Description:
AN ELECTRONICALLY CONTROLLED FLUSHING SYSTEM Relevant Technical Field

The present invention relates to the electronically controlled flushing systems. Prior Art

The flushing systems are the systems employed for the purposes of cleaning the toilets and providing the hygiene for the same especially after their use. The flushing systems usually include a reservoir for the storage of the water to be used in cleaning a toilet bowl, a discharge equipment which enables the transfer of the water within the reservoir into the toilet bowl and, a conduit which connects the reservoir to the toilet bowl and through which the water is transferred from the reservoir into the toilet bowl. In cases where the flushing system is not in use, a cover included in the equipment closes said conduit to prevent the transfer of the water within the reservoir into the toilet bowl. When it is desired to transfer the water within the reservoir into the bowl, the cover is brought into the open position and the passage of the water through the conduit is permitted. Once the transfer of an adequate quantity of water has taken place from the reservoir, the cover is brought into the closed position and the water is prevented from passing into the bowl, thereby enabling the water to refill the reservoir. Today, as a result of the decline in the water resources, the flushing systems that enable the transfer of water into the toilet bowl on the basis of actual need are being developed with a view to prevent the unnecessary consumption of water. In said flushing systems, referred to as the dual discharge systems, the delivery of two different quantities of water is performed according to the need. To enable the delivery of said two different quantities of water, the flushing systems comprise two control members, each corresponding to one of said different quantities, wherein the quantity of water corresponding to the control member that has been triggered is delivered into the toilet bowl. However, the quantity of water to be transferred is determined by means of mechanical equipment in such systems and the use of mechanical equipment fails to be sufficient in allowing the precise adjustment of the quantity of water to be delivered. For instance, when it is intended to deliver only a small quantity of water into a toilet bowl, a situation may arise where a higher quantity of water than is necessary is transferred into the bowl unintentionally. Further, with said mechanical equipment, it is not possible to monitor the available quantity of water within the reservoir and it is not possible to determine, for example, whether or not the water is available within the reservoir or whether or not the flushing system is functioning properly, unless the control member is triggered.

Brief Description of the Invention An electronically controlled flushing system developed according to the present invention is suitable for use in the transfer of water for the purpose of cleaning a toilet bowl, wherein said system comprises at least one reservoir where the water obtained from a source is stored; at least one conduit through which the water within the reservoir passes to be delivered into the toilet bowl, said conduit having at least one side opening into said reservoir and at least one other side opening into said toilet bowl; at least one cover regulating the passage of water through said conduit and having an open position at which the passage of water through said conduit is permitted and a closed position at which the passage of water through said conduit is prevented; at least one control member regulating the open/closed position of the cover, enabling the cover to be brought into the open position for the delivery of the water within the reservoir into the toilet bowl and being able to be triggered mechanically, in a touch-operated manner or in a non- contact manner; at least one pipe in said reservoir, said pipe being positioned in a way to enable the water within the reservoir to fill into and to rise inside the same, wherein the water in said pipe is on the same level as the water within the reservoir; at least one floating member which is positioned into said pipe, floats on the water inside said pipe and has a color that enables it to be distinguished from the water; at least one sensor measuring the distance of said floating member from itself and thereby enabling to determine the quantity of water available within the reservoir; at least one control unit for recording the predefined maximum water level to be present within the reservoir, for receiving the values measured by the sensor, for determining the water level within the reservoir based on such received values and identifying the quantity of water available within the reservoir according to the determined water level and the reservoir dimensions, and for comparing the predefined water level to the determined water level to control and regulate the operation of the flushing system based on the predefined water level and the determined water level; and at least one control panel, which is connected to the control unit and which comprises at least one indicator for informing the user about the operational status of the flushing system based on the water level and/or water quantity determined by the control unit. Owing to the electronically controlled flushing system developed according to the present invention, the water level within the reservoir may be instantly determined and informed to the user in a precise manner. Thus, particularly in the wall-embedded flushing systems, the user may be aware of the quantity of water available within the reservoir and accordingly, the user may be provided with information regarding whether or not the flushing system is operational. As a result, it becomes possible to enhance the level of hygiene in an inexpensive, simple and practical manner especially in the public toilets.

Description of the Invention

Today, various flushing systems are employed for providing the hygiene in the toilets. Such flushing systems comprise a reservoir for the storage of the water that is to be delivered into a toilet bowl wherein the quantity of water received into said reservoir and delivered from said reservoir into the toilet bowl is adjusted via mechanical equipment. However, the mechanical equipment fails to be sufficient in allowing the precise adjustment of the quantity of water, and in the dual discharge flushing systems featuring the delivery of two different quantities of water into a toilet bowl, for instance, the problems may arise where a greater quantity of water is delivered into the bowl despite the intention to deliver a smaller quantity of the same. Moreover, it is not possible to monitor with the mechanical equipment the quantity of water available within the reservoir and any likely problem arising in the flushing system goes unnoticed by a user unless said flushing system is actually used. Consequently, an electronically controlled flushing system is developed according to the present invention for providing a solution for the aforementioned problems.

The electronically controlled flushing system (F), exemplary views of which are provided in Figures 1 -4, is suitable for use in the transfer of water for the purpose of cleaning a toilet bowl, wherein said system comprises at least one reservoir (H) where the water (S) obtained from a source (such as a municipal water distribution network or a storage tank) is stored; at least one conduit (H1 ) through which the water (S) within the reservoir (H) passes to be delivered into the toilet bowl, said conduit having at least one side opening into said reservoir (H) and at least one other side opening into said toilet bowl; at least one cover (H2) regulating the passage of water through said conduit (H1 ) and having an open position at which the passage of water through said conduit (H1 ) is permitted and a closed position at which the passage of water through said conduit (H1 ) is prevented; and at least one control member regulating the open/closed position of the cover (H2), enabling the cover (H2) to assume the open position for the delivery of the water (S) within the reservoir (H) into the toilet bowl (and/or enabling said cover (H2) to assume the closed position preferably once the water (S) has begun to refill the reservoir (H) following the transfer of the water (S) within the reservoir (H) into said bowl) and being able to be triggered mechanically, in a touch-operated manner or in a non-contact manner. The flushing system (F) developed further comprises at least one pipe (B) in said reservoir (H), said pipe being positioned in a way to enable the water (S) within the reservoir (H) to fill, preferably from a lower portion thereof, into and to rise inside the same (for example, positioned in a way to make an acute angle with the bottom of the reservoir (H) or to lie perpendicularly to said bottom), wherein the water (S) in said pipe is on the same level as the water within the reservoir (H); at least one floating member (B1 ) which is positioned into said pipe (B), floats on the water (S) inside said pipe (B) and has a color (e.g. white, red or a metallic color) that enables it to be distinguished from the water (S); at least one sensor (A) (preferably an IR (infrared) sensor) preferably positioned at the pipe (B) (for example inside the pipe (B)) in a way to be located in an upper side of said pipe (B), measuring the distance of said floating member (B1 ) from itself and thereby enabling to determine the quantity of water available within the reservoir (H); at least one control unit for recording the predefined maximum water level (or quantity) to be present within the reservoir (H), for receiving the values measured by the sensor (A), for determining the water level within the reservoir (H) based on such received values and identifying the quantity of water available within the reservoir (H) according to the determined water level and the reservoir (H) dimensions, and for comparing the predefined water level (or quantity) to the determined water level (and/or quantity) to control and regulate the operation of the flushing system (F) based on the predefined water level (or quantity) and the determined water level (and/or quantity); and at least one control panel (K), which is connected to the control unit and which comprises at least one indicator (K1 ) for informing the user about the operational status of the flushing system (F) based on the water level and/or water quantity determined by the control unit and which preferably has the control member positioned therein. Said flushing system (F) is preferably a system disposed inside a wall in an area where the toilet bowl is present (i.e. it is a wall-embedded system). According to an exemplary manner of operation of the invention, said cover (H2) is in the closed position such that it prevents the passage of water (S) through the conduit (H1 ), and in this case, the water (S) received from a source fills into the reservoir (H) and thus into the pipe (B), and, upon the level of water (S) rising within the reservoir (H) and the pipe, the floating member (B1 ) that floats on the water (S) inside the pipe (B) also rises along with the increasing level of the water. Meanwhile, said sensor (A) measures the distance of the floating member (B1 ) from itself at certain time intervals (e.g. in an instantaneous manner) and transmits such measured values to the control unit after each measurement (or at predetermined periods). Based on said measured value, the control unit determines the height of the water (S) within the reservoir (H), and preferably, it determines the quantity of water (S) available within the reservoir (H) taking into account the dimensions of the reservoir (H) and compares, preferably in an instantaneous manner, such determined value to the predefined maximum value. When the water (S) within the reservoir (H) has reached the maximum value, the intake of water (S) from the source to the reservoir (H) is stopped in case the flushing system (F) is functioning properly. Thus, it is determined, as a result of a comparison performed in the control unit, that the level (or quantity) of the water (S) within the reservoir (H) has reached the maximum value stored in the control unit and that it remains constant at this value. Based on this determination, it is concluded that a sufficient quantity of water (S) is available within the reservoir (H), and hence, the flushing system (F) is functioning properly, and this condition is informed to a user through said indicator (K1 ). On the other hand, in case the determined water level (and/or quantity) becomes fixed at a value different from the predefined value, the presence of a malfunction in the flushing system (F) is notified to the user again through said indicator (K1 ). According to a representative embodiment, said action of notifying the user about the proper functioning or malfunction may be achieved by way of said indicator (K1 ) informing the user about the water level in the reservoir (H) according to certain value ranges. In this embodiment, for example, at least one illuminating member is used and the part up to the value that corresponds to the water (S) level (or quantity) within the reservoir (H) is shown in a certain color (e.g. green). In another embodiment, an illuminating member that emits light in different colors for different water levels is used, wherein it may be provided, for example, that the illuminating member disposed on the indicator (K1 ) emits the light in red color in case the water level within the reservoir (H) is high or low, whereas said illuminating member emits the light in green color in case the water level within the reservoir (H) is normal. In this way, the user may determine, prior to using the toilet, whether or not the flushing system (F) is properly functioning and whether or not an adequate quantity of water is available within the reservoir (H) and it may be ensured that a higher level of hygiene is achieved in an inexpensive, simple and practical manner particularly in the public toilets.

According to a preferred embodiment of the invention, the open/closed position of said cover (H2) is provided by means of at least one motion member (for example a motor). In one embodiment, said motion member is associated with the control member and is able to bring the cover (H2) into the open and/or closed position upon the control member being triggered. In another embodiment, said motion member is associated with the control unit wherein it controls the opening and closing of the cover (H2) according to the water level (and/or quantity) determined in the control unit. In yet another embodiment, said motion member is associated both with the control member and the control unit. For example, when the control member is triggered for the delivery of water (S) from the reservoir (H) into the toilet bowl, said control member activates the motion member and the motion member in turn enables the cover (H2) to assume the open position. In the meantime, the water (S) being transferred from the reservoir (H) into the toilet bowl is determined through the measurement of the level of water (S) by the floating member (B1 ) and the sensor (A) and transmission of said measurement value to the control unit, and once the transfer of water (S) has been complete, the control unit activates the motion member and the motion member in turn enables the cover (H2) to assume the closed position. In this case, the control unit preferably stores the minimum value (level and/or quantity) of water (S) to be present within the reservoir (H) and the control unit enables the cover (H2) to close upon the value measured by the sensor (A) having reached said minimum value. In this way, the opening and closing of the cover (H2) are controlled electronically and the level and/or quantity of the water (S) within the reservoir (H) is/are able to be monitored precisely.

According to another preferred embodiment of the invention, the closing action of said cover (H2) may be achieved by means of the control member. According to an alternative embodiment of the invention, said pipe (B) may have the structure of a tube, while it is also possible for the same to have a mesh structure containing the openings with an area smaller than the size of the floating member (B1 ).

According to another representative embodiment of the invention, the flushing system (F) features the ability to enable the cleaning of the toilet bowl to be performed with at least two quantities of water that are different from one another, and to achieve this purpose, said system comprises at least two control members each corresponding to a separate quantity in order to enable the transfer of different quantities of water (S) into the toilet bowl. In this embodiment, the different water quantities to be used in cleaning the toilet bowl are recorded in the control unit in a way associated with separate control members and when a user triggers a control member that is appropriate for his/her need, the quantity of water (S) that is matched with said control member is delivered into the bowl. In this embodiment, the flushing system (F) further comprises at least one motion member preferably connected to the cover (H2), control members and control unit. Thus, when a user wants for instance to deliver a first quantity of water (S) into the toilet bowl, he/she triggers the respective control member and the cover (H2) assumes the open position. Meanwhile, the level of water (S) is measured continuously by the sensor (A) and the control unit continuously calculates at predetermined periods the amount of water (S) being transferred. When the calculated water quantity has become equal to the first quantity, the control unit activates the motion member and the motion member in turn brings the cover (H2) into the closed position to thereby stop the flow of water into the toilet bowl. In this way, the delivery of a desired quantity of water into the toilet bowl may be realized more precisely in a way that suits the actual need, and as a result, the consumption of water may be reduced even further. According to another representative embodiment of the invention, the flushing system (F) developed further comprises at least one audible warning member for warning the user about the operating status. Thus, it may be ensured that the flushing system (F) is used more efficiently by the user.

According to another alternative embodiment of the invention, said floating member (B1 ) preferably has a round form. In this way, the amount of friction may be reduced, thereby enabling the floating member (B1 ) to float easily and conveniently on the water (S). According to another preferred embodiment, the flushing system (F) developed further comprises at least one connecting member (B2) serving the function of securing said pipe (B) inside the reservoir (H). Said connecting member (B2) is preferably in the form of a bar so that the pipe (B) is positioned at a certain distance from the walls of the reservoir (H) in order to enable the correct determination of the level of the water (S).

Owing to the electronically controlled flushing system (F) developed according to the present invention, the water level within the reservoir (H) may be instantly determined and informed to the user in a precise manner. Thus, particularly in the wall-embedded flushing systems (F), the user may be aware of the quantity of water (S) available within the reservoir (H) and accordingly, the user may be provided with information regarding whether or not the flushing system (F) is operational. As a result, it becomes possible to enhance the level of hygiene in an inexpensive, simple and practical manner especially in the public toilets.
