Dishwasher operated solely by steam and hot water pressure

In a dishwasher:

• (a) a wash/rinse compartment with a door giving access to the compartment, the compartment being adapted to removably enclose a dish-carrying basket;
• (b) a tank underlying said compartment and adapted to receive water therefrom, the tank holding a predetermined volume of water;
• (c) a boiler containing a volume of water with heating means therein for heating the water and for generating steam in the boiler;
• (d) a first hollow wash arm rotatably mounted below the basket and having jets;
• (e) a steam jet enclosed in a perforated housing, the housing being partially submerged in the body of water and having an outlet disposed close to the jet;
• and
• (f) steam conveying means for conveying steam from the steam in said boiler to the jet and fluid conveying means for conveying steam and water from the housing to said wash arm, the force of the steam in passing from the jet and exhausting through said housing outlet entraining water from the housing interior so that both steam and hot water is sprayed by the wash arm jets onto the dishes in the basket.

In a dishwasher:

• (a) a wash/rinse compartment for receiving and supporting a dish-carrying basket;
• (b) a tank underlying said compartment and adapted to receive water therefrom, the tank holding a predetermined volume of water;
• (c) a boiler containing a volume of water with heating means therein for heating the water and generating steam within said boiler;
• (d) a first hollow wash arm for spraying water onto the dishes in said compartment;
• (e) a first means associated with said arm and boiler for conveying steam from said boiler and mixing it with a supply of water from the tank water for causing said hollow wash arm to direct steam and water against the dishes during the washing cycle;
• (f) a first hollow rinse arm mounted for spraying rinse water onto the dishes;
• (g) a second means associated with said rinse arm and said boiler for conveying hot water from said boiler to said rinse arm for rinsing the dishes during the rinse cycle;
• (h) means for feeding fresh water into said boiler;
• (i) means for feeding fresh water into said rinse arm;
• (j) a temperature controlled mixing valve for controlling the flow of fresh water from the fresh water supply to the rinse arm and mixing it with the hot water from the boiler for maintaining the same temperature for the rinse water;
• and
• (k) timing means for first activating said first means for washing the dishes for a predetermined time period and subsequently activating said second means for rinsing the dishes for a predetermined time period.
