Fig. 2 is near the ideograph of amplify observing the flashboard of this embodiment of analysing and observe.

Fig. 3 is the three-dimensional pattern figure of the closet of this embodiment of expression.

In addition, Fig. 2 representes to clean nozzle and is housed in the state in the housing, is equivalent to the A-A sectional view shown in Fig. 1 (a).

Housing 200 has body cover 210 and body base plate 220.Equipment such as local clean function portion are arranged at body base plate 220, cover its top through body cover 210.Body base plate 220 has the portion that is arranged with 223 that forms concavity downwards.Be arranged with portion 223 and be arranged on the part of body base plate 220, tilt to be step-down forwards from the rear.And, be provided with at the leading section of the portion of being arranged with 223 and clean the peristome 223b that nozzle 241 can run through.That is to say, stretch out or retreat thereby clean nozzle 241 can run through this peristome 223b.

On the other hand, as shown in Figure 3, closet 100 105 has recess 103 on basin, and it forms concavity downwards.Recess 103 is formed with the interconnecting part 103b that is communicated with basin 101 at its front end, and it is the same with the portion that is arranged with 223 that is arranged at body base plate 220, tilts for from end 103a forward end (interconnecting part) 103b step-down thereafter.And body base plate 220 is housed inside the state of the recess 103 of closet 100 with the portion of being arranged with 223, is placed on above the basin of closet 100 on 105.Therefore, cleaning nozzle 241 runs through peristome 223b advance and retreat and cleans nozzle 241 and run through interconnecting part 103b advance and retreat and be equal to.

Flashboard 230 is installed on body base plate 220, and its switching is arranged with the peristome 223b of portion 223.Flashboard 230 is set to cover interconnecting part 103b and peristome 223b, and is supported in body base plate 220 by axle with freely rotating.More specifically, flashboard 230 is the center with the axle 228 that is kept by the bearing portion 227 of body base plate 220, is supported in body base plate 220 by axle with freely rotating.

And flashboard 230 has outstanding wall 231, and it extends towards interconnecting part 103b and peristome 223b under closing state.That is, flashboard 230 has outstanding wall 231 with interconnecting part 103b and peristome 223b opposing backside surface.Should give prominence to wall 231 under flashboard 230 closing state, local and peristome 223b butt.That is,, confirm the fastening position of flashboard 230 through outstanding wall 231 and the local butt of peristome 223b.

Body cover 210 has the portion that extends 217 of extending setting to basin 101 the place aheads.As shown in Figure 2, at least a portion that extends portion 217 has got in the basin 101.Therefore, flashboard 230 is provided in the below of the portion of extending 217.That is to say that flashboard 230 has covered the top through the portion of extending 217 under closing state.In other words, flashboard 230 is arranged on the front 217a of the portion of extending 217 and compares on the position of retreating.Therefore, extend the top that portion 217 covers the flashboard 230 that is in closed condition.

Thus, the bearing portion 227 of body base plate 220, the axle 228 that is kept by bearing portion 227, the shaft supporting part 237 (with reference to Fig. 4) that is arranged at flashboard 230 are provided in the below of the portion of extending 217, and extend portion 217 through this and covered the top.In other words, bearing portion 227, axle 228 and shaft supporting part 237 are arranged on the front 217a of the portion of extending 217 and compare on the position of retreating.Therefore, extend the top that portion 217 covers bearing portion 227, axle 228 and shaft supporting part 237.

Thereby the urine that the male sex discharges with the posture of standing is difficult to run into flashboard 230.That is to say, even the urine of discharging row to flashboard 230, also because the top of flashboard 230 is covered by the portion of extending 217, is blocked by the portion of extending 217 so urinate.Therefore, the urine of discharge is difficult to directly run into flashboard 230.In addition and since the top of flashboard 230 be provided in the portion of extending 217 under, so compare with the bottom of flashboard 230, very difficult quilt is directly urinated.

And as shown in Figure 2, bearing portion 227, axle 228 and shaft supporting part 237 are arranged on the top of peristome 223b.That is to say that flashboard 230 is supported in this top by axle with freely rotating.Therefore, bearing portion 227, the axle 228 and shaft supporting part 237 be provided in the portion of extending 217 under.Thereby bearing portion 227, axle 228 and shaft supporting part 237 are compared with the bottom of flashboard 230, and very difficult quilt is directly urinated.

And as shown in Figure 2, flashboard 230 has vertical guide 233 and inclined plane 235 on the surface of basin 101 sides.Vertical guide 233 is arranged on the top of flashboard 230.On the other hand, inclined plane 235 is arranged on the bottom of flashboard 230, and tilts for to retreat to the bottom from top.

In view of the above, though the inclined plane 235 of urinating and on the internal face of basin 101, splashing and being attached to flashboard 230, can be not up along this inclined plane 235 yet.And, even the vertical guide 233 of urinating and on the internal face of basin 101, splashing and being attached to flashboard 230, this also diffluence downwards promptly of urinating.Therefore, even urine is splashed on the internal face of basin 101 and when being attached to flashboard 230, possibility does not flow to bearing portion 227, axle 228 and shaft supporting part 237 basically yet.

In view of the above,, adheres to the toilet-flushing apparatus of this embodiment, so can suppress to produce foreign odor or produce the urine dirt to the axle 228 that axle supports flashboard 230 because can suppressing urine.Therefore, the toilet-flushing apparatus of this embodiment can suppress because of urinating the bad phenomenon that dirt causes that flashboard 230 can't open and close etc.

In addition, between the recess 103 of the portion that is arranged with 223 of body base plate 220 and closet 100, be provided with rubber-like elastic body 107.This elastic body 107 is guaranteed the close property of liquid between the recess 103 of the portion that is arranged with 223 and closet 100 of body base plate 220 when support is arranged with near the peristome 223b of portion 223.That is to say that elastic body 107 can prevent between the recess 103 of the portion that is arranged with 223 and closet 100 of entering body base plates 220 such as urinating.In addition, this elastic body 107 also along the leading edge of body base plate 220 be disposed at closet 100 above 105, with guarantee body base plate 220 and closet 100 top 105 between the close property of liquid, prevent entering such as urine.

And, in illustrated concrete example, though body base plate 220 is provided with bearing portion 227; And flashboard 230 is provided with shaft supporting part 237; But the present invention is not limited thereto, also can on the body base plate, shaft supporting part be set, and bearing portion is set on flashboard.

Fig. 4 is the three-dimensional pattern figure of the mounting structure of expression flashboard and body base plate.

In addition, Fig. 4 (a) is the three-dimensional pattern figure that the expression flashboard is installed on body base plate state before, and Fig. 4 (b) is the three-dimensional pattern figure that the expression flashboard is installed on body base plate state afterwards.

As said about Fig. 2, body base plate 220 has bearing portion 227 above peristome 223b.And, through these bearing portion 227 retainer shafts 228.And an end bent of axle 228 is a hook-type, and through being held on the claw 226 that hangs over body base plate 220.Afterburning member 229 to flashboard 230 application of forces is installed on axle 228.As this reinforcing member 229, for example can enumerate so-called " torsionspring " etc.

On the other hand, flashboard 230 with the upper surface of basin 101 opposition sides, promptly the dorsal part of vertical guide 233 has shaft supporting part 237.This shaft supporting part 237 has the axle hole, and it accepts the axle 228 that is installed on body base plate 220.And at least a portion of shaft supporting part 237 is provided with notch, and it can make axle 228 make a forcible entry into the axle hole.Therefore, can be at the state shown in Fig. 4 (a), promptly be installed under the state of bearing portion 227 of body base plate 220 at axle 228, make axle 228 make a forcible entry into the shaft supporting part 237 of flashboard 230.Thus, 237 pairs of axles 228 that kept by bearing portion 227 of shaft supporting part support, and flashboard 230 is that center steering is supported in body base plate 220 by axle freely with axle 228.

At this moment, be arranged at the jut 239 of flashboard 230 and the wrist 229a butt of afterburning member 229.And this jut 239 turns round with the action of flashboard 230, accepts the load from wrist 229a.That is to say that when flashboard 230 was opened, jut 239 was revolted from the load of wrist 229a and turned round.Therefore, through afterburning member 229 on the direction of closing to flashboard 230 application of forces.

Thereby flashboard 230 can't oneself be opened, but opens through receiving from the power of the clean nozzle 241 that stretches out to basin 101.That is to say that flashboard 230 is that open at the center through being cleaned nozzle 241 and promoting and with axle 228.On the other hand, when clean nozzle 241 is retreated and when being housed in the housing 200, because flashboard 230 do not receive from the power of cleaning nozzle 241, so close through the active force of afterburning member 229.That is to say that flashboard 230 is in the closed condition shown in Fig. 1 (a) under the state that clean nozzle 241 does not stretch out.In view of the above, flashboard 230 can prevent the urine that the user discharges or the deodorization ponding that splashes etc. gets into from peristome 223b and cleans nozzle 241 sides.

Fig. 5 is near the ideograph of amplify observing the flashboard of this embodiment of analysing and observe.

In addition, Fig. 5 representes to clean the state that nozzle has stretched out from housing, is equivalent to the B-B sectional view shown in Fig. 1 (b).

Nozzle unit 240 with clean nozzle 241 at one end portion has nozzle and cleans chamber 245.Nozzle is cleaned chamber 245 can clean the outer surface of cleaning nozzle 241 through the guttation mouth injection water from the portion of setting within it.And nozzle is cleaned chamber 245 can be when clean nozzle 241 be advanced and retreat, and the clean water that the outer surface cleaning is carried out in inhibition disperses.Clean nozzle 241 runs through the clean chamber 245 of this nozzle and stretches out.At this moment, as shown in Figure 5, clean nozzle 241 pushes flashboard 230 and extend out in the basin 101 from the rear.

And cleaning nozzle 241 can be under the state in stretching out in basin 101, from guttation mouth 243 injection waters, is sitting in cleaning the user on the toilet seat " buttocks " etc.At this, the clean glassware for drinking water that sprays from guttation mouth 243 has at " buttocks " etc. and splashes water, or on the internal face of basin 101, splashes the situation of water.Therefore, the situation that exists sewage, dirt etc. to disperse to flashboard 230, but since bearing portion 227, axle 228 and shaft supporting part 237 be provided in the portion of extending 217 under, so sewage, dirt etc. are difficult to run into bearing portion 227, axle 228 and shaft supporting part 237.And, because under the state that flashboard 230 is opened, in basin 101, narrow down, so sewage, dirt etc. are difficult to run into bearing portion 227, axle 228 and shaft supporting part 237 more towards the paths of bearing portion 227, axle 228 and shaft supporting part 237.

In view of the above,, adheres to the toilet-flushing apparatus of this embodiment, so can suppress to produce foreign odor or produce the urine dirt to the axle 228 that axle supports flashboard 230 because can suppressing sewage, dirt etc.Therefore, the toilet-flushing apparatus of this embodiment can suppress because of urinating the bad phenomenon that dirt, dirt etc. cause that flashboard 230 can't open and close etc.

Fig. 6 be observe from the side this embodiment toilet-flushing apparatus analyse and observe ideograph.

In addition, Fig. 6 is equivalent to the A-A sectional view shown in Fig. 1 (a).

As said about Fig. 2, flashboard 230 under closing state, be provided in the portion of extending 217 below, through this extend portion 217 covered the top.Therefore, stand in closet 100 preceding users and under the posture of standing, can't see flashboard 230 basically.

Therefore, the toilet-flushing apparatus of this embodiment is elegant in appearance, can promote appearance design property.And, because the male sex who urinates with stance can't see flashboard 230, so can not expect basically deliberately urinating on the flashboard 230.That is to say that if flashboard 230 has got into user's sight line when urinating, then this user might expect deliberately urinating on the flashboard 230, but, can not cause user's this idea basically for the toilet-flushing apparatus of this embodiment.The possibility of therefore, deliberately urinating on the flashboard 230 is very little.

And, as said about Fig. 2, bearing portion 227, the axle 228 and shaft supporting part 237 be provided in the portion of extending 217 under.Therefore, want deliberately to urinate bearing portion 227, axle 228 and 237 last times of shaft supporting part, need roughly urinate along double dot dash line C shown in Figure 6.But this almost is impossible.Thereby the possibility of deliberately urinating on bearing portion 227, axle 228 and the shaft supporting part 237 is very little.

And, clean the back at " buttocks ", when user's remote controller is indicated etc., can carry out the cleaning of guttation nozzle 241 self.At this moment, heat exchanger 250 does not carry out the heating of water, and reversal valve 292 switches to nozzle and cleans stream 606 transporting water.The water that is transported to the clean stream 606 of nozzle is sprayed to guttation nozzle 241, carries out the cleaning of guttation nozzle 241 thus.

On the other hand, if with respect to the discharge that flow into from inflow entrance 281 in the auxiliary water tank 280, extracted out and little from the discharge of flow export 282 outflows by pump 291, then shown in arrow OF, the water in the auxiliary water tank 280 flow out (overflow water) from outfall 283.This overflow water is directed to the notch 103 of closet 100, through flowing through notch 103 towards pelvic part 101, and carries out the cleaning of notch 103.The overflow water that flows through notch 103 and carried out cleaning falls to pelvic part 101 from opening 103b, and the water with pelvic part 101 when closet 100 drainings flows out.

Below, with reference to Figure 25 the shape of auxiliary water tank 280 is described.

The stereogram of Figure 25 (a) expression auxiliary water tank 280, the vertical view of Figure 25 b () expression auxiliary water tank 280, the I sectional view of Figure 25 (c) expression auxiliary water tank 280I, the J-J sectional view of Figure 25 (d) expression auxiliary water tank 280.Auxiliary water tank 280 has becomes the auxiliary water tank of its shell housing 280a, but is formed with the space of storage of water in the inside of auxiliary water tank housing 280a.The top 280b of auxiliary water tank housing 280a is provided with inflow entrance 281, its joint access pipe arrangement 604, and the outstanding flow export 282 that is provided with in the bottom of 280c in the side, it connects outlet pipe arrangement 605.The bottom surface 280d almost parallel of the inside of auxiliary water tank housing 280a and auxiliary water tank housing 280a dispose flat cowling panel 284, it runs through and is provided with a lot of perforation 284a.Cowling panel 284 constitutes and is the roughly Room 285 the 1st and the Room 286 the 2nd above it of L font with being divided into the cross section in the auxiliary water tank housing 280a, and a lot of perforation 284a is communicated with Room 285 the 1st and Room 286 the 2nd.

In the side 280c of auxiliary water tank housing 280a, with Room the 2nd 286 corresponding parts on offer rectangle outfall 283, it is communicated with outward with auxiliary water tank housing 280a.And, be provided with encirclement plate 287 with the mode side 280c that surrounds outfall 283.Surround removing up and down of plate 287 open, the below is compared outstanding slightly with the bottom surface 280d of auxiliary water tank housing 280a, and is formed with the water route 288 of leading between the 280c of side.

Next, the current in the auxiliary water tank 280 are described.At first flow into Room 285 the 1st via inlet pipe arrangement 604 from the water that inflow entrance 281 flows in the auxiliary water tank housing 280a.Shown in arrow F1, water flows to flow export 282 along the shape of the roughly L font of Room 285 the 1st.

When hygienic washing device carries out guttation from guttation nozzle 241, be connected the pump 291 that exports pipe arrangement 605 downstream, extract the water in the auxiliary water tank housing 280a out from flow export 282 through driving.Compare with the discharge of extracting out from flow export 282, when the discharge that flows into from inflow entrance 281 was big, the water yield that is stored in the auxiliary water tank housing 280a increased, and its water level begins to rise.

Begin to rise if be stored in the water level of the water in the auxiliary water tank housing 280a, then shown in arrow F2, water flows into Room 286 the 2nd via perforation 284a.

286 back water levels further rise again if water flows into Room the 2nd, and then shown in arrow F3, the water in the Room 286 the 2nd flows out outside auxiliary water tank housing 280a from outfall 283.The overflow water that flows out from outfall 283 falls via the guiding water route 288 of below, flows out from guide water way outlet 288a.

At this, shown in Figure 23 (b), auxiliary water tank 280 is configured on the lower house 220 at guttation nozzle 241 and notch 103 rears as stated.And, because the overflow water that flows out from guide water way outlet 288a is directed to notch 103, and flow through notch 103 arrival pelvic parts 101, so can carry out the cleaning of notch 103 thus.

And, since guide water way outlet 288a be configured to be positioned at notch 103 directly over, so be not directed to notch 103 along the overflow waters that fall extremely in the guiding water route 288 with then can not losing its whereabouts flow of water.Thereby, can expect the excellent cleaning performance that the flow of water produced of overflow water.And, be configured to separate outfall 283 and drive division 151 owing to surround plate 287, so can prevent to disperse to drive division 151 sides from the overflow water that outfall 283 is discharged.That is, overflow water can not become the reason of guttation nozzle 241 or drive division 151 side faults.

So, this embodiment constitutes, and the so-called open water tank of configuration is an auxiliary water tank 280 in the water route, carries out the cleaning of the notch 103 of closet 100 through the overflow water from its outflow.That is, implemented following design, the overflow water that will flow out from the open water tank that prevents adverse current effectively is used in the cleaning of the closet notch of making dirty easily.

In addition, can whether irrespectively carry out notch 103 cleanings with hygienic washing device based on the overflow water of this auxiliary water tank 280 at the guttation that carries out guttation nozzle 241.That is to say, when guttation nozzle 241 carries out guttation (, just when driving pump 291), as stated, through with the discharge that flows into greater than the mode of the discharge of in auxiliary water tank housing 280a, extracting out to valve cell 270 water flowings, just can obtain overflow water.And, when guttation nozzle 241 does not carry out guttation when driving pump 291 (, not); Owing in auxiliary water tank housing 280a, do not extract water out; So only through carrying out water flowing, the water level that is stored in the water in the auxiliary water tank housing 280a is risen, can obtain overflow water to valve cell 270.Thereby, make time of valve cell 270 water flowings through adjusting, can suitably regulate the overflow water yield of cleaning notch 103.

Below, describe with reference to the variation of accompanying drawing embodiment of the present invention.In addition, to also mark identical symbol about the identical key element of Figure 23 25 described embodiments, and also suitably omit explanation.

In the variation of this embodiment, be formed with the portion of being arranged with (below be also referred to as " lower house slot part ") 223 on the lower house 220, it is depression downwards corresponding to the shape that should insert notch 103.The below of these lower house slot part 223 covering protection guttation nozzles 241.That is,, prevent to damage guttation nozzle 241 because of hygienic washing device is dropped when closet 100 is pulled down hygienic washing device and carry etc.

Disposing elastic body (below be also referred to as " sealing mat ") 107 between lower house slot part 223 and the notch 103, to keep the watertightness between them.But; When on lower house 220, being formed with this lower house slot part 223; Sewage splashes at pelvic part 101 during guttation nozzle 241 guttations, or closet 100 the draining obstructions takes place and the water level of pelvic part 101 when rising etc., and sewage might get into lower house slot part 223 from opening 103b.If sewage gets into and the lower house slot part 223 of having made dirty, then owing to its darker shape, the user is difficult to clean through people's manual task.

Therefore, the toilet-flushing apparatus of this embodiment variation constitutes, and is used for preventing the auxiliary water tank 208 of sealing adverse current in the configuration of the rear of guttation nozzle 241 and lower house slot part 223, will be directed into lower house slot part 223 from the overflow water that auxiliary water tank 280 flows out.That is, clean lower house slot part 223 through the overflow water that flows out from this auxiliary water tank 280.The overflow water that flows through lower house slot part 223 and carried out cleaning flows into pelvic part 101 from opening 103b, and the water with pelvic part 101 when closet 100 drainings falls.

Below, describe with reference to accompanying drawing other variation embodiment of the present invention.In addition, to also mark identical symbol about the identical key element of the described embodiment in Figure 23～26, and also suitably omit explanation.

Figure 27 (a) is the pattern arranged figure of auxiliary water tank 680 on body base plate 620 of the toilet-flushing apparatus of other variation of this embodiment of expression, and Figure 27 (b) is the ideograph of expression from the current of auxiliary water tank 680 outflows.

Figure 28 is shape and the ideograph of current of the employed auxiliary water tank 680 of toilet-flushing apparatus of expression this embodiment other variation.

At first; Shown in figure 27; With the same about the described embodiment of Figure 26; Constitute in depression on the body base plate (below be also referred to as " lower house ") 620 and be provided with the portion of being arranged with (below be also referred to as " lower house slot part "), clean lower house slot part 623 through the overflow water that flows out from auxiliary water tank 680.In the variation of this embodiment, auxiliary water tank 680 is configured in the side of lower house slot part 623 (and not shown guttation nozzle 241).Because with the relation of closet 100 front and back sizes, and can't auxiliary water tank 680 be configured in lower house slot part 623 (and guttation nozzle 241) rear the time,, also can clean lower house slot part 623 even import overflow waters from the auxiliary water tank 680 that so is configured in the side.

Below, with reference to Figure 28 the structure of auxiliary water tank 680 is described.

The stereogram of Figure 28 (a) expression auxiliary water tank 680; The vertical view of Figure 28 (b) expression auxiliary water tank 680; The front view of Figure 28 (c) expression auxiliary water tank 680, the right side view of Figure 28 (d) expression auxiliary water tank 680, the K-K sectional view of Figure 28 (e) expression auxiliary water tank 680.

Auxiliary water tank 680 has becomes the auxiliary water tank of its shell housing 680a, but is formed with the space of storage of water in the inside of auxiliary water tank housing 680a.On auxiliary water tank housing 680a, offer inflow entrance 681 on the 680b, its water that inlet pipe arrangement 604 is supplied with flows into.And 608d goes up the outstanding flow export 682 that is provided with below, and it connects outlet pipe arrangement 605.Set inside at auxiliary water tank housing 680a has dividing wall 684, and it marks off upper space 685 and lower space 686.

In the side 680c of auxiliary water tank housing 680a, with upper space 685 corresponding parts on offer rectangle outfall 683, it is communicated with outward with auxiliary water tank housing 680a.And 680c is along the outstanding blade of a sword portion 687 that is provided with of the periphery of outfall 683 from the side.

Next, the current in the auxiliary water tank 680 are described.Shown in arrow F4, cause its flow of water to weaken from water and dividing wall 684 collisions that inflow entrance 681 flows in the auxiliary water tank housing 680a via inlet pipe arrangement 604.Because dividing wall 684 is bent to form under inflow entrance 681, and along with tilting slightly, so shown in arrow F5, the water of inflow 685 flows to lower space 686 along this shape from upper space sinuously near front end.

When hygienic washing device carries out guttation from the guttation nozzle, be connected the pump 291 that exports pipe arrangement 605 downstream, shown in arrow F6, extract the water in the auxiliary water tank housing 680a out from flow export 682 through driving.Compare with the discharge of extracting out from flow export 682, when the discharge that flows into from inflow entrance 681 was big, the water yield that is stored in the auxiliary water tank housing 680a increased, and its water level begins to rise.

If the water level of the water in the auxiliary water tank housing 680a begins to rise, then shown in arrow F7, water flows out (overflow) from outfall 683 outside auxiliary water tank housing 680a.From overflow water whereabouts that outfall 683 flows out and the lower house slot part 623 that is directed to the below.

So, even auxiliary water tank 680 is being configured in this variation of lower house slot part 623 sides, also can clean lower house slot part 623 through overflow water.And, give prominence to the blade of a sword portion 687 that is provided with from the overflow water utilization that outfall 683 flows out along outfall 683 peripheries, fall downwards from the position of leaving side 680c slightly.Thereby, even in the time must the side 680c of auxiliary water tank housing 680a being arranged on the position of leaving end, lower house slot part 623 side, also can overflow water be imported lower house slot part 623 through blade of a sword portion 687.

Below, describe with reference to the toilet-flushing apparatus of accompanying drawing another other embodiment of the present invention.In addition, in this embodiment, mobile the describing of the overflow water of mainly portion that is arranged with 223 through housing 200 being discharged etc.

Figure 29 be observe from the top another other embodiment of the present invention the body base plate overlook ideograph.

As previously mentioned; With respect to the discharge that flows into from inflow entrance 281 in the water tanks (below be also referred to as " open water tank ") 280; By clean with pump 291 extract out and the discharge that flows out from flow export 282 relatively than hour; The water level that is stored in the water in the open water tank 280 rises, and shown in arrow OF, flows out from outfall (below be also referred to as " overfall ") 283 as surplus water.As the back specified, this surplus water was discharged in the basin 101 of closet 100, and the water in basin 101 is discharged from when closet 100 drainings.

The water that is discharged in the basin 101 is not only the surplus water from overfall 283.For example, make the water cleaned after nozzle 241 cleans guttation mouth 243 (preceding cleaning) before stretching out from housing 200, will clean water after nozzle 241 cleans guttation mouth 243 (afterwash) after being housed in the housing 200 etc. and also be discharged in the basin 101 of closet 100.And the water that when cleaning nozzle 241 advance and retreat, cleans its housing (housing is cleaned) also is discharged in the basin 101 of closet 100.And the dew that the generations such as functional part of function portion are cleaned in the part that is built in housing 200 also is discharged in the basin 101 of closet 100.So, with the water that produces in the housing 200, the basin 101 interior water that promptly are discharged to closet 100 are called " draining " in present specification.

Shown in figure 29, body base plate 220 has the portion that is arranged with 223 that forms concavity downwards.Be arranged with portion 223 and be arranged on the part of body base plate 220, and tilt for from end 223a thereafter to peristome (below be also referred to as " leading section ") 223b step-down.On the other hand, as shown in Figure 3, closet 100 105 has recess 103 in the above, and it forms concavity downwards.Recess 103 forms with basin 101 and is communicated with, and it is the same with the portion that is arranged with 223 that is arranged at body base plate 220, tilts for from end 103a forward end 103b step-down thereafter.And body base plate 220 is housed inside the state of the recess 103 of closet 100 with the portion of being arranged with 223, be placed on closet 100 top 105 on.

As previously mentioned; Because the portion that is arranged with 223 of body base plate 220 forms concavity downwards; And inclination is from rearward end 223a forward end 223b step-down, so arrow shown in figure 29 can be discharged in basin 101 and is arranged on the draining that equipment produced in the housing 200.That is to say, be arranged with portion 223 and play a role that it is discharged and is arranged on the draining that equipment produced in the housing 200 in basin 101 as the draining road.

Be arranged with portion 223 and be provided with outflow flow of water inhibition plate (prominent wall) 224, it suppresses from housing 200 inside to the draining flow of water of outside discharge.That is, prominent wall 224 can weaken from the draining flow of water of the rearward end 223a effluent forward end 223b side of the portion of being arranged with 223.And the leading section 223b that is arranged with portion 223 is provided with notch 225, and it forms backward that end 223a retreats.In addition, prominent wall 224 both can be not make tabular that water passes through, and also can be seam shape, the netted or cellular of the water yield of the prominent wall 224 of restricted passage.

The draining that equipment produced that is arranged in the housing 200 flows to the leading section 223b that is arranged with portion 223, and collides with prominent wall 224.Afterwards, arrow shown in figure 29 is suppressed the both sides of back through prominent wall 224 with draining after 224 collisions of prominent wall in the flow of water.The water of two rear flank through prominent wall 224 is discharged in the basin 101 via notch 225 under the repressed state of the flow of water.

In view of the above, because the drainings that equipment produced that are arranged in the housing 200 are discharged in the basin 101, accumulate water 110 under the repressed state of the flow of water so be discharged to along the internal face of basin 101.Therefore, though the toilet-flushing apparatus of this embodiment at drain discharge more for a long time, also can suppress draining and directly fall into and accumulate water 110 and splash water.And, because being discharged to along the internal face of basin 101, draining accumulates water 110, so can being suppressed on the internal face of basin 101, the toilet-flushing apparatus of this embodiment splashes water.In addition, " splashing water " of indication not only refers to by accumulating the water that splashes that water 110 causes in this embodiment, also comprises the water that splashes that internal face because of basin 101 causes.

In addition, in the portion of being arranged with 223, be equipped with at least a portion of the clean nozzles 241 of advance and retreat inside and outside basin 101.And, support nozzle unit through the support portion 223d that is arranged in the portion of being arranged with 223 with this clean nozzle 241.

Below, describe near the leading section 223b to the portion of being arranged with 223 in more detail.

Figure 30 is near the ideograph of leading section of the portion that is arranged with of expression body base plate.Figure 30 a () is near the ideograph of observing from the side the leading section of the portion that is arranged with of body base plate of analysing and observe, and is equivalent to L-L sectional view shown in Figure 29.Figure 30 (b) is near the ideograph of analysing and observe the leading section of the portion that is arranged with of top observation body base plate, is equivalent to the M-M sectional view shown in Figure 30 a ().

Figure 31 be observe from the side this embodiment toilet-flushing apparatus analyse and observe ideograph.In addition, Figure 31 is equivalent to the A-A sectional view shown in Fig. 1 (a).

As said about Figure 29, be arranged with portion 223 and be provided with prominent wall 224, it suppresses from housing 200 inside to the draining flow of water of outside discharge.Shown in Figure 30 (b), prominent wall 224 forms with the wall thickness of central portion compares the attenuation slightly of the wall thickness at both ends.That is to say that the back 224a of prominent wall 224 tilts slightly, compares two-end part in the place ahead with central portion.Therefore, be arranged in the housing 200 the draining that equipment produced with prominent wall 224 collisions after, can not cross prominent wall 224, but flow to the both ends of prominent wall 224 smoothly.At this moment, draining suppresses the flow of water through prominent wall 224.

Afterwards, the draining through next door, prominent wall 224 both ends flows to notch 225.At this, owing to prominent wall 224 is arranged near the leading section 223b, promptly near the notch 225, so draining flows to notch 225 under the repressed state of the flow of water.Relative therewith, in the time of near prominent wall 224 is arranged on rearward end 223a,, also might, draining increase once more before arriving notch 225 even the draining flow of water is suppressed by prominent wall 224.Therefore, more preferably prominent wall 224 is arranged near the leading section 223b, promptly near the notch 225.

And, tilt for from rearward end 223a forward end 223b step-down owing to be arranged with portion 223, so draining can not be trapped near the prominent wall 224, but flow to notch 225.And this draining is discharged in the basin 101 of closet 100 via notch 225.

At this, shown in Figure 30 a (), the leading section 223b that is arranged with portion 223 is not outstanding in basin 101 from basin internal face 101a.On the other hand, as said about Figure 29, notch 225 forms backward at the leading section 223b of the portion of being arranged with 223 that end 223a retreats.Therefore, notch 225 is the same with leading section 223b, and is not outstanding in basin 101 from basin internal face 101a.Therefore, the arrow shown in Figure 30 a () is discharged in the basin 101 along basin internal face 101a through the draining behind the notch 225.

And, flashboard 221 is installed, so that cover the leading section 223b that is arranged with portion 223 on body base plate 220.As said about Fig. 4, through spring etc. on closing direction to flashboard 221 application of forces.And flashboard 221 has the jut 221a that under closing state, gives prominence to the portion of being arranged with 223.This jut 221a is under flashboard 221 closing state, with the leading section 223b butt of the portion of being arranged with 223.That is,, confirm the fastening position of flashboard 221 through jut 221a and the leading section 223b butt that is arranged with portion 223.Therefore, shown in Figure 30 (a) and Figure 30 (b), the rearward end 225a partition distance of the bottom of flashboard 221 and notch 225.Thereby even flashboard 221 has cut out, water vent can be discharged in the basin 101 via notch 225.

And, even because flashboard 221 has cut out, and water vent can pass through notch 225, so draining is difficult to contact with flashboard 221.Therefore, flashboard 221 receives the power of draining and the possibility opened is very little under closing state.Thereby flashboard 221 is very little with the possibility that the leading section 223b that is arranged with portion 223 produces impact sound.

If more specifically describe, then when draining touches flashboard 221 and applies power, owing to flashboard 221 is applied on closing direction effectively, so might open and close repeatedly because of the draining flow of water.Because when flashboard 221 opens and closes repeatedly, jut 221a and leading section 223b be butt repeatedly, so might when butt at every turn, produce offending sound (impact sound).Relative therewith, because in the toilet-flushing apparatus of this embodiment, draining is very little with the possibility that flashboard 221 contacts, so it is very little to produce the possibility of this impact sound.

And the draining arrow N shown in figure 31 after having been suppressed the flow of water and passed through notch 225 by the wall 224 of dash forward is discharged to along basin internal face 101a and accumulates water 110 as deodorization ponding.And as previously mentioned, the leading section 223b and the notch 225 that are arranged with portion 223 are not outstanding in basin 101 from basin internal face 101a.Therefore, even when near the basin internal face 101a the leading section 223b of the portion of being arranged with 223 is arranged on the vertical, arrow N shown in figure 31, water vent are discharged to along basin internal face 101a and accumulate water 110.

In view of the above, though at drain discharge more for a long time, also can suppress draining and directly fall into and accumulate water 110 and splash water.And, because draining is discharged to along basin internal face 101a and accumulates water 110,, the toilet-flushing apparatus of this embodiment splashes water so can being suppressed on the basin internal face 101a.And, directly fall to and accumulate water 110 owing to can suppress draining, directly fall to the drowning sound that produces when accumulating water 110 so can suppress draining.

Relative therewith, when not being arranged with when prominent wall 224 is set in the portion 223, arrow O shown in figure 31 is arranged on drainings that equipment produced in the housing 200 and might directly falls to and accumulate water 110.Perhaps, arrow P shown in figure 31, the draining that equipment produced that is arranged in the housing 200 might not be along basin internal face 101a, but falls to basin internal face 101a.Arrow O or arrow P shown in figure 31, the draining of discharging from the portion of being arranged with 223 might splash water when falling to and accumulating water 110 or basin internal face 101a.If draining splashes water, then this water that splashes might be attached to the buttocks that is sitting in the user on the toilet seat etc., and is therefore unsatisfactory.And, when directly falling to, draining can produce the sound that falls into water when accumulating water 110, and therefore unsatisfactory.

Below, with reference to accompanying drawing the relation of cleaning nozzle 241 and draining is described.

Figure 32 is near the ideograph of representing to have accommodated the leading section of the portion that is arranged with of state of clean nozzle of analysing and observe.

In addition, Figure 32 is equivalent to the A-A sectional view shown in Fig. 1 (a).

The nozzle unit 240 of this embodiment has clean nozzle 241, and at one end portion has the clean chamber 245 of nozzle.Nozzle is cleaned chamber 245 can spray the water of being supplied with by reversal valve 292 through the guttation mouth from the portion of setting within it, and cleans the outer surface (housing is cleaned) of cleaning nozzle 241.And nozzle is cleaned chamber 245 and can when cleaning nozzle 241 advance and retreat, be dispersed by the clean water of inhibition cleaning outer surface.Cleaning nozzle 241 runs through this nozzle and cleans chamber 245 and stretch out or retreat.

Carry out at least a portion of the clean clean water of housing, perhaps preferred its most of portion that is arranged with 223 that falls to body base plate 220 as " draining " from the peristome 245a that is arranged on clean 245 bottoms, chamber of nozzle.At this moment, shown in figure 32, compare with prominent wall 224 and be configured in rearward end 223a side because nozzle is cleaned the peristome 245a of chamber 245, fall to rearward end 223a side so compare with prominent wall 224 through the draining behind the peristome 245a.

On the other hand, the nozzle unit 240 of this embodiment can run through the clean chamber 245 of nozzle and before stretching out, clean the cleaning (preceding cleaning) of cleaning guttation mouth 243 parts of nozzle 241 in the chamber 245 at this nozzle at clean nozzle 241.Identical therewith, nozzle unit 240 can run through nozzle at clean nozzle 241 to be cleaned chamber 245 and after retreating, cleans the cleaning (afterwash) of cleaning guttation mouth 243 parts of nozzle 241 in the chamber 245 at this nozzle.

So, clean before carrying out and afterwash after at least a portion of clean water, perhaps preferred it is most of with to carry out clean water that housing cleans the same, after passing through peristome 245a, compares the portion that is arranged with 223 that falls to rearward end 223a side with prominent wall 224.

Afterwards, compare the draining that falls to rearward end 223a side with prominent wall 224 and suppressed the flow of water by prominent wall 224.As said about Figure 30, suppressed the draining of the flow of water by the wall 224 of dashing forward and passed through notch 225, be discharged to along basin internal face 101a and accumulate water 110.Therefore, though carry out that housing is cleaned, the drain discharge of clean water after the preceding cleaning, afterwash more for a long time, also can suppress draining and directly fall into and accumulate water 110 and splash water.And, because above-mentioned draining is discharged to along basin internal face 101a and accumulates water 110,, the toilet-flushing apparatus of this embodiment splashes water so can being suppressed on the basin internal face 101a.

In addition, shown in figure 32, between the recess 103 of the portion that is arranged with 223 of body base plate 220 and closet 100, be provided with rubber-like elastic body 107.This elastic body 107 is guaranteed the close property of liquid between the recess 103 of the portion that is arranged with 223 and closet 100 of body base plate 220 when support is arranged with the leading section 223b of portion 223.That is to say that elastic body 107 prevents between the recess 103 of the portion that is arranged with 223 and closet 100 of entering body base plates 220 such as urinating.In addition, this elastic body 107 also along the leading edge of body base plate 220 be disposed at closet 100 above 105, with guarantee body base plate 220 and closet 100 top 105 between the close property of liquid, prevent entering such as urine.

Figure 33 is near the ideograph of analysing and observe the leading section of the expression portion that is arranged with that cleans the state that nozzle stretched out from housing.

In addition, Figure 33 is equivalent to the A-A sectional view shown in Fig. 1 (a).

Shown in figure 33, clean nozzle 241 and run through nozzle and clean chamber 245 and stretch out, but jack-up flashboard 221 and extending out in the basin 101.At this moment; Though the bottom of the portion that is arranged with 223 of at least a portion adjacent body base plate 220 of clean nozzle 241; But because leading section 223b is provided with notch 225, so fully guaranteed the distance between the rearward end 225a of clean nozzle 241 and notch 225 about the discharge of draining.

Therefore, the draining that equipment produced that is arranged in the housing 200 is very little with the possibility that clean nozzle 241 contacts.And, because the prominent wall 224 that is set in the portion of being arranged with 223 of draining has suppressed the flow of water, so rapidly fly out and the possibility that contacts with clean nozzle 241 is very little from the portion of being arranged with 223.Therefore, draining falls to along clean nozzle 241 accumulates water 110, or it is very little to fall to the possibility of basin internal face 110a.Thus, the toilet-flushing apparatus of this embodiment can suppress to splash water along the draining of cleaning nozzle 241 accumulating on water 110 or the basin internal face 110a.

Relative therewith, when prominent wall 224, notch 225 were not set in the portion of being arranged with 223, draining might contact with clean nozzle 241.Might postpone to the leading section side (guttation mouth 243 sides) of cleaning nozzle 241 with the draining after clean nozzle 241 contacts.Because the leading section that is in the clean nozzle 241 of the state of stretching out is configured in the upside that accumulates water 110, accumulate water 110 so might directly fall to along the draining of cleaning nozzle 241.If draining directly falls to and accumulates water 110 and splash water, then this water that splashes might be attached to the buttocks that is sitting in the user on the toilet seat etc., and is therefore unsatisfactory.

Below, with reference to accompanying drawing the moment that " draining " is discharged from is described.

Figure 34 is the time diagram of an example of action of the toilet-flushing apparatus of this embodiment of expression.

Whether chart (A) expression seat formula sensor 215 senses the state that the user is seated at toilet seat, the open and-shut mode of the electromagnetic valve 274 of chart (B) expression feed water valve unit 270.The driving condition with pump 291 is cleaned in chart (C) expression, and the position of nozzle 241 is cleaned in chart (D) expression, the guttation position of chart (E) expression reversal valve 292.
