Abstract

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes: a water tank storing water; and a discharge humidification medium housing disposed over the water tank and disposed over a discharge flow passage flowing via the water tank and the water supply flow passage supplying water into the water tank. Here, the discharge humidification medium housing includes: a reservoir disposed in the water supply flow passage and storing water supplied into the water tank when water is supplied from the upper side; and a water outlet formed in the reservoir and supplying water of the reservoir into the water tank.

First claim

What is claimed is:

1. A humidification and air cleaning apparatus comprising:
a water tank to store water; and
a discharge humidification medium housing disposed on the water tank,
wherein the discharge humidification medium housing comprises:
a discharge flow passage to discharge air,
a water supply flow passage to supply water into the water tank, and
a reservoir disposed in the water supply flow passage to store water and to supply stored water into the water tank.

2. The humidification and air cleaning apparatus of claim 1 , wherein a water outlet is formed in the reservoir to discharge water into the water tank.

3. The humidification and air cleaning apparatus of claim 1 , further comprising a discharge humidification medium disposed inside the discharge humidification medium housing, covering the discharge flow passage, and providing humidification to air passing through the discharge flow passage.

4. The humidification and air cleaning apparatus of claim 3 , wherein when the water supplied to the reservoir exceeds the capacity of the reservoir, the excess water overflows to the discharge flow passage and wets the discharge humidification medium.

5. The humidification and air cleaning apparatus of claim 4 , wherein water remaining after wetting the discharge humidification medium flows to the water tank through the discharge flow passage.

6. The humidification and air cleaning apparatus of claim 1 , further comprising a top cover assembly disposed above the discharge humidification medium housing,
wherein the top cover assembly comprises an operation water inlet communicating with the water supply flow passage and a grille discharge port communicating with the discharge flow passage, and
wherein water supplied through the water supply flow passage is guided to the reservoir through the operation water inlet.

7. The humidification and air cleaning apparatus of claim 1 , wherein the reservoir is disposed inside the discharge humidification medium housing, and the discharge flow passage is located outside the reservoir.

8. The humidification and air cleaning apparatus of claim 1 , further comprising a discharge humidification medium disposed inside the discharge humidification medium housing, covering the discharge flow passage, and providing humidification to air passing through the discharge flow passage,
wherein the discharge humidification medium housing comprises:
a housing disposed over and under the discharge humidification medium,
a housing opening vertically disposed inside the housing, the housing opening forming the water supply flow passage, and
a water supply cap covering the housing opening,
whereby the reservoir is disposed between the water supply cap and the housing.

9. The humidification and air cleaning apparatus of claim 8 , wherein the water supply cap is formed of a transparent material.

10. The humidification and air cleaning apparatus of claim 8 , wherein water supplied from the upper side is guided to the reservoir along a surface of the water supply cap.

11. The humidification and air cleaning apparatus of claim 8 , wherein when the water supplied to the reservoir exceeds the capacity of the reservoir, the excess water overflows to a portion of the housing to wet the discharge humidification medium.

12. The humidification and air cleaning apparatus of claim 8 , further comprising a body forming at least a portion of the water tank, the body being formed of a transparent material,
wherein water remaining after wetting the discharge humidification medium drops on the body and then flows to the water tank.

13. The humidification and air cleaning apparatus of claim 8 , wherein a water outlet is formed inside the water supply cap to discharge water stored in the reservoir.

14. The humidification and air cleaning apparatus of claim 8 , further comprising a watering housing disposed inside the water tank,
wherein water stored in the reservoir drops on an upper part of the watering housing.

15. The humidification and air cleaning apparatus of claim 1 , further comprising a discharge humidification medium disposed inside the discharge humidification medium housing, the discharge humidification medium covering the discharge flow passage and providing humidification to air passing through the discharge flow passage,
wherein the discharge humidification medium housing comprises:
an upper housing disposed above the discharge humidification medium and supporting the discharge humidification medium;
an upper housing opening formed in the upper housing and forming the water supply flow passage;
a lower housing disposed below the discharge humidification medium and supporting the discharge humidification medium; and
a lower housing opening formed in the lower housing and forming the water supply flow passage, the lower housing opening being disposed below the upper housing opening,
whereby the reservoir is formed in at least one of the upper housing and the lower housing.

16. The humidification and air cleaning apparatus of claim 15 , wherein a water outlet is formed in at least one of the upper housing and the lower housing to discharge water stored in the reservoir.

17. The humidification and air cleaning apparatus of claim 15 , further comprising a water supply cap disposed above the upper housing opening or the lower housing opening and coupled to at least one of the upper housing and the lower housing,
wherein the water supply cap is disposed to guide water supplied from the water supply flow passage to the reservoir.

18. The humidification and air cleaning apparatus of claim 15 , further comprising:
a reservoir base formed in at least one of the upper housing and the lower housing;
a reservoir wall upwardly extending from the reservoir base to form the reservoir; and
a water supply cap disposed above the upper housing opening or the lower housing opening and coupled to at least one of the upper housing and the lower housing,
wherein the reservoir is formed above the reservoir base, inside the reservoir wall, and outside the water supply cap.

19. The humidification and air cleaning apparatus of claim 18 , wherein a water outlet is formed in the reservoir base to discharge water stored in the reservoir.
