Electricity.
Power supply of the temperature controller control to electric heating tube, when temperature is less than set temperature, power-supply controller of electric are equipped with by water tank
Circuit to electric heating tube is connected, and when temperature is greater than or equal to set temperature, the circuit of power-supply controller of electric to electric heating tube is disconnected
It opens, temperature controller is powered to it by external 220V alternating currents, when temperature controller powers off, the circuit of power-supply controller of electric to electric heating tube
It is off.
The utility model has the beneficial effects that：
1, use output voltage in the photovoltaic panel feed-tank of 190V-240V electric heating tube power supply, be not only lost it is low, and
And a heating tube can be shared with the alternating current of 220V, it is simple in structure, at low cost.
2, when summer and fine day, power-supply controller of electric can be pushed to the 190V-240V direct currents exported with photovoltaic panel to electricity
Heating tube is powered one end；When winter and cloudy day or rainy day, the electric energy of the output of solar energy photovoltaic panel is inadequate, and water temperature, which is not achieved, to be set
When constant temperature is spent, power-supply controller of electric can be pushed and be powered one end to electric heating tube with external 220V alternating currents；And two kinds of power supplys are all
The power supply to electric heating tube is controlled by temperature controller, water temperature will not be excessively high, and electric heating tube is not likely to produce incrustation scale, and the thermal efficiency is high, makes
With long lifespan, good reliability.
3, the 190V-240V direct currents exported using photovoltaic panel are powered directly to the electric heating tube of water heater, thermal efficiency height,
It is lost less, is simple in structure；It is powered to temperature controller using external 220V alternating currents, voltage stabilization, good reliability.
As it can be seen that a kind of solar photovoltaic water heater of the utility model is simple in structure, at low cost, good reliability, no matter winter
It can be all convenient to use with summer.
