The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Shown in seeing figures.1.and.2, present embodiment has the inner container of electric water heater 1 of novel heating tube mounting structure, comprise water inlet pipe 2, outlet pipe 3, heating tube mounting flange 4, bottom heating tube 5, top layer heating tube 6 and temperature tube 9, bottom heating tube 5 inside are provided with cold pin 10 of bottom heating tube and bottom heating tube heater strip 11, top layer heating tube 6 inside are provided with cold pin 7 of top layer heating tube and top layer heating tube heater strip 8, and top layer heating tube 6 and bottom heating tube 5 are installed on the heating tube mounting flange 4.Top layer heating tube 6 is used for heating synchronously the water body of soon exporting around outlet pipe 3 tops, improve leaving water temperature, the mounting structure of present embodiment heating tube is consistent with conventional heating tube mounting structure, adopt the mode of heating tube mounting flange 4 to install, certainly also can adopt spiral shell head mounting means, while installing bottom layer heating tube 5 and 6 two heating tubes of top layer heating tube on the heating tube mounting flange 4 also can heat needs according to reality certainly many heating tubes are installed.Its temperature measurement fraction adopts heating tube temperature tube 9 to carry out, and temperature tube 9 is arranged separately on the heating tube mounting flange 4, so, can select point for measuring temperature flexibly, can thermometric be installed in desired location, and point for measuring temperature can be determined also according to actual conditions.
With reference to shown in Figure 1, bottom heating tube 5 is the flat Z font of bending, and the terminal 5-1 of body is the hook solid that is bent upwards, thereby makes bottom heating tube 5 for single layer structure, for the space has been saved in the installation of top layer heating tube 6; Top layer heating tube 6 comprises the non-heating 6-2 of portion and is connected in the 6-1 of heating portion of the terminal 6-3 of non-heating portion that the non-heating 6-2 of portion is with bottom heating tube 5 be arranged in parallel and terminal upwards bending setting.So, because the non-heating part 6-2 of top layer heating tube 6 is with bottom heating tube 5 be arranged in parallel or intimate be arrangeding in parallel, shape is close, make whole heating-pipe structure compactness, top layer heating tube 6 and bottom heating tube 5 can be installed in the inner bag in the perforate of an end socket, reduce perforate, reduced the probability that leaks, guaranteed product quality.
Be to increase the heating surface (area) (HS of top layer heating tube 6, improve and add heat, the 6-1 of its heating portion is shape in the shape of a spiral, be looped around outlet pipe 3 in the inner bag 1 around.
The 6-1 of heating portion of top layer heating tube 6 can adopt with a kind of tube material with the non-heating 6-2 of portion or adopt different materials to make, for saving material cost, in the present embodiment, the 6-1 of heating portion can adopt the good stainless steel pipe of the higher corrosion resistant performance of nickel content, the non-heating 6-2 of portion is because major part is temperature or low temperature pool in being in, and self does not generate heat, only play the effect of supporting the heating 6-1 of portion and with the cold pin 7 of inner top layer heating tube, the effect that top layer heating tube heater strip 8 and outside water body insulate, can adopt nickeliferous lower common stainless steel tubing to make, greatly reduce the cost of manufacture of heating tube.
The 6-1 of heating portion of top layer heating tube 6 and the non-heating 6-2 of portion adopt the mode of laser butt welding to be fixed on integrally formed whole heating tube in the present embodiment, certainly, also can adopt other mode that is connected, and present embodiment does not limit this.
Because the 6-1 of heating portion of top layer heating tube 6 concentrates on the top of outlet pipe 3, for what satisfy product is thermal effect, the cold pin of top layer heating tube 7 is long, run through non-heating part 6-2 always, extend to the junction of non-heating part 6-2 and the 6-1 of heating portion, just begin that welding arranges on the cold pin 7 of top layer heating tube and run through the top layer heating tube heater strip 8 of heating part 6-1, the effect that the cold pin 7 of top layer heating tube plays energising and supports, top layer heating tube heater strip 8 is a heating element heater, can make heat more concentrate on delivery port like this, improve leaving water temperature.
Present embodiment has also proposed to be equipped with the electric heater of inner container of electric water heater described in the present embodiment 1, the be installed as routine of inner container of electric water heater 1 on electric heater installed, the concrete structure of inner container of electric water heater 1 can not repeat them here referring to the record of embodiment and accompanying drawing 1 and Fig. 2 of the inner container of electric water heater that the utlity model has novel heating tube mounting structure.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
