Abstract

An air washer includes an outer case having an air suction port, a water tub disposed in the outer case to store water, a humidification unit disposed in the water tub, a display unit disposed so as to be spaced apart from the outer case to form an air discharge port, the display unit having a water supply port, through which water is supplied, an inner case located at an upper side of the water tub, the inner case having an air channel, connecting the air suction port with the air discharge port, and a water channel, along which the water injected through the water supply port is guided to the water tub, and a blower disposed in the inner case to blow air suctioned through the air suction port to the air discharge port.

First claim

What is claimed is:

1. An air washer comprising:
an outer case having an air intake port;
a water tub provided in the outer case to store water;
a humidification module disposed in the water tub;
a display module disposed so as to be spaced apart from the outer case to form an air discharge port, the display module forming a water supply port to allow water to be supplied;
an inner case located at an upper side of the water tub, the inner case having an air channel, connecting the air intake port with the air discharge port, and a water channel, along which the water injected through the water supply port is guided to the water tub; and
a blower provided in the inner case to blow air suctioned through the air intake port to the air discharge port, wherein the display module includes:
a top cover, in which the water supply port is formed, the top cover being exposed to an outside; and
a lower cover coupled to a lower side of the top cover, the air discharge port being defined by the lower cover, wherein the top cover and the lower cover are coupled to each other to define a receiving space therein, and the display module further includes an inner installation plate, on which a display is installed, disposed in the receiving space, and wherein the inner installation plate is provided in a center thereof with a hollow part, and an inside of the top cover, in which the water supply port is formed, extends downward through the hollow part.

2. The air washer according to claim 1 , wherein the air channel is formed inside the inner case, and the water channel is formed outside the inner case.

3. The air washer according to claim 1 , wherein the water supply port is formed through the display module in a vertical direction, and the air discharge port is disposed outside the display unit.

4. The air washer according to claim 1 , wherein the air discharge port is formed to have a circular shape.

5. The air washer according to claim 1 , wherein the display module is provided around the water supply port.

6. The air washer according to claim 1 , wherein the water channel includes an upper water supply guide located at an upper side of the inner case to guide the water supplied through the water supply port, and a lower water supply guide configured to guide the water guided by the upper water supply guide to the water tub.

7. The air washer according to claim 6 , wherein the upper water supply guide includes a central pan configured to store water falling from the water supply port, and at least one water guide configured to guide the water stored in the central pan to the lower water supply guide, the at least one water guide having a water channel connected to the central pan.

8. The air washer according to claim 7 , further comprising a contoured decoration panel disposed in the center part at a lower side of the water supply port to guide the water falling from the water supply port to the at least one water guide.

9. The air washer according to claim 7 , wherein the at least one water guide is disposed in the air channel of the inner case, and air guided through the inner case flows around the at least one water guide and then flows to the air discharge port.

10. The air washer according to claim 7 , wherein the at least one water guide is disposed in a bridge form connecting the central pan to the lower water supply guide.

11. The air washer according to claim 7 , wherein the at least one water guide comprises a plurality of protrusions radially extending from the central pan.

12. The air washer according to claim 6 , wherein the lower water supply guide is provided at an end thereof with an outlet, which is located inside the water tub.

13. The air washer according to claim 6 , further comprising:
the upper water supply guide being disposed at a lower side of the discharge grill.

14. The air washer according to claim 1 , wherein the humidification module comprises:
a disk assembly comprising a plurality of disks disposed such that the disks are partially immersed in the water tub; and
a disk rotating mechanism configured to rotate the disk assembly,
an upper part of the disk assembly being disposed such that a portion of the upper part of the disk assembly is inserted in the inner case.

15. An air washer comprising:
an outer case having an air intake port;
a water tub provided in the outer case to store water;
a humidification module disposed in the water tub;
a display module disposed so as to be spaced apart from the outer case to form an air discharge port, the display module forming a water supply port to allow water to be supplied;
an inner case located at an upper side of the water tub, the inner case having an air channel, connecting the air intake port with the air discharge port, and a water channel, along which the water injected through the water supply port is guided to the water tub; and
a blower provided in the inner case to blow air suctioned through the air intake port to the air discharge port, wherein the water channel includes an upper water supply guide located at an upper side of the inner case to guide the water supplied through the water supply port, and a lower water supply guide configured to guide the water guided by the upper water supply guide to the water tub, and wherein the upper water supply guide includes a central pan configured to store water falling from the water supply port, and at least one water guide configured to guide the water stored in the central pan to the lower water supply guide, the at least one water guide having a water channel connected to the central pan.

16. The air washer according to claim 15 , further comprising a contoured decoration panel disposed in the center part at a lower side of the water supply port to guide the water falling from the water supply port to the at least one water guide.

17. The air washer according to claim 15 , wherein the at least one water guide is disposed in the air channel of the inner case, and air guided through the inner case flows around the at least one water guide and then flows to the air discharge port.

18. The air washer according to claim 15 , wherein the at least one water guide is disposed in a bridge form connecting the central pan to the lower water supply guide, wherein the at least one water guide comprises a plurality of protrusions radially extending from the central pan, and wherein the at least one water guide is configured in a duct form.
