Description

A kind of improved inner container of electric water heater

Technical field

The utility model belongs to technical field of water heaters, particularly a kind of follow-on inner container of electric water heater.

Prior art

At present, kind and the style of selling the electric heater that uses on the market are more and more, and function also is not quite similar.And existing inner container of electric water heater generally can be divided three classes according to the material difference: the one, on the plain steel inwall, add the coat of metal and plastic lining resin bed; The 2nd, form with nickel chromium stainless steel weldering system; The 3rd, make enamel inner container at plain steel or stainless steel base coated inner wall enamel material.Because the existence of chlorion in the water, preceding two kinds of inner bags corrode under the effect of high temperature chloride ion-containing water for a long time easily, therefore, existing inner container of electric water heater requires to possess the high temperature resistant and water-fast corrosion of energy, and enamel inner container is promoted the use of widely because of having advantages such as excellent corrosion resistance and long service life.

In the prior art, enamel inner container electric heater, its inner bag be a columnar container normally, change amount of capacity by the diameter that changes inner bag, when the need larger capacity, the inner bag diameter just need be accomplished very big, like this, be placed in the bathroom and will occupy very big space.

In order to dwindle the enamel inner container diameter, reach the purpose of dwindling electric heater volume and thickness, enamel inner container is general to adopt two inner-tube structures to design, with two circle with a smaller diameter tubular inner bags serial connections.Nowadays, generally one of serial connection mode of Shi Yonging is to adopt some tube connectors in the middle of two roundlet tubular inner bags, fixing by being welded to connect, this structure welding procedure complexity, the production process operability is not good, and in the enamel process because the out-of-flatness of tube connector place, cause the enamel layer at tube connector position inhomogeneous easily, lack defective such as porcelain, cause consequences such as carbon steel inner bag corrosion; The serial connection mode another for to weld some flange flanges respectively at two inner bag centre circles, two inner bags dock flange behind the enamel separately again, fixing in the welding of the flange outside, this structure welding procedure is complicated equally, weld seam is many, and welding again behind the enamel, destroy the enamel layer of junction easily, cause inner bag to have no porcelain district, stay the hidden danger of quality of inner bag corrosion.

The utility model content

In order to overcome above-mentioned the deficiencies in the prior art, the utility model discloses a kind of improved inner container of electric water heater structure, this inner-tube structure adopts two inner bag combinations, capacity is big, hot and cold water mixes, goes out hot water rate height, in addition its can layout welding procedure rationally order, have advantages such as the weld seam of minimizing, technology are simple.

For achieving the above object, the utility model is realized by following technical scheme:

A kind of improved inner container of electric water heater described in the utility model, comprise serial connection and first inner bag and second inner bag that are communicated with, the described first inner bag both ends are provided with end cap and flange end cap respectively, the end of second inner bag also correspondence is provided with end cap and flange end cap, described first inner bag and the second inner bag inner wall surface all are coated with enamel layer, described first inner bag and the equal corresponding some connectors that are provided with in the junction of second inner bag, the connector place of described first inner bag is provided with the outer flanging of outside turnover, the connector place of described second inner bag is provided with the interior flanging of inside turnover, the outer flanging of described first inner bag is serially connected first inner bag and second inner bag with the corresponding welding of the interior flanging of second inner bag is fixing, the described second inner bag sidewall is provided with some through holes with respect to the position of connector, on described each through hole all by weld tabs be connected water pipe and connect.

Further improvement as above-mentioned technology, the through-hole diameter size of correspondence is greater than the size of first inner bag and the second inner bag connector place diameter, so just comparatively easily by the flanging corresponding welding of through hole to each connector of first inner bag and second inner bag on described second inner bag.

In the utility model, described first inner bag and second inner bag are up and down arranges side by side.

As the further improvement of above-mentioned technology, the number of connector is three on described first inner bag and second inner bag, all evenly arranges along the sidewall of inner bag, corresponding with it, the number of through-holes on the second inner bag sidewall also is three.Certainly, the number of connector and through hole also can be offered according to concrete actual needs, for example: for jumbo inner bag, can be four, five or six etc.

Compared with prior art, the beneficial effects of the utility model are:

(1) in the utility model, the weld seam at each connector place of each inner bag has only one, and than the weld seam of other structure decrease 2/3, production technology is simplified, and reliability improves;

(2) the utility model is compared than prior art, owing to cancelled tube connector, the cost of manufacture of having saved inner bag greatly;

(3) mixing of the hot and cold water between each inner bag is more even in the utility model, in addition, because each courage is independently, can realize the raising of hot water delivery rate again, fully effectively utilizes hot water;

(4) the utility model inner bag has welding procedure in unique courage, welding earlier, and back enamel makes inside 100% enamel coating of inner bag cover, and eliminates inner bag and makes the hidden danger of quality that inner bag easily is corroded because of the no porcelain of existence district.
