    The present invention refers to a sensor device with a sensor unit 5 intended to detect infrared radiation.
    Through the state of the art, a sensor device with a sensor unit is already known. In an operating state, the sensor unit detects the infrared radiation that comes out of a cooking product in the operating state. The measuring points of the sensor unit are arranged outside the product of
    10 cooking
    The invention solves the technical problem of providing a more reliable generic sensor device. According to the invention, this technical problem is solved by a sensor device with a sensor unit, which is intended to detect the outgoing infrared radiation of at least one cooking product, where the sensor unit 15 has at least one measuring point that is intended to be reversibly introduced into at least one cooking product. The sensor device is a device that in at least one operating state is intended to be used in a cooking process caused and / or caused by at least one heating element of at least one cooking appliance, and which is provided to detect in the cooking process at least one sensor parameter. The sensor device could be made as an accessory device for the cooking appliance, and intended to be equipped later. Alternatively, the cooking apparatus could comprise the sensing device, where the cooking apparatus and the sensing device could be marketed jointly. The sensor unit is a unit 25 which has at least one detector to detect at least one sensor parameter, and which is intended to emit a value that characterizes the sensor parameter, where the sensor parameter is advantageously a physical variable and / or chemistry Infrared radiation is electromagnetic radiation of a wavelength range between 780 nm and 0.3 mm. The measurement point is a surface space area of the sensor unit through which infrared radiation enters for detection in at least one operating state, and which is intended to absorb and / or detect infrared radiation. In at least one operating state, the measuring point is disposed within the cooking product. Out of a state of
    image2
    cooking.
    Through the embodiment according to the invention, great reliability can be achieved. In particular, it is possible to achieve high measurement accuracy. Particularly advantageously, the detection of infrared radiation can occur at critical points of the cooking product that require a particularly long cooking time, whereby optimal cooking results can be achieved. Also, a low cost for the development of the sensor device can be achieved. With the sensor device, a new feature can be offered to the customer and / or the user, so that great comfort for the customer and / or the user and / or an advance with respect to the competition can be made possible.
    Likewise, it is proposed that the sensor unit has at least one waveguide, which carries infrared radiation from the measuring point from the cooking product in at least one operating state. In at least the assembled state, the waveguide could connect the measuring point and at least one sensor unit detector to each other to a large extent or completely. The waveguide is an element that in at least one state of operation transmits, in particular, transport, the infrared radiation in the longitudinal direction of the waveguide, by total reflections within the waveguide. In at least one operating state, the waveguide largely or completely prevents at least the output of at least the infrared radiation in at least the directions oriented essentially perpendicular to the longitudinal direction. In this way, the incorporation of at least one detector and / or at least one electrical and / or electronic component within the cooking product can be dispensed with.
    The waveguide could be made at least essentially rigid. In particular, the waveguide could be provided to be introduced into the cooking product, without being provided with a coating. However, preferably, the sensor unit has at least one at least essentially rigid insertion element, within which the waveguide is partially or completely arranged and, preferably, largely or completely, at least In the assembled state. The insertion element is intended to be partially introduced into the cooking product. At least in the assembled state, the insertion element advantageously surrounds the waveguide by at least a large part of the longitudinal extension of the waveguide. The term "longitudinal extension" of an object includes the concept of the extension of the object along the direction of the object is a direction oriented parallel to the larger side of the smaller imaginary geometric parallelepiped that completely wraps around the object. By extension of an object it refers to the maximum distance between two points of a perpendicular projection of the object on a plane. The insertion element is composed largely or completely of at least one material that is at least essentially rigid. By way of example, the insertion element could be composed largely or completely of at least one ceramic, which could have a high resistance with respect to mechanical stress. Alternatively or additionally, the insertion element could be composed largely
    image3
    or completely by at least one metal, such as aluminum and / or stainless steel. The term "rigid" includes the concept of immobile and / or inflexible and / or hard and / or non-folding and / or firm. The waveguide is partially or completely disposed within the insertion element at least in the assembled state, that is, at least in the assembled state, the waveguide may be disposed within the insertion element in a percentage by weight and / or volume percentage of at least 30%, at least 60%. The expression “largely or completely” includes the concept of at least 70%, at least 95%. In this way, the waveguide can be arranged in a particularly protected manner. The at least essentially rigid insertion element can be introduced without problems into the cooking product.
    As an example, the insertion element could have exactly one detection recess, which could define the measurement point. Preferably, the insertion element has at least two, preferably, at least three, advantageously, at least four and, preferably, at least five detection voids, which define the measurement point and at least one other measurement point, preferably, at least two others, advantageously, at least three others and, preferably, at least four other measurement points. The sensor unit has at least one and, advantageously, the other measuring point. In this way, a large measurement area can be provided, so that high detection accuracy is possible.
    Likewise, it is proposed that the sensor device has at least one contact module, which is intended to be removably arranged next to at least one cooking battery. In at least the assembled state, the contact module is preferably provided for a force drag and / or shape drag connection with the cooking battery. As an example, the contact module could be by means of a suction cup. Advantageously, the contact module is intended to be magnetically connected with the cooking battery. The contact module could be provided, for example, to be arranged next to the lid and / or, advantageously, next to a side wall of the cooking battery. By way of example, the contact module could have at least one contact module sensor unit, which could be provided to detect the infrared radiation of the cooking battery. The contact module could, for example, have at least one contact module control unit, which could communicate in at least one operating state with the contact module sensing unit and, based on the infrared radiation detected by the Contact module sensor unit, could determine at least the cooking battery temperature. In this way, great flexibility can be achieved.
    image4
    In addition, it is proposed that the sensor device has at least one control unit, which communicates in at least one operating state with the sensor unit and, based on the infrared radiation detected by the sensor unit, determines at least the temperature of the sensor. cooking product. The control unit has at least one communication unit. The sensor unit has at least one communication unit. In at least one operating state, the communication unit of the control unit and the communication unit of the sensor unit exchange information between them. The communication unit is a unit that has at least one sender module, which is intended to send information, and / or at least one receiver module, which is intended to receive information. The control unit is an electronic unit that is preferably integrated, at least in part, into a control and / or regulator unit of a cooking apparatus, and which is intended to direct and / or regulate at least one heating element . The control unit may comprise a calculation unit and, in addition to the calculation unit, a storage unit with a control and / or regulation program stored therein, which is intended to be executed by the calculation unit. The control unit could calculate the temperature of the cooking product based on the infrared radiation detected by the sensor unit. Alternatively or additionally, the control unit could find out the temperature of the cooking product by comparing the infrared radiation detected by the sensor unit with at least one set of stored data, which in each case could assign at least one temperature at certain values of infrared radiation. In this way, a sensor can be made.
    image5
    By way of example, the contact module and the sensor unit, in particular the contact module and the insertion element of the sensor unit, could be connected to each other in at least essentially rigid way in at least the assembled state. The contact module could have at least one communication unit, which could be provided to communicate with the control unit. The control unit could be integrated in at least one cooking device and / or in at least one cooking unit control unit and, in at least one operating state, determine at least the temperature of the cooking product depending on the information received from the communication unit. Preferably, the control unit is largely or completely integrated in the contact module. There is at least any plane of the cross section in which the control unit is surrounded by the contact module with respect to the center of gravity and / or geometric center of the control unit. As an example, the control unit and the contact module control unit could be at least essentially identical. In this way, the electronics integrated in the contact module can assume several functions, in particular, the determination of the temperature of the cooking battery and the determination of the temperature of the cooking product arranged in the cooking battery.
    Likewise, it is proposed that, at least in the assembled state, the contact module and the sensor unit, in particular, the contact module and the insertion element of the sensor unit, are connected to each other in at least essentially rigid manner. In this way, particularly high stability and / or a compact embodiment can be achieved.
    As an example, at least one sensor unit detector could be largely or completely integrated in the contact module, which could be arranged next to the cooking battery in at least one operating state. The waveguide could, for example, transport the absorbed infrared radiation at the measurement point from the measurement point to the sensor unit sensor integrated in the contact module, and connect the insertion element and the detector to each other. of the sensor unit and be made as a flexible connection element. Preferably, at least in the assembled state, the contact module and the sensor unit, in particular the contact module and the insertion element of the sensor unit, are connected to each other by means of a connection element of the


    at least essentially flexible sensor unit. The flexible connection element could comprise at least one electrical cable and be provided for the electrical connection between the contact module and the sensor unit. Alternatively or additionally, the waveguide could be arranged at least partially within the connecting element and intended to drive the infrared radiation detected by the sensor unit towards the contact module and / or towards the control unit integrated in the module of contact and / or towards a detector of the sensor unit integrated in the contact module. As an example, the communication unit of the sensor unit and the communication unit of the control unit, in particular in the case of a control unit integrated in the contact module, could communicate with each other via the element of connection in at least one operating state. Alternatively or additionally, the communication unit of the sensor unit and the communication unit of the control unit could communicate with each other wirelessly in at least one operating state, such as via Bluetooth and / or infrared radiation. In this way, by maintaining the connection with the contact module, the sensor unit can be moved flexibly with respect to it, so that the insertion element can be introduced at least partially into a cooking product with flexibility and, advantageously, at different points.
    Particularly high detection accuracy can be achieved by means of a cooking apparatus, in particular, by means of a cooking field and, advantageously, by an induction cooking field, with at least one sensor device according to the invention.
