Abstract

The utility model relates to an integrated electric water heater which is composed of a component 1, a water tank liner cover 5, a left cover 6 and a right cover 7 (or an upper cover 8 and a lower cover 9) and an electric heating tube 4, wherein the component 1 is integrally formed by a water tank liner and an outer shell; a sealing element 11 is arranged between the water tank liner 1-1 and the water tank liner cover 5; a plurality of bolts 12 are used for tightly clamping the water tank liner, the water tank liner cover and the sealing element, so as to prevent water leakage; a plurality of connecting reinforcing ribs 20 are arranged between the water tank liner 1-1 and the outer shell 1-2 and are used for reinforcement; a technical method for injection molding is adopted for the component 1 which is integrally formed by the water tank liner and the outer shell; the technical method comprises the following stages: assembling the mould, injecting a heated molten thermoplastic plastics material into a mould cavity under high pressure, keeping the pressure, cooling and solidifying, and then opening the mould, thereby manufacturing the end product.

Description

Integrated electric hydrophone

Technical field

The present invention relates to storage-type electric water heater, relate generally to the integrated storage-type electric water heater of inner water tank and shell.

Background technology

Existing storage-type electric water heater mainly comprises the parts such as inner water tank and shell, the inner bag that its electric heater is used, all to make by the version of standard QB/T4101-2010 < < electric water heater with water tank inner bag > >, be glass lining metal inner tube, take steel as base material, enamel material is as the inner bag of anti-rotten protective finish; Also have plastic inner lining metal inner tube, take steel as base material, the inner bag that plastics or similar material are anti-rotten protective finish: meanwhile, after inner bag is carried out, outside also will wrap up with shell.

This storage-type electric water heater manufacturing process is complicated, first by metal plate punching moulding and welding, test pressure, then at inner enamel coating or be coated with plastics, with shell parcel and foam, form heat-insulation layer again between shell and inner water tank: in manufacture process, need the workman that is skilled in technique in a large number; Meanwhile, due to iterative cycles under the condition of work of expanding with heat and contract with cold, weld seam meeting crackle, causes and leaks, and is the world-famous puzzle over more than 130 year.

Summary of the invention

The structure and the manufacture method that the present invention is directed to existing storage-type electric water heater are improved:

1, improve structure: the assembly 1 that integrated electric hydrophone is shaped by inner water tank and shell integral type and inner water tank lid 5, left cover 6 and right cover 7 (or upper cover 8 and lower cover 9) and electrothermal tube 4 form; Between inner water tank 1-1 and inner water tank lid 5, there is seal 11, with a plurality of screws 12, by inner water tank and inner water tank lid and seal clamping, prevent from leaking.

2, improve manufacturing process: the assembly 1 that inner water tank and shell are connected as a single entity, take the process of injection mo(u)lding, be divided into the next stage: matched moulds---by the thermoplastic material that is heated and melts, with high pressure, inject die cavity,---pressurize---after cooling curing---die sinking, produces finished product.

Described inner water tank and shell integral molding, refer to and use same mould, only time processing technique, to be divided in the past inner water tank and shell, the original part by one-step of manufacturing separately completes, and between inner water tank and shell, with some connection strengthening ribs 20, strengthen.

The described assembly 1 being shaped by inner water tank and shell integral type, on the storage-type electric water heater of making, should be equipped with 2 above relief valves 13; On the control circuit of electrothermal tube 4, temperature limit switch should be housed or claim temperature switch or kick switch more than 2, within can being arranged on thermometric or temperature limit switch mounting pipe 10, also can be arranged on inner water tank lid 5.

Advantage of the present invention is with plastics instead of steel, and inner water tank and shell are made as to one, can Optimization Technology and reduction manufacturing cost.

The specific embodiment

Below in conjunction with accompanying drawing, describe, the assembly 1 that in accompanying drawing, inner water tank and shell are one of the forming is (during statement, available inner water tank 1-1, shell 1-2), plastics water inlet pipe 2, plastic water outlet pipe 3, electrothermal tube 4 (halide torch or carbon fiber pipe 4-1, metal electric heat pipe 4-2, alumina ceramic heating pipe 4-3), inner water tank lid 5, left cover 6, right cover 7, upper cover 8, lower cover 9, thermometric or temperature limit switch mounting pipe 10, seal 11, screw 12, relief valve 13, metal or non-metallic pipe 14, water 15, friction top 17, water chews 18, hot water collecting hood 19, connection strengthening rib 20 between inner water tank and shell,

The assembly 1 being connected as a single entity with inner water tank and the shell of injection moulding, while making storage-type electric water heater, multiple electrothermal tube 4 be can select, the halide torch and the carbon fiber pipe 4-1 that produce light and heat after energising work in Fig. 1, selected, be mounted in the air 16 of metal tube 14, realize water proof heating; Metal tube 14 one end are fixed on the assembly 1 that inner water tank and shell be integrally formed, and the other end is bearing on inner water tank lid 5; Hot water collecting hood 19 also can be installed in outside at metal tube 14, and hot water is delivered to top fast, described hot water collecting hood is a semicircular hood shell, upwards has many pipes, heated water can upwards send fast, and unnecessary hot water can carry out heat exchange by two ends and bottom and water at low temperature around; If electrothermal tube is available 4-2 or 4-3 also, be arranged on inner water tank lid 5, now, if without metal or non-metallic pipe 14, only with hot water collecting hood, if with metal or non-metallic pipe 14, Guan Shangying has water inlet and delivery port.

Fig. 2 be Fig. 1 remove cover 7 and the right side of inner water tank lid 5 to view, diagram cylindrical be circle, depending on different product, cross sectional shape can be selected arbitrarily.

Fig. 3 has installed metal or non-metallic pipe 14 on inner water tank lid 5, and electrothermal tube 4-1 or 4-3 are installed within it; On the assembly 1 being connected as a single entity at inner water tank and shell, 2 relief valves 13 should be installed, controlling on every circuit of electrothermal tube 4, temperature limit switch (or claiming temperature switch or kick switch) should be installed more than 2, within can being arranged on thermometric or temperature limit switch mounting pipe 10, also can be arranged on inner water tank lid 5.

Inner water tank in accompanying drawing, has single barrel, twin-tub or many barrels, and shape in bucket, can be circle or abnormity, and the form of setting has horizontal and vertical; In cavity between inner water tank 1-1 and shell 1-2, can insert heat-insulating heat-preserving material; Arrow is water (flow) direction.
