Description
Technical field is a mains switch under the present technique, relates in particular to the infrared remote control switch of household electrical appliance.
Various types of remote control switches are arranged at present both at home and abroad, the remote control switch of example acoustic control or radio wave control, they all need to carry the emitter of sound wave or radio wave, but sound wave or radio wave are non-directional, therefore the signal launched of this emitter all works to its remote control switch of the same type, so in same room or close on the room such remote control switch only can be installed, many then interfere with each other, can't operate as normal.And existing infrared remote control switch, because infrared ray high directivity, propagate linearly, can not get around barrier,, and not interfere with each other even several such infrared remote control switchs also can be installed in same room, but being it, the shortcoming of this infrared remote control switch must carry special-purpose infrared remote-control emitter, Infrared remote controller to other models is inoperative, does not therefore have versatility, makes troubles to the user.
The purpose of this utility model is the problem that exists at prior art and the general infrared remote control switch of a kind of household electrical appliance power supply of innovation and creation not needing to be characterized in special-purpose remote-control transmitting part, and all kinds of infrared remote-control emitters are had versatility.Easy to use, comfortable, because switch is contactless, so switch is reliable, safety, can prolong the useful life of switch greatly.
The technical solution of the utility model is: the general infrared remote control switch of a kind of household electrical appliance power supply, it partly is made up of power unit and infrared reception and control circuit.Power unit through capacitor charge and discharge formula rectification circuit, makes idle power consumption minimum civil power, to 12V, enters three terminal regulator voltage stabilizing one-tenth+5V DC power supply through the voltage stabilizing didoe voltage stabilizing.
Infrared reception and control circuit part, it comprises infrared receiving diode, receive infrared pulse signal, through dividing potential drop and filter flip-flop and enter fortune mark amplifying circuit and signal is amplified and the infrared signal beyond all controllers is filtered, through voltage comparator infrared signal is become standard 0--+5V square-wave signal again, by C
8, R
9Charge-discharge circuit makes the infrared multiple-pulse modulation signal that receives become single pulse signal, is the clock signal of d type flip flop, by d type flip flop output resistance R
10Driving the bidirectional triode thyristor pipe makes it with load conducting or disconnection.
The utility model has following advantage compared with the prior art:
1, existing infrared remote control switch, all must carry remote control transmitter, need to be equipped with dry cell, the cost height uses inconvenience, and is inoperative to other remote control transmitters, the utility model need not to be equipped with special-purpose remote-control transmitting part, all types of Infrared remote controller can this remote control switch of normal remote control, makes its unlatching or closes, and has versatility.Therefore general remote control switch reduces nearly half cost, has also increased the function of existing remote control transmitter simultaneously, has satisfied people's consumer psychology.
2, infrared ray is linearly propagated because high directivity, therefore in same room several remote control switches of the same type is installed, and is using the Infrared remote controller remote-controlled power switch, makes its unlatching or when closing, and does not interfere with each other.
3, the power unit of existing remote controller generally adopts civil power rectification behind electric resistance partial pressure to produce low-voltage DC and gives circuit supply.Therefore this class power supply self power loss is bigger, generally about 1-2 watt.And the employing of the power unit of this infrared remote control switch is minimum through the idle power consumption of capacitor charge and discharge formula rectification circuit with civil power, and Overall Power Consumption is about 0.05 watt, and power consumption differs 20 times, and prolonged application is saved appreciable electric energy.
