A detection range specification member for a human body detection sensor is provided in a washroom and is configured to specify a detection range of a human body detection sensor having an infrared sensor body configured to detect a human body. The detection range specification member for the human body detection sensor includes a material that reduces transmission of infrared rays, and is provided so as to cover at least a part of the infrared sensor body. The detection range specification member for the human body detection sensor is a sheet member that is configured to allow installation on a sensor surface side of the infrared sensor body.

To collect excretion information indicating a content of excrement in a toilet bowl without having to ask a user of a toilet and prevent flushing of a foreign body other than the excrement, even when the foreign body is present in the toilet bowl.

The information processing system (1) includes an acquisition unit (1a) that acquires excretion information on the basis of imaging data captured by an image capture apparatus installed in such a way as to include, in an image capture range, an excretion range of excrement in a toilet bowl of a toilet, a generation unit (1b) that generates presentation information on the basis of the excretion information, an output unit (1c) that outputs the presentation information, and a washing control unit (1d) that controls a washing function of the toilet bowl. The acquisition unit (1a) acquires information that indicates whether a foreign body being an object other than feces and urine is included in the imaging data as a subject excluding the toilet bowl and washing liquid for the toilet bowl, as at least a part of the excretion information. When information including the foreign body is acquired, the washing control unit (1d) outputs a stop command for stopping the washing function to the toilet bowl side, and the generation unit (1b) generates alert information as at least a part of the presentation information.

A smart toilet (100) includes an information acquisition device (110) and a control device (120). The information acquisition device (110) is configured to acquire feature information of the smart toilet (100) in a working state, the feature information at least including voiceprint information and odor information, or voiceprint information, or odor information of a human body using the smart toilet (100). The control device (120) includes an identity recognition component (121) configured to recognize, according to the feature information, the identity of the human body using the smart toilet (100). An electric appliance system including the smart toilet (100) is further included.

A management system includes: a detection device including a main body that has a shape installable to a discharge port, electrodes that are provided in the main body and are detectors detecting a liquid, and a communication device that functions as a transmitter transmitting information regarding a detection result obtained by the detector; and an estimation device including a receiver that receives the information transmitted from the transmitter, and an estimator that estimates a discharge state of the liquid from the discharge port based on the information received by the receiver.

According to the embodiment, a toilet device includes a detector and a controller. The detector is detecting whether or not flush water is at a position lower than a full level and higher than a seal level at a surface of a bowl of a flush toilet. The controller is determining a clog state of the flush toilet based on a detection result of the detector after a flush water supplier is closed. The flush water supplier is located in a flow channel discharging flush water into the bowl. The position of the detection region of the detector at the surface of the bowl is separated from flush water flowing in a vertical direction from a water discharge port of the flow channel toward a bottom portion of the bowl after the flush water supplier is closed.

A touchless actuation system for a toilet includes a touchless sensor, a motor assembly, and a processing circuit. The touchless sensor is located within a closed reservoir of the toilet. The processing circuit is configured to receive a signal from the touchless sensor and to detect an object within a detection region based on the signal. The detection region is external to the closed reservoir. The processing circuit is configured to facilitate flushing of the toilet through interaction with the motor assembly when the object is detected.
