The invention proposes a dishwasher comprising a working chamber, comprising at least one spray arm which is arranged in a rotatable manner in the working chamber, and comprising a metering apparatus for supplying and metering a substance, such as detergent, rinse aid etc., into the working chamber, which metering apparatus is designed as an insert part comprising a housing for insertion into a recess in an inner wall of the working chamber, for example in the door of the working chamber, and comprising a sensor unit for identifying a spray arm movement in the working chamber of the dishwasher, which sensor unit is arranged at least partially in a housing of the metering apparatus, wherein the sensor unit 11 comprises at least one infrared transmitter 12 and/or one infrared receiver 13.

A washing-agent dispenser for machines for washing, in particular dishwashers, comprises: a dispenser body (11) with at least one receptacle FIG. 14 (12, 12a) for containing a washing agent; at least one hatch (20) having a hatch body (21) mounted in a guided way relative to the dispenser body (11) for being slidable between a position of closing and a position of opening of the at least one receptacle (12, 12a), the hatch body (21) having two longitudinal sides (21b, 21c) generally parallel to one another and with respect to a direction of displacement of the hatch body (21) between the position of opening and the position of closing; and a guide arrangement (25-27, 30a-30b, 31a-31b) between the dispenser body (11) and the hatch body (21), for guiding displacement of the hatch body (21) between the position of opening and the position of closing. The guide arrangement (25-27, 30a-30b, 31a-31b) comprises at least one movable guide element (25), in a position corresponding to a respective longitudinal side (21b, 21c) of the hatch body (21), the movable guide element (25) being constrained to the dispenser body (11) for being slidable between an inoperative position and an operative position.

A washing-agent dispenser designed for being mounted at a through opening (A) of a tub wall (5) of a dishwasher comprises:—a dispenser body (11), having a rear part (11′) and a front part (11″); —a perimetral gasket (30) mounted in a corresponding seat (S) of the dispenser body (11) and prearranged for exerting a sealing action with respect to a mounting side (5a) of the tub wall (5); —a frame (40) having a substantially annular shape, defining a central passage (B) through which the rear part (11′) of the dispenser body (11) is insertable. The frame (40) has at least one of the following:—first coupling means (41), which can be coupled to corresponding second coupling means (16) provided in the dispenser body (11), the first coupling means (41) and the second coupling means (16) being configured for fixing of the dispenser body (11) at the through opening (A) of the tub wall (5), in a condition of at least partial compression of the perimetral gasket (30) for exerting thereby a sealing action between the dispenser body (11) and the mounting side (5a) of the tub wall (5); and—reinforcement means (42, 43), prearranged for countering possible deformation or yielding of the tub wall (5) at least in an area thereof that circumscribes the corresponding through opening (A).

A dishwasher washing agent dispenser includes (a) a dispenser body, configured to be set partially into an opening of an inner side of a dishwasher door and the dispenser body has a receptacle for containing a washing agent, (b) a dispenser door mounted in a guided way with respect to the dispenser body, for being slidable between positions of closing and opening of the receptacle, the open position allowing dispensing of the washing agent from the receptacle, (c) guides between the dispenser body and the dispenser door, for guiding displacement of the dispenser door between the positions of closing and opening in such a way that, when the dispenser door is open, a portion of the dispenser door projects from the dispenser body, in a substantially cantilever fashion, and (d) a supporting element extending in length downwards from the dispenser door and configured to counter bending of the portion of the dispenser door that projects from the dispenser body when the dispenser door is in the open position.

A cover assembly for mounting in a domestic dishwasher, for example, is proposed. The cover assembly includes a pivoting cover which is mounted on a support component and is to close an opening, wherein the pivoting cover has a cover part and a closure part which is movable relative to the cover part. The cover part has sealing faces which, on closing of the pivoting cover, come into sealing contact with sealing counter-faces encircling the opening. There are formed on the closure part engagement formations which, in a closed pivot position of the pivoting cover, can be brought into and out of holding-closed engagement with engagement counter-formations by relative movement between the closure part and the support component. The cover part is mounted on the closure part and is supported via the closure part on the support component.

A dishwasher includes an image-based detergent sensor that in some instances is configured to sense a type of detergent for use in optimizing a wash cycle based upon the type of detergent, and that in some instances is configured to direct one or more controllable sprayers to facilitate dissolution or mixing of detergent into a wash fluid during a wash cycle.

Example embodiments provide a dishwasher comprising a tub; a door configured for selectively sealing a forward access opening of the tub; a detergent dispenser located at an inner surface of the door; a spray arm mounted within the tub such that the spray arm is adjustable between a first height and a second height, the spray arm comprising a spray detergent nozzle; and a circulation pump configured to supply washing liquid to the spray arm. The dishwasher is characterized in that the spray arm is configured to emit a fan-shaped jet from the spray detergent nozzle when the washing liquid is supplied to the spray arm and the spray arm is configured to emit the fan-shaped jet that is incident upon the detergent dispenser both when the spray arm is positioned at the first height and when the spray arm is positioned at the second height.
