Abstract

A magnetic media instant heating water heater relates to an instant heating electromagnetic induction water heater, being particularly applicable to hotels, bathrooms, families and places needing hot-water supply instantly, comprising an iron core arranged in the shell, a primary winding and a secondary winding, characterized in that the iron core is a ring column wrapped by a zonal sillical sheet, with the outer surface of the iron core being covered with an insulating layer. The primary winding is a main solenoid with an insulating cover, which is enlaced on the ring body by a wire, and the head end out going line and the terminal end out going line are connected with power source through a relay. The secondary winding is a set of ring shaped copper pipes enlaced on the iron core, with both ends of the copper pipes being respectively connected with a cooling pipe and a water outlet pipe through a connecting pipe, and solder joints which can form short circuit are arranged between two adjacent cooper pipes, thereby resolving problems of the prior electromagnetic induction water heater of power wasting by low magnetic permittivity, high cost by needing plenty of raw material, being unreliable with easily burn out by excessive heating and the like, and achieving the advantages of being able to adjust the hot-water temperature, and convenient and safe to use.

Description

The magnetic media immediately heating water heater

Technical field

The utility model relates to a kind of Instant heating type electric heater, particularly induction water heater.It can be used for the place that restaurant, bathroom, family etc. need confess hot water immediately especially.

Background technology

Chinese patent 98216667.2 disclosed " magnetic induction type electric heater ", it contains housing, iron core, primary coil and secondary coil, wherein secondary coil is the metal tube and ring of one group of its entrance point and port of export short circuit welding, and the insulation tube that has the connection current to use between each metal tube and ring respectively.Though its energy is convenient and reliable and confess hot water immediately, also has following shortcoming: the 1) coil that twines on left and right iron prop, cause leakage field because of lower yoke member on it is exposed to, so coil is not fully utilized in the air; 2) number of plies with coil increases, and its outer coil is because of weakening away from the iron circuit magnetic conductance; Occur burr or out-of-flatness when 3) the silicon sheet of composition iron core is because of cutting inevitably, its result also causes magnetic conductivity to descend; 4) cooling water in this water heater can't carry out heat exchange to the heat that coil and iron core produced, and therefore, for preventing to damage because of overheated, its each time of using is unsuitable oversize.In a word, the thermal efficiency of this water heater is high not enough, relatively take electricity, makes also more bothersome, and unsuitable long-time continuous use.Chinese patent 02111329.7 disclosed " a kind of electromagnetic induction type water heater ", its shortcoming is: the 1) space of leaving between its soft magnetism core body and the heating layer and the power of main coil is multiplied, thus take very much electricity, even up to 10-20 kilowatt; 2) cooling water is to be heated intensification by the space that from top to down is flowed through between soft magnetism core body and the heating layer, is full of water but be somebody's turn to do in the range request space, otherwise water heater can because of overheatedly burn out, hot water ended, so its work is unreliable; 3) it causes a large amount of leakage fields because of primary coil from iron core is distant, so power attenuation also more greatly, relatively take.

Summary of the invention

The utility model is to overcome the shortcoming that exists in the above-mentioned prior art, provide a kind of security good, can confess the magnetic media immediately heating water heater of hot water and power saving immediately reliably, and make it have simple and reasonable, the temperature of adjustable hot water, easy to use and characteristics such as the compact conformation volume is little, long service life.

The utility model magnetic media immediately heating water heater, it contains iron core, primary coil and the secondary coil that is installed in the housing, and be characterized in: its iron core is that a silicon sheet by band shape rolls the annulus post that forms, and is surrounded by insulating barrier on its outer surface; Primary coil is the main line bag of a tape insulation layer on the torus that is wrapped in iron core with lead, and its head end lead-out wire is connected power supply with terminal lead-out wire by relay; Secondary coil is one group of copper pipe that is round that is wrapped on the iron core, and the two ends of copper pipe connect cooling water pipe and outlet pipe by a tube connector respectively, and have the solder joint that can form short circuit between the two adjacent rings copper pipe.

The utility model magnetic media immediately heating water heater is preferably with water flow switch on its outlet pipe.To guarantee when the cooling water pipe underfill water, can cut off the power supply of water heater automatically.

The utility model magnetic media immediately heating water heater, its cooling water pipe is along the circumferential winding of primary coil and secondary coil and the round pipe that is arranged in order along its short transverse, and the one end by tube connector be connected with the copper pipe of secondary coil, end is connected with the running water pipe in the external world in addition.So that cooling water is in time taken away the work of heat on primary coil and the iron core, water heater is more reliable.

The utility model magnetic media immediately heating water heater also has the lead-out wire that is connected with relay on its primary coil loop therebetween, and has temperature detect switch (TDS) on its secondary coil place circuit.

The beneficial effects of the utility model are: 1) because of iron core is that bar shaped silicon sheet with band shape is entwined on up-coiler, both avoided because of shearing the disadvantage that magnetic conductivity that the silicon sheet brings descends, convenient again make and volume little; 2) iron core of annulus cylindricality makes coil can all cover its surface, so the utilization rate of iron core improves greatly, coil also reduces number of turn level because of being fully utilized, make the raw material save about 1/3, and overcome big and the phenomenon that loss increases of impedance, consequently little, the cost of voltage drop reduces; Handle if the iron core that opposing connection makes carries out backheat, so that its molecular structure reconfigures arrangement, then its magnetic flux can increase 2-3 doubly, thereby power consumption is descended greatly; 3) the utility model effectively prevents water heater because of the overheated danger that burns out, thereby guarantees its reliable operation, long service life by arranging the big calorimetric that comes balance primary coil and iron core to be produced around the cooling water pipe of coil periphery; 4) the utility model is also pulled out one group of lead-out wire that can be connected with relay by tap on the mesosphere circle of primary coil, and the realization people can change its hot water of confessing at any time and work as temperature adjustment, especially gives people with safety and convenient when being used for the bathroom.
