Description

Air Cleaner {Air Cleaner}

The present invention relates to an air purifier, and more particularly, to an air purifier in which a circulator for controlling a flow direction of clean air is disposed on the upper side.

An air purifier is a device for reducing dust or bacteria in the air of a certain space by filtering and discharging the air inside the space. The air purifier filters out foreign substances through the air flow in the corresponding space, and discharges the air from which the foreign substances are removed.

In order to suck air in a wide range of the corresponding space and discharge the filtered air, an intake port is formed on the circumferential surface of the cylindrical case and a structure for discharging the filtered air upward can be disclosed. However, in order to discharge the filtered air to a remote area of the corresponding space, a device for converting a separate flow to the upper side through which the filtered air is discharged may be provided to discharge the filtered air to a wide area of the indoor space.

Korean Patent Laid-Open No. 10-2018-0000121 discloses a blower for flowing air from the lower circumferential surface to the upper side, and a flow conversion device disposed on the upper side of the blower to convert the flow of air discharged to the upper side, have.

The flow conversion device has a structure connected to the blower, and has a closed structure, so an axial fan having an annular suction port is used. The flow conversion device to which the axial fan is applied may perform a function of circulating air in a specific space by discharging air of a desired air volume by adjusting the number of rotations. However, when the discharge passage area is reduced, the air volume may be reduced, and when passing through the grill without a separate vane, there is a problem that energy loss of the flow may occur.

Contrary to the prior literature, in the case of applying the flow fan and the vane structure to the flow conversion device, as the motor is disposed above the blower fan, it may be difficult for the user to separate and manage the blower fan from the flow conversion device.
