    [0002] Flush mechanism for toilet cistern
    [0004] Technical field of the invention
    [0006] The present invention corresponds to the technical field of toilet tanks, specifically to a flush mechanism for said tank, where the tank has a water inlet with a filling valve connected to a float or float, and a flush button.
    [0008] Background of the Invention
    [0010] At present, toilet cisterns all have a water storage tank or volume intended for discharge at the time it is required, in order to produce the dragging of the remains and waste accumulated in the toilet bowl.
    [0012] The cisterns have a water inlet mechanism, which is responsible for recharging the water in the storage volume after each use, so that it is kept in optimal conditions for the moment when it is necessary to operate the tank again. mechanism. This mechanism features a series of gaskets to prevent leaks.
    [0014] For its part, the cistern discharge mechanism has the function of opening the water outlet space to empty the tank, that is, to empty the water tank. In this sense, the flush mechanism can be actuated by a button or, in the case of older cisterns that are hung on the wall above the toilet, by a handle. In either case, the mechanism is similar.
    [0016] Said discharge mechanism is formed by a discharge valve that is adjusted to a water outlet hole at the bottom of the tank and has an upward and downward movement activated by the push-button, which allows or prevents, respectively, the exit of the water by the same.
    [0018] This valve has several gaskets, including a joint that connects to the outline of the outlet orifice that prevents any type of leakage through it.
    [0019] This type of discharge mechanism is usually associated with inconveniences that increase in number and frequency over time.
    [0021] One of the reasons is that the mechanism is submerged inside the water tank itself, so that continuous contact with it accelerates the wear processes of the gaskets, for example, causing leaks in it. These leaks are usually accompanied by a constant and repetitive noise that is very annoying for any user, in addition to generating a waste of such a scarce good as water, from which very high volumes are lost due to these reasons.
    [0023] Thus, among the problems presented by this type of discharge mechanism is the deterioration of the sealing gasket due to deterioration due to contact with water and with the lime it presents.
    [0025] Another drawback is due to the passage of water from the cistern to the toilet. This is located at the bottom of the cistern and allows the passage of water when the discharge mechanism moves upwards, leaving it free.
    [0027] Therefore, it presents exit conditions, caused by the opening of the bottom opening, in which the unloading mechanism is fitted, which in practice results in a low drag force.
    [0029] This problem appears in many toilets, in which the user observes that the remains are not completely eliminated, which is why he is forced to make a new flush, which multiplies the consumption of water, this being a serious inconvenience for conservation enviroment.
    [0031] Description of the invention
    [0033] The flush mechanism for a toilet cistern, where said cistern comprises a water inlet with a filling valve connected to a float or float, and at least one first flush button, which is presented here, is formed by at least one first unloading module comprising at least one first tank located inside the tank, connected to it by means of a rotation axis, and which is formed by a body with an opening in an area thereof, capable of presenting a first movement of rotation around the axis inside the tank, with a minimum angle such that it allows gravity discharge of at least part of the first tank.
    [0035] This first tank has a first position in which the opening is located at the upper level of the same for filling and a second position in which the opening is located at a level equal to or less than the level of the contained water sheet. in said first deposit.
    [0037] Likewise, the discharge mechanism has means for controlling the position of the first tank, formed by at least one first tab located inside the tank, facing the first tank, and a first tab located on the outside. of the lateral surface of the same, so that, in the first position of the first reservoir, the first tab has a position as a stop, located in contact with the first flange and opposite it, according to the direction of the first turning movement .
    [0039] Furthermore, the first tab is connected to the first flush button that is arranged on the side of the tank and has a withdrawn position with respect to the first tab, associated with the activation of said first button, such that it allows the tab to pass through and the first turning movement of at least the minimum angle, of the first deposit.
    [0041] A significant improvement in the state of the art is obtained with the toilet cistern flush mechanism proposed here.
    [0043] This is so because a mechanism is achieved in which rubber gaskets are not necessary, neither in the flush mechanism itself, nor in the union of the cistern to the toilet, thus eliminating the problem of possible annoying leaks.
    [0045] Neither will there be leaks due to the screws that hold the tank to the bowl, as the water is not directly in the tank but in a tank inside it, so these screws are not in contact with the water. nor will they have problems of limescale build-up in them. In fact, lime is no longer a problem in this mechanism, since the elements of the discharge mechanism are outside the tank and therefore out of contact with the water.
    [0047] By not presenting leaks, a very important saving of water is achieved, with the consequent benefit for the environment, in addition to a reduction in the consumption costs of the herself. Likewise, the annoying repetitive noise caused by these losses and the stains that are produced on the surface of the toilet due to the continuous contact of the lime hitting the same place are avoided.
    [0049] It is a mechanism of great simplicity, with a low manufacturing cost, which also allows greater ease of repair, as well as replacement if necessary, being able to repair it by the user himself in a few seconds. It is only necessary to remove the upper cover that is held by gravity, since it does not house any button, and remove the tank from its support. In the event that the tap of the water inlet were disturbed for said extraction, it would be installed subject to a small removable portion of the wall of the cistern, which would be extracted together with the tap connected to its hose.
    [0051] Actually, it requires little or no maintenance and, if needed, it is very simple, given the total absence of joints and connections between the tank and the mechanism. It is a much more robust mechanism with greater durability.
    [0053] Another great advantage that it presents is that it achieves a greater drag effect for the same volume of discharge water, since the way in which said discharge occurs, by overturning the tank, generates a falling speed of the water that allows an effective drag of existing waste in the toilet.
    [0055] In addition, the height of the tank with respect to the toilet can be varied to achieve greater speed and force in the fall of the same.
    [0057] On the other hand, the tank position control mechanism, connected to the first pushbutton, is easy to activate, since the tanker tongue only retains the tendency of the tank to rotate, so the first pushbutton does not require a great effort of pressing and this favors the use of the cistern for older people or with some mobility problem.
    [0059] In addition, the mechanism is formed by at least one discharge module, where this module can comprise one or two complementary tanks, so that the discharge of one of them coincides with the filling of the other tank, so that a way of easier and more efficient repositioning.
    [0060] It also allows the option of controlling the discharge volume, by means of a partial discharge of the volume stored in the tank, when the toilet has been used for smaller waters and, a total discharge of said volume, when the remains that are desired drag correspond to larger waters. This achieves significant savings in water consumption.
    [0062] This effect of partial or total discharge can also be achieved with the option of a first and second twin discharge modules, so that both work in parallel, each one with the tank (s) that form it, its loading tap, its float. , its retention tab and its button. These pushbuttons are arranged very close horizontally or vertically, so that a single pushbutton can be actuated to discharge a tank from a first discharge module, or the two pushbuttons simultaneously, with which the discharge of the deposits of both modules.
    [0064] It is therefore a very efficient tank flush mechanism, which manages to solve current problems in a simple and convenient way to use.

    [0089] Detailed description of a preferred embodiment of the invention
    [0091] In view of the figures provided, it can be seen how in a first preferred embodiment of the invention, the flush mechanism for a toilet cistern, where said cistern (2) comprises a water inlet (14) with a filling valve connected to a buoy (15) or float, and at least one first discharge button (8) proposed here, is formed by at least one first discharge module comprising at least one first tank (1) located inside of the cistern (2), connected to it by means of a rotating shaft (3), and which is formed by a body with an opening (4) in an area thereof, capable of presenting a first rotating movement (5) around the axis (3) inside the tank (2), with a minimum angle such that it allows the discharge by gravity of at least part of the first tank (1).
    [0092] As shown in Figures 1 and 2.1, the first tank (1) has a first position in which the opening (4) is located at the top of the tank for filling, and a second position, which can be seen in the Figure 2.3, in which the opening is located at a level equal to or less than the level of the water sheet contained in the first tank (1).
    [0094] In this first preferred embodiment of the invention, as shown in Figure 1, the discharge mechanism comprises a first discharge module with a single first semi-cylindrical tank (1), with two bases (1.1) arranged vertically , a lateral surface (1.2) between the two and an open flat face that corresponds to the opening (4).
    [0096] In this case, the shaft (3) is arranged at an intermediate height of the first tank (1) and eccentrically with respect to its center of gravity in a fully loaded position. Likewise, the first tank (1) has a maximum angle of rotation determined in the second position, less than 180 °.
    [0098] Furthermore, in this first embodiment, the mechanism has a second turning movement (5.2) in the opposite direction to the first turning movement (5.1), to return the first tank (1) to the first position, as can be seen in the Figures 3.1 to 3.4.
    [0100] The unloading mechanism in turn comprises means for controlling the position of the first tank (1).
    [0102] Said control means are formed by at least a first tab (6) located inside the tank (2) and oriented towards the first tank (1) and a first flange (7) arranged on the outside of the lateral surface of the first tank (1), so that, in its first position, as shown in Figures 1 and 2.1, the first tab (6) has a position as a stop, located in contact with the first tab ( 7) and in front of it, according to the direction of the first turning movement (5.1). In this way, when the first tank (1) is in that first position, the first tab (6) prevents the passage of the first flange (7) and keeps the first tank (1) at rest.
    [0104] On the other hand, the first tab (6) is connected to the first discharge button (8), which is arranged on the side of the tank, so that, as shown in Figure 2.3, in which the second position of the first tank (1) is represented, when this first push-button (8) is activated, the first tab (6) presents a withdrawn position with respect to the first tab (7), associated with said activation of the first pushbutton (8), such that it allows the passage of the first flange (7) and the first turning movement (5.1) of the first tank (1), turning at least the minimum angle.
    [0106] In a preferred embodiment in which the discharge can only be carried out completely, the means for controlling the position of the first tank (1) would be as defined up to now, with a first position of the first tank (1 ) as represented in Figure 2.1 and a second position as represented in Figure 2.3.
    [0108] However, in this first preferred embodiment of the invention, the means for controlling the position of the first tank (1) also comprise an additional flange (27) located on the outside of the lateral surface (1.2) of the first tank (1) so that in its first position it is arranged at a lower elevation than the first flange (7).
    [0110] Thus, as shown in Figure 2.2, the first tank (1) has an intermediate position, with an intermediate angle of rotation of a value greater than or equal to the minimum angle and less than the maximum angle, in which the first tongue (6) is positioned as a stop, in contact with the additional flange (27) and in front of it, according to the direction of the first turning movement (5.1).
    [0112] In other words, in this case, the cistern has a possibility of partial discharge and complete discharge. Therefore, the first activation of the first pushbutton (8) generates the withdrawal of the first tab (6) allowing the passage of the first flange (7) and with it the first deposit initiates the rotation of an angle between the minimum angle and the maximum angle, since after said first press, the first tab (6) returns to its original position so that, during the rotation of the first tank, it is on this occasion the additional flange (27) that meets the obstacle formed by said first tab (6), which prevents the complete rotation from continuing, as shown in Figure 2.2. With this, a partial discharge of the tank is produced, which is very appropriate for the removal of minor waters.
    [0113] On the other hand, an additional pressing of the first button (8), or in its case, a pulsation maintained over time, again generates the withdrawal of the first tab (6), as shown in Figure 2.3, allowing in this case the passage of the additional flange (27). In this way, the continuation of the first turning movement (5.1) of the first tank (1) is allowed, up to the maximum angle of rotation, that is, up to the second position in which the complete discharge of the tank occurs, necessary to the dragging of the major waters.
    [0115] Once the first tank (1) has reached the second position and discharges the water it contained, the second turning movement (5.2) begins, as shown in Figures 3.1 to 3.4, until reaching the first position of the first tank (1). To allow this turning movement back to the first position, the first tab (6) must be removed again to allow the passage of the additional flange (27) when it is again in the second turning movement (5.2), recovering its position automatically after the passage of the additional flange (27) by means of a built-in spring device.
    [0117] To ensure that the return to the first position takes place, the first discharge module comprises means for activating said return to the first position of the first tank which, in this first preferred embodiment of the invention, are formed by an element stop (9) inside the tank (2) and a second flange (10) arranged on the outside of the lateral surface (1.2) of the first tank (1) so that, in the second position with the angle maximum rotation, as shown in Figure 2.3, said second flange (10) is in contact with the stop element (9).
    [0119] In this case, in addition, said means for activating the return to the first position comprise a spring (11) on the stop element (9), arranged such that in the second position, the spring (11) is compressed between the second flange ( 10) and said stop element (9).
    [0121] In other embodiments, the means for activating the return to the first position may comprise a spring (11) fixed at one end to the interior surface of the tank (2) and at the other end to the exterior of the side surface (1.2) of the first tank (1) and such that the spring (11) is in a traction situation in the second position of the first tank (1).
    [0122] In said first position, the first tank (1) is filled with water and waiting for an activation of the first push-button (8) to start the first turning movement (5.1). At that moment it rotates to the intermediate position and subsequently to the second discharge position. When the first tank (1) returns to the first position after having made a discharge, in principle it is empty and when it reaches the first position the water inlet is activated to it, to refill it with water waiting for a new download.
    [0124] In this first embodiment, the means for activating the return to the first position are also formed by at least one counterweight fixed to the lateral surface (1.2) of the first tank (1) in the interior zone thereof, in the zone of the same closer to the axis (3) of rotation. In this way, when the first tank (1) reaches the discharge position and is completely emptied, as shown in Figure 2.3 and 3.1, this counterweight exerts a force in the direction of the second turning movement (5.2), which generates the beginning of the same to return to the first position.
    [0126] In this case, the counterweight is formed by a complementary tank (12) closed with water inside. This complementary tank (12) filled with water, has a cap with which it can be filled in more or less quantity, to obtain a fine adjustment of the turning movement of the first tank (1).
    [0128] Likewise, in this preferred embodiment, the means for activating the return to the first position are formed by at least one auxiliary open tank (13) arranged on the lateral surface (1.2) of the first tank (1), where the inlet (14) of water and said auxiliary tank (13) are vertically aligned at least in a moment of the second rotational movement (5.2) of the first tank (1), and the auxiliary tank (13) has an opening (13.1) with a inclination such that it is oriented towards the water inlet (14) at that moment when both coincide.
    [0130] In this case, as shown in Figures 3.1 to 3.4, the mechanism comprises four open auxiliary tanks (13), located on the outside of the lateral surface (1.2) of the tank and an auxiliary tank (13) open on the side. interior of said lateral surface (1.2), although in other embodiments they may be arranged only outside or only inside the first tank (1).
    [0131] These auxiliary tanks (13) in this case are located in such a way that when the first tank (1) reaches the second position and after unloading, one of these auxiliary tanks (13) is aligned with the water inlet (14) , so it begins to fill up, as shown in Figure 3.1. The weight of the water that this auxiliary tank (13) will contain causes, together with the other activation means, the return of the first tank (1) to the first position, by means of the second turning movement (5.2), which as it advances , is positioning the rest of the auxiliary tanks (13) aligned with the water inlet (14), as shown in Figures 3.2 to 3.4, while the auxiliary tank (14) that has previously been aligned, is inclined enough to to drop the water. Therefore, a Ferris wheel effect is generated.
    [0133] In other embodiments, as the activation of the return already has the counterweight, which in this case is formed by a complementary tank (12), it is possible that the auxiliary tank (s) (13) do not coincide with the input (14) of the water at the moment of the second position, but during some intermediate position of the second turning movement (5.2).
    [0135] In this first embodiment, the three types of activation means proposed are used, but in other embodiments, only the one consisting of a counterweight or this combined with one of the other two types may be used. Any other type of activation means that seeks the same effect can also be used, for example, the aforementioned option of a spring hooked on the tank and the tank so that it stretches when the discharge turns and after that, pull the tank. to return it to its initial position, or the activation of counterweights connected to the rotating tank by means of a cable or lever that exerts the same effect.
    [0137] In this first embodiment, the valve (16) for filling the water inlet (14) connected to the buoy (15) is arranged close to the side of the tank (2) towards which the first turning movement is carried out. (5.1), so as not to pose an obstacle during it. In other embodiments, said valve may be in a sufficiently high position so as not to interfere with the rotation of the tank and on the position of the float fixed to the inside of the tank, with its own arm for actuating the arm that controls the filling valve.
    [0139] In a second preferred embodiment of the invention, the discharge mechanism is formed by a discharge module comprising a first tank that has a shape whose section is triangular, as shown in Figures 4.1 to 4.3, with a first leg located in the upper part that forms the flat face in which the opening (4) is located and two legs arranged in a lower way to the previous one that make up the lateral surface (1.2) of the first tank (1).
    [0141] The position control means, in this second embodiment, are similar to those of the first previously proposed embodiment, therefore it presents the option of partial discharge, shown in Figure 4.2, and full discharge, represented in Figure 4.3.
    [0143] Furthermore, in this case, the means for activating the return to the first position shown in Figure 4.1, are formed by at least one open auxiliary tank (13) arranged on the side surface (1.2) of the first tank (1) , where the water inlet (14) and said auxiliary tank (13) are vertically aligned at least in a moment of the second rotational movement (5.2) of the first tank (1), and the auxiliary tank (13) has an opening ( 13.1) with an inclination such that it is oriented towards the water inlet (14) at that moment when both coincide. In this way, when the first tank (1) is in the second position, as shown in Figure 4.3, the entry of water into the auxiliary tanks (13) activates its return to its first position to start again. its filling.
    [0145] In a third preferred embodiment of the invention, the discharge module comprises first and second tanks (1, 20) of semi-cylindrical shape, in which the flat face configures the corresponding opening (4) of each tank and they are joined in the area of the lateral surface (1.2, 20.2) furthest from said opening (4), where the axis (3) of rotation is located in the center of the junction between both first and second tanks (1, 20).
    [0147] In this third embodiment, as shown in Figure 5, the mechanism has a central axis (3) and the first turning movement (5.1) of each first and second tanks (1, 20) has a maximum turning angle 180 °, the first position of one of the tanks coinciding with the second position of the opposite tank. In this way, when one of them makes the first turning movement (5.1) to discharge, the opposite tank turns at the same time to be in the position where it is going to be filled again, waiting for a new activation of the a new first turning movement (5.1) for unloading.
    [0148] This mechanism has means for controlling the first position of the first and second tanks (1, 20) similar to those of the first embodiment.
    [0150] As shown in Figure 5, in this third preferred embodiment of the invention, both first and second tanks (1, 20) have means for activating the first turning movement (5.1) arranged on the side surface (1.2, 20.2 ), in the part located frontally in the respective first turning movement (5.1) of each tank, such that they are located asymmetrically. In this second embodiment, these means are formed by a bulge (17) located in the area closest to the opening (4) of each of the tanks. This bulge (17) will collaborate in the beginning of the first turning movement (5.1) at the moment when the first push-button (8) is activated and the first tab (6) is removed.
    [0152] In a fourth preferred embodiment of the invention, a mechanism like that of the third embodiment is considered, but in which the possibility of a partial and complete discharge is also considered, according to the needs of the moment.
    [0154] For this, as shown in Figure 6, the mechanism comprises a second discharge module with the same tanks as the first discharge module, that is, in this case a first and second additional tanks (24, 25) equal to the first and second tanks (1, 20), arranged in parallel thereto and with the same position control means, which have a second tab (26).
    [0156] Thus, the first pushbutton (8) is connected to both the first tab (6) and the second tab (26) corresponding to each pair of tanks respectively, so that first, the first pushbutton (8) has a first pulsation of intermediate discharge and the mechanism comprises a device for activating the first tab (6) of the first and second tanks (1, 20), associated with the first pulsation.
    [0158] Therefore, when this first intermediate discharge pulsation is performed, the withdrawal of the first tab (6) is activated and therefore the discharge of the first or second reservoir is carried out, depending on which is located above both.
    [0160] Second, the first button (8) has a second full discharge pulsation, and the mechanism comprises a device for activating the second tab (26) of the first and second additional reservoirs (24, 25), associated with the second pulsation. .
    [0161] With this, when the second press is made, it is one of the additional tanks that is discharged, the first or the second, depending on which is located at that moment in the upper part and, with this, a complete discharge of the volume is obtained. .
    [0163] In this way, it is possible to regulate the amount of water that you want to discharge, depending on the remains that exist in the toilet and must be dragged.
    [0165] In this case, as each tank is going to discharge a partial part of the total volume, the dimensions of these tanks are smaller than those of the third embodiment of the invention.
    [0167] In other embodiments, to obtain this same control of the discharge volume, the mechanism can comprise additional first and second tanks (24, 25) equal to the first and second tanks (1, 20), arranged in parallel to them and with the same position control means that have a second tab (26), as in the previous case, but unlike the same, here it would have a second button.
    [0169] In this way, the first button (8) is connected to the first tab (6) corresponding to the first and second tanks (1, 20) and, the second button is connected to the second tab (26) of the first and second additional tanks (24, 25), with which, if the user wants a partial discharge, he activates the first button (8) to discharge the first or second tank and, if he wants a complete discharge, he activates the second button, to discharge the first or second tank. additional second deposit.
    [0171] In a fifth preferred embodiment of the invention, such as that shown in Figure 7, the discharge mechanism has a first discharge module comprising first and second tanks (1, 20) of semi-cylindrical shape joined together by the flat face, with the axis (3) located in the center thereof, where both first and second deposits (1, 20) present in the area of the lateral surface (1.2, 20.2) farthest from said flat face, a truncation parallel to it, which forms the opening (4) of each one of them.
    [0173] In this fifth embodiment, both first and second tanks (1, 20) have, as in the third and fourth embodiment, means for activating the first turning movement (5.1), which in this case are formed by a tank auxiliary (13) instead of the bulge (17) and is arranged in the same place, that is, on the surface lateral (1.2, 20.2), in the part located frontally in said respective first turning movement (5.1) of each tank, such that they are located asymmetrically and, specifically, in the part closest to the opening (4) of each deposit. This same effect of shifting the center of gravity of the loaded tank towards the side of the first turning movement (5.1) can be achieved by arranging empty tanks inside the opposite side of that tank, without affecting its external shape. The water inlet (14) is controlled by a buoy (15), placed in each of the tanks.
    [0175] In other embodiments, these auxiliary tanks can be closed tanks with a quantity of water contained therein, arranged inside the first and second tanks (1,2).
    [0177] In turn, a sixth preferred embodiment of the invention is proposed, which can be seen in Figure 8, in which the discharge mechanism comprises a first discharge module with first and second tanks (1, 20) in the form rounded with an opening (4) in a part thereof and a section opposite said opening (4), where both first and second tanks (1, 20) are joined by said section opposite the opening (4) and the shaft (3) is located in the center of said joint.
    [0179] As in the fourth and fifth embodiments, the mechanism only presents a first turning movement (5.1), of an angle equal to 180 °.
    [0181] In this sixth embodiment, both first and second tanks (1, 20) also have means for activating the first turning movement (5.1), formed in this case by an asymmetric widening (19) in the part of the lateral surface ( 1.2, 20.2) located frontally in the respective first turning movement (5.1) of each tank, such that said widenings (19) are arranged asymmetrically and, in the area furthest from the opening (4).
    [0183] This widening (19) makes it possible to ensure the start of the first turning movement (5.1) when the first tab (6) is removed by activating the first push-button (8).
    [0185] In both the third, fourth, fifth or sixth proposed embodiments, in which, as defined, the mechanism has means for activating the first turning movement (5.1), these can vary indistinctly and be formed by a bulge (17 ), or a widening (19), or an auxiliary tank (13), or other similar element that generates an imbalance of forces to activate said first turning movement (5.1).
    [0187] According to another aspect, as shown in Figures 5, 6 and 7, both in the third, as well as in the fourth and fifth proposed embodiments, the first discharge module comprises a buoy (15) associated with each first and second tanks (1, 20) and each of the buoys (15) is connected to a longitudinal sliding element (18) connected to the corresponding tank, so that in the first position of each tank, the associated longitudinal sliding element (18) it is located in connection with the water inlet valve (16).
    [0189] In other embodiments, such as the sixth proposed mode, as can be seen in Figure 8, the buoy (15) is subject to a longitudinal element (23) connected with the water inlet valve (16) and the means fastening the same to said longitudinal element (23) are formed by a tilting shaft (21), where each tank has a thrust stop (22) of the buoy (15) at the end of the opening (4) located in the rear side surface (1.2, 20.2) in the direction of the first turning movement (5.1). In this case therefore, a single buoy (15) acts on both the first and second tanks (1, 20 ).
    [0191] A seventh embodiment is also proposed in which the discharge mechanism comprises a first discharge module, with first and second tanks (1, 20) curved, equal and complementary, joined by a curved contour thereof, as shown in Figure 9, such that they form a cylindrical shape with the two bases (1.1, 20.1) in a vertical position and an outer lateral surface (1.2, 20.2) that presents two opposite openings (4), each corresponding to one of the tanks, the axis (3) of rotation is located in the center of the curved contour of union of said first and second tanks (1, 20).
    [0193] In this case, each tank has a configuration that is wider in the area close to its opening (4) and narrower in the area close to the opening (4) of the opposite tank. This shape itself already acts as an activator of the first turning movement (5.1) when the first tab (6) is removed with the activation of the first push-button (8).
    [0195] In this seventh embodiment, the mechanism comprises a buoy (15) associated with each tank as in the third, fourth and fifth proposed modes, although in the same way that in the rest of the cases except the first one, it could be formed by a buoy (15) connected by a tilting shaft (21).
    [0197] Likewise, in this seventh embodiment, the first and second tanks (1) of this first discharge module comprise means for activating the return to the first position formed by at least some auxiliary open tanks (13) arranged on the surface side (1.2) of both tanks (1), with the water inlet (14) and said auxiliary tank (13) vertically aligned at least in a moment of the second turning movement (5.2) of the first tank (1). In this case, these activation means are useful in the situation in which the push-button is actuated before the tank is full and the tank is semi-rotated, to reposition it in its first position retained by the tab (6) and proceed to its full charge.
    [0199] In this case, as has been seen in other embodiments, to achieve the function of two discharge volumes, one partial and the other complete, depending on the nature and amount of waste to be eliminated, two independent tank modules can be arranged in parallel. , each one with its filling valves, its buoys and its own tabs and pushbuttons, although operable independently or simultaneously or successively, as described in the fourth embodiment. This system to be able to administer different discharge volumes through tanks in parallel can be applied in the other embodiments.
    [0201] In turn, an eighth preferred embodiment of the invention is proposed in which, as shown in Figure 10, the first tank (1) has a cylindrical shape, with two bases (1.1) arranged vertically and a lateral surface ( 1.2) between the two.
    [0203] In this case, the shaft (3) is arranged at an intermediate height of the first tank (1) and eccentrically with respect to its center of gravity in a fully loaded position. Likewise, the first tank (1) has a maximum angle of rotation determined in the second position, less than or equal to 180 °.
    [0205] In addition, in this eighth embodiment, the mechanism has a second turning movement (5.2) in the opposite direction to the first turning movement (5.1), to return the first tank (1) to the first position and the tank has a possibility partial discharge and full discharge.
    [0206] The position control means are the same as those of the first embodiment, and presents the option of partial discharge and complete discharge, so that when the first tab (7) is released and the first turning movement is started (5.1 ), after a push in which the first tab (6) is withdrawn, the reservoir (1) rotates until the additional flange (27) meets said first tab (6). If a second or continuous pulsation is carried out, this first tab is withdrawn again, leaving the additional flange (27) to pass, thereby completely flushing the water.
    [0208] The means for activating the return to the first position, as shown in Figure 10, are formed by a series of auxiliary tanks (13), which in this case are arranged outside the tank, as recesses on the surface outside of it. In other cases they may be internal, or use other means of activation or a combination of them.
    [0210] Thus, when the first tank (1) reaches the second maximum discharge position, the water inlet begins to fill the auxiliary tank (13) arranged aligned with said water inlet and this filling starts the second movement of turn (5.2). As this movement is carried out, different auxiliary tanks are aligned with the water inlet, thus favoring the continuation of this second turning movement (5.2).
    [0212] On the other hand, it comprises a buoy (15) associated with the first tank (1) and connected to a longitudinal sliding element (18), so that in the first position of the tank, the longitudinal element (18) is located in connection with the water inlet valve (16). This longitudinal sliding element (18) has a retraction spring (15.1) that will retract it so that it does not rub against the walls of the tank (2) when rotating the tank and lowering the buoy when discharging into water. The force of this spring is considerably less than that of the buoyancy of the buoy.
    [0214] The described embodiments are only examples of the present invention, therefore, the specific details, terms and phrases used herein are not to be construed as limiting, but are to be understood only as a basis for the claims and as a representative basis that provides an understandable description as well as sufficient information to the person skilled in the art to apply the present invention.
