Abstract

The present invention relates to an articulated siphon, installed at the base of the toilet bowl, which moves when the toilet is flushed. The movement of the water from the flush presses the articulated siphon downward, allowing full use of the combined volume of water contained in the articulated siphon and in the base of the bowl in order to discharge waste into the sewage system.

Description

ARTICULATED SIPHON FOR TOILETS

[001] The present invention is an articulated siphon, installed at the base of the toilet bowl, which moves when the toilet is flushed. The movement of the water from the discharge presses the articulated siphon in a downward movement, allowing the total use of the volume of water contained in the articulated siphon and in the base of the basin, in a single dose, allowing the disposal of waste to the sanitary sewer.

Fundamentals of the Invention

[002] The siphon is an essential product in the installation of sinks, tanks, washbasins and vats. Its purpose is to keep environments free of odors from sewer pipes.

[003] A fully effective flush, especially when the toilet is full of waste, toilet paper and other solid materials can be difficult, especially for toilets with low water volume.

[004] It is very common, especially in toilets with a low volume of flush water, that it is necessary to apply several flushes to clean the entire vessel satisfactorily. Not only is this frustrating and time-consuming, but it also has the potential to clog the toilet, making the task more complicated. There is also the issue of environmental and conservation efforts in many places that regulate water consumption, which in many areas cannot exceed 6.1 liters of water per flush.

[005] Conventional toilets have a basin and a storage box for flushing water, usually made in one or two main parts. An “S”-shaped passage, normally defined as a siphon, is positioned behind and below the basin to connect the contents of the basin to the waste piping of the buildings. The siphon of a vase The toilet has the function of retaining the sewer gases, in order to prevent them from entering the interior of the bathroom. The siphon also holds the water in the bowl before flushing.

[006] During the discharge cycle, water and waste within the basin are directed to the siphon, passing through the “S” curves through an outlet to the sewer piping lines. This point is invariably a bottleneck for the passage of waste.

State of the art

[007] The patent application CN1718956A reveals a toilet whose discharge is equipped with a flexible hose, in the shape of "S". The siphon effect of the toilet can be increased through the size of the hose, and in addition, the effects can be achieved that the drain hose cannot be blocked and the flush water can be saved. The siphon's flexible hose is inserted directly outside the sewer outlet pipe.

[008] The invention CN203546853U deals with a toilet with siphon composed of the following components: discharge mechanism, toilet seat, water sealing tube and toilet lid. The flushing mechanism is arranged on the toilet seat. A water discharge opening in the flush mechanism communicates with a discharge channel through the toilet seat. A discharge opening from the seat of the toilet is communicated with the sewer discharge piping. According to the toilet, the siphon, the magnet and the iron block are combined with each other and arranged between the toilet seat and lid.

[009] The invention EP2309065A1 discloses a toilet with water discharge flow to release the contents of the vessel and to clean the surface of the vessel. During a washing operation, the water nozzles, in an internal arrangement in the toilet basin, are used to clean the surface of the basin in a region of transition to a siphon. The water jets are directed specifically to the transition region of the siphon, causing turbulence, facilitating the exit of waste.

[0010] The patent application JP2011174303A discloses a drain connector capable of properly discharging wastewater from a toilet body. The drain connector connects an outlet of a toilet drain channel that is coupled to one side of the toilet water outlet provided in a toilet body and an inlet port of a drain pipe that opens to the drain pipe. bathroom where the main body of the toilet is installed.

[0011] The patent application JP2011174303A describes a drain connector, a flush toilet and a construction method and an accessory for the flush toilet, which can save installation work of the flush toilet.

[0012] The invention PI0103861A enables the operation of flushing excreted material into a toilet using wastewater or mains water, in both cases consuming only 1 to 2 liters of water per flush, thus providing lower water consumption drinking water and electricity in high-rise buildings. This toilet, based on the principle of a flexible siphon, is activated manually through a lateral cable in the defecation position, allowing the discharge of waste by gravity, dispensing with the high volume of water required for this operation in the traditional fixed siphon system.

[0013] Patent PI0705136-0 A2 describes a toilet consisting of a basin, with a siphon integrated into an actuation set and a cleaning system; in the lower portion of the basin there is a nozzle, in which one of the ends of the siphon is coupled, the opposite end being connected to the sewer pipe; the siphon is flexible and can be lifted by the drive assembly, which prevents the passage of gases from the sewer pipe; the drive assembly is arranged at the bottom of the vessel and comprises a lower lever, spring, rod, upper lever and bearings; the lower lever has a pedal facing the anterior end of the vessel, which can be operated with the feet; the opposite end of the lower lever is mechanically connected to the rod which in turn is joined to the upper lever which can rotate by means of bearings, the upper lever supporting the siphon; the cleaning system consists of a flow control valve, piping and water spray nozzles; the pipe has a branch that crosses the basin, at the height of the nozzle, and whose purpose is to generate a jet of water that helps to clean the basin; the piping extends and surrounds the upper internal portion of the basin, and in this region it has multiple nozzles that direct the water to clean the basin.

[0014] The documents presented as prior art reveal devices configured in siphons for coupling in toilets. In the state of the art, toilets are provided with a discharge channel below the toilet and a curved end of the drain in an “S” shape. They are connected to the toilet and at the other end to the sewer outlet. The recurring problems of state-of-the-art siphons are poor drainage and high consumption of water from toilet bowls. Generally made with rigid material and in some cases, with flexible material for ease of adaptation to the sewer pipe, however, none of them allows movement like a bellows during discharge. [0015] Therefore, there is a need for an articulated siphon for toilets, and that have better siphoning effects that allow greater water savings and do not block the sewer pipe. According to NBR 15097-2004, item 3.5 - The siphonic action is the operating process of the sanitary basin that makes use of the speed and the total or partial filling of the discharge channel by the water supplied by the discharge device, creating a suction effect in the well, removing the waste deposited in it.

[0016] The present invention proposes an articulated siphon with three main parts that are joined together forming an articulated siphon to be installed in toilets. The connections are joined between the water outlet of the toilet bowl and the entrance to the sewer pipe (4) and is characterized by comprising 2 flexible parts (1) and (3) and a rigid intermediate part in the shape of an elbow (2) .

[0017] The advantages of the invention will be evidenced from the detailed description of the drawings:

Detailed Description of the Invention

[0018] The present invention comprises parts that are joined together forming an articulated siphon to be installed in toilets. As shown in the drawings, the articulated siphon comprises 2 flexible parts (1) and (3) that can be in material: silicone, PVC, nitrile rubber, epdm rubber, latex, polyurethane or other polymers with elasticity characteristics and a rigid elbow (2) composed of metallic or polymeric material.

[0019] The flexible part (1) of the articulated siphon has a diameter between 60 and 80 mm and a length between 30 and 60 mm and is connected to the base of the sanitary basin and the other end is connected to the rigid elbow (2). The rigid elbow (2) has a diameter between 60 and 80 mm and a length between 250 and 420 mm. At the other end of the rigid elbow (2) it connects to the other flexible part (3) of the articulated siphon with diameter 0 between 60 and 80 mm and length between 180 and 300 mm and at the other end the flexible part (3) has diameter 01 between 80 and 100 mm to be connected to the sewer pipe (4). At the ends of the flexible parts of the articulated siphon, internal transverse microgrooves are arranged in the form of rings for better fixation and sealing of the part with the toilet, the plumbing and the rigid elbow. For a better fixation of the flexible parts that make up the articulated siphon, gloves or metallic straps must be used with the rigid parts (5). Thus, the articulated siphon is attached to the base of the sanitary basin through a glove or metal strap and next to the sewer pipe by a sealing ring (6), which is subjected to a tightening within the concept of clamps.

Functioning description

[0020] While the discharge is not activated, the articulated siphon is in the original position (Fig. 2). When the discharge is activated, the water from the vessel and the column are directed to the siphon. Due to the water discharge pressure, the flexible piece (1 ) that connects the toilet outlet to the elbow (2) and the flexible piece (3) that connects the elbow (2) to the sewage pipe (4) are compressed in a vertical and downward motion. Due to the compression of the two flexible parts, the siphon is articulated and this articulation makes the repression possible. at high speed and intensity the water from the vessel and from the discharge water column.

[0021] The main differential of the invention refers to the articulation of the siphon and its internal dimensioning, which makes it less susceptible to clogging. Unlike conventional toilets where the siphon is fixed and rigid, the articulated siphon object of the invention has two flexible parts that compress, that is, "shrink" vertically and downwards in a bellows movement (Fig. 3) impelling the entire the waste at the time of discharge. This means that, when flushing, the water flow moves the flexible parts (1 ) and (3) compressing them, and this compression presses the water volume intensely and quickly, facilitating the passage of waste and discarding all contents. for sewer plumbing.

[0022] After disposing of the volume of water with the waste, the articulated siphon returns to its original position (Fig. 2), that is, the flexible parts return to their original state.

[0023] The water consumption of this invention is optimized by the fact that there is no need for an external discharge volume to promote the repression action. The set is unprecedented, has a low manufacturing cost and contributes to the improvement of basic sanitation and significantly to the sustainability of water resources.
