FIG. 1 shows a household appliance 26 formed by an oven with a domestic appliance device having a pivotally mounted in pivoting directions 10, 12 household appliance door 14 with a door handle 62, which is shown in a disconnected state. The household appliance 26 has an oven muffle 30, which is arranged in a household appliance housing 28 and encloses a usable space 16 formed by a cooking chamber on five sides. On a sixth side, namely on a front side of the household appliance 26, the useful space 16 can be closed by the appliance door 14. Furthermore, the household appliance 26 a below the oven muffle 30 arranged storage space 18, in which the household appliance door 14 is guided over a door storage unit 20 of the home appliance device to a large extent by means of a pivoting movement and a subsequent sliding movement in a horizontal direction retractable. The door storage unit 20 has two basically corresponding, each with lateral end faces of the appliance door 14 in the pivoting directions 10, 12 fixed and in a surface extension 22 of the appliance door 14 movably coupled guide means 24 with two rollers 171, 173, wherein only one of the two guide means 24 is shown. The surface extension 22 runs in a closed direction when the appliance door 14 is closed in a vertical direction when the household appliance 26 is arranged in a Bedienpösition. Furthermore, the door storage unit 20 for receiving a portion of the weight of the appliance door 14 a relative to the appliance housing 28 movably mounted storage unit 38.

FIG. 2 In addition to a door unit 64 with the door handle 62, the domestic appliance door 14 for transmitting the part of the weight of a coupling unit 34 with a contact portion 36 which the domestic appliance door 14 in an assembled state with the storage unit 38th coupled. The door unit 64 has an outer surface 32, which laterally delimits the domestic appliance door 14 in an operating position and in particular in a closed state of the appliance door 14 and when the household appliance door 14 is pushed into the storage space 18 in a horizontal direction. In addition to the outer surface 32, the contact region 36 is arranged.

The coupling unit 34, which is a part of the door storage unit 20, is formed by an axle unit 54, which has a hexagonal steel bar 66 and two integral plastic storage units 68, which are each attached positively to one end of the steel bar 66 and mirror-inverted , In a circumferential direction 70 of the steel bar 66, the door unit 64 is rotatably supported by the bearing units 68 about an axis 76 which extends in a horizontal direction. For this purpose, the bearing units 68 slide bearing surfaces 84 ( FIG. 6 ), which together with corresponding sliding bearing surfaces of the door unit 64 form a sliding bearing. At the same time, the bearing units 68 form retaining means which, in particular in a closed position of the household appliance door 14, absorb a weight force of the domestic appliance door 14 and hold the domestic appliance door 14 - in cooperation with other holding means - in the closed position. The bearing units 68 are in the circumferential direction 70 against the steel rod 66 due to a fold of the steel rod 66 non-rotatable. In principle, an embodiment of the axle unit 54 is also conceivable in which the steel rod 66 is dispensed with. It is also conceivable that the bearing units 68 are formed integrally with the steel rod 66 and are also made of steel.

The contact region 36 is formed by an end section 56 of the axis unit 54 (FIG. FIG. 2 ). For this purpose, the bearing units 68 have elevations 72 with flat surface parts 74, which extend mainly in a direction perpendicular to the axis 76. A surface of the projections 72 and in particular the surface parts 74 form the contact region 36.

FIG. 3 shows a schematic representation of the household appliance 26 without the appliance door 14 in a lateral frontal view. The bearing unit 38 is movably supported by two guide slots 44 of the household appliance 26 relative to the domestic appliance housing 28. The guide slots 44, which are formed mirror-inverted to each other, limit a portion of the storage space 18 in a front view of the domestic appliance on a right and a left side. When the household appliance door 14 is pushed into the storage space 18, it is guided indirectly by the guide slots 44. For this purpose, the bearing unit 38 designed as a ball bearing bearings 42 with steel outer rings ( FIG. 4 ), which roll when inserting the appliance door 14 on the guide slot 44 formed from polypropylene and long glass fibers and are guided in this way. The rolling bearings 42 are attached to two torque transmitting means 48, 50 of the bearing unit 38. Furthermore, the bearing unit 38 has a coupling means 52 formed by a rod, at the ends of which the torque transmission means 48, 50 are arranged in main directions of extension 78 of the coupling means 52 with the aid of recesses 51 (FIG. FIG. 5 ) are plugged. A movement of one of the torque transmission means 48, 50 automatically leads to a movement of the other torque transmission means 48, 50 due to the coupling means 52. The torque transmission means 48, 50 each have a receiving area 40, which in a mounted state of the appliance door 14, the elevations 72 of the storage units 68th and thus the contact areas 36 receives. The receiving region 40 is partially delimited by a contact surface 49 of the torque-transmitting means 48, 50, which rests against the contact region 36 in an assembled state of the appliance door 14 and transmits a torque to the contact region 36 and thus the coupling unit 34, which occurs when the appliance door 14 moves on the coupling unit 34 exerts a torque by which the coupling unit 34 is rotated relative to the door unit 64. In the transmission of torque also acts a surface part of the elevation 72 lying opposite the flat surface part 74, which rests against a contact surface 46 of the torque transmission means 48, 50. In the assembled state of the appliance door 14, the projections 72 (FIG. 2) act as bearing means 86, by applying part of the weight of the appliance door 14 and the door unit 64 to the abutment surface 49 and to a lower boundary surface 80 of the torque transmitting means 48, 50 the recording area 40 partially limited in the vertical direction down, transmitted. The torque transmission means 48, 50 thus function as holding means 90, which in particular hold the closed household appliance door 14 in position.

Furthermore, the elevation 72 forms a further functional means 88-namely, a guide means 58-of the bearing unit 68 in that the contact area 36 slides on a bearing surface 46 when the household appliance door 14 is uncoupled from the storage unit 38, thereby guiding the appliance door 14. Accordingly, the contact region 36 functions as a guide surface 82. A maintenance or cleaning of the appliance door 14 can advantageously take place by the uncoupling.

FIG. 7 shows a schematic representation of the decoupled from the storage unit 38 household appliance door 14, wherein an intermediate disc and an inner pane 141 (see FIG. 1 ) of the door unit 64 have been removed. The door handle 62 is attached to rollers 111, 113 which rotatably support it about an axis 92. In an operating position, the axis 92 extends in a horizontal direction. On the rollers 111, 113, respectively, a torque transmission means 94, 95 is fixed such that by means of the torque transmission means 94, 95 each have a torque on the rollers 111, 113 is transferable, which rotates the door handle 62 about the axis 92. Conversely, a torque can be transmitted to the torque transmitting means 94, 95 by means of the door handle 62. Furthermore, the torque transmission means 94, 95 each have a cable pull 181, which is deflected by one hundred and eighty degrees through the rollers 111 and 113, respectively. In each case a bolt 115 is attached to one of the torque transmission means 94, 95 (see FIG. 6 ) and engages in a receiving region 116 of the bearing units 68, whereby the torque transmission means 94, 95 are positively secured to the bearing units 68. The torque transmission means 94, 95 extend in grooves 127 of the bearing units 68 and are thus secured in a form-fitting manner along the axis 76.

The door unit 64 is designed as a profiled rail door and has two profiled rails 121, 123. The bearing units 68 are partially arranged in recesses 163 of the profile rails 121, 123. The recesses 163 are bounded by non-illustrated bearing surfaces of the rails 121, 123. When the household appliance door 14 is opened, the sliding bearing surfaces 84 of the bearing units 68 slide against the corresponding bearing surfaces of the profiled rails 121, 123. Furthermore, the rollers 111, 113 and thus the door handle 62 are rotatably supported by means of the profiled rails 121, 123. On the profile rails 121, 123 each one fastening means 98 is fixed relative to the rails 121, 123 immovably. An eyelet 125 of the fastener 98, which is integrally formed and, in a fully assembled state, functions as a disc attachment means for the inner disc 141 and the washer, has first and second attachment portions 100, 104 which are immovable relative to the axle 92.

The door unit 64 also has a first and a second spring means 96, 102, which are formed as coil springs. A first end of the first spring means 96 is hooked to the first attachment portion 100, a first end of the second spring means 102 is hooked to the second attachment portion 104. At two ends of the cable 181 eyelets 117, 119 of the torque transmission means 94, 95 are further attached. A second end of the spring means 96 is further attached to the eyelet 117. The spring means 96 is disposed between the eyelet 125 and the roller 113. A second end of the second spring means 102 is attached to the eyelet 119. The second spring means 102 is disposed between the eyelet 125 and the bearing unit 68. Main extension directions of the spring means 96, 102 are parallel to the surface extension 22. A portion 129 of the torque transmitting means 94, which is attached to the eyelet 117, runs parallel and directly adjacent to an outer disk 133 of the door unit 64. A second portion 131 is parallel to the first portion 129 and parallel to the inner pane 141 of the door unit 64 and is arranged directly next to the inner pane 141. The partial section 129 is arranged between the partial section 131 and the outer plate 133.

The first spring means 96 has a significantly greater spring stiffness than the second spring means 102. The spring means 96, 102 keep the cable 181 stretched in an assembled state. By means of a rotation of the door handle 62 relative to the profile rails 121, 123 about the axis 92, a torque is transmitted to the bearing units 68 with the aid of the rollers 111, 113 and the torque transmission means 94, 95.

In addition, upon rotation of the bearing units 68 about the axis 76 relative to the rails 121, 123 by means of the torque transmitting means 94, 95 and the rollers 111, 113, a torque is transmitted to the door handle 62. A rotation of the profile rails 121, 123 relative to the bearing units 68 takes place when opening and closing the appliance door 14.

FIG. 8 schematically shows the closed state of the appliance door 14. The first spring means 96 has in this case compared to all other possible operating positions a smallest deflection. A main extension direction 135 of the door handle 62 perpendicular to the axis 92 is in this case arranged perpendicular to the subsections 129, 131 and to the outer disk 133. When the household appliance door 14 is opened, the torque transmission means 48, 50 are transmitted by means of the abutment surfaces 46, 49 (see FIG FIG. 5 ) a torque on the survey 72 and thus on the bearing unit 68, since the force exerted by the spring means 96 on the torque transmitting means 94 and the force of gravity of the door handle 62, the survey 72 against the contact surfaces 46, 49 presses. In this way, the bearing units 68 remain stationary when opening the appliance door 14 relative to the bearing unit 38 and rotate relative to the rails 121, 123 about the axis 76. The bearing units 68 transmit thereby by means of the receiving portion 116 and the bolt 115, a torque and thus a drive to the torque transmission means 94, 95, which is why the bearing unit 68 is identical to a trained as a drive means 60 functional means 106. When opened, the torque transmitting means 94, 95 and the rollers 111, 113 transfer the drive to the door handle 62, which causes the main extension direction 135 of the door handle in each opening position of the door unit 64 to extend substantially in a horizontal direction when the domestic appliance 26 is in an operating position is arranged. Upon opening, furthermore, the spring means 96 is stretched as the spring means 102 contracts.

The storage unit 68 and the torque transmitting means 48 form a locking unit 108. In a use state in which the home appliance 26 is fully assembled and in which the user uses the door handle 62 only to open or close the appliance door 14, the locking unit 108 is in FIG a release state ( FIG. 10 ), in which the appliance door 14 in a partially open position of the storage unit 38 can be decoupled when the surface extension 22 (see FIG. 1 ) includes an angle of about twenty degrees with a vertical. To a decoupling the household appliance door 14 is first pivoted in one of the pivoting directions 10, 12 in the partially open position. Thereafter, a user or a fitter can the home appliance door 14 on outer surfaces 183 of the rails 121, 123, which surfaces of the rails 121, 123 and the home appliance door 14 in a front view partially limit laterally, and on outer surfaces 185, 187 of the inner pane 141 and the Outer disk 133, which partially laterally delimit the outer disk 133 and the inner disk 141 in the front view, and hold the household appliance door 14 in a straight line in the direction of the surface extension 22 upwards. In this way, the elevations 72 slide through indentations 162 of the torque transmission means 48, 50 (FIG. 5) and are thereby removed from the receiving areas 40, as a result of which the appliance door 14 is uncoupled from the storage unit 38. During uncoupling and after uncoupling, the bearing unit 38 can optionally be detected by a locking unit 161 in a position in which the bearing unit 38 is arranged immediately before uncoupling. If this option is used, after disconnecting the household appliance door 14, guide surfaces 143, 145 of the storage unit 38 facilitate coupling the household appliance door 14 to the storage unit 38, by guiding the raised portions 72 when introduced into the receiving area 40 and thus also the storage units 68. Furthermore, in the coupling operation, the rollers 171, 173 of the guide means 24 (see FIG FIG. 1 ) in lateral grooves 175 of the household appliance door 14, which partially delimit the household appliance door 14 in an operating position laterally ( FIG. 2 ). A groove bottom 177 of the groove 175 has a recess 179, in which the elevation 72 is arranged. When the household appliance door 14 is coupled, the rollers 171, 173 move into the groove 175 and past the storage units 68, so that a movable coupling of the domestic appliance door 14 to the guide means 24 by the storage units 68 remains unimpaired.

The locking unit 108 is further provided to prevent removal of the appliance door 14 from the storage unit 38 in an at least partially open position of the appliance door 14. For example, a user or a fitter brings the appliance door 14 in a position in which the surface extension 22 forms an angle of about twenty degrees with a vertical, and moves the door handle 62 in the direction of the surface extension 22, the door handle 62 rotates by means a coupling unit 139, which is formed by the rollers 111, 113, the torque transmission means 94, 95 and the bolts 115, the bearing units 68 relative to the rails 121, 123 about the axis 76. As a result, the protrusions 72 move to a locking position (FIG. FIG. 11 ), behind undercuts 147 of the torque transmitting means 48, 50, which are formed by formed by the torque transmission means 48, 50 boundaries of the receiving areas 40, screwing. The screwing in of the elevations 72 is guided by guide surfaces 157, 159 which are formed by the receiving areas 40 delimiting surface parts of the torque transmission means 48, 50. One of the guide surfaces 159 is formed by the undercut 147. The screwing in of the elevations 72 is stopped in that two surface parts 149, 151 of the elevations 72 abut against two surface parts 153, 155 of the torque transmission means 48, which partially delimit the receiving region 40. When the surface portions 149, 151 of the projections 72 abut against the surface portions 153, 155 of the torque transmitting means 48, the projections 72 are in the locking position. If a user then attempts to move the appliance door 14 in the direction of the surface extension 22 away from the storage unit 38, this is prevented by the projections 72 abutting the undercuts 147, as a result of which the projections 72 remain in the receiving areas 40.

FIG. 12 shows a schematic representation of the appliance door 14 in an open position with the inner pane 141, which the utility space 16 (see FIG. 1 ) closes in a closed position of the appliance door 14. The protrusions 72 are inserted into the receiving areas 40 and the locking unit 108 is in the unlocked state. If an operator attempts to decouple the appliance door 14 from the storage unit 38 in the open position by attempting to guide the elevations 72 out of the receiving areas 40 through the indentations 162, then the outer pane 133 acts as a locking element, since the torque transmission means 48, 50 contact the Outer disk abut and this prevents removal of the projections 72 from the receiving areas 40.

When mounting the appliance door 14, first the profile rails 121, 123 are glued to the outer pane 133 ( FIG. 6 ). To mount the coupling unit 34, the bearing units 68 are attached to the ends of the steel rod 66 and compressed so far until the bearing units 68 abut the ends of the steel rod 66. A first of the bearing units 68 is then inserted into one of the recesses 163 of one of the profile rails 121, 123. By means of a movement of the second of the bearing units 68 and a movement of the steel rod 66, the second bearing unit 68 is inserted into the remaining recess. The steel bar 66 and the bearing units 68 are then in their mounted position. The bearing units 68 each have a recess 165. to Fixing the bearing units 68 and the steel rod 66, which acts as a coupling means 169, in the mounted position fasteners 167 designed as steel clamps are inserted through the recesses 165 and engaged therewith, so that the fastening means 167 are fastened to the bearing units 68. The fastening means 167 abut against the ends of the steel rod 66, so that a relative movement and in particular a relative movement of the bearing units 68 to each other is prevented. In principle, it is also conceivable that the bearing units 68 are fastened in a different manner to the steel bar 66 or that the coupling unit 34 is mounted prior to the gluing of the profile rails 121, 123. Furthermore, it is conceivable that one of the bearing units 68 is fastened by means of the steel clamp and the other bearing unit 68 is fastened in another way to the steel rod 66 or is formed integrally therewith. A further alternative possibility for fastening the bearing units 68 by means of the steel clamps would also be to arrange in receiving areas of the bearing units 68, in which the steel rod 66 is inserted in an assembled state, spring elements, such as compression springs, which upon compression of the bearing units 68 be compressed. By compressing these spring elements, an assembly of the coupling unit 34 is possible even with already glued rails 121, 123 by the bearing units 68 compressed and the spring elements are thus compressed. In an assembled state, the bearing units 68 would be pushed apart from these spring elements and thus attached to the rails 121, 123. As a further alternative, the steel bar 66 could also have a different number of edges. In particular, the steel rod 66 can also be designed to be round, in which case the bearing units 68 would be rotatable relative to each other about the axis 76. In one embodiment of the coupling unit 34 without the steel rod 66, the bearing units 68 would otherwise be attached to the rails 121, 123. This could, for example, by locking the bearing units 68 in the rails 121, 123 or by inserting the bearing units 68 in the rails 121, 123 and securing circlips to the bearing units 68, which the bearing units 68 form fit to the rails 121, 123 along the Attach axle 76, done.

The guide means 24, which is rotatably mounted about a horizontal axis 193, and the storage unit 38 form a domestic appliance door storage unit 191 which supports the household appliance door 14 pivotably about the axis 193 ( FIG. 1 ). The locking unit 161 is provided to fix the home appliance door storage unit 191 in a pivotal position. For this purpose, the locking unit 161 has a locking means 195 designed as a bolt and an elastic actuating means 197, which is provided for locking the locking means 195 from a starting position (FIG. FIG. 13 ) in a locking position ( FIG. 14 ) in which the locking means detects the home appliance door bearing unit 191 in the pivotal position. The actuating means 197 is designed as an adjusting bracket. In the locking position, the locking means 195 engages a recess 201 of a locking means 200 of the locking unit 161, which is fixed to the guide means 24, that the guide means 24 and the locking means 200 relative to each other about an axis 204 which is parallel to the axis 193 and is rotated at a rotation of the guide means 24 with the guide means 24 are rotatable. The locking means 195 is with respect to the directions of rotation about the axis 193 on a housing-fixed guide member 203 (see FIG. 16 ) of the home appliance device. Therefore, when the locking means 195 is in the locking position, rotation of the guide means 24 about the axis 193 is prevented and the guide means 24 is thus fixed in a certain rotational position.

Furthermore, the locking means 200 is provided to transmit a spring force to the guide means 24. On the locking means 200, a coil spring 207 is mounted, which is expanded upon opening of the appliance door 14 and a part of the potential energy, which the appliance door 14 has in a closed state, stores and thus serves as an energy storage unit.

The torque transmission means 48, 50 are also parts of the domestic appliance door storage unit 191. They each have a recess 205 (FIG. FIG. 5 ) into which a locking means 189 (FIG. FIG. 1 ) of the guide means 24 in pivotal positions of the appliance door 14 and in particular in a pivot position of the appliance door 14, in which the locking means 195 is arranged in the locking position, engages. By the engagement of the locking means 189 in the recess 205, the guide means 24 and the bearing unit 38 are substantially immovable relative to each other. Accordingly, if the locking means 195 is in the locking state in a mounted state of the domestic appliance, the domestic appliance door storage unit 191 is fixed in a take-out swinging position. In this pivoting position, the domestic appliance door 14 can be decoupled from the domestic appliance door storage unit 191 by the rectilinear movement in the direction of the surface extension 22.

If the appliance door 14 is in a partially open position, an operator or fitter for fixing the appliance door storage unit 191, for example with the aid of a coin, can insert into a groove 206 of an actuating means 199 (FIG. FIG. 15 ), which is designed as a pivot, the locking unit 161 penetrate and this starting from a starting position, in which an opening and closing of the appliance door 14 is possible to rotate by ninety degrees ( Figures 13 and 14 ). If the home appliance door storage unit 191 is in a swing position different from the take-off swing position, the actuator 197 is cocked and thereby expanded by this rotation of the operation means 199 since the operation means 197 is fixed to the operation means 199. Due to the tightening of the actuating means 197, the locking means 195, which is attached to the actuating means 197, in a vertical downward direction against a sliding surface 202 of the locking means 200, which is arranged on an upper side of the locking means 200 is pressed. For a locking of the locking means 195 in the recess 201 pivots the operator or fitter the appliance door 14 in the pivot directions 10, 12 (see FIG. 1 ), wherein the locking means 195 slides on the sliding surface 202 until the domestic appliance door storage unit 191 is in the withdrawal pivot position and the locking means 195 in the recess 201 due to a pressure which the actuating means 197 on the locking means 195 downwardly engages. Thereafter, the home appliance door 14 can be decoupled by the linear movement of the bearing unit 38 and the guide means 24. Will a user the disconnected household appliance door 14 in an operating position such. B. bring in the closed position, the rollers 171, 173 are introduced into the groove 175 and the projections 72 in the receiving areas 40 and the actuating means 199 again turned back by one hundred eighty degrees, whereby the locking means 195 is moved back to the starting position and the appliance door 14 is pivotable, for example, in the closed position.

FIG. 16 shows a portion of the home appliance device with the fixed to the housing guide member 203 to which the guide means 24 is rotatably mounted about the axis 193. The guide element 203 has slots formed as recesses 208, which the locking means 195 during the displacement of the starting position ( FIG. 13 ) in the locking position ( FIG. 14 ) and back again.

The home appliance 26 further includes a home appliance door guide device. FIG. 17 shows an integrally formed first door guide means 209 of the household appliance door guide device. To guide the appliance door 14, the household appliance 26 has a further door guide means 209, which is mirror-inverted compared to the first door guide means 209. The two door guide means 209 limit in a frontal view of the household appliance, the storage space 18 laterally (see FIG. 3 ). The door guide means 209 each form a guide slot, which is identical to the guide slot 44 or is mirror-inverted to this and which has a guide surface made of plastic with long glass fibers 210 for guiding the bearing unit 38. The guide slot 44 has a plurality of areas 256, 258, 260, which limit the storage space 18 partially laterally in an assembled state of the domestic appliance. The first area 256 is arranged on a front area of the household appliance and runs obliquely upward in an operating position of the household appliance. The second area 258 is arranged in a middle area 258 of the domestic appliance between the front area and the rear side of the household appliance and runs in a horizontal direction. The third area 260 limits the storage space 18 in a rear area partially laterally and extends obliquely downwards.

When introducing the household appliance door 14 into the storage space 18, the domestic appliance door 14 is at least partially braked by the household appliance door guide device. For this purpose, the domestic appliance door guide device has a damping means 212 (FIG. 3), which is formed from a cuboid formed from polyurethane. At an end region of the guide slot 44 facing the rear of the household appliance, the door guide means 209 has a receiving area 214. The damping means 212 is engaged on a latching means 216 of the door guide means 209, which is arranged in the receiving region 214, and is partially arranged in the receiving region 214. At the end of an insertion process of the appliance door 14 into the storage space 18, the torque transmission means 50 (see FIG. 4 ) to the damping means 212 and transmits kinetic energy to the damping means 212, which partially converts the energy into heat and partially passes it on to the door guide means 209, which is thereby slightly deformed.

A portion of the door guide means 209 partially surrounding the guide slot 44 has a rib structure 218 formed by a honeycomb cell pattern 230. Furthermore, the door guide means 209 forms a receiving area 228 which directly adjoins a front side of the storage space. In a mounted state is in the Receiving portion 228, the actuating means 199 arranged and rotatably supported by the door guide means 209 (see FIG. 15 ).

The guide means 24, which forms a bearing means 222 and allows pivoting of the appliance door 14, is rotatably supported by the door guide means 209. In a wear condition of the rotatable mounting of the bearing means 222, the bearing means 222 could have a margin in a lateral, horizontal direction away from the storage space 18 in comparison to a new state of the domestic appliance. Due to a sliding surface 220 ( FIG. 18 ) of the door guide means 209, the bearing means 222 despite the margin perform a safe rotational movement. In this case, an outer region 234 of the bearing means 222 slides on the sliding surface 220 (FIG. FIG. 19 ), wherein the bearing means 222 is supported by the sliding surface 220. The sliding surface 220 is a segment of a cylinder jacket whose axis of symmetry corresponds to the axis 193.

On one side of the door guide means 209, which in an assembled state faces an outer region of the domestic appliance, the door guide means 209 has a fastening means 224 for fastening a cable 236 to a lighting of the domestic appliance ( FIG. 20 ). The fastening means 224 is designed as a clamping means and clamps the cable 236 in a mounted state on the rib structure 218.

Parts of the household appliance housing 28 are screwed directly to the door guide means 209 ( FIG. 3 ). These are in particular a floor 238, side walls 240, an intermediate floor 242, which limits the storage space 18 partially upwards, a trim panel and a Lisene. The bottom 238 has a fold 244, which expands in an operating position upwards and surrounds the door guide means 209. The fold 244 is screwed to the door guide means 209 at three points 246. The three points 246 are evenly distributed over a depth dimension of the household appliance.

At an area 248 adjoining the front of the domestic appliance, the door guide means 209 has an indentation at one end section of the guide slot 44, through which the bearing unit 38 can be removed from the guide slot 44. Before such removal of the bearing unit 38, the coupling of the bearing unit 38 with the locking means 189 designed as a tooth must be canceled.

If the domestic appliance 26 is lifted and dropped onto the floor 238 or an edge of the floor 238, forces acting on parts of the household appliance 26 are transmitted to the door guide means 209 in the event of a collision of the household appliance 26. These parts are in a rear portion of the household appliance 26, for example, the side walls 240, in a central region of the domestic appliance 26, the intermediate bottom 242 and the side walls 240 and in a front region of the domestic appliance 26, a baking pipe flange 252, the Lisene and a drip tray 250, which of the bottom 238 is formed. The door guide means 209 has an elevation 254 ( FIG. 17 ), which engages in a mounted state in the drip groove 250.
