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.

A dishwasher having variable spray patterns and having no spray arms, the dishwasher comprising:
- a washing container;
- a variable spray device structured to spray a liquid into the washing container, the variable spray device including a chamber for receiving the liquid therein and a liquid deflector disposed at a bottom portion of the chamber, the liquid deflector having a geometrically shaped perimeter that allows for the generation of a centrifugal force within the chamber used in directing the spray of the liquid into the washing container, wherein the liquid directly enters the washing container after contacting the liquid deflector;
- and
- a horizontal channel at a bottom position of the chamber structured to direct the liquid in a horizontal direction towards an external surface of the deflector and into the chamber.
A variable spray device not disposed on a spray arm operable to spray a liquid into a washing container, the variable spray device comprising:
- a chamber for receiving the liquid therein;
- a liquid deflector disposed at a bottom portion of the chamber, the liquid deflector having a geometrically shaped perimeter that allows for the generation of a centrifugal force within the chamber used in directing the spray of the liquid into the washing container, wherein the liquid directly enters the washing container after contacting the liquid deflector;
- and
- a horizontal channel structured at a bottom position of the chamber to direct the liquid in a horizontal direction towards an external surface of the liquid deflector and into the chamber.
