    sensor element towards the surface of the burner lid. Here, a translucent infrared material could close the groove and / or the passage flush.
    Alternatively or additionally, the groove and / or the passage may be filled with a translucent material for the infrared above the upper side of the infrared sensor device. In this way, the infrared sensor device can be protected against mechanical, chemical and / or electrical damage.
    The translucent material for the infrared presents a degree of transmission for electromagnetic waves in the range of infrared wavelengths of more than 0.5, preferably, more than 0.7 and, more preferably, more than 0 , 85. The translucent material for the infrared can comprise, for example, ionic monocrystals (for example, sodium chloride), semiconductors in monocrystalline or polycrystalline form (for example, germanium or silicon), polycrystalline compounds II-VI (for example, zinc sulphide or zinc selenide), chalcogenide glasses and / or plastic materials based on polymethylmethacrylate.
    According to another embodiment, the gas burner has several gas outlet openings to generate flames. The flames form a flame area during normal operation of the gas burner, and the gas outlet openings are arranged such that an area detected by the infrared sensor device is outside the flame area. Preferably, the gas outlet openings and the infrared sensor device are arranged such that the detected area is outside the flame area at the degree of the maximum heating power of the gas burner.
    According to another embodiment, the infrared sensor device is disposed within a support surface of the burner cap on the burner base.
    A gas cooking point with the gas burner may have a cover plate, on or next to which the gas burner is positioned. The cover plate may have an opening in the gas burner position through which a flammable gas can be supplied to the gas burner.
    The burner base may have a cylindrical shape with an annular side surface and be made, for example, as a hollow cylinder, ring and / or crown. The hollow space located in the central area of the burner base, which is surrounded by the side surface, can be configured as a mixing chamber for mixing gas with air.

    According to another embodiment, the light conductor crosses the burner base at least partially. Here, the sensor element is disposed outside the gas burner.
    The sensor element may be positioned under a cooking field plate on which the gas cooking point is arranged.
    According to another embodiment, the gas cooking point is coupled with a control unit to activate the gas cooking point. By means of the control unit, the heating power of the gas cooking point can be adjustable and / or modifiable. Also, the sensor element could be coupled with the control unit and / or integrated in the control unit.
    According to another embodiment, the light conductor comprises polymeric optical fibers and / or glass fibers.
    Polymeric optical fibers and glass fibers may be appropriate for transporting light in the range of infrared wavelengths. These fibers can reduce the complexity of manufacturing and / or the manufacturing costs of the light conductor.
    According to another embodiment, the gas cooking point further comprises a pot holder comprising a frame and several wings that are directed inwards from the frame. The sensor device is arranged under one of the wings.
    In particular, the upper side of the wings can be used as support sections for the cooking product container and can distance it from the gas burner. A wing between a gas outlet opening and the cooking product container can be heated by the flame and expel heat to the environment, in particular the frame, which could cause a loss of energy. Therefore, it can be energy advantageous that no gas outlet opening is arranged under the wings. Here, the sensor device could be arranged under one of the wings, so that the detection area would be outside the flame area. In this way, it is possible to avoid disturbing the detection of the thermal radiation that the infrared sensor device makes.
    Also, a cooking field arrangement is proposed comprising one or more of the gas cooking points mentioned above or below.
    A cooking field arrangement of this type can adapt the heating power of the gas cooking point according to the thermal radiation detected, which can be converted into the temperature of the cooking product container. Thus


    it can ensure that the cooking product container is not overheated, that is, that the cooking product container is not heated to a temperature above a predetermined limit value.
    According to another embodiment, the cooking field arrangement further comprises a control unit. The infrared sensor device of the gas cooking point is configured to generate sensor signals depending on the thermal radiation detected and transmit them to the control unit.
    According to another embodiment, the control unit directs the heating power of the gas cooking point depending on the sensor signals.
    The control unit can be configured to direct the heating power of each of the gas cooking points according to the thermal radiation detected. Here, the flow rate of the flammable gas-air mixture directed towards the respective gas burners can be directed in particular. The sensor signals of the infrared sensor device can be transmitted, for example, electrically, magnetically, mechanically, acoustically and / or optically.
    Also, the control unit can be coupled with the sensor element of the infrared sensor device, housing and / or understanding it. Accordingly, the light conductor of the infrared sensor device can supply the detected thermal radiation to the control unit, and the control unit can generate the corresponding sensor signals.
    Other configurations and advantageous aspects of the invention are the subject of the secondary claims, as well as the embodiments of the invention described below. Next, the invention is explained in more detail by means of preferred embodiments, with reference to the attached figures.

Coaxially to step 8f another step 8e is performed on the burner cover 4, which houses a sensor element 5e. The sensor element 5e together with the light conductor 5f forms an infrared sensor device 5, which is suitable for detecting the IR thermal radiation that is emitted from the bottom side 6s of the cooking product container 6. Therefore, the device infrared sensor 5e, 5f crosses the burner base 3 and the burner cover 4.
    Figures 3A to 3E show embodiments of a step 8e, 8f in a partial view III of Figure 2.
    In Fig. 3A, a first step 8e is configured in the burner cover 4. The first step 8e has a circular cross-section, and is configured to accommodate a sensor element 5e. The second step 8f, which has a circular cross-section with a smaller diameter than the first step 8e, is made in the burner base 3, and houses the light conductor 5e, which is connected to the sensor element 5e.
    The sensor element 5e can at least partially fill the first step 8e. Figure 3B shows a sensor element 5e, which completely fills the first step 8e of the burner cover 4. Here, the upper side 5s of the sensor element 5e is arranged flush with the upper side of the burner cover 4s.
