Abstract

A dishwashing machine including a comminution device and a method for comminuting residue in the dishwasher. The comminution device at minimal manufacturing costs, makes it possible to easily comminute the coarse contaminants or residue accumulating during the rinse cycle in the dishwashing machine, flush it out of the dishwasher and at the same time reduce the danger of clogging the sieve(s) placed in the dishwasher. The comminution device preferably is actuated by the lye pump of the dishwashing machine. In this manner the comminution device is actuated easily and efficiently, which both enables cost-effective manufacture of the dishwashing machine, and improves its operating safety and ease of maintenance. In the process the rinse residue can first collect during the rinse cycle in uncomminuted form on the floor of the rinsing container and only then be comminuted when the washing liquid is pumped out and flushed out of the dishwashing machine.
