Description
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 by electromagnetic field heat food.Its alternating current produces alternating magnetic field by coil, and the irony pan on boiler face senses magnetic field, thus produces eddy current, then is controlled by specific, transforms out a large amount of heat energy on demand and directly makes a pot body generate heat rapidly, reach the object of heat food.Traditional electromagnetic oven is because the coil of its coil panel is evenly around thereon, and therefore its magnetic field intensity produced is the field regions of an even intensity from the center to the periphery.Because the heat radiation of pan centre is significantly less than pan periphery, thus the temperature in pan centre is much higher than the temperature of pan periphery.Because pan is heated inequality, therefore electromagnetic oven is generally not suitable for use in decocting cooked food, and the scope of application of electromagnetic oven is restricted.Chinese patent literature CN201789651U discloses a kind of coil disc of electric stove on April 6th, 2011, comprise coil panel, coil panel top is provided with the winding slot of involute, enamel covered wire is around thereon, and the density between left and right of the winding slot on its coil panel or height change are between the upper and lower gradual change type.It is said, this design is by adjusting gap, left and right or the upper-lower height of winding slot on coil panel, thus the magnetic field that enamel covered wire is produced on coil panel from the central authorities of cooking stove to its periphery in the distribution that grows from weak to strong, the bottom of a pan of heated pot is heated evenly, electromagnetic oven is more suitable for as decocting cooked food.But this design complex structure, manufactures cost high.
Electromagnetic oven is by arranging heater coil disc, and utilizes the principle of magnetic field induction that heat is directly delivered to bottom pan without boiler face.Induced current is larger, and the heat of generation is larger.And magnetic field intensity in the electromagnetic oven of different coil disk structure is different.For a kind of square coil dish structure, pan is on the market difficult to meet cooperation magnetic field intensity and adapts to magnetic field induction effect, reaches the object of overall homogeneous heating.Therefore, be necessary to be further improved.
Summary of the invention
Object of the present invention aims to provide a kind of novel and reasonable structure, the coil disc of electric stove that can realize homogeneous heating and pan, to overcome weak point of the prior art.
By a kind of coil disc of electric stove that this object designs, comprise coil panel, and coiling coil thereon, the square coil dish of its architectural feature to be coil panel be surperficial curved arc shape, coil is square and is coiled on coil panel.The head of described coil and afterbody are arranged on coil panel; The center of described coil panel is provided with a through hole.
Bottom pan farthest, bottom pan recently, its difference of height (H1-H2) is 0.1-40mm to corner location H2 to the medium position H1 of described coil panel; The length of side of described coil panel is d, d is 200-1000mm.
Be square to the gap gradual change of described coil and be coiled on coil panel.
The gap of described coil is changed to, and from the center of coil panel to a semi outer rings, change from small to big in gap; From a semi outer rings to outer ring, gap from large to small; The gap length of described coil is all unequal, is 0.1-80mm.
Described coil panel is square coil dish, and corresponding pan be square, and coil be foursquarely coiled on coil panel, and wherein the A magnetic field, mid court territory of coil panel the most by force, from the bottom of a pan apart from farthest; Diagonal near zone B magnetic field is the most weak, nearest from the bottom of a pan;
Or described coil panel is rectangular coil dish, corresponding pan is rectangle, and what coil was rectangle is coiled on 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 distance farthest; Diagonal near zone D magnetic field is the most weak, nearest from the bottom of a pan; The E magnetic field, mid court territory of minor face is placed in the middle, placed in the middle from the bottom of a pan distance.
A kind of electromagnetic oven cooker, comprise pot body and the bottom of a pan that the metal material that matches with coil disc of electric stove described in claim 1 makes, 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.Described pot body surrounds square or rectangular.
The thickness in the described 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 comparatively large, and corner location thickness h 2 is less, and its thickness difference (h1-h2) is 0.1-20mm.
Described pot body and the bottom of a pan are that punching press, stretching or die casting are one-body molded, or by being welded to connect.
The present invention is by 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 bottom balance pan, ensures being heated evenly of pan, improves the heat efficiency of electromagnetic oven.
