Abstract

A humidifier may be provided that includes a main body having a discharge part, a base on which the main body is seated, a tray seated on the base to store water, a disk assembly seated on the tray to humidify air, a filter assembly disposed in the main body to filter the humidified air, and a fan disposed at a downstream side of the filter assembly.

First claim

What is claimed is:

1. A humidifier comprising:
a base;
a main body having a discharge part, the main body being on the base;
a tray, on the base, to store water;
a disk assembly, on the tray, to humidify air;
a filter assembly, in the main body, to filter the humidified air; and
a fan at a downstream side of the filter assembly,
wherein the main body includes a case assembly to surround portions of the fan, and
the filter assembly is separably coupled to the case assembly.

2. The humidifier according to claim 1 , wherein the filter assembly is exposed to an outside of the humidifier when the main body is separated from the base.

3. The humidifier according to claim 1 , wherein the filter assembly covers a lower side of the fan when the filter assembly is on the case assembly, and
the fan is exposed to outside of the humidifier when the filter assembly is separated from the case assembly.

4. The humidifier according to claim 3 , wherein the filter assembly is between the fan and the disk assembly.

5. The humidifier according to claim 1 , further comprising a fan motor to rotate the fan,
wherein a shaft of the fan motor overlaps the filter assembly in a flow direction of the air.

6. The humidifier according to claim 5 , further comprising a motor support to support the fan motor, and
the fan is coupled to the shaft of the fan motor at a lower side of the motor support, when the shaft of the fan motor passes through the motor support.

7. The humidifier according to claim 6 , wherein the motor support includes one or more holes through which the humidified air passes.

8. The humidifier according to claim 1 , wherein at least a portion of the fan overlaps the filter assembly in a flow direction of the air.

9. The humidifier according to claim 1 , wherein the case assembly includes:
an upper case to accommodate the fan; and
a middle case, under the upper case, to cover a portion of the disk assembly, and
the filter assembly is coupled to the middle case.

10. The humidifier according to claim 1 , wherein the filter assembly comprises:
a filter frame to receive a filter; and
a filter case coupled to the filter frame, and
the filter case is coupled to the case assembly.

11. The humidifier according to claim 1 , further comprising a disk motor assembly for operating the disk assembly, and the disk motor assembly is disposed on the case assembly.

12. The humidifier according to claim 1 , wherein the main body includes:
a housing having a suction part through which the air is suctioned, and
a suction filter to filter the air suctioned through the suction part, the suction filter being provided inside the housing.

13. The humidifier according to claim 12 , further comprising an air guide, in the housing, to guide the air filtered by the suction filter toward the disk assembly.

14. A humidifier comprising:
a base;
a tray on the base;
a disk assembly to support the tray;
a main body to cover the disk assembly, the main body having a suction part and a discharge part to discharge the humidified air;
a filter assembly in the main body, the humidified air to pass through the filter assembly; and
a fan motor assembly to provide the humidified air that passes through the filter assembly to the discharge part of the main body,
wherein the main body includes a case assembly to surround a portion of the fan motor assembly, and
the filter assembly is separably coupled to the case assembly.

15. The humidifier according to claim 14 , wherein the filter assembly is disposed above the disk assembly, and the filter assembly is disposed below the fan motor assembly.

16. The humidifier according to claim 14 , wherein the filter assembly includes:
a filter frame to receive a filter; and
a filter case to couple to the filter frame, and
the filter case is coupled to the case assembly.

17. The humidifier according to claim 14 , wherein the main body further includes a suction filter to filter air suctioned through the suction part.

18. The humidifier according to claim 17 , wherein the main body further includes an air guide to guide the air filtered by the suction filter toward the disk assembly.
