Abstract

The invention relates to a toilet bowl (10) comprising separate parts (12, 16) respectively provided for receiving urine and feces. The aim of the invention is to effect a reliable separation between urine and feces with the use of structurally simple measures. To this end, the invention provides that an opening (32), which starts from the urine-receiving part, leads into a space (36) that, on the one hand, verges into a urine discharge (48) and, on the other hand, is connected to the feces-receiving part.

Description

Bedpan

Technical field

The present invention relates to a kind of bedpan, this bedpan has: the front area of discharging urine, first opening of the diapire of this front area of this front area by passing this bedpan changes a cavity over to, itself draws first outlet that can open and close and open by a closure elements from this cavity; Hold ight soil and Background Region that lead to second outlet, separately to discharge urine and ight soil, this front area has the degree of depth littler than this Background Region.

Background technology

Usually, urine and ight soil are to discharge from bedpan or urinal together.Therefore have such shortcoming, promptly the lavatory that can utilize again in some cases the sewage composition with the composition that can not utilize or passage of mixing input.

For fear of this shortcoming, known, bedpan or urinal are divided into two zones by dividing plate, thereby spatially separate, and wherein determine a Background Region and a front area that is used for urine that is used for ight soil, make and can separately discharge.For example by FR 2,674, the known corresponding cellular-type bedpan of 881 A1 or WO92/190824.

For corresponding cellular-type bedpan, its shortcoming is dividing plate, and promptly this dividing plate not only needs frequent cleaning, and also has problems aspect manufacturing process.Because the dividing plate between proparea and the back zone is to the vertical stretching of bedpan opening direction, the distance between the people of dividing plate and use bedpan is smaller, therefore also needs the process of a custom.

Because divider upright stretches, limit front area, the bedpan area that also promptly holds urine portion is bigger, therefore needs a large amount of flushing liquids, and these flushing liquids are discharged from holding the outlet that urine portion draws through these front portions.For fear of such situation, there is such possibility, promptly dividing plate is provided with a breach (FR 2,674,881 A1), and this breach is distributed in the pit top, and opening is from pit.More expense not only takes place when manufacturing is used for the mould of corresponding bedpan thus, and leaves remaining liquid in pit all the time.

Learn a kind of bedpan by the US 1,277,232 that is derived from 1918, wherein hold the ight soil part and hold urine portion and can be separated from each other.Here hold urine portion and directly be transformed into a discharge pipe.Holding urine portion and holding and extend a dividing plate along this pipe stretching, extension between the ight soil part.

Obtain the cellular-type bedpan of the described type of a kind of switch by EP 0 323 901 A1.The front area that gathers urine has one first outlet, and this outlet is drawn from a pit of excrement basin.Urine flows to a measurement mechanism through this first outlet, to determine its constituent, holds in the Background Region of ight soil so that flow into then.

Summary of the invention

The objective of the invention is to improve in this wise the bedpan of the described type of beginning, make and not only can separate urine and ight soil reliably, and can use towards clear water and wash this front portion and this Background Region simultaneously based on the problems referred to above.Guarantee also that simultaneously urine or liquid that can not accumulate in from the cavity in urine zone.

According to the present invention, in order to address the above problem, a kind of bedpan is provided, it has: the front area of discharging urine, first opening of the diapire of this front area of this front area by passing this bedpan changes a cavity over to, itself draws first outlet that can close and open by closure elements from this cavity; Hold ight soil and Background Region that lead to second outlet, separately to discharge urine and ight soil, described front area has the degree of depth littler than described Background Region, it is characterized by: described cavity is communicated with the described Background Region of described bedpan by one second opening, and when this first outlet was closed by described closure elements, liquid can flow into described Background Region by described second opening.Here, first opening particularly is made up of many single holes, and the diameter in each single hole is selected like this, makes solid not discharge by these holes.

Five independent holes particularly are set, and are a centre bore and four independent holes that center on this centre bore equably.

This closure elements has a valve body that has valve disc that can move in a housing, this valve body can be fitted in from the valve seat of this housing or with a certain distance from this valve seat, wherein this housing this in the bottom surface one gusset decide cavity, this first opening feeds in this cavity.Here the housing that preferably has cylindrical geometries can be fixed in the correspondingly configured installing hole of bedpan hermetically with respect to bedpan.For this reason, an annular seal element can be from this housing perisporium, and this potted component can support hermetically with respect to the installing hole of bedpan.Here guarantee that liquid that can not accumulates in the respective regions, these liquid may cause foul smell in some cases.This first outlet will be therewith irrespectively from housing.

This valve body can pass through an executive component adjustment, wherein special provision, and only when the seat board that covers bowl rim bore gravity, valve disc just can lift from valve seat.Therefore, when seat board does not bear gravity, close with relative first outlet of cavity of open communication, when being arranged, action of gravity then is communicated with first outlet, this executive component can be connected with a releasing device machinery, pneumatic or electromagnetism together with valve body, and releasing device itself can be handled by seat board and/or flushometer.Only it is also conceivable that and when bedpan cover is closed seat board, could operate flushometer, guarantee thus, cut off by closure elements from first opening of the pit in urine zone and the connection between first outlet.Therefore, liquid can only and be distributed in cavity flow below them to Background Region by the single in other words hole of first opening, the ight soil zone of bedpan just, and the result carries out the flushing of the cavity under first opening and first opening simultaneously.

In order to ensure, the urine that flows in the bedpan front area does not arrive in the Background Region, also imagine, front area has the bottom surface that comprises pit, the described bottom surface that comprises described pit is about 5 ° with respect to horizontal level with the angle [alpha] slant dilation, particularly α of 2 °≤α≤10 ° at it at least in the Background Region of described bedpan zone far away.Make urine enough flow to pit thus slowly, make to get rid of or get rid of fully from the overflowing of pit, thereby prevent to flow in the Background Region.In addition, in order to prevent this point, a kind of improvement embodiment of the present invention stipulates that to Background Region, this edge exceeds height a h, particularly h≤20mm with respect to pit to front area by an edge transition.

By a kind of cellular-type bedpan is provided by principle of the present invention, guaranteed with it, discharge the urine that falls in the front area on request, and can not arrive in the ight soil zone.All the time guaranteed that at this front area that contacts with urine is cleaned clean when the flushing bedpan, obtained cleaning because between flush period, discharge first opening of urine.Simultaneously, in accordance with this principle, between the front area of bedpan and Background Region, do not need dividing plate.But even now has guaranteed that still urine is discharged through first opening fully or almost completely.

In other words, having got rid of needs accurately and does not have the problem of using above-mentioned known cellular-type bedpan discomposingly, and flushing water may arrive in the urine outlet.

What deserves to be mentioned is by principle of the present invention and can realize reliable separation between ight soil and the urine.Such possibility is provided thus, the urine that is high concentration is for example not only as fertilizer, and for example can extract medicine or can remove contaminant (radioactive substance, X-ray radiography solvent) by the urine of independent discharge, that is to say particularly can not the conventional material that decomposes.The urine of discharging also can directly be chemically examined separately.

Also have such possibility without a doubt, that is, will import an intermediate receptacle by the urine of holding the urine portion discharge, so that for example follow the tracks of radioactive decay time, Xiang Guan measure is for the patient diagnosis particular importance therewith.Here be from such understanding, promptly radioactive substance is most of discharges by urine rather than by ight soil.

Fig. 3 is corresponding to the view of the closure elements of opening having of Fig. 2.

The specific embodiment

The bedpan 10 that constitutes according to the present invention has been represented on pure principle ground in Fig. 1, and it plays the cellular-type bedpan, that is to say that urine and ight soil are separated from each other discharge therein.Here corresponding cellular-type bedpan not only can be with in the family, and particularly can be used in the field of medicaments, and the place that need chemically examine separately of urine for example just is for example in order to determine the decay time of foreign matter, medical components or radioactive substance.

Bedpan 10 or its urinal have a front area 12 and a Background Region 14.Wherein the front area 12 of bedpan 10 is used for compiling urine, therefore can be called and hold urine portion.Ight soil collects in the Background Region 14 and is discharged from, and is to discharge by the deodorization close mouth of making siphon arrangement, and this close mouth is transformed into one second outlet 16.

Front area 12 with degree of depth littler than Background Region 14 comprises a bottom surface 18, this bottom surface is transformed into a pit 20 in the fringe region that leads to Background Region 14, first opening 32 that is distributing in this pit and be made of

single hole

22,24,26,28,30, the urine that falls in the front area 12 is discharged by first opening.First opening 32 passes the diapire 34 of bedpan 10 and leads to a cavity 36, and cavity 36 penetrates second opening 40 that bedpan 10 is distributed in the boundary's wall 38 that holds urine portion one side by one and is communicated with the Background Region 14 of bedpan 10.In addition, cavity 36 is communicated with the inner chamber 44 of cylindrical housings 46 by the difference of closure elements 42 according to its position, stretches out first outlet 48 that is used for discharging urine from this inner chamber.Housing 46 is fixed in the cylindrical installing hole 50 of bedpan 10 by a lip ring 52.

Housing 46 fixing seals 52 are extended on a circumference along cavity 36 and second opening, 40 directions, make liquid that can not accumulate between housing 46 and the installing hole 50.Arrive in the Background Region of this regional liquid by second opening, 40 inflow bedpans 10, just in the ight soil zone but make.

Closure elements 42 comprises the valve body 54 that can axially adjust and has a valve disc 56 in housing 46, this valve disc is fitted on the annular seamed edge 58 of housing 46 hermetically, perhaps can leave this seamed edge certain distance.In Fig. 2, valve disc 56 is fitted on the seamed edge 58 hermetically, and this seamed edge plays valve seat.Therefore, cavity 36 is closed with respect to the inside of housing 46.If use bedpan 10, the unillustrated seat board of bedpan 10 is subjected to action of gravity so, make valve body 54 for example by means of a wire (Bowden cable) in housing 46 along cylindrical slideway 60 from seamed edge 58 or valve seat on axially retract, make valve disc 56 open the inlet 62 that is surrounded by seamed edge 58 of housing 46.Therefore, can discharge urine in the front area 12 that arrives bedpans 10 by the

single hole

22,24,26,28,30 that first opening 32 constitutes first opening in other words, so that flow to first outlet, 48 places by housing inner chamber 44, in some cases, this first outlet can be connected on the negative pressure source.If the suffered active force of bedpan seat board alleviates, just valve body 54 makes valve disc 56 be fitted in valve seat hermetically in other words on the seamed edge 58 of the housing 46 of closure elements 42 to the motion of inlet 62 directions of housing so.If startup flushing process, so not only wash front area 12, and clean first opening 32 and be distributed in closure elements 42 and first opening 32 between cavity 36, the liquid that arrives through first opening 32 from this cavity flows into the Background Region 14 of bedpans 10 by second opening 40.Therefore, whole subregions that may contact with urine of bedpan 10 are all fully cleaned.But guaranteed that simultaneously liquid can not accumulate in the front area 12, particularly in the cavity 36 that exists between pit or first opening 32 in closure elements 42 and pit 20.Then, the liquid that comes from the urine zone also cleans and holds the ight soil part.

If preferably adjust valve body 54, so equally also can consider other executive components, and not deviate from principle of the present invention by means of flexible axle.

Shown in sectional view, wherein be distributed with the bottom surface 18 of pit 20 in holding the zone of urine portion and should have surface to pit 20 slight inclination, particularly bottom surface 18 has an inclination alpha with respect to horizontal level, this inclination angle is between 2 ° to 10 °, particularly in the scope about 5 °.Make urine enough 18 flow to pit 20 along the bottom surface thus slowly, make and get rid of basically, just hold overflowing into of ight soil part to Background Region 14.

But, guarantee still that for or high velocity stream a large amount of at liquid is fashionable urine stays in the front area 12, the edge 64 of the rising that pit 20 can be by bedpan 10 carries out the transition to the ight soil zone.Here, the summit of edge 64 or projection can have difference in height h between 5 to 20mm with respect to the pit 20 in first opening 32 zone.However, still what deserves to be mentioned is, in pit 20 zones, can not gather liquid, because liquid holds the ight soil part through first opening 32 and cavity 36 flow directions.

Single hole

22,24,26,28,30 has such diameter, and this diameter allows liquid to flow through on the one hand unobstructedly, but guarantees to block solid, for example paper on the other hand.Paper edge 64 through ight soil one side when flushing bedpan 10 floats.

The diameter in

single hole

22,24,26,28,30 should be between 3 to 7mm, in particular for 5mm.In described embodiment, first opening 32 is by a medium pore 26 and form around four

single holes

22,24,26,28,30 of this medium pore equably, and the single hole of varying number can certainly be set.

To have the workflow that is called front area 12 that holds urine portion and the bedpan that works the Background Region 14 that holds the ight soil partial action as follows by of the present invention.If effect one gravity on the seat board that is positioned on the bedpan 10, for example the people by a releasing device operation closure elements 42, that is, moves valve body 54 so, so that open the housing inlet 62 that leads to housing 46 inner chambers 44.Therefore, urine can be passed through first opening, 32 process cavitys 36 and housing 46 inner chambers 44 arrival, first outlets of being made up of

single hole

22,24,26,28,30 48 and flow out under action of gravity and/or by negative pressure.Solid and ight soil itself arrives Background Region 14.In case the suffered active force of seat board alleviates, just guarantee by a unillustrated releasing device, make valve body 54 particularly the effect by spring force move towards the direction of the ring edge that plays the valve seat effect 58 of housing 46.Cavity 36 below housing one side closure first opening 32 thus.Therefore, if start flushing process, it is Background Region 14 that flushing liquid can flow into the ight soil zone from front area 12.Simultaneously, carry out the cleaning of first opening 32 and cavity 36,, arrive the ight soil zone by second opening 40 again because flushing liquid can flow into cavity 36 through first opening 32.Here, housing 46 is fixed in the cylindrical installing hole 50 of bedpan in this wise, does not promptly form the dead band that may gather liquid.And the whole liquid that arrive in the annular chamber in the cavity 36 and that retained by valve chest 46 and installing hole 50 all flow into Background Regions 14 through second opening 40.

The releasing device of flushing itself can be arranged on the seat board back, only makes could to operate releasing device when the lid from seat board covers bedpan.

By covering and being connected of float-controlled valve of flushing tank providing another kind of possibility, when closing, lid automatically starts water-rinsing process thus.
