Abstract: According to an embodiment of the present disclosure, a ceiling fan includes a shaft coupled to a ceiling or a wall surface, a housing cover provided at a central axis thereof with a shaft and receiving a motor assembly and an electronic unit, and a blade coupled to the housing cover. The electronic unit is provided in a multi-stage.

Abstract: A ceiling fan may include a shaft coupled to a ceiling, a cover to surround the shaft, a main blade having a blade hole which is a space open inward, and a sub-blade positioned in the blade hole. The sub-blade is disposed to have an angle of attack different from an angle of attack of the main blade. The ceiling fan may resolve a red zone of the air flow and may improve air volume and the flow rate due to the dual blades.

Abstract: An air cleaner is provided. The air cleaner may include a circular filter assembly, in which a plurality of filters may be stacked, a circular rear or first case including a mount sleeve, on which the filter assembly may be mounted, a circular middle or second case, on which a discharge grille may be disposed, the second case being coupled to a front or first surface of the first case, a circular front or third case coupled to a front or first surface of the second case, and a circular panel attached to a surface of the third case. The filter assembly may include a first filter, a second filter disposed at a side of the first filter to accommodate the first filter, and a third filter disposed at a side of the second filter to accommodate the second filter. Edges of surfaces of the first to third filters may be flush with each other.

Abstract: An air cleaner is provided. The air cleaner may include a filter assembly having a plurality of stacked filters, a first case including a filter mount sleeve having the filter assembly mounted thereon, a second case coupled to a first surface of the first case and having a discharge grille disposed on a first side thereof, a support leg disposed on a second side of the second case corresponding to an opposite side of the discharge grille, a third case coupled to a first surface of the second case, and a first panel attached to a first surface of the third case. When the filter assembly, the first case, the second case, the third case, and the first panel are coupled to each other, the air cleaner may have a cylindrical exterior. The discharge grille may extend by a predetermined distance along an upper circumferential surface of the second case.
