  • the laundry treatment device of the present invention can immediately perform the changed course without re-sensing the laundry weight even if the course is changed if there is no history of opening and closing the door 14 and laundry weight detection has been performed. As a result, the laundry treatment device of the present invention can prevent water and energy waste while also preventing washing delays.

  • the information display step (D7) is performed to immediately display information on the changed course or option.
  • the information display step (D7) may display course or option information based on the initially detected weight. For example, in the information display step D7, the name and changes of the changed course or option, and the expected execution time of the course or option corresponding to the existing weight may be displayed on the display unit 800.
  • the re-detection step (D5) can be skipped and the information display step (D7) can be performed immediately, even if the course or option has changed.
  • the laundry treatment device of the present invention utilizes the fact that there is no change in the laundry weight if the door is not opened or closed even if the course or option is changed, and can utilize the laundry weight data stored in the storage unit (S) based on the first course.
  • the execution input step (D8) and the course execution step (D9) are performed so that the clothing treatment device can be newly operated with the changed course or option.
