Abstract
The invention provides an external rapid-heating type electric water heater provided with a water flow sensor with a pressure reduction function and a metallic water tank. The water tank 8 is made of metallic materials, 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 functional component A and a functional component B. According to the functional component A, when water flows in the functional 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, a circuit is closed, and one or more set of electric heating pipes are powered on to work; and when water is stopped, the water stops flowing, the circuit is opened, and the electric heating pipes stop heating. According to the functional 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 functional 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 functional components B without being blocked when water intake is needed; 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; and when the water is drained, the water inlet is opened repeatedly. In this way, the pressure in the water tank can be regulated automatically. Meanwhile, an external rapid heating device 16 is installed on a water outlet pipeline of the water tank 8.
