Abstract
The utility model discloses a bowl washing machine control device with a night electric key, which belongs to the application technique of a single chip computer. The utility model is mainly characterized in that an hour setting key, a minute setting key and a night electric key are arranged in a dishwasher control circuit, and are respectively connected with the I/O input port of the single chip computer, the I/O input port of the single chip computer is connected with a switch circuit which is connected with a switch executive circuit, and a normally open contact of the switch executive circuit is connected with a dishwasher power supply. A clock display circuit is connected with the I/O input port of the single chip computer. The utility model makes a dishwasher which is not provided with the night electric key be provided with a night electricity setting function for the convenience of the work of the dishwasher with night electricity, 50 percents of the electricity cost is saved, the valley electricity is thoroughly used, and the electric force resource is saved.
Description
Technical field the utility model belongs to the single-chip microcomputer applied technical field.
Before background technology the utility model applying date, dish-washing machine is not provided with the night letter key, and it is the period work of paddy electricity in the night letter period automatically that dish-washing machine is not had, and uses the paddy electricity to make troubles for the user that the peak valley ammeter is housed.
The summary of the invention the purpose of this utility model is exactly to overcome dish-washing machine can't use the paddy disadvantage of electricity period automatically, a kind of device that dish-washing machine is worked in the paddy electricity period automatically is provided, the user that the peak valley ammeter is housed is brought convenience and save the electricity charge, national grid is then improved the utilization rate of using electric resources.Dish-washing machine control device with night letter key of the present utility model is suitable for all kinds of monolithic processor controlled dish-washing machine control device.The technical scheme that its technical problem that solves the utility model adopts is: hour, minute are set in the dish-washing machine control circuit key and night letter key are set, be connected with the single-chip processor i/o input port respectively, the single-chip processor i/o output port connects on-off circuit, on-off circuit connects the switch executive circuit, and the normally opened contact of switch executive circuit connects the dish-washing machine power supply.
Description of drawings Fig. 1 is a circuit block diagram of the present utility model.Among the figure 1 for single-chip microcomputer, 2 promptly key 3 is set is the night letter key hour, minute for function key, 4 is display circuit, 5 is on-off circuit, 6 is power supply.
Fig. 2 is an electrical schematic diagram of the present utility model.PIC16C57 is a single-chip microcomputer among the figure, K
1Be a hour key, K
2Be a minute key, K is the night letter key.9013 is switching tube, and J is a relay, and LCD or LED are display screen, and T is a power transformer, D
1～D
4Be rectifying tube, 7805 is voltage-stabiliser tube.
Specific embodiment the utility model is provided with a hour key K in the dish-washing machine control circuit
1, minute key K
2And night letter key K, be connected with the I/O input of single-chip microcomputer respectively.In the present embodiment, single-chip microcomputer is PIC16C57, and the base stage of I/O output merchant the eleventh of the twelve Earthly Branches switching tube 9013 of single-chip microcomputer is connected, and I/O output high level or low level make 9013 switching tube conductings and end.The colelctor electrode of switching tube 9013 is connected with the coil of executive circuit relay J, and 9013 conductings make the relay adhesive; Otherwise, cut-off; The normally opened contact of relay links to each other with the live wire of dish-washing machine power supply, the break-make of control live wire.When 9013 conductings, the relay adhesive, the normally opened contact adhesive makes the live wire conducting, dishwasher into operation, on the contrary dish-washing machine is not worked.The built-in control software of single-chip microcomputer, after pressing the night letter key, according to the paddy set the electricity period be the 22:00-6:00 self-opening power supply, the paddy electricity period also can be provided with voluntarily by a hour key, a minute key.Display circuit is that the LCD liquid-display screen also can be the LED charactron, is driven by single-chip microcomputer or drive circuit.Power circuit passes through transformer T through D by civil power
1～D
4Rectification circuit and voltage-stabiliser tube 7805 voltage stabilizings becoming 5V dc source.The related single-chip microcomputer of the utility model can be shared with the mcu resource of dish-washing machine control circuit.
