Definitions

• the present invention relates to the field of sanitary installations in general and more particularly to water closet.
• the invention relates to an installation using a bowl provided with a conformation allowing rapid and safe operation, under improved hygienic conditions, in particular in terms of cleaning the walls of the bowl and above all saving water consumption.
• the invention can be applied to any container or bowl associated with a water supply in order to ensure cleaning and rinsing, the bowl having to be cleaned and rinsed after each use giving rise to the deposit of materials to be discharged . It is in this context that the concept used in this request for sanitary installations must be understood.
• This water comes from the city's water supply network. It is therefore a water that has been laboriously purified and purified to be made drinkable and which is somewhat wasted on each use; so it is envisaged to provide in urban networks a double supply of water simply clarified for the needs of the household and which would be used in toilet bowls, another network being reserved for potable drinking water and Cooking.
• Another project envisages an internal recycling of the water in each dwelling, the water used for the occasion for example of body washing or washing of linen can be reused precisely for the needs of rinsing of the evacuation in the installations of WC
• the walls of the toilet bowls follow a concave profile starting from the upper edge to reach the constricted bottom from where the pipe, fitted with an isolation siphon, leads to the drainage network.
• the upper edges generally have a return " towards the inside in the form of a tunnel open towards its base and constituting the upper flange for guiding the rinsing water coming from a supply source opening into the interior space of this flange.
• This power source can come directly from the network or from a flush tank, or finally from a source of pressurized water, in particular pneumatic.
• a source of pressurized water in particular pneumatic.
• two dominant systems are known.
• the bowl In a first known system called "siphonic bowl", the bowl operates with a large volume of water, of the order of 12 to 14 liters. These bowls do not require a rapid arrival of water and, in some cases, the distribution of water in the bowl is carried out from the flange which is closed at its base with small openings or evacuation perforations to allow the water flow from the flange along the walls of the bowl. When the water in the bowl has reached a certain volume, the priming action of the siphon occurs and it is the entire contents of the bowl which is then evacuated by the call of the siphon.
• FIG. 1 A traditional direct-flush bowl is shown in Figures 1 and 2.
• the upper flange for guiding the rinsing water is open at its base and the water is injected from its supply mouth towards the interior space of the flange.
• the water animated by a significant kinetic speed, comes to break its jet on the falling wall of the flange so that this water disperses according to divergent nets animated by a regime multidirectional vortex, so as to spread over all the walls of the bowl which must be cleaned.
• bowls have a distributor aimed at directing the water streams inside the bowl, but this is to the detriment of the kinetic energy animating the streams whose speed is reduced, so that their washing efficiency of the walls is reduced, as is slowed down
• the siphon is itself produced from a wall forming a plunging veil from the rear part of the bowl and this wall ending in a sharp edge; this conformation requires a very tight turn in the water course by making
• the present invention aims to remedy these drawbacks and proposes a bowl having a total efficiencycot_ in the phenomenon of rinsing and evacuation of water while using a quantity of water considerably reduced compared to the previous systems.
• the sanitary installation with water effect of the type comprising bowl extended at its base by a
• ** _ o drain pipe with interposition of a siphon, the bowl being supplied with rinsing water and its upper edge having a return from the wall towards the inside forming a distribution flange open towards the bottom, for guiding and distributing the rinsing water coming from a water supply connected to an outlet communicating with said flange, characterized in that the supply line opening into the bowl to direct a rinsing current is arranged in a direction substantially tangential to the substantially circular or ovoid circuit of the flange, the current being thus guided, in a laminar regime, with parallel threads, in a circular unidirectional path around the periphery of the flange, then the current continuing its movement downwards following the wall of the bowl in a spiral path, to the bottom of the bowl and thus licking all the walls and ensuring rapid entrainment of the contents of the bowl.
• the interior bottom of the bowl has walls conforming to a convex profile.
• the bottom of the bowl is shaped in a gentle slope from the periphery towards a substantially central cylindrical well for evacuation to the lower siphon.
• the slope of the bottom of the bowl from the periphery located directly above the flange, towards the central well is less than 12 °.
• connection of the gently sloping bottom of the bowl to the central well is made by a rounded shoulder.
• the circular well occupies a depth equal to one third of the height of the bowl, this height being defined on the one hand by the level of the upper edge of the bowl and on the other hand the level of the thread of water waiting in the bottom of the siphon.
• the depth of the well is at least
• the well is extended by a bent pipe forming a siphon and of diameter less than the diameter of the circular well.
• This siphon is advantageously itself formed by a pipe conforming to an elongated and continuous curved shape and of regular curvature; the radius of curvature of the siphon, following the narrowing connecting it to the bottom of the well, has an average radius of curvature of about 6cm.
• the water supply is programmed to limit the amount of water discharged and directed into the bowl during each evacuation, is not more than 3 or 4 liters.
• Figures 1 and 2 respectively show a longitudinal sectional view and a plan view of a toilet bowl with direct flush according to the prior art.
• Figure 3 shows a vertical cross-sectional view of a bowl according to the invention.
• FIG. 4 represents a view in longitudinal vertical section of a bowl according to the invention.
• FIG. 5 represents a view in horizontal section of such a bowl, according to the lines VV of FIGS. 3 and 4.
• Figures 6 and 7 show plan views of two alternative embodiments using a deflector.
• Figures 8 and 9 represent cross-sectional views of the udina and th e tan sver s with a variety of conformation of the basin of the central well.
• the invention is described below in the application to the field of toilet bowls, it is capable of being applied to any installation associated with a water supply and a water discharge, having to be rinsed and washed after each use so as to evacuate the deposited materials.
• the invention is likely to apply to the so-called "Turkish-style" toilet, to urinals, hospital drains, ...
• the invention aims to achieve new operating conditions for a toilet bowl so as to obtain an improved result compared to previous systems, from a minimum quantity of water and reduced to a level of the order of 3 to 4 liters maximum and can go down to 2 liters.
• the invention provides a bowl whose ecological functioning ensures a considerable reduction in water consumption in households or collective places.
• the outlet of the water supply in the bowl (1) is made from a pipe (2) of large diameter, corresponding - therefore without narrowing - to the diameter of the water inlet.
• the supply line 2 opens into the bowl, at the upper level of the flange (3), in a direction tangential to the substantially circular or ovoid circuit of the flange (3).
• the wall thus defines from its periphery (4) initially a gently sloping part (5) from the periphery to a well (6) substantially central or slightly offset towards the rear part of the bowl, as visible on the view in longitudinal section of FIG. 4.
• connection of the gently sloping part (5) to the well is made by a curved shoulder (7).
• the well therefore opens at its upper part at a level which is substantially in height in the middle of the bowl, this height being defined between the level of the upper edge of the flange (3) and the flow of water (8) in the bottom of the well.
• This well ends at its base with a narrowing from which the curviform circuit of the pipe (9) constituting the siphon (9a) starts.
• this driving aims to follow a regular and continuous route without modification of abrupt course.
• the radius of curvature of the first elbow affecting the pipe (9) forming the siphon is about 6cm.
• the water flow directed from a tangential direction through the outlet of the supply line marries in the bowl an initially circular or ovoid path, depending on the conformation of the bowl and its upper flange.
• This circular movement of the water streams allows circulation of the streams remaining parallel to themselves and following a laminar flow regime at high speed.
• the initial speed imparted to the current is not hampered by any obstacles, so that the kinetic energy accumulated in the circulating water makes it possible to effectively lick the walls by detaching the elements to be cleaned and evacuated.
• the circular movement then continues in the form of a spiral, gravity calling the water downwards while the circular movement remains imprinted on the circulating current.
• this movement restores the functioning of the natural forces of the flow of water from a capacity containing this water to a lower discharge opening according to the natural and spontaneous phenomenon of the spiral or vortex circulation.
• the evacuation forms a direct current and without parasitic multiturnbillon disturbance and braking or opposing each other.
• the twisted movement 1 lonnai r e is and remains unidirectional, thus conforming to a particularly efficient and stable cyclonic phenomenon since, moreover, it corresponds by strengthening it to the spontaneous play of the use of natural forces during the flow of fluids.
• the specific configuration of the bowl with a well of a significant height compared to the overall height of the bowl allows to quickly achieve, during the water supply, a degree of filling of the well as it exceeds the priming level of the siphon. Under these conditions, in addition to the play of the kinetic energy implemented by the unbraked stream of water and traversing in a continuous and spiraled way the walls of the bowl, there is a rapid call of the contents of the bowl resulting from priming the siphon.
• the invention allows under these conditions, in addition to the considerable advantages of saving city water consumed during each use, particularly advantageous conditions of operation on the hygiene plan, washing the bowl, including its front part, being perfectly done.
• the water is evacuated under particularly silent conditions.
• This silence is linked on the one hand to the laminar and undisturbed regime of the water streams flowing regularly from the feed to the siphon without cascading or bubbling effect linked to the antagonizing multi-vortex regime.
• the water indeed rotates regularly while being sucked down by gravity, in a circular spiral movement.
• the phenomenon employing a reduced amount of water and being very rapid it follows that the overall sound of the entire operation is considerably reduced, thereby providing improved comfort in premises using the device of the invention.
• the bowl can have a deflection wall (10) disposed either at the outlet of the water supply (Figure 6), or slightly offset before this outlet ( Figure 7).
• These deflection walls (or deflectors) direct the streams of water flowing after a first turn in the flange to bend them down and give them a path that is both spiral and helical; thus, the washing and evacuation current does not overlap in its path and, while avoiding a parasitic encounter, the streams of water with fast energy and speed scrape and effectively clean the walls.
• the rinsing water trickles remaining parallel to each other, from one turn to the next, along their helical and spiral course, there is no parasitic braking and no distortion in the rapid laminar flow.
• Figures 8 and 9 show a variant in which the curved shoulder 7a providing the transition between the gently sloping upper bottom (5a) of the bowl and the central well (6a) has a greater radius of curvature than in the example Figures 3 to 5.
• the flared conformation of the bowl and the central well substantially follows the shape of a sound horn as used in wind instruments or in old grammophones, promoting a regular flow of fluids.
• the bottom of the well is extended by the lower pipe bent in a siphon without narrowing to allow an accelerated flow towards the evacuation.
