To achieve these goals, the technical solution of the utility model is:
One one kinds of two heat-exchange system inner bag storage tanks of pressure-bearing type enamel, comprise shell and enamel inner container, heat-insulation layer is provided with between described shell and enamel inner container, described enamel inner container inside is provided with electric heater, the first enamel coil heat exchanger and the second enamel coil heat exchanger, described first enamel coil heat exchanger and the second provided with enamel coil pipe are placed in inner bag bottom, and the port of described first enamel coil heat exchanger and the second enamel coil heat exchanger is all positioned on the sidewall of storage tank.
The bottom of described storage tank is provided with pipe in water, and the top of described storage tank is provided with pipe in water outlet.
In described first enamel coil heat exchanger, flowing is the first circulatory mediator, and in described second enamel coil heat exchanger, flowing is the second circulatory mediator.
The upper port of described first enamel coil heat exchanger is the first circulatory mediator entrance, and lower port is the first circulatory mediator outlet.
The upper port of described second enamel coil heat exchanger is the second circulatory mediator entrance, and lower port is the second circulatory mediator outlet.
Described enamel inner container inside is also provided with magnesium rod.
Described first enamel coil heat exchanger and the second enamel coil heat exchanger are underneath type.
The beneficial effects of the utility model are:
1, the three-source integrated overlayable region of equipment use that makes of solar source heat exchange, the heat exchange of air-source thermal source and Electric heating can be realized more extensive.
2, inner bag and heat-exchanger rig all adopt surperficial enamel technology, longer service life.
3, Two-way Cycle heat-exchange system, can select primary and secondary heat exchange mode, avoids the topical type of single heat exchange bar.
4, Two-way Cycle heat-exchanger rig is placed in inner bag bottom, makes heat exchange abundant, even if single heat source heat exchange also can protect positive sufficient hot water.

Fig. 1 the utility model structural representation.
Wherein, 1 upper cover; 2 water storage casings; 3 low heads; 4 first enamel coil heat exchangers; 5 second enamel coil heat exchangers; Pipe in 6 water outlets; Pipe in 7 water inlets; 8 first circulatory mediator entrances; 9 first circulatory mediator outlets; 10 second circulatory mediator entrances; 11 second circulatory mediator outlets; 12 magnesium rods; 13 electric heating tubes.
Detailed description of the invention
In order to better understand the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the two heat-exchange system inner bag storage tank of a kind of pressure-bearing type enamel, comprise upper cover 1, water storage casing 2 and low head 3, upper cover 1, water storage casing 2 and low head 3 enclose formation storage tank, the inner bag of storage tank is enamel inner container, the outside of storage tank is covered with shell, heat-insulation layer is provided with between shell and enamel inner container, enamel inner container inside is provided with electric heating tube 13, first enamel coil heat exchanger 4 and the second enamel coil heat exchanger 5, first enamel coil heat exchanger 4 and the second enamel coil heat exchanger 5 are placed in inner bag bottom.
First enamel coil heat exchanger 4 and the second enamel coil heat exchanger 5 by two different thermal source system heat supplies, also by the heat supply of same thermal source system to increase existing heat exchange area, can improve heat exchange efficiency.
In first enamel coil heat exchanger 4, flowing is the first circulatory mediator, and in the second enamel coil heat exchanger 5, flowing is the second circulatory mediator.First circulatory mediator and the second circulatory mediator can be different circulatory mediators, also can be same circulatory mediator, when two heat exchangers are by being different circulatory mediator during the heat supply of different heat sources system; When two heat exchangers are by during same thermal source system heat supply being then same circulatory mediator.
The port of the first enamel coil heat exchanger 4 is positioned on the sidewall of storage tank, and the port of its middle and upper part is the first circulatory mediator entrance 8, and the port of bottom is the first circulatory mediator outlet 9.
The port of the second enamel coil heat exchanger 5 is positioned on the sidewall of storage tank, and the port of its middle and upper part is the second circulatory mediator entrance 10, and the port of bottom is the second circulatory mediator outlet 11.
The top of enamel inner container inside is provided with pipe 6 in water outlet, and hot water flows out from pipe in water outlet 6, is provided with pipe 7 in water bottom storage tank, and cold water is injected in storage tank by interior pipe 7 of intaking.
Enamel inner container inside is also provided with magnesium rod 12, magnesium rod is sacrificed in the effect of magnesium rod 12, exchange the stainless steel not consuming storage tank inside for, thus improve service life, this design is based on easy in energising situation, anode ionizes, sacrificial electrode, and when consumption of electrode is complete, whole water heater has also just been scrapped.So adopt magnesium rod to increase service life.
First enamel coil heat exchanger and the second enamel coil heat exchanger are underneath type.
In use, the first enamel coil heat exchanger 4 is connected solar source and air heat source system respectively with the second enamel coil heat exchanger 5, and which thermal source two heat exchangers specifically connect is random.Air heat source system is air source heat pump, utilizes compressor, and it can carry the heat in air.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
