Embodiment Construction

[0029] In order to have a more complete and clear disclosure of the invention purpose, technical means and technical effects of the present invention, a detailed description is given below, and please also refer to the accompanying drawings and component numbers.

[0030] Referring to FIGS. 1 to 6 , wherein like reference numerals indicate like components in the different views, there is illustrated a new and improved partially insulated cooking appliance, generally indicated herein at 100 .

[0031] The cooking appliance 100 according to the invention has a bottom cooking surface 101 directly exposed to a heat source. A vertical wall 102 connects to and surrounds the bottom 101 and extends upwards to an edge region 103 . The lower portion 134 of the vertical wall 102 is a layered structure having three layers 130 , 120 and 110 . In the upper portion 136 of the wall 102, the outer layer 130 is separated from the more thermally conductive inner layer 120 to form a cavity 135 i...

Abstract

A cookware vessel has an upper portion of the surrounding sidewall that is insulated by a cavity to maintain the temperature of the food cooked therein until and during the service of food from the vessel. A highly conductive metal layer, such as a copper layer, extends upward along the inner wall surface adjacent to the inner vessel to spread heat from the bottom of the vessel up the inner sidewall. The copper layer is bonded to the both the inner and outer vessel at the bottom of the vessel and portions of the outer sidewall that would otherwise be overheated by a burner flame and then discolor. In a preferred embodiment, the brazing compound comprises silver to further improve thermal conduction. The copper layer may also extend to the bottom exterior of the vessel to provide an improved means from measuring the temperature of the contents during cooking.

Description

[0001] Related Application Cross Reference [0002] This application claims priority to the identically titled US Provisional Patent Application No. 61 / 590,798, filed January 25, 2012, and is hereby incorporated by reference. technical field [0003] The invention relates to a cooking utensil, in particular to a partially heat-insulated cooking vessel. Background technique [0004] The present invention relates to a cooking appliance, and in particular pots and pans, having a double wall construction, wherein the gap between the double walls provides thermal isolation. [0005] Previous forms of hollow wall cooking vessels have internal cooking properties, providing insulation as the side walls are not heat conducting, so that most of the heating of the food comes from the bottom of the cooking vessel. [0006] This construction is susceptible to excessive heating of the exterior of the hollow wall closest to the heat source or flame and, in the case of stainless steel, qu...
