Figure 13 (a) is the lateral view of expression piston portion 20, and Figure 13 (b) is the vertical view of expression piston portion 20.

As Figure 13 (a) and (b), nozzle casing 401 has front end and seals into hemispheric cylindrical structure, is the integrative-structure that does not have seam.The plane is formed partly at the top at the leading section of nozzle casing 401, and the central portion on this plane forms squit hole 401a.Nozzle casing 401 is processed to form by the stainless steel deep-draw.

Because nozzle casing 401 does not have seam, so even foul sticks on the nozzle casing 401 also flushing, very health easily.Stainless steel has antibacterial action, so can not breed at the surface bacteria of nozzle casing 401.

Nozzle casing 401 is made of stainless steel, thereby can realize thin-walled property under the situation of the intensity of guaranteeing nozzle casing 401, can realize the miniaturization of buttocks nozzle 1.This occasion is not even the clean water of supplying with in nozzle casing 401 after the pressurization can produce distortion yet.The caliber of nozzle casing 401 for example can be 10mm, and wall thickness for example can be about 0.2mm.

And because nozzle casing 401 is processed to form by deep-draw, so smooth surface, foul is difficult for adhering to.And the surface of nozzle casing 401 has gloss, and the user can feel clean feel.

Figure 14 is the sectional view of expression buttocks nozzle 1.

As shown in figure 14, buttocks nozzle 1 is made of piston portion 20, cylinder body cylindraceous portion 21, seal washer 22a, 22b and spring 23.

Upper surface in runner fluidic junction 404 forms the hole portion 25 that the clean water of ejection is used.Be provided with retainer 26a, the 26b of flange shape in the rear end of piston portion 20.In addition, be separately installed with seal washer 22a, 22b at retainer 26a, 26b.

Be formed with from rear end face and the runner 27a that a flow-path tube 403 is communicated with in the inside of two flow-path tubes 402, also be formed with the runner 27c that is communicated with the front end face of two flow-path tubes 402 from the periphery of the piston portion 20 between retainer 26a and the retainer 26b.

Be formed with the runner 27b that is communicated with runner fluidic junction 404 from the runner 27a of two flow-path tubes 402 in the inside of a flow-path tube 403.Space between a nozzle casing 401 and the flow-path tube 403 becomes runner 27d.The concrete structure such as the back of runner fluidic junction 404 are chatted.

On the other hand, cylinder body portion 21 partly is made of the major diameter of the small diameter portion of front, the mid portion with mid diameter, rear end side.Thus, but between small diameter portion and mid portion, form the stop surface 21c of the retainer 26a of piston portion 20, but mid portion and large-diameter portion form the stop surface 21b of the retainer 26b of piston portion 20 by seal washer 22b butt between dividing by seal washer 22a butt.

Be provided with at the rear end face of cylinder body portion 21 and clean water inlet 24a, on the periphery of the mid portion of cylinder body portion 21, be provided with and clean water inlet 24b, on the front end face of cylinder body portion 21, be provided with peristome 21a.The inner space of cylinder body portion 21 becomes temperature change buffer part 28.Clean water inlet 24a and be eccentrically set on the position different with the central axis of cylinder body portion 21.

Clean water inlet 24a and be connected, clean water inlet 24b and be connected with the clean water out 143c of the transfer valve 14 of Fig. 8 with the clean water out 143d of the transfer valve 14 of Fig. 8.Piston portion 20, is cleaned water inlet 24b and is communicated with the runner 27c of two flow-path tubes 402 when the most outstanding from cylinder body portion 21.The concrete condition of the action when this clean water inlet 24b is connected with runner 27c as hereinafter described.

Piston portion 20 inserts in the cylinder body portion 21 movably, so that retainer 26b is positioned at temperature change buffer part 28, leading section is outstanding from peristome 21a.

And spring 23 is provided between the periphery of peristome 21a of the retainer 26a of piston portion 20 and cylinder body portion 21, to the rear end side application of force of piston portion 20 towards cylinder body portion 21.

Form minim gap between the outer peripheral face of retainer 26a, the 26b of piston portion 20 and the inner peripheral surface of cylinder body portion 21, form minim gap between the inner peripheral surface of the peristome 21a of the outer peripheral face of piston portion 20 and cylinder body portion 21.

Then the action to the buttocks nozzle 1 of Figure 14 describes.Figure 15 is the sectional view of action usefulness of the buttocks nozzle 1 of explanation Figure 14.

At first, shown in Figure 15 (a), do not supply with when cleaning water from clean water inlet 24a, the 24b of cylinder body portion 21, piston portion 20 retreats towards the direction opposite with arrow X under the elastic force effect of spring 23, is accommodated in the cylinder body portion 21.Consequently, piston portion 20 becomes the least outstanding state from the peristome 21a of cylinder body portion 21.At this moment, in cylinder body portion 21, there is not formation temperature change buffer part 28.

Then, shown in Figure 15 (b), begin to supply with when cleaning water from the clean water inlet 24a of cylinder body portion 21, piston portion 20 overcomes spring 23 under the pressure effect of cleaning water elastic force advances towards the arrow directions X gradually.Thus, formation temperature change buffer part 28 in the cylinder body portion 21 is cleaned water simultaneously and is flowed in the temperature change buffer part 28.

Clean water inlet 24a is arranged on the eccentric position with respect to the central axis of cylinder body portion 21, so the clean water that flows into temperature change buffer part 28 refluxes into vortex shape shown in arrow V.The part of the clean water of temperature change buffer part 28 flows through the minim gap between the inner peripheral surface of the outer peripheral face of retainer 26a, 26b of piston portion 20 and cylinder body portion 21, flow out from the minim gap between the inner peripheral surface of the peristome 21a of the outer peripheral face of piston portion 20 and cylinder body portion 21, flow through runner 27a, 27b, 27c, the 27d of piston portion 20 simultaneously and supply with runner fluidic junction 404, ejection is arranged slightly from hole portion 25.

When piston portion 20 was advanced further, then shown in Figure 15 (c), retainer 26a, 26b contacted with stop surface 21c, the 21b water-stop of cylinder body portion 21 by seal washer 22a, 22b.Thus, the runner of the minim gap between the inner peripheral surface of the peristome 21a of outer peripheral face from the minim gap between the inner peripheral surface of the outer peripheral face of retainer 26a, the 26b of piston portion 20 and cylinder body portion 21 to piston portion 20 and cylinder body portion 21 is cut off.

And the runner 27c, the 27d that flow through piston portion 20 from the clean water of cleaning water inlet 24b supply supply with runner fluidic junction 404.Thus, flow through runner 27a, b and mix with the clean water that flows through runner 27c, 27d supply to the clean water of runner fluidic junction 404 supplies, and from 25 ejections of hole portion.

Figure 16 is the figure of explanation runner fluidic junction 404 usefulness.Figure 16 (a) is the vertical view of the leading section of piston portion 20, and Figure 16 (b) is the D-D line sectional view of Figure 16 (a), and Figure 16 (c) is the E-E line sectional view of Figure 16 (a).

Shown in Figure 16 (a), the diameter of squit hole 401a forms greatlyyer than hole portion 25.Thus, the clean water that sprays from hole portion 25 can not collide with squit hole 401a, can not hinder the ejection of cleaning water.

Shown in Figure 16 (b), surround hole portion 25 ground on the top of runner fluidic junction 404 and form circular groove 404a, O shape ring 404b is installed in groove 404a.O shape ring 404b closely contacts with the inner peripheral surface of nozzle casing 401, and the clean water of runner 27d can not flow out from the squit hole 401a of nozzle casing 401.In addition, even the leading section of nozzle casing 401 adheres to foul, foul can directly not enter in the runner 27d from squit hole 401a yet.

Moreover even foul is in the squit hole 401a of nozzle casing 401 enters hole portion 25 time, foul also can be discharged at once from the clean water of hole portion 25 ejections.Thus, make the inside of nozzle casing 401 remain cleaning.

Leading section in runner fluidic junction 404 forms fixed-site sheet 404c.The front end of fixed-site sheet 404c is supported on the inner peripheral surface of front end of nozzle casing 401, thereby the position of runner fluidic junction 404 is fixed.

Upper end to lower end in the inside of runner fluidic junction 404 from runner fluidic junction 404 forms hole portion 25, the 25a of contracted flow portion, cylindric volute chamber 25b and the 25c of contracted flow portion successively.

The clean water of runner 27d flows through the 25c of contracted flow portion supplies with cylindric volute chamber 25b.The internal diameter of the 25c of contracted flow portion reduces continuously towards cylindric volute chamber 25b, so rise continuously at the flow velocity of the mobile clean water of the 25c of contracted flow portion.

The clean water of supplying with cylindric volute chamber 25b flows into the contracted flow 25a of portion.The internal diameter of the 25a of contracted flow portion reduces continuously towards hole portion 25, so rise continuously at the flow velocity of the mobile clean water of the 25a of contracted flow portion.The clean water of supply hole portion 25 sprays towards human body.

Shown in Figure 16 (c), cylindric volute chamber 25b is communicated with runner 27b.The clean water of supplying with from runner 27b is given revolving force and is produced rotating flow the clean water of supplying with cylindric volute chamber 25b from runner 27d among cylindric volute chamber 25b described later.

Here, the flow velocity at the mobile rotating flow of cylinder interior is described.Figure 17 (a) is the ideograph of flow velocity of the rotating flow of explanation cylinder interior.

The rotating flow that flows in cylinder interior of Figure 17 (a) is in stable state.Shown in Figure 17 (a), the fluid that flows in cylinder interior is justified shape ground with the centres of cylinder and is flowed.Flow velocity at the center of cylinder rotating flow is 0, and the flow velocity of rotating flow increases with distance apart from the center with being directly proportional, and rotating flow forms the vortex that does not have vorticity.

But from being near the zone in border to the outside the cylinder inner peripheral surface, rotating flow is subjected to resistance from the cylinder inner peripheral surface.Below this border is called laminar flow boundary BL.The outside at laminar flow boundary BL forms so-called boundary layer, and the flow velocity of rotating flow sharply descends, and is 0 at the inner peripheral surface of cylinder.Therefore, the flow velocity of rotating flow is maximum at laminar flow boundary BL place.

Figure 17 (b) is the ideograph of the rotating flow of the clean water among the cylindric volute chamber 25b of explanation.In Figure 17 (b), clean the mobile of water and represent with arrow Q1.Shown in Figure 17 (b), runner 27a is communicated with cylindric volute chamber 25b, so that the extended line of the wall in the outside of runner 27a constitutes tangent line with respect to laminar flow boundary BL.Thus, the clean water of supplying with from runner 27a can apply revolving force to cleaning water under the situation of the resistance of the inner peripheral surface that is not subjected to cylindric volute chamber 25b.The clean water of supplying with from runner 27a applies revolving force to the most peripheral of the vortex that does not have vorticity that forms in cylindric volute chamber 25b, can not upset the vortex that does not have vorticity.

And, shown in Figure 16 (b), because cylindric volute chamber 25b does not have the bottom surface, so the suffered resistance of the rotating flow that flows in cylindric volute chamber 25b is little.

As mentioned above, among the cylindric volute chamber 25b in embodiment 1, can little in flow resistance, can not upset to make under the situation of the vortex that does not have vorticity and clean the water rotation.

Then, the sectional area of the runner of the clean water of supplying with buttocks nozzle 1 being flowed through with reference to Figure 18 and Figure 19 changes and describes.

Figure 18 is the sectional view of the leading section of expression buttocks nozzle 1, and Figure 19 (a) is the X-X line sectional view of Figure 18, and Figure 19 (b) is the Y-Y line sectional view of Figure 18, and Figure 19 (c) is the Z-Z line sectional view of Figure 18.

Shown in Figure 19 (a), the sectional area of sectional area S1 indication window portion 25.Shown in Figure 19 (b), sectional area S2 represents the sectional area of cylindric volute chamber 25b.Shown in Figure 19 (c), the sectional area S3 of runner 27d represents the sectional area in the zone except a flow-path tube 403 in the inner space of nozzle casing 401.Between sectional area S1, S2, S3, the relation of S1＜S2＜S3 is set up.

Because the sectional area S3 of runner 27d is bigger, so little in the pressure loss of the mobile clean water of runner 27d.Thus, cleaned water before supplying with runner fluidic junction 404, clean water is kept high pressure.

In addition, the sectional area of runner 27d, the 25c of contracted flow portion, cylindric volute chamber 25b, the 25a of contracted flow portion and hole portion 25 reduces successively gradually, so the runner loss is little, the pressure loss of cleaning water reduces.The flow of water when thus, cleaning water from 25 ejections of hole portion increases and is efficient.

As d1, the diameter of cylindric volute chamber 25b is as d2 with the diameter of hole portion 25, and then d2/d1 is preferably about 2～5.Thus, can when reducing the runner loss, improve from the flow velocity of the clean water of hole portion 25 ejections.

In addition, in the buttocks nozzle 1 of embodiment 1, therefore the cylindric space between the inner peripheral surface of nozzle casing 401 and the flow-path tube 403 can increase the sectional area of cleaning water flow passage as the runner of cleaning water when making piston portion 20 miniaturizations.

Figure 20 is a pattern sectional view of seeing that from the side the leading section of piston portion 20 obtains.

As shown in figure 20, runner 27d is communicated with the 25c of contracted flow portion from the below, and runner 27b is communicated with the periphery of cylindric volute chamber 25b cylindraceous.Flow through runner 27c, 27d from the clean water of the clean water out 143c of transfer valve 14 and supply with, and flow through cylindric volute chamber 25b and the 25a of contracted flow portion sprays as linear flow from hole portion 25 to the 25c of contracted flow portion.Flow through runner 27a, 27b from the clean water of the clean water out 143d of transfer valve and supply with, and flow through the 25a of contracted flow portion from 25 ejections of hole portion to cylindric volute chamber 25b.

The clean water of supplying with to cylindric volute chamber 25b from runner 27b as shown in Figure 19, the curve form of the inner peripheral surface by cylindric volute chamber 25b and flowing with vorticity makes the clean water rotation of supplying with from runner 27d.

Like this, in cylindric volute chamber 25b, make clean water rotation from runner 27b from the clean water of runner 27d, the clean water of rotation is from 25 ejections of hole portion.

For example, the flow of the clean water that the flow-rate ratio of the clean water of supplying with from runner 27b is supplied with from runner 27d for a long time, the clean water that mixes in cylindric volute chamber 25b is kept the vorticity that the curve form owing to cylindric volute chamber 25b cylindraceous forms strongly, so shown in the arrow H of Figure 20, spray as the dispersion rotating flow with big angle.

And the flow of the clean water of supplying with from runner 27b when the flow-rate ratio of the clean water of supplying with from runner 27d for a long time, the clean water that mixes in cylindric volute chamber 25b is kept linear state strongly, so shown in the arrow S of Figure 20, spray as linear flow with narrow angle.

Therefore, the motor M of the 4 pairs of transfer valves 14 of control part by Fig. 3 controls, and the flow-rate ratio of cleaning water out 143c, 143d is changed, and changes thereby can make from the ejection form of the clean water of hole portion 25 ejections.

In addition, as shown in Figure 17, the rotating flow that produces at cylindric volute chamber 25b becomes disorderly few vortex, so form the disorderly circle that do not have of whole evenly diffusion from the clean water of hole portion 25 ejections.In addition, as shown in figure 20,, also can form from central division to peripheral part and have the cross section of cleaning water equably even from the jet flow diffusion angle of the clean water of hole portion 25 ejection when big.

In embodiment 1, behind the flow of water by-pass cock 302a that presses Fig. 2, the flow that the flow-rate ratio of clean water out 143c is cleaned water out 143d is big, and the ejection form of cleaning water is near linear flow.And after pressing flow of water by-pass cock 302b, the flow that the flow-rate ratio of clean water out 143d is cleaned water out 143c is big, and the ejection form of cleaning water is near disperseing rotating flow.

In addition, for example concerning the combining an of flow-path tube 403 and runner fluidic junction 404 grades, so lower because keep the fluid pressure air tightnesses to require by nozzle casing 401.Therefore, buttocks nozzle 1 can easily be assembled.

Figure 21 is the figure that explanation is used from the pressure variance of the clean water of hole portion 25 ejections of buttocks nozzle 1.

The dotted line P1 of Figure 21 represents the pressure variance of nozzle casing 401 by the clean water of rubber-like material (for example plastics) when forming.When the nozzle casing 401 of buttocks nozzle 1 is made of the rubber-like material, absorb by nozzle casing 401 by the pressure of the clean water after pump 13 pressurization, the pressure of cleaning water descends, and pressure variance reduces.

And the nozzle casing 401 among the embodiment 1 is made of stainless steel, is not absorbed by nozzle casing 401 so clean the pressure of water, and the pressure variance of cleaning water does not descend.

Here, the maximum pressure of the clean water when nozzle casing 401 is formed by the rubber-like material is Pn3, and pressure variance is dH2, and the maximum pressure of the clean water when nozzle casing 401 is formed by stainless steel is Pn1, when pressure variance was dH1, then the relation of Pn1＞Pn3, dH1＞dH2 was set up.

Therefore, when nozzle casing 401 was made of stainless steel, then the pressure by 13 pairs of clean water pressurizations of pump can be utilized efficiently.

The nozzle casing 401 of embodiment 1 also can use the good stainless steel of antibiotic property that contains copper or silver.In addition, can use material not yielding, can be integrally formed.For example, both can use metals such as copper beyond the stainless steel, aluminium, nickel, chromium, also can use other alloys.

Among the embodiment 1, squit hole 401a is equivalent to squit hole, hole portion 25 is equivalent to hole portion, runner 27a is equivalent to the 1st runner, runner 27d is equivalent to the 2nd runner, fixed-site sheet 404c is equivalent to the location division, and runner fluidic junction 204 is equivalent to spray member, and the 25c of contracted flow portion is equivalent to peristome and the 1st space, cylindric volute chamber 25b is equivalent to the 2nd space, the 25a of contracted flow portion is equivalent to the 3rd space, and nozzle casing 401 is equivalent to cover member, and a flow-path tube 403 is equivalent to pipeline, O shape ring 402b is equivalent to containment member, pump 13 is equivalent to water booster system, and transfer valve 14 is equivalent to path selection device and flow regulator, and ceramic heater 505 is equivalent to heater.

The nozzle casing of lady's hip bath nozzle 2 is identical with the nozzle casing 401 of buttocks nozzle 1, also is made of stainless steel.And, omit the detailed structure of lady's hip bath nozzle 2 and the explanation of action.

Buttocks nozzle 1 clean is to be undertaken by cleaning from nozzle with the clean water of nozzle 3 ejections under the state in piston 20 is accommodated in cylinder body 21.Cleaning of lady's hip bath nozzle 2 also carried out with the clean of buttocks nozzle 1 the samely.

Figure 35 is the Y-Y line sectional view of the spray nozzle part 30 of Figure 32.In Figure 35, the nozzle of cleaning tube 26, lady's hip bath nozzle 2 for the nozzle of clearer and more definite buttocks nozzle 1 is cleaned tube 26c and nozzle and is cleaned cross sectional shape with nozzle 3, has omitted the details of outward appearance of the cylinder body 21d of the cylinder body 21 of the cross sectional shape of piston 20b of the piston 20 of buttocks nozzle 1 and lady's hip bath nozzle 2 and buttocks nozzle 1 and lady's hip bath nozzle 2.

As shown in figure 35, piston 20,20b have been taken in each inside of the clean tube 26 of nozzle, 26c.The cross section that nozzle is cleaned tube 26,26c forms circular, and the internal diameter that nozzle is cleaned tube 26,26c is bigger than the external diameter of the piston 20 that forms circular, 20b.At the clean tube 26 of nozzle, when 26c is oval, nozzle is cleaned the minimum diameter of tube 26,26c and is set for bigger than the maximum profile of piston 20,20b.

The upper surface of cleaning lady's hip bath nozzle 2 sides of tube 26 at nozzle is provided with the clean hole 26h of nozzle.The upper surface of cleaning buttocks nozzle 1 side of tube 26c at nozzle is provided with the clean hole 26hb of nozzle.Like this, nozzle is cleaned hole 26h, 26hb and respectively is provided with 1 respectively on the clean tube 26 of nozzle, 26c.

Here, the internal diameter of nozzle being cleaned tube 26 and the difference of the external diameter of piston 20 are as L2, and nozzle is cleaned the aperture of hole 26h as L1, then between L1 and L2, and the establishment of the relation of L1＜L2.

But, clean tube 26 at nozzle, when 26c is elliptical shape, the aperture L1 that nozzle is cleaned hole 26h sets to such an extent that to clean the difference L2 of external diameter of the minimum diameter of tube 26 and piston 20 than nozzle little.

The difference of the internal diameter of the clean tube of nozzle 26c and the external diameter of piston 20b and nozzle are cleaned between the 26hb of hole and are also had same relation.

The 1st nozzle cleans runner 71 and the 2nd nozzle is cleaned runner 72 is cleaned tube 26,26c respectively by nozzle clean hole 26h, 26hb and nozzle internal communication.Clean runner 71 of the 1st nozzle and the 2nd nozzle are cleaned runner 72 respectively as mentioned above from clean water importing space 70 branches of Figure 32, make the clean water of supplying with from clean water importing space 70 clean hole 26h, 26hb from nozzle and spray to the inside of clean 26 at nozzle, 26c.

By clean the clean water of hole 26h, 26hb ejection from nozzle, in the inside of the clean tube 26 of nozzle, 26c, piston 20,20b carry out following action.

And, cleaning the clean runner 72 of runner 71 and the 2nd nozzle from the 1st nozzle before water is cleaned in the inside ejection of the clean tube 26 of nozzle, 26c, piston 20,20b are positioned at the position in the axle center of clean 26 of offset nozzle, 26c as shown in figure 35. Piston 20,20b have the inside that is accommodated in cylinder body 21,21d under the state of swing property at the peristome 20X that utilizes Figure 33.

Figure 36 is the action usefulness of the piston 20 of runner 71 when water is cleaned in the ejection of the inside of the clean tube 26 of nozzle is cleaned in explanation from the 1st nozzle of Figure 32 a key diagram.Here, flowing of the clean water on the vertical cross-section direction of buttocks nozzle 1 being reached the mobile of piston 20 describes.Here, with the axle center of piston 20 as Cn.

Shown in Figure 36 (a), clean water and clean runner 71 is cleaned tube 26 to nozzle by the clean hole 26h of nozzle inside ejection from the 1st nozzle.This occasion, it is mobile like that shown in arrow R1, R2 in the inside that nozzle is cleaned tube 26 to clean water.

When the clean water of cleaning hole 26h from nozzle sprayed, piston 20 was positioned at the bottom that nozzle is cleaned tube 26.Piston 20 is under pressure because of (arrow R2) between the lower side inwall that flows into the clean tube 26 of piston 20 and nozzle cleans water, and axle center Cn moves.

Shown in Figure 36 (b), clean water when the inside ejection of cleaning tube 26 to nozzle from the state continuation of Figure 36 (a), then clean water is mobile like that shown in arrow R1, R2, R3 in the inside that nozzle is cleaned tube 26.

This occasion, by moving shown in Figure 36 (a), the piston 20 that moves to the top of the clean tube 26 of nozzle is under pressure because of (arrow R3) between the lateral side inwall that flows into the clean tube 26 of piston 20 and nozzle clean water, and axle center Cn moves.

Shown in Figure 36 (c), clean water when the inside ejection of cleaning tube 26 to nozzle from the state continuation of Figure 36 (b), then clean water is mobile like that shown in arrow R1, R2, R3, R4 in the inside that nozzle is cleaned tube 26.

The axle center Cn of piston 20 by cleaning the pressure that clean water produced that flows between the inwall of tube 26 at the outer peripheral face of piston 20 and nozzle, moves (vibration) and be that the center is small repeatedly on direction at random with the axle center that nozzle is cleaned tube 26.The vibration of the piston 20 that causes because of fluid pressure in the clean tube of nozzle 26 inside like this is the vibrations that are commonly referred to as self-excited vibration.

In order to produce such self-excited vibration, nozzle is cleaned hole 26h shown in the chain-dotted line of Figure 35, preferably is arranged to spray clean water to the outer peripheral face tangential direction (tangential direction of the some F of Figure 35) that nozzle is cleaned the axle center of tube 26 piston 20 when consistent with the axle center of piston 20.Piston 20 is best to be constituted in light weightly.

Like this, when cleaning water and flow through nozzle and clean hole 26h towards the outer peripheral face tangential direction ejection of piston 20, the flow velocity when then cleaning water and not damaging ejection, rotation effectively around the outer peripheral face of buttocks nozzle 1.

In addition, in order to produce self-excited vibration, nozzle is cleaned more than the preferably about 0.7mm in aperture of hole 26h and below about 1.0mm.

Figure 37 is the clean water of tube 26 inner ejections is cleaned in the stereogram that flows from expression to nozzle.

As shown in figure 37, clean of the outer peripheral face helical form rotation of the clean water of hole 26h ejection from nozzle, and flow out from the front end opening of the clean tube 26 of nozzle along piston 20.

Because of spray nozzle part 30 bodies tilt, thus the clean water of cleaning 26h ejection in hole from nozzle the outer peripheral face rotation of piston 20 and towards below flow, producing thus should be mobile.

Here, the clean hole 26h of nozzle vertically is provided with respect to the length direction of the clean tube 26 of nozzle.Thus, even when nozzle is cleaned hole 26h and cleaned water with very fast flow velocity ejection, clean water can directly not flow out from the front end opening that nozzle is cleaned tube 26 yet.

The clean water of cleaning 26h ejection in hole from nozzle is mobile along the outer peripheral face helically of piston 20, thereby clean water near the whole face the leading section of piston 20 is cleaned.And near the foul of front end that sticks to piston 20 can be more effectively cleaned in the self-excited vibration of the piston 20 when spraying by cleaning water.

To clean of the outer peripheral face rotation of the clean water of tube 26 inner ejections in order making, to need and to be adjusted to more than the setting from the flow velocity that nozzle is cleaned the clean water of hole 26h ejection along piston 20 to nozzle.Thereby this is because make the revolving force of cleaning water increase the cause of the hypotelorism of rotating flow by increasing the flow velocity of cleaning water.Thus, the clean enlarged areas of piston 20.Consequently, can fully guarantee the hygienic state of buttocks nozzle 1 and lady's hip bath nozzle 2.

In embodiment 3, preferably will be adjusted to about 5～15m/s from the flow velocity that nozzle is cleaned the clean water of hole 26h ejection.This occasion is cleaned water and is rotated preferably at the outer peripheral face of piston 20.Thus, produce the self-excited vibration of piston 20.

As mentioned above, nozzle is cleaned with nozzle 30 and is cleaned in the annulus between tube 26,26c and the piston 20 by cleaning the water distributing nozzle, just can carry out the clean, simple in structure of buttocks nozzle 1 and lady's hip bath nozzle 2, can realize saving the space.

In addition, as mentioned above, the internal diameter that nozzle is cleaned tube 26,26c is bigger than the external diameter of the piston 20 that forms circular, 20b, so distributing nozzle is cleaned the space-efficient ground rotation of clean water between the clean tube 26 of nozzle, 26c and piston 20,20b of hole 26h, 26hb.Consequently, the outer peripheral face of buttocks nozzle 1 and lady's hip bath nozzle 2 is cleaned at large.

In the above in the narration, in order to produce self-excited vibration, more than the preferably about 0.7mm in aperture of the clean hole 26h of nozzle and below about 1.0mm, do into about more than the 0.7mm and below about 1.0mm by the aperture of nozzle being cleaned hole 26h, even clean flow and be about lower 0.5L/min, also can obtain clean fully effect with high flow velocity.

Figure 38 is the ideograph that the structure of the leading section of clean tube 26 of explanation nozzle and piston 20 is used.

Shown in Figure 38 (a), the front end of piston 20 is given prominence to (scope of arrow H1) a little at the front end from the clean tube 26 of nozzle when cylinder body 21 is taken in.

Like this, the front end that the front end by piston 20 is cleaned tube 26 from nozzle is outstanding, thereby the clean water that can prevent to clean tube 26 inner ejections to nozzle are cleaned a upper face side of tins 26 to nozzle when front end flows out and dispersed.This phenomenon obtains according to wall attachment effect.

Wall attachment effect is meant that when being placed with object in the fluid that flows fluid can be along the mobile character of this object.Promptly, because the front end that the roughly hemispheric front end of piston 20 is cleaned tube 26 from nozzle is outstanding, so in the rotation of the outer peripheral face helically of piston 20 and clean clean water that tube 26 front ends flow out from nozzle and can not disperse, and flow out along the front end of piston 20 towards the upper face side that nozzle is cleaned tube 26.

The leading section that nozzle is cleaned tube 26 and piston 20 also can have the structure shown in Figure 38 (b).In Figure 38 (b), be provided with the breach NV of specific length (arrow H2) at the leading section upper face side of the clean tube 26 of nozzle.In addition, the front end of piston 20 nozzle of the breach NV front end outstanding (scope of arrow H1) a little of cleaning tube 26 never.

This occasion, is cleaned flowing of clean water that the inwall of tube 26 flows along nozzle at the clean water by flowing along the leading section of piston 20, and the clean water of cleaning hole 26h ejection from nozzle is more effectively flowed out from the leading section below that nozzle is cleaned tube 26.Therefore, can prevent to clean water reliably cleans from nozzle and cleans the upper face side that water cleans tube 26 to nozzle when tube 26 front ends flow out and disperse.Be located at nozzle clean tube 26 the leading section upper face side breach NV the length of circumferencial direction preferably nozzle clean the pact of circumference of tube 26 about half.

And the leading section that nozzle is cleaned tube 26 and piston 20 also can have the structure shown in Figure 38 (c).

In Figure 38 (c), gate SH can be installed in the leading section upper face side that nozzle is cleaned tube 26 up and down rotationally by pin Pi.When piston 20 was outstanding towards the direction of arrow G 1, gate SH rotated towards the direction of arrow G 2.

If adopt gate SH, disperse even clean the leading section upper face side that clean water that tube 26 front ends flow out cleans tube 26 to nozzle from nozzle, also can make the clean water adhesion that disperses on gate SH and fall.Thus, can prevent reliably that the clean water of cleaning the outflow of tube 26 front ends from nozzle from dispersing to the leading section upper face side of the clean tube 26 of nozzle.

Moreover, here gate SH is described, but be not limited thereto, get final product so long as can prevent a member that disperses of cleaning the clean water that tube 26 front ends flow out from nozzle, also can replace gate SH on nozzle cleans tins 26 or above plate etc. is set disperses and prevent wall.

Abovely the nozzle of buttocks nozzle 1 is cleaned tube 26 and nozzle is cleaned the shape of hole 26h and the self-excited vibration of piston 20 is illustrated according to Figure 36～Figure 38, but in lady's hip bath nozzle 2, nozzle cleans tube 26c and the clean hole 26hb of nozzle also has same shape, and piston 20 produces identical self-excited vibration.

Clean water inlet 24a is arranged on the eccentric position with respect to the central axis of cylinder body portion 21, so the clean water that flows into temperature change buffer part 28 refluxes into vortex shape shown in arrow V.The part of the clean water of temperature change buffer part 28 flows through the minim gap between the inner peripheral surface of the outer peripheral face of retainer 26a, 26b of piston portion 20 and cylinder body portion 21, flow out from the minim gap between the inner peripheral surface of the peristome 21a of the outer peripheral face of piston portion 20 and cylinder body portion 21, flow through the 1st runner 27e of piston portion 20 simultaneously and supply with cylindric volute chamber 29, ejection is arranged slightly from hole portion 25.The details of cylindric volute chamber 29 will be narrated in the back.

When piston portion 20 was advanced further, then shown in Figure 50 (c), retainer 26a, 26b contacted with stop surface 21c, the 21b water-stop of cylinder body portion 21 by seal washer 22a, 22b.Thus, the runner of the minim gap between the inner peripheral surface of the peristome 21a of outer peripheral face from the minim gap between the inner peripheral surface of the outer peripheral face of retainer 26a, the 26b of piston portion 20 and cylinder body portion 21 to piston portion 20 and cylinder body portion 21 is cut off.And the 2nd runner 27f that flows through piston portion 20 from the clean water of cleaning water inlet 24b supply supplies with cylindric volute chamber 29.Thus, the clean water that the 2nd runner 27f that flows through piston portion 20 supplies with cylindric volute chamber 29 mixes with the clean water that the 1st runner 27e that flows through piston portion 20 supplies with, and sprays from hole portion 25.

Like this, the 1st runner 27e and the 2nd runner 27f that clean water inlet 24a, the 24b of the clean water of being supplied with by clean water out 143c, the 143d of transfer valve 14 by cylinder body portion 21 flows through in the piston portion 20 import in the cylindric volute chamber 29, and flow through cylindric volute chamber 29 from squit hole 25 ejections.

Figure 51 is the ideograph of leading section of the piston portion 20 of Figure 49.Figure when the leading section of piston portion 20 is seen in Figure 51 (a) expression from above, the figure the when leading section of piston portion 20 is seen in Figure 51 (b) expression from the side.

At first, shown in Figure 51 (b), the 1st runner 27e is connected with the periphery of cylindric volute chamber 29 cylindraceous, and the 2nd runner 27f is connected with the bottom surface of cylindric volute chamber 29.Clean water from clean water out 143c, the 143d of transfer valve 14 is supplied with the 1st runner 27e and the 2nd runner 27f.

Shown in Figure 51 (a), the clean water of supplying with cylindric volute chamber 29 from the 1st runner 27e flows with the vorticity shown in the arrow Z owing to the curve form of the inner peripheral surface of cylindric volute chamber 29.On the other hand, the clean water of supplying with cylindric volute chamber 29 from the 2nd runner 27f flows to vertical direction with linear state.

Like this, in cylindric volute chamber 29, the clean water of the vorticity of the 1st runner 27e mixes with the clean water of the linearity of the 2nd runner 27f, cleans water from squit hole 25 ejections.

For example, the flow of the clean water of supplying with from the 2nd runner 27f when the flow-rate ratio of the clean water of supplying with from the 1st runner 27e for a long time, the clean water that mixes in cylindric volute chamber 29 is kept the vorticity that the curve form owing to cylindric volute chamber 29 cylindraceous forms strongly, so shown in the arrow H of Figure 51 (b), spray as the dispersion rotating flow with big angle.When the user presses ejection form dispersion by-pass cock 3021, then clean water as mentioned above as disperseing the rotating flow ejection.

And the flow of the clean water of being supplied with by the 1st runner 27e when the flow-rate ratio of the clean water of being supplied with by the 2nd runner 27f for a long time, the clean water that mixes in cylindric volute chamber 29 is kept linear state strongly, so shown in the arrow S of Figure 51 (b), spray as linear flow with narrow angle.When user's push ejection form is concentrated by-pass cock 302k, then clean water as mentioned above and spray as linear flow.

Therefore, control, the flow-rate ratio of cleaning water out 143c, 143d is changed, change thereby can make from the ejection form of the clean water of squit hole 25 ejections by the motor 141 of 4 pairs of transfer valves 14 of control part.

In embodiment 6, after pressing flow of water by-pass cock 302g, then the flow of the clean water out 143d of the flow-rate ratio of clean water out 143c is big, and the ejection form of cleaning water is near linear flow.And after pressing flow of water by-pass cock 302h, then the flow of the clean water out 143c of the flow-rate ratio of clean water out 143d is big, and the ejection form of cleaning water is near disperseing rotating flow.

Then, the ejection form to the clean water of embodiment 6 describes.In embodiment 6, buttocks nozzle 1 moves with various ejection forms between position and the rear position forwardly by motor 15 and sprays clean water on one side.
