Temperature controller 25 is placed on the lateral wall of Water heating bucket 6.
The course of work:
1, when in the Water heating bucket 6 when anhydrous: turn on the power switch S, the bright diode of power supply and insulation indication 20 is bright, and at this moment, triode BG is in cut-off state, not conducting.Water heating bucket ball float 9 is pressed onto Water heating bucket and recovers water inlet switch 18, + 12V voltage recovers water inlet switch 18 by Water heating bucket and gives the coil power supply of the 1st single-pole double throw relay J 1, make its adhesive, the normally opened contact E2 of the 1st single-pole double throw relay J 1, movable contact E1 are 5 power supplies of cold water magnetic valve, cold water magnetic valve 5 is opened, and cold water enters Water heating bucket 6 from cold water bucket 1; At this moment, the voltage of coil one end of the 2nd single-pole double throw relay J 2 also is 12V, but because triode BG is in cut-off state, not conducting, the coil no current of the 2nd single-pole double throw relay J 2 flows through, the movable contact F1 of the 2nd single-pole double throw relay J 2 connects normally-closed contact F3, i.e. ground connection; The voltage at the coil two ends of the 4th single-pole double throw relay J 4 is 12V, and the coil of the 4th single-pole double throw relay J 4 is not worked yet, and movable contact L1 connects normally-closed contact L3, i.e. ground connection; The equal ground connection in coil two ends of the 3rd single-pole double throw relay J 3, the coil of the 3rd single-pole double throw relay J 3 is not worked yet, and movable contact H1 meets normally-closed contact H3, and promptly sky connects, so do not heat up water.
2, when the water level in the Water heating bucket 6 rises to assigned address, Water heating bucket ball float 9 touches Water heating bucket and stops water inlet switch 7, makes the coil blackout of the 1st single-pole double throw relay J 1, and cold water magnetic valve 5 also cuts off the power supply, and stops into water.Meanwhile, the coil one end ground connection of the 2nd single-pole double throw relay J 2, triode BG still is in cut-off state, not conducting, and the movable contact F1 of the 2nd single-pole double throw relay J 2 still connects normally-closed contact F3, i.e. ground connection; And the voltage difference at the coil two ends of the 4th single-pole double throw relay J 4 is 12V, the coil of the 4th single-pole double throw relay J 4 gets electric and adhesive, movable contact L1 switching normally opened contact L2,12V voltage is through meeting normally opened contact L2, movable contact L1, the coil of the 3rd single-pole double throw relay J 3 is to movable contact F1, the coil of the 3rd single-pole double throw relay J 3 gets electric and adhesive, movable contact H1 switching normally opened contact H2, trigger controllable silicon KG, make controllable silicon KG conducting, 220V voltage is connected at the two ends of electrothermal tube 8, begin to heat up water, the indication bright diode 21 of heating up water is bright, and power supply and the bright diode 20 of insulation indication extinguish.
3, when water temperature is raised to 100 when spending, temperature controller 25 disconnects, make triode BG transfer conducting state to by cut-off state, the collector voltage of triode BG is 12V, coil blackout because of the 1st single-pole double throw relay J 1, movable contact E1 is ground connection still, the coil of the 2nd single-pole double throw relay J 2 gets electric and adhesive, and movable contact F1 switching normally opened contact F2 connects+12V voltage, at this moment boiling water magnetic valve 11 work, boiling water in the Water heating bucket 6 flow to heat-preserving container 13, and heat-preserving container ball float 16 begins to move up, the coil of the 4th single-pole double throw relay J 4 still electric and adhesive, movable contact L1 switching normally opened contact L2, the voltage at the coil two ends of the 3rd single-pole double throw relay J 3 is 12V, and the coil 3 of the 3rd single-pole double throw relay J 3 is not worked yet, movable contact H1 switching normally-closed contact H3, promptly connect sky, controllable silicon KG is ended, and electrothermal tube 8 outages stop to heat up water, the bright diode 21 of indication of heating up water extinguishes, and the bright diode of power supply and insulation indication 20 is bright.
Afterflow effect because of the 5th resistance R 5, even temperature controller 25 has become conducting again, make triode BG transfer cut-off state to by conducting state, the collector voltage of triode BG still is 12V, so coil of the 2nd single-pole double throw relay J 2, the coil of the 4th single-pole double throw relay J 4 all still electric and adhesive, the voltage at the coil two ends of the 3rd single-pole double throw relay J 3 is 12V, the coil 3 of the 3rd single-pole double throw relay J 3 is not still worked, till boiling water in Water heating bucket 6 has been put, at this moment, heat-preserving container ball float 16 in the heat-preserving container 13 moves up, just in time touch the heat-preserving container that is under the normally off and stop water inlet switch 14, make heat-preserving container stop water inlet switch 14 and disconnect, boiling water magnetic valve 11 quits work; And Water heating bucket ball float 9 moves down always, recovers water inlet switch 18 up to being pressed onto Water heating bucket, makes the coil of the 1st single-pole double throw relay J 1 get electric and adhesive, the working cycles that water has been put in the next water inlet of beginning--heating up water--.
4, the effect of power reset button 22 is: when running into power failure or power supply loose contact, water in the Water heating bucket 6 does not advance full, click power reset button 22, give the coil power supply of the 1st single-pole double throw relay J 1, make its adhesive, + 12V voltage is by the normally opened contact E2 of the 1st single-pole double throw relay J 1, movable contact E1 is 5 power supplies of cold water magnetic valve, cold water magnetic valve 5 is opened, so that the water level in the Water heating bucket 6 rises to assigned address, Water heating bucket ball float 9 touches the coil blackout that Water heating bucket stops water inlet switch 7 backs the 1st single-pole double throw relay J 1, cold water magnetic valve 5 also cuts off the power supply, and stops into water.
5, boiling water is drunk the effect of toggle switch 23 and is: boiling water is drunk toggle switch 23 and is in normally closed position when working at ordinary times or automatically, only when wanting to drink just boiled boiling water, could shift to an earlier date (heating up water when indicating bright diode 21 bright) and stir this button, adorn behind the boiling water it group is pressed back to open position.
