Abstract
A dishwasher including a variable spray device operable to spray a liquid into a washing container of the dishwasher, the variable spray device, and a method thereof. The variable spray device may be structured to include a chamber for receiving the liquid therein, such as a dishwashing liquid or water, and a liquid deflector disposed in the chamber. The liquid deflector may have a geometrically shaped perimeter, for example, a conical shape, that allows for the generation of a centrifugal force within the chamber used in directing the spray of the liquid into the washing container. By varying a force or pressure of the liquid as it interacts with the liquid deflector in the chamber, variable spray patterns may be generated.
