  • Publication number: 20220042714
    Abstract: An air cleaner is provided that includes: a body housing having an air inlet and a filter discharge outlet; a fan module provided within the body housing; a filter supply module provided within the body housing and configured to provide a filter sheet; a filter transportation module configured to transport the filter sheet from the filter supply module such that the filter sheet passes by the air inlet and is discharged at the filter discharge outlet; and a cutting module configured to cut the filter sheet. The filter transportation module includes: a drive supply roller and a driven supply roller; drive and driven discharge rollers that are positioned a distance apart toward the filter discharge sides, respectively, of the two supply rollers; a first roller drive motor configured to drive the drive supply roller; and a second roller drive motor configured to drive the drive discharge roller.

  • Publication number: 20210121813
    Abstract: An air cleaner includes a case, an air inlet, an air outlet, a grill covering the air inlet to filter airborne oil droplets, a fan to suction air through the air inlet and discharge air out of the air outlet, a roll filter provided between the grill and the fan to filter oil mist, and a filter roller to cut the roll filter. The roll filter includes a roller and a filter sheet wound around the roller, and the filter sheet may be unwound to extend behind the grill. When the filter sheet becomes dirty, the roll filter is further unwound so that a clean section is provided behind the grill, and the filter cutter may cut off the dirty section. During cutting, a clamp holds down the filter sheet. The case includes a slit through which the dirty section of the filter sheet passes for discarding.

  • Publication number: 20210123604
    Abstract: A kitchen hood has a first housing and a second housing that slides into and out of the first housing to adjust a length of the kitchen hood. The first housing has a fan to suction air, an outlet, and an air quality sensor assembly to continuously detect air quality in a kitchen. The second housing has an inlet and suction grill through which air is suctioned, a steam cleaning assembly to automatically steam clean an interior of the kitchen hood, and a height sensing assembly to sense a height of cookware seated on a cooktop surface below the second housing. The kitchen hood may be lengthened or shortened based on the sensed height of the cookware, and a speed of the fan and the height of the kitchen hood may be automatically adjusted based on detections by the air quality sensor assembly.
