본 발명은 세탁기의 배수펌프 이물질분산방법에 관한 것으로, 특히 배수시 배수펌프에 모여 있는 이물질을 분산하면서 배수할 수 있도록 한 세탁기의 배수펌프 이물질분산방법에 관한 것이다.The present invention relates to a method for dispersing foreign substances in a drainage pump of a washing machine, and more particularly, to a method for dispersing foreign substances in a drainage pump of a washing machine to disperse and disperse foreign matter gathered in a drainage pump.

종래 배수시 오염된 세탁수에 함유된 이물질을 필터를 통해서 걸러주면서 강제배수하는 세탁기의 경우, 상기 필터에는 세탁횟수가 증가함에 따라 세탁시 발생된 이물질이 점점 쌓이게 되고 특히 오염도가 심한 세탁물인 경우 소정의 세탁횟수에 도달하기 전에 필터가 막히게 되어 상기 배수펌프는 구속을 받게 되면서 정상적으로 배수를 하지 못하던가 혹은 세탁을 중지하는 경우가 자주 발생되어 사용자는 자주 필터를 청소해주어야 하는 일련의 세탁행정시 사용자에게 많은 불편함을 주게 되는 문제점을 가지게 되었다.In the case of a washing machine for forced drainage while filtering foreign substances contained in the contaminated washing water during the conventional drainage, foreign substances generated during washing are gradually accumulated in the filter as the number of washing increases, and in particular, in the case of heavily contaminated laundry The filter is blocked before reaching the number of washing of the drainage pump is confined, the drainage is not normally drained or stops washing frequently occurs when the user frequently has to clean the filter in the series of washing administration I have a problem that causes inconvenience.

따라서 본 발명의 목적은 배수시 배수펌프의 부하상태를 감지하여 배수펌프에 과부하가 발생되면, 배수펌프를 역회전시켜 필터에 쌓여있는 이물질을 분산시켜 주면서 배수할 수 있도록 함으로써, 배수시 잦은 배수정지로 인하여 사용자에 불편을 주게 되는 것을 방지하고자 하는데 있다.Therefore, an object of the present invention is to detect the load state of the drainage pump during drainage, if the drainage pump is overloaded, by rotating the drainage pump to disperse the foreign matter accumulated in the filter to drain, frequent drainage stop during drainage This is to prevent the inconvenience to the user.

상기의 목적을 실현하기 위하여 본 발명은 일련의 세탁행정에서 배수시 배수펌프에 전류를 감지하여 이 감지된 전류가 과전류일 경우 배수펌프를 역회전시켜 준후 배수하되, 소정의 횟수이상으로 역회전이 발생하였을 때 배수펌프 막힘을 경보하도록 이루어짐을 특징으로 한다.In order to realize the above object, the present invention detects a current in the drainage pump during drainage in a series of washing strokes, and if the detected current is an overcurrent, the drainage pump is reversed and then drained, but the reverse rotation is more than a predetermined number of times. It is characterized in that it is made to alarm the drainage pump clogging when it occurs.

If the above is made to the drainage pump alarm step (27) to alert the clogging of the drainage pump.

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

세탁기에 전원을 인가하고, 이어서 세탁을 하기 위하여 세탁기에 세탁물을 넣고, 세탁기의 운전신호입력부(가)를 통해서 일련의 세탁행정에 대한 운전신호를 입력하게 되면, 상기 세탁기의 마이콤(나)에서는 입력된 세탁운전신호에 따라 기설정된 소정의 프로그램에 의하여 급수구동부(다)를 제어하여 급수하되, 수위감지부(라)를 통해서 급수되는 수위가 결정된 소정의 수위로 급수가 이루어지는가를 판단하면서 급수를 하고, 상기 급수가 완료되면 모터구동부(마)를 제어하여 펄세이터를 정,역회전시키면서 일련의 세탁행정인 세탁,헴굼을 수행한후, 탈수하는 일련의 세탁행정으로 세탁을 완료하게 된다.When power is supplied to the washing machine, and the laundry is put in the washing machine for washing, and the driving signal for a series of washing administrations is input through the driving signal input unit of the washing machine, the microcomputer (b) of the washing machine inputs the driving signals. The water supply driving unit (C) is controlled to supply water according to the predetermined washing operation signal, and the water is supplied while judging whether the water supply is at a predetermined water level determined by the water level detection unit (D). When the water supply is completed, the motor driving unit (e) controls the pulsator while performing a series of washing operations, washing and hemming while rotating the pulsator forward and reverse.

상기와 같이 일련의 세탁행정을 수행할때 상기 세탁 및 헹굼행정완료시에는 세탁효과를 향상하기 위하여 배수를 하게 되는데, 이때 배수시에는 배수펌프에 의하여 강제배수를 하게 되므로, 배수시 상기 세탁 및 헹굼할때 발생된 이물질이 필터 및 배수펌프를 통해서 배수가 이루어지게 되고, 상기 이물질은 필터와 배수펌프에 쌓이게 되어 배수를 원활하게 하지 못하게 되는 현상을 일으키게 된다.When the washing and rinsing administration is completed when the series of washing administration as described above is to drain in order to improve the washing effect, in this case, because the drainage is forced by the drainage pump, the washing and rinsing when draining When the foreign matter is drained through the filter and the drain pump is made, the foreign matter is accumulated in the filter and the drain pump will cause a phenomenon that the drainage is not smooth.

그러므로 상기 세탁 및 헹굼이 완료되면 상기 마이콤(나)에서는 배수단계(20)로 가서 배수펌프구동부(바)를 제어하여 배수펌프를 구동하면서 강제 배수를 실시하되, 상기 마이콤(나)에서는 배수펌프전류감지단계(21)로 가서 배수펌프전류감지부(사)를 통해서 상기 배수중인 배수펌프의 전류상태를 감지하게 되고, 이어서 상기 마이콤(나)에서는 배수펌프전류판단단계(22)로 가서 상기 감지된 배수펌프의 전류가 기설정된 소정의 전류이상인가를 판단하게 되고, 이때 판단결과 감지된 전류가 기설정된 소정의 전류이상이 아니면 상기 마이콤(나)에서는 배수완료판단단계(23)로 가서 배수가 완료되었는가를 판단하여 배수가 완료되지 않았으면 배수가 완료될때 까지 반복하여 배수를 하게 되고, 반면에 배수가 완료되었으면 다음행정을 수행하게 된다.Therefore, when the washing and rinsing is completed, the microcomputer (b) goes to the drainage step 20 to control the drainage pump driving unit (bar) to drive the drainage pump while performing forced drainage, but in the microcomputer (b) the drainage pump current Go to the detection step 21 to detect the current state of the drain pump in the drain through the drain pump current detection unit (G), and then the microcomputer (b) goes to the drain pump current determination step 22 and the detected It is determined whether the current of the drain pump is greater than or equal to a predetermined current. If the detected current is not greater than or equal to a predetermined current, the microcomputer (b) goes to the drainage completion determination step 23 and the drainage is completed. If the drainage is not completed by judging whether the drainage is completed, the drainage is repeated until the drainage is completed. On the other hand, if the drainage is completed, the next stroke is performed.

한편 상기 배수펌프전류판단단계(22)에서 판단결과 감지된 전류가 기설정된 소정의 전류이상이 이면, 상기 마이콤(나)에서는 필터에 이물질이 쌓여 배수가 이루어지지 않는 것으로 판단하여 상기 마이콤(나)에서는 배수펌프역회전단계(24)로 가서 배수펌프구동부(바)를 제어하여 배수펌프를 순간적으로 역회전시켜 주되, 배수펌프역회전완료판단단계(25)로 가서 상기 역회전이 소정의 시간 완료될때까지 필터에 쌓여 있는 이물질을 저수조로 내불어 상기 이물질을 필터로 부터 분산시켜 준후 배수가 되게 하고, 이어서 역회전횟수판단단계(26)로 가서 상기 필터 막힘에 의한 배수펌프 역회전 횟수가 소정의 횟수 이상 발생되었는가를 판단하여, 판단결과 배수펌프의 역회전횟수가 소정의 역회전 횟수 이상이 아니면 상기 마이콤(나)에서는 배수완료판단단계(23)로 가서 상기 배수가 완료되었는가를 판단하면서 배수가 완료될때 까지 필터에 이물질을 분산시켜 주면서 배수를 진행하게 된다.On the other hand, if the current detected by the drainage pump current determination step 22 is more than a predetermined current, the microcomputer (b) determines that the foreign matter is accumulated in the filter so that the drainage is not made. In the drain pump reverse rotation step (24) to control the drain pump driving unit (bar) to reverse the instantaneous rotation of the drain pump, but to go to the drain pump reverse rotation completion determination step 25, the reverse rotation is completed a predetermined time Blow the foreign matter accumulated in the filter into the water tank until the foreign matter is dispersed from the filter to be drained, and then go to the reverse rotation determination step 26, the number of reverse rotation of the drain pump by the clogging of the filter Judging whether or not more than the number of times the reverse rotation of the drain pump is determined more than the predetermined number of reverse rotations determined by the microcomputer (b) Go to 23 and determined whether the drain is complete, while the dispersion to drain foreign objects into the filter until completed to proceed to drain.

반면에 상기 역회전횟수판단단계(26)로 가서 상기 역회전횟수가 소정의 횟수 이상이면, 상기 마이콤(나)에서는 필터 및 배수펌프에 이물질이 많이 쌓여 배수펌프의 역회전으로도 이물질을 분산할 수 없은 상태로 판단하여 상기 마이콤(나)에서는 배수펌프경보단계(27)로 가서 경보표시부(아)를 제어하여 배수펌프의 막힘을 경보함으로써, 사용자로 하여금 이물질을 제거하게 되는 것이다.On the other hand, if the reverse rotation number determination step 26 goes to the reverse rotation frequency more than a predetermined number of times, the foreign matter is accumulated in the filter and the drain pump in the microcomputer (b) to distribute the foreign matter even in the reverse rotation of the drain pump. The microcomputer (b) determines that the state cannot go to the drain pump alarm step 27 to control the alarm display unit (a) to alert the clogging of the drain pump, so that the user can remove the foreign matter.

이상에서 설명한 바와같이 본 발명은 배수시 배수펌프를 구동하여 강제 배수함에 있어서, 상기 필터에 쌓이게 되는 이물질을 배수펌프를 역회전시켜 필터에 쌓여 있는 물질을 분산시켜 가면서 배수가 이루어지도록 함으로써, 필터의 잦은 이물질 막힘으로 인하여 배수가 증지로 세탁기 이용에 불편함을 해소해 줄 수 있는 효과를 제공하게 되는 것이다.As described above, in the present invention, when the drainage pump is driven and drained, the foreign matter accumulated in the filter is rotated backward to disperse the accumulated material in the filter so as to drain the filter. Due to the frequent clogging of foreign matter, the drainage will provide the effect of relieving inconvenience in using the washing machine.
