LOAD-SENSITIVE DISHWASHER MACHINE

A dishwasher rack (100; 720) for use in a load-sensitive dishwasher machine (700) comprises a plurality of rods (110; 210, 212), which are arranged to define at least one receptacle (150a-150c; 250) for an item to be washed, and at least one inlet (120). Each of the rods (110; 210, 212) comprises a duct (240, 242) for ducting cleaning liquid in an extension direction of the rod (110; 210, 212), and at least one duct opening (112; 214, 216) adjacent to the at least one receptacle (250). The duct (240, 242) of each rod (110; 210, 212) is fluidly connected to the inlet (120) such that a fluid connection exists between the inlet (120) and the duct opening (112; 214, 216). The duct (240, 242) of each rod (110; 210, 212) is further configured for ducting light parallel to the extension direction of the rod (110; 210, 212), the duct (240, 242) being connected to the inlet (120) in a light-conducting manner such that a light-conducting connection exists between the inlet (120) and the duct opening (112; 214, 216). The rods (110; 210, 212) comprise at least one first rod (210) and at least one second rod (212) which are arranged on different sides of the receptacle (150a-150c; 250), and the duct opening (214) of the first rod (210) faces the duct opening (216) of the second rod (212), such that a light barrier of an optical load-sensing system of the dishwasher machine is constituted in the receptacle (150a-150c; 250) between the first rod (210) and the second rod (212), when light is irradiated into the inlet by means of a light source of the load-sensing system. Further described are a load-sensing system (710), a dishwasher machine (700) and a method (800).
