is structured to be locked to the end face D111 of the air outlet D1, and does not sink into the inner side D1111 of the air outlet D1 (duct D). Further, by making it possible to correspond to the diameter of the air outlet D1 corresponding to the length dimension of the bent piece 5b, for example, the effectiveness or replacement to the diameter of the air outlet D1, its deformation, or an irregular shape, etc. Contributes to versatility such as use and storage. In addition, although not shown in figure, as stoppers other than the bracket 5, other shapes, such as an inverted U-shape, a key shape, and a hex shape, are possible, for example.

  A pair of rails 8 and 8 are provided in the longitudinal direction of the outer surface 1b or the inner surface 1a (not shown) of the ring body 1 as a pair in the opposite direction (typically 8). An example will explain on the other hand). The leg portions 10a and 10a of the U-shaped mounting body 10 are inserted into the pair of rails 8, respectively. Long holes 10b and 10b are formed in the leg portion 10a in the vertical direction. In addition, the attachment body 10 is provided with a flange portion 10c provided so as to extend to both the leg portions 10a. In the embodiment, both the leg portions 10a and the flange portion 10c are integrally formed. A screw shaft 11 is erected on the flange portion 10 c of the attachment body 10. A tube 15 provided on the hub 3 a of the fan 3 is inserted into the screw shaft 11. After inserting the hub portion 3 a, the nut 12 is screwed into the screw portion 11 a and the fan 3 is attached to the screw shaft 11. The fan 3 uses the tube 15 loosely fitted to the screw shaft 11 and can be rotated lightly, without noise, and smoothly.

  An example of attaching the attachment body 10 to the ring body 1 will be described. A leg 10a is inserted into a set of rails 8 of the ring body 1, and a second set screw inserted into the elongated hole 10b of the leg part 10a. 13 and 13 are provided in the second screw holes 1c and 1c provided in the ring body 1 by screwing, fitting, clamping, etc. (and the second set screws 13 and 13 are provided in the third part of the mounting body 10). It is also possible to provide a second screw hole 1c, 1c and a third screw hole, both of which provide stability and a strong attachment body 10. Can be installed). In this manner, the attachment body 10 is attached to the ring body 1 so as to be adjustable to a desired height. In addition, when the crimping surface of the second set screw 7 is crimped to the outside of the leg portion 10a, the attachment body 10 is securely and stably attached to the ring body 1. In this way, the second set screw 13 is screwed back or screwed in and the sliding of the attachment body 10 is used to fix the second set screw 13 to a predetermined height of the air outlet D1. The sliding of the mounting body 10 is in the longitudinal direction X shown in FIG. 1 or FIG. Through this sliding, the fan 3 is contacted and separated from the opening (end surface D111) of the air outlet D1, and the flow of air from the air outlet D11 and the stirring direction (diffusion direction), the air volume, the air speed, etc. In addition to controlling, the agitation of the factory space, the air volume, the wind speed, etc.

  Hereinafter, the installation and use of the stirring fan A will be described. The ring body 1 is fitted to the outlet D1 of the duct D in each example, and the bent piece 5b of the bracket 5 is locked to the end face D111. With this locking, the stirring fan A is prevented from sinking into the duct B and temporarily fixed to the end surface D111. Thereafter, the plurality of first set screws 7 are screwed in, and the tip 7a of the first set screw 7 is crimped to the outer surface D11 of the duct D, whereby the mounting and fixing of the stirring fan A is completed. In this state, when the position of the fan 3 is changed, the second set screw 13 is unscrewed, and the tightening of the ring body 1 and the attachment body 10 is released. Using this release, the attachment body 10 is moved in the longitudinal direction X, and when it reaches a predetermined position, the screwed second set screw 13 is screwed. By fixing the moved attachment body 10 to the ring body 1 by this screwing, the movement and fixation are completed.
