Definitions

  • the present invention relates to an installation of sanitary toilets of the direct evacuation and rinsing type without flushing effect or siphon.
  • the invention aims to achieve a WC installation avoiding the drawbacks of conventional systems operating by flushing effect, which require a large amount of water for each use.
  • the invention aims in particular to allow the installation of sanitary toilets under conditions and circumstances not allowing to have a large reserve of water for example and in particular on road or rail vehicles as well as in mobile homes (caravans, mobile homes, livable boats, etc.).
  • the present invention aims to develop the possibilities of sanitary installations of the WC type with direct evacuation and rinsing under pressure, in particular in the case of installations installed on road or rail vehicles generally having a supply of greased compressed air of 6 at 8 bars.
  • the installation according to the invention in fact makes it possible to benefit from the advantages of rinsing under pressure which makes it possible to obtain a cleaning of the installation between two uses, from a limited quantity of water and of the order of 25 cl.
  • the invention enables a system to operate fully automatically, the evacuation and rinsing cycle being triggered by a simple digital pressure from the user, without however requiring the use of electrical energy.
  • the installation of the invention uses exclusively both as a power source of power and as a source of control energy the compressed air drawn from the general equipment of the vehicle and which makes it possible to control the entire cycle without consuming d electricity, and therefore in conditions of total security and perfect reliability.
  • the invention relates to a set of sanitary toilets of the direct evacuation and rinsing type without flushing or siphon effect, the toilets being made up of a bowl of generally frustoconical shape comprising at the level of its small base in the lower position a hatch , controlled by a pneumatic cylinder, for intermittent communication with a discharge pipe, and the bowl also comprises at least one nozzle for spraying rinse and discharge water and coming from a pressurization chamber, and l installation is characterized in that it is connected to an energy source consisting of a source of compressed air communicating on the one hand with the pressurization chamber to ensure the high pressure supply of the nozzles (9, 9 ′) for rinsing and evacuation and on the other hand with the pneumatic cylinder (15) for operating the flap (14), this communication being ensured by a pneumatic register distributor (28) capable of regulating and controlling the evacuation cycle comprising the synchronized phases in the first place of opening of the hatch and projection of water under pressure and in the second place of closing of the hatch and
  • the installation consists essentially of a bowl 1, of generally frustoconical shape, resting on its small base 2.
  • This bowl will advantageously be made of polyester reinforced with sanitary white colored glass fibers.
  • the bowl is itself embedded in a casing block 3 which includes the bowl as well as the control assembly 4 (illustrated in detail in FIG. 2) and mounted on rails 5 resting on the base of the casing 6.
  • the base 6 may advantageously rest on the floor of the room by means of silentblocks 7, 7 ′, to avoid the transmission of vibrations.
  • the bowl In its upper part, the bowl has a rim oriented inwards and advantageously constituted by the extension of the upper horizontal face of the casing 3 comprising for this purpose a substantially elliptical solution of continuity and corresponding to the large base of the bowl 1.
  • the periphery of the bowl itself comprises, in a known manner, a double flap consisting of the bezel 10 and the cover 11.
  • an inclined plane 12 receiving the button 13 of the contactor 47 ensuring the control of the evacuation and rinsing cycle under the conditions which will be described below. -after.
  • the base 2 of the bowl comprises a closing hatch 14 of the "shovel valve” type and maneuvered in a substantially horizontal plane by a pneumatic cylinder 15.
  • the installation comprises a vertical pipe constituting the outlet for evacuation and the collection of effluents ending in a storage tank which could be disposed inside the casing 3 and which in the example produced is located below from the floor 16 of the installation, this tank 17 being connected to the lower evacuation pipe 18 by the communication sleeve 19.
  • the storage tank 17 itself comprises in the lower part an outlet formed by a flexible pipe 21 for the intermittent evacuation of the effluents stored between two periods of emptying.
  • a vent is planned in 20.
  • the installation is itself connected to a supply of clear water 22 comprising a suction strainer 23 at the end of the dip tube 24 and supplying the regulation assembly shown in FIG. 2.
  • the assembly is supplied with energy in the form of compressed air from the pipe 25 leading to the regulation and control block of FIG. 2 and connected to a source of compressed air greased 6 to 8 bars, available on the vehicle .
  • This block preferably mounted on a sliding plate on rails, so as to easily allow its upkeep and maintenance, is supplied with compressed air 6 to 8 bars by the pipe 25 previously described and in clear water by the pipe 24.
  • a pipe 26 is used for the evacuation of the compressed air in return and it ends at the base of the storage tank 17 where it opens out through the nozzle 27 by allowing, by the game of turbulence, the homogeneous distribution of the effluents within the tank.
  • the compressed air from the supply line 25 ends up at the distributor 28 of the sliding register type and allowing the intermittent distribution and distribution of the engine compressed air towards the operating members.
  • the distributor thus has two alternative outlets for pressurized air, namely a first outlet 29 and a second outlet 30.
  • the second outlet 30 leads to a second inlet (not shown) of the double-acting cylinder 15 for pneumatically controlling the hatch 14.
  • This double-acting cylinder ensures, when it is supplied by its second inlet through the pipe 30, the return of the hatch and the maintenance of this hatch towards its closed position.
  • the distributor is able to send the compressed air under pressure in the pipe 29 which itself leads to the two sub-pipes 29a and 29b thus supplied simultaneously.
  • the pipe 29a leading to the first inlet of the double-acting cylinder 15, retracts the hatch 14 and consequently opens the base of the bowl for the purpose of discharging the effluents.
  • the chamber 31 is supplied with clear water by the line 33 which allows both the reception of the water from the line 24 in the suction phase, through the non-return valve 34; while this same pipe 33 allows the evacuation of the pressurized water towards the pipe 35 leading to the projection nozzles 9, 9 ′ and 9 ⁇ , with the interposition of the non-return valve 36.
  • the chamber 31 comprises a piston 39 dividing the chamber into two capacities, namely a capacity 38 placed on the rear face of the piston and communicating precisely with the arrival of compressed air 29b.
  • the piston 39 is integral with a rod 40 projecting outside the chamber and comprising a helical spring 41 mounted at the periphery and coaxial with said rod; the spring 41 being compressed between the rear stop 42 secured to the terminal end of the rod 40 and the front stop 43 formed by the corresponding wall of the chamber 31.
  • a limit switch 44 connected on the one hand by the pneumatic line 45 to the compressed air supply source 25 and on the other hand by the pneumatic line 46 to the distributor.
  • the distributor is connected to a manual contactor 47 for controlling the start of the cycle, this contactor being controlled by the digital pressure of the user on the button 13.
  • This contactor is connected by a pneumatic inlet line 48 to the source of compressed air; this supply is obtained by the distributor 37 supplying from the line 25 on the one hand the distributor on the other hand the contactor 44 by the line 45 and finally the manual contactor 47 by the line 48.
  • the manual contactor 47 is in turn connected to the distributor by the pneumatic outlet pipe 49.
  • the pressure exerted on the button 13 ensures the communication of the inlet pipe 48 with the outlet pipe 49, while they are normally isolated in the rest position of the assembly; the result of this contacting is an initial pneumatic pulse sent to the distributor, which controls the start of the evacuation and rinsing cycle.
  • the operator triggers by a simple maneuver, without recourse to electrical control energy, on the one hand the opening of the hatch and at the same time the projection of a high pressure water along the walls of the bowl.
  • the high water pressure provides an immediate evacuation and rinsing effect from a limited amount of water which may not exceed 25 cl.
  • the opening and evacuation cycle is limited to a period of a few seconds, for example 5 to 6 seconds.
  • the end of cycle control is automatically ensured when all of the water reserve 32 has been evacuated under pressure to the nozzles; this end of the cycle is detected by the contactor 44 on which the stop 42 comes to bear, then corresponding to the positioning of the piston 39 at the end of the race when substantially all the water has been removed.
  • the contactor ensuring the communication of the inlet pipe 45 and the outlet pipe 46 allows the sending of a pneumatic pulse to the distributor 28 which returns the register to its initial position.
  • the pipe 30 then receives the pneumatic flow which is transferred to the first inlet of the double-acting cylinder 15 thereby ensuring the return of the hatch to its closed position and the maintenance of this hatch in the closed position.
  • the displacement of the piston 39 was made under the pneumatic pressure developed in the capacity 38, against the action of the spring 41; when the chamber 38 is no longer supplied with compressed air, the force of the return spring prevails and drives the piston 39 which is returned to its initial position; and in this movement the piston causes the call and the aspiration of the quantity of water 32, since in this phase the non-return valve 36 is in the closed position while the non-return valve 34 is in the open position ; the return of the piston and the aspiration of a perfectly dosed quantity of rinsing water are thus automatically obtained for future use and in the standby position in the pressurization chamber 31.
  • the distributor register is provided in such a way that it causes, under the action of the contactor 44, initially, the return of the hatch to its closed position while the interruption of the pressure water supply is delayed by a few fractions of seconds; thus obtaining the end of the cycle beforehand closing the hatch while a minimal quantity of water continues to be discharged from the nozzles, which ensures the maintenance of a film of water on the wall of the hatch; this gives a perfect seal of the bowl against odors on the one hand, while maintaining a film of water helps to ensure the cleanliness of the bottom of the bowl by preventing the formation of deposit.
  • the pneumatic control and regulation block will be grouped in a remote box relative to the device and to the bowl block; the box can be placed externally and in the immediate vicinity of the bowl block and the base of the bowl block is thus freed up to optionally house the effluent tank then integrated into the device.
