US 2023/0416966 A1 · LAUNDRY WASHING MACHINE WITH DYNAMIC RINSE SYSTEM

Abstract

A laundry washing machine and method utilize a fluid property sensor to sense a fluid property of a fluid during a wash cycle to sense the level of detergent remaining in a load and control a rinse operation performed thereafter based upon the sensed fluid property. In some instances, the fluid property may be sensed while the load is being spun at a rate sufficient to cause fluid to be released from the load such that the sensed fluid property is based at least in part on fluid that was previously absorbed into the load. In addition, in some instances, the fluid property may be sensed during a spin phase of a wash cycle to selectively cause a wash cycle to selectively revert to an additional rinse phase when required, or otherwise proceed directly to the remainder of the spin phase to complete the wash cycle.

Dependent claims

A laundry washing machine, comprising:

a wash tub disposed within a housing;
a wash basket disposed within the wash tub and rotatable about an axis of rotation;
a drive system coupled to the wash basket to spin the wash basket about the axis of rotation;
a fluid property sensor configured to sense a fluid property that varies with an amount of detergent in fluid from the wash tub;
and
a controller coupled to the drive system and the fluid property sensor, the controller configured to, during a wash cycle for a load disposed in the wash basket, control the drive system to spin the wash basket to cause fluid to be released from the load and into the wash tub, determine with the fluid property sensor a fluid property value associated with the fluid released from the load and into the wash tub, and to control a rinse operation performed thereafter during the wash cycle based at least in part upon the determined fluid property value.
