DETAILED DISCLOSURE OF EMBODIMENTS

(10) Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with technology- or business-related constraints, which may vary from one implementation to another. Moreover, it will be appreciated that the effort of such a development might be complex and time-consuming but nevertheless would be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

(11) In accordance with some embodiments of the present invention, reference is now made to FIG. 1, showing a schematic block diagram of toilet cleaning system 10, in accordance with an embodiment of the present invention. Toilet cleaning system 10, shown in FIG. 1, comprises main control unit (MCU) 11, which is operationally connected to power source 12. Power source 12 is typically an electric battery or accumulator, whereas MCU 11 is typically an electronic device including a logic chip and/or computing device, such as computing device 400, shown in FIG. 7. Power source is optionally a DC transformer and/or electric connection to the power grid.

(12) MCU 11 typically comprises control panel and/or user interface 13, such as a graphical user interface (GUI). Control panel and/or user interface 13 typically include actuators, such as buttons, levers, knobs and/or a pedal and/or touchless activator sensors, configured for actuating system 10 and/or initiating a cleaning cycle of system 10. The actuators of control panel and/or user interface 13 in a non-limiting manner are configured for powering system 10 on/off, changing the cleaning modes of system 10, setting the values of oscillations and/or speed and/or various other parameters of system 10.

(13) Toilet cleaning system 10 further comprises geared electric motor 14, mounted on a robotic arm. Geared electric motor 14 is operationally connected to brush 16, configured for engaging in physical contact with the toilet bowl and exerting a robbing force onto the surface thereof.

(14) Toilet cleaning system 10 further comprises disinfectant and/or detergent module 17, is operationally associated with brush 16. Disinfectant and/or detergent module 17 comprises a reservoir (not shown) containing a disinfecting and/or detergent agent (henceforth a cleaning agent) and a controllable dispenser (not shown), operationally connected to and controlled by MCU 11. The controllable dispenser (not shown) of detergent module 17 is configured for discharging a predefined amount of the disinfecting and/or detergent agent onto the surface of the toilet, within proximity of brush 16.

(15) Toilet cleaning system 10 further comprises an encoder and/or sensor 15 connected to the haft of electric motor 14. Encoder and/or sensor 15 is configured for providing to MCU 11 data about a real time position and oscillation speed of the shaft of electric motor 14.

(16) Rotating brush 16 is preferably connected to electric motor 14 by a means of a flexible shaft (not shown) and provides control over distance and positioning, so as to sustain an effective reaching to and engaging with any point on the inner surface of the toilet bowl (not shown). Disinfectant and/or detergent module 17 comprises a fluids conduit associated with rotating brush 16.

(17) In accordance with some embodiments of the present invention, reference is now made to FIGS. 2 to 6, showing isometric views of toilet cleaning system 10, in various states of deployment, in accordance with an embodiment of the present invention. In a folded state, shown in FIG. 2, foldable arm 20, with rotating brush 16 (not shown) folded inside, contains geared motor 14 and encoder 15. Foldable arm 20 is pivotably mounted onto structural frame 22, which constitutes the structural frame of toilet cleaning system 10.

(18) Structural frame 22 is supported by pedestal 24. Structural frame 22 typically accommodates MCU 11 (not shown). Structural frame 22 includes actuation pedal 13. Pedestal 24 optionally accommodates electrical batteries and/or accumulators (not shown), in off-grid embodiments. Pedestal 24 is optionally attached to the floor by a means of mechanical connectors, e.g. bolts or rivets, or by a means of suction and/or adhesion, e.g. stickers or vacuum cups.

(19) In an unfolded state, shown in FIG. 3, foldable arm 20 is elevated relatively to structural frame 22. Pedestal 24, as can be seen in FIG. 3, optionally further accommodates reservoir 26 containing a disinfecting and/or detergent agent, as well as a controllable dispenser (not shown).

(20) In the commencement of the unfolded state, shown in FIG. 4, rotating brush 16 starts protruding from the distal end of foldable arm 20. In the conclusion of the unfolded state, shown in FIG. 5, rotating brush 16 is deployed and fully protrudes from foldable arm 20. As will be elaborated hereunder, in a completely deployed and/or unfolded state, rotating brush 16 assumes a substantial size, occupying essentially the entire inner lumen of a toilet bowl, of a toilet; whereas in a completely folded state, rotating brush 16 is fully accommodated within foldable arm 20.

(21) With reference to FIG. 6, in the completely unfolded and deployed state, rotating brush 16 is fully deployed from foldable arm 20, so that the bristles of rotating brush 16 effectively reach to and engage with any point on the inner surface of the toilet bowl, of toilet 30. During the operation controllable dispenser (not shown) discharges disinfecting and/or detergent agent from reservoir 26 onto the surface of the bowl of toilet 30, to achieve a combined operation of mechanical and chemical cleansing.

(22) Moreover, during the operation, encoder and/or sensor 15 continuously counts the revolutions of the haft of electric motor 14. Having the rotational torque of electric motor 14 and/or idle number of revolutions per minute for electric motor 14 known, rotating brush 16 is preferably urged against the inner surface of the toilet bowl, of toilet 30, until encoder and/or sensor 15 detects the reduction in rotational speed to a predefined value, thereby ensuring effective mechanical rubbing of the bristles of rotating brush 16 against the inner surface of the toilet bowl, of toilet 30.

(23) With reference to FIG. 7, an exemplary computing device for implementing MCU 11 described herein includes computing device 400. In its most basic configuration, computing device 400 typically includes at least one processing unit 402 and memory 404.

(25) Computing device 400 typically includes a variety of computer readable media. Computer readable media can be any available media that can be accessed by computing device 400 and include both volatile and non-volatile media, and removable and non-removable media. Computer storage media include volatile and non-volatile, and removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Memory 404, removable storage 408, and non-removable storage 410 are all examples of computer storage media. Computer storage media include, but are not limited to, RAM, ROM, electrically erasable program read-only memory (EEPROM), flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by computing device 400. Any such computer storage media may be part of computing device 400.
