Description

FLUSHING SYSTEM MECHANISM

Subject of the Invention

The invention relates to a flushing system mechanism, which enables the water within a flush tank to be discharged into a toilet bowl.

State of the Art

The toilets require to be cleaned following the use and the flush tanks and flushing systems are employed for this purpose. Preferably, a certain quantity of water determined based on the preferences and the needs is collected within the flush tank and the toilet is enabled to be cleaned by way of discharging said water into the toilet bowl after the use.

According to the state of the art, the system for flushing a toilet bowl after the use is triggered preferably by means of a mechanical lever and/or button and in response to the triggering action, the water within the flush tank is enabled to discharge into the toilet bowl, thereby cleaning said toilet bowl. Depending on the triggering action, the flushing system mechanism opens the connection between the flush tank and the toilet bowl for a certain time and enables the water within the flush tank to be discharged into the toilet bowl.

In the flushing system mechanisms according to the state of the art, the duration for which the connection between the flush tank and the toilet bowl is to remain open may vary depending on the flow rate of the water coming from the flush tank. In other words, the quantity of water that is discharged into the toilet bowl may vary depending on the flow rate of the water. At present, the rimless toilet bowls in other words toilet bowls without ring are frequently preferred because they are hygienic. In such toilet bowls, the flushing apparatus are utilized, which guide the water and reduce the water flow rate in order to prevent the splash of water. Said apparatus may cause a change in the flow rate of the water coming from the flush tank into the toilet bowl. Likewise, the flow rate of the water coming from the flush tank may also vary depending on the height and width of the flush tank.

In order to save water and prevent the unnecessary water consumption, the two-stage discharge systems are utilized. The two-stage discharge systems perform the flushing process using more than one volume of water, preferably two different volumes of water, depending on the needs. As a result of the flow rate variations, it is not possible to achieve the desired extent of water saving due to the problem of discharging into the toilet bowl a quantity of water that is larger or smaller than desired or it is not possible to achieve the flushing process in the desired manner due to the discharge of an inadequate quantity of water.

With the invention, a flushing system mechanism is developed, which ensures that every time a desired volume of water is discharged into the toilet bowl independently of the flow rate of the water coming from the flush tank into the toilet bowl.

Object of the Invention

An object of the invention is to develop a flushing system mechanism, which ensures that every time the same volume of water is discharged into the toilet bowl independently of the flow rate of the water coming from the flush tank into the toilet bowl.

Another object of the invention is to develop a flushing system mechanism, in which the connection between the flush tank and the toilet bowl remains open until the desired quantity of water has been discharged into the toilet bowl.

Another object of the invention is to develop a flushing system mechanism, which may be used with all the toilets and flush tanks irrespective of the geometry and dimensions of the flushing apparatus and the flush tank.

Detailed Description of the Invention

The invention relates to a flushing system mechanism, which enables the water within a flush tank to be discharged into a toilet bowl. More particularly, the invention relates to a flushing system mechanism, which enables the connection between the flush tank and the toilet bowl to be kept open until the desired quantity of water has been discharged into the toilet bowl and is therefore able to perform the flushing every time with the same quantity of water independently of the flow rate of the water flowing into the toilet bowl and thus independently of the geometry and dimensions of the flushing apparatus and the flush tank.

In the toilet bowl flushing systems, the flushing process is performed by way of discharging the water within a flush tank into the toilet bowl in a controlled manner by means of a mechanism. On the bottom of the flush tank, there is present a flush tank opening (6) that is opened into the toilet bowl. The water flow into the toilet bowl is controlled depending on the opening and closing of said flush tank opening (6). In the practices of the state of the art, an overflow pipe (2) is provided in order to prevent a quantity of water that is more than necessary from filling into the flush tank and from overflowing. The overflow pipe (2) is used for the purpose of draining the water within the flush tank into the toilet bowl in case the water level within the flush tank exceeds a certain level. Another intended use for the overflow pipe (2) is to enable the flush tank opening (6) to open when it is desired to flush the toilet bowl and to enable the same to close once the flushing is complete. A seal piece (7) is available at the lower end of the overflow pipe (2). The seal piece (7) moves up and down depending on the upward and downward motion of the overflow pipe (2) and thus enables the flush tank opening (6) to open and close.

Depending on the upward motion of the overflow pipe (2), a first volume of water or a second volume of water is enabled to discharge into the toilet bowl. The upward motion of the overflow pipe (2) is provided by a first water volume discharge rod (11) or a second water volume discharge rod (12). The first water volume discharge rod (11) is fixed on the overflow pipe (2). Depending on the upward motion of the first water volume discharge rod (11), the overflow pipe (2) also moves upwards and enables a first volume of water to be discharged into the toilet bowl. A second water volume discharge rod is fixed on a trigger piece (8), wherein depending on the upward motion of the second water volume discharge rod (12), the trigger piece (8) also moves upwards and enables the overflow pipe (2) to rise, thereby enabling a second volume of water to be discharged into the toilet bowl.

The force that enables a first water volume discharge rod (11) or a second water volume discharge rod (12) to move upwards is applied by the user. It is desired to have the overflow pipe (2) automatically return to its original position, after the flushing process has taken place depending on the upward motion of a first water volume discharge rod (11) or a second water volume discharge rod (12). However, that the overflow pipe (2) returns to its original position and the seal piece (7) thus closes the flush tank opening (6) before the flushing process is completed may result in the failure to achieve the flushing process in the desired manner. On the other hand, the possibility that a second water volume discharge rod (12) could also correspondingly move upwards even though only a first water volume discharge rod (11) has been moved upwards may cause a quantity of water that is more than necessary to be discharged into the toilet bowl.

In the flushing system mechanism according to the invention, a lock piece (3) is utilized for the purpose of preventing the overflow pipe (2) from returning to its original position, i.e. for the purpose of preventing the flush tank opening (6) from being closed, before the flushing process is completed and for the purpose of preventing a second water volume discharge rod (12) from moving in connection with the motion of a first water volume discharge rod (11). Said lock piece (3) prevents the downward motion of the overflow pipe (2) unti l the flushing process is completed, i.e. until a desired quantity of water is discharged into the toilet bowl, and prevents the upward motion of a second water volume discharge rod (12) when a first water volume discharge rod (11) is pulled upwards.

The lock piece (3) is supported on the body of the flushing system via a lock piece body bearing pin (32) and surrounds the overflow pipe (2). The lock piece body bearing pin (32) is capable of rotating about its central axis. The motion of the lock piece (3) on the lock piece body bearing pin (32) is provided by at least one float (4) and at least one float connection rod (5) linked to said float (4).

The float (4) is disposed within the flush tank and moves according the quantity of water within the flush tank. There is present a float air chamber (41) in the lower portion of the float (4). While the water is available within the flush tank, the air in the float air chamber (41) applies a force to push the float (4) upwards. There is present a float water chamber (42) in the upper portion of the float (4). Said float water chamber (42) is filled with the water available in the flush tank. In a case where the water within the flush tank has been drained, the water present in the float water chamber (42) applies a downward force on the float (4) and supports the float (4) in moving downwards as a result of its own weight.

The upward force applied by the air in the float air chamber (41) and the downward force applied by the weight of the water present in the float water chamber (42) and the weight of the float (4) itself are transferred via the float connection rod (5) to the lock piece (3). One end of the float connection rod (5) is attached to the float (4), while the other end thereof is attached to the lock piece (3). The lock piece float connection rod pin (33) is located on the lock piece (3). Said lock piece float connection rod pin (33) penetrates the lock piece pin housing (51) disposed on the float connection rod (5). As a result, the lock piece (3) is enabled to move in connection with the motion of the float connection rod (5). In other words, the lock piece (3) is pushed upwards or pulled downwards depending on the force applied by the float (4) on the float connection rod (5).

The lock piece float connection rod pin (33) is located on one end of the lock piece (3) and the lock piece hook (31) is located on the other end of the same. Because the lock piece (3) is supported via the lock piece body bearing pin (32) that is disposed at a point between the lock piece float connection rod pin (33) and the lock piece hook (31), the lock piece float connection rod pin (33) and the lock piece hook (31) move in opposite directions. In other words, in case the lock piece float connection rod pin (33) moves upwards, the lock piece hook (31) moves downwards, whereas in case the lock piece float connection rod pin (33) moves downwards, the lock piece hook (31) moves upwards. In a case where no force is applied on a second water volume discharge rod (12) and the flush tank is full with water, the end of the lock piece hook (31) rests against the trigger piece outer surface (81). Depending on the force applied by the float (4) on the float connection rod (5), the end of the lock piece hook (31) applies a force on the trigger piece outer surface (81) and hinders the motion of the trigger piece (8). Consequently, when an upward force is applied on a first water volume discharge rod (11) and said first water volume discharge rod (11) moves upwards, the second water volume discharge rod (12) is prevented from moving also in connection with such motion. An exemplary case is shown in Figure 1. In this case, even though a lifting force is being applied by the float (4) on the float connection rod (5) and the lock piece (3), the lock piece (3) and thus the float (4) and the float connection rod (5) are not able to move since the end of the lock piece hook (31) is resting against the trigger piece outer surface (81).

Depending on the upward motion of the first water volume discharge rod (11), the overflow pipe (2) moves upwards and enables the flush tank opening (6) to open, thereby permitting the flow of water from the flush tank into the toilet bowl. The container (9) having an air gap inside thereof, which is connected to the overflow pipe (2), prevents the overflow pipe (2) from closing the flush tank opening (6) until a first desired quantity of water has been discharged into the toilet bowl. The position of the container (9) with air gap on the overflow pipe (2) may be set in line with the preferences and the needs; in other words, the quantity of water that is to be discharged into the toilet bowl depending on the upward pull applied to the first water volume discharge rod (11) may be adjusted.

Because a lifting force is still being applied on the float (4) and said force is being transmitted to the lock piece (3) via the float connection rod (5) while the overflow pipe (2) is being lifted and the flow of water is thus taking place into the toilet bowl as a result of the upward motion of the first water volume discharge rod (11), the lock piece (3) prevents the motion of the trigger piece (8). Because a lifting force is still being applied on the float (4) even when a first quantity of water has been discharged into the toilet bowl, the lock piece hook (31) continues to apply a force on the trigger piece outer surface (81) and thus the trigger piece (8) is unable to move. When it is desired to discharge a second volume of water into the toilet bowl, it is necessary to pull upwards the second water volume discharge rod (12). The second water volume discharge rod (12) is linked to the trigger piece (8) and depending on the motion of the second water volume discharge rod (12), the trigger piece (8) also moves in the same direction. Depending on the upward motion of the trigger piece (8), the top surface of the trigger piece (8) rests against the overflow pipe trigger piece resting surface (22) and the trigger piece (8) enables the overflow pipe (2) to also move upwards. Along with the upward motion of the overflow pipe (2), the seal piece (7) also moves upwards, thereby enabling the flush tank opening (6) to open and the water to discharge from the flush tank into the toilet bowl.

While the trigger piece (8) is moving upwards, the lock piece (3) remains stationary and the lock piece hook (31) becomes increasingly closer to the bottom surface of the trigger piece (8), and at a point, the lock piece hook (31) becomes released from the trigger piece (8) and moves toward the underneath of the trigger piece (8) and enters below the overflow pipe tab (21) located on the side surface of the overflow pipe (2). The lock piece hook (31) that enters below the overflow pipe tab (21) prevents the downward motion of the overflow pipe (2). Therefore, as long as a force is being applied on the float (4), i.e. as long as the water is available within the flush tank, the overflow pipe (2) is prevented from moving downwards and from closing the flush tank opening (6).

Once the water within the flush tank has been discharged into the toilet bowl, i.e. once the flushing process has been performed, no lifting force is applied on the float (4), due to the drop in the water level within the flush tank. However, the water that is present in the float water chamber (42) applies a force on the float in the direction of the gravity. As a result of said force and the weight of the float (4) itself, the float (4) applies a downward force on the float connection rod (5) and said float connection rod (5) in turn pulls down the lock piece (3) via the lock piece float connection rod pin (33). Depending on the downward motion of the lock piece float connection rod pin (33), the lock piece hook (31) moves upwards. With the upward motion of the lock piece hook (31), the end of the lock piece hook (31) is withdrawn from its position below the overflow pipe tab (21) and the trigger piece (8) and permits the downward motion of the trigger piece (8) and the overflow pipe (2). In other words, in case the water level within the flush tank is below the float (4) and thus no lifting force is being applied on the float (4), the lock piece hook (31) does not contact the overflow pipe (2) and the trigger piece (8). Upon the downward motion of the overflow pipe (2), said overflow pipe (2) and the seal piece (7) close the flush tank opening (6) and enable the flush tank to be refilled with water.

As a result of the water filling into the flush tank, a lifting force will start to be applied again on the float (4). In case said lifting force overcomes the force applied by the water present in the float water chamber (42) and the force applied by the float (4) as a result of its weight, the float (4) will move upwards and will apply an upward force on the float connection rod (5). As a result of this force, the lock piece hook (31) will move downwards again and rest against the trigger piece outer surface (81). Unless the system is triggered with the second water volume discharge rod (12), i.e. unless the trigger piece (8) is lifted, the positions of the lock piece (3), the float connection rod (5) and the float (4) will not change. The position of the float (4) on the float connection rod (5), i.e. the height of the float (4) from the bottom of the flush tank, may be adjusted. In other words, the float (4) may be fixed on the float connection rod (5) at any height. In this way, it becomes possible to set a quantity of water, after the discharge of which from the flush tank the lock piece (3) is to move downwards. In other words, it is possible to set a quantity of water, after the discharge of which into the toilet bowl the flush tank opening (6) is to be closed. In this way, it is possible to adjust the quantity of water to be used for flushing.

With the flushing system mechanism according to the invention, the flush tank opening (6) is enabled to remain open, irrespective of the water flow rate and other variables, until a predetermined preferred quantity of water has been discharged from the flush tank into the toilet bowl.
