  • the spray arm assembly comprises an electricity storing unit for storing electricity generated by the electricity generator.
  • the spray arm assembly comprises a water pressure sensor, the controller configured to use information from the water pressure sensor to predict a trajectory of water from the spray holes.
  • the spray arm assembly comprises a speed sensor for sensing rotational speed of the spray arm, the controller configured to use rotational speed information obtained from the speed sensor in selectively arranging each of the plurality of spray holes in the first configuration or the second configuration.
  • a dishwashing machine comprising a spray arm assembly according to any of the first aspects.
  • a method of controlling a spray arm assembly of a dishwashing machine comprising: sensing by a sensor one or more items to be washed in a dishwashing machine, so as to generate position information of the one or more items to be washed; and selectively arranging each of a plurality of spray holes of the spray arm in a first configuration or a second configuration in dependence on the position information, the spray holes for spraying water in the dishwashing machine and the first configuration permitting ejection of water and the second configuration preventing ejection of water.

  • FIG. 1 schematically shows an example of a dishwashing machine 100.
  • the dishwashing machine 100 comprises a main body 102, within which there is a washing compartment or chamber 104.

  • a problem which has been recognised by the present inventors is that a dishwasher may be only partially filled when a dishwashing cycle is begun, and the items in a partially filled dishwashing machine may not be evenly distributed in the racks of the machine. Therefore at least some of the water ejected from the spray arms may be wasted if that water does not contact any items in the machine during a washing cycle. This can lead to a waste of resources e.g. a waste of water, a waste of power used to eject that water etc.

  • the water pump 150 can pump water to spray arms 124 and 126. Water that has been sprayed falls back down to a base or sump 152 of the dishwashing machine 100, from where that water can be recycled (after filtering, in some examples) by the pump 150.
  • rotation of the spray arms 124 and 126 is effected by the force of water being ejected from spray holes of the spray arms.
  • the spray holes may be arranged and/or oriented so as to facilitate such rotation.
  • one or more motors shown schematically at 148, may be provided for powering rotation of the spray arms 124 and 126.

  • the door 140 is connected to main body 120 via hinges 142 and 144.
  • the door is in an open position enabling access to washing compartment 104.
  • the door 140 may be moved to a closed position so that the washing compartment 104 is then substantially enclosed.
  • the door 140 may also include a receptacle for holding dishwashing detergent (e.g. a detergent cube) which can be released in to the dishwashing machine during a wash.
  • the receptacle for holding washing detergent may of course also be positioned elsewhere within the dishwashing machine.
  • the dishwashing machine may also include one or more further receptacles for containing dishwashing machine salt and/or rinse aid, for example.

  • every spray hole on the spray arm 224 can be selectively switched between open and closed configurations.
  • a plurality (but not all) spray holes can be selectively switched between open and closed configurations e.g. some may simply be open at all times. It will of course be understood that one or more spray holes may be configured in their open configurations whilst one or more other spray holes are configured in the closed configuration.
  • each spray hole is independently controllable between open and closed configurations.
  • a sensor 278 is provided for determining a rotational speed of the spray arm 224.
  • the sensor 278 comprises an accelerometer.
  • the sensor 278 comprises an encoder e.g. an optical encoder such as an encoder wheel.
  • the sensor 278 may be considered a speed or velocity sensor.
  • Controller 282 may use rotational speed information obtained from the speed sensor 278 in selectively arranging each of the plurality of spray holes in the first configuration or the second configuration.

  • the controller 282 is in communication with sensor 272, the plurality of movable elements 274 and 276 (which in this example may be via communication with respective solenoid units 275 and 277), speed sensor 278 and pressure sensor 280.
  • the controller 282 comprises a microcontroller unit (MCU).
  • the controller 282 comprises control circuitry.
  • the controller 282 can establish position information of items to be washed in a dishwasher. This position information may be stored in memory 284.
  • the spray arm 224 is controlled so as to perform one or more scanning rotations prior to a start of a washing cycle, so as to enable the positional information of the items to be washed to be obtained using the sensor 272.
  • a washing cycle is started only once the positional information of the items to be washed has been obtained. This minimises wastage of water.
  • the controller 282 may store an image recognition or machine learning algorithm enabling the controller to distinguish between sensed items according to type. For example the controller 282 may be able to distinguish between an item to be washed and a rack which is for holding items to be washed.

For example the controller may determine that a larger plate will require more water for cleaning than a smaller plate, and configure one or more of the spray holes accordingly.

  • a configuration of a respective spray hole is set, and then maintained constantly during a washing cycle or stage of a washing cycle.
  • a spray hole will be open or closed throughout a washing cycle or stage of a washing cycle.
  • a configuration of a respective spray hole may be changed one or more times, for example multiple times, during a washing cycle. That is it may be considered that the open or closed configuration can be dynamically changed during a washing cycle.
  • an open or closed configuration of a spray hole may be dependent upon a rotational position of the spray arm 224.
  • a configuration (open or closed) of a spray hole may change one or more times during a rotation of spray arm 224, and this may be repeated for each rotation. That is a spray hole may be configured in its open or closed configuration based on a rotational position of the spray arm. This allows a spray hole to eject water when the spray hole is in the vicinity of an item to be washed, and to be closed when in a position where there are no items to be washed.
  • information from the speed sensor 278 is used in order to detect a rotational position of spray arm 224.

  • the axle 288 remains stationary as the spray arm 224 rotates about it.
  • a rotor is schematically shown at 292.
  • the rotor 292 rotates as the spray arm 224 rotates. It may therefore be considered that the rotor 292 is fixed for rotation to the spray arm 224.

  • the controller 282 and/or sensor 272 may be encased in waterproof casings.
  • a seal 298 may be provided between the inlet 280 and the spray arm 224 to prevent unwanted leakage of water out of inlet 270 and/or in to spray arm 224 (of course while still allowing water to pass to the spray holes).
  • the spray arm assembly 221 may be retrofitted in to existing dishwashing machines. Since in some examples the spray arm assembly 221 is self-contained and comprises its own sensors, controller and electrical generator unit, then no additional hardware or software would be required in an existing dishwashing machine to include the spray arm assembly 221. This enables existing dishwashing machines to benefit from improved water efficiency. Of course, in other examples the spray arm assembly 221 may be installed in new dishwashers to provide such dishwashers with a water efficient spray arm assembly.
