Description
The utility model belongs to a kind of additional device of household electrical appliances, it be for improve household electrical appliances function, protection household electrical appliances safely, the distant color remote power-off device that increases the service life and design.
Remote control colour TV set is the electrical equipment of Modern Family's indispensability, owing to its picture is analysed clearly, simple to operate being greatly favored by consumers.But it also comes with some shortcomings: after shutting down with remote controller; can not turn off general supply; just suspend shutdown; also need before machine, to turn-off general supply; could guarantee the safety of colour TV; when starting shooting once more; could open power supply before also will arriving machine; in order to overcome this shortcoming; the inventor had once designed continuously: remote control colour TV set automatic switch (ZL90210259.1), the all-round protection automatically of multi-functional automatic switch of remote control colour TV set (ZL91222014.7) and remote control colour TV set controller (ZL94228439.9).Though they can realize the general supply with remote controller open and close colour TV, do not consider the problem that anti-extraneous signal disturbs and power supply signal disturbs, so that often misoperation takes place.In addition, circuit originally is more complicated also, is unfavorable for producing and debugging.
The purpose of this utility model provides a kind of novel remote control colour TV set circuit breaker, and it not only can realize the remote control switch power supply, and the circuit simplification, can be anti-interference.
The purpose of this utility model is achieved in that it comprises that first and second time voltage stabilizing circuit, governor circuit, latching circuit on casing, wiring board and the wiring board, main points are behind first time voltage stabilizing circuit and connect anti-interference circuit.
Said governor circuit comprises infrared receiving terminal polyphone variable resistor, is connected to the base stage of triode, is connected to base stage, control relay and the contact thereof of back utmost point triode via resistance.
Said anti-jamming circuit comprises, with voltage stabilizing circuit and the triode that connects and the resistance, the electric capacity that are connected on transistor base.
Said latching circuit, it comprises resistance and two diodes, the adjustable resistance in parallel that is connected on the power circuit, current-limiting resistance is connected to the base stage of the triode of governor circuit, is connected to the base stage of governor circuit triode again by diode and resistance.
During use the utility model is connected between power supply and the colour TV, is called " son control device " as power-supply controller of electric, the original remote controller of colour TV is as " female distant device ", is held in people's the hand with remote control control device, and a distant control is collectively referred to as " mother and sons' remote controller ".After the energized, under the control of child control device, distant color no power, when staff is pressed the remote controller pause button, remote control control device begins to make distant coloured silk transfer holding state to the colour TV energising.Meanwhile, distant coloured silk has also been received the machine signal and has been started working.When distant coloured silk is worked at the beginning, produce a locking control signal by power supply immediately, make the locking of son control device, continue normal operating conditions is kept in the colour TV power supply.In the time of need shutting down, with the pause button of remote controller, remote control colour TV set enters halted state.This moment, source current reduced greatly, thereby had discharged the latching circuit of sub-control device, and relay is not worked, and has just cut off general supply, reaches the purpose that remote control played, closed power supply.
The utility model has the advantages that three patents of having applied for the inventor compare, owing to be provided with anti-jamming circuit, in the moment of energising, make triode slowly by the end of the voltage stabilizing value by resistance to the charging process of electric capacity, thereby power supply is provided stably, improved antijamming capability, simultaneously, circuit is through complex optimum, and is simple and reliable, easily with the production debugging.
Details of the present utility model provides with following embodiment and accompanying drawing thereof:
Fig. 1, a kind of general illustration of the present utility model.
Fig. 2, a kind of electrical schematic diagram of the present utility model.
With reference to the accompanying drawings 1, the utility model comprises housing 1, power supply plug wire 2, automatically controlled circuit board 4 in the distant colour TV source jack 3, casing, indicator light 5, infrared receiving terminal 6.
With reference to the accompanying drawings 2, automatically controlled circuit of the present utility model comprises voltage stabilizing circuit A1 one time, secondary voltage stabilizing circuit A2, anti-jamming circuit B, latching circuit C, governor circuit D.
A voltage stabilizing circuit A1 wherein comprises resistance R 1, the capacitor C 1, the resistance R 2 that connect and connect, and bridge rectifier D1-D4, with D1-D4 and be connected with capacitor C 2, voltage-stabiliser tube WY1, this circuit is typical voltage stabilizing circuit, no longer describes in detail.
Its secondary voltage stabilizing circuit A2, comprise resistance R 5 and and the voltage-stabiliser tube WY2, the capacitor C 4 that connect, this circuit also is typical voltage stabilizing circuit, no longer describes in detail.
Anti-jamming circuit B, it also is connected in after the WY1 of a voltage stabilizing circuit, comprises triode BG1 and the resistance R 3, the capacitor C 3 that are connected to the base stage of BG1.
Latching circuit C, it is connected between governor circuit and the power circuit, it comprises the resistance R 12 that is connected on the power circuit and R12 and the diode D7, the D8 that connect, adjustable resistance W2, the base stage that current-limiting resistance R11 that links with W2 and capacitor C 7 are connected to triode BG4, is connected between BG4 and the governor circuit at diode D6, resistance R 10.
Governor circuit D, it comprises infrared receiving terminal HS and adjustable resistance W1, and the capacitor C 6 that connects, the base stage that resistance R 9 is connected to BG3, capacitor C 5, resistance R 7 that the output of BG3 has resistance R 8 to connect and connects, through the base stage of resistance R 6 to triode BG2, the break-make of two normally opened contact JK1, the JK2 of control relay J.DX is a signal lamp, and R4 is a shunt resistance, and D5 is the diode that relay J is played stabilization.
The course of work of the present utility model is: when the HS infrared receiving terminal receives the signal that remote controller sends, with the conducting of W1 adjustable resistance, the current potential of resistance R 9 and capacitor C 6 is descended, make triode BG3 conducting, through 5 chargings of 8 pairs of capacitor C of resistance R, resistance R 7 current potentials raise, make triode BG2 conducting by resistance R 6, thereby make the relay J adhesive, drive its contact JK1, JK2 and connect the 220V power supply, remote control colour TV set is powered.At this moment, remote control colour TV set transfers holding state to, has also received the signal that remote controller sends, and plays machine work.So the two ends of the resistance R 12 in the latching circuit and diode D7, D8 and adjustable resistance W2 produce a locking control signal, make the BG4 conducting by current-limiting resistance R11, make BG3 conducting more by diode D6 and current-limiting resistance R10.This moment, the signal of remote controller stopped, but latching circuit has locked work, had realized the normal machine that rises of distant coloured silk.
When needs shut down, the pause button that uses a teleswitch, at this moment source current subtracts greatly, and locking control signal can not make BG4 and BG3 conducting, discharges to cause relay J, and JK1, JK2 disconnect, thereby reach the purpose of cutting off general supply.
The operation principle of anti-jamming circuit is: power connection in a flash, triode is in conducting state, begin charging by 3 pairs of capacitor C 3 of resistance R, charging in seconds finishes, BG3 is reached after the voltage stabilizing value of WY1 slowly and end, thereby provide power supply to control circuit very stably, improved anti-jamming capacity.
