Abstract

본 발명은 세탁완료후 배수시 배수펌프로 감제 배수를 하게 되는 세탁기에 있어서, 배수펌프에 흐르는 전류 및 배수수위 상태로 배수이상 상태를 감지할 수 있도록 한 세탁기의 배수이상감지방법에 관한 것으로, 본 발명은 세탁완료후 배수시 배수펌프를 구동시켜 배수운전을 시작하고, 배수펌프에 흐르는 전류를 감지하는 단계와, 상기 단계에서 배수펌프의 전류가 소정의 구동전류 규정치 이상인가를 판단하는 단계와, 상기 단계에서 배수펌프의 전류가 규정치 이상이 아니면, 배수를 계속하면서 수위센서로 수위 변화 유무를 판단하는 단계와, 상기 단계에서 수위센서의 수위변화가 있으면 배수완료를 판단하면서 배수가 완료될때까지 배수를 진행하고, 상기 수위센서의 수위변화가 없으면 배수펌프를 정지하여 배수를 정지하는 단계로 이루어짐을 특징으로 한다.The present invention relates to a method for detecting a drainage abnormality of a washing machine in which a drainage condition is detected by a drainage pump when the drainage is completed after washing is completed. The present invention is to start the drainage operation by driving the drainage pump at the time of drainage after the completion of washing, detecting the current flowing in the drainage pump, and in the step of determining whether the current of the drainage pump is more than a predetermined drive current prescribed value; If the current of the drain pump in the above step is not more than the prescribed value, the step of determining the water level change with the water level sensor while continuing to drain, and if there is a water level change of the water level sensor in the step, draining until the drainage is completed while determining the drainage completion Proceeding to the step of stopping the drainage by stopping the drainage pump if there is no water level change of the water level sensor It features.

Description

How to detect drainage abnormalities in the washing machine

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제2도는 본 발명 세탁기의 배수이상감지방법에 대한 플로우챠트.2 is a flow chart of the drainage abnormality detection method of the washing machine of the present invention.

Claims

In the drainage by driving the drainage pump after the completion of the washing operation, the drainage abnormality detection method of the washing machine characterized in that it is possible to detect the abnormality of the drainage by the change in the drainage level detected by the current flowing in the drainage pump and the water level sensor during the drainage. .

The method of claim 1, further comprising: starting a drainage operation by driving the drainage pump at the time of drainage, detecting a current flowing into the drainage pump, and determining whether the current of the drainage pump is equal to or greater than a predetermined driving current prescribed value at the step. In the step, if the current of the drain pump in the step is not more than the prescribed value, continue to drain the water level sensor to determine whether there is a water level change, and if there is a water level change of the water level sensor in this step, drainage is completed while determining the completion of the water level The drainage progress detection method of the washing machine characterized in that the step of stopping the drainage by stopping the drainage pump if there is no water level change of the water level sensor.
