An operating condition of the household cooking appliance 1 may be displayed with the aid of the display field 15. For example, with the aid of the display field 15 a temperature that has been set using the operating knobs 12, 13 may be displayed.

(13) The door 3 has a plurality of panes 16, of which only one, namely a front pane, is shown in FIG. 1. Further, the door 3 includes a first door profile 17 and a second door profile 18 that are positioned at a spacing from one another and parallel to one another. The door profiles 17, 18 may be fastened on the rear side of the pane 16, that is to say facing the cooking chamber 2, in particular being bonded to the pane 16 by adhesion. In a closed condition of the door 3, the door profiles 17, 18 run in a Z direction z of the household cooking appliance 1. Further, FIG. 1 also shows an X direction x and a Y direction y of the household cooking appliance 1.

(14) FIG. 2 shows a schematic partial sectional view of the door 3. The door 3 includes a plurality of panes 16 and 19 to 21. The panes 16 and 19 to 21 may be made for example from a glass material, and are at least partly transparent. The pane 19 may also be designated the first pane or inner pane, the pane 20 may also be designated the second pane or the first intermediate pane, the pane 21 may also be designated the third pane or second inner pane, and the pane 16 may also be designated the fourth pane or front pane. The door profiles 17, 18 are preferably firmly connected to an inner face 22 of the pane 16, for example being bonded by adhesion.

(15) Each door profile 17, 18 has a receiving portion 23 for receiving the first pane 19. The receiving portion 23 has for example a hook shape and can reach around an edge 24, in particular an upper edge or a lower edge, of the first pane 19, at least in certain regions. Each door profile 17, 18 further has a receiving portion 25 that is intended to position the second pane 20 and the third pane 21 in the door 3. For this purpose, an edge 26, in particular an upper edge or a lower edge, of the second pane 20 and an edge 27, in particular an upper edge or a lower edge, of the third pane 21 may abut against the receiving portion 25.

(16) With the aid of the door profiles 17, 18, the panes 16 and 19 to 21 may be arranged parallel to one another and at a spacing from one another. Here, each pane 16 and 19 to 21 represents one level. In particular, the second pane 20 is arranged at a spacing from the first pane 19, the third pane 21 is arranged at a spacing from the second pane 20, and the fourth pane 16 is arranged at a spacing from the third pane 21. Here, the spacings between the panes 16 and 19 to 21 may be different or alike. Air can circulate between the panes 16 and 19 to 21. A first gap S1 is provided between the first pane 19 and the second pane 20, a second gap S2 is provided between the second pane 20 and the third pane 21, and a third gap S3 is provided between the third pane 21 and the fourth pane 16. The door profiles 17, 18 are arranged between the first pane 19 and the fourth pane 16. However, and also at least in certain regions, the door profiles 17, 18 are arranged between the first pane 19 and the second pane 20 and between the first pane 19 and the third pane 21.

(17) The door 3 further includes a sealing device 28. As shown in FIG. 2, the sealing device 28 may be arranged in the first gap S1, between the first pane 19 and the second pane 20. As an alternative, the sealing device 28 may also be arranged between the second pane 20 and the third pane 21 or between the third pane 21 and the fourth pane 16. The sealing device 28 is fastened to both the first door profile 17 and the second door profile 18. In particular, the sealing device 28 is connected form-fittingly to the first door profile 17 and the second door profile 18. A form-fitting connection is produced when at least two connected parts, in this case the door profiles 17, 18 and the sealing device 28, engage in or behind one another. In particular, the sealing device 28 is suspended in the first door profile 17 and the second door profile 18. Here, the sealing device 28 may be suspended in the door profiles 17, 18 in a pretensioned manner.

(18) The sealing device 28 that is shown in FIG. 3 in a schematic perspective view includes a resiliently deformable sealing element 29 that is made for example from a silicone material. The sealing element 29 extends perpendicular to the door profiles 17, 18 and is positioned between them. The sealing element 29 may have any desired cross sectional geometry. For example, the sealing element 29 may take a hollow form, at least in certain regions. The sealing element 29 includes a plurality of sealing lips 30 to 33. Here, the sealing lips 30, 31 are intended to seal the sealing element 29 in relation to the first pane 19, and the sealing lips 32, 33 are intended to seal the sealing element 29 in relation to the second pane 20.

(19) In addition to the sealing element 29, the sealing device 28 includes a first suspension hook 34 for suspending the sealing device 28 in the first door profile 17, and a second suspension hook 35 for suspending the sealing device 28 in the second door profile 18. Preferably, the suspension hooks 34, 35 are made from a steel material. The suspension hooks 34, 35 may be connected form-fittingly or in a substance-to-substance bond to the sealing element 29. In the case of substance-to-substance bonds, the connected parts are held together by atomic or molecular forces. Substance-to-substance bonds are non-detachable connections, which can only be severed by destroying the means of connection and/or the connected parts. For example, the suspension hooks 34, 35 are bonded to the sealing element 29 by adhesion. Each suspension hook 34, 35 includes a connection portion 36 that is firmly connected to the sealing element 29, a hooking portion 37 that is arranged parallel to the connection portion 36, and an intermediate portion 38 that connects the connection portion 36 to the hooking portion 37.

(20) As shown in FIG. 4, the door profiles 17, 18 each have a receiving portion 39, in particular an aperture or bored hole. Suspended in the receiving portions 39 is the sealing device 28, wherein the hooking portion 37 of the suspension hooks 34, 35 is guided through the receiving portion 39. The receiving portion 39 takes for example the form of an aperture that passes through a side wall 40 of the respective door profile 17, 18. The receiving portion 39 may have any desired geometry. For example, the receiving portion 39 may also be a circular bored hole. Associated with each receiving portion 39 is a groove portion 41, which is arranged at a spacing therefrom. The connection portion 36 of the respective suspension hook 34, 35 comes to lie in the groove portion 41 such that the connection portion 36 does not lie on the upper side of the door profile 17, 18, as a result of which a mechanical load on the first pane 19 is avoided, since this can lie flat on a surface 42 of the respective door profile 17, 18.

(21) As shown in FIGS. 5 to 7, the suspension hooks 34, 35 are fixed on the respective door profile 17, 18 with the aid of the receiving portion 39 and the groove portion 41. This defines the position of the sealing device 28, and it cannot slip. Because the sealing device 28 is suspended in the door profiles 17, 18, there is no need to fasten the sealing device 28 to one of the panes 19, 20, but rather, independently of the panes 19, 20, it can be suspended from the door profiles 17, 18, which are connected to the fourth pane 16. As a result, the sealing device 28 may span a greater width of the first gap S1 between the panes 19, 20 than if it is fastened to only one of the panes 19, 20. Mounting of the sealing device 28 is unambiguously defined by the receiving portions 39 and the groove portions 41 in the door profiles 17, 18. This means that the sealing device 28 cannot be positioned incorrectly. This allows mounting errors to be avoided. The sealing element 29 may have any desired cross sectional geometry and be of any desired material. For example, the sealing element 29 may also be made from a spring steel and be in one piece with the suspension hooks 34, 35. The door profiles 17, 18 may be made for example from metal or plastics. The suspension hooks 34, 35 may also be made from a plastics material or a silicone material. The sealing device 28 is preferably provided in a lower region or on a lower edge 43 of the door 3. The lower edge 43 is positioned remote from the upper edge 4. The sealing device 28 may also be provided on the upper edge 4.

(22) In the case of a door 3 as described above, sealing of the gaps S1, S2 and/or S3 between the panes 16 and 19 to 21 has a positive effect on energy consumption and thus on the cooking results. In particular, each sealed gap can have a positive effect on energy consumption. Air circulation between certain panes 16 and 19 to 21, for example between the panes 19, 20, is avoided and the door 3 can be ventilated between other panes 16 and 19 to 21, for example between the panes 21, 16. The advantages of the household cooking appliance 1 can be seen in the fact that the sealing device 28 is not mounted directly on one of the panes 16 and 19 to 21 but can be suspended directly in the door profiles 17, 18. This makes it possible to avoid the risk that the suspension hooks 34, 35 may actuate one of the panes 16 and 19 to 21.

(23) The suspension hooks 34, 35 are securely installed in the receiving portions 39 of the door profiles 17, 18, and moreover do not present any risk of injury to customers when dismantling and cleaning the door 3. Providing the receiving portions 39 and the groove portions 41 in the door profiles 17, 18 guarantees the position of the sealing device 28 in a reliable process. Incorrect mounting, for example too high up or too low down on one of the panes 16 and 19 to 21, can be avoided both during manufacture and also by customers when dismantling and cleaning the door 3, and proper functioning can thus also be ensured. The fact of mounting the sealing device 28 on the door profiles 17, 18 moreover makes the sealing device 28 independent of the geometry and size of the panes 16 and 19 to 21, so it can be used universally. Because the suspension hooks 34, 35 come to lie in the groove portions 41 in the door profiles 17, 18, there is no need to provide additional structural space for the suspension hooks 34, 35 between the first pane 19 and the second pane 20. Because of this, the first gap S1 between the panes 19, 20 is made larger, as a result of which improved air circulation is possible. As a result, improved energy efficiency can be achieved, and a temperature of the fourth pane 16 can be reduced because of the insulating effect of the first gap S1.

(24) Although the present invention has been described by way of exemplary embodiments, it may be modified in a wide variety of ways.
