The WC consists of an elongated receptacle (10) similar in ratio of length to width to an eastern squatting-type WC, with shrouds (11 ) at each end to contain urine spray and footrests on each side, at a slightly lower level than the receptacle, but at such a height above the floor that mounting the footrests is not uncomfortably precarious. The volume below the receptacle and footrests is used for a cistern, fed from a normal pressurised water supply, so that the flush water source is near the siphon jet entrance at the front part of the S-bend. A hinged seat, of suitable thickness / height so that when folded down and resting on the receptacle, forms a suitably high ring-shaped sitting surface.
Description
Technical field
The present invention relates to flush toilet (WC), just known lavatory pan.
Background technology
Above the flush toilet requirement user of modern western is sitting in when in use.Yet, in a lot of other places, Asian countries for example, at defecation or couchant when urinating be general custom.Studies show that during draining bodily waste, the crouching appearance is useful to health.Yet there is the people of disease at knee or back, and perhaps for example old people can not adopt the crouching appearance.For these people, they are forced to use the west flush toilet of sitting posture.Therefore, perfectly flush toilet is the flush toilet that can satisfy sitting posture and crouching appearance.
The U.S. 4,012, No. 797 patent disclosures a similar invention.Yet it is configured to a big platform, and with the part comparison of flush toilet, it more similarly is the part in bathroom.Therefore, compare with the flush toilet in west, its installation will be very difficult.Identical Asia crouching formula flush toilet (except Thailand's design of the pedestal formula that raises), its ground that also needs to imbed the floor or build up a rising holds the degree of depth of water closet pan.In addition, although the enough cisterns of doing of volume energy below the use lavatory pan do not have such claim.In common flush toilet, water be retained in S shape bend pipe than lower part, form water seal, stop stink to enter in the bathroom from sewer pipe.Yet in described United States Patent (USP), the invention plan is installed on the vehicle (aircraft, train etc.), and does not describe for S shape bend pipe with respect to user's water level.
In the flush toilet of sitting posture or crouching formula, the water that splashes out than lower part in the defecation process from water closet pan is very disagreeable.A kind of way that may reduce the water that splashes out is by making water level be positioned at level suitable under user's anus, usually can be too not low.This method by with the overflow weir partial design of S shape bend pipe a high level.Yet, wash away such lavatory pan, have to use a large amount of water fully also promptly to be full of S shape bend pipe, in order to form siphonage in the S bend pipe, siphonage is used for the refuse sucking-off in the water closet pan.In recent years, by in cistern, using bigger outlet valve or using the flushing system of pressurizeing, preserve a large amount of water that water makes that the designer has reduced needs to form before siphonage with pressure.The work of preserving water contradiction with needs is to make S shape bend pipe have the risk that major diameter reduces obstruction: large diameter S shape bend pipe needs more water to form siphonage.
The logic analysis of environment will draw the conclusion that the setting of washing away the water source should be close to the siphon spout of S shape bend pipe front, and has outlet valve between water source and spout.Eliminated the path that circles round that flush water need be passed through before by the siphon spout like this.Yet, sealed by toilet bowl portion at the edge thereon in the space in the place ahead of S shape bend pipe.Therefore, it can not be in high potential energy head storage flush water.This just draws the conclusion that needs the pressurization cistern, and described pressurization cistern obtains its pressure from the quiet pressure of supply water of watering.Typical quiet pressure of supply water is at least 1.3 crust, and it is converted to 13 meters potential energy heads, and any high-order gravity cistern of installing that numeric ratio can provide is much higher.Therefore, 1) be close to the outlet valve, 2 of siphon spout) the immediate water source of spout and 3) cause the combination of high pressure at the water source of the quickest formation siphonage to reduce the water that uses in the bath.
In other water closet pans, the another kind of method of eliminating the water that splashes out is that flush toilet is designed, so that ight soil is not on the water, but in the dried substantially part of toilet bowl.Occurred two shortcomings in this design: 1) stink of ight soil can not be isolated 2 by ight soil being immersed in the water) ight soil can stay stain in water closet pan, and these stains can successfully not removed by bath.On the contrary, if for the purpose of medical diagnosis with stool examination or collection, this feature is useful so.
Current also as can be known (from the Indian subcontinent) is those flush toilet that look like common west sitting type water closet, and the foot rest with wing extends out from every lateral edges.The height of foot rest is approximately sitting height.Therefore pedaling the described foot rest of stepping on is a uncomfortable and dangerous action.On the contrary, the foot rest of the pedestal formula crouching formula flush toilet (from Thailand) of rising is at lower height, and therefore pedals easily and step on.Yet such flush toilet can not use with sitting posture, because the height of bedpan is too low.In these two types, pin any moves can have and slips and drop into the floor or fall the into danger of lavatory pan from foot rest when adopting the crouching appearance.Another is conventional Asia flush toilet, and its pin is placed on the floor.This neither a good idea, when a people walks in the inside, lavatory, when particularly light is bad, is will emit to slip and fall into danger in the bedpan.
Summary of the invention
Because these Background Cause propose the present invention.
Goal of the invention
The purpose of this invention is to provide a kind of flush toilet, the deficiency that this flush toilet can overcome existing sitting posture, crouching formula and sit crouching convolution flush toilet.Therefore the present invention should be able to:
1, can adopt sitting posture or crouching appearance to use;
2, when when the crouching appearance is used, in the face of using at the two ends of flush toilet;
3, (as top the 2nd inference) part (in order to observe easily and/or the water that splashes is maybe avoided in the collection of stool sample when the diarrhoea time) of promptly allowing ight soil to fall into the inner substantially dry of bedpan also allows ight soil to fall into the water (can close the stink of ight soil apace) of the wet part preservation of bedpan;
4, all has the splash that shade is used for covering urine at every end;
5, have the foot rest of plate level (reducing to slip into the danger of bedpan when walking in the lavatory) above Ground, foot rest will have rational height (so that crouching appearance flush toilet pedal to step on be safe and comfortable);
6, has the edge of the rising that is different from described foot rest and bedpan to reduce the danger that slips into bedpan further;
7, when adopting sitting posture or crouching appearance, have the water surface that not too is lower than anus, thus water that reduces to splash even elimination;
8, the convenient installation need not punch or build up the floor of a lifting to hold flush toilet on the floor in lavatory;
9, the front of S shape bend pipe has the volume that holds cistern and holds flush water below bedpan, thereby water does not need by long and path that circle round by the siphon spout and enter into S shape bend pipe;
10, utilize the static pressure at water source to overcome the disappearance of the potential energy head of the cistern position of describing in the 9th;
11,, and need the water of relatively small amount to be used to wash away because the 9th and 10 combination.

The specific embodiment
With reference to figure 1, flush toilet of the present invention is made of the container 10 of lengthening, and its aspect ratio to the crouching formula flush toilet in east is similar.In addition, have shade 11 and 12, be used to cover splashing of urine at every end of container 10.Two ends be equipped with shade mean flush toilet can be couchant in the face of using at two ends.Along every side of container 10, than lateral edges 13 lower a little be foot rest 14.Described foot rest is made the shape of two footprints, in the face of rightabout heel and the setting of heel ground, meets ergonomics like this and can indicate the user to use according to its wish.The height of described foot rest so is provided with, and makes when the user squats in the above, and the lateral edges 13 of container 10 is enough high to stop pin to slip in the container 10.One in the foot rest 14 is shown as the part excision, thereby exposes cistern 15.For can near cistern 15 be used for installing, fixing and other similar purposes, in the present embodiment, foot rest 14 is designed to the separate unit that separates with the central location 9 that comprises container 10.In finishing the installation process of flush toilet, central location 9 for good and all is installed on the floor in bathroom basically, and its U-shaped pipeline is suitably sealed.Then, cistern 15 is mounted or adjusts with the relevant frame for movement of bath.At last, two foot rests are mounted in the mode that can remove, for using in the future.Yet, can be understood that, use additive method to provide also within the scope of the invention near other embodiment of cistern 15.
With reference to figure 2, container 10 than lower part, be S shape bend pipe 16 in the rear end, therefore it remains full of water after bath, form the stink that sewer is sealed in water seal.The height of the overflow weir 17 of S shape bend pipe makes the water surface 18 can not be lower than very much user's anus after bath, when the user squats on lavatory pan.So just reduced the water that splashes in the defecation process.Fig. 2 also illustrates the user and adopts the front end of preferred crouching appearance in the face of flush toilet.This posture for the crouching in Southeast Asia just the user than being familiar with.Obviously, ight soil can fall into the water, and water will promptly be sealed the stink of ight soil.
Still with reference to figure 2, the cistern 15 that is used to store flush water be positioned at foot rest 14 and container 10 below.By outlet valve 22 controls, this outlet valve next-door neighbour is siphon spout inlet 20 then, has therefore improved the speed that forms siphonage, thereby preserves water from the current of the flush water of cistern 15.Significantly, the setting at so low locational cistern 15 means that the potential energy head of the water in the cistern will be not enough to wash away.In order to overcome this point, cistern 15 must replenish from the water source of pressurization, and this is generally can obtain for any Modern Family substantially.The water source of pressurization is full of cistern 15 and suppresses air at an upper portion thereof, and this point just makes the pressure in the cistern equal the static pressure at water source.In the process of bath, outlet valve 22 is opened, and the water of the pressurization in the cistern 15 is released and promptly enter into S shape bend pipe 16 by siphon spout inlet 20, therefore promptly forms siphonage.The volume of the water that the process of each bath discharges is controlled by the suitable design of outlet valve.Cistern shown in the present embodiment is as unit independently, can be understood that, the replacement design that cistern and flush toilet are integrated also is within the scope of the invention.
As shown in Figure 2 be two passages 23 and 24, be used for water is guided to respectively the leading edge 25 and the back edge 26 of container 10.It is possible providing the several method with controlled water flow by these passages 23 and 24.For example can separately supply water from cistern 15 to them.In the process of bath, can at first be discharged the inside of cleaning container 10 by their water, open the of short duration delay that forms siphonage at outlet valve 22 after, then after siphonage is broken, they can be held one short period, in order to refill S shape bend pipe.Another possibility is not open outlet valve 22 to realize the bath of water saving part by only opening the water in water flushing channel 23 and 24.Also having another may be that described passage is supplied with water by identical outlet valve 22.
Fig. 3 shows the selection of using (operating) water nozzle 27 on water flushing channel 23 outlets.Later again with reference to figure 2, this selects also can use in the outlet of water flushing channel 24.The aquaporin in leading edge 25, lateral edges 23 and back edge 26 and the needs of water out sky have been eliminated in this selection, and the needs of aquaporin and water out sky require to make the position that extra processing during the flush toilet and foul are piled up.Described nozzle is made by the material that can accurately make in the manufacture process, injection-moulded plastic for example, thus water spray can accurately form with the total inner surface of covering container 10 and can not miss the current form that any zone or formation are wanted.The current that for example can form relatively big diameters are 25 and 13 following effluent along the edge, thereby enough water can arrive the middle body of container 10.Can form the thin relatively film of current, flow through other parts of described container.Can also form bigger current, flow waterpower to promote the ight soil (if there is) in S shape bend pipe along the lowermost portion of container 10.In addition, shown nozzle 27 can be removed and be used for carefully cleaning.Can also use can be floating the described nozzle of material, if on one side its call in flush toilet once in a while, it can be found easily.
Fig. 4 shows the user and adopts alternative crouching appearance in the face of the flush toilet rear end.This posture is familiar for the Asiatic water closet pan user in Southeast Asia.Finding out clearly that from this accompanying drawing ight soil will drop on the part of doing basically 28 of container 10, though this using method does not seal up the stink of ight soil, is useful when needing observation and collecting ight soil.In addition, when diarrhoea time this using method allow liquid manure drop on the very approaching surface recessed and that inclination is arranged of anus on, therefore will reduce or even eliminate the water that splashes.Also can promote to reduce the water that splashes by the current of opening in the passage 23, the film of the water that flows can be taken away the ight soil that falls fast.
Fig. 5 shows the toilet seat 29 at lower position.Because the existence of shade 11 and 12, the height of ring are usually on the height of described shade and therefore at a comfortable sitting posture height.Ring can have the vertical web member 30 of suitable quantity in every side, and it is engaged in the top of lateral edges 13, supports the user's that sits down weight.
Describe and explanation only be preferred embodiment of the present invention, be understandable that, much change, revise and distortion can be applied on the lavatory pan of the present invention, and do not depart from the scope of the present invention and spirit.
