- the toilet system [100] includes the toilet arrangement [102] and a self-regulated cleaning system [104].
- the self-regulated cleaning system [104] is provided to perform automatic cleaning of the toilet arrangement [102], at regular intervals. Structure and arrangement of the toilet arrangement [102] will be discussed hereinafter.
- the toilet arrangement [102] is a typical toilet facility provided to allow users to defecate in good sanitary condition.
- the toilet arrangement [102] includes a toilet bowl [106] and the flush tank [108].
- the toilet bowl [106] is an open-top vessel, which is provided to receive users' defecate, as the user performs defecation thereon.
- the flush tank [108] is provided to store water, which may be supplied to the toilet bowl [106] for removing defecate (termed as flushing action) therefrom.
- the flush tank [108] includes a storage tank [110], a fill valve [112], a flush valve [114], and a face plate [116].
- the storage tank [110] is adapted to store water therein.
- the storage tank [110] is fluidly connected to a water source via the fill valve [112], to receive water therein.
- the storage tank [110] is fluidly connected to the toilet bowl [106] via the flush valve [114], to allow exit of water therefrom.
- water stored in the storage tank [110] is transferred to the toilet bowl [106] via the flush valve [114], for enabling flushing action thereon.
- the storage tank [110] supports the fill valve [112], the flush valve [114], and the face plate [116], which in conjunction with each other facilitates filling and emptying of the storage tank [110] when required.
- the fill valve [112] is provided between a fluid connection of the storage tank [110] with the water source, and enables filling of the storage tank [110] upon actuation. Particularly, the fill valve [112] is automatically actuated when a water level in the storage tank [110] reaches below a lower threshold level, to allow filling of the storage tank [110] with fresh water received from the water source. Moreover, the fill valve [112] is deactivated when water level in the storage tank [110] reaches above an upper threshold value, to stop filling of the storage tank [110].
- the flush valve [114] and the face plate [116] in conjunction, allows exit of water from the storage tank [110] to the toilet bowl [106] upon users demand.
- the flush valve [114] is provided between a fluid connection of the storage tank [110] with the toilet bowl [106], and enables transfer of water therebetween upon actuation. Particularly, when actuated (opened), the flush valve [114] transfers water from the storage tank [110] to the toilet bowl [106], for performing flushing action. Moreover, when deactivated (closed), the flush valve [114] restricts transfer of water from the storage tank [110] to the toilet bowl [106], for stopping flushing action. Actuation and deactivation of the flush valve [114] is manually enabled with use of the face plate [116].
- the face plate [116] is operably connected to the flush valve [114], such that the flush valve [114] is actuated when at least a button on the face plate [116] is pressed.

Positioning of the face plate [116] relative to the flush tank [108] does not limit the scope of the invention. In the alternate embodiment, when the face plate [116] is positioned remote to the flush tank [108], the face plate [116] is pneumatically connected to the flush valve [114], which enable the exit of the fluid from the storage tank [110] upon pressing of the face plate [116].
- the self-regulated cleaning system [104] is provided to perform automatic cleaning of the toilet bowl [106] of the toilet arrangement [100] based on a predefined self-regulated cleaning method/process, at regular intervals.
- the self-regulated cleaning system [104] comprises of a hydrogen peroxide generator [122] and a control system [124].
- the hydrogen peroxide generator [122] is an electrolytic cell, positioned within the storage tank [110]. When actuated, the hydrogen peroxide generator [122] releases a predefined volume of hydrogen peroxide in the storage tank [110] of the flush tank [108]. In particular, the hydrogen peroxide generator [122] is adapted to release hydrogen peroxide within a predefined range of 2 - 30% volume of the storage tank [110], preferably between 3-6 % volume of the storage tank [110]. Notably, the hydrogen peroxide generator [122] generates the hydrogen peroxide by way of an electrolytic chemical reaction. As the hydrogen peroxide generator [122] is positioned within the storage tank [110], the hydrogen peroxide so generated is released in water stored in the storage tank [110] of the flush tank [108]. Furthermore, when deactivated, the hydrogen peroxide generator [122] stops generation of the hydrogen peroxide.
- FIG. 3 shows a block diagram of the control system [124] of the self-regulated cleaning system [104].
- the control system [124] is provided to controllably actuate the hydrogen peroxide generator [122], to allow self-regulated production of hydrogen peroxide in the storage tank [110] of the flush tank [108].

- the storage unit [140] is adapted to receive the first signal and the second signal from each of full float switch [136] and the half float switch [138], and correspondingly count the number of flushes actions performed.
- the storage unit [140] comprises of a counter that is incremented upon receipt of signals from each of full float switch [136] and the half float switch [138].
- the storage unit [140] increments the counter by one (1), upon receipt of the first signal from the first float switch [136]. Further, the storage unit [140] increments the counter by half (0.5), upon receipt of the second signal from the second float switch [138]. In addition to the count of the number of flush actions, the storage unit [140] also records date and time of previous pressing of the face plate [116], for flushing. Further, as the storage unit [140] is an EPROM memory, the data in the counter can be erased, when required by the control unit [132]. Although, the storage unit [140] is described as the EPROM memory, various other types of memory as the storage unit [140] may also be contemplated
- the display unit [128] which is a user-interactive LED based touch screen, is in communication with the storage unit [140] of the flush counter [126], via the control unit [132]. Particularly, the control unit retrieves a number of parameters from the storage unit [140] of the flush counter [126], and transmit it to the display unit [128].
- the display unit [128] displays the number of parameters of the toilet arrangement [102], by obtaining data from the storage unit [140] of the flush counter [126] via the control unit [132]. For example, the display unit [128] displays date, time, number of flushes, cleaning mode, duration of cleaning, number of cleaning cycle, life of cleaning solution and water in the flush tank [108].
- the display unit [128] retrieves the count of the number of flush actions stored in the storage unit [140] of the flush counter [126] via the control unit [132], and thus display the count of the number of flush actions.

Uneven operational parameters of the toilet arrangement [102] includes, but is not limited to, improper operation of the toilet arrangement [102], a low water supply in the flush tank [108], a blockage in the drain pipe of the toilet arrangement [102], and/or failure of any of the components of the self-regulated cleaning system [104]. In such cases, the safety unit [130] guides the control unit [132] to halt/ stop/ not initiate execution of the self-regulated cleaning method/process, for cleaning the toilet arrangement [102].
- the control unit [132] is electrically connected to each of the hydrogen peroxide generator [122], the storage unit [140] of the flush counter [126], and the safety unit [130]. Further, the control unit is operably connected to the flush valve [114]. With such arrangement, the control unit [132] enables cleaning of the toilet bowl [106] based on the predefined self-regulated cleaning method/ process [142]. Particularly, the control unit [132] is preprogrammed to follow certain steps of performing the self-regulated cleaning method/ process [142]. Notably, the control unit [132] is electrically connected to the storage unit [140] of the flush counter, to obtain the data for the count of the number of flush actions performed in the face plate [116].
- control unit [132] is electrically connected to the hydrogen peroxide generator [122], for enabling controlled actuation and deactivation of the hydrogen peroxide generator [122] thereof. Moreover, the control unit [132] is operably connected to the flush valve [114], for enabling controlled actuation and deactivation of the flush valve [114] thereof. Notably, the control unit [132] performs the aforementioned actions, to execute the predefined self-actuating cleaning method/ process [142] on the toilet bowl [106] of the toilet arrangement [102].
- the self-regulated cleaning method/ process [142] is as defined in the below description.
- FIG. 4 shows a flowchart of the self-regulated cleaning method/process [142] performed by the self-regulated cleaning system [104].
- the self-regulated cleaning method/process [142] initiates at step [144].
- the flush counter [126] continuously determines/ records the count of the number of flush actions performed on the face plate [116] of the flush tank [108] of the toilet arrangement [100].
- the float switches [136, 138] detect actuation of the face plate [116], corresponding to which the count of number of flushes are stored in the counter of the storage unit [140].
- the float switches [136, 138] detect actuation of the face plate [116] for either of the half flush action and the full flush action, based on the water remaining in the storage tank [110] after performing the flush action.
- the counter of the storage unit [140] is incremented.
- the storage unit [140] of the flush counter [126] stores the count of number of flush actions performed on the face plate [116] of the flush tank [108]. Thereafter, the self-regulated cleaning method/ process [142] proceeds to step [146].
- the control unit [132] retrieves the flush data, i.e. the count of the number of flush actions performed on the face plate [116] from the storage unit [140] of the flush counter [126], and compares the count of the number of flush actions with a predefined threshold value. In case, the count of the number of flush actions is smaller than the predefined threshold value, no action is taken. Particularly, the method moves back to step [144], in case the count of the number of flush actions is smaller than the predefined threshold value. In case, the count of the number of flush actions reaches beyond (is larger than) the predefined threshold value, the self-regulated cleaning method/ process proceeds to step [148].
- the flush data i.e. the count of the number of flush actions performed on the face plate [116] from the storage unit [140] of the flush counter [126]
- the control unit [132] activates the hydrogen peroxide generator [122] for a small period.
- the hydrogen peroxide generator [122] generates and releases hydrogen peroxide at a controlled flow rate and volume percentage (preferably 3 ⁇ 6 % volume of the storage tank [110]) in the storage tank [110] of the flush tank [108].
- the hydrogen peroxide generator [122] is deactivated.
- the self-regulated cleaning method/ process [142] proceeds to step [150]. With release of the hydrogen peroxide within water stored in the storage tank [110], the released hydrogen peroxide is then allowed to get mixed in the water stored in the storage tank [110] of the flush tank [108]. Thereafter, the cleaning process proceeds to step [152].
- the control unit [132] performs a first actuation of the flush valve [114] of the flush tank [108], for automatic flushing of the mixture of the hydrogen peroxide and water to the toilet bowl [106] of the toilet arrangement [102]. With such action, the mixture of the hydrogen peroxide and water is sprayed onto the dirt on the toilet bowl [106] of the toilet arrangement [102]. The hydrogen peroxide mixed water is allowed to settle on the toilet bowl, and thus act on dirt for a predefined time period. The predefined time period in the preferred embodiment is preferably 20 minutes. Thereafter, the self-regulated cleaning method/ process [142] proceeds to the step [154].
- the storage tank [110] of the flush tank [108] is filled with fresh water through the fill valve [112].
- the control unit [132] performs a second actuation of the flush valve [114] for flushing of the fresh water in the toilet bowl [106], for removal of dirt and hydrogen peroxide from the toilet bowl [106] of the toilet arrangement [102].
- the automatic cleaning of the toilet bowl [106] of the toilet arrangement [102] is performed.
- the control unit [132] clears the counter of the storage unit [140] of the flush counter [126], to zero the count of the number of flush actions.
- the self-regulated cleaning method/ process [142] restarts the count of the number of flush actions for next cycle of the steps of the self-regulated cleaning method/ process [142].
- the self-regulated cleaning system [104] performs automatic cleaning of the toilet bowl [106] of the toilet arrangement [102] by following the self-regulated cleaning method/ process [142], as the count of the number of flush actions performed on the face plate [116] reaches beyond the threshold value.
- the self-regulated cleaning system [104] performs automatic cleaning of the toilet bowl [106] of the toilet arrangement [102] by the self-regulated cleaning method/ process [142] after (10) flush actions.
- the self-regulated cleaning system [104] by following the self-regulated cleaning method/ process [142] enables automatic cleaning of the toilet bowl [106] of the toilet arrangement [102], a need for separate maintenance staff is avoided and thus the maintenance cost is substantially reduced. Also, timely and scheduled cleaning of the toilet bowl [106] of the toilet arrangement [102] enables increased life cycle of the toilet bowl [106] of the toilet arrangement [102].
- the hydrogen peroxide generator [122] As the hydrogen peroxide generator [122] is positioned within the storage tank [110], it has a protective shield of the storage tank [110]. Such protection of the hydrogen peroxide generator [122] within the storage tank [110] restricts exposure of the hydrogen peroxide generator [122] to external environment, thereby preventing degradation of electrodes contained therein by reacting with ambient air. This improves work life of the hydrogen peroxide generator [122].
- hydrogen peroxide is environment-friendly. Particularly, upon degradation of hydrogen peroxide, oxygen and water molecules are produced. Thus, usage of hydrogen peroxide is environment friendly in nature. Therefore, Hydrogen peroxide is a safe antimicrobial agent as per USFDA (United States Food and Drug Administration).
