Induction cooking hob with a housing

[0001] The invention relates to an induction cooking hob with a housing for the induction cooking hob to cover a lower side of the induction cooking hob.

[0002] From DE 202007001432 U1 it is known that a housing is placed as a cover on the lower side of a cooking hob.

Thus, the inside of the cooking hob must be protected from dirt, as well as damage during commissioning and assembly.

[0003] From DE 202009012872 U1 it is also known that a housing as a cover is provided on the induction hob, where it can be made of plastic as an advantage.

[0004] From DE 93 05 316 U1 a countertop for gas burners or electric hobs is known, consisting of several individual components.

The individual components connect laterally and form a housing.

As a peculiarity, in the individual components feed pipes or gas feed channels are formed to the gas burners of the individual gas plates of the countertop.

Thus, you can save an additional input as well as the cost of your installation.

By installing the individual components to each other, the individual pipe sections are joined together with each other in a tight manner and so that they gas.

[0005] From WO 2004/060020 A1 an induction cooking hob with a plate and several inductors below, which are arranged in a housing, is known.

The housing can have two parts of plastic profile formed in a single piece of the bottom of the housing. These plastic profile parts can themselves be fixed in turn in a cooking countertop frame, for example screwed.

In this case, both parts of the plastic profile have a distance from each other, since they are only slightly wider in size than the inductors themselves.

[0006] From EP 1 445 544 A1 an induction cooker is known.

It has a support plate, which houses heating elements, a synthetic material housing, which extends under the support plate, connects to it detachably and houses an electronics for the activation of the heating elements, and a plate Ceramic hob, which extends above the support plate on its heating elements, connects to it in a removable way and houses a kitchen battery in its upper part.

The synthetic material housing consists of inverted segments that are joined together in one piece or detachable from each other or also completely separated.

Objective and solution

[0007] The object of the invention is to create an induction cooking hob with a part of the housing initially mentioned, with which the problems of the state of the art can be avoided and, in particular, to form a safe and advantageous housing, so as of multiple use and manufacture it economically.

[0008] This task is achieved by means of an induction cooking hob with the characteristics of claim 1.

Advantageous configurations, as well as preferred ones of the invention are subject to the other claims and are explained in more detail below.

The text of the claims is made by reference explicitly to the content of the description.

[0009] It is provided that the housing has at least two individual components, consisting of plastic.

Individual components are understood here as larger and flat individual components and no small parts such as screws or similar. Above all, the bottom side of a cooking hob must be protected and covered with the housing, as it was initially exposed.

The part of the housing consists simply of plastic, so that an electrically insulating protective cover can also be created and, therefore, that protects against the contact of parts under tension.

[0010] It is provided according to the invention, that at least these two individual components are identically formed and are arranged in an identical arrangement or turned to the housing.

These two then form the housing either together or for greater advantage alongside other individual components.

The application according to the invention of several identical individual components allows a simpler manufacturing, since the cost of machines and compression or plastic injection molding machines decreases disproportionately through the reduction of the size of the individual components in comparison with the housing

Also the subsequent handling is lighter, there should not be manipulated parts not so large or not always the total housing.

In addition, it is possible to manufacture different housings, which always have the same individual components or the same two individual components.

By the provision of other individual components or other individual components shaped differently, particularly, arranged laterally or between them, then an adaptation to the desired hob can be produced respectively.

Therefore, other parts are also possible as a fully modular structure of a housing.

Due to the possibility of an identical or rotated arrangement, particularly at 180 ° in the area of the housing, a larger variation in the composition is also possible.

[0011] According to the invention, the various individual components are formed and arranged so that they extend respectively over a total width of the total housing, where this part of the housing is then lengthened rectangularly.

Along the length of the housing, several individual components are attached to each other or joined together.

This means that the length of a component corresponds to the width of the housing, but that the length of the housing is clearly greater and is formed from the width of the individual components placed and other parts.

[0012] An induction cooking hob according to the invention therefore presents the individual parts or components mentioned as the housing on the lower side as a cover.

In this case, a housing fixation can be produced on the lower side of the induction cooking hob by means of a connection resistant to the connection means, which are advantageously adhered to the lower side of the cooking hob.

Especially advantageously, the housing consists only of the individual components previously mentioned without other individual components of the housing type, only particularly of two, three or four such individual components.

[0013] In a later configuration of the invention it is still possible to provide for other housing parts to be formed equally identically with respect to each other, but simply otherwise to the previously mentioned individual components.

Thus, the idea of the modular and simplified structure of the housing can be pursued as an advantage.

Also these other pieces can be arranged identical with respect to each other or rotated with respect to each other.

[0014] It is possible that the identical individual components have essentially a cover function and no other function.

Right on a cooking hob, these can be used to cover or protect your heating devices.

But in this case, the heating units are not fixed to the housing or the individual components, but advantageously on top of a cooking plate.

The other previously mentioned parts of the housing can serve to cover, but also advantageously for the housing, a control and / or electronic power and / or electrical connections for the heating devices.

In this case, you can even adjust pieces of this in these other pieces or look at it, because these other pieces can exercise here more than just a cover function.

[0015] In the embodiment of the invention, it can be provided that these identically shaped individual components relative to each other are located in an external area of the housing and, for example, form a left edge and a right edge.

In this case, these can be arranged twisted relative to each other or rotated 180 ° advantageously as a symmetrical configuration.

The other parts of the housing located in an intermediate zone can, when there are several, be formed equally identical with respect to each other.

In this case, these can be arranged in the same alignment, alternatively also twisted or rotated 180 °.

[0016] A symmetry of the individual components allows their identical arrangement with respect to each other or rotated 180 ° with respect to each other.

A symmetry is advantageously an axial symmetry with a center of long sides of an elongated shaped component.

[0017] Advantageously, the individual components may have grooves, which are formed particularly as ventilation openings.

Thus, a cold air supply and, therefore, the cooling of the induction heating devices can occur especially with induction cooking countertops.

The ventilation openings should be arranged at the margin as in a central area of the component, particularly, also not to weaken its stability too much.

[0018] In an advantageous configuration of the invention, the individual components of the housing, particularly also together with the other parts previously mentioned, can be joined without tools to one another or fixed to each other.

This can occur by connection or fixation, possibly also by inseparable compounds such as welding or friction welding or ultrasonic welding and gluing.

It is also possible to screw, which is kept securely and can be released again.

[0019] Advantageously, the finished housing has an inherent stability, so that it not only stays completely flat and forms a flat cover, but can also simply have a support and / or carrier function for the cooking countertop or functional units of the cooking hob.

[0020] Therefore, a stable fixation of the individual components is formed between them, as well as possibly with other parts advantageously.

[0021] As a whole, the cuvette-like housing can be formed, so that with a circular edge it can reach a cooking plate on one side or its lower side.

On the other hand, it has enough space or depth for the functional units, particularly the heating devices.

Said cuvette can be formed both from the individual components, as well as possibly from other parts.

Advantageously, the total cuvette is only formed from the individual components, especially advantageously from two to four individual components.

Said circular edge is especially advantageously formed of all the individual components and also possibly also of other parts of the housing, preferably, only of the individual components.

[0022] Through the application of the individual components, according to the invention, advantageously two individual components, as well as other parts, a type of modular structure can be created for a housing for a cooking hob.

Depending on the structure and size of the hob you can combine a certain number of these pieces.

In this case, it is also possible that a component mentioned, for example, serves as a cover for two heating devices or induction heating devices of a cooking hob and another part for housing its power supply, in particular, control and power electronics.

Of such several pairs, a housing for a complete cooking hob can be formed, which can also be formed modular and has a variable number of such pairs of heating devices.

[0023] These and other characteristics are deduced in addition to the claims, as well as from the description and drawings, where the individual characteristics are performed respectively by themselves or some in the form of alternative combinations in an embodiment of the invention and in other areas, and may represent advantageous and patentable embodiments by themselves, for which protection is requested here.

The subdivision of the application into individual sections, as well as provisional titles do not delimit the statements set forth herein in their general validity.

[0024] The embodiments of the invention are schematically represented in the drawings and are explained in more detail below.

Detailed description of the realization examples

[0025] In Fig. A housing 11 according to the invention represented with a left component 13a and a right component 13b.

The parts are made of plastic, advantageously by plastic injection molding.

Notably, both identically formed and twisted individual components 13a and 13b are recognized relative to each other at 180 ° in the plane formed by them.

The individual components respectively have a deep bowl area 14a and 14b, which opens from the center outwards.

In the opposite direction, as well as the upper edge and the lower edge outwards, the cuvette areas 14a and 14b are limited by the cuvette edges 16a and 16b.

The outer edges 17a and 17b extend outwardly completely, which are especially useful for bonding on an induction hob.

While the bucket zones 14a and 14b are essentially closed, the enlarged areas that extend around have openings 20a and 20b.

These serve for the supply of refrigerated air, as well as possibly also for the saving of material.

The openings 20a and 20b are divided by the reinforcement flange.

[0026] In Fig. A first variant of the manufactured housing 11a is shown, in the case that the arrangement according to Fig. 1 between both individual components 13a and 13b has included an intermediate part 22.

This intermediate part 22 also has a deep bowl area 14c, as well as a bowl edge 16c. Since it is extracted upwards in the upper face completely, it sinks almost with the outer edge 17c present there.

Also, the lower outer edge 17c of the intermediate portion 22 extends in a line with the outer edges 17a and 17b of the individual components 13a and 13b to these two sides.

[0027] In addition, the intermediate part 22 has fixing devices 23 in the lower area, preferably for cables or other functional units of an induction hob manufactured, for example, a control or individual control or power components.

At the other end, a ventilation opening 24 is provided, which is configured in a manner known per se.

This can also be adapted to a kind of ventilation edge or duct for the ventilation opening 24.

[0028] In Fig. 3 an induction hob 26 is shown with a usual hob 27, advantageously, of ceramic hob.

On its lower side, the housing 11a corresponding to Fig. 2 is arranged or fixed to the bracket 29, for example, screwed.

These supports 29 can be formed in different ways and, for example, at an angle of sheet metal, which are stuck permanently on a lower side of the cooking plate 27.

In addition, these supports 29 may be formed peripherally and with the outer edges 17a, 17b and 17c of the housing 11, to achieve an essentially closed conformation.

The induction heating devices 28 are shown in strokes, which are arranged in the area of the individual components 13a and 13b, that is, within the projection plane respectively two followed by the bowl area 14a and 14b.

In the area of the intermediate part 22, a power electronics not shown is provided, as well as the control for the induction cooking hob 26.

In addition, it is recognized in Fig. 3, that at the front outer edge 17c of the intermediate part 22, therefore, under the fixing devices 23, the air slots 25 are provided.

Here, air can again escape, which has been sucked through the ventilation openings 24.

[0029] Another alternative configuration of the housing 11 b is shown in Fig. 4.

Similar to Fig. 1, two individual components 13a and 13b are provided, however somewhat more separated.

Among these are two intermediate parts 22a and 22b, of which each can be formed exactly as shown in Fig. 2.

In this sense it will be referred to.

With this housing 11 b, another induction cooking hob can be built, especially with modified power electronics.

Alternatively, other induction heating devices can be arranged in the large area of the bowl areas 14c and 14d.

In this case, it must also be recognized that both intermediate parts 22a and 22b are respectively provided in the same alignment.

[0030] Another variant of a housing 11 c is shown in Fig. 5.

Based on Fig. 1, it consists only of both individual components 13a and 13b, which are attached or installed directly with each other.

The area formed by the bowl areas 14a and 14b is not especially large, but it may be sufficient for the arrangement of different functional units of a cooking hob, for example, two or four induction heating devices, as presented by an electronic of integrated power as individual components.

[0031] Again another alternative configuration of the housing 11 d is deduced in Fig. 6.

Here, in variation to Fig. 5, both individual components 13a and 13b are arranged in the same direction and identically, therefore, in comparison with Fig. 5 the right single piece 13b rotated 180 ° in its flat.

[0032] The precise fixation of the individual components 13, as well as the intermediate parts 22 to each other, as well as in the induction hob 26 is not represented here in more detail.

This is slightly imaginable for the expert.

In addition, it is slightly imaginable, the introduction at the outer edge 17a and 17b carried out as double-edge up and down according to Fig. 1 of a seal or the like.

Likewise, an elongated support of Fig. 3 can fit here.
