向上するという特徴を持つ。[Conventional technology 1] Recently, some cleaning devices such as sanitary toilet seats and bathing showers have been using nozzles that utilize fluid oscillation collectors that oscillate water jets from side to side by utilizing the pressure difference of the water flow. It is being said. This kind of fluid oscillation element nozzle has no moving parts,
Due to its simple structure, no maintenance is required and V'a can be done at low cost.6 In addition, the water jet continuously oscillates due to the water pressure of the water flow, resulting in a high cleaning effect and an improved feeling of pleasure.

かず、噴射水は発振しない。Problem 1 to be Solved by the Invention However, in such a configuration, as shown in FIG. The air then rises from the main nozzle 5 to a reduced pressure chamber communicating with the atmosphere. When the jetted water ejected from the main nozzle 5 passes through the depressurized central waterway 7, which communicates with the atmosphere, it is caused by the coang effect on the left and right walls (ν).
It sticks to any part of the body. Since feedback channels 10 are formed on both sides of the central water channel 7, the water jetted from the main nozzle 5 passes while adhering to the left and right walls of the central channel 7 alternately. However, if the width of the central waterway 7 and the width of the water outlet 9 are not appropriate, the water jetted from the main nozzle 5 may not adhere to the wall surface of the central waterway 7 and may travel straight, or the water may be disposed on the left or right side. There is no clear pressure difference in the feeder water channel 10, and the jetted water does not oscillate.
一方、中央水路7に大気と連通した空気孔11を設ける

じるなどの問題があった。On the other hand, by providing the air hole 11 communicating with the atmosphere in the central waterway 7, the water jetted from the main waterway 77 mixes air due to the ejector effect. 11 is incorrectly positioned, the internal pressure balance of the central waterway 7, which is a decompression chamber, may be disrupted, leading to problems such as water being jetted from the air holes 11 or malfunctioning oscillation of water jetted from the water spout 9. Ta.

Feedback waterway 10
The swirling water jet from the main nozzle 5 sucking air from the air hole 11 deflects the water jet from the main nozzle 5 and helps it adhere alternately to the wall surface of the central waterway 7, and the left and right wall surfaces of the fluid oscillation concentrator nozzle. This improves the responsiveness of the switch operation and greatly improves the oscillation performance even when the amount of water injected is low.

ル5の出口との合流点の領域20に設けている。212I indicates a water channel pattern formed in the nozzle body 1 for oscillation. The water supply pipe 4 is an introduction waterway 6 which is connected to the main part of the fluid oscillation collector nozzle A and has a single-shaped structure.
downstream of the main nozzle 5, there is a central waterway 7 wider than the main nozzle 5, and further downstream of the central waterway 7, a widening spout 9 having a water flow zone M zone 8 is formed. There is. Further, on both sides of the central waterway 7, a pair of feedback waterways 10 are formed on the left and right sides for causing a part of the jet water separated from the water flow separation zone 8I to flow swirlingly to the outlet of the main nozzle 5. The air hole 11 is located at the center of the central waterway 7 and at the return point of the swirling flow of the feedback waterway 10, that is, the main /f,
It is provided in a region 20 at the confluence with the exit of the pipe 5.

ためのもので、分離効果を上げるためには中央水路7の
幅と路間等にすることが望ましい。By providing the air hole 11 at the part where the water is injected from the main nozzle 5 at the highest speed, the air suction force due to the ejector effect is the greatest, and it is possible to mix in air to the extent of about 30% of the amount of water to be injected. On the downstream side of the air hole 11, the apparent volume increases by about 1.3 times due to air mixing, so in order to cause the wall adhesion phenomenon due to the Fang effect, the width of the central water 8@7; 11" 5 width ladle 2
About double that is desirable. In addition, the water flow #11 of the spout 9 actively introduces a part of the jet water adhering to the wall surface on one side to the feedbank waterway 10 side and closes it, making it different from the feedback waterway 10 on the opposite side. It serves to generate pressure, and in order to increase the separation effect, it is desirable to have the width of the central waterway 7 and the space between the channels.
これらの一定の範囲を越尤ると内圧の・ずランスがくず
れ、棒状またはロウツク状の噴射になり、噴射水は安定
した発振状態にならないし、エア混入量も低下する。If these certain ranges are exceeded, the internal pressure balance will be disrupted, resulting in rod-shaped or candle-shaped jets, the jet water will not be in a stable oscillation state, and the amount of air mixed in will also decrease.

流分a帝8aで左側のフィードバック水路10aに噴射
水の一部が導入される。The operating state will be explained in detail using the fpJ2 diagram. First, if the water jetted from the main jet 5 sucks air through the air hole 11 and adheres to the left side of the central waterway 7 due to the coring effect, then the water jetted from the left water flow aperture 8a flows into the feedback waterway 10a on the left side. Some of them will be introduced.

二付着方向を変更させてP’<P″となり、以後噴射水
は付着方向を自動的に切り替えるため、吐水口9ららの
噴射水は自動的に発振状態を繰り返す。Therefore, due to the pushing action in the water flow separation zone 8 and the saccilane effect at the outlet of the main nozzle 5, the left feedbank waterway 108 is closed with water! ! As a result, a pressure difference is generated in the fiber/return waterway 1 (Oa) on the right side, and when P >P', the pressure in the feedback waterway (Oa) on the left side increases. Main nozzle 5
The water jetted out from the low-pressure side, that is, the right wall of the central waterway 7;
2, the adhesion direction is changed so that P'<P'', and thereafter the ejected water automatically switches the adhesion direction, so the ejected water from the water spout 9 and others automatically repeats the oscillation state.

ーズに起こるという効果がある。Here, the water jetted from the main nozzle 5 travels straight to the air hole 11, and after being mixed with air, it adheres to either the left or right wall of the central waterway 7, but the air hole 11 is connected to the outlet side 12 of the feedback waterway 10. By installing the swirling water flow from the feedbank waterway 10 on the high-pressure side toward the low-pressure side on the opposite bank, reducing the opening area of the central waterway 7, the opening area of the central waterway 7 is reduced. This has the effect that minute pressure differences can be detected with high sensitivity, and the backlash movement to the left and right walls of the central waterway 7 can occur smoothly.

ある。Figure 3 shows the oscillation v between the width of the main /'
Area A is shown, but the width of the central waterway 7 and the width of the water flow separation zone 8 are preferably the width between the lanes (about 0.8 to i, 2 mm), and both are 1.7 mm, which is the width of the width of the 72" square 5. 2. There is a region T-p of stable oscillation that is about 'E times.As shown in 2, the narrow openings of the medium-fired waterway 7 and the spout 9 are placed between the roads, etc., and the main/tessellation 5 By setting the width to the appropriate size, the internal pressure balance in the fluid oscillation element nozzle A can be maximized, and the air mixing rate can be maximized, making the oscillation characteristics from the water spout 9 uniform and stable. It is something.
