According to the embodiment, a toilet seat device includes a toilet seat and a biological sensor. The toilet seat that is formed of a resin material and includes a seating part on which a user is seated, and a bottom surface part facing the seating part. The biological sensor that is of an optical type, is positioned inside the toilet seat, and detects biological information of the user seated on the seating part. The seating part includes a thick portion and a thin portion. The thin portion is thinner than the thick portion. The biological sensor is located at a back surface side of the thin portion. The thick portion and the thin portion are formed as a continuous body. The thin portion has a thickness that can transmit irradiated light irradiated from the biological sensor and reflected light reflected from the user seated on the seating part.

Toilet seat device

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

Sanitary washing device

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

A toilet seat device includes a main part, a toilet seat, a load sensor, a controller, and a memory. The toilet seat includes a seating part where a user is seated, and a support leg part supporting a load applied to the seating part. The load sensor is provided in the support leg part and detects the load applied to the support leg part. The controller performs at least a body weight measurement of the user based on a detection result of the load sensor. The controller includes a register mode and a normal-use mode in the body weight measurement. The register mode includes determining an estimated value for estimating the total body weight of the user from the seated load. The normal-use mode includes estimating a load value relating to the total body weight of the user based on the estimated value.

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 toilet apparatus includes a toilet, a bowl configured to receive solid waste being formed in the toilet, the bowl being hydrophilic; a spray unit configured to spray at least one selected from water and hypochlorous acid water onto a surface of the bowl; a detection unit configured to detect a state of use of the toilet; and a control unit configured to spray at least one selected from the water and the hypochlorous acid water from the spray unit before the use and to spray the hypochlorous acid water from the spray unit after the use. The cleanliness of the bowl surface of a toilet can be maintained by suppressing the affixation of solid waste and the propagation of bacteria caused by oil.

Toilet apparatus

A sanitary washing device includes: a nozzle including a water discharge port and configured to squirt water from the water discharge port to wash user's human private parts; a flow channel configured to supply the water to the water discharge port; a water supply device configured to supply the water; a sterilizing water producing device provided midway along the flow channel and being operable to produce sterilizing water; and a controller configured to perform control for retaining the sterilizing water produced by the sterilizing water producing device for a prescribed time in the flow channel, and then draining the sterilizing water out of the flow channel.

A sanitary washing apparatus includes a nozzle having a water discharge port, the nozzle being configured to wash a human private part by squirting water from the water discharge port, a flow channel configured to supply the water to the nozzle, a sterilizing water supply unit provided partway through the flow channel, the sterilizing water supply unit being capable of supplying sterilizing water, and a control unit configured to execute a physical washing process of washing the nozzle using water and a sterilizing process of sterilizing the nozzle using the sterilizing water after the washing the human private part. The washing nozzle can be sterilized more efficiently or a user's sense of cleanliness regarding the washing nozzle can be improved.

A sanitary washing device, includes: a nozzle including a water discharge port and configured to squirt water from the water discharge port to wash a human private part; a water conduit configured to guide water supplied from a water supply source to the nozzle; a sterilizing water supply part provided midway along the water conduit and capable of producing sterilizing water; a flow rate adjusting part configured to adjust flow rate of water flowing in the sterilizing water supply part; a flow state varying part configured to vary flow state of water flowing in the water conduit; and a controller configured to control the flow state varying part to vary the flow state of the water flowing in the water conduit when producing the sterilizing water by the sterilizing water supply part in a state in which the controller controls the flow rate adjusting part to make the flow rate of the water flowing in the sterilizing water supply part lower than maximum flow rate.
