Described 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 the water flow switch 4 installed on water tank water intake pipeline with decompression; And at the outlet pipeline of water tank 8, external fast heating device 16 is housed, simultaneously in water tank just containing arranging relief valve.
Described external fast heating device is the out-of-date i.e. water-heating devices 16 of current, be in a small container, electrothermal tube be set, and have water inlet and delivery port, intake from water tank 8 top, open water nozzle 9, when having water flow, electrothermal tube 6 is energized work, water flows through electrothermal tube and is namely heated, release hot water by delivery port, close water nozzle, stop heating.
Beneficial effect of the present invention and novelty are:
1. water inlet tube of electric water heater road, is equipped with the water flow switch 4 of band decompression, within making the rated pressure in nonmetal blowing water tank reduce 0.07-0.15Mpa, realizes making water tank with nonmetallic materials blow molding process, can not leak by crackle meanwhile, also can not explode.
2. the water inlet of water tank and outlet pipe all adopt the flexible nonmetallic tubing of length > 500mm and nonmetal tank body jointly to form physics water resistance, are perfectly safe.
Accompanying drawing explanation
Fig. 1, Fig. 2, Fig. 4, Fig. 5 are the Water flow switch structure figure of band decompression;
Fig. 3 is microswitch schematic diagram;
Fig. 6 to Figure 10 is the external quick-heating type electric water heater schematic diagram of nonmetal blowing water tank of the water flow switch that band decompression is housed;
Detailed description of the invention
Embodiment below in conjunction with accompanying drawing 1 to 10 is described, in accompanying drawing: shell 1, cold water inlet 2, hot water outlet pipe 3, water flow switch 4 with decompression, controller 5, electrothermal tube 6 (upper electrothermal tube 6-1, lower electrothermal tube 6-2), sealing and fixing point 7, water tank 8, water nozzle 9, thermometric or temperature limit switch mounting pipe 10, flange 11, relief valve 14, sewage draining exit 15, water flow through water-heating device 16, metal or non-metallic casing 17, air 18, water 19.
Fig. 1, Fig. 3 to Fig. 5 are the water flow switches 4 with decompression, are made up of A, B bis-functional parts.
Part A, in main body 4-1, the passage of water inlet and water outlet is not directly communicate, but separated by cover plate 4-2, when there being water flow, water can be forced promotion cover plate 4-2, simultaneously promotion seal 4-3 with impeller 4-4 and movable contact 4-9 contacted with stationary contact 4-8 or microswitch 4-7 is connected, circuit turn-on: when current are closed, water inlet is closed, and circuit also disconnects.(in accompanying drawing, spring or spring leaf 4-5, cover plate 4-6, binding post 4-10)
Part B, piston 4-12 small end has a cross through hole, and centre is also porose, during water inlet, water, by transverse holes, enters in water tank from piston 4-12 interstitial hole, during water inlet, not the entering, when the in-built full water of water tank or inflow are greater than water yield, in water tank during pressure increase of block water, piston 4-12, large end produces back pressure, and piston 4-12 is subjected to displacement, and turns down and even closes water inlet 4-14; 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.
Fig. 6 to Figure 10 is the electric heater structural representation of the water flow switch 4 that band decompression is housed; Water tank water intake is by with the water flow switch 4 of decompression, and no matter pipe-line system pressure size, can make water tank fill water fast, and make it be limited in setting range; At the outlet pipeline of water tank 8, external fast heating device 16 is housed.
In accompanying drawing, water tank adopts nonmetal blowing manufacture, and as Fig. 6 to Figure 10, pressure is limited in 0.1 to 0.2Mpa, and this just thoroughly overcomes water tank makes water tank crackle leak water problem because expanding with heat and contract with cold.
In accompanying drawing, electric heater has horizontal type structure, also has vertical 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, jointly form physics water resistance, guarantee to be perfectly safe with tank body.
Described electrothermal tube 6 is in metal tube, and dress heating wire, with magnesia powder, by heating wire and tube wall isolated insulation, is equipped with binding post at heating wire two ends.
If by A and B of the water flow switch of band decompression, be divided into two assemblies, be contained in water tank, also within this patent protection.
