Description

ビデ洗浄装置Bidet cleaning equipment
　本発明は、ビデ洗浄装置に関する。 The present invention relates to a bidet cleaning device.
　従来、便器装置に取り付けられ、操作により作動時に伸長して女性身体の局部を洗浄するビデ洗浄装置が知られている。ビデ洗浄装置は、身体を洗浄するための洗浄水を吐水する吐水孔が設けられており、ノズル内を流通した洗浄水が局部に向けて吐水される。局部の周囲も洗浄することができるように、一つの吐水孔から吐水範囲の異なる吐水を行うため、洗浄水を旋回させて、所定範囲に吐水するスポット吐水と、スポット吐水よりも広い範囲に吐水するワイド吐水を行うように構成されたビデ洗浄装置が提案されている（例えば、特許文献１参照）。 2. Description of the Related Art Conventionally, there is known a bidet washing device which is attached to a toilet device and which is extended when operated by operation to wash a local part of a female body. The bidet cleaning device is provided with a water discharging hole for discharging cleaning water for cleaning the body, and the cleaning water flowing through the nozzle is discharged toward a local portion. In order to wash out the area around the local area, water is discharged from a single water discharge hole with a different water discharge range, so that the wash water is swirled to discharge water to a predetermined range and water discharge to a wider area than the spot water discharge. A bidet cleaning device configured to perform wide water discharge is proposed (for example, see Patent Document 1).
　ビデ洗浄装置は、身体を洗浄するための洗浄水を吐水する吐水孔が先端側のヘッド部に設けられており、ノズル内部を流通した洗浄水が局部に向けて吐水される。局部の周囲も洗浄することができるように、局部に向けて吐水する狭モード吐水を行う狭モード吐水孔と、狭モード吐水よりも広い範囲に吐水する広モード吐水を行う広モード吐水孔を有するビデ洗浄装置が提案されている（例えば、特許文献２参照）。この技術では、狭モード吐水孔と広モード吐水孔とが前後に隣接して配置されている。 In the bidet cleaning device, a water discharging hole for discharging cleaning water for cleaning the body is provided in the head portion on the distal end side, and the cleaning water flowing inside the nozzle is discharged toward a local portion. It has a narrow mode water discharge hole that discharges water toward the local area and a wide mode water discharge hole that discharges water in a wider range than the narrow mode water discharge so that the periphery of the local area can be washed. A bidet cleaning device has been proposed (for example, see Patent Document 2). In this technique, a narrow mode water discharge hole and a wide mode water discharge hole are disposed adjacent to each other in front and rear.
　吐水範囲を広げて局部の周囲も洗浄することができるように、一つの吐水孔から、所定範囲に吐水する狭モード吐水と、狭モード吐水よりも広い範囲に吐水する広モード吐水を行うように構成されたビデ洗浄装置が提案されている（例えば、特許文献３参照）。 From one water discharge hole, narrow mode water discharge to discharge water to a predetermined range and wide mode water discharge to discharge water to a wider range than narrow mode water discharge are performed so that the area around the local area can be washed by expanding the water discharge range. A configured bidet cleaning device has been proposed (for example, see Patent Document 3).
特許第５６６９００５号公報Japanese Patent No. 5669005 特許第６０６４２９４号公報Japanese Patent No. 6064294 特許第５６３３８６７号公報Japanese Patent No. 5633867
　特許文献１に記載の技術では、吐水孔から旋回流を利用して円錐状に吐水を行っていた。しかし、一つの吐水孔から旋回流で吐水を行う場合、洗浄範囲の形状が水流によって中央部に中空部を有する中空円錐状に規定される。中空円錐状に吐水すると、着水範囲は略ドーナツ型の範囲になるため、汚れが付着する範囲と必ずしも一致せず、無駄に吐水してしまう場所が発生する場合があった。 技術 In the technology described in Patent Document 1, water is discharged from a water discharge hole in a conical shape using a swirling flow. However, when water is discharged from one water discharge hole by swirling flow, the shape of the cleaning area is defined by the water flow as a hollow cone having a hollow portion at the center. If the water is discharged in a hollow conical shape, the landing area becomes a substantially donut-shaped area, so that the area does not always coincide with the area to which dirt adheres, and a place where water is unnecessarily discharged sometimes occurs.
　図１５は、従来技術を説明する図である。図１５に示すように、ヘッド部１１０に広モード吐水孔８２と狭モード吐水孔８１を前後に並べた場合、後方に位置すると狭モード吐水孔８１から吐水される洗浄水が前方側に傾くように角度をつけて吐水口を配置しなければ、洗浄水が使用者の適切な位置に当たりにくい。しかし、洗浄水を傾けて吐水すると、使用者が着座位置を調整するために座り直したりする際に、洗浄水が便器外へ飛び出す確率が高まってしまうという問題があった。このため、便器外へ洗浄水が飛び出しにくいビデ洗浄装置が望まれていた。 FIG. 15 is a diagram for explaining a conventional technique. As shown in FIG. 15, when the wide mode water discharge holes 82 and the narrow mode water discharge holes 81 are arranged in front and rear on the head unit 110, the cleaning water discharged from the narrow mode water discharge holes 81 is inclined forward when positioned rearward. If the water outlet is not arranged at an angle, the washing water is unlikely to hit the user at an appropriate position. However, if the flush water is inclined and discharged, there is a problem that the probability that the flush water jumps out of the toilet increases when the user sits back to adjust the seating position. For this reason, a bidet washing device in which washing water does not easily flow out of the toilet bowl has been desired.
　狭モードで吐水される範囲は、より汚れが多く付着する局部の周辺に対応する。狭モードで吐水される範囲の着水力が小さいと、最も汚れが多く付着する部分の汚れを十分に落としきれない懸念があった。また、汚れが多く付着する部分では、広モードで吐水している場合でも、効果的に洗浄を行うことが望まれていた。 範 囲 The area where water is discharged in the narrow mode corresponds to the vicinity of a local area where more dirt adheres.

　以上のビデ洗浄装置１は、便器装置７の操作パネル７５等を操作することで、狭モード吐水を行うか、広モード吐水を行うかいずれかが選択され、作動する。
　狭モード吐水を行うように操作された場合は、機能部７４内の制御部により流路切り替え弁が操作され、狭モード流路１３に給水される。狭モード流路１３を流通する洗浄水は、狭モード吐水孔群２１の吐水孔２０ａから使用者の局部に向けて吐水される。
　広モード吐水を行うように操作された場合は、機能部７４内の制御部により流路切り替え弁が操作され、広モード流路１４に給水される。広モード流路１４を流通する洗浄水は、広モード吐水孔群２２の吐水孔２０ｂから使用者の局部の周囲及び局部の前方側及び後方側に向けて吐水される。この時、吐水孔２０ｂから吐水される洗浄水は、使用者に対して略長方形の着水範囲を形成するように吐水される。 The above bidet cleaning device 1 operates by operating the operation panel 75 or the like of the toilet device 7 to select either the narrow mode water discharge or the wide mode water discharge and to operate.
When the operation is performed so as to perform the narrow mode water discharge, the flow path switching valve is operated by the control unit in the function unit 74, and the narrow mode flow path 13 is supplied with water.

The cleaning water flowing through the wide mode flow path 14 is discharged from the water discharge holes 20b of the wide mode water discharge hole group 22 toward the periphery of the user's local area and toward the front and rear of the local area. At this time, the wash water spouted from the spout 20b is spouted so as to form a substantially rectangular landing area for the user.
　本実施形態によれば、以下の効果を奏する。
　本実施形態では、ビデ洗浄装置１を、便器７１後部に対して前後方向に進退可能に設けられ、前後方向を長手方向とする長尺のノズル部１２と、ノズル部１２の先端側に配置され、使用者の身体局部に対して洗浄水を吐水する複数の吐水孔群２と、を含んで構成した。また、複数の吐水孔群２を、所定の範囲に対して吐水する狭モード用の狭モード吐水孔群２１と、所定の範囲よりも広い範囲に吐水する広モード用の広モード吐水孔群２２と、を含んで構成し、広モード吐水孔群２２から吐水される洗浄水が使用者に着水する広モード着水範囲Ｗ１を、前後方向を長手方向とする縦長の形状に形成した。
　複数の吐水孔群２が形成されているので、着水範囲を自在の形状に成形することができ、縦長の形状に吐水することができる。そして、局部を洗浄する狭モード吐水孔群２１と、局部の周囲及び前方側及び後方側を洗浄可能な広モード吐水孔群２２とを有し、広モード着水範囲Ｗ１を縦長形状にすることができるので、中空円錐状に吐水する場合等と比べて汚れが付着する連続した面を隅々まで効率的に洗浄することができる。 According to the present embodiment, the following effects can be obtained.
In the present embodiment, the bidet cleaning device 1 is provided so as to be able to advance and retreat in the front-rear direction with respect to the rear portion of the toilet 71, and is disposed on the tip side of the long nozzle portion 12 having the front-rear direction as a longitudinal direction. And a plurality of water discharge hole groups 2 for discharging cleaning water to the body part of the user. Further, a narrow mode water discharge hole group 21 for discharging a plurality of water discharge hole groups 2 in a predetermined range, and a wide mode water discharge hole group 22 for a wide mode discharge water in a range wider than the predetermined range. The wide mode landing range W1 in which the washing water discharged from the wide mode discharging hole group 22 lands on the user is formed in a vertically long shape having the longitudinal direction in the front-rear direction.
Since the plurality of water discharge hole groups 2 are formed, the water landing area can be formed in any shape, and water can be discharged in a vertically long shape. And it has narrow mode water discharge hole group 21 which wash | cleans a local part, and wide mode water discharge hole group 22 which can wash | clean the circumference, a front side, and the back side of a local part, and makes wide mode water landing range W1 a vertical shape. Therefore, a continuous surface to which dirt adheres can be efficiently cleaned to every corner as compared with a case where water is discharged in a hollow conical shape.
　本実施形態では、縦長の形状を、略長方形状とした。広モード着水範囲Ｗ１を長方形にすることで、局部の周囲の所定幅を有するとともに前後方向に長い汚れが付着しやすい範囲を全面的に洗浄することができ、洗浄効率が高まる。 In the present embodiment, the vertically long shape is a substantially rectangular shape. By making the wide mode water landing range W1 rectangular, it is possible to completely clean the area having a predetermined width around the local area and to which long dirt is likely to adhere in the front-rear direction, thereby increasing the cleaning efficiency.
　本実施形態では、広モード着水範囲Ｗ１の中心Ｃ２を、狭モード吐水孔群２１から吐水される洗浄水が使用者に着水する狭モード着水範囲Ｎ１の中心Ｃ１よりも、後方に位置させた。
　使用者の局部から後方は、使用者が就寝時に横たわることで、経血が広がって付着しやすい。広モード着水範囲Ｗ１の中心Ｃ２が狭モード着水範囲Ｎ１の中心Ｃ１よりも後方に位置することにより、局部より後方に多く吐水され、広がった汚れをより効率的に洗浄することができる。 In the present embodiment, the center C2 of the wide-mode water landing range W1 is located behind the center C1 of the narrow-mode water landing range N1 where the washing water discharged from the narrow-mode water discharging hole group 21 lands on the user. I let it.
From the local part of the user, menstrual blood spreads and easily adheres when the user lays down at bedtime. Since the center C2 of the wide-mode water landing range W1 is located behind the center C1 of the narrow-mode water landing range N1, a large amount of water is discharged behind the local area, and the spread dirt can be more efficiently washed.
　本実施形態では、複数の吐水孔群２における各吐水孔２０の少なくとも一部を、互いに異なる角度で洗浄水を吐水するように構成した。吐水孔２０それぞれの角度を互いに異なるように変えることにより、ヘッド部１１が小型であっても、広い範囲に吐水をすることが可能になる。また、着水範囲の成形が容易になる。 In the present embodiment, at least a part of each of the water discharge holes 20 in the plurality of water discharge hole groups 2 is configured to discharge the wash water at different angles. By changing the angles of the water discharge holes 20 to be different from each other, it is possible to discharge water over a wide range even if the head portion 11 is small. In addition, the formation of the water landing area is facilitated.
　以上、本発明の好ましい実施形態について説明したが、本発明は、上述の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。 Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be appropriately modified.
　図７は、第２実施形態に係るビデ洗浄装置の着水範囲を示す模式図である。Ｆは前方、Ｒは後方を示す。第２実施形態以降の説明において、第１実施形態と共通する部分については説明を省略する。図７中、太い線の円で示すように、第２実施形態では、広モード着水範囲Ｗ１のうち、広モード着水範囲Ｗ１の中心Ｃ２よりも前方側に、高い着水力で洗浄水が吐水される。 FIG. 7 is a schematic diagram illustrating a landing area of the bidet cleaning device according to the second embodiment. F indicates the front and R indicates the rear. In the description of the second and subsequent embodiments, description of parts common to the first embodiment will be omitted. In the second embodiment, as shown by the bold line circle in FIG. 7, in the wide mode landing range W1, the cleaning water with a high landing power is located forward of the center C2 of the wide mode landing range W1. It is spouted.
　着水力とは、洗浄水が使用者に着水するときの着水流速、着水水量、着水圧力の少なくともいずれかを意味する。また、着水力とは、単位面積あたりの洗浄水が有する運動量であり、汚れを落とす力を言う。また、着水流速、着水水量、着水圧力とは、吐水孔２０から吐水されて使用者に着水した地点、又は吐水孔２０から使用者が位置すると想定する位置まで離れた地点での流速、水量、圧力を言う。洗浄水の着水流速や、着水水量、着水圧力等を変更することにより、着水力を強くしたり弱くしたりすることができる。
　例えば、広モードの着水範囲の中心よりも前方側で洗浄水の着水流速が早いとき、又は前方側に吐水される洗浄水の着水流量が多いとき、又は前方側に吐水される洗浄水の着水圧力が高いとき、付着した汚れは剥離して流されやすくなり、洗浄力が高まる。 The landing power means at least one of a landing velocity, an amount of landing water, and a landing pressure when the washing water lands on the user. In addition, the water landing power is the momentum of the cleaning water per unit area, and refers to a power for removing dirt. In addition, the landing velocity, the landing water amount, and the landing pressure are defined as a point at which the water is discharged from the water discharge hole 20 and lands on the user, or a point at which the user is supposed to be located from the water discharge hole 20. Flow rate, water volume, pressure. The landing power can be increased or decreased by changing the landing velocity, the amount of landing water, the landing pressure, etc. of the washing water.
For example, when the landing speed of the washing water is higher on the front side than the center of the landing range in the wide mode, or when the landing flow rate of the washing water discharged on the front side is large, or the washing is discharged on the front side. When the pressure at which water is applied is high, the adhered dirt is easily separated and washed away, and the cleaning power is increased.
　例えば、着水力の高低は、広モード吐水孔群２２の口径を変更することで異なるように構成することができる。広モードの着水範囲の中心よりも前方側に位置する広モード吐水孔群２２の前方側の吐水孔２０を、後方側の吐水孔よりも小さくすることで、広モード吐水孔群２２の前方側から吐水される洗浄水の着水力を高くすることができる。 For example, the level of the water landing force can be configured to be different by changing the diameter of the wide mode water discharge hole group 22. The water discharge hole 20 on the front side of the wide mode water discharge hole group 22 located on the front side of the center of the water landing range of the wide mode is smaller than the water discharge hole on the rear side, so that the front of the wide mode water discharge hole group 22 is formed. The landing power of the wash water spouted from the side can be increased.
　また、変形例として、広モード吐水孔群２２の口径は変えずに、数を変更し、前方側と後方側における単位面積当たりの開口面積を変更することで、広モードの着水範囲内における着水力を変更することができる。すなわち、前方側に位置する広モード吐水孔群２２の数を減らし、後方側に位置する広モード吐水孔群２２の数を多くすることで、広モード吐水孔群２２の前方側から吐水される洗浄水の着水力を高くすることができる。 Also, as a modification, the diameter of the wide mode water discharge hole group 22 is not changed, the number is changed, and the opening area per unit area on the front side and the rear side is changed, so that the water discharge range in the wide mode water discharge hole group is changed. The landing power can be changed. That is, by reducing the number of the wide mode water discharge holes 22 located on the front side and increasing the number of the wide mode water discharge holes 22 located on the rear side, water is discharged from the front side of the wide mode water discharge holes 22. The landing power of the washing water can be increased.
　また、変形例として、広モード吐水孔群２２の配置を変えずに、広モード吐水孔群２２の吐水孔２０の向きを変更することで、広モードの着水範囲内における着水力を変更することができる。例えば、前後方向に長い広モードの着水範囲のうち中心付近に配置される吐水孔２０の向きを、前方側に向けて傾けることで、広モード吐水孔群２２の前方側から吐水される洗浄水の着水力を高くすることができる。 Further, as a modified example, by changing the direction of the water discharge holes 20 of the wide mode water discharge hole group 22 without changing the arrangement of the wide mode water discharge hole group 22, the water landing force within the water discharge range of the wide mode is changed. be able to. For example, the water discharged from the front side of the wide-mode water discharge hole group 22 is inclined by inclining the direction of the water discharge holes 20 arranged near the center of the wide-mode water landing range long in the front-rear direction toward the front side. The water landing power can be increased.
　さらに他の変形例として、広モード流路１４を前方側へ供給する流路と後方側に供給する流路を分け、広モード流路１４に洗浄水を供給するポンプを制御することで、前方側及び後方側に流れる洗浄水の流速、水量、圧力の少なくともいずれかを変化させることができる。 As still another modified example, the flow path for supplying the wide mode flow path 14 to the front side and the flow path for supplying the rear side are separated, and the pump for supplying the cleaning water to the wide mode flow path 14 is controlled. It is possible to change at least one of the flow rate, the amount of water, and the pressure of the washing water flowing on the side and the rear side.
　第２実施形態によれば、局部から前方側に付着した汚れを洗浄しやすくできる。使用者が横たわる等の特別な姿勢を取らない場合、起立したり歩行したりすることで、経血等の汚れは局部から前方側に広がりやすい。このような場合、局部から前方側で着水力を高めることで、汚れの付着しやすい局部の前方側を効率的に洗浄することができる。 According to the second embodiment, it is possible to easily clean dirt attached from the local area to the front side. When the user does not take a special posture such as lying down, standing up or walking tends to spread dirt such as menstrual blood from a local area to the front side. In such a case, by increasing the water landing force on the front side from the local part, the front side of the local part where dirt is likely to adhere can be efficiently cleaned.
　図８は、第３実施形態に係るビデ洗浄装置の着水範囲を示す模式図である。Ｆは前方、Ｒは後方を示す。第３実施形態の説明において、着水力の定義及び着水力を変更する手段については、第２実施形態と共通する。 FIG. 8 is a schematic diagram illustrating a landing area of the bidet cleaning device according to the third embodiment. F indicates the front and R indicates the rear. In the description of the third embodiment, the definition of the landing power and means for changing the landing power are the same as those of the second embodiment.
　図８中、太い線の円で示すように、第３実施形態では、長方形の広モード着水範囲Ｗ１のうち、狭モード着水範囲Ｎ１と少なくとも一部が重なる範囲内で、狭モード着水範囲Ｎ１と重ならない範囲よりも高い着水力で洗浄水が吐水される高着水力洗浄範囲Ｗ２が形成される。そして、高着水力洗浄範囲Ｗ２の着水中心は、狭モード着水範囲Ｎ１内に分布するように配置される。高着水力洗浄範囲Ｗ２の着水中心とは、高着水力洗浄範囲Ｗ２の中で着水力が最も高くなる位置であり、図８に示すＷ２の範囲の図形上の中心ではない。高着水力洗浄範囲Ｗ２の着水中心は、孔の向きや口径等を変更することによって、狭モード着水範囲Ｎ１内に配置されるように調整される。 In the third embodiment, as shown by the bold line circle in FIG. 8, the narrow mode landing area N1 is at least partially overlapped with the narrow mode landing area N1 in the rectangular wide mode landing area W1. A high-watering-power cleaning range W2 in which the cleaning water is discharged with a higher watering power than a range that does not overlap the range N1 is formed. The landing center of the high-water-strength washing range W2 is arranged so as to be distributed within the narrow-mode landing range N1. The landing center of the high-water-strength cleaning range W2 is the position where the water-stripping force is highest in the high-water-strength cleaning range W2, and is not the center of the figure in the range of W2 shown in FIG. The landing center of the high landing power washing range W2 is adjusted so as to be located in the narrow mode landing range N1 by changing the direction and diameter of the hole.
　狭モード吐水孔群２１の狭モード着水範囲Ｎ１は、局部が位置すると想定される位置を含んだ位置にある。広モードにおける高着水力洗浄範囲Ｗ２の着水中心が、狭モード着水範囲Ｎ１内にあることで、広モード吐水を行っている時にも、局部が位置すると想定される位置を含んだ部分に高い着水力で着水される。このため、広モード着水範囲Ｗ１を洗浄しながら、局部の周囲の高着水力洗浄範囲Ｗ２において、汚れの付着しやすい部分を効率的に洗浄することができる。 狭 The narrow mode landing range N1 of the narrow mode water discharge hole group 21 is at a position including a position where a local part is assumed to be located. Since the landing center of the high water-strength cleaning range W2 in the wide mode is within the narrow-mode water-falling range N1, even when performing wide-mode water discharge, the area including the position where the local part is assumed to be located is included. Landed with high water landing power. For this reason, while the wide mode water landing range W1 is being cleaned, a portion to which dirt easily adheres can be efficiently cleaned in the high water landing power cleaning range W2 around the local area.
　次に、第４実施形態に係るビデ洗浄装置１Ａについて説明する。図９は、ヘッド部１１Ａの上面を示し、図９（ａ）は、狭モード吐水孔群２１を示し、図９（ｂ）は広モード吐水孔群２２を示す。 Next, a bidet cleaning device 1A according to a fourth embodiment will be described. 9A and 9B show the upper surface of the head 11A. FIG. 9A shows a narrow mode water discharge hole group 21 and FIG. 9B shows a wide mode water discharge hole group 22.
　広モード吐水孔群２２は、ヘッド部１１Ａの前後方向に沿う縦長の領域内に、長手方向が前後方向に沿うように配置されている。図９（ｂ）に示すように、複数の広モード吐水孔群２２を構成する吐水孔２０ｂの最前端に位置する吐水孔２０ｂと、最後端に位置する吐水孔２０ｂと、前後方向に直交する幅方向の最外側に位置する吐水孔２０ｂのそれぞれの外側に接する接線で囲んだ連続した領域を、広モード吐水孔群配置領域Ｐとする。広モード吐水孔群２２は、広モード吐水孔群配置領域Ｐにおいて必ずしも全体に配置されておらず、広モード吐水孔群２２が配置されていない箇所があってもよいが、吐水孔２０ｂを傾ける等することで、前後範囲が一定した所定の範囲に洗浄水を吐水可能に構成されている。 The wide mode water discharge hole group 22 is disposed in a vertically long region along the front-rear direction of the head portion 11A so that the longitudinal direction is along the front-rear direction. As shown in FIG. 9B, the water discharge hole 20b located at the foremost end of the water discharge holes 20b constituting the plurality of wide mode water discharge hole groups 22 and the water discharge hole 20b located at the rearmost end are orthogonal to the front-rear direction. A continuous area surrounded by a tangent line in contact with each of the outermost water discharge holes 20b in the width direction is defined as a wide mode water discharge hole group arrangement area P. The wide mode water discharge hole group 22 is not necessarily arranged in the whole in the wide mode water discharge hole group arrangement area P, and there may be a place where the wide mode water discharge hole group 22 is not disposed, but the water discharge hole 20b is inclined. By doing so, the washing water can be discharged into a predetermined range where the front and rear ranges are constant.
　図９（ｂ）に示すように、広モード吐水孔群配置領域Ｐの前後方向における一方の端部と他方の端部との間の範囲内に、狭モード吐水孔群２１が配置されている。すなわち、広モード吐水孔群配置領域Ｐの前端の吐水孔２０ｂから幅方向に延出する第１仮想線Ｌ１と、前記広モード吐水孔群配置領域Ｐの後端の吐水孔２０ｂから幅方向に延出する第２仮想線Ｌ２と、の間の前後方向に連続する範囲内に、狭モード吐水孔群２１が配置されている。 As shown in FIG. 9B, a narrow mode water discharge hole group 21 is arranged in a range between one end and the other end in the front-rear direction of the wide mode water discharge hole group arrangement region P. . That is, the first virtual line L1 extending in the width direction from the water discharge hole 20b at the front end of the wide mode water discharge hole group arrangement area P, and the width direction from the water discharge hole 20b at the rear end of the wide mode water discharge hole group arrangement area P The narrow mode water discharge hole group 21 is arranged in a range continuous with the extending second virtual line L2 in the front-back direction.
　図１０は、狭モード吐水孔群２１から吐水される洗浄水と、広モード吐水孔群２２から吐水される洗浄水のそれぞれの吐水範囲を、ヘッド部１１Ａの側面から見た模式図である。図９（ａ）～図１０に示すように、狭モード吐水孔群２１は、ヘッド部１１Ａの側面視において、広モード吐水孔群２２に重なるように配置されている。この配置により、狭モード吐水孔群２１と広モード吐水孔群２２とをヘッド部１１Ａの前後方向に配置した場合と比べて、広モード吐水孔群２２から吐水する洗浄水の角度θ２及び狭モード吐水孔群２１から吐水する洗浄水の角度θ１を大きくすることができる。 FIG. 10 is a schematic view showing the respective water discharge ranges of the wash water discharged from the narrow mode water discharge hole group 21 and the wash water discharged from the wide mode water discharge hole group 22 as viewed from the side surface of the head 11A. As shown in FIGS. 9A to 10, the narrow mode water discharge hole group 21 is disposed so as to overlap the wide mode water discharge hole group 22 in a side view of the head 11A. With this arrangement, the angle θ2 of the wash water spouted from the wide mode water discharge hole group 22 and the narrow mode water discharge hole group 21 and the narrow mode water discharge hole group 21 and the wide mode water discharge hole group 22 are arranged in the front-back direction of the head 11A. The angle θ1 of the wash water spouted from the spout group 21 can be increased.
　吐水角度とは、便器装置７の設置面と平行な仮想水平線Ｈをヘッド部１１Ａの前端部の中心Ｃを通って延出させ、この仮想水平線Ｈと、狭モード吐水孔群２１の前側から吐水される洗浄水の吐水方向又は広モード吐水孔群２２の前側から吐水される洗浄水の吐水方向との間に形成される角度である。吐水角度が小さいと、便器外へ洗浄水が飛び出す確率が大きくなるが、吐水角度が大きいと、洗浄水は上方へ向かい、使用者に当たって便器外へ飛び出す確率は小さくなる。 The water discharge angle is such that a virtual horizontal line H parallel to the installation surface of the toilet device 7 extends through the center C of the front end of the head 11A, and water is discharged from the virtual horizontal line H and the front side of the narrow mode water discharge hole group 21. This is an angle formed between the direction in which the wash water is discharged or the direction in which the wash water is discharged from the front side of the wide mode water discharge hole group 22. When the water discharge angle is small, the probability that the flush water jumps out of the toilet is increased. However, when the water discharge angle is large, the wash water is directed upward and the probability that the flush water hits the user and falls out of the toilet is reduced.
　図９（ａ）及び図１０に示すように、狭モード吐水孔群２１が４つの吐水孔２０ａで構成され、広モード吐水孔群配置領域Ｐ内で所定の広がりをもって配置されることによっても、吐水角度は大きくなる。 As shown in FIGS. 9A and 10, the narrow mode water discharge hole group 21 is configured by four water discharge holes 20 a and arranged with a predetermined spread in the wide mode water discharge hole group arrangement region P. The spout angle increases.
　図１１（ａ）は、狭モード吐水孔群の流路を示し、図１１（ｂ）は広モード吐水孔群の流路を示す。
　ノズル部１２及びヘッド部１１Ａの内部には、給水源と連絡する洗浄水の流路が形成されている。ノズル部１２及びヘッド部１１Ａは、狭モード吐水孔群２１に連通する狭モード流路１３と、広モード吐水孔群２２に連通する広モード流路１４とを有する。 FIG. 11A shows a flow path of a narrow mode water discharge hole group, and FIG. 11B shows a flow path of a wide mode water discharge hole group.
Inside the nozzle section 12 and the head section 11A, a flow path of washing water communicating with a water supply source is formed. The nozzle section 12 and the head section 11A have a narrow mode flow path 13 communicating with the narrow mode water discharge hole group 21 and a wide mode flow path 14 communicating with the wide mode water discharge hole group 22.
　狭モード流路１３及び広モード流路１４は、具体的には同軸で二重の給水管により形成されており、中心側が狭モード流路１３となり、狭モード流路１３から隔壁を隔てた外側が広モード流路１４となっている。ノズル部１２の基端には、狭モード流路１３及び広モード流路１４それぞれに給水する２本の給水管が接続されている。 The narrow mode flow path 13 and the wide mode flow path 14 are specifically formed by a coaxial double water supply pipe, and the center side is the narrow mode flow path 13, and the outer side is separated from the narrow mode flow path 13 by a partition wall. Are the wide mode flow paths 14. Two water supply pipes for supplying water to the narrow mode flow path 13 and the wide mode flow path 14 are connected to the base end of the nozzle portion 12.
　以上のビデ洗浄装置１は、便器装置７の操作パネル７５等を操作することで、狭モード吐水を行うか、広モード吐水を行うかいずれかが選択され、作動する。
　狭モード吐水を行うように操作された場合は、機能部７４内の制御部により流路切り替え弁が操作され、狭モード流路１３に給水される。狭モード流路１３を流通する洗浄水は、狭モード吐水孔群２１の吐水孔２０ａから使用者の局部に向けて吐水される。
　広モード吐水を行うように操作された場合は、機能部７４内の制御部により流路切り替え弁が操作され、広モード流路１４に給水される。広モード流路１４を流通する洗浄水は、広モード吐水孔群２２の吐水孔２０ｂから使用者の局部の周囲及び局部の前方側及び後方側に向けて吐水される。 The above bidet cleaning device 1 operates by operating the operation panel 75 or the like of the toilet device 7 to select either the narrow mode water discharge or the wide mode water discharge and to operate.
When the operation is performed so as to perform the narrow mode water discharge, the flow path switching valve is operated by the control unit in the function unit 74, and the narrow mode flow path 13 is supplied with water. The wash water flowing through the narrow mode flow path 13 is discharged from the water discharge holes 20a of the narrow mode water discharge hole group 21 toward the local part of the user.
When the operation is performed to perform the wide mode water discharge, the flow path switching valve is operated by the control unit in the function unit 74, and water is supplied to the wide mode flow path 14. The cleaning water flowing through the wide mode flow path 14 is discharged from the water discharge holes 20b of the wide mode water discharge hole group 22 toward the periphery of the user's local area and toward the front and rear of the local area.
　第４実施形態によれば、以下の効果を奏する。
　第４本実施形態では、ビデ洗浄装置１Ａを、便器７１後部に対して前後方向に進退可能に設けられ、前後方向を長手方向とする長尺のノズル部１２と、ノズル部１２の先端側に配置され、使用者の身体局部に対して洗浄水を吐水する複数の吐水孔群２が設けられるヘッド部１１Ａと、を含んで構成した。また、複数の吐水孔群２を、身体局部近傍の所定の範囲に対して吐水する狭モード吐水用の狭モード吐水孔群２１と、所定の範囲よりも広い範囲に吐水する広モード吐水用の広モード吐水孔群２２と、を含んで構成し、広モード吐水孔群２２の周囲を囲む広モード吐水孔群配置領域Ｐを形成した。また、ヘッド部１１Ａにおける広モード吐水孔群配置領域Ｐの前端の吐水孔２０ｂから幅方向に延出する第１仮想線Ｌ１と、広モード吐水孔群配置領域Ｐの後端の吐水孔２０ｂから幅方向に延出する第２仮想線Ｌ２と、の間の前後方向に連続する範囲内に、狭モード吐水孔群２１を配置した。
　狭モード吐水孔群２１を、広モード吐水孔群配置領域Ｐの前端から幅方向に延出する第１仮想線Ｌ１と、後端から幅方向に延出する第２仮想線Ｌ２と、の間の前後方向に連続する範囲内に配置することにより、狭モード吐水孔群２１を広モード吐水孔群配置領域Ｐの後方から前方に向けて吐水する場合と比べて、吐水角度が大きくなり、使用者に向けて上方に吐水することが可能になる。よって、狭モード吐水孔群２１から吐水する場合に、洗浄水が便器７１の外へ飛び散ることを防止することができる。 According to the fourth embodiment, the following effects can be obtained.
In the fourth embodiment, the bidet cleaning device 1A is provided so as to be able to advance and retreat in the front-rear direction with respect to the rear portion of the toilet 71, and has a long nozzle portion 12 whose longitudinal direction is the front-rear direction. And a head portion 11A provided with a plurality of water discharge hole groups 2 for discharging the wash water to the body part of the user. In addition, a plurality of water discharge hole groups 2, a narrow mode water discharge hole group 21 for discharging water in a predetermined range near the body part, and a wide mode water discharge hole for discharging water in a wider range than the predetermined range. The wide mode water discharge hole group 22 is formed, and the wide mode water discharge hole group arrangement region P surrounding the wide mode water discharge hole group 22 is formed. Also, the first virtual line L1 extending in the width direction from the water discharge hole 20b at the front end of the wide mode water discharge hole group arrangement area P in the head portion 11A and the water discharge hole 20b at the rear end of the wide mode water discharge hole group arrangement area P The narrow mode water discharge hole group 21 is arranged in a range continuous in the front-rear direction between the second virtual line L2 extending in the width direction.

As shown in FIG. 12, in the fifth embodiment, the center position C1 of the narrow mode water discharge hole group 21 is disposed on the front side with respect to the center position C2 of the wide mode water discharge hole group arrangement area P. Since the narrow mode water discharge hole group 21 is shifted toward the front side of the head portion 11B, the water discharge direction does not need to be inclined forward, so that the angle θ1 of the wash water discharged from the narrow mode water discharge hole group 21 can be easily increased.

The narrow mode water discharge hole group 21C and the wide mode water discharge hole group 22C are arranged so as to overlap in the side view of the head 11C. Also according to the arrangement of the sixth embodiment, as compared with the case where the narrow mode water discharge hole group 21 discharges water from the rear to the front of the wide mode water discharge hole group arrangement region P, the water discharge angle increases, and the water discharge angle increases toward the user. Therefore, the same effect as in the fourth embodiment can be obtained.

The flow velocity discharged from the core 220a is higher than the flow velocity discharged from the peripheral part 220b.
　図１８は、広モード吐水時における着水力と、広モード着水範囲Ｗ１における前後方向の着水位置の関係を示す図である。本明細書において、着水力とは、吐水孔２０から吐水される水の質量と速度との積で求められる値である。図中の横軸は、広モード着水範囲Ｗ１における前後方向の着水位置を示し、縦軸は、着水力を示している。図１８に示すように、広モード着水範囲Ｗ１における前後方向の中央部付近では、着水力は中央付近以外の部分よりも高くなっている。広モード着水範囲Ｗ１の前後方向の中央部付近は、コア部２２０ａから吐水される洗浄水が着水するコア着水部２２１が位置しており、コア着水部２２１における着水力は、周辺部２２０ｂから吐水される洗浄水が着水する周辺着水部２２２における着水力よりも高い。 FIG. 18 is a diagram showing the relationship between the water landing force at the time of wide mode water discharge and the water landing position in the front-rear direction in the wide mode water landing range W1. In the present specification, the water landing force is a value obtained by multiplying the mass of water discharged from the water discharge hole 20 by the velocity. The horizontal axis in the figure indicates the landing position in the front-rear direction in the wide mode landing range W1, and the vertical axis indicates the landing power. As shown in FIG. 18, the water landing force is higher near the center in the front-rear direction in the wide mode water landing range W1 than at portions other than the vicinity of the center. In the vicinity of the center in the front-rear direction of the wide mode landing range W1, a core landing section 221 on which the wash water discharged from the core section 220a lands is located. The washing water discharged from the section 220b is higher than the water landing force in the peripheral water landing section 222 where water is landed.
　図１９（ａ）は、狭モード吐水群の流路を示し、図１９（ｂ）は広モード吐水群の流路を示す。
　ノズル部１２及びヘッド部１１Ｅの内部には、給水源と連絡する洗浄水の流路が形成されている。ノズル部１２及びヘッド部１１Ｅは、狭域吐水孔群２１０に連通する狭モード流路１３と、広域吐水孔群２２０に連通する広モード流路１４とを有する。 FIG. 19A shows the flow path of the narrow mode water discharge group, and FIG. 19B shows the flow path of the wide mode water discharge group.
Inside the nozzle section 12 and the head section 11E, a flow path of cleaning water communicating with a water supply source is formed. The nozzle section 12 and the head section 11E have a narrow mode flow path 13 communicating with the narrow area water discharge hole group 210 and a wide mode flow path 14 communicating with the wide area water discharge hole group 220.
　狭モード流路１３及び広モード流路１４は、具体的には同軸で二重の給水管により形成されており、中心側が狭モード流路１３となり、狭モード流路１３から隔壁を隔てた外側が広モード流路１４となっている。ノズル部１２の基端には、狭モード流路１３及び広モード流路１４それぞれに給水する２本の給水管が接続されている。 The narrow mode flow path 13 and the wide mode flow path 14 are specifically formed by a coaxial double water supply pipe, and the center side is the narrow mode flow path 13, and the outer side is separated from the narrow mode flow path 13 by a partition wall. Are the wide mode flow paths 14. Two water supply pipes for supplying water to the narrow mode flow path 13 and the wide mode flow path 14 are connected to the base end of the nozzle portion 12.
　図２０は、洗浄水が着水した位置における狭モード吐水の着水力と、広モード吐水の着水力との関係を示す図である。図中の横軸は、広モード着水範囲Ｗ１及び狭モード着水範囲Ｎ１における前後方向の着水位置を示し、縦軸は、着水力を示し、図中、狭モード吐水をＮで示し、広モード吐水をＷで示している。 FIG. 20 is a diagram showing the relationship between the water landing force of the narrow mode water discharge and the water discharge force of the wide mode water discharge at the position where the cleaning water has landed. The horizontal axis in the drawing indicates the water landing position in the front-rear direction in the wide mode landing range W1 and the narrow mode landing range N1, the vertical axis indicates the landing power, and the narrow mode water discharge is indicated by N in the figure. Wide mode water discharge is indicated by W.
　狭モード流路１３及び広モード流路１４は、互いに流路が異なっているため、狭域吐水孔群２１０と広域吐水孔群２２０との口径差（開口面積の差）のみが着水力に影響すると考えることはできないが、狭モード吐水における着水力と、広モード吐水における着水力を比較すると、狭モード吐水における着水力が、広モード吐水の際に広域吐水孔群２２０における周辺部２２０ｂから吐水された洗浄水の着水力（周辺着水部２２２の着水力）よりも高くなるように流速が調整されている。また、狭モード吐水における着水力は、広モード吐水の際にコア部２２０ａから吐水された洗浄水の着水力（コア着水部２２１の着水力）よりも高くなるように流速が調整されている。 Since the narrow mode flow path 13 and the wide mode flow path 14 are different from each other, only the diameter difference (difference in opening area) between the narrow area water discharge hole group 210 and the wide area water discharge hole group 220 affects the water landing force. Although it cannot be considered, when comparing the water landing force in the narrow mode water discharge with the water landing force in the wide mode water discharge, the water landing force in the narrow mode water discharge is discharged from the peripheral portion 220b in the wide area water discharge hole group 220 at the time of the wide mode water discharge. The flow velocity is adjusted so as to be higher than the landing power of the cleaning water (the landing power of the peripheral landing section 222). Further, the flow velocity is adjusted so that the water landing force in the narrow mode water discharge is higher than the water landing force (water landing force of the core water landing part 221) of the wash water discharged from the core part 220a at the time of the wide mode water discharge. .
　以上のビデ洗浄装置１Ｅは、便器装置７の操作パネル７５等を操作することで、狭モード吐水を行うか、広モード吐水を行うかいずれかが選択され、作動する。
　狭モード吐水を行うように操作された場合は、機能部７４内の制御部により流路切り替え弁が操作され、狭モード流路１３に給水される。狭モード流路１３を流通する洗浄水は、狭域吐水孔群２１０の吐水孔２０ａから使用者の局部近傍に向けて吐水される。
　広モード吐水を行うように操作された場合は、機能部７４内の制御部により流路切り替え弁が操作され、広モード流路１４に給水される。広モード流路１４を流通する洗浄水は、広域吐水孔群２２０のコア部２２０ａ及び周辺部２２０ｂの吐水孔２０ｂから使用者の局部の周囲及び局部の前方側及び後方側に向けて吐水される。このとき、広域吐水孔群２２０から吐水される洗浄水の着水範囲のうち、コア着水部２２１の着水力の方が、周辺着水部２２２の着水力よりも高くなっている。 The above bidet cleaning device 1E operates by operating the operation panel 75 or the like of the toilet bowl device 7 to select either the narrow mode water discharge or the wide mode water discharge, and operates.
When the operation is performed so as to perform the narrow mode water discharge, the flow path switching valve is operated by the control unit in the function unit 74, and the narrow mode flow path 13 is supplied with water. The washing water flowing through the narrow mode flow path 13 is discharged from the water discharge holes 20a of the narrow water discharge hole group 210 toward the vicinity of the user's local area.
When the operation is performed to perform the wide mode water discharge, the flow path switching valve is operated by the control unit in the function unit 74, and water is supplied to the wide mode flow path 14. The wash water flowing through the wide mode flow path 14 is discharged from the core part 220a of the wide area water discharge hole group 220 and the water discharge holes 20b of the peripheral part 220b toward the periphery of the user's local area and toward the front side and the rear side of the local area. . At this time, the landing power of the core landing section 221 is higher than that of the peripheral landing section 222 in the landing range of the washing water discharged from the wide area water discharging hole group 220.
　第８実施形態によれば、以下の効果を奏する。
　第８実施形態では、ビデ洗浄装置１Ｅを、便器７１後部に対して前後方向に進退可能に設けられ、前後方向を長手方向とする長尺のノズル部１２と、ノズル部１２の先端側に配置され、使用者の身体局部に対して洗浄水を吐水する複数の吐水孔群２と、を含んで構成した。また、複数の吐水孔群２を、身体局部近傍の所定の範囲に対して吐水する狭モード吐水用の狭域吐水孔群２１０と、記所定の範囲よりも広い範囲に吐水する広モード吐水用の広域吐水孔群２２０と、を有し、広域吐水孔群２２０から吐水される洗浄水が使用者に着水する広モード着水範囲のうち、狭域吐水孔群２１０から吐水される洗浄水が使用者に着水する狭モード着水範囲と重なるコア着水部２２１における着水力を、広モード着水範囲のうち、前記狭モード着水範囲と重ならない周辺着水部２２２よりも高くした。
　広域吐水孔群２２０が、複数の吐水孔２０を有しているので、広域吐水孔群２２０内で着水力に高低の違いを有するように分布させることができる。具体的には、広モード着水範囲Ｗ１のうち、狭モード着水範囲Ｎ１と重なるコア着水部２２１の着水力を、広モード着水範囲Ｗ１のうち、狭モード着水範囲Ｎ１と重ならない周辺着水部２２２の着水力よりも高くすることができる。これにより、広モード吐水中に、最も汚れが付着しやすい部分を、効率良く効果的に洗浄することができる。 According to the eighth embodiment, the following effects can be obtained.
In the eighth embodiment, the bidet cleaning device 1E is provided so as to be able to advance and retreat in the front-rear direction with respect to the rear portion of the toilet 71, and is disposed on the tip side of the long nozzle portion 12 having the front-rear direction as the longitudinal direction. And a plurality of water discharge hole groups 2 for discharging cleaning water to the body part of the user. In addition, a plurality of water discharge hole groups 2, a narrow mode water discharge hole group 210 for discharging water to a predetermined range near the body part, and a wide mode water discharge for discharging water over a wider range than the predetermined range. Of the wide-area water discharge hole group 220, and of the wash water discharged from the narrow-area water discharge hole group 210 in the wide mode water landing range where the wash water discharged from the wide area water discharge hole group 220 lands on the user. The landing power at the core landing section 221 that overlaps the narrow mode landing range where the user lands on the user is higher than the peripheral landing section 222 that does not overlap the narrow mode landing range of the wide mode landing range. .
Since the wide area water discharge hole group 220 has the plurality of water discharge holes 20, the water discharge force can be distributed in the wide area water discharge hole group 220 so as to have a difference in height. Specifically, the landing power of the core landing section 221 overlapping the narrow mode landing range N1 in the wide mode landing range W1 does not overlap with the narrow mode landing range N1 in the wide mode landing range W1. The water landing force of the peripheral water landing section 222 can be made higher. This makes it possible to efficiently and effectively wash a portion to which dirt is most likely to adhere in the wide mode discharge.
　第８実施形態では、狭モード着水範囲Ｎ１における着水力を、広モード着水範囲Ｗ１における周辺着水部２２２の着水力よりも高くした。これにより、狭モード吐水を単独で行った場合でも、広モード吐水を単独で行った場合のいずれでも、最も汚れが付着しやすい部分を、効率良く効果的に洗浄することができる。 In the eighth embodiment, the landing power in the narrow mode landing range N1 is higher than that of the peripheral landing section 222 in the wide mode landing range W1. This makes it possible to efficiently and effectively clean a portion to which dirt is most likely to adhere, regardless of whether the narrow mode water discharge is performed alone or the wide mode water discharge is performed alone.

In the figure, narrow mode water discharge is indicated by N, and wide mode water discharge is indicated by W. In the description of the ninth embodiment and subsequent embodiments, description of parts common to the eighth embodiment will be omitted.
　第９実施形態では、狭モード吐水における狭モード着水範囲Ｎ１の着水力と、広モード吐水における広モード着水範囲Ｗ１のコア着水部２２１の着水力とが、略同一の着水力を有するように流量及び流速が調整されている。
　第９実施形態によれば、狭モード吐水と広モード吐水とを使用者が切り替えた場合に、局部周辺にかかる刺激の強さに変化がないので、違和感のない快適な洗浄を行うことができる。 In the ninth embodiment, the landing power of the core landing section 221 in the narrow mode landing range N1 in the narrow mode water discharging and the core landing section 221 in the wide mode landing range W1 in the wide mode discharging have substantially the same landing power. The flow rate and the flow rate are adjusted as described above.

　図２２は、第１０実施形態に係るヘッド部１１Ｆの上面図である。第１０実施形態では、広モード吐水は、狭域吐水孔群２１０Ｆ及び広域吐水孔群２２０Ｆの両方から同時に吐水される同時吐水モードを有する。また、第１０実施形態では、狭域吐水孔群２１０Ｆにおける吐水孔２０ａそれぞれの口径は、広域吐水孔群２２０Ｆにおける吐水孔２０ｂそれぞれの口径よりも小さく形成されており、広域吐水孔群２２０Ｆを構成する吐水孔２０ｂの開口面積は、狭域吐水孔群２１０Ｆにおける吐水孔２０ａの開口面積よりも大きい。 FIG. 22 is a top view of the head 11F according to the tenth embodiment. In the tenth embodiment, the wide mode water discharge has a simultaneous water discharge mode in which water is simultaneously discharged from both the narrow area water discharge hole group 210F and the wide area water discharge hole group 220F. In the tenth embodiment, the diameter of each of the water discharge holes 20a in the narrow area water discharge hole group 210F is formed smaller than the diameter of each of the water discharge holes 20b in the wide area water discharge hole group 220F. The opening area of the water discharge hole 20b is larger than the opening area of the water discharge hole 20a in the narrow area water discharge hole group 210F.
　同時吐水モードにおいて、広域吐水孔群２２０Ｆから吐水される洗浄水の着水力は、狭域吐水孔群２１０Ｆから吐水される洗浄水の着水力よりも小さくなるように流速及び水量が調整されている。 In the simultaneous water discharge mode, the flow velocity and the amount of water are adjusted such that the landing power of the cleaning water discharged from the wide area water discharging hole group 220F is smaller than the landing power of the cleaning water discharged from the narrow area discharging hole group 210F. .
　図２３は、第１０実施形態に係るビデ洗浄装置１Ｆの使用の状態を示す模式図である。図２２及び図２３に示すように、広域吐水孔群２２０Ｆは、狭域吐水孔群２１０Ｆを取り囲むように吐水する。広域吐水孔群２２０Ｆから吐水される洗浄水の方が、狭域吐水孔群２１０Ｂから吐水される洗浄水よりも流速が遅く、着水力が小さくなっている。このため、狭域吐水孔群２１０Ｆから吐水される水に勢いがあって局部の近傍に当たって跳ね返るようなことがあったとしても、その周囲の広域吐水孔群２２０Ｆから遅く吐水される洗浄水によって跳ね返った飛沫がブロックされ、洗浄水の飛び散りが防止される。 FIG. 23 is a schematic diagram showing a use state of the bidet cleaning device 1F according to the tenth embodiment. As shown in FIGS. 22 and 23, the wide area water discharge hole group 220F discharges water so as to surround the narrow area water discharge hole group 210F. The flow rate of the wash water spouted from the wide area spout group 220F is lower than that of the wash water spouted from the narrow area spout group 210B, and the landing power is smaller. For this reason, even if the water discharged from the narrow water discharge hole group 210F has a momentum and rebounds in the vicinity of the local area, the water is repelled by the wash water that is discharged late from the wide water discharge hole group 220F around the water discharge hole group. Droplets are blocked, preventing splashing of washing water.
