진공청소기의 물감지 회로Drip sensor circuit of vacuum cleaner

제1도는 진공 청소기의 구조 단면도.1 is a structural cross-sectional view of a vacuum cleaner.

제2도는 본 고안에 따른 물감지 회로도.2 is a water detection circuit diagram according to the present invention.

본 고안은 진공청소기에 관한 것으로 특히 진공청소기를 사용하여 청소를 할 때 물이 진공청소기에 들어오는 것을 감지하여 청소기를 정지시켜 청소기를 보호하는데 적당하도록 한 진공청소기의 물감지회로에 관한 것이다.The present invention relates to a vacuum cleaner, and more particularly, to a water detection circuit of a vacuum cleaner which detects water entering the vacuum cleaner when cleaning using the vacuum cleaner and stops the cleaner to protect the cleaner.

종래의 진공청소기는 제1도에서와 같이, 물감지 센서와 관계된 일체의 회로를 가지고 있지 않고 단지 가변저항에 의한 출력의 제어 혹은 마이콤을 이용하여 위상을 제어하여 출력을 제어하는 회로를 구성하고 있다.The conventional vacuum cleaner does not have any circuit related to the water sensor, as shown in FIG. 1, but constitutes a circuit for controlling the output by controlling the phase by simply controlling the output by a variable resistor or by using a microcomputer. .

그러므로 종래의 청소기는 청소기가 동작을 하고 있을 때 물이 유입되고 있는 상태를 감지할 수가 없어 모터가 계속 회전을 하여 물을 흡입하게 된다.Therefore, the conventional cleaner is unable to detect the state that the water is flowing when the cleaner is operating, the motor continues to rotate to suck the water.

이러한 상태에서 청소기가 계속 동작을하여 물을 흡입하면 청소기 내부에 모터 및 종이 필터가 파손되고 흡입된 물에 의해 누전되어 감전기 될 위험이 있었다.In this state, if the cleaner continues to operate and inhale water, the motor and paper filter are damaged inside the cleaner, and there is a risk of electric leakage due to the sucked water.

따라서 본 고안은 이러한 문제점을 해결하기 위하여 안출된 것으로서 제2도에 도시된 바와같이 수분의 감지를 위한 물감지센서(11)를 흡입파이프(12)내에 설치하고, 물감지센서(11)에 의해 수분이 감지되면 신호처리부(1)에서 수분감지에 따른 신호를 출력하고, 상기 신호 처리부(1)에서 출력되는 신호는 신호 기억부(2)에서 기억된 상태로 제어부(3)에 출력하여 모터(4) 및 수분감지상태 표시 LED(5)를 제어하도록 구성되어 있다.Therefore, the present invention has been devised to solve this problem, and as shown in FIG. 2, a water sensor 11 for detecting water is installed in the suction pipe 12, and by the water sensor 11 When moisture is detected, the signal processor 1 outputs a signal according to moisture detection, and the signal output from the signal processor 1 is output to the control unit 3 in a state stored in the signal storage unit 2 so that the motor ( 4) and the moisture detection state indication LED (5).

즉, 제2도에서 보는 바와같이 흡입파이프(12)내에 설치된 물감지센서(11)의 센서선 사이에 물이 묻으면 센서(11)양단은 쇼트되어 트랜지스터(Q1)의 베이스단이 로우(Low)레벨이 되어 트랜지스터(Q1,Q2)가 온(ON)상태가 되어 저항(R3)을 통하여 전류가 흐르게 되어 로우상태이던 전위(Vo)가 하이상태로 올라가게 된다.That is, as shown in FIG. 2, when water gets between the sensor wires of the water sensor 11 installed in the suction pipe 12, both ends of the sensor 11 are shorted, and the base end of the transistor Q1 is low. ), The transistors Q1 and Q2 are turned on, and current flows through the resistor R3, so that the potential Vo, which was low, rises to a high state.

이 전위가 하이상태로 올라가면 신호 기억부(2)에 입력되어 플립플롭(21)의 프리셋(PR)단에 인가되므로 플립플롭(21)의 출력(Q)은 하이상태로 된다.When this potential rises to the high state, it is input to the signal storage unit 2 and applied to the preset PR stage of the flip-flop 21, so that the output Q of the flip-flop 21 is made high.

이때, 다시 물이 없어져 플립플롭(21)의 프리셋(PR)입력이 로우상태로 내려가게 되어도 플립플롭(21)의 출력(Q)은 계속 하이상태로 유지한다.At this time, even if the water disappears again and the preset PR input of the flip-flop 21 goes low, the output Q of the flip-flop 21 remains high.

따라서 플립플롭(21)의 출력(Q)은 제어부(3)의 입력(IN)으로 작용하며 제어부(3)에서는 출력신호(Q)가 하이상태인 동안은 모터(4)에 인가되는 전원을 끊어서 회전을 정지시키고 LED(5)를 구동하여 물의 유입상태를 표시한다.Therefore, the output Q of the flip-flop 21 serves as the input IN of the controller 3, and the controller 3 cuts off the power applied to the motor 4 while the output signal Q is high. Stop the rotation and drive the LED (5) to indicate the flow of water.

이렇게 물이 감지되어 모터(4)의 출력이 완전히 끊어졌을 때 리셋스 위치(22)를 누르면, 센서선의 물이 제거되었을 경우에는 리셋신호(RES)에 의하여 신호기억부(2)의 플립플롭(21)이 리셋되어 로우상태의 출력(Q)에 의해 모터(4)의 제어가 정상적으로 진행되고, 센서선의 물이 제거되지 않았을 경우에는 다시 플립플롭(21)이 프리셋되어 그대로 모터(M)의 출력이 끊어지게 된다.When the water is detected and the reset switch 22 is pressed when the output of the motor 4 is completely cut off, when the water of the sensor wire is removed, the flip-flop 21 of the signal storage unit 2 is reset by the reset signal RES. ) Is reset and the control of the motor 4 proceeds normally by the output Q in the low state. When the water of the sensor wire is not removed, the flip-flop 21 is preset again so that the output of the motor M remains as it is. It will be cut off.

한편, 본 고안에서 사용된 물감지센서(11)는 두 개의 판을 이용하든지 두 개의 핀을 이용하여 물을 감지해 낼수도 있다.On the other hand, the water sensor 11 used in the present invention may detect the water by using two plates or two pins.

이와같이 본 고안은 흡입파이프(12)를 통하여 물이 흡입되고 있으면 청소기를 정지시킴으로써 청소기의 보호와 감전의 위험을 방지하여 주는 효과를 얻을수 있다.As such, the present invention can obtain the effect of preventing the risk of electric shock and protection of the cleaner by stopping the cleaner when water is sucked through the suction pipe 12.
