Description

The present invention relates to a panel system for a cooking appliance and a cooking appliance with such a panel system.

In the prior art, such. Am DE 10 2016 218 807 A1 , a distinction is made between two different systems of panels for cooking appliances. These two systems include, on the one hand, a so-called self-supporting switch front and, on the other hand, a so-called sandwich construction.

In the self-supporting switch front, a base part is provided, which can be made of different materials, such. As steel or stainless steel. This base can be brushed or painted. Positioning and attachment options are integrated into this base part as interfaces to the cooking appliance. The base part also contains various fastening options for design and control parts, such as screw holes, fastening straps, etc. However, the design freedom is limited with the self-supporting switch front. You can e.g. B. are usually only used for fixed switch handles, as there are rarely opportunities for a hidden attachment with retractable switch handles. Accordingly, additional process steps, such as B. welding or gluing, necessary if additional elements are to be attached to the base part.

The sandwich structure is regularly used in higher-quality devices. As a rule, these have higher design requirements, such as the use of retractable switch handles. In the case of the sandwich structure, the design part--this means the panel visible to a user of the cooking appliance--usually made of stainless steel, painted steel, glass or plastic, is bonded to a carrier part using double-sided adhesive tape. The carrier part is also referred to as a panel carrier. The fascia support accommodates all the required components using various fastening elements. This can e.g. B. screw points, cupboard and bending straps, snap hooks, eyelets, etc. These fasteners ensure clean positioning and secure attachment to the cooking appliance. In order to be able to compensate for the different coefficients of thermal expansion of the different materials, the double-sided adhesive tape is relatively thick. On the one hand, this leads to higher costs and, on the other hand, increases the tolerances. Instead of double-sided adhesive tape, it is also known from the prior art to use wet adhesive. With the help of the wet glue, individual components, such as e.g. B. glass panes, touch foils, holding elements, such as the panel carrier, or electronics housing, glued to the design part.

The object of the present invention is to provide an improved panel system for a cooking appliance.

According to a first aspect, a panel system for a cooking appliance is provided. The screen system comprises at least a first and a second connecting means, a self-supporting screen and at least one attachment. When the panel system is mounted on the cooking appliance, the panel conceals the user's view of the at least one first and second connection means. The add-on part is attached to the panel with the aid of the at least one first and second connecting means. The first connecting means holds the at least one attachment in a linearly displaceable and/or pivotable manner between at least a first and a second position. The second connecting means is set up to fix the attachment in its first and/or second position.

In comparison to the known sandwich structure, the present solution makes it possible to save at least two components, namely firstly the screen carrier and secondly the double adhesive tape. This saves costs and improves tolerances. Furthermore, the gluing process is no longer necessary and further processing without curing time, such as with wet gluing, is made possible. In addition, the relatively complex assembly process step of gluing is saved.

At the same time, such a panel system allows a high degree of design freedom. In particular, so many variants can be easily created, because the at least one attachment can - be linearly displaced or pivoted between one and a second position - depending on the design requirement. For example, if a new cooking appliance design by the manufacturer requires at least one attachment to be moved a bit in a linear direction, i.e. to be repositioned, this can be done according to the panel system proposed here simply by the attachment being attached to the second (new) in the manufacturer's assembly plant ) position is fixed (in contrast to the first - earlier - position). If, for example, the position of an attachment in the form of a retractable rotary knob is changed, only the position of the hole in the panel needs to be changed. The lanyards required to hold the rotary toggle are already in place because they - inherently - allow linear translation and allow attachment to the second (new) position.

The same applies to the variant that the attachment can be pivoted between a first or second position. In particular, it can be provided that the attachment is positioned in the first position and then pivoted into the second position. Assembly can advantageously be simplified as a result.

The linear displacement can advantageously also be combined with the pivoting. This results in a particularly flexible assembly.

Overall, many identical interfaces can be provided with the proposed panel system, and the use of many identical parts is also made possible. Furthermore, such a screen system can be produced with simple means. Individual assemblies can be exchanged quickly and easily. Furthermore, a high level of recyclability is guaranteed, since the panel system can be dismantled quickly and easily.

A "self-supporting panel" (here also referred to as a self-supporting switch front) is to be understood as meaning a panel which, firstly, has an outside that is directly visible when installed in the cooking appliance, and secondly, is stiff enough to accommodate one or more attachments, which are used in particular to control the cooking appliance are needed to carry. These include user interfaces, such as switch handles, clocks, displays, buttons, indicator lamps, etc. In addition, the panel can also carry other attachments, for example those for fastening and positioning on the body of the cooking appliance. The panel or its outer side (here also referred to as “front side”) preferably has symbols relating to the operating state of the cooking appliance. The symbols can be glued, printed or engraved on the bezel.

The "user" here means the person who uses the cooking appliance for its intended purpose, i.e. cooking, boiling, roasting or baking, etc. The user is also referred to as the operator person.

“Fixing” here means that the attachment is held immovably in six degrees of freedom in the first and/or second position. In particular, the fixing can also include a previous positioning of the add-on part.

The panel can be made of different materials, such as steel or stainless steel (especially brushed or painted) or plastic.

The first and/or second connecting means are preferably set up to connect the at least one add-on part to the panel in a detachable manner. One or more first and/or second connecting means can be provided.

According to one embodiment, the panel has a visible front side that faces the user when the panel system is in the installed state and a rear side that faces away from the user, the rear side having the at least one first and second connecting means.

Advantageously, for the user standing in front of the cooking appliance when it is being used as intended (in the kitchen), the at least one first and second connecting means are not visible. A smooth, closed surface of the panel can thus be provided on the front side. This is also advantageous with regard to the entry of dirt into the cooking appliance.

According to a further embodiment, the linear displaceability of the at least one add-on part in a width direction of the cooking appliance is provided when the panel system is in the assembled state.

"In a width direction of the cooking appliance in the mounted state of the panel system" is to be understood here as meaning that the attachment is linearly displaceable in a direction that corresponds to the width direction of the cooking appliance when the panel system is mounted on the cooking appliance. When the panel system is mounted on the cooking appliance, the add-on part can no longer be moved but is fixedly mounted by means of the first and second connecting means. In the case of cooking appliances, it is often a requirement to adapt the design in such a way that control elements, such as rotary toggles, are offset in the width direction, in order to enable a new or different appliance type, for example. The present development meets this requirement in a simple manner.

According to a further embodiment, the at least one add-on part can be pivoted about an axis in the width direction of the cooking appliance when the panel system is in the installed state.

"In a width direction of the cooking appliance in the installed state of the panel system" is to be understood here as meaning that the attachment can be pivoted about an axis which corresponds to the width direction of the cooking appliance when the panel system is installed on the cooking appliance. When the panel system is mounted on the cooking appliance, the add-on part can no longer be pivoted, but is fixedly mounted by means of the first and second connecting means. As a result, for example, the at least one attachment can be positioned in a simple manner in its first position and then pivoted into its (final) second position. In embodiments, the attachment is not fixed in its first position, but is fixed in its second (final) position.

According to a further embodiment, the at least one first and second connecting means fix the at least one add-on part at opposite ends of the panel for stiffening the same.

The at least one attachment thus bridges the screen from the first to the second connecting means. Such a "bridge" advantageously leads to the desired stiffening of the panel. As a result, the panel itself can advantageously be manufactured from a less rigid, in particular less thick, material. Accordingly, material can be saved.

According to a further embodiment, the ends in the vertical direction of the cooking appliance are opposite one another when the panel system is in the assembled state.

The ends are preferably formed by the opposite long sides of the screen. The long sides are advantageously bridged or firmly coupled to one another with the aid of the at least one add-on part, thereby stiffening the screen.

According to a further embodiment, the at least one attachment can be extended in one direction in order to bring it into engagement with the at least one first and/or second connecting means.

Depending on the type of add-on part, the assembly of the at least one add-on part may require that it be moved exactly perpendicular to the main plane of extension of the panel. This can be necessary, for example, when assembling a rotary toggle, in particular a pot or a switch mount for such a rotary toggle. In this case, it can be advantageous to first position the at least one add-on part on the panel and then, in a second step, to fix it. This can advantageously be done by extending the add-on part in a direction parallel to the main plane of extension of the panel. The bringing into engagement here means a form-fitting connection of the at least one add-on part to the first and/or second connection means.

According to a further embodiment, the at least one add-on part can be extended in the vertical direction of the cooking appliance when the panel system is in the installed state.

According to a further embodiment, the at least one first and/or second connecting means is formed in one piece with the panel.

Advantageously, the first and/or second connecting means is a geometry that is formed on the panel and is set up to bring about a form fit of the at least one add-on part with the panel in at least one degree of freedom, preferably in two or three degrees of freedom. The fact that the first and/or second connecting means is manufactured in one piece with the panel results in a simple manufacturing process for the panel system.

According to a further embodiment, the panel has a main plane of extent, the at least first and/or second connecting means being bent out of the main plane of extent.

Such a screen can be manufactured in a simple manner, in particular as a tool-off-the-shelf part.

According to a further embodiment, the at least one first connecting means is in the form of a rail, in particular a double edging of the panel. In addition or as an alternative, the at least one second connecting means can be designed as a simple edging of the panel and/or locking strap.

In very general terms, the first and second connecting means can be designed as tabs for screwing, clinching, setting, or as cut edges or snap hooks. In particular, the second connecting means can also be designed as a rail and optionally also have the tabs, cut edges or snap hooks described here. A rail is advantageous in that it allows thermal expansion of the at least one add-on part, that is to say it is in particular mounted in a floating manner along the rail. Advantageously, the different thermal expansion coefficients of the different materials used for the screen system have little or no effect on its quality. Furthermore, the assembly described here using rails etc. allows for easy assembly without complicated tools or systems. A double edging also protects the panel system and/or the cooking appliance from the ingress of liquid. Additional components can be omitted. In general, the present solution makes it possible to completely or partially dispense with welded-in holding elements. Preferably is the at least one attachment can thus be replaced easily and non-destructively, for example by customer service or a remanufacturer. Last but not least, the connection technology described here results in good recyclability, because the panel system can be easily dismantled into its individual parts and the raw materials can be separated from one another. This is different with the solutions known from the prior art (double-sided adhesive tape or wet bonding).

According to a further embodiment, the panel has the first connecting means, in particular the rail, at its upper end in the vertical direction, and the second connecting means, in particular the simple folded edge and/or the sling strap, at its lower end in the vertical direction. The vertical direction here refers to the assembled state of the screen system.

In particular, several locking tabs are provided. In their folded state, these can secure or fix the first and/or second position of the at least one add-on part. For example, a first folding strap is provided which, in its folded state, fixes the first position of the at least one add-on part. Furthermore, a second folding strap is provided which, in its folded state, fixes the second position of the at least one add-on part. The rail or the double edge could also be arranged at the lower end of the panel. Generally speaking, the first connecting means can also be attached to the lower end of the panel and the second connecting means to the upper end thereof.

According to a further embodiment, the at least one add-on part is a display device, in particular a display, an operating element, in particular a switch or a switch holder, for example a holder for a retractable rotary knob, a positioning device for positioning the panel in relation to a body of the cooking appliance, a communication device, in particular a WLAN module, a loudspeaker device and/or an end piece for closing the panel in the width direction of the cooking appliance when the panel system is in the installed state.

Furthermore, the at least one attachment can be a steam module or a steam hinge. These devices are preferably provided if the cooking appliance has a device for generating steam for the cooking process. The steam module includes in particular a controller for the device mentioned above. The steam hinge is a hinge for this device.

According to a further embodiment, the end piece has the positioning device.

As a result, two components are advantageously integrated into one: First, the end piece closes the panel on one side. Secondly, the end piece with the positioning device ensures that the panel is positioned on the cooking appliance or on an appliance body of the cooking appliance. In particular, the positioning device can be set up to position the panel opposite or on pilaster strips of the device body.

According to a second aspect, a (further) screen system for a cooking appliance is provided. The panel system includes a self-supporting panel and at least one attachment. At its upper end, based on its installed state in the cooking appliance, the panel has a double edge with a horizontal section and an adjoining vertical section. The vertical section points down. The at least one attachment is attached to the panel using the double edging. In particular, the at least one add-on part is provided in a linearly displaceable manner in the double edge.

The double edging advantageously offers protection against overflowing water.

According to a third aspect, a cooking appliance, in particular a cooker or oven, is provided with one of the panel systems described above.

In this case, the panel system is mounted on a device body, in particular on pilaster strips of the same.

According to one embodiment of the cooking appliance, this has a metal sheet which engages under the double edge. This means that the sheet metal reaches into the volume defined by the double edge from below. The sheet metal is, for example, a switch compartment cover. Instead of the metal sheet, a plastic part (also, for example, in the form of a switch compartment cover) could also be provided, which engages under the double edge.

The sheet metal or the plastic part preferably forms a gap at its free end with the horizontal section of the double folded edge or with the at least one add-on part. The gap is preferably used for ventilation. The gap is advantageously protected from overflowing water. Furthermore, the sheet metal or the plastic part itself can be designed without ventilation openings, which saves costs.

The features explained in relation to the first aspect apply accordingly to the other aspects, and vice versa.

Further possible implementations of the invention also include combinations of features or embodiments described above or below with regard to the exemplary embodiments that are not explicitly mentioned. The person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the invention.

In the figures, the same reference symbols denote the same elements or elements with the same function.

1 shows a cooking appliance 1 in a perspective view. The cooking appliance 1, which is an oven according to the exemplary embodiment, comprises a panel system 2 and a body 3. The panel system 2 is attached to the body 3 in a manner that will be described in more detail later. In particular, the body 3 can only have schematically indicated pilaster strips 4 (only one of which is shown).

The cooking appliance 1 includes a door 5 at the front. The door 5 can be opened in order to provide access to a cooking chamber inside the cooking appliance 1 . A self-supporting screen 6 of the screen system 2 is arranged above the door 5 . The panel system 2 also has, for example, two rotary toggles 7 that can be lowered. The rotary toggles 7 can each be adjusted between a first and a second position. In the first position, as in 1 shown, the rotary toggle 7 over the panel 6 to the front, ie in the depth direction T over. In this first position, they can be operated by a user standing in front of the cooking appliance 1 . For example, the temperature in the cooking chamber can be adjusted in this way. In the second position, they are sunk into the panel 6, that is to say they are arranged essentially flush with the panel 6 with their front side. Symbols 8 can be provided around a respective rotary knob 7 which, together with a marking 9 on the respective rotary knob, indicate information about an operating state of the cooking appliance 1 . The symbols 8 can be printed, glued or embossed onto the panel 6, for example. Furthermore, the symbols 8 can be provided by electronic devices such as LEDs. The symbols 8 are provided directly on the side 10 visible to the user (here also referred to as the front side) of the panel 6 . The panel system 2 also includes a display 11. The display 11, which can in particular also be a touch display, is set up to display information about the cooking appliance 1 and/or the food to be cooked therein.

The 2 shows the aperture 6 off 1 in a perspective rear view. The back of the panel 6 is denoted by 12 there. As in synopsis with 1 to recognize, the panel 6 has a main extension plane E, which is in the assembled state of the panel system 2 in the vertical direction H (see also 1 ) and in the width direction B (see also 1 ) of the cooking appliance 1 extends.

A first connecting means 13 and a plurality of second connecting means 14, 15, 16 connecting means are provided on the panel 6. In this case, the first connecting means 13 according to the exemplary embodiment is designed as a rail. The rail 13 is produced by folding the sheet metal from which the panel 6 is made twice. The sheet metal can be, for example, a steel or stainless steel sheet. Alternatively, the screen 6 can also be made of plastic. In this case, the panel 6 together with the double edge is produced as an injection molded part. The rail 13 extends along an upper longitudinal side 17 of the panel 6 provided in the vertical direction H.

A simple folded edge is provided as the second connecting means 14 , which extends along the lower longitudinal side 18 of the panel 6 in relation to the vertical direction H. Like the double edging 13 , the simple edging is manufactured in one piece with the panel 6 . The simple folded edge 14, like the double folded edge 13, is made from the sheet metal blank (or by injection molding) used to manufacture the panel 6, namely by bending out of the main plane of extension E. While the simple folded edge 14 extends perpendicularly to the main plane of extension E, the double edging 13 comprises two sections 19, 20. The first section 19 also extends perpendicularly to the main plane of extension E. The section 20, which is in turn folded over compared to section 19, extends in a plane parallel to the main plane of extension E.

The second connecting element 15 is designed in the form of a plurality of locking straps. The folding tabs 15 can be formed in the material of the simple folded edge 14 . 2 shows the uncrossed state of the locking tabs 15.

Furthermore, the second connecting means comprise counter-holders 16 for holding end pieces 21 (see FIG 3 ), as will be explained in more detail later.

Furthermore shows 2 Through holes 22 for the rotary knob 7 and a right-angled recess 23 for the display 11. The recess 23 can also be round, oval, etc.

To fix the panel 6 in the width direction B on the body 3 (see 1 ) tabs 24, for example, can be provided on the lower long side 18, with the help of which the panel 6 can be connected to the body 3 or the pilaster strips 4 (see also 1 ) is screwed. The positioning of the panel 6 on the body 3 in the vertical direction H and the vertical direction T (see also 1 ) takes place via the end pieces 21, which act as positioning devices, as will be explained in more detail later.

3 shows the view 2 . In addition to the end piece 21 already mentioned 3 furthermore, a switch receptacle 25 for receiving one of the rotary knobs 7 in its retracted position and the display 11 in its installed state.

Based on 4 until 7 the following is a montage of the in 3 shown end piece 21 on the panel 6 explained in more detail. The same applies to an in 3 not shown right-side end piece 21. The end pieces 21 cover in their assembled state, as in 3 shown, a cross-section 26 defined by the screen 6 and the connecting means 13, 14 (see 2 ) partially and thereby ensure a gap-free closure with the body 3 in the width direction B viewed on the side of the cooking appliance 1 (see 1 ).

4 shows a perspective front view of the end piece 21, 5 a corresponding reverse view. 6 shows a position of the end piece 21 shortly before it is inserted laterally into the cross section 26. 7 shows a first position I of the end piece 21. In position I, the end piece 21 is attached to the panel 6. On the upper side, the end piece 21 has a geometry 27 which is held in the rail 13 in a displaceable manner. On the underside, the end piece 21 has a geometry 28 with which it rests against the simple edging 14 in the vertical direction. Furthermore, the geometry 28 includes a snap hook 29 which snaps behind the counter-holder 16 . As a result, displacement of the end piece 21 in the linear direction along the width direction B relative to the panel 6 is blocked. In interaction with the geometry 27, the end piece 21 is fixed in all six degrees of freedom. In addition, the end piece 21 connects the rail 13 to the simple folded edge 14 (bridging function), so that the end piece 21 stiffens the panel 6 .

A second position II of the end piece 21 is in 7 indicated schematically. Due to the design of the first connecting element 13 as a rail and the second connecting element as a simple folded edge 14, the end piece 21 can be moved to a new linear position II in the event of a design change by simply redesigning (in particular the counter-holder 16) the panel 6 a high degree of design flexibility.

As also in the 5 until 7 shown, the end piece 21 includes positioning aids 30, which are designed to position the panel 6 on the body 3 or the pilaster strips 4 of the cooking appliance 1 in the depth direction T and in the vertical direction H. The positioning devices 30 are advantageously designed as crosses and can—like the geometries 27 and 28—be designed in one piece with the end piece 21 . The aforementioned components of the end piece 21 are advantageously formed as a one-piece plastic injection-molded component.

The 8th until 10 illustrate the structure and function of related 3 mentioned switch holder 25. 8th shows their individual parts. These comprise a two-piece housing with housing parts 31, 32 which can be clipped together. Furthermore, a holding element 34 can be fastened in a linearly displaceable manner in the vertical direction H on a web 33 of the housing part 31 that projects upwards (vertical direction H). 9 shows the retracted condition (or also available as "delivery condition"). The holding element 34 is on a snap hook 35 (see 8th ) snapped at web 33. In the in the 3 and 10 In the assembled state shown, the holding element 34 is moved upwards in the vertical direction H, whereby it disengages from the snap hook 35 and is in its end position (see FIG 10 ) locked. The snap hook 35 snaps behind an end section 36 of the holding element 34 and thus secures its extended position (here also “extended state”).

The 11 until 14 now illustrate the installation of the switch mount 25 on the panel 6. For this purpose, the switch mount 25 is in a line - in 11 indicated by the arrow 37 - perpendicular to the diaphragm plane E (see 3 ) moves, exclusively in this direction. After the switch mount 25 is positioned against the panel 6 (see 12 ), the holding element 34 is moved upwards in the direction shown (see arrow, corresponds to vertical direction H). As a result, the holding element 34 engages with the rail 13, see 13 ). Subsequently, as in 14 shown, one of the cupboard tabs 15 is bent upwards (in the vertical direction H). As a result, the locking tab 15 locks the lower end 38 of the switch receptacle 25 from moving out of the simple folded edge 14. Accordingly, the switch receptacle 25 is in the in 14 shown state fixed in six degrees of freedom. This corresponds to one in 14 shown first position I of the switch receptacle 25.

Also in 3 this first position is denoted by I. From the synopsis of 3 and 14 it can be seen that the switch holder 25 can also be attached to any other position, for example on one in 3 second position, designated II, could be moved. According to the exemplary embodiment, this is done by a linear displacement of the switch mount 25 in the rail and along the simple edging 14. The switch mount 25 can just as easily be locked or fixed at position II. This is done in the same way as at position I. However, in this case the through hole 22 (see 2 ) should also be provided at a linearly different position. However, this is easy to implement in terms of design or in the construction and development process of the panel system 2 .

15 shows the display 11 in a perspective front view, 16 in a corresponding rear view. Based on 17 until 19 the assembly of the display 11 on the panel 6 is explained below. As in 17 As can be seen, the display 11 with a T-shaped geometry 39 is inserted into the rail 13 at its upper end in the vertical direction H. This corresponds to a first position I of the display 11. The display 11 is then pivoted about an axis 40, which runs in the width direction B, as indicated by the arrow in FIG 17 implied. As a result, the lower end 41 of the display 11 is pivoted into the panel 6 . The lower end 41 comes into contact with the lip 14. The corresponding second position II is in the 18 and 19 shown where in 19 one of the locking tabs 15 is bent or twisted upwards in the vertical direction H. This secures the lower end 41 in the second position II. In particular, the folding strap 15 engages in an 16 counter-contour 42 shown on the lower side of the display 11 a. As a result, the display 11 is secured in all six degrees of freedom in its second position II.

A synopsis of 3 and 19 shows that the display 11 could be linearly shifted to a different position, with only the recess 23 ( 2 ) would have to be moved constructively, which is easily possible. The sash 15 would also have to be moved or a (different) sash 15' already present in the design (see 2 ) be used.

The connecting elements 13, 14, 15, 16 described here are advantageously all arranged on the rear side 12 of the panel 6, so that they are not visible to a user who is operating the cooking appliance 1 as intended. In addition, as in 1 to see a smooth closed surface of the aperture 6.

Basically, the installation of the attachments 11, 21, 25 described here by hand or done automatically. Instead of or in addition to the connecting means 13 to 16 described here, non-detachable types of connection, for example clinching, can also be used. Additional add-on parts can be a WLAN module, a sound module or the like.

20 shows another embodiment of a cooking appliance 1, which is that of the 1 until 19 largely corresponds. In the following, the existing differences are mainly discussed.

A metal sheet 43 is mounted on the body 3 side. The sheet metal 43 is, for example, part of a switch compartment cover and forms an upper housing part of the cooking appliance 1. The sheet metal 43 protrudes from below into a volume 45 at its free end 44 (edge perpendicular to the plane of the paper or in the width direction B). The volume 45 is defined by the rail or double edge 13 together with the screen 6 . The free end 44 of the metal sheet 43 engages behind the vertical section 20 of the double folded edge 13 in the horizontal direction (depth direction T). The vertical section 20 connects to the horizontal section 19 of the double edge 13 down.

Furthermore, the free end 44 of the metal sheet 43 preferably forms a gap 46 with the horizontal section 19 of the double flange 13 and/or, as in FIG 20 shown, with the (upper) geometry 39 of the display 11. A ventilation of a volume 47 defined between the sheet metal 43 and the screen system 2 can take place by means of the gap 46. Correspondingly, the metal sheet 43 can advantageously be designed without ventilation openings. Because of its arrangement, the gap 46 is protected from overflowing water 48, which can penetrate through a gap 49 between the body 3 and the screen system 2, in particular a corner area 50 of the double edge 13.

Although the present invention has been described using preferred exemplary embodiments, it can be modified in many ways.
