Description
Technical field
The present invention relates to a flush toilet that is used for human defecation and other refuse.The invention still further relates to such flush toilet, it can prevent to stop up, improve scouring capability, and supply has the washing water quantity than macro-energy.
Background technology
Flush toilet is well-known with removing refuse.Usually, flush toilet comprises three systems, and they are worked together and implement flushing action.These systems are (1) bowl siphon, (2) flushing mechanism, and (3) refill mechanism.These three system coordination ground work realize the washing capacity of flush toilet.
Siphonage is used for fluid and refuse are transported to from the bedpan of high height the soil pipe of lower height.The runner of toilet assemblies is designed to: begin siphonage when waterborne in the bedpan is raised to certain height.Syphon itself is the U-shaped pipe of putting upside down, and it is drawn into soil pipe with water from bedpan.When flush toilet was washed by water, water was extracted out from bedpan and is entered in the syphon.Because the effect of flushing mechanism and refill mechanism, the flushing action is started because of water enters bedpan.When bath, bedpan is filled the water from high level cistern soon, and it causes syphon to fill up water, forms a barometric gradient in pipe.Fill out the bedpan of pouring water in siphonal beginning part and produce higher pressure, cause water and refuse to be pushed in the soil pipe by pipeline.
Usually, the water tank that is positioned at bedpan back top contains water, its be used for starting from bedpan to the sewer line siphonage, and be back in the bedpan with clear water.When a user desired flush toilet, he promoted the flush handle of water tank outside downwards, and this flush handle is connected to a removable chain or a lever in water tank.When flush handle is pressed, a chain or lever in its mobile water tank, it is used for promoting and opening flushing valve, causes water to flow in the bedpan from water tank, therefore, the flushing of starting toilet.
In the design of many flush toilet, water had not only directly flowed in the bedpan but also had been assigned to the edge of toilet basin.The edge has several apertures usually to allow the inflow of water in the bedpan.Water at a good pace is discharged in the bedpan, and the current that flow in the bedpan from water tank continue about 2 to 4 seconds usually.The groove that water is downward through from the edge in the bedpan side enters in the macropore of closestool bottom, is referred to as siphon jet usually.The water that siphon jet discharges the overwhelming majority enters in the syphon, with the starting siphonage.Siphonage extracts all water out from bedpan and refuse enters in the syphon.Refuse and water continue, to be discharged into then in the sewer line that is connected closestool bottom by being referred to as a zone of trap by the siphonal other end of U-shaped.
In water-rinsing process, in case its content water (clear water) of water tank emptying, flushing valve promptly cuts out, and drops to certain residual volume in the present water tank of a ball float mechanism, and it starts opening of discharging valve.Discharging valve not only provided clear water to be provided to bedpan to water tank but also by independent current.At last, the water of water tank is filled enough height and is risen to cause ball float, closes discharging valve thus.At this moment, flush cycle is finished.
Yet government department constantly requires the city tap-water user to reduce water supply volume.In recent years, very big notice has focused on the needed water supply volume of minimizing flush toilet flush operation.For this point is described, according to the requirement of government department, the toilet employed water yield of at every turn washing by water is reduced to 5.5 Jie's logical sequences/time (at the bottom of nineteen sixty) from 7 Jie's logical sequences/time (before nineteen fifty), is reduced to 3.5 Jie's logical sequences/time (1980) again.
In the past, toilet designs has taked the whole bag of tricks to make great efforts to meet the requirement of this reduction water yield, but it is very difficult always to reach super flush performance.Therefore, require to provide to satisfy flush toilet compulsory diminishing requirement, that help flush operation always, simultaneously, provide raising and super flush operation.
Producing one more reliably, more effectively and more in numerous industry of the gravity water closet of powerful 1.6 Jie's logical sequences (6 liters), a kind of method of more effectively removing refuse from toilet basin is, in the flush operation process, and the hydraulic energy that increase can supply.Yet, adopt that the purging method of normally used edge can not improve the hydraulic energy that can supply in the existing toilet, when the path of water when two relative directions flow through the edge of toilet, thus, reduced the hydraulic energy that can supply.Therefore, require to provide a toilet that can increase the hydraulic energy of edge bath.
The minimum that the requirement of government department at present also forces the flush lever of flush valve assemblies to have 1 second " is pressed " time, is no more than the total water or the draining of each bath of above-mentioned 1.6 Jie's logical sequences or 6 premium on currency.Water has found that, if can then can improve the feature of the hydraulic performance of toilet significantly less than the time of releasing emptying from water tank of 1 second (be preferably 0.5-0.6 second).Therefore, also find to require to provide a kind of flush toilet, it discharges the action of flush lever, " presses " time (1 second) in the minimum of forcing flush lever, be no more than before the compulsory total water end of each bath of 1.6 Jie's logical sequences (6 liters) water, make opening of valve to close.
In the forming process of the present application, examine and tested some kinds of flush toilet.And made the ability that bath is checked in test.In order to determine the obstruction and the nonclogging characteristic of these toilets, wash various objects by toilet, comprise table tennis, thick wadding, unsteady acrylic sphere, foam sponge, and the rubber tube that floats.These objects are used for simulating the size and dimension of various refuses.
The toilet designs of all tests all has some common problem, but degree is not quite similar.At first, several models have blockage problem.In most these toilets, this problem can be summed up in the point that in the not enough trap of size.The second, when the refuse of a great deal of was arranged in the bedpan, the design of some toilet then can not be cleaned bedpan in single flushing.The 3rd, some toilet uses the flushing flow path of a symmetry to come to provide flow to the edge, and they may reduce the efficient of toilet.The 4th, the flushing valve in some toilet can not provide the water supply of not only fast but also the high water yield from water tank.At last, many toilets produce suitable noise in water-rinsing process.These tests are confirmed such toilet assemblies need be provided, and it reaches maximum trap but does not weaken siphonage.
Therefore, requirement provides a toilet, and the possibility that bath that its permission is more quiet and minimizing are stopped up increases the bath ability, and the bath effect of passing through the mobile formation in edge one eddy current of an asymmetrical injection stream.This flush toilet comprises a flushing valve, and it is reduced to the loss of waterpower minimum and allow current successfully to carry out the transition to the water supply of injection stream and edge gateway from flushing valve.

In order to improve the performance of flush efficiency and toilet, a pair of rhone 28a and 28b are arranged in the edge gateway 24, so that the flushing water that in asymmetric runner, passes through by edge gateway 24, can be from edge gateway 24 by being assigned in the toilet basin such as one of a plurality of rim openings of 26a, b, c and d or by one of paired rhone 28a and 28b.These rhones 28a and 28b directly are discharged into flushing water in the toilet basin 20 with two current (seeing arrow B and C among Fig. 3), two current form the eddy current effect of a brute force, provide bigger siphon energy (will describe in detail hereinafter) to removing refuse.As shown in Figure 3, one of paired rhone 28a is arranged in about halfway of edge gateway 24, and second rhone 28b is arranged on the back portion 29 of toilet basin 20.
In aforesaid flush operation process, water is downward through the side of bedpan from rim openings 26a, b, c and d, or flow directly in the toilet basin 20 by rhone 28a and 28b, towards the big tap 30 at the place, bottom that is arranged on toilet basin 20, it is referred to as siphon jet.Flushing water also directly is fed in the siphon jet by means of direct injection circulation road 29.It is interior to start a siphonage to trap 40 that siphon jet discharges most water.Siphonage extracts all water from toilet basin and refuse enters in the trap 40, then, is discharged in the sewer line at 31 places, bottom that are connected toilet 10.
In water-rinsing process, in case its predetermined volume of water tank emptying then starts the discharging valve (not shown) and opens.Discharging valve not only provided clear water to be provided to toilet basin 20 to water tank 12 but also by independent current.At last, the water of water tank 12 is filled to a water level and is caused the ball float of flush valve assemblies 14 to rise, and closes discharging valve thus.Current flush cycle is finished.
Describe all parts of flush toilet 10 of the present invention below in greater detail.
As shown in Figs. 4-6, flush valve assemblies 14 of the present invention comprises the bath covering 34 of a valve body 32, a predetermined length, and one " stroke release " or " losing motion " mechanism 36.Flush valve assemblies 14 its water tanks of installing of permission keep the water of a scheduled volume, and supply water as a pipeline, are fed to the trap of toilet by the passage in the toilet.Valve body 32 comprises sleeve part, an end 38, and it is fixed to water tank or flush toilet by a screw element 39 that is provided with along the outer peripheral surface 40 of bottom supporting part 41.
Flushing valve covers or shut-off block 34 is installed coaxially and slidably with respect to valve body 32, and like this, when removing flushing valve from valve body 32 and cover 34, valve opening 50 is formed on valve body 32 and flushing valve covers between 34.Flushing valve covers 34 and moves between one first resting position and a second place slidably, in first static position, wherein, flushing valve covers 34 and is seated on the ring-shaped valve seats 52 of sleeve part, the end 38 of valve body 32, so that water can not be by valve opening 50 (seeing Fig. 4 and 8), and at second place place, wherein, flushing valve covering 34 is removed from the ring-shaped valve seats 52 of the sleeve part, the end 38 of valve body 32, so that water can be by valve opening 50 (seeing Fig. 5 and 9).The fastening position of valve opening 50 prevents that flushing water from flowing into the valve opening, till by means of flush lever valve being activated.The open position of valve opening 50 allows flushing water to flow to into the valve opening, and advances in the interior passage of the attached with it flush toilet of water tank.
As hereinafter setting forth, flush valve assemblies 14 of the present invention reaches the bigger energy of washing water quantity, and it provides bigger energy to remove refuse again from toilet basin.In order to obtain the result of such advantage, the sleeve part, the end 38 of permeability cell comprises a radial inlet 58, and the diameter a that it has is approximately 4.5 inches, and the arc radius b that has on the preceding limb 58a that is combined in inlet is 3/4 " (see figure 7).
Its result, the radial inlet 58 of sleeve part, the end 38 forms one 0.95 valve opening emission factor.Emission factor is the actual flow area of open area and the ratio between the static aperture area.In practice, the emission factor of opening is high more, and then the hydraulic energy of the water by opening is also high more.Be not to provide a radial inlet to import the angle at the valve opening part as the present invention, then the emission factor of the valve opening of typical prior art is approximately 0.6.Therefore, the flushing water of the valve opening of the flush valve assemblies 14 by flush toilet of the present invention emits energy, the energy of emitting greater than the flushing water of the existing valve module by above-mentioned prior art.Because the cause of the radial inlet 58 of the sleeve part, the end 38 of above-mentioned valve body 32, the flow behavior and the fluid ability that are contained in the flushing water of the flush valve assemblies in the flush toilet of the present invention are improved.Therefore, in passing through the flushing water of this flush valve assemblies, produce bigger energy, so that remove the refuse in the toilet basin.
Enter in the water tank in order to adapt to unconfined overflow, flushing valve covering 34 comprises a funnel shaped inlet 59 at bath 60 places, ingate.The horizontal axis that this falred entrance covers with respect to flushing valve has a predetermined importing angle β (see figure 7).
As shown in the figure, Fig. 4 especially, flushing valve cover 34 can comprise a top 34 ', a bottom 34 ", and therebetween part 34 , it can be the part of a step or an inclination shape.The diameter on top 34 ' can be less than bottom 34 " diameter.In addition, covering diameter that the lip ring 64 of 34 basal surface setting has along flushing valve can be greater than bottom 34 " diameter.
The diameter of sloping portion 34 and lip ring 64 can design and/or select like this: in water filling process, make a masterpiece be used in flushing valve and cover on 34, it is enough to spur flushing valve and covers 34 downwards, and causes and forms a suitable sealing.Such power can be that the pulling flushing valve covers 34 and the power of the needed minimum of appropriate seal is provided downwards.In addition, select bottom 34 " diameter, be flushing valve and cover 34 buoyancy that requirement is provided.Such buoyancy can influence flushing valve and cover for 34 time cycles that stay open.
Therefore, flushing valve covers 34 can provide desirable buoyancy, and can apply minimum pulling force, and when the flushing valve covering moves to its first resting position, provides a suitable air-proof condition.In addition, when flushing valve covers 34 from it when the position moves to its first resting position on second, close and appropriate seal valve opening 50 needed pulling force by reducing, also can improve the fluid ability of the flow behavior and the flush valve assemblies 14 of flushing water of the present invention.
In view of the above, in the flush valve assemblies 14 in being contained in flush toilet of the present invention, annular plate valve sealing 52 is arranged in the bath exhaust openings 61 in downstream of radial inlet 58.Shown in Fig. 6 and 7, lip ring 64 is provided with along the external peripheral surface 63 of flushing valve covering 34, and when flushing valve covering 34 was positioned at its first resting position, flushing valve covered 34 and is seated in the recessed ring-shaped valve seats 52.
When flushing valve covers 34 on first resting position and second between the position when mobile, in order to lead suitably with respect to valve body 32 and to align flushing valve covering 34, flushing valve covers 34 and comprises cylindrical tube 68 in one second, by means of a plurality of web member (not shown) that radially are provided with of bridge joint between the inwall spare 70 and second cylindrical tube 68, cylindrical tube is fixed to flushing valve and covers on the inner peripheral surface of the vertical wall spare 70 that 34 inside hangs down in described second.Cylindrical tube 68 is fitted on first cylindrical tube 46 of valve body 32 in second, and like this, when flushing valve covers 34 on its first resting position and second between the position when mobile, flushing valve covers 34 by guiding suitably and aligns with valve body 32 exactly.
When flushing valve covering 34 turned back to its first resting position, this guidance set of being made up of first and second cylindrical tubes 46 and 68 also helped seal valve opening 50 suitably respectively.The lip ring 64 that this guidance set is guaranteed to be fitted in the flushing valve covering 34 is properly seated onto on the ring-shaped valve seats 52 of valve body 32 in first resting position of flushing valve covering 34.
In order to reduce hydraulic loss and the further flow behavior that improves flush valve assemblies 34, valve body 32 comprises the structure that farthest reduces flow resistance.This flow resistance reduces parts and comprises a plurality of taper web member 72a, 72b, 72c, and they are disposed radially between the inner peripheral part 73 of the sleeve part, the end 38 of first cylindrical tube 46 and valve body 32.As shown in Figure 7, web member 72a, the 72b of each taper, 72c are composed as follows: a low height part 75a, it is at the place, end towards first cylindrical tube 46, up to the height part 75c that arrive to extend, it is at the place, end towards the inner peripheral part 73 of sleeve part, the end 38 by a tapering part 75b hoisting depth for it.Adopt such design, it is minimum that the turbulent flow of the flushing water by valve outlet opening 61 can be reduced to.
If flushing water does not flow with layer flow mode, then also can cause hydraulic loss.Laminar flow can go to pot because of water refluxes in flush valve assemblies 14.In order in the flush operation process, to reduce the backflow of flushing water, must provide flushing valve to cover 34 enough buoyancy, so that flushing water can be drained suitably.
When flushing valve cover 34 move to from its first resting position its on second the position when realizing suitable flushing water discharging, in order to provide flushing valve to cover 34 buoyancy, a flotation inner chamber 76 is respectively formed between the interior and outer wall spare 70 and 78 that hangs down of flushing valve covering 34.
In typical flush valve assemblies, flushing valve covers 34 first resting positions of cutting out from valve opening 50 by means of flush lever 18 at first and moves to the second place that valve opening 50 is opened.The user moves this flush lever 18 between first resting position and the second place, so that the operation flushing valve covers 34 it is being moved on first resting position and second between position.It is 1 second that the minimum time of " pressing " of flush lever is forced in the requirement of government department at present.Yet the water time that the valve opening stays open before the emptying from water tank is long more, and the energy that dissipates in the flush cycle process is big more.
Flush valve assemblies of the present invention can realize being preferably 0.5-0.6 in second less than shut off valve opening 50 in the time in 1 second, to improve Gong the hydraulic energy of flushing water, thus, guarantees at a good pace to supply the flushing water of scheduled volume and the requirement that is no more than government department.In view of the above, flush valve assemblies 14 comprises the mechanism 36 of one " stroke release " or " losing motion ", described in hereinafter, arrive its second places so that flushing valve covers flush lever 18 when turning back to its first resting position before turning back to its first resting position when flushing valve covers 34, this mechanism 36 discharges flush lever 18 water valve that liquidates and covers 34 effect.
As shown in FIG., trip release mechanism 36 comprises a cam lever 80, a pull bar 82, and the end 82a of pull bar 82 is operably connected to flush lever, and installs slidably with respect to cam lever 80, like this, pull bar 82 and cam lever 80 move in response to the motion of flush lever.One trip dog assembly 90 is also included within the trip release mechanism 36, when pull bar 82 and cam lever 80 moved in first resting position and the second precalculated position time, this mechanism can engage flushing valve and cover 34, when pull bar 82 was moved beyond its second precalculated position, this mechanism can throw off flushing valve and cover 34.
Shown in Fig. 6,7 and 10, pull bar 82 comprises a plurality of extensions such as 77a and 77b, and it comprises a narrow width part 79a, and it little by little increases width and arrives a width segments 79b who widens.This width segments 79b that widens extends outwardly into certain degree, so that they can be received within the admittance opening 100a who is formed by the inner peripheral surface of annular sloping baffle 100 (will explain hereinafter).Each width segments 79b that widens comprises a conjugate foramen 79c in its lower end.
The fastener of trip dog assembly 90 and throw off part and comprise wing keeper 92a, 92b, they are bearing in the conjugate foramen 79c of the width segments 79b that widens of extension 77a and 77b.As shown in Figure 8, when cam lever 80 and pull bar 82 move between the primary importance and second precalculated position together, so that flushing valve covers 34 between first resting position and the second place when mobile, wing keeper 92a, 92b stretches out and engage flushing valve and cover 34.The further motion of cam lever 80 will be limited by this second precalculated position (will be described in more detail below).Because the motion of cam lever 80 is subjected to constraint like this, Fig. 9 illustrates, when pull bar 80 moves through second precalculated position, wing keeper 92a, 92b withdrawal, like this, wing keeper 92a, 92b cover 34 from flushing valve and throw off, and this makes flushing valve cover 34 again and turns back to its first resting position.
Specifically, shown in Fig. 6 and 8, in first resting position of cam lever 80 and pull bar 82, first catch members 93 of each wing keeper 92a, 92b abuts against the leading inclined surface 94a of the central concave cam portion 94 of cam lever 80.The preceding limb 95a of second catch members 95 of wing keeper 92a, 92b abuts against the reduced diameter portion of the central concave cam portion 94 of cam lever 80 and divides 80a.
Each wing keeper 92a, 92b also comprise a bonding part 97, and when cam lever 80 and pull bar 82 turned back to its first resting position, this bonding part 97 pivoted and stretches out, and reorientates thus.When flush lever moved apart its original resting position with cam lever 80 and pull bar 82 at first, first and second catch members 93 and 95 of wing keeper were maintained in the central concave cam portion 94 of cam lever 80.Because the continuing of flush lever 18 pressed, cam lever 80 and pull bar 82 are further to move compoundly, the bonding part 97 of each wing keeper 92a, 92b engages (see figure 7) with annular sloping baffle spare 100, described casing member 100 covers 34 inner peripheral surface 102 from flushing valve and extends, so as with flushing valve cover that 34 first resting positions of closing from bath opening 50 rise to that bath opening 50 opens one second on the position.When cam lever 80 and pull bar 82 moved to second desired height position after flush lever 18 is pressed, an annular base flange 80b who is arranged on the extension on the bottom 80c of cam lever 80 abutted against a bead 46a (see figure 9) that extends internally at the 46b place, top of first cylindrical tube 46 that is arranged on valve body 32.When flush lever 18 continues to press, the further motion of this restriction cam lever 80 and pull bar 82.
When pull bar 82 moves through this second precalculated position because of flush lever 18 continues to press, pull bar 82 stands the additional bias force that applies by spring part 104, this spring is fitted on the top of cam lever 80, and is carried in the center chipware 106 (seeing Fig. 7 and 10) of pull bar 82 and is arranged between a spring button 108 (see figure 10)s of upper end of cam lever 80.Because cam lever 80 is prevented from further motion, so when pull bar 82 moved through second desired height position and bias force and begins to apply, first and second catch members 93 and 95 were stepped out the central concave cam portion 94 of cam lever 80.This causes wing keeper 92a, 92b pivot (see figure 9) again, so that the bonding part 97 of wing keeper 92a, 92b is towards pull bar 80 withdrawal, and covers 34 annular sloping baffle spare 100 with flushing valve and throws off.Its result is because flush lever 18 is connected to pull bar 82, so flushing valve covers 34 and no longer is under the effect of flush lever 18.Because flushing valve covers 34 and is not tied, so flushing valve covers 34 can turn back to its first resting position.Pull bar 82 continues second precalculated position that moves through that it makes progress, and abuts against spring button 108 up to center chipware 106.At this moment, the further motion of pull bar 82 is restricted.
Flush operation causes the shut off valve opening in time second at about 0.5-0.6, and this provides a quickish flush operation, and this operation causes the energy consumption of flushing water to reduce in the flush operation process.Even flushing valve covers 34 and turns back to its first resting position and shut off valve opening 50, pull bar 82 also continues to move up, and meets its compulsory 1 second " pressing " time up to flush lever 18.
In addition, second cylindrical tube 68 of flushing valve covering 34 comprises bead 111 (see figure 7)s that an annular is extended in the top.When the effect that turns back to its first resting position and flush lever when cam lever 80 and pull bar 82 in flush operation had in succession discharged, the cam face 109 of wing keeper 92a, the 92b of withdrawal abutted against the annular of second cylindrical tube 68 and extends bead 111.When cam face is crossed over, be transferred to a bonding station that extends wing keeper 92a, 92b cam, so that first catch members 93 of wing keeper 92a, 92b abuts against the leading inclined surface of the central concave cam portion 94 of cam lever 80, and wing keeper 92a, 92b are pivoted to a position, thus, fastener 97 can engage flushing valve and cover 34 annular sloping baffle spare 100 in flush operation thereafter.
The fluid ability of the flow behavior and the flush valve assemblies of flushing water can improve in the mechanism 36 that comprises " stroke release " or " lose motion " in conjunction with the further feature of above elaboration, simultaneously, reaches with the requirement of compulsory government department and is consistent.
Figure 11 illustrates a flushing inlet, and it provides a transition between water tank 12 and transition passage 22, so that feed the energy maximum of the flushing water in the transition passage 22, but this forms bigger energizing quantity again to remove refuse from toilet basin.As shown in figure 11, flushing inlet 110 has a radial port one 12 at the one end, and it has a preceding limb 112a who tilts, and is similar to the radial inlet 58 of sleeve part, the end 38 of the flush valve assemblies of Fig. 4-9.The diameter that radial port one 12 has preferably is approximately 4 inches, narrows down to 3 inches narrow diameter between its sidewall 114a and the b gradually.The horizontal axis of preceding limb 112a and water tank 12 is inclined to one and imports angle α.
Because the design of this valve inlet, the emission factor of flushing valve is increased to about 0.95.By increasing emission factor, the hydraulic energy of the water by flushing valve is improved.Its result, from the water tank to the edge and the hydraulic loss of the flushing water of injection stream service duct reduce, remove refuse in the toilet basin in flushing water, to form bigger energy.
Figure 12 is another structure with flushing valve of improved hydraulic power characteristic.This flushing valve embodiment comprises that also one has the valve inlet 115 of radial port one 16, but does not require the height as the platform that is used for water tank of the valve inlet 110 of Figure 11.Owing to lack the height of the platform of water tank, so for enough sealings are provided, valve inlet 115 is made by molded rubber.
It is for illustrative purposes that paired Figure 11 and 12 sets forth at this.These designs provide about 7.5 liters/second fill rat to arrive in the transition passage 22.Know easily as those skilled in the art, the flushing valve such as the flush valve assemblies of Fig. 4-9 covers can be in conjunction with any one use in these valve inlets 110 and 115.Perhaps, also admissible other known flush valve assemblies is used in combination with these notions.
Figure 13 illustrates transition passage or sweep elbow 22, and they are from the flush valve assemblies guide edge passage 24 and the direct aquaporin 29 of water tank 12.As shown in figure 13, the radius R of sweep elbow 22 is at least 3 inches, that is, radius R must equal the diameter that narrows down of radial inlet at least.At arrival end 116 places of transition passage 22, the flush valve assemblies such as 14 will be equipped with radial bugle thing (not shown).Transition passage 22 is preferably made by ware, thus, to from flushing valve 12 to edge gateway 24 and directly the flushing water of aqueous jet passage 29 smooth mobile transition is provided.Therefore, in conjunction with the above-mentioned flush valve assemblies that has radial inlet, form the washing water quantity of one " cleaning " runner to edge gateway 24 and direct aqueous jet passage 29 supplying energies increase.
As mentioned above, the flushing water of being supplied by transition passage 22 is passed in the edge gateway 24 or is arranged in the direct aqueous jet passage 29 of toilet basin back part office.As shown in figs. 1 and 3, direct aqueous jet passage 29 preferably big relatively (15/8 " diameter), like this, flushing current of concentrating are directed in the siphon jet 30 at place, toilet basin bottom (seeing the arrow C among Fig. 3).Because of the supply of this flush toilet with one-sided injection stream, so, with the toilet designs of injection stream on the both sides with toilet basin relatively, reduced the hydraulic loss of flushing water, thus, cause washing performance and improve.In common flushing process, 2.6 premium on currency are by direct aqueous jet passage 29.
Fig. 1 and 3 illustrates flushing water flows through spiral in an asymmetrical and unidirectional unconfined supply runner edge gateway 24.In order to form the equiulbrium flow of flushing water between edge gateway 24 and direct aqueous jet passage 29, in each flush operation process, about 1.7 premium on currency are by edge gateway 24.In a preferred embodiment, the cross section at edge is approximately 11/4 " * 11/2 ".
As mentioned above, edge gateway 24 has two rhone 28a and b (all rhones as shown in figure 14).As shown in figs. 1 and 3, one of them rhone 28a is arranged on 117 places, front portion of edge gateway 24, and have one and be approximately 3 " * 5/8 " preferable size, and the second rhone 28b is arranged on rearward end 118 places of edge gateway 24, and has one and be approximately 4 " * 1 " preferable size.Flushing water passes through first and second rhone 28a and the 28b with the current discharging of two brute forces, to produce the eddy current effect of a brute force in cesspit.This eddy current effect combination causes comparatively fast and more fully removing refuse from toilet basin from the aqueous jet of direct jet channel 29 supplies and the effect of siphon vacuum, and an effective bedpan cleaning operation also is provided.
Shown in Fig. 3 and 15, edge gateway 24 also comprises a plurality of rim openings such as 26a, b, c and d.In a preferred embodiment, 25 rim openings are evenly distributed on whole peripheries of edge gateway 24.Each rim openings 26a, b, c and d have be approximately 7/32 " diameter and be approximately 11/2 " spacing.Whole peripheries of the flushing water pre-wetted toilet basin 12 by rim openings 26a, b, c and d.Although energy dissipates in the flushing water by rim openings 26a, b, c and d, this water is still contributed additional energy, forms powerful eddy current in the puddle of toilet basin, thereby removes refuse effectively and apace.
In aforesaid cleaning process, because flushing water passes through rim openings 26a, b, c and d, the periphery of bedpan obtains pre-wetted.In addition, the sidewall of toilet basin is cleaned in the powerful eddy current effect that is formed by the water by siphon jet stream 29 and rhone 28a and b effectively.
Figure 16 illustrates the bath stream that flows through edge gateway 24 in more detail, and specifically, as shown by arrow D, promptly the side direction of 24 current enters from transition passage 22 ' to edge gateway.Figure 16 also illustrates, if use the such concentrated flow of current shown in arrow E and F to discharge flushing waters in toilet basin 20 from edge gateway 24, then can realize the eddy current effect of a brute force.These two current E and F compensates one another and in toilet basin, form a brute force but the not eddy current effect of turbulent flow as yet.These two current E and F are by forming by being arranged on the flushing water that paired rhone 28a in the edge gateway 24 and 28b discharge.Figure 16 illustrates the centre that one of them rhone 28a is arranged on the edge gateway that toilet basin locates previously, and another rhone 28b is formed on the spirality end of edge gateway 24.By second and last rhone are provided at place, the end of edge gateway 24, water flows through a plurality of rim openings such as 26a, b, c and d reliably with enough amounts, and like this, whole peripheries of toilet basin obtain cleaning.Have found that, provide such as current E and two strands of such concentrated flows of F and can improve the efficient of flushing and reduce energy loss.
In addition, in the design of this kind flush toilet, the applicant has been found that it is favourable obtaining unconfined continuous current after flushing water is discharged from edge gateway 24.This purpose can be achieved by the end wall that forms the smooth gradient, for example, and back end 140 places (seeing Figure 17) of rhone 28b in the end.If wall 40 is vertical replacement gradients, then horizontal current are hindered significantly and are lost kinetic energy.
Figure 18 and 19 illustrates another preferred embodiment of the structure of the edge gateway 150 that is used for toilet assemblies of the present invention.In this embodiment, flushing water at sidewall from transition passage 22 " enter edge gateway 150.Flushing water is mobile in an asymmetric and unidirectional passage along the direction of arrow G among Figure 18 around edge gateway 150.Along this passage, first group of rim openings 152a, b and c (preferably being three quantity) are arranged on the centre in the edge gateway path that toilet locates previously, and second group of rim openings 154a, b and c are arranged on the place, end of spiral shaped edges passage.One rhone 156 also is formed in the edge gateway 150 of last opening back of second group of rim openings 154c.
(Figure 18) in this embodiment, rim openings 152a, b are relative with c with c and 154a, b big and be positioned in close.Narrow wall between all edge holes (seeing 158a, 158b) vertically provides rigidity, and reduces the distortion of current.Generally speaking, the combined area of rim openings 152a, b and c and 154a, b and c should equal the rhone 28a and the b of the correspondence among the embodiment of Fig. 3 approx.By two groups of rim openings as shown in figure 18 are provided, obtain the eddy current effect of the brute force of flushing water, make uniform water level distribute along periphery.
In the edge gateway 150 of Figure 18,, after flushing water has been finished whole edges runner of edge gateway 150, can realize unconfined continuous current by the rhone 156 in the vertical wall 160 that forms edge gateway 150.Its result, mobile by the flushing water continuation along continuous straight runs of rhone 156 dischargings, therefore, do not lose kinetic energy, if all stream strikes on the vertical wall by flushing water after the edge gateway 150, then can cause such consequence.
Figure 20 illustrates the structure of toilet basin 20.Figure 20 illustrates toilet basin 20 and has enough degree of depth and enough width, thereby has enough big puddle, like this, can not collect too many water.
In finishing the process of flushing, flushing water and waste materials enter the trap 40 that leads to sewer line by siphon jet stream 30.As shown in Figure 1, trap 40 has zone, the pool, first weir 162, and it is connected to the first acclivitous trap part 164.The length of the first trap part 164 is done minimumly, so that the normal stop water in the 162 and first trap part 164 of puddle, the pool, first weir zone are approximately 0.475 liter (seeing Figure 21).The first trap part 164 is led to second a downward-sloping trap part 166, and as shown in figure 21, it has one and is about the slope at 30 ° of angles towards bedpan.Zone, the pool, one second weir 168 is arranged on outlet side 169 places of the second trap part 166.Next trap 40 upwards climbs to one the 3rd trap part 170, and it is connected to directed and downward sagging the 4th trap part 172, the four trap parts 172 of an approximate vertical and is connected to sewer line 31.In a preferred embodiment, toilet basin 20 and trap 40 store about 1.9 premium on currency.
According to one of plurality of advantages of the present invention, trap 40 does not have reducing of cross section on its whole length.In a preferred embodiment, the diameter that the various piece of trap 40 has on its whole length reaches and is approximately 2.5 inches.Its result, diameter is less than 21/2 " refuse can by and can not stop up trap.Therefore, if any waste materials enters trap 40, then it can be by therebetween, because trap 40 does not have reducing of cross section.If any obstruction takes place in flush toilet 10 of the present invention, then stop up and will occur in the hole, can easily remove and do not need cable or Plumber's help.In addition, because the diameter of trap does not reduce, can easily pass through therebetween so remove the cable that stops up.Therefore, the design of trap herein provides the ability of remarkable removing refuse.In addition, this trapway design provides the emission index of 4.2 liters/second feeding sewer line.
Therefore, the total water amount of each circulation of this flush toilet is 5.7 liters, and wherein, 4.5 liters enter flushing water, and 1.2 liters enter into recirculation water.The amount of fresh residual water of staying in the hole after the flush operation is 0.7 liter.
Figure 22-24 illustrates another embodiment according to flush toilet of the present invention, and it reaches the flush operation that is similar to Fig. 1-3.In this embodiment, after transition passage 22a gave off, flushing water flow through edge gateway 24a (H represents with arrow) at flushing water, and flushing water flows through direct jet channel 29a (I represents with arrow) with opposite direction.Although flush water paths is pointed in this mode, find that hydraulic loss is minimum.
Figure 25 illustrates another water stream channel according to flush toilet of the present invention, wherein, current with identical direction (seeing arrow J and K) towards edge gateway 24b and direct injection circulation road 29b.In this embodiment, the part 176 of transition passage 22b is formed by plastic insertion piece.
Figure 26 and 27 illustrates, and transition passage and direct injection circulation road are formed by plastic insertion piece 180 at least in part.One first hole 182 is arranged in the plastic insertion piece 180, so that flushing water is directed in the edge gateway 24.One second hole 184 is arranged on the place, end of insert 180, so that flushing water can be directed into the bottom of bedpan.Shown in the flow path of Figure 28, be transferred to around the inlet 184 of the direct jet channel 29 of bedpan from valve inlet 110 by providing a smooth passage (plastic insertion piece 180) will spray flowing water, can reduce hydraulic loss.Compare with the current of the bigger turbulent flow that is experienced in the current approach of Figure 28,, can improve this smooth non-turbulent flowing by using plastics, rubber or some other material insert.In the ceramic flush toilet that insert is fitted in finished product, cause the convenience made and assembling more effective and with low cost.
Therefore, owing to these above-mentioned reasons, compare with existing flush toilet, designed flush toilet has reached bigger energy output, thus, provides bigger flushing water energy to remove refuse from toilet basin.In addition, flush toilet satisfies the requirement of government department, that is, forcing the minimum time of " pressing " of flush lever is 1 second, maximum water supply volume be 1.6 Jie's logical sequences (6 liters)/time.In addition, flush toilet of the present invention has improved the flow behavior and the fluid ability of flushing water, and a flush operation (seeing Figure 29) of finishing in about 2.5 second time is provided.In addition, the design of the trap of flush toilet has reduced the chance of stopping up.
