The technical schemes are that the heating system of the electromagnetic water heater comprises a circular-ring cylindrical iron core, a primary coil coiled around the edge of the iron core circular-ring column, a cooling water tube coiled along the outer peripheral surface of the primary coil and a copper tube which is served as the hypo-primary coil and is coiled around the edge of the iron core circular-ring column; two ends of the copper tube are respectively connected with the cooling water tube and a water-discharging tube, a welding spot which can form short circuit is arranged between adjacent two circles of copper tubes, and the primary coil is communicated with an electric source by a relay; the copper tubes are evenly distributed and coiled on the edge of the complete-circle iron core circular-ring column in parallel, and each circle of copper tube wraps the iron core, the primary coil and the cooling water tube together; an insulating barrier is made on the iron core and the primary coil respectively.

Description

Magnetic water heater

Technical field

The utility model relates to a kind of fast heating type electromagnet water heater, is particularly suitable for family and uses, and also can be used for the service location that hotel, bathroom etc. need instant hot-water supply.

Background technology

Chinese patent application file (application number 03230182.0) discloses a kind of magnetic media immediately heating water heater, and critical piece is cored, primary coil and secondary coil etc.Iron core is that the silicon sheet by band shape rolls the annulus post that forms, and primary coil is wrapped on the ring limit body of annulus post; Secondary coil is a copper pipe, also is wrapped on the ring limit body of annulus post; The two ends of copper pipe connect cooling water pipe and outlet pipe respectively, and have the solder joint that can form short circuit between the two adjacent rings copper pipe.This water heater has advantages such as little power consumption, reliable operation, service life.Yet its design still has following shortcoming: one, its primary coil is not the whole circle ring cylinder that is covered with iron core, and only twines back and forth on the ring cylinders of about 2/3rds circles, on the ring cylinder that encloses of its excess-three branchs as the winding of secondary coil.Because the primary coil winding position is limited, can only increase the winding number of plies (thickness increase) of coil.So will bring following shortcoming: 1, the number of plies is many more, and is far away more from iron core, and magnetic induction intensity is just poor more, and power factor reduces.2, the coil number of plies increases, and the enamel-covered wire consumption increases, and consumptive material just increases.Two, secondary coil concentrates on 1/3rd positions, be in weak district, magnetic field, can not actual induction and direct balance to magnetic field that primary coil produced, can only in the Movement in Magnetic Field process, absorb its power of 1/3rd and change, can not reach the output (power factor is about 33%) of full power.

The utility model content

Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of improvement of magnetic water heater is provided, and it should have simple in structure, and is safe and reliable, efficient is high, the characteristics of long service life.

The technical solution adopted in the utility model is: magnetic water heater, its heating system 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, have the solder joint that can form short circuit between the two adjacent rings copper pipe, primary coil is by relay and power connection, said copper pipe evenly distributes and is wound on the whole circle iron core annulus post limit, and every circle copper pipe is all with said iron core annulus post limit, the primary coil of coiling and along the cooling water pipe of primary coil outer circumference surface coiling inclusion in the lump on the iron core.

Be shaped on insulating barrier between said iron core and the primary coil.

Be shaped on insulating barrier between said primary coil and the copper pipe.

Because primary coil of the present utility model is wound on the annulated column limit of whole circle annulus post, the coiling position has increased by 1/3rd, the corresponding winding number of plies (twining thickness reduces) that reduced.Not only make core material obtain the most effective utilization, eliminated weak district, magnetic field phenomenon, the magnetic induction intensity that is produced obviously improves, and has reduced material consumption.Again because secondary coil is evenly distributed on whole the circle on the annulus post, be wound on iron core, primary coil and cooling water pipe outside, but the magnetic field that actual induction and balance primary coil are produced, can absorb whole power in the Movement in Magnetic Field process changes, reach the output of full power, efficient significantly improves, and the energy is fully utilized.Because reasonable in design, structure becomes simply, more safe and reliable, prolonged service life.

Fig. 3 is the A-A generalized section among Fig. 1.

The specific embodiment

By Fig. 3, Fig. 2 as can be known: iron core 7 rolls into the annulus column by the silicon sheet of band shape, and iron core is outside to coat the annulus post limit coiling of primary coil 2 wound core on this insulating barrier then with insulating barrier 8 earlier.The enamel-covered wire that constitutes coil is basic parallel with the axis of iron core in the arrangement of the inner circumferential surface of iron core and external peripheral surface, then is arranged in by the center of circle to all around radial at the enamel-covered wire of two radial end faces of iron core.Coat with insulating barrier 6 once more in the primary coil outside.Cooling water pipe 3 is along the external peripheral surface coiling of primary coil after a few, and is also coated in insulating barrier 6.The two ends of this water pipe are respectively water inlet 4 and delivery port 5.The main effect of cooling water pipe is to absorb the heat that primary coil and iron core produced, and prevents their overheated burning out.Water process preheating in the water pipe simultaneously offers the copper pipe as secondary coil, can improve energy utilization efficiency.In addition, primary coil also is provided with some taps 1.These taps can be carried out routine with some relays and switch and be connected, and make water heater can produce the hot water of different class such as high temperature, middle temperature, low temperature, select for use for people.

As seen from Figure 1, Figure 2: the copper pipe 9 wound core annulus post limits as secondary coil, be wound on the insulating barrier 6, generally should on the iron core annulus post limit of whole circle, evenly distribute.The entrance point 12 of copper pipe and delivery port 5 sockets of cooling water pipe, seam crossing 11 usefulness welding manners seal.Water in the cooling water pipe enters the copper pipe heating through preheating, can obtain needed hot water.Water flow switch preferably can be installed by water inlet 6 places of cooling water pipe, when guaranteeing cooling water pipe underfill water, can cut off the power supply of water heater automatically.In addition, all have the solder joint 10 that can form short circuit between the two adjacent rings copper pipe.

In addition, the circuit that the utility model disposed still can adopt application number be 03230182.0 in the circuit shown in please file.

Use the utility model, open water inlet earlier cooling water pipe and extraneous running water are connected, turn on the power switch the connection power supply then, by the short-circuiting effect of electromagnetic induction and adjacent copper pipe, can produce the water in a large amount of heat heating copper tube immediately, the port of export can be exported hot water.
