Description

The frying pan that a kind of electromagnetic oven is suitable for

One, technical field

The utility model relates to a kind of daily cooking utensil, particularly relates to a kind of novel frying pan that is applicable to the flat panel electromagnetic oven.

Two, background technology

Existing kitchen plane heater such as plane electric furnace, plane electromagnetic oven etc. will use pan on request, could guarantee the higher thermal efficiency.Especially the flat panel electromagnetic oven must use pan, could operate as normal.But when pan was used for cooking fried rice, frying pan had tangible inferior position at the bottom of traditional circular arc, mainly was to manipulate inconvenience, the edible wet goods of waste, did not meet the traditional culinary art custom of China.People wish frying pan at the bottom of using circular arc on the electromagnetic oven always, have produced multiple technical scheme at this problem thus.

Double end electromagnetic oven: be the combination of flat panel electromagnetic oven and concave surface panel electromagnetic oven, can use round arc bottom pan, but acquisition cost is too high, the pan versatility is poor, generally promotes than difficulty.

Stainless steel circular arc flat bottom cooker in two multiple ends: existing utility model patent ([21] ZL patent No. 01263888.9) stainless steel circular arc flat bottom cooker in two multiple ends, fail extensively to promote, reason is that the sandwich construction in its bottom of a pan causes heat transference efficiency low, thereby practical value is not very big.

The patent No. is 200420045943.8 the special-purpose pot of utility model electromagnetic oven: be another scheme at this problem, adopt the outer flat the bottom of a pan structure of inner arc, but in this scheme if make the inner surface of frying pan that the radian of enough practicalities be arranged, outer bottom has the radius of enough practicalities, at the bottom of the whole cooker very big weight will be arranged; Secondly, the bottom of a pan peripheral thickness is excessive, with uploading of influence bottom heat.These shortcomings cause this scheme to fail generally to promote.

Plano-concave induction cooker scheme: the plano-concave induction cooker of the positive madam in Taiwan group design, a folding tripod (patent No. is 200420046400.8) has been installed on flat panel, can directly use traditional circular bottom pot.But because the bottom of a pan periphery is bigger with the electromagnetic oven panel distance, be in vacant state, the closed situation in electromagnetic oven magnetic field is relatively poor, and real output descends to some extent, and bigger leakage field is arranged, and easily causes electromagnetic radiation pollution.

The big little pan scheme of portion's arc: at present, some makes pot enterprise for catering to habits of consumers, directly reduce the bottom surface diameter of pan, generally be reduced to 10--12 centimetre, make the lower sidewall evagination of pot simultaneously, and suitably drop to, be equivalent to the bottom of a pan, one fritter plane is set a less arc-shaped pot body bottom of curvature near electromagnetic oven panel, the advantage that had both kept some round bottom frying pans makes the electromagnetic oven substantially can operate as normal again.In this scheme, the arch section in the bottom of a pan is in vacant state, and the working condition of overhanging portion is similar to plano-concave induction cooker scheme, exists effect to reduce and the bigger shortcoming of leakage field.

The plane electromagnetic oven can not use the difficult problem of round arc bottom pan cooking not obtain fine solution always.

Three, utility model content

The purpose of this utility model provides a kind of magnetic conduction good heat conduction effect, the suitable frying pan of little, easy to use, easy to manufacture, the lower-cost electromagnetic oven of leakage field.Wherein the problem that will solve mainly contains three: 1, how will justify arc bottom pan and steadily be positioned on the electromagnetic oven; 2, how to allow pot body respond to alternating magnetic field well, reduce leakage field; 3, how to alleviate the weight of pan as far as possible, reduce radiation loss.

The purpose of this utility model is achieved in that and at first designs suitable pot body curve.Frying pan adopts spherical curve at the bottom of the tradition circular arc, and promptly pot is as a spherical crown, and the pot body curve in the utility model adopts and changes the curvature design, promptly allows the bottom of a pan part comparatively smooth, and curvature is less, and the bottom of a pan increases gradually to sidewall transition region curvature, and curvature reduces again afterwards.Second, the overhanging portion that in neighboring area, the bottom of a pan is the bottom of a pan is provided with irony fin structure or the raised structures that several extend downwards, the shape of these structures can be sheet, lug, nib shape, cylindric, coniform, round table-like, hemispherical (be convenient narration, irony fin structure or raised structures are hereinafter to be referred as fin); The upper end of these fins is base portion or directly is connected as one with a pot body, perhaps links to each other with pot body bottom with the irony plate that is positioned at the bottom of a pan of their integrated setting through one again, and lower ends downward extends to and contacts or near the supporting surface of pan; Bottom at pan is provided with supporter, and its plane, fulcrum place is supporting surface and pot mouthful place plane parallel.The 3rd, fill insulant material or between these fins at their surface attachment insulation materials enamel for example.In as above narrating, two kinds of technical schemes have been comprised.Now be further elaborated with regard to two kinds of technical schemes and principle respectively.

Technical scheme one: the thicker irony frying pan of pot body wall.Directly at several fins that extend downwards of the integrated manufacturing of the bottom of a pan periphery, wherein the part fin extends to same plane as supporter, pan can be supported horizontally inside on the electromagnetic oven panel, and all the other fins extend near electromagnetic oven panel downwards, but do not contact.For alleviating pan weight, in design pot body, during circular curve, make pot curvature of body bottom section less, perhaps, middle part, the bottom of a pan is designed to a planar section than minor diameter, thereby effectively reduces the height of fin.At last fin is cooked insulation and handle, as enamel etc.

When the utility model was positioned on the electromagnetic oven of energising work, the lower end of fin and middle part, the bottom of a pan were in the alternating magnetic field, after the induction heating heat are uploaded to a pot body bottom section; Simultaneously, two adjacent fins become inverted U-shaped flux circuit with part pot figure; Comparatively approaching any two fins become inverted U-shaped flux circuit with part pot figure; Each fin and the bottom of a pan also form flux circuit, will guide the up part pot body that passes of the magnetic line of force, make pot body bottom section and whole fin groups respond to heating simultaneously, thereby are heated up rapidly in whole cooker body bottom.Because most of fin is touch panel not, can prevent to pass under the heat, cause loss; If energy enamel etc., then better effects if.Because the existence of the peripheral fin in the bottom of a pan, effectively closed most magnetic field makes leakage field reduce to reduced levels.

In addition, in order to increase the Energy and comfort of operation, pot of the present utility model is provided with hingle and Ti Er on one's body, the two adopts taper sunk head rivet or sunk screw to be connected with the pot body, manufactured head or head of screw sink to a pot body wall just, become a shiny surface with pot body inner surface, can increase the comfort of the operation that stir-fries, also be convenient to the cleaning of pot.

Technical scheme two: pot body wall is the frying pan of thin irony frying pan, stainless-steel pan body frying pan, aluminum alloy pan body frying pan or other material pot bodies.Set up the irony plate of a tight connecting bottom the pot body in the bottom of a pan, integrated manufacturing is just like the some fins and the supporter of technical scheme one on the plate.For the irony frying pan, pot body, plate, fin can integratedly be made, and setting up an effect that connects plate is the mechanical strength that increases pot, improves the uniformity of the bottom of a pan heat; For stainless-steel pan body frying pan, plate can adopt with the pot body and be welded to connect, to strengthen the magnetic conduction heat-conducting effect; For aluminum alloy pan body frying pan, surface, the bottom of a pan and plate upper surface are provided with the intermeshing dentation of energy, adopt the connected mode that embeds mutually.All the other technical essentials and operation principle and technical scheme one are similar, repeat no more.
