The water supply connection part connects the water supply hose and the valve unit. The casing has a concave portion recessed upward from a bottom surface of the casing. The concave portion has an upper surface and a side surface extending from the upper surface and facing backward or sideward. The water supply connection part is provided on the side surface of the concave portion.

According to one embodiment, a sensor device includes a transmitter part, a receiver part, a signal generation part, and a determination part. The transmitter part is configured to emit a radio wave outside as a transmission wave. The receiver part is configured to receive a reflection wave reflected by an object as a reception wave. The signal generation part is configured to generate a first output signal generated based on the transmission wave and the reception wave, a second output signal provided with a phase different from that of the first output signal, and a third output signal generated based on the first output signal and the second output signal. The determination part is configured to determine presence or absence of an object based on the first output signal, the second output signal, and the third output signal.

A sanitary device includes a radio wave sensor, a control section. The radio wave sensor is configured to obtain information on a sensing target by a reflection wave of an emitted radio wave. The control section is configured to control operation of an instrument based on a sensing signal including a first signal and a second signal outputted from the radio wave sensor. Difference between a phase of the second signal and a phase of the first signal is not less than 60° and not more than 120°. The control section is configured to determine presence or absence of the sensing target based on sum of square of difference between a value of the first signal and a first reference value and square of difference between a value of the second signal and a second reference value.

A toilet management system includes a toilet bowl device installed in a toilet room, a management device configured to manage a use situation of the toilet bowl device, and a communication device configured to transmit use situation information related to the use situation of the toilet bowl device to the management device. The management device includes an acquirer configured to acquire the use situation information from the communication device, and an abnormality detector configured to detect an abnormality of the toilet bowl device or a facility or equipment installed inside or around the toilet room when the use situation information acquired by the acquirer matches a predetermined condition.

A heating system for a toilet seat for warming the toilet seat is presented. The heating system is useful for providing a comfortable warm seat for a user when they are using a toilet. Also, the heating system is useful for providing a lighted guide of the toilet for the user.

A heating seat ring includes a lower seat ring and an upper seat ring. The lower seat ring is made of a hard material, the upper seat ring is made of a soft material, and the upper seat ring is disposed on the lower seat ring. The upper seat ring and the lower seat ring are matched and connected to form a heating cavity. A heating assembly is disposed in the heating cavity, and the heating assembly is configured to emit heat to heat the upper seat ring. The heating assembly emits heat to heat the upper seat ring, so that a user feels more comfortable when sitting on the heating seat ring.

A toilet includes a base, a cover, and a seat. The seat is rotatably coupled to the base, and the cover is rotatably coupled to the seat. The cover and the seat define an angled axis that is oriented upward and forward toward a front end of the base. The cover and the seat are each configured to rotate about the angled axis between a lowered position in which the cover and the seat are located adjacent the base and a stowed position in which the cover and the seat are oriented in an upward direction.

A sanitary washing device includes a nozzle, a valve unit, a casing, and a toilet seat. The nozzle is configured to discharge water toward an ano-genital region of a human body. The valve unit is provided on a pipe line between a water supply source and the nozzle, and includes an electromagnetic valve. The casing stores the nozzle and the valve unit. The casing includes a low portion positioned below the toilet, and a high portion positioned backward of the low portion. A length in a vertical direction of the high portion is greater than a length in the vertical direction of the low portion. The valve unit is disposed in the low portion. A length in the vertical direction of the valve unit is less than a length in a longitudinal direction, and less than a length in a lateral direction.

A sanitary washing device includes a nozzle, a valve unit, a casing, and a toilet seat. The nozzle is configured to discharge water toward an ano-genital region of a human body. The valve unit is provided on a pipe line between a water supply source and the nozzle. The valve unit includes an electromagnetic valve. The casing stores the nozzle and the valve unit. The toilet seat is pivotally supported to be rotatable with respect to the casing. A heater is provided inside the toilet seat. At least a portion of the valve unit is disposed below the toilet seat.
