Abstract
The invention discloses a device and method based on intelligent water temperature control of a water heater and water conservation design of an outer pipeline. By selecting a conducting channel of a three-way spherical valve, cold water in the pipeline is stored to be reused. A man-machine channel is designed to replace a mechanical valve and the temperature of the output water is simpler and more accurate to be adjusted through a fuzzy control method. Because a man-machine keyboard is utilized, the trouble of frequent adjusting is avoided compared with the mechanical valve and the problem of burning caused by excessively adjusting a hot water valve is also solved.

(4) after water heater is used to complete, press STOP key valve-off, close water heater.
Further, described single-chip microcomputer compares according to this temperature button default temperature and the detected temperature of temperature sensor, the PWM ripple of output different duty is specially: detect actual temperature at delivery port, obtain a difference with the contrast of requirement temperature, when difference〉15 when spending, be set to honest; 5＜difference＜15, big for hitting exactly; 0＜difference＜5 are for just little big;-5＜difference＜0 is for negative little big;-15＜difference＜-5 are for big in negative; Difference＜-15 are big for bearing, respectively the PWM ripple of corresponding different duty.
The invention has the beneficial effects as follows that the present invention stores ducted cold water again and utilizes by selecting the conductive channel of tee ball valve.And design man-machine passage, replace machinery valve,, adjust coolant-temperature gage more simply, accurately by the method for fuzzy control.Because we have used man-machine keyboard, with respect to machinery valve, removed the trouble of regulating back and forth from, also solved the problem that hot water valve is regulated excessive burn.
Description of drawings
Fig. 1 is the structured flowchart of the device of invention;
Fig. 2 is a schematic diagram of the present invention;
Fig. 3 is a program flow diagram.
The specific embodiment
As shown in Figure 2, be the schematic diagram of whole system, can simply find out the function that will realize from this figure: open
When moving water heater, the moving steering wheel of PWM wavestrip that single-chip microcomputer is exported certain dutycycle makes the conducting of tee ball valve water-saving pipeline, the processing of economizing on water; Cold water flows to end the back single-chip microcomputer and exports the moving steering wheel of PWM wavestrip of another dutycycle and make the tee ball valve delivery port logical in the water-saving pipeline, goes out hot water.When detecting water temperature greater than the temperature value set, single-chip microcomputer output PWM ripple reduces the size of hot water water intaking valve; When detecting water temperature less than the temperature value set, single-chip microcomputer output PWM ripple increases the size of hot water water intaking valve, and is constant to regulate water temperature.
As shown in Figure 1, the device that the present invention is based on water heater intelligent water temperature control and Outer Tube water-saving design comprises: single-chip microcomputer, temperature measuring circuit, signal amplification circuit, A/D change-over circuit, tee ball valve, steering wheel, magnetic valve, man-machine interface and LCD display; Wherein, temperature measuring circuit, signal amplification circuit and A/D change-over circuit link to each other successively, and tee ball valve links to each other with steering wheel, and A/D change-over circuit, steering wheel, magnetic valve, man-machine interface, LCD display link to each other with single-chip microcomputer respectively.
