Description

The multifunctional power timer

The utility model proposes the multi-functional timer of a kind of power supply, belong to electric field, is a kind of supply unit that can be subjected to time control switch automatically.

Existing many kinds of timers, for example: the noisy formula timer that shakes of mechanical clock, the photosensitive control type timer of mechanical clock pointer, electronic watch stroke signal timing device, signal timing device when electronic watch makes a noise, single-chip microcomputer programmable timer etc.These timers As time goes on, what have no longer includes use value, the deficiency that also exists self that has.

The mechanical clock timer is eliminated along with the development of electronic utility, and the electronic watch timer will draw the lead that connects mileometer adjustment and output signal in watch core, technology is difficult, and it is irregular to seem again, does not possess mass production conditions, and the watch core life-span is limited, and is malfunctioning easily, and is difficult to repair.The single-chip microcomputer programmable timer, complicated operation, loaded down with trivial details, common people are difficult for grasping, the cost height, some function also is not suitable for family expenses, therefore to promoting and brought in batches restriction.

The purpose of this utility model is to provide a kind of multifunctional power timer, and it is few to have components and parts, and circuit is simple and reliable, is easy to produce in batches.

Multifunctional power timer of the present utility model has power switch circuit and control circuit two parts, it is characterized in that control circuit is by D.C. regulated power supply, clock integrated package LMg364 or 8365 and peripheral crystal oscillating circuit, clock display, rest-set flip-flop (or JK flip-flop), d type flip flop, or door, driver and power switch relay are formed, locking output in 1 hour of clock integrated package connects the d type flip flop input end, 12 outputs of making a noise of making a noise connect two input ends of rest-set flip-flop respectively, and the output terminal of two triggers connects respectively or two input ends of door, or driver connected behind the door promotion power switch relay.

The utility model utilizes the clock integrated package LMg364 (or 8365) of up-to-date appearance to cooperate two triggers and one or a simple logical circuit of composition, realized the multifunctional power timer that open and close and 1 hour regularly open or close with minimum components and parts, and circuit is easy to produce in batches, reliably working over a long time.Circuit of the present utility model is simple, and cost is lower, and application is wider, can enter family, for huge numbers of families alleviate heavy housework intensity, has improved normal domestic use electrical equipment electricity consumption science, makes its use more convenient.

Fig. 1, the outside drawing of the utility model embodiment.

Fig. 2, the electrical schematic diagram of the utility model embodiment.

Embodiment of the present utility model as shown in Figure 1, 2.Referring to Fig. 2.Multifunctional power timer independent power source on-off circuit and control circuit two parts, power switch circuit is main by input current lead, relay and power supply output, a pair socket constitutes, control circuit is reached or a logical circuit of forming by stabilized voltage supply, clock integrated package LMg364 and peripheral crystal oscillating circuit thereof, display, rest-set flip-flop, d type flip flop, or driver behind the door promotes the power switch relay.

Referring to circle 1, Fig. 2.When this Power supply timer is plugged the 220V power supply, open the timer power supply switch, it is consistent with Beijing time to divide button H, M that the clock number tone of Chinese characters on the display is arrived with timing and accent, and this moment, the Q end of rest-set flip-flop and d type flip flop all was in low level " 0 " state.Open to give approximately and show logical switch, " 00:00 " appears in display, with timing and transfer the branch button with demonstration transfer to will energized the moment, and this switch cuts out; Open to give approximately and show " break " switch, " 00:00 " appears in display, with timing and accent branch button H, M with the demonstration time transfer to will deenergization the moment, and this switch cuts out.Display is got back to Beijing time.Walk the moment of opening approximately to giving when the display time, master chip LMg364 gives and opens output line 17 output high level " 1 " approximately, and rest-set flip-flop S end is high level " 1 ", and the R end is low level " 0 ", and the Q end is high level " 1 " by low level " 0 " upset.Or an output high level " 1 " makes the relay adhesive by driver, 220V power supply output seat of honour power connection, pair seat power supply disconnection.Walk the moment of closing approximately to giving when the display time, master chip gives and closes output line 42 output high level " 1 " approximately, rest-set flip-flop R end is high level " 1 ", the S end is low level " 0 ", the Q end is by the long-pending low level " 0 " that transfers to of high level " 1 ", or door output low level " 0 ", by driver relay is discharged, power supply output seat of honour power supply disconnects, and pays the seat power connection.

Give in about signal 24 hours being provided with arbitrarily, signal repeated automatically in per 24 hours, also can change setting at any time, and action is by the new operation that is provided with.

When opening routine timing limit switch, " 59 " countdown output line 15 output high level " 1 " appear in display, d type flip flop Q end is high level " 1 " by low level " 0 " upset, or door output high level " 1 ", pass through driver, relay gets electric adhesive, and the energising of the power supply output seat of honour is paid the seat power supply and disconnected.Display is successively decreased by ": 59 " per minute, until ": 00 " time, countdown output line 15 output low levels " 0 ", d type flip flop Q end is low level " D " by high level " 1 " upset, or door output low level " 0 ", and relay electric-loss discharges, the seat energising is paid in the outage of the power supply output seat of honour.

When opening 1 hour countdown limit switch, the display appearance ": 59 ", if when wishing that conduction time is shorter, divide a button M by downward modulation, then display is by ": 59 " when dropping to required time, release button, display promptly begins per minute thus the time and successively decreases, until ": 00 " time, the outage of the power supply seat of honour, it is logical to pay seated connection.

Countdown is opened the longest 59 minutes at every turn, the shortest transferring to 1 minute.

Advantage and good effect:

1. be home interior specially, cost is lower, day by day universal in view of electric cooker, air-conditioner, and this Power supply timer can To enter family, for huge numbers of families provide convenience, applied value is arranged, easily produce economic benefit.

2. control electric cooker, electric pot can give the approximately open and close time in advance, and control is cooked automatically, and can relievedly boil Congee, boil soup, need not worry it is boiled dry. Bring convenience to man and wife both employed, alleviated housework intensity.

3. control air-conditioning open and close automatically, can using electricity wisely, the user is saved worry.

4. easy and simple to handle, intuitive display is grasped easily.

5. circuit is simple, and totally digital circuit, reliable operation, regularly accurate are difficult for producing fault.
