Definitions

  • a Water closet installation comprises the following essential elements: a commode with seat and mobile lid associated with a tank or reservoir of water by means of a pipe of a, relatively critical diameter, called a flush-pipe, and a system of ventilation evacuating the foul air from the room.
  • a water pipe supplies the reservoir with water; its filling is regulated by means of a float ensuring the filling so long as the valve is closed; the aforesaid valve is associated with a lever and a chain, which is pulled down by the user. Water is flushed in the commode, to evacuate the stool.
  • the aforesaid reservoir is filled with 'water or is being filled when in use or in a contrary case the tank may be empty in order not to let the water in the reservoir freeze in winter. In this case, the tank is iilled only when pulling the chain, the ush functioning automatically under the action of the float.
  • the present invention proposes a system which functions automatically by employing a proximity detector in the [form of a photoelectric cell and light beam which comprises an electromechanical mechanism to actuate the chain for flushing.
  • the present invention further includes means to overcome the adherence of the stool to the interior of the commode.
  • use is made of the conventional flush pipe in evacuating foul air by including means delivering an air blast in a direction opposite to the movement of the water, whereby the odors are removed in a rst stage and the flushing occurs in a stage immediately thereafter.
  • the principal object of the invention consists of modifying the function of the usual flush-pipe in order to evacuate the foul air -when produced, in the interior of the commode, by means of an air-blast in the direction opposed to the water-flush direction, the water-flush being applied after the air blast.
  • the common flush-pipe accomplishes a rapid abduction of foul smells in the first phase and a water-flush thereafter.
  • Another object of the invention is to provide the automatic operation of water closet installation.
  • the invention makes use of a proximity-detection device such as a photoelectric cell or an electronic proximity-detector of the type in which the detecting ele- Patented Sept. 20, 1971 ment consists in a reactance element of an oscillating high-frequency circuit whose reactance changes due to nearness of the users body.
  • a proximity-detection device such as a photoelectric cell or an electronic proximity-detector of the type in which the detecting ele- Patented Sept. 20, 1971 ment consists in a reactance element of an oscillating high-frequency circuit whose reactance changes due to nearness of the users body.
  • Such electronic proximitydetectors make use of the hinges of the toilet seat as a means which cooperates with the electrical mechanism in initiating the flushing and air blast operations.
  • Another object of the present invention is to provide automatic means cooperating with the toilet seat when the toilet seat is in one of two positions, either raised or lowered, so that the movement into these positions will close and open the valve which flushes the toilet.
  • the airblast cannot be provided solely by the aspiration of the ascending contaminated air and it is necessary to provide forced aspiration by means of an exhaust to the exterior of the building by means of a jet ejector or an hydraulic motor driving a ventilator rotor, the said motor being for instance a geared or a blade-motor or a small hydraulic turbine, the choice being dependent on the water pressure.
  • the jet ejector is a simple and well-known structure which is low in cost and reliable, and the operating principle is 'well-known.
  • the carrying fluid in the jet ejector enters into a converging throat which lies along the axis of a Venturi bicone or nozzle whereby a diminished pressure is created between the converging cone and the nozzle, cause aspiration.
  • the output of these jet devices steadily increase with increasing pressure (especially Koerting and Y. E. Thompson ejectors).
  • the combination of plastic air-ejector and turbine serves as a simple and unique control means which combines the action of the jet in the interior of the Venturi bicone and the Ventilating means of the second device.
  • FIG. l represents a typical global installation, in Which the air-blast system is a jet ejector
  • FIG. 2 represents another installation in which the airblast system comprises a jet ejector and an air-turbine;
  • FIG. 3 represents schematically two other different solutions for the Hush and the air-blast, appropriated to certain cases.
  • FIG. 4 represents schematically a pan and a reservoir for conventional flush, with the flush-pipe comporting a by-pass opening on a ventilator.
  • the water closet equipment comprises a reservoir 1 with tank cover 1a, inlet waterpipe 3 serving to lill the reservoir, a ush-pipe 5 and a commode 7 with its seat 20 and its lid 21.
  • the pipe 5 opens at one end thereof into the commode 7 and the lowermost extremity of the flush-pipe 5 is fitted with a diffuser 6.
  • the other end of the flush-pipe S extends into reservoir 1 at a level which is slightly higher than the level designated by line N of FIGS. 1-3 of the drawing which represents the level of the fwater in the reservoir When full.
  • the upper part of pipe 5 is formed as a Venturi casing portion 9 in the interior of the reservoir 1.
  • the base of this Venturi casing portion 9 is pierced with Several apertures 11, distributed al1 around of its wall.
  • the part 9 of the pipe 5 is coaxially enclosed with a freely sliding piece of pipe 13.
  • Disposed below the lower edge of sliding pipe 13 which surrounds the Venturi casing 9 and is coaxial with the pipe 5 are the openings 11, these openings forming a communicating passageway for water in the reservoir between pipe and casing 9.
  • the upper extremity of the pipe 13 ends by a flange 33 under which is inserted, coaxially with the pipe 13, a fioat 14, having the form of a big cork or expanded plastic ring.
  • the cover 1a closing the reservoir 1 with the aid of a tightness joint 2 comprises a tubular opening 1b, on which is forced a tubular passage 55 ⁇ whose upper extremity 55h opens at the exterior of the local.
  • the cover 1a also comprises a deector 17 comprising a central conical projection 17a in the axis of the pipe 5 and a circular projection 17b.
  • a solenoid valve 39 with electromagnet 39a and a press-button 39! for handoperation, in the case of failure of electric current.
  • a pressure stream of water is established Which bursts from the nozzle 19 to pass upwardly through the Venturi bicone and impinge above onto deector 17, which throws the water stream back into the reservoir around the flush-pipe aperture.
  • the space separating nozzle 19 from Venturi bicone 18 is the region of diminished pressure which induces the aspiration of the air carried along with the water jet thereby causing a compression at the reservoir interior and rejecting air in the evacuation passage. This creates consequently a continuous upwardly moving air-blast from the commode which is established from the beginning of the flushing operation, effectively initiated at the same time as one uses the seat.
  • This air-blast occurs during the time the reservoir is -filling and the relatively brief water-Hush constitute a cycle of operation. Prolonged use of the commode may require several cycles, it may suflice to push on the press-button of the solenoid valve.
  • FIG. 1 When examining FIG. 1 one can distinguish a small water pipe 10, establishing a communication between the bottom of the reservoir 1 and the flush pipe 5 by means of a valve 12, destined to regulate the output.
  • a small tube 16, represented in dotted line, can establish a direct communication between the pipe and the diffuser 6, which is destined, beside its principal function, to direct the surplus of water coming from the reservoir to the impact-point of the stool, in order to clean the adherence of faeces to the porcelain of the commode.
  • This water surplus from the reservoir permits a greater water output coming from the nozzle which gives to this later a greater efciency, when considering the time necessary to the filling of the reservoir determining the duration of the above-mentioned cycle.
  • the different systems automatic the functioning of the installation is illustrated in FIG. l.
  • Commode 7 is provided with a seat 20 and its mobile lid 21, respectively connected through hinges 25 and 25a to the fixed part 22 of the commode 7. Part 22 and commode 7 are secured together by screws 47.
  • a rod 26 of insulating material fixed by one of its extremities to the mobile lid 21 comports at one end a sector 27 of conducting metal forming the mobile blade of an electrical contactor having two fixed blades 28 and 29.
  • This electrical contactor is serially connected with an electromagnet 39a which is controlled by means of armature 39C and solenoid valve 39.
  • the mobile lid 21 can occupy different positions beside its functional position acting as a lid; the dotted line 24 corresponds to a vertical position, or approaching, in ⁇ which case the contactor closes the electric circuit and the dotted line 23 corresponds to the extreme lid position, in which the drawback spring 30 is compressed and the aforesaid circuit open.
  • the user finds the mobile lid lowered on the commode, and as consequence, the device at stop.
  • the raising up of the lid till the vertical position establishes the contact closing the electric circuit of the solenoid valve and puts in operation all the air-blast and water-flush device.
  • the lid is lowered, as it ought to be and consequently the device will come to a stop automatically,
  • FIG. l one can see at the right of the lid a source of light 45 disposed judiciously above the commode, and facing it, a photoelectric cell 43, not visible in FIG. l, but clearly represented in FIG. 3.

  • the distributor includes an oscillator comprising an inductor and a capacitor one armature of which is connected to the proximity-electrode. As is well-known the presence of a target, here the user, untunes the oscillator which produces a control signal.
  • the user influences and controls the iiushing operation by a capacitative effect, which is a function of the proximity of the electrode, energizing a variation in his tuning of the oscillator.
  • the oscillator detuning energizes the closing of the electric circuit controlling the solenoid valve.
