Abstract

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a water tank storing water; a visual body forming at least a portion of the water tank and formed of a transparent material; a watering housing disposed in the water tank, drawing water stored in the water tank to pump water to an upper side, and spraying the pumped water; a nozzle disposed in the watering housing and spraying the pumped water; and a watering motor rotating the watering housing. Here, when the watering housing rotates, water sprayed from the nozzle forms at least one spray line on an inner side surface of the visual body.

First claim

What is claimed is:

1. A humidification and air cleaning apparatus comprising:
a water tank comprising a water tank body to store water and a visual body formed of a transparent material, wherein the water tank body comprises a bottom wall and side wall extending upward from the bottom wall;
a watering housing disposed in the water tank, the watering housing comprising a bottom surface that is open and at least one spray nozzle to spray the water stored in the water tank body, wherein a lower end of the watering housing is spaced from the bottom wall of the water tank body by a suction gap; and
a watering motor to rotate the watering housing, wherein the watering motor is connected to the watering housing and disposed below the bottom wall of the water tank body,
wherein the at least one spray nozzle sprays water to form at least one spray line on an inner side surface of the visual body, wherein the at least one spray line is formed in a rotation direction of the watering housing,
wherein at least a portion of the visual body comprises an inclination surface that is inclined, and the at least one spray line is formed on the inclination surface of the visual body.

2. The humidification and air cleaning apparatus of claim 1 , wherein the at least one spray nozzle comprises at least two spray nozzles that respectively form at least two spray lines at different heights.

3. The humidification and air cleaning apparatus of claim 1 , wherein the at least one spray nozzle comprises at least two spray nozzles that are respectively disposed at different heights.

4. The humidification and air cleaning apparatus of claim 1 , wherein the at least one spray nozzle comprises at least two spray nozzles that are respectively disposed to face different directions when viewed from a top view.

5. The humidification and air cleaning apparatus of claim 1 , wherein the visual body is disposed on a horizontal line of the at least one spray nozzle.

6. The humidification and air cleaning apparatus of claim 1 , wherein the inclination surface of the visual body is formed such that at least a portion of water forming the spray line is upwardly scattered.

7. The humidification and air cleaning apparatus of claim 1 , wherein the inclination surface of the visual body is inwardly formed from the outside of the water tank.

8. The humidification and air cleaning apparatus of claim 1 , wherein the visual body has the inside thereof formed to be wide at an upper side and narrow at a lower side thereof, and has an inner side surface thereof inclined.

9. The humidification and air cleaning apparatus of claim 1 , further comprising a display disposed on an outer side of the visual body, the display having a surface which is entirely visible from an external location of the humidification and air cleaning apparatus.

10. The humidification and air cleaning apparatus of claim 9 , wherein the display comprises an upper side surface formed to incline, and an inclination direction of the upper side surface and an inclination direction of the visual body cross each other.

11. The humidification and air cleaning apparatus of claim 9 , wherein the visual body is inclined such that a most outer side thereof is high and a most inner side thereof is low whereby an inclination direction of the visual body is defined according to an external diameter of the most outer side thereof being greater than an external diameter of the most inner side thereof, and the display is inclined such that a most inner side thereof is high and a most outer side thereof is low whereby an inclination direction of the display is defined according to an external diameter of the most inner side thereof being greater than an external diameter of the most outer side thereof.

12. The humidification and air cleaning apparatus of claim 9 , wherein the display comprises an upper side surface formed of a reflective material, and droplet formed on the visual body is reflected by or projected on a surface of the display.

13. The humidification and air cleaning apparatus of claim 1 , wherein a water repellent coating is formed on the inner side surface of the visual body.

14. The humidification and air cleaning apparatus of claim 1 , wherein the watering housing comprises:
a first watering housing spaced from an undersurface of an inner side of the water tank by a suction gap;
a second watering housing coupled 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, and
the at least one spray nozzle is formed on the second watering housing.

15. The humidification and air cleaning apparatus of claim 14 , further comprising a watering blade disposed in the second watering housing to collide with water sprayed from the at least one spray nozzle when the second water housing rotating.

16. The humidification and air cleaning apparatus of claim 14 , wherein the watering housing cover overlaps a portion of the at least one spray nozzle to interfere with water sprayed from the at least one spray nozzle.

17. The humidification and air cleaning apparatus of claim 14 , wherein:
each of the at least one spray nozzle sprays water in different directions, and
water sprayed from each of the at least one spray nozzle respectively forms each spray line.

18. The humidification and air cleaning apparatus of claim 17 , wherein the watering housing cover overlaps at least one of the at least one spray nozzle to interfere with water sprayed from the overlapped nozzle.

19. The humidification and air cleaning apparatus of claim 14 , wherein when water is sprayed from the at least one spray nozzle by the rotation of the watering housing, the level of water stored in the water tank is higher than the suction gap and is lower than the at least one spray nozzle.

20. A humidification and air cleaning apparatus comprising:
a water tank comprising a water tank body to store water and a visual body formed of a transparent material;
a watering housing disposed in the water tank and having a spray nozzle to spray water stored in the water tank body; and
a watering motor to rotate the watering housing,
wherein the spray nozzle sprays water to form at least one spray line on an inner side surface of the visual body,
wherein at least a portion of the visual body comprises an inclination surface that is inclined, and the spray line is formed on the inclination surface of the visual body.
