Abstract
The invention discloses an outlet-water constant temperature control system of a solar water heater in the field of solar water heaters. The outlet-water constant temperature control system comprises a temperature detection module arranged at a water outlet, the signal output end of the temperature detection module is connected with the signal input end of a single chip microcomputer, the signal input end of the single chip microcomputer is further connected with the signal output end of a temperature setting unit, and the signal output end of the single chip microcomputer is respectively connected with the signal input end of a cold water electromagnetic valve, and the signal input end of a hot water electromagnetic valve and the signal input end of an alarm circuit. The outlet-water constant temperature control system controls dynamic adjustment of the switching-on time of the cold water electromagnetic valve and the switching-on time of the hot water electromagnetic time in a pulse width modulation mode, and flow regulation of cold water and hot water is achieved for a long time. Because the cold water and the hot water entering the system are discontinuous, the system needs a certain amount of space to mix the cold water and the hot water, so that warm water at a constant temperature is obtained. Thus, under the condition that the constant temperature of the outlet water is guaranteed, energy is saved, and the outlet-water constant temperature control system can be used for outlet water temperature adjustment of the solar water heater.
Description
Technical field
The present invention relates to a kind of water heater, particularly a kind of solar water heater.
Background technology
Solar water heater, as a kind of mode of using energy source, has advantages of safety economy, energy-conserving and environment-protective, thereby is used widely.During its use, often need first manually to regulate temperature and re-use, but in use, often can need manual adjustments again because of the variation of hot water or cold water's temperature and pressure, so both inconvenience, can cause again the waste of water resource.
Existing scheme is generally the water temperature regulating in solar water heater water tank, obtains the constant temperature of delivery port.When temperature is lower in water tank, with Electric heating, water is heated to design temperature, and temperature is when high or convert cold water or helpless.This is both unnecessary under many circumstances, causes again waste.
Summary of the invention
The problem that the object of the invention is to cause for solar water heater water outlet thermostatic control mode of the prior art energy waste, provides a kind of solar water heater water outlet thermostatic control system, having guaranteed under the condition of water termostat, has saved the energy.
The object of the present invention is achieved like this: a kind of solar water heater water outlet thermostatic control system, comprise the temperature detecting module that is arranged on water outlet, the signal output part of described temperature detecting module is connected with the signal input part of single-chip microcomputer, the signal input part of described single-chip microcomputer is also connected with the signal output part of Temperature Setting unit, and the signal output part of described single-chip microcomputer is connected with respectively the signal input part of the signal input part of cold water magnetic valve, hot water electromagnetic valve's signal input part and warning circuit.
As a further improvement on the present invention, described single-chip microcomputer is selected AT89C2051 chip.
As a further improvement on the present invention, described temperature detecting module is selected the DS18B20 digital temperature sensor of DALLAS company.
When the present invention works, temperature detecting module sends to single-chip microcomputer by the water temperature signal of water outlet, single-chip microcomputer contrasts the water temperature signal of this signal and the setting of Temperature Setting unit, if the temperature of water outlet is higher than design temperature, single-chip microcomputer transmits control signal to cold water magnetic valve, control cold water magnetic valve and add water in water tank, with in reaching and the effect of water temperature, if the temperature of water outlet is lower than design temperature, single-chip microcomputer transmits control signal to hot water electromagnetic valve, control hot water electromagnetic valve toward heating water in water tank, with in reaching and the effect of water temperature, compared with prior art, beneficial effect of the present invention is: single-chip microcomputer send hot and cold water magnetic valve PWM driving pulse according to the comparison that is leaving water temperature and user's design temperature, with pulse width modulation, dynamically adjust cold, hot water electromagnetic valve's ON time, realize in a long time cold, hot water flow regulates.Because the hot water or cold water of the system of entering is interrupted, system needs certain space carry out hot water or cold water's mixing, to obtain the warm water of constant temperature, thereby having guaranteed under the condition of water termostat, has saved the energy.The present invention can be used in the adjusting of solar water heater leaving water temperature.
Accompanying drawing explanation
Fig. 1 is control principle block diagram of the present invention.
The specific embodiment
A kind of solar water heater water outlet thermostatic control system as shown in Figure 1, comprise the temperature detecting module that is arranged on water outlet, the signal output part of temperature detecting module is connected with the signal input part of single-chip microcomputer, the signal input part of single-chip microcomputer is also connected with the signal output part of Temperature Setting unit, the signal output part of single-chip microcomputer is connected with respectively the signal input part of cold water magnetic valve, hot water electromagnetic valve's signal input part and the signal input part of warning circuit, single-chip microcomputer is selected AT89C2051 chip, temperature detecting module is selected the DS18B20 digital temperature sensor of DALLAS company.
When the present invention works, temperature detecting module sends to single-chip microcomputer by the water temperature signal of water outlet, single-chip microcomputer contrasts the water temperature signal of this signal and the setting of Temperature Setting unit, if the temperature of water outlet is higher than design temperature, single-chip microcomputer transmits control signal to cold water magnetic valve, control cold water magnetic valve and add water in water tank, with in reaching and the effect of water temperature, if the temperature of water outlet is lower than design temperature, single-chip microcomputer transmits control signal to hot water electromagnetic valve, control hot water electromagnetic valve toward heating water in water tank, with in reaching and the effect of water temperature, single-chip microcomputer send hot and cold water magnetic valve PWM driving pulse according to the comparison that is leaving water temperature and user's design temperature, with pulse width modulation, dynamically adjust cold, hot water electromagnetic valve's ON time, realize in a long time cold, hot water flow regulates.Because the hot water or cold water of the system of entering is interrupted, system needs certain space carry out hot water or cold water's mixing, to obtain the warm water of constant temperature, thereby having guaranteed under the condition of water termostat, has saved the energy.
