[0006] Fig. 1 is a diagram showing the external appearance of a fan-equipped garment 1. As shown in Fig. 1, the fan-equipped garment 1 comprises a garment 2 and a garment fan 10 attached to the garment 2. The garment fan 10 is, for example, an axial fan. Fig. 2 is a diagram showing the external appearance of the garment 2. The back side of the garment 2 is shown in Figs. 1 and 2.

[0007] As shown in FIG. 1, the clothing fan 10 is attached to, for example, the lower part of the back surface 3 of the clothing 2. As shown in FIG. 2, a mounting hole 4 is provided in the lower part of the back surface 3 of the clothing 2 for mounting the clothing fan 10 to the clothing 2. The clothing fan 10 is attached to the mounting hole 4. In this example, two mounting holes 4 are provided side by side in the lower part of the back surface 3 of the clothing 2. The clothing fan 10 is attached to each mounting hole 4. As will be described later, the clothing fan 10 is attached to the clothing 2 so as to sandwich the peripheral portion 5 of the mounting hole 4, so that the peripheral portion 5 is reinforced. Hereinafter, the clothing fan 10 may be simply referred to as the fan 10.

[0008] Each fan 10 takes in air from one side and expels the taken-in air from the other side. Each fan 10 is attached to the garment 2 so that the side that takes in air (i.e., the intake side) is located on the outside of the garment 2 and the side that expels air (i.e., the exhaust side) is located on the inside of the garment 2. As a result, in the fan-equipped garment 1, each fan 10 takes in air from the outside to the inside of the garment 2 through the attachment holes 4. The air taken into the inside of the garment 2 is exhausted to the outside of the garment 2 from the cuffs and neck of the garment 2 by the operation of each fan 10. This makes it possible to cool the body of a person wearing the garment 2. The attachment holes 4 of the garment 2 serve as intake ports for the cooling air, and the cuffs and neck of the garment 2 serve as exhaust ports for the cooling air.

[0009] The number of fans 10 attached to the garment 2 may be one, or may be three or more. Furthermore, the attachment positions of the fans 10 with respect to the garment 2 are not limited to the examples shown in FIGS.

[0010] Various structural examples of the fan 10 will be described below. When multiple fans 10 are attached to the garment 2, the multiple fans 10 may include multiple fans 10 having the same structure, or multiple fans 10 having different structures. Hereinafter, the structure of the fan 10 will be described with the side where the fan 10 takes in air as the front side and the side where the fan 10 expels air as the rear side. In addition, when the fan 10 is attached to the garment 2, the structure of the fan 10 will be described with the neck side of the garment 2 as the upper side of the fan 10 and the hem side of the garment 2 as the lower side of the fan 10.

[0011] <First structure example> 3 to 6 are diagrams showing an example of the structure of the fan 10 (sometimes referred to as fan 10A) according to this embodiment. FIG. 3 shows the fan 10A as seen from the front, and FIG. 4 shows the fan 10A as seen from the back. FIGS. 5 and 6 show the internal structure of the fan 10A. In FIGS. 5 and 6, cross sections are hatched. FIG. 5 shows the fan 10A attached to the garment 2. The left side of the garment 2 in FIG. 5 shows the outside 500 of the garment 2, and the right side of the garment 2 in FIG. 5 shows the inside 510 of the garment 2 (in other words, the side closer to the human body than the garment 2). The upper side of FIG. 5 shows the neck side of the garment 2, and the lower side of FIG. 5 shows the hem side of the garment 2. Similarly, cross sections are hatched in the diagrams showing the internal structure of the fan 10 attached to the garment 2, which will be described later, and the left and right sides of the garment 2 show the outside 500 and the inside 510 of the garment 2, respectively, and the upper and lower sides of the diagrams show the neck side and the hem side of the garment 2, respectively. Fan 10A can be attached to clothing 2, or can be used standing on a desk or the like as shown in Fig. 6. Fig. 7 is a perspective view showing an example of the appearance of fixing member 11 provided on fan 10A. Fig. 8 is a block diagram mainly showing the electrical configuration of fan 10A.

[0012] 3 to 8, fan 10A includes a main body 12 and a fixing member 11 for fixing main body 12 to clothing 2. Main body 12 includes a housing 13, blades 14, a motor 15, a circuit board 16, a battery 17, and a stand member 18 for placing fan 10A upright. Blades 14, motor 15, circuit board 16, and battery 17 are contained in housing 13. Fixing member 11 can also be said to be a member for fixing housing 13 to clothing 2.

[0013] The housing 13 is made of, for example, resin. The outer shape of the housing 13 is substantially circular when viewed from both the front and rear. The housing 13 includes a front portion 130, a rear portion 131, and a cover portion 132.

[0014] The outer shape of the front portion 130 is substantially circular when viewed from the front. The front portion 130 includes a front portion 130a, a cylindrical portion 130b, and a flange portion 130c. The front portion 130a is provided with a plurality of air intake ports 130aa. It can be said that the front portion 130a is an intake portion that takes in air outside the housing 13 into the housing 13. Hereinafter, the front portion 130a may be referred to as the intake portion 130a.

[0015] The cylindrical portion 130b is provided on the periphery of the front portion 130a so as to surround the periphery and protrude rearward from the periphery. The flange portion 130c is provided on the periphery of the front portion 130a so as to surround the front portion 130a. The flange portion 130c protrudes from the periphery of the front portion 130a in the radial direction of the front portion 130a. As shown in FIG. 3, the flange portion 130c surrounds the intake portion 130a when the fan 10A is viewed from the intake side (in other words, the front side).

[0016] The outer shape of the rear portion 131 is substantially circular when viewed from the rear side. The rear portion 131 includes a back portion 131a and a cylindrical portion 131b. The cylindrical portion 131b is provided on the periphery of the rear portion 131a so as to surround the periphery and protrude from the periphery to the front side. The rear portion 131a and the cylindrical portion 131b are provided with a plurality of exhaust ports 131c. The rear portion 131a and the cylindrical portion 131b can be said to be exhaust portions that exhaust air to the outside of the housing 13. The plurality of exhaust ports 131c are provided to avoid the center of the rear portion 131a. The cylindrical portion 130b of the front portion 130 and the cylindrical portion 131b of the rear portion 131 are connected to each other and form a cylindrical peripheral wall portion (in other words, a side portion) 135 of the entire housing 13. When the blade portion 14 rotates, air is taken into the housing 13 through the air intake port 130aa, and the air taken into the housing 13 is exhausted to the outside of the housing 13 through the air exhaust port 131c.

[0017] A male screw portion 130bb is formed on the outer peripheral surface of the cylindrical portion 130b of the front portion 130, which is screwed with a female screw portion 110a (described later) of the fixing member 11. A recess 130ab is provided on the outer surface (in other words, the front surface) of the front portion 130a. The motor 15, the circuit board 16, and the battery 17 are fixed to the recess 130ab. A plurality of air intakes 130aa are provided in the front portion 130a except for the portion where the recess 130ab is formed. A protrusion 130ac corresponding to the recess 130ab is provided on the inner surface (in other words, the rear surface) of the front portion 130a. The protrusion 130ac protrudes rearward. A holding portion 130f that holds the stand member 18 is provided on the lower portion of the front surface of the flange portion 130c. The stand member 18 can be rotated by the user with the holding portion 130f as a base point.

[0018] The cover part 132 is attached to the front part 130a so as to cover the recess 130ab. As a result, the motor 15, the circuit board 16, and the battery 17 in the recess 130ab are covered by the cover part 132. In the housing 13, the recess 130ab and the cover part 132 covering it form an accommodation space 133 for accommodating the motor 15, the circuit board 16, and the battery 17. In the accommodation space 133, the circuit board 16 is disposed so as to face the motor 15. There is no member constituting the housing 13 between the circuit board 16 and the motor 15. The battery 17 is located below the circuit board 16. The cover part 132 includes a first part 132a that covers the circuit board 16 and a second part 132b that covers the battery 17. The second part 132b is curved outward in accordance with the outer shape of the battery 17.

[0019] The front portion 130 and the rear portion 131 form an accommodation space 134 that accommodates the blade portion 14. The blade portion 14 includes a plurality of blades 140 and a connecting portion 141 that connects the plurality of blades 140. The connecting portion 141 is tubular with one end substantially closed, and covers the protruding portion 130ac of the front portion 130a. The rotating shaft 150 of the motor 15 in the recess 130ab extends to the outside of the protruding portion 130ac and is connected to the connecting portion 141 of the blade portion 14. When the rotating shaft 150 of the motor 15 rotates, the blade portion 14 rotates accordingly.

[0020] The motor 15 is, for example, a DC motor. The motor 15 is driven by a circuit board 16. The motor 15 is electrically connected to the circuit board 16 by a lead wire 19. The battery 17 supplies power to the circuit board 16. The battery 17 is, for example, a cylindrical battery. The battery 17 may be a rechargeable secondary battery or a non-rechargeable primary battery. The battery 17 and the circuit board 16 are electrically connected by a lead wire.

[0021] 8, the circuit board 16 includes a board 160, a control unit 161, a display unit 162, and an operation unit 163. The control unit 161, the display unit 162, and the operation unit 163 are mounted on the board 160.

[0022] The control unit 161 can also be called a control circuit. The control unit 161 drives the motor 15 based on the power supplied from the battery 17. The control unit 161 can rotate the motor 15 or stop the rotation of the motor 15. The control unit 161 can also control the rotation speed of the motor 15. For example, the control unit 161 can control the rotation speed of the motor 15 by changing the voltage applied to the motor 15. The air volume of the fan 10A changes as the rotation speed of the motor 15 changes. The control unit 161 can set the air volume of the fan 10A to three levels, for example, "large", "medium", and "small", by controlling the motor 15. The air volume setting of the fan 10A may be set to two levels, or may be set to four or more levels.

[0023] All or some of the functions of control unit 161 may be implemented by hardware circuitry that does not require software to implement the functions, and control unit 161 may include at least one processor to provide control and processing power for performing various functions, as described in more detail below.

[0024] According to various embodiments, the at least one processor may be implemented as a single integrated circuit (IC) or as multiple communicatively connected integrated circuits (ICs) and / or discrete circuits. The at least one processor may be implemented according to various known techniques.

[0025] In one embodiment, a processor includes one or more circuits or units configured to perform one or more data computation procedures or processes, for example by executing instructions stored in associated memory. In other embodiments, a processor may be firmware (e.g., discrete logic components) configured to perform one or more data computation procedures or processes.

[0026] According to various embodiments, the processor may include one or more processors, controllers, microprocessors, microcontrollers, application specific integrated circuits (ASICs), digital signal processors, programmable logic devices, field programmable gate arrays, or any combination of these devices or configurations, or other known devices and configurations, to perform the functions described below.

[0027] The display unit 162 is capable of displaying the operating state of the fan 10A and includes a plurality of light-emitting units 162a. Each light-emitting unit 162a is, for example, a light-emitting diode. The control unit 161 can cause each light-emitting unit 162a to emit light individually or stop emitting light individually. As shown in FIG. 3, the plurality of light-emitting units 162a include a plurality of light-emitting units 162aa, 162ab, and 162ac that indicate the remaining amount of the battery 17, and a plurality of light-emitting units 162ad, 162ae, and 162af that indicate the air volume of the fan 10A. The light-emitting units 162aa, 162ab, 162ac, 162ad, 162ae, and 162af are exposed from the front surface of the housing 13. Specifically, the light-emitting units 162aa, 162ab, 162ac, 162ad, 162ae, and 162af are exposed from the first portion 132a of the cover unit 132 of the housing 13. It can be said that the display unit 162 is exposed from an area of ​​the housing 13 that is visible from the intake side.

[0028] The control unit 161 can specify the remaining charge of the battery 17 based on the output voltage of the battery 17. When the remaining charge of the battery 17 is sufficient, the control unit 161 causes all of the multiple light-emitting units 162aa, 162ab, and 162ac to emit light. When the remaining charge of the battery 17 is nearly half, the control unit 161 turns on the light-emitting units 162aa and 162ab and turns off the light-emitting unit 162ac. When the remaining charge of the battery 17 is low, the control unit 161 turns on the light-emitting unit 162aa and turns off the light-emitting units 162ab and 162ac.

[0029] Furthermore, when the control unit 161 sets the airflow rate of the fan 10A to "small," it causes only the light-emitting unit 162ad out of the light-emitting units 162ad, 162e, and 162f to emit light. When the control unit 161 sets the airflow rate of the fan 10A to "medium," it causes only the light-emitting unit 162ae out of the light-emitting units 162ad, 162ae, and 162af to emit light. When the control unit 161 sets the airflow rate of the fan 10A to "large," it causes only the light-emitting unit 162af out of the light-emitting units 162ad, 162ae, and 162af to emit light.

[0030] The operation unit 163 is an operation unit for controlling the motor 15, and includes, for example, an operation button 163a. ​​The operation button 163a is, for example, a push button. As shown in FIG. 3, the operation unit 163 is exposed from the front surface of the housing 13. Specifically, the operation button 163a of the operation unit 163 is exposed from the first part 132a of the cover part 132 of the housing 13. It can be said that the operation unit 163 is exposed from an area visible from the intake side of the housing 13. The control unit 161 can identify an operation on the operation button 163a.

[0031] The operation button 163a functions as, for example, a power button. When the operation button 163a is pressed for a predetermined time or longer while the fan 10A is in a power-off state, the fan 10A enters a power-on state. On the other hand, when the operation button 163a is pressed for a predetermined time or longer while the fan 10A is in a power-on state, the fan 10A enters a power-off state. The predetermined time is set to, for example, about 1 to 2 seconds. Hereinafter, the operation of pressing the operation button 163a for a predetermined time or longer may be referred to as a long press operation.

[0032] When the fan 10A is in a power-off state, most of the functions of the control unit 161 are stopped. When the fan 10A is in a power-off state, in the control unit 161, for example, a function for identifying an operation on the operation button 163a is operated, and a function for controlling the motor 15 and the display unit 162 is stopped. Therefore, when the fan 10A is in a power-off state, the motor 15 does not rotate, and each light-emitting unit 162a of the display unit 162 does not light up. When the fan 10A changes from a power-off state to a power-on state, the motor 15 rotates and the display unit 162 displays. On the other hand, when the fan 10A changes from a power-on state to a power-off state, the rotation of the motor 15 stops, and the display of the display unit 162 is turned off. The control unit 161 can put the fan 10A into a power-off state or a power-on state.

[0033] The operation button 163a also functions as an adjustment button for adjusting the air volume of the fan 10A. When the fan 10A is in a power-on state, the air volume of the fan 10A changes when the operation button 163a is pressed for less than a predetermined time and then the pressure on the operation button 163a is released. Hereinafter, the operation of pressing the operation button 163a for less than a predetermined time and then releasing the pressure on the operation button 163a may be referred to as a short press operation.

[0034] When the air volume of fan 10A is set to "small," if the operation button 163a is pressed briefly, the control unit 161 increases the rotation speed of motor 15 to set the air volume of fan 10A to "medium." When the air volume of fan 10A is set to "medium," if the operation button 163a is pressed briefly, the control unit 161 increases the rotation speed of motor 15 to set the air volume of fan 10A to "large." When the air volume of fan 10A is set to "large," if the operation button 163a is pressed briefly, the control unit 161 decreases the rotation speed of motor 15 to set the air volume of fan 10A to "small."

[0035] The display unit 162 may include a segment-type or dot-matrix-type display unit instead of or in addition to the light-emitting unit 162a. In this case, the display unit 162 may include a liquid crystal display panel or an organic EL (Electroluminescence) panel.

[0036] Operation unit 163 may include a plurality of operation buttons 163a. ​​In addition, when display unit 162 includes a dot-matrix display unit, operation unit 163 may include software buttons displayed on the dot-matrix display unit instead of or in addition to operation buttons 163a.

[0037] The fixing member 11 is a ring-shaped member for fixing the main body portion 12 to the garment 2. The fixing member 11 includes a ring-shaped attachment portion 110 that is attached to the main body portion 12. An internal thread portion 110a that screws into an external thread portion 130bb of the front portion 130 of the housing 13 is provided on the inner circumferential surface of the attachment portion 110. Furthermore, the fixing member 11 includes a flange portion 111 that protrudes radially from the outer circumferential surface of the attachment portion 110 so as to surround the outer circumferential surface of the attachment portion 110. The flange portion 111 is provided at the front end of the outer circumferential surface of the attachment portion 110.

[0038] The stand member 18 is a support member capable of supporting the housing 13 and for placing the fan 10A upright. As shown in FIG. 3, the stand member 18 is a rod-like member having a substantially U-shape. The stand member 18 includes a held portion 180 that is held by the holding portion 130f of the housing 13. The held portion 180 is linear. Furthermore, the stand member 18 includes a pair of support portions 181 that can support the housing 13 when the fan 10A is placed upright as shown in FIG. 6. The pair of support portions 181 extend substantially curvedly from both ends of the held portion 180 in the longitudinal direction so as to face each other. The stand member 18 is rotatable around the longitudinal direction of the held portion 180, starting from the held portion 180 held by the housing 13.

[0039] When the fan 10A is attached to the clothing 2, the attitude of the stand member 18 is set so that the pair of support parts 181 face the front surface of the housing 13, as shown in Figures 3 and 5. On the other hand, when the fan 10A is placed upright on a desk or the like, the attitude of the stand member 18 is set so that the pair of support parts 181 are significantly separated from the front surface of the housing 13, as shown in Figure 6. When the fan 10A is placed upright, as shown in Figure 6, the pair of support parts 181 support the housing 13 so that it does not fall over. Arrow 9A shown in Figure 6 indicates the direction in which air flows when the blades 14 of the fan 10A rotate.

[0040] When the fan 10A having the above configuration is attached to the mounting hole 4 of the garment 2, first, the housing 13 of the main body 12 is inserted into the mounting hole 4 from the outside 500 of the garment 2. At this time, the housing 13 is inserted into the mounting hole 4 from the rear portion 131 side. When the housing 13 is inserted into the mounting hole 4 from the rear portion 131 side, the flange portion 130c of the front portion 130 abuts against the surface of the outside 500 of the periphery 5 of the mounting hole 4 of the garment 2 without passing through the mounting hole 4.

[0041] Next, the fixing member 11 is attached to the housing 13 from the inside 510 of the garment 2 so that the flange portion 111 of the fixing member 11 abuts against the surface of the inside 510 of the peripheral portion 5 of the garment 2. Specifically, the fixing member 11 is attached to the front portion 130 so that the female screw portion 110a on the inner peripheral surface of the fixing member 11 is screwed into the male screw portion 130bb on the outer peripheral surface of the cylindrical portion 130b protruding to the inside 510 of the garment 2 while the flange portion 111 abuts against the surface of the inside 510 of the peripheral portion 5. Then, the fixing member 11 is tightened clockwise as viewed from the inside 510 of the garment 2, so that the flange portion 130c of the front portion 130 and the flange portion 111 of the fixing member 11 sandwich the peripheral portion 5 of the garment 2. In this way, the fan 10A is fixed to the garment 2. When the blades 14 of the fan 10A fixed to the garment 2 rotate, air from the outside 500 of the garment 2 is taken into the inside 510 of the garment 2 through the air inlet 130aa and the air outlet 131c.

[0042] On the other hand, when the fan 10A is removed from the garment 2, the fixing member 11 is rotated counterclockwise when viewed from the inside 510 of the garment 2, and the fixing member 11 is removed from the housing 13. Then, the housing 13 is taken out of the attachment hole 4.

[0043] It should be noted that the fan 10A does not necessarily have to include the stand member 18 and the holder 130f that holds it.

[0044] In this way, in this example, since the battery 17 is located inside the housing 13, the wiring extending from the battery 17 (in this example, the lead wire connecting the battery 17 and the circuit board 16) can be shortened. This reduces the possibility of the wiring being damaged. As a result, it reduces the possibility of malfunction of the fan 10A.

[0045] Furthermore, in this example, since a cable for connecting the battery and the fan main body is not required, the fan 10A can be easily attached to the garment 2.

[0046] In this example, the operation unit 163 is exposed from an area visible from the intake side of the housing 13. Therefore, the operation unit 163 can be operated from the outside 500 of the garment 2. This makes it easier for the user to operate the operation unit 163.

[0047] In this example, the display unit 162 is exposed from an area visible from the intake side of the housing 13. Therefore, the display of the display unit 162 is visible from the outside 500 of the garment 2. This makes it easier for the user to check the display of the display unit 162.

[0048] In this example, when fan 10A is viewed from the intake side (in other words, the front side), as shown in Fig. 3, operation unit 163 is located inside the outer shape of flange portion 130c of housing 13. This makes it possible to reduce the size of fan 10A when viewed from the intake side.

[0049] Furthermore, in this example, when fan 10A is viewed from the intake side, operation portion 163 overlaps with blade portion 14. This makes it possible to reduce the size of fan 10A when viewed from the intake side.

[0050] 3, when fan 10A is viewed from the intake side, display unit 162 is located inside the outer shape of flange portion 130c of housing 13. This makes it possible to reduce the size of fan 10A when viewed from the intake side.

[0051] Furthermore, in this example, when fan 10A is viewed from the intake side, display unit 162 overlaps with blade unit 14. This makes it possible to reduce the size of fan 10A when viewed from the intake side.

[0052] In this example, when fan 10A is viewed from the intake side, battery 17 covered by cover portion 132 is located inside the outer shape of flange portion 130c. This makes it possible to reduce the size of fan 10A when viewed from the intake side.

[0053] Furthermore, in this example, when fan 10A is viewed from the intake side, battery 17 overlaps blade portion 14. This allows the size of fan 10A to be reduced when viewed from the intake side.

[0054] Furthermore, in this example, since an operation unit 163 is provided for each fan 10, the user can control each fan 10 individually.

[0055] If battery 17 is a rechargeable secondary battery, fan 10A may be provided with a charging terminal for supplying a charging voltage to battery 17. The charging terminal may be a Universal Serial Bus (USB) terminal or a terminal for connecting to an AC adapter. Similarly, a charging terminal may be provided on fan 10 (described below) having a different structure from fan 10A.

[0056] <Second structure example> 9 to 12 are diagrams showing an example of the appearance of the fan 10 according to this example (sometimes referred to as fan 10B). FIG. 9 shows the fan 10B as seen from the front. FIGS. 10 and 11 show the fan 10B as seen from the rear. FIG. 12 is a diagram showing the internal structure of fan 10B. FIG. 12 shows fan 10B attached to clothing 2.

[0057] 9 to 12, fan 10B includes a main body 22 and the above-mentioned fixing member 11 for fixing main body 22 to clothing 2. Main body 22 includes a housing 23, and the above-mentioned blades 14, motor 15, circuit board 16, and battery 17. Blades 14, motor 15, circuit board 16, and battery 17 are contained in housing 23.

[0058] Housing 23 is made of, for example, resin. Housing 23 includes a front portion 230, a rear portion 231, a first cover portion 232, and a second cover portion 233. Fig. 11 shows fan 10B with fixing member 11 and second cover portion 233 removed.

[0059] The front portion 230 includes a first portion 2300 that covers the front surface of the blade portion 14, and a second portion 2310 that is located below the first portion 2300. A plurality of air intakes 2301a are formed in the first portion 2300, and no air intakes are formed in the second portion 2310. The first portion 2300 is connected to the rear portion 231, and together with the rear portion 231 forms an accommodation space 237 that accommodates the blade portion 14. The second portion 2310 is connected to the second cover portion 233, and together with the second cover portion 233 forms an accommodation space 236 that accommodates the circuit board 16 and the battery 17.

[0060] The outer shape of the first portion 2300 is substantially circular when viewed from the front side. The first portion 2300 includes a front portion 2301 in which multiple intake ports 2301a are formed, a cylindrical portion 2302, and a flange portion 2303. It can be said that the front portion 2301 is an intake portion that takes air outside the housing 23 into the housing 23. The multiple intake ports 2301a are provided in the front portion 2301, avoiding its central portion. Hereinafter, the front portion 2301 may be referred to as the intake portion 2301.

[0061] The cylindrical portion 2302 is provided on the periphery of the front portion 2301 so as to surround the periphery and protrude rearward from the periphery. A male screw portion 2302a that screws into the female screw portion 110a of the fixing member 11 is formed on the outer circumferential surface of the cylindrical portion 2302. The flange portion 2303 is provided on the periphery of the front portion 2301 so as to substantially surround the front portion 2301. The flange portion 2303 protrudes from the periphery of the front portion 2301 in the radial direction of the front portion 2301.

[0062] The second portion 2310 extends downward from the lower portion of the flange portion 2303. The circuit board 16 and the battery 17 are fixed to the second portion 2310. The battery 17 is located below the circuit board 16. The second portion 2310 includes a board side portion 2311 to which the circuit board 16 is fixed, and a battery side portion 2312 to which the battery 17 is fixed. The front surface of the battery side portion 2312 is curved in accordance with the outer shape of the battery 17.

[0063] The outer shape of the rear portion 231 is substantially circular when viewed from the rear side. The rear portion 231 includes a back surface portion 231a and a cylindrical portion 231b. The cylindrical portion 231b is provided on the periphery of the rear portion 231a so as to surround the periphery and protrude from the periphery to the front side. The rear portion 231a and the cylindrical portion 231b are provided with a plurality of exhaust ports 231c. The rear portion 231a and the cylindrical portion 231b can be said to be exhaust portions that exhaust air to the outside of the housing 23.

[0064] Cylindrical portion 2302 of first portion 2300 and cylindrical portion 231b of rear portion 231 are connected to each other and form a cylindrical peripheral wall portion 235 that surrounds accommodation space 237. When blade portion 14 rotates, air is taken into housing 23 from intake port 2301a, and the air taken into housing 23 is exhausted to the outside of housing 23 from exhaust port 231c.

[0065] A recess 231aa is provided in the center of the outer surface of the back surface 231a of the rear portion 231. A motor 15 is fixed to the recess 231aa. A protrusion 231ab corresponding to the recess 231aa is provided on the inner surface of the back surface 231a. A connecting portion 141 of the blade portion 14 covers the protrusion 231ab. A rotating shaft 150 of the motor 15 in the recess 231aa extends to the outside of the protrusion 231ab and is connected to the connecting portion 141 of the blade portion 14. A plurality of air intakes 2301a are provided in the front surface 2301 of the first portion 2300, avoiding the portion facing the connecting portion 141 of the blade portion 14.

[0066] The first cover part 232 is attached to the back surface part 231a of the rear part 231 so as to cover the recessed part 231aa. As a result, the motor 15 inside the recessed part 231aa is covered by the first cover part 232. In the housing 23, the recessed part 231aa and the first cover part 232 covering it form an accommodation space 238 that accommodates the motor 15.

[0067] The second cover part 233 is attached to the second part 2310 of the front part 230. The second cover part 233 includes a first part 233a that covers the circuit board 16 and a second part 233b that covers the battery 17. The rear surface of the second part 233b is curved according to the outer shape of the battery 17.

[0068] 9, the light emitting portions 162aa, 162ab, 162ac, 162ad, 162ae, and 162af included in the display unit 162 of the circuit board 16 are exposed from the front surface of the board side portion 2311 of the second portion 2310. In addition, the operation button 163a included in the operation unit 163 of the circuit board 16 is exposed from the front surface of the board side portion 2311.

[0069] When the fan 10B having the above configuration is attached to the mounting hole 4 of the garment 2, first, the housing 23 of the main body 22 is inserted into the mounting hole 4 from the outside 500 of the garment 2. At this time, the housing 23 is inserted into the mounting hole 4 from the rear portion 231 side. When the housing 23 is inserted into the mounting hole 4 from the rear portion 231 side, the flange portion 2303 of the front portion 230 abuts against the surface of the outside 500 of the periphery 5 of the mounting hole 4 of the garment 2 without passing through the mounting hole 4. In addition, the second portion 2310 of the front portion 230 is located on the outside 500 of the garment 2 without passing through the mounting hole 4.

[0070] Next, the fixing member 11 is attached to the housing 23 from the inside 510 of the garment 2 so that the flange portion 111 of the fixing member 11 abuts against the surface of the inside 510 of the peripheral portion 5 of the garment 2. Specifically, the fixing member 11 is attached to the first portion 2300 of the front portion 230 so that the female thread portion 110a of the fixing member 11 is screwed into the male thread portion 2302a of the tubular portion 2302 protruding to the inside 510 of the garment 2 while the flange portion 111 abuts against the surface of the inside 510 of the peripheral portion 5. Then, the fixing member 11 is tightened clockwise as viewed from the inside 510 of the garment 2, whereby the flange portion 2303 of the front portion 230 and the flange portion 111 of the fixing member 11 sandwich the peripheral portion 5 of the garment 2. Furthermore, the first portion 233a of the second cover portion 233 and the flange portion 111 of the fixing member 11 clamp the lower portion of the peripheral edge portion 5 of the garment 2. This causes the fan 10B to be fixed to the garment 2. When the blade portion 14 of the fan 10B fixed to the garment 2 rotates, air on the outside 500 of the garment 2 is taken into the inside 510 of the garment 2 through the intake port 2031a and the exhaust port 231c.

[0071] On the other hand, when the fan 10B is removed from the garment 2, the fixing member 11 is rotated counterclockwise when viewed from the inside 510 of the garment 2, and the fixing member 11 is removed from the housing 23. Then, the housing 23 is taken out of the attachment hole 4.

[0072] In this manner, in this example, as in the first structural example, since the battery 17 is located inside the housing 23, the wiring extending from the battery 17 can be shortened. This reduces the possibility of the wiring being damaged. As a result, the possibility of malfunction of the fan 10B can be reduced.

[0073] Furthermore, in this example, since a cable for connecting the battery and the fan main body is not required, the fan 10B can be easily attached to the clothing 2.

[0074] In this example, the operation unit 163 is exposed from an area visible from the intake side of the housing 23. Therefore, the operation unit 163 can be operated from the outside 500 of the garment 2. This makes it easier for the user to operate the operation unit 163.

[0075] In this example, the display unit 162 is exposed from an area visible from the intake side of the housing 23. Therefore, the display of the display unit 162 is visible from the outside 500 of the garment 2. This makes it easier for the user to check the display of the display unit 162.

[0076] Furthermore, in this example, since an operation unit 163 is provided for each fan 10, the user can control each fan 10 individually.

[0077] Furthermore, in this example, when fan 10B is viewed from the intake side, display unit 162 is located outside intake unit 2301. This reduces the possibility that display unit 162 will obstruct the intake of air by fan 10B, thereby improving the performance of fan 10B.

[0078] Furthermore, in this example, when fan 10B is viewed from the intake side, operation unit 163 is located outside intake unit 2301. This reduces the possibility that operation unit 163 will obstruct the intake of fan 10B, thereby improving the performance of fan 10B.

[0079] In addition, in this example, when fan 10B is viewed from the intake side, battery 17 covered by second portion 2310 of housing 23 is located outside intake section 2301. This reduces the possibility that battery 17 will obstruct the intake of air by fan 10B, thereby improving the performance of fan 10B.

[0080] In this example, circuit board 16 is located below motor 15, and therefore does not have a portion facing motor 15 when viewed from the intake side. In contrast, in fan 10A according to the first structural example described above, circuit board 16 has a portion facing motor 15 when viewed from the intake side. Circuit board 16 has a portion facing motor 15, which makes it possible to reduce the size of fan 10 when viewed from the front.

[0081] <Third structure example> 13 to 16 are diagrams showing an example of the structure of the fan 10 (sometimes referred to as fan 10C) according to this embodiment. FIG. 13 shows the fan 10C as viewed from the front. FIGS. 14 and 15 show the fan 10C as viewed from the rear. FIG. 16 is a diagram showing the internal structure of the fan 10C. FIG. 16 shows the fan 10C attached to clothing 2.

[0082] 13 to 16, fan 10C includes a housing 33, and the above-mentioned blades 14, motor 15, circuit board 16, and battery 17. Blades 14, motor 15, circuit board 16, and battery 17 are accommodated in housing 33.

[0083] The housing 33 is made of, for example, resin. The housing 33 includes a front portion 330, a rear portion 331, and a cover portion 332. Figure 15 shows the fan 10C with the cover portion 332 removed.

[0084] To the rear part 331, the blades 14, the motor 15, the circuit board 16, and the battery 17 are fixed. The rear part 331 can be said to be a holding part that holds the blades 14, the motor 15, the circuit board 16, and the battery 17. The front part 330 is detachable from the rear part 331. The front part 330 functions as a fixing part for fixing the rear part 331 that holds the blades 14 etc. to the garment 2. Hereinafter, the rear part 331 may be referred to as the holding part 331. The front part 330 may be referred to as the fixing part 330.

[0085] The outer shape of the fixing part 330 is substantially circular when viewed from the front side. The fixing part 330 includes a front part 330a, a cylindrical part 330b, and a flange part 330c. The front part 330a is provided with a plurality of intake ports 330aa, avoiding the center part. The front part 330a can be said to be an intake part that takes in air outside the housing 33 into the housing 33. Hereinafter, the front part 330a may be referred to as the intake part 330a.

[0086] The cylindrical portion 330b is provided on the periphery of the front portion 330a so as to surround the periphery and protrude rearward from the periphery. A male screw portion 330bb is formed on the outer circumferential surface of the cylindrical portion 330b and is screwed with a female screw portion 3312a (described later) of the holding portion 331. The flange portion 330c is provided on the periphery of the front portion 330a so as to surround the front portion 330a. The flange portion 330c protrudes from the periphery of the front portion 330a in the radial direction of the front portion 330a.

[0087] The holder 331 includes a first holder 3310 that holds the blade 14 and the motor 15, and a second holder 3320 that holds the circuit board 16 and the battery 17. The first holder 3310 and the second holder 3320 are integrally formed.

[0088] The outer shape of the first holding portion 3310 is substantially circular when viewed from the rear side. The first holding portion 3310 includes a rear portion 3311, a cylindrical portion 3312, and a flange portion 3313. The cylindrical portion 3312 is provided on the periphery of the rear portion 3311 so as to surround the periphery and protrude from the periphery to the front side. The rear portion 3311 and the cylindrical portion 3312 are provided with a plurality of exhaust ports 3314. The rear portion 3311 and the cylindrical portion 3312 can be said to be exhaust portions that exhaust air to the outside of the housing 33. A female screw portion 3312a that screws into the male screw portion 330bb of the fixing portion 330 is formed on the inner circumferential surface of the cylindrical portion 3312. Cylindrical portion 330b of fixing portion 330 and cylindrical portion 3312 of holding portion 331 are connected to each other by screwing male thread portion 330bb and female thread portion 3312a together, and form a cylindrical peripheral wall portion (in other words, a side surface portion) 335 of the entire housing 33. When vane portion 14 rotates, air is taken into housing 33 from intake port 330aa, and the air taken into housing 33 is exhausted to the outside of housing 33 from exhaust port 3314.

[0089] The flange portion 3313 is provided on the outer circumferential surface of the cylindrical portion 3312 so as to surround the cylindrical portion 3312. The flange portion 3313 protrudes from the outer circumferential surface of the cylindrical portion 3312 in the radial direction of the cylindrical portion 3312. The flange portion 3313 is located slightly rearward of the front end of the cylindrical portion 3312. Therefore, the flange portion 3313 is not provided at the front end portion 3312b of the cylindrical portion 3312.

[0090] A recess 3311b is provided in the center of the outer surface of the back portion 3311 of the first holding portion 3310. Motor 15 is fixed to recess 3311b. A protrusion 3311c corresponding to recess 3311b is provided on the inner surface of the back portion 3311. Cylindrical connecting portion 141 of blade portion 14 covers protrusion 3311c. Rotating shaft 150 of motor 15 in recess 3311b extends to the outside of protrusion 3311c and is connected to connecting portion 141 of blade portion 14.

[0091] The second holding portion 3320 includes a first portion 3321 in which the lead wires 19 connecting the motor 15 and the circuit board 16 are disposed, and a second portion 3322 that holds the circuit board 16 and the battery 17. The circuit board 16 and the battery 17 are fixed to the second portion 3322. The second holding portion 3320 extends from the recess 3311b of the rear portion 3311 of the first holding portion 3310 to the lower side of the cylindrical portion 3312 of the first holding portion 3310. The rear side of the second holding portion 3320 is open. The first portion 3321 is provided on the outer surface of the rear portion 3311. The upper portion of the second portion 3322 is provided on the outer surface of the rear portion 3311. The lower portion of the second portion 3322 protrudes from the cylindrical portion 3312 of the first holding portion 3310 to the lower side of the cylindrical portion 3312.

[0092] The cover portion 332 is attached to the rear portion 3311 and the second holding portion 3320 so as to cover the recess 3311b of the rear portion 3311 of the first holding portion 3310 and the rear opening of the second holding portion 3320. As a result, the motor 15 in the recess 3311b and the lead wires 19, the circuit board 16, and the battery 17 in the second holding portion 3320 are covered by the cover portion 332. The cover portion 332 includes a first portion 332a covering the motor 15, a second portion 332b covering the lead wires 19, and a third portion 332c covering the circuit board 16 and the battery 17.

[0093] 14, the light emitting units 162aa, 162ab, 162ac, 162ad, 162ae, and 162af included in the display unit 162 of the circuit board 16 are exposed from the rear surface of a portion 332cc of the third portion 332c of the cover unit 332 that faces the circuit board 16. In addition, the operation button 163a included in the operation unit 163 of the circuit board 16 is exposed from the rear surface of the portion 332cc of the third portion 332c of the cover unit 332 that faces the circuit board 16.

[0094] When the fan 10C having the above configuration is attached to the mounting hole 4 of the garment 2, first, the front end 3312b of the tubular portion 3312 of the first holding portion 3310 of the housing 33 is inserted into the mounting hole 4 from the inside 510 of the garment 2. At this time, the flange portion 3313 of the first holding portion 3310 abuts against the surface of the inside 510 of the periphery 5 of the mounting hole 4 of the garment 2 without passing through the mounting hole 4. In addition, the second portion 3322 of the second holding portion 3320 is located on the inside 510 of the garment 2 without passing through the mounting hole 4.

[0095] Next, the fixing part 330 is attached to the holding part 331 from the outside 500 of the garment 2 so that the flange part 330c of the fixing part 330 abuts against the surface of the outside 500 of the peripheral part 5 of the garment 2. Specifically, the fixing part 330 is attached to the first holding part 3310 of the holding part 331 so that the male screw part 330bb of the cylindrical part 330b of the fixing part 330 is screwed into the female screw part 3312a of the cylindrical part 3312 of the holding part 331 while the flange part 330c abuts against the surface of the outside 500 of the peripheral part 5. Then, the fixing part 330 is tightened clockwise as viewed from the outside 500 of the garment 2, whereby the flange part 330c of the fixing part 330 and the flange part 3313 of the first holding part 3310 hold the peripheral part 5 of the garment 2 in a pinched manner. Furthermore, a portion of the second holding portion 3320 located below the tubular portion 3312 of the first holding portion 3310 and the flange portion 330c of the fixing portion 330 sandwich a lower portion of the peripheral edge portion 5 of the garment 2. This fixes the fan 10C to the garment 2. When the blade portion 14 of the fan 10C fixed to the garment 2 rotates, air on the outside 500 of the garment 2 is taken into the inside 510 of the garment 2 through the intake port 330aa and the exhaust port 3314.

[0096] On the other hand, when the fan 10C is removed from the garment 2, the fixing part 330 is rotated counterclockwise when viewed from the outside 500 of the garment 2, and the fixing part 330 is removed from the holding part 331. Then, the front end 3312b of the tubular part 3312 of the holding part 331 is taken out from the attachment hole 4.

[0097] In this example, when the fan 10C is attached to the clothing 2, the operation unit 163 is located on the inside 510 of the clothing 2. Therefore, the user can operate the operation unit 163 from the inside 510 of the clothing 2. Also, in this example, the display unit 162 is located on the inside 510 of the clothing 2. Therefore, the user can view the display of the display unit 162 from the inside 510 of the clothing 2.

[0098] In this manner, in this example, as in the first structural example, the battery 17 is located inside the housing 33, and therefore the wiring extending from the battery 17 can be shortened. This reduces the possibility of the wiring being damaged. As a result, it reduces the possibility of malfunction of the fan 10C.

[0099] Furthermore, in this example, since a cable for connecting the battery and the fan main body is not required, the fan 10C can be easily attached to the clothing 2.

[0100] Furthermore, in this example, since an operation unit 163 is provided for each fan 10, the user can control each fan 10 individually.

[0101] Furthermore, in this example, the fixing part 330 is attached to the holding part 331 from the outside 500 of the garment 2. On the other hand, if the fixing member 11 is attached to the housing from the inside 510 of the garment 2 as in the first and second structural examples described above, the user's body may get in the way when wearing the garment 2, making it difficult for the user to attach the fixing member 11 to the housing from the inside 510 of the garment 2. In this example, the user can attach the fixing part 330 to the holding part 331 from the outside 500 of the garment 2, making it easier to attach the fan 10C to the garment 2 even when wearing the garment 2.

[0102] Furthermore, in this example, since the operating unit 163 is located on the inside 510 of the garment 2, the possibility of the operating unit 163 being damaged can be reduced.

[0103] Furthermore, in this example, since the display unit 162 is located on the inside 510 of the garment 2, the possibility of the display unit 162 being damaged can be reduced.

[0104] Furthermore, in this example, since the battery 17 is located on the inside 510 of the garment 2, the possibility of the battery 17 being damaged can be reduced.

[0105] In addition, in this example, when the fan 10C is viewed from the intake side, the battery 17 covered by the second holding portion 3320 of the housing 33 is located outside the intake portion 330a. This reduces the possibility that the battery 17 will obstruct the intake of air by the fan 10C, thereby improving the performance of the fan 10C.

[0106] Furthermore, in this example, when fixed part 330 is attached to holding part 331, it covers the front surface of blade part 14. Therefore, by removing fixed part 330 from holding part 331, the front surface of blade part 14 is no longer covered by the member that constitutes housing 33. This makes it easier to clean blade part 14. For example, when fan-equipped garment 1 is used in a work environment where dust is generated, dust may adhere to blade part 14. By removing fixed part 330 from holding part 331, dust that has adhered to blade part 14 can be easily removed.

[0107] <Fourth structure example> 17 to 22 are diagrams showing an example of the structure of the fan 10 according to this embodiment (sometimes referred to as fan 10D). FIG. 17 shows the fan 10D as viewed from the front, and FIGS. 18 and 19 show the fan 10D as viewed from the rear. FIGS. 20 to 22 are diagrams showing the internal structure of the fan 10D. FIG. 20 shows the fan 10D attached to clothing 2. The fan 10D can be attached to clothing 2, or can be used by standing it up on a desk or the like as shown in FIG. 21, or can be used by hanging it from a rod- or hook-shaped member 91 as shown in FIG. 22.

[0108] 17 to 22, fan 10D includes a main body 42 and a fixing member 21 for fixing main body 42 to clothing 2. Main body 42 includes a housing 43, the above-mentioned blades 14, motor 15, circuit board 16, and battery 17, and a ring-shaped support member 28. Blades 14, motor 15, circuit board 16, and battery 17 are contained in housing 43.

[0109] The housing 43 is made of, for example, resin. The housing 43 includes a front portion 430, a rear portion 431, a first holding portion 432 that holds the motor 15, the circuit board 16, and the battery 17, a cover portion 433, and a second holding portion 434 that holds the support member 28. Fig. 19 shows the fan 10D with the rear portion 431 removed.

[0110] The front portion 430 includes a front portion 430a, a cylindrical portion 430b, and a flange portion 430c. The outer shape of the front portion 430a is substantially circular when viewed from the front side. The front portion 430a is provided with a plurality of air intake ports 430aa. It can be said that the front portion 430a is an intake portion that takes in air outside the housing 43 into the housing 43. Hereinafter, the front portion 430a may be referred to as the intake portion 430a.

[0111] The cylindrical portion 430b is provided on the periphery of the front portion 430a so as to surround the periphery and protrude rearward from the periphery. The cylindrical portion 430b includes a cylindrical front portion 430ba and a cylindrical rear portion 430bb. The rear portion 430bb has a gap at the lower portion, and the rear portion 430bb is not completely cylindrical. A male screw portion 430baa is formed on the outer circumferential surface of the front portion 430ba, which is screwed with a female screw portion 210a (described later) of the fixing member 21. The flange portion 430c is provided on the periphery of the front end portion of the rear portion 430bb of the cylindrical portion 430b so as to surround the cylindrical portion 430b. The flange portion 430c protrudes in the radial direction of the cylindrical portion 430b from the periphery of the rear portion 430bb of the cylindrical portion 430b.

[0112] The outer shape of the rear portion 431 is substantially circular when viewed from the rear side. The rear portion 431 includes a rear portion 431a and a cylindrical portion 431b. The cylindrical portion 431b is provided on the peripheral edge of the rear portion 431a so as to surround the peripheral edge and protrude from the peripheral edge to the front side. The rear portion 431a and the cylindrical portion 431b are provided with a plurality of exhaust ports 431c. The plurality of exhaust ports 431c are provided to avoid the center portion of the rear portion 431a. The cylindrical portion 430b of the front portion 430 and the cylindrical portion 431b of the rear portion 431 are connected to each other. The cylindrical portion 430b, the cylindrical portion 431b, and a third portion 432c (described later) of the first holding portion 432 constitute a cylindrical peripheral wall portion (in other words, a side portion) 435 of the entire housing 43. In this example, the blades 14, the motor 15, and the circuit board 16 are present in an accommodation space 436 surrounded by a peripheral wall portion 435. When the blades 14 rotate, air is taken into the housing 43 from the intake port 430aa, and the air taken into the housing 43 is exhausted to the outside of the housing 43 from the exhaust port 431c.

[0113] The first holding portion 432 includes a first portion 432a that holds the motor 15 and the circuit board 16, a second portion 432b that holds the battery 17, and a third portion 432c that constitutes a part of the lower portion of the peripheral wall portion 435. The front side of the first holding portion 432 is open. The third portion 432c is located in a gap below the rear portion 430bb of the cylindrical portion 430b of the front portion 430, and is connected to the rear portion 430bb so as to fill the gap.

[0114] The first portion 432a is located within the storage space 436. The first portion 432a extends downward from the center when the storage space 436 surrounded by the peripheral wall portion 435 is viewed from the front or rear, to the third portion 432c which is a part of the peripheral wall portion 435. The first portion 432a includes a motor holding portion 432aa which holds the motor 15 and protrudes rearward. The connecting portion 141 of the blade portion 14 covers the motor holding portion 432aa. The rotating shaft 150 of the motor 15 extends to the outside of the motor holding portion 432aa and is connected to the connecting portion 141 of the blade portion 14. The second portion 432b is connected to the third portion 432c and is located below the peripheral wall portion 435. The second portion 432b is curved rearward in accordance with the shape of the battery 17.

[0115] The cover portion 433 is integrally formed with the front portion 430. The cover portion 433 includes a first portion 433a that closes the front opening of the first portion 432a of the first holding portion 432, and a second portion 433b that closes the front opening of the second portion 432b of the first holding portion 432. The first portion 433a covers the motor 15 and the circuit board 16 held by the first portion 432a, and the second portion 433b covers the battery 17 held by the second portion 432b. The first portion 433a extends downward from the center of the front portion 430a to the cylindrical portion 430b of the front portion 430. The second portion 433b is connected to the cylindrical portion 430b and exists below the cylindrical portion 430b. The upper end of the second portion 433b constitutes a part of the flange portion 430c.

[0116] 17, the light emitting portions 162aa, 162ab, 162ac, 162ad, 162ae, and 162af included in the display unit 162 of the circuit board 16 are exposed from the front surface of the first portion 433a of the cover portion 433. In addition, the operation button 163a included in the operation unit 163 of the circuit board 16 is exposed from the front surface of the first portion 433a.

[0117] The fixing member 21 for fixing the main body 42 to the garment 2 has a structure similar to that of the fixing member 11 described above, and is a ring-shaped member. The fixing member 21 is detachable from the housing 43. The fixing member 21 includes a ring-shaped attachment portion 210 attached to the housing 43 of the main body 42. The inner peripheral surface of the attachment portion 210 is provided with a female screw portion 210a that screws into the male screw portion 430baa of the front portion 430 of the housing 43. Furthermore, the fixing member 21 includes a flange portion 211 that protrudes in the radial direction of the fixing member 21 from the outer peripheral surface of the attachment portion 210 so as to surround the outer surface of the attachment portion 210. The flange portion 211 is provided at the rear end of the outer surface of the attachment portion 210.

[0118] The support member 28 is held by a second holding portion 434 provided on the front surface of the cover portion 433. The second holding portion 434 is integrally formed with the cover portion 433. The second holding portion 434 is located below the center of the front surface portion 430a. As shown in FIG. 21, when the fan 10D is used in an upright position, the support member 28 supports the fan 10D so that it does not fall over. The support member 28 can be said to be a support member for placing the fan 10D in an upright position, capable of supporting the housing 43. On the other hand, as shown in FIG. 22, when the fan 10D is used in a suspended position, the support member 28 functions as a hanging member for hanging the fan 10D from a rod-shaped member, a hook-shaped member, or the like.

[0119] The support member 28 has two linear portions 28a and 28b facing each other, and two curved portions 28c and 28d facing each other. The curved portion 28c curves outward and extends from one end of the linear portion 28a in the longitudinal direction to one end of the linear portion 28b in the longitudinal direction. The curved portion 28c curves outward and extends from the other end of the linear portion 28a in the longitudinal direction to the other end of the linear portion 28b in the longitudinal direction. The second holding portion 434 holds the linear portion 28a of the support member 28. The support member 28 is rotatable around the longitudinal direction of the linear portion 28a, starting from the linear portion 28a held by the second holding portion 434.

[0120] When the fan 10D is attached to the garment 2, the support member 28 is set in a position such that the support member 28 faces the front surface of the front portion 430a of the housing 43, as shown in FIGS.

[0121] When fan 10D is placed upright on a desk or the like, as shown in Fig. 21, support member 28 is set at a position where straight portion 28b and curved portions 28c and 28d are far away from the front surface of housing 13. Then, straight portion 28b abuts against mounting surface 90 on which fan 10D is placed, so that housing 43 is supported by support member 28 so as not to fall over. Fan 10D is placed on mounting surface 90 with the battery 17 side facing mounting surface 90. Arrow 9B shown in Fig. 21 indicates the direction in which air flows when blades 14 rotate.

[0122] When fan 10D is suspended, support member 28 is hooked onto rod- or hook-shaped member 91, as shown in Fig. 22. Arrow 9C shown in Fig. 22 indicates the direction in which air flows when blade portion 14 rotates.

[0123] When the fan 10D having the above configuration is attached to the attachment hole 4 of the garment 2, first, the front portion 430ba of the tubular portion 430b of the front portion 430 of the housing 43 is inserted into the attachment hole 4 from the inside 510 of the garment 2. At this time, the flange portion 430c of the front portion 430 abuts against the surface of the inside 510 of the periphery 5 of the attachment hole 4 of the garment 2 without passing through the attachment hole 4. In addition, the second portion 433b of the cover portion 433 that covers the battery 17 is located on the inside 510 of the garment 2 without passing through the attachment hole 4. Therefore, the battery 17 is located on the inside 510 of the garment 2.

[0124] Next, the fixing member 21 is attached to the housing 43 from the outside 500 of the garment 2 so that the flange portion 211 of the fixing member 21 abuts against the surface of the outside 500 of the peripheral portion 5 of the garment 2. Specifically, the fixing member 21 is attached to the front portion 430 so that the female screw portion 210a of the fixing member 21 is screwed into the male screw portion 430baa of the front portion 430ba of the cylindrical portion 430b while the flange portion 211 abuts against the surface of the outside 500 of the peripheral portion 5. Then, the fixing member 21 is tightened clockwise as viewed from the outside 500 of the garment 2, whereby the flange portion 211 of the fixing member 21 and the flange portion 430c of the front portion 430 hold the peripheral portion 5 of the garment 2 between them. As a result, the fan 10D is fixed to the garment 2. When the blades 14 of the fan 10D fixed to the garment 2 rotate, air from the outside 500 of the garment 2 is taken into the inside 510 of the garment 2 through the air intake 430aa and the air exhaust 431c.

[0125] On the other hand, when the fan 10D is removed from the garment 2, the fixing member 21 is rotated counterclockwise when viewed from the outside 500 of the garment 2, and the fixing member 21 is removed from the front part 430. Then, the front part 430ba of the cylindrical portion 430b of the front part 430 is taken out from the attachment hole 4.

[0126] In this manner, in this example, as in the first structural example, the battery 17 is located inside the housing 43, and therefore the wiring extending from the battery 17 can be shortened. This reduces the possibility of the wiring being damaged. As a result, it reduces the possibility of malfunction of the fan 10D.

[0127] Furthermore, in this example, since a cable for connecting the battery and the fan main body is not required, the fan 10D can be easily attached to the garment 2.

[0128] In addition, in this example, since the operation unit 163 can be operated from the outside 500 of the garment 2, the user can easily operate the operation unit 163.

[0129] Furthermore, in this example, the display on the display unit 162 is visible from the outside 500 of the garment 2, making it easier for the user to check the display on the display unit 162.

[0130] Furthermore, in this example, since an operation unit 163 is provided for each fan 10, the user can control each fan 10 individually.

[0131] Furthermore, in this example, the housing 43 is attached to the garment 2 from the inside 510 of the garment 2. The fixing member 21 is attached to the housing 43 from the outside 500 of the garment 2. Therefore, the user can attach the fixing member 21 to the housing 43 from the outside of the garment 2. This makes it easy for the user to attach the fan 10D to the garment 2 even while wearing the garment 2.

[0132] Furthermore, in this example, since the battery 17 is located on the inside 510 of the garment 2, the possibility of the battery 17 being damaged can be reduced.

[0133] In this example, when fan 10D is viewed from the intake side, operation unit 163 is located inside the outer shape of flange portion 211 that surrounds intake portion 430a, as shown in Fig. 17. This makes it possible to reduce the size of fan 10D when viewed from the intake side.

[0134] Furthermore, in this example, when fan 10D is viewed from the intake side, operation unit 163 overlaps with blade unit 14. This makes it possible to reduce the size of fan 10D when viewed from the intake side.

[0135] 17, when fan 10D is viewed from the intake side, display unit 162 is located inside the outline of flange portion 211. This makes it possible to reduce the size of fan 10D when viewed from the intake side.

[0136] Furthermore, in this example, when fan 10D is viewed from the intake side, display unit 162 overlaps with blade unit 14. This makes it possible to reduce the size of fan 10D when viewed from the intake side.

[0137] In addition, in this example, when fan 10D is viewed from the intake side, battery 17 covered by cover portion 433 is located outside intake portion 430a. This reduces the possibility that battery 17 will obstruct the intake of air by fan 10D, thereby improving the performance of fan 10D.

[0138] <Fifth structure example> 23 to 27 are diagrams showing an example of the structure of the fan 10 according to this example (sometimes referred to as fan 10E). Figs. 23 and 24 show the fan 10E as viewed from the front. Figs. 25 and 26 show the fan 10D as viewed from the rear. Fig. 27 is a diagram showing the internal structure of fan 10D.

[0151] When the fan 10E having the above configuration is attached to the attachment hole 4 of the garment 2, first, the rear part 5320 is attached to the front part 5310 such that the male thread portion 5322a of the cylindrical part 5322 of the rear part 5320 (in other words, the cover part 5320) is screwed into the female thread portion 5313bb ​​of the rear part 5313b of the intermediate cylindrical part 5313 of the front part 5310. Then, the rear part 5320 is fastened clockwise as viewed from the rear side, thereby fixing the rear part 5320 to the front part 5310. In this way, the holding part 531 is prepared.

[0152] Next, the front portion 5313a of the intermediate cylindrical portion 5313 of the holding portion 531 is inserted into the attachment hole 4 from the inside 510 of the garment 2. At this time, the flange portion 5314 of the holding portion 531 abuts against the surface of the inside 510 of the periphery 5 of the attachment hole 4 of the garment 2 without passing through the attachment hole 4. In addition, the second portion 5312b of the cover portion 5312 that covers the battery 17 is located on the inside 510 of the garment 2 without passing through the attachment hole 4. Therefore, the battery 17 is located on the inside 510 of the garment 2.

[0153] Next, the fixing part 530 is attached to the holding part 531 from the outside 500 of the garment 2 so that the flange part 530c of the fixing part 530 abuts against the surface of the outside 500 of the peripheral part 5 of the garment 2. Specifically, the fixing part 530 is attached to the front part 5310 of the holding part 531 so that the female screw part 530bb of the fixing part 530 is screwed into the male screw part 5313aa of the front part 5313a of the intermediate cylindrical part 5313 of the holding part 531 while the flange part 530c abuts against the surface of the outside 500 of the peripheral part 5. Then, the fixing part 530 is tightened clockwise as viewed from the outside 500 of the garment 2, so that the flange part 530c of the fixing part 530 and the flange part 5314 of the holding part 531 hold the peripheral part 5 of the garment 2 between them. This fixes the fan 10E to the garment 2. When the blade portion 14 of the fan 10E fixed to the garment 2 rotates, air from the outside 500 of the garment 2 is taken into the inside 510 of the garment 2 through the air intake 530aa and the air exhaust 5323.

[0154] On the other hand, when the fan 10E is removed from the garment 2, the fixing part 530 is rotated counterclockwise when viewed from the outside 500 of the garment 2, and the fixing part 530 is removed from the holding part 531. Then, the front part 5313a of the intermediate cylindrical part 5313 of the holding part 531 is taken out from the attachment hole 4.

[0155] In this manner, in this example, similarly to the first structural example, since the battery 17 is located inside the housing 53, the wiring extending from the battery 17 can be shortened. This reduces the possibility of the wiring being damaged. As a result, it reduces the possibility of malfunction of the fan 10E.

[0156] Furthermore, in this example, since a cable for connecting the battery and the fan main body is not required, the fan 10E can be easily attached to the garment 2.

[0157] In this example, the operation unit 163 is exposed from a region visible from the intake side of the housing 53. Specifically, the operation unit 163 is visible from the front side through the opening 530ab of the fixing part 530. Thus, the operation unit 163 can be operated from the outside 500 of the garment 2. This makes it easier for the user to operate the operation unit 163.

[0158] Moreover, in this example, the display unit 162 is exposed from an area visible from the intake side of the housing 53. Specifically, the display unit 162 is visible from the front side through the opening 530ab of the fixing part 530. Thus, the display of the display unit 162 is visible from the outside 500 of the garment 2. This makes it easier for the user to check the display of the display unit 162.

[0159] 23, when fan 10E is viewed from the intake side, operation unit 163 is located inside the outer shape of flange portion 530c of housing 53. This makes it possible to reduce the size of fan 10D when viewed from the intake side.

[0160] Furthermore, in this example, when fan 10D is viewed from the intake side, operation unit 163 overlaps with blade unit 14. This makes it possible to reduce the size of fan 10D when viewed from the intake side.

[0161] 23, when fan 10D is viewed from the intake side, display unit 162 is located inside the outer shape of flange portion 530c of housing 53. This makes it possible to reduce the size of fan 10D when viewed from the intake side.

[0162] Furthermore, in this example, when fan 10D is viewed from the intake side, display unit 162 overlaps with blade unit 14. This makes it possible to reduce the size of fan 10D when viewed from the intake side.

[0163] Furthermore, in this example, since an operation unit 163 is provided for each fan 10, the user can control each fan 10 individually.

[0164] 27, in this example, operation unit 163 is located closer to the exhaust side (in other words, rear side) than intake unit 530a. This allows the total area of ​​multiple intake ports 530aa of intake unit 530a to be larger than that of fan 10D described above. This improves the performance of fan 10D.

[0165] 27, in this example, display unit 162 is located closer to the exhaust side than intake unit 530a. This allows the total area of ​​multiple intake ports 530aa of intake unit 530a to be larger than that of fan 10D described above. This improves the performance of fan 10D.

[0166] Furthermore, in this example, the holder 531 that holds the blades 14 and the like is attached to the garment 2 from the inside 510 of the garment 2. The fixed part 530 is attached to the holder 531 from the outside 500 of the garment 2. Therefore, the user can attach the fixed part 530 to the holder 531 from the outside of the garment 2. This makes it easy for the user to attach the fan 10E to the garment 2 even while wearing the garment 2.

[0167] Furthermore, in this example, since the battery 17 is located on the inside 510 of the garment 2, the possibility of the battery 17 being damaged can be reduced.

[0168] Furthermore, in this example, when fixed portion 530 is attached to holding portion 531, it covers the front surfaces of blade portions 14. Therefore, by removing fixed portion 530 from holding portion 531, the front surfaces of blade portions 14 are no longer covered by the members that constitute housing 53. This makes it easier to clean blade portions 14.

[0169] In this example, cover portion 5320 that covers the rear surface of blade portion 14 is removable. Therefore, by removing cover portion 5320, the rear surface of blade portion 14 is no longer covered by the member that constitutes housing 53. This makes it easier to clean blade portion 14.

[0170] In addition, in this example, when the fan 10E is viewed from the intake side, the battery 17 covered by the cover portion 5312 is located outside the intake portion 530a. This reduces the possibility that the battery 17 will obstruct the intake of the fan 10E. This improves the performance of the fan 10E.

[0171] <Sixth Structure Example> FIG. 28 is a diagram showing an example of the internal structure of the fan 10 (sometimes referred to as fan 10F) according to this embodiment. FIG. 28 shows the fan 10F attached to the garment 2. As shown in FIG. 28, the fan 10F includes a main body 62, the fixing member 11, a battery device 65, an attachment portion 66 for attaching the battery device 65 to the main body 62, a retaining ring 67, and a cable 68 for electrically connecting the battery device 65 and the main body 62. The battery device 65 is fixed to the main body 62 using the attachment portion 66 and the retaining ring 67. The main body 62 includes a housing 63, the blades 14 and the motor 15, and a connector 64 to which the cable 68 is connected. The lead wire 19 extending from the motor 15 is connected to the connector 64. FIG. 29 is a perspective view showing an example of the structure of the main body 62 when the main body 62 is viewed obliquely from the rear. FIG. 30 is a plan view showing an example of the structure of the housing 63 when the housing 63 is viewed from the rear. Fig. 31 is a plan view showing an example of the structure of the battery device 65 and the mounting portion 66 when viewed from the front side of the battery device 65 and the mounting portion 66. Note that in Fig. 28, the shape of the main body portion 62 is shown in a simplified manner compared to Figs. 29 and 30.

[0172] The front portion 630 includes a front portion 630a, a cylindrical portion 630b, and a flange portion 630c. A plurality of intake ports 630aa are provided in the front portion 630a, avoiding the center portion. The front portion 630a can also be said to be an intake portion. The cylindrical portion 630b is provided on the periphery of the front portion 630a so as to surround the periphery and protrude from the periphery to the rear side. A male screw portion 630bb that screws into the female screw portion 110a of the fixing member 11 is formed on the outer circumferential surface of the cylindrical portion 630b. The flange portion 630c is provided on the periphery of the front portion 630a so as to surround the front portion 630a. The flange portion 630c protrudes from the periphery of the front portion 630a in the radial direction of the front portion 630a. The front surface 630a viewed from the front side resembles the front portion 330 of the fan 10C described above viewed from the front side (see FIG. 13).

[0173] The rear portion 631 includes a rear portion 631a and a cylindrical portion 631b. The cylindrical portion 631b is provided on the peripheral edge of the rear portion 631a so as to surround the peripheral edge and protrude from the peripheral edge to the front side. A plurality of exhaust ports 631c are provided in the rear portion 631a and the cylindrical portion 631b. A first recess 631aa is provided in the center of the outer surface of the rear portion 631a. A motor 15 is fixed to the first recess 631aa. A protrusion 631ab corresponding to the first recess 631aa is provided on the inner surface of the rear portion 631a. A cylindrical connecting portion 141 of the blade portion 14 covers the protrusion 631ab. A rotating shaft 150 of the motor 15 in the first recess 631aa extends to the outside of the protrusion 631ab and is connected to the connecting portion 141 of the blade portion 14.

[0174] A connector 64 is fixed to the outer surface of the rear portion 631a. A majority of the connector 64 is located below the motor 15. A second recess 631ac is provided in a portion of the outer surface of the rear portion 631a below the connector 64. The second recess 631ac extends downward and reaches the periphery of the rear portion 631a.

[0175] The cable 68 has a connector 68a at one end thereof. The connector 68a is detachable from the connector 64 of the main body 62. The connection port of the connector 68a in the connector 64 faces downward. Therefore, the connector 68a of the cable 68 is connected to the connector 64 of the main body 62 from below. Since the second recess 631ac exists on the lower side of the connector 64, it becomes easy to connect the connector 68a to the connector 64 from below.

[0176] Cylindrical portion 630b of front portion 630 and cylindrical portion 631b of rear portion 631 are connected to each other and form a cylindrical peripheral wall portion (in other words, a side surface portion) 635 of the entire housing 63. When blade portion 14 rotates, air is taken into housing 63 from intake port 630aa, and the air taken into housing 63 is exhausted to the outside of housing 63 from exhaust port 631c.

[0177] The cover portion 632 is attached to the rear surface portion 631a of the rear portion 631 so as to cover the first recess 631aa and the connector 64. As a result, the cover portion 632 covers the motor 15 in the first recess 631aa.

[0178] The battery device 65 includes a housing 650, and the circuit board 16 and the battery 17 housed in the housing 650. The housing 650 is substantially rectangular. The housing 650 includes a pair of main surfaces 650a and 650b facing each other, and a side surface 650c connected to the periphery of the main surfaces 650a and 650b so as to surround the main surfaces 650a and 650b. As shown in FIG. 31, the light emitting units 162aaa, 162ab, 162ac, 162ad, 162ae, and 162af included in the display unit 162 of the circuit board 16 in the housing 650 are exposed from the main surface 650a. In addition, the operation button 163a included in the operation unit 163 of the circuit board 16 in the housing 650 is exposed from the main surface 650a. The battery device 65 includes the display unit 162 and the operation unit 163.

[0179] An end of the cable 68 opposite to the connector 68a side is fixed inside the housing 650. An end of the cable 68 opposite to the connector 68a side is connected to a control unit 161 of the circuit board 16 inside the housing 650. The cable 68 is taken out from an upper surface 650ca of the housing 650 to the outside of the housing 650 and connected to a connector 64 of the main body 62. A control signal for controlling the motor 15, which is output from the control unit 161, is supplied to the motor 15 through the cable 68, the connector 64 of the main body 62, and the lead wire 19.

[0180] The mounting portion 66 is ring-shaped and has an opening 66a. The mounting portion 66 is connected to an upper surface 650ca of the side surface 650c of the housing 650. Specifically, the mounting portion 66 is connected to an end of the upper surface 650ca on the main surface 650b side. The mounting portion 66 is attached to the housing 650 so that the circular shape of the mounting portion 66 is parallel to the main surfaces 650a and 650b.

[0181] When the fan 10F having the above configuration is attached to the mounting hole 4 of the garment 2, first, the housing 63 of the main body 62 is inserted into the mounting hole 4 from the outside 500 of the garment 2. At this time, the housing 63 is inserted into the mounting hole 4 from the rear portion 631 side. When the housing 63 is inserted into the mounting hole 4 from the rear portion 631 side, the flange portion 630c of the front portion 630 abuts against the surface of the outside 500 of the periphery 5 of the mounting hole 4 of the garment 2 without passing through the mounting hole 4.

[0182] Next, the fixing member 11 is attached to the housing 63 from the inside 510 of the garment 2 so that the flange portion 111 of the fixing member 11 abuts against the surface of the inside 510 of the periphery 5 of the garment 2. Specifically, the fixing member 11 is attached to the front portion 630 so that the female screw portion 110a on the inner periphery of the attachment portion 110 of the fixing member 11 is screwed into the male screw portion 630bb on the outer periphery of the tubular portion 630b protruding to the inside 510 of the garment 2 while the flange portion 111 abuts against the surface of the inside 510 of the periphery 5. Then, the fixing member 11 is tightened clockwise as viewed from the inside 510 of the garment 2, so that the flange portion 630c of the front portion 630 and the flange portion 111 of the fixing member 11 sandwich the periphery 5 of the garment 2. As a result, the main body portion 62 is fixed to the garment 2.

[0183] Next, with the housing 650 of the battery device 65 facing downward and the main surface 650a of the housing 650 facing backward, the opening 66a of the attachment portion 66 is brought close to the main body portion 62 from the inside 510 of the garment 2. Then, the opening 66a is brought close to the main body portion 62, and the attachment portion 110 of the fixing member 11 of the main body portion 62 is passed through the opening 66a. At this time, the flange portion 111 of the fixing member 11 abuts on the peripheral end of the attachment portion 66 without passing through the opening 66a. When the attachment portion 110 of the fixing member 11 is passed through the opening 66a, the battery device 65 is suspended from the main body portion 62. The attachment portion 66 can also be said to be a suspension portion for suspending the battery device 65 from the main body portion 62.

[0184] Next, the retaining ring 67 is brought close to the main body 62 from the inside 510 of the garment 2, and the mounting portion 110 of the fixing member 11 is passed through the retaining ring 67. In this example, a groove into which the retaining ring 67 fits is formed on the outer peripheral surface of the mounting portion 110 of the fixing member 11. When the mounting portion 110 of the fixing member 11 is passed through the retaining ring 67, the retaining ring 67 is fitted into the groove on the outer peripheral surface of the mounting portion 110. As a result, the mounting portion 66 is sandwiched between the front flange portion 111 and the rear retaining ring 67, and the mounting portion 661 is fixed to the main body 62. That is, the battery device 65 is fixed to the main body 62. Finally, when the connector 68a of the cable 68 is connected to the connector 64 of the main body 62, the attachment of the fan 10F to the garment 2 is completed. When the blades 14 of the fan 10F attached to the garment 2 rotate, air from the outside 500 of the garment 2 is taken into the inside 510 of the garment 2 through the air intake 630aa and the air exhaust 631c.

[0185] On the other hand, when the fan 10F is removed from the garment 2, first, the connector 68a of the cable 68 is removed from the connector 64 of the main body 62. Next, the retaining ring 67 is removed from the fixing member 11. Next, the attachment portion 66 is removed from the fixing member 11. Next, the fixing member 11 is rotated counterclockwise when viewed from the inside 510 of the garment 2, and the fixing member 11 is removed from the housing 63. Then, the housing 63 is taken out of the attachment hole 4.

[0186] In this way, in this example, since the battery device 65 is fixed to the main body 62 so as to be located around the main body 62, the cable 68 connecting the battery device 65 and the main body 62 can be shortened. This reduces the possibility of the cable 68 being damaged. As a result, it reduces the possibility of malfunction of the fan 10F.

[0187] In addition, since the cable 68 can be shortened, the fan 10F can be attached to the garment 2 more easily.

[0188] Furthermore, in this example, since an operation unit 163 is provided for each fan 10, the user can control each fan 10 individually.

[0189] Furthermore, in this example, since the battery 17 is located on the inside 510 of the garment 2, the possibility of the battery 17 being damaged can be reduced.

[0190] <Seventh Structure Example> FIG. 32 is a diagram showing an example of the internal structure of the fan 10 (sometimes referred to as fan 10G) according to this embodiment. FIG. 32 shows the fan 10G attached to the garment 2. As shown in FIG. 32, the fan 10G includes the main body 62, the fixing member 11, the battery device 65, the mounting portion 66, and the cable 68. However, the opening 66a of the mounting portion 66 of the fan 10G is slightly smaller than the opening 66a of the mounting portion 66 of the fan 10F. The mounting portion 66 of the fan 10G extends slightly upward from the upper surface 650ca of the housing 650 in a straight line, then inclines toward the main surface 650b, and then extends upward in a straight line. The fan 10G does not include the above-mentioned retaining ring 67.

[0191] When the fan 10G is attached to the mounting hole 4 of the garment 2, first, the housing 63 of the main body 62 is inserted into the mounting hole 4 from the outside 500 of the garment 2. At this time, the housing 63 is inserted into the mounting hole 4 from the rear portion 631 side. When the housing 63 is inserted into the mounting hole 4 from the rear portion 631 side, the flange portion 630c of the front portion 630 abuts against the surface of the outside 500 of the periphery 5 of the mounting hole 4 of the garment 2 without passing through the mounting hole 4.

[0192] Next, with the main surface 650a of the housing 650 of the battery device 65 facing rearward, the opening 66a of the attachment portion 66 is brought close to the housing 63 from the inside 510 of the garment 2. Then, the front portion 630 of the housing 63 is passed through the opening 66a, and the peripheral portion of the attachment portion 66 comes into contact with the inner surface of the peripheral portion 5 of the garment 2.

[0193] Next, the fixing member 11 is attached to the housing 63 from the inside 510 of the garment 2 so that the flange portion 111 of the fixing member 11 abuts against the peripheral portion of the attachment portion 66. Specifically, the fixing member 11 is attached to the front portion 630 so that the female screw portion 110a on the inner peripheral surface of the attachment portion 110 of the fixing member 11 is screwed into the male screw portion 630bb on the outer peripheral surface of the cylindrical portion 630b protruding to the inside 510 of the garment 2 while the flange portion 111 abuts against the peripheral portion of the attachment portion 66. Then, the fixing member 11 is tightened clockwise as viewed from the inside 510 of the garment 2, so that the flange portion 630c of the front portion 630 and the flange portion 111 of the fixing member 11 sandwich the peripheral portion of the attachment portion 66 and the peripheral portion 5 of the garment 2. As a result, the battery device 65 is fixed to the main body portion 62. Finally, when the connector 68a of the cable 68 is connected to the connector 64 of the main body 62, the attachment of the fan 10G to the garment 2 is completed.

[0194] On the other hand, when the fan 10G is removed from the garment 2, first, the connector 68a of the cable 68 is removed from the connector 64 of the main body 62. Next, the fixing member 11 is rotated counterclockwise when viewed from the inside 510 of the garment 2, and the fixing member 11 is removed from the housing 63. Next, the attachment portion 66 is removed from the fixing member 11. Finally, the housing 63 is taken out of the attachment hole 4.

[0195] In this way, in this example, since the battery device 65 is fixed to the main body 62 so as to be located around the main body 62, the cable 68 connecting the battery device 65 and the main body 62 can be shortened. This reduces the possibility of the cable 68 being damaged. As a result, it reduces the possibility of the fan 10G malfunctioning.

[0196] In addition, since the cable 68 can be shortened, the fan 10G can be easily attached to the garment 2.

[0197] Furthermore, in this example, since an operation unit 163 is provided for each fan 10, the user can control each fan 10 individually.

[0198] Furthermore, in this example, since the battery 17 is located on the inside 510 of the garment 2, the possibility of the battery 17 being damaged can be reduced.

[0199] Furthermore, in this example, since the retaining ring 67 is not necessary, the configuration of the fan 10G is simplified.

[0200] Furthermore, in this example, the battery device 65 is fixed to the housing 63 by the fixing member 11 and the housing 63 clamping the peripheral portion of the mounting portion 66, so that the battery device 65 can be fixed to the housing 63 more easily than in the case where a retaining ring 67 is used.

[0201] <8th Structure Example> Fig. 33 is a diagram showing an example of the internal structure of the fan 10 according to this example (sometimes referred to as fan 10H). Fig. 33 shows the fan 10H attached to clothing 2. Fig. 34 is a diagram showing the fan 10H as seen from behind.

[0202] As shown in FIGS. 33 and 34, the fan 10H includes the main body 62 and the cable 68. However, the second recess 631ac is not provided on the outer surface of the back surface 631a of the rear portion 631 of the housing 63 of the main body 62. The main body 62 does not include the connector 64. The cable 68 does not include the connector 68a. The end of the cable 68 on the main body 62 side is fixed to the main body 62. Specifically, the end of the cable 68 on the main body 62 side is fixed to the outer surface of the back surface 631a of the rear portion 631 of the housing 63. The lead wire 19 extending from the motor 15 is connected to the end.

[0203] The fan 10H includes the above-mentioned fixing member 11 and the battery device 65, as well as the main body 62 and the cable 68, and an attachment portion 76 for attaching the battery device 65 to the main body 62. The attachment portion 76 includes a pair of rod-shaped connecting portions 760 for connecting the housing 650 and the main body 62. One end 760a and the other end 760b of each connecting portion 760 are connected to the main body 62 and the housing 650 of the battery device 65, respectively. The end 760a of the connecting portion 760 is rotatably connected to the cylindrical portion 631b of the rear portion 631 of the housing 63 of the main body 62. The end 760b of the connecting portion 760 is fixed to the upper surface 650ca of the housing 650. The attachment portion 76 can rotate around the end 760a of each connecting portion 760 as a starting point, in a direction perpendicular to the length direction of the connecting portion 760 and the front-rear direction of the fan 10H (left-right direction on the paper surface of FIG. 34). The mounting portion 76 and the battery device 65 to which it is connected rotate together. By rotating, the battery device 65 can be in a first state in which it is located below the main body portion 62, and in a second state in which it is located behind the main body portion 62, as shown in FIG.

[0204] When the fan 10H is attached to the garment 2 and no force other than gravity is applied to the attachment part 76 and the battery device 65 from the outside, the battery device 65 is suspended from the main body part 62 by the attachment part 76 and is in the first state. When the user lifts the battery device 65 diagonally upward and to the rear while the battery device 65 is in the first state, the battery device 65 enters the second state.

[0205] When the fan 10H having the above-described configuration is attached to the attachment hole 4 of the clothing 2, first, the battery device 65 suspended from the main body 62 is lifted up, and the battery device 65 is changed from the first state to the second state.

[0206] Next, the battery device 65 in the second state, the attachment portion 75 connected thereto, and the housing 63 of the main body portion 62 are inserted into the attachment hole 4 from the outside 500 of the garment 2. At this time, the housing 63 is inserted into the attachment hole 4 from the rear portion 631 side. When the housing 63 is inserted into the attachment hole 4 from the rear portion 631 side, the flange portion 630c of the front portion 630 abuts against the surface of the outside 500 of the periphery 5 of the attachment hole 4 of the garment 2 without passing through the attachment hole 4.

[0207] Next, with the battery device 65 in the second state, the opening of the attachment portion 110 of the fixing member 11 is brought closer to the battery device 65 at the rear of the main body portion 62 from the inside 510 of the garment 2. Then, the battery device 65, the attachment portion 75, and the housing 63 of the main body portion 62 are sequentially passed through the opening of the attachment portion 110 of the fixing member 11. Then, the fixing member 11 is attached to the front portion 630 such that the female screw portion 110a on the inner peripheral surface of the attachment portion 110 of the fixing member 11 is screwed into the male screw portion 630bb on the outer peripheral surface of the tubular portion 630b protruding to the inside 510 of the garment 2 while the flange portion 111 of the fixing member 11 abuts against the surface of the inside 510 of the periphery portion 5 of the garment 2. Then, the fixing member 11 is tightened clockwise when viewed from the inside 510 of the garment 2, whereby the flange portion 630c of the front portion 630 and the flange portion 111 of the fixing member 11 clamp the peripheral portion 5 of the garment 2. Thereafter, the battery device 65 is set to the first state, and attachment of the fan 10H to the garment 2 is completed.

[0208] In this way, in this example, since the battery device 65 is attached to the main body 62 so as to be located around the main body 62, the cable 68 connecting the battery device 65 and the main body 62 can be shortened. This reduces the possibility of the cable 68 being damaged. As a result, it reduces the possibility of malfunction of the fan 10H.

[0209] In addition, since the cable 68 can be shortened, the fan 10H can be attached to the garment 2 more easily.

[0210] Furthermore, in this example, since an operation unit 163 is provided for each fan 10, the user can control each fan 10 individually.

[0211] Furthermore, in this example, since the battery 17 is located on the inside 510 of the garment 2, the possibility of the battery 17 being damaged can be reduced.

[0212] Furthermore, in this example, when attaching the fan 10H to the garment 2, there is no need to connect the cable 68 to the main body 62, making it easier to attach the fan 10H to the garment 2. Furthermore, when removing the fan 10H from the garment 2, there is no need to remove the cable 68 from the main body 62, making it easier to remove the fan 10H from the garment 2.

[0213] <Ninth structural example> FIG. 35 is a diagram showing an example of the internal structure of the fan 10 according to this example (sometimes referred to as fan 10I). FIG. 35 shows the fan 10I attached to clothing 2. As shown in FIG. 35, the fan 10I includes a main body 72, a battery device 65, and a holder 74 that holds the battery device 65. The main body 72 includes a housing 73, and the above-mentioned blades 14 and motor 15. The blades 14 and motor 15 are housed in the housing 73.

[0214] The housing 73 is made of, for example, resin. The housing 73 includes a front portion 330 (in other words, the fixing portion 330) of the above-mentioned fan 10C, a rear portion 731, and a cover portion 732. The blade portion 14 and the motor 15 are fixed to the rear portion 731. It can be said that the rear portion 731 is a holding portion that holds the blade portion 14 and the motor 15. The front portion 330 is detachable from the rear portion 731. The front portion 330 functions as a fixing portion for fixing the rear portion 731 that holds the blade portion 14 and the like to the clothing 2. Hereinafter, the rear portion 731 may be referred to as the holding portion 731.

[0215] The outer shape of the holding portion 731 is substantially circular when viewed from the rear side. The holding portion 731 includes a rear portion 731a, a cylindrical portion 731b, and a flange portion 731c. The cylindrical portion 731b is provided on the peripheral edge of the rear portion 731a so as to surround the peripheral edge and protrude from the peripheral edge to the front side. The rear portion 731a and the cylindrical portion 731b are provided with a plurality of exhaust ports 731d. A female screw portion 731bb that screws with the male screw portion 330bb of the fixing portion 330 is formed on the inner peripheral surface of the cylindrical portion 731b. The cylindrical portion 330b of the fixing portion 330 and the cylindrical portion 731b of the holding portion 731 are connected to each other by screwing the male screw portion 330bb and the female screw portion 731bb, and constitute a cylindrical peripheral wall portion (in other words, a side surface portion) 735 of the entire housing 73. When the blade portion 14 rotates, air is taken into the housing 73 through the intake port 330aa, and the air taken into the housing 73 is exhausted to the outside of the housing 73 through the exhaust port 731d.

[0216] The flange portion 731c is provided on the outer peripheral surface of the cylindrical portion 731b so as to surround the cylindrical portion 731b. The flange portion 731c protrudes from the outer peripheral surface of the cylindrical portion 731b in the radial direction of the cylindrical portion 731b. The flange portion 731c is located slightly rearward of the front end of the cylindrical portion 731b. Therefore, the flange portion 731c is not provided on the front end 731ba of the cylindrical portion 731b.

[0217] A recess 731aa is provided in the center of the outer surface of the rear portion 731a of the holding portion 731. A motor 15 is fixed to the recess 731aa. A protrusion 731ab corresponding to the recess 731aa is provided on the inner surface of the rear portion 731a. A cylindrical connecting portion 141 of the blade portion 14 covers the protrusion 731ab. A rotating shaft 150 of the motor 15 in the recess 731aa extends to the outside of the protrusion 731ab and is connected to the connecting portion 141 of the blade portion 14.

[0218] The cover portion 732 is attached to the rear portion 731a so as to cover the recess 731aa of the rear portion 731a of the holding portion 731. As a result, the cover portion 732 covers the motor 15 in the recess 731aa.

[0219] The holding portion 74 for holding the battery device 65 is integrally formed with the housing 73. The holding portion 74 functions as a fixing portion for fixing the battery device 65 to the housing 73. The holding portion 74 includes a first portion 741 for covering the upper surface 650ca of the housing 650 of the battery device 65, a second portion 742 for covering the rear main surface 650a of the housing 650, and a third portion 743 for covering the front main surface 650b of the housing 650. The first portion 741 is connected to a lower portion of the cylindrical portion 731b of the holding portion 731. The second portion 742 extends downward from the first portion 741 to reach the curved lower surface 650cb of the side surface 650c of the housing 650, and covers a part of the lower surface 650cb. Similarly, the third portion 743 extends downward from the first portion 741 to reach the lower surface 650cb, and covers a part of the lower surface 650cb. An opening is provided in the second portion 742. The light emitting portions 162aa, 162ab, 162ac, 162ad, 162ae, and 162af and the operation button 163a exposed from the main surface 650a of the housing 650 can be viewed from the inside 510 of the garment 2 through the opening of the second portion 742.

[0220] The lead wire 19 extending downward from the motor 15 passes through the housing 73 and reaches the upper surface 650ca of the housing 650 held by the holding portion 74, and then enters the housing 650 from the upper surface 650ca and is connected to the circuit board 16 inside the housing 650.

[0221] When the fan 10I having the above configuration is attached to the mounting hole 4 of the garment 2, first, the front end 731ba of the tubular portion 731b of the holding portion 731 of the housing 73 is inserted into the mounting hole 4 from the inside 510 of the garment 2. At this time, the flange portion 731c of the holding portion 731 abuts against the surface of the inside 510 of the periphery 5 of the mounting hole 4 of the garment 2 without passing through the mounting hole 4. In addition, the holding portion 74 is located on the inside 510 of the garment 2 without passing through the mounting hole 4.

[0222] Next, the fixing part 330 is attached to the holding part 731 from the outside 500 of the garment 2 so that the flange part 330c of the fixing part 330 abuts against the surface of the outside 500 of the peripheral part 5 of the garment 2. Specifically, the fixing part 330 is attached to the holding part 731 so that the male screw part 330bb of the cylindrical part 330b of the fixing part 330 is screwed into the female screw part 731bb of the cylindrical part 731b of the holding part 731 while the flange part 330c abuts against the surface of the outside 500 of the peripheral part 5. Then, the fixing part 330 is tightened clockwise as viewed from the outside 500 of the garment 2, so that the flange part 330c of the fixing part 330 and the flange part 731c of the holding part 731 hold the peripheral part 5 of the garment 2 between them. In this way, the fan 10I is fixed to the garment 2. When the blades 14 of the fan 10I fixed to the garment 2 rotate, air from the outside 500 of the garment 2 is taken into the inside 510 of the garment 2 through the air intake 330aa and the air exhaust 731d.

[0223] On the other hand, when the fan 10I is removed from the garment 2, the fixing part 330 is rotated counterclockwise when viewed from the outside 500 of the garment 2, and the fixing part 330 is removed from the holding part 731. Then, the front end 731ba of the cylindrical part 731b of the holding part 731 is taken out from the attachment hole 4.

[0224] In this way, in this example, the battery device 65 is fixed to the main body 72 so as to be located around the housing 73, so that the wiring (the lead wire 19 in this example) connecting the battery device 65 and the main body 72 can be shortened. This reduces the possibility of the wiring being damaged. As a result, it reduces the possibility of malfunction of the fan 10I.

[0225] Furthermore, in this example, since a cable for connecting the battery device 65 and the main body 72 is not required, the fan 10I can be easily attached to the clothing 2.

[0226] Furthermore, in this example, since an operation unit 163 is provided for each fan 10, the user can control each fan 10 individually.

[0227] Furthermore, in this example, since the battery 17 is located on the inside 510 of the garment 2, the possibility of the battery 17 being damaged can be reduced.

[0228] The above description refers to various structural examples of the fan 10. The following describes various operational examples of the fan 10. The operational examples of the fan 10 described below can be applied to each of the above-mentioned fans 10A to 10I.

[0229] <First operation example> The fan 10 according to this example is capable of wireless communication with another device. FIG. 36 is a diagram showing an example of the configuration of the circuit board 16 (sometimes referred to as the circuit board 16A) according to this example. As shown in FIG. 36, the circuit board 16A includes a wireless communication unit 165 provided on the board 160. The wireless communication unit 165 can also be called a wireless communication circuit. The wireless communication unit 165 includes an antenna 165a. The wireless communication unit 165 can wirelessly communicate with a device outside the fan 10 using the antenna 165a. The wireless communication unit 165 is controlled by the control unit 161. In this example, the wireless communication unit 165 operates whether the fan 10 is in a power-off state or a power-on state. The antenna 165a may be provided on another part instead of the board 160. The antenna 165a may be provided on, for example, a housing provided on the fan 10. Hereinafter, a device with which the wireless communication unit 165 can communicate may be called an external device.

[0230] The wireless communication unit 165 can wirelessly communicate with an external device in accordance with at least one type of wireless communication standard. The wireless communication standard to which the wireless communication unit 165 conforms includes, for example, a short-range wireless communication standard. For example, the wireless communication standard to which the wireless communication unit 165 conforms may include Bluetooth (registered trademark), ZigBee (registered trademark), or NFC (Near Field Communication). The wireless communication standard to which the wireless communication unit 165 conforms may include a standard corresponding to a wireless LAN (Local Area Network), such as WiFi. The wireless communication standard to which the wireless communication unit 165 conforms may include a standard corresponding to a low power wide area network (LPWA). For example, the wireless communication standard to which the wireless communication unit 165 conforms may include SIGFOX, LoRaWAN, or NB-IoT. In the following, the operation of the fan 10 will be described taking as an example a case in which the wireless communication unit 165 communicates with an external device in accordance with Bluetooth.

[0231] External devices with which the fan 10 can wirelessly communicate include various devices. External devices with which the fan 10 can wirelessly communicate include, for example, other fans 10, portable electronic devices, and electric machines. Portable electronic devices with which the fan 10A can wirelessly communicate include mobile phones such as smartphones, tablet terminals, notebook personal computers, wearable devices, and the like. Wearable devices with which the fan 10A can wirelessly communicate may be of a wristband or watch type that is worn on the arm, a headband or glasses type that is worn on the head, or a clothing type that is worn on the body.

[0232] As an example, the operation of each of the fans 10 when the multiple fans 10 communicate wirelessly with each other in accordance with Bluetooth will be described. For example, the multiple fans 10 attached to the same garment 2 are paired with each other. This allows the multiple fans 10 attached to the same garment 2 to communicate wirelessly with each other when each of them is in a power-on state. Hereinafter, unless otherwise specified, the multiple fans 10 refers to the multiple paired fans 10. Furthermore, one fan 10 of interest among the multiple fans 10 may be referred to as a target fan 10.

[0233] When the operation button 163a of the target fan 10 in the power-on state is pressed briefly, the control unit 161 of the target fan 10 changes the air volume of the fan 10A by controlling the rotation speed of the motor 15, and generates air volume information indicating the changed air volume. The wireless communication unit 165 transmits the air volume information generated by the control unit 161 to the fans 10 other than the target fan 10 among the multiple fans 10. When the wireless communication unit 165 receives the air volume information of the fan 10 in the power-on state, the control unit 161 controls the motor 15 to set the air volume of the fan 10 to the air volume indicated by the received air volume information. Thus, by pressing the operation button 163a of one of the multiple fans 10 briefly, the air volumes of the multiple fans 10 are set to the same.

[0234] Furthermore, when the operation button 163a of the target fan 10 in the power-on state is pressed and held, the control unit 161 of the target fan 10 may generate a power-off signal to instruct the other fans 10 to be powered off before the target fan 10 is powered off. In this case, before the target fan 10 is powered off, the wireless communication unit 165 of the target fan 10 transmits a power-off signal to the fans 10 other than the target fan 10 among the multiple fans 10. When the wireless communication unit 165 of the power-on fan 10 receives the power-off signal, the control unit 161 places the fan 10 in the power-on state. Thus, when the operation button 163a of one fan 10 among the multiple fans 10 is pressed and held, all of the multiple fans 10 are powered off.

[0235] Furthermore, when the operation button 163a of a target fan 10 in a power-off state is pressed and held, the control unit 161 of the target fan 10 may power on the target fan 10 and generate a power-on signal that instructs the other fans 10 to power on. In this case, the wireless communication unit 165 of the target fan 10 transmits a power-on signal to the fans 10 other than the target fan 10 among the multiple fans 10. When the wireless communication unit 165 of the fan 10 in a power-off state receives the power-on signal, the control unit 161 powers the fan 10 on. Thus, when the operation button 163a of one fan 10 among the multiple fans 10 is pressed and held, all of the multiple fans 10 are powered on.

[0236] As another example, the operation of the fan 10 and the portable electronic device when the fan 10 wirelessly communicates with the portable electronic device such as a mobile phone will be described. Fig. 37 is a diagram showing an example of the configuration of a portable electronic device 800. As shown in Fig. 37, the portable electronic device 800 includes a control unit 801, a wireless communication unit 802, a display unit 803, a touch panel 804, and a sensor 805.

[0237] The control unit 801 can generally manage the operation of the portable electronic device 800 by controlling the other components of the portable electronic device 800. The control unit 801 can also be called a control circuit. The control unit 801 includes at least one processor to provide control and processing power for executing various functions, as described in more detail below. The above description of the at least one processor included in the control unit 161 of the fan 10 can also be applied to the at least one processor included in the control unit 801. Note that all or some of the functions of the control unit 801 may be realized by a hardware circuit that does not require software to realize the function.

[0238] The wireless communication unit 802 can wirelessly communicate with a device outside the portable electronic device 800. The wireless communication unit 802 can also be called a wireless communication circuit. The wireless communication unit 802 can wirelessly communicate with an external device in compliance with at least one type of wireless communication standard. The wireless communication standard to which the wireless communication unit 802 conforms includes, for example, a short-range wireless communication standard. For example, the wireless communication standard to which the wireless communication unit 802 conforms may include Bluetooth, ZigBee, or NFC. The wireless communication standard to which the wireless communication unit 802 conforms may include a standard corresponding to wireless LAN. The wireless communication standard to which the wireless communication unit 802 conforms may include a standard corresponding to LPWA. For example, the wireless communication standard to which the wireless communication unit 802 conforms may include SIGFOX, LoRaWAN, or NB-IoT.

[0239] The display unit 803 is, for example, a liquid crystal display or an organic EL display. The display unit 803 is controlled by the control unit 801 to display various types of information such as characters, symbols, and figures on a display surface 803a.

[0240] The touch panel 804 is capable of detecting an operation performed by an operator such as a finger on the display surface 803a. The touch panel 804 is, for example, a projected capacitive touch panel. When a user performs an operation on the display surface 803a with an operator such as a finger, the touch panel 804 is capable of inputting an electric signal corresponding to the operation to the control unit 801. The control unit 801 is capable of identifying the content of the operation performed on the display surface 803a based on the electric signal from the touch panel 804. Then, the control unit 801 is capable of performing processing corresponding to the identified content of the operation.

[0241] The sensor 805 includes, for example, an acceleration sensor. The sensor 805 may include a sensor other than an acceleration sensor. For example, the sensor 805 may include at least one of a proximity sensor, a gyro sensor, a fingerprint sensor, a temperature sensor, an air pressure sensor, a position detection sensor, and a geomagnetic sensor.

[0242] The configuration of the portable electronic device 800 is not limited to the above example. The portable electronic device 800 may include, for example, a speaker and a microphone. The portable electronic device 800 may also include a light-emitting unit such as an LED.

[0243] When the fan 10 and the portable electronic device 800 are paired, the fan 10 and the portable electronic device 800 can wirelessly communicate with each other in accordance with Bluetooth. The portable electronic device 800 may control the operation of the fan 10 by wirelessly communicating with the fan 10.

[0244] For example, when the touch panel 804 detects a predetermined operation on the display surface 803a, the control unit 801 of the portable electronic device 800 causes the display unit 803 to display a screen 810 for turning on the power of the fan 10. Fig. 38 is a diagram showing an example of the screen 810 displayed on the display surface 803a.

[0245] 38, a first operation button 811 and a second operation button 812 are displayed on a screen 810. When the touch panel 804 detects an operation on the first operation button 811, the control unit 801 generates a power-on signal that instructs the fan 10 to be turned on. On the other hand, when the touch panel 804 detects an operation on the second operation button 812, the control unit 801 does not generate a power-on signal. When the control unit 801 generates the power-on signal, the wireless communication unit 802 transmits the generated power-on signal to the fan 10. In the fan 10 that is in a power-off state, when the wireless communication unit 165 receives the power-on signal, the control unit 161 turns the fan 10 on.

[0246] In this way, the user of the portable electronic device 800 can turn on the power of the fan 10 by performing a predetermined operation on the display surface 803a.

[0247] Furthermore, when the touch panel 804 detects a predetermined operation on the display surface 803a, the control unit 801 of the portable electronic device 800 may cause the display unit 803 to display a screen 820 for turning off the power of the fan 10. Fig. 39 is a diagram showing an example of the screen 820 displayed on the display surface 803a.

[0248] 39, a first operation button 821 and a second operation button 822 are displayed on a screen 820. When the touch panel 804 detects an operation on the first operation button 821, the control unit 801 generates a power-off signal that instructs the fan 10 to be turned off. On the other hand, when the touch panel 804 detects an operation on the second operation button 822, the control unit 801 does not generate a power-off signal. When the control unit 801 generates the power-off signal, the wireless communication unit 802 transmits the generated power-off signal to the fan 10. In the fan 10 that is in a power-on state, when the wireless communication unit 165 receives the power-off signal, the control unit 161 turns the fan 10 into a power-off state.

[0249] In this way, the user of the portable electronic device 800 can turn off the power of the fan 10 by performing a predetermined operation on the display surface 803a.

[0250] Furthermore, portable electronic device 800 may set the air volume of fan 10 by wirelessly communicating with fan 10. For example, when touch panel 804 detects a predetermined operation on display surface 803a, control unit 801 causes display unit 803 to display screen 830 for setting the air volume of fan 10. Fig. 40 is a diagram showing an example of screen 830 displayed on display surface 803a.

[0251] As shown in FIG. 40, a first operation button 831, a second operation button 832, and a third operation button 833 are displayed on a screen 830. When the touch panel 804 detects an operation on the first operation button 831, the control unit 801 generates a first air volume signal that instructs the fan 10 to set the air volume to "large". The first air volume signal generated by the control unit 801 is transmitted from the wireless communication unit 802 to the fan 10. When the touch panel 804 detects an operation on the second operation button 832, the control unit 801 generates a second air volume signal that instructs the fan 10 to set the air volume to "medium". The second air volume signal generated by the control unit 801 is transmitted from the wireless communication unit 802 to the fan 10. When the touch panel 804 detects an operation on the third operation button 833, the control unit 801 generates a third air volume signal that instructs the fan 10 to set the air volume to "small". The third air volume signal generated by the control unit 801 is transmitted from the wireless communication unit 802 to the fan 10 .

[0252] When the wireless communication unit 165 receives a first air volume signal in the power-on state of the fan 10, the control unit 161 controls the motor 15 to set the air volume of the fan 10 to "large." When the wireless communication unit 165 receives a second air volume signal, the control unit 161 controls the motor 15 to set the air volume of the fan 10 to "medium." And when the wireless communication unit 165 receives a third air volume signal, the control unit 161 controls the motor 15 to set the air volume of the fan 10 to "small."

[0253] In this way, the user of the portable electronic device 800 can set the air volume of the fan 10 by performing a predetermined operation on the display surface 803a.

[0254] Furthermore, the fan 10 may transmit information about itself as fan information to the portable electronic device 800. In this case, when the fan 10 is in a power-on state, the control unit 161 generates the fan information. Then, the wireless communication unit 165 transmits the fan information to the portable electronic device 800. In the portable electronic device 800, when the wireless communication unit 802 receives the fan information, the control unit 801 causes the received fan information to be displayed on, for example, the display unit 803.

[0255] The fan information may include, for example, the remaining charge of the battery 17 of the fan 10. The fan information may also include the continuous operation time of the fan 10. The continuous operation time means the time during which the blades 14 of the fan 10 are continuously rotating. In other words, the continuous operation time means the time during which the motor 15 of the fan 10 is continuously rotating. The fan information may also include the remaining operable time. The remaining operable time means the time during which the blades 14 of the fan 10 can continue to rotate continuously from the present. In other words, the remaining operable time means the time during which the motor 15 of the fan 10 can continue to rotate continuously from the present. The control unit 161 of the fan 10 can obtain the remaining operable time based on the remaining charge of the battery 17.

[0256] 41 is a diagram showing an example of a screen 840 displayed on the display surface 803a when the display unit 803 of the portable electronic device 800 displays fan information. The fan information is displayed on the screen 840. Specifically, the screen 840 displays first information 841 indicating the remaining charge of the battery 17, second information 842 indicating the continuous operating time, and third information 843 indicating the remaining operable time.

[0257] The fan information may include other information, such as the current air volume of the fan 10.

[0258] As another example, the operation of the fan 10 and the electric machine when the fan 10 wirelessly communicates with the electric machine will be described. Fig. 42 is a diagram showing an example of the electrical configuration of an electric machine 850. The electric machine 850 is, for example, an electric machine that generates a lot of dust when it is being used. For example, the electric machine 850 is an electric tool that generates a lot of dust when it is being used, such as a chain saw, a hedge trimmer, or a brush cutter. Examples of electric tools that generate a lot of dust when they are being used include disc grinders, circular saws, and steel cutters.

[0259] 42, an electric machine 850 includes a control unit 851, a wireless communication unit 852, and a motor 853. The motor 853 operates a moving part of the electric machine 850. The moving part of the electric machine 850 is, for example, a grindstone, a tip saw, or a blade.

[0260] The control unit 851 can generally manage the operation of the electric machine 850 by controlling other components of the electric machine 850. The control unit 851 can also be called a control circuit. The control unit 851 includes at least one processor to provide control and processing power for executing various functions, as described in more detail below. The above description of the at least one processor included in the control unit 161 of the fan 10 can also be applied to the at least one processor included in the control unit 851 of the electric machine 850. Note that all or some of the functions of the control unit 851 may be realized by a hardware circuit that does not require software to realize the function.

[0261] The wireless communication unit 852 can wirelessly communicate with a device outside the electric machine 8500. The wireless communication unit 852 can also be called a wireless communication circuit. The wireless communication unit 852 can wirelessly communicate with an external device in compliance with at least one type of wireless communication standard. The wireless communication standard to which the wireless communication unit 852 conforms includes, for example, a short-range wireless communication standard. For example, the wireless communication standard to which the wireless communication unit 802 conforms may include Bluetooth, ZigBee, or NFC. The wireless communication standard to which the wireless communication unit 852 conforms may include a standard corresponding to wireless LAN. The wireless communication standard to which the wireless communication unit 852 conforms may include a standard corresponding to LPWA. For example, the wireless communication standard to which the wireless communication unit 852 conforms may include SIGFOX, LoRaWAN, or NB-IoT.

[0262] When the fan 10 and the electric machine 850 are paired, the fan 10 and the electric machine 850 can wirelessly communicate with each other in accordance with Bluetooth. The fan 10 capable of wireless communication with the electric machine 850 may receive operation information related to the operation of the electric machine 850 from the electric machine 850 and control the motor 15 based on the received operation information.

[0263] For example, consider a case where a worker using an electric machine 850 works while wearing the fan garment 1. In this case, the electric machine 850 is paired with each of the fans 10 provided in the fan garment 1. This allows the electric machine 850 used by the worker and each of the fans 10 in the fan garment 1 worn by the worker to wirelessly communicate with each other in accordance with Bluetooth.

[0264] A control unit 851 of an electric machine 850 capable of wirelessly communicating with each fan 10 of the fan garment 1 generates operation start information as operation information when the operation of the electric machine 850 starts, in other words, when the motor 853 starts rotating. The operation start information is information indicating that the operation of the electric machine 850 has started. The wireless communication unit 852 transmits the operation start information generated by the control unit 851 to the fans 10.

[0265] Furthermore, when the operation of the electric machine 850 ends, in other words, when the rotation of the motor 853 stops, the control unit 851 generates operation end information as operation information. The operation end information is information indicating that the operation of the electric machine 850 has ended. The wireless communication unit 852 transmits the operation end information generated by the control unit 851 to the fan 10.

[0266] In the fan 10 that is paired with the electric machine 850 and in a power-on state, when the wireless communication unit 802 receives operation start information, the control unit 801 stops the rotation of the motor 15 and stops the rotation of the blade unit 14. When the wireless communication unit 802 subsequently receives operation end information, the control unit 801 rotates the motor 15 to rotate the blade unit 14. At this time, the control unit 801 may rotate the motor 15 after a predetermined time has elapsed since the wireless communication unit 802 received the operation end information. The predetermined time is set to, for example, about several minutes.

[0267] In this way, when the fan 10 receives the operation start information, the motor 15 stops rotating, so that the blades 14 of the fan 10 do not rotate when the electric machine 850 that generates dust during use is operating. If the blades 14 of the fan 10 rotate in a situation where dust is generated, the fan 10 may suck in the dust. If the fan 10 sucks in the dust, the fan 10 may break down. Furthermore, the dust may get into the inside 510 of the garment 2, causing discomfort to the worker wearing the garment 2. By not rotating the blades 14 of the fan 10 when the electric machine 850 is operating, the possibility of the fan 10 breaking down or the dust getting into the inside 510 of the garment 2 can be reduced.

[0268] Furthermore, by stopping the rotation of the motor 15 after a predetermined time has elapsed since the fan 10 received the operation end information, the blades 14 of the fan 10 rotate a predetermined time after the operation of the electric machine 850, which generates dust during use, ends. Since dust may remain in the air for a while after the operation of the electric machine 850 ends, if the blades 14 of the fan 10 rotate immediately after the operation of the electric machine 850 ends, the fan 10 may suck in dust. In the case where the blades 14 of the fan 10 rotate a predetermined time after the operation of the electric machine 850 ends as in this example, the possibility of the fan 10 sucking in dust can be reduced.

[0269] The operational information transmitted by the electric machine 850 to the fan 10 is not limited to the above example.

[0270] <Second operation example> The fan 10 according to this example is capable of controlling the motor 15 based on the detection results of the sensor. FIG. 43 is a block diagram mainly showing the electrical configuration of the fan 10 according to this example. As shown in FIG. 43, the fan 10 according to this example includes a temperature sensor 900 that detects the temperature of the air taken in by the fan 10. The temperature sensor 900 is disposed, for example, near an air inlet provided in a housing of the fan 10. The temperature sensor 900 repeatedly detects the temperature of the air taken in by the fan 10.

[0271] In this example, the control unit 161 controls the motor 15 based on the detection result of the temperature sensor 900. For example, the higher the temperature detected by the temperature sensor 900, the higher the rotation speed of the motor 15 the control unit 161 increases. As a result, the higher the temperature detected by the temperature sensor 900, the larger the airflow of the fan 10. Hereinafter, the temperature detected by the temperature sensor 900 may be referred to as the detected temperature.

[0272] When the detected temperature is low, the control unit 161 sets the rotation speed of the motor 15 to a first speed and sets the air volume of the fan 10 to "small". When the detected temperature is, for example, less than 15 degrees, the control unit 161 determines that the detected temperature is low. When the detected temperature is medium, the control unit 161 sets the rotation speed of the motor 15 to a second speed and sets the air volume of the fan 10 to "medium". When the detected temperature is, for example, 15 degrees or more and less than 25 degrees, the control unit 161 determines that the detected temperature is medium. When the detected temperature is high, the control unit 161 sets the rotation speed of the motor 15 to a third speed and sets the air volume of the fan 10 to "large". When the detected temperature is, for example, 25 degrees or more, the control unit 161 determines that the detected temperature is high. Every time the detected temperature is obtained by the temperature sensor 900, the control unit 161 sets the air volume of the fan 10 based on the detected temperature.

[0273] In this way, the motor 15 of the fan 10 is controlled based on the detection result of the temperature sensor 900, so that the motor 15 is appropriately controlled in accordance with the temperature of the air taken in by the fan 10.

[0274] 44, the fan 10 may include a humidity sensor 901 that detects the humidity of the air taken in by the fan 10. Like the temperature sensor 900, the humidity sensor 901 is disposed, for example, near an air inlet provided in a housing of the fan 10. The humidity sensor 901 repeatedly detects the humidity of the air taken in by the fan 10.

[0275] When fan 10 includes humidity sensor 901, control unit 161 may control motor 15 based on the detection result of humidity sensor 901. For example, the higher the humidity detected by humidity sensor 901, control unit 161 increases the rotation speed of motor 15. As a result, the higher the humidity detected by humidity sensor 901, the larger the air volume of fan 10. Hereinafter, the humidity detected by humidity sensor 901 may be referred to as detected humidity.

[0276] When the detected humidity is low, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "small". When the detected humidity is, for example, less than 85 degrees, the control unit 161 determines that the detected humidity is low. When the detected humidity is medium, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "medium". When the detected humidity is, for example, 85% or more and less than 90%, the control unit 161 determines that the detected humidity is medium. When the detected humidity is high, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "large". When the detected humidity is, for example, 90% or more, the control unit 161 determines that the detected humidity is high. Every time the detected humidity is obtained by the humidity sensor 901, the control unit 161 sets the air volume of the fan 10 based on the detected humidity.

[0277] In this way, the motor 15 of the fan 10 is controlled based on the detection result of the humidity sensor, so that the motor 15 is appropriately controlled according to the humidity of the air taken in by the fan 10.

[0278] As shown in FIG. 45, the fan 10 may include a temperature sensor 900 and a humidity sensor 901. In other words, the fan 10 may include a composite sensor including the temperature sensor 900 and the humidity sensor 901. In this case, the control unit 161 repeatedly calculates the discomfort index based on, for example, the temperature and humidity detected by the composite sensor. Then, every time the control unit 161 calculates the discomfort index, it controls the motor 15 based on the calculated discomfort index. For example, when the discomfort index is small, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "small". When the discomfort index is less than, for example, 70, the control unit 161 determines that the discomfort index is low. Also, when the discomfort index is medium, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "medium". When the discomfort index is equal to or greater than 70 and less than 80, for example, the control unit 161 determines that the discomfort index is medium. If the discomfort index is high, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "large." If the discomfort index is, for example, 80 or higher, the control unit 161 determines that the discomfort index is high.

[0279] In this way, the motor 15 of the fan 10 is controlled based on the detection results of a sensor that detects the temperature and humidity of the air taken in by the fan 10, so that the motor 15 is appropriately controlled according to the temperature and humidity of the air taken in by the fan 10.

[0280] 46, the fan 10 may include an acceleration sensor 902 that detects the acceleration of the fan 10. The acceleration sensor 902 is, for example, a three-axis acceleration sensor. The acceleration sensor 902 may be provided somewhere other than the substrate 160, or may be provided on the substrate 160. In the case where the fan 10 includes the acceleration sensor 902, the control unit 161 may control the motor 15 based on the detection result of the acceleration sensor 902. Hereinafter, the acceleration detected by the acceleration sensor 902 may be referred to as the detected acceleration.

[0281] The control unit 161 repeatedly calculates the amount of exercise per unit time of the user wearing the garment 2 to which the fan 10 is attached based on the detected acceleration. For example, the calorie consumption per unit time of the user is adopted as the amount of exercise per unit time of the user. When the amount of exercise per unit time is small, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "small". When the amount of exercise per unit time is medium, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "medium". When the amount of exercise per unit time is large, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "large". Each time the control unit 161 calculates the amount of exercise per unit time, it sets the air volume of the fan 10 based on the calculated amount of exercise.

[0282] In this way, the motor 15 of the fan 10 is appropriately controlled by being controlled based on the detection result of the acceleration sensor 902. Note that other information may be used as the amount of exercise of the user per unit time. For example, the number of steps taken by the user per unit time may be used as the amount of exercise of the user per unit time.

[0283] As shown in FIG. 47, the fan 10 may include a dust sensor 903 that detects dust taken in by the fan 10. The dust sensor 903 is disposed, for example, near an air inlet provided in a housing of the fan 10, similar to the temperature sensor 900 and the humidity sensor 901. The detection method of the dust sensor 903 may be optical or another method. The dust sensor 903 is also called a dust sensor. The dust sensor 903 repeatedly calculates and outputs, for example, the concentration of dust taken in by the fan 10. Hereinafter, the dust concentration output by the dust sensor 903 may be referred to as a detected dust concentration.

[0284] When the fan 10 includes a dust sensor 903, the control unit 161 may control the motor 15 based on the detection result of the dust sensor 903. FIG. 48 is a flowchart showing an example of the operation of the control unit 161 when the control unit 161 controls the motor 15 based on the detection result of the dust sensor 903.

[0285] As shown in Fig. 48, in step s1, the control unit 161 determines whether the detected dust concentration is high or not. For example, when the detected dust concentration is equal to or greater than a threshold value, the control unit 161 determines that the detected dust activity is high. On the other hand, when the detected dust concentration is less than the threshold value, the control unit 161 determines that the detected dust activity is low.

[0286] If it is determined in step s1 that the detected dust concentration is high, in step s2, the control unit 161 stops the rotation of the motor 15 for a predetermined time. The predetermined time is set to, for example, about one minute to several minutes. After stopping the rotation of the motor 15 for the predetermined time, the control unit 161 executes step s2 again. Thereafter, the control unit 161 operates in the same manner.

[0287] If it is determined in step s1 that the detected dust concentration is low, then in step s3, the control unit 161 rotates the motor 15. If the rotation of the motor 15 is stopped when step s3 is executed, then in step s3, the control unit 161 starts the rotation of the motor 15. On the other hand, if the motor 15 is rotating when step s3 is executed, then in step s3, the control unit 161 maintains the rotation of the motor 15. After step s3, the control unit 161 executes step s2 again. Thereafter, the control unit 161 operates in the same manner.

[0288] In this way, the motor 15 of the fan 10 is appropriately controlled by controlling the motor 15 based on the detection result of the dust sensor 903. In addition, in step s1, the control unit 161 may determine whether or not the state in which the detected dust concentration is high continues for a predetermined time or more.

[0289] The fan 10 may include two or more sensors selected from the temperature sensor 900, the humidity sensor 901, the acceleration sensor 902, and the dust sensor 903. In other words, the fan 10 may be a composite sensor including two or more sensors selected from the temperature sensor 900, the humidity sensor 901, the acceleration sensor 902, and the dust sensor 903. The fan 10 may also include at least one of the temperature sensor 900, the humidity sensor 901, the acceleration sensor 902, and the dust sensor 903, and the wireless communication unit 852 described above.

[0290] As described above, the fan garment 1 and the fan 10 have been described in detail, but the above description is merely illustrative in all respects, and this disclosure is not limited thereto. Furthermore, the various examples described above can be combined and applied as long as they are not mutually inconsistent. It is understood that countless examples not illustrated can be envisioned without departing from the scope of this disclosure. [Explanation of symbols]
