The invention belongs to the technical field of dish washer, and in particular relates to a slag disintegrating-draining linkage apparatus and a dish washer provided with the apparatus. The slag disintegrating-draining linkage apparatus is characterized in that: a mechanical structure controls a slag disintegrating blade and a draining valve to work in cooperation; a driving mechanism rotates in forward direction so as to drive the draining valve to close and at the same time drives the slag disintegrating blade to rotate and disintegrate slag; when slag disintegrating is completed and the driving mechanism rotates in a reverse direction, the driving mechanism controls the draining valve to open, and discharges the disintegrated slag. The slag disintegrating-draining linkage apparatus requires only one power source to rotate the driving mechanism in a forward and reverse direction so as to achieve the functions of closing the draining valve and disintegrating slag and the functions of opening the draining valve and discharging slag. Compared with prior art technology in which a computer programs is employed in controlling the slag disintegrating blade and the draining valve to work in cooperation, the slag disintegrating-draining linkage apparatus of the invention has the advantages of reliable control, accurate time coordination, and simple structure, and is suitable for promotion and application.
