  • Patent number: 10233877
    Abstract: An apparatus and a method are provided for an air filter cleaning wand for flushing contaminants from an intake air filter of an automobile engine. The air filter cleaning wand comprises a proximal flange, a conduit, and a distal end portion. The proximal flange is configured to receive a nozzle of a water hose. An interior of the conduit is in fluid communication with the proximal flange. The distal end portion comprises a plurality of longitudinally aligned vents in fluid communication with the interior of the conduit. Upon passing water through the water hose and into the conduit, pressurized water streams exit the vents along the distal end portion so as to flush contaminants from the air filter. The air filter cleaning wand advantageously is comprised of a material which is sufficiently durable and temperature resistant to retain its configuration during operation when coupled to pressurized water sources.

  • Patent number: 10227958
    Abstract: A pre-filter assembly for a vehicle arranged with an aspiration duct extending between the pre-filter and a fan of the vehicle. A variable valve element is provided as part of the aspiration duct adjacent the fan, such that the aspiration rate through the duct can be controlled by appropriate variation of the valve element, to control the rate of airflow drawn through the aspiration duct by the fan. This allows for the aspiration rate of the pre-filter to be at least partly independent of the flow rate of the fan, without the need for an additional motor-driven blower unit.

  • Patent number: 10222080
    Abstract: An air purifier capable of reducing time required for purification of a room without giving a feeling of discomfort to a human in the room is provided. During operation of an air purifier 1, air drawn from an inlet 3 into a casing 2 is purified by a purification device 7 and the air is blown to the outside from an outlet 4. If a user of the air purifier 1 selects a particular operation mode in which the user designates an air volume, a control device 12 performs air volume maintaining control. In the air volume maintaining control, with a volume of air blown out from the outlet 4 by the air blowing device 5 maintained constant, a speed of the air is varied by an air guiding device 8 based on a status of pollutant detection. Alternatively, the speed of the air is varied by the air guiding device 8 and the volume of the air is varied by the air blowing device 5.

  • Patent number: 10222077
    Abstract: A dust removing apparatus is provided. An air blower performs air blowing in a space. A processor determines a first period in which a user is absent in the space. An air sucker collects dust by performing air suction from the space during the first period. A sensor measures an amount of dust collected by performing the air suction in the space during the first period. The processor determines whether or not a usage status of the dust removing apparatus in the space is appropriate based on a comparison between the measured amount of dust collected in the first period and an estimated amount of dust, which is estimated to be collected under a usage condition in which the user is absent in the space, and outputs information indicating whether or not a usage status of the dust removing apparatus is appropriate based on a result of the comparison.

  • Patent number: 10212914
    Abstract: Heat exchangers extract heat from an air stream and deliver the heat to another airstream. The heat exchangers are modified with a filtration system to allow the heat exchanger to effectively run within the poultry house environment. The poultry house is retrofitted with at least four flat-plate cross-flow heat exchangers. The heat exchangers operate to meet at least the minimum ventilation rates for the young birds. As birds grow, heat exchangers operate in conjunction with building exhaust fans for ventilation needs. Multiple heat exchangers are located throughout the house to provide appropriate ventilation.

  • Patent number: 10213718
    Abstract: Various embodiments relate to an air intake duct. The duct includes louvers forming an air inlet to a housing. Each louver includes an inlet section and an angled section, the angled section inclined with respect to the inlet section. The duct includes the housing positioned downstream of the louvers in an air flow direction. The housing includes a drain configured to permit separated water from an intake air passing through the louvers and into the housing to be drained from the housing. The duct includes an inner inlet duct that provides the intake air to a component. The inner inlet duct extends into the housing and positioned downstream of the louvers in the air flow direction. The inlet duct extends above the drain by a distance thereby forming a well in the housing between a top of the inner inlet duct and the drain.

  • Patent number: 10201774
    Abstract: A bag house filter bag is suspended vertically from a separable hanger. The filter bag has a closure at the top, which is constructed by a series of tucks and folds. The closure also provides a support loop for engagement with the hanger. The filter bag is constructed mainly of woven fabric formed into a cylinder. The folding and stitching pattern of the fabric at the top end enables the bag to transition from linear at the site of the support loop to cylindrical with an even distribution of stress on the fabric. The hanger includes a cross member and a surrounding tube to reduce specific stress on the fabric. The hanger has a removable joint opening clasp at one end of the cross member to enable rapid insertion and removal of the hanger from within the suspension tube without contact, removal or other disturbance of the filter bag.
