Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described。
Embodiment one, referring to shown in Fig. 1 to Fig. 3, a kind of storage-type electric water heater, including water storage liner 1 and water inlet pipe 2, water inlet pipe 2 is positioned at water storage liner 1 inner bottom part, and described water inlet pipe 2 surface is provided with some tap holes 21 along its axis direction。
Described tap hole 21 level is uniform is arranged on water inlet pipe 2 left and right sides。
Described water inlet pipe 2 one end is fixed on a ring flange 6, and water storage liner 1 companion flange dish 6 is provided with opening 11, and ring flange 6 and described opening 11 are tightly connected。
Described ring flange 6 is additionally provided with and adds heat pipe 4 and outlet pipe 5, add heat pipe 4 U-shaped, add heat pipe 4 two ends vertical distribution and be connected with ring flange 6 respectively, add two ends in heat pipe 4 be provided with draw rod 42, two draw and are connected to heating wire 41 between excellent 42 the inners, and two draw excellent 42 outer ends is connected to conductor wire 43；Adding heat pipe 4 to be provided with the part of heating wire 41 and be bent downwardly and sink down into bottom water storage liner 1 to locate, water inlet pipe 2 is positioned to add and bends and extend along adding heat pipe 4 length direction along adding heat pipe 4 below heat pipe 4, and outlet pipe 5 is bent upwards to water storage liner 1 top place。
The described heat pipe 4 that adds is at least provided with two, left and right, and ring flange 6 surface is vertically provided with water out adapter 7 and water supply connector 8 one on the other, and water inlet pipe 2 connects with water supply connector 8, and outlet pipe 5 connects with water out adapter 7。
Described water inlet pipe 2, outlet pipe 5, add heat pipe 4 and be welded and fixed with ring flange 6 respectively。
Being additionally provided with temperature tube 3 on described ring flange 6, temperature tube 3 is positioned at and adds above heat pipe 4。
The inner port of described outlet pipe 5 is provided with 51, and the outlet pipe 5 sidewall near cover plate 51 place is provided with outlet 52。
Described water storage liner 1 is poly chain silicon flexible inner, and due to poly chain silicon flexible inner golden yellow color, we are referred to as " gold silicon inner bag "。Further, since poly chain silicon flexible inner has good insulation, so this patent storage-type electric water heater can also be referred to as " insulation shield water heater "。
Embodiment two, is different in that with embodiment one: referring to Fig. 4, and described water inlet pipe 2 surface is provided with splitter box 22 along its axis direction。Described splitter box 22 is horizontally set on water inlet pipe 2 left and right sides。
The operation principle of the present invention is: water inlet pipe 2 surface of this kind of storage-type electric water heater is provided with some tap holes 21 or splitter box 22 along its axis direction, the cold water entering water storage liner 1 is made to become planar distribution (see B dotted line in Fig. 1 Suo Shi), add below heat pipe owing to water inlet pipe is positioned at, cold water becomes planar distribution and constantly rises (see C arrow in Fig. 1 Suo Shi), hot water is up squeezed by cold water and can discharge from outlet pipe 5 fully, ensure that water heater out be all hot water, water temperature is constant。
For ensureing that gold silicon inner bag performance is to ultimate attainment, this water heater utilizes gold silicon inner bag having the internal pressure free outward expansion of meeting to be adjacent to pressure-bearing steel gallbladder wall (pressure-bearing steel gallbladder is positioned at gold silicon inner bag), pressure-bearing steel gallbladder wall characteristics can be left because self gravitation effect is sagging at the internal no pressure of gold silicon inner bag or negative pressure, (displacement controlling switch can be microswitch can to increase corresponding displacement controlling switch, it is arranged on pressure-bearing steel gallbladder top, the activation button of microswitch stretches in pressure-bearing steel gallbladder and contacts with gold silicon outer surface of liner, when gold silicon inner bag is expanded to a certain degree, gold silicon inner bag touches the activation button of microswitch, microswitch inner contact is in the conduction state；When gold silicon inner bag internal pressure less so that its because of self gravitation effect sagging time, the activation button of microswitch resets, and microswitch inner contact is off；Microswitch can be connected to power circuit or add in thermal management circuit, heating pipe work is controlled) with the break-make by microswitch inner contact, to make anhydrous more accurately or hydropenia surveillance and control measure, thus at utmost improving water heater safety's service behaviour。
For better utilizing the anti-corrosion anti-scale performance of gold silicon inner bag excellence, prevent anhydrous phenomenon to greatest extent, there is water heater liner water backflow phenomenon when the frame for movement that insulation shield water heater also utilizes one-way water inlet valve reliable and stable realizes tap water outside because of municipal administration repairing, avoid the anhydrous work abnormal destruction to water heater to greatest extent；Described one-way water inlet valve can be connected in water supply connector 8。
The acid-fast alkali-proof performance excellent for better applying gold silicon inner bag, high temperature resistant (up to 250 degrees Celsius) and resistance to low temperature (minimum reach-60 degrees Celsius), ensure the work of water heater normal safe, insulation shield water heater installs safety relief mechanism at water outlet end, can better ensure that terrestrial gravitation effect does not deposit downwards blocking pressure relief mechanism and causes that safety relief lost efficacy water heater safety's pressure relief mechanism by low level silt sediment。The safety relief valve being arranged on outlet is made forever to work in the environment of a relative clean free from admixture blocking, to ensure pressure release security performance and lifetime。
The control method of a kind of storage-type electric water heater, when there being water to enter water storage liner, controls to add heat pipe and be heated work with total power, anhydrous enter water storage liner time, water storage liner insulation is set lower than 65 degrees Celsius。
That is, in circuit control program, hot water increase-volume is realized to the full extent for improving insulation shield electric heater, adopting has under flooded condition any, directly control the quick mode of heating heating of total power (being different from industry adopts temperature to drop to the mode that holding temperature 5 degrees centigrade is just heated), temperature controls at 75 degrees Celsius, it is achieved quickly capacity increasing function。Solve the problem that industry electric heater hot water is not enough。
In circuit control program, for solving or eliminate insulation shield electric heater prevent under the service condition of severe water quality region or eliminate the formation of incrustation scale, adopting without under flooded condition, machine internal insulation temperature controls below 65 degrees Celsius, ensures that in machine, incrustation scale cannot be formed to greatest extent。It is different from industry and adopts 75 degrees Celsius of holding temperature modes), it is achieved prevention incrustation scale forms function。Solve the problem that electric heater industry easily produces incrustation scale。
