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;

a light source provided within the dividing plate;

a diffuser disposed at an outer side of the light source in a radial direction and extending in the radial direction, the diffuser being configured to transfer light emitted from the light source; and

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

2. The air cleaner according to claim 1, further including at least one reflecting sheet provided at an upper side or a lower side of the diffuser, wherein the at least one reflecting sheet reflects the light emitted from the light source to the diffuser, and wherein the at least one reflecting sheet is made of an opaque material.

3. The air cleaner according to claim 2, wherein the opaque material includes polyethylene phthalate (PET), stainless steel, brass, or aluminum.

4. The air cleaner according to claim 3, wherein the diffuser is made of a translucent material.

5. The air cleaner according to claim 4, wherein the translucent material includes acrylic or polymethyl methacrylate resin (PMMA).

6. The air cleaner according to claim 1, further including a diffusion sheet provided on an outer circumferential surface of the diffuser, wherein the diffusion sheet scatters the light transmitted through the diffuser, and wherein the diffusion sheet is made of an opaque material or a translucent material.

7. The air cleaner according to claim 6, wherein the opaque material or translucent material includes polyethylene phthalate (PET) or polycarbonate material.

8. The air cleaner according to claim 7, wherein the diffuser is made of a transparent material.

9. The air cleaner according to claim 8, wherein the transparent material includes acrylonitrile butadiene styrene (ABS).

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

11. The air cleaner according to claim 10, wherein the plurality of colors includes:

green which indicates that the air cleanliness of the indoor space is in a high state,

yellow which indicates that the air cleanliness of the indoor space is in a medium state, and

red which indicates that the air cleanliness of the indoor space is in a low state.

12. 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;

a light source provided within the dividing plate;

a diffuser provided adjacent to the light source in a radial direction and extending in the radial direction, the diffuser being configured to transfer light emitted from the light source;

a display provided at an outer circumferential edge of the diffuser the display being configured to display the transferred light; and

at least one reflecting sheet provided at an upper side or a lower side of the diffuser, wherein the at least one reflecting sheet reflects the light emitted from the light source to the diffuser, and wherein the at east one reflecting sheet is made of an opaque material.

13. The air cleaner according to claim 12, wherein the opaque material includes polyethylene phthalate (PET), stainless steel, brass, or aluminum.

14. The air cleaner according to claim 13, wherein the diffuser is made of a translucent material.

15. The air cleaner according to claim 14, wherein the translucent material includes acrylic or polymethyl methacrylate resin (PMMA).

16. The air cleaner according to claim 12, further including a diffusion sheet provided on an cuter circumferential surface of the diffuser, wherein the diffusion sheet scatters the light transmitted through the diffuser, and wherein the diffusion sheet is made of an opaque material or a translucent material.

17. The air cleaner according to claim 16, wherein the diffuser is made of a transparent material.

18. 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;

a light source provided within the dividing plate;

a diffuser provided adjacent to the light source in a radial direction and extending in the radial direction, the diffuser being configured to transfer light emitted from the light source; and

a display provided at an outer circumferential edge of the diffuser, the display being configured to display the transferred light, wherein the light source includes a light emitting diode (LED) that outputs a plurality of colors which indicates a level of air cleanliness in an indoor space.

19. The air cleaner according to claim 18, wherein the plurality of colors includes:

green which indicates that the air cleanliness of the indoor space is in high state,

yellow which indicates that the air cleanliness of the indoor space is in a medium state, and

red which indicates that the air cleanliness of the indoor space is in a low state.
