도 2는 본 발명 세탁기의 급수 및 배수이상 확인 방법을 보인 흐름도로서, 수위감지부가 채용되어 마이컴 제어로 구동되는 세탁기에 있어서, 급수개시와 함게 세탁이 진행되면 초기 세탁수량을 감지하는 제1단계(S1-S3)와, 상기 제1단계의 시간을 5분이하로 제한하는 제2단계(S4)와, 5분이 경과한 이후의 세탁수량을 재 감지하는 제3단계(S5)와, 제1단계에서 검출한 세탁수량과 제3단계에서 검출한 세탁수량을 비교하는 제4단계(S6)와, 비교결과 급수밸브이상이면 급수불량 및 급수경보음이 발하는 반면, 배수밸브이상이면 배수불량 및 배수경보음발하도록 하는 제5단계(S7-S9)로 이루어진다.2 is a flow chart showing a method of checking a water supply and drainage abnormality of the washing machine of the present invention, in a washing machine driven by a microcomputer control in which a water level detection unit is employed, the first step of detecting initial washing water amount when washing is started with the start of water supply ( S1-S3), the second step S4 of limiting the time of the first step to 5 minutes or less, the third step S5 of re-detecting the washing water amount after 5 minutes, and the first step In the fourth step (S6) of comparing the amount of washing water detected and the amount of washing water detected in the third step, if the water supply valve is higher than the water supply valve, the water supply failure and the water supply alarm sound, whereas if the drain valve is higher than the drainage water and the drain alarm sound. The fifth step (S7-S9) to be made.
이와같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
세탁기에 전원을 인가하고 원하는 세탁코스를 선택하여 시작스위치를 온하게 되면, 세탁기는 급수를 개시하여(S1) 통상의 세탁행정(S2)을 시작하게 된다.When power is supplied to the washing machine and the desired washing course is selected and the start switch is turned on, the washing machine starts water supply (S1) and starts the normal washing operation (S2).
이때 수위감지부(20)으로 부터의 초기 발진주파수를 마이컴(10)으로 입력시켜 세탁수량(A)을 검출케 한다(S3).At this time, the initial oscillation frequency from the water level detection unit 20 is input to the microcomputer 10 to detect the washing water amount (A) (S3).
그리고, 급수개시후 일정시간인 5분의 경과(S4)를 체크하게 되며, 이때 급수후 설정된 시간이 경과하면 그 시점에서 수위감지부(20)를 통해 입력되는 수위(B)에 따른 주파수를 재차 읽어들인다(S5).Then, the elapsed time (S4) of 5 minutes after the start of the water supply is checked. At this time, when the set time elapses after the water supply, the frequency according to the water level (B) input through the water level sensing unit 20 is again present. Read (S5).
이때의 읽어들인 주파수 수위신호와 초기에 읽어들인 주파수 수위신호를 비교하는데(S6), 그 차를 연산하여 값이 비슷하면 세탁수량이 정상적으로 공급됨으로 판단하고 이후의 세탁과정을 정상으로 진행시킨다(S10).At this time, the read frequency level signal is compared with the initially read frequency level signal (S6). If the difference is calculated and the value is similar, it is determined that the amount of washing water is normally supplied and the subsequent washing process proceeds to normal (S10). ).
그런데, 비교결과 그 차가 현저하면 세탁수량이 줄어듬으로 판단하고 먼저 급수밸브 작동여부를 확인하여(S7) 급수밸브 이상이면 에러표시부(30) 및 경보부(50)를 제어하여 급수이상표시와 함게 경고음으로써 외부로 알리며(S8), 상기한 급수밸브가 정상이면 배수밸브가 비정상임으로 즉시 배수이상표시와 경고음으로 알린다(S9).However, if the difference is remarkable, it is determined that the amount of washing water is reduced. First, check whether the water supply valve is operated (S7). If the water supply valve is abnormal, the error display unit 30 and the alarm unit 50 are controlled to warn the user with a water supply abnormality indication. Notify the outside (S8), if the above water supply valve is normal, the drain valve is abnormal, and immediately informed by the drainage abnormality display and warning sound (S9).
이상에서 살펴본 바와 같이 본 발명은 세탁행정중 세탁수가 줄어들 경우 즉 시 급수이상인지 혹은 배수이상인지를 확인할 수 있으므로 사용자의 보다 빠른 조치를 취하도록 기여한다.As described above, the present invention contributes to taking a faster action of the user since it is possible to check whether the washing water is immediately reduced when the washing water decreases during the washing administration.
