Logging of fault and operational data for household appliances e.g. washing machine, spin drier - using built in memory to store data that can be displayed or used for statistical processing

摘要

Items of domestic equipment are fitted with monitoring and data logging facilitates that allow the usage of different components and faults to be logged. The machines have built in processors and memories. Operating conditions, such as particular cycles, operational periods of components, number of switching cycles can be entered into areas of memory that can be accessed by service personnel. The memories can also be in the form of exchangeable items, such as EEPROM devices, that can be removed and the data accessed by the manufacture to be processed to generate statistical trend information. ADVANTAGE - Allows operational data to be logged.
