Abstract

본 발명은 드럼 세탁기의 수위감지방법에 관한 것으로써, 특히 드럼 세탁기의 정확한 수위감지로 세탁수의 소비를 줄이고, 세탁효과를 최대화할 수 있도록 한 드럼 세탁기의 수위감지방법에 관한 것이다.The present invention relates to a water level sensing method of a drum washing machine, and more particularly, to a water level sensing method of a drum washing machine to reduce the consumption of washing water and maximize the washing effect by the accurate level detection of the drum washing machine.

상기와 같은 본 발명의 드럼 세탁기의 수위감지방법은 사용자가 드럼세탁기의 세탁행정 스위치를 온시키면 세탁기의 드럼내에 세탁 수의 급수가 실시되고, 상기 세탁수의 급수가 실시됨과 동시에 수위센서에서 수위센싱을 하며, 상기 세탁구의 수위센싱이 되면 세탁기의 세탁수가 설정된 수위에 도달하였는지를 비교판단하는 제1스텝과: 상기 제1스템에서 드럼 세탁기의 세탁수가 설정된 수위에 도달하였다면 세탁행정이 실시되고, 세탁행정이 완료되었는지를 비교 판단하는 제2스텝과: 상기 제2스텝에서 세탁행정이 완료 되었다면 드럼세탁기의 다음 행정을 진행하는 제3스텝과: 상기 제2스텝에서 세탁행정이 완료되지 않았을 경우 마이콤에서 모터의 온/오프상태를 판단하는 제4스텝과; 상기 제4스텝에서 모터가 온상태일 경우에는 계속적으로 세탁행정을 실시하는 제5스텝과; 상기 제4스텝에서 모터가 오프상태일 경우 상기 오프된 상태에서 소정의 시간의 경과 여부를 판단하는 제6스텝과; 상기 제6스텝에서 모터의 오프상태에서 소정 시간이 경과되어 드럼 세탁기내의 드럼이 무진동상태가 되면 다시 드럼내의 세탁수 수위를 센싱하도록 한 제7스텝과, 상기 제6스텝에서 모터의 오프상태에서 소정시간이 경과되지 않았을 경우 다시 계속적으로 세탁행정이 실시되도록 한 제8스텝으로 이루어져 드럼내의 수위를 보다 정확하게 감지할 수 있어 세탁수의 소비를 최대한으로 줄이고, 세탁효과를 향상시킬 수 있도록 한 것이다.In the water level detecting method of the drum washing machine of the present invention as described above, when the user turns on the washing stroke switch of the drum washing machine, the water supply of the washing water is performed in the drum of the washing machine, the water supply of the washing water is performed, and the water level sensing is performed at the water level sensor. When the water level of the washing machine is sensed, the first step of comparing whether the washing water of the washing machine has reached the set level: and if the washing water of the drum washing machine at the first system reaches the set water level, the washing administration is performed, the washing administration A second step for comparing and determining whether the washing operation has been completed; and a third step for carrying out the next stroke of the drum washing machine if the washing operation is completed in the second step; and if the washing operation is not completed in the second step, the motor Determining a on / off state of the fourth step; A fifth step of continuously washing the laundry when the motor is turned on in the fourth step; A sixth step of determining whether a predetermined time has elapsed in the off state when the motor is in the off state in the fourth step; If the drum in the drum washing machine is in a non-vibration state after a predetermined time has elapsed in the off state of the motor in the sixth step, the seventh step of sensing the washing water level in the drum again, and in the sixth step, When the time has not elapsed, the eighth step is to continue the washing administration again to more accurately detect the water level in the drum to reduce the consumption of the wash water to the maximum, and to improve the washing effect.
