Description

hob {Hob}

The present 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 a hob plate and comprising heating devices arranged in the form of inductors on the bottom side of the hob plate. The inductor is mounted on a separate transport tray mounted on a carrier plate with spring action to press the inductor against the bottom side of a hob plate positioned thereon. The carrier plate also carries another functional unit of the induction hob, eg an electrical circuit for driving or supplying power to the inductor. One disadvantage of this is the relatively high degree of complexity of the spring arrangement. As an alternative, the inductor can possibly also be mounted directly to the carrier plate with spring action.

The present invention makes it possible to avoid the problems of the prior art and in particular to fasten the heating devices on the carrier plate in a practical and effective manner and also preferably provides a secure bearing of the heating devices relative to the bottom side of the hob plate. ) is based on the task of providing a hob of the kind mentioned in the introduction.

This problem is solved by a hob having the features of claim 1 . Advantageous and desirable developments of the present invention are the subject of further claims and will be discussed in more detail below. The language of the claims is also incorporated into the Detailed Description by express reference.

A hob is provided having a hob plate, heating devices disposed below the hob plate, and a carrier plate supporting the heating devices. In this case, the carrier plate covers most of the hob plate or has or is intended to 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 less than 3 cm wide.

According to the invention, a support carrier which is designed in the form of an elongate carrier or which is an elongate carrier having an elongate form is provided on the carrier plate. The support carrier spans the carrier plate to a large extent or at least 80% of its length in one direction or has a length corresponding to at least 80% of the width of the carrier plate. Advantageously, the support carrier has a length corresponding to at least 90% of the width of the carrier plate or lasting at least 90% of the overall length of the carrier plate in this direction. This means that the support carrier can extend approximately from the outer edge to the outer edge of the carrier plate, and not necessarily just over the carrier plate. The support carrier is fastened to or connected to the carrier plate and is mainly due to sagging of the carrier plate, in particular bearing pressure from heating devices arranged on the carrier plate and pressed against the bottom side of the hob plate. sagging, and sagging due to temperature effects due to heating during operation. The support carrier can extend below the carrier plate with an area for engagement from below and above the carrier plate with an area for engagement from above. As a result, the support carrier can partially support or prevent sagging of the carrier plate from below. In the transition region where the support carrier switches from the region for engagement from below to the region for engagement from above, in particular also in this region support the carrier plate or use the carrier plate to avoid unwanted warping of the carrier plate. To prevent this, it is particularly easy to connect the support carrier and the carrier plate to one another. Advantageously, the length or linear extension of the area for engagement from below and/or the area for engagement from above is at least 10% to 25% of the length of the support carrier. Since the surface or plane of the carrier plate is penetrated from bottom to top or from top to bottom, not only an at least partial direct support of the carrier plate by a carrying carrier is possible. Instead, better variability can also be achieved in this way to the effect that there is an area both above and below the carrier plate in which the support carrier is not extended and thus causes no disruption.

In a refinement of the invention, the support carrier may be in the form of an independent component produced separately from the carrier plate. Then, in the final hob, the support carrier can be fastened to or connected to the carrier plate, for example in a captive manner or in such a way that it can no longer be released without breaking. Some connections, such as threaded connections, have the advantage that they can be released again, for example for repair work or replacement, whereas a retaining connection for this purpose has the advantage that it is not released during operation and is therefore more permanent and safer. Furthermore, a retaining connection of this kind can often be established more easily in an automated manner when assembling the hob, ie when connecting the carrier plate and the support carrier. A possible way to do this is described in more detail below.

In a further refinement of the invention, the support carrier can be connected to the carrier plate in particular at its both end regions relatively close to each outer end, for example at a distance of at most 5% or 10% of the length of the support carrier. At least one additional connection to the carrier plate can be provided in a central or intermediate region of the support carrier located between the end regions. Thus, a three-point fastening can be achieved, which advantageously helps primarily to prevent sagging in the middle region of the carrier plate. The connection to each other in the intermediate region of each of the support carrier and carrier plate can 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, the distance advantageously being equal to the length of the support carrier. 30% to 45% of As an alternative, it is also possible to provide the connection between the support carrier and the carrier plate exactly in the intermediate region where the maximum load or deflection of the carrier plate is expected and thus the maximum support should be provided.

The above-mentioned connection of the support carrier to the carrier plate in the intermediate region can be realized by means of a retaining section. A retaining section of this kind may protrude from the support carrier in such a way that an elongate retaining slot is formed between said retaining section and the remainder of the support carrier, preferably approximately parallel to the support carrier. Sections of the carrier plate can be engaged in the retention slots for connection and retention purposes. A fastening of this kind can again be released very easily, for example by moving the support carrier in its longitudinal direction or in the longitudinal direction of the retaining slot, provided that this movement is inhibited by the remainder of the connection between the support carrier and the carrier plate. , a support connection acting at least 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, the retaining section engaging the area of the support carrier can also protrude from the carrier plate.

Said retaining slot may extend parallel to the plane of the hob plate (which is advantageously the plane of the carrier plate) or at a very flat angle. An angle of this kind may be between 0° and at most 10°, in particular 0°. As an alternative, the angle may be intentionally flat, but not too small. An angle of this kind may be between 15° and 30° to the plane of the hob plate or carrier plate. As a result, insertion of a section of the carrier plate into the retaining slot can be made more easily with a movement extending obliquely with respect to the plane of the hob plate or carrier plate.

In another refinement of the invention, the support carrier can be fastened to the carrier plate in the form of a connection by means of material deformation, which substantially corresponds to the above-mentioned captive connection. In this case, a possible alternative to the screw connection involves riveting or caulking, in particular the fastening section provided on the support carrier. As an alternative, a fastening section of this kind can also be bent in the manner of a bending lug or a retaining lug. Riveting can first be done by separate rivets in addition to the support carrier and carrier plate. As an alternative, also as in the case of caulking, it is possible to pass the fastening section in one part through the plane of the other part, advantageously through a correspondingly formed opening in the other part, and then release the connection. It may be widened or caulked to prevent it. In this case a kind of integrated rivet is provided.

In a refinement of the invention, the carrier plate may have openings, possibly relatively large openings, at least in the middle region. As is generally known for induction hobs, openings of this kind may be provided in the area under the carrier plate, for example for the electrical connection of the heating device. The support carrier can at least partly extend through this opening, in the process extending from the area for engagement from below to the area for engagement from above or vice versa through the plane of the carrier plate in the area of this opening. Thus, there is no need to create a separate opening for the support carrier to pass through the carrier plate. When the support carrier extends approximately centrally through this opening, the opening can also be used more conveniently for practical purposes, such as for example the electrical connection described above. In another refinement of the invention, the rim of said opening engages, as a section of the carrier plate, into the aforementioned retaining slot of the support carrier, so that it is possible for the retaining section of the support carrier to extend 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 refinement of the invention, it is also possible that the support carrier has two retaining sections each having a retaining slot in the direction of the support carrier, which also extend in opposite directions relative to one another. A separate rim of the aperture may engage the two retaining slots. In this case, opposite rims of the opening may engage retaining slots of this kind. Since this generally cannot be achieved with a linear movement of the support carrier relative to the carrier plate, the support carrier can be mounted by way of a separate retaining slot after insertion of the retaining section into the opening and subsequent rotation. During attachment, the support carrier can be extended relative to the opening so as to span a relatively long area of this opening, and due to rotation or corresponding mounting movement, the spanned length of the opening becomes shorter, in the process, Edges of the opening 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 region for engagement from below. The support carrier can be fastened to the carrier plate from below in the area for engagement from above, ie from the other side in both areas. This is possible in particular advantageously with the said caulking section of the support carrier protruding from the support carrier as a fastening section and engaging via a corresponding opening or caulking opening of the carrier plate. In this case, caulking takes place respectively 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 a fastening section of this kind or when the fastening section itself is used as a riveting arrangement. A threaded connection can also be provided, the bending section of the support carrier advantageously being provided with a thread or screws in the form of self-tapping screws which pass through the carrier plate and are screwed into the support carrier. The support carrier advantageously has a greater thickness than the carrier plate, so that the thread of the screw can be engaged here more effectively.

In a refinement of the invention, an operator control device which mainly has operator control elements in addition to control functions can be arranged in the front area on the carrier plate. These operator control elements can for example have touch sensors and can be pressed against the bottom side of the hob plate as is well known from the prior art. A heating device, advantageously an inductor for an induction hob, can be arranged in the rear region of the carrier plate which makes up the majority of its surface area. This heating device covers most of the surface area of the carrier plate, in particular at least 70% or even 80%. And the support carrier advantageously extends below the carrier plate in the front area by means of an area for engagement from below. The support carrier extends above the carrier plate in the rear area by means of an area for engagement from above. In this case, the support carrier can extend between adjacent heating devices in this rear region. If the support carrier has a narrow design and is rather tall, it is advantageously provided to have a certain height for stiffness against deflection, so that it does not require much space and therefore also between adjacent heating devices at a small distance from each other. can be easily extended.

In the front area with the operator control device, the support carrier extends below the operator control device disposed on the carrier plate, so that the operator control device does not need to be divided and has no passage for the support carrier. The operator control device can therefore be designed as a continuous printed circuit board on which, for example, electrical components and in particular also operator control elements or touch sensors are arranged. The placement of the support carrier in the rear region above the carrier plate is advantageous since the region below 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, this is advantageous since the power electronics and other components possibly also requiring a cooling air flow can be installed below the hob without adverse effects.

In principle, the orientation of 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 sagging. As explained above with respect to the operator control device and the heating device, a profile of the support carrier in the direction of the hob from rear to front is preferred because of the advantageous areas for engagement from above and areas for engagement from below. because it can be divided. Here, in a first refinement of the invention, a single support carrier may be provided in this case to support the carrier plate, which extends over an intermediate region of the carrier plate and preferably over a key point of the surface area. This is believed to be advantageous also in hobs, for example presenting a sort of mirror-symmetrical division of the heating devices between left and right, so that the support carrier can be easily extended between said heating devices.

In a second refinement of the invention, mainly on an extra-wide hob, three heating devices or three groups of heating devices (whichever group is approximately the same size) can be provided adjacent to each other. . Here, exactly two support carriers can be provided, which in this case run parallel to each other from front to back and each extend between adjacent groups of heating devices. Accordingly, the carrier plate of a wide hob of this kind, usually having a width of about 90 cm, can also be effectively supported against sagging.

In one example of the invention, the support carrier can be constructed from or produced from a flat material. The thickness of the flat material may be between 1 mm and 5 mm, advantageously approximately 2 mm to 5 mm. A relatively thin support carrier of this kind can be produced, for example, from metal, in particular aluminum. The support carrier may have only one or two support sections projecting at right angles to support the carrier plate. The support section ensures that the longitudinal cross-section of the support carrier is upright and the support carrier is approximately perpendicular to the surface area of the carrier plate or to the carrier plate itself and thus has a high degree of rigidity against deflection of the carrier plate. It is to do. If two protruding fastening sections of this kind are provided, it can be particularly advantageous if they protrude from the support carrier in different directions so that tilting in both directions can be reliably prevented. In a possible example of the invention, these fastening sections can also serve to fasten the support carrier to the carrier plate, for example by means of screws or rivets that are passed through, as generally described above. As an alternative, the fastening sections may have fastening lugs at their outer ends which are again angled and extend in their part approximately perpendicular to the surface area of the carrier plate. These fastening lugs can be used for the aforementioned riveting, caulking or bending.

A flat support carrier having a profile substantially perpendicular to the surface of the carrier plate advantageously extends along the carrier plate or can be contact-connected or contacted with the carrier plate, in particular an edge, at least over a relatively large area of its length. In particular, it provides an area for engagement from below to support the carrier plate against sagging at the bottom in a very simple manner.

The height of the support carrier is intended to be between 2 cm and 3 cm, advantageously between 1 cm and 1.5 cm, so that the surface area of the carrier plate either upwards in the area for engagement from above or downward in the area for engagement from below. It protrudes upward by a maximum of this much. Since the hob, in particular the induction hob described above, is intended to be constructed as flat as possible, the overall height should not be increased unnecessarily or at all by the support carrier. Therefore, the support carrier must not protrude above the heating device in the area for engagement from above or below the power electronics system or the like for the heating device in the area for engagement from below.

These and further features are evident from the description and drawings as well as from the claims, and it is possible to implement each of the individual features singly or separately in the form of subcombinations for embodiments of the present invention and in different fields, Each of the above individual features can be an advantageous and independent protectable embodiment claimed herein. The subdivision of this application into individual sections and subheadings does not limit the general validity of the statements set forth thereunder.

1 and 2 are a side view and a plan view, respectively, of an elongate support carrier 11 made of a material between 2 mm and 5 mm thick, advantageously aluminum or sheet steel. The support carrier 11 has an area 13 for engagement from below on the right side and an area 15 for engagement from above on the left side, the area 15 for engagement from above being almost three times as long. to be. Zones 13, 15 are connected by a transition zone 17 in the form of a double bend. The support carrier 11 has an angled fastening section 19 at the right end in the area 13 for engagement from below and at the other end in the area 15 for engagement from above. As shown in the following figures 3 to 5, for fastening purposes the fastening section 19 may be provided with a screw connection or a riveted connection to the carrier plate.

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

The fastening sections 19 are angled in a different direction from the support carrier 11 to allow a tilt-resistant connection to the carrier plate, which, individually, the support carrier 11 attaches to said carrier plate. It can stand upright at right angles to the

3 to 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 for induction hobs, and is constructed from a 1 mm to 2 mm thick aluminum sheet. Also mainly seen in the perspective view, the carrier plate is generally flat in its middle region and folded down at its edges. However, this is known in principle and contributes to stabilization and mounting on the glass frame of the hob. In the middle region, the carrier plate 24 has an opening 26 which is also used, for example, to guide the connection cables of inductors located on the carrier plate 24 down to the electrical connections. However, this is known.

The support carrier 11 extends below the carrier plate by means of an area 13 for engagement from below and above the carrier plate by means of an area 15 for engagement from above. In both regions, the support carrier bears directly on the carrier plate 24, which is primarily important for the support function in region 13 for engagement from below. The support carrier 11 can extend from the bottom to the top only through the rectangular opening 26 or within the through slot 27 as provided herein. This through slot 27 extends from the right rim of the opening 26 . Consequently, it is possible, for example, for the support carrier 11 to change somewhat earlier from the area 13 for engagement from below to the area 15 for engagement from above and extend above the carrier plate 24 .

The support carrier 11 is fastened to the carrier plate 24 by screws 29 having threading cut into the fastening section 19 of the support carrier 11 . Thus, the screw 29 for the fastening section 19 of the area 13 for engagement from below is passed from the top and is located, for example, on the support plate 24, while the area 15 for engagement from above A screw 29 for the fastening section 19 of the bottom extends from the top to the top. Instead of screws 29 of the kind mentioned above, rivets or other interlocking connecting elements can also be used.

Additional fastening in the middle region is provided in that the retaining section 21 is engaged under the left rim of the opening 26 with this rim engaging the retaining slot 22 . As a result, a simple force-fitting fastening that prevents downward deflection of the middle region of the carrier plate 24 is possible.

3 shows that the support carrier 11 does not extend completely in a straight line, or upwards from its free end to the retaining section 21 at its lower edge, as at the upper edge of the region 13 for engagement from below. It is shown that the area 15 for the engagement from Accordingly, the carrier plate 24 is pre-folded upward to some extent 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 deflect downward to some extent, while still being flat or level and in particular parallel to the hob plate.

The plan view of FIG. 4 shows that a plurality of slots 31 are formed in the carrier plate, which later form first four square fields for respectively supporting induction coils. Rounded slots 31 are formed at some corners of these fields. These slots prevent excessive heating within the carrier plate 15, which is primarily made of metal. Secondly, the slots can have a beneficial effect on deformation of the carrier plate 24 due to high temperatures.

In the front area 25 (on the right side of FIG. 4 ) of the carrier plate 24 an operator control device can later be fitted. This is shown in the sectional view in FIG. 6 by means of a hob 33 according to the invention comprising a hob plate 34 shown using dashed lines, in which the operator control device 35 is shown. Other components of the hob 33 , in particular the power electronics 39 and the like are supported by the transport tray 37 below the carrier plate 24 .

The perspective view of FIG. 5 , together with the cross-sectional view of FIG. 3 and the plan view of FIG. 4 , shows that the three edges or rims of the opening 26 are provided with downward bent elongated lugs. This serves to ensure that the cable can be guided downward over the edge or rim and that the cable is not damaged during the process by the sharp metal edge facing downwards. However, the edge inserted into the retaining slot 22 of the retaining section 21 is intended to be straight at least within the region of the retaining slot 22 . Otherwise, insertion is not possible.

7 to 9 show an alternative refinement of the support carrier 111 having on the right an area 113 for engagement from below and on the left an area 115 for engagement from above, again again 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. 1 . However, there is no fastening section 19 and retaining section 21 here. Instead of them, three spreading lugs 120 are provided. In practice, only two spreading lugs are required, the outermost lug mainly contributing only to the lateral fixation. The outermost lug may also be in the form of a spreading lug, but this need not be the case from a functional point of view. The plan view of FIG. 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 compared to the arrangement of FIG. 3 , which each prevents tilting. show what The spreading lugs 120, as shown in the enlarged detail according to FIG. 10 of the fastening of the intermediate spreading lugs 120 to the carrier plate 124, here indicated by arrows, the spreading lugs 120 ) extends through the corresponding recess 128 of the carrier plate from below, then the spreading lug 120 is bent or struck by a flat hammer or the like, in a manner similar to a riveting device. As a variant, the spreading lugs 120 can be struck by an edge or wedge, with the result that the spreading lugs 120 move away from each other to form a gap between the left half and the left half performing engagement with the recess 128. divided into right halves. However, this is in principle known to the person skilled in the art.

Since the carrier plate 124 is positioned on the support carrier 111 in the region 113 for engagement from below at the top and supported by said support carrier, the spring for fastening purposes in the region 113 for engagement from below Leading lugs 120 or the like are not required.

The sectional view through the hob 133 according to FIG. 11 once again corresponds substantially to the hob of FIG. 6 , only here there is no hob plate. An elongated operator control device 135 is provided in the area shown on the right side of FIG. 11 , which area is the front area of the finished hob 133 . This is again more clearly shown in the plan view of FIG. 12 and the perspective view of FIG. 13 . As an example, eight induction coils 140 are disposed or positioned on a carrier plate 124 in an adjacent area forming a heating zone when the hob is completed. The cables of the induction coil extend partly through corresponding openings of the support carrier 111 as power connections 141 . Control connections are extended in this way. Also, similarly, a temperature sensor or the like having a connection may be additionally disposed on the induction coil 140. In principle, the connecting portion can also be extended as described above.

Referring to Figures 12 and 13, how one row of four induction heating coils 140 are adjacent to one row of four additional rows in a particularly customary wide hob with a width of 90 cm, so that a total of three rows of four induction coils 140 It is easy to imagine what this provides. In this case, a support carrier 111 of this kind is intended to extend between two rows of four in each case to support the carrier plate.

The perspective view of FIG. 13 also shows that, in particular in the front area of the hob 133 or carrier plate 124 , the support carrier 111 is below said carrier plate, to allow simply a continuous design of the operator control device 135 . It shows specifically and clearly that it is advantageous when extended from . Construction and installation of the operator control device is greatly simplified in this way. Also here an automatic support of the carrier plate 124 is provided.

However, as shown in the cross-sectional view of FIG. 11 , there is no space limitation in the rear area of the hob 133 or in the area 115 for engagement from the top of the support carrier 111 . The three small spreading lugs 120 cause no interruption here, see above in this respect.
