Abstract

본 발명은 전자동 세탁기의 수위 조절기능 및 회로에 관한 것으로 특히 세탁기의 자동수위 설정에 대한 사용자의 수동수위 조정성향을 마이콤이 학습하여 추후 세탁시 그 학습내용을 기초로 사용자의 세탁성향에 맞게 수위를 설정하도록 하여 최적의 세탁조건을 이루게 한 것이다.The present invention relates to the water level control function and the circuit of the automatic washing machine. In particular, the microcomputer learns the user's manual water level adjustment tendency for automatic water level setting of the washing machine, and the water level is adjusted according to the user's washing tendency based on the learning contents in the later washing. It is set to achieve the optimal washing condition.

종래의 세탁기 수위조절 장치는 세탁시에 마이콤이 자동적으로 포량센서 입력데이터와 미리 설정된 데이터를 비교하여 수위를 결정하므로 사용자의 기호에 맞지 않을 경우는 소비자가 매번 세탁시마다 수위를 다시 수동입력 시켜서 사용하여야 하고 포량감지에 관련하여 펄스갯수에 영향을 주는 V벨트의 장력, 포토 트랜지스터의 증폭도 등의여러가지 변수에 따라 감지오차를 갖게되므로 정확도가 저하되는 문제점들이 있었다.In the conventional washing machine water level adjusting device, the microcomputer automatically compares the quantity sensor input data and the preset data during washing to determine the water level. Therefore, when the washing machine does not meet the user's preference, the consumer must manually input the water level again every time the washing is performed. In addition, the accuracy of the V-belt tension affecting the number of pulses and the amplification degree of the phototransistor has a detection error according to various variables.

본 발명은 이에 마이콤(10′)과 통신 가능하도록 한E²PROM(11;Electrically Erasable Programmable Read Only Memory)을 구비시켜 자동수위 조절 세탁기 E²PROM에 저장된 데이터를 기초로 사용자의 수위설정 성향을 학습하게 함으로써 차기 세탁기 그것을 기초로 수위조절 할 수 있도록 구성한다.The present invention is equipped with an E ² PROM (Electrically Erasable Programmable Read Only Memory) 11 to enable communication with the microcomputer 10 'to learn the user's level setting tendency based on the data stored in the automatic water level washing machine E ² PROM. By doing so, the next washing machine is configured to adjust the water level on the basis of it.
