    GAS COOKING POINT AND FIELD PROVISION OF
    COOKING
    DESCRIPTION
    The present invention refers to a gas cooking point and a cooking field arrangement.
    A gas cooking point may have a gas burner and a gas valve that is configured to regulate the flow of combustible gas directed towards the gas burner from a main gas conduit of the gas cooking point. The gas valve can be operated by means of a control button installed in a torsion-resistant manner next to a drive axis of the gas valve. A sealing device can be provided between the control button and a cover element of the gas cooking point. International patent application WO 2006/128790 A1 describes such a sealing device. When the actuation button moves axially in the direction of the cover element, the sealing device deforms elastically.
    Given this background, the present invention solves the technical problem of providing an improved gas cooking point.
    Therefore, a gas cooking point with a gas valve is proposed, with a control element for actuating the torsion-resistant gas valve connected with a gas valve drive shaft, and with a device sealer The sealing device is disposed between the control element and a gas cooking point covering element, where the sealing device comprises a first sealing element that is connected with the covering element and a second sealing element that is connected with the element control, where the first sealing element is plugged into the second sealing element, and where the second sealing element moves relative to the first sealing element when the control element is turned.
    When the first sealing element is plugged into the second sealing element, it is safely prevented that a liquid or product can pass between the control element and the sealing element, or between the control element and the sealing device. cooking reaching inside the gas cooking point. The control element may comprise the sealing device. The cover element may be part of a
    Gas cooking point housing, a cooking range arrangement, or a gas cooker.
    According to a form of realization, the first sealing element and the second sealing element are elastically deformable.
    5 Specifically, the sealing elements are elastically deformable as a spring. In an alternative embodiment, it is also possible that only the first sealing element is elastically deformable. Preferably, the sealing elements are made of an elastically deformable plastic material.
    According to another embodiment, the first sealing element is plugged into the second sealing element such that the first sealing element touches the second sealing element perimetrically.
    Preferably, the first sealing element is pressed into the second sealing element, so that the inside diameter of the second sealing element is enlarged and / or the outside diameter of the first sealing element is compressed. In this way, a secure seal is guaranteed at all times.
    According to another embodiment, the first sealing element and the second sealing element are made of a silicone material.
    Alternatively, any other elastically deformable plastic material such as a polyurethane material can be used.
    20 According to another embodiment, the first sealing element has a circular annular groove, in which a circulating edge of an opening provided in the cover element fits.
    In this way, liquid is prevented from penetrating between the sealing element and the opening. Preferably, the circulating edge is pressed into the annular groove, so that there is no air gap between the sealing element and the circulating edge.
    According to another embodiment, the first sealing element has a first discoidal support section, which is supported by the cover element on the inner side.
    In this way, it is ensured that the first sealing element is securely attached next to the cover element.

    According to another form of realization, the first sealing element has a second section of discoidal support, which rests on the cover element on the outer side.
    In this way, it is safely prevented that liquid or cooking product will penetrate through the opening of the cover element. Preferably, the cover element is positioned between the support sections.
    According to another form of realization, the diameter of the first support section is larger than the diameter of the second support section.
    In this way, the assembly of the first sealing element next to the cover element is simplified.
    According to another embodiment, the first sealing element is axially compressible along the drive shaft.
    In particular, the first sealing element is axially compressible along a central or symmetrical axis of the first sealing element and / or of the second sealing element, in particular, in a compression direction, which is oriented along the axis drive in direction of the cover element. When the control element moves in the direction of the cover element, the first sealing element is axially compressible. Preferably, the first sealing element has a first tubular section or base section, an elastic section that protrudes radially from the base section, and a second tubular section. The base section is linked to the second section through the elastic section. When the first sealing element is compressed, the elastic section can be deformed so that the base section moves in the direction of the second section. The base section can be moved so that it is arranged within the second section. Preferably, the diameter of the base section is smaller than the diameter of the second section.
    According to another form of realization, the second sealing element is injected or molded next to the control element.
    Preferably, the second sealing element has an annular geometry, and is injected or molded together with an actuation section of the control element. As an example, the drive section can be an injection molded plastic part composed of two components. In this way, the second sealing element can be manufactured in large quantities economically.
    According to another form of realization, the first sealing element and the second sealing element radially seal with respect to each other.
    In this way, tightness is guaranteed at all times if there is a movement of the second sealing element relative to the first sealing element. 5 Additionally, the first sealing element and the second sealing element can seal axially with respect to each other.
    Likewise, a cooking field arrangement with a gas cooking point of the exposed type is proposed.
    The cooking field arrangement may be part of a domestic appliance, for example, 10 of a gas cooker.
    Other possible implementations of the gas cooking point and / or the cooking field arrangement also comprise explicitly not mentioned combinations of features or forms of realization described above, or below, in relation to the realization examples. Here, the person skilled in the art will also add to the respective basic form of the gas cooking point and / or the disposition of the cooking field particular aspects such as improvements or complements.

    injection molded. In addition, the control element 11 comprises a drive section 14 which is connected to the drive shaft 10 in a torsionally resistant manner. By way of example, the drive section 14 is connected to the drive shaft 10 in a torsion-resistant manner by means of a tongue and groove joint. In turn, the control section 13 is torsionally bonded to the drive section 14. By way of example, the control section 13 is connected by quick engagement with the drive section 14.
    The sealing device 12 comprises a first sealing element 15, which is connected to the cover element 8, and a second sealing element 16, which is connected to the control element 11, in particular, to the operating section 14. Such and as shown in Figure 3, the first sealing element 15 is plugged into the second sealing element 16. When the control element 11 is turned, the second sealing element 16 moves relative to the first sealing element 15. The first sealing element 15 is disposed next to the cover element 8 in a torsion-resistant manner, and the second sealing element 16 is fixed to the actuation section 14.
    Figure 4 shows the drive section 14 and the sealing device 12 in another schematic section view. Preferably, the first sealing element 15 is plugged into the second sealing element 16 such that the first sealing element 15 touches the second sealing element 16 perimetrically as the two sealing elements 15, 16 rotate relative to each other. When the control element 11 is turned, the second sealing element 16 slides next to the first sealing element 15. Preferably, the outer diameter d15 of the first sealing element 15 is slightly larger than the inner diameter d16 of the second sealing element 16. Of this way, it is guaranteed at all times that the sealing elements 15, 16 are sealed radially with respect to each other. The first sealing element 15 is pressed into the second sealing element 16. Preferably, the first sealing element 15 and the second sealing element 16 are elastically deformable, and are made of a silicone material. Preferably, the sealing elements 15, 16 are made rotationally symmetrically with respect to a symmetrical or central axis 17.
    Figure 5 shows the drive section 14 with the second sealing element 16 in view of a schematic section.

    central 17. In addition, the second sealing element 16 is preferably fixedly connected with the control element 11, in particular, with the operating section 14. By way of example, the second sealing element 16 may be injected or molded together with the drive section 14, which can be, for example, an injection molded part composed of two components. The second sealing element 16 has a rectangular notch 19 next to an upper side 18 which forms a contact area of the second sealing element 16 with the operating section 14. The contact area is in the form of "L".
    Figure 6 shows the first sealing element 15 in view of schematic section. The first sealing element 15 is made symmetrically rotationally with respect to the central axis 17, and is elastically deformable. Preferably, an upper side 20 of the first sealing element 15 is provided with a bevel 21, so that the action consisting of plugging or inserting the first sealing element 15 into the second sealing element 16. is facilitated. The first sealing element 15 has a first tubular section or base section 22, which is reinforced on its upper side 20 with a circulating reinforcement rib 23 protruding in the direction of the central axis 17. The base section 22 is transformed into an elastic section 24 arranged horizontally and protruding radially from the base section 22. The elastic section 24 is followed by a second tubular section 25. The first sealing element 15 is compressible in a compression direction S along the drive shaft 10, that is, in the direction of the central axis 17. When the first sealing element 15 is compressed, the elastic section 24 is deformed, so that the base section 22 moves in the direction of the section 25, it can be moved in such a way that it is arranged inside the section 25. When the control element 11 moves along the central axis 17, that is, in the compression direction S, the first sealing element 15 is compressed.
    In addition, the first sealing element 15 has a circular annular notch 26 in which a circulating edge of the opening 9 provided in the covering element 8 fits. For this, the first sealing element 15 has a first supporting section 27, the disk which rests on the cover element 8 on the inner side. The first support section 27 has an outside diameter d27. Likewise, the first sealing element 15 has a second discoidal support section 28, which rests on the cover element 8 on the outer side. The second support section 28 is connected to section 25, and is connected to the first support section 27 through a circulating wall 29. The diameter d27 of the first support section 27 is larger than the diameter d28 of the second support
    support section 28. By means of support sections 27, 28, the penetration of cooking product or liquid through the opening 9 is prevented.
    The first sealing element 15 and the second sealing element 16 seal radially with respect to each other. In particular, the first sealing element 15 is plugged into the second sealing element 16 such that the diameter d16 of the second sealing element 16 is slightly enlarged and / or the diameter d15 of the first sealing element 15 is compressed. In this way, it is ensured that the first sealing element 15 exerts at all times a radial contact pressure against the second sealing element 16, thus avoiding in a secure manner that liquid or dirt penetrates through the opening 9.
