Abstract

본 발명은 세탁기의 불균형 감지장치 및 방법에 관한 것으로서, 특히 세탁기의 설치 및 탈수시 세탁물의 치우침을 감지할 수 있도록 한 세탁기의 불균형 감지장치 및 방법에 관한 것이다.The present invention relates to an apparatus and a method for detecting an imbalance of a washing machine, and more particularly, to an apparatus and a method for detecting an imbalance of a washing machine to detect a bias of laundry upon installation and dehydration of the washing machine.

세탁기의 불균형 감지방법은 세탁기의 탈수중 세탁물의 치우침에 의하여 탈수조가 불균형 감지레버에 닿게되는 소정 시간(t)을 측정한 후 상기 탈수조가 불균형 감지장치의 불균형 감지레버에 닿게되는 소정 시간이 66ms미만이면 탈수조의 정상동작을 실시하는 제1단계와, 상기 탈수조가 불균형 감지레버에 닿게되는 소정 시간이 66ms 이상 166ms 이하이면 세탁조의 불균형을 감지하여 불균형 감지 카운트를 1 증가한 후, 불휘발성 기억소자에 저장하는 제2단계와, 상기 제2단계에서 불휘발성 기억소자에 저장된 불균형 감지 카운트가 소정 설정치이상 인가를 판단한 후 상기 불휘발성 기억소자에 저장된 불균형 감지 카운트가 소정 설정치 이상이면 입력버튼부 및 동작 표시부에 세탁기 수평을 맞춰어 주세요 라는 신호가 나타나도록 하는 제3단계와, 상기 제3단계에서 불휘발성 기억소자에 저장된 불균형 감지 카운트가 4회 미만이면 재급수하고, 세탁날개를 회전시켜 세탁물을 고르게 한 후 배수 및 탈수를 실시하는 제4단계와, 상기 제2단계에서 탈수조 불균형 감지레버에 닿게 되는 소정 시간이 166ms 이상 500ms 이하이면 세탁기의 뚜껑이 열린 것으로 판단하여 탈수를 일시 정지 시키고 경보음을 제5단계와, 상기 제5단계에서 탈수조가 불균형 감지레베에 닿게되는 소정 시간(t)이 500ms 보다 작으면 정상 동작을 실시한 후 종료하는 제6단계를 포함하여 이루어진다.The imbalance detection method of the washing machine measures a predetermined time (t) at which the dehydration tank contacts the imbalance detection lever due to the skew of laundry during dehydration of the washing machine, and then the predetermined time for the dehydration tank to reach the imbalance detection lever of the imbalance detection device is less than 66 ms. In the first step of performing the normal operation of the dehydration tank, and if the predetermined time for which the dehydration tank is in contact with the imbalance detection lever is 66 ms or more and 166 ms or less, the imbalance of the washing tank is detected and the imbalance detection count is increased by one, and stored in the nonvolatile memory. And determining that the imbalance detection count stored in the nonvolatile memory device is greater than or equal to a predetermined value after determining that the imbalance detection count stored in the nonvolatile memory device is greater than or equal to a predetermined setting value. The third step to display the signal leveling the washing machine, and the In step 3, if the imbalance detection count stored in the nonvolatile memory device is less than 4 times, the water supply is re-supplied, the washing blade is rotated to even the laundry, and the drainage and dehydration are performed. When the predetermined time to reach the detection lever is 166ms or more and 500ms or less, it is determined that the lid of the washing machine is opened, and the dehydration is paused and the alarm sounds in the fifth step and the predetermined time for the dehydration tank to reach the imbalance detection lever in the fifth step ( If t) is less than 500 ms, a sixth step of terminating the normal operation is performed.

Claims

A washing machine having an imbalance detecting device, the imbalance detecting device of a washing machine comprising a nonvolatile memory device for storing the number of times the dehydration tank of the washing machine touches the imbalance detecting device.

When the dehydration tank reaches the imbalance detection lever due to the deflection of the laundry during dehydration of the washing machine, if the dehydration tank reaches the imbalance detection lever of the imbalance detection device, the dehydration tank may operate normally. A first step of performing, and a second step of detecting an imbalance of the washing tank by increasing the imbalance detection count by 1 if the predetermined time for which the dehydration tank contacts the imbalance detection lever is 66 ms or more and 166 ms or less, and then storing the imbalance detection count in a nonvolatile memory device; After determining that the imbalance detection count stored in the nonvolatile memory device is greater than or equal to the predetermined value in step 2, if the imbalance detection count stored in the nonvolatile memory device is greater than or equal to the predetermined setting value, adjust the washing machine to the input button unit and the operation display unit. And a non-volatile group in the third step. When the imbalance detection count stored in the deterrent is less than four times, the water supply is re-supplied, the washing step is rotated to even the laundry, and the drainage and dehydration are carried out, and in the second step, the dehydration tank contacts the imbalance detection lever If the predetermined time is 166 ms or more and 500 ms or less, it is determined that the lid of the washing machine is opened and the dehydration is paused and the alarm sounds in step 5 and the predetermined time (t) at which the dehydrating tank touches the imbalance detection lever in step 5 is greater than 500 ms. If it is small, the imbalance detection method of a washing machine comprising a sixth step of ending after performing a normal operation.
