Description

Air Cleaner The present invention relates to an air purifier. Generally, an air purifier is a device that inhales contaminated indoor air and purifies it into clean air by filtering out dust, odor particles, and other contaminants contained in the air. Such an air purifier can purify indoor air by inhaling and purifying the surrounding contaminated air, and then discharging the purified clean air to the outside of the air purifier. Such an air purifier may include an inlet for drawing air into the interior, a blower fan providing airflow to draw air into the inlet, a filter for removing dust, odor particles, and other contaminants contained in the air drawn into the interior, and one or more outlets for discharging the air filtered by the filter. In addition, conventional air purifiers may include multiple filters and multiple blower units to draw in air at different locations and discharge filtered air in different directions. In this regard, Korean Published Patent Application 10-2020-0122941 of LG Electronics Co., Ltd., "Air Purifier" (Patent Document 1), discloses an air purifier comprising a first blower unit that discharges air laterally and a second blower unit that discharges air upwardly and is positioned above the first blower unit. Additionally, Patent Document 1 discloses that each of the first blower unit and the second blower unit includes a filter member and a fan positioned above the filter member. However, Patent Document 1 does not disclose at all that air flows downward inside the air purifier. In other words, since the fans of the first and second blower units of Patent Document 1 are positioned above the filter member, the air filtered by the filter member can only flow upward by the blower force. Therefore, the air purifier of Patent Document 1 has a problem in that the filtered air cannot flow downward inside, and thus the filtered air cannot be discharged toward the floor. In addition, the present applicant’s Korean published patent application 10-2018-0138248 “Air purifier equipped with bidirectional fans using an exhaust path (Patent Document 2)” discloses an air purifier comprising a filter unit for filtering air, a plurality of fans for sucking in filtered air, and an exhaust path for discharging filtered air discharged from the plurality of fans to the side or upward. However, Patent Document 2 does not disclose at all that filtered air flows downward inside the air purifier. In other words, since the multiple fans of the air purifier in Patent Document 2 are configured to discharge the inhaled filtered air towards the side and upward toward the discharge path, the filtered air can only flow upward from the discharge path. Therefore, the air purifier in Patent Document 1 has a problem in that the filtered air cannot flow downward inside, and thus the filtered air cannot be discharged toward the floor.
