Description

진공청소기의 플리커 방지회로Flicker prevention circuit of vacuum cleaner

본 발명은 진공청소기의 제어회로에 관한 것으로, 특히 진공청소기 사용중 전원스위치를 온/오프시 순간적으로 전압이 드롭되어 다른 전기장치에 플리커 현상이 발생하는 것을 방지하도록 한 진공청소기의 플리커 방지회로에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control circuit of a vacuum cleaner, and more particularly, to a flicker prevention circuit of a vacuum cleaner which prevents a flicker phenomenon in other electric devices due to an instantaneous voltage drop when the power switch is turned on / off during use of the vacuum cleaner. will be.

제1도는 종래의 진공청소기의 회로도로서, 이에 도시한 바와 같이 전압이 인가되는 전원플러그(1)와; 전원을 연결하는 전원스위치(2)와; 상기 전원스위치(2)가 온(on)됨에 따라 전원이 공급되어 회전하는 전동기(3);로 구성된 것으로, 이의 작용을 설명하면 다음과 같다.1 is a circuit diagram of a conventional vacuum cleaner, and a power plug 1 to which a voltage is applied as shown therein; A power switch 2 for connecting a power source; As the power switch 2 is turned on (on) power is supplied to rotate the electric motor (3), the operation of which is described as follows.

전원플러그(1)에 정격전압이 인가되고, 전원스위치(2)가 온되면 전동기(3)에 전원이 공급되어 전동기(3)는 회전하게 되는데, 이때 전동기(3)의 회전축에 장착된 임펠러를 고속 회전시키게 되므로써 청소기 몸체내부의 공기가 몸체 밖으로 몸체내부의 기압이 대기압보다 낮아진다.When the rated voltage is applied to the power plug 1 and the power switch 2 is turned on, power is supplied to the motor 3 so that the motor 3 rotates. At this time, the impeller mounted on the rotating shaft of the motor 3 is rotated. By rotating at high speed, the air inside the cleaner body is lower than the atmospheric pressure inside the body out of the body.

이에 따라 몸체내부에 흡입력이 발생되어 먼지흡입구의 공기가 이물질과 함께 몸체내부로 빨려들어가 이물질은 집진봉투에 모아지고 정화된 공기는 대기중으로 배출되므로 청소가 행해진다.Accordingly, the suction force is generated in the body, and the air of the dust suction port is sucked into the body together with the foreign matter, and the foreign matter is collected in the dust collecting bag, and the purified air is discharged into the atmosphere, thereby cleaning is performed.

한편, 종래의 진공청소기의 제어회로는 진공청소기를 사용중에 전원스위치를 온/오프할 경우 순간적으로 전압이 드롭(Drop)되어 다른 전기장치가 짧은 시간동안 깜빡거림 현상이 발생하여 사용자에게 불편함을 줄뿐만 아니라, 유럽지역으로 수출하기 위해서는 플리커 규격을 만족하지 못하므로 수출하지 못하는 문제점이 있었다.On the other hand, the control circuit of the conventional vacuum cleaner is inconvenient for the user because when the power switch is turned on / off while the vacuum cleaner is in use, the voltage is dropped instantly and other electric devices flicker for a short time. In addition to the Joule, in order to export to Europe, there was a problem that can not export because it does not meet the flicker specifications.

본 발명은 상기의 문제점을 해소하기 위해 창안된 것으로, 진공청소기 사용중에 전원스위치를 온/오프할 경우 순간적으로 전압이 드롭되어 다른 전기장치가 짧은 시간동안 깜빡거림 현상이 발생하는 플리커를 방지하는데 그 목적이 있다.The present invention was devised to solve the above problems, and when the power switch is turned on / off while the vacuum cleaner is used, the voltage is dropped instantaneously to prevent flicker that causes other electric devices to flicker for a short time. There is a purpose.

제2도는 본발명 진공청소기의 회로도로서, 이에 도시한 바와 같이 전압이 인가되는 전원플러그(1)와; 전원을 연결하는 전원스위치(2)와; 상기 전원스위치(2)가 온됨에 따라 전원이 공급되어 회전하는 전동기(3)와; 입력측이 상기 전원스위치(2)에 연결되고, 출력측의 일측단자가 써지전류 억제저항(R1)에 접속되고 타측단자가 상기 전동기(3)에 접속되며, 초기전원 인가시 전류가 상기 써지전류 억제저항(R1) 및 전동기(3)로 흐르도록 하고, 전원인가후 소정의 시간동안 지연후 전류가 직접 상기 전동기(3)로 흐르게 하는 작동지연부(4);를 포함하여 구성된 것으로, 이의 작용 및 효과를 상세히 설명하면 다음과 같다.2 is a circuit diagram of a vacuum cleaner according to the present invention, and a power plug 1 to which a voltage is applied as shown therein; A power switch 2 for connecting a power source; An electric motor (3) which rotates by being supplied with power as the power switch (2) is turned on; An input side is connected to the power switch 2, one terminal of the output side is connected to the surge current suppression resistor (R1), the other terminal is connected to the motor (3), the current is applied to the surge current suppression resistor when the initial power is applied And an operation delay unit 4 which flows to the R1 and the motor 3 and causes the current to flow directly to the motor 3 after a delay for a predetermined time after the power is applied. When described in detail as follows.

전원을 인가하면 처음에는 콘덴서(C1)가 충전되지 않았기 때문에 분배저항(R4)의 전압이 0.7V 이하이므로 트랜지스터(Q1)는 오프(off)되고 릴레이(RELAY: RY1)가 오프되므로 전류는 릴레이(RY1)의 단자 1에서 단자 2로 흐르므로 써지전류(surge current) 억제저항(R1)을 통해서 전동기(3)에 인가 되므로 전동기(3)는 “최강”으로 회전되는 것이 아니라 “중”으로 회전하게 된다.When the power is applied, since the capacitor C1 is not charged at first, the voltage of the distribution resistor R4 is 0.7 V or less, so the transistor Q1 is turned off and the relay RY1 is turned off. Since it flows from terminal 1 to terminal 2 of RY1, it is applied to the motor 3 through the surge current suppression resistor R1, so that the motor 3 rotates to “medium” rather than to “strong”. do.

상기 콘덴서(C1)에 충전이 계속되는 동안 (수 msec)은 “중”으로 회전하다가 콘덴서(C1)가 완전히 충전되면 분배저항(R4)의 전압이 0.7V 이상이 되므로 트랜지스터(Q1)는 온이 되고 릴레이(RY1)가 온되므로 전류는 릴레이(RY1)의 단자 1에서 단자 3으로 흐르므로 써지전류 억제저항(R1)을 통하지 않고 직접 전동기(3)에 인가되므로 전동기(3)는 “최강”으로 회전하게 된다.While the charging of the capacitor C1 is continued (several msec), the transistor Q1 turns on because the voltage of the distribution resistor R4 becomes 0.7V or more when the capacitor C1 is fully charged. Since relay RY1 is on, current flows from terminal 1 of relay RY1 to terminal 3, so that motor 3 rotates to the "strongest" because it is applied directly to motor 3 without passing through surge suppression resistor R1. Done.

따라서, 진공청소기를 사용하기 위해 전원스위치(2)를 온시키는 순간에 수 미리세크(msec)동안 써지전류(과전류)가 흘러 순간적으로 전압이 드롭(Drop)되면 짧은 시간동안 과전류가 흐르지 못하도록 청소기를 “중” 상태로 지연시킨다.Therefore, if the surge current (over current) flows for several milliseconds (msec) at the moment when the power switch 2 is turned on to use the vacuum cleaner, the vacuum cleaner may be prevented from over current for a short time. Delay to "medium".

이상에서 설명한 바와 같이 본 발명은 전원스위치를 온시키는 순간 청소기 낮은 “중”으로 전동기가 회전하고 수 미리세크(msec)후에 “최강”으로 회전하기 때문에 순간적으로 과전류에 의한 전압 드롭현상이 발생되지 않으므로 다른 전기장치가 짧은 시간동안 깜박꺼림 현상이 발생하는 플리커를 완벽하게 방지할 수 있으며, 아울러 규격을 만족하므로서 유럽지역으로 용이하게 수출할 수 있는 효과가 있다.As described above, in the present invention, since the motor rotates to the "lowest" vacuum cleaner at the moment when the power switch is turned on and rotates to the "strongest" after several milliseconds (msec), the voltage drop phenomenon due to the overcurrent does not occur instantaneously. Other electric devices can completely prevent flicker that flickers for a short time, and it can be easily exported to Europe as it meets specifications.
