Description

The invention relates to a cooking appliance comprising a housing and a door pivotably arranged on the housing about a pivot axis for closing a cooking chamber of the appliance from the front. At least one cable is routed from the housing into the door, wherein the at least one cable is arranged in a receiving space that is at least partially limited by a cable protection element and is movable relative to the cable protection element as a result of the opening and closing of the door.

The DE 10 2016 124 070 A1 This describes a cooking appliance according to the preamble of claim 1, in which an appliance door is pivotally attached to the appliance housing by means of two hinge fittings. A connecting device, attached to the appliance housing, is arranged between the two hinge fittings, through which an electrical cable is routed from one hinge fitting to the other. In the area of one of the hinge fittings, a feedthrough part, rigidly connected to a hinge housing of the hinge fitting, is arranged, through which the electrical cable leading out of the appliance housing is routed to the connecting device.

The WO 2017/178366 A1 This describes an oven with one door, in which a cable for connecting an electrical unit to the oven's control unit is routed along the door frame. In the area between the door frame and the oven housing, the cable runs through a cable channel positioned at a distance from a door hinge.

A disadvantage here is that the cable channel is disruptive when the door is open, especially with regard to accessing the space between the open door and the oven housing, for example for cleaning purposes.

Furthermore, the JP H01189422 A a microwave oven in which a protective element for a cable is rotatable about a pivot axis on a hinge pin of a The hinge is positioned for a microwave oven door. When the door is opened, the protective element that holds the cable pivots together with the door around the hinge pin, which extends upwards along the door.

In this regard, it is particularly disadvantageous that the protective element, which can be pivoted together with the door, takes up an undesirably large amount of installation space in the area of the door hinge.

The object of the present invention is to create a cooking appliance of the type mentioned above in which the routing of the lines is improved.

This problem is solved by a cooking appliance with the features of claim 1. Advantageous embodiments with expedient further developments of the invention are specified in the dependent claims and in the following description.

The cooking appliance according to the invention comprises, among other things, a housing and a door pivotably arranged on the housing about a pivot axis for closing a cooking chamber of the cooking appliance from the front. At least one cable of the cooking appliance is routed from the housing into the door. The cooking appliance includes a cable protection element, wherein the at least one cable is arranged in a receiving space that is at least partially delimited by the cable protection element. The at least one cable is movable relative to the cable protection element as a result of the opening and closing of the door. The cable protection element is arranged on a hinge base of a hinge of the cooking appliance, wherein the hinge base and the cable protection element remain stationary when the door is opened and closed.

Accordingly, when the door is opened and closed, at least one cable moves along the receiving space, which is at least partially bounded by the cable protection element. The cable protection element, which runs along the hinge body, provides a guide for this movement of the at least one cable. This improved cable guidance, in particular, prevents damage to the at least one line is subjected to an undesirably high point bending load or an undesirably strong torsional load.

According to the invention, the receiving space for the at least one cable has a cable outlet in an end region furthest from the door. Such an arrangement of the cable outlet allows for favorable cable routing.

Furthermore, according to the invention, at least one cable has an arc-shaped profile in at least one section extending from the cable outlet to a strain relief element on the device side. By providing such an arc, which is formed by the section of the at least one cable, a cable length sufficient to allow the at least one cable to move along the receiving space when the door is opened and closed can be provided very easily.

Furthermore, according to the invention, at least one cable is routed from the cable protection element to a strain relief element on the door side, wherein the strain relief element on the door side is arranged on a first pane of the door. This reliably ensures that no undesirable strain is applied to the at least one cable in the area of the first pane, which is designed in particular as the front pane of the door, when the door is opened and closed.

Furthermore, according to the invention, the at least one cable has a length extending from the strain relief element on the appliance side to the strain relief element on the door side, which limits the amount of time a user of the cooking appliance can pull the at least one cable out of its compartment to a predetermined extent. The length of the at least one cable between the two strain relief elements is also preferably dimensioned such that movement of the at least one cable relative to the cable protection element is permitted when the door is opened and closed.

Nevertheless, the length should preferably not be so great that the user of the cooking appliance can pull the cable relatively far out of the cooking chamber. This is also important with regard to avoiding undue stress on at least one of the components. The design is advantageous, particularly in preventing at least one cable from being pinched when the door is closed.

In particular, the predetermined amount can be specified as being between approximately 10 millimeters and 20 millimeters, for example, approximately 15 millimeters. This reliably prevents the formation of an undesirable loop or kink in the area of the at least one cable accessible when the door is open. This is also advantageous with regard to the long-term functionality of the at least one cable.

Furthermore, the risk of unwanted kinking of the at least one cable as a result of opening and closing the door can be easily avoided because the at least one cable is merely moved back and forth within the receiving space during opening and closing. This direction of movement of the at least one cable coincides, in particular, with a longitudinal direction of the receiving space, which in turn corresponds to a longitudinal direction of the hinge body, with the hinge allowing or enabling the pivoting movement of the door about the pivot axis. The door can be held by a hinge leaf of the hinge, which is pivotable relative to the hinge body about the pivot axis.

Furthermore, this cable routing allows for a relatively large bending radius for at least one cable. This is particularly advantageous if the cable is relatively rigid or stiff due to a protective covering or sheathing.

Furthermore, a very simple cable routing design is advantageously achieved. And the free path length of the at least one cable, which is required to allow movement of the at least one cable due to the opening and closing of the door, can be kept particularly short. This also contributes to a high level of protection for the at least one cable.

The improved cable routing is also advantageous because it allows for the permanent and reliable transmission of electrical energy and/or data to corresponding devices or consumers located in the door via at least one cable. This ensures the long-term functionality of at least one cable.

Furthermore, by routing the at least one cable along the hinge base through the receiving space, good protection against unauthorized pulling out of the at least one cable or unauthorized tightening of the at least one cable can be achieved very easily.

Furthermore, the routing of the at least one cable along the hinge base body, on which the at least one cable is well hidden or concealed by the cable protection element, is advantageously very inconspicuous.

Furthermore, undisturbed cleaning of the cooking appliance is possible in the area of the swivel axis because at least one pipe in this area is located very close to the hinge of the cooking appliance. In particular, this ensures that a drip tray or drain channel integrated into the cooking appliance is and remains easily accessible for cleaning by a user of the cooking appliance.

Finally, sufficient space can be provided in the receiving area to route the at least one cable, preferably protected by a sheath such as a braided covering, along the hinge body through the receiving area. Such a protective sheath is particularly advantageous with regard to a reliable electrical connection from the cooking appliance to the door.

The improved routing advantageously ensures that even after a high number of folding cycles, during which the door is opened and Since the device is pivoted around the pivot axis for closing, no failure of at least one line occurs.

Preferably, the cable protection element limits the receiving space for the at least one cable towards a flange component of the cooking appliance, the flange component being adjacent to a loading opening of the cooking chamber. This advantageously prevents the cable protection element from coming into contact with the flange component of the cooking appliance, which may become hot during operation, particularly as a cooking oven.

The flange component can be designed to extend around the loading opening of the cooking chamber, so that the flange component forms, in particular, an oven flange to which a muffle is connected in the depth direction of the cooking appliance in a manner known per se, the walls of which define the cooking chamber of the cooking appliance. Such a design of the flange component contributes to a simplified construction of the cooking appliance.

Preferably, an end section near the door of a wall of the cable protection element, which at least partially delimits the intake space, extends beyond the flange component in the depth direction of the cooking appliance towards the door. This ensures that at least one cable or line reliably prevents contact with the flange component.

Preferably, the cable protection element is fixed to an outer surface of the hinge body, with the receiving space for the at least one cable being partially limited by the outer surface of the hinge body. This results in a particularly small space requirement for the cable protection element. Furthermore, this is advantageous with regard to mounting the cable protection element to the hinge body.

In particular, if the hinge base extends in the depth direction of the cooking appliance, a corresponding movement of at least one line, coinciding with the depth direction of the cooking appliance, can be observed when opening and closing the door. within the recording space. Such a translational movement of the at least one conduit when opening and closing the door is particularly advantageous with regard to avoiding stress on the at least one conduit, in particular avoiding bending stress.

Preferably, the cable element has at least one fastening element by means of which the cable protection element is fixed to the hinge base. This allows for very simple installation of the cable protection element when attaching it to the hinge base. This applies in particular if the at least one fastening element is formed integrally with a base body of the cable protection element.

The at least one fastening element can be designed as a latching element and/or a locking element, and in particular can comprise both a locking element and a latching element. For example, the locking element, which in particular enables a bayonet locking mechanism, can provide a secure and reliable fixation of the cable protection element to the hinge base, especially one designed to absorb major forces. During assembly, the latching element then engages with the hinge base for final fixation. For example, the latching element can be designed as a snap hook that engages in a corresponding receptacle formed in the hinge base, such as a screw hole. Such fastening elements are advantageous for simple and quick mounting of the cable protection element to the hinge base.

Preferably, the cable protection element has at least one stop element which, in a mounting position of the cable protection element, engages in a receptacle formed on the hinge base. Such a stop element advantageously limits movement during mounting the cable protection element to the hinge base, namely by ensuring that the mounting position of the cable protection element is reached when the stop element engages in the receptacle. Such an engagement of the stop element against a wall of the hinge base that defines the receptacle ensures a advantageous, in particular tactile feedback to a person involved in mounting the cable protection element to the hinge base.

In addition to or as an alternative to the engagement of the stop element in the receptacle, the stop element may include a locking element which, in the mounting position of the cable protection element, engages behind a wall of the hinge base. Such engagement of the locking element behind the wall of the hinge base is also advantageously easily felt and/or heard by the person mounting the cable protection element to the hinge base.

Preferably, at least one stop element is formed integrally with a base body of the conductor protection element. This is particularly simple and requires little effort.

For example, the cable outlet can be located on the upper side of the cable protection element. This allows for the simple definition of a desired further, especially curved, path for at least one cable within the area of the receiving space.

Additionally or alternatively, the cable outlet can be located at the end of the cable protection element furthest from the door. This is also advantageous with regard to routing the at least one cable, thereby largely avoiding undesirable stresses, in particular bending stresses, on the at least one cable when the door is opened and closed.

The strain relief element on the appliance side can be arranged, in particular, on the housing of the cooking appliance, for example on a side wall element or support element of the cooking appliance in the form of a pilaster. In this way, a particularly unobtrusive routing of the at least one cable along the housing is achieved.

Preferably, at least one line is guided through a passage opening on the door-side strain relief element, which is formed in the first pane. This allows for the advantageous supply of at least one component of the cooking appliance in an area of the door adjacent to the front of the first pane of glass via at least one line.

Preferably, a modular attachment is arranged on one front side of the first pane. This modular attachment comprises a further pane spaced apart from the first pane. When the door is closed, this further pane is positioned further away from the cooking chamber than the first pane. This allows components of the modular attachment to be supplied with power via the same line.

Preferably, the modular attachment forms a handle for opening the door. The handle provided by such a large-area modular attachment can advantageously be used to effect the movement of the door around its pivot axis when opening the door, by the user of the cooking appliance applying a pulling force to the modular attachment forming the handle.

The modular attachment, in particular a frame of the modular attachment positioned between the second pane and the first pane, can provide a recessed grip into which the user can grasp to open the door. This is advantageous for easy operation when opening the door.

Preferably, electrical energy can be supplied via at least one conductor to at least one component of the module attachment located in the space between the first and second discs. For example, at least one light source of the module attachment can be supplied with electrical energy so that the light source can emit light during operation. This makes it very easy to implement lighting, especially ambient lighting, using the module attachment.

Additionally or alternatively, at least one conductor can include an electrical conductor designed for grounding at least one component of the module attachment. This is advantageous with regard to electrical safety during operation of the module attachment.

Additionally or alternatively, data can be supplied via at least one line to at least one component of the module attachment located in the space between the first disk and the next disk. Accordingly, the at least one line can additionally or alternatively be configured as a data line and/or comprise at least one data line. Consequently, control commands can be supplied to a corresponding component of the module attachment, such as control commands to activate a light source of the module attachment, for example, a light-emitting diode.

With regard to such functionalities of the at least one line, the improved line routing is advantageous because damage to the at least one line is easily and reliably avoided through this line routing.

Preferably, the strain relief element on the door side has a plurality of centering arms which bear against a wall provided by the first pane that circumferentially delimits the passage opening. Such centering arms facilitate, firstly, the attachment of the strain relief element to the first pane in the area of the passage opening. Furthermore, the centering arms protect the at least one cable. This is because the centering arms at least contribute to preventing contact between the at least one cable and the wall delimiting the passage opening.

Preferably, at least one of the centering arms has a crimp rib. In particular, at least one crimp rib can be formed on each of the centering arms. Such ribs deform plastically when the strain relief element is attached to the door, during which the centering arms are inserted into the opening, thus ensuring a particularly secure hold of the strain relief element in the opening formed in the first pane.

Additionally or alternatively, the door-side strain relief element may have at least one locking arm which includes a locking section that rests against the front of the first pane. Providing such a locking arm allows for reliable and easy installation of the implement a door-side strain relief element in the area of the passage opening, which is formed in the first pane.

Furthermore, the locking section of the at least one locking arm, which engages behind the first pane and rests against its front surface, ensures a secure and very robust fixation of the door-side strain relief element to the first pane. Additionally, the engagement of the at least one locking arm when engaging behind the first pane is advantageously perceptible and/or audible to an installer attaching the door-side strain relief element to the first pane.

This applies in particular if the at least one locking arm of the door-side strain relief element is spring-loaded and thus engages behind the first disc after passing through the opening, with the locking section of the at least one locking arm coming into contact with the front of the first disc.

Preferably, the strain relief element on the door side comprises a channel section extending towards the cable protection element, in which the at least one cable is arranged. Thus, on the one hand, the at least one cable is protected by the channel section in the area of the first pane of the door. Furthermore, the channel section advantageously defines the direction along which the at least one cable should extend towards the cable protection element. This is advantageous with regard to improved cable routing.

Preferably, a plurality of ribs that clamp the at least one cable are arranged on opposite side walls of the channel section. This makes it particularly easy to prevent movement of the at least one cable in the area of the strain relief element when the door is opened or closed.

Preferably, the side walls of the channel section rest with their narrow sides against an inner side of the first disc. This results in a very simple construction of the channel section extending towards the pipe protection element, so that so that at least one cable can be easily and quickly inserted into the channel section during installation.

Preferably, the door-side strain relief element has a support plate that rests against an inner surface of the first pane. This is also advantageous with regard to ensuring the door-side strain relief element is securely positioned on the first pane of the door. The support plate can be formed integrally with the base body of the strain relief element. This is particularly cost-effective.

Preferably, the door-side strain relief element can be fixed to the first pane by means of a fastening element that passes through a fastening eye formed in the support plate. This allows for a particularly secure fixation of the door-side strain relief element to the first pane by inserting the fastening element, for example, a screw, into the fastening eye. In this case, the door-side strain relief element is fixed to the first pane by means of the fastening element. However, it is also possible for the support plate to have the fastening eye, but for the fastening eye to remain essentially unused. In particular, the fastening element can be passed through the fastening eye and tightened to fix the door-side strain relief element to the first pane.

Preferably, the at least one cable has a protective sheath. This largely prevents damage to the at least one cable, for example, when the at least one cable, together with the protective sheath, moves relative to the stationary hinge base and the stationary cable protection element during the opening and closing of the door. In particular, the protective sheath can comprise a braid. This provides particularly reliable protection for the at least one cable.

In particular, the protective sheath comprising a braid makes it possible to achieve a relatively rigid structure in a way that advantageously includes at least one conductor and the sheath, roughly in the form of a cable. This is also achieved in the This is advantageous because it largely prevents damage to at least one line due to bending stress.

Additionally or alternatively, at least one cable can have a sheath made of a sliding material. This allows for very low-friction movement of the sheathed cable along the receiving space when the door is opened and closed.

Preferably, the sliding material is designed to be resistant to the temperatures occurring during operation of the cooking appliance, for example, by using a tetrafluoroethylene-hexafluoropropylene copolymer, also known as fluoroethylene propylene (FEP). A sheath made of such a material not only ensures particularly high sliding properties of the sheathed cable along the cable protection element in the receiving space, but also good resistance to extremely high temperatures, such as those that can occur during operation of the cooking appliance. This is advantageous.

Terms such as "top", "bottom", "front", "back", "horizontal", "vertical", "depth direction", "latitude direction", "height direction" and the like indicate the positions and orientations that would be present when the cooking appliance is used and arranged as intended, and when viewed from the perspective of an observer standing in front of the cooking appliance and looking towards it.

In the figures, identical or functionally equivalent elements are provided with the same reference symbols.

In Fig. 1 A schematic perspective view shows a cooking appliance 1. The cooking appliance 1 comprises a housing 2 with a muffle 3. The walls of the muffle 3 define a cooking chamber 4 of the cooking appliance 1. The cooking appliance 1 also includes a door 5, which is movable, in this case pivotable about a pivot axis A, and is attached to the housing 2. The cooking chamber 4 can be closed from the front by means of the door 5 when the door 5 is moved into a closed position. Fig. 1 Door 5 is shown in a partially open position.

In Fig. 1 Furthermore, a coordinate system illustrates a transverse direction x or width direction of the cooking appliance 1, a depth direction y of the cooking appliance 1, and a vertical direction z of the cooking appliance. When the door 5 is closed, the door 5 accordingly extends essentially in a plane spanned by the vertical direction z and the transverse direction x or width direction. This orientation of the door 5 is shown in Fig. 2 shown, in which door 5 can be seen in a front view.

In particular, from a combination of Fig. 2 with Fig. 3 It is evident that the door 5 has a first pane, which in this case is designed as the front pane 6 of the door 5. Furthermore, the door 5 has a module attachment 7, which is arranged on a front side 8 of the front pane 6. The module attachment 7 comprises a further pane 9 or a projecting pane 9, which is spaced apart from the front pane 6 in the depth direction y.

In Fig. 3 The door 5 is shown in its installed position, i.e., when the door 5 is attached to the housing 2 of the cooking appliance 1 (compare Fig. 1 Furthermore, door 5 is in Fig. 3 The door 5 is shown in its closed position. In this closed position, the front glass 6 is closer to the cooking chamber 4 of the cooking appliance 1 than the other glass 9. Consequently, a gap is formed between the front glass 6 and the other glass 9.

Within this gap, a recessed handle 11 is provided by a frame 10 of the module attachment 7, into which a user can grasp to open the door 5 from the Fig. 3 to move the closed position shown to an open position. In other words, to open the door 5, the user can apply a pulling force to a large-area handle element of the door 5 provided by the module attachment 7, and in particular pivot or swing the door 5 open about the pivot axis A. For this purpose, in the exemplary embodiment of the door 5 shown here, the module attachment 7, or rather the handle element formed by the module attachment 7, has the recessed handle 11. Therefore, in this case, a handle with a pull bar or the like is not required to open the door 5, as is the case, for example, with the following: Fig. 2 as is evident.

Door 5 comprises a plurality of door profiles in a manner known per se, wherein of these door profiles in Fig. 3 An example of a side door profile 12 is shown, on the front of which the front glass 6 is arranged. Furthermore, in a manner known per se, the front glass 6, viewed in the depth direction y of the cooking appliance 1, can be a front glass of a glass pack of the door 5, wherein such a glass pack can comprise a plurality of glass successive in the depth direction y.

From a synthesis of Fig. 2 with Fig. 3 It is particularly evident that the front window 6 has larger dimensions in the vertical direction z and in the transverse direction x than the further window 9 placed in front of it, which belongs to the module attachment 7.

In Fig. 3 The recessed handle 11 provided by the frame 10 of the module attachment 7 is shown only in a lower, hinge-adjacent area of the door 5. In fact, this recessed handle 11 runs circumferentially along the frame 10, which in this case comprises four frame elements. In the exemplary embodiment of the module attachment 7 shown, these frame elements are designed as four profile parts 13, 14 (see figure). Fig. 2 ).

In the present case, the frame 10 comprises two profile parts 13 extending in the transverse direction x in the installation position of the door 5 when the door 5 is closed, in the form of a Fig. 2 upper profile part 13 and one in Fig. 2 lower profile part 13. Furthermore, the frame 10 comprises two profile parts 14 extending vertically in the z direction when the door 5 is closed, in the form of a Fig. 2 left profile part 14 and one in Fig. 2 right profile part 14.

Furthermore, the module attachment 7 has light sources, not shown in detail here, for example in the form of light-emitting diodes, which, when in operation, i.e. when supplied with electrical energy, couple light into the respective light guides 15 of the module attachment 7, wherein in Fig. 3 Only two of these light guides 15 are visible. The light coupled out of the light guides 15 during operation of the light sources strikes inclined viewing surfaces 16 of a frame element 17 designed in the manner of a passe-partout, which is in Fig. 2 can be seen in a front view.

These viewing surfaces 16, which in the exemplary embodiment are inclined from the further disc 9 towards the front disc 6 (compare Fig. 3 ) are visible to an observer looking through the front pane 9 towards the windscreen 6. The viewing surfaces 16 can be illuminated with light released or coupled from the light guides 15, with each of the four light guides 15 extending along one of the profile sections 13, 14 (compare Fig. 2 ) extends.

In particular for the purpose of supplying the light sources with electrical energy, the cooking appliance 1 has at least one line 18, the course or routing of which leads from the housing 2 of the cooking appliance 1 or from the housing 2 into the door 5 in Fig. 3 is illustrated schematically. Fig. 3 For the sake of clarity, only one conductor 18 is shown, whereby the at least one conductor 18 laid in the door 5 can be designed to conduct electrical current and/or as a data line and/or as a protective conductor providing grounding or the like. In particular, the conductor 18 laid in the door 5 can be configured to carry electrical current and/or as a data line and/or as a protective conductor providing grounding or the like. Fig. 3 The exemplary line 18 shown is designed in the manner of a cable bundle, which comprises a plurality of conductors and/or data lines formed from a respective electrically conductive material.

Thus, via at least one line 18, current and/or data can preferably be permanently and safely routed into the door 5 of the cooking appliance 1, which is designed in particular as an oven, in order to provide the electrical current and/or the data for corresponding consumers or components, which in particular belong to the module attachment 7.

Out of Fig. 3 It is evident that the line 18 extends into a gap formed between the front window 6 and the further window 9, or rather the in front of it. This gap is sealed off from the surroundings by means of a Fig. 3 Sealed by the sealing element 19 shown in part.

In Fig. 3 Furthermore, a line 20 indicates the approximate position of a Fig. 3 For the sake of clarity, the inner pane of door 5 is not shown. Accordingly, when door 5 is closed, this inner pane rests against a flange component, which is located in Fig. 3 shown in part, and which in this case is designed as an oven flange 22 surrounding a loading opening 21 of the cooking chamber 4. Fig. 4 The furnace flange 22, which surrounds the loading opening 21, is shown in a front view. When the door 5 is closed, the inner pane of the door 5 rests against this furnace flange 22 or against a seal provided in the area of the furnace flange 22.

To pivot door 5 around pivot axis A (compare Fig. 1 ) the cooking appliance 1 has two hinges 23, one of which faces each other in the transverse direction x of the Cooking appliance 1 opposite hinges 23 approximately in Fig. 4 This is shown. For example, from a compilation of Fig. 4 with Fig. 5 , but also from Fig. 6 It is evident that the respective hinge 23 comprises a cuboid and elongated hinge base 24, which extends along the depth direction y of the cooking appliance 1. Furthermore, the hinge 23 comprises a hinge blade 25, which extends in the vertical direction z of the cooking appliance 1 when the door 5 is closed (compare Fig. 4 ) and at which door 5 is located.

The hinge base body 24 of the respective hinge 23 is fixed to a housing component of the housing 2, the housing component being designed in this case as a pilaster 26 of the cooking appliance 1. The pilaster 26, designed in the manner of a side wall element or lateral support element of the cooking appliance 1, is in Fig. 4 shown in a front view and in Fig. 3 a partial view in a side view. In addition to the hinge base body 24, the oven flange 22 is attached to the pilaster 26.

In particular, from a synthesis of Fig. 5 with Fig. 6 It is evident that a cable protection element, in this case designed as a cable duct 28 or cable shaft, is arranged on an outer side 27 of the hinge base body 24, which laterally delimits a receiving space 29 in which the at least one cable 18 is arranged. From the in Fig. 7 The perspective view of the cable duct 28 shown shows a possible course of the recording space 29 along the depth direction y of the cooking appliance 1.

In particular, the cable duct 28 comprises a wall 30 having a U-profile in cross-section, which delimits the receiving space 29 in the transverse direction x of the cooking appliance 1. The cable or line 18 is protected within the receiving space 29. Fig. 3 In this regard, the course of line 18 through cable duct 28 is shown, although line 18, which is concealed by wall 30, is in Fig. 3 It is not actually visible throughout.

In particular, from a synthesis of Fig. 3 with Fig. 5 It is evident that the wall 30 delimits the receiving space 29 for the cable 18 towards the furnace flange 22. The cable duct 28 serves as an insertion aid during the installation of the cable 18. This prevents contact between the line 18 or the cable and the sometimes hot oven flange 22.

The receiving space 29, which is bounded on one side by the wall 30 of the cable duct 28, also serves as a guide rail when operating the cooking appliance, namely when opening and closing the door 5. This is because the movement of the cable 18 along the receiving space 29, which extends in the depth direction y of the cooking appliance 1, is made possible by the cable duct 28, which serves as a guide or guide rail.

Movements of the cable or line 18 relative to the hinge base body 24 and the cable protection element in the form of the cable duct 28 attached to the hinge base body 24 are in Fig. 3 This is illustrated by a double arrow 31. During these movements of the line 18, which are caused by the opening and closing of the door 5, the hinge base body 24 and the line protection element in the form of the cable duct 28 shown here as an example remain stationary.

Especially from Fig. 3 combined with Fig. 5 It is evident that an end region 32 of the wall 30 near the door projects beyond the oven flange 22 in the depth direction y of the cooking appliance 1 towards the door 5. In this way, it is particularly reliably prevented that at least one line 18 comes into contact with the oven flange 22.

Out of Fig. 3 It is further evident that a passage opening 33 is formed in the front window 6, through which the cable or line 18 enters the space formed between the front side 8 of the front window 6 and the further window 9 or the attached window 9.

In the area of this passage opening 33, the line 18 is held by a strain relief element 34, which is prospectively located in Fig. 10 is shown and which in Fig. 3 This is recognizable in the state when mounted on the front glass 6. This door-side strain relief element 34 comprises a channel section 35 extending towards the hinge 23 or towards the cable duct 28 and thus, when the door 5 is closed, in the vertical direction z of the cooking appliance 1. This channel section 35 ensures that the line 18 is aligned towards the pivot axis A of the door 5, which is designed as a hinged door or oven door. From the pivot axis A, the line 18 is guided via an arc-shaped section to the end region 32 of the wall 30 and thus to an end region or an entrance opening of the receiving chamber 29 near the door.

The cable protection element in the form of the cable duct 28, which is attached to the hinge 23 in the present case, is advantageously provided in place of a cable chain or cable hose or the like.

The cable 18 advantageously has, firstly, a protective sheath (not shown in detail here), for example, formed as a braid or comprising a braid. Due to this braided sheath, the cable 18 is comparatively rigid. Furthermore, the cable 18 preferably has a sheath 36 made of a sliding material, which is preferably made of a material resistant to the temperatures occurring during operation of the cooking appliance 1. Because of this sheath 36, the comparatively rigid cable or line 18 is nevertheless very lubricated, so that the cable 18 can move very freely along the receiving space 29. The corresponding movement is in Fig. 1 illustrated by the double arrow 31.

In a rear area of the cable duct 28, the cable 18 is guided in a U-shaped arc 37 towards a device-side strain relief element 38, which is located in Fig. 3 The diagram is shown only schematically and not with regard to its actual structural design. In this case, this device-side strain relief element 38 is attached to the pilaster 26.

At the in Fig. 3 In the illustrated embodiment of the cable duct 28, the receiving chamber 29 has a cable outlet 39 in an end area furthest from the door, which is arranged or formed on an upper side of the cable duct 28 (compare Fig. 6 Accordingly, in this configuration of the cable duct 28, the arc 37 already begins in the area of the recording room 29.

At the in Fig. 9 In contrast, in the variant of the cable duct 28 shown, the cable outlet 39 is located at an end of the cable duct 28 furthest from the door. Accordingly, in this configuration of the cable duct 28, the cable 18 is laid over a greater length along a section of the receiving space 29, which extends in the depth direction y of the cooking appliance 1.

In both variants, it is preferably provided that the length of the cable 18, and in particular the bend 37, extending from the strain relief element 38 on the appliance side to the strain relief element 34 on the door side, is sufficient to allow the relative movements of the cable 18 caused by opening and closing the door 5 in the form of pivoting the door 5 about the pivot axis A. Preferably, this length is further dimensioned such that the amount of cable 18 pulled out of the receiving space 29 by a user of the cooking appliance 1 is limited to a predetermined amount.

In particular, it may be provided that the user or customer has no possibility of pulling the line 18 out of the receiving space 29 by more than approximately 15 millimeters. This ensures that, especially in the area of the swivel axis A (compare Fig. 1 ) of door 5 and thus does not unintentionally form a loop or kink in the line 18 in an area accessible when door 5 is open.

Especially from Fig. 3 combined with Fig. 5 It is further evident that, due to the routing of the pipe 18 very close to the hinge 23, it is ensured that the drainage channel 40 formed by the oven flange 22 remains easily accessible for cleaning. Consequently, the pipe 18 does not interfere with the corresponding cleaning process.

In particular, from a synthesis of Fig. 6 with Fig. 7 It is evident that the receiving space 29, bounded by the wall 30 of the cable duct 28, is preferably bounded on one side opposite the wall 30 in the transverse direction x of the cooking appliance 1 by the outer side 27 of the hinge base body 24. Based on Fig. 7 and from Fig. 8 A possible connection or fixing of the cable duct 28 to the outside 27 of the hinge base body 24 can be explained.

Accordingly, the cable duct 28 has a locking element 41, preferably formed integrally with a base body of the cable duct 28, which in this case functions as a bayonet locking element. Accordingly, two locking pins 42 project perpendicularly from a shaft 42 of the locking element 41, which, when the cable duct 28 is attached to the hinge base body 24, interact with a corresponding receptacle (not shown in detail here) to achieve the bayonet locking mechanism.

In this case, the locking element 41, which absorbs the main forces in the assembled state of the cable duct 28, is arranged in an end region of the cable duct 28 near the door. At an opposite end region of the cable duct 28, a snap-hook-type latching element 44 is arranged as a fastening element. This latching element projects from a wall 45 of the cable duct 28 extending in the vertical direction z of the cooking appliance 1 towards the hinge base 24. When the cable duct 28 is mounted to the hinge base 24, this snap-hook 44 engages in a corresponding receiving opening, approximately in the form of a screw hole, after the locking element 41, which in this case functions as a bayonet lock, is engaged.

Furthermore, the cable duct 28 has a stop element 46 arranged on its underside, which in Fig. 8 which is easier to see. The stop element 46 serves as an end stop to assist in mounting the cable duct 28 to the hinge base 24. The stop element 46 can engage in a corresponding receptacle formed on the hinge base 24. Furthermore, the stop element 46 can be used, as shown here, in Fig. 8 shown to have a locking lug 47 or similar locking element which engages a wall 59 of the hinge base body 24 (compare Fig. 8 ).

In Fig. 10 A first variant of the door-side strain relief element 34 is shown in a perspective view. Accordingly, the strain relief element 34 has a collar 48 which, when the strain relief element 34 is mounted to the windshield 6, rests against an inner surface 49 of the windshield 6 (compare Fig. 3 Furthermore, narrow sides of opposing side walls 50 of the canal section lie 35 on this inside 49 of the windshield 6. From Fig. 10 It is further evident that a plurality of ribs 51, which clamp the conductor 18, protrude from these side walls 50, between which the conductor 18 is clamped.

Furthermore, the door-side strain relief element 34 has a passage through the opening 33 in the front window 6 (compare Fig. 3 The area passing through the opening 33 is provided by a plurality of centering arms 52, with three centering arms 52 being provided in this case, spaced evenly apart from one another in the circumferential direction of the opening 33. On their outer sides, the centering arms 52 may have respective compression ribs 53, which, in the installed state of the strain relief element 34, bear against a wall that circumferentially delimits the opening 33 and is provided by the front panel 6. These centering arms 52, as well as, in the example shown, two locking arms 54, serve as jamb protection for the passage of the cable 18 through the front panel 6, which in this case is made of glass.

The preferably spring-loaded locking arms 54 each have a locking section 55 designed in the manner of a locking lug, wherein the locking sections 55 of the locking arms 54 bear against the front side 8 of the windscreen 6 when the door-side strain relief element 34 is mounted on the windscreen 6.

In Fig. 13 A second variant of the door-side strain relief element 34 is shown, in which a support plate 56 is formed integrally with a base body of the strain relief element 34, and which in this case has a mounting eye 57. A screw (not shown) can be passed through the mounting eye 57 of this support plate 56 or screw plate to securely fix the door-side strain relief element 34 to the front window 6.

First, the section of the strain relief element 34 comprising the locking arms 54 and the centering arms 52 can be clipped into the through-opening 33. Then, for a particularly robust fixing of the door-side strain relief element 34, the strain relief element 34 can be screwed to the front window 6 in the area of the support plate 56.

During the Fig. 13 In the variant of the strain relief element 34 shown, two support walls 58 are formed, which extend from the support plate 56, located on the inside 49 of the windshield 6, to one of the side walls 50 of the channel section 35. These support walls 58 increase the stability of the support plate 56.
