air purifier

Abstract

The present invention relates to an air cleaner capable of stably cleaning the air in the entire room by properly controlling the airflow in a room under various installation environments. The air cleaner (1) is equipped with a casing (2), an air inlet (4), an air outlet (5), a fan unit (6), a deodorizing filter (10), a dust collection filter (11), a movable louver ( 12), drive unit (13), shaking head mechanism (14), internal detection device (15), external detection device (16), control device (18), etc. The wind direction of the air blown out from the air outlet (5) is changed between the front and the top and in the vertical direction by the movable louver (12), and is changed in the left and right direction by the oscillating mechanism (14). An external detection device (16) detects indoor information including at least a distance from a wall of a room. Moreover, the control device (18) controls at least one air supply parameter in the wind direction, air volume and wind speed of the blown air based on the detection result of the indoor information, so that the blown air is formed and returned to the air cleaner (1 ) recirculating airflow at the position.

Description

technical field [0001] The present invention relates to an air cleaner having a function of purifying sucked air and blowing out the purified air. Background technique [0002] As a related art, for example, as described in Patent Document 1, there is known an air cleaner provided with a movable louver that swings in the horizontal direction. Conventional air cleaners, for example, are configured to detect air pollutants in various directions by sensors while swinging louvers left and right in order to efficiently clean air in a wide room. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2006-57919 [0004] In the prior art described above, the air in the entire room is cleaned by swinging the louvers from side to side. However, depending on the installation environment of the air cleaner (such as the area of ​​the room where the air cleaner is installed, the arrangement of the air cleaner in the room, furniture, etc.), it may be difficult to circulate the air to ...

Problems solved by technology

However, depending on the installation environment of the air cleaner (such as the area of ​​the room where the air cleaner is installed, the arrangement of the air cleaner in the room, furniture, etc.), it may be difficult to circulate the air to every part of the room even if the louvers are swung from side to side. corner

That is, in the prior art, the purification state of the indoor air is greatly affected by the installation environment of the air cleaner, so there is a problem that it is difficult to stably purify the air in the entire room.
