Abstract: A cooking appliance includes a metal body defining a cooking cavity and including a bottom wall that extends from an interior surface defining an upward-facing depression to an exterior surface opposite the interior surface. The bottom wall of the metal body has a first thermal expansion coefficient and a first elastic modulus. A first deformation restriction patch extends along the interior surface of the bottom wall within the upward-facing depression and has a second thermal expansion coefficient and a second elastic modulus. A second deformation restriction patch extends along the exterior surface of the bottom wall opposite the first deformation restriction patch and has a third thermal expansion coefficient and a third elastic modulus.
