텔레비젼 수상기의 전원 자동차단 회로Power cutoff circuit of TV receiver

첨부된 도면은 본 고안의 회로도이다.The accompanying drawings are circuit diagrams of the subject innovation.

* 도면의 주요부분에 대한 부호 설명* Explanation of symbols on the main parts of the drawings

1. 타이머 2. 수동 스위치부1. Timer 2. Manual Switch

3. 발광램프 4. 시정수 회로3. Light emitting lamp 4. Time constant circuit

본 고안은 텔레비젼방송 시청시에 타이머 회로에 의한 전원 자동차단 기능을 가지도록 하므로써 시청시의 편리함이나 전력절감을 이를 수 있는 텔레비젼 수상기의 전원 자동차단 회로에 관한것이다.The present invention relates to a power cut-off circuit of a television receiver which can bring about a power-saving function by a timer circuit when watching a television broadcast, thereby achieving convenience and power saving.

종래에도 텔레비젼 수상기의 전원 자동차단 회로가 많이 제안된 바 있으나, 이들은 모두 텔레비젼 방송의 유무를 감지하는 회로와 이에 의해 보조 스위치를 언온오프 시키도록 하므로써 텔레비젼 수상기의 전원을 차단하도록 하고 있고, 방송 종료후 일정시간(5초 내지 30초)이후에 자동으로 전원이 차단되도록 한 것이 어서 다음과 같은 점에서 아직도 개선할 점이 남아 있는 것이다.In the past, many power supply cut-off circuits of a television receiver have been proposed, but all of them are designed to cut off the power of the television receiver by turning on and off the circuit for detecting the presence or absence of a television broadcast. Since the power is automatically turned off after a certain time (5 to 30 seconds), there is still an improvement in the following points.

즉, 이들은 텔레비젼 방송의 종료시까지의 시간이 장시간 남아 있는 데도 불구하고 시청자가 선택된 프로그램을 보면서 그대로 잠들 경우에는 그 시점부터 불피로한 전력이 낭비되는 것이므로 바람직한 전원 자동차단 기능을 수행하기 어려운 것이다.In other words, even if the time until the end of the television broadcast is left for a long time, when the viewer falls asleep while watching the selected program, unavoidable power is wasted from that time, it is difficult to perform the desired power cut off function.

또한, 시청자가 기호하는 프로그램 시청이후 시청을 그만두고자 할 때의 의도중에 잠들 경우를 대비한 임의 세팅기능이 없으므로 그 사용상의 편이성이나 융통성이 결연된 것이었다.In addition, since there is no arbitrary setting function in case of falling asleep during the intention when the viewer wants to stop watching after viewing the program that the viewer prefers, the ease of use and flexibility were determined.

본 고안은 종래의 이러한 불편을 해소하고자 안출한 것으로써, 이는 사용자의 임의 세팅동작에 의해 소정의 시간 이후텔레비젼 수상기의 전원을 작동 차단하도록 하므로써, 그 사용상의 편의성, 융통성을 부여하고 불의의 전력낭비를 없앨 수 있는데 그 목적이 있는 것이다.The present invention has been made to solve such inconvenience in the prior art, which allows the power supply of the television receiver to be shut off after a predetermined time by a user's arbitrary setting operation, thereby providing convenience and flexibility in use, and inadvertent power consumption. You can get rid of that purpose.

이하에서 이를 상세히 설명하면 다음과 같다.This will be described in detail below.

주전원 스위치(S1), 보조 전원스위치(S2)를 텔레비젼회로인 부하회로 (Rd)에 연결하고 별도의 보조 전원회로(6)를 설치항 것에 있어서,상기 보조전원회로(6)에 수동스위치부(2)를 설치하며,이의고정접점(b1)은 발광랜프(3),시정수회로(4)가 연결된 타이머(1)의 출력은 역방향 전압방지부(5)의 다이모드(D1)와 연결하며, 또 다른 고정접점 (b2)은 역방향 전압방지부(5)의 다이오드(D2)에 연결하고, 이 역방향 전압방지부(5)의 출력은 릴레이(Ry)구동용 트랜지스터(T)에 연결하여서 된 것이다.In the case of connecting the main power switch S 1 and the auxiliary power switch S 2 to the load circuit Rd, which is a television circuit, and installing a separate auxiliary power circuit 6, a manual switch is provided in the auxiliary power circuit 6. The unit (2) is installed, and the fixed contact point (b 1 ) of the light emitting lamp (3) and the output of the timer (1) to which the time constant circuit (4) is connected are the die mode (D 1 ) of the reverse voltage prevention part (5). ), And another fixed contact (b 2 ) is connected to the diode D 2 of the reverse voltage protection part 5, and the output of the reverse voltage protection part 5 is a relay (Ry) driving transistor ( Connected to T).

미성명 부호 a1, a2, a3,는타이머의 입출력 단자이다. 이러한 구성의 본 고안은 평상시 수동스위치부(2)의 스위치(So)를 고정접점(b2)에 놓을 때는 전원이 역방향 전압방지부(5)의 다이오드(D2)를 거쳐 트랜지스터(T)에 가해지므로 릴레이(Ry)가 동작되어 보조스위치(S2)를 선로와 이어지도록 연결하게 되다.The unnamed symbols a 1 , a 2 , a 3 , are input / output terminals of the timer. According to the present invention of such a configuration, when the switch So of the manual switch unit 2 is normally placed at the fixed contact point b 2 , the power supply is applied to the transistor T via the diode D 2 of the reverse voltage protection unit 5. The relay Ry is operated to connect the auxiliary switch S 2 to the line.

그러므로 정상시의 텔레비젼시청이 가능하다.Therefore, normal TV viewing is possible.

이후 사용자가 임의의 시간, 즉, 소정의 프로그램 시청시간, 이후는 전원을 차단시키거자 할때는 시정수의로(4)의 가변저항(R1)을 외부에서 조정하여 놓은 다음 스위치 (So)를 고정접점(b1)에 절환하면30분, 60분90분 등의 세팅된 시간동안 타이머(1 )의 출력(a3)이 논리레벨 “high”로 있어서 트랜지스터(T)가 언된 상태가 되므로 계속 시청이 가능하지만 소정의 세팅된 시간 이후는 타이머(1) 출력(a3)이 “Low”로 되어 트랜지스터(T)가 오프되므로써 릴레이(Ry)가 오프된다.After that, when the user wants to turn off the power at any time, that is, at a predetermined program viewing time, and then, the variable resistor R 1 of the time constant 4 is adjusted externally, and then the switch So is fixed to the contact point. When switching to (b 1 ), the output (a3) of the timer (1) is at the logic level “high” during the set time such as 30 minutes, 60 minutes and 90 minutes, so that the transistor T is frozen and the viewing is continued. However, after the predetermined time, the relay Ry is turned off because the timer 1 output a 3 becomes “Low” and the transistor T is turned off.

이때, 발광램프(3)에 의해 타이머(1)가 동작되고 있다는 것을 쉽게 확인할 수 있다.At this time, it can be easily confirmed that the timer 1 is operated by the light emitting lamp 3.

이러한 본 고안은 시청자가 자기가 바라는 소정의 프로그램시청 이후에 텔레비젼 수상기가 자동으로 오프되도록 하므로써 불의의 전력낭비를 미연에 방지할 수 있을뿐만 아니라 사용자로써는 용통성 있고 전의성있게 이를 조작할 수 있는 매우 유익한 특징이 있는 것이다.The present invention enables the viewer to automatically turn off the TV receiver after watching a desired program, thereby preventing accidental power wastage and allowing the user to operate it flexibly and deliberately. It is a beneficial feature.
