Description

本発明は、家庭用排水管内を回転しながら進み、その内部を噴射水によって洗浄することのできる排水管内部洗浄ノズルに関するものである。 TECHNICAL FIELD The present invention relates to a drain pipe internal cleaning nozzle that can be rotated while rotating inside a household drain pipe and that can be cleaned with spray water.

従来、家庭の排水管の内部を洗浄するための手段として、ホースの先端に、８個の噴射口を設けたノズルを取付け、その噴射口から噴射される高圧水の推進力で排水管内を前進移動すると共にその内部を洗浄するようにしたものがある。   Conventionally, as a means for cleaning the interior of a household drainage pipe, a nozzle provided with eight injection ports is attached to the tip of the hose, and the inside of the drainage pipe is advanced by the propulsive force of high-pressure water injected from the injection port. There is something that moves and cleans the inside.

また主軸に回転自在に嵌合したローターに、２つの噴出口を対称位置に設け、噴出口から噴出される高圧水により、ローターに回転力と推進力を与え、ローターを回転させながら前進移動させるものも知られている。   In addition, the rotor that is rotatably fitted to the main shaft is provided with two jet outlets at symmetrical positions, and the high pressure water jetted from the jet outlet gives the rotor a rotational force and a propulsive force to move forward while rotating the rotor. Things are also known.

しかし、前者従来技術においては、噴射口から供給される噴射圧水が当たる部分は洗浄することができるものの、その他の部分には汚れが残存するといった問題がある。   However, in the former prior art, there is a problem that although the portion that is hit by the injection pressure water supplied from the injection port can be washed, the other portions remain dirty.

また、従来技術にあっては、排水管内の多くの部分に噴射水を当てるために多数（８個）の噴射口を設けているため、各噴射口から供給される噴射水の圧力が必ずしも十分でなく、よって、噴射水が当たる部分でも汚れが残る場合がある。   Moreover, in the prior art, since many (eight) injection ports are provided in order to apply the injection water to many portions in the drain pipe, the pressure of the injection water supplied from each injection port is not always sufficient. Therefore, dirt may remain even in the portion where the spray water hits.

また後者の従来技術においては、回転するローターの回転速度が速くなり過ぎると、ローターと主軸の金属同士のいわゆる食い付きが発生して円滑な回転が持続せず、その結果、洗浄効果が低下してしまう。 In the latter prior art, the rotational speed of the rotating rotor is too faster, without lasting smooth rotation so-called bite between metals of the rotor and the main shaft occurs, resulting cleaning effect decreases Resulting in.

本発明はこうした問題に鑑み創案されたもので、家庭用排水管の内部の汚れを確実に洗浄することのできる洗浄ノズルを提供することを課題とする。 The present invention has been devised in view of these problems, and an object of the present invention is to provide a cleaning nozzle that can reliably clean dirt inside a domestic drain pipe.

At the same time, it is drilled from the space recess 31 at an inclination angle β larger than the acute inclination angle α , and gives a rotational force in the opposite direction to the rotor 30 to suppress the rotational force of the rotor 30 in the one direction. tare the sub injection passage 33 provided Keru.

請求項２に記載の発明は、家庭用排水管１の中を回転しながら前進し、高圧噴射水で前記排水管１の内部を洗浄する洗浄ノズルであって、通水路２１を有する筒状で、後半部がホース２に接続され、前半部の周壁に前記通水路２１に連通する孔部２２を穿設した主軸２０と、前記主軸２０の前半部に回転自在に嵌合し、内周面の中央部分に前記孔部２２を介して前記通水路２１に連通する空間凹部３１を有するローター３０と、前記主軸２０の前半部に着脱自在に組付き、前記主軸２０の通水路２１を塞ぐストッパー４０とからなるものである。 The invention according to claim 2 is a cleaning nozzle that advances while rotating in the household drain pipe 1 and cleans the inside of the drain pipe 1 with high-pressure jet water, and has a cylindrical shape having a water passage 21. The rear half is connected to the hose 2, the main shaft 20 having a hole 22 communicating with the water passage 21 in the peripheral wall of the front half, and the front half of the main shaft 20 are rotatably fitted to the inner peripheral surface. A rotor 30 having a space concave portion 31 communicating with the water passage 21 through the hole 22 at the central portion of the main shaft 20 and a front half of the main shaft 20 are detachably assembled, and a stopper that blocks the water passage 21 of the main shaft 20. 40.

そして、前記ローター３０に、前記空間凹部３１から斜め後方に鋭角な傾斜角度αで穿設され、該ローター３０に一方向への回転力と推進力を与える主噴射通路３２を一つまたは複数設けると共に、前記空間凹部３１から前記鋭角な傾斜角度αより大きな傾斜角度βで穿設され、前記ローター３０に反対方向への回転力を与え、該ローター３０の前記一方向への回転力を抑制する副噴射通路３３を設ける。また、前記ローター３０とストッパー４０との間にスペーサー５０を設け、前記ストッパー４０の先端部に、前記ローター３０より小径で球形のガイド部４１を設ける。なお、スペーサー５０は、四フッ化エチレン樹脂が好ましい。 The rotor 30 is provided with one or a plurality of main injection passages 32 which are perforated with an acute inclination angle α obliquely rearward from the space recess 31 and give the rotor 30 rotational force and propulsive force in one direction. At the same time, it is drilled from the space recess 31 at an inclination angle β larger than the acute inclination angle α , and gives a rotational force in the opposite direction to the rotor 30 to suppress the rotational force of the rotor 30 in the one direction. A sub-injection passage 33 is provided. In addition, a spacer 50 is provided between the rotor 30 and the stopper 40, and a spherical guide portion 41 having a smaller diameter than the rotor 30 is provided at the tip of the stopper 40. The spacer 50 is preferably a tetrafluoroethylene resin.

請求項３に記載の発明は、請求項１または２に記載の発明において、ストッパー４０のガイド部４１に、曲折した排水管１内の通過を容易にすべく、案内部材６０を装着してなるものである。   The invention according to claim 3 is the invention according to claim 1 or 2, wherein a guide member 60 is attached to the guide portion 41 of the stopper 40 so as to facilitate passage through the bent drainage pipe 1. Is.

請求項１に記載の発明は、主軸２０とローター３０とストッパー４０とからなり、ローター３０に、その空間凹部３１から斜め後方に鋭角な傾斜角度αで、当該ローター３０に一方向への回転力と推進力を与える主噴射通路３２を一つまたは複数設けると共に、鋭角な傾斜角度αより大きな傾斜角度βで、前記ローター３０の一方向への回転力を抑制する副噴射通路３３を設けたので、排水管１内部の汚れを確実に除去することができる。   The invention according to claim 1 comprises the main shaft 20, the rotor 30, and the stopper 40, and the rotor 30 has a rotational force in one direction on the rotor 30 at an acute inclination angle α obliquely rearward from the space recess 31. In addition, one or a plurality of main injection passages 32 for providing a propulsive force are provided, and a sub injection passage 33 for suppressing the rotational force in one direction of the rotor 30 at an inclination angle β larger than the acute inclination angle α is provided. The dirt inside the drain pipe 1 can be reliably removed.

すなわち、主噴射通路３２から噴射される高圧噴射水の働きによって、ローター３０は回転しながら前進するので、当該主噴射通路３２および副噴射通路３３の両方から噴射される高圧噴射水は、排水管１内部の全面に衝突する。従って、従来技術のように回転しないで単に前進するのとは異なり、全ての汚れを確実に取り除くことができる。   That is, the rotor 30 advances while rotating by the action of the high-pressure jet water jetted from the main jet passage 32, so that the high-pressure jet water jetted from both the main jet passage 32 and the sub-injection passage 33 is drained from the drain pipe. 1 Collides with the entire interior surface. Therefore, unlike the case of simply moving forward without rotating as in the prior art, all dirt can be reliably removed.

また、主噴射通路３２から噴射される高圧噴射水によってローター３０は一方向に回転するが、この回転力を何ら抑制しないと回転速度が速くなり過ぎてローター３０と主軸２０等の金属同士のいわゆる食い付きが発生して円滑な回転が持続せず、その結果、洗浄効果が低下してしまう。本発明では、副噴射通路３３によって、ローター３０の回転力を抑制するので、こうした問題を未然に防止し、汚れを長時間連続して除去することができる。 Further, the rotor 30 rotates in one direction by the high-pressure jet water injected from the main injection passage 32. However, if this rotational force is not suppressed at all, the rotation speed becomes too high and the rotor 30 and the main shaft 20 and other metals are so-called. Biting occurs and smooth rotation does not continue, and as a result, the cleaning effect decreases. In the present invention, the rotational force of the rotor 30 is suppressed by the sub-injection passage 33, so that such a problem can be prevented and the dirt can be removed continuously for a long time.

請求項２に記載の発明は、請求項１に記載の発明と動揺に、排水管１内部の汚れを確実に除去することができると共に、ローター３０とストッパー４０との間にスペーサー５０を設けているので、ローター３０の回転をより円滑なものとすることができる。これにより、排水管内部の汚れをさらに効果的に取り除くことができる。   According to the second aspect of the invention, in addition to the fluctuation of the invention of the first aspect, dirt inside the drain pipe 1 can be surely removed, and a spacer 50 is provided between the rotor 30 and the stopper 40. Therefore, the rotation of the rotor 30 can be made smoother. Thereby, the dirt inside the drain pipe can be more effectively removed.

また、ストッパー４０の先端部に、ローター３０より小径でかつ球形のガイド部４１を設けているので、このガイド部４１のはたらきによってローター３０が排水管１の内部を円滑に前進することができる。よって、排水管１内部の汚れをさらに良好に除去することができる。   Further, since the guide portion 41 having a smaller diameter than the rotor 30 is provided at the distal end portion of the stopper 40, the rotor 30 can smoothly advance inside the drain pipe 1 by the operation of the guide portion 41. Therefore, the dirt inside the drain pipe 1 can be removed more satisfactorily.

請求項３に記載の発明は、ストッパー４０のガイド部４１に、曲折した排水管１内の通過を容易にすべく、案内部材６０を装着しているので、排水管１のコーナー部より奥に至るまで、汚れを良好に取り除くことができる。   In the third aspect of the present invention, the guide member 60 is attached to the guide portion 41 of the stopper 40 so as to facilitate passage through the bent drainage pipe 1. The dirt can be removed well.

本発明に係る家庭用排水管内部洗浄ノズル１０の第一実施形態を、図１乃至図４に示す。これは、家庭のディスポーザー（生ゴミ粉砕器）を備えた台所における排水管１の中を回転しながら前進し、高圧噴射水で排水管１の内部に堆積した卵の殻や油脂類などの汚物を洗浄する洗浄ノズルであり、主軸２０、ローター３０およびストッパー４０で構成される。 1 to 4 show a first embodiment of a domestic drain pipe internal cleaning nozzle 10 according to the present invention. This is a sewage such as egg shells and oils and fats that move forward in the drain pipe 1 in a kitchen equipped with a home disposer (garbage grinder) and accumulate in the drain pipe 1 with high-pressure jet water. This is a cleaning nozzle that cleans the main shaft 20, the rotor 30, and the stopper 40.

主軸２０は、その長手方向の中心部にわたって通水路２１を有する筒状で、後半部が、可撓性高圧ホース２に接続される。また、前半部の周壁に通水路２１に連通する孔部２２を対向して二つ穿設している。なお、主軸２０の中間部にはフランジ部２３を設けている。   The main shaft 20 has a cylindrical shape having a water passage 21 over the center in the longitudinal direction, and the latter half is connected to the flexible high-pressure hose 2. Further, two holes 22 communicating with the water passage 21 are formed in the front wall of the front half so as to face each other. A flange portion 23 is provided in the middle portion of the main shaft 20.

ステンレス鋼，真ちゅう又は四フッ化エチレン樹脂のローター３０は、主軸２０の前半部に回転自在に嵌合し、内周面の中央部分に孔部２２を介して通水路２１に連通する空間凹部３１を有する。また、ストッパー４０は、主軸２０の前半部に着脱自在に螺合組付きする無垢状であり、主軸２０の通水路２１を塞ぐ。   A rotor 30 made of stainless steel, brass or ethylene tetrafluoride resin is rotatably fitted in the front half of the main shaft 20 and communicates with the water passage 21 through the hole 22 in the central portion of the inner peripheral surface. Have The stopper 40 is a solid shape that is detachably screwed to the front half of the main shaft 20 and closes the water passage 21 of the main shaft 20.

そして、ローター３０に、その空間凹部３１から斜め後方に鋭角な傾斜角度α（ここでは、５５°〜６０°）で、当該ローター３０に反時計回り方向への回転力と前方への推進力を与える主噴射通路３２を対向して二つ設けている。また、空間凹部３１から、鋭角な傾斜角度αより大きな傾斜角度β（９０°）で、ローター３０に時計回り方向への回転力を与え、反時計回り方向への回転力を抑制する副噴射通路３３を対向して二つ設けている。副噴射通路３３の出口には、高圧噴射水の噴射方向を考慮し、その表面が真円となるようにザグリ３４を形成している。   Then, the rotor 30 is given a rotational force in the counterclockwise direction and a forward propulsive force to the rotor 30 at an acute inclination angle α (here, 55 ° to 60 °) obliquely rearward from the space recess 31. Two main injection passages 32 are provided opposite to each other. Further, the sub-injection passage that applies a rotational force in the clockwise direction to the rotor 30 at a tilt angle β (90 °) larger than the acute tilt angle α from the space recess 31 and suppresses the counterclockwise rotational force. Two 33 are provided facing each other. A counterbore 34 is formed at the outlet of the sub-injection passage 33 in consideration of the injection direction of the high-pressure injection water so that the surface thereof is a perfect circle.

なお、本実施形態では、図２に示すように、ローター３０に反時計回り方向への回転力を与えるために、主噴射通路３２を、空間凹部３１の左右端部から中心線Ｌに対して垂直方向に向けて形成している。また、ローター３０に時計回り方向への回転力を与えるために（反時計回り方向への回転力を抑えるために）、副噴射通路３３を、空間凹部３１の左右周端部から同じく中心線Ｌから垂直方向に向けて形成している。   In the present embodiment, as shown in FIG. 2, in order to give the rotor 30 a rotational force in the counterclockwise direction, the main injection passage 32 is made from the left and right end portions of the space recess 31 to the center line L. It is formed in the vertical direction. Further, in order to apply a rotational force in the clockwise direction to the rotor 30 (in order to suppress a rotational force in the counterclockwise direction), the sub-injection passage 33 is also connected to the center line L from the left and right peripheral ends of the space recess 31. It is formed from the vertical direction.

さらに、ローター３０とストッパー４０との間に四フッ化エチレン樹脂のスペーサー５０を設けている。また、ストッパー４０の先端部に、ローター３０より小径で球形のガイド部４１を設けている。   Furthermore, a tetrafluoroethylene resin spacer 50 is provided between the rotor 30 and the stopper 40. A spherical guide portion 41 having a smaller diameter than the rotor 30 is provided at the tip of the stopper 40.

本実施形態における排水管洗浄ノズル１０は、ローター３０に、主噴射通路３２と副噴射通路３３を設けているので、排水管１内部の汚れを確実に除去することができる。すなわち、主噴射通路３２から噴射される高圧噴射水の働きによって、ローター３０は回転しながら前進するので、当該主噴射通路３２および副噴射通路３３の両方から噴射される高圧噴射水は、排水管１内部の全面に衝突する。従って、全ての汚れが確実に除去される。   Since the drain pipe cleaning nozzle 10 in the present embodiment is provided with the main injection passage 32 and the sub injection passage 33 in the rotor 30, dirt inside the drain pipe 1 can be reliably removed. That is, the rotor 30 advances while rotating by the action of the high-pressure jet water jetted from the main jet passage 32, so that the high-pressure jet water jetted from both the main jet passage 32 and the sub-injection passage 33 is drained from the drain pipe. 1 Collides with the entire interior surface. Therefore, all dirt is reliably removed.

また、主噴射通路３２から噴射される高圧噴射水によってローター３０は反時計回り方向に回転するが、この回転力を、副噴射通路３３によって抑制するので、ローター３０と主軸２０の食い付きが未然に防止され、汚れを長時間連続して除去することができる。   Further, the rotor 30 is rotated counterclockwise by the high-pressure jet water injected from the main injection passage 32, but this rotational force is suppressed by the sub-injection passage 33, so that the rotor 30 and the main shaft 20 are not caught. Thus, dirt can be removed continuously for a long time.

さらに、ローター３０とストッパー４０との間に四フッ化エチレン樹脂のスペーサー５０を設けているので、ローター３０の回転をより円滑なものとすることができ、排水管内部の汚れをさらに効果的に取り除くことが可能となっている。なお、ローター３０とスペーサー５０は、消耗後、主軸２０から簡単に取り外して交換することができる。   Furthermore, since the tetrafluoroethylene resin spacer 50 is provided between the rotor 30 and the stopper 40, the rotation of the rotor 30 can be made smoother, and dirt inside the drainage pipe can be more effectively removed. It can be removed. The rotor 30 and the spacer 50 can be easily removed from the main shaft 20 and replaced after the wear.

また、ストッパー４０の先端部に、ローター３０より小径でかつ球形のガイド部４１を設けているので、このガイド部４１が、ローター３０を、例えば、直角に曲折した排水管１内部の奥深くまで円滑に案内する。従って、排水管１内部の汚れをさらに良好に除去することができる。   Since the stopper 40 has a spherical guide portion 41 having a diameter smaller than that of the rotor 30, the guide portion 41 can smoothly move the rotor 30 deep inside the drain pipe 1 bent at a right angle, for example. To guide. Therefore, the dirt inside the drain pipe 1 can be removed more satisfactorily.

なお、本実施形態では、図４に示すように、ストッパー４０のガイド部４１に、ジグザグに曲折した排水管１内の通過を容易にすべく、複数の案内部材６０を直列状に装着している。この複数の案内部材６０は、湾曲状に９０°に折れ曲がる。これによって、排水管１の９０度のコーナー部より先の奥に至るまで、汚れを良好に取り除くことができる。   In the present embodiment, as shown in FIG. 4, a plurality of guide members 60 are attached in series to the guide portion 41 of the stopper 40 to facilitate passage through the drain pipe 1 bent in a zigzag manner. Yes. The plurality of guide members 60 are bent at 90 ° in a curved shape. As a result, the dirt can be satisfactorily removed from the corner of the drain pipe 1 beyond the 90-degree corner.

本発明に係る家庭用排水管内部洗浄ノズル１０の第二実施形態を、図５乃至図７に示す。この洗浄ノズル１０は、主噴射通路３２を斜め後方に鋭角な傾斜角度α（３０°）で形成すると共に、副噴射通路３３をそれより大きな傾斜角度β（４５°）で形成している。また、主噴射通路３２の口径を、副噴射通路３３のそれよりやや大きく設定している。これにより、第一実施形態と同様に、ローター３０の回転を適度に抑制して当該ローター３０と主軸２０との食い付きを防止し、排水管１の内部の汚れを効果的に除去することができる。 5 to 7 show a second embodiment of a household drain pipe internal cleaning nozzle 10 according to the present invention. In the cleaning nozzle 10, the main injection passage 32 is formed obliquely rearward with an acute inclination angle α (30 °), and the sub injection passage 33 is formed with a larger inclination angle β (45 °). Further, the diameter of the main injection passage 32 is set slightly larger than that of the sub injection passage 33. Thereby, like 1st embodiment, rotation of the rotor 30 is moderately suppressed, the biting with the said rotor 30 and the main axis | shaft 20 is prevented, and the stain | pollution | contamination inside the drainage pipe 1 can be removed effectively. it can.

なお、上記二つの本実施形態においては、主噴射通路３２および副噴射通路３３をそれぞれ二つずつ設けているが、これによって、各通路からの高圧噴射水を強力なものとすることができ、排水管内部の汚れを、より効果的に除去することができる。ちなみに、各通路の数を増やすと（例えば、従来技術のように８個設けると）、各通路から噴射される噴射水の圧力が低下し、汚れを確実に落とすことができなくなる。   In the two embodiments described above, two main injection passages 32 and two sub-injection passages 33 are provided, but this allows the high-pressure jet water from each passage to be strong, Dirt inside the drain pipe can be removed more effectively. Incidentally, when the number of passages is increased (for example, when eight passages are provided as in the prior art), the pressure of the water jetted from each passage is lowered, and the dirt cannot be reliably removed.

また、上記実施形態においては、主噴射通路３２の口径を、副噴射通路３３の口径よりも大きく設定しているが、本発明はこれに限定されるものではなく、前者を後者より小さくしたり、また、同一に設定することもできる。また、主噴射通路３２および副噴射通路３３の傾斜角度α，βも適宜設定することができる。これらは、希望するローター３０の回転数や前進速度によって適宜設定することができる。   In the above embodiment, the diameter of the main injection passage 32 is set larger than the diameter of the sub-injection passage 33, but the present invention is not limited to this, and the former may be made smaller than the latter. It is also possible to set the same. Further, the inclination angles α and β of the main injection passage 32 and the sub injection passage 33 can be set as appropriate. These can be set as appropriate according to the desired rotation speed and forward speed of the rotor 30.

表１は、副噴射口を設けない比較例と、副噴射口を設けた実施例との比較表である。   Table 1 is a comparison table between a comparative example in which no sub-injection port is provided and an example in which the sub-injection port is provided.
