追い焚き回路の熱交換器側流路を閉成すると共に
熱交換器側流路よりも下流側の流路を開成し、逆
洗用排水回路を閉成し、さらにバイパス回路の逆
洗用排水回路よりも逆洗時における下流側を開成
すると共に逆洗用排水回路よりも逆洗時における
上流側を閉成して熱交換器を通過した逆洗水をバ
イパス回路で逆流させて逆洗用排水回路から排水
させる流路切り換え手段と からなることを特徴とする風呂用濾過装置。[Scope of Claim for Utility Model Registration] A reheating circuit that is equipped with a bath heat exchanger and a pump and is connected to the bathtub, and a filter that is parallel to the flow path in which the bath heat exchanger is installed. a bypass circuit connected to the reheating circuit; a backwash drainage circuit connected to the bypass circuit so as to branch from the upstream side of the filter in the bypass circuit; and, during filtration, the heat exchanger side of the reheating circuit. The flow path is opened and the bypass circuit is closed to allow the filtrate to pass through the bypass circuit in the forward direction, and during backwashing,
Close the heat exchanger side flow path of the reheating circuit, open a flow path downstream of the heat exchanger side flow path, close the backwash drainage circuit, and then close the backwash drainage circuit of the bypass circuit. The downstream side of the circuit is opened during backwashing, and the upstream side of the backwashing drainage circuit is closed during backwashing, and the backwash water that has passed through the heat exchanger is made to flow back through the bypass circuit for backwashing. A bath filtration device comprising a flow path switching means for causing drainage from a drainage circuit.
