Abstract
The utility model provides a kind of boiling water dechlorination control circuit, comprise single-chip microcomputer, it is characterized in that: described single-chip microcomputer connects temperature controller switch box relay, described temperature controller switch serial connection heating element one, described heating element connects heating element two in the lump, described heating element two be serially connected with described relay with the use of relay switch.The utility model can automatically realize switching to low-power to heat a period of time by high power after water boiling, and is finally auto-breaking.Can accomplish more thoroughly to dechlorinate, complete Automatic control of single chip microcomputer can be realized again, without the need to manual operation, really realize intellectuality.
Description
Technical field
The utility model relates to field of electric control, specifically, relates to a kind of boiling water dechlorination control circuit.
Background technology
The electric heating pot of existing sale has two classes on the market, auto-breaking after being water boiling; Two is can be incubated a few minutes after boiling.And the electric heating pot more thoroughly will removing chlorine needs can to change into after water boiling low-power well heater and to keep after heated condition a few minutes auto-breaking again.The shortcoming of prior art be water once boiling auto-breaking, fluidized state a period of time can not be kept, thus more chlorine can be remained.
Summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of boiling water dechlorination control circuit, thoroughly dechlorinates, controls full automation.
The utility model adopts following technical scheme to realize goal of the invention:
A kind of boiling water dechlorination control circuit, comprise single-chip microcomputer, it is characterized in that: described single-chip microcomputer connects temperature controller switch box relay, described temperature controller switch serial connection heating element one, described heating element connects heating element two in the lump, described heating element two be serially connected with described relay with the use of relay switch.
As the further restriction to the technical program, described single-chip microcomputer adopts STC89C51 chip, and the pin P3.0 of described single-chip microcomputer connects described temperature controller switch, and the pin P2.0 of described single-chip microcomputer connects described relay, and described single-chip microcomputer connects crystal oscillating circuit.
As the further restriction to the technical program, described heating element one two ends also meet burner on light and resistance R1, and described heating element two two ends are also connected to dechlorination pilot lamp and resistance R2.
As the further restriction to the technical program, described single-chip microcomputer is connected 5V power supply by electric capacity C with gauge tap.
Compared with prior art, advantage of the present utility model and good effect are: the utility model adopts heating element one for water normal heating, when after water boiling, temperature controller switch because the principle of expanding with heat and contract with cold is opened, thus gives single-chip microcomputer input high level, after single-chip microcomputer receives high level signal, pilot relay adhesive, thus making heating element two work, after heating element two gives the boiling water heating setpoint time, relay disconnects automatically, thus quits work.The utility model can automatically realize switching to low-power to heat a period of time by high power after water boiling, and is finally auto-breaking.Can accomplish more thoroughly to dechlorinate, complete Automatic control of single chip microcomputer can be realized again, without the need to manual operation, really realize intellectuality.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
In figure, U, single-chip microcomputer, K1, temperature controller switch, L1, heating element one, L2, heating element two, K relay, M1, burner on light, M2, dechlorination pilot lamp, K2, gauge tap, T, crystal oscillating circuit.
Embodiment:
Below in conjunction with embodiment, further illustrate the utility model.
See Fig. 1, the utility model comprises single-chip microcomputer U, described single-chip microcomputer U connects temperature controller switch K1 and relay K, described temperature controller switch serial connection heating element one L1, described heating element one L1 also meets heating element two L2, described heating element two L2 be serially connected with described relay K with the use of relay switch.
Described single-chip microcomputer adopts STC89C51 chip, and the pin P3.0 of described single-chip microcomputer connects described temperature controller switch K1, and the pin P2.0 of described single-chip microcomputer connects described relay, and described single-chip microcomputer connects crystal oscillating circuit T.
Described heating element one L1 two ends also meet burner on light M1 and resistance R1, and described heating element two L2 two ends are also connected to dechlorination pilot lamp and resistance R2.
Described single-chip microcomputer is connected 5V power supply by electric capacity C with gauge tap.
The power of heating element one L1 of the present utility model is 1800W, the power of heating element two L2 is 500W, when after water ebuillition of heated, temperature controller switch K1 acts on because bimetallic strip expands with heat and contract with cold and automatically opening, thus make the single-chip microcomputer P3.0 pin be attached thereto reach high level 1, first JNB P3.0 instruction is used in Single Chip Microcomputer (SCM) program, namely when P3.0 is low level, (temperature controller switch K1 closes, heating element one L1 normally works) original place wait, only have when after water ebuillition of heated, temperature controller switch K1 opens i.e. P3.0 automatically when being also 1, program is just run downwards.Low-power heating element two work is made by single-chip microcomputer P2.0 pin pilot relay K adhesive, then delay procedure (time can be selected: 1 minute or 2 minutes etc.) is called, the last pilot relay K again of program disconnects and makes low-power heating element two power-off, thus quits work.It should be noted that in addition, when electric kettle does not use, preferably gauge tap K2 is closed, prevent single-chip microcomputer U from consuming electric energy.
