しかしながら、前記従来の構成では、衛生洗浄装置の局部洗浄ノズルは、ノズル本体2の先端部に設けたノズル孔2aから洗浄水を噴出する前では開放状態になるので、外部からの汚物等が浸入しやすく、洗浄水の衛生面での心配が生じる。ここで、ブラシ等により汚れを取り除こうとしても、ノズル本体2内部まで充分に清掃することは困難であり、また、ノズル全体に洗剤や高温水をかけて汚れを取り除く方法も考えられるが、樹脂製のノズルに洗剤や高温水をかけることは不適切であり、結果、充分な清掃を行うことは困難であるという課題を有していた。   However, in the conventional configuration, the local cleaning nozzle of the sanitary cleaning device is in an open state before the cleaning water is ejected from the nozzle hole 2 a provided at the tip of the nozzle body 2, so that foreign matters enter the outside. It is easy to clean and raises concerns about the hygiene of cleaning water. Here, even if it is attempted to remove dirt with a brush or the like, it is difficult to sufficiently clean the inside of the nozzle body 2, and a method of removing dirt by applying detergent or high-temperature water to the entire nozzle is conceivable. It was inappropriate to apply detergent or high-temperature water to the nozzle made of the product, and as a result, it was difficult to perform sufficient cleaning.

本発明は、前記従来からの課題を解決するもので、ノズル孔2aに開閉部を設けることにより、ノズル本体2内部への汚物の侵入を防ぎ清潔な洗浄水を噴出する局部洗浄ノズルを提供することを目的とする。   The present invention solves the above-described conventional problems, and provides a local cleaning nozzle that prevents the entry of filth into the nozzle body 2 and ejects clean cleaning water by providing an opening / closing portion in the nozzle hole 2a. For the purpose.

前記従来の課題を解決するために、本発明の局部洗浄ノズルは、ノズル本体先端内部に、洗浄水を噴出するノズル本体孔に開閉部材を内装したものである。   In order to solve the above-described conventional problems, a local cleaning nozzle according to the present invention has an opening / closing member provided in a nozzle body hole for ejecting cleaning water inside a nozzle body tip.

これによって、局部を洗浄する寸前までノズル孔は閉止され、汚物が浸入しないため、洗浄水の衛生が保たれ、衛生面を向上した衛生洗浄装置の局部洗浄ノズルとなる。   As a result, the nozzle hole is closed to the point immediately before the local portion is cleaned, and the filth does not enter, so that the hygiene of the cleaning water is maintained and the local cleaning nozzle of the sanitary cleaning device is improved.

以上のように本発明の局部洗浄ノズルによると、衛生的な洗浄水を噴出することができるとともに、ノズル内部を清潔に維持することができる。   As described above, according to the local cleaning nozzle of the present invention, hygienic cleaning water can be ejected and the inside of the nozzle can be kept clean.

第1の発明は、人体局部に向けて洗浄水を噴出するノズル孔を設けたノズル本体と、前記ノズル本体の内部に、ノズル孔を開閉するように移動する内設部材と、前記内接部材に接触したバネ部材を備え、前記内接部材は洗浄水の水圧により前記ノズル孔を開放するように移動し、前記ばね部材により前記ノズル孔を閉止するように移動し、前記内設部材は、前記ノズル孔に導通する流路部と、前記ノズル孔を閉鎖する閉鎖部を形成し、前記流路部は前記ノズル本体の軸方向から洗浄水の噴出方向へ曲折するように形成し、前記流路部の長さが2mm以上とすることにより、外部からの汚物浸入防止することができ、しかも噴出した洗浄水の噴出状態や噴出方向を安定させることができる。 According to a first aspect of the present invention, there is provided a nozzle main body provided with a nozzle hole for jetting cleaning water toward a local body part, an internal member that moves inside the nozzle main body so as to open and close the nozzle hole, and the inscribed member The inscribed member moves so as to open the nozzle hole by the water pressure of washing water, and moves so as to close the nozzle hole by the spring member . A flow path portion that is connected to the nozzle hole and a closed portion that closes the nozzle hole are formed, and the flow path portion is formed so as to bend from the axial direction of the nozzle body to the direction of jetting of the washing water, by the length of the road section is not less than 2 mm, it is possible to contaminants entering prevention from outside, moreover the ejection state and ejection direction of the washing water jetted Ru can be stabilized.

第2の発明は、特に、第1の発明の内設部材をノズル本体のノズル孔近傍に設けたことにより、内設部材の大きさを小さくすることができ、かつ、容易に作製することができる。 In the second invention, in particular, since the internal member of the first invention is provided in the vicinity of the nozzle hole of the nozzle body, the size of the internal member can be reduced and can be easily manufactured. kill at.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、本実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(実施の形態1)
図1〜5は本発明の第1の実施の形態における人体の局部洗浄中(a)と洗浄前(b)の洗浄ノズル先端の断面図を示すものである。
(Embodiment 1)
1 to 5 show sectional views of the tip of the cleaning nozzle during local cleaning (a) and before cleaning (b) of the human body in the first embodiment of the present invention.

図1において、内設部材1は、ノズル本体2のノズル孔2aを開閉するものであり、バネ部材3と関連して開閉弁を構成している。   In FIG. 1, the internal member 1 opens and closes the nozzle hole 2 a of the nozzle body 2 and constitutes an open / close valve in association with the spring member 3.

以上のように構成された局部洗浄ノズルについて、以下その動作、作用を説明する。   The operation and action of the local cleaning nozzle configured as described above will be described below.

まず、人体の局部洗浄中(a)において内設部材1は、洗浄水の水圧によってノズル本体2の先端へと軸方向に移動する。移動位置は、ノズル本体2の内側形状とバネ部材3の設定荷重で決まり、内設部材1の流路部1aとノズル本体2のノズル孔2aが一致し、洗浄水が噴出するように設定されている。   First, during the local cleaning of the human body (a), the internal member 1 moves in the axial direction toward the tip of the nozzle body 2 by the water pressure of the cleaning water. The moving position is determined by the inner shape of the nozzle body 2 and the set load of the spring member 3, and is set so that the flow path portion 1a of the inner member 1 and the nozzle hole 2a of the nozzle body 2 are coincident with each other and the washing water is ejected. ing.

また、ノズル本体2が衛生洗浄装置本体(図示せず)から繰り出して洗浄位置に移動するまで、ノズル本体2のノズル孔2aが閉止されているため、ノズル本体1が移動時にノズル本体孔2aから洗浄水が吹き上げて、おしりに接触し不快感を与えることに対しても防止効果がある。   Further, since the nozzle hole 2a of the nozzle body 2 is closed until the nozzle body 2 is fed out from the sanitary washing device body (not shown) and moved to the cleaning position, the nozzle body 1 moves from the nozzle body hole 2a when moving. There is also an effect of preventing washing water from blowing up and coming into contact with the buttocks and causing discomfort.

次に人体局部洗浄前(b)の動作、作用について説明する。洗浄前は、ノズル本体2の内部の洗浄水の水圧が低く、内設部材1は、バネ部材3によってノズル本体2の後端部に移動し、閉鎖部1bとノズル孔2aが一致する位置まで移動し、完全にノズル孔2aを閉止する。   Next, the operation and action before (b) human body local cleaning will be described. Before cleaning, the water pressure of the cleaning water inside the nozzle body 2 is low, and the internal member 1 is moved to the rear end portion of the nozzle body 2 by the spring member 3 until the closing portion 1b and the nozzle hole 2a coincide with each other. The nozzle hole 2a is completely closed.

従って、人体の洗浄中以外つまりノズル孔2aから洗浄水が噴出していない時はノズル本体2のノズル孔2aが閉止されているため、汚物等がノズル本体2内に浸入することがない。よって常に清潔な洗浄水を得ることができる。このための構成がノズル本体2のノズル孔2aの近傍部だけで完結したシンプルな構成で作成することができる。また、コンパクトな内設部材1で作成することができ、形状も簡単であり、樹脂やゴム等の生産性が良く安価な材料で作成することができる。   Accordingly, when the human body is not being cleaned, that is, when the cleaning water is not ejected from the nozzle hole 2a, the nozzle hole 2a of the nozzle body 2 is closed, so that dirt or the like does not enter the nozzle body 2. Therefore, clean washing water can always be obtained. The configuration for this purpose can be created with a simple configuration completed only in the vicinity of the nozzle hole 2a of the nozzle body 2. Moreover, it can produce with the compact internal member 1, and the shape is simple, and it can produce with good productivity, such as resin and rubber | gum, and cheap.

また、内設部材1は図2に示すように、流路1aの近傍にシール部材4を設けると更に気密性が向上し、人体の汚物がノズル本体2内に浸入しにくくなる効果が得られる。   Further, as shown in FIG. 2, when the sealing member 4 is provided in the vicinity of the flow path 1 a, the inner member 1 is further improved in airtightness, and an effect of preventing human body dirt from entering the nozzle body 2 is obtained. .

また、内設部材1は図3に示すように、内設部材孔1aの本体円周方向にシール部材4を設けるとノズル本体2の内径との嵌合が一定になるため動作荷重のバラツキが安定し、内設部材1の移動動作の信頼性が向上できる。   Further, as shown in FIG. 3, the inner member 1 is provided with a seal member 4 in the circumferential direction of the main body of the inner member hole 1a, so that the fitting with the inner diameter of the nozzle main body 2 becomes constant, so that there is a variation in the operating load. It is stable and the reliability of the movement operation of the internal member 1 can be improved.

また、図4に示すように、内設部材1を回転させる回転軸5を設け、回転動作によりノズル本体2のノズル孔2aを開閉する方式の内設部材1を用いても同様に実施することができる。   Further, as shown in FIG. 4, the same operation can be performed by using the internal member 1 of a system in which a rotating shaft 5 for rotating the internal member 1 is provided and the nozzle hole 2 a of the nozzle body 2 is opened and closed by a rotating operation. Can do.

また、図5に示すように、内設部材の駆動による方法ではなく、弁体である逆止弁部材6をノズル本体2の洗浄噴出孔部に設けることにより、簡単な構成で配置でき、外部からの汚物に対しても浸入防止効果が得られ、材質についても柔軟なゴム材や洗浄水の温度に反応する形状記憶合金等でも同じ効果が得られる。   Further, as shown in FIG. 5, the check valve member 6 which is a valve body is not a method by driving the internal member, but can be arranged with a simple configuration by providing the cleaning jet hole portion of the nozzle body 2, and externally. The effect of preventing intrusion can be obtained even from sewage, and the same effect can be obtained by using a flexible rubber material or a shape memory alloy that reacts to the temperature of the washing water.

(実施の形態2)
図6は本発明の第2の実施の形態における人体の局部洗浄中(a)と洗浄前(b)の洗浄ノズル先端の断面図を示すものである。
(Embodiment 2)
FIG. 6 is a cross-sectional view of the front end of the cleaning nozzle during local cleaning (a) and before cleaning (b) of the human body in the second embodiment of the present invention.

図6において、ノズル本体2は、金属の深絞り加工よって形成されたものであり、内設部材1は、ノズル本体2のノズル孔2aの開閉と洗浄水の流路効果とを同時に満たすための流路を備えたものであり、バネ部材3と関連して開閉弁を構成している。   In FIG. 6, the nozzle body 2 is formed by metal deep drawing, and the internal member 1 is used to simultaneously satisfy the opening and closing of the nozzle hole 2 a of the nozzle body 2 and the flow path effect of the washing water. A flow path is provided, and an open / close valve is configured in association with the spring member 3.

以上のように構成された局部洗浄ノズルについて、以下その動作、作用を説明する。   The operation and action of the local cleaning nozzle configured as described above will be described below.

まず、人体の局部洗浄中(a)において内設部材1は、洗浄水の水圧によってノズル本体2の先端へと軸方向に移動する。移動位置は、ノズル本体2の内側形状とバネ部材3の設定荷重で決まり、流路部1aの出口とノズル本体2のノズル孔2aが一致し、洗浄水が噴出するように設定されている。そしてノズル本体2は、金属の深絞り加工によって形成されているため、肉厚は0.3mm程度と薄く、そのため、人体の局部を洗浄するための洗浄水の噴出流の状態が不安定となる。これはノズル孔2aの流路長が0.3mmであるため、洗浄水の噴出方向が決まらず水流の影響(例えば、流量の微小な変化や気泡の混入)により都度噴出方向が変化するためである。ここで正常水の噴出状態を安定させる、つまり人体局部の洗浄特性を向上するために内部材1の流路1aの長さを2mm以上確保することにより洗浄水流の方向性が定まり整流化され、ノズル孔2aに到達する時には安定した流れとなる。よって、ノズル孔2aから噴出した洗浄水は、噴出状態や噴出方向が安定し、特に複数のノズル孔2aを備え、複数の洗浄水を噴出させる必要性があるビデ洗浄に効果的である。すなわち、図1においてノズル孔2aは1個を図示したが、例えばビデ洗浄ノズルとして、ノズル孔を複数設けても同じ効果を得ることができる。 First, during the local cleaning of the human body (a), the internal member 1 moves in the axial direction toward the tip of the nozzle body 2 by the water pressure of the cleaning water. The moving position is determined by the inner shape of the nozzle body 2 and the set load of the spring member 3, and is set so that the outlet of the flow path portion 1a and the nozzle hole 2a of the nozzle body 2 are coincident and the washing water is ejected. And since the nozzle body 2 is formed by metal deep drawing, the thickness is as thin as about 0.3 mm, so that the state of the flow of washing water for washing the local part of the human body becomes unstable. . This is because the flow path length of the nozzle hole 2a is 0.3 mm, and the jet direction of the washing water is not determined, and the jet direction changes each time due to the influence of the water flow (for example, minute change in flow rate or mixing of bubbles). is there. Here stabilize the ejection state of normal water, i.e. the direction of the cleaning water flow is rectified Sadamari by securing the length of the inner contact member 1 of the flow path 1a least 2mm in order to improve the cleaning properties of the human private When the nozzle hole 2a is reached, a stable flow is obtained. Therefore, the washing water ejected from the nozzle hole 2a has a stable ejection state and ejection direction, and is particularly effective for bidet washing that includes the plurality of nozzle holes 2a and needs to eject a plurality of washing water. That is, although one nozzle hole 2a is illustrated in FIG. 1, the same effect can be obtained even if a plurality of nozzle holes are provided as, for example, a bidet cleaning nozzle.

以上のように本発明にかかる局部洗浄ノズルは非使用時のノズル内への汚物の侵入を防止することができるため、特に衛生面での注意が必要な衛生洗浄装置の洗浄ノズルに利用可能であるとともに、他のノズル装置にも利用可能である。   As described above, since the local cleaning nozzle according to the present invention can prevent the entry of filth into the nozzle when not in use, it can be used as a cleaning nozzle for a sanitary cleaning device that requires special hygiene. In addition, it can be used for other nozzle devices.
