The fluid outlet 413 may be connected to the second storage space 411. The water stored in the second storage space 411 may be discharged to the fluid transfer pipe 420 through the fluid discharge port 413. [ The fluid discharge ports 413 may be disposed on both sides of the coupling tank 410, respectively. Specifically, one fluid outlet 413 may be disposed on the other side of the other fluid outlet 413 about the vertical axis of rotation A 1 . As another example, three or more fluid outlets 413 may be disposed on the outer circumferential surface of the coupling tank 410. The amount of water jetted from the nozzle 431 can be adjusted according to the number and size of the fluid discharge ports 413.

One end of the bending portion 421 may be coupled to the fluid discharge port 413 and the other end of the bending portion 421 may be coupled to the outer peripheral surface of the one end of the straight pipe portion 423. The bending portion 421 may have a shape that extends in the radial direction about the vertical rotation axis A 1 at the fluid outlet 413 and curves upward. For example, the bending portion 421 may be formed in an "a" shape. The other end of the bending portion 421 may be coupled to the outer peripheral surface of the one end of the straight pipe portion 423 and the other end of the straight pipe portion 423 may be coupled to the end of the nozzle portion 430. The straight pipe portion 423 may have a horizontally extending shape. The fluid transfer pipe 420 may be formed in a " C "shape together with the nozzle portion 430.

The third guide projection may be arranged so that the central axis of the third guide projection coincides with the horizontal rotation axis (A 2 ). The water transferred through the fluid transfer pipe 420 may be supplied to the nozzle unit 430 coupled to the straight pipe portion 423. Therefore, the annular second lip seal (L 2 ) as well as the bearing B is interposed in the connecting portion between the straight pipe portion 423 and the nozzle portion 430 so that the straight pipe portion 423 and the nozzle portion 430 can be prevented from leaking. Second ripssil (lip seal) (L 2) may be arranged to the central axis of the second ripssil (lip seal) (L 2) match the horizontal axis of rotation (A 2). The second lip seal (L 2 ) may be a Teflon rotary lip seal.

The water supplied to the nozzle unit 430 may be injected in the radial direction of the nozzle unit 430 through the nozzle 431. [ For reference, the movement path of the water is indicated by an arrow in Fig.

The nozzle unit 430 can rotate within a range of 180 degrees around the horizontal rotation axis A 2 through the control of the second driving motor 520. In this case, the nozzle 431 can maintain the state that the nozzle 431 is disposed above the nozzle unit 430, so that the water can be sprayed upward or upward.

The support portion 440 can be detachably coupled to the upper surface of the fixed cover 300 and can support the straight pipe portion 423. The support portion 440 may rotatably support the nozzle portion 430 instead of the straight pipe portion 423. The support portion 440 can reduce the vibration generated in the nozzle portion 430 and the fluid transfer pipe 420.

The driving unit 500 may provide power required for rotating the housing 200 and the nozzle unit 430.

The driving unit 500 may be disposed in the first accommodation space 210. As a result, the driving unit 500 is protected by the housing 200, so that even if the water leaks out between the fluid transfer device, for example, the input tank 400 and the coupling tank 410 due to an unintended hydraulic pressure rise, It is possible to prevent a failure in the battery 500. The first storage space 210 is provided with various sensors and control devices as well as an electric supply device for supplying electricity to the LED lamp installed in the housing 200 and the nozzle 431 .
