Abstract

본 발명은 진공청소기의 흡입력 제어기술에 관한 것으로, 종래의 진공 청소기에 있어서는 부압에 따라 흡입력을 증가시키게 되므로 청소대상물에 의하여 먼지흡입통로가 막히는 경우 오히려 청소가 되지 않는 상태로 초래하게 되고, 더욱이 흡입력에 의해 카페트와 같은 청소대상물이 일어나는 경우 청소하는데 많은 어려움이 있었는 바, 본 발명은 이를 해결하기 위하여 진공청소기의 청소대상물이 어느 정도의 흡입력에서 먼지흡입로로에 달라붙는지를 확인하여 그때의 회전수를 기억함과 아울러, 그 달라붙은 물체가 떨어지도록 소정시간 동안 모터를 저속으로 운전한 다음 상기에서 기억된 회전수 이하로 운전되게한 것이다.The present invention relates to a suction force control technology of a vacuum cleaner, and in a conventional vacuum cleaner, the suction force is increased according to a negative pressure, so that when the dust suction passage is blocked by a cleaning object, the suction force is caused to be in an unclean state. When cleaning objects such as carpet caused by a lot of difficulties in cleaning, the present invention to solve this problem by checking how much the cleaning object is stuck to the dust suction path at the suction power to the rotational speed In addition, the motor is operated at a low speed for a predetermined time so that the stuck object falls, and then the motor is operated at a speed lower than or equal to the stored speed.
