The fan main body 14 of the two sets of fan units 11 is connected to the operation unit 12 and the power supply unit 13 via a cable 33, respectively. The cable 33 includes a power cable and a signal cable. The connection structure between the cable 33 and the fan body 14 may be either a first structure or a second structure. In the first structure, the end of the cable 33 is fixed to the fan body 14. In the second structure, the end of the cable 33 can be attached to and detached from the fan body 14 via a plug.

The fan unit 11 can be attached to and detached from the work clothes 34 worn by the worker W1. As shown in FIG. 12, mounting holes 35 are provided at arbitrary locations on the work clothes 34, for example, locations corresponding to the lumbar region of the back body. The work clothes 34 of the present disclosure are provided with mounting holes 35 at a plurality of places, for example, two places. The mounting hole 35 is circular when viewed from the rear of the work clothes 34, and the inner diameter of the mounting hole 35 is equal to or larger than the outer diameter of the tubular portion 20 and smaller than the outer diameter of the flange 23. A set of fan units 11 is attached to one attachment hole 35.

An example of attaching the fan unit 11 to the work clothes 34 will be described with reference to FIGS. 8 and 9. The fan body 14 is arranged on the outer side B1 of the work clothes 34, and the sleeve 15 is arranged on the inner side B2 of the work clothes 34. Further, the sleeve 15 and the tubular portion 20 are arranged concentrically. The tubular portion 20 of the fan body 14 is inserted into the mounting hole 35, and the flange 23 is brought into contact with the work clothes 34. The tubular portion 20 is made to enter the inside of the sleeve 15, and the protrusion 28 of the sleeve 15 is made to enter the notch 26. Further, the operator W1 rotates the fan body 14 and the sleeve 15 relative to each other in the first direction, and the operator tactilely recognizes that the protrusion 28 has passed over the protrusion 27 and stops the fan body 14 and the sleeve 15. Then, the flange 23 and the sleeve 15 are in a state of sandwiching the work clothes 34 as shown in FIG. 9, and the fan unit 11 is attached to the work clothes 34. In this way, the fan body 14 and the sleeve 15 are fixed to each other by the engaging force between the protrusion 27 and the protrusion 28, and the fan unit 11 is assembled as shown in FIG.

With the fan unit 11 attached to the work clothes 34, when the operator W1 operates the operation unit 12 to turn on the power and selects any mode, a voltage is applied from the power supply unit 13 to the electric motor 17. Then, the fan 19 rotates. Then, the air on the outside B1 of the work clothes 34 enters the casing 16 through the intake port 21, and the air in the casing 16 is discharged from the exhaust port 22 to the inside B2 of the work clothes 34. Then, an air flow is forcibly formed on the inner side B2 of the work clothes 34. The air flowing through the inner side B2 of the work clothes 34 passes through the collar portion 36, the sleeve portions 37, etc., and is discharged to the outer side B1 of the work clothes 34. Therefore, it is possible to suppress the air from staying in the inner B2 of the work clothes 34, and it is possible to suppress the temperature rise of the inner B2 of the work clothes 34. Therefore, it can contribute to the heat stroke countermeasures of the worker W1. Further, by making the fan 19 an axial fan that sucks and discharges air in the axial direction of the rotating shaft to which the blades are attached or substantially parallel to the rotating shaft, the blower 10 is made thinner and the air volume is increased. Is possible.

FIG. 13 is a flowchart showing an operation example of the blower device 10. When the operator W1 presses the tactile switch 29 for a predetermined time or longer in step S1, the power is turned on. Turning on the power means that a weak current is supplied from the power supply unit 13 to the controller 31 to start the controller 31. When the operator W1 presses the tactile switch 29 for less than a predetermined time in step S2 while the power is on, the turbo mode voltage is applied to the electric motor 17. The turbo mode voltage means the maximum wind speed voltage. Further, when the tactile switch 29 is pressed for less than a predetermined time in step S3, a strong mode voltage is applied to the electric motor 17. The strong mode voltage means a voltage lower than the turbo mode voltage.

Further, when the tactile switch 29 is pressed for less than a predetermined time in step S4, a medium mode voltage is applied to the electric motor 17. The medium mode voltage means a voltage lower than the strong mode voltage. Further, when the tactile switch 29 is pressed for less than a predetermined time in step S5, a weak mode voltage is applied to the electric motor 17. The weak mode voltage means a voltage lower than the medium mode voltage. Further, when the tactile switch 29 is pressed for a predetermined time or longer in step S6, the power is turned off. The power off means that power is not supplied from the power supply unit 13 to the controller 31. Therefore, the function of the controller 31 is stopped, and the electric motor 17 is stopped.

When the fan unit 11 is removed from the work clothes 34, when the worker W1 rotates the fan body 14 and the sleeve 15 relative to each other in the second direction, the protrusion 28 moves in the mounting groove 25 and gets over the protrusion 27. Then, when the fan body 14 and the sleeve 15 are separated from each other, the protrusion 28 exits from the notch 26. Therefore, the fan body 14 and the sleeve 15 can be separated. In this way, the sleeve 15 is removable from the fan body 14. Further, the fan body 14 is moved with respect to the work clothes 34, and the tubular portion 20 is pulled out from the mounting hole 35.

In addition to the fan unit 11 described above, the blower unit 10 can also configure the fan unit 38 shown in FIG. The fan unit 38 has a fan body 14 and a belt adapter 39. That is, the fan body 14 can be attached to and detached from either the sleeve 15 or the belt adapter 39.

The belt adapter 39 has an adapter main body 40, a hook 41 attached to the adapter main body 40, and a clamp 42 provided on the adapter main body 40. The adapter body 40 is made of synthetic resin or metal, and the adapter body 40 has a tubular storage portion 43 and a storage portion as shown in FIGS. 14, 15, 16, 17, 18, and 19. It has an exhaust pipe 44, which is connected to the end of 43. The exhaust pipe 44 is arranged along the radial direction of the storage portion 43. The exhaust pipe 44 is connected to the fan main body 14 so as to form a predetermined angle with respect to the axial direction of the fan 19. The hook 41 and the clamp 42 are provided on the outer surface of the exhaust pipe 44. In a plan view of the belt adapter 39, the hook 41 is provided on the opposite side of the exhaust pipe 44 where the accommodating portion 43 is connected. The clamp 42 is a plate piece provided in the exhaust pipe 44 in the arrangement area of the storage portion 43 and extended in a direction away from the storage portion 43.

The storage portion 43 can store the fan main body 14 from the opening 45. That is, the inner diameter of the storage portion 43 is larger than the outer diameter of the tubular portion 20 and smaller than the outer diameter of the flange 23. As shown in FIG. 17, a protrusion 46 is provided on the inner surface of the storage portion 43. A plurality of protrusions 46 are provided at intervals in the circumferential direction of the storage portion 43.

When the fan main body 14 is fixed to the adapter main body 40, the fan main body 14 and the storage portion 43 are arranged concentrically with the center line A1 as the center, as shown in FIG. Then, the fan main body 14 and the adapter main body 40 are brought close to each other, and the protrusion 46 is made to enter the notch 26. Next, when the fan main body 14 and the adapter main body 40 are relatively rotated in the first direction, the protrusion 46 moves in the mounting groove 25. The worker W1 tactilely recognizes that the protrusion 46 has passed over the protrusion 27, and stops the fan main body 14 and the adapter main body 40. In this way, the fan unit 38 is assembled. Also in the fan unit 38, the operation unit 12 and the power supply unit 13 are connected to the fan body 14 as shown in FIG.

The worker W1 hangs on the belt 48 of the work trousers 52 shown in FIG. The intake port 21 of the fan body 14 is located below the hem 34A of the work clothes 34. The belt 48 positions the work trousers 52 with respect to the waist of the worker W1. FIG. 21 shows an example in which two sets of fan units 38 are hung on a belt 48 at a position corresponding to the flank of the worker W1. A part of the work clothes 34 covers the belt 48. Further, the exhaust pipe 44 is positioned on the inner side B2 of the work clothes 34, and the hem 34A of the work clothes 34 is inserted between the clamp 42 and the exhaust pipe 44. That is, the clamp 42 supports the hem 34A. The storage portion 43 and the fan main body 14 are located on the outer side B1 of the work clothes 34. The fan unit 38 can be attached not only to the belt 48 but also to any of the positions where the hook 41 can be attached, such as the pocket of the work clothes 34 and the waist of the work trousers 52.

When the operator W1 operates the operation unit 12 to rotate the electric motor 17, the fan 19 rotates. The air on the outside B1 of the work clothes 34 is sucked into the casing 16 from the intake port 21 and discharged into the exhaust pipe 44 from the exhaust port 22. The air in the exhaust pipe 44 is discharged from the exhaust port 47 to the inside B2 of the work clothes 34. Therefore, the fan unit 38 can obtain the same effect as the fan unit 11. Further, since the exhaust pipe 44 has a tubular shape and air is discharged from the exhaust port 47, it is easy to set the discharge direction of the air B2 inside the work clothes 34.

An example of modification of the fan body 14 will be described with reference to FIGS. 22, 23 and 24. The guide rail 24 of the fan body 14 is provided with a plurality of protrusions, for example, three protrusions 49, 50, 51. The protrusions 49, 50, and 51 are arranged at intervals in the circumferential direction of the tubular portion 20.

When the fan body 14 of FIG. 22 is attached to the belt adapter 39, the fan body 14 and the storage portion 43 are arranged concentrically with the center line A1 as the center. The fan body 14 is arranged on the outer side B1 of the work clothes 34, and the belt adapter 39 is arranged on the inner side B2 of the work clothes 34. Then, the tubular portion 20 is inserted into the mounting hole 35, and the work clothes 34 are sandwiched between the flange 23 and the end portion of the storage portion 43.

Here, when connecting the fan body 14 and the belt adapter 39, with the protrusion 46 inserted in the mounting groove 25, the relative position between the fan body 14 and the belt adapter 39 can be arbitrarily set around the center line A1. Can be changed and positioned. The fan unit 38 shown in FIG. 23 is an example in which the protrusion 46 is stopped between the protrusion 49 and the protrusion 50 to position the fan body 14 and the belt adapter 39. The fan unit 38 shown in FIG. 24 is an example in which the fan main body 14 and the belt adapter 39 are positioned by stopping at a position where the protrusion 46 gets over the protrusion 51.

In this way, if the relative positions of the fan body 14 and the belt adapter 39 are arbitrarily changed around the center line A1, the exhaust pipe 44 does not change the position of the fan body 14 in the circumferential direction with respect to the work clothes 34. The direction of the air discharged from the work clothes 34 to the inside B2 can be changed as shown in FIGS. 25 and 26.

In FIG. 25, the belt adapter 39 is attached to the fan body 14 so that the distance between the line segments D1 indicating the directions of the air discharged from the two sets of fan units 38 becomes narrower as the collar portion 36 approaches. An example of positioning is shown. In FIG. 26, the belt adapter 39 is positioned with respect to the fan body 14 so that the distance between the line segments D1 indicating the directions of the air discharged from the two sets of fan units 38 increases as the collar portion 36 approaches. An example of this is shown. Therefore, it is possible for the operator to exhaust the air from the exhaust pipe 44 toward an arbitrary position on the inner side B2 of the work clothes 34.

The fan unit 38 shown in FIGS. 22, 23 and 24 can also be used by hanging the hook 41 on the belt 48 as shown in FIG. 21. When the belt adapter 39 and the fan body 14 are relatively rotated in the second direction and the protrusion 46 is retracted from the mounting groove 25, the fan body 14 and the belt adapter 39 can be separated. In this way, the belt adapter 39 is removable from the fan body 14.
