Description

저전력 소모 대기전력 차단장치{Low Power Consumption Electric Outlet}{Low Power Consumption Electric Outlet}

본 발명은 저전력 소모 대기전력 차단장치에 관한 것으로, 더욱 상세하게는 상용전력 또는 대기전력을 검출하는 전력검출부로 공급되는 전원을 대기전력 시에는 차단되도록 한 저전력 소모 대기전력 차단장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a low-power consuming standby power interrupter, and more particularly, to a low-power consuming standby power interrupter which is powered off when a standby power is supplied to a power detector for detecting commercial power or standby power.

일반적으로 가정 및 사무실 등에서는 전기기구로의 전원 공급을 위해 멀티 탭이나 콘센트(이하, 콘센트라 통일함)가 널리 사용된다.Generally, a multi-tap or an outlet (hereinafter referred to as a receptacle) is widely used for power supply to an electric appliance in a home or office.

한편, 전기기구의 파워스위치가 오프 상태일지라도 전기기구의 전원플러그를 콘센트로부터 분리시키지 않으면, 콘센트의 소켓에 인가된 전류가 전기기구의 플러그를 통해 해당 전기기구로 시간당 대략 5W정도로 인가되는 것으로 알려지고 있다.On the other hand, it is known that, even if the power switch of the electric apparatus is in an off state, unless the power plug of the electric apparatus is disconnected from the outlet, the electric current applied to the socket of the outlet is applied to the electric apparatus through the plug of the electric apparatus, have.

이 때문에 콘센트를 사용함에 있어 전기기구를 사용하지 않을 때에는 전원플러그를 콘센트로부터 완전히 분리시켜야 대기전력 손실을 줄일 수 있다.For this reason, when using the outlet, when the electric apparatus is not used, the power plug must be completely disconnected from the outlet to reduce the standby power loss.

이처럼 전기기구가 오프되어 있는 상태일지라도 전기기구가 콘센트에 연결되어 있으면 대기전력 손실이 발생하기 때문에 대기전력 손실을 예방하기 위해서는 전기기구의 전원플러그를 콘센트로부터 완전히 뽑아야 한다.Even if the electric apparatus is turned off, the electric power supply plug of the electric apparatus must be completely disconnected from the outlet in order to prevent the standby power loss because standby power loss occurs when the electric apparatus is connected to the outlet.

그렇지만, 전기기구의 사용을 중지시킬 때마다 매번 전원플러그를 뽑는 일은 매우 번거로운 일이기 때문에 통상 가정이나 사무실 등에서는 대기전력이 소모되는 것을 알고 있으면서도 전기기구와 콘센트를 계속 연결시켜 놓은 상태에서 전기기구의 전원만을 오프 시키고 있는 실정이어서, 대기전력이 손실되는 문제점이 있었다.However, it is very troublesome to unplug the power plug every time when the use of the electric device is stopped. Therefore, while it is known that the standby power is consumed in a home or office, There is a problem that standby power is lost.

2, the external interface unit 740 includes a recovery button unit 745, a status notification unit 743, and a wireless receiving unit 741. The external interface unit 740 is detachably connected to the external interface unit 740, 730, the status notification unit 750, and the wireless reception unit 760, respectively.

상술한 바와 같이 이루어진 저전력 소모 대기전력 차단장치는 다음과 같이 동작한다.The low power consumption standby power cutoff device operated as described above operates as follows.

먼저, 상시모드인 경우, SMPS(210)로 교류전원(100)의 공급이 차단되어, 대기전력 차단장치는 작동을 하지 않는 상태로 되고, 전원차단부(500)는 ON상태로 되어 전원출력부(600)로 전원이 공급된다.First, in the normal mode, the supply of the AC power source 100 is cut off by the SMPS 210, the standby power cutoff device is not operated, the power cutoff unit 500 is turned on, (600).

이어서, 절전모드인 경우, SMPS(210)가 교류전원(100)을 공급받아 대기전력 차단장치를 작동시키기 위한 직류 전원을 출력하며, 대기전력 차단장치는 절전모드로 작동한다.Then, in the power saving mode, the SMPS 210 receives the AC power supply 100 and outputs DC power for operating the standby power cutoff device, and the standby power cutoff device operates in the power saving mode.

이어서, 절전모드에서 전기기기의 플러그가 콘센트인 전원출력부(600)에 연결되면, 미리 설정된 시간이 흐른 후 전기기기의 대기전력 값이 전력검출부(300)를 통하여 감지되어 저장된다.Then, when the plug of the electric device is connected to the power output unit 600, which is an outlet, in the power saving mode, the standby power value of the electric device is sensed and stored through the power detection unit 300 after a preset time.

이어서, 대기전력 값이 설정된 상태에서 전기기기가 연결되기만 하고 작동을 하지 않으면, 소비전력과 대기전력은 동일한 상태가 되므로 대기전력 상태로 판단되어 일정 시간이 지난 후 메인제어부(400)는 전원차단부(500)를 OFF로 작동시켜 전원출력부(600)로 공급되는 전원을 차단시킨다.Then, when the standby power value is set and the electric device is connected but does not operate, the power consumption and the standby power become the same, so that the main control unit 400 determines the standby power state, The power supply unit 500 is turned off to cut off the power supplied to the power output unit 600.

이어서, 메인제어부(400)를 통하여 전원차단부(500)를 오프 시킨 제어 신호는 전류센서 제어부(230)로 전달되어, NPN 트랜지스터를 구동시키면, 전류센서 제어부(230)는 오프 상태로 전환되어 SMPS(210)에서 전력검출부(300)로 전원 공급이 차단된다.The control signal that turns off the power shutoff unit 500 through the main control unit 400 is transmitted to the current sensor control unit 230 to drive the NPN transistor so that the current sensor control unit 230 is turned off, The power supply from the power detector 210 to the power detector 300 is interrupted.

아울러, 메인제어부(400)는 전원차단부(500)를 ON으로 작동시켜 전원출력부(600)로 전원을 공급하면, 메인제어부(400)를 통하여 전원차단부(500)를 온 시킨 제어 신호는 전류센서 제어부(230)로 전달되어, NPN 트랜지스터를 구동시키며, 전류센서 제어부(230)는 온 상태로 전환되어 SMPS(210)에서 전력검출부(300)로 전원이 공급된다.
When the main controller 400 turns on the power cutoff unit 500 and supplies power to the power output unit 600, the control signal that turns on the power cutoff unit 500 through the main control unit 400 The current sensor control unit 230 is turned on and power is supplied from the SMPS 210 to the power detection unit 300.

상술한 바와 같이 본 발명의 저전력 소모 대기전력 차단장치에 따르면, 상용전력 또는 대기전력을 검출하는 전력검출부(300)로 공급되는 전원을 대기전력 시에는 차단되도록 하여, 대기전력 시에 전원출력부(600)로 공급되는 전원뿐만 아니라 전력검출부(300)로 공급되는 전원도 차단시킴으로써, 더욱 전력 소모를 줄일 수 있다.As described above, according to the low power consumption standby power interruption device of the present invention, the power supplied to the power detection unit 300 for detecting the commercial power or the standby power is cut off during standby power, 600, as well as the power supplied to the power detector 300, the power consumption can be further reduced.

이상의 설명에서는 본 발명의 바람직한 실시예를 제시하여 설명하였으나, 본 발명이 반드시 이에 한정되는 것은 아니며, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경할 수 있음을 쉽게 알 수 있을 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, It will be readily apparent that various substitutions, modifications, and alterations can be made herein.
