Abstract
An induction cooker coil panel comprises a coil panel. An involute winding slot is arranged at the top of the coil panel; enameled copper wires are wound on the involute winding slot; the density between the left and the right or the top and the bottom of the winding slot on the coil panel is changed in an involute manner; the density between the left and the right of the winding slot of the coil panel varies from large to small and then large again in arrangement from the middle of the coil panel to two sides of the coil panel; the enameled copper wires are wound in the winding slot; the height between the top and the bottom of the winding slot in wavy arrangement of the coil panel varies from high to low and then high again from the middle of the coil panel to the two sides of the coil panel; and the enameled copper wires are wound in the winding slot. By adjusting the bilateral clearance or the vertical height of the winding slot on the coil panel, magnetic field generated on the coil panel by the enameled copper wires varies from strong to weak in distribution from the center of a cooker to the periphery of the cooker, the bottom of a heated stove is even in heating, and the induction cooker is more suitable for frying food.
Description
Technical field
The utility model relates to a kind of electromagnetic oven line, specifically is a kind of coil disc of electric stove.
Background technology
Electromagnetic oven is a kind of kitchen range by the electromagnetic field heat food.It produces alternating magnetic field by alternating current by coil, and the irony pan on the boiler face is sensed magnetic field, thereby produces eddy current, again by 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 thereon, 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, so the temperature in pan centre is much higher than the temperature of pan periphery.Because the pan inequality of being heated, so electromagnetic oven generally is not suitable for use in frying in shallow oil cooked food, and the scope of application of electromagnetic oven is restricted.Chinese patent literature CN2634784 discloses a kind of electromagnetic oven heating spool rest on August 18th, 2004, constitute by heater wire one circle circle coiling, it is characterized in that, leave the space between the mid diameter partial line of heating spool rest and the line, it is close that the coiling of whole drum is distributed as two, middle dredging; The gap of described mid diameter paucicostellae partial line and line is 1mm～3mm.Described heating spool rest can be the planar line dish, also can be the cambered surface drum.It is said, it is by expressing the uniformity of controlling magnetic field intensity with the density of the coiling of drum, make the magnetic field intensity of whole drum more even in the different-diameter position, but the coil density degree of this structure is not complete gradual change type, cause coil winding to get and justify (particularly coil is than the part of rarefaction branch) inadequately, thereby can influence the uniformity that it produces magnetic field.Therefore, need further to be improved.
The utility model content
The purpose of this utility model aims to provide the coil disc of electric stove that a kind of simplicity of design is reasonable, bottom, heated pot ground is heated evenly, to overcome weak point of the prior art.
A kind of coil disc of electric stove by this purpose design comprises coil panel, and the coil panel top is provided with the winding slot of involute, and enamel covered wire is around thereon, and its architectural feature is that winding slot density or the height change between the upper and lower between left and right on the coil panel is gradual change type.
The winding slot of described coil panel density between left and right, to both sides, it is close that the arrangement of winding slot becomes from spare to dense again from the centre of coil panel, and enamel covered wire is in winding slot.
The winding slot of described coil panel height between the upper and lower, to both sides, the arrangement of winding slot is wave, uprises from high to low again from the centre of coil panel, and enamel covered wire is in winding slot.
The bottom of described coil panel also is provided with radial magnetic stripe.
By adopting technique scheme, left and right sides gap or the up and down height of the utility model by adjusting winding slot on the coil panel, 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.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 3, this coil disc of electric stove comprises coil panel 1, and coil panel 1 top is provided with the winding slot of involute, and enamel covered wire 2 is around thereon, and the winding slot variable density between left and right on its coil panel 1 is a gradual change type.The winding slot of coil panel 1 variable density between left and right is specially: to both sides, it is close that the arrangement of winding slot becomes from spare to dense again from the centre of coil panel 1, and enamel covered wire 2 is in winding slot.This coil panel 1 is by adjusting the distance between left and right of enamel covered wire 2, makes magnetic field that enamel covered wire produces on coil panel be distributions that grow from weak to strong from the central authorities of cooking stove to its periphery, make bottom the pan be heated more even.The bottom of above coil panel 1 also is provided with radial magnetic stripe.
Second embodiment
Referring to Fig. 4-Fig. 6, this coil disc of electric stove, the winding slot height change between the upper and lower on its coil panel 1 is a gradual change type.The winding slot of coil panel 1 height change between the upper and lower is specially: to both sides, the arrangement of winding slot is wave, uprises from high to low again from the centre of coil panel 1, and enamel covered wire 2 is in winding slot.This coil panel 1 is by adjusting the distance of enamel covered wire 2 and pan bottom surface, makes magnetic field that enamel covered wire produces on coil panel be distributions that grow from weak to strong from the central authorities of cooking stove to its periphery, make bottom the pan be heated more even.Other do not state part, with first embodiment.
