Abstract
Provided is a kitchenware item comprising a pot comprising a metal substrate (31), and a power supply source (7) connected to a heating electrical resistance (9) with which the pot is provided. The electrical resistance is arranged in the region of the side wall (300) of the pot: either outside the metal substrate, or embedded in said substrate, within either a moulded electroconductive metal material or a plurality of electroconductive metal layers that are interconnected, without adhesive, by deformation and/or physicochemical metal connection.
Claims20
Cooking pot (1) which includes:
- a pot designed to hold food which includes substrate (31) with bottom (30) and side wall (300) on the periphery of bottom (30), and heating electrical resistance (9) near side wall (300) of the pot,
- electricity source (7) connected to electrical resistance (9) for electrical power, in which substrate (31) is metallic and electrical resistance (9) is located:
- either on the outside of the substrate, or
- incorporated into said substrate, within:
- either cast electrically conductive metallic material (3a1), or
- several electrically conductive metallic layers (3a1, 3a2, 3a3, 3a4, and 3a5), interconnected without adhesive by deformation and/or a chemical-physical metallic bond.
Procedure for manufacture cooking pot (1) with a pot which includes substrate (31) designed to hold food on its internal surface (13), in which the procedure includes a recessed substrate placement phase so that it then has bottom (30) and side wall (300) on the periphery of the bottom, in which substrate (31) has at least one metallic layer (3a1, 3a2, 3a3, 3a4, and 3a5) and, prior to or after the recess formation stage, heating electrical resistance (9) is attached near side wall (300), on external periphery (30a1) of metallic layer(s) (3a1, 3a2, 3a3, 3a4, and 3a5) of this side wall (300) and said resistance (9) is connected to electrical power source (7) on the cooking pot.
Procedure to manufacture cooking pot (1) with an pot which includes substrate (31) to hold food on internal surface (13), wherein the procedure includes a stage where the substrate is formed into a recess so that it has bottom (30) and side wall (300) on the periphery of the bottom, in which substrate (31) has at least one metallic layer (3a1, 3a2, 3a3, 3a4, and 3a5), and either:
- heating electrical resistance (9) is incorporated into this substrate (31) when the recess is formed, or
- prior to or after the recess formation phase, said resistance (9) is placed between said two electrically conductive metallic layers (3a1 and 3a2) which the substrate then contains, and this resistance (9) is incorporated into that substrate,
- and said resistance (9) is connected to electrical energy source (7) with which the cooking pot is equipped.
