over porcelain tube element into, electrode card 13 is located and is extended outside the round porcelain end socket from counterparty's through hole of porcelain end socket two side pair of parallel and makes things convenient for wire bonds 35, there is a dark shrinkage pool of rectangle at center at circle porcelain end socket, the interior sensor 37 that can put warm element 37 of limit or electronic temp limiter device, this round porcelain end socket is held concurrently be with the temperature control characteristic, eight leads of four electrothermal tubes enter the binding post that is in the terminal box 19 behind terminal box 19 and circumscripted power line 18 lines and all are injected into flexible insulation silicon rubber envelope not, in damp attitude environment, meet the electrical safety requirement to ensure, circuit of the present utility model adopts parallel connection method, as shown in figure 10, live wire in the parallel connection is at first by the temperature limiter 37 in the electrothermal tube, temperature limiter 37 can place in the central fovea sky of round porcelain end socket 36, also can post on the extension shell of the Can of electrothermal tube, live wire by the temperature limiter 37 in the electrothermal tube joins with an electrode card 13 of other three electrothermal tubes successively, another root electrode card 13 in four electrothermal tubes all directly is connected with ground wire, and is apparent, when the electrothermal tube excess temperature, limit warm element outage, the live wire of other three electrothermal tubes is outage synchronously also, makes immersion heater all stop electric heating work, and is apparent, when using this Electric radiant Heating Film parts to work, electric heating not only sees through Can 32 and is absorbed by flowing water, is in electric heating in the porcelain tube element and flows to thick heat-conducting metal rod as the heat conduction of the thin heat-conducting metal rod of the rapid quilt of electric iron principle and also absorbed by flowing water, has improved the thermal efficiency, the employed temperature limiter of the utility model, when adopting controllable silicon or AC sheet, can artificially set temperature-limited value work arbitrarily, make to the utlity model has displays temperature, the function of design temperature or locking temperature, or has the water flowing energising, function of cutting the supply of water and electricity and creepage protection function, the attachment feature of whole AC module controls can be installed in the upper cover 3 of lengthening or split is installed separately synchronously as annex and work asynchronously, and Figure 11 has provided the use illustrative method that immersion heater is placed the plastics clamping frame 42 that is fixed on the body of wall 45, wherein the bright screw of being with of clamping frames 42 activity point of view is controlled in 43 expressions, the miniature gondola water faucet (spray chew) of 44 expression spinnings on effluent pipe mouth 14, apparent, just consist of the type fixed shower device when being folded in immersion heater in the plastics clamping frame 42, when plastics clamping frame 42 becomes the handle of a movable adjusting angle, just consist of " pistol " formula movable sprinkler; When the utility model and micro pump are serially connected in the water circulation system of a band water heater ware, switch on the pump, can make the water in the vessel be recycled heating, the water that is used to solve Trend bathtub heats, the water saving of the washing powder in the washing machine in the clothes is removed, and uses this immersion heater, can also high efficiency crosses water and promptly boils, what become dish-washing machine, water boiler crosses the hot movement of water power, accelerates boiling water and produces speed and realize reducing the purpose of saving of eliminating waste heat.

Advantage of the present utility model clearly, the first is gently little, grammes per square metre surplus its outer labyrinth coenosarc 1 and 2 only has 200, external diameter is only Have about φ 45mm, long less than 200mm, profile is pole body shape, pole is external make things convenient for thermal contraction plastic one deck thermal contraction plastic assure or The plastic handgrip 42 of a movable gyration on sandwiched in the middle of immersion heater increases the convenient use of security and flexible feel, Direct shower nozzle 44 on the spinning on the lower capping outlet pipe 14 is convenient for carrying this immersion heater and hand held uses warm water Or hot water; It two is safety, and the water power of this water heating rod definitely separates, electric strong when particularly adopting the electric heating membrane pipe parts Degree not only reaches and surpasses the UL standard, and ceramic dielectric electric heating membrane pipe element antidetonation and difficult fracture, and security is stable, its institute The hidden danger of the reduction electrical strength that might occur in damp attitude environment all is insulated sealing and seal point all is closed in the housing Mechanical damage can not take place and produces electric leakage hidden danger, the ground protection line in the outer conductor and the electrothermal tube metal in the immersion heater in section Shell overlap joint and male connector connect with electric protective device, have ensured in all its bearings Electrical Safety; It three is electric conversion efficiency height, Follow into the current of heating and absorb heat through the inside that the electrothermal tube outer surface absorbs heat energy rather than the heating of flowing through, fully enlarged hot friendship Change area and heat exchange process, the flowing water that the waste heat of heated hot water will soon be heated fully absorbs in the labyrinth outside have been realized filling The waste heat utilization that divides, thus make the thermal efficiency of this directly-heated type water heater surpass conventional directly-heated type water heater even surpassed Heat storage water heater; It four is thoroughly to have broken away from the application of fibrous insulant in water heater, has realized environment-friendly function; They are five years old That electrothermal tube in this immersion heater selects scope wide, so the replacing of electrothermal tube is owing to adopted the plug-in type installation method to hold very much Easily change, when particularly adopting the electric heating membrane pipe parts, electrothermal tube all needn't be pulled out when changing Electric radiant Heating Film porcelain tube element, as long as draw The porcelain tube electrothermic film element that goes out is wherein changed the silver that a pair of elastic electrode that also will justify the porcelain end socket is aimed at porcelain tube Electric radiant Heating Film termination inwall Has inserted just the electrode layer position; In addition, the cost decrease of this immersion heater, mounting process is simple, as long as outward winding The capping of two ends, all parallel labyrinths just two unimpeded, conveniently rinse and wash down scale removal; In sum, immersion heater not only will The electric heater that replaces heavy and low efficiency, and will be as Miniature water heating movement of new generation, for technological transformation needed the water instant heating (boiling) product of Repeat-heating hot water that maybe needs to circulate repeatedly provides technological transformation convenient, for example as washing machine, dish-washing machine, circulation The important water heating accessory of water Heating bath, water boiler.
