Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
See Fig. 1-3, electric heater of the present utility model is vertical structure, comprises main part 10 and electrical store 11.Inner bag is positioned at the main part 10 of water heater, see Fig. 2, electric heater 1, water inlet pipe 2, outlet pipe 3 is had respectively in inner bag, insulation alveolar layer 4 is set between inner bag and outer cover of water heater, owing to being Vertical Heat hydrophone, therefore, ring flange is arranged on inner bag bottom centre position, and the bottom that water inlet pipe and water outlet pipe all passes through inner bag is connected with extraneous water system.As diagram, electric heater is one group of electric heating tube, and electric heating tube at least forms two sections of bendings, thus has enough heating pipe ranges, reaches enough and add heat.In order to simplify heat protocol, being convenient to workman and installing and save production cost, one group of electric heating tube is only set in water heater liner, no longer considers other assisted heating structure.Electric heating tube is arranged on ring flange, and its whole height extends beyond more than the neutrality line of inner bag from ring flange to top, and best scheme is: the setting height(from bottom) of electric heating tube is 3/5 of inner bag height.
The sleeve pipe 5 of a tubular in the outer race of electric heater 1, the wall portion of sleeve pipe is separated by 90 degree the four row through holes 6 that distribute, and is positioned at the even equidistant placement of through hole of sleeve pipe the first half.The open top of sleeve pipe and near the delivery port of outlet pipe, be provided with water retaining cover 7 above the water inlet of water inlet pipe, the cover body of water retaining cover arranged some flow-guiding mouths 8.The cover body of water retaining cover is circular shape, and cover body is provided with via hole and outlet pipe 3 via hole of electric heating tube 5, arranges some dash ribs 9 around the installing hole of the water inlet pipe 2 of cover body downwards.See Fig. 3, the flow-guiding mouth 8 on the cover body of water retaining cover is circular hole, is distributed on cover body in annular array mode.
Design in the heat protocol of this water heater and intake in light perturbations design, we expect that the water temperature left from outlet pipe is all between 65-70 DEG C, makes hot water outlet temperature meet the standard of high output rating.Cumulative cabin structure can make the water body in cabin heat rapidly, and hot water rising and the water mixing at inner bag top, make the water body at top reach more than 65 DEG C, then leave inner bag from the delivery port of outlet pipe.This structure can be avoided being heated to more than 65 DEG C by unified for whole water bodys of inner bag, and the energy waste caused, it can guarantee that the water outlet at inner bag top reaches the requirement of high hot water delivery rate and need only heat the local water body of inner bag, for significant contribution is made in energy-conserving and environment-protective.
Further, cold water is concentrated on the bottom of water heater liner, to reach the effect holding up top hot water with cold water as far as possible.And, we also wish that water inlet flow velocity is lower, are unlikely to the water body of disturbance cold water and then cause hot and cold water to mix reduction hot water water temperature, simultaneously, water body bottom inner bag needs along with newly-increased water inlet is to rising, to guarantee that inner bag bottom can not exist the region that a cold water can not carry out water body replacement.Water retaining cover arc cover meets the pressure regularity of distribution into water, plays positive role to slowing down into the flow velocity of water and pressure.Around water inlet pipe, the bottom surface of cover body arranges downwards many gears water rib, dash rib is be convexly equipped in the column structure on dash cover body diapire, multiple delivery port be in staggered distribution is formed between adjacent dash rib, the dash rib of many rows can make the water body entering inner bag from water inlet pipe slow down further, reduce the kinetic energy of cold water, when water body outwards diffuses out from the delivery port of first row dash rib, stop by the dash rib of second row, delivery port afterwards along second row dash rib both sides flows in the gap of dash rib of next row, after full of twists and turns exhalant canal, current form turbulent flow, flow velocity reduces sharply.
