A dishwasher includes a filter member that is inserted through the lower surface of a tub at a time of replacing the filter member and is applicable regardless of the type of a dishwasher, thereby reducing manufacturing costs and enhancing user convenience. The cylinder-shaped filter member is accommodated entirely in a filter housing, and external air flows into the filter member through the upper end and the lower end of the filter member respectively and then passes through the outer circumferential surface of the filter member, to be filtered, thereby preventing the filter member from being blocked partially and ensuring a sufficient flow rate of air.

A dishwasher includes a filter member having a handle integrally provided at an upper cover of the filter member. The filter member is accommodated in a filter accommodation space of a filter housing, where a movement space of the filter member is larger than the filter member, thereby preventing damage to the filter material or a fall of contaminants into the filter housing effectively, during withdrawal and insertion of the filter member. A separation space defined between the filter housing and the upper cover of the filter member is closed by a gasket, in the state where the filter member is disposed in the filter housing completely, thereby preventing the flow of non-filtered air into the filter housing effectively.

The present disclosure relates to a dust extractor (1) comprising a dust cyclone container (3) comprising a dust inlet (2) leading into the dust cyclone container (3), the dust extractor (1) further comprising a fine filter section (12) adapted to receive at least one fine filter part (15) downstream the dust cyclone container (3). A contaminated side of the fine filter part (15) is adapted to be fluidly connected to the dust cyclone container (3) via an air channel (47) that at least partly is comprised in a lid arrangement (13,14) and runs between a cyclone channel connecting rim (23) and a first fine filter section channel connecting rim (40), when the lid arrangement (13, 14) is positioned over the dust cyclone container (3) and the fine filter section (12). A first lid part (13) is releasably attachable to the dust cyclone container (3) and a second lid part (14) is releasably attachable to the fine filter section (12).

A dust collector apparatus includes a housing, an airflow generation module and a filter. The housing has one side formed at least one intake vent-hole and another side formed of at least one exhaust vent-hole. An inner side of the housing has an airflow channel formed between the intake vent-hole and the exhaust vent-hole. The airflow generation module comprises an airflow drawing unit for drawing an airflow in order to form the airflow channel between the intake vent-hole and the exhaust vent-hole, a control module for controlling the airflow drawing unit, and a power module. The filter is detachably arranged at the intake end and used for filtering dust in the air sucked by the airflow drawing unit. The dust collector apparatus of the present invention allows the dust particles to be properly collected by the filter without secondary scattering, and guides the airflow to be exhausted smoothly.

An air purification system includes a conduit extending between an inlet and an outlet, each in fluid communication with an enclosed environment. Ambient air from the enclosed environment enters the conduit via the inlet and treated air exits the conduit and enters the enclosed environment via the outlet. The system further includes a fibrous filter disposed within the conduit and configured to treat the ambient air thereby generating the treated air, and a renewal unit disposed within the conduit and configured to renew the fibrous filter.

A smoke and dust treatment apparatus for welding, said apparatus comprising a polishing and dust extraction module and a smoke and dust purification module. The polishing and dust extraction module comprises a double-layer dust extraction cover (3), a protective cover (2), an industrial brush (4), a first air guide portion, a second air guide portion (24) and a drive motor (22), the drive motor (22) driving the industrial brush (4) to rotate at high speed to perform polishing. During welding and polishing, a mechanical arm (6) drives the double-layer dust extraction cover (3), and a suction hole (20) of the double-layer dust extraction cover (3) and a suction guide hole (19) on the industrial brush (4) simultaneously take in toxic gas and debris such as iron filings.

An air filtration apparatus includes an airflow powerhead assembly including a fan assembly and a vane assembly, a filter assembly, and a separator chamber housing inside of which the filter assembly is disposed. The separator chamber housing has a chamber inlet at a first axial side and a clean air outlet at a second axial side of the separator chamber housing opposite the first axial side. The filter assembly has a first axial end adjacent the chamber inlet and a second axial end adjacent the clean air outlet. The separator chamber housing includes at least one debris ejection slot extension configured to eject debris from an inner space of the separator chamber housing. The filter assembly includes a debris catch tray disposed at the second axial end, the debris catch tray having a debris ejection slot aligned with the at least one debris ejection slot extension.

Provided is an air cleaner, and more specifically, to an air cleaner in which a filter part using a photocatalyst is formed in a module type to facilitate replacement and cleaning and which includes an insert fan which is disposed inward from a suction port of a casing forming an exterior and including the suction port disposed at one side and a discharge port disposed at the other side, and suctions ambient air, a driving motor provided to be axially detachably coupled to the insert fan in a direction from the discharge port, and a suction unit fixing part in which an accommodation space, into which the insert fan and the driving motor are fixedly inserted in the direction from the suction port toward the discharge port and which is finished by inserting a cover member in the direction from the discharge port.

A portable airborne pathogen control apparatus and system. Aspects of the present disclosure provide for a portable airborne pathogen control apparatus configured to be selectively positioned within an interior room and configured to enable a floor-to-ceiling flow of air within the interior room. The portable airborne pathogen control apparatus may comprise a housing with an air intake disposed at a lower area of a base housing and an air outlet disposed at an upper area of an elongated duct extending from the base housing. A blower fan housed within an interior chamber of the housing may be configured to direct a floor-to-ceiling flow of air through the interior chamber from the air intake to the air outlet. A volume of air directed through the interior chamber of the housing may be disinfected using one or more UV-C emitters and/or cold plasma generator(s) housing in the interior chamber of the housing.

A combination air filter and goggles includes a pair of goggles; an air filter; a tube having a first end attached to the goggles and a second end attached to the air filter; a first strap having two ends attached to the air filter; and a check valve disposed on the goggles. The air filter includes a centrifugal fan, a circuit board, a UV lamp, a filter element, a power supply, a housing, and a cover. Clean air produced by the air filter may flow to inside of the goggles.
