From the DE 199 06 913 is a generic household appliance with a door known that closes a utility room in the home appliance. Below the working space an opening with a guide system arranged therein is formed in a horizontal plane. The door can be inserted into the opening via the guide system.

document EP 0659960 discloses a home appliance with a hinged door handle.

The object of the present invention is to provide a household appliance or a household appliance door, which is to operate in an ergonomically favorable manner.

The object of the present invention is achieved by a household appliance with the features of claim 1. According to the characterizing part of claim 1, the door handle is associated with at least one control gear, which pivots the door handle in a direction opposite to the first pivoting direction of the second pivoting direction upon pivoting of the door in a first pivoting direction. Thereby, a spatial orientation of the door handle can be maintained substantially independent of a pivotal position of the door. The door handle is thus always aligned independently of a door pivoting position in the direction of an operator. When the door is open, it is therefore no longer necessary to embrace the door edge to get to 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. Thus, a movement of the guide element in the slide track can 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, which rolls when displaced in the slide track and transmits a rotational movement to the control gear.

Instead of the above-mentioned rotational movement, according to a further embodiment of the invention, the guide element can be pivotally mounted relative to the door. During a movement in the slide track therefore takes place a pivoting movement between the guide member 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 may have a drive part which transmits a movement, for example a pivoting movement or a rotational movement, to the control gear.

To transmit a serving as a drive movement pivoting movement on the control gear, the guide element on a lever. The lever is connected to the drive part of the control gear in a positive connection. As a result, the guide element is pivotally connected to the control gear in the manner of a hinge.

Advantageously, the control gear can be assigned an adjustable locking element which is adjustable between a locking position and a release position. 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 in a simple manner can be removed from the household appliance.

In order to achieve an ergonomically favorable for the operator opening or closing movement of the door, the door is pivotally mounted in addition to the storage in the slide tracks to a housing-fixed hinge axis. Since the hinge axis is executed fixed to the housing, a resulting design effort - compared to a moving hinge axis - low.

According to a particularly advantageous embodiment, the slide track on an insertion portion, in which the door is guided in a substantially horizontal plane is. By means of the insertion section, a horizontal movement of the door can be achieved. A guide of the door in the storage space or from the storage space is therefore possible for the operator in a simple and ergonomically favorable manner.

In order to achieve an ergonomic particularly advantageous horizontal movement of the door for the operator, the housing-fixed hinge axis is arranged substantially at the height of the insertion portion of the slide track.

In a particularly advantageous embodiment of the control gear, the control gear on the one hand on a spring which biases 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 motion transmission means. The motion transmission means exerts - in response to the pivotal movement of the door - acting against the first torque second torque on the door handle. Such a control gear is structurally simple and inexpensive to produce.

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

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

Advantageously, the control gear can have at least one deflection roller which defines the course of the tension elements. As a result, a profile of the tension member connected to the door handle can be deflected in any desired manner without accepting transmission losses due to friction, etc. For example, the tension element may be connected to a tension spring remote from the bearing housing. In this case, location, location and size of the spring can be adjusted according to the requirements.

In a particularly simple embodiment of the invention, the door handle can be associated with a cam rotatably. About the cam in the opposite direction, a first and second tension element are performed, which exert the above-mentioned opposite first and second torques on the door. The radius of the cam can be adjusted according to the required Hebelarmlänge.

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

The operability of the above-mentioned control gear is increased when an additional tightening means is provided, which tightens the loop-shaped closed tension element. As a tightening agent used in the loop of the tension element spring can serve.

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 at each of the two narrow sides of the door opposite in the axial direction. The two-sided control gear provided on the door allow a synchronous and smooth pivoting of the door handle.

In the FIG. 1 is a cooking appliance 1 shown according to the first embodiment as a household appliance. The cooking appliance 1 has front-side operating and display elements 2 with an associated control unit. In the cooking appliance 1, a cooking chamber 3 is also provided. The cooking chamber 3 is bounded by a muffle 4 open at the front. The front opening of the muffle 4 is framed by a front muffle frame 8. The cooking chamber 3 can be closed by means of a door 5, which is mounted pivotably about a horizontal articulation axis 12. The door 5 has an inner door pane 7 and an outer door pane 9 made of glass or Glass ceramic on. At an upper end face 6 of the door 5, a door handle 17 is provided which is pivotally mounted in a bearing housing 21.

In the 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 simplicity, the inner and outer door panels 7, 9 of the door are omitted. The door handle 17 has a handle bar 13 which is connected via bearing blocks 15 with a pivoting part 16. The pivoting part 16 forms the upper end face 6 of the door 5 and has pivot pins 19 on both sides in the longitudinal direction. These are rotatably mounted in the bearing housing 21. Both the bearing housing 21 and the pivot member 16 are preferably made as an injection molded part of a thermoset plastic. At both longitudinal sides of the bearing housing 21 stiffening elements 23 are formed. These dive into a door interior 41 and are releasably attached to lateral edge strips 25 of the door 5, for example screwed.

On the bearing housing 21 additional stiffening elements 27 are formed fronseitig. The stiffening elements 27 are according to the FIG. 3 in contact with the outer door window 9. The FIG. 3 shows a sectional view taken along the line AA from the FIG. 2 in which the door windows 7, 9 are indicated in dashed lines. Accordingly, the stiffening element 27 is in contact with the outer door pane 9, while the inner door pane 7 lies with the interposition of a seal 29 on a contact surface 22 of the bearing housing 21. From the FIG. 3 further shows that the bearing housing 21 has a support surface 31. The support surface 31 is disposed between the lateral pivot pins 19 and extends in the axial direction of the pivot member 16 over almost the entire length of the pivot member 1. In contact with the support surface 31 is a corresponding counter surface 33 of the pivot member 16. In the pivotal movement of the door handle 17 is thus the pivot member 16 is supported on the support surface 31. On the bearing housing 21 further two stops 35, 37 are formed, which limit a pivoting range of the door handle 17.

Like in the FIG. 2 is shown, the door handle 17 is associated with 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 extends. The tension spring 39 is arranged freely suspended in the door interior 41 formed between the door panes 7, 9. Due to the free-hanging arrangement of the tension spring 39 within of the door interior 41 is a free expansion and thus a low-wear load of the tension spring 39 is reached.

The two ends of the tension spring 39 are each connected via a first pull cable 43 with the pivot member 16 to transmit a tension spring force on the pivot member 16. The first traction cables 43 are guided via pulleys 45, which are rotatably mounted on the stiffening elements 27, to cams 47. The cams 47 are rotatably connected on both sides with the longitudinal ends of the pivot member 16. Each of the first traction cables 43 is fixed to an attachment point 46 on the circumference of the cam 47. As a result, the tension spring 39 biases 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. FIG. 4 ). To protect against contamination, the cams 47 are arranged within lateral recesses of the pivoting part 16. The recesses are frontally covered by cover portions 18 of the pivot member 16.

At the periphery of each of the cams 47, a second pull cable 48 engages. The second pull cable 48 is guided opposite to the first pull cable 43 around the cam plate 47 and fixed to the attachment point 46 on the circumference of the cam plate 47. The first and second traction 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, ie when the door 5 is pivoted in a first pivoting direction, the control gear 38 pivots the door handle 17 in a direction opposite to the first pivoting direction of the second pivoting direction. The structure and operation of the control gear 38 are described below with reference to FIG. 4 explained.

In the FIG. 4 is an upper and lower section of the door 5 in a sectional view taken along the line BB of the FIG. 1 shown. 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 driving part of the control gear. Starting from the drive drum 54, a rotational movement is transmitted via the pull cable 48 to the cam plate 47. The pull cable 48 engages the circumference of the cam 47. Thus, the pull cable 48 converts the rotational movement of the drive drum 54 into a rotational movement of the cam plate 47.

Will the door 5 from her in the FIG. 4 The drive drum 54 rotates downward as shown in the closed position shown. The introduction of movement into the drive drum 54 will be described later on the basis of the second exemplary embodiment. The rotational movement of the drive drum 54 is transmitted via the pull cable 48 to the cam 47, whereby a counter to the first torque M1 directed second torque M2 is exerted on the door handle 17. This can be achieved that in the FIG. 4 shown horizontal orientation of the door handle 17 is maintained substantially independent of the pivotal position of the door 5.

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

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

To ensure that the rotational movement of the drive drum 54 is transmitted in a correct gear ratio to the door handle 17, the radius of the cam 47 is of great importance. The radius of the cam 47 determines on the one hand the length of the lever arm and thus the size of the torque with which the Pull ropes 43, 48 attack on the cam 47. On the other hand, the gear ratio is determined by the cam radius, with which a drive movement of the control gear 38 is converted into a pivoting movement of the door handle 17. In the FIG. 5 the lever arm lengths r1, r2 of the cam disk 47 assigned to the first and the second pull cable 43, 48 are of different sizes. The FIG. 5 illustrates an enlarged view of the cam 47 of the FIG. 4 ,

In the FIG. 5 is the points of application of the traction cables 43 and 48 with the reference numerals A1 and A2 illustrated. The point A1 of the pull cable 43 moves counterclockwise during an opening operation of the door 5 by a rotation angle section of about 90 ° along the circumference of the cam 47. In this rotation angle section, the lever arm length r1 is substantially constant. The force exerted on the door handle 17 torque M1 is therefore constant during the pivotal movement of the door 5. At the same time, the engagement point A2 of the traction cable 48 moves counterclockwise about the rotational angle section of about 90 ° along the circumference of the cam plate 47. In this rotational angle section, the lever arm length r2 decreases from its closed position upon pivotal movement of the door 5; that is, in the horizontal door position, the torque M2 applied to the door handle 17 is lowest. In the horizontal door position, the torque M2 counteracts a weight force of the door 5; the weight of the door 5 keeps the door 5 stable in its horizontal position. The reduced in the horizontal door position torque M2 is therefore not able to compensate for the weight of the door. The stable position of the door in its horizontal position is thus not affected by the torque M2.

By an eccentrically shaped cam 47, the transmission ratio of the control gear 38 can be changed in dependence on the pivotal position of the door 5. Drive losses of the control gear 38, which arise, for example, at the beginning of a pivotal movement of the door by expanding the traction cables 43, 48 or by a game in the control gear 38, can thus be compensated.

In the FIG. 6 a cooking appliance according to a second embodiment is shown. The cooking appliance has a utility space module 83 indicated by a dot-dash line, in which the cooking appliance muffle 3 (not shown) is arranged. Below the utility room module 83 a storage module 79 is arranged. The storage 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 dashed lines is displaceable in the storage module 79. The storage module 79 serves according to the FIG. 6 as a pedestal or foundation on which the utility module 83 is supported. The storage module 79 is formed as an upwardly open sheet metal housing. At the upper edge of the side walls 80 of the sheet metal housing 79 step-shaped abutment shoulders 85 are formed. On the abutment shoulders 85 is as in the FIG. 6 indicated in the correct position, the Nutzraummodul 83. In the Nutzraummodul 83 are in the FIG. 1 shown control and display elements 2 and an associated control unit provided. The control and display elements 2, together with the associated control unit independent of the storage module 79 are functional.

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

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

Like in the FIG. 6 is shown, the guide member 59 is part of the guide system 58, by means of which the door 5 is inserted during an opening operation in the space provided below the cooking chamber 3 61. From the FIGS. 6 and 7 shows 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 module 79. The opposite slide tracks 63 guide sliders 60 of the guide member 59. The sliders 60 are welded together via a connecting rod 62. The guide element 59 is therefore guided like a guide slide in the opposite slide tracks 63. Between the two sliders 60 adjusting lever 67 are welded to the connecting rod 62. As in the enlarged perspective view of the FIG. 8 is shown, the adjusting lever 67 with the rotary shaft 57 of the control gear 38 are positively connected. The rotary shaft 57 is in the FIGS. 6 and 7 indicated in dotted line.

The above-mentioned positive connection between the control levers 67 of the guide carriage 59 and the rotary shaft 57 of the door 5 is in the FIG. 8 shown. In the FIG. 8 are the inner and outer door panel 7, 9 of the door 5 omitted. Accordingly, the rotary shaft 57 is rotatably mounted in the opposite edge strips 25 of the door 5. For positive connection, the adjusting lever 67 of the guide carriage 59 each have a rectangular recess 69 ( FIG. 8 ). In the recess 69, a corresponding rectangular shape portion 71 of the rotary shaft 57 is supported. The lateral edge strips 25 of the door 5 are provided to the outside each with a U-shaped groove which serves as a guide rail. In these guide rails 25 are each a bearing roller 65 slidably guided on both sides. The bearing rollers 65 are fixed to the side wall 80 of the storage module 79. The serving as a guide rail U-shaped groove is formed at its lower end side with an open end 26. Through the open end 26, the housing-fixed bearing roller 65 can be released from the associated guide rail 25 at a later-described door removal.

Each of the opposing slide tracks 63 has a start portion 90 and an insertion portion 91. According to the FIGS. 9a to 9c is a pitch angle of the starting portion 90 in about 45 °. The start portion 90 also occupies about 30% of the total length of the slide track 63, while the transition between the start portion 90 and the insertion portion 91 is arcuate. The insertion portion 91 extends substantially in a horizontal plane. The housing-fixed bearing rollers 65 are arranged approximately at the height of the insertion portion 91 of the slide track 63.

Based on FIGS. 9a to 9c the course of movement of the guide carriage 59 of the door 5 in the slide tracks 63 will be described. In the FIG. 9a the door 5 is shown in its closed position. In the closed position, the sliders 60 of the guide carriage 59 are in the starting portion 90 of the slide track 63. At an opening movement of the door 5 from their in the FIG. 9a shown closed position, the sliders 60 of the guide carriage 59 first move upward. The adjusting lever 67 of the guide carriage 59 thereby lift the door 5 upwards. With this lifting movement of the door 5, at the same time, a lower end face 93 of the door 5, which pivots into the storage space 61, moves away from a floor 117 of the storage space module 79, as can be seen from FIG FIG. 9b evident. A projecting into the storage space 61, indicated by dash-dotted line swivel range S of this lower end face 93 is thereby reduced. After the guide carriage 59 is moved from the starting portion 90 into the horizontal insertion portion 91 ( FIG. 9c ), the door 5 is in a horizontal plane in which it can be inserted into the storage space 61. During the pivotal movement of the door 5, a pivoting angle between the door 5 and the guide carriage 59 changes. Since the rotary shaft 57 of the control gear 38 is positively held in the adjusting levers 67 of the guide carriage 59, the change of the swivel angle between the door 5 and the guide carriage 59 causes a rotation of the rotary shaft 57. That is, the rotary shaft 57 is forcibly rotated during the pivotal movement of the door 5 by the guide member 59.

Based on FIG. 10 is explained in which way the control gear 38 transmits the forced rotation of the rotary shaft 57 on the door handle 17. In the FIG. 10 Fig. 3 is a side sectional view of the upper and lower portions of the door 5 according to the second embodiment. It follows that the adjusting lever 67 projects through an access opening 129 of the door 5 in the door interior 41 and is positively connected to the rotary shaft 57. Again FIG. 8 and the FIG. 10 can be seen, the drive drum 54 is formed on the rotary shaft 57, which is rotatably mounted on the rotary cell 57. The drive drum 54 is circumferentially with the pull cable 48 into engagement. The pull cable 48 is, as in the first embodiment, with the door handle 17 in connection.

During the pivoting movement of the door 5 therefore results in a pivoting movement between the guide carriage 59 and the door 5, whereby the rotary shaft 57 is forced rotated. The rotational movement of the rotary shaft 57 is transmitted to the pull cable 48 via the drive drum 54. The traction cable 48 converts the rotational movement of the rotary shaft 57 into a rotational movement of the cam 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 retains its horizontal orientation regardless of the pivotal position of the door 5.

In contrast to FIG. 4 of the first embodiment are in the FIG. 10 the first traction 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 the FIG. 10 each of the first traction cables 43 assigned its own tension spring 39. The tension spring 39 is fixed with a spring end on the edge bar 25 of the door 5. The other spring end of the tension spring 39 is coupled via a holding eye 75 with the pull cable 43, whereby the first torque M1 is exerted on the door handle 17 in the counterclockwise direction.

That in the FIG. 10 shown control gear 38 has a third pull cable 77. The third pull 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 pull cable 48 around the drive drum 54. On the other hand, the third pull cable 77 in conjunction with the retaining lug 75 of the first pull cable 43. The first, second and third pull cable 43, 48, 77 of the control gear 38 form a closed cable, for transmitting the rotational movement of the door handle 17, the cam 47 and the drive drum 54 wrapped.

For tightening the closed cable 43, 48, 77 a tightening spring 79 is integrated in the third pull cable 77. The tightening spring 79 is used to tighten the closed cable 43, 48, 77. In addition, the tightening spring 79 increases the torque M1, which is exerted by the tension spring 39 on the door handle 17. For exerting the torque M1, therefore, both the tightening spring 79 and the tension spring 39 are present. Advantageously, two relatively small-sized springs can thus be used, which consume little space in the limited door interior 41.

When the operator, for example, during a transport of the cooking appliance 1, the an upward actuating force F in the in the FIG. 4 shown door handle 17 exerts, the resulting pivotal movement of the pivot member 16 of the door handle is received clockwise by the tension spring 39 and the tightening spring 79. The resulting pivotal movement of the pivoting member 16 is thus not transmitted from the door handle 17 to the control gear 38. Damage to the control gear 38 is prevented.

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

Further, the traction cables 43, 48, 77 can be provided with adjusting elements for adjusting a tensile stress. By means of the adjusting elements, the two sides of the Door sides provided tension cables are subjected to a same tensile stress. As a result, a synchronous operation of the two control gear 38 is achieved.

The following is based on the FIGS. 7 . 11 and 12 a weight balance assembly 94 for the door 5 of the second embodiment described. The weight balance assembly 94 exerts during a movement of the door 5 acting against the weight of the door 5 compensating force on the door 5 from. The weight of the door 5 is therefore not absorbed by the operator during a door movement, but by the weight compensation arrangement 94.

In the FIG. 7 is shown in a perspective view of the storage compartment module 79, of which a space divider 111 described later is shown separately. The counterweight assembly 94 has a pivot lever 95 on each of the opposed side walls 80. The pivot lever 95 is pivotally mounted on the opposite side walls 80 via a lever axis 97. In the FIG. 11 is one of the side walls 80 in an enlarged side sectional view along the line DD of the FIG. 7 shown. Accordingly, the pivot lever 95 projects into the start portion 91 of the slide track 63 and is engaged with the slider 60 of the guide carriage 59. A pivoting range of the pivot lever 95 is designed such that the pivot lever 95 is only in the region of the start portion 90 with the slider 60 of the guide carriage 59 in engagement. In contrast, the pivot lever 95 in the horizontal portion 91 out of engagement with the slider 60 of the guide carriage 59. The pivot lever 95 is connected to a tension spring 103 in connection. The tension spring 103 is attached to the side wall 80. In the FIG. 11 the tension spring 103 biases the pivot lever 95 in the counterclockwise direction.

When panning in the FIG. 11 Dashed door 5 shown from its closed position down to the horizontal position, the slider 60 extends from the start portion 90 in the horizontal portion 91 of the link path 63. During this movement, the slider 60 of the guide carriage 59 presses against the spring-biased pivot lever 95. The pivot lever 95 thus exercises a balancing force on the slider 60 from. The compensating force counteracts the weight of the door. 5

Like in the FIG. 11 is shown, the pivot lever 95 is pressed by the spring 103 against a first end stop 99 which is formed by a rubber pad. In the in of the FIG. 11 shown position, the pivot lever 95 allows an initial movement of the slider 60 of the guide carriage 59 from the closed position of the door 5. During this initial movement of the pivot lever 95 is disengaged from the pivot lever 95. The slider 60 passes according to the FIG. 11 only at a pivot angle of the door 5 of about 20 ° into contact with the pivot lever 95. This simplifies the operator for the initial movement of the door 5 from its closed position. Moreover, the acts according to the FIG. 11 prestressed pivot lever 95 as a stop against which the slider 60 of the guide carriage 59 abuts during the opening movement of the door 5. The operator is thus signaled a certain pivot position of the door 5. In the present case corresponds to this pivotal position of a removal position described later, in which a simple removal of the door 5 is made possible from the guide system 58.

Furthermore, the counterweight assembly 94 has a pivotally mounted retaining element 105, which is biased by a spring 106. The spring-biased holding member 105 presses during the above-described initial movement of the door 5, the slider 60 of the guide carriage 59 in the direction of the pivot lever 95. As a result, the door 5 is stable in the in the FIG. 11 shown removal position held.

In the FIG. 12 the door 5 is mounted horizontally and inserted into the storage space 61. The slider 60 of the guide carriage 59 of the door 5 is located in the horizontal insertion portion 91 of the link path 63. During the movement of the slider 60 in the region of the insertion portion 91 of the slide track 63 of the pivot lever 95 is disengaged from the slider 60. The pivot lever 95 therefore exercises no Balancing force on the door 5. While the slider 60 extends in the insertion portion 91 of the slide track 63, the pivot lever 95 is by means of the spring 103 in a clockwise direction 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 pivot lever 95 protrudes in the FIG. 12 in the slide track 63. According to the FIG. 12 the slider 60 has been moved from the start portion 90 in the insertion portion 91 of the slide track 63. The adjusting lever 95 is biased against the second end stop 101 and is in a holding position. Upon a displacement of the door 5 from the storage space 61, the slider 60 comes into engagement with the driver 107 of the pivot lever 95. As a result, the pivot lever 95 from its arresting position brought and comes again in a printing system with the slider 60 of the guide carriage 59. This allows the pivot lever 95 during pivotal movement of the door 5 again exert the compensating force on the guide carriage 59.

Hereinafter, the releasable mounting of the door 5 on the guide system 58 based on FIG. 8 explained. Due to the detachable mounting of the door 5 in the guide system 58, the door 5 is easily removed for cleaning: As already with reference to the FIG. 8 is described, the adjusting lever 67 on a rectangular recess 69. In the rectangular recess 69, the corresponding rectangular shape portion 71 of the rotary shaft 57 is supported. As a result, a positive connection between the guide carriage 59 and the rotary shaft 57 is produced. In the following, a locking element 73 is explained, which according to the FIG. 8 is mounted on the rotary shaft 57. The locking element 73 is displaceable between a locking position and a release position. In the release position, the locking element 73 releases the holder of the rotary shaft 57 in the adjusting lever 67. In a locking position of the locking element 73, the rotary shaft 57 is permanently connected to the adjusting lever 67.

The following is the one related to the FIG. 7 mentioned space divider 111 explained. As in particular from the FIG. 6 is apparent, the space divider 111 is disposed in the storage module 79. The room divider 111 divides the storage space 61 into a first storage space 61 a and a second storage space 61 b. The room divider 111 has a horizontal intermediate floor 113 and side walls 115. In the first storage space 61 a, the door 5 can be moved. The space divider 111 also separates the guide system 58 formed from slide track 62 and guide carriage 59 and the weight compensation arrangement 94 from the second storage space 61 b. In the second storage space 61 b baking trays or other accessories can be stored.

Like from the FIGS. 9a to 9c is apparent, the space divider 111 is disposed below the start portion 90 and the insertion portion 91 of the slide track 63. In this case, the intermediate bottom 113 together with the side walls 115 and a housing bottom 117 an access opening 119. This is spaced from the indicated by dotted line pivoting range S of the lower end face 93 of the door 5 is arranged. In the area of the access opening 119 of the second storage space 61b Display elements 121 are provided ( FIGS. 7 and 8th ). The display elements 121 are formed as cams, which are fixed to the bottom 117 of the storage space 61. The display elements 121 indicate to the operator a maximum allowable length for items that can be stored in the second storage space 61b without protruding into the swinging area S of the lower end face 93 of the door 5. On the side walls 115 of the room divider 111 device front side aperture 123 are formed ( FIG. 7 ). The panels 123 serve as a screen for the first storage space 61a. In addition, a collecting channel 125 is provided in the housing bottom 117 in the area of the appliance front access opening 119 in order to keep the second storage space 61 b free of contaminants, for example dripping condensate water.
