Description

DESCRIPTION

Floor of a shower

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

Showers in various designs are well known from the prior art. In this way, the use of a shower tray as the floor of a shower is more widespread, with a siphon being flanged on the shower tray by means of a screw connection. The shower tray has a drain opening, the siphon being flanged at the edge of the drain opening. The siphon itself has, for connection to the shower tray in the drain area, a siphon insert that protrudes from below into the drain opening with an annular gasket, a safety washer can be screwed onto the bottom of the drain from above. shower plate. The adjusting screw also has a gasket in front of the shower tray. In the assembled state of the siphon, there is an absolutely tight connection between the shower tray on one side and the siphon on the other.

Also known are the so-called tile or plate showers. In this case it is a shower where the bathroom tile floor extends into the shower, for example. Two production models are known, namely a first production model in which a drainage device is provided on the floor of a shower, in this respect several levels of slope, in particular four levels of slope, being provided on the floor , around the drain device. The drainage device comprises a drainage opening arranged in the floor and a drainage device, the drainage device comprising a drainage sleeve with which the drainage device projects to the top of the tile base. At the top of the sleeve is arranged a cap which is provided with individual grooves to ensure that the water can flow into the sleeve. The sleeve is inserted at the bottom into a drain body and horizontally sealed at the top against the tile plinth by means of a silicone gasket. To prevent water from penetrating directly into the subfloor when the silicone gasket is damaged, the upper collar of the drain body is provided with a sleeve made of a waterproof film, which is adhered under the subfloor tile base. surrounding made of pavement, hard foam board or similar. The waterproof film sleeve is approximately 12 "x 12" in size, which means that the sleeve only extends over a small part of the shower floor area. The rest of the shower floor is covered with a waterproof liner that is attached to the sleeve. The seal described above is safe against the penetration of moisture, for example through tile baseboard joints. However, it is not intended to provide a permanent seal when water is pressed. Pressurized water occurs when, for example, the silicone gasket between the tile base, on the one hand, and the drain hose, which holds the lid of the drain device, on the other hand, is damaged. That is, the floor of such a shower is only partially sealed.

A shower floor is known from US 2008/0190048 A1, which has a multiplicity of channels with a width of approximately 2 mm and a depth of approximately 0.5 mm.

Furthermore, there are tile or plate showers that have a so-called linear drain. A linear drain is understood to mean a linear drain slot that extends over a substantial part of the width of the shower, the water being absorbed by a rectangular shaped gutter housing made of stainless steel over the entire length of the drain slot. and conducted by a siphon arranged in the casing towards the sewer.

The gutter housing with the slotted top inserted from said linear drain rests on a table having adjustable height legs. The problem in this case is that the table with the height adjustable legs is on the rough concrete floor. This means that the table must be at the desired height before pouring the flooring. After pouring the pavement, the height of the gutter can no longer be changed. In many cases, this is not without its problems, especially if, for example, after the pavement has been poured, the pavement turns out to be corrugated, so a leveling coat must still be applied to the pavement before applying the baseboard. tiles or, generally speaking, before applying the shower floor plates. Also in this case, as in the phase development of a tile or plate shower described above, it is provided that the gutter is sealed against the tile base by means of a silicone gasket. Another problem with this linear drain is that said shower also has at least two, in some cases even up to five levels of slope with a large number of dividing joints and cover layer mounting plates that are technically complex to manufacture, being visually little attractive and difficult to maintain.

A shower plate is known from DE 102007056472 A1, which has a curved upper side and a drainage device with a circumferential gutter provided with a slope, the gutter having a drainage opening at the lowest point. Through the gutter, all the water in the drain opening should be evacuated. The shower plate can be made of natural stone; however, such a shower plate made of natural stone it should have considerable strength if the gutter is supposed to have a gradient of about 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. Also, due to the depth of the gutter, it is difficult to clean.

A shower tray is known from US patent 3,942,199, which has a drain in the middle, the floor of the shower tray being shaped with a gradient towards the drain. This means that the floor of the shower tray has a slope at each point on the floor of the shower tray. In addition, a wide variety of floor designs are known from the above US document to provide a non-slip surface. Also known, among other things, is a floor design consisting of an arrangement of square elevations, between which the channels extend in the longitudinal and transverse directions.

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

To achieve the object according to the invention it is proposed for a shower floor that the floor comprises at least one base plate made of natural stone, artificial stone, porcelain stoneware or ceramic, and that the floor has at least one drainage device , the drain device comprising a drain opening arranged in the base plate, the base plate having a single slot or no more than two groove sections leading into the drain opening, the groove or groove sections having a cross section bowed and held flat, the groove or groove sections being polished and presenting without a slope over the length a uniform depth of approx. 0.6 - 1.0 mm. In short, this means that if the groove or the groove sections are arcuate in cross section with a depth of only 1mm, and advantageously the groove or the groove sections are polished, it follows that due to the capillary action, the film of water that forms directly in the groove area is drawn through groove sections or a groove that is machined into the base plate and, in particular, does not slope towards the drain opening. In other words, in the area of the groove and in this case also in the area of the drain device, the shower floor dries very quickly automatically by itself, which makes cleaning much 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 improvements of the invention result from the dependent claims.

It has already been shown that the base plate has at least one groove leading into the drain opening. The groove is advantageously located at the lowest point of the shower floor, which is also advantageously located directly in a shower wall, so that the groove can be positioned directly in front of the wall. This means that the water hitting the shower floor is carried across the slope of the shower floor in the direction of the groove, from where it is also carried through the groove to the sewer via the drain device. . That means, for example, that the shower floor made of tiles or floor plates only has a single slope. The groove is at the lowest point of the slope. The drain device can, for example, be arranged in the middle relative to 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 At the drain opening of the drain device, it is clear from here that the groove sections are advantageously arranged along a straight line on the base plate.

It has already been said that the slot or sections of the slot should be located directly on the wall of a shower. In this sense, provision is made for the slot or slot sections to be integrated into the base plate directly in front of the wall, in particular by milling. The size of the floor plate can correspond to the area of the shower floor; however, there is also the possibility of using a plurality of floor plates or tiles, the individual floor plates or tiles being provided with a corresponding groove or a corresponding groove section, then producing in total a width-extending groove or shower length with individual slot sections built into the base plates. In this case, tile separation joints made of cement, epoxy, silicone or the like between the individual groove sections can be adapted to the shape and course of the groove profile by manual washing or by removing with a profile tool. appropriate form.

According to a further advantageous characteristic of the invention, it is provided that the drain device comprises a cover. The cap 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 base or at a radial distance from the base plate, it can also protrude in height and slightly perimeter overlap the drain opening. Advantageous in the former case is the visual appearance and in the latter case the lower total 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 adjusted with greater depth, for example by means of a firmly attached spacer element in the connection area additionally under the tile during industrial production. However, there is also the possibility of having the lid flush with the surrounding tile base or base plate directly to the edge or collar of a drain opening in the base plate in the area of the slot openings, which it is very advantageous in terms of external appearance. In the case of base plates or thin floor tiles, the drain body can be clamped under the tiles to an additional spacer element that is industrially fixed under the base plate. If necessary, the lid can also have additional openings to increase the water drainage capacity in case of high water flows. In all cases, the covers are removably connected to the drain body or 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, it is envisaged, according to a further advantageous feature of the invention, for example, peripherally milling in the base plate around the drain opening, an edge or collar to support or seat the siphon or parts of the siphon . A flat contact surface is created through the milled edge for the upper and lower seal of the siphon. It follows from this that, in order to ensure complete drainage in the area of the drainage device, the edge around the drainage opening is lower than the groove or the groove sections. As already explained, in the case of base plates or thin tiles, an edge can be provided to receive the siphon or parts of the siphon with a separating element made of a suitable material, for example ABS plastic. The spacer element is firmly fixed, watertight and non-removable, to the bottom of the base plate during industrial manufacture of the base plate, for example with a suitable adhesive connection.

The drain device advantageously has a drain opening with a siphon, the siphon being in the area of the drain opening arranged tightly, in particular with flanges and, in this case in particular, screwed into at least one base plate or tile of floor, for example of natural / artificial stone, porcelain stoneware, ceramic or similar. The connection between the siphon, on the one hand, and the base plate, on the other hand, can be made indirectly, for example by means of a spacer element that will be discussed later or directly on the base plate. This means that a drainage device is arranged on a base plate of a tile or shower tray, which guarantees 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 is essentially made up of two parts, namely a drain body, which is attached to the base plate from below with a gasket at the drain opening, and a fitting ring, which is screwed to the drain body with a gasket on the motherboard. An advantage of such a siphon known per se is the low installation height and, in particular, also the simple and standardized mounting. The base plates can be completely prefabricated industrially, so they only need to be attached to the flange of the drain body during assembly and screwed through the adjusting ring. It is the same known simple assembly applied in the case of standard shower trays. The base plate is located on the floor or on another subfloor, the subfloor being correspondingly embedded in the area of the siphon, for example a pavement, hard foam panels or the like. The advantage of a shower floor with a single base plate is that only one slope level has to be formed without any additional dividing joints and disadvantageous mounting plates.

The invention also concerns a building with a bathroom, the bathroom comprises at least one wall, a shower arranged in the area 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 groove sections are arranged in the base plate so that the edge of the groove or groove sections are essentially flush with the tiles of the shower wall. From this, it is clear that the edge of the groove is approximately in one plane with the shower wall. In this regard, the slot and the slot sections advantageously extend parallel to the wall. The base plate itself, which preferably extends over the entire surface of the shower floor, has a slope in the direction of the groove or the groove sections. This can be done, for example, by ensuring that the base plate is arranged slightly obliquely on the subfloor of flooring, hard foam panels or the like, or by the fact that the subfloor 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.

The invention is explained in more detail by way of example with reference to the drawings.

Figure 1b shows a section along the line Ib / Ib of Figure 1a;

Figure 2a shows a manufacturing model of a base plate according to Figure 1a, but the design of the cover on the drain device is different;

Figure 2b shows a section along the line IIb / IIb of Figure 2a;

Figures 3a, 3b show a manufacturing model of a base plate according to Figure 1a, the cover projecting over the base plate;

Figures 4a, 4b show a manufacturing model, a spacer element being arranged under the base plate;

Figure 5 shows the spacer element in perspective;

Figure 6 shows the structure of a siphon;

Figure 7 shows a graph of the flow of water over the shower floor.

In Figures 1a, 1b, 2a, 2b, 3a, 3b and 4a, 4b, the same parts are provided with the same reference numerals. The shower floor 1, the shower device of which, for example the shower itself, is not shown, comprises the base plate 3, the base plate 3 having a size that may correspond essentially to the size of the shower floor or be part of a floor with a lot of base plates. The base plate 3 is glued to the floor 5 in the adhesive bed 7; the pavement itself being arranged on the rough concrete floor 9 as a subfloor. One end of the base plate 3 abuts directly with the wall tiles 12 on the wall identified with number 11. At the transition from the tiles 12 towards the base plate 3, a silicone gasket 13 is provided. A sealing sleeve 31 is arranged in the adhesive bed 7 and is approximately 30 x 30 cm in size and extends into the area of the siphon 25. Otherwise, the shower floor is provided with a moisture-permeable coating to form a seal. additional 33. In Figures 1a, 1b and 2a, 2b, the base plate is duplicated, at least in the area of the siphon 25. Such a procedure may be necessary for static reasons if the base plate in the area of the siphon only has a thickness small, as for example is the case with tiles. Regardless of this, a certain height of the water column above the siphon must be ensured so that the siphon achieves a sufficient swallowing capacity. Regardless of static reasons, this can also be achieved because the cover protrudes beyond the base plate 3, as can be seen in Figures 3a, 3b with the cover identified there with the number 46. Such a projection of the cover 46 provides an adequate column of water between the siphon and the bottom of the lid.

To provide a suitable water column, even in the case of thin base plates, a spacer element 50 can be provided between the bottom of the base plate and the siphon, and may, for example, be made of plastic (e.g. ABS) (Figures 4a, 4b and Figure 5).

The spacer element 50 has a flange 52 for fixing to the base plate 3, and a collar 54 for connection to the drain body of the siphon 25 (Figures 4a, 4b, 5). Flange 52 and collar 54 connect an annular body 56, the height is chosen so that a sufficient column of water can be formed over the siphon, even if the cap 58 is flush with the top of the base plate 3 at the case of a slim motherboard. The spacer element 50 can be glued to the base plate as part of the base plate during manufacture, so that it is firmly connected to the base plate. In other words, the siphon can be connected indirectly to the base plate by means of the spacer element or it can be clamped directly to the base plate.

Immediately attached to the wall tile, the base plate 3 has a groove, generally indicated by the number 15, which finally opens into the drain opening 17 of the drain device 19. The groove can also be called a gutter. In detail, the slot 15 comprises two slot sections 15a and 15b, each of which opens into the drain of the slot 21 of the drain device 19 with a slight inclination. The groove drain 21 opens into the drain opening 17. It is envisaged that the groove sections 15a and 15b are higher than the groove drain 21, the groove drain 21 in turn being higher than the edge 23 which it extends around the drain opening 17. In the area of the edge 23, which extends around the drain opening, the siphon, collectively designated by number 25, is arranged.

It has been found in experiments with respect to the formation of the groove or groove sections, that an arc-shaped milled groove or arc-milled groove sections, the groove or groove sections being polished and having a depth of about 0.6. - 1.0 mm, that is, they have no slope, they ensure that due to capillary action, the water film dries not only in the groove, but also around the groove in a very short time. In particular, this also prevents the silicone gasket from becoming unsightly due to the formation of mold at the transition from the base plate to the wall. Therefore, the groove or the groove sections can be kept flat, which facilitates not only cleaning, but also manufacturing in terms of the milling process. A shallow slot is also preferable for optical reasons.

The siphon 25 comprises a drain body 27 and a fitting ring 29, both the drain body 27 and the fitting ring 29 have a joint 30, 32 (figure 6), which can be firmly connected to each other by means of an annular core ( not shown). The trim ring gasket 32 is located at the top of the edge 23, while the drain body gasket 30 27 is arranged adjacent the bottom of the base plate in the edge region. The adjusting ring 29 also has two screws 34, which are arranged opposite each other in the adjusting ring and serving to connect the adjusting ring to the drain body 27 via the base plate in the area of the edge 23.

Furthermore, the screws 34 serve to receive the covers 36 and 46, the cover 36 according to FIG. 1b being at a radial distance 37 from the base plate 3. The radial distance 37 serves to evacuate the water that impacts on the base plate.

The siphon 25 is located, as already indicated, under the base plate 3 within the pavement 5. In order to accommodate the drain body 27 of the siphon 25 on the pavement 5, the pavement 5 has a hole 38 at the corresponding point . The drain body 27 also has a drain tube 40 for connection to the sewer (not shown).

The drain device 19 shown in Figures 2a and 2b differs from that according to Figures 1a and 1b by the fact that in this case the cover 42 extends over the drain device 19 up to the slot 15. The slot drain 21 according to figure 2a is so deep that it extends under the cover 42 into the drain opening 17. Optionally, the cover can also have a plurality of water passage openings 44 in the form of holes to increase the water drainage capacity, in order to also allow the water to drain directly from the base plate 3. Otherwise, the cover 42 rests directly against the base plate 3. Such a procedure also arises in relation to the cover 58 according to with Figures 4a, 4b, which sits directly on the edge 23 of the base plate 3 and extends to the slot sections 15a, 15b. The slot sections 15a, 15b are connected to the drain opening 17 under the cover through the slot drain 21.

Figure 7 schematically shows a top view of the floor of a shower, the arrows indicating the flow of water. The shower floor has a single slope in the direction of the groove. The slot already ensures optimal drainage of the water from the shower floor into the narrow drain opening during the shower process. This effect is due to the vector superposition of the orthogonal flow from the inclined plane of the floor against the rising wall with the transverse flow achieved in the groove area. As a result of this coupling or overlapping of the intersecting flows, very advantageous laminar radial flows or streamlines are created in the drain in the slot area, whereby the drain can be designed to be optically very small with maximum capacity. absorption.
