{Description of installation method}
When attaching the blower 100 to air-conditioning clothes or the like, as shown in FIG. After inserting the air blower 100 into a hole (not shown) so that the air intake portion 22 faces the outer surface side, a sheet-like air blower is inserted into the groove portion 234 formed between the outer surface side flange 232 and the inner surface side flange 233 . The edge around the mounting hole of the member 200 is dropped.

At this time, since the outer flange 232 is formed to have a smaller diameter than the inner flange 233, the edge around the attachment hole of the sheet-like member 200 is pushed from the outer flange 232 side. It is easy to drop it into the groove portion 234 .

In addition, in order to facilitate attachment of the blower 100 to the attachment hole of the sheet-like member 200 as described above and to make it difficult to remove the blower 100, a ring-shaped rubber or the like is provided around the attachment hole of the sheet-like member 200. It is desirable that the elastic member is sewn into the mounting hole so that the periphery of the mounting hole has elasticity.

{Explanation of effect}
According to this embodiment, outside air introduced into the blower 100 from the air intake portion 22 of the case body 2 is discharged from the air exhaust portion 24 formed in a direction substantially perpendicular to the rotating shaft of the motor 11 by the internal fan main body 1. Ejected.
For this reason, the air flow formed by the fan main body 1 becomes a flow in a direction parallel to the body without changing the direction. No need to change times.
Therefore, there is no loss when changing the direction of the air flow, and the cooling efficiency can be improved.

Further, in the case of a structure in which an annular locking member is inserted into the tubular portion of the fan body from the inner surface side of the sheet-like member and fixed, as in the conventional blower device, the tubular portion and the locking member are attached to the fan body. Because it is positioned to the side of the blade, it interferes with the exhaustion of air from the blower in a direction substantially perpendicular to the rotation axis of the motor.
On the other hand, according to the present embodiment, since the blower 100 is attached to the sheet-like member 200 by the groove 234 between the outer flange 232 and the inner flange 233, the attachment portion 23 is excluded. Most of the side surfaces of the case body 2 can be used as the exhaust part 24, and the exhaust of the air from the blower 100 is not hindered.

In addition, when it is necessary to change the direction of the air flow by 90 degrees as in the conventional blower, the sheet-shaped member formed by the fan main body and the air flow in the direction substantially perpendicular to the inside or outside of the blower are provided. , it is essential to provide a space for converting to a direction substantially parallel to the sheet-like member. Therefore, it is difficult to form the vicinity of the air blower such as air-conditioning clothes to be thin.
On the other hand, according to the blower device 100 according to the present embodiment, the air flow is formed in a direction substantially parallel to the sheet-like member 200 by the fan body 1, so there is no need to provide such a space. , the vicinity of the air blower, such as air-conditioning clothes, can be formed thin.

In addition, when it is necessary to change the direction of the air flow by 90 degrees as in the conventional blower, noise is likely to occur in the process. Quietness can also be improved because there is no need to change the flow direction.

{Modification}
As shown in FIG. 5, the mounting portion 23A may be formed by a ring-shaped member 231A in which a groove is dug into the outer circumference and a groove portion 234A is formed without the outer surface side flange 232 and the inner surface side flange 233. .

As shown in FIG. 6, after forming the mounting portion 23 so that the width of the groove portion 234 in the vertical direction is larger than the thickness of the sheet-like member 200, the groove portion 234, in addition to the sheet-like member 200, has elasticity. The elastic ring 3, which is an annular member having an inner diameter substantially the same as the outer diameter of the ring-shaped member 231, is attached so that the edge around the mounting hole of the sheet-shaped member 200 is It may be pressed against the upper or lower wall of the groove 234 , that is, the lower surface of the outer flange 232 or the upper surface of the inner flange 233 . Note that FIG. 6 illustrates a case where the elastic ring 3 is attached above the sheet-like member 200 and the sheet-like member 200 is pressed against the upper surface of the inner flange 233 .
This makes it more difficult for the air blower 100 to come off from the attachment hole of the sheet member 200 .

In addition, the elastic ring 3 may be formed in an elliptical shape. When formed in an elliptical shape, the inner circumference is larger than the outer circumference of the ring-shaped member 231 and the minor axis of the inner circumference is formed to be smaller than the diameter of the outer circumference of the ring-shaped member 231 . As a result, the short diameter side of the elastic ring 3 strongly contacts the ring-shaped member 231, making it more difficult for the blower device 100 to come off.
When the elliptical elastic ring 3 is attached, it may be attached after pinching the major diameter side with fingers to form a perfect circle with a diameter larger than that of the ring-shaped member 231 .

[Second embodiment]

In this case, the inner flange 233 does not necessarily have to be formed at the lower end of the ring-shaped member 231, and can be formed at any position on the ring-shaped member 231 as long as a space for the male screw portion 235 can be secured. is.

In addition, as shown in FIG. 7B, the blower device 100B according to the second embodiment has a vertical width approximately equal to the vertical width of the portion above the inner flange 233 of the ring-shaped member 231. The mounting ring 4 is an annular member formed to have the same inner diameter and substantially the same outer shape as the ring-shaped member 231 .
The inner surface side of the mounting ring 4 is provided with a female threaded portion (not shown) that is screwed with the male threaded portion 235 .

In this embodiment, as shown in FIG. 8, the case body 2 is inserted into the mounting hole of the sheet-like member 200 from the inner surface side of the sheet-like member 200, and the upper surface of the inner surface-side flange 233 is attached to the mounting hole of the sheet-like member 200. After contacting the edge around the hole, the mounting ring 4 is inserted into the ring-shaped member 231 of the mounting portion 23 from the outer surface side of the sheet-shaped member 200, and the male screw portion 235 and the female screw of the mounting ring 4 are inserted. screw the parts together. As a result, the mounting ring 4 is fixed to the case body 2 with the edge of the sheet member 200 around the mounting hole sandwiched between the lower end of the mounting ring 4 and the upper surface of the inner flange 233 . Then, the air blower 100B can be attached to the sheet member 200. As shown in FIG.

Note that, contrary to the above, the ring-shaped member 231 may be provided with a female screw portion, and the mounting ring 4 may be provided with a male screw portion.

Further, the method for fixing the ring-shaped member 231 and the mounting ring 4 is not limited to the method using screws, and any configuration can be adopted as long as both can be fixed.

For example, a configuration may be used in which a protrusion provided on the inner surface of the mounting ring 4 is engaged with a recess provided on the outer surface of the ring-shaped member 231 .

In this case, the mounting ring 4 may be formed in a perfect circular shape, but may be formed in an elliptical shape with projections formed on the inner surface on the minor diameter side. In this case, the inner circumference is larger than the outer circumference of the ring-shaped member 231 and the short diameter of the inner circumference is smaller than the diameter of the outer circumference of the ring-shaped member 231 . As a result, the projection provided on the minor diameter side of the mounting ring 4 strongly engages with the recessed portion of the ring-shaped member 231, making it difficult for the blower device 100 to come off.
When attaching the elliptical attachment ring 4 , the long diameter side may be pinched with fingers to form a perfect circle with a diameter larger than that of the ring-shaped member 231 before attachment.

This embodiment can also provide the same effects as those of the first embodiment.
