Description

Coil disc of electric stove and pan

Technical field

The present invention relates to a kind of coil disc of electric stove and pan.

Background technology

Electromagnetic oven is a kind of kitchen range that lean on the electromagnetic field heat food.Its alternating current produces alternating magnetic field through coil, and the irony pan on the boiler face is sensed magnetic field, thereby produces eddy current, again through specific control, transforms out a large amount of heat energy on demand and directly makes a pot body generate heat rapidly, reaches the purpose of heat food.Traditional electromagnetic oven since the coil of its coil panel evenly around above that, so the magnetic field intensity of its generation is a uniform field regions of intensity from the center to the periphery.Because the heat radiation of pan centre is significantly less than the pan periphery, thereby the temperature in pan centre is much higher than the peripheral temperature of pan.The inequality because pan is heated, so electromagnetic oven generally is not suitable for as frying in shallow oil cooked food the scope of application of electromagnetic oven being restricted.Chinese patent document number CN201789651U discloses a kind of coil disc of electric stove on April 6th, 2011; Comprise coil panel; The coil panel top is provided with the winding slot of involute; Enamel covered wire is around above that, and density or the height change between the upper and lower between left and right of the winding slot on its coil panel is gradual change type.It is said; This design through the adjustment coil panel on winding slot gap, the left and right sides or up and down the height; Thereby make magnetic field that enamel covered wire produces on coil panel be the distribution that grows from weak to strong to its periphery from the central authorities of cooking stove; The bottom of a pan of heated pot is heated evenly, electromagnetic oven is more suitable for as frying in shallow oil cooked food.But this design complex structure is manufactured the cost height.

Electromagnetic oven is through heater coil disc is set, and utilizes the principle of magnetic field induction to be directly delivered to the pan bottom to heat without boiler face.Induced current is big more, and the heat of generation is just big more.And the magnetic field intensity in the electromagnetic oven of different coil panel structures has nothing in common with each other.For a kind of square coil dish structure, pan on the market is difficult to satisfy the cooperation magnetic field intensity and adapts to the magnetic field induction effect, reaches the whole evenly purpose of heating.Therefore, be necessary to do further improvement.

Summary of the invention

The object of the invention aims to provide a kind of Structure novel reasonable, can realize the coil disc of electric stove and the pan of evenly heating, to overcome weak point of the prior art.

By a kind of coil disc of electric stove of this purpose design, comprise coil panel and coiling coil above that, its architectural feature is that coil panel is the square coil dish of surperficial curved arc shape, coil is square and is coiled on the coil panel.The head of said coil and afterbody are arranged on the coil panel; The center of said coil panel is provided with a through hole.

The medium position H1 of said coil panel leaves the pan bottom farthest, and corner location H2 is nearest from the pan bottom, and its difference of height (H1-H2) is 0.1-40mm; The length of side of said coil panel is d, and d is 200-1000mm.

Be square to the gap gradual change of said coil and be coiled on the coil panel.

The gap of said coil is changed to, and to a semi outer rings, change from small to big in the gap from the center of coil panel; To the outer ring, the gap from large to small from a semi outer rings; The gap length of said coil is all unequal, is 0.1-80mm.

Said coil panel is the square coil dish, and corresponding pan is a square, and coil is foursquare and is coiled on the coil panel, and wherein the A magnetic field, mid court territory of coil panel is the strongest, from the bottom of a pan furthest; Diagonal near zone B magnetic field a little less than, nearest from the bottom of a pan;

Perhaps, said coil panel is the rectangular coil dish, and corresponding pan is a rectangle, and what coil was rectangle is coiled on the coil panel, and wherein the C magnetic field, mid court territory on two of coil panel long limits is the strongest, from the bottom of a pan furthest; Diagonal near zone D magnetic field a little less than, nearest from the bottom of a pan; The E magnetic field, mid court territory of minor face is placed in the middle, and distance is placed in the middle from the bottom of a pan.

A kind of electromagnetic oven pan comprises the pot body and the bottom of a pan that the metal material that is complementary with the said coil disc of electric stove of claim 1 is processed, and its architectural feature is that a pot body surrounds a quadra, and the thickness in the bottom of a pan is not of uniform size to be caused.Said pot body surrounds square or rectangular.

The thickness in the said the bottom of a pan matches with the magnetic field intensity of coil disc of electric stove, and wherein the bottom of a pan midline position thickness h 1 is bigger, and corner location thickness h 2 is less, and its thickness difference (h1-h2) is 0.1-20mm.

The said pot body and the bottom of a pan are that punching press, stretching or die casting are one-body molded, or through being welded to connect.

The present invention is through being equipped with a kind of coil disc of electric stove and pan, and to increase the scope of application of electromagnetic oven, the magnetic field of balance pan bottom guarantees being heated evenly of pan, improves the heat efficiency of electromagnetic oven.
