The specific embodiment
Describe below in conjunction with accompanying drawing, comprise heating water tank 1 in the accompanying drawing, water-storing tank 2, cold water inlet (or water inlet) 3, hot water outlet pipe's (or delivery port) 4, electric heating element 5, (heating wire is arranged in the metal tube, make metal tube and the isolated electrothermal tube 5-1 of heating wire with magnesia powder, nonmetal glass tube exterior surface plating conductive exothermal material, the electrothermal tube 5-2 of water flowing in the pipe, nonmetallic ceramics tube outer surface plating conductive exothermal material, not water flowing in the pipe, dry combustion method electrothermal tube 5-3, by the hollow aluminum section bar that the flowing water passage is arranged more than two, the centre is clamped more than one and is turned to flat dry combustion method heater 5-4 with heating wire, to heating wire be arranged in the metal tube, make heating wire and tube wall dry combustion method electrothermal tube of isolating and the metal tube that water stream channel is arranged with magnesia powder, cast in the electric heating element 5-5 that forms in the aluminium alloy body, the electric heating element 5-6 that forms by PTC thermo-sensitive material ceramic component) controller and display 6, shell and base plate 7, air 8, water 9, tube connector 10 (cold water tube connector 10-1, hot water return pipe 10-2), water pump 11 (pump intake 11-1, pump outlet 11-2), stretching screw 12, upper end cover 13, bottom end cover 14, felt pad 15, one-way cock 16, water-mixing valve 17, aluminium alloy integral cast body 18, metal tube 19, water flow sensing unit 20.
The heating water tank 1 that electric heating element 5 is constituted among Fig. 1 to Fig. 8 is individual components, and function is after the energising work water to be heated; The power of looking setting is different with the environment water temperature, is controlled automatically by controller 6; For example: if the power of electric heating element 5 is 4.8KW, flow 3L/min, then per minute 4.5～5 ℃/KW that can raise; The water that just flows through heating water tank can raise 21 ℃～24 ℃, and when the environment water temperature just can flow out＞40 ℃ hot water water flowing energising back during at 20 ℃ for a long time, water pump cuts out all the time in such cases; When the environment water temperature below 20 ℃ the time, controller can be set to the pattern in winter, after connecting power work, water pump 11 and electric heating element 5 are worked simultaneously, and this moment, water inlet system was closed, water pump can be squeezed into the cold water in the water-storing tank 2 heating in the heating water tank 1, heated water is back in the water-storing tank 2 by hot water return pipe 10-2, and the circulation heating, until reaching design temperature, promptly quitting work, beginning to take a shower this moment can provide for a long time＞40 ℃ hot water; Because the working flow of selected water pump 11 is greater than more than the shower water flow twice, be gondola water faucet 24 when emitting hot water, have＞50% hot water is back in the water-storing tank 2, mixes mutually with the cold water that enters, therefore enter the water of heating water tank 1, basal temperature is all the time more than 20 ℃.
Water-storing tank 2 only is the usefulness of water storage, and its inside does not generally need to install electric heating element; The heating water tank volume only needs hundreds of milliliter to several liters to get final product; The volume of water-storing tank can be accomplished several hectolitres or make several being together in series or parallel from several liters; The relative position of heating water tank 1 and water-storing tank 2 can be provided with arbitrarily, and cross sectional shape is not limit, and is as the criterion to satisfy instructions for use.
The connected mode of water pump has two kinds. Fig. 1. and Fig. 3 to Fig. 8 Figure 10 is to adding boiled water case supply water at low temperature; Fig. 2 injects low-temperature space with high-temperature water, can arbitrarily select for use, but water pump is in low-temperature space work, and the life-span is longer.
Fig. 1 to Fig. 8 product must be equipped with anti-electric wall for guaranteeing safety; Arrow is a water (flow) direction among the figure.
Fig. 8 is that the heating water tank that has can be arranged on the electric heater within the water-storing tank, and two water-storing tanks series connection are used among the figure, and the cold water that heating water tank needs during water pump 11 work, is provided by water pump, when water pump cuts out, directly injects from water-storing tank; This structure is applicable to big capacity hot-water supply, many cover heating water tank can be set or many cover electric heating elements 5 are set in heating water tank, and alternation is to increase the hot water supply and to increase the service life; Heating water tank is a bascule, can be for changeing; If it is also passable that heating water tank and water-storing tank are made as one, within protection domain of the present invention.
