[0001] This application claims the priority of Indian Application No. 202411094189, filed on November 30, 2024, and incorporates it by reference. Technical Field

[0002] This disclosure relates to toilets, and more particularly to toilets with low water consumption during flushing cycles. More specifically, it relates to a piston-operated flushing mechanism for a toilet. Background Technology

[0003] This section is intended to provide information relating to the field of the invention, and therefore should not be construed as prior art simply because any method or function described below is included in this section.

[0004] Conventional toilets use a large amount of water with each flush, at least 3 liters, making water consumption patterns strained and causing environmental problems. This high water volume usage is associated with the water-intensive process of transporting waste through the sewer. Some existing solutions suggest using alternating flush patterns that require less water, but this may not guarantee a water seal in case of malfunction. Summary of the Invention

[0005] This section is intended to present some of the objectives of the disclosed methods and systems in a simplified form, rather than to identify key advantages or features of this disclosure.

[0006] One objective of this invention is to provide a piston-type flushing toilet that uses a minimum volume of water during the flushing cycle instead of a conventional flushing mechanism.

[0007] Another objective of the present invention is to provide a piston-type flush toilet including a piston mechanism to effectively eliminate waste through the toilet's drain passage.

[0008] Another objective of the present invention is to provide a piston-type flush toilet including a mouth-shaped valve, which serves as a seal between the basin and the piston mechanism to prevent leakage of water or waste.

[0009] Another objective of the present invention is to provide a piston-type flush toilet that includes a water tank that automatically maintains a water seal even during a failure of the main valve, thereby ensuring the use of eco-friendly water for odor control and effective waste removal.

[0037] In the following description, various specific details are set forth for purposes of explanation to provide a thorough understanding of embodiments of the present disclosure. However, it will be apparent that these embodiments can be practiced without these specific details. The features described below can be used independently of each other or in any combination with other features. Individual features may not solve any of the problems discussed above, or may only solve one of the problems discussed above. Some of the problems discussed above may not be fully solved by any of the features described herein. Exemplary embodiments are described below as illustrated in the accompanying drawings, wherein similar reference numerals refer to the same parts in different drawings.

[0038] This disclosure proposes to address this drawback by introducing a toilet with a piston mechanism that uses only minimal water for flushing and introduces a backup water seal through a reservoir. This disclosure proposes a significant reduction in water consumption without compromising performance and meeting all specifications and standards, and represents a sustainable solution for modern sanitation needs.

[0039] Embodiments of this disclosure relate to piston-type flush toilets, replacing conventional flushing mechanisms with piston-driven flushing mechanisms that provide an effective flushing cycle with minimal water usage.

[0040] In a preferred embodiment, the actuation power of a piston mechanism is used to efficiently remove waste, while each flush utilizes only about one liter of water. By significantly reducing water consumption without compromising performance, and by meeting all specifications and standards, this embodiment provides a sustainable solution to existing sanitation needs. For effective flushing cycles, the prescribed standard is to maintain a water seal depth of approximately 2.07 inches. Other water seal depths can be used.

[0041] In a preferred embodiment, the water tank is configured to automatically maintain a water seal even if the main valve fails, thereby ensuring the use of eco-friendly water for odor control and effective waste removal.

[0042] The following embodiments relate to toilets and related systems. One or more related systems can also be applied to any plumbing fixture. The term "plumbing fixture" refers to a device that is connected to a plumbing system of a house, building, or other structure. The term "plumbing fixture" can include toilets, bidets, faucets, shower heads, bathtubs, urinals, and dishwashers. For each of the exemplary toilets described herein, it should be noted that the shape and configuration of the tank, base, seat assembly, and internal components (including the drain passage and other features) may differ from the embodiments shown and described herein, and the embodiments disclosed herein are not intended to be limiting. It should be noted that the various components of the toilet can be made of vitrified ceramic. It should be noted that the various components of the toilet can be polymerized and / or molded or otherwise fixed to the toilet. For example, it should be noted that although the toilet shown in the exemplary embodiments is configured with the tank formed separately from the base, and the tank subsequently attached to the base, as a one-piece design, the tank can be integrally formed with the base. In other words, the toilet can be a one-piece design, a two-piece design, or have any suitable configuration. The toilets disclosed herein can have a wide variety of skirted toilet configurations, all of which are intended to be covered herein. Therefore, the following description of various toilet features is intended to illustrate only one possible embodiment, and the reader of this specification should understand that similar concepts or features may be included in other various embodiments.

[0043] Figure 1 A piston-type flushing system according to an embodiment is disclosed. It discloses a piston-type flushing toilet 10 including a toilet bowl 101 having a rim 102 for supplying flushing water to the bowl 101 via a primary water source supplied to the toilet 10. A water tank 103 is provided, connected to the toilet bowl 101 by a sump jet or refill pipe 104. The water tank 103 serves as a secondary water source for supplying water to the toilet 10. Additional, different, or fewer components may be included.

[0044] A port-shaped valve 105 is further disclosed, which serves as a seal for the toilet bowl 101. The drain passage of the piston-type flush toilet 10 is a modified structure, comprising an angled, upwardly positioned upper drain support cylinder 107, wherein the port-shaped valve 105 serves as the inlet of the upper drain support cylinder 107. The upper drain support cylinder 107 and the drain passage 109 are connected by a curved drain passage connector 108, which facilitates easy emptying of the contents of the bowl 101. In any of the disclosed examples, the cylinder 107 may have a volume or capacity of approximately 0.5 to 2.0 liters. Other sizes may be used.

[0045] In a preferred embodiment, the orifice valve 105, the drain upper support leg cylinder 107, and the drain channel 109 are made of plastic. Preferably, the orifice valve 105 is made of polyvinyl chloride (PVC), wherein the seal is made of nitrile rubber and the gate is made of glass fiber reinforced polypropylene. Further, in a preferred embodiment, the drain upper support leg cylinder 107 is made of extruded PVC. Further, in a preferred embodiment, the drain channel 109 is made of a plastic selected from PP 20GF or PVC.

[0046] In a preferred embodiment, the upper outrigger cylinder 107 is manufactured by extrusion molding. The curved drain channel connector 108 is manufactured by injection molding. During assembly, the two components can be joined by a process (e.g., ultrasonic welding or rotary welding). The manufacturing and joining methods are exemplary methods identified for the purposes of this disclosure and are not intended to limit other methods to be implemented.

[0047] Cylinder 107 is a tubular structure configured to contain a piston assembly within itself, and it acts as a conduit to transfer water and waste contents from basin 101 via drain passage 109 to outlet 110. At the start of a flushing cycle, piston 106 is positioned at the lower end of cylinder 107, and piston 106 is actuated when the user initiates a flushing cycle after using toilet 10.

[0048] Actuator 150 can be configured to initiate a flushing sequence or flushing cycle of toilet 10. Actuator 150 can be an electronic button that actuates orifice valve 105 and / or piston 106. In either case of orifice valve 105 and piston 106, a solenoid can be electronically driven in response to actuator 150. In some examples, actuator 150 can be located on a power circuit having orifice valve 105 and / or piston 106, such that pressing the actuator completes the power circuit to deliver power to orifice valve 105 and / or piston 106. In other examples, actuator 150 can send an electrical signal to a controller (e.g., controller 100 described below), and the controller then activates orifice valve 105 and / or piston 106. An exemplary actuator 150 of controller 100 as a user input device 355 is described below.

[0049] In another alternative, actuator 150 may be a handle (e.g., a flush lever) connected to a mechanical drive system that causes one or more components of the piston-type toilet 10 to move in order to operate the flush. Actuator 150 may be connected to a rod or bar that operates the orifice valve 105 and / or the piston 106.

[0050] Additionally, actuator 150 can be configured to operate one or more pumps. The pumps can pump water from reservoir 103 to toilet bowl 101 according to a set duration or volume as described herein.

[0051] Additionally, actuator 150 can be configured to operate one or more valves. For example, a valve can open the supply of flushing or cleaning water from the facility to edge 102.

[0052] While not every embodiment describes an actuator for initiating a flushing cycle, all examples herein may include an actuator or another type of flushing mechanism, such as a button configured to be activated upon being pressed (or pulled) a predetermined distance or upon being touched, a lever configured to be activated upon rotation of a predetermined angular distance, or any suitable device configured to be activated based on user input. Any of the embodiments described regarding the toilet and / or the toilet's drain path can be applied to the structure of a urinal.

[0053] Additionally or alternatively, the toilet 10 may include a sensor S. As described below, the sensor (e.g., sensor 356) may detect the presence of a user, a user's gesture, the condition of the contents in the basin 101, or the environmental conditions near the toilet 10. The sensor S may generate sensor data, which serves as input to a controller (e.g., controller 100 described below), which in turn activates the orifice valve 105 and / or the piston 106.

[0054] In the discussion of each embodiment, the seat and lid may sometimes be omitted. However, each of the following examples may include a toilet seat assembly comprising a lid member (e.g., a cover), a seat member (e.g., a ring member), and a hinge. The seat member may be configured to include a ring member surrounding an opening, wherein the ring member provides a seat surface for the user of the toilet. The seat member may also be pivotally coupled (e.g., attached) to the hinge, wherein the seat member may rotate (or pivot) about the hinge, for example, between a first lowered or seated position and a second raised or upright position. The lid member may be configured to be circular, elliptical, or any other suitable shape. Typically, the profile or shape of the outer surface of the lid member will be configured to match (i.e., substantially similar to) the profile of the outer surface of the seat member to improve the aesthetics of the seat assembly and the toilet. The lid member may also be coupled to the hinge, wherein the lid member may rotate (or pivot) about the hinge, for example, between a first lowered or lowered position and a second raised or upright position. When in the downward position, the cover member can be positioned above the seat ring member to cover the opening of the seat ring member and conceal the inside of the basin 101. When the cover member is in the upright position, it can be configured to rest against the outer surface of the tank, thus maintaining the upright position for the user to sit on the seat ring member.

[0055] refer to Figure 2 It discloses a toilet 10 in a flushing first state or in an unflushed or unused state (such as...). Figure 7 (As indicated in Operation / State S1). In this state, basin 101 is configured to hold a predetermined amount of water (e.g., about 0.5 liters), and during this state, orifice valve 105 remains closed. The water level 112 in basin 101 is maintained or sealed by orifice valve 105, which prevents water leakage into cylinder 107.

[0056] refer to Figure 3 It discloses the second state of being flushed (such as...) Figure 7 The toilet 10 is in the action / state S2 indicated or in the post-use state, where the user activates the flushing mechanism after defecation or urination. Upon initiation of flushing, a predetermined volume of water (e.g., approximately 0.4 liters) is released into the toilet bowl 101 via the edge jet 102 or a first water source. This influx of water is used to clean the surface of the toilet bowl 101 before it finally flows into the sump.

[0057] In this state, the orifice valve 105 remains sealed or closed to prevent the contents of the basin from leaking into the cylinder 107. Similarly, the piston 106 is in its retracted or original state (as in the unused state S1).

[0058] refer to Figure 4 The document discloses a toilet 10 in a third flushing state (as indicated in Action / State S3). In this state, once the basin is cleaned and water flows down into the sump of the toilet bowl 101, the orifice valve 105 is unlocked, directing all water and waste into the upper support cylinder 107. Furthermore, to ensure proper cleaning or removal of the contents of the toilet bowl 101, additional water (e.g., approximately 0.1 liters) is introduced into the cylinder 107 via the sump pipe 104 and the sump jetter.

[0059] During this process, the orifice valve 105 remains in its retracted position. However, the piston remains in its original state, i.e., its state / action S1.

[0060] refer to Figure 5 The toilet 10 is disclosed in the fourth flushing state (i.e., as indicated in action / state S4). After additional water flows from the reservoir 103 into the cylinder 107 through the sump jet or sump pipe 104, the orifice valve 105 returns to its initial or closed position. After the orifice valve 105 has closed, the piston 106 moves upward in the cylinder 107 to the open state 113, pushing water and waste upward from the cylinder 107 and into the plastic drain passage 109, from which it is discharged through the outlet 110.

[0061] refer to Figure 6The toilet 10 is in the fifth flushing state (as indicated in Action / State S5). In this state, after waste is discharged, the piston 106 retracts to its original position, and the orifice valve 105 is also in the closed position. The water tank 103 can then dispense an initial amount (e.g., approximately 0.7 liters of water) into the sump of the toilet bowl 101. When the desired water level 112 is reached in the bowl 101, the toilet 10 is considered ready for the next use and flushing cycle.

[0062] In a preferred embodiment, the piston is operated by a water-driven telescopic cylinder. However, the piston 106 is capable of various activation methods, such as manually operated cylinders, hydraulic cylinders, cable-operated cylinders, pneumatic cylinders, and electric actuators. These alternative devices and methods can be implemented in alternative embodiments of this disclosure without departing from the scope of use of the piston 106.

[0063] Figure 7 The diagram shows... Figures 2 to 6 The flowchart illustrates the process for flushing a piston-type toilet, from the first to the fifth state. It may include additional, different, or fewer actions.

[0064] As if Figures 2 to 6 The flushing cycle, as described by the flushing actions / states S1 to S5, represents one cycle of use and flushing in the piston-type flush toilet 10 according to a preferred embodiment. This disclosure uses less water compared to existing toilets. In some examples, only 0.9 liters or less of water is used per flushing cycle.

[0065] At action / state S1, water is supplied to the toilet bowl 101. Water can be supplied from a water supply (e.g., line pressure of a water supply facility), and the water can be metered (e.g., measured) by a valve and timer (as implemented by controller 100). Alternatively, water can be supplied from a water tank, which can also be metered (e.g., measured) by a valve and timer (as implemented by controller 100). In yet another example, water can be supplied by one or more edge nozzles.

[0066] While or after water is supplied to the basin 101, the orifice valve 105 is closed to seal the toilet basin 101 with the cylinder 107.

[0067] In action / state S2, activation is received from the flushing mechanism. The flushing mechanism can be an actuator 150 (e.g., a button or lever). The flushing mechanism can generate an electrical signal that is provided to the controller 100, or otherwise directly actuate the valve to clean the sides of the basin 101.

[0068] Water can be supplied as cleaning water from a rim nozzle, which flows downwards along the side of the toilet bowl 101. The rim nozzle can be a single nozzle that releases water into a rim channel. The water gradually cleans the sides of the bowl along the rim channel using an oscillating motion or vortex. Alternatively, multiple rim nozzles can be arranged around the circumference of the toilet bowl 101.

[0069] In action / state S3, the orifice valve 105 opens to release contents from the toilet bowl 101 into the piston cylinder 107. The contents of the bowl may include flushing water and feces or urine excreted by the user. The flushing mechanism may generate an electrical signal that is provided to the controller 100, or otherwise directly operate the orifice valve 105.

[0070] In action / state S4, piston 106 is propelled. The propelling of piston 106 can be based on any example described herein (e.g., telescopic cylinder, magnetic drive, worm gear drive, linear actuator). The flushing mechanism can generate an electrical signal that is provided to controller 100, or otherwise directly operate piston 106. The propelling of piston 106 pushes the contents from basin 101 through cylinder 107 and into the drain passage. In some examples, the drain passage can be omitted, and the contents are pushed directly into the drain or outlet.

[0071] The delay can be implemented by the controller 100 or by the actuator 150, such that a predetermined time elapses between the opening of the orifice valve 105 and the advancement of the piston 106.

[0072] Additionally, during or after action / state S4, the orifice valve 105 is closed.

[0073] In action / state S5, piston 106 retracts. That is, the controller 100 or a series of signals from the flushing mechanism causes piston 106 to reverse its direction and move downward toward its original seated position.

[0074] Additionally, during or after action / state S5, an indicator may indicate that the flushing cycle has been completed. The controller 100 may also provide instructions or commands to one or more indicators. Indicators may include lights, displays, audio transmitters or speakers, LEDs, or other devices configured to convey the status of the toilet 10. The process may return to action / state S1 to reset the toilet 10.

[0075] Based on the aforementioned flushing cycle, this disclosure relates to the use of two water sources: a primary water source released through edge 102 and a secondary water source, or a water storage tank 103 that releases water through a sump jet 104. The water storage tank 103 or the secondary water source is a water tank or storage structure installed on the side of the toilet 10.

[0076] Figure 8 and 9 The illustration shows a water tank 103 attached to the basin at the sump jetter 104 via a hose or pipe. The water tank 103 can be a customizable, variable-size plastic structure. The water tank 103 can be manufactured using a blow molding process, or it can be integrated into the toilet basin 101 using a drainage casting process. In one embodiment, a hose is used to connect the water tank 103 to the toilet basin 101.

[0077] In a preferred embodiment, the water tank 103 is customized to hold a certain volume of water, and the specifications of the water tank 103 can be designed to support that volume.

[0078] In an exemplary embodiment, the water tank 103 can be configured to hold a water volume of 5 liters.

[0079] The water storage tank 103 is directly connected to a water supply device (e.g., a pipe fastener connected to the water supply device under line pressure), and the water storage tank 103 includes a filling valve attached to a float 114. The position of the float 114 in the initial or unfilled stage of the water storage tank 103 is determined by its position... Figure 9 Position P1 is indicated. Water enters the water storage tank 103 through inlet 111, and float 114 rises, causing the water level in tank 103 to rise simultaneously. When the desired water level is reached (e.g., Figure 10 When the valve is in position P2 (as shown in the diagram), it closes and prevents water from entering the water tank 103 further.

[0080] refer to Figure 11 When the water tank 103 reaches the filling position P2, the water level 115 in the tank and the water level 112 in the basin are similar (i.e., the water levels are at the same position).

[0081] The water tank 103 is also connected to the basin 101 via a sump jet 104. When the water tank 103 is filled with water, the basin 101 is correspondingly filled with water by the sump jet 104. At the end of the water intake cycle, the water levels 112 and 115 are at the same position, indicating that the basin 101 is operating in accordance with the usage and flushing cycle.

[0082] refer to Figure 12The invention discloses an operating mechanism for the toilet 10 in the event of a malfunction of the orifice valve 105. In an exemplary embodiment, if the orifice valve fails to close or malfunctions, the water tank 103 begins to release water into the basin 101 to fill the upper support cylinder 107 until it reaches the same level as the water level in the basin. This process occurs naturally and requires no additional valves or mechanical devices. This mechanism ensures that the seal depth remains within the basin, preventing any improper release of sewer gas from the outlet 110 through the drain passage 109 and into the basin 101.

[0083] In another exemplary embodiment, in the event of a failure of the edge inlet water system, the water tank will function in a similar manner to fill cylinder 107.

[0084] refer to Figure 13 The invention discloses an alternative embodiment of the piston mechanism. It discloses a spring-actuated mechanism, wherein the actuation mechanism is driven by a spring 1061, which moves a piston 106. A cable or belt 1062 is used to compress the spring during the actuation process. As an alternative implementation, the cable / belt can be wound with a cable reel 1064 connected to an electric motor or manual lever 1063 to provide compression to the spring.

[0085] Figure 14 An exemplary water-driven piston flushing toilet 200 is illustrated, and Figure 15 A more detailed view of the water-driven cylinder 210 incorporated in a water-driven piston flushing toilet 200 is illustrated. The water-driven piston flushing toilet 200 can be housed within a housing or frame housing 20. The water-driven piston flushing toilet 200 includes a toilet bowl 101, a rim 102, a water tank 103, a refill tube 104, a port valve 105, a drain passage connector 108 (e.g., a drain passage connection joint), a drain passage 109, an outlet 110, a port valve housing with a cavity 121, a flange 122, a cylinder inlet hose 124, a water tank 125 (e.g., a lower tank), and a storage pump 126 (e.g., a lower pump). Additional, different, or fewer components may be included. The description of similar components herein can be applied to the water-driven piston flushing toilet 200.

[0086] The water-driven cylinder 210 includes a piston 106, a housing 130, an outer cylinder 131, an inner cylinder 132, a drain upper support leg cylinder 133, a cylinder housing flange 134, and a cylinder inlet 135. The cylinder housing flange 134 supports the drain upper support leg cylinder 133 to support the cylinder housing. The top of the cylinder is connected to a drain channel 109 via a drain channel connector 108, which guides waste through the drain channel 108 from the water-driven piston flush toilet 200 and directs waste through an outlet 110 into a sanitary path. The sanitary path can provide a partially pressure-driven and partially gravity-driven path to a sewer or septic tank system. The sanitary path can also be connected to greywater or water treatment equipment. Additional, different, or fewer components may be included.

[0087] The external frame of the water-driven cylinder 210 may include two parts: a housing 130 and a drain upper support leg cylinder 133. When the water-driven cylinder 210 is in standby mode (i.e., no flushing operation is being performed), the housing 130 may surround the lower half or lower proportional region of the water-driven cylinder 210, with the outer cylinder 131, inner cylinder 132, and piston 106 nested or overlapping each other in the lower half or lower proportional region of the water-driven cylinder 210. The housing 130 may be molded from plastic or other synthetic materials. The drain upper support leg cylinder 133 may surround the upper half or upper proportional region of the water-driven cylinder 210, and when the water-driven cylinder 210 is in flushing operation, the outer cylinder 131, inner cylinder 132, and piston 106 extend into the upper half or upper proportional region of the water-driven cylinder 210.

[0088] The movable part of the water-driven cylinder 210 operates in three stages. First, the outer cylinder 131 moves upward. In the second stage, the inner cylinder 132 follows. In the third stage, once the outer cylinder 131 and the inner cylinder 132 have reached their full stroke length, the piston 106 is activated and pushes waste and water out of the cylinder.

[0089] The housing 130 can form a water chamber. The water chamber can be connected to a water tank 125 via a cylinder inlet hose 124. A pump 126 is configured to pump water from the water tank 125 to the water chamber at the cylinder inlet 135 via the cylinder inlet hose 124. When the water chamber is filled, force is applied to the inner cylinder 132, the outer cylinder 131, and the piston 106 to advance the wastewater discharge upper support leg cylinder 133. The wastewater discharge upper support leg cylinder 133 can have a capacity of approximately 1.5 to 1.6 liters, corresponding to approximately 1 liter of water and approximately 500-600 grams of waste.

[0090] The operation of pump 126 can also be reversed. Pump 126 can be operated in the opposite direction to pull or draw water from cylinder inlet 135 into water tank 125 through cylinder inlet hose 124, while cylinder inlet 135 draws water from inside housing 130 to pull inner cylinder 132, outer cylinder 131 and piston 106 from the extended position back to or towards their original positions in housing 130.

[0091] In this way, the water-driven cylinder 210 and water tank 125 can be reused or recycled with the same water through multiple or many flushing operations.

[0092] The inner cylinder 132, outer cylinder 131, and piston 106 may include seals (e.g., O-rings) to minimize or prevent water leakage. Any combination of joints between components, or at least moving components, may include seals.

[0093] In some cases, leaks may occur from the water-driven cylinder 210 and / or the water tank 125. Leaks may occur during installation when the water-driven piston-type flush toilet 200 is placed at an angle or on its side. Leaks may also occur when seals or O-rings wear, shift, or need replacement. In such cases, the water tank 125 can be refilled to a predetermined level. Refilling can be performed automatically by opening a valve to the water supply system to add water to the water tank 125 at the refill port 141. Manual refilling of the water supply system can also be performed via a manual valve. Refilling can also be done manually by pouring water into the refill port 141 on the water tank 125.

[0094] A fluid other than water can be used. Therefore, the water chamber can be any type of hydraulic chamber. The hydraulic fluid can be kept under pressure. According to Pascal's law, the force exerted by the force generated by the hydraulic fluid is proportional to the displacement of the hydraulic fluid flowing from the reservoir 125 into the hydraulic chamber. One or more valves can be actuated in the hydraulic circuit to facilitate hydraulic operation, causing the piston 106 and the cooperating cylinder to rise into the drain upper outrigger cylinder 133. Replacement hydraulic fluid can also be added automatically or manually via the refill port 141.

[0095] Figure 16 The diagram illustrates the rinsing sequence. Figures 17 to 21The flowchart describes the first action / state through the fifth action / state. Additional, different, or fewer actions / states may be included. Controller 100 may send control signals to any of the pumps, valves, motors, or solenoids described herein to facilitate the flushing sequence of said actions / states. As described above, the flushing sequence can be triggered by actuator 150 (e.g., a button), sensor S (e.g., user presence or gesture / footwork), or wireless communication with a remote control or mobile device.

[0096] Figure 17 The illustration shows a water-driven piston-type flushing toilet 200 in the first flushing state or in the unflushed or unused state S11. Figure 17 The water-driven piston-type flushing toilet 200 can be considered to be in a standby or ready state. A predetermined amount of water has been filled into the toilet bowl 101. The orifice valve 105 is closed to maintain a seal between the toilet bowl 1101 and the water-driven cylinder 210.

[0097] The orifice valve 105 may include a plate or disc that selectively moves into and out of an opening located between the toilet bowl 101 and the water-driven cylinder 210. The plate of the orifice valve 105 can be operated via a solenoid selectively energized by the controller 100 or directly via the actuator 150. The solenoid can push or pull the plate into the cavity 121. In another example, the plate is spring-loaded (e.g., normally open), such that the spring biases the plate away from the opening, but a latch holds the orifice valve 105 in a retracted position to cover the opening. The latch can be released via the controller 100 or directly via the actuator 150, causing the spring to open the orifice valve 105. When the plate is in the cavity 121, the orifice valve 105 has opened the opening between the toilet bowl 101 and the water-driven cylinder 210. When the plate is outside the cavity 121, the orifice valve 105 has closed the opening between the toilet bowl 101 and the water-driven cylinder 210.

[0098] As part of the first action / state S11 Figure 17 Water can be loaded into the toilet bowl 101 via the reservoir 103 and the refill passage 104. Alternatively, the end of the flushing sequence can refill water from the reservoir 103 into the toilet bowl 101 to place the water-driven piston-flush toilet 200 into a ready or standby state. The amount of water used for the ready or standby state can be referred to as a first predetermined amount, which may be, for example, about 0.5 liters.

[0099] Figure 18A This is a front view of a water-driven piston-type flushing toilet 200 in the second flushing action / state S12, in which a side jet provides water to clean the toilet bowl 101. Figure 18B yes Figure 18A The magnified portion, illustrated, shows what's hidden within Figure 18A Details are shown in the view. Edge jet water can be supplied from the water tank 103 via a pump 142 through an edge jet pipe 143, which connects to the edge passage of the toilet bowl at an edge jet inlet 144. The toilet bowl 101 can be integrally formed with the edge 102 to form an edge jet passage around the circumference of the toilet bowl 101 (as indicated by the arrow in Figure 18), which supplies flushing water to clean the toilet bowl 101 during a flushing operation. The amount of water used for edge cleaning can be referred to as a second predetermined amount, which may be, for example, about 0.4 liters.

[0100] Figure 19 This is a front view of a water-driven piston-type flushing toilet 200 in the third action / state S13 of flushing. The orifice valve 105 is open. As described above, the orifice valve 105 can be opened by opening the latch, which releases the orifice valve 105 into the chamber 121 under the biasing force from the spring. Alternatively, the orifice valve 105 can be moved via a solenoid.

[0101] Additional water can be introduced into the toilet bowl 101 via a sump jet. For example, a pump 142 of the reservoir 103 can pump water to the sump jet or pipe 104. Pump 142 can be operated by controller 100 or directly from actuator 150 to supply water to the sump jet or pipe 104. Pump 142 may include a separately operating chamber to distinguish between the sump jet and the edge jet. In another example, separate pumps can be used for both the sump jet and the edge jet. The additional sump water volume can be referred to as a third predetermined amount, which may be, for example, about 0.1 liters.

[0102] Figure 20 This is a front view of a water-driven piston-type flushing toilet 200 in the fourth action / state S14 of flushing. In this state, the piston 106 is moved to travel upward in the cylinder assembly from its initial position to the open state, so as to flush the contents from the toilet bowl 101 through the cylinder assembly, which will be discharged through the drain passage 1009 and the outlet 110.

[0103] As described above, piston 106 can be operated by a water-driven cylinder 210. That is, water can be pumped into the cylinder to push piston 106 upwards and move water and waste into drain channel 109. In this example, multiple sleeves or cylinders of different diameters can be fitted together such that when subjected to pressure, they overlap and extend outwards. The telescopic cylinder can have any number of segments (e.g., three or more segments). Other actuation techniques for piston 106 are described below.

[0104] Figure 21 This is a front view of a water-driven piston-type flushing toilet 200 in the fifth action / state S15 of flushing. In this action, the piston 106 retracts. For the water-driven cylinder 210, water is removed from the cylinder to pull the piston 106 or retract it. Other actuation techniques for the piston 106 are described below.

[0105] Optionally, the action may also include distributing a first predetermined amount of water into the sump of the toilet bowl 101 to put the water-driven piston flush toilet 200 into a ready state.

[0106] Figure 22 An exemplary spring-actuated embodiment of a water-driven piston-type flushing toilet 200 is illustrated, which includes a cylinder 167, a spring 160, a belt or cable 161, a winder 163, and a motor 162. The spring-actuated system is an alternative to a water-driven cylinder. Additional, different, or fewer components may be included.

[0107] In the standby or ready state, piston 106 rests at the bottom of cylinder 167. Spring 160 is compressed and stores potential energy, which can be used to push piston 106 through cylinder 167, so that waste and water move from basin 101 through cylinder 167 toward drain channel 109, which empties into outlet 110.

[0108] The release mechanism, which releases spring 160 to push piston 106 through cylinder 167, can be executed by releasing cable winder 163. A command is sent from controller 100 or directly via actuator 150 to cable winder 163 to open during flushing, releasing the spring to push piston 106 toward drain channel 109. When flushing begins, winder 163 is triggered and releases cable 161, which holds spring 160 in a compressed state. As tension is released, spring 160 pushes piston 106 upward, forcing waste and water through and out of cylinder. Winder 163 may include a ratchet mechanism (e.g., a one-way mechanism) that helps release and lock spring 160 in its compressed position, ensuring smooth and controlled operation.

[0109] These actions can be replaced by the fourth action / state S14 above. In other words, the operation of the water supply device and the orifice valve 105 can remain unchanged.

[0110] After rinsing or at the end of a rinsing sequence, spring 160 is reset using motor 162 and winder 163 (one-way cable winder). A command is sent from controller 100 or directly via actuator 150 to motor 162 to operate the winder, causing cable 161 to retract, compressing spring 160 and storing energy for subsequent rinsing. To return piston 106 downward, motor 162 again rotates winder 163. This winds the belt or cable 161 back, pulling piston 106 downward and simultaneously compressing spring 160. Once spring 160 is fully compressed, motor 162 stops, and winder 163 locks in place to hold spring 160. Alternatively, a manual operating handle or lever can be used to wind cable 161 and compress or reset spring 160.

[0111] Figure 23A The diagram illustrates a worm gear piston activator for driving piston 106. The worm gear piston activator may include a motor 170, a drive wheel 171, a worm gear 172, and a worm gear 173. Additional, different, or fewer components may be included.

[0112] Motor 170 can be a servo motor commanded by controller 100 to operate at certain positions or in certain directions. Operation of motor 170 causes worm gear 173 to rotate. Worm gear 173 meshes with one or more worm wheels 172. Worm wheels 172 can be spur gears or cylindrical gears. The worm gear 173 is linked to the worm wheels 172, which change their direction of rotation—from horizontal to vertical. Therefore, when motor 170 rotates, it causes worm gear 173 to rotate, and then worm gear 173 causes worm wheels 172 to rotate.

[0113] The worm gear 172 operates the drive wheel 171, which causes the cylinder 107 to move internally. The worm gear 172 may be engaged with or otherwise connected to the drive wheel 171. When the worm gear 172 rotates, it also causes the drive wheel 171 to rotate. The drive wheel 171 contacts the inner surface of the cylinder 107 and causes the piston 106 to move up and down.

[0114] The drive wheel 171, worm gear 172, and / or worm gear 173 can be supported by and mounted on the cylinder 107. The cylinder 107 may include two worm gears 172 and a drive wheel 171 on opposite sides. Other numbers of worm gears 172 and drive wheels 171 can be used. The worm gear piston activator is a drive system supported by the cylinder 107.

[0115] In one example, when motor 170 rotates clockwise, drive wheel 171 pushes piston 106 upward. When motor 170 rotates counterclockwise, piston 106 moves downward. This movement is used to push waste and water out of cylinder 107 and into drain channel 109 during flushing, and then subsequently returns piston 106 to its original position.

[0116] In idle state, piston 106 remains at the bottom of cylinder 107. Inside piston 106, motor 170 can be connected to worm gear 173. Commands are sent from controller 100 or directly via actuator 150 to motor 170 to push piston 106 toward drain channel 109 during flushing. These actions can be replaced by the fourth action / state S14 above. In other words, the operation of water supply device and orifice valve 105 can remain unchanged.

[0117] After rinsing, or at the end of the rinsing sequence, the controller 100 or directly via the actuator 150 sends a command to reverse the motor 170 to pull the piston 106.

[0118] Figure 23B The illustration shows a cylinder 107 (magnetically coupled rodless cylinder) magnetically coupled to a drive mechanism. The drive mechanism includes a motor 170, a coupling (drive system) 181, a lead screw 182, a lead nut 183, and a drive magnet 184 aligned with the driven magnet 185 of the piston 106. Additional, different, or fewer components may be included.

[0119] Driven magnet 185 is mounted to piston 106 and can be secured with adhesive or fasteners. Driven magnet 185 may be a neodymium magnet. Driven magnet 184 may be mounted to guide nut 183 and can be secured with adhesive or fasteners. Driven magnet 185 may be a neodymium magnet. Other types of magnets may be used for driven magnet 185 and / or drive magnet 195.

[0120] The two magnets can be magnetically connected to each other, meaning that the magnets can move together without direct contact. When the guide nut 183 moves upward, the piston 106 follows due to this magnetic connection.

[0121] A guide nut 183 is mounted on a guide screw 182. The guide nut 183 may include an internal thread that mates with the guide screw 182. When the guide screw 182 rotates in one direction (e.g., clockwise), the guide nut 183 moves upward, causing the piston 106 to move in a direction that flushes or propels water and waste through the cylinder 107 to the drain passage 109. When the guide screw rotates in another direction (e.g., counterclockwise), the guide nut 182 moves downward, causing the piston 106 to return to its original position.

[0122] Motor 170 drives lead screw 182 and can rotate lead screw 182 in both directions as needed. Motor 170 is connected to lead screw 182 via drive system 181 or coupling. Drive system 181 may include one or more gears that establish a gear ratio or torque ratio such that motor 170, rotating at a first speed (faster), causes lead screw 182 to rotate at a second speed (slower).

[0123] In standby mode, piston 106 remains in its original position at the bottom of cylinder 107. When flushing begins, motor 170 rotates guide screw 182 in a first direction. This causes guide nut 183 to move upward, and piston 106 moves accordingly, thereby pushing waste and water out of cylinder 107. A command is sent from controller 100 or directly via actuator 150 to motor 170 to push piston 106 toward drain channel 109 during flushing. These actions can be replaced by the fourth action / state S14 above. In other words, the operation of the water supply device and orifice valve 105 can remain unchanged.

[0124] After rinsing, or at the end of the rinsing sequence, controller 100 or directly via actuator 150 sends a command to reverse motor 170 to pull piston 106. To return piston 106 to its original position, motor 170 causes lead screw 182 to rotate in the opposite direction, causing lead nut 183 and piston 106 to return downwards.

[0125] Figure 24A The diagram illustrates a cable activator. In this embodiment, a lead screw mechanism is used to drive a cable and pulley system instead of a magnet to drive the piston 106. The cable activator includes a first pulley 191, a second pulley 192, and a cable 193 held tightly between the first pulley 191 and the second pulley 192. The cable 193 is attached to the piston 106.

[0126] In this example, guide nut 183 is connected to cable 193. Two pulleys 191 and 192 guide cable 193 and keep piston 106 centered inside cylinder 107.

[0127] When the lead screw 182 moves downward under the operation of the motor 170, it pulls the cable 193 in a manner that causes the piston 106 to move upward. As the lead screw 182 moves upward, the cable 193 allows the piston 106 to move downward. This movement helps to push waste and water away from the cylinder 107 during flushing, and then allows the piston 106 to return to its original position.

[0128] In idle state, piston 106 remains in its original position at the bottom of cylinder 107. When flushing begins, motor 170 rotates lead screw 182 in a first direction. This causes lead nut 183 to move upward, and piston 106 moves accordingly, thereby pushing waste and water out of cylinder 107. A command is sent from controller 100 or directly via actuator 150 to motor 170 to push piston 106 toward drain channel 109 during flushing. These actions can be replaced by the fourth action / state S14 above. In other words, the operation of the water supply device and orifice valve 105 can remain unchanged.

[0129] After rinsing, or at the end of the rinsing sequence, controller 100 or directly via actuator 150 sends a command to reverse motor 170, causing guide nut 183 to move downward and pull piston 106. To return piston 106 to its original position, motor 170 causes guide screw 182 to rotate in the opposite direction, causing guide nut 183 and piston 106 to return downward.

[0130] The cable implementation provides a simple and effective way to control piston movement using mechanical linkage between cables and pulleys, without requiring direct contact or magnets.

[0131] Figure 24B The illustration shows a rodless cylinder with a magnetically coupled linear actuator 180 configured to move a piston 106 up and down.

[0132] The piston 106 is connected to the actuator 180 using a driving magnet 184 and a driven magnet 185. The driving magnet 184 and the driven magnet 185 are magnetically coupled and move together without direct contact. When the actuator 180 moves, the piston follows due to this magnetic connection.

[0133] The linear actuator 180 is configured to convert the rotational motion of the motor 170 into linear motion that moves the piston 106 via a magnetic coupling.

[0134] In idle state, piston 106 remains in its original position at the bottom of cylinder 107. When flushing begins, motor 170 causes actuator 180 to advance in a first direction. This causes piston 106 to move together with the linear actuator via magnetic coupling, pushing waste and water out of cylinder 107. A command is sent from controller 100 or directly through actuator 150 to motor 170 to cause linear actuator 180 to push piston 106 toward drain channel 109 during flushing. These actions can be replaced by the fourth action / state S14 above. In other words, the operation of the water supply device and orifice valve 105 can remain unchanged.

[0135] After rinsing, or at the end of the rinsing sequence, controller 100 or directly via actuator 150 sends a command to reverse motor 170, causing linear actuator 180 to move downward and pull piston 106. To return piston 106 to its original position, motor 170 causes magnetic coupling to move in the opposite direction, returning piston 106 to its original position as it was in standby or ready state.
