In recess 30, because main flow Fw is flowed into recess 30, the current except forming the entrance 16 towards Drainage Division 18 Outside, the right side wall portions 30a (the first side wall portion) of collision recess 30 is also formed afterwards towards the current Dwf in front.Current Dwf After the right side wall portions 30a flowings along recess 30, flowed in a manner of colliding left side wall 30b.Current Dwf is due to collision The right side wall portions 30a, left side wall 30b of recess 30 impact, flowed in a manner of being elected while rising.The rising Current Dwf collaborates (with reference to scope with the current Dwc (2) flowed into from the front side received on face 26 towards rear side in recess 30 Sb), so as to forming the current Dwg of the entrance 16 towards Drainage Division 18.With current Dwc (2) equally, current Dwg is also with from horse Flowed towards the mode of rear side front side in bucket seat portion 14.

Illustrate the action effect of the water closet 10 of the above.

(1) according to water closet 10 above, in three cut zone in four cut zone Sr1~Sr4 respectively Form independent water jet 32A~32C.Therefore, with being formed in two cut zone in four cut zone Sr1~Sr4 Independent water jet is compared, and can be shortened from each water jet 32A~32C each in other adjacent eddy flow direction of rotation Da sprays The interior girth of edge part 28 untill the mouth of a river.Consider to assume the situation for being individually formed water jet in two cut zone.Along edge The flushing water of the inner peripheral surface flowing in portion 28 is wandered downwards under gravity.Therefore, in this case, due to from water jet to The interior girth of edge part 28 untill other water jets is elongated, therefore is difficult to rushing for arrival sufficient amount in the position away from water jet Wash water.On this point, according to present embodiment, it is because edge part 28 can shorten from water jet to other water jets on the whole The interior girth of edge part 28 only, therefore the inner peripheral surface for being easy to make flushing water reach edge part 28 is overall, can obtain good Rim wash ability.

(2) in addition, towards mainly being sprayed by the flushing water that is sprayed from the first water jet 32A and from the second water jet 32B Flushing water collaborates and forms the main flow Fw of the entrance 16 to Drainage Division 18.Because second water jet 32B is located at the 3rd point of front side Cut region Sr3, therefore compared with being arranged at the situation of rear side cut zone, flushing water can be shortened from the second water jet 32B The path of section flowing untill the entrance 16 of Drainage Division 18.As a result, by the flushing water sprayed from the second water jet 32B The main flow Fw of formation water slug becomes strong, and the dirt in closestool portions 14 is poured into Drainage Division 18 by the main flow Fw of strong water slug Entrance 16, so as to obtain good dirt discharging performance.

In addition, mainly pass through the flushing water sprayed from the first water jet 32A and the flushing water sprayed from the second water jet 32B Collaborate on face 26 is received on the inner peripheral surface of closestool portions 14 and form the main flow Fw of the entrance 16 towards Drainage Division 18.Cause This, can be rinsed by the main flow Fw of strong water slug and receive face 26, can obtained good toilet seat and rinse performance.

In addition, aspect of performance is rinsed obtaining good rim wash ability, dirt discharging performance, toilet seat, can also Consider that whole washing water quantity used in a closestool is rinsed in increase, or increase the aperture area of water jet and increase flushing water The method of spray volume.On this point, according to present embodiment, due to entirely being rinsed used in a closestool without increasing to rinse Water, thus can be obtained while preventing whole washing water quantity from increasing good rim wash ability, dirt discharging performance, Toilet seat rinses performance.Further, since the aperture area of water jet need not be increased, therefore the opening surface of water jet can prevented Good rim wash ability, dirt discharging performance, toilet seat are obtained while product increase and rinses performance.Especially, due to can Prevent the aperture area of water jet from increasing, therefore by reducing the size of water jet, can be obtained simultaneously obtaining good outward appearance Performance is rinsed to good rim wash ability, dirt discharging performance, toilet seat.

In addition, in terms of the inner peripheral surface entirety for making flushing water reach edge part 28, it is from a water jet to other water jets The interior girth of edge part 28 only is longer, more needs to increase the flushing water spray volume of a water jet, it is also necessary on this basis increase The size in the edge water guide path 34 being connected with a water jet greatly.On this point, according to present embodiment, and on edge part 28 The situation for forming two water jets is compared, and can shorten the inner circumferential of the edge part 28 from a water jet untill other water jets It is long.Therefore, in terms of the inner peripheral surface entirety for making flushing water reach edge part 28, it can reduce three water jet 32A~32C's On the basis of flushing water spray volume, the frame portion 34a in edge water guide path 34 width, standing wall portion 34b height etc. can be reduced Size.

In addition, water spray portion 36 is configured to after flushing water is sprayed from the first water jet 32A and the 3rd water jet 32C, from Second water jet 32B sprays flushing water, there is an advantage in that.When increase is to the whole flushing water that is acted for once flushing When the flow of main flow Fw for amount is the ratio of main flow flow, can be increased without whole washing water quantity just increases main flow flow Add, ability, toilet seat rinse capability are discharged so as to which dirt can be improved by the increase of main flow flow.According to present embodiment, Reduced, therefore can increased without collaborating just to flow into the washing water quantity of entrance 16 due to that can make to spray from the second water jet 32B Main flow flow relative to whole washing water quantity ratio.Therefore, it is increased without whole washing water quantity, it becomes possible to by increasing main flow The ratio of flow discharges ability, toilet seat rinse capability to improve dirt.

Then, other features related to the first water jet 32A~the 3rd water jet 32C are illustrated.

Water spray portion 36 is configured to, and the first water jet 32A flushing water spray volume is most, the second water jet 32B flushing water Spray volume time is more, and the 3rd water jet 32C flushing water spray volume is minimum.That is, with flushing water spray volume according to the first water jet The mode of 32A, the second water jet 32B and the 3rd water jet 32C order reduction is formed.From the point of view of another viewpoint, with the first spray Modes of the mouth of a river 32A compared with other two the second water jet 32B, the 3rd water jet 32C more than flushing water spray volume is formed.Here Flushing water spray volume refer to flushing water-carrying capacity (L/s) by the unit interval of water jet.

In order to meet the magnitude relationship of this each water jet 32A~32C flushing water spray volume, water spray portion 36 is with such as lower section Formula is formed.For from the inflow position Pa (reference picture 3) of the flushing water from flush water supply device to each water jet 32A~ Discuss in the water flowing path in water flowing portion 38 untill 32C.Assuming that water flowing path, which exists, corresponds respectively to the first water jet 32A ~the three water jet 32C water flowing path.The flushing water spray volume of water jet is the water flowing road with supplying flushing water to water jet The passage sections at the minimum position (hereinafter referred to as " flow set portion ") of passage sections product accumulate directly proportional size in footpath.In this reality Apply in mode, the first water jet 32A flow set portion is positioned at the first of the downstream in the first water jet 32A water flowing path Water jet 32A is in itself.Second water jet 32B flow set portion also for the second water jet 32B in itself, the 3rd water jet 32C's Flow set portion also for the 3rd water jet 32C in itself.

Water spray portion 36 is configured to, and the first water jet 32A passage sections product is that aperture area is maximum, the second water jet 32B Aperture area time it is big, the 3rd water jet 32C is minimum.That is, with aperture area according to the first water jet 32A, the second water jet 32B And the 3rd water jet 32C order reduce mode form.From the point of view of another viewpoint, with the first water jet 32A and other two Mode second water jet 32B, the 3rd water jet 32C big compared to aperture area is formed.Here aperture area (passage sections Product) refer to sectional area on the section orthogonal with water flowing direction.So as to be sprayed with each water jet 32A~32C each flushing water The magnitude relationship of amount and the magnitude relationship identical mode of each water jet 32A~32C each aperture area are formed.

Fig. 8 is the interior girth Lb1~Lb3 for each edge water guide path 34A~34C for showing edge part 28 figure.

Here interior girth refers to, in the horizontal cross-section by edge part 28, from positioned at each edge water guide path 34A~ Each water jet 32A~32C of 34C top position to each edge water guide path 34A~34C terminal location 34Aa~34Ca's The inner peripheral surface length of scope.For example, first edge water guide path 34A interior girth Lb1 is from the first water jet 32A to the first side The inner peripheral surface length of edge water guide path 34A terminal location 34Aa scope.

Edge part 28 is formed as, and first edge water guide path 34A interior girth Lb1 is most long, second edge water guide path 34B Interior girth Lb2 vice-minister, the 3rd edge water guide path 34C interior girth Lb3 is most short.That is, with according to interior girth Lb1, interior girth The mode that Lb2, interior girth Lb3 order shorten is formed.The ratio between these interior girth Lb1, Lb2, Lb3 are, for example, Lb1：Lb2：Lb3 =5：3：2.

Water spray portion 36 is configured to, the magnitude relationship of three water jet 32A~32C each flushing water spray volume and three sprays The edge water guide path 34C of mouth of a river 32A~32C each connected first edge water guide path 34A~the 3rd interior girth Lb1 ~Lb3 magnitude relationship is identical.For example, the first water jet that the first edge water guide path 34A most long with interior girth Lb1 is connected 32A flushing water spray volume is most.In addition, the 3rd water spray that the threeth edge water guide path 34C most short with interior girth Lb3 is connected Mouth 32C flushing water spray volume is minimum.

More specifically, water spray portion 36 is configured to, the ratio between three water jet 32A~32C each flushing water spray volume phase When in the edge water guide path of three water jet 32A~32C each be connected first edge water guide path 34A~the 3rd The ratio between 34C interior girth Lb1~Lb3.For example, it is 5 in the ratio between interior perimeter L b1~Lb3：3：In the case of 2, with three water jets The ratio between 32A~32C each flushing water spray volume is equivalent to 5：3：2 mode is formed.In addition, water spray portion 36 is configured to, three Each aperture area of the ratio between the water jet 32A~32C each flushing water spray volume equivalent to three water jet 32A~32C it The mode of ratio is formed.

According to foregoing feature, because the first water jet 32A flushing water spray volume is than other second water jets 32B, Three water jet 32C are more, therefore main flow is formed in closestool portions 14 easily by from the flushing water that the first water jet 32A sprays Fw.Therefore, by adjust each water jet 32A~32C position, flushing water emission direction etc., can be for closestool portions 14 The interior main flow Fw type of flow carries out various settings, it is possible to increase the free degree of the backwashing manner of flushing water.

In addition, it is same as and three water jets with the magnitude relationship of three water jet 32A~32C flushing water spray volume The magnitude relationship of the edge water guide path 34C of the first edge water guide path 34A that 32A~32C is connected~the 3rd interior girth Mode is formed.Therefore, it is possible to make the first edge water guide path 34A of girth length in more washing water quantity inflow, it is easy to make foot It is overall that the flushing water enough measured reaches first edge water guide path 34A.In addition, by making all length including less washing water quantity 3rd edge water guide path 34C flows, and can suppress the flushing water usage amount in the 3rd edge water guide path 34C.Therefore, make While the flushing water of sufficient amount reaches the inner peripheral surface entirety of edge part 28 and obtains good rim wash ability, it is easy to suppress The usage amount of the overall flushing water of inner peripheral surface for rinsing edge part 28.

Further, since after the first water jet 32A of the flushing water spray volume more than other two water jets 32B, 32C is arranged at First cut zone of side, there is an advantage in that.In order to increase the first water jet compared to other two water jets 32B, 32C 32A flushing water spray volume, it is necessary to ensure that to the right side water flowing path 38b of the first water jet 32A supply flushing waters and leads to than left side Passage sections product bigger water route 38c.According to present embodiment, due to by the first water jet 32A more than flushing water spray volume The cut zone of rear side is arranged at, therefore is cut compared to the situation for the cut zone that the first water jet 32A is arranged to front side, path The big right side water flowing path 38b of area anteroposterior dimension is inhibited, and is easy to minimize water spray portion 36.Therefore, it is possible to obtain Good rim wash ability, dirt discharge ability, toilet seat rinse capability while, be easy to make water spray portion 36 overall small-sized Change.

In addition, water spray portion 36 is configured to, the first water jet 32A and the second water jet 32B flushing water spray volume add up to Measure the flushing water spray volume that (hereinafter also referred to " total spray volume ") is more than the 3rd water jet 32C.Thus, it is possible to which expect will be relative The washing water quantity of more than half is used for main flow Fw formation for the whole washing water quantity acted for once flushing.Therefore, The main flow Fw of strong water slug flow can be increased, closestool portions 14 can be rinsed by the main flow Fw of strong water slug, big flow Reception face 26, and good toilet seat rinse capability can be obtained.In addition, pass through strong water slug, the main flow of big flow Fw pours the dirt in closestool portions 14 entrance 16 of Drainage Division 18, so as to obtain especially good dirt discharging performance.From From the viewpoint of obtaining this action effect, it is preferred that water spray portion 36 is with the first water jet 32A's and the second water jet 32B Total spray volume relative to once flushing act used in whole washing water quantity ratio be 60%~80% mode form. Here the total amount of the water jet 32C of whole washing water quantity and the first water jet 32A~the 3rd each flushing water spray volume is same Justice.

It is further preferred, that water spray portion 36 is acted with the first water jet 32A flushing water spray volume relative to once flushing The mode that the ratio of used whole washing water quantity is 40%~60% is formed.

Further illustrate other features on the water jet 32C of the first water jet 32A~the 3rd.

As shown in figure 3, the first water jet 32A~the 3rd water jet 32C be separately formed at the second of two front sides In cut zone Sr2, the 3rd cut zone Sr3 positioned at eddy flow direction of rotation Da downstreams the 3rd cut zone Sr3, two The first cut zone Sr1, the 4th cut zone Sr4 of rear side.In other words, the water jet 32C of the first water jet 32A~the 3rd does not have Be formed in the second cut zone Sr2, the 3rd cut zone Sr3 of two front sides positioned at eddy flow direction of rotation Da upstream sides Second cut zone Sr2.

Illustrate its advantage.Fig. 9 (a) is the figure for showing the toilet main body 12 that the first variation is related to.In this example, second Water jet 32B is formed at the second cut zone Sr2.

When user is to be sitting in the state urine of the toilet seat of water closet 10, sometimes by the reception of closestool portions 14 The urine that face 26 is received splashes (reference orientation Df) to surrounding.Now, when the urine of splashing is splashed to comprising edge part 28 During inner peripheral surface region including the left and right center 28a of front side, urine is transmitted in the inner peripheral surface region in the circumferential direction, may Enter from the second water jet 32B in right side water flowing path 38b.

On this point, according to present embodiment, as shown in Fig. 9 (b), when urine is splashed to the front side comprising edge part 28 During inner peripheral surface region including the 28a of left and right center, the urine transmitted in the circumferential direction in the inner peripheral surface region is difficult to from second The depth side that water jet 32B is entered in left side water flowing path 38b.Therefore, suppress urine composition and remain in the second water jet 32B's The possibility of depth side (in the water flowing portion 38 in water spray portion 36), it can correspondingly prevent the dirty, generation of stink.Therefore, it is possible to Good spatter property is obtained while good rim wash ability is obtained.

According to foregoing structure, it may have it is following the advantages of.The first variation that Figure 10 is (a) that shows Fig. 9 is related to The figure of toilet main body 12.

The centrifugal force Fc for being radially oriented outside is paid along the flushing water that the inner peripheral surface of closestool portions 14 flows.Flushing water institute The smaller then centrifugal force Fc of radius of curvature at flowing position is bigger, the more big then flowing of entrance 16 to Drainage Division 18 of the centrifugal force The water slug of current more easily dies down.

Consider to assume the situation that the second water jet 32B is arranged at the second cut zone Sr2.In this case, from water jet 32 flushing waters sprayed flow via positioned at the left and right center Pa of the front side of edge part 28 inner peripheral surface region.Toilet seat Portion 14 is formed as the ellipse that anteroposterior dimension is more than side-to-side dimensions, therefore leads to positioned at left and right center Pa inner peripheral surface region Often it is easily less than the radius of curvature of other positions.Therefore, when the second water jet is arranged at into the second cut zone Sr2, from The water slug for the flushing water that two water jet 32B spray is easy to weaken under centrifugal force Fc effects.

On this point, according to present embodiment, because the second water jet 32B is arranged at the 3rd cut zone Sr3, therefore make The flushing water sprayed from the second water jet 32B is not via in the left and right center Pa of the small edge part 28 of radius of curvature Side face region and the entrance 16 towards Drainage Division 18 flows.Therefore, formed by the flushing water sprayed from the second water jet 32B Main flow Fw water slug is not easy to weaken because of centrifugal force Fc, with the second water jet 32B is configured at into the second cut zone Sr2's Situation is compared, and can obtain good toilet seat rinse capability, dirt discharge ability.

Illustrate other features of water closet 10.

Reference picture 3.The left side water flowing path 38c of flushing water is supplied with the vertical of left part 28L to the second water jet 32B The mode that deep side extends along the longitudinal direction is formed.Left part 28Ls of the left side water flowing path 38c in edge part 28, right side The left part 28L of side where 3rd cut zone Sr3 in point 28R, formed with the second water jet 32B depth side Formed.Left side water flowing path 38c under vertical view by left part 28L depth side across front-rear center line Lb in a manner of shape Into.From another viewpoint, left side water flowing path 38c not with the right part 28R of edge part 28 depth side across preceding CB Lb mode is formed.Illustrate its advantage.

, can be with the layout of the left and right center Pb depths side of the front side not via edge part 28 according to foregoing structure Configuration left side water flowing path 38c.Therefore, with configured in a manner of the depth side of the left and right center Pb via edge part 28 it is logical The situation of water route is compared, and can be shortened water flowing path of the flushing water from being flowed into position Pa, can be made the strong flushing of water slug Water sprays from the second water jet 32B.As a result, can obtain more good rim wash ability, toilet seat rinse capability, Dirt discharges ability.Second water jet 32B position is closer to the 3rd cut zone Sr3 of closestool portions 14 rear side, more energy It is enough effectively to obtain the effect.

In addition, it is assumed that configuring water flowing road in a manner of the left and right center Pb depths side via the front side of edge part 28 In the case of footpath, it is necessary to by the first water jet 32A water flowing path and the second water jet 32B water flowing path in edge part 28 right part 28R depth side is arranged in left-right direction.On this point, according to foregoing structure, without making One water jet 32A right side water flowing path 38b and the second water jet 32B left side water flowing path 38c are in edge part 28 Right part 28R depth side is arranged in left-right direction.Therefore, it is possible to reduce the vertical of the right part 28R of edge part 28 The width dimensions of deep side part.So as to, as shown in Figure 1 and Figure 2, can reduce it is in the upper surface part 12a of toilet main body 12, from The width dimensions for the lateral portions 12b that the upper edge of closestool portions 14 extends to side.

In second edge water guide path 34B inner peripheral surface, dividing relative to the second water jet 32B to eddy flow direction of rotation Da The position opened is formed with the line interval 34Bb linearly extended.In second edge water guide path 34B inner peripheral surface, from In two water jet 32B to line interval 34Bb successive range formed with away from the second water jet 32B and curvature diminishes The curvature that is formed of mode reduce section 34Bc.In addition, in the 3rd edge water guide path 34C inner peripheral surface, relative to the 3rd The line interval 34Cb that water jet 32C is also formed with linearly extending to the separated positions of eddy flow direction of rotation Da.The 3rd Edge water guide path 34C inner peripheral surface, in the successive range from the 3rd water jet 32C to line interval 34Cb formed with Away from the 3rd water jet 32C and curvature that mode that curvature diminishes is formed reduces section 34Cc.

In this way, each edge water guide path 34B, 34C inner peripheral surface formed with from each continuous curvature of water jet 32B, 32C Reduce section 34Bc, 34Cc.Therefore, since each water jet 32B, 32C spray untill by line interval 34Bb, 34Ca In the range of, just sprayed from each water jet 32B, 32C and the strong flushing water of water slug flows in the big section of radius of curvature, therefore It is difficult to be paid big centrifugal force in the flushing water of scope flowing.Therefore, towards row after each water jet 32B, 32C ejection The current of the entrance 16 in water portion 18 are not easy to weaken from from the state just sprayed from each water jet 32B, 32C and water slug is strong.Its As a result, washing away dirt by the current of strong water slug corresponding to its, more good dirt discharging performance can be obtained.

Figure 11 (a) is the figure for showing the construction around the second water jet 32B that embodiment is related to.

The inner side standing wall portion 34b (hereinafter also referred to " inner sides that second water jet 32B passes through the radially adjoining of closestool portions 14 Standing wall portion 34b (1) ") and outside standing wall portion 34b (hereinafter also referred to " outside standing wall portion 34b (2) ") be partially formed.Two walls In portion 34b, outside standing wall portion 34b (2) circumferential direction end 34ba and inner side standing wall portion 34b (1) circumferential direction end 34bb Configured in a manner of being arranged on the dummy line Lc extended from the central point Cp of closestool portions 14.Here " arrangement " is included from horse Two standing wall portion 34b are in a manner of angular range overlapping in the circumferential direction is less than 3 ° during the central point Cp observations in bucket seat portion 14 The situation of arrangement.It is it may also be said that overlapping in the circumferential direction when two standing wall portion 34b are with from the central point Cp of closestool portions 14 Angular range be that less than 3 ° of mode configures.Illustrate its advantage.

Figure 11 (b) is the figure for showing the construction around the second water jet 32B that the second variation is related to.Consider to assume such as Such two standing wall portion 34b circumferential direction end 34ba, 34bb shown in Figure 11 (b) is not arranged on dummy line Lc and two are stood Overlapping angular range becomes big situation in wall portion 34b circumferential direction.In this case, the upstream with fold back portion 38ca respectively Hold each water route part 40 being connected with downstream diametrically arrangement form.Here, due to relative to fold back portion 38ca For radially inner side form edge water guide path 34A etc. relation, two diametrically opposite internal faces in fold back portion 38ca 38f is easy to be formed in a manner of narrowed width by with the terminal location 38g towards fold back portion 38ca.Therefore, each water route portion 40 width dimensions are divided to be also easy to be formed in a manner of with close to fold back portion 38ca narrowing.Therefore, from left side water flowing Via fold back portion 38ca until among the second water jet 32B path Rb, path is cut path 38c front and rear extension 38cb The radially opposite sides that the area position smaller than the second water jet 32B is easy to edge-on wall portion 34b inside are formed (with reference to scope Sc).It is tied Fruit is, it is difficult to carries out following design, i.e. in the water flowing path being connected with the second water jet 32B the minimum portion of passage sections product Position is that foregoing flow set portion turns into the second water jet 32B.

On the other hand, if as it was previously stated, two standing wall portion 34b circumferential direction end 34ba, 34bb is with dummy line Lc The mode of upper arrangement is formed, then each water route part 40 being connected respectively with fold back portion 38ca upstream end and downstream is difficult to Diametrically arrangement form.So as to which among foregoing path Rb, position of the passage sections product less than the second water jet 32B is difficult To be formed, it is easy to carry out designs of the second water jet 32B as flow set portion.

In addition, the cut zone Sr3 of front sides of the second water jet 32B due to being formed at closestool portions 14, therefore generally make Used time, positioned at the position for being not easy visually to be arrived by user.Therefore, even in the second water jet 32B of formation two walls The mode of portion 34b circumferential direction end 34ba, 34bb arrangement configures and even can see depth from the second water jet 32B sometimes In the case of the construction of side, by making the second water jet 32B be difficult to visually arrive in itself, it can prevent aesthetic property from declining.In addition, this In " usually using when " refer to the situation close to the recoil of water closet 10 defecation on toilet seat from front.

Figure 12 is the figure for showing the construction around the 3rd water jet 32C.

Under vertical view, by the left side water flowing path 38c of left side water flowing path 38c and front-rear center line Lb overlapping opening position Width dimensions be set to W1.Formed with from preceding CB Lb towards rear and broad-ruler in the 38c of left side water flowing path The very little change width region 38h become larger.In the 38h of the change width region, when by as the two of width dimensions W1 times Width dimensions W2 position 38i when being set to reference position 38i, after the 3rd water jet 32C is formed at compared to reference position 38i Side.Assuming that in the case where the 3rd water jet 32C is formed at reference position 38i anterior position (such as scope Sd), due to needing The wall part for flushing water to be imported to the 3rd water jet 32C is ensured around it, therefore is sprayed water around it towards second Mouth 32B water flowing path easily narrows.On the other hand, if the 3rd water jet 32C is formed at reference position 38i rear, Towards the second water jet 32B water flowing path be not easy due to for by flushing water import the 3rd water jet 32C wall part and Narrow, be easy to supply the flushing water of sufficient amount to the second water jet 32B.

As described above, the shape of closestool portions 310 is formed as follows：The flushing water sprayed from three water jets 322 distinguishes shape Into this first main flow 362,372,382.This first main flow 362,372,382 refers to, falls to three walls 220,222,224 Under, along the current of the wall 220,222,224 flowing.In addition, as it was previously stated, the shape of closestool portions 310 is formed as follows：It is this First main flow 362,372,382 is collaborated at the region of recess 316 (in recess 316).

In addition, the shape of closestool portions 310 is formed as follows：The flushing water sprayed from three water jets 322 forms this respectively The second main flow 364,374,384 of kind.This second main flow 364,374,384 refers to flow along the inner peripheral surface of edge part 308, and with Sprayed relative to each adjacent other water jets 322 on direction of rotation () of three water jets 322 in figure counterclockwise The flushing water gone out is overlapping.

On the basis of being constructed as described above, as the shape of closestool portions 310, by edge part 308, face 330, recess are received 316th, the shape of each water jet 322 is formed.As the shape of edge part 308, reception face 330 and recess 316, such as can example Lift above-mentioned curvature, gradient etc..Being formed these shapes in a manner of meeting these conditions, the main water that adjusts is in closestool portions The type of flow in 310.In addition, the shape as each water jet 322, such as above-mentioned position, size, direction can be enumerated Deng.Being formed these shapes in a manner of meeting aforementioned condition, main emission direction, the spray volume for adjusting flushing water.

Then, the action of water closet 300 is illustrated.

Water closet 300 is by the operations of the functional units such as predetermined switch, bar, and the flushing water of scheduled volume is from flow pipe 304 are supplied to water guide path 324 by inflow path 238a and water guide path 238b.The flushing water of supply is from water jet 322 Sprayed towards water flowing path 320, the dirt in closestool portions 310 is poured into the bottom of recess 316 using the water-head of flushing water Water seal portion 316e, and widely rinse in closestool portions 310.

Then, the feature of the water closet 300 of present embodiment is illustrated.

First main flow 362,372,374 of each flushing water sprayed from water jet 322 is with along the wall 226 of recess 316 The mode of wall flow, so as to strongly wash out the dirt for being attached to the wall.In addition, first main flow is towards each angle Portion 228 (also referring to Figure 20) is flowed, with the collision with wall in corner 228 mainly to horizontal direction of rotation, lower direction and upper direction point Dissipate.Because corner 228 is acute angle, therefore the current of horizontal direction of rotation are suppressed, and in gravity and from closestool top court In the presence of the first main flow flowing of bottom, the current in upper direction are also suppressed, and are correspondingly formed the strong current in lower direction.

Together with the current of whirlpool 388, the strong stream in these lower directions is from the three direction shapes corresponding to each corner 228 Into so as to which dirt is strongly rushed to draining road pipe portion 312 from water seal portion 316e.

In addition, also can widely be rinsed by the second main flow from edge part 308 to the scope for receiving face 330, can It is overall to rinse closestool portions 310.

For example, in the structure for the polygon that recess is more than circular or four sides, although strong horizontal stroke can be formed in recess Whirlpool is rotated, but the current in lower direction die down, and are unfavorable for dirt discharge.On the other hand, in water closet 300, recess 316 passes through Three walls corresponding with each side of triangle delimited, therefore can be strengthened the current in lower direction and be effectively discharged out dirt.Separately Outside, horizontal rotary water current can be weakened and suppresses whirlpool 388.

When three water jets concentrate on side, the uneven of current becomes big and the area for rinsing deficiency can be produced in toilet seat Domain.On the other hand, water closet 300 forms three water jets with the scope more than a quarter girth and below half girth 322 interval, therefore the inequality of current is inhibited, good rinse capability can be obtained.

When the configuration non-homogeneous relative to recess of three water jets, inequality can be produced on the flushing ability of the wall of recess. On the other hand, in water closet 300, in a manner of surrounding recess 316, first water jet 322a is set in the left side of recess 316, The front of recess 316 sets the second water jet 322b, sets the 3rd water jet 322c at the rear of recess 316, therefore can press down The flushing ability of the wall of recess 316 processed is uneven.

In the structure for only forming the main flow fallen while main flushing water rotation, it is contemplated that to when being fallen to recess Water slug reduce and the flushing ability of the wall of recess declined.On the other hand, in water closet 300, because water jet 322 sprays The first main flow 362,372,382 for falling towards wall 226 and being flowed along the wall 226 respectively, therefore inhibit water slug to decline And it can effectively rinse wall 226.

It is contemplated that when the first main flow 362,372,382 sprayed from water jet 322 is mainly receiving the interflow of face 330 When, water slug, direction during for being fallen to recess 316 have an impact.On the other hand, in water closet 300, the first main flow 362 To collaborate with the first main flow 382 in the region of recess 316, the first main flow 382 and the first main flow 372 are collaborated in the region of recess 316, First main flow 372 and the first main flow 362 are collaborated in the region of recess 316, therefore inhibit water during for being fallen to recess 316 Impact, the influence in direction.

By 362,372,382 respective interflow of the first main flow, further strong horizontal vortex and lower section can be formed To current, dirt can be strongly gone out.

In the junction section of the main flow of each flushing water sprayed from three water jets, do not flowed fully occasionally there are flushing water Move and cause to rinse hypodynamic situation.On the other hand, in water closet 300, the second main flow 364,374,384 is led to along edge respectively The side of sidewall portion 326a of water route 320 flows in the circumferential direction, and from the direction of rotation side spray mouth of a river 322 in three water jets 322 The flushing water of ejection is overlapping, therefore the current deficiency of the junction section of main flow is inhibited, and can rinse horse extensively and well Bucket seat portion 310.

When changing the global shape of closestool portions for current desired by the realization in flushing water, it is damaged sometimes His performance, turn into the restriction of current desired by realizing.On the other hand, in water closet 300, set in edge water flowing path 320 There is the deflecting portion 332 that the part for making flushing water current is bent inwardly, therefore independently of side of sidewall portion 326a flecition, pass through Deflecting portion 332 is set, the current of flushing water can be changed and be close to desired current.

In water closet 300, due to having a side of sidewall portion 326a part to compare circumferential direction in aforementioned change portion 332 The convex surface part 334 that both sides are protruded to inner side, therefore the change of frame portion 326b, the shape of closestool portions 310 can be suppressed most Small limit.

More than, the second invention is illustrated according to embodiment.For these embodiments to illustrate, those skilled in the art can Understand, various modifications and change, and these variations and change can be carried out in the Claims scope of the second invention It is also contained in the Claims scope of the second invention.Therefore, the description in this specification and accompanying drawing and non-limiting, should This is interpreted as exemplary.

On water closet 300, illustrate the example for using Washdown type as backwashing manner, but by with hydrocone type, rainbow Inhaling the backwashing manner of the other modes such as injecting type combination can also rinse in closestool portions 310.On water closet 300, explanation Use example of the tap water direct pressure type as way of supplying water, the gravity water supply formula using gravity can also be used in addition, rinsed The way of supplying water such as valve type.Toilet main body 302 is illustrated by taking wall-mounted closestool as an example, but can also be to be arranged at toilet Ground placed type closestool on ground.In addition, toilet main body 302 can also be with resin etc. for raw material in addition to ceramics.

In the embodiment of the second invention, the example that anticlockwise rotary water current is generated to water jet is said It is bright, but not limited to this.Such as it can also be formed in a manner of swapping left and right and generating clockwise current.

In the embodiment of the second invention, the example for being three to the water jet for being arranged at edge part is illustrated, But other sprinkler parts can also be secondarily set in addition to three water jets.
