Definitions

  • the present invention generally relates to vacuum collection devices and, more particularly, to a vacuum-operated urinal.
  • urinal devices typically have a complex structure including a multipartite shell and with a number of operational components on the back side of a wall supporting the urinal shell. Some previous devices use a separate box or enclosure beside the urinal shell for the operational means. Previous urinals may also include a water trap within the urinal shell. Consequently, known urinal arrangements require a relatively large amount of space and the assembly and mounting of such urinals is laborious and time consuming, whereby also any maintenance or corresponding measures are made overly difficult.
  • An object of the present invention is to avoid the disadvantages of previous urinal arrangements and to achieve a streamlined urinal assembly providing a reliable function.
  • an arrangement for a urinal wherein a set of operational means can be enclosed and supported within a substantially unitary shell portion of the urinal.
  • the shell includes a bowl portion defining a discharge opening, whereby the operational means comprise a level sensor means and a vacuum operated discharge valve means in fluid communication with a pipe system.
  • the urinal can be mounted and supported on a wall, whereby the urinal basically only requires an outside vacuum sewer discharge connection, connectable to the pipe system, and a power supply connection.
  • the discharge opening is preferably arranged in fluid communication with a sensor chamber provided with the level sensor means, whereby the sensor chamber is in fluid communication with the vacuum operated discharge valve means.
  • An advantageous embodiment of the urinal arrangement further comprises a rinse water means supported within the shell portion.
  • the operational means are advantageously mounted on a back plate fastenable to the shell portion.
  • the vacuum-operated discharge valve means is advantageously operated by vacuum derivable from the pipe system through a first vacuum supply valve means.
  • Vacuum is provided to the pipe system by way of a vacuum generation means and vacuum sewer piping.
  • the operational means are connected to a control unit provided with an activator means.
  • FIG. 1 is a perspective view of a vacuum urinal assembly in accordance with the teachings of the present invention
  • FIG. 2 is a perspective view of a first embodiment of a set of operational means
  • FIG. 3 is a perspective view of a second embodiment of a set of operational means.
  • FIG. 4 is a schematic block diagram of a vacuum urinal connected to vacuum collection apparatus.
  • the present invention relates to a vacuum urinal assembly, the operation of which is discussed in connection with FIG. 4.
  • the shell portion of the urinal is generally indicated by reference numeral 1 .
  • the shell portion 1 which according to the invention comprises a substantially unitary body, e.g., of a ceramic or steel material, is mounted against a wall or the like (not shown) in a conventional manner.
  • the operational means 3 are mounted on a back plate 2 , which is fastened to the back side 4 of the shell portion 1 by fastening means, such as screws 5 or the like, whereby the operational means 3 are enclosed within the outer boundaries formed by the shell portion 1 and the back plate 2 .
  • the shell portion comprises a urinal bowl portion 11 with a discharge opening 12 approximately at the bottom of the bowl portion 11 .
  • the back plate could of course be fastened to the same wall portion as the shell portion.
  • the operational means 3 comprise a sensor chamber 31 , a level sensor 32 for monitoring the flush operation through the sensor chamber 31 , a vacuum-operated discharge valve 33 and a pipe system 34 , which is arranged to be connected to a vacuum sewer piping 90 (FIG. 4) by a discharge connection (not shown) at the location of the urinal.
  • the operational means 3 further comprise a first vacuum supply valve 35 that is in fluid communication with the pipe system 34 through a suction line 36 that taps into the pipe system 34 and respectively with the vacuum-operated discharge valve 33 through a valve line 37 .
  • Partial vacuum is created in the pipe system 34 by an intermittently operated vacuum generating means 100 (FIG. 4). The partial vacuum is used to operate the vacuum operated discharge valve 33 by way of said first vacuum supply valve 35 and the suction and valve lines 36 , 37 .
  • the second embodiment of the operational means 3 shown in FIG. 3 corresponds to the one disclosed in connection with FIG. 2 and further comprises a rinse water means 38 provided with a rinse water supply line 39 .
  • the rinse water means 38 provides rinse water to the urinal bowl portion 11 during a flush sequence.
  • the rinse water means 38 is preferably operated by vacuum by way of a second vacuum supply valve 40 , to which control vacuum is provided through vacuum line 41 (FIG. 4) from the vacuum generation means 100 .
  • an activator means for example a flush button 6
  • a flush button 6 is activated by a user in order to commence the flush sequence, whereby a signal is sent via a control unit 7 to the vacuum generation means 100 , e.g. an ejector means.
  • This flush signal activates the intermittently operated vacuum generation means 100 creating a given partial vacuum (e.g., from about ⁇ 18 kPa up to about ⁇ 35 kPa) in the vacuum sewer piping 90 , optionally including a retention tank 91 , and the pipe system 34 .
  • the partial vacuum level is controlled by a vacuum switch 71 connected to the control unit 7 .
  • the operation of the vacuum generation means 100 is shut off when the desired vacuum level has been reached.
  • Reference numeral 8 indicates a power supply connection for the control unit 7 .
  • the control unit 7 activates the rinse water means 38 (if provided), by way of the second vacuum supply valve 40 connected by the vacuum line 41 to the vacuum generation means 100 .
  • the rinse water means 38 delivers a given rinse water amount (e.g., approximately 0.2 to 0.3 liters) to the shell 1 , so that the urinal bowl portion 11 is flushed.
  • the control unit 7 activates the first vacuum supply valve 35 so that partial vacuum is directed from the pipe system 34 through the suction line 36 , the first vacuum supply valve 35 , and the valve line 37 to the vacuum operated discharge valve 33 . This opens the discharge valve 33 , whereby the disposable waste is discharged from the urinal bowl portion 11 through the discharge opening 12 and further through the sensor chamber 31 and the discharge valve 33 into the pipe system 34 which leads to the vacuum sewer piping 90 and the retention tank 91 .
  • control unit 7 After the flush sequence has been carried out, the control unit 7 , provided with a time control, will close the partial vacuum connection through the first vacuum supply valve 35 in order to close the discharge valve 33 .
  • the flush sequence may be activated by the level sensor means 32 provided in the sensor chamber 31 .
  • the level sensor means is preferably made responsive to a given amount of disposable waste (e.g., approximately 0.15 to 0.20 liters of fluid) collecting in the urinal bowl portion 11 and the discharge opening 12 .
  • the level sensor means 32 is connected to the control unit 7 and is arranged to provide a signal to the control unit 7 in a similar manner as the flush button 6 described above for commencing the flush sequence.
