The holder 51 is fixed to opposite wall surfaces of the suction portion 33 by bolts (or welding or the like) (not shown) at both ends in the longitudinal direction. The holder 51 ensures strength by its material and thickness (in the height direction shown in the drawing).

  The bearing member 53 supports the rotary shaft 54 so as to be rotatable in the radial direction. The bearing member 53 is not limited to a bearing as long as the rotating shaft 54 can be rotatably supported. Further, if the bearing member 53 can be fitted into the holder 51 so as to rotate integrally with the rotating shaft 54, the bearing member 53 is supported by the holder 51 as a simple stopper in the thrust direction (downward) of the rotating shaft 54. Thereby, the bolt 52 can be made unnecessary, and the bearing member 53 can be configured integrally with the rotating shaft 54. At this time, the bearing member 53 may be a simple flange or the like.

  The fan main body 55 includes a base 57 fixed to the rotation shaft 54 and a plurality of propellers 58 integrated with the base 57.

  The propeller 58 is set in shape and orientation so that outside air is taken into the hood body 3 from the air inlet 35. The size and number of the propellers 58 are arbitrarily set according to, for example, the size of the ventilation opening 21, the space on the indoor side (kitchen space), the exhaust power of an exhaust fan for exhaust installed in the same indoor space, and the like. . In the present embodiment, as shown in FIG. 2, four pieces of the same shape and size are provided on the base 57.

  The brush member 6 includes a straight (rod-shaped or plate-shaped) handle 61 and a flock 62 arranged on the handle 61. As shown in FIG. 2, by positioning the handle 61 between the plurality of propellers 58, a wiped object such as dust that has been wiped off can be dropped from between the plurality of propellers 58 and deposited on the upper surface of the propeller 58. Can be suppressed. In addition, it is preferable to use the thing of the material which has charging property so that the flock 62 may collect, wiping off the deposit | attachment adhering to the filter member 4. This charging property may be an electrical process.

  The foreign matter removal filter 7 removes fine dust and the like that has passed through the mesh of the filter member 4 and is made of a material that allows passage of air. In addition, for example, a urethane sponge or the like may be used for the foreign matter removal filter 7, but an ultra-high performance filter (hepa filter) that maintains a high cleanliness may be used to impart a sterilizing effect.

  In such a basic configuration, the ventilation device 1 according to the present embodiment is attached to the outer wall surface 22 of the building so as to cover the ventilation port 21 penetrating indoors and outdoors from the outdoor side, and the air intake port at the downward upstream end A hood body 3 provided with 35, and a mesh-like filter member 4 disposed inside the hood body 3 so as to face the intake port 35 in the middle of the intake path 34 from the intake port 35 to the ventilation port 21; The intake fan 5 that rotates upstream of the filter member 4 on the upstream side of the intake path 34 and that extends in the vertical direction about the rotation shaft 54, and the brush member that is provided on the rotation shaft 54 and contacts the bottom surface of the filter member 4 6 is to improve the hygiene while maintaining the intake efficiency.

  Specifically, when a ventilator for exhausting air indoors and outdoors, which is different from the ventilator 1 according to the present embodiment, is driven, a pressure difference occurs between the indoor side and the outdoor side with the outer wall 2 as a boundary. To do. Basically, the pressure on the indoor side is lower than that on the outdoor side.

  As shown in FIG. 3, the intake fan 8 has a bearing 81 fixed to the holder 81 via a holder 81 having both ends fixed to opposing wall surfaces of the suction portion 33 that is close to the intake port 35, and a bolt (or nut) 82. 83, a rotating shaft 84 whose lower end is rotatably supported by the bearing member 83, and a fan main body 85 fixed near the lower end of the rotating shaft 84. The intake fan 8 rotates about a rotation shaft 84 that is upstream of the filter member 4 and upstream of the intake path 34 and extends in the vertical direction.

  The holder 81 is a shaft member made of metal such as aluminum, and has a width (in the depth direction on the paper) that does not obstruct the opening area of the air inlet 35 as much as possible. The holder 81 has both ends in the longitudinal direction fixed to opposing wall surfaces of the suction portion 33 by bolts (or welding or the like) (not shown). The holder 81 ensures strength by its material and thickness (the height direction in the drawing).

  The bearing member 83 supports the rotating shaft 84 so as to be rotatable in the radial direction. The bearing member 83 is not limited to a bearing as long as the rotation shaft 84 can be rotatably supported. Further, if the bearing member 83 can be fitted into the holder 81 so as to rotate integrally with the rotating shaft 84, the bearing member 83 is supported by the holder 81 as a simple stopper in the thrust direction (downward) of the rotating shaft 84. Thereby, the bolt 82 can be made unnecessary and the bearing member 83 can be configured integrally with the rotating shaft 84. At this time, the bearing member 83 may be a simple flange or the like.

  The fan body 85 includes a shaft-like base 86 fixed to the upper end of the rotating shaft 84 and a plurality of propellers 87 integrated with both ends of the base 86.

  The propeller 87 is set in shape and orientation so that outside air is taken into the hood body 3 from the air inlet 35. As shown in FIG. 4, in this embodiment, a plurality of propellers 87 are provided at regular intervals along the rotation direction of the intake fan 8. In this embodiment, the propeller 87 is centered on the rotation shaft 84. A pair is provided so as to extend linearly in directions away from each other.

In the present embodiment, two sheets having the same shape and size are provided on the base 86.

  The brush member 9 is attached to a pair of propellers 87 constituting the intake fan 8. In the present embodiment, the brush member 9 is arranged along the edge portion on the downstream side in the rotational direction of the intake fan 8 among the edge portions extending linearly in the radial direction of the pair of propellers 87. The brush member 9 includes a straight (rod-like or plate-like) handle 91 and a flocked hair 92 provided on the handle 91. As shown in FIG. 4, the brush member 9 is wiped by disposing it along the edge on the downstream side in the rotation direction of the intake fan 8 among the edges extending linearly in the radial direction of the pair of propellers 87. Wipes such as dust can be dropped from between the plurality of propellers 87 and can be prevented from being deposited on the upper surface of the propeller 87. In addition, it is preferable to use the material with the charging property so that the flock 92 may collect while wiping off the adhering matter adhering to the filter member 4. This charging property may be an electrical process.

  Further, the brush member 9 is disposed along a part of the edge portion extending in the radial direction of the plurality of propellers 87. At this time, as shown in FIG. 4, the entire length of the brush member 9 is supplemented with respect to the radial length of the pair of propellers 87. That is, the brush member 9 is divided into two parts with respect to the rotation trajectory of the pair of propellers 87, the brush member 9 wiping the inner predetermined diameter range and the brush member 9 wiping the outer predetermined diameter range. The number of propellers 87 and the number of divisions need not be the same.

  Even in such a configuration, the intake fan 8 rotates and the brush member 9 rotates via the rotation shaft 84 as in the above embodiment. Since the bristles 92 of the brush member 9 are in contact with the bottom surface of the filter member 4, the collected matter such as dust collected by the filter member 4 by the rotation of the brush member 9 when taking in outside air is wiped off. Thus, the hygiene can be improved while maintaining the intake efficiency.

  As described above, the ventilation device according to the present invention improves the hygiene while maintaining the intake efficiency by enabling the brush member to wipe off the adhering matter adhering to the mesh filter member along with the rotation of the intake fan. This is useful for general ventilators for taking outdoor air into the indoor side.
