Abstract
The utility model relates to a water storage electric water heater, which comprises a casing, a water storage inner liner, a water inlet pipe, a water outlet pipe and an electric heating pipe, wherein, two hemisphere-shaped shell covers are welded with each other to form the water storage inner liner; the two hemisphere-shaped shell covers are only provided with a strip of circumferential welding seam; the water storage inner liner is generally oblate; the electric heating pipe is aslant arranged in the water storage inner liner. Because the two hemisphere-shaped shell covers are welded with each other to form the water storage inner liner, the welding seam of the water storage inner liner is two fifthes less than an ordinary inner liner and the utility model has the advantages of improvement of production efficiency, good manufacturability and reduction of rate of water leakage. Because the inner liner is oblate, space occupation is smaller and relative capacity is larger.
Description
The utility model relates to a kind of water-storage electric heater.
Existing water-storage electric heater kind is more, and structure is different.Its inner bag is welded by the end socket and the middle cylindrical barrel body at two ends mostly, and three above weld seams are generally all arranged.Its manufacturability is relatively poor, and productivity ratio is lower, and water leakage ratio is higher, and service life is not long.
The purpose of this utility model aims to provide a kind of good manufacturability, weld seam is few, water leakage ratio is lower water-storage electric heater, to overcome the deficiencies in the prior art part.
A kind of water-storage electric heater by this purpose design comprises shell, water storage inner bag, water inlet pipe and water outlet pipe and electrothermal tube, and its architectural feature is that described water storage inner bag is that two hemispherical end sockets are welded, and two hemispherical end sockets only have a circumferential weld.
Described water storage inner bag is generally the oblate spheroid shape, and its cross section is dolioform.Described electrothermal tube is obliquely installed in the water storage inner bag.
Because this water storage inner bag is that two hemispherical end socket solders side form, its weld seam only has one, lacks more than 2/5 than common inner bag, and production efficiency improves, and manufacturability is better, greatly reduces water leakage ratio.This inner bag is the oblate spheroid shape, and institute takes up space less, and relative capacity is bigger.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is that an example structure master looks schematic diagram;
Fig. 2 is the right TV structure schematic diagram of Fig. 1.
Referring to accompanying drawing, this electric heater is positive for being similar to Ω shape, and the below is provided with water inlet pipe and water outlet pipe 6,5.Inner bag 3 is welded by two and half oblate spheroid end sockets, and its cross section is dolioform, and water inlet pipe one side of electrothermal tube 4 from tilting and be arranged on inner bag down is provided with heat-insulation layer 2 between shell 1 and the inner bag 3.7 is described weld seam among the figure, and 8 is excessive line.
The front of this electric heater can also be C shape, circle or other geometry.
