  In the above configuration, as shown in FIG. 4, when the humidity detection value detected by the humidity sensor 7 is equal to or less than the first set value, the microcomputer 11 calculates that the operating air volume is strong and outputs it to the fan motor 5. If the humidity detection value detected by the humidity sensor 7 is greater than the first set value and less than or equal to the second set value, the microcomputer 11 calculates the operation air volume and outputs it to the fan motor 5. When the humidity detection value detected by the humidity sensor 7 is greater than the second set value and less than or equal to the third set value, the microcomputer 11 calculates that the operating air volume is weak and outputs it to the fan motor 5. When the humidity detection value detected by the humidity sensor 7 is larger than the third set value, the microcomputer 11 performs an arithmetic process to stop the operation air volume and outputs it to the fan motor 5. Next, as shown in FIG. 5 (a), when the determined operating air volume is weak, the controller 6 determines that the air volume ratio of the outlet A8 and the outlet B9 is 50% and the air volume ratio of the outlet C10 is 0%.

  Further, the ratio of the air volume at the outlet can be adjusted to the convenience of the user.

  In addition, the user can be notified of the setting of the air volume ratio at the outlet.

  Since the air volume hitting the human body can be reduced by controlling the air volume ratio at the outlet, it can also be applied to air volume control of air conditioners such as air conditioners and dehumidifiers used in living spaces.
