Conveyor dishwasher and method for operating a conveyor dishwasher

A conveyor dishwasher, comprising:

• a conveyor apparatus for conveying washware through multiple treatment zones of the conveyor dishwasher;
• a detection system configured to detect the presence of washware or a washware carrier in a first predefined region at an inlet or at a feed of the conveyor dishwasher and to detect the presence of washware or a washware carrier in a second predefined region at an outlet of the conveyor dishwasher;
• and
• a control device configured to control activation of the conveyor apparatus, wherein the control device is configured to control activation of the conveyor apparatus differently as between a first operating state and a second operating state of the conveyor dishwasher, in the first operating state the control device activates the conveyor apparatus independently of whether washware or a washware carrier is present in the first predefined region at the inlet or in the feed of the conveyor dishwasher and, in the second operating state the control device actuates the conveyor apparatus in such a way that both:
• (i) the conveyor apparatus is activated when washware or a washware carrier is respectively detected in both the first predefined region at the inlet or feed of the conveyor dishwasher and in the second predefined region at the or in the outlet of the conveyor dishwasher;
• and
• (ii) the conveyor apparatus is deactivated when no washware or no washware carrier is detected in the first predefined region at the inlet or feed of the conveyor dishwasher and an item of washware or a washware carrier is detected in the second predefined region at the or in the outlet of the conveyor dishwasher.

A conveyor dishwasher, comprising:

• a conveyor apparatus for conveying washware through multiple treatment zones of the conveyor dishwasher;
• a detection system configured to detect the presence of washware or a washware carrier in each of (i) a first predefined region at an inlet or at a feed of the conveyor dishwasher and (ii) a second predefined region of an outlet of the conveyor dishwasher, wherein the second predefined region is at an upstream end of the outlet, as seen in a conveyance direction of the conveyor apparatus;
• and
• a control device associated with the detection system and configured to control the conveyor apparatus based upon each of:
• (i) detection of washware or a washware carrier in the first predefined region,
• and
• (ii) detection of washware or a washware carrier in the second predefined region;
• wherein the detection system is also configured to detect the presence of washware or a washware carrier in (iii) a third predefined region of the outlet of the conveyor dishwasher, wherein the third predefined region is at a downstream end of the outlet, as seen in the conveyance direction;
• wherein the control device is also configured to control the conveyor apparatus based upon (iii) detection of washware or a washware carrier in the third predefined region.
