Summary of the invention
Technical problem to be solved in the utility model is that a kind of fast heating type water storage electric heater will be provided, and it has fast thermal effect, and low cost of manufacture.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises inner bag and mixed water valve, mixed water valve is provided with first hot water inlet pipe, inner bag is provided with first outlet pipe, be provided with sleeve in the inner bag, be provided with electrothermal tube in the sleeve, wherein the water inlet port of first outlet pipe is arranged in the sleeve, and the water outlet port of first outlet pipe is communicated with first hot water inlet pipe.
Described cover tube bottom is connected with the inner bag bottom, and sleeve top seal and sidewall are respectively arranged with the limbers in two ends up and down.
Described sleeve is suspended in the inner bag, and sleeve bottom opening, top seal and top are provided with the limbers.
Described first outlet pipe is arranged in the sleeve, and first outlet pipe is parallel with the axis of sleeve.
Described first outlet pipe, sleeve, electrothermal tube are integrated structure connected to one another.
Described inner bag also is provided with second outlet pipe, second outlet pipe is positioned at outside the sleeve, mixed water valve also is provided with second hot water inlet pipe, the second hot water inlet pipe two ends are communicated with second outlet pipe, first hot water inlet pipe respectively, and first hot water inlet pipe is provided with selector valve with second hot water inlet pipe's the position that is communicated with.
Described selector valve is a two position three-way valve.
The level height on described electrothermal tube top is less than the level height of first outlet pipe water inlet port, and the level height at sleeve top is less than the level height at the second outlet pipe top.
Described electrothermal tube is U-shaped electrothermal tube or infrared ray heating tube.
The utility model is compared the beneficial effect that is produced with background technology:
1, because the utility model adopts water inlet port, electrothermal tube with first outlet pipe to be arranged on structure in the sleeve, the water that is heated by electrothermal tube rises in sleeve, and flow out from the water inlet port of first outlet pipe, effectively reducing heat spreads to the sleeve external radiation, thereby reach fast thermal effect, and low cost of manufacture, can also preferentially heat the original water storage of inner bag during the water inlet heating.
Description of drawings
Fig. 1 is first embodiment of the present utility model;
Fig. 2 is second embodiment of the present utility model;
Fig. 3 is the 3rd embodiment of the present utility model.
The specific embodiment
As Fig. 1, Fig. 2 or shown in Figure 3, this fast heating type water storage electric heater, comprise inner bag 1 and mixed water valve 2, mix water valve 2 and be provided with first hot water inlet pipe 21, inner bag 1 is provided with first outlet pipe 11, is provided with sleeve 3 in the inner bag 1, is provided with electrothermal tube 4 in the sleeve 3, the water inlet port of first outlet pipe 11 is arranged in the sleeve 3, and the water outlet port of first outlet pipe 11 is communicated with first hot water inlet pipe 21.The water that is heated by electrothermal tube 4 rises in sleeve 3, enters from first outlet pipe 11 and mixes water valve 2 and outflow.
As Fig. 1 or shown in Figure 2, sleeve 3 bottoms of this fast heating type water storage electric heater are connected with inner bag 1 bottom, and sleeve 3 top seals and sidewall are respectively arranged with limbers 31 in two ends up and down.As shown in Figure 3, sleeve 3 is suspended in the inner bag 1, and sleeve 3 bottom openings, top seal and top are provided with limbers 32.For ease of first outlet pipe 11, sleeve 3, electrothermal tube 4 are installed in the inner bag 1, first outlet pipe 11 is arranged in the sleeve 3 in the utility model, both be arranged in parallel by axis, and first outlet pipe 11, sleeve 3, electrothermal tube 4 are integrated structure connected to one another, before inner bag 1 installation, earlier that the three is affixed, integral installation is to inner bag 1 again.
The level height on electrothermal tube 4 tops is fully just flowed out from first outlet pipe 11 after electrothermal tube 4 heating to guarantee water less than the level height of first outlet pipe, 11 water inlet ports.Electrothermal tube 4 is U-shaped electrothermal tube or infrared ray heating tube.
For improving applicability of the present utility model, making this fast heating type water storage electric heater can be used as common storage-type electric water heater uses, inner bag 1 also is provided with second outlet pipe 12, second outlet pipe 12 is positioned at outside the sleeve 3, mix water valve 2 and also be provided with second hot water inlet pipe 22, second hot water inlet pipe, 22 two ends are communicated with second outlet pipe 12, first hot water inlet pipe 21 respectively, first hot water inlet pipe 21 and second hot water inlet pipe's 22 the selector valve 23 that the position is provided with two-position three way that is communicated with.Rotation selector valve 23 switches water heater between fast heat pattern or general mode, promptly select hot water to flow out from first outlet pipe 11 or second outlet pipe 12.The level height at sleeve 3 tops is less than the level height at second outlet pipe, 12 tops, to guarantee fully to be heated just outflow by electrothermal tube 4 from the hot water that second outlet pipe 12 flows out.
The utility model cooperates electrothermal tube 4, first outlet pipe 11 with sleeve 3, reach and use an electrothermal tube can realize fast thermal effect, also be provided with the mixed water valve 2 of second outlet pipe 12 and selectable water exit mode simultaneously, thereby allow the user can select hot water to flow out from first outlet pipe 11 or second outlet pipe 12.Under the speed heat pattern, the water that is heated by electrothermal tube 4 is rapidly heated and to rising to sleeve 3 tops, and sleeve 3 intercepts hot water and heat thereof to external diffusion, makes the water inlet port 111 of first outlet pipe of hot water in the sleeve 3 flow out inner bags 1; Under the general mode, the water that is heated by electrothermal tube 4 is rapidly heated and upwards rise, structure difference according to sleeve 3, hot water rise to sleeve 3 tops and from the limbers 31 on sleeve 3 tops flow out again to around dissipate heat, or simultaneously some hot water before not entering sleeve 3 to around dissipate heat, flow out inner bags 2 from second outlet pipe 12 at last.Certainly, except that electrothermal tube 4, can also other position in inner bag be installed by other electrothermal tube, with the hot water delivery rate of further raising water heater.The electrothermal tube mean level of traditional electrical water heater is arranged on the inner bag bottom, the cold water that preferential heating enters, and by comparison, electrothermal tube 4 of the present utility model can preferentially heat the original water storage of inner bag.
