wherein the valve operating unit is disposed at a position spaced apart from the recessed space.
2 . The nozzle of claim 1 , wherein the valve operating unit is disposed at a position lower than the recessed space.
3 . The nozzle of claim 2 , wherein the valve operating unit is disposed on a front portion of the lower surface of the nozzle cover.
4 . The nozzle of claim 1 , further comprising a control board disposed in the inner space formed by the nozzle base and the nozzle cover to control the driving device,
wherein the control board is disposed to be spaced apart from the driving device.
5 . The nozzle of claim 1 , further comprising a water supply flow path provided in the inner space formed by the nozzle base and the nozzle cover to supply water stored in the water tank to the rotation plate.
6 . The nozzle of claim 5 , wherein the water supply flow path includes a water pump disposed at a position spaced apart from the recessed space.
7 . The nozzle of claim 6 , wherein the water pump is disposed at one side of the suction flow path.
8 . The nozzle of claim 1 , wherein the water tank forms a receiving space corresponding to the recessed space in a vertical direction of the nozzle housing.
9 . The nozzle of claim 1 , wherein the recessed space has a symmetrical shape with respect to a center of the nozzle housing.
10 . The nozzle of claim 1 , wherein the water tank forming an outer appearance of the nozzle.
11 . The nozzle of claim 1 , wherein the valve operating unit is coupled to a lower side of the nozzle cover, and
wherein a portion of the valve operating unit configured to protrude upward through the nozzle cover.
12 . The nozzle of claim 1 , wherein the valve operating unit protruding upward is introduced in the water tank through a discharge port of the water tank, when the water tank is seated on the nozzle cover.
13 . The nozzle of claim 12 , wherein the valve operating unit is disposed at a position facing the discharge port of the water tank.
14 . The nozzle of claim 12 , wherein the nozzle cover is provided with a sealer for preventing water discharged from the water tank from leaking from a vicinity of the valve operating unit, and
wherein the nozzle cover further includes a water passage opening formed at a position corresponding to the discharge port of the water tank.
15 . The nozzle of claim 14 , wherein the sealer is coupled to the lower surface of the nozzle cover and the valve operating unit is coupled to the lower surface of the nozzle cover.
16 . The nozzle of claim 14 , wherein the sealer includes a hole formed at a position corresponding to the water passage opening.
17 . The nozzle of claim 14 , wherein the sealer further includes a coupling protrusion formed around the hole and coupled to the lower surface of the nozzle cover.
