CONTROL AND WASH CYCLE FOR ACTIVATION AND DEACTIVATION OF CHEMISTRY IN THE WASH BATH OF AN AUTOMATIC WASHER
First Claim
1. A control for an automatic washer to operate the washer through a wash cycle determined based upon various soils and stains in the substrate load to be washed with a wash liquor in a wash zone of the washer, the control comprising:
- a plurality of stain/soil type entré
es, which can be at least one of selected and detected, and cleaned with a particular wash cycle,dispensing control over at least one wash liquor additive from the group consisting of detergents, chlorine bleaches, color safe bleaches, cleaning boosters, oxidizing agents, pre-wash stain removers, pre-wash chemistries, switchable or tunable surfactants, wrinkle guard, color finishes, water repellency, stain guard, functional finishes, fabric softeners, water softeners, fragrances, anti-static agents, drying aids, de-wrinkling chemistries, deodorizers, surfactants, emulsifiers, enzyme activated stain removers, sudsing agents, builders, anti-redeposition polymers, in-wash stain removers and perfumes,operational control over activators and deactivators for members of the additives group, the activators and deactivators being from the group consisting of thermal, biological, chemical, electromagnetic and mechanical actions, andoperational control over the particular wash cycles using the dispensing control to dispense additives to the wash liquor at selected times during the wash cycle and operating the activators and deactivators at selected times during the wash cycle.

Abstract
A control for an automatic washer to operate the washer through a wash cycle determined based upon various soils and stains in the substrate load to be washed with a wash liquor in a wash zone of the washer. The control has a plurality of stain/soil type entrées, which can be at least one of selected and detected, and cleaned with a particular wash cycle. The control has dispensing control over at least one wash liquor additive. The control has operational control over activators and deactivators for members of the additives group. The control has operational control over the particular wash cycles using the dispensing control to dispense additives to the wash liquor at selected times during the wash cycle and operating the activators and deactivators at selected times during the wash cycle.
