  • the washing machine rotates a rotating tub, and a pulsator by a driving force of a motor, for conducting washing, rinsing, and spinning, wherein laundry is washed by using friction between the laundry, the washing water, and the rotating tub occurred as washing water and the laundry introduced in the rotating tub are pulsated.
  • the related art washing machine conducts respective cycles automatically according to numbers of times, periods, and etc., of the washing, rinsing, and spinning, either selected, and set by a user directly, or preset by a manufacturer.
  • FIG. 1 illustrates a block diagram showing a system of a related art washing machine schematically
  • FIG. 2 illustrates a flow chart showing operation of the related art washing machine.
  • the related art washing machine is provided with a key application part 10 for selecting a user's desired function, a water level sensing part 20 for sensing a water level, a controlling part 30 for controlling cycles of the washing machine according to functions selected through the key application part 10, and controlling loads according to a result of water level sensed by the water level sensing part 20, a load driving part 40 for driving different loads, such as water supply valve, a drain valve, the motor, and the like, and a display part 50 for displaying operation states of the functions selected through the key application part 10 under the control of the controlling part 30.
  • the display part 50 has 88 segments for displaying a remained washing time period, and a plurality of light emission diodes LED.
  • the related art washing machine processes washing as the controlling part 30 applies control signals to the load driving part 40 according to a preset washing cycle sequence, to drive the motor (not shown), the water supply valve (not shown), the drain valve (not shown), and the like, in succession.
  • the controlling part 30 provides control signals so that particulars of the setting the user selects are displayed on the display part 50, when the display part 50 displays operation time periods, and remained washing time periods required for washing, rinsing, and spinning functions respectively for each of washing courses, in response to the control signals from the controlling part 30.
  • the drain valve Upon completion of the rinsing cycle, the drain valve is turned on (S18). Then, sensing of a zero water level at the water level sensing part is determined (S19). As a result of the determination (S 19), if the water level sensing part senses the zero water level, the drain valve is turned off; and a final spinning cycle is conducted (S20-S21).
  • the related art washing machine turns off the water supply valve to stop water supply upon completion of the water supply up to a water level meeting to an amount of laundry, starts the washing cycle, stops the motor (not shown) if the washing cycle is progressed as much as the preset time period, to end the washing cycle, and, on the same time, puts the drain valve (not shown) into operation, for draining the washing water.
  • the water level sensing part 20 senses the water level until the water level reaches to the zero water level when the washing machine starts the spinning. Then, the washing machine turns off the drain valve (not shown) when the preset set spinning time period is passed, and starts rinsing.
  • the water supply valve (not shown) is turned off, and the motor (not shown) is put into operation, to conduct the rinsing, when the controlling part 30 senses a rinsing time period to drive the drain valve (not shown) to drain the washing water if the preset set time period is passed.
  • the drain valve (not shown) is turned off, and the final spinning is conducted, to finish an entire washing process.
  • the related art washing machine can only display operation states, but not warning messages as the display part is of an LED type, damage to the laundry and re-washing may be caused from overlooking, that deteriorate a washing performance.
  • the present invention is directed to a method for displaying a warning message of a washing machine that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
  • An object of the present invention is to provide a method for displaying a warning message of a washing machine, in which warning messages required to pay attention are displayed upon a power is applied to the washing machine before the washing machine is put into operation, for preventing damage to laundry from various causes in advance.
  • the method for displaying a warning message of a washing machine having a water storage tub for storage of washing water, a drum rotatably fitted inside of the water storage tub, a motor for rotating the drum, a controlling part for controlling washing cycles, a microcomputer for controlling various loads and motor, and a display part for displaying progress of the washing cycles and particulars of control by the controlling part, includes the step of displaying pre-washing warning messages on the display part in characters or graphics according to kind of laundry, and washing water environment of use after a power is applied to the washing machine, for giving notice to the user.
  • the method further includes the step of handling laundry according to the pre-washing warning messages if laundry pertinent to the pre-washing warning messages displayed on the display part presents.
  • FIG. 3 illustrates a block diagram showing a system of a washing machine in accordance with a preferred embodiment of the present invention
  • FIG. 4 illustrates a flow chart showing the steps of a method for displaying a warning message of a washing machine in accordance with a preferred embodiment of the present invention.
  • the washing machine in accordance with a preferred embodiment of the present invention includes a PC 100, an interface 200 for data exchange with the PC 100, a key application part 300 for users selection of a desired washing course and application of operation commands for the desired washing course, a water level sensing part 400 for sensing a water level, a storage part 500 for storage of a washing machine operation algorithm and pre-washing warning messages, a liquid crystal display (LCD) 800 for displaying the pre-washing warning messages and a progress of relevant cycle, a controlling part 600 for reading the pre-washing warning message from the storage part and displaying on the LCD 800, and controlling data communication with an external device through the interface 20 according to a request from the user when a power is applied to the washing machine, and a load driving part 700 for controlling driving of required load in response to control signals from the controlling part 600.
  • a PC 100 the washing machine
  • a key application part 300 for users selection of a desired washing course and application of operation commands for the desired washing course
  • a water level sensing part 400 for sensing
  • the washing machine When a user presses a power key on the key application part 300, the washing machine reads the pre-washing warning messages from the storage part 500, and displays on the display part 800. Then, the user makes sure that pre-washing warnings are observed with reference to the pre-washing warning messages. Then, the user presses an operation button, to conduct a required washing cycle for a selected course.
