Abstract
The invention discloses a phase-change heat storage type electric water heater which comprises a water heater shell. A heat insulating material is arranged in the water heater shell; the water heater shell internally comprises a plurality of containers; a phase-change material is filled in each container; a heat exchange pipe is embedded in the phase-change material; one end of the heat exchange pipe is connected with a water inlet pipe, and the other end of the heat exchange pipe is connected with a water outlet pipe; a water return pipe is connected between the water inlet pipe and the water outlet pipe; a circulating pump and a water container are arranged on the water return pipe; an electric heater is mounted in the water container; the circulating pump and the electric heater are electrically connected with a controller respectively; and the controller is fixed on the water heater shell. The phase-change heat storage type electric water heater disclosed by the invention mainly utilizes the high heat storage property of the phase-change material to store heat in advance, can provide hot water for users anytime anywhere, realizes long duration and large amount of the hot water, and is safe and reliable.
Description
Technical field
The present invention relates to field of water heaters, concrete relate to a kind of phase-change material heat storing type electric water heater.
Background technology
Existing phase-change material heat storing type electric water heater is because the demand of using, and it is bigger that internal capacity is provided with, and the water heater internal capacity causes the phase-change material over-deposit after excessive easily, thereby influences the entire effect performance of water heater.
Summary of the invention
To the deficiency of above-mentioned prior art, the purpose of this invention is to provide a kind of hot water longer duration, hot water output is many, safe and reliable phase-change thermal storage type electric heater.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of phase-change thermal storage type electric heater comprises an outer cover of water heater, is provided with insulation material in the said outer cover of water heater; Include several containers in the said outer cover of water heater, be filled with phase-change material respectively in described several containers, be embedded with heat-exchange tube in the said phase-change material; One end of said heat-exchange tube is connected with water inlet pipe, and the other end is connected with outlet pipe, is connected with a return pipe between said water inlet pipe and the said outlet pipe; Said return pipe is provided with circulating pump and water receptacle; In the said water receptacle electric heater is installed, said circulating pump is electrically connected a controller respectively with said electric heater, and said controller is fixed on the said outer cover of water heater.
Further, be laid with temp probe on the said outlet pipe, said temp probe is electrically connected said controller.
Further, also be provided with a water flow switch on the said outlet pipe, said water flow switch is electrically connected said controller.
Further, on said water inlet pipe, outlet pipe and the return pipe check valve is installed all.
Operation principle of the present invention is following:
When temperature was lower than setting value, controller started circulating pump and electric heater, and water circulates in pipeline and heat exchanger, and heat transferred phase-change material and storage, temperature reaches the setting value circulating pump and electric heater quits work.During water, cold water gets into heat exchanger through water inlet pipe and is heated, and flows out from outlet pipe to supply the user to use, and flowing backwards appears in the anti-sealing of each check valve, and circulating pump and electric heater were in off working state when water flow switch can guarantee water.
Technique scheme has following beneficial effect:
Phase-change thermal storage type electric heater of the present invention mainly utilizes the high heat storage property of phase-change material, behind the heat accumulation, can hot water anywhere or anytime be provided to the user in advance, the hot water longer duration, and hot water output is many, and is safe and reliable.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. this patent is elaborated.
