Abstract
The present invention relates to a pot with a multi-layered bottom and a manufacturing process thereof. More specifically, the pot with a multi-layered bottom made of a stack of different materials is characterized by: an upper aluminum plate being fixed to the base bottom in contact with each other; a perforated plate being fixed to the lower side of the upper aluminum plate and having a plurality of hollow portions; a lower aluminum plate being fixed to the lower side of the perforated plate; a stainless steel plate being fixed to the lower side of the lower aluminum plate and being magnetic; and the corresponding portions of the upper and lower aluminum plates are inserted into the hollow portions of the perforated plate by pressure and thus are interconnected in the hollow portions. In accordance with the present invention, by the multi-layered bottom, heat conductivity and heat efficiency are increased to cook foods in a short time, foods are not scorched and stuck, and the connection force between plates deposited on the lower sides of the base bottom becomes stronger, thereby improving the reliability of the product.
