Invention field

The present invention relates generally to a kind of flush toilet stench trap resealing device of selectively water being guided to water tank overflow pipe from heavy water shutoff flexible pipe.In addition, the present invention also relates generally to the flushing device for water closet with water-saving performance, relate in particular to the flushing device for water closet of the double rinse mechanism with two kinds of effects of length flushing, this double rinse mechanism uses single handle and single flushing valve to drive a short time or long two kinds of flushings.

Background of invention

For solid feces being provided a completely or long flush cycle and liquid discharges is only provided the flush cycle of a short time or part, so that using water wisely when not needing to use complete flush cycle, the flush toilet mechanism that has opened up multiple double rinse for many years.The protection of natural resource such as water is very important.It is desirable using more a spot of water to wash excremental flush toilet.

The feature of the double rinse mechanism of prior art is total is included into two classes.First kind device comprises and adopts two independently double rinse mechanisms of flushing valve.The flushing valve that is used for washing fully is lower than the position of the flushing valve that is used for the short time flush cycle in the position of water tank.The example of structure of this class double rinse mechanism can be at Blang's No.1, and 960,864 United States Patent (USP)s are seen.Blang's patent has been described a kind of device with flush toilet of two flushing valves, and wherein, the release lever arm of two different lengths has a common fulcrum, when handle clockwise or when rotating counterclockwise, two release lever arm are rotated around fulcrum independently.

The second class double rinse mechanism has been characterised in that two independently handles, and one is used for long-time flushing, and another is used for the short time flushing.Driving different handles can make the single flushing valve in the water tank rise to different height.For example, the No.4 of Hani, 881,279 United States Patent (USP)s have described a kind of dual-handle system, and wherein, the rotation of first handle forms the flushing fully of a routine, and the rotation of second handle makes flushing valve only rise a part to drive a short time or partial flushing.The patent of Hani has used a kind of system of complexity to carry out the short time flush cycle.

Leicester's N0.2,001,390 United States Patent (USP) use a clutch apparatus on the bar of flushing valve, so that flushing valve is on the position of the part that only rises.

Most of users get used to the flush toilet of single handle, and most of flush toilet is all used the parts of single flushing valve as the toilet flush structure.Therefore, need a kind of improved double rinse device that is used for toilet flush, the single flushing valve of the available single handle drives of this device is to carry out a short time flush cycle or long-time flush cycle.People also need a kind of can being used for that traditional toilet flush is carried out improved double rinse mechanism.

In toilet flush, also have a kind of situation of waste water resource to occur in heavily aspect the water shutoff flexible pipe.After the flush toilet flushing, water tank must refill clear water.In addition, be necessary for flush toilet bottom again between the flood period or trapway provides some water at water tank, to guarantee that trapway is heavily sealed.In traditional flush toilet, heavily the water shutoff flexible pipe extends from the inlet control device of water tank, and during water tank water filling again whole water is guided to water tank overflow pipe (bleed off pipe leads to flush toilet bottom or trapway).Because trapway heavily is honored as a queen, unnecessary water will flow to gutter, therefore causes the waste of water.

In addition, owing to need two kinds of different water flooding regimes again, the double rinse device in the toilet flush makes the current operation complicated.Because have the flush toilet of double rinse, the longer duration of the again water filling of the duration of the water injection cycle again after the long-time flushing after than the short time flushing is used for guaranteeing that generally the volume of the water of the reseal water bend when washing in the short time is big at the volume of the heavily water shutoff of the trapway that heavily seals the flush toilet bottom after the long-time flushing.Heavily water shutoff was under-supply for trap when this just might cause the short time to be washed, thereby was unfavorable for keeping health.Yet on the other hand, between long-time flush period, heavily the water shutoff water filling is excessive for trap, thereby slatterns the water that can be used better originally, for example, and in order to wash solid feces and to be used to refill water tank.

The heavy seal structure of the water of prior art has been noticed and has heavily been sealed the problem that flexible pipe is wasted water, and the complete gratifying method of attempting toing many or too much for use solves it.For example, the No.5 of La Zhaer, 341,520 United States Patent (USP) has been described the flushing device for water closet of a dual capacity, wherein, the overhang bracket that heavily seals flexible pipe is on a movable slabbed construction, and when the water filling of flush toilet bottom again, described movable slabbed construction makes selectively again that the water filling flexible pipe flatly leaves bleed off pipe.The No.4 of the hole pareira base of a fruit, 910,812 United States Patent (USP)s have described the flushing toilet system of a complexity, and wherein, in the part-time of flushing cycle, bleed off pipe leaves the outflow path of the water that heavily seals flexible pipe around axle.

Yet up to the present, also there is not a kind of people accepts, reliably and simply heavy water shutoff hose that can allow, this assembly makes heavily the water shutoff flexible pipe that water is guided in the water tank in the part stage of flush cycle, after this, allow heavily the water shutoff flexible pipe that water is guided to bleed off pipe with reseal water bend, thereby the water of equivalent is provided during long-time and short time flush cycle.

Therefore, hope has a kind of improved heavy water shutoff hose, this assembly can reduce the consumption of unnecessary water and can assist the injection of the water of toilet flush, to carry out efficient than higher fill cycle again.In addition, wish to have the heavy sealing assembly of a kind of trapway, no matter long flush cycle of this assembly or short flush cycle can both be delivered to trapway to the heavily water shutoff of an amount of volume, and directly guiding in the water tank, thereby the unnecessary current of the envelope flexible pipe that can be used to conduct oneself with dignity by the steering handle water that changes flexible pipe water.

Brief summary of the invention

Generally, the present invention is to provide a kind of double rinse device that is used for toilet flush, this device has a single flushing valve that actuating arm drove by swaying to carry out short or two kinds of long flush cycle.This double rinse device comprises that one is rotatably supported in the cam on the toilet flush, and the position is near actuating arm.When cam when first direction rotates, cam rotates to grow flush cycle actuating arm.When cam when second direction is rotated, cam rotates to lack flush cycle actuating arm.The double rinse device comprises that also one can be with respect to the bar of actuating arm rotation between the primary importance and the second place, bar does not stop actuating arm when primary importance, on the second place, on cam bar when second direction is rotated stops that one scheduled time of actuating arm is with the position that actuating arm is remained on the part that rises.One float is connected with bar to determine this scheduled time.When cam when second direction is rotated, float makes bar forward the second place to around axle.

In a preferred embodiment, the double rinse device comprises a single handle, and it can be selectively at first direction or second direction rotating cam.

Another aspect of the present invention provides the heavy sealing assembly of a trapway.One annular float is peripheral unsteady at the tube wall of bleed off pipe along with the variation of the water level in the water tank in toilet flush.Heavily an overhang bracket of water shutoff flexible pipe is guided to bleed off pipe or water tank to water selectively according to the height of float on float.

Therefore, one of purpose of the present invention provides a kind of improved flushing device for water closet with water-saving function.

Two of purpose of the present invention provides a kind of be used for water tank, improved double rinse device, and this device only needs just can carry out short or two kinds of long flush cycle by the single flushing valve of single handle drives.

The detailed description of preferred embodiment

At first consult Fig. 1 and 2, the flush toilet that total usefulness 20 is represented among the figure has a flush toilet body 21 and a toilet flush 22.Toilet flush 22 comprises a tank lid 23 movably.Water tank 22 also comprises double rinse mechanism and heavy sealing assembly of trapway that total usefulness 50 is represented that two total usefulness 30 constructed according to the invention are represented.

In water tank, be provided with a water enter Control Component 70 with after finishing in flushing control clear water refill water tank 22.Again between the flood period, some clear water offer one and heavily seal flexible pipe 52 at water tank.Water tank 22 comprises that one leads to flush toilet body 21 or directly leads to the bleed off pipe 24 of the trapway below the flush toilet.Water tank 22 also comprises the flushing valve that a total usefulness 60 is represented, in the time of flush toilet, this flushing valve provides a water channel for water flows to flush toilet body 21 from water tank 22.Flushing valve 60 comprises that a valve seat 62 and can open and close the rotating flushing valve valve (valve gap) 64 of valve.

The structure of double rinse mechanism 30 is described further combined with Fig. 3 and 4 now.Also will describe in detail below, double rinse mechanism 30 is driven by a handle 32 in water tank 22 outsides, this handle 32 can rotate to carry out a flush cycle long period or complete in the counter clockwise direction shown in the arrow A, also can rotate to carry out a flush cycle short time or part at the clockwise direction shown in the arrow B.

Double rinse mechanism 30 comprises that one has the L shaped drive rod that pivots or the arm 34 of the first arm 35 and second arm 36.In a preferred embodiment, the first arm 35 to the second arms 36 are long.The free end 35a of the arm 35 of drive rod 34 links to each other with the valve gap 64 of flushing valve 60 by a chain or other soft connectors 66.The free end 35a of the first arm 35 can comprise that several are along the through hole 33 that is provided with at interval on it, so that chain 66 is tied up on the desired position.Connecting another flushing valve float 67 on the chain 66, opening to keep valve gap 64 during the long flush cycle that will describe in detail below.

Double rinse mechanism 30 comprises that also one is the short time rinse bar 80 of the L shaped bell crank lever form that can pivot.Although can be with other fasteners but the most handy wing nut 87 removably is connected in short cyclic flusher bar 80 to a float 84 that is used for partial flushing by a float lever 86.

As we can see from the figure, double rinse mechanism 30 preferably is installed on the antetheca of water tank 22.In addition, whether handle 32 makes things convenient for and consideration can not conflict mutually with the existing structure of prior art water tank when double rinse mechanism 30 is installed owing to will consider to contact, so the definite position of its installation can change as the case may be.In an embodiment as described in Figure 3, form a through hole at the antetheca of toilet flush 22 and water tank wall is clipped in a back plate 38 and a nut or other and covers between the orifice plate 40 and double rinse mechanism 30 is installed on the antetheca.Back plate 38 comprises a through hole 38a, and an axle 31 that rotates with handle 32 passes this through hole.Yet also imagination back plate 38 can be used as the part of toilet flush inwall.

Handle 32 is connected in double rinse mechanism 30 by axle 31.With a screw or like parts one cam 42 with asymmetric first cam end 43 and second cam end 44 is fixed in axle 31, so that rotate therewith.Cam 42 can be configured to other shape, and Kidney bean shape for example is as long as to contact and mention drive rod 34 when rotating counterclockwise just passable when cam 42 is clockwise.Certainly, what should give attention is, other forms that drive single handle are different rotary amount etc. for example, also can be used for finishing different flush cycle.

In one embodiment, drive rod 34 is being supported by a pin 38b who stretches from back plate 38 rotatably about an axis.This mounting structure make drive rod 34 can one be arranged essentially parallel to the back plate 38 the plane in rotate.The arm 35 of

drive rod

34 and 36 can be configured to be rigidly fixed to together, and perhaps drive rod 34 also can be the parts of an integral body.In addition, arm 35 also can be that a global facility can comprise that maybe one makes 36 motions of relative in the horizontal direction second arm of the first arm 35 so that can be used for the joint 78 of different structure.One pin 79, screw or similarity piece are installed as the part of joint 78, with two partial fixings of drive rod 34 together.

When it should be noted that free end 35a when arm 35 is at least basically above flushing valve valve gap 64, the work of double rinse of the present invention mechanism is best.Below also will be than describing in greater detail, when drive rod 34 was raised, flushing valve valve gap 64 lifted off a seat 62.So, if the free end 35a of arm 35 above flushing valve valve gap 64, flushing can be carried out with effective and efficient manner.Because joint 78 is provided, the first arm 35 can solderless wrapped connections 78 rotates, with the free end with arm 35 be positioned at needed position with avoid with water tank in miscellaneous part clash.

Short time rinse bar 80 adopts the joint 81 of pin, screw or similarity piece 85 by one and is connected in back plate 38 rotationally, and be with 34 one-tenth vertical directions of drive rod on.Short time rinse bar 80 comprises two legs 82 and 83.Leg 83 is connected on the float lever 86.A part of flushing float 84 is connected in float lever 86 slidably, so that adapt to existing conventional toilet water tank and can regulate and control the length of short time flush cycle.Because can manually change the position of partial flushing float 84 along float lever 86, double rinse mechanism just can use in the flush toilet of prior art.

In addition, particularly shown in Fig. 4 and 9, float lever 86 can be installed on the leg 83 with multiple orientation.Leg 83 has a star through hole 87, makes the end 86a of float lever 86 can insert wherein different positions.The end 86a of float lever 86 can comprise suitable wing 86b and the 86c that cooperates with hole 87.Behind the location, float lever is fixed on the position with a wing nut 87a.

As described in below inciting somebody to action, on water tank wall, be provided with a retainer 90 to stop the inordinate rotation of cam 75.

Fig. 3 and 5 shows the situation before the full time flushing of water tank, because partial flushing float 84 rises with the water level in the water tank, the leg 82 of short time rinse bar 80 leans against on second arm 36 of drive rod 34.

Working condition when describing double rinse of the present invention mechanism and drive a long-time or complete flush cycle now in conjunction with Fig. 5-7.

Rotate counterclockwise handle 32 with the direction of arrow A in front and just can start long-time or complete flush cycle.This rotation of handle 32 is and then rotated axle 31, and axle 31 makes cam 42 rotate at equidirectional again.This rotation makes the long cam end 43 of cam 42 contact with the upper part of second arm 36 of drive rod 34, thereby rises the first arm 35, and arm 35 makes progress zip strip 66 again to rise the valve gap 64 of flushing valve.Float 67 correspondingly is pulled upwardly the water surface (Fig. 6) that is reducing to water W.35 limiting altitudes that can arrive of drive rod 34 rotary angles and arm are subjected to the restriction of retainer 90 on the wall.Retainer 90 among the figure is curved, but this does not have a limiting sense as just example.Retainer 90 on the wall can be installed in the back plate 38 on or with the back plate 38 integrally formed.

When handle 32 when the direction of arrow A (as shown in Figure 1) rotates counterclockwise, the lower limb of retainer 90 contacts on the short cam end 44 of cam 42 and the wall, thereby stops cam 42 and handle 32 further to rotate.At this for a long time or under the flushing situation fully, flushing valve valve gap 64 moves on to it and opened fully or buoyant position, make that water is discharged in the flush toilet body with flush toilet in the water tank.When the water surface in the water tank falls, float 67 also descend (but remaining on the water surface).Drive rod 34 also drops to its home position.When a precalculated position is fallen in the underwater, flushing valve valve gap 64 to be closing with the same mode of prior art and heavily to seal valve seat 62, thereby stops complete flush cycle.Then, water tank begins water filling again.

As shown in Figure 3, under the situation before the flushing of water tank in fills with water, leg 82 is pressed in arm 36 1 sides of drive rod 34 owing to the buoyancy of partial flushing float 84.As shown in Figure 7, when long-time flush cycle begins,, as if after the water tank emptying, can stop drive rod 34 to get back to its origin-location because short time rinse bar 80 is rotated towards handle 32 with the direction of arrow C at first.Yet, should be understood that, that after flush cycle begins for a long time when the water in the water tank flow in the flush toilet by flushing valve, the water surface in the water tank began to fall.The decline of water is also fallen partial flushing float 84, thereby thereby rotating short time rinse bar 80 before flushing valve valve gap 64 covers and heavily seals valve seat 62 makes it to rotate the rotation path of the arm 36 that leaves drive rod 34 towards leaving handle 32 directions.So, can see that the existence of short time rinse bar 80 can not influence long-time or complete flush cycle.

Consult Fig. 8 to 9 now, they show during the short time flush cycle, the working condition of double rinse of the present invention mechanism.Clockwise direction (as shown in Figure 1) turning handle 32 in arrow B just can actuating section or short time flush cycle.Handle 32 rotation turning cylinders 31, axle 31 makes the short cam end 44 of cam 42 contact with the lower part of second arm 36 of drive rod 34, is the second low predetermined altitude thereby make the first arm 35 of drive rod 34 rise to the predetermined altitude that a ratio washes for a long time.

At this moment, amount of spin and highly also be subjected to the restriction of the retainer 90 on the wall.In the clockwise direction, the top of retainer 90 contacts on cam end 43 and the wall, to stop the inordinate rotation of drive rod 34.Therefore, flushing valve valve gap 64 can not break away from valve seat 62 and rises to the height that long-time flush cycle duration of work is fully risen.In addition, because float 67 is raised inadequately, can not be raised to the water surface by (float) on the buoyancy, flushing valve valve gap 64 is just drawn high by chain 66 and opens not is to be that buoyancy by float draws high and opens resembling in complete flush cycle.

In case drive rod 34 is raised, the buoyancy of partial flushing float 84 makes the leg 82 of short time rinse bar 80 rotate towards handle 32, and is pressed against the surface of cam 42 as shown in Figure 9.When release handle 32, the inner surface 36a that the leg 82 of short time rinse bar 80 will contact second arm 36 of drive rod 34 moves downward to stop further, the first arm 35 of drive rod 34 is remained on the position of a rising, make flushing valve valve gap 64 remain on a position that partially opens, allow among water flows to flush toilet from water tank.

Yet after the short time, flush cycle began, the water surface began to fall.When the water surface descended, partial flushing float 84 reduced with the water surface in the water tank.On a predetermined water surface, the partial flushing float 84 one section enough distance that descended makes short time rinse bar 80 toward back rotation, therefore, leg 82 breaks away from the arm 36 of drive rod 34, thereby permission drive rod 34 rotates and descends, make flushing valve valve gap 64 closures and heavily seal, thus dwell section or short time flush cycle.

When water injected water tank in the mode of prior art again, flushing float 84 rose in water tank, and the leg 82 of short time rinse bar 80 rotates around it the axle rotation and resets, for flushing is next time prepared.

Owing to provide one to allow the user just can drive single flushing valve to start the double rinse mechanism of flush cycle wholly or in part, thereby provide an improved double rinse mechanism that can economize on water by the rotation direction of selecting single handle.Rotate single handle in the counterclockwise direction and can drive a flush cycle completely.This rotation makes cam contact actuating arm, thereby makes the flushing valve valve gap leave its valve seat and rise.The ascending motion of actuating arm is subjected to the restriction of a retainer.

At the partial flushing circulation time, handle is to rotate in the clockwise direction.This rotation makes cam contact with drive rod, but makes smaller amplitude of drive rod rising.Similarly, the ascending motion of actuating arm also is subjected to the restriction of retainer.Release handle makes the short time rinse bar temporarily keep driving under the situation that part rises, thereby flushing valve is remained on a position of opening, and water is flow in the flush toilet from water tank.When the water surface in the water tank descended, the partial flushing float also fell to making short time rinse bar and drive rod to break away from.Make actuating arm get back to its flushing position before thus, valve gap comes back on the valve seat of flushing valve.Along with water tank water filling again, the partial flushing float rises, thereby rotates the short time rinse bar and contact with drive rod, for flush cycle is next time prepared.

Consult Figure 10 to 14 now, they show the heavy sealing assembly 50 of trapway.Assembly 50 comprises a heavy water shutoff flexible pipe 52, and this flexible pipe 52 has one to be connected in the free end 52a that heavily seals float 54.In preferred embodiment, heavily seal flexible pipe 52 and be connected in by a chuck 53 or like parts and heavily seal float 54.Heavily seal float 54 preferably in the form of a ring, and supported slidably so that can be peripheral unsteady at the tube wall of bleed off pipe 24.Bleed off pipe 24 can comprise that also prevention heavily seals the latch 55 (Figure 10) that float 54 breaks away from bleed off pipes 24.In addition, bleed off pipe 24 comprises a splashproof spare 56 (Figure 10) with the flowing of the current of assisting guiding and coming out from flexible pipe 52, and anti-sealing splashes.

Consult Figure 11 to 14 now, they show the working condition of the heavy sealing assembly 50 of trapway of the present invention.Before flushing, when water tank was full, float 54 was in uppermost position shown in Figure 11.In this position, free end 52a is in the position of water being introduced bleed off pipe 54.Yet,, under the situation before the flushing, do not have water to flow because the water intaking valve of control water is closed.

After long-time or short time flush cycle begin,, heavily seal float and begin drawdown with water tank because the water in the water tank has been discharged among the flush toilet.Distance X shown in Figure 11 is heavily sealed float 54 drops during being illustrated in the short time flush cycle, and distance Y is represented drop during the long-time flush cycle.In case float 54 drops to height shown in Figure 12, heavily seal flexible pipe 52 below bleed off pipe 24 edges, the water that heavily seals flexible pipe will flow in the water tank and go.

When water tank again during water filling, heavily seals float and begins to rise behind valve closing.Water in the flexible pipe 52 will continue to flow in the water tank, until float arrives till the position shown in Figure 13, so far water begins to flow in the bleed off pipe.It is to be noted that especially after arbitrary flush cycle, the position when heavily water shutoff begins to change direction and flows to bleed off pipe all is identical, thereby the quantity of heavily water shutoff of having guaranteed to be used for the pent-up water bend is identical.When water continues to rise, heavily seal the top that flexible pipe 52 returns bleed off pipe 24, water is flowed directly in the bleed off pipe 24 as shown in figure 14.Current advance bleed off pipe till water tank is full of.

The heavy sealing assembly of trapway of the present invention makes the excessive water of the envelope flexible pipe of conducting oneself with dignity be used to refill water tank.No matter be long flushing or short flush cycle in addition, the water yield of delivering to trapway by bleed off pipe is equal substantially.

By providing a kind of its heavy envelope flexible pipe to be installed in one along the heavy sealing assembly of trapway on the peripheral float that floats of bleed off pipe tube wall, the invention provides a kind of improved double rinse flushing toilet system, this system provided is used to seal the quantity of the heavily water shutoff of flush toilet trapway, no matter be long or short flush cycle all is identical.It is by the trapway rinsing module that provides a kind of its water to be controlled by a position of heavily sealing float, and this is located according to the water surface in water tank and heavily seal float, thereby a kind of improved heavy sealing assembly is provided.

Thereby as can be seen, purpose recited above and the description by the front, conspicuous other purposes can both realize effectively, because under the situation that does not break away from essence spirit of the present invention and scope, making some change at said structure, therefore, illustrated all the elements just are used for illustrating the present invention in above description or the accompanying drawing, and the present invention is not limited to the content shown in above description and the accompanying drawing.

Should be understood that, that also following claim intends covering the present invention described here all total and concrete features, and the statement about scope of the present invention, can be described as all always all are included within its protection domain with concrete feature.
