Embodiments for Carrying Out the Invention

[0006] FIG. 1 is a diagram showing the appearance of a piece of clothing 1 with a fan. As shown in FIG. 1, the piece of clothing 1 with a fan includes a piece of clothing 2 and a fan 10 for clothing attached to the piece of clothing 2. The fan 10 for clothing is, for example, an axial flow fan. FIG. 2 is a diagram showing the appearance of the piece of clothing 2. In FIGS. 1 and 2, the back side of the piece of clothing 2 is shown.

[0007] As shown in Figure 1, the garment fan 10 is attached, for example, to the lower part of the back 3 of the garment 2. As shown in Figure 2, the lower part of the back 3 of the garment 2 is provided with mounting holes 4 for attaching the garment fan 10 to the garment 2. The garment fan 10 is attached to the mounting holes 4. In this example, the lower part of the back 3 of the garment 2 is provided with two mounting holes 4 side by side. The garment fan 10 is attached to each mounting hole 4. As will be described later, since the garment fan 10 is attached to the garment 2 so as to sandwich the peripheral edge 5 of the mounting hole 4, the peripheral edge 5 is reinforced. Hereafter, the garment fan 10 may be simply referred to as the fan 10.

[0008] Each fan 10 takes in air from one side and expels the air it has taken in from the other side. Each fan 10 is attached to the garment 2 such that the side that takes in air (i.e., the intake side) is on the outside of the garment 2 and the side that expels air (i.e., the exhaust side) is 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 mounting holes 4. The air taken in to the inside of the garment 2 is expelled to the outside of the garment 2 through the cuffs and neckline of the garment 2 by the operation of each fan 10. This makes it possible to cool the body of the person wearing the garment 2. The mounting holes 4 of the garment 2 become intake vents for the cooling air, and the cuffs and neckline of the garment 2 become exhaust vents for the cooling air.

[0009] The number of fans 10 attached to the garment 2 may be one or three or more. Furthermore, the mounting positions of the fans 10 on the garment 2 are not limited to the examples shown in Figures 1 and 2.

[0010] The following describes various structural examples of the fan 10. When multiple fans 10 are attached to the garment 2, these multiple fans 10 may include multiple fans 10 having the same structure, or multiple fans 10 having different structures. Hereafter, the side of the fan 10 that takes in air will be referred to as the front, and the side of the fan 10 that expels air will be referred to as the rear, and the structure of the fan 10 will be described accordingly. Furthermore, when the fan 10 is attached to the garment 2, the neck side of the garment 2 will be referred to as the upper side of the fan 10, and the hem side of the garment 2 will be referred to as the lower side of the fan 10, and the structure of the fan 10 will be described accordingly.

[0011] <First structural example> Figures 3-6 show an example of the structure of the fan 10 (sometimes called fan 10A) in this example. Figure 3 shows the fan 10A viewed from the front, and Figure 4 shows the fan 10A viewed from the rear. Figures 5 and 6 show the internal structure of the fan 10A. In Figures 5 and 6, hatching is shown in the cross-section. Figure 5 shows the fan 10A attached to the garment 2. The left side of the garment 2 in Figure 5 shows the outside 500 of the garment 2, and the right side of the garment 2 in Figure 5 shows the inside 510 of the garment 2 (in other words, the side closer to the human body than the garment 2). Also, the top of Figure 5 shows the neck side of the garment 2, and the bottom of Figure 5 shows the hem side of the garment 2. Similarly, in the diagram showing the internal structure of the fan 10 attached to the garment 2, which will be described later, hatching is shown in the cross-section, and the left and right sides of the garment 2 show the outside 500 and inside 510 of the garment 2, respectively, and the top and bottom of the diagram show the neck side and hem side of the garment 2, respectively. The fan 10A can be attached to clothing 2, or it can be used standing on a desk or the like, as shown in Figure 6. Figure 7 is a perspective view showing an example of the appearance of the fixing member 11 of the fan 10A. Figure 8 is a block diagram mainly showing the electrical configuration of the fan 10A.

[0012] As shown in Figures 3-8, the fan 10A comprises a main body 12 and a fixing member 11 for fixing the main body 12 to the clothing 2. The main body 12 comprises a housing 13, a fan blade 14, a motor 15, a circuit board 16, a battery 17, and a stand member 18 for standing the fan 10A upright. The fan blade 14, motor 15, circuit board 16, and battery 17 are housed in the housing 13. The fixing member 11 can also be said to be a member for fixing the housing 13 to the clothing 2.

[0013] The housing 13 is made of, for example, resin. The external shape of the housing 13 is approximately circular, whether viewed from the front or the back. The housing 13 comprises a front portion 130, a rear portion 131, and a cover portion 132.

[0014] The front portion 130 has a roughly circular shape when viewed from the front. The front portion 130 comprises a front section 130a, a cylindrical section 130b, and a flange section 130c. The front section 130a is provided with multiple air intake ports 130aa. The front section 130a can be described as an air intake section that draws air from outside the housing 13 into the housing 13. Hereafter, the front section 130a may be referred to as the air intake section 130a.

[0015] The cylindrical portion 130b is provided on the periphery of the front portion 130a, surrounding it and protruding backward from that periphery. The flange portion 130c is provided on the periphery of the front portion 130a, surrounding it. The flange portion 130c protrudes radially from the periphery of the front portion 130a. As shown in Figure 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 rear portion 131 has a roughly circular shape when viewed from the rear. The rear portion 131 comprises a rear section 131a and a cylindrical section 131b. The cylindrical section 131b surrounds the periphery of the rear section 131a and is provided on the periphery so as to protrude forward from that periphery. Multiple exhaust ports 131c are provided in the rear section 131a and the cylindrical section 131b. The rear section 131a and the cylindrical section 131b can be said to be exhaust sections that exhaust air to the outside of the housing 13. The multiple exhaust ports 131c are provided avoiding the central part of the rear section 131a. The cylindrical section 130b of the front portion 130 and the cylindrical section 131b of the rear portion 131 are connected to each other and constitute the cylindrical peripheral wall (in other words, the side section) 135 of the entire housing 13. As the blade section 14 rotates, air is drawn into the housing 13 from the intake port 130aa, and the air drawn into the housing 13 is exhausted to the outside of the housing 13 from the exhaust port 131c.

[0017] A male threaded portion 130bb is formed on the outer circumferential surface of the cylindrical portion 130b of the front portion 130, which engages with the female threaded portion 110a of the fixing member 11, as described later. A recess 130ab is provided on the outer surface (in other words, the front surface) of the front portion 130a. The motor 15, circuit board 16, and battery 17 are fixed to the recess 130ab. Multiple air intake ports 130aa are provided on the front portion 130a in areas other than 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 to the rear. A holding portion 130f for holding the stand member 18 is provided on the lower part 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 the pivot point.

[0018] The cover portion 132 is attached to the front portion 130a so as to cover the recess 130ab. As a result, the motor 15, circuit board 16, and battery 17 within the recess 130ab are covered by the cover portion 132. In the housing 13, the recess 130ab and the cover portion 132 that covers it form a housing space 133 for housing the motor 15, circuit board 16, and battery 17. In the housing space 133, the circuit board 16 is positioned opposite the motor 15. There are no components 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 portion 132 comprises a first portion 132a that covers the circuit board 16 and a second portion 132b that covers the battery 17. The second portion 132b is curved outward according to the outer shape of the battery 17.

[0019] The front portion 130 and the rear portion 131 constitute a housing space 134 for housing the blade portion 14. The blade portion 14 comprises a plurality of blades 140 and a connecting portion 141 that connects the plurality of blades 140. The connecting portion 141 is cylindrical with one end almost closed and covers the protrusion 130ac of the front portion 130a. The rotating shaft 150 of the motor 15 in the recess 130ab extends to the outside of the protrusion 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] Motor 15 is, for example, a DC motor. Motor 15 is driven by a circuit board 16. Motor 15 is electrically connected to the circuit board 16 by lead wires 19. Battery 17 supplies power to the circuit board 16. Battery 17 is, for example, a cylindrical battery. Battery 17 may be a rechargeable secondary battery or a non-rechargeable primary battery. Battery 17 and the circuit board 16 are electrically connected by lead wires.

[0021] As shown in Figure 8, the circuit board 16 comprises a substrate 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 substrate 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. Furthermore, the control unit 161 can 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 supplied to the motor 15. As the rotation speed of the motor 15 changes, the airflow of the fan 10A changes. By controlling the motor 15, the control unit 161 can set the airflow of the fan 10A to, for example, three levels: "high," "medium," and "low." Note that the airflow setting of the fan 10A may be set to two levels, or to four or more levels.

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

[0024] According to various embodiments, at least one processor may be implemented as a single integrated circuit (IC) or as a plurality of communicably connected integrated circuits (ICs) and / or discrete circuits. At least one processor can be implemented according to various known techniques.

[0025] In one embodiment, the processor includes one or more circuits or units configured to perform one or more data computation procedures or processes by, for example, executing instructions stored in associated memory. In other embodiments, the 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 processing devices, programmable logic devices, field-programmable gate arrays, or any combination of these devices or configurations, or other known combinations of devices and configurations, and may perform the functions described below.

[0027] The display unit 162 is capable of displaying the operating status 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 individually illuminate or individually stop each light-emitting unit 162a. The plurality of light-emitting units 162a include, as shown in Figure 3, a plurality of light-emitting units 162aa, 162ab, 162ac that indicate the remaining charge of the battery 17, and a plurality of light-emitting units 162ad, 162ae, 162af that indicate the airflow of the fan 10A. The light-emitting units 162aa, 162ab, 162ac, 162ad, 162ae, 162af are exposed from the front surface of the housing 13. Specifically, the light-emitting units 162aa, 162ab, 162ac, 162ad, 162ae, 162af are exposed from the first part 132a of the cover part 132 of the housing 13. The display unit 162 is exposed from an area visible from the intake side of the housing 13.

[0028] The control unit 161 can determine 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 illuminates all of the multiple light-emitting units 162aa, 162ab, and 162ac. When the remaining charge of the battery 17 is about half, the control unit 161 illuminates 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 illuminates 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 of the fan 10A to "low", it illuminates only the light-emitting part 162ad among the light-emitting parts 162ad, 162e, and 162f. When the control unit 161 sets the airflow of the fan 10A to "medium", it illuminates only the light-emitting part 162ae among the light-emitting parts 162ad, 162ae, and 162af. When the control unit 161 sets the airflow of the fan 10A to "high", it illuminates only the light-emitting part 162af among the light-emitting parts 162ad, 162ae, and 162af.

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

[0031] The operation button 163a functions, for example, as a power button. When the fan 10A is powered off and the operation button 163a is pressed for a predetermined time or longer, the fan 10A is powered on. Conversely, when the fan 10A is powered on and the operation button 163a is pressed for a predetermined time or longer, the fan 10A is powered off. The predetermined time is set to, for example, 1 to 2 seconds. Hereafter, 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 powered off, most of the functions of the control unit 161 are stopped. When the fan 10A is powered off, the control unit 161 operates, for example, the function for identifying the operation of the operation button 163a, and the functions for controlling the motor 15 and the display unit 162 are stopped. Therefore, when the fan 10A is powered off, the motor 15 does not rotate, and the light-emitting parts 162a of the display unit 162 do not light up. When the fan 10A changes from a powered-off state to a powered-on state, the motor 15 rotates, and the display unit 162 displays information. On the other hand, when the fan 10A changes from a powered-on state to a powered-off state, the rotation of the motor 15 stops, and the display of the display unit 162 turns off. The control unit 161 can turn the fan 10A powered off or powered on.

[0033] The operation button 163a also functions as an adjustment button for adjusting the airflow of the fan 10A. When the fan 10A is powered on, the airflow 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. Hereafter, the operation in which the operation button 163a is pressed for less than a predetermined time and then the pressure on the operation button 163a is released may be referred to as a short press operation.

[0034] If the fan 10A's airflow is set to "low," a short press of the operation button 163a will cause the control unit 161 to increase the rotation speed of the motor 15 and set the fan 10A's airflow to "medium." If the fan 10A's airflow is set to "medium," a short press of the operation button 163a will cause the control unit 161 to increase the rotation speed of the motor 15 and set the fan 10A's airflow to "high." If the fan 10A's airflow is set to "high," a short press of the operation button 163a will cause the control unit 161 to decrease the rotation speed of the motor 15 and set the fan 10A's airflow to "low."

[0035] The display unit 162 may also include a segment-type or dot-matrix 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] The operation unit 163 may be equipped with multiple operation buttons 163a. ​​Furthermore, if the display unit 162 is equipped with a dot matrix display, the operation unit 163 may be equipped with software buttons displayed on the dot matrix display, either in place of the operation buttons 163a or in addition to the operation buttons 163a.

[0037] The fixing member 11 is a ring-shaped member for securing the main body 12 to the clothing 2. The fixing member 11 includes a ring-shaped mounting portion 110 that is attached to the main body 12. The inner circumferential surface of the mounting portion 110 is provided with a female screw portion 110a that screws into the male screw portion 130bb of the front portion 130 of the housing 13. Furthermore, the fixing member 11 includes a flange portion 111 that surrounds the outer surface of the mounting portion 110 and protrudes radially from the outer circumferential surface of the fixing member 11. The flange portion 111 is provided at the front end of the outer surface of the mounting portion 110.

[0038] The stand member 18 is a support member for holding the fan 10A upright, capable of supporting the housing 13. As shown in Figure 3, the stand member 18 is a roughly U-shaped rod. The stand member 18 includes a held portion 180 which is held by the holding portion 130f of the housing 13. The held portion 180 is straight. Furthermore, the stand member 18 includes a pair of support portions 181 which are capable of supporting the housing 13 when the fan 10A is held upright, as shown in Figure 6. The pair of support portions 181 extend in a roughly curved manner from both ends in the longitudinal direction of the held portion 180, facing 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 clothing 2, the stand member 18 is positioned 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 stand member 18 is positioned so that the pair of support parts 181 are far away from the front surface of the housing 13, as shown in Figure 6. As shown in Figure 6, when the fan 10A is placed upright, the pair of support parts 181 support the housing 13 so that it does not fall over. The arrow 9A shown in Figure 6 indicates the direction in which the air flows when the fan blades 14 of the fan 10A rotate.

[0040] When the fan 10A, having the configuration described above, 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 does not pass through the mounting hole 4, but instead comes into contact with the outer surface 500 of the peripheral edge 5 of the mounting hole 4 of the garment 2.

[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 contacts the inner surface 510 of the peripheral edge 5 of the garment 2. Specifically, the fixing member 11 is attached to the front portion 130 so that the flange portion 111 contacts the inner surface 510 of the peripheral edge 5, and the female thread portion 110a on the inner surface of the fixing member 11 is screwed into the male thread portion 130bb on the outer surface of the cylindrical portion 130b that protrudes from the inside 510 of the garment 2. Then, as the fixing member 11 is tightened clockwise when viewed from the inside 510 of the garment 2, the flange portion 130c of the front portion 130 and the flange portion 111 of the fixing member 11 grip the peripheral edge 5 of the garment 2. This fixes the fan 10A to the garment 2. When the blade portion 14 of the fan 10A fixed to the garment 2 rotates, air from the outside 500 of the garment 2 is drawn into the inside 510 of the garment 2 through the intake port 130aa and the exhaust port 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 removed from the mounting hole 4.

[0043] Note that the fan 10A does not necessarily have to include a stand member 18 and a holding part 130f that holds it.

[0044] Thus, 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 wires connecting the battery 17 and the circuit board 16) can be shortened. Therefore, the possibility of damage to the wiring can be reduced. As a result, the possibility of malfunction of the fan 10A can be reduced.

[0045] Furthermore, in this example, since a cable is not required to connect the battery and the fan unit, it becomes easier to attach the fan 10A to clothing 2.

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

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

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

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

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

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

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

[0053] Furthermore, in this example, when the fan 10A is viewed from the intake side, the battery 17 overlaps with the fan blades 14. This makes it possible to reduce the size of the fan 10A when viewed from the intake side.

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

[0055] Furthermore, if the battery 17 is a rechargeable secondary battery, a charging terminal for supplying a charging voltage to the battery 17 may be provided on the fan 10A. The charging terminal may be a USB (Universal Serial Bus) terminal or a terminal for connecting to an AC adapter. Similarly, a charging terminal may also be provided on the fan 10, which has a different structure from the fan 10A and will be described later.

[0056] <Second structural example> Figures 9-12 show examples of the external appearance of the fan 10 (sometimes called fan 10B) in this example. Figure 9 shows the fan 10B viewed from the front. Figures 10 and 11 show the fan 10B viewed from the rear. Figure 12 shows the internal structure of the fan 10B. Figure 12 shows the fan 10B attached to the garment 2.

[0057] As shown in Figures 9-12, the fan 10B comprises a main body 22 and the aforementioned fixing member 11 for fixing the main body 22 to the clothing 2. The main body 22 comprises a housing 23 and the aforementioned blades 14, motor 15, circuit board 16, and battery 17. The blades 14, motor 15, circuit board 16, and battery 17 are housed in the housing 23.

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

[0059] The front portion 230 comprises a first portion 2300 that covers the front surface of the blade portion 14 and a second portion 2310 located below the first portion 2300. The first portion 2300 has a plurality of air intake ports 2301a, while the second portion 2310 does not have air intake ports. The first portion 2300 is connected to the rear portion 231 and forms a housing space 237 for housing the blade portion 14 with the rear portion 231. The second portion 2310 is connected to the second cover portion 233 and forms a housing space 236 for housing the circuit board 16 and the battery 17 with the second cover portion 233.

[0060] The outer shape of the first part 2300 is approximately circular when viewed from the front. The first part 2300 comprises a front section 2301 with a plurality of air intake ports 2301a, a cylindrical section 2302, and a flange section 2303. The front section 2301 can be described as an air intake section that draws air from outside the housing 23 into the housing 23. The plurality of air intake ports 2301a are provided on the front section 2301, avoiding its central part. Hereafter, the front section 2301 may be referred to as the air intake section 2301.

[0061] The cylindrical portion 2302 is provided on the periphery of the front portion 2301, surrounding it and protruding backward from the periphery. A male threaded portion 2302a is formed on the outer circumferential surface of the cylindrical portion 2302, which engages with the female threaded portion 110a of the fixing member 11. The flange portion 2303 is provided on the periphery of the front portion 2301, substantially surrounding it. The flange portion 2303 protrudes radially from the periphery of the front portion 2301.

[0062] The second part 2310 extends downward from the lower part of the flange portion 2303. The circuit board 16 and the battery 17 are fixed to the second part 2310. The battery 17 is located below the circuit board 16. The second part 2310 comprises 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 according to the outer shape of the battery 17.

[0063] The rear portion 231 has a roughly circular shape when viewed from the rear. The rear portion 231 comprises a rear section 231a and a cylindrical section 231b. The cylindrical section 231b surrounds the periphery of the rear section 231a and is provided on the periphery so as to protrude forward from that periphery. Multiple exhaust ports 231c are provided in the rear section 231a and the cylindrical section 231b. The rear section 231a and the cylindrical section 231b can be described as exhaust sections that exhaust air to the outside of the housing 23.

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

[0065] A recess 231aa is provided in the center of the outer surface of the rear portion 231a of the rear section 231. The motor 15 is fixed to the recess 231aa. A protrusion 231ab corresponding to the recess 231aa is provided on the inner surface of the rear portion 231a. The connecting portion 141 of the blade portion 14 covers the protrusion 231ab. The rotation 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. In the front portion 2301 of the first section 2300, a plurality of air intake ports 2301a are provided, avoiding the portion facing the connecting portion 141 of the blade portion 14.

[0066] The first cover portion 232 is attached to the rear portion 231a of the rear portion 231 so as to cover the recess 231aa. As a result, the motor 15 inside the recess 231aa is covered by the first cover portion 232. In the housing 23, the recess 231aa and the first cover portion 232 covering it form a housing space 238 for housing the motor 15.

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

[0068] As shown in Figure 9, the light-emitting parts 162aa, 162ab, 162ac, 162ad, 162ae, and 162af of the display unit 162 of the circuit board 16 are exposed from the front surface of the substrate-side portion 2311 of the second portion 2310. In addition, the operation button 163a of the operation unit 163 of the circuit board 16 is exposed from the front surface of the substrate-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 does not pass through the mounting hole 4 but comes into contact with the outer surface 500 of the peripheral edge 5 of the mounting hole 4 of the garment 2. Also, the second portion 2310 of the front portion 230 does not pass through the mounting hole 4 but is located on the outside 500 of the garment 2.

[0070] Next, the fixing member 11 is attached to the housing 23 from the inside 510 of the garment 2 such that the flange portion 111 of the fixing member 11 contacts the inner surface 510 of the peripheral edge 5 of the garment 2. Specifically, the fixing member 11 is attached to the first portion 2300 of the front portion 230 such that the flange portion 111 contacts the inner surface 510 of the peripheral edge 5, and the female threaded portion 110a of the fixing member 11 is screwed into the male threaded portion 2302a of the cylindrical portion 2302 protruding from the inside 510 of the garment 2. Then, as the fixing member 11 is tightened clockwise when viewed from the inside 510 of the garment 2, the flange portion 2303 of the front portion 230 and the flange portion 111 of the fixing member 11 clamp the peripheral edge 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 5 of the garment 2. This fixes the fan 10B to the garment 2. When the blade portion 14 of the fan 10B fixed to the garment 2 rotates, air from the outside 500 of the garment 2 is drawn into the inside 510 of the garment 2 through the intake port 2031a and 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 removed from the mounting hole 4.

[0072] Thus, in this example, similar to the first structural example, since the battery 17 is located inside the housing 23, the wiring extending from the battery 17 can be shortened. Therefore, the possibility of damage to the wiring can be reduced. As a result, the possibility of malfunction of the fan 10B can be reduced.

[0073] Furthermore, in this example, since a cable is not required to connect the battery and the fan unit, it becomes easier to attach the fan 10B to the garment 2.

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

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

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

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

[0078] Furthermore, in this example, when the fan 10B is viewed from the intake side, the operating section 163 is located outside the intake section 2301. This reduces the possibility that the operating section 163 may obstruct the intake of the fan 10B. Therefore, the performance of the fan 10B is improved.

[0079] Furthermore, in this example, when the fan 10B is viewed from the intake side, the battery 17, which is covered by the second portion 2310 of the housing 23, is located outside the intake section 2301. This reduces the possibility that the battery 17 may obstruct the intake of the fan 10B. Therefore, the performance of the fan 10B is improved.

[0080] In this example, since the circuit board 16 is located below the motor 15, when viewed from the intake side, the circuit board 16 does not have a portion facing the motor 15. In contrast, in the fan 10A according to the first structural example described above, when viewed from the intake side, the circuit board 16 has a portion facing the motor 15. By having the circuit board 16 have a portion facing the motor 15, the size of the fan 10 when viewed from the front can be reduced.

[0081] <Third structural example> Figures 13-16 show an example of the structure of the fan 10 (sometimes called fan 10C) in this example. Figure 13 shows the fan 10C viewed from the front. Figures 14 and 15 show the fan 10C viewed from the rear. Figure 16 shows the internal structure of the fan 10C. Figure 16 shows the fan 10C attached to the garment 2.

[0082] As shown in Figures 13-16, the fan 10C comprises a housing 33 and the aforementioned fan blades 14, motor 15, circuit board 16, and battery 17. The fan blades 14, motor 15, circuit board 16, and battery 17 are housed in the housing 33.

[0083] The housing 33 is made of, for example, resin. The housing 33 comprises 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] The rear portion 331 is used to fix the blades 14, motor 15, circuit board 16, and battery 17. The rear portion 331 can be described as a holding portion that holds the blades 14, motor 15, circuit board 16, and battery 17. The front portion 330 is detachable from the rear portion 331. The front portion 330 functions as a fixing portion for fixing the rear portion 331, which holds the blades 14, etc., to the clothing 2. Hereafter, the rear portion 331 may be referred to as the holding portion 331. The front portion 330 may also be referred to as the fixing portion 330.

[0085] The outer shape of the fixed part 330 is approximately circular when viewed from the front. The fixed part 330 comprises a front part 330a, a cylindrical part 330b, and a flange part 330c. Multiple air intake ports 330aa are provided on the front part 330a, avoiding its central part. The front part 330a can be said to be an air intake section that takes in air from outside the housing 33 into the housing 33. Hereafter, the front part 330a may be referred to as the air intake section 330a.

[0086] The cylindrical portion 330b is provided on the periphery of the front portion 330a, surrounding it and protruding backward from the periphery. A male threaded portion 330bb is formed on the outer circumferential surface of the cylindrical portion 330b, which screws into the female threaded portion 3312a of the retaining portion 331, described later. The flange portion 330c is provided on the periphery of the front portion 330a, surrounding it. The flange portion 330c protrudes radially from the periphery of the front portion 330a.

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

[0088] The outer shape of the first retaining portion 3310 is approximately circular when viewed from the rear. The first retaining portion 3310 comprises a rear portion 3311, a cylindrical portion 3312, and a flange portion 3313. The cylindrical portion 3312 surrounds the periphery of the rear portion 3311 and is provided on the periphery so as to protrude forward from that periphery. Multiple exhaust ports 3314 are provided in the rear portion 3311 and the cylindrical portion 3312. The rear portion 3311 and the cylindrical portion 3312 can be said to be exhaust portions that discharge air to the outside of the housing 33. A female threaded portion 3312a is formed on the inner circumferential surface of the cylindrical portion 3312, which screws into the male threaded portion 330bb of the fixing portion 330. The cylindrical portion 330b of the fixing portion 330 and the cylindrical portion 3312 of the holding portion 331 are connected to each other by the screwing of the male thread portion 330bb and the female thread portion 3312a, forming the cylindrical peripheral wall portion (in other words, the side portion) 335 of the entire housing 33. When the vane portion 14 rotates, air is drawn into the housing 33 from the intake port 330aa, and the air drawn into the housing 33 is exhausted to the outside of the housing 33 from the exhaust port 3314.

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

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

[0091] The second holding portion 3320 comprises a first portion 3321 on which lead wires 19 connecting the motor 15 and the circuit board 16 are arranged, 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 close the recess 3311b of the rear portion 3311 of the first holding portion 3310 and the opening on the rear side of the second holding portion 3320. As a result, the motor 15 in the recess 3311b and the lead wires 19, circuit board 16 and battery 17 in the second holding portion 3320 are covered by the cover portion 332. The cover portion 332 comprises a first portion 332a that covers the motor 15, a second portion 332b that covers the lead wires 19, and a third portion 332c that covers the circuit board 16 and battery 17.

[0093] As shown in Figure 14, the light-emitting parts 162aa, 162ab, 162ac, 162ad, 162ae, and 162af of the display unit 162 of the circuit board 16 are exposed from the rear surface of the portion 332cc of the third part 332c of the cover unit 332 that faces the circuit board 16. In addition, the operation button 163a of the operation unit 163 of the circuit board 16 is exposed from the rear surface of the portion 332cc of the third part 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 cylindrical portion 3312 of the first retaining 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 retaining portion 3310 does not pass through the mounting hole 4, but instead contacts the inner surface 510 of the peripheral edge 5 of the mounting hole 4 of the garment 2. Also, the second portion 3322 of the second retaining portion 3320 does not pass through the mounting hole 4, but is located on the inside 510 of the garment 2.

[0095] Next, the fixing part 330 is attached to the holding part 331 from the outside 500 of the garment 2 such that the flange portion 330c of the fixing part 330 contacts the outer surface 500 of the peripheral edge 5 of the garment 2. Specifically, the fixing part 330 is attached to the first holding part 3310 of the holding part 331 such that the flange portion 330c contacts the outer surface 500 of the peripheral edge 5, and the male threaded portion 330bb of the cylindrical portion 330 of the fixing part 330 is screwed into the female threaded portion 3312a of the cylindrical portion 3312 of the holding part 331. Then, as the fixing part 330 is tightened clockwise when viewed from the outside 500 of the garment 2, the flange portion 330c of the fixing part 330 and the flange portion 3313 of the first holding part 3310 grip the peripheral edge 5 of the garment 2. Furthermore, the portion of the second holding portion 3320 located below the cylindrical portion 3312 of the first holding portion 3310, and the flange portion 330c of the fixing portion 330, grip the lower portion of the peripheral edge 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 from the outside 500 of the garment 2 is drawn 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 cylindrical part 3312 of the holding part 331 is removed from the mounting hole 4.

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

[0098] Thus, in this example, similar to the first structural example, since the battery 17 is located inside the housing 33, the wiring extending from the battery 17 can be shortened. Therefore, the possibility of damage to the wiring can be reduced. As a result, the possibility of malfunction of the fan 10C can be reduced.

[0099] Furthermore, in this example, since a cable is not required to connect the battery and the fan unit, it becomes easier to attach the fan 10C to the garment 2.

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

[0101] 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, as in the first and second structural examples described above, if the fixing member 11 is attached to the housing from the inside 510 of the garment 2, the user may find it difficult to attach the fixing member 11 to the housing from the inside 510 of the garment 2 while wearing the garment 2, as their own body gets in the way. In this example, since the user can attach the fixing part 330 to the holding part 331 from the outside 500 of the garment 2, it becomes easier to attach the fan 10C to the garment 2 even while 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 damage to the operating unit 163 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 damage to the display unit 162 can be reduced.

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

[0105] Furthermore, in this example, when the fan 10C is viewed from the intake side, the battery 17, which is covered by the second retaining portion 3320 of the housing 33, is located outside the intake portion 330a. This reduces the possibility that the battery 17 may obstruct the intake of the fan 10C. Therefore, the performance of the fan 10C is improved.

[0106] Furthermore, in this example, when the fixing part 330 is attached to the holding part 331, it covers the front surface of the blade part 14. Therefore, by removing the fixing part 330 from the holding part 331, the front surface of the blade part 14 is no longer covered by the components of the housing 33. Thus, cleaning of the blade part 14 becomes easier. For example, if the fan-equipped garment 1 is used in a dusty work environment, dust may adhere to the blade part 14. By removing the fixing part 330 from the holding part 331, the dust attached to the blade part 14 can be easily removed.

[0107] <Fourth structural example> Figures 17-22 show an example of the structure of the fan 10 (sometimes called fan 10D) in this example. Figure 17 shows the fan 10D viewed from the front, and Figures 18 and 19 show the fan 10D viewed from the rear. Figures 20-22 show the internal structure of the fan 10D. Figure 20 shows the fan 10D attached to the garment 2. The fan 10D can be attached to the garment 2, used standing on a desk or the like as shown in Figure 21, or used suspended from a rod-shaped or hook-shaped member 91 as shown in Figure 22.

[0108] As shown in Figures 17-22, the fan 10D comprises a main body 42 and a fixing member 21 for securing the main body 42 to the clothing 2. The main body 42 comprises a housing 43, the aforementioned blades 14, motor 15, circuit board 16, and battery 17, and a ring-shaped support member 28. The blades 14, motor 15, circuit board 16, and battery 17 are housed in the housing 43.

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

[0110] The front portion 430 comprises a front section 430a, a cylindrical section 430b, and a flange section 430c. When viewed from the front, the front section 430a has a roughly circular shape. Multiple air intake ports 430aa are provided in the front section 430a. The front section 430a can be described as an air intake section that draws air from outside the housing 43 into the housing 43. Hereafter, the front section 430a may be referred to as the air intake section 430a.

[0111] The cylindrical portion 430b is provided on the periphery of the front portion 430a, surrounding the periphery and protruding rearward from the periphery. The cylindrical portion 430b comprises a cylindrical front portion 430ba and a cylindrical rear portion 430bb. In the rear portion 430bb, there is a gap in the lower part, and the rear portion 430bb is not a perfect cylinder. A male threaded portion 430baa is formed on the outer circumferential surface of the front portion 430baa, which screws into the female threaded portion 210a of the fixing member 21, as described later. The flange portion 430c is provided on the periphery of the front end of the rear portion 430bb of the cylindrical portion 430b, surrounding the cylindrical portion 430b. The flange portion 430c protrudes radially from the periphery of the rear portion 430bb of the cylindrical portion 430b.

[0112] The rear portion 431 has an outer shape that is approximately circular when viewed from the rear. The rear portion 431 comprises a rear surface portion 431a and a cylindrical portion 431b. The cylindrical portion 431b surrounds the periphery of the rear surface portion 431a and is provided on the periphery so as to protrude forward from that periphery. Multiple exhaust ports 431c are provided in the rear surface portion 431a and the cylindrical portion 431b. The multiple exhaust ports 431c are provided so as to avoid the central part of the rear surface 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 the third portion 432c of the first holding portion 432 (described later) constitute the cylindrical peripheral wall portion (in other words, the side portion) 435 of the entire housing 43. In this example, the fan blades 14, motor 15, and circuit board 16 are located in a housing space 436 surrounded by a peripheral wall 435. When the fan blades 14 rotate, air is drawn into the housing 43 from the intake port 430aa, and the air drawn into the housing 43 is exhausted to the outside of the housing 43 from the exhaust port 431c.

[0113] The first holding portion 432 comprises a first part 432a that holds the motor 15 and the circuit board 16, a second part 432b that holds the battery 17, and a third part 432c that forms part of the lower portion of the peripheral wall 435. The front side of the first holding portion 432 is open. The third part 432c is located in the 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 part 432a is located within the housing space 436. The first part 432a extends downward from the center when the housing space 436, surrounded by the peripheral wall 435, is viewed from the front or rear, to the third part 432c, which is part of the peripheral wall 435. The first part 432a includes a motor holder 432aa that protrudes to the rear and holds the motor 15. The connecting portion 141 of the blade portion 14 covers the motor holder 432aa. The rotation shaft 150 of the motor 15 extends to the outside of the motor holder 432aa and is connected to the connecting portion 141 of the blade portion 14. The second part 432b is connected to the third part 432c and is located below the peripheral wall 435. The second part 432b is curved to the rear according to the shape of the battery 17.

[0115] The cover portion 433 is integrally molded with the front portion 430. The cover portion 433 comprises a first portion 433a that closes the front opening of the first portion 432a of the first retaining portion 432, and a second portion 433b that closes the front opening of the second portion 432b of the first retaining portion 432. The first portion 433a covers the motor 15 and 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 is located below the cylindrical portion 430b. The upper end of the second portion 433b constitutes part of the flange portion 430c.

[0116] As shown in Figure 17, the light-emitting parts 162aa, 162ab, 162ac, 162ad, 162ae, and 162af of the display unit 162 of the circuit board 16 are exposed from the front surface of the first portion 433a of the cover unit 433. In addition, the operation button 163a of 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 securing the main body 42 to the garment 2 has the same structure as 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 mounting portion 210 that is attached to the housing 43 of the main body 42. The inner circumferential surface of the mounting 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 surrounds the outer surface of the mounting portion 210 and protrudes radially from the outer circumferential surface of the fixing member 21. The flange portion 211 is provided at the rear end of the outer surface of the mounting 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 molded with the cover portion 433. The second holding portion 434 is located below the center of the front portion 430a. As shown in Figure 21, when the fan 10D is used upright, the support member 28 supports the fan 10D to prevent it from falling over. The support member 28 can be said to be a support member for placing the fan 10D upright, capable of supporting the housing 43. On the other hand, as shown in Figure 22, when the fan 10D is used suspended, the support member 28 functions as a suspension member for suspending the fan 10D from a rod-shaped member or a hook-shaped member, etc.

[0119] The support member 28 comprises two opposing linear portions 28a and 28b, and two opposing curved portions 28c and 28d. The curved portion 28c extends outward in a curved manner from one longitudinal end of the linear portion 28a to one longitudinal end of the linear portion 28b. The curved portion 28c extends outward in a curved manner from the other longitudinal end of the linear portion 28a to the other longitudinal end of the linear portion 28b. 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 positioned so as shown in Figures 17 and 20 that it faces the front surface of the front portion 430a of the housing 43.

[0121] Furthermore, when the fan 10D is placed upright on a desk or the like, as shown in Figure 21, the support member 28 is positioned such that the straight portion 28b and the curved portions 28c and 28d are far apart from the front surface of the housing 13. The housing 43 is then supported by the support member 28 so as not to tip over, by the straight portion 28b contacting the mounting surface 90 on which the fan 10D is placed. The fan 10D is placed on the mounting surface 90 with the battery 17 side facing the mounting surface 90. The arrow 9B shown in Figure 21 indicates the direction in which the air flows when the blade portion 14 rotates.

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

[0123] When the fan 10D, having the above configuration, is attached to the mounting hole 4 of the garment 2, first, the front portion 430ba of the cylindrical portion 430b of the front portion 430 of the housing 43 is inserted into the mounting hole 4 from the inside 510 of the garment 2. At this time, the flange portion 430c of the front portion 430 does not pass through the mounting hole 4, but instead contacts the inside 510 surface of the peripheral edge 5 of the mounting hole 4 of the garment 2. Also, the second portion 433b of the cover portion 433, which covers the battery 17, does not pass through the mounting hole 4, but is located inside 510 of the garment 2. Therefore, the battery 17 is located 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 contacts the outer surface 500 of the peripheral edge 5 of the garment 2. Specifically, the fixing member 21 is attached to the front portion 430 so that the flange portion 211 contacts the outer surface 500 of the peripheral edge 5, and the female threaded portion 210a of the fixing member 21 is screwed into the male threaded portion 430baa of the front portion 430ba of the cylindrical portion 430b. Then, the fixing member 21 is tightened clockwise when viewed from the outside 500 of the garment 2, so that the flange portion 211 of the fixing member 21 and the flange portion 430c of the front portion 430 grip the peripheral edge 5 of the garment 2. This fixes the fan 10D to the garment 2. When the blade portion 14 of the fan 10D fixed to the garment 2 rotates, air from the outside 500 of the garment 2 is drawn into the inside 510 of the garment 2 through the intake port 430aa and the exhaust port 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 portion 430. Then, the front portion 430ba of the cylindrical portion 430b of the front portion 430 is removed from the mounting hole 4.

[0126] Thus, in this example, similar to the first structural example, since the battery 17 is located inside the housing 43, the wiring extending from the battery 17 can be shortened. Therefore, the possibility of damage to the wiring can be reduced. As a result, the possibility of malfunction of the fan 10D can be reduced.

[0127] Furthermore, in this example, since a cable is not required to connect the battery and the fan unit, it becomes easier to attach the fan 10D to clothing 2.

[0128] Furthermore, in this example, since the operating unit 163 can be operated from the outside 500 of the garment 2, it becomes easier for the user to operate the operating unit 163.

[0129] Furthermore, in this example, since the display on the display unit 162 is visible from the outside 500 of the garment 2, the user can easily check the display on the display unit 162.

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

[0131] In this example, the housing 43 is attached to the garment 2 from the inside 510, and the fixing member 21 is attached to the housing 43 from the outside 500. Therefore, the user can attach the fixing member 21 to the housing 43 from the outside of the garment 2. Thus, the user can easily 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 inside the garment 2 at 510, the possibility of damage to the battery 17 can be reduced.

[0133] Furthermore, in this example, when the fan 10D is viewed from the intake side, the operating section 163 is located inside the outer shape of the flange section 211 surrounding the intake section 430a, as shown in Figure 17. This makes it possible to reduce the size of the fan 10D when viewed from the intake side.

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

[0135] Furthermore, in this example, when the fan 10D is viewed from the intake side, the display unit 162 is located inside the outer shape of the flange portion 211, as shown in Figure 17. This makes it possible to reduce the size of the fan 10D when viewed from the intake side.

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

[0137] Furthermore, in this example, when the fan 10D is viewed from the intake side, the battery 17, which is covered by the cover portion 433, is located outside the intake portion 430a. This reduces the possibility that the battery 17 may obstruct the intake of the fan 10D. Therefore, the performance of the fan 10D is improved.

[0138] <Fifth structural example> Figures 23-27 show an example of the structure of fan 10 (sometimes called fan 10E) in this example. Figures 23 and 24 show fan 10E viewed from the front. Figures 25 and 26 show fan 10D viewed from the rear. Figure 27 shows the internal structure of fan 10D. Figure 27 shows fan 10D attached to clothing 2.

[0139] As shown in Figures 23-27, the fan 10D comprises a housing 53 and the aforementioned fan blades 14, motor 15, circuit board 16, and battery 17. The fan blades 14, motor 15, circuit board 16, and battery 17 are housed in the housing 53.

[0140] The housing 53 includes a retaining portion 531 for holding the fan blades 14, motor 15, circuit board 16, and battery 17, and a fixing portion 530 for fixing the retaining portion 531 to the clothing 2. The fixing portion 530 is detachable from the retaining portion 531. The retaining portion 531 includes a front portion 5310 and a rear portion 5320. The rear portion 5320 functions as a cover portion that covers the rear surface of the fan blades 14. The rear portion 5320 is detachable from the front portion 5310. Figures 24 and 26 show the fan 10D with the fixing portion 530 and the rear portion 5320 removed. Hereafter, the rear portion 5320 may be referred to as the cover portion 5320.

[0141] The outer shape of the fixing part 530 is approximately circular when viewed from the front. The fixing part 530 comprises a front part 530a, a cylindrical part 530b, and a flange part 530c. An opening 530ab is provided in the center of the front part 530a. Multiple air intake ports 530aa are provided in the part of the front part 530a other than the opening 530ab. The front part 530a can be said to be an air intake section that takes in air from outside the housing 53 into the housing 53. Hereafter, the front part 530a may be referred to as the air intake section 530a.

[0142] The cylindrical portion 530b surrounds the periphery of the front portion 530a and is provided on the periphery so as to protrude backward from the periphery. A female threaded portion 530bb is formed on the inner circumferential surface of the cylindrical portion 530b, which is screwed into the male threaded portion 5313aa of the retaining portion 531, as described later. The flange portion 530c is provided on the outer circumferential surface of the rear portion of the cylindrical portion 530b so as to surround the cylindrical portion 530b. The flange portion 530c protrudes radially from the outer circumferential surface of the cylindrical portion 530b.

[0143] The outer shape of the cover portion 5320 of the holding portion 531 is approximately circular when viewed from the rear. The cover portion 5320 comprises a rear portion 5321 that covers the rear surface of the blade portion 14 and a cylindrical portion 5322. The cylindrical portion 5322 is provided on the periphery of the rear portion 5321, surrounding the periphery and protruding forward from the periphery. Multiple exhaust ports 5323 are formed in the rear portion 5321 and the cylindrical portion 5322. The multiple exhaust ports 5323 are formed avoiding the central part of the rear portion 5321. A male screw portion 5322a is formed on the outer circumferential surface of the cylindrical portion 5322, which screws into the female screw portion 5313bb ​​of the front portion 5310, described later.

[0144] The front portion 5310 of the holding portion 531 includes a fixed portion 5311 to which the motor 15, circuit board 16, and battery 17 are fixed. The front of the fixed portion 5311 is open. The front portion 5310 includes a cover portion 5312 that covers the front opening of the fixed portion 5311. Furthermore, the front portion 5310 includes an intermediate cylindrical portion 5313 located between the cylindrical portion 530b of the fixing portion 530 and the cylindrical portion 5322 of the cover portion 5320, and a flange portion 5314. The cover portion 5312, the intermediate cylindrical portion 5313, and the flange portion 5314 are integrally molded.

[0145] The intermediate cylindrical portion 5313 comprises a cylindrical front portion 5313a connected to the cylindrical portion 530b of the fixing portion 530, and a cylindrical rear portion 5313b connected to the cylindrical portion 5322 of the cover portion 5320. The front portion 5313a constitutes approximately one-third of the front of the intermediate cylindrical portion 5313. The rear portion 5313b constitutes approximately two-thirds of the rear of the intermediate cylindrical portion 5313. In the rear portion 5313b, there is a gap in the lower part, and the rear portion 5313b is not a perfect cylinder. The front cylindrical portion 530b, the rear cylindrical portion 5322, the intermediate cylindrical portion 5313 between them, and the third portion 5311c of the fixed portion 5311, described later, constitute the cylindrical peripheral wall portion (in other words, the side portion) 535 of the entire housing 53. The housing space 536, surrounded by the peripheral wall portion 535, houses the blade portion 14, the motor 15, and the circuit board 16. The outer circumferential surface of the front portion 5313a of the intermediate cylindrical portion 5313 has a male threaded portion 5313aa that screws into the female threaded portion 530bb of the fixing portion 530. The inner circumferential surface of the rear portion 5313b has a female threaded portion 5313bb ​​that screws into the male threaded portion 5322a of the cover portion 5320.

[0146] The flange portion 5314 is provided on the outer circumferential surface of the front portion of the rear portion 5313b, so as to surround the outer circumferential surface of the rear portion 5313b of the intermediate cylindrical portion 5313. The flange portion 5314 protrudes radially from the outer circumferential surface of the intermediate cylindrical portion 5313.

[0147] The fixed portion 5311 comprises a first portion 5311a to which the motor 15 and circuit board 16 are fixed, a second portion 5311b to which the battery 17 is fixed, and a third portion 5311c which constitutes a part of the lower portion of the peripheral wall portion 535. The third portion 5311c is located in the gap below the rear portion 5313b of the intermediate cylindrical portion 5313 and is connected to the rear portion 5313b so as to fill the gap. On the inner surface of the third portion 5311c (in other words, the surface on the side of the housing space 536), a female threaded portion 5311cc is formed which screws into the male threaded portion 5322a of the cover portion 5320. The male threaded portion 5322a of the cover portion 5320 screws into the female threaded portion 5311cc of the third portion 5311c and the female threaded portion 5313bb ​​of the rear portion 5313b of the intermediate cylindrical portion 5313.

[0148] The first part 5311a is located within the housing space 536. The first part 5311a extends downward from the center of the housing space 536, which is surrounded by the peripheral wall 535, when viewed from the front or rear, and reaches the third part 5311c, which is part of the peripheral wall 535. The first part 5311a includes a motor holder 5311aa that protrudes to the rear and holds the motor 15. The connecting portion 141 of the blade portion 14 covers the motor holder 5311aa. The rotation shaft 150 of the motor 15 extends to the outside of the motor holder 5311aa and is connected to the connecting portion 141 of the blade portion 14. The second part 5311b is connected to the third part 5311c and is located below the peripheral wall 535. The second part 5311b is curved to the rear according to the shape of the battery 17.

[0149] The cover portion 5312 comprises a first portion 5312a that closes the front opening of the first portion 5311a of the fixed portion 5311, and a second portion 5312b that closes the front opening of the second portion 5311b of the fixed portion 5311. The first portion 5312a extends downward from the center when the housing space 536 is viewed from the front or rear, and reaches the intermediate cylindrical portion 5313. The first portion 5312a has an opening-facing portion 5312aa that faces the opening 530ab of the fixing portion 530. The second portion 5312b is connected to the intermediate cylindrical portion 5313 and is located below the intermediate cylindrical portion 5313. The upper end of the second portion 5312b constitutes part of the flange portion 5314.

[0150] As shown in Figures 23 and 24, the light-emitting parts 162aa, 162ab, 162ac, 162ad, 162ae, and 162af of the display unit 162 of the circuit board 16 are exposed from the front surface of the opening-facing portion 5312aa of the first portion 5312a of the cover unit 5312. In addition, the operation buttons 163a of the operation unit 163 of the circuit board 16 are exposed from the front surface of the opening-facing portion 5312aa.

[0151] When the fan 10E, having the above configuration, is attached to the attachment hole 4 of the garment 2, first, the rear portion 5320 is attached to the front portion 5310 such that the male threaded portion 5322a of the cylindrical portion 5322 of the rear portion 5320 (in other words, the cover portion 5320) is screwed into the female threaded portion 5313bb ​​of the rear portion 5313b of the intermediate cylindrical portion 5313 of the front portion 5310. Then, the rear portion 5320 is fixed to the front portion 5310 by tightening it clockwise when viewed from the rear. This prepares the retaining portion 531.

[0152] Next, the front portion 5313a of the intermediate cylindrical portion 5313 of the retaining portion 531 is inserted into the mounting hole 4 from the inside 510 of the garment 2. At this time, the flange portion 5314 of the retaining portion 531 does not pass through the mounting hole 4, but instead contacts the inside 510 surface of the peripheral edge 5 of the mounting hole 4 of the garment 2. Also, the second portion 5312b of the cover portion 5312 that covers the battery 17 does not pass through the mounting hole 4, but is located inside 510 of the garment 2. Therefore, the battery 17 is located 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 such that the flange part 530c of the fixing part 530 contacts the outer surface 500 of the peripheral edge 5 of the garment 2. Specifically, the fixing part 530 is attached to the front part 531 of the holding part 531 such that the flange part 530c contacts the outer surface 500 of the peripheral edge 5, and the female threaded part 530bb of the fixing part 530 is screwed into the male threaded part 5313aa of the front part 5313a of the intermediate cylindrical part 5313 of the holding part 531. Then, the fixing part 530 is tightened clockwise when 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 grip the peripheral edge 5 of the garment 2. 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 drawn into the inside 510 of the garment 2 through the intake port 530aa and exhaust port 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 portion 5313a of the intermediate cylindrical part 5313 of the holding part 531 is removed from the mounting hole 4.

[0155] Thus, in this example, similar 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. Therefore, the possibility of damage to the wiring can be reduced. As a result, the possibility of malfunction of the fan 10E can be reduced.

[0156] Furthermore, in this example, since a cable is not required to connect the battery and the fan unit, it becomes easier to attach the fan 10E to the garment 2.

[0157] Furthermore, in this example, the operating section 163 is exposed from an area visible from the intake side of the housing 53. Specifically, the operating section 163 is visible from the front through the opening 530ab of the fixing section 530. Therefore, the operating section 163 can be operated from the outside 500 of the garment 2. This makes it easier for the user to operate the operating section 163.

[0158] Furthermore, 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 through the opening 530ab of the fixing part 530. Therefore, the display on 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 on the display unit 162.

[0159] Furthermore, in this example, when the fan 10E is viewed from the intake side, the operating section 163 is located inside the outer shape of the flange portion 530c of the housing 53, as shown in Figure 23. This makes it possible to reduce the size of the fan 10D when viewed from the intake side.

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

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

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

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

[0164] Furthermore, in this example, as shown in Figure 27, the operating unit 163 is located on the exhaust side (in other words, behind) the intake unit 530a. This allows for a larger total area of ​​the multiple intake ports 530aa provided by the intake unit 530a compared to the fan 10D described above. Therefore, the performance of the fan 10D is improved.

[0165] Furthermore, in this example, as shown in Figure 27, the display unit 162 is located on the exhaust side of the intake unit 530a. This allows for a larger total area of ​​the multiple intake ports 530aa provided by the intake unit 530a compared to the fan 10D described above. As a result, the performance of the fan 10D is improved.

[0166] In this example, the holding part 531, which holds the blade portion 14, is attached to the garment 2 from the inside 510. The fixing part 530 is attached to the holding part 531 from the outside 500 of the garment 2. Therefore, the user can attach the fixing part 530 to the holding part 531 from the outside of the garment 2. Thus, the user can easily 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 inside the garment 2 at 510, the possibility of damage to the battery 17 can be reduced.

[0168] Furthermore, in this example, when the fixing part 530 is attached to the holding part 531, it covers the front surface of the blade part 14. Therefore, by removing the fixing part 530 from the holding part 531, the front surface of the blade part 14 is no longer covered by the components constituting the housing 53. Thus, cleaning of the blade part 14 becomes easier.

[0169] Furthermore, in this example, the cover portion 5320 that covers the rear surface of the blade portion 14 is detachable. Therefore, by removing the cover portion 5320, the rear surface of the blade portion 14 is no longer covered by the components that make up the housing 53. Thus, cleaning of the blade portion 14 becomes easier.

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

[0171] <Sixth structural example> Figure 28 is a diagram showing an example of the internal structure of the fan 10 (sometimes called fan 10F) in this example. Figure 28 shows the fan 10F attached to clothing 2. As shown in Figure 28, the fan 10F comprises a main body 62, the aforementioned fixing member 11, a battery device 65, a mounting part 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 mounting part 66 and the retaining ring 67. The main body 62 comprises a housing 63, the aforementioned blades 14 and motor 15, and a connector 64 to which the cable 68 is connected. A lead wire 19 extending from the motor 15 is connected to the connector 64. Figure 29 is a perspective view showing an example of the structure of the main body 62 when viewed from the diagonal rear side. Figure 30 is a plan view showing an example of the structure of the housing 63 when viewed from the rear side. Figure 31 is a plan view showing an example of the structure of the battery device 65 and mounting part 66 when viewed from the front. Note that in Figure 28, the shape of the main body 62 is shown in a simplified form compared to Figures 29 and 30.

[0172] The front portion 630 comprises a front portion 630a, a cylindrical portion 630b, and a flange portion 630c. The front portion 630a is provided with multiple air intake ports 630aa, avoiding its central portion. The front portion 630a can also be considered an air intake section. The cylindrical portion 630b surrounds the periphery of the front portion 630a and is provided on the periphery so as to protrude backward from the periphery. A male threaded portion 630bb is formed on the outer circumferential surface of the cylindrical portion 630b, which screws into the female threaded portion 110a of the fixing member 11. The flange portion 630c is provided on the periphery of the front portion 630a so as to surround it. The flange portion 630c protrudes radially from the periphery of the front portion 630a. The front section 630a, when viewed from the front, is similar to the front section 330 of the fan 10C, when viewed from the front (see Figure 13).

[0173] The rear portion 631 comprises a rear surface portion 631a and a cylindrical portion 631b. The cylindrical portion 631b surrounds the periphery of the rear surface portion 631a and is provided on the periphery so as to protrude forward from the periphery. Multiple exhaust ports 631c are provided in the rear surface portion 631a and the cylindrical portion 631b. A first recess 631aa is provided in the center of the outer surface of the rear surface portion 631a. The 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 surface portion 631aa. The cylindrical connecting portion 141 of the blade portion 14 covers the protrusion 631ab. The rotation 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. Most of the connector 64 is located below the motor 15. A second recess 631ac is provided in the lower part of the connector 64 on the outer surface of the rear portion 631a. The second recess 631ac extends downward and reaches the periphery of the rear portion 631a.

[0175] Cable 68 is equipped with a connector 68a at one end. Connector 68a is detachable from connector 64 of main body 62. The connection port for connector 68a on connector 64 faces downward. Therefore, connector 68a of cable 68 is connected to connector 64 of main body 62 from below. The presence of a second recess 631ac on the underside of connector 64 makes it easier to connect connector 68a to connector 64 from below.

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

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

[0178] The battery device 65 comprises a housing 650 and the aforementioned circuit board 16 and battery 17 housed in the housing 650. The housing 650 is substantially rectangular. The housing 650 comprises 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 Figure 31, the light-emitting parts 162aa, 162ab, 162ac, 162ad, 162ae, and 162af of the display unit 162 of the circuit board 16 inside the housing 650 are exposed from the main surface 650a. In addition, the operation buttons 163a of the operation unit 163 of the circuit board 16 inside the housing 650 are exposed from the main surface 650a. The battery device 65 comprises a display unit 162 and an operation unit 163.

[0179] The end of cable 68 opposite to connector 68a is fixed inside housing 650. The end of cable 68 opposite to connector 68a is connected to control unit 161 on circuit board 16 inside housing 650. Cable 68 is routed out of housing 650 from the upper surface 650ca and connected to connector 64 on main body 62. Control signals for controlling motor 15, output by control unit 161, are supplied to motor 15 through cable 68, connector 64 on main body 62, and lead wires 19.

[0180] The mounting portion 66 is ring-shaped and has an opening 66a. The mounting portion 66 is connected to the upper surface 650ca of the side surface 650c of the housing 650. Specifically, the mounting portion 66 is connected to the end of the upper surface 650ca on the main surface 650b side. The mounting portion 66 is attached to the housing 650 such that the circular shape it forms 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 does not pass through the mounting hole 4, but instead comes into contact with the outer surface 500 of the peripheral edge 5 of the mounting hole 4 of the garment 2.

[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 contacts the inner surface 510 of the peripheral edge 5 of the garment 2. Specifically, the fixing member 11 is attached to the front portion 630 so that the flange portion 111 contacts the inner surface 510 of the peripheral edge 5, and the female thread portion 110a on the inner surface of the mounting portion 110 of the fixing member 11 is screwed into the male thread portion 630bb on the outer surface of the cylindrical portion 630b that protrudes from the inside 510 of the garment 2. Then, as the fixing member 11 is tightened clockwise when viewed from the inside 510 of the garment 2, the flange portion 630c of the front portion 630 and the flange portion 111 of the fixing member 11 clamp the peripheral edge 5 of the garment 2. This fixes the main body portion 62 to the garment 2.

[0183] Next, with the housing 650 of the battery device 65 facing downwards and the main surface 650a of the housing 650 facing backwards, the opening 66a of the mounting portion 66 is brought closer to the main body portion 62 from the inside 510 of the garment 2. As the opening 66a is brought closer to the main body portion 62, the mounting 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 does not pass through the opening 66a but hits the peripheral end of the mounting portion 66. Once the mounting 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 mounting portion 66 can also be called a suspension portion for suspending the battery device 65 from the main body portion 62.

[0184] Next, the retaining ring 67 is brought closer 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 is formed on the outer circumference of the mounting portion 110 of the fixing member 11 into which the retaining ring 67 fits. 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 circumference 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. In other words, 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 drawn into the inside 510 of the garment 2 through the intake port 630aa and the exhaust port 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 mounting part 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 removed from the mounting hole 4.

[0186] Thus, in this example, since the battery unit 65 is fixed to the main unit 62 so as to be located around the main unit 62, the cable 68 connecting the battery unit 65 and the main unit 62 can be shortened. Therefore, the possibility of damage to the cable 68 can be reduced. As a result, the possibility of malfunction of the fan 10F can be reduced.

[0187] Furthermore, shortening cable 68 makes it easier to attach fan 10F to garment 2.

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

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

[0190] <Example 7 of the structure> Figure 32 shows an example of the internal structure of the fan 10 (sometimes called fan 10G) in this example. Figure 32 shows the fan 10G attached to the garment 2. As shown in Figure 32, the fan 10G comprises the main body 62, fixing member 11, battery device 65, mounting part 66, and cable 68. However, the opening 66a of the mounting part 66 of the fan 10G is slightly smaller than the opening 66a of the mounting part 66 of the fan 10F. Also, the mounting part 66 of the fan 10G extends slightly straight upward from the upper surface 650ca of the housing 650, then inclined toward the main surface 650b, and then extends straight upward. The fan 10G does not have the retaining ring 67 described above.

[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 does not pass through the mounting hole 4, but instead hits the outer surface 500 of the peripheral edge 5 of the mounting hole 4 of the garment 2.

[0192] Next, with the main surface 650a of the housing 650 of the battery device 65 facing backward, the opening 66a of the mounting portion 66 is brought closer 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 edge of the mounting portion 66 contacts the inner surface of the peripheral edge 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 such that the flange portion 111 of the fixing member 11 contacts the peripheral edge of the mounting portion 66. Specifically, the fixing member 11 is attached to the front portion 630 such that the flange portion 111 contacts the peripheral edge of the mounting portion 66, and the female thread portion 110a on the inner surface of the mounting portion 110 of the fixing member 11 is screwed into the male thread portion 630bb on the outer surface of the cylindrical portion 630b that protrudes to the inside 510 of the garment 2. Then, as the fixing member 11 is tightened clockwise when viewed from the inside 510 of the garment 2, the flange portion 630c of the front portion 630 and the flange portion 111 of the fixing member 11 clamp the peripheral edge of the mounting portion 66 and the peripheral edge 5 of the garment 2. This fixes the battery device 65 to the main body 62. Finally, when the connector 68a of the cable 68 is connected to the connector 64 of the main unit 62, the attachment of the fan 10G to the garment 2 is complete.

[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 mounting part 66 is removed from the fixing member 11. Finally, the housing 63 is removed from the mounting hole 4.

[0195] Thus, in this example, since the battery unit 65 is fixed to the main unit 62 so as to be located around the main unit 62, the cable 68 connecting the battery unit 65 and the main unit 62 can be shortened. Therefore, the possibility of damage to the cable 68 can be reduced. As a result, the possibility of malfunction of the fan 10G can be reduced.

[0196] Furthermore, shortening cable 68 makes it easier to attach fan 10G to garment 2.

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

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

[0199] Furthermore, in this example, the retaining ring 67 is unnecessary, thus simplifying the configuration of fan 10G.

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

[0201] <Example 8 of the structure> Figure 33 shows an example of the internal structure of the fan 10 (sometimes called fan 10H) in this example. Figure 33 shows the fan 10H attached to the garment 2. Figure 34 shows the fan 10H viewed from the rear.

[0202] As shown in Figures 33 and 34, the fan 10H comprises the main body 62 and cable 68 described above. However, the second recess 631ac is not provided on the outer surface of the rear portion 631a of the rear part 631 of the housing 63 of the main body 62. Also, the main body 62 does not have a connector 64. Also, the cable 68 does not have a 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 rear portion 631a of the rear part 631 of the housing 63. A lead wire 19 extending from the motor 15 is connected to this end.

[0203] In addition to the main body 62 and cable 68, the fan 10H includes the aforementioned fixing member 11 and battery device 65, and a mounting portion 76 for attaching the battery device 65 to the main body 62. The mounting 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 housing 650 of the main body 62 and 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 mounting portion 76 is rotatable around the direction perpendicular to the longitudinal direction of the connecting portion 760 and the front-to-back direction of the fan 10H (left-to-right direction in Figure 34), starting from the end 760a of each connecting portion 760. The mounting portion 76 and the battery device 65 to which it is connected rotate together as a single unit. By rotating, the battery device 65 can take on two states, as shown in Figure 33: a first state in which it is located below the main body portion 62, and a second state in which it is located behind the main body portion 62.

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

[0205] When the fan 10H, which has the above configuration, is attached to the attachment hole 4 of the garment 2, first the battery device 65 suspended from the main body 62 is lifted, 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 mounting portion 75 connected thereto, and the housing 63 of the main body portion 62 are 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 does not pass through the mounting hole 4, but instead comes into contact with the outer surface 500 of the peripheral edge 5 of the mounting hole 4 of the garment 2.

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

[0208] Thus, in this example, since the battery unit 65 is mounted on the main unit 62 so as to be positioned around the main unit 62, the cable 68 connecting the battery unit 65 and the main unit 62 can be shortened. Therefore, the possibility of damage to the cable 68 can be reduced. As a result, the possibility of malfunction of the fan 10H can be reduced.

[0209] Furthermore, shortening cable 68 makes it easier to attach fan 10H to garment 2.

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

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

[0212] Furthermore, in this example, when attaching the fan 10H to the garment 2, it is not necessary to connect the cable 68 to the main unit 62, making it easier to attach the fan 10H to the garment 2. Also, when removing the fan 10H from the garment 2, it is not necessary to disconnect the cable 68 from the main unit 62, making it easier to remove the fan 10H from the garment 2.

[0213] <Example 9 of the structure> Figure 35 shows an example of the internal structure of the fan 10 (sometimes called fan 10I) in this example. Figure 35 shows the fan 10I attached to the garment 2. As shown in Figure 35, the fan 10I comprises a main body 72, a battery device 65, and a holding part 74 for holding the battery device 65. The main body 72 comprises a housing 73 and the aforementioned 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 comprises a front portion 330 (in other words, a fixing portion 330) provided by the fan 10C described above, a rear portion 731, and a cover portion 732. The blade portion 14 and the motor 15 are fixed to the rear portion 731. The rear portion 731 can be said to be 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, which holds the blade portion 14, etc., to the clothing 2. Hereafter, the rear portion 731 may be referred to as the holding portion 731.

[0215] The outer shape of the retaining portion 731 is approximately circular when viewed from the rear. The retaining portion 731 comprises a rear portion 731a, a cylindrical portion 731b, and a flange portion 731c. The cylindrical portion 731b surrounds the periphery of the rear portion 731a and is provided on the periphery so as to protrude forward from that periphery. Multiple exhaust ports 731d are provided on the rear portion 731a and the cylindrical portion 731b. A female threaded portion 731bb is formed on the inner circumferential surface of the cylindrical portion 731b, which screws into the male threaded portion 330bb of the fixing portion 330. The cylindrical portion 330b of the fixing portion 330 and the cylindrical portion 731b of the retaining portion 731 are connected to each other by the screwing of the male threaded portion 330bb and the female threaded portion 731bb, forming the cylindrical peripheral wall portion (in other words, the side portion) 735 of the entire housing 73. As the blade section 14 rotates, air is drawn into the housing 73 from the intake port 330aa, and the air drawn into the housing 73 is exhausted to the outside of the housing 73 from the exhaust port 731d.

[0216] The flange portion 731c is provided on the outer circumferential surface of the cylindrical portion 731b so as to surround it. The flange portion 731c protrudes radially from the outer circumferential surface of the cylindrical portion 731b. The flange portion 731c is located slightly behind the front end of the cylindrical portion 731b. Therefore, the flange portion 731c is not provided at the front end 731ba of the cylindrical portion 731b.

[0217] A recess 731aa is provided in the center of the outer surface of the back surface 731a of the holding portion 731. The motor 15 is fixed to the recess 731aa. A protrusion 731ab corresponding to the recess 731aa is provided on the inner surface of the back surface 731a. The cylindrical connecting portion 141 of the blade portion 14 covers the protrusion 731ab. The rotation shaft 150 of the motor 15 inside 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 back portion 731a of the holding portion 731 so as to close the recess 731aa of the back portion 731a. As a result, the motor 15 inside the recess 731aa is covered by the cover portion 732.

[0219] The retaining portion 74 that holds the battery device 65 is integrally molded with the housing 73. The retaining portion 74 functions as a fixing portion that secures the battery device 65 to the housing 73. The retaining portion 74 comprises a first portion 741 that covers the upper surface 650ca of the housing 650 of the battery device 65, a second portion 742 that covers the rear main surface 650a of the housing 650, and a third portion 743 that covers the front main surface 650b of the housing 650. The first portion 741 is connected to the lower portion of the cylindrical portion 731b of the retaining portion 731. The second portion 742 extends downward from the first portion 741 to the curved lower surface 650cb of the side surface 650c of the housing 650, and covers a portion of the lower surface 650cb. Similarly, the third portion 743 extends downward from the first portion 741 to the lower surface 650cb, and covers a portion of the lower surface 650cb. The second part 742 is provided with an opening. The light-emitting parts 162aa, 162ab, 162ac, 162ad, 162ae, 162af and the operation button 163a, which are exposed from the main surface 650a of the housing 650, are visible from the inside 510 of the garment 2 through the opening in the second part 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, which is held by the retaining part 74. From the upper surface 650ca, it enters the housing 650 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 cylindrical portion 731b of the retaining 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 retaining portion 731 does not pass through the mounting hole 4, but instead contacts the inner surface 510 of the peripheral edge 5 of the mounting hole 4 of the garment 2. Also, the retaining portion 74 does not pass through the mounting hole 4, but is located on the inside 510 of the garment 2.

[0222] Next, the fixing part 330 is attached to the retaining part 731 from the outside 500 of the garment 2 such that the flange portion 330c of the fixing part 330 contacts the outer surface 500 of the peripheral edge 5 of the garment 2. Specifically, the fixing part 330 is attached to the retaining part 731 such that the flange portion 330c contacts the outer surface 500 of the peripheral edge 5, and the male threaded portion 330bb of the cylindrical portion 330 of the fixing part 330 is screwed into the female threaded portion 731bb of the cylindrical portion 731b of the retaining part 731. Then, as the fixing part 330 is tightened clockwise when viewed from the outside 500 of the garment 2, the flange portion 330c of the fixing part 330 and the flange portion 731c of the retaining part 731 grip the peripheral edge 5 of the garment 2. This fixes the fan 10I 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 drawn into the inside 510 of the garment 2 through the intake port 330aa and the exhaust port 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 removed from the mounting hole 4.

[0224] Thus, in this example, since the battery device 65 is fixed to the main body 72 so as to be located around the housing 73, the wiring (lead wire 19 in this example) connecting the battery device 65 and the main body 72 can be shortened. Therefore, the possibility of damage to the wiring can be reduced. As a result, the possibility of malfunction of the fan 10I can be reduced.

[0225] Furthermore, in this example, since a cable is not required to connect the battery unit 65 and the main unit 72, the fan 10I can be easily attached to the garment 2.

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

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

[0228] The above description mentioned various structural examples of fan 10. Below, we will describe various operating examples of fan 10. The operating examples of fan 10 described below can be applied to each of the fans 10A to 10I mentioned above.

[0229] <Example of operation 1> The fan 10 in this example is capable of wireless communication with other devices. Figure 36 shows an example of the configuration of the circuit board 16 (sometimes called circuit board 16A) in this example. As shown in Figure 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 devices 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 powered off or powered on. The antenna 165a may be provided on a part other than the board 160. For example, the antenna 165a may be provided on the housing of the fan 10. Hereafter, devices that the wireless communication unit 165 can communicate with may be referred to as external devices.

[0230] The wireless communication unit 165 is capable of wirelessly communicating with an external device in accordance with at least one type of wireless communication standard. The wireless communication standards that the wireless communication unit 165 conforms to include, for example, short-range wireless communication standards. For example, the wireless communication standards that the wireless communication unit 165 conforms to may include Bluetooth®, ZigBee®, or NFC (Near Field Communication). Furthermore, the wireless communication standards that the wireless communication unit 165 conforms to may include standards that support wireless LAN (Local Area Network), such as WiFi. Furthermore, the wireless communication standards that the wireless communication unit 165 conforms to may include standards that support LPWA (Low Power Wide Area Network). For example, the wireless communication standards that the wireless communication unit 165 conforms to may include SIGFOX, LoRaWAN, or NB-IoT. Below, the operation of the fan 10 will be described using the case where the wireless communication unit 165 communicates with an external device in accordance with Bluetooth as an example.

[0231] Various devices are included in the external devices that fan 10 can wirelessly communicate with. Examples of external devices that fan 10 can wirelessly communicate with include other fans 10, portable electronic devices, and electric machinery. Examples of portable electronic devices that fan 10A can wirelessly communicate with include mobile phones such as smartphones, tablet devices, notebook personal computers, and wearable devices. Wearable devices that fan 10A can wirelessly communicate with may be of the type worn on the arm, such as a wristband or watch, or of the type worn on the head, such as a headband or glasses, or of the type worn on the body, such as clothing.

[0232] As an example, the operation of each fan 10 when multiple fans 10 communicate wirelessly with each other in accordance with Bluetooth will be described. For example, multiple fans 10 attached to the same garment 2 are paired with each other. As a result, multiple fans 10 attached to the same garment 2 can communicate wirelessly with each other when each is powered on. Hereafter, unless otherwise specified, "multiple fans 10" refers to multiple paired fans 10. Also, one fan 10 of interest among the multiple fans 10 may be referred to as the target fan 10.

[0233] When the operation button 163a of the target fan 10 is briefly pressed while the fan is powered on, the control unit 161 of the target fan 10 changes the airflow of the fan 10A by controlling the rotation speed of the motor 15 and generates airflow information indicating the changed airflow. The wireless communication unit 165 transmits the airflow 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 airflow information for a fan 10 that is powered on, the control unit 161 controls the motor 15 to set the airflow of that fan 10 to the airflow indicated by the received airflow information. As a result, when the operation button 163a of one of the multiple fans 10 is briefly pressed, the airflow of all the fans 10 is set to the same level.

[0234] Furthermore, if the operation button 163a of the target fan 10 is pressed and held, the control unit 161 of the target fan 10 may generate a power-off signal instructing the other fans 10 to be turned off before turning off the target fan 10. In this case, before the target fan 10 is turned off, the wireless communication unit 165 of the target fan 10 transmits the power-off signal to the fans 10 other than the target fan 10. When the wireless communication unit 165 receives the power-off signal from the fan 10 that is turned on, the control unit 161 turns off the fan 10. As a result, when the operation button 163a of one of the fans 10 is pressed and held, all of the fans 10 are turned off.

[0235] Furthermore, if the operation button 163a of the target fan 10 is pressed and held, the control unit 161 of the target fan 10 may turn on the target fan 10 and generate a power-on signal instructing the other fans 10 to turn on as well. In this case, the wireless communication unit 165 of the target fan 10 transmits the power-on signal to the fans 10 other than the target fan 10 among the multiple fans 10. When the wireless communication unit 165 receives the power-on signal from the fan 10 that is in the power-off state, the control unit 161 turns on the fan 10. As a result, when the operation button 163a of one of the multiple fans 10 is pressed and held, all of the multiple fans 10 are turned on.

[0236] As another example, the operation of the fan 10 and the portable electronic device when the fan 10 communicates wirelessly with a portable electronic device such as a mobile phone will be described. Figure 37 is a diagram showing an example of the configuration of the portable electronic device 800. As shown in Figure 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 comprehensively manage the operation of the portable electronic device 800 by controlling 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 capabilities for performing various functions, as will be described in more detail below. The description above regarding the at least one processor in the control unit 161 of the fan 10 can also be applied to the at least one processor in the control unit 801. Note that all or some of the functions of the control unit 801 may be implemented by hardware circuits that do not require software to implement those functions.

[0238] The wireless communication unit 802 is capable of wirelessly communicating with devices outside the portable electronic device 800. The wireless communication unit 802 can also be called a wireless communication circuit. The wireless communication unit 802 is capable of wirelessly communicating with external devices in accordance with at least one type of wireless communication standard. The wireless communication standards that the wireless communication unit 802 conforms to include, for example, short-range wireless communication standards. For example, the wireless communication standards that the wireless communication unit 802 conforms to may include Bluetooth, ZigBee, or NFC. Furthermore, the wireless communication standards that the wireless communication unit 802 conforms to may include standards that support wireless LAN. Furthermore, the wireless communication standards that the wireless communication unit 802 conforms to may include standards that support LPWA. For example, the wireless communication standards that the wireless communication unit 802 conforms to 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 and is capable of displaying various types of information such as characters, symbols, and graphics on the display surface 803a.

[0240] The touch panel 804 is capable of detecting operations performed on the display surface 803a by an operator such as a finger. 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 can input an electrical signal corresponding to that operation to the control unit 801. Based on the electrical signal from the touch panel 804, the control unit 801 can identify the content of the operation performed on the display surface 803a. The control unit 801 can then perform processing according to the identified content of the operation.

[0241] Sensor 805 may include, for example, an accelerometer. Sensor 805 may also include sensors other than an accelerometer. For example, sensor 805 may include at least one of the following sensors: a proximity sensor, a gyroscope, a fingerprint sensor, a temperature sensor, a barometric pressure sensor, a position detection sensor, and a geomagnetic sensor.

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

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

[0244] For example, when the control unit 801 of the portable electronic device 800 detects a predetermined operation on the display surface 803a via the touch panel 804, it displays a screen 810 on the display unit 803 to turn on the fan 10. Figure 38 shows an example of a screen 810 displayed on the display surface 803a.

[0245] As shown in Figure 38, the screen 810 displays a first operation button 811 and a second operation button 812. When the touch panel 804 detects an operation on the first operation button 811, the control unit 801 generates a power-on signal instructing the fan 10 to be powered 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 a power-on signal, the wireless communication unit 802 transmits the generated power-on signal to the fan 10. In the case of the fan 10 being powered off, when the wireless communication unit 165 receives the power-on signal, the control unit 161 powers the fan 10 on.

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

[0247] Furthermore, when the control unit 801 of the portable electronic device 800 detects a predetermined operation on the display surface 803a via the touch panel 804, it may display a screen 820 on the display unit 803 to turn off the fan 10. Figure 39 shows an example of a screen 820 displayed on the display surface 803a.

[0248] As shown in Figure 39, the screen 820 displays a first operation button 821 and a second operation button 822. When the touch panel 804 detects an operation on the first operation button 821, the control unit 801 generates a power-off signal instructing the fan 10 to be powered 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 a power-off signal, the wireless communication unit 802 transmits the generated power-off signal to the fan 10. In the case of the fan 10 being powered on, when the wireless communication unit 165 receives the power-off signal, the control unit 161 powers off the fan 10.

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

[0250] Furthermore, the portable electronic device 800 may set the airflow of the fan 10 by communicating wirelessly with the fan 10. For example, when the touch panel 804 detects a predetermined operation on the display surface 803a, the control unit 801 displays a screen 830 for setting the airflow of the fan 10 on the display unit 803. Figure 40 shows an example of a screen 830 displayed on the display surface 803a.

[0251] As shown in Figure 40, the screen 830 displays a first operation button 831, a second operation button 832, and a third operation button 833. When the touch panel 804 detects an operation on the first operation button 831, the control unit 801 generates a first airflow signal instructing the fan 10 to set the airflow to "high". The first airflow signal generated by the control unit 801 is transmitted to the fan 10 from the wireless communication unit 802. When the touch panel 804 detects an operation on the second operation button 832, the control unit 801 generates a second airflow signal instructing the fan 10 to set the airflow to "medium". The second airflow signal generated by the control unit 801 is transmitted to the fan 10 from the wireless communication unit 802. Then, when the touch panel 804 detects an operation on the third operation button 833, the control unit 801 generates a third airflow signal instructing the fan 10 to set the airflow to "low". The third airflow signal generated by the control unit 801 is transmitted from the wireless communication unit 802 to the fan 10.

[0252] When the fan 10 is powered on, if the wireless communication unit 165 receives a first airflow signal, the control unit 161 controls the motor 15 to set the airflow of the fan 10 to "high". When the wireless communication unit 165 receives a second airflow signal, the control unit 161 controls the motor 15 to set the airflow of the fan 10 to "medium". Then, when the wireless communication unit 165 receives a third airflow signal, the control unit 161 controls the motor 15 to set the airflow of the fan 10 to "low".

[0253] In this way, the user of the portable electronic device 800 can set the airflow 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, if the fan 10 is powered on, the control unit 161 generates fan information. Then, the wireless communication unit 165 transmits the fan information to the portable electronic device 800. When the wireless communication unit 802 of the portable electronic device 800 receives the fan information, the control unit 801 displays the received fan information, for example, on the display unit 803.

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

[0256] Figure 41 shows 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 screen 840 displays fan information. Specifically, the screen 840 displays first information 841 indicating the remaining battery level 17, second information 842 indicating the continuous operating time, and third information 843 indicating the remaining operating time.

[0257] Note that the fan information may include other information. For example, the fan information may include the current airflow of fan 10.

[0258] As another example, the operation of the fan 10 and the electric machine when the fan 10 performs electromechanical and wireless communication will be described. FIG. 42 is a diagram showing an example of the electrical configuration of the electric machine 850. The electric machine 850 is, for example, an electric machine that generates a large amount of dust when it is in use. For example, the electric machine 850 is an electric tool, a chainsaw, a hedge trimmer, or a brush cutter that generates a large amount of dust when it is in use. Electric tools that generate a large amount of dust when they are in use include, for example, disk grinders, circular saws, and steel cutters.

[0259] As shown in FIG. 42, the electric machine 850 includes a control unit 851, a wireless communication unit 852, and a motor 853. The motor 853 operates the movable part of the electric machine 850. The movable part of the electric machine 850 is, for example, a grindstone, a chip saw, or a blade.

[0260] The control unit 851 can comprehensively manage the operation of the electric machine 850 by controlling other components of the electric machine 850. The control unit 851 can also be said to be a control circuit. The control unit 851 includes at least one processor in order to provide control and processing capabilities for executing various functions, as will be 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 part of the functions of the control unit 851 may be realized by a hardware circuit that does not require software for realizing the functions.

[0261] The wireless communication unit 852 can wirelessly communicate with a device outside the electromechanical device 8500. The wireless communication unit 852 can also be said to be a wireless communication circuit. The wireless communication unit 852 can wirelessly communicate with an external device in accordance with at least one type of wireless communication standard. The wireless communication standards complied with by the wireless communication unit 852 include, for example, short-range wireless communication standards. For example, the wireless communication standards complied with by the wireless communication unit 802 may include Bluetooth, may include ZigBee, or may include NFC. Also, the wireless communication standards complied with by the wireless communication unit 852 may include standards corresponding to wireless LAN. Also, the wireless communication standards complied with by the wireless communication unit 852 may include standards corresponding to LPWA. For example, the wireless communication standards complied with by the wireless communication unit 852 may include SIGFOX, may include LoRaWAN, or may include NB-IoT.

[0262] When the fan 10 and the electromechanical device 850 are paired, the fan 10 and the electromechanical device 850 can wirelessly communicate with each other in accordance with Bluetooth. The fan 10 capable of wirelessly communicating with the electromechanical device 850 may receive operation information regarding the operation of the electromechanical device 850 from the electromechanical device 850 and control the motor 15 based on the received operation information.

[0263] For example, consider a case where an operator using the electromechanical device 850 works while wearing the fan-equipped clothing 1. In this case, the electromechanical device 850 and each fan 10 included in the fan-equipped clothing 1 are paired. Thereby, the electromechanical device 850 used by the operator and each fan 10 of the fan-equipped clothing 1 worn by the operator can wirelessly communicate with each other in accordance with Bluetooth.

[0264] When the operation of the electromechanical device 850 starts, that is, when the rotation of the motor 853 starts, the control unit 851 of the electromechanical device 850 capable of wirelessly communicating with each fan 10 of the fan-equipped clothing 1 generates operation start information as operation information. The operation start information is information indicating that the operation of the electromechanical device 850 has started. The wireless communication unit 852 transmits the operation start information generated by the control unit 851 to the fan 10.

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

[0266] In a fan 10 paired with an electric motor 850 and powered on, 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 fan blades 14. Subsequently, when the wireless communication unit 802 receives operation end information, the control unit 801 starts the motor 15 and rotates the fan blades 14. At this time, the control unit 801 may start 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, a few minutes.

[0267] In this way, by stopping the rotation of the motor 15 when the fan 10 receives operation start information, the fan blades 14 of the fan 10 will not rotate when the electric machine 850, which generates dust during use, is in operation. If the fan blades 14 of the fan 10 rotate when dust is being generated, the fan 10 may suck in the dust. If the fan 10 sucks in dust, the fan 10 may malfunction. In addition, dust may get inside the garment 2 510, causing discomfort to the worker wearing the garment 2. By preventing the fan blades 14 of the fan 10 from rotating when the electric machine 850 is in operation, the possibility of the fan 10 malfunctioning or dust getting inside the garment 2 510 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 completion information, the fan blades 14 of the fan 10 begin to rotate a predetermined time after the operation of the electric machine 850, which generates dust during use, has finished. Since dust may remain in the air for a while after the operation of the electric machine 850 has finished, if the fan blades 14 of the fan 10 were to rotate immediately after the operation of the electric machine 850 has finished, the fan 10 could potentially suck in the dust. In this example, if the fan blades 14 of the fan 10 begin to rotate a predetermined time after the operation of the electric machine 850 has finished, the possibility of the fan 10 sucking in dust can be reduced.

[0269] Note that the operation information transmitted by the electric motor 850 to the fan 10 is not limited to the example above.

[0270] <Second example of operation> The fan 10 in this example can control the motor 15 based on the detection results of the sensor. Figure 43 is a block diagram mainly showing the electrical configuration of the fan 10 in this example. As shown in Figure 43, the fan 10 in this example is equipped with a temperature sensor 900 that detects the temperature of the air taken in by the fan 10. The temperature sensor 900 is located, for example, near the air intake port provided in the 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 control unit 161 increases the rotation speed of the motor 15 as the temperature detected by the temperature sensor 900 increases. As a result, the airflow of the fan 10 increases as the temperature detected by the temperature sensor 900 increases. Hereafter, the temperature detected by the temperature sensor 900 may be referred to as the detected temperature.

[0272] The control unit 161 sets the rotation speed of the motor 15 to the first speed and the airflow of the fan 10 to "low" when the detected temperature is low. The control unit 161 determines that the detected temperature is low if, for example, the detected temperature is less than 15 degrees. The control unit 161 also sets the rotation speed of the motor 15 to the second speed and the airflow of the fan 10 to "medium" when the detected temperature is moderate. The control unit 161 determines that the detected temperature is moderate if, for example, the detected temperature is 15 degrees or more but less than 25 degrees. The control unit 161 then sets the rotation speed of the motor 15 to the third speed and the airflow of the fan 10 to "high" when the detected temperature is high. The control unit 161 determines that the detected temperature is high if, for example, the detected temperature is 25 degrees or more. The control unit 161 sets the airflow of the fan 10 based on the detected temperature each time a temperature is obtained from the temperature sensor 900.

[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 according to the temperature of the air taken in by the fan 10.

[0274] The fan 10 may also be equipped with a humidity sensor 901 that detects the humidity of the air it takes in, as shown in Figure 44. The humidity sensor 901, like the temperature sensor 900, is positioned, for example, near an air intake in the housing of the fan 10. The humidity sensor 901 repeatedly detects the humidity of the air taken in by the fan 10.

[0275] If the fan 10 is equipped with a humidity sensor 901, the control unit 161 may control the motor 15 based on the detection result of the humidity sensor 901. For example, the control unit 161 increases the rotation speed of the motor 15 as the humidity detected by the humidity sensor 901 increases. As a result, the airflow of the fan 10 increases as the humidity detected by the humidity sensor 901 increases. Hereafter, the humidity detected by the humidity sensor 901 may be referred to as the detected humidity.

[0276] The control unit 161 controls the rotation speed of the motor 15 to set the airflow of the fan 10 to "low" when the detected humidity is low. The control unit 161 determines that the detected humidity is low if, for example, the detected humidity is less than 85 degrees. The control unit 161 also controls the rotation speed of the motor 15 to set the airflow of the fan 10 to "medium" when the detected humidity is moderate. The control unit 161 determines that the detected humidity is moderate if, for example, the detected humidity is 85% or more but less than 90%. The control unit 161 then controls the rotation speed of the motor 15 to set the airflow of the fan 10 to "high" when the detected humidity is high. The control unit 161 determines that the detected humidity is high if, for example, the detected humidity is 90% or more. The control unit 161 sets the airflow of the fan 10 based on the detected humidity each time that a detected humidity is obtained from the humidity sensor 901.

[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] The fan 10 may include a temperature sensor 900 and a humidity sensor 901, as shown in Figure 45. In other words, the fan 10 may include a composite sensor consisting of a temperature sensor 900 and a humidity sensor 901. In this case, the control unit 161 repeatedly determines the discomfort index based on the temperature and humidity detected by the composite sensor, for example. Each time the discomfort index is determined, the control unit 161 controls the motor 15 based on the determined discomfort index. For example, if the discomfort index is low, the control unit 161 controls the rotation speed of the motor 15 to set the airflow of the fan 10 to "low". The control unit 161 determines that the discomfort index is low if it is, for example, less than 70. Also, if the discomfort index is moderate, the control unit 161 controls the rotation speed of the motor 15 to set the airflow of the fan 10 to "medium". The control unit 161 determines that the discomfort index is moderate if it is, for example, 70 or more but less than 80. Then, if the discomfort index is high, the control unit 161 controls the rotation speed of the motor 15 to set the airflow of the fan 10 to "high". The control unit 161 determines that the discomfort index is high if, for example, the discomfort index is 80 or higher.

[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] The fan 10 may be equipped with an acceleration sensor 902 for detecting the acceleration of the fan 10, as shown in Figure 46. The acceleration sensor 902 is, for example, a three-axis acceleration sensor. The acceleration sensor 902 may be provided on or off the substrate 160. If the fan 10 is equipped with an acceleration sensor 902, the control unit 161 may control the motor 15 based on the detection result of the acceleration sensor 902. Hereafter, the acceleration detected by the acceleration sensor 902 may be referred to as the detected acceleration.

[0281] The control unit 161 repeatedly determines the momentum 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 user's calorie expenditure per unit time may be used as the user's momentum per unit time. If the momentum per unit time is small, the control unit 161 controls the rotation speed of the motor 15 to set the airflow of the fan 10 to "low". If the momentum per unit time is moderate, the control unit 161 controls the rotation speed of the motor 15 to set the airflow of the fan 10 to "medium". If the momentum per unit time is large, the control unit 161 controls the rotation speed of the motor 15 to set the airflow of the fan 10 to "high". Each time the momentum per unit time is determined, the control unit 161 sets the airflow of the fan 10 based on the determined momentum.

[0282] In this way, the motor 15 of the fan 10 is controlled based on the detection results of the acceleration sensor 902, thereby ensuring proper control of the motor 15. Note that other information may be used as the user's momentum per unit time. For example, the user's number of steps per unit time may be used as the user's momentum per unit time.

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

[0284] When the fan 10 includes the 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. For example, when the detected dust concentration is equal to or higher than the threshold value, the control unit 161 determines that the detected dust concentration 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 concentration 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 about 1 minute to several minutes, for example. After the control unit 161 stops the rotation of the motor 15 for a predetermined time, step s2 is executed again. Thereafter, the control unit 161 operates in the same manner.

[0287] In step s1, if it is determined that the detected dust concentration is low, in step s3, the control unit 161 rotates the motor 15. If the motor 15 is stopped rotating when step s3 is executed, the control unit 161 starts the motor 15 rotating in step s3. On the other hand, if the motor 15 is rotating when step s3 is executed, the control unit 161 maintains the rotation of the motor 15 in step s3. 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 controlled based on the detection result of the dust sensor 903, thereby ensuring that the motor 15 is properly controlled. In step s1, the control unit 161 may also determine whether the detected dust concentration remains high for a predetermined period of time or longer.

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

Furthermore, the various examples described above can be combined and applied insofar as they do not contradict each other. And it is understood that countless examples not illustrated can be conceivable without falling outside the scope of this disclosure. [Explanation of Symbols]
