Description

本発明は、洗浄ノズルを有する局部洗浄装置に関する。 The present invention relates to a local cleaning device having a cleaning nozzle.

従来、洗浄ノズルと、温水源から供給される水を洗浄ノズルに向けて流通させる主流路部と、主流路部から分岐すると共に捨て水を流通させる捨て水流路部と、捨て水流路部を流通される捨て水を一旦受け止めて受け止めた捨て水を便器に排出する排水口が設けられるベースプレートと、を備える局部洗浄装置が知られている（例えば、特許文献１参照）。
特許文献１に記載の局部洗浄装置は、貯湯タンクに過剰に水が供給されないように、貯湯タンクに余分に供給される余剰水を、捨て水として、捨て水流路を流通させて、ベースプレートを介して、便器内に排出する。 Conventionally, a washing nozzle, a main flow passage portion that circulates water supplied from a hot water source toward the washing nozzle, a waste water flow passage portion that branches from the main flow passage portion and disposes discarded water, and a waste water passage portion There is known a local cleaning device including a base plate provided with a drain port for once receiving the discarded water and discharging the received discarded water to the toilet (for example, refer to Patent Document 1).
The local cleaning apparatus described in Patent Document 1 uses excess water to be supplied to the hot water storage tank as excess water so that excess water is supplied to the hot water storage tank as waste water and flows through the waste water flow path to pass through the base plate. And discharge it into the toilet bowl.

特許文献１に記載の局部洗浄装置においては、捨て水流路部を流通する捨て水を、ベースプレートの底部の上面に衝突させて、水の水圧を低減できるように構成される。また、ベースプレートの底部の上面から立ち上がるガイドリブや前面壁を設けることで、捨て水流路部から排出されて本体ケースの底部に衝突した水の前方又は斜め上方への飛散を低減できるように構成される。 The local cleaning device described in Patent Document 1 is configured to collide the waste water flowing through the waste water flow path portion with the upper surface of the bottom portion of the base plate to reduce the water pressure of the water. Further, by providing a guide rib and a front wall rising from the upper surface of the bottom portion of the base plate, it is possible to reduce the splash of water discharged from the waste water flow path portion and colliding with the bottom portion of the main body case forward or obliquely upward. ..

ところで、局部洗浄装置において、温水の供給に関して、ヒータ付きの温水タンクを設けずに、温水がトイレルームの壁に引き回された温水配管から供給される場合がある。このような場合には、温水配管から局部洗浄装置までの距離が長くなりやすく、捨て水の水量も多くなりがちである。捨て水の水量が多い場合には、捨て水の水圧が高くなり、捨て水の勢いが強くなる傾向がある。 Incidentally, in the local cleaning device, there is a case where hot water is supplied from a hot water pipe routed to the wall of the toilet room without providing a hot water tank with a heater. In such a case, the distance from the hot water pipe to the local cleaning device tends to be long, and the amount of waste water tends to increase. When the amount of waste water is large, the water pressure of the waste water increases and the momentum of the waste water tends to increase.

特開平８−９３０３０号公報Japanese Patent Laid-Open No. 8-93030

特許文献１に記載の局部洗浄装置においては、捨て水流路部を流通する捨て水の水圧が高い場合には、ベースプレートの底部に水圧の高い捨て水が衝突するため、ベースプレートの底部から跳ね返る水の勢いが強く、前壁よりも上方まで水が飛散する可能性がある。
また、捨て水流路部を流通する捨て水をベースプレートを介さずに便器内に捨て水を直接排出する局部洗浄装置においては、捨て水流路部を流通する水の水圧が高い場合には、便器のボウル部に水圧の高い水が衝突するため、便器のボウル部から跳ね返る水の勢いが強く、水がおしりに跳ね返ってくることがある。
そのため、捨て水流路部から排出される捨て水の勢いを弱めることができる局部洗浄装置が望まれる。 In the local cleaning apparatus disclosed in Patent Document 1, when the water pressure of the waste water flowing through the waste water flow path portion is high, the bottom water of the base plate collides with the waste water of high water pressure, so that the water splashing from the bottom of the base plate is repelled. The momentum is strong, and water may splash above the front wall.
Further, in the local cleaning device that directly discharges the waste water flowing through the waste water flow path portion into the toilet without passing through the base plate, when the water pressure of the water flowing through the waste water flow path portion is high, Since water with high water pressure collides with the bowl, the force of the water bouncing back from the bowl of the toilet bowl is so strong that the water may bounce off the buttocks.
Therefore, a local cleaning device that can reduce the force of the waste water discharged from the waste water flow path is desired.

First, when the user sits on the toilet seat 2, a detection signal is output from a seat sensor (not shown), and the electromagnetic valve of the waste water valve 43 (see FIG. 2) is opened. As a result, the accumulated water inside the hot water supply pipe 5b of the hot water supply unit 5 reaches the hot water mixing unit 20 and the main valve unit 41.

ここで、メインバルブ部４１内の温度検知部（図示せず）においてメインバルブ部４１の内部の水の水温が適温でないと検知された場合には、捨て水バルブ４３の電磁弁の開状態を維持して、給湯供給部５の給湯配管５ｂに滞留していた水が捨て水としてベースプレート６０を介して便器４に排出される。また、メインバルブ部４１内の温度検知部（図示せず）においてメインバルブ部４１の内部の水の水温が適温であると検知された場合には、捨て水バルブ４３の電磁弁が閉状態となり、捨て水の排出が停止される。 Here, when the temperature detection unit (not shown) in the main valve unit 41 detects that the temperature of the water in the main valve unit 41 is not an appropriate temperature, the open state of the electromagnetic valve of the waste water valve 43 is set. The water retained and retained in the hot water supply pipe 5b of the hot water supply unit 5 is discharged as waste water to the toilet 4 through the base plate 60. When the temperature detection unit (not shown) in the main valve unit 41 detects that the water temperature in the main valve unit 41 is appropriate, the electromagnetic valve of the waste water valve 43 is closed. , The discharge of waste water is stopped.

メインバルブ部４１内の温度検知部（図示せず）においてメインバルブ部４１の内部の水の水温が適温でないと検知された場合において、給湯供給部５の給湯配管５ｂの内部に滞留した滞留水は、捨て水として、メインバルブ部４１から、第１上流側捨て水流路部５２１を介して、捨て水バルブ４３に達し、水圧を有した状態で、図８に示すように、第２上流側流路部５２２から捨て水受け部材５３の流出部５３４に流出される。ここで、捨て水受け部材５３の円筒部５３１における水が流通する方向に直交する方向の断面積Ｓ１は、第２上流側流路部５２２の断面積Ｓ２よりも大きい（図７参照）。そのため、流出部５３４において、捨て水の水圧が大気開放される。これにより、捨て水の水圧を減少させることができる。 When a temperature detection unit (not shown) in the main valve unit 41 detects that the temperature of water in the main valve unit 41 is not an appropriate temperature, accumulated water that has accumulated in the hot water supply pipe 5b of the hot water supply unit 5 As waste water, reaches the waste water valve 43 from the main valve portion 41 via the first upstream waste water flow passage portion 521, and has a water pressure, as shown in FIG. It flows out from the flow path 522 to the outflow part 534 of the waste water receiving member 53. Here, the cross-sectional area S1 of the cylindrical portion 531 of the wastewater receiving member 53 in the direction orthogonal to the direction in which water flows is larger than the cross-sectional area S2 of the second upstream side flow passage portion 522 (see FIG. 7). Therefore, in the outflow part 534, the hydraulic pressure of the waste water is released to the atmosphere. As a result, the water pressure of the waste water can be reduced.

捨て水受け部材５３の流出部５３４において円筒部５３１の内部に流出した捨て水は、図８に示すように、円筒部５３１の内周面において、円筒部５３１の端部壁部５３２側に向かうように、円筒部５３１の内周面に沿って斜め方向に旋回して流れる。ここで。円筒部５３１の内周面に沿って斜め方向に旋回して流れる捨て水は、図８に示すように、円筒部５３１の内部において延在リブ部５３５に衝突し、円筒部５３１の長さ方向への流れに変換されて、端部壁部５３２に向かって流通する。これにより、延在リブ部５３５は、円筒状の円筒部５３１の内周面に沿って旋回して流れる捨て水の勢いを弱めて、円筒部５３１の軸方向に流れるようにガイドできる。これにより、捨て水を、円筒部５３１の径方向に広がることが低減された状態で、端部壁部５３２に向けてガイドできる。 The waste water that has flowed out into the cylindrical portion 531 at the outflow portion 534 of the waste water receiving member 53 heads toward the end wall portion 532 side of the cylindrical portion 531 on the inner peripheral surface of the cylindrical portion 531 as shown in FIG. As described above, the flow swirls obliquely along the inner peripheral surface of the cylindrical portion 531. here. As shown in FIG. 8, the waste water swirling and flowing along the inner peripheral surface of the cylindrical portion 531 collides with the extending rib portion 535 inside the cylindrical portion 531 and the longitudinal direction of the cylindrical portion 531. To the end wall portion 532. As a result, the extending rib portion 535 can guide the waste water that swirls along the inner peripheral surface of the cylindrical portion 531 and flows so as to flow in the axial direction of the cylindrical portion 531. Thereby, the waste water can be guided toward the end wall portion 532 in a state in which the spread of the water in the radial direction of the cylindrical portion 531 is reduced.

そして、捨て水は、端部壁部５３２に衝突する。ここで、端部壁部５３２に衝突した捨て水は、進行方向が反転されて、円筒部５３１の左右方向において、端部壁部５３２とは反対方向の出口開口部５３３に向かって流れる。また、端部壁部５３２に衝突して反転した水は、流出部５３４から流出した水に衝突する。これにより、捨て水を、端部壁部５３２に衝突させると共に、端部壁部５３２に衝突して反転した水を流出部５３４から流出した水に衝突させることで勢いを弱めた状態で、捨て水受け部材５３の出口開口部５３３から排出させることができる。 Then, the discarded water collides with the end wall portion 532. Here, the waste water that has collided with the end wall portion 532 has its traveling direction reversed, and flows toward the outlet opening 533 in the direction opposite to the end wall portion 532 in the left-right direction of the cylindrical portion 531. In addition, the water that has collided with the end wall portion 532 and is reversed collides with the water that has flowed out from the outflow portion 534. This causes the discarded water to collide with the end wall portion 532, and the water that has collided with the end wall portion 532 and reversed to collide with the water that has flowed out from the outflow portion 534. It can be discharged from the outlet opening 533 of the water receiving member 53.

捨て水受け部材５３の出口開口部５３３から排出された捨て水は、ベースプレート６０の上面に排出される。ここで、出口開口部５３３において、捨て水受け部材５３の円筒部５３１の内部から外部に捨て水が排出されることで、捨て水の水圧が大気開放される。これにより、流出部５３４において大気開放されて水圧が低減された捨て水の水圧を、更に、円筒部５３１の出口開口部５３３から排出して大気開放させることができる。これにより、捨て水の水圧を、一層減少させることができる。 The waste water discharged from the outlet opening 533 of the waste water receiving member 53 is discharged to the upper surface of the base plate 60. Here, at the outlet opening 533, the water pressure of the waste water is released to the atmosphere by discharging the waste water from the inside of the cylindrical portion 531 of the waste water receiving member 53 to the outside. As a result, the water pressure of the waste water that has been released to the atmosphere and reduced in water pressure in the outflow portion 534 can be further discharged from the outlet opening 533 of the cylindrical portion 531 and released to the atmosphere. Thereby, the water pressure of the waste water can be further reduced.

ベースプレート６０の上面に排出された捨て水は、第１下段傾斜部６８を左右方向の他方側（図８における右側）から一方側（図８における左側）に向かって流れ、第１排水口６８１から便器４に排出される。
また、第１排水口６８１から排出しきれなかった捨て水は、第１下段傾斜部６８を通り、第２下段傾斜部６９に到達する。そして、捨て水は、第２下段傾斜部６９を前後方向の後方側から前方側に向かって流れ、第２排水口６９１から便器４に排出される。 The waste water discharged to the upper surface of the base plate 60 flows from the other side (the right side in FIG. 8) in the left-right direction to the one side (the left side in FIG. 8) in the first lower sloping portion 68, and from the first drain port 681. It is discharged to the toilet bowl 4.
The waste water that cannot be completely discharged from the first drain port 681 passes through the first lower sloping portion 68 and reaches the second lower sloping portion 69. Then, the discarded water flows through the second lower sloping portion 69 from the rear side in the front-rear direction toward the front side, and is discharged from the second drain port 691 to the toilet bowl 4.

ここで、第２排水口６９１における前方側の縁部には、上方側リブ部６９２が形成される。そのため、捨て水は、ベースプレート６０の前方側において、上方側リブ部６９２にせき止められて、第２排水口６９１から排出される。このため、第２排水口６９１の縁部において、捨て水がベースプレート６０の前方側へ溢れることを低減できる。 Here, an upper rib portion 692 is formed at the front edge of the second drain port 691. Therefore, the discarded water is stopped by the upper rib portion 692 on the front side of the base plate 60 and is discharged from the second drain port 691. Therefore, it is possible to reduce the amount of waste water overflowing to the front side of the base plate 60 at the edge of the second drain port 691.

このようにして、メインバルブ部４１内の水の水温が適温でない場合に、給湯供給部５の給湯配管５ｂの内部に滞留した適温でない滞留水を、捨て水として、便器４に排出することができる。そして、捨て水を便器４に排出する際に、捨て水受け部材５３において、流出部５３４及び出口開口部５３３において捨て水の水圧を大気開放すると共に、端部壁部５３２に捨て水を衝突させ且つ端部壁部５３２に衝突して反転した水を流出部５３４から流出した水に衝突させることで、捨て水の勢いを弱めることができる。このため、捨て水の勢いを弱めた状態で、捨て水を、ベースプレート６０を介して、便器４に排出することができる。
これにより、捨て水の勢いを弱めた状態で、捨て水を、便器４のボウル部４ａ（図６参照）に排出できるため、捨て水が便器４のボウル部４ａから跳ね返ることを低減することができる。 In this way, when the water temperature of the main valve part 41 is not the optimum temperature, the non-optimum temperature accumulated water that has accumulated inside the hot water supply pipe 5b of the hot water supply part 5 can be discharged to the toilet 4 as waste water. it can. When the waste water is discharged to the toilet 4, the waste water receiving member 53 releases the water pressure of the waste water to the atmosphere at the outflow portion 534 and the outlet opening 533, and causes the end wall portion 532 to collide with the waste water. In addition, by colliding the water that has collided with the end wall portion 532 and is reversed with the water that has flown out of the outflow portion 534, the momentum of the discarded water can be weakened. Therefore, the waste water can be discharged to the toilet bowl 4 via the base plate 60 while the force of the waste water is weakened.
Thereby, since the waste water can be discharged to the bowl portion 4a (see FIG. 6) of the toilet bowl 4 in a state in which the force of the waste water is weakened, the splash of the waste water from the bowl portion 4a of the toilet bowl 4 can be reduced. it can.

次に、使用者が、肛門洗浄用ノズル３１又はビデ洗浄用ノズル３２で洗浄を行う場合の局部洗浄装置１０の動作について説明する。
使用者が便座２に着座した状態において、操作ボタン群４６の肛門洗浄用ボタン又はビデ洗浄用ボタンを押すと、ノズル切替バルブ４２の電磁弁が切り替わり、押された肛門洗浄用ボタン又はビデ洗浄用ボタンに対応する肛門洗浄用ノズル３１又はビデ洗浄用ノズル３２への流路が開状態となる。 Next, the operation of the local washing apparatus 10 when the user performs washing with the anus washing nozzle 31 or the bidet washing nozzle 32 will be described.
When the user sits on the toilet seat 2 and presses the anus washing button or bidet washing button of the operation button group 46, the solenoid valve of the nozzle switching valve 42 is switched, and the pushed anus washing button or bidet washing button. The flow path to the anus washing nozzle 31 or the bidet washing nozzle 32 corresponding to the button is opened.

ここで、前述の通り、メインバルブ部４１内の温度検知部（図示せず）において水の水温が適温でないと検知された場合には、給湯供給部５の給湯配管５ｂに滞留していた水が捨て水としてベースプレート６０を介して便器４に排出される。また、メインバルブ部４１内の温度検知部（図示せず）において水の水温が適温であると検知された場合には、捨て水バルブ４３の電磁弁が閉状態となり、捨て水の排出が停止される。 Here, as described above, when the temperature detecting unit (not shown) in the main valve unit 41 detects that the water temperature of the water is not appropriate, the water accumulated in the hot water supply pipe 5b of the hot water supply unit 5 is retained. Is discharged as waste water to the toilet 4 through the base plate 60. When the temperature detection unit (not shown) in the main valve unit 41 detects that the water temperature of the water is appropriate, the electromagnetic valve of the waste water valve 43 is closed and the discharge of the waste water is stopped. To be done.

メインバルブ部４１内の温度検知部（図示せず）において水温が適温であると検知されて捨て水の排出が停止されると、メインバルブ部４１内の温水は、流量調整部４５に送られて、流量が調整される。流量調整部４５において流量が調整された温水は、メインバルブ部４１に戻されて、ノズル切替バルブ４２に流出される。そして、温水は、ノズル切替バルブ４２において切り替えられた流路を介して、肛門洗浄用ノズル３１又はビデ洗浄用ノズル３２に達する。肛門洗浄用ノズル３１又はビデ洗浄用ノズル３２に達した温水は、温水の水圧によりノズルを押し出して、噴出穴（図示せず）から温水を吐出する。このようにして、使用者は、肛門洗浄用ノズル３１又はビデ洗浄用ノズル３２で洗浄を行うことができる。 When the temperature detection unit (not shown) in the main valve unit 41 detects that the water temperature is appropriate and the discharge of the waste water is stopped, the hot water in the main valve unit 41 is sent to the flow rate adjustment unit 45. The flow rate is adjusted. The warm water whose flow rate has been adjusted by the flow rate adjusting unit 45 is returned to the main valve unit 41 and flows out to the nozzle switching valve 42. Then, the hot water reaches the anus washing nozzle 31 or the bidet washing nozzle 32 via the flow path switched by the nozzle switching valve 42. The hot water that has reached the anus washing nozzle 31 or the bidet washing nozzle 32 pushes out the nozzle by the water pressure of the hot water, and discharges the hot water from the ejection hole (not shown). In this way, the user can wash with the anus washing nozzle 31 or the bidet washing nozzle 32.

以上説明した本実施形態の局部洗浄装置１０によれば、以下のような効果を奏する。 The local cleaning device 10 of the present embodiment described above has the following effects.

本実施形態の局部洗浄装置１０は、肛門洗浄用ノズル３１又はビデ洗浄用ノズル３２に向けて供給される水を流通させる主流路部５１と、主流路部５１から分岐すると共に捨て水を流通させる捨て水流路部５２と、を備える局部洗浄装置１０であって、捨て水流路部５２は、第２上流側流路部５２２と、第２上流側流路部５２２を流通した水を流通させると共に水が流通する方向に直交する方向の断面積が第２上流側流路部５２２の断面積よりも大きい捨て水受け部材５３と、を備え、捨て水受け部材５３は、一端側が水を排出する第２排水口６９１側に位置するように配置される円筒部５３１と、円筒部５３１の一端側に設けられる出口開口部５３３と、円筒部５３１の他端側に設けられる端部壁部５３２と、第２上流側流路部５２２を流通する水を端部壁部５３２に向かうように流出させる流出部５３４と、を備える。 The local washing apparatus 10 according to the present embodiment diverges from the main passage portion 51 and the main passage portion 51 that circulates the water supplied toward the anus washing nozzle 31 or the bidet washing nozzle 32, and circulates the discarded water. In the local cleaning device 10 including the waste water flow path portion 52, the waste water flow path portion 52 allows the second upstream flow path portion 522 and the water flowing through the second upstream flow path portion 522 to flow. A drainage water receiving member 53 having a cross-sectional area in a direction orthogonal to a water circulation direction larger than a cross-sectional area of the second upstream-side flow path portion 522; one end side of the wastewater receiving member 53 discharges water. A cylindrical portion 531 arranged to be located on the second drain port 691 side, an outlet opening 533 provided on one end side of the cylindrical portion 531, and an end wall portion 532 provided on the other end side of the cylindrical portion 531. And an outflow portion 534 that allows water flowing through the second upstream-side flow passage portion 522 to flow toward the end wall portion 532.

そのため、捨て水を端部壁部５３２に衝突させて捨て水の進行方向を反転させた後に、捨て水を出口開口部５３３から第２排水口６９１側に排出できる。これにより、捨て水を端部壁部５３２に衝突させることで、捨て水の勢いを弱めることができる。従って、便器４に排出された捨て水が便器４から跳ね返ることを低減できる。 Therefore, the waste water can be discharged from the outlet opening 533 to the second drain port 691 side after the waste water collides with the end wall portion 532 to reverse the traveling direction of the waste water. Thus, by colliding the waste water with the end wall portion 532, the force of the waste water can be weakened. Therefore, it is possible to reduce the splashing of the waste water discharged to the toilet bowl 4 from the toilet bowl 4.

また、流出部５３４は、第２上流側流路部５２２を流通する水を、端部壁部５３２に衝突して反転した水に衝突させるように、端部壁部５３２に向けて流出させる。これにより、端部壁部５３２に捨て水を衝突させ且つ端部壁部５３２に衝突して反転した水を流出部５３４から流出した水に衝突させることで、捨て水の勢いを弱めることができる。 In addition, the outflow portion 534 causes the water flowing through the second upstream flow path portion 522 to flow toward the end wall portion 532 so as to collide with the water that has collided with the end wall portion 532. Thereby, the waste water can be weakened by colliding the waste water with the end wall portion 532, and colliding the water that has collided with the end wall portion 532 and is reversed with the water flowing out from the outflow portion 534. ..

また、捨て水受け部材５３は、水が流通する方向に直交する方向の断面積Ｓ１が第２上流側流路部５２２の断面積Ｓ２よりも大きい。これにより、第２上流側流路部５２２から捨て水受け部材５３に流入される捨て水の水圧は、第２上流側流路部５２２から捨て水受け部材５３に流入する際に、流出部５３４において大気開放される。これにより、捨て水の水圧が低減される。更に、捨て水受け部材５３の出口開口部５３３から排出される捨て水の水圧は、出口開口部５３３から捨て水受け部材５３の外部に排出される際に、出口開口部５３３において大気開放される。
よって、流出部５３４において捨て水の水圧を大気開放すると共に、出口開口部５３３において流出部５３４において大気開放された捨て水の水圧を大気開放することができる。これにより、捨て水の水圧を低減することで、捨て水の勢いを弱めることができる。従って、便器４に排出された捨て水が便器４から跳ね返ることを低減できる。 In addition, in the waste water receiving member 53, the cross-sectional area S1 in the direction orthogonal to the water circulation direction is larger than the cross-sectional area S2 of the second upstream side flow passage portion 522. As a result, the hydraulic pressure of the waste water flowing into the waste water receiving member 53 from the second upstream flow passage portion 522 flows out into the waste water receiving member 53 from the second upstream flow passage portion 522 when it flows out. Is opened to the atmosphere. This reduces the water pressure of the waste water. Further, the water pressure of the waste water discharged from the outlet opening 533 of the waste water receiving member 53 is released to the atmosphere at the outlet opening 533 when being discharged from the outlet opening 533 to the outside of the waste water receiving member 53. ..
Therefore, it is possible to release the water pressure of the waste water to the atmosphere at the outflow portion 534 and release the water pressure of the waste water released to the atmosphere at the outlet opening 533 to the atmosphere. As a result, the pressure of the waste water can be reduced by reducing the water pressure of the waste water. Therefore, it is possible to reduce the splashing of the waste water discharged to the toilet bowl 4 from the toilet bowl 4.

また、本実施形態の局部洗浄装置１０においては、捨て水受け部材５３は、円筒状に形成される円筒部５３１と、円筒部５３１の一端側に形成される出口開口部５３３と、円筒部の他端側に形成される端部壁部５３２と、円筒部５３１の途中の側部を貫通して設けられる流出部５３４と、を有する。そのため、捨て水は、円筒状の円筒部５３１の内周面に沿って流通する。これにより、捨て水受け部材５３に流出した捨て水を、円筒部５３１の内周面に沿って流通させることができるため、例えば、角形状の筒で形成された場合よりも、捨て水の乱流を抑制できる。 Further, in the local cleaning apparatus 10 of the present embodiment, the waste water receiving member 53 has a cylindrical portion 531 formed in a cylindrical shape, an outlet opening 533 formed at one end of the cylindrical portion 531 and a cylindrical portion. It has an end wall portion 532 formed on the other end side and an outflow portion 534 provided to penetrate a side portion in the middle of the cylindrical portion 531. Therefore, the discarded water flows along the inner peripheral surface of the cylindrical cylindrical portion 531. As a result, the waste water that has flowed out to the waste water receiving member 53 can be circulated along the inner peripheral surface of the cylindrical portion 531. Therefore, for example, the waste water is disturbed more than when it is formed of a rectangular tube. The flow can be suppressed.

本実施形態の局部洗浄装置１０においては、円筒部５３１は、円筒部５３１の内部側に突出し且つ円筒部５３１の長さ方向に延びる延在リブ部５３５を備える。そのため、延在リブ部５３５は、円筒状の円筒部５３１の内周面に沿って旋回して流れる捨て水の勢いを弱めて、円筒部５３１の軸方向に流れるようにガイドできる。これにより、捨て水が円筒部５３１の径方向に広がることを低減できる。従って、捨て水が出口開口部５３３から排出される際に、円筒部５３１の径方向に広がることが低減されるため、捨て水の飛散を低減できる。 In the local cleaning apparatus 10 of the present embodiment, the cylindrical portion 531 includes the extending rib portion 535 that projects toward the inside of the cylindrical portion 531 and extends in the longitudinal direction of the cylindrical portion 531. Therefore, the extending rib portion 535 can guide the waste water that swirls along the inner peripheral surface of the cylindrical cylindrical portion 531 and flows so as to flow in the axial direction of the cylindrical portion 531. Thereby, it is possible to reduce the spread of the discarded water in the radial direction of the cylindrical portion 531. Therefore, when the waste water is discharged from the outlet opening 533, it is possible to reduce the spread of the waste water in the radial direction of the cylindrical portion 531 and reduce the scattering of the waste water.

本実施形態の局部洗浄装置１０においては、捨て水受け部材５３は、ベースプレート６０上において、水平に延びるように配置される。これにより、捨て水受け部材５３の円筒部５３１の内部において捨て水の流通方向が反転する本発明において、捨て水が流出部５３４から端部壁部５３２に向かう方向へ流通する場合においても、捨て水が端部壁部５３２から出口開口部５３３に向かう方向へ流通する場合においても、捨て水をスムーズに流通させることができる。 In the local cleaning apparatus 10 of the present embodiment, the waste water receiving member 53 is arranged on the base plate 60 so as to extend horizontally. Thereby, in the present invention in which the circulation direction of the waste water is reversed inside the cylindrical portion 531 of the waste water receiving member 53, even when the waste water flows in the direction from the outflow portion 534 toward the end wall portion 532. Even when the water flows in the direction from the end wall portion 532 toward the outlet opening 533, the discarded water can flow smoothly.

本実施形態の局部洗浄装置１０においては、ベースプレート６０は、第２排水口６９１の縁部に沿って形成され、ベースプレート６０の上面から上方に向けて突出する上方側リブ部６９２を有する。そのため、上方側リブ部６９２は、第２排水口６９１に向かって流れる捨て水は、上方側リブ部６９２にせき止められた状態で、上方側リブ部６９２にガイドされ、第２排水口６９１から排出される。このため、捨て水が第２排水口６９１の縁部において、ベースプレート６０から溢れることを低減できる。 In the local cleaning apparatus 10 of the present embodiment, the base plate 60 has an upper rib portion 692 that is formed along the edge of the second drainage port 691 and projects upward from the upper surface of the base plate 60. Therefore, in the upper rib portion 692, the waste water flowing toward the second drain port 691 is guided by the upper rib portion 692 while being stopped by the upper rib portion 692, and is discharged from the second drain port 691. To be done. Therefore, it is possible to reduce the amount of waste water overflowing from the base plate 60 at the edge of the second drain port 691.

本実施形態の局部洗浄装置１０においては、ベースプレート６０は、便器４の上部に配置されており、ベースプレート６０は、便器４の前後方向における第２排水口６９１と便器４との間においてベースプレート６０の下面から下方に向けて突出する第２下方側リブ部６９３を有する。そのため、便器４の上部にベースプレート６０を配置する際に、第２下方側リブ部６９３を便器４の前方側に配置することで、第２排水口６９１が便器４に乗り上げることを防止できる。また、便器４の上部にベースプレート６０が配置された状態において、第２下方側リブ部６９３により便器４の上面側がガードされるため、第２排水口６９１から排出される水が、便器４の上面とベースプレート６０との間に入り込むことを低減できる。 In the local cleaning device 10 of the present embodiment, the base plate 60 is arranged on the upper part of the toilet bowl 4, and the base plate 60 is disposed between the second drain port 691 and the toilet bowl 4 in the front-back direction of the toilet bowl 4. It has the 2nd lower side rib part 693 which protrudes downward from a lower surface. Therefore, by disposing the second lower rib portion 693 on the front side of the toilet 4 when disposing the base plate 60 on the upper portion of the toilet 4, it is possible to prevent the second drain port 691 from riding on the toilet 4. Further, in the state where the base plate 60 is arranged on the upper portion of the toilet bowl 4, since the upper surface side of the toilet bowl 4 is guarded by the second lower side rib portion 693, the water discharged from the second drain port 691 is discharged onto the upper surface of the toilet bowl 4. It is possible to reduce the penetration between the base plate 60 and the base plate 60.

以上、本発明の局部洗浄装置１０の好ましい一実施形態について説明したが、本発明は、上述した実施形態に制限されるものではなく、適宜変更が可能である。
例えば、前記実施形態では、捨て水受け部材５３を、ベースプレート６０上において、水平に延びるように配置したが、これに限定されない。捨て水受け部材５３を、ベースプレート６０上において、第２排水口６９１側の一端側が下るように傾斜して延びるように配置してもよい。これにより、捨て水受け部材５３の端部壁部５３２に衝突させて反転させた捨て水を、ベースプレート６０の第２排水口６９１側にスムーズに流通させることができる。 The preferred embodiment of the local cleaning apparatus 10 of the present invention has been described above, but the present invention is not limited to the above-described embodiment and can be appropriately modified.
For example, in the above-described embodiment, the wastewater receiving member 53 is arranged so as to extend horizontally on the base plate 60, but the present invention is not limited to this. The waste water receiving member 53 may be arranged on the base plate 60 so as to extend so as to be inclined such that one end side on the second drainage port 691 side is lowered. As a result, the discarded water that has collided with and has been reversed by the end wall portion 532 of the discarded water receiving member 53 can smoothly flow to the second drain port 691 side of the base plate 60.

また、前記実施形態では、捨て水受け部材５３を円筒状に形成したが、これに限定されない。例えば、捨て水受け部材を角筒状に形成してもよいし、捨て水受け部材を上方側が開放した半円筒状に形成してもよい。また、捨て水受け部材は、筒状に限定されない。例えば、捨て水受け部材を、ベースプレート上において仕切板で仕切った流路により構成してもよい。 Further, in the above embodiment, the waste water receiving member 53 is formed in a cylindrical shape, but the present invention is not limited to this. For example, the waste water receiving member may be formed in a rectangular tube shape, or the waste water receiving member may be formed in a semi-cylindrical shape with the upper side open.

For example, the outflow portion 534 of the waste water receiving member 53 may be provided in the outlet opening 533 at one end of the cylindrical portion 531.

また、前記実施形態においては、捨て水流路部５２から排出された水を一旦受け止めるベースプレートを備える構成としたが、これに限定されない。例えば、捨て水受け部材５３（下流側流路部）から排出された水を、ベースプレート６０の第２排水口６９１に直接流れるように構成してもよいし、ベースプレートを備えずに、捨て水受け部材５３に排水管などの排水口を連結することで、捨て水受け部材５３（下流側流路部）から排出された水を、排水管などの排水口に直接流れるように構成してもよい。 Further, in the above-described embodiment, the base plate that temporarily receives the water discharged from the waste water flow path 52 is provided, but the present invention is not limited to this. For example, the water discharged from the waste water receiving member 53 (downstream side flow path portion) may be configured to directly flow to the second drain port 691 of the base plate 60, or the waste water receiving member may be provided without the base plate. By connecting a drain port such as a drain pipe to the member 53, the water discharged from the waste water receiving member 53 (downstream side flow path portion) may be directly flowed to the drain port such as a drain pipe. ..
