Abstract

According to one embodiment, a sanitary washing apparatus includes a private part washing nozzle configured to wash a human body private part, a tube configured to supply water to the private part washing nozzle, an incoming water connection part connected to an upstream side of the tube and configured to supply water to the tube, a casing storing the private part washing nozzle, the tube, and the incoming water connection part, and a nozzle wash part configured to wash the private part washing nozzle. The private part washing nozzle is curved upward to be convex, and has a first region positioned frontward of the nozzle wash part in an advanced state in which the private part washing nozzle advances from the casing. The incoming water connection part is provided under the private part washing nozzle, and is rotatable.

First claim

What is claimed is:

1. A sanitary washing apparatus, comprising:
a private part washing nozzle configured to wash a human body private part;
a tube configured to supply water to the private part washing nozzle;
an incoming water connection part connected to an upstream side of the tube and configured to supply water to the tube;
a casing storing the private part washing nozzle, the tube, and the incoming water connection part; and
a nozzle wash part configured to wash the private part washing nozzle,
the private part washing nozzle being curved upward to be convex, and advancing and retreating along a virtual orbit having an arc shape,
the private part washing nozzle having a first region positioned frontward of the nozzle wash part in an advanced state in which the private part washing nozzle advances from the casing,
in a stored state in which the private part washing nozzle is stored in an interior of the casing, a back end of the first region being positioned at a top positioned directly above a curvature center of an arc of the virtual orbit, or frontward of the top,
the incoming water connection part being provided under the private part washing nozzle, and being rotatable in accordance with advance and retreat action of the private part washing nozzle,
the incoming water connection part being rotatable from a first rotation position in the stored state to a second rotation position in accordance with advance of the private part washing nozzle, and
a connection portion of the incoming water connection part and the tube being positioned at a backward side of the incoming water connection part in the first rotation position and being positioned at an upward side of the incoming water connection part in the second rotation position.

2. The sanitary washing apparatus according to claim 1 , wherein
in the stored state, a back end of the private part washing nozzle is positioned at the top or frontward of the top.

3. The sanitary washing apparatus according to claim 1 , wherein
the incoming water connection part is provided to be substantially horizontal or inclined upward from upstream toward downstream.

4. The sanitary washing apparatus according to claim 3 , wherein
a back end of the incoming water connection part is positioned frontward of the top.

5. The sanitary washing apparatus according to claim 1 , wherein
the private part washing nozzle includes a first cylinder portion advancing from the casing and a second cylinder portion advancing from the first cylinder portion,
the second cylinder portion includes a water discharge port, and
in the stored state, the water discharge port is stored in an interior of the first cylinder portion.

6. The sanitary washing apparatus according to claim 1 , further comprising:
a cable rack for advancing the private part washing nozzle,
the cable rack being curved in same direction as the virtual orbit in a side surface view.

7. The sanitary washing apparatus according to claim 1 , wherein
the tube includes a first part positioned outside the private part washing nozzle,
in the stored state, at least a portion of the first part is curved in same direction as the virtual orbit in a side surface view, and
in the advanced state, at least a portion of the first part is curved in same direction as the virtual orbit in a side surface view.

8. The sanitary washing apparatus according to claim 7 , wherein
the incoming water connection part is provided at a position overlapping the private part washing nozzle in a top view.

9. The sanitary washing apparatus according to claim 7 , wherein
the private part washing nozzle includes a guide which makes the tube curved downward.

10. The sanitary washing apparatus according to claim 9 , wherein
the private part washing nozzle includes a first cylinder portion advancing from the casing and a second cylinder portion advancing from the first cylinder portion, and
the guide is the first cylinder portion.

11. The sanitary washing apparatus according to claim 7 , further comprising:
a nozzle drive part which makes the private part washing nozzle advance and retreat,
at least a portion of the nozzle drive part being provided under the washing nozzle.
