Abstract:
1. An air purifier comprising: a housing having an air inlet port and an air outlet port; a centrifugal fan substantially centered in the housing, the centrifugal fan having a rotary shaft extending in a depth direction of the air purifier and a fan inlet port that faces frontward in the air purifier such that suctioned by the centrifugal fan via the fan inlet port is blown out from the centrifugal fan in a direction perpendicular to the rotary shaft of the centrifugal fan; and an air purifying filter aligned with the centrifugal fan along the direction perpendicular to the rotary shaft of the centrifugal fan, the air inlet port of the housing being disposed in front of the centrifugal fan so as to communicate with the fan inlet port of the centrifugal fan such that air is suctioned into the air purifier via the air inlet port by rotation of the centrifugal fan, and the air outlet port of the housing being arranged relative to the air purifying filter such that air purified by the air purifying filter is blown out of the air purifier through the air outlet port, the air purifying filter including parts each arranged in one of at least two portions selected from a left portion, a right portion, and an upper portion in the housing, and the air outlet port includes parts each disposed on one of at least two of a left side, a right side, and an upper side of the housing corresponding to the at least two portions in the housing where the air purifying filter is arranged.
