Abstract
A cooking vessel suitable for use with induction plates as well as with conventional electric cooking plates, ceramic hobs or gas cookers has an inner wall, an outer wall, and a thermally conductive plate arranged along the bottom of the vessel and between the inner and outer walls. The outer wall is formed of a composite material having an outer layer of a rust-proof material, a middle layer of a ferromagnetic material, and an inner layer of a rust-proof material. The inner wall is connected to the outer wall in a gas-tight manner along the rim of the vessel.
Claims19
A cooking vessel adapted for use on induction plates and for electric or flame cooking, heating and serving, and including a pot having an inner wall and an outer wall, each of which are continuously formed shells connected to one another in spaced relation to one another, a heat-conducting plate connected between bottom portions of the inner wall and the outer wall in a heat-conducting manner, and a double-walled lid;
- wherein the pot and the lid are stepped in their contact zone including a recessed annular surface in the inner wall of the pot and a matching bearing surface of the lid so that the lid is embedded in the pot, and the pot and the lid meet along a widened circumferential rim for ensuring dimensional stability along the rim;
- wherein at least the outer wall of the pot is produced from a composite material having at least one layer formed of a ferromagnetic material;
- and
- wherein the inner wall and the outer wall of the pot are connected to one another in a gas-tight manner at the rim.
A cooking vessel adapted for use on induction plates and for electric or flame cooking, heating and serving, and including a pot having an inner wall and an outer wall, each of which are continuously formed shells connected to one another in spaced relation to one another, a heat-conducting aluminum plate connected between bottom portions of the inner wall and the outer wall in a heat-conducting manner, and a double-walled lid;
- wherein the pot and the lid a re stepped in their contact zone including a recessed annular surface in the inner wall of the pot and a matching bearing surface of the lid so that the lid is embedded in the pot to create a ring-shaped intermediate zone in which water can condense and accumulate, and flow back into the vessel, to at least partially fill the ring-shaped intermediate zone to contribute to insulation between the rim of the lid and the rim of the vessel upon which it is removably seated;
- wherein the pot and the lid meet along a widened circumferential rim for ensuring dimensional stability along the rim;
- wherein at least the outer wall of the pot is produced from a composite material having at least one layer formed of a ferromagnetic material;
- and
- wherein the inner wall and the outer wall of the pot are connected to one another in a gas-tight and dimensionally stable manner at the rim.
