Title
(EN) COOKING UTENSIL
(FR) USTENSILE DE CUISINE
Abstract
(EN)
A cooking utensil has an outer shell (11), an inner shell (12) disposed inside the outer shell forming a cylindrical wall space (16) between the outer and inner shells. The wall apace (16) is formed betwen the outer and inner shells substantially along the highest of the inner shell (12). The cooking utensil also has a first heat conductive plate (14) being in contact with an inner bottom surface of the outer shell (11) and an outer bottom surface of the inner shell (12) to allow even distribution of heat throughout the bottom surface of the inner shell. A second heat conduction plate (15) is affixed to and in contact with an outer bottom surface of the outer shell. The wall space (16) between the outer and inner shells contains ambiant air. Alternatively, the wall space defined by the outer and inner shells contains a heat conduction medium (206), such as silicon oil. A support cover (13) is configured to fit in surrounding relation to the second heat conduction plate. The cooking utensil is equipped with an inner lid (20) that fits over a flange of the inner shell and covers an opening defined by the inner shell. A cover (30) that fits over a flange of the inner shell and the lid substantially covers an opening defined by the inner shell. The cover and the lid define an air gap space therebetween for trapping heat.
(FR)
L'invention concerne un ustensile de cuisine comprenant une enveloppe extérieure (11) et une enveloppe intérieure (12), laquelle placée dans l'enveloppe extérieure de manière à former un espace entre parois cylindrique (16) entre ces enveloppes extérieure et intérieure. Cet espace entre parois (16) est ménagé entre les enveloppes extérieure et intérieure sensiblement sur toute la hauteur de ladite enveloppe intérieure (12). Cet ustensile de cuisson est également muni d'une première plaque de conduction thermique (14), placée en contact avec la surface intérieure de fond de ladite enveloppe extérieure (11) et avec la surface extérieure de fond de ladite enveloppe intérieure (12), afin d'assurer une répartition égale de la chaleur sur toute ladite surface de fond de l'enveloppe intérieure. Une seconde plaque de conduction thermique (15) est par ailleurs fixée à la surface extérieure de fond de l'enveloppe extérieure, et placée en contact avec celle-ci. L'espace entre parois (16) séparant les enveloppes extérieure et intérieure contient de l'air ambiant, ou, dans une variante, cet espace défini par lesdites enveloppes extérieure et intérieure renferme un milieu de conduction thermique (206), par exemple de l'huile de silicium. De plus, un support (13) est conçu pour venir se placer autour de la seconde plaque de conduction thermique. L'ustensile de cuisine de cette invention est en outre équipé d'un couvercle intérieur (20) destiné à être posé sur le bord de ladite enveloppe intérieure de manière à recouvrir un espace défini par cette dernière. Enfin, un couvercle supérieur (30) est posé sur le bord de l'enveloppe intérieure, ledit couvercle intérieur recouvrant sensiblement l'ouverture définie par cette enveloppe intérieure et ces deux couvercles définissant un espace d'air destiné à retenir la chaleur.
