Abstract
A washing machine includes a drum, a water supply device, and a controller. The drum accommodates laundry, and the water supply device supplies water to the inside of the drum. The controller controls supply of water so that water is supplied into the drum from when rotational speed of the drum reaches a first predetermined speed, is decelerated and reaches a second predetermined speed, to when the rotational speed of the drum reaches to a third speed more than the second speed and less than the first speed, in a spin-drying cycle.
Claims25
A washing machine comprising:
- a drum accommodating laundry;
- a water supply device supplying water to the inside of the drum;
- and
- a controller controlling supply of water so that water is supplied into the drum from when the rotational speed of the drum reaches a first predetermined speed, to when the rotational speed of the drum is decelerated, reaches a second predetermined speed and then reaches a third speed more than the second speed and less than the first speed, in a spin-drying cycle.
A control method of a washing machine comprising:
- injecting water into a drum accommodating laundry using an injection nozzle from when the rotational speed of the drum reaches a first predetermined speed in a spin-drying cycle;
- and
- stopping injection of water into the drum when the rotational speed of the drum is decelerated and reaches a second predetermined speed and then the rotational speed of the drum reaches to a third speed more than the second speed and less than the first speed.
A control method of a washing machine, comprising:
- draining water from a tub to outside the washing machine;
- driving a drum of the washing machine at an accelerated speed;
- sensing an RPM of the drum;
- judging whether or not the rotational speed of the drum reaches a first reference speed, and stop driving the drum upon judging that the rotational speed of the drum reaches the first predetermined reference speed;
- during deceleration of the drum after stopping the driving of the drum, begin injecting water into the drum;
- re-driving the drum motor to a second reference speed;
- judging whether or not the rotational acceleration of the drum is greater than a predetermined reference acceleration;
- upon judging that the rotational acceleration of the drum is greater than the predetermined reference acceleration, stopping injection of water into the drum;
- accelerating the drum to a maximum speed;
- and
- stopping the driving of the drum.
