Domestic gas water heater has many advantages, such as heating rapidly, and water yield is big.Existing constant temp gas water heater is adopted
It is all the principle of control temperature of proportional valve.String has a flow sensor in the pipeline of this water heater.Combustion gas valve is one
Electric control valve (i.e. proportioning valve).Water flow is converted to corresponding electric signal and will by combustion type Thermostatic water heaters flow sensor
This signal input controller.Controller adjusts air valve opening according to the intensity of input signal or frequency, makes gas flow and water
The proportional variation of flow, to achieve the purpose that constant water temperature.When water heater working, flow sensor can perceive water flow
Size, signal is transferred to proportioning valve, controlled by him fire row number, and then control firepower size, adjust water temperature.But by
In the limitation of the rigid condition of heating method, common constant temp gas water heater may be subjected to hydraulic pressure, air pressure in use
It is unstable and influence leaving water temperature, the difference of originally set temperature and leaving water temperature 1-6 degree is caused, and then people is allowed to feel to have a bath not
Comfortable water temperature is non-constant.
Accurate constant temp gas water heater increases water servomechanism on the basis of its common constant temp gas water heater, thus
Set temperature and leaving water temperature difference are reduced, but electronic gas water heater proportioning valve and water servomechanism after all, is machine
Tool component or electric-controlled mechanical component, movement are required to the time, can not far make up the unstable variation of hydraulic pressure, air pressure and bring
The variation of leaving water temperature.
Gas heater is all made of segmented burning, but segmented combustion bin limited amount after all, when inflow temperature exceeds
Certain numerical value is formed pain spot when controllably minimum fuel value is not able to satisfy the setting temperature of user demand to gas heater.
Fast-type electric water heater, electric heater are mounted in volume very little shell, and tap water is heated by electric heater
Obtain hot water, have it is small in size, heating rapidly, temperature controls accurate advantage, but the hot device of the electric heater for reaching this effect
Due to being limited by user power utilization environment, general water yield is difficult to match in excellence or beauty with combustion gas.
Innovation and creation content
The object of the present invention is to provide a kind of novel combustion gas and electric heating combined type water heater --- combustion electric heater, it will
Gas heater and fast-type electric water heater combine, to solve gas heater set temperature and leaving water temperature difference compared with
Greatly, temperature stability is not high；Fast-type electric water heater water yield is small, to the demanding pain spot of electric condition.
The purpose of the present invention can be achieved through the following technical solutions:
Electric heater is fired, the gas heating system and be precisely controlled to hot water temperature that section at the beginning of comprising providing hot water heats
Electric heating system, the two is installed in series inside water heater housing, heated by central controller controls.
The combustion electric water heater inlet mouth is equipped with flow sensor, inflow temperature sensor；
Medium temperature sensor is housed between the combustion electric heater gas heating system and electric heating system water route
The water outlet of gas heating system is connected with the water inlet of electric heating system.
The central controller calculates control gas heating system by PID and electric heating system coordinates heating.
After tap water enters gas heating system by water feeding of heater mouth, gas heating system exists as main heating system
Coarse adjustment heating is carried out to it, makes water temperature to close to user setting temperature；Central controller passes through medium temperature sensor, out water temperature
The collected real time data of sensor is spent, carries out PID calculating with user setting temperature, so that controlling electric heating system carries out hot water
Fine tuning.
The power used under the power water flow stable case of electric heating system is the half of rated power, become larger when water flow or
When gaseous-pressure becomes smaller, while gas heating system adjusts heating, electric heating system increases power, water temperature for stablizing
Degree；When water flow becomes smaller or gaseous-pressure becomes larger, while gas heating system adjusts heating, electric heating system reduces power,
For stablizing leaving water temperature.
When inflow temperature is higher, central controller calculates gas heating system and is adjusted to minimum controlled power, can still make
When leaving water temperature is higher than setting temperature, then gas heating system stops heating, provides heated at constant temperature by electric heating system completely.
It is characterized by: gas heating system is as main heating system, water inlet is equipped with flow sensor, water outlet with
The water inlet of electric heating system as auxiliary heating is connected；In being equipped between gas heating system and electric heating system water route
Between temperature sensor；Central controller calculates control gas heating system by PID by inflow, water temperature, user setting temperature
System and electric heating system coordinate heating.
