Description

세탁기의 언발란스 에러보정방법How to correct unbalance error of washing machine

본 발명은 세탁기의 언발란스 에러보정방법에 관한 것으로, 특히 본탈수시 혹은 일련의 세탁행정중 탈수운전시 세탁조의 언발란스에 의한 에러경보후 임의로 설정된 시간동안 탈수가 이루어지지 않도록 한 세탁기의 언발란스 에러보정방법에 관한 것이다.The present invention relates to an unbalance error correction method of a washing machine, and in particular, an unbalance error correction method of a washing machine which prevents dehydration for an arbitrarily set time after an alarm warning due to an unbalance of a washing tank during dehydration during a main dehydration or a series of washing operations. It is about.

일반적으로 세탁기의 언발란스감지는 세탁기의 저수조 외측 상단에 장착되는 안전스위치에 작동횟수로 감지하도록 되었다. 즉 상기 안전스위치의 언발란스 감지는 일련의 세탁행정에서 배수후 발란스탈수시 세탁조를 소정의 시간(4초온,3초오프)동안 4 회정도로 실시하여 상기 첫 번째(7초) 안전스위치의 작동을 감지하고 이어서 두 번째 (7초)동안 상기 안전스위치의 작동유무를 감지하여 이 감지된 안전스위치의 작동횟수로 언발란스를 감지하도록 되어 있어 상기 언발란스를 감지하려면 적어도 4 초동안 모터를 구동하고 이어서 다음 안전스위치의 작동시간까지 7초간을 기다려야만 언발란스를 감지하고, 이때 안전스위치의 작동횟수는 3 회 이상이 되어야 비로서 언발란스로 감지한후 탈수를 정지하고 에러경보를 발하며, 이어서 사용자가 도어를 개폐하게 되면, 언발란스를 보정한 것으로 판단하여 재탈수행정으로 진입하도록 되어 있다.In general, the unbalance detection of the washing machine is to be detected by the number of operation in the safety switch mounted on the outer top of the water tank of the washing machine. That is, the unbalance detection of the safety switch detects the operation of the first (7 seconds) safety switch by performing the washing tank four times for a predetermined time (4 seconds on, 3 seconds off) when the balance is dewatered after draining in a series of washing strokes. And then detect the presence or absence of the safety switch for the second (7 seconds) and detect the unbalance by the number of operation of the detected safety switch. To detect the unbalance, drive the motor for at least 4 seconds and then the next safety switch. If you wait 7 seconds until the operating time of unbalance is detected, the number of operation of the safety switch should be more than three times as non-balanced after detecting the unbalance, stop dehydration and issue an error alarm. In the meantime, it is determined that the unbalance has been corrected, and it is supposed to enter the rehydration administration.

그러나 상기 언발란스에 의한 에러경보후 탈수를 정지하기 위한 세탁조의 관성회전정지시 세탁기는 도어의 개폐상태를 감지하도록 되어 있어 이때 안전스위치가 300msec 이상으로 동작하게 되면 세탁기는 도어가 개폐되었던 것으로 판단하여 재탈수모드로 진입하면서 탈수를 진행하게 되므로 즉 상기 세탁물의 꼬임이 풀어지지 않은 상태에서 다시 재탈수를 하게 되므로 상기 언발란스에 의한 에러 경보시 탈수를 정지하여야 함에도 불구하고 탈수하게 되어 언발란스에 의한 안전스위치의 부딪침을 야기시키게 되므로 저수조의 외상을 손상시키고, 심한 경우에는 세탁기의 흔들림에 의한 이동을 시키게 되어 더욱 더 언발란스를 가중시키게 되는 문제점을 가지게 되었다.However, when the inertia rotation stop of the washing tank to stop dehydration after the error alarm caused by the unbalance, the washing machine is to detect the opening and closing state of the door. If the safety switch is operated at 300msec or more, the washing machine judges that the door is opened and closed again. Since dehydration proceeds while entering the dehydration mode, that is, the dehydration is again performed while the laundry is not untwisted. In the event of an alarm caused by the unbalance, the dehydration should be stopped despite dehydration. Since it causes a bump, damage to the trauma of the reservoir, and in severe cases to move by the shaking of the washing machine has a problem that further increases the unbalance.

본 발명의 목적은 탈수시 언발란스가 감지되어 에러경보 표시후 임의로 설정된 소정의 시간동안은 도어의 개폐상태를 감지하지 않도록 함으로써, 상기 에러경보표시후 재탈수가 되는 것을 방지하도록 하여 보다 안정된 에러경보로 인한 저수조의 진동소음 및 저수조의 손상을 방지할 수 있도록 하고자 하는데 있다.An object of the present invention is to detect the unbalance at the time of dehydration, so as not to detect the opening and closing state of the door for a predetermined time set after the error alarm display, to prevent re-dehydration after the error alarm display to more stable error alarm It is intended to prevent the vibration noise of the reservoir and damage of the reservoir.

상기의 목적을 실현하기 위하여 본 발명은 일련의 세탁이나 헹굼행정이 완료되고 배수가 완료되면 본탈수를 진행하는 단계와, 상기 단계에서 탈수시 안전스위치의 작동에 따른 언발란스를 감지하는 단계와, 상기 단계에서 안전스위치의 작동이 감지되지 않으면 진행중인 탈수가 완료되었는가를 판단하는 단계와, 상기 단계에서 안전스위치의 작동이 감지되면 이 감지된 안전스위치의 작동횟수가 임의로 설정된 소정의 횟수 3 회이상인가를 판단하는 단계와, 상기 단계에서 안전스위치의 작동이 임의로 설정된 소정의 횟수 3회 이상이 아니면 계속해서 탈수하고, 상기 안전스위치의 작동 횟수가 임의로 설정된 소정의 횟수 3 회 이상이면 탈수를 중지하고 언발란스 에러를 경보하고 표시하는 단계와, 상기 단계에서 언발란스 에러경보 표시후 임의로 설정된 소정의 휴지시간이 경과하였는가를 판단하는 단계와, 상기 단계에서 에러 경보표시후 임의로 설정된 소정의 휴지시간이 경과하지 않았으면 에러경보표시하고 휴지하고 , 상기 단계에서 에러경보 표시후 임의로 설정된 소정의 휴지시간이 경과하였으면 도어 개폐를 감지한후 재탈수를 진행하는 단계로 이루어짐을 특징으로 한다.In order to achieve the above object, the present invention is a step of proceeding to the main dehydration when a series of washing or rinsing stroke is completed and drainage is completed, the step of detecting the unbalance according to the operation of the safety switch when dehydration in the step, and If the operation of the safety switch is not detected in the step of determining whether the ongoing dehydration is completed, and if the operation of the safety switch is detected in the step determines whether the detected operation number of the safety switch is a predetermined number of times more than three times set arbitrarily And dehydration is continued if the operation of the safety switch is not more than three times set at random, and if the number of times of operation of the safety switch is set at least three times arbitrarily set, the dehydration is stopped and an unbalance error is detected. Alarming and displaying, and after displaying the unbalance error alarm in this step, Determining whether the predetermined idle time has elapsed; and if the predetermined idle time has not elapsed after the error alarm display in the above step, an error alarm is displayed and paused; After the idle time has elapsed, it is characterized in that the step of proceeding to the dehydration after detecting the door opening and closing.
