Disclosed is a hypochlorous acid generating electrode that is substantially free from rhodium, which is comparable in performance to a rhodium-containing electrode and is more durable than the rhodium-containing electrode. The electrode to be used for generating hypochlorous acid by electrolyzing water that contains a chloride ion has excellent hypochlorous acid water generation ability and durability, in which the electrode has an electrode substrate comprising titanium or titanium alloy, and a composite layer that is electrically connected with the electrode substrate and that contains iridium or a compound thereof, tantalum or a compound thereof, and ruthenium or a compound thereof and/or platinum, and does not contain rhodium oxide.

Hypochlorous acid generating electrode

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.

Sanitary washing device

A sanitary washing device includes a nozzle, a casing, an illuminator, and a controller. The nozzle discharges water toward a private part of a user in a state of the nozzle is advanced into a toilet. The casing includes a nozzle storage part configured to store an entirety of the nozzle in a state of the nozzle is retracted. The illuminator irradiates sterilizing light into the nozzle storage part. The sterilizing light has a sterilizing action. The controller controls the illuminator. The controller includes a first irradiation mode of causing sterilizing light irradiated from the illuminator to be irradiated toward an outer circumferential surface of the nozzle. The controller includes a second irradiation mode of causing sterilizing light irradiated from the same illuminator as the first irradiation mode to be irradiated toward an inner wall of the nozzle storage part.

A sanitary washing device includes a nozzle, a drive device, a casing, a nozzle lid, and an illuminator. The casing includes a nozzle container. The nozzle lid is provided to be openable and closable with respect to an opening provided at a front end of the nozzle container. The nozzle lid is in a closed state in which the opening is closed when the entirety of the nozzle is stored in the nozzle container. The illuminator irradiates sterilizing light into an interior of the nozzle container. The sterilizing light has a sterilizing effect. At least one of the nozzle lid or a vicinity of the nozzle lid is luminous in a state of being visible to the user when the nozzle lid is in the closed state and the sterilizing light from the illuminator is irradiated into the interior of the nozzle container.

The toilet device includes a toiletand a sanitary washing devicemounted on the toilet. The sanitary washing deviceincludes a nozzle, a casing, a toilet seat, a toilet lid, and an illuminator. When the user operates an operation partbuilt into the interior of the casing, the nozzleis advanced into the bowlof the toilet. The casingincludes a nozzle containerthat can store the entire nozzle. The illuminatorirradiates sterilizing light which is light having a sterilizing action. The illuminatorirradiates the sterilizing light L directly on the front surfaceof the nozzleand/or the partof the bottom surface partpositioned below the front surface

According to an aspect of the present invention, a toilet device includes: a washing unit washing a surface of a bowl in a toilet bowl; a water supplying unit supplying washing water to the washing unit; a silicic acid polymerization inhibiting unit adding inhibitor for silicic acid polymerization to the washing water left on the surface of the bowl after the washing of the bowl, the inhibitor inhibiting polymerization of silicic acid component in the washing water left on the surface of the bowl; and a control portion executing a control starting an operation of the silicic acid polymerization inhibiting unit before the surface of the bowl is evaporated.

Toilet device

According to one embodiment, a sanitary washing apparatus includes: a nozzle including a jetting port and configured to squirt water from the jetting port to wash a user's body; a flow channel configured to guide water supplied from a water supply source to the jetting port; an electrolytic cell provided midway along the flow channel and being operable to produce sterilizing water; a heating device provided on the flow channel on upstream side of the electrolytic cell; a nozzle cleaning device configured to clean or sterilize the nozzle with the water heated by the heating device or the sterilizing water produced by the electrolytic cell; and a controller configured to perform control for stopping energization of the heating device or reducing an amount of energization of the heating device when energizing the electrolytic cell.

Sanitary washing apparatus

According to an aspect of the invention, a sanitary washing apparatus, characterized by: a nozzle being configured to wash a body of a user by squirting water from a water discharge port; a flow channel configured to guide water supplied from a water supply source toward the water discharge port; an electrolytic cell provided at an intermediate portion of the flow channel, the electrolytic cell being capable of producing sterilizing water; and a nozzle wash unit configured to wash or sterilize the nozzle with the sterilizing water produced by the electrolytic cell, a contraction portion being formed downstream from the electrolytic cell, a flow channel cross-sectional area being smaller at the contraction portion than upstream from the electrolytic cell, a strainer being disposed in the flow channel further downstream from the contraction portion. Clogging of the flow channel due to scale can be suppressed.
