Technical field
The present invention relates to toilet, relate in particular to the toilet without labial surface.
Background technology
In the prior art, the quite a long time can be used the toilet of various types.In Fig. 1, by section, shown the example of a traditional toilet.The toilet labial surface (Reference numeral B) that traditional toilet generally comprises bedpan or pond (Reference numeral A) and extends around bedpan top.During flush toilet, water is imported to the rear portion of bedpan from inlet tube.Enter toilet water major part by the vertical direction along the rear wall of bedpan downwards and towards the bottom-boot of bedpan, at the place, bottom of bedpan, water enters soil pipe or U-bend (as shown in the arrow in Fig. 1)., compared with the water inlet of small scale, around the labial surface of toilet, flow, described labial surface is formed by inverted U-shaped conventionally, to allow water to flow downward to rinse the inner surface of bedpan along the inner surface of bedpan by aperture as shown in the figure meanwhile.Water enters in bedpan along channel flow and by these holes.
Although traditional toilet is very universal and have advantage, there are a lot of significant shortcomings in the toilet that includes labial surface.For example, due to the profile of traditional toilet labial surface, for microorganism and bacterium provide, grow place and provide collection region for refuse.The profile of described labial surface also can make to be difficult to effectively clean 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 around this accumulation be antihygienic, to be that public lavatory, hospital etc. are special worry for this.Referring to for example GB 2431937, known in the prior art have a toilet of labial surface of improvement, to attempt to solve problem described in some.
But the design of prior art could not provide a kind of toilet device of being combined to provide efficient and effective flushing action with toilet, thereby can not substantially eliminate the possibility that microorganism and/or bacterium accumulate or breed in labial surface or around labial surface.Therefore, need a kind of toilet that can overcome the toilet of described problem and there is improved spatter property.The present invention makes in the situation that having considered at least in part described problem and having considered traditional toilet shortcoming.
Summary of the invention
According to first aspect, a kind of toilet is provided, comprise bedpan and a pair of water inlet without labial surface, described water inlet is in use arranged in the contrary direction of substantial horizontal around the inner surface guiding of the bedpan water in all inflow toilets substantially.
According to the present invention, by described two water inlets only in contrary and substantially horizontal direction guiding receive all flushing water substantially in toilet, that is, water is not from import, directly to guide downward inflow bedpan as in traditional toilet.In the prior art, as shown in the arrow in Fig. 1, the whole water substantially receiving in bedpan is guided towards U-bend, to produce necessary flushing action.Flatly guide all water to make on the opposite side of bedpan, to have produced flushing water column, thereby described flushing water column clean the inner surface of bedpan and produce essential flushing water column.Use without any the toilet of kind labial surface make can microorganism accumulation, bacterium and material region around of bedpan reduce to minimum, and the observability the best that makes in addition bedpan inside easily and easily checks allowing.
In the contrary direction of level, guide substantially all water not consider in the prior art, because be traditionally, by the U-bend towards bedpan, directly guide a large amount of water to produce necessary flushing action downwards.Should be understood that term " substantially all " is to be used to refer to nearly all water that enters toilet, but some water can be stayed in toilet and/or evaporation etc.
Term " without labial surface " is to be used to refer to the surperficial a kind of bedpan that overhangs that upper surface around labial surface does not extend in this article.By removing the surface that overhangs, greatly improved the observability of bedpan inside.In addition, improved the entering in order to cleaning of bedpan.
Water can be directed in bedpan by water dispenser, and described water dispenser for example can protrude from the inwall of bedpan at bedpan rear portion.Alternatively, water can lead in bedpan from a pair of recess, and described recess is formed in bedpan wall and is in use disposed to flatly guide as mentioned above water.Import is formed into and in the recess on nightstool wall, has further removed perhaps relevant to the water inlet protruding meeting growth microorganism and the edge of bacterium.
In order to make to rinse and cleaning action maximum, can flushing water be imported in bedpan in the upper edge of the bedpan near without labial surface.The bedpan area maximum that water flows through flushing water is introduced at top at bedpan, and makes unwashed bedpan area minimum.
Each in two contrary water inlets can be formed by the single mouthful of institute that is disposed to water to lead in bedpan.Alternatively, each mouthful can be formed by multiple hole, and each hole is disposed to water to lead in 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, to meet on the opposite side of bedpan and to collide.
In order advantageously to make water circulate around whole bedpan, bedpan can be furnished with water guiding piece or the flange of a pair of circumferential extension, each guiding piece or flange have first end, and described first end is close to one of them flushing water import and is in use disposed to and in bedpan, guides or transmit flushing water in the contrary direction of substantial horizontal week.
In use, water flows out from each import, and by the top along each water guiding piece and guide around bedpan.Each guiding piece has advantageously prevented that water from flowing by the mode in traditional toilet,, directly flows to U-bend downwards that is.In use, guiding piece transmits water from each import and around the inner surface of bedpan, so that water collides and produce " water column " on the opposite side of bedpan, described " water column " flows in U-bend then.The configuration of guiding piece has advantageously provided the surface that can transmit water in the above.In addition, because there is not overhang surface or labial surface, so guiding piece, without any hidden parts, and can easily and easily check cleannes.As mentioned above, advantageously, guiding surface also facilitates and is easy to cleaning, because burnisher is easy to approach.
Recognize, can not observe easily in the prior art the inner surface of toilet.Even in the list of references of mentioning in the above, set labial surface has hindered the inner surface that fast and easily checks bedpan.
On the other hand, a kind of toilet is provided, described toilet comprises without the bedpan of labial surface and is arranged to water to lead to the water dispenser in 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 and 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 water that enters bedpan.Each guiding piece or flange can be advantageously formed as the surface of protruding from the inner surface of bedpan, that is, with the inner surface of bedpan be one.Therefore, can easily form guiding piece by traditional manufacturing technology.
Each guiding piece/flange is by the near-end near respective inlets and forms 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, to 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 the inspection to toilet easily (for cleannes) in addition, 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 flange when bedpan flows at water.Guiding piece can change, for example, along whole or a part of inclinations of guiding piece length, with a part that allows the water mobile along each guiding piece, from guiding piece inward flange, overflow, to flow on the bedpan inwall below guiding piece.In fact, around a part of water of the inner guiding of bedpan, be allowed to being roughly downward through the inner surface of bedpan from guiding piece on vertical direction, to rinse the inner surface of bedpan.Recognize from the mobile water of guiding piece, will there is the component motion of approximate horizontal when the edge flowing from guiding piece by which, therefore will be around bedpan circulation when water flows from guiding piece.Like this, when water is around bedpan surface and while being downward through bedpan surface, rinsed easily the inner surface of bedpan.This can be by a whole or part for flange being arranged to leaving water plane has low-angle so that a part of water flows through flange inner surface realizes.Flange can for example become the angle of 1 to 15 degree with horizontal plane.
Alternatively or additional, this can be by making each flange realize having the first width and have the second less width at the far-end of flange near respective inlets place.Advantageously, guiding piece can be arranged to from near-end tapered to far-end, so that the bearing surface of water flow narrows around the periphery of bedpan.The far-end of guiding piece can be on bedpan periphery substantially the some place relative with water dispenser converge mutually, to guarantee transmitting water around the whole periphery of bedpan.
In order to optimize the cleaning of bedpan and the flushing action to toilet with the flushing water of standard volume, guiding piece can have the first end near each flushing water import, its guiding width, between 40 millimeters to 65 millimeters, more preferably between 50 millimeters to 60 millimeters, and most preferably is 58 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 rinsing water column, has optimized the cleaning action of bedpan simultaneously.Also can be by making the roughly symmetrical generation of optimizing water column of inside of bedpan.
Depend on the size of bedpan, taper also can be arranged to make guiding piece to stop at the place, a part of path of bedpan periphery, that is, and and guiding piece narrow being reduced in bedpan wall gradually.Recognize, in this layout, allow to flow in bedpan along the mobile water augmenting portion of each guiding piece.
Guiding piece can be advantageously arranged to guide two reciprocal current, to becoming diagonally and colliding on relative position with inlet device, that is, and at the front shock of bedpan.Should be appreciated that, the height (for the height of the liftoff plate of bedpan) of two current points of impingement depends on the ad hoc structure of guiding piece and the flow of water.Select the structure of guiding piece so that the water of enough ratios, at the front shock of bedpan, and makes water be guided towards the rear portion of toilet in the direction roughly crossing backward bedpan by means of the momentum of water." 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 bedpan bounce-back.
Part place at each guiding piece near each flushing water import, as mentioned above, described import can be formed in the recess of bedpan inwall.Recess is actually that the soffit that limited by tapered guide part and upper surface corresponding thereto form, described upper surface plays the effect of lid, to prevent from spraying from any water of each water inlet the top of bedpan when water leads on guiding piece with maximum flow.Advantageously, this surface narrow being reduced in bedpan wall gradually, 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 disposed to allow a small amount of water to flow through two bedpan parts between contrary 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 to flow through this part of bedpan.For example, described two contrary imports can be configured to receive and exceed 90% the water (each reception 45%) in toilet that receives, and the remaining water yield flows to and is arranged in two contrary imports tops and in flushing import therebetween.Described flushing import can be arranged in any suitable At The Height with respect to bedpan upper surface, but preferred arrangements is at close upper surface place, so that the bedpan area maximum that water flows through.

Although various improvement and alternative form are allowed in invention, specific embodiment shows as example in the accompanying drawings and describes in detail in this article.But, should be appreciated that, accompanying drawing and detailed description thereof are not for invention being limited to disclosed special shape, on the contrary, invention is will contain all improvement, the equivalent dropping in essence of the present invention and the scope limiting as claim and substitute.
The specific embodiment
Referring to accompanying drawing, according to the toilet of invention, comprise without the bedpan 1 of labial surface with for the accumulator (not shown) to described bedpan supply flushing water.As shown in Fig. 2,4 and 5, the inwall global formation of water dispenser or equipment 3 and bedpan 1.Referring to Fig. 7 A and Fig. 8, discuss in more detail described water dispenser.
As shown in Figure 4, water dispenser 3 comprises pipeline 4, for receiving 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, for the supply water from pipeline 4 to bedpan.Described import can be any suitable size, 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 multiple apertures.
Bedpan comprises a pair of water guiding piece near water dispenser 3.Described guiding piece is the first and second symmetrical guide flanges 7 and 8.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 import 5 and 6 around the inner rim of bedpan 1.As shown in Figures 3 and 4, flange 7 and 8 peripheries around inwall extend, and their far-end converges at relative some place substantially mutually being positioned at water dispenser.The width of flange 7 and 8 is also towards far-end little by little narrow (tapered).
Figure 6 illustrates the example of the best taper of flange 7 and 8, wherein, the width of the near-end of the most close import 5 and 6 of flange 7 and 8 is about 58 millimeters, and is narrowed gradually about 3 millimeters at the width of the far-end at flange 7 and 8 joint places.
In optional embodiment, far-end can only extend along a part for inner peripheral wall, and therefore at a common point place, does not converge mutually.The distance that flange extends along periphery can change according to the size of the requirement of system and bedpan.
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.As shown in Figure 7 A, flange can have the surface that with respect to the horizontal plane becomes low-angle " a ", to increase along the defluent discharge of bedpan inwall between flush period, and reduces to remain in the possibility in guide flanges completing water after flush cycle.The angle a (shown in Fig. 7 B) that flange 7 and 8 is inclined relative to horizontal can be for example 1 °～15 °.Advantageously, described angle can be larger near the part place of import at guiding piece, and along the length of each guiding piece and increase.
Water dispenser can comprise the part 11 being arranged between flange 7 and 8, and described part 11 is upwards extended 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 bedpan wall.Pair of sidewalls 12 and 13 is and extend back formation two contrary surfaces crossing 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 so that sidewall is arranged to vertical plane.Therefore the water, flowing out from water inlet 5 is directed into the upper surface of water guiding piece 7 and along the surface of guiding piece, guides 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 guide flanges 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 described short conduit from each import.When water leaves import, described conduit keeps water, and prevents that any from bedpan from overflowing or dabbling.When water flows out from import, 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 bedpan wall, thereby makes accessibility and observability the best of bedpan inner surface.
Recognize, the angle that upper guides is the derivation from outlet according to the pressure/flow of water and water along the length of bedpan inner surface from degree and they of bedpan inwall protrusion is separately determined.
In operation, water enters the chamber that is formed in bedpan wall (be arranged in part 11 after), and by import 5 and 6 flow out to by lower guide 7 and 8 and each conduit of limiting of upper guides 9 and 10 in.The water of maximum ratio is along the upper surface of flange 7 and 8 and around bedpan transmission.Recognize, water will flow into downwards in bedpan 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 bedpan.
In major applications, the type of flow shown in Fig. 7 A is enough to clean the whole surface of bedpan.But in some cases, some residue can remain in part 11 or below and conventionally and can not be cleaned by the current shown in Fig. 7 A.Therefore, part 11 can have other little flushing hole 14, described little flushing hole 14 be arranged in part 11 chamber in fluid communication below, water collected in described chamber before by import 5 and 6.In use, a small amount of water (be approximately flushing water cumulative volume 6.5%) flows out by hole 14 from chamber and along the surface of part 11 to dirty.In fact, this position and the bedpan inwall below part 11 are rinsed 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.Although Fig. 7 A shows flushing hole, be positioned at the center of part 11 towards base portion, flushing hole 14 can be positioned at the higher height in part 11, to allow having the in its lower section surface area of greater part to be rinsed.Advantageously, as described in this article, flushing hole can be arranged in two imports top and between them for flushing water, this itself has formed invention.
Alternatively or additionally, can increase by increasing the reciprocal recess at 15 and 16 places, position shown in a pair of Fig. 7 of being positioned at A or passage the amount of the surface area being rinsed.These recesses are arranged to the water of small scale to be sent to the position of part below 11 from each guiding piece.
In use, when user starts the flushing machine of toilet, water is fed to pipeline 4 from accumulator (not shown).Then, water enters and is arranged in part 11 chamber below and by import 5 and 6.Described import guides substantially all water inner rim around bedpan 1 in the contrary direction of level to flow. Guide flanges 7 and 8 has formed second half of passage, the water that guiding is flowed out from outlet in the contrary direction of substantial horizontal, and prevent from the short part of water channel, from the top of toilet, overflowing when first water enter bedpan next.
When water is during by import 5 and 6, water forms the first and second essentially horizontally contrary current that flow around bedpan inner rim in the opposite direction, as shown in the arrow in Fig. 4.
Then, at least a portion of contrary current relative bedpan inwall part place is piled up substantially being positioned at water dispenser 3.The particular location that current bump on bedpan wall can be according to applying the pressure of feedwater and the specification of bedpan changes.
When collision, the first and second current have formed water column, and towards the inwall rear portion of contiguous water dispenser 3, are guided backward.When described water and the water collision in bedpan bottom, impact and the water yield are enough to make the water remaining in toilet U-bend to move, thus and " flushing " toilet.
When the flange that uses various width and tapering is tested, find that surprisingly the size optimum shown in Fig. 6 is for making water flow and to form the powerful water column that is applicable to start flush toilet around bedpan is anterior.But flange is not limited to these sizes, because also can produce the powerful water column that is applicable to flush toilet by many modification.
Having in the embodiment of the flushing water import with multiple holes, can in each direction, form plural current, but, these current also by still in essentially horizontally contrary direction around the inner rim guiding of bedpan and work in a manner described.
Although the major part of the first and second current is piled up being positioned at the anterior place of the bedpan inwall relative with water dispenser, but a part for the first and second current is also overflowed from the edge of water guiding piece, to play the effect that is positioned at a part of inwall below of rinsing.This illustrates by the current arrow in Fig. 7 A.When inlet pressure declines and flow out the coverage area minimizing of current, this effect has been strengthened when approaching flush cycle ending, to allow water to fall from the side of flange.
In the embodiment not converging mutually with 8 far-end in guide flanges 7, far-end and flushing that a part for the first and second current can flow through its respective guide flange are positioned at a part of inwall below.
Comprising in the embodiment of flushing hole 14, flushing hole allows the flushing water of small part to rinse the rear inside wall position being positioned at below.At duration of test, for the flush cycle of 4.5 liters, 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, for discharging the water of the chamber that collects in water dispenser during flush cycle.Therefore, can reduce after rinsing and stay the water accumulating volume in system.This is useful, because ponding is the potential breeding ground of microorganism.
