Nozzle Assembly For Bidet

Abstract

The present invention provides a nozzle assembly for a bidet, the nozzle assembly comprising: a nozzle unit which moves along a curved line and comprises a water supply hose connected to a water supply source; and a driving unit having a winding member for rotating/driving such that the length of extension of the nozzle unit is adjusted, the driving unit guaranteeing that the nozzle unit moves along a curved line, where the length of extension of the nozzle unit is adjusted in multiple steps, and the withdrawing rotation angle, by which the winding member rotates in order to change the length of extension of the nozzle unit from one of the steps to the adjacent upper step, is different in each step. The length of extension of the nozzle unit can be adjusted such that the interval of water ejection positions is constant.

1 . A nozzle assembly for a bidet, the nozzle assembly comprising:
 a nozzle unit making a curved movement and including a water supply hose connected to a water source; and   a driving unit having a winding member rotatably driven to adjust a length of extension of the nozzle unit and driving the nozzle unit to make a curved movement,   wherein the length of extension of the nozzle unit is adjusted by stages, and   a exit-out rotation angle at which the winding member rotates to change the length of extension of the nozzle unit from any one step to an adjacent higher step is different in each step.   
     
     
         2 . The nozzle assembly of  claim 1 , wherein the nozzle unit includes a cylinder member having a curved shape with a hollow formed therein, and
 the water supply hose is disposed in the hollow.   
     
     
         3 . The nozzle assembly of  claim 1 , wherein the nozzle unit is mounted on an upper portion of the movement guide member provided to correspond to a shape of the nozzle unit, and makes a curved movement. 
     
     
         4 . The nozzle assembly of  claim 3 , wherein the movement guide member has a curved shape. 
     
     
         5 . The nozzle assembly of  claim 1 , wherein a length of extension of the nozzle unit is increased from a lower step to a higher step. 
     
     
         6 . The nozzle assembly of  claim 1 , wherein a lead-in rotation angle at which the winding member rotates to change the length of extension of the nozzle unit from the adjacent higher step to the any one step is the opposite in direction to the exit-out rotation angle direction and has the same value. 
     
     
         7 . The nozzle assembly of  claim 1 , wherein the exit-out rotation angle is reduced in a direction toward a higher step. 
     
     
         8 . The nozzle assembly of  claim 7 , wherein a decrease of the exit-out rotation angle is reduced in a direction toward a higher step. 
     
     
         9 . The nozzle assembly of  claim 1 , wherein
 the driving unit includes:
 a connection member having one side fixedly coupled to the nozzle unit and the other side connected to the winding member; and 
 a driving motor connected to the winding member to provide rotational force to the winding member. 
   
     
     
         10 . The nozzle assembly of  claim 9 , wherein the connection member is provided as a belt gear having one side fixedly coupled to a lower end of the nozzle unit.
