Description

Hob {Hob}

The invention relates to a hob comprising a hob plate, heating devices under the hob plate, and a carrier plate supporting the heating devices.

DE 20 2008 016 268 U1 discloses an induction hob comprising heating devices which include a hob plate and which are arranged in an inductor form on the bottom side of the hob plate. The inductor is mounted in a separate carrier tray mounted on the carrier plate in a spring action so as to press the inductor against the bottom side of the hob plate located thereon. The carrier plate also has another functional unit of the induction hob, for example an electrical circuit for driving the inductor or for powering the inductor. One disadvantage of this is the relatively high degree of complexity of the spring arrangement. As an alternative, the inductor may possibly also be mounted directly on the carrier plate by spring action.

The present invention makes it possible to avoid the problems of the prior art and in particular to enable the heating devices to be fastened in a practical and effective manner on the carrier plate and also to securely fasten the heating devices on the bottom side of the hob plate, Of the hob of the kind mentioned in the introduction section.

This problem is solved by a hob having the feature of claim 1. Advantageous and advantageous refinements of the invention are the subject of other claims and will be discussed in more detail below. The expressions of the claims are also included in the detailed description by explicit reference.

A hob is provided having a hob plate, heating devices disposed under the hob plate, and a carrier plate supporting the heating devices. In this case, the carrier plate is intended to cover most of the hob plate or have or cover at least 80% of the surface area of the hob plate. In particular, the hob plate covers the carrier plate with a narrow rim of 3 cm or less in width.

According to the present invention, a carrier carrier is provided on the carrier plate, which is a elongated carrier designed in the form of an elongate carrier or having a elongated shape. The support carrier has a length that spans the carrier plate to a greater extent or at least 80% of its length in one direction or at least 80% of the width of the carrier plate. Advantageously, the support carrier has a length that is at least 90% of the overall length of the carrier plate in this direction or that is at least 90% of the width of the carrier plate. This means that the support carrier can extend approximately from the outer edge to the outer edge of the carrier plate and does not necessarily extend only over the carrier plate. The support carrier is secured to the carrier plate or connected to the carrier plate and is mainly used for the sagging of the carrier plate, especially due to the pressure support from the heating devices which are disposed on the carrier plate and are pressed against the bottom side of the hob plate Sag, and deflection due to temperature effects due to heating during operation. The support carrier may extend below the carrier plate into an area for engagement from below and may extend above the carrier plate into an area for engagement from above. As a result, the support carrier can partially support the carrier plate from below or prevent sagging. In the transition region in which the support carrier transitions from the region for engagement from below to the region for engagement from above, in particular in this region it is also possible to support the carrier plate or to prevent unwanted warping of the carrier plate using a support carrier The support carrier and the carrier plate can be particularly easily connected to each other. It is advantageous that the area for engagement from below and / or the length of the area for engagement from above or the linear extension is at least 10% to 25% of the length of the support carrier. What is possible is not at least a partial direct bearing of the carrier plate by the support carrier, since the surface or plane of the carrier plate penetrates from the bottom to the top or from the top to the bottom. Instead, better variability can also be achieved with the intention that in this manner the regions where the support carrier does not extend and cause no disruption are present both on and below the carrier plate.

In an improvement of the present invention, the support carrier may be in the form of an independent component that is produced separately from the carrier plate. Then, in the final hob, the support carrier may be fastened to the carrier plate or connected to the carrier plate, for example, in a captive manner or in such a way that it can not be released without further destruction. Some connections, such as screw connections, have the advantage that they can be released again, for example for repair work or replacement, but the detention connection for this purpose has the advantage of being more permanent and safer because it is not released during operation. In addition, this type of detent connection can often be established more easily in an automated manner when assembling the hob, i.e., connecting the carrier plate to the support carrier. The possible ways of doing this are described in more detail below.

In another improvement of the invention, the support carrier may be connected to the carrier plate in particular at its both end regions relatively close to each outer end, e.g. a distance of at most 5% or 10% of the length of the support carrier. An additional connection to the carrier plate may be provided at least once in a central region or intermediate region of the support carrier positioned between the end regions. Thus, a three-point fastening can be achieved, which is beneficially beneficial in preventing sagging in the intermediate region of the carrier plate. The connection to each other in the intermediate region of each of the support carrier and the carrier plate may be established at a distance from the ends of the support carrier of at least 20% to 30% of the length of the support carrier, 30% to 45% As an alternative, it is also possible to provide a connection between the support carrier and the carrier plate where the maximum load or deflection of the carrier plate is expected to be precisely the middle area, so that the maximum amount of support is to be provided.

The connection of the support carrier to the carrier plate in the aforementioned intermediate region can be realized by the holding section. This type of retention section may protrude from the support carrier such that elongated retaining slots are formed between the retention section and the remainder of the support carrier, preferably substantially parallel to the support carrier. A section of the carrier plate can engage the retaining slot for connection and retention purposes. This kind of fastening can be released again very easily, for example by moving the support carrier longitudinally or in the longitudinal direction of the retaining slot, but if this movement is restrained by the remainder of the connection between the support carrier and the carrier plate , At least a support connection acting in a direction perpendicular to the carrier plate can be established between the support carrier and the carrier plate without additional work. As an alternative, a retaining section engaging the region of the support carrier may also protrude from the carrier plate.

The retaining slot may extend parallel or at a very flat angle to the plane of the hob plate (advantageously the plane of the carrier plate). This kind of angle may be between 0 [deg.] And 10 [deg.], In particular 0 [deg.]. As an alternative, the angle may be intentionally flat, but not too small. This kind of angle may be between 15 [deg.] And 30 [deg.] With respect to the plane of the hob plate or carrier plate. As a result, the insertion of the section of the carrier plate into the retaining slot can be made more easily with a movement extending obliquely relative to the plane of the hob plate or carrier plate.

In a further refinement of the invention, the support carrier may be fastened to the carrier plate in the form of a connection by means of a material deformation (which corresponds substantially to the previously described detent connection). In this case, a possible alternative to screw connection involves riveting or caulking, in particular the fastening section provided on the support carrier. As an alternative, this type of fastening section can also be bent in the manner of a bending lug or a retaining lug. The riveting can be done first by a separate rivet in addition to the support carrier and the carrier plate. As an alternative, and also in the case of caulking, the fastening section in one part can pass through the plane of the other part, advantageously through the correspondingly formed opening in the other part, and then the connection is released And may be widened or caulked. In this case, a kind of integrated rivet is provided.

In an improvement of the invention, the carrier plate may have an opening, possibly a relatively large opening, at least in the middle region. As is generally known for induction hobs, this kind of opening may be provided in the area under the carrier plate, for example for electrical connection of the heating device. The support carrier may extend at least partially through the aperture and extend through the plane of the carrier plate in the region of the aperture from the area for engagement from below to the area for engagement from above, or vice versa. Thus, no separate opening need be created for the support carrier to pass through the carrier plate. As the support carrier extends through this opening at approximately the center, the opening may also be more conveniently used for practical purposes, such as for example the electrical connection described above. In a further refinement of the invention, it is possible that the rim of said opening engages with said retaining slot of the support carrier as a section of the carrier plate such that the retaining section of the support carrier extends below for connection purposes. This is sufficient to fasten and support the carrier plate in this or intermediate region of the carrier plate.

In another improvement of the invention, it is also possible for the support carrier to have two retention sections each having a retaining slot in the direction of the support carrier, which also extend in opposite directions to each other. The individual rim of the opening can engage the two retaining slots. In this case, the opposing rims of the openings can engage in this kind of retaining slots. Since this can not generally be achieved with the linear movement of the support carrier relative to the carrier plate, the support carrier can be mounted by inserting the retaining section into the opening by a separate retaining slot and by subsequent rotation. During attachment, the support carrier may extend against the aperture to maintain a relatively long area of the aperture, and the spanned length of the aperture may be shorter due to rotation or corresponding mounting movement, The edges of the aperture engage the retaining slots.

In an advantageous refinement of the invention, the support carrier can be fastened or connected to the carrier plate from above in the area for engagement from below. The support carrier can be fastened to the carrier plate from below in the area for engagement from above, i.e. from the other side in both areas. This is particularly advantageous with the above-mentioned caulking section of the support carrier projecting from the support carrier as a fastening section and engaging through a corresponding opening or opening of the carrier plate. In this case, caulking takes place from the other side to fasten the support carrier to the carrier plate or to connect the two parts. This can also be applied to bending over this type of fastening section or when the fastening section itself is used as a riveting arrangement. Threaded connections can also be provided and threads in the bending section of the support carrier are advantageously provided or screws in the form of self-tapping screws are threaded through the carrier plate to the support carrier. The support carrier advantageously has a greater thickness than the carrier plate, so that the thread of the screw can more effectively engage here.

In an improvement of the present invention, in addition to the control function, an operator control device having mainly an operator control element can be arranged in the front region on the carrier plate. Such an operator control element may, for example, have a touch sensor and be pressurized against the bottom side of the hob plate as is well known from the prior art. A heating device, advantageously an inductor for induction hobs, can be arranged in the rear region of the carrier plate which makes up most of the surface area. This heating device covers most, especially at least 70% or even 80% of the surface area of the carrier plate. And, the support carrier advantageously extends below the carrier plate in the front region by an area for engagement from below. The support carrier extends over the carrier plate in the rear region by an area for engagement from above. In this case, the support carrier may extend through between the adjacent heating devices in this rear region. If the support carrier has a narrow design and is somewhat higher, it is advantageously provided to have a certain height for stiffness to deflection, so that it does not require much space, and therefore also between adjacent heating devices Can be easily extended.

In the front region with the operator control device, the support carrier extends below the operator control device disposed on the carrier plate such that the operator control device does not need to be partitioned and need not have any passageways for the support carrier. Therefore, the operator control device can be designed, for example, as an electrical component and in particular as a continuous printed circuit board on which an operator control element or touch sensor is located. The arrangement of the support carrier in the rear region above the carrier plate is advantageous because the area under the carrier plate is not adversely affected by the support carrier in this case. Especially when the hob is designed as an induction hob as described above, it is advantageous because it can be installed under the hob without adversely affecting power electronics and other components that also require cooling air flow.

In principle, the course of the support carrier relative to the hob or carrier plate is irrelevant; What is important is that the support carrier traverses the middle region of the carrier plate intended to be supported as effectively as possible against deflection. As described above with respect to the operator control device and the heating device, the profile of the support carrier in the direction of the hob from the rear to the front is preferred because of the advantages of the area for engagement from above and the area for engagement from below It is possible to divide. Here, in a first improvement of the present invention, a single support carrier may be provided which extends in this case over a central point of the carrier plate and preferably a main point of the surface area to support the carrier plate. It is also believed that this is also advantageous in a hob in which a support carrier can be easily extended between the heating devices, for example by showing a kind of mirror symmetrical division of the heating devices between the left and right sides.

In a second improvement of the invention, three heating devices or three groups of heating devices (of the same size, of any group) may be provided adjacent to one another, mainly in extra-wide hobs . Here, precisely two support carriers extending in parallel in this case from front to back parallel to one another and each extending between adjacent groups of heating devices can be provided. Thus, a carrier plate of this kind of wide hob, which usually has a width of about 90 cm, can also be effectively supported against deflection.

In one example of the present invention, the support carrier may be constructed of a flat material or may be produced from a flat material. The thickness of the flat material may be from 1 mm to 5 mm, advantageously from about 2 mm to 5 mm. This type of relatively thin support carrier can be produced, for example, from metals, especially aluminum. The support carrier may have only one or two support sections that project at right angles to support the carrier plate. The support section ensures that the longitudinal cross-section of the support carrier is upright and that the support carrier is substantially perpendicular to the surface area of the carrier plate or to the carrier plate itself and has a high degree of rigidity with respect to deflection of the carrier plate . When two projecting fastening sections of this kind are provided, it may be particularly advantageous for them to protrude from the support carrier in different directions so as to reliably prevent tilting in both directions. In a possible example of the present invention, these fastening sections may also serve to fasten the support carrier to the carrier plate, e.g., by passing screws or rivets, as generally described above. As an alternative, the fastening sections may have locking lugs at their outer ends that are angled again and extend substantially perpendicular to the surface area of the carrier plate at those portions. These fastening lugs can be used for the above-mentioned riveting, caulking or bending.

A flat support carrier having a profile substantially perpendicular to the surface of the carrier plate may advantageously extend along the carrier plate or be in contact-connect or contact with the carrier plate, especially the edge, in at least a relatively large area of its length. In particular, it is provided in an area for engagement from below to support the carrier plate against deflection at the bottom in a very simple manner.

The height of the support carrier is intended to be from 2 cm to 3 cm, advantageously from 1 cm to 1.5 cm, so that the area of the surface of the carrier plate downward in the region for engagement from above or below, Up to the maximum. Since the hob, in particular the induction hob described above, is intended to be as flat as possible, the overall height must not be increased unnecessarily by the support carrier or increased at all. Therefore, the support carrier must not protrude upwards beyond the heating device in the area for engagement from above, or project beyond the power electronics system for the heating device in the area for engagement from below.

These and further features are apparent from the detailed description and the drawings, as well as the claims, each of the individual features being capable of being implemented in subcombinations of the embodiments of the present invention and in different fields singly or separately, Each of these individual features may be an advantageous and independent protectable embodiment as claimed herein. The subdivision of the present application into individual sections and subheadings does not limit the general effectiveness of the description described below.

Exemplary embodiments of the present invention are schematically illustrated in the drawings and described in greater detail below.

13 is a perspective view of the hob corresponding to Fig.

Figures 1 and 2 are side and plan views, respectively, of a elongated support carrier 11 consisting of a 2 mm to 5 mm thick material, advantageously aluminum or sheet steel. The support carrier 11 has a region 13 for engagement from below on the right side and a region 15 for engagement from above on the left side and an area 15 for engagement from above is approximately three times longer to be. The regions 13 and 15 are connected by a transition region 17 in the form of a double bend. The support carrier 11 has an angled fastening section 19 at the other end in the region 15 for engagement at the right end in the region 13 for the engagement from below and also from above. As shown in FIGS. 3-5, the fastening section 19 may be provided with a screw connection or a rivet connection to the carrier plate for fastening purposes.

The retaining section 21 forming the retaining slot 22 for the remainder of the support carrier 11 is still provided in the middle region so as to protrude downward somewhat to the left of the center of the support carrier 11. [ The retaining slot 22 extends substantially parallel to the support carrier 11 in the region 13 for engagement from below.

The fastening sections 19 are angled in different directions from the support carrier 11 so that a tilting-resistant connection to the carrier plate is possible and, separately, the support carrier 11 is connected to the carrier plate Can be erected at right angles to the plane.

Figures 3-5 show the fastening of the support carrier 11 to the carrier plate 24. The carrier plate 24 is of a generally conventional design as is typical of induction hobs, and is comprised of an aluminum sheet having a thickness of 1 mm to 2 mm. Also as shown primarily in the perspective view, the carrier plate is generally flat in the middle region and folded down at the edge. However, this is known in principle and contributes to stabilization and mounting on the glass frame of the hob. In the intermediate region, the carrier plate 24 has an opening 26 which is also used, for example, to guide the connecting cable of the inductor located on the carrier plate 24 down to the electrical connection. However, this is known.

The support carrier 11 extends below the carrier plate by an area 13 for engagement from below and extends above the carrier plate by an area 15 for engagement from above. In both regions, the support carrier is supported directly on the carrier plate 24, which is mainly important in the support function in the region 13 for engagement from below. The support carrier 11 may extend only from the bottom up through the rectangular opening 26 only or in the through slot 27 as provided herein. This passage slot 27 extends from the right rim of the opening 26. As a result, it is possible, for example, that the support carrier 11 already changes somewhat earlier from the area 13 for engagement from below to the area 15 for engagement from above and extends above the carrier plate 24. [

The support carrier 11 is fastened to the carrier plate 24 by means of a screw 29 having a threading cut into the fastening section 19 of the support carrier 11. The screw 29 for the fastening section 19 of the area 13 for engagement from below is passed from above and is located on the support plate 24 while the area 15 for engagement from above, The screw 29 for the fastening section 19 of the fastening portion 19 extends upwardly from the bottom. A rivet or other interlocking connection element may also be used in place of the screw 29 of the above kind.

An additional fastening in the intermediate region is provided in that the retaining section 21 is engaged under the left rim of the opening 26 so that the rim engages the retaining slot 22. [ As a result, a simple force-fitting fastening is possible that prevents the downward deflection of the intermediate region of the carrier plate 24. [

The illustration of figure 3 shows that the support carrier 11 does not extend completely straight or extends from the free end upwards to the retaining section 21 at the lower edge as in the upper edge of the area 13 for engagement from below, In an upwardly bent manner in the region 15 for engagement from the first and second end portions. Thus, the carrier plate 24 is pre-folded to some extent upward by engagement with the retaining slot 22 at the bottom of the support carrier 11. [ In the case of pressure loading as mentioned in the introduction, the carrier plate can be deflected to some extent and is still flat or horizontal and in particular parallel to the hob plate.

The top view of FIG. 4 shows that a plurality of slots 31 are formed in the carrier plate, which first forms four square fields each for supporting the induction coil later. In some corners of these fields, a round slot 31 is formed. These slots first prevent excessive heating within the carrier plate 15 made of metal. Secondly, the slot can have a favorable effect on the deformation of the carrier plate 24 due to the high temperature.

An operator control device can be fitted later on the front region 25 (on the right side of Fig. 4) of the carrier plate 24. [ This is shown in the sectional view of FIG. 6 by the hob 33 according to the invention, including the hob plate 34 shown using dotted lines, and the operator control device 35 is shown in FIG. Other components of the hob 33, particularly the power electronics 39 and the like, are supported by a carrier tray 37 below the carrier plate 24.

The perspective view of FIG. 5 shows that three elongated lugs bent downward at three edges or rim of opening 26 are provided with the cross-sectional view of FIG. 3 and the plan view of FIG. This contributes to ensuring that the cable is not damaged by the metal edge during the process as the cable can be guided down over the edge or rim and the sharp metal edge is directed downward. However, the edge that is inserted into the retaining slot 22 of the retaining section 21 is intended to be at least linear within the area of the retaining slot 22. Otherwise, insertion is not possible.

7 to 9 show an alternative improvement example of the support carrier 111 having the area 113 for engagement from below and the area 115 for engagement from above on the left side on the right side, Once the region 115 is much longer. A transition region 117 is located between the regions 113 and 115. The basic profile of the support carrier 111 is similar to that of the support carrier 11 of Fig. However, there is no fastening section 19 and a retaining section 21 here. Three spreading lugs 120 are provided instead. In practice, only two spreading lugs are required, and the outermost lugs mainly contribute only to lateral fixation. The outermost lug may also be in the form of a spreading lug, but not necessarily from a functional standpoint. The top view of Figure 8 shows that the fastening sections 19 do not provide good stability against tilting when the support carrier 111 is secured to the carrier plate 124 as compared to the arrangement of Figure 3, . The spreading lugs 120 are configured to engage the spreading lugs 120 as indicated by arrows here, as shown in the enlarged detail view according to FIG. 10 of the fastening of the intermediate spreading lugs 120 to the carrier plate 124. [ Is extended from the lower side through the corresponding recess 128 of the carrier plate, the spreading lug 120 is bent or bumped by a flattened hammer or the like in a manner similar to the rivet device. As a variant, the spreading lugs 120 may be hit by an edge or wedge so that the spreading lugs 120 move away from one another to form a left half that engages the recess 128 To the right half. However, this is principally known to those skilled in the art.

The carrier plate 124 is positioned in the support carrier 111 in the region 113 for engagement from below in the upper portion and is supported by the support carrier so that in the region 113 for engagement from below, The reading lugs 120 and the like are not required.

The cross-sectional view through hob 133 in accordance with FIG. 11 again corresponds substantially to the hob in FIG. 6, wherein there is no hob plate only. In the region shown on the right side of Fig. 11, a elongated operator control device 135 is provided, which area is the front area of the finished hob 133. This is once again shown more clearly in the plan view of FIG. 12 and the perspective view of FIG. As one example, eight induction coils 140 are placed or positioned on a carrier plate 124 in the adjacent region forming the heating zone when the hob is completed. The cable of the induction coil is partially extended through the corresponding opening of the support carrier 111 as power connections 141. [ Control connections are extended in this way. Further, a temperature sensor or the like similarly having a connection portion may be additionally disposed on the induction coil 140. [ In principle, the connection can also be extended as described above.

12 and 13, it can be seen that four additional heat rows are adjacent to one row of four induction heating coils 140 in a wide hob with a typical width of 90 cm and a total of three rows of four induction coils 140 It is easy to imagine whether or not it is provided. In this case, this kind of support carrier 111 is intended to extend between the two rows in each case to support the carrier plate.

The perspective view of Fig. 13 also shows that the support carrier 111 is supported in the front region of the hob 133 or at the carrier plate 124, in order to allow simple design of the operator control device 135, It is clear that it is advantageous when it is extended from the point of view. The construction and installation of the operator control device is considerably simplified in this manner. Also here, automatic support of the carrier plate 124 is provided.

However, there is no space limitation in the region 115 for engagement in the rear region of the hob 133 or from above the support carrier 111, as shown in the cross-sectional view of Fig. Three small spreading lugs 120 do not cause any interruption here, and in this regard reference is made to the above.
