Sanitary washing device

Abstract

A sanitary washing device includes a casing, a nozzle unit configured to advance and retreat between the casing and a toilet, a flexible rack connected to the nozzle unit, a gear configured to engage the rack, a drive motor configured to advance and retract the nozzle unit by moving the rack via the gear, and a rack guide configured to guide the rack. The rack guide includes a first curved portion curved to be upwardly convex, and a second curved portion positioned further back than the first curved portion. The second curved portion includes a portion bent upward as the second curved portion extends backward.

What is claimed is: 
     
         1 . A sanitary washing device, comprising:
 a casing;   a nozzle unit configured to advance and retreat between the casing and a toilet;   a rack connected to the nozzle unit, the rack being flexible;   a gear configured to engage the rack;   a drive motor configured to advance and retract the nozzle unit by moving the rack via the gear; and   a rack guide configured to guide the rack,   the rack guide including
 a first curved portion curved to be upwardly convex, and 
 a second curved portion positioned further back than the first curved portion, the second curved portion including a portion bent upward as the second curved portion extends backward. 
   
     
     
         2 . The sanitary washing device according to  claim 1 , wherein
 a curvature of the second curved portion is greater than a curvature of the first curved portion.   
     
     
         3 . The sanitary washing device according to  claim 1 , wherein
 the nozzle unit includes a washing nozzle shaped so that the washing nozzle is curved along the first curved portion when the washing nozzle is in a stored state.   
     
     
         4 . The sanitary washing device according to  claim 3 , further comprising:
 a supporter configured to support the nozzle unit so that the nozzle unit is slidable,   the supporter including a nozzle placement part having an upper surface curved to be upwardly convex,   the washing nozzle being disposed above the upper surface of the nozzle placement part when the washing nozzle is in the stored state.   
     
     
         5 . The sanitary washing device according to  claim 4 , wherein
 the gear is positioned between the first curved portion and the second curved portion.
