Description

図４、図５に示すように床下に排水管６２（排水細管６２３、排水枝管６２２）を設けた場合、この排水管６２に流量計や水位計を設け、この排水管６２（排水細管６２３、排水枝管６２２）に排水が流れたことを流量計や水位計検出した場合に漏水が有ると検出して制御装置６に入力しても良い。これにより、便器等から床に水が溢れて排水管６２（排水細管６２３、排水枝管６２２）に流れた場合に、漏水として検出できる。なお、床下に排水管６２に設けた流量計や水位計は、床に水を流して掃除する際は漏水の検出をＯＦＦにし、掃除以外で排水が流れて水位や水量を検出した場合に漏水として検出しても良い。 As shown in FIGS. 4 and 5, when a drain pipe 62 (drain narrow pipe 623, drain branch 622) is provided under the floor, a flow meter and a water level meter are provided on the drain pipe 62, and the drain pipe 62 (drain narrow pipe 623). When the flow meter or the water level meter detects that drainage has flowed into the drain branch 622), it may be detected that there is water leakage and input to the control device 6. Thereby, when water overflows from a toilet bowl or the like to the floor and flows into the drain pipe 62 (drain narrow pipe 623, drain branch 622), it can be detected as water leakage. It should be noted that the flow meter and water level meter provided in the drain pipe 62 under the floor turn off the detection of water leakage when cleaning by flowing water through the floor, and water leakage occurs when the drainage flows other than cleaning and the water level and water volume are detected. May be detected as

Claims

A water supply valve for switching between water supply and water supply to the toilet via a water supply pipe connected to an external water supply source;
A sensor for detecting a state of water supply or drainage of the toilet;
Water leakage determination means for determining water leakage based on the detection result of the sensor;
Water supply control means for controlling the water supply valve to stop water based on the determination result of the water leakage;
A communication unit connected to a network and transmitting information on the water leakage to a predetermined computer via the network based on the determination result of the water leakage;
Having a toilet system.

The toilet system according to claim 1, wherein the sensor detects the presence of water on an outer surface of a water supply pipe that supplies water to the toilet or a drain pipe that discharges water from the toilet, or on a floor surface in the toilet.

The sensor includes a pair of electrodes that are electrically spaced apart from each other, and detects a change in electrical characteristics between the electrodes when the water leaks into a gap between the electrodes as a state of water leakage. ,
The water leakage determination means determines that there is water leakage when a change in the electrical characteristics by the sensor exceeds a first threshold,
The toilet system according to claim 1 or 2, wherein when it is determined that there is water leakage, the communication unit transmits information on the water leakage.

The water leakage determination means determines that the water leakage is greater than or equal to a predetermined amount when the change in the electrical characteristics by the sensor exceeds a second threshold,
The toilet system according to claim 3, wherein when it is determined that there is a predetermined amount or more of the water leakage, the water supply control means controls the water supply valve to stop water.

The toilet system according to claim 4, wherein the water leakage determination means determines the urgency based on a time from when the change in the electrical characteristics by the sensor exceeds a first threshold to when it exceeds a second threshold.

Comprising a flush valve that releases the wash water the feedwater pipe or al flight instrument,
The water supply control means controls to close the water supply valve at a predetermined inspection timing, and checks whether the water supply valve operates normally based on whether the flush valve is opened and wash water flows. The toilet system according to any one of claims 1 to 5.
