• FIG. 1 is a block diagram of an apparatus of controlling water supply in a washing machine according to the present invention
• the apparatus of controlling water supply includes a key-input part 100 for a user to input a washing condition and select a washing course, a water- level detection part 201 for detecting a water level according to water amount, a water- temperature detection part 202 for detecting a water temperature according to the course selected by the key-input part 100, a controller 300 for controlling a relevant cycle to be performed according to the course selected by the key-input part 100, a load driver 500 for controlling operations of the heater 600 and the motor 700 according to a control signal of the controller 300, a display part 800 for displaying an operation status according to a control signal of the controller 300, and a memory device 400 for storing various reference values.
• the controller 300 controls the temperature of washing water to reach a temperature set by a course selected by a user by allowing the washing water to be supplied over a multi-step.
• the controller 300 controls the pulsator (not shown) to simultaneously perform an agitation motion by simult aneously driving a motor 700.
• 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.
• a relevant cycle is performed with the heater 600 not operated during a washing cycle interval C.
• the washing water is supplied.
• the primary water supply is performed until the waning water reaches the first set temperature set in advance according to a control signal of the controller 300. At this point, the cool water and the hot water are simultaneously supplied.
• the primary water supply is finished. Also, when the primary water supply finishes, the supply of the cool water stops and only the hot water is supplied up to the set water level according to detection of water amount. Sub ⁇ sequently, when the detected water temperature does not reach a temperature set by the above-selected course after the water supply up to the set water level finishes, the heater 600 is operated so that the washing water may reach the relevant water temperature.
• the motor 700 is controlled to operate simultaneously so that the pulsator (not shown) may perform an agitation motion simultaneously with the operation of the heater 600.
• two-step water supply is preformed such that the primary water supply increases a detergent density with a small amount of water to remove a primary pollution and the secondary water supply supplies only the hot water to reduce a time for which the heater 600 operates. Since only the hot water is supplied during the secondary water supply, a time required for the temperature of the washing water to reach a set temperature is shortened. Also, since the washing water is supplied over a multi-step as described above, power consumption reduces. Also, it is possible to improve washing efficiency by operating the motor 700 while the heater 600 operates.
