Abstract
A dishwashing machine is proposed which is considerably shorter in design than the previously used, continuously operated transport-dishwashers. In order permanently to reduce the consumption of water, energy and rinsing agent, the crockery in the individual crockery baskets is washed cyclical operation, the circuits of the rinsing apparatus being started up only in their respective time span within the wash program.
Claims20
A dishwashing machine for cleaning crockery, comprising:
- a crockery treatment chamber having an entry opening, including:
- a washing zone located immediately subsequent to the entry opening;
- a plurality of washing nozzles for washing the crockery within said washing zone during a program controlled washing cycle;
- a rinsing zone located immediately adjacent to and immediately following said washing zone;
- and
- a plurality of rinsing nozzles for rinsing the crockery within said rinsing zone during a program controlled rinsing cycle, the rinsing cycle occurring only during an inoperative stage of the washing cycle and during a transportation of the crockery;
- a program controlled transporting device longitudinally traversing said rinsing chamber for transporting the crockery through the entry opening, said washing zone and said rinsing zone, respectively;
- and
- program control means for automatically controlling the rinsing cycle, the washing cycle, and movement of said transporting device, said program control means causing the crockery to be transported on said transporting device through the entry opening and into said washing zone at a rapid speed, stopping said transporting device to cause the crockery to dwell within said washing zone during the washing cycle for a controlled period of time, and subsequently transporting the crockery into and through said rinsing zone simultaneous with the rinsing cycle.
