Abstract

The invention provides a drum-type washing machine. A rotary drum formed into a bottomed tubular shape is installed in a water tank such that the axis of rotation is directed from the opening front side toward the back side becoming the bottom portion horizontally or inclined downward from the horizontal direction. A control section arc-rotates the rotary drum suddenly by driving a motor suddenly at such a variation rate that the laundry is stuck to the inner surface of the rotary drum by centrifugal force, thus lifting the laundry from the lowermost position, i.e. the 0 degree position, of the rotary drum to a position over 90 degrees and less than 180 degrees. Furthermore, rotation of the motor is braked suddenly at such a variation rate that the laundry falls off the inner surface of the rotary drum, thus dropping the laundry to the side opposite to the lifting side. The control section has a forward/reverse rotation drive mode for repeating a series of such forward and reverse operations alternately.

Description

technical field [0001] The invention relates to a drum-type washing machine which drives a rotary drum installed in a water tank in such a way that the rotation axis is horizontal or inclined downward from the horizontal direction to rotate to wash laundry in the rotary drum. Background technique [0002] Figure 7 It is a cross-sectional view showing the structure of a conventional drum-type washing machine. The washing machine has a housing 31 , a water tank 32 , a rotary drum 34 , a motor 35 and a door 36 . The water tank 32 is supported in the casing 31 by a suspension structure. A rotary drum 34 having a plurality of holes 33 is disposed in the water tank 32 . The motor 35 is used to drive the rotating drum 34 to rotate. The door 36 is provided on the front side of the casing 31 . The user opens door 36 to take laundry out of rotary drum 34 or put laundry in rotary drum 34 through the front opening of water tank 32 and the front opening of rotary drum 34 . [0003]...
