According to the embodiment, a toilet device includes a toilet, a flow channel, a wash water supply unit a sensing unit and a controller. The sensing unit is configured to sense whether or not the wash water is at a position lower than a full water level and higher than a sealing water level on a surface of a bowl of the toilet. The controller is configured to determine a clogging state of the toilet based on a sensing result of the sensing unit following the closing of the wash water supply unit. A sensing region of the sensing unit is a position on the surface of the bowl through which the wash water flowing in a vertical direction from a water discharge port of the flow channel to a bottom portion of the bowl passes after the wash water supply unit is closed.

Toilet device

According to an embodiment, a toilet device includes a detector configured to detect at least one of a water level inside a flush toilet or an indicator associated with the water level, a clog determiner determining a clog state of the flush toilet based on a detection result of the detector, and a controller determining, based on a determination result of the clog determiner, whether or not to prohibit a flushing water supply to the flush toilet. The controller sets a flush prohibition time at least after the flushing water supply to the flush toilet has ended. A flush operation for flushing the flush toilet not is accepted temporarily in the flush prohibition time. The clog determiner determines the clog state of the flush toilet based on the detection result of the detector within the flush prohibition time or directly after the flush prohibition time.

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.

Toilet device and toilet system

Provided is an automatic faucet using a radio wave sensor, which is capable of preventing erroneous stop of water spouting, with a simple configuration. The automatic faucet () has a radio wave propagation space, a radio wave emitting port (), and directivity setting device. The directivity setting device is configured to direct a radio wave being emitted from the radio wave emitting port (), in such a manner that, during a water stopping state, the emitted radio wave lies along a spouting direction (A) along which washing water is to be spouted from a spout port (), and, during a water spouting state, a part of the radio wave emitted disposed offset in a direction C, with respect to the spout port () interferes with a region of a peripheral surface of a stream (W) facing in the direction C.
