Description

[0001] The invention relates to an arrangement for thermally insulating a cooking pot from the environment, having a pot base and pot side walls, comprising a flat insulating material for application to the pot side walls of the cooking pot.

[0002] Cooking pots are used for preparing food. They are placed on a stovetop, such as a gas stove or an electric stove with a ceramic or induction hob. In either case, heat is transferred into the pot through its base to warm or heat the food inside.

[0003] Heat introduced into the pot is lost through the sides of the pot. Heat can escape from the already heated food, and a large portion of the heat conducted from the bottom of the pot to the sides also escapes into the environment.

[0004] To counteract this, arrangements of the type mentioned above have already been demonstrated. For example, flat insulating materials were applied to cooking pots, for example, in DE 20 2014 001 976 U1. The insulating materials used there were manufactured to fit the cooking pot, allowing them to cling to it.

[0005] This connection between the insulating material and the cooking pot is inadequate. Especially with hot stoves, such as electric or gas stoves, it is important to prevent the insulating material from coming into contact with the heat source. The insulating material must not sink to the level of the bottom of the cooking pot, resulting in it resting on a hot source.

[0006] The invention is based on the object of demonstrating an arrangement for thermally insulating a cooking pot of the type mentioned at the outset, in which the insulating material is securely applied to the cooking pot.

[0007] This object is achieved according to the invention in that the insulating material is applied to the pot in the area of ​​the pot base and in the area of ​​the opening edges of the pot side walls and is connected to the pot in a gas-tight manner

[0008] The inventive arrangement does not aim for a flat, snug fit of the insulating material to the cooking pot; rather, special fastening means are provided. These fastening means are evident in the proposed gas-tight connection between the insulating material and the cooking pot. The insulating material is connected to the pot in the area of ​​the pot base and in the area of ​​the opening edges of the pot side walls. Thus, the insulating material lies flat against the entire side wall of the pot and can provide thermal insulation.

[0009] This allows for a secure placement of the insulation material on the pot, effectively preventing it from slipping into the heat source.

[0010] According to a first refinement of the invention, the insulating material is designed as a hollow cylinder whose diameter is larger than the diameter of the cooking pot. The hollow cylinder has an inner diameter that is slightly larger than the outer diameter of a cooking pot for which the insulating material is to be used. The cooking pot can, for example, be inserted into the hollow cylindrical insulating material from above.

[0011] According to a further development of the invention, the insulation material is connected to the cooking pot by soldering. This soldering can be performed around the outer surface of the pot side walls, so that closed solder seams are formed in the area of ​​the opening edges of the pot side walls and in the area of ​​the pot base. This ensures a gas-tight connection between the insulation material and the cooking pot. Alternatively, welding can also be provided.

[0012] Due to the gas-tight connection, the insulating material can be provided with a cavity. The insulating material can be designed as a hollow body, such as a double-shell casing for the pot side walls. The cavity can be filled with a gas, for example, air, which is a good thermal insulator.

[0013] The cavity can also be filled with a solid material. This can be made of composite materials with high thermal insulation or aerogel materials with high thermal insulation.

[0014] An embodiment of the invention is shown in the drawing, in which: Fig. 1: a sectional view of a cooking pot with an insulating material according to a first embodiment, and; Fig. 2: a sectional view of a cooking pot with a further insulating material according to a second embodiment

[0015] The cooking pot 1 in Fig. 1 has pot side walls 2 and a pot base 3. Handle elements 4 are assigned to the pot side wall 2.

[0016] An insulating material 5 is assigned to the cooking pot 1. This insulating material 5 rests against the pot side walls 2, and the insulating material 5 encircles the cooking pot 1.

[0017] The insulating material 5 itself is double-shelled, comprising two insulating material walls 6. A cavity 7 filled with a gas is arranged between the insulating material walls 6. The gas does not escape from the insulating material 5 because the insulating material 5 is firmly attached to the cooking pot 1 via solder joints 8. One solder joint 8 is located at the level of the pot base 3, and another solder joint 8 is located directly on the underside of the bent opening edge 9 of the pot side walls 2.

[0018] In Fig.2, the vertical cross-section of the insulating material 5 is trapezoidal, with the result that the thickness of the insulating material 5 increases toward the pot bottom 3. A solid, heat-insulating insulating material 10 can be arranged in the cavity of the insulating material 5 between the insulating material walls 6. QUOTES CONTAINED IN THE DESCRIPTION
