Abstract
The utility model relates to a flat-shaped intra-cavity of an electric water heater, which is composed of two flat-shaped shells in butt joint with each other; wherein, a fastening pull rod is fixed connected between the two shells; the two shells in butt joint with each other can form the intra-cavity; the direction with large stress inside the flat-shaped intra-cavity is the direction perpendicular to the flat-shaped shells towards the inside; the fastening pull rod between two shells can exactly increase the compressive strength of the shells from the side; thus under the situation that no material thickness is increased, the utility model can ensure the flat plane of the intra-cavity will not be deformed due to excessive stress. The utility model has the advantages of simple structure, easy manufacturing and low producing cost.
Description
1. technical field
The utility model relates to a kind of inner container of electric water heater, particularly a kind of flat inner container of electric water heater.
2. background technology
At present, electric heater kind on the market, style are varied, a feast for the eyes, wherein but the heat storing type electric water heater of multichannel water supply is subjected to increasing consumer's welcome, the overall structure of such electric heater is a cylinder at present, this be since inner bag adopted cylindrical structure, have enough bearing strengths to guarantee inner bag because this structure crushing resistance is even everywhere, processing technology is simple.But when the electric heater of this kind cylindrical structure was installed on the wall, the distance of outstanding metope was bigger, installs and uses inconvenience, and for the less user in space, this shortcoming is just more outstanding, had influenced further popularizing of electric heater.For addressing this problem, the someone has adopted the flat inner bag, but the flat inner bag is when bearing the pressure of water, and all directions are stressed inevitable different, are the sufficient intensity that guarantees inner bag, and main at present by increasing material thickness, production cost can obvious increase like this.
3. summary of the invention
The purpose of this utility model provides a kind of simple in structure, handling ease, flat inner container of electric water heater that production cost is not high.
The utility model is achieved in that it is made up of the butt joint of two shallow shells, is fixedly connected with fastening pull rod between two shallow shells.
Good effect of the present utility model is: two shallow shell butt joints can constitute the inner bag of a flat, and stressed big direction is the outside direction of vertical shallow shell in this flat inner bag, therefore fastening pull rod between the two housings just in time can increase the compression strength of this direction of shallow shell, can guarantee under the situation that does not increase material thickness that the inner bag flat horizontal surface is unlikely stressed excessive and be out of shape.It has simple in structure, handling ease, characteristics that production cost is not high.

Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of the utility model fastening pull rod;
Accompanying drawing 3 is the stereogram of the utility model embodiment 1 shallow shell;
Accompanying drawing 4 is the stereogram of the utility model embodiment 2 shallow shells;
5. the specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1
As shown in drawings, the utility model is made up of 1 butt joint of two shallow shells, shallow shell 1 adopts metal material to be stamped to form, its profile can design according to the need and possibility, fixedly connected fastening pull rod 2 between two shallow shells 1, after fixing pull bar 2, with welding or other modes two housings 1 joint is carried out edge sealing again.Fastening pull rod 2 usefulness metal materials are made, and its quantity can determine according to the capacity and the flat degree of inner bag, can be 1, also can be many, is as the criterion to guarantee the unlikely stressed excessive deformation of flat horizontal surface; For the metal material that prevents fastening pull rod 2 by the water oxidation, be provided with fixing seal plastic sheath 3 at the skin of fastening pull rod 2.The mode of fixedlying connected of fastening pull rod 2 and two shallow shells 1, can be that fixing hole 7 is set on shallow shell 1, fastening pull rod 2 two ends put inserts respectively behind the sealing ring 5 on two shallow shells 1 in the corresponding fixing hole 7, then at shallow shell 1 outer surface with nut with fastening pull rod 2 lockings or rivet tightly; In order further to improve the resistance to deformation intensity of housing 1, housing 1 surface is provided with the prominent muscle 4 of some outward direction projections, the distribution and the shape variable design of prominent muscle 4.
Present embodiment is identical with embodiment 1 basic structure, difference is in order further to improve the resistance to deformation intensity of housing 1, housing 1 surface is provided with some grooves that cave inward 6, and prominent muscle among the distribution of groove 6 and shape and the embodiment 14 is the same to change design.
Claims (4)
