Interconnecting piece 46 is connect with the side riser culverts 8b of distributary division 26.Interconnecting piece 46 has reception and flows into along guide part 32 Ejected wash water entrance 40, the entrance 40 also as flow into interconnecting piece 46 ejected wash water outflow outlet 44 and play function Energy.Also, interconnecting piece 46 is also temporary in internal flow until flowing out from outlet 44 from the ejected wash water that entrance 40 flows into as making When the reservoir that stops and function.The entrance 40 of interconnecting piece 46 is located at the lower section of guide part 32 and outside.The formation of entrance 40 The opening of the half cycle of the side riser culverts 8b comprising distributary division 26 or so.Postponing flow path 28 is that entrance 40, outlet 44 is common, and Make ejected wash water on one side in the delay flow path for postponing the accumulation type that while flowing in flow path 28 temporals persistence.Also, 46 shape of interconnecting piece At the bending flow path for thering is the side region side E of the water (flow) direction for making the ejected wash water flowed into from distributary division 26 court to lateral side to change. Since interconnecting piece 46 forms bending flow path, make to slow down in the flow velocity of the ejected wash water of internal flow.By including making ejected wash water Portion's flowing, the opportunity that interconnecting piece 46 can be such that the ejected wash water flows in draining bellmouth 16 more postpone than at the beginning.In this way Structure, when delay flow path 28 makes the ejected wash water flowed by the guide part 32 of distributary division 26 than flowing into more posteriorly with reach point The water flow delays of the ejected wash water in stream portion 26 and converge.

Extension flow path 48 is arranged among the side of middle section D in the wherein side region E of side and the other side.? Extension flow path 48 can be provided only among the side of middle section D in the wherein side region E of side or the other side.Although In the present embodiment, extension flow path 48 is provided only in the E of side region, but can also be centrally disposed by extension flow path 48 In region D and side region E.Flow path 48 is extended in the direction of entrance 8f and outlet 8d along connection drain elbow pipeline 8 It is upwardly extended in the front and back of closet ontology 2 on direction.Flow path 48 is extended under side view from the down-comer of drain elbow pipeline 8 The position of the lower section of road 8c extends to the position Chong Die with 8 a part of drain elbow pipeline.Extension flow path 48 makes to postpone flow path 28 It is extended in the E of side region.Extension flow path 48 makes to postpone wider array of region extension of the flow path 28 into side region E, makes to postpone The base area of flow path 28 more increases.Since extension flow path 48 increases the base area for postponing flow path 28, even if In the lower situation of the flow velocity of the ejected wash water of inflow, also it is easy to flow into ejected wash water on the wider region of delay flow path 28, Thus compared with the relatively narrow situation of the base area of delay flow path 28, it can be flowed convenient for making more ejected wash waters be flowed into delay Road.Thus, it is formed in side region E by the way that flow path 28 will be postponed, to increase base area in the E of side region, Neng Gougeng Adding effectively makes to increase in the cleaning water of the delay flow path internal flow, and does not depend on the flow velocity of the ejected wash water of inflow.Extension Flow path 48 is functioned as the reservoir that can make ejected wash water temporal persistence.Since extension flow path 48 makes to flow from interconnecting piece 46 The ejected wash water entered is flowed in a manner of turning back in extension flow path 48 towards interconnecting piece 46, therefore makes the flow velocity of the ejected wash water flowed into Slow down.

Also, as shown in Figures 5 and 6, the bottom surface 50 of delay flow path 28 is formed, and shunting is projected into distributary division 26 The lower section of the guide part 32 in portion 26 and the position opposite with guide part 32.The end 50a for postponing the bottom surface 50 of flow path 28 is overlooked It is located at down more more outward than the outer rim of vertical flow path 34.The bottom surface 50 of delay flow path 28 is formed, in interconnecting piece 46 and extended flow It is slightly tilted in road 48 towards entrance 40.Thus, it is possible to which flow path will be postponed while the flow velocity for making the ejected wash water flowed into slows down Residual water in 28 is discharged towards entrance 40.

Next, A, Figure 1B and Fig. 6 (make the movement of the flush toilet of the 1st embodiment of the invention referring to Fig.1 With) be illustrated.

The draining of A, Figure 1B and Fig. 6 to closet cleaning is carried out on the flush toilet of the 1st embodiment of the invention referring to Fig.1 When state be illustrated.In addition, indicating the stream more leading than dirt C with arrow A (A0~A6) in Figure 1A, Figure 1B and Fig. 6 The water flow of the lower leading ejected wash water of speed is indicated mainly to flow in the subsequent side of dirt C to wash away with arrow B (B0~B4) The water flow of the transport stream of dirt.Here, " the leading side of dirt C " refer to it is more leading than dirt C on the flow path of the flowing of dirt C Front side." the subsequent side of dirt C " refers on the flow path of the flowing of dirt C the and then rear side of dirt C.

As shown in Figure 1A, Figure 1B and Fig. 6, user will clean the cleaning of cistern device 18 after using flush toilet 1 The discharge outlet 20a of water tank 20 is opened, and ejected wash water is discharged to the water guide road 6 of closet ontology 2 from discharge outlet 20a.Then, by this Ejected wash water in water guide road 6 spues from the inner edge guttation mouth 12 of flush toilet 1 into ponding portion 14, carries out closet ontology 2 Cleaning.Using from water guide road 6 to the fluviation of the drop of the ejected wash water in ponding portion 14, dirt C will be included in ponding portion 14 Ejected wash water be flushed to riser culverts 8b and decline pipeline 8c from the entrance pipe 8a of drain elbow pipeline 8, and to drain elbow pipe The outlet 8d on road 8 is transported.

Firstly, comparison dirt is illustrated the case where water flow is leading and flow velocity lower cleaning water flowing.

As shown in Figure 1A, when closet cleans beginning, as shown in arrow A0, the lower leading cleaning of and flow velocity more leading than dirt C Water A is flowed in the leading side of dirt C.It is also smaller in the cleaning water for the leading ejected wash water A that the leading side of dirt C is flowed.

As shown in Figure 1A, when closet cleans beginning, leading ejected wash water A drops the side pipeline 8c from riser culverts 8b gradually downward Outflow.The flow of water of the lower leading ejected wash water A of flow velocity is weaker, as indicated by arrow a 1, along the riser culverts 8b of decline pipeline 8c The side 8e of side is flowed down.Also, leading ejected wash water A is swimmingly flowed down from side 8e along the guide surface 34b of distributary division 26, such as arrow Shown in head A2, it is guided from guide surface 34b along guide part 32 towards delay flow path 28.Leading ejected wash water A is due to Coanda effect Guide part 32 is zoomed in, and then the direction that guide part 32 is extended is biased in the direction of water flow.In this way, as shown with arrow a 3, first At least part of row ejected wash water A is flowed into the entrance 40 of the interconnecting piece 46 of delay flow path 28.As shown in the arrow A4 of Fig. 9, stream The leading ejected wash water A entered into interconnecting piece 46 is flowed from interconnecting piece 46 towards extension flow path 48.Due in interconnecting piece 46, in advance The direction of the water flow of ejected wash water A is deflected, therefore flow rate speed when velocity ratio inflow more reduces.By in interconnecting piece 46 and Flowing in flow path 48 is extended, leading ejected wash water A is sent out relative to the water flow in primary flow path being the ejected wash water flowed in vertical flow path 34 Raw delay.Leading ejected wash water A is slowly flowed in a manner of the temporal persistence in interconnecting piece 46 and extension flow path 48, and returns to master Stream.From cleaning after a period of time, when being flowed into the ejected wash water of entrance 40 of interconnecting piece 46 and tailing off or disappear, then Leading ejected wash water A in interconnecting piece 46 and extension flow path 48 is flowed as shown in the arrow A5 of Figure 1B towards outlet 44, from outlet 44 It is flowed out towards flow path 34 is indulged.

In addition, " Coanda effect " said here refers to the phenomenon that jet flow is bent along solid wall, by finger close to running water pipe Tap when, water flow to one side of finger be bent the phenomenon that be also to be generated because of Coanda effect.

Next, being illustrated to the transport stream for washing away dirt.

As shown in arrow B0, the transport stream B to be played a role in a manner of washing away dirt C is around dirt C and mainly in dirt C Subsequent side flowing.It transports stream B and forms the backwater mainly flowed in the subsequent side of dirt C.Such flow velocity for transporting stream B is higher And cleaning water is also larger.Stream B is transported to play a role in a manner of mainly washing away dirt C from subsequent side.Invention of the invention Person observes, by increasing the water of transport stream B, capable of making the power for washing away dirt C for transporting stream B and transporting the dynamic of stream B It can more improve.

As shown in Figure 1B, due to dirt C and transport stream B flow velocity with higher, as shown in arrow B1, dirt C and The mainstream for transporting stream B is flowed down along the side wall side among decline pipeline 8c with riser culverts 8b opposite side.It is dirty as shown in arrow B2 Notch 36 of the mainstream of object C and transport stream B among the sidewall 34 a of vertical flow path 34 with the side wall side of riser culverts 8b opposite side In pass through.Also, dirt C and the mainstream for transporting stream B flow down in the i.e. vertical flow path 34 of primary flow path as shown in arrow B3, to inhibit It is mutually hit with the bottom surface of delay flow path 28 and is flowed into delay flow path 28.

The ejected wash water of more ratio among its flow for flowing through the leading ejected wash water A come of the lower leading ejected wash water A of flow velocity Delay flow path 28 is directed into along guide part 32.In contrast, as shown in arrow B1 ', the higher transport stream B of flow velocity it flows through The ejected wash water of less ratio is directed into delay flow path 28 along guide part 32 among the flow of the transport stream B come.Thus, in advance Be directed among ejected wash water A along guide part 32 the leading ejected wash water A of delay flow path 28 ratio become than transport stream B it In be directed into along guide part 32 delay flow path 28 transport stream B ratio it is bigger.In addition, transporting among stream B along leading The ratio that the ratio of the transport stream B of delay flow path 28 is 0% or more is directed into portion 32.

As indicated by arrow, the leading ejected wash water A that vertical flow path 34 is flowed out to from outlet 44 converges with stream B is transported.To from out Until mouth 44 is flowed out towards vertical flow path 34, the leading ejected wash water A being flowed into delay flow path 28 as described above, which have passed through, to postpone The stipulated time flowed in flow path 28.Thus, when leading ejected wash water A postpones flow path 28 to flow into than leading ejected wash water A more posteriorly Opportunity after the stipulated time and reach the transport stream B of vertical flow path 34 of distributary division 26 and converge.Thus, flow into delay flow path A part of 28 leading ejected wash water A is converted into transport stream B.

Few leading ejected wash water A will be contributed to be appended to transport stream B the transport of dirt C as a result, as shown in arrow B4, so as to Enough increase the water of the transport stream B of dirt C, and then the transport performance for transporting dirt C can be made to improve.Arrow B4 indicates leading Ejected wash water A converges with stream B is transported, so that B is flowed in increased transport simultaneously for the flow of ejected wash water and volume.

Dirt C and transport stream B flow in downstream side discharge pipe line portion 30 towards downstream side, are discharged to building piping In 22.

Next, being illustrated referring to 1st variation of Fig. 7~Fig. 9 to the delay flow path 28 of draining bellmouth 16.

For the variation, identical symbol is marked to part identical with the 1st above-mentioned embodiment and explanation is omitted.? In the 1st above-mentioned embodiment, the delay flow path 28 of draining bellmouth 16 is to keep entrance 40 common with outlet 44 and keep ejected wash water temporary When rest on delay flow path 28 in accumulation type delay flow path.

However, as variation, can also be respectively configured and be formed using by entrance 40 and outlet 44 in the 1st embodiment The delay flow path 128 of the tortuous flow passage type of the tortuous flow passage of ejected wash water, to replace above-mentioned delay flow path 28.

Draining bellmouth 16 substantially successively has upstream side drain pipe road portion 24 from upstream side to downstream side, distributary division 26, prolongs Slow flow path 128 and downstream side discharge pipe line portion 130.

Downstream side discharge pipe line portion 130 is arranged on the downstream side of distributary division 26.Downstream side discharge pipe line portion 130 is formed in The lateral flow path of the position of building piping 22 is linearly extended in transverse direction.The downstream side in downstream side discharge pipe line portion 130 End is connect with the building piping 22 in the configuration of the lower section of the ground F configured with closet ontology 2.Downstream side discharge pipe line portion 130 are formed with the opening received from the ejected wash water under the stream of outlet 144 on the top of side section downstream.

As shown in Figure 7 to 9, delay flow path 128 forms the flow path from 26 branch of distributary division.Postpone flow path 128 in side Flow path is formed in the E of region.Delay flow path 128 is configured to, and makes ejected wash water that is more leading than dirt and flowing into from distributary division 26 than flowing into When more posteriorly converge with the water flow of ejected wash water for reaching distributary division 26.Delay flow path 128 is configured in the cross of 32 front side of guide part Upwards.The central axis in the front-back direction for postponing flow path 128 relative to closet ontology 2 forms bilateral symmetry.

Extension flow path 148 has the 1st extension of the side region E of wherein side among the side for being set to middle section D Flow path 148a, be set to the other side side region E the 2nd extension flow path 148b.In this way, extension flow path 148 is arranged on It entreats among the side of region D wherein in the side region E of side and the other side.In extension flow path 148 can also being provided only on It entreats among the side of region D wherein in the side region E of side or the other side.Although flow path in the present embodiment, will be extended 148 are provided only in the E of side region, but can also will extend in the centrally disposed region D of flow path 48 and side region E.Extension Flow path 148 is upwardly extended in the front and back of closet ontology 2 on the direction along drain elbow pipeline 8.Extension flow path 148 exists It extends under side view from the position of the lower section of the decline pipeline 8c of drain elbow pipeline 8 Chong Die with a part of drain elbow pipeline 8 Position.Extension flow path 148 extends delay flow path 28 in the E of side region.Extension flow path 148 makes to postpone flow path 28 in side It is extended in wider array of region in the E of region, increases the base area for postponing flow path 128 more.Since extension flow path 148 makes to prolong The base area of slow flow path 128 increases, therefore even if is also easy to make to clean in the lower situation of flow velocity of the ejected wash water of inflow Water flows on the wider region of delay flow path 128, thus compared with the relatively narrow situation of the base area of delay flow path 128, Can be convenient for that more ejected wash waters is made to be flowed into delay flow path.Thus, it is formed in side region E by the way that flow path 128 will be postponed, with Just increase base area in the E of side region, can more effectively make to increase in the cleaning water of the delay flow path internal flow Add, and does not depend on the flow velocity of the ejected wash water of inflow.Extend flow path 148 also as the reservoir that can make ejected wash water temporal persistence and It functions.Extension flow path 148 is configured to, in the ejected wash water flowed into from interconnecting piece 146 relative to vertical in extension flow path 48 Direction and into lateral flow, make flow into ejected wash water flow velocity slow down.

The bottom surface 50 of delay flow path 28 is formed, and slightly inclines in interconnecting piece 46 and extension flow path 48 towards outlet 144 Tiltedly.Thus, it is possible to which residual water is discharged towards outlet 144 while making the flow velocity of the ejected wash water flowed into suitably slow down.

Outlet 144 is formed in different positions as the outlet portion separated with entrance 40.Outlet 144 is formed on Extend the downstream of flow path 148.Outlet 144 has the 1st outlet 144a of the outlet to form the 1st extension flow path 148a, forms the 2nd Extend the 2nd outlet 144b of the outlet of flow path 148b.Outlet 144 is formed on the top in downstream side discharge pipe line portion 130 and builds Build the top of object piping 22.Outlet 144 is in lower section direction upper opening, to make ejected wash water run down into the downstream side drainpipe of lower section In road portion 130 and building piping 22.Thus, delay flow path 128 is to be respectively formed with entrance 40 and outlet 144 and form cleaning The delay flow path of the tortuous flow passage type of the tortuous flow passage of water.Through this structure, delay flow path 128 makes along distributary division 26 The ejected wash water of the inflow of guide part 32 from downstream side discharge pipe line portion 130 than flow into when more posteriorly with reach distributary division 26 cleaning The water flow of water is converged.In addition, exporting the 1st extension flow path 148a of 144a from interconnecting piece 46 to the 1st, going out from interconnecting piece 46 to the 2nd The 2nd extension flow path 148b of mouth 144b is independently formed.

Next, A, Figure 1B, Fig. 7~Fig. 9 couples and the flush toilet of the 1st embodiment of the invention prolong referring to Fig.1 The relevant movement (effect) of the 1st variation of slow flow path is illustrated.

A, Figure 1B, Fig. 8 and Fig. 9 are enterprising to the flush toilet of the 1st variation in the 1st embodiment of the invention referring to Fig.1 The state when draining of row closet cleaning is illustrated.In addition, in Figure 1A, Figure 1B, Fig. 8 and Fig. 9, with arrow A (A0~A4, A7 and A8) indicate the water flow of the lower leading ejected wash water of the flow velocity more leading than dirt C, with arrow B (B0~B3, B5 and B6) come Indicate the water flow that the transport stream of dirt is washed away comprising dirt C and mainly in the flowing of the subsequent side of dirt C.For the variation Movement, identical symbol is marked to part identical with the 1st above-mentioned embodiment and explanation is omitted.

As shown in Figure 1A, when closet cleans beginning, as shown in arrow A0, the lower leading cleaning of and flow velocity more leading than dirt C Water A is flowed in the leading side of dirt.

As shown in Figure 1A, when closet cleans beginning, leading ejected wash water A drops the side pipeline 8c from riser culverts 8b gradually downward Outflow.The flow of water of the lower leading ejected wash water A of flow velocity is weaker, as indicated by arrow a 1, along the riser culverts 8b of decline pipeline 8c The side 8e of side is flowed down.Also, leading ejected wash water A is swimmingly flowed down from side 8e along the guide surface 34b of distributary division 26, such as arrow Shown in head A2, it is guided from guide surface 34b along guide part 32 towards delay flow path 128.Leading ejected wash water A is due to Coanda effect Guide part 32 is zoomed in, and then the direction that guide part 32 is extended is biased in the direction of water flow.As shown in figure 9, leading ejected wash water A At least part be flowed into as shown with arrow a 3 delay flow path 128 entrance 40.As represented by arrow a 4, it is flowed into interconnecting piece Leading ejected wash water A in 146 is flowed from interconnecting piece 146 towards extension flow path 148.Due in interconnecting piece 46, leading ejected wash water A Water flow direction it is deflected, therefore flow velocity when velocity ratio flows into more reduces.

Since interconnecting piece 146 and extension flow path 148 form tortuous flow passage, leading ejected wash water A is in extension flow path 148 Flowing, and flowed as indicated by arrow a 7 towards the outlet 144 of extension flow path 148.By in interconnecting piece 146 and extension flow path 148 Interior flowing, leading ejected wash water A postpone relative to the water flow in primary flow path being the ejected wash water flowed in vertical flow path 34.In advance Ejected wash water A as shown in arrow A8, on the direction of lower section under the stream of outlet 144, runs down into downstream side discharge pipe line portion in fig. 8 130 and building piping 22 in.

Next, being illustrated to the transport stream for washing away dirt.

In Figure 1A and Figure 1B, as shown in arrow B0, the transport to be played a role in a manner of washing away dirt C flows B in the week of dirt C It encloses and is mainly flowed in the subsequent side of dirt C.As shown in arrow B1, the mainstream of dirt C and transport stream B are along decline pipeline 8c's It is flowed down with the side wall side of riser culverts 8b opposite side.The mainstream of dirt C and transport stream B are as shown in arrow B2 in the side of vertical flow path 34 Pass through in the notch 36 of wall 34a.Also, dirt C and the mainstream for transporting stream B flow down in vertical flow path 34 as shown in arrow B3, Delay flow path 128 is flowed into inhibit to hit with 50 phase of bottom surface of delay flow path 128.

As shown in figure 8, the mainstream of dirt C and transport stream B flow in downstream side discharge pipe line portion 130 as shown in arrow B5 It is dynamic.On the downstream side part in downstream side discharge pipe line portion 130, the leading ejected wash water A flowed down from outlet 144 is as shown in arrow A8 Converge with dirt C and the mainstream for transporting stream B.Until being flowed out from outlet 144 towards downstream side discharge pipe line portion 130, as described above The leading ejected wash water A in delay flow path 128 is flowed into interconnecting piece 146 and the tortuous flow passage for the predetermined distance for extending flow path 148 In pass through, and pass through the stipulated time.Also, the flow velocity of the leading ejected wash water A passed through in tortuous flow passage is lower, flows through from back The flow velocity of the transport stream B come is then higher.Thus, the leading ejected wash water A of delay flow path 128 is flowed into flow into than leading ejected wash water A When opportunity being delayed by after the stipulated time more posteriorly, in the position of the downstream side part in downstream side discharge pipe line portion 130 It sets, converges with the transport stream B for the vertical flow path 34 for reaching distributary division 26.Thus, flow into the leading ejected wash water A of delay flow path 128 A part be converted into transport stream B.Few leading ejected wash water A will be contributed to be appended to transport stream B the transport of dirt C as a result, As shown in arrow B6, so as to increase the water of transport stream B of dirt C, and then the transport performance for transporting dirt C can be made It improves.Arrow B6 indicates that leading ejected wash water A converges with stream B is transported, thus the flow of ejected wash water and volume increased transport simultaneously Flow B.

Dirt C and transport stream B flow in downstream side discharge pipe line portion 30 further towards downstream side, are discharged to building In object piping 22.

Next, the 2nd variation of the delay flow path 28 of 0 pair of draining bellmouth 16 is illustrated referring to Fig.1.For the deformation Example marks identical symbol to part identical with the 1st above-mentioned embodiment and explanation is omitted.Implement the above-mentioned the 1st In mode, the delay flow path 28 of draining bellmouth 16 is to keep entrance 40 common with outlet 44 and flow ejected wash water temporal persistence in delay The delay flow path of accumulation type in road 28.

However, as variation, can also be respectively configured and be formed using by entrance 40 and outlet 44 in the 1st embodiment The delay flow path 228 of the tortuous flow passage type of the tortuous flow passage of ejected wash water, to replace above-mentioned delay flow path 28.

Draining bellmouth 16 substantially successively has upstream side drain pipe road portion 24 from upstream side to downstream side, distributary division 26, prolongs Slow flow path 228 and downstream side discharge pipe line portion 30.

Figure 10 is as indicated, delay flow path 228 forms the flow path from 26 branch of distributary division.Postpone flow path 228 in side region E Middle formation flow path.Delay flow path 228 is configured to, and makes more to lean on when more leading than dirt and ejected wash water ratio inflow from the inflow of distributary division 26 The water flow with the ejected wash water for reaching distributary division 26 is converged afterwards.Delay flow path 228 is configured in the transverse direction of 32 front side of guide part.Prolong Slow flow path 228 forms bilateral symmetry relative to the central axis in the front-back direction of closet ontology 2.

Delay flow path 228 has the interconnecting piece 246 connecting with distributary division 26, extends from interconnecting piece 246 to the side region side E Extension flow path 248.

Interconnecting piece 246 is connect with the side riser culverts 8b of distributary division 26.Interconnecting piece 246 has reception and flows along guide part 32 The entrance 40 of the ejected wash water entered.Also, interconnecting piece 246 also as make from entrance 40 flow into ejected wash water to from outlet 244 flow out Until in internal flow and the reservoir of temporal persistence and function.Delay flow path 228 be also equipped with separated with interconnecting piece 246 and Flow into the outlet 244 of the ejected wash water outflow in delay flow path 228.Outlet 244 forms the outlet of extension flow path 248.Thus, The interconnecting piece 246 and extension flow path 248 that postpone flow path 228 form the tortuous flow passage from entrance 40 to outlet 244.

Interconnecting piece 246, which is formed, makes the water (flow) direction of the ejected wash water flowed into from distributary division 26 towards side region E to lateral side The bending flow path that side changes.Since interconnecting piece 246 forms bending flow path, subtract the flow velocity of the ejected wash water in internal flow Speed.By flowing ejected wash water in interconnecting piece 246, interconnecting piece 246 can be such that the ejected wash water flows through in draining bellmouth 16 Opportunity ratio more postpones at the beginning.

Extension flow path 248 has the 1st extension of the side region E of wherein side among the side for being set to middle section D Flow path 248a, be set to the other side side region E the 2nd extension flow path 248b.In this way, extension flow path 248 is provided only on Among the side of middle section D wherein in the side region E of side and the other side.Extension flow path 248 can also be provided only on Among the side of middle section D wherein in the side region E of side or the other side.Although in the present embodiment, by extended flow Road 248 is provided only in the E of side region, but extension flow path 248 can also be arranged in middle section D and side region E.Extension Flow path 248 is upwardly extended in the front and back of closet ontology 2 on the direction along drain elbow pipeline 8.Extension flow path 248 exists Extend to the U-shaped revolution in outside towards rear after temporarily extending from interconnecting piece 246 towards the front of closet ontology 2, and extends to The side of distributary division 26.Flow path 248 is extended to extend under side view from the position of the lower section of the decline pipeline 8c of drain elbow pipeline 8 To the position Chong Die with 8 a part of drain elbow pipeline.Extension flow path 248 extends delay flow path 228 in the E of side region. Extension flow path 248 extends delay flow path 228 in the wider array of region in the E of side region, makes the bottom surface face for postponing flow path 228 Product more increases.Since extension flow path 248 increases the base area for postponing flow path 228, even if in the ejected wash water of inflow The lower situation of flow velocity under, be also easy to make ejected wash water to flow on the wider region of delay flow path 228, thus flow with delay The situation that the base area on road 228 is relatively narrow is compared, and can be convenient for that more ejected wash waters is made to be flowed into delay flow path.Thus, pass through Delay flow path 228 is formed in the E of side region, to increase base area in the E of side region, can more effectively be made Increase in the cleaning water of the delay flow path internal flow, and does not depend on the flow velocity of the ejected wash water of inflow.Extension flow path 248 is also made It is functioned for the reservoir of ejected wash water temporal persistence can be made.Extension flow path 248 is configured to, and flows into from interconnecting piece 246 Ejected wash water in extension flow path 248 and over a longer distance into lateral flow, so that the flow velocity of the ejected wash water flowed into is slowed down.

A, Figure 1B, Figure 12~Figure 14 are to the progress closet cleaning on the flush toilet of the 2nd embodiment of the invention referring to Fig.1 Draining when state be illustrated.In addition, in Figure 1A, Figure 1B, Figure 12 and Figure 13, with arrow A (A0, A1, A11~A17) It indicates the water flow of the lower leading ejected wash water of the flow velocity more leading than dirt C, with arrow B (B0, B1, B7~B11) indicates main It to be flowed in the subsequent side of dirt C to wash away the water flow of the transport stream of dirt.Due to the flush toilet of the 2nd embodiment 401 closet ontology 2 is roughly the same with the closet ontology 2 of flush toilet 1 of the 1st embodiment, thus referring especially to Figure 1A, The water flow of ejected wash water in the closet ontology 2 of Figure 1B impacts flush w.c.pan 401 is illustrated, and to above-mentioned of the invention The identical part in part of the flush toilet 1 of 1 embodiment then marks identical symbol and their explanation is omitted.

As shown in Figure 1A, when such closet cleans beginning, as shown in arrow A0, and flow velocity lower elder generation more leading than dirt C Row ejected wash water A is flowed in the leading side of dirt C.The flow of water of the lower leading ejected wash water A of flow velocity is weaker, as indicated by arrow a 1, edge The side 8e of the side riser culverts 8b of decline pipeline 8c flow down.

In Figure 12 as shown in arrow A11, the leading ejected wash water A flowed down in upstream side drain pipe road portion 424 is under Fang Liudong, and it is flowed into distributary division 426.In Figure 13 as shown in arrow A12, the leading ejected wash water A for being flowed into distributary division 426 exists To lateral flow in lateral flow path 434.Since the flow velocity of leading ejected wash water A is lower, become easy in lateral flow path 434 Right and left diffuse up.Leading ejected wash water A is flowed from the side wall 434a of lateral flow path 434 along guide surface 434b, such as arrow Shown in A13, it is guided from guide surface 434b along guide part 432 towards delay flow path 428.Leading ejected wash water A is because of Coanda effect And guide part 432 is zoomed in, the direction that guide part 432 is extended is biased in the direction of water flow.In this way, leading ejected wash water A is extremely Few a part is flowed into as shown in arrow A14 from the entrance 440 of delay flow path 428.The leading ejected wash water being flowed into interconnecting piece 446 A is flowed as shown in arrow A15 from interconnecting piece 446 towards extension flow path 448.Due to leading ejected wash water A in interconnecting piece 46 water flow Direction deflection, therefore velocity ratio flow into when flow velocity more reduce.By being flowed in interconnecting piece 446 and extension flow path 448, Leading ejected wash water A relative to the ejected wash water flowed in primary flow path, that is, lateral flow path 434 water flow and postpone.Cleaning in advance Water A is slowly flowed in a manner of the temporal persistence in interconnecting piece 446 and extension flow path 448, and returns to mainstream.Since cleaning It rises after a period of time, when the ejected wash water of the entrance 440 of inflow delay flow path 428 tails off or disappears, is then flowed into connection Leading ejected wash water A in portion 446 and extension flow path 448 is as shown in arrow A16, towards 444 flowing of outlet, from exporting 444 directions Lateral flow path 434 flows out.

Next, being illustrated to the transport stream for washing away dirt.

As illustrated in figures 1A and ib, when closet cleans beginning, using from water guide road 6 to the drop of the ejected wash water in ponding portion 14 Fluviation is formed with the transport stream B for strongly washing away dirt.

As shown in arrow B0, the transport stream B to be played a role in a manner of washing away dirt C is around dirt C and mainly in dirt C Subsequent side flowing.Dirt C and transport stream B mainstream as shown in arrow B1 along decline pipeline 8c among with riser culverts 8b phase The side wall side tossed about flows down.The mainstream of the dirt C as shown in arrow B1 and transport stream B to clean in advance shown in such as arrow A1 The opportunity flowing of water A later.In Figure 12 as shown in arrow B7, the dirt C and fortune that are flowed down in upstream side drain pipe road portion 424 It send the mainstream of stream B to flow downward, and is flowed into distributary division 426.In Figure 13 as shown in arrow B8, it is flowed into distributary division The mainstream of 426 dirt C and transport stream B are in lateral flow path 434 to lateral flow.Due to the main current flow of dirt C and transport stream B Speed is higher, therefore the right and left being not easy in lateral flow path 434 extends up, thus substantially one in lateral flow path 434 The mode directly advanced flows.Thus, as shown in arrow B9, dirt C and the mainstream for transporting stream B be not easy along guide part 432 and It is directed toward delay flow path 428, to advance always.In addition, in the water flow as shown in arrow B9, dirt C and transport stream B Mainstream pass through in the notch 436 of the lower part of lateral flow path 434.Also, the dirt C and mainstream such as arrow B10 for transporting stream B It is shown to be flowed down in lateral flow path 434, it is mutually hit to inhibit with the downstream side 450 of the entrance 440 of delay flow path 428 It is flowed into delay flow path 428.

The ejected wash water of more ratio among its flow for flowing through the leading ejected wash water A come of the lower leading ejected wash water A of flow velocity Delay flow path 428 is directed into along guide part 432.In contrast, flow velocity it is higher transport stream B its flow through come transport stream B Flow among less ratio ejected wash water along guide part 432 be directed into delay flow path 428.Thus, leading ejected wash water A it In be directed into along guide part 432 delay flow path 428 leading ejected wash water A ratio become than transport stream B among along Guide part 432 and be directed into delay flow path 428 transport stream B ratio it is bigger.In addition, transporting among stream B along guide part 432 and be directed into delay flow path 428 transport stream B ratio be 0% or more ratio.

As shown in arrow A17, the leading ejected wash water A for flowing out to lateral flow path 434 from outlet 444 converges with stream B is transported.Extremely Until flowing out from outlet 444 towards lateral flow path 434, the leading ejected wash water A being flowed into interconnecting piece 446 as described above be have passed through The stipulated time flowed in delay flow path 428.Thus, postpone the leading ejected wash water A of flow path 428 to flow than leading ejected wash water A Opportunity after the stipulated time more posteriorly when entering to delay flow path 428, with the lateral flow path 434 that reaches distributary division 426 Stream B is transported to converge.Thus, a part for being flowed into the leading ejected wash water A of delay flow path 428 is converted into transport stream B.

Few leading ejected wash water A will be contributed to be appended to transport stream B the transport of dirt C as a result, as shown in arrow B11, so as to Enough increase the water of the transport stream B of dirt C, and then the transport performance for transporting dirt C can be made to improve.Arrow B11 is indicated first Row ejected wash water A converges with stream B is transported, so that B is flowed in increased transport simultaneously for the flow of ejected wash water and volume.

Dirt C and the downstream side discharge pipe line portion 430 for transporting stream B towards downstream side are flowed, and building piping is discharged to In 22.

According to the flush toilet 401 of above-mentioned the 2nd embodiment of the invention, in cleaning, distributary division 426 makes than dirt At least part of the low ejected wash water of the leading flow velocity of object is flowed into delay flow path 428, and delay flow path 428 makes to postpone the clear of flow path Opportunity when wash water than the ejected wash water to flow into more posteriorly is converged with the transport stream for washing away dirt for reaching distributary division 426.At this point, Since flow path is formed in the side region E between drain elbow pipeline 8 and skirt section 9 by delay flow path 428, make to postpone flow path 428 extend to the wider region of the side region side E, so as to increase the base area for postponing flow path 428, and then can The ejected wash water for keeping the ratio dirt of more waters leading is flowed into delay flow path 428.Thus, according to the present invention, even if because water-saving Change in the case where reducing cleaning water, the ejected wash water that can also make the ratio dirt of more waters leading is from delay flow path 428 Converge with the transport stream B for washing away dirt, so as to increase the water of transport stream B of dirt, and then can make to transport dirt Transport performance improve.

In addition, it is assumed that not formed in the E of side region flow path 428 will be postponed, and it is made only in middle section D, thus can not In the case where increasing base area to lateral side, then it is contemplated that increase the inner space of the up and down direction of delay flow path 428 Mode is formed, to increase the cleaning water in the delay flow path internal flow.However, being flowed into delay flow path 428 Ejected wash water the lower situation of flow velocity under, water level can not rise, then cause not increasing in the cleaning water of internal flow.Cause And according to the present invention, it is formed in side region E by the way that flow path 428 will be postponed, to increase base area in the E of side region Add, can more effectively make to increase in the cleaning water of the delay flow path internal flow, and do not depend on the ejected wash water of inflow Flow velocity.Thus, in accordance with the invention it is possible to which the ejected wash water for keeping the ratio dirt of more waters leading is from delay flow path 428 and washes away dirt The transport stream B of object converges.

In addition, flush toilet 401 according to the present embodiment, since interconnecting piece 446 makes from the clear of the inflow of distributary division 426 The water (flow) direction of wash water changes towards the side region side E, therefore flows the ejected wash water more leading than dirt in extension flow path 448 Flow velocity reduce, so as to increase time for flowing in extension flow path 448.It is flowed thereby, it is possible to inhibit more leading than dirt Enter the case where flowing out to distributary division 426 before the transport stream of dirt reaches distributary division to the ejected wash water for postponing flow path 428.Cause And in accordance with the invention it is possible to which the ejected wash water for more effectively making the ratio dirt of more waters leading flow path 428 and is washed away from delay The transport stream B of dirt converges.

Also, flush toilet 401 according to the present embodiment, among the side by being set to middle section D wherein The extension flow path 448 of the side region E of side and the other side can make to postpone wider array of region of the flow path 428 to the side region side E Extension, so as to increase the base area for postponing flow path 428 more.Thus, in accordance with the invention it is possible to convenient for making more water The leading ejected wash water of the ratio dirt of amount is flowed into delay flow path 428.

Also, flush toilet 401 according to the present embodiment, since extension flow path 448 is along connection drain elbow The side in the direction of the entrance 8f and outlet 8d of pipeline 8 upwardly extends, therefore makes to postpone flow path 428 to the wider of the side region side E Region extension, so as to make postpone flow path 428 base area more increase.Thus, in accordance with the invention it is possible to convenient for making The leading ejected wash water of the ratio dirt of more waters is flowed into delay flow path 428.

Also, flush toilet 401 according to the present embodiment, since draining bellmouth 416 is seperated with closet ontology 2 Resin component, therefore compared with draining the case where bellmouth is, for example, ceramic, foozle can be reduced, so as to which stream will be postponed Road 428 is more effectively set to side region E.

Also, flush toilet 401 according to the present embodiment, extension flow path 448 are provided only in the E of side region. In the E of side region, for extending the configuration of flow path 448, it is not easy to be held by the shape with drain elbow pipeline 8 and with draining The entry position of the building piping 22 of mouth connection limits accordingly.Thus, in accordance with the invention it is possible to which extension flow path 448 is answered It defecates for bath corresponding with the entry position of the shape of various drain elbow pipelines 8 and building piping 22 Device.

Next, 5 to Figure 17 being illustrated referring to Fig.1 to the flush toilet 501 of the 3rd embodiment of the invention.

Outlet 544 is formed in different positions as the outlet portion separated with entrance 540.Outlet 544 is formed In the downstream of extension flow path 548.Outlet 544 has the 1st outlet 544a of the outlet to form the 1st extension flow path 548a, is formed 2nd outlet 544b of the outlet of the 2nd extension flow path 548b.Outlet 544 is to be opened on the side wall of the lateral flow path 534 of distributary division 26 The mode of 534a is formed.Also, outlet 544 is located at than 532 upstream side of guide part.Outlet 544 makes ejected wash water flow out to cross Into flow path 534.Thus, delay flow path 528 is to be respectively formed entrance 540 and outlet 544 to form the detour stream of ejected wash water The delay flow path of the tortuous flow passage type on road.Through this structure, delay flow path 528 makes the guide part 532 by distributary division 526 And the ejected wash water flowed into than flowing into when more posteriorly converge with the water flow of ejected wash water for reaching distributary division 526.In addition, from interconnecting piece The 1st extension flow path 548a of 546 to the 1st outlet 544a, the 2nd extension flow path 548b quilt that 544b is exported from interconnecting piece 546 to the 2nd It is individually formed.

In addition, in the above-described 3rd embodiment, being connected to drain elbow pipeline 8 and dirt being made to be discharged to downstream side It is the resin component seperated with closet ontology 2 that the discharge pipe line of building piping 22, which drains bellmouth 516,.However, implementing the 3rd In mode, as variation, discharge pipe line can also be configured to a component being integrally formed with closet ontology 2.Although one The closet ontology 2 and discharge pipe line that body is formed are ceramic, but may be resin system.

Next, A, Figure 1B, Figure 17 (make the movement of the flush toilet of the 3rd embodiment of the invention referring to Fig.1 With) be illustrated.

The draining of A, Figure 1B, Figure 17 to closet cleaning is carried out on the flush toilet of the 3rd embodiment of the invention referring to Fig.1 When state be illustrated.In addition, indicating to compare dirt with arrow A (A0, A1, A25~A30) in Figure 1A, Figure 1B and Figure 17 The water flow of the lower leading ejected wash water of C leading flow velocity is indicated mainly with arrow B (B0, B1, B15~B20) dirt C's It flows to wash away the water flow of the transport stream of dirt in subsequent side.Due to the closet ontology of the flush toilet 501 of the 3rd embodiment 2 is roughly the same with the closet ontology 2 of flush toilet 1 of the 1st embodiment, therefore big referring especially to Figure 1A, Figure 1B impacts flush The water flow of ejected wash water in the closet ontology 2 of closet 501 is illustrated, and to above-mentioned the 1st embodiment of the invention The identical part in the part of flush toilet 1 then marks identical symbol and their explanation is omitted.

Compare being illustrated the case where water flow is leading and flow velocity lower cleaning water flowing for dirt.

As shown in Figure 1A, when closet cleans beginning, as shown in arrow A0, the lower leading cleaning of and flow velocity more leading than dirt C Water A is flowed in the leading side of dirt C.The flow of water of the lower leading ejected wash water A of flow velocity is weaker, as indicated by arrow a 1, along decline The side 8e of the side riser culverts 8b of pipeline 8c is flowed down.

The leading ejected wash water A flowed down in upstream side drain pipe road portion 524 flows downward, and is flowed into distributary division 526.As shown in arrow A25, the leading ejected wash water A of distributary division 526 is flowed into lateral flow path 534 to lateral flow.Due to The flow velocity of leading ejected wash water A is lower, therefore the right and left become easy in lateral flow path 534 diffuses up.Leading ejected wash water A It is flowed from the side wall 534a of lateral flow path 534 along guide surface 534b, as shown in arrow A26, from guide surface 534b along guiding Portion 532 is guided towards delay flow path 528.Leading ejected wash water A is zoomed in guide part 532, the side of water flow because of Coanda effect The direction extended to deviation guide part 532.In this way, at least part of leading ejected wash water A is as shown in arrow A27 from entrance 540 are flowed into delay flow path 528.The leading ejected wash water A in interconnecting piece 546 is flowed into as shown in arrow A28, from interconnecting piece 546 Change 180 degree direction rearward and is flowed towards extension flow path 548.Due to leading ejected wash water A in interconnecting piece 546 water flow Rearward direction deflects in direction, therefore flow velocity when velocity ratio inflow more reduces.

Leading ejected wash water A in interconnecting piece 546 and extension flow path 548 due to flowing, relative in primary flow path i.e. cross The water flow of the ejected wash water flowed into flow path 534 and postpone.Since interconnecting piece 546 and extension flow path 548 form detour stream Road, therefore leading ejected wash water A flows in extension flow path 548, and towards the outlet 544 of extension flow path 548 as shown in arrow A29 Flowing.Due to the elongated amount flowed in interconnecting piece 546 and extension flow path 548 of the distance of flow path, leading ejected wash water A phase For the ejected wash water flowed in primary flow path, that is, lateral flow path 534 water flow and be delayed by.Leading ejected wash water A such as arrow A30 institute Show from outlet 544 and converges to lateral flow path 534.

Next, being illustrated to the transport stream for washing away dirt.

In Figure 1A and Figure 1B, as shown in arrow B0, the transport to be played a role in a manner of washing away dirt C flows B in the week of dirt C It encloses and is mainly flowed in the subsequent side of dirt C.Dirt C and transport stream B mainstream as shown in arrow B1 along decline pipeline 8c it In flowed down with the side wall side of riser culverts 8b opposite side.As shown in figure 17, the dirt flowed down in upstream side drain pipe road portion 524 C and the mainstream for transporting stream B flow downward as shown in arrow B15, and are flowed into distributary division 526.As shown in arrow B16, stream Enter to distributary division 526 dirt C and transport stream B mainstream in lateral flow path 534 to lateral flow.Dirt C's and transport stream B Downstream discharge pipe line portion 530 flows down mainstream due to the weight of dirt C.The water flow such as arrow of a part of dirt C and transport stream B Delay flow path 528 is directed into shown in head B17 along guide part 532.The water flow such as arrow B18 of a part of transport stream B It is shown to be flowed from interconnecting piece 546 towards extension flow path 548, and lateral flow path is flow to from outlet 544 as shown in arrow B19 534。

It is flowed in this way, flowing out to the leading ejected wash water A of lateral flow path 534 from outlet 544 and transporting a part of stream B and transport The mainstream of B is converged.Thus, leading ejected wash water A than leading ejected wash water A and transport stream B to be flowed into when postponing flow path 528 more posteriorly Opportunity after the stipulated time and reach the transport stream B of lateral flow path 534 of distributary division 526 and converge.Thus, flow into delay The leading ejected wash water A of flow path 528 and a part for transporting stream B are converted into subsequent transport stream B.

Few leading ejected wash water A will be contributed to be appended to transport stream B the transport of dirt C as a result, as shown in arrow B20, so as to Enough increase the water of the transport stream B of dirt C, and then the transport performance for transporting dirt C can be made to improve.Arrow B20 is indicated first Row ejected wash water A converges with stream B is transported, so that B is flowed in increased transport simultaneously for the flow of ejected wash water and volume.
