Description

Discharge and discharge devices applied to An improved hygienic toilet.

Technical field

The present invention relates to devices discharge and discharge applied to toilets or hygienic toilets improved, and, more particularly, refers to a wall lamp of discharge developed as an obstruction element for opening and the closing of the discharge pit of the hygienic toilet, particularly for those without a siphon; said apply of download includes shapes and constructions or structures specially designed to allow device adaptation discharge drive, in addition to a mouth or throat of discharge in which the unloading equipment is installed, that is, a member of articulated discharge gate, a member of counterweight and a drive device in the form of a gate bolt with a magnetic or electronic lock, which allows a better adjustment to the operation of the discharge of the hygienic toilet, so it makes it possible for them to be cleaned with so Only 3 liters of water per discharge.

Fundamentals of the technique

As is well known, one of the greatest current problems refers to the relationship between saving of water and the increase of the population that produces depositions human, which are inversely proportional, since how much greater is the number of people who have the possibility of accessing the use of hygienic toilets with discharge water, the greater the consumption of it.

As currently designed, the toilet or toilet is an anatomically shaped container that It is equipped with a water well to receive waste physiological human, as well as with an internal device capable of remove them by means of a water flow, more commonly known as a siphon

The old hygienic toilets required large volumes of discharge water, which made them responsible of high water consumption in homes.

In 1997, as had been done in the countries of first world with the purpose of reducing water consumption in hygienic facilities, the Ministry of Interior, through Brazilian Program of Quality and Productivity in the Home ("Brasileiro da Qualidade e Produtividade Program no Habitat ") -PBQP-H [" Brazilian Program of Quality and Productivity at Home "-PBQP-H], established in a standard, in close cooperation with manufacturers of the sector, new maximum limits for the use of water for cleaning of hygienic toilets, in order to be adopted gradually until 2002.

In accordance with said government order, until 1999 the hygienic toilets used in Brazil they could consume up to 12 liters of discharge water in each cycle. As for the year 2002, the maximum limit of water use by Hygienic toilets were changed to 9 liters per discharge, and so compared to 2002, this limit has been changed to 6.8 liters, a level similar, and even superior, to that already adopted by the Community European and North American countries.

In order to establish and control the volume of water consumption of hygienic toilets, it is necessary that the discharge is equipped with a discharge box that, due to to its own nature, it can only release volumes of water from according to the volume of the tank, since the volume of water released by the wall valves depends on the magnitude of the time the button is held down.

The hydrodynamic energy used in the Sanitary toilet cleaning process is provided by a discharge device, which feeds the hygienic toilet with water in a suitable volume and speed, not only for remove waste deposited inside but also to lead them through sewage pipes in horizontal direction, until they reach the drop pipe or downspout of building facilities.

Hygienic toilets can be disposed in the actuality so that they work by siphon effect or through of the drag system, widely known in the art.

For illustration only, both systems (siphon and drag effect) work by integrating three components basic, namely the toilet, the discharge box and the wastewater, and its procedure is carried out in three stages different (see Figure 1 accompanying the drawings): a) The first stage, which should not consume more than 40% of the volume of water from the tank, is destined to break the inertia of the load of liquids and solids deposited in the toilet well, and push them into the sewage network; b) the second stage, which consumes another 40% of the water volume of discharge, is intended to act as a hydraulic piston constituted by clean water, which maintains the initial flow of the effluent load that travels inside the segment or horizontal section of sewage pipes, until it enters the downpipe of the building, and c) the remaining 20% of the  end or end of the discharge is intended to refill the vessel or well receptacle and reconstitute the lock or hydraulic plug of the system, thereby preventing the entry of gases and odors into the environment.

Following the drawing in Figure 1, the state of the art advocates that the hygienic toilet (1) is, generally, of the type constituted by a wall structure laterals that emerge from a base (2), on which rests a anatomically shaped container (3), provided with upper contours (4) and equipped with a water well (5) intended to receive residues of human physiology, which is equipped usually with a siphon or wall in the shape of a tube (T) and which requires a volume of at least 6.8 liters of water, maintained in a suitable tank (A), to carry out the discharge with the 80% (a) of the volume dispensed, while 20% (b) of the volume is retained as hydraulic or water seal.

The satisfactory behavior of a toilet Low consumption hygienic depends, accordingly, on your ability to eliminate all solid waste with the Initial 40% of the water discharged by the discharge wall, of such so that there are still at least 2.5 liters of clean water to transfer solid waste to the downstream pipe system.

Download devices applied in hygienic toilets and having ducts with the shape of a throat or funnel are described in Patents such as, by example, document BR 7907568, in which there is a mechanism associated with a complex drive arm and a shovel of the type shutter gate, able to seal the edge of a funnel by means of the pressure exerted by the drive arm referred.

European Patent EP 1045077 describes a tank which is used as a vessel or receptacle and whose funnel is supported above a complex download structure, coupled to a discharge box and an arm acting on association with a drive pedal that allows you to undo the counterbalanced water columns between the plug or plug hydraulic, the discharge box and the discharge pipe, in order to cause the download

French patent FR 2618817 refers to a hygienic toilet with a discharge through the effect of gravity in the wash water, which is provided with a plate shutter on the bottom edge of the funnel.

As can be seen in the documents previously described, despite the fact that the document French shows more clearly the concern for saving water, does not have the same consideration, as in the rest documents, as regards the hydraulic seal, this element which is unquestionably necessary to prevent the flow of recoil of foul gases that come from the waters residual

Another important aspect is that the documents referrals establish that the shutter gate returns to the resting position through complex mechanisms, which, In addition to increasing the cost of the system, it depends on the perform maintenance at given time intervals.

This Petitioner already has a Request of Patent filed in the INPI with the number BR 0006521-8, on 12/09/2000, which revindicated a discharge device equipped with a discharge gate laminate, following the same concept as those described by Foreign patents, although, however, very inventive, since the operation is different from those referred to above and shows innovative drive means, by blocking and return to the initial position of a door latch, using the Use of a counterweight. However, with the developments and trials Practical, the Petitioner has developed said download, conduit of pouring and constructive device, giving rise to the present Request for improvements introduced in the device discharge.

Brief Description of the Invention

As a result of everything described previously, the present devices of discharge and discharge in order to be applied in a hygienic toilet improved, allowing a perfect and complete operation with a maximum of 3 liters of water per discharge, and that also provide, in its construction, the hydraulic seal or by water.

One of the improvements introduced includes the construction or structure of the hygienic toilet, which will be now constituted by a duct of the vertical funnel type, dimensioned and located particularly at the lowest point of the well formed by the inner walls of the container receptacle, and that is directly connected to the conduit of wastewater discharge. The size and shape of the funnel of receptacle, referred to as hereafter, constitute one of the fundamental objects of the present invention, because the other devices are closely related to said building.

Another innovation related to construction is refers to the fact that the toilet is equipped with a flat extension of rear face, equipped with one or two transverse holes, particularly developed for the coupling of a discharge box with two discharge pipes which are already anticipated in Patent Application N ° PI 0203700-0, filed by the same Petitioner of This application.

Another innovation concerns a type duct funnel that has been specially developed to fit easily between the outer surface of the receptacle pit and the wastewater discharge duct, such that said funnel is equipped with the drive devices of discharge of the receptacle, already described and mentioned at the beginning of Descriptive Report as part of the BR PI Application 0006521-8, and comprising the three elements basics, which are a gate in the shape of a container sized according to the external area of the well of receptacle, a counterweight and a gate bolt, intended for trigger the download; these basic elements act in the inside the funnel type duct, which, outside, is responsible for making the connection between the receptacle well and sewage pipes, ensuring total sealing of the download system.

Another object of the present invention lies in the fact that the discharge drive devices they can be made of various elements, that is, they can be formed by mechanical, magnetic or electric

In view of the proposed objects, the main of them is the fact that the drive can come of a discharge box that supplies only 3 liters of water, which results in many greater savings when the device innovation is compared to any other type of model conventional discharge device.

Brief Description of the Invention

Referring to the drawings that are illustrate, the present invention relates to "Devices of discharge and discharge applied to an improved hygienic toilet ", and  in it the hygienic toilet (1) (Figures 2, 3 and 4) is of the type constituted by a structure of side walls that emerge from the base (2), on which a container (3) rests so anatomical, provided with upper contours (4) and equipped with a water well (5) intended to receive physiology waste human, which is usually equipped with a siphon or wall with the shape of a tube (T) (see Figures 1 and 1A) and that requires a volume of at least 6.8 liters of water, maintained in a adequate deposit (A), to carry out the discharge with 80% (a) of the volume dispensed, while 20% (b) of the volume is retained as hydraulic or water seal.

In accordance with the present invention, the vessel or receptacle construction (Figures 2, 3 and 4) associated with the remaining devices and the download of innovation, It allows the cleaning of the toilet (1) to be carried out with a maximum of 3 liters of water per discharge cycle, 15% of the water already included intended to produce the hydraulic seal, and for this, the water well (5) is composed of a funnel type duct (6), of elliptical section, which extends or protrudes towards the exterior, offset and with a vertical shape in relation to the vertex of the bottom of the well (5); so that the height (x) of funnel type duct (6) corresponds to practically ½ of the height (y) of the structural walls of the base (2) of the receptacle.

On the underside of the duct type funnel (6) devices (D) are attached responsible for the discharge drive, and it effect the release, closure and hydraulic sealing (see figures 7, 7A, 8, 8A, for example).

The upper face of the toilet is equipped with a flat extension of the rear face (7), equipped with one or two transverse and hollow or hollow holes (8), particularly developed for the coupling of a box of discharge (which controls the opening and closing of the tank (A), no shown in the figures), capable of contemplating the adaptation of a conventional discharge duct or two discharge ducts with Different volumes and flow controls.

Around the funnel type duct (6) of the hygienic toilet the device (D), compounds have been installed by a funnel (10), preferably made of ceramic material (Figures 5 and others), which is equipped with the devices of actuation of the discharge of the receptacle, which comprise three basic elements, among which is a gate shutter in the shape of a container (11), a counterweight (12) and a gate bolt (13), provided with a device for magnetic lock drive (15) (14) or electric / electronic

Said funnel (10) has been sized especially so that it has the upper contour (10a) properly installed on the outer face of the duct type funnel (6) of the receptacle, while the end contour bottom (10b) is coupled to the discharge pipe (E) of the system sewage water; the funnel type duct (10) is the responsible for establishing the connection between the well (5) of the receptacle and sewage pipe (E), thereby ensures the total shutter of the discharge system.

\hbox{eléctrico/electrónico}.

The shutter gate (11) of the funnel (10) of the receptacle makes it possible that, on one of its external faces, a rod end (16) is fixed, the other edge of which is fixed to the counterweight (12), whose free face has means for blocking an protruding member (17), such that said blocking means comprise the characteristic of blocking or releasing the gate bolt (13), said release being provided by the conventional external control drive device, associated with the discharge of water from the coupled box, or by other means of actuation, as long as
that the blocking is done through the drive device (15) of the magnetic type (14),

 \ hbox {electric / electronic}. 

The shutter gate (11) and the counterweight corresponding (12) can be pivoted with respect to the funnel (6) by means of the articulation element (AT), provided in a suitable place of the funnel type duct (6), such that said shutter gate and said counterweight are maintained in resting position with a given volume of water (AG), so guarantees water sealing according to the physical principle of the communicating vessels.

One of the solutions for driving the discharge works by magnetic means (14) (Figures 5 and 5A), and in it the protruding element of the counterweight (12) comprises a magnet (M1), while the gate bolt (13) is constituted by a supplementary magnet (M2), supported on a outgoing (13b) travel limiter, capable of maintaining the shutter gate (11) and the corresponding volume of water (AG) in rest position until the water discharge is sufficient to overcome the strength of the magnet, causing the tilt of the shutter gate and releasing water and bowel movements; he counterweight is responsible for returning the shutter gate to its resting position, which remains that way thanks to the strength of The magnets.

According to Figure 8 and 10, just as schematic example, the magnet elements (M1) and (M2) can be displaced to another position, such as, for example, fixing of the magnet (M1) on the inside of the funnel type duct (10), and fixing the magnet (M2) in the upper contour of the shutter gate (11), so that the magnetic field balance for the resting position of the shutter gate (11), until the volume of water is released that arrives from the discharge box; the counterweight (12) is maintained in the articulated position, with a view to exercising its drive feature to open and close the gate shutter

One form of drive (Figures 6 and 6A) is performs by electrical or electronic means (15), which they consist, in a preferred solution, in means (15) such that they comprise a pin (18) and a solenoid (18a, 18c) that act on the gate bolt (13), releasing or blocking the counterweight (11).

The funnel type duct, particularly its upper opening, can contemplate the fact that its contour upper peripheral (10a) is equipped with a flange (19) that protrudes in order to prevent some of the water that rests as hydraulic shutter is thrown outside with the discharge of receptacle; said flange (19) has been developed so that subject to continuous washing with discharge.

The improved device, as stated above, it can be preferably made of material sanitary ceramic, although, however, alternatively, it can be made of stainless steel or even of a given type of plastic that has molecular characteristics resistant to natural effects of water and other depositions, and that is capable of presenting shapes such as the one illustrated in Figure 10, while retaining the characteristics of being composed by a funnel type duct (10), with the elements interrelated constituted by a shutter gate with container shape (11), a counterweight (12), a bolt of gate (13), so that said elements act in the inside the funnel duct (10), which, in turn, has an upper contour (10a), provided with a sealing flange peripheral (19), and a lower contour (10b), capable of being coupled to the discharge pipe (E).

Figure 9 shows the download device applied (10) to a hygienic toilet (1) that pours into a vertical and ground pipe (E), while Figure 10 shows the device (10) applied to a sanitary toilet with Drag discharge, illustrating the preferred arrangement of the funnel type duct, with its water discharge duct (E) residuals directed towards the back wall.
