EA038749B1 - Water saving flush tank with a large section and a small section - Google Patents

Description

The invention relates to the improvement of a flush toilet cistern and is aimed at saving the consumption of water used for the purpose of cleaning.

The vast majority of cisterns produced at the present time have one integral container for storing water and flushing sewage from the toilet. With a difference in the required purpose (large and small flush), the water contained in the tank is completely overturned each time, allowing an unreasonably inappropriate consumption of clean water. At the same time, overconsumption of water is not only a loss of a private person, but, being composed of the water consumption of individual microdistricts, parts and the whole city, the volume of this water with an unjustified consumption near the vicinity of large cities forms a whole lake. Excessive water consumption causes great environmental damage to nature and economic - to society, in the form of a load on sources of clean water and its gradual depletion, purification to drinking quality, delivery, distribution of water to consumption points in cities, removal of polluted water through the sewer from the city and its thorough cleaning for return to natural circulation. This is not always possible, so the waste water is fed into the soil and pollutes underground sources.

In recent years, in many countries, they began to produce tanks with economical water consumption, where the drain fittings are designed to drain a full and small flush, the adjustment of which is made by two flush buttons.

Known device (FR 2609297) for flushing with a variable flow rate of water, designed to be installed in a cistern for flushing a toilet bowl. The device contains a stationary guide element located between the bottom and the lid of the tank. At the lower end of the guide there is an outer cap opposite the tank outlet. The device also contains a control element installed with the ability to move inside the stationary outer element. At the lower end of the control device there is a gasket that closes the outlet of the tank in the inoperative position, while the control element has at its end, opposite the gasket and located outside the tank, two drive elements that allow you to selectively move the control element at two different distances relative to the stationary guide element and therefore relative to the level of the outlet.

A number of inventions have a similar principle of the device and functioning mechanisms (RU 2493333 by priority ES P200801971, RU 2351716 by priority IT 2003A000937, RU 2420633 by priority IT M2005A002354, ES 200300300). Flush fittings in them contain a support structure, a valve body, at least one or two floats, a system for regulating the water level in the tank and, consequently, the level of the float triggering valve. The valve body is designed to slide along the support and has a valve that interacts with the seat. One float is placed movably in the container and interacts with the valve body. Thus, the reinforcement, as it were, consists of three tubular formations, with the possibility of limited movement between interconnected parts. The second pipe is connected through a linkage with a drain valve. Full or partial flushing is performed by pressing one of the two buttons on the flushing mechanism.

The disadvantages of the known inventions are their excessive complexity, where the fittings consist of 60-80 interconnected parts, a violation of the clarity of their interaction due to different adjustment measures and production tolerances, the gradual accumulation of iron oxide from water pipes in the tank leads to the fact that proper regulation of the regime of large and small virtually no flushing occurs. The vagueness of the interaction of numerous parts reduces the reliability of the use of the equipment. When checking tanks with double drains, when either of the two buttons is pressed, a complete overturning of the entire volume of the tank is often observed, which leads to an overrun of clean water. Excessive complication of the drain fittings also leads to an unjustified rise in the cost of the tank.

Known flush cistern for the toilet (patent US 3995327A, RU 2458208), which is supplied with water from both sides, where tap water is connected to one of the holes, and a pipe with waste water from a washbasin or shower installation is supplied to the other hole. Water supply adjustments are designed for different level heights. Tap water is supplied to a low level, when it is reached, it is closed by the supply valve, and then waste water is supplied to a higher level. As conceived by the authors, this saves the consumption of clean tap water.

The disadvantage of these inventions is the need for an additional tank for waste water and ensuring its higher position relative to the level of the inlet valve of the tank, while the alternating action of two valves: with clean and waste water, as described, remains doubtful. Also, in the absence of waste water, the low level of filling with tap water does not fully ensure the cleanliness of the toilet bowl flush, since the filling reaches half of the required volume.

Known drain tank (patent RU 2517833), the body of which is divided by a partition into two equal compartments, each of which is equipped with a siphon with a control rod and one drain hole. Each compartment has one inlet with a water supply valve. One compartment receives clean tap water, and the other receives waste water from a washbasin or shower unit, with the possibility of entering it into a clean compartment. With a sufficient accumulation of waste water, this compartment is mainly used, in the absence of it, a clean water supply

- 1 038749 water. The tank has a double bottom. The drain hole of the compartments is located on the upper bottom, separated from the lower by a partition, between which a free space is formed. The common drain hole is located on the second bottom of the cistern.

The disadvantage of this invention is the equal volume of compartments. With generally accepted volumes of filling a tank with 8-10 liters of water, half of its volume is slightly larger than necessary for a small flush and insufficient for a complete flush. In the presence of additional space at the bottom of the tank, the achievement of pressure is disturbed to ensure a significant flow for flushing, due to the fact that at the same time additional volume between the bottoms is first filled and the shock pressure of the initial flow decreases, and then due to a decrease in the water level, which leads to a decrease toilet bowl cleaning effect. In this case, it becomes necessary to simultaneously use both compartments, which is not clearly stipulated by the conditions for using the tank.

Known toilet tank (RU 60550), divided into two compartments of different capacities with attached two pipelines and two shut-off valves associated with floats. The toilet cistern has two drain holes at the bottom and is equipped with two siphons with control rods. The drain holes open into a hollow second bottom located above the bottom of the housing having one flush hole.

The disadvantage of the flush cistern is the presence of an additional hollow cavity at the bottom, which, when the water is drained, is filled with drain water, preventing the direct flow into the toilet, which greatly reduces the pressure of the water flow and certainly reduces the cleaning effect of flushing (for example, in a large flush). When flushing a small flush, for this reason, the effect of complete cleaning does not occur, which leads to a gradual accumulation of pollution and the settling of solid deposits into the walls of the bottom of the toilet bowl.

A variety of flush cisterns are now on sale, where the large and small flush of water is regulated by sophisticated drain valves equipped with electronic sensors. However, over time, due to contamination with iron oxides from the water pipes and salt residues, all these cisterns, when the small drain button is pressed, overturns the weight of the existing volume of water. The clarity of their action is often violated, the complex mechanisms used and the hopes for regulating the flow of water with electronic sensors do not justify their purpose. At the same time, all the time spent on the invention and then the production of complex mechanisms itself seems to have an excessive focus on the use of electronic equipment and raising the price of goods than for solving simple issues of supplying and draining water in a toilet cistern.

Checking the water flow through the toilet cistern with a separate individual meter installed for certain periods of time (monthly, for three years, with a constant number of residents) showed that the water flow through the toilet barrel often exceeds the volume of cold water used in the apartment for other needs - for washing (partial daily and complete several times during the week), cooking, washing dishes and washing clothes. Such an overrun of water for only one purpose, occurs every time with little need due to the overturning of the full volume of water. If it is necessary to use the full volume of the tank only once a day, excessive filling of the sewer is repeated up to 7-8 times. At the same time, an unjustified overrun is 65-70% of pure water consumed through the tank or more than 1/3 of the total volume consumed in a separate apartment.

The device for flushing cisterns should provide two simple functions: reliably regulate the filling of the cistern to the set volume and tightly closing the drain hole with a shut-off valve, while easily actuated by pressing the flush buttons. Therefore, the control devices for the flush cistern should be extremely simplified to use, without unnecessary complications.

The technical objective of the present invention is to create an apparatus that precisely provides that volume of water that is maximally required for a large or small flush and sufficient to maintain appropriate hygienic conditions. At the same time, the goal is to use drain fittings of known designs with a convenient and more simplified flush regulation system and industrially used feeding mechanisms with a float and a valve. The invention relates to the design of the flushing cistern itself and additional mechanisms for activating the fittings of its two separate compartments.

A flush cistern, which has the shape of a rectangular container or other shape, is divided by a partition into unequal compartments, of which most of them have 2/3, and a small part - 1/3 of the total volume of the cistern. In this case, the volume of water required for a small flush should be 3.0-3.5 liters of water, and for a large flush at least 5-6 liters. According to generally accepted standards, the water level after filling should be 40-45 mm lower from the bottom of the water inlet in the tank. Based on this provision, the dimensions of the tank are provided: length, transverse width and height. These dimensional ratios can be changed depending on the manufacturer's design approaches. However, when dividing the tank into two compartments, the required volume of flushed water must be provided: at least 3.0-3.5 liters for a small flush and 5-7.5 liters for a large flush. It should be borne in mind that the drain fittings take up 200-250 ml of volume and the required volume of water is 40-45 mm lower from the water supply hole. Therefore, the internal total volume of the tank is much larger than the actually required volume of water, and the total volume of water is 13-15 liters.

The volume of 3.0-3.5 liters of water for a small flush was determined by taking into account physiological data and numerous pilot tests of the flush and achieving an appropriate cleanliness of the toilet. According to medical data, the volume of urine per act in an adult is 250-350 ml. Urine is 97% water and 3% (by weight) from protein breakdown products (nitrogenous compounds) and salts. During the act, it mixes with the cork water contained at the bottom of the toilet, which has a volume of 750-800 ml, and is significantly diluted. At the same time, the excess volume is poured into the sewer and the same volume of 750-800 ml of liquid, already diluted by almost 1/3 of its concentration, is subject to cleaning. The volume of 3.0-3.5 liters of water turned out to be sufficient for a small flush if the flushed water has a high column, i.e. the instantaneous pressure of the water layer must initially be significant. Drainage of the same volume of water from a flat container (for example, 1/2 or 1/3 of the volume from a tank) does not achieve the desired effect. The volume of 5-7.5 water fully provides sanitary cleaning with a large flush.

The cistern is divided by a partition into two compartments: a large one from 2/3 to 6/10 of the volume and a small one from 1/3 to 4/10 of the volume, has two holes on both sides for installing a filler tube with a valve and floats, two release buttons , two fittings for regulating the flush and two holes for draining water into the toilet. Tap water is supplied to the upper side opening on one side. However, to save space, it is necessary to reposition the nozzle and float. The filling connection with the valve and the float should be installed in a perpendicular position relative to the main channel of the tube connected to the water supply hose, and its free end has a screw connection. A filler is also installed in the opening of the second compartment, which has an identical design, similar to the first. Both devices are connected to each other through holes on the partition with a copper or reinforced plastic tube. In this case, the outer end of the water supply tube of the second compartment is closed with a plug. However, at the request of the owner, a separate hose can be connected to the second supply valve, and the pipe connecting the two compartments can be removed or left for reliable water supply to both compartments.

In recent years, water supply to the tank through an opening located at the bottom has become widespread. When using the mechanisms of this water supply device, it is necessary to make holes in the bottom of the tank for each compartment. In this case, the holes should be closer to the outer corners of the tank in order to save the placement of these devices.

The device of a tank with two unequal sections, its structural changes, shapes, structure of parts and connection schemes of mechanisms that ensure the normal functioning of the tank are shown in the following drawings:

fig. 1 - flush cistern with large and small sections;

The appendix contains continuous numbering of parts.

The division of the body (Fig. 1.1) of the tank by the partition (2) into two unequal compartments (3, 4) and the need to achieve significant pressure of the water jet for flushing requires changes in the design of the tank. At the same time, the partition has a height lower by 1-1.5 cm than the wall of the tank itself, for intensive air passage with the alternating use of two compartments. The bottom (5) of the tank is raised by 5.5-6.0 cm by the continuation of the tank wall into the apron rack (6), which is the support of the tank when it is connected to the toilet. The end edges of the rack are somewhat thickened in the inner part for stability and reinforcement against breakage in case of an accidental impact. The back wall of the apron at the level of the middle of the tank can have an opening (14) 12-13 cm wide for installing a rubber seal to the tank tube and the toilet bowl opening. When water is supplied to the tank from the bottom on the back wall of the apron closer to the side edges, two holes (not shown) are also made for conducting the branch pipes. At the bottom of the tank, along the median line, there are two flush openings (9, 10), located at a distance of 1.8-2 cm from the wall of the partition.

The flush openings at the bottom are bordered by a funnel receiving bowl slightly larger than the diameter of the opening, and a circular protrusion is formed to the thickness of the bottom of the tank. The small compartment funnel drain (11) under the bottom of the tank makes a bend towards the middle of the tank. In this case, the upper wall of the branch pipe is drained from the bottom of the tank. The horizontal part of the branch pipe has a flattened shape in height of 2.5-3 cm and widened by about 5-6 cm in width. The drain funnel (9) of the large compartment passes into the branch pipe (12), which is also slightly displaced towards the middle of the tank. The pipes of the funnels of the small and large compartments in the middle of the tank bottom form a common flush pipe (13). Its length is 1.5-2.0 cm, in the lower edge it has an annular thickening of 2.0-2.5 mm for tight fastening of the rubber sleeve. The outer diameter of the flush pipe is 2.5-3.5 mm less than the diameter of the toilet bowl opening.

In the invented design of the flushing cistern, two drain fittings are used with a one-stage water drainage with the most simplified but reliable system of mechanisms for draining water from the cistern.

Suitable for these purposes are inventions: patents: GB 2397634 A, RU 150780, RU 153014, RU 153028 RU 2271420, RU 2158336. In particular, the mass production of drain fittings is well established (according to patent RU 150780, RU 153028), which has been tested in practice with great reliability. In this case, the flush fitting of the flushing cistern has the following device: a saddle, a shut-off element, an overflow unit with a vertical double-post support, a push-button flush mechanism with a pusher, a shut-off element lifting mechanism made in the form of a double-arm lever device hinged on a vertical double-post support, the large arm of which is hinged interacts by means of a thrust with the bracket of the locking element, and the small shoulder - with the pusher of the push-button flush mechanism. Between the posts of the vertical two-post support, coaxially to the vertical axis of the overflow unit, the first (large) horizontal frame is rigidly fixed, inside which there is a support sleeve for the push-button flush mechanism. For the purposes of our design of a tank with two compartments with different volumes: large from 2/3 to 6/10 of the volume and small from 1/3 to 4/10 of the volume, the most suitable were the drain fittings AB 68.54.U1.3 in accordance with GOST 21485-94 ... It is possible to use fittings with some changes in individual units.

The fittings of the two compartments are installed close to the bulkhead of the tank. It is more rational if the edges of the drain holes at the bottom of the tank are 20-21 mm from the wall of the partition, along the median longitudinal line of the tank. The diameter of the flush hole at the bottom of the tank is made in accordance with the width of the lower base of the reinforcement.

Functionally, the cistern can be used in two versions. In the first variant, two compartments are used independently, through the corresponding release buttons: a small compartment for a small flush, a large one for producing a large flush. The drain fittings operate independently. When a large volume of water needs to be flushed, both buttons are pressed simultaneously with two fingers, which reliably ensures a complete cleaning of the toilet bowl.

In the second variant, the reinforcement of a large volume is connected with the help of a rocker thrown over the opening of the partition with a drain mechanism for the reinforcement of the small compartment. In this version, it is possible to independently drain the water of the small compartment by pressing the small release button, and if it is necessary to release a large volume of water, the button of the large compartment is pressed, which simultaneously drives the mechanisms for releasing the valves of the large and small compartment.

In the invented design of the flush cistern, the simultaneous discharge of water from the large and small compartments is carried out using a rocker arm (Fig. 3) connecting the two compartments. For the manufacture of the rocker, a plate with a certain stiffness is used, made of a copper alloy or galvanized iron, 130-135 mm long, 20-22 mm wide and 1.5-2.0 mm thick (Fig. 2). At one end, the plate has a narrowing 9-10 mm wide and 10-12 mm long, and the other end of the plate is narrowed to 16-17 mm by a length of 55-58 mm. This end is 30-35 mm long, sawn into two branches, forming the forks of the rocker arm (Fig. 3; 18). The width of the branches is 3-4 mm, between which there is a free gap of 7-8 mm. In this case, the wide straight part of the plate (15) has a length of 55-60 mm. In the expanded part of the plate, 2-3 mm from the bent nipple, make a hole with a diameter of 2 mm (20) and from it, at a distance of 50-53 mm, make another hole (21) 2-2.5 mm wide and 3-4 mm long longitudinal line. A rocker arm with the required configuration is made from this blank, which has different tapering shapes at its two ends.

The first end of the plate is bent vertically upward, forming a nipple (Fig. 3; 19) 10-12 mm long. The vertical nipple of the plate is designed to be inserted into the slot of the descent vehicle pedal of the armature of a large compartment. At the second end of the constriction, first bend the part down (16) at an angle of 5558 °. The bottom fold is 25-27 mm long. And then the plate from the place of its bifurcation is bent back upward in a smooth arc, gradually bringing the angle up to 75 ° from the horizontal, forming a hooked grip with a fork. All the details of the rocker arm: shape, tapering of the ends, fork, holes and bends are made by stamping (Fig. 2). The dimensional data of the workpiece and individual parts of the rocker arm depends on the size of the tank: height, width and length, respectively, they must be adjusted by repeated testing.

The rocker arm is the link that drives the escapement linkages of both compartments. For the normal and coaxial functioning of the operation of the two compartments of the cistern, the parameters of movement and the load on the rocker arms must be clearly regulated. Therefore, it is necessary to make a number of changes in the partition between the two sections and in individual parts of the drain fittings and the rocker arm mountings.

In the bulkhead of the tank between the compartments at the transition point of the rocker arm, an opening should be made 2.02.5 mm below the level of the foot of the drain valve pedal, the fittings of the large compartment. The opening width is 1.0-1.5 mm wider than the rocker plate. A saddle is threaded onto the partition (Fig. 4; 22), which has a hairpin (23) or a pin 2.0-2.5 mm thick, respectively, fixed in its middle. The saddle with a pin is made of stainless steel or plastic. The lower edge of the saddle is bent inward into the hook (24) by 1.0-1.5 mm, which are fixed in a special recess on the partition made at the appropriate level from the edge of the opening.

The pedal of the pusher of the drain valve of the fittings is shaped like a shoe with an elongated toe (Fig. 5; 28), which serves to actuate the water release lever. To attach the rocker arm to the drain fittings of the large compartment, the pedal sole on the other side (29) must be extended to the rear by 5-6 mm. A hole with a diameter of 2-2.5 mm is drilled in it. In a small compartment, the thickened part of the traction arm crossbar should be expanded by 1-2 mm for reliable support of the rocker fork, while the place where the traction hook engages with the water trigger lever should be narrowed. The thrust immediately after engaging the hook for 40-50 mm in length should be done in a smoothly rounded shape (33) so that when the large flush mechanisms are turned on, it does not interfere with the action of the rocker fork.

For the coaxial functioning of the drains of the two compartments, the drain valves of the large compartment (Fig. 5) are installed with the crossbars of the water drainage thrust lever towards partitions (Fig. 5). At the same time, in the large compartment, the valve drain pedal with a rear extension (29) faces the baffle and serves to attach the rocker arm with a short vertical nipple (19).

The connection and actuation by means of a rocker arm of the escapement mechanisms of the large and small compartments are carried out as follows. The rocker arm (Fig. 3) is inserted through the middle hole (21) onto the pin (Fig. 4; 23) and installed on the saddle (22) of the cistern partition. Then the perpendicularly bent toe of the rocker arm (19) is inserted into the slot of the pedal (29) of the drain valve of the drain fittings of the large compartment. A two-fork hairpin with a support head (not shown) is threaded onto the holes (20) of the rocker arm plate and the rear flap of the pedal, the branches of the hairpin are unbent to the side, fixing the rocker to the pedal. On the end fork of the rocker arm (17, 18), a large arm of the lever (31) of the small drain trigger is mounted. In this case, the forks of the rocker arms rest on the thickenings of the crossbar of the lever, and in the middle between the branches of the fork (18) there is a long rod (33) of the drain valve of the small compartment. Pressing the large flush button activates the drainage levers of both compartments. The large drain button pedal (28) presses on the short arm of the lever (30) and raises the rod (33) of the drain valve of the large compartment, while the rear pedal (29) simultaneously presses the rocker arm (15) in the large compartment on the arm, and its other end bent fork (17, 18), lifts the lever with the rod (33) of the drain valve of the small compartment fittings. There is a simultaneous drainage of water from two compartments. When the small flush button is pressed, the small flush armature acts independently, without activating the large flush trigger mechanisms.

The purpose of the flush cisterns with two sections with separate or simultaneous drainage of water must be determined based on the convenience of their use and the load of use. In places of mass visits of people with different levels of culture of using toilets (airports, railway stations, cinemas, hypermarkets, restaurants and other catering places), tanks should be installed with separate drains of water from two departments, and at home, tanks are coaxially connected by means of a rocker arm for simultaneous drainage of water from both departments.

For the convenience of flushing the large and small sections of the tank, it is necessary to introduce different designations in the shapes of the water flush buttons. The small drain button should be made in the form of a green sheet with a corrugated surface in accordance with the vein patterns, the large drain button should be made in the form of a brown or yellow light with a smooth surface. Reminiscent signs are known to be more effective in guiding people's actions.

Fastening of the reinforcement to the bottom of the tank body is carried out using a plate (Fig. 7) made of stainless steel, which has a trapezoidal shape. In the middle of the plate there is a large round opening (39) with four slots (40); closer to the edge of the elongated part of the plate, holes (41) are made for attaching it to the bottom of the tank. The plate is inserted through the slots into the vertical rib-posts of the reinforcement (Fig. 6. 37) and installed on its horizontal base (35). The lower tubular part of the base of the reinforcement (36) has a smooth shape, somewhat smaller in diameter (by 3-4 mm) than the opening in the bottom of the tank. The installation of fittings to the bottom of the tank and prevention of water leakage from the joints of the fittings to the bottom of the tank is provided by a special rubber seal (Fig. 8), which has an annular groove (42) in the middle on the outside, and on the top (43) and bottom (44) parts - annular thickened sides. The height of the groove is equal to the thickness of the wall of the opening of the bottom of the tank, and the thickness of the upper flange is 5-6 mm, the lower 3-4 mm. With an annular groove, the seal is inserted into the walls of the hole in the bottom of the tank, and the drain pipe of the fittings is installed in the opening of the rubber seal. The apparatus is fixed with a metal plate (Fig. 7), put on the bases of the reinforcement (Fig. 6; 35) with two long bolts through the holes of the plate (41) and the holes in the bottom of the tank (not indicated) and tightened with nuts. Preliminarily, rubber conical seals (not shown) are put on the bolts between the metal plate and the bottom of the tank.

The connection of the common flush pipe of the cistern with the toilet bowl opening is carried out using a rubber sealing funnel (Fig. 9), in which the upper part is expanded (45), in the middle it has an annular petal cuff (46), and in the lower part - a conical narrowing (47). In this case, the upper end of the rubber seal is put on the annular thickening of the flushing pipe and is pulled together from the outside by an annular bracket. Then the tank is installed on the upper platform of the toilet, making sure that the direction of the rubber seal and the bolts to the holes in the upper part of the toilet is correct. At

- 5 038749 In this case, the annular collar rests against the recess around the drain hole, and the lower cone-shaped narrowing of the rubber fits snugly against the opening of the toilet bowl. The cistern body is attached to the upper platform of the toilet bowl through its holes with protruding reinforcement bolts and secured with plastic nuts.

The use of a flush cistern with separate sections for large and small sanitary cleaning of the toilet saves 1/3 of the clean water used for the domestic needs of cities and megalopolises, and will also bring tremendous environmental benefits, does not deplete sources of clean water, prevents massive environmental pollution and harmful groundwater leftovers.
