  Such a conventional ventilator has a problem that the wire spring joined to the louver cannot be properly held in the engaging portion that engages with the wire spring provided in the main body.

  Therefore, the present invention solves the above-described conventional problems, and provides a ventilator that can hold the wire spring joined to the louver properly in the engaging portion that engages with the wire spring provided in the main body. The purpose is to do.

  In order to achieve this object, the present invention provides a wire spring holding portion for holding a wire spring in the wire spring engaging portion, and an inclined shape that increases from the wire spring holding portion toward both sides. The guide portion is provided, thereby achieving the intended purpose.

  According to the present invention, the wire spring engaging portion is provided with the wire spring holding portion for holding the wire spring, and the inclined guide portions are provided on both sides from the wire spring holding portion. In addition, the louver is moved to cover the opening while being in contact with the inclination of the inclined guide portion, and the louver is mounted so as to cover the opening. The effect that it can hold | maintain properly can be acquired.

The ventilator according to claim 1 of the present invention has a ventilation path that leads from the room to the ceiling,
A box having a suction port and a flange on the bottom surface and a ventilation port on the top surface. A louver having a wire spring is provided with a wire spring engaging portion that engages with the wire spring at an upper portion of the flange portion so as to engage with the wire spring, and the wire spring is attached to the wire spring engaging portion. The wire spring holding part to hold | maintain is provided, and it has the structure that the inclined guide part which becomes high toward the both sides from the said wire spring holding part was provided. As a result, the wire spring moves to the wire spring holding portion while being in contact with the inclination of the inclined guide portion, and the louver is attached to cover the opening, so that the wire spring is provided in the wire spring engaging portion. There is an effect that the wire spring can be properly held by the wire spring holding portion.

  Further, the height of the inclined end portion of the guide portion may be configured such that the inner inclined portion end portion close to the suction port is made higher than the outer inclined portion end portion. As a result, the wire spring moves from the position higher than the outer inclined portion end to the wire spring holding portion while making contact with the inner guide portion close to the ventilation path, and the louver is mounted so as to cover the opening. The spring can be securely held in the wire spring holding portion provided in the wire spring engaging portion by the wire spring holding portion provided in the wire spring engaging portion. There is an effect.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1 and FIG. 2, a ventilation path 3 that conducts from the room 1 to the ceiling 2 is provided, a suction port 4 and a flange portion 5 are provided on the bottom surface, a ventilation port 6 is provided on the top surface, and a motor 7 is provided on the top. And a motor holding plate 8, a box body containing a blade 9, for example, a propeller fan, specifically a cylindrical ventilation device 20, and a louver 11 that covers and installs the opening 10 on the bottom surface of the box body from the room 1 side. For example, in order to attach the louver 11 to the lattice-like louver 11, the louver 11 has two bifurcated metal wire springs 12 provided on the back surface of the louver 11 so that the tip thereof is substantially annular, for comparison. The configuration is such that the wire spring engaging portion 13 is engaged and attached.

  When the ventilator 20 is operated, the motor 7 is driven and the blades 9 are rotated, so that the air in the room 1 is sucked from the suction port 4 and discharged from the ventilation port 6 to the ceiling back 2.

  As a method for attaching the louver 11, it is inserted through a wire spring insertion port 14 provided at the lower portion of the flange portion 5 while manually pinching the center portion of the wire spring 12 having a bifurcated shape and a substantially annular tip provided on the back surface of the louver 11. After that, when the hand is released from the wire spring 12, the wire spring 12 spreads and attaches to the wire spring engaging portion 13 provided on the upper portion of the flange portion 5 of the ventilation device 20.

  As shown in FIGS. 2 and 3, the wire spring engaging portion 13 guides the wire spring 12 to the wire spring holding portion 15 and the wire spring holding portion 15 that holds the wire spring insertion port 14 and the wire spring 12. The guide portion 16 has a cylindrical shape, and the guide portion 16 has an inclined shape that increases in the direction from the wire spring holding portion 15 toward the ventilation path 3 and toward both sides in the away direction. When the wire spring 12 is inserted from the wire spring insertion port 14 and is released from the wire spring 12, the wire spring 12 moves toward the wire spring holding portion 15 while being in contact with the inclination of the guide portion 16, and engages with the wire spring holding portion 15. The louver 11 is attached.

  As shown in FIG. 3, for example, when the angle a of the guide portion 16 is desirably 15 degrees or more and the angle is from 0 degree to 15 degrees, the force that the wire spring 12 moves while contacting the guide section 16 is weak. As a result, it becomes difficult to properly hold the wire spring holding portion 15 provided in the wire spring engaging portion 13.

(Embodiment 2)
The same components as those in the first embodiment are denoted by the same reference numerals and detailed description thereof is omitted.

  As shown in FIGS. 4 and 5, the inner inclined portion end portion 17 a close to the ventilation passage 3 of the inclined guide portion 16 that rises from the wire spring holding portion 15 toward both sides of the ventilation passage 3. On the outer wall, it is provided at a position that is higher from the outer inclined portion end 17 b toward the ventilation port 6, and is integrally provided on the outer wall of the ventilation path 3.

  In the above configuration, the wire spring 12 inserted from the wire spring insertion port 14 of the wire spring engaging portion 13 moves to the wire spring holding portion 15 while contacting the inner inclined guide portion 16 close to the ventilation path 3. As a result, the movement in the direction of the ventilation path 3 is limited, and the movement to the direction of contact with the motor lead wire 18 on the ventilation path 3 side is prevented, and the flange portion 5 is engaged when engaged with the wire spring engagement portion 13. The motor lead wire 18 is contacted with the motor lead wire 18 installed toward the ventilation port 6 along the outer wall of the ventilation path 3 from the electrical component 19 installed on the upper side of the motor, and the motor lead wire 18 is damaged. The spring holding portion 15 can no longer be held, and the wire spring holding portion 15 provided in the wire spring engaging portion 13 can be more securely and securely held regardless of the insertion state of the wire spring 12.

  The ventilator according to the present invention can be installed in an air conditioner, a blower, etc., because the main body can be installed on the ceiling or the like in the louver wire spring mounting structure and the louver wire spring can be properly held on the main body. It is useful as a spring mounting for louvers.
