The utility model has the advantages of fast water temperature governing response and no hysteresis, has the capability of stable indoor temperature regulation, obvious effect of energy saving and lower cost, versatility, and can greatly reduce the heating gas quantity of a boiler.
Description
The utility model relates to the domestic gas boiler to provide hot water and heat fuzzy controller that a kind of each door type is installed.
The thermal source of heating system that with the family is unit is from the combustion gas miniature boiler.This boiler erection is convenient, operation is simple, and is pollution-free to the room, and can adjust and control according to the different instructions for use in each family, reaches energy-efficient purpose.A common gas fired-boiler also will be the indoor domestic hot-water that kitchen, toilet are provided except that heating.Existing gas boiler to provide hot water and heat controller circuitry complexity, it is big to produce debugging work load, and control accuracy is not high, and dynamic characteristic is undesirable, and the PID adjusting of adopting routine more, and the control and regulation large time delay problem to room temperature is difficult to solve always like this.Existing in addition controller generally can not be applicable to the gas-fired water heating boiler of various models, and energy-saving effect is not good.
The purpose of this utility model is to provide a kind of gas boiler to provide hot water and heat fuzzy controller, its water temperature governing response rapidly, do not lag behind does not have stable indoor temperature regulating power and considerable energy saving effect, can reduce the gas quantity of boiler greatly, cost is lower, and has versatility.
The purpose of this utility model is achieved in that a kind of gas boiler to provide hot water and heat fuzzy controller, it comprises central controller CPU, the input of this central controller picks out water temperature sensor, indoor temperature transmitter, temperature setting input and water-control switch signal, the output of central controller connects gas control valve and blower voltage control end by executing agency, and the input of wherein said CPU also is connected to the return water temperature sensor output signal that is installed in as on the indoor water return pipeline of load.
Described CPU is connected to the cpu signal latch cicuit, and this circuit connects triode by the latch of input contact firearm ignition signal and fan operation signal and forms.
Described CPU is connected to the flue gas sensor signal that is arranged in the flue.
Described CPU is connected to the outdoor temperature sensor signal.
According to the technique scheme analysis as can be known, the utility model guarantees that by latch cicuit the action of CPU is safe and reliable, set out water temperature sensor and the return water temperature sensor is set on water return pipeline and forms inside and outside two closed loop regulation circuit at pipe outlet, solved coolant controlled large time delay problem, ensured the fast-response of whole water route circulation, reached energy-conservation and comfortable purpose, and the utility model also have simple to operate, characteristic of strong applicability.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model principle of compositionality figure;
Fig. 2 is one of the utility model circuit theory diagrams;
Fig. 3 is two of the utility model circuit theory diagrams.
Referring to Fig. 1,2,3, the utility model is a kind of gas boiler to provide hot water and heat fuzzy controller, it comprises CPU IC2, and the input of CPUIC2 picks out the input of four temperature sensors: leaving water temperature sensor Vout, indoor temperature transmitter Vi, return water temperature sensor Vin and outdoor temperature sensor Vw.CPU mouth line also jointing temp is set input adjusting key UP1, UP2, DN1, DN2 and water-control switch signal K1, K2, also has panel-switch input signal TIMER, SET etc.Wherein the leaving water temperature sensor is installed on the hot water outlet pipeline, and the return water temperature sensor is installed on the indoor water return pipeline as load, thereby constitutes main feature-formations of the utility model pair closed-loop adjustment loops.CPU can be by the difference of leaving water temperature and return water temperature like this, and directly the response regulation variations in temperature is regulated water temperature automatically, solves the large time delay problem that water temperature is regulated, and has guaranteed the stability of temperature, has improved comfort level.For accessing, the variation relation between indoor temperature and the outdoor temperature satisfies the Optimal Control condition of fuzzy control, ensures the comfort of temperature better, also is connected to outdoor temperature sensor signal Vw on the mouth line of CPU.The input port line of CPU also is connected to ignition flame detection signal FIRI, heating type HTYPE, blower fan CRANK PULSES FANI.CPU IC2 output is controlled blower fan by the current negative feedback circuit of being made up of IC1C, triode T5 and resistance R 21, can change the wind speed of blower fan, to provide different air quantity at different gas quantities, satisfies high efficiency requirement.CPU is by current negative feedback circuit IC1D, triode T4, resistance R 14 control gas control valves, the power of regulating burner flame.The startup of the output signal PUMD of CPU, PUMC control pump, output signal FIRC, the igniting of FIRD control point firearm, output signal PWM controls Fan Regulation, and output also is connected to the burnt gas switch valve controling circuit of being made up of photocoupler OPT3, triode T3, relay J R2.
Because gas fired-boiler has comprised the magnetic valve of some frequent operations, and igniter, they often produce electromagnetic interference when action, and have a strong impact on the operate as normal of CPU, even cause the CPU confusion, for guaranteeing the safety of cpu data, need before igniting, latch some data, force CPU to be in reset mode, the wait igniting finishes and wakes CPU up work again.Therefore the utility model connects signal latch circuit at the mouth line of CPU.This circuit meets triode T9 by the latch IC3A of input contact firearm ignition signal and fan operation signal and forms.As igniter fire signal FIRC, when FIRD has output, the FIR end is high level, so the T9 conducting, the MCLR output low level, and cpu reset is preserved data; When FIR was low level, T9 ended, and MCLR exports high level, and CPU wakes work up.
In addition, be connected to the flue gas sensor signal that is arranged in the flue,, thereby cooperate the size of control gas valve and the rotating speed of blower fan so that can record the efficiency of combustion of combustion gas at CPU.
