Fig. 4 is the figure in the line C-C section for the closestool portions 14 for representing Fig. 2.

As shown in Figure 2, Figure 4 shows, jet 28 in a manner of crossing over the initial water level WL1 of water 44 up and down to form.Jet 28 upper portion is configured at the upper places of initial water level WL1 than water 44, and turn into makes injection supply water via its inner side The state connected in road 58 with the airspace in closestool portions 14.The lower portion configuration of jet 28 is more first than water 44 Beginning, water level WL1 located more on the lower, turned into the state being submerged in its water 44.Specifically, the lower edge 28a configurations of jet 28 exist Locate more on the lower than initial water level WL1.Lower edge 28a is for jet 28 with respect to the water level in jet 28 in vertical A part for downside.

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

(1) jet 28 of water closet 10 turns into it to be formed in a manner of crossing over the initial water level WL1 of water 44 up and down Lower portion is submerged in the state in the water 44 of initial water level.Thus, after toilet flushing, will be arrived via injection water route 58 The water such as make-up water, residual water up to jet 28 do not reach the inner surface in toilet seat portion 14 and collaborated in water 44.Therefore, it is possible to Flowed down after suppressing toilet flushing from jet 28 along the striated water of the inner surface of closestool portions 14, prevent toilet flushing from causing Closestool portions 14 in degraded appearance.Should illustrate, " make-up water " here refers to, because of toilet flushing and water 44 via After Drainage Division 18 is discharged, for the water that water 44 is stockpiled into initial water level WL1 again and supplied.In addition, " residual water " refers to, After flushing water from flush water supply device 104 terminates supply, edge water flowing road 56A, 56B, injection water route are remained in Water in 58.

In addition, it is assumed that striated water flows down from jet 28 along the inner surface of closestool portions 14, then the one of striated water Divide sometimes to be attached to the state of the inner surface of closestool portions 14 residual.In the case, according to being attached to closestool portions 14 The water quality of the water of inner surface, spot is produced in attachment position after its water evaporation.On this point, according to present embodiment, by Striated water is flowed down from jet 28 to the inner surface of closestool portions 14 in suppression, the residual for suppressing striated water causes toilet seat The inner surface spot in portion 14, it can effectively prevent the degraded appearance caused by toilet flushing in closestool portions 14.In addition, pass through The residual for suppressing striated water causes the inner surface spot of closestool portions 14, additionally it is possible to will remain cleaning in closestool portions 14.

In addition, jet 28 is turned into via jet 28 by being formed in a manner of crossing over the initial water level WL1 of water 44 up and down Upper portion on the inside of make the state that injection water route 58 connects with the airspace in closestool portions 14.Illustrate that its is excellent Point.

Fig. 5 is the schematic diagram for representing the type of flow of flushing water in injection water route 58.Fig. 5 (a) represents to start to rush The state washed before closet.In detail in this figure, for purposes of illustration only, on closestool portions 14, Drainage Division 18, injection water route 58 etc. Position, size and dimension, show and other figure differences.

If making flushing water W be supplied to left hand edge water flowing road 56B, such as shown in Fig. 5 (b), flushing water flows from introducing port 64 Enter in injection water route 58, flushing water is slowly full of from injection with the side of introducing port 64 of water route 58.Flushing water W flows into injection With in water route 58, injection is rinsed water W with the air in water route 58 and presses to the side (reference orientation Pa) of jet 28.Now, As it was previously stated, airspace of the injection in water route 58 turns into inner side and the closestool portions via the upper portion of jet 28 The state of airspace connection in 14, thus injection with the air in water route 58 via being swimmingly vented inside jet 28 (reference orientation Pb).Assuming that jet 28 is overall when being submerged in water 44, injection with the air in water route 58 with as The state of bubble sprays from jet 28, therefore due to the plosive of gassing, can bring sense of discomfort to user.This Point, according to present embodiment, in toilet flushing, it can prevent the bubble from jet 28 from spraying, therefore can prevent from sending out The plosive of anger bubble, the mute of toilet stool washing action can be realized.In addition, in addition, by preventing from coming from jet 28 bubble sprays, and can prevent from bringing user's sense of discomfort in terms of outward appearance.

Then, the further feature of water closet 10 is illustrated.

As shown in Fig. 5 (a), injection with water route 58 from by left hand edge water flowing road 56B flow into flushing water importing Mouth 64 arrives the scope of jet 28, continuous airspace 66 when having non-washed.Here " airspace 66 " refers to be full of The space of air.It means that in the scope, the sky for cutting off water flowing direction is not stockpiled with a part for water route 58 in injection The water shutoff of flow of air.Illustrate its advantage.

Fig. 6 is to represent the schematic diagram in injection type of flow of flushing water in water route 58 of variation.

It is contemplated that assume to form the situation of water shutoff 68 with water route 58 in injection as shown in Fig. 6 (a).In this feelings Under condition, turn into the shape that the upstream side air 70 split by water shutoff 68 and downstream air 72 in injection water route 58 be present State.If flushing water is flowed into injection water route 58 from left hand edge water flowing road 56B in this condition, such as Fig. 6 (b) institute Show, upstream side air 70 is rinsed water W together with water shutoff 68 and released to direction Pc.Thus, closestool portions 14 are arrived at the interflow of water shutoff 68 Bottom in water 44, so as to as shown in Fig. 6 (c), may be remained in air in injection water route 58 State, water 44 rise to (reference orientation Pd) untill jet 28 floods from initial water level WL1.In the case, its remaining Air (reference orientation Pe) is vented from jet 28 with the state as bubble, consequently, it is possible to produce bubbles burst sound.

On the other hand, according to foregoing composition, the water shutoff 68 not formed in injection water route 58, it becomes possible to prevent water shutoff 68 water levels for collaborating caused water 44 with water 44 rise.Therefore, by with injection air pocket in water route 58 State floods the entirety of jet 28, the situation that bubble can be prevented to be vented from jet 28, can effectively prevent bubble Plosive.

It should illustrate, in the water closet 10 of this example, because jet 28 is with up and down across the initial water level of water 44 WL1 mode is formed, therefore obtains the action effect of the explanation in foregoing (1).

Then, to for preventing under the striated current from edge water jet 30A, 30B rather than from jet 28 Scheme point illustrates.

Fig. 7 is to schematically show the figure to be formed on the slope of each edge water flowing road 56A, 56B inner bottom surface.Use in detail in this figure Arrow represents the slope from high position to lower position.

In each edge water flowing road 56A, 56B inner bottom surface, provided with each edge water jet 30A, 30B are lateral inwards Inclined slope.Specifically, edge water flowing road 56A inner bottom surface on the right, provided with right hand edge water jet 30A turn into high position, into Turn into the first slope of lower position for the side of branch location 60 of right hand edge water flowing road 56A and left hand edge water flowing road 56B branch point 74.First slope 74 is set in a manner of with being sloped downwardly inwards from right hand edge water jet 30A.

In addition, in left hand edge water flowing road 56B inner bottom surface, turn into high position, injection provided with the foregoing side of branch location 60 Second slope 76 of the lower position turned into the introducing port 64 of water route 58.Second slope 76 is with from left hand edge water jet The mode that 30B is sloped downwardly inwards is set.In addition, in left hand edge water flowing road 56B inner bottom surface, provided with the front end as terminal Position 56Ba turns into high position, injection turns into the 3rd slope 78 of lower position with the introducing port 64 of water route 58.It should illustrate, Each edge water flowing road 56A, 56B branch location 60 are formed with the depressed part 80 to lower recess.

The advantages of being formed more than illustrating.It is contemplated that the supply of the flushing water from flush water supply device 104 terminates, respectively The situation near water level decreasing to each edge water jet 30A, 30B lower edge in edge water flowing road 56A, 56B.Under the situation, The water such as residual water, make-up water on each edge water flowing road 56A, 56B inner bottom surface are by first slope 74, the second slope 76 certainly Recast is easily flowed with lower along the direction away from each edge water jet 30A, 30B.That is, each edge water flowing road 56A, 56B interior bottom Shipwreck on face is with close to each edge water jet 30A, 30B, it is difficult to flows to closestool portions via each edge water jet 30A, 30B In 14.Thus, when the water level decreasing in each edge water flowing road 56A, 56B as status, striated water can be prevented Flowed down from each edge water jet 30A, 30 along the inner surface of closestool portions 14, can effectively prevent closestool caused by toilet flushing Degraded appearance in portions 14.

In addition, injection is configured than each edge water jet 30A, 30B with least a portion of the introducing port 64 of water route 58 Low position.The introducing port 64 of present embodiment is integrally provided in the position lower than each edge water jet 30A, 30B.From other sights Point is set out, and at least a portion of introducing port 64 is configured than the highest order with first slope 74, the inner bottom surface on the second slope 76 The position set low.The introducing port 64 of present embodiment is integrally provided in than the inner bottom surface with first slope 74, the second slope 76 The position that sets low of highest order.More specifically, introducing port 64 is configured in the extreme lower position than the inner bottom surface with first slope 74 Locate more on the lower, and configure with the extreme lower position same position of the inner bottom surface with the second slope 76 at.

Therefore, it is oblique by first slope 74, second during the water level decreasing in each edge water flowing road 56A, 56B Slope 76, the water on each edge water flowing road 56A, 56B inner bottom surface can be made to be easy to imported into injection water supply under Gravitative Loads The introducing port 64 on road 58.Therefore, it is possible to by the water on each edge water flowing road 56A, 56B inner bottom surface via injection water route 58 Discharge, easily reduce and flow to the water in closestool portions 14 via each edge water jet 30A, 30B.As a result, at each edge During water level decreasing in water flowing road 56A, 56B, can more efficiently prevent from striated water from each edge water jet 30A, Inner surfaces of the 30B along closestool portions 14 flows down, and can more efficiently prevent from toilet flushing and cause the outward appearance in closestool portions 14 to become Difference.

Then, the purging method of the closestool portions 14 of use above water closet 10 is illustrated using Fig. 8.

Dirt in closestool portions 14 is flushed in Drainage Division 18, so-called wash by water closet 10 by using the drop of water Fall formula backwashing manner to rinse in closestool portions 14.Pass through the operating portion material of the switch for being initially supplied flushing water, bar etc. Operation, the flushing water in the range of predetermined amount of flow is supplied into the water spray portion 26 of water closet 10 from flush water supply device 104.With Under, the action from the flushing water being initially supplied in the range of predetermined amount of flow untill end is said as once flushing action It is bright.It should illustrate, in the present embodiment, the tap water direct that flush water supply device 104 is pressed by using the water supply of running water The way of supplying water of pressure type supplies flushing water.

The flushing water supplied from flush water supply device 104 is flowed into water spray portion 26 from inflow entrance 54.It is flowed into water spray Flushing water in portion 26 respectively flows through right hand edge water flowing road 56A, left hand edge water flowing road 56B, injection water route 58 (not shown) Inside, respectively from jet 28, each edge water jet 30A, 30B spray.

In addition, in addition, it can be adjusted by the water flowing part 244d of restriction 244 size adjusting from left hand edge Water flowing road 232L top side is separately dispensed into the sendout of the flushing water of left hand edge hole for water spraying 236L and spray-hole 238.

Then, the further feature of water closet 210 is illustrated.

Sometimes remaining in each edge water flowing road 232L, 232R residual water turns into water (the hereinafter referred to as striated of striated Water), it is delivered to the inner surface of closestool portions 214 from each edge hole for water spraying 236L, 236R and flows down.The striated water is not except advising Flowed while then changing the path along the inner surface of closestool portions, also long lasting for flowing down, turning into causes degraded appearance The reason for.Hereinafter, the characteristic point improved to it is illustrated.

Figure 17 is the figure on the slope for schematically showing the inner bottom surface for being formed at each edge water flowing road 232L, 232R.In this figure In, the slope indicated by an arrow from high position to lower position.Each edge water flowing road 232L, 232R inner bottom surface be provided with turn into From each edge hole for water spraying 236L, 236R to inclined slope under inboard whereabouts.

Specifically, in left hand edge water flowing road 232L inner bottom surface, provided with the branch as each edge water flowing road 232L, 232R The side of branch location 242 of point turns into high position, injection turns into the first slope of lower position with the water introducing port 240d of access 240 250.First slope 250 is set by with from left hand edge hole for water spraying 236L in a manner of inclined under the whereabouts of inner side.Edge leads on the right Water route 232R inner bottom surface, provided with right hand edge hole for water spraying 236R as high position, each edge water flowing road 232L, 232R branch position Putting 242 sides turns into the second slope 252 of lower position.Second slope 252 is with from right hand edge hole for water spraying 236R to inboard whereabouts Under inclined mode set.It should illustrate, be formed in each edge water flowing road 232L, 232R branch location 242 to lower recess Depressed part 254.

Using the slope 252,254 of the above, injection is existed with the water introducing port 240d of access 240 at least a portion configuration The position lower than each edge hole for water spraying 236L, 236R.The water introducing port 240 of present embodiment is integrally provided in sprays water than each edge Hole 236L, 236R low position.

The advantages of illustrating the composition of the above.If terminating the supply of the flushing water from flush water supply device 204, except Beyond each edge hole for water spraying 236L, 236R, water in each edge water flowing road 232L, 232R via left hand edge water flowing road 232L water Introducing port 240d and discharged from injection access 240.Here, it is contemplated that under the water level in each edge water flowing road 232L, 232R The situation dropped near each edge hole for water spraying 236L, 236R lower edge.In this condition, remain in each edge water flowing road 232L, Residual water on 232R inner bottom surface can be via the water introducing port positioned at the position lower than each edge hole for water spraying 236L, 236R 240d and discharged from injection access 240, easily reduce via each edge hole for water spraying 236L, 236R being flowed into closestool portions Water in 214.Thus, when the water level decreasing in each edge water flowing road 232L, 232R as status, can prevent Striated water under the inner surface stream of closestool portions 214, can effectively prevent from rinsing just from each edge hole for water spraying 236L, 236R Device causes the degraded appearance in closestool portions.

It should illustrate, " residual water " here includes situation about being formed for the flushing water residual of toilet flushing.In addition, In addition, also include due to toilet flushing and water 228 from Drainage Division 220 discharge after, supplied to store water 228 again The residual water that the make-up water given is formed.

In addition, during water level decreasing in each edge water flowing road 232L, 232R, it is easy to each edge water flowing road Water conservancy first slope 250, the second slope 252 on 232L, 232R inner bottom surface, which are guided under Gravitative Loads to injection, to be connected The water introducing port 240d of path 240.Thereby, it is possible to by the water on each edge water flowing road 232L, 232R inner bottom surface via injection Discharged with access 240, be easily reduced via each edge hole for water spraying 236L, 236R and flow to the water in closestool portions 214.Its As a result, during the water level decreasing in each edge water flowing road 232L, 232R, it can effectively prevent striated water from each side Edge hole for water spraying 236L, 236R can more efficiently prevent from toilet flushing and cause toilet seat under the inner surface stream of closestool portions 214 Degraded appearance in portion.

Here, as shown in figure 15, the water route of left hand edge hole for water spraying 236L sides (top side) will be located at relative to restriction 244 Part 236d is referred to as top side water route part 236d, will be located at water introducing port 240d sides (end side) relative to restriction 244 Water route part 236e is referred to as end side water route part 236e.Now, the water flowing part 244b of restriction 244 bottom surface 244c will begin Side water route part 236d inner bottom surface and end side water route part 236e inner bottom surface are with by along from left hand edge hole for water spraying Face that the lateral water introducing port 240d of 236L are sloped downwardly and smoothly connected mode connects.As shown in figure 16, the bottom surface 244c restriction 244 forming position throughout left hand edge water flowing road 232L water route width whole width range shape Into.The residual water that such restriction 244 has the inner bottom surface that can will flow through left hand edge water flowing road 232L is sprayed water from left hand edge The shape that 236L lateral water introducing port 240d sides in hole guide along direction Pc.

Thus, become residual water be difficult to precipitate and easily with respect to restriction 244 from left hand edge hole for water spraying 236L effluents to Water introducing port 240d sides.Thus, in the case that left hand edge water flowing road 232L forms restriction 244, from each edge water flowing It is easy to discharge flushing water via injection access 240 in road 232L, 232R.As a result, it can effectively prevent striated Water is from each edge hole for water spraying 236L, 236R under the inner surface stream of closestool portions 214.

It should illustrate, from this viewpoint, the bottom surface 244c of restriction 244 is by top side water route part 232d inner bottom surface Connected with end side water route part 232e inner bottom surface in a manner of being connected from the lateral end side level in top, or so that terminal The side mode lower than top side connects.In either case, left hand edge water flowing road 232L can will be flowed through by all having Inner bottom surface on residual water from the shape of left hand edge hole for water spraying 236L lateral water introducing port 240d sides guiding.

In addition, from the viewpoint of action effect as performance, the bottom surface 244c of restriction 244 is in restriction 244 Forming position, throughout the scope formation of a left hand edge water flowing road 232L water route width part.

That is, as it was previously stated, left hand edge water flowing road 232L inner bottom surface, provided with close to injection access 240 Water introducing port 240d and the first slope 250 (reference picture 17) tilted down.Thus, when to left hand edge water flowing road 232L terminal When flushing water in the part 236e of side water route assigns the hydraulic pressure for corresponding to the pressure that supplies water, the flushing in the part 236e of its end side water route Water is easy to swimmingly guide to water introducing port 240d along first slope 250.As a result, it is easier to lead to flushing water from left hand edge Water route 232L is drawn into injection access 240, it is easier to sprays the flushing water of high hydraulic pressure from spray-hole 238.

Then, the further feature of water closet 210 is illustrated.

Figure 18 (a) is the figure for the left hand edge water flowing road 232L for representing the first variation.In detail in this figure, from identical with Figure 15 Viewpoint, left hand edge water flowing road 232L is shown.Compared with Figure 15 example, the restriction 244 of this example is in the following areas not Together, between top side water route part 232d and end side water route part 232e to cut through the fluid stream of these underside areas Dynamic mode forms wall part 244a.It should illustrate, foregoing (A), (B) effect effect are also obtained in the water closet 210 Fruit.

In the case of restriction as presence 244, inventor passes through experimental study, learns bubble easily from spray-hole 238 spray.If so spraying bubble from spray-hole 238, the plosive of bubble can be produced, or discomfort in terms of outward appearance be present Sense, therefore sense of discomfort can be brought to user.

Though the mechanism of this phenomenon is indefinite, following reason can be speculated as.As it was previously stated, as shown in Figure 18 (b), If supplying flushing water W to left hand edge water flowing road 232L, top side water route part 232d is first rinsed water W and is full of.Now, sometimes The non-emptyings of air Ar in the part 232e of end side water route and remain.In the case, turn into from the water flowing part of restriction 244 244b sees the state that air Ar in end side be present.Thus, if flowing into flushing water W via water flowing part 244b with the state End side water route part 232e, then flushing water W flows into injection while the air Ar in the part 232e of end side water route is involved in With access 240.The air being involved in is inferred as to spray as bubble from spray-hole 238.

On the other hand, as shown in figure 15, the restriction 244 of present embodiment is in top side water route part 232d and end side water route Between the 232e of part, formed with wall part 244a in a manner of cutting off via the flow of fluid of these upper-side areas.Such as Figure 16 institutes Show, wall part 244a restriction 244 forming position, it is entirely wide in the water route width throughout left hand edge water flowing road 232L Formed in the range of degree.

Illustrate its advantage.As shown in figure 19, consider that left hand edge water flowing road 232L top side water route part 232d is first rushed Wash water W is full of, the residual air Ar situation in the part 232e of end side water route.In the case, according to present embodiment, into For the state that air Ar has flushing water W is not present in end side in terms of the water flowing part 244b of restriction 244.Thus, exist Even if make under the state flushing water W via water flowing part 244b inflow terminal side water route part 232e, end side water route part Air in 232e is also difficult to be involved in flushing water W, and air difficultly flows into injection access 240.Therefore, lead to even in left hand edge In the case that water route 232L forms restriction 244, it can prevent the bubble from spray-hole 238 from spraying.

In addition, in addition, by forming the wall part 244 of foregoing restriction 244, when to left hand edge water flowing road In 232L during supply flushing water, air Ar be not discharged to the outside from left hand edge water flowing road 232L end side water route part 232e and It is easy to remain.Thus, flushing water W via restriction 244 water flowing part 244b when, its air Ar turns into resistance, thus flows into Flushing water in the part 232e of end side water route becomes to be difficult to spread.As a result, flushing water can be prevented in end side water route portion Divide diffusion in 232e to cause the flow of water to reduce, be easy to tempestuously spray flushing water from spray-hole 238.

It should illustrate, as shown in figure 16, in the forming position of restriction 244, when by left hand edge water flowing road 232L water route When being highly set to H0, the wall part 244a of restriction 244 is so that the height gauge of edge water flowing road 232L interior upper surface From Left Very little H1 is formed as more than 1/2 mode in water route height H0.The wall part 244a of restriction 244 can also be with away from left hand edge The height dimension H1 of water flowing road 232L interior upper surface is formed as water route height H0 more than 3/4 mode.
