Air induction bowl for use with a detergent dispenser
First Claim
1. A bowl for use in a chemical dispenser, the bowl being adapted to support an inverted container of solid cast chemical and having a jet for directing a spray of liquid from a liquid source on the solid cast chemical to generate a chemical solution thereof, the chemical dispenser having a valve for control of the liquid supplied to the chemical dispenser, the valve being in flow communication with the jet, comprising:
- a container receiver portion having an upwardly directed container opening defined therein for receiving an inverted container and presenting an inner surface for supporting the container in an inverted disposition;
an accumulator portion depending from and in fluid communication with the container receiver portion, the jet being disposed therein; and
a discharge portion depending from and in fluid communication with the accumulator portion, the discharge portion defining a fluid discharge passageway for discharging chemical solution and having an air induction opening, the air induction opening being in fluid communication with the fluid discharge passageway and being spaced apart from the jet, the air induction opening acting to isolate the jet from chemical solution that may backup from the fluid discharge passageway, thereby preventing the contamination of the liquid source with chemical solution flowing through the jet.

Abstract
A chemical dispenser that uses an air induction bowl and the air induction bowl. The bowl is adapted to support an inverted container of solid cast chemical and has a jet for directing a spray of liquid on the solid cast chemical to generate a solution thereof. The chemical dispenser has a valve for control of the liquid supplied to the chemical dispenser, the valve being in flow communication with the jet. The bowl comprises a container receiver portion having an upwardly directed container opening defined therein for receiving an inverted container. The container receiver portion presents an inner surface for supporting the container in an inverted disposition. An accumulator portion of the bowl depends from and is in fluid communication with the container receiver portion. The jet is disposed in the accumulator portion of the bowl. A discharge portion depends from and is in fluid communication with the accumulator portion. The discharge portion has an air induction opening that is in fluid communication with the accumulator portion.

13. A chemical dispenser for dispensing a chemical solution having a valve being in flow communication with a source of fluid, a jet being in flow communication with the valve, a bowl for supporting a container of solid cast chemical, the jet being disposed within the bowl to cause a spray of liquid to impinge upon the solid cast chemical to form a chemical solution, and a solution discharge port being in flow communication with the bowl, comprising:
overflow means operably fluidly coupled to the bowl and the valve for providing a path of discharge of backed up chemical solution from the solution discharge port, whereby the discharge of the backed up chemical solution through the overflow means is substantially isolated from the jet disposed within the bowl and from the valve that is in flow communication with a source of fluid from interaction with the backed up chemical solution such that backed up chemical solution does not contaminate the source of fluid either through the jet or through the valve. - View Dependent Claims (14, 15)
