Title:
PIPE DEVICE AND CLEANING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/189681
Kind Code:
A1
Abstract:
In a cleaning/drying mechanism (150), a flow switch (186) is provided to a drainage canal (184), said flow switch (186) outputting a sensor value that is an ON sensor value, which indicates that a fluid is flowing inside a pipe (184), or an OFF sensor value, which indicates that a fluid is not flowing inside the pipe (184). This sensor, i.e. the flow switch (186), is relatively inexpensive as a result of having a simple structure. Within a set amount of time from the time that a pressurizing pump (190) starts operating, it is determined whether an ON sensor value is being outputted by the flow switch (186). At such time, if an ON sensor value is outputted during the set amount of time, it is determined that a fluid is flowing in the pipe (184); if an ON sensor value is not outputted during the set amount of time, it is determined that a fluid is not flowing in the pipe (184). As a result, it is possible to monitor the flow of a fluid in the pipe (184) solely via the provision of one relatively inexpensive sensor.
