Abstract

A household appliance door, which is mounted in a manner that enables it to pivot about a joint axis, has a door handle that can pivot about a door handle axis running parallel to the joint axis. At least one controlling mechanism is associated with the door handle. When the door executes a pivotal movement in a first pivoting direction, the controlling mechanism pivots the door handle in a second pivoting direction opposite the first pivoting direction, as such, reliable actuation of the door handle is achieved. The door handle is pivotally mounted in a bearing housing and the bearing housing extends in an axial direction along the entire door.

Description

Household appliance and appliance door

The present invention relates to a household appliance and a household appliance door which is pivotally mounted about a hinge axis, with a door handle which is pivotable about a door handle axis running parallel to the hinge axis, to which door handle at least one control gear is assigned, which is in a first when the door is pivoted Swivel direction pivots the door handle in a second swivel direction opposite to the first swivel direction.

A generic door is known from EP 0 659 960. The door is pivoted about a hinge axis and has a handle element. The handle element is pivotally mounted in the door about an axis running parallel to the hinge axis of the door. The spatial orientation of the handle element is maintained essentially regardless of the door position. A control gear is arranged between the handle element and a stationary area delimiting the door for transmitting the pivoting movement of the door to the door handle.

From GB 21 83 152 a door handle arrangement with a door handle is known which is pivotable about an axis running parallel to the hinge axis of the door. The door handle is pivotable between a first position in which the door is closed and a second position in which the door is open. The door handle assembly has a biasing means connected to the door handle to bias the door handle to the first position. The door handle assembly has a housing that is fitted into the door structure.

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

The object of the invention is achieved by a household appliance door or by a household appliance with the features of patent claim 1 or of patent claim 14. According to the characterizing part of claim 1, the door handle is pivotally mounted in a bearing housing which extends in the axial direction along the entire door. Tilting moments that are exerted on the door when the door handle is actuated therefore first transfer from the door handle to the bearing housing. The tilting moments are evenly distributed from the bearing housing to the door along the entire width of the door. This ensures a stable and therefore reliable mounting of the door handle on the door.

It is advantageous if the bearing housing is open on the front side over substantially the entire length of the door. Due to the open design of the bearing housing, a space delimited by the bearing housing does not act as a dirt trap that is difficult to clean; Contamination within this confined space can therefore be removed much more easily. Furthermore, the structure of the bearing housing is greatly simplified by the open design. This enables simple, inexpensive manufacture of the bearing housing.

It is also advantageous if the bearing housing closes a door interior to an end face of the door. The bearing housing also fulfills the function of protecting the door interior from vapors or condensate liquids, for example.

In one embodiment, a cam is attached to the pivotally mounted door handle. This is assigned to the control gear and guides a tension element, whereby movement transmission to the door handle is accomplished in a simple manner.

To protect the cam disk from contamination, it can be covered on the front. For this purpose, the door handle can have a cover section which extends above the cam disc.

In an advantageous embodiment of the invention, the bearing housing can have at least one additional support section. The support section is arranged between two bearing points of the door handle and supports the door handle during its pivoting movement. The support section is particularly preferably a support surface which extends essentially over the entire width of the door. This has the effect that actuating forces acting on the door handle do not lead to a deflection of the door handle and thus to an impairment of its pivoting movement. It is preferred if the bearing housing has at least one contact surface for contacting an inner and / or outer door pane. Such contact surfaces act as inexpensive spacers between the inner and outer door window. Additional separate spacers can therefore advantageously be dispensed with. In addition, the contact surfaces act as stiffening elements, with the help of which tilting moments can be absorbed by the door.

To seal the door interior against condensate vapors or the like, at least one seal is arranged on the bearing housing, on which the inner and / or outer door pane lies.

In a further embodiment, the bearing housing has end stops which limit a pivoting range of the door handle. Areas of the door lying outside the bearing housing therefore advantageously do not come into engagement with the pivoting door handle.

In addition, at least one deflection roller can be provided on the bearing housing. 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.

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. 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. The freely suspended arrangement of the tension spring 39 within the door interior 41 results in free expansion and thus a low-wear load on the tension spring 39. 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. A conventional door hinge 49 is arranged in the door interior 41 in the lower section of the door 5. The door hinge 49 projects with a hinge part 51 through the inside of the door facing the cooking chamber 3; the hinge part 51 is inserted in a corresponding receptacle of the cooking appliance. As is known, the door hinge 49 has a weight compensation mechanism, which is indicated by a weight compensation spring 56. The weight balancing mechanism exerts a balancing force on the hinge part 51 when the door 5 is pivoted; the balancing force counteracts the weight of the door 5. During the pivoting movement of the door 5, there is a lifting movement of one of the spring ends of the weight compensation spring 56 The stroke movement of the spring end is tapped by means of a hinge plunger 55 guided in a long groove 53. The hinge plunger 55 is connected to the above-described pulling cable 48, which engages on the circumference of the cam plate 47. Thus, the pull cable 48 converts the straight stroke movement of the hinge plunger 55 into a rotary movement of the cam plate 47. The hinge plunger 55 therefore acts as a drive part of the control gear 38. If the door 5 is pivoted downwards from its closed position shown in FIG. 4, the hinge plunger 55 moves downward in the slot 53 in a straight movement in the direction of the arrow shown. The rectilinear movement of the hinge plunger 55 is transmitted to the cam plate 47 via the traction 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 transportation 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. In the event of incorrect actuation of the door handle 17, 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 movement of the hinge plunger 55 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 magnitude of the torque with which the traction cables 43, 48 act on the cam plate 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, for example at the beginning of a Pivoting movement of the door caused by an extension of the pull cables 43, 48 or by a play in the control gear 38 can thus be compensated.

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. A storage space module 79 is arranged below the useful space module 83. 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. In the useful space module 83, the operating and display elements 2 shown in FIG. 1 and an associated control unit are provided. The operating and display elements 2 together with the assigned control unit are functional independently of the storage space module 79.

In contrast to the first exemplary embodiment, the drive movement for the control gear 38 is not generated by the conventional door hinge 49 shown in FIG. Rather, the control gear 38 of the second exemplary embodiment has a rotary shaft 57 as the drive part. 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 in the opposite slide tracks 63 like a guide carriage. 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. Through the open end 26, the housing-fixed bearing roller 65 can be detached from the associated guide rail 25 when the door is removed.

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. 10a, the sliders 60 of the slide slide Guide carriage 59 first upwards. 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 from FIG. 8 and FIG. 10, the rotary shaft 57 is formed with a drive drum 54 which 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 pull rope 43 via a retaining eye 75, as a result of which the first torque M1 is exerted on the door handle 17 in the 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, the tension cables provided on both sides of the door sides can be subjected to the same tension. 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, from which a space 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 sliding piece 60 extends from the starting section 90 into the horizontal section 91 of the sliding track 63. During this movement, the sliding piece 60 of the guide slide 59 presses against the spring-loaded pivot lever 95th 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 position shown in FIG. 11, the swivel lever 95 allows the sliding piece 60 of the guide carriage 59 to start moving from the closed position of the door 5. During this initial movement, the pivot lever 95 is disengaged from the pivot lever 95. According to FIG. 11, the sliding piece 60 only comes into contact with the pivot lever 95 at a pivot 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.
