Portion.
Preferably, the upward bending in the outer ring edge in the annular stop portion forms coaming plate, the coaming plate and the shell
Bottom end opening is fixedly connected.
Preferably, the coaming plate is enclosed in the outside of the shell bottom end opening.
Preferably, the outer wall of the shell bottom end opening be equipped with one circle location indentations, the coaming plate inner wall fitting described in
The outer wall of location indentations.
Preferably, the coaming plate is fixedly connected with the opening of the shell bottom end by screw.
Preferably, the coaming plate is fixedly connected with the opening of the shell bottom end by welding manner.
Preferably, the lower head is fixed with cylinder in the liner by welding manner.
The present invention also protects a kind of water tank, which includes above-mentioned water tank lower head structure
Preferably, sealing is fixed on the upper cover on cylinder top in the liner.
Preferably, the top of the shell is equipped with opening, and the housing top end opening is closed by upper capping.
Preferably, the bottom end outer wall of the upper capping is equipped with a circle attachment recess, the inner wall patch of the housing top end opening
Close the outer wall of the attachment recess.
Preferably, spacing is equipped between the upper cover and the upper capping.
Preferably, cylinder, upper cover and lower head group are combined into liner component, the shell and upper cover combination in the liner
For casing assembly, foamed material is filled between this casing assembly of institute and liner component.
The present invention also protects a kind of water heater, which includes above-mentioned water tank.
Compared with prior art, the present invention at least has the advantages that
Water tank lower head structure proposed by the present invention has set the annular stop portion of closure bottom opening on lower head, can
To prevent foamed material from overflowing in the bottom for entering lower head, the stability of equipment is improved；But also there is positioning action, it is therefore prevented that
Relative motion occurs in foaming process for liner and shell.
Detailed description of the invention
Fig. 1 is the structure chart of an embodiment；
Fig. 2 is the liner assembly assumption diagram of an embodiment.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Scheme shown in -2 referring to Fig.1, for a kind of water tank lower head structure that one embodiment of the present of invention provides, it is wrapped
Shell 1 is included, is equipped with cylinder 2 in liner inside shell 1, the bottom end of shell 1 has set opening, and the bottom end fixation of cylinder 2 is set in liner
There is lower head 3, which is equipped with annular stop portion, and annular stop portion is used for the opening of the bottom end of closure 1, so
There is no need to also set a lower plate in the lower section of lower head as original structure, foamed material would not be from lower plate for design
Gap between lower head enters in the recess space of lower head, and foamed material would not also foam in lower head bottom,
Cylinder squeezes offset in liner, increases the stability of equipment, moreover it is possible to ensure the dosage of foamed material.
In the present embodiment, the outer ring edge in annular stop portion is folded upward at, and forms a corral plate, coaming plate and shell
Bottom end opening is fixedly connected.
In a preferred embodiment, the coaming plate in annular stop portion is enclosed in the outside of 1 bottom end opening of shell, so foams
Material will not be overflowed to outside.For better location and installation, a circle location indentations have been set in the outer wall of 1 bottom end opening of shell,
The inner wall of coaming plate is bonded with the outer wall of location indentations.Coaming plate is fixedly connected or is used by screw with the opening of 1 bottom end of shell
Welding manner is fixedly connected, and can also be fixedly connected using some buckle structures.
Wherein, lower head 3 and cylinder 2 in liner are fixed together by welding manner.
The present invention is also mentioned that a kind of water tank, which includes above-mentioned water tank lower head structure.The top of cylinder 2 in liner
A upper cover 5 is also set, it is cylinder 2 in sealing inner container.
Wherein, the top of shell also is provided with being open, by the opening on 4 closure tops of upper capping, in the outer of upper capping 4
A circle attachment recess also is provided on wall, the inner wall of the top end opening of shell 1 is bonded with this attachment recess, and facilitate the two to install,
Fixed form can be adopted to be screwed, be welded and fixed or buckle and is fixedly connected.It is additionally provided between upper cover 5 and upper capping
Spacing, this is for placing some other components of water tank, these are the prior arts, are not just repeated them here herein.
Wherein, cylinder 2, upper cover 5 and lower head 3 are combined into liner component in liner, and shell 1 and upper 4 groups of capping are combined into
Casing assembly, the foamed material that water tank uses just are located between casing assembly and liner component.It is direct using lower head 3 and shell 1
It is fixed together, lower head also plays the effect of lower cover plate, has prevented the inside that foamed material enters lower head, while can also
To play the role of positioning, it is therefore prevented that be located at the offset of the pipeline in liner component due to caused by foaming.
The present invention also protects a kind of water heater including above-mentioned water tank.
Above by specific embodiment, invention is explained in detail, these detailed description are only limited to help ability
