BATH DRAINAGE SYSTEM AND HOT WATER CIRCULATION DETECTION UNIT
To provide a bath drainage system that can appropriately control opening/closing operation of a bathtub drain plug even if a water heater and a drain plug opening/closing device cannot be directly connected by communication.SOLUTION: A bath drainage system A comprises first and second detection means Sa, Sb that can detect a hot water circulation in each of a forward pipe 21 and a return pipe 22 of a bathtub piping part 2 to determine a direction of the hot water circulation, wherein a controller 4 determines whether or not the hot water circulation corresponds to the hot water circulation in a predetermined operation mode in which a drain plug 30 should be opened, based on detection signals from the first and second detection means Sa, Sb when there is the hot water circulation in the bathtub piping part, and the controller controls the drain plug opening/closing device 3 so as to set the drain plug 30 in the open state when the controller determines that it corresponds to the hot water circulation in the predetermined operation mode.SELECTED DRAWING: Figure 1
【課題】給湯器と排水栓用開閉装置とを直接通信接続させ得ない場合であっても、浴槽の排水栓の開閉動作制御を適切に行なうことが可能な風呂排水システムを提供する。【解決手段】風呂排水システムＡは、浴槽配管部２の往き管２１および戻り管２２のそれぞれにおける湯水流通を検出し、かつその湯水流通の方向を判別することが可能な第１および第２の検出手段Ｓａ，Ｓｂを、備えており、コントローラ４は、浴槽配管部に湯水流通があった場合には、この湯水流通が、排水栓３０を開状態とすべき所定の動作モードの湯水流通に該当するか否かを、第１および第２の検出手段Ｓａ，Ｓｂからの検出信号に基づいて判断し、かつ前記所定の動作モードの湯水流通に該当すると判断したときには、排水栓３０を開状態に設定するように排水栓用開閉装置３を制御する。【選択図】 図１
