Abstract
A dishwasher (1) in the form of a commercial utensil washer or dishwasher which is designed as a batch dishwasher and is realized as a hood-type dishwasher, wherein the dishwasher (1) has a treatment chamber (2) with at least one wash system which is designed as a recirculation system, wherein the treatment chamber (2) has a first treatment zone (6) and at least one further, second treatment zone (7), wherein items of washware can be treated independently of one another and at least temporarily at the same time in the first and in the at least one second treatment zone (6, 7).
Claims10
A hood-type batch dishwasher, comprising:
- a treatment chamber with a wash system which is configured as a recirculation system, wherein the treatment chamber is divided into a first treatment zone and a second treatment zone, wherein the first treatment zone and the second treatment zone are arranged one above the other, wherein the wash system includes first wash nozzles that spray into the first treatment zone and second wash nozzles that spray into the second treatment zone;
- a final rinse system configured for enabling final rinsing within the first treatment zone independently of final rinsing in the second treatment zone, the final rinse system including a plurality of first final rinse nozzles that spray into the first treatment zone, and a plurality of second final rinse nozzles that spray into the second treatment zone, wherein the second final rinse nozzles are separate from the first final rinse nozzles so that final rinse spraying within the first treatment zone can take place independently of final rinse spraying within the second treatment zone;
- a control device configured for actuating the wash system and the final rinse system, wherein the control device includes at least one stored cleaning program by which the control device is configured to carry out overlapping treatment cycles in the first treatment zone and the second treatment zone, which includes actuating the wash system and the final rinse system in such a way that:
- a wash cycle step of a first treatment cycle in the second treatment zone overlaps with both a wash cycle step of a first treatment cycle in the first treatment zone and a wash cycle step of a second treatment cycle in the first treatment zone;
- a final rinse cycle step of the first treatment cycle in the second treatment zone (i) does not overlap with a final rinse cycle step of the first treatment cycle in the first treatment zone and (ii) overlaps with a final rinse cycle step of the second treatment cycle in the first treatment zone.
A hood-type batch dishwasher, comprising:
- a treatment chamber with at least one wash system that is configured as a recirculation system, wherein the treatment chamber is divided into a first treatment zone and a second treatment zone, wherein the first treatment zone is above the second treatment zone, wherein the first treatment zone includes a hood which is vertically movable between a position to access the first treatment zone through a first opening to the first treatment zone and a position to close the first opening, and wherein the second treatment zone includes a door that is separate from the hood and is pivotally moveable between a position to access the second treatment zone through a second opening to the second treatment zone and a position to close the second opening;
- a final rinse system configured for enabling final rinsing within the first treatment zone independently of final rinsing in the second treatment zone;
- a single wash tank located below the second treatment chamber for collecting sprayed liquid that falls from both the first treatment zone and the second treatment zone.
