ELECTRICAL HOUSEHOLD APPLIANCE WITH USER INTERFACE Russian patent published in 2023 - IPC D06F35/00 

FIELD: household appliances.

SUBSTANCE: electrical household appliance (1) contains case (2) with outer wall (3) forming outer surface (4), processing site (5) made in case (2) or on it with the possibility of reception or maintenance of household items in processing position (6), processing device (7) located inside case (2), processing detector (8) made with the possibility of determination of a value of a processing parameter, electronic control system (10) having a signal connection to processing device (7) and processing detector (8) and made with the possibility of control of processing device (7), depending on a processing program and depending on a value read by processing sensor (8), user interface (11) having a signal connection to electronic control system (10). In this case, user interface (11) contains at least one video projector (14) installed on outer wall (3) of electrical household appliance (1) and made with the possibility of visualization of parameters of the processing program by means of light projection on display area (15) of outer surface (4) of case (2), and at least one command input sensor (16) intended for detection of movement of the user’s hand in display area (15) and for generation of a corresponding signal of hand movement. At the same time, electronic control system (10) processes the hand movement signal and generates a user command signal, sets parameters of the processing program, depending on the generated user command signal, and controls visualization, using video projector (14), depending on the generated user command signal.

EFFECT: creation of an electrical household appliance with a user interface having such properties, which allow for its easy adaptation to electrical household appliances with irregular surfaces, for example, in the presence of moving parts (hatch, door, tray for detergent), and/or with non-flat parts, and such an interface is easily used and can be transferred from one case to another.
