RETRACTOR ASSEMBLY
CAMPO OF THE I NVENTION The present invention relates to a toilet for the removal of human waste and another. The present invention also relates to a toilet that is resistant to clogging, increases the capacity of automatic discharge, and supplies the volume of discharge water -automatically with greater energy.
ANTEC EDENTS OF THE INVENTION The toilets to remove the waste products are well known. Typically, toilets incorporate three systems that work together to perform the automatic discharge action. These systems are (1) bucket siphon, (2) the automatic discharge mechanism, and (3) the filling mechanism. Working in interest, these three systems allow the function of automatic flushing of the toilet. Siphoning is used to transport the fluid and waste from the highest elevation of the bucket to a lower elevation of the blackwater pipe. The flow channels in a toilet assembly are designed to begin siphoning when the water in the bucket rises above a certain level. The siphon tube itself is a U-shaped tube with a downward face that draws water from the toilet bowl into the sewage pipe. Water is removed from the bucket and into the siphon tube when the - 2 - tread is automatically discharged. The automatic discharge action starts entering the water to the bucket through the action of the automatic discharge mechanism and the filling mechanism. When discharged automatically, the bucket fills quickly with water from the tank placed above, which causes the siphon tube to fill with water, creating a pressure gradient in the tube. The bucket filled with water creates higher pressure at the beginning of the siphon tube, and causes water and waste to be pushed through the pipe and into the sewer pipe. Typically, the tank, placed on top of the bucket, contains water that is used to initiate the siphoning of the bucket into the sewer pipe, as well as to fill the bucket with fresh water. When a user wishes to flush the toilet, he pushes down the automatic discharge lever on the outside of the tank, which connects on the inside of the tank to a moving chain or lever. When the automatic discharge lever is lowered, it moves a chain or lever in the internal part of the tank, which is activated to raise and open the automatic discharge valve, causing the water to flow from the tank and into the tank, initiating in this way the automatic flushing of the toilet. In various toilet designs, water flows either directly into the tub or disperses to the rim of the toilet tub. The edge typically has several small holes to allow flow to the bucket. The water is released - 3 - to the bucket in turn quickly, with flow from the tank to the bucket typically lasting approximately two to four seconds. Water flows from the rim, down a channel inside the sides of the bucket, to the large hole in the bottom of the toilet, commonly known as a siphon jet. The siphon jet releases most of the water to the siphon tube, initiating the siphoning action. The siphoning action draws all the water and waste out of the bucket, and into the siphon tube. The waste and water continues through the other end of the U-shaped siphon tube through an area known as the trap path, and is released into the sewage pipe connected to the toilet base. Once the tank is emptied or its contents (fresh water) during the automatic discharge, the automatic discharge valve closes, and a floating mechanism, which has now fallen into the tank for some residual amount, initiates the opening of the filling valve. The fill valve provides fresh water to both the tank and the tank through separate flows. Eventually, the tank is filled with water at a level high enough to cause the float to rise, thereby disconnecting the filling valve. At this point, the automatic download cycle is completed. However, government agencies have continually claimed that municipal water users reduce the amount of water they use. The main objective in the current 4 years has been to reduce the water demand required by the automatic toilet flushing operations. To illustrate this point, the amount of water used in a toilet for each automatic discharge has been gradually reduced by government agencies from 26 liters / automatic discharge (before 1 950), to 20 liters / automatic discharge (at the end of 1960), at 13 liters / automatic discharge (in 1 980). The National Energy Action Plan Act of 1995 now mandates that toilets sold in the United States be able to use water in an amount of only 1.6 grams / automatic discharge (6 liters / automatic discharge). In the past, toilet designs have tried by various methods to meet this reduced water requirement, but achieving superior automatic discharge performance has been difficult. Therefore, it has been found desirable to provide a toilet that will assist the automatic discharge operation in complying with the ordered water requirements while at the same time providing a superior and improved automatic discharge operation. In populated matter to produce a more reliable, more efficient, and more powerful toilet of 1.6 gallons (6 liters) of gravity, one method to more effectively remove waste from the toilet tub is to increase the hydraulic power available during the operation of automatic download. However, the available hydraulic power is not improved by the typical rim washing employed in the existing toilets as the flow path flows in two opposite directions across the rim of the toilet thereby reducing the energy available. Therefore, it has been found desirable to provide a toilet that increases the hydraulic power of the automatic edge discharge. Current agency requirements also mandate that the automatic discharge lever for the automatic discharge valve assembly has a minimum "hold" time of 1 sec. Without exceeding the aforementioned water usage or discharge by automatic discharge of 1. 6 gallons (6 liters) of water. It has been found that the hydraulic performance characteristics of the automatic discharge valve can be significantly improved if the water can be evacuated from the tank in a discharge time of less than 1 second, preferably 0.5-0.6 seconds. Therefore, it has also been found desirable to provide a toilet that releases the effect of the automatic release lever or release member such that the opening of the valve can be closed before the expiration of the minimum time of orderly "hold" of the valve. automatic discharge lever (1 sec undo) without exceeding the total amount per automatic discharge command of 1.6 gallons (6 liters). In the development of the invention of this application, several toilets were examined and tested. Measurements were made to examine automatic discharge capabilities. In order to determine the properties of clogging and non-clogging of these toilets, various objects were automatically discharged through the - 6 - the toilets, including the pin balls, the thick napkins, floating Polypropylene balls, foam sponges, and floating rubber tubes. These objects were used to simulate various sizes and forms of waste. All tested designs share some of these problems, but in varying degrees. First, several of the models had obstruction problems. In most of these toilets, this problem could be attributed to a purge way of insufficient dimensions. Second, when there is a significant level of waste in the bucket, several of the designs were not able to clean the bucket in a single automatic discharge. Third, several of the toilets used a symmetric sweeping flow path to supply the volume of flow to the rim, which perhaps reduced the efficiency of the toilet. Fourth, the automatic dump valve in several of the toilets was not able to provide both a rapid and high volume of water supply to the tank. Finally, several of the toilets produced a desirable amount of noise during the automatic discharge. These tests confirmed the desirability of providing a toilet assembly that achieves a maximum purge route but did not reduce the siphon effect. It is therefore desirable to provide a toilet that allows for quieter automatic discharge and reduce the likelihood of clogging, increase the discharge capacity to utomatic, and create an automatic vortex discharge action by having a current ripple flow. asymmetric supplier. This - 7-tread includes an automatic discharge valve that minimizes hydraulic power losses and allows for the smooth transition of water flow from the automatic discharge valve to the edge channel supplies and the spout.
OBJECTS AND BRIEF DESCRIPTION OF THE INVENTION Therefore, an advantage of the present invention is to provide a toilet that avoids the aforementioned disadvantages of the prior art. An additional advantage of the present invention is to provide a toilet that is resistant to clogging. Another advantage of the present invention is to provide a toilet with an automatic discharge mechanism that is capable of cleaning the tub in a single automatic discharge. A further advantage of the present invention is to create a toilet that is self-cleaning. Still a further advantage of the present invention is to provide a toilet with a relatively silent automatic discharge mechanism. Still further a further advantage of the present invention is to provide a toilet with a large purge path diameter. Still another advantage of the present invention is to provide a toilet with a high discharge velocity in the wastewater pipe.
Yet still another advantage of the present invention is to provide a toilet having a sweep flow path to supply the automatic discharge volume to the spout and edge sections with higher energy. Still a further advantage of the present invention is to provide a retret on a direct jet path ^!
provide a toilet that reduces hydraulic losses. Yet another advantage of the present invention is to provide a toilet having an asymmetrical rim path flow resulting in a vigorous whirling action. In accordance with the present invention, a new and improved toilet is provided which includes a toilet bowl assembly having a toilet tub and a vent passage extending from the bottom of the toilet tub to a water tubing. black The toilet bowl has an edge portion along an upper perimeter portion accommodating an asymmetric flow path for the automatic discharge water. A water tank placed over the toilet bowl assembly contains water that is used to initiate the siphoning of the toilet bowl into the black water line and fills the toilet bowl with fresh automatic discharging water after each operation of automatic download.
- 9 - This toilet incorporates water supply to the bucket both from direct spout flow as well as an asymmetric rim flow. Water flows from the tank through the rim in one direction and is dispersed through a middle muesca path around the rim (at the front of the trough) and another notch at the end of the rim path (at the end of the rim path). back of the bucket). The water also flows through several other smaller holes distributed very along the perimeter of the edge. The water discharged from the two large edge notches is in two powerful currents, thus creating a strong eddy that initiates the automatic discharge action. This water discharge configuration creates a high energy jet. The dispersion of the smaller holes around the perimeter of the bowl serves to wet and clean the bowl. This toilet includes a purge way without reductions in cross-sectional area. This feature prevents clogging, because any charge that passes through the bleeder continues through the blackwater pipe. This bleeder way is also larger than the existing bleeder ways, which improves the anti-clogging capability of the toilet. This increased purge path size also increases the rate of waste discharge at the end of the system in your sewage system. Various other advantages and features of the present invention will become readily apparent from the incoming detailed description and the new features will be pointed out - particularly in the appended claims.

DETAILED DESCRIPTION OF CI ERTAS MODALI DADES
PREFERI DAS Referring now to Figures 1-3, a toilet tank according to the teachings of the present invention is illustrated. As will be explained in more detail below, this toilet has a greater energy output from the automatic discharge water to thereby provide greater available energy to remove the waste from the toilet tub. In addition, this toilet allows a toilet to comply with the requirements of the governmental agency which order a maximum use of water of 1.6 grams per 6 liters per automatic discharge. In addition, this toilet improves flow characteristics of flow water and flow capacity to provide not only more efficient automatic discharge but also improved cleaning performance and anti-clogging siphoning to assist in the removal of debris. In addition, this toilet provides a faster and quieter automatic discharge operation. As shown in Figures 1 -3, the toilet 1 0 includes a water tank 12 that includes an automatic discharge valve assembly 14. The water tank 1 2, which is placed on the back of the tank toilet 20, contains water that is used to initiate the siphoning of the tub to the tubing of aquas neqras, user wants to clean by flushing the toilet, the user pushes down the automatic discharge lever 1 8 on the outside of the water tank, which is connected to the automatic discharge valve assembly 14 by a moving chain or lever. When the automatic discharge lever 1 9 is lowered, the chain or lever 1 9 is operated to leave the automatic discharge valve to be described hereinafter open, causing the flow to flow from the tank 1 2 and into the tank. of toilet 20, thus initiating the automatic discharge of the toilet.
- 1 5 - In this toilet, the automatic discharge system passes from the water tank 1 2 to the toilet tank 20 through a transition path 22, which will be described in greater detail below, can be configured as a pipe made of plastic. This transition path 22 directs the automatic discharge water either to an edge channel 24 provided in the upper part of the toilet bowl 20 or to a direct spout channel 29. As will be described in more detail below, the Automatic discharge flows through the edge channel 24 of the toilet in a path that is asymmetrical and unidirectional (see arrows A of Figure 3). This edge channel 24 includes a plurality of edge openings such as 2a, b, c and d distributed very far along the perimeter of the edge channel 24 such that a portion of the automatic discharge water in the edge channel 24 flows through them and along the sides of the toilet tub in order to pre-moisten the entire perimeter of the toilet tub and provide the side wall cleaning operation. In order to increase the efficiency of automatic discharge and operation of the toilet, a pair of discharge notches for water 28a and 28b are provided in the edge channel 24 in such a way that the automatic discharge water passing in the asymmetric passage to Through the edge channel 24 can be distributed either from the edge channel 24 to the toilet bowl through one of the plurality of edge openings, such as 26a, b, c and d, or through a pair of notches discharge for water 28a and 28b. These notches of - 1 6 - water discharge 28a and 28b discharge the automatic discharge water directly into the toilet bowl 20 in two streams of water (see arrows B &C in Fig. 3) which create a strong action of swirl to provide greater siphon energy for removal as will be appreciated in more detail below. As shown in Fig. 3, one of the pair of water discharge notches 28a is provided approximately half-life around the edge channel 24 and the second of the water discharge notches 28b is provided in a subsequent section. of the toilet tub 20. During the automatic discharge operation as described above, water flows from the edge openings 26a, b, c and d under the sides of the bowl or directly towards the toilet bowl 20 through the water discharge notches 28a and 28b towards the large discharge orifice 30 provided in FIG. the lower part of the toilet bowl 20 known as the siphon dispenser. The automatic discharge water is also supplied directly to the siphon jet via the direct spout channel 29. The direct spout frees up most of the water in the trap path 40 by initiating a siphoning action. The siphoning action draws all the water and waste out of the toilet bowl and into the bleeder way 40 and thus is released into the sewer line connected to the base 31 of the toilet 10. Once the tank is emptied From its default volume during automatic discharge, the opening of a - 1 7 - fill valve (not shown) starts. The fill valve provides fresh water for both the water tank 1 2 and the toilet tank 20 through separate flows. Eventually, the water tank 1 2 fills a water lever to cause a buoyancy of the automatic discharge valve assembly 14 to rise, thereby disconnecting the fill valve. The automatic download cycle is now complete. A more detailed description of the components of the toilet 10 of the present invention follows. As shown in Figures 4 to 6, the automatic discharge valve assembly 14 of the present invention includes a valve body 32, an automatically discharging cover member 34 of a predetermined length, and a "release mechanism". disengagement "or" lost movement "36. The valve assembly 14 allows the water tank to which it is installed to maintain a predetermined volume of water and also serve as a conduit for supplying water to the toilet trap passageway by means of the steps inside the toilet. The valve body 32 includes a base sleeve portion 38 that is secured to the water or odor tank by a threaded member 39 provided along the outer peripheral surface 40 of a base support portion 41 thereof. The valve body 32 also includes a first inductive tube member 46 that extends vertically from the base sleeve portion 38. In order to properly seal the body-1 8 -of valve 32 to the water tank, a member of the valve body 32 The seal or washer 42 is fitted over the threaded member 39 so as to be spliced against an annular flange surface 43 of the base sleeve part 38. A seal liner 44 is threaded onto the threaded member 39 in order to securely place the sealing member 42 between the annular flange member 43 and the sealing coating 24. The automatic discharge valve cover or closure component 34 is mounted coaxially and slidably with respect to the valve body 32 in such a way that A valve opening 50 is created between the valve body 32 and the automatic discharge valve cover 34 when the automatic discharge valve cover 34 is removed from the valve body 32. The cover The automatic discharge valve 34 is slidably movable between a first rest position, wherein the automatic discharge valve cover 34 is positioned on an annular valve seat 52 of the base sleeve portion 38 of the valve body 32 of the valve body. such that the water can not pass through valve opening 50 (see Figs. 4 and 8), and a second position, wherein the automatic discharge valve cover 34 is removed from the annular valve seat 52 of the base sleeve portion 38 of the valve body 32 such that the water can pass through. of the valve opening 50 (see Figs 5 and 9). The open position of the valve opening 50 allows the flow of automatic discharge water to enter the valve opening and proceed into the passages within the toilet to which the water tank is attached.
- 19 - As set forth below, the automatic discharge valve assembly 14 of the present invention achieves a higher energy output of the automatic discharge water, which in turn generates more energy available to remove debris from the bucket. of toilet In order to obtain this advantageous result, the base sleeve part 38 of the ventilation tube includes an inlet with radius 58 having a diameter which is approximately 1 1 .42 centimeters with a radius of 8.63 centimeters (see Fig. 7) incorporated on the driving edge 58a of the entrance. As a result, the entry with radius 58 of the base sleeve part 1 8 creates a discharge coefficient of the valve opening of 0.95. The discharge coefficient is the ratio between the current flow area of the opening area and the static opening area. In practice, the higher the discharge coefficient of the opening, the greater the hydraulic energy of the water passing through the opening. Without providing an inlet with radius in the valve opening with a connection angle as in the present invention, the discharge coefficient of the valve opening of the prior art is about 0.6. According to the foregoing, the output power of the automatic discharge water passing through the valve opening of the automatic discharge valve assembly 14 of the present invention is greater than the output power of the automatic discharge water. which passes through the existing valve assemblies of the prior art as discussed above. As a result of the 20-radius inlet 58 of the base sleeve portion 38 of the valve body 32 as described above, the flow characteristics of the automatic discharge water and the flow capacity of the automatic discharge valve assembly of the the present invention are improved. Therefore, greater energy is generated in the automatic discharge water that passes through this automatic discharge valve assembly to remove waste in the toilet tank. In order to accommodate the unrestricted counterflow in the water tank, the automatic discharge valve cover 34 includes a channelized inlet 59 in the automatic discharge water inlet orifice 60. This channelized inlet has a predetermined guide angle ß to the horizontal axis of the automatic discharge valve cover (see Figure 7). As shown in the Figures, especially Fig. 4, the automatic discharge valve cover 34 may include an upper part 34 ', a lower part 34", and a part 34"' located between them which may be a part inclined or stepped. The diameter of the upper part 34 'may be smaller than the diameter of the lower part 34". Additionally, the annular sealing member 64 provided along the lower surface of the automatic discharge valve cover 34 has a diameter that can be larger than the bottom 34". The inclined portion 34"'and the diameter of the annular sealing member 64 can be designed and / or selected so as to allow a force to be exerted on the automatic discharge valve cover-21 during a filling operation which is sufficient to pull the automatic discharge valve cover 34 down and cause an adequate seal to be formed, such force may be the minimum force necessary to pull the automatic discharge valve cover 34 downward and provide the proper seal. , the diameter of the lower part 34"is selected in order to provide a desired buoyancy of the automatic discharge valve cover 34. Such buoyancy may affect the period of time in which the automatic discharge valve cover 34 remains open. In this manner, the automatic discharge valve cover 34 can provide a desired buoyancy and allow a minimum drive force to be applied thereto while providing an adequate sealing condition when the automatic discharge valve cover is moved to Your first resting position. further, the flow characteristics of the automatic discharge water and the flow capacity of the automatic discharge valve assembly 14 of the present invention are also improved by reducing the driving force required to properly close and seal the valve opening 50 when the cover of automatic discharge valve 34 is moved from its second upper position to its first resting position. According to the same, in the automatic discharge valve assembly 14 of the present invention, an annular valve seat 52 is provided downstream of the inlet with radius -22-58 in the water discharge opening of. automatic download 61. As best shown in Figs. 6 and 7, the annular sealing member 64 is provided along the outer circumferential surface 63 of the automatic discharge valve cover 34 which rests on the annular toothed valve seat 52 when the valve cover of FIG. Automatic dump 34 is in its first resting position. In order to adequately gage and align the automatic discharge valve cover 34 with respect to the valve body 32 when the automatic discharge valve cover 34 moves between its first and second rest position, the discharge valve cover Automatic 34 includes a second internal cylindrical tube member 68 secured to the inner peripheral surface of an internally downwardly dependent vertical wall member 70 of the automatic discharge valve cover 34 by means of a plurality of network members radially disposed. (not shown) bridging the second tube member 68 between the inner wall member 70 and the second cylindrical tube member 68. The second cylindrical tube member 68 is fixed on the first cylindrical tube member 46 of the valve body 32 in such a way that the automatic discharge valve cover 34 is properly guided and aligned exactly with the valve body 32 when the automatic discharge valve cover 34 moves between its first rest position and the second upper position.
- 23 - This guide assembly consisting of the first and second inductive tube members, 46 and 68, respectively, also helps to properly seal the valve opening 50 when the automatic discharge valve cover 34 returns to its first position. Rest. The guide assembly ensures that the annular sealing member 64 fitted on the automatic discharge valve cover 34 is suitably positioned on the annular valve seat 52 of the valve body 32 in the first resting position of the discharge valve cover. automatic 34. In order to reduce hydraulic losses and further improve the flow characteristics of the automatic discharge valve assembly 34, the valve body 32 includes a structure for minimizing the flow resistance. This flow resistance minimizing member includes a plurality of conical network members 72a, 72b, 72c radiantly disposed between the first cylindrical tube member 46 and an inner peripheral portion 73 of the base sleeve portion 38 of the valve body 32. As shown best in FIG. 7, each tapered network member 72a, 72b, 72c is formed from a lower height section 75a at one end toward the first indic tube member 46 which increases in height through a conical section 75b until the extended height section 75c is reached at one end towards the outer peripheral surface 53 of the base sleeve part 38. With this design, the turbulence of the automatic discharge water passing through the Valve discharge opening 61 is optimized.
- 24 - Hydraulic losses can also occur as a result if the water does not flow in a laminar manner. The laminar flow can be broken from the automatic discharge water during the automatic discharge operation, the adequate buoyancy of the automatic discharge valve cover 34 must be provided in such a way that the automatic discharge water will be properly drained. In order to provide floatability of the automatic discharge valve cover 34 when the automatic discharge valve cover 34 moves from its first rest position to its second rest position in order to achieve automatic discharge water drainage. According to the invention, a buoyancy cavity 76 is formed between the inner and outer wall members that depend downwards 70 and 78, respectively, of the automatic discharge valve cover 34. As with the typical automatic discharge valve assemblies, the the automatic discharge valve cover 34 initially moves from its first rest position, where the valve opening 50 is closed, to a second position, where the valve opening 50 is opened by means of an automatic discharge lever 1 8. This automatic discharge lever 1 8 is displaceable by a user between a first rest position and a second position to move operatively the automatic discharge valve cover 34 between its first rest position and second upper position.
- 25 - The current agency requirements dictate that the minimum "hold" time for the automatic download flag is one second. However, the longer the valve opening remains open before the water is evacuated from! Therefore, more energy will dissipate during the automatic discharge cycle. The automatic discharge valve assembly of the present invention can achieve closing of the valve opening 50 in less than 1 second, preferably in 0.5-0.6 seconds, to increase the available hydraulic energy of the automatic discharge water and ensure thereby providing a relatively rapid supply of a predetermined amount of automatic discharge water without exceeding agency requirements. According to the same, the automatic discharge valve assembly 14 of the present invention includes a "release release" or "lost motion" mechanism 36, which, as described below, releases the effect of the automatic discharge lever 1 8 in the automatic discharge valve cover 34 when the automatic discharge valve cover 34 reaches its second position in order to return the valve cover of automatic discharge to its first rest position before the automatic discharge lever 8 returns to its first resting position. As shown in the drawings, the release release mechanism 36 includes a cam rod 80, a drive rod 82 operatively connected to the driver discharge lever at the end 82a and mounted in a removable manner. with respect to the cam rod 80 such that the driving rod 82 and the cam rod 80 are movable in response to the movement of the automatic discharge lever. A disengagement limiting stopper 90 is also incorporated into the release release mechanism 36 which is capable of engaging the self-discharging valve cover 34 when the drive rod 82 and the cam rod 80 move between a first rest position and a second predetermined position and is capable of disengaging the automatic discharge valve cover 14 when the driving rod 82 moves beyond its second predetermined position. As best shown in Figures 6, 7 and 10, the driving rod 82 includes a plurality of extension members, such as 77a and 77b, which includes a narrow width section 79a gradually increasing in width to a high width section. 79b. The high-width members 79b extend outwardly to a degree which can thus be received within a receiving opening 1 00a formed by the inner peripheral surface of an annularly inclined deflector 100, to be explained in more detail below. Each of the raised width members 79b includes a gear hole 79c at a lower end thereof. The engaging and disengaging members of the stop assembly of the release imitator 90 include reel-like retention members 92a, 92b which are supported in the holes 27-ingrain 79c of the members 79b high width members. extensions 77a and 77b. As shown in Figure 8, the blade-like retention members 92a, 92b extend outward to engage the automatic discharge valve cover 34 when the cam rod 80 and the pull rod 82 are moved together between its first position and a second predetermined position in order to move the automatic discharge valve cover 34 between its rest, first and second positions. Further movement of the cam rod 80 is restricted by passing this second predetermined position as will be described in greater detail below. With the movement of the constrained cam rod 80, Figure 9 illustrates that the reel-like retention members 92a, 92b retract when the trailing rod 82 moves to its second predetermined position in order to disengage the reel-like retention members 92a, 92b of the automatic discharge valve cover 34 which in turn allows the automatic discharge valve cover 34 to return to its first resting position. More specifically, as shown in FIGS. 6 and 8, in the first rest position of the cam rod 80 and the driving rod 82, a first detent member 93 of each retention member similar to blade 92a and 92b is spliced against a slanted driving surface 94a of a central depressing cam section 94 of the cam rod 80. The driving edge 95a of a second securing member 95 of the retention members -28 -similar to blade 92a 92b is spliced against a section of red diameter 80a of the central depression cam section 94 of the driving rod 82. Each of the reel-like retention members 92a, 92b further include a gear section 97 that is rotated to extend downward and to be repositioned in such a manner when the cam rod 80 and the driving rod 82 return to their first rest positions. As the automatic discharge lever 18 initially moves the cam rod 80 and the driving rod 82 from its initial rest positions, the first and second securing members 93 and 95 of the reel-like retention members are contained within of the central depression cam section 94 of the cam rod 80. In the additional combined movement of the cam rod 80 and the driving rod 82 due to the additional depression of the automatic discharge lever, the engagement section 97 of each retention member 92a and 92b is meshed with an annularly sloping baffle member 100 (see Fig. 7) extending from an inner peripheral surface 1 02 of the automatic discharge valve cover 34 to elevate the automatic discharge valve cover 34 from its first rear position, where the valve opening 50 is closed, to a second upper position, where the valve opening 50 it opens. When the cam rod 80 and the driving rod 82 have moved towards the second predetermined height position in the depression of the automatic discharge lever, a base flange 29 of annular 80b provided on a base section 80c of the rod Cam 80 is spliced against an outwardly extending flange 46a provided at the upper end 46b of the first cylindrical pipe member 46 of the valve body 32 (see Fig. 9). This restricts the further movement of the cam rod 80 with the driving rod 82 as the automatic discharge lever 1 8 tilts further. When the driving rod 82 moves past this second predetermined position by additional depression of the automatic discharge lever 1 8, the driving rod is subjected to the additional deflection force which is applied by an elastic member 104 which is fixed on a upper part of the cam rod 80 and is loaded between a central core member 1 06 of the driving rod 82 (see Figs 7 and 10) and an elastic hook 1 08 provided at an upper end of the rod cam 80 (see Figure 10). Since the cam rod 80 is prevented from further movement, when the driving rod 82 moves past the second position of predetermined height and the deflected force begins to be applied thereto, the securing members, first and second, 93 and 95 slide from the central depression cam section 94 of the cam rod 80. This, in turn, causes the blade-like retention members 92a and 92b to rotate (see Fig. 9) in such a way that the engagement section 97 of the retention members 92a and 92b are retracted towards the drive rod 82 and disengaged from the annularly inclined deflector member 1 00 of -30-the automatic discharge valve cover 34. As a result , since the automatic discharge lever 18 is connected to the driving rod, the automatic discharge valve cover 34 is no longer under the effect of the automatic discharge lever 18. Since the automatic discharge valve cover a is not restricted, the automatic discharge valve cover 34 is able to return to its first resting position. The driving rod 82 continues its vertical movement passing to the second predetermined position until the central core member 1 06 is butted against the elastic hook 1 08. At this point, the additional movement of the driving rod 82 is restricted . This automatic discharge operation causes the closing of the valve opening in approximately 0.5-0.6 seconds provided a relatively rapid automatic discharge operation which causes the reduced energy dissipation of the automatic discharge water during the automatic discharge operation. Even though the automatic discharge valve cover 34 returns to its first rest position to close the valve opening 50, the driving rod 82 continues to move upwards until the automatic discharge lever 1 8 has fulfilled its "hold" time command of one second. In addition, the second indian pipe member 68 of the automatic dump valve cover 34 includes an annular extended flange 1 1 1 at the upper end thereof (see Fig. 7). When the cam rod 80 and the driving rod 82 return to their first resting position in a subsequent automatic unloading operation and the effect of the automatic unloading lever is released, the cam surfaces 109 of the toothed members retracted 72a and 72b are spliced against the annular extended flange 1 1 1 of the second cylindrical tube member 68. As the cam surfaces slide over them, the blade-like retention members 92a, 92b are cam-lifted a disengageable position extended in such a way that the first securing member 93 of each reel-like retention member 92a and 92b is spliced against the inclined driving surface of the central depression cam section 94 of the cam rod 80 and the members Retainer members 92a and 92b are rotated in a position by which the engaging member 97 is able to engage the annularly inclined deflector member 1 00 of the automatic discharge valve cover 34 in a subsequent automatic discharge operation. By including the mechanism of. "releasing release" or "lost movement" 36 in combination with the other features set forth above, the flow characteristics of the automatic discharge water and the fullying capacity of the automatic discharge valve assembly are improved while at the same time compliance With the ordered agency requirements is achieved. Figure 1 1 illustrates a sweep entry 1 1 0 that provides a transition between the water tank 12 and the transition path 22 in order to maximize the water output energy of -32-automatic discharge that passes into the path of transition 22 which in turn creates more energy available to remove waste from the toilet tub. As shown in Figure 11, the sweep input 1 0 has a port with radius 1 12 at one end thereof having an inclined leading edge 1 12a, similar to the entry with radius 58 of the of base sleeve 38 of the automatic discharge valve assembly of Figures 4-9. The port with radius 1 12 has a diameter of preferably about 1 0.15 centimeters which is conifed to a narrow diameter of 7.61 centimeters between the side walls 1 14a and b. The driving edge 1 1 2a is inclined towards the horizontal axis of the water tank 12 at an angle of connection a. As a result of this valve inlet design, the discharge coefficient of the automatic discharge valve is increased to approximately 0.95. By increasing the discharge coefficient, the hydraulic energy of the water passing through the automatic discharge valve is increased. As a result, the hydraulic losses of the automatic discharge water that passes from the tank to the spout and flange supply channels are reduced in such a way that more energy is created in the automatic discharge water to remove the waste in the toilet tank. . Fig. 1 2 is another assembly for an automatic discharge valve with improved hydrodynamics. This type of automatic dump valve also includes a valve inlet 1 1 5 that has a port with radius 1 16 but does not require elevation of the platform for the water tank as in the valve inlet 1 1 0 of Figure 1 1. Due to the lack of elevation of the platform for the water tank, in order to provide adequate sealing, the valve inlet The pillars of Figures 11 and 12 are set forth herein for illustrative purposes. These designs provide a delivery speed of approximately 7.5 liters / sec. in the transition path 22. As it could be known by an expert in the field, an automatic discharge valve cover, such as in the automatic discharge valve assembly of Figures 4-9, may be used in conjunction with any of these valve inlets 1 1 0 and 1 1 5. Alternatively, other valve assemblies may be used. of known automatic discharge can be adapted to be used together with these concepts of pillars. Figure 1 3 illustrates the transition path or round bend 22 which is conducted from the automatic discharge valve assembly of the water tank 12 to the edge channel 24 and direct water channel 29. As shown in the FIGURE 1 3, the radius R of the round bend 22 is at least 7.61 centimeters, that is, the radius R must be at least equal to the narrow diameter of the input with radius. At the inlet end 1 16 of the transition path 22, the automatic discharge valve assembly, such as 14 herein will be fitted with a fork with radius (not shown). The transition path 22 is preferably made from Chinese porcelain and thus provides smooth flow transition from the automatic discharge water of the automatic discharge valve 1 2 to the edge channel 24 and the channel of its water jet. direct 29. Therefore, together with the automatic discharge valve assemblies with radius input as set forth above, a "sweep" flow path is provided to supply the volume of automatic discharge water with increased energy to the channel of edge 24 and the direct spout channel 29. As mentioned above, the automatic discharge water supplied from the transition path 22. either passes to the edge channel 24 or the direct water spout channel 29 provided in the section posterior of the toilet tub. As best shown in Figures 1 and 3, the water spout channel 29 is relatively large preferably (4.12 centimeters in diameter) such that a concentrated stream of automatic discharge water is directed towards the siphon spout 30 to the base of the toilet bowl (see arrow C in Fig. 3). Since this toilet has a single side spout feed, the hydraulic losses of the automatic discharge water are compared to a toilet design having spout ports on both sides of the toilet bowl leading to the performance of the toilet. improved automatic download. FIGS. 1 and 3 illustrate that the automatic discharge fluid flows through the spiral edge channel 24 in an unrestricted supply path that is asymmetric and unidirectional. In order to create the balanced flow of toilet water between the channel of the skirt 24 and the direct spout channel 29, approximately 1.7 liters of water passes through the edge channel 24 during each automatic unloading operation. In the preferred embodiment, the edge cross section is approximately 3.17 centimeters x 3.80 centimeters. As described above, the edge channel 24 has two water discharge notches 28a and b, such as the discharge notch shown in Fig. 14. As shown in Figs. 1 and 3, one of the discharge notches. 28a is provided in a front section 1 17 of the edge channel 24 and has a preferred dimension of approximately 7.61 centimeters by 1.58 centimeters and the second discharge groove 28b is provided in a rear end section 1 1 8 of the edge channel 24 and has a preferred dimension of approximately 1 0.15 centimeters x 2.53 centimeters. The automatic discharge water is discharged through the first and second discharge notches, 28a and 28b into two powerful streams to generate a strong swirling action in the pool. This swirling action, in combination with the water jet action supplied from the spout channel 29 and the siphon vacuum, leads to a faster and more complete removal of waste from the toilet bowl as well as provides an operation of effective bucket cleaning. As shown in Figs. 3 and 15, the edge channel 24 also includes a plurality of edge openings, such as 26a, b, c, and d. In the preferred embodiment, twenty-five openings of the skirt are distributed completely along the total perimeter of the edge channel 24. Each of the edge openings 26a, b, c and d has a diameter of approximately .553 centimeters with a slope of approximately 3.80 centimeters. The automatic discharge vessel that passes through the edge openings 26a, b, c and d pre-moistens the total perimeter of the toilet bowl 12. Even though the energy is dissipated in the automatic discharge facility that passes through the edge openings 26a, b, c and d, still water contributes additional energy to the creation of a strong vortex in the toilet bowl sink to quickly and efficiently remove the waste. In this cleaning process as described above, the sides of the buckets are pre-wetted due to the water passing through the edge openings 26a, b, c and d. In addition, the strong swirling action created by the water passing through the siphon jet 29 and the discharging mues 28a and b effectively washes the walls of the toilet bowl. Figure 1 6 illustrates in greater detail the automatic discharge water flow through the edge channel 24, and more particularly, the lateral entry of the flow of water from the transition path 22 'to the edge channel 24, as shown by the arrows D. Fig. 1 6 further illustrates that a strong vortex action can be achieved if the automatic discharge water is discharged from the edge channel 24 to the toilet bowl 20 by concentrated water streams. , such as the water streams - 37 - represented by the arrows E and F. These two streams E and F compensate each other and create a strong but not turbulent swirling action in the toilet bowl. The two streams E and F are formed by the automatic discharge water which is discharged through the pair of water discharge notches 28a and 28b provided in the edge channel 24. Fig. 1 6 illustrates that one of the notches of discharge 28a is provided in the middle part of the edge channel path in the front of the toilet bowl and the other discharge groove 28b is formed in the spiral terminal of the edge channel 24. By providing the second and last notch At the end of the edge channel 34, the water flows reliably in a sufficient amount through the plurality of the edge openings, such as 26a, b, c and d so that the total perimeter of the toilet bowl clarifies. It has been found that by providing two concentrated streams of water, such as streams of water E and F, the efficiency of automatic discharge is improved and the losses of energy are reduced. In addition, in the design of this toilet, applicants have found that it is advantageous to obtain the unrestricted continuation of the water stream after the automatic discharge water is discharged from the edge channel 24. This objective can be achieved by forming a wall. of uniform inclined end, such as 140 (see Figure 17) at the rear end of the final discharge notch 28b. If the wall 140 were vertical instead of horizontal, inclined water flow, it is significantly retarded and the energy - 38 - is lost. FIGS. 18 and 11 illustrate another preferred embodiment of the configuration of an edge channel 1 for the toilet assembly of the present invention. In this embodiment, the automatic discharge water enters the edge channel 150 of the transition path 22"on one side of the same.The automatic discharge water flows around the edge channel 1 50 towards the direction of arrows G in Fig. 1 8 in a path that is asymmetric and unidirectional Along this path, a first group of edge openings 152a, b and c, preferably three in number, are provided in the middle part of the edge channel path in the front of the toilet and a second group of edge openings 154a, b and c are provided at the end of the spiral edge path. A water discharge slot 56 is also formed in the edge channel 1 50 after the last second group of the edge openings 1 54c. In this embodiment (Fig. 1 8), the edge openings 152a, b and c, and 154a, b and c are relatively large and are located close to each other. The narrow walls (see 1 58a, 1 58b) between the edge holes provide rigidity in the vertical direction and reduce the distortion of the water flow. In total, the combined area of the edge openings 1 52a, b, and c and 1 54a, b and c should be approximately equal to the respective water discharge notches 28a and b in the embodiment of Figure 3. By providing two groups of openings As shown in Figure 1 8, a strong swirling action of the automatic discharge water is obtained with a water level that is distributed along the perimeter. In the edge channel 1 50 of FIG. 1 8, the unrestricted continuation of the water stream is achieved after the automatic discharge water has completed the full edge path of the edge channel 1 50 forming the water discharge slot 156 in a vertical wall 1 60 of the edge channel 1 50. As a result, the automatic discharge water discharged through the water discharge slot 1 56 continues to flow in a horizontal direction and by consequence it does not lose kinetic energy as could result if the automatic discharge water impinged on a vertical wall after full flow through the edge channel 50. Figure 20 illustrates the configuration of the toilet bowl 20. Figure 20 illustrates that the toilet tub 20 has sufficient depth and sufficient width to have a large enough water stain so as not to collect too much water. Upon completion of the automatic discharge process, the discharge water to utomatic and the waste material pass through the siphon supply 30 in the purge way 40 that leads to the sewage pipe. As shown in Fig. 1, the bleeder way 40 has a first weir area 1 62 that is connected to a first biased downstream bleeder track section 164. The length of the first bleeder track section 164 is minimized in such a manner. that the water in the sink is maintained, the first -40 -fouring area 1 62 and the first venting-way section 64 is approximately 0.475 l (see Fig. 21). The first bleeder track section 64 leads to a second downstream bleeder track section 66 which, as shown in FIG. 21, has a slope that faces the trough at an angle of approximately 30 °. . A second landfill area 1 68 is provided at a discharge end 1 69 of the second bleeder way section 1 66. The bleeder way 40 is then inclined upwardly in a third bleeder way section 70 which is connects to a fourth section of bleeder channel 172 that is downwardly dependent and is generally oriented vertically, which is connected to the sewage pipe 31. In the preferred embodiment, the toilet bowl 20 and the trap port 40 store approximately 1.9 liters of water. According to one of the advantages of the present invention, the bleeder way 40 has no reduction in transverse exit of its full length. In a preferred embodiment, each of the sections of the bleeder track 40 has a diameter outlet its full length of up to approximately 6.34 centimeters. As a result, the waste which is less than 6.34 centimeters in diameter can pass through there without obstructing the trajectory. Therefore, if some waste material goes to the path 40, it passes through there because the path 40 has no cross-sectional reduction. If any obstruction takes place in the toilet 10 of the present inventionThe blockage will occur in the pool and can be easily cleaned without the help of a plumber or cable. In addition, due to the lack of reduction of the diameter of the trajectory, an anti-clogging cable can easily pass through there. Therefore, the bleeder track design herein provides an outstanding scrap removal capability. In addition, this bleeder track design is provided for a discharge rate to the wastewater pipe of 4.2 liters / sec. Therefore, the total use of water per cycle of this toilet is 5.7 liters with 4.5 liters going towards the automatic discharge and 1.2 liters towards filling. The amount of total residual water in the pool after an automatic discharge operation is 0.7 liters. Figures 22-24 illustrate another embodiment of a toilet according to the teachings of the present invention that achieves an automatic unloading operation similar to that of Figures 1 -3. In this embodiment, the automatic discharge water flows through the edge channel 24a (designated by the arrow H) and the automatic discharge water flows through the spout channel 29a (designated by the arrow I) in opposite directions after which it is discharged from the transition path 22a. In spite of the fact that the automatic discharge paths are directed in this way, the hydraulic losses have been found to be minimal. Figure 25 illustrates another water flow path for a toilet according to the present invention wherein the flow of -27 -ag ua is directed in the same direction (see arrows J and K) to the edge channel 24b and the direct supplier channel 29b. In this embodiment, a part 1 76 of the transition path 22b is formed of a plastic insert. Figures 26 and 27 illustrate that the transition path and the direct jet path are formed at least in part from a plastic insert, such as 1 80. A first bin 1 82 is provided in the plastic insert 1 80 so that the automatic discharge water is directed towards the edge channel 24. A second runner 1 84 is provided at the end of the insert 180 in such a way that the automatic discharge water can be directed towards the base of the basin. The hydraulic losses, as they appear in the water flow path of Figure 28, are lessened by providing a uniform channel, the plastic insert 180, for transferring the spout water from the valve inlet 1 1 0 to the inlet 184 of the spout channel 29 around the beta cu. This uniform non-turbulent flow is improved by using the plastic, rubber or some other insertion material as it is meant for the more turbulent flow experienced in the water flow path of Figure 28. When fixing the insertion towards a finished China toilet , it results in a processing facility as well as. a more efficient and less expensive assembly. In accordance with the above, for these reasons established above, a toilet has been designed which achieves a higher energy output compared to existing toilets - 43 - to thereby provide greater water energy automatic discharge to remove waste of the toilet tub. In addition, the toilet complies with government agency requirements that mandate a minimum duration of "holding" the automatic discharge lever for one second and a maximum use of water of 1.6 grams (6 liters) / discharge. In addition, the toilet of the present invention improves the flow characteristics and flow capacity of the automatic discharge water and provides an automatic discharge operation that is completed in approximately 2.5 seconds (see Figure 29). In addition, the toilet's bleeder track design reduces clogging opportunities. Although the invention as particularly shown and described with reference to certain preferred embodiments, it will be readily apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention. It is intended that the appended claims be construed as being included in the foregoing as well as various other changes and modifications.
