Description

[0001] The present invention relates to a dishwasher, such as a household dishwasher, and to a method for operating a dishwasher.

[0002] A household dishwasher typically includes a wash container that can be closed by a door and has a number of compartments for holding items to be washed, and a control device for carrying out a wash program from a plurality of wash programs for washing items.

[0003] Document DE 10 2017 218 493 A1 shows a household dishwasher with a housing, a door pivotably connected to the housing, a rope connected to the door, a pulley in contact with the rope and a motor which is designed to drive the pulley to move the rope in such a way as to cause a pivoting movement of the door.

[0004] Furthermore, document DE 196 51 346 A1 discloses a dishwasher with a control unit that allows complete adaptation of the program sequence to the most varied degrees of soiling of the dishes to be cleaned. The program sequence can be preselected on the control unit by means of at least one parameter that is essentially continuously adjustable, necessary for the washing process, and influenced by it.

[0005] DE 10 2018 211 587 A1 discloses a method for controlling a household appliance in which the state of the household appliance and the direction of view of a user are recorded and evaluated.

[0006] DE 10 2015 222 580 A1 discloses a water-bearing household appliance with a pivoting door and a detector for detecting the presence of a living being in a specific area in front of the household appliance, wherein a control is provided which is designed to prevent the door from being opened depending on the presence of a living being detected by the detector in the specific area.

[0007] DE 10 2018 221 163 A1 discloses a water-bearing household appliance with a control device for carrying out a plurality of treatment programs depending on an input from a user.

[0008] A conventional household dishwasher has a control panel or control module, preferably located on the dishwasher door, which is used to input user commands for operating the dishwasher. For example, the user can select a wash program from a number of predefined wash programs.

[0009] Furthermore, it is known to operate household dishwashers using an app installed on a mobile device, such as a smartphone or tablet.

[0010] However, all these conventional solutions have the disadvantage that the user has to use their hands to operate the dishwasher, even though they may be full of items to be cleaned before loading the dishwasher.

[0011] Furthermore, the document US 2019 / 0265787 A1 describes methods and systems for selecting and controlling an object using eye tracking.

[0012] Against this background, one object of the present invention is to further improve the operation of a dishwasher.

[0013] According to a first aspect, a dishwasher, in particular a household dishwasher, is proposed with a door pivotable about a pivot axis, a wash container closable by the door with a number of dishware holders for receiving dishware, a control device for carrying out a wash program from a plurality N1 of wash programs, an eye-tracking module arranged on the door for providing eye-tracking data from an eye-tracking of eye movements of a user and a detection unit for determining a specific user input for operating the dishwasher depending on the provided eye-tracking data.

[0014] The proposed eye-tracking module and detection unit allow the user to input commands to operate the dishwasher via eye movements. This enables the user to operate the dishwasher even when their hands are full of dishes, dirty, or when voice input is unusable, for example, due to high ambient noise.

[0015] Overall, the eye-tracking module and the detection unit enable contactless operation of the dishwasher in many applications where other input methods, such as haptics or voice control, are not possible or only possible to a limited extent. This contactless operation or control also eliminates the need for conventional control elements such as touch membranes, coupling elements, or mechanical buttons. This not only improves the usability of the dishwasher but also saves costs.

[0016] In this context, the term "user's eye movements" includes, in particular, a specific view of the dishwasher or a specific direction of view of the dishwasher, especially over a predetermined period of time.

[0017] The control device can be implemented in hardware and / or software. The control device is typically integrated into the dishwasher. Alternatively, it can be located outside the dishwasher. In a hardware implementation, the control device can be, for example, a computer or a microprocessor. In a software implementation, the control device can be a computer program, a function, a routine, part of program code, or an executable object.

[0018] The control device is sometimes configured to execute a wash program from a plurality of wash programs to rinse the items being washed. A wash program comprises, for example, various sub-program steps, such as pre-rinsing, cleaning, rinsing, and / or drying. Different wash programs differ, for example, in the sequence and / or type of sub-program steps, as well as in various operating parameters, such as the duration and / or wash water temperature of one or more sub-program steps.

[0019] Dishes and other items for washing in a household dishwasher are arranged in the wash chamber, particularly on one or more dish racks. These items include, in particular, various dishes, cutlery, and / or utensils used for preparing, storing, and / or eating food. Examples include plates, pots, cups, knives, glasses, and the like.

[0020] The number of dishwashing compartments includes, in particular, a lower basket, an upper basket and / or a cutlery drawer.

[0021] According to one embodiment, the control device is configured to select one of the number of washing programs based on the determined user input and to execute the selected washing program to wash the items arranged in the washing container, in particular to execute it automatically.

[0022] The wash program selected by the user is then preferably displayed on a screen on the dishwasher, for example, on the control panel. This provides the user with appropriate feedback on their input.

[0023] In the present embodiment, the user selects a specific washing program from the washing programs of the dishwasher by means of his eye movements or his gaze or direction of view at the dishwasher, and the selected washing program is automatically executed by the control device.

[0024] According to a further embodiment, for a number N3 of N1 wash programs, with N3 ≤ N1, a number N3 of graphic symbols are arranged on the door, each symbol corresponding to one of the N1 wash programs. The detection unit is configured to interpret a user's gaze on a specific symbol for a duration exceeding a certain threshold, based on the provided eye-tracking data, as a user input to select the wash program associated with that symbol. The control device is then configured to automatically execute the selected wash program to wash the items in the wash tub.

[0025] This means that for all or a subset of the dishwasher's N1 wash programs, a corresponding graphic symbol is positioned on the door so that the user can focus their gaze on it. If the user looks at a particular graphic symbol for more than two seconds, for example, the detection unit interprets this as a user input to select the wash program associated with that symbol. The control unit then automatically executes the selected wash program.

[0026] According to another embodiment, a pivoting device is provided for automatically pivoting the door. The detection unit is configured to derive an indicative control command for pivoting the door from the provided eye-tracking data and to control the pivoting device for pivoting the door using the derived control command.

[0027] For example, if the user approaches the dishwasher with their hands full of dishes, their hands are not free to operate the dishwasher. However, in this case, they can use their eye movements or a specific gaze towards the dishwasher, particularly towards a graphic symbol on the door indicating that it should open, to automatically open the door. This significantly simplifies the user's operation of the dishwasher.

[0028] According to the invention, a sensor for detecting a door opening angle and a tracking unit are provided, which is configured to track a detection angle of the eye-tracking module depending on the detected door opening angle.

[0029] In this embodiment, the detection angle of the eye-tracking module is automatically adjusted depending on the detected door opening angle. Consequently, a cost-effective eye-tracking module with a narrow detection angle can be used, since the tracking is performed automatically by the proposed tracking unit.

[0030] According to another embodiment, the control device integrates the detection unit. In this embodiment, the detection unit is implemented in the control device as part of the control device, for example as software.

[0031] According to another embodiment, the dishwasher is a fully integrated, fully automatic dishwasher. The application of the present operating concept based on eye tracking is particularly advantageous in a fully integrated dishwasher, since the design of the fully integrated dishwasher means that the user always looks perpendicularly at the top edge or front of the door, and thus at the eye-tracking module, when the door is open. This provides ideal conditions for the camera or cameras of the eye-tracking module. Consequently, a high-resolution camera is not required, and the camera's field of view can be quite small.

[0032] According to another embodiment, the eye-tracking module is arranged at the top edge of the door. The top edge of the door can also be referred to as the front face.

[0033] According to another embodiment, the dishwasher is a fully integrated automatic dishwasher and the eye-tracking module is located at the top edge of the door of the automatic dishwasher.

[0034] This embodiment with the fully integrated dishwasher and the arrangement of the eye-tracking module at the top edge of the door has the particular advantage that a cost-effective eye-tracking module with a comparatively narrow detection angle can be used, since the user practically always looks at the top edge of the door when the door of the fully integrated dishwasher is open, and thus his eye movements can be easily recorded by the eye-tracking module.

[0035] According to another embodiment, the eye-tracking module comprises a number N2 of cameras, with N2 ≥ 1, in particular with N2 ≥ 2, which are arranged at the top edge of the door. The respective camera is, in particular, a digital camera, for example with a CCD sensor (CCD: Charged Coupled Device). The camera captures, for example, a photograph, a sequence of photographs, and / or a video.

[0036] According to another embodiment, the eye-tracking module is configured to select a subset of the N2 cameras, with N2 ≥ 2, to provide the eye-tracking data for the investigation unit depending on the detected door opening angle of the door.

[0037] Depending on the current door opening angle, the camera or cameras from the N2 cameras that currently offer the optimal conditions for capturing the user's eye movements or gaze direction are selected.

[0038] According to another embodiment, the eye-tracking module is arranged on a longitudinal center axis of the door. The longitudinal center axis of the door extends, in particular, longitudinally through the center of gravity of the door. Specifically, the eye-tracking module is thus arranged centrally on the front face of the door.

[0039] According to another embodiment, a proximity sensor is provided which is designed to detect when the user approaches the dishwasher and to activate the eye-tracking module when a proximity is detected.

[0040] This design is particularly energy-efficient, as the eye-tracking module is only activated when the user's approach is detected and is otherwise deactivated.

[0041] According to another embodiment, the detection unit is further equipped to recognize an obstacle located in front of the door from image data recorded by the eye-tracking module and to stop the door from pivoting when an obstacle is detected.

[0042] An example of such an obstacle could be a small child. Therefore, if a small child is in front of the door and this is detected by a camera in the eye-tracking module, the automatic opening of the door will be prevented.

[0043] According to another embodiment, a voice input unit is provided which is designed to capture voice commands from the user for operating the dishwasher.

[0044] The voice input unit can, for example, be integrated into the outer casing of the dishwasher and linked to the dishwasher's control unit. Alternatively, the voice input unit can also be implemented on the user's mobile device, such as a smartphone or tablet.

[0045] According to another embodiment, a gesture input unit is provided which is designed to capture gesture inputs from the user for operating the dishwasher.

[0046] The gesture input unit can, for example, be integrated into the outer casing of the dishwasher and linked to the dishwasher's control unit. Alternatively, the gesture input unit can also be implemented on the user's mobile device.

[0047] The voice input unit and / or the gesture input unit are, for example, designed as components of an app that can be installed on the mobile device. The mobile device is, for example, a smartphone, a tablet, or a tablet computer.

[0048] According to a second aspect, a system is proposed which includes a dishwasher according to the first aspect or one of the embodiments of the first aspect, as well as a mobile terminal.

[0049] As stated above, the mobile device is preferably a smartphone, a tablet or a tablet computer that integrates the voice input unit and / or the gesture input unit.

[0050] The app can also be referred to as an application, application software, or application program. In particular, the app can be structured as a program, a computer program, software, a computer program product, a function, a routine, a part of program code, or an executable object.

[0051] In particular, the dishwasher includes a communication unit that can be connected to a mobile device, and thus to the app installed on the external device, via a network. This network includes, in particular, a mobile network, a Wi-Fi network, and / or another wireless or wired data network.

[0052] According to a third aspect, a method for operating a dishwasher, in particular a household dishwasher, is proposed, which has a door pivotable about a pivot axis, a wash tub closable by the door with a number of dish holders for receiving dishes, and a control device for carrying out a wash program from a plurality N1 of wash programs. The method comprises the following steps: Providing eye-tracking data by means of an eye-tracking module located at the door, from an eye-tracking of a user's eye movements, and Determining a specific user input for operating the dishwasher based on the provided eye-tracking data. Detecting the door opening angle (3) using a sensor for detecting a door opening angle and Tracking of a detection angle of the eye-tracking module (110) by means of a tracking unit depending on the detected door opening angle.

[0053] The embodiments and features described for the proposed dishwasher apply accordingly to the proposed method.

[0054] According to a fourth aspect, a computer program product is proposed which, on a program-controlled device, initiates the execution of the procedure described above.

[0055] A computer program product, such as a computer program tool, can be provided or delivered from a server on a network, for example, as a storage medium such as a memory card, USB stick, CD-ROM, DVD, or as a downloadable file. This can be done, for example, in a wireless communication network by transmitting the corresponding file containing the computer program product or tool.

[0056] Other possible implementations of the invention also include combinations of features or embodiments described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. In such cases, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the invention.
