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 top cover assembly disposed over the water tank and including a water supply flow passage disposed therein to supply water into the water tank; a watering housing disposed inside the water tank and rotating inside the water tank; and a watering motor rotating the watering housing. Here, when the watering housing rotates, water supplied to the water supply flow passage drops on the watering housing to be scattered.

First claim

What is claimed is:

1. A humidification and air cleaning apparatus comprising:
a water tank to store water;
a body forming at least a portion of the water tank, the body being formed of a transparent material;
a top cover assembly disposed above the water tank, the top cover assembly having a water supply flow passage disposed therein to supply water into the water tank; and
a watering housing disposed inside the water tank, the watering housing being rotatable,
wherein during rotation of the watering housing, the water supplied to the water supply flow passage is scattered by the watering housing.

2. The apparatus of claim 1 , wherein the water scattered by the watering housing forms droplets on an inner side surface of the body.

3. The apparatus of claim 1 , wherein the watering housing further comprises a protrusion that protrudes from an outer surface of the watering housing.

4. The apparatus of claim 1 , further comprising a watering blade disposed inside the watering housing, whereby during rotation of the watering housing, water located within a radius of rotation of the watering blade collides with the watering blade and is scattered.

5. The apparatus of claim 1 , wherein the watering housing comprises:
a watering blade disposed inside the watering housing; and
a nozzle to spray the water stored in the water tank,
wherein during rotation of the watering housing, water sprayed from the nozzle collides with the watering blade and is scattered.

6. The apparatus of claim 1 , further comprising a motor to rotate the watering housing,
wherein the watering housing comprises:
a first watering housing spaced from a bottom surface of an inner side of the water tank by a suction gap;
a second watering housing coupled with an upper end of the first watering housing;
a watering housing cover coupled with an upper end of the second watering housing;
a power transmission unit disposed in at least one of the first watering housing and the second watering housing to receive a torque from the motor; and
a nozzle disposed in at least one of the first watering housing and the second watering housing to spray water from inside the watering housing to a water tank humidification medium during rotation of the watering housing.

7. The apparatus of claim 6 , further comprising a watering blade disposed inside the watering housing,
whereby during rotation of the watering housing, water dropping from the water supply flow passage collides with the watering blade and is scattered.

8. The apparatus of claim 6 , further comprising a watering blade disposed inside the watering housing,
whereby during rotation of the watering housing, water sprayed from the nozzle collides with the watering blade and is scattered.

9. The apparatus of claim 6 , wherein the watering housing cover further comprises a protrusion that protrudes outward.

10. The apparatus of claim 9 , wherein the protrusion includes more than one protrusion disposed along a circumference of the watering housing cover.

11. The apparatus of claim 1 , wherein the watering housing further comprises a nozzle to spray water,
whereby during rotation of the watering housing, the water stored in the water tank is drawn to the inside of the watering housing and the drawn water is sprayed through the nozzle.

12. The apparatus of claim 11 , wherein the nozzle includes more than one nozzle, the nozzles being disposed on the watering housing at different heights.

13. The apparatus of claim 12 , wherein the nozzles comprise a first nozzle and a second nozzle, the first nozzle being disposed at a middle portion of the watering housing and the second nozzle being disposed above the first nozzle, whereby water sprayed from the first nozzle is used to humidify air passing through the water tank and water sprayed from the second nozzle contacts the inner side surface of the body.

14. The apparatus of claim 13 , further comprising a water tank humidification medium formed of a water absorbent material,
wherein the water sprayed from the second nozzle flows down from the inner side surface of the body and wets the water tank humidification medium.

15. The apparatus of claim 13 , wherein the water sprayed from the second nozzle contacts the inner side surface of the body and is scattered to form a rain view.

16. The apparatus of claim 13 , wherein the water sprayed from the second nozzle contacts the inner side surface of the body and is changed into water droplets that are used to humidify air passing through the water tank.

17. The apparatus of claim 13 , wherein when the watering housing rotates at or above a first predetermined speed, water is sprayed from the first nozzle, and when the watering housing rotates at or above a second predetermined speed, water is sprayed from the second nozzle, whereby the second rotation speed is greater than the first rotation speed.

18. The apparatus of claim 13 , wherein the watering housing comprises a plurality of at least one of the first and the second nozzles.

19. The apparatus of claim 1 , wherein the lower end of the watering housing is spaced apart from the bottom surface of the water tank by a predetermined gap to form a suction gap, whereby the water stored in the storage tank is drawn into the watering housing through the suction gap.

20. The apparatus of claim 19 , wherein the water is only drawn into the watering housing when the water level of the water stored in the storage tank is above than the height of the suction gap, and the drawn water is only sprayed by the nozzle when the water level is below the height of the nozzle.
