Drain through 9) to dehydrate.

이후 상기 세탁수위와 동일한 재급수를 행하고, 세탁모터(5)를 재기동시키어 세탁날개(4)을 좌, 우로 반전시키어 헹굼행정을 진행하고, 헹굼행정이 완료되면 상기와 같이 배수를 행하고, 탈수행정을 반복한 후 세탁과정을 종료하게 된다.Thereafter, the same water level as that of the washing water is supplied, the washing motor 5 is restarted, and the washing blade 4 is reversed to the left and right to proceed with a rinsing stroke, and when the rinsing stroke is completed, the drainage is carried out as described above. 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 욕조의 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 the waste of water in the water supply process, the tub water in the tub 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, 욕조물기능키를 선택하면, 마이콤(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. do.

게속하여 욕조물의 급수가 이루어지면, 수위센서(12)의 신호를 받아 급수완료인가를 마이콤은 판단한다. 판단결과, 설정된 수위까지 급수가 완료된 것으로 판단되면, 부저구동부(17)를 동작하여 급수완료경고음을 발생하고 세탁을 진행한다.If water is continuously supplied to the bath water, the microcomputer determines whether water supply is completed by receiving a signal from the water level sensor 12. As a result, when it is determined that the water supply is completed to the set water level, the buzzer driving unit 17 is operated to generate a water supply completion warning sound and proceed with washing.

그리고, 판단결과, 설정된 수위까지 급수가 완료되지 않은 것으로 판단되면, 실제로 욕조물이 다 공급되어 더 이상 급수가 이루어지지 않고 있는 경우에도, 초기 마이콤(10)에서 설정된 급수시간(약 40분)이 완료되어있는가를 판단하여, 설정 급수시간이 완료되었으면, 급수에러로 판단하여 표시부(16)에 급수에러를 표시하거나, 일반 수도물의 급수로 전환하고, 설정급수시간이 완료되지 않았으면, 실제로 욕조물이 다 공급되어 더 이상 급수가 이루어지지 않고 있는 경우에도, 상기 과정을 계속 행한다.If it is determined that the water supply is not completed until the set water level, the water supply time set in the initial microcomputer 10 is about 40 minutes even when the tub water is actually supplied and no water is supplied anymore. If it is determined that the water supply time is completed, and the set water supply time is completed, it is determined that the water supply error indicates a water supply error on the display unit 16, or switches to the water supply of general tap water, and if the water supply time is not completed, the tub water is actually Even when the water is supplied and no water is supplied anymore, the process is continued.

이와 같이, 실제로 욕조물이 다 공급되어 더 이상 급수가 이루어지지 않고 있는 경우에도, 이미 설정된 시간까지 대기한 후 급수에러 또는 일반급수로 전환되기 때문에 급수시간이 길어지게 되는 문제점이 있었다.As such, even when the water is not supplied any more because the tub water is actually supplied, there is a problem in that the water supply time becomes longer because the water is switched to a water supply error or a general water supply after waiting for a predetermined time.

본 발명은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 욕조물이 급수되는 세탁조의 수위변화를 일정시간 체크하여 수위변화가 없을시 일반급수로 전환하여 급수시간을 절약할 수 있는 세탁기의 욕조물 급수 제어방법의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art, check the water level change of the washing tank in which the tub water is supplied for a certain time to switch to the normal water supply when there is no change in water level tub water supply of the washing machine can save water supply time To provide a control method.
