Figs. 2A-2F are perspective views of a household appliance with a radar sensor which is designed to detect a hand movement of the user; and FIG. 3 is a schematic representation of a method for controlling a

Operating parameters of a household appliance.

Fig. 1 shows a schematic view of a household appliance 100, such as e.g. a trained as a washing machine laundry care device. The laundry care appliance comprises an induction bowl 101, and into which detergent or other laundry-care substances can be introduced. The laundry care appliance comprises a device door 103 for loading the laundry care appliance with laundry. The appliance door 103 closes a device opening 105 on a front side 107 of the laundry care appliance. The laundry care apparatus further comprises a display element 109 for displaying a

Object on. The display element 109 comprises a display, in particular an LCD display, LED display or a TFT display.

The laundry care device further comprises a sensor 1 1 1, in particular a radar sensor 1 1 1, which is formed, hand movements of a user of the

To detect laundry care device to the user in the laundry care process

support and provide him with an intuitive input tool. The sensor 1 1 1, in particular radar sensor 1 1 1, is at the front 107 of the

Laundry care device arranged, and is designed to emit radar radiation 1 12.

In this case, however, it may be necessary (eg due to signal resolution) to optimize the position of the sensor 11, or to use one or more further sensors 11. Likewise, the signal range of the sensor 1 1 1 can be increased by radar wave-transmissive materials on the housing of the front side 107, by reflectors or locally smaller wall thicknesses, for example in the control panel. In order to realize flexible or more complex, situational operator inputs and operator outputs, the laundry care device has the display element 109, which is preferably designed as a large full-color display in order to signal an optical feedback.

The sensor 1 1 1 physically detects the movement of the user's hand, with a controller locally available in the laundry machine, or available as a cloud application remotely in the laundry machine, using the appropriate algorithms of the signals, various operations and process actions, as in the introduction of laundry in a laundry drum of the

Detecting laundry care device.

A software solution for learning new gestures after the initial programming is optionally available to the user so that a learning system can be provided.

There are several preferred variations on how gesture detection can be used to improve user interaction with the laundry care device. Specific applications include e.g. the ability to perform complex control functions through a more intuitive, i. To replace simpler, and flexibly teachable control, extending the gesture detection from the control panel to the entire device and performing user actions on or before the laundry care device. In addition, the user actions include an Einlerne option for new gestures, a user identification, as well as individual reactions of the user, as well as a detection of the laundry movement, as well as easier operation of the machine by people with disabilities. Furthermore, further functions include the non-contact operation of the machine without being adversely affected by soiling and / or attaching

Moisture on the control panel, the detection of children or children's hands and locking the device, as well as the recognition of the geometry or outlines of

held laundry items for identification and selection of the appropriate

Laundry care program, or the detection and differentiation of regional and / or country-specific gestures, and the unlocking of the laundry care device by trained gestures, or the detection of the environment around the machine for evaluation of the installation or for spin / vibration detection / characterization.

Figures 2A to 2F show perspective views of a laundry care device with a radar sensor 1 1 1, which is designed to detect a hand movement 1 17 of the user.

In the laundry care device, a display element 109 with a graphical

User interface 1 13 used on which, or on which objects 1 15 are displayed, the objects 1 15 typical for the laundry care device

Include controls. The object 1 15 shown in Fig. 2A comprises a rotatable knob 15-1. The object 1 15 shown in FIG. 2B includes a

Slider 1 15-2. The object 1 15 shown in FIG. 2C or 2D comprises a button 1 15-3, in particular button 1 15-3.

A sensor 1 1 1, in particular a radar sensor 1 1 1, in this case can detect a hand movement 1 17 of a user of the laundry care device. A controller is configured to change an object parameter of the respective object 1 15 in response to the detected hand movement 17 of the user, so that an optical feedback is provided to the user in which the object parameters of the object 1 15 on the display element 109 are changed.

In addition, further acoustic feedback is possible through a signal unit or an optical signal (such as status lights, LED display, etc.). Sequential operations may be displayed on the same area of the display element 109, e.g. Wash program selection, wash temperature selection, or other options.

In a learning mode, alternative gestures can also be taught to the machine on a personal basis, eg for handicapped persons without index finger, or only with left arm. In a so-called "laundry care guide" mode, the radar sensor 1 1 1 can be switched on to detect the user movements in order to support customers during the entire process of the laundry care journey on the device. For this the user actions are analyzed, eg opening / closing of the detergent drawer, Loading detergent, inserting or removing laundry, opening the door, - or closing, program selection, and checking for malfunctions.

The machine may then provide appropriate user-dependent recommendations (e.g., via display, projection, or voice output) for the next step (e.g.

Fill detergent, or forgotten, laundry in half load program stuffed too much in the drum, etc.).

By the radar sensor 1 1 1 with all interactions of the user can be detected and evaluated with the laundry care device, the structure and the cost of a control panel can be drastically reduced. Here are no

Single elements needed, a simpler structure of the control electronics or complex controls are ensured. In addition, gaps and scratches on the device, in which dirt can get into the component design could be avoided, whereby an easier cleaning of the smooth control panel can be ensured.

An advantage of the gesture control is also that the controls are not through

Moisture, grease, detergents or other contaminants are impaired in their function. Likewise, in the case of adaptive systems, operating errors can be avoided, such as e.g. Swipe instead of tapping on a button, which allows the user to re-learn their own gestures at any time.

A learning gestures control can be designed software so that the user always has the ability to control the device with the gestures that he can clearly perform. To do this, the user interface must be equipped with an easy-to-learn controller. Even temporary restrictions, such as carrying a full laundry basket, no longer have to be an obstacle to the use of the machine. The user could also adjust other body movements, eg to open the door at a certain distance. Preferably, the manufacturer offers a complete set of pre-set meaningful gestures from which the user can select for him or her. Here, cultural differences in operator actions and possible tax gestures can and must be taken into account. The capture of gestures can help with corresponding learning algorithms are also used for user recognition.

This allows a security function to be implemented: only authorized persons can operate the device, which ensures an effective parental control.

A new door opening gesture can be designed so that opening the door allows a more appealing, elegant operation.
