Description

Rimless toilet with flush water distribution apparatus

Technical field

The present invention relates to toilet, relate in particular to the toilet of no labial surface.

Background technology

In the prior art, the quite a long time can be used the toilet of various types.The example that has shown a traditional toilet among Fig. 1 by section.The toilet labial surface (Reference numeral B) that traditional toilet generally comprises bedpan or pond (Reference numeral A) and extends around the bedpan top.During flush toilet, water is imported to the rear portion of bedpan from inlet tube.Enter toilet water major part by in the vertical direction downwards and towards the bottom-boot of bedpan, at the place, bottom of bedpan, water enters soil pipe or U-bend (shown in the arrow among Fig. 1) along the rear wall of bedpan.Simultaneously, flow than the water inlet of the small scale labial surface around toilet, described labial surface is formed by inverted U-shaped usually, washes the inner surface of bedpan to allow the aperture of water by as shown in the figure to flow downward along the inner surface of bedpan.Water enters in the bedpan along channel flow and by these holes.

Although traditional toilet is very universal and advantage is arranged, there are a lot of significant disadvantage in the toilet that includes labial surface.For example, because the profile of traditional toilet labial surface, grow the place and provide collection region for refuse for microorganism and bacterium provide.The profile of described labial surface also can make be difficult to clean effectively labial surface around.In addition, be difficult to check the part of labial surface downside, this means that the some parts of toilet does not often clean for a long time or indefinitely.Microorganism and material below labial surface or this accumulation on every side be antihygienic, to be that public lavatory, hospital etc. are special worry for this.Referring to for example GB 2431937, the known in the prior art toilet with improvement labial surface is to attempt to solve some described problems.

Yet the design of prior art fails to provide a kind of toilet device that efficient and effective flushing action are provided that combines with toilet, thereby can not eliminate the possibility of microorganism and/or bacterium accumulation or breeding in labial surface or around labial surface basically.Therefore, need a kind of toilet that can overcome the toilet of described problem and have improved spatter property.The present invention is considering described problem at least in part and is considering under the situation of traditional toilet shortcoming and made.

Summary of the invention

According to first aspect, a kind of toilet is provided, comprise the bedpan and a pair of water inlet of no labial surface, described water inlet in use is arranged on the opposite direction of substantial horizontal inner surface guiding around bedpan, and all flow into the water in toilets basically.

According to the present invention, by described two water inlets only on opposite and substantially horizontal direction guiding receive all basically flushing waters in the toilet, that is, water is not as directly guiding the downward inflow bedpan from import in traditional toilet.In the prior art, shown in the arrow among Fig. 1, the whole basically water that receives in the bedpan is guided towards U-bend, to produce necessary flushing action.Flatly guide all water to make and on the opposite side of bedpan, produced the flushing water column, thereby described flushing water column cleans the inner surface of bedpan and produces essential flushing water column.Use makes the zone around can the bedpan of microorganism accumulation, bacterium and material reduce to minimum without any the toilet of kind labial surface, and the observability the best that makes bedpan inside is in addition checked easily and easily allowing.

The all basically water of guiding was not considered in the prior art on the opposite direction of level, directly guided a large amount of water to produce necessary flushing action because be traditionally downwards by the U-bend towards bedpan.Should be understood that term " all basically " is to be used to refer to nearly all water that enters toilet, but some water can be stayed in the toilet and/or evaporation etc.

Term " no labial surface " is a kind of bedpan that is used to refer to the surface that overhangs of the upper surface extension that does not center on labial surface in this article.By removing the surface that overhangs, improved the observability of bedpan inside greatly.In addition, improved the entering of bedpan in order to cleaning.

Water can be directed in the bedpan by water dispenser, and described water dispenser for example can protrude by the inwall from bedpan at the bedpan rear portion.Alternatively, water can lead in the bedpan from a pair of recess, and described recess is formed in the bedpan wall and in use arranges and is used for flatly guiding as mentioned above water.Import is formed into further removed the grow edge of microorganism and bacterium of perhaps relevant meeting in the recess on the nightstool wall with the water inlet that protrudes.

In order to make flushing and cleaning action maximum, can flushing water be imported in the bedpan in the upper edge of the bedpan of close no labial surface.The bedpan area maximum that water flows through flushing water is introduced at top at bedpan, and makes unwashed bedpan area minimum.

In two opposite water inlets each can by layout be used for water lead in the bedpan single mouthful formed.Alternatively, each mouthful can be formed by a plurality of hole, and each hole is arranged and is used for water is led in the bedpan.

Should be appreciated that term used herein " essentially horizontally " is the complete bottom horizontal flow sheet that is not limited to water, but approximate horizontal is mobile, so that in use, around the inner surface guiding water of bedpan, on the opposite side of bedpan, to meet and to collide.

In order advantageously to make water circulation around whole bedpan, bedpan can be furnished with the water guiding piece or the flange of a pair of circumferential extension, each guiding piece or flange have first end, and contiguous one of them flushing water import of described first end and in use arranging is used in the week guiding or transmit flushing water in the bedpan of the opposite direction of substantial horizontal.

In use, water flows out from each import, and is guided along the top of each water guiding piece and around bedpan.Each guiding piece has prevented that advantageously water from flowing by the mode in traditional toilet,, directly flows to U-bend downwards that is.In use, guiding piece also transmits water around the inner surface of bedpan from each import, so that water collides and produce " water column " on the opposite side of bedpan, described " water column " flows in the U-bend then.The configuration of guiding piece has advantageously provided the surface that can transmit water in the above.In addition because do not have overhang surface or labial surface, so guiding piece without any hidden parts, and can be easily and check cleannes easily.As mentioned above, advantageously, guiding surface is also convenient and be easy to cleaning, and is approaching because burnisher is easy to.

What recognize is to observe the inner surface of toilet in the prior art easily.Even in the list of references of mentioning in the above, set labial surface has hindered the inner surface of fast and easily checking bedpan.

From another point of view, a kind of toilet is provided, described toilet comprises the bedpan of no labial surface and is arranged to water is led to water dispenser in the bedpan, described bedpan also comprises the water guiding piece of two approximate horizontal, and they are arranged on the inner surface of described bedpan and in use receive water and transmit water along water guiding piece upper surface from each flushing water import.

In fact, described guiding piece is as the surface of transmitting water by means of the flow of the water that enters bedpan.Each guiding piece or flange can become the surface of protruding from the inner surface of bedpan by favorable terrain, that is, with the inner surface of bedpan be one.Therefore, can use traditional manufacturing technology to form guiding piece easily.

Each guiding piece/flange is by the near-end of close respective inlets and formed around the far-end of bedpan periphery a distance.Whole surface in order to ensure bedpan is cleaned, and flange can extend around the whole periphery of bedpan, so that converge mutually in the front portion of bedpan.

Guiding piece or flange can have any suitable profile or structure, comprise the surface of carrying and/or guide water when water when bedpan flows.For example, guiding piece can be the form on substantial horizontal surface, and water is carried on this horizontal surface and along it and flows.As discussed above, the current around bedpan are advantageously carried on this surface, and also allow in addition easily the inspection (for cleannes) to toilet, and allow easily to clean the inner surface of toilet.

The whole or a part of of each guiding piece/flange can tilt with respect to the inner surface of bedpan, for a long time water is carried on the flange when bedpan flows at water.Guiding piece can change, and for example along whole or a part of inclinations of guiding piece length, overflows from the guiding piece inward flange with the part of the water that allows to flow along each guiding piece, so that flow on the bedpan inwall below the guiding piece.In fact, a part of water around the inner guiding of bedpan is allowed to roughly being downward through the inner surface of bedpan from guiding piece on the vertical direction, so that wash the inner surface of bedpan.What recognize is, the component motion that the water that flows from guiding piece by this mode will have approximate horizontal when flowing at the edge from guiding piece therefore will be around bedpan circulation when water is mobile from guiding piece.Like this, when water centers on the bedpan surface and is downward through the bedpan surface, washed the inner surface of bedpan easily.This can be by the whole or part of flange being arranged to there is low-angle on the leaving water plane so that a part of water flows through the flange inner surface realizes.Flange can for example become the angle of 1 to 15 degree with horizontal plane.

Alternatively or additional, this can realize having first width near the respective inlets place and have the second less width at the far-end of flange by making each flange.Advantageously, guiding piece can be arranged to from near-end tapered to far-end, narrows down so that the bearing surface that water flows centers on the periphery of bedpan.The far-end of guiding piece can converge at relative with water dispenser basically some place on the bedpan periphery mutually, to guarantee transmitting water around the whole periphery of bedpan.

For the cleaning of optimizing bedpan with the flushing water of standard volume flushing action to toilet, guiding piece can have first end near each flushing water import, its guiding width more preferably between 50 millimeters to 60 millimeters, and most preferably is 58 millimeters between 40 millimeters to 65 millimeters.The width of the far-end of each guiding piece can be between 1 millimeter to 8 millimeters, more preferably between 2 millimeters to 5 millimeters, and most preferably is 3 millimeters.Verified, described most preferably value has been optimized the generation of flushing water column, has optimized the cleaning action of bedpan simultaneously.Also can be by the roughly symmetrical generation of optimizing water column in the inside that makes bedpan.

The size that depends on bedpan, taper also can be arranged to make guiding piece to stop at the place, a part of path of bedpan periphery, that is, guiding piece can narrowly gradually be reduced in the bedpan wall.What recognize is in this layout, to allow to flow in the bedpan along the water augmenting portion that each guiding piece flows.

Guiding piece can advantageously be arranged to guide two reciprocal current, so that on the position relative diagonally, collide with inlet device one-tenth, that is, and at the front shock of bedpan.Should be appreciated that the height of two current points of impingement (for the height of the liftoff plate of bedpan) depends on the ad hoc structure of guiding piece and the flow of water.Select guiding piece structure so that the water of enough ratios at the front shock of bedpan, and make by means of the momentum of water water by on the direction of roughly crossing bedpan backward towards the rear portion guiding of toilet." point of impingement " is actually and produces at two bursts of current places of meeting, and " point of impingement " produced the water turbulence district of crossing the bedpan bounce-back.

At the part place of each guiding piece near each flushing water import, as mentioned above, described import can be formed in the recess of bedpan inwall.It is formed with the upper surface relative with it that recess is actually the soffit that is limited by tapered guide spare, described upper surface plays the effect of lid, to prevent to spray from any water of each water inlet the top of bedpan when water leads on the guiding piece with maximum flow.Advantageously, this surface can narrowly gradually be reduced in the bedpan wall, so that the accessibility of bedpan inner surface and observability the best.

The inner surface of bedpan can also have other osculum, and described osculum is in use arranged and is used for allowing a spot of water to flow through two bedpan parts between the opposite water inlet.This whole surface of guaranteeing bedpan receives current, so that the flushing to whole bedpan surface to be provided.The flushing water of the only small scale that toilet receives need flow through this part of bedpan.For example, described two opposite imports can be configured to receive and surpass 90% the water (each receives 45%) in the toilet of receiving, and the remaining water yield flows to and is arranged in two opposite imports tops and is in therebetween flushing import.Described flushing import can be arranged in any suitable height place with respect to the bedpan upper surface, but preferred arrangements is at close upper surface place, so that the bedpan area maximum that water flows through.

According to invention disclosed herein on the other hand, there is provided a system comprising toilet, this toilet comprises: the bedpan of no labial surface; Be connected to the accumulator that described toilet is used for supplying to described bedpan flushing water; With water dispenser near described bedpan inwall, described bedpan arranges and is used for receiving described flushing water and comprises two bedpan imports that described bedpan import is in use arranged and is used for week guiding all described water basically in bedpan on the opposite direction of substantial horizontal.

According to invention described herein on the other hand, a kind of toilet is provided, described toilet comprises the bedpan and a pair of opposite water inlet of no labial surface, should in use arrange opposite water inlet and be used on the opposite direction of substantial horizontal flowing into water in the toilet around the inner surface guiding of bedpan, and this toilet also comprises the 3rd water inlet, it is arranged in described a pair of opposite water inlet top and is in therebetween, described the 3rd water inlet in use arrange be used for above described a pair of water inlet and between the position guide a spot of water to flow in the bedpan.

The specific embodiment

Referring to accompanying drawing, comprise the bedpan 1 and the accumulator (not shown) that is used for to described bedpan supply flushing water of no labial surface according to the toilet of invention.Shown in Fig. 2,4 and 5, the inwall global formation of water dispenser or equipment 3 and bedpan 1.Followingly discuss described water dispenser in more detail with reference to Fig. 7 A and Fig. 8.

As shown in Figure 4, water dispenser 3 comprises pipeline 4, is used to receive the water that is supplied to bedpan.It is communicated with water tank (not shown) fluid.This water dispenser also comprises two

imports

5 and 6 of leading to bedpan, to be used for from pipeline 4 to bedpan supply water.Described import can be any suitable dimensions, depends on the feature of the system of specific hydraulic pressure and installation toilet.In an example, the diameter of import is 20 millimeters, and tolerance is ± 1 millimeter.

In optional embodiment,

outlet

5 and 6 can be formed by a plurality of apertures.

Bedpan comprises a pair of water guiding piece near water dispenser 3.Described guiding piece is first and second guiding

flange

7 and 8 of symmetry.Alternatively, also can use single flange.

Referring to Fig. 4, each

flange

7 and 8 has the near-end of close

respective inlets

5 and 6 again.Then, flange circumferentially extends to far-end from

corresponding inlet

5 and 6 around the inner rim of bedpan 1.Shown in Fig. 3 and 4,

flange

7 and 8 peripheries around inwall extend, and their far-end is being positioned at the some place mutually remittance relative basically with

water dispenser.Flange

7 and 8 width are also towards far-end little by little narrow down (tapered).

Figure 6 illustrates the example of the best taper of

flange

7 and 8, wherein, the width of

flange

7 and 8 the most

close import

5 and 6 near-end is about 58 millimeters, and is narrowed about 3 millimeters gradually at the width of the far-end at

flange

7 and 8 joint places.

In optional embodiment, far-end can only extend along the part of inner peripheral wall, and does not therefore converge mutually at a common point place.Flange can change according to the requirement of system and the size of bedpan along the distance that periphery extends.

Fig. 7 A shows the section of toilet one side, and Fig. 7 B shows the sectional view that closes along the toilet labial surface of the B-B line shown in Fig. 7 A.Shown in Fig. 7 A, flange can have the surface that with respect to the horizontal plane becomes low-angle " a ", so that increase between flush period along the defluent discharge of bedpan inwall, and reduces after finishing flush cycle water and remains in possibility on the guiding flange.The angle a that

flange

7 and 8 is inclined relative to horizontal (shown in Fig. 7 B) for example can be 1 °～15 °.Advantageously, described angle can be bigger near the part place of import at guiding piece, and increase along the length of each guiding piece.

Water dispenser can comprise a part 11 that is arranged between

flange

7 and 8, and described part 11 extends upward from the rear inside wall of bedpan.This has illustrated in Fig. 7 A.In fact, this smooth part is a part that forms the chamber of water dispenser in the bedpan wall.Pair of

sidewalls

12 and 13 intersects and two opposite surfaces of formation that extend back with described part 11 separately, and

water inlet

5 and 6 is arranged in these two surfaces.Fig. 7 A shows the sidewall 13 that comprises water inlet 5.

In addition, as shown in Figure 7A, it is angled that part 11 and relevant sidewall are arranged such that sidewall is arranged to vertical plane.Therefore, the water that flows out from water inlet 5 is directed on the upper surface of water guiding piece 7 and guides along the surface of guiding piece subsequently.

Fig. 8 has shown an embodiment and the relevant size thereof of part 11.As shown in the drawing, each sidewall is 7.5 °～9 ° with respect to the inclination angle of vertical plane.The sectional width of bottom is 39 to 50 millimeters, and the sectional width at top is 56 to 67 millimeters.

Referring to Fig. 5,

flange

7 and 8 also has top guiding flange 9 and 10 again.As discussed above, guiding

piece

7 and 8 supports and sends the water around labial surface from each respective inlets.Upper water guiding

piece

7 and 8 provides the apparent surface who forms short conduit, and water flows into the described short conduit from each import.When water left import, described conduit kept water, and prevented that any from bedpan from overflowing or dabble.When water when import is flowed out, water is stayed on the upper surface of guiding piece 7 and 8.Therefore, upper guides 9 and 10 is arranged to gradually taper in the bedpan wall, thereby makes accessibility and observability the best of bedpan inner surface.

What recognize is, the degree that upper guides is protruded from the bedpan inwall and they are to determine according to the angle that the pressure/flow and the water of water are derived from outlet along the length of bedpan inner surface separately.

In operation, water enters the chamber (being arranged in the back of part 11) that is formed in the bedpan wall, and by

import

5 and 6 flow out to by

lower guide

7 and 8 and each conduit of being limited of upper guides 9 and 10 in.The water of maximum ratio transmits along the upper surface of

flange

7 and 8 and around bedpan.What recognize is that water will flow in the bedpan downwards from these guiding pieces.Arrow shown in Fig. 7 A shows from guiding piece and flows and flow into the water of the cumulative ratio in the bedpan.

In major applications, the type of flow shown in Fig. 7 A is enough to clean the whole surface of bedpan.Yet in some cases, some residue can remain on the part 11 or be following and can not be cleaned by the current shown in Fig. 7 A usually.Therefore, part 11 can have other little flushing hole 14, described little flushing hole 14 and the chamber in fluid communication that is arranged in part 11 back, and water collected in the described chamber before by import 5 and 6.In use, a spot of water (be approximately flushing water cumulative volume 6.5%) from chamber flow out by hole 14 and along the surface of part 11 to dirty.In fact, this position and the bedpan inwall below part 11 are washed in described flushing hole.The increase of flushing hole 14 has advantageously increased the total surface area that bedpan is rinsed between flush period.In this layout, about 93.5% flushing water flows through import and flows around bedpan.Be positioned at the center of part 11 though Fig. 7 A shows flushing hole towards base portion, flushing hole 14 can be positioned at the more eminence on the part 11, to allow having more most surface area to be rinsed in its lower section.Advantageously, as described in this article, flushing hole can be arranged in two imports top and between them to be used for flushing water, this itself has constituted invention.

Alternatively or additionally, the amount that reciprocal recess that can be by increasing position 15 shown in a pair of Fig. 7 of the being positioned at A and 16 places or passage increase the surface area that is rinsed.These recesses are arranged to the water of small scale is sent to the position of part below 11 from each guiding piece.

In use, when the user started the flushing machine of toilet, water was fed to the pipeline 4 from the accumulator (not shown).Then, water enters in the chamber that is arranged in part 11 back and by import 5 and 6.The all basically water inner rims around bedpan 1 on the opposite direction of level of described import guiding

flow.Guiding flange

7 and 8 has formed second half of passage, the water that guiding is flowed out from outlet on the opposite direction of substantial horizontal, and prevent from when water at first enters bedpan, on the short part of water channel, to overflow from the top of toilet.

When water during by

import

5 and 6, water forms in the opposite direction the first and second essentially horizontally opposite current that flow around the bedpan inner rim, shown in the arrow among Fig. 4.

Then, at least a portion of opposite current is piled up being positioned at that part of place of bedpan inwall relative basically with water dispenser 3.The particular location that current bump on the bedpan wall can change according to the specification of pressure that applies feedwater and bedpan.

When collision, first and second current have formed water column, and are guided towards the inwall rear portion that is close to water dispenser 3 backward.When described water collided with the water that is in the bedpan bottom, the impact and the water yield were enough to make the water that remains in the toilet U-bend to move, thus and " flushing " toilet.

When the flange of various width of use and tapering is tested, find that surprisingly the size optimum shown in Fig. 6 is used to make water to flow around the bedpan front portion and to form and is applicable to the powerful water column that starts flush toilet.Yet flange is not limited to these sizes, because also can use many modification to produce the powerful water column that is applicable to flush toilet.

In the embodiment that has with the flushing water import in a plurality of holes, can on each direction, form plural current, yet these current also will still center on the inner rim guiding of bedpan and work in a manner described on essentially horizontally opposite direction.

Though the major part of first and second current is piled up being positioned at the anterior place of the bedpan inwall relative with water dispenser, but the part of first and second current is also overflowed from the edge of water guiding piece, to play the effect that flushing is positioned at following a part of inwall.This illustrates by the current arrow among Fig. 7 A.When inlet pressure descended and flow out the coverage area minimizing of current, this effect had been strengthened when ending up near flush cycle, fell from the side of flange to allow water.

In guiding flange 7 and embodiment that 8 far-end does not converge mutually, far-end and flushing that the part of first and second current can flow through its respective guide flange are positioned at following a part of inwall.

In the embodiment that comprises flushing hole 14, flushing hole allows the flushing water flushing of small part to be positioned at following rear inside wall position.At duration of test, for 4.5 liters flush cycle, about 6.5% flushing water flows out from water dispenser by flushing hole 14.The effect of drain hole can also be advantageously played in flushing hole 14, is used for discharging the water of the chamber that collects in water dispenser during flush cycle.Therefore, can reduce the water accumulating volume of after flushing, staying in the system.This is useful, because ponding is the potential breeding ground of microorganism.

What recognize is that described herein and graphic various features, aspect and embodiment can use by any suitable combination, and have formed the part of invention.
