20090193769 | Ceiling type air conditioner - There is provided a ceiling type air conditioner including a brush assembly for collecting foreign matters filtered by a filter. The brush assembly includes a brush that contacts the foreign matters filtered by the filter and a main body for collecting the foreign matters separated from the filter to store the foreign matters. Therefore, it is possible to effectively collect and store the foreign matters filtered by the filter in the main body due to the movement of the brush assembly. In addition, since a user does not have to exchange or clean the filter, it is possible to prevent inconvenience from being caused by exchanging or cleaning the filter and to prevent the filter from being contaminated. | 08-06-2009 |
20100107575 | SELF-CLEANING DEVICE OF FILTERING NET OF AIR CONDITIONER - A self-cleaning device of a filtering net of air conditioner is installed on a filtering frame in an air inlet of a dust spiral case of a package air conditioner and is disposed outside the filtering net. A filtering net guide rail with slots is installed on an upper frame and a lower frame. The filtering net is fixed on the filtering net frame by the slots of guide rails. The cleaning device of the filtering net includes a sweeping assembly with a brush, a drive motor fixed on the sweeping assembly, a transmission mechanism connected to the drive motor, a rack group installed on the left and right side of the filtering net, a dust collecting box installed under the filtering net for collecting dust, and a dust exchanging device is disposed between the dust collecting box and the filtering net. The drive motor connected with the transmission mechanism drives the sweeping assembly sliding up and down attached the filtering net along the rack group, thus dust is cleaned by the brush, then dust is put into the dust collecting box through the dust exchanging device. The device is easily loaded and unloaded, and used with less time and labor, the filtering net can be cleaned any time or on time. | 05-06-2010 |
20110011041 | Vacuum Cyclone Dust Collector - A vacuum cyclone dust collector according to the present invention comprises an upper housing through which an absorption hole and a discharging hole are formed and inside which air is inputted and discharged, a lower housing which induces air, which is inputted inside the upper housing through the absorption hole, to be circulated and is connected detachably to the lower part of the upper housing, and air refining part which is arranged rotatably to the upper part of the upper housing with keeping a vacuum state and allows air being inputted through the absorption hole to be circulated inside the upper housing and the lower housing and fine dust and impurities contained in air being inputted through the absorption hole to be dropped downward and refined air without fine dust and impurities to be discharged through the discharging hole. | 01-20-2011 |
20120151885 | AIR FILTER DEVICE AND ELECTRONIC DEVICE - An air filter device includes an air filter that removes dust from air drawn into a device. The air filter includes an air filter surface. A brush including bristles removes dust from the air filter. The brush and the air filter are relatively moved in a direction orthogonal to a longitudinal direction of the brush while distal parts of the bristles of the brush penetrate the air filter surface to remove dust from the air filter. A unit for reducing or eliminating penetration reduces or eliminates penetration of the brush into the air filter when relative movement of the brush and the air filter is stopped. | 06-21-2012 |
20120233971 | DUST COLLECTING APPARATUS HAVING A DUST REMOVING UNIT - A dust collecting apparatus having a dust removing unit. The dust collecting apparatus includes a first cyclone unit which rotates air introduced from outside to separate dust from the air; a second cyclone unit including a second centrifugal separation chamber into which dust discharged from the first cyclone unit is introduced, and second cyclone discharge pipe for passage of air discharged from the second centrifugal separation chamber; a filter assembly including a filter member arranged in the upper portion of the second cyclone unit to separate fine dust from air discharged from the second cyclone unit; and a dust removing unit which separates dust from the filter member, wherein the dust separated from the filter member passes through the second cyclone discharge pipe and is collected in the second centrifugal separation chamber. | 09-20-2012 |

20090113857 | LOW MAINTENANCE AIR CLEANING SYSTEM FOR WELDING CHAMBERS - The present invention relates to a novel enclosure and air filtration design for use with robotic welding stations. It includes a novel frame design, novel air cleaning systems and systems for reducing the frequency of cleaning the air cleaning system. | 05-07-2009 |
20100180556 | DISTRIBUTOR FOR RINSE AIR - The invention relates to an air distribution device for providing rinsing air to a gas cleaner provided with filter bags, said air distribution device comprising: an air distribution member in form of a hollow member; a connection to an air supply means for rinse air, where the air distribution member is a rotatable tube ( | 07-22-2010 |
20110083407 | AIR DISTRIBUTION ARRANGEMENT FOR A DUST COLLECTOR SYSTEM - A dust collector system including a plurality of air filters that are at least partially self-cleaning via a pulsed air system. The dust collector system presents a self-aligning, tool-free assembly for providing the pulsed air. The pulsed air system comprises an air distribution assembly including an air distribution manifold having a plurality of purge pipes and a frame for supporting at least some of the purge pipes, wherein at least two or more of the purge pipes are coupled together in a generally unitary assembly; and a positioning assembly for selectively positioning and removably locking the air distribution manifold in either of a service position or an operational position. | 04-14-2011 |

20080264006 | High aspect ratio and multi-curvature separator, and hybrid air cleaner using the same - An inertial separator includes a main duct having a first half (H | 10-30-2008 |
20090211208 | ROTARY VACUUM APPARATUS FOR AIR SCREEN - A vacuum apparatus rotatable about an axis through a filter screen for continually removing contaminants, which utilizes an asymmetrical vacuum arm supported by a center hub, and large longitudinally extending asymmetrical vacuum orifices in portions of the arm on opposite sides of the hub, operable for removing large elements of debris, trash and the like from the screen. One of the arm portions cleans a radial outer region of the screen, and the other cleans an inner region, the arm portions being generally even in mass for balance. A knife disposed on the screen cleans and cooperates with a brush on the arm for breaking up larger elements of trash. The arm is also manually removable via a snap together vacuum seal joint, for service and cleaning. | 08-27-2009 |
20130055690 | Enhanced air filtration mechanism - A filtration system which uses a frame being a multi-sided tube positioned substantially horizontal. The tube is closed at a first end and supports a multitude of filters which filter the ambient air flowing into the interior of the multi-sided tube. A motor mechanism rotates the multi-sided tube around a horizontal axis while a fan draws air from the second end of said multi-sided tube, thereby pulling the ambient air through the filters. A pulsed air jet is directed at a bottom group of filters and periodically cleans the filters, allowing the debris to fall into a catch basin where an auger pulls the debris away. | 03-07-2013 |
