Furthermore, from the pamphlet U.S. 4,726,352 A a household appliance with a door and a container and a first device which is connected to the door and the container to allow rotation of the door about a first axis of rotation between a closed state and an unfolded position is known.

Furthermore, the document discloses U.S. 4,726,352 A a second mechanism cooperating with the first mechanism and the door to provide a second axis of rotation for the door spaced from the first axis of rotation. The second device is intended to provide arcuate movement of the door about the second pivot axis to thereby allow movement of the door from the unfolded position to a position below a bottom panel of the container.

In addition, the document discloses U.S. 3,327,700 A a bearing unit for coupling and decoupling a door to a domestic appliance body of a domestic appliance.

The object of the invention consists in particular in providing a generic device with improved properties with regard to a simple construction.

The object is achieved according to the invention by the features of patent claims 1 and 13, while advantageous configurations and developments of the invention can be found in the dependent claims.

The invention is based on a domestic appliance device with a domestic appliance door which has at least one outer surface which at least partially laterally delimits the domestic appliance door in at least one operating position, and which has at least one coupling unit with at least one contact area which is intended to connect the domestic appliance door to a storage unit to couple, wherein the contact area is arranged adjacent to the outer surface. The fact that the contact area is arranged “next to” the outer surface is to be understood in particular to mean that there is at least one connecting path between a point of the contact area and a point on the outer surface, which at most intersects the coupling unit. A "coupling unit" is to be understood in particular as a unit which transfers at least part of a weight force of the household appliance door to the bearing unit and/or supports part of the household appliance door so that it can rotate about an axis. A “storage unit” is to be understood in particular as a unit which, in at least one state of use, absorbs at least one load and transfers it to at least one supporting construction material. With an embodiment according to the invention, a simple construction can be achieved.

The domestic appliance device has at least one storage unit with at least one receiving area, which is intended to receive the contact area. In this way, a secure coupling of the household appliance door can be achieved.

The domestic appliance device preferably has at least one bearing unit which has at least one plain and/or roller bearing. A comfortable mobility of the household appliance door can thereby be made possible.

The domestic appliance device advantageously has at least one bearing unit which is provided to transmit a torque to the coupling unit in at least one operating sequence. A drive can thus be transmitted to the domestic appliance door in an advantageous manner.

In a preferred embodiment of the invention, the domestic appliance device has at least one guide link which is provided to guide the storage unit. As a result, a user-friendly sequence of movements of the household appliance door can be achieved when it is opened or closed.

The domestic appliance device has at least one storage space into which the domestic appliance door is at least largely inserted in at least one use state. The fact that the household appliance door is "largely" incorporated into the storage space is to be understood in particular as meaning that at least part of the household appliance door, which is at least sixty percent, in particular at least seventy-five percent and particularly advantageously at least ninety percent of a vertical extension of the household appliance door, is closed Forms state in an operating position in which storage space is arranged. In this way, a compact arrangement can be achieved.

The domestic appliance device advantageously has at least one door bearing unit, which is provided to jam the domestic appliance door to a large extent by means of a sliding movement introduce space. As a result, the household appliance door can be easily stowed away.

The domestic appliance device preferably has at least one bearing unit with at least two torque transmission means and at least one coupling means which couples the torque transmission means. In this way, a stable construction can be achieved. Advantageously, at least one of the torque transmission means is attached to the coupling means in a form-fitting manner, as a result of which assembly without tools is made possible.

Furthermore, it is proposed that the coupling unit has an axle unit. Stable mounting of the household appliance door can thus be achieved. An end section of the axle unit preferably forms the contact area. An “end section” of the axle unit is to be understood in particular as a section of the axle unit which, starting from one end of the axle unit in a main extension direction, extends in this main extension direction by less than ten percent, in particular by less than five percent and particularly advantageously by less than two percent of the length of the axis unit with respect to the main direction of extension. An “axle unit” is to be understood in particular as a unit which has at least one axle and is intended to rotatably mount at least one component. In this way, installation space can be saved, in particular along the main direction of extension of the axle unit.

In a preferred embodiment of the invention, the coupling unit has at least one guide means. A comfortable decoupling or coupling of the coupling unit can thus be achieved. The coupling unit particularly advantageously has at least one drive means. A “drive means” is to be understood in particular as a means which transfers a drive from one means to another means. A “drive” should be understood to mean, in particular, a rotary drive and/or a linear drive. In this way, a comfortable handling of the household appliance door can be achieved. In particular, the drive is transferred to a handle on the household appliance door.

In addition, it is proposed that the domestic appliance device has at least one door handle on which part of the torque transmitted by the bearing unit acts in at least one operating state. As a result, the door handle can assume ergonomically advantageous operating positions in different states of use.

Further advantages result from the following description of the drawings. Exemplary embodiments of the invention are shown in the drawing. The drawing, the description and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them into further meaningful combinations.

1 shows a domestic appliance 26 formed by an oven with a domestic appliance device that has a domestic appliance door 14 that is pivotably mounted in pivoting directions 10, 12 and has a door handle 62, which is shown in an uncoupled state. The domestic appliance 26 has an oven muffle 30 which is arranged in a domestic appliance housing 28 and encloses a useful space 16 formed by a cooking chamber from five sides. On a sixth side, specifically on a front side of the household appliance 26, the utility space 16 can be closed by the household appliance door 14. Furthermore, the household appliance 26 has a storage space 18 arranged under the oven muffle 30, into which the household appliance door 14 can be lowered, guided via a door bearing unit 20 of the household appliance device, largely by means of a pivoting movement and a subsequent sliding movement in a horizontal direction. The door bearing unit 20 has two guide means 24 which basically correspond to one another and are fixedly coupled to the lateral end faces of the household appliance door 14 in the pivoting directions 10, 12 and movably coupled to a surface extension 22 of the household appliance door 14, each with two rollers 171, 173, with only one of the two guide means 24 is shown. When the domestic appliance door 14 is closed, the surface extension 22 runs in a vertical direction when the domestic appliance 26 is arranged in an operating position. Furthermore, the door bearing unit 20 has a bearing unit 38 which is movably mounted relative to the household appliance housing 28 in order to absorb part of the weight of the household appliance door 14 .

2 shows an end of the household appliance door 14 opposite the door handle 62. In addition to a door unit 64 with the door handle 62, the household appliance door 14 has a coupling unit 34 with a contact area 36 for transferring part of the weight force, which connects the household appliance door 14 to the bearing unit 38 in an assembled state couples. The door unit 64 has an outer surface 32 which partially laterally delimits the domestic appliance door 14 in a horizontal direction in an operating position and in particular when the domestic appliance door 14 is in a closed state and when the domestic appliance door 14 is pushed into the storage space 18 . The contact area 36 is arranged next to the outer surface 32 .

The coupling unit 34, which is part of the door bearing unit 20, is formed by an axle unit 54, which has a hexagonal steel rod 66 and two bearing units 68 made of plastic in one piece, which are each positively attached to one end of the steel rod 66 and are mirror-inverted to one another . In a circumferential direction 70 of the steel rod 66, the door unit 64 is supported by the bearing units 68 so as to be rotatable about an axis 76 which runs in a horizontal direction. For this purpose, the bearing units 68 have plain bearing surfaces 84 ( 6 ), which together with corresponding slide bearing surfaces of the door unit 64 form a slide bearing. At the same time, the bearing units 68 form holding means which, in particular when the household appliance door 14 is in a closed position, absorb a weight of the household appliance door 14 and hold the household appliance door 14 in the closed position—in cooperation with other holding means. The bearing units 68 cannot rotate in the circumferential direction 70 against the steel rod 66 due to the steel rod 66 being bent. In principle, an embodiment of the axle unit 54 in which the steel rod 66 is dispensed with is also conceivable. It is also conceivable that the bearing units 68 are designed in one piece with the steel rod 66 and are also made of steel.

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

3 shows a schematic representation of the domestic appliance 26 without the domestic appliance door 14 in a lateral front view. The bearing unit 38 is movably mounted relative to the household appliance housing 28 by two guide links 44 of the household appliance 26 . The guide links 44, which are designed to be mirror images of one another, delimit part of the storage space 18 on a right and a left side in a front view of the domestic appliance. 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 has roller bearings 42 designed as ball bearings with steel outer rings ( 4 ), Which formed in the insertion of the household appliance door 14 on the guide made of polypropylene and long glass fibers roll backdrop 44 and be guided in this way. The roller bearings 42 are attached to two torque transmission 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 can be coupled in the main extension directions 78 of the coupling means 52 with the aid of recesses 51 ( 5 ) are attached. 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, when the domestic appliance door 14 is in the installed state, the elevations 72 of the bearing units 68 and thus the contact areas 36 accommodates. The receiving area 40 is partially delimited by a contact surface 49 of the torque transmission means 48, 50 which, when the household appliance door 14 is in the installed state, bears against the contact area 36 and transmits a torque to the contact area 36 and thus to the coupling unit 34, which torque occurs when the household appliance door 14 moves exerts a torque on the coupling unit 34, by which the coupling unit 34 is rotated relative to the door unit 64. In the transmission of the torque, a surface part of the elevation 72 which is opposite the flat surface part 74 and which in this case bears against a contact surface 46 of the torque transmission means 48, 50 also acts. In the installed state of the household appliance door 14, the elevations 72 ( 2 ) as bearing means 86 by transferring part of the weight of the domestic appliance door 14 or the door unit 64 to the contact surface 49 and to a lower boundary surface 80 of the torque transmission means 48, 50, which partially bounds the receiving area 40 downwards in the vertical direction. In this way, the torque transmission means 48, 50 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 storage unit 68, in that the contact area 36 slides on the contact surface 46 when the household appliance door 14 is uncoupled from the storage unit 38 and thereby guides the household appliance door 14. The contact area 36 consequently acts as a guide surface 82. Maintenance or cleaning of the household appliance door 14 can advantageously be carried out by decoupling.

7 shows a schematic representation of the household appliance door 14 that has been detached from the storage unit 38, with an intermediate pane and an inner pane 141 (see 1 ) of the door unit 64 have been removed. The door handle 62 is attached to rollers 111, 113 which support it for rotation about an axis 92. In an operating position, the axis 92 runs in a horizontal direction. A torque transmission means 94, 95 is fastened to each of the rollers 111, 113 in such a way that a torque can be transmitted to the rollers 111, 113 by means of the torque transmission means 94, 95, which torque rotates the door handle 62 about the axis 92. Conversely, a torque can be transmitted to the torque transmission means 94, 95 by means of the door handle 62. Furthermore, the torque transmission means 94, 95 each have a cable 181, which is deflected by one hundred and eighty degrees through the roller 111 and 113, respectively. One bolt 115 is fastened to one of the torque transmission means 94, 95 (see FIG 6 ) and engages in a receiving area 116 of the bearing units 68, as a result of which the torque transmission means 94, 95 are fastened to the bearing units 68 in a form-fitting manner. The torque transmission means 94, 95 run in grooves 127 of the bearing units 68 and are thus fastened in a form-fitting manner along the axis 76.

The door unit 64 is designed as a profile rail door and has two profile rails 121, 123. The bearing units 68 are partially arranged in recesses 163 in the profile rails 121, 123. The recesses 163 are delimited by bearing surfaces of the profile rails 121, 123, which are not shown in detail. When the household appliance door 14 is opened, the slide bearing surfaces 84 of the bearing units 68 slide on the corresponding bearing surfaces of the profile rails 121, 123. Furthermore, the rollers 111, 113 and thus the door handle 62 are rotatably mounted by means of the profile rails 121, 123. On the profile rails 121, 123 a fastening means 98 relative to the profile rails 121, 123 is fastened immovably. An eyelet 125 of the fastening means 98, which is designed in one piece and acts as a pane fastening means for the inner pane 141 and the intermediate pane in a fully assembled state, has a first and a second fastening area 100, 104, which are immovable relative to the axis 92.

The door unit 64 also has a first and a second spring means 96, 102, which are designed as coil springs. A first end of the first spring means 96 is hooked into the first attachment area 100 , a first end of the second spring means 102 is hooked into the second attachment area 104 . Eyelets 117, 119 of the torque transmission means 94, 95 are also attached to two ends of the cable pull 181. A second end of the spring means 96 is also attached to the eyelet 117 . The spring means 96 is arranged 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 arranged between the eyelet 125 and the bearing unit 68 not. Main extension directions of the spring means 96, 102 are parallel to the surface extension 22. A section 129 of the torque transmission means 94, which is attached to the eyelet 117, runs parallel and directly next to an outer pane 133 of the door unit 64. A second section 131 runs parallel to the first section 129 and parallel to the inner pane 141 of the door unit 64 and is arranged directly next to the inner pane 141 . Section 129 is arranged between section 131 and outer pane 133 .

The first spring means 96 has a significantly greater spring rate than the second spring means 102. The spring means 96, 102 keep the cable 181 taut in an assembled state. By rotating 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, when the bearing units 68 rotate about the axis 76 relative to the profile rails 121, 123, a torque is transmitted to the door handle 62 by means of the torque transmission means 94, 95 and the rollers 111, 113. A rotation of the profile rails 121, 123 relative to the storage units 68 takes place when the household appliance door 14 is opened and closed.

8th shows schematically the closed state of the household appliance door 14. The first spring means 96 has the smallest deflection compared to all other possible operating positions. A main extension direction 135 of the door handle 62 perpendicular to the axis 92 is arranged perpendicular to the sections 129 , 131 and to the outer pane 133 . When the household appliance door 14 is opened, the torque transmission means 48, 50 transmit by means of the contact surfaces 46, 49 (see 5 ) a torque on the elevation 72 and thus on the bearing unit 68, since the force exerted by the spring means 96 on the torque transmission means 94 and the weight of the door handle 62 pushes the elevation 72 against the contact surfaces 46, 49. In this way, when the household appliance door 14 is opened, the bearing units 68 remain stationary relative to the bearing unit 38 and rotate about the axis 76 relative to the profile rails 121, 123. The bearing units 68 transmit a torque and thus a drive to the torque transmission means 94, 95, which is why the bearing unit 68 is identical to a functional means 106 designed as a drive means 60. During opening, the torque transmission means 94, 95 and the rollers 111, 113 transmit the drive to the door handle 62, which causes the main direction of extension 135 of the door handle to run essentially in a horizontal direction in every open position of the door unit 64 when the domestic appliance 26 is in an operating position is arranged. Also, upon opening, the spring means 96 is stretched while the spring means 102 contracts.

The bearing unit 68 and the torque transmission means 48 form a locking unit 108. In a state of use in which the household appliance 26 is fully assembled and in which the user only uses the door handle 62 to open or close the household appliance door 14, the locking unit 108 is in an unlock state ( 10 ), in which the domestic appliance door 14 can be decoupled from the storage unit 38 in a partially open position when the surface extension 22 (see 1 ) forms an angle of about twenty degrees with a vertical. For decoupling, the household appliance door 14 is first pivoted in one of the pivoting directions 10, 12 into the partially open position. A user or fitter can then attach the household appliance door 14 to the outer surfaces 183 of the profile rails 121, 123, which form surfaces of the profile rails 121, 123 and partially delimit the household appliance door 14 laterally in a frontal view, and to the outer surfaces 185, 187 of the inner pane 141 and the Outer pane 133, which partially delimit the outer pane 133 or the inner pane 141 laterally in the front view, hold tight and move the domestic appliance door 14 in a straight line in the direction of the surface extension 22 upwards. As a result, the elevations 72 slide through indentations 162 of the torque transmission means 48, 50 ( 5 ) and are thereby removed from the receiving areas 40, as a result of which the household appliance door 14 is decoupled from the storage unit 38. During uncoupling and after uncoupling, the storage unit 38 can optionally be fixed by a locking unit 161 in a position in which the storage unit 38 is arranged immediately before uncoupling. If this option is used, after the household appliance door 14 has been uncoupled, guide surfaces 143, 145 of the storage unit 38 make it easier to couple the household appliance door 14 to the storage unit 38 by guiding the elevations 72 when they are brought into the receiving area 40 and thus also the storage units 68. During the coupling, the rollers 171, 173 of the guide means 24 also move (see 1 ) in lateral grooves 175 of the household appliance door 14, which partially delimit the household appliance door 14 laterally in an operating position ( 2 ). A groove base 177 of the groove 175 has an indentation 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 bearing units 68, so that a movable coupling of the household appliance door 14 to the guide means 24 by the bearing units 68 remains unimpaired.

The locking unit 108 is also provided to prevent the household appliance door 14 from being removed from the storage unit 38 when the household appliance door 14 is in an at least partially open position. If, for example, a user or fitter brings the household appliance door 14 into a position in which the surface extension 22 encloses an angle of approximately twenty degrees with a vertical and moves the door handle 62 upwards in the direction of the surface extension 22, the door handle 62 rotates by means of 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 profile rails 121, 123 about the axis 76. As a result, the elevations 72 move into a locking position ( 11 ). The screwing in of the elevations 72 is guided by guide surfaces 157, 159, which are formed by surface parts of the torque transmission means 48, 50 delimiting the receiving areas 40. One of the guide surfaces 159 is formed by the undercut 147 . The turning in of the elevations 72 is stopped in that two surface parts 149, 151 of the elevations 72 abut two surface parts 153, 155 of the torque transmission means 48, which partially delimit the receiving area 40. If the surface parts 149, 151 of the elevations 72 are in contact with the surface parts 153, 155 of the torque transmission means 48, then the elevations 72 are in the locking position. If a user then tries to move the domestic appliance door 14 away from the storage unit 38 in the direction of the surface extension 22 , this is prevented by the elevations 72 hitting the undercuts 147 , as a result of which the elevations 72 remain in the receiving areas 40 .

12 shows a schematic representation of the household appliance door 14 in an open position with the inner pane 141, which the usable space 16 (see 1 ) in a closed position of the household appliance door 14 is closed. The elevations 72 are introduced into the receiving areas 40 and the locking unit 108 is in the unlocked state. If an operator attempts to decouple the household 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, the outer pane 133 acts as a locking element since the torque transmission means 48, 50 are connected to the Abut the outer pane and thereby prevent the elevations 72 from being removed from the receiving areas 40 .

When assembling the household appliance door 14, the profile rails 121, 123 are first glued onto the outer pane 133 ( 6 ). To assemble the coupling unit 34 , the bearing units 68 are slipped onto the ends of the steel rod 66 and pressed together 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 bearing units 68 are then in their assembled position. The bearing units 68 each have a recess 165 . To fix the bearing units 68 and the steel rod 66, which acts as a coupling means 169, in the mounted position, fastening means 167 designed as steel clamps are inserted through the recesses 165 and thus latched, so that the fastening means 167 are fastened to the bearing units 68. The fastening means 167 bear against the ends of the steel rod 66, so that a relative movement and in particular a relative movement of the bearing units 68 towards one another is prevented. In principle, it is also conceivable that the bearing units 68 are attached to the steel rod 66 in a different way or that the coupling unit 34 is mounted before the profile rails 121, 123 are glued on. It is also conceivable that one of the bearing units 68 is fastened by means of the steel clamp and the other bearing unit 68 is fastened to the steel rod 66 in a different way or is formed in one piece with it. A further alternative possibility for fastening the bearing units 68 by means of the steel clamps would also be to arrange spring elements, such as compression springs, in receiving areas of the bearing units 68, into which the steel rod 66 is inserted in a mounted state, which, when the bearing units 68 be compressed. By compressing these spring elements, assembly of the coupling unit 34 is also possible with profile rails 121, 123 already glued on, in that the bearing units 68 are pressed together and the spring elements are thus compressed. In an assembled state, the bearing units 68 would be pushed apart by these spring elements and thus attached to the profile rails 121, 123. As a further alternative, the steel bar 66 could have a different number of edges. In particular, the steel rod 66 can also be round, in which case the bearing units 68 would be able to rotate relative to one another about the axis 76 . In the case of an embodiment of the coupling unit 34 without the steel rod 66, the bearing units 68 would have to be attached to the profile rails 121, 123 in some other way. This could, for example, by snapping the bearing units 68 into the Pro filrails 121, 123 or by inserting the bearing units 68 into the profile rails 121, 123 and attaching retaining rings to the bearing units 68, which fasten the bearing units 68 to the profile rails 121, 123 along the axis 76 in a form-fitting manner.

The guide means 24, which is rotatably mounted about a horizontal axis 193, and the bearing unit 38 form a household appliance door bearing unit 191, which supports the household appliance door 14 pivotably about the axis 193 ( 1 ). The locking unit 161 is intended to fix the domestic appliance door bearing unit 191 in a pivoted 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 to move the locking means 195 from an initial position ( 13 ) to a detent position ( 14 ) to move, in which the locking means detects the household appliance door bearing unit 191 in the pivoted position. The actuating means 197 is designed as an adjusting bracket. In the locking position, locking means 195 engages in a recess 201 of locking means 200 of locking unit 161, which is attached to guide means 24 in such a way that guide means 24 and locking means 200 rotate relative to one another about an axis 204, which is parallel to axis 193 and when the guide means 24 rotates together with the guide means 24, are rotatable. With respect to the directions of rotation about the axis 193, the locking means 195 is on a guide element 203 fixed to the housing (see 16 ) attached to 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 specific rotational position.

Furthermore, the locking means 200 is provided to transmit a spring force to the guide means 24 . A spiral spring 207 is suspended from the locking means 200, which expands when the household appliance door 14 is opened and stores part of the potential energy that the household appliance door 14 has in a closed state and thus serves as an energy storage unit.

The torque transmission means 48, 50 are also parts of the household appliance door bearing unit 191. They each have an indentation 205 ( 5 ) into which a locking means 189 designed as a tooth ( 1 ) of the guide means 24 engages in pivoted positions of the household appliance door 14 and in particular in a pivoted position of the household appliance door 14 in which the locking means 195 is arranged in the locked position. As a result of the locking means 189 engaging in the indentation 205, the guide means 24 and the bearing unit 38 are essentially immovable relative to one another. If the locking means 195 is consequently in the locking position when the domestic appliance is in a mounted state, then the domestic appliance door bearing unit 191 is fixed in a pivoted removal position. In this pivoted position, the household appliance door 14 can be uncoupled from the household appliance door bearing unit 191 by the straight-line movement in the upward direction of the surface extension 22 .

If the household appliance door 14 is in a partially open position, an operator or fitter can insert a coin into a groove 206 of an actuating means 199 ( 15 ), which is designed as a pivot, penetrate the locking unit 161 and, starting from an initial position in which the household appliance door 14 can be opened and closed, rotate it by ninety degrees ( 13 and 14 ). If the domestic appliance door bearing unit 191 is in a pivoted position which differs from the removal pivoted position, the actuating means 197 is tightened by this turning of the actuating means 199 and thereby expanded, since the actuating means 197 is fastened to the actuating means 199. Due to the tightening of the actuating means 197, the locking means 195, which is attached to the actuating means 197, is pressed in the vertical direction downwards against a sliding surface 202 of the locking means 200, which is arranged on an upper side of the locking means 200. To engage the locking means 195 in the recess 201, the operator or fitter pivots the household appliance door 14 in the pivoting directions 10, 12 (see 1 ), locking means 195 sliding on sliding surface 202 until domestic appliance door bearing unit 191 is in the pivoted removal position and locking means 195 snaps into recess 201 as a result of pressure exerted downwards by actuating means 197 on locking means 195. The domestic appliance door 14 can then be uncoupled from the storage unit 38 and the guide means 24 by the linear movement. If a user wants the uncoupled household appliance door 14 in an operating position such. B. in the closed position, the rollers 171, 173 are placed in the groove 175 and the elevations 72 in the receiving areas 40 and the actuating means 199 is turned back by one hundred and eighty degrees, whereby the locking means 195 is pushed back into the starting position and the household appliance door 14 can be pivoted into the closed position, for example.

16 shows part of the domestic appliance device with the guide element 203 fixedly mounted on the housing, on which the guide means 24 is fastened so that it can rotate about the axis 193 . The guiding element 203 has recesses 208 designed as elongated holes, which the locking means 195 hold when shifting from the starting position ( 13 ) to the locked position ( 14 ) and leads back again.

The domestic appliance 26 also has a domestic appliance door guide device. 17 shows a one-piece first door guide means 209 of the domestic appliance door guide device. In order to guide the domestic appliance door 14 , the domestic appliance 26 has a further door guide means 209 which is designed to be mirror-inverted in comparison to the first door guide means 209 . The two door guides 209 laterally delimit the storage space 18 in a front view of the domestic appliance (see FIG 3 ). The door guide means 209 each form a guide link, which is identical to the guide link 44 or is formed as a mirror image of it and which has a guide surface 210 made of plastic with long glass fibers for guiding the bearing unit 38 . The guide slot 44 has a plurality of areas 256, 258, 260, which partially delimit the storage space 18 laterally when the domestic appliance is in the installed state. The first area 256 is arranged on a front area of the domestic appliance and runs obliquely upwards when the domestic appliance is in an operating position. The second area 258 is arranged in a central area 258 of the household appliance between the front area and the rear of the household appliance and runs in a horizontal direction. The third area 260 partly laterally delimits the storage space 18 in a rear area and runs obliquely downwards.

When the household appliance door 14 is brought into the storage space 18, the household 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 ( 3 ), which is formed from a block formed from polyurethane. The door guide means 209 has a receiving area 214 on an end area of the guide slot 44 facing the rear of the domestic appliance. The damping means 212 latches into a latching means 216 of the door guide means 209 which is arranged in the receiving area 214 and is partially arranged in the receiving area 214 . At the end of an insertion process of the household appliance door 14 into the storage space 18, the torque transmission means 50 (see 4 ) to the damping means 212 and transfers 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 part of the door guide means 209, which partially surrounds the guide slot 44, has a rib structure 218, which is formed by a pattern with honeycomb cells 230. Furthermore, the door guide means 209 forms a receiving area 228 which is directly adjacent to a front side of the storage space. In a mounted state, the actuating means 199 is arranged in the receiving area 228 and is rotatably supported by the door guide means 209 (see FIG 15 ).

The guide means 24, which forms a bearing means 222 and allows the domestic appliance door 14 to pivot, is rotatably supported by the door guide means 209. In a state of wear of the rotatable mounting of the bearing means 222, the bearing means 222 could have a play 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 ( 18 ) of the door guide means 209, the bearing means 222 can perform a secure rotary motion despite the clearance. An outer area 234 of the bearing means 222 slides on the sliding surface 220 ( 19 ), the bearing means 222 being 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 a side of the door guide means 209, which faces an outside area of the domestic appliance in an installed state, the door guide means 209 has a fastening means 224 for fastening a cable 236 of a light of the domestic appliance ( 20 ). The fastening means 224 is designed as a clamping means and clamps the cable 236 firmly to the rib structure 218 in a mounted state.

Parts of the household appliance housing 28 are screwed directly to the door guide means 209 ( 3 ). These are in particular a floor 238, side walls 240, an intermediate floor 242, which partially delimits the storage space 18 at the top, a decorative panel and a pilaster strip. The base 238 has a fold 244 which extends upwards in an operating position and encompasses the door guide means 209 . The bevel 244 is screwed to the door guide means 209 at three points 246 . The three points 246 are evenly distributed over the depth of the domestic appliance.

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

If the household 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 in the event of an impact of the household appliance 26 are passed on to the door guide means 209 . These parts are, for example, the side walls 240 in a rear area of the household appliance 26, the intermediate floor 242 and the side walls 240 in a central area of the household appliance 26, and an oven flange 252, the pilaster strip and a drip channel 250 in a front area of the household appliance 26, which the bottom 238 is formed. The door guide means 209 has an elevation 254 ( 17 ), which engages in the drip channel 250 in a mounted state.

The door guide means 209 is produced in an injection molding process.
