Abstract

The invention relates to a kitchen utensil with a lid for preparing food. According to the invention, the flat bottom 2 of the utensil 1 comprises, in the outer zone, several projections 3, the lower ends 3 'of which are located in a plane parallel to the bottom; on the outside of the projections 3, the bottom comprises a circular cavity 4, the height of which is less than the height of the projections 3; between the circular cavity 4 and the upper edge 6 extends the wall 5 thereof, curved outwards; the edge 8 of the cover 7 is bent downwards, protrudes outwards beyond the edge 6 of the utensil 1 delimiting the volume provided for the food, such that it results between this edge 6 and the edge of cover 7 an intermediate volume provided for the entry of air into the utensil.

Description

The invention relates to a kitchen utensil with a lid for preparing

  food. A large number of kitchen utensils with a lid are already known. In most modern cookware, intended for use on electric stoves or cooking plates, the bottom is flat on the outside and, to prevent it from being deformed by heat, it is relatively thick; for this reason, these kitchen utensils are

relatively expensive.

  Also known from US-PS 12 77 579 are kitchen utensils designed so that it forms between their bottom plate and the upper face of the. electric hob a cushion of air and that heated air

  is guided inwards by a central tube shaped like a

TONNOIR.

  The object of the present invention is to obtain, by a new configuration of the kitchen utensil and its associated lid, a rational and efficient heating of food to be cooked thanks to a current of hot air, even with all the varieties. of food for which the central tube

  funnel-shaped had been annoying.

  This object is achieved with a kitchen utensil of the type mentioned above, according to the invention by the combination of the following characteristics: a) the flat bottom of the kitchen utensil comprises, in the outer zone, several protrusions projecting towards bottom, disposed substantially along an arc of a circle, the lower ends are in a plane parallel to the bottom;

  (b) on the outside (in relation to the center of the utensils

  the kitchen) projections, the bottom has a circumferential cavity

  the height of which is less than the height of the

  lie, so that the lower side of these projections, in po-

  in the area of the circular cavity c) between the circular cavity and the upper, substantially vertical edge of the cooking utensil, extends the wall of the kitchen curved towards the floor. outside -2-

  (d) the edge of the lid is bent downward, out-

  outward beyond the edge of the marking utensil

  the volume intended for the food, so that between this edge and the edge of the lid there is an intermediate volume intended for the entry of air into the utensil and provision is made for a means of support for the lid, which covers the intermediate volume between the edge of the lid and the edge of the cooking utensil e) the lid has several holes in the

central area.

  The invention will be well understood on reading the

  detailed description, given as an example only, of a

  embodiment shown schematically in the drawings

annexed, on which

  - fig. 1 is a longitudinal sectional view through

  towards the right half of a kitchen utensil with cover

  key; - fig. 2 schematically shows the arrangement of projections projecting downwards from the flat bottom of the kitchen utensil; and, - fig. 3 shows, in view from below, a detail

  part of the edge area of the lid.

  The kitchen utensil l has a flat bottom 2 which has in its outer zone 4 protrusions 3 projecting downwards. These projections 3 are arranged, as shown in the schematic drawing of FIG. 2, at regular intervals

along an arc.

  The lower ends 3 'of the projections are in a plane parallel to the bottom 2. Outside - with respect to the center of the cooking utensil - projections 3, the

  bottom has a circular cavity whose height is less than

  greater than the height of the projections 3, so that there remains between the outer side of the cavity 4 and the upper side of the cooking plate K, used for heating, an intermediate volume. If the cooking utensil is used for grilling, the fat falling in drops

  gathers inside the projections 3 and in the circumferential cavity

4.

  Between the circular cavity and the upper ver-

  6 of the utensil 1 extends the wall 5 thereof,

  curved outward. The edge 8 of the lid 6 of the usten-

  if it strikes outwards 1 to 2 cm. This edge 8 of the neck

  7 is provided with inwardly projecting support elements 9 covering the intermediate volume 12 between the

  edge 8 of the lid 7 and the edge 6 of the utensil'1. In po-

  these support elements 9 are based on

  the edge 6 of the utensil 1. The free ends 10 of the ele-

  9 are bent downwards, in the example shown, and thus constitute abutments which prevent the

  cover to slide horizontally.

  The heated air in the intermediate volume between the

  bottom 2 and the cooking plate K will flow between the

  3, along the outwardly curved edge 5, under

  of laminar flow directed upwards, and by the

  intermediates me 12, it will reach the interior of the usten-

  covered with the lid 7. When heating the food to be cooked or roasting in the utensil, these foods are not heated only from below by the bottom 2 and the wall 5, but also from above by the hot air penetrating through the intermediate volume 12. The hot air which, with the usual kitchen utensils, is evacuated

  in the kitchen after passing along the side wall

  the, is here reused to heat the upper side of food. This is particularly important in

concerns energy savings.

  After the air has given up heat to the food, it escapes upward through the openings 13 in the lid 7. This ensures a continuous air flow between the cooking plate K and the upper side of the food. . The lid 7 is provided with a handle 14, the utensil 1 with a

tail 15.

  Fig. 3 is a bottom view of a portion of the neck.

  circle 7 in the area of a support element 9.

  The lid support elements may be

  caused by indentations in the lid.
