Abstract

본 발명은 진공청소기의 압력센서 감조절환/고장감지장치 및 방법에 관한 것으로, 종래에는 청소기를 사용하는 사용자의 노즐을 누르는 힘이나 청소면과 노즐과의 각도등 사용자의 패턴을 고려하지 않아 최적 흡입력을 제어하는데 오동작을 일으키고 압력센서의 고장감지를 하지 않을 경우에 압력센서의 고정으로 인한 최적 흡입력제어에 크나큰 문제점이 있다. 따라서 본 발명은 압력센서의 고장은 초기 전원투입시 마이크로컴퓨터의 입력포트로 인가되는 전압레벨을 감지하여 고장여부를 체크하고, 압력센서의 감도절환은 감도절환스위치와 콘덴서를 사용하여 시정수에 의한 지연시간으로 압력센서에 맞는 흡입력을 조정함으로써 소비전력을 최대한 줄일 수 있도록 한다.The present invention relates to a pressure sensor control ring / failure detection device and method of a vacuum cleaner, conventionally does not consider the user's pattern, such as the pressing force of the nozzle of the user using the vacuum cleaner or the cleaning surface and the angle of the nozzle does not consider the optimal suction force If there is a malfunction in the control and the failure of the pressure sensor is not detected, there is a significant problem in the optimum suction force control due to the fixing of the pressure sensor. Therefore, in the present invention, the failure of the pressure sensor detects the voltage level applied to the input port of the microcomputer at the initial power-on and checks whether the failure occurs, and the sensitivity switching of the pressure sensor is performed by a time constant using a sensitivity switching switch and a capacitor. By adjusting the suction power to the pressure sensor with the delay time, the power consumption can be reduced as much as possible.
