본 고안은 가전제품용 누전차단기의 전원스위칭 장치에 관한 것으로서, 특히 가전제품용 푸쉬형 전원스위치의 온,오프 제어로서 가전제품과 누전차단기의 전원을 동시에 제어함으로써 가전제품 전원스위칭 기능과 누전차단기 동작기능을 겸비토록 한 것이다.The present invention relates to a power switching device of an earth leakage breaker for home appliances, and in particular, the on / off control of a push-type power switch for home appliances by controlling the power of the home appliance and the earth leakage breaker at the same time to operate the home appliance power switching function and the earth leakage breaker It has a function.
종래에는 가전제품용 전원스위치와 사용자가 가전제품 사용중에 누전에 의한 감전사고를 미연에 방지하기 위하여 별도로 설치하는 누전차단기용 동작스위치를 각기 설치함에 따라 사용상의 번거로움은 물론 부피가 커지고, 설치비용이 가중되는 문제점이 야기되었다.Conventionally, as the user installs the power switch for home appliances and the operation switch for an earth leakage breaker separately installed in order to prevent an electric shock accident due to a short circuit while the user is using the home appliance, the user is not only troublesome but also bulky. This weighting problem has been caused.
본 고안은 이러한 종래의 문제점을 해소코자 하여 안출한 것으로서, 기존의 가전제품에 설치된 하나의 푸쉬형 전원스위치 만으로 가전제품용 전원 스위치와 누전차단기의 동작스위치 기능까지도 겸할 수 있도록 하여 제품의 콤팩트화는 물론 설치가 용이하고, 또한 제품코스트의 절감을 도모코자 함을 그 목적으로 하는 것이다.The present invention has been made to solve such a conventional problem, and the compactness of the product can be combined with the power switch for home appliances and the operation switch of an earth leakage breaker with only one push-type power switch installed in existing home appliances. It is, of course, easy to install and aims to reduce product cost.
이하, 본 고안을 첨부된 도면에 의하여 상술하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안의 블럭 구성도로서, 이는 전원(AC220V)을 온(ON), 오프(OFF)시키는 푸쉬형 전원스위치(1)와, 제품의 누전상태를 감지하여 부하(3)에 누설전류된 가전제품에 있어서, 누전상태 여부를 감지하여 솔레노이드(6)를 동작시키도록 제어하는 콘트롤러(5)와, 상기 마이컴(4)의 제어하에 콘트롤러(5)에 의해 동작되는 솔레노이드(6)와, 상기 솔레노이드(6) 구동에 따라 전원스위치(1)를 자동적으로 오프(OFF)시키도록 구성된 것이다.1 is a block diagram of the present invention, which is a push-type power switch 1 for turning on and off a power source (AC220V), and a leakage current in a load 3 by sensing a short circuit state of a product. In a home appliance, a controller (5) for controlling the operation of the solenoid (6) by detecting the short-circuit state, a solenoid (6) operated by the controller (5) under the control of the microcomputer (4), According to the driving of the solenoid (6) is configured to automatically turn off (OFF) the power switch (1).
미설명부호 2는 누전 상태를 감지하는 감지기이고, 7은 누전차단기의 정상동작을 시험하는 테스트스위치이다.Reference numeral 2 is a detector for detecting a short circuit condition, and 7 is a test switch for testing the normal operation of the circuit breaker.
이와같이 구성된 본 고안의 작용 및 효과를 제2도를 참조하여 설명하면 다음과 같다.Referring to Figure 2 the operation and effects of the present invention configured as described above are as follows.
먼저, 푸쉬형 전원스위치(1)를 온(ON)시키게되면, 누전감지기(2)에서는 교류전원(AC220V)에 대한 누전상태를 감지하게 되고, 이때 누전상태가 아니면 가전제품인 부하(3)가 정상적으로 동작하게 된다.First, when the push type power switch 1 is turned on, the ground fault detector 2 detects a ground fault state for the AC power source AC220V, and if the ground fault state is not present, the load 3 that is a household appliance is normally It will work.
만일 누전상태이면 누전감지기(2)가 누전상태임을 감지하여 콘트롤러(5)는 제품제어 PCB인 코넥터를 통해 솔레노이드(6)에 제어신호를 보내어 솔레노이드(6)가 동작하여 전원스위치(1)의 양단을 자동적으로 오프(OFF)시키므로 부하(3)에 인입되는 누설 전류를 차단하게 되며, 이때 가전제품이 사용종료가 되면 종료신호를 가전제품의 마이컴(4)이 압력 받아 이를 인식한후 콘트롤러(5)에 제어신호를 보내어 이에 따라 솔레노이드(6)를 동작시키게 되어 전원스위치(1)를 자동적으로 오프 시키도록 한 것이다.If the ground fault state is detected, the ground fault detector 2 detects the ground fault state and the controller 5 sends a control signal to the solenoid 6 through a connector, which is a product control PCB, so that the solenoid 6 operates to operate both ends of the power switch 1. Automatically turns off (OFF) to cut off the leakage current flowing into the load (3), at this time, when the end of the use of the home appliance, the end signal is received by the microcomputer (4) of the home appliance is recognized by the controller 5 By sending a control signal to the) according to which the solenoid (6) is operated to turn off the power switch (1) automatically.
이와같이 본 고안은 가전제품용 누전차단기의 기능과 전원스위칭 기능을 가전제품용 푸쉬스위치 단일 구성만으로 겸용 할수 있도록 하므로서 제품을 소형 콤팩트화할 수 있음은 물론, 누전상태에서는 자동적으로 스위치를 오프 시키므로 제품 사용상의 안전성 및 편리성을 제공하는 유익한 고안인 것이다.As such, the present invention enables the function of the earth leakage breaker for home appliances and the power switching function to be combined with a single push switch for home appliances. It is an advantageous design that provides safety and convenience.
