Abstract

An air cleaner is provided that may include at least one blowing device including a main fan that generates air flow and a first discharge outlet through which air passing through the main fan is discharged; a flow controller movably provided at one side of the at least one blowing device, the flow controller including a sub-fan that generates air flow and a discharge grill through which air passing through the sub-fan is discharged; and a display provided in the discharge grill, the display device displaying operation information.

First claim

What is claimed is:

1 . An air cleaner, comprising:
at least one blowing device including a main fan that generates air flow and a first discharge outlet through which air passing through the main fan is discharged; a flow controller movably provided at one side of the at least one blowing device, the flow controller including a sub-fan that generates air flow and a discharge grill through which air passing through the sub-fan is discharged; and a display provided in the discharge grill, the display displaying operation information.

2 . The air cleaner of claim 1 , wherein the discharge grill includes:
a depression portion formed at a center portion of the discharge grill; a plurality of grill portions that extends to the outside in a radial direction from the depression portion; and a second discharge outlet formed between the plurality of grill portions, the second discharge outlet allowing air to be discharged therefrom.

3 . The air cleaner of claim 2 , wherein the display is provided at the depression portion.

4 . The air cleaner of claim 1 , wherein the display includes:
a display printed circuit board (PCB) on which a plurality of illumination sources is provided; and a reflector coupled to one side of the display PCB, the reflector concentrating light irradiated from the plurality of illumination sources.

5 . The air cleaner of claim 4 , wherein the plurality of illumination sources include:
a first illumination source that displays operation information of the air cleaner on a display screen; and a second illumination source that implements a rim of the display.

6 . The air cleaner of claim 5 , wherein the display PCB includes:
a main body front surface on which the first illumination source is provided; and a main body rear surface on which the second illumination source is provided.

7 . The air cleaner of claim 5 , wherein the display further includes a diffusing plate configured to surround the display PCB, the diffusing plate guiding light irradiated from the second illumination source toward the rim of the display screen.

8 . The air cleaner of claim 7 , wherein the display PCB has a circular shape, and the diffusing plate has a ring shape.

9 . The air cleaner of claim 7 , wherein the diffusing plate includes:
a plate main body supported by the discharge grill; and an illumination accommodating portion that protrudes from an inner circumferential surface of the plate main body to allow the second illumination source to be provided therein.

10 . The air cleaner of claim 9 , wherein the plate main body and the illumination accommodating portion are integrally formed.

11 . The air cleaner of claim 9 , wherein at least one of the plate main body or the illumination accommodating portion is made of a translucent material through which refraction or diffusion of light is performed.

12 . The air cleaner of claim 9 , wherein the illumination accommodating portion includes:
first and second side surfaces that extend to an inside in a radial direction from the inner circumferential surface of the plate main body; a third side surface that connects the first and second side surfaces; and a fourth side surface provided at a lower side of the first and second side surfaces.

13 . The air cleaner of claim 12 , wherein the first to fourth side surfaces and the inner circumferential surface of the plate main body define an accommodating space into which the second illumination source is inserted.

14 . The air cleaner of claim 1 , wherein the discharge grill includes:
a grill outer wall; a grill inner wall provided inside of the grill outer wall; a plurality of grill portions that extends from the grill outer wall to the grill inner wall; and a second discharge outlet formed between the plurality of grill portions.

15 . The air cleaner of claim 14 , wherein the display includes a display printed circuit board (PCB) supported by the grill inner wall, wherein a plurality of illumination sources is provided on the display PCB.

16 . The air cleaner of claim 15 , wherein the display includes:
a display cover that supports an outside of the display PCB; and a cover film attached to the display cover to allow a portion of light transferred from the display PCB to be transmitted therethrough.

17 . The air cleaner of claim 1 , wherein the flow controller includes:
a first guide that guides rotation of the flow controller in the first direction; and a second guide that guides rotation of the flow controller in a second direction.

18 . The air cleaner of claim 17 , wherein each of the first guide and second guides includes a gear and a gear motor.

19 . The air cleaner of claim 1 , wherein the flow controller is provided at an upper side of the at least one blowing device.

20 . The air cleaner of claim 19 , wherein the display forms an upper surface of the flow controller.
