Abstract: A sensor device to measure a force or pressure in a washing handling apparatus includes a light source, a light receiver, a light-reflecting surface that reflects light emitted by the light source toward the light receiver, and one or more spring elements that biases the light-reflecting surface into a predefined initial position with respect to the light source and the light receiver where the light-reflecting surface is disposed to be displaceable with respect to the light source and the light receiver in response to application of an external force or pressure against a resetting force of the one or more spring elements.

Abstract: The invention relates to an electrical household appliance, namely a refrigeration and/or freezer device or a stove, comprising at least one luminous plate (24) illuminating an interior of the appliance, and a light source device (30) feeding light into at least one narrow side of the luminous plate. According to the invention, the light source device includes at least one light-emitting diode (32) and a lens optics, which collects at least a major portion of the light emitted by the light-emitting diode, directing the light to at least one narrow side of the luminous plate.

Abstract: An ice-making device for a refrigerator or freezer comprises: an ice-making tray having an upper side, a lower side, a longitudinal direction and a transverse direction of said tray, wherein said ice-making tray is mounted so as to be rotatable about a first axis of rotation which is parallel to the longitudinal direction of the tray; a collecting container arranged underneath the ice-making tray for catching ice which falls out of said ice-making tray when the latter is in an emptying rotational position; a wall structure which, when the ice-making tray is in an ice-making rotational position, delimits a first air duct which runs underneath said ice-making tray and is open towards the underside of said tray, wherein said first air duct runs in the longitudinal direction of the tray and extends over substantially the entire length of the ice-making tray, wherein the wall structure has at least one wall element which, when the ice-making tray is in the ice-making rotational position, projects into a falling tr

Abstract: A device to capture the relative position of a component (14) of which the position can change relative to a reference component (12) of a washing handling device (10), in particular a washing machine or drier, includes at least one light source (34, 38, 42), at least one light receiver (36, 40, 44), a light-reflecting surface (50, 52), which reflects light which the light source (34, 38, 42) emits to the light receiver (36, 40, 44). The device is designed to capture the present relative position of the changeable-position component (14) relative to the reference component (12), according to the reflected light which the light receiver (36, 40, 44) captures.

Abstract: An optical sensor for use in a washing machine or dishwasher comprises a housing, a light-emitting element, a light-receiving element and a light-conducting structure, which is made from a transparent material, having a light entry point, a first reflection surface, a second reflection surface and a light exit point. A light measurement path runs from the light-emitting element, via the light entry point, the first reflection surface, the second reflection surface and the light exit point, to the light-receiving element wherein the light undergoes total reflection on the first reflection surface and on the second reflection surface and where a light beam that runs from the first reflection surface to the second reflection surface has a cross-sectional area of not less than 0.9 mm2.

Abstract: An optical sensor for use in a washing machine or dishwasher comprises a housing, a light-emitting element, a light-receiving element and a light-conducting structure, which is made from a transparent material, having a light entry point, a first reflection surface, a second reflection surface and a light exit point. The light-emitting element, the light-receiving element and the light-conducting structure define a light measurement path that runs, in this sequence, from the light-emitting element, via the light entry point, the first reflection surface, the second reflection surface and the light exit point, to the light-receiving element. In this case, on a section located between the first and the second reflection surface, the light measurement path runs outside the housing. The light that reaches the light-receiving element, along the light measurement path, from the light-emitting element undergoes total reflection on the first reflection surface and on the second reflection surface.
