Abstract

Provided is a humidification and air cleaning apparatus including a water tank storing water; an air wash inlet formed at the water tank and communicating the inside and the outside of the water tank and a water tank humidification medium formed of a material for absorbing water and providing humidification on air passing through the air wash inlet. The water tank humidification medium is located inside the air wash inlet to cover the air wash inlet.

First claim

What is claimed is:

1. A humidification and air cleaning apparatus comprising:
a water tank to store water, the water tank comprising a bottom wall and a side wall extending upward from the bottom wall;
an air wash inlet formed at the side wall to communicate with the inside and outside of the water tank;
a water tank humidification medium housing located inside the wall or in the air wash inlet, the water tank humidification housing being detachably mounted to the water tank; and
a water tank humidification medium formed of a water absorbent material to humidify air passing through the air wash inlet, the water tank humidification medium being disposed in the water tank humidification medium housing,
wherein the water tank humidification medium covers the air wash inlet,
wherein the water tank humidification medium includes a lower end and an upper end, the lower end being spaced apart from a water surface of the water tank.

2. The humidification and air cleaning apparatus of claim 1 , wherein the air passing through the air wash inlet forms a pressure to flow from the outside of the water tank to the inside of the water tank.

3. The humidification and air cleaning apparatus of claim 1 , wherein the air wash inlet is formed along a circumference of the water tank and the water humidification medium covers the entire air wash inlet.

4. The humidification and air cleaning apparatus of claim 1 , further comprising a watering unit disposed inside the water tank to spray the water stored in the water tank,
wherein water sprayed from the watering unit wets the water tank humidification medium.

5. The humidification and air cleaning apparatus of claim 4 , wherein the lower end of the water tank humidification medium is overlapped with the water tank, and the watering unit sprays water to the overlapped portion.

6. The humidification and air cleaning apparatus of claim 1 , wherein the water tank humidification medium housing comprises a dripping water prevention flow passage to guide water into the water tank.

7. The humidification and air cleaning apparatus of claim 6 , wherein the water tank humidification housing includes an upper end and a lower end, the upper end of the water tank humidification housing being located above an upper end of the air wash inlet, and the lower end of the water tank humidification housing being located below a lower end of the air wash inlet.

8. The humidification and air cleaning apparatus of claim 6 , wherein a lower end of the water tank humidification medium housing is overlapped with the water tank.

9. The humidification and air cleaning apparatus of claim 6 , wherein the water tank humidification medium housing further comprises a guide to guide flowing-down water to the inside of the water tank, the guide being disposed at an upper end of the water tank humidification medium housing.

10. The humidification and air cleaning apparatus of claim 1 , further comprising a visual body made of a transparent material and forming at least a portion of the water tank, wherein the air wash inlet is disposed at a lower side portion of the visual body.

11. The humidification and air cleaning apparatus of claim 10 , wherein a side surface of the visual body is inclined toward the inside of the water tank.

12. The humidification and air cleaning apparatus of claim 10 , wherein a reservoir to store flowing-down water is formed at the inside of the visual body and the reservoir is located at an upper side portion of the air wash inlet.

13. The humidification and air cleaning apparatus of claim 12 , wherein an upper end of the water tank humidification medium housing is overlapped with the visual body and a lower end of the water tank humidification housing is overlapped with the water tank.

14. The humidification and air cleaning apparatus of claim 13 , wherein the water tank humidification medium housing is detachable from the visual body.

15. The humidification and air cleaning apparatus of claim 10 , further comprising a guide disposed at an upper end of the water tank humidification medium housing to guide flowing-down water to the inside of the water tank.

16. The humidification and air cleaning apparatus of claim 10 , further comprising:
a reservoir formed inside the visual body to store lowing-down water; and
a guide disposed at an upper end of the water tank humidification medium housing to guide the flowing-down water to the inside of the water tank,
wherein the guide is located at an upper side of the reservoir.

17. The humidification and air cleaning apparatus of claim 10 , further comprising a top cover assembly disposed at an upper inside of the visual body and forming a water supply flow passage and a discharge flow passage, wherein water flowing to the discharge flow passage flows down along the inside of the visual body and a reservoir to store the flowing-down water is formed at the visual body.

18. The humidification and air cleaning apparatus of claim 1 , further comprising:
a watering unit disposed inside the water tank to spray water stored in the water tank;
wherein
the water sprayed from the watering unit wets the water tank humidification medium, and
the water tank humidification medium housing further comprises a frame disposed outside the air wash inlet and overlapped with the water tank, whereby the watering unit sprays water to the frame.
