It is feasible that a water level of a tub is considered before deciding whether to allow the door to open or not.
  • the method of controlling opening and closing of the door in the drum- type washing machine comprises the steps of: operating the drum-type washing machine; locking the door not to open; sensing the water level of the tub when the drum- type washing machine stops operating; and releasing a door-lock so that the door becomes ready to open if the water level of the tub is sensed lower than predetermined height.

  • One side of the door 1 is connected to the cabinet cover 6 with a hinge and the other side of the door 1 hangs a hook 8.
  • the hook 8 fixes the door 1 by meeting a latch assembly 9 in the cabinet cover 6.
  • the latch assembly 9 is regulated by the controller in the control panel unit 5.
  • the controller impresses or interrupts an electric current to a door-lock-switch (not shown) and commands its function.
  • the latch assembly 9 accordingly runs and controls opening and closing of the door.
  • a child-lock-button 10 is on the control panel unit 5. As a user pushes the child- lock-button 10, a signal is delivered to the controller. After receiving the signal, the controller orders the latch assembly 9 to work and the door 1 is laid in a locking condition. [37] A child-lock is required to keep a child from entering the drum 3 after opening the door 1. [38] The control panel unit 5 has a door-opening-lamp 11 and a door-closing-lamp 12, which inform the user whether the door 1 can be opened or not. [39] [40] Referring to Fig.
  • a method of controlling opening and closing of the door in the drum-type washing machine comprises the steps of: operating the drum- type washing machine at step SlO with manipulation by the user after laundry is loaded in the drum 3; locking the door 1 at step S20 by impressing the electric current to the door- lock-switch before or after or simultaneously with step SlO and by working the latch assembly 9; sensing whether the drum-type washing machine stops in operation at step S30; sensing the water level of the tub at step S40 when the drum-type washing machine stops operating; and releasing the door-lock at step S50 so that the door 1 becomes ready to open by the latch assembly 9 if the water level of the tub is sensed lower than predetermined height.
  • the step S20 of locking the door impresses the electric current to the door- lock-switch and converts the door into locking. In addition, it turns on the door- closing-lamp 12.
  • the step S30 of sensing the stop implies both the cases that the user puts a stop to the operation of the drum-type washing machine and the drum-type washing machine unexpectedly stops without manipulation by the user.
  • the former is, for example, the user turns off a power to put more laundry into the drum 3 before water is drained.
  • the latter is that the drum-type washing machine becomes stopped due to a cut-off of the power, a mistake by the user or the incapacity of motor.
  • the step of S40 sensing the water level reads the water level contained in the tub and decides whether the door-lock is released.
  • the step of S50 releasing the door-lock interrupts the electric current to the door- lock-switch and makes the latch assembly 9 remove the door-lock when the water level of the tub is lower than predetermined height.
  • the controller turns on the door-opening-lamp 11 and turns off the door- closing-lamp 12 at a time, the user can notice the door 1 is available to open at step S50.
  • the drum-type washing machine is turned out to be in normal operation at step S30, it is returned to step SlO and continues operating.
  • Fig. 3 is the flow chart of the method of controlling opening and closing of the door in the drum-type washing machine in accordance with the 2nd embodiment of the present invention.
  • the 2nd embodiment is developed from the 1st one by adding a function of the child-lock.
  • the method of controlling opening and closing of the door in the drum-type washing machine comprises the steps of: operating the drum-type washing machine at step Sl 10 after the child- lock-button 10 is on and the child-lock is set up at step SlOl; locking the door at step S 120; sensing whether the drum-type washing machine stops in operation at step S 130; sensing the water level of the tub at step S 140 when the drum-type washing machine stops operating; checking the child-lock to be released by manipulation of the child-lock-button at step S 150 when the water level of the tub is lower than predetermined height; releasing the door- lock to be opened at step S 160 when the child- lock-button is released; and turning off the door-closing-lamp and turning on the door-opening-lamp at step S 161 after the door-lock comes to released.
  • step S 120 As the user puts into operation of the child-lock, the door has been already locked at step Sl 10. In addition to that, the door is automatically locked depending on the operation of the drum-type washing machine, a double-lock-system is executed at step S 120. [54] Since the child-lock has priority over any other control, the door maintains the locking condition in any cases if the child-lock is on, regardless of the door- lock-switch-off. [55] The latch assembly functions the child-lock by the controller in the embodiment, though the latch assembly and a separate locking device can be installed in the drum- type washing machine in order to implement the child-lock. [56] Releasing the child-lock by the user is confirmed at step S 150.

  • Fig. 5 is the flow chart of the method of controlling opening and closing of the door in the drum-type washing machine in accordance with the 4th embodiment of the present invention.
  • the 4th embodiment includes, contrary to the 2nd one, the child-lock is off before the drum-type washing machine is in operation at step S300 and the child-lock is on after its operation at step S301.
  • the method of controlling opening and closing the door in the drum-type washing machine according to the 3rd embodiment comprises the steps of: operating the drum- type washing machine at step Sl 10 while the child-lock-button is off at step S300; locking the door and turning on the door-closing-lamp at step S 120; automatically turning on the child- lock at step S301; sensing whether the drum- type washing machine stops in operation at step S 130; sensing the water level of the tub at step S 140 when the drum- type washing machine stops operating; checking the child-lock to be released by manipulation of the child- lock-button at step S 150 when the water level of the tub is lower than predetermined height; releasing the door- lock to be opened at step 160 when the child- lock is released; and turning off the door-closing-lamp and turning on the door-opening-

  • the further explanation is excluded since the rests are identical with the 4th embodiment.
  • the method of controlling opening and closing of the door in the drum-type washing machine has the practical strength: [74] When the drum-type washing machine becomes stopped without finishing washing, the water level of the tub is sensed. Then, the door is opened only if the water level of the tub is lower than predetermined height. It can be prevented that water flows out caused by accidentally opening the door. [75] The user can clearly understand the condition of the drum-type washing machine since a lamp indicates that the door can be opened or should be locked depending on the water level of the tub. [76] When the drum-type washing machine stops in operation with the child-lock-on, the door- lock is released after the child- lock is released, even though the water level of the tub is under predetermined height.

Abstract

La présente invention concerne un procédé de commande de l'ouverture et de la fermeture de la porte d'un lave-linge à tambour. Lorsque le lave-linge à tambour s'arrête brutalement pendant son fonctionnement, par exemple en cas d'erreur commise par un utilisateur ou de mise hors tension, un niveau d'eau dans la cuve est détecté, lequel niveau se révèle inférieur à une hauteur prédéterminée. Un système de verrouillage de la porte est ensuite modifié de façon que la porte puisse être ouverte. Cette invention vise ainsi à empêcher que l'eau ne s'échappe de la cuve au cas où l'utilisateur ouvrirait la porte par erreur.
