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, a rack guide configured to guide the rack, and a supporter supporting the nozzle unit so that the nozzle unit is slidable. The nozzle unit includes a washing nozzle curved to be upwardly convex. The supporter includes a nozzle placement part having an upper surface curved to be upwardly convex. The upper surface includes a top, a first inclined surface descending frontward from the top, and a second inclined surface descending backward from the top. The washing nozzle overlaps the top in a vertical direction when the washing nozzle is in a stored state.

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, the nozzle unit including a washing nozzle curved to be upwardly convex;   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;   a rack guide configured to guide the rack; and   a supporter supporting 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 upper surface including
 a top, 
 a first inclined surface descending frontward from the top, and 
 a second inclined surface descending backward from the top, 
   the washing nozzle overlapping the top in a vertical direction when the washing nozzle is in a stored state.   
     
     
         2 . The sanitary washing device according to  claim 1 , wherein
 a center of the nozzle unit in an extension direction of the nozzle unit is positioned further forward than the top when the washing nozzle is in the stored state, and   the extension direction of the nozzle unit is curved.   
     
     
         3 . The sanitary washing device according to  claim 1 , wherein
 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 being curved with a larger curvature than the first curved portion, 
   the drive motor is configured to move the rack by driving the rack at a first rotational speed when the rack is in a first state,   the drive motor is configured to move the rack by driving the rack at a second rotational speed when the rack is in a second state,   the rack is positioned further back in the second state than in the first state, and   the second rotational speed is less than the first rotational speed.
