Description
Technical Field
The present invention relates to an air cleaner, and more particularly, to an air cleaner provided with an air direction adjusting device.
Background
An air cleaner is a device that reduces dust, bacteria, and the like in air in a predetermined space by filtering and discharging the air in the space. The air purifier filters foreign matters through air flow in the corresponding space and spits out the air with the foreign matters removed.
A structure may be disclosed in which a suction port is formed at an outer circumferential surface of a cylindrical housing and filtered air is discharged to an upper side to suck air in a wide range in a corresponding space and to discharge the filtered air. However, in order to discharge the filtered air to a distant area within the corresponding space, an additional device for converting the flow may be provided at an upper side from which the filtered air is discharged, whereby the filtered air may be discharged to a large area of the indoor space.
Korean laid-open patent No. 10-2018-0000121 discloses an air blowing device that blows air from a lower outer circumferential surface to an upper side, and a flow switching device that is disposed above the air blowing device and switches the flow of air discharged to the upper side. However, in the above structure, there is a problem in that a range in which the rotation angle of the flow conversion device can be changed in the up-down direction is limited.
In addition, when the range of movement of the member for changing the angle of the flow switching device is increased, if a gear box for increasing the gear ratio is used, there is a problem that the driving portion becomes large. In addition, since the usable driving angle is determined according to the position of the gear, the maximum driving angle is limited due to the driving part space, and there is a problem in that the purified air cannot be blown to various angles.

Referring to fig. 1 to 2, the first air blowing device 100 and the second air blowing device 200 may be arranged in the vertical direction. The second air blowing device 200 may be disposed above the first air blowing device 100.
The air purifier 10 includes a housing 101, 201 for forming an external appearance. The housing 101, 201 includes: a first casing 101 forming an external appearance of the first air blowing device 100; and a second casing 201 forming an external appearance of the second air blowing device 200.
The second housing 201 may be cylindrical. The second housing 201 may be constructed such that the diameter of the upper portion thereof is smaller than that of the lower portion thereof.
A second suction port 202 for sucking air is formed in the second housing 201. The second suction port 202 communicates the inside and the outside of the second housing 201. The second suction port 202 is formed in plural. A plurality of second suction ports 202 may be formed on an outer circumferential surface of the second housing 201, and a second discharge port 301 opened upward may be formed on the second housing 201.
