The forward section (12) comprises a base (20) tilted towards the second section (14), flowing into the second section (14) with no separating wall and with the urine draining first opening (26) set in said base, thereby securing a reliable separation of urine and faeces while at the same time permitting problem-free cleaning of the urine section.

Description

WC pans

The present invention relates to a kind of WC pans, in order to discharge dung urine respectively, it have one that play urine district effect and have a proparea of leading to first opening first outlet opening and that can be closed where necessary and one and play second back zone effect, that lead to second outlet opening, stool district, the degree of depth in wherein said proparea is less than the degree of depth of back zone.

Usually, from WC pans or lavatory urinal, discharge dung urine together.Thereby such shortcoming occurs, but promptly perhaps the part of the twice laid in the excreta of lavatory and part that can not twice laid are fed to pipeline together or with it with mixing.

For avoiding this defective, as everyone knows by one next door with WC pans or lavatory urinal be divided into two zones and thereby spaced apart, wherein specified a back zone that is used to defecate and a proparea that is used to urinate, thereby can carry out parted hair discharge.For example, from FR2674881A1 or WO92/190824, known corresponding WC pans.

The shortcoming of this corresponding partition WC pans is the next door, and it not only needs frequent cleaning, and aspect process technology trouble is arranged also.Because open on the direction upwards partially at WC pans in the next door between proparea and the back zone, so the distance between next door and the people that goes to toilet is smaller, the result makes the people uncomfortable.

Because partially, it is bigger to limit urinate the in other words WC pans face in district of proparea, thereby needs more flushing water on the next door, these flushing waters are discharged from by extending the preceding outlet opening of coming from the urine district.For fear of this shortcoming, there is such feasible program, promptly the next door is equipped with a breach (FR2674881A1).But thus one, corresponding WC pans is more bothersome when mould is made.

Problem of the present invention is so to improve the WC pans of the above-mentioned type, promptly realizes the reliable separation of dung urine by simple measure on the structure, thereby can discharge dung urine apart from each other smoothly.In addition, urinate the in other words water supply volume in district of flushing proparea can reduce, and wherein perhaps can be simultaneously these water be used to clean the district of defecating in other words, back zone.

In order to finish above-mentioned problem, the present invention has mainly proposed, that extend towards WC pans second district obliquely by one in first district and limit from the protuberance wall of bowl rim extension to the bottom surface, first opening that this bottom surface does not carry out the transition to second district with having the next door and discharges urine is positioned on this bottom surface, and first opening is especially smooth or extend in the flat bottom surface zone basically at one.

With known systems differently, between urine district and stool district not towards next door that the toilet opening extends.Thereby first district of WC pans gently carries out the transition to second district.As a result, the surface that limits first district is compared less with the isolation toilet in band next door.In addition, owing to there is not the next door, also produced such advantage, the water that promptly cleans the proparea can flow in the back zone, cleans so that also be used to.In this case, close first opening that leads to first outlet opening.This can carry out automatically, exactly is to carry out in this case, does not promptly use corresponding toilet or does not carry out the water flushing.In other words, can realize getting in touch between the closure of WC pans parts such as cushion or flusher and sealing first opening.

Described opening itself extends in the saddle type bottom section in urine district,, when switch is closed, has guaranteed that liquid is not deposited in the bottom zone here.Exactly, liquid always flows into the stool district.In other words, should align bottom surface or carry out the transition to the bottom surface of the closure of opening.

Do not need recess or tangible pit to opening and on bottom surface, WC pans proparea in order to ensure the water conservancy diversion of helping a small child urinate by holding his legs apart reliably, in an improvement project of the present invention, stipulated, the bottom surface has structure such as the rib-like or the parting bead shape projection of liquid being guided into first opening, and they also extend on the wall.

But, especially stipulated following measure, promptly rib-like or parting bead shape projection from first opening and preferably with it the compartment of terrain be radial extension.Thereby, for example can form five rib or parting beads that are radial extension, wherein two edges turn to the transition region of WC pans back zone to extend, and parting bead or rib extend along the toilet longitudinal section that turns to the proparea, and two other rib or parting bead extend between above-mentioned two.In this case, parting bead shape or rib-like projection have especially 10 millimeters-15 millimeters width b or especially 1.0 millimeters-4.0 millimeters height, and its center rib or parting bead can dwindle towards its end.

Bottom surface itself can be in the WC pans longitudinal section evenly reduces the ground diagonally extending continuously to second district, wherein especially select one 5 °-20 ° and 8 °-10 ° angle γ especially.Thus one, the liquid that arrives the toilet proparea flows along the bottom surface more lentamente as urine, thereby depends on that especially the bottom surface realized flow direction first opening structurally, and liquid does not arrive second district as urinating.

So obtained in proparea and the toilet best design of helping a small child urinate by holding his legs apart and guiding first opening into that is attached thereto, promptly the wall in first district is made up of the different part of radius of curvature.In this case, wall have along the longitudinal section of WC pans one that extend at the edge and have a radius of curvature R ₁First and one that carry out the transition to the bottom surface and have a radius of curvature R ₂Second portion, R wherein ₁" R ₂, R especially ₁Be 250 millimeters-300 millimeters, R ₂It is 100 millimeters-120 millimeters.In the varying cross-section of WC pans, respective diameters is successively decreased towards opening from the WC pans proparea, and thus one, facilitated the liquid that flows to opening slowly to flow.

First opening of discharging urine should and perhaps also have an odour seal portion with a closure sealing.The latter can be made of an inserts that can take out and that preferably be filled with sealing fluid.

Perhaps, first outlet opening or the odour seal portion that feed first opening can link to each other with an exhaust device, so that fully discharge the liquid of piling up.

Especially suggestion, in first opening even a liftable closure member, WC pans or an inserts are closed relatively for it.In this case, inserts entirely carries out the transition to the bottom surface in first district at the edge that the toilet side is extended.Have the edge that a closure member around the edge can be attached on the inserts or directly be close to WC pans first opening, first opening extend first district urinate in other words the district in.

Have coaxial the extending in first opening of closure member of a mushroom-shaped geometry itself, wherein said inserts or a seal extend between closure member and the edge of opening, so that guarantee that when opening is closed closure member and WC pans are fully isolated.Thus one, when cleaning the proparea, liquid does not flow in the corresponding outlet opening through first opening.

Described closure member can have the breach such as the hole of radially extending, and their transition are the central cavity such as the blind hole that forward first outlet opening to.If lift closure member, then liquid can flow to first outlet opening by radial hole and blind hole as urine.Perhaps, the closure member with a cylindrical part so extends, and promptly spaced apart with the inwall of the inwall of first opening or its lining seal, when the result lifted at closure member, liquid also can flow away.

As mentioned above, closure member preferably has a mushroom-shaped geometry, it have by convex surfaces protrude into the outer part of first opening, described surface is projecting inward outside the bottom surface at regional area at least when closure member seals first opening.

Perhaps, have such possibility, first opening that promptly is also referred to as the urine closure has an inserts and the orifice plate that can support that is mesh plate form with rotating to it, they can according to its mutual alignment open or close first opening.

As mentioned above, when not using WC pans or washing, the proparea urinate in other words the district first opening be closed.In this case, the cushion that covers the WC pans edge does not bear body weight and/or when the operation flusher, closure member is in the position of sealing first opening.For this reason, can be as operating closure member by a bar or a stay cord that links to each other with cushion or flusher mechanically and for example, so that its lifting.In addition, so wash by water, depend on that promptly mode of occupation ground carries out water continuously and enters the district of defecating in other words, back zone, and do not carry out or regularly carry out that water enters the proparea or urine is distinguished.

So getting in touch of complementary design flusher and closure member promptly under the situation that closure member lifts, can't be operated the former.

Not only the accessory rights claim, therefrom obtain having obtained other details of the present invention, advantage and feature in the technical characterictic (separately and/or in combination), and from following explanation, obtained other details of the present invention, advantage and feature to the preferred embodiment from accompanying drawing, seen.Wherein:

In the drawings, just show to principle the WC pans 10 that forms by the present invention, this WC pans produces the effect of isolating toilet, therefore discharges dung urine respectively.For this reason, this WC pans or lavatory urinal 10 have a proparea 12 and a back zone 14.The proparea of WC pans 10 be used for collecting urine and thereby become the urine district, and in the back zone, collect and discharge stool, exactly become odour seal portion elbow-shaped and that carry out the transition to an outlet opening to discharge by one.

Proparea 12 has one less than back zone 14 degree of depth T _FDegree of depth T _u, unlike the prior art, proparea 12 does not separate by next door or end difference with back zone 14.From this moment, proparea 12 directly carries out the transition to back zone 14 by a rib 18.

Proparea 12 has a smooth or flat bottom surface 20 as far as possible, and this bottom surface stably carries out the transition to a wall that ends at 24 places, WC pans 10 edges.In this case, as illustrated in fig. 7, the internal face of WC pans 10 has the part that radius of curvature has nothing in common with each other.In addition, Fig. 7 shows a longitudinal section of WC pans 10.

In the WC pans longitudinal section, see ground, in other words in the zone of the line 27 of Fig. 9, have to wall 22 rough segmentations one that carry out the transition to bottom surface 20 and have a radius of curvature R ₂ Central portion 25, this radius of curvature is especially between 100 millimeters-120 millimeters.In vertically extending fringe area 24, wall 22 has a radius of curvature R between 250 millimeters-300 millimeters ₁, this radius of curvature carries out the transition to central portion 25.

Bottom surface 20 reduces towards second district 14 continuously or basically continuously obliquely, wherein selects that a relative horizontal plane extends obliquely and equals 5 °-20 ° and 8 °-10 ° angle of inclination γ preferably.This is in the vertical cutting plane of WC pans 10.

Intercepting line A-A, B-B in Fig. 9,10,11,31 beginning ground have a consistent as far as possible radius of curvature respectively to the wall 22 in the proparea of WC pans 10 (urine district 12) from the fringe area, and wherein in each cross section, radius of curvature is successively decreased towards opening 25.Therefore, the radius of curvature R of the wall 22 in intercepting line A-A zone 33 _AAdd up to 170 millimeters-210 millimeters, and the radius of curvature R of the wall 22 in intercepting line B-B zone 35 _BAdd up to 130 millimeters-160 millimeters.In addition, people can see from the contrast of the sectional view of Figure 10 and Figure 12 that wall 22 carries out the transition to one at least towards the inner ring cavity 37 that opens wide of WC pans outside longitudinal section (line 27), supply flushing water by this ring cavity.

Shown in the vertical view of Fig. 2, proparea 12 or urine district have an opening 26, and this opening can be closed by a closure member 28.The ground that has no truck with, radial rib shape or parting bead shape projection 30,32,34,36,38 are extended in the past from opening 26, and they can extend to the top edge district of wall 22 always.Corresponding parting bead or rib 30,32,34,36,38 are guided the liquid that arrives proparea 12 into opening 26, so that discharge by an outlet opening 14, this outlet opening can link to each other with an exhaust device such as vacuum exhaust device.

Can see from the part of Fig. 3,4 WC pans wall that projection 34 of extending along vertical central plane and rib 30,32,34,36,38 have and be about 2 millimeters-3 millimeters and preferably 2.5 millimeters height h and 10 millimeters-15 millimeters and especially be about 12 millimeters width b.In addition, the end that can be called as the projection 30,32,36,38 of side parting bead at least is diminishing, shown in the vertical view of Fig. 2.

20 stool lateral edges 18 extends along the bottom surface also to be noted that projection 30,38 in the stool side.

What deserves to be mentioned is, especially on the one hand by the interior geometry in proparea 12 and on the other hand by for example being the preceding plot structure of rib or parting bead 30,32,34,36,38 shapes, guaranteed that the urine of falling arrives opening 26 and thereby arrival outlet opening 40 in the proparea.

In the stool side, bottom surface 20 stably carries out the transition to the part that limits odour seal portion 16 of back zone 14, and does not need similar structures such as one next door or end difference.

Bottom surface 20 has the trend of planar shaped or slight concave in opening 26 zones, its split shed 26 itself has constituted described and preferably closed recess.If sealing opening 26, then liquid that can not is deposited on the bottom surface 20, thereby can successfully wash away.

Fig. 5 shows the embodiment of the closure member 42 of a sealing opening 26.Form or replenish ground as an alternative, an odour seal inserts can extend in the opening 26, as shown in Figure 6.

Odour seal inserts 44 is incorporated in the opening 26 removedly and has and resembles the

ring cavity

46,48 that is communicated with the bend pipe, and wherein inner chamber 48 is communicated with opening 28 or outlet opening 40, and the proparea that exocoel 46 transits directly to WC pans 10 is bottom surface 20.In addition, a sealing fluid of representing with label 50 such as extraordinary oil level are in odour seal portion 44, and these sealing fluids are lighter than the urine that floats in the odour seal portion 44.In the WC pans side, cover urine with sealing fluid 50, thereby prevent that stink from distributing.In other words, can not cause the stink burden by its weight ratio urine or the light sealing fluid of water as extraordinary oily 50 urine of having guaranteed to be deposited in the odour seal portion 44.

Perhaps, can not use sealing fluid 50 ground to use the odour seal portion 44 of a corresponding formation, wherein exist and being connected an of exhaust device.Because carry out before pump drainage goes out to urinate the specific impulse elution behind last intact lavatory, so only need low amounts of water when flushing, these water must be used for refilling the bent portion of odour seal portion 44.

By comparison, the blocking that the closure 42 of Fig. 5 has a liftable closure member 52 as has the mushroom geometry, it can axially move in an inserts 54, and this inserts is installed in the opening 26 in WC pans 10 propareas 12.The inserts 54 that is also referred to as receiving member is that be attached thereto and be used to hold an operation blocking 52 or the bottom of the operating mechanism 56 of its lifting is formed by a top that holds blocking 52 and one.According to Fig. 1, operating mechanism 56 links to each other with an activation members 60 by a bar 58, and this activation members is arranged on the edge of WC pans 10 and can operates by the cushion 62 at covering WC pans 10 edges.Can use mechanical type, pneumatic type or electrodynamic mechanical type standard package so that operation closure member 42, and when cushion 62 does not bear weight, resemble by the people cause operate closure member.In this case, closure member 42 is reduced and also seal opening 26 thus.

In order to make bar 58 stretch to toilet lid or toilet seat pad 62, in the petiolarea of WC pans 10, exactly around the horizontal-extending zone at WC pans edge 61 in a breach 57 is set.

Closure member or mushroom-shaped part 52 have an outer part 62 with the evagination at belt edge 64, and wherein diameter is equal to or greater than the diameter of opening 26.Especially city, the size at the edge 64 that goes in ring is so to set, promptly it is on the adjacent region that is pressed in inserts 54 or WC pans 10 bottom surfaces 20 on the lateral surface.Thus one, guaranteed to seal reliably and effectively opening 26 sealings, thereby extraneous material can not enter outlet opening 40 through opening 26.Simultaneously, the geometry of closure is so to be matched with bottom surface 20, and promptly liquid can not be deposited on the bottom surface.

In addition, the mushroom-shaped part 52 of closure 42 has the

hole

66,68 of radially extending, and their transition are a cavity such as a blind hole of extending towards opening 26, so that can discharge working fluid as urine by

hole

66,68.

Opening 26 also can seal by a mesh plate annex and the orifice plate that can rotate to it.By rotation hole half, can open or close mesh plate annex.

From Fig. 7,8, see another form of implementation of closure member 72.Here, the mushroom-shaped object 74 at lobed external surface 76 and belt edge 78 extends in the opening 26, and described edge is close on the bottom surface 20 of WC pans 10 (left side of Fig. 8) or is spaced from, so that allow liquid flow out.In this case, closure member 72 so extends, and promptly its cylindrical part 80 is arranged in opening 26 or transition is the outlet opening 40 of opening.Operating mechanism work of these cylindrical part 80 usefulness.

Between opening 26 and closure member 74 or cylindrical part 80, an inserts 82 that produces sealing function is set, it is as linking to each other with the part 86 that contracts in of the WC pans bottom surface of opening 26 by lute in.

As described in above repeat specification, urine can be equipped with an odour seal inserts 44 or closure member 42,72 through the opening 26 of its outflow, wherein also can adopt its combining structure.

Have the proparea 12 that being called as urine district and become the course of work of WC pans of the present invention of back zone 14 in stool district as follows.When weight such as people were sitting on the cushion 62, activation members 60 was opened opening 26 by lifting closure member 28.Therefore, urine arrives outlet opening 40 by opening 26.Itself also arrives back zone 14 solid and stool.In case remove cushion 62 pressures, then closure member 28 reduced and thereby close opening 26 by activation members 60.This closing motion for example can be mechanically, carry out by gravity, spring force or by pneumatic mode or other suitable mode.If opening 26 is closed, then can begin flushing, so that wash the inside of whole WC pans 10.In this case, flushing liquor also washes the district of urinating in other words, proparea 12.But, owing to opening 26 is closed, so liquid that can not arrives the outlet opening 40 of water conservancy diversion urine.Owing to can only when opening 26 sealings, carry out retinue system as described above, so can't carry out the mixing of flushing water and urine.Simultaneously, distinguish 12 bottom surfaces 20, guaranteed the liquid that can not accumulation by the geometry of closure member 28 and the smooth urine that carries out the transition to thereof.

Flushing actuating mechanism itself can be arranged on the back of cushion 62, thereby can only could start when the lid 88 that stretches out from cushion 62 covers WC pans 10.

By being linked to each other with the float valve of a flushing cisterns, lid 88 provides another kind of feasible program, and thus one, behind cover lid 88, the startup of washing automatically.

If proparea 12 openings 26 can't be closed by a liftable closure member 42,72, but it has only an odour seal inserts 44, then the flushing of WC pans 10 is so carried out, and promptly can only wash the district of defecating in other words, back zone continuously.And the proparea can only be accepted the water flushing termly.If odour seal portion does not have sealing fluid as the embodiment of Fig. 6, then when opening 26 pump drainages, taken away a spot of water.But compare with the discharging quantity of water of known toilet, this is negligible.
