The case110formed with the air inlet111and the air outlet112may have a rectangular parallelepiped form, but is not limited thereto.

Further, a material of the case110may be metal or plastic, but is not limited thereto.

Further, the coupling recess113, which may be coupled to the rotating body131, is formed on the lower surface of the case110.

Further, the air inlet111is a passage, through which external air flows into the inside, and the air outlet112is a passage, through which purified air passing through the filter120mounted at the other side of the case110is discharged to the outside.

In the present invention, the filter120may be a roll filter. The filter120is a roll filter, and may include one pair of rollers121and122mounted in an upper portion and a lower portion of an end portion of the other side of the case110, and the filter120may be wound around the rollers121and122.

The roller may include an upper roller121and a lower roller122, and one end of the filter120may be wound around the upper roller121, and the other end of the filter120may be wound around the lower roller122.

Further, the tiller120serves to purify contaminated air, and includes various kinds of filters, such as a high efficiency particulate air (HEPA) tiller providing antibacterial and sterilization functions and removing fine dust.

In the present invention, the support part130includes the rotating body131, which is capable of rotating 360°. The support part130may be coupled to the coupling recess113formed at a point of 5 to 45% of a length of the case110in a direction of the air inlet111at a center of the lower surface of the case110.

When the coupling recess113is formed at a position less than 5% of the length of the case110in the direction of the air inlet111at the center of the lower surface of the case110, the case110may not easily rotate during the rotation according to a wind direction, and when the coupling recess113is formed at a position more than 45% of the length of the case110, a center of gravity is not matched, so that the air purifier100may fall.

Further, a material of the support part130may be metal or plastic, but is not limited thereto.

The rotating body131, which enables the case110to rotate 360°, is formed in the upper portion of the support part130. The rotating body131may be formed of a bearing, but is not limited thereto.

Further, a height of the support part130may be 1 to 30 times of the length of the case110, preferably, 1 to 15 times, and more preferably, 1 to 5 times.

In the present invention, the rudder140adjusts a direction of the air inlet111of the case110according to a wind direction. The rudder140may include a rudder body part141connected to the upper surface of the case110and a rudder wing part142formed at the other side of the rudder body part141.

A portion from one side to the other side of a lower end of the rudder body part141may be connected from the center portion of the case110to the other side of the case110, a height of the rudder body part141may be increased from the center portion of the upper surface of the case110to the other side of the case110, and a length of a lower end of the rudder body part141may be 5 to 50% of a vertical length of the upper surface of the case110.

Further, a curvature of a lower end of one side of the rudder wing part142lacing the upper roller121may be the same as a curvature of the upper roller121, and a distance between the lower end of one side of the wing part142and the upper roller121may be 5 to 20 cm, particularly, 5 to 10 cm.

When the distance is less than 5 cm, friction may be generated between the upper roller121and the rudder wing part142during the rotation of the upper roller121, and when the distance is more than 20 cm, wind passes through a gap between the upper roller121and the rudder wind part142, so that the case110may not rotate.

The rudder wing part142may be formed at the other side of the rudder body part141of the case110in the direction of the air outlet, and may be formed at a forming angle of 90°, which is vertical to the upper surface of the case110, to a forming angle of 180°, which is horizontal to the upper surface of the case110.

When the forming angle of the rudder wing part141is less than 90°, the case110may rotate so that the air inlet111has the same direction as a blowing direction according to a wind direction, and when the forming angle of the rudder wing part141is more than 180°, force by wind is not sufficiently transferred, so that the case110may not rotate.

Further, a shape of the rudder wing part142may be a circle, but is not limited thereto, and the rudder wing part142may be formed from the center portion of the case110to a rear side of the air outlet112in the direction of the air outlet112, and a length of the rudder wing part142may be 50 to 150% of the length of the lower end of the rudder body part141.

When the length of the rudder wing part140formed at the rear side of the air outlet112is less than 50% of the length of the lower end of the rudder body part141, force by wind is not sufficiently transferred, so that the case110may not easily rotate during the rotation according to a wind direction, and when the length of the rudder wing part140formed at the rear side of the air outlet112is more than 150% of the length of the lower end of the rudder body part141, it is difficult to match the center of gravity, so that the case110may not easily rotate during the rotation according to a wind direction.

Further, a material of the rudder140may be metal or plastic, but is not limited thereto.

The air purifier110according to the present invention receives force of wind by the rudder140when wind blows, a direction of the air inlet111formed in the case110faces the wind while the bearing included in the rotating body131rotates.

Then, the wind passes through the filter120mounted to the air outlet112while passing through the inside of the case110, so that fine dust and the like existing in the air are removed, and the air, from which fine dust and the like are removed, is discharged through the air outlet112.

Further, when the filter120is contaminated, the contaminated filter120is wound around the upper roller121or the lower roller122by rotating the rollers121and122and the filter120wound around the upper roller121or the lower roller122is positioned in the air outlet121by rotating the upper roller121or the lower roller122to purify air.
