The slim inner container of electric water heater of single courage
Technical field
The utility model relates to a kind of water-storage heater, especially belongs to the slim inner container of electric water heater of single courage.
Background technology
Inner container of electric water heater cross section in the market has three kinds: single round, two round, " 8 " fonts.Close with the utility model is single round single courage electric heater, and its manufacturing process is simple, and rate of thermal water utilization is higher, but this product design is single, and the exterior cross-section length-width ratio is 1:1, and it is big that therefore the area that takes up room is installed, and is unfavorable for promoting the use of.
Summary of the invention
The purpose of this utility model is to provide a kind of single courage slim inner container of electric water heater, and not only manufacturing process is simple to make inner container of electric water heater, and length-width ratio design in product design cross section can arbitrarily change, and therefore has the little characteristics of area that take up room of installing.
Technical solution adopted in the utility model is: it comprises inner bag, heat-generating pipe interface, water inlet, delivery port and sewage draining exit on the inner bag, it is characterized in that, inner bag comprises oval-shaped middle tube and end cap, on middle tube, be shaped on siphunculus, stiffener is equipped with in middle tube both sides, and stiffener is to be fastenedly connected by the connector that runs through siphunculus.
The beneficial effects of the utility model are: the maximum characteristics of the utility model book type be with not all right become feasible.With the cross section is that ellipse is done in the inner bag the many people of tube and wanted to try, but because the electric heater national standard requires inner bag pressure-bearing minimum be 1.2Mpa, big hydraulic pressure like this easily causes inner bag to be out of shape, and has to abandon.The utility model is exactly the problem that solves in high hydraulic pressure bottom inner container distortion, adopt methods such as welding, riveted joint, bolt compress, utilize stiffener to make inner bag indeformable, thereby electric heater apparent size and technological contradiction have well been solved, prevented the problem of hydraulic pressure rising inner bag distortion effectively, simultaneously also solve the problem that electric heater is blasted, and produced the 4th kind of electric heater-slim electric heater of single courage.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the oval-shaped middle tube profile of the utility model, Fig. 2 is the utility model external structure, it comprises inner bag 1, heat-generating pipe interface 13 on the inner bag 1, water inlet 14, delivery port 15 and sewage draining exit 16, it is characterized in that inner bag 1 comprises oval-shaped middle tube 11 and end cap 12, is shaped on siphunculus 2 on middle tube 11, stiffener 3 is equipped with in middle tube 11 both sides, and stiffener 3 is to be fastenedly connected by the connector 4 that runs through siphunculus 2.
The quantity of siphunculus 2 is 2-5 in the utility model.
Connector 4 described in the utility model is fastenedly connected and is meant and adopts nut 41 to be connected with bolt 42 or adopts rivet to connect or adopt screw to connect or employing is welded etc.
The cross sectional shape of tube 11 also can be shapes such as rectangle, oval shape in addition in the utility model, and these shapes all can reach designing requirement after reinforcing, and help improving the appearance and size of heater, is fit to the installation in less space.
