The conduction state is maintained until. Therefore, current flows to the gate of the triac 33 during the conduction state of the diaak 34, and the triac 33 is conducted by the gate current. The power voltage is supplied to the motor 31 during the conduction state of the triac 33 so that the motor 31 rotates.
그런데, 종래에는 진공청소기 케이스커버가 닫혔는지의 여부에 관계없이 모터가 동작함으로 해서, 커버가 닫히지 않은 상태에서 모터가 동작할 때, 흡입된 먼지가 다시 외부로 방출되는 문제가 있고, 청소기내부가 상기 먼지로 오염되어 성능이 저하되는 문제가 발생한다.However, in the related art, since the motor operates regardless of whether or not the vacuum cleaner case cover is closed, when the motor is operated without the cover being closed, the sucked dust is discharged to the outside again. There is a problem that the performance is degraded due to contamination with the dust.

이하 첨부한 도면을 참조하여 설명한다.It will be described below with reference to the accompanying drawings.
제 1 도는 본 발명에 의한 모터 및 모터구동을 위한 회로도로써 회전 동작하여 흡입력을 발생하는 모터(21)와 교류전원(22)이 구비되고, 모터구동스위치(25)가 상기모터(21)와 교류전원사이에 직렬연결되어 도통 및 차단동작하는 트라이악(23)을 구비하고, 상기 모터구동스위치(25)의 스위칭동작을 제어하는 트리거신호발생부(26)가 상기 트라이악(23)의 게이트단지와 연결되어 도통 및 차단동작하여 트라이악(23)에 트리거신호인 게이트전류를 인가하거나 차단하는 다이악(24)과, 상기 다이악(24)과 연결되는 캐패시터(C1)와, 상기 캐패시터(C1)와 직렬연결되어 신정수를 결정하는 다수의 저항(R21,R22,R23,R24)과, 상기 저항중 R23,R24와 병렬연결되어 트리거신호(게이트전류)발생시간을 제어하는 가변저항(VR1)을 구비하고, 상기 가변저항(VR1)과 직렬연결되어 케이스커버의 닫힘여부로 스위칭동작하여 상기 트리거신호발생부(26)에 전원을 인가 또는 차단하는 전원제어스위치(11)를 구비한다.1 is a circuit diagram for a motor and a motor drive according to the present invention is provided with a motor 21 and an AC power source 22 for generating a suction force by rotating operation, the motor drive switch 25 is alternating with the motor 21 The triac 23 is connected to the power supply in series and conducts and cuts off, and a trigger signal generator 26 for controlling the switching operation of the motor drive switch 25 is provided at the gate of the triac 23. Connected to and connected to the triac 23 to apply or cut a gate current as a trigger signal to the triac 24; a capacitor C1 connected to the diaac 24; and the capacitor C1. A plurality of resistors R21, R22, R23 and R24 connected in series with each other and a variable resistor VR1 connected in parallel with R23 and R24 among the resistors to control the trigger signal (gate current) generation time. And a case cover connected in series with the variable resistor VR1. The switching operation in Closed Status and a power control switch 11 to the power source to the trigger signal generating section 26 is applied or cut off.
본 발명의 작용 및 효과를 상세하게 설명한다.The operation and effects of the present invention will be described in detail.
제 1 도에서, 모터(21)는 모터구동스위치(26)인 트라이악(23)의 스위칭동작에 의하여 전원전압을 공급받아 회전동적하고, 상기 트라이악(23)은 트리거신호발생부(26)로부터 트리거신호(게이트전류)를 인가받아 도통된다. 그리고, 전원제어스위치(11)는 평상시에는 오프상태이고 케이스커버가 닫힐 때, 상기 커버에 구비되는 돌출부에 의하여 늘려서 온상태가 된다.In FIG. 1, the motor 21 is supplied with a power supply voltage by a switching operation of a triac 23, which is a motor drive switch 26, and the triac 23 is a trigger signal generator 26. As shown in FIG. The trigger signal (gate current) is applied from the circuit and conducts. The power control switch 11 is normally in an off state, and when the case cover is closed, the power control switch 11 is extended by the protrusion provided in the cover to be in the on state.
그런데, 트리거신호발생부(26)에서 상기 전원제어스위치(11)가 온되면 가변저항(VR1)이 트리거신호발생부(26)에 연결됨으로써 폐회로가 구성되어, 상기 트리거신호발생부(26)가 정상적으로 동작한다. 즉 가변저항(VR1)과 캐패시터(C1)에 의하여 결정된 시정수로 상기 캐패시터(C1)에 전압이 충전되고, 상기 캐패시터(C1)에 충전된 전압이 다이악(24)의 브레이크전압이상이면, 상기 다이악(24)이 도통되어, 인가되는 전압이 0이될때까지 상기 도통상태를 유지한다. 그리고, 상기 다이악(24)의 도통으로 트라이악(23)에 게이트전류가 인가되어, 트라이악(23)도 도통된다. 그리하여 모터(21)에 전원전압이 인가되어, 상기 모터(21)가 회전하게 된다.However, when the power control switch 11 is turned on in the trigger signal generator 26, the variable resistor VR1 is connected to the trigger signal generator 26 to form a closed circuit, and the trigger signal generator 26 is It works normally. That is, when the voltage is charged in the capacitor C1 with the time constant determined by the variable resistor VR1 and the capacitor C1, and the voltage charged in the capacitor C1 is equal to or greater than the break voltage of the diaak 24, The diaak 24 conducts and maintains the conduction state until the applied voltage becomes zero. Then, the gate current is applied to the triac 23 by the conduction of the diaak 24, so that the triac 23 is also conductive. Thus, a power supply voltage is applied to the motor 21 so that the motor 21 rotates.
그러나, 진공청소기의 케이스커버가 완전히 닫히지 않은 경우에는 상기 전원제어스위치(11)는 오프상태이므로, 가변저항(VR1)이 단락되어, 트리거신호발생부(20)의 완전한 회로구성이 이루어지지 않는다. 즉 저항(R21,R22,R23,R24)과 캐패시터(C1) 및 다이악(24)과 트라이악(23)에 의하여 폐회로가 구성되긴 하지만, 캐패시터(C1)에 충전되는 전압이 다이악(24)의 브레이크전압(20V-40V)까지 상승하지 못함으로써, 상기 다이악(24)는 도통될 수 없고, 또한 트라이악(23)의 게이트단자에도 전류가 흐르지 않음으로, 트라이악(23)도 도통될 수 없다. 그리하여, 모터(21)의 전원선이 차단되어 모터(21)는 동작하지 않는다.However, when the case cover of the vacuum cleaner is not completely closed, since the power control switch 11 is in an off state, the variable resistor VR1 is short-circuited, and thus the complete circuit configuration of the trigger signal generator 20 is not achieved. That is, although the closed circuit is constituted by the resistors R21, R22, R23, and R24, the capacitor C1, and the diac 24 and the triac 23, the voltage charged in the capacitor C1 is the diac 24. By not rising to the brake voltage of 20V-40V, the diaak 24 cannot conduct, and no current flows through the gate terminal of the triac 23, so that the triac 23 also conducts. Can't. Thus, the power line of the motor 21 is cut off and the motor 21 does not operate.
이와 같이, 본 발명은 진공 청소기의 케이스커버가 완전하게 닫혀져야만, 모터가 동작하도록 함으로써, 사용자의 무성의한 조작에 의하여 진공청소기의 회로성능이 저하되는 것을 막는 우수한 효과가 있는 것이다.As described above, the present invention has an excellent effect of preventing the vacuum cleaner from degrading the circuit performance by the user's inadvertent operation by allowing the motor to operate only when the case cover of the vacuum cleaner is completely closed.
