Abstract
The utility model belongs to a remote-control AC shutdown controller for TV set of household electrical appliance, which is to add an AC shutdown controller on the basis of the original AC shutdown control switch, wherein the AC shutdown controller is composed of four carbon film resistors R1—R4Three aluminum electrolytic capacitors C1—C3A V19E diode D1Two transistors V1、V2And (4) forming. The utility model discloses an utilize remote control transmitter sleep control button, store the AC shutdown signal, press the shutdown button on the remote control transmitter this moment again, can realize the AC shutdown, if do not need the AC shutdown, as long as eliminate the timing state can. Thus, the television does not need to be added with AC power-off andthe DC power-off switch makes the user not need to set the power-off state before the TV set.
Description
The utility model belongs to a kind of TV remote-control ac dump controller of household electrical appliance.
At present, existing remote control colour TV set will be realized ac dump, need on the colour TV complete machine, increase the control switch of a complete machine shutdown (direct current shutdown) and ac dump, the casing mould also will increase a hole like this, the user uses also inconvenient in addition, ac dump is put into the ac dump position to switch before must arriving television set, otherwise can not realize ac dump.
The objective of the invention is to utilize remote control transmitter sleep control button, store the ac dump signal, this moment is again by the button that shuts down on the remote control transmitter, can realize ac dump, as not needing ac dump, as long as eliminate definition status, as separately by the button that shuts down on the remote control transmitter, still carry out shutdown (AC power is not cut off in the direct current shutdown),, also carry out the remote-controlled start-up function if press remote control transmitter start button.Need not to increase on television set an ac dump and direct current shut down switch like this, the user sets off-mode before also needn't advanceing to television set, directly controls the off-mode of television set with remote control transmitter.
The utility model is achieved in that TV remote-control ac dump controller is to increase an ac dump controller on original ac dump control switch basis.The ac dump controller is by four fixed carbon resister R

The utility model TV remote-control closedown controller, simple in structure, do not need ac dump function operating key, on television set, need not be provided with ac dump or direct current shutdown control switch yet, reduced television set manufacturing process flow process, the user is safe and convenient to use.
Accompanying drawing is a circuit diagram of the present utility model
Below in conjunction with description of drawings most preferred embodiment of the present utility model and operation principle thereof: TV remote-control ac dump controller is to increase an ac dump controller on original ac dump control switch basis.The ac dump controller is by four fixed carbon resister R

4The other end connects V
2Base stage, V
2Grounded emitter, V
2Collector electrode and D
1Negative pole and ac dump control switch one end connect, D
1Positive pole is connected with the control switch other end+12V power supply.Its operation principle is: the ac dump controller is to become low level signal by high level of IC the 6th pin output to pass through capacitor C
3Be coupled to V
1Transistor is because of V
1Be that PNP pipe circuit connects, cut-off state normally, after the base stage input high level becomes the low level pulse signal, V
1Electricity makes V by becoming conducting
1C utmost point low level uprise level, same V
2Base stage b also becomes high level by low level, makes V
2Electricity makes mains switch electromagnet coil L flow through electric current by becoming conducting, and work of electromagnet and mains switch reset, and cut off whole AC power, finish the ac dump function.
