  • the present invention aims to remedy these drawbacks and will make it possible to produce sanitary toilets of the WC type with substantially conventional operation and consequently avoiding putting off the user in his habits, while allowing considerable savings in the water used for rinsing. of the bowl.
  • the evacuation will be carried out by gravity and without flushing effect, while a a limited and metered dose of liquid, for example clear water, will be used to obtain, thanks to a powerful effect of projection under pressure, the effective rinsing and therefore the return to a clean and hygienic appearance of the bowl.
  • liquid for example clear water
  • the invention uses only a reduced quantity of water for each use, making it possible to reduce the quantity of water necessary for each use, in a proportion of 40 to 1; which represents a considerable saving.
  • the device can be fixed on a support (cabin) or integrated into a mobile assembly which will not necessarily be connected to a city water source.
  • the device will thus advantageously be able to equip a movable construction hut, a caravan or any mobile dwelling; and the device may be in these conditions replenished with water in a limited quantity, without requiring, moreover, that the water is necessarily potable, clear water (for example recovery water for rinsing or body washing can be perfectly used for this end).
  • the invention relates to a sanitary toilet installation of the WC type with direct evacuation by gravity and rinsing with liquid without flushing effect, characterized in that it comprises a bowl substantially matching the shape of a body of revolution of section decreasing from its open upper part, forming the seat, towards the base, comprising a discharge opening, and in that said bowl comprises means for spraying a limited dose of rinsing liquid in the form of a jet under pressure espousing a volume specific to irrigate at least the entire lower half of the wall of the bowl, and said means are mounted movable between an active position or projection position disposed in the vertical axis of the bowl and a cleared position or inactive position.
  • said means for projecting a limited dose of rinsing liquid consist of a nozzle connected to a source of pressurized liquid.
  • the means for spraying rinsing liquid are mounted integral with a member forming a folding lid and articulated relative to the body of the bowl, so as to allow pivoting, in a manner known per se, between a position of overlay and shutter of the bowl seat and a position leaving this seat clear for the period of use.
  • the projection means consisting of a nozzle, are mounted integral with the underside of the flap cover, that is to say of the wall facing the interior space of the bowl in the folded position of said cover.
  • the nozzle is capable of projecting a set of multidirectional rinsing water jets, the jets together forming a volume of revolution serving at least the lower half, and preferably the lower two-thirds of the inner wall of the bowl.
  • Said multidirectional jets will in particular form a cone with an angle at the top equal to or greater than 150 °.
  • the base of the bowl communicates with an intermediate chamber forming an airlock and comprising at its upper part a valve. upper separation with respect to the interior space of the bowl and at its lower part a lower valve isolating said chamber from means for evacuating and storing materials from the bowl.
  • the upper valve is shaped as an articulated pallet and returned to the horizontal position to close the bottom of the bowl and said pallet is for this purpose associated with a return member such as a counterweight and the pallet is thus able to pivot between a horizontal closing position, closing the bottom of the bowl, and a substantially vertical cleared position leaving the passage between the interior space of the bowl and the intermediate chamber open, the restoring force being tared so as to yield and allow the pivoting of said pallet under a force of a few grams.
  • the lower valve of the intermediate chamber is constituted by a cover of the shovel valve type, sliding along a horizontal plane being subjected to the action of an operating cylinder to allow the isolation of the intermediate chamber by relative to the discharge means or alternatively the passage of the materials from the chamber to said downstream discharge means.
  • the nozzle is supplied with liquid in metered quantities, by an electric turbine supplied with water and directing towards said nozzle, by a connecting pipe, a flow of pressurized liquid.
  • the nozzle is supplied with pressurized liquid from a pneumatic compression chamber, receiving the liquid in metered quantities from an intermediate capacity, itself connected to a reservoir, the intermediate capacity comprising solenoid valves so as to discharge into said compression chamber a quantity of metered water corresponding to the volume of said capacity, the compression chamber also receiving a flow of propellant gas such as pressurized air and thus being able to direct a flow of liquid under pneumatic pressure.
  • a pneumatic compression chamber receiving the liquid in metered quantities from an intermediate capacity, itself connected to a reservoir, the intermediate capacity comprising solenoid valves so as to discharge into said compression chamber a quantity of metered water corresponding to the volume of said capacity, the compression chamber also receiving a flow of propellant gas such as pressurized air and thus being able to direct a flow of liquid under pneumatic pressure.
  • the assembly advantageously comprises a control member capable of causing the opening of the lower valve of the intermediate chamber in a first step for the removal of the materials, and in a second step, determined by the end of opening stroke. of said lower valve, the projection of the rinsing liquid by placing the nozzle in communication with the source of rinsing liquid under pressure, the liquid thus being brought into the projection position from the nozzle towards the interior walls of the bowl.
  • the cover includes a safety contactor opening the electrical circuit for evacuation and rinsing control, when said cover is in the open position and corresponding to the position of use, the contactor thus preventing the operation in its open position. rinsing water projection devices, the folding down of the flap cover causing the closing of the electrical circuit and authorizing in this position the initiation of the evacuation and rinsing operations.
  • the bowl, the source of pressurized liquid, the actuating cylinder of the lower valve of the intermediate chamber, and this intermediate chamber are together included in a casing forming the enveloping body, the sides of this casing being able to rest on the ground by fixing means and joining in their upper part, at least on the front face, opposite the articulation of the flap cover, the cylindrical periphery of the upper edge of the bowl forming the seat.
  • the flap cover has in its thickness a rinsing water supply circuit terminating in the spray nozzle, the circuit terminating on the opposite side to a rotating joint disposed in the articulation axis of said flap seat and joining the source of pressurized liquid.
  • a particular feature corresponding to an embodiment of the device according to the invention provides that the intermediate chamber is formed by a cylinder fitted by its apex at the base of the frustoconical outer wall of the bowl with the interposition of a seal, the base of the bowl and its shutter valve being thus positioned inside said intermediate chamber.
  • the device thus described constitutes an autonomous assembly not connected to an external water source, and for this purpose the device comprises a terminating rinsing water tank. , by circuits suitable for the source of pressurized water.
  • the sanitary installation generally designated by FIG. 1 comprises a bowl of generally frustoconical shape 2; this bowl is essentially in the form of a volume of revolution and could therefore be constituted in the form of a spherical cap; its diameter decreases from its open upper part 3 corresponding to the seat 4, to its lower part 5, the base of which is open, by receiving a closing valve 7, to allow the evacuation of the materials from the interior space 8 of the bowl.
  • the bowl itself can be made of any suitable material, in particular stainless steel, synthetic material or resin, or ceramic.
  • a flap cover 9 is articulated on the bowl along an edge of the latter, the hinge axis being for example tangential to the circular edge of the seat 3.
  • the flap cover 9 is thus pivotally mounted according to its articulation 10 between an inactive position as shown in solid lines in FIG. 1, corresponding to the position of use, the user then being in a sitting position on the seat, and a position folded down as shown in dotted lines.
  • the flap cover may include a simply mechanical, magnetic, electrical or pneumatic locking system, and of a type known per se, making it possible to lock the flap 9 in a stable position in a vertical position corresponding to the position of use.
  • the assembly is contained in an envelope or casing 11 whose folded upper edges 12 include and close the upper edges 3 of the bowl, these upper edges 11 constituting the user's rest seat in position for using the bowl.
  • the rim 12 forming a seat receiving, in its folded position, the support of the flap cover 9 as seen in dotted lines in FIG. 1.
  • the outer periphery 5 of the bowl 2 is engaged in a cylindrical chamber 13 forming an intermediate chamber or airlock between the interior space of the bowl and the downstream evacuation means 14.
  • downstream evacuation means will not be described here since they are not critical in carrying out the invention and they may simply consist of a conduit leading to a lower container for the temporary storage of materials, or even to a conduit leading by gravity to any enclosure or discharge system to outside, for example, an enclosure for recovering and treating used materials with a view to their bacterial digestion and fermentation with the implementation of a methanogenesis cycle.
  • the intermediate chamber 13 is connected to the outer wall of the bowl 2 by a seal in a manner known per se.
  • the chamber 13 therefore internally receives the base 5 of the bowl 2 and the closure device 7.
  • This closure device consists of a pallet pivotally mounted according to arrow 7 ′ and for this purpose the pallet 7 is articulated along a horizontal axis and it is associated with a return device for example a counterweight; the recall is tared so that the pallet 7 yields under a light weight of a few grams; under these conditions the pivoting pallet 7 is maintained in the closed position closing the bottom of the bowl and it can receive a permanent film of water a few millimeters thick.
  • the chamber 13 communicates with the exhaust duct 14 with the interposition of a lower valve 15; the latter consists of a sealing cover as used in devices of the "shovel valve” type and it is therefore formed of a horizontal cover sliding in its plane and maneuvered by the jack 16, this cover being movable between a retracted position in which the intermediate chamber 13 communicates with the discharge duct 14 and a closed position isolating the intermediate chamber with respect to said duct.
  • the flap cover 9 has on its lower face (in the folded position of said cover) a nozzle for projecting liquid jets.
  • This nozzle 17 communicates with an inner conduit 18 embedded in the mass of the cover 9 and leading to a transverse rotary joint 19 located along the axis of articulation 10 and making it possible to connect the conduit 18 (pivoting with the cover 9) to a source fixed pressure water supply.
  • the nozzle is designed to spray jets under liquid pressure, in particular clear rinsing water, according to a set of multidirectional jets together taking the form of a cone whose angle at the top is at less than 150 °.
  • liquid under high pressure will serve and irrigate from the central position of the nozzle 17, the whole of the lower part, and preferably at least the lower two-thirds of the wall of the bowl.
  • the jets Due to the central position of the emission point, its proximity to the surface of the inner wall of the bowl and their angle of attack, the jets arrive on said wall with a force and a powerful impact thus allowing to detach from the wall any projection which would be there and thus ensuring the perfect cleaning of this surface, this for a low water consumption; the force of impact of the liquid allowing an immediate action, the liquid being moreover quickly evacuated towards the lower chamber 13 and beyond towards the conduit 14, entraining all the deposits thus removed and detached from the wall of the bowl.
  • the source of pressurized liquid could be constituted by a pressure cleaner, that is to say an electric turbine receiving water from a reservoir (not shown) and directing this water under high pressure towards the nozzle 17 by the circuits. 18.19 previously described.
  • the source of pressurized water is constituted by a compression chamber 20, shown in FIG. 4; this compression chamber is supplied with clear water from the circuit 21, leading to the metering capacity 22, which is interposed between the two solenoid valves 23 and 24 respectively.
  • the clearance of the two solenoid valves is controlled successively so that after filling the metering capacity 22, the solenoid valve 24 is open while the solenoid valve 23 is closed so that the quantity of water flows into the chamber 20 corresponding to the volume of capacity 22.
  • a carrier or propulsion gas constituted for example by compressed air this source of compressed air may be produced either by an additional compressor or from a source of compressed air existing nearby, for example on a vehicle, a boat, etc.
  • the opening of the solenoid valve 26 therefore allows the exhaust to the conduits 18, 19 supplying the nozzle 17, of water under high pressure of clean air to cause consequently the projection of the jets of pressurized water from the nozzle 17 by serving the interior walls of the bowl.
  • the materials being deposited in the intermediate chamber 13, by tilting the pallet 7, the putting into operation of the evacuation and rinsing device can then be triggered.
  • This triggering takes place on the action of a push button with digital control (not shown) and positioned for example within easy reach on the casing 11; a contactor could also be actuated automatically by the pivoting movement of the cover brought from its released position to its folded position.
  • the triggering as a result of the initial signal as described and controlled above, initially operates the actuation of the actuator 16 and consequently the retraction of the valve closure cap 15; when the cover is in the fully released position, therefore at the end of stroke of the jack 16, the signal of the rinsing operation intervenes and an electrovalve, for example the electrovalve 26 puts the source of pressurized water in communication with the nozzle 17 consequently causing the arrival at the nozzle 17 of the pressurized water and the projection of a plurality of multidirectional jets as previously described by consequently triggering the rinsing of the bowl with the evacuation of the projections and adhering deposits on the walls of the latter; during all this time the cover of the lower valve 15 remains in the open position so that the outlet is thus released, the valve 7 itself being in the erased position due to the flow of water which flows from the nozzle.
  • an electrovalve for example the electrovalve 26 puts the source of pressurized water in communication with the nozzle 17 consequently causing the arrival at the nozzle
  • valve 7 closes, retaining the few grams of water, that is to say a film ensuring the maintenance of a wet screen on the wall of this pallet (thus facilitating its subsequent cleaning).
  • the closing signal is sent to the jack, for example an electric jack 16 which brings the cover of the lower valve 15 back to its closed position, thereby isolating the intermediate chamber 13 from the downstream circuit 14.
