Each of the plurality of guide rails 24 has a protrusion 27 protruding toward the mounting groove 25.

  The sleeve 15 is made of synthetic resin or metal and has an annular shape as shown in FIGS. The inner diameter of the sleeve 15 is larger than the outer diameter of the cylindrical portion 20 and smaller than the outer diameter of the flange 23. A protrusion 28 is provided on the inner peripheral surface of the sleeve 15. A plurality of protrusions 28 are provided at intervals in the circumferential direction of the sleeve 15. The number of protrusions 28 is the same as the number of notches 26.

  The operation unit 12 includes a tactile switch 29 shown in FIG. 11, a lamp 30, and a controller 31 shown in FIG. The controller 31 is a microcomputer including a central processing unit, a storage unit, and an input / output interface. The controller 31 is connected to the inverter circuit 18, the tactile switch 29 and the lamp 30. By operating the tactile switch 29, it is possible to switch the power on and off and switch various modes. The number of lighting or the lighting position of the lamp 30 is different depending on the on / off of the tactile switch 29 and the type of mode. The controller 31 controls the inverter circuit 18 by switching various modes while the power is on.

  The power supply unit 13 is connected to the electric motor 17 via the inverter circuit 18. The power supply unit 13 includes a storage case 32 and battery cells stored in the storage case 32. The battery cell is a secondary battery that is a DC power source and can be repeatedly charged and discharged. As the battery cell, any of a lithium ion battery, a nickel metal hydride battery, a lithium ion polymer battery, and a nickel cadmium battery can be used. The fan main bodies 14 of the two sets of fan units 11 are connected to the operation unit 12 and the power supply unit 13 via cables 33, respectively. The cable 33 includes a power cable and a signal cable. The connection structure between the cable 33 and the fan main body 14 may be either the first structure or the second structure. In the first structure, the end of the cable 33 is fixed to the fan main body 14. In the second structure, the end of the cable 33 is detachable from the fan main body 14 through 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, the attachment hole 35 is provided at an arbitrary position of the work clothes 34, for example, a position corresponding to the waist part of the back body. The work clothes 34 of the present disclosure are provided with attachment holes 35 at a plurality of places, for example, two places. The attachment hole 35 is circular in the rear view of the work clothes 34, and the inner diameter of the attachment hole 35 is equal to or larger than the outer diameter of the cylindrical portion 20 and smaller than the outer diameter of the flange 23. One 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 main 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 cylindrical portion 20 are arranged concentrically. The cylindrical portion 20 of the fan main body 14 is inserted into the attachment hole 35, and the flange 23 is brought into contact with the work clothes 34. The cylindrical portion 20 is caused to enter the inside of the sleeve 15, and the protrusion 28 of the sleeve 15 is caused to enter the notch 26. Further, the operator W1 relatively rotates the fan main body 14 and the sleeve 15 in the first direction, and the operator recognizes that the protrusion 28 has climbed over the protrusion 27 by touch, and stops the fan main 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 main 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 worker W1 operates the operation unit 12 to turn on the power and selects any mode, voltage is applied from the power supply unit 13 to the electric motor 17. Then, the fan 19 rotates. Then, the air on the outer side B1 of the work clothes 34 enters the casing 16 through the air inlet 21, and the air in the casing 16 is discharged from the exhaust port 22 to the inner side B2 of the work clothes 34. Then, an air flow is forcibly formed on the inner side B <b> 2 of the work clothes 34. The air flowing through the inner side B2 of the work clothes 34 passes through the collar part 36, the sleeve part 37, etc., and is discharged to the outer side B1 of the work clothes 34. For this reason, it can suppress that air retains in the inner side B2 of the work clothes 34, and can suppress the temperature rise of the inner side B2 of the work clothes 34. Therefore, it can contribute to the heat stroke countermeasure of the worker W1. Further, the fan 19 is 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, thereby reducing the thickness of the blower 10 and increasing the air volume. Is possible.

  FIG. 13 is a flowchart illustrating an operation example of the blower 10. When the operator W1 presses the tactile switch 29 for a predetermined time or more in step S1, the power is turned on. The power-on means that a weak current is supplied from the power supply unit 13 to the controller 31 and the controller 31 is activated. 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 a predetermined time in step S <b> 3, 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 a predetermined time in step S <b> 4, the 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 a predetermined time in step S <b> 5, 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. “Power off” means that power is not supplied from the power supply unit 13 to the controller 31. For this reason, 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 relatively rotates the fan main body 14 and the sleeve 15 in the second direction, the protrusion 28 moves in the attachment groove 25 and gets over the protrusion 27. Then, when the fan main body 14 and the sleeve 15 are separated from each other, the protrusion 28 is retracted from the notch 26. Therefore, the fan main body 14 and the sleeve 15 can be separated. Thus, the sleeve 15 is detachable from the fan main body 14. Further, the fan main body 14 is moved with respect to the work clothes 34, and the cylindrical portion 20 is extracted from the attachment hole 35.

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

  The belt adapter 39 includes 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 main body 40 is made of synthetic resin or metal, and the adapter main body 40 includes a cylindrical storage portion 43 and a storage portion as shown in FIGS. 14, 15, 16, 17, 18, and 19. And an exhaust pipe 44 connected to the end of 43. The exhaust pipe 44 is disposed along the radial direction of the storage portion 43. The exhaust pipe 44 is connected to the fan 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 location where the storage portion 43 is connected to the exhaust pipe 44. The clamp 42 is a plate piece provided in the exhaust pipe 44 and extending in a direction away from the storage portion 43 in the arrangement region of the storage portion 43.

  The storage unit 43 can store the fan main body 14 through the opening 45. That is, the inner diameter of the storage portion 43 is larger than the outer diameter of the cylindrical 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 fixing the fan main body 14 to the adapter main body 40, as shown in FIG. 20, the fan main body 14 and the storage portion 43 are arranged concentrically around the center line A1. Then, the fan main body 14 and the adapter main body 40 are brought close to each other, and the protrusion 46 enters 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 recognizes that the protrusion 46 has passed over the protrusion 27 with a tactile sensation, and stops the fan main body 14 and the adapter main body 40. In this way, the fan unit 38 is assembled. 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.

  Worker W1 hangs on belt 48 of work pants 52 shown in FIG. The air inlet 21 of the fan main body 14 is located below the hem 34 </ b> A of the work clothes 34. The belt 48 positions the work pants 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 the 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 B <b> 2 of the work clothes 34, and the skirt 34 </ b> A of the work clothes 34 is inserted between the clamp 42 and the exhaust pipe 44. That is, the clamp 42 supports the skirt 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 is not limited to the belt 48 and can be attached to any position where the hook 41 can be attached, such as a pocket of the work clothes 34 or a waist part of the work pants 52.

  When the operator W1 operates the operation unit 12 to rotate the electric motor 17, the fan 19 rotates. The air on the outer side 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 exhausted from the exhaust port 47 to the inner side B <b> 2 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 cylindrical shape and exhausts air from the exhaust port 47, it is easy to set the discharge direction of the air B2 inside the work clothes 34.

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

  When attaching the fan main body 14 of FIG. 22 to the belt adapter 39, the fan main body 14 and the accommodating part 43 are arrange | positioned concentrically centering | focusing on centerline A1. The fan body 14 is disposed on the outer side B1 of the work clothes 34, and the belt adapter 39 is disposed on the inner side B2 of the work clothes 34. Then, the cylindrical portion 20 is caused to enter the attachment 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 main body 14 and the belt adapter 39, the relative position between the fan main body 14 and the belt adapter 39 is arbitrarily set around the center line A <b> 1 with the protrusion 46 inserted in the mounting groove 25. 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 and the fan main body 14 and the belt adapter 39 are positioned. The fan unit 38 shown in FIG. 24 is an example in which the fan body 14 and the belt adapter 39 are positioned by stopping the protrusion 46 over the protrusion 51.

  Thus, when the relative position between the fan main body 14 and the belt adapter 39 is arbitrarily changed around the center line A1, the exhaust pipe 44 is not changed without changing the circumferential position of the fan main body 14 with respect to the work clothes 34. The direction of the air discharged from the inside to the inside B2 of the work clothes 34 can be changed as shown in FIGS.

  FIG. 25 shows the belt adapter 39 with respect to the fan main body 14 so that the interval 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 is approached. An example of positioning is shown. In FIG. 26, the belt adapter 39 is positioned with respect to the fan main body 14 so that the interval between the line segments D1 indicating the directions of the air discharged from the two sets of fan units 38 increases as the distance from the collar portion 36 increases. An example is shown. Therefore, it is possible for the worker to discharge air from the exhaust pipe 44 toward an arbitrary location on the inner side B <b> 2 of the work clothes 34.

  Note that the fan unit 38 shown in FIGS. 22, 23, and 24 can also be used with the hook 41 hung on the belt 48 as shown in FIG. When the belt adapter 39 and the fan main body 14 are relatively rotated in the second direction and the protrusion 46 is retracted from the mounting groove 25, the fan main body 14 and the belt adapter 39 can be separated. As described above, the belt adapter 39 can be attached to and detached from the fan main body 14.
