본 발명은 진공청소기의 운전제어장치에 관한 것으로, 보다 상세하게는 진공청소기의 흡입부재 저면에 스위치부재를 설치해서 그 스위치부재가 청소대상의 바닥면에 의해 접속되는 여부에 기초하여 흡입력을 조절하도록 된 진공청소기의 운전제어장치에 관한 것이다.The present invention relates to an operation control apparatus for a vacuum cleaner, and more particularly, to install a switch member on the bottom surface of the suction member of the vacuum cleaner so as to adjust the suction force based on whether the switch member is connected by the bottom surface of the cleaning object. It relates to an operation control device of a vacuum cleaner.

일반적으로, 청소대상 지역의 먼지나 이물질을 진공흡입하는 진공청소기는 청소대상지역, 특히 바닥면상에 접촉되어 먼지나 이물질을 진공흡입하도록 이동가능한 흡입부재와, 그 흡입부재를 통해 흡입되는 먼지나 이물질이 통과하는 흡기호스부 및, 상기 흡입부재에 의한 먼지 등의 흡입을 위한 흡기력을 생성하고 상기 흡기호스부를 통과하는 먼지나 이물질을 필터링하는 청소기 본체로 구성된다.In general, a vacuum cleaner which vacuum-injects dust or foreign matter in a cleaning target area, and a suction member movable in contact with the cleaning target region, in particular, the bottom surface, to vacuum inhale dust or foreign matter, and dust or foreign matter sucked through the suction member. And a vacuum cleaner body for generating an intake force for suction of dust and the like by the suction member and filtering dust and foreign matter passing through the intake hose portion.

그러한 구성의 진공청소기에 따르면, 그 운전시 바닥면을 청소하는 경우에는 정상적인 흡입력이 확보되어야만 되지만, 예컨대 흡입부재를 다른 청소대상의 지역으로 이동하기 위해 바닥면으로부터 들어 올리는 경우에도 그 흡입력이 그대로 유지되는 상태로 되어 예컨대 커튼이나 흡입되지 않아야 되는 물건들이 그 흡입부재의 흡기구내로 흡입되어 버리게 되는 일이 빈번하게 초래된다.According to the vacuum cleaner of such a configuration, the normal suction force must be secured when cleaning the floor surface during the operation, but the suction force is maintained even when the suction member is lifted from the floor surface to move to another area to be cleaned. It is frequently caused that the curtains or the objects which should not be sucked are sucked into the suction port of the suction member.

본 발명은 상기한 사정을 감안하여 이루어진 것으로, 흡입부재의 저면에 설치된 스위치부재가 바닥면상에 접속된 상태에서는 정상적인 흡입출력이 확보되고 그 스위치부재가 비접속된 상태에서는 약한 흡입출력으로 운전되도록 제어하는 진공청소기의 운전제어장치를 제공함에 그 목적이 있다.The present invention has been made in view of the above circumstances, and the control unit is operated so that a normal suction output is secured when the switch member provided on the bottom surface of the suction member is connected on the bottom surface, and operated with a weak suction output when the switch member is not connected. It is an object of the present invention to provide an operation control device for a vacuum cleaner.

상기한 목적을 달성하기 위해, 본 발명의 바람직한 실시예에 따르면 청소기 본체의 흡입력에 의해 이동 가능한 흡입부재를 통해 청소대상지역의 먼지나 이물질을 흡입하여 청소하는 진공청소기에 있어서, 상기 흡입부재의 저면에 설치되어 그 흡입부재의 바닥면과의 접촉상태를 검출하는 스위치수단과, 그 스위치수단의 접속상태에 응답하여 상기 흡입부재에 의한 흡입력을 제어하는 제어수단, 그 제어수단의 제어하에 상기 흡입력을 조절하도록 진공모터를 구동하는 모터구동수단을 갖추어 구성된 진공청소기의 운전제어장치가 제공된다.In order to achieve the above object, according to a preferred embodiment of the present invention, in the vacuum cleaner for sucking and cleaning the dust or foreign matter in the area to be cleaned through the suction member movable by the suction force of the cleaner body, the bottom surface of the suction member Switch means for detecting a contact state with a bottom surface of the suction member, control means for controlling the suction force by the suction member in response to the connection state of the switch means, and the suction force under the control of the control means.
