Abstract

A control device and method for controlling a vacuum cleaner are disclosed by detecting when a brush is fitted to the cleaner and automatically regulating the suction power. To detect the brush (2) fitting status, the micro computer (5) checks and stores the output status (high or low) and sends a high signal and reads (103) the transistor (TR) collector voltage in the switch at the A/D convertor terminal of the microcomputer (5). The switching means composed of PNP transistors is off when the micro computer sends a high signal. The microcomputer compares the collector voltage with the reference voltage (3.5V) and judges (104) whether a brush is fitted. If the brush is detected, control signal is sent to the motor (9) to reduce the suction power to normal level from maximum level. Without a brush, the power level is changed (111) from normal to maximum.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

첨부된 도면 제1도는 본 발명에 적용되는 진공청소기의 제어장치의 구성도로서, 진공청소기의 본체(1)와 호스로 연결되어 먼지를 흡입하는 기능을 수행하는 브러쉬(2), 상기 브러쉬(2)의 적소에 설치되어 먼지의 유,무를 시각적으로 표시하는 먼지 감지표시등(3), 상기 브러쉬(2)를 운전하는 운전손압이(4)로 구성되어 있다.1 is a configuration diagram of a control device of a vacuum cleaner applied to the present invention, the brush 2 connected to the main body 1 of the vacuum cleaner and a hose to suck in dust, and the brush 2 And a dust detection indicator (3) installed at the right place to visually display the presence or absence of dust, and a driving loss pressure (4) for driving the brush (2).

제2도 본 발명에 따른 진공청소기의 제어방법의 회로도로서, 각종 제어신호를 출력하여 청소동작을 수행하고 A/D변환단자를 갖는 마이크로 컴퓨터(5)의 일측에 접속되며, 상기 브러쉬(2)에 설치된 먼지 감지표시등(3)에 인가되는 전압을 스위칭하고 트랜지스터(TR)로 이루어진 스위칭수단(6), 상기 스위칭수단(6)의 일측과 병렬로 접속되어 상기 브러쉬(2)측에 인가되는 전압을 차단시키며 저항(RI)으로 이루어진 차폐수단(7), 상기 마이크로컴퓨터(5)의 일측에 접속되어 브러쉬(2)의 적소에 설치되는 먼지 감지표시등(3)으로 구성되어 있다.2 is a circuit diagram of a control method of a vacuum cleaner according to the present invention, which outputs various control signals to perform a cleaning operation and is connected to one side of a microcomputer 5 having an A / D conversion terminal, and the brush 2 Switching voltage applied to the dust detection indicator 3 installed in the switching means 6 consisting of a transistor TR, connected in parallel with one side of the switching means 6 and applied to the brush 2 side. The shielding means 7 which cuts off the voltage and consists of a resistance RI and a dust detection indicator 3 connected to one side of the microcomputer 5 and installed in place of the brush 2 is provided.

이와같이 구성된 진공청소기의 제어장치 및 방법을 제2도 내지 제3도에 의해 상세히 설명하면 다음과 같다.The control device and method of the vacuum cleaner configured as described above will be described in detail with reference to FIGS. 2 to 3 as follows.

먼지 전원이 인가되어 진공청소기가 동작을 시작하면 마이크로컴퓨터(5)는 브러쉬(2) 장착상태가 변화하는지의 여부를 판단하기 위하여 현재 출력되는 포트의 상태가 하이 또는 로우인지를 체크하여 저장(단계101)시킨 다음 출력포트에 하이신호를 송출시켜(단계102) 스위칭수단(6)내의 트랜지스터(TR)의 콜렉터 전압을 마이크로컴퓨터(5)내의 A/D 변환단자에서 읽는다.(단계 103)When the dust power is applied and the vacuum cleaner starts to operate, the microcomputer 5 checks whether the state of the currently output port is high or low in order to determine whether the brush 2 is mounted or not. 101) and sends a high signal to the output port (step 102) to read the collector voltage of the transistor TR in the switching means 6 from the A / D conversion terminal in the microcomputer 5 (step 103).

이때, PNP형 트랜지스터(TR)로 구성되어 있는 스우칭수단(6)은 마이크로컴퓨터(5)에서 100ms동안 하이신호가 송출됨으로서 오프상태로 되어 브러쉬(2)측의 먼지감지표시등(3)의 구동전원으로 인가되는 5V의 전원은 100㏀의 저항(R3)으로 이루어진 차폐수단(7)으로 인가되고, 이의 차폐수단(7)의 작용에 의해 약 20mA 의 구동전류가 필요한 먼지감지표시등(3)에 0.05mA 의 전류밖에 인가되지 못하여 먼지감지표시등(3)은 눈으로는 구별할 수 없는 짧은 시간동안 오프상태가 된다.At this time, the switching means 6 composed of the PNP-type transistor TR is turned off by sending a high signal for 100 ms from the microcomputer 5 so that the dust detection indicator 3 on the brush 2 side is turned off. The 5V power source applied as the driving power source is applied to the shielding means 7 composed of a resistor R3 of 100 kW, and the dust sensing indicator 3 needs a driving current of about 20 mA by the action of the shielding means 7. ), Only a current of 0.05 mA is applied, and the dust detection indicator (3) is turned off for a short time which is indistinguishable to the eye.

이후, 마이크로컴퓨터(5)는 A/D변환단자를 통하여 스위칭수단(6)의 트랜지스터(TR)의 콜렉터 전압을 읽고, 설정된 기준값인 3.5V와 비교함으로서 브러쉬(2)의 장착 유,무를 판단하게 된다. (단계 104)Thereafter, the microcomputer 5 reads the collector voltage of the transistor TR of the switching means 6 through the A / D conversion terminal and compares it with the set reference value 3.5V to determine whether the brush 2 is mounted or not. do. (Step 104)

만약, 브러쉬(2)가 연결되어 있지 않다면 A/D변환단자를 통하여 입력된 스위칭수단(6)의 트랜지스터(TR) 콜렉터 전압은 설정된 기준값보다 높은 약5.0V에 근접한 수치가 입력되며, (단계 105) 브러쉬(2)가 연결되어 있을 경우 A/D변환단자를 통하여 입력된 스위칭수단(6)의 트랜지스터(TR) 콜렉터 전압은 설정된 기준값보다 낮은 약 1.0 - 2.0V에 근접한 수치가 입력(단계 106)됨으로서 마이크로컴퓨터(5)에서는 브러쉬(2)의 장착 유,무를 판단하게 된다.If the brush 2 is not connected, the value of the transistor TR of the switching means 6 input through the A / D conversion terminal is close to about 5.0 V, which is higher than the set reference value. When the brush 2 is connected, the transistor (TR) collector voltage of the switching means 6 input through the A / D conversion terminal has a value close to about 1.0-2.0V lower than the set reference value (step 106). As a result, the microcomputer 5 determines whether or not the brush 2 is mounted.

이때 마이크로컴퓨터(5)에서는 출력포트의 상태를 초기에 체크하여 저장해 놓은 상태로 복귀시키고(단계 107), 상기와 같은 동작을 100ms동안 5회 실행하여 500ms동안 A/D변환단자에 입력된 수치가 동일할 경우에는 마이크로컴퓨터(5)는 입력된 수치에 의해 브러쉬(2) 접속 유무의 상태에 대한 최종적인 판단을 하게 된다. (단계 108)At this time, the microcomputer 5 initially checks the state of the output port and returns to the stored state (step 107), and executes the above operation five times for 100 ms and the value inputted to the A / D conversion terminal for 500 ms is In the same case, the microcomputer 5 makes a final judgment on whether the brush 2 is connected or not based on the input value. (Step 108)

즉 마이크로컴퓨터(5)는 100ms동안 5회 실행시 브러쉬(2)의 상태 변화가 있는지를 판단하여(단계109),변화가 없다면 브러쉬가 없는 것으로 인지하여 종전상태를 유지하고(단계 110) 브러쉬(2)가 무 장착상태에서 장착상태로 변화됨이 인지되면 마이크로 컴퓨터(5)는 모터부(9)에 제어신호를 출력하여 진공청소기의 흡입력을 최대 흡입력상태에서 보다 낮은 상태인 노멀상태로 변화시키며, 브러쉬(2)가 장착상태에서 무 장착상태로 변화하면 마이크로 컴퓨터(5)는 모터부(9)에 제어신호를 출력하여 진공청소기의 흡입력을 노멀상태에서 최대 흡입력상태로 변화시키는(단계 111) 동작을 하게 된다.That is, the microcomputer 5 determines whether there is a change in the state of the brush 2 when it is executed five times for 100 ms (step 109). If there is no change, the microcomputer 5 recognizes that there is no brush and maintains the previous state (step 110). When it is recognized that 2) is changed from the non-mounted state to the mounted state, the microcomputer 5 outputs a control signal to the motor unit 9 to change the suction force of the vacuum cleaner from the maximum suction force state to a lower state than the normal state, When the brush 2 is changed from the mounted state to the non-mounted state, the microcomputer 5 outputs a control signal to the motor unit 9 to change the suction force of the vacuum cleaner from the normal state to the maximum suction force state (step 111). Will be

이상에서 상술한 바와 같이 본 발명의 진공청소기의 제어장치 및 방법에서는 청소동작 수행시 브러쉬의 장착 유,무를 감지하여 흡입력을 자동조절시킴으로서 강한 흡입력으로 인한 사용상의 불편한 점을 해소하여 진공청소기의 사용상의 불편한 점을 해소하여 진공청소기의 사용상의 편리성을 증대시키는 장점이 있다.As described above, the control apparatus and method of the vacuum cleaner of the present invention detects the presence or absence of the brush when the cleaning operation is performed and automatically adjusts the suction force, thereby eliminating inconveniences caused by the strong suction force. Eliminating the inconvenience has the advantage of increasing the convenience of use of the vacuum cleaner.
