Description

ノズル装置とそれを使用した衛生洗浄装置Nozzle device and sanitary washing device using it
 本発明は、人体の局部を洗浄するノズル装置とそれを使用した衛生洗浄装置に関する。 The present invention relates to a nozzle device for cleaning a local part of a human body and a sanitary cleaning device using the nozzle device.
 従来、この種のノズル装置として、吐出口と、ノズルヘッドと、3個のシリンダと、駆動部とで構成されるノズル装置が提案されている(例えば、特許文献1参照)。吐出口は、ノズル装置の先端部に設けられ、局部を洗浄する洗浄水を噴出する。ノズルヘッドは、ノズル装置の後端部に設けられ、洗浄水を供給する給水チューブが接続されている。シリンダは、ノズルヘッドを格納するとともに、ノズルヘッドの進退移動のガイドを構成する。具体的には、シリンダは、摺動可能な第1および第2のシリンダとノズル装置の基部に固定された第3のシリンダで構成されている。駆動部は、ノズルヘッドを進退移動させる。具体的には、駆動部は、ノズルヘッドの後端部に結合されてシリンダの内部を貫通する可撓ラックと、可撓ラックを駆動する駆動ユニットで構成されている。そして、駆動部の駆動ユニットで、可撓ラックを進退駆動させる。これにより、ノズルヘッドと第1および第2のシリンダが進退移動される構成となっている。 Conventionally, as this type of nozzle device, a nozzle device including a discharge port, a nozzle head, three cylinders, and a drive unit has been proposed (for example, see Patent Document 1). A discharge port is provided in the front-end | tip part of a nozzle apparatus, and ejects the washing water which wash | cleans a local part. The nozzle head is provided at the rear end of the nozzle device, and is connected to a water supply tube that supplies cleaning water. The cylinder stores the nozzle head and constitutes a guide for the forward and backward movement of the nozzle head. Specifically, the cylinder includes a slidable first and second cylinder and a third cylinder fixed to the base of the nozzle device. The drive unit moves the nozzle head forward and backward. Specifically, the drive unit includes a flexible rack that is coupled to the rear end of the nozzle head and passes through the inside of the cylinder, and a drive unit that drives the flexible rack. Then, the flexible rack is driven forward and backward by the drive unit of the drive unit. As a result, the nozzle head and the first and second cylinders are configured to move forward and backward.
 しかしながら、従来のノズル装置の構成は、ノズルヘッドの進退移動のガイドとなるシリンダは、ノズル装置の基部に固定されている第3のシリンダのみである。そして、第2のシリンダは第3のシリンダに摺動可能に支持され、第1のシリンダは第2のシリンダに摺動可能に支持された構成である。この場合、ノズルヘッドと第1のシリンダ間およびそれぞれのシリンダ間との接合部におけるクリアランスのバラツキおよび変動により、ノズルヘッドの移動軌跡にバラツキが生じる。そのため、ノズルヘッドの吐出口の位置を充分に安定させることができない。その結果、被洗浄対象に対して的確に洗浄水を噴出することができないため、洗浄位置の位置決め精度という観点からは未だ改善の余地があった。 However, in the configuration of the conventional nozzle device, the cylinder serving as a guide for the forward and backward movement of the nozzle head is only the third cylinder fixed to the base of the nozzle device. The second cylinder is slidably supported by the third cylinder, and the first cylinder is slidably supported by the second cylinder. In this case, the movement trajectory of the nozzle head varies due to variations and fluctuations in the clearance between the nozzle head and the first cylinder and between the respective cylinders. Therefore, the position of the discharge port of the nozzle head cannot be sufficiently stabilized. As a result, since the cleaning water cannot be ejected accurately to the object to be cleaned, there is still room for improvement from the viewpoint of positioning accuracy of the cleaning position.

 このとき、図5に示すように、支持部600の傾斜部620に配置されるノズル部700を案内するガイドレール621は、断面が略T字形状(T字形状を含む)に形成されている。さらに、支持部600の傾斜部620に配置される可撓ラック810を案内するラックガイド622は、断面が一方の側面が開放された略コの字形状(コの字形状を含む)に形成されている。これにより、ラックガイド622は、可撓ラック810の上下面と他方の側面を規制して、可撓ラック810を案内する。 At this time, as shown in FIG. 5, the guide rail 621 that guides the nozzle portion 700 disposed on the inclined portion 620 of the support portion 600 has a substantially T-shaped cross section (including a T-shape). . Furthermore, the rack guide 622 that guides the flexible rack 810 disposed on the inclined portion 620 of the support portion 600 is formed in a substantially U-shape (including a U-shape) with a cross section open on one side surface. ing. Thereby, the rack guide 622 regulates the upper and lower surfaces and the other side surface of the flexible rack 810 to guide the flexible rack 810.
 また、ラックガイド622は、図6に示すように、支持部600の傾斜部620から支持部600の後部の縦辺部640および底辺部610に亘って連続して形成されている。このとき、支持部600の傾斜部620と縦辺部640を接続するコーナおよび縦辺部640と底辺部610を接続するコーナは、略円弧形状(円弧形状を含む)に形成されている。なお、支持部600の縦辺部640と底辺部610に形成されるラックガイド622の断面形状も、傾斜部620のラックガイド622と同様に、略コの字形状(コの字形状を含む)に形成されている。しかし、ラックガイド622の開放された側面は、傾斜部620では左側側面であるが、縦辺部640と底辺部610とは反対の右側側面を開放している。そして、支持部600の縦辺部640と底辺部610のラックガイド622の開放面は、図5に示す別部材からなる支持部蓋660により閉塞される。 Further, as shown in FIG. 6, the rack guide 622 is formed continuously from the inclined portion 620 of the support portion 600 to the vertical side portion 640 and the bottom side portion 610 of the rear portion of the support portion 600. At this time, the corner connecting the inclined portion 620 and the vertical side portion 640 of the support portion 600 and the corner connecting the vertical side portion 640 and the bottom side portion 610 are formed in a substantially arc shape (including an arc shape). The cross-sectional shape of the rack guide 622 formed on the vertical side portion 640 and the bottom side portion 610 of the support portion 600 is also substantially U-shaped (including the U-shape), similarly to the rack guide 622 of the inclined portion 620. Is formed. However, the opened side surface of the rack guide 622 is the left side surface in the inclined portion 620, but the right side surface opposite to the vertical side portion 640 and the bottom side portion 610 is open. The open surfaces of the vertical side portion 640 of the support portion 600 and the rack guide 622 of the bottom side portion 610 are closed by a support portion lid 660 made of another member shown in FIG.
 また、図6に示すように、可撓ラック810の上下方向の移動を規制するラックガイド622の高さ方向の寸法は、支持部600の傾斜部620と縦辺部640において、可撓ラック810の厚さより僅かに大きい寸法に形成されている。一方、支持部600の底辺部610のラックガイド622の高さ方向の寸法は、可撓ラック810の厚さより十分に大きい寸法で形成している。これにより、支持部600の底辺部610において、ラックガイド622と可撓ラック810との摺動に伴う抵抗を減少させている。 Further, as shown in FIG. 6, the height dimension of the rack guide 622 that restricts the vertical movement of the flexible rack 810 is the same as the flexible rack 810 at the inclined portion 620 and the vertical side portion 640 of the support portion 600. It is formed in a dimension slightly larger than the thickness. On the other hand, the height direction of the rack guide 622 of the bottom side portion 610 of the support portion 600 is formed to be sufficiently larger than the thickness of the flexible rack 810. Thereby, in the bottom side part 610 of the support part 600, the resistance accompanying sliding with the rack guide 622 and the flexible rack 810 is reduced.
 また、駆動部800は、ノズル部700に結合された可撓ラック810と、可撓ラック810と噛合するピニオンギア820と、ピニオンギア820を回転駆動する駆動モータ830で構成されている。これにより、駆動部800は、ノズル部700をガイドレール621に沿って進退移動させる。 The drive unit 800 includes a flexible rack 810 coupled to the nozzle unit 700, a pinion gear 820 that meshes with the flexible rack 810, and a drive motor 830 that rotationally drives the pinion gear 820. Accordingly, the driving unit 800 moves the nozzle unit 700 forward and backward along the guide rail 621.
 また、可撓ラック810は、例えばTPU(熱可塑性ポリウレタン)またはTPEE(ポリエステル系エラストマ)からなるTPE(熱可塑性エラストマ)などにより、一体に成型されて形成されている。そして、可撓ラック810は、全体として僅かに湾曲した帯状に形成され、湾曲形状の内周面には駆動部800のピニオンギア820と噛合する歯形が形成され、湾曲形状の外周面は平坦面に形成されている。なお、可撓ラック810の湾曲形状の外周面は、例えばPTFE(ポリテトラフルオロエチレン樹脂)などのフッ素樹脂でコーティングされている。これにより、可撓ラック810とラックガイド622との摩擦抵抗を低減させている。 Further, the flexible rack 810 is formed by being integrally molded with, for example, TPE (thermoplastic elastomer) made of TPU (thermoplastic polyurethane) or TPEE (polyester elastomer). The flexible rack 810 is formed in a slightly curved band shape as a whole, a tooth shape that meshes with the pinion gear 820 of the drive unit 800 is formed on the curved inner peripheral surface, and the curved outer peripheral surface is a flat surface. Is formed. The curved outer peripheral surface of the flexible rack 810 is coated with a fluorine resin such as PTFE (polytetrafluoroethylene resin). Thereby, the frictional resistance between the flexible rack 810 and the rack guide 622 is reduced.
 また、図6に示すように、支持部600の縦辺部640と底辺部610のコーナには、可撓ラック810と噛合して可撓ラック810を駆動するピニオンギア820と、ピニオンギア820を駆動する駆動モータ830が設置されている。このとき、駆動モータ830は、例えばステッピングモータで構成され、パルス信号により回転角度が制御される。ピニオンギア820は、ラックガイド622のコーナと同心となる位置に設置され、ピニオンギア820の中心に形成された軸受け部820aに駆動モータ830の回転軸が結合されている。これにより、駆動モータ830の回転が、ピニオンギア820を介して、噛合する可撓ラック810の歯形に伝達され、可撓ラック810を駆動する。 As shown in FIG. 6, a pinion gear 820 that meshes with the flexible rack 810 and drives the flexible rack 810 and a pinion gear 820 are provided at the corners of the vertical side portion 640 and the bottom side portion 610 of the support portion 600. A driving motor 830 for driving is installed. At this time, the drive motor 830 is composed of a stepping motor, for example, and the rotation angle is controlled by a pulse signal. The pinion gear 820 is installed at a position concentric with the corner of the rack guide 622, and the rotation shaft of the drive motor 830 is coupled to a bearing portion 820 a formed at the center of the pinion gear 820. Thereby, the rotation of the drive motor 830 is transmitted to the tooth profile of the meshing flexible rack 810 via the pinion gear 820 to drive the flexible rack 810.
 また、図9などに示すように、支持部600の傾斜部620の前端(抱持部630側)および後端(縦辺部側)の近傍には、前ストッパ受部623と後ストッパ受部624が形成されている。これにより、ノズルカバー720の摺動範囲を所定の範囲に規制する。 Further, as shown in FIG. 9 and the like, a front stopper receiving portion 623 and a rear stopper receiving portion are disposed in the vicinity of the front end (holding portion 630 side) and the rear end (vertical side portion side) of the inclined portion 620 of the support portion 600. 624 is formed. Thereby, the sliding range of the nozzle cover 720 is regulated to a predetermined range.
 また、図7や図8に示すように、支持部600の抱持部630の内周面と、ノズル部700のノズルカバー720の外周面との間には、隙間740が設けられている。そして、ノズル部700から噴出した洗浄水が抱持部630の内周面とノズル部700のノズルカバー720の外周面との間に形成される隙間740に流入する、これにより、洗浄水は、ノズル部700のノズルカバー720の外周面を洗浄し、排水口725から排出される。 7 and 8, a gap 740 is provided between the inner peripheral surface of the holding portion 630 of the support portion 600 and the outer peripheral surface of the nozzle cover 720 of the nozzle portion 700. Then, the cleaning water ejected from the nozzle unit 700 flows into a gap 740 formed between the inner peripheral surface of the holding unit 630 and the outer peripheral surface of the nozzle cover 720 of the nozzle unit 700. The outer peripheral surface of the nozzle cover 720 of the nozzle unit 700 is washed and discharged from the drain port 725.
 また、抱持部630の前方には、ノズル部700の進退により開閉するノズル蓋650を開閉自在に設けている。そして、ノズル部700が収納されている状態で、ノズル蓋650が閉塞することにより、ノズル部700が便などで汚染されることを防止する。 Further, a nozzle lid 650 that opens and closes by the advancement and retraction of the nozzle unit 700 is provided in front of the holding unit 630 so as to be freely opened and closed. Then, when the nozzle portion 700 is stored, the nozzle lid 650 is blocked to prevent the nozzle portion 700 from being contaminated with feces or the like.
 また、図4に示すように、支持部600の底辺部610には、給水継手611を設けている。給水継手611は、洗浄水供給部に接続する給水チューブ(図示せず)と、支持部600から流調弁900に洗浄水を供給する接続チューブ612と、を相互に接続する。さらに、給水継手611は、後述の摺動部を構成するスライダ750の摺動範囲の略中央(中央を含む)に対応するガイドレール621の中間位置より垂直下方の位置で、かつガイドレール621より十分に離れた位置に配置されている。この配置により、接続チューブ612の長さを短くすることができる。また、ノズル部700がガイドレール621に沿って進退する場合における接続チューブ612の変形を、少なくできる。さらに、接続チューブ612による抵抗を抑制できる。その結果、ノズル部700をガイドレール621に沿って、スムーズに摺動させることができる。 Further, as shown in FIG. 4, a water supply joint 611 is provided on the bottom side portion 610 of the support portion 600. The water supply joint 611 connects a water supply tube (not shown) connected to the cleaning water supply unit and a connection tube 612 that supplies the cleaning water from the support unit 600 to the flow control valve 900. Further, the water supply joint 611 is located at a position vertically below the intermediate position of the guide rail 621 corresponding to the approximate center (including the center) of the sliding range of the slider 750 constituting the sliding portion described later, and from the guide rail 621. It is located at a sufficiently distant position. With this arrangement, the length of the connection tube 612 can be shortened. Further, the deformation of the connection tube 612 when the nozzle portion 700 advances and retreats along the guide rail 621 can be reduced. Furthermore, resistance due to the connection tube 612 can be suppressed. As a result, the nozzle unit 700 can be smoothly slid along the guide rail 621.
 また、図8や図9に示すように、ノズル部700は、例えばABS(アクリロニトリル、ブタジエン、スチレン共重合合成樹脂)などの樹脂材料で成型され、ノズル本体710と、ノズルカバー720と、連結部730から構成されている。ノズル本体710は、例えば棒状で形成され、前方の先端部側に、お尻洗浄噴出口711と、ビデ洗浄噴出口712と、ノズルクリーニング噴出口713を備えている。さらに、ノズル本体710は、お尻洗浄噴出口711とビデ洗浄噴出口712およびノズルクリーニング噴出口713に連通する、お尻洗浄流路714とビデ洗浄流路715とノズルクリーニング流路716を備えている。ノズルカバー720は、例えば筒状に形成され、ノズル本体710の略全体(全体を含む)を覆う。連結部730は、後述するように、ノズル本体710とノズルカバー720を係合して、ノズル本体710でノズルカバー720を牽引する。 Further, as shown in FIGS. 8 and 9, the nozzle portion 700 is molded of a resin material such as ABS (acrylonitrile, butadiene, styrene copolymer synthetic resin), for example, and includes a nozzle body 710, a nozzle cover 720, and a connecting portion. 730. The nozzle body 710 is formed, for example, in a rod shape, and includes a butt cleaning jet 711, a bidet cleaning jet 712, and a nozzle cleaning jet 713 on the front end side. Further, the nozzle body 710 includes a butt cleaning channel 714, a bidet cleaning channel 715, and a nozzle cleaning channel 716 communicating with the butt cleaning nozzle 711, the bidet cleaning nozzle 712, and the nozzle cleaning nozzle 713. Yes. The nozzle cover 720 is formed in a cylindrical shape, for example, and covers substantially the entire nozzle body 710 (including the whole). As will be described later, the connecting portion 730 engages the nozzle body 710 and the nozzle cover 720 and pulls the nozzle cover 720 with the nozzle body 710.
 そして、ノズル部700は、ノズル部700の前方側が支持部600の抱持部630に挿入した状態で支持され、後部側がガイドレール621に懸架された状態で摺動自在に設置されている。このとき、ノズル部700は、図4、図7、図9に示すノズル部700を抱持部630より後方に収容された収納位置と、図11、図12、図14に示すノズル部700が抱持部630より突出したお尻洗浄位置と、図16、図17、図19に示すビデ洗浄位置との間を進退可能に移動する。 The nozzle unit 700 is supported in a state where the front side of the nozzle unit 700 is inserted into the holding unit 630 of the support unit 600 and is slidably installed in a state where the rear side is suspended by the guide rail 621. At this time, the nozzle unit 700 includes a storage position in which the nozzle unit 700 shown in FIGS. 4, 7, and 9 is stored behind the holding unit 630, and the nozzle unit 700 shown in FIGS. 11, 12, and 14. It moves so as to be able to advance and retreat between the buttocks cleaning position protruding from the holding portion 630 and the bidet cleaning position shown in FIGS.
 また、図9に示すように、ノズルカバー720は、ノズルカバー本体721と連結部材722とで構成されている。ノズルカバー本体721は、例えばステンレスの薄板を円筒形状に成型して形成され、先端面が閉塞面で、後端面は開放面で構成されている。連結部材722は、例えばPOMなどの樹脂材料で略円筒形状(円筒形状を含む)に成型され、その端面部の相対する位置に一対のノズル本体710と係合する連結片723(図10参照)が形成されている。さらに、連結部材722の後端右側には、ノズルカバー720の摺動範囲を規制するノズルカバーストッパ726が一体に形成されている。そして、ノズルカバーストッパ726が支持部600に形成された前ストッパ受部623と後ストッパ受部624に当接することにより、ノズルカバー720の摺動範囲が規制される。 Further, as shown in FIG. 9, the nozzle cover 720 includes a nozzle cover main body 721 and a connecting member 722. The nozzle cover main body 721 is formed, for example, by molding a thin stainless steel plate into a cylindrical shape, and the front end surface is a closed surface and the rear end surface is an open surface. The connecting member 722 is molded into a substantially cylindrical shape (including a cylindrical shape) using a resin material such as POM, for example, and a connecting piece 723 that engages with a pair of nozzle main bodies 710 at opposite positions of the end face portions (see FIG. 10). Is formed. Further, a nozzle cover stopper 726 for restricting the sliding range of the nozzle cover 720 is integrally formed on the right side of the rear end of the connecting member 722. The nozzle cover stopper 726 comes into contact with the front stopper receiving portion 623 and the rear stopper receiving portion 624 formed on the support portion 600, whereby the sliding range of the nozzle cover 720 is restricted.
 また、ノズルカバー720の連結部材722の一部は、ノズルカバー本体721の後端に設けた開放面の開口からノズルカバー本体721内に挿入された状態で固定されて一体化されている。 Further, a part of the connecting member 722 of the nozzle cover 720 is fixed and integrated in a state of being inserted into the nozzle cover body 721 from the opening of the open surface provided at the rear end of the nozzle cover body 721.
 また、図7や図8に示すように、ノズルカバー本体721の前方上面には、ノズル本体710のお尻洗浄噴出口711とビデ洗浄噴出口712と対向可能な位置に噴出開口724が1個設けられている。ノズルカバー本体721の前方下面には、ノズルカバー本体721内に流出した洗浄水を外部に排出する排水口725が設けられている。 Further, as shown in FIGS. 7 and 8, one nozzle opening 724 is provided on the front upper surface of the nozzle cover main body 721 at a position that can face the bottom cleaning jet outlet 711 and the bidet cleaning jet outlet 712 of the nozzle main body 710. Is provided. On the front lower surface of the nozzle cover main body 721, a drain outlet 725 is provided for discharging the wash water that has flowed into the nozzle cover main body 721 to the outside.
 また、ノズル本体710は、例えばABSなどの樹脂材料で成型により形成されている。このとき、ノズル本体710は、ノズルカバー720の内径より僅かに小さい外径で形成される。これにより、ノズルカバー720にノズル本体710を挿入した状態で、ノズル本体710とノズルカバー720との互いにスムーズな摺動を可能としている。 The nozzle body 710 is formed by molding with a resin material such as ABS, for example. At this time, the nozzle body 710 is formed with an outer diameter slightly smaller than the inner diameter of the nozzle cover 720. Accordingly, the nozzle body 710 and the nozzle cover 720 can slide smoothly with each other in a state where the nozzle body 710 is inserted into the nozzle cover 720.
 また、図8に示すように、ノズル本体710の先端部側の上面には、お尻洗浄噴出口711と、その後方に間隔を開けてビデ洗浄噴出口712が配置されている。さらに、図9に示すように、ビデ洗浄噴出口712の後方の左側面には、ノズルクリーニング噴出口713が設置されている。 Further, as shown in FIG. 8, a bottom cleaning jet outlet 711 and a bidet cleaning jet outlet 712 are arranged on the upper surface of the nozzle body 710 on the front end side with a space behind it. Further, as shown in FIG. 9, a nozzle cleaning jet 713 is provided on the left side surface behind the bidet cleaning jet 712.
 また、ノズル本体710の内部には、図7や図9に示すように後端部から先端部まで略直線状(直線状を含む)に配置された、お尻洗浄流路714と、ビデ洗浄流路715と、ノズルクリーニング流路716の3本の流路が、図5に示すような配置で形成されている。具体的には、お尻洗浄流路714は、ノズル本体710の右側下方に配置される。そして、図13に示すように、お尻洗浄流路714は、先端部近傍で、ノズル本体710の上面方向へ流路を屈曲させ、お尻洗浄噴出口711に連通されている。これにより、お尻洗浄噴出口711から噴出した洗浄水は、対向して配置されたノズルカバー720の噴出開口724を通過して上方に向かって噴出される。 Further, inside the nozzle main body 710, as shown in FIG. 7 and FIG. 9, a hip cleaning channel 714 arranged in a substantially straight line (including a straight line) from the rear end to the front end, and a bidet cleaning Three channels, a channel 715 and a nozzle cleaning channel 716, are formed as shown in FIG. Specifically, the buttocks cleaning channel 714 is disposed on the lower right side of the nozzle body 710. As shown in FIG. 13, the buttocks cleaning channel 714 is communicated with the buttocks cleaning jet port 711 by bending the channel toward the top surface of the nozzle body 710 near the tip. As a result, the washing water ejected from the buttocks washing ejection port 711 passes through the ejection opening 724 of the nozzle cover 720 disposed so as to be opposed and is ejected upward.
 一方、図5に示すビデ洗浄流路715は、ノズル本体710の右側上方に配置される。そして、図18に示すように、ビデ洗浄流路715は、先端部近傍で、ノズル本体710の上面方向へ流路を屈曲させ、ビデ洗浄噴出口712に連通されている。これにより、ビデ洗浄噴出口712から噴出した洗浄水は、対向して配置されたノズルカバー720の噴出開口724を通過して上方に向かって噴出される。 On the other hand, the bidet cleaning flow path 715 shown in FIG. 5 is arranged on the upper right side of the nozzle body 710. As shown in FIG. 18, the bidet cleaning channel 715 is communicated with the bidet cleaning nozzle 712 by bending the channel toward the top surface of the nozzle body 710 near the tip. As a result, the washing water ejected from the bidet washing ejection port 712 passes through the ejection opening 724 of the nozzle cover 720 disposed so as to face and is ejected upward.
 さらに、図5に示すノズルクリーニング流路716は、ノズル本体710の左側に配置される。そして、図9や図19に示すように、ノズルクリーニング流路716は、先端部近傍で、ノズル本体710の左側へ流路を屈曲させ、ノズルクリーニング噴出口713に連通されている。これにより、ノズルクリーニング噴出口713から噴出した洗浄水は、ノズルカバー720の内部に噴出され、ノズルカバー720の排水口725からノズルカバー720の外部に放出される。つまり、ノズルクリーニング噴出口713から噴出した洗浄水は、ノズル部700とその周辺の清掃に使用される。 5 is disposed on the left side of the nozzle body 710. As shown in FIGS. 9 and 19, the nozzle cleaning channel 716 is communicated with the nozzle cleaning jet 713 by bending the channel toward the left side of the nozzle body 710 in the vicinity of the tip. Accordingly, the cleaning water ejected from the nozzle cleaning ejection port 713 is ejected into the nozzle cover 720 and discharged from the drain port 725 of the nozzle cover 720 to the outside of the nozzle cover 720. That is, the washing water ejected from the nozzle cleaning ejection port 713 is used for cleaning the nozzle portion 700 and its surroundings.
 また、図4や図7に示すように、ノズル本体710の後端面には、流調弁900が設置されている。流調弁900は、例えばディスクタイプの弁本体910と、切り替え動作を駆動する、例えばステッピングモータ920とで構成されている。そして、流調弁900は、お尻洗浄流路714と、ビデ洗浄流路715と、ノズルクリーニング流路716を選択的に切り替えて、洗浄水を供給する。 Further, as shown in FIG. 4 and FIG. 7, a flow control valve 900 is installed on the rear end surface of the nozzle body 710. The flow control valve 900 includes, for example, a disc type valve main body 910 and, for example, a stepping motor 920 that drives a switching operation. The flow control valve 900 selectively supplies the cleaning water by selectively switching the buttocks cleaning channel 714, the bidet cleaning channel 715, and the nozzle cleaning channel 716.
 さらに、流調弁900の弁本体910の外郭は、例えばPOMなどの樹脂材料で、成型されている。そして、流調弁900の弁本体910の上部には、一体に成型されたノズル部700をガイドレール621に懸架し摺動部を構成するスライダ750と、ノズル部700と可撓ラック810とを係合させる係合片751が配置されている。 Furthermore, the outer shell of the valve body 910 of the flow control valve 900 is molded from a resin material such as POM, for example. The upper part of the valve body 910 of the flow control valve 900 includes a slider 750 that forms a sliding part by suspending an integrally molded nozzle part 700 on a guide rail 621, a nozzle part 700, and a flexible rack 810. An engagement piece 751 to be engaged is disposed.
 スライダ750は、図5に示すように、略T字形状(T字形状を含む)のガイドレール621を抱持するように、断面が略C字形状(C字形状を含む)に形成されている。そして、スライダ750の内周面の両側端部750a近傍のみが、ガイドレール621の上下面と接触するような寸法で形成されている。さらに、スライダ750の中央部は、ガイドレール621と間隙が生じるように凹陥した断面の凹部750bが形成されている。これにより、スライダ750とガイドレール621との接触面積を減少させ、摺動抵抗を低減している。 As shown in FIG. 5, the slider 750 has a substantially C-shaped (including C-shaped) cross section so as to hold a guide rail 621 having a substantially T-shaped (including T-shaped) guide rail. Yes. Only the vicinity of both end portions 750 a of the inner peripheral surface of the slider 750 is formed so as to contact the upper and lower surfaces of the guide rail 621. Furthermore, a concave portion 750b having a cross section recessed so as to form a gap with the guide rail 621 is formed at the center of the slider 750. Thereby, the contact area between the slider 750 and the guide rail 621 is reduced, and the sliding resistance is reduced.
 また、上述したように、スライダ750の前端部に係合片751が、一体に形成されている。そして、図6に示すように、可撓ラック810は、係合片751の後方に配置されている。これにより、可撓ラック810からスライダ750に付加される駆動力は、係合片751を介して、常にスライダ750の前端部に加えられる。つまり、ガイドレール621に挿入されスライダ750は、ガイドレール621に沿って摺動可能となる。 As described above, the engagement piece 751 is integrally formed at the front end of the slider 750. As shown in FIG. 6, the flexible rack 810 is disposed behind the engagement piece 751. Accordingly, the driving force applied from the flexible rack 810 to the slider 750 is always applied to the front end portion of the slider 750 via the engagement piece 751. That is, the slider 750 inserted into the guide rail 621 can slide along the guide rail 621.
 さらに、可撓ラック810と係合されたスライダ750の係合片751は、ラックガイド622の内部に配置される。そして、可撓ラック810は、ピニオンギア820を介して駆動モータ830で駆動される。これにより、係合片751がラックガイド622の内部で前後に摺動し、ノズル部700がガイドレール621に沿って前後に摺動する。 Further, the engagement piece 751 of the slider 750 engaged with the flexible rack 810 is disposed inside the rack guide 622. The flexible rack 810 is driven by the drive motor 830 via the pinion gear 820. As a result, the engagement piece 751 slides back and forth inside the rack guide 622, and the nozzle portion 700 slides back and forth along the guide rail 621.
 このとき、ノズル部700の摺動時において、ノズル部700の前方は抱持部630により支持され、後方はスライダ750を介してガイドレール621に支持されている。これにより、可撓ラック810からノズル部700に付与される駆動力は、支持部600の前端と後端(具体的には、ノズル部700が移動する範囲におけるノズル本体710のホース接続部である給水口911の位置の最も前方に出た位置と最も後方に収納された位置)との中間に加えられるように構成される。そのため、ノズル部700に付与される駆動力により発生する、ガイドレール621とスライダ750との摩擦抵抗(摺動抵抗)を抑制することができる。この理由は、片側にホース接続部である給水口911と給水継手611とを集めて近接して配置した場合、ノズル部700の移動に伴ってホース接続部が近接すると、接続チューブ612のねじれ力が大きくなるため、ねじり力が摺動抵抗となる。つまり、ノズル部700が前後移動する場合、ホース接続部間の距離を均一に保つことが、摺動抵抗を小さくできる。理想的には、接続チューブ612が移動する軌跡である半円の中心に設けることが、好ましい。しかし、通常、ホース接続部の配置には制約がある。そこで、本実施の形態では、ノズル部700の摺動する移動区間の中央に、いずれか一方のホース接続部を設けることにより、ホース接続部間の距離を最も均一に保つことができる。その結果、ノズル部700をスムーズに摺動することができる。 At this time, when the nozzle part 700 slides, the front part of the nozzle part 700 is supported by the holding part 630, and the rear part is supported by the guide rail 621 via the slider 750. Accordingly, the driving force applied from the flexible rack 810 to the nozzle unit 700 is the front end and the rear end of the support unit 600 (specifically, the hose connection unit of the nozzle body 710 in the range in which the nozzle unit 700 moves). It is configured to be added in the middle of the position of the water supply port 911 that is located in the foremost position and the position that is stored in the rearmost position. Therefore, the frictional resistance (sliding resistance) between the guide rail 621 and the slider 750 that is generated by the driving force applied to the nozzle unit 700 can be suppressed. The reason for this is that when the water supply port 911 and the water supply joint 611 which are hose connection parts are gathered and arranged close to each other and the hose connection part comes close as the nozzle part 700 moves, the twisting force of the connection tube 612 Therefore, the torsional force becomes the sliding resistance. That is, when the nozzle part 700 moves back and forth, keeping the distance between the hose connection parts uniform can reduce the sliding resistance. Ideally, it is preferable that the connection tube 612 is provided at the center of a semicircle that is a trajectory of movement. However, the arrangement of the hose connection is usually limited. Therefore, in the present embodiment, the distance between the hose connection portions can be most uniformly maintained by providing any one of the hose connection portions in the center of the moving section in which the nozzle portion 700 slides. As a result, the nozzle part 700 can be smoothly slid.
 また、図4に示すように、流調弁900の弁本体910外面には、流調弁900に洗浄水を供給する給水口911が設置されている。そして、給水口911は、支持部600の給水継手611と連通する接続チューブ612と接続されている。これにより、洗浄水が、流調弁900により選択的に、ノズル部700の各流路に供給される。 As shown in FIG. 4, a water supply port 911 for supplying cleaning water to the flow control valve 900 is installed on the outer surface of the valve main body 910 of the flow control valve 900. The water supply port 911 is connected to a connection tube 612 that communicates with the water supply joint 611 of the support portion 600. Accordingly, the cleaning water is selectively supplied to each flow path of the nozzle unit 700 by the flow control valve 900.
 つぎに、本実施の形態におけるノズル部の連結部の構成および動作について、図10、図15および図20を用いて説明する。なお、連結部730は、上述したように、ノズルカバー720の連結部材722と、ノズル本体710の連結受部717で構成される。 Next, the configuration and operation of the connecting portion of the nozzle portion in the present embodiment will be described with reference to FIG. 10, FIG. 15, and FIG. As described above, the connecting portion 730 includes the connecting member 722 of the nozzle cover 720 and the connection receiving portion 717 of the nozzle body 710.
 まず、図10、図15および図20に示すように、連結受部717は、ノズル本体710の後端部の外周右側に形成されている。連結受部717は、例えば2本の略V字型(V字型を含む)の溝からなる、前凹陥部717aと後凹陥部717bが、前後に所定の間隔を開けて構成されている。なお、前凹陥部717aと後凹陥部717bの間隔は、お尻洗浄噴出口711とビデ洗浄噴出口712の間隔と等しい寸法で設けられる。 First, as shown in FIGS. 10, 15, and 20, the connection receiving portion 717 is formed on the right side of the outer periphery of the rear end portion of the nozzle body 710. The connection receiving portion 717 includes, for example, two substantially V-shaped (including V-shaped) grooves, and a front concave portion 717a and a rear concave portion 717b are formed at a predetermined interval in the front-rear direction. In addition, the space | interval of the front recessed part 717a and the back recessed part 717b is provided with the dimension equal to the space | interval of the hips washing | cleaning outlet 711 and the bidet washing | cleaning outlet 712.
 一方、ノズルカバー720の連結部材722は、略円筒状(円筒形状を含む)の、例えばPOMなどの樹脂材料で成型され、連結片723と、連結突起723aを備えている。連結片723は、ノズルカバー720の後部両側部で、後方に突出して形成されている。連結突起723aは、連結片723の後端部に、内方に突出した略V字形状(V字形状を含む)で形成されている。 On the other hand, the connecting member 722 of the nozzle cover 720 is formed of a resin material such as POM having a substantially cylindrical shape (including a cylindrical shape), and includes a connecting piece 723 and a connecting protrusion 723a. The connecting piece 723 is formed to protrude rearward at both sides of the rear portion of the nozzle cover 720. The connection protrusion 723a is formed at the rear end of the connection piece 723 in a substantially V shape (including a V shape) protruding inward.
 そして、ノズル本体710をノズルカバー720に挿入した状態において、ノズルカバー720の連結部材722の弾性により、連結突起723aがノズル本体710の連結受部717に常時押し当てられた状態となる。つまり、連結突起723aが、前凹陥部717a、または後凹陥部717bに係合した状態で、ノズル本体710とノズルカバー720が連結される。これにより、ノズルカバー720は、ノズル本体710に牽引されて移動することが可能となる。 In a state where the nozzle body 710 is inserted into the nozzle cover 720, the connection protrusion 723a is constantly pressed against the connection receiving portion 717 of the nozzle body 710 due to the elasticity of the connection member 722 of the nozzle cover 720. That is, the nozzle body 710 and the nozzle cover 720 are connected in a state where the connection protrusion 723a is engaged with the front recess 717a or the rear recess 717b. As a result, the nozzle cover 720 can be moved by being pulled by the nozzle body 710.
 このとき、図10や図15に示すように、連結突起723aが前凹陥部717aに入り込んでいる場合、図18に示すように、ノズル本体710のビデ洗浄噴出口712とノズルカバー720の噴出開口724が対向した状態となる。一方、図20に示すように、連結突起723aが後凹陥部717bに入り込んでいる場合、図8や図13に示すように、お尻洗浄噴出口711と噴出開口724が対向した状態となる。 At this time, as shown in FIGS. 10 and 15, when the connecting projection 723a enters the front recess 717a, as shown in FIG. 18, the bidet cleaning outlet 712 of the nozzle body 710 and the ejection opening of the nozzle cover 720 724 is in an opposing state. On the other hand, as shown in FIG. 20, when the connecting projection 723a enters the rear recess 717b, the buttocks cleaning jet 711 and the jet opening 724 face each other as shown in FIG. 8 and FIG.
 以上により、本実施の形態のノズル装置500が構成される。 Thus, the nozzle device 500 of the present embodiment is configured.
 <4>ノズル装置の動作および作用
 以下に、本実施の形態の衛生洗浄装置におけるノズル装置の動作および作用について、図4から図20を用いて説明する。
<4> Operation and Action of Nozzle Device Hereinafter, the operation and action of the nozzle device in the sanitary washing device of the present embodiment will be described with reference to FIGS.
 まず、図7に示すように、ノズル装置500を使用しない収納状態においては、ノズル本体710はガイドレール621の最も後部に位置し、ノズルカバー720も摺動範囲の最も後部に位置している。このとき、図10に示すように、ノズルカバー720のノズルカバーストッパ726は、支持部600の後部に設けた後ストッパ受部624に当接する。つまり、ノズル本体710とノズルカバー720が、最も後退した位置に配置されることになる。そこで、この位置を、以降では「収納位置」と称し、この状態を「収納状態」と称して説明する。このとき、連結片723の連結突起723aは、図10に示すように、連結受部717の前凹陥部717aに嵌入した状態で、ノズル本体710とノズルカバー720が連結されている。 First, as shown in FIG. 7, in a storage state where the nozzle device 500 is not used, the nozzle body 710 is located at the rearmost part of the guide rail 621, and the nozzle cover 720 is also located at the rearmost part of the sliding range. At this time, as shown in FIG. 10, the nozzle cover stopper 726 of the nozzle cover 720 contacts the rear stopper receiving portion 624 provided at the rear portion of the support portion 600. That is, the nozzle body 710 and the nozzle cover 720 are disposed at the most retracted position. Therefore, this position is hereinafter referred to as a “storage position”, and this state is referred to as a “storage state”. At this time, as shown in FIG. 10, the nozzle main body 710 and the nozzle cover 720 are connected to each other with the connection protrusion 723 a of the connection piece 723 fitted in the front recess 717 a of the connection receiving portion 717.
 つぎに、ノズル装置500の収納状態から洗浄を開始する場合について、図7、図8を用いて説明する。 Next, a case where cleaning is started from the storage state of the nozzle device 500 will be described with reference to FIGS.
 まず、使用者が洗浄を指示する操作スイッチ212を操作する。これにより、制御部230が、各部の制御を開始する。 First, the user operates the operation switch 212 for instructing cleaning. Thereby, the control part 230 starts control of each part.
 具体的には、まず、制御部230は、止水電磁弁243と流調弁900を駆動して、お尻洗浄流路714に洗浄水を供給する。そして、お尻洗浄噴出口711より抱持部630の内周面に向かって洗浄水を噴出させる。 Specifically, first, the control unit 230 drives the water stop solenoid valve 243 and the flow control valve 900 to supply cleaning water to the buttocks cleaning flow path 714. Then, washing water is ejected from the buttocks washing ejection port 711 toward the inner peripheral surface of the holding portion 630.
 このとき、噴出した洗浄水は抱持部630の内周面で反射して、ノズルカバー本体721の外周面と抱持部630内周面との隙間740を流れる。これにより、主にノズルカバー本体721の外周面の汚れを除去する。 At this time, the jetted washing water is reflected by the inner peripheral surface of the holding portion 630 and flows through the gap 740 between the outer peripheral surface of the nozzle cover main body 721 and the inner peripheral surface of the holding portion 630. As a result, dirt on the outer peripheral surface of the nozzle cover main body 721 is mainly removed.
 そして、制御部230は、所定時間が経過した後、流調弁900を制御して洗浄水の供給を停止する。この動作を、「ノズル前洗浄」と称する。この「ノズル前洗浄」は、ノズルカバー本体721の外周面の洗浄とともに、温水タンク245以降の流路に滞溜している冷水などの排出を目的としている。これにより、「ノズル前洗浄」が終了する。 Then, after a predetermined time has elapsed, the control unit 230 controls the flow control valve 900 to stop the supply of cleaning water. This operation is referred to as “nozzle pre-cleaning”. This “nozzle pre-cleaning” is aimed at cleaning the outer peripheral surface of the nozzle cover main body 721 and discharging cold water or the like remaining in the flow path after the hot water tank 245. Thereby, “nozzle pre-cleaning” is completed.
 つぎに、制御部230は、駆動モータ830を正回転させてノズル本体710を前方に移動させる。このとき、ノズルカバー720の連結片723の連結突起723aは、連結受部717の前凹陥部717aに嵌入した状態が保たれている。これにより、ノズルカバー720は、ノズル本体710に牽引され一体化した状態で前方に移動する。 Next, the controller 230 rotates the drive motor 830 in the forward direction to move the nozzle body 710 forward. At this time, the connection protrusion 723a of the connection piece 723 of the nozzle cover 720 is kept in a state of being fitted into the front recessed portion 717a of the connection receiving portion 717. Thereby, the nozzle cover 720 moves forward while being pulled and integrated with the nozzle body 710.
 以下に、使用者が設定した操作がお尻洗浄、ビデ洗浄およびノズルクリーニング洗浄に分けて、動作を説明する。 Hereafter, the operation set by the user is divided into hip cleaning, bidet cleaning and nozzle cleaning cleaning, and the operation will be described.
 まず、使用者が設定した操作がお尻洗浄の操作であった場合について、説明する。 First, the case where the operation set by the user is the buttocks cleaning operation will be described.
 図11、図12、図14に示すように、ノズル本体710およびノズルカバー720は、予め設定された制御シーケンスにしたがい、原点状態から駆動モータ830の回転数が設定値に達するまで、前方に移動して停止する。このとき、ノズルカバー720に設けたノズルカバーストッパ726は、支持部600の前ストッパ受部623に接触して停止した状態にある。つまり、図13に示すように、お尻洗浄噴出口711が、ノズルカバー本体721の噴出開口724と対向した状態となる。この位置が、「お尻洗浄位置」となる。 As shown in FIGS. 11, 12, and 14, the nozzle body 710 and the nozzle cover 720 move forward from the origin state until the rotational speed of the drive motor 830 reaches a set value according to a preset control sequence. Then stop. At this time, the nozzle cover stopper 726 provided on the nozzle cover 720 is in a stopped state in contact with the front stopper receiving portion 623 of the support portion 600. That is, as shown in FIG. 13, the buttocks cleaning outlet 711 faces the outlet opening 724 of the nozzle cover body 721. This position is the “butt cleaning position”.
 つぎに、「お尻洗浄位置」に配置された状態で、制御部230は、止水電磁弁243と流調弁900を制御して、お尻洗浄流路714に洗浄水を通水して、お尻洗浄を開始する。そして、お尻洗浄噴出口711から噴出した洗浄水は、ノズルカバー本体721の噴出開口724に接触せずに通過して、上方に噴射される。 Next, the control unit 230 controls the water stop solenoid valve 243 and the flow control valve 900 to flow the cleaning water into the buttocks cleaning flow path 714 in the state of being arranged at the “butt cleaning position”. Start ass cleaning. Then, the washing water ejected from the buttocks washing ejection port 711 passes without contacting the ejection opening 724 of the nozzle cover body 721 and is ejected upward.
 このとき、図13に示すように、ビデ洗浄噴出口712は、ノズルカバー本体721によって覆われている状態である。そのため、お尻洗浄によって生じた汚水が、ビデ洗浄噴出口712に直接かかることを防止できる。これにより、ビデ洗浄噴出口712を清潔に保つことができる。 At this time, as shown in FIG. 13, the bidet cleaning jet outlet 712 is covered with the nozzle cover main body 721. Therefore, it is possible to prevent the sewage generated by the buttocks cleaning from being applied directly to the bidet cleaning spout 712. Thereby, the bidet washing jet outlet 712 can be kept clean.
 つぎに、お尻洗浄の停止を操作すると、制御部230は、止水電磁弁243と流調弁900を制御して洗浄水の供給を停止する。そして、制御部230は、駆動モータ830を逆回転させて、ノズル本体710およびノズルカバー720を後方へ移動させ、図7や図8に示す元の「収納位置」に戻す。 Next, when the butt cleaning is stopped, the control unit 230 controls the water stop solenoid valve 243 and the flow control valve 900 to stop the supply of cleaning water. Then, the control unit 230 rotates the drive motor 830 in the reverse direction to move the nozzle body 710 and the nozzle cover 720 rearward to return to the original “storage position” shown in FIGS. 7 and 8.
 つぎに、「収納位置」に戻った状態において、制御部230は、止水電磁弁243と流調弁900を制御してお尻洗浄流路714に洗浄水を供給する。そして、お尻洗浄噴出口711から、噴出開口724を介して洗浄水を噴出する。噴出した洗浄水は、抱持部630の内周面で反射して、ノズルカバー本体721の外周面と抱持部630内周面との隙間740を流入する、これにより、主に、ノズルカバー本体721の外周面の汚れを効果的に除去する。 Next, in the state of returning to the “storage position”, the control unit 230 controls the water stop solenoid valve 243 and the flow control valve 900 to supply cleaning water to the bottom cleaning channel 714. Then, washing water is ejected from the buttocks washing ejection port 711 through the ejection opening 724. The jetted cleaning water is reflected by the inner peripheral surface of the holding portion 630 and flows into the gap 740 between the outer peripheral surface of the nozzle cover main body 721 and the inner peripheral surface of the holding portion 630. Thereby, mainly the nozzle cover The dirt on the outer peripheral surface of the main body 721 is effectively removed.
 つぎに、制御部230は、お尻洗浄噴出口711から洗浄水を噴出して所定時間経過後に、止水電磁弁243と流調弁900を制御して洗浄水の供給を停止する。なお、上記の洗浄動作を、「ノズル後洗浄」と称する。 Next, the control unit 230 ejects the washing water from the buttocks washing outlet 711 and, after a predetermined time has elapsed, controls the water stop solenoid valve 243 and the flow control valve 900 to stop the supply of the washing water. The above-described cleaning operation is referred to as “nozzle post-cleaning”.
 以上により、お尻洗浄の動作が完了する。 This completes the ass washing operation.
 以下に、使用者がビデ洗浄を選択した場合について、説明する。 The following describes the case where the user selects bidet cleaning.
 ビデ洗浄を選択した場合、まず、お尻洗浄と同様に、制御部230は駆動モータ830を正回転させてノズル本体710を前方に移動させる。なお、ビデ洗浄の場合は、お尻洗浄位置を越えてさらにノズル本体710を前方に移動させる。 When bidet cleaning is selected, first, similarly to the butt cleaning, the control unit 230 rotates the drive motor 830 in the forward direction to move the nozzle body 710 forward. In the case of bidet cleaning, the nozzle body 710 is further moved forward beyond the buttocks cleaning position.
 このとき、お尻洗浄の場合、図15、図20に示すように、ノズルカバー720に設けたノズルカバーストッパ726は、支持部600の前ストッパ受部623に当接し、ノズルカバー720がこれ以上前方に移動することを規制する。そこで、ビデ洗浄の場合は、さらに駆動モータ830を正回転させて、ノズル本体710を、さらに前方に移動させる。これにより、連結片723の連結突起723aが、前凹陥部717aから外れる。なお、上記動作を可能とするためには、連結突起723aを外すのに要する荷重値よりも、ノズルを前後方向に移動させる駆動モータ830の駆動トルクが大きいことが条件となる。 At this time, as shown in FIGS. 15 and 20, in the case of butt cleaning, the nozzle cover stopper 726 provided on the nozzle cover 720 contacts the front stopper receiving portion 623 of the support portion 600, and the nozzle cover 720 is no more than this. Restrict moving forward. Accordingly, in the case of bidet cleaning, the drive motor 830 is further rotated forward to move the nozzle body 710 further forward. Thereby, the connection protrusion 723a of the connection piece 723 comes off from the front recessed part 717a. In order to enable the above operation, the driving torque of the driving motor 830 that moves the nozzle in the front-rear direction is larger than the load value required to remove the connecting protrusion 723a.
 つぎに、連結突起723aが前凹陥部717aから外れると、ノズル本体710とノズルカバー720は分離された状態となる。このとき、ノズルカバー720は、支持部600の前ストッパ受部623によって移動が規制される。そのため、ノズル本体710だけが、さらに前方に移動し、連結突起723aは後凹陥部717bに、嵌り込む。そして、連結突起723aが後凹陥部717bに完全に嵌入すると、図18に示すように、ビデ洗浄噴出口712がノズルカバー本体721の噴出開口724と対向した状態となる。この時点で、制御部230は、駆動モータ830の駆動を停止する。これにより、ノズル本体710の前方への移動が終了する。この状態が、「ビデ洗浄位置」となる。 Next, when the connection protrusion 723a is disengaged from the front recess 717a, the nozzle body 710 and the nozzle cover 720 are separated. At this time, the movement of the nozzle cover 720 is restricted by the front stopper receiving portion 623 of the support portion 600. Therefore, only the nozzle body 710 moves further forward, and the connection protrusion 723a is fitted into the rear recess 717b. When the connection protrusion 723a is completely fitted into the rear recess 717b, the bidet cleaning jet outlet 712 is opposed to the jet opening 724 of the nozzle cover main body 721 as shown in FIG. At this point, the control unit 230 stops driving the drive motor 830. Thereby, the forward movement of the nozzle body 710 is completed. This state is the “bidet cleaning position”.
 つぎに、「ビデ洗浄位置」にノズル本体710が到達した時点で、制御部230は、止水電磁弁243と流調弁900を制御して、ビデ洗浄流路715に洗浄水を通水して、ビデ洗浄を開始する。そして、ビデ洗浄噴出口712から噴出した洗浄水は、ノズルカバー本体721の噴出開口724に直接接触することなく通過して、上方に噴射される。 Next, when the nozzle body 710 reaches the “bidet cleaning position”, the control unit 230 controls the water stop electromagnetic valve 243 and the flow control valve 900 to pass the cleaning water through the bidet cleaning channel 715. And start bidet cleaning. Then, the washing water ejected from the bidet washing ejection port 712 passes without directly contacting the ejection opening 724 of the nozzle cover main body 721 and is ejected upward.
 このとき、図18に示すように、お尻洗浄噴出口711の上部は、ノズルカバー720のノズルカバー本体721で覆われている状態である。そのため、ビデ洗浄によって生じた汚水が、お尻洗浄噴出口711に直接かかることを防止できる。これにより、お尻洗浄噴出口を清潔に保つことができる。 At this time, as shown in FIG. 18, the upper part of the buttocks cleaning jet outlet 711 is covered with the nozzle cover body 721 of the nozzle cover 720. Therefore, it is possible to prevent the sewage generated by the bidet cleaning from being applied directly to the buttocks cleaning spout 711. Thereby, the buttocks washing spout can be kept clean.
 つぎに、ビデ洗浄の停止を操作すると、制御部230は、止水電磁弁243と流調弁900を制御して洗浄水の供給を停止する。そして、制御部230は、駆動モータ830は逆回転し、ノズル本体710およびノズルカバー720は後方へ移動を開始する。このとき、収納のために後方へ移動する途中過程において、ノズルカバー720のノズルカバーストッパ726は、支持部600の後部に設けた後ストッパ受部624に当接する。 Next, when the bidet cleaning is stopped, the control unit 230 controls the water stop electromagnetic valve 243 and the flow control valve 900 to stop the supply of the cleaning water. Then, in the control unit 230, the drive motor 830 rotates in the reverse direction, and the nozzle body 710 and the nozzle cover 720 start moving backward. At this time, the nozzle cover stopper 726 of the nozzle cover 720 comes into contact with a rear stopper receiving portion 624 provided at the rear portion of the support portion 600 during the process of moving backward for storage.
 そして、ノズルカバーストッパ726が後ストッパ受部624に当接した位置で、制御部230は、駆動モータ830の駆動を停止する。そして、制御部230は、止水電磁弁243と流調弁900を制御してビデ洗浄流路715に洗浄水を供給し、ビデ洗浄噴出口712から噴出させる。ビデ洗浄噴出口712から噴出した洗浄水は、支持部600の抱持部630の内周面で反射して、ノズルカバー本体721の外周面と抱持部630内周面との隙間740を流入する。これにより、主に、ノズルカバー本体721の外周面の汚れを効果的に除去する。 Then, at a position where the nozzle cover stopper 726 contacts the rear stopper receiving portion 624, the control unit 230 stops driving the drive motor 830. Then, the control unit 230 controls the water stop solenoid valve 243 and the flow control valve 900 to supply the cleaning water to the bidet cleaning flow path 715 and eject it from the bidet cleaning jet outlet 712. The washing water ejected from the bidet washing outlet 712 is reflected by the inner peripheral surface of the holding portion 630 of the support portion 600 and flows into the gap 740 between the outer peripheral surface of the nozzle cover body 721 and the inner peripheral surface of the holding portion 630. To do. Thereby, mainly, dirt on the outer peripheral surface of the nozzle cover main body 721 is effectively removed.
 つぎに、制御部230は、ビデ洗浄噴出口712から洗浄水を噴出して所定時間経過後に、止水電磁弁243と流調弁900を制御して洗浄水の供給を停止する。 Next, the control unit 230 ejects the washing water from the bidet washing outlet 712 and, after a predetermined time has elapsed, controls the water stop solenoid valve 243 and the flow control valve 900 to stop the supply of the washing water.
 そして、ノズル洗浄終了後、制御部230は、駆動モータ830を逆回転し、ノズル本体710を、さらに後方に移動させる。このとき、ノズルカバー720に設けたノズルカバーストッパ726は、支持部600の後ストッパ受部624に当接し、ノズルカバー720がこれ以上後方に移動することを規制する。そのため、さらに、ノズル本体710を後方に移動せると、連結片723の連結突起723aが、後凹陥部717bから外れる。なお、上記の動作を可能とするためには、連結突起723aの解除に要する荷重値よりも、ノズルカバー720を前後方向に移動させる駆動モータ830の駆動トルクが大きいことが条件となる。 Then, after the nozzle cleaning is completed, the control unit 230 reversely rotates the drive motor 830 to move the nozzle body 710 further rearward. At this time, the nozzle cover stopper 726 provided on the nozzle cover 720 contacts the rear stopper receiving portion 624 of the support portion 600 and restricts the nozzle cover 720 from moving further rearward. Therefore, when the nozzle body 710 is further moved rearward, the connection protrusion 723a of the connection piece 723 is detached from the rear recess 717b. In order to enable the above-described operation, it is a condition that the driving torque of the driving motor 830 that moves the nozzle cover 720 in the front-rear direction is larger than the load value required to release the connection protrusion 723a.
 つぎに、連結突起723aが後凹陥部717bから外れると、ノズル本体710とノズルカバー720は分離された状態となる。このとき、ノズルカバー720は、支持部600の後ストッパ受部624によって移動を規制される。そのため、ノズル本体710だけが、さらに後方に移動し、連結突起723aは前凹陥部717aに嵌り込む。そして、連結突起723aが前凹陥部717aに完全に嵌入すると、図13に示すように、ノズルカバー本体721の噴出開口724がお尻洗浄噴出口711と対向する状態となる。この時点で、制御部230は、駆動モータ830の回転を停止する。これにより、ノズル本体710の収納動作が終了する。 Next, when the connection protrusion 723a is disengaged from the rear recess 717b, the nozzle body 710 and the nozzle cover 720 are separated. At this time, the movement of the nozzle cover 720 is restricted by the rear stopper receiving portion 624 of the support portion 600. Therefore, only the nozzle body 710 moves further rearward, and the connection protrusion 723a fits into the front recess 717a. When the connecting projection 723a is completely inserted into the front recess 717a, the ejection opening 724 of the nozzle cover body 721 is opposed to the buttocks cleaning ejection port 711 as shown in FIG. At this time, the control unit 230 stops the rotation of the drive motor 830. Thereby, the storing operation of the nozzle body 710 is completed.
 以上により、ビデ洗浄の動作が完了する。 This completes the bidet cleaning operation.
 以下に、衛生洗浄装置の未使用時に、ノズル部700をクリーニングする場合の動作について、説明する。 Hereinafter, the operation when the nozzle unit 700 is cleaned when the sanitary washing apparatus is not used will be described.
 まず、使用者が、操作スイッチ212でノズルクリーニングの操作を設定する。これにより、制御部230は、駆動モータ830を正回転させて、ノズル本体710とノズルカバー720を前方に移動させる。 First, the user sets the nozzle cleaning operation with the operation switch 212. As a result, the control unit 230 rotates the drive motor 830 in the forward direction to move the nozzle body 710 and the nozzle cover 720 forward.
 そして、ノズル本体710が「お尻洗浄位置」に到達すると、制御部230は、駆動モータ830を停止する。さらに、制御部230は、止水電磁弁243と流調弁900を制御して、ノズルクリーニング流路716に洗浄水の通水を開始する。 When the nozzle body 710 reaches the “butt cleaning position”, the control unit 230 stops the drive motor 830. Further, the control unit 230 controls the water stop solenoid valve 243 and the flow control valve 900 to start the flow of cleaning water through the nozzle cleaning flow path 716.
 このとき、ノズルクリーニング噴出口713から噴出した洗浄水は、ノズルカバー720の内部に噴出され、ノズルカバー720の排水口725からノズルカバー720の外部に放出される。これにより、使用者は、排水口725から放出された洗浄水を使用して、ブラシなどでノズル部700とその周辺の清掃を行うことができる。 At this time, the washing water ejected from the nozzle cleaning ejection port 713 is ejected into the nozzle cover 720 and discharged from the drain port 725 of the nozzle cover 720 to the outside of the nozzle cover 720. Thereby, the user can clean the nozzle part 700 and its surroundings with a brush etc. using the washing water discharge | released from the drain outlet 725. FIG.
 つぎに、清掃終了後に、使用者が停止操作を行うことにより、制御部230は、止水電磁弁243と流調弁900を制御して洗浄水の噴出を停止する。そして、制御部230は、駆動モータ830を駆動してノズル本体710を収納位置へ移動させる。 Next, after the cleaning is completed, when the user performs a stop operation, the control unit 230 controls the water stop solenoid valve 243 and the flow control valve 900 to stop the ejection of the wash water. Then, the control unit 230 drives the drive motor 830 to move the nozzle body 710 to the storage position.
 以上により、ノズル部700のクリーニング動作が完了する。 Thus, the cleaning operation of the nozzle unit 700 is completed.
 これらにより、使用者が設定した操作がお尻洗浄、ビデ洗浄およびノズルクリーニング洗浄の動作が行われる。 As a result, the operations set by the user perform the hip cleaning, bidet cleaning, and nozzle cleaning cleaning operations.
 以上のように、本実施の形態によれば、ノズル部700の前方は抱持部630により支持され、後方はスライダ750を介してガイドレール621に支持される。この状態で、可撓ラック810から付与される駆動力が、支持部600の前端と後端との中間に常に加えられる構成としている。そのため、可撓ラック810からスライダ750に付与される駆動力により発生する摩擦抵抗を前後に分散して、摩擦抵抗を小さくできる。これにより、大きな摩擦抵抗によるスライダ750の摺動が不安定になることを抑制して、ノズル部700をスムーズに摺動することができる。その結果、ノズル部700の洗浄位置の位置決め精度を向上できる。 As described above, according to the present embodiment, the front portion of the nozzle portion 700 is supported by the holding portion 630, and the rear portion is supported by the guide rail 621 via the slider 750. In this state, the driving force applied from the flexible rack 810 is always applied between the front end and the rear end of the support portion 600. Therefore, the frictional resistance generated by the driving force applied from the flexible rack 810 to the slider 750 can be dispersed back and forth to reduce the frictional resistance. Thereby, it is possible to suppress the sliding of the slider 750 due to a large frictional resistance and to smoothly slide the nozzle portion 700. As a result, the positioning accuracy of the cleaning position of the nozzle unit 700 can be improved.
 また、本実施の形態によれば、ガイドレール621とラックガイド622は、ノズル装置500の上方に配置し、ノズル部700はスライダ750を介してガイドレール621に懸装された構成を有する。このとき、スライダ750は、ノズル部700の上方に配置される。そのため、スライダ750に一体に結合される可撓ラック810の一端も、ノズル装置500の略最上部(最上部を含む)に配置される。これにより、可撓ラック810のスムーズな駆動に要求される曲率で形成する軌跡を、ノズル装置500の略最上部と略最下部(最下部を含む)との間で形成することが可能となる、その結果、ノズル装置500全体の高さを機能上、必要最小限度の高さにできる。 Further, according to the present embodiment, the guide rail 621 and the rack guide 622 are arranged above the nozzle device 500, and the nozzle unit 700 is suspended from the guide rail 621 via the slider 750. At this time, the slider 750 is disposed above the nozzle unit 700. Therefore, one end of the flexible rack 810 that is integrally coupled to the slider 750 is also disposed at the substantially uppermost portion (including the uppermost portion) of the nozzle device 500. Thereby, a trajectory formed with a curvature required for smooth driving of the flexible rack 810 can be formed between the substantially uppermost portion and the lowermost portion (including the lowermost portion) of the nozzle device 500. As a result, the overall height of the nozzle device 500 can be reduced to the minimum necessary in terms of function.
 また、本実施の形態によれば、ノズル部700は、お尻洗浄噴出口711とビデ洗浄噴出口712とノズルクリーニング噴出口713の3個の噴出口と、それぞれの噴出口に個別に連通するお尻洗浄流路714とビデ洗浄流路715とノズルクリーニング流路716の3本の流路と、流路への洗浄水の供給を切り替える流調弁900とを一体に備えて構成される。そのため、ノズル部700には、1本の接続チューブ612で洗浄水を供給することが可能となる。これにより、ノズル装置500の進退駆動の抵抗となる接続チューブ612を必要最小限度の1本で、スムーズな進退移動が可能になる。その結果、駆動機構に関わる駆動モータ830、ピニオンギア820、可撓ラック810などを小型化して、ノズル装置500全体を小型化および軽量化することができる。 Further, according to the present embodiment, the nozzle unit 700 communicates individually with the three outlets of the butt cleaning outlet 711, the bidet cleaning outlet 712, and the nozzle cleaning outlet 713, and the respective outlets. The three channels of the butt cleaning channel 714, the bidet cleaning channel 715, and the nozzle cleaning channel 716, and the flow control valve 900 that switches the supply of the cleaning water to the channel are integrally provided. Therefore, it is possible to supply cleaning water to the nozzle unit 700 with a single connection tube 612. As a result, it is possible to smoothly move back and forth with one connection tube 612 that serves as resistance for forward / backward drive of the nozzle device 500. As a result, the drive motor 830, the pinion gear 820, the flexible rack 810, and the like related to the drive mechanism can be reduced in size, and the entire nozzle device 500 can be reduced in size and weight.
 また、本実施の形態によれば、ノズル部700は、3個の噴出口と、噴出口に個別に連通する3本の流路を備えたノズル本体710と、ノズル本体710の多くの部分を覆う筒状のノズルカバー720と、ノズル本体710とノズルカバー720を連結する連結部730とを備える。さらに、お尻洗浄噴出口711とビデ洗浄噴出口712から噴出した洗浄水は、ノズルカバー720の噴出開口724を介して外部に噴出する構成を有する。これにより、複数の噴出口を備えたノズル本体710でありながら、1個の共通の噴出開口724を介して洗浄水を噴出できる。その結果、汚れが付着しやすい箇所を少なくして、清潔性が向上する。さらに、ノズル装置500の見栄えも向上し、衛生的で清潔感を維持できる。 In addition, according to the present embodiment, the nozzle unit 700 includes three jet outlets, a nozzle main body 710 having three flow paths individually communicating with the jet outlets, and many portions of the nozzle main body 710. A cylindrical nozzle cover 720 for covering, and a connecting portion 730 for connecting the nozzle body 710 and the nozzle cover 720 are provided. Further, the washing water ejected from the buttocks washing ejection port 711 and the bidet washing ejection port 712 is configured to be ejected to the outside through the ejection opening 724 of the nozzle cover 720. Accordingly, the cleaning water can be ejected through one common ejection opening 724 while the nozzle body 710 is provided with a plurality of ejection ports. As a result, the number of places where dirt easily adheres is reduced, and the cleanliness is improved. Furthermore, the appearance of the nozzle device 500 is improved, and a hygienic and clean feeling can be maintained.
 なお、本実施の形態では、可撓ラックをTPU(熱可塑性ポリウレタン)またはTPEE(ポリエステル系エラストマ)からなるTPE(熱可塑性エラストマ)で成型し、外周面にフッ素樹脂であるPTFE(ポリテトラフルオロエチレン樹脂)をコーティングした構成を例に説明したが、これに限られない。例えば、可撓ラックを、フッ素樹脂を含有した熱可塑性エラストマで成型してもよい。これにより、可撓ラックの摩擦抵抗を低減する効果を得ることができる。 In the present embodiment, the flexible rack is molded with TPE (thermoplastic elastomer) made of TPU (thermoplastic polyurethane) or TPEE (polyester elastomer), and PTFE (polytetrafluoroethylene) which is a fluororesin on the outer peripheral surface. The configuration in which the resin is coated has been described as an example, but is not limited thereto. For example, the flexible rack may be molded with a thermoplastic elastomer containing a fluororesin. Thereby, the effect of reducing the frictional resistance of the flexible rack can be obtained.
 また、本実施の形態では、摺動抵抗を低減するために、スライダの内周面は両側端部のみがガイドレールの上下面と接触するように小さい寸法に形成し、中央部はガイドレールと間隙が生じるように凹陥した断面に形成した例で説明したが、これに限られない。例えば、スライダの内周面か、ガイドレールの上下面のどちらかに、摺動方向に沿って複数のリブを形成してもよい。これにより、スライダとガイドレールとの接触面積を減少させて、摺動抵抗を低減することができる。 Further, in this embodiment, in order to reduce the sliding resistance, the inner peripheral surface of the slider is formed in a small size so that only the end portions on both sides are in contact with the upper and lower surfaces of the guide rail, and the central portion is formed with the guide rail. Although an example in which the cross section is recessed so as to generate a gap has been described, the present invention is not limited to this. For example, a plurality of ribs may be formed along the sliding direction on either the inner peripheral surface of the slider or the upper and lower surfaces of the guide rail. Thereby, the contact area of a slider and a guide rail can be reduced, and sliding resistance can be reduced.
 以上で説明したように、本発明のノズル装置は、噴出口と、噴出口に連通する流路を備えたノズル部と、ノズル部を進退可能に支持する支持部と、ノズル部を進退移動させる駆動部と、を含む。そして、駆動部は、ノズル部に結合された可撓ラックと、可撓ラックを進退移動させるギアと、ギアを駆動するモータと、を備える。支持部は、先端部にノズル部を抱囲して支持する抱持部と、抱持部の後方にノズル部の進退移動を案内するガイドレールと、可撓ラックの進退移動を案内するラックガイドと、を備える。さらに、ノズル部の後端近傍には、ガイドレールに係合して摺動する摺動部を備える。そして、可撓ラックは、摺動部の前部に結合され、可撓ラックを介してノズル部に付与される駆動力は、抱持部の先端と摺動部の後端との中間に常時作用する構成を有してもよい。 As described above, the nozzle device of the present invention has a jet port, a nozzle portion having a flow channel communicating with the jet port, a support portion that supports the nozzle portion so as to advance and retreat, and moves the nozzle portion forward and backward. And a drive unit. The drive unit includes a flexible rack coupled to the nozzle unit, a gear that moves the flexible rack forward and backward, and a motor that drives the gear. The support portion includes a holding portion that surrounds and supports the nozzle portion at the tip portion, a guide rail that guides the forward and backward movement of the nozzle portion behind the holding portion, and a rack guide that guides the forward and backward movement of the flexible rack. And comprising. Furthermore, a sliding part that engages and slides on the guide rail is provided near the rear end of the nozzle part. The flexible rack is coupled to the front portion of the sliding portion, and the driving force applied to the nozzle portion via the flexible rack is always between the front end of the holding portion and the rear end of the sliding portion. You may have the structure which acts.
 これにより、摺動部がガイドレールに沿って摺動する。このとき、ノズル部は前方を抱持部で支持され、後方を摺動部で支持された状態で、それら2個の支持点の中間部に可撓ラックによる駆動力が付与される。そのため、ノズル部のスムーズな摺動と移動軌跡を安定させることができる。その結果、ノズル部の噴出口を適切な洗浄位置に移動させることができる。 This causes the sliding part to slide along the guide rail. At this time, the nozzle portion is supported by the holding portion on the front side and supported by the sliding portion on the rear side, and a driving force by the flexible rack is applied to an intermediate portion between the two support points. Therefore, smooth sliding and movement trajectory of the nozzle part can be stabilized. As a result, the nozzle outlet can be moved to an appropriate cleaning position.
 また、本発明のノズル装置は、ガイドレールとラックガイドが、ノズル部の上方に配置され、ノズル部は摺動部を介してガイドレールに懸装された構成を有してもよい。 Further, the nozzle device of the present invention may have a configuration in which the guide rail and the rack guide are arranged above the nozzle portion, and the nozzle portion is suspended from the guide rail via the sliding portion.
 これにより、摺動部はノズル部の上方に配置され、摺動部に結合される可撓ラックの一端もノズル装置の略最上部に配置することが可能となる。これにより、可撓ラックのスムーズな駆動に要求される曲率で形成する軌跡を、ノズル装置の略最上部と略最下部との間で形成することが可能となる。その結果、ノズル装置全体の高さを機能上必要最小限度の高さで形成できる。 Thus, the sliding portion is disposed above the nozzle portion, and one end of the flexible rack coupled to the sliding portion can be disposed substantially at the uppermost portion of the nozzle device. This makes it possible to form a trajectory formed with a curvature required for smooth driving of the flexible rack between the substantially uppermost part and the substantially lowermost part of the nozzle device. As a result, the height of the entire nozzle device can be formed with the minimum height necessary for the function.
 また、本発明のノズル装置は、ノズル部が、複数の噴出口と、噴出口に個別に連通する複数の流路と、複数の流路への洗浄水の供給を切り替える流調弁と、を一体に備えて構成してもよい。 Further, in the nozzle device of the present invention, the nozzle portion includes a plurality of ejection ports, a plurality of flow channels individually communicating with the ejection ports, and a flow control valve that switches supply of cleaning water to the plurality of flow channels. You may comprise and comprise integrally.
 これにより、ノズル部には1本の接続チューブで洗浄水を供給することが可能となり、ノズル装置の進退駆動の抵抗となる接続チューブを必要最小限度の1本とすることにより、スムーズな進退移動が可能となるとともに、駆動機構に関わるモータ、ギア、可撓ラックなどを小型化することが可能となり、ノズル装置全体を小型および軽量化することができる。 As a result, it becomes possible to supply cleaning water to the nozzle portion with a single connection tube, and by making the connection tube that serves as a resistance for the advance / retreat drive of the nozzle device to one minimum, smooth advance / retreat movement is possible. It is possible to reduce the size of motors, gears, flexible racks and the like related to the drive mechanism, and the overall nozzle device can be reduced in size and weight.
 また、本発明のノズル装置は、ノズル部が、複数の噴出口と、噴出口に個別に連通する複数の流路を備えたノズル本体と、ノズル本体の少なくとも一部を覆うノズルカバーと、ノズル本体とノズルカバーを連結する連結部とを備える。そして、ノズルカバーは噴出開口を有し、ノズル本体の複数の噴出口に噴出開口を対向させるようにノズル本体とノズルカバーは相互に摺動可能な構成とする。さらに、噴出口より噴出した洗浄水は噴出開口を介して外部に噴出する構成としてもよい。 In the nozzle device of the present invention, the nozzle portion includes a plurality of jet nozzles, a nozzle main body provided with a plurality of flow paths individually communicating with the jet nozzle, a nozzle cover that covers at least a part of the nozzle main body, and a nozzle A connecting portion for connecting the main body and the nozzle cover; The nozzle cover has an ejection opening, and the nozzle body and the nozzle cover are configured to be slidable with each other so that the ejection openings are opposed to a plurality of ejection ports of the nozzle body. Further, the cleaning water ejected from the ejection port may be ejected to the outside through the ejection opening.
 これにより、複数の噴出口を有するノズル本体の場合でも、噴出開口を噴出口より少なくできる。その結果、汚れの付着しやすい箇所が少なくなるので、清潔性が向上する。また、見栄えもすっきりとし、衛生的で清潔感を維持できる。 Thereby, even in the case of a nozzle body having a plurality of jet nozzles, the jet opening can be made smaller than the jet nozzle. As a result, the number of places where dirt easily adheres is reduced, and the cleanliness is improved. It also has a clean appearance and is hygienic and clean.
