Abstract

A humidification and air cleaning apparatus is provided that may include a water tank having a discharge port which is open toward an upper side, and a discharge grill disposed at the water tank and covering the discharge port. The discharge grill may have a plurality of vanes disposed at the discharge port and spaced apart from each other, and when viewed from a top, overlap each other to cover the discharge port. An edge of a vane may overlap an edge of an adjacent vane, thereby minimizing scattering of droplets to an indoor space while minimizing resistance of discharged air.

First claim

What is claimed is:

1. A humidification and air cleaning apparatus, comprising:

a discharge grill disposed on the water tank and covering the discharge port, wherein the discharge grill includes a plurality of vanes which is disposed in the discharge port and spaced apart from each other, and when viewed from a top, overlaps each other to cover the discharge port, wherein the discharge grill comprises a lower grill disposed inside of the water tank and covering the discharge port, and an upper grill disposed above the lower grill, wherein the upper grill has a plurality of upper vanes forming first discharge areas; the lower grill has a plurality of lower vanes forming second discharge areas; and the plurality of upper vanes is disposed over the second discharge areas, and when viewed from the top, covers the second discharge areas, and wherein at least either the plurality of lower vanes or the plurality of upper vanes is inclined with respect to a vertical direction.

2. The apparatus of claim 1 , wherein the plurality of lower vanes is disposed below the first discharge areas, and when viewed from the top, covers the first discharge areas.

3. The apparatus of claim 1 , wherein a direction of inclination of the plurality of lower vanes intersects a direction of inclination of the plurality of upper vanes.

4. The apparatus of claim 1 , wherein the plurality of upper vanes is disposed radially with respect to a center of the upper grill, and the plurality of lower vanes is disposed radially with respect to a center of the lower grill.

5. The apparatus of claim 4 , wherein the plurality of upper vanes is arranged in a circumferential direction with respect to the center of the upper grill; and the plurality of lower vanes is arranged in a circumferential direction with respect to the center of the lower grill.

6. The apparatus of claim 1 , wherein the upper grill comprises:
an upper inner frame having an upper grill water supply port formed at a center thereof;
an upper outer frame spaced apart from the upper inner frame and surrounding the upper inner frame;
the plurality of upper vanes which connects the upper inner frame and the upper outer frame; and
the second discharge areas which are formed between the plurality of upper vanes.

7. The apparatus of claim 6 , wherein the center of the upper grill is formed inside of the upper inner frame, and wherein the plurality of upper vanes and the second discharge areas are disposed radially with respect to the center of the upper grill.

8. The apparatus of claim 1 , wherein the discharge grill is detachably placed in the water tank.

9. The apparatus of claim 1 , wherein the discharge grill comprises:
an inner frame having a grill water supply port formed thereinside;
an outer frame spaced apart from the inner frame and surrounding the inner frame;
the plurality of vanes which connects the inner frame and the outer frame; and
discharge areas formed between the plurality of vanes.

10. The apparatus of claim 9 , wherein the plurality of vanes is inclined with respect to a vertical direction, and when viewed from the top, an upper end of any one of the plurality of vanes overlaps a lower end of an adjacent vane.

11. The apparatus of claim 1 , wherein the discharge grill comprises:
an inner frame having a grill water supply port formed thereinside;
an outer frame being spaced apart from the inner frame and surrounding the inner frame;
a connection frame that connects the inner frame and the outer frame;
the plurality of vanes disposed between the inner frame and the outer frame and surrounding the inner frame; and
discharge areas formed between the plurality of vanes.

12. The apparatus of claim 11 , wherein when viewed from the top, the plurality of vanes form a concentric circle.

13. A humidification and air cleaning apparatus, comprising:
a water tank having a discharge port which is open toward an upper side; and
a discharge grill disposed on the water tank and covering the discharge port, wherein the discharge grill includes a plurality of vanes which is disposed in the discharge port and spaced apart from each other, and when viewed from a top, overlaps each other to cover the discharge port, wherein the discharge grill comprises a lower grill disposed inside of the water tank and covering the discharge port, and an upper grill disposed above the lower grill, wherein the upper grill has a plurality of upper vanes forming first discharge areas; the lower grill has a plurality of lower vanes forming second discharge areas; and the plurality of upper vanes is disposed over the second discharge areas, and when viewed from the top, covers the second discharge areas, wherein the upper grill comprises:
an upper inner frame having an upper grill water supply port formed at a center thereof;
an upper outer frame spaced apart from the upper inner frame and surrounding the upper inner frame;
the plurality of upper vanes which connects the upper inner frame and the upper outer frame; and
the second discharge areas which are formed between the plurality of upper vanes, and wherein the lower grill comprises:
a lower inner frame having a lower grill water supply port formed at a center thereof;
a lower outer frame spaced apart from the lower inner frame and surrounding the lower inner frame;
the plurality of lower vanes which connects the lower inner frame and the lower outer frame; and
the first discharge areas formed between the plurality of lower vanes.

14. The apparatus of claim 13 , wherein a center of the lower grill is formed inside of the lower inner frame, and wherein the plurality of lower vanes and the first discharge areas are disposed radially with respect to the center of the lower grill.

15. The apparatus of claim 13 , wherein the plurality of upper vanes is disposed over the second discharge areas, and the plurality of lower vanes is disposed below the first discharge areas, and wherein when viewed from the top, the plurality of upper vanes covers the second discharge areas.

16. A humidification and air cleaning apparatus, comprising:
a water tank having a discharge port which is open toward an upper side; and
a discharge grill disposed on the water tank and covering the discharge port, wherein the discharge grill includes a plurality of vanes which is disposed in the discharge port and spaced apart from each other, and when viewed from a top, overlaps each other to cover the discharge port, wherein the discharge grill is detachably placed in the water tank; and
a top cover configured to receive an operation signal from a user, wherein the top cover is detachably placed over the discharge grill and is spaced apart from the plurality of upper vanes.
