At this time, when the power of the fan assembly 6 has been already turned off, an operation of turning off the power of the fan assembly 6 may be omitted and the humidifying operation may be immediately terminated.
  • the vent valve 317 may be opened in operation S44.
  • the vent valve 317 may be opened for a predetermined time set in advance.
  • the control unit may determine whether the opening time of the vent valve 317 has passed the predetermined time in operation S45, and when it is determined that the opening time of the vent valve 317 has passed the predetermined time, the vent valve 317 may be closed and locked in operation S46. By doing this, the operation related to a case in which the pump 5 is operated in the state in which the water tank 3 is not mounted may be terminated.
  • the water tank 3 may be forcibly separated even during the operation of the humidifying apparatus 1, and therefore the operation related to the case in which the pump 5 is operated in the state in which the water tank 3 is not mounted in operations S40 to S48 may be performed even during the operation of the humidifying apparatus 1 as well as before the humidifying apparatus 1 starts to perform the operation.
  • the humidifying apparatus 1 may be operated in conjunction with a smart device.
  • a user may control the operation of the humidifying apparatus 1 using the smart device, and the state of the humidifying apparatus 1 may be displayed through the smart device.
  • the related information may be displayed on a user's smart device.
  • a cumulative operating time of the humidifying apparatus 1, a daily operating time of the humidifying apparatus 1, a temperature or humidity of a space in which the humidifying apparatus 1 is installed, and the like may be displayed on the user's smart device.
  • the user may run or stop the operation of the humidifying apparatus 1 through a manipulation of the smart device from the outside of the space in which the humidifying apparatus 1 is installed.
  • the user may run or stop the operation of the humidifying apparatus 1 using the information displayed on the smart device.
  • water from which minerals, organic matter, and the like are removed may be supplied to the humidifying unit, so that the humidifying unit may be prevented from being contaminated.
  • the contamination of the humidifying unit may be prevented, and therefore a user may easily maintain and manage the humidifying apparatus.
