Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a urine storage device for vacuum application, as defined in the preamble of claim 1.

[0002]

2. Description of the Prior Art Previously known solutions usually involve a complex structure with a multi-piece shell, with several operating components on the back of the wall supporting the urine shell. It is a waste. Another possible method is
Providing another box or enclosure for the operating means on the side of the urine shell. In addition, known urinators also include a water trap within the urine shell. Thus, known urinary reservoir configurations require a relatively large area, and the assembly and installation of such urine reservoirs is laborious and time consuming, and maintenance and corresponding procedures are very difficult.

[0003]

This is achieved by the urine storage device according to claim 1.

[0004]

SUMMARY OF THE INVENTION The basic idea of the present invention is that a set of operating means can be stored and supported in a substantially integral urinal shell portion having a bowl portion and an outlet in said bowl portion. Providing the urine storage device wherein the operating means comprises vacuum operated drain valve means in fluid communication with the level sensor means and the pipe system. In this way, the urine can be mounted on and supported against the wall, which basically only needs an outer vacuum sewage drain connection and a power connection connectable to the pipe system.

The outlet is preferably configured to be in fluid communication with a sensor chamber that includes level sensor means, the sensor chamber being in fluid communication with the vacuum operated exhaust valve means.

An advantageous embodiment of the urine storage device further comprises wash water means supported within the shell portion.

The operating means is advantageously mounted on a back plate which can be fixed to the shell part.

Advantageously, the vacuum operated discharge valve means is operated by a vacuum which can be induced from the pipe system via the first vacuum supply valve means.

A vacuum is provided to the pipe system by vacuum generating means and vacuum sewage piping.

To facilitate the operation of the urine storage device, the operating means are connected to a control unit equipped with activator means.

In the following, referring to the attached schematic drawings,
The invention will be described in more detail by way of example only.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a urine storage device for vacuum applications, the operation of which will be discussed with respect to FIG.

In the figures, the shell portion of the urine reservoir is indicated generally by the reference numeral 1. This shell part 1 comprises, according to the invention, a substantially monolithic body, for example of ceramic or steel material, which is attached to a wall or the like (not shown) in a conventional manner.

The operating means 3 is a back plate 2 fixed to the back surface 4 of the shell part 1 by a fixing means such as a screw 5.
Mounted on, the operating means 3 are housed within the outer boundary formed by the shell part 1 and the back plate 2. The shell portion includes a urine storage bowl portion 11 having a discharge port 12 substantially at the bottom of the urine storage bowl portion 11. The back plate can, of course, be fixed to the same wall as the shell.

In the embodiment shown in FIG. 2, the operating means 3
Is a sensor chamber 31, a level sensor 3 for monitoring flash operations through the sensor chamber.
2, a vacuum operated drain valve 33, and a pipe system 3 configured to be connected to a vacuum sewage piping 90 (FIG. 4) by a drain connection (not shown) at the location of the urine reservoir.
4 is provided.

The operating means 3 is further in fluid communication with the pipe system 34 via a suction pipe 36 which taps into the pipe system 34, and with a vacuum operated discharge valve 33 and a fluid via a valve pipe 37 respectively. A first vacuum supply valve 35 that communicates is provided. Vacuum generating means 1 operated intermittently
00 (FIG. 4) creates a partial vacuum in the pipe system 34. This partial vacuum is used by the first vacuum supply valve 35, the suction pipe 36, and the valve pipe 37 to operate the vacuum operation discharge valve 33.

The second embodiment of the operating means 3 shown in FIG. 3 corresponds to that disclosed with reference to FIG. 2 and further comprises a wash water means 38 with a wash water supply pipe 39. The flush water means 38 provides flush water to the urine bowl portion 11 during the flush sequence. The wash water means 38 is preferably operated in a vacuum by a second vacuum supply valve 40, which has a control vacuum from the vacuum generating means 100 through a vacuum tube 41.
cumum) is brought about.

The operation of the urine storage device is discussed below, primarily with reference to FIG.

When the urine is in use and a treatable waste is received in the urine bowl 11, the user activates the activator means, eg the flash button 6, to initiate the flush sequence. , Thereby sending a signal via the control unit 7 to the vacuum generating means 100, e.g. evacuation means. This causes the intermittently operated vacuum generating means 100 to be started, in a vacuum sewage piping 90 and a pipe system 34 optionally comprising a holding tank 91, for example, for a given amount of about -18 kPa to about -35 kPa. Create a partial vacuum. The level of partial vacuum is controlled by a vacuum switch 71 connected to the control unit 7. When the desired vacuum level is reached, the operation of the vacuum generating means 100 is shut off. Reference numeral 8 indicates a power supply connection for the control unit 7.

When a given partial vacuum level is reached, the control unit 7 activates the flush water means 38 by means of a second vacuum supply valve 40 connected to the vacuum generating means 100 by means of a vacuum tube 41, whereby urine storage The bowl part 11
For example, it is flushed with a given amount of water, for example about 0.2-0.3 liters. At the same time, the control unit 7
Of the vacuum supply valve 35 of the pipe system 34 so that a partial vacuum is drawn from the pipe system 34 to the suction pipe 36, said first
Through the vacuum supply valve 35 and the valve pipe 37, and is sent to the vacuum operation discharge valve 33. As a result, the discharge valve 33 is opened, and treatable waste is passed from the urine bowl portion 11 through the discharge port 12, the sensor chamber 31 and the discharge valve 33 to the vacuum sewage piping 90 and the holding tank 91. It is discharged into the open pipe system 34.

After the flash sequence is performed,
The control unit 7 with time control closes the partial vacuum connection through the first vacuum supply valve 35 in order to close the discharge valve 33.

Alternatively, the flash sequence may be provided by a level sensor means 32 provided within the sensor chamber 31.
It can also be started by. The level sensor means are preferably urine bowl portion 11 and outlet 12.
Is responsive to a given amount of treatable waste collected from, for example, about 0.15 to 0.20 liters of fluid. The level sensor means 32 comprises a control unit 7
And is configured to send a signal to the control unit 7 in a manner corresponding to the flash button 6 described above for the start of the flash sequence.

The drawings and their associated description simply refer to
The purpose is to clarify the basic concept of the present invention. The invention can be modified in further details within the scope of the following claims.
