URINAAUJÄRJESTELY

The invention relates to a vacuum-operated urinal arrangement according to the preamble of claim 1.

Prior art solutions typically have a complex structure comprising a multipart shell and a plurality of drive components on the backside of the wall supporting the urinal 10 shell. Another possibility has been to arrange a separate box or case for the utensils next to the urinal sheath. In addition, known urinals also have a water trap inside the urinal sheath. Thus, known urinal arrangements require relatively large space and are laborious and time-consuming to assemble and install, which makes all maintenance and the like very difficult to perform.

It is an object of the present invention to avoid the aforementioned disadvantages and to provide a streamlined and functionally effective urinal assembly. This object is achieved by the urinal arrangement 20 of claim 1.

The basic idea of the invention is to provide a urinal arrangement in which the actuating means can be enclosed and supported inside a substantially homogeneous casing portion of the urinal, the casing portion consisting of a bowl portion and a drain opening in the bowl portion 25 In this way, the urinal can be mounted and supported against the wall, whereby the urinal basically requires only an external vacuum connection for connection to the pipeline and a power supply connection.

Preferably, the drain opening is provided in fluid communication with a sensor chamber provided with a surface sensor device, wherein the sensor chamber is in fluid communication with a vacuum-operated drain valve member.

A preferred embodiment of the urinal arrangement further comprises rinsing water means supported within the shell portion.

The drive means is preferably mounted on a support plate which can be attached to the shell part.

The vacuum actuator is preferably operated by a vacuum which is derived from the piping via a vacuum supply valve.

Vacuum is provided to the pipeline by means of vacuum generating means and vacuum piping 15.

In order to facilitate the operation of the urinal arrangement, the drive means is connected to a control unit with an activation means.

The details of the invention will now be described, by way of example only, with reference to the accompanying schematic drawings, in which: - Figure 1 shows a portion of the urinal shell; Figure 2 shows a first embodiment of the drive means; Figure 3 shows a second embodiment of the drive means; and Figure 4 shows a general flow diagram of a urinal arrangement.

The present invention relates to a vacuum operated urinal arrangement, the operation of which will be described in connection with Figure 4.

In the figures, the casing portion of the urinal is generally designated by reference numeral 1. The casing portion 1, which according to the invention comprises a substantially uniform, e.g.

3 111978, a ceramic or steel body, is mounted against a wall or the like (not shown) in a manner known per se.

The actuating means 3 are mounted on a support plate 2 which is secured to the rear part 4 of the cover part 1 5 by means of fastening means, e.g. screws 5 or the like, the actuation means 3 being enclosed inside the outer boundaries formed by the cover part 1 and the support plate 2. The shell portion comprises a urinal bowl portion 11 having a drain aperture 12 approximately at the bottom of the bowl portion 11. The support plate can, of course, be attached to the same wall portion as the shell portion.

In the embodiment shown in FIG. is used.

The actuating means 3 further comprise a vacuum supply valve 35 which is in fluid communication with the piping 34 via a vacuum line 36 which: v: 20 the vacuum line leads to the pipeline 34 and respectively to the vacuum-operated drain valve 33 via the valve line 37. Vacuum ·. · Developed for the pipeline 34 by means of intermittent vacuum evacuation means 100 (Figure 4). Vacuum actuates a vacuum operated drain valve 33 via said vacuum supply valve 35 and vacuum and valve lines 36, 37;

The operation of the urinal arrangement will now be explained mainly with reference to Figure 4.

After urinalysis has been used and waste to be discharged into the urinal bowl portion 11, the user activates an activating means, e.g., a flush button 6, to initiate the flushing operation, thereby transmitting a signal to the vacuum generating means 100 via control unit 7, e.g.

Ejector device. This activates intermittent negative pressure generating means 10 100 which provide a specific vacuum, e.g., from about -18 kPa to about -35 kPa, to the vacuum piping 90, optionally comprising a discharge tank 91, and to the piping 34. , which is connected to the control unit 7. The operation of the vacuum generating means 100 is stopped when the desired vacuum level 15 is reached. Reference numeral 8 denotes the power supply socket of the control unit 7.

| When the prescribed vacuum level is reached, the control unit 7 activates the flushing water means 38, whereby the urinal bowl portion 11 is flushed, e.g. 20, with a specified amount of flushing water, e.g. 0.2 to 0.3 liters.

At the same time, the control unit 7 activates the vacuum supply valve 35 such that ·· vacuum is applied to the vacuum valve 33 from the piping 34 '·' via the vacuum line 36, said vacuum supply valve 35 and the valve line 37. This opens the drain valve 33, whereby the waste to be discharged is discharged from the urinal bowl portion 11 through the drain opening 12 and further through the sensor chamber 31 and the drain valve 33 to the piping 34 leading to the vacuum chamber 90 and drain tank 91.

»·

When the flushing operation is completed, the time controlled control unit 7>: · '30 closes the vacuum connection via the vacuum supply valve 35 to close the drain valve 33.

Alternatively, the flushing function may be activated by a surface sensor device 32 in the sensor chamber 31. The surface sensor device is preferably reacted with a certain amount, e.g., about 0.15-0.20 per liter of liquid, 5 waste to be discharged into the urinal bowl 12 and 32 is connected to the control unit 7 and arranged to send a signal to the control unit in a manner similar to the flushing button 6 described above to initiate the flushing operation.
