Abstract

Provided is a washing method. The washing method includes: setting a target water level of washing water supplied for a washing cycle; supplying washing water and measuring a time for the washing water to reach the target water level; and setting a spray time for a rinsing cycle conducted after the washing cycle based on the time measured in the step of measuring a time to reach the target water level. Adequate rinsing performance can be achieved even in a region with different water pressure.

Claims (12)

1. A washing method comprising:

measuring an amount of laundry in an inner tub;

operating a washing cycle that includes:

setting a target water level, a reference value and a spraying time according to the measured amount of the laundry;

filling the inner tub, through a detergent box, with washing water introduced from an external water source, until a water level in the inner tub reaches the target water level, and measuring a time taken for the water level to reach the target water level;

adjusting the spraying time based on a difference between the measured time and the reference value; and

washing the laundry by rotating at least one of the inner tub and a pulsator; and

operating a rinsing cycle that includes spraying, through one or more nozzles, washing water introduced from the external water source into the inner tub for a period of the adjusted spraying time, and rotating the inner tub and draining the inner tub,

wherein the reference value is set as a time for the water level to reach the target water level when the washing water introduced from the external water source with a given constant pressure.

2. The washing method of claim 1 , wherein adjusting the spraying time includes increasing the spraying time when the measured time is greater than the reference value.

3. The washing method of claim 1 , wherein adjusting the spraying time includes decreasing the spraying time when the measured time is less than the reference value.

4. The washing method of claim 1 , wherein an adjusted amount of the spraying time is proportional to the difference between the measured time and the reference value.
