Description

Domestic dishwasher

The present invention relates to a domestic dishwasher.

The loading and unloading of a lower basket of a dishwasher is often found by users to be uncomfortable, as this requires working in a diffracted mount.

Therefore, various mechanisms have been known from the prior art for raising the lower basket from a lower position thereof within the washing compartment of the dishwasher to an upper position outside the washing compartment. For example, the publications DE 20 2009 004 771 U1 and DE 10 2012 017 993 A1 each describe a sliding / pivot mechanism set up for this purpose. This includes a tray, such as a lower basket, which on a

Guide rail is held linearly displaceable. The guide rail is articulated via two pivot arms on a body of the dishwasher pivotally.

In general, in such sliding / pivoting mechanisms, the problem is that the center of gravity of the lower basket is pivoted so far in front of the body that the entire dishwasher tilts forward. Partially, this is tried

To avoid this problem by not providing a full extract for the sub-basket. However, this in turn results ergonomic disadvantages in the loading and

Discharge of the lower basket.

Against this background, an object of the present invention is to provide an improved domestic dishwasher.

Accordingly, a domestic dishwasher with a body, at least one loading level, at least one guide rail, at least one link arm and a guide device is provided. The at least one loading plane is linearly displaceable along the at least one guide rail between a first and a second position thereof. In the first position is the at least one

Loading level arranged below and inside the body. In the second position, the at least one loading plane is at the bottom and at least partially outside the body arranged. The at least one link arm holds the at least one guide rail for moving the loading plane between the second and a third position thereof pivotally on the body. The at least one loading plane is arranged in the third position above and at least partially outside the body. The guide device guides the at least one link arm along a guideway which at least partially deviates from a preferred circular path.

In other words, the guideway is partially or completely non-circular. Due to the guide device, the loading plane can be controlled so that it remains closer to the body on its way up between the second and third position with its center of gravity. The at least one loading level follows at least partially not a pitch circle movement of the link arm, for example, not known from the prior art quarter-circle movement, but differs from this particular upwards and to the body back from this. Thus, it is possible to extract the at least one loading level in particular completely from the body ("full extension"), without causing a tilting of the

Household dishwasher comes.

The body may in particular comprise a rinsing container. The at least one link arm can be articulated on the washing container, in particular on a fitting thereof.

The loading level can generally be a tray or receptacle, in particular for crockery or cutlery. The loading level is preferably a crockery basket or a cutlery drawer. Particularly preferably, the at least one loading level is a lower dish rack.

"Bottom" and "top" is to be understood in the present case that the third position of the loading level is provided above the first and second positions of the loading level.

In particular, the at least one link arm can be aligned vertically in the first and second positions of the at least one loading plane and horizontally in the third position of the at least one loading plane. "Vertical" and "horizontal" comprise here also deviations from the vertical or horizontal by up to 15 °, preferably less than 10 ° and more preferably less than 5 °.

According to one embodiment, the guideway in the extension direction at least partially an increasing pitch. The extension direction is the direction in which the at least one loading plane is linearly displaceable from the first to the second position. The guideway may thus have different geometric courses; Preferably, it has an increasing slope at least in its initial region. As a result, the at least one loading level is guided particularly close to the carcass.

According to a further embodiment, the guideway has the shape of a half parabola whose apex lies on a longitudinal central axis of the at least one link arm in the first and / or second position of the at least one loading plane.

It has been shown that this shape of a guideway contributes in a simple manner to a particularly narrow guidance of the at least one loading plane on the carcass on its way up from the second to the third position (and vice versa).

According to a further embodiment, the guide means comprises a link guide formed on the body and a handle attached to the arm

Gate element, which engages in the sliding guide. Preferably, the

Slotted guide designed as a slot and / or the link element as a pin.

For example, the slide guide or the slot in a

Rinse container side wall to be formed. According to the above

Embodiments, the slotted guide at least partially have an increasing pitch or the shape of a half parabola, with other forms of slotted guide are possible.

According to a further embodiment, the link arm is set up for rotational and linear relative movement with respect to its point of articulation on the carcass. In particular, the link arm has a slot in which engages a pin arranged on the body.

The pin thus serves as a point of articulation of the link arm on the body, so that a rotational relative movement is made possible. At the same time, however, a linear relative movement is possible due to the slot, with the handlebar can move linearly with the slot opposite the pin. In this case, a first end position of the pin in the slot of the first and / or second position of the at least one loading level and an opposite end position of the pin in the slot of the third position of the at least one loading level can be assigned.

Furthermore, a household dishwasher with a body, at least one loading level, at least one guide rail, at least one link arm and a guide device is provided. The at least one loading plane is linearly displaceable along the at least one guide rail between a first and a second position thereof. The at least one loading plane is arranged in the first position below and inside the body. In the second position, the at least one loading plane is arranged at the bottom and at least partially outside the body. The at least one link arm holds the at least one guide rail for moving the loading plane between the second and a third position thereof pivotally on the body. The at least one loading plane is arranged in the third position above and at least partially outside the body. The guide device is set up to guide the at least one loading plane between the second and third position, preferably on a circular path. The

Circular path deviates from that on which the at least one guide rail is movable.

In particular, the respective circular paths can intersect. The

Guiding device prevents the loading plane between the second and third positions from moving on a circular path whose center coincides with the articulation point of the at least one link arm on the carcass. Rather, the provides

Guide lever that the at least one loading level along the

Guide rail is retracted when the at least one loading level is moved from its second to its third position. Also by this measure is the at least one loading level closer to the body out, as is the case with conventional solutions. Accordingly, the focus of at least one

Loading level moves less far forward, so that the risk of tilting the household dishwasher is avoided. According to one embodiment, the guide device has a guide lever. The guide lever is designed in particular as an elongated element, for example as a plastic or metal profile part.

According to a further embodiment, the guide lever is articulated at its one end to the body and at its other end to the at least one

Loading level in a linear displacement of the same from the first to the second position pivotally engageable engageable.

Thus, if the at least one loading plane is moved linearly from the first to the second position, then it automatically engages with the other end of the guide lever. This engagement is pivotable, so that in the engaged state, only a pivoting of the loading plane to the pivot point of the

Guide lever at one end to the body is possible. A linear one

Relocating the at least one loading level is precluded in the engaged state, however.

According to a further embodiment, the guide device comprises a locking piece or a locking counterpart. In particular, the other end of the guide lever, the locking piece and the at least one loading level, the locking counterpart, wherein the locking piece and the locking counterpart in a release state of the same release a linear displacement of the at least one loading plane relative to the guide lever and lock in a blocking state thereof the linear displacement. The locking piece or the locking counterpart is rotatable for an adjustment of this between the blocking state and the release state about an axis of rotation in the other of the locking piece and the locking counterpart. Preferably, the axis of rotation is coaxial with a pivot axis about which the one end of the guide lever on the at least one

Loading level is articulated. In the locked state, the locking piece and the locking counterpart engage with each other in such a way that the linear displacement of the loading plane is blocked. In particular, the locking counterpart can engage behind the locking piece (or vice versa) in the locked direction. For example, the blocking counterpart can extend around the blocking piece at least in sections, or vice versa. By doing

Release state, however, is a disengagement of the locking piece and the

Lock counterpart in the direction of linear displacement released. Of the

Release state can thus refer to a state in which, for example, the locking piece is still arranged in the locking counterpart, but is movable out of this. Or the release state may refer to a state in which the locking piece and the locking counterpart are spaced from each other.

Characterized in that preferably the axis of rotation is the same axis with the pivot axis, there is a simple mechanism to prevent simultaneous pivoting and linear displacement of the at least one loading plane relative to the guide lever.

In particular, it can thus be prevented that the at least one loading plane, after it has been pivotally engaged in the extension direction with the other end of the guide lever, and a pivoting of the at least one

Loading level has begun from the second position to the third position, against the extension direction, that is, in the rinsing tank, shifted back. Accordingly, such a relocation is preferably excluded until the at least one loading level has been pivoted back completely out of its third position into the second position. Only then is the linear relocation of the at least one loading level released into the washing container. A simple mechanism thus results from the fact that the rotational movement of locking piece and

Lock counterpart to each other in the present solution is a result of the movement of the at least one loading level upwards from the second to the third position, wherein the at least one loading plane pivoted relative to the guide lever. That is, the rotational movement and the pivotal movement take place simultaneously, wherein the pivoting movement is the cause of the rotational movement.

According to a further embodiment, the locking piece or the locking counterpart has a C-shaped element with a radial opening. The other one of the Locking piece and the counterpart counterpart has an insertable by means of the radial opening pin-shaped element.

By linear displacement, the pin-shaped element passes through the radial opening in the space enclosed by the C-shaped element. By relative rotation of the locking piece and the locking counterpart, the C-shaped element engages behind the zapfenformige element against the extension direction, so that a movement of the peg-shaped element against the extension direction is then locked.

According to a further embodiment, the guide lever has a pivot point on the body, which lies below and / or in the extension direction in front of the articulation point of the at least one guide lever. The extension direction is the direction in which the at least one loading plane is linearly displaceable from the first to the second position. Thus, the at least one loading level can be suitably close to the body.

According to a further embodiment, the guide lever is held in position at least in the first and second positions of the at least one loading plane by means of a stop. The stopper may be attached to the body.

Still further, a household dishwasher with a body, at least one loading level, at least one guide rail, at least one link arm and a guide device is provided. The at least one loading plane is linearly displaceable along the at least one guide rail between a first and a second position thereof. The at least one loading plane is arranged in the first position below and inside the body and in the second position below and at least partially outside the body. The at least one link arm holds the at least one guide rail for moving the loading plane between the second and a third position thereof pivotally on the body. The at least one loading plane is arranged in the third position above and at least partially outside the body. The guide device is set up to guide the at least one loading plane along a guideway which

preferably deviates from a circular path. In other words, the guideway is partially or completely non-circular. Due to the guide device, the at least one loading level

or whose center of gravity is guided close to the body between its second and third position. Accordingly, a tilting of the

Household dishwasher are avoided.

According to one embodiment, the guide track runs straight and / or vertically.

From "vertical" here are also deviations from the vertical by up to 30 °, preferably less than 10 ° and more preferably less than 5 °.

In accordance with a further embodiment, the guide device has a guide rail arranged on the carcass, in particular straight and / or vertical, and a guide element arranged on the at least one loading plane. The

Guide element preferably comes by means of linear displacement of the at least one loading level from the first to the second position with the guide rail in abutment. Alternatively or additionally, the at least one is preferably when moving

Loading level between the second and third position, the guide element guided along the guide rail.

Preferably, the at least one loading level is moved from its first to its second position, whereupon the guide element comes into abutment with the guide rail. During the subsequent movement of the at least one loading plane between the second and third position, the guide element is moved along the

Guide rail and thereby pulls the at least one loading plane along the at least one guide rail against the extension direction back when the at least one loading level moves from the second to the third position. The guide element can, for example, only in the extension direction against the

Guide rail abut and are guided perpendicular thereto along it. In addition, the guide rail may be formed as a channel in which the guide element is fixed in and against the extension direction, correspondingly blocking a linear displacement of the guide element in and against the extension direction while the at least one loading plane is moving between the second and third positions.

According to a further embodiment, the guide element as a roll or

Slider formed.

Thus, the guide element can be operated quietly and with little effort operable on the guide rail.

According to a further embodiment, the guide rail comprises two parallel walls, between which the guide element is insertable by linear displacement of the at least one loading level by means of an opening and / or between which the guide element is guided when moving the at least one loading level between the second and third position. Accordingly, the two parallel walls form the aforementioned channel. The opening can be formed, for example, simply in that the front wall of the two parallel walls in the extension direction is shortened and thus releases a movement of the guide element in the extension direction to the other parallel wall. If the guide element is then in abutment with the other wall, the guide element is located directly below the opening between the two parallel walls, by means of which the guide element can be inserted between the two parallel walls.

In the figures, identical or functionally identical elements have been given the same reference number, unless stated otherwise.

Fig. 1 shows a schematic perspective view of a

Household dishwasher 1. The dishwasher 1 has a

Washing container 2 comprehensive body, which is closed by a door 3 watertight.

The rinsing container 2 and the door 3 can form a rinsing chamber 4 for rinsing dishes. The door 3 is shown in Fig. 1 in its open position. By pivoting about a provided at a lower end of the door 3 pivot axis, the door 3 can be closed or opened. The washing container 2 is, for example, cuboidal and may include a bottom 5, a bottom 5 opposite ceiling 6, a door 3 opposite the rear wall 7 and two opposing side walls 8, 9. especially the

Side walls 8, 9 can be made of stainless steel sheet. The dishwasher 1 also has at least one loading level 10. The loading level 10 is preferably a Spülgutaufnahme the dishwasher 1. In particular, a plurality of loading levels 10 may be provided, wherein each one of the plurality of loading levels 10 a lower basket, a top basket or a

Can be cutlery drawer of the dishwasher 1. The several

Loading levels 10 are preferably arranged one above the other in the washing container 2. Each loading level 10 is selectively displaceable in an insertion direction E into the washing container 2 or in an extension direction A out of this. For this purpose, preferably on both sides of a respective loading level 10 a

Rail device 1 1 provided.

2 shows a view II from FIG. 1 according to a first variant, wherein the side wall 9 is not shown, so that a view of the side wall 8 and the rinsing chamber 4 lying in front of it is released. Further, in Fig. 2, a loading level 10 is shown in the form of a lower dish rack.

The dish rack 10 is opposite to a guide rail 12 of the already in

Connection with Fig. 1 said rail device 1 1 linearly displaceable. For this purpose, the dish rack 10 may for example comprise a further guide rail 13, which is linearly displaceable by means of not shown roller bearing and a running rail, not shown, with respect to the guide rail 12. The guide rails 12 and 13 together form a so-called telescopic rail. Alternatively, the

Dish rack 10 also have rollers, by means of which it is held linearly displaceable on the guide rail 12. The dish rack 10 has a first, not shown, position in which it is inserted in the insertion direction E in the washing chamber 4 and arranged close to or in abutment against the rear wall 7. Further, the dish rack 10 is disposed in the first position in a lower portion of the washing chamber 4 near the bottom. In contrast, Fig. 2 shows a second position of the dish rack 10, in which this is linearly displaced in the extension direction A partially from the washing chamber 4 out. The dish rack 10 could also be completely shifted out of the washing chamber 4 (so-called full extension). This movement corresponds to an exclusively horizontal displacement of the crockery basket 10. "Horizontal" also includes in the present case

Deviations of less ± 20 °, preferably less ± 10 ° and more preferably ± 5 °.

At the second position, a third position of the shown in Fig. 3 now closes

Dish rack 10 on. In the third position, the dish rack 10 is up

pivoted and arranged outside the washing chamber 4. For the purpose of movement from the second to the third position, the domestic dishwasher 1 according to this first variant has a mechanism described below with reference to FIGS. 2 to 4. FIGS. 2 and 3 each show a parallelogram link arrangement 14, which comprises, for example, two link arms 15, 16. The link arms 15, 16 are each - in the following, however, explained in more detail for the sake of simplicity only for the link arm 15 - hinged to the side wall 8 at one end to a pivot point 17. At its other end, the link arms 15, 16 on the guide rail 12 at a

Anlenkpunkt 18 hinged.

In order to move the dish rack 10 from the second to the third position, the handlebar arms 15, 16 can be pivoted by 80 °, for example, as shown. However, a corresponding maximum pivot angle between, for example, 60 ° and 90 °. In the second position (this also applies, by the way, to the first position (not shown)), the link arms 15, 16, as shown in FIG. 2, can be aligned vertically. This position take the link arms 15, 16 in particular due to the effect of gravity. The dish rack 10 may be fixed in the second position relative to the guide rail 12 linear immovable, for which purpose a corresponding locking mechanism may be provided. In order to prevent the dish rack 10 from pivoting too far in front of the handlebar arms 15, 16, that is to say in the extension direction A, the washing container 2 moves and potentially leads to a tilting of the household dishwasher 1, a guide device 19 is provided. The guide device 19 comprises a slotted guide 20 and a link element 21.

The slide guide 20 is formed for example as a slot on or in the side wall 8. The slotted guide has, for example, an at least partially increasing slope in the extension direction A. For this purpose, the link guide, for example, have the shape of a half parabola whose apex S is located on a longitudinal central axis 22 of the link arm 15, when this is in its vertical position, that is according to the first and the second position of the dish rack 10th

The link element 21 may be formed, for example, as a pin which is attached to the link arm 15 and protrudes from this and hineinerstreckt into the slotted guide 20. In addition, it can be provided that the pin 21 is held in the sliding guide 20 in a form-fitting manner, for example by means of a dovetail geometry. The positive connection (for example, due to the

Dovetail geometry) thus exists in a width direction B of

Dishwasher 1. The link arm 15 also has a slot 23 through which in the

Width direction B (see Fig. 4), a pin 24 which is attached to the washing container 2 extends. The pin 24 forms together with the slot 23 the aforementioned pivot point 17. As the dish rack 10 pivoted from its second to its third position, the link arm 15 can pivot accordingly not only about the pin 24, but also a linear relative movement with respect to the pin 24 execute. The linear relative movement is due to the interaction of the

Gate element 21 causes the slide guide 20, wherein the slot 23 moves relative to the pin 24. The slotted guide 20 thus defines a non-circular guideway for the link element 21 and thus for the dish rack 10th

In this embodiment, the pin 24 always forms the instantaneous pivot point with respect to which the dish rack 10 is pivoted. However, due to the changes Guide means 19, the distance between the dish rack 10 and a center of gravity SP thereof and the pin 24 continuously when the

Dish rack 10 pivoted from its second to its third position (and vice versa). The guide device 19 modifies the actual, approximately

Quarter circle movement of the control arms 15, 16 such that the dish rack 10 and thus also its center of gravity SP is guided narrowly on the washing container 2 and accordingly tilting of the dishwasher is avoided.

A second variant of a mechanism will be described below with reference to FIGS. 5 to 8, which allows the dish rack 10 or its

Focus SP close to the washing container 2 to lead upward when it is moved from its second to its third position, so that a tilting of the

Dishwasher 1 is avoided.

In contrast to the first variant according to FIGS. 2 to 4, the mechanism comprises a guide device 25 with a guide lever 26. The guide lever 26 is pivotable at its one end 26a on the washing container 2, in particular the

Sidewall 8 pivotally hinged. Preferably, the end 26 has a pivot point 28 on the side wall 8, which under and in the extension direction A in front of the

Linkage point 17 of the link arm 15 (door-side link arm) is located. At its other end 26b, the guide lever 26 has a locking piece 27 enlarged in FIGS. 7 to 9. The locking piece 27 is designed for example as a non-rotatable pin which extends in the width direction B of the household dishwasher 1. A cross-section of the pin 27 can taper in a withdrawal position E shown in FIGS. 5 and 7 from a side 27a of the same towards a side 27b thereof. The sides 27a, 27b may be rounded. In particular, the pin 27 may have a flattened on both sides circular cross-section, as can be seen for example in Fig. 7. On the dish rack 10, a blocking counterpart 30 corresponding to the blocking piece or pin-shaped element 27 is fixed in a rotationally fixed manner, which is shown enlarged in FIGS. 7 to 9. The locking counterpart 30 is embodied, for example, as a C-shaped element with a radial opening 31. By means of the radial opening 31, the C-shaped element 30 can be moved over the peg-shaped element 27 when the dish rack 10 is moved linearly from its first position (not shown) to its second position shown in FIG. The tapered cross section of the pin-shaped element 27 serves as an insertion aid. "Radial" here refers to the longitudinal axis of the pin-shaped element 27 or of the C-shaped element 30, which extends in the width direction B.

In its waiting position 25, the guide lever 26 is against a stop,

for example in the form of a pin 32 on the side wall 8 at. The guide lever 25 is in both the first and in the second position of the dish rack 10 in the waiting position.

Also, the peg-shaped element 27 and the C-shaped element 30 are in the first and second positions of the dish rack 10 in a release state, that is, a linear displacement of these relative to each other in the extension direction A or the insertion direction E is possible.

Since the peg-shaped element 27 rotatably connected to the guide lever 25 and the C-shaped member 30 rotatably connected to the dish rack 10, a pivoting of the crockery basket 10 from the second in its third position leads to a rotation of the pin-shaped element 27 about a rotation axis D ( is at the same time the above mentioned

Longitudinal axis) in the C-shaped element 30. This in turn causes the C-shaped element 30, the pin-shaped element 27 on the side 27a increasingly engages behind. 8 corresponds to an intermediate position of the dish rack 10 between its second position shown in FIG. 7 and its third position shown in FIG. 9. Thus, in the intermediate position and the third position of the crockery basket 1, a blocking state, in which a linear displacement of the crockery basket 10 in the

Pulling direction A and locked in the insertion direction E, which is a

Locking state of the pin-shaped element 27 and the C-shaped member 30 corresponds. At the same time results from the fact that the dish rack 10 is forcibly pivoted on a circular path whose center corresponds to the articulation point 28 of the guide lever 25 on the washing container 2. According to the second variant, the link arms 15, 16 are exclusively rotatable, ie not slidably provided with respect to their respective pivot points 17 on the rinsing container 2, as in the case of the first variant (FIGS. 2 to 4). Accordingly, the dish rack 10 shifts relative to the guide rail 12 to follow the predetermined by the guide lever 25 circular path can.

In particular, the dish rack 10 is pushed back during its movement from the second to the third position along the guide rail 12 (ie in the feed direction E moves). Accordingly, the dish rack 10 or its center of gravity SP can also be moved close to the washing container 2 in the second variant, whereby tilting of the domestic dishwasher 1 is avoided. Characterized in that a pivot axis SW (see Fig. 7), around which the dish rack 10 relative to the

Guide lever 25 is pivoted, is coaxial with the axis of rotation D, the

Lock state and the release state are provided in a mechanically simple manner.

With reference to FIGS. 10 and 11, a third variant of a mechanism will be explained below, which is intended to reliably prevent tilting of the household dishwasher 1. In contrast to the second variant according to FIGS. 5 to 9, the positive guidance of the dish rack 10 in the third variant takes place by means of a

Guide device 33, which includes a guide rail 34. The guide rail 34 extends in the vertical direction. The guide rail 34 may include two side walls 34a, 34b. The side walls 34a, 34b may face each other in the extension direction A. The lying in the extension direction A in front of the side wall 34a

Side wall 34b may be formed shortened at a lower portion 36 of the guide rail 34. Thus, a way for a mounted on the dish rack 10 guide member 37 of the guide device 33 is released so that it comes in linear displacement of the dish rack 10 from its first position, not shown, into its second position shown in Fig. 10 into contact with the side wall 34a , Further pulling out of the crockery basket 10 in the direction A is thus blocked. The dish rack 10 can now be moved in the vertical direction along the guide rail 34 from its second position (see FIG. 10) to its third position (see FIG. 11). In this case, the guide element 37, which may for example be designed as a roller passes through a vertical opening 38 between the two side walls 34a, 34b, so that after leaving the second position, a linear displacement of the dish rack 10 in the extension direction A and locked in the feed direction E. is. As in the second variant, the handlebar arms 15, 16 result in a movement of the guide rail 12 on a circular path even in the third variant. Nevertheless, to allow the linear movement of the dish rack 10 in the vertical direction, the dish rack 10 moves relative to the guide rail 12. In particular, the dish rack 10 is pushed back along the guide rail 12 as it passes from its second to its third position.

Accordingly, even in the third variant, the dish rack 10 or its center of gravity SP can be guided close to the washing container 2 upwards, so that tilting of the household dishwasher 1 can be safely avoided.

Although only shown for the first and second variants (see Fig. 3 and Fig. 6), also in the third variant, a full extension can be displayed, that is, the dish rack 10 is located completely outside the washing chamber 4 in its second position. For this purpose, the guide element 37 can be held with a corresponding spacer on the dish rack 10.

In general, moving the dish rack 10 between its three

Positions manually or partially or fully automated. For example, an electric motor can be provided which pivots the link arms 15, 16 about their respective pivot points 17. Alternatively or additionally, a spring may be provided, which performs this task in at least one pivoting direction.
