  The conventional ventilator 101 is used by suspending it on a joist, a large draw A or the like, or placing it on the ground under the floor, but the height of the ventilator 101 depends on the size of the space under the floor or the ceiling. Ventilation efficiency may vary greatly depending on the directional position. Further, depending on the shape or structure of the floor, the back of the ceiling, etc., the ventilation device 101 may not be installed at an appropriate place.

  Moreover, once the conventional ventilator 101 is suspended in joist, large draw A, etc. or placed on the ground under the floor, the position of the air blowing port 102 cannot be changed. That is, the direction of outflow of air to the surroundings cannot be changed, and efficient ventilation may not be possible depending on the shape or structure of the floor, the back of the ceiling, or the like.

  The present invention has been made in view of such problems, and can perform efficient ventilation regardless of the size of the space under the floor, the back of the ceiling, etc., and the shape of the under floor, the back of the ceiling, etc. It is another object of the present invention to provide a ventilator that can install a ventilator at an appropriate place regardless of the structure, and can change the position of the air blowing port even after the installation, and perform efficient ventilation. .

  In order to achieve the above object, the ventilator according to the present invention has a blower port and an intake port formed in a casing, and a main body portion in which a blower fan is disposed in the casing, and a standing plate portion of the holding body. It is characterized by comprising a suspension support part in which the movable plate can be moved up and down, or a mounting support part in which a plurality of support legs can be moved up and down along the side surface part of the casing.

  The ventilator according to the present invention further includes a fitting groove forming plate fixed to the casing and a holding plate portion of the holding body, and is fitted to the fitting groove forming plate at a predetermined interval in the circumferential direction. A mating groove is formed, a protrusion is formed on the holding plate portion, and a rotation mechanism that allows the protrusion to be fitted is provided in the fitting groove.

  Hereinafter, an embodiment of a ventilator of the present invention will be specifically described with reference to the drawings.

  As shown in FIGS. 1 to 3, the ventilation device 1 of the present invention includes a main body portion 2, a suspension support portion 3, a placement support portion 4, and a rotation mechanism portion 5.

As for the main-body part 2, the casing 21 exhibits a substantially windmill shape, the air blower port 22 is formed in the peripheral part at the circumferential direction equal intervals, and the air inlet 23 is formed in the bottom face. Further, a multiblade fan (not shown) such as a sirocco fan is disposed in the casing 21.
Then, by rotating the multi-blade fan, air is sucked from the air inlet 23 and air is discharged from the air outlet 22. As a result, the surrounding air is agitated and ventilation in the vicinity of the installation location is performed.

The suspension support portion 3 includes a moving plate 31 formed by bending a flat plate into a substantially L shape, and a holding body 32. The moving plate 31 has a long groove portion 31a, and the standing plate portion 33 of the holding body 32 has a standing plate portion 33. A screw hole 33a is formed.
Then, if the bolt is inserted into the long groove portion 31a, screwed into the screw hole 33a, and the bolt is loosened, the moving plate 31 can move up and down along the standing plate portion 33, and if the bolt is tightened, the moving plate 31 is fixed to the standing plate portion 33.

The mounting support portion 4 includes four support legs 41 and a butterfly screw 42, and is slidably installed on the side surface portion of the casing 21 and in the middle of each air blowing port 22.
If the butterfly screw 42 is loosened, the support leg 41 can be moved up and down, and if the butterfly screw 42 is tightened, the support leg 41 is fixed.

The rotation mechanism unit 5 includes a fitting groove forming plate 24 fixed to the upper surface of the casing 21 and a holding plate portion 34 of the holding body 32.
The fitting groove forming plate 24 is formed with fitting grooves 24a, 24a,... At predetermined intervals in the circumferential direction, and elastically biased protrusions 34a, 34a are formed on both sides of the holding plate portion 34. The protrusions 34a, 34a can be freely fitted in the fitting grooves 24a, 24a,.

  According to the ventilator 1 of the present invention, if the moving plate 31 of the suspension support portion 3 is moved up and down along the standing plate portion 33 of the holding body 32, the moving plate 31 can be appropriately projected upward. If the movable plate 31 is fixed at an appropriate place such as joist or large draw, the main body 2 of the ventilator 1 can be appropriately suspended and set at a height direction position.

  Moreover, if the four support legs 41 of the mounting support part 4 are moved up and down, the support legs 41 can be appropriately protruded downward, and the four support legs 41 can be mounted at appropriate locations on the ground below the floor. If it does so, the main-body part 2 of the ventilator 1 can be mounted and set to a height direction position suitably.

  Further, in the rotation mechanism unit 5, if the holding plate portion 34 of the holding body 32 is rotated and the protrusions 34 a and 34 a are fitted into the fitting grooves 24 a and 24 a as appropriate with the fitting groove forming plate 24, The position of 22 can be changed as appropriate, the outflow direction of air to the surroundings can be changed, and efficient ventilation can be performed.

  Further, in the ventilation device 1 of the present invention, the movable plate 31 and the holding body 32 can be attached to the main body 2, so when the ventilation device 1 is suspended and set, the movable plate 31 and the holding body 32 are mounted on the main body. When the ventilation device 1 is mounted and set on the unit 2, the movable plate 31 and the holding body 32 may be detached from the main body unit 2, and in an appropriate state depending on the shape or structure of the underfloor, ceiling, etc. Ventilation device 1 can be installed.

It is the external appearance perspective view which looked at the ventilation apparatus of this invention from the upper direction. It is the external appearance perspective view which looked at the ventilation apparatus of this invention from the downward direction. It is explanatory drawing which shows the installation state of the ventilation apparatus described in FIG. It is a front view of the ventilation apparatus of this invention.
