Claims
- 1. A household dishwasher, comprising:a dishwashing compartment; a circulating pump for delivering liquid to said dishwashing compartment; a flow heater having an inflow connection fluidically connected to said circulating pump and at least two outlet connections; at least two spray devices disposed in said dishwashing compartment and fluidically connected to a respective one of said at least two outlet connections for supplying the liquid to each of said at least two spray devices; said at least two spray devices disposed to subject items disposed in said dishwashing compartment to be cleaned to an action of a liquid delivered by said circulating pump; and a rotary valve disposed at said flow heater upstream of said at least two outlet connections with respect to a liquid flow direction, for selectively opening and closing said at least two outlet connections.
- 2. The dishwasher according to claim 1, wherein a number of said at least two outlet connections of said flow heater corresponds to a number of said at least two spray devices.
- 3. The dishwasher according to claim 1, wherein a number of said at least two outlet connections of said flow heater corresponds to a number of simultaneously operated groups of said at least two spray devices.
- 4. The dishwasher according to claim 1, where said at least two outlet connections are two outlet connections.
- 5. The dishwasher according to claim 1, wherein:said flow heater has an outlet opening disposed upstream of each of said at least two outlet connections in the liquid flow direction; and said rotary valve selectively closes said outlet opening.
- 6. The dishwasher according to claim 5, wherein that said rotary valve has at least one closed region and at least one open region with a bore.
- 7. The dishwasher according to claim 6, including a drive device connected to said rotary valve for moving said rotary valve into at least one of different positions selected from the group consisting of:a position where said at least one closed region closes said outlet opening; a position where a number of said at least one closed region closes a respective outlet opening; and a position where each outlet opening is open.
- 8. The dishwasher according to claim 7, wherein said drive device is a motor with a gear mechanism.
- 9. The dishwasher according to claim 6, wherein:said rotary valve has encircling ribs at each of said at least one open region and said at least one closed region; and said ribs have a semicircular cross section and project upward in a direction toward said outlet opening in an installed position of said rotary valve.
- 10. The dishwasher according to claim 5, wherein said rotary valve has a circulation direction and, alternately in said circulation direction, an open region followed by a closed region, said open region and said closed region defining an unfilled space therebetween.
- 11. The dishwasher according to claim 5, wherein said rotary valve has at least one alternating group of an open region followed by a closed region and said open region and said closed region defining an unfilled space therebetween.
- 12. The dishwasher according to claim 5, including a drive device connected to said rotary valve for moving said rotary valve into different positions and selectively opening and closing said outlet opening.
- 13. The dishwasher according to claim 12, wherein said drive device is a motor with a gear mechanism.
- 14. The dishwasher according to claim 5, wherein:said rotary valve includes a propeller blade having two mutually opposite regions; one of said opposite regions is a closed region; another of said opposite regions is an open region with a bore; said at least two outlets connections is two outlet connections; said flow heater has two outlet openings respectively disposed upstream of each of said two outlet connections in the liquid flow direction; and a drive device is connected to said propeller blade for moving said propeller blade into a position where said closed region closes one of said two outlet openings and said open region with said bore keeps another of said two outlet openings open.
- 15. The dishwasher according to claim 14, wherein said open region and said closed region each have an encircling rib having a semicircular cross section and projecting upward in a direction of said two outlet openings in an installed position of said rotary valve.
- 16. The dishwasher according to claim 14, wherein said drive device is a motor with a gear mechanism.
- 17. The dishwasher according to claim 1, wherein:said flow heater has an outlet opening disposed upstream of each of said at least two outlet connections in the liquid flow direction; and a speed of said circulating pump is reduced in periods of time when all outlet openings are open and when said at least two spray devices are continuously and alternately charged.
- 18. A household dishwasher, comprising:a dishwashing compartment; a circulating pump for delivering liquid to said dishwashing compartment; a flow heater having an inflow connection fluidically connected to said circulating pump and at least two outlet connections; two spray devices disposed in said dishwashing compartment and fluidically connected to a respective one of said two outlet connections for supplying the liquid to each of said two spray devices; said at least two spray devices disposed to subject items disposed in said dishwashing compartment to be cleaned to an action of a liquid delivered by said circulating pump; and a rotary valve disposed at said flow heater upstream of said at least two outlet connections with respect to a liquid flow direction, for selectively opening and closing said at least two outlet connections.
- 19. A method for washing dishware, which comprises:providing a dishwashing compartment with at least two spray devices disposed therein; fluidically connecting at least two outflow connections of a flow heater to the at least two spray devices; fluidically connecting an inflow connection of the flow heater to a circulating pump; fluidically connecting the at least two spray devices to a respective one of at least two outlet connections of the flow heater; subjecting dishware disposed in the dishwashing compartment and to be cleaned to an action of a dishwashing liquid by delivering the liquid from the circulating pump through the flow heater, the at least two outlet connections, and the at least two spray devices; and selectively opening and closing the at least two outlet connections with a rotary valve disposed at the flow heater upstream of the at least two outlet connections with respect to a liquid flow direction, the rotary valve configured to perform a function selected from the group consisting of: selectively opening and closing a respective one of said at least two outlet connections alternately one after another; selectively opening and closing a number of said at least two outlet connections alternately one after another; selectively opening and closing all of said at least two outlet connections alternately; selectively opening and closing a respective one of said at least two outlet connections on a permanent basis; selectively opening and closing a number of said, at least two outlet connections on a permanent basis; selectively opening and closing all of said at least two outlet connections on a permanent basis; selectively opening and closing a respective one of said at least two outlet connections alternately one after another and on a permanent basis; selectively opening and closing a number of said at least two outlet connections alternately one after another and on a permanent basis; and selectively opening and closing all of said at least two outlet connections alternately and on a permanent basis.
