Multitank conveyor-type dishwasher and an operating method for it
First Claim
1. Multitank conveyor-type dishwasher for washing items to be washed, comprising a conveying apparatus for conveying the item to be washed through the multitank conveyor-type dishwasher in a conveying direction;
- at least two cleaning zones which are arranged in succession in the conveying direction and a final-rinse zone downstream, as seen in the conveying direction, of the cleaning zones;
wherein each cleaning zone has an associated tank and associated spray nozzles for spraying liquid from the associated tank onto the item to be washed;
a liquid forward-flow apparatus between the two successive cleaning zones for transferring liquid between these cleaning zones in a forward-flow direction counter to the conveying direction;
characterized in that a liquid recirculation apparatus is provided for transferring liquid, which has been deflected by the item to be washed counter to the conveying direction, from a front cleaning zone, as seen in the conveying direction, into a rear cleaning zone which is arranged downstream of the front cleaning zone, as seen in the conveying direction;
wherein the liquid recirculation apparatus has a recirculation line and an associated pump for pumping the liquid of the front cleaning zone into the rear cleaning zone; and
wherein the liquid recirculation apparatus is designed to pump liquid to the tank which is associated with the rear cleaning zone.
