Description
VACUUM SEWER SYSTEM
The present invention relates to a vacuum sewer system comprising a sewage receptacle, sewer piping, a discharge valve between the sewage recepta- cle and the sewer piping, means for generating partial vacuum in the sewer piping, and a rinse water arrangement.
More particularly the present invention relates to a rinse water arrangement for a sewage receptacle, e.g. a sanitary unit such as a toilet bowl or a urinal, comprising a rinse water supply, a rinse water valve and a rinse water distribution means.
Previously known rinse water distribution means usually include a spray ring, provided e.g. with apertures or nozzles, that encircles the inside of the sanitary unit. Such a spray ring or tube is generally placed under a downward, i.e. toward the bottom or discharge outlet of the unit, turned flange or collar, e.g. a seat ring in a toilet bowl, in order to protect it from outside manipulation. Conventional units are generally provided with such flange or collar structures. The spray ring or tube is on the other hand used to ensure that rinse water is distributed over the whole interior surface of the sanitary unit or bowl. An alternative solution has been to place a number of individual nozzles around the circumference of the interior side of the unit.
There are also solutions with a single nozzle at the back or end wall of the unit. This arrangement, however, does not provide a satisfactory spread of rinse water.
Particularly in connection with vacuum sewer system arrangements, e.g. vacuum toilet units, aeration of the unit also has to be provided for in order to avoid that a user gets stuck to the unit when using the same. In prior art solutions the aeration apertures or openings have usually been disposed under a typical flange or collar structure as described above.
The prior art rinse water distribution means have required an additional number of parts or additional working measures, such as arranging apertures in
the unit. When simplified solutions have been sought, the rinse function of the unit has been unsatisfactory.
The object of the present invention is to avoid the above mentioned drawbacks and to provide a vacuum sewer system, in which the sewage recepta- cle is properly rinsed during a flushing sequence and does not cause undesired effects with respect to the user. Another object is to provide a rinse water arrangement that gives a secure function by simple means. A further object of the invention is to secure adequate aeration in all conditions of use of the unit. These objects are attained by a vacuum sewer system according to claim 1 and a rinse wa- ter arrangement according to claim 3.
The basic idea of the invention is to provide a dual function rinse water arrangement for controlled distribution of rinse water and controlled aeration, whereby the rinse water distribution means comprises a rinse water nozzle with a first inlet for receiving rinse water and a first outlet for distributing rinse water and an adjacent first opening and second opening for aeration of the sewage receptacle. Such a rinse water arrangement is especially suitable for a sewage receptacle in a vacuum sewer system.
Preferred embodiments of the vacuum sewer system including a rinse water arrangement are defined in claim 2. Preferred embodiments of a rinse water arrangement are defined in claims 4 to 13.
In the following the present invention will be described in more detail, by way of example only, with reference to the accompanying schematic drawings, in which Fig. 1 shows a vacuum sewer system employing a rinse water arrangement,
Fig. 2 shows more detailed view of a sewage receptacle,
Fig. 3 shows an interior side view of a rinse water nozzle,
Fig. 4 shows a sectional view of the rinse water nozzle, Fig. 5 shows section A-A indicated in Fig. 3,
Fig. 6 shows section B-B indicated in Fig. 3, and
Fig. 7 shows a perspective view of the rinse water nozzle. The vacuum sewer system 100 shown in Fig. 1 comprises a sewage receptacle 101 , e.g. a sanitary unit 1 , sewer piping 102, a discharge valve 103 between the sewage receptacle and the sewer piping and means 104 for generating partial vacuum in the sewer piping. The operation of the discharge valve 103 is controlled by a control means comprising a control mechanism 105 provided with an activating means 106. The vacuum sewer system further includes a rinse water supply 107, a rinse water valve 108 and a rinse water distribution means 109 for providing rinse water to the sanitary unit. Fig. 2 shows an interior side view of the sanitary unit 1 , i.e. in this embodiment shown as a toilet bowl provided with an outlet. The sanitary unit has an interior surface 2, which leads downward into a discharge outlet 3. A rinse water nozzle 4 is mounted in the back wall portion 5 of the sanitary unit 1. The interior surface 2 is provided with a shelf 6, which extends around the circumference of the interior surface, partly or wholly, at a given distance from the upper edge 7 of the sanitary unit 1. A rim, ridge or groove may be used instead of the shelf. The purpose of this feature is to carry the rinse water distributed from the rinse water nozzle 4 along the interior surface 2 of the sanitary unit 1 before it flows down toward the discharge outlet 3 along the interior sidewall portions 8 of the sanitary unit 1 thus improving the distribution of rinse water over the interior surface 2. Said shelf, rim, ridge or groove is an optional complement to the improvement of the rinse water distribution. Basically the rinse water distribution may be controlled by the pressure of the supply of rinse water and the configuration of the nozzle.
Fig. 3 shows a side view of the rinse water nozzle 4 and Fig. 4 shows a sectional view of the rinse water nozzle. The rinse water nozzle 4 comprises an elongated body part 41 with a first end 42 and a second end 43. The first end 42 of the rinse water nozzle 4 comprises a first inlet 44 leading to a first bore 45 extending toward the second end 43 providing a first outlet 46. The first end 42 further comprises a first opening 47 leading to a second bore 48, parallel with the first bore 45, extending towards the second end 43 providing a second opening 49.
The first outlet 46 forms a rinse water (indicated by unfilled arrow in Fig. 4) spreading means comprising two generally parallel flanges, a first flange 50 and a second flange 51 arranged at a first distance d from each other forming a first slit, whereby the first slit forms the first outlet 46. The flanges are arranged generally at a right angle in relation to the longitudinal direction of the first bore 48. In this embodiment the first flange 50 is provided with preferably symmetrically arranged optional horizontal grooves 53 and optional inclined grooves 53' (Fig. 5) in order to form distribution ducts for directing the rinse water in given directions over the interior surface 2 of the sanitary unit 1. The grooves provide a more concentrated and stronger flow or rinse water, as indicated by the bigger arrows. The purpose of the horizontal grooves 53 shown in Fig. 5 is to distribute the rinse water along the shelf 6 provided along the interior surface 2 of the sanitary unit 1. The purpose of the downward directed inclined grooves 53' is to secure a rinsing of the interior side of the back wall portion 5 and the interior side wall portions 8 of the sanitary unit 1. The smaller arrows indicate that rinse water is spread in a more general manner. It is clear that this may be modified according to the form of the interior surface of the sanitary unit. The distribution and number of the optional grooves may vary.
The first inlet 44 and the first bore 45 are arranged in an adapter means 54 for connection to a source of rinse water, i.e. the rinse water supply 107 through the rinse water valve 108. In the embodiment shown the adapter means simply comprises a tube formed extension of the first bore 45.
The second end 43 of the rinse water nozzle 4 further comprises a third flange 52 at the second opening 49 at end of the second bore 48. The third flange 52, which functions as a shield (described more in detail below), is arranged gen- erally at a right angle in relation to the longitudinal direction of the second bore 48 (and the first bore 45), and in parallel with the first flange 50 and the second flange 51. The second flange 51 and the third flange 52 are at a second distance D from each other forming a second slit, whereby the second slit forms the second opening 49. The third flange 52 shields or covers the second opening 49 leading into the second bore 48 in order to prevent any undesired substances from entering (indicated by black arrow in Fig. 4) the thus formed aeration means from the inside
of the sanitary unit 1. In practice this could be splashing of rinse water and sewage. The second bore 48 and the second opening 49 are also shown in Fig. 6, showing section B-B of Fig. 3.
The rinse water nozzle 4 comprising a two bore arrangement for the dis- tribution of rinse water on one hand and for providing an aeration means on the other hand may be formed in one piece, e.g. of a plastics material. This provides a very simple solution in view of manufacture, secure performance, possible maintenance and installation.
Fig. 7 shows a perspective view of the rinse water nozzle 4. The refer- ence numerals in this figure correspond to those in the other figures discussed above.
In order to install the rinse water nozzle 4 in the sanitary unit 1 , the back wall portion 5 is provided with a bore for receiving the rinse water nozzle 4. The first end of 42 the rinse water nozzle 4 may extend outside of the sanitary unit in order to connect the first adapter means 54 to a source of rinse water, e.g. a rinse water hose or tube in connection with the rinse water supply 107. The first adapter means 54 may be provided with and edge 55 in order to secure such a connection. The second end 43 of the rinse water nozzle 4 is then situated on the interior side of the back wall portion 5 for distributing rinse water into the sanitary unit and aer- ating the same. The perspective view of the rinse water nozzle 4 in Fig. 7 also shows an embodiment where the first opening 47 and the second bore 48 are formed in a tube formed second adapter means 56. In order to provide an easy and secure installation in the bore of the back wall portion 5 of the sanitary unit 1 , the second adapter means 56 is provided with slits 57 for flexibility and edges 58 for fastening. An installation like this is basically known to a person skilled in the art and is therefore not described more in detail in this connection.
The drawings and the description related thereto are only intended for clarification of the basic idea of the invention. The invention may vary in further detail within the scope of the ensuing claims.
