  • 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.
  • 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.
  • the control unit 161 may control the motor 15 based on the detection result of the acceleration sensor 902.
  • the acceleration detected by the acceleration sensor 902 may be referred to as a detected acceleration.
  • the control unit 161 Based on the detected acceleration, the control unit 161 repeatedly obtains the momentum 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.
  • 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”.
  • the control unit 161 sets the air volume of the fan 10 based on the obtained momentum.
  • 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.
  • 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.
  • the fan 10 may include a dust sensor 903 that detects dust taken in by the fan 10.
  • 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.
  • the dust concentration output by the dust sensor 903 may be referred to as a detected dust concentration.
  • 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.
  • 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.
  • step s2 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.
  • step s1 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.
  • 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.
  • 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.
  • 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.
  • the garment 1 with a fan and the fan 10 have been described in detail, but the above description is an example in all aspects, and the disclosure is not limited thereto.
  • the various examples described above can be applied in combination as long as they do not contradict each other. And it is understood that innumerable examples not illustrated can be assumed without departing from the scope of this disclosure.
