Description

The present patent application takes the priority of the German patent application DE 10 2018 206 318.4 claim, the contents of which are incorporated herein by reference.

The invention relates to a frame device. Furthermore, the invention is directed to the use of a frame device, a hob system, and an arrangement of a hob system.

By prior public use, frame devices for a cooktop system of the prior art are known. Such frame devices are integrally formed. The cost of materials for the production of one-piece frame devices is high and their transport is uneconomical due to the packaging necessary for a sufficient stability and these framework devices to their own dimensions.

Such frame devices are also known from the DE 10 2014 209 955 A1 and the EP 2 602 556 A2 ,

It is an object of the invention to improve a frame device.

This object is achieved by a frame device with the features of claim 1. According to the invention, it has been recognized that a frame device for a cooktop system with at least two frame parts, which are present in a transport state separated from each other, are connected to each other in an installed state and can be transferred from the transport state to the installed state, is particularly economical to produce and transportable. The at least two frame parts completely surround the hob opening in the installed state. This is to be understood that the at least two frame parts completely enclose the hob opening in the installed state. Furthermore, the at least two frame parts each have at least one visually refined visible surface. Under the visible surface are all those surfaces of the at least two frame parts to understand, which in the installed state, especially in the mounted state of the frame device and the hob system, in particular from the perspective of an operator of the cooktop system, are visually perceptible. Under the optical Refinement of the at least one visible surface is to be understood that it is polished and / or brushed and / or blasted and / or stained and / or sanded and / or painted. The frame device is thus visually particularly appealing. Preferably, all visible surfaces of the at least two frame parts are optically finished.

In the transport state, the at least two frame parts can be arranged to save space, in particular with respect to a main extension parallel to each other orientable, in particular stackable. The storage space required by the at least two frame parts, in particular a volume of the smallest convex envelope, is thus substantially smaller than that of the at least two frame parts in the installed state. In particular, a pack size can be significantly reduced by the fact that the area spanned by the at least two frame parts in the installed state and extending parallel to the hob opening can be considerably reduced by the parallel alignment of the at least two frame parts in the transport state. The smaller dimensions of the arranged in the transport state at least two frame parts allow a particularly efficient stabilization of these by packaging material. The fact that the at least two frame parts in the transport state can be arranged close to each other, the individual frame parts can also mutually stabilize. Due to the multi-part design of the frame device, a cost-intensive production of an integrally formed frame device can be avoided. For example, raw material can be saved over a manufacturing process in which the frame device is completely separated from a single workpiece. Overall, the frame device according to the invention is thus particularly economical to produce and inexpensive and safe to transport.

Preferably, the frame device is designed such that the at least two frame parts can also be transferred from the installed state into the transport state. Advantageously, this achieves the result that the frame device can again be transferred into an easily transportable state. Such a frame device is particularly easy to handle, especially when moving or when purchasing a new kitchen worktop.

The frame device may be modular. By this is meant that, in particular with regard to their length and / or their cross-sectional area, different frame parts can be combined with each other. In this way, it is advantageously achieved that the frame device can have a hob recess with largely individually determinable dimensions by a combination of corresponding frame parts. The frame device is thus flexible adaptable to a variety of hobs with different dimensions.

The frame device preferably has at least three, in particular at least four, in particular at least five, in particular at least six, frame parts. More preferably, the frame device has exactly four frame parts. Here, the frame device may each have two in the installed state opposite frame parts of the same length. In a preferred embodiment, at least one of the frame parts is longer than another of the frame parts.

The at least two frame parts preferably comprise a metallic material, in particular stainless steel and / or aluminum, and / or a plastic, in particular a temperature-resistant plastic, in particular a plastic having a melting temperature of at least 120 ° C., and / or a mineral material, in particular ceramic, on. The at least two frame parts can be produced in a continuous process, in particular in an extrusion process or in a pultrusion process. For this purpose, the at least two frame parts preferably have a constant cross-section. Preferably, the cross section of the at least two frame parts is constant along their respective main extension. Preferably, all frame parts have the same cross-section. Alternatively, the at least two frame parts can also be produced in a casting process, in particular in an injection molding process.

The at least two frame parts can non-positively to transfer from the transport state in the installed state, in particular by means of a screw connection and / or a clamping connection, and / or materially, in particular by gluing, and / or form-fitting, in particular by nesting, and / or by latching together be connectable. Preferably, the at least two frame parts are at least partially positively connected to each other. For example, the at least two frame parts can be inserted into one another, wherein this connector can be secured by means of a screw connection and / or an adhesive bond.

The connection of the at least two frame parts in the installed state is preferably formed as a corner joint. The corner joint may be formed as a miter or as a butt joint. According to a preferred embodiment, the corner joint is formed as a butt joint, wherein a short side of a first frame part communicates with a long side of a second frame part and wherein the second frame part does not extend completely along the short side of the first frame part in the installed state. In the region of the corner connection can be present a concave recess between the frame parts. The connection of the at least two frame parts can also be arranged in a straight region or in a curved region of the frame device.

Preferably, the frame device is rectangular in plan view. In particular, the frame device may be square in plan view. The frame device can also be circular or non-circular, in particular oval, in plan view.

According to one aspect of the invention, the at least two frame parts are straight along a main extension. The at least two frame parts are thus particularly economical to produce and very compact packable and storable. In a preferred embodiment, the at least two frame parts can be shortened in their length. For this purpose, the at least two frame parts can have cut marks and / or predetermined breaking points and / or cross-sectional tapers. In the area of the cross-sectional tapers, the at least two frame parts can be particularly easily separable, in particular break off without tools. Such frame parts are particularly flexible adaptable to the dimensions of different hob systems.

Alternatively, the at least two frame parts can also be curved, in particular without corners.

According to a further aspect of the invention, the frame device comprises at least one frame connecting means, which is independently connectable with at least two of the frame parts for transferring the at least two frame parts from the transport state to the installed state. Preferably, the at least one frame connecting means with at least two, in particular with at least three, in particular with at least four frame parts connectable. The independent connection with the at least two frame parts is to be understood that the at least two frame parts can be attached to the at least one frame connecting means without an operative connection, in particular successively. The at least one frame connection means may be designed as a straight connector, corner connector, oblique connector or T-connector. Advantageously, this achieves the result that the connection between the at least two frame parts can be particularly simple. For example, the at least two frame parts can be inexpensively manufactured in a continuous process with a constant cross section, wherein the at least one frame connecting means ensures a simple transfer from the transport state to the installed state.

Preferably, at least one of the frame parts has a frame groove. The at least one frame connecting means may be formed such that it engages positively in the at least one frame groove. The frame groove is preferably formed in the at least one frame part along the entire longitudinal extent. The corresponding frame part is therefore particularly simple, in particular in a continuous process, manufacturable.

Preferably, the at least one frame connecting means comprises an overlap panel which covers a contact gap between the interconnected at least two frame parts. With such a diaphragm, the frame device may be optically particularly attractive. Alternatively, the at least two frame parts may have a ground contact surface which reduces the contact gap such that it is less than 0.1 mm, in particular less than 0.05 mm.

According to a further aspect of the invention, the at least two frame parts in the transport state can be arranged, in particular relative to one another, such that a smallest convex envelope of the at least two frame parts has a volume that is at least 50% lower, in particular at least 70%, in the transport state. lower, in particular at least 80% lower, in particular at least 90% lower, than in the installed state. Preferably, a dimension of the smallest convex envelope in at least one spatial direction in the transport state is at least 50% lower, in particular at least 70% lower, in particular at least 80% lower, in particular around at least 90% less than in the installed state. This advantageously achieves the result that the storage space required by the at least two frame parts in the transport state is substantially reduced compared with the storage space claimed in the installed state. The frame device can thus be transported in the transport state particularly simple, inexpensive and relatively robust against transport damage.

According to a further aspect of the invention, the at least two frame parts in the transport state are stackable in such a way that at least two frame part surfaces of in each case two adjacent frame parts abut one another flatly. Under the frame part surface is a surface of the at least one frame part to understand, which is limited by a change in curvature, in particular by an edge in its extension. Preferably, the two frame part surfaces of the respective frame part are at least partially oriented not parallel to each other. Advantageously, it is thereby achieved that the at least two frame parts can be stably stacked in the transport state. Slippage of the at least two frame parts against each other is inhibited.

Alternatively, the at least two frame surfaces of the respective frame part can also be oriented parallel to one another. This makes it possible in principle to stack the at least two frame parts even more compact.

According to a further aspect of the invention, the at least two frame parts delimit at least one further frame recess spaced and / or adjacent to the hob opening and / or the circumference. This is to be understood that the at least two frame parts in addition to the hob recess completely enclose the frame recess. In the at least one frame recess, for example, at least one further hob and / or at least one extractor device and / or a control device can be used. Preferably, the at least two frame parts in the manner of a modular system can be combined. Thus, depending on the frame connection means used, the frame device may either surround only the hob recess or, moreover, limit at least one frame recess circumferentially. The frame device is therefore particularly flexible adaptable to different cooktop systems. The at least two frame parts can have a uniform or a different length and can be combined with different frame connecting means such that the frame device in the installed state encloses a different number of recesses, in particular with different dimensions.

According to a further aspect of the invention, the frame device comprises a plate connection device for fastening the at least two frame parts to a kitchen worktop and / or a hob connection device for connecting the at least two frame parts with at least one hob. Preferably, the plate connecting device each comprises a connection tab connected to the at least two frame parts and / or a plate web. The connecting plate and / or the plate web can be designed so that they rest on the kitchen worktop from above or can be attached to them from below. Preferably, the dimensions of the connecting plate and / or the plate web correspond to the dimensions of a plate groove introduced into the kitchen worktop. In this way it can be achieved that an upper side of the frame device can be arranged flush with an upper side of the kitchen worktop. Preferably, the plate connecting device has an adhesive for material connection to the kitchen worktop.

The cooktop connecting device can each have at least one connecting strap connected to the at least two frame parts and / or at least one cooktop bar. The at least one hob can be connectable to the frame device via the connection tab and / or the hob web. In particular, the at least one hob can be supported from above on a plate support surface of the at least one hob web. Preferably, the hob connection device has an adhesive for the material connection of the at least two frame parts with the at least one hob. The at least one hob is thus particularly easy to connect to the frame device.

According to a further aspect of the invention, the frame device comprises the hob connection device with a field support surface for supporting the at least one hob and the plate connection device with a plate support surface for support on the kitchen worktop. The frame device is thus designed as a mounting frame. By this is meant that the assembly of the at least one hob on the frame device on the kitchen worktop takes place. For this purpose, this is at least one hob on the frame device fastened and the frame device can be attached to the kitchen worktop. Preferably, the frame device is supported from above on the kitchen worktop. The at least one hob can be supported from above on the frame device.

The plate support surface can be arranged above the field support surface. Preferably, a distance between the plate support surface and the field support surface is at least 5 mm, in particular at least 10 mm, in particular at least 20 mm, in particular at least 40 mm. Advantageously, this achieves that an upper side of the at least one hob can be arranged offset relative to a top of the kitchen worktop down. The frame device thus ensures protection of these surrounding surfaces from overflow liquids. In addition, an upper surface of a cooking utensil used for heating cooking material can thereby be displaced downwards in use on the at least one hob. This top thus approaches the kitchen worktop. The operation of the corresponding hob system is thus particularly ergonomic.

According to one aspect of the invention, at least one of the frame parts may have a cross-sectional area varying along its longitudinal extension. The frame device may have, for example, pin-shaped and / or rib-shaped projections for positioning and / or carrying cookware.

According to a further aspect of the invention, at least one of the frame parts has a footprint for carrying cookware. The footprint can have a width, in particular transversely to its main extension, of at least 50 mm, in particular at least 75 mm, in particular at least 100 mm, in particular at least 150 mm, in particular at least 200 mm. Such a footprint protects the kitchen worktop advantageous against wear. In particular, heated cookware can thus be placed on the footprint instead of on a sensitive surface of the kitchen worktop.

Preferably, the at least one frame part has a plurality of shelves. These can be present for example separated by at least one recess. The at least one recess, the at least one frame part on one or both sides waisted.

Preferably, the at least one recess completely penetrates the at least one frame part, in particular in the vertical direction. The recess may be formed rectangular in cross-section and / or round. Advantageously, it is achieved that in the respective relevant areas for carrying cookware several shelves per frame part can be arranged.

According to a further aspect of the invention, the frame device has a sealing device for the liquid-tight attachment of the at least two frame parts to at least one hob and / or a kitchen worktop. The sealing device may have a sealing ring and / or a sealing band. Preferably, the sealing device between the at least two frame parts and the at least one hob and / or the kitchen worktop is arranged. The sealing device can be arranged, for example, in the region of the hob connection device and / or in the region of the plate connection device. The sealing device advantageously ensures that contaminants, in particular dust and / or liquids, can not penetrate between the at least two frame parts and the at least one hob and / or the kitchen worktop.

The frame device can be designed as a mounting frame or as a pure decorative frame. Trained as a decorative frame device is used in contrast to a trained as a mounting frame frame device only the visual enhancement and not for attachment of the at least one hob on the kitchen countertop. A wall thickness of the at least two frame parts of the frame device formed as a decorative frame is preferably less than 1 mm, in particular less than 0.7 mm, in particular less than 0.5 mm. According to an alternative embodiment, the wall thickness of the at least two frame parts can be up to 4 mm. The frame device is thus mechanically particularly stable.

Another object of the invention is to increase the range of use of a frame device.

This object is achieved by using the frame device as a mounting frame for attaching at least one hob to a kitchen worktop.

The frame device is preferably used so that it is visible from above after attaching the at least one hob on the kitchen worktop. The frame device preferably covers a gap between the at least one hob and the kitchen worktop. The frame device thus offers, together with the hob used in the kitchen worktop a particularly appealing appearance. By covering any gaps, the frame device ensures a particularly easy-to-clean and hygienic arrangement of the hob on the kitchen worktop.

Another object of the invention is to improve a hob system.

This object is achieved by a cooktop system with a frame device according to the preceding description and at least one cooktop arranged in the hob opening for heating cooking product. The at least one hob has at least one cooking place. The advantages of the hob system result from those of the frame device.

The hob system is preferably designed as a combination device. By this is meant that all components of the cooktop system, with the exception of the frame device, are integrally connected to each other at delivery. Such a hob system thus exists as a mounting unit. An assembly effort when installing the hob system in the kitchen worktop can thus be significantly reduced.

According to one aspect of the invention, the plate support surface and / or an upper side of the frame device is arranged above, in particular at least 5 mm above, in particular at least 10 mm above, in particular at least 50 mm above, in particular at least 100 mm above, an upper side of the at least one cooktop. An upper edge of the frame device is thus above an upper surface, in particular a highest-lying surface of the at least one hob over and prevents overflow of liquid over an edge of the hob system.

According to a preferred embodiment, the hob, in particular the cooking surface plate, projects beyond the frame device in a plan view at least in sections. For example, the hob can project beyond the frame device in its corner regions.

According to a further aspect of the invention, the hob system comprises at least one extraction device for the withdrawal of cooking fumes down. Preferably, at least one cooking vapor inlet opening is arranged in the at least one frame recess. The at least one Kochdunsteintrittsöffhung is preferably introduced into a cooking plate of the at least one hob. The at least one extraction device can thus be designed as hob extraction. Preferably, the cooking surface plate is formed as a glass-ceramic plate. Even more preferably, all of the cooking zones of the cooktop system have a common cooktop plate, in which the at least one Kochdunsteintrittsöffhung is introduced. Alternatively, the cooking vapor inlet opening can be formed by one of the frame parts.

Preferably, the frame device is designed to provide a corner protection and / or edge protection for the at least one hotplate plate. For this purpose, the frame device can enclose the edges and / or corners of the at least one hotplate plate. The at least two frame parts can for this purpose have a concave field support surface.

The following is based on the Fig. 1 to 3 a first embodiment of a hob system 1 for installation in a kitchen worktop 2 described. The hob system 1 is designed as a combination device. For this purpose, the hob system 1 combines four hobs 3 and a trigger device 4 in a single, preassembled device. The hobs 3 are arranged on a common cooking plate 5. The cooking surface plate 5 is designed as a glass-ceramic plate. The extraction device 4 has a Kochdunsteintrittsöffhung 6. The cooking vapor inlet opening 6 is formed as a centrally located, round inlet recess in the cooking surface plate 5. Above the cooking vapor inlet opening 6, a trigger grid 7 is arranged.

The hob system 1 has a user interface 8. The user interface 8 is integrated in the cooking surface plate 5. For detecting user inputs, the user interface 8 comprises touch-sensitive sensors 9. To output information, the user interface 8 has a screen 10.

The hob system 1 is arranged in a hob system recess 11 of the kitchen worktop 2. The hob system 1 is attached to the kitchen worktop 2 by means of a frame device 12.

The frame device 12 comprises four frame parts 13. Each of the frame parts 13 is straight along its respective main extension direction 14. The frame parts 13 each have a plurality of frame part surfaces 14a, 14b. The frame part surfaces 14a, 14b of the respective frame part 13 together form the lateral surface of the respective frame part 13. The front and the rear frame part 13 are identical and differ from the two lateral frame parts 13. The four frame parts 13 are made of a metallic material, in particular Stainless steel, made.

In the Fig. 1 to Fig. 3 the four frame parts 13 are connected to each other and thus shown in an installed state. For this purpose, between each two of the frame parts 13 frame connecting means 15 are arranged. Each of the frame parts 13 is attached to two frame connecting means 15. The four frame members 13 define a hob recess 16 forwardly, rearwardly and laterally. None of the individual frame parts 13 completely surrounds the hob opening 16.

The frame connecting means 15 each comprise a screw connection. The frame parts 13 are thus positively connected to each other in the installed state. The frame connection means 15 are at least partially positively arranged in a frame groove 32 of the two middle frame parts 13. The connection between the frame parts 13 is formed as a butt joint. Mutually contacting contact surfaces 17 of the butt joint are formed relative to one another such that a contact gap 18 between the respective frame parts 13 is less than 0.1 mm.

The connection between the frame parts 13 is detachable. The frame parts 13 can thus be transferred from the installed state into a transport state in which the frame parts 13 are present separately from one another. Each of the four frame parts 13 has a visible surface 19. The visible surfaces 19 are just trained. In the area of the visible surfaces 19, the frame parts 13 are brushed and thereby formed optically particularly attractive.

The frame device 12 has a hob connection device 20 for connecting the frame parts 13 to the cooking surface plate 5 of the four hobs 3. The cooktop connection device 20 comprises a cooktop web 21 with a field support surface 22. To connect the cooktops 3 to the frame device 12, these are located on the field support surfaces 22 via the cooktop plate 5. Depending on a heating electronics 23 of the hobs 3 is mounted on a common electronics housing 24 on an underside of the cooking surface plate 5.

The frame device 2 further comprises a plate connection device 25 for fixing the four frame parts 13 to the kitchen worktop 2. The plate connection device 25 comprises a plate web 26 with a plate support surface 27. The respective frame part 13 lies above the plate support surface 27 of the plate web 26 on the kitchen worktop 2 from above on.

To compensate for unevenness between the frame device 12 and the kitchen worktop 2, a compensating means 28 is arranged on the plate support surface 27. For uniform distribution of stress between the cooking surface plate 5 and the frame device 12, a compensating means 28 is arranged on the field support surface 22. The compensating means 28 are made of a soft elastic material. The compensating means 28 are adhesively bonded to the field support surface 22 or to the plate support surface 27. The arranged on the field support surface 22 compensating means 28 has a cooking surface plate 5 facing adhesive surface for material connection of the respective frame part 13 with the cooking surface plate 5. Likewise, the compensating means 28 arranged on the plate support surface 27 has an adhesive surface arranged on the side of the kitchen worktop 2 for connecting the respective frame part 13 to the kitchen worktop 2. Preferably, the compensation means 28 consist of a double-sided adhesive thick elastic tape.

The frame device 12 has a sealing device 29. The sealing device 29 is arranged between the respective frame parts 13 and an outer edge of the cooking surface plate 5. The sealing device 29 is designed such that between the frame device 12th and the hobs 3, in particular the cooking plate 5, no liquids can penetrate. An upper side of the sealing device 29 terminates flush with the respective upper side of the frame parts 13 and with the upper side of the hotplate plate 5. The sealing device 29 is designed as a circumferential sealing ring with a rectangular cross-section. The sealing ring may for example consist of silicone.

The two lateral frame parts 13 each have a footprint 30. The footprint 30 is flush with the surface of the cooking surface plate 5 and serves to carry cookware. The footprint 30 has a width B, transverse to the main extension 14 of the respective frame part 13, of 150 mm.

The operation of the hob system 1 is as follows:
For attaching the hob system 1 to the kitchen worktop 2, first the frame device 12 is inserted into the hob system recess 11 of the kitchen worktop 2. For this purpose, the frame parts 13 present separately in the transport state are transferred to the installed state and connected to one another. Two each present as a threaded sleeve with external thread frame connecting means 15 are thereby introduced into the front and the rear frame part 13. By means of each introduced into the frame connecting means 15 screw member 39, the mutually adjacent frame members 13 are connected to each other at their contact surfaces 17. The frame device 12 is inserted into the hob system recess 11 and as in Fig. 3 represented, sealingly glued over the compensating means 28 with the surface of the kitchen worktop 2.

In the surrounded by the frame parts 13 hob recess 16, the hobs 3 are used with the common cooking plate 5. The hobs 3 are connected via the cooking surface plate 5 with the frame device 12. For this purpose, the cooking surface plate 5 is supported on the field support surface 22 of the cooktop webs 21, and is glued to them via the compensating means 28. In the gap between an outer edge of the cooking surface plate 5 and the frame device 12, the sealing device 29 is introduced in the form of a sealing ring and seals them from each other liquid-tight.

Via the user interface 8, the power supplied to the hobs 3 and the exhaust device 4 can be controlled. Cookware is heated above the cooktops 3, thereby resulting cooking fumes are withdrawn from the trigger device 4.

In Fig. 4 a frame device 12 is shown according to a further embodiment. The frame device 12 according to the Fig. 4 differs from the already explained embodiment in that each of the frame parts 13 has a footprint 30. The width B of the respective footprint 30 is 120 mm. All of the four frame parts 13 have an identical cross section, transverse to their main extension 14, on. The four frame parts 13 are in particular cut off from a bar-shaped semifinished product. In Fig. 4 the four frame parts are shown in the installed state. The four frame parts 13 each have a miter cut 31 on both sides. The miter cuts 31 of the frame parts 13 abut each other at the corners of the frame device 12. Between each two frame parts 13, the frame connecting means 15 is arranged. The frame connecting means 15 engages positively in a frame groove 32 of the respective frame part 13.
