A hood-type industrial dishwasher includes a first filtering element (1) introduced into an opening (2a) of a concave-shaped flat filter (2) suitable to act as a lid for the collecting sump (3) formed in the tank bottom, as well as a second filtering element (5) introduced into an opening formed at the bottom of the collecting sump (3) and partially received within a manifold (6) for the connection to the wash and drain pumps which is secured under said opening of the sump (3), said second filtering element (5) forming in combination with said first filtering element (1) a filter assembly extending between said flat filter (2) and a pipe (DP) leading to the drain pump. The presence of the first filtering element (1) to retain the largest residues and the proportions between the various passage cross-sections of the filter assembly allow to achieve a greater filtering effectiveness with reduced clogging risk. |
