Description

Household appliance and appliance door

The present invention relates to a household appliance with a usable space which can be closed by means of a door having a door handle, and with a storage space into which the door can be displaced by means of a guide system, which guide system has at least one guide element assigned to the door, which in one of the Household appliance associated slide track is guided.

DE 199 06 913 discloses a generic household appliance with a door that closes a usable space in the household appliance. An opening with a guide system arranged therein is formed in a horizontal plane below the usable space. The door can be pushed into the opening via the guide system.

The object of the present invention is to provide a household appliance or a household appliance door which can be operated in an ergonomically advantageous manner.

The object of the present invention is achieved by a household appliance with the features of patent claim 1. According to the characterizing part of patent claim 1, the door handle is assigned at least one control gear which, when the door is pivoted in a first pivoting direction, pivots the door handle in a second pivoting direction opposite to the first pivoting direction. As a result, a spatial orientation of the door handle can be maintained essentially independently of a pivoting position of the door. The door handle is thus always directed towards an operator, regardless of a door pivot position. When the door is open, it is therefore no longer necessary to reach around the edge of the door to reach the door handle.

According to an advantageous embodiment of the invention, the control gear interacts directly with the guide element of the door in order to transmit a drive movement to the control gear. A movement of the guide element in the slide track can thus serve as a drive movement for the control gear. According to a further development of the invention, the guide element can be realized by a guide roller that rolls when it moves in the link path and transmits a rotary movement to the control gear.

Instead of the rotary movement mentioned above, according to a further embodiment of the invention, the guide element can be pivotably mounted with respect to the door. When moving in the slide path, there is therefore a pivoting movement between the guide element and the door, which is transmitted as a drive movement to the control gear.

According to a preferred embodiment of the invention, the control gear can have a drive part which transmits a movement, for example a pivoting movement or a rotary movement, to the control gear.

The guide element has an actuating lever for transmitting a swiveling movement serving as drive movement to the control gear. The adjusting lever is in a positive connection with the drive part of the control gear. As a result, the guide element is pivotally connected in the manner of a hinge with respect to the control gear.

An adjustable locking element which can be adjusted between a locking position and a release position can advantageously be assigned to the control gear. In the release position, the locking element can release the positive connection between the drive part of the control gear and the guide element. As a result, the door for cleaning can be removed from the household appliance in a simple manner.

In order to achieve an opening or closing movement of the door that is ergonomically advantageous for the operator, the door is additionally pivoted about a hinge axis fixed to the housing for storage in the slide tracks. Since the hinge axis is designed to be fixed to the housing, the design effort involved is low compared to a moving hinge axis.

According to a particularly advantageous embodiment, the slide track has an insertion section in which the door is guided in an essentially horizontal plane is. A horizontal movement of the door can be achieved by means of the insertion section. Guiding the door into the storage space or out of the storage space is therefore made possible for the operator in a simple and ergonomically favorable manner.

In order to achieve a horizontal movement of the door that is ergonomically particularly advantageous for the operator, the hinge axis fixed to the housing is arranged essentially at the height of the insertion section of the slide track.

In a particularly advantageous embodiment of the control gear, the control gear has, on the one hand, a spring that prestresses the door handle in one of its pivoting directions and exerts a first torque on the door handle. On the other hand, the control gear has a movement transmission means. Depending on the pivoting movement of the door, the movement transmission means exerts a second torque acting against the first torque on the door handle. Such a control gear is structurally simple and inexpensive to manufacture.

To exert the first and / or second torque, the control gear has a first and / or second tension element which engages on the door handle at a distance from the door handle axis over a first and / or second lever arm length.

In this context, it can be advantageous that the first and / or second lever arm length changes depending on a pivoting position of the door handle. When the door is opened from the closed position, an initially large lever arm length can increase the torque exerted on the door handle. In this way, drive losses, for example an extension of the tension elements of the control gear, during an initial tension load can be compensated for.

The control gear can advantageously have at least one deflection roller which defines the course of the tension elements. As a result, a course of the pull element connected to the door handle can be deflected in any way without accepting transmission losses due to friction etc. For example, the tension element can be connected to a tension spring arranged at a distance from the bearing housing. The location, position and size of the spring can be adapted to the requirements. In a particularly simple embodiment of the invention, a cam disk can be assigned to the door handle in a rotationally fixed manner. A first and second tension element, which exert the aforementioned opposite first and second torques on the door, are guided in the opposite direction via the cam disc. The radius of the cam can be adjusted according to the required lever arm length.

In an alternative embodiment, the control gear can have a loop-shaped, closed tension element which, on the one hand, wraps around the drive part and, on the other hand, around the cam disc of the door. As a result, a rotational movement of the drive part can be transmitted to the cam disk of the door in a technically simple and effective manner. The loop-shaped, closed tension element enables a particularly cost-effective and effective transmission between the drive part and the cam disc.

The functionality of the control gear mentioned above is increased if an additional tightening means is provided, which tightens the loop-shaped closed tension element. A spring inserted in the loop of the tension element can serve as a tightening means.

In order to avoid tilting of the door in the slide track during an opening and closing movement, one of the control gears is provided on each of the two narrow sides of the door opposite in the axial direction. The control gears provided on both sides of the door enable the door handle to be swiveled synchronously and smoothly.

The invention is explained below using two exemplary embodiments. Show it:

FIG. 12 shows a sectional side view corresponding to FIG. 11.

According to the first exemplary embodiment, FIG. 1 shows a cooking appliance 1 as a household appliance. The cooking device 1 has operating and display elements 2 on the front with an assigned control unit. A cooking space 3 is also provided in the cooking device 1. The cooking space 3 is delimited by a muffle 4 which is open at the front. The front opening of the muffle 4 is framed by a front muffle frame 8. The cooking space 3 can be closed by means of a door 5, which is pivotably mounted about a horizontal hinge axis 12. The door 5 has an inner door pane 7 and an outer door pane 9 made of glass or Glass ceramic on. A door handle 17 is provided on an upper end face 6 of the door 5 and is pivotably mounted in a bearing housing 21.

In FIG. 2, the arrangement consisting of the door handle 17 and the bearing housing 21 is shown enlarged in sections in a perspective view. For simplification, the inner and outer door panes 7, 9 of the door are omitted. The door handle 17 has a handle strip 13, which is connected to a pivoting part 16 via bearing blocks 15. The pivoting part 16 forms the upper end face 6 of the door 5 and has pivots 19 on both sides in the longitudinal direction. These are rotatably supported in the bearing housing 21. Both the bearing housing 21 and the swivel part 16 are preferably made as an injection molded part from a thermosetting plastic. Stiffening elements 23 are formed on both long sides of the bearing housing 21. These plunge into a door interior 41 and are detachably fastened, for example screwed, to the side edge strips 25 of the door 5.

Additional stiffening elements 27 are formed on the front side of the bearing housing 21. 3, the stiffening elements 27 are in contact with the outer door pane 9. FIG. 3 shows a sectional view along the line A-A from FIG. 2, in which the door panes 7, 9 are indicated by dashed lines. Accordingly, the stiffening element 27 is in contact with the outer door pane 9, while the inner door pane 7 lies on a contact surface 22 of the bearing housing 21 with the interposition of a seal 29. 3 further shows that the bearing housing 21 has a support surface 31. The support surface 31 is arranged between the lateral pivot pins 19 and extends in the axial direction of the swivel part 16 over almost the entire length of the swivel part 1. In contact with the support surface 31 there is a corresponding counter surface 33 of the swivel part 16. The swivel movement of the door handle 17 is thus whose pivot part 16 is supported on the support surface 31. Two stops 35, 37 are also formed on the bearing housing 21, which limit a pivoting range of the door handle 17.

As shown in Figure 2, the door handle 17 is assigned a tension spring 39 which biases the door handle 17 in a pivoting direction. The tension spring 39 is provided below the bearing housing 21 and extends in the longitudinal direction of the bearing housing 21. The tension spring 39 is freely suspended in the door interior 41 formed between the door panes 7, 9. Due to the freely suspended arrangement of the tension spring 39 within of the door interior 41 is a free expansion and thus a low-wear loading of the tension spring 39 is achieved.

The two ends of the tension spring 39 are each connected to the swivel part 16 via a first tension cable 43 in order to transmit a tension spring force to the swivel part 16. The first traction cables 43 are guided to cam plates 47 via deflection rollers 45, which are rotatably mounted on the stiffening elements 27. The cams 47 are connected on both sides in a rotationally fixed manner to the longitudinal ends of the swivel part 16. Each of the first traction ropes 43 is fixed to an attachment point 46 on the circumference of the cam plate 47. As a result, the tension spring 39 pretensions the door handle 17 against the first stop 35 and exerts a first torque M1 in a pivoting direction on the door handle 17 (FIG. 4). To protect against contamination, the cams 47 are arranged within lateral recesses of the swivel part 16. The cutouts are covered on the end face by cover sections 18 of the swivel part 16.

A second traction cable 48 engages on the circumference of each of the cams 47. The second traction cable 48 is guided opposite the first traction cable 43 around the cam plate 47 and fixed at the attachment point 46 on the circumference of the cam plate 47. The first and second pull cables 43, 48 and the cam disks 47 form components of a control gear 38. The control gear 38 transmits a pivoting movement of the door 5 to the door handle 17, i.e. when the door 5 is pivoted in a first pivoting direction, the control gear 38 pivots the door handle 17 in a second pivoting direction opposite to the first pivoting direction. The structure and the mode of operation of the control gear 38 are explained below with reference to FIG. 4.

FIG. 4 shows an upper and lower section of the door 5 in a sectional view along the line BB from FIG. 1. The door 5 is arranged in a closed position. In the lower portion of the door 5, a drive drum 54 is arranged, which serves as a drive part of the control gear. Starting from the drive drum 54, a rotary movement is transmitted to the cam plate 47 via the pull cable 48. The pull cable 48 engages on the circumference of the cam plate 47. The traction cable 48 thus converts the rotary movement of the drive drum 54 into a rotary movement of the cam plate 47. If the door 5 is pivoted downward from its closed position shown in FIG. 4, the drive drum 54 rotates. The initiation of movement in the drive drum 54 is described later with reference to the second exemplary embodiment. The rotary movement of the drive drum 54 is transmitted to the cam plate 47 via the pull cable 48, as a result of which a second torque M2 directed against the first torque M1 is exerted on the door handle 17. It can thereby be achieved that the horizontal orientation of the door handle 17 shown in FIG. 4 is maintained essentially independently of the pivoting position of the door 5.

If an operator exerts an upward actuating force F - for example during transport of the cooking appliance - on the door handle 17 shown in FIG. 4, the resulting pivoting movement of the pivoting part 16 of the door handle is absorbed by the tension spring 39 in a clockwise direction. This prevents the clockwise pivoting movement from being transmitted from the door handle 17 to the control gear 38. The tension spring 39 thus acts as a protective device that prevents damage to the control gear 38.

For dimensioning the spring force of the tension spring 39 or the torque M1 exerted thereby, a minimum value for the spring force of the tension spring 39 is assumed. This minimum value corresponds approximately to the frictional forces that have to be overcome to reset the door handle 17 after no actuation force F is exerted on the door handle 17. The tension spring 39 is dimensioned such that the above-mentioned minimum value is approximately 10-20% of the spring force of the tension spring 39. The spring force of the tension spring 39 is thus approximately five to ten times greater than this minimum value. If the door handle 17 is actuated incorrectly, for example by exerting the upward actuating force F (see FIG. 4), damage to the control gear 38 is prevented. At the same time, the comparatively large spring force during normal opening or closing actuation of the door handle 17 by the operator allows an ergonomically favorable operating feeling.

In order to ensure that the rotary movement of the drive drum 54 is transmitted to the door handle 17 in a correct transmission ratio, the radius of the cam plate 47 is of great importance. The radius of the cam plate 47 determines the length of the lever arm and thus the size of the torque with which the Attack pull cables 43, 48 on cam 47. On the other hand, the gear ratio with which a drive movement of the control gear 38 is converted into a pivoting movement of the door handle 17 is determined by the cam disc radius. In FIG. 5, the lever arm lengths r1, r2 of the cam plate 47 assigned to the first and second traction cables 43, 48 are of different sizes. FIG. 5 illustrates an enlarged illustration of the cam plate 47 from FIG. 4.

In Figure 5, the points of attack of the pull cables 43 and 48 are illustrated with the reference numerals A1 and A2. The point of application A1 of the pull cable 43 moves counterclockwise during an opening process of the door 5 by a rotation angle section of approximately 90 ° along the circumference of the cam plate 47. In this rotation angle section the lever arm length r1 is essentially constant. The torque M1 exerted on the door handle 17 is therefore constant during the pivoting movement of the door 5. At the same time, the point of application A2 of the pull cable 48 moves by a rotation angle section of approximately 90 ° in a counterclockwise direction along the circumference of the cam disk 47. In this rotation angle section, the lever arm length r2 decreases when the door 5 swivels out of its closed position; i.e. that the torque M2 exerted on the door handle 17 is lowest in the horizontal door position. In the horizontal door position, the torque M2 counteracts a weight of the door 5; the weight of the door 5 keeps the door 5 stable in its horizontal position. The reduced torque M2 in the horizontal door position is therefore not able to compensate for the weight of the door. The stable position of the door in its horizontal position is therefore not affected by the torque M2.

By means of an eccentric cam 47, the transmission ratio of the control gear 38 can be changed depending on the pivoting position of the door 5. Drive losses of the control gear 38, which occur, for example, at the start of a pivoting movement of the door due to an expansion of the pull cables 43, 48 or due to play in the control gear 38, can thus be compensated for.

FIG. 6 shows a cooking device according to a second exemplary embodiment. The cooking appliance has a useful space module 83, indicated by a dash-dotted line, in which the cooking appliance muffle 3, not shown, is arranged. Below the useful space module 83 a storage space module 79 is arranged. The storage space module 79 has a storage space 61, in which a guide system 58 is provided for the door 5. With the guide system 58, the cooking appliance door 5 shown in broken lines can be moved into the storage space module 79. According to FIG. 6, the storage space module 79 serves as a base or foundation on which the useful space module 83 is mounted. The storage space module 79 is designed as an upwardly open sheet metal housing. Step-shaped contact shoulders 85 are formed on the upper edge of the side walls 80 of the sheet metal housing 79. As indicated in FIG. 6, the useful space module 83 lies on the contact shoulders 85. The operating and display elements 2 shown in FIG. 1 and an associated control unit are provided in the useful space module 83. The operating and display elements 2 together with the assigned control unit are functional independently of the storage space module 79.

The control gear 38 of the second exemplary embodiment has, as the drive part, a rotary shaft 57 on which the drive drum 54 already mentioned in the first exemplary embodiment is formed. The rotary shaft 57 is operatively connected to a guide element 59 of the guide system 58.

The structure and mode of operation of the guide system 58 for the door 5 and the generation of a drive movement for the control gear 38 are explained below:

As shown in FIG. 6, the guide element 59 is part of the guide system 58, with the aid of which the door 5 is pushed into the storage space 61 provided below the cooking space 3 during an opening process. It can be seen from FIGS. 6 and 7 that the guide system 58 has slide tracks 63. The slide tracks 63 are formed in the two opposite side walls 80 of the storage space module 79. The opposite slide tracks 63 guide sliders 60 of the guide element 59. The sliders 60 are welded to one another via a connecting rod 62. The guide element 59 is therefore guided like a guide carriage in the opposite slide tracks 63. Adjusting levers 67 are welded to the connecting rod 62 between the two sliding pieces 60. As shown in the enlarged perspective section of FIG. 8, the actuating levers 67 are positively connected to the rotary shaft 57 of the control gear 38. The rotary shaft 57 is indicated in FIGS. 6 and 7 in a dash-dotted line. The above-mentioned positive connection between the adjusting levers 67 of the guide carriage 59 and the rotary shaft 57 of the door 5 is shown in FIG. In Figure 8, the inner and outer door panes 7, 9 of the door 5 are omitted. Accordingly, the rotary shaft 57 is rotatably supported in the opposite edge strips 25 of the door 5. For a positive connection, the adjusting levers 67 of the guide carriage 59 each have a rectangular recess 69 (FIG. 8). A corresponding rectangular shaped section 71 of the rotary shaft 57 is held in the recess 69. The lateral edge strips 25 of the door 5 are each provided with a U-shaped groove on the outside, which serves as a guide rail. In these guide rails 25, a bearing roller 65 is slidably guided on both sides. The bearing rollers 65 are attached to the side wall 80 of the storage space module 79. The U-shaped groove serving as a guide rail is formed with an open end 26 on its lower end face. When the door is removed later, the bearing roller 65 fixed to the housing can be released from the associated guide rail 25 by the open end 26.

Each of the opposite slide tracks 63 has a starting section 90 and an insertion section 91. According to FIGS. 9a to 9c, a slope angle of the starting section 90 is approximately 45 °. The starting section 90 also takes up about 30% of the total length of the slide track 63, while the transition between the starting section 90 and the insertion section 91 is arcuate. The insertion section 91 runs essentially in a horizontal plane. The bearing rollers 65 fixed to the housing are arranged approximately at the level of the insertion section 91 of the sliding track 63.

The course of movement of the guide carriage 59 of the door 5 in the link tracks 63 is described with reference to FIGS. 9a to 9c. The door 5 is shown in its closed position in FIG. 9a. In the closed position, the sliders 60 of the guide carriage 59 are located in the start section 90 of the sliding track 63. When the door 5 opens from its closed position shown in FIG. 9a, the sliders 60 of the guide carriage 59 initially move upward. The actuating lever 67 of the guide carriage 59 thereby lift the door 5 upwards. With this lifting movement of the door 5, a lower end face 93 of the door 5 pivoting into the storage space 61 is simultaneously displaced upward away from a floor 117 of the storage space module 79, as can be seen from FIG. 9b. A pivoting range S of this lower end face 93 projecting into the storage space 61 and indicated by a dash-dotted line is thereby reduced. After the guide carriage 59 is moved from the start section 90 into the horizontal insertion section 91 (FIG. 9c), the door 5 is in a horizontal plane in which it can be inserted into the storage space 61. During the pivoting movement of the door 5, a pivoting angle changes between the door 5 and the guide slide 59. Since the rotary shaft 57 of the control gear 38 is positively held in the actuating levers 67 of the guide slide 59, the change in the pivoting angle between the door 5 and the guide slide 59 causes a rotation of the rotary shaft 57. That is, the rotary shaft 57 is forcibly rotated by the guide element 59 when the door 5 is pivoted.

FIG. 10 explains how the control gear 38 transmits the forced rotation of the rotary shaft 57 to the door handle 17. FIG. 10 shows a side sectional view of the upper and lower section of the door 5 according to the second exemplary embodiment. It can be seen from this that the actuating lever 67 projects into the door interior 41 through an access opening 129 of the door 5 and is positively connected to the rotary shaft 57. As can be seen in FIG. 8 and FIG. 10, the drive drum 54 is formed on the rotary shaft 57 and is arranged on the rotary shaft 57 in a rotationally fixed manner. The drive drum 54 is circumferentially engaged with the pull cable 48. As in the first exemplary embodiment, the pull cable 48 is connected to the door handle 17.

During the pivoting movement of the door 5 there is therefore a pivoting movement between the guide carriage 59 and the door 5, as a result of which the rotary shaft 57 is forcibly rotated. The rotary movement of the rotary shaft 57 is transmitted to the traction cable 48 via the drive drum 54. The pull cable 48 converts the rotary movement of the rotary shaft 57 into a rotary movement of the cam plate 47 and exerts the second torque M2 on the door handle 17, which is directed against the first torque M1. The door handle 17 thus maintains its horizontal orientation regardless of the pivoting position of the door 5.

In contrast to FIG. 4 of the first exemplary embodiment, in FIG. 10 the first pull cables 43 acting on both sides of the cams 47 of the pivoting part 16 of the door handle 17 are not connected to a common tension spring. Rather, according to FIG. 10, a separate tension spring 39 is assigned to each of the first tension cables 43. The tension spring 39 is fastened with a spring end to the edge strip 25 of the door 5. The other spring end of the tension spring 39 is coupled to the tension cable 43 via a retaining eye 75, whereby the first torque M1 is exerted on the door handle 17 in a counterclockwise direction.

The control gear 38 shown in FIG. 10 has a third traction cable 77. The third traction cable 77 is guided on the one hand in circumferential engagement with the drive drum 54 of the rotary shaft 57 and in the opposite direction to the second traction cable 48 around the drive drum 54. On the other hand, the third traction cable 77 is in connection with the retaining eye 75 of the first traction cable 43. The first, second and third traction cables 43, 48, 77 of the control gear 38 form a closed cable pull, which for transmitting the rotary movement to the door handle 17, the cam plate 47 and the drive drum 54 envelops.

To tighten the closed cable 43, 48, 77, a tensioning spring 79 is integrated in the third cable 77. The tensioning spring 79 serves to tighten the closed cable 43, 48, 77. In addition, the tensioning spring 79 increases the torque M1, which is exerted by the tension spring 39 on the door handle 17. Both the tensioning spring 79 and the tension spring 39 are therefore present for exerting the torque M1. Two comparatively small-sized springs can thus advantageously be used, which consume only little space in the limited interior 41 of the door.

If the operator, for example during transport of the cooking device 1, exerts an upward actuating force F on the door handle 17 shown in FIG. 4, the resulting pivoting movement of the pivoting part 16 of the door handle becomes clockwise from the tension spring 39 and from the tensioning spring 79 added. The resulting pivoting movement of the pivoting part 16 is therefore not transmitted from the door handle 17 to the control gear 38. This prevents damage to the control gear 38.

The dimensioning of the spring force of the tension springs 39, 79 depends on the minimum value for the spring force given in connection with FIG. 4.

Furthermore, the pull cables 43, 48, 77 can be provided with setting elements for setting a tension. By means of the setting elements, they can be attached to the The same tension is applied to the pull cables provided on the door side. As a result, synchronous operation of the two control gears 38 is achieved.

A weight compensation arrangement 94 for the door 5 of the second exemplary embodiment is described below with reference to FIGS. 7, 11 and 12. The weight balancing arrangement 94 exerts a balancing force acting against the weight of the door 5 on the door 5 during a movement of the door 5. The weight of the door 5 is therefore not picked up by the operator during a door movement, but by the weight compensation arrangement 94.

FIG. 7 shows the storage space module 79 in a perspective view, one of which. Room divider 111 described later is shown separately. The weight compensation arrangement 94 has a pivot lever 95 on each of the opposite side walls 80. The pivot lever 95 is pivotally mounted on the opposite side walls 80 via a lever axis 97. FIG. 11 shows one of the side walls 80 in an enlarged side sectional view along the line D-D from FIG. 7. Accordingly, the pivot lever 95 projects into the start section 91 of the slide track 63 and is in engagement with the slide 60 of the guide carriage 59. A swivel range of the swivel lever 95 is designed such that the swivel lever 95 only engages with the slide 60 of the guide carriage 59 in the region of the starting section 90. In contrast, the pivot lever 95 is in the horizontal section 91 out of engagement with the slide 60 of the guide carriage 59. The pivot lever 95 is connected to a tension spring 103. The tension spring 103 is attached to the side wall 80. In Figure 11, the tension spring 103 biases the pivot lever 95 counterclockwise.

When the door 5 shown in dashed lines in FIG. 11 is pivoted downward from its closed position into the horizontal position, the slide piece 60 extends from the start section 90 into the horizontal section 91 of the sliding track 63. During this movement, the slide piece 60 of the guide slide 59 presses against the spring-loaded pivot lever 95. The pivot lever 95 thus exerts a balancing force on the slider 60. The compensating force acts counter to the weight of the door 5.

As shown in FIG. 11, the pivot lever 95 is pressed by means of the spring 103 against a first end stop 99, which is formed by a rubber pad. In the in In the position shown in FIG. 11, the pivot lever 95 allows the slide 60 of the guide carriage 59 to start moving from the closed position of the door 5. During this initial movement, the swivel lever 95 is disengaged from the swivel lever 95. According to FIG. 11, the sliding piece 60 only comes into contact with the swivel lever 95 at a swivel angle of the door 5 of approximately 20 °. This simplifies the initial movement of the door for the operator 5 from their closed position. Furthermore, the pivoted lever 95 preloaded according to FIG. 11 acts like a stop against which the slide 60 of the guide carriage 59 abuts when the door 5 opens. A certain pivoting position of the door 5 is thus signaled to the operator. In the present case, this pivot position corresponds to a removal position described later, in which a simple removal of the door 5 from the guide system 58 is made possible.

Furthermore, the weight compensation arrangement 94 has a pivotably mounted holding element 105 which is prestressed by means of a spring 106. The spring-biased holding element 105 presses the slide 60 of the guide carriage 59 in the direction of the pivot lever 95 during the above-described initial movement of the door 5. As a result, the door 5 is held stably in the removal position shown in FIG.

In FIG. 12, the door 5 is mounted horizontally and shown pushed into the storage space 61. The slide piece 60 of the guide carriage 59 of the door 5 is located in the horizontal insertion section 91 of the slide track 63. When the slide piece 60 moves in the area of the insertion section 91 of the slide track 63, the pivot lever 95 is out of engagement with the slide piece 60. The pivot lever 95 therefore does not exercise any Balancing force on the door 5. While the slider 60 runs in the insertion section 91 of the slide track 63, the pivot lever 95 is by means of the spring 103 clockwise against a second end stop 101, which is also formed by a rubber pad.

The pivot lever 95 has a driver 107. The driver 107 of the swivel lever 95 projects into the slide track 63 in FIG. 12. According to FIG. 12, the slide piece 60 has been moved from the start section 90 into the insertion section 91 of the slide track 63. The actuating lever 95 is biased against the second end stop 101 and is in a stationary position. When the door 5 is moved out of the storage space 61, the slider 60 comes into engagement with the driver 107 of the swivel lever 95. As a result, the swivel lever 95 moves out of its stationary position brought and comes again into a pressure system with the slider 60 of the guide carriage 59. As a result, the pivot lever 95 can exert the compensating force on the guide carriage 59 again during a pivoting movement of the door 5.

The detachable mounting of the door 5 on the guide system 58 is explained below with reference to FIG. 8. Due to the detachable mounting of the door 5 in the guide system 58, the door 5 can be easily removed for cleaning: As already described with reference to FIG. 8, the adjusting levers 67 have a rectangular recess 69. The corresponding rectangular shaped section 71 of the rotary shaft 57 is held in the rectangular recess 69. This creates a positive connection between the guide carriage 59 and the rotary shaft 57. A locking element 73 is explained below, which is mounted on the rotary shaft 57 according to FIG. The locking element 73 is displaceable between a locking position and a release position. In the release position, the locking element 73 releases the mounting of the rotary shaft 57 in the actuating lever 67. In a locking position of the locking element 73, the rotary shaft 57 is permanently connected to the actuating lever 67.

The room divider 111 mentioned in connection with FIG. 7 is explained below. As can be seen in particular from FIG. 6, the room divider 111 is arranged in the storage space module 79. The room divider 111 divides the storage space 61 into a first storage space 61a and a second storage space 61b. The room divider 111 has a horizontal intermediate floor 113 and side walls 115. The door 5 can be moved into the first storage space 61a. The room divider 111 also separates the guide system 58 formed from the sliding track 62 and the guide carriage 59 and the weight compensation arrangement 94 from the second storage space 61b. Baking trays or other accessories can be stored in the second storage space 61b.

As can be seen from FIGS. 9a to 9c, the room divider 111 is arranged below the start section 90 and the insertion section 91 of the sliding track 63. The intermediate floor 113, together with the side walls 115 and a housing base 117, form an access opening 119. This is arranged at a distance from the swivel area S of the lower end face 93 of the door 5, indicated by a dash-dotted line. In the area of the access opening 119 of the second storage space 61b Display elements 121 provided (Figures 7 and 8). The display elements 121 are designed as cams which are fastened to the bottom 117 of the storage space 61. The display elements 121 show the operator a maximum permissible length for objects that can be stored in the second storage space 61b without protruding into the pivoting area S of the lower end face 93 of the door 5. On the side walls 115 of the room divider 111, front panels 123 are formed (FIG. 7). The screens 123 serve as a screen for the first storage space 61a. In addition, a collecting channel 125 is provided in the housing base 117 in the area of the front access opening 119 in order to keep the second storage space 61b free of impurities, for example dripping condensate water.
