Abstract

Provided is a humidification and air cleaning apparatus. The humidification and cleaning apparatus includes: a water tank storing water; an air wash inlet disposed in the water tank and communicating the inside of the water tank with the outside thereof; a water tank humidification medium covering the air wash inlet, formed of a material absorbing water, and humidifying air passing the air wash inlet; a watering housing disposed inside the water tank, suctioning water of the water tank thereinto, pumping the suctioned water to an upper side when rotating, and spraying the pumped water; and a watering motor providing a torque to the watering housing. Here, the water tank humidification medium is spaced from water stored in the water tank and is wetted by water sprayed from the watering unit.

First claim

What is claimed is:

1. An apparatus comprising:
a water tank to store water, the water tank having a bottom wall and a side wall extending upward from the bottom wall;
an air wash inlet formed at the side wall of the water tank to receive external air into the water tank;
a water tank humidification medium covering at least a portion of the air wash inlet, the water tank humidification medium being formed of a water absorbent material to humidify air passing through the air wash inlet; and
a watering housing disposed in the water tank, the watering housing having a bottom surface that is open to draw the water of the water tank therein and a nozzle to spray the drawn water toward the outside in a radial direction,
wherein the water tank humidification medium is spaced apart from a portion of the water tank where the water is stored and is wetted by the sprayed water,
wherein the water tank humidification medium is formed in a shape of a hopper having a gradually larger horizontal sectional area at an upper side than at a lower side.

2. The apparatus of claim 1 , wherein air passing through the air wash inlet is pressurized so as to flow from the outside to the inside of the water tank.

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

4. The apparatus of claim 1 , wherein the water tank humidification medium comprises a lower end that is disposed inside the water tank.

5. The apparatus of claim 1 , wherein the water tank humidification medium comprises an upper end that is disposed outside the water tank and a lower end that is disposed inside the water tank.

6. The apparatus of claim 1 , wherein the water tank humidification medium comprises a lower end that is overlapped with a portion of the water tank.

7. The apparatus of claim 1 , further comprising:
a water tank humidification medium housing to house the water tank humidification medium,
wherein the water tank humidification medium housing is separably attached to the water tank.

8. The apparatus of claim 7 , wherein the water tank humidification medium housing comprises a lower end that is disposed inside the water tank.

9. The apparatus of claim 7 , wherein the water tank humidification medium housing comprises an upper end that is disposed outside the water tank and a lower end that is disposed inside the water tank.

10. The apparatus of claim 7 , wherein the water tank humidification medium housing comprises a lower end that is overlapped with the water tank.

11. The apparatus of claim 1 , further comprising a visual body that is formed of a transparent material, wherein the visual body forms at least a portion of the water tank.

12. The apparatus of claim 11 , wherein the nozzle sprays the stored water to an inner side surface of the visual body,
wherein the air wash inlet is disposed below the visual body,
wherein the water tank humidification medium is wetted by water flowing down along an inner surface of the visual body, and
wherein air passing through the air wash inlet is humidified through the wetted water tank humidification medium.

13. The apparatus of claim 11 , wherein the water tank humidification medium housing is separably attached to the visual body.

14. The apparatus of claim 12 , wherein the visual body comprises a reservoir to store the water that has flowed down along the inner surface of the visual body, at least part of the water tank humidification medium housing being disposed on the reservoir.

15. The apparatus of claim 14 , wherein the water tank humidification medium housing comprises a guide, the guide being disposed over the reservoir and inclined in a direction toward the inside of the water tank.

16. The apparatus of claim 7 , wherein the water tank humidification medium housing comprises:
an inner medium frame having an inner medium inlet formed therein for air to pass therethrough, and
an outer medium frame having an outer medium inlet formed therein for air to pass therethrough,
whereby the water tank humidification medium is disposed between the inner frame and the outer frame so that air passing through the water tank humidification medium sequentially passes the air wash inlet, the outer medium inlet, and the inner medium inlet.

17. The apparatus of claim 1 , wherein when the water tank is full of water, a lower end of the water tank humidification medium is located above the water surface.
