Abstract

An air cleaner is provided that may include a first air cleaning module having a first fan that generates air flow from a first suction inlet toward a first discharge outlet; a second air cleaning module having a second fan that generates air flow from a second suction inlet toward a second discharge outlet; a dividing plate provided between the first air cleaning module and the second air cleaning module; and a display provided at inside of the dividing plate and in which a light source is provided.

First claim

What is claimed is:

1. An air cleaner, comprising:
a first air cleaning module having a first fan;
a second air cleaning module disposed above the first air cleaning module, the second air cleaning module including a second fan;
a dividing plate provided between the first air cleaning module and the second air cleaning module, the dividing plate including a first plate that extends upwardly and radially from the first air cleaning module, and a second plate disposed above the first plate that extends downwardly and radially from the second air cleaning module, wherein circumferential edges of the first and second plates are configured to converge with each other;
a light source disposed between the first plate and the second plate; and
a diffuser disposed between the first and second plates, the diffuser being configured to transfer light emitted from the light source; wherein the diffuser includes a display provided at an outer circumferential edge of the diffuser configured to emit the light from the light source.

2. The air cleaner according to claim 1 , further including a plurality of reflecting sheets, the plurality of reflecting sheets including:
a first reflecting sheet provided on an upper side of the diffuser; and
a second reflecting sheet provided on a lower side of the diffuser.

3. The air cleaner according to claim 2 , wherein the
first plate includes a first sheet support that contacts the second reflecting sheet, the first sheet support being configured to protrude upward from an upper surface of the first plate; and
the second plate includes a second sheet support that contacts the first reflecting sheet, the second sheet support being configured to protrude downward from a lower surface of the second plate.

4. The air cleaner according to claim 2 , wherein the first and second reflecting sheets cover a top and bottom of the diffuser.

5. The air cleaner according to claim 4 , wherein each of the first and second sheets has a cross-sectional area that gradually increases from a portion disposed adjacent the light source toward an outer circumferential edge of the first and second reflecting sheets in a radial direction.

6. The air cleaner according to claim 2 , wherein the diffuser is made of a translucent material, and wherein at least one of the first and second reflecting sheets is made of an opaque material.

7. The air cleaner according to claim 6 , wherein the at least one of the first and second reflecting sheets is made of polyethylene phthalate (PET), stainless steel, brass, or aluminum.

8. The air cleaner according to claim 6 , wherein the diffuser is made of acrylic or polymethyl methacrylate resin (PMMA).

9. The air cleaner according to claim 1 , wherein an end of the diffuser is interposed between an end of the first plate and an end of the second plate.

10. The air cleaner according to claim 9 , wherein the end of the diffuser, the end of the first plate and the end of the second plate are aligned in a vertical direction.

11. The air cleaner according to claim 1 , wherein the light source includes a light emitting diode (LED), to output a plurality of colors which indicates a level of an air cleanliness degree of an indoor space.

12. The air cleaner according to claim 11 , wherein the plurality of colors includes:
a green color which indicates that the air cleanliness degree of the indoor space is in a high state,
a yellow color which indicates that the air cleanliness degree of the indoor space is in a medium state, and
a red color which indicates that the air cleanliness degree of the indoor space is in a low state.

13. The air cleaner according to claim 11 , wherein an end of the diffuser outputs of the plurality of colors.

14. The air cleaner according to claim 1 , wherein the diffuser is configured to be extended in a radial direction between the first and the second plates from a portion adjacent the light source toward an outer circumferential edge of the first and second plates.

15. The air cleaner according to claim 14 , wherein a thickness of the diffuser gradually decreasing from the portion adjacent the light source toward the outer circumferential edge of the first and second plates.

16. The air cleaner according to claim 14 , wherein a cross-sectional area of the diffuser gradually increasing from the portion adjacent the light source toward the outer circumferential edge of the first and second plates.
