Abstract
The invention provides an external optical wave heating type electric water heater provided with a water flow sensor with a pressure reduction function and a non-metallic blow-molded water tank. The water tank 8 is made of non-metallic materials through the blow molding technique, and the water flow sensor 4 with the pressure reduction function is installed on a water inlet pipeline of the water tank and is composed of a component A and a component B. According to the component A, when water flows in the component A, the water flow pushes an impeller or a rotor or a Hall element 4-8 to rotate, and a pulse signal or a current signal or a voltage signal or other signals are output by sensing the water flow rate, so that an intermediate relay is started, and a circuit is closed; and when the water is stopped, the circuit is opened. According to the component B, a transverse through hole is formed in the small end of a piston 4-9, and a through hole is further formed in the middle of the piston 4-9; when water enters the component B, the water passes through the transverse through hole and enters the water tank from the middle hole of the piston 4-9, and water enters the components B without being blocked when water intake is needed; and when the water tank is filled with water or the water intake amount is larger than water outlet amount, the pressure in the water tank is increased, backpressure is generated at the big end of the piston 4-9, the piston is made to move, and the opening degree of a water inlet 4-11 is decreased or even the water inlet 4-11 is closed. According to the heating way, a halogen or carbon fiber electric heating pipe is installed in air in a stainless steel sleeve for achieving heating.
