Abstract

Herein is described an apparatus applicable to washing machines for the introduction of controlled and measured quantities of a liquid into another body of liquid. The apparatus consists of a revolving mechanism in communication with the fluid to be injected and a motor (12) for the rotation of the revolving mechanism. The revolving mechanism has on its perimeter one or more openings (2) each with a deflector (3) placed on the side of the opening (2) in the direction of the rotation of the revolving mechanism. Its rotation and the consequent deformation of the streamline flow (5) of the liquid in which the revolving mechanism rotates establishes a suction condition at the openings of the revolving mechanism which favors the injection of the liquid from the revolving mechanism into the liquid of the body.

Claims

1. Apparatus for introduction of metered quantities of an additive liquid to be injected into another body of liquid, comprising in combination, means for injecting the additive liquid into the body of liquid by rotating a revolvable hollow mechanism in a single direction of rotation, said mechanism having at least one opening and a deflector extension protruding radially beyond the opening adjacent only that side of the opening in the single direction of rotation shaped and spaced from the opening for deflecting the liquid of the body to create a suction at the opening sufficient to draw the additive liquid from a store of the additive liquid through the hollow mechanism, means positioning the revolvable mechanism in said body of liquid for rotation therein, a store of liquid to be metered into said body of liquid in communication with said hollow mechanism to permit flow into the liquid body responsive to said suction, and regulating means for controlling rotation of said mechanism to introduce a predetermined measure of liquid from said store of liquid through said mechanism into said liquid body.

2. Apparatus as defined in claim 1 wherein the injected liquid is metered into the body of liquid by means adjusting the level of the body of liquid in which the mechanism revolves thereby to inject the store of liquid only when the revolving mechanism becomes immersed into the body of liquid.

3. The method of sucking an exterior additive washing liquid into a liquid body of a washing machine from a rotating hollow body in the washing machine through a rotatable opening therein comprising the steps of rotating the body and opening in a single direction for sucking the additive liquid into the liquid body, providing deflection means radially extending from the rotating body adjacent to and on the side of the opening in the direction of the rotation with such shape to produce upon rotation in the liquid body lower fluid pressure in the liquid body at the opening to provide enough suction to suck the additive liquid from an exterior store into the liquid body, and coupling an exterior source of additive liquid to the opening for suction into the liquid body as a result of the rotation of the body.

4. The method defined in claim 3 including the step of washing articles in the body of liquid and controlling a washing chemical by the injection of the exterior liquid into the liquid body within a container only when the level of the liquid body immerses the hollow body to thereby produce said suction.
