Abstract (en)
[origin: EP0460250A1] The present invention refers to a dishwashing machine having a high precision in the washing water dosage, which comprises a water collecting sump (2) arranged under the lower wall (3) of a washing chamber (4) and with a mouth defined in said lower wall (3). Sump (2) has at least a first port (5) communicating with the suction pipe of a pump (7) connected by its delivery side to at least one water spraying arm (8) arranged inside said washing chamber (4). In said sump (2) are provided water level sensor means (10). Said sump (2) shows a working volume at least equal to the difference between the total volume of water required for the operation of the machine and the volume of water kept in circulation, outside said sump (2), when the pump (7) is working. In corrispondence of the level (9) reached in said sump (2) by a water quantity equal to said difference, said sump (2) shows, in a horizontal plane tangent to the water surface, a passage section smaller than the section of the washing chamber (4).
