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

The present invention relates to a kind of bedpan, this bedpan has the front area of a discharge urine, and this front area has first an interior opening of pit that leads to first outlet and especially be stretched over this front area; With the second area with the rear portion of leading to second outlet that holds ight soil, separately to discharge urine and ight soil, wherein this front area has the degree of depth littler than this Background Region.

Usually, urine and ight soil are to discharge from bedpan or urinal together.Therefore have such shortcoming, the sanitary wastewater composition that promptly can utilize again in some cases is with the composition that can not utilize or mix passage of 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 through the outlet from holding urine portion of this front portion.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 1,27 7,232 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.

The objective of the invention is to improve in this wise the bedpan of the described type of beginning, make and to separate urine and ight soil reliably with simple measure, thereby they are separately discharged based on the problems referred to above.Should reduce simultaneously the consumption of the water that is used for washing front area, wherein these water can be used for cleaning Background Region simultaneously in some cases, only promptly hold the ight soil part.Here guarantee also that liquid does not arrive the outlet of discharging urine when the flushing front area.

So address the above problem according to the present invention, promptly the front area and first opening from bedpan feeds in the cavity, this cavity is transformed on the one hand can be by closure elements switching and first outlet of opening, by second opening and such being communicated with of the second area of bedpan, make that liquid can flow by second opening by closure elements first outlet time on the other hand.Wherein this first opening is made up of many single holes especially, 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 one 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.Can be for a little annular seal elements from the perisporium of this housing, 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, imagination especially wherein, and only when the action of gravity of the seat board that is subjected to covering bowl rim, valve disc just can lift from valve seat.Therefore when the action of gravity that is provided with seat board, export with respect to first and close with the cavity of open communication, when being arranged, action of gravity then is communicated with first outlet, wherein 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.It is contemplated that in addition, only when bedpan cover is closed seat board, could operate flushometer, make and to guarantee, cut off by closure elements from the connection between first outlet of the opening of the pit in urine zone.Therefore liquid can only and be distributed in cavity flow below them to second area by the single in other words hole of opening, and just the flushing of the cavity under opening and the opening is carried out in the ight soil zone of bedpan thus simultaneously.

In order to ensure, the urine that flows in the bedpan first area does not arrive in the second area, imagines in addition, and the first area has the bottom surface that comprises pit, this bottom surface is about 5 ° with respect to the angle [alpha] slant dilation, particularly α of horizontal level from 2 °≤α≤10 °.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 second area.In order to prevent this point, a kind of improvement structure of the present invention is imagined in addition, and the first area carries out the transition to second area by an edge, and this edge exceeds height a h, particularly h≤20mm with respect to pit.

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 first area on request, and can not arrive in the ight soil zone.All the time guaranteed that at this zone that contacts with urine is cleaned clean when the flushing bedpan, obtained cleaning because between flush period, discharge the opening of urine.Simultaneously between first and second zones of bedpan, do not need dividing plate in accordance with this principle.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.

Obtain in feature one feature itself that obtains during other details, advantage and feature of the present invention not only required by claim, accessory rights and/or their combination, also by obtaining in the following explanation to the preferred embodiment that from accompanying drawing, obtains.

Accompanying drawing is depicted as:

The vertical profile of Fig. 1 one cellular-type bedpan is looked,

Fig. 2 by the cellular-type bedpan of Fig. 1 together with the partial view of the closure elements that is adopted when the fastening position,

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

A bedpan 10 that constitutes by 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 and is discharged from, and is to discharge by the deodorization close mouth 16 of making siphon arrangement, and this close mouth is transformed into an outlet.

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 rear portion or second area 14, distribution one is by the opening 32 that

single hole

22,24,26,28,30 constitutes in this pit, and the urines that fall in the front area 12 are discharged by this opening.Opening 32 passes the diapire 34 of bedpan 10, and leads to a cavity 36, and cavity 36 penetrates the breach 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 rear portion or the second area 14 of bedpan 10.This external 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 a union 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 breach 40 directions, make liquid that can not accumulate between housing 46 and the installing hole 50.Arrive rear portion that this regional liquid flows into bedpans 10 by breach 40 in other words in the second area, just in the ight soil zone but make.

Closure elements 42 comprises the valve body 54 that can axially adjust in housing 46, and has a valve disc 56, and this valve disc is fitted on the annular seamed edge 58 of housing hermetically, perhaps can leave this seamed edge certain distance.Valve disc 56 is fitted on the seamed edge 58 hermetically in Fig. 2, and this seamed edge plays valve seat.Therefore cavity 36 is closed with respect to the inside of housing 46.If use bedpan, bedpan 10 1 unillustrated seat boards are 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 opening 62 that is surrounded by seamed edge 58 of housing 46.Therefore can discharge urine in first or the front area 12 that arrives bedpans 10 by the

single hole

22,24,26,28,30 that opening 32 constitutes this opening in other words, so that flow to outlet 48 places by enclosure interior 44, this outlet can be connected on the negative pressure source in some cases.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 shell nozzle 62 directions motions so.If start one towards clear process, so not only wash front area 12, and clean opening 32 and be distributed in closure elements 42 and opening 32 between cavity 36, the liquid that arrives through opening 32 from this cavity flows into second or Background Region of bedpans by breach 40.Therefore whole subregions that may contact with urine of bedpan 10 are all cleaned fully.But guaranteed that simultaneously liquid can not accumulate in the front area 12, particularly in the cavity 36 that exists between pit or the opening 32 in closure elements 42 and pit 20.The liquid that comes from the urine zone then 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 16.

But for a large amount of at liquid or high velocity stream is fashionable still guarantees: urine is stayed and is held in the urine portion 12, and pit 20 can carry out the transition to ight soil zone 16 by a raised portion 64 of bedpan 10.Here the summit of part 64 or projection can have difference in height h between 5 to 20mm with respect to the pit 20 in opening 32 zone.However, still what deserves to be mentioned is, in pit 20 zones, can not gather liquid, because liquid holds ight soil part 16 through the 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 fringe region 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.By a medium pore 26 with form around four

single holes

22,24,26,28,30 of this medium pore equably, the single hole of varying number can certainly be set at described embodiment split shed 32.

Workflow by the bedpan with the first area 12 that is called the front portion that holds urine portion and the second area 14 that works the rear portion that holds the ight soil partial action of the present invention is as follows.If effect one gravity on the seat board that is positioned on the bedpan 10, for example the people operates closure elements 42 by a releasing device so, even only an obturator 54 moves, so that open the shell nozzle 62 that leads to valve chest 46 inside 44.Therefore urine can arrive through the inside 44 of cavitys 36 and housing 46 by the opening 32 is made up of

single hole

22,24,26,28,30 and export 48, and flows out under action of gravity and/or by negative pressure.Solid and ight soil itself arrives Background Region 16.In case the suffered active force of seat board alleviates, just guarantee by a unillustrated releasing device, make obturator 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 opening 32 thus.If therefore start flushing process, flushing liquid can flow into ight soil zone 14 from front area 12.Carry out the cleaning of opening 32 and cavity 36 simultaneously,, arrive ight soil zone 14 by breach 40 again because flushing liquid can flow into cavity 36 through opening 32.Here valve chest 46 is fixed in the cylindrical installing hole 50 of bedpan in this wise, makes not form the dead band that may gather liquid.But 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 pass through breach 40 inflow ight soil zones 14.

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.
