FR2474851A1 - Thermally insulated food cooking container - has insulation around side and over movable lid and conductive base to aid heat transfer - Google Patents

Abstract

The cooking container has a movable lid (4), a continuous side wall (1) and a base (3). The outer surface of the container is thermally insulated (6-7,8-9) all around the side (1) and above the movable lid (4). The base (3) is not thermally insulated, so that good heat transfer is achieved.

Description

In the text which follows, the term "culi flaireI? Container" is used to designate, in general, all kitchen articles such as pots, pans, pots, pans, dishes or the like, in any material resistant to thermal shock, usable for preparing food, cooking food, heating liquids and, in general, all culinary operations requiring thermal energy consumption0
the present invention proposes to notably reduce the energy consumed for the execution of such culinary operations. To this end, it relates to a culinary container having, as usual, from top to bottom, a removable cover, a continuous side wall provided, if appropriate, with a draining spout and, finally, a bottom.

 be culinary container in accordance with the present inventlon earacterise by the external arrangement of a heat insulation all around said side wall and over said removable cover, while said bottom is left bare, that is to say without thermal insulation.

 The description which follows with reference to the appended drawing given by way of a non-limiting example, will make it clear how the invention can be implemented, the features which emerge both from the drawing and from the text forming, of course, part of said invention.

 The single figure is a schematic view, in two vertical half-sections juxtaposed, of a culinary container according to alternative embodiments of the present invention.

The culinary container illustrated in the drawing comprises a body of conventional composition, formed by a wall. side 1 with handles 2 and a thick bottom 3, the whole being surmounted by a removable cover 4 provided with a handle 5
According to the present invention, the thick bottom 3 intended by title placed on a heating surface (not shown) is left bare and, in any case, without thermal insulation; the other parts of the culinary container, namely the wall 1 and the cover 4, are coated on the outside with any suitable insulation which can be carried out in particular: - by double jacket 6-6a, including the intermediate space 7-7a
is either filled with air or other gas, or under vacuum; - by any layer of refractory material 8 and / or insulation
thermal 9, pray sandwiched between pa-king 1 and a
outer casing 10.

This arrangement makes it possible to eliminate the heat losses which are generated by the developed surface of the wall and of the lid of the conventional containers which bathe in the ambient air.
In addition, the food or ingredients contained in the heat-insulated container of the invention remain longer at the desired temperature without supply of calories, which allows a significant reduction in energy consumption.

 11 experience shows that, for medium or long duration cooking with the container of the invention, it suffices to bring the assembly to the prescribed temperature, then immediately cut the heat source: the thermal inertia operates the cooking alone in the internal atmosphere of the thermally insulated container.

Finally, from the point of view of dietetics, the foods thus prepared retain most of their nutritional richness (calories and vitamins) as well as all of their flavor.

Claims (1)

 CLAIM  Culinary container comprising a removable cover 4, a continuous side wall 1 and a bottom 3, characterized by the external arrangement of an insulation 6-7, 8-9, all around said side wall 1 and over said removable cover 4, while the bottom 3 is left bare, that is to say without thermal insulation, to allow good heat transmission.
