After repeating the washing process is terminated.

그리고, 세탁기의 급수용물은 대부분 급수호스를 수도꼭지와 연결하여 수돗물을 사용한다. 한편, 이러한 급수과정에서 물의 낭비를 방지하도록, 욕조물 펌프(11)를 사용하여 욕조물을 급수하여 세탁기에 공급하기도 한다. 이러한, 욕조물 급수과정은 다음과 같다.In addition, most of the water for the washing machine uses tap water by connecting the water supply hose to the faucet. On the other hand, in order to prevent waste of water in this water supply process, the tub water may be supplied to the washing machine by using the tub water pump 11. This, bath water supply process is as follows.

사용자가 욕조물펌프(11)을 온시키고, 욕조물기능키을 선택하면, 마이컴(10)의 제어에 의해 급수밸브(8)가 동작하여 수도물의 급수를 차단하게 되고, 욕조물이 세탁기에 급수된다.When the user turns on the bath water pump 11 and selects the bath water function key, the water supply valve 8 operates under the control of the microcomputer 10 to block water supply of tap water, and the bath water is supplied to the washing machine. .

계속하여 욕조물의 급수가 행하여지면 수위센서(12)의 신호를 받아 급수완료인가를 마이컴은 판단한다. 급수가 완료된 것으로 판단되면, 부저구동부(17)를 동작하여 급수완료경고음을 발생하고 세탁을 진행한다.Subsequently, when water is supplied to the bath water, the microcomputer determines whether water supply is completed by receiving a signal from the water level sensor 12. When it is determined that the water supply is completed, the buzzer driving unit 17 is operated to generate a water supply completion warning sound and proceed with washing.

그런데, 이와 같이 급수완료경고 후에도 사용자가 욕조물펌프를 오프시키지 않으면 욕조물이 계속하여 급수되어 세탁수가 세탁조를 넘쳐흐르게 되는 문제점이 있었다.However, even after the water supply completion warning, if the user does not turn off the tub water pump, the tub water continues to be watered, and the wash water overflows the washing tank.

본 발명은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 세탁조에 공급되는 욕조물이 일수감지수위까지 계속 급수되면, 세탁행정을 중지하여 세탁수가 세탁조를 넘쳐흐르는 것을 방지할 수 있는 세탁기의 욕조물 급수 제어방법의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art, when the tub water supplied to the washing tank is continuously supplied to the water level, the washing water stops the washing administration to prevent the washing water from overflowing the washing tank To provide a control method.

사용자가 세탁물을 투입한 상태에서 전원을 공급하여 시작키를 누르게 되면 마이콤(10)은 세탁모터(5)을 좌, 우로 반전 구동시켜 포량감지부(19)를 통해 포량을 감지한 후 그 감지된 포량에 대응되는 수위를 설정한다. 이어서, 욕조물펌프(11)을 온하고, 욕조물급수기능을 선택하면, 수돗물과 연결된 급수밸브(8)을 턴오프하고, 욕조물 급수를 행한다.When the user presses the start key by supplying power in the state where laundry is put in, the microcomputer 10 reversely drives the washing motor 5 to the left and right to detect the quantity through the quantity detecting unit 19 and then detects the quantity. Set the water level corresponding to the dose. Subsequently, when the bathtub water pump 11 is turned on and the bathtub water supply function is selected, the water supply valve 8 connected to the tap water is turned off, and the bathtub water supply is performed.

설정된 급수수위까지 급수가 완료되면, 수위센서(12)의 신호를 받아 마이컴(10)은 급수완료 부저음을 울리어 사용자로 하여금 욕조물의 급수를 중단하도록 하고 세탁모터(5)를 구동시켜 세탁날개(4)를 좌, 우로 일정주기를 갖고 회전시키어 세탁행정을 진행한다.Upon completion of water supply to the set water level, the microcomputer 10 receives a signal from the water level sensor 12 and sounds the water completion buzzer so that the user stops the water supply of the bath water and drives the washing motor 5 to wash the blade. 4) Rotate left and right with a certain period to proceed with the laundry administration.

한편, 급수가 완료되어, 급수완료 부저음을 울리었으나, 욕조물의 급수가 중단되지 않고 계속 급수가 이루어지면, 이상경보를 발하여 사용자로 하여금 급수를 중단하도록 한다.On the other hand, when the water supply is completed, and the water supply completion buzzer sounds, but the water supply of the bath water is not interrupted and the water is continuously supplied, an alarm is issued to allow the user to stop the water supply.

계속하여, 이상경보를 발하였으나, 급수가 중단되지 않고 계속하여 이루어져서 일수감지수위에 달하면, 수위센서(12)의 감지신호를 받은 마이컴(10)의 제어신호에 따라 일정시간 세탁모터(5)의 구동을 중지한다.Then, when the abnormal alarm is issued, but the water supply is made continuously without reaching the day to reach the day detection level, according to the control signal of the microcomputer 10 received the detection signal of the water level sensor 12 of the washing motor 5 Stop the drive.

이어서, 세탁행정중에는 급수면이 상하로 변동하므로 세탁모터의 중지에 따라 급수면의 상하변동이 없어진 상태에서 급수면이 일수감지수위(a)에 달하였는가를 다시 판단한다.Subsequently, since the water supply surface fluctuates up and down during the washing operation, it is again determined whether the water supply surface reaches the water detection level (a) while the water supply surface is not changed up and down according to the stoppage of the washing motor.

재 판단결과, 급수면이 일수감지수위(a)에 미달한 경우에는 세탁모터(5)를 재기 동하여 세탁을 진행하여 상기 과정을 반복한다.As a result of the re-determination, when the water supply surface is below the water detection level (a), the washing motor 5 is restarted to proceed with the washing and the above process is repeated.

재 판단결과, 급수면이 일수감지수위에 도달한 경우에는 세탁수가 세탁조를 넘쳐흐르는 것을 방지할 수 있도록 세탁행정을 중단하고, 이상알림메시지를 표시한다.As a result of the re-evaluation, when the water surface reaches the water detection level, the washing administration is stopped to prevent the washing water from overflowing the washing tank, and an abnormality notification message is displayed.

이상, 설명한 바와 같이, 본 발명에 따르면, 세탁조에 공급되는 욕조물이 일수감지수위까지 계속 급수되면, 세탁행정을 중지하여 세탁수가 세탁조를 넘쳐흐르는 것을 방지할 수 있다.As described above, according to the present invention, when the tub water supplied to the washing tank is continuously supplied to the water detection level, the washing operation can be stopped to prevent the washing water from overflowing the washing tank.
