Definitions

  • the present invention relates to a washing machine comprising a tub, a drum mounted for rotation within the tub to receive laundry to be washed and a controller for controlling rotation of the drum.
  • the invention also includes a method of controlling such a washing machine.
  • a drum type washing machine washes laundry contained in a drum by operating a drum motor to rotate the drum and agitate the laundry in detergent and water.
  • a conventional drum-type washing machine has a drum rotatably mounted within a tub. Water supplied to the tub enters the drum through holes located therein. However, as there is a gap between the inner circumference of the tub and the outer circumference of the drum, the water must first fill this before it enters the drum to wet laundry in the drum. It therefore takes a long time to uniformly wet laundry in the drum.
  • Lifting elements or paddles on the inner circumference of the drum extend in a longitudinal direction parallel to the axis of rotation of the drum. To agitate the laundry, the lifting elements lift laundry, as the drum rotates and causes it to drop under gravity when the laundry reaches the upper part of the drum, thereby washing the laundry.
  • a conventional drum type washing machine determines the rotation speed of the drum based on the weight of the laundry and then operates the drum based on this rotational speed, the laundry carried by the lifters may drop either before or after the laundry reaches the top position of the drum. Therefore, the laundry is not agitated as much in comparison to when the laundry is allowed to drop from the top of the drum, thereby reducing the washing effect and requiring a longer time to wash the laundry.
  • the present invention seeks to provide a system which overcomes or substantially alleviates the problems discussed above.
  • a drum type washing machine is characterised by a position sensor for generating a signal indicative of when the rotational position of the drum relative to the tub corresponds to a predetermined rotational position, the controller controlling rotation of the drum in dependent on the signal received from the position sensor.
  • the position sensor is operable to generate a signal when the rotational position of the drum relative to the tub corresponds to a first predetermined rotational position, to cause the controller to reduce the speed of the drum and, to main that signal until the rotational position of the drum relative to the tub corresponds to a second predetermined rotational position, to cause the controller to increase the speed of the drum.
  • the drum may include at least one lifting element and the drum includes a rotational position in which the or each lifting element is at top-dead centre during each revolution of the drum, the first predetermined rotational position corresponding to a position just before the, or one, lifting element has reached top-dead centre.
  • the second predetermined rotational position corresponds to the rotational position of the drum when the, or one, lifting element is at top-dead centre.
  • the controller is operable to cause the drum to stop for a predetermined length of time when it has reached the second predetermined position, before increasing the speed of the drum.
  • the washing machine may include a water inlet positioned above the drum, the controller being operable to initiate a flow of water through the inlet when the controller has stopped rotation of the drum for said predetermined length of time so that at least some of the water enters the drum through the lifting element at top-dead centre.
  • a method of controlling a washing machine according to the invention is characterised by the steps of:
  • the lifter may include a main body, incoming holes formed through the main body for receiving the supplied water, and spray holes formed through the main body for spraying the wash water into the drum.
  • the method includes the steps of:
  • the method includes the further step of stopping rotation of the drum for a predetermined length of time when it has reached the second predetermined position and before increasing the speed of the drum.
  • FIG. 1 and 2 there is shown in Figures 1 and 2 a drum type washing machine in accordance with the present invention comprising a housing 1 having a nearly cubic shape defining an external appearance, a tub 2 for containing water, a drum 3 rotatably installed in the tub 2 and provided with a plurality of holes 4 formed therethrough, and a drum motor 5 for rotating the drum 3 to wash laundry.
  • the drum motor 5 includes a stator 5a and a rotor 5b.
  • Openings 2a and 3a are respectively formed through the front surfaces of the tub 2 and the drum 3 and a door 6 for opening and closing the openings 2a and 3a is hinged to a front surface of the housing 1.
  • a water supply pipe 7 for supplying water from the outside to the washing machine and a detergent container 8 for mixing a detergent with the water supplied through the water supply pipe 7 are installed in an upper part of the housing 1 and a drain pump 9 and a drain hose 10 for discharging the water to the outside of the housing 1 after the washing operation is completed are installed on a lower part of the housing 1.
  • the drum 3 and the tub 2 are upwardly inclined at a designated angle towards the front surface of the housing 1.
  • a plurality of lifters 11, 12 and 13 are installed on the inner circumference of the drum 3 such that the lifters 11, 12 and 13 are spaced from each other by designated intervals.
  • the lifters serve to lift the laundry loaded in the drum 3 together with the water to a designated height. The laundry then drops due to the rotation of the drum 3 thereby allowing the laundry to be washed.
  • the lifter 11 includes a main body 11a having a trapezoidal shape for defining an external appearance, a longitudinal inlet recess 11b formed through the upper surface of the main body 11a for receiving the supplied water, a plurality of spray holes 11c formed through the lower and side surfaces of the main body 11a for spraying the water into the drum 3 to wet the laundry, and connection holes 11d formed through the upper surface of the main body 11a for connecting the lifter 11 to the drum 3 using screws 11e.
  • the drum type washing machine consistent with the present invention sprays water directly from the upper part of the drum 3 thereby allowing the laundry contained in the drum 3 to be uniformly and rapidly wetted.
  • the drum type washing machine further comprises a controller 20 for controlling the overall operation including the water supply mode and the wash mode.
  • the controller 20 controls a motor driving unit 22 which drives the drum motor 5 based on input instructions from a user through an input unit 21, thereby transmitting the driving force of the drum motor 5 to the drum 3 and then rotating the drum 3 at a designated speed.
  • a speed sensor 23 senses the rotational speed of the drum motor 5 and supplies the sensed speed to the controller 20.
  • An encoder 24 senses the angle of rotation of the drum 3 and supplies the sensed angle to the controller 20.
  • the encoder 24 is installed in the tub 2 such that the encoder 24 generates a designated pulse signal by means of a magnetic force generated from magnets (not shown) installed on the outside of the drum 3 when the drum 3 is rotated.
  • a magnet having a comparatively large magnetic force, as compared to the other magnets installed on the drum 3, is installed at a predetermined standard position.
  • the intensity of a standard pulse signal outputted from the encoder 24 by means of the comparatively large magnetic force of the above magnet is higher than the intensities of the pulse signals outputted from the encoder 24 by means of the magnetic force of the other magnets.
  • the encoder outputs a plurality of standard pulse signals based on the standard position to respectively correspond to the plurality of lifters during one revolution of the drum
  • the encoder may output only one standard pulse signal, based on the standard position, to correspond to any one lifter of the plurality of lifters per one revolution of the drum.
  • the controller 20 controls the motor driving unit 22 to drive the drum motor 5 so that the one of the lifters 11 is disposed under the water supply pipe 7. That is, the controller 20 controls the angle of the drum 3 based on the standard pulse signal outputted from the encoder 24. Subsequently, when the water is supplied to the inside of the drum through the water supply pipe 7 it falls into the longitudinal inlet recess 11b of the lifter 1 and is sprayed into the drum 3 through the spray holes 11c.
  • the controller 20 operates the drum 3 at a first rotational speed (S1).
  • the encoder 24 outputs a pulse signal having a low intensity (M2).
  • the encoder 24 outputs a standard pulse signal having a high intensity (M1) and then the controller 20 reduces the rotational speed of the drum 3.
  • the controller 20 increases the rotational speed of the drum 3 to the first rotational speed (S1) and maintains the first rotational speed of the drum 3 to the first rotational speed (S1) and maintains the first rotational speed (S1) of the drum 3.
  • the rotational speed of the drum 3 is decreased to the second rotational speed (S2).
  • the rotational speed of the drum 3 is increased to the first rotational speed (S1) and maintained at the first rotational speed (S1). Whenever the drum 3 turns one revolution, the above described process is repeated.
  • the controller 20 decreases the rotational speed of the drum 3 and allows the laundry carried by the lifter 11 to drop from the top position (C).
  • the drum of the washing machine may be rotated alternately in the clockwise and counter-clockwise directions during the wash mode, and whenever a lifter reaches the top position, the laundry carried by the lifter is allowed to fall by the force of gravity, thereby maximising falling power.
