Description

Water discharge device

Technical field

The present invention relates to a kind of water discharge device.

Background technology

Require to improve clean sense for cleaning the water discharge device of human body.Clean sense is the excitement when the water contact human body spuing from water discharge device and measures the sensation of sense left and right.If the characteristic by excitement and amount sense cover for the water that spued, excitement is the physical quantity of the flow velocity representative of water, and amount sense is the physical quantity of area (being also equivalent to be about to contact the basal area of the water before the human body) representative of the water of contact human body.In other words, excitement is the stimulus intensity of the water that user feels corresponding to the flow velocity of water, if the flow velocity of water accelerates, and excitement grow, if the flow velocity of water is slack-off, excitement dies down.In addition, amount sense be user feels corresponding to the area of the water of contact human body the water yield number, if the area of water broadens, amount sense grow, if the area of water narrows down, amount sense dies down.

On the other hand, also require water discharge device further to improve water-saving performance.Want to improve water-saving performance, must reduce the water yield spuing from water discharge device, if but merely reducing the water yield spuing, reducing amount sense, likely increases and entertains discontented user to cleaning sense.

So, following technology has been proposed, by continuous wire guttation being changed into the water body of interruption, thereby in low wash water, guarantee to encounter the area of the water of human body, not reducing amount sense.As an example of this technology, the technology that following patent documentation 1 is recorded has been proposed.In the technology of recording at following patent documentation 1, the jet velocity that forms alternately guttation is first and the slower second portion of jet velocity faster, by making first catch up with second portion before water contact human body, thereby forms larger water body.In the technology of recording at following patent documentation 1, in order to form such speed difference, utilized by applying discontinuously and comparing higher pressure for the feed pressure of water discharge device and change significantly the technology that guttation is pressed.By changing significantly in this wise guttation, press, thereby on guttation, produce the flow velocity change being interrupted, therefore realized the guttation that utilizes interruption water body as above.

Although the technology that following patent documentation 1 is recorded is for positively realizing the outstanding technology of utilizing the guttation that is interrupted water body, need to be than relatively large pump higher than the pressure of feed pressure in order to apply.If need the technology of the relatively large pump of such ratio, water discharge device integral body becomes the device of high price, the maximization that also likely brings device.

As not using pump, the technology of periodic variation guttation flow velocity has proposed the technology that following patent documentation 2 is recorded.In following patent documentation 2, by sneak into bubble in guttation, cause that the flow velocity of guttation changes.According to the record of the document, in the more parts of air capacity of sneaking into as bubble in washing water, the speed of the washing water of its part becomes faster.On the other hand, in the air capacity of sneaking into as bubble in washing water part still less, the speed of the washing water of its part becomes slower.Thus, in guttation, repeatedly produce part and low speed part at a high speed.

Patent documentation 1: the JP 2001-90151 of Japan communique

Patent documentation 2: No. 4572999 communique of Japan's patent

The technology that above-mentioned patent documentation 2 is recorded is can not use pump and the technology that causes the flow velocity change of guttation, sneaks into and produces flow velocity and change, thereby improved water-saving result simultaneously and cleaned sense by utilizing because of bubble.But, the self-criticism of being undertaken by the present inventors, has distinguished following content, and technology that above-mentioned patent documentation 2 is recorded is attainable is the sneaking into of minute bubbles of small diameter, also little because of the flow velocity change that sneaking into of such smaller bubble produces, its result can not form larger water body.More specifically, because flow velocity change is less, so till the guttation of speed partly catches up with slow water-discharge portion and divide, time that need to be longer, till the human body in water contact as object, likely there is the situation of the insufficient growth of water body.

Summary of the invention

The present invention carries out in view of such problem, object is to provide a kind of water discharge device, and it does not use mammoth pump, can make guttation produce enough large flow velocity change, even in the situation that guttation is till the distance of contact water is shorter, also can form enough large water body.

In order to solve above-mentioned problem, water discharge device involved in the present invention is the water discharge device of the water that spues towards human body, and it possesses: give water route, for feedwater; Jet, penetrates side spray from the described water of supplying with to water route as jet flow and downstream; The stream that spues, is arranged on the downstream of described jet, is provided with the discharge opening of the described jet flow that spues to outside; Water storage chamber, be arranged on described jet and described in spue between stream, have from described jet to described in the path passed through of the jet flow that spues till stream be water flowing path portion and be adjacent to the water portion that described water flowing path portion is used to form water; And bubble feed unit, when forming in described water portion air is made to the bubble of blister, to described water flowing path, portion supplies with this bubble.Bubble feed unit of the present invention is, there is the air introducing port that imports air to described water portion, by the air importing to from described air introducing port in described water portion, in the connected state maintaining with described air introducing port, along with the process of time, grow into significantly blister, at this bubble, become the stage that basal area is larger than the stream basal area of described jet, as air pocket, be supplied to discontinuously the unit of described water flowing path portion, and, alternatively repeatedly produce the first streamflow regime and the second streamflow regime, the first streamflow regime is, at the air importing from described air introducing port, become air pocket and till being supplied to described water flowing path portion, in described water portion, form the state of secondary current of the lower flow velocity of the connected state that can maintain described air introducing port and bubble, the second streamflow regime is, if the air importing from described air introducing port becomes air pocket and is supplied to described water flowing path portion, in described water portion, form and can cut off from described air introducing port the state of secondary current of the ratio high flow velocities of bubble.

According to the present invention, under the first streamflow regime, owing to forming the secondary current of the lower flow velocity of the connected state that can maintain air introducing port and bubble in water portion, therefore can not tear up by the formed bubble of air importing from air introducing port, can make bubble growth.On the other hand, under the second streamflow regime, if the air importing from air introducing port becomes air pocket and is supplied to water flowing path portion, in water portion, form and can cut off from air introducing port the secondary current of the ratio high flow velocities of bubble, therefore can be breaking at the bubble of growing up under the first streamflow regime, as air pocket, be supplied to water flowing path portion.By alternatively repeatedly producing the first such streamflow regime and the second streamflow regime, thus can alternatively repeatedly produce not to jet flow supply with air pocket during with to jet flow, supply with air pocket during.To jet flow, supply with air pocket during in, in the velocity ratio jet flow that spues under state faster.On the other hand, to jet flow, do not supply with air pocket during in, jet flow spues under the slow state of speed.Thereby, by alternatively repeatedly producing the first streamflow regime and the second streamflow regime, thereby can change significantly the speed of the jet flow being spued, make guttation produce larger flow velocity change, even if in the situation that from guttation till the distance of contact water is shorter, also can form enough large water body.

In addition in water discharge device involved in the present invention, also preferred, in described water portion, be provided with the spigot surface of the promotion bubble growth extending from water flowing path portion side described in described air introducing port side direction, described bubble feed unit is when keeping contacting the state of described spigot surface by the formed bubble of air importing from described air introducing port, till bubble is directed near the portion of described water flowing path.

The border of air and water is that gas-liquid interface is as follows, due to because of air and water respectively interactional equilibrium of forces form, therefore easily distortion, if lose equilibrium of forces, gas-liquid interface also can destroy.Thereby,, between the growth stage of bubble under the first streamflow regime, in order to make bubble stabilizes, grow up, need to keep the area of the gas-liquid interface that air contacts with water as far as possible littlely.So, under this preferred configuration, by keeping the state of the formed bubble contact of the air by importing from air introducing port spigot surface, thereby reduce the area of the gas-liquid interface from air introducing port side to water flowing path portion side, air introducing port and the connected state that becomes the bubble in long-distance can be maintained, stable bubble growth can be promoted.

In addition in water discharge device involved in the present invention, also preferred, described bubble feed unit is as follows, the secondary current of utilization under described the first streamflow regime, till being directed near the portion of described water flowing path when the formed bubble of air by importing from described air introducing port is pressed on described spigot surface.

In water storage chamber, owing to spraying jet flow from jet towards discharge opening, therefore produce and have negative pressure.Because this suction function is in the bubble forming in water storage chamber, so bubble likely bears the power of pulling open from spigot surface.So, under this preferred configuration, owing to by the secondary current under the first streamflow regime, bubble being pressed towards spigot surface, even therefore under suction function, bubble can not pull open from spigot surface yet, the area of the gas-liquid interface of minimizing from air introducing port side to water flowing path portion side, can maintain air introducing port and the connected state that becomes the bubble in long-distance, can promote stable bubble growth.

In addition in water discharge device involved in the present invention, also preferred, described bubble feed unit is as follows, the secondary current of utilization under described the first streamflow regime, by the formed bubble of air by importing from described air introducing port, till being directed near the portion of described water flowing path when the direction of the buoyancy to resistant function in this bubble is pressed.

Under this preferred configuration, owing to making to act on into buoyancy and the secondary current of the bubble in long-distance, reach balance, therefore can make bubble stabilizes and grow up, secondary current are to form resisting the mode of pressing bubble in the direction of this buoyancy.For example, even if the flow velocity of the secondary current under the first streamflow regime is high a little, also can reduce by the buoyancy of bubble secondary current and bubble be pressed on to the remainder of the power on spigot surface, therefore can get rid of the excessive impact being produced by secondary current, air introducing port and the connected state that becomes the bubble in long-distance can be maintained, stable bubble growth can be promoted.

In water discharge device involved in the present invention, also preferred in addition, described spigot surface has: first surface, press described bubble; And second, the 3rd, across described first surface, relatively configured.

Under this preferred configuration, due to first surface, second and the 3rd formation spigot surface, therefore the formed bubble of air by importing from air introducing port can be pressed on first surface, also can contact second and the 3rd simultaneously.Thereby, can reduce the area of the gas-liquid interface that secondary current contact with bubble, can maintain air introducing port and the connected state that becomes the bubble in long-distance, can promote stable bubble growth.

In water discharge device involved in the present invention, also preferred in addition, the secondary current introducing port that described secondary current form separately from being independent of described jet is directed in described water portion.

Under this preferred configuration, because the secondary current introducing port forming separately from being independent of jet imports secondary current, therefore compare as the situation of secondary current with the separated water importing from jet, by the flow control of secondary current, be easily lower speed.Thereby, can maintain air introducing port and the connected state that becomes the bubble in long-distance, can promote stable bubble growth.

In water discharge device involved in the present invention, also preferred in addition, described secondary current, under the state not interfering with described jet flow, press on the formed bubble of air by importing from described air introducing port described spigot surface.

Under this preferred configuration, under the state not interfering with jet flow, make secondary flow action in bubble, therefore secondary current can not be accelerated because of the effect of jet flow.Thereby, under the first streamflow regime, can there is not the exceedingly accelerated and situation of tearing up bubble of secondary current, can maintain air introducing port and the connected state that becomes the bubble in long-distance, can promote stable bubble growth.

In addition in water discharge device involved in the present invention, also preferred, the size of described air introducing port is configured to as follows, by the formed bubble of air importing from described air introducing port, be the size that can not be interrupted because of the secondary current under described the first streamflow regime with the connected state of described air introducing port.

When the first streamflow regime bubble is grown up, if bubble contacts with secondary current, bubble deforms.So, under this preferred configuration, owing to the size of air introducing port being set for to the connected state that can not be interrupted because of the secondary current under the first streamflow regime with air introducing port, therefore even if there is distortion because of the effect of secondary current in bubble, also air introducing port and the connected state that becomes the bubble in long-distance can be maintained, air pocket can be supplied with.

In water discharge device involved in the present invention, also preferred in addition, described spigot surface by connect swimmingly near described air introducing port with described jet near continuous surface form.

Under this preferred configuration, due to continuous surface smoothly, connect near air introducing port with jet near, till the air that therefore can make to import is fed into water flowing path portion, contact constantly spigot surface.

In water discharge device involved in the present invention, also preferred in addition, along the direction of described air introducing port opening, be provided with described spigot surface.

Under this preferred configuration, because the direction along air introducing port opening is provided with spigot surface, therefore the air importing from air introducing port is easy to grow up when maintenance is connected in the state of air introducing port, can suppress tearing up of air pocket, can form air pocket.

In water discharge device involved in the present invention, also preferred in addition, described air introducing port is as follows, from described water flowing path portion isolation, and is arranged on the upstream side in the direction of advance of described jet flow.

In water discharge device involved in the present invention, because jet flow and secondary current form rotating flow in water portion.Because jet flow flow velocity is higher than secondary current, so jet flow becomes large to the impact of the direction of rotation of rotating flow.Jet flow is injected and flow to discharge opening from jet, so the direction of rotation of rotating flow also follows jet flow, in abutting connection with jet flow, rotates.Because rotating flow is accelerated because flow to the jet flow of discharge opening from jet, so its flow velocity becomes the highest near the discharge opening accelerate finishing, and its flow velocity is in rotating on water portion and become minimum near the jet that accelerates to start.Under this preferred configuration, in order to utilize the characteristic of the VELOCITY DISTRIBUTION of this rotating flow, therefore the configuration of air introducing port is studied.The jet side being configured in the direction of advance of jet flow due to this air introducing port is upstream side, in the region that therefore becomes minimum to the flow velocity of rotating flow, imports air, can grow into air pocket.In addition, by from water flowing path portion air-isolation introducing port, the distance till can fully guaranteeing from air introducing port to water flowing path portion, can make air pocket fully grow up.

According to the present invention, a kind of water discharge device can be provided, it does not use mammoth pump, can make guttation produce enough large flow velocity change, even if in the situation that guttation, till the distance of contact water is shorter, also can form enough large water body.

To embodiments of the present invention, be that water discharge device describes.Water discharge device involved in the present invention is that it does not use mammoth pump, can make guttation produce enough large flow velocity change towards the spue device of water of human body, even if in the situation that guttation, till to contact the distance of water shorter, also can form enough large water body.Thereby the range of application of water discharge device involved in the present invention relates to many-side, can make agglomerating guttation contact human body, can be applicable to all simultaneously raising in water-saving result and the clean device of feeling.In description of the present embodiment, an example of having applied water discharge device of the present invention as the device that body local is cleaned is described.In view of purport of the present invention, as water discharge device involved in the present invention, be not limited to this.

As shown in Figure 1, the device for washing private parts WA as the related water discharge device of embodiments of the present invention is placed on the upper device using of lavatory pan CB.Device for washing private parts WA possesses body WAa, toilet seat WAb, toilet cover WAc and remote controller WAd.Body WAa has nozzle NZ, keeps nozzle NZ free to advance or retreatly.Body WAa rotates and keeps freely toilet seat WAb and toilet cover WAc.

User rotates toilet cover WAc in use as illustrated in fig. 1 upward, and toilet seat WAb is exposed.User from being formed at the discharge opening NZa guttation nozzle NZ, cleans the part of self by remote controller WAd after being sitting in the upper convenience of toilet seat WAb.User, after part is cleaned, stops the guttation from discharge opening NZa by remote controller WAd.Afterwards, user passes through remote controller WAd to lavatory pan CB swash of wave washing water.

In the present embodiment, as shown in Figure 1, set along the J axle of the direction of advance of guttation JW and V axle along plummet direction, use this J axle and V axle to describe the guttation form of device for washing private parts WA.

Fig. 2 represents an example of guttation initial velocity change in the present embodiment.

As shown in Figure 2, by periodic variation guttation initial velocity, thereby from the lower state of guttation initial velocity (FW of Fig. 2) to till higher state (FA of Fig. 2), during being formed with and making follow-up guttation catch up with catching up with of guttation in advance.Between during recurrent catching up with, due to be helpless to guttation that water body forms during, during being therefore referred to as easily in the present embodiment to waste water.

The guttation state of device for washing private parts WA shown in Fig. 3 modal representation Fig. 1.In the present embodiment, do not use mammoth pump, the flow velocity of periodic variation guttation, forms larger water body to impact the mode at guttation object position.

As shown in Fig. 3 (A), if the flow velocity change of the water spuing like this, guttation JW comprises position Wp1, Wp2, Wp3, Wp4, Wp5.When using the flow velocity separately of this each several part as V1, V2, V3, V4, V5, become V1(≈ V5) < V2(≈ V4) < V3.

Thereby, follow after guttation immediately (A)～(C) transition to Fig. 3, because the speed of position Wp3 is greater than position Wp2, so Wp3Yu position, position Wp2 is fit, and fit and become larger water body with position Wp1.

Due to the position Wp3 of Peak Flow Rate in this wise successively with its before position Wp2, position Wp1 fit, therefore become larger water body, contact body local.This washing water is, when encountering body local, in the larger water body state of impact energy (cleaning intensity).Because the flow velocity V3 of this position Wp3 is Peak Flow Rate, the washing water therefore spuing with stream of pulses is as follows, and under the guttation form occurring in each pulse period at the state of fit water body, from discharge opening, NZa spues.And, owing to producing such phenomenon in the pulse period, therefore the fit water body that repeatedly occurs passing through as described above the position Wp3 of Peak Flow Rate, the speed roughly the same through certain guttation water body constantly and the fit water body of the position Wp3 in the next guttation moment is spued.In addition, this each water body is in the state being connected with the position Wp3 of maximal rate by delaying position Wp4, the position Wp5 spuing.

The related device for washing private parts WA of present embodiment is, do not use mammoth pump and changes guttation flow velocity, utilizes the device of the guttation of the water body repeatedly periodically occurring as above.Device for washing private parts WA has water storage chamber 10 at the upstream side of the discharge opening NZa of the nozzle NZ shown in Fig. 1.The related device for washing private parts WA of present embodiment is by utilizing water storage chamber 10 to supply with the flow velocity that bubbles change guttation.The formation of this water storage chamber 10 is described with reference to Fig. 4.Fig. 4 is the figure of the general formation of modal representation water storage chamber 10.

As shown in Figure 4, water storage chamber 10 possesses air pipe line 101, the first supply line 102(to water route), pipeline 103, the second supply line 104 spue.Air pipe line 101, the first supply line 102, spue pipeline 103 and the second supply line 104 are pipelines of being arranged to be communicated in water storage chamber 10 inside.

The integral body of water storage chamber 10 is roughly cube-shaped casing shape.Water storage chamber 10 has wall 10e, wall 10f, wall 10g, wall 10h, wall 10i, wall 10j.Only on Fig. 4, depict as and form rectangle by wall 10e, wall 10f, wall 10g, wall 10h.Wall 10i and wall 10j are configured in mutually relative locational wall, in the mode of connecting wall 10e, wall 10f, wall 10g, wall 10h, are configured.

The first supply line 102 is the pipelines that connect jet 10b and water-supply source.The first supply line 102 is in the way of its pipeline or jet 10b place undergauge.Thereby, improve from the speed of the water of the first supply line 102 supplies, using this water as jet flow WSm to the interior injection of water storage chamber 10.

The pipeline 103 that spues is connect water storage chamber side opening 10c and be formed on nozzle NZ(with reference to Fig. 1) on the pipeline of discharge opening NZa.The in the situation that of present embodiment, jet 10b is configured by relative with water storage chamber side opening 10c.Thereby the jet flow WSm from jet 10b to water storage chamber 10 interior injections, advances in water storage chamber 10 along J axle, from water storage chamber side opening 10c, enter and spue pipeline 103.Enter the water spuing in pipeline 103 and advance in the pipeline 103 that spues along J axle, from the discharge opening NZa outside that spues.

The second supply line 104 is pipelines of auxiliary connection current introducing port 10d and water-supply source.The second supply line 104 is communicated in water storage chamber 10 inside by secondary current introducing port 10d.At least a portion of the water of supplying with from the second supply line 104 is secondary current WSs at the interior formation rotating flow of water storage chamber 10.

As mentioned above, the jet flow WSm from jet 10b to water storage chamber 10 interior injections, advances in water storage chamber 10 along J axle, from water storage chamber side opening 10c, enters and spues pipeline 103.Thereby the path that the jet flow WSm of formation from jet 10b to discharge opening NZa passes through is water flowing path portion 105.The in the situation that of present embodiment, water flowing path portion 105 is the paths that connect jet 10b and water storage chamber side opening 10c.

The remaining area except water flowing path portion 105 in water storage chamber 10 becomes water portion 106.Water portion 106 is for form the part of water PW in abutting connection with water flowing path portion 105.The in the situation that of present embodiment, water portion 106 forms to surround the mode of water flowing path portion 105.

The in the situation that of present embodiment, jet 10b and water storage chamber side opening 10c are in abutting connection with an avris that is configured in rectangular water storage chamber 10.On the other hand, air introducing port 10a and secondary current introducing port 10d are in abutting connection with another avris that is configured in rectangular water storage chamber 10.Thereby, isolation configuration jet 10b and water storage chamber side opening 10c and air introducing port 10a and secondary current introducing port 10d.

Fig. 5 means the figure of the A-A section of Fig. 4.Fig. 6 means the figure of the B-B section of Fig. 4.Under the state shown in Fig. 4, jet flow WSm advances in water PW, while the resistance bearing as illustrated in fig. 5 from water PW flows to water storage chamber side opening 10c.The jet flow WSm that arrives water storage chamber side opening 10c enters and spues in pipeline 103, under the state contacting as illustrated in fig. 6, advances at the internal face with the pipeline 103 that spues.

Under the state shown in Fig. 4, bubble BA is less.If again through after a while, bubble BA grows into elongate as illustrated in fig. 7 from the state shown in Fig. 4.Bubble BA grow to its lower end near jet flow WSm till.Thereby secondary current WSs compares narrower with the state shown in Fig. 4 in rotatable region.The rotary speed of secondary current WSs accelerates, and rotates up not hindering the mobile side of jet flow WSm.Fig. 8 and Fig. 9 be the C-C section of presentation graphs 7 and the D region of Fig. 7 respectively.

As shown in Figure 8,3 wall 10h, 10i in the middle of the bubble BA of elongate contact 4 wall 10h, 10i, 10j, 10f, 10j and grow up, 4 wall 10h, 10i, 10j, 10f extend towards jet 10b from the air introducing port 10a of water storage chamber 10.Thereby, only towards the face Contact Pair current WSs of secondary current introducing port 10d.

As shown in Figure 9, plummet direction is the bubble BA that the axial buoyancy of V is grown up in elongate.Secondary current WSs acts on bubble BA to resist the mode of this buoyancy.Thereby bubble BA can keep in touch 3 wall 10h, 10i in the middle of 4 wall 10h, 10i, 10j, 10f, the state of 10j, 4 wall 10h, 10i, 10j, 10f extend towards jet 10b from the air introducing port 10a of water storage chamber 10.

From the bubble BA of elongate this viewpoint of growing up, wall 10h, 10i, 10j are as bubble BA is directed to the spigot surface of water flowing path portion 105 and brings into play function from air introducing port 10a.Secondary current WSs produces the power of pressing bubble BA towards wall 10h, 10i, 10j, as the pressing force applying unit performance function that bubble BA elongate is grown up, so that bubble BA is not isolated from spigot surface, is wall 10h, 10i, 10j.Be preferably as follows in the present embodiment formation, the length of the spigot surface from air introducing port 10a side to water flowing path portion 105 sides is longer than the length of the water flowing path portion 105 from jet 10b to water storage chamber side opening 10c.

Because secondary current WSs is rotating flow and produces centrifugal force towards wall 10h, therefore produce and actively bubble BA is pressed on to the effect on wall 10h.But if do not produce external effect, bubble BA direct expansion and subglobular, even if therefore do not produce the effect of actively pressing, also can adopt the form of bringing into play function as pressing force applying unit.Figure 10 represents variation from the above point of view.

As shown in figure 10, in water storage chamber 10, be provided with wall 10k.Wall 10k is configured between wall 10h and wall 10f and is roughly parallel to each wall.To be isolated from the mode of wall 10g and wall 10e, configure wall 10k.Wall 10k is arranged on to the position that is also isolated from water flowing path portion 105.

By wall 10k is set in this wise, thereby the bubble BA importing from air introducing port 10a advances between wall 10h and wall 10k, towards water flowing path portion 105, grows up.Although wall 10k actively presses bubble BA towards wall 10h, owing to suppressing the expansion of bubble BA, so produce the power of pressing towards wall 10h in result, as pressing force applying unit, bring into play function.

Although bringing into play the wall 10h of function as spigot surface is the straight wall along the upwardly extending plane in side with wall 10g, wall 10e quadrature, but in order to bring into play the function as spigot surface, so long as connect swimmingly near near continuous surface air introducing port 10a and jet 10b.With reference to Figure 11 and Figure 12, the variation from this viewpoint is described.

Water storage chamber 10B shown in Figure 11 has wall 10e, wall 10Bf, wall 10Bg, wall 10Bh.Air introducing port 10a is arranged on wall 10Bg.Air introducing port 10a is arranged on roughly near the corresponding position central authorities with wall 10e.Due to wall 10Bh connect near air introducing port 10a with jet 10b near, be therefore obliquely installed as illustrated in fig. 11.Even if be obliquely installed in this wise wall 10Bh, also, because the direction along air introducing port 10a opening (towards the direction of jet 10b) tilts, therefore performance is as the function of the spigot surface that bubble BA is grown up.

Water storage chamber 10C shown in Figure 12 has wall 10e, wall 10Cf, wall 10Cg, wall 10Ch.The wall 10Ch of water storage chamber 10C is the shape towards outside curve.Even like this crooked wall 10Ch, also due to connect swimmingly near air introducing port 10a with jet 10b near, therefore performance is as the function of the spigot surface that bubble BA is grown up.

The variation of the allocation position that changes air introducing port is described with reference to Figure 13.Water storage chamber 10D shown in Figure 13 has wall 10e, wall 10Df, wall 10Dg, wall 10Dh.Air introducing port 10Da is wall 10Df and the bight that wall 10Dg docks, and is arranged on wall 10Df.As shown in figure 13, due to the bight that is formed with wall 10Dg and docks with wall 10Dh, therefore the wall from air introducing port 10Da to jet 10b is not continuous swimmingly, forms discontinuous.In the case, although also bring into play deficiently the function as above-mentioned spigot surface, can form the bubble BA of elongate.

If again through after a while, the bubble BA of elongate approaches jet flow WSm and starts to interfere as illustrated in fig. 14 from the state shown in Fig. 7.Bubble BA is pulled by jet flow WSm, enters water flowing path portion 105.Thereby, entering bubble BA squeezed the moving back of water partly, the rotation flow velocity of secondary current WSs accelerates.The secondary current WSs that rotation flow velocity improves tears up bubble BA.

If again through after a while, bubble BA is introduced in jet flow WSm completely as illustrated in fig. 15 from the state shown in Figure 14, in the roughly universe of water flowing path portion 105, there is bubble BA.Figure 16 and Figure 17 represent respectively the F region of Figure 15 and the E-E section of Figure 15.

As shown in Figure 16 (A), owing to having bubble BA in the roughly universe in water flowing path portion 105, till being therefore present near jet 10b.Thereby, be present near the discharge reduction of jet 10b, be suppressed near the eddy current that produces of jet 10b.In the situation that bubble BA is formed at the position of leaving jet 10b, become the state as shown in Figure 16 (B).Under the state as shown in Figure 16 (B), water is more present near jet 10b, more produces eddy current.Because eddy current produces, become the resistance that jet flow WSm advances, therefore by suppress eddy current as shown in Figure 16 (A), thereby can not reduce the speed of jet flow WSm and make it flow to discharge opening NZa.

As shown in figure 17, jet flow WSm break-through bubble BA.Due to jet flow WSm break-through bubble BA in this wise, so jet flow WSm resistance around reduces, and can not reduce the speed of jet flow WSm and makes it flow to discharge opening NZa.But, not necessarily need the state of the complete break-through bubble of the jet flow WSm BA as Figure 17 is illustrated, as long as can enough bubble BA surround jet flow WSm around compared with many parts, also can be in contacting the state of water PW in a part.

If again through after a while, bubble BA flows to the pipeline 103 that spues as in being introduced in jet flow WSm as shown in figure 18 from the state shown in Figure 15.The mode that is larger stream basal area due to bubble BA to compare with water flowing path portion 105 forms, while being therefore hampered by water storage chamber side opening 10c periphery flows to the pipeline 103 that spues.The bubble BA that is hampered by this wise water storage chamber side opening 10c periphery, because of jet flow, WSm is pressed into from rear, is bearing from the pressure of water PW and the bulged-in while enters and spues in pipeline 103.

If again through after a while, bubble BA enters and spues in pipeline 103 as illustrated in fig. 19 from the state shown in Figure 18.Figure 20 represents the G-G section of Figure 19.As shown in figure 20, if bubble BA enters in the pipeline 103 that spues, the inwall along the pipeline 103 that spues forms air film, and jet flow WSm advances in this film.Thereby, the drag reduction of the inwall from the pipeline 103 that spues that jet flow WSm bears, jet flow WSm does not slow down and flows to discharge opening NZa.But, not necessarily need the state as bubble BA encases jet flow WSm completely as illustrated in Figure 15, as long as can be enough bubble BA surround jet flow WSm around compared with many parts, also can be in contacting the state of the pipeline 103 that spues in a part.

If also advanced to the downstream of the pipeline 103 that spues from the state bubble BA shown in Figure 19, next bubble BA enters from air pipe line 101, turns back to the state of Fig. 4.In the present embodiment, periodically repeatedly there is the variation of the bubble Ba that describes with reference to Fig. 4～Figure 20.

In addition in the present embodiment, the time point that arrives water flowing path portion 105 from the air pocket BA first generating, till the air pocket BA next generating arrives the second time of the time point of water flowing path portion 105, be longer than the time point that arrives water flowing path portion 105 from the air pocket BA of first generation, till the very first time of the time point that the integral body of the air pocket BA of this arrival is discharged from water flowing path portion 105.

Like this, because the second time was longer than the very first time, therefore the time point that the air pocket BA first generating is arrived to water flowing path portion 105, as benchmark, arrives the time point of water flowing path portion 105 at the air pocket BA next generating, one makes the air pocket BA first generating discharge from water flowing path portion 105 surely.Thereby, can positively produce water-filled the second water flowing state of water flowing path portion 105.

In addition in the present embodiment, be provided with: air introducing port 10a, is directed to water flowing path portion 105 by secondary current WSs by air pocket BA, to the interior importing air of water storage chamber 10; And wall 10h, 10i, 10j, become and by secondary current WSs, from air introducing port 10a, be directed to the spigot surface of the resistance unit of the resistance that the air pocket BA of water flowing path portion 105 moves, as bubble BA is directed to the spigot surface of water flowing path portion 105 and brings into play function from air introducing port 10a.

In order to guarantee more longways the second above-mentioned time, need as far as possible lentamente the air supply importing from air introducing port 10a to water flowing path portion 105.But owing to being subject to the impact of jet flow WSm to produce secondary current WSs in water storage chamber 10, so air pocket BA is directed to water flowing path portion 105 by secondary current WSs.Thus, exist air pocket BA to compare the situation that is earlier directed to water flowing path portion 105 with the moment of imagination, also supposed to realize completely the situation of the second water flowing state.So under this preferred configuration, by being set to be directed to because of secondary current the resistance unit of resistance of the air pocket BA of water flowing path portion 105, it is spigot surface, thereby moderately adjust the translational speed of air pocket BA, positively produce water-filled the second water flowing state of water flowing path portion 105.

In addition in the present embodiment, owing to when being to press air pocket BA on wall 10h, 10i, 10j to spigot surface, air pocket BA being directed to water flowing path portion 105, therefore can utilize the frictional force producing between spigot surface and air pocket BA, adjust continuously the translational speed of air pocket BA till from air introducing port 10a side to water flowing path portion 105.

In addition in the present embodiment, owing to utilizing secondary current WSs, to spigot surface, be on wall 10h, 10i, 10j, to press air pocket BA, therefore do not need to arrange other to the unit of pressing air pocket BA on spigot surface, can positively adjust the translational speed of air pocket BA.

In addition in the present embodiment, due to continuous surface smoothly, connect near air introducing port 10a with jet 10b near, therefore can more positively maintain the state of air pocket BA contact spigot surface.

In addition in the present embodiment, owing to maintaining the connected state of air pocket BA and air introducing port 10a, so air pocket BA and the secondary current WSs part place beyond the part of this connection contacts, and the contact area of air pocket BA and secondary current WSs diminishes.Thereby, owing to can reducing air pocket BA, move to the speed of water flowing path portion 105, so can positively produce water-filled the second water flowing state of water flowing path portion 105.

Figure 21 represents that actual fabrication is equivalent to the water storage chamber 10 of present embodiment the photograph that the situation of water flowing is taken.Figure 21 (A) is the photograph that jet flow WSm is advanced and grown up and have the state of bubble BA to take in water PW, is equivalent to the state of Fig. 7.Figure 21 (B) is to the jet flow WSm photograph that forward travel state is taken in bubble BA, is equivalent to the state of Figure 14.Figure 21 (C) is to the jet flow WSm photograph that forward travel state is taken in bubble BA, is equivalent to the state of Figure 18.

As mentioned above, the related water discharge device of present embodiment is device for washing private parts WA, is that it possesses towards the device of human body guttation: the first supply line 102, for the water route of giving of feedwater; Jet 10b, using the water of supplying with from the first supply line 102 as jet flow WSm and downstream side spray is penetrated; Discharge opening NZa, is arranged on the downstream of jet 10b, the jet flow that spues to outside WSm; Water storage chamber 10, is arranged between jet 10b and discharge opening NZa, has from jet 10b till the path that the jet flow WSm of discharge opening NZa passes through is water flowing path portion 105 and is adjacent to the water portion 106 that water flowing path portion 105 is used to form water PW; And air introducing port 10a, at least a portion function of bubble feed unit of air being made to the bubble BA of blister is supplied with in performance to water flowing path portion 105.

When interior from jet 10b observation water storage chamber 10, bubble feed unit generates the air pocket BA(of stream basal area that basal area is greater than jet 10b with reference to Figure 17), by forming discontinuously this air pocket BA, thereby the first water flowing state (with reference to Figure 15) alternatively repeatedly producing in jet flow WSm break-through air pocket BA passes through the second water flowing state (with reference to Fig. 4, Fig. 7) in water with jet flow WSm, changes the water flowing resistance of the jet flow WSm in water flowing path portion 105.

In the present embodiment, owing to forming discontinuously basal area, be greater than the air pocket BA of the stream basal area of jet 10b, so the first water flowing state and the jet flow WSm that can alternatively repeatedly produce in jet flow WSm break-through air pocket BA pass through the second water flowing state in water.Under the first water flowing state, in jet flow WSm break-through air pocket BA, therefore at jet flow WSm, there is more air around, reduce the hollow of resistance of jet flow WSm speed, jet flow WSm maintenance speed flows to discharge opening NZa.On the other hand, under the second water flowing state, because jet flow WSm is by water, so by water, surrounded around jet flow WSm, reduce the resistance grow of jet flow WSm speed, jet flow WSm underspeeds and flows to discharge opening NZa.Thereby, by alternatively repeatedly producing the first water flowing state and the second water flowing state, thereby can change significantly the speed of the jet flow WSm that flows to discharge opening NZa, make guttation produce larger flow velocity change, even if in the situation that from guttation till the distance of contact water is shorter, also can form enough large water body.

In addition in the present embodiment, the jet flow WSm being retracted is from jet 10b ejection, to make the basal area of jet flow WSm be less than the basal area of air pocket BA.Like this, because the jet flow WSm being retracted is from jet 10b ejection, so the diffusion of jet flow WSm is suppressed, can positively control its basal area.Thereby, due to the state that can positively form the basal area of jet flow WSm and become the basal area that is less than air pocket BA, can positively realize the first water flowing state, therefore can make guttation produce larger flow velocity change.

In addition in the present embodiment, the jet 10b of bubble feed unit deflection water flowing path portion 105 supplies with air pocket BA.Like this, due to the jet 10b supply air pocket BA of deflection water flowing path portion 105, so the jet flow WSm of break-through is to long this air pocket BA of discharge opening NZa layback.Thereby, by kine bias, to jet 10b, supplying with the so easy method of air pocket BA, can make to exist in the longer scope of air pocket BA till from jet 10b side to discharge opening NZa side.Its result, the length of the jet flow of break-through air pocket BA is elongated, can more positively avoid the deceleration of the jet flow WSm under the first water flowing state, owing to can positively realizing the first water flowing state, therefore can make guttation produce larger flow velocity change.

In addition in the present embodiment, bubble feed unit is supplied with air pocket BA(with reference to Figure 16 to cover the mode of jet 10b).Like this, by supplying with air pocket BA to cover the mode of jet 10b, thereby can enough air cover jet 10b near.Thereby, under the first water flowing state, be suppressed at jet 10b and around produce eddy current, can suppress to follow the disorder of the jet flow WSm that eddy current produces.Its result, advances because jet flow WSm is stable, can positively realize the first water flowing state, therefore can make guttation produce larger flow velocity change.

In addition in the present embodiment, be provided with for introduce the air introducing port 10a of air to water storage chamber 10 from outside, near air introducing port 10a, be provided with as the internal face (with reference to Fig. 8) that promotes the water storage chamber 10 of the spigot surface that bubble BA grows up, it extends towards water flowing path portion 105 sides from air introducing port 10a side simultaneously.

The air being incorporated in water storage chamber 10 from air introducing port 10a has following tendency, before becoming air pocket BA because the current in water storage chamber 10 pull open and tear up from air introducing port 10a.So the blister air of introducing from air introducing port 10a, supports owing to being set up the nigh internal face as spigot surface, even if therefore bear water Potential, also stably promoted to grow up, can positively grow into air pocket BA.Thereby, owing to can positively realizing the first water flowing state, therefore can make guttation produce larger flow velocity change.

In addition, the bubble feed unit of present embodiment is in the interior generation basal area of the pipeline 103 that spues, to be greater than the unit of air pocket BA of the stream basal area of jet 10b, by forming discontinuously this air pocket BA, thereby alternatively repeatedly produce jet flow WSm by the first water flowing state (with reference to Figure 20) in the air layer forming along the internal face of the pipeline 103 that spues because of air pocket BA, with jet flow WSm by be supplied to the second water flowing state (with reference to Fig. 6) in the water spuing pipeline 103 from water storage chamber 10, change the contact area of the water being flowing in the pipeline 103 that spues and pipeline 103 internal faces that spue.

According to this viewpoint, because forming the air pocket BA being supplied to that basal area is greater than the stream basal area of jet 10b discontinuously, bubble feed unit spues in pipeline 103, therefore can alternatively repeatedly produce jet flow WSm by the first water flowing state in the air layer of the internal face formation along the pipeline 103 that spues, and jet flow WSm is by being supplied to the second water flowing state in the water spuing pipeline 103 from water storage chamber 10.Under the first water flowing state, because jet flow WSm is by being formed in the air layer in the pipeline 103 that spues, the internal face of pipeline 103 and the contact area of jet flow WSm of therefore spuing diminishes, and the frictional force that the jet flow WSm advancing in the pipeline 103 that spues bears diminishes.On the other hand, under the second water flowing state, because jet flow WSm is by the water of supplying with from water storage chamber 10, the internal face of the pipeline 103 that therefore spues becomes large with the contact area that comprises the water of jet flow WSm, and it is large that the frictional force that the jet flow WSm advancing in the pipeline 103 that spues bears becomes.Thereby, by alternatively repeatedly producing the first water flowing state and the second water flowing state, thereby change the contact area with the internal face of the pipeline 103 that spues at the interior mobile water of the pipeline 103 that spues.By the change of this frictional force, can change significantly the speed of the jet flow WSm that flows to discharge opening NZa, make guttation produce larger flow velocity change, even if in the situation that from guttation till the distance of contact water is shorter, also can form enough large water body.

And, under the first water flowing state, because jet flow WSm is by being formed in the air layer in the pipeline 103 that spues, if flowing of the water integral body in the pipeline 103 that is therefore conceived to spue compared actual stream basal area with the second water flowing state and more reduced.Thereby the speed that becomes under the first water flowing state the jet flow WSm by the pipeline 103 that spues is higher than an essential factor of the speed of the water by the pipeline 103 that spues under the second water flowing state.On the basis of the flow velocity change of the foregoing guttation causing because of the change of frictional force, also append the flow velocity change effect of the guttation that the change because of stream basal area causes, thereby can make guttation produce larger flow velocity change.

In addition in the present embodiment, bubble feed unit forms following tubulose air layer by generating air pocket BA, and the mode that tubulose air layer surrounds by the jet flow WSm in the pipeline 103 that spues with the direction of advance along jet flow WSm forms along internal face.Like this, the tubulose air layer because formation is extended on internal face along the mode of the direction of advance encirclement jet flow WSm of jet flow WSm, therefore can further reduce jet flow WSm and the contact area of the internal face of the pipeline 103 that spues.Thereby, can compare the speed that improves more fully the jet flow WSm under the first water flowing state with the speed of water under the second water flowing state, can make guttation produce larger flow velocity change.

In addition in the present embodiment, bubble feed unit is from water flowing path portion 105 to the pipeline 103 of spuing, to supply with the unit of air pocket BA, to cover the opening towards water storage chamber 10 of the pipeline 103 that spues, is that the mode of water storage chamber side opening 10c periphery is supplied with air pocket BA.

Like this, owing to being that the mode of water storage chamber side opening 10c periphery is supplied with air pocket BA from water flowing path portion 105 sides to cover the opening towards water storage chamber 10 of the pipeline 103 that spues, therefore can send into air pocket BA in the mode of the internal face along the pipeline 103 that spues.Thereby, easily form along the tubulose air layer of the internal face of the pipeline 103 that spues, can make guttation produce larger flow velocity change.

In addition in the present embodiment, bubble feed unit is from water flowing path portion 105 to the pipeline 103 that spues, to supply with the unit of air pocket BA, in the situation that observing water flowing path portion 105 side from pipeline 103 sides that spue, supply with the air pocket BA that basal area is greater than the stream basal area of the pipeline 103 that spues.

Like this, owing to supplying with basal area, be greater than the air pocket BA of the stream basal area of the pipeline 103 that spues, so can positively along the internal face of the pipeline 103 that spues, send into air pocket BA.Thereby, easily form along the tubulose air layer of the internal face of the pipeline 103 that spues, can make guttation produce larger flow velocity change.

In addition in the present embodiment, bubble feed unit, when supplying with air pocket BA from water flowing path portion 105 to the pipeline 103 that spues, temporarily makes to supply with after its delay.Like this, when supplying with air pocket BA from water flowing path portion 105 to the pipeline 103 of spuing, after temporarily making it be detained, supply with, therefore easily make air pocket BA press close to spue on the internal face of pipeline 103.Thereby, more really and easily form along the tubulose air layer of the internal face of the pipeline 103 that spues, can make guttation produce larger flow velocity change.

In addition in the present embodiment, bubble feed unit is preferably as follows, and to form same length, in the mode of the air layer of the length of the direction of advance along jet flow WSm of the pipeline 103 that spues, generates and supply with air pocket BA.Therefore under this preferred configuration, owing to supplying with air pocket BA to form the mode of air layer in the span of pipeline 103 total lengths that spues, form tubulose air layer till can be from water storage chamber 10 to discharge opening NZa.Thereby under the first water flowing state, the frictional force that can make jet flow WSm bear till from water storage chamber 10 to discharge opening NZa is minimum, can make guttation produce larger flow velocity change.

In addition in the present embodiment, the mode being positioned at the central axis of the jet flow WSm that sprays from jet 10b the roughly same straight line of central axis of the pipeline 103 that spues configures jet 10b and spues pipeline 103, and the mode that is greater than the stream basal area of jet 10b with the stream basal area of the pipeline 103 that spues forms.

Like this, owing to configuring the central axis of the jet flow WSm spraying from jet 10b to be positioned at mode on the roughly same straight line of central axis of the pipeline 103 that spues, therefore can make spue pipeline 103 center and the center-aligned of charging into the jet flow WSm in pipeline 103 that spues.And, because the stream basal area with jet 10b is compared larger the stream basal area that is formed with the pipeline 103 that spues, therefore can positively keep the gap between jet flow WSm and the internal face of the pipeline 103 that spues.Thereby, can in this gap, form tubulose air layer, can positively make jet flow WSm by tubulose air layer.

In addition, the bubble feed unit of present embodiment is through Growing, to be larger blister by the air and the time that import to from air introducing port 10a in water storage chamber 10, and the stage that becomes prescribed level at this bubble BA is supplied to the unit of water flowing path portion 105 as air pocket BA, and, at the air importing from air introducing port 10a, become air pocket BA and till being supplied to water flowing path portion 105, alternatively repeatedly produce the first streamflow regime (with reference to Fig. 4, Fig. 7) with the second streamflow regime (with reference to Figure 14), the first streamflow regime is, in the interior formation of water portion 10, can maintain the state of secondary current WSs of lower flow velocity of the connected state of air introducing port 10a and bubble BA, the second streamflow regime is, with the air importing from air introducing port 10a, become air pocket BA and the mode that is supplied to water flowing path portion 105 can be cut off from air introducing port 10a the state of secondary current WSs of the ratio high flow velocities of bubble BA in the interior formation of water portion 10.

According to this viewpoint, under the first streamflow regime, owing to can maintain the secondary current WSs of lower flow velocity of the connected state of air introducing port 10a and bubble BA in the interior formation of water portion 10, therefore can not tear up by the formed bubble BA of air importing from air introducing port 10a, can make bubble BA grow up.On the other hand, under the second streamflow regime, with the air importing from air introducing port 10a, become air pocket BA and the mode that is supplied to water flowing path portion 105 can be cut off from air introducing port 10a the secondary current WSs of the ratio high flow velocities of bubble BA in the interior formation of water storage chamber 10, therefore can be breaking at the bubble BA growing up under the first streamflow regime, as air pocket BA, be supplied to water flowing path portion 105.By alternatively repeatedly producing the first such streamflow regime and the second streamflow regime, thus can alternatively repeatedly produce not to jet flow WSm supply with air pocket BA during with to jet flow WSm, supply with air pocket BA during.During jet flow WSm supply air pocket BA, jet flow WSm maintenance speed flows to discharge opening NZa.On the other hand, to jet flow WSm, do not supply with air pocket BA during in, jet flow WSm flows to discharge opening NZa when underspeeding.Thereby, by alternatively repeatedly producing the first streamflow regime and the second streamflow regime, thereby can change significantly the speed of the jet flow WSm that flows to discharge opening NZa, make guttation produce larger flow velocity change, even if in the situation that from guttation till the distance of contact water is shorter, also can form enough large water body.

In addition in the present embodiment, in water storage chamber 10, be provided with and from air introducing port 10a side towards water flowing path portion 105 sides, extend and bring into play as promoting the spigot surface that bubble BA grows up the inwall of the water storage chamber 10 of function, bubble feed unit is in the formed bubble BA contact of air that keeps making importing from air introducing port 10a in the state as the inwall of spigot surface, bubble BA is directed near water flowing path portion 105 till (with reference to Fig. 7 and Fig. 8).

The border of air and water is that gas-liquid interface is as follows, due to because of air and water respectively interactional equilibrium of forces form, therefore easily distortion, if lose equilibrium of forces, gas-liquid interface also can destroy.Thereby, during making that bubble BA grows up under the first streamflow regime, for bubble BA is stably grown up, need to keep the area of the gas-liquid interface that air contacts with water as far as possible littlely.So, by keeping the state using the formed bubble BA contact of the air by importing from air introducing port 10a as the inwall of spigot surface, thereby reduce the area of the gas-liquid interface from air introducing port 10a side to water flowing path portion 105 sides, air introducing port 10a and the connected state that becomes the bubble BA in long-distance can be maintained, stable bubble growth can be promoted.

In addition in the present embodiment, bubble feed unit is as follows, the secondary current WSs of utilization under the first streamflow regime, be directed to water flowing path portion 105 when the formed bubble BA of air by importing from air introducing port presses on as the inwall of spigot surface near till (with reference to Fig. 7 and Fig. 9).

In water storage chamber 10, owing to spraying jet flow WSm from jet 10b towards discharge opening NZa, therefore produce and have negative pressure.Because this suction function is in the bubble BA in water storage chamber 10 interior formation, thus bubble BA likely to bear from spigot surface be the power that wall pulls open.So, because the secondary current WSs by under the first streamflow regime presses bubble BA towards the wall as spigot surface, even therefore under suction function, bubble BA can not pull open from the wall as spigot surface yet, the area of the gas-liquid interface of minimizing from air introducing port 10a side to water flowing path portion 105 sides, air introducing port 10a and the connected state that becomes the bubble BA in long-distance can be maintained, stable bubble growth can be promoted.

In addition in the present embodiment, bubble feed unit is as follows, the secondary current WSs of utilization under the first streamflow regime, by the formed bubble BA of air by importing from air introducing port 10a, be directed near water flowing path portion 105 when the direction of the buoyancy of this bubble BA is pressed to resistant function till (with reference to Fig. 9).

Like this, owing to making to act on into buoyancy and the secondary current WSs of the bubble BA in long-distance, reach balance, therefore can make bubble BA stably grow up, secondary current WSs is to form resisting the mode of pressing bubble BA in the direction of this buoyancy.For example, even if the flow velocity of the secondary current WSs under the first streamflow regime is high a little, also can reduce by the buoyancy of bubble BA secondary current WSs bubble BA is pressed on to the remainder of the power on the wall of spigot surface, therefore can get rid of the excessive impact being produced by secondary current WSs, air introducing port 10a and the connected state that becomes the bubble BA in long-distance can be maintained, stable bubble growth can be promoted.

In addition in the present embodiment, spigot surface has: first surface, press bubble; And second, the 3rd, across first surface, relatively configured (with reference to Fig. 8).Like this, due to first surface, second and the 3rd formation spigot surface, therefore the formed bubble BA of air by importing from air introducing port 10a can be pressed on first surface, also can contact second and the 3rd simultaneously.Thereby, can reduce the area of the gas-liquid interface that secondary current WSs contacts with bubble BA, can maintain air introducing port 10a and the connected state that becomes the bubble BA in long-distance, can promote stable bubble growth.

In embodiment, the secondary current introducing port 10d that described secondary current form separately from being independent of jet 10b is directed in water storage chamber 10 in addition.Like this.Because the secondary current introducing port 10d forming separately from being independent of jet 10b imports secondary current WSs, therefore compare as the situation of secondary current WSs with the separated water importing from jet 10b, by the flow control of secondary current WSs, be easily lower speed.Thereby, can maintain air introducing port 10a and the connected state that becomes the bubble BA in long-distance, can promote stable bubble growth.

In addition in embodiment, secondary current WSs, under the state not interfering with jet flow WSm, presses on the formed bubble BA of air by importing from air introducing port 10a spigot surface.Like this, under the state not interfering with jet flow WSm, make secondary current WSs act on bubble BA, therefore secondary current WSs can not be accelerated because of the effect of jet flow WSm.Thereby, under the first streamflow regime, can there is not the exceedingly accelerated and situation of tearing up bubble BA of secondary current WSs, can maintain air introducing port 10a and the connected state that becomes the bubble BA in long-distance, can promote stable bubble growth.

In addition in the present embodiment, the size of air introducing port 10a is configured to as follows, by the formed bubble BA of air importing from air introducing port 10a, be the size that can not be interrupted because of the secondary current WSs under the first streamflow regime with the connected state of air introducing port 10a.

When the first streamflow regime bubble is grown up, if bubble BA contacts with secondary current WSs, bubble BA deforms.So, owing to the size of air introducing port 10a being set for to the connected state that can not be interrupted because of the secondary current WSs under the first streamflow regime with air introducing port 10a, therefore even if there is distortion because of the effect of secondary current WSs in bubble BA, also air introducing port 10a and the connected state that becomes the bubble BA in long-distance can be maintained, air pocket BA can be supplied with.

In addition, when interior from jet 10b observation water storage chamber 10, the bubble feed unit of present embodiment generates the air pocket BA that basal area is greater than the stream basal area of jet 10b, by forming discontinuously this air pocket BA and being supplied to water flowing path portion 105, thereby alternatively repeatedly produce, jet flow WSm is pressurizeed and the first state that makes its acceleration and the second state that does not make jet flow WSm accelerate.

According to this viewpoint, because bubble feed unit forms the air pocket BA that basal area is greater than the stream basal area of jet 10b discontinuously, therefore can alternatively repeatedly produce jet flow WSm is pressurizeed and makes the first state of its acceleration and do not make the second fluid jet assisted state.Under the first state, due to jet flow WSm is pressurizeed, make it accelerate, so jet flow WSm flow to discharge opening NZa in speed-raising.On the other hand, under the second state, owing to not making jet flow WSm accelerate, so jet flow WSm does not gather way and flows to discharge opening NZa.Thereby, by alternatively repeatedly producing the first state and the second state, thereby the speed that can change significantly the jet flow WSm that flows to discharge opening NZa makes guttation produce larger flow velocity change, even in the situation that shorter to the distance of contact water from guttation, also can form enough large water body.

In addition in the present embodiment, under the first state, by jet flow WSm, from being supplied to the upstream side of the air pocket BA of water flowing path portion 105, air pocket BA is pressurizeed, this pressurized air pocket BA pressurizes to the jet flow WSm in downstream and makes it accelerate (with reference to Figure 18).Like this, because the air pocket BA being pressurizeed by jet flow WSm also pressurizes to the jet flow WSm in downstream, therefore under the first state, jet flow WSm is further accelerated, and the speed that can change significantly jet flow WSm makes guttation produce larger flow velocity change.

In addition in the present embodiment, under the first state, when the air pocket BA that is supplied to water flowing path portion 105 discharges from discharge opening NZa, the jet flow WSm spuing from discharge opening NZa is pressurizeed and makes its acceleration.Like this, when the air pocket BA that is supplied to water flowing path portion 105 discharges from discharge opening NZa, because utilization opens at the power that atmosphere blows out, the jet flow WSm spuing from discharge opening NZa is pressurizeed, and make its acceleration, therefore under the first state, jet flow WSm is further accelerated, and the speed that can change significantly jet flow WSm makes guttation produce larger flow velocity change.

In addition in the present embodiment, under the first state, when the air pocket BA that is supplied to water flowing path portion 105 discharges towards discharge opening NZa, to be the big or small mode of the water storage chamber side opening 10c that covers the pipeline 103 that spues from water storage chamber 10 towards discharge opening NZa, supply with air pocket BA.

Like this, due to when discharging from water storage chamber 10 towards discharge opening NZa, the big or small mode that covers water storage chamber side opening 10c to be is supplied with air pocket BA, so air pocket BA do not bear resistance and discharge, but is discharged from the resistance temporarily bearing from water storage chamber side opening 10c.Thereby in this process, air pocket BA bears the pressure from jet flow WSm, the internal pressure of air pocket BA uprises.Its result, under the first state, jet flow WSm bears from the larger pressure of air pocket BA and is accelerated, and the speed that can change significantly jet flow WSm makes guttation produce larger flow velocity change.

In above-mentioned present embodiment, although be independent of jet 10b in order to form secondary current WSs, secondary current introducing port 10d is set separately, preferably secondary current introducing port 10d is not set yet and forms the form of secondary current WSs.With reference to Figure 22 and Figure 23, variation is from this viewpoint described.

Figure 22 means as the water storage chamber 10L figure that forms the variation of secondary current WSs in water storage chamber 10.Figure 23 is the figure of differentiation of the type of flow of the secondary current WSs for illustrating in the variation shown in Figure 22.

Water storage chamber 10L omits the secondary current introducing port 10d of water storage chamber 10 and jet 10b is carried out to hole enlargement and as the member of jet 10bL.By forming the jet 10bL that carries out in this wise hole enlargement, thereby a part of jet flow WSm turns, and forms the secondary current WSs as shunting WSd.

As shown in Figure 23 (A), in the less stage of bubble BA, because the pressure in water storage chamber 10L is lower, the shunt volume of therefore shunting WSd is many, and it is many that the flow of secondary current WSs also becomes.On the other hand, as shown in Figure 23 (B), large if bubble BA becomes, the pressure in water storage chamber 10L uprises, and the shunt volume of shunting WSd reduces, and the flow of secondary current WSs reduces.

Figure 24 means as the figure of water storage chamber 10M that forms the variation of secondary current WSs in water storage chamber 10.Water storage chamber 10M is the member that omits the secondary current introducing port 10d of water storage chamber 10 and be provided with undergauge member 10cM to seal the mode of a part of water storage chamber side opening 10c.By adopting such structure, thereby a part of jet flow WSm is because undergauge member 10cM turns, and forms the secondary current WSs as shunting WSd.

Figure 25 means and in water storage chamber, is provided with the figure that discharges the water storage chamber 10Ma of the undergauge member 10cMa that suppresses unit as air pocket.Water storage chamber 10Ma is the member that omits the secondary current introducing port 10d of water storage chamber 10 and be provided with undergauge member 10cMa to seal the mode of a part of water storage chamber side opening 10c.By adopting such structure, thereby can utilize the simple structure the basal area that is less than air pocket BA as the stream basal area that makes water storage chamber side opening 10c to realize air pocket discharge inhibition unit, therefore can make air pocket BA be centered around jet flow WSm around by simple structure.

In addition, the jet flow WSm spraying from jet 10b is not or not undergauge member 10cMa interferes and advances to discharge opening with inwall and the bubble discharge inhibition unit of water storage chamber 10Ma.

By adopting such structure, thereby can suppress jet flow WSm, exceedingly change direction of advance because of inwall and the undergauge member 10cM of water storage chamber 10Ma, in the guttation mouth side (water storage chamber side opening 10c side) of water flowing path portion 105, in water portion 106, produce larger flowing.Therefore, can suppress to be supplied to water flowing path portion 105 and because air pocket discharge suppress unit be the effect of undergauge member 10cMa and the air pocket BA adverse current of being detained to water portion 106, can contribute to produce alternately swimmingly the first water flowing state and the second water flowing state.

In such water storage chamber 10Ma, air pocket BA is supplied to the position of the jet 10b of deflection water flowing path portion 105, and undergauge member 10cMa makes air pocket BA temporarily be stranded in the member of the position of the guttation mouth (water storage chamber side opening 10c side) of being partial to water flowing path portion 105.

Like this, owing to air pocket BA being supplied to the position (with reference to Figure 25 (A)) of the jet 10b of deflection water flowing path portion 105, so this air pocket BA is elongated to discharge opening side (water storage chamber side opening 10c side) by the jet flow WSm spraying from jet 10b.Thereby, by kine bias, to jet 10b, supplying with the so easy method of air pocket BA, can make to exist in the longer scope of air pocket BA till from jet 10b side to discharge opening side (water storage chamber side opening 10c side).Its result, the length of the jet flow WSm of break-through air pocket BA is elongated, can more positively avoid the deceleration of the jet flow WSm under the first water flowing state, owing to can positively realizing the first water flowing state, therefore can make guttation produce larger flow velocity change.

And, owing to making air pocket BA temporarily be stranded in the position (with reference to Figure 25 (B)) of the guttation mouth (water storage chamber side opening 10c) of deflection water flowing path portion 105, the air pocket BA that is therefore supplied to water flowing path portion 105 stops when deflection guttation mouth (water storage chamber side opening 10c) is mobile.Therefore, there is not air pocket BA in the jet 10b that supply portion of air pocket BA is partial to water flowing path portion 105, even if the air pocket of next circulation is supplied to water flowing path portion 105, can suppress contact and be connected with the air pocket BA of circulation before yet.Therefore, can positively produce alternately the first water flowing state and the second water flowing state.

In the present embodiment, be used to form enough large water body obligato be the change that more positively causes water flowing resistance.Therefore, under the first water flowing state, till air pocket BA need to being configured in to position to the extremely close position of discharge opening (water storage chamber side opening 10c) of extremely close jet 10b.For example, in the situation that could not fully guarantee the length of water flowing path portion 105 or the flow velocity of jet flow WSm higher, also can suppose to be supplied to the air pocket BA of water flowing path portion 105 or could not be detained the sufficient time to form the degree of the first water flowing state.

So, be provided with as air pocket and discharge the undergauge member 10cMa that suppresses unit, its air pocket BA that suppresses to move along jet flow WSm around moves to discharge opening side (surpassing water storage chamber side opening 10c moves), and air pocket BA is temporarily trapped in around water flowing path portion 105.By air pocket is set in this wise, discharge to suppress unit, thereby the air pocket BA that is supplied to water flowing path portion 105 is not discharged from immediately and rests on around water flowing path portion 105.Therefore, air pocket BA is also easily centered around around jet flow WSm, can positively form jet flow WSm by the first water flowing state in air pocket BA, by alternatively producing the first water flowing state and the second water flowing state, thereby can positively make guttation produce flow velocity change.Like this, can the larger flow velocity of guttation generation be changed by changing significantly the speed of the jet flow that flows to discharge opening, even if in the situation that guttation, till the distance of contact water is shorter, also can form enough large water body.

Figure 26 means and in water storage chamber, is provided with the figure that discharges the water storage chamber 10Mb of the undergauge member 10cMb that suppresses unit as air pocket.Water storage chamber 10Mb is the member that omits the secondary current introducing port 10d of water storage chamber 10 and be provided with undergauge member 10cMb to seal the mode of a part of water storage chamber side opening 10c.By adopting such structure, thereby can utilize the simple structure the basal area that is less than air pocket BA as the stream basal area that makes water storage chamber side opening 10c to realize air pocket discharge inhibition unit, therefore can make by easy structure air pocket BA be centered around around jet flow WSm.

In addition, the jet flow WSm spraying from jet 10b is not or not undergauge member 10cMb interferes and advances to discharge opening with inwall and the air pocket discharge inhibition unit of water storage chamber 10Mb.

By adopting such structure, thereby can suppress jet flow WSm, exceedingly change direction of advance because of inwall and the undergauge member 10cMb of water storage chamber 10Mb, in the guttation mouth side (water storage chamber side opening 10c side) of water flowing path portion 105, in water portion 106, produce larger flowing.Therefore, can suppress to be supplied to water flowing path portion 105 and because air pocket discharge suppress unit be the effect of undergauge member 10cMb and the air pocket BA adverse current of being detained to water portion 106, can contribute to produce alternately swimmingly the first water flowing state and the second water flowing state.

In such water storage chamber 10Mb, air pocket BA is supplied to the position of the jet 10b of deflection water flowing path portion 105, and undergauge member 10cMb makes air pocket BA temporarily be stranded in the member of the position of the guttation mouth (water storage chamber side opening 10c side) of being partial to water flowing path portion 105.

Like this, owing to air pocket BA being supplied to the position (with reference to Figure 26 (A)) of the jet 10b of deflection water flowing path portion 105, so this air pocket BA is elongated to discharge opening side (water storage chamber side opening 10c side) by the jet flow WSm spraying from jet 10b.Thereby, by kine bias, to jet 10b, supplying with the so easy method of air pocket BA, can make in the longer scope till air pocket BA is present in from jet 10b side to discharge opening side (water storage chamber side opening 10c side).Its result, the length of the jet flow WSm of break-through air pocket BA is elongated, can more positively avoid the deceleration of the jet flow WSm under the first water flowing state, owing to can positively realizing the first water flowing state, therefore can make guttation produce larger flow velocity change.

And, owing to making air pocket BA temporarily be stranded in the position (with reference to Figure 26 (B)) of the guttation mouth (water storage chamber side opening 10c) of deflection water flowing path portion 105, the air pocket BA that is therefore supplied to water flowing path portion 105 stops when deflection guttation mouth (water storage chamber side opening 10c) is mobile.Therefore, owing to suppressing air pocket BA, move to discharge opening side, air pocket BA is long to jet 10b layback, therefore can be more positively to the end supply air pocket BA of the jet 10b side of water flowing path portion 105.

In the present embodiment, be used to form enough large water body obligato be the change that more positively causes water flowing resistance.Therefore, under the first water flowing state, till air pocket BA need to being configured in to position to the extremely close position of discharge opening (water storage chamber side opening 10c) of extremely close jet 10b.For example, in the situation that could not fully guarantee the length of water flowing path portion 105 or the flow velocity of jet flow WSm higher, also can suppose to be supplied to the air pocket BA of water flowing path portion 105 or could not be detained the sufficient time to form the degree of the first water flowing state.

So, be provided with as air pocket and discharge the undergauge member 10cMb that suppresses unit, its air pocket BA that suppresses to move along jet flow WSm around moves to discharge opening side (surpassing water storage chamber side opening 10c moves), and air pocket BA is temporarily trapped in around water flowing path portion 105.By air pocket is set in this wise, discharge to suppress unit, thereby the air pocket BA that is supplied to water flowing path portion 105 is not discharged from immediately and rests on around water flowing path portion 105.Therefore, air pocket BA is also easily centered around around jet flow WSm, can positively form jet flow WSm by the first water flowing state in air pocket BA, by alternatively producing the first water flowing state and the second water flowing state, thereby can positively make guttation produce flow velocity change.Like this, can the larger flow velocity of guttation generation be changed by changing significantly the speed of the jet flow that flows to discharge opening, even if in the situation that guttation, till the distance of contact water is shorter, also can form enough large water body.

And, near viewpoint air pocket BA being supplied to jet 10b, the also form of the water storage chamber 10S shown in preferred Figure 27.Water storage chamber 10S shown in Figure 27 is as follows, and wall 10eS, the wall 10fS, wall 10gS, the wall 10hS that delimit chamber are set, and wall 10hS is configured in to the upstream side of jet 10b.

From air pocket BA being positively supplied to the viewpoint of the jet 10b side end of water flowing path portion 105, by the spigot surface of air pocket BA, be preferably also the upstream side that water flowing path portion 105 side ends of wall 10hS are arranged on the jet 10b in jet flow WSm direction of advance in this wise.
