Description

Automatic electromagnetic stove for water

The utility model relates to a kind of electric water-boiling device tool of electromagnetic induction heating.The electric water-boiling device tool of Xiao Shouing is various in style by classification such as its temperature control pattern, appearance structure, modes of emplacement, capacity in the market, but its electric heating form generally is a resistance heating, and this mode of heating heat efficiency is low, power consumption is big.Current in office, group, especially in vehicle, boats and ships, aircraft and inflammable, explosive place, pressed for a kind of safety, power saving, fast heat, efficient electric water-boiling device tool easily.

Induction heating method extensively applies to metal smelt, punching press, forging, fields such as heat treatment both at home and abroad in heavy industry.In light industry, be used for drying and make fast thermoelectric flatiron etc.The electromagnetic stove electric heating cooking cook ware that appearance is made with inductive heating principle in the seventies household electronic products.The eighties product heat efficiency reaches 80%.

The utility model purpose provides a kind of new model automatic water boiler, and this stove and accessory has automatic boiler structure and heat-insulating property, utilizes the automatic boiled drinking water of electromagnetic induction heating mode.The electromagnetism automatic water boiler, programming rate is fast, heat efficiency height, the flames of anger, pollution-free, no incrustation scale, safe and convenient to use, the magnetization boiling water that can provide continuously has health, body-building function, and has voltage-selected switch, is suitable for multiple power supply form and place.

The utility model is achieved in that be the air core coil with thermal insulation, insulation property by copper core enamelled wire coiled through the inductor (3) of cured, the inner furnace body (1) that is pressed into by middle heat insulation layer (4) and ferromagnetism corrosion resistant plate fits tightly, and inner furnace body (1) outer surface scribbles insulating barrier.Frequency is provided is the electric current of 20～40KHZ to inductor (4) by being installed on movable control cubicle (5) medium-high frequency generator on the furnace body frame (6), make inner furnace body (1) lining that is in the alternating magnetic field produce maelstrom, the Joule heat that eddy current overcomes the material internal resistance generation of inner furnace body (1) own is exactly the thermal source of boiled drinking water.Because heat produces in inner furnace body (1), the bottom heat insulation layer (4) is arranged thus heat not to outdiffusion safety, the heat efficiency up to more than 83%.

Fallible component, set of devices are contained in the drawer type control cubicle (5) on the underframe (6) in the control circuit of the present utility model, when wherein arbitrary element or device break down, can change the intact standby control cubicle of another control performance easily.

Below with reference to accompanying drawing two embodiment of utility model are described in further detail

Fig. 1 is a garden type inner furnace body electromagnetism automatic water boiler schematic diagram.

Fig. 2 is a rectangle inner furnace body electromagnetism automatic water boiler schematic diagram.

Fig. 3 is an electromagnetic drinking water boiler voltage-selected switch schematic diagram.

With reference to Fig. 1, inner furnace body (1) is equipped with one with thick for the ferromagnetism corrosion resistant plate of 1mm is pressed into garden column shape container and the middle body of heater (2) (with (1) material) that diameter is φ 220, scribble the phosphate insulating barrier in inner furnace body (1) and the cavity sidewalls that middle body of heater (2) forms, turn to the inductor (3) of air core coil through the high-temperature ceramic materials curing molding with the copper enamelled wire, the centre is separated with closely connected bottom surface and the side that is fastened on inner furnace body (1) of the heat insulation layer made from the thick adiabatic asbestos board of 1mm (4).Inner furnace body (1) bottom is supported on the underframe (6) with cross-over block (9).When manipulation is installed in voltage-selected switch (8) on the active cabinet (5), radio-frequency generator in the control cubicle (5) provides the high frequency (electric current of 20KHZ～40KHZ) to inductor (3), then the maelstrom that causes in inner furnace body (1) overcomes internal resistance generation heat, the cold water that enters in the container that inner furnace body constitutes via magnetizer (13), cold water storage cistern is heated to be boiling water very soon, and boiling water jumps and goes out inner furnace body (1) top and enter in the boiling water apotheca (14) that external furnace body (11) forms.Cold water constantly replenishes to the container that inner furnace body constitutes through magnetizer (13) simultaneously.When the water level in the boiling water apotheca (14) is raised to upper limit level sensor (12), cut off the electricity supply automatically, stop heating.Middle body of heater (2) has the effect of the leakage field of collection, can produce small amount of thermal too, can make the boiling water insulation in the boiling water apotheca (14).

In case arbitrary control element or device break down, can go up by underframe (6) and take out control cubicle (5), change standby control cubicle (5) easily.Have the louver transom window on control cubicle (5) shell, in impelling

Body of heater (1) is ventilated with the cavity that middle body of heater (2) forms, air-cooled inductor (3).When the water surface in the boiling water apotheca (14) is higher or lower than the lower limit level sensor (10) that is installed on the external furnace body (11), is assemblied in water level display (7) on the control cubicle (5) and will sends and have or not water power light shows signal.

By voltage-selected switch (8), contact pin (15) and (16) are received on contact pin (17) and (18), and the electromagnetism automatic water boiler provides 50 volts of direct voltages with 220 volts of alternating voltages of common civil power and through rectification circuit (21) to boiler operating circuit (22); When closing (8) by voltage-selected switch, contact pin (15) and (16) are received on contact pin (19) and (20), boiler operating circuit (22) can use on the passenger train, axletree power generating type power supply, and its alternating current generator electric supply installation can provide 43 volts to 60 volts direct voltage.

Different with Fig. 1 is, inner furnace body among Fig. 2 (1) is to make flat rectangle, and manufacturing process is simple, but the heat efficiency is poorer slightly.
