Technical field
The present invention relates to the nonmetal blowing water-tank electric water heater of optical wave heating of the water flow sensing unit that band decompression is housed.
Background technology
Domestic, electric water heater all in the world at present, inlet pipeline is connected with water source, from water inlet to water tank, other assemblies are not installed, all can not pressure in self-regulating water tank, be all adopt pressure-bearing type structure, rated pressure is generally 0.6Mpa, and test pressure is 1.2Mpa; This pressure there will be many insoluble problems; The water tank that such as expands with heat and contract with cold can crackle, leak, pressure conference blast, be world-famous puzzle.
Summary of the invention
The present invention improves existing electric heater, for being equipped with the nonmetal blowing water-tank electric water heater of optical wave heating of the water flow sensing unit of band decompression after improvement, be made up of shell 1, water inlet pipe 2, outlet pipe 3, the water flow sensing unit 4 with decompression, optical wave heating electrothermal tube 6, water tank 8, water nozzle 9, flange 11, relief valve 14.
The described water flow sensing unit 4 with decompression, by main body 4-1, cover plate 4-2, seal 4-3, spring 4-4, cover plate 4-5, sensing element 4-6, binding post 4-7, impeller or rotor or Hall element 4-8, piston 4-9 are installed, interface 4-10, water inlet 4-11 form.The described water flow sensing unit with decompression, is made up of two Functional portions A and B:
Part A, when having water flow, water jet propulsion impeller or rotor or Hall element 4-8 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 4-9 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 4-9 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 4-9 produces back pressure, make piston displacement, turn down and even close water inlet 4-11; 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.
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 sensing unit 4 installed on the inlet pipeline of water tank with decompression; The mode of heating simultaneously adopted in water tank 8, is the halogen of light wave heating or carbon fiber electric heating tube are contained in the air in stainless steel sleeve pipe, realizes water proof heating; And in water tank, be equipped with corresponding relief valve.
Described optical wave heating, is nonmetallic halogen or carbon fiber electric heating tube are contained in the air 18 in metal or non-metallic casing 17, and metal or non-metallic casing is firmly connected with water tank 8, guarantee that electrothermal tube and water separate completely; The simultaneously heating wire of electrothermal tube 6 and nonmetal tube wall spacing > 2mm; Electrothermal tube 6 and sleeve pipe 17 spacing > 0.5mm, reach the requirement of reinforced insulation, realize water heater and connect without ground wire, become two electric appliances.
Beneficial effect of the present invention and novelty are:
1. water inlet tube of electric water heater road, is equipped with the water flow sensing unit 4 of band decompression, within making the pressure in nonmetal blowing water tank reduce 0.05-0.15Mpa, can reduce water tank thickness, save material, can not leak by crackle meanwhile, also can not explode;
2. this electric heater, the halogen generate heat light wave or carbon fiber electric heating tube are contained in the air in metal or non-metallic casing, realize water proof heating, are perfectly safe.

Detailed description of the invention
Embodiment below in conjunction with accompanying drawing 1 to 8 is described, in accompanying drawing: the halide torch of shell 1, cold water inlet 2, hot water outlet pipe 3, water flow sensing unit 4 with decompression, controller 5, optical wave heating or carbon fiber pipe 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 limit temperature sensor 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 to Fig. 3 is the water flow sensing unit 4 with decompression, by main body 4-1, cover plate 4-2, seal 4-3, spring 4-4, cover plate 4-5, sensing element 4-6, binding post 4-7, impeller or rotor or Hall element 4-8, piston 4-9 are installed, interface 4-10, water inlet 4-11 form.The described water flow sensing unit with decompression, is made up of two Functional portions A and B, is multifunctional module:
Part A, when having water flow, water jet propulsion impeller or rotor or Hall element 4-8 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 4-9 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 4-9 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 4-9 produces back pressure, make piston displacement, turn down and even close water inlet 4-11; 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.
Fig. 4 to Fig. 8 is the optical wave heating nonmetal blowing water-tank electric water heater structural representation of the water flow sensing unit 4 that band decompression is housed; Water tank water intake is by with the water flow sensing unit 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.
In accompanying drawing, water tank adopts nonmetallic materials blowing manufacture, is limited to by pressure in 0.15Mpa, and this just thoroughly overcomes and 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, form physics water resistance, guarantee safety.
Described optical wave heating electrothermal tube 6, is nonmetallic halogen or carbon fiber electric heating tube are contained in the air of metal or non-metallic casing (17), and metal or non-metallic casing is firmly connected with water tank, guarantee that optical wave heating electrothermal tube and water separate completely.
If by band decompression water flow sensing unit 4 A and B firmly row be divided into two assemblies, be arranged in water tank, also this patent protection within; Arrow is water (flow) direction.
