According to the invention, this is achieved in that at least one inlet opening (17) in an interior (22) of the metering apparatus (9) is arranged at least partially in the jet (23) of water/liquid from a spray nozzle (24) of the spray arm (5, 6) during the rotation of the spray arm (5, 6), wherein the sensor unit (27, 28) is arranged at least partially in the/on the interior (22) and/or on a wall of the interior (22).

The invention proposes a dishwasher comprising a working chamber (2), comprising at least one spray arm (5, 6) which is arranged in a rotatable manner in the working chamber (2), and comprising a metering apparatus (9) for supplying and metering a substance, such as detergent, rinse aid etc., into the working chamber (2), wherein the metering apparatus (2) is designed as an insert part (2) comprising a housing (20, 21) for insertion into a recess in an inner wall (7) of the working chamber (2), for example in the door (7) of the working chamber (2), and comprising a sensor unit (27, 28) for identifying a spray arm movement in the working chamber (2) of the dishwasher, which sensor unit is arranged at least partially in a housing (20, 21) of the metering apparatus (9), wherein the dishwasher has improved program control. According to the invention, this is achieved in that the sensor unit (27, 28) comprises at least one pressure sensor (27, 28) for detecting a water/liquid pressure.

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.

The present invention relates to a dishwasher, especially a domestic dishwasher, comprising a body, a washing chamber provided in the body wherein the washing is realized, at least one rack which is located in the washing chamber for loading dishes to be washed and at least one spray arm which rotates around itself and provides water into the washing chamber for washing the dishes. The dishwasher, especially the domestic dishwasher, comprises furthermore a checking mechanism which is configured to translate the sliding movement of the at least one rack into rotation of the at least one spray arm.

Provided herein are a spray arm assembly and associated dishwasher. The spray arm assembly may include a spray arm and a satellite arm. The spray arm may have a body defining an inlet opening and an outlet opening spaced along the body, and the body may receive washing fluid at the inlet opening and direct at least a portion of the washing fluid to an outlet opening. The body may further define one or more fluid supply channels extending between and fluidly communicating the inlet opening and the outlet opening. The satellite arm may be rotatably coupled to the spray arm at the outlet opening, and a portion of the one or more fluid supply channels may extend past the outlet opening to direct at least a portion of the washing fluid past the outlet opening and back towards the inlet opening before entering the outlet opening.

A household dishwasher includes a washing container receiving a dishwasher load, a spray arm for applying washing liquor and/or fresh water to the dishwasher load, a drive system for actively driving the spray arm, and an overload protection mechanism configured to move autonomously from a coupling position, in which power is transmitted between the drive system and the spray arm, into a decoupling position, in which the power transmission between the drive system and the spray arm is interrupted, when the spray arm becomes blocked.

Dishwashing machine comprising: a controller; a spray arm assembly comprising a spray arm having one or more spray holes for spraying a washing load with water, and a pipe for delivering water to the spray arm; a pump for pumping water through the pipe and to the spray arm; the pipe being constructed and arranged to at least partially restrict flow of water from the pump to at least a part of the spray arm dependent on spray arm orientation relative to the pipe, a power consumption of the pump thereby being dependent at least in part on the spray arm orientation relative to the pipe; and the controller being configured to monitor the power consumption of the pump in order to determine rotational information of the spray arm.

The present disclosure relates to a dishwasher. The dishwasher according to an embodiment comprises: a tub having a washing room, in which an object to be washed is accommodated, formed therein; a nozzle which is arranged in the washing room and sprays washing water to the object to be washed, and includes a magnetic body at one end thereof; a coil which his formed to surround a region corresponding to a movable range of the nozzle, and through which an electric current flows according to the rotation of the nozzle; and a controller which controls an operation of the nozzle according to an operation command, and determines an operating status of the nozzle on the basis of a value of the voltage generated in the coil.

A dishwasher may include a spray arm arrangement and a washing chamber. The spray arm arrangement may include a spray arm arranged to rotate around a first axis of rotation within said washing chamber. The spray arm may be provided with one or more spray nozzles arranged to spray washing liquid into said washing chamber. The dishwasher may also include a mechanical switch for detecting an angular position of said spray arm. The spray arm arrangement may further include an activating device arranged to rotate with said spray arm, which activating device may include at least one activating structure arranged to cyclically activate said mechanical switch during rotation of said spray arm.

A household dishwasher includes a washing container holding a dishwasher load, and a container holding an operating material and arranged outside the washing container and accessible via an opening in an interior of the washing container when a door of the household dishwasher is open. A spray arm applies washing liquor to the dishwasher load and is actively driven by a drive entity. A detection entity is operably connected to a drive element of the drive entity for detecting an angular position of the drive element. A control device determines an angular position of the spray arm as a function of the detected angular position of the drive element and, as a function of the determined angular position of the spray arm, activates the drive entity to stop the spray arm within a predefined angular range that is outside an angular range defined by an access region of the opening.
