Description

Electromagnet water heater

Affiliated technical field

The utility model relates to a kind of electric heater, specifically a kind of with electric energy by---magnetic, magnetic---electricity conversion induces eddy current in iron core, make the sharply rising and add the electromagnet water heater of hot water of iron core temperature.

Background technology

At present public electric heater is that resistance wire or resistive element outer surface are covered very thick insulating barrier in order to the heater that adds hot water, puts the metal sleeve sealing again and make outside insulating barrier.Its shortcoming is: transmission has very big inhibition to heat for one, the insulating barrier between resistance wire or resistive element and the metal sleeve, and the heat that resistance wire or resistive element are produced is difficult for being passed to water.Its two, heater is whole water-immersed, requires metal tube sealing reliable, in case poor sealing, water infiltrates insulation is made moist, insulation effect will be lost the generation that the beginning causes electric shock accidents to the greatest extent.Its three since the insulation effect of heater and sealing reliability are required very high, so structure and production technology more complicated all.

Present another public electromagnetic oven, its advantage is: one, water, electricity are isolated fully, it is to produce vortex flow by electromagnetic induction on the iron pan body, make iron pan body self-heating and the interior water of heating kettle, across insulation boards such as thick devitrified glass, potteries, be in the state that separates fully between iron pan and the heater coil that has dangerous voltage between its calandria one iron pan and the heater coil.Its two, thermal efficiency height, the calandria iron pan directly contacts with water, the intermediate material of empty calory conduction.Its shortcoming is: can only make cooking usefulness, not have the function of water heater continuous heat supply water.

Summary of the invention

Be subjected to the obstruction of insulating barrier for the heater that overcomes existing electric heater, heat is difficult for being passed to water, and require the metal sleeve sealing reliable, otherwise easily produce all shortcomings of more complicated of Danger Electric shock risk and structure and production technology, though and electromagnetic oven has the intermediate material of empty calory conduction, be in the state that separates fully between the thermal efficiency height, calandria and the heater coil that has dangerous voltage, but it can only be done cooking and use, and does not have the function of continuous heat supply water.This electromagnet water heater that is suitable for novel proposition can make water, electricity separate fully, the heater direct contact water, and the thermal efficiency is high and simple in structure.

The utility model solves the technical scheme that its technical problem adopted: have shell 1, nontoxic heatproof plastics inner bag 3 inner bottom parts that the centre accompanies heat-insulation layer 2 are equipped with one to two iron or corrosion resistant plate 4 with magnetic conduction electric conductivity, install one in the outside of plastics inner bag 3 bottoms over against the position of every magnetic conduction conductive plate 4 and be twisted into one with the concentric garden mode inductance coil 5 of coiled plate-like from inside to outside by the multiply enamel-covered wire, below plate-like inductance coil 5, evenly be close to many magnetic stripes 6 are housed, high frequency alternating current generator that is electrically connected with plate-like inductance coil 5 and control circuit 9 are loaded in the complete inaccessiable closed container 10 of humid air, the IGBT pipe 11 and the rectification full-bridge 12 that are electrically connected with high frequency alternating current generator and control circuit 9 are loaded in the cooler 13, cooling water pipe 14 also is housed in the cooler 13, fill with insulating oil in the cooler 13, IGBT pipe 11 and rectification full-bridge 12 are immersed in the insulating oil, when starting high frequency alternating current generator and control circuit 9 in plate-like inductance coil 5 during logical people's high frequency alternating current, plate-like inductance coil 5 produces high-frequency alternating magnetic field, this high-frequency alternating magnetic field passes plastics inner bag 3 bottoms and acts on magnetic conduction conductive plate 4, in magnetic conduction conductive plate 4, produce powerful eddy current, magnetic conduction conductive plate 4 is generated heat rapidly, water in the heating of plastic inner bag 3, running water at first enters from water inlet pipe 7, behind cooling water pipe 14, enter plastics inner bag 3 bottoms, wash from the outlet pipe 8 outflow confessions on plastics inner bag 3 tops through the water of magnetic conduction conductive plate 4 heating, bathe to wait and use hot water.The physical form of nontoxic heatproof plastics inner bag 3 is made the arbitrary shape that can tolerate tap water pressure, when nontoxic heatproof plastics inner bag 3 bottoms are camber, magnetic conduction conductive plate 4 and plate-like inductance coil 5 are also wanted the corresponding camber of making, what high frequency alternating current generator and control circuit 9 can be looked water heater requires the suitable circuit of flexible design, also can directly use commercially available electromagnetic oven maintenance panel replacement high frequency alternating current generator and the high frequency alternating current generator in the control circuit 9 when doing exploitation, reduce degree of difficulty when making the entrepreneur develop this product greatly.

The beneficial effects of the utility model are: one, heater separates fully and isolates with the element assembly of band dangerous voltage, has accomplished that water power thoroughly separates.Its two, heater directly contacts with water, empty calory conduction loss, thermal efficiency height.Its three, the electromagnetic field of high frequency is except that acting on heater, also partial action is difficult for scaling in water.Its four, it is low that nontoxic heatproof plastics are made the inner bag cost, it is more reliable to insulate.
