Abstract
The utility model discloses a phase-change thermal-storage type electric water heater which comprises a water heater shell. Thermal insulation materials are disposed in the water heater shell. A plurality of containers are arranged in the water heater shell. The containers are respectively filled with phase-change materials. A heat exchanger tube is embedded in the phase-change materials in each container. One end of the heat exchanger tube is connected with a water inlet pipe. The other end of the heat exchanger tube 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 installed in the water container. The circulating pump and the electric heater are respectively in electric connection with a controller. The controller is fixed on a shell of the electric heater. Through utilization of high heat accumulation property of the phase-change materials, the phase-change thermal-storage type electric water heater can accumulate heat in advance, can supply hot water for users anytime and anywhere and is large in hot water output, safe and reliable. Moreover, the hot water can be kept for a long time.
Description
Technical field
The utility model relates to field of water heaters, concrete relates 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.
The utility model content
To the deficiency of above-mentioned prior art, the purpose of the utility model provides a kind of hot water longer duration, and 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 utility model 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 on the said outlet pipe at the bottom of the current and close, 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.
The operation principle of the utility model 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:
The phase-change thermal storage type electric heater of the utility model 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 the utility model technical scheme; In order more to know the technological means of understanding the utility model; And can implement according to the content of specification, below this patent is elaborated with the preferred embodiment and the conjunction with figs. of the utility model.
