Described heating tube is fixed on flange, then by fastener, heating tube is fixedly arranged in water storage bag; Described water storage bag water inlet pipe, water storage bag outlet pipe are separately fixed on flange and are communicated with water storage bag inner chamber; Described flow sensor one end is communicated with water storage bag water inlet pipe, and the other end is communicated with outer water inlet pipe, and described tube connector one end is communicated with water storage bag outlet pipe, and the other end is communicated with heat exchanger water inlet end, and described heat exchanger water side and the cross current of going out.
Described interior external heat double-core electric heater, its special character is: on described outer water inlet pipe, be provided with the first temperature sensor, also be provided with controllable silicon, by heat conduction copper part, be fixed on outer water inlet pipe, on described heat exchanger, be provided with the first temperature controller, on described tube connector, be provided with the second temperature sensor, on described outer outlet pipe, be provided with three-temperature sensor, in described water storage bag, be provided with the 4th temperature sensor and the second temperature controller.
Described interior external heat double-core electric heater, its special character is: described heat exchanger comprises shell, aqueduct and several electrothermal tubes, described aqueduct is wrapped in electrothermal tube around, aqueduct one end water inlet end, other end water side, by looping, the die casting aluminium at aqueduct and electrothermal tube outer surface forms described shell, and die casting aluminium connects firmly electrothermal tube and aqueduct to be connected together.
A kind of interior external heat double-core electric heater of the utility model, (one) can make full use of the preheating heat energy in water storage bag.Heat exchanger of the present utility model is arranged at outside water storage bag, and its water inlet end is communicated with water storage bag outlet pipe, and the current lower than 38 ℃ in water storage bag still can continue to use after external heat exchanger heating, until the near 22 ℃ of left and right of water temperature in water storage bag.And in prior art, storage-type or fast heating electric water heater all need hot water in water storage bag and cold water mix to use, the hot water in water storage bag is lower than 38 ℃ during with cold water mix, and user generally can stop using because water temperature is too low.The utility model has overcome in storage-type or fast heating electric water heater prior art, the low problem of heat utilization rate of water storage bag.
(2) the heating tube life-span is long.Heat exchanger of the present utility model, heating tube are the heating module that two covers work independently, and can realize instant heating, two kinds of heating modes of speed heat, and 1 year most of the time, available is heat pattern supplying hot water, and only the minority time need to be used fast heat pattern in the winter time; Be under heat pattern, although heat exchanger longevity of service, its heat-generating pipe is by die casting aluminium quick conductive, low-temperature heat, and non-ly directly contact with water, so scaling not; Although the heat-generating pipe in water storage bag directly contacts with water, the working time is few.And in prior art, storage-type or fast heating electric water heater all need throughout the year with being arranged at the heat-generating pipe work in water storage bag, heat-generating pipe directly contacts with water and produces incrustation scale, causes heat-generating pipe easily bad.The utility model has effectively overcome in storage-type or fast heating electric water heater prior art, and heat-generating pipe need to work long hours and short problem of life-span throughout the year.
(3) installation power is low, is applicable to most of family and uses.The power of heat exchanger of the present utility model and heat-generating pipe is 5500W, by control circuit, can accomplish that heat-generating pipe group only can single startup, can not start, so peak power can not surpass 5500W while using simultaneously.And in prior art, the installation power of instant-heating electric water heater generally will reach 7500W could normally be used in China winter, therefore very high to subscriber's line circuit requirement, general family cannot be used.It is large that the utility model has overcome instant-heating electric water heater installation power, the problem that inapplicable ordinary residence is installed.
