Abstract:
1. Improved lid assembly for covering a food cooking container, comprising: a lid defined by i) a lid lower surface layer configured to be placed on an upper edge surface of the cooking container, the lid lower surface layer having an outer perimeter edge, ii) a lid upper surface layer having an outer perimeter edge, a lowermost surface of said lid upper surface layer being spaced apart from an opposite uppermost surface of the lid lower surface by an interspace located therebetween, the lid upper surface layer having an outer perimeter edge, the lid lower surface layer and the lid upper surface layer being coupled in correspondence at the outer perimeter edges, and wherein the interspace between the lid lower surface layer and the lid upper surface layer defines a vacuum chamber iii) plural channels present on the lid upper surface layer, wherein with the lid located on the cooking container within which food is being cooked, the channels communicate an interior part of the cooking container with the surrounding outside environment, each channel is created by a pair of holes located respectively on the lid lower and upper surface layers, an outer surface of each channel being comprised of a cylindrical element having a profile starting from the lid upper surface layer extending to the lid lower surface layer, the channels providing passage paths capturing and accelerating an outlet speed of cooking vapors from the interior part of the cooking container into a vapor condensing space located above the lid upper surface layer, wherein the interspace defined between the uppermost surface of said lid lower surface layer and the lowermost surface of said lid upper surface layer defines therebetween a thermally insulating space insulating the interior part of the cooking container from an exterior of the cooking container; a vapor cooling means comprised of a lid-cover located outside the cooking container and above said lid; and a support element supporting said lid-cover above said lid, wherein, the vapor condensing space is defined between a lower surface of the lid-cover and the lid upper surface layer, the lower surface of the lid-cover being in vertical registration with the channels, vapor coming from the interior part of the cooking container are accelerated through said channels to a lower surface of said lid-cover, contact with the lower surface of the lid-cover condensing the vapor, and the condensed vapor flowing again, at a liquid phase, into said cooking container through said channels.
