Abstract:
1. An appliance, comprising: a pump configured to pressurize a washing fluid; a spray arm in fluid communication with the pump, the spray arm comprising a spray jet through which flows the washing fluid at a spray velocity and an angle fixed relative to the spray arm; and a controller with a pump motor control circuit coupled to the pump and configured to generate a variable frequency, single-phase alternating current input, the controller comprising a processor, memory coupled to the processor, and executable instructions stored on memory and configured to be executed by the processor, the executable instructions comprising instructions for implementing an operational cycle that assigns values to the frequency of the variable frequency, single-phase alternating current input to eject the washing fluid at different washing stream locations on an object, and wherein the pump is configured to change the spray velocity of the washing fluid in response to the frequency of the variable frequency, single-phase alternating current input.
