first embodiment

[0063]FIG. 6 is a flow chart illustrating a washing method according to the first embodiment of the present invention. Referring to FIG. 6, if a washing stroke starts, the controller 700 senses the volume of the laundry (S10). The controller 700 repeatedly rotates the drum 300 in forward and reverse directions to sense the volume of the laundry. The controller 700 determines the volume of the laundry based on load and rotational speed of the drum 300 detected when the drum 300 is rotated. Another methods of determining the volume of the laundry may be applied to the present invention.

[0064] If the volume of the laundry is determined, the controller 700 selects various washing options depending on the volume of the laundry (S20). For example, the controller 700 can determine the volume of the washing water (first water level) to be used for a preliminary washing stroke, the volume of the washing water (second water level) to be used for a main washing stroke, duration of the washing...

second embodiment

[0073]FIG. 7 is a flow chart illustrating a washing method according to the second embodiment of the present invention. Referring to FIG. 7, if a washing stroke starts, the controller 700 determines the volume of the laundry (S110) and selects various washing options depending on the volume of the laundry (S120). For example, the controller 700 can set the volume of the washing water (first water level) to be used for the preliminary washing stroke, the volume of the washing water (second water level) to be used for the main washing stroke, number of times / duration of the rinsing stroke, number of times / duration of the dehydrating stroke, duration of the preliminary washing stroke (first set time), duration of the main washing stroke (second set time), and so on depending on the volume of the laundry.

[0074] Then, the controller 700 carries out the preliminary washing stroke using the steam and the washing water of the first water level during the preliminary washing stroke duration...

Abstract

A washing machine and a washing method thereof are disclosed, in which waste of washing water is reduced and washing efficiency is improved. The washing method includes the steps of determining the volume of laundry in a tub, setting a first water level for a preliminary washing stroke and a second water level for a main washing stroke based on the determined volume of laundry, carrying out the preliminary washing stroke using washing water of the first water level and steam, and converting the preliminary washing stroke into the main washing stroke based on washing water of the second water level depending on an inner temperature of the tub.
