The first state is a state in which the rotating part stops the humidifying rotor in a position where the humidifying filter is not immersed in the water. The blower according to claim 2, wherein the second state is a state in which the rotating part rotates the humidifying rotor and immerses the humidifying filter in the water.
  4. When the blower is operating for the purpose of humidification, the control unit rotates the humidifying rotor at a first frequency to immerse the humidifying filter in the water. The blower according to claim 3, wherein the second state is a state in which the rotating part rotates the humidifying rotor at a second frequency lower than the first frequency.
  5. The humidifying unit includes a humidifying rotor equipped with the humidifying filter, The supply unit comprises a tray for storing the water and a rotating unit for rotating the humidifying rotor. The first state is a state in which the rotating part stops the humidifying rotor in a position where the humidifying filter is not immersed in the water. The blower according to claim 2, wherein the second state is a state in which the rotating part stops the humidifying rotor at a position in which the humidifying filter is immersed in the water.
  6. Equipped with a news department, The humidifying unit includes a tray for storing water supplied to the humidifying filter, The blower device according to claim 1, wherein the control unit acquires the water level, and if the humidifying filter is not dirty, causes the notification unit to issue a notification prompting the addition of water when the water level falls below a first water level, and if the humidifying filter is dirty, causes the notification unit to issue the notification when the water level falls below a second water level higher than the first water level.
  7. Equipped with a news department, The air blower according to claim 1, wherein the control unit causes the notification unit to notify the notification unit that the humidifying filter is dirty when the air blower is operating for purposes other than humidification.
  8. The humidifying unit comprises a tray for storing water supplied to the humidifying filter, and a detection unit for detecting whether or not water is stored. The blower according to any one of claims 1 to 7, wherein the control unit determines whether the humidifying filter is dirty based on the time during which the detection unit detected that water was stored after the humidifying filter was attached to the blower.
  9. The blower according to any one of claims 1 to 7, wherein the control unit determines whether the humidifying filter is dirty based on the time the blower has performed humidification or the amount of humidification performed by the blower.
  10. The blower according to any one of claims 1 to 7, wherein the control unit determines whether or not the humidifying filter is dirty based on the humidifying power of the blower.
  11. Equipped with a sensor that detects the intensity of the musty smell, The blower according to any one of claims 1 to 7, wherein the control unit determines whether or not the humidifying filter is dirty based on the strength.

Description

This disclosure relates to a blower. In humidifiers, the air may be humidified by supplying water to a humidifying filter through which the air passes. Patent Document 1 discloses a humidifying air purifier.
