Description

  The present invention relates to a ventilator provided as a terminal opening on a ceiling plate or the like for supplying outdoor air into a room or exhausting indoor air to the outside.

  Conventionally, this type of ventilation device is an example of a mounting configuration of a grill installed on a ceiling surface or the like, and is fixed to a main body of a blowing grill installed on the back of the ceiling with a screw (for example, see Patent Document 1). .

  Hereinafter, the blowing grill described in Patent Document 1 will be described with reference to FIG.

  As shown in FIG. 7, a blow grill 101 as a blow outlet for supplying outdoor air into the room is fixed to the main body with screws through a mounting hole 102 provided inside the blow grill 101 and attached to the ceiling surface. It has been.

JP 2013-204843 A

  Such a conventional blow-out grill 101 supplies outdoor air in an outdoor environment that deteriorates the resin, or uses an organic solvent, or deteriorates the mechanical strength of the resin due to aging or temperature change. For example, when the resin mounting hole 102 is broken, the installation state of the blowing grill 101 does not change, such as tilting, so that it appears normal and the user cannot easily detect the abnormality of the blowing grill 101. It was.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a ventilator that can easily confirm the state of attachment when an abnormality occurs in the grill as a blowout grill.

In order to achieve this object, the present invention is between a body forming a ventilation path communicating the indoor-side opening and the outdoor-side opening therein, the indoor-side opening and the indoor previous SL body In the ventilation device including the grille disposed on the inside of the grille, a mounting hole fixed to the main body with a screw is provided on the indoor side of the grille, and the shaft of the screw penetrates the main body side of the grille. And provided with a metal mounting portion having a hole sized to be engaged with the head of the screw, and providing a gap between the mounting hole of the grill and the hole of the mounting portion. This achieves the intended purpose.

  According to the present invention, there is provided a main body formed with a ventilation path communicating the indoor side opening and the outdoor side opening inside, and a grill provided on the indoor side for communicating the indoor side opening of the main body with the room. The grill has a mounting hole fixed to the main body with a screw, and a metal mounting portion having a hole through which the screw passes at a position on the main body side of the grill, and the mounting hole and the mounting of the grill Since the gap is provided in the hole of the part, even if the attachment hole is broken, the screw of the metal attachment part having a gap distance from the attachment hole is caught in the screw. The effect that the attachment state can be easily confirmed when an abnormality occurs is obtained.

Side sectional view showing the configuration of the ventilation device Front view showing the configuration of a conventional blow grill

  According to a first aspect of the present invention, there is provided a ventilator comprising: a main body having an air passage that communicates the indoor side opening and the outdoor side opening inside; a main body; the indoor side opening of the main body; The grill is provided with a mounting hole that is fixed to the main body with a screw and a metal mounting portion having a hole through which the screw passes at a position on the main body side of the grill. A gap is provided between the mounting hole and the hole of the mounting portion. As a result, even if the mounting hole is damaged, the hole in the metal mounting part that has a gap distance from the mounting hole is caught in the screw, so that the mounting state can be easily checked when an abnormality occurs in the grill There is an effect that it is possible.

  Moreover, you may make it the structure that the attaching part was provided in one place. As a result, even if the mounting hole is damaged, the hole in one metal mounting part with a gap distance from the mounting hole on the screw will be caught and tilted. There is an effect that can be easily confirmed.

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

(Embodiment 1)
As shown in FIGS. 1 to 3, for example, a rectangular indoor opening 1 is connected to the back of the ceiling 11 and a circular outdoor opening 2 is connected to the side so as to be connected to a duct (not shown). A main body 4 having a ventilation passage 3 formed therein is provided.

  And the grill 6 which connects the indoor side opening part 1 of the main body 4 and the room | chamber 5 via the ceiling 11 of the indoor side opening part 1 by the side of the indoor 5 side is provided.

  The grill 6 is generally known, and a plate-like wind direction adjusting plate 12 is provided inside the grill 6.

  The grill 6 is provided with a mounting hole 8 fixed to the main body 4 with a screw 7.

  Then, a plate-like attachment portion 10 made of metal such as aluminum or iron having a hole 9 through which the screw 7 passes is provided at a position on the main body 4 side of the grill 6.

  The structure of the attachment part 10 has, for example, a substantially inverted T shape, and the grill 6 is fixed with a screw at the lower straight portion of the inverted T shape, and is bent inward at approximately the right end at the uppermost end of the upper straight portion. A hole 9 is provided in a plate shape.

  And it consists of what provided the clearance gap of about 3 mm in the hole 9 of the attachment hole 8 of the grille 6, and the attachment part 10. FIG.

  As shown in FIG. 4, when the mounting hole 8 (see FIG. 3) is damaged and falls downward due to its own weight, the screw 7 has a hole 9 in the metal mounting portion 10 that is spaced from the mounting hole 8 by a gap. Since the grille 6 appears to fall down from the ceiling 11 toward the room 5 side by the distance corresponding to the gap, when the grille 6 becomes abnormal, it is possible to easily confirm the attachment state of the grille 6 to the main body 4.

  In FIG. 3, the mounting holes 8 are provided at two diagonal positions of the opening of the cylindrical portion of the grill 6, but may be provided at four corners (when the shape of the blowing grill 6 is square). Because it can be placed in a balanced manner.) However, even if the holes 9 are provided at two diagonal positions, the function and effect are not different.

(Embodiment 2)
5 and 6, the same components as those in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  And the metal attachment part 10 with the hole 9 is provided in the grill 6 in one place.

  As a result, when the mounting hole 8 is damaged and falls down due to its own weight, the screw 9 has a hole 9 in one of the metal mounting portions 10 that is spaced from the mounting hole 8 by a gap. Since the direction without the attachment portion 10 is inclined downward with respect to the direction with the attachment portion 10, the state of attachment of the grill 6 to the main body 4 should be clearly and easily confirmed when an abnormality occurs in the grill 6. Can do.

  As in the first embodiment, the mounting holes 8 are provided at two locations on the diagonal line of the opening of the cylindrical portion of the grill 6, but may be provided at four locations at the four corners (the shape of the blowing grill 6 is In the case of a square, it can be arranged with good balance.) However, even if the hole 9 is provided at any one of the four corners, the action and effect are not different.

  Since the ventilator according to the present invention enables the attachment state to be easily confirmed when an abnormality occurs in the grill as a blowout grill, the ventilator installed on the lower surface of an outdoor eave or the like Useful as.
