세탁기의 언발란스감지방법How to detect unbalance of washing machine

본 발명은 세탁기의 언발란스 감지방법에 관한 것으로, 특히 세탁이나 헹굼완료후 탈수시 혹은 일련의 세탁행정중 탈수운전시 세탁물의 꼬임에 의한 세탁조의 언발란스를 안전스위치로 감지함에 있어서, 상기 안전스위치의 온,오프시간으로 언발란스를 신속하게 감지할 수 있도록 한 세탁기의 언발란스 감지방법에 관한 것이다.The present invention relates to a method for detecting an unbalance of a washing machine. In particular, in the dehydration after washing or rinsing, or during the dehydration operation during a series of washing operations, the safety switch detects an unbalance of a washing tank caused by twisting of a laundry. The present invention relates to a method for detecting an unbalance of a washing machine, which enables to quickly detect an unbalance with an off time.

일반적으로 세탁기의 언발란스감지는 세탁기의 저수조 외측 상단에 장착되는 안전스위치에 작동 횟수로 감지하도록 되었다. 즉 상기 안전스위치의 언발란스 감지는 일련의 세탁행정에서 배수후 발란스탈수시 세탁조를 소정의 시간(4초온,3초오프)동안 4 회정도로 실시하여 상기 첫 번째(7초) 안전스위치의 작동을 감지하고 이어서 두 번째 (7초)동안 상기 안전스위치의 작동유무를 감지하여 이 감지된 안전스위치의 작동횟수로 언발란스를 감지하도록 되어 있어 상기 언발란스를 감지하려면 적어도 4 초동안 모터를 구동하고 이어서 다음 안전스위치의 작동시간까지 7초간을In general, the unbalance detection of the washing machine was detected by the number of operations in the safety switch mounted on the outer top of the water tank of the washing machine. That is, the unbalance detection of the safety switch detects the operation of the first (7 seconds) safety switch by performing the washing tank four times for a predetermined time (4 seconds on, 3 seconds off) when the balance is dewatered after draining in a series of washing strokes. And then detect the presence or absence of the safety switch for the second (7 seconds) and detect the unbalance by the number of operation of the detected safety switch. To detect the unbalance, drive the motor for at least 4 seconds and then the next safety switch. 7 seconds until

기다려야만 언발란스를 감지하도록 되어 있다.You must wait to detect unbalance.

이와같이 종래에는 탈수시 언발란스를 발란스탈수행정에서 안전스위치의 작동상태 즉 저수조가 안전스위치를 치는 것으로 언발란스를 감지하고 판단하도록 되어 있어 상기 세탁물의 꼬임이 심하게 발생되어 언발란스가 크게 생기게 되는 경우 상기 언발란스를 감지하는 시간이 길게 되어 전체적인 탈수시간이 길어질 뿐만 아니라, 그 만큼 소음이 크게 발생되고, 또한 저수조와 안전스위치의 부딪침에 의한 저수조의 외상을 손상시키고, 심한 경우에는 세탁기의 흔들림에 의한 이동을 시키게 되어 더욱 더 언발란스를 가중시키게 되는 문제점을 가지게 되었다.As described above, in the prior art, when the dehydration is performed, the unbalance is detected and judged as the operating state of the safety switch, that is, the water tank, by pressing the safety switch in the balance dewatering stroke.
