  • the drum 30 may rotate right before making one revolution.
  • the drum 30 may be rotated up to or less than an angle at which the laundry is separated from an inner wall of the drum or the disposition is varied. Accordingly, while the position of the laundry in the drum 30 is varied, unnecessary loads or impacts may be restricted from being transmitted to the drive portion 9. Accordingly, the controller P may accurately calculate the load of the laundry through a current value applied to or output from the drive portion 9.

  • the controller P may calculate (process) an amount of the laundry by measuring a current value applied to or outputted from the drive portion 9 in the rotating step D 1.
  • Te is a torque value applied to the drive portion 9 and corresponds to 'I (current value) ⁇ K (drive portion constant)'. That is, since the drive portion constant k is an eigenvalue of the drive portion 9 itself, the controller P may calculate a torque value applied to the drive portion 9 when detecting the current value I.
  • Bw is a friction torque, and when the drum 30 rotates, B becomes very small, so it may be ignored.
  • the controller p may detect an angular acceleration when rotating the drum in the rotating step d1.
  • the angular acceleration may also be directly calculated through a current value applied to the drive portion 9.
  • both the torque value Te applied to the drive portion 9 and the angular acceleration dw/dt may be calculated, and thus an inertial moment J may be calculated.
  • the laundry treating apparatus of the present disclosure may immediately detect the amount of the laundry by grasping the inertial moment J.
  • FIG. 19 shows a process for calculating a laundry amount with an inertia moment in a laundry treating apparatus of the present disclosure.

  • the weight of the laundry is obtained, it is able to detect an inertia moment generated when the laundry is rotated in the drum 30. If the inertia moment is obtained, it is able to detect the weight of the laundry.
  • the controller P detects the inertia moment as 55000 in the calculating step D3, when the drum 30 is rotated counterclockwise, an amount of the laundry may be confirmed as 2kg. When the drum 30 is rotated clockwise, the amount of the laundry may be confirmed as 3kg.
  • the controller p may immediately detect the amount of the laundry through data obtained by arranging the inertial moment and the weight of the laundry stored in the storage portion p2 based on a diameter of the drum 30, a rotation direction of the drum 30 and the like.
  • the controller P may detect the amount of the laundry by detecting only a current value applied or output in the rotating step D 1. That is, the calculating step D3 may be performed during the rotating step D1 or at the moment when the rotating step D1 is terminated.
  • the rotating step D1 and the calculating step D3 may be completely performed before the position of the drum 30 is restored to the original position. That is, the calculating step D3 may already be terminated before the restoring step D2 is terminated.
  • the rotating step D1 and the calculating step D3 may be entirely performed within 0.3 to 1 second, and the laundry amount detecting step itself may be performed within 0.3 to 1 second.
  • the controller P may detect the laundry amount in an instant so that a user hardly feels the time for detecting the laundry amount and provide an execution time of a selected course or option.
  • the controller P may calculate and display an execution time or detergent amount of a course or option corresponding to the laundry amount almost at the same time.
  • the rotating step D1, the calculating step D3, and the displaying step D4 may be entirely performed before the position of the drum is restored.
  • the rotating step D1, the calculating step D3, and the displaying step D4 may be entirely performed within 0.3 to 1 second.
  • the related art laundry treating apparatus detects a laundry amount after a course or option has been executed, a user cannot recognize the amount of the laundry until the course or option is selected and executed.
  • the related art laundry treating apparatus rotates a drum at least one rotation or more when detecting a laundry amount, it is unable to quickly perform laundry amount detection, and thus the laundry amount is displayed relatively late even after execution of a course or option.
  • a user in case of the related art laundry treating apparatus, a user usually leaves the laundry treating apparatus without waiting until detecting a laundry amount after executing a course or option, thereby failing to check an execution time or end time of the course or option.
  • laundry treating apparatus Accordingly, the user often has to visit the laundry treating apparatus to check the end of the course or option.
  • laundry is left in the drum for a long time even after the course or option is terminated, causing wrinkles in the clothes, or in severe cases, decomposition of the laundry may occur.
  • the related art laundry treating apparatus performs the locking of a door when a course or option is executed, a user cannot adjust a laundry amount thereafter.
  • a laundry treating apparatus of the present disclosure may detect and display a laundry amount before execution of a course or option.
  • a user may recognize a laundry amount before executing a course or option and input a detergent in consideration of an appropriate detergent amount corresponding thereto. For example, a user may check a detergent amount corresponding to a laundry amount displayed on a detergent container, and may put the checked detergent into the laundry treating apparatus.
  • the laundry treating apparatus of the present disclosure can save a detergent, solve the problem of excessive detergent remaining in the laundry after the end of a course, and prevent environmental pollution.
  • the laundry treating apparatus of the present disclosure detects a laundry amount by rotating a drum less than one revolution, even if the laundry amount is detected before execution of a course or option, it does not cause washing delay and the like or inconvenience to a user.
  • a laundry amount is detected and displayed within 3 seconds, so that a washing delay is not caused.
  • the laundry treating apparatus of the present disclosure may detect a laundry amount before executing a course or option and display an estimated time or an end time of the course or option corresponding to the laundry amount.
  • a user may recognize an estimated time or an end time of each course or option.
  • the user may select a course or option suitable for a current schedule.
  • a user may recognize an estimated time or end time of a course or option before executing the course or option. Therefore, since the user checks the estimated time or the end time and then executes the course or option, it is possible to reduce the trouble of checking the laundry treating apparatus until the end of the course or option. Furthermore, since the user can recognize the end time of the course or the option, it is possible to restrict laundry from being left inside a drum after the end of the course.
  • the laundry treating apparatus of the present disclosure does not lock the door before executing a course or option, a laundry amount is detected and displayed before the door is locked. Accordingly, a user may further put or withdraw laundry by checking the displayed laundry amount.
  • the laundry treating apparatus of the present disclosure quickly detects a laundry amount, and thus displays the laundry amount or an estimated execution time before executing a course or option or locking a door, thereby deriving the aforementioned remarkable effects.
