A single unit milk dispenser for producing hot frothed milk or hot non-frothed milk uses milk and steam. A reservoir supplies milk via an adjustable valve to a first chamber. For supplying frothed milk, steam is issued from a first steam outlet nozzle and mixes and froths with the milk in the first chamber and in an expansion chamber before being dispensed out of a collection chamber. For non-frothed milk, steam supplied from a second steam outlet nozzle is released to mix and swirl around with cold milk fed from the reservoir into the collection chamber. The rate of flow of milk out of the reservoir is normally adjusted for the two mode of operation, which mode is simply otherwise determined by which nozzle supplies steam, by turning a steam supply selection knob.

[ I claim:] [1.]1. A single unit milk dispenser for producing hot frothed milk and hot non-frothed milk using milk and steam, the dispenser comprising a reservoir for containing a supply of milk, means for supplying steam under pressure, a first chamber, an adjustable valve to allow a flow milk into the first chamber, a first aperture in the base of the first chamber, a first steam outlet nozzle directed towards the first aperture to blow the milk from the first chamber into an expansion chamber where the milk is frothed by the steam, a second aperture in the base of the expansion chamber leading to a collection chamber for collecting frothed milk that exits from the expansion chamber, and a dispensing outlet at the base of the collection chamber, a flow passage between the adjustable valve and the expansion chamber to allow milk to be supplied from the reservoir into the expansion chamber, a second steam outlet nozzle for supplying steam under pressure directed across the collection chamber above the dispensing outlet to swirl and heat milk passing through the second valve towards the dispensing outlet, means for selectively supplying steam either to the first steam outlet nozzle for providing hot frothed milk at the dispensing outlet or to the second steam outlet nozzle for providing hot-non-frothed milk at the dispensing outlet.
