Description

【0001】
【発明の属する技術分野】
本発明は、電気機器の無駄な電力消費量を最少限にするために電源遮断を行う装置に関する。
【0002】
【従来の技術】
家庭用電気機器、とくにテレビジョン受像機を含むAV機器は、常時使用する訳ではないが、非使用時に電源をオフとせずに、使用時に直ちに動作開始できるように待機状態にしていることが多い。
【0003】
テレビジョン受像機における待機状態での電力消費は、一般に10W程度であり、映像を映しているときの電力消費100W程度に比べて10%程度である。
【0004】
【発明が解決しようとする課題】
この待機状態における電力消費は、電力値では小さいが、待機時間全体を通算するとかなり大きな電力量となる。しかも種々の機器が何れも待機状態であるとすると、その合計消費電力量は膨大なものとなる。
【0005】
そして、電力消費は環境問題との関連でも低減が呼び掛けられており、なんらかの改善が求められている。
【0006】
本発明は上述の点を考慮してなされたもので、電気機器の待機状態での電力消費を最少化する節電用電源遮断装置を提供するものである。
【0007】
【課題解決のための手段】
本発明は上述の点を考慮してなされたもので、
リモコン信号を受信して出力を生じる受信回路と、
この受信回路の出力に応じて始動し、所定時間持続する時限出力を形成するタイマ回路と、
商用電源路に挿入され、制御信号が与えられる度にオン、オフ反転動作して前記商用電源路のオン、オフを行うラッチングリレーと、
前記タイマ回路の時限出力の立ち上がりおよび立ち下りで瞬時型の信号を形成し、前記制御信号として前記ラッチングリレーに与える出力制御回路と、
前記商用電源路に流れる電流が所定値を上回るとき前記タイマ回路に出力を与えて前記時限出力の形成動作を継続させ、下回ったとき前記タイマ回路への出力を停止する電流検知回路と、
をそなえた節電用電源遮断装置、
を提供するものである。
【0008】
【発明の実施の形態】
図1は、本発明の一実施例の構成をブロック線図として示したものである。ここでは、リモートコントロール(以下、単にリモコンという。)式のテレビジョン受像機(以下、単にテレビという。)を本発明の装置により電源遮断を行う対象電気機器として想定している。
【0009】
本発明の装置は、入力端子INが商用電源に接続され、出力端子OUTにテレビが接続される。そして、入力端子INと出力端子OUTとの間にラッチングリレー1および電流検知回路2が挿入されており、これら両者に跨るように手動SW(スイッチ)3が接続されてテレビへの給電路を開閉するようにしている。
【0010】
すなわち、テレビ・リモコン(図示せず)からの、通常は赤外線によるリモコン信号をリモコン受光回路1により受信し、出力をタイマ回路5に与える。タイマ回路5は、これとは別に電流検知回路2の出力も与えられ、これらの一方が与えられれば出力をラッチングリレー1に与える。このラッチングリレー1は、瞬時励磁によりオン、オフ反転動作し、反転後の状態を自己保持するものである。
【0011】
リモコン受光回路4,タイマ回路5および出力制御回路6の電源は、太陽電池7から充電回路8を経て充電電池9に蓄電、供給される。
【0012】
いまテレビリモコンで、テレビの「電源オン」の操作がされてリモコン受光回路4が受信し、出力をタイマ回路5に送出したとする。これによりタイマ回路5は、設定された所定時間持続する出力を出力制御回路6に与える。出力制御回路6は、タイマ回路5の出力の立ち上がりを検出したとき瞬時出力を形成してラッチングリレー1に与え、ラッチングリレー1を反転動作、つまり現状でオフであればオンにさせる。
【0013】
この結果、商用電源から図示しないテレビに給電され、電流検知回路2が給電電流を検知する。このときはテレビリモコンが「電源オン」の操作をされただけであるから、電流検知回路2の検知電流は所定値以下であり、タイマ回路5に出力を与えない。
【0014】
次いで、テレビリモコンの更なる操作が行われてチャンネル選択が行われると、画像が映し出され、給電電流が大幅に増加する。これを電流検知回路2が検知してタイマ回路5に出力を与える。これにより、タイマ回路5は出力を形成し続けるからタイマ回路5の出力には変化がなく、出力制御回路6は出力を生じない。
したがって、テレビは画像を映し出した状態を継続する。
【0015】
他方、テレビリモコンの「電源オン」操作からタイマ回路5に設定された所定時間の間、テレビリモコンの更なる操作が行われないと、電流検知回路2からタイマ回路5に対して出力が与えられないから、タイマ回路5は出力を生じなくなる。この出力が消失する立ち下がりを出力制御回路6が検知して、瞬時出力をラッチングリレー1に与えて反転動作させ、テレビへの給電を遮断する。
【0016】
テレビの機種によるが、受信電波が終了すると画像が消失して待機状態に移行するものでは、放送終了時にテレビへの給電電流が減少する。したがって、電流検知回路2がタイマ回路5に出力を与えなくなり、所定時間を経てタイマ回路5の出力が消失するとその立ち下がりを出力制御回路6が検出して、ラッチングリレー1に瞬時出力を与える。これにより、テレビへの給電路が開放されてテレビが「電源オフ」の状態となり、待機状態での給電が終了する。
【0017】
この後にテレビリモコンの「電源オン」操作が再び行われれば、上述の動作が再現されてテレビへの給電が行われる。
【0018】
図2は、本発明の他の実施例の回路構成を示したものである。この実施例は、回路電源を図1の太陽電池の替わりに、出力端子OUTから取るようにした点に特徴がある。
【0019】
図3は、本発明のさらに他の実施例の回路構成を示したものである。この実施例は、テレビが設置された空間に人が存在するときに給電可能とするものであり、人体検知センサ11およびそれに従動する回路を設けた点に特徴がある。
【0020】
人体検知センサ11は、焦電センサ、超音波センサ、光電センサ等の種々の形式のものを用いることができ、所定の空間に人が存在すると出力を生じるもので、この出力はタイマ回路12に与えられる。人体センサ11およびタイマ回路12は共に電池13から給電される。
【0021】
すなわち、テレビが設置された空間に人が入ってくると、人体検知センサ11が人を検知してタイマ回路12に出力を生じさせる。タイマ回路12の出力に応じて電源制御回路14が電源回路15を作動させてテレビリモコン回路4、タイマ回路5,出力制御回路6に電源供給を行う。
【0022】
(変形例)
上記実施例では、テレビを対象機器としたが、それ以外の電気機器についても待機状態で消費電力が減少する機器であれば、本発明を適用できることは無論である。
【0023】
【発明の効果】
本発明は上述のように、リモコン受信回路の出力および機器電流検出用の電流検出回路の出力によって動作するタイマ回路の出力が継続しているか途切れるかに基づき、ラッチングリレーを作動させて電気機器の電源遮断を行うようにしたため、リモコン操作が長時間行われず機器が待機状態になったときには直ちに電源を遮断して節電を図る。

BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for shutting down a power supply in order to minimize wasteful power consumption of an electric device.
[0002]
[Prior art]
Household electrical equipment, particularly AV equipment including a television receiver, is not always used, but is often in a standby state so that it can be started immediately when used without being turned off when not in use. .
[0003]
The power consumption in the standby state in a television receiver is generally about 10 W, which is about 10% compared to the power consumption of about 100 W when a video is being projected.
[0004]
[Problems to be solved by the invention]
The power consumption in the standby state is small in terms of the power value, but the total amount of power is considerably large when the entire standby time is added. Moreover, if all the various devices are in a standby state, the total power consumption is enormous.
[0005]
And power consumption is also called for reduction in relation to environmental problems, and some improvement is required.
[0006]
The present invention has been made in consideration of the above-described points, and provides a power-saving power cutoff device that minimizes power consumption in a standby state of an electric device.
[0007]

Power-saving power shut-off device with
Is to provide.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. Here, a remote control (hereinafter simply referred to as “remote control”) type television receiver (hereinafter simply referred to as “television”) is assumed as a target electrical device that is powered off by the apparatus of the present invention.
[0009]
In the apparatus of the present invention, an input terminal IN is connected to a commercial power source, and a television is connected to the output terminal OUT. A latching relay 1 and a current detection circuit 2 are inserted between the input terminal IN and the output terminal OUT, and a manual SW (switch) 3 is connected to open and close the power supply path to the television. Like to do.
[0010]
That is, the remote control light receiving circuit 1 receives a remote control signal, which is normally infrared, from a television remote control (not shown), and provides an output to the timer circuit 5. In addition to this, the timer circuit 5 is also provided with the output of the current detection circuit 2, and when one of these is given, the output is given to the latching relay 1. The latching relay 1 is turned on and off by instantaneous excitation and self-holds the state after the inversion.
[0011]
The power of the remote control light receiving circuit 4, the timer circuit 5 and the output control circuit 6 is stored and supplied from the solar battery 7 to the charging battery 9 via the charging circuit 8.
[0012]
Assume that the TV remote control is operated to turn on the TV, the remote control light receiving circuit 4 receives the signal, and the output is sent to the timer circuit 5. As a result, the timer circuit 5 gives the output control circuit 6 an output that lasts for the set predetermined time. When detecting the rise of the output of the timer circuit 5, the output control circuit 6 forms an instantaneous output and applies it to the latching relay 1, and turns on the latching relay 1 if it is in an inversion operation, that is, currently off.
[0013]
As a result, power is supplied from a commercial power source to a television (not shown), and the current detection circuit 2 detects the supply current. At this time, since the television remote controller is only operated to “power on”, the detection current of the current detection circuit 2 is not more than a predetermined value, and no output is given to the timer circuit 5.
[0014]
Next, when a further operation of the TV remote control is performed to select a channel, an image is displayed and the feeding current is greatly increased. This is detected by the current detection circuit 2 and an output is given to the timer circuit 5. As a result, the timer circuit 5 continues to produce an output, so the output of the timer circuit 5 is not changed, and the output control circuit 6 does not produce an output.
Accordingly, the television continues to display the image.
[0015]
On the other hand, if no further operation of the TV remote controller is performed for a predetermined time set in the timer circuit 5 from the “power on” operation of the TV remote controller, an output is given from the current detection circuit 2 to the timer circuit 5. Therefore, the timer circuit 5 does not produce an output. The output control circuit 6 detects the falling edge at which this output disappears, applies the instantaneous output to the latching relay 1 and inverts the power supply to the television.
[0016]
Depending on the TV model, if the received radio wave ends, the image disappears and the standby state is entered, so that the current supplied to the TV decreases when the broadcast ends. Therefore, the current detection circuit 2 does not give an output to the timer circuit 5, and when the output of the timer circuit 5 disappears after a predetermined time, the output control circuit 6 detects the fall and gives an instantaneous output to the latching relay 1. As a result, the power supply path to the television is opened, the television is in a “power off” state, and the power supply in the standby state ends.
[0017]
Thereafter, if the “power on” operation of the TV remote control is performed again, the above-described operation is reproduced and power is supplied to the TV.
[0018]
FIG. 2 shows a circuit configuration of another embodiment of the present invention. This embodiment is characterized in that the circuit power supply is taken from the output terminal OUT instead of the solar cell of FIG.
[0019]
FIG. 3 shows a circuit configuration of still another embodiment of the present invention. This embodiment is characterized in that power can be supplied when a person is present in a space where a television is installed, and a human body detection sensor 11 and a circuit that follows the human body detection sensor are provided.
[0020]
The human body detection sensor 11 can use various types of sensors such as a pyroelectric sensor, an ultrasonic sensor, a photoelectric sensor, and the like. An output is generated when a person is present in a predetermined space. Given. Both the human body sensor 11 and the timer circuit 12 are supplied with power from the battery 13.
[0021]
That is, when a person enters the space where the television is installed, the human body detection sensor 11 detects the person and causes the timer circuit 12 to generate an output. In response to the output of the timer circuit 12, the power supply control circuit 14 operates the power supply circuit 15 to supply power to the television remote control circuit 4, the timer circuit 5, and the output control circuit 6.
[0022]
(Modification)
In the above embodiment, the target device is a television, but it goes without saying that the present invention can be applied to other electrical devices as long as the power consumption is reduced in a standby state.
[0023]
【The invention's effect】
As described above, the present invention activates the latching relay based on whether the output of the timer circuit operated by the output of the remote control receiver circuit and the output of the current detection circuit for device current detection is continued or interrupted. Since the power is cut off, the remote control operation is not performed for a long time, and when the device enters a standby state, the power is turned off immediately to save power.
