Abstract

Appliance (100) having a housing (101) of compact dimensions wherein articles, particularly nursing bottles (123, 179) and accessories (119), are treated inside a chamber (1). Treatment is achieved with dosed amounts of fresh water retrieved from a fresh water tank (7), by successive cycles of washing, rinsing, and sterilizing. The treatment cycles use additives and high-speed jets of heated liquid and of steam, which are filtered for repeated use. At the end of the treatment, liquids are purged to a wastewater tank (33). Self-treatment of the appliance is provided by use of the same treatment cycles. The appliance is independent of external water supply, portable and automatic for use in situ, where electricity supply is available.
