Abstract

A sanitary washing device includes a private part washing nozzle, a casing, a sterilizing water generator, and an illuminator. The private part washing nozzle discharges water toward a private part of a user in a state of the private part washing nozzle is advanced into a toilet. The casing includes a nozzle storage part configured to store an entirety of the private part washing nozzle in a state of the private part washing nozzle is retracted. The sterilizing water generator generates sterilizing water supplied to the private part washing nozzle and the nozzle storage part. The illuminator irradiates sterilizing light into the nozzle storage part. The sterilizing light has a sterilizing action. The illuminator irradiates the sterilizing light toward a residual water occurrence portion at which the sterilizing water supplied into the nozzle storage part remains.

First claim

What is claimed is:

1. A sanitary washing device, comprising:
a private part washing nozzle discharging water toward a private part of a user in a state of the private part washing nozzle being advanced into a toilet;
a casing including a nozzle storage part configured to store an entirety of the private part washing nozzle in a state of the private part washing nozzle being retracted;
a sterilizing water generator generating sterilizing water supplied to the private part washing nozzle and the nozzle storage part; and
an illuminator irradiating sterilizing light into the nozzle storage part,
the sterilizing light having a sterilizing action,
the illuminator irradiating the sterilizing light toward a residual water occurrence portion at which the sterilizing water supplied into the nozzle storage part remains.

2. The device according to claim 1 , wherein
the sterilizing water generator supplies the sterilizing water toward a water discharge port of the private part washing nozzle.

3. The device according to claim 1 , further comprising:
a water discharger discharging the sterilizing water toward the private part washing nozzle,
the sterilizing water generator supplying the sterilizing water toward the water discharger.

4. The device according to claim 1 , wherein
the residual water occurrence portion includes a front end side of a bottom portion of the nozzle storage part.

5. The device according to claim 1 , wherein
the nozzle storage part includes a nozzle lid configured to open and close an opening provided in a front end of the nozzle storage part, and
the residual water occurrence portion includes a lower end side of an inner surface of the nozzle lid.

6. The device according to claim 1 , wherein
at least a part of the illuminator is located further frontward than a front surface of the private part washing nozzle in the state of the private part washing nozzle being retracted.

7. The device according to claim 1 , wherein
at least a part of the illuminator is located lower than a center of a front surface of the private part washing nozzle in the state of the private part washing nozzle being retracted.

8. The device according to claim 7 , wherein
at least a part of the illuminator is located higher than a lower end of a front surface of the private part washing nozzle in the state of the private part washing nozzle being retracted.

9. The device according to claim 1 , wherein
the illuminator is located at one lateral-direction side of the nozzle storage part and irradiates sterilizing light toward an other lateral-direction side of the nozzle storage part.

10. The device according to claim 9 , wherein
the nozzle storage part includes a reflective material on the other lateral-direction side, the reflective material reflecting sterilizing light, and
the illuminator irradiates sterilizing light on the residual water occurrence portion by causing the sterilizing light to be reflected by the reflective material.
