Description

Cylinder type electromagnetic heater for container

The utility model is about a kind of electromagnetic heater, is meant a kind of electromagnetic heater of cylindrical vessel especially.

Known to prior art, heat the food in the container of can and so on, normally the food in this can is poured in the vessel, these vessel are placed on the heater heat again by the bottom.This mainly is because the floor space of can is too little, is not suitable for placing on the heater and is directly heated by the bottom surface.Though recently abroad developed a kind of with can bottom during fabrication attaching go into the material that can react heating so that for the usefulness of one-time heating, wherein be enough to for the cost of the material of a can heating too high, so be difficult to popularize.Then only can induction heating have the container of big planar base surface as for the electromagnetic oven that generally uses at present, not good for the efficiency of heating surface of the high drum ladle of can and so on, and inapplicable.

Main purpose of the present utility model is to provide a kind of electromagnetic heater of cylindrical vessel, and can have multinomial heating purposes such as heating the circular flat bottom vessel concurrently, reaches a tractor serves several purposes purpose.

Another purpose of the present utility model is providing a kind of electromagnetic heater of cylindrical vessel, and wherein the package assembly of solenoid coil and iron core has innovation, thereby is convenient to combination.

Another purpose of the present utility model is providing a kind of electromagnetic heater of cylindrical vessel, wherein, when cylindrical vessel heats, has set up a safty shield, hurts sb.'s feelings in case meet accident during the can over-heating.

The utility model is presented as a kind of cylindrical vessel electromagnetic heater, comprising: base, top cover and induction coil,

It is characterized in that the heating of described cylindrical vessel electromagnetism also comprises: recessed cylinder cover portion is positioned at the left side of described base; Tabular shell face is positioned at the right-hand part of described base; Cylinder base is arranged on the described base, and bearing sleeve is around described cylinder cover portion, and this cylinder base root edge is provided with a plurality of location shrinkage pool;

Described induction coil comprises:

The cylinder induction coil is cylindric, around the periphery that is arranged on described cylinder base;

Planar induction coil is tabular, and coiling is arranged on the described tabular shell face;

This electromagnetic heater also comprises a plurality of laminar clamp hook pieces, its inboard respectively comprises rectangular iron core, and sheet is colluded in the top installing, and inlay card is on the location of described cylinder base shrinkage pool and cylinder base shell wall, each iron core is evenly distributed in around the described cylinder induction coil, so that assembly.

About detailed construction of the present utility model, function and characteristics, can get fully by the detailed description of following examples conjunction with figs. and understand.

Fig. 1 is the top view of the cylindrical vessel electromagnetic heater of an embodiment of the present utility model.

Fig. 2 is the front view of the cylindrical vessel electromagnetic heater of Fig. 1, and part section wherein is in order to show internal structure.

Fig. 3 is the 3-3 cutaway view of Fig. 1.

Fig. 4 is the exploded stereogram of solenoid coil cylinder base of the present utility model.

Shown in Fig. 1 to Fig. 4, the utility model cylindrical vessel electromagnetic heater comprises: a base 12 and a top cover 14, be the rectangle housing that injection moulding shapes, wherein the left side of this top cover 14 has a recessed cylinder cover portion 16, and right-hand part is a tabular shell face 18.

One cylinder base 20, it is a cylindrical member, be positioned on this base 12 and be enclosed within just this cylinder cover portion 16 around, its peripheral root edge has four shrinkage pools 21, four clamp hook pieces 22 are thin sheet-like element, its inboard respectively includes a rectangular iron core 23, thereby the bottom is embedded at location in this shrinkage pool 21, and the top is again to collude the top periphery that sheet 24 is hooked in cylinder base 20; Also having an induction coil 25 is to be cylindric this cylinder base 20 peripheries that are surrounded on, promptly between iron core 23 and barrel.

One cover cap 30 is a housing that raises up, and one end both sides respectively have the protruding tip 31 so that be fastened on the precalculated position of top cover 14, and both can turn round relatively, and these cover cap 30 other ends then have a hook part 32; Also has a button 33, be the arc sheet element of injection mo(u)lding, be hubbed on a recess of top cover 14 by protruding axle 34, in order to urge a spring 35 to turning down, so that make its leading edge 36 leave this hook part 32, make this cover cap 30 can raise or be flicked by the elastic force effect of spring.

One planar induction coil 40 is coiled into flat induction coil for a kind of, is installed in the bottom surface of this tabular shell face 18, as the usefulness of pan at the bottom of the heated flat.

This cylindric induction coil 25 and this planar induction coil 40 all can be connected to the output of a higher-order of oscillation drive circuit, by this drive circuit one of this two

induction coil

25,40 is switched on, so that generation alternating magnetic field, thereby pan or cylindrical vessel at the bottom of the heated flat, this drive circuit is a known technology, needn't describe in detail here.

The operating position of above-mentioned this cylindrical vessel electromagnetic heater is described as follows:

In this recessed cylinder cover portion 16 of these top cover 14 left sides, can insert cylindrical vessel or can 50, again cover cap 30 is covered, make its hook part 32 grabs in the leading edge 36 of this button 33, and touch a sensitive switch, like this, just can start electromagnetic heating circuit, make solenoid coil 25 produce alternating magnetic field, make the 50 induction heatings of tinplate can, with food in the heating tank.Its degree of heat can be controlled by temperature switch, cuts off the power supply automatically when for example control is heated to 60 ℃; Also can after heating reaches the scheduled time, cut off the electricity supply automatically,, add the safe covering effect of this cover cap 30, the maltilevel security protection purpose in the time of can reaching the can heating to ensure heating safety.When the can heating finishes, make its leading edge 36 break away from hook part 32 as long as push this button 33, then can flick mode or raise this cover cap 30, so that take out heating can 50, because its heating surface (area) (HS is big, so heating is rapidly by spring with hand.These top cover 14 right-hand parts then can provide known electromagnetism heating function for placing flat pan.

According to above-mentioned explanation as can be known, the utility model cylindrical vessel electromagnetic heater, because cylinder base and iron core easy to assembly is provided, be provided with a cover cap in addition again to increase safety in utilization, and cylindrical vessel and flat pan all can use, having reached the multipurpose purpose, really is a progressive practical utility model design.
