Description

上記の目的を達成するために、本発明は、湯水を貯留する浴槽に設けられる浴槽装置であって、上記浴槽内の湯水を吸引し且つこの湯水を下流側のポンプ下流側流路に供給するポンプと、上記ポンプ下流側流路から分岐される第１流路と、上記ポンプ下流側流路から分岐される第２流路と、上記第１流路から供給された湯水を上記浴槽内に吐水する第１吐水部と、上記第２流路から供給された湯水を上記浴槽内に吐水する第２吐水部と、上記ポンプを制御する制御部と、上記第２流路上に設けられるジェットポンプユニットと、を備え、上記第２吐水部の吐水口は、上記第１吐水部の吐水口よりも開口が大きく形成されており、上記ジェットポンプユニットは、ジェットポンプ作用により引き込まれる湯水が貯留されているジェットポンプ水貯留部と、上記ジェットポンプ水貯留部の下流側の上記第２流路の流路径よりも小さな流路径を有し、上記第２流路に供給された湯水を加速させて上記ジェットポンプ水貯留部に噴射する噴射部と、を備え、上記ポンプから供給される湯水を、上記第１吐水部から吐水される湯水の流速が上記第２吐水部から吐水される湯水の流速よりも高くなるように、上記第１吐水部と上記第２吐水部とから同時に吐水させることを特徴としている。
このように構成された本発明においては、ジェットポンプユニットを第２流路上に設けることにより、第１流路から第１吐水部に至る流路の圧力損失と、第２流路から第２吐水部に至る流路の圧力損失と、の差を比較的小さくすることができるので、共通のポンプから供給される湯水が、第１流路及び第２流路のいずれかに大きく偏って供給されることを抑制でき、共通のポンプから供給される湯水を、第１吐水部から吐水される湯水の流速は第２吐水部から吐水される湯水の流速よりも高くなるように、第１吐水部と第２吐水部とから同時に吐水させることができる。
In order to achieve the above object, the present invention is a bathtub device provided in a bathtub for storing hot water, which sucks hot water in the bathtub and supplies the hot water to a downstream pump downstream flow path. A pump, a first channel branched from the pump downstream channel, a second channel branched from the pump downstream channel, and hot water supplied from the first channel into the bathtub A first water discharger that discharges water, a second water discharger that discharges hot water supplied from the second flow path into the bathtub, a control unit that controls the pump, and a jet pump provided on the second flow path A water discharge port of the second water discharge unit is formed to have a larger opening than the water discharge port of the first water discharge unit, and the jet pump unit stores hot water drawn by a jet pump action. Jet pump water And engaging portion has a small channel diameter than the passage diameter of said second flow path downstream of the jet pump water reservoir, to accelerate the jet pump water storage hot water supplied to the second flow path and a jetting unit for jetting the section, the hot water supplied from the pump, so that the hot water flow rate to be discharged from the first water discharge portion is higher than the hot water flow rate to be discharged from the second water portion Further, water is discharged simultaneously from the first water discharger and the second water discharger.
In this invention comprised in this way, by providing a jet pump unit on a 2nd flow path, the pressure loss of the flow path from a 1st flow path to a 1st water discharge part, and a 2nd water discharge from a 2nd flow path Since the difference between the pressure loss of the flow path leading to the section can be made relatively small, the hot water supplied from the common pump is largely biased and supplied to either the first flow path or the second flow path. 1st water discharging part so that the flow rate of hot water discharged from the first water discharging part is higher than the flow rate of hot water discharged from the second water discharging part. And the second water discharger can simultaneously discharge water.
