Mrs. Elfriede Jungwirth, née Götz, Mittererstraße 1, 8390 Passau Cookware, especially saucepans, frying pans, kettles, etc.

The innovation concerns a cookware, in particular a saucepan, pan, Kettle etc. with an upper opening for the crockery, a peripheral wall for the crockery and a crockery base.

Previously known cookware have the disadvantage that the walls of this Cookware has extremely poor thermal insulation, so that food in the cookware cools down very quickly or during cooking A large part of the heat energy supplied during cooking is lost, especially on the peripheral wall of the cookware in question.

The task of the present innovation is to avoid these disadvantages and to show a cookware in which at least the peripheral wall has the lowest possible thermal conductivity.

To solve this problem, a cookware is the one outlined above

^: Art according to the new design so that at least the wall of the harness is double-walled with an inner and an outer k'andab-

cut is carried out, and that the two wall sections to form an airtight or vacuum-tight space that is located between these wall sections and that surrounds the interior of the crockery are connected to one another.

The innovation according to the design of cookware can Heat flow from the interior of this cookware to the environment by evacuating the space between the two wall sections is essential reduce, which results in a very significant saving in energy and costs. At the same time, it also saves time when cooking achieved because the food in the cookware comes to a boil more quickly. Another advantage of the cookware according to the innovation is that that the once heated food remains in the cookware for a long time can be kept warm. In particular for this purpose, according to a preferred embodiment, the crockery base is in two parts, namely made of a first base part firmly connected to the peripheral wall of the harness and a second, removable base part. The first floor part is single-walled, while the second bottom part is made of two, parallel to each other arranged wall sections, which include an airtight space between them, the reduction the thermal conductivity is evacuated.

The cookware is then used for cooking or heating the food Without the second base part, a stove is placed on the fireplace or the hotplate, while the Cookware is placed with its first bottom part on the double-walled second bottom part, whereby too rapid cooling of the cook-j good is also effectively prevented in the area of the bottom of the dishes.

The cookware according to the innovation can be used both in the household and in commercial cakes are used and are also particularly suitable

for storing frozen or chilled food.

Developments of the innovation are described in the subclaims.

^! The innovation is explained in more detail below with reference to the figure, which shows a saucepan in cross section.

The saucepan 1 shown in the figure has a cylindrical shape Peripheral wall by two spaced and concentric to each other Wall sections 2 and 3 is formed. The wall sections 2 and 3 are in the area of the pot opening or the upper edge of the pot 4 and connected to one another in the region of the pot bottom 5 in such a way that between the wall sections 2 and 3 an annular, the pot interior surrounding space 7 is formed, which closes airtight from the outside sen is and can be evacuated to achieve a pot outer wall with low thermal conductivity. The pot bottom 5 consists of a first bottom part 8, which is connected to the peripheral wall of the pot or to the wall sections 2 and 3, as well as a removable, second bottom part 9. This bottom part 9 is formed by two disc-shaped wall sections 10 and 11 that are kept at a distance from one another, which are connected to one another on their circumferential surface to create an airtight, evacuable space 12. By doing the wall section 10 facing the first bottom part 8 is provided with a circular recess 13, which in its diameter corresponds to the diameter of the bottom part 8 is adapted in such a way that the bottom part 8 finds space in the recess 13, the slightly pulled down and in the recess 13 lying bottom part 8 also on its peripheral surface to achieve the best possible thermal insulation between the contents of the Pot 1 and the area around the bottom part 9 or from the edge of the

depression 13 is encompassed.

By using a two-part base (base parts 8 and 9) for the saucepan 1, it is possible to place the saucepan 1 on a fireplace or a hotplate of a stove with the base part 9 removed and to heat the contents of the saucepan 1 while keeping it warm of
The contents of the saucepan 1 with the base part 8 on the base part 9
is put on »

Like the peripheral wall and the bottom, the cover 14 is also double-walled made with two wall sections 15 and 16, one airtight and include evacuable space 17.

On the outer wall sections 2 and 15 of the peripheral wall or the cover. 14 usual handles 18 are attached.

For the production of the saucepan 1, for example, stainless steel is suitable,
Sheet copper, aluminum.

The innovation was described above using an exemplary embodiment. It is understood that modifications thereof are possible without the
Invention idea is left.
