DESCRIPTION

Shower tray with integrated siphon Technical field

The present invention relates to a siphon assembly. More particularly, the invention relates to a shower tray with said siphon integrated in the plate.

Context of the invention

In order to allow the water in a shower to drain properly, it is usual to use a shower tray, which is generally a substantially flat surface placed under the shower, so that the shower water is collected thanks to an inclined plane that directs the water to a wastewater evacuation system, which may be connected by a hole in the plate.

If the shower tray is equipped with an integrated siphon, the latter can easily be fixed to a traditional wastewater evacuation system, which simplifies installation. However, the integration of the siphon under the shower tray increases to the height of the latter, the siphon assembly being often installed directly below the drain hole, as described in EP 1 098 041, EP 1 518 969 and DE 101 46 812. EP 1 098 041 describes a shower tray according to the preamble of claim 1.

Another solution is to install the siphon on the side of the shower tray and thus allow the connection of the plate through a drain hole made on the side of the plate. However, a horizontal connection to the wastewater evacuation system is not desirable, since this type of connection is more susceptible to leaks than a vertical connection. In addition, it can be difficult to make a sufficient seal of the siphon when the drain hole is located on the side of the plate, which can lead to the emanation of odors that come from the wastewater evacuation system and exit through the drain hole.

In US 4 922 948, grilles are also described.

Therefore, it would be advantageous to have an improved shower tray and, in particular, it would be advantageous to have a shower tray that is easily installed, which has a good value for money and is pleasant to use.

Summary

Accordingly, the present invention has the purpose, preferably, to reduce, mitigate or suppress one or more of the drawbacks and gaps of the technique identified above, either individually, either by any combination and allows solving at least the inconveniences mentioned above thanks to a shower tray with integrated siphon.

According to the invention, a shower tray with integrated siphon is provided. Said shower tray comprises a plate part and a siphon-forming structure that includes an outlet orifice fixed to a waste water evacuation tube, arranged in a first piece of continuous material with the plate part inclined towards the structure that forms siphon, further comprising a cover in a second piece of material, separated from the first piece of material, said cover comprising a cover plate and a cylindrical cover part, which extends substantially perpendicularly from the plate of coating. The siphon-forming structure forms a space where the water flowing from the platter part into the siphon-forming structure is seized before leaving the siphon-forming structure by the wastewater evacuation tube and in which the cylindrical part The coating, when applied to the wastewater evacuation tube, protrudes into the siphon-forming structure, so that it is immersed in the seized water without being trapped with the surface of the siphoning structure and the cylindrical part of the coating comprises a grid-forming structure, fixed along the end of the element that projects in a direction substantially perpendicular to the cylindrical covering part. The invention consists in facilitating the cleaning of the siphon by simple removal of the lid by means of a grid-forming structure to filter the evacuation water, such that the filter is part of the lid. It can also present less risk than existing solutions and is more profitable and greener.

The wastewater evacuation tube may be fixed to the siphon-forming structure, so that the direction of the diameter of the wastewater evacuation tube, at the point of attachment with the siphon-forming structure, is substantially horizontally aligned .

The advantage, in this document, is that the connection may be less subject to leakage.

The siphon-forming structure of the siphon may comprise a recess in which the wastewater evacuation tube can be placed.

The advantage, in this document, is that the shower tray can be lower, since the water tube does not need to extend under the siphon.

In one of the embodiments, the waste water drain pipe is in L.

This has an advantage, since the water tube can then be connected to the siphon-forming structure, so that the direction of the diameter of the wastewater evacuation tube, at the point of attachment with the siphon-forming structure, is aligned substantially horizontally and extend simultaneously from the side of the siphon, for example, through the recess.

The edge of the outlet orifice of the siphon-forming structure of the siphon can form a first ridge and the wastewater evacuation tube may comprise a second crest, which extends around the tube along the perimeter of the tube, so that A part that forms a joint can be found between the first crest and the second crest, which, in this way, ensures the tightness of the junction between the siphon-forming structure and the wastewater evacuation tube.

The advantage, in this document, is that a stronger pressure can then be exerted on the joint-forming part, which makes the connection between the siphon-forming structure and the wastewater evacuation tube less subject to leakage.

In one embodiment, the shower tray further comprises a plug, inserted in the wastewater evacuation tube and which is trapped with the first ridge.

Said cap may include an external threading part and the waste water drain pipe, at the point of attachment with the siphon-forming structure, may include an internal threading part.

This system is advantageous, since it facilitates the connection between the wastewater evacuation tube and the siphon-forming structure.

In one embodiment, the lowest point of the cylindrical part of the shower tray is at a vertical distance of at least 50 mm from the highest point of the internal cylindrical part, when the lid is placed on the siphon-forming structure .

The advantage, in this document, is that the siphon respects European standards.

This system is advantageous, since the grid-forming structure can serve as a filter for particles that could otherwise plug the wastewater drain pipe. Since the filter is part of the lid, it is easy to clean by removing the lid.

The present invention has the advantage, as a whole, with respect to the prior art, of providing a shower tray with integrated siphon. The latter is profitable and ecological. In addition, the final product needs less space for installation and is easier to install and use.

These embodiments are described in order to make the present description complete and exhaustive and fully translate the scope of the invention for the person skilled in the art. These embodiments do not limit the invention in any case, the latter being limited only by the appended claims. In addition, the terminology used in the detailed description of the particular embodiments illustrated in the accompanying drawings is not considered to constitute a limit to the invention.

The following description is about an embodiment of the present invention that can be applied to a shower tray that includes a substantially cylindrical siphon assembly positioned in the vicinity of one side of the surface of the plate. However, as the person skilled in the art knows well, the siphon assembly can have various types of appropriate geometric shapes and can also be placed in different places under the plate.

In an embodiment according to Figure 1 which is not part of the invention, a shower tray with integrated siphon 10 is provided. The shower tray comprises a plate part 100, which is formed by a single piece. This system is advantageous, since it limits the risk of leaks. The plate part 100 comprises a plate surface 110, which is inclined, so that the water that falls on the plate surface 110 flows in an evacuation channel 120, which is also comprised in the plate part 100. The plate portion 100 further comprises a structure that forms a siphon 130, which is located in the evacuation channel 120, so that water flows from the evacuation channel and descends into the structure that forms a siphon 130. The structure that forms siphon 130 comprises an external cylindrical part of large dimension 131 and an internal cylindrical part of small dimension 132. The internal cylindrical part 132 is placed inside the external cylindrical part 131 and the bases of the two cylindrical parts 131, 132 which are furthest from the evacuation channel 120 are fixed to each other by a tight bottom 133. The base of the outer cylindrical part 131, which is not fixed to the inner cylindrical part, is fixed it gives the evacuation channel 120 and, in this way, connects the siphon-forming structure 130 to the plate part 100. Thus, as we see clearly in Figure 1, the two cylindrical parts 131, 132 and the watertight bottom 133 are comprised in the shower tray 100, as a single integrated unit that extends from the evacuation channel 120 in a direction substantially perpendicular to the plate surface 110 and, thus, forms a continuous plate with integrated siphon 10 .

As the person skilled in the art will appreciate, the plate with integrated siphon 10 can be made from a molded resin stone, solid surface materials, ceramic, concrete etc.

The plate with integrated siphon 10 can be modeled from a single piece of plastic material by heating, then by pressing. The shower tray 130 and the siphon 131 can also be produced in two different parts that are immovably assembled together by welding or gluing to obtain the complete shower tray with integrated siphon.

The internal cylindrical part 132 is slightly shorter than the external cylindrical part 131. As the cylindrical parts 131, 132 are fixed by the sealed bottom 133 at a level substantially identical to a first end, the second end of the relatively more cylindrical internal part cut 132 is therefore not at the same level as the second end of the relatively longer external cylindrical part 131. When water flows from the shower tray 100, in the drain channel 120 and then in the part external cylindrical 131, therefore, is retained in the space created by the walls of the external cylindrical part 131, the internal cylindrical part 132 and the sealed bottom 133. However, when the water level reaches the top of the internal cylindrical part 132, the water flows into the internal cylindrical part 132, which, thus, leaves the siphon-forming structure 130. If the top part of the internal cylindrical part 132 e It is fixed to a wastewater evacuation tube 150, which can be found inside the internal cylindrical part 132, the water then deflects, and flows into the wastewater evacuation system.

The depth of the joint of the siphon-forming structure 130 is therefore identical to the height of the internal cylindrical part 132.

As one skilled in the art will appreciate, the exact dimensions of the different parts of the integrated siphon 10 are variable. However, according to a non-limiting example, the internal cylindrical part 132 can measure 56 mm in length and can have a diameter of 92 mm. The outer cylindrical part 131 can measure 61 mm in length and can have a diameter of 156 mm. The shower tray with integrated siphon 10 further comprises a cover 140 which, in service, is placed on the siphon-forming structure 130. The cover 140 comprises a cover plate 141 which, in service, is substantially parallel to the shower tray. shower and a cylindrical cover part 142, which is fixed to the cover plate substantially perpendicularly.

Preferably, the cover plate 141 has the same shape as the evacuation channel 120, so that in service, it fits into the evacuation channel 120. We see it in Figure 5, which is a top view in perspective of the plate shower with integrated siphon 10. The cylindrical cover part 142 is fixed to the cover plate 141, so that in service, it fits between the external cylindrical part 131 and the internal cylindrical part 132. Thus, the cylindrical part of covering 142 extends in the siphon-forming structure 130, in the space created by the walls of the outer cylindrical part 131, the inner cylindrical part 132 and the sealed bottom 133. Now, the cylindrical covering part 142 is shorter than the outer cylindrical part 131.

Therefore, the cylindrical covering part 142 will never extend into the siphon-forming structure 130 so that it touches the sealed bottom 133. In service, this system allows water to flow without hindrance from the shower tray 100 to the interior of the internal cylindrical part 132, as we have explained above. As the cover 140, in service, is placed on the siphon-forming structure 130 and as the cylindrical covering part 142 extends in the siphon-forming structure 130, which in service is filled with water, the cover 140 completes the joint of the siphon, as we can see in figure 2, which is a perspective sectional view of the shower tray with integrated siphon 10.

In one embodiment, the lowest point of the cylindrical part 142 and the highest point of the internal cylindrical part 132 are placed at a vertical distance of 50 mm from each other, so that a siphon measuring 50 is created mm height

This system is advantageous, since the siphon is compliant, then, with European standards.

Figure 1 is an exploded view of the shower tray with integrated siphon 10 seen from above and Figure 3 is an exploded view of the shower tray with integrated siphon 10 seen from below.

The fact that the lid 140 is part of the siphon is advantageous, since this requires fewer separate parts, which lowers the manufacturing cost.

The cover 140 can be made from the same material as the shower tray 100, but it can also be made of a different material.

As the person skilled in the art will appreciate, the cover can be made of any molded or pressed material, such as a resin stone, a solid surface, a ceramic, a plastic material or a metal. The cover 140 can be made with a single and homogeneous piece. However, the cover 140 can also be made in two parts which are then assembled, for example, welded or glued to each other in an immovable and sealed manner.

The siphon-forming structure 130 can be connected to a wastewater evacuation tube 150, as shown in Figures 1 and 2 that do not form parts of the invention. The exit orifice of the siphon-forming structure 130 forms a first ridge 134 and the wastewater evacuation tube 150 comprises a second ridge 151, which extends around the tube along the perimeter of the tube. The waste water drain pipe 150 is placed inside the inner cylindrical part 132 and is connected to the inner cylindrical part 132 at the top of the latter 132. The connection is made thanks to a plug 160 and a part which forms gasket 170. The part that forms gasket 170 can be a simple o-ring or flat ring of a dimension that allows it, in service, to prevent water leakage. The joint-forming part is placed between the first ridge 134 of the siphon-forming structure 130 and the second ridge 151 of the wastewater evacuation tube 150. The joint-forming part 170 is held in place between the first ridge 134 of the siphon-forming structure 130 and the second ridge 151 by the plug 160, which is positioned so that it extends into the wastewater drain pipe 150, so that the wastewater drain pipe 150 is carefully connected to the internal cylindrical part 132. In one embodiment, there is an external thread around the plug 160 and an internal thread in the waste water drain pipe 150, so that the plug 160 can be removably screwed into the drain pipe of wastewater 150 and, once solidly fixed, create a tight seal around the joint-forming part 170.

Preferably, but this is not mandatory, as shown in Figure 3, which is not part of the invention, the siphon-forming structure 130 may include a recess 180 in which the waste water evacuation tube 150 is placed, which allows that the wastewater evacuation tube 150 extends from the siphoning structure 130 in a direction substantially perpendicular to the diameter of the cylindrical parts 131, 132, 142. The wastewater evacuation tube 150 may be in L, so that it is connected to the inner cylindrical part 132 at the top of the latter 132, substantially parallel to the diameter of the inner cylindrical part, extends through the inner part of the inner cylindrical part 132, then bends, so that it can deviate through the recess in a direction substantially perpendicular to the diameter of the cylindrical parts 131, 132, 142. We see it in Figure 2 and in Figure 6, qu e is a bottom perspective view of the shower tray with integrated siphon 10.

This system is advantageous, since it allows the structure that forms a siphon 130 to be smaller, which then generates a shower tray with integrated siphon 10 lower. At the same time, the connection between the shower tray with integrated siphon 10 and the wastewater evacuation system is substantially horizontal and thus presents less risk of leakage than a substantially vertical connection.

In one embodiment (not shown), the wastewater evacuation tube 150 is rectilinear, which means that it extends vertically from the cylindrical part 132.

In an embodiment of the invention of Figure 4, the cylindrical covering part 142 is provided with a grid-forming structure 400, fixed along the end of the cylindrical covering part 142 that extends into the forming structure. siphon 130. The grid-forming structure 400 is fixed on the perimeter of the cylindrical covering part 142, substantially cylindrical perpendicularly covering the diameter 5 of the cylindrical covering part 142. The width of the grid forming structure 400 is adapted for the distance between the external cylindrical part 131 and the internal cylindrical part 132. Thus, in service, when the cylindrical covering part 142 is placed in the siphon-forming structure 130, the grid-forming structure 400 functions as a trap for hair and other particles, while allowing water to pass through the rack.

10

This system is advantageous, due to the fact that it constitutes a simple means to separate the hair and other particles from the water and that it is easy to clean it, by simply lifting the lid 140.
