Wind-energy water heater with circuit switching device

Abstract

The invention discloses a wind-energy water heater with a circuit switching device. The wind-energy water heater comprises a wind driven generator driven by fan blades, a rectifying device, a power storage device and an electric heating element arranged in a water tank, wherein the wind driven generator, the rectifying device, the power storage device and the electric heating element are electrically connected in sequence. The rectifying device is connected to the input end of the power storage device, and the electric heating element is connected to the output end of the power storage device. The wind-energy water heater is characterized in that the circuit switching device is electrically connected to the rectifying device and is also electrically connected with the mains supply and the input end of the power storage device. The wind-energy water heater with the circuit switching device can stably supply power, a large amount of electric energy of the mains supply can be saved, and wind energy is fully utilized.

Description

technical field [0001] The invention relates to the field of wind energy water heaters, in particular to a wind energy water heater capable of switching a power supply circuit according to the state of wind energy. Background technique [0002] Wind energy water heaters are environmentally friendly heating equipment widely used in islands and high-rise buildings. The principle of traditional wind energy water heaters is to use the wind to drive the fan blades to rotate, and drive the generator to generate electricity, and then charge the generated electricity to the battery. And the output end of storage battery is then connected on the heating piece in the water tank, heats the water in the water tank with this. However, due to the extremely poor stability of wind energy, the electricity generated by wind power is insufficient, resulting in an unsteady level of electricity in the battery and extremely unstable workload of the heating element. Therefore, traditional wind ene...

Problems solved by technology

However, the above structure has two major defects

First, the stability of wind power generation is poor. If the wind power generation lead is directly connected to the water heater, the water heater cannot operate at the rated power, which will not only affect the use of the water heater, but also damage the service life of the water heater; When the water heater is connected to the wind power at the same time, since the city power continues to supply power at a stable power, and the wind power only plays an auxiliary role in the entire power supply process, the water heater will greatly reduce the use effect of the electric energy generated by the wind power. The utilization rate is extremely low and a large amount of mains power will be wasted
