HEAD FOR VACUUM CLEANER ADAPTED FOR BOTH WET AND DRY CLEANING (VERSIONS) Russian patent published in 2006 - IPC A47L9/02 

FIELD: equipment for vacuum cleaners intended for both wet and dry cleaning of surfaces in rooms by spraying and sucking of water during movement over surface on area under cleaning process.

SUBSTANCE: cleaning head has suction head designed for sucking washing liquid and foreign matter during displacement over floor and mounted at end of extension tube connected to main casing of vacuum cleaner, sprayer disposed on upper surface of suction head and adapted for spraying of washing liquid toward front end of suction head, and closure for head designed for defining channel for sprayed liquid on upper surface of suction head, said channel being adapted for flowing thereon of washing liquid sprayed from said sprayer. Ribs are formed downstream at discharge side of channel for sprayed liquid, said channel being restricted with head closure. Ribs have penetration portions provided with gaps of predetermined size between adjacent downstream ribs, through which gaps washing liquid is flowing. According to another version, suction head has rib provided upstream and extending transverse to channel for sprayed liquid, said channel corresponding to gap between sprayer and downstream ribs. Said upstream rib is formed on lower surface of head closure and disposed so that its upper surface is tightly contacting with suction head in order to provide distribution of liquid sprayed by means of sprayer and feed it to downstream ribs. Sealing material is provided between upper part of upstream rib and upper surface of suction head in order to ensure sealing therebetween.

EFFECT: simplified wet cleaning procedure, provision for spraying of water and/or detergent over wider area and sucking contaminated water from floor surface during shorter period of time.
