At this time, the control unit 801 may rotate the motor 15 after a predetermined time has elapsed after the wireless communication unit 802 receives the operation end information. The predetermined time is set to, for example, about several minutes.

In this way, when the fan 10 stops the rotation of the motor 15 when it receives the operation start information, the blade portion 14 of the fan 10 is operating when the electric machine 850 that generates dust during its use is operating. Will not rotate. If the blade portion 14 of the fan 10 rotates in a situation where dust is generated, the fan 10 may suck in the dust. If the fan 10 sucks in dust, the fan 10 may break down. In addition, dust may enter the inner 510 of the clothes 2 and the worker wearing the clothes 2 may feel uncomfortable. Since the blade portion 14 of the fan 10 does not rotate when the electric machine 850 is operating, it is possible to reduce the possibility that the fan 10 will break down or dust will enter the inner 510 of the clothes 2.

Further, after a predetermined time has elapsed since the fan 10 received the operation end information, the rotation of the motor 15 is stopped, so that a predetermined time is required after the operation of the electric machine 850, which generates dust during its use, is completed. Later, the blade portion 14 of the fan 10 will rotate. Since dust may exist in the air for a while after the operation of the electric machine 850 is completed, when the blade portion 14 of the fan 10 rotates immediately after the operation of the electric machine 850 is completed, the fan 10 is activated. May inhale dust. As in this example, when the blade portion 14 of the fan 10 starts to rotate after a predetermined time from the end of the operation of the electric machine 850, the possibility that the fan 10 sucks dust can be reduced. ..

The operation information transmitted by the electric machine 850 to the fan 10 is not limited to the above example.

<Second operation example>
The fan 10 according to this example can control the motor 15 based on the detection result of the sensor. FIG. 43 is a block diagram mainly showing the electrical configuration of the fan 10 according to this example. As shown in FIG. 43, the fan 10 according to this example includes a temperature sensor 900 that detects the temperature of the air taken in by the fan 10. The temperature sensor 900 is arranged, for example, near the 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.

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 higher the temperature detected by the temperature sensor 900, the larger the air volume of the fan 10. Hereinafter, the temperature detected by the temperature sensor 900 may be referred to as a detection temperature.

When the detection temperature is low, the control unit 161 sets the rotation speed of the motor 15 to the first speed and sets the air volume of the fan 10 to “small”. When the detection temperature is, for example, less than 15 degrees, the control unit 161 determines that the detection temperature is low. Further, when the detection temperature is medium, the control unit 161 sets the rotation speed of the motor 15 to the second speed and sets the air volume of the fan 10 to “medium”. When the detection temperature is, for example, 15 degrees or more and less than 25 degrees, the control unit 161 determines that the detection temperature is medium. Then, when the detection temperature is high, the control unit 161 sets the rotation speed of the motor 15 to the third speed and sets the air volume of the fan 10 to “large”. When the detection temperature is, for example, 25 degrees or higher, the control unit 161 determines that the detection temperature is high. The control unit 161 sets the air volume of the fan 10 based on the detected temperature each time the detected temperature is obtained by the temperature sensor 900.

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.

As shown in FIG. 44, the fan 10 may include a humidity sensor 901 that detects the humidity of the air taken in by the fan 10. Like the temperature sensor 900, the humidity sensor 901 is arranged near, for example, an intake port provided in the housing of the fan 10. The humidity sensor 901 repeatedly detects the humidity of the air taken in by the fan 10.

When the fan 10 includes the 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 higher the humidity detected by the humidity sensor 901, the larger the air volume of the fan 10. Hereinafter, the humidity detected by the humidity sensor 901 may be referred to as a detected humidity.

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

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.

The fan 10 may include a temperature sensor 900 and a humidity sensor 901, as shown in FIG. In other words, the fan 10 may include a composite sensor including a temperature sensor 900 and a humidity sensor 901. In this case, the control unit 161 repeatedly obtains the discomfort index based on, for example, the detected temperature and the detected humidity of the composite sensor. Then, each time the control unit 161 obtains the discomfort index, the control unit 161 controls the motor 15 based on the obtained discomfort index. For example, when the discomfort index is small, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "small". When the discomfort index is, for example, less than 70, the control unit 161 determines that the discomfort index is low. Further, when the discomfort index is medium, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "medium". When the discomfort index is, for example, 70 or more and less than 80, the control unit 161 determines that the discomfort index is medium. Then, when the discomfort index is high, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "large". When the discomfort index is, for example, 80 or more, the control unit 161 determines that the discomfort index is high.

In this way, the motor 15 of the fan 10 is controlled based on the detection result of the sensor that detects the temperature and humidity of the air taken in by the fan 10, so that the motor 15 can be driven according to the temperature and humidity of the air taken in by the fan 10. 15 is properly controlled.

As shown in FIG. 46, the fan 10 may include an acceleration sensor 902 that detects the acceleration of the fan 10. The acceleration sensor 902 is, for example, a 3-axis acceleration sensor. The acceleration sensor 902 may be provided on the substrate 160 or may be provided on the substrate 160. When the fan 10 includes the acceleration sensor 902, the control unit 161 may control the motor 15 based on the detection result of the acceleration sensor 902. Hereinafter, the acceleration detected by the acceleration sensor 902 may be referred to as a detected acceleration.

Based on the detected acceleration, the control unit 161 repeatedly obtains the amount of exercise per unit time of the user wearing the clothes 2 to which the fan 10 is attached. As the amount of exercise per unit time of the user, for example, the calorie consumption per unit time of the user is adopted. When the momentum per unit time is small, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "small". Further, when the momentum per unit time is medium, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "medium". Then, when the momentum per unit time is large, the control unit 161 controls the rotation speed of the motor 15 to set the air volume of the fan 10 to "large". Each time the control unit 161 obtains the momentum per unit time, the control unit 161 sets the air volume of the fan 10 based on the obtained momentum.

In this way, the motor 15 of the fan 10 is controlled based on the detection result of the acceleration sensor 902, so that the motor 15 is appropriately controlled. In addition, other information may be adopted as the amount of exercise per unit time of the user. For example, the number of steps per unit time of the user may be adopted as the amount of exercise per unit time of the user.

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

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.

As shown in FIG. 48, in step s1, the control unit 161 determines whether or not 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 active 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 active is low.

If it is determined in step s1 that the detected dust concentration is high, in step s2, the control unit 161 stops the rotation of the motor 15 for a predetermined time. The predetermined time is set to, for example, about 1 minute to several minutes. The control unit 161 stops the rotation of the motor 15 for a predetermined time, and then executes step s2 again. After that, the control unit 161 operates in the same manner.

If it is determined in step s1 that the detected dust concentration is low, the control unit 161 rotates the motor 15 in step s3. If the rotation of the motor 15 is stopped during the execution of step s3, the control unit 161 starts the rotation of the motor 15 in step s3. On the other hand, if the motor 15 is rotating during the execution of step s3, the control unit 161 maintains the rotation of the motor 15 in step s3. The control unit 161 executes step s2 again after step s3. After that, the control unit 161 operates in the same manner.

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

The fan 10 may include two or more of the temperature sensor 900, the humidity sensor 901, the acceleration sensor 902, and the dust sensor 903. In other words, the fan 10 may be a composite sensor including two or more of the temperature sensor 900, the humidity sensor 901, the acceleration sensor 902, and the dust sensor 903. Further, the fan 10 may include at least one of the temperature sensor 900, the humidity sensor 901, the acceleration sensor 902, and the dust sensor 903, and the above-mentioned wireless communication unit 852.
