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

(Embodiment 1)
As shown in FIG. 1 and FIG. 2, the ventilation device that uses the illumination and the ventilation function of Embodiment 1 of the present invention is installed on the wall 2 of the toilet space 1, and the indoor toilet space 1 and the outdoor 3 A main body part 5 extending along the room side of the ventilation port 4 penetrating through the vent hole 4 and a protrusion 6 projecting from the main body part 5 toward the wall so as to be inserted into the ventilation port 4 so as to connect the outer periphery. The blowout part 7 is formed. Further, a shutter 8 is configured to freely open and close the blowout portion 7 and to control the inflow and outflow of air in the indoor toilet space 1 and the outdoor 3.

  Next, the fan motor 9 and the air passage of the fan motor 9 are formed on the right side from the wall portion 2 in the immediate vicinity of the indoor side, and the panel 10 for the purpose of forming the appearance for the design purpose is the room of the fan motor 9. A panel suction part 11 through which the air of the panel 10 can flow in and out is formed in the interior of the fan motor 9 so as to cover the inside of the fan motor 9, and further, an air filter that is engaged with and removable from the panel suction part 11 12 is installed.

  Further, a human sensor 13 is arranged on the panel 10 facing the wall 2 in the lower right direction, that is, below the fan motor 9 and on the lower right side of the panel suction portion 11.

  Moreover, the illumination part 14 which irradiates the toilet space 1 is installed in the left side toward the wall part 2, and this illumination part 14 is attached so that it may incline to the center part of the main-body part 5. FIG.

  Here, in the vicinity of the illumination unit 14, the air temperature rises due to the heat generated by the illumination unit 14, and this air may be erroneously detected as a person entering the room by flowing over the human sensor 13. As in the air flow 21, the air heated by the illumination unit 14 passes through the control unit 15 by the air conveyance of the fan motor 9, is sucked into the panel suction unit 11, and is discharged from the blowing unit 7 to the outdoor 3 . Here, since the human sensor 13 is disposed in a place separated from the air flow 21, it can operate normally without performing erroneous detection during ventilation and lighting operation.

  Further, in the above configuration, the lighting unit 14, the control unit 15, and the fan motor 9 are arranged from the left toward the wall unit 2, so that warmed air can come into contact with the human sensor 13 during lighting and ventilation operations. Therefore, the malfunction of the human sensor can be prevented. Furthermore, because of the arrangement, as shown in FIG. 2, it does not interfere with the opening of the lower suction portion 17, so that the pressure loss due to the presence of the human sensor is prevented as much as possible and the malfunction of the human sensor is prevented. Can do.

  Further, as shown in FIG. 2, the installation location of the human sensor 13 is almost always installed at a high place in the toilet space 1 by arranging the detection direction obliquely downward. The performance with which the human sensor 13 detects a person can be greatly improved.

  The ventilation device according to the present invention is configured to provide the human sensor unit at a position far away from the illumination unit, thereby preventing the human sensor from malfunctioning during ventilation operation. Therefore, it is useful as a ventilator that uses both indoor lighting and a ventilation function used for a toilet.
