Description

Technical Field

[0001] The present invention relates to a cooking appliance having a housing and a door arranged on the housing in a manner capable of pivoting about a pivot axis, the door for enclosing the cooking chamber of the cooking appliance from the front. At least one wire is laid from the housing into the door, wherein the at least one wire is arranged in a receiving chamber at least partially demarcated by a wire protection element and is movable relative to the wire protection element due to the opening and closing of the door. Background Technology

[0002] WO 2017 / 178366 A1 describes an oven with a door, wherein cables for connecting the oven's electrical unit to a control unit are laid along the door frame. In the region between the door frame and the oven's housing, the cables extend through cable channels arranged spaced apart from the door hinges.

[0003] Here, the following should be considered as a disadvantage: the cable channel is interfered with when the door is open, especially with respect to the accessibility of the gap between the open door of the oven and the housing, for example, for cleaning purposes.

[0004] Furthermore, JP H01189422 A describes a microwave oven in which a protective element for a wire is arranged on a hinge bolt of a door hinge in a manner rotatable about an axis of rotation. When the door is opened, the protective element for receiving the wire deflects together with the door about a hinge bolt extending along the height direction of the door.

[0005] In this regard, it is particularly disadvantageous that the protective element, which can deflect with the door, unintentionally occupies a significant amount of structural space in the area of ​​the door's hinges. Summary of the Invention

[0006] The objective of this invention is to provide a cooking appliance of the type mentioned at the beginning, wherein the wire guide has been improved.

[0007] This task is accomplished using a cooking appliance. Advantageous embodiments of the invention, along with suitable improvements, are described in the following description.

[0008] The cooking appliance according to the invention includes a housing and a door arranged on the housing in a manner pivotable about a pivot axis, the door for closing a cooking chamber of the cooking appliance from the front. At least one wire of the cooking appliance is laid from the housing into the door. The cooking appliance includes a wire protection element, wherein the at least one wire is arranged in a receiving chamber at least partially defined by the wire protection element. The at least one wire is movable relative to the wire protection element due to opening and closing the door. The wire protection element is arranged on the hinge base of a hinge of the cooking appliance, wherein the hinge base and the wire protection element remain in a fixed position when the door is opened and closed.

[0009] Therefore, the at least one conductor moves along the receiving chamber, which is at least partially limited by a conductor protection element, when the door is opened and when the door is closed. This conductor protection element, extending along the hinge base, provides guidance for this movement of the at least one conductor. This improved conductor guidance, in particular, prevents undesirable high point-to-point bending loads or undesirable strong torsional loads from acting on the at least one conductor.

[0010] Furthermore, the risk of unintended bending of the at least one conductor due to opening and closing the door can be easily avoided, as the at least one conductor merely moves back and forth within the receiving chamber during opening and closing. This direction of movement of the at least one conductor coincides in particular with the longitudinal extension direction of the receiving chamber, which in turn corresponds to the longitudinal extension direction of the hinge base, wherein the hinge allows or enables pivoting movement of the door about a pivot axis. Here, the door can be held on the hinge strut (Scharnierschwert), which is capable of deflecting relative to the hinge base about the pivot axis.

[0011] Furthermore, this conductor guide allows for a considerably large bending radius of the at least one conductor. This is particularly advantageous when the conductor is constructed to be quite rigid or bend-resistant due to protective wrapping or sheathing.

[0012] Furthermore, the conductor guide section is constructed in a very simple manner in an advantageous way. It also allows for a particularly small free displacement length of the at least one conductor, which is set to allow for movement of the at least one conductor due to opening and closing. This is also beneficial for high protection of the at least one conductor, or rather, such a cable.

[0013] Furthermore, the improved conductor guide is advantageous in that it can reliably and persistently transmit, for example, electrical energy and / or data to a corresponding receiver or load arranged in a door via the at least one conductor. This is because the long-term, continuous functional reliability of the at least one conductor or cable is consistently guaranteed.

[0014] Furthermore, when at least one conductor is laid in a manner that guides it through the receiving chamber along the hinge base, good protection can be easily achieved to prevent the at least one conductor from being pulled out or dragged haphazardly.

[0015] Furthermore, the at least one wire is laid along the hinge base in an advantageously inconspicuous manner, and the at least one wire is arranged on the hinge base in a well-hidden or concealed manner by a wire protection element.

[0016] Furthermore, the cooking appliance can be cleaned undisturbed in the area of ​​the pivot axis because the at least one guide wire is arranged very close to the hinge of the cooking appliance in this area. In particular, this ensures that the drip trays or drain channels constructed on the cooking appliance are well accessible or remain accessible so that cleaning can be performed by the user of the cooking appliance.

[0017] Finally, sufficient space is provided within the receiving chamber to allow at least one wire, preferably with a protective sheath, such as a braided sheath, to be laid along the hinge base through the receiving chamber. Such a protective sheath is particularly advantageous for a safe electrical transition from cooking appliances to doors.

[0018] Advantageously, the improved wire guide can prevent the failure of at least one wire, even after a high number of flip cycles, as the door deflects about the pivot axis for opening and closing.

[0019] Preferably, the wire protection element defines a receiving chamber for at least one wire toward the flange member of the cooking appliance, wherein the flange member is adjacent to the filling port of the cooking chamber. Thus, the wire protection element advantageously prevents at least one wire, or cable, from coming into contact with the flange member of the cooking appliance, which may sometimes be hot due to the operation of the cooking appliance, especially if it is configured as an oven.

[0020] The flange member can be configured to surround the loading port of the cooking chamber, thereby forming, in particular, a furnace flange. The muffle furnace is connected to the furnace flange along the depth direction of the cooking appliance in a known manner, and the walls of the muffle furnace define the cooking chamber of the cooking appliance. This design of the flange member is beneficial for simplifying the construction of the cooking appliance.

[0021] Preferably, the end region of the wall near the door of the preferred conductor protection element, which at least partially encloses the receiving chamber, protrudes beyond the flange member along the depth direction of the cooking appliance. This reliably prevents the at least one conductor, or cable, from contacting the flange member.

[0022] Preferably, the wire protection element is fixed to the outer surface of the hinge base, wherein the receiving chamber for at least one wire is regionally defined by the outer surface of the hinge base. This results in a particularly small spatial requirement, or structural space requirement, for the wire protection element. Furthermore, this is advantageous in terms of the mounting of the wire protection element on the hinge base.

[0023] In particular, if the hinge base extends along the depth direction of the cooking appliance, a corresponding movement of the at least one conductor within the receiving chamber, coinciding with the depth direction of the cooking appliance, can be achieved when opening and closing the door. Such translational movement of the at least one conductor during opening and closing is particularly advantageous in terms of avoiding loads on the at least one conductor, especially in terms of avoiding bending loads.

[0024] Preferably, the wire protection element has at least one fastening element by means of which the wire protection element is fixed to the hinge base. This allows for very convenient installation of the wire protection element when it is placed on the hinge base. This is particularly applicable when the at least one fastening element is integrally formed with the base of the wire protection element.

[0025] The at least one fastening element can be configured as a locking element and / or as a locking member, and in particular includes not only a locking member but also a locking element. For example, a good and reliable fixed state of the wire protection element on the hinge base, particularly constructed to withstand major forces, can be established by means of a locking member, particularly achieving a bayonet-type locking. For final fixation, the locking element is subsequently locked together with the hinge base during installation. For example, the locking element can be configured as a hook that engages with a corresponding receiving portion formed in the hinge base, such as in the form of a screw hole. Such a fastening element is advantageous for the simple and quick installation of the wire protection element on the hinge base.

[0026] Preferably, the wire protection element has at least one stop element that is embedded in a receiving portion formed on the hinge base in the mounting position of the wire protection element. This stop element advantageously restricts movement when the wire protection element is mounted onto the hinge base, i.e., as the stop element is embedded into the receiving portion to reach the mounting position of the wire protection element. This stop of the stop element on the wall of the limiting receiving portion of the hinge base provides advantageous, and particularly perceptible, feedback to the person performing the installation work of the wire protection element on the hinge base.

[0027] As a supplement or alternative to the embedding of the stop element toward the receiving portion, it can be specified that the stop element includes a locking element that engages rearward with the wall of the hinge base in the mounting position of the wire protection element. This engagement of the locking element behind the wall of the hinge base is advantageously felt and / or heard by a person performing the installation work of the wire protection element on the hinge base.

[0028] Preferably, the at least one stop element is integrally formed with the base of the conductor protection element. This is particularly simple and convenient.

[0029] Preferably, the receiving chamber for at least one wire has a wire outlet in the end region of the receiving chamber away from the door. This arrangement of the wire outlet enables an advantageous wire guide.

[0030] For example, the wire outlet can be arranged on the upper side of the wire protection element. Thus, the desired, particularly curved, additional orientation of the at least one wire can be easily predetermined in the area of ​​the receiving chamber.

[0031] As a supplementary or alternative solution, the wire outlet can be located at the end of the wire protection element away from the door. This is also advantageous in terms of the wire guide portion of the at least one wire, by which unwanted loads, especially bending loads, on the at least one wire can be largely avoided when the door is opened and closed.

[0032] Preferably, the at least one conductor has an arcuate orientation in at least one section extending from the conductor outlet to the tension relief element on the appliance side. This arcuate arrangement, where the section of the at least one conductor forms the arc, easily provides the conductor length that should be provided for the mobility of the at least one conductor along the receiving chamber during opening and closing.

[0033] The tension-relieving element on the appliance side can be arranged, in particular, on the housing of the cooking appliance, such as on the edge-shaped sidewall element or support element of the cooking appliance. In this way, the at least one wire can be laid along the housing with particularly little interference.

[0034] Preferably, the at least one conductor is laid from the conductor protection element to the tension relief element on the door side, wherein the tension relief element on the door side is arranged on the first window panel of the door. Thus, it can be reliably achieved that no undesirable tension is applied to at least one conductor during opening and closing in the area of ​​the first window panel, which is particularly formed as the front window panel of the door.

[0035] Preferably, the at least one wire has a length measured from the pull-off element on the appliance side to the pull-off element on the door side, such that the movement of the user of the cooking appliance pulling the at least one wire out of the receiving chamber is limited to a predetermined amount. Furthermore, it is preferable that the length of the at least one wire between the two pull-off elements is arranged to allow movement of the at least one wire relative to the wire protection element when the door is opened and closed.

[0036] Nevertheless, the length is preferably not so great that the user of the cooking appliance can pull the cord out of the receiving chamber to a greater extent. This is advantageous in terms of avoiding undesirable loads on the at least one cord, and especially in terms of avoiding the at least one cord getting caught when the door is closed.

[0037] In particular, it can be specified that the predetermined value is between approximately 10 mm and 20 mm, and for example, approximately 15 mm. In this way, it is particularly reliable to avoid the formation of undesirable loops or bends in the at least one conductor in an area accessible when the door is open. This is also advantageous in terms of the long-term functional reliability of the at least one conductor.

[0038] Preferably, the at least one wire passes through a through-hole at the tension-relieving element on the door side, the through-hole being constructed in the first window panel. This allows power to be supplied to at least one component of the cooking appliance in an advantageous manner via the at least one wire in the area of ​​the door adjacent to the first window panel on the front side.

[0039] Preferably, a modular assembly is arranged on the front side of the first window panel. Here, the modular assembly includes another window panel spaced apart from the first window panel. This other window panel, when the door is closed, is further away from the cooking compartment than the first window panel. In this way, power can be supplied to the components of the modular assembly via the wires.

[0040] Preferably, the handle element for opening the door is formed using the modular assembly. The handle element provided by such a large-area modular assembly can be advantageously used to cause movement of the door about a pivot axis when the door is opened, by the user of the cooking appliance applying a pulling force to the modular assembly forming the handle element.

[0041] The modular assembly, particularly the frame in which it is arranged between the first and second window panels, provides a handle groove (Griffmulde) into which the user can insert to open the door. This is advantageous for easy operation of the door when opening.

[0042] Preferably, electrical energy can be supplied to at least one component of the modular assembly, arranged in the gap between the first and second window panels, via the at least one conductor. For example, electrical energy can be supplied to at least one light source of the modular assembly so that the light source can emit light during operation. Then, lighting, especially ambient lighting, can be easily and particularly easily achieved by means of the modular assembly.

[0043] As a supplementary or alternative solution, the at least one wire may include an electrical conductor configured to ground at least one component of the module assembly. This is advantageous in terms of electrical safety during the operation of the module assembly.

[0044] As a supplementary or alternative solution, data can be transmitted via the at least one wire to at least one component of the module assembly arranged in the gap between the first and second window panels. Correspondingly, as a supplementary or alternative solution, the at least one wire can be configured as a data line and / or include at least one data line. Therefore, control commands, such as control commands for manipulating a light source of the module assembly, for example, a light-emitting diode, can be transmitted to the corresponding component of the module assembly.

[0045] Regarding the functionality of the at least one wire, the improved wire guide is advantageous because it easily and reliably prevents damage to the at least one wire.

[0046] Preferably, the tension-relieving element on the door side has multiple centering arms that abut against a wall that circumferentially limits the through-hole and is provided by a first window plate. Such centering arms facilitate the placement of the tension-relieving element on the first window plate in the region of the through-hole. Additionally, the centering arms protect at least one wire, as they help prevent at least one wire from contacting the wall that limits the through-hole.

[0047] Preferably, at least one of the centering arms has an extruded rib. In particular, at least one extruded rib can be constructed on each centering arm. Such a rib is one that is particularly plastically deformed when the tension-relieving element is placed on the door (where the centering arm is inserted into the through hole) and thus serves to hold the tension-relieving element particularly reliably in the through hole formed in the first window panel.

[0048] As a supplementary or alternative solution, it can be specified that the door-side tension-relieving element has at least one locking arm, the locking arm including a locking section abutting against the front side of the first window panel. With such a locking arm arrangement, reliable and easy installation of the door-side tension-relieving element in the area of ​​the through-hole, wherein the through-hole is constructed in the first window panel, is possible.

[0049] Furthermore, the locking section of the at least one locking arm, which engages with the first window panel from the rear and abuts against the front side of the first window panel, is used to securely and very firmly fix the position of the door-side tension-relieving element to the first window panel. Moreover, the engagement of the at least one locking arm, when engaging the first window panel from the rear, can be advantageously felt and / or heard by the installer performing the installation work on the door-side tension-relieving element on the first window panel.

[0050] This is particularly true of at least one locking arm of the tension relief element on the door side being elastically configured and thus applicable when engaging the first window panel from the rear after passing through the through hole, wherein the locking section of the at least one locking arm contacts the front side of the first window panel.

[0051] Preferably, the tension-relieving element on the door side includes a channel section extending along the direction of the wire protection element, in which the at least one wire is arranged. In this way, the at least one wire is protected in the area of ​​the first window panel of the door through the channel section. Furthermore, the at least one wire is advantageously pre-defined in the direction along which it should extend toward the wire protection element. This is advantageous in terms of the improved wire guide.

[0052] Preferably, multiple ribs are arranged on the opposing sidewalls of the passage section to clamp at least one conductor. This makes it particularly easy to prevent movement of the at least one conductor when the door is opened or closed in the area of ​​the tension-relieving element.

[0053] Preferably, the sidewall of the channel section abuts against the inner surface of the first window panel with its narrow side. This achieves a very simple construction of the channel section extending along the direction of the wire protection element, allowing the at least one wire to be easily and conveniently inserted into the channel section during installation.

[0054] Preferably, the tension-relieving element on the door side has a support plate that abuts against the inner surface of the first window panel. This is advantageous in terms of positioning the tension-relieving element on the door side within the first window panel of the door. The support plate can be integrally formed with the base of the tension-relieving element. In other words, this is particularly convenient.

[0055] Preferably, the door-side tension-relieving element can be secured to the first window panel by means of a fastening element passing through a fastening hole constructed in the support plate. This is because a particularly reliable fixation of the door-side tension-relieving element to the first window panel is achieved by inserting the fastening element, for example, as a screw, into the fastening hole. In this case, the door-side tension-relieving element is fixed to the first window panel by means of the fastening element. However, it is also possible to specify that although the support plate has fastening holes, these holes remain almost unused. Nevertheless, it is particularly possible to pass the fastening element through the fastening hole and tighten it to secure the door-side tension-relieving element to the first window panel.

[0056] Preferably, the at least one wire has a protective sleeve. This, for example, helps to minimize damage to the at least one wire when it moves relative to the hinge base and the wire protection element that maintains its position during opening and closing of the door, together with the protective sleeve. In particular, the protective sleeve can include a braided material. This provides particularly reliable protection for the at least one wire.

[0057] In particular, the protective sleeve comprising the braided material enables the composite structure, including the at least one conductor and the protective sleeve, to be advantageously constructed in a relatively bend-resistant manner, such as in the form of a cable. This is also advantageous in that it minimizes damage to the at least one conductor due to bending loads.

[0058] As a supplementary or alternative solution, the at least one wire can have a sheath made of a lubricating material. This allows for very low-friction movement of the at least one sheathed wire along the receiving chamber during opening and closing of the door.

[0059] Preferably, the lubricating material is durable against temperatures encountered during the operation of the cooking appliance, for example, by means that the sheath is formed of a tetrafluoroethylene-hexafluoroethylene copolymer, also known as a fluorinated ionomer (FEP). A sheath made of such a material not only provides exceptionally high slip capability along the wire protection element within the receiving chamber, but also ensures good durability against extreme temperatures that may occur during the operation of the cooking appliance. This is advantageous.

[0063] In the accompanying drawings, identical or functionally identical elements are given the same reference numerals. Detailed Implementation

[0064] exist Figure 1 The image shows a cooking appliance 1 in a schematic perspective view. The cooking appliance 1 includes a housing 2 with a muffle oven 3. The walls of the muffle oven 3 define the cooking chamber 4 of the cooking appliance 1. Furthermore, the cooking appliance 1 includes a door 5, which is arranged on the housing 2 in a movable manner, specifically in a manner capable of pivoting about a pivot axis A. By means of the door 5, the cooking chamber 4 can be closed from the front when the door 5 is moved to the closed position. Figure 1 In the image, the door 5 is shown in a partially open position.

[0065] In addition, Figure 1 The coordinate system shows the lateral direction (x or width), the depth direction (y), and the height direction (z) of the cooking appliance 1. If the door 5 is closed, it therefore extends substantially along a plane opened by the height direction (z) and the lateral direction (x or width). This orientation of the door 5 is... Figure 2 As shown in the diagram, door 5 can be seen in the front view.

[0066] Especially from Figure 2 and Figure 3 As can be seen from the overview, the door 5 has a first window panel, which is configured here as the front window panel 6 of the door 5. Furthermore, the door 5 has a modular assembly 7 arranged on the front side 8 of the front window panel 6. The modular assembly 7 includes another window panel 9 or a front window panel 9 arranged spaced apart from the front window panel 6 along the depth direction y.

[0067] exist Figure 3 In the image, the door 5 is shown in its installation position, that is, when the door 5 is placed on the housing 2 of the cooking appliance 1 (see also...). Figure 1 Furthermore, the gate 5 in Figure 3 The door 5 is shown in its closed position. In this closed position, the front window panel 6 is closer to the cooking chamber 4 of the cooking appliance 1 than the other window panel 9. Therefore, a gap is created between the front window panel 6 and the other window panel 9.

[0068] In this gap area, a handle slot 11 is provided by the frame 10 of the modular assembly 7, into which a user can reach to open the door 5. Figure 3 The closed position shown is moved to the open position. In other words, the user can apply a pulling force to the large-area handle element provided by the modular assembly 7 to open the door 5, and in particular, cause the door 5 to deflect or pivot upward about the pivot axis A. For this purpose, in the design of the door 5 shown in this exemplary embodiment, the modular assembly 7, or the handle element formed by the modular assembly 7, has a handle groove 11. Thus, as for example by Figure 2 As can be seen, in order to open door 5, a handle with a lever or similar device can be omitted.

[0069] The door 5 comprises a plurality of door profiles in a manner known per se, wherein among these door profiles... Figure 3The diagram exemplarily shows a lateral door profile 12 on which the front window panel 6 is arranged. Furthermore, in a manner known per se, the front window panel 6, viewed along the depth direction y of the cooking appliance 1, can be the window panel in front of a window panel assembly of the door 5, wherein such a window panel assembly can include multiple window panels that follow each other sequentially along the depth direction y.

[0070] from Figure 2 and Figure 3 In particular, it can be seen from the overview that the front window panel 6 here has a larger size along the height direction z and along the lateral direction x than the other front window panel 9 belonging to the module package 7.

[0071] exist Figure 3 In the diagram, the handle groove 11 provided by the frame 10 of the modular assembly 7 is only shown in the area near the hinge below the door 5. However, in practice, this handle groove 11 surrounds the frame 10 on the circumferential side, which here comprises four frame elements. In the exemplary design shown for the modular assembly 7, these frame elements are constructed as four profile members 13, 14 (see...). Figure 2 ).

[0072] Here, the frame 10 includes two profile members 13 that extend in the lateral direction x in the mounting position of the door 5 when the door 5 is closed, and these two profile members are designed to... Figure 2 The upper and middle profile 13 and in Figure 2 The frame 10 is constructed in the form of a profile member 13 at the lower center. Furthermore, the frame 10 includes two profile members 14 that extend along the height direction z when the door 5 is closed. These two profile members are configured to... Figure 2 Profile 14 on the left side and in Figure 2 It is composed of profile 14 on the right side.

[0073] Furthermore, the module assembly 7 here has a light source, not shown in detail, such as in the form of a light-emitting diode, which, during operation, i.e., when powered by electricity, couples light into the corresponding light conductor 15 of the module assembly 7, wherein... Figure 3 Only two of the light conductors 15 are visible. During operation of the light source, light coupled out from the light conductors 15 illuminates the visible surface 16 of the frame element 17, which is constructed according to the pattern of a picture frame (Passepartout), and is oriented at an angle. Figure 2 This can be seen in the front view.

[0074] These visible surfaces 16, in this embodiment, are oriented obliquely from the other window panel 9 toward the front window panel 6 (see...). Figure 3The visible surface 16 is visible to an observer looking towards the front window panel 6 through the front window panel 9. The visible surface 16 can be loaded with light emitted or coupled out from the light conductors 15, wherein a corresponding light conductor in one of the four light conductors 15 runs along profiles 13, 14 (see...). Figure 2 Extend from the corresponding profile component in ).

[0075] Specifically, for the purpose of supplying electrical energy to the light source, the cooking appliance 1 has at least one wire 18, the wire's path, starting from the housing 2 of the cooking appliance 1 or with the housing 2 as the starting point, and extending into the door 5, is as follows: Figure 3 It is illustrated schematically. Figure 3 For simplicity, only conductor 18 is shown, wherein at least one conductor 18 laid in door 5 can be configured to conduct current and / or be configured as a data line and / or be configured as a safety lead causing grounding, etc. In particular, the description in Figure 3 The conductor 18 shown in the example can be configured according to the pattern of cable strands, which include a plurality of conductors and / or data lines formed of corresponding conductive materials.

[0076] Thus, through the at least one conductor 18, current and / or data can preferably be persistently and reliably conducted to the door 5, which is here configured as a flip door, of the cooking appliance 1, which is particularly configured as an oven, in order to provide current and / or data to the corresponding load or component, particularly belonging to the modular kit 7.

[0077] Depend on Figure 3 It can be seen that the wire 18 extends into the gap formed between the front window panel 6 and the other window panel 9, or the front window panel 9. This gap is achieved by means of... Figure 3 The sealing element 19, partially shown in the middle, seals against the surrounding environment.

[0078] In addition, Figure 3 The line 20 shows the position of the door 5. Figure 3 The approximate location of the inner window panel is not shown for simplicity. Therefore, with door 5 closed, this inner window panel rests against the flange member, which... Figure 3 Partially shown, and the flange member herein constructed as a furnace flange 22 surrounding the loading port 21 of the cooking chamber 4. Figure 4 In the diagram, the furnace flange 22 surrounding the charging port 21 is shown in a front view. Therefore, when the door 5 is closed, the inner window plate of the door 5 abuts against this furnace flange 22, or rather, against the seal located in the area of ​​the furnace flange 22.

[0079] In order for the door 5 to revolve around the pivot axis A (see Figure 1 The cooking appliance 1 has two hinges 23, wherein one of the hinges 23, which are opposite each other along the lateral direction x of the cooking appliance 1, is, for example, in... Figure 4 As shown in the image. For example, from... Figure 4 and Figure 5 In a glance, but also from Figure 6 As can be seen in this context, the corresponding hinge 23 includes a hinge base 24, which is square and slightly elongated, extending along the depth direction y of the cooking appliance 1. Furthermore, the hinge 23 includes a hinge brace 25 that extends along the height direction z of the cooking appliance 1 when the door 5 is closed (see [link to previous section]). Figure 4 Furthermore, the door 5 is fixed to the hinge brace.

[0080] The hinge base 24 of the corresponding hinge 23 is fixed to the housing member of the housing 2, wherein the housing member is configured as the edge 26 of the cooking appliance 1. The edge 26, constructed according to the pattern of the side wall element or lateral support element of the cooking appliance 1, is... Figure 4 It is shown in the front view and in Figure 3 The image is partially shown in a side view. The furnace flange 22 is also fixed to the edge 26, in addition to the hinge base 24.

[0081] Especially from Figure 5 and Figure 6 As can be seen at a glance, a wire protection element, which serves as a cable channel 28 or cable trough, is arranged on the outer surface 27 of the hinge base 24. This wire protection element laterally defines a receiving chamber 29, in which the at least one wire 18 is received. The cable channel 28... Figure 7 The perspective view shown in the figure shows the possible orientation of the receiving chamber 29 along the depth direction y of the cooking appliance 1.

[0082] Specifically, the cable channel 28 includes a wall 30 having a U-shaped profile in cross-section, which defines a receiving chamber 29 along the transverse direction x of the cooking appliance 1. The cable, or wire 18, is protectively arranged inside the receiving chamber 29. Figure 3 In this context, more precisely, the routing of the conductor 18 through the cable channel 28 is shown, although the conductor 18, which is concealed by the wall 30, is... Figure 3 It is impossible to see them continuously in the middle.

[0083] Especially from Figure 3 and Figure 5As can be seen from the overview, the wall 30 defines the receiving chamber 29 for the wire 18 towards the furnace flange 22. The cable channel 28, which serves as an insertion aid when installing the wire 18, thereby prevents the wire 18, or cable, from coming into contact with the furnace flange 22, which is sometimes hot.

[0084] The receiving chamber 29, which is limited on one side by the wall 30 of the cable channel 28, also serves as a guide rail when operating the cooking appliance, that is, when opening and closing the door 5. This is because the movement of the receiving chamber 29, which extends along the depth direction y of the cooking appliance 1 and is accompanied by the opening and closing of the cable 18 and the door 5, can be achieved by the cable channel 28, which serves as a guide or rail.

[0085] The movement of the cable or conductor 18 relative to the hinge body 24 and the conductor protection element in the form of a cable channel 28 mounted on the hinge base 24... Figure 3 The double arrow 31 is used to indicate this. During the movement of the conductor 18 caused by the opening and closing of the door 5, the hinge base 24 and the conductor protection element, which takes the form of the cable channel 28 shown here exemplary, remain in a fixed position.

[0086] Especially from Figure 3 Together Figure 5 As can be seen, the end region 32 of the wall 30 near the door protrudes beyond the oven flange 22 along the depth direction y of the cooking appliance 1 toward the door 5. In this way, contact between the at least one wire 18 and the oven flange 22 is reliably avoided.

[0087] In addition, from Figure 3 As can be seen, a through hole 33 is constructed in the front window panel 6, through which the cable or wire 18 reaches the gap formed between the front side 8 of the front window panel 6 and another window panel 9 or the front window panel 9.

[0088] In the region of this through-hole 33, the wire 18 is held by the tension relief element 34, which is transparently visible through the hole. Figure 10 As shown in the diagram, the tension unloading element can be used in... Figure 3 This is seen in the state where it is installed on the front window panel 6. The tension-relieving element 34 on this door side includes a channel section 35 extending toward the hinge 23, or rather toward the cable channel 28, and thus along the height direction z of the cooking appliance 1 when the door 5 is closed. This channel section 35 is used for the orientation of the guide wire 18 toward the rotation axis A of the door 5, which is here configured as a hinged door or the cooking appliance door. The guide wire 18 is guided from the rotation axis A via the arc-shaped section toward the end region 32 of the wall 30, and thus toward the end region of the receiving chamber 29 near the door, or rather, near the door entrance.

[0089] The wire protection element, which is fastened here to the hinge 23 and takes the form of a cable channel 28, is advantageously installed in place of a cable chain or cable hose, etc.

[0090] The conductor 18 advantageously has, on the one hand, a protective sheath, not shown in detail herein, such as being constructed as a braid or including a braid. Due to this braided sheath, the conductor 18 is relatively bend-resistant. Furthermore, the conductor 18 preferably has a sheath 36 formed of a lubricating material, preferably made of a material durable against the temperatures encountered during operation of the cooking appliance 1. Due to this sheath 36, the relatively bend-resistant cable, or the relatively bend-resistant conductor 18, remains well slidable, allowing the conductor 18 to move along the receiving chamber 29 with considerable freedom of movement. The corresponding movement is... Figure 1 The double arrow 31 is used to indicate this.

[0091] In the region behind the cable channel 28, the conductor 18 is guided to the tension relief element 38 on the appliance side in the form of a U-shaped arc 37. Figure 3 The design is shown only schematically and not in its actual structural form. Here, the tension relief element 38 on the side of the device is fastened to the edge 26.

[0092] In the cable channel 28 Figure 3 In the design shown, the receiving chamber 29 has a wire outlet 39 in the end region away from the door, which is arranged or constructed on the upper side of the cable channel 28 (see [reference]). Figure 6 Correspondingly, in this design of the cable channel 28, the arc 37 begins in the area of ​​the receiving chamber 29.

[0093] In contrast, in the cable channel 28 Figure 9 In the variant shown, the wire outlet 39 is constructed at the end of the cable channel 28 away from the door. Correspondingly, in this design of the cable channel 28, the wire 18 is laid over a longer length along a section of the receiving chamber 29 that extends along the depth direction y of the cooking appliance 1.

[0094] In both variations, it is preferably specified that the length of the guide wire 18, and especially the arc 37, measured from the tension relief element 38 on the appliance side to the tension relief element 34 on the door side, is sufficient to allow relative movement of the guide wire 18, which is caused by the opening of the door 5 and by the closing of the door 5 in the form of deflection of the door 5 about the pivot axis A. Furthermore, it is preferable to measure this length in such a way that the pulling of the guide wire 18 from the receiving chamber 29 by the user of the cooking appliance 1 is limited to a predetermined amount.

[0095] Specifically, it can be stipulated that the user or customer cannot pull the wire 18 out of the receiving chamber 29 by more than, for example, 15 mm. This is especially important for the pivot axis A of the door 5 (see...). Figure 1 In the area that is accessible when the door 5 is open, loops or bends will not be unintentionally formed in the wire 18.

[0096] In addition, especially from Figure 3 Together Figure 5 As can be seen, the guide wire 18, positioned close to the hinge 23, ensures good accessibility to the discharge channel 40 formed by the furnace flange 22 for cleaning. Therefore, the guide wire 18 does not interfere with the cleaning or wiping process.

[0097] Especially from Figure 6 and Figure 7 As can be seen from the overview, the receiving chamber 29, which is limited by the wall 30 of the cable channel 28, is preferably limited by the outer surface 27 of the hinge base 24 on the side opposite the wall 30 in the lateral direction x of the cooking appliance 1. By means of Figure 7 and Figure 8 This can explain the possible connection or fixation of the cable channel 28 on the outer surface 27 of the hinge base 24.

[0098] Therefore, the cable channel 28 has a locking member 41 preferably integrally formed with the base of the cable channel 28, which functions as a bayonet-type locking member. Correspondingly, two locking pins 42 extend vertically from the rod portion 42 of the locking member 41, which cooperate with corresponding (not shown in detail here) receiving portions when the cable channel 28 is placed on the hinge base 24 to achieve bayonet-type locking.

[0099] Here, the locking member 41, which bears the main force in the installed state of the cable channel 28, is arranged in the end region of the cable channel 28 near the door. In the opposite end region of the cable channel 28, a locking element configured according to the pattern of a hook 44 is arranged as a fastening element, protruding from the wall 45 of the cable channel 28 extending along the height direction z of the cooking appliance 1 toward the hinge base 24. After the locking member 41, which has a bayonet-type locking function, is locked, the hook 44 engages with a corresponding receiving opening, such as a screw hole, when the cable channel 28 is installed onto the hinge base 24.

[0100] Furthermore, the cable channel 28 has a stop element 46 disposed on its lower side, which can... Figure 8 This is more clearly seen in the diagram. The stop element 46 serves as an end stop, which provides support when the cable channel 28 is mounted onto the hinge base 24. Here, the stop element 46 can be embedded into a corresponding receiving portion formed on the hinge base 24. Furthermore, the stop element 46, as shown here... Figure 8 The shown can have a locking lug 47 or a similar locking element, which engages from the rear with the wall 59 of the hinge base 24 (see [link]). Figure 8 ).

[0101] exist Figure 10 The perspective view shows a first variant of the door-side tension relief element 34. Therefore, the tension relief element 34 has a flange 48 that abuts against the inner surface 49 of the front window panel 6 when the tension relief element 34 is mounted to the front window panel 6 (see...). Figure 3 Furthermore, the narrow sides of the opposing sidewalls 50 of the passage section 35 abut against the inner side surface 49 of the front window panel 6. Additionally, from... Figure 10 As can be seen, multiple ribs 51 extend from these sidewalls 50 to clamp the wire 18, which is sandwiched between the ribs.

[0102] Furthermore, the tension-relieving element 34 on the door side passes through the through hole 33 in the front window panel 6 (see...). Figure 3 The region contains multiple centering arms 52, with three centering arms 52 evenly spaced from each other along the circumferential direction of the through hole 33. Each centering arm 52 may have corresponding transverse ribs 53 on its outer surface, which, in the installed state of the tension relief element 34, abut against the wall of the circumferentially limiting through hole 33 and provided by the front window panel 6. These centering arms 52, and in the illustrated example, the two locking arms 54, serve here as lateral protection for the passage of the guide wire 18 through the front window panel 6, which is formed here as glass.

[0103] The preferred elastically configured locking arm 54 has a corresponding locking section 55 configured according to the pattern of the locking lug, wherein when the tension relief element 34 on the door side is installed on the front glass 6, the locking section 55 of the locking arm 54 abuts against the front side 8 of the front window panel 6.

[0104] exist Figure 13 A second variation of the door-side tension relief element 34 is shown, wherein a support plate 56 is integrally formed with the base of the tension relief element 34, and the support plate has a fastening hole 57. A screw (not shown) can pass through the fastening hole 57 of this support plate 56 or the threaded connecting plate to reliably secure the door-side tension relief element 34 to the front window panel 6.

[0105] Therefore, a portion of the tension relief element 34, including the locking arm 54 and the centering arm 52, can be first inserted into the through hole 33. Subsequently, to secure the tension relief element 34 on the door side in a particularly load-bearing manner, the tension relief element 34 can be screwed together with the front window panel 6 in the area of ​​the support plate 56.

[0106] In the tension unloading element 34 Figure 13 The variant shown includes two support walls 58 that extend from a support plate 56 abutting against the inner side 49 of the front window panel 6 to the side wall 50 of the passage section 35. These support walls 58 improve the stability of the support plate 56.
