Definitions

• the present invention deals with discharge and outflow devices applied improved sanitary toilets, more particularly related to a discharge fixture developed as obstruction element for the opening and closing of the outflow pit of the sanitary toilet, particularly those which do not have a siphon;
• a discharge fixture developed as obstruction element for the opening and closing of the outflow pit of the sanitary toilet, particularly those which do not have a siphon;
• such discharge fixture comprises forms and constructions specially designed to allow the adaptation of discharge drives, in addition to an outflow funnel where the discharge equipment are installed, i.e. , a member of articulated floodgate, counterbalance member and drive in the form of a door latch with magnetic or electronic lock, which allow a better adjustment to the operation of the sanitary toilet discharge, allowing them to be cleaned with only 3 liters of water per discharge.
• one of the greatest current problems refers to the relationship between the savings of water and the increase of the population producing human dejections, being inversely proportional, since the higher the number of the people with access possibilities to the use of sanitary toilets with water discharge, the larger is its consumption.
• the sanitary toilet is an anatomic format container equipped with a water pit destined to receiving residues of human physiology and of an internal device capable of removing them by means of a water flow, more usually known as siphon.
• the sanitary toilets used in Brazil may consume up to 12 liters discharge water per cycle.
• the maximum limit of water use by sanitary toilets was changed to 9 liters per discharge and as of 2002, this limit has changed to 6,8 liters, similar level, even higher, to that already adopted by the European Community and North American countries.
• the hydrodynamic energy used in the sanitary toilet cleaning process is provided by a discharge device which feeds the sanitary toilet with water at suitable volume and speed not only to remove the residues deposited therein but also to conduct them through the sewage piping, in the horizontal direction, until they reach the drop pipe of the building installations.
• the sanitary toilets may be currently setup to operate by siphoning or through the dragging system, largely known by the technique.
• both systems operate integrating three basic components, i.e., the sanitary toilet, the discharge box and the sewage, and is processed in three different steps (see figure 1 attached to the drawings): a) The first step, which must consume not more than 40% of the water volume of the reservoir, is destined to break the inertia of the load of liquids and solids deposited in the toilet pit and launch them into the sewage network; b) the second step, consuming another 40% of the discharge water volume, has the purpose of acting as hydrae piston constituted of clean water which maintains the initial flow of the effluents load moving inside the horizontal segment of the sewage piping, until it enters the building drop tube, and c) the remaining 20% of the end of discharge are destined to refill the vase pit and reconstitute the hydrae lock of the system, preventing the entrance of gases and odors to the environment.
• the state of art teaches that the sanitary toilet (1) is generally of the type constituted by a structure of lateral walls from the base (2) over which there lies a container (3) of anatomic form with superior borders (4) and equipped with a water pit (5) destined to receiving the residues of human physiology, which is generally equipped with a siphon or wall in the form of tube (T) and which requires a volume of at least 6,8 liters of water kept in a suitable reservoir (A) for the implementation of the discharge with 80% (a) of the dispensed volume, while 20% (b) of the volume is retained as hydraulic seal.
• the satisfactory performance of a low consumption sanitary toilet depends, therefore, of its capacity of removing the totality of the solid residues with the initial 40% of water discharged by the discharge fixture so that there still remains at least 2,5 liters of clean water to carry the solid residues to the system drop pipe.
• Discharge devices applied to sanitary toilets with outflows having a funnel form are described in patents, such as, for instance, PI 7907568 where a mechanism is associated to a complex driving arm and a blade of the shutter type capable of sealing the edge of the funnel through the pressure exercised by the referred driving arm.
• the European patent EP 1045077 describes a vat used as vase, which funnel is supported over a complex discharge structure, coupled to a discharge box and an arm acting associated to a driving pedal which allows the de-offsetting of the water columns between the hydrae seal, the discharge box and the water outflow to promote the discharge.
• the French patent FR 2618817 refers to a sanitary toilet with discharge by means of the gravitation of the washing water, equipped with an horizontal shutting plate of the inferior edge of the funnel;
• the present discharge and outflow devices were developed to be applied in improved sanitary toilet which allow the perfect and complete operation with maximum 3 liters of water for each discharge and which also provides for the hydrae seal in its constitution.
• One of the improvements introduced comprises the construction of the sanitary toilet, which will now be constituted of a vertical funnel type duct, especially sized and located in the lowest point of the pit formed by the internal walls of the vase container and which is directly connected to the sewage outflow.

• Another innovation related to the building refers to the fact that toilet is equipped with a backside flat extension, equipped with one or two transversal holes, particularly developed for the coupling of a discharge box with two outflows foreseen in the Patent Request no. PI 0203700-0, filed by the same petitioner of the present request.
• Another innovation refers to a funnel type duct especially developed to be easily adapted between the external area of the vase pit and the sewage outflow duct, which funnel is equipped with the vase discharge drives, already described and mentioned in the beginning of the description report as being part of request BR PI 0006521-8 and which comprise the three basic elements, being a shutter in the form of a container sized in accordance to the external area of the vase pit, a counterbalance and a door latch to release the discharge; such basic elements act inside the funnel type duct which, on its side, is responsible for making the connection between the vase pit and the sewage piping, assuring total sealing of the discharge system.
• discharge drives may be made of diversified elements, that is, it may be conformed by mechanical, magnetic or electrical means.
• Figures 1 and 1A are illustrations of the operation of a sanitary toilet operating through dragging and driven by conventional device, where one can observe the water volume required to clean the pit of its container and the quantity of water destined to the preservation of the hydrae seal;
