Description

Electromagnet water heater

Technical field

The utility model relates to a kind of Instant heating type electromagnet water heater, is fit to industries such as family, school, cosmetology and uses.

Technical background

Chinese patent application file (patent No. 200420022392.3) discloses a kind of electromagnetism medium instant electric water heater.The heating system of this water heater comprises the iron core of annulus column, the primary coil of wound core annulus post limit coiling, cooling water pipe along the external peripheral surface coiling of primary coil, the copper pipe as secondary coil of wound core annulus post limit coiling, the copper pipe two ends connect cooling water pipe and outlet pipe respectively, face mutually between the two circle copper pipes and have the solder joint that can form short circuit, primary coil is by relay and power connection, described copper pipe evenly distributes and is wound on the whole circle iron core annulus post limit, and every circle copper pipe is all with described iron core annulus post limit, the primary coil of coiling and along the cooling water pipe of the external peripheral surface coiling of primary coil inclusion in the lump on the iron core.Though this water heater has its unique novel part, yet the part that still haves much room for improvement.The cross section that mainly is iron core is rectangular, the closed-loop path of the magnetic line of force that this not only makes iron core and is produced is can not smooth circle suitable, influence the efficient of magnetic force power conversion and the efficient that energy utilizes, and the position existence in big gap always arranged during installations such as remaining part such as cooling water pipe, copper pipe location with iron core, be difficult to accomplish and the applying as far as possible of iron core that this has not only also reduced the efficient that energy utilizes, and the product design of making is bigger, the space of occupying is more, has influenced the class of product.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiency that the above-mentioned background technology exists, and a kind of improvement of magnetic water heater is provided, that this water heater should have is simple and reasonable, efficient is higher and easy to manufacture, weight reduces, lower-cost characteristics.

The technical scheme that the utility model provides is: electromagnet water heater, its heating system comprises circular iron core, the primary coil of wound core annulus limit coiling, preheating cooling water pipe along the external peripheral surface coiling of primary coil, the even also copper pipe as secondary coil of coiling that distributes in wound core annulus limit, the copper pipe two ends connect cooling water pipe and delivery port respectively, face mutually between the two circle copper pipes and have the solder joint that can form short circuit, and all with the primary coil of coiling on the described iron core annulus limit and along the cooling water pipe of the external peripheral surface coiling of primary coil inclusion in the lump, the cross section on the annulus limit of described annular iron core is circular to every circle copper pipe.

The inner circumferential surface of described primary coil also is wound with cooling water pipe.

Because circular cross section has been adopted on the annulus limit of annular iron core, the closed-loop path of the magnetic line of force that the is produced smooth circle that becomes is suitable, and the efficient of magnetic force power conversion is able to obvious raising, and iron loss reduces relatively, also makes O sections core obtain better electric property.In addition, take all of closely sliding and do not have knuckle at the primary coil line of this annulus limit coiling, just as R sections core, wire turn is close to iron core, makes Distribution of Magnetic Field even, electromagnetic coupled efficient improve and leakage field still less, fundamentally solved the noise problem of transformer; Also make the insulation of iron core and line parlor properer, more reliable, overcome the difficulty that bring to insulation the square-section of annular core.Moreover because the cross section does not have knuckle, the line system that holds also becomes more free and relaxed, arranges slyness closely, has significantly reduced vibrations; Simultaneously, the circle of line bag and insulating materials is long also can be reduced about 10%, and the range of choice in enamel-covered wire line footpath is free more, and the total consumption of material can be saved 13-30%; The minimizing that circle is long has reduced internal resistance again, has strengthened overload capacity, and the temperature rise of line bag but thereby improve.Should be pointed out that at last the utility model more becomes rationally at technology, structure, cost aspects, cost has tangible reduction.

The specific embodiment

The heating system of this electromagnet water heater shown in Figure 1 is circular, the copper pipe 8 (number of turns of copper pipe coiling can be determined as required) as secondary coil in the even coiling in annulus limit, face mutually between the two circle copper pipes and have the solder joint that can form short circuit, the two ends of copper pipe connect cooling water pipe and delivery port respectively.Two interfaces that show among the figure are respectively water inlet 8-1 and and delivery port 8-2.

Fig. 2, shown in Figure 3 be cross-sectional schematic after heating system is removed copper pipe.Among the figure as can be known: innermost layer be O shape iron core 1, this iron core is annular, its ring limit cross section (A-A section) be the circle, adopt general Digit Control Machine Tool just can make.Surface, iron core ring limit is tied with core insulating tube 6, and the surface of this insulating barrier evenly is wound with primary coil 4 again, then again with the coated line bag insulating barrier 2 of making of insulating materials; Nature, primary coil also can be shaped on some taps 3.Beyond the line bag insulating barrier 2, be equipped with the preheating cooling tube 5-1 that is close to primary coil along the outer annular edge of iron core; Be to improve cooling effect, also can be, be close to primary coil and set up cooling tube 5-2 along the interior ring limit of iron core; These cooling tubes also all turn to circle and are positioned at the annulus limit of iron core; Showing among Fig. 3 has 2 preheating cooling tube 5-1 and 2 cooling tube 5-2 respectively, split around circular cross section, and fixing by fixed band 7.Described iron core ring limit, primary coil 4, all preheating cooling tube and cooling tubes all are close to inclusion by aforementioned copper pipe 8, so that carry out high efficiency magnetic thermal energy exchange.

The course of work of the present utility model is: when opening water flow switch, the primary coil energising produces magnetic field, responds to short circuit current as the copper pipe of secondary coil because of generation and heats up; Current enter from water inlet 8-1, behind the preheating cooling tube and cooling tube of flowing through all successively, enter copper pipe 8 again and heat, and flow out from delivery port 8-2 at last, finish whole heat cycles.

Adopt the secondary coil winding (short circuit heating tube) of short circuit, should be as far as possible be that the center is evenly distributed by the center of circle of iron core, and should be close to the elementary winding after insulation is handled as far as possible.Secondary windings adopts the low resistance conductor material, as red copper matter etc.Can use welding procedures such as soldering, fine weldering, argon arc welding, also can adopt other technology to make its short circuit.

During the primary coil coiling, its line footpath should be decided according to the designing requirement checking computations of product with the number of turn, and can carry out the multichannel tap as requested, so that the control of power and selection.

No matter secondary coil (short circuit heating tube) adopts low resistance hollow conductor material, and as red copper matter hollow pipe, processing technology and pipeline shape are varied, but which kind of technology of employing and shape, allly can make all can of secondary coil turn-to-turn short circuit.Its operation principle is close with transformer in a word, and difference is secondary.The utility model is to utilize the efficient heat energy that is produced after the high efficiency of O sections core and the secondary short circuited.
