[0003] From the document US 2010 / 0116819 A1 a cooking utensil with an induction coil for transmitting electrical energy to the cooking utensil is known.

[0004] US 2009 / 0065500 A1 discloses a double-walled cooking utensil with an insulating material between the two walls. Another cooking utensil is known from CA 2 924 864 A1.

[0005] The invention addresses the problem of improving such a cooking utensil. According to the invention, this problem is solved by a cooking utensil having the features of patent claim 1. The cooking utensil according to the invention can be freely selected in terms of type, function, material, dimensions, and shape within wide suitable limits. For example, the cooking utensil can be a saucepan, a roasting pan, or a frying pan. The cooking utensil according to the invention can be designed for use on an induction hob, a gas hob, or a solid-state hob with a radiant heater. The cooking space of the cooking utensil according to the invention, which is open at the top when the cooking utensil is in use, can be covered by a lid or the like during use of the cooking utensil, for example during the cooking process using the cooking utensil, in a manner known to those skilled in the art.However, this is not mandatory and is applied by a user of the cooking utensil depending on the requirements of the individual case. The at least one handle can, for example, be designed as an integral component of the outer shell in the cooking utensil according to the invention. It is also conceivable for the at least one handle to be designed as a separate component, wherein the handle is connected to the outer shell in a manner known to those skilled in the art during the manufacture of the cooking utensil according to the invention, i.e., during its transfer into its assembled state. Advantageous embodiments and further developments of the invention emerge from the following subclaims.

Furthermore, it is possible to provide a hollow space between the outer shell on one side and the inner shell on the other side, which can then, for example, be used additionally for at least one further function.

[0007] A particularly advantageous development of the cooking utensil according to the invention provides that the inner shell is detachably connected to the outer shell in the assembled state of the cooking utensil. Preferably, the inner shell and the outer shell have mutually corresponding form-locking means for forming the detachable connection. Particularly preferably, the mutually corresponding form-locking means are designed as bayonet closure means for forming a bayonet closure. This makes it possible, on the one hand, to use one outer shell for a plurality of inner shells. This is a significant advantage, for example, in the production process, since it allows a large number of variants of cooking utensils according to the invention to be covered with a single type of outer shell. For example, the inner shells of the respective cooking utensils according to the invention can differ in whether they are equipped with or without a non-stick coating.The inner shells of such cooking utensils according to the invention can also differ in the material used, for example, stainless steel. On the other hand, such a combination of an outer shell with a plurality of corresponding inner shells is also conceivable for the user. For example, the user could change the inner shell of the cooking utensil according to the invention depending on the requirements of the individual case. Such inner shells could also be sold at a significantly lower price than a complete cooking utensil according to the invention.

[0008] The detachable connection between the outer shell and the inner shell can be realized in any sensible manner known to those skilled in the art. The preferred embodiment of this development further has the advantage that the detachable connection is realized in a simple and robust manner in terms of design and production technology. In addition, the particularly preferred embodiment of this development has the further advantage that the inner shell can be connected particularly intimately to the outer shell by means of the bayonet lock, since the inner shell can be firmly tightened to the outer shell during production of the bayonet lock.

[0016] According to a further variant, the cooking utensil according to the invention provides that the cooking utensil has at least a plurality of sensors connected to a control of the cooking utensil in a signal-transmitting manner.

[0017] This enables the detection of cooking utensil parameters and / or cooking product parameters, such as the temperature of the inner shell of the cooking utensil, with the at least one sensor being structurally associated with the outer shell. Thus, the division of the cooking utensil according to the invention is advantageously utilized from a functional perspective, since the inner shell can be designed accordingly more freely.

[0018] One aspect is that the at least one sensor is arranged on an inner wall side and / or inner base side of the outer shell, each facing the inner shell; it is particularly preferred that the at least one sensor is elastically arranged on the outer shell. This has the advantage that the sensor is, on the one hand, protected from environmental influences that impair the function of the sensor and, on the other hand, can be arranged on the outer shell in close contact with the outer shell and / or the inner shell. This applies in particular to the particularly preferred embodiment of this development. An elastic arrangement of the at least one sensor on the outer shell means that the at least one sensor is arranged on the outer shell so that it can move elastically relative to the outer shell.

[0019] According to a further variant, the cooking utensil according to the invention provides that the cooking utensil has a plurality of sensors, in particular that the at least one sensor is designed as a plurality of sensors, wherein the plurality of sensors are distributed over a height of the inner wall of the outer shell. The use of a plurality of sensors enables high-quality detection of the aforementioned parameters. In particular, it is provided that the cooking utensil has at least two sensors. According to a preferred embodiment, a number of 3 to 9 sensors is provided, which are in particular equidistant from one another.

[0020] The plurality of sensors are arranged on a wedge that diverges towards the bottom of the outer shell, in particular wherein the wedge is designed as an elastic wedge and is fastened to the outer shell and / or is elastically fastened to the outer shell. In this way, the cooking utensil parameter and / or food parameter detected by the at least one sensor, for example the aforementioned temperature of the inner shell of the cooking utensil according to the invention, can be determined distributed over the height. Secondly, the sensors arranged distributed over the height come into intimate contact with the inner shell of the cooking utensil according to the invention by means of the wedge, despite, for example, any component tolerances, so that high-quality detection of the aforementioned parameters is possible by means of the entirety of the sensors.

[0021] This design of the cooking utensil is particularly suitable in conjunction with the further development according to which the inner wall side of the outer shell facing the inner shell in the assembled state of the cooking utensil and the outer wall side of the inner shell facing the outer shell in the assembled state of the cooking utensil are each designed to be conical in a corresponding manner to one another.

[0022] Another advantageous development of the cooking utensil according to the invention provides that, in the assembled state of the cooking utensil, a thermal insulation means is arranged between the outer shell and the inner shell. Preferably, the thermal insulation means is arranged between an inner base side of the outer shell and an outer base side of the inner shell. Particularly preferably, the thermal insulation means is designed as an aerogel. This enables thermal decoupling of the outer shell on one side from the inner shell on the other side in a structurally and manufacturing-technically simple manner. This applies particularly to the preferred and, in particular, to the particularly preferred embodiment of this development.Such thermal decoupling is useful or even necessary, for example, when a cookware according to the invention designed as an induction cookware is to be operated on a cooktop designed as a fully integrated induction hob.
