EP3357384B1 - A shower floor - Google Patents

Description

The present invention relates on the one hand to the floor of a shower and on the other hand to a building with a bathroom, the floor of a shower being arranged in the region of a wall.

Showers in various designs are well known from the prior art. The most widespread use of a shower tray is as the bottom of a shower, a siphon being flanged onto the shower tray by means of a screw connection. The shower tray has a drain opening, the siphon being flanged to the edge of the drain opening. The siphon itself points one from below into the drain opening for connection to the shower tray Siphon insert protruding from the drain opening with an annular seal, a lock washer being screwable from above onto the bottom of the shower base. The counter ring also has a seal facing the shower tray. In the assembled state of the siphon, there is an absolutely tight connection between the shower base on the one hand and the siphon on the other.

So-called tile or plate showers are also known. This is a shower where the tiled floor of the bathroom extends into the shower, for example. Here, two embodiments are known, namely a first embodiment in which a drain device is provided in the floor of the shower, with a plurality of slope levels, in particular four slope levels, being provided in the floor around the drain device. The drain device comprises a drain opening arranged in the floor and a drain device, the drain device comprising a drain sleeve with which the drain device projects up to the top of the tile mirror. On the top of the sleeve there is a lid, which is provided with individual grooves to ensure that water can flow into the sleeve. The sleeve is at the bottom of a drain body and is sealed horizontally at the top with a silicone joint against the tile mirror. In order to prevent the water from penetrating directly into the substructure of the floor when the silicone joint is damaged, it is provided that the upper collar of the drain body has a sleeve made of a water-impermeable film, which is made of screed, hard foam building boards on the surrounding substructure or similar is glued below the tile mirror. The waterproof cuff has a size of about 30 x 30 cm, which means that the cuff only extends over a small part of the floor area of the shower. The rest of the floor of the shower is covered with a waterproof coating that is attached to the cuff. The seal described above is secure against moisture penetrating, for example, through the joints of the tile mirror. However, it is not intended to provide a permanent seal when water is pressed. Pressurized water occurs when, for example, the silicone joint between the tile mirror on the one hand and the drain sleeve, which holds the cover of the drain device, on the other hand, is damaged. In other words, the floor of such a shower is only partially sealed.

From the US 2008/0190048 A1 a shower base is known which has a multiplicity of channels with a width of approximately 2 mm and a depth of approximately 0.5 mm.

In addition, there are tile or plate showers that have a so-called line drain. A linear drainage is understood to mean a linear drainage slot which extends over a substantial part of the width of the shower, the water being absorbed by a rectangular-shaped gutter shell made of stainless steel over the entire length of the drainage slot and through a siphon arranged on the bowl into the sewer is directed.

The gutter shell with the inserted slotted top part of such a line drain rests on a table that has height-adjustable feet. The problem here is that the table with the height-adjustable feet stands on the raw concrete floor. This means that the table must be set to the intended height before the screed is poured. After the screed has been applied, the height of the channel can no longer be changed. In many cases, this is not without its problems, especially if, for example, after the screed has been applied, it turns out that the screed is wavy, so that a leveling layer must still be applied to the screed before the tile mirror or, generally speaking, the floor panels of the shower are applied will. Is too here, similar to the point sequence of a tile or plate shower described above, it is provided that the channel is only sealed against the tile mirror by a silicone joint. Another problem with such a line process is that such a shower also has at least two, sometimes even up to five slope levels with a large number of technically complex, optically unattractive and technically problematic dividing joints and fitting panels of the top covering.

From the DE 10 2007 056 472 A1 a shower plate is known which has a curved top and a drain device with a sloping circumferential channel, the channel having a drain opening at the lowest point. Through the gutter, all water should be drained into the drain opening when showering. The shower plate can be made of natural stone; However, such a natural stone shower panel must be of considerable strength if it is assumed that the channel has a continuous gradient of approximately 2%, which is common in the sanitary area. Such a shower plate is therefore expensive and can only be handled to a limited extent due to its weight. In addition, due to the depth of the gutter, it is difficult to clean.

From the US 3,942,199 a shower tray is known which has a drain in the middle, the bottom of the shower tray being designed to slope towards the drain. This means that the bottom of the shower tray has a slope at every point on the bottom of the shower tray. Furthermore, a wide variety of floor designs are known from the above US document in order to provide a non-slip surface. For example, a floor design is known, consisting of an arrangement of square elevations, between which channels run in the longitudinal and transverse directions.

The object on which the invention is based is now to provide, in the case of a floor of a shower of the type mentioned, a drain device which is easy to clean and which has only a low floor height.

To achieve the object, it is proposed according to the invention in the case of a floor of a shower that the floor comprises at least one floor plate made of natural stone, artificial stone, porcelain stoneware or ceramic and the floor has at least one drain device, the drain device comprising a drain opening arranged in the base plate, the Bottom plate has a single groove or no more than two groove sections which open into the drain opening, the groove or the groove sections having an arcuate cross section and being kept flat, the groove or the groove sections are polished and without a slope have a uniform depth over the length of approximately 0.6-1.0 mm. In summary, this means that if the groove or the groove sections are arcuate in cross-section with a shallow depth of only about 1 mm, and advantageously the groove or the groove sections are polished, it follows that, in particular, those machined into the base plate milled groove sections or a groove that has no slope to the drain opening, due to the capillary action, the water film that is formed directly in the area of the groove is pulled off. This means that in the area of the groove and here also in the area of the drain device, the shower base dries of its own accord within a very short time, thus making cleaning considerably easier.

The use of a groove without a slope also allows the use of tiles with a thickness of 10 mm or less as the base plate. Due to the low height of the groove, easy cleaning is also possible without any problems.

Advantageous features and refinements of the invention result from the subclaims.

It has already been shown that the base plate has at least one groove which opens into the drain opening. The groove is advantageously located at the lowest point of the shower base, which is also advantageously located directly on a wall of the shower, so that the groove can be positioned directly in front of the wall. This means that the water hitting the shower floor is conveyed through the slope of the shower floor in the direction of the groove, from where it is also fed through the groove to the sewer through the drain device. That means, for example, the shower base made of tiles or floor slabs only has a single slope level. Deepest The groove is at the point of the slope. The drain device can be arranged, for example, in the middle of the wall directly in front of the wall, so that the groove on both sides of the drain device is divided into two groove sections, each of which opens into the drain opening of the drain device. It is clear from this that the groove sections are advantageously arranged along a straight line in the base plate.

It has already been stated that the groove or the groove sections should be located directly on the wall of a shower. In this respect, it is provided that the groove or the groove sections are worked into the base plate directly in front of the wall, in particular are milled.
The size of the floor plate can correspond to the area of the floor of the shower; However, there is also the possibility of using a plurality of floor slabs or tiles, the individual floor slabs or tiles being provided with a corresponding groove or a corresponding groove section, in which case a groove with individual grooves extending essentially over the width or length of the shower groove sections worked into the base plates results. Here, the tile separating joints made of cement, epoxy resin, silicone or the like between the individual groove sections can be adapted to the shape and the course of the groove profile by hand washing out or pulling off with a suitably shaped profile tool.

According to a further advantageous feature of the invention, it is provided that the drain device comprises a cover. The lid can rest on the drain opening or on the siphon at a radial distance from the base plate. The cover can be flush with the surrounding tile mirror at a radial distance from the base plate or it can also protrude in height and slightly overlap the drain opening. The optical outer is advantageous in the first case Appearance and in the latter case the lower overall height, as well as the lower manufacturing costs, since the drain body can be flanged directly to the plate and does not have to be set lower, for example by means of a spacer element in the connection area, which is additionally attached under the tile in industrial production. However, there is also the possibility of having the cover connected flush with the surrounding tile mirror or the base plate directly to the edge or collar of an outlet opening in the base plate in the region of the groove openings, which is very advantageous in terms of the external appearance. In the case of thin floor plates or tiles, the drain body can be flanged to an additional spacer element under the tile, which is industrially firmly attached under the floor plate. If necessary, the cover itself can also have additional openings in order to increase the water drainage capacity at high water flow rates. In all cases, the covers are detachably connected to the drain body or the base plate to allow access to all relevant areas and components within the siphon drain body for inspection and cleaning.

With regard to the design of the drain opening, according to a further advantageous feature of the invention, it is provided, for example, to mill an edge or collar circumferentially around the drain opening in order for the siphon or parts of the siphon to rest or rest on it. The milled edge creates a flat contact surface for the upper and lower seals of the siphon. It is clear from this that, in order to ensure complete drainage in the area of the drain device, the edge around the drain opening is lower than the groove or the groove sections. As already explained, an edge for receiving the siphon or parts of the siphon can be provided with thin base plates or tiles, a spacer element made of a suitable material, for. B. is made of ABS plastic. The Spacer is then firmly, watertight and non-detachably attached to the underside of the base plate in the industrial manufacture of the base plate, e.g. B. with a suitable adhesive connection.

The drain device advantageously has a drain opening with a siphon, the siphon in the area of the drain opening on the at least one floor slab or floor tile, e.g. B. made of natural / artificial stone, porcelain stoneware, ceramics or the like, arranged watertight, in particular flanged and further screwed here. The connection between the siphon on the one hand and the base plate on the other hand can be made indirectly by, for example, a spacer element discussed later or directly on the base plate. This means that a drain device is arranged on a base plate of a tile or plate shower, which ensures absolute tightness against water. For this purpose, a siphon is used, as used for example in a known shower tray, and as described at the beginning. The siphon essentially consists of two parts, namely a drain body, which is attached from below to the base plate with a seal at the drain opening, and a lock ring, which is screwed to the drain body with a seal lying on the base plate. An advantage of such a siphon known per se is the low installation height and in particular also the simple, standardized assembly. The base plates can be completely prefabricated industrially, so that they only have to be placed on the flange of the drain body during assembly and screwed through the lock ring. It is the same known simple assembly as with commercially available shower trays. The base plate lies on the screed or another sub-floor, with the sub-floor, e.g. B. from screed, hard foam panels or the like, is recessed accordingly. The advantage of a shower base with only one base plate is that only one slope level without additional, disadvantageous dividing joints and fitting plates must be formed.

The invention also relates to a building with a bathroom, the bathroom comprising at least one wall, a shower being arranged in the region of the wall, the shower being characterized by a floor according to one or more of claims 1 to 10.

In this context, it is provided in particular that the groove or the groove sections are arranged in the base plate in such a way that the edge of the groove or the groove sections essentially closes with the tiles of the wall of the shower. From this it is clear that the edge of the groove lies approximately in one plane to the wall of the shower. In this respect, the groove and the groove sections advantageously run parallel to the wall. The bottom plate itself, which preferably extends over the entire surface of the floor of the shower, has a slope in the direction of the groove or the groove sections. This can be accomplished, for example, in that the base plate is arranged on the sub-floor made of screed, hard foam building boards or the like in a slightly inclined manner, or in that the sub-floor itself is wedge-shaped.

The invention also relates to the use of a siphon as part of a drain device for flange mounting on a base plate of a shower.

Both Figures 1a , 1b , 2a , 2 B , 3a , 3b and 4a , 4b the same parts are provided with the same reference numerals. The floor 1 of the shower, the shower device of which, for example, the shower, is not shown, comprises the base plate 3, the base plate 3 either having a size which can essentially correspond to the size of the base of the shower or being part of a base with a large number of floor slabs. The base plate 3 is glued to the screed 5 in the adhesive bed 7; the screed itself as a sub-floor is arranged on the raw concrete floor 9. The bottom plate 3 is supported at one end directly on the wall designated by 11 with the wall tiles 12. In the transition from the Tile 12 to the base plate 3, a silicone joint 13 is provided. A sealing sleeve 31 is arranged in the adhesive bed 7, which has a size of approximately 30 × 30 cm and extends in the area of the siphon 25. Otherwise, the bottom of the shower is provided with a moisture-impermeable coating to form a further seal 33. Both Figures 1a , 1b and 2a , 2 B the base plate is doubled, at least in the area of the siphon 25. Such a procedure may be necessary for static reasons if the base plate has only a small thickness in the area of the siphon, as shown, B. is the case with tiles. Regardless of this, a certain height of the water column above the siphon should be ensured so that the siphon achieves sufficient swallowing capacity. Irrespective of static reasons, this can also be achieved in that the cover protrudes beyond the base plate 3, as can be seen in FIGS Figures 3a , 3b with the cover designated there with 46 results. Such a projection of the cover 46 provides an adequate water column between the siphon and the underside of the cover.

In order to provide such a sufficient water column even with thin base plates, a spacer 50 can be provided between the underside of the base plate and the siphon. B. can be made of plastic (e.g. ABS) ( Fig. 4a , 4b and Fig. 5 ).

The spacer element 50 has a collar 52 for attachment to the base plate 3 and a collar 54 for connection to the drain body of the siphon 25 ( Fig. 4a , Fig. 4b , Fig. 5 ). The collar 52 and the collar 54 are connected by an annular body 56, the height of which is selected such that a sufficient water column can form above the siphon, even if the cover 58 is flush with the top of the base plate 3 in the case of a thin base plate. The spacer 50 can be part of the base plate in the manufacture with the base plate be glued so that it is firmly connected to the base plate. In other words, the siphon can be indirectly connected to the base plate by the spacer element or can be flanged directly to the base plate.

Immediately following the wall tile, the base plate 3 has a groove, denoted overall by 15, which finally opens into the drain opening 17 of the drain device 19. The groove can also be called a groove. In detail, the groove 15 comprises two groove sections 15a and 15b, each of which opens into the groove drain 21 of the drain device 19 with a slight slope. The groove drain 21 opens into the drain opening 17. Here it is provided that the groove sections 15a and 15b lie higher than the groove drain 21, the groove drain 21 in turn lies higher than the edge 23 which extends around the drain opening 17. In the region of the edge 23, which extends around the drain opening, the siphon, designated as a whole by 25, is arranged.

It has been found in tests with regard to the formation of the groove or the groove sections that an arc-shaped milled groove or arc-shaped milled groove sections, the groove or the groove sections being polished, and a depth of approximately 0. 6 - 1.0 mm, i.e. do not have a slope, ensure that due to the capillary action the water film dries not only in the groove, but also around the groove within a very short time. In particular, this also prevents the silicone joint from becoming unsightly over time due to mold formation in the transition from the floor slab to the wall. Thus, the groove or the groove sections can be kept flat, which not only facilitates cleaning, but also manufacture in relation to the milling process. A flat groove is also preferred for optical reasons.

The siphon 25 comprises a drain body 27 and a lock ring 29, both the drain body 27 and the lock ring 29 having a seal 30, 32 ( Fig. 6 ), which can be firmly connected to one another by an annular web (not shown). The seal 32 of the counter ring is located on the top of the edge 23, whereas the seal 30 of the drain body 27 is arranged adjacent to the underside of the base plate in the region of the edge. The lock ring 29 also has two screws 34, which are arranged opposite one another on the lock ring and which serve to connect the lock ring to the drain body 27 through the base plate in the region of the edge 23.

In addition, the screws 34 serve to receive the covers 36 and 46, the cover 36 according to Fig. 1b has a radial distance 37 to the base plate 3. The radial distance 37 serves to discharge the water hitting the base plate.

The siphon 25 is, as has already been stated, below the base plate 3 within the screed 5. In order to be able to accommodate the drain body 27 of the siphon 25 in the screed 5, the screed 5 has a recess 38 at the corresponding point. The drain body 27 also has a drainage pipe 40 for connection to the sewage pipe (not shown).

The in the Figures 2a and 2 B shown drain device 19 differs from that according to the Figures 1a and 1b in that here the cover 42 extends on the drain device 19 to the groove 15. The groove drain 21 according to Fig. 2a is so deep that it extends below the cover 42 into the drain opening 17. The lid can optionally, in order to allow the water to drain directly from the base plate 3, additionally several water passage openings 44 in the form of slots to increase the water drainage capacity. Otherwise, the cover 42 lies directly against the base plate 3. Such also arises in relation to the cover 58 according to FIGS Figures 4a , 4b , which sits directly on the edge 23 of the base plate 3 and extends to the groove sections 15a, 15b. Through the groove outlet 21, the groove sections 15a, 15b are connected to the outlet opening 17 under the cover.

Fig. 7 schematically shows a top view of the bottom of a shower, the arrows indicating the water flow. The shower base has a single slope in the direction of the groove. The groove already ensures optimal water drainage from the shower floor into the narrow drain opening during the shower process. This effect is achieved by the vectorial superimposition of the orthogonal flow from the slope plane of the floor against the rising wall with the cross flow in the area of the groove. As a result of this coupling or superimposition of the intersecting flows, very advantageous laminar radial flows or streamlines occur in the drain in the area of the groove, as a result of which this can be designed to be optically very small with maximum absorption capacity.
