Abstract

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes: a water tank storing water; a watering housing disposed inside the water tank, suctioning water of the water tank thereinto, pumping the suctioned water to an upper side when rotating, and spraying the pumped water; a watering motor providing a torque to the watering housing; and a power transmission shaft disposed inside the watering housing, connecting the watering motor and the watering housing, and delivering a torque of the watering motor to the watering housing.

First claim

What is claimed is:

1. A humidification and air cleaning apparatus comprising:
a water tank to store water, the water tank having a bottom wall and a side wall extending upward from the bottom wall;
a watering housing disposed inside the water tank;
a watering motor to generate a torque; and
a power transmission shaft disposed inside the watering housing to deliver a torque of the watering motor to the watering housing,
wherein the watering housing comprises a bottom surface that is opened and a lower end that is spaced from the bottom wall of the water tank by a suction gap, and
wherein the power transmission shaft penetrates the bottom wall of the water tank.

2. The humidification and air cleaning apparatus of claim 1 , wherein the watering housing further comprises a watering connection part disposed inside therein and protruding inward, wherein the power transmission shaft is coupled to the watering connection part to deliver a torque.

3. The humidification and air cleaning apparatus of claim 1 , further comprising a bushing installed at the power transmission shaft, wherein the bushing is formed of a metallic material.

4. The humidification and air cleaning apparatus of claim 3 , wherein the bushing is located higher than a full water level of the water tank.

5. The humidification and air cleaning apparatus of claim 1 , wherein:
the water tank further comprises a column disposed inside the watering housing,
the column upwardly protrudes inside the watering housing, and
the power transmission shaft penetrates the column to be coupled to the watering housing.

6. The humidification and air cleaning apparatus of claim 5 , further comprising a power transmission housing disposed inside the column,
wherein:
the power transmission housing is supported inside the column,
the power transmission housing has a hollow that the power transmission shaft penetrates, and
the power transmission shaft penetrates the power transmission housing and the column to be coupled to the watering housing.

7. The humidification and air cleaning apparatus of claim 6 , further comprising a bearing disposed inside the power transmission housing, wherein the power transmission shaft penetrates the bearing.

8. The humidification and air cleaning apparatus of claim 6 , further comprising a shaft gasket disposed inside the power transmission housing, wherein the shaft gasket seals the hollow, and the power transmission shaft penetrates the shaft gasket.

9. The humidification and air cleaning apparatus of claim 6 , wherein the power transmission housing is fixed to the water tank.

10. The humidification and air cleaning apparatus of claim 1 , wherein the watering housing comprises:
a first watering housing spaced apart from an undersurface of an inner side of the water tank by a suction gap and having upper and a lower sides thereof opened, respectively;
a second watering housing having upper and lower sides opened, assembled with an upper end of the first watering housing;
a watering housing cover coupled with an upper end of the second watering housing to cover an upper of the second watering housing; and
a power transmission unit disposed in at least one of the first watering housing, the second watering housing and the watering housing cover to receive a torque from the watering motor,
wherein the power transmission shaft is coupled to the power transmission unit.

11. The humidification and air cleaning apparatus of claim 10 , wherein the power transmission shaft has an upper end thereof coupled to the watering housing cover.

12. The humidification and air cleaning apparatus of claim 10 , further comprising a bushing installed at the power transmission unit,
wherein the power transmission shaft penetrates the bushing to be coupled, and the power transmission shaft has an upper end thereof coupled to the watering housing cover.

13. The humidification and air cleaning apparatus of claim 10 , further comprising a column upwardly protruding from a bottom of the water tank,
wherein the power transmission shaft penetrates the column to be coupled to the watering housing, and the column is disposed under the power transmission unit.

14. The humidification and air cleaning apparatus of claim 13 , further comprising a power transmission housing disposed inside the column,
wherein the power transmission housing comprises:
a bearing housing having upper and lower sides thereof opened;
a housing cap coupled to an upper side of the bearing housing, wherein the power transmission shaft penetrates through the housing cap in a vertical direction;
a shaft gasket disposed between the housing cap and the power transmission shaft and fixed to the housing cap; and
a housing elastic member disposed between the bearing housing and the housing cap to provide an elastic force.
