세탁기의 탈수방법How to dehydrate the washing machine

본 발명은 세탁기의 탈수방법에 관한 것으로, 특히 세탁이나 헹굼완료후 탈수시 배수펌프를 구동시켜 강제배수하는 세탁기에 있어서, 상기 탈수시에는 배수펌프를 소정의 시간간격으로 온,오프하면서 배수하고 탈수하도록 함으로써, 탈수시 배수펌프의 구동에 의한 소음감소는 물론 탈수효과도 크게 향상할 수 있도록 한 세탁기의 탈수방법에 관한 것이다.The present invention relates to a washing machine dewatering method, in particular a washing machine for driving the drainage by driving the drainage pump during dehydration after washing or rinsing completion, during the dehydration while draining the drainage pump on and off at a predetermined time interval and dewatering By doing so, it relates to a dehydration method of the washing machine to be able to greatly improve the dehydration effect as well as the noise reduction by driving the drainage pump during dehydration.

일반적으로 세탁기는 세탁이나 헹굼완료 후 배수 및 탈수시 단순히 배수밸브를 열어 세탁수를 배수하는 것이 있는가 하면, 배수펌프를 구동시켜 강제로 세탁수를 배수하는 것이 있는바, 상기 전자의 경우 배수 및 탈수시 단순히 배수밸브를 열어 세탁수를 자연배수하도록 되어 있어 구동소음이 발생되지 않으나, 상기 후자의 경우에는 배수 및 탈수시 배수펌프를 구동하면서 배수하고 탈수하도록 되어 있어 상기 배수완료 후 탈수시 초기에는 회전원심력에 의하여 세탁물로부터 세탁수가 발생되지만 소정의 탈수시간이 경과하면 세탁물로부터 분리되는 세탁수가 없게 되어 상기 탈수시 배수펌프의 구동을 초기에 소정의 시간동안만 구동하여 배수하고 소정의 시간이 경과하면 배수할 필요가 없음에도 불구하고 탈수가 완료되는 시점까지 계속해서 배수펌프를 구동하도록 되어 있어 상기 배수펌프의 불필요한 구동으로 인한 전력낭비는 물론 공회전을 야기시키게 되어 탈수시 발생된 세탁수를 용이하게 배수하지 못하게 되어 탈수효과를 저하시키고 뿐만 아니라 상기 배수펌프의 구동 소음까지 더하여 주게 되므로 세탁기 전체의 구동 소음이 크게 발생시키게 되는 문제점을 가지게 되었다.In general, a washing machine may drain water by simply opening a drain valve when draining and dehydrating water after washing or rinsing, or driving water may be forcibly drained by driving a drain pump. In the latter case, the driving noise is not generated by simply opening the drain valve to drain the washing water, but in the latter case, the drainage and dehydration are driven while driving the drainage pump during drainage and dehydration. Washing water is generated from the laundry by centrifugal force, but when a predetermined dehydration time has elapsed, there is no washing water separated from the laundry. When the dehydration is performed, the drainage pump is initially driven only for a predetermined time and then drained. Continue to ship until dehydration is complete, even though it is not necessary It is designed to drive the pump, not only the waste of power due to unnecessary driving of the drainage pump, but also cause idling, so that it is not easy to drain the washing water generated during dehydration, which lowers the dehydration effect and also the driving noise of the drainage pump. In addition, the driving noise of the entire washing machine is greatly generated.

본 발명은 세탁이나 헹굼완료 후 배수 및 탈수시 배수펌프를 구동하면서 세탁수를 강제 배수하고 탈수하는 세탁기의 탈수방법에 있어서, 상기 탈수시 세탁수를 펌핑하여 배수하는 배수펌프의 구동소음을 줄이고 탈수효과도 향상하기 위하여, 세탁이나 헹굼완료후 배수펌프를 구동하면서 배수하고 배수완료시 배수펌프를 정지하며 상기 배수완료후 모터를 고속회전시키면서 탈수하고 상기 배수펌프를 구동시키면서 배수할때, 상기 배수펌프를 소정의 시간간격으로 온,오프하면서 배수하고 탈수완료하도록 한 것을 특징으로 한다.The present invention is a dewatering method of a washing machine for forcibly draining and dewatering the washing water while driving the drainage pump during the drainage and dehydration after washing or rinsing completion, reducing the driving noise of the drainage pump for pumping and draining the wash water during dehydration In order to improve the effect, after draining the washing and rinsing completion of driving the drain pump and stops the drainage pump when the drainage is completed, the drainage while draining while rotating the motor at high speed after the completion of drainage and driving the drainage pump, It is characterized in that the drained on and off at a predetermined time interval and the dehydration is completed.

상기와 같이 이루어지는 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention made as described above are as follows.

먼저 세탁기에 전원을 인가하고 세탁하고자 하는 세탁물을 넣은 상태에서 운전신호입력부(가)를 통해서 운전하고자 하는 일련의 세탁행정을 설정하여 마이콤(나)에 입력하게 되면 상기 마이콤(나)에서는 기설정된 소정의 프로그램에 의하여 상기 운전신호입력부(가)에서 입력된 운전신호를 기설정된 소정의 프로그램에 의하여 제어하고 이 제어된 신호를 각 구동부에 출력하여 세탁을 하게 되는데 즉 상기 마이콤(나)에서는 기설정된 소정의 프로그램에 의하여 세탁하고자 하는 세탁량에 대한 수위를 결정하고, 수위가 결정되면 급수구동부(다)를 제어하여 세탁조에 결정된 수위로 급수를 하되, 급수되는 수위는 수위감지부(라)를 통해서 감지하면서 급수하고 상기 급수가 완료되면, 상기 마이콤(나)에서는 모터구동부(마)를 제어하여 세탁모터를 정,역회전시키면서 세탁을 진행하게 된다.First, when the power is supplied to the washing machine and the laundry to be washed is put in, the driving signal input unit sets a series of washing strokes to be operated and inputs them to the microcomputer (B). The driving signal inputted by the driving signal input unit (A) is controlled by a predetermined program according to a program of the control unit and outputs the controlled signal to each driving unit for washing. Determination of the water level for the amount of laundry to be washed by the program of, and if the water level is determined to control the water supply unit (C) to supply water to the determined water level in the washing tank, while the water level is detected through the water level detection unit (D) When the water supply is completed and the water supply is completed, the microcomputer (b) controls the motor driving part (e) to forward and reverse the washing motor. All while washing is in progress.

이와 같이 상기 세탁모터를 정역회전시키면서 세탁을 진행하고 있는 상태에서 세탁완료판단단계(20)로 가서 진행중인 세탁이 완료되었는가를 판단하게 되고, 이때 판단결과 세탁이 완료되지 않았으면 세탁이 완료될때까지 세탁을 진행하고, 상기 세탁이 완료되었으면, 세탁시 발생된 오염된 세탁수를 배수하기 위하여 배수단계(21)로 가서 배수펌프구동부(바)를 제어하여 배수펌프로 세탁수를 펌핑하면서 배수하고 이어서 배수완료판단단계(22)로 가서 배수가 완료되었는가를 판단하여 배수가 완료되지 않았으면 배수가 완료될때까지 배수펌프를 구동하면서 세탁수를 강제배하게 된다.As described above, the washing motor goes to the washing completion judging step 20 while the washing motor is in reverse rotation to determine whether the washing is in progress. If the washing is not completed, the washing is completed until the washing is completed. After the washing is completed, go to the drainage step 21 to control the drainage pump driving unit (bar) to drain the contaminated washing water generated during the washing and pumping the washing water with the drainage pump and then draining If the drainage is not completed by going to the completion judgment step 22 and the drainage is not completed, the washing water is forcibly drained while driving the drainage pump until the drainage is completed.

한편 상기 배수완료판단단계(22)에서 배수가 완료되었으면 상기 마이콤(나)에서는 배수펌프정지단계(23)로가서 배수펌프구동부(바)를 제어하여 배수펌프를 정지하고 배수후 세탁물에 스며들어 있는 세탁수를 짜주기 위하여 탈수단계(24)로 가서 모터구동부(마)를 제어하여 세탁모터를 고속회전시키면서 탈수를 진행하게 된다.On the other hand, if the drainage is completed in the drainage determination step 22, the microcomputer (b) goes to the drainage pump stop step 23 to control the drainage pump drive (bar) to stop the drainage pump and drained into the laundry after drainage In order to squeeze the washing water, go to the dehydration step 24 to control the motor driving part (e) to proceed with dehydration while rotating the washing motor at high speed.

이와 같이 상기 탈수를 진행하고 있는 상태에서, 상기 마이콤(나)에서는 탈수중이에 회전중심력에 의하여 세탁물로부터 분리되는 세탁수를 배수하기 위하여 배수단계(25)로 가서 탈수시 발생된 세탁수를 배수하기 위하여 위하여 배수펌프구동부(바)를 제어하여 배수펌프를 구동하되, 배수펌프를 소정의 시간 즉 5초 온하여 탈수시 발생되어 있는 세탁수를 펌핑하면서 배수한 후 10초 오프하여 탈수시 발생된 세탁수를 모았다가 상기 10초 오프가 경과되면 다시 배수펌프를 5초 온하여 모여진 세탁수를 배수하고 10초 오프하여 배수를 정지하는 일련의 반복되는 과정으로 배수하고 탈수를 진행하다가 이어서 탈수완료판단단계(26)로 가서 탈수가 완료되었는가를 판단하게 되고, 이때 판단결과 탈수가 완료되지 않았으면, 상기 탈수단계(24)로 가서 탈수 및 배수를 배수펌프를 소정의 시간간격으로 구동하면서 탈수가 완료될때까지 배수 및 탈수를 진행하고, 이어서 상기 탈수가 완료되었으면 모터구동부(마)를 제어하여 탈수를 중지하고 다음행정인 헹굼행정을 진행하되, 이때도 상기 세탁시와 마찬가지로 급수하고 세탁모터를 정,역회전시키면서 헹굼하고 배수하며, 상기 배수 완료 후 탈수시 상기 과정으로 반복하면서 배수하고 탈수를 하게 되는 것이다.As described above, while the dehydration is in progress, the microcomputer (b) goes to the drainage step 25 to drain the wash water separated from the laundry by the rotational center force during the dehydration, and drains the wash water generated during dehydration. In order to control the drainage pump driving part (bar) to drive the drainage pump, the drainage pump is turned on for a predetermined time, that is, 5 seconds while draining while pumping the wash water generated during dehydration after 10 seconds off to generate After collecting the wash water and the 10 seconds off, the drain pump is turned on again for 5 seconds to drain the collected wash water and then drained in a series of repeated processes to stop the drainage by turning off the water for 10 seconds and proceed with dehydration. In step 26, it is determined whether dehydration is completed. At this time, if the dehydration is not completed, go to the dehydration step 24 and dehydration and drainage. While driving the drainage pump at a predetermined time interval, draining and dehydration proceeds until dehydration is completed, and after the dehydration is completed, the motor driving part (e) is controlled to stop dehydration and proceed with the next rinsing stroke, In this case, as in the washing, the water is rinsed and drained while the washing motor is rotated forward and backward, and after the completion of the draining, the draining and the dehydration are repeated while repeating the above process.

이상에서 설명한 바와 같이 본 발명은 세탁이나 헹굼완료 후 배수펌프를 구동하여 강제로 배수하고, 이어서 탈수할때 배수펌프를 구동하면서 탈수시에 발생된 세탁수를 배수하되 세탁물로부터 분리되는 세탁수에 대하여 소정의 시간 간격으로 배수펌프를 온,오프 구동하면서 탈수시 발생된 세탁수를 모아가면서 배수하고 탈수하도록 함으로써, 상기 탈수시 배수펌프의 소정의 시간 간격에 의한 구동으로 불필요한 전력낭비 및 구동소음을 최대한 줄일 수 있고, 또한 탈수시 발생된 세탁수를 모아가면서 배수하게 되므로 탈수효과도 향상할 수 있으며, 나아가서는 세탁기의 전체 신뢰성을 크게 향상시킬 수 있는 효과를 제공하게 되는 것이다.As described above, the present invention forcibly drains by driving a drain pump after washing or rinsing completion, and then drains the wash water generated at the time of dehydration while driving the drain pump when dewatering. By driving the drain pump on and off at predetermined time intervals, the washing water generated during dehydration is collected and drained and dehydrated, thereby eliminating unnecessary power waste and driving noise by driving the drain pump at a predetermined time interval. It is possible to reduce, and also to drain while collecting the washing water generated during dehydration can improve the dehydration effect, and to provide an effect that can greatly improve the overall reliability of the washing machine.
