EMZ-HANAUER GMBH & CO. KGAA

Embodiments of the invention provide a door opener for an electrical appliance of household equipment. The door opener comprises an electric motor and a pusher drivable by means of the electric motor for pressing co-operation with the door of the electrical appliance. A power transmission mechanism is provided between the electric motor and the pusher, which is capable of ensuring a variable effective velocity of the pusher at the same rotational frequency of the electric motor. Certain embodiments provide for a multi-stage rack and pinion gear for this purpose, which is formed by a gear rim and a toothed rack, which can transmit the driving force of the electric motor to the pusher via various gear pairings that can be brought alternately into meshing engagement with one another.

The invention relates to a domestic cleaning machine, in particular a built-in domestic cleaning machine, comprising a cleaning machine body and a cleaning machine door connected thereto for closing the domestic cleaning machine, wherein a main tub for holding objects to be cleaned and flushing liquid is provided in the cleaning machine body, and wherein a sump and a salt compartment are arranged below a bottom of the main tub, and wherein a detergent compartment, which is designed to hold detergent, is additionally provided, and wherein a water cycle is provided for supplying water for a wash cycle of the domestic cleaning machine. According to the invention, it is provided that the detergent compartment is also arranged below the bottom of the main tub.

The invention relates to a filtration device, in particular for the filtration of microplastics for a water-bearing household appliance, wherein the filtration device comprises a housing in which a filter element is arranged, wherein the filter element is designed in such a way that it encloses an inner cavity which is fluidically connected to a supply line element, wherein a first drain element is arranged along the height axis Z above the filter element, wherein a second drain element is arranged along the height axis Z below the filter element.

A door lock mechanism for domestic appliances with a guide element which can be engaged behind by at least one pivotable, resiliently mounted lever arm for locking a door of the domestic appliance is disclosed. This door lock mechanism is characterized by a displaceably mounted locking element which, depending on its movement position, can block or release the at least one lever arm in a pivoting position.

Device for detecting substance groups in a fluid within a household appliance, comprising an emission apparatus that emits a first electromagnetic radiation, characterized by an emission spectrum, into a test volume present with the fluid, further comprising a first measuring apparatus that detects a first spectrum of a second electromagnetic radiation led out of the test volume present with the fluid, further comprising an evaluation apparatus that is provided and designed to evaluate the first spectrum, whereby substance groups can be identified by using reference spectra, with the emission spectrum comprising a wavelength range of visible light and infrared radiation.

A sensor apparatus for a water-using household appliance for detecting at least one process parameter includes a housing in which at least one circuit board, a first sensor arrangement and a second sensor arrangement are arranged. The first sensor arrangement is arranged on the at least one circuit board. The second sensor arrangement is spaced apart from the first sensor arrangement along a height axis. A holder element is arranged on the at least one circuit board, on or in which at least one pin-like contact element is arranged. The at least one pin-like contact element is intended and suitable for providing an electrical connection between the second sensor arrangement and the at least one circuit board.

An ice-making apparatus for a household appliance includes a housing and at least one mould element which is suitable and intended for moulding a piece of ice. At least one mould holding device is provided, in which the at least one mould element is arranged. The at least one mould holding device is pivotable about a first pivot axis relative to the housing from a first position into an ejection position. A pivoting into the ejection position actuates an ejection mechanism acting on the at least one mould element in such a way that in the ejection position the piece of ice emerges from the mould element.

A water-carrying household appliance ( 1 ) includes a process compartment ( 2 ) into which a process liquid ( 3 ) can be introduced and a sensor device ( 4 ). The sensor device ( 4 ) has at least one radiation source device ( 5 ) and at least one detector device ( 8 ). The sensor device ( 4 ) in each case determines a transmission value along at least two radiation paths through the process liquid ( 3 ). The two radiation paths run spatially separated from one another at least within the process liquid ( 3 ). A turbidity value of the process liquid ( 3 ) is determined from a comparison of the at least two transmission values.

A door latch includes a gripper adjustable between a gripping state and a release state, which gripper, in the gripping state, is able to grip a closing member for holding the door closed which moves relatively closer to the gripper in a closing direction as a door of the domestic appliance is closed, and, in the release state, frees the closing member for opening the door, wherein, when the door is closed, the gripping state of the gripper is released by a relative releasing movement of the closing member carried out in the closing direction; and an electrically controllable displacement mechanism for displacing the gripper, under electrical control, from a retracted position into an advanced position against a restoring spring force, which advanced position, when the closing member is gripped, corresponds to a state in which the door is closed to a lesser degree than in the retracted position.

The invention relates to an ice maker, in particular for a household appliance, comprising at least one moulding element which is suitable and intended for moulding an ice piece, wherein the at least one moulding element is fluidically connected to a liquid supply device, wherein at least one cooling supply device is provided, which supplies a cooled fluid to the at least one moulding element in such a way that it impinges on an upper area of the at least one moulding element along the height axis, wherein the liquid supply device comprises at least one liquid reservoir which is arranged along the height axis below the at least one moulding element.
