Abstract
This invention provides a combined washing machine in which pulsator type and drum type washing machine features are united such that they can be selectively utilized depending upon a desired washing condition, thereby executing optimal washing operation. The combined washing machine comprises a washing drum having both of a plurality of lifters, as in a drum type machine, and a pulsator, as in a pulsator type machine, and being rotatable through 90.degree. between vertical and horizontal positions by means of a driving device.
Claims11
A combined pulsator and drum type washing machine comprising:
- a washing drum having a plurality of lifters provided on its inner periphery and a pulsator rotatably disposed on its inner bottom;
- a washing drum motor for driving said washing drum;
- a pulsator motor for driving said pulsator;
- a tub surrounding said washing drum;
- fixing members each having a bearing shaft for turning said tub and secured to the opposite sides of the outer periphery of said tub;
- bearing housings for rotatably guiding and supporting said bearing shafts to permit said tub to be turned smoothly;
- means for rotating one of said bearing shafts to turn said tub between upright and horizontal positions for selectively washing in one of a plurality of washing modes;
- and
- a power supply control means for controlling rotational directions and driving of said washing drum and said pulsator motor.
A method of driving a combined pulsator and drum type washing machine including a washing drum having a pulsator and lifters, a washing drum motor for driving said washing drum, and a pulsator motor for rotating said pulsator, the method comprising the steps of:
- selectively supplying power to said washing drum motor and said pulsator motor, and, based on said selectively supplied power,
- rotating said pulsator and said washing drum in opposite directions each other during pulsator type washing operation,
- rotating only said drum during drum type washing operation, and
- rotating said pulsator and said drum in the same direction during dehydration.
A method of carrying out a washing operation for a small quantity of laundry by a combined pulsator and drum type washing machine including a washing drum having a pulsator and lifters disposed within a tub, the method comprising the steps of:
- slantingly arranging said tub at a predetermined one of a number of angles of inclination so as to permit the laundry and washing water in said washing drum to be collected at a lower corner portion of said drum, and then
- rotating said pulsator with said drum held in such an inclined position.
