Description

本発明はシャワーホースの先に接続している一般的なシャワーヘッドの代わりとなる吐水口部の形状に関するものであり、シャワーヘッドの様に吐水口に散水板を必要としないシンプルな構造で、ラッパ状に広がった吐水口部の開口壁に沿って吐水流が旋回しながらスプレー状に広がって吐水させることを可能にした吐水口部の構造である。 The present invention relates to the shape of the water outlet that replaces the general shower head connected to the tip of the shower hose, and has a simple structure that does not require a water spray plate at the water outlet, like the shower head. It is the structure of the water discharge port part which made it possible to spread and spray water in a spray form while the water discharge flow swirls along the opening wall of the water discharge port part spreading in a trumpet shape.

従来のシャワーヘッドはシャワーホースからの流水が筒状のシャワーヘッドの握り部の中を通り、その先の複数の穴が開口されている散水板の各穴を通って、複数のシャワー状の吐水流となって散水する構造となっており、そのため、散水板にあけられた穴の数や穴の径、穴の形状などがシャワー体感を左右する重要な要素となっていた。
（特許文献１）（特許文献２）（特許文献３）（特許文献４）（特許文献５）In a conventional shower head, the water flowing from the shower hose passes through the grip of the tubular shower head and passes through each hole of the water spray plate where a plurality of holes are opened. As a result, the number of holes drilled in the water spray plate, the diameter of the holes, and the shape of the holes were important factors that influenced the shower experience.

散水板が無くても快適なシャワー体感が得られるようなスプレー状の散水が確保され、シャワーホースの先に取り付けることのできる吐水口部をつくる。 A spray-like water spray is provided so that a comfortable shower experience can be obtained without a water spray plate, and a spout can be attached to the tip of the shower hose.

シャワーホースから流れ込んでくる流水に本体入口部で旋回流としてのひねりを加えながら、内径を絞り込んで流速を速め、さらにそれをラッパ状に開放された吐水口の内壁に沿ってスプレー状に拡散させて放出することにより、散水板の複数の穴から放出されるシャワーとは異なるが、快適なシャワー体感が得られる構造の吐水口部を作る。 While adding a twist as a swirling flow at the inlet of the main body to the flowing water flowing in from the shower hose, the inner diameter is narrowed to increase the flow velocity, and it is further diffused in the form of a spray along the inner wall of the spout opening. The water outlet is constructed so that a comfortable shower experience can be obtained, although it is different from the shower discharged from the plurality of holes of the water spray plate.

この吐水口部の通水路の内径が徐々に絞り込まれてから、再度、徐々に広がっていく、いわゆる鼓状の構造を作るには、樹脂や鋳物などで一体に作っても良いし、ラッパ状の筒を二本つくり、それぞれのラッパの吹き口部分で接続することにより、鼓状の構造を作っても良い。 In order to create a so-called drum-like structure that gradually expands again after the inner diameter of the water passage at the water outlet is gradually narrowed, it can be made integrally with a resin or a casting, or a trumpet shape. A drum-like structure may be made by making two cylinders and connecting them at the mouth of each trumpet.

流速をあげるためには流水路を入口側から出口側に向かって口径が小さくなるようにテーパー状に絞り込むとともに、さらに流速をあげ、スムーズな流れとなるよう、流水路の入口部分に円盤状のプレートで、そのプレートに複数のねじれた穴が開口されていて、流水に旋回流を強制的に起こさせるための部材を組み込む。 In order to increase the flow velocity, the flow channel is narrowed in a tapered shape so that the diameter decreases from the inlet side to the outlet side, and the flow rate is further increased so that a smooth flow can be achieved by providing a disk-like shape at the inlet portion of the flow channel. In the plate, a plurality of twisted holes are opened in the plate, and a member for forcing a swirling flow in the flowing water is incorporated.

吐水をスプレー状に拡散させるための吐水口部のラッパ状に広がった内壁に、意図的に凹凸を付けることにより、吐水流に乱流を起こさせ、シャワー体感を向上させる。 By intentionally making irregularities on the trumpet-shaped inner wall of the spout for diffusing the spout in the form of a spray, turbulence is caused in the spout and the shower experience is improved.

流水に通水路の入口部のプレートでねじれの回転を加え、流水を旋回させながらテーパー状に狭くなった狭隘部を通すことで、流速を速め、それをラッパ状に広がった、ラッパ管の内壁に沿って旋回させながら吐水させることで、スプレー状に拡散して吐水させることができ、散水板が無くても、シャワーと類似の体感を確保することができる。 The inner wall of the trumpet pipe that is twisted by the plate at the inlet of the water flow channel and passed through a narrowed portion that narrows in a tapered shape while swirling the flowing water, increasing the flow velocity and spreading it in a trumpet shape. The water can be diffused in the form of a spray to be discharged while being swirled along, and a sensible experience similar to that of a shower can be ensured even without a watering plate.

鼓状の通水路を作るためのラッパ状の筒の接続部分は同じサイズの口径同士で接続しても良いが、異形サイズで接続しても良く、その場合は接続部において、出口側の内径を大きくすることで、流水の圧力を急激に空気中に開放したり、逆に接続部の出口側の内径を狭めて、通水路を通ってきた水流の中心部以外の水流が狭い出口側のトンネルの開口の周囲の壁に当るようにして、流水に乱流を起こさせ、その後、急激に空気中に開放することにより、今までの複数の穴の開いた散水板によるシャワーとは異なったシャワー体感を得ることができる。 The connection part of the trumpet-shaped tube for making the drum-shaped water passage may be connected with the same size of the caliber, but may be connected with different sizes, in which case the inner diameter of the outlet side at the connection part By increasing the pressure, the pressure of the flowing water is suddenly released into the air, or conversely, the inner diameter of the outlet side of the connection part is narrowed, so that the water flow other than the center part of the water stream that has passed through the water passage is narrower It is different from the conventional shower with a multi-hole sprinkler by making it turbulent in the flowing water so that it hits the wall around the tunnel opening and then suddenly opening it into the air. A shower experience can be obtained.

また、該器具の吐水口部を水中に沈めた状態で、該器具に４０度程度の温水を通すと、温水中に含まれた空気が旋回しながら高速で狭隘部を通って圧縮され、その後、急激に水中に開放され、圧力が下がることにより、水中で吐水とともに微細な気泡が発生する。これにより、水中で微細な気泡を発生させる装置としての効果も確認することができた。 In addition, when warm water of about 40 degrees is passed through the device with the water outlet of the device submerged in water, the air contained in the warm water is compressed through the narrow portion at high speed while swirling, and then When the pressure is suddenly released into the water and the pressure drops, fine bubbles are generated together with the water discharged in the water. Thereby, the effect as an apparatus which produces | generates a fine bubble in water was also able to be confirmed.

旋回流を起こさせるための円盤状のプレート部材に開口された、複数のねじれた穴の開口の口径の合計面積と穴のねじれ角度を変化させることにより、流速や水流のひねり角度を変化させることができる。試作品での実験では円盤状のプレートの形状を直径１３．５ミリとしたが、これは給水・給湯管の管径が１５Ａの管径であったためであり、このサイズに限定はされない。また、円盤状のプレートに開口された、ねじれた流水路に入口側から出口側へ向けて口径が小さくなるようなテーパーを付けても良い。 By changing the total area of the diameters of the openings of the twisted holes and the twist angle of the holes, which are opened in the disk-shaped plate member for causing the swirling flow, the flow velocity and the twist angle of the water flow are changed. Can do. In the experiment with the prototype, the shape of the disk-shaped plate was 13.5 mm in diameter, but this was because the diameter of the water / hot water supply pipe was 15A, and the size is not limited. Further, the twisted water channel opened in the disk-shaped plate may be tapered so that the diameter decreases from the inlet side to the outlet side.
