    Figure 1 shows in schematic top view a domestic appliance 20a configured as an induction cooking field, which comprises a domestic appliance device having a substrate 10a, of which an outer side 24a is shown in Figure 1. In this case, the substrate 10a is an induction cooking plate, consisting of ceramic hob. Likewise, the substrate 10a is made at least essentially as a plate and in the form of a parallelepiped, and has a length of approximately 55 cm, a width of approximately 50 cm, and a constant thickness of 4 mm. The substrate 10a comprises four heating zones 22a.
    In addition, the domestic appliance device has several sensor elements 12a (see also Figure 2), which are arranged under the substrate 10a. In the present case, exactly one sensor element 12a is assigned to each heating zone 22a, and each of the sensor elements 12a is arranged directly in the zone of one of the heating zones 22a. The sensor elements 12a are identical to each other. As an alternative, it is also conceived that a sensor element is arranged at any other point of a substrate. Also, several sensor elements could be associated with one or more heating zones.
    Figure 2 shows an inner side 26a of the substrate 10a, located opposite the outer side 24a, and one of the sensor elements 12a, whereby the following description is limited to one of the sensor elements 12a, although it can be applied to the other elements 12a sensors.
    The sensor element 12a is applied on the inner side 26a of the substrate 10a by an inkjet printing process. Here, the sensor element 12a is made of an electrically conductive ink. In the present case, the sensor element 12a is basically or completely composed of zinc oxide doped with silver. The sensor element 12a is made approximately or exactly in the form of a parallelepiped and, in the present case, has a length of approximately 3 mm, a width of 3 mm

    approximately, and at least essentially constant thickness of approximately 100 pm. Alternatively, a sensor element can also have any other shape, such as round and / or other desired dimensions.
    Also, the sensor element 12a is made as a temperature sensor, in the present case, as an NTC thermistor. The sensor element 12a is configured as an NTC resistor, so it has a negative temperature coefficient. At a temperature of 25 ° C, the sensor element 12a has a nominal resistance of approximately 103 Q. At least in a temperature range between 20 ° C and 250 ° C, the sensor element 12a exhibits an exponential thermal behavior. In the present case, the sensor element 12a exhibits an exponentially increasing conductivity with increasing temperature, presenting at a temperature of 250 ° C a conductivity approximately 10 times greater than at a temperature of 20 ° C. The sensor element 12a is provided to modify its conductivity and / or its electrical resistance depending on the temperature of the heating zone 22a. Alternatively, a sensor element such as PTC thermistor is also conceived.
    The domestic appliance device also has a contacting unit 14a, which is applied on the inner side 26a of the substrate 10a by means of a printing procedure, in the present case, by an inkjet printing procedure. The contacting unit 14a is made of another electrically conductive ink and, in the present case, is basically or completely composed of an ink doped with copper. The contacting unit 14a comprises two contacting elements 16a, 18a, which are identical to each other. In the present case, the contacting elements 16a, 18a are made as electrodes and / or conductive tracks. The contacting elements 16a, 18a have a transverse extension of approximately 1.5 mm and an at least essentially constant thickness of approximately 100 pm. Also, the contacting elements 16a, 18a are in electrical contact with the sensor element 12a and, in the present case, are provided to connect the sensor element 12a directly with a measuring unit (not shown). Alternatively, it is also conceived that one or more contact elements are provided to connect a sensor element with an evaluation unit and / or with a measurement unit indirectly. Likewise, a contacting unit may also present any other number of contacting elements, and the contacting elements may have any other form and / or other dimensions that are desired. In addition, it is conceived that the contact

    Electrical with one or more sensor elements is carried out through one or more electrical cables.
    The procedure for manufacturing the domestic appliance device is basically done in two steps.
    In a first step of the process, the contacting unit 14a is produced, for which, the other electrically conductive ink, in particular, the ink doped with copper, is applied by an inkjet printing process on the substrate 10a, specifically, on the inner side 26a. Here, the other electrically conductive ink is applied on the substrate 10a at a temperature of about 21 ° C. In this state, the other electrically conductive ink is essential or totally liquid. In the present case, the other electrically conductive ink is applied on the substrate 10a by an overpressure through an injector of a printhead (not shown). Also, the other electrically conductive ink is provided with a point of separation, which has a length that corresponds approximately or exactly with the sensor element 12a. In the cured state, the two ends of the separation point form contacts for the sensor element 12a.
    The other electrically conductive ink has copper particles, which are intended to increase the conductivity of the other electrically conductive ink and have a size of approximately 0.5 pm. The other electrically conductive ink has a conductivity of approximately 40 • 106 S / m.
    Then, the other electrically conductive ink is cured, in the present case, in a reflux oven, at a temperature of 200 ° C for a time of 8 min. During the curing phase, a solvent evaporates from the other electrically conductive ink. In the cured state, the other electrically conductive ink forms the contacting elements 16a, 18a.
    In the second step of the process, the sensor element 12a is produced, for which, the electrically conductive ink, in particular, the zinc oxide doped with silver, is applied on the substrate 10a, in particular, on the inner side 26a, by an analogous inkjet printing procedure to that of the first step of the procedure. Here, electrically conductive ink is applied on the substrate 10a at a temperature of approximately 21 ° C, being arranged between the contacting elements 16a, 18a. In addition, electrically conductive ink has silver particles, which are intended to increase the conductivity of electrically conductive ink and
    5
    10

    30
    They have a size of approximately 0.1 pm. Then, the electrically conductive ink is cured analogously to the first step of the process. In the cured state, the electrically conductive ink forms the sensor element 12a.
    As an alternative, it is also conceived that in a first step of the procedure a sensor element is produced and, in a second step of the procedure, a contact unit. In addition, it is conceived that a sensor element and a contacting unit are applied on a substrate in the same process step and, preferably, simultaneously, and that they be cured together.
    Another example of realization of the invention is shown in Figures 3 to 5. The following description and drawing are essentially limited to the differences between the examples of realization, where, in relation to components indicated in the same way, in particular, in terms of components with the same reference symbols, it can also be basically referred to the drawing and / or the description of the other realization example of Figures 1 and 2. For the differentiation of the realization examples, the letter "a" has been postponed to the reference symbols of the realization example of Figures 1 and 2 and In the example of realization of Figures 3 to 5, the letter "a" has been replaced by the letter "b".
    Figures 3 to 5 show another domestic appliance device with a substrate 10b made as an induction cooking plate. However, in this case the contacting unit 14b has two contacting elements 16b, 18b made as interdigital electrodes.
    Figure 3 shows the domestic appliance device in an incomplete state, in particular, in a first step of the process, in which only the contacting elements 16b, 18b are arranged on the substrate 10b, in particular on the side interior 26b of this. The contacting elements 16b, 18b are made in the form of a comb and / or in the form of fingers, and are interdigital electrodes that engage each other. Also, the contacting elements 16b, 18b are electrically conductively connected with other contacting elements (not shown) made as conductive tracks, which are directly connected with a measuring unit (not shown).
    Figures 4 and 5 show the domestic appliance device in a completely manufactured state. A sensor element 12b is applied on the inner side 26b of the substrate 10b by an inkjet printing process. Likewise, the sensor element 12b is arranged above the contacting elements 16b, 18b, whereby
    these are arranged at least in part between the substrate 10b, specifically, the inner side 26b, and the sensor element 12b. In this way, the measurement sensitivity can be improved. However, as an alternative, it is also conceived that a sensor element is disposed between a substrate, in particular an inner side of the substrate, and a contacting element, in particular, an interdigital electrode.
