Description

Holding device for a carrier of a radiator of a hob and hob, in particular induction hob

The invention relates to a holding device for a carrier of a radiator of a hob, which has to mi ndest egg n spring element on which the carrier is positioned. Furthermore, the invention relates to a hob, in particular an induction hob, with a corresponding holding device. Induction hobs have inductors, which are arranged under a glass ceramic. These specific heaters include a coil spirally wound in a plane and held by a bobbin holder which is particularly made of plastic. This bobbin holder is arranged on a support. Such a configuration is known for example from EP 1560 462 A2.

Such a carrier is by means of spring elements, which support the carrier from below, contained in the hob.

In Fig. 1, such known from the prior art Technique holder in an induction hob 1 is shown in a perspective cutout view. This holding device 2 comprises the carrier 3, which is bounded by a side wall. The carrier 3 accommodates the coil holder 4, which is disc-shaped and has recesses 5 in which the coil 6 is contained. The holding device 2 comprises spring elements 7, which has a helix-shaped wound spring 8. These flexible ignition modules 8 h atin hin a new stabilizing part 9, which is a solid and rigid element. This stabilizing part 9 is tower-shaped and by the fixed and fixed positioning lateral mobility of the spring 8 should be avoided, so that only resilient movements can be done vertically and thus up and down. Such a design is on the one hand component-intensive and on the other hand consuming in terms of assembly, so that there are considerable costs. In addition, the functionality is limited. It is an object of the present invention to provide a holding device for a carrier of a radiator of a hob and a hob, in which the resilient mounting of the carrier can be configured reduced and functional. This object is achieved by a holding device, which has the features of claim 1, and a hob, which has the features of claim 15.

A holding device according to the invention for a carrier of a heating element of a cooking hob comprises at least one spring element on which the carrier can be positioned. In its specification, the spring element is a material strip that is too simply bent. In such a configuration, a component reduction of the bearing of the carrier can be made possible, since only a specific shaped and formed spring element is required at a bearing point. On the one hand can be ensured by the specific shape of the spring element of the sufficient spring effect and beyond the required stability of the spring element can be ensured by the curved plate-like strip. Due to this configuration, it is no longer necessary, as in the prior art, to use an otherwise specified spring in the form of a helical winding of a wire and a supporting stabilizing element. In addition to a component saving thus an improved spring effect can be achieved.

Preferably, an S-shape or a U-shape of the bent spring element is formed. In particular, a multi-curved shape is thus provided. Under an S-shape is generally understood any configuration which is formed with two different directions of curvature corner-free plate-like strip. Likewise, this is understood to mean a plate-like strip configuration which has an angled shape which, arranged at an angle from at least one middle section and arranged at the opposite end of the central section and further upward and downward in different directions to the middle section, in particular flat plate-like sections, includes. The plate nature of the strip results from the fact that the width of the strip is much larger than the thickness.

Preferably, the spring element has a first arcuate portion, which is followed by a second arcuate portion, wherein the arcuate portions have different directions of curvature and viewed from the carrier in the vertical direction below and below each other staggered. The positioning of the specifically bent spring element is thus such that, due to the bending, the sections viewed vertically downwards can deform, so that viewed in the vertical direction a spring effect occurs and thus a relative movement of the carrier is made possible.

Preferably, the spring element is arranged so that it is in a plan view of the carrier in terms of its area size completely below the carrier. On the one hand, space can be saved laterally and, moreover, the mechanical load and the spring action can be optimally matched to one another.

Preferably, the first arcuate portion has a side-laid U-shape. This means that the two parallel legs of the U-shape viewed in the vertical direction are arranged one below the other. Due to the specific U-shape can thus be made possible with a force from above a relative movement of these two legs of the U-shape, so that a vertically resilient movement of the carrier is ensured. This first arcuate portion is viewed in the vertical direction to the underside of the carrier and facing the carrier portion. Preferably, the second arcuate portion has a rectilinear end portion. In this context, the second arcuate portion is not formed with the U-shape but substantially an angle formed with a rounded edge, the legs of which extend in particular at an angle of 90 ° to each other. Preferably, a leg of the U-shape of the first arcuate portion opens directly into the leg of the second arcuate portion, wherein these legs opening into each other are oriented substantially parallel to the bottom of the carrier and thus are oriented substantially horizontally. It can also be provided that these nested legs of the two sections are arranged inclined at a relatively small angle relative to the bottom of the carrier.

Preferably, the rectilinear end portion of the second arcuate portion is designed as a male element in a plug-in device, which is designed for fastening the spring element to a holding plate. Thus, a position stable, yet easy to install connection can be created, in particular the specific shape and orientation of the end portion with a quasi plate-like insertion allows a particularly stable attachment. Preferably, a plug-in element with a plug-in tab is arranged on the leg facing the support of the U-shaped first arcuate portion, in particular at its free end, which is designed for insertion into a receptacle of the carrier, in particular the plug-in tab for insertion through a hole in the Bottom of the carrier is formed.

In particular, the spring element has a first planar section, adjoined by a second planar section arranged at an angle, in particular 90 °, oriented upwardly in relation to the first section, and a third planar section is formed, which extends at an angle, in particular 90 °, oriented towards the second section at the second section, in particular at the end remote from the first section of the second section. Such an embodiment allows a special stability and easy installation.

Preferably, the third portion is formed as a male element in a plug-in device for fastening the spring element to a holding plate and to its

Side edges are formed retaining bracket, which are designed to engage with a retaining wall of the retaining plate. This is a particularly advantageous embodiment, as a quasi a rear engagement of the retaining plate is made possible by the spring element and a particularly stable attachment with high power consumption of the spring element without

Position change is possible.

Preferably, the retaining wall is formed integrally in the retaining plate and in the assembled state of the spring element with the retaining wall, the retaining wall is parallel to third section, in particular at this fitting formed. As a result, the aforementioned advantages can be improved again and a particularly flat construction design can be made possible.

In particular, the retaining wall merges with a curved retaining web into the retaining wall and, at the side of the retaining web, free spaces are formed, into each of which one of two section parts forming the third section extends. By such

Design can virtually a toothing between the spring element and the

Holding plate are created, creating a particularly mechanically stable connection is created.

Preferably, the third portion has an embossment which is formed on the holding plate for connection to the holding plate with a compatible holding element. In such an embodiment, the connection can be made quasi by a compression. Preferably, a plug-in tab is arranged on the carrier facing the first portion, in particular at its free end, which for insertion into a

Receiving the carrier is formed, in particular the insertion tab is formed for insertion through a hole in the bottom of the carrier, wherein the insertion tab is formed slotted. As a result, the tab can be used in the inserted into the hole and extending therethrough state for further attachment of a component in the slot, whereby the functionality is increased.

Preferably, the holding device has a holding plate for receiving the spring element, on which an insertion region for the spring element is formed. In particular, it is thus provided that the connection between the spring element and the retaining plate is realized by a plug connection. This is a montagespecific connection to be generated very quickly, which in addition is non-destructively solvable and thus advantages are given when replacing or maintenance.

Preferably, the insertion region is formed with two adjacent and spaced-apart Einsteckbügeln. These preferably run in the vertical direction and parallel to each other. The plug-in area is therefore very reasonable and easily accessible, so that the insertion of the spring element can be done very smoothly. In particular, this can be avoided Verspreizungen or jamming.

It is preferably provided that the Einsteckbügel are integrally formed with the retaining plate. In addition to a reduction in component manufacturing can thus be faster and cheaper. In addition, undesirable tolerances or relative movements between the retaining plate and the Einsteckbügeln be avoided by such a one-piece design. This also makes it possible to ensure the permanently positionally stable attachment of the insertion clips, so that in this connection there are no new displacements or movements of the insertion bracket, which may lead to an expansion or jamming upon insertion of the spring element would cause.

It can also be provided that the insertion region has only a frontally closed boundary wall instead of the insertion clip.

The spring element is preferably a part designed separately for the holding plate. On the one hand, therefore, the assembly and disassembly can be easily ensured and moreover, individual parts can be easily replaced. Preferably, the retaining plate is a side wall of a trough-like receiving device for the radiator. An already existing component, namely the side wall, is thereby formed multifunctional and by the relatively stable receiving device and the spring element and thus the carrier holds and receives, in this regard, a robust and stable attachment can be ensured. Mechanical overloads of the component to which the spring element and the carrier are attached, can be avoided.

Preferably, a plug-in element with a plug-in tab is arranged on the leg facing the carrier of the U-shaped first arcuate portion, in particular at its free end, which is designed for insertion into a receptacle of the carrier. In particular, the insertion tab is designed for insertion through a continuous hole in the bottom of the carrier. The most purposeful and easy attachment of the carrier to the shuttle or d Spring elements is ensured. In addition, an undesirable falling out or slipping out of this connector can be avoided by the insertion tab extends through the hole in the bottom of the carrier.

Preferably, in the case of an S-shaped design of the spring element, it is provided that the first section has a projecting lug-like detent element, which in particular is an obliquely forwardly standing strip, which is formed integrally with the first section. In particular, it is further provided in addition or instead that the second section at least one projecting bow-shaped spring member, preferably two equal and spaced from each other

Spring parts, comprising. The spring parts are formed integrally with the second portion. These can be formed at the free ends with downwardly curved end tab, so that no splaying or scratching of the contact surface is associated. Additionally or instead, it may be provided that the third section comprises at least one support leg, preferably two support feet spaced apart from one another, and / or a clip-like holding web. The support legs and the holding web are formed integrally with the third section. By such a configuration of the

Spring element can be created a particularly stable and positionally secure arrangement. Preferably, in the assembled final state of the holding device with the

Carrier arranged the tab-like locking element seated on a bottom top of the carrier and / or arranged the bow-shaped spring member adjacent to a bottom underside of the carrier and / or a support leg on a bottom top of a

Seating device arranged on seated and / or arranged the clamp-like holding web on an outer side of the holding plate fitting. As a result, various mechanical contact points can be created, which ensure reliable positioning of the components.

In particular, it can be provided that the first section is horizontally oriented and has a recess through which a plug-in tab can be inserted in the bottom of the carrier. In particular, the spring element may alternatively be formed U-shaped and have a first strip-shaped portion, which adjoins an arranged at an angle, in particular 90 °, the first portion second strip-shaped portion, and a third strip-shaped portion may be formed, which at an angle , In particular 90 °, oriented upwardly to the second portion on the second portion, in particular on the first portion remote from the end of the second portion, is arranged.

It when the spring element, the support plate and the carrier are connected to each other only by plug connections is particularly advantageous. Other fasteners such as screws, rivets or the like are therefore no longer required. Due to the specific shape design and arrangement of the spring element, both a plug connection at the connection point between the spring element and the carrier and a plug connection between the spring element and the holding plate are sufficient in order to be able to connect these to each other in a positionally stable and mechanically wear-resistant manner. Here, too, in addition to a component reduction in the form of the saving of separate connecting elements, the assembly can thus be significantly shortened.

Furthermore, the invention relates to a cooktop with at least one radiator, the cooktop having an inventive old device and an advantageous embodiment thereof. This is particularly preferably provided in induction hobs, in which such carriers are provided to receive and hold inductors. However, this can also be provided in radiant fields with radiant heaters. Further features of the invention will become apparent from the claims, the figures and the description of the figures.
