Abstract: |
A method and apparatus for detecting the relative proportion of various fabric types present in a clothes load in a clothes washer are provided, in which a set of fuzzy logic membership functions is defined at each clothes load weight across a range of expected load weights to be handled by the clothes washer, with the set of membership functions representing various fabric types that might be present in the clothes load. The membership functions are defined at least in part by a washer operating state that is to be sensed during initial washer operation, and the method includes obtaining a value for the clothes load weight, sensing a value of the washer operating state, and determining a degree of fulfillment of the sensed value in each of the membership functions defined for that given clothes load. The degree of fulfillment represents the relative proportion of the various fabric types for which membership functions are defined, and the information regarding the resultant degrees of fulfillment may be employed in controlling the operation of the washer for optimal performance. The apparatus constitutes a washer controller having a microprocessor that receives signals corresponding to the weight of the clothes load, the sensed value of the predetermined washer operating state, and has stored therein the data necessary to generate the set of membership functions for each clothes load weight.

First Claim:

What is claimed is:
1. A method for detecting a mix of fabric types making up a load of items disposed in a clothes washer, comprising:
- obtaining a value of a dry weight of said load of items disposed in said clothes washer;
- developing for said dry weight value, a set of fuzzy logic membership functions corresponding to a plurality of fabric types that may be included in said load of items, each of said membership functions being dependent upon at least one washer operating state to be sensed;
- sensing a value of said at least one washer operating state; and
- computing a degree of fulfillment of the sensed value of said washer operating state in each of the set of membership functions, wherein said degree of fulfillment in each of said membership function represents the relative proportion of a fabric type represented by each of said membership functions.
