Abstract
The present invention relates to an arrangement for a urinal for vacuum appli-cation comprising a shell portion (1), operational means, and vacuum discharge means. In order to achieve a streamlined arrangement the shell portion (1) comprises a substantially unitary body, whereby the operational means com-prise a level sensor means and a vacuum operated discharge valve means in fluid communication with a pipe system. The shell portion (1) is arranged to support the operational means within the shell portion.
Description
Arrangement for a Urinal The invention relates to an arrangement for a urinal for vacuum ap-plication according to the preamble of claim 1 .
Previously known solutions usually comprise a complex structure in-cluding a multipartite shell and having a number of operational components on the back side of a wall supporting the urinal shell. Another possibility has been to have a separate box or enclosure beside the urinal shell for the operational means. Furthermore, known urinals are also provided with a water trap within the urinal shell. Consequently, known urinal arrangements require relatively much place 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 said disadvantages and to achieve a streamlined urinal assembly providing a reliable function.
This object is attained by an arrangement for a urinal according to claim 1 .
The basic idea of the invention is to provide 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, comprising a bowl por-tion and a discharge opening in the bowl portion, whereby the operational means comprise a level sensor means and a vacuum operated discharge valve means in fluid communication with a pipe system. In this manner the urinal can be mounted and supported on a wall, whereby the urinal basically only re-quires 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 op-erated by vacuum derivable from the pipe system through a first vacuum sup-ply valve means.
Vacuum is provided to the pipe system by way of a vacuum genera-tion means and vacuum sewer piping.
In order to facilitate operation of the urinal arrangement the opera-tional means are connected to a control unit provided with an activator means.
In the following the present invention is described more in detail, by way of example only, with reference to the attached schematic drawings, in which:
Fig.1 shows a urinal shell portion, Fig. 2 shows a first embodiment of a set of operational means, Fig. 2 shows a second embodiment of a set of operational means, and Fig. 4 shows a general flow chart of the arrangement for the urinal.
The present invention relates to an arrangement for a urinal for vac-uum application, the operation of which is discussed in connection with Fig.
4.
In the figures 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 1 1 with a discharge opening 12 ap-proximately at the bottom of the bowl portion 1 1 . The back plate could of course be fastened to the same wall portion as the shell portion.
In the embodiment shown in Fig. 2 the operational means 3 com-prise a sensor chamber 31, a level sensor 32 for monitoring the flush operation through the sensor chamber, 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 oper-ated 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 com-prises 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 1 1 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 pro-vided through vacuum line 41 from the vacuum generation means 100.
The operation of the urinal arrangement is discussed in the follow-ing, mainly in connection with Fig. 4.
When the urinal has been used and disposable waste has been re-ceived in the urinal bowl portion 1 1, an activator means, for example 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 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 con-s trolled 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 connec-tion for the control unit 7.
When the given partial vacuum level has been reached the control unit 7 activates the rinse water means 38, by way of a second vacuum supply valve 40 connected by vacuum line 41 to the vacuum generation means 100, whereby the urinal bowl portion 1 1 is flushed, e.g. by a given rinse water amount, e.g. of about 0.2 to 0.3 litres. At the same time, the control unit 7 activates the first vacuum supply valve 35 so that partial vacuum is directed towards the vacuum operated discharge valve 33, from the pipe system 34 through the suction line 36, said first vacuum supply valve 35 and the valve line 37. This opens the discharge valve 33, whereby the disposable waste is discharged from the urinal bowl portion 1 1, 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 reten-tion tank 91 .
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.
Alternatively the flush sequence may be activated by the level sen-sor 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. about 0.15 to 0.20 litres of fluid, collecting in the urinal bowl portion 11 and the dis-charge opening 12. The level sensor means 32 is connected to the control unit 7 and is arranged to provide a signal to the same in a corresponding manner as the flush button 6 described above for commencing the flush sequence.
The drawings and the description related thereto are only intended for clarification of the basic idea of the invention. The invention may vary in 5 further detail within the scope of the ensuing claims.
