Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a bathtub device capable of performing water discharge from a water discharge part immediately after the use start of a pump since comparatively cold residual water from the previous use is supplied to the water discharge part while being mixed with hot bathtub water retained in the bathtub even if there exists such residual water in a flow channel between the pump and the water discharge part, and causing a user to have a sense of cold residual water can be suppressed, thereby improving a degree of freedom on the use of the bathtub device.SOLUTION: A jet pump unit 10 of a bathtub device 1 includes a bathtub communication part 42 which is communicated with a bathtub 2 and into which bathtub water in the bathtub flows, and an injection part 44 arranged on the downstream side of a pump 4 for injecting the bathtub water supplied from the pump so that it passes through the bathtub communication part. The jet pump unit 10 is configured so that the bathtub water injected from the injection part 44 is supplied to a water discharge part 6 while drawing in the bathtub water in the bathtub communication part 42 by a jet pump action.SELECTED DRAWING: Figure 3
【課題】ポンプと吐水部との間の流路内に比較的冷たい前回使用時の残水があったとしても、浴槽に貯留されている温かい浴槽水と混ざりながら吐水部に供給され、使用者に冷たい残水の感覚を感じさせることを抑制することができるため、ポンプの使用開始直後から吐水部からの吐水をすることができ、浴槽装置の使い方の自由度を向上させことができる浴槽装置を提供する。【解決手段】本発明の浴槽装置1のジェットポンプユニット10は、浴槽2と連通され且つ浴槽の浴槽水が流入する浴槽連通部42と、ポンプ4の下流側に配置され且つポンプから供給された浴槽水を浴槽連通部を通るように噴射する噴射部44と、を備え、ジェットポンプユニット10は、この噴射部44から噴射された浴槽水がジェットポンプ作用により浴槽連通部42内の浴槽水を引き込みながら吐水部6に供給されるように構成されていることを特徴とする。【選択図】図3 |
