Two, water tank adopts nonmetallic materials blowing to make, namely multilayer blow moulding manufacture technics inner bag is adopted, be made up of one deck or more different materials when described multilayer blow moulding refers to wall of inner container blowing, be send into the different raw material of several performance, disposal molding with multiple hopper simultaneously; And on water tank water intake pipeline the water flow sensing unit 4 of mounting strap decompression; The out-of-date i.e. water-heating device 16 of current is housed simultaneously in the outlet pipeline of water tank 8.
Three, water tank adopts nonmetallic materials injection moulding to make, and be tank body and shell are connected as a single entity, be double-decker, or be separated with shell by tank body, water tank is injection molded into single layer structure; Water tank is made up of the first product 8-1 and the second product 8-2 two nonsymmetrical component; 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, and between, both ends of the surface binding site, installing seal 8-3, is double sealing structure.
Several different water tank, is equipped with fast heating device 16 at the outlet pipeline of water tank 8 above, all will be equipped with corresponding relief valve in water tank.
The described water flow sensing unit 4 with decompression, is made up of A, B bis-functional parts:
Part A, when having water flow, water jet propulsion impeller or rotor or Hall element 8 rotate, and by the induction to discharge, output pulse signal or the signal such as electric current, voltage, make auxiliary reclay adhesive, circuit turn-on, one or more groups electrothermal tube energising work; When closing water, water stops flowing, 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, by transverse holes, enters in water tank, during water inlet from piston 9 interstitial hole, not the entering of block water, when the in-built full water of water tank or inflow are greater than water yield, in water tank during pressure increase, the large end of piston 9 produces back pressure, make piston displacement, turn down and even close water inlet 11; When discharging water, water inlet repeats to open; Thus can pressure in self-regulating water tank, this function guarantees that pressure in water tank is within 0.15mpa.
The described water flow sensing unit with decompression, A and B can discretely 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 delivery port, be from the water inlet of water tank 8 top, fetch boiling water and chew 9, electrothermal tube 6 is energized work, and water flows through electrothermal tube and namely heated, release hot water by delivery port, close water and chew, stop heating.
Beneficial effect of the present invention and novelty are:
1. electric heater is built with the water flow sensing unit 4 of band decompression, within making the pressure in water tank be reduced in 0.07-0.15Mpa by 0.6Mpa, can reduce water tank thickness, saves material, can not leak by crackle meanwhile; Also can not explode;
2. particularly, the Stress control of nonmetal water tank is within 0.03 to 0.1Mpa, thus water tank 8 can make by nonmetallic materials blowing or Shooting Technique, and thoroughly changing 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 the external quick-heating type electric water heater schematic diagram of water flow sensing unit that band decompression is housed;
Detailed description of the invention
Embodiment below in conjunction with accompanying drawing 1 to Figure 10 is described, in accompanying drawing: shell 1, cold water inlet 2, hot water outlet pipe 3, the band water flow sensing unit 4 of 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 chew 9, thermometric or temperature limit switch mounting 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, similar, and function is close, and just connected mode is different.
Fig. 4 to Figure 10 is the external quick-heating type electric water heater structural representation of the water flow sensing unit 4 that band decompression is housed; Water tank water intake, by the water flow sensing unit 4 of band decompression, no matter pipe-line system pressure size, can make water tank fill water fast, and make it be limited in setting range.
Meanwhile, nonstorage calorifier 16 is installed in water tank, described Fast Heating refer to summer and spring and autumn sky, can hot-water supply be stablized within 20 seconds; Winter just need be preheated to about 50 DEG C:
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 delivery port, fetch boiling water and chew 9, and electrothermal tube 6 is energized work, and water flows through electrothermal tube and namely heated, and releases hot water by delivery port, closes water and chews, stop heating;
In accompanying drawing, water tank can make of nonmetal blowing or injection moulding, if nonmetal water tank, pressure is limited to about 0.1Mpa, because nonmetal water tank has dilatancy hot, heat expansion pressure can be absorbed, and back pressure is produced to piston, and the Shi Zehui that discharges water allows the pressure of pipe-line system pass through, its water yield is identical with existing water heater; Water tank also can adopt metal to be base material liner enamel or manufacture with stainless steel, if metal water tank (containing enamel and stainless steel water tank), pressure is limited in 0.2Mpa, and this just thoroughly overcomes water tank makes water tank enamel split because expanding with heat and contract with cold, the problem of bead crack.
In accompanying drawing, electric heater has vertical structure, also has horizontal type structure, can be general, is that single water tank or many water tanks are all general.
In accompanying drawing, the water inlet pipe of water tank and outlet pipe are all the flexible nonmetallic tubings adopting length > 500mm, form physics water resistance, guarantee safety.
Described electrothermal tube 6, can adopt nonmetallic halogen electrothermal tube or the carbon fiber electric heating tube of metal stainless steel electrothermal tube or optical wave heating.
If by A and B of the water flow sensing unit 4 with decompression, hard row analysis is that two assemblies are also within the protection of this patent; Arrow is water (flow) direction.
