DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first preferred embodiment of the toilet according to the present invention is illustrated in Figure 1 and is generally identified with the reference number 1. The toilet 1 comprises a frame 2. The frame 2 It is advantageously made of porcelain. However, other materials such as plastic and fiberglass can be contemplated. The frame 2 includes a toilet bowl 3, formed with a lower waste water discharge opening 4 oriented generally forward to discharge waste water 5 from the cup 3 in a generally forward flow. Under the toilet bowl 3, the frame 2 defines a hollow chamber 6. The hollow chamber 6 comprises a lower waste water discharge hole 7 connectable to a conventional drain pipe (not shown). As shown in Figure 1, the hollow chamber 6 defines a lower wall 8 which slopes towards the discharge hole 7, whereby the waste water discharged in the hollow chamber 6 falls on that lower wall 8 and flows towards the discharge hole 7 to be evacuated through this latter hole 7 and the drain tube (not shown) connected thereto.

Interposed between the cup 3 and the hollow chamber 6 is a tilting cup 9 made of any suitable material such as plastic, porcelain, fiberglass, resinous material, metal, etc. More specifically, the tilting cup 9 is pivotally mounted in the frame 2 around a horizontal, transverse axis 10. It should be understood that the tilting cup 9 can also be pivotally mounted on a different support surface of the frame 2. In the the non-inclined position of figure 1, the cup 9 follows the general profile of the toilet bowl 3 and therefore extends over the discharge opening 4 of the toilet bowl 3. As the cup 9 is not inclined, it is capable of containing water 5, which is communicated to the toilet bowl through the lower discharge opening 4. Of course, the cup 9 is large enough to retain a required level 11 of water 5 in the toilet bowl 3 , level 11 being sufficient to prevent the escape of gases from the waste water in the room in which the toilet is placed. The tilting cup 9 comprises a rearwardly extending tongue 12 formed with an upper cavity 13 in which a counterweight 14 is placed. The position of the shaft 10 and the mass of the counterweight 14 is selected to allow the counterweight 14 counter-balance the mass of water 5 and keep the cup 9 in the non-inclined position of figure 1. To operate the toilet 1, the user rotates a handle 15 to lift the rear free end 16 of the tongue 12 through a lever 17 and a chain 18. The cup 9 then tilts in the direction of the arrow 19 until it reaches an inclined position such as that shown in figure 5. Then, the waste water 5 from the cup 3 is discharged to through the opening 4, and then it is discharged from the cup 9 to the hollow chamber 6 to finally evacuate through the discharge hole 7 and the drain tube (not shown) connected thereto (see arrow 20 of figure 5) . In the inclined position of the cup 9 (see, for example, Figure 5), the counterweight 14 still produces a lever force tending to return the inclined cup 9 to its original non-tilted position of Figure 1. However, the return of the inclined cup 9 to its original non-inclined position of figure 1 is delayed for a given period of time by means of a piston device 21. As illustrated in figure 2 of the accompanying drawings, the piston device 21 it comprises a cylinder 22 having a lower end wall 23 pivotally connected to the frame 2 of the toilet 1 through a clamp 24 (see the mechanical link shown as a dotted line 25 in Figure 1). A piston 26 is slidably mounted in the cylinder 22, the impermeability of the joint between the peripheral edge surface of the piston 26 and the inner wall of the cylinder 22 being secured by a dynamic O-ring 27. A piston rod 29 has one end centrally secured from the face of the piston 26 opposite the lower end 23 of the cylinder 22 and a second end 36 pivotally connected to the rear free end 16 of the tongue 12 of the cup 9. The piston rod 29 passes through a hole 32 of the upper end wall 30 of the cylinder 22, the impermeability of the joint between the piston rod 29 and the hole 32 being secured by a dynamic O-ring 31. As can be seen in Figure 2, the piston 26 divides the internal volume of the cylinder 22 in upper chambers 33 and lower chambers 34. A conduit 35 of larger diameter allows easy transfer of air from chamber 33 to chamber 34 so as not to impede the movement of the chamber. lining of the cup 9 triggered by the action of the handle 15, the lever 17 and the chain 18. A check valve 37 is mounted in the duct 35 to allow only the flow of air from the upper chamber 33 to the lower chamber 34 A duct 38 of smaller diameter, provided with a snug fitter 39, also interconnects the upper 33 and lower chambers 34 of the cylinder 22. Upon returning the inclined cup 9 to its original non-inclined position of Figure 1 by the lever force produced by the counterweight 14, air is transferred from the lower chamber 34 to the upper chamber 33 of the cylinder 22. This air transfer can be carried out only through the conduit 38 of smaller diameter. The resistance to the air flow induced by the combined action of the small diameter of the duct 38 and the choke 39 encourages the pivotal movement of the cup 9, thereby delaying the pivotal movement, ie the return of that cup 9 to the position no. Of course, this period of time must be long enough to allow the waste water 5 to be evacuated from the cup 3, and allow cleaning of the cup 3 and the cup 9. Obviously, the piston device 21 can be replaced by any other mechanism capable of carrying out the same function. Similarly, it can also be understood that the combination of handle 15, lever 17 and chain 18 can be easily replaced by other trigger systems, such as electrical, electronic or pneumatic systems. Referring again to Figure 1, the toilet bowl 3 defines an upper hollow rim 40 defining a lower annular flange 41 located inside the bowl 3.

Emerging from the flange 41 are peripherally distributed nozzles 42 directed towards the inner wall of the toilet bowl 3. When the cup 9 is tilted from the position of Figure 1 to an inclined position such as that shown in Figure 5, a sequential valve 43 (Figure 1) is supplied with water through an inlet tube 44 to sequentially supply the nozzles 42 with this water through the outlet tubes 45. An example of a sequential valve is illustrated in Figure 3. The sequential valve 43 of Figure 3 comprises a housing 46 and a cover 47 for closing said housing 46 and forming a waterproof housing. The water supplied to the sequential valve 43 through the inlet tube 44 drives a water turbine 48. An internal semi-ciar wall 49 of the housing 46 biases the flow of water entering the housing 46 through the conduit 44 to drive in Efficiently form the turbine 48. The rotational movement of the turbine 48 is transmitted to a sprocket 50 of smaller diameter in toothed engagement with a sprocket 51 of larger diameter. The rotational movement of the gear 51 is finally transferred to a water distribution disk 52. The water distribution disk 52 is applied to the lower face 53 of the housing 46. The water distribution disk 52 is provided with one or more pairs of diametrically opposed holes 54, while the lower face 53 of the housing 46 is provided with several pairs of diametrically opposed holes 55, each connected to a corresponding outlet tube 45. Upon rotation of the disk 52, the pair of holes 54 becomes successively and sequentially aligned with each pair of holes 55 diametrically opposite. The nozzles 42 are therefore supplied with water from the housing 46 by means of the pairs and sequentially to produce sequential water jets whose function is to clean the inner wall of the toilet bowl 3 and the interior of the cup 9. It should be understood that the placement and number of holes 54 in the dispensing disc 52 and the holes 55 in the housing 46 can be varied at will to obtain any desired sequence and number of water jet streams out of the nozzles 42. From then, the water distribution disk 52 can be replaced by any , -. other types of valves capable of performing the same function, such as piano keys. Those skilled in the art will appreciate that the orientation of the nozzles 42 is selected to optimize the cleaning of the internal walls of the toilet bowl 3 and the interior of the cup 9. For the same purpose, the nozzles 42 can be designed to produce ciar, oval and / or flat water jet streams. Likewise, the toilet can be provided with stationary, moving nozzles 42 that undergo translation, pivots and / or swivels. Of course, the water supply to the inlet tube 44 can be controlled both electronically and mechanically. As an example, a float valve 56 is mounted in the cup 9 outside the cup 3 and responds to the fact that the water level 5 falls below the level 11 as the cup 9 tilts towards the position of Figure 5, to supply water from a water source 57 to the inlet tube 44 of the sequential valve 43. In the same way, after the cup 9 has returned to the non-inclined position of Figure 1, the float valve 56 detects that the water 5 has reached level 11 to interrupt the supply of water from the water source 57 to the inlet pipe 44. Of course, it is within the scope of the present invention to replace the float valve 56 with any electronic devices and / or mechanics capable of carrying out the same water supply control operation. Similarly, to compensate for the excessive level of water in stationary operation, a small hole in the cup 9 can be provided at an appropriate level to drain the excess water. The operation of the toilet 1 of figure 1 therefore involves the following steps: (a) the handle 15 is manually turned to cause the inclination of the cup 9 from the position of the figure I to a tilted position such as that of Figure 5; (b) the waste water from the cup 3 and the cup 9 is discharged into the hollow chamber 6 and then evacuated through the discharge hole 7 and the drain tube (not shown); (c) the water level reduction 5 below the level II is detected by the float valve 56; the float valve 56 then supplies water from the water source 57 to the sequential valve 43 through the inlet pipe 44; (d) the sequential valve 43 supplies water to the nozzles 42 in pairs and sequentially through the outlet tubes 45 to produce sequential water jet streams to clean the inner wall of the toilet bowl 3 and the cup 9; (e) the inclined cup 9 is returned to the non-inclined position of Figure 1 by the lever force produced by the counterweight 14, this pivotal movement being encouraged by the action of the piston device 21; (f) by pivoting the inclined cup 9 about the axis 10 to return to the position of Figure 1, the cup is gradually filled with water from the nozzles 42; and (g) when the cup 9 has returned to the position of figure 1 and the water from the nozzles 42 has filled the cup 9 to level 11, the float valve 56 is turned off and the sequential valve 43 is no longer supplied with Water. The toilet 1 is then ready to be operated again by the manual operation of the handle 15. Referring now to FIG. 1, it is also within the scope of the present invention to replace the assembly of the handle 15, the lever 17 and chain 18 with an electric trigger system. In such a system, the rod 12 of the cup 9 is properly weighed with the counterweight 14 to polarize the position of the cup 9 in a first non-tilted position. When the cup is sufficiently filled with water and waste products (partially), the cup 9 will automatically begin to tilt due to gravity upon exceeding the weight of the cup 9 and its contents the weight of the counterweight 14. Accordingly, as such system, the handle 15, the lever 17 and the chain 18 are replaced with a single push button trigger 15 ', and optionally a remote control unit (not shown) that activates an electronic control unit 17', which in turn activates a valve for supplying water from a water source 57 to the inlet tube 44 of the sequential valve 43. Sequential water jet streams are then expelled into the inside wall of the toilet bowl 3 and inside the cup 9 to gradually fill cup 9 to a level of three quarters full so that it automatically tilts, as described above. When inclined, the cup 9 will assume a second position, namely the inclined position shown in Figure 5. Through all this tilting movement of the cup 9, the nozzles 42 will continue to expel water on the inner surface of the cup 3 and the cup 9. Delay means such as the piston device 21 described above can be provided to delay the return of the cup 9 to its non-inclined position. With or without delay means, the cup 9 will automatically resume, of course, its first non-tilted position due to the counterweight 14. The electronic control unit 17 'is of course programmed to effect sequential and timed sprinkling of the nozzles 42 to perform a thorough rinsing of the cup 3 and the cup 9. In an optional embodiment, the electronic control unit 17 'can be programmed to repeat the cycle described above, namely to fill the cup 9 a about three quarts full this time with fresh rinse water to thoroughly clean cup 3 and cup 9, which will once again lean to the second position shown in figure 5, will return to its original non-inclined position shown in figure 1, and finally it will be filled with water at a predetermined level, as described in relation to figure 1, to prevent the escape of gases from the waste water of the drainage hole 7. This final step will place the toilet 1 in its waiting position. A second preferred embodiment of the toilet according to the present invention, generally identified with reference numeral 60, will now be described with reference to Figures 4-8 of the accompanying drawings. It should be noted that the corresponding elements of the first and second toilet embodiments according to the invention are identified with the same reference numerals. With reference to Figure 4, the toilet 60 comprises a frame 2. The frame 2 is advantageously made of porcelain. However, other materials such as plastic and fiberglass can be contemplated. The frame 2 includes a toilet bowl 3 formed with a lower waste water discharge opening 4, generally facing forward to discharge waste water 5 from the bowl 3 in a generally forward flow. Under a toilet bowl 3, the frame 2 defines a hollow chamber 6. The hollow chamber 6 comprises a lower waste water discharge hole 7 connectable to a conventional drain pipe (not shown). As shown in FIG. 4, the hollow chamber 6 defines a lower wall 8 which slopes towards the discharge hole 7, whereby the waste water discharged in the hollow chamber 6 falls on that lower wall 8 and flows towards the discharge hole 7 to be evacuated through this latter hole 7 and the drain tube (not shown) connected thereto. Interposed between the cup 3 and the hollow chamber 6 is a tilting cup 9. More specifically, the tilting cup 9 is pivotally mounted in the frame 2 around a transverse, horizontal axis 61. In the non-inclined position of the 4, the cup 9 follows the general profile of the toilet bowl 3 and therefore extends over the discharge opening 4 of the toilet bowl 3. As the cup 9 is not inclined, it is capable of containing water 5, the which is communicated to the toilet bowl 3 through the lower discharge opening 4. Of course, the cup 9 is large enough to retain a level 62 of water 5 in the toilet bowl 3. With reference to figures 4 and 6, the tilting cup 9 is formed with a pair of integral, lateral, symmetrical water tanks, of which only the left tank 63 is illustrated. The tank 63 is supplied with water through a tube 64 shown in line dotted in figure 4. The deposit 63 ta Also comprises a lower orifice 65. The preferred embodiment of Figure 4 uses a bolt mechanism 66 operated by a float, polarized by means of a spring. In this preferred embodiment, the tilting cup 9 does not include a rearwardly extending tab, but a trailing edge 67. The mechanism 66 comprises a V-shaped arm 68 pivotally mounted on the rear edge 67 of the cup. which is inclined 9. At the end of the V-shaped arm 68 located inside the cup 9, a float 69 is mounted. A bolt 70 is formed on the other end of the V-shaped arm 68 located outside the cup 9. The bolt 70 links a hook element that links bolt 71 formed integral with the frame 2 of the toilet 60 to hold the cup 9 in the position of Fig. 4. A spring element 72 normally applies the bolt 70 to the hook element 71 As illustrated in Figure 4, the toilet bowl 3 defines an upper hollow rim 40 defining a lower annular flange 41 located inside the cup 3. Emerging from the rim 41 are the peripherally distributed nozzles 42 directed towards the body. internal network of the toilet bowl 3 and supplied with water through respective outlet tubes 73 of a control valve device 74.

As will be explained in the following description, the operation of the toilet 60 is controlled by a valve device 74. In order to operate the toilet 60, the user only has to press a push button 75 (figure 4). Referring now to FIGS. 7 and 8, the control valve device 74 comprises a sawtooth wheel 76 surrounded by a generally rectangular ring 77 in cross section. Pivotally mounted in an internal cavity 78 of the ring 77 is a spring-biased ratchet 79. More specifically, the ratchet 79 has a proximal end pivotally mounted about an axis generally parallel to the axis of rotation 80 of the sawtooth wheel 76. A spring 81 interposed between the lower part of the cavity 78 and the pivotal ratchet 79 urges the free distal end 83 of this pawl 79 on the saw teeth, such as 82, of the wheel 76. The push button 75 comprises a rod 84 passing through an upper wall 89 of the frame 2 and extending towards the control valve device 74. A connecting rod 85 (FIG. 8) has a first end 86 pivotally connected to the end of the rod 84 opposite the push button 75, and a second end 87 pivotally connected to the outer peripheral edge face 88 of the ring 77. By depressing the push button 75, the longitudinal movement of the rod 8 4 is transmitted through the connector rod 85 to rotate the ring 77 about the shaft 80 in the direction 90. The rotational movement of the ring 77 is then transmitted to the sawtooth wheel 76 through the ratchet 79, whose end 83 is by linking a saw tooth 82. When the push button 75 is released, this push button returns to its non-depressed position (by the action of a spring (not shown), for example). The ring 77 then rotates in the direction opposite to the direction 90 and the spring-biased ratchet 79 slides on the sawtooth 82 to link another tooth 82 upstream. The rotational movement of the sawtooth wheel 76, caused by the pressing of the push button 75, is transmitted to another sawtooth wheel 91 through an arrow 92. As illustrated in FIGS. 9a and 9b, the wheel 91 comprises a peripheral annular rim surface 94 divided into an annular, smooth axial portion 95 and an annular, serrated axial portion 96. The annular, smooth axial portion 95 defines a cam section 96 and a semi-circular section 121 (FIG. 9a). As shown in figure 8, the wheel 76 and the ring 77 can be located outside a waterproof housing 93 of the control valve device 74, while the wheel 91 is located within that housing 93. Water is supplied to the control valve device 74 from a water source 98 through of an inlet pipe 99 (figure 4), and then through a spring-biased valve 100 (see arrow 101 in figure 7). The valve 100 comprises a tubular member 102 defining a tapered seat 103, and a plug member 104 defining a tapered surface 105 that fits in the tapered seat 103 and applied to that seat 103 by means of a spring 106. A ring in O 107 ensures the impermeability of the joint between the seat 103 and the conical surface 105. The plug element 104 comprises an integral extension 108 which extends within the housing 93 and having a rounded free end 109 applied to and sliding over the annular axial portion. , smooth 95 of the wheel 91. Initially, this rounded free end 109 of the extension 108 is in the position shown in Figure 9a, ie at the corner 110 of the cam section 97. The rotational movement of the wheel 91 in the direction 111 (figure 9a) imparted by the depression of the push button 75, causes the free end 109 to slide on the cam section 97 and the axial movement of the extension 108 against the force produced by the spring 106. The conical surface 105 is then separated from the conical seat 103, with which water enters through the valve 100 and flows through a conduit 112 formed within the housing 93 to drive a turbine 113 The conduit 112 comprises a semi-circular wall 114 for diverting the flow of water so as to efficiently drive the turbine 113.

The rotational movement of the turbine 113 is transmitted to a speed reduction gear system 115 via an arrow 116. The engagement system 115 is located in a waterproof compartment 117 of the housing 93, thereby water does not reach the sawtooth wheels of that engagement system 115. The speed reduction gear system 115 comprises a gear 118 which is rotated through "•" "- the rotation of the turbine 113. The toothed wheel 118 is mounted on an arrow 119 that rotates therewith to drive a wheel ratchet mechanism 120 which links the teeth of the annular, toothed axial portion 96 of the wheel 91 for rotating this wheel 91 at a given speed in the direction 111.

This type of ratchet mechanism is well known to those skilled in the art and accordingly will not be described herein further. Therefore, by rotating the gear 118 to drive the ratchet mechanism 120 and rotate the wheel 91 in the direction 111, the rounded free end 109 of the plug member 104 first slides over the cam section 97 of the annular axial portion. , smooth 95 of the annular rim surface 94 of the wheel 91 to gradually open the valve 100, and then on the semi-circular section 121 in which the valve 100 is fully open. Meanwhile, the water in the duct 112 that has driven the turbine 113 fills the housing 93 and is supplied to a compartment 122 of that housing 93 through a hole 123 in a partition wall 124 (see Figure 7). Also, the speed reduction gear system 115 comprises a gear wheel 125 to which rotation is imparted upon rotation of the turbine 113. The gear wheel 125 is mounted on a tubular shaft 126 which rotates therewith and passes through the a dividing wall 127 located between compartments 117 and 122. The rotational movement of the sprocket 125 is transmitted, through the arrow 126, to a sprocket 128 of smaller diameter in engaged engagement with a larger diameter sprocket 129 , the wheels 128 and 129 being both mounted in the compartment 122. The rotational movement of the sprocket 129 is finally transferred to a water distribution disc 130. Referring to FIGS. 7 and 10, the water distribution disc 130 is applied to a wall surface 131 of the compartment 122. The water distribution disk 130 is provided with a pair of diametrically opposed holes 132 while the surface ie wall 131 of compartment 122 is provided with several pairs of diametrically opposed holes 133, each connected with a corresponding outlet tube 73 of control valve device 74. Upon rotation of disc 130, the pair of holes 132 it becomes successively and sequentially aligned with each pair of diametrically opposed holes 133. The nozzles 42 are therefore supplied with water from the housing 93 in pairs and sequentially to produce sequential water jet streams whose function is to clean the inner wall. of the toilet bowl 3 and the interior of the bowl 9. The water distribution disc 130 is additionally provided with a semi-circular oblong hole 134 associated with a hole 135 of the wall surface 131. The hole 135 ; '- is connected to the tube 64 (figure 4) which supplies the water tank 63 on both sides of the cup 9. Therefore, the rotational movement of the wheel 91 in the direction 111 (figure 9a) imparted by the pressing of the button The thrust 75 causes sliding of the free end 109 on the cam section 97 and axial movement of the extension 108 against the force produced by the spring 106 to allow water to flow through the conduit 112 and drive the turbine 113. The rotational movement of the the turbine 113 is transmitted to the speed reducing gear system 115 to rotate the sprocket 125, the rotational movement of the wheel 125 being transmitted to the water distribution disc 130 to supply the nozzles 42 with water from the housing 93 in pairs and sequentially to produce the sequential water streams that clean the cup 3 and the cup 9. The water from the nozzles 42 raises the level of the water 5 in the toilet bowl 3 from an initial level 136 to the level 62, the level 136 being sufficient to prevent the escape of the gases from the waste water into the room in which the toilet is installed. Meanwhile, when the oblong hole 134 of the water distribution disc 130 is aligned with the hole 135 of the wall surface 131, water is supplied to the two side reservoirs, such as the reservoir 63, through the tube (s) associated (s), such as the tube 64. The tube or tubes 64 pass close to the shaft 61 and are flexible to prevent these tubes "-" from obstructing the tilting movement of the cup 9. When the water 5 has reached the level 62, the side tanks such as the reservoir 63 are filled with water.Further, the float 69 responds to that water level to pivot the V-shaped arm 68 and thereby disengage the bolt 70 from the hook element 71. cup 9 then tilts in the direction of arrow 137 (figure 4) until it reaches the inclined position of figure 5. Then, waste water 5 from cup 3 is discharged through opening 4, and then discharge of the cup 9 into the hollow chamber 6 to be evacuated finally through the discharge hole 7 and the drain pipe (not shown) connected thereto (see arrow 20 of figure 5). In the meantime, the nozzles 42 continue to be supplied with water to produce sequential water streams of water, and the water of the two reservoirs such as the reservoir 63 is gradually discharged through the corresponding lower orifice 65. When water is discharged from the reservoirs, such as the reservoir 63, through the lower orifices 65, the center of gravity of the cup 9 and its contents move backwards, whereby the cup 9 slowly pivots about the axis 61 towards the original non-inclined position of Figure 4, until the spring-biased latch 70 links the hook element 71. This action delays the return of the cup 9 to the non-tilted position for a predetermined period of time to allow proper evacuation of the waste water and the cleaning of the cup 3 and the cup 9. The cup 9 can be structured to obtain this translation of the center of gravity. Alternatively, counterweights may be added as required to obtain this operation. During the return of the cup 9 to the non-inclined position of figure 4, and after the cup 9 has returned to the non-inclined position of figure 4, the water jet streams of the nozzles 42 raise the water level in the cup 9 and the toilet bowl 3. The rotation speed of the wheel 91 driven by the speed reducing gear 118, the arrow 119 and the ratchet mechanism is adjusted as a function of the water pressure of the source 98 to fill cup 3 and cup 9 to level 136 of figure 4. More specifically, when water level 5 reaches level 136, rounded free end 109 of extension 108 of plug member 104 leaves end 139 ( 9a) of the semi-circular section 121 of the annular, smooth axial portion 95 of the annular rim surface 94 of the gear 91 fall into the corner 110. Then, the ring in 010 seals the joint between the conical seat 103 and the conical surface 105, whereby it is no longer it supplies water to the housing 93 through the valve 100, thereby stopping the operation of the turbine 113 and therefore the operation of the toilet 60, until the push button 75 is pressed again to trigger the cycle of operation of the toilet 60 described above. Figure 11 illustrates the lower waste water discharge hole 7 located in front of the hollow chamber 6 to facilitate the evacuation of waste water from the cup 3 and the cup 9. A disadvantage of the embodiment of Figure 11 is that it does not meet the construction standards currently in force. Nevertheless, it would be easy in new buildings to displace the drain pipe (not shown) to receive the lower waste water discharge hole 7 of Figure 11. In Figure 12, an alternative construction of the cup 9 is illustrated. Cup halves 167 and 168, both bowing as shown on the dotted line to discharge wastewater. A disadvantage of this alternative is that a waterproof seal 169 is required between the two halves 167 and 168 to maintain the water in the cup 9. To facilitate the manufacture and maintenance of the non-flooded toilet according to this invention, can be made of three pieces, as illustrated in figure 13: a frame 170 defining a hollow chamber 172 with a waste water discharge hole 171 connectable to the drain pipe (not shown), and an upper flange 173; a toilet bowl 175 formed with a periphery flange 176 to be mounted on the upper flange 173 with a rubber gasket 177 between the flange 173 and the flange 176; and a sloping cup 174 pivotally mounted in the frame 179 or the cup 175.
