The drum is provided with an access or loading port situated on a portion of the cylindrical side surface thereof, and at least a flap for closing/opening the drum access port. There is also provided a top lid adapted to close the aperture into the wash tub from above, and hinged with an edge portion thereof on the upper rear edge portion of the outer casing of the machine. The machine is provided with interference means applied on to a portion of the machine comprised between the drum and the top lid, and adapted to be rotated upwards when the drum flap is opened, thereby interfering with the top lid. As a result, the interference means will act to make it impossible for the top lid to be closed if the drum flap is not duly closed.

  • Publication number: 20120011891
    Abstract: A drum type washing machine has a cabinet forming an outer appearance of the washing machine, a tub fixed inside the cabinet for storing the washing water, a drum disposed in the tub and having both side surfaces supported by the cabinet to be rotatable and an inlet through which laundries come in/go out on a circumferential surface thereof, and a driving motor fixed on one side surface of the drum to rotate the drum. Washing capacity can be increased while maintaining the entire size of the washing machine by increasing a diameter of the drum without increasing the size of the cabinet, and the entire size of the washing machine can be compacted by minimizing the installation space of the driving motor.

  • Patent number: 8046855
    Abstract: A method and control system for automatically halting operation of a washing machine by stopping operation of the washing machine motor is provided. The washing machine that implements the method includes a motor controller having a primary microprocessor and a secondary microprocessor which serves as a backup redundancy processor in the event there is a malfunction with the primary microprocessor or the primary microprocessor fails to halt washing machine operation within a prescribed window of time. The primary microprocessor controls operation of all of the washing machine electrically controlled components. The secondary microprocessor is electrically connected to a lid switch and the washing machine motor and is configured to halt operation of the motor in response to the primary microprocessor failing to halt motor operation after the lid is open.

  • Patent number: 7856854
    Abstract: An appliance with a hazardous device contains a first controller controlled by a first control element which, in turn, is controlled by a second controller by use of a first switching element. An electrically controllable protection device is provided and is controlled by a second control element, it is possible to deactivate the protection device. A storage capacitor is provided between the first and the second control element and supplies the second control element with energy for a control pulse and is charged by the first control element when the first controller is switched off and is discharged by the first switching element when the first controller is switched on. This circuit generates a safe control circuit. In the event of a possible hazardous state, either the first controller is no longer supplied with energy or the protection device cannot be deactivated, and so danger to a user is precluded.
