Description

Narrow drain.

The invention relates to a drain according to the preamble of claim 1. Such a drain is for example known from WO 2007/004863. A siphon is used as trap for bad odors in drains such as sinks, bathrooms and showers. A siphon closes the access to the sewer pipe by forming a layer of water. Another example of a drainage is known from WO 01/073231.

Numerous siphons are known in many ways and variations The best known form is the so-called neck of swan. This consists of a normally round tube, which has a first part directed downwards which then bends towards a part directed upwards and then bends once more towards a part directed downwards. Because of this form the water it will always remain in the first part directed downwards and in the part directed upwards, whereby the connection to the sewer remains closed. Such swan necks are still frequently used under sinks.

For showers, a different siphon variant is known. This is due in particular to the limited overall depth of the whole as a result of the thickness of the soil. Such a siphon consists of a cylindrical receptacle in which a discharge tube protrudes centrally. An inverted receptacle is then placed on this discharge tube. Here the closing is also done when a certain amount of
Water.

In all siphons it is important that through a sufficient amount of water can be evacuated from the siphon. By therefore, the passage surface must have a minimum area to allow a correct and fast discharge of water.

Existing siphons have the disadvantage that either its total depth is considerable, as is the case in a gooseneck, or the relationship width-length of the siphon is substantially equal to 1, which occupies a considerable amount of space.

It is now an object of the invention to provide a drain that can be given a narrow shape, remaining the total depth limited.

This object is achieved with a drain according to the claim 1.

A narrow and elongated siphon is obtained ensuring an elongated incoming flow opening and arranging the second chamber substantially in the longitudinal direction of the Elongated incoming flow opening. In this way it is possible keep the visible part of a drain narrow, so that the drain disturbs as little as possible the ground on which it is installed.

In addition, the area of the useful section of the passage opening and outgoing flow opening is substantially equal to the area of the opening passage section of incoming flow. This ensures that the water that enters through the incoming flow opening is not blocked or slowed down and a rapid discharge of water is possible.

In another embodiment of the drain according to the invention, the outflow flow opening is arranged in longitudinal direction of the elongate incoming flow opening, of way adjacent to this incoming flow opening. In this way the narrowest siphon possible is also possible.

In yet another embodiment, the second camera has a cross section, at least along the distance between the passage opening and the outflow flow opening, which is at least substantially equal to the area of the opening passage section of incoming flow.

In a further embodiment of the drain of according to the invention, the relationship between the dimensions Main of the elongated incoming flow opening is at least 1: 2, preferably 1: 6.

In a further embodiment, the first camera of the drain is preferably formed by at least a part of the housing such that the discharge opening is connected to the first camera only through the second camera.

In another embodiment of the drain according to the invention, the outflow flow opening of the siphon is connected through a channel to the discharge opening of the accommodation.

A further preferred embodiment of the drain according to the invention comprises a gutter that guides liquid which must be evacuated to the incoming flow opening of the First camera

Due to the narrow realization of the siphon is it is also possible to provide the drain in a narrow way, and you can arrange an elongated gutter having a minimum width. This is highly recommended when considering considerations aesthetic

Another drain, which does not agree with the invention, comprises:

-

a tubular housing;

-

a first baffle positioned obliquely in the longitudinal direction in the accommodation, where on the lower face, between the first baffle and tubular housing, a passage opening is procured with an area of the passage section substantially equal to the area of the passage section of the tubular housing;

-

second and third deflectors placed obliquely in the longitudinal direction in the housing, both sides of the first baffle, where on the upper face, between the second and third baffles and tubular housing, is procured a passage opening with an area of the passage section substantially equal to the area of the passage section of the housing tubular.

In this drain the siphon is created by placing three baffles in the tubular housing. Openings are arranged elongated placing the different baffles obliquely in the accommodation, so that a narrow siphon is created, which is accommodated in the tubular housing. It is thus possible to arrange a siphon in an existing outlet pipe. Being the baffles located in oblique direction and thus provide passage openings elongated, the flow rate through the outlet tube is retained at less in a very high proportion.

This and other features of the invention are clarify in more detail by referring to the drawings attached.

Figure 1 shows a perspective view of a first embodiment of a drain according to the invention.

Figure 2 shows the drain according to Figure 1 In another perspective view.

Figure 3 shows a removable part of the siphon of the drain of Figure 1.

Figure 4 shows an embodiment of a drain that is not in accordance with the invention.

Figure 5 shows an embodiment of a drain that is not in accordance with the invention.

Figure 1 shows a drain 1 having a housing 2 with a discharge opening 3 arranged on the side. A flow opening is arranged on the upper side of the housing incoming 4. A gutter 5, which guides the water W towards the opening of incoming flow 4, is arranged in the housing 2.

Figure 2 shows the drain 1 according to Figure 1 in another perspective view. It is evident here that the water W that flows through the incoming flow opening 4 enters a first chamber 6 formed by a part of the housing 2 and a insert 7. The insert 7 is shown in more detail in the Figure 3. The water W flowing into the chamber 6 then arrives at a passage opening 8 that is arranged on the underside of the insert 7. As shown in Figure 1, water W enters in a second chamber 9 through this passage opening 8.

The second camera 9 is provided in the face top of an outflow opening 10 along which the water W can flow out of the second chamber 9 and thus enters the discharge opening 3. When the flow opening is elongated incoming 4, the width of the drain 1 may remain limited. To the have also been chosen the dimensions of the passage opening 8 and of the outflow flow opening 10 such that the area of the passage section of the openings is almost the same, it is ensured that a correct evacuation of the water takes place W.

The insert 7 with the second chamber 9 is removably connected to discharge opening 3 through of a flange 11. This provides the advantage that the part of the drain drain 1 can be easily cleaned.

Figures 4A and 4B show an embodiment 20 of a drain that is not in accordance with the invention. This drain 20 has a tubular housing in which a first deflector 22, a second deflector 23 and a third deflector 24. The first baffle is arranged so that there is a passage opening 25 between the tubular housing 21 and the face upper deflector 22.

Due to the oblique placement of the baffles 22, 23, 24 in the longitudinal direction of the tube 21, the passage opening 25 is elongated and therefore the area of the section of step is considerably enlarged. The second deflector 23 is arranged against the upper face of the tube 21 so that it it forms a second passage opening 26 on the underside of the deflector 23. The third deflector 24 is also disposed of such that a third passage opening 27 is formed between the upper edge of baffle 24 and tube 21.

Thus, the water flowing through the tube 21 will first pass over the first deflector 22 through the opening step 25 and thus enter a first chamber 28. Then, the water W flows under the second deflector 23 through the passage opening 26 and from here enters the second chamber 29.

Here the water passes over the third deflector 24 a through the passage opening 27, and you can go your way through of tube 21.

Due to the arrangement of the baffles 22, 23, 24, water will remain in the first chamber 28 and in the second chamber 29. This provides a closure against bad odors. The figures 5A and 5B show an embodiment 30 of a drain that is not of according to the invention. For the sake of explaining the drawing, Figures 5A and 5B show a quadrangular tube 31, although it will be evident that said tube 31 may also have a round cross section, in fact this is the most common. However, a quadrangular tube with a view to the clarity of the drawing Figure 5A shows a sectional view here. transverse as it would be seen from above, while the Figure 5B shows a cropped side view.

The tube 31 has an inlet opening 32 at along which water flows inside. In tube 31 is arranged a curved deflector 33, which rests against the face upper completely shutter and free a opening 34 on the underside. The water W flowing inside You can enter space 35 through this opening 34.

Space 35 is delimited by the first baffle 33 and a second curved baffle 36, which is supported by shutter way against the underside and provides an opening of outgoing flow 37 on the upper face. The water coming from space 35 can follow its path through the flow opening outgoing 37.

The drain 30 can be placed, for example, in an existing outlet pipe and must act in conjunction with a collection tank placed before the drain 30. This tank manifold 7 can be arranged for example under a sink and This mode can maintain the level of water needed in space 35 and in the preceding space, up to the collecting tank.

Due to the placement of the baffles 33 and 36 in a substantially V-shaped, viewed from above, the flow of water W through the inlet flow opening 34, of the space 35 and outflow opening 37 will describe a flow helical. Due to this helical flow the water will be slowed down. as little as possible by placing the baffles 33 and 36. In addition, the area of the incoming flow opening 34 and the outflow opening 37 are enlarged due to the oblique placement of the baffles 33, 36, which is higher flow possible.
