The controller 15 detects whether or not the current value of the dehydration motor driver 16 falls in the present dehydration mode. The sewage filter net is full and is connected to drive the alarm means (11).

또, 상기 경보수단(11)은 도 3과같이 제어판(2)측에 설치되어 있는 청소시기 표시기(12a)를 포함한 표시부(12)와 부저음을 발생시키는 부저구동부(13) 등으로 이뤄져 있다.The alarm means 11 is composed of a display portion 12 including a cleaning time indicator 12a provided on the control panel 2 side as shown in FIG. 3, and a buzzer driving portion 13 for generating a buzzer sound.

한편, 상기 제어부(15)에는 배수구측에 설치한 오물걸름망에 오물이 많이차게되면 경보동작을 수행하는 도 2와같은 청소시기 경보제어 프로그램(100)이 구비 되어져 있다.On the other hand, the control unit 15 is provided with a cleaning time alarm control program 100 as shown in FIG. 2 to perform an alarm operation when a large amount of dirt fills the dirt trap network installed on the drain outlet side.

여기서는 세탁기 행정중에 배수와 발란스 탈수동작을 수행하는단계(스텝 101 내지 104)와, 이 발란스 탈수 동작이 완료되면 본탈수를 진행하는 단계(스텝 105)와, 본 탈수가 시작되면 탈수행정의 시작과함께 내부카운트의 계수를 시작하고 탈수모터 전류값 x를 측정하는 단계(스텝 105 내지 107)와, 미리정한 임의 시간값에 내부 카운트값이 도달했는가를 판단하여 도달하였으면 탈수모터 전류값을 다시 측정하여 탈수모터 전류값 y를 메모리에 저장하는 단계(스텝 108,109)와, 상기에서 x 값과 y값을 비교하여 탈수모터의 전류치가 떨어지지 않으면 배수구의 오물걸름망이 차있다고 인식하여 경보수단을 구동하는 단계(스텝 110 내지 112) 등을 포함하고 있다.Here, the steps of performing drainage and balance dehydration during the washing machine stroke (steps 101 to 104), and proceeding to main dehydration when the balance dewatering operation is completed (step 105); Start counting the internal count together and measure the dehydration motor current value x (steps 105 to 107), and determine if the internal count value reaches a predetermined random time value, and if so, measure the dehydration motor current value again. Storing the dehydration motor current value y in the memory (steps 108 and 109); and comparing the x value and the y value in the above, and recognizing that the sewage screen of the drain is full if the current value of the dewatering motor does not fall (step 108,109). Steps 110 to 112) are included.

상기 전류치가 떨어질때는 발란스 탈수시와 같이 부하가 점점줄기 때문에 모터의 전류치는 저하되나 배수구의 오물걸름망에 오물이 가득찰때는 배수가 되지않아 저수조 물이 남아있어 탈수모터의 전류는 줄어들지 않으므로 이러한 상태를 제어부(15)가 인식하여 경보수단을 구동하게 되는 것이다.When the current value drops, the load decreases as in the case of dehydration of the balance, but the current value of the motor decreases, but when the filth net of the drain is full, the water is not drained because the water remains in the reservoir and the current of the dewatering motor does not decrease. The controller 15 recognizes and drives the alarm means.

이러한 구성의 본 발명은 세탁기 사용자가 세탁기를 사용하기 위하여 세탁조에 세탁물을 넣은후 도 1예의 키입력부(14)를 통하여 사용자가 원하는 세탁코스를 선택하여 세탁-헹굼-탈수작업을 수행하는 것이다.According to the present invention, a washing machine user puts laundry into a washing tank to use a washing machine, and then selects a washing course desired by the user through the key input unit 14 of FIG. 1 to perform washing-rinse-dehydration.
