Nozzle for cleaner
A nozzle for a cleaner has a nozzle housing, which has a nozzle base and a drain hole for discharging water from the nozzle housing. The nozzle also has a rotary cleaning unit disposed below the nozzle housing. The rotary cleaning unit has a rotation plate that can be attached to a mop. The nozzle has a driving unit that includes a driving motor for driving the rotary cleaning unit. The nozzle also has a control board for controlling the drive motor. In addition, the nozzle has a water tank detachably mounted on an upper side of the nozzle housing. The water tank stores water and supplies the water to the rotary cleaning unit.
1. A nozzle for a cleaner comprising:
a nozzle housing including a nozzle base and a nozzle cover coupled to an upper side of the nozzle base;
a rotary cleaning unit rotatably disposed below the nozzle base and including a plurality of rotation plates spaced apart from each other in a lateral direction of the nozzle housing, the plurality of rotation plates being configured to be attached to a mop;
a suction flow path provided in the nozzle housing to suck air containing dust and disposed in a front of the rotary cleaning unit;
a driving unit provided in the nozzle housing and including a driving motor for driving the plurality of rotation plates;
a water tank detachably mounted on an upper seating surface of the nozzle cover and including a coupling rib is formed to protrude from a front end of the water tank;
a water supply flow path provided in the nozzle housing and configured to supply water stored in the water tank to the plurality of rotation plates; and
a rib insertion hole formed in a front portion of the nozzle cover and forms a recessed space to insert the coupling rib into the nozzle cover,
wherein the rib insertion hole is positioned higher than a front end of the upper seating surface of the nozzle cover.
2. The nozzle of claim 1 , wherein the upper seating surface of the nozzle cover is recessed to accommodate a bottom of the water tank.
3. The nozzle of claim 1 , wherein, in a state where the water tank is mounted on the nozzle cover, a valve for supplying water from the water tank to a water pump is fixed to the seating surface of the nozzle cover.
4. The nozzle of claim 3 , wherein the valve is disposed behind the rib insertion hole.
5. The nozzle of claim 3 , wherein a sealer is disposed on the upper seating surface to prevent leakage from a vicinity of the valve.
6. The nozzle of claim 1 , wherein the rib insertion hole is formed to be spaced apart from the front end of the upper seating surface of the nozzle cover.
7. The nozzle of claim 1 , wherein the suction flow path includes:
a first suction flow path formed along at least a portion of a front end of the nozzle base; and
a second suction flow path extending in a front-rear direction from the first suction flow path.
8. The nozzle of claim 7 , wherein a control board for controlling the driving motor is disposed on the nozzle base, and
wherein at least a portion of the control board is disposed behind the driving motor.
9. The nozzle of claim 8 , wherein the nozzle base includes a support protrusion for supporting the control board away from a bottom of the nozzle base.
10. The nozzle of claim 7 , wherein the rib insertion hole is provided as a pair symmetrically disposed about the second suction flow path, respectively.
11. The nozzle of claim 9 , wherein the control board is disposed on one side based on the second suction flow path.
12. The nozzle of claim 11 , wherein a water pump provided on the water supply flow path is disposed on the opposite side to the control board with respect to the second suction flow path.
13. The nozzle of claim 7 , wherein the rib insertion hole is provided as a pair formed at positions spaced laterally around the second suction flow path.
14. The nozzle of claim 1 , wherein the nozzle base includes a drain hole for discharging the water introduced into the nozzle housing to the outside, and
wherein the drain hole is positioned to overlap the plurality of rotation plates in a vertical direction.
15. The nozzle of claim 1 , further comprising a blocking rib disposed below the upper seating surface of the nozzle cove so as to prevent water leaking through the rib insertion hole.
16. The nozzle of claim 1 , wherein the front end of the upper seating surface is disposed lower than a rear end of the upper seating surface of the nozzle cover.
17. The nozzle of claim 16 , wherein the upper seating surface of the nozzle cover is formed to have an inclination from the front end to the rear end.
18. The nozzle of claim 1 , wherein the rib insertion hole forms an opening in a direction toward a rear direction of the nozzle cover.
19. The nozzle of claim 18 , when the water tank is seated on the upper seating surface of the nozzle cover, the coupling rib of the water tank protrudes along a front direction of the nozzle cover.
20. The nozzle of claim 18 , wherein the rib insertion hole and the coupling rib are disposed to face each other.
