Abstract
A laundry washing machine and method automate the selection of a load type for a laundry washing machine during an initial fill phase of a wash cycle and based in part on weight and fluid level sensed by weight and fluid level sensors operatively coupled to a wash tub and after a selected amount of water has been dispensed into the wash tub.
Claims28
A laundry washing machine, comprising:
- a wash tub disposed within a housing;
- a water inlet configured to dispense water into the wash tub;
- a weight sensor operatively coupled to the wash tub to sense a weight associated with the wash tub;
- a fluid level sensor configured to sense a fluid level in the wash tub;
- and
- a controller coupled to the water inlet and the weight and fluid level sensors, the controller configured to initiate an initial fill phase of a wash cycle by controlling the water inlet to dispense water into the wash tub and to dynamically select a load type from among a plurality of load types during the initial fill phase of a wash cycle based upon weight and fluid level values sensed respectively by the weight and fluid level sensors after a selected amount of water has been dispensed by the water inlet.

A method of operating a laundry washing machine of the type including a wash tub disposed within a housing and a water inlet configured to dispense water into the wash tub, the method comprising:
- initiating an initial fill phase of a wash cycle by controlling the water inlet to dispense a selected amount of water into the wash tub;
- sensing a weight value associated with the wash tub with a weight sensor operatively coupled to the wash tub after the selected amount of water has been dispensed by the water inlet;
- sensing a fluid level value with a fluid level sensor that senses fluid level in the wash tub after the selected amount of water has been dispensed by the water inlet;
- and
- dynamically selecting a load type from among a plurality of load types during the initial fill phase of the wash cycle based upon the weight and fluid level values.
