Photovoltaic heating PTC electric water heater

Abstract

The invention belongs to the technical field of water heaters, and relates to a photovoltaic heating PTC electric water heater. The photovoltaic heating PTC electric water heater comprises a water heater shell, an inner container, PTC heating bars and a power source. The PTC heating bars are inserted in an inner container cavity. The photovoltaic heating PTC electric water heater is characterized in that a heater is arranged and comprises a shell, an air blower and a PTC heater, the shell is provided with an air inlet and an air outlet, and the air blower is arranged at the air inlet; the power source is a photovoltaic power source and comprises a photovoltaic generating plate, a photovoltaic controller and a photovoltaic storage battery; and the photovoltaic storage battery is connected with the PTC heating bars inserted in the inner container, the air blower arranged in the shell of the heater and the PTC heater. The photovoltaic heating PTC electric water heater is simple and reasonable in structure, power generating and heating are carried out through solar energy, and energy saving and environment protection are achieved; and meanwhile the heater is arranged, and when people take a bath in winter, the heater can be started, and cold catching due to bath taking is avoided. The photovoltaic heating PTC electric water heater has the beneficial effects of saving energy, protecting the environment, providing warm air, purifying air, performing sterilizing and the like, and wide market space is achieved.

Description

technical field [0001] The invention relates to a structure of an electric water heater, in particular to a structure of a photovoltaic heating PTC electric water heater, belonging to the technical field of water heaters. Background technique [0002] PTC generally refers to semiconductor materials or components with a large positive temperature coefficient. Usually, the PTC we refer to refers to a positive temperature coefficient thermistor, referred to as a PTC thermistor. PTC has extremely low impedance and small size at room temperature, and can be widely used in overcurrent protection of various circuits and electrical appliances, and can be installed separately to maximize the safe use of each line, making up for the shortcomings of the previous centralized protection circuit. [0003] PTC responds quickly to overload current, stable and reliable performance; strong impact resistance, long service life; non-polarity, AC and DC are available; small size, can process and...

AI Technical Summary

Problems solved by technology

[0004] Today's energy issues have always attracted people's attention. The existing PTC electric water heaters are generally powered by mains electricity, which does not meet the trend of energy conservation and environmental protection.

And the existing electric water heater does not have a heating device when taking a bath, and it is easy to catch cold when the weather is cold, which cannot meet people's needs
