Description
The utility model relates to a kind of multifunction remote-control regulator, belongs to household electrical appliance technical field.
The present employed power supply of household electrical appliance, as illuminating lamp, desk lamp, electric heating appliance etc., its AC power is switch on the spot generally, can not step-less adjustment voltage, and this local operation Switching Power Supply, owing to use the band contact switch, make and break contact is influenced by the frequency of utilization of load current, and useful life is short, needs often maintenance, less economical, nor safety.Particularly illuminating lamp usually needs lighting in the dark, inconvenient operation.The remote circuit of present industrial application and remote control switch also are wired remote controls generally, and cost an arm and a leg, and can not promote the use of on the household electrical appliance.And this type of remote circuit generally do not have the stepless voltage regulation function yet, and to the frequent load that needs to change voltage, using has limitation.In addition, household electrical appliance remote circuit adjusting devices such as existing television set, electric fan mostly adopt infrared emission and reception, the direction that during use emission is received requires high, can not have the obstacle object to block between reflector and the receiver, receiving range is also short, uses inconvenient.
The purpose of this utility model is a kind of remote control that adopts amplitude-modulated wave to transmit and receive of design, makes the non-directional requirement of control, even have object to block between reflector and the receiver, still can regulate control, and command range can reach about 20 meters or which floor floor.
Content of the present utility model is the multifunction remote-control regulator, comprises reflector and receiver two parts.Reflector is a control end, and receiver is connected with load.Reflector mainly is made up of high frequency oscillation unit and control voltage cell.Receiver mainly by frequency-selecting, height put, resonance and control circuit form.
