Description

There are external semiconductor or the luminous energy heating injection moulding water-tank electric water heater of water flow switch

Technical field

The present invention relates to external semiconductor or the luminous energy heating injection moulding water-tank electric water heater of water flow switch.

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, water tank is 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 the electric heater that existing metal material makes water tank, for having external semiconductor or the luminous energy heating injection moulding water-tank electric water heater of water flow switch after improvement, be made up of shell 1, water inlet pipe 2, outlet pipe 3, the water flow switch 4 with decompression, electrothermal tube 6, water tank 8, water nozzle 9, flange 11, relief valve 14, external fast heating device 16;

Described water flow switch 4, is made up of A, B bis-parts:

Part A, in main body 4-1, the passage of water inlet and water outlet is 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.

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.

Described electrothermal tube 6, is semi-conductor electricity heat pipe, is by semiconductor heating material, is coated in quartz glass tube inner wall surface, forms one deck conducting film, and has binding post, can produce infra-red radiation and heat energy after energising; This electrothermal tube, also referred to as semiconductor heating pipe, its conducting film is a kind of polysilicon semiconductor silicate material, and made quartz glass semi-conductor electricity heat pipe is contained within water tank 8, Electric radiant Heating Film and water completely isolated; Two is luminous energy electrothermal tubes is at the in-built carbon fiber of quartz glass tube or metal heating wire, produces infra-red radiation and heat energy after energising.

Described 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 and both ends of the surface binding site, respectively installing seal 8-3, is double sealing structure; And the water flow switch 4 installed on water tank water intake pipeline with decompression, at the outlet pipeline of water tank 8, fast heating device 16 is housed, in water tank, is equipped with corresponding relief valve.

The out-of-date i.e. water-heating device 16 of current of described external fast heat, 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 injection moulding water tank reduce 0.07-0.15Mpa, realizes making water tank by nonmetallic materials Shooting Technique, can not leak by crackle meanwhile; Also can not explode.

2. this electric heater, adopts semiconductor or luminous energy to realize water proof heating, is perfectly safe.
