Abstract
A treatment aid dispensing apparatus for an automatic treatment appliance includes a bulk treatment aid dispenser, a sensor coupled with the bulk treatment aid dispenser, and a controller coupled with the sensor and the bulk treatment aid dispenser. A quantity of an undiluted treatment aid can be determined by the controller prior to dispensing from the bulk treatment aid dispenser based upon information from the sensor indicative of a sensed concentration of the undiluted treatment aid. The controller can process the information from the sensor and control the operation of the bulk treatment aid dispenser.

A treatment aid dispensing apparatus for an automatic treatment appliance, the automatic treatment appliance having a treatment chamber, and optionally a water supply fluidly coupled with the treatment chamber, the apparatus comprising:
- a bulk treatment aid dispenser fluidly coupled with the treatment chamber and operable to dispense a selected volume of undiluted treatment aid into the treatment chamber;
- a sensor coupled with the bulk treatment aid dispenser for outputting information indicative of a sensed concentration of the undiluted treatment aid;
- and
- a controller coupled with the sensor and the bulk treatment aid dispenser for processing information received from the sensor and controlling the operation of the bulk treatment aid dispenser;
- wherein a quantity of the undiluted treatment aid can be determined by the controller prior to dispensing from the bulk treatment aid dispenser into the treatment chamber based upon the sensed concentration of the undiluted treatment aid.
