Patent Application
20060201953
This invention refers to a practical, efficient and novel configuration for pots, pans, kitchen utensils in general, and like containers, the purpose of which is to provide the same with a heat-diffusing fluid, thus producing a uniform temperature along the walls thereof and therefore avoiding a series of inconveniences when cooking. Stainless steel is a material with low thermal conductivity and its use for manufacturing pots is extremely complex. A stainless steel pot with an uncovered bottom, for example, behaves as follows: it presents a temperature curve similar to that which appears on
It is therefore an object of the present invention to provide a container with a thermal fluid to improve the heat distribution of the container.
According to one exemplary embodiment of the container there is provided an inner container; an outer container at least partially surrounding said inner container; and a chamber between said inner container and said outer container; wherein said chamber is at least partially filled with a thermal fluid with high thermal conductivity.
According to another exemplary embodiment a container is provided with an inner wall; an outer wall with at least portions spaced apart from said inner wall; and a chamber defined between said inner wall and said outer wall; wherein said chamber is at least partially filled with a thermal fluid with high thermal conductivity.
According to another exemplary embodiment a container is provided with an inner container; an outer container at least partially surrounding said inner container and including a bottom surface with at least one groove which defines at least one fin; a chamber between said inner container and said outer container; and an autogenous seal for sealing said chamber; wherein said chamber is at least partially filled with a thermal fluid with high conductivity.
The above and other objects, features and advantages of the invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings in which:
Exemplary embodiments of the invention will now be described below by reference to the attached Figures. The described exemplary embodiments are intended to assist the understanding of the invention, and are not intended to limit the scope of the invention in any way.
In order to solve all the above inconveniences, the applicant has conceived a system for manufacturing cooking utensils which produces containers with a total diffusion of the heat they receive, therefore considerably improving food cooking conditions.
As it may be observed in
a) food is now cooked as in “bain-marie”, but with a temperature which may be regulated;
b) the need for food to be stirred or mixed during cooking is dramatically reduced;
c) the container now behaves as if it were lined in a nonstick material, but avoiding the inconveniences of such materials;
d) the thermal fluid transmits heat in a uniform way, which allows for a significant economy;
e) this container has an excellent performance with fried foods, since it prevents oxidization of edible cooking oil;
f) it has a higher thermal inertia, which causes foods to be heated during a longer time while they are inside the container,
The fins of the exemplary embodiment (5) which increase the heat exchange surface, are also less energy-consuming, and even ensure that the container's bottom will keep its shape.
The exemplary embodiment of this novel container is extremely safe, even when heated over a flame without any contents, since its shape is not altered and the air chamber (3) will absorb any expansions in the fluid (7), thus keeping the container intact for years. This container may be taken straight from the freezer to the stove without any trouble, and will accept all types of heating, such as gas, electricity, wood, etc.
This invention has been described herein in considerable detail in order to comply with the Patent Statutes and to provide those skilled in the art with the information needed to apply the novel principles and to construct and use such specialized components as are required. However, it is to be understood that the invention can be carried out by specifically different equipment and devices, and that various modifications, both as to the equipment details and operating procedures can be accomplished without departing from the scope of the invention itself.
