Method and device for weighing for a washing machine and its use in a system for tracing

摘要

The device has a processing unit (2) controlling a control unit (13) for raising a washing unit from a low position to a determined high position. A force sensor (6) is supported by a supporting point at a bottom of a tub (31) of a washing machine (3). A conversion unit (21) connected to an output of the sensor transforms a signal representing weight of the tub with its contents to data representing load introduced into the tub. Independent claims are also included for the following: (a) a weighing process for washing machine of the type equipped with a raised lifted tub (b) a utilization of a weighing device in a cloth traceability system.
