VACUUM CLEANER Russian patent published in 2021 - IPC A47L9/16 

FIELD: vacuum cleaners.

SUBSTANCE: invention relates to a vacuum cleaner. The housing (20) of the vacuum cleaner contains a receiving device for receiving a cyclone dust separator assembly containing a primary cyclone dust separator (32) and a secondary cyclonic dust separator assembly. The air outlet (34) of the primary cyclone dust separator (32) is connected through a distribution channel system with the air inlets of the secondary cyclone dust separators (38). The primary cyclone dust separator (32) is equipped with a primary dust collection chamber (55), and the secondary cyclone dust separator assembly is equipped with a secondary dust collection chamber assembly. Secondary cyclone dust separators (38) form several groups of secondary cyclone dust separators, each of which is located in an in-line structure that at least partially extends along the edge of the cyclone dust separator assembly, made in the form of a cyclone chamber (23) and interchangeably located in the vacuum cleaner housing (20 ). The air inlets of the secondary cyclone dust separators (38) and the air outlet (34) of the primary cyclone dust separator (32) are located in a common air duct plane LF together with the distribution duct system. The distribution duct system (49, 87) contains a cyclone cover (46, 86) with at least one suction opening made so that while the receiving device is designed in the form of a suction chamber between the cyclone cover (46, 86) of the distribution duct system (49, 87) and a housing cover (24) equipped with a suction opening (25), a closed suction compartment is formed.

EFFECT: this provides not only the possibility of a problem-free placement of the cyclone dust separator assembly in the vacuum cleaner housing, intended, for example, to receive the dust separator assembly with a dust bag, but also the possibility of direct operation of the cyclonic dust separator assembly without the need for any adaptation of the housing cover.
