AUTOMATIC VACUUM CLEANER WITH TWO LIQUID FILTERS USED FOR DRY AND WET CLEANING OF ROOMS Russian patent published in 2004 - IPC

FIELD: dust cleaning equipment used in tidying up of household and industrial rooms. SUBSTANCE: vacuum cleaner has body into which two liquid filters of primary and final purification of air are built. First filter is static, second is centrifugal interlocked with impeller of fan to from by that actuating mechanism generating balloelectric effect. Clear or opaque vessel for liquid is provided with branch pipe, comes in the form of body of revolution, which cylindrical wall has upper and lower flanges bent inwards and passing into two cylindrical surfaces. Upper flange is dipped into liquid with formation of static filter and lower flange with bottom bent in diametrical section passes into cone-shaped bottom of vessel. Sphere-shaped thin-walled shell dipped into vessel beneath wall of upper bent is attached to bottom of cover of upper part of body by means of several pillars, it carries level gauge and tube feeding liquid into device of wet cleaning of room. Ring-shaped inclined deflectors mounted on internal wall of body and on thin-walled shell ensure zigzag movement of air and impart vacuum cleaner with antibubbling and antioscillatory properties when moved. All above-mentioned parts and units have single vertical symmetry axis. Completion of vacuum cleaner with additional separable attachment ensures emptying of vessel during cleaning and on termination of room cleaning, level gauge indicates filling of liquid to required volume. EFFECT: given vacuum cleaner can operate as air cleaner under uninterrupted condition when connected to water main and wastewater disposal system or settling tank. 6 cl, 14 dwg
