Abstract

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes an air clean module receiving external air and performing filtration on the entered external air to generate filtered air, an air wash module disposed at an upper part of the air clean module, receiving filtered air from the air clean module, and performing humidification on the filtered air, a dust sensor disposed on at least one of the air clean module or the air wash module and detecting a dust concentration of external air, and a lighting module disposed on at least one of the air clean module or the air wash module and emitting light as a color classified according to a dust concentration detected from the dust sensor.

First claim

What is claimed is:

1. A humidification and air cleaning apparatus comprising:
an air clean module to receive external air to filter the entered external air;
an air wash module disposed on the air clean module to humidify the filtered air;
a dust sensor disposed on at least one of the air clean module or the air wash module to detect a dust concentration of external air; and
a lighting module disposed on at least one of the air clean module or the air wash module to emit light as a color classified according to a dust concentration detected by the dust sensor,
wherein the lighting module comprises:
a printed circuit board,
a first light emitting member disposed at one side surface of the printed circuit board and a second light emitting member disposed at the other side surface of the printed circuit board, and
a diffusion member having one end facing the first light emitting member and the other end facing the second light emitting member.

2. The humidification and air cleaning apparatus of claim 1 , wherein the lighting module is disposed along an outer side surface of the air clean module or the air wash module, and emits light in all directions of a circumference of the air clean module or the air wash module.

3. The humidification and air cleaning apparatus of claim 1 , wherein the diffusion member is formed in a ring shape.

4. The humidification and air cleaning apparatus of claim 1 , wherein a portion of the diffusion member is cut off to form a separation part, and the first light emitting member and the second light emitting member are disposed at the separation part.

5. The humidification and air cleaning apparatus of claim 4 , wherein the first light emitting member faces the one end of the diffusion member and emits light to the one end of the diffusion member to incident light to an inside of the diffusion member.

6. The humidification and air cleaning apparatus of claim 4 , wherein the second light emitting member faces the other end of the diffusion member and emits light to the other end of the diffusion member to incident light to an inside of the diffusion member.

7. The humidification and air cleaning apparatus of claim 1 , wherein the printed circuit board is disposed vertically and the first light emitting member and the second light emitting member are disposed horizontally.

8. The humidification and air cleaning apparatus of claim 1 , wherein the first light emitting member and the second light emitting member are disposed in an opposite direction.

9. The humidification and air cleaning apparatus of claim 1 , wherein the diffusion member further comprises a bracket fixed to the air clean module or the air wash module.

10. The humidification and air cleaning apparatus of claim 1 , wherein the air wash module comprises:
a visual body formed of a transparent material; and
an installation part formed at the visual body,
wherein the lighting module installed at the installation part, and light emitted from the lighting module is diffused to an outside through the visual body.

11. The humidification and air cleaning apparatus of claim 10 , wherein the installation part comprises:
a diffusion member installation part at which the diffusion member is disposed; and
an electronic component installation part at which the first light emitting member, the second light emitting member, and the printed circuit board are disposed.

12. The humidification and air cleaning apparatus of claim 11 , wherein the diffusion member installation part protrudes to the inside of the visual body, and the diffusion member is disposed at an upper side of the diffusion member installation part.

13. The humidification and air cleaning apparatus of claim 11 , wherein the electronic component installation part protrudes to the inside of the visual body, and the printed circuit board, the first light emitting member, and the second light emitting member are disposed at an upper side of the electronic component installation part.

14. The humidification and air cleaning apparatus of claim 11 , further comprising a drainage part disposed on at least one of the diffusion member installation part or the electronic component installation part to drain water.
