  • the controller 300 In operation, when a user selects a desired washing course using the key-input part 100 and inputs an operation command, the controller 300 outputs a control command so that a cycle may be performed according to the selected course.
  • the controller 300 controls to perform detection of water amount first to set a water level according to the detected water amount and controls water to be supplied so as to reach the set water temperature according to the selected course.
  • the washing water reaches the set temperature and level, the supplying of the washing water stops and the pulsator regularly operates to perform a washing cycle.
  • the washing cycle finishes the washing water is drained to the outside along a drain hose and clean washing water is supplied again.
  • a rinsing cycle is performed.
  • a spinning cycle is performed, so that all of the washing cycles are completed.
  • FIG. 2 is a diagram illustrating a water-supply process according to a method of controlling water in a washing machine supply according to the present invention.
  • the washing water is supplied over at least two steps according to the inventive method of controlling water supply in the washing machine. Hot water and cool water are selectively or simultaneously supplied in each of the washing cycles.
  • the cool water and the hot water are simultaneously supplied during a primary water-supply interval A and on only the hot water is supplied during a secondary water-supply interval B.
  • the heater 600 is selectively controlled to operate depending on water temperature.
  • the pulsator (not shown) can be controlled to perform an agitation motion by driving the motor 700 simultaneously with the heater 600 .
