Description

COOKING PAN AND MANUFACTURING METHOD OF IT

The present invention relates to a pan for cooking food and a method for manufacturing the same. It is about.

Pans such as pots, pots, and frying pans are heated by a heat source to cook food, and are made of aluminum, aluminum alloy and coated aluminum having excellent heat transfer ability.

Of course, the aluminum material, which is a raw material for manufacturing a fan, can be manufactured at a low price, and is harmless to the human body, light and durable, and easy to be molded into any shape and shape, and thus excellent in workability.

However, conventionally, when a cooking pan that does not adhere to a magnet is used to ignite a gas stove, the ignition itself is prevented, and when a cooking pan that does not adhere to a magnet is not heated, the stability is increased during cooking. It was.

Therefore, in the related art, a built-in bottom plate formed of stainless steel or the like attached to a magnet is installed at a bottom portion of an aluminum pan. As shown in FIG. 6, a built-in bottom plate 101 having a plurality of inclined holes 101a is provided. Is fixed to the bottom of the fan body 102, when casting the fan body 102 into a mold (not shown), after inserting the inner base plate 101 into the mold, the flowable aluminum is injected into the mold, at this time fluidity The fan 100 having a shape in which aluminum is filled in the inclined hole 101a of the built-in bottom plate 101 to form the protrusion 102a of the fan body 102 and the built-in bottom plate 101 is built in the bottom of the fan body 102. ) Is manufactured.

Here, conventionally, the bottom center portion of the cooled fan after being separated from the mold is protruded convexly as shown by the chain line of FIG. 6, which has a thermal expansion coefficient of the stainless steel built-in base plate 101 of the aluminum fan body 102. Since the thermal expansion coefficient is smaller than that of the inner base plate and the fan body, the fan body 102 contracts more than the inner base plate 101, so that the bottom center of the cooled fan is convex.
