Abstract
A dishwashing machine is provided for washing dishes with a very rapid washing cycle in which water and detergent are sprayed through different spraying nozzles in different operational stages within the dishwashing cycle.
Claims12
A dishwashing machine comprising:
- a dishwashing chamber configured as a single dishwashing compartment,
- a dish holder for holding dishes within said chamber, and
- a dishwashing assembly for washing dishes held within said chamber;
- said assembly comprises at least two liquid spraying sub-assemblies, of which at least one is a detergent spraying sub-assembly for spraying of detergent only and at least one other is a water spraying sub-assembly for spraying of water only, each of the liquid spraying sub-assemblies being activated to spray liquid in a different step of an operational cycle;
- each sub-assembly located within said single dishwashing compartment, each sub-assembly comprises a plurality of spray nozzles, one or more liquid ducts leading form a liquid reservoir to the nozzles, and a flow controller for rapid activation and inactivation of the spraying of liquid out of the nozzles;
- the nozzles of each sub-assembly being arranged so that their combined spraying will apply liquid on substantially all faces of the dishes, the nozzles being held on one or more arms moveable within the chamber, each such arm holding nozzles of all sub-assemblies, the arm being adapted to pass throughout the chamber at each of the steps of the operational cycle.

A dishwashing machine comprising:
- a dishwashing chamber having a single dishwashing compartment,
- a dish holder for holding dishes within said chamber, and
- a dishwashing assembly for washing dishes held within said chamber;
- said assembly including a single rotatable arm being adapted to pass throughout the chamber at each step of an operational cycle and at least two liquid spraying sub-assemblies, of which at least one is a detergent spraying sub-assembly for spraying of detergent only and at least one other is a water spraying sub-assembly for spraying of water only, each of the liquid spraying sub-assemblies being activated to spray liquid in a different step of the operational cycle, each sub-assembly located within said single dishwashing compartment;
- each sub-assembly comprises a plurality of spray nozzles, with said spray nozzles being located on said single arm, one or more liquid ducts leading from a liquid reservoir to the nozzles, and a flow controller for rapid activation and inactivation of the spraying of liquid out of the nozzles;
- the nozzles of each sub-assembly being arranged so that their combined spraying will apply liquid on substantially all faces of the dishes.

A dishwashing machine comprising:
- a dishwashing chamber configured as a single dishwashing compartment;
- a dish holder for holding dishes within said chamber, said dish holder including a loading-unloading rotatable tray divided by a vertical water impermeable partition into two identical portions, the tray being positioned such that when one of the identical portions is within the dishwashing chamber, the other of said portions is outside said chamber and by rotation of the tray the positions of the portions are replaced with one another, said partition being capable of water-tight engagement with adjacent wall portions of the dishwashing chamber;
- and
- a dishwashing assembly for washing dishes held within said chamber, said assembly including at least two liquid spraying sub-assemblies, of which at least one is a detergent spraying sub-assembly for spraying of detergent only and at least one other is a water spraying sub-assembly for spraying of water only, each of the liquid spraying sub-assemblies being activated to spray liquid in a different step of an operational cycle, each sub-assembly located within said single dishwashing compartment, each sub-assembly comprises a plurality of spray nozzles, one or more liquid ducts leading form a liquid reservoir to the nozzles, and a flow controller for rapid activation and inactivation of the spraying of liquid out of the nozzles, the nozzles of each sub-assembly being arranged so that their combined spraying will apply liquid on substantially all faces of the dishes, the nozzles being either
- (i) stationary and spatially distributed within said chamber so as to apply their liquid simultaneously on all dishes held on the dish holder within the chamber, or
- (ii) being held on one or more arms moveable within the chamber, each such arm holding nozzles of all sub-assemblies, the arm being adapted to pass throughout the chamber at each of the steps of the operational cycle.
