Abstract

The toilet device includes a toilet 800 and a sanitary washing device 100 mounted on the toilet 800 . The sanitary washing device 100 includes a nozzle 473 , a casing 400 , a toilet seat 200 , a toilet lid 300 , and an illuminator 700 . When the user operates an operation part 500 built into the interior of the casing 400 , the nozzle 473 is advanced into the bowl 801 of the toilet 800 . The casing 400 includes a nozzle container 480 that can store the entire nozzle 473 . The illuminator 700 irradiates sterilizing light which is light having a sterilizing action. The illuminator 700 irradiates the sterilizing light L directly on the front surface 473 a of the nozzle 473 and/or the part 480 c of the bottom surface part 480 b positioned below the front surface 473 a.

First claim

What is claimed is:

1. A sanitary washing device, comprising:
a private part wash nozzle tilted downward toward a front side, the private part wash nozzle having a water discharge hole discharging washing water toward a private part of a user;
a nozzle motor causing the private part wash nozzle to advance and retract;
a casing including a nozzle container configured to store an entirety of the private part wash nozzle in a state in which the private part wash nozzle is retracted; and
an illuminator irradiating sterilizing light, the sterilizing light being light having a sterilizing action,
the illuminator irradiating the sterilizing light on at least a front surface of the private part wash nozzle and a part of a bottom surface part of the nozzle container positioned below the front surface.

2. The device according to claim 1 , wherein at least a part of the illuminator is provided frontward of the front surface of the private part wash nozzle to cause an average illuminance of the sterilizing light on the front surface and a part of the nozzle container positioned frontward of the front surface to be larger than an average illuminance of the sterilizing light on an outer perimeter surface of the private part wash nozzle.

3. The device according to claim 1 , wherein at least a part of the illuminator is provided frontward of the front surface of the private part wash nozzle to cause an irradiation area of the sterilizing light on the front surface and a part of the nozzle container positioned frontward of the front surface to be wider than an irradiation area of the sterilizing light on an outer perimeter surface of the private part wash nozzle.

4. The device according to claim 1 , further comprising a nozzle lid provided to be openable and closable with respect to an opening provided at a front end of the nozzle container, the nozzle lid causing the nozzle container to be open in a state in which the private part wash nozzle is advanced and causing the nozzle container to be closed in a state in which the entirety of the private part wash nozzle is stored inside the nozzle container,
the nozzle lid having a back surface positioned on the nozzle container side,
at least a part of the back surface being formed of a reflective material,
the illuminator directly irradiating at least a part of the sterilizing light on the back surface of the nozzle lid in a state in which the nozzle lid is closed.

5. The device according to claim 4 , wherein the illuminator is provided in a vicinity of the back surface of the nozzle lid to cause an irradiation area of the sterilizing light directly irradiated on the back surface of the nozzle lid to be wider than an irradiation area of the sterilizing light directly irradiated on a part of the nozzle lid other than the back surface.

6. The device according to claim 4 , wherein
the sterilizing light includes reflected light reflected by the nozzle lid, and direct light not reflected by the nozzle lid, and
the illuminator is disposed at a position to cause the direct light to be irradiated on a front end part of the bottom surface part of the nozzle container.

7. The device according to claim 6 , wherein the illuminator is disposed to cause the direct light and the reflected light to be irradiated on the front end part of the bottom surface part.

8. The device according to claim 4 , wherein the back surface of the nozzle lid is formed in a curved configuration to cause reflected light to diffuse.

9. The device according to claim 4 , wherein
a nozzle washer is provided at a front end part vicinity of the private part wash nozzle,
the nozzle washer has a nozzle wash hole discharging washing water onto an outer surface of the private part wash nozzle, and
the nozzle washer is formed of a transmissive material transmitting the sterilizing light.

10. The device according to claim 9 , wherein
the nozzle washer includes a scattering agent to cause the sterilizing light to diffuse when being transmitted, and
at least a part of the nozzle washer is disposed frontward of the front surface of the private part wash nozzle in a state in which the entirety of the private part wash nozzle is stored inside the nozzle container.

11. The device according to claim 10 , wherein the nozzle washer is moved in a state in which the illuminator is operated.

12. The device according to claim 11 , wherein the nozzle washer is moved without opening the nozzle lid in the state in which the illuminator is operated.
