[0057] Elements which are the same or functionally the same have been provided with the same reference signs in the figures, unless specified otherwise.

[0058] 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 type of movement of the door 3 when the door 3 is opened. In other words, in principle the door 3 can perform any movement when opened.

[0059] A handle 6 can be provided on an upper portion or on an upper edge 5 of the door 3. However, the door 3 can also be without a handle. 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 sheet steel.

[0060] 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 rotatable, for example. 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 the control knobs 13, 14 can be displayed by means of the display 16.

[0061] 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.

[0062] A coordinate system having a width direction or x-direction x, a vertical 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. When the door 3 is closed, the door supports 18, 19 run in the y-direction y. The door supports 18, 19 are preferably adhesively bonded to the outer pane 17 on the rear face. However, the door supports 18, 19 can be connected in any other manner to the outer pane 17. For example, the door supports 18, 19 are mounted in the outer pane 17. The door supports 18, 19 are produced from a plastics 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.

[0063] FIG. 2 shows a schematic plan view of an embodiment of a door 3A for the household cooking appliance 1, when viewed in the direction from the cooking chamber 2 to the door 3A on the rear face. FIG. 3 shows a sectional view of the door 3A along the cutting line III-III of FIG. 2. Reference is made to FIGS. 2 and 3 hereinafter at the same time.

[0064] As mentioned above, the door 3A comprises the outer pane 17, the door supports 18, 19 being adhesively bonded thereto on the rear face. However, the door supports 18, 19 can also be connected in any other manner to the outer pane 17. In addition to the outer pane 17, the door 3A comprises an inner pane (not shown) facing the cooking chamber 2. A first intermediate pane and a second intermediate pane (not shown) can be provided between the outer pane 17 and the inner pane. In principle, there can be any number of intermediate panes. The first intermediate pane is arranged closer to the outer pane 17 than the second intermediate pane. Accordingly, the second intermediate pane is arranged closer to the inner pane than the first intermediate pane.

[0065] 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 and between the first intermediate pane and the second intermediate pane. A stationary air cushion is provided between the second intermediate pane and the inner pane. This serves for thermal insulation. However, this stationary air cushion is not absolutely necessary. Dirt can be deposited on the intermediate panes, the inner pane and/or on the outer pane 17. Thus a user can remove the inner pane and the intermediate panes from the door 3A for cleaning.

[0066] The door supports 18, 19 run in the y-direction y and are positioned spaced apart from one another, when viewed in the x-direction x. The outer pane 17 comprises an inner face 20 which faces the cooking chamber 2 as well as an outer face 21 which faces away from the cooking chamber 2. The door supports 18, 19 are provided on the inner face 20. The door 3A further comprises a shielding facility 22A which is provided on the inner face 20. The shielding facility 22A runs between the first door support 18 and the second door support 19, when viewed in the x-direction x. In other words, the shielding facility 22A runs in the x-direction x.

[0067] The first door support 18 and the second door support 19 are covered or concealed at least in some portions by the shielding facility 22A, when viewed in the direction from the cooking chamber 2 to the outer pane 17. In particular, the door supports 18, 19 are arranged, or at least one of the door supports 18, 19 is arranged, at least in some portions between the outer pane 17 and the shielding facility 22A. Thus the door supports 18, 19 are held on the door 3A even if the connection of the door supports 18, 19 or one of the door supports 18, 19 to the door 3A fails.

[0068] The shielding facility 22A is suitable for shielding the outer pane 17, the door supports 18, 19 and/or the handle 6 at least in some portions from thermal radiation which falls from the cooking chamber 2 onto the door 3A. In this case, the shielding facility 22A can be positively connected to the first door support 18 and the second door support 19. However, this is not absolutely necessary. A positive connection is established by at least two connection partners, in the present case the shielding facility 22A and the door supports 18, 19, engaging in one another or behind one another. A positive connection is able to be released again without destroying the connection partners.

[0069] FIG. 4 shows a schematic perspective view of the shielding facility 22A. FIG. 5 shows a further schematic perspective view of the shielding facility 22A. Reference is made to FIGS. 4 and 5 hereinafter at the same time.

[0070] The shielding facility 22A is a bent sheet metal component. As a result, the shielding facility can be manufactured cost-effectively. However, the shielding facility 22A can also be a plastic component. The shielding facility 22A has properties which reflect thermal radiation, at least facing away from the outer pane 17. For example, the shielding facility 22A can have a reflective surface. In particular, the shielding facility 22A can have a brushed surface. The shielding facility 22A can be a stainless steel sheet. The shielding facility 22A also covers the handle 6, when viewed from the cooking chamber 2. Thus the shielding facility 22A shields the handle 6 from thermal radiation.

[0071] The shielding facility 22A comprises a plate-shaped base portion 23 which runs parallel to the inner face 20 of the outer pane 17 and is arranged spaced apart therefrom. The base portion 23 comprises a first through-hole 24 and a second through-hole 25. In this case, the through-holes 24, 25 are arranged spaced apart from one another, when viewed in the x-direction x. The through-holes 24, 25 can be configured as slots. Fastening elements 26, 27 (FIG. 2), in particular screws, can be guided through the through-holes 24, 25. The handle 6 can be connected to the door 3A by means of the fastening elements 26, 27. However, the door 3A can also be without a handle.

[0072] The fastening elements 26, 27 are guided through the through-holes 24, 25 of the base portion 23, wherein the fastening elements 26, 27 positively engage behind the shielding facility 22A. As a result, in addition to the connection to the door supports 18, 19, the shielding facility 22A is fixedly connected to the door 3A. As the shielding facility 22A in turn is positively connected to the door supports 18, 19, the first door support 18 and the second door support 19 are coupled to the outer pane 17 by means of the shielding facility 22A and the fastening elements 26, 27. In other words, even if the adhesively bonded connection fails between the door supports 18, 19 and the inner pane 17, the door supports 18, 19 remain on the door 3A and cannot be released therefrom.

[0073] The shielding facility 22A comprises a first support portion 28 which is supported on the inner face 20 of the outer pane 17. A portion 29 of the shielding facility 22A protruding in the direction of the cooking chamber 2 and facing away from the first support portion 28 adjoins the base portion 23. A second support portion 30 extending in the direction of the inner face 20 of the outer pane 17 adjoins the portion 29. The second support portion 30 also bears against the inner face 20 of the outer pane 17. A first tab 31 which can be positively engaged with the first door support 18 is provided on the second support portion 30. The shielding facility 22A also comprises a second tab 32 which can be positively engaged with the second door support 19. The tabs 31, 32 are resiliently deformable so that they can be latched into the door supports 18, 19.

[0074] As FIG. 3 shows, the base portion 23 and the portion 29 are inclined relative to one another at an angle of inclination α. The angle of inclination α is preferably more than 90°. As FIG. 2 further shows, on either side the shielding facility 22A has cut-outs 33, 34 in which the door supports 18, 19 are located. A gap 35 is provided between the shielding facility 22A and the outer pane 17. The gap 35 preferably comprises a stationary air cushion which serves for the thermal insulation. However, air can also flow through the gap 35.

[0075] The region of the door 3A in which the handle 6 is arranged is subject to strict requirements relative to maximum permitted temperatures, in particular during pyrolysis mode. Additionally, a shielding and insulation is advantageous for energy consumption requirements. These requirements can be achieved by means of the shielding facility 22A. If the door supports 18, 19 are adhesively bonded to the outer pane 17, components are prevented from falling off the door 3A, even in the case of a failure of the adhesive bond between the door supports 18, 19 and the outer pane 17, by the shielding facility 22A being positively connected to the door supports 18, 19 and the shielding facility 22A in turn being connected by means of the fastening elements 26, 27 to the outer pane 17. Additionally, the shielding facility 22A ensures that no dirt can penetrate between the outer pane 17, the intermediate panes and the inner pane. Moreover, the shielding facility 22A can also conceal technical components so that these components are not seen by a user.

[0076] The handle 6 can be attached at different heights and in different portions of the door 3A. The shielding facility 22A prevents thermal radiation from coming into contact with the door supports 18, 19, which are preferably produced from plastic, and with the outer pane 17 in an upper region of the door 3A. To this end, the shielding facility 22A can have a reflective surface. The handle 6 is prevented from having too great a temperature by the handle 6 being shielded from thermal radiation. The air cushion provided in the gap 35 brings about a thermal insulation. The shielding facility 22A is captively connected to the door supports 18, 19. This results in a pull-off force of more than 50 N. Even if the adhesive bond between the door supports 18, 19 and the outer pane 17 fails, it is ensured that no components can be released from the door 3A.

[0077] The shielding facility 22A is preferably produced from stainless steel and has a brushed surface for an improved reflective behavior. Alternatively, the shielding facility 22A can also be produced from a plastics material. In this case, a reflective surface can then be attached to the shielding facility 22A. The air cushion in the gap 35 is designed as far as possible to be closed. The locking of the shielding facility 22A to the door supports 18, 19 ensures the safety of the user, even in the case of a failure of the adhesive bond between the door supports 18, 19 and the outer pane 17. The airflow and reflective behavior improve the temperature properties, both in terms of energy consumption and in the surface temperature.

[0078] A contact pressure is achieved toward the inner face 20 of the outer pane 17 by a bulged portion being provided in the upper region of the shielding facility 22A, said bulged portion ensuring a rattle-free retention and preventing a visible gap between the shielding facility 22A and the inner face 20. Alternatively, the gap 35 can also be ventilated. To this end, recesses through which air can flow can be provided on the support portions 28, 30. Moreover, the second support portion 30 can also have a perforation. The advantages of the door 3A are a greater energy efficiency, lower front temperatures and thus compliance with strict standards, an improved cleaning result in pyrolysis mode, safety in the case of a failure of the adhesive bond between the door supports 18, 19 and the outer pane 17, as well as simple assembly.

[0079] FIG. 6 shows a schematic view of a further embodiment of a door 3B with a further embodiment of a shielding facility 22B. FIG. 7 shows a schematic sectional view of the door 3B along the cutting line VII-VII of FIG. 6. FIG. 8 shows a schematic perspective view of the shielding facility 22B. FIG. 9 shows a further schematic perspective view of the shielding facility 22B. Reference is made to FIGS. 6 to 9 hereinafter at the same time.

[0080] The shielding facility 22B differs substantially from the shielding facility 22A in that the angle of inclination α between the base portion 23 and the portion 29 is preferably 90°. In this case, a further portion 36 is provided between the portion 29 and the second support portion 30.

[0081] FIG. 10 shows a schematic plan view of a further embodiment of a door 3C with a further embodiment of a shielding facility 22C. FIG. 11 shows a schematic sectional view of the door 3C along the cutting line XI-XI of FIG. 10. FIG. 12 shows a schematic perspective view of the shielding facility 22C. FIG. 13 shows a further schematic perspective view of the shielding facility 22C. Reference is made to FIGS. 10 to 13 hereinafter at the same time.

[0082] The shielding facility 22C differs substantially from the shielding facility 22B in that the first support portion 28 has a cut-out 37, air being able to flow through said cut-out in the gap 35 between the shielding facility 22C and the outer pane 17. Moreover, the shielding facility 22C has ventilation slots 38 in the region of the portion 29. The air can flow into the gap 35 through the cut-out 37. The air can flow out again through the ventilation slots 38.

[0083] FIG. 14 shows a schematic view of a further embodiment of a door 3D with a further embodiment of a shielding facility 22D. FIG. 15 shows a schematic sectional view of the door 3D along the cutting line XV-XV of FIG. 14. FIG. 16 shows a schematic perspective view of the shielding facility 22D. FIG. 17 shows a further schematic perspective view of the shielding facility 22D. Reference is made to FIGS. 14 to 17 hereinafter at the same time.

[0084] The shielding facility 22D differs substantially from the shielding facility 22C in that no ventilation slots 38 are provided on the portion 29, but a cut-out 39 which corresponds to the cut-out 37 of the first support portion 28 and through which the gap 35 can be ventilated is provided on the second support portion 30.

[0085] Although the present invention has been described with reference to exemplary embodiments, it can be modified in many different ways.
