Abstract

The proposed insulated vessel for cooking food consist of a saucepan receiving element (a) and a lid (1), the element having a smaller diameter than the lid. Thus, in use, an annular slit is arranged between the lid and the receiving element. In order to withstand high thermal stresses the receiving element (2) comprises a second receiving element (3) which, by means of ribs (8), provides an air passage (9) between both elements. The lower part of the receiving element (2) has one or more outlets as well as an annular rim provided with slits (6).

Description

 Insulating container for baking food

A device for cooking food is proposed, which represents an insulating vessel, consisting of an upper and lower part, which are separated from one another by a separating joint, the separating joint being arranged in the lower third of the total height of the insulating vessel. The insulating container is made of closed-cell foam with a density between 35 and 200 kp / m 3 . The lower part and the upper part can be designed so that the ratio of inner diameter to inner height is greater than 1: 0.5 (P29 25 316.5).

The insulating container is made of foam-foamed plastic, such as phenolic resin, polystyrene, polyurethane or polyvinyl chloride. A closed plastic foam with a density between 45 and 100 kp / m 3 is preferred. This design of the insulating vessel allows several pots to be placed one above the other in the vessel, so that smaller and different dishes can also be cooked. The selected foams allow the temperature resistance to be chosen between 60 and 100 ° C, especially at 110 ° C.

According to another older proposal (P 29 40 346.1), an insulation device for cooking food is proposed in improvement, the lower insert having a smaller outside diameter than the inside diameter of the hood and thus an annular gap being present when ready for use. The ratio of the outer diameter of the lower insert on its upper side to the inner diameter of the hood on the underside is 32: 33.2 to 35. It has also been suggested that an insert washer be made on the inside of the base attach heat-resistant material, provide recessed grips and form the inside of the hood so that measured at least from the lower edge to half the height, preferably half to two thirds, is cylindrical.

The disadvantage of these older proposals is that they cannot withstand more severe thermal stresses,

The object of the invention was thus to improve the existing and to create a device that allows not only the cooking of food, but also the baking.

The invention therefore relates to an insulating vessel for baking, consisting of an insert and a hood, which is characterized in that a further insert is provided in the insert, which is inserted into the insert via ribs and thus forms an air gap via ribs . One or more holes are provided in the bottom part of the insert, which allow air ventilation between the element and the inner wall of the insert. The insert shows an annular bead that has slots.

The hood has a layer on the inside, which consists of an insulating layer and a heat-conducting layer.

The invention will be explained with reference to the drawings

Fig. 1 shows the cross section of the overall device and Fig. 2 shows the top view of the insert

he purify.

The device according to the invention consists of a hood 1 and an insert 2. A further insert 3 is provided in the insert 2, which is mounted on ribs 8 and, as can be seen from FIG. 2, in such a way that an air gap 9 is created. The ribs 8 are preferably arranged in a star shape and do not extend to the center. The insert 3 represents a metallic shape adapted to the insert 2, preferably in a thickness of 0.3 to 1.5 cm. The metal used here is said to be a heat-resistant material, for example aluminum, steel, stainless steel, glass, aluminum and its alloys being preferred.

In insert 2 there are holes in the bottom part, i.e. At least one hole is provided, which should then be central, but several holes can also be arranged depending on the sectors of the ribs.

The insert 2 has an annular bead 5 which has a plurality of slots 6, that is to say approximately from 2 to six. Depending on the size of the holes, there may be more.

A pot (or several) 13 is then placed on the insert 3 made of metal or glass, as required. The insert 3 is necessary to bring about heat regulation at the temperatures necessary for baking. The baking temperatures are over 100 C, so that there is a risk that the plastic used will melt and the insert 3 will burn out. The air entering the vessel through the slots 6 and the bores 7 circulates between the plastic wall of the insert 2 and the insert 3 in the gap 9 and rises. Excess air can escape to the outside in the gap between insert 2 and hood 1

The hood 1 is designed in the manner already proposed, but shows fiction, in this preferred According to the embodiment, an inner lining, ie a heat-resistant insulation 11, 12. The layer 11 is made of an insulating material, for example glass or mineral or asbestos, on which the support 12 is arranged, of a heat-conducting material, heat-radiating material, such as aluminum, steel and other similarly acting material, aluminum and its alloys being preferred .

The device according to the invention not only makes it possible to carry out the proposed cooking, but also to carry out a briefly heated baking of cakes, bread, cookies and the like, which is associated with energy savings and time savings for the housewife. It is surprising that this not only enables baking, but also that the desired topping is achieved for the baked goods, that is to say the browning of bread.

So this is not a pure warming jar, as has been known for a long time, but a jar for saving energy and for baking.
