CONSTRUCTION OF VACUUM-CLEANER MAIN CASE Russian patent published in 2010 - IPC A47L9/00 A47L9/22 

FIELD: articles of personal use.

SUBSTANCE: invention relates to vacuum-cleaner intended for collection of dust or polluting particles with application of dust bag, installed inside main case of vacuum cleaner. Vacuum cleaner contains sucking nozzle for sucking of air, flexible hose, connected with one end to sucking nozzle for directing of sucked through sucking nozzle air, and main case, connected with one end to flexible hose for cleaning of sucked air with caught by it polluting particles and including engine compartment for placement of at least engine, which creates sucking force. Engine compartment contains exhaust device providing outlet of air which gets into engine compartment. Vacuum cleaner has lower casing for placement of engine compartment with partly open upper part for directing air from engine compartment upward and intermediate unit, located on upper side of lower casing, in which at least dust-collecting device is formed. On upper part of intermediate unit handle is made. Inside dust-collecting device located is dust-collecting construction, representing dust bag, for filtration of air with polluting particles which gets into dust-collecting device. On upper side of intermediate unit installed is lid of dust-collecting device for selective opening of dust-collecting device.

EFFECT: construction of main case of vacuum cleaner allows to prevent arising during its operation deformation of components due to installation of separate element into dust-collecting compartment and eliminate possibility of dust bag rupture during vacuum cleaner operation.
