Zusammenfassung:To provide a bathtub device which prevents hot water from overflowing from a bathtub body as hot water increases in adjusting a temperature of the hot water to be discharged and suppresses unpleasant feeling given to a bathing person because of increased floating feeling the bathing person in the bathtub body experiences.SOLUTION: A bathtub device of the invention includes: a water discharge part 8; a circulation flow passage 4; a first pump 6 for sending hot water taken from a water intake port part in the circulation flow passage; a water supply flow passage 10 for supplying the hot water or water to adjust a temperature of the hot water in the circulation flow passage; a second pump 14 for supplying the hot water in the water supply flow passage; and a control part 16 for controlling the first pump and the second pump. The control part 16 performs the control of the first pump 6 that reduces a flow rate of the hot water flowing in the circulation flow passage so that the flow rate of the hot water flowing in the circulation flow passage 4 is smaller than the flow rate of the hot water or the water supplied from the water supply flow passage 10 in driving the second pump 14 to supply the hot water or water from the water supply flow passage to the circulation flow passage.SELECTED DRAWING: Figure 7 【課題】吐水される湯水の温度調節により湯水が増加して浴槽本体から溢れたり、浴槽本体内の入浴者が感じる浮遊感が増加して入浴者に不快感を与えたりすることを抑制できる浴槽装置を提供することを目的としている。【解決手段】本発明の浴槽装置は、吐水部8と、循環流路4と、取水口部から吸水した湯水を循環流路において送水する第1ポンプ6と、循環流路の湯水の温度を調節するように湯水又は水を供給する給水流路10と、給水流路内の湯水を送水する第2ポンプ14と、第1ポンプ及び第2ポンプを制御する制御部16と、を備え、制御部16は、給水流路から循環流路に湯水又は水を給水するように第2ポンプ14を駆動するときに、給水流路10から供給される湯水又は水の流量よりも、循環流路4を流れる湯水の流量が少なくなるように、循環流路を流れる湯水の流量を低下させる第1ポンプ6の制御を実行する。【選択図】図7
