Abstract

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes: a water tank storing water; a visual body forming at least a portion of the water tank and formed of a transparent material; a watering housing disposed in the water tank, suctioning water stored in the water tank to pump water to an upper side, and spraying the pumped water; a watering motor rotating the watering housing; and a watering blade formed to outwardly protrude from the watering housing. Here, when the watering housing rotates, the watering blade collides with water droplets within a radius of rotation of the watering blade to scatter water droplets.

First claim

What is claimed is:

1. A humidification and air cleaning apparatus comprising:
a water tank configured to store water, the water tank comprising a bottom wall and a side wall extending upward from the bottom wall;
a watering housing that is rotatable and disposed in the water tank to spray water stored in the water tank, the watering housing comprising a bottom surface that is opened, a lower end that is spaced apart from the bottom surface by a suction gap, and a nozzle, the watering housing configured such that during rotation, the stored water is suctioned from the water tank to an inside of the watering housing and upwardly pumped, and the pumped water is sprayed through the nozzle;
a watering housing cover closing an upper side of the watering housing and forming an upper surface of the watering housing;
a watering motor rotating the watering housing; and
a watering blade formed to outwardly protrude from an outer surface of the watering housing,
wherein the nozzle is disposed on a side wall of the watering housing,
wherein the watering blade is disposed in the side wall of the watering housing and extends in a vertical direction.

2. The humidification and air cleaning apparatus of claim 1 , wherein
the watering blade is disposed to collide with water sprayed from the nozzle.

3. The humidification and air cleaning apparatus of claim 2 , wherein a portion of a trajectory of water sprayed from the nozzle is located inside a radius of rotation of the watering blade.

4. The humidification and air cleaning apparatus of claim 2 , wherein the watering blade is disposed in plurality, and the nozzle is disposed between the watering blades.

5. The humidification and air cleaning apparatus of claim 2 , wherein the nozzle is located above the watering blade.

6. The humidification and air cleaning apparatus of claim 2 , wherein the nozzle is disposed in plurality, and each nozzle is disposed to spray water in different directions.

7. The humidification and air cleaning apparatus of claim 1 , further comprising a visual body forming at least a portion of the water tank and formed of a transparent material,
wherein the nozzle is disposed to spray water toward the water tank.

8. The humidification and air cleaning apparatus of claim 1 , wherein the watering housing cover comprises a water supply flow passage disposed therein to supply water into the water tank,
wherein when the watering housing rotates, a portion of water dropping onto the water tank through the water supply flow passage collides with the watering blade to be scattered.

9. The humidification and air cleaning apparatus of claim 8 , wherein water supplied through the water supply flow passage drops on the watering housing.

10. The humidification and air cleaning apparatus of claim 9 , wherein when the watering housing rotates, water dropping on the watering housing is scattered to an inner side surface of the water tank.

11. The humidification and air cleaning apparatus of claim 1 , wherein the watering housing comprises:
a first watering housing spaced from a undersurface of an inner side of the water tank by a suction gap and having upper and a lower sides thereof opened, respectively;
a second watering housing having upper and lower sides opened, assembled with an upper end of the first watering housing, and communicating with the inside of the first watering housing;
the watering housing cover coupled with an upper end of the second watering housing and covering an upper surface of the second watering housing;
a power transmission unit disposed in at least one of the first watering housing, the second watering housing and the watering housing cover and receiving a torque from the watering motor; and
the nozzle disposed in at least one of the first watering housing and the second watering housing and spraying pumped water,
wherein the watering blade is disposed in the second watering housing.

12. The humidification and air cleaning apparatus of claim 11 , wherein when the watering housing rotates, the watering blade is disposed to collide with water sprayed from the nozzle.

13. The humidification and air cleaning apparatus of claim 11 , wherein the nozzle is disposed between the watering blade and the watering housing cover.

14. The humidification and air cleaning apparatus of claim 11 , wherein the nozzle is disposed to spray water toward the water tank.

15. The humidification and air cleaning apparatus of claim 11 , wherein the watering housing cover overlaps a portion of the nozzle, and generates an interference with water sprayed from the nozzle.

16. The humidification and air cleaning apparatus of claim 11 , wherein a portion of a trajectory of water sprayed from the nozzle is located inside a radius of rotation of the watering blade.

17. The humidification and air cleaning apparatus of claim 11 , wherein the nozzle is disposed in plurality, and each nozzle is disposed to spray water in different directions, and
the watering housing cover overlaps at least one of the nozzles, and generates an interference with water sprayed from the overlapped nozzle.

18. The humidification and air cleaning apparatus of claim 11 , wherein the watering housing cover has an outside diameter larger than an outside diameter of the second watering housing.

19. The humidification and air cleaning apparatus of claim 8 , wherein a trajectory of water scattering from the watering housing cover is located above a trajectory of water sprayed from the nozzle.
