[0001] This application claims the benefit and priority of U.S. Provisional Application No. 63 / 733,225, filed December 12, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application generally relates to a rim washer for a toilet bowl. Background Technology

[0003] Given environmental and economic considerations, it is advantageous to reduce the amount of water used during a toilet flush cycle. During each flush cycle, water is used to perform several functions, such as seal restoration, odor blocking, waste removal, basin cleaning, and drain line transport. Reducing the amount of water used with each flush can negatively impact one or more of the functions of water during a flush cycle. Basin cleaning is an area that can be improved by using devices and methods to reduce the amount of water used during a flush cycle while maintaining cleaning performance.

[0004] Providing an efficient flush that removes all contents (e.g., solid waste, liquid waste, etc.) from the toilet bowl during a single flush cycle reduces water usage. Current toilets, designed to use one gallon of water per flush, offer poor overall flushing performance (e.g., leaving contents in the bowl after the first flush), leading to customer dissatisfaction and often requiring additional flushes to completely remove contents from the bowl. Therefore, the need for multiple flushes to achieve proper flushing undermines any potential efficiency gains. Summary of the Invention

[0016] The following description includes an exemplary toilet comprising a water supply system that delivers water to a predetermined portion of the rim of the toilet bowl. The water supply system may also deliver a portion of the water to a sump (e.g., a sump jetter) in the toilet bowl. A plate with openings is used to regulate the water supply to the rim; these openings are sized and spaced to regulate water distribution. Downstream of the plate is a diverter that directs the water flow from the openings to the rear of the toilet bowl. Other water that does not pass through the plate is directed by dual nozzles and moves horizontally from the plate to the sides of the toilet bowl in two directions. These directions may correspond to clockwise and counterclockwise directions relative to the circumference of the rim and / or the toilet bowl.

[0017] refer to Figure 1 The diagram illustrates a toilet 100 including a base 110 (e.g., a pedestal, basin, etc.) and a tank 120. The base 110 is configured to attach to another object (e.g., a drain pipe, floor, or other suitable object). The base 110 includes a basin 111, a sump (e.g., a container) disposed below the basin 111, and a drain passage fluidly connecting the basin 111 to a drain pipe or sewer line. The tank 120 may be supported by the base 110 (e.g., the upper surface of an edge 115). The edge 115 may be integrated with an edge platform 121 that defines the edge 115 and extends behind it. The edge platform 121 may also provide an edge shelf 125 below or within the edge 115, the edge shelf 125 conveying water around the circumference of the basin. The edge shelf 125 may have a predetermined height. The height of the edge shelf 125 may decrease in the direction of water flow through the edge shelf 125. It may include additional, different, or fewer components.

[0018] The tank 120 can be connected to the base 110 by means of a rim 121. According to any of the following examples, the tank 120 is separately formed from the base 110 and the tank 120 is coupled (e.g., attached, secured, fastened, connected, etc.) to the base 110. The toilet 100 may further include a tank lid 122 covering the opening and interior of the tank 120. The toilet 100 may include a seat assembly 130, which includes a seat 131 and a seat cover 132 rotatably coupled to the base 110. The toilet 100 may further include a hinge assembly 135.

[0019] A vertical water passage exists between the base 110 and the tank 120. The connection between the base 110 and the tank 120 may include a seal that maintains a watertight connection between the tank 120 and the vertical water passage. A threaded collar may be integrated with or otherwise attached to a gasket. When the tank 120 is installed in the toilet base 110, the gasket presses against the water passage in the toilet base 110. The weight of the tank 120 presses and compresses the gasket. This, in turn, forms a water passage from the tank 120 to the toilet base 110. Additionally, one or more fasteners (e.g., screws, bolts, etc.) may pass through an opening (e.g., opening 206 in the rim 121) to hold the tank 120 against the base 110.

[0020] The toilet seat or hinge assembly 135 is configured to cover or otherwise enclose the water supply system within the rim 121 for distributing water to the rim and / or sump of the toilet bowl 111. The water supply system may include one or more openings or passages selected to distribute water between the rear portion of the rim 115 of the toilet bowl 111 and the adjacent side of the rim 115. One or more fasteners (e.g., screws, bolts, etc.) may pass through an opening (e.g., opening 205 in the rim 121) to hold the tank 120 against the base 110.

[0021] Figure 2 An exemplary toilet 100 is illustrated that can operate with a water tank 120, but the water tank 120 is not included. Figure 2 The illustration shows only gravity-flush or tank-equipped toilets, but any of the examples and water supply systems below can be applied to flush valve toilets directly connected to a pressurized water supply. In other examples, toilet 100 may include a wall-mounted tank. The toilet seat assembly or hinge assembly 135 is also not shown to illustrate the water supply system 200 below. The water supply system 200 includes a vertical basin passage 210, a horizontal basin passage (e.g., passage 220), Figure 5 ), dispensing cavity 203 and dispensing plate 204. May include additional, different or fewer components.

[0022] A vertical basin passage 210 extends from a gasket or other joint to the water tank 120 and into the water supply system 200. The vertical basin passage 210 may be cylindrical, having a circular or elliptical cross-section. Water enters both the vertical basin passage 210 and the horizontal basin passage 220 under gravity. Water can fill both the horizontal basin passage 220 and the vertical basin passage 210 from the bottom up, and the water displaces air from the passages.

[0023] The horizontal basin passage 220 connects the vertical basin passage 210 to the dispensing chamber 203. When the horizontal basin passage 220 and the vertical basin passage 210 are filled with water from the bottom up and the water pushes air out of the passage and the dispensing chamber 203, the dispensing chamber 203 is filled with water.

[0024] The dispensing plate 204 is adjacent to the dispensing cavity 203. The dispensing plate 204 faces the upstream dispensing cavity and the downstream toilet bowl. The dispensing plate 204 may form a wall or side of the dispensing cavity 203. The dispensing plate 204 may be curved. The dispensing plate 204 may have a shape parallel to the rear portion of the toilet bowl 111. The dispensing plate 204 may have the same radius of curvature as the rear portion of the toilet bowl 111 or within the radius of curvature of the toilet bowl 111 (e.g., between -10% and +10%).

[0025] Figure 3 The diagram shows Figure 2 A cross-sectional view of the toilet (e.g., taken essentially along a vertical plane passing through the water supply system 200). Figure 4 The illustration shows a top view of the water supply system 200.

[0026] The cross-sectional diagram illustrates the spatial relationship between edge 115 and edge shelf 125. A distribution plate 204, positioned perpendicular to edge shelf 125, extends above edge shelf 125 by a predetermined distance. This predetermined distance can be 0.5 to 4 cm above edge shelf 125.

[0027] The dispensing plate 204 may include any of various combinations, shapes, sizes, and relative positions of the openings 202 and teeth 101. While including at least one opening 202, in many embodiments, multiple openings 202 are included. Exemplary numbers of openings 202 are 2, 3, 4, 5, 6, or more. More openings 202 allow more water to reach the rear of the toilet bowl 111, while fewer openings 202 allow less water to reach the rear of the toilet bowl 111. Conversely, more openings 202 allow less water to reach the sides of the toilet bowl 111, and fewer openings 202 allow more water to reach the sides of the toilet bowl 111.

[0028] The teeth 101 extend between adjacent openings. Therefore, when including... n When an opening is included n-1 The opening 202 can be considered as an overflow channel that allows water to overflow onto the distribution plate 204.

[0029] The shape of opening 202 can contribute to the efficiency of water flow. As shown, opening 202 can be crescent-shaped or semi-circular. The arc of the semi-circular shape can form the bottom of opening 202 (e.g., in the direction of gravity). Furthermore, the frictional forces (e.g., drag or pulling forces) applied to the water flow through opening 202 can be minimized due to the semi-circular shape. Other shapes are also possible. Exemplary shapes include squares, rectangles, triangles, and trapezoids. In the trapezoidal example, each wall of opening 202 slopes inward toward the opening, which can be represented by the tooth shape used for a jack-o-lantern.

[0030] The width of opening 202 (e.g., the diameter of a crescent or semi-circular shape) can be substantially equal to the distance between at least one pair of adjacent openings 202. The distance between openings can be measured between adjacent circumferences of adjacent openings 202. In one example, openings 202 can be spaced apart at different intervals. For example, two adjacent openings can be brought closer together to help the vortex in the water rotate clockwise, and two other adjacent openings can be brought closer together to help the vortex in the water rotate counterclockwise.

[0031] Figure 3 The diagram also illustrates a water supply system 200 including an upper supply section and a lower supply section. A vertical basin passage 210 and a horizontal basin passage 220 supply water from a water tank 120 or other water supply section to both the upper and lower water supply sections. Additional, different, or fewer components may be included.

[0032] As described above, the upper supply section uses the distribution chamber 203 and the distribution plate 204 to supply water to the edge 115. Some water is supplied through dual nozzles to the edge shelf 125, to the edge and the side of the toilet bowl. The dual nozzles can be configured as part of the edge shelf 121. Alternatively, the dual nozzles and the distribution plate 204 can be integrally formed in a single configuration. Some water passes through the distribution plate 204 and deflects downwards toward the rear of the toilet bowl.

[0033] The lower supply section supplies water to a sump jetter associated with the sump 141. The lower supply section includes a sump channel 140 configured to deliver water to the sump 141 around the side of the toilet bowl. The sump jetter can propel water into the sump 141 under water pressure from the water supply system or another source. The sump channel 140 includes a right-side channel extending from the right side of the horizontal bowl passage 220 and a left-side channel extending from the left side of the horizontal bowl passage 220. Each sump channel 140 does not extend into the bowl. Each of the sump channels 140 extends around the bowl 111 outside the glass body forming the bowl 111. The sump channels 140 re-converge at the sump 141.

[0034] Figure 5 An exemplary channel 300 in a toilet bowl 111 according to any example of this disclosure is illustrated. The channel 300 is formed in the front side of the toilet bowl 111, guiding water from the edge shelf 125 toward the sump 141 in a predetermined pattern. The channel 300 may be defined by one or more ridges 301 formed in the glass body of the toilet bowl 111. The ridges may be lips, grooves, or another structural feature defining a variation in the height of the toilet bowl 111. Exemplary variations in height include values ​​from 1 to 10 millimeters. In other words, the channel 300 between the ridges 301 can be considered as a recess within the glass surface of the toilet bowl 111, such that water moves generally in the direction of the channel 300 and is focused more directly toward the sump 141.

[0035] Figures 6A to 6B A diverter 234 is illustrated, which is connected to the water supply system 200 and configured to direct water downwards (e.g., in the direction of gravity) to at least one side of the toilet bowl 111. A distribution plate 204 (including...) Figure 2The opening 202 and the tooth 101 shown can be positioned below at least a portion of the steering gear 234. Figure 6A In the example shown, the diverter 234 is substantially vertical and has a top portion 334 that points substantially horizontally toward the rear of the toilet and a bottom portion 335 that points substantially vertically toward the bottom of the toilet bowl 111 or the rear wall of the toilet bowl 111. The interior portion of the diverter 234 receives water flowing through the opening 202 of the distribution plate 204 and directs the water toward the toilet bowl 111.

[0036] Figure 6A The illustration shows a side view of the rear wall of the cleaning water supply unit and the diverter 234. Figure 6B The illustration shows a bottom view of the rear wall of the cleaning water supply unit and the diverter 234. In this example, a vertical spacer 336 may be included between the top of the dispensing plate 204 and the rear end of the diverter 234. The diverter 234 may include a groove or lip that receives the top of the spacer 336. The top of the diverter 234 may include a groove or lip that receives the bottom of the spacer 336. An exemplary horizontal clearance between the dispensing plate 204 and the diverter 234 may be 0.19 inches or 5 millimeters.

[0037] When a component, device, element, or similar object of this disclosure is described as having a certain purpose or performing a certain operation or function, such component, device, or element shall be regarded herein as being "configured" to satisfy that purpose or perform that operation or function.

[0038] Figure 7 The diagram illustrates an exemplary flowchart for the manufacture of a toilet. Additional, different, or fewer actions may be included. Actions may be repeated or performed in any order.

[0039] A toilet bowl base is formed at action S101. This method may include a glass casting method. The casting method may be a solid casting method or a drainage casting method. The toilet bowl base may be cast from other types of materials or combinations of materials (e.g., ceramics, composite materials, epoxy resin, or other types of materials). The toilet bowl base may be integrated with a water passage and a rim plate. The rim plate includes multiple spaced-apart openings to allow water to enter from the water passage. The openings may be semi-circular. The toilet bowl base, including the water passage and the rim plate, may be cast from a single mold. In a drainage casting process, a mold of the basic shape of the toilet bowl base structure, including the water passage and the rim plate, may be filled with liquid clay slurry. The liquid clay slurry solidifies in the mold to cast the walls of the toilet bowl base. The material can then be fired in a kiln.

[0040] At action S103, the diverter is connected to the toilet bowl base. As described herein, the diverter is configured to guide water from spaced-out openings into the toilet bowl. The diverter may be a curved plate that converts the substantially horizontal movement of water flowing from the edge plate into a substantially vertical movement toward the toilet bowl.

[0041] In action S105, the toilet is assembled by placing the water tank into a fluid connection with the water supply passage of the toilet bowl base.
