WASH CYCLES USING OXIDIZING AGENTS AND SENSORS
First Claim
1. A wash cycle comprising the steps:
- loading a wash machine with a fabric load for cleaning,selecting a wash cycle based on at least a color of the fabric load,determining a load size and type,dispensing wash water into the wash machine to form a wash liquor,sensing water quality of the wash water,determining an amount of detergent to add into the wash liquor and a length of time for the wash liquor to be presented to the wash load based on the previous selecting, determining and sensing steps,determining an amount of oxidizing agent to add into the wash liquor and a time for adding the oxidizing agent to the wash liquor based on the selecting, determining and sensing steps,performing washing steps of flexing the fabric load in the presence of the wash liquor, rinsing the fabric load and extracting liquid from the fabric load, while dispensing the detergent and oxidizing agent in accordance with the determinations made, anddrying the load based on the selecting, determining and sensing steps.

Abstract
A substrate treating appliance utilizing a plurality of different chemistries for different cycles or different wash loads with a plurality of receptacles for receiving a plurality of cartridges containing the different chemistries. Each receptacle has one half of a lock and key connection arrangement providing a unique interconnection configuration at each receptacle, relative to the remaining receptacles, permitting only a selected type of chemistry cartridge to be accepted at a particular receptacle. A connection effected between the cartridge and the receptacle occurs by rotation of the cartridge relative to the receptacle between an insertion orientation and a locking orientation. Each receptacle is shaped to receive a cylindrical mouth wall of a particular type of chemistry cartridge. Each receptacle may also be uniquely sized, relative to the remaining receptacles, to accept only a selected type of chemistry cartridge. The plurality of receptacles may be arranged adjacent to one another with each cartridge having a configuration that prevents insertion of a cartridge into a receptacle unless every cartridge located in an adjacent receptacle is rotated to the locking orientation.

21. A wash appliance comprising:
-
a wash zone configured to receive a load of fabric to be washed in a wash liquor during a wash cycle, lighting apparatus arranged to illuminate the wash zone and the fabric load in the wash zone, a digital optical device arranged to capture a digital image of the illuminated fabric load in the wash zone, at least one sensor arranged to sense a characteristic of the wash liquor during the wash cycle, the characteristic selected from the group consisting of pH, ORP, temperature, conductivity and turbidity.
