イッチをフィルタの目詰まり検出用に兼用したことを特
徴とする。For this reason, the present invention provides a water absorption chamber that penetrates through a wall of a bathtub, a filter net that is installed to cover the inlet opening of the water absorption chamber, and a suction port that opens into the water absorption chamber and pumps the water absorption chamber. In a bathtub filter having a water absorption pipe connected to the mouth, the detection pipe of the water level detection pressure switch of the bathtub is installed with the pressure detection port facing the inner wall of the water supply chamber opposite to the opening of the water absorption pipe, When the pump is driven, there is a pressure switch connected to the pressure detection tube.It is equipped with an automatic alarm means that activates an alarm when it detects a set pressure loss, and the pressure switch for detecting the water level in the bathtub is also used for detecting clogging of the filter. It is characterized by having done.
上記の構成によれば、ポンプを運転していないときは、
フイルタを通過する水流が発生せず、従って前記圧力セ
ンサは水位を検出することが出来る。According to the above configuration, when the pump is not operating,
There is no water flow through the filter, so the pressure sensor can detect the water level.
そして、ポンプが作動してフイルタを通過する循環水流
が発生している状態においては、フイルタが目詰まりす
ると、その目詰まりの程度に応じて該フイルタの下流側
の圧力が低下する。If the filter is clogged in the state where the pump is operating and the circulating water flow passing through the filter is generated, the pressure on the downstream side of the filter is reduced according to the degree of the clog.
従って、前記の構成によって圧力センサがある設定圧力
損失を検出したときに警報を発し、この警報によりフイ
ルタが目詰まりしていることを報知し得る。Therefore, with the above configuration, when the pressure sensor detects a certain set pressure loss, an alarm can be issued, and this alarm can notify that the filter is clogged.
前記の構成の如く、検圧管の検圧口が吸水管と反対側の
吸水室内壁に対向していると、ポンプが作動して吸水室
内に湯が流動していても、フイルタが目詰まりしていな
い限り圧力センサは湯の動圧の影響を受けずに水位を検
出して、フイルタが目詰まりするとこれに起因する圧力
損失を検出することが出来る。As described above, if the pressure sensing port of the pressure sensing pipe faces the inner wall of the water absorbing chamber on the side opposite to the water absorbing pipe, the filter will be clogged even if the pump operates and hot water flows in the water absorbing chamber. Unless it is not, the pressure sensor can detect the water level without being affected by the dynamic pressure of the hot water, and can detect the pressure loss due to the clogging of the filter.
