Description

Multi-functional timer

The utility model is a kind of multi-functional timer, belongs to the timing controlled technical field.

At present, some large household appliances---as electronic disinfector, washing machine etc. time cycle controller is installed all, but its function is too simple, function is perfect inadequately, and not product independently, can not be applied on all household electrical appliance and carry out timing controlled, a kind of can the cooperation carry out time-controlled multi-functional timer with all household electrical appliance and be starved of in people's daily life.

The purpose of this utility model is exactly independence not to be arranged as yet and the timer product of perfect in shape and function at present in order to solve, and a kind of perfect in shape and function of research and design, the multi-functional timer that can cooperate with all household electrical appliance are to satisfy the needs of people's daily life.

The utility model is realized by following structure technology scheme: the structural representation of multi-functional timer as shown in Figure 1, it is by casing 1, printed circuit board (PCB) 2, trigger button 3,9, button cell 4,10, LCD 5,11, switching time and standard time are regulated button 6,12, regulative mode button 7,13, attaching plug 8, socket 14 connects and composes jointly, its interconnected relationship is: printed circuit board (PCB) 2 is installed in the casing 1, button cell 4,10 are loaded in the battery folder respectively, LCD 5,11 are installed in machine shell panel top and by the electronic timer chip IC 1 on lead and the printed circuit board (PCB), IC2 is connected, trigger button 3,9, switching time and standard time are regulated button 6,12, regulative mode button 7, below 13 displays that are installed on respectively on the machine shell panel and by the IC1 on lead and the printed circuit board (PCB), IC2 is connected, attaching plug 8 is connected with the printed circuit board power end by lead, and socket 14 is connected with printed circuit board (PCB) by lead; Wherein, its circuit frame principle figure as shown in Figure 2, it is by power circuit 15, trigger button 3,9, electronic timer chip 16,17, voltage amplifier 18,19, trigger 20, solid-state relay 21 is electrically connected formation jointly, its interconnected relationship is: power circuit is by deposited copper sheet or the lead and the triggering button 3 of printed circuit board (PCB), 9, voltage amplifier 18,19 and trigger 20 be connected, triggering button is connected with circuit board with lead, electronic timer chip 16,17 pass through resistance respectively, electric capacity and deposited copper sheet and voltage amplifier 18,19 are connected, voltage amplifier 18,19 pass through resistance respectively, electric capacity and deposited copper film are connected with trigger 20, trigger 20 reaches deposited copper film by resistance or lead is connected with solid-state relay 21, and solid-state relay 21 is connected with socket 14 by resistance and lead.Its principle of work is as follows: power circuit can become the 12V direct supply with alternating current 220V rectifying and wave-filtering, voltage stabilizing, when setting-up time (a certain switching time and the standard time of setting are poor) arrives, electronic timer chip (as SK-280) sends electric signal automatically, this signal removes to trigger trigger after amplifying through voltage amplifier, trigger is exported high level or low level according to different input signals, when trigger output high level, the solid-state relay contact sets is connected, thereby the household electrical appliance power supply is connected; When the trigger output low level, the solid-state relay contact sets disconnects, thereby the household electrical appliance power supply is disconnected.The effect that triggers button is to produce trigger pip by pressing keys and dividing potential drop, triggers trigger immediately, thus the break-make of control household electrical appliance power supply, and it is not subjected to electronic timer chip (as SK-280) to set the influence of time and the existing state of trigger.The circuit theory diagrams of one of embodiment as shown in Figure 3, wherein: power circuit 15 is connected and composed by voltage stabilizing diode D1, commutation diode D2, capacitor C 1～C2 connection in series-parallel, triggering button is connected and composed by button N1, N2, resistance R 9～R12 connection in series-parallel, voltage amplifier is connected and composed by integration member IC3, resistance R 1～R8, capacitor C 3～C4 parallel-series, trigger is electrically connected and is constituted by integration member IC4, resistance R 13, and solid-state relay comprises relay contact group J _1-1, J _1-2

The utility model compared with prior art has following advantage and beneficial effect: 1. this timer has multiple timing function, comprise: energy special time (promptly switching time and the standard time of regulating in advance is poor) energized, special time (switching time and the standard time that are another setting are poor) deenergization; Can special time energized, deenergization of arbitrary moment (i.e. certain switching time of She Dinging or moment of pushing the triggering button); The arbitrary moment energized of energy, the special time deenergization; The arbitrary moment energized of energy, arbitrary moment deenergization; 2. this multi-functional timer is easy to use, almost can be used with all household electrical appliance, when cooperating the just time spent with illuminating lamps such as electric light, light pipes, can timing automatic turn on light, turn off the light, and also can turn on light at any time, turn off the light; When with televisor, radio cassette player, video recorder, electric fan, when air conditioner is used, can realize timing automatic start, shutdown or start shooting at any time, shut down; When being used with electric cooker, can be under the situation that nobody looks after regularly finish cook, housework such as Baoshang; 3. the power consumption of this multi-functional timer own is minimum, if meet situation about having a power failure, after powering again, it is regularly still effective.
