Cooking appliance exposable to temperature intervals with an electrically conducting, magnetizable coating, device and method of coating of at least one cooking appliance

摘要

The cooking device interruptible at temperature intervals of 100[deg] C, comprises an electrically conductive magnetizable coating, which serves for induction heating, on a bottom outer side of the cooking device, where a thermal expansion coefficient of a material of the electrically conductive magnetizable coating is 35-55% less in relation to the remaining of the cooking device bottom. The coating on the bottom outer side lies with a porous area, which acts as dilatation balancing area. The basic material of the cooking device is a dignified aluminum, aluminum alloy or cast aluminum. The cooking device interruptible at temperature intervals of 100[deg] C, comprises an electrically conductive magnetizable coating, which serves for induction heating, on a bottom outer side of the cooking device, where a thermal expansion coefficient of a material of the electrically conductive magnetizable coating is 35-55% less in relation to the remaining of the cooking device bottom. The coating on the bottom outer side lies with a porous area, which acts as dilatation balancing area. The basic material of the cooking device is a dignified aluminum, aluminum alloy or cast aluminum and the electrically conductive coating is iron or stainless steel. A porous adhesive layer acts as dilatation balancing area between the electrically conductive coating and the bottom outer side and has a layer thickness of 0.1-0.5 mm. The electrically conductive coating has the closely self-circulating dilatation balancing area with a width of 0.5-5 mm and a layer thickness of 0.1-0.5 mm. The electrically conductive coating acting as the dilatation balancing area has a porosity of 10-20% and the still uncoated bottom outer side has a roughness of RA12-16. A primer is applied as adhesive layer on the bottom outer side for the electrically conductive coating. Independent claims are included for: (1) a system for coating a surface of a cooking device; and (2) a method for coating a cooking device.
