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.
Utility model content
The purpose of the utility model is to provide a kind of novel combustion gas and electric heating combined type water heater --- combustion electric heater,
It combines gas heater and fast-type electric water heater, to solve gas heater set temperature and leaving water temperature difference
The not high problem of larger, temperature stability and fast-type electric water heater water yield it is small, to the demanding pain spot of electric condition.
The said effect of the utility model can be achieved through the following technical solutions: combustion electric heater, comprising providing hot water
The gas heating system of first section heating and the electric heating system being precisely controlled to hot water temperature, the two are installed in series in hot water
Device enclosure interior, is heated by central controller controls, it is characterised in that: the gas heating system is used for as main heating system
System, combustion electric water heater inlet mouth are equipped with flow sensor, combustion electric heater water outlet and the electric heating as auxiliary heating
The water inlet of system is connected；It is sensed between the gas heating system and the electric heating system water route equipped with medium temperature
Device；Gas heating system described in the central controller controls and the electric heating system coordinate heating.
Preferably, after tap water enters the gas heating system by the combustion electric water heater inlet mouth, the combustion
Gas heating system carries out coarse adjustment heating to it again as main heating system, makes water temperature to close to user setting temperature；The center
Controller is adopted by the medium temperature sensor and the leaving water temperature sensors being mounted on the combustion electric heater water outlet
The real time data collected carries out PID calculating with user setting temperature, so that controlling the electric heating system carries out hot water fine tuning.
Preferably, the power of electric heating system reserved part power in waterflow stabilization is used as more than fine tuning
Amount, when water flow becomes larger or gaseous-pressure becomes smaller, while the gas heating system adjusts heating, the electric heating system increases
Add power, for stablizing leaving water temperature；When water flow becomes smaller or gaseous-pressure becomes larger, the gas heating system adjusts heating
Meanwhile the electric heating system reduces power, for stablizing leaving water temperature.
Preferably, the central controller, which calculates the gas heating system, is adjusted to minimum controlled power, still can
When leaving water temperature being made to be higher than setting temperature, then the gas heating system stops heating, is mentioned completely by the electric heating system
For heated at constant temperature.
In conclusion the utility model has the following beneficial effects: can solve first gas heater set temperature and
The problem that leaving water temperature difference is larger, temperature stability is not high, secondly can it is small to avoid fast-type electric water heater water yield, to
The demanding pain spot of electric condition.
