Abstract

본 발명은 전자동 세탁기의 언발란스(Unbalance) 검출장치와 방법에 관한 것으로, 특히 탈수시 세탁물의 치우침으로 인한 세탁조의 치우침으로 인하여 발생되는 세탁조의 언발란스를 검출하여 탈수시 소음해소 및 세탁기 전체의 떨림현상을 해결하고자 한 것이다.The present invention relates to an unbalance detection apparatus and method of a full-automatic washing machine, and more particularly, to detect unbalance of a washing tank caused by the washing tank bias caused by the deflection of laundry during dehydration, thereby reducing noise and shaking of the whole washing machine. It was intended to solve.

종래 전자동 세탁기는 기계적 스위치(17)를 이용하므로 소음이 심하고, 적은포량에서 세탁물의 치우침을 검출하지 못하는 경우가 발생되여 탈수성능을 저하시키게 되며, 좌우 흔들림을 기계적으로 검출하기 때문에 세탁조(2, 3)가 좌우로 흔들리면서 스위치를 온, 오프하여야 하므로 검출속도가 늦은 문제점이 있었다.Since the conventional automatic washing machine uses the mechanical switch 17, the noise is severe, and when the washing of the laundry is not detected in a small quantity, the dehydration performance is reduced, and the washing tanks 2 and 3 are mechanically detected. ) Has to be switched on and off while shaking left and right, so the detection speed was slow.

본 발명은 이와같은 종래의 문제점을 해결하기 위하여 중량센서를 이용하여 세탁조의 기울어짐을 감지하여 탈수시 세탁조가 기울어짐으로 인하여 발생되는 세탁조의 언발란스를 검출하므로서 탈수시 소음해소 및 외조와의 충돌로 인한 세탁기 전체의 떨림현상을 방지할 수 있도록 한 것이다.The present invention detects the inclination of the washing tank by using a weight sensor to solve such a conventional problem by detecting the unbalance of the washing tank caused by the inclination of the washing tank when dewatering, due to noise cancellation and deterioration due to collision with the outer tank It is to prevent shaking of the whole washing machine.

Claims

A weight sensor 21 configured at a lower part of the washing machine to detect the weight of the laundry and the inclination of the washing tank and a sensor circuit unit for converting the displacement of the washing tank detected by the weight sensor 21 into an electrical signal; 22) and the microcomputer 23 for controlling the driving unit 24 by determining the inclination degree of the washing tank by receiving the electric signal output from the sensor circuit 20, and the washing motor under the control of the microcomputer 23. And a driving unit (24) for driving various water supply and drain valves.

After the washing is completed, the first step of reading the input frequency according to the displacement detected by the weight sensor 21 by starting the drainage by turning on the drain valve and draining, and the frequency read in the first step in the previous step The second process consists of stopping the dehydration and relieving the unbalance when the difference of frequency occurs more than a certain value compared to the read frequency, and proceeding to dehydration if the difference of frequency is within a certain value. Unbalance detection method of a full automatic washing machine, characterized in that.
