Combined vacuum and steam cleaner - has Venturi duct which draws water from container to remove dirt contained in main stream

摘要

The box-like (10) machine has a vacuum-cleaner section composed of a fan (12) that is coupled to an electric motor (13). The intake of the fan is connected to a dirt suction duct (14). In the vacuum-cleaner section, upstream of the fan (12), the discharge of the fan generates a secondary air stream, separate from a main stream that contains dirt, in one Venturi duct (32a,32b) that draws water from a water container (15) and ends in a region where the main air steam passes, to wet and remove the dirt contained in the main stream.
