DESCRIPTION

Loading and unloading device for toilets. The present invention relates to a loading and unloading device for toilets, which makes it possible to decide between total or partial discharge of water inside the toilet tank. Background of the invention Traditionally the toilets had a discharge device with which all the water 10 present in the toilet tank is discharged. In practice it was shown that it was not always necessary to discharge all the water in the tank to clean the toilet bowl, and for ecological reasons different discharge devices were designed that would allow the user to select a reduced discharge or a total discharge of water in the the inside of the toilet tank.  fifteen Two download devices of the same holder of the present application are described in utility models U9701307 and U200501525. These discharge devices comprise two push-buttons, one for total discharge and the other for reduced discharge, which actuate a movable body provided with articulated floats located inside a superiorly open container.  twenty These devices work correctly to allow the total or partial discharge of water into the toilet tank, but they have a number of limitations. First, the distribution of the floats and their design limit the height, the discharge configurations and the residual levels of the device. In addition, the position of the concentric floats with the axis through which they move limits the travel of the floats along the axis, allowing fewer discharge configurations. The design of the floats also limits the range of the 25 discharge configurations and the increase in residual levels after the discharges. Another limiting factor in its operation and design is the internal overflow of these devices. The overflow, as a safety element, must have a minimum flow of water suction to avoid flooding in the bathroom, and due to its design, the minimum flow is within the limit established by current regulations 30, since the location of the overflow It limits the design of other components such as the push button and floats. In addition, the internal overflow has a height limit that does not allow the water level to rise and to design narrow and tall cisterns. Another drawback of the current devices is the design of the lower windows through which the water flows, which limits the discharge flow, making it close to the minimum established by current regulations. On the other hand, the installation and disassembly of current discharge devices are impractical and very complex, making maintenance difficult. During assembly and disassembly there is a risk of wasting or breaking parts due to the fit and pressure system used. 40 Regarding the load, in today's devices it is usual to use a large float to ensure sufficient force to quickly close the water inlet. The float is sheathed so that the reaction time to close the water inlet is minimal. The voluminous dimensions of the float condition the design and the path of the discharge device. Four. Five The assembly of the loading device and the discharge device, which must be housed inside the toilet tank, also present a limitation for the design of new toilet models. The ergonomics of the toilet tank must adapt to the mechanisms preventing total freedom to make different designs, since their proper functioning must have certain dimensions and space. fifty Therefore, it is an objective of the present to provide a loading and unloading device for toilets, which is more versatile and can be adapted to any space. In addition, another objective is that the device of the present invention be more comfortable for the user, from the point of view of operation and noise, and that it can also meet the highest quality requirements of the different international regulations. 55 Description of the invention With the toilet loading and unloading device of the invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described. 60 The toilet loading and unloading device of the present invention comprises: - a pair of push-buttons, one for the total discharge of the water contained in the toilet tank and the other for the reduced discharge; 65 - a movable central axis linked with said push buttons; - a reduced discharge float and a total discharge float linked to said movable central axis; Y - a solidarity discharge valve with said movable central axis, which opens and closes the outlet opening of the toilet; characterized in that it also comprises a load float associated with a load valve, and by the fact that said load float, said reduced discharge float and said total discharge float are arranged inside a housing. 10 Advantageously, said central axis comprises hooking means for engaging the total discharge float when the total discharge button is pressed, and hooking means for engaging the reduced discharge float when the total discharge button or the push button is pressed. reduced discharge  fifteen According to a preferred embodiment, said engagement means are recesses located in said central axis complementary with a projection of the total discharge float and with a lever integral with the reduced discharge float. Preferably, said total discharge float is tilting around a rotation axis located in its lower part 20. Advantageously, said load float is height adjustable to regulate the maximum water load level inside the toilet tank, and said partial discharge float is height adjustable to regulate the reduced discharge water level. 25 According to a preferred embodiment, said reduced discharge float is associated with a guide provided with a projection capable of coming into contact with the lever of the reduced discharge float when said float loses its buoyancy force and falls by its own weight, so that said lever is removed from the respective inlet of the central axis and disengagement of said discharge float occurs. 30 Said housing advantageously comprises in its lower part a plurality of holes that can be selectively opened or closed to regulate the delay and the residual level of the total discharge. In addition, said holes can be selectively opened or closed by a movable plate. 35 According to a preferred embodiment, said inlet valve comprises an actuator linked to said load float, which drives the opening and closing of said valve. Said inlet valve preferably comprises a joint that opens and closes the passage of water between an inlet 40 and an outlet. The following advantages are achieved with the loading and unloading device of the present invention: - the design of the base of the device of the invention is optimized to increase the discharge rate. Four. Five - Floats are optimized to obtain a maximum range of discharge volumes; - the sensitivity of residual water levels after discharges is increased;  fifty - the flow of the overflow is increased during the discharge; - the interaction between the installer operator and the download device is improved; - it facilitates the assembly and disassembly of the device. 55 Brief description of the figures To better understand how much has been exposed, some drawings are attached in which, schematically and only by way of non-limiting example, a practical case of realization is represented. 60 Figure 1 is an elevational view of the loading and unloading device of the present invention sectioned, in its closed position of loading and unloading; Figure 2 is an elevation view of the sectioned loading and unloading device of the present invention, in its position of opening the total loading and unloading; Figure 3 is an elevation view of the sectioned loading and unloading device of the present invention, in its position of opening the reduced loading and unloading; Figure 4 is an elevational view of the sectioned load valve, in its closed position; 5 Figure 5 is an elevational view of the sectioned load valve, in its opening position; Y Figure 6 is a perspective view of the lower part of the housing of the device of the present invention, in which a plurality of holes can be seen to regulate the delay and the residual level of the total discharge. 10 Description of a preferred embodiment As can be seen in the figures, the loading and unloading device for toilets of the present invention comprises a pair of pushbuttons 1a, 1b, one for the total discharge 1a and another for the reduced discharge 1b, 15 linked through a lever 2 with a movable central axis 3. The loading and unloading device also comprises a float for total discharge 4 and a float for reduced discharge 5. Said floats 4, 5 are housed inside a housing 7, which also houses the central axis 3 and said lever 2 . twenty Said float for the total discharge 4 comprises a rotation axis 6 which joins it to said housing 7, as will be described later. This central axis 3 is vertically movable as will be explained later, and comprises a pair of 25 recesses 8a, 8b, a first recess 8a that acts with the total discharge float 4 by means of a first projection 16 of the total discharge float 4, and a second recess 8b acting with the reduced discharge float 5 by means of a reduced discharge lever 9 integral with said reduced discharge float 5. The position of the reduced discharge float 5 can be adjusted vertically to determine the volume of water 30 that is discharged when the reduced discharge button 1b is pressed. Said regulation is carried out by means of a guide 10 provided with a teeth, so that said reduced discharge float 5 can be placed in the desired position along said teeth. A valve 11 is arranged at the lower end of said central axis 3, which in the position shown in Figure 1 closes the outlet opening 12 of the toilet. The device of the present invention also comprises a water charge valve 13 associated with a load float 14. The position of said load float 14 can be adjusted by means of a threaded rod 15, and the load float 14 is integral with the upper end of said lever 2. Said position of the load float 14 40 will determine when the load valve 13 is opened and closed depending on the level of water inside the toilet tank. As can be seen in the figures, said load float 14 is also located inside the housing 7, like the rest of the floats, achieving a versatile and compact device. The process of complete and partial discharge of the device of the present invention is described below, with reference to Figures 2 and 3, respectively. Figure 2 shows the device of the present in its position of total discharge. From the position represented in figure 1, when a user wishes to perform the total discharge of the water present in the toilet tank, press the total discharge button 1a. By pressing said button 1a, the central axis 3 moves upwards by means of the action of the lever 2. When moving upwards, the central axis 3 engages the reduced discharge float 5, when the reduced discharge lever 9 is held with the upper part of the reduced discharge inlet 8b, and also engages the total discharge float 4, when its projection 16 from the top of the total discharge inlet 8a. In addition, the central axis 3 also displaces the valve 11 and opens the outlet opening 12 of the toilet, discharging the water. As the water inside the toilet tank is discharged, there comes a time when the water reaches a level called reduced discharge, in which the reduced discharge float 5 disengages.  60 The reduced discharge float 5 loses its buoyancy force (force that pushes it up when submerged) and falls by its own weight, so that it disengages because the reduced discharge lever 9 comes into contact with a projection 27 provided in the guide 10, causing said lever 9 to cease to be in contact with the upper part of the reduced discharge inlet 8b, as shown in Figure 2.  65 When the reduced discharge float is disengaged, the central shaft 3 will still have the float attached to it. Total discharge 4, but as the water level inside the toilet tank is reduced, there will come a time that will reach the so-called total discharge level. At this level, the total discharge float 4 will also disengage from the central axis 3, since this float 4, which loses its buoyancy force without the action of water, will rotate around its axis of rotation 6, so that it protrudes 16 will be separated from the inlet 8a, allowing the central axis 3 to fall. In the lowest position of the central axis 3, said valve 11 closes the outlet opening 5 12. In figure 3 the device of the present invention is shown in its reduced discharge position. The main difference with respect to the total discharge is the path of the central axis 3. By pressing the reduced discharge button 1b, the central axis 3 is raised less than when the other button 1a is pressed, so that the total discharge float 4 it is not hooked with the central axis 3, as shown in figure 3. In this way, when the water level in the toilet tank reaches the reduced discharge level, the reduced discharge float 5 will be disengaged from the central axis 3 in the same way as described above, but 15 when the other is not engaged Float 4, there is nothing preventing the lowering of the central axis 3. Thus, the outlet opening 12 is closed beforehand by the valve 11, leaving a predetermined volume inside the toilet tank. Said predetermined volume may be regulated by the position of the reduced discharge float 5 along the guide 10.  twenty In figures 4 and 5 the loading valve 13 is shown, in the closed and open positions, respectively. Said charging valve 13 comprises a water inlet 17, a joint 20 associated with an actuator 19, which determines the opening or closing of the valve 13, a compensation chamber 21 for equalizing the pressures inside the valve 13, a protection device 22 to prevent the opposite flow of water for safety reasons, and a water outlet 18. The operation of the loading valve 13 is as follows: in the closed position, shown in Figure 4, the actuator 19 closes an outlet port to the atmosphere 23. Said actuator 19 is linked to the load float 14 described above, so that when said float 14 is in the maximum filling position of the toilet tank 30, the actuator 19 closes the outlet orifice to the atmosphere 23 preventing the loading of water to the toilet tank. When the water level inside the toilet tank is lower than said maximum filling level, the load float 14 will also be at this level and will move said actuator 19 defining a rotation movement. The actuator 19 will open the outlet orifice to the atmosphere 23 and, due to atmospheric pressure, will place the gasket 20 in its opening or passage position of the water. Next, the water will circulate to the outlet 18, which through a tube 24 will be fed to the bottom of the toilet tank. Although not shown in the figures, it should be noted that the supply to the inlet 17 of the load valve 13 is preferably carried out by a flexible tube, which allows the loading and unloading device to be unique, regardless of the input of water to the toilet In Figure 6 it can be seen that the housing 7 comprises, below the total discharge float 4, a plurality of holes 25 to regulate the delay and the residual level of the total discharge. The holes 25 can be covered by an adjustable plate 26, so that more or less holes 25 can be covered. In a preferred embodiment, said holes 25 are seven, and the residual level of the total discharge can be regulated, for example, between 40 mm and 110 mm, which together with the regulation of the position of the reduced discharge float 5, allows to arrange of a wider range of configurations of water volumes (total and reduced). fifty Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the described loading and unloading device is susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by others technically equivalent, without departing from the scope of protection defined by the appended claims. 55
