본 발명은 세탁기의 배수 펌프 진공방지방법에 관한 것으로, 특히 배수펌프로 배수를 하게 되는 세탁기에 있어서, 세탁 및 헹굼완료후 탈수시 계속 구동되는 배수펌프에 진공발생을 방지하면서 탈수를 할 수 있도록 한 세탁기의 배수펌프 진공방지방법에 관한 것이다.The present invention relates to a method for preventing a drain pump vacuum of a washing machine, and more particularly, in a washing machine that drains water with a drain pump, so that dehydration can be performed while preventing the occurrence of a vacuum in the drain pump that is continuously driven after dehydration after washing and rinsing is completed. It relates to a drain pump vacuum prevention method of the washing machine.

종래의 세탁기에서 배수펌프로 펌핑하여 세탁수를 배수할 때, 수위감지기에 의하여 세탁조내의 세탁수 유무를 판단하면서 펌핑하여 배수를 하도록 되어 있다.When draining the wash water by pumping with a drain pump in a conventional washing machine, the water level sensor is pumped to determine the presence or absence of the wash water in the washing tank to drain.

그러나 상기와 같이 펌핑작용으로 배수할 때 펌프의 계속해서 동작에 의하여 본 탈수시작 바로 전에 많은 공기의 유입되고, 이 유입된 공기는 탈수시작후 세탁물에서 나오는 물에 의하여 펌프에 남아있게 되어 이 남아있는 공기는 계속 구동하는 펌프의 흡입력에 의하여 공기가 빠져나가지 못하므로 인하여 펌핑작용이 정상적으로 이루어지지 않을 뿐만 아니라, 심한 경우에는 펌핑작용하지 못하게 되어 정상적인 배수를 하지 못하게 된다.However, when draining by the pumping action as described above, a large amount of air is introduced just before the start of dehydration by the continuous operation of the pump, and this inlet air remains in the pump by the water from the laundry after the start of dehydration. The air is not pumped out due to the suction force of the pump which continues to be driven, and thus the pumping action is not normally performed, and in severe cases, the pumping action is prevented, thus preventing normal drainage.

그러므로 상기 펌프 작동시 발생되는 펌프 후방의 진공상태를 제거하기 위하여 별도의 배기호스를 형성하여 상기 펌핑시 발생되는 진공상태 발생을 억제하거나, 혹은 여러 가지 형태로 설계를 변경하여도 펌핑작용에 의하여 발생되는 진공상태를 제거하도록 하였으나, 상기 근본적으로 상기 진공상태를 제거하지 못하는 문제점을 가지고 있다.Therefore, a separate exhaust hose is formed in order to remove the vacuum state at the back of the pump generated during the operation of the pump, thereby suppressing the occurrence of the vacuum state generated at the time of pumping, or even by changing the design in various forms. Although the vacuum state is removed, there is a problem in that the vacuum state cannot be removed.

따라서 본 발명의 목적은 세탁 및 헹굼완료 후 탈수시 배수하기 위하여 구동하는 배수펌프를 제어하여 펌프에 진공발생을 방지하도록 하고자 하는데 있다.Therefore, an object of the present invention is to prevent the occurrence of vacuum in the pump by controlling the drain pump to drive to drain when dehydration after washing and rinsing completion.

상기의 목적을 실현하기 위하여 본 발명은 일련의 세탁행정에서 세탁 및 헹굼완료후 탈수시 발란스탈수완료후 소정의 시간 간격으로 소정의 횟수 배수펌프를 온,오프 펌핑하면서 탈수를 하도록 이루어짐을 특징으로 한다.In order to realize the above object, the present invention is characterized in that the dehydration after washing and rinsing in a series of washing strokes is made to dehydrate while pumping a predetermined number of drain pumps on and off at predetermined time intervals after the completion of balancing dehydration. .

이하 첨부된 도면에 의거 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
