Description

Air Cleaner {Air Cleaner}

The present invention relates to an air purifier.

An air purifier is a device that filters foreign substances in air existing in a specific space and purifies the air in a specific space by releasing the filtered air. The air purifier may have a structure in which an area in which the suction port is disposed is large to suck air in a wide area and filter the air.

Korean Patent Laid-Open Publication No. KR 10-2017-0140578 discloses an air purifier having a perforated suction port on the circumferential surface of a cylindrical case.

However, in the case of an air purifier having a perforated suction port, since it has a limited opening ratio, if the range of the opening ratio is increased, the suction performance and the air cleaning performance can be expected to be improved.

An object of the present invention is to provide an air purifier with improved suction performance and air cleaning performance by increasing the opening ratio of the suction port.

Another object of the present invention is to provide an air purifier that reduces the burden of the manufacturing process by using a mold of a simple shape.

The problems of the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

In order to achieve the above object, an air purifier according to an embodiment of the present invention is spaced apart in a circumferential direction perpendicular to the vertical direction so that a circumferential surface is formed in a direction perpendicular to the vertical direction, and a suction port is formed on the circumferential surface. A case including a plurality of grill groups, a blowing fan disposed inside the case to flow air introduced through the suction port upward, and a blowing fan disposed inside the case and filtering the air introduced through the suction port Including a filter, each of the plurality of grill groups forms an inlet opening in different directions, and the plurality of grills included in each of the plurality of grill groups extend in the same direction from the inner end to the outer end. Formed, having a stripe shape, a case having a plurality of suction ports spaced apart in the circumferential direction can be manufactured through an injection process.

A direction in which a grill included in one grill group among the plurality of grill groups is disposed forms a right angle or an acute angle with a direction in which the grills of the grill group disposed adjacent to the one grill group are disposed, so that the circumferential surface of the case The direction in which the suction port formed in the opening direction is not formed more than 90 degrees in relation to the suction port formed adjacently. That is, it has a structure in which air does not flow in a direction completely different from the direction in which the circumferential surface faces.

The plurality of grills included in each of the plurality of grill groups are spaced apart in the circumferential direction, and the directions extending from the inner end to the outer end of the grill are arranged in parallel to each other, so that the grills included in the grill group have the same direction. , so that one injection for each grill group is possible.
