Patent number: 9015897Abstract: There is provided a dust detection system for a vacuum cleaner comprising a dust separation chamber (20) of cyclone type and having a separate dustbin (30) for collecting separated dust. The dust separation chamber is adapted to provide a generally cyclonic airflow for separating dust from a dust laden air stream, and is at a bottom (25) of the dust separation chamber connected via an outlet (22) to the dustbin. The dust detection system further comprises an emitter (41) positioned to emit an electromagnetic signal into the dust separation chamber during operation of the vacuum cleaner, and a receiver (42) positioned to receive the electromagnetic signal. The inventive concept is based on an understanding that when the dustbin becomes full, dust accumulates at the bottom of the dust separation chamber, i.e. stays rotating at the bottom, since it cannot enter the dustbin.Type: GrantFiled: June 28, 2011Date of Patent: April 28, 2015Assignee: Aktiebolaget ElectroluxInventors: Stefan Jonsson, Fredrik Sjöberg

Patent number: 8997310Abstract: A vacuum cleaner dirt collection assembly having a housing, an air inlet and air outlet connected to the housing and a cyclone chamber inside the housing. The cyclone chamber has top and bottom walls, and an outer wall joining the top and bottom walls to form a generally enclosed space. The outer wall has a helical guide channel extending radially outward from the adjacent portion of the outer wall. An inner wall, located inside the enclosed space, has a generally cylindrical or frustroconical surface having one or more openings fluidly connecting the enclosed space to the air outlet. A separator plate is located inside the enclosed space at a location between the top and bottom walls. The separator plate extends towards the outer wall and is spaced from the outer wall by a gap.Type: GrantFiled: October 12, 2012Date of Patent: April 7, 2015Assignee: Electrolux Home Care Products, Inc.Inventors: Donald Joseph Davidshofer, Gregory James Kowalski, John Curtis Morphey

Patent number: 8991004Abstract: A cyclone separator for a suction cleaning appliance is provided, including a separating container for separating cleaning liquid drawn in by suction, with an inlet through which suction air and cleaning liquid can be drawn by suction into an interior of the separating container, thereby forming a cyclone, a suction extraction line extending into the interior and connectable to a suction unit, with an outlet through which suction air can be drawn out of the interior, and a partition wall shielding the outlet from cleaning liquid, a space being provided between an inner wall of the separating container and the partition wall. The cyclone separator can include at least one transfer element arranged between the partition wall and the inner wall for transferring cleaning liquid from the partition wall to the inner wall, the transfer element bridging the space except for a maximum remaining space of 2 millimeters.Type: GrantFiled: September 4, 2013Date of Patent: March 31, 2015Assignee: Alfred Kärcher GmbH & Co. KGInventors: Yunus Demirtas, Juergen Gassmann, Ronald Schwarz

Patent number: 8984712Abstract: A cyclone separation device (102, 202) and a cyclone vacuum cleaner (100, 200) mounted with the device. A first cyclone separation unit in the cyclone separation device (102, 202) comprises a dust bucket (10) and a mesh filter (7) with air holes (7a). Airflow enters the first cyclone separation unit to undergo first gas-solid separation. The airflow after the separation enters a second cyclone separation unit through the air holes (7a) of the mesh filter (7). A filter in the second cyclone separation unit comprises a plurality of cyclone barrels (31). An upper end and a lower end of the cyclone barrel (31) are open. A first air inlet (31a) and a second air inlet (31b) are disposed on a side wall of the cyclone barrel (31). The airflow (41a, 41b) after the gas-solid separation enters the first air inlet (31a) and the second air inlet (31b) through a first airflow passage and a second airflow passage respectively, is mixed in the cyclone barrel (31), and then undergoes second gas-solid separation.Type: GrantFiled: December 23, 2011Date of Patent: March 24, 2015Assignee: Ecovacs Robotics (Suzhou) Co., Ltd.Inventor: Zhongmei Peng

Patent number: 8978200Abstract: A latch mechanism for a dirt cup of a vacuum cleaner. The latch mechanism can include a first sloped portion provided on a mounting structure for receiving a dirt cup and a filter housing in supporting relationship to the vacuum cleaner and a second sloped portion on the filter housing corresponding to the first sloped portion. Movement of the filter housing in a first direction relative to the mounting structure as the first and second sloped portions bear against each other results in the movement of the filter housing, and thus the dirt cup, in a second direction transverse to the first direction relative to the mounting structure.Type: GrantFiled: July 26, 2011Date of Patent: March 17, 2015Assignee: BISSELL Homecare, Inc.Inventors: Kenneth M.
