Part. The second intake port portion 111G includes a plurality of through holes formed in the second wall portion 111D. These through-holes, that is, the second air inlet 111G are opened in a direction intersecting the drive shaft 123 (in this embodiment, the output axis orthogonal direction 123B) (substantially parallel to the user's back). The air flow path passing through the second air inlet 111G extends in a direction intersecting the drive shaft 123. Note that the number of through holes that constitute the second intake port portion 111G need only be open in the direction intersecting the drive shaft 123, and the number and arrangement position thereof are not limited to the illustrated example.

On the other hand, the exhaust port portion 112 </ b> A configured similarly to the first embodiment is provided in the second main body portion 112. More specifically, as shown in FIG. 25, FIG. 27 and FIG. 28, the second main body 112 is formed in a circular dome shape protruding in the direction away from the first main body 111 in the output shaft direction 123A, and is formed inside. Two blower unit accommodating portions 112B for accommodating the blower unit 120 are included. The exhaust port portion 112A includes a plurality of through holes formed in the blower unit housing portion 112B. These through-holes, that is, the exhaust port portion 112A, open in the output shaft direction 123A (specifically, in the direction opposite to the first main body portion 111 in the output shaft direction 123A (in the direction of the user's back)). Yes. In the present embodiment, these through holes are also opened in the direction intersecting the drive shaft 123. The through holes constituting the exhaust port portion 112A only need to open at least in the output axis direction 123A, and the number and arrangement position thereof are not limited to the illustrated example.

As shown in FIG. 28, the blower unit 120 includes a drive motor 121 and a fan 124 as in the first embodiment. In the present embodiment, unlike the first embodiment, in the output shaft direction 123A, the length of the drive motor main body 122 is set to be approximately the same as or slightly longer than the length of the blade 126 of the fan 124. Compared to a general brushed motor, it is shorter. In the present embodiment, the diameter of the fan 124 is 63 mm.

In the present embodiment, the operation unit 140 that is manually operated by the user is provided in the battery receiving unit 170 as in the twelfth embodiment (see FIG. 22). In this embodiment, the drive motor 121 is configured as a so-called circuit-integrated brushless motor, and the central processing unit 142 (see FIG. 8) is a circuit board (not shown) together with a switching element and a rotor position detection sensor. ) And built in the drive motor 121.

An intake port portion 111E including the portion 111G is provided. Therefore, the air blower 100N can efficiently intake air from different directions. Therefore, the thickness in the output shaft direction is reduced while securing the intake air amount equivalent to the case where only the air inlet portion 111A opening in the direction intersecting the drive shaft 123 is provided as in the air blower 100A of the first embodiment. Therefore, further downsizing can be achieved.

Further, by adopting a small and high-output brushless motor as the drive motor 121, in addition to shortening the output shaft direction 123A, the diameter of the fan 124 is also reduced. In a blower that employs a conventional motor with a brush, the fan diameter is generally 80 mm or more. On the other hand, in this embodiment, the diameter of the fan 124 is reduced to 63 mm while ensuring an air volume equivalent to such a conventional blower. Thus, the overall downsizing of the air blower 100N of the present embodiment is realized.

Furthermore, in this embodiment, since the operation part 140 is provided in the battery receiving part 170, it is not necessary to provide the operation main-body part 141 separately, and can reduce a number of parts and can improve the usability of a user. In addition, since the drive motor 121 is configured as a circuit-integrated brushless motor, the central processing unit 142 does not need to be mounted on other components, and the number of components can be reduced and wiring can be simplified.

The blower according to the present invention is not limited to the configurations according to the first to fourteenth embodiments described above. For example, the configurations described in the first to fourteenth embodiments can be combined as appropriate.

Further, for example, a single blower unit 120 may be accommodated in the blower main body 110 as in the blower 100P shown in FIG. A plurality of blowers 100 </ b> P may be mounted on the work jacket 200 and used. In addition, in FIG. 29, the example with which the two air blower 100P was mounted | worn is illustrated.

It is also possible to provide a new configuration for providing other functions. For example, a remaining amount detection unit for the battery 180 may be provided, and the central processing unit 142 may be configured to detect the remaining amount of the battery 180 and rotate the drive motor 121 at a rotation speed corresponding to the remaining amount. it can. With this configuration, the drive motor 121 can be driven for a long time (e.g., 8 hours), so that it is possible to avoid a situation in which the air blow stops unexpectedly during the work.
Moreover, an ion generator can be provided in the blower main body 110.
