Abstract
The invention provides a non-metal injection-molded water tank electric water heater provided with a water flow sensor with a pressure reduction function. A water tank 8 is made of non-metal materials through an injection molding technique. The water flow sensor 4 with the pressure reduction function is installed on a water inlet pipeline of the water tank. The water flow sensor is composed of a component A and a component B. According to the component A, when water flows, an impeller or a rotor or a Hall element 4-8 is pushed by water flow to rotate, pulse signals or current signals or voltage signals and the like are output by sensing the water flow rate, an intermediate relay is pulled in, and thus a circuit is closed; and when the water supply is cut off, 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 inflows, water passes through the transverse through hole and then enters the water tank through the middle hole of the piston 4-9, and water is prevented from being blocked in the water inlet process; and when the water tank is filled with water or the water inlet amount is larger than the water outlet amount, the pressure in the water tank is increased, back pressure is generated by the big end of the piston 4-9, the piston is made to move, and accordingly the area of a water inlet 4-11 is decreased or even the water inlet 4-11 is closed.

Part A, when having water to flow, water jet propulsion impeller or rotor or Hall element 4-8 rotate, and by the sensing to discharge, the signal such as output pulse signal or electric current, voltage, makes auxiliary reclay adhesive, circuit turn-on, one or more groups electrothermal tube energising work；When closing water, water retention fluid stopping is moved, and circuit disconnects, and electrothermal tube stops heating；
Part B, piston 4-9 small end has a cross through hole, and also there is a through hole centre, during water inlet, water passes through transverse holes, enters in water tank from piston 4-9 interstitial hole, during water inlet, do not stop the entrance of water, when the built-in full water of water tank or inflow are more than water yield, when in water tank, pressure increases, the big end of piston 4-9 produces back pressure, make piston displacement, turn down and be even switched off water inlet 4-11；When discharging water, water inlet repeats to open；It is thus possible to the pressure in self-regulating water tank, this function guarantees that the pressure in water tank is within 0.15mpa.
The described water flow sensing unit with decompression, A and B can discrete be two stand-alone assemblies, and part A should be contained in inlet pipeline, and part B is arranged on inlet and outlet pipe.
Described water tank adopts nonmetallic materials injection moulding to make, and is tank body and shell be connected as a single entity, and for double-decker, or is separated with shell by tank body, and water tank is injection molded into single layer structure；Water tank is made up of the first product 8-1 and two nonsymmetrical component of the second product 8-2；First product and the second product open at one end, the other end is closed, and on the end face of unlimited one end, has some attachment screw installing holes, between and both ends of the surface binding site, installs sealing member 8-3, for double sealing structure；And on the inlet pipeline of water tank, it is provided with the water flow sensing unit of decompression；And in water tank, it is equipped with corresponding relief valve.
Beneficial effects of the present invention and novelty be:
Water inlet tube of electric water heater road, equipped with the water flow sensing unit 4 with decompression, within making the pressure in nonmetal injection moulding water tank reduce 0.07-0.15Mpa meanwhile, it is achieved with nonmetal making water tank, will not leak by crackle, without blast；
Accompanying drawing explanation
Fig. 1 to Fig. 3 is the water flow sensing unit structure chart with decompression；
Fig. 4 to Fig. 6 is equipped with the electric heater schematic diagram of the water flow sensing unit with decompression；
Detailed description of the invention
Below in conjunction with accompanying drawing 1 to embodiment illustrate, in accompanying drawing: shell 1, cold water inlet 2, hot water outlet pipe 3, with the water flow sensing unit 4 of decompression, controller 5, electrothermal tube 6 (upper electrothermal tube 6-1, lower electrothermal tube 6-2), seal and fixing point 7, water tank 8, water nozzle 9, thermometric or limit temperature sensor install pipe 10, flange 11, relief valve 14.
Fig. 1 to Fig. 3 is the water flow sensing unit 4 with decompression, by main body 4-1, cover plate 4-2, sealing member 4-3, spring 4-4, cover plate 4-5 is installed, sensing element 4-6, binding post 4-7, impeller or rotor or Hall element 4-8, piston 4-9, interface 4-10, water inlet 4-11 are constituted.The described water flow sensing unit with decompression, is made up of two Functional portions A and B:
