Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring now to fig. 1-10, a phase change water heater 100 according to an embodiment of the present invention is described, as shown in fig. 1, 2, 5, 6 and 8, and as shown, the phase change water heater 100 may generally include: the energy storage device comprises a shell 10, an isolation structure 21, a plurality of functional devices 22 and an energy storage box 30.

Specifically, as shown in fig. 2 and fig. 6, the isolation structure 21 is disposed in the casing 10 and divides the internal space of the casing 10 into a first chamber and a second chamber, the plurality of functional devices 22 are disposed in the first chamber, the energy storage box 30 is disposed in the second chamber, and a thermal insulation material is disposed between the outer wall of the energy storage box 30 and the casing 10.

As shown in fig. 2 in conjunction with fig. 6 and 9, the plurality of functional devices 22 include a heat pipe 227, a water pump 224, a pipeline 225, a thermostatic valve 223, a controller, and the like, the pipeline 225 is communicated with the water pump 224 and the energy storage tank 30, and the water pump 224 is communicated with the heat pipe 227, i.e., the heat pipe 227 is communicated with the energy storage tank 30. Thus, in the first heating phase, the heat pipe 227 is operated during the primary heating phase, since the energy in the energy storage tank 30 does not reach the preset temperature requirement of the hot water. Specifically, when the water pump 224 starts to operate, water flows from the pipeline 225 through the water pump 224, i.e., the heat pipe 227 heats and then enters the energy storage tank 30, and then the water flows into the pipeline 225, and the previous process can be continued until the water flow reaches the preset temperature, and the water flow can flow out from the outlet of the pipeline 225 for the user to use. In the second heating stage, the stored energy of the energy storage box 30 meets the heating requirement, and at this time, the heating effect of the heat pipe 227 can be closed, so that the energy is saved.

It will be appreciated that, in one aspect, the plurality of functional devices 22 have controllers with electronic components therein, and that temperature may have an effect on the useful life of the electronic components. On the other hand, in order to improve the heat utilization rate, the heat emitted from the energy storage box 30 needs to be isolated in the chamber, so as to improve the heating efficiency, and at this time, a heat insulating material needs to be filled between the energy storage box 30 and the housing 10. Because the insulation material is the expanded material, when filling the expanded material, the expanded material gets into in the functional device 22 very easily, and the expanded material has the thermal-insulated effect that keeps warm, and the heat that electronic component etc. sent can't be discharged fast, and the heat accumulation can influence the life of functional device 22. Through setting up isolation structure 21 and keeping apart the inner space of casing 10 to locate different cavities with functional device 22 and energy storage box 30, like this, the heat that energy storage box 30 gived off can not influence functional device 22's life, when filling the filling foam material, also can reduce the probability of leaking the bubble (also the foam fills the bubble to first cavity indoor filling), has reduced functional device 22 self and has generated heat to life's influence, has further improved life.
