Abstract

PROBLEM TO BE SOLVED: To remove the clogging of a filter perfectly by detecting the clogging of the filter for removing refuse in a fluid in an apparatus for circulating bath water in a step when the deterioration of the performance hardly occurs and in a timing satisfactory to the use for bath or the lie. SOLUTION: A relation of the change of the output of a flow rate detecting means to the driving time of a pressurizing means is grasped by measuring and calculating the driving time of the pressurizing means in a fluid control apparatus constituted of a flow passage, the filter, the flow rate detecting means and a control part having a timing means and fetching the output of the flow rate detecting means. The action of the information of the clogging is carried out in a step when the lowering of the flow rate is small by learning a relation between the operation accumulating time and the lowering of the flow rate. An apparatus for circulating the bath water acts to remove the clogging of the filter by passing water stream in the reverse direction in a adequate timing.
