[summary of the invention]
The purpose of this utility model is, provides a kind of and utilized electrical heating to make phase change medium undergo phase transition after the accumulation of heat accumulating type electric water heater of heat release again.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
A kind of accumulating type electric water heater comprises the accumulation of heat casing, control system, and insulation shell is characterized in that being provided with electrical heating elements in the bottom of accumulation of heat casing, and the compact arranged heat accumulation pipe of fixing and supporting with the water distribution chassis by fixedly taking over a business is equipped with at the middle part; Described electrical heating elements is connected with control system, is packaged with the accumulation of heat phase change medium in the heat accumulation pipe, has apopore on fixedly taking over a business, and water distribution has water distributing pore on the chassis, and they are corresponding with the slit between the heat accumulation pipe.
Aforesaid a kind of accumulating type electric water heater is characterized in that being provided with outlet pipe on the top of accumulation of heat casing, and the bottom is provided with water inlet pipe.
Aforesaid a kind of accumulating type electric water heater is characterized in that heat accumulation pipe is a round tube.
Aforesaid a kind of accumulating type electric water heater is characterized in that the accumulation of heat phase change medium is the hydrated inorganic salt.
Aforesaid a kind of accumulating type electric water heater is characterized in that being provided with temperature-sensing element on fixedly taking over a business, and it is connected with control system.
Compared with prior art, the beneficial effects of the utility model are: 1. owing to adopt the 220V single phase poaer supply, consumption of electric power is little, the while compact conformation, volume is less, promptly made full use of the advantage of displacement type water heater and immediately heating water heater and effectively avoided the shortcoming of two kinds of water heaters, be applicable to that family uses; 2. along with the increase gradually of electricity consumption peak load gap, residential electricity consumption time-shared charge system is progressively carried out, the utility model can utilize the accumulation of heat when the low ebb electricity of the big phase change medium of thermal storage density to reduce electricity price, much more like this help reducing the use cost of accumulating type electric water heater, also meet the development trend of rational utilization of electricity with the low ebb electricity.

Fig. 2 is an A-A cutaway view of the present utility model.
[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
A kind of accumulating type electric water heater includes accumulation of heat casing 1, control system 2, when control system 2 energising heating, water enters from the water inlet pipe 3 of the lower end of accumulation of heat casing 1, obtains behind the electrical heating elements 4 of flowing through, the heat accumulation pipe 5 behind the hot water from the outlet pipe 6 of the upper end of accumulation of heat casing 1 to flow out, and uses for the user.
Inner chamber at accumulation of heat casing 1 is equipped with insulation shell 7, and insulation shell 7 is used for hot water is incubated.Bottom surface sections in insulation shell 7 inside is provided with electrical heating elements 4, and electrical heating elements 4 links to each other with the power supply of 220V by control system 2, is used to control electrical heating elements 4 energising heating with control system 2.In the lower end of insulation shell 7 water inlet pipe 3 is housed, water intaking valve 8 is housed on the water inlet pipe 3, regulate inflow by the aperture that turns water intaking valve 8.
Be provided with the heat accumulation pipe 5 of the circle of marshalling in the centre of insulation shell 7 inside, in heat accumulation pipe 5, be packaged with phase change medium, heat accumulation pipe 5 by be installed in insulation shell 7 upper/lower terminals fixedly take over a business 9, the water distribution chassis is 10 fixing, support.Have water distributing pore 12 fixedly taking over a business to have on 9 on apopore 11, the water distribution chassis 10, they are corresponding with the slit between the water pipe 5, and the water of coming in from water inlet pipe 3 is in the water distributing pore 12 on water distribution chassis 10 fills up slit between the heat accumulation pipe 5 like this.On fixed underpan 10, be provided with temperature-sensing element 13, temperature-sensing element 13 is used to detect the temperature of water in the accumulation of heat casing 1, send signal to control system 2 then, control system 2 is according to the signal of temperature-sensing element 13, the state of control electrical heating elements 4,2 default heating begin temperature if water temperature is lower than control system, electrical heating elements 4 begins to heat the water in the accumulation of heat casing 1, carrying out with heating process, water temperature raises gradually, water is the phase-transition heat-storage media of encapsulation in the heat transferred heat accumulation pipe 5, and makes the accumulation of heat of phase-transition heat-storage medium generation solid-liquid phase change.After phase transition process finishes, water temperature further raises, and when water temperature reached the preset stopping heating-up temperature of control system 2, electrical heating elements 4 stopped to heat the water in the accumulation of heat casing 1, phase-transition heat-storage medium in the heat accumulation pipe 5 has all been finished the solid-liquid phase change process like this, and heat-accumulating process finishes.
The material of heat accumulation pipe 5 can be stainless steel, copper, aluminium or plastics etc.
