Abstract: A control method for a water diversion device, a water diversion device and a dishwasher. The control method for a water diversion device includes: acquiring a target state position to be reached by a water diversion piece; acquiring the current state position of the water diversion piece; controlling a driving component to operate, and counting the number of signals actually received; on the basis of the target state position, the current state position and the number of signals actually received, determining whether the water diversion piece has reached the target state position; and when the water diversion piece has reached the target state position, controlling the driving component to stop rotating.

Abstract: A control method for layered washing in a dishwasher and a dishwasher itself, which includes: S101: determining a rack that holds items to be washed; S102: determining a first spray water path corresponding to the rack that holds the items to be washed; S103: controlling a water divider piece to rotate to a position that opens the first spray water path, thereby connecting the first spray water path to a water supply device and closing other spray water paths; S104: performing a pre-washing step, so that the spray water path sprays towards the rack holding the items to be washed. The method first determines the rack holding the items to be washed, and then determines the first spray water path of the rack, so that the first spray water path is connected to the sink, and other spray water paths are blocked from the sink.

Abstract: A filter structure of a dishwasher and a dishwasher, wherein the filter structure of the dishwasher comprises a filter screen, the filter screen comprises several first filter ribs and several second filter ribs, and the second filter ribs and the first filter ribs are arranged to cross each other so as to form a mesh structure. The filter screen of the filter structure is a mesh structure, which does not need post-perforation, thereby saving on fabrication costs. The filter screen comprises a mesh structure formed by the second filter ribs and the first filter ribs being arranged to cross each other. Not only do the second filter ribs and the first filter ribs enhance the strength of the filter screen, but the mesh structure also prevents the occurrence of a situation in which filter pores of a metal filter screen are blocked by washing impurities.
