Abstract

A humidification and air cleaning apparatus is provided, in which a shield prevents water, discharged from an upper nozzle, from being scattered upward, thereby preventing droplets from being scattered to a discharge port which is open to as upper side of a water tank.

First claim

What is claimed is:

1. A humidification and air cleaning apparatus, comprising:
a humidification housing having an upper opening and a lower opening;
a first upper nozzle that passes through the humidification housing;
a second upper nozzle that passes through the humidification housing;
a housing cover that closes an upper surface of the humidification housing; and
a shield disposed at an outer edge of the housing cover and spaced apart from an outer surface of the humidification housing, wherein the shield is disposed below either the first upper nozzle or the second upper nozzle.

2. The apparatus of claim 1 , wherein the first upper nozzle is disposed below the second upper nozzle, and the shield is disposed below the second upper nozzle.

3. The apparatus of claim 1 , wherein the first upper nozzle and the second upper nozzle are disposed at a same height, and the shield is disposed below the second upper nozzle.

4. The apparatus of claim 1 , wherein the housing cover comprises a top wall that covers the upper opening of the humidification housing, and a side wall that extends downwardly from the top wall and covers an upper end of the humidification housing, wherein the shield extends downwardly from a lower end of the side wall.

5. The apparatus of claim 4 , wherein the side wall is disposed outside of the second upper nozzle to cover the second upper nozzle, and wherein the side wall and the second upper nozzle are spaced apart from each other by a predetermined distance.

6. The apparatus of claim 4 , wherein the shield is disposed below the second upper nozzle.

7. The apparatus of claim 4 , wherein the shield is disposed at a same height as or above the first upper nozzle and below the second upper nozzle.

8. The apparatus of claim 4 , further comprising an inner rib disposed under the top wall and spaced apart from the side wall by a predetermined distance, wherein the upper end of the humidification housing is disposed between the inner rib and the side wall.

9. The apparatus of claim 8 , wherein the second upper nozzle is disposed between a lower end of the inner rib and an upper end of the shield.

10. The apparatus of claim 4 , wherein the shield comprises:
a shield portion spaced apart from the outer surface of the humidification housing; and
a scatter portion that protrudes outwardly in a radial direction from the shield portion, wherein the shield portion protrudes outwardly in the radial direction from the side wall with respect to a rotational axis of the humidification housing and is inclined downwardly.

11. The apparatus of claim 10 , wherein the scatter portion protrudes outwardly in the radial direction from a lower end of the shield portion.

12. The apparatus of claim 10 , wherein the scatter portion is disposed below the second upper nozzle.

13. The apparatus of claim 10 , wherein the scatter portion is disposed at a same height as or above the first upper nozzle.

14. The apparatus of claim 10 , wherein an outer surface of the shield portion and the scatter portion form an included angle of greater than 90 degrees and less than 180 degrees.

15. The apparatus of claim 10 , wherein an inner surface of the shield portion is open downwardly and toward the rotational axis.

16. The apparatus of claim 10 , wherein the inner surface of the shield portion has a rounded shape which is recessed upwardly from a bottom side.

17. A humidification and air cleaning apparatus, comprising:
a humidification housing having an upper opening and a lower opening;
a first upper nozzle that passes through the humidification housing;
a second upper nozzle that passes through the humidification housing;
a housing cover that closes at least the upper opening of the humidification housing; and
a shield disposed outside of the upper opening of the humidification housing, wherein the shield is disposed below either the first upper nozzle or the second upper nozzle, and wherein the shield is disposed to surround an upper end of humidification housing.

18. The apparatus of claim 17 , wherein the first upper nozzle is disposed below the second upper nozzle, and the shield is disposed below the second upper nozzle.

19. The apparatus of claim 17 , wherein the first upper nozzle and the second upper nozzle are disposed at a same height, and the shield is disposed below the second upper nozzle.

20. The apparatus of claim 17 , wherein the humidification housing cover comprises a top wall that covers the upper opening of the humidification housing, and a side wall that extends downwardly from the top wall and covers an upper end of the humidification housing, wherein the shield extends downwardly from a lower end of the side wall.
