The utility model provides a kind of heating apparatus of electric water heater, wherein, comprising:
One inner bag;
One cold water pipe and a hot-water line, it is arranged in this inner bag;
One heating tube group, it comprises at least one heating tube, and this heating tube group is arranged at this inner bag inner bottom part position; And
One outer cover, it covers at, and this heating tube group is outside, and this outer cover sidewall is provided with several water inlets, and this outer cover top is provided with at least one delivery port.
The described heating apparatus of electric water heater of the utility model, wherein, this cold water pipe and this hot-water line are arranged at this inner bag inner bottom part position, and the length of this hot-water line is greater than the length of this cold water pipe, and this delivery port is adjacent to this hot-water line upper end.
The described heating apparatus of electric water heater of the utility model, wherein, this heating tube is provided with a plurality of, and said heating tube is connected in parallel.
The described heating apparatus of electric water heater of the utility model, wherein, this cold water pipe one end connects one first water pipe head, and this hot-water line one end connects one second water pipe head.
The described heating apparatus of electric water heater of the utility model, wherein, this inner bag bottom is provided with an assembly hole, and this heating tube group is installed on this inner bag via this assembly hole.
The described heating apparatus of electric water heater of the utility model, wherein, this heating tube surface is provided with the heat conduction fin.
The described heating apparatus of electric water heater of the utility model, wherein, said water inlet is located at this outer cover sidewall stage casing and is reached fragment position down.
The utility model can have following useful effect:
The utility model utilizes the principle of natural cooling and heating convection circulation through the setting of outer cover, makes that the delivery port that rises to waterborne after the heating of heating tube group flows out in the outer cover, makes the output hot water that hot-water line can be certain.The setting of outer cover also can form the current that nature is stirred, and forced circulation makes whole courage water uniform temperature preferable, and can promote the efficiency of heating surface.
For further understanding the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing about the utility model, yet shown in accompanying drawing only provide reference and the explanation usefulness, be not to be used for the utility model is limited.

The specific embodiment
See also Fig. 1 and Fig. 2; The utility model provides a kind of heating apparatus of electric water heater, comprises an inner bag 1, a cold water pipe 2, a hot-water line 3, a heating tube group 4 and an outer cover 5, and wherein inner bag 1 is a hollow form container; Its inside can hold the water of desire heating; Inner bag 1 can metal material or non-metallic material process, the material of inner bag 1, shape and structure do not limit, can be in response to the suitable variation of needs.
Heating tube group 4 comprises at least one heating tube 41, and heating tube 41 is an electrothermal tube, and the quantity that heating tube 41 is provided with does not limit, if when a plurality of heating tube 41 is set, those heating tubes 41 is connected in parallel, and those heating tubes 41 can separately be heated, and be increased service life.Heating tube group 4 is arranged at inner bag 1 inner bottom part position, can offer an assembly hole 11 in inner bag 1 bottom, makes heating tube group 4 be able to be installed in the inner bag 1 via assembly hole 11, and modes such as heating tube group 4 screws capable of using are suitable is fixed in inner bag 1.Certainly also can be provided with suitable seal element (figure slightly) between heating tube group 4 and the inner bag 1 seals.
In addition; Also can further be equipped with heat conduction fin (figure slightly) on heating tube 41 surfaces, pass area, concentrate on heating tube 41 surfaces to avoid high temperature in order to increase heat; Under the prerequisite that does not influence hot transfer efficiency; Through reducing heating tube 41 surface temperatures, reduce the purpose that incrustation scale produces to reach, the efficiency of heating surface is promoted.
