〔産業上の利用分野〕
本発明は、局部を水洗する洗浄式トイレの水噴射方法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a water injection method for a flushing toilet for flushing private parts.
従来は、水を断続的に噴射する場合は、例えば、特開昭
５９−１７９９４３号公報に記載されているように、バ
ルブで配管通路を連続的に開閉して断続的に噴射してい
た。Conventionally, when injecting water intermittently, water was injected intermittently by continuously opening and closing a piping passage with a valve, as described in, for example, Japanese Patent Laid-Open No. 59-179943.
従来の断続流の作り方では、流水通路を自動開閉するバ
ルブ（例えば、モーター駆動のロータリーバルブや電磁
弁等）を使用する為に、高価になるという問題があると
ともに、これらのバルブが騒音（振動音）の発生源にな
るという問題がある本発明は、高価なロータリーバルブ
等を用いず、安価でかつ騒音を生じづに局部洗浄に適し
た断続流を作る方法を提供する事を目的としている。Conventional methods of creating intermittent flow use valves (e.g., motor-driven rotary valves, solenoid valves, etc.) that automatically open and close the water flow passage, which is expensive, and these valves also generate noise (vibration). The purpose of the present invention is to provide a method for creating intermittent flow suitable for local cleaning at low cost and without producing noise, without using expensive rotary valves or the like. .
上器目的を達成する為に、本発明では噴射ノズルとして
流れを二方向に交互に切り換える機能を有する流体素子

り換え、一方の流れは洗浄水として噴射し、他方の流れ
は、そのまま便器に流したり、送水ポンプの吸い込み部
や貯水タンク等へ戻す事により、断続的な洗浄水の噴射
流を得る事を特徴とする。In order to achieve this purpose, the present invention uses a fluid element as an injection nozzle that has the function of alternately switching the flow in two directions. The other stream is flowed as it is into the toilet bowl or returned to the suction part of the water pump, water storage tank, etc. to obtain an intermittent jet stream of flushing water.
本発明で噴射ノズルとして用いる流体素子は、その種類

１１と呼ばれる、切換えられる流れの出力通路を二つの
噴出口１０ａと１０ｂに分割する物が設けられている。Although the fluid element used as the injection nozzle in the present invention is of any type, for example, a swelling fluid element attached to a side wall is used. As shown in FIG. 2, a rapidly expanding channel 10 is provided at the outlet of a rectangular nozzle called a main jet channel 9, and a splitter 11 is placed on the axis of the main jet channel 9 in the rapidly expanding channel 10. , something is provided which divides the output path of the flow to be switched into two jets 10a and 10b.
また、主噴流路９直後の急拡大流路１０の各噴出口１０
ａ、１０ｂ側壁部には、制御流路口１２ａおよびそれら
に連なる制御流路１２が接続されている。In addition, each jet port 10 of the rapidly expanding flow path 10 immediately after the main jet flow path 9
A control flow path port 12a and a control flow path 12 connected thereto are connected to the side wall portions a and 10b.
主噴流路９より洗浄水の流れが噴出されると、コアンダ
ー効果によりその流れは、急拡大流路１０の側壁のどち
らか一方に付着して流れ、その側壁側の噴出口１０より
噴出する。この時、流れと付着している側壁との干渉作
用により低圧の付着渦が発生する。前記、制御流路１１
を互いに配管１３で接続すると、流れが付着している側
へ制御流路１２を通じ、付着していない側へ流れが誘起
され、発生している付着渦部の圧力が高まり、ある一定
の圧力以上になると流れが不安定となり、流れが反対側
の側壁に付着する事となり、反対側の噴出口１０より噴
出する事となる。以後これが継起して流れが振動する。When a stream of cleaning water is ejected from the main jet flow path 9, the flow adheres to one of the side walls of the rapidly expanding flow path 10 due to the Coander effect, and is ejected from the jet port 10 on the side wall side. At this time, a low-pressure attached vortex is generated due to interference between the flow and the attached side wall. The control flow path 11
When these are connected to each other by piping 13, the flow passes through the control flow path 12 to the side where it is attached, and the flow is induced to the side where it is not attached, and the pressure of the generated attached vortex increases, and the pressure exceeds a certain level. When this occurs, the flow becomes unstable, the flow adheres to the opposite side wall, and is ejected from the opposite side wall. After this, this continues and the flow oscillates.
すなわち、流れが交互に二方向に切換えられる事となる
。That is, the flow is alternately switched in two directions.
この交互に切り換えられる流れの一方を洗浄水として大

水タンクに戻す事により、断続的な洗浄水を得る事がで
きる。By jetting one of these alternately switched flows into the atmosphere as cleaning water and returning the other to the suction part of the water pump 7 or the water storage tank, intermittent cleaning water can be obtained.

れが安定し、切換え作用が行なわれなくなる為である。An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, in the present invention, a layered fluid element 8 with a side wall is used as an injection nozzle, and the discharge port of the water pump 7 and the water supply port 9a of the main jet flow path 9 of the element 8 are connected. Connect by piping. Further, a branch part 6 is provided on the upstream side of the water pump 7, and this branch part 6 and one of the jet ports 10a of the fluid element 8 are connected to each other.
Connect the piping. Furthermore, a throttle section 4 is provided by arranging a throttle or the like on the upstream side of the branch section 6, so that the pump inlet pressure is maintained at approximately atmospheric pressure. This is because, in order to maintain the flow switching effect of the fluid element 8, the outlet pressures of the re-jet ports 10a and 1Ob need to be approximately equal. This is because if either outlet pressure becomes lower than the other, the flow will be stabilized in the lower one and no switching action will take place.
ヒーター等を配した湯温調節部５は、分岐部６の上流側
へ配設し、流す水の温度を加温等して調節する。A hot water temperature adjusting section 5 equipped with a heater and the like is disposed upstream of the branching section 6, and adjusts the temperature of flowing water by heating, etc.
