HOUSEHOLD DISHWASHER

Description

[0001] The present invention relates to a household dishwasher.

[0002] The operation of household dishwashers is intended to be increasingly simplified. One aspect of this is that a user's request to open the door is recorded electronically.

[0003] Document DE 10 2010 037 397 A1 discloses a household dishwasher with an opening drive configured to move the door from a closed position to a partially open position. For this purpose, a sensor is provided for detecting an acoustically expressed opening request from a user. Documents EP 1 935 313 ​​B1 and EP 2 280 631 B1 disclose a household dishwasher with a door and a decorative panel spring-mounted on the door. Furthermore, a sensor is provided for detecting a movement of the decorative panel relative to the door and thus a request to open the door.

[0004] The document EP 2 497 405 A2 discloses a household dishwasher with a knock sensor for detecting an acoustic knock signal input by the user and with an evaluation unit.

[0005] The document DE 10 2015 211495 A1 discloses a dishwasher with a washing container, a lower and an upper dishware holder, wherein the lower dishware holder can be moved in and out of the washing container by means of a drive device, and furthermore this drive device can be controlled as a function of an actuating force on a handle of the dishware holder.

[0006] Against this background, it is an object of the present invention to provide an improved household dishwasher.

[0007] This object is achieved according to the invention by a household dishwasher according to the independent claim. Accordingly, the household dishwasher comprises a dishware holder and a sensor unit configured to generate a sensor signal as a function of a change in the position of the dishware holder and / or a force acting on it.

[0008] The dishware holder can therefore be used advantageously, particularly as a control element for the household dishwasher.

[0009] A "dishwasher basket" in this case is a basket, especially a basket, for holding dishes to be cleaned, such as plates, cups, cutlery, or bowls. According to the invention, this is an upper dishwashing basket, also known as an upper dish basket. A dishwashing basket can also be a lower dishwashing basket, also known as a lower dish basket, or a cutlery drawer.

[0010] It may be provided that multiple washware receptacles are provided, and that the sensor unit detects a change in the position of multiple washware receptacles and / or a force acting on multiple washware receptacles. However, it may also be provided that multiple sensor units are provided, and that each sensor unit detects the change in the position of a respective assigned washware receptacle and / or the force acting on a respective assigned washware receptacle.

[0011] A "change of position" in this context refers to a translational and / or rotational movement of the dishware holder. The translational movement can be along one, two, and / or three (particularly mutually orthogonal) axes. The rotational movement can be about one, two, and / or three (particularly mutually orthogonal) axes. The change of position can also be a movement that includes both a translation and a rotation along or about the one, two, and / or three axes. The movement is, in particular, one that is triggered by a short pulse.

[0012] In this context, a "force application," in particular a change in force, is understood to mean a force exerted on the dishware holder, which is directly measured by the sensor unit. The force application on the dishware holder can be caused, in particular, by a human or by a robot. In particular, a user can directly or indirectly cause the change in position of the dishware holder and / or the application of force to it. A direct application means that the user acts directly on the dishware holder with their hand or another body part. An indirect application means that one or more other components of the household dishwasher, such as a door, are connected between the force application by the user and the dishware holder. For example, the user presses on the door, causing the dishware holder to move (change in position).

[0013] According to the invention, a control unit is provided which is configured to detect a user interaction with the household dishwasher. The user interaction can, in particular, be a user request to open the door. Other types of user interaction can, for example, be the selection of a specific washing program, a retraction or extension movement of the dishware holder, and / or the operation of a user interface.

[0014] According to the invention, the household dishwasher comprises a washing compartment and a door for closing or opening the washing compartment. When the door is closed, the user of the household dishwasher can act on the door, for example, by pressing it, in such a way that this causes a change in the position of the dishware holder. In this case, the door and the dishware holder are coupled to each other, so that a force acting on the door causes a change in the position of the dishware holder. To achieve this, the dishware holder can be pressed against the door, for example, by a spring system.

[0015] The dishwashing basket can also be used to detect a fault condition. A fault condition could be, in particular, an overload of the dishwashing basket. Another fault condition could be that an object is blocking or preventing the dishwashing basket from moving in or out. Another fault condition could be one or more defective components of the household dishwasher.

[0016] In particular, one or more target position changes of the dishware holder and / or target force effects on it can be stored on the control unit or a data storage device thereof. These target values ​​are compared with the actual position changes and / or actual force effects detected by the sensor unit in order to determine an error condition.

[0017] If the control unit detects a fault condition, the control unit can be configured to trigger an alarm device on the household dishwasher. An alarm device can, for example, be an audible and / or visual alarm device. Alternatively or additionally, the control unit can inform the user of the fault condition via an application on an external device, such as a smartphone.

[0018] According to the invention, an actuator and a control unit are provided, wherein the control unit is configured to control the actuator in dependence on the sensor signal. In particular, the actuator is an electric motor.

[0019] According to one embodiment, the actuator is configured to move the dishware holder into and / or out of a washing compartment of the household dishwasher and / or to raise and / or lower the dishware holder. In particular, the actuator can move the dishware holder (or alternatively, the door of the household dishwasher) directly or by means of a gear mechanism, for example, a gear and / or lever. In the case of the door, the actuator pivots it at least partially.

[0020] In particular, it is conceivable that the user of the household dishwasher moves the dishware holder in an outward or inward direction. This change in position is interpreted by a control unit as user interaction, meaning that the user wishes to extend or retract the dishware holder. In response to this user interaction, the control unit controls the actuator, which is configured to automatically move the dishware holder out of or into the washing tub. It is also conceivable that the actuator merely provides force-assisted extension or retraction by the user.

[0021] The actuator can also be used to raise and / or lower the dishware holder. For example, it is conceivable that the dishware holder is a lower dishware holder that is raised when extended to increase user comfort when loading and / or unloading the dishwasher. In this case, too, the actuator can raise and / or lower the dishware holder automatically or provide the user with force-assisted raising and / or lowering of the dishware holder.

[0022] According to the invention, a rinsing container and a door for closing or releasing the rinsing container are provided, wherein the actuator is configured to open and / or close the door and / or to unlock and / or lock a door lock of the door.

[0023] For example, it can be provided that when the door closes the wash tub, the user pushes the door towards the wash tub and that this force exerted by the user on the door results in a change in the position of the washware holder. This change in position is detected by the sensor unit and interpreted by the control unit as a request to open the door. The control unit then controls the actuator in such a way that a door lock is unlocked and / or the door is opened at least a crack. It can also be provided that the user moves the washware holder towards the wash tub. This movement causes a change in the position of the washware holder, which is detected by the sensor unit. This change in position is recognized by the control unit as a request to close the door. The control unit then controls the actuator in such a way that the door is closed and a door lock is locked.

[0024] According to the invention, a damping element is provided which, when the door is closed, is arranged between the dishware holder and the door and which is designed to dampen a stop of one of the door and the dishware holder against the other.

[0025] This prevents damage to the dish rack and the door. A material with damping properties, such as an elastomer, can be considered as a damping element. Other possible damping elements include spring systems or magnetic systems.

[0026] According to one embodiment, a detection device is provided which is configured to generate a further sensor signal depending on a user interaction, wherein the control unit is configured to control the actuator depending on the (first) sensor signal and the further (second) sensor signal.

[0027] In particular, a redundant system can be set up in which, for example, possible misinterpretations of the first sensor signal are reduced or eliminated.

[0028] According to one embodiment, a user interface and a control unit are provided, wherein the control unit is configured to control the user interface depending on the sensor signal.

[0029] According to one embodiment, the user interface is configured to output an acoustic and / or visual output signal to a user of the household dishwasher, wherein the control unit is configured to control the user interface to output the acoustic and / or visual output signal.

[0030] A light, a display, and / or a speaker can be used as a user interface. The user interface can also be integrated into a device, particularly a smartphone, separate from the household dishwasher. In this case, the household dishwasher includes a communication module, such as a Wi-Fi module, for communication with the user interface. In this case, the control unit controls the communication module based on the sensor signal.

[0031] According to one embodiment, the sensor unit is configured to detect the change in position of the dishware holder and / or the force acting on it along and / or around one, two or three axes.

[0032] It can thus be provided that a multi-dimensional change in position and / or a multi-dimensional force effect is detected by the sensor unit.

[0033] According to one embodiment, the sensor unit is arranged in or on the rinsing container.

[0034] However, it can also be provided that the sensor unit is arranged in or on a door of the household dishwasher.

[0035] According to one embodiment, the sensor unit is configured to detect the change in position of the dishware holder and / or the force effect on it capacitively, inductively, resistively, optically or acoustically.

[0036] In particular, the sensor unit can be designed as an encoder or camera (e.g. CCD chip).

[0037] According to one embodiment, the control unit is configured to detect a user interaction of a user with the household dishwasher and / or an error state of the household dishwasher during a first period of time as a function of the sensor signal and to control the actuator during a second period of time as a function of the sensor signal.

[0038] In particular, parts of the control unit for detecting user interaction or the error state, as well as parts of the control unit for controlling the actuator, can be provided on the same or different hardware (especially a microprocessor). The parts themselves can in turn be implemented as software or hardware. The household dishwasher preferably comprises a control loop comprising the sensor unit, the control unit, and the actuator, wherein the actuator is controlled depending on the sensor signal, even when no user interaction occurs. The sensor signal is used here as feedback for controlling the actuator movement.

[0039] In other words, the sensor unit may already be present in the household dishwasher for other purposes, in particular for monitoring a partially or fully automatic rack movement (also known as ARM). Advantageously, the sensor unit is assigned an additional (dual) function, namely, in particular, the detection of user interaction (e.g., a door opening request).

[0040] According to one embodiment, a control device is provided which is configured to cause the household dishwasher to carry out one or more washing programs, as well as a control unit which is configured to influence the one or more washing programs depending on the sensor signal.

[0041] For example, it can be provided that the sensor unit detects the load status of the dishware holder and that the control unit adapts washing parameters, for example the washing duration, for one or more washing programs based on the determined load status.

[0042] The units mentioned here, in particular the control unit, can be designed as hardware and / or software.

[0043] Further possible implementations of the invention also include combinations of features or embodiments described above or below with respect to the exemplary embodiments not explicitly mentioned. Further advantageous refinements and aspects of the invention are the subject of the dependent claims and the exemplary embodiments of the invention described below. The invention will be explained in more detail below using preferred embodiments with reference to the accompanying figures.

[0044] It shows Fig. 1 is a schematic perspective view of an embodiment of a household dishwasher; Fig. 2 is a section II-II from the Fig. 1 , with the door in its closed state; Fig. 3 the view from the Fig. 2 , with the door in its open state; Fig. 4 a schematic illustration of an embodiment of the electronic control of a household dishwasher; Fig. 5 enlarged view from the Fig. 2 , wherein a coupling device is additionally provided; Fig. 6 the view from the Fig. 3 , whereby a weight acts on the upper dishware holder; Fig. 7 the view from the Fig. 3 , whereby an object prevents the upper dishware holder from being inserted into the washing container; Fig. 8 in a section corresponding to the Fig. 3 a household dishwasher according to another embodiment; and Fig. 9 shows a sensor signal as a function of time.

[0045] In the figures, identical or functionally equivalent elements have been given the same reference numerals unless otherwise stated.

[0046] The Fig. 1 shows a schematic perspective view of an embodiment of a household dishwasher 1. The household dishwasher 1 comprises a washing container 2, which can be closed by a door 3, in particular in a watertight manner. For this purpose, a sealing device (not shown in detail here) can be provided between the door 3 and the washing container 2. The washing container 2 is preferably cuboid-shaped. The washing container 2 can be arranged in a housing of the household dishwasher 1. The washing container 2 and the door 3 can form a washing chamber 4 for washing dishes.

[0047] Door 3 is in the Fig. 1shown in its open position. The door 3 can be closed or opened by pivoting about a pivot axis 5 provided at a lower end of the door 3. With the help of the door 3, a loading opening 6 of the washing container 2 can be closed or opened. The washing container 2 has a base 7, a ceiling 8 arranged opposite the base 7, a rear wall 9 arranged opposite the closed door 3 and two side walls 10, 11 arranged opposite one another. The base 7, the ceiling 8, the rear wall 9 and the side walls 10, 11 can be made, for example, from a stainless steel sheet. Alternatively, the base 7 can, for example, be made from a plastic material.

[0048] The household dishwasher 1 further comprises at least one dishware receptacle 12 to 14. Preferably, several, for example three, dishware receptacles 12 to 14 can be provided, wherein the dishware receptacle 12 can be a lower dishware receptacle or a lower basket, the dishware receptacle 13 can be an upper dishware receptacle or an upper basket, and the dishware receptacle 14 can be a cutlery drawer. Fig. 1 As further shown, the dishware receptacles 12 to 14 are arranged one above the other in the washing container 2. Each dishware receptacle 12 to 14 can be selectively moved into or out of the washing container 2. In particular, each dishware receptacle 12 to 14 can be pushed or moved into the washing container 2 in an insertion direction E (arrow) and pulled or moved out of the washing container 2 in an extension direction A (arrow) opposite to the insertion direction E (arrow).

[0049] The Fig. 2 and 3 each show a section II-II from the Fig. 1. In the Fig. 2 the door 3 of the household dishwasher 1 is in its closed position, in which Fig. 3 shown in its open position.

[0050] The household dishwasher 1 has a device 15 for the automatic rack movement (hereinafter: ARM) of the upper dishware holder 13 into or out of the washing tub 2.

[0051] The device 15 comprises, for example, a sensor unit 16, an actuator 17 and a gear 18. A control unit 19 (see Fig. 4 ) can also be part of the device 15. However, the control unit 19 can also be part of a central control device 20 of the household dishwasher 1.

[0052] The sensor unit 16 is designed to detect a change in position of the upper dishware holder 13. A change in position is understood to mean, in particular, a translational movement of the upper dishware holder 13 in the insertion direction E (inward direction; arrow) and / or in the extension direction A (outward direction; arrow). The sensor unit 16 is preferably an encoder. The sensor unit 16 is connected to the Fig. 4 The sensor unit 16 is connected to the schematically shown control unit 19 for signaling purposes. If the sensor unit 16 detects a change in the position of the upper dishware holder 13, the sensor unit 16 generates a sensor signal S1.

[0053] The actuator 17 is preferably an electric motor and is controlled by the control unit 19. The actuator 17 drives the gear 18. The gear 18 drives the upper dishware holder 13, in particular via a rack (not shown in detail here). This is mounted on the washing tub 2 by means of a telescopic extension 21 and can be moved into or out of the tub. The actuator 17 is configured to either automatically execute or assist (power assistance) an extension and / or retraction movement of the upper dishware holder 13 in the extension direction A (arrow) or in the insertion direction E (arrow).

[0054] The control unit 19 is particularly configured to detect one or more (even different) user interactions depending on the sensor signal S1. The user interaction may be a door opening request, expressed, for example, by the user of the household dishwasher 1 pressing on the door 3. This causes a change in the position of the upper dishware holder 13. The control unit 19 detects a door opening request if the change in the position of the upper dishware holder 13 is, for example, between 1% and 5% of the extension length. Extension length here refers to the maximum length that the upper dishware holder 13 travels during the retraction or extension movement (meaning the distance between the maximum retracted and maximum extended positions).

[0055] The detected door opening request can be implemented by the control unit 19 in various ways: According to a first embodiment, the control unit 19 controls an actuator embodied as a wax motor 23 using a control signal S2. The wax motor 23 unlocks a door lock 24 of the door 3, so that the door 3 opens slightly under the action of a spring (not shown in detail here).

[0056] According to a second embodiment, the control unit 19 controls the actuator 17 by means of the control signal S2 such that the upper dishware holder 13 is pressed against the inside of the door 3. If the force exerted by the upper dishware holder 13 on the inside of the door 3 exceeds a threshold value, the door 3 opens. The upper dishware holder 13 is then extended further in the extension direction A (arrow), and the door 3 is opened further under the influence of the upper dishware holder 13.

[0057] The first and second embodiments can also be combined with each other. Accordingly, it is possible for the door lock 24 to be unlocked first under the influence of the wax motor 23, and then for the door 3 to be opened under the influence of an extension movement of the upper dishware holder 13.

[0058] The user interaction can also be a request to close the door. To do this, the user moves from the position shown in the Fig. 3 In the position shown, the upper dishware holder 13 moves in the insertion direction E (arrow). The resulting change in position is detected by the sensor unit 16. This generates a sensor signal S1, depending on which the control unit 19 detects a door closing request.

[0059] If the door closing request is detected, the control unit 19 controls the actuator 17 in such a way that the upper dishware holder 13 is moved in the insertion direction E (arrow) and thus retracted.

[0060] The upper dishware holder 13 is preferably secured by means of a Fig. 5 shown and designed as a hook 25. The hook 25 is attached to the door 3 and engages in the upper dishware holder 13. The door 3 and the upper dishware holder 13 can be uncoupled by the user when the upper dishware holder 13 is extended - partially or completely depending on the embodiment - and the user opens the door 3 further. This disengages the hook 25 from the upper dishware holder 13. In order to engage the hook 25 back into the upper dishware holder 13, the user closes the door 3 again at least partially, in particular to the extent that the door 3 is brought into contact with the upper dishware holder 13 (or just before).

[0061] The hook 25 pulls the retracting upper dishware holder 13 along with the door 3. This closes the door 3. Once the door 3 is closed, the control unit 19 activates the wax motor 23 to lock the door lock 24.

[0062] The household dishwasher 1 preferably has damping elements 22. The damping elements 22 can, in particular, be attached either to the upper dishware holder 13 or to the inside of the door 3. These serve to dampen the impact of the door 3 on the upper dishware holder 13 (or vice versa), thereby reducing the risk of damage to the upper dishware holder 13 and / or the door 3. The damping elements 22 can, for example, be made of an elastomer.

[0063] In another possible embodiment, the control unit 19 is configured to retract the upper dishware holder 13 into the washing tub 2 automatically or with force assistance, depending on the sensor signal S1, without closing the door 3. This is the case, for example, if the upper dishware holder 13 and the door 3 are not mechanically coupled because the hook 25 is not engaged.

[0064] In order to provide a redundant system that is less prone to errors, a sensor 26 (see Fig. 4 and 5 ) of the door lock 24. This is configured to detect a door opening request. If the sensor 26 detects a door opening request, it generates a sensor signal S3. The control unit 19 then opens the door 3 only if it detects a door opening request based on the sensor signal S1 and the further sensor signal S3.

[0065] The control unit 19 can also be configured to control a user interface depending on the sensor signal S1. In the embodiment according to the Fig. 2 and 3 A light source 27 is arranged on the ceiling 8 of the washing container 2. When the control unit 19 detects a door opening request, the light source 27 is controlled by the control unit 19 using a control signal S4 and is thereby switched on. The light source 27 can then remain switched on for a predetermined time before being switched off. It can also be provided that the light source 27 is switched on during an extension movement of the upper dishware holder 13 and switched off during a retraction movement of the upper dishware holder 13. The light source 27 is in the Fig. 3 shown in the switched-on state, since the upper dishware holder 13 is extended from the washing container 2, and in the Fig. 2shown in the switched off state, since the upper dishware holder 13 is retracted into the washing container 2.

[0066] The control unit 19 can also control another acoustic and / or visual user interface, such as a smartphone. This allows information to be communicated to the user of the household dishwasher 1. For example, the user can learn whether the door 3 is open or closed, or whether the light source 27 is on or off.

[0067] The control unit 19 can also be configured to detect an error condition of the household dishwasher 1. An error condition could be, for example, an overload of the upper dishware holder 13.

[0068] An overload situation is in the Fig. 6shown schematically. The sensor unit 16 detects a force acting on the upper dishware holder 13. The force exerted on the upper dishware holder 13 (and not a change in position) is measured directly, for example, capacitively or resistively using a strain gauge.

[0069] If the weight of a load 28 of the upper dishware holder exceeds a predetermined threshold value, the control unit 19 detects an error condition of the household dishwasher 1 and, for example, activates a warning light 29.

[0070] The control unit 19 can also be configured to adapt a washing program stored on the control unit 20 depending on the sensor signal S1, which is representative of the weight of the load 28. In particular, the amount of water used during washing can be adjusted as a parameter of the washing program based on the detected weight.

[0071] The error condition may also be the case that an object 30 obstructs the retraction movement of the upper dishware holder 13, as described in the Fig. 7is shown. In this case, the sensor unit 16 detects an actual movement pattern of the upper dishware holder 13. This is compared by the control unit 19 with a target movement pattern. The target movement pattern is representative of a retraction movement of the upper dishware holder 13 into the washing tub 2 when it is not blocked by the object 30. If the actual movement pattern and the target movement pattern differ from one another, the control unit 19 detects an error condition of the household dishwasher 1. For example, the control unit 19 then controls the actuator 17 in such a way that the upper dishware holder 13 is stopped. This can prevent possible injuries to people and / or damage to the household dishwasher 1. In this case, too, the warning light 29 can be switched on to inform the user of the household dishwasher 1 about the error condition.

[0072] The comparison of the actual and the target movement pattern can also be used to detect further error conditions, for example a defect in the device 15 of the household dishwasher 1.

[0073] In the embodiment of the Fig. 8 The sensor unit 16 detects a change in the position of the lower dishware holder 12. This can be pivoted out and / or poured in using a device 31 (Lower Rack Elevation, or LRE). The above statements regarding the upper dishware holder 13 apply accordingly.

[0074] The Fig. 9 shows a sensor signal S as a function of time t. During a first time period t 1 , the sensor unit 16 detects a change in the position of the upper dishware holder 13, which is caused by a user interaction. The sensor unit 16 then generates a sensor signal S1, which is Fig. 9shown by a dashed line. From this, the control unit 19 recognizes the door opening request and accordingly controls the actuator 17 to move the upper dishware holder 13. This movement, in turn, is detected by the sensor unit 16 and provided to the control unit 19 (sensor signal S1' in the solid line). The sensor signal S1' is therefore not recognized as user interaction during the second time period t 2 , but is used as feedback to control the actuator movement.

[0075] Although the present invention has been described using exemplary embodiments, it can be modified in many ways. Reference symbols used
