Heater coupling apparatus of washing machine

A control system for a motor-driven washing machine. The control system includes an electrical motor; a driving unit that applies an input voltage to the motor to drive the motor; a voltmeter that measures a reverse voltage generated by the motor for each predetermined period; and a microprocessor reducing a speed of the motor if the measured reverse voltage is less than or equal to a predetermined voltage level.

Method of controlling motor-driven washing machine and control system for the same

A method of controlling a motor-driven washing machine. The method includes increasing a speed of a motor from zero to a first predetermined speed W. Reducing the motor speed from Wto a second predetermined speed Wand measuring the deceleration period. Increasing the motor speed from Wto a third predetermined speed Wand braking the motor according to a slow brake logic if a first interruption of the motor is ordered during the step of increasing the motor speed from Wto W. Increasing the motor speed from Wto a fourth predetermined speed Wand selecting one of plurality of rapid-brake logics on the basis of the measured deceleration period and braking the motor according to the selected rapid-brake logic if a second interruption of the motor is ordered during the step of increasing the motor speed from Wto W.

The present invention relates to laundry machines, and more particularly, to a control unit assembly in a laundry machine which enables easy assembly and accurate alignment of an input device of a printed circuit board with a button portion of a control panel. The control unit assembly includes a control panel having various operation buttons and coupling portions, a plurality of coating guides coupled to a rear surface of the control panel having fastening portions corresponding to the coupling portions, a plurality of printed circuit boards respectively mounted on the coating guides, each having an electric circuit mounted thereon, joining portions for joining the coating guides together so as to place the coating guides closer to an inside of the control panel, and holders for preventing the coupling portions and fastening portions from moving with respect to each other when the fastening portions are aligned with the coupling portions, thereby improving assembly work, preventing malfunction of the laundry machine, and permitting easy detection of an operation progress.

Laundry machine

A clothing managing apparatus is provided. In the clothing managing apparatus, a panel coupling protrusion () has a plurality of sub protrusions () for supporting a control panel () in different directions, and protrusions coupling hole portion () receives the panel coupling protrusion (). A holder () can be provided to support the control panel () and a top cover (). The holder () includes one portion () coupled to the control panel () and the other portion () coupling to the top cover ().

Clothing managing apparatus

A drum type washer is provided in which replacement of a washing ball provided in a drum lift device may be simplified, and in which a volume of the drum may be increased. The washer may include a tub, a drum rotatably provided within the tub, and a lift provided within the drum. The lift may include a base detachably coupled to an inner surface of the drum and a cover detachably coupled to the base. An exposing hole may be formed in a surface of the cover to expose a portion of the washing ball positioned between the cover and the base. A width of the cover may be gradually decreased from a rear end portion to a front end portion thereof so as to minimize a size of the lift and increase an interior volume of the drum.

Device and method for detecting malfunction of a clutch in a washing machine, the device including a clutch including a coupling for transmission of a power from a motor to a washing shaft or a spinning shaft, a clutch motor () for providing a power to the coupling, a switch for controlling the coupling, and a cam () fitted to be rotatable with the clutch motor for turning on/off the switch in response to the rotation, a power supplying part for supplying a voltage to the motor and the clutch motor (), a pulse counting part for counting a number of pulses of a voltage supplied to the clutch motor from the power supplying part, and a microcomputer for repeating a process in which the clutch motor is stopped for a second set time period (S) and operated again if the switch is not switched for a first set time period from a time the clutch motor is put into operation, and informs to a user that the clutch is in malfunction if the switch is not switched while the process is repeated equal to or more than a set times, thereby determining the clutch of being out of order and informing a result of the determination to a user.

Apparatus and method for detecting malfunction of a clutch of washing machine

Provided is an apparatus and method for controlling a washing/drying system including a washing machine and a dryer used in one pair. Since the washing machine can communicate with the dryer according to a wireless communication regulation, the dryer can operate more conveniently. According to the apparatus and method, convenience in using the washing machine and the dryer together is further enhanced.

Apparatus controlling washing/drying system wirelessly

Apparatus and method for controlling washing/drying system

A washing machine is provided. The washing machine includes an outer tub configured to store washing water, an inner tub rotatably mounted in the outer tub, a pulsator configured to form a water circulation for washing laundry, and a motor installed under the outer tub and configured to rotate the inner tub and the pulsator. The motor is configured to vary a rotation speed of the inner tub and the pulsator, such that the laundry is washed by a combination of modes. The modes including a centrifugal force washing mode, wherein the motor rotates the inner tub and the pulsator in the same direction for a first predetermined period of time, thereby creating a centrifugal force that is varied according to a variation of the ratation speed, which pushes the laundry against a wall of the inner tub, and an agitation washing mode, wherein the motor rotates the inner tub and the pulsator in the same direction at an identical speed, and then rotates the inner tub and the pulsator in a first direction for a second predetermined period of time and than in a second, reverse direction for the second predetermined period of time.
