Definitions

  • the present invention relates to a method which tests the operation of washing and drying machines.
  • the patent document no KR20070056288A discloses a motor failure detection method and system for a washing machine.
  • the washing machine comprises a system which measures the rotation speed of the motor and shows the measured value on a display. Thanks to said system, the rotation speed of the motor is controlled; thus it can be controlled whether the motor has a problem or not.
  • the other patent document no WO2008154711A2 of the state of art discloses a washing machine which can be operated with a delay pre-determined by the user.
  • the user determines a delay time for the operation of the machine via a button.
  • Said button also can be used for setting the machine in a test mode. The water valves, the motor and the pump of the machine are tested in the test mode.
  • the present invention discloses an error detection method for a washing and/or drying machine comprising at least one control element; at least one warning means; at least one drum in which laundries are placed; at least one motor giving motion to said drum; at least one electronic control unit arranging the operation of the machine; and at least one door for placing the laundries into the drum.
  • Said method comprises the steps of starting the test operation by means of detecting the usage of the control elements in a determined order and/or combination via said electronic control unit in a software manner; rotating the drum firstly at a direction in a predetermined rotational speed for a predetermined time, then rotating at an opposite direction of the rotated direction by means of operating the motor; detecting whether there is an error in the rotation of the drum by controlling the rotational speed of the motor via electronic control unit; if an error is detected, sending an error signal to the warning means and ending the test operation; if an error is not detected, completing the test operation.
  • the aim of the invention is to develop a method for testing the motor and the drum of a machine in washing and/or drying machines.
  • Another aim of the invention is to develop a method for detecting the motor and drum error in the washing and/or drying machines without taking the machine to the technical service.
  • Machine Control element (1, 2) Door (3) Motor (4) Drum (5) Warning means (6) Start (10) Locking the door (11) Lock control (12) Liquid control (13) Rotating the drum (14) Error control (15) Liquid discharge (16) Sending error signal (17) Sending lock error signal (18) End (19)
  • drum type washing and/or drying machines machine pieces can be failed depending on the user mistakes or environmental factors.
  • the drum of the machine and the motor giving motion to the drum can be failed by being affected to the environmental factors since they are movable pieces.
  • the present invention develops a method which detects possible errors that can be occurred in the drum and the motor in the drum type machines.
  • the washing and/or drying machine (M) which is exemplified as a washing machine in figures 1 and 2 , comprises at least one control element (1, 2) which can be preferably at least one button or switch and which sets and/or controls operation of the machine (M); at least one warning means (6) which informs the user about the operation of the machine (M); at least one drum (5) in which laundries to be washed are placed; at least one motor which gives motion to the drum (5); and at least one door (3) for placing the laundries into the drum (5).
  • Said warning means (6) can comprise at least one speaker informing the user by sound and/or at least one indicator (such as display, light) raising awareness of the user by vision.
  • the motor test operation an exemplary flow chart of which is shown in figure 3 , is started (10). Said order and/or combination are/is detected by at least one electronic control unit (not shown in figures) in a software manner which is placed in the machine (M) and arranges the operation of the machine (M).
  • at least one electronic control unit not shown in figures
  • M software manner which is placed in the machine
  • M the operation of the machine
  • said test operation by means of operating the motor (4), it is ensured that the drum (5) moves in clockwise or counterclockwise direction in a predetermined rotational speed (preferably at a 45-55 cycle range per minute, specifically 53 cycles) for a predetermined time (preferably 30-90 seconds, specifically 60 seconds) (14).
  • the motor is operated again and it is ensured that the drum (5) is moved at the opposite direction of the first direction preferably at the same rotational speed and for the same time period (14).
  • whether there is an error in the rotation of the drum (5) is controlled (15).
  • the motor (4) sends signal to the electronic control unit after each rotation and according to the sending frequency of the signal; the control unit determines the speed of the motor. Even if the determined speed is different from the predetermined speed, an error is detected.
  • an error is detected, by sending a warning signal to the warning means (6), an error in the motor (4) or drum (5) is indicated (17) and the test operation is ended (19). If an error is not detected in the drum (5) rotation, the test operation is completed (19).
  • the test operation which automatically detects the error, the noise, which may occur while the drum moves, is controlled by the tester; and the error, which cannot be detected automatically, can also be observed.
  • the drum (5) has liquid therein (13). Said controlling can be done by a liquid detector to be added in the machine (M) or by a liquid height detector present in the machine (M). If the liquid is detected in the drum (5), said liquid is discharged (16) preferably by a pump and the step of rotating the drum (14) is initiated. If there is not liquid in the drum (5), the drum is rotated directly (14).
  • the machine (M) is taken to the test mode by a remote control method preferably over a network. If errors are detected in the machine (M) as a result of the test, said errors are sent to the tester over the network. Thus; it is ensured that an error occurred in the machine (M) is remotely detected.
  • the test operation can be done only when and where the authorized people want thanks to the fact that the control elements (1, 2) are used in a certain order and/or combination for taking the machine (M) in the test mode.
  • the control elements (1, 2) are used in a certain order and/or combination for taking the machine (M) in the test mode.
