Description
Technical field
The utility model relates to electric heater, especially a kind of quick-heating type electric water heater with phase-change material.
Background technology
At present, electric heater is divided into heat storage type, Instant heating type, fast heating type three kinds usually, and heat storage type input power is less, but volume is large, takes up room large, and heavier-weight after water storage, require higher to installation metope; Instant heating type i.e. boiling water instant heating, volume is little, takes up room little, but its input power is large, requires high, can not install and use in most civilian place power circuit; And quick-heating electric water heater has certain moisture storage capacity, be generally 6L-30L, but its input power also will reach 3500W-6000W, although quick-heating electric water heater combines some advantages of heat storage type and immediately heating water heater, but its input power is still larger, still can not use in place at home at some, therefore all there is certain limitation in this several electric heater in use.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of quick-heating type electric water heater with phase-change material, and it can export more hot water amount in small volume, input power less, effectively promotes the scope of application of electric heater.
For achieving the above object, the technical solution of the utility model is: a kind of quick-heating type electric water heater with phase-change material, comprise housing, the centre of housing accommodates at least one inner bag, water inlet pipe to stretch in housing and is looped around the periphery of inner bag from housing, water inlet pipe one end be in housing is communicated with the inner space into inner bag, and at least one electric heating tube is equipped with in the inner space of each inner bag, and the inner space of inner bag is also communicated with outlet pipe; Between the outer surface and the inner surface of housing of inner bag, be filled with phase-change material, this phase-change material can higher than during phase transition temperature from solid state transformed be liquid, this phase-change material can lower than being solid-state from liquid conversion during phase transition temperature, and this phase transition temperature is 30-90 ° of C.
Further, described inner bag other parts except top are all coated in housing, and the top of inner bag connects outlet pipe, and the bottom of inner bag connects water inlet pipe.This structure facilitates installation and the replacing of electric heating tube and temperature sensor.
Preferred described housing is square, and described inner bag is cylindrical.
Further, described hull outside is coated with heat-insulation layer or is provided with heat-insulation layer on the wall of described housing.To improve heat insulation effect.
Preferred each inner bag is built with an electric heating tube or two electric heating tubes or three electric heating tubes.
Further, the temperature sensor of water temperature detection is also provided with in each described inner bag.To facilitate the work controlling electric heating tube.
Preferred described phase transition temperature is 40-60 ° of C.
The midfeather of preferred described housing accommodates two inner bags, and water inlet pipe one end be in housing is communicated with the inner space into two inner bags simultaneously, and the inner space of two inner bags is communicated with outlet pipe simultaneously.Heat transfer effect can be improved further like this.
The utility model owing to carrying out heat accumulation under the state not using hot water, electric heating tube not only feeds water heat accumulation of heating, simultaneously heating of electric heating tube impels phase-change material to become liquid from Solid State Transformation by the heat transmission of water, and phase-change material absorbs and stores a large amount of latent heat in fusion process.When needs use hot water, cold water first carries out heat exchange by water inlet pipe and phase-change material, because the temperature of now cold water is lower than the phase transition temperature of phase-change material, phase-change material can be progressively solid-state from liquid conversion, a large amount of latent heat treatment in water, water is heated when entering inner bag, is subject to again the heating of electric heating tube when then entering inner bag, and such water heater just can export hot water the long period.Therefore the utility model can export more hot water amount in small volume, input power less, combine the advantage of heat storage type and quick-heating electric water heater, namely there is less volume, what only need input again that less power just can meet people uses water requirement, and it effectively promotes the scope of application of electric heater.

Detailed description of the invention
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in further detail.
Shown in Fig. 1 to Fig. 5, a kind of quick-heating type electric water heater with phase-change material, comprise housing 1, the midfeather of housing 1 accommodates two inner bags 2, water inlet pipe 3 to stretch in housing 1 and is looped around the periphery of two inner bags 2 from housing 1, water inlet pipe 3 one end be in housing 1 is communicated with the inner space of two inner bags 2, water inlet pipe 3 connects the bottom of two inner bags 2 simultaneously, one to three electric heating tube 4 can be installed as required in the inner space of each inner bag 2, three electric heating tubes 4 are housed shown in figure, so that more flexible control inputs power, the inner space of two inner bags 2 is also communicated with outlet pipe 5, outlet pipe 5 connects the top of two inner bags 2 simultaneously,
Phase-change material 6 is filled with between the outer surface and the inner surface of housing 1 of inner bag 2, this phase-change material 6 can higher than during phase transition temperature from solid state transformed be liquid, this phase-change material 6 can lower than being solid-state from liquid conversion during phase transition temperature, this phase transition temperature is 30-90 ° of C, and preferably this phase transition temperature is 40-60 ° of C.
For meeting the phase-change material 6 that phase transition temperature is 30-90 ° of C, this phase-change material 6 can select the material such as paraffin, hypo, and the selection of phase-change material 6 is primary Consideration with safety in utilization.
Two inner bags 2 other parts except top are all coated in housing 1.
Preferred described housing 1 is square, and described inner bag 2 is cylindrical.
Heat-insulation layer 7 is coated with in described housing 1 outside; Also on the wall of housing 1, directly heat-insulation layer can be set.
The temperature sensor of water temperature detection is also provided with in each described inner bag 2.To facilitate the work controlling electric heating tube 4.
Operation principle of the present utility model is: do not using in hot water situation, electric heating tube 4 heats to the water of inner bag 2, when the temperature of water meets or exceeds the phase transition temperature of phase-change material 6, impel phase-change material 6 to become liquid from Solid State Transformation by the heat transmission of water, phase-change material 6 absorbs and stores a large amount of latent heat in fusion process.
When needs use hot water, cold water first carries out heat exchange by water inlet pipe 3 and phase-change material 6, because the temperature of now cold water is lower than the phase transition temperature of phase-change material 6, phase-change material 6 can be progressively solid-state from liquid conversion, a large amount of latent heat treatment in water, water is heated when entering inner bag 2, the heating of electric heating tube 4 is subject to again when then entering inner bag 2, such water heater just can export hot water the long period, what meet people uses water requirement, can also have less volume and less input power simultaneously.
Below be only the utility model preferred embodiment, those skilled in the art makes by claim the protection domain that equivalent change all falls into this case.
