    BACKGROUND OF THE INVENTION The invention relates to a bearing device for an elongate heating body of a household appliance, with a body of a household appliance. bearing which has a hollow space, which is limited by a side wall of the bearing body, and a through hole is formed in the side wall, through which the heating body extends to the mounted state. In addition, the invention relates to an arrangement comprising a bearing device and a heating body.
    Heating bodies, which are installed for example as a grill heating element in a cooking chamber of a grilling appliance or in a fryer, are well known in the state of the art. Figure 1 is a perspective representation showing a portion of such a cooking apparatus. A first heating element part 2 and a second heating element part 3 are mounted on a wall 1 of the cooking appliance by means of a bearing device 4. The two heating element parts 2 and 3 are the end pieces of a single tubular heating body. The bearing device 4 comprises a bearing body 5 which has a hollow space in which the heating element parts 2 and 3 extend. The heating element piece 3 is fixed inside the bearing body 5 by means of screws 6 and 7. Similarly, the mounting is the same for the heating element part 2. The axial movement of the heating element parts in the bearing body is thus prevented by additional parts, the screws. However, for fixing these screws, additional threaded passages must be made in specific parts of the heating body. In addition to increased component costs, assembly is expensive and difficult. Since the components are often placed in inaccessible places, it is relatively difficult to access them to place the screws and in particular also to correctly position the bearing housing and the heating element parts relative to the housing. other, in order to be able to introduce the screws 6 and 7 precisely and precisely.
    The object of the present invention is to provide a bearing device for an arrangement comprising such a bearing device and a heating body, which comprises fewer parts and which allows a less expensive and simpler assembly.
    This object is achieved by a bearing device, which has the features of claim 1, by an arrangement which has the features of claim 7, and by a method which has the features of claim 15.
    A bearing device according to the invention for an elongate heating body of a household appliance comprises a bearing body having a hollow space which is bounded by a side wall of the bearing body and a through hole is formed in the housing. side wall, through which the heating body extends to the mounted state. A stop member reducing the inner dimension of the hole is disposed on the inner side of the hole. Such a configuration makes it possible to guarantee an embodiment of the bearing device with a smaller number of parts and it further ensures that the mounting is simpler and that the assembly of the bearing device with the heating body is nevertheless mechanically stable.
    Preferably, the stop member is a circle segment. This specific shape allows, with a single element, the effective stop and the passage of the heating body during the introduction into the hole and during the corresponding positioning, and allows on the other hand to ensure particularly simple handling of this introduction itself in narrow areas and little visible during assembly.
    Preferably, the hole has a shape that has no corners, and is particularly circular. Precisely in combination with the realization of the stop element in the form of a segment of a circle, this constitutes a particularly advantageous embodiment in view of a possibility of simple, quick and easy assembly for the user, and of on the other hand a mechanically stable setting of holding positions of the bearing body and the heating body.
    Preferably, the bearing body is made in one piece. It is constituted in particular by a molded metal part, for example a thin zinc alloy, such as Zamak. It allows a simple and economical manufacture. In addition, the fact that it is in one piece ensures a configuration that is mechanically stable and reduces the number of parts. It is thus possible to avoid undesirable tolerances during assembly, which exist in the case of a multi-piece bearing body.
    Preferably, the stop member has a thickness, which is less than the thickness of the side wall. Even under these conditions, a particularly compact embodiment can be obtained in the direction of the longitudinal axis of the bearing body, because other components can still be accommodated in the hole, which has a greater thickness, and that these, especially if considered also in the direction of the axis A, can be positioned in series with the stop element.
    Preferably, the stop member is disposed in the hole in an inwardly displaced position from the outer side of the side wall. By this positioning pushed inwardly, it is possible furthermore to achieve a complete closure of the hole by means of a piece still laid outwardly on the stop element and to obtain this result by also greatly reducing the mounting space.
    In addition, the invention relates to an arrangement comprising a bearing device according to the invention or an advantageous configuration thereof, and an elongated heating body, which can be mounted in a fixed position in the bearing body. Such an arrangement ensures a simple and yet mechanically stable connection between the bearing body and the heating body. In addition, this assembly does not require other additional parts, such as screws or the like for example.
    It is particularly preferable that, to reach the fixed end position, the heating body is introduced through the hole in the bearing housing and is positioned in an insertion position and that the final position is adjusted by a relative movement, in particular a rotation about the longitudinal axis of the bearing body by an angle greater than or equal to 10 °, in particular 180 °, between the heating body and the bearing body, from the insertion position. Precisely in the embodiment of the bearing body with the stop member, thus provides a construction which ensures the introduction of the heating body into the bearing body through the hole only in a position quite specific to the body bearing and the heating body relative to each other. The insertion position between the bearing body and the heating body can thus only be achieved in a very specific manner. This position is not yet the fixed end position. To achieve this, a relative movement between the two components is therefore required from this insertion position, which makes it possible to reach the final position and which thus places the two components in a fixed position.
    In this final position, no extraction of the heating body from the bearing body through the hole is possible because this is prevented in this position by means of the stop element.
    Preferably, an adjustment member is disposed on an elongated heating element of the heating body, which has a shape which, joined to the stop member, has the shape of the hole. An embodiment is thus obtained in which the shapes of the adjustment member and the stop member are configured in such a way that they correspond to the shape of the hole. The adjustment element constitutes the missing part for the realization of the circular hole, in particular when the stop element is a segment of a circle.
    Such a shape of the adjusting member and the stop member ensures that the introduction of the heating body into the bearing body is only guaranteed in a specific position of the two components with respect to each other. other, that it is thus possible to reach the insertion position and furthermore to reach the fixed end position by a rotation of the components relative to each other.
    Preferably, the adjusting element is arranged on the heating element in such a way that the introduction of the heating element into the hollow space of the bearing body to reach the insertion position is guaranteed and that the element The fit can be inserted into the hollow space from outside the bearing body along the stop element.
    In particular, the adjustment element is arranged on the heating element in such a way that, in the fixed final position, the adjustment element and the stop element, considered in the direction of the longitudinal axis of the bearing body, are arranged one behind the other and with overlap. This means that, practically upon introduction of the heating element into the bearing body, the adjustment member is guided in a specific orientation along the stop member and that the insertion position is thereafter, and rotation occurs as a result of the relative movement between the bearing body and the heating element, so that the adjustment member and the stop member, considered in the direction of the longitudinal axis of the bearing body, can no longer be moved along one another. The displacement of the heating element outwardly through the hole is thereby prevented.
    Preferably, a closure element, which has the shape of the hole, is disposed on the heating element, at a distance from the adjustment element, and the hole is closed by the closure element, in the final position. fixed. Such an embodiment makes it possible, in combination with the adjustment element, to form a stop during the introduction, in such a way that the introduction can not be carried out beyond a determined path in the direction of the axis of the bearing body. In addition, such an embodiment allows that, in the fixed end position, the heating element can no longer be moved in both directions in the direction of the longitudinal axis of the bearing body. In this final position, the stop member is substantially locked on one side by the closure member and on the other side by the adjustment member. In particular, the distance corresponds to the thickness of the stop element, which makes it possible to obtain the advantageous embodiment precisely explained above.
    Preferably, the thickness of the closure member corresponds to the thickness of the side wall, minus the thickness of the stop member. Such an embodiment makes it possible to position the stop element flush with the inner side of the side wall. Likewise, a position of the flush closure element on the outer side of the side wall is possible. Preferably, the stop member is in contact with each other, in the final position, with the adjustment element and with the closure element applied against it.
    In the final position of the two components with respect to each other and in the assembled state of the arrangement on the appliance, the embodiment is further designed such that a spontaneous release of the Fixed end position is no longer possible.
    In addition, the invention relates to a method for assembling a bearing body of a bearing device for a heating body of a household appliance with a heating body, into which the elongated heating body is introduced into a space. hollow of the bearing body through a hole in a side wall of the bearing body so that it extends on either side of the hole. An insertion position is set and, starting from the insertion position, a fixed end position is set between the heating body and the bearing body. This is achieved by making a relative movement about the longitudinal axis of the bearing body between the bearing housing and the heater from the insertion position and positioning a housing element. the fit formed on the heating body by the relative movement so that, viewed in the direction of the longitudinal axis of the bearing body, it is arranged one behind the other with a stop element made in the hole and in recovery with it.
    Advantageous embodiments of the bearing device according to the invention and / or the arrangement according to the invention should be considered as advantageous embodiments of the method according to the invention. Other features of the invention flow from the claims, figures and description of the figures. The features and combinations of characteristics mentioned above in the context of the description as well as the characteristics and combinations of characteristics mentioned only in the description of the figures and / or in the figures are not applicable only in the combinations indicated respectively. , but also in other combinations or in isolation, without departing from the scope of the invention.
    An exemplary embodiment of the invention will be explained in more detail below with reference to the attached schematic drawings, in which:
    Fig. 1 is a perspective representation of a portion of an arrangement known from the state of the art, which is mounted on the appliance;
    Fig. 2 is a perspective representation of an exemplary embodiment of a bearing body according to the invention for a bearing device;
    Fig. 3 shows an embodiment of a heating body according to the invention; Fig. 4 is a side view of the arrangement showing the insertion position between the bearing body and the heating element; and FIG. 5 is a side view showing the final position between the bearing body and the heating element.
    In the figures, identical or functionally identical elements are designated by the same numerical references.
    Figure 2 shows a bearing body 5 ', which is made in one piece and which shows a piece of metal molded of a thin zinc alloy. The bearing body 5 'also represents at the same time the bearing device, which does not have any other element.
    The bearing body 5 'has a rectangular base shape, which has a hollow space 8. The bearing body 5' is furthermore made in such a way that it tapers outwards from its basic shape. rectangular. For this purpose, the bearing body 5 'comprises, if considered in the longitudinal direction of its axis A, side walls 9 and 10 at its opposite ends. There is also a cover wall or cover 11.
    The bearing body 5 'is adapted to receive and support two heating body end pieces of a tubular heater. In addition, the explanation is given only with regard to a hole 12 formed in the side wall 9 and the corresponding possibility of introducing a piece of heating body through the hole 12. A similar explanation is possible for a heater body part, which can be introduced through a corresponding hole in the side wall 10.
    The round hole 12 is made to pass through the side wall 9 and has a circular cross section. It thus presents an interior dimension d7.
    In the hole 12 is formed a stop member 13, which represents a segment of a circle. It thus has the shape of a D. The stop element 13 is formed directly on a wall 14 of the hole. As can be seen, the stop element 13 is shifted inwards in the hole 12 and is thus made at a distance from an outer wall 15 of the side wall 9. In this embodiment, the element with its inner side turned towards the hollow space 8, flush with an inner side 16 of the side wall 9 facing the hollow space 8. Considered in the direction of the longitudinal axis A, the stop element 13 has a thickness d2, and the side wall 9 has on the contrary a thickness dl. This is larger than the thickness d2. As can be seen in the representation of FIG. 2, the stop member 13 is formed in the hole 12 in the inwardly shifted position of a thickness d3 from the outer side 15.
    On its base face, the bearing body 5 'has four fixing lugs 17, 18, 19 and 20. They allow to install the bearing body 5' on a wall of a household appliance, which is intended in particular for grilling or frying.
    In Figure 3, a perspective representation of an embodiment of a heating body 21 can be seen, which can be inserted into and mounted on the bearing body 5 '. The heating body 21 and the bearing body 5 'form a corresponding arrangement.
    The heating body 21 comprises an elongated heating element piece 2 ', which has an outer side 22. On this outer side 22 is formed an adjustment member 23, which is also in the form of a circle segment. The shape of the adjustment member 23 is configured such that it forms a circular disk in association with the stop member 13. The shape and sizing of this compound disk are such that it corresponds to the hole 12. The diameter of the adjusting member 23 is therefore dimensioned to be less than a minimum of the inner dimension d7, such that an introduction of the adjustment member 23 through the hole 12 still possible in this respect.
    Considered in the direction of the longitudinal axis B of the heating body 21, the adjustment element 23 has a thickness d4. In addition, a closure member 24 is formed on the heater member 2 ', away from the adjustment member 23. It is formed as a substantially complete ring around the outer side 22. The diameter of the closure member 24 is sized to be slightly smaller than the internal dimension d7 of the hole 12, so that the closure member 24 can be introduced in precise fit into the hole.
    Considered in the direction of the longitudinal axis B, the closure element 24 has a thickness d6, which corresponds to the thickness d3. In the assembled state, the closing element 24 is thus almost embedded in the hole 12.
    Preferably, the distance d5 between the adjusting member 23 and the closure member 24 is slightly greater than the thickness d2 of the stop member 13. As a result, the stop member 13 may, in the fixed end position, engage in a snug fit between the adjustment member 23 and the closure member 24.
    Figure 4 is a side view schematically showing the arrangement, wherein the heater 21 is in its insertion position 25 in the bearing body 5 '. For this purpose, the heating body 21 is introduced through the hole 12, in particular in such a way that the adjustment element 23 runs in the specific position of the stop element 13 and is introduced into the hollow space 8. FIG. closing member 24 then abuts against the stop member 13. From this insertion position 25, the fixed end position 26 is adjusted which is illustrated in FIG. 5. For this purpose, a relative movement between the bearing body 5 'and the heating body 21, in that the bearing body 5' is rotated by 180 °. In this position, the position is then secured because of the cooperation and the shapes between the hole 12, the stop element 13, the adjustment element 23 and the closure element 24, and prevents in particular a displacement in the direction of the longitudinal axis A. In the assembled position shown in Figure 5, is then carried out on a wall of the appliance, inserting the elements 17 to 20 in corresponding perforated regions .
