Description

AN ELECTRONICALLY CONTROLLED FLUSHING SYSTEM

Relevant Technical Field

The present invention relates to the electronically controlled flushing systems.

Prior Art

Various flushing systems are employed in the toilets for providing the cleanliness and hygiene of a toilet bowl. Such flushing systems include a reservoir for the storage of the water, which is obtained from a source (such as a municipal water distribution network or an external storage tank) and which is used for cleaning, and the delivery of the water within the reservoir into the toilet bowl is realized by means of one or more control members, which are triggered mechanically, electronically or in a non-contact manner. To that end, the flushing systems comprise at least one opening for the transfer of water between the reservoir and the toilet bowl, and at least one cover, associated with the control member, for controlling the passage of water through said opening. When a user desires to transfer the water within the reservoir into the toilet bowl, he/she uses the control member to enable the cover to assume the open position and to enable the water to flow through the opening into the toilet bowl. With the advancing technology, various embodiments are developed to enable the discharge of water in a quantity dependent upon the actual need, particularly with a view to prevent the unnecessary water consumption in the flushing systems. Of these, the most commonly used are the structures that provide a dual discharge action. In said dual-discharge flushing systems, there are present two control members and the flushing system is enabled to deliver the water into the toilet bowl in two different quantities according to the control member that is triggered. However, with such type of systems, the delivery of the water into the toilet bowl is realized mechanically and it is not possible to precisely adjust the quantity of water to be transferred into the toilet bowl.

Additionally, in said flushing systems, the quantity of the water available within the reservoir may not be easily determined by a user. For example, said reservoir may be positioned inside a wall of the toilet room in order to increase the usage area in the public toilets, which in turn prevents the determination of the quantity of the water available within the reservoir. Consequently, it is not possible to understand whether or not the flushing system present in the toilet to be used is operational and whether or not an adequate quantity of the water is available within the reservoir unless the control member is triggered. Said triggering action usually takes place following the use of the toilet and the toilet bowl may not be cleaned following the use in case the flushing system is not operational and/or in case there is not an adequate quantity of the water available within the reservoir. This situation leads to serious hygiene problems especially in the public toilets.

Brief Description of the Invention

The electronically controlled flushing system developed according to the present invention is suitable for use in the delivery of water into a toilet bowl especially for cleaning said toilet bowl and comprises at least one reservoir with at least one bottom where the water obtained from a source is stored; at least one opening through which the water within the reservoir is delivered into the toilet bowl, said opening having at least one side connected with said reservoir and having at least one other side connected with the toilet bowl; at least one cover regulating the passage of water through said opening and having an open position at which the delivery of water from the reservoir into the toilet bowl is enabled and a closed position at which the delivery of water from the reservoir into the toilet bowl is prevented; at least one control member, which regulates the open/closed position of the cover, enables the cover to assume the open position for the delivery of the water within the reservoir into the toilet bowl and is able to be triggered mechanically, in a touch-operated manner or in a non-contact manner; at least two metal strip plates in said reservoir, which are positioned on a wall of said reservoir in such a way that they face one another and that the water filling into the reservoir remains between and contact them, at least one of said metal strip plates being positively charged and at least one other being negatively charged so that they have charge magnitudes equal to one another, wherein a first capacitance forms due to the equal opposite charges upon the contact of the water with said metal strip plates and wherein said first capacitance changes with the water contacting said metal strip plates and with the water height changing between said metal strip plates; at least one control unit connected to said strip plates, for enabling at least one of the strip plates to be positively charged and at least one other of the strip plates to be negatively charged with a magnitude that is same as that of the positive charge and thereby enabling a capacitance to form between the strip plates, for recording the maximum water level such that the height corresponding to one side of the strip plates is equal to the maximum water level possible to be present within the reservoir, for recording said first capacitance value in a way to indicate said maximum water level, for recording the varying capacitance values created by the change in the height of water between the strip plates in a way to indicate the different water levels within the reservoir, for measuring the capacitance between the strip plates according to predetermined periods, for determining the water level corresponding to the measured capacitance value and for identifying the quantity of water available within the reservoir based on the determined water level and the reservoir dimensions, for comparing the determined water level to the maximum water level and for controlling and regulating the operation of the flushing system based on said comparison; and at least one control panel, which is connected to the control unit and which comprises at least indicator for informing the user about the quantity of water available within the reservoir and thus 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 continuously determined according to certain periods 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 also 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

The cleaning of the toilet bowls following the use thereof is carried out via various flushing systems comprising at least one reservoir for the storage of the water to be used in cleaning and at least one control member controlling the delivery of the water within the reservoir into the toilet bowl. In such flushing systems, the delivery of different quantities of water into the toilet bowl may be provided with a view to reduce the consumption of water. However, in such type of flushing systems, as the quantity of the water to be delivered into the toilet bowl is controlled mechanically, it is not possible to precisely adjust said quantity. Moreover, it is not possible to determine whether or not the system is operational or whether or not an adequate quantity of water is available within the reservoir unless the control member is triggered in the flushing systems of the state of the art, and since the action of triggering the control member usually takes place following the use of the toilet, the toilet bowl may not be cleaned and serious hygiene problems come into play. In this regard, an electronically controlled flushing system is developed according to the present invention with a view to provide a solution to the aforesaid problems.

The electronically controlled flushing system (F), exemplary views of which are provided in Figures 1-4, is suitable for use in the delivery of water into a toilet bowl especially for cleaning said toilet bowl and comprises at least one reservoir (H) with at least one bottom (H3) where the water (S) obtained from a source (such as a municipal water distribution network or an external storage tank) is stored; at least one opening (HI) through which the water (S) within the reservoir (H) is delivered into the toilet bowl, said opening having at least one side connected with said reservoir (H) and having at least one other side connected with the toilet bowl; at least one cover (H2) regulating the passage of water through said opening (HI) and having an open position at which the delivery of water from the reservoir (H) into the toilet bowl is enabled and a closed position at which the delivery of water from the reservoir (H) into the toilet bowl is prevented; and at least one control member, which regulates the open/closed position of the cover (H2), enables 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 enables said cover (H2) to assume the closed position preferably once the water (S) received from the source has begun to refill the reservoir (H) following the delivery of the desired quantity of water (S) from the reservoir (H) into the toilet bowl) and is able to be triggered mechanically, in a touch-operated manner or in a non-contact manner. The developed flushing system (F) further comprises at least two metal strip plates (P) in said reservoir (H), which are positioned on a wall of said reservoir (H) in such a way that they face one another and that the water (S) filling into the reservoir (H) remains between and contact them, at least one of said metal strip plates being positively charged and at least one other being negatively charged so that they have charge magnitudes equal to one another, wherein a first capacitance forms due to the equal opposite charges upon the contact of the water (S) with said metal strip plates and wherein said first capacitance changes with the water (S) contacting said metal strip plates and with the water height changing between said metal strip plates; at least one control unit connected to said strip plates (P) preferably in a cabled manner, for enabling at least one of the strip plates (P) to be positively charged and at least one other of the strip plates (P) to be negatively charged with a magnitude that is same as that of the positive charge and thereby enabling a capacitance to form between the strip plates (P), for recording the maximum water level such that the height corresponding to one side of the strip plates (P) (preferably the height corresponding to the end of said strip plates that is farthest from the bottom (H3) of the reservoir (H)) is equal to the maximum water (S) level possible to be present within the reservoir (H), (preferably for recording the minimum water level such that the height corresponding to at least one other side of the strip plates (P) that is closer to the bottom (H3) than the abovementioned side (for example, the height corresponding to the end of said strip plates that is closest to the bottom (H3) of the reservoir (H)) is equal to the minimum water (S) level possible to be present within the reservoir (H)), for recording said first capacitance value in a way to indicate said maximum water level, for recording the varying capacitance values created by the change in the height of water (S) between the strip plates (P) in a way to indicate the different water levels within the reservoir (H), for measuring the capacitance between the strip plates (P) according to predetermined periods (for example, in an instantaneous manner), for determining the water level corresponding to the measured capacitance value and for identifying the quantity of water available within the reservoir (H) based on the determined water level and the reservoir (H) dimensions, for comparing the determined water level to the maximum water level and for controlling and regulating the operation of the flushing system (F) based on said comparison; and at least one control panel (K), which is connected to the control unit and which comprises at least one indicator (Kl) for informing the user about the quantity of water available within the reservoir (H) and thus 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 with the reservoir (H) thereof 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, the maximum level of water is present within the reservoir (H) wherein said cover (H2) is in the closed position preventing the passage of the water (S) through the opening. When the user wants to perform the transfer of water from the reservoir (H) into the toilet bowl, he/she triggers said control member and enables the cover (H2) to assume the open position. Upon the cover (H2) assuming the open position, the water (S) within the reservoir (H) reaches and passes through the opening (HI) to flow into the toilet bowl. As a result of the flow of the water (S) within the reservoir (H) into the toilet bowl, the level of water within the reservoir (H) and thus the level of water between the strip plates (P) change. Depending on the changing water level, the capacitance value between the strip plates (P) also changes, and this condition is detected by said control unit and the level of water is determined and monitored according to predetermined periods. Once the transfer of water into the toilet bowl has been complete, said cover (H2) assumes the closed position and the water is enabled to refill into the reservoir (H) from said source. Meanwhile, the level of water within the reservoir (H) and thus between the strip plates (P) changes, whereby the capacitance value varies depending on said change, said varying capacitance values are measured by the control unit, the water level within the reservoir (H) is accordingly determined and compared to said maximum water level. When the determined water level has become equal to the maximum water level and has remained equal to the same for a predetermined duration of time, the control unit determines that the adequate quantity of water is available within the reservoir (H) and the flushing system (F) is operating properly and notifies this situation to the user via said indicator (Kl). When the determined water level has not become equal to the maximum water level during another predetermined period of time or when the determined water level has exceeded the maximum water level, the control unit determines that the flushing system (F) is not operating properly and also notifies this situation to the user again via said indicator. In this way, whether or not an adequate quantity of water is available within the reservoir (H) or whether or not the flushing system (F) is operating properly may be easily detected without using the toilet and without triggering the control member, and consequently, the hygiene requirement may be enabled to be met according to the highest level. In a representative embodiment, such notification of the proper operation or malfunction state to the user may be achieved by means of said indicator (Kl) informing the water level within the reservoir (H) to the user 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 (Kl) emits the light in red color in case the water level within the reservoir (H) is low, whereas said illuminating member emits the light in green color in case the water level within the reservoir (H) is normal. According to a preferred embodiment of the invention shown in Figure 5, a printed circuit board (B) comprising multiple metal plate layers with lengths different from one another is used for said strip plates (P) and the capacitance change between said layers of different length is monitored by the control unit. In this way, a more precise measurement may be provided via a more practical application.

According to another representative embodiment of the invention, the control unit contains, as mentioned above, the minimum water level possible to be present within the reservoir (H) and the capacitance value corresponding to said level, wherein the control unit is also associated with said cover (H2). In this embodiment, after the cover (H2) has assumed the open position as a result of the control member being triggered, the water level within the reservoir (H) is monitored by the control unit through the measurement of capacitance and compared to the minimum water level. When it is detected by the control unit that the water level within the reservoir (H) has become equal to said minimum water level, the control unit enables said cover (H2) to assume the closed position and said opening to be closed. In this embodiment, the control unit preferably also controls the intake of water from the source, and in this way, it becomes possible to prevent the cover (H2) from remaining open while the intake of water to the reservoir (H) is in progress and thus obtain a reliable flushing system. According to a preferred embodiment of the invention, the developed flushing system (F) comprises at least one motion member (e.g. a motor) for providing the open/closed position of said cover (H2). In an embodiment, said motion member is preferably associated with the control member wherein when the control member is triggered by a user, the cover (H2) may assume the open position (and/or preferably the closed position). In another representative embodiment, said motion member is preferably associated with the control unit wherein said member controls the movement of the cover (H2) into the open position (and/or preferably the closed position) according to the water level (and/or quantity) determined in the control unit. In another preferred embodiment, said motion member is connected to both the control member and the control unit. For example, when a user triggers the control member to enable the transfer of water (S) from the reservoir (H) into the toilet bowl, he/she activates the motion member at the same time and the motion member in turn enables the cover (H2) to assume the open position. Meanwhile, the level of water (S) delivered from the reservoir (H) into the toilet bowl is determined by means of the control unit based on the measured capacitance values, and once the transfer of water (S) (preferably in a quantity that suits the need) 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 way, the opening and closing of the cover (H2) are controlled electronically in an automated manner and the level and/or quantity of the water (S) within the reservoir (H) is/are able to be monitored precisely.

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 water quantity and each corresponding to a capacitance value different from the others in order to enable the delivery 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 matched with separate control members and with capacitance values different from one another. When a user triggers the control member that is appropriate for his/her need, the capacitance value corresponding to the level that is based on such quantity is monitored by means of the control unit to enable the delivery of water (S) in a quantity matched with said control member and when the capacitance value measured between the strip plates (P) corresponds to the level matched with the desired quantity, it is determined that the desired quantity of water (S) has been delivered into the toilet bowl and the cover (H2) is enabled to assume the closed position preferably via a motion member and the transfer of water (S) from the reservoir (H) into the toilet bowl is enabled to stop. Accordingly, the delivery of water in a desired quantity into the toilet bowl may be achieved more precisely in a way that suits the need and thus, the water consumption may be reduced even further.

According to another preferred embodiment of the invention, the closing action of said cover (H2) may be achieved by means of the control member. For example, in case a user reaches, during the delivery of the water into the toilet bowl, the conclusion that the adequate quantity of water has been delivered into the toilet bowl, he/she triggers the control member again, and in this way, the user may enable the cover (H2) to assume the closed position preferably via a motion member, thereby interrupting the delivery of water from the reservoir (H) into the toilet bowl. Afterwards, the intake of water from the source to the reservoir (H) is restarted and the reservoir (H) is enabled to be refilled with water (S). Meanwhile, preferably the state of the rise in the level of water is presented to the user at predetermined periods (e.g. in an instantaneous manner) via said indicator (Kl).

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.

Owing to the electronically controlled flushing system (F) developed according to the present invention, the water level within the reservoir (H) may be continuously determined according to certain periods 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 also be provided with information regarding whether or not the flushing system (F) is operational. Consequently, it becomes possible to enhance the level of hygiene in an inexpensive, simple and practical manner especially in the public toilets.
