Definitions
- the invention relates to an operational module for a door of a domestic appliance, especially a cooker, to a corresponding domestic appliance door as well as to a domestic appliance with the door.
- a switchable glass door for domestic appliances is known from DE 297 22 024 U1, in which a ‘glass keypad’ is integrated on or into the glass door.
- the control panel is the transparent glass door itself.
- the keypad can comprise an LCD display or a monitor.
- a control strip can be dispensed with.
- the evaluation electronics necessary for the operational control unit is accommodated in a reduced-temperature insulated area of the oven. The disadvantage in this case is that the unit is comparatively expensive to manufacture and repair. In addition the electronics makes it difficult for the users with poor sight and limited tactile capabilities to operate the device. In particular the longevity of the electrical and thin-film-components is also not guaranteed.
- Pushbutton elements are also known from DE 299 19 792 U1 of which the operating surface is embodied from a glass pane.
- a microwave oven is known from DE 30 37 277 A1 in which electrically controllable operational facilities for manual operation are accommodated on the door. Also disclosed are keypads located behind a front surface of a door, which in accordance with this device can advantageously extend up to the front of the oven compartment opening. Since the door occupies the whole of the front of the oven, a separate control panel can be omitted.
- a microwave oven is known from DE 38 29 913 A1 in which switching, control and/or display means are built into the oven compartment door and are located behind a front window.
- DE 201 03 517 U1 describes a cooking appliance with functionalized oven door, in which the contacts are applied to the door in the form of foils and in particular displays are able to be projected onto the at least partly transparent door, such as in a so-called head-up display for example.
- the display and/or operating element can also be fitted detachably to the cooking appliance door.
- WO 97/26486 discloses an oven with operational controls integrated into a handle.
- a cooking appliance door is known from EP 1 120 606 A2 which has control switches and display panels distributed in its door, which fit flush with the front of the door. This is comparatively expensive to manufacture and to wire.
- the object of the invention is to provide an option for simple and low-cost manufacturing and for simple installation, easy maintenance and improved handling of operational controls.
- the operational module has at least one operational control and is able to be inserted at least partly into a recess in the cooking appliance door.
- An operational control in this case can be a defined constructional or functional group which forms a part of a whole and can be modified or exchanged without interventions or modifications being needed to the rest of the system (cf. bibliographisches Institut & F. A. Brockhaus A G, Mannheim; Spektrum Akademischer Verlag GmbH, Heidelberg, 2003); This can expediently be a housing able to be separated from the domestic appliance door with at least the built-in operational control/operational controls.
- this operational module has the advantage of needing fewer and simpler installation steps and of being easier to replace.
- a greater diversity of switching elements knocks, rocker switches
- the operational module can expediently also feature associated electrics and/or electronics as well as suitable communication means for data transmission with other components, e.g. cables, cable connections, evaluation and/or control electronics, wireless transmission units or similar.
- the respective operational module advantageously features a part which projects outwards (viewed from inside the domestic appliance), which projects outwards from the door surface after being built into the door, and also a part able to be inserted into the recess which preferably projects backwards from the part able to be inserted into the recess. This enables the thickness or mounting depth of the door to be reduced and better operability is able to be achieved
- the insertable part of the operational module especially to accommodate electrical and/or electronic components whereas the projecting part especially includes operational controls.
- Such an arrangement makes it possible to provide a large control panel which can also jut out sideways (upwards, downwards, to the left and/or to the right in an overhead view of the door) beyond the recess, whereas the recess itself can be kept expediently small to provide a barrier against heat.
- Provision of a part of the operational module (viewed towards the door) jutting out sideways beyond the recess or beyond the part of the operational module that can be inserted into the recess can be generally advantageous for reasons of heat dissipation and better operability.
- a front door panel e.g. an outer or front pane of the domestic appliance door, especially with a seal.
- the operational module For further sealing of a side of the appliance door, especially with recesses open to the side, it is advantageous for the operational module to feature a cover plate which is suitable for covering at least one part, preferably the part of the side edge of the domestic appliance opened by the recess. In this case it is also expedient for a seal to the side edge of the appliance door to already be present in the area of the cover plate.
- cover plate can be advantageous for example, for easier replacement and for better attachment of the operational module for the cover plate to project in a sideways direction beyond the area adjoining it of the (upper, lower, left-hand and/or right-hand) side edge.
- the optimization of the heat shielding is especially useful for doors with a fully-glazed surface—possibly except for a narrow frame.
- the operational module prefferably feature at least one display panel, e.g. a pixel-controllable LCD display, as well as at least one rotary switch or knob.
- the at least one rotary switch it is especially expedient for the at least one rotary switch to be arranged below the display panel.
- buttons are positioned to the side of the display panel, especially if the buttons are positioned to the left or to the right of the display panel, particularly if the buttons are positioned symmetrically to the left or to the right of the display panel.
- buttons are pushbuttons since they then essentially form one surface plane with the display panel.
- buttons and the display panel are covered by a common cover, especially a common pane, e.g. a plastic pane.
- an operational module in which the display panel and/or the buttons are accommodated in the area of the outwards-projecting part lying opposite the part able to be inserted into the recess, since control and evaluation electronics can be brought nearer to these operational controls, especially the display panel.
- the at least one rotary switch is also advantageous for the at least one rotary switch to be arranged on the part jutting out sideways beyond the recess, and especially to be able to be placed on a door panel, since in this way the size and position of the rotary switch is not restricted by the recess and the recess can be kept small. This applies especially since associated evaluation electronics is not needed, or the rotary switch can be simple and small by comparison with the control electronics.
- the part projecting outwards is expediently at least partly tapered at an edge area, typically from the front surface to the rear, e.g. back towards the front door panel. It is then useful for maintaining a large packing volume of the operational module for the part jutting out sideways beyond the recess, to be tapered, especially back towards the front door panel.
- the part jutting out sideways beyond the recess can expediently be tapered in one or more directions (e.g. on the left, on the right and/or upwards or downwards). It is especially advantageous for the operational module to be tapered, e.g. touched, on a side facing away from the domestic appliance door.
- the operational controls e.g. rotary switches, can also be accommodated in an area which is partly tapered and partly not tapered.
- the switches are arranged in pairs symmetrically around a central axis of the operation device.
- the central axis can be perpendicular to the edge of the appliance and can especially be a vertical central axis.
- the operational module ( 2 , 33 ) has at least one attachment element in its rear area, especially in the part to be inserted in the recess, especially a threaded hole for accepting a screw.

- the insertable part of the operational module especially accepts electrical and/or electronic components, while the part projecting outwards especially includes the operational controls.
- the recess can be made at different depths in the domestic appliance door as required. To minimize the effect of a recess on an appliance door, only the front door panel, e.g. the front pane, needs to be provided with the recess. Depending on requirements, e.g. the internal structure of the door, the embodiment of the operational module or cooling requirements, the recess can also pass through further door elements, e.g. further door panes, partitions or areas of insulation. In this case it is also possible for the recess to pass through the entire appliance door, so that the part of the operational module able to be inserted into the recess can be pushed through the door.
- further door elements e.g. further door panes, partitions or areas of insulation.
- the recess can for example include or represent a cutout open to the side of at least the front door panel; this is advantageous for simpler installation.

- Ventilation does not have to have the form shown in the exemplary embodiments; thus for example the air can be guided around the cooking chamber in other ways, ventilation inlets and outlets can be positioned elsewhere, and so forth. Ventilation can also be dispensed with; the door can then even manage without a hollow inner space.
- modules can be inserted into a recess, and as an alternative or in addition a number of recesses each with one operational module can be used.

Abstract
Description
- The invention relates to an operational module for a door of a domestic appliance, especially a cooker, to a corresponding domestic appliance door as well as to a domestic appliance with the door.
- A switchable glass door for domestic appliances is known from DE 297 22 024 U1, in which a ‘glass keypad’ is integrated on or into the glass door. In this case the control panel is the transparent glass door itself. The keypad can comprise an LCD display or a monitor. A control strip can be dispensed with. The evaluation electronics necessary for the operational control unit is accommodated in a reduced-temperature insulated area of the oven. The disadvantage in this case is that the unit is comparatively expensive to manufacture and repair. In addition the electronics makes it difficult for the users with poor sight and limited tactile capabilities to operate the device. In particular the longevity of the electrical and thin-film-components is also not guaranteed.
- Pushbutton elements are also known from DE 299 19 792 U1 of which the operating surface is embodied from a glass pane.
- A microwave oven is known from
DE 30 37 277 A1 in which electrically controllable operational facilities for manual operation are accommodated on the door. Also disclosed are keypads located behind a front surface of a door, which in accordance with this device can advantageously extend up to the front of the oven compartment opening. Since the door occupies the whole of the front of the oven, a separate control panel can be omitted. - A microwave oven is known from
DE 38 29 913 A1 in which switching, control and/or display means are built into the oven compartment door and are located behind a front window. - DE 201 03 517 U1 describes a cooking appliance with functionalized oven door, in which the contacts are applied to the door in the form of foils and in particular displays are able to be projected onto the at least partly transparent door, such as in a so-called head-up display for example. The display and/or operating element can also be fitted detachably to the cooking appliance door.
- WO 97/26486 discloses an oven with operational controls integrated into a handle.
- A cooking appliance door is known from
EP 1 120 606 A2 which has control switches and display panels distributed in its door, which fit flush with the front of the door. This is comparatively expensive to manufacture and to wire. - The object of the invention is to provide an option for simple and low-cost manufacturing and for simple installation, easy maintenance and improved handling of operational controls.
- The object is achieved by an operational module as claimed in
claim 1, a domestic appliance door as claimed inclaim 24 and a domestic appliance as claimed inclaim 25. Advantageous embodiments emerge in particular from the subclaims, individually or in combination. - The operational module has at least one operational control and is able to be inserted at least partly into a recess in the cooking appliance door.
- An operational control in this case can be a defined constructional or functional group which forms a part of a whole and can be modified or exchanged without interventions or modifications being needed to the rest of the system (cf. Bibliographisches Institut & F. A. Brockhaus A G, Mannheim; Spektrum Akademischer Verlag GmbH, Heidelberg, 2003); This can expediently be a housing able to be separated from the domestic appliance door with at least the built-in operational control/operational controls.
- Compared to distributed individual operational controls, this operational module has the advantage of needing fewer and simpler installation steps and of being easier to replace. Compared to elements arranged behind the door front there is the advantage of the door itself possibly being thinner since the housing can project outwards; In addition a greater diversity of switching elements (knobs, rocker switches) is possible, which can also be easier to operate. Compared to control units accommodated on the door there is also the advantage of more reliable attachment, e.g. by clamping to the door, a less protruding design and a simpler connection to other device components, e.g. a power supply.
- As well as operational controls (switches, knobs, buttons, sliders etc.) and/or display elements (LED displays, alphanumeric displays such as full-pixel LED panels etc.) the operational module can expediently also feature associated electrics and/or electronics as well as suitable communication means for data transmission with other components, e.g. cables, cable connections, evaluation and/or control electronics, wireless transmission units or similar.
- To reduce heat being taken up from the door or an inner chamber of the domestic appliance—e.g. a cooking chamber—the respective operational module advantageously features a part which projects outwards (viewed from inside the domestic appliance), which projects outwards from the door surface after being built into the door, and also a part able to be inserted into the recess which preferably projects backwards from the part able to be inserted into the recess. This enables the thickness or mounting depth of the door to be reduced and better operability is able to be achieved
- In this case it is useful for the insertable part of the operational module especially to accommodate electrical and/or electronic components whereas the projecting part especially includes operational controls. Such an arrangement makes it possible to provide a large control panel which can also jut out sideways (upwards, downwards, to the left and/or to the right in an overhead view of the door) beyond the recess, whereas the recess itself can be kept expediently small to provide a barrier against heat.
- Provision of a part of the operational module (viewed towards the door) jutting out sideways beyond the recess or beyond the part of the operational module that can be inserted into the recess can be generally advantageous for reasons of heat dissipation and better operability.
- For reasons of sealing the inside of the door against the environment it is advantageous for the part jutting out sideways (i.e. left-side, right-side, upwards and/or downwards) beyond the recess to be placed on a front door panel, e.g. an outer or front pane of the domestic appliance door, especially with a seal.
- For further sealing of a side of the appliance door, especially with recesses open to the side, it is advantageous for the operational module to feature a cover plate which is suitable for covering at least one part, preferably the part of the side edge of the domestic appliance opened by the recess. In this case it is also expedient for a seal to the side edge of the appliance door to already be present in the area of the cover plate.
- It can be advantageous for example, for easier replacement and for better attachment of the operational module for the cover plate to project in a sideways direction beyond the area adjoining it of the (upper, lower, left-hand and/or right-hand) side edge.
- The aforementioned applies especially for doors which cover a side of the domestic appliance without use of a control panel. The optimization of the heat shielding is especially useful for doors with a fully-glazed surface—possibly except for a narrow frame.
- To optimize the function of the operational module it is expedient for the greater part of the operational controls, especially all operational controls, to be accommodated in a single operational module. Only a single recess in the door is then required and thus only one insertion and attachment process. Repair by exchanging the entire operational module is then easier.
- It is advantageous for simple operation for the operational module to feature at least one display panel, e.g. a pixel-controllable LCD display, as well as at least one rotary switch or knob. In this case it is especially expedient for the at least one rotary switch to be arranged below the display panel.
- For improved, especially simple and intuitive user guidance it is useful for buttons to be positioned to the side of the display panel, especially if the buttons are positioned to the left or to the right of the display panel, particularly if the buttons are positioned symmetrically to the left or to the right of the display panel.
- It is also advantageous for the buttons to be pushbuttons since they then essentially form one surface plane with the display panel.
- It is advantageous for example for improved user friendliness and for improved cleanability for the buttons and the display panel to be covered by a common cover, especially a common pane, e.g. a plastic pane.
- Especially advantageous is an operational module in which the display panel and/or the buttons are accommodated in the area of the outwards-projecting part lying opposite the part able to be inserted into the recess, since control and evaluation electronics can be brought nearer to these operational controls, especially the display panel.
- It is also advantageous for the at least one rotary switch to be arranged on the part jutting out sideways beyond the recess, and especially to be able to be placed on a door panel, since in this way the size and position of the rotary switch is not restricted by the recess and the recess can be kept small. This applies especially since associated evaluation electronics is not needed, or the rotary switch can be simple and small by comparison with the control electronics.
- To avoid users catching themselves on an edge of the operational module the part projecting outwards is expediently at least partly tapered at an edge area, typically from the front surface to the rear, e.g. back towards the front door panel. It is then useful for maintaining a large packing volume of the operational module for the part jutting out sideways beyond the recess, to be tapered, especially back towards the front door panel. In this case the part jutting out sideways beyond the recess can expediently be tapered in one or more directions (e.g. on the left, on the right and/or upwards or downwards). It is especially advantageous for the operational module to be tapered, e.g. touched, on a side facing away from the domestic appliance door. The operational controls, e.g. rotary switches, can also be accommodated in an area which is partly tapered and partly not tapered.
- For ease of operation it is advantageous for the switches to be arranged in pairs symmetrically around a central axis of the operation device. The central axis can be perpendicular to the edge of the appliance and can especially be a vertical central axis.
- For secure attachment the operational module (2, 33) has at least one attachment element in its rear area, especially in the part to be inserted in the recess, especially a threaded hole for accepting a screw.
- The object is also achieved by a domestic appliance door, especially a cooker door, specifically an oven door with at least one recess for accepting at least one of the operational modules described above, into which an operational module can be inserted. The door can especially be a door for cookers, especially for ovens.
- It is advantageous for the operating module to be inserted partly into the recess of the door and to partly project outwards. Expediently the insertable part of the operational module especially accepts electrical and/or electronic components, while the part projecting outwards especially includes the operational controls.
- The recess can be made at different depths in the domestic appliance door as required. To minimize the effect of a recess on an appliance door, only the front door panel, e.g. the front pane, needs to be provided with the recess. Depending on requirements, e.g. the internal structure of the door, the embodiment of the operational module or cooling requirements, the recess can also pass through further door elements, e.g. further door panes, partitions or areas of insulation. In this case it is also possible for the recess to pass through the entire appliance door, so that the part of the operational module able to be inserted into the recess can be pushed through the door.
- The recess can for example include or represent a cutout open to the side of at least the front door panel; this is advantageous for simpler installation. Alternatively the recess can be surrounded by material of at least the front panel on all sides. The recess can also be open on two sides. It is also possible for the recess to be shaped differently in different layers of the door, e.g. as a recess opening to the side in the front pane and as an enclosed recess in a pane lying behind this.
- The part projecting outwards can also extend sideways in any direction (i.e. to the left side, to the right side, upwards and/or downwards) beyond the part to be inserted into the recess.
- It can also be useful for the door to have a full glass front into which the recess is made. With a full glass door in particular it is useful for the door handle to be integrated into the side of the door.
- The object is also achieved by a domestic appliance, especially a cooking appliance, which features the door described above with at least one operational module described above suitable for use therein. This applies especially to domestic appliances without a separate control panel.
- In the figures below the invention is described by schematic exemplary embodiments. These exemplary embodiments do not restrict the invention which is defined by the scope of the claims. The same parts are identified throughout by the same reference symbols.
-
FIG. 1 shows a sketch viewed from outside at an angle of a built-in oven with operational module; -
FIG. 2 shows the front side of the operational module fromFIG. 1 viewed from an angle; -
FIG. 3 shows the rear of the operational module fromFIGS. 1 and 3 viewed from an angle; -
FIG. 4 shows the operational module fromFIG. 1 to 3 in a cross-sectional view from the side; -
FIG. 5 shows the front of an operational control viewed at an angle: -
FIG. 6 shows, in a schematic overhead view of the front, a number of options for embodying the oven door. -
FIG. 1 shows anoven door 1 of an oven, into which anoperational module 2 is inserted. Theoven door 1 completely covers the front side of the oven, so that the latter does not have to have a separate control panel. On its outer side or front side theoven door 1 has a full-surfaceouter glass pane 4 as its front door panel held only by anarrow metal frame 3. For heat insulation the oven door I further features aninner glass pane 5 with an inner door area being formed betweenpanes panel 6 is inserted into this inner door area, which is used for eye protection and for air flow guidance. A cutout 7 in thepanel 6 defines a viewing window. Inserted into thestrip 6 areventilation slots 8 in the lower part for introducing fresh air. The upper air outlet vent holes are not shown here. Theoven door 1 can be opened and closed by ahandle 9 on one side. - The
operational module 2 projects forwards and upwards from theouter glass pane 4. Its front side lies partly in parallel to the surface of theouter glass pane 4, but is tapered in a lower edge area towards theouter glass pane 4. The projecting sides of theoperational module 2 are not tapered, nor is the part projecting upwards. -
FIG. 2 shows theoperational module 2 fromFIG. 1 in greater detail, viewed at an angle from the front. In acommon housing 10 theoperational module 2 comprises a display unit in the form of a pixel-controlledLCD display 11, to the left and to the right of which are accommodated three touch-sensitive buttons 12.LCD display 11 andbuttons 12 are covered by acommon plastic pane 13. To the side below theLCD display 11 are positioned tworotary knobs 14 as further switches. Theknobs 14 in this case are also located below thearea 15 to be inserted in the recess on apart 16 projecting out from theappliance door 1. Thepart 16 projecting out from the appliance door is partly tapered downwards; theknobs 14 are located partly in the tapered area, partly in the non-tapered area. On its upper edge theoperational module 2 has acover plate 17 that can cover one edge of an appliance door and here also encloses one edge of the plastic pane. - The
display 11, thebuttons 12 and theknobs 14 are arranged symmetrically in relation to a vertical center line I-I. -
FIG. 3 shows theoperational module 2 fromFIGS. 1 and 2 viewed from behind at an angle. Thepart 15 to be inserted into the recess haselectrical terminals 30 as itselectronics outlet area 24. Aseal 25 surrounding the rear edge area is clearly visible in the diagram. In the area of the rotary switches 14 theseal 25 rests against the front door front and seals the inside of the door and theoperational module 2 from their surroundings. In the upper rear edge area, which is covered here by theupper cover plate 17, theseal 25 passes just below thecover plate 17, as also shown below inFIG. 5 . It can be seen that theplastic pane 13 is located approximately in front of thepart 15 able to be inserted into the recess. - For attaching it to the
appliance door 1, theoperational module 2 has two threadedholes 21 integrated into thehousing 10, into which attachment screws (not shown) are able to be screwed. -
FIG. 4 shows theoperational module 2 fromFIG. 1 to 3 from the side in a sectional view along the line I-I fromFIG. 2 , built into acooker door 1. The projectingarea 16 can be seen, as indicated by thearrow 31 pointing to the right, as well as thepart 15 able to be inserted into arecess 28 in theouter pane 4, as indicated by thearrow 31 pointing to the left. The projectingpart 16 includes the operational controls such as theknob 14, theLCD display 11 accommodated behind aplastic pane 13 as well as the touch-sensitive buttons (not shown), which are all accommodated in acommon housing 10. Thepart 15 able to be inserted into therecess 28 includeselectronics 29 for evaluating the signals of theoperational controls 14; also present in this housing is aloudspeaker 31 controlled by theelectronics 29, for example for creating clicking noises when theknobs 14 are turned. - It can be easily seen that the part belonging to the outwards-projecting
part 16 of theoperational module 2 projecting down beyond therecess 28 that is indicated by the associatedarrow 31 rests with itsseal 25 on theouter pane 4. The rotary switches 14 thus also rest on the front door front, if necessary at a slight distance from it. Thepart 27 projecting beyond therecess 28 shows thetaper 32 towards the outerfront pane 4. The rotary switches 14 are partly arranged in the surface in parallel to thefront glass pane 4, partly in thetapered part 32. - It can also be seen that the
upper cover plate 17 covers a part of the side edge of thecooker door 1 and also seals against it by means of theseal 25. Thecover plate 17 projects upwards beyond the delimiting upper side edge of thecooker door 1 which in this cutout is formed by anedge finishing strip 26. - The
recess 28 into which theoperational module 2 is inserted is only made in theouter glass pane 4; asecond glass pane 5 behind this does not have a recess for accommodating theoperational module 2. Therecess 28 here is a recess open on its upper side. - The operational
module mounting space 20 is defined by theouter glass pane 4, the second,inner glass pane 5, theedge finishing strip 26 and thepartition 22 provided for thermal decoupling from the lower area of doorinner space 18, which is sealed off by theoperational module 2. Located in the operationalmodule mounting space 20 are theelectronics housing part 24 with theelectronics 29 which is able to be inserted into therecess 28. - The
door ventilation opening 19 is provided for further thermal decoupling of operationalmodule mounting space 20 andinner door space 19, through which warm air can escape from the area opposite the cooking compartment. Furthermore theventilation opening 23 is present in the edge finishing strip, through which the rear of the operationalmodule mounting space 20 is cooled. -
FIG. 5 shows a furtheroperational module 33 with adisplay unit 11 and touch-sensitive buttons 12, but this module now hasseparate knobs 34. Thelower edge 35 of thisoperational module 33 is apart 36 projecting outwards and also extends downwards to one side over thepart 15 to be inserted, so that here too thedisplay 11 andbuttons 12 are arranged in front of the outer panel of a door. The lower edge likewise has a taperedpart 37. - Alternatively the rotary switches 34 can also be integrated to the side into the
operational module 33, i.e., incorporated into the housing. Then for example the part jutting out sideways to the left or to the right beyond the recess can accept a rotary switch in each case and can also be tapered, e.g. downwards and/or to the left or right. - In a further embodiment for example the cover plate can be fitted at the bottom and the operational module can be tapered at the top, especially to accommodate it on an underside of the door.
-
FIG. 6 shows a sketch of an overhead view from the front of anouter door panel 38 with five selected typical forms of the arrangement ofrecess 39 to 44, which are marked by the dotted and dashed areas A1 to A6. The areas A1 to A6 can be present in an actual version individually, a number of times or in combination, and can be at any suitable location on the oven door. In the figure the location of the thermal delimiting walls which defines the operationalmodule mounting space 20 here, e.g. strips, ribs, insulating walls etc. in the space within the door is indicated by dashed lines, whereas the outer limit of the operational module on the outer side of thefront door panel 38 is shown by a dashed line. - In the area A1 the
recess 39 is made in the outerfront pane 4 open at the top, so that the module can for example be inserted from above. In this case it can also protrude upwards. The associated thermal delimitation shown as a dotted line in the inner space of the door surrounds the recess except for the upper section and thus also defines the operationalmodule mounting space 20. The outer projecting part of the operational module extends to the left and the right here as well as downwards beyond the thermal delimitation or the operational module mounting space, if required upwards as well. - If better thermal shielding is required, the operational module mounting space can be chosen large enough for the projecting part of the operational module for example in the sideways direction (to the left, to the right, upwards and/or downwards) to jut out beyond the recess, but not to jut out beyond the operational module mounting space.
- In area A2 the projecting part of the operational module only juts out downwards beyond the recess and the operational module mounting area, in area A3 it only juts out sideways.
- Area A4 has a structure which is functionally similar to that of area A1, but is now in the left side of the
door panel 38. Here the operational module can also project sideways beyond the edge of thefront door panel 38. - Area A5 differs from areas A1 through A4 in that the
recess 43 is completely enclosed by theouter pane 38; the projecting part of the operational module extends sideways here in all directions beyond the recess and beyond the operational module mounting area. - Area A6 corresponds in its structure to areas A1 and A4, the recess 47 is arranged open towards the lower side of the
door 38, thus the cover plate is also arranged expediently on the lower side of the operational module. - The figure also shows that a number of recesses (here: Areas A1 through A3) are separated by a common thermal separator or divider from the hot area of the
door 38. - The invention is not restricted to the features of the above embodiments. Although its use in hot/cold doors is especially advantageous, the invention can be applied to all domestic appliances equipped with a door.
- Also for example the door can be equipped with other walls, made of metal, plastic etc. for example. The walls also do not have to be transparent. With transparent panes materials other than glass can be used.
- In addition the ventilation does not have to have the form shown in the exemplary embodiments; thus for example the air can be guided around the cooking chamber in other ways, ventilation inlets and outlets can be positioned elsewhere, and so forth. Ventilation can also be dispensed with; the door can then even manage without a hollow inner space.
- Furthermore a number of modules can be inserted into a recess, and as an alternative or in addition a number of recesses each with one operational module can be used.
