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.

Claims

1. An air cleaner, comprising:

a first air cleaning module having a first fan;

a second air cleaning module disposed at an upper side of 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 and a second plate provided at an upper side of the first plate;

a diffuser disposed between the first and the second plates;

a light source disposed at a side of the diffuser, the light source emitting light towards the diffuser; and

a display provided at at least a portion of an outer circumferential surface of the diffuser, the display being configured to display light transferred from the diffuser.

2. The air cleaner according to claim 1, wherein the display is disposed between the first and the second plates.

3. The air cleaner according to claim 2, wherein an end portion of the diffuser includes the display.

4. The air cleaner according to claim 1, wherein the first plate includes:

a plate inner wall having a substantially annular shape; and

a plate outer wall that surrounds the plate inner wall.

5. The air cleaner according to claim 4, further including a device mount on which the light source is mounted, wherein the device mount is provided at an upper surface of the plate outer wall.

6. The air cleaner according to claim 5, wherein an outer circumferential surface of the device mount projects in a radial direction farther than an outer circumferential surface of the plate outer wall.

7. The air cleaner according to claim 1, wherein the diffuser extends outward in a radial direction from the light source.

8. The air cleaner according to claim 4, wherein the diffuser includes a first end disposed between a second end of the plate outer wall and a third end of the second plate, and wherein the first end of the diffuser includes an outer circumferential surface of the diffuser.

9. The air cleaner according to claim 1, further including a reflecting sheet provided at a side of the diffuser, wherein the reflecting sheet reflects the light in order to concentrate the light which is diffused through a diffusion portion at an outer circumferential surface of the dividing plate, and wherein the reflecting sheet is made of polyethylene phthalate (PET), stainless steel, brass, or aluminum.

10. The air cleaner according to claim 9, wherein the reflecting sheet includes:

a first reflecting sheet, provided at an upper side of the diffusion portion; and

a second reflecting sheet provided at a lower side of the diffusion portion.

11. An air cleaner, comprising:

a first air cleaning module having a first fan;

a second air cleaning module provided at an upper side of 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 and a second plate provided at an upper side of the first plate;

a diffuser disposed between the first and the second plates;

a light source disposed at a side of the diffuser, the light source emitting light towards the diffuser; and

a display configured to display light transferred from the diffuser, wherein an end portion of the diffuser includes the display.

12. The air cleaner according to claim 11, wherein the first plate includes:

a plate inner wall having a substantially annular shape; and

a plate outer wall that surrounds the plate inner wall.

13. The air cleaner according to claim 12, further including a device mount on which the light source is mounted, wherein the device mount is provided at an upper surface of the plate outer wall.

14. The air cleaner according to claim 13, wherein an outer circumferential surface of the device mount projects in a radial direction farther than an outer circumferential surface of the plate outer wall.

15. An air cleaner, comprising:

a first air cleaning module having a first fan;

a second air cleaning module provided at an upper side of 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 and a second plate provided at an upper side of the first plate;

a diffuser disposed between the first and the second plates;

a light source disposed at a side of the diffuser, the light source emitting light towards the diffuser;

a display configured to display light transferred from the diffuser; and

a reflecting sheet provided at a side of the diffuser, wherein the reflecting sheet reflects the light in order to concentrate the light which is diffused through a diffusion portion at an outer circumferential surface of the dividing plate, and wherein the reflecting sheet includes;

a first reflecting sheet, provided at an upper side of the diffuser; and

a second reflecting sheet provided at a lower side of the diffuser.
