Abstract

본 발명은 회전드럼식 세탁기에 세탁물의 세탁시 거품이 일정량 이상으로 발생되지 않도록 조절하면서 세탁하는 것으로서 종래에는 발생되는 거품을 제거하지 않고 계속 세탁동작을 수행하였으므로 거품이 많이 발생하여 터브(2)와 회전드럼(3)의 사이에 거품이 충진될 경우에 이거품에 의한 압력에 의해 회전드림(3)의 회전이 방해되어 세탁모타(4)에 과부하가 걸리게 되고, 세탁모타(4)의 구동부가 손상됨은 물론 거품이 급수구(9)를 통해 세제통(6)으로 유입되고, 본체(1)의 톱플레이트(1A)와 세제통(6) 사이의 틈새로 흘러나와 세탁기의 주변을 더럽혔으며, 이러한 현상은 히터를 내장하여 세탁수를 가열하는 기능이 있는 회전드럼식 세탁기에서 더욱 심하게는 발생되었다.The present invention is to wash while washing the laundry in the rotating drum type washing machine so as not to generate more than a certain amount of washing in the conventional washing machine without continuing to remove the generated bubbles, so a lot of foam is generated tub 2 and rotation When foam is filled between the drums 3, the rotation of the rotary dream 3 is prevented by the pressure of the foam, which overloads the washing motor 4 and damages the driving unit of the washing motor 4. Of course, bubbles flowed into the detergent container 6 through the water inlet 9, flowed into the gap between the top plate 1A of the main body 1 and the detergent container 6, and contaminated the surroundings of the washing machine. Silver was more severely generated in a rotary drum type washing machine having a function of heating the wash water by embedding a heater.

본 발명은 거품센서를 설치하여 거품의 발생을 감지하고, 최초로 거품이 일정량 이상으로 발생되었음이 감지될 경우에 세탁모타를 약하게 구동시켜 거품의 발생을 줄이고 설정된 시간이 경과되어도 계속 일정량 이상으로 거품이 발생될 경우에는 세탁수의 일부를 배수 및 보충급수를 2회 반복 수행하여 거품의 발생을 줄이며, 세탁수의 일부를 배수 및 보충급수하여도 계속 거품의 발생될 경우에는 히터를 오프시키고 세탁모타를 정지시켜 거품의 감소되도록 한후 다시 세탁동작을 수행함으로써 거품의 과다발생으로 인한 구동부 및 세탁모타의 손상이 방지되고 세탁효율이 향상됨은 물론 세탁기에서 거품이 흘러나오는 것을 방지할수 있다.The present invention detects the generation of foam by installing a foam sensor, when the first time the foam is detected to generate more than a certain amount of driving the washing motor weakly to reduce the generation of foam and even after a predetermined time elapses the bubble continues to a certain amount If it occurs, drain the part of the wash water and repeat the supplementary water twice to reduce the generation of bubbles.If the part of the wash water continues to generate foam even after draining and replenishing the part of the wash water, turn off the heater and turn off the washing motor. By stopping the foam by stopping and then performing the washing operation again, damage to the driving unit and the washing motor due to the excessive generation of foam is prevented, and the washing efficiency is improved, and the foam can be prevented from flowing out of the washing machine.
