Detailed Description

As shown in fig. 1-4, a novel kettle body 1 produced by a die-casting process comprises a kettle body 11 and a kettle bottom 12, specifically, the kettle bottom 12 is formed by compounding an aluminum layer 121 and a stainless steel layer 122, the kettle body 11 is made of die-cast aluminum which is integrally formed, a limit groove 123 surrounding a circle is arranged on the side wall of the kettle bottom 12, and the lower part of the kettle body 11 is provided with an inner annular edge 111 extending inwards and filling the limit groove 123. In order to maintain the flatness of the kettle bottom 12, a first step 112 is formed above the annular inner edge 111, and the upper edge of the first step 112 is flush with the top surface of the kettle bottom 12. In order to improve the connection strength, the limiting groove 123 is in a dovetail groove shape with a mouth portion narrower than the inside. Further, the thickness ratio of the aluminum layer 121 to the stainless steel layer 122 is 3 or more, and the underlying stainless steel layer 122 is preferably 403 material, which is used for contacting with an electric device such as an induction cooker to realize heat transfer; in order to avoid the direct contact of the kettle body 11, a second step 113 is formed below the annular inner edge 111, and the lower edge of the second step 113 is higher than the bottom surface of the kettle bottom 12.
