EA014601B1 - Flush device with dual volume of water flush - Google Patents

Abstract

In a flush device (A) with dual volume of water flush, when a small volume flush is done from a tank, while the water level reaches the position of a lower level of a small volume hollow float (12), a gravity force of the small volume hollow float (12) is increased by comparison with the buoyancy force of water, in order to effectively transmit the gravity force to an adjustment rod (11), and then to a small volume float (10) for separating the small volume float (10) from an overflow tube (4) there is a reservoir (73) filled with water at the upper side of the small volume hollow float (12). Also in the flush device (A) arms (47, 56) of the floats, holding the pins (40, 50) of the large and small volume floats, are placed into holes (87) for the floats by fitting together such that the pins (40) of the large volume float are near to the small volume float (10) and the pins (50) of the small volume float are near to a large volume float (9) in order to provide floats (9, 10) to lean easier to the overflow tube (4).

Description

This invention relates to a draining device intended for a toilet tank, by means of which two different volumes of water can be drained: a controlled small volume and a constant large volume, and to improvements made in the construction of such a draining device.

The decrease in natural resources has resulted in the need to reduce the amount of water used in latrines. Drainers used to fulfill this requirement for toilet tanks in a toilet are intermittent drains; lavatories that can operate using less than 6 liters of water, and drain devices, called double-flush drain devices, through which you can flush using two different volumes of water. Flushing using two different volumes of water through the use of double-draining drains allowed to reduce water consumption by flushing with a smaller volume of water without using the full volume of water placed in the tank when the toilet is filled with urine or easily removed pieces, for example, litter or paper.

A double-pull release device is disclosed in previously published US patent application 2004/0083542. In this draining device, upward flow of the overflow tube is provided by means of a cam mechanism, by means of which the overflow tube is pushed upwards by pulling the wire connected to the button group. In this draining device, an overflow tube and a group of buttons are forced to function together so that the overflow tube cannot perform the function assigned to it without activating this special group of buttons. In addition, the trigger device contains too many mechanical parts, and one can imagine that the cost of their manufacture is high due to their structural complexity.

In the device according to US patent application 2004/0083542, by means of a hollow float used to lower a small volume of water, the adjusting rod is pulled upwards and the movable element, fitted with protrusions for coupling hooks on the overflow tube and connected to the adjusting rod, is forced to turn towards the overflow pipe while the tank is filled with water. In this mechanism, when the water from the tank is lowered, the movable element emerges from the interface with the overflow pipe under the action of gravity of the adjustment rod and the hollow float and the force applied to the movable element by means of an overflow pipe, and the overflow pipe with its gasket sits on the outlet.

The main difference between the release device disclosed in this patent application and the release device disclosed in US patent application 2004/0083542, besides the fact that parts of different geometric shapes are used, is that the mechanism for running a small volume of water works in different from the method described in US Patent Application 2004/0083542. In addition, the drain device according to the invention can be used in combination with standard lifting mechanisms for the overflow tube, which also differs from US patent application 2004/0083542. This is ensured by the possibility of connecting part of the so-called lifting lever with various lifting mechanisms.

In addition, this invention carried out the improvement of the drain device for the descent of two different volumes of water described in the published international patent application UO 2006/068628. In the draining device according to the invention, using an element by which mechanisms for lowering small and large volumes of water are separated by lowering the overflow tube, effectively using the center of gravity by arranging the trunnions of the float together and using the downward load applied by a hollow float for a small volume the inner space of the water tank is filled with water, contribute to a more reliable action of the drain device.

An object of the present invention is to provide a double-draining draining device that can be easily assembled, being durable, with which the user can drain the full volume or a predetermined volume of water in the tank; device that can be connected with various lifting mechanisms.

Another object of the invention is to provide a hollow float for a small volume that is filled with both air and water during the operation. It is designed to achieve a more efficient functioning of the descent of a small volume of water.

An additional object of the invention is to provide the possibility of an easier rotation of the floats for small and large volumes under the action of the buoyancy of water by advancing the connected arms of these floats.

The housing of the release device 3 shown in FIG. 8, includes a housing with openings 88 in the housing of the drain device, made in the form of a hollow cylinder and open at the bottom, containing the upper opening 83 of the housing of the drain device; two wall supports 82 mutually protruding outwards in the form of protrusions near the top; a lower protrusion 85 of the body of the release device, having an enlarged diameter at the lower side; two hooks 81 of the body of the release device, mutually protruding outwards in opposite directions in the form of protrusions directed from the lower protrusion 85 of the case of the release device. In the inner surface of the upper opening 83 of the housing of the drainage device, the channels 84 of the upper opening of the housing of the drainage device are mutually facing each other. In the upper surface of the housing 3 of the release device, near the upper opening 83 of the housing of the drain device, there is a hole 86 for attaching an adjustment rod. In addition, a pair of holes 87 for floats located next to each other and at the same level, which are located just above the lower lip 85 of the drain housing, are provided. Another pair of holes 87 for floats is made in the housing 3 of the drain device, on the same axes as the first pair of holes 87 for floats. Holes 88 in the housing of the drain, made in the housing of the drain, are used to pass water flow between the internal spaces of the housing of the drain and the tank during operation of the device. In addition, by using the protrusions 89 of the upper opening of the housing of the bleeding device, located circumferentially in the upper opening 83 of the housing of the bleeding device, minimize the contact surface between the housing 3 of the bleeding device and the overflow pipe 4 and facilitate easier movement of the tube up and down with less friction between the overflow tube 4 and the housing 3 of the drain device.

The overflow tube 4 shown in FIG. 9 contains the following mechanical parts: holes 91 for attaching a hook; overflow pipe guide 92; hook 93 for float for high volume; float hook 94 for small volume; and a seating surface 95 for rings and gaskets.

The overflow tube 4 shown in FIG. 9 is made in the form of a cylindrical hollow tube, open at the top and bottom, containing at the upper end two holes 91 for attaching hooks for attaching the lifting lever 5 of the release device; and also contains at the lower end a seating surface 95 for rings and a gasket, made with a reduced diameter, where two locking rings 14 and a bleeding gasket 15 between the locking rings 14 are located. On the overflow pipe there are two guides 92 of the overflow pipe, which are mutually arranged and extending from top to bottom . Near the lower end of the overflow tube guide 92, there is a hook 93 for a float for a large volume and a hook 94 for a float for a small volume. The hook 93 for the float for a large volume is made in the form of a protruding structure, protruding outward from the guide 92 of the overflow pipe in a specific place. The hook 94 for the float for a small volume is also made in the form of a protruding structure protruding outward from the guide 92 of the overflow tube above the said place. The hook 93 for the float for a large volume is shorter than the hook 94 for the float for a small volume, and the lower parts of the two hooks are adjusted to the angle of inclination. This area under the hook 93 for the float for a large volume is located below the area of the hook 94 for the float for a small volume. The guides 92 of the overflow pipe on the overflow pipe 4 are placed in the channels 84 of the upper opening of the housing of the drain device.

When assembling the double-descent release device A, which is the subject of the present invention shown in FIG. 1-3, the base 1 of the bleed valve is located in the outlet channel of the washroom of the toilet together with a gasket 2 of the base of the bleed valve on it. To fix the position of the base 1 of the drain valve, the support 8 of the base of the drain valve, the upper part of which is leaned against the fixation point in the tank, is connected to the base 1 of the drain valve. The flange 16 is positioned just above the base 1 of the bleed valve and is also positioned on the inside of the lower lip 85 of the body of the bleed device. The housing 3 of the drain device, in addition, attached to the hook mounting parts of the base 1 of the drain valve by means of hooks 81 of the housing of the drain device. The hooks of the lifting lever 5 of the draining device are attached to the holes 91 for attaching the hooks on the overflow tube 4. Due to the fact that the guides 92 of the overflow tube on the overflow tube 4 are directed through the channels 84 of the upper hole of the drain body, the overflow tube 4 is guided by the upper hole 83 of the housing drain device. On the seating surface 95 for the rings and the gasket of the overflow pipe 4, two retaining rings 14 are installed one above the other, and a drain pad 15 is installed between them. In the case that the overflow tube 4 is not pulled up, the discharge pad 15 closes the hole in the middle of the base 1 of the drain valve and prevents the flow of water from the tank into the toilet. FIG. 3 shows that the overflow tube 4 passes down through the hole in the middle of the flange 16. As the float pins 40 for a large volume and the float pins 50 for a small volume are inserted into the float holes 87 made in the housing 3 of the draining device, the float 9 for the large volume and float 10 for small volume are located inside the housing 3 of the drain device. In addition, their installation is performed in such a way that the pins 40 of the float for a large volume are located near the float 10 for a small volume, and the pins 50 of the float for a small volume are near the float 9 for a large volume. For this reason, the levers 47, 56 of the floats, by means of which they hold the trunnions 40, 50 of the floats for large and small volumes, are installed together so that they are facing towards each other, and the pins are inserted into the float holes 87 in the drain housing. The magnitude of the moment resulting from the action of the buoyancy force of the water increases due to the preservation of the length of the levers mentioned, and it is possible to tilt the floats 9, 10 towards the overflow tube 4 more easily. In addition, the overflow tube 4 is between the float 9 for large volume and the float 10 for small volume. The adjusting rod 11 for a small volume is also placed inside the housing 3 of the drain device; by means of its abutment protrusion 62, which abuts against the body of the drain, it rests against the surface just below the opening 86 for attaching the adjustment rod when the tank is filled with water; and at the same time, by means of connecting protrusions 66 for a float for a small volume in its lower part, it is attached to the hooks 58 of a float for a small volume for attaching an adjustment rod made in the float 10 for a small volume; the surface 65 for attaching the float for a small volume is placed in the hole 57 for the side

- 5 014601 of the adjustment of the adjusting rod for the float for a small volume, made in the float 10 for a small volume. The hollow float 12 for a small volume is also attached to the adjustment rod 11 for a small volume by means of its threaded surface 77 for the adjustment rod in a hollow float for a small volume.

As long as there is water in the tank, the contact surface 43 of the float for a large volume of the float 9 for a large volume and the contact surface 53 of the float for a small volume of the float 10 for a small volume are respectively in contact with the overflow pipe 4. Inside the internal space 46 of the float for a large volume is air, and the inner space 76 of the hollow float for a small volume is captured by the water inside the tank during replenishment, and the float 9 for a large volume, and the float 10 for a small volume turn up and down They are moored to the overflow tube due to the formation of pivot points represented by float pins 40 for large volume and pivot points represented by float pins 50 for small volume pivoting in float holes 87 in the housing 3 of the bleed device under the influence of buoyancy force.

By means of another mechanism, not shown in the drawings, which is not the subject of the present invention, water is released from the tank as a result of subsequent separation and lifting of the drain gasket 15 from the bottom 1 of the drain valve when lifting the lifting lever 5 of the drain device and the attached overflow tube 4.

When the overflow tube 4 is fully lifted up, the float hooks 45 for a large volume mate with the area below the float hook 93 for a large volume by contacting the large float hook 45 with a hook 93 for a large float 93 on the overflow tube 4, and the overflow tube 4 hangs on the float 9 for a large volume in this position.

When the water level reaches the lower level of the float 9 for a large volume, the lifting force of the water, urging the float 9 for a large volume to turn and tilt to the overflow pipe 4, begins to decrease, and under the action of gravity overflow pipe 4 the float 9 for a large volume is pressed down and out of the mating with the overflow tube 4 due to turning outwards. As a result, the overflow pipe 4 is disconnected from the hook 45 of the float for a large volume, and the bleed gasket (15) sits in its place on the base 1 of the bleeder valve. The volume of discharge water is a large volume between the highest water level in the tank and the lower level of the float 9 for a large volume.

On the other hand, for lowering a small volume of water it is required that the overflow pipe 4 be lifted up a shorter distance. When the overflow tube 4 is pulled upward over a certain short distance, the float hooks 55 for a small volume mate with the surface below the float hook 94 for a small volume by contacting the low volume float hook 55 with a hook 94 for the float for a small volume on the overflow tube 4, the overflow tube 4 hangs in this position on the float 10 for a small volume, and at this moment the water starts to drain.

When the water level is below the lower level of the hollow float 12 for a small volume, the gravity of the hollow float 12 for a small volume filled with air is transmitted to the control rod 11, which becomes heavier due to the fact that the volume 73 of the hollow float 12 for a small volume is filled water and, consequently, on the float 10 for a small volume, since the buoyancy force of the water decreases. As a result, the buoyant force of the water, the urging float 10 for a small volume to turn and tilt to the overflow pipe 4, begins to decrease, and under the action of gravity of the overflow pipe 4 together with the gravity of the hollow float 12 for a small volume with a capacity of 73 located above and filled with water, the float 10 for a small volume is pressed down and leaves the mating with the overflow tube 4 due to turning outwards. As a result, the overflow pipe 4 is disconnected from the hook 55 of the float for a small volume, and the bleed gasket 15 sits in its place, on the base 1 of the bleed valve. The volume of draining water is a small volume between the highest water level in the tank and the lower level of the hollow float 12 for a small volume or slightly below its lower level. To adjust the amount of water drained during a low volume run, the position of the hollow float 12 for a small volume can be changed by moving up or down using the threaded surfaces of the adjustment rod 11 for a small volume and the hollow float 12 for a small volume.

As an alternative to use, in addition to the lavatory cisterns, the double-cusp drain device A can also be used in various cisterns that contain liquid.
