SK612590A3 - A container for heating or cooling foods or liquids - Google Patents

Description

Technical field

The invention relates to a container for the preparation, heating and cooling of food and beverages, the insulating function of which, in addition to the thermal insulating materials, is also filled by an air-filled cavity.

BACKGROUND OF THE INVENTION

In addition to single-walled kitchen utensils, double-walled kitchen utensils are used for the preparation and heating of food and beverages by combining the use of thermally well conductive materials with thermally insulating materials.

Two-walled kitchen containers are known, formed from a double-walled cladding and a double-walled bottom. The space between the inner and outer walls of the cladding and the double-walled bottom is usually filled with water or other liquid

Known are also double-walled kitchen utensils, made only of double-walled cladding and single-walled bottom. The intermediate space formed between the outer and inner walls of the peripheral shell of such containers is filled, as a rule, with various insulating materials to prevent heat escape into the surroundings of the containers.

A disadvantage of the previously known double-walled kitchen containers is that they do not sufficiently prevent heat escape into their environment and that their purpose is only to prepare or heat meals and drinks and not to cool them.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION The invention is based on the fact that by providing a cavity between the skirt and the inner skirt walls, the insulating properties of the container are increased. The possibility of filling the cavity with coolant creates conditions for the multipurpose use of the container, in particular for cooling food and beverages.

The vessel for heating or cooling food or liquids consists of inner circumferential walls encased in a peripheral shell.

The inner peripheral walls and the bottom are made of a good thermally conductive material such as e.g. steel, cast iron, etc.

The cladding of the vessel is constructed such that the interspace between the outer and inner walls of the cladding is filled permanently with a layer of heat insulating material, or air or gas. The outer and inner walls of the cladding are connected to each other by pressing, welding or gluing along their upper and lower perimeter. At the same time, the inner and outer walls of the cladding are interconnected by a tube extending through the intermediate space, one end of which flows into the cavity and the other into the pouring spout. The function of a double-walled cladding can also be performed by a single-walled cladding made of a thermal insulating material such as e.g. ceramics, or a single-wall cladding, coated on the inside with a layer of thermal insulator. In such an embodiment, the tube connecting the outer and inner walls of the cladding to the cavity is replaced by an opening opening into the pouring spout.

The cavity between the skirt and the container itself is filled with air when preparing and heating food and drinks, while cooling it with cold water.

The construction of a container for heating or cooling food or liquids according to the invention reduces the heat energy consumption for the preparation and heating of food and beverages, while allowing them to cool.

In FIG. 1 shows a container for heating or cooling food or liquids in front view. In FIG. 2 to 4 show examples of a possible embodiment of the invention.

Example (s) of the invention

The container for heating or cooling food or liquids of FIG. 1, is formed of inner peripheral walls and a bottom 1 and a peripheral sheath 2. The inner peripheral walls 1 are surrounded by a peripheral sheath 2 all around the periphery.

The cladding 2 is shaped so that its upper and lower sides are adjacent to the inner peripheral walls L to which it is connected by pressing, welding or gluing, the thermally conductive bottom projecting over the connection point of the lower side of the outer casing 2 to the inner peripheral walls 1. 2 is formed by its outer wall 3 and inner wall 4, which are connected to each other along the entire circumference of their home and underside by pressing, welding or gluing. The outer wall 3 is connected to the inner wall 4 by a pipe 6, which leads one side into the cavity 8 and the other side into the pouring spout 7. The outer wall 3 is provided with a pouring spout 7 allowing the cooling liquid to be poured into the cavity 8. a layer of heat insulating material or air or gas. A cavity 8 opens into the cavity 8, which serves to fill the cavity 8 with water or other coolant in cases where the container is intended to cool food or beverages. In cases where the container is intended for the preparation of food requiring heat treatment, it is equipped with a cover 9 and, if necessary, with holders 10. In cases where the container according to the invention is intended only for heating or cooling beverages for direct consumption, holder of closed oval shape 11.

The function of the vessel for heating or cooling food or liquids is that the heat source transfers heat through the thermally conductive bottom to the food or beverage to be prepared, the peripheral shell 2 and the cavity 8 preventing heat escape into the environment. If necessary, to cool the food or beverage prepared or heated in the container, the cavity 8 is filled through the pouring spout 7 and the pipe 6 into full or only part with water or other coolant.

Method of industrial applicability of the invention

The subject of the invention is useful in the industrial production of cooking cooking containers intended for the preparation of food and beverages in large-capacity or domestic kitchens or containers intended for direct consumption of beverages.
