Nozzle for cleaner
A nozzle for a cleaner includes a nozzle housing including a suction flow path through which air including dust flows and at least a portion of which extends in a front and rear direction. First and second rotation cleaning units are arranged on the lower side of the nozzle housing to be spaced apart from each other in a lateral direction. Each of the first and second rotation cleaning units includes a rotation plate adapted for attachment of a mop. A first driving device including a first driving motor drives the first rotation cleaning unit and a second driving device including a second driving motor drives the second rotation cleaning unit. A water tank mounted on the nozzle stores water to be supplied to the mop.
1. A nozzle for a cleaner comprising:
a nozzle housing forming a suction flow path through which air including dust flows, wherein the suction flow path includes:
a first flow path extending in a first direction; and
a second flow path extending rearward in a second direction from a center portion of the first flow path;
a flow path forming portion disposed on a center portion of the nozzle housing so as to cover an upper of the suction flow path;
a first rotation plate and a second rotation plate arranged on a lower side of the nozzle housing and spaced apart from each other in the first direction, each of the first rotation plate and the second rotation plate configured to support a mop;
a first driving device including a first driving motor configured to drive the first rotation plate, the first driving motor being spaced apart from the flow path forming portion in the first direction; and
a second driving device including a second driving motor configured to drive the second rotation plate, the second driving motor being spaced apart from the flow path forming portion in the first direction so as to be disposed on an opposite position of the first motor.
2. The nozzle of claim 1 , wherein the flow path forming portion partitions a space in which the first driving device and the second driving device are positioned from the suction flow path.
3. The nozzle of claim 1 , wherein the flow path forming portion forms at least a portion of the suction flow path extending in the second direction, the second direction being perpendicular to the first direction.
4. The nozzle of claim 1 , wherein the flow path forming portion extends in a front and rear direction.
5. The nozzle of claim 4 , wherein the first driving motor and the second driving motor are symmetrically disposed with respect to the flow path forming portion.
6. The nozzle of claim 1 , wherein
the second direction is perpendicular to the first direction.
7. The nozzle of claim 6 , wherein the second flow path is formed along the flow path forming portion.
8. The nozzle of claim 7 , wherein the first flow path and the second flow path have an opening formed at a lower surface of the nozzle housing.
9. The nozzle of claim 7 , wherein a center line of the flow path forming portion is the same as or parallel to a center line of the second flow path.
10. The nozzle of claim 7 , wherein a center line of the flow path forming portion intersects a center line of the first flow path.
11. The nozzle of claim 1 , wherein a center line of the flow path forming portion is disposed between a first rotation center of the first rotation plate and a second rotation center of the second rotation plate.
12. The nozzle of claim 1 , wherein an axis of the first driving motor and an axis of the second driving motor are symmetrically disposed with respect to a center line of the flow path forming portion.
13. The nozzle of claim 12 , wherein the axis of the first driving motor and the axis of the second driving motor are positioned on the nozzle housing and disposed along an extension direction of the flow path forming portion.
14. The nozzle of claim 1 , wherein the nozzle housing includes:
a nozzle base on which the first driving motor and the second driving motor are located; and
a nozzle cover covering the first and second driving motors at an upper side of the nozzle base, and
wherein at least a portion of the flow path forming part is positioned between the nozzle base and the nozzle cover.
15. The nozzle of claim 14 , wherein the suction flow path is formed in the nozzle base.
16. The nozzle of claim 15 , wherein the nozzle base includes an inlet of the suction flow path.
17. The nozzle of claim 14 , further comprising a water tank disposed above the nozzle base, the water tank being configured to supply water to the first rotation plate and the second rotation plate.
18. The nozzle of claim 17 , wherein the water tank is symmetrically disposed with respect to the portion of the flow path.
19. The nozzle of claim 1 , wherein the flow path forming portion extends from a front part of the nozzle housing to a connection tube, the connection tube being configured to be coupled to a cleaner.
