Three, 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, sealing member 8-3 is installed, for double sealing structure.
Several different water tanks above, at the outlet pipeline of water tank 8 equipped with fast heating device 16, are intended to be equipped with corresponding relief valve in water tank.
The described water flow sensing unit 4 with decompression, is made up of bis-functional parts of A, B:
Part A, when having water to flow, water jet propulsion impeller or rotor or Hall element 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 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 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 9 produces back pressure, make piston displacement, turn down and be even switched off water inlet 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.
The out-of-date i.e. water-heating device 16 of described current, is in a small container, arranges electrothermal tube, and have water inlet and outlet, being intake from water tank 8 top, open water nozzle 9, electrothermal tube 6 is energized work, and water flows through electrothermal tube and is namely heated, release hot water by outlet, close water nozzle, stop heating.
Beneficial effects of the present invention and novelty be:
1. electric heater is built with the water flow sensing unit 4 with decompression, makes the pressure in water tank be reduced within 0.07-0.15Mpa by 0.6Mpa, can reduce water tank thickness, save material, will not leak by crackle meanwhile；Without blast；
2. particularly, the Stress control of nonmetal water tank, within 0.03 to 0.1Mpa, thus water tank 8 can make by nonmetallic materials blowing or Shooting Technique, thoroughly changes the manufacturing process of Water tank for electrical water heater, is a great innovation of electric heater over 140 years.
3. this electric heater can also realize fast heat, is front unexistent.
Accompanying drawing explanation
Fig. 1 to Fig. 3 is the structure chart of the water flow sensing unit with decompression；
Fig. 4 to Figure 10 is equipped with the external quick-heating type electric water 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, water flow sensing unit 4 with decompression, controller 5, electrothermal tube 6 (upper electrothermal tube 6-1, lower electrothermal tube 6-2), outlet pipe fixed pivot 7, water tank 8, water nozzle 9, thermometric or temperature limit switch install pipe 10, flange 11, relief valve 14, sewage draining exit 15, the out-of-date water-heating device 16 of current.
Fig. 1 to Fig. 3 is the water flow sensing unit structure chart with decompression, and structure is similar, and function is close, and simply connected mode is different.
