(Embodiment 1)
As shown in FIGS. 1-8, the stand 5 which supports the ventilation part 4 which consists of the blade | wing 1, the guard 2, and the electric motor 3 so that turning is possible downward via the rod 5a, and the electrical equipment part 6 built in the stand 5 are shown. A lid 7 that covers the upper side; and a ceiling mounting plate 11 that is detachably connected to a support fitting 8 that extends from the stand 5 and that is connected to a ceiling-mounted hanging bolt 9 via a nut 10. Is disposed in the stand 5 and provided in the storage portion 13 that can store the power cord 12 between the ceiling mounting plate 11, and a plurality of reinforcing ribs 14 are provided so that the hollow stand 5 is reinforced. The lid body 7 is inserted into a region surrounded by the wall portion 15 of the stand 5.

  In addition, a protective rib 16 that surrounds and protects the support fitting 8 is formed in the lid body 7, a cord lead-out hole 17 is formed in the wall portion 15 higher than the lid body 7 in the stand 5, and the ceiling mounting plate 11 is on the side opposite to the stand Furthermore, the stand 5 side is formed in a concave shape so as to swell.

  In addition, a suspension hole 18 is provided in the ceiling mounting plate 11 in order to connect to the suspension bolt 9 installed on the ceiling, a central suspension hole 19 in which the suspension hole 18 is provided at the center of the ceiling attachment plate 11, The left and right suspension holes 20 provided at left and right symmetrical positions are provided, and the left and right suspension holes 20 are long holes, and the hole pitch is set to 50 mm or less.

  Further, the cord 22 from the ceiling swirling fan 21 and the power cord 12 drawn from the ceiling are connected to the ceiling mounting plate 11, and temporarily supported so that the ceiling swirling fan 21 does not fall while the ceiling swirling fan 21 is attached to the ceiling. One of the possible wires 23 is attached to the ceiling mounting plate 11, the other is attached to the support bracket 8 provided on the ceiling swing fan 21, the temporary support means 24 is formed, and the claw 25 provided on the support bracket 8 is engaged. A hole 26 is provided in the ceiling mounting plate 11.

  In the above configuration, when the ceiling swirling fan 21 is attached to be suspended by using a single suspension bolt 9, the ceiling bolt 27 penetrates the ceiling plate 27 from the back of the ceiling and is exposed to the suspension bolt 9 exposed on the lower surface of the ceiling plate 27. The center suspension hole 19 of the mounting plate 11 is inserted and the power cord 12 on the back of the ceiling is pulled out through the ceiling mounting plate 11, and the nut 10 is screwed onto the suspension bolt 9 to attach the ceiling mounting plate 11 to the suspension bolt 9. The ceiling swivel fan 21 is temporarily supported on the ceiling mounting plate 11 via the mounting and temporary support means 24, and in the temporarily supported state, the power cord 12 drawn from the back of the ceiling and the cord lead hole 17 are drawn to the outside. The cord 22 of the ceiling swirling fan 21 that draws the cord 22 into the cord drawing hole 17 is connected.

  Then, an excessively drawn portion of the connected power cord 12 and cord 22 is stored in the storage portion 13 provided between the lid body 7 and the ceiling mounting plate 11, and the claw 25 of the ceiling swirl fan 21 is mounted on the ceiling. The ceiling revolving fan 21 is attached to the lower side of the ceiling plate 27 through the ceiling mounting plate 11 by engaging with the engagement hole 26 provided in the plate 11.

A lid 7 that covers the upper part of the electrical component 6 to be mounted, and a ceiling mounting plate 11 that is detachably connected to a support fitting 8 that extends from the stand 5 and that is coupled to a hanging bolt 9 installed on the ceiling. Since the power cord 12 can be stored between the body 7 and the ceiling mounting plate 11 inside the stand 5, the power cord 12 pulled out from the ceiling plate 27 and the cord 22 from the ceiling revolving fan 21 side are connected. The extra power cord 12 and the like can be stored in the storage section 13 provided between the lid 7 and the ceiling mounting plate 11, and compared with the case where the extra power cord 12 or the like is pushed into the back of the ceiling. Of the ceiling revolving fan 21 With work can be facilitated.

  Further, by inserting the lid body 7 into a region surrounded by the plurality of reinforcing ribs 14 formed to reinforce the hollow stand 5 and the reinforcing ribs 14 and the wall portion 15 of the stand 5, The strength of the stand 5 can be increased by protecting the storage portion 13 of the cord 22 and supporting the wall portion 15 of the stand 5.

  Further, by forming the protective rib 16 surrounding the support fitting 8 on the lid body 7, the edge of the support fitting 8 can protect the cord 22, and safety is improved, and the operation at the time of taking out and attaching is easy. Can be.

  Further, by forming the cord lead-out hole 17 in the wall portion 15 higher than the lid body 7 of the stand 5, the cord 22 pulled out from the lid body 7 is positioned above the lid body 7 fitted in the stand 5. When the cord is pulled out from the cord drawing hole 17 to the outside of the stand 5 and attached to the side of the ceiling, it is connected and attached to the power cord 12 as it is.

  When attaching directly to the ceiling, the cord 22 is pulled out into the stand 5 from the cord lead-out hole 17 of the wall portion 15 so that the cord 22 is not passed through the cord lead-out hole 17 and can be easily connected to the power cord 12. Therefore, the workability is good, and it can be made safe without adversely affecting the electrical component 6.

  Further, by making the stand 5 side concave so that the ceiling mounting plate 11 is inflated to the anti-stand side, the storage portion 13 of the cord 22 between the ceiling mounting plate 11 and the stand 5 can be made wider, and the ceiling mounting plate 11 The strength of can be increased.

  In addition, the ceiling mounting plate 11 is provided with a suspension hole 18 to be connected to the suspension bolt 9 installed on the ceiling, the suspension hole 18 is provided at the center of the ceiling attachment plate 11, and the left and right sides of the central suspension hole 19. By constituting with the left and right suspension holes 20 provided at symmetrical positions, when there is only one suspension bolt 9 suspended from the ceiling, the central suspension hole 19 of the ceiling mounting plate 11 is used, and the suspension bolt 9 is suspended from the ceiling. In the case where the number of the lowering bolts 9 is two, by using the left and right suspension holes 20, it is possible to cope with diversification of ceiling mounting and to cope with diversification of workability.

  Further, the left and right suspension holes 20 are long holes and the hole pitch is 50 mm or more, and the left and right suspension holes 20 are long holes, so that mounting displacement can be easily corrected and the left and right suspension holes 20 can be attached. By making the pitch of 50 mm or more, cracking of the concrete can be prevented when the anchor bolt is hit on the concrete ceiling, and construction can be performed more safely and easily.

  The present invention can also be applied to the use of a ventilation fan that is attached to a ceiling or a side wall by using a means for storing a power cord and a portion where the cord is excessively connected.
