Abstract

The utility model relates to a ceram kitchen utensil which comprises a lateral wall and a bottom. The utility model is mainly characterized in that a bonding layer is arranged at the bottom of the kitchen utensil, and metal powder is clamped in the bonding layer; the bonding layer can be made from ceramic glaze or enamel glaze and can be arranged on the upper surface or the lower surface of the bottom of the kitchen utensil. The ceram kitchen utensil can be put on an electromagnetic oven to be heated, and the metal powder can not be oxygenized after heated. Because of weak shearing force produced by heat expansion and cold contraction, the bottom of the ceram and a magnetism conducting layer are not easy to disengage.

Description

Ceramic cooker

Technical field

The utility model belongs to a kind of cooker, is specifically related to a kind of ceramic cooker.

Background technology

The traditional ceramics cooker is favored by the consumer deeply owing to advantages such as it are acidproof, alkaline-resisting, nontoxic, show vigorous vitality in market always.But the traditional ceramics cooker can not be placed directly on the electromagnetic oven and heat.For addressing this problem, people have invented a kind of pottery pot, and this pot increased the whole bottom for irony of one deck as magnetic layer in plane pottery bottom, and fill up glaze make above-mentioned two-layer bonding between ceramic layer bottom and irony layer bottom.But still there is following shortcoming in above-mentioned pottery pot: 1, because the pottery bottom is different with whole bottom thermal coefficient of expansion for irony, after the bottom of a pan is heated or cools off, monoblock iron plate is because the stress that distortion produces can be concentrated the accumulation stack, and concentrate on certain local shear stress that produces between two-layer, thereby through repeatedly using both disengagings gradually easily of pottery bottom, back and irony bottom.2, the irony bottom is directly exposed in the air, the back oxidation easily, rotten of being heated.3, only be adapted to the bottom and be the pot on plane, be the pot of curved surface and can not be adapted to the bottom.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of ceramic cooker is provided, and it can be placed directly in heats on the electromagnetic oven, and its magnetic layer and the ceramic the bottom of a pan are not easy again to break away from, and are the pot of curved surface bottom being adapted to.

For realizing above purpose, ceramic cooker of the present utility model comprises sidewall and bottom, and its main feature is, is provided with a tack coat in the cooker bottom, has been embedded metal powder in this tack coat.

Described tack coat can be ceramic glaze.

Described tack coat also can be frit for porcelain enamel.

Described tack coat can be arranged on the cooker upper base surface.

Described tack coat also can be arranged on cooker bottom lower surface.

The utlity model has following advantage and effect:

1, this ceramic cooker can be placed on above the electromagnetic oven and heat.When the electromagnetic wave of electromagnetic oven passes through metal powder, can produce electromagnetic eddy and heating.

2, more or less there are certain interval each other in each metal powder grain or powder; so behind each metal powder expanded by heating; they since the stress that distortion produces most of can its separately around near obtain discharging; to not be out of shape the stress that produces the monoblock iron plate and all stack up and can not resemble; thereby after the bottom of a pan is heated or cools off; because the shearing force of the generation of expanding with heat and contract with cold is little, both are not easy to break away between pottery bottom and the magnetic layer.

3, metal powder is embedded in the enamel tack coat, and major part is not directly exposed in the air, can oxidation after the heating.

4, can be adapted to the cooker of bottom for curved surface or plane.

If 5 are arranged on the upper surface of cooker bottom with tack coat, food was directly contacted with magnetic layer increased heat conduction efficiency, avoid magnetic layer directly to contact with air, reduce heat radiation, again because metal powder is embedded in the enamel tack coat, needn't worry that metal powder is corroded or dissolves in the food on the other hand.

6, because the thickness of magnetic layer and cooker produce the efficient of heat direct relation is arranged, regulate the thickness of magnetic layer when ceramic cooker of the present utility model is produced easily, and do not exist the magnetic layer thickness of other ceramic cookers when producing, to be subjected to the problem of semi-finished product iron plate thickness limits.The magnetic layer thickness of ceramic cooker of the present utility model both can have been done very thinly, also can do thicklyer.
