Description

Domestic dishwasher

The present invention relates to a domestic dishwasher. A domestic dishwasher has a rinsing container and at least one dishwashing item to be moved into and out of the rinsing container. The dishwasher may have a plurality of washware receptacles arranged one above the other, such as a lower basket, an upper basket or a cutlery basket. Since the lower basket is located near a bottom of the washing container, loading and unloading of the lower basket requires the user to kneel down or stoop to the lower basket.

This is partly perceived as uncomfortable, which is why known from the prior art so-called. Lower Rack Elevation - systems have become known, ie lifting devices for at least partially automatic lifting of the lower basket. For example, DE 10 2014 210 721 A1 describes such a lifting device.

The problem with such systems is that when raising the lower basket must be ensured that there is no collision with the upper basket. Although, for example, DE 10 2014 210 721 A1 describes how a position of the lower basket during lifting can be fixed in such a way that it no longer moves linearly horizontally along the guide rail which supports it, which is achieved there by two interlocking locking pieces , However, it can still come to a collision with the upper basket when it is at least partially pulled out.

It is therefore an object of the present invention to provide an improved domestic dishwasher. Accordingly, a domestic dishwasher with a lower and an upper Spülgutaufnahme, a first sensor device for detecting a position of the upper Spülgutaufnahme, a drive device and a control device, which is arranged, in response to the detected position of the upper Spülgutaufnahme the drive means for raising the lower Spülgutaufnahme to control provided.

By the position of the upper Spülgutaufnahme is detected, a collision check by the control device can take place. Depending on the result of this collision check, then the lower Spülgutaufnahme is raised or not. It is also conceivable that the lower Spülgutaufnahme is raised only slowly and a warning signal is issued to a user. Accordingly, a collision of lower and upper Spülgutaufnahme or a collision of these associated mechanisms, such as swivel arms and / or guide rails can be avoided.

The collision test can be designed in many ways. In the simplest case, only a single position of the upper Spülgutaufnahme is detected, for example by a switch which is triggered in an end position or other defined position by means of the upper Spülgutaufnahme. The collision check of the control device is then simply to detect whether a corresponding signal of the switch is applied. If so, the bottom sink will be raised, if not, it will stay in place.

In other embodiments, in turn, the positions of the lower and upper Spülgutaufnahmen can be detected in real time (real-time). The positions may relate to both X-positions and Z-positions, wherein X means the horizontal axis along which the lower and upper Spülgutaufnahme can be moved out of a washing container of the dishwasher and into this, and Z means the vertical axis. The control device then controls the drive device in real time on the basis of a spatial model for each XY position, or stops or slows down the lifting process.

The first sensor device-as well as the second sensor device mentioned later-can be designed, for example, as a switch, magnetic sensor, in particular a reed or Hall sensor, or an optical sensor, especially a light barrier or laser distance meter The first and / or the second sensor device can be equipped with one or more measuring objects cooperate to detect the position of the upper or lower Spülgutaufnahme. The measured object - also referred to as a target - may, for example, be a magnetic element, in particular of permanent magnetic material.

The drive direction can be e.g. be designed as an electric motor.

The detected position may mean, as mentioned above, that a large number of positions or even only two positions (switch actuated or not) are detected. The detected position may be the position of the upper Spülgutaufnahme in X. In addition, the position of the upper Spülgutaufnahme can be detected in Z. The drive device may be configured to generate the entire force required to lift the lower washware receptacle. In other embodiments, it may only generate an assisting force. In this case, it is preferably provided that a sensor device detects an actuating force applied by the user. The drive device then raises the lower Spülgutaufnahme as a function of the detected actuation force, so only produces a required for raising the lower Spülgutaufnahme partial force.

Basically, the raising of the lower Spülgutaufnahme can take place between a first and a second position thereof, wherein it is arranged higher in the second position than in the first position. Optionally, in the vertical direction, an upper side of the lower washware receptacle in its second position can be arranged at the same height as or just below (meaning a maximum of 10, preferably a maximum of 5 cm below) a lower side of the upper washware receptacle, wherein "side" means each upper or upper washware receptacle In the second position of the lower washware receptacle in the horizontal direction a rear side thereof may be arranged in front of a front side of the upper washware receptacle, wherein "Side" each rear or front boundary of the lower or upper Spülgutaufnahme means, for example. An outermost wire or an extreme plastic part. In the first position of the lower Spülgutaufnahme this can in the vertical direction, for example, with the same touch a horizontal door inner wall of the domestic dishwasher or else be arranged in the vicinity of the horizontal door inner wall. Furthermore, the lower one Spülgutaufnahme in the first position preferably completely or at least predominantly (greater than 50% of its length) pulled out of the washing.

The control device can be designed as a computer device, in particular a microprocessor.

According to one embodiment, a second sensor device for detecting a position of the lower Spülgutaufnahme is provided, wherein the control device is adapted to control the drive means for raising the lower Spülgutaufnahme depending on the detected position of the lower and upper Spülgutaufnahme.

This embodiment is particularly advantageous when the movement path of the lower Spülgutaufnahme can vary, in particular depends on the behavior of the user, such as the lower Spülgutaufnahme is horizontally freely movable along its guide rail horizontally, while it is raised. In contrast, the path of movement of the lower Spülgutaufnahme on the other hand always known, that is not variable, as for example in the solution described in DE 10 2014 210 721 A1 or in the following figures 4 to 7 due to the locked by means of the locking piece and locking counterpart horizontal movement of lower Spülgutaufnahme along the guide rail during pivoting of the lower Spülgutaufnahme is the case, a detection of the position of the lower Spülgutaufnahme can be omitted. In embodiments, therefore, it may be provided that only the position of the upper Spülgutaufnahme is detected, i. the position of the lower Spülgutaufnahme is not detected, which advantageously leads to a simpler control.

According to a further embodiment, the control device is adapted to compare the detected position of the upper Spülgutaufnahme with a first release condition and / or the detected position of the lower Spülgutaufnahme with a second release condition, and only to drive the drive means for raising the lower Spülgutaufnahme, if the first and / or second release condition is met. As already mentioned above, the position of the first and second items to be washed in X and possibly in Z can be detected. Accordingly, the first and / or second release condition (in each case) have an X and possibly a Z coordinate.

According to a further embodiment, the domestic dishwasher has a washing container, wherein the first release condition is met when the upper Spülgutaufnahme an end position is in which it is inserted into the washing compartment.

"Inserted" means that the upper washware holder is pushed against a rearward stop This stop may result from the interaction between the guide rail, the upper washware holder and the fastening of the guide rail to the washbasin side wall.

According to a further embodiment, the second release condition is met when the lower Spülgutaufnahme is in an end position in which it is at least partially pulled out of the washing.

Ultimately, the end position of the lower Spülgutaufnahme should be defined so that it comes in the subsequent lifting process - whose movement is usually already known - no collision with the upper Spülgutaufnahme. The lower Spülgutaufnahme may protrude in its final position, for example, to over 50% from the washing. Alternatively or additionally, the lower Spülgutaufnahme be drawn in its final position against a front (corresponding to the front of the appliance household dishwasher) stop. The stop may result from the engagement of a locking piece fastened to the lower dishwashing station and a counter-locking piece provided on a drag lever. In general, the stop can result from an interaction of the lower washware receptacle or its guide rail with a container-side stop in the horizontal direction. According to a further embodiment, the household dishwasher comprises a guide device, along which the lower Spülgutaufnahme in the washing in a linear, horizontal direction and out of this is displaced, at least one driven by means of the drive means pivot arm, which on the one hand the guide means and on the other hand hinged to the washing container, and a drag lever, which on the one hand hinged to the washing and on the other hand with the lower Spülgutaufnahme in the end position is engageable to the lifting of the same with the aid of the drive means, the movement of the lower Spülgutaufnahme to control in the linear, horizontal direction.

With the help of the drag lever advantageously the movement of the lower Spülgutaufnahme is controlled, in particular limited in one direction out of the washing. The guide device may be, for example, at least two guide rails, which run together on the telescopic principle. Alternatively, the guide device may be a guide rail in which rollers run.

In accordance with a further embodiment, the drag lever has a locking counterpart which can be brought into engagement with a locking piece arranged on the lower flushing goods receptacle, wherein the blocking piece and blocking counterpart are rotated relative to one another during lifting of the lower washware receptacle such that displacement of the lower washware receptacle relative to the drag lever in FIG the linear direction is locked.

Accordingly, as already stated in the introduction, the movement path of the lower washware receptacle is defined in this embodiment, so that basically the second sensor device can be dispensed with. On the other hand, however, the second sensor device in this embodiment can serve to check whether the locking piece and locking counterpart have ever engaged with each other.

According to a further embodiment, the detection of the position of the upper Spülgutaufnahme on detecting their position in the horizontal direction and vertical direction, wherein the control device is adapted to depending on the detected position of the upper Spülgutaufnahme in the horizontal and vertical directions, the drive means for lifting to control the lower Spülgutaufnahme. According to this embodiment, therefore, the position of the upper Spülgutaufnahme is detected in the X and Z direction and taken into account when lifting the lower Spülgutaufnahme. In particular, the upward movement of the lower Spülgutaufnahme is stopped when they are at the same height with (and in the horizontal direction) of the above ren Spülgutaufnahme is located to avoid a collision of the lifting mechanism with the upper Spülgutaufnahme.

According to a further embodiment, the domestic dishwasher comprises a guide device, along which the upper Spülgutaufnahme in the washing in a linear, horizontal direction and out of this is displaced, one of the first sensor means associated measurement object attached to the upper Spülgutaufnahme in the linear, horizontal direction is.

As a result, the position of the upper washware receptacle in the X direction (linear, horizontal direction) can be easily detected. With regard to the design of the guide device, the above applies.

According to a further embodiment, the measurement object of the first sensor device is fixedly mounted in the vertical direction on the upper Spülgutaufnahme.

As a result, a position of the upper washware receptacle in the Z direction (vertical direction) can also be detected with the aid of the first sensor device. This is particularly advantageous for height-adjustable Spülgutaufnahmen. In this embodiment, the first sensor device may preferably be associated with a plurality of measurement objects, which are each fixedly attached to the upper washware receptacle. As a result, the detection of the position in the X and Z directions can be represented metrologically simply.

According to a further embodiment, the domestic dishwasher comprises a height adjustment device with the aid of which the upper Spülgutaufnahme is adjustable in the vertical direction relative to the guide means, wherein the height adjustment device has a stationary portion in the vertical direction, on which the measurement object of the first sensor device is mounted.

Height adjustment for household dishwashers are well known and serve to create more space above the upper Spülgutaufnahme to order there, for example, pots, long-stemmed glasses or the like. If now only the position of the upper Spülgutaufnahme be detected in the X direction, it would - depending on the embodiment of the first sensor device - a Adjustment of the upper Spülgutaufnahme in their height (as a result of the operation of the height adjustment by the user) lead to a measurement error in the corresponding measurement. Advantageously, however, according to the present embodiment, the measurement object is attached to such a portion of the height adjustment device, which at an operation thereof for the purpose of adjusting the upper Spülgutauf- height does not move in height, so is stationary. This section of the height adjustment device is typically attached directly to the guide device.

According to a further embodiment, the household dishwasher comprises a guide device, along which the lower Spülgutaufnahme in the washing in a linear, horizontal direction in and out of this is displaced, one of the second sensor means associated measurement object attached to the lower Spülgutaufnahme in the linear, horizontal direction is. As a result, the position of the lower Spülgutaufnahme can be detected in the X direction in a simple manner. In particular, the measurement object may be provided on a plastic injection-molded component, in particular integrated therein. The plastic injection-molded component can be detachably fastened, in particular clipped, to a basket of the washware receptacle.

According to a further embodiment, the measuring object associated with the second sensor device is fastened to the locking piece.

Thereby, the position of the locking piece can be detected. From the position of the locking piece can be deduced whether this is in engagement with the locking counterpart or not.

According to a further embodiment, the household dishwasher comprises a washing container with a wall, on or behind which the first and / or second sensor device is mounted.

Advantageously, the first and / or second sensor device can be so easily installed and is also protected against corrosion. According to a further embodiment, the drag lever has the second sensor device.

As a result, the second sensor device can be arranged close to the measurement object in its end position, which simplifies detection in terms of signal technology (for example, a smaller coil can be used).

According to a further embodiment, the domestic dishwasher comprises an input device for detecting an input of a user and an output device for outputting an output to a user, wherein the control device is adapted to the drive device for the detected input and satisfied first and / or second release condition Actuate lifting the lower Spülgutaufnahme and control the output device to output the output to the user at the detected input and unfulfilled first and / or second release condition.

Using the input device, the user can tell his Wusch to raise the lower Spülgutaufnahme. The controller then checks to see if the required release condition (s) exist. If this is the case, it lifts the lower Spülgutaufnahme. Otherwise, it signals to the user that this is not possible. The user then has the opportunity to intervene, for example, he may possibly fully insert the upper Spülgutaufnahme, further pull out the lower Spülgutaufnahme or remove high items from the lower Spülgutaufnahme to avoid collision with the upper Spülgutaufnahme when lifting the lower Spül- gutaufnahme. The input can be made, for example, acoustically (in particular voice control), haptically (in particular buttons such as switches or buttons), inductively (in particular inductive detection of a finger of the user) or optically (in particular detection of a gesture by the user). According to a further embodiment, the output comprises an acoustic, optical or haptic information. The output device for the acoustic information is a loudspeaker. Optical information can be output, for example, by means of a single diode or a display. A haptic feedback is conceivable in particular in the constellation that the drive means - as stated in the introduction - only generates an assisting force. In this case, the output device can be realized by the drive device itself, which in this case generates no assisting force and the user accordingly experiences a difficult actuation, or else the drive device can work against the actuating force applied by the user. As an alternative or in addition, the drive device can generate a haptic-experienced shaking effect on the lower washware receptacle. The input device is formed, for example, as the already mentioned by way of introduction sensor device for detecting an applied by the user on the lower Spülgutaufnahme operating force.

According to another embodiment, the input device haptically detects the input, and the output device optically outputs the output, wherein the input device and the output device are arranged adjacent to each other.

As used herein, "adjacent" means that the input and output device are both in the field of vision of a user operating the input device. Desire perceivable.

This ensures that the locking counterpart against the drag lever rotated 34 30 and the locking piece 33 more than the initial position shown by mere adjustment of the lower Spülgutaufnahme 10 from its in FIG. 1, P _A in their in Fig. End position P shown 2 _E of Case would be. The twisting device 48 can be rotatably mounted on the drag lever 30 about the horizontal axis of rotation 35 (see FIG. 5). A free nose 49 thereof is actuated when lifting the lower Spülgutaufnahme 10 from its original position P _A using a container side and stationary, not shown, actuating element, which leads to a pivoting of the nose 49 and corresponding to a rotation of the counterpart counterpart 34 about the locking piece 33 ,

Due to the engagement of locking piece and locking counterpart 33, 34, it is ensured during the entire lifting and lowering operation of the washware receptacle 10 that the lower washware receptacle 10 remains in its fully extended position.

7 illustrates in a partial section in the region of the bearing 32 an alternative arrangement of the sensor device 44. This is behind the side wall 8 of the washing container 2, in particular in the gap between the housing wall 27 and the side wall 8, opposite the measuring object 47 in the starting position P. _A or the end position of the lower Spülgutaufnahme 10 is arranged. Accordingly, the sensor device 44 does not come into contact with the rinsing liquor in the rinsing chamber 4 and is well protected from corrosion. 8 shows an enlarged detail of FIG. 1. 8, the dishwasher 1 comprises a sensor device 50 (in the present case also referred to as a "first" sensor device), which is designed as a reed or Hall sensor, for example. net. The measuring object 51 is, for example, a magnetic element, in particular of permanent magnetic material.

A height adjustment device 52 couples the upper Spülgutaufnahme 1 1 with the above-mentioned, not shown detailing guide device 13 (for example, an upper guide rail). With the help of the height adjustment 52, the upper Spülgutaufnahme 1 1 can be adjusted in height, in particular to create space for larger items above or below the same. For the adjustment, the height adjustment device 52 has a manually operable lever 53a. Furthermore, the height adjustment device 52 comprises a stationary section 53b in the vertical direction Z during the operation of the dishwasher 1, in particular also during the height adjustment. Nevertheless, the section 53b moves in the horizontal direction X with the upper Spülgutaufnahme 1 1 when it is moved out of the washing container 2 and into this. The measuring object 51 is advantageously attached to the section 53b according to the first variant. The sensor signal generated by the sensor device 50 is thus independent of a height adjustment of the upper Spülgutaufnahme 1 1. From the sensor signal, the control device 25 close to the X position of the upper Spülgutaufnahme 1 1, in particular whether this is in its rear end position, i. in its fully inserted into the Spülbe- container 2 position is located.

According to a second variant, a sensor device 50 '(also referred to herein as a "second" sensor device) is provided, to which several measurement objects 51' are assigned, which are attached directly to the upper washware receptacle 11 and therefore follow their movement in the X and Z directions From the arrangement of the measuring objects 51 'detected with the aid of the sensor device 50', the control device 25 can close to the X and Z position of the upper washware receptacle 10. For example, the control device 25 stops the upward movement of the lower washware receptacle 10 when this is in the Z direction at the same height with and in the X direction in front of the upper Spülgutaufnahme 1 1, to avoid a collision, in particular of the pivot arms 18, 19 with the guide rails of the upper Spülgutaufnahme 1 1. The sensor devices 50, 50 'can be signal-coupled to the control device 25 with the aid of cables 54, 54'. Furthermore, the sensor devices 50, 50 'can be arranged behind the rear wall 7 or one of the side walls 8, 9 in order to protect them from corrosion. In this case, the sensor devices 50, 50 'are preferably arranged approximately in the opposite direction of their respective associated measuring objects 51, 51' in the end position of the upper Spülgutaufnahme 1 1.

Finally, FIG. 9 schematically shows a possible embodiment of a circuit of the dishwasher 1. By actuating an input device 55, for example a mechanical button or a touch screen, the user notifies the control device 25 that an increase in the lower washware receptacle 10 is desired. In other embodiments, the input device 55 may be configured to detect an actuation force F _x (see FIG. 1) that the user applies to the lower washware receptacle 10 or its handle 12 in the (positive) X-direction.

The input device 55 transmits the control device 25 a corresponding signal. Subsequently, the control device 25 checks whether the X and possibly Z positions of the upper washware receptacle 1 1 detected by means of the sensor devices 44, 50, 50 'and the detected X position of the lower washware receptacle 10 on the control device 25 or a memory thereof fulfilled release conditions. The release conditions can be stored, for example, in the form of an allowed maximum distance between the respective sensor device 44, 50, 50 'and their respective associated measurement object (or measurement objects) 46 or 51, 51'. In particular, as a release condition for the upper Spülgutaufnahme 1 1 deposited that this is in its retracted end position. For the lower Spülgutaufnahme 10 is preferably deposited as a release condition that this is in its lower, extended end position (corresponding to the starting position P _A ). If the release conditions are all fulfilled, the control device 25 activates the drive device 24, which then raises the lower washware receptacle 10. Otherwise, the control device 25 outputs a warning sound via an output device 57 in the form of a loudspeaker to the user. Additionally or alternatively, the user via an optical output device 56 in the form of an LED or a display be given a warning. For example, the LED may light up or change color. Preferably, the optical output device 56 is arranged adjacent to the input device 55 in such a way that both lie in the field of view B of the user making the input (an eye is indicated schematically).
