Description

Electromagnetic oven induction coil spacing device

The utility model relates to a kind of electromagnetic oven induction coil spacing device, refers to that especially induction coil can keep the spacing device of certain induction spacing with the ceramic panel of its top and pan at each position.

Press, electromagnetic oven mainly utilizes the electromagnetically induced effect, electric current is entered with copper cash twine the coil that iron plate forms, and produces magnetic force induction, generates heat by the pan generation eddy current that is placed on the boiler face again.Because it is that the heat that the mat pan is produced takes processed food, therefore the boiler face made from pottery can not generate heat, and has the advantage of the no oil smoke of cleaning simultaneously when cooked food.

As shown in Figure 1, be general working principle of induction cooker, it can place pan 11 in the surface of the ceramic panel 10 of electromagnetic oven, below panel 10, then be provided with copper cash and twine the coil 12 that iron plate forms, this coil 12 is at the magnetic line of force 13 by electric current produced, make that pan 11 is inner to produce eddy current 14, but pan 11 thereby heating and cooked food.Can find out that according to above-mentioned electromagnetic oven operation principle electromagnetic oven must use the metal pan with preferable resistance coefficient, as iron pan or stainless-steel pan.If use nonmetal pan, during as glass boiler, promptly must be in 15 coatings (Coating) of the bottom surface of pot with the magnetic conduction coating.

In existing electromagnetic oven, be ceramic panel and the pan uniform induction heating that makes coil and its top, all be made as tabular at as shown in Figure 1 coil 12 and panel 10, therefore also must use and contain flat pan 11, make this plane, the bottom of a pan 15 can with ceramic panel 10 smooth laying.But in existing cooking food mode, be that the pan (as frying pan) of cambered surface is cooked to fry and is quite common mode with the bottom of a pan, but be subjected to restriction, and can't on electromagnetic oven, use frying pan as above-mentioned electromagnetic oven structure commonly used.

The purpose of this utility model is to overcome existing electromagnetic oven structure and is unsuitable for the restriction of arc bottom pan tool, and then a kind of electromagnetic oven induction coil spacing device is provided, to enlarge the range of application of electromagnetic oven.

The purpose of this utility model is achieved in that

A kind of electromagnetic oven induction coil spacing device, comprise coil, tray, contour pad, column and spring etc., it is characterized in that being provided with an arc coil that contains centre bore in electromagnetic oven inside, this coil combination is in a tray surface, this tray is provided with the periphery frame greater than coil diameter, but and the prominent ring in the center in the default above-mentioned hub of a spool of fit hole, form between the prominent ring in this center and the periphery frame and bear locating surface and supply to insert coil; On this external all frame and be provided with a plurality of lugs, lug and column fit together, and are provided with the compression spring between column and the lug, for hold-in winding with its above the induction spacing of ceramic panel and pan.

The purpose of this utility model can also further realize by following technical measures:

Aforesaid electromagnetic oven induction coil spacing device, tray between the prominent ring in periphery frame and center, be provided with a plurality of radially sheets and in ring, and bear locating surface for formation cooperating coil circumferential position place to contain concave part.

Aforesaid electromagnetic oven induction coil spacing device, tray periphery frame lug is preset through hole, then be provided with on the column and can be with the compression spring on the minor axis bolt for packing into, and be fixed together with column after for the bolt of packing into by above-mentioned lug through hole establishing inner bolt hole on the minor axis bolt in the minor axis bolt of this through hole.

Aforesaid electromagnetic oven induction coil spacing device, column is provided with ring portion, makes compression spring upper end compress the lug bottom surface, and the lower end then is pressed against ring portion on this.

Advantage of the present utility model: owing to adopted the coil spacing device of electromagnetic oven, and arc pan (as frying pan) can be applicable on the electromagnetic oven, make the cooking food mode of electromagnetic oven more extensive and handy, have actual utilization benefit.

Below in conjunction with Figure of description and embodiment the utility model is further described:
