Description

Electric heater with water-purifying function

The utility model is a kind of multi-functional electric heater, can realize easily to water filter, heat, multiple function such as magnetization.

Existing document has openly been reported various electric heater, as Chinese patent 85201132 disclosed water heaters, is that the electrode that utilization is embedded in the water is that heater heats with water.When this water heater used, the electrode in the water can corrode because of electrolysis, and the life-span is short, and used in the bad place of some water quality, and also may produce some harmful substances influences health.As imperfect earth, water is with charged and bring safety problem, and function singleness, only water can be heated.And the electric heater of selling on a lot of existing markets, as be embedded in the electric heater that the heating wire in the water heats, because heating wire is easy to damage, insulation inconvenience processing, short, shortcomings such as security performance is low, function singleness of life-span are arranged.The heat storage type water heater uses inconvenience, can not obtain hot water very soon, and cold and hot adjusting is inconvenience also, and the hot water service amount is limited.

The purpose of this utility model is: a kind of multi-functional water heater is provided, when adding hot water, water is filtered, purifies, magnetizes, obtain the magnetization cleaned easily hot water.

The utility model passes through structure cleverly, utilizes the principle of induction of alternating magnetic field, the magnetic field that induced current produced that has utilized the filter line to induct on high-gradient magnetic field that is produced under the background magnetic field effect and filter line simultaneously.Its basic principle is that the filter line forms the loop in an alternating magnetic field, at first, as a kind of magnetic conduction fine rule, can form high-gradient magnetic field around it; Secondly,, can produce induced potential and form electric current, obtain induced current magnetic field as a kind of galvanic circle, these two magnetic fields can actings in conjunction in particle.And this phenomenon is called high gradient induced magnetism separation principle.

Through deriving, the field intensity that the coil that number of turn is W produces in air gap is:

In the formula, supposing that magnetic pressure is fallen all falls on air gap L---air-gap length, μ _O---the magnetic permeability in the vacuum.

Background magnetic field can be expressed as the active force of particle:

F _mrb＝－ (X _PV _PMa ²)/(r ³) （Ma ²／2μ _Or ²＋HCOS2θ）

F _mθb＝－ (X _PV _PMa ²)/(r ³) HSin2θ

In the formula: M=(μ-μ ₀)/(μ+μ ₀) 2 μ ₀H

X _P---------particle is apart from the distance of filter line for the magnetic permeability a of filter line---filter line radius r---for the volume μ of particle for particle magnetic susceptibility Vp.

The electric current that filter is responded on the line loop, consider that influence each other (only considering two loops, the similar consideration in a plurality of loops) between the filter line loop can show to be:

＝－ ((jωM _C1Z ₂+ω ²M _C2M))/(Z ₁Z ₂+ω ²M ²)

＝－ ((jωM _C2Z ₁+ω ²M _C1M))/(Z ₁Z ₂+ω ²M ²)

In the formula, M _C1, M _C2Be of the mutual inductances of two filter line loops to coil, Z ₁, Z ₂The self-impedance of expression secondary circuit, M are the mutual inductance between two filter line loops, and ω is a supply frequency, and I is a coil current.

The magnetic field that induced current produces can be expressed as the active force of particle:

F _mril＝－μ _OX _PV _P( (|Y ₁|LH _mSin(ωt+θ _C))/(2πW) ) ²1/(r ³)

In the formula, | Y ₁|=I ₁/ I ₂The amplitude of transfer voltage, the i.e. ratio of induced current and input current.Therefore, the total magnetic force that acts on particle is:

F _mr＝F _mrb＋F _mri1

F _mθ＝F _mθb＋F _mθil

This shows that the magnetic force of filter line charmed particle is two sums, has strengthened the magnetic separating effect.The filter line forms the loop in alternating magnetic field, produce eddy current on it except strengthening magnetic force, also will produce heat, can be used.

The utility model---have the electric heater of the function of purifying waste water, form by institutes such as coil 1, conduit 2, filter line 3, magnetic circuit 4, magnetic conduction baffle plate 5, electrical insulation pad 6, end-fitting 7, seal washer 8, shells 9.As shown in Figure 1, coil 1 is around on the conduit 2, can add one deck insulation spacer 6 between coil 1 and conduit 2 in order to insulate better.Filter line 3 places among the conduit 2, and two ends are blocked with magnetic baffle plate 5.Magnetic circuit 4 is enclosed in coil 1 outside and is supported by conduit 2, has attacked screw thread so that connect on it adding an end cap 7 above the conduit 2 simultaneously.Shell 9 is added on outside the magnetic circuit 4 and supports with conduit 2.Between end cap 7 and conduit 2, add upper sealing washer 8 to prevent that hot water spills in the conduit 2.

Coil 1 feeds alternating current and produces the alternation background magnetic field among Fig. 1, and this magnetic field will form high-gradient magnetic field inductive loop simultaneously on the loop that filter line 3 is formed.2 in conduit supports buffer action, and for fear of magnetic screen and eddy-current heating, the most handy non-magnetic conduction, non-conducting material are made.Filter line 3 is the key elements that filter and add hot water, places conduit in any way, and constitute can be effectively loop by electric current.In order to raise the efficiency and prevent that the alternation magnetic dispersion to metal object heating on every side, preferably using high permeability material to make magnetic circuit 4.For avoiding inductive loop heating in the magnetic circuit, use thin slice and repeatedly be pressed into magnetic circuit.The laminate patch mode should make magnetic direction and laminate patch plane parallel, can directly roll up repeatedly and the width of cloth is penetrated repeatedly pressure of formula, (being that the roll type and the width of cloth are penetrated formula), directly volume is used alternately thin slice and is rolled into cylinder from level to level and gets final product, radiation-like laminate patch mode forms along circumferentially repeatedly pressing with broad sheet as shown in Figure 2, and its laminate patch shape can be the plane and also can be curve form.Simultaneously, leak into magnetic circuit, be preferably in the magnetic circuit outside and add closure 9 for anti-sealing.Be shaped on one linedly blocking the filter line on the conduit, bore a little Kong Rangshui on it and pass through, simultaneously, for raising the efficiency the minimizing leakage field, respectively put a magnetic conduction baffle plate 5 in that the filter line is upper and lower, shown among Fig. 15, also should be drilled with water hole on it, shell 9 is double as magnetic circuit 4 simultaneously.

The utility model is on constituting, and for the ease of cooling with improve the heat efficiency, except that with the air natural cooling, coil can adopt water-cooling pattern, and water earlier by coil, is taken away in the conduit that reinjects behind its heat and handled.Can take hollow conductor coil internal water cooling mode, promptly coil is by the hollow conductor coiled, and water flows through in lead and cools off.Also can adopt the mode that adds cooling water pipe, as shown in Figure 3,10 expression cooling water pipes among the figure, it is cylindric to be about to the water pipe coiled made than good material with heat conductivility, and tightly is enclosed within the coil outside.Or the coiled cake is placed on next door, one deck coil one deck water pipe.Before a kind of type of cooling cooling effect better, economical with materials relatively, but complex process, insulating reliability are not high, leak easily, leak electricity.A kind of mode in back is more with material, but technology is simple, and the insulation safety problem more easily solves.

Filter line of the present utility model should be made broad understanding, in different purposes different shapes can be arranged.The utility model is mainly used in when filtering purpose, and the filter line mainly is to form high-gradient magnetic field and separates magnetic force and filter effect with the generation induced field to improve, and at this moment, the filter line should be very thin thread, and uses composite material etc., to avoid heating as far as possible.When the utility model during as the device of heating, filtered water, the filter line is preferably the thicker annular that has sharp corners or thread (as vehicle chip shape etc.), so that can form high-gradient magnetic field with water filtration, can produce a large amount of eddy current heat again.The utility model is as using in the place preferably in water quality, and filtering function is less demanding, mainly is to add hot water, then filters the metallic object that line can be an arbitrary shape, as long as can produce a large amount of eddy current heat at once.

Analyze by front high gradient induced magnetism separation principle, it is big that the additional magnetic force that induced current produces on the filter line loop behind the feeding alternating current in the coil 1 makes the utility model separate water filter to the absorption affinity of harmful particles such as bacterium than general High-gradient Magnetic, filter effect is better, simultaneously, the high temperature that induced current produces on the filter line has killing action to the bacterium that is adsorbed on the filter line, bacterium in the water will almost all be eliminated, line cleans after filtration, water after the heating, owing to be among the magnetic field, the dynamic magnetization of high-intensity magnetic field will be subjected to, and get magnetized drinking water, proved that medically magnetized drinking water is to calculus diseases, hypertension has certain auxiliary curative effect.

The utility model is multiple functional, has realized originally wanting three of electric heater, filter, water mangetizers etc. to install the function that could realize simultaneously, in the operation operation, all is better than existing these three devices on cost and the treatment effect.The utility model adopts the high gradient induced magnetism to separate to separate with general High-gradient Magnetic water filter to compare the ability of the ability of granule for absorbing, kill bacteria and all is greatly improved.Experimental results show that with the utility model and handle almost germs such as the bacillus in the clear water, Escherichia coli fully of water, and some are stored in metal and compound and some organic matters in the water with the molecule form.The utility model is compared with the electric heater that Chinese patent 85201132 is addressed does not have electrode corrosion to influence problems such as life-span generation undesirable substance, the utility model water power is isolated, has been stopped basically existing water heater ubiquity defective insulation fully and the charged problem that jeopardizes personal safety of water that reason such as improper produces is installed, and compare with present commercially available water heater, piece together and to have abandoned the heating wire that easy oxidation blows and greatly prolong useful life.
