[0050] Elements which are the same or functionally the same have been provided with the same reference characters unless specified otherwise.

[0051] FIG. 1 shows a schematic perspective view of an embodiment of a household cooking appliance 1. The household cooking appliance 1 can be a stove, an oven, a microwave combination oven, a double oven, or the like. The household cooking appliance 1 has a cooking chamber 2 which can be closed by means of a door 3. The cooking chamber 2 can also be denoted as a muffle or oven muffle. The cooking chamber 2 can be arranged in the interior of a housing of the household cooking appliance 1. The door 3 is shown in FIG. 1 in a closed position. The door 3 can be closed or opened by pivoting about a pivot axis provided at a lower end of the door 3 or a lower edge 4 of the door 3. Alternatively, the door 3 can be attached to the cooking chamber 2 at the side. Moreover, the door 3 can be arranged on an oven carriage which can be pulled out of the cooking chamber 2. However, it is possible to select any given type of movement of the door 3 when the door 3 is opened. In other words, in principle the door 3 can perform any given movement when opened.

[0052] A handle 6 can be provided on an upper portion or on an upper edge 5 of the door 3. The cooking chamber 2 has a bottom 7, a ceiling 8 arranged opposite the bottom 7, a rear wall 9 arranged opposite the closed door 3 and two side walls 10, 11 arranged opposite one another. The cooking chamber 2 is preferably cuboidal or cube-shaped. The cooking chamber 2 can be produced from a metal material, in particular from a steel sheet.

[0053] The household cooking appliance 1 also comprises control knobs 13, 14 provided on a switch panel or control panel 12. The control knobs 13, 14 can be, for example, rotatable. A control facility 15, only shown schematically, can be provided on the rear face on the control panel 12 for controlling the household cooking appliance 1. The control facility 15 can be a regulating facility and/or control facility. A display 16 can also be provided on the control panel 12. An operating state of the household cooking appliance 1 can be displayed by means of the display 16. For example, a temperature set by means of a control knob 13, 14 can be displayed by means of the display 16.

[0054] The household cooking appliance 1 can be capable of pyrolysis. In other words, the cooking chamber 2 can be burnt out by means of a correspondingly high temperature. Dirt adhering to the cooking chamber 2 and to the door 3 on the inner face is carbonized thereby, so that this dirt either drops off automatically or can be easily removed. However, this pyrolysis function is not absolutely necessary. The door 3 is a ventilated door. In other words, an air flow is conducted through the door 3.

[0055] A coordinate system having a width direction or x-direction x, a height direction or y-direction y, and a depth direction or z-direction z is assigned to the household cooking appliance 1 or the door 3. The directions x, y, z are oriented perpendicular to one another. The door 3 comprises an outer pane 17 which is located in a plane spanned by the x-direction x and the y-direction y. On the rear face, i.e. facing the cooking chamber 2, a first door support 18 and a second door support 19 are attached to the outer pane 17. The door supports 18, 19 run in the y-direction y when the door 3 is closed. The door supports 18, 19 are preferably adhesively bonded to the outer pane 17 on the rear face. The door supports 18, 19 are produced from a plastic material. Hinges, not shown, can be attached to the door supports 18, 19 so that the door 3 can be pivotably attached to the cooking chamber 2.

[0056] FIG. 2 shows a schematic perspective partial view of an embodiment of a door 3 as mentioned above. FIG. 3 shows the view III according to FIG. 2. Reference is made hereinafter to FIGS. 2 and 3 at the same time.

[0057] As mentioned above, the door 3 comprises the outer pane 17, the door supports 18, 19, of which only the first door support 18 is shown in FIGS. 2 and 3, being adhesively bonded thereto. In addition to the outer pane 17, the door 3 comprises an inner pane 20 facing the cooking chamber 2. A first intermediate pane 21 and a second intermediate pane 22 are provided between the outer pane 17 and the inner pane 20. In principle, there can be any given number of intermediate panes 21, 22. The first intermediate pane 21 is arranged closer to the outer pane 17 than the second intermediate pane 22. Accordingly, the second intermediate pane 22 is arranged closer to the inner pane 20 than the first intermediate pane 21. The inner pane 20 is held by a locking facility 23 which is displaceable along the first door support 18. The locking facility 23 can be denoted as a sliding cap.

[0058] During the operation of the household cooking appliance 1, in particular in pyrolysis mode, air circulates between the outer pane 17 and the first intermediate pane 21 and between the first intermediate pane 21 and the second intermediate pane 22. A stationary air cushion is provided between the second intermediate pane 22 and the inner pane 20. This stationary air cushion serves for thermal insulation. However, this stationary air cushion is not absolutely necessary. Dirt can be deposited on the intermediate panes 21, 22, the inner pane 20 and/or on the outer pane 17. Thus, as explained below in more detail, a user can remove the inner pane 20 and the intermediate panes 21, 22 from the door 3 for cleaning.

[0059] FIG. 4 shows a further schematic perspective partial view of the door 3 according to FIG. 2. FIG. 5 shows the view V according to FIG. 4. Reference is made hereinafter to FIGS. 4 and 5 at the same time.

[0060] For mounting and dismounting the inner pane 20 and the intermediate panes 21, 22, the door 3 comprises a pane positioning facility 24. The pane positioning facility 24 is suitable for positioning and thus for mounting the inner pane 20 and the intermediate panes 21, 22 on the door 3. The door 3 can also be dismounted again by means of the pane positioning facility 24. The pane positioning facility 24 can also be denoted as a mounting and dismounting facility. The pane positioning facility 24 can also be denoted as a pane receiver or pane receiving facility. The pane positioning facility 24 is fixedly connected to the door 3, in particular fixedly to the first door support 18. Preferably, such a pane positioning facility 24 is provided on each door support 18, 19. However, only one pane positioning facility 24 is described in detail hereinafter.

[0061] The pane positioning facility 24 comprises a first actuating arm 25, a second actuating arm 26 and a third actuating arm 27. The actuating arms 25 to 27 are fixedly connected together. The pane positioning facility 24 also comprises a rotating pivot 28 about which the pane positioning facility 24 can be pivotably mounted on the first door support 18. The pane positioning facility 24, however, does not have to be rotatably mounted on the first door profile 18. The pane positioning facility 24 can also be rotatably mounted on any given other component of the door 3 about the rotating pivot 28. The actuating arms 25 to 27 are fixedly connected to the rotating pivot 28. In particular, the actuating arms 25 to 27 and the rotating pivot 28 form an integral component. In the present case, “integral” or “one-piece” means that the pane positioning facility 24 is not made up of a plurality of individual components but the actuating arms 25 to 27 and the rotating pivot 28 form a common component.

[0062] In particular, the actuating arms 25 to 27 and the rotating pivot 28 form a component made of a single material. In the present case “made of a single material” means that the actuating arms 25 to 27 and the rotating pivot 28 are produced from the same material throughout. The third actuating arm 27 can alternatively be produced from a different material, in particular from a silicone rubber or from another flexible component. For example, the pane positioning facility 24 is a plastic injection-molded component. The first actuating arm 25 and the second actuating arm 26 are attached to the rotating pivot 28 such that the actuating arms 25, 26 form a U-shaped or C-shaped geometry in the view according to FIG. 5. The third actuating arm 27, when viewed along the rotating pivot 28, is positioned adjacent to the actuating arms 25, 26.

[0063] The second actuating arm 26 comprises a first damping element 29 facing the first actuating arm 25 and a second damping element 30 facing away from the first actuating arm 25. The damping elements 29, 30 are cuboidal or block-shaped. The second actuating arm 26 is arranged between the damping elements 29, 30. Instead of two damping elements 29, 30, a single continuous damping element can also be provided.

[0064] The damping elements 29, 30 can be produced from a different material from the second actuating arm 26. For example, the damping elements 29, 30 are produced from a thermoplastic elastomer (TPE), in particular from a thermoplastic polyurethane (TPU). To this end, the pane positioning facility 24 can be manufactured, for example, by means of a two-component injection-molding method. A third damping element 31 which faces the second actuating arm 26 and a fourth damping element 32 which faces away from the second actuating arm 26 are assigned to the third actuating arm 27. The damping elements 31, 32 can be produced from a different material from the third actuating arm 27. For example, the damping elements 31, 32 can be produced from a TPE, in particular from a TPU. Instead of two damping elements 31, 32 a single continuous damping element can also be provided. An insertion bevel 33 is provided on the third damping element 31. The damping elements 29 to 32 can also be produced from a silicone rubber, for example from a so-called liquid silicone rubber (LSR), an HTV silicone or an RTV silicone. The damping elements 29 to 32 function as spacers. Thus the damping elements 29 to 32 can also be denoted as spacers or spacer elements.

[0065] The pane positioning facility 24 is assigned a spring element 34 in which the rotating pivot 28 is received at least in some portions. The spring element 34 can be part of the pane positioning facility 24. The spring element 34 can be a helical spring or a leaf spring. In particular, the spring element 34 is a helical spring. The spring element 34 is a torsion spring. In other words, the spring element 34 can generate a torque acting on the rotating pivot 28. The spring element 34 pretensions the pane positioning facility 24 relative to the first door support 18 such that the pane positioning facility 24 remains in an initial position AP shown in FIGS. 4 and 5. In the initial position AP the spring element 34 is approximately relaxed. The spring element 34 has a minimum pretensioning in the initial position AP, however, so that the pane positioning facility 24 remains in the initial position AP. A support portion 35 on which the first intermediate pane 21 can be supported is provided on the first door support 18.

[0066] FIG. 6 shows a further schematic perspective partial view of the door 3. FIG. 7 shows the view VII according to FIG. 6. FIG. 8 shows a further schematic perspective partial view of the door 3. FIG. 9 shows the view IX according to FIG. 8. The functionality of the pane positioning facility 24 is explained hereinafter with reference to FIGS. 2 to 9.

[0067] Initially, the pane positioning facility 24 is in the initial position AP shown in FIGS. 4 and 5. As shown in FIGS. 6 and 7, the first intermediate pane 21 is inserted in an insertion direction E in the direction of the outer pane 17. At the same time, the first intermediate pane 21 bears against the first actuating arm 25, whereby the pane positioning facility 24 is rotated from the initial position AP shown in FIGS. 4 and 5 into an intermediate position ZP shown in FIGS. 6 and 7 and at the same time encompasses the first intermediate pane 21. The spring element 34 is tensioned at the same time. The pane positioning facility 24 is rotated at the same time sufficiently far counterclockwise until the first intermediate pane 21 is supported on the support portion 35.

[0068] As shown in FIGS. 8 and 9, the intermediate pane 22 is then inserted in the insertion direction E in the direction of the outer pane 17. The insertion of the second intermediate pane 22 is facilitated by the insertion bevel 33. When the second intermediate pane 22 is inserted, the second intermediate pane 22 comes to rest on the second damping element 30 of the second actuating arm 26, such that the pane positioning facility 24 moves from the intermediate position ZP into an end position EP, in which the second actuating arm 26 is arranged between the first intermediate pane 21 and the second intermediate pane 22. The second intermediate pane 22 is also encompassed by the pane positioning facility 24 when said second intermediate pane moves from the intermediate position ZP into the end position EP. At the same time, the first damping element 29 bears against the first intermediate pane 21, and the second damping element 30 bears against the second intermediate pane 22. The damping elements 29, 30 can be compressed at the same time. Moreover, the third actuating arm 27 is also pivoted such that the second intermediate pane 22 is arranged between the second actuating arm 26 and the third actuating arm 27.

[0069] As shown in FIGS. 2 and 3, the inner pane 20 is then positioned on the third actuating arm 27, in particular on the fourth damping element 32. At the same time, the third actuating arm 27 can be elastically deformed, such that the third damping element 31 bears against the second intermediate pane 22 and the fourth damping element 32 bears against the inner pane 20. The damping elements 31, 32 can be compressed at the same time. In this case, the third actuating arm 27 is optional. The function of the third actuating arm 27 is for receiving and positioning the damping elements 31, 32 between the second intermediate pane 22 and the inner pane 20. The damping elements 31, 32 are compressed when the inner pane 20 is mounted. After the inner pane 20 is mounted, the locking facility 23 is inserted into the first door support 18 so that the locking facility 23 fixes the inner pane 20 and pushes it against the fourth damping element 32. At the same time, the locking facility 23 partially encompasses the inner pane 20.

[0070] The advantages of the pane positioning facility 24 are explained hereinafter. The pane positioning facility 24 is fixedly mounted in each case on the door 3 or on the respective door support 18, 19. Thus the pane positioning facility 24 is captively connected to the door 3. The return of the pane positioning facility 24 into the initial position AP is ensured by the integration of the spring element 34. The function of the pane positioning facility 24 is independent of a top panel or an upper terminal strip of the door 3. No tool is required for dismounting and mounting the inner pane 20 and the intermediate panes 21, 22.

[0071] The pane positioning facility 24 can be produced from different materials, whereby the damping properties of the damping elements 29 to 32 can be adapted. The insertion bevel 33, which facilitates the mounting of the second intermediate pane 22, is provided on the third damping element 31. The pane positioning facility 24 can be used both when the door 3 is mounted on the household cooking appliance 1 and when the door 3 is dismounted from the household cooking appliance 1. The pane positioning facility 24 can also be produced from metal instead of plastic. The pane positioning facility 24 is captively connected to the respective door support 18, 19. By means of the flexibly deformable damping elements 29 to 32, a large tolerance compensation is possible. Moreover, the door 3 can be dismantled by using just one hand. Further functions, such as for example pane testing, are able to be combined with the pane positioning facility 24.

[0072] While the invention has been described by way of exemplary embodiments, it can be modified in many different ways.
