    Cooking field device. The invention relates to a cooking field device, in particular, to an induction cooking field device, with one or more contact pressure units (10a; 10b) having one or more elastic elements (12a; 12b) ), and which are intended to press one or more heating units (14a; 14b) against a cooking field plate (16a; 16b). In order to improve the contact pressure of the heating units against the cooking field plate, it is proposed that the contact pressure unit (s) (10a; 10b) have one or more bushing units (18a; 18b) that in a mounted state they envelop the elastic elements (12a; 12b) to a large extent or completely.

    COOKING FIELD DEVICE
    DESCRIPTION
    The invention refers to a cooking field device according to the preamble of claim 1.
    From the state of the art, induction cooking fields having a cooking field plate and a spring-like elastic element are known, which is intended to indirectly press an inductor against a cooking field plate .
    The invention solves the technical problem of providing a generic cooking field device with improved properties in relation to the contact pressure of the heating units against the cooking field plate. According to the invention, this technical problem is solved by the features of claim 1, while advantageous embodiments and improvements of the invention can be extracted from the secondary claims.
    The invention refers to a cooking field device, in particular, to an induction cooking field device, with one or more contact pressure units having one or more elastic elements, and which are provided to press a or several heating units indirectly against a cooking field plate, where the contact pressure unit (s) have one or more bushing units that in a mounted state wrap and / or surround the elastic element (s) largely or completely and, preferably, completely.
    The term "cooking field device" includes the concept of one or more parts, namely, a construction subgroup, of a cooking field, preferably, of an induction cooking field. The cooking field device may also comprise the entire cooking field, preferably the entire induction cooking field. The cooking field device may have the heating units and / or the cooking field plate, which is preferably composed of glass and / or glass ceramic in part or in whole, preferably, in large part or in its entirety. whole and, more preferably, completely. The expression "in large or in whole" includes the concept of 70% or more, advantageously, 80% or more, preferably, 90% or more and, more preferably, 95% or plus. Heating units

    It has a length of approximately 55 cm, a width of approximately 50 cm, and a constant material thickness of approximately 1.5 mm.
    The cooking field device also has several heating units 14a, in this case, four heating units 14a. Each heating unit 14a is associated with one of the heating zones 28a. The heating units 14a are made approximately or completely identical to each other. In addition, the heating units 14a are arranged in the interior space 30a, between the cooking field plate 16a, namely, an inner side of the cooking field plate 16a, and the clamping unit 34a. The heating units 14a are fixed on the clamping unit 34a. Each of the heating units 14a has here a support element 36a and a heating element 38a. The heating elements 38a are made as inductors, and are intended to generate a high frequency magnetic field in order to heat a cooking battery. Each heating element 38a is fixed on one of the support elements 36a. In the present case, the support elements 36a are made raised 2 mm in the direction of the cooking field plate 16a compared to the heating elements 38a. Alternatively, it is also conceived that a heating unit comprises several support elements, preferably two or more and / or three or more support elements, and / or several heating elements, preferably two or more and / or three or More heating elements. In addition, it is conceived that the heating elements are made higher compared to the support elements and / or have the same height. Alternatively, it is also conceived that a cooking field device has a heating matrix, for example, with 4 x 4 heating elements.
    Also, the cooking field device has several contact pressure units 10a, in the present case, nine contact pressure units 10a, although a cooking field device may also alternatively have another number of contact pressure units such as , for example, two or more, four or more, six or more, eight or more and / or ten or more contact pressure units. The contact pressure units 10a are made identically with each other. In addition, the contact pressure units 10a are disposed between the housing unit 32a and the clamping unit 14a, in particular, they are fixed by joining material to the housing unit 32a and are in contact with the clamping unit 34a. Here, each of the contact pressure units 10a has a contact surface with the clamping unit 34a. The contact pressure units 10a are provided to press the clamping unit 34a in the direction of the cooking field plate 16a, thus pressing the units of

    partially or completely to the contact pressure element 22a in the perimeter direction. In addition, the contact pressure element 22a closes the opening of the housing area 40a. Here, the contact pressure element 22a is housed in a mobile manner. In the present case, the bushing housing 20a and the contact pressure element 22a are connected to each other by a coupling in a direction parallel to the contact pressure force. Thus, the trailing connection elements 54a of the contact pressure element 22a grab behind the trailing connection elements 48a of the bushing housing 20a.
    Also, the elastic element 12a is completely arranged in the housing area 40a, presenting a pre-tension. In the assembled state, the elastic element 12a has a longitudinal extension of 13 mm. In the present case, the bushing housing 20a completely envelops the elastic element 12a in the perimeter direction, and the base of the bushing housing 44a and the contact pressure element 22a completely envelop the longitudinal sides of the elastic element 12a, by what the bushing unit 18a wraps around the elastic element 12a completely, which in turn wraps the rod 52a of the contact pressure element 22a and the bushing housing mandrel 46a of the bushing housing 20a. The mandrel of the sleeve housing 46a and / or the stem 52a are provided to prevent the elastic element 12a from bending and / or to center the elastic element 12a.
    In the present case, the contact pressure element 22a can move along a path of approximately 8 mm in the direction parallel to the contact pressure force and / or in the direction of the heating unit 14a and / or the cooking field plate 16a. The movement of the contact pressure element 22a is limited by the trailing connection elements 54a and the trailing connection elements 48a, as well as by the mandrel of the sleeve housing 46a and / or the minimum longitudinal extension of elastic element 12a.
    Another embodiment of the invention is shown in Figures 6 to 8. The following description and drawing are essentially limited to the differences between the embodiments, 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 embodiment of figures 1 to
    5. For the differentiation of the examples of embodiment, the letter "a" has been postponed to the reference symbols of the embodiment example of Figures 1 to 5 and, in the example of embodiment of Figures 6 to 8, the letter "A" has been replaced by the letter "b".
