The cardinal extremity in gap 315 (upstream extremity) forms with buttocks cleaning runner 310 and is communicated with, and this gap 315 becomes ring-type along the peripheral shape that sprays runners 312.That is, in this first embodiment, gap 315 is also used as at least two opposed gaps that arrange in the mode that is communicated with buttocks cleaning runner 310 and the communication channel that arranges in the mode that is communicated with these at least two opposed gaps.In addition, pressure communication chamber 316 is communicated with the terminal (downstream) in gap 315, and forms ring-type.In addition, in this first embodiment, the volume 315 that pressure communication chamber 316 constitutes its volume ratio gap is big.
Thus, clean the high pressure that runner 310 puts on the privileged site of end difference 314 from buttocks and be passed to the position different with described privileged site (being opposed position at this) of end difference 314 via pressure communication road 317, can improve the pressure of this part.In addition, as described later, as long as pressure communication road 317 has at least two gaps that arrange in the mode that is communicated with buttocks cleaning runner 310 and the communication channel that arranges in the mode that is communicated with these at least two gaps, pressure communication road 317 can adopt various forms.
As shown in Figure 6, the women special-purpose clean runner 330 form from the rearward end of nozzle body 300 till near the leading section with the axle center almost parallel of the flow diameter of about 3.0～3.5mm and nozzle body 300 set.Clean being provided with of runner 330 midway and make flow diameter be contracted to damping hole 331 about φ 1.0～1.5mm in that the women is special-purpose, damping hole 331 leading sections are connected with the hydroecium 332 of the below that is provided in the special-purpose cleaning of women ejiction opening 340.Hydroecium 332 is connected with the special-purpose ejection of women runner 341.
The section area of hydroecium 332 is bigger than the section area of the special-purpose cleaning of women runner 330, and the front of this hydroecium 332 is formed by crooked upward flexure plane.Thus, reduce from the special-purpose rinse water flow velocity in hydroecium 332 that cleans runner 330 inflows of women, this rinse water flows into the special-purpose runner 341 that sprays of women along flexure plane under the state that the composition of beating that rinse water is had reduces.
The cardinal extremity of the special-purpose ejection of women runner 341 is connected with hydroecium 332, and the terminal of the special-purpose ejection of women runner 341 forms the special-purpose ejiction opening 340 that cleans of women.The cardinal extremity of the special-purpose ejection of women runner 341 forms the cylindric of the about 1.8mm of diameter, and the special-purpose ejection of women runner 341 forms taper (having formed the situation that reduces in the complete cycle scope).In addition, the special-purpose ejection of women runner 341 forms from it midway to terminal expansion (its section area increases).Thus, can make the smooth and easy and inflow stably of rinse water that flows into women's special use ejection runner 341 from hydroecium 332, and can spray the less rinse water of composition of beating from the special-purpose ejiction opening 340 that cleans of women.
＜4〉action of spray nozzle device and clean washing apparatus
The action of the spray nozzle device 100 that this first embodiment relates to and the clean washing apparatus 10 that possesses this spray nozzle device 100 then, is described referring to figs. 1 to Fig. 4.
At first, as shown in Figure 2, nozzle casing 400 is positioned at the rear portion of nozzle guide 111, and nozzle body 300 also is positioned at the rear portion of sliding scale.This position is called reception position, this state is called receiving state.At this moment, the special-purpose overlapping state of ejiction opening 340 that cleans of the ejection opening 411 that forms nozzle casing 400 and the women of nozzle body 300.
When beginning to clean from receiving state, at first, by operated the remote controller 60 of clean washing apparatus 10 by the user, the control member of main body 20 begins to control.In addition, make for the first time at the control member that clean washing apparatus 10 is arranged at toilet 70, main body 20 under the situation of spray nozzle device 100 actions, carry out the Position Control of nozzle casing 400 as described below.
That is, the control member of main body 20 drives CD-ROM drive motor 114.Like this, the rotation of CD-ROM drive motor 114 is passed to pinion 115 via a plurality of change-speed gearings, thus, makes the nozzle casing 400 with the tooth bar 421 that meshes with pinion 115 rearward to move.Yet nozzle casing 400 is positioned at reception position, therefore can't be further rearward mobile, thereby the invariant position of the fore-and-aft direction of nozzle casing 400.Therefore, the control member of main body 20 is stored as initial point with this position, and by detect the rotating speed of CD-ROM drive motor 114 with the rotating speed detecting sensor, infers the amount of movement of nozzle casing 400, thereby carry out the Position Control of nozzle casing 400.
Then, the control member of main body 20 makes CD-ROM drive motor 114 reverse rotations, makes nozzle casing 400 forwards mobile.At this moment, nozzle body 300 is drawn by nozzle casing 400 by coupling member 500, and forwards mobile under integrated state.
At this, under user's the situation that is operating as the special-purpose operation of cleaning of women, the control member of main body 20 when the rotating speed of CD-ROM drive motor 114 reaches setting value, stops CD-ROM drive motor 114 according to predefined control sequence (sequence).Thus, nozzle casing 400 and the nozzle body 300 that has forwards moved stops in predefined precalculated position.In addition, under this state, the special-purpose ejiction opening 340 that cleans of women is positioned at the substantial middle that sprays opening 411, and this position is the special-purpose cleaning positions of women.In addition, under this state, the special-purpose ejiction opening 340 that cleans of women can not blocked in the edge portion of ejection opening 411.
Then, control member control rinse water supply member supplies water to the special-purpose runner 330 that cleans of women, cleans thereby the beginning women is special-purpose.Eject by ejection opening 411 from the special-purpose rinse water of cleaning ejiction opening 340 ejections of women.In addition, cleaning the switching of runner and the adjusting of flow utilizes the rinse water supply member to carry out.
The rinse water of being supplied with by the rinse water supply member of beating that has flows into the special-purpose runner 330 that cleans of women via rinse water supply port 339, and flows into hydroecium 332 from the special-purpose runner 330 that cleans of women by damping hole 331.During this period, after by damping hole 331 backs and inflow hydroecium 332, the rinse water flow velocity reduces immediately, and rinse water generation eddy current, thus stirring and washing water.Thus, can reduce the pulsatory feeling of rinse water.
The rinse water that flows into the special-purpose ejection of women runner 341 from hydroecium 332 stably flows into based on the situation that arranges at the special-purpose base end part that sprays runner 341 of women.Flow into the special-purpose rinse water that sprays runner 341 of women and flow through the special-purpose ejection of this women runner 341, and spray from the special-purpose ejiction opening 340 that cleans of women.At this moment, because the special-purpose ejection of women runner 341 forms from it midway towards the terminal expansion, therefore can provide soft cleaning sense from the special-purpose ejiction opening 340 ejections few rinse water of composition of beating of cleaning of women.In addition, buttocks cleans ejiction opening 320 and is in the state that is covered by nozzle casing main body 410, can directly not contact the special-purpose sewage that produces that cleans by the women, therefore can keep clean.
Then, the women is special-purpose to be cleaned when stopping when the user operates, and the control member of main body 20 is rotated in the forward CD-ROM drive motor 114, makes nozzle casing 400 and nozzle body 300 rearward mobile, gets back to original reception position.
