Description

TECHNICAL AREA

The present invention relates to a bidet assembly according to the preamble of claim 1.

STATE OF THE ART

Mounting frames have become known from the prior art, to which sanitary articles, such as bidets or toilet bowls, and associated elements, such as water supply devices or flushing cisterns, can be fastened. Typically, the assembly frames comprise vertical supports which are connected to one another by horizontally oriented traverses. The trusses usually severely restrict the installation space and the options for routing the cables. For example, bidet arrangements are from the documents EP2740849 A , FR2228141A , DE9216799 U and ITMI20102241 A known.

PRESENTATION OF THE INVENTION

The present invention is based on the object of specifying a drain arrangement which overcomes the disadvantages of the prior art. In particular, it is an object of the present invention to specify a drain arrangement which allows the sanitary article to be well supported.

This problem is solved by the bidet arrangement according to claim 1. Accordingly, a bidet arrangement comprises a mounting frame with two supports arranged at a distance from one another, an upper crossbar and a lower crossbar which lies below the upper crossbar in the installed position, a bidet which is fixed to the upper crossbar and which with a rear bearing surface supported on the lower traverse and a siphon having a siphon inlet attached to a drain opening of the bidet and a siphon outlet to which a drain pipe is connected. The two trusses connect the two supports together. The drain pipe is connected to a building sewage pipe. The drain pipe has a first pipe section, which is the Siphon outlet connects, and a second pipe section and a deflection section lying between the two pipe sections. The deflection section is designed in such a way that the central axis of the second pipe section runs below the central axis of the first pipe section in the installed position. The lower traverse runs above the second pipe section. Because the second pipe section is lower than the first pipe section due to the deflection section, an installation space is created above the second pipe section for the traverse, so that the lower traverse can be positioned at a greater distance from the upper traverse.

In other words, due to the deflection section, the second pipe section is lower than the first pipe section, such that the installation space above the second pipe section for the traverse is increased, so that the lower traverse can be positioned at a greater distance from the upper traverse; or in such a way that the lower traverse comes to lie at least partially below the central axis of the first pipe section in the installed position.

Due to the deflection section, the second pipe section comes closer to the ground in the installed position, as a result of which the lower traverse can also be arranged further down. The deflection section and the lower-lying second pipe section therefore result in the advantage that the distance between the two traverses can be increased or even maximized. This arrangement has the advantage that the support of the bidet on the cross members, in particular on the lower cross member, is improved and that there is still no assembly-related collision between the lower cross member and the drain pipe.

Another advantage of the deflection section, which deflects the pipe downwards, is that the hydraulic resistance due to the downward deflection can be almost or even completely compensated for by improved flow behavior. The aerodynamic loss therefore comes to bear almost or not at all.

The upper traverse is subjected to tensile stress by the bidet or by the bidet and a person sitting on it. The upper traverse can also be referred to as a tension traverse. The lower traverse is subjected to pressure from the bidet or from the bidet and a person sitting on it. The lower traverse can also be referred to as a pressure traverse.

A further advantage of the deflection section is that the compactness of the siphon and the drain pipe is not negatively affected by the deflection section. If the drain pipe were designed without the deflection section, the siphon would be lower if the second pipe section were at the same height. The deflection section allows the siphon to be higher, which ensures the compactness of the siphon and drain pipe.

The expressions "below", "below", "rear", "lower", "higher" etc. used herein are to be understood in the installed position.

• Das Versatzmass in einer ersten Variante ist vorzugsweise grösser als die Hälfte des Durchmessers des ersten Rohrabschnittes bzw. des zweiten Rohrabschnittes ist.
• Das Versatzmass in einer zweiten Variante ist vorzugsweise im Wesentlichen gleich dem Durchmesser des ersten Rohrabschnittes bzw. des zweiten Rohrabschnittes
• Das Versatzmass in einer dritten Variante ist vorzugsweise grösser als der Durchmesser des ersten Rohrabschnittes bzw. des zweiten Rohrabschnittes.

Preferably, the central axis of the second pipe section is lower than the central axis of the first pipe section by an offset amount. The offset can be selected in different ways:

• The amount of offset in a first variant is preferably greater than half the diameter of the first pipe section or of the second pipe section.
• The amount of offset in a second variant is preferably essentially equal to the diameter of the first pipe section or of the second pipe section
• The offset in a third variant is preferably greater than the diameter of the first pipe section or the second pipe section.

The offset is preferably chosen to be as large as possible so that the distance between the two traverses can also be maximized.

The first pipe section preferably lies at least partially in an interior space of the bidet and the second pipe section lies at least partially or mostly or completely outside said interior space. Consequently, the drain pipe with the deflection section is led out from a position lying at least partially in the interior space to a position lying mostly or completely outside the interior space.

The cavity of the bidet, which is accessible from below, is understood as the interior of the bidet.

Depending on the height of the bidet, the second pipe section can be located at least partially outside the interior and is visible from the side. The degree of visibility essentially depends on the height of the bidet, since the siphon as well as the second pipe section are preferably always at the same height and the bidet can be mounted at different heights. In practice, this does not play a major role with regard to aesthetic aspects, since the second pipe section is not visible when the bidet is used as intended. This arrangement outside the interior has the advantage that the second pipe section comes to lie outside an area which is advantageous for supporting the bidet.

In the installed position, the deflection section is preferably positioned in front of the mounting frame. The drain pipe extends through the mounting frame with the second pipe section.

The deflection by the deflection section therefore takes place at a distance from the mounting frame. In this way, a collision with the lower strut and the second pipe section or the deflection section can be avoided. The deflection section allows the second pipe section to be routed below the lower traverse in the direction of the domestic installation.

The second pipe section preferably intersects a plane that is spanned by the bearing surface, outside the bearing surface. This means that when the bidet is viewed from behind, the second pipe section lies below the bearing surface and thus below the bidet.

The second pipe section lies under the bearing surface and therefore does not intersect it due to its location outside the bearing surface. This in turn allows for the lowest possible arrangement of the traverse and also avoids the second pipe section colliding with the lower traverse when the bidet is being stored.

Preferably, the lower traverse is in contact with the bearing surface with its surface facing the bidet over the entire height of this surface. Due to the fact that the second bearing section does not intersect the bearing surface but is arranged outside of the bearing surface, a collision with the traverse can be avoided.

The second pipe section is preferably located completely below the outflow edge of the

siphon outlet. This means that the pipe wall lies below the outflow edge at the maximum extension of the pipe section upwards.

The outflow edge of the siphon outlet is the edge over which the waste water can flow out of the siphon. The outflow edge can be part of the siphon or the first pipe section.

The bearing surface is preferably designed as a surface area which, viewed in the direction of the surface normal from behind on the bearing surface, is provided with an outer boundary edge which corresponds to the outer edge of a side wall of the bidet.

As mentioned above, the second tube section lies outside this bearing surface and thus also outside the boundary edge.

The deflection section is preferably provided by two 45° pipe bends, in particular one directly behind the other. The two 45° pipe bends are preferably arranged in opposite directions. This means that one pipe bend runs clockwise and the other pipe bend counterclockwise. As a result, a deflection section can be created which is comparatively easy to provide.

Preferably, the lower crosshead contacts an area of the bearing surface that is near the bottom of the bidet. Thus, the point of contact with the lower traverse is arranged as far down as possible, as a result of which the supporting effect for the bidet can be improved.

Preferably, the distance between the central axis of the upper crossbar and the central axis of the lower crossbar is greater than one-half or two-thirds the height of the bidet.

Preferably, the drain pipe is attached to the upper and/or lower traverse with a pipe attachment element. The pipe fastening element is preferably a pipe clamp.

The siphon outlet is preferably oriented upwards and the first pipe section is connected to the siphon outlet via a 90° pipe bend.

Depending on the design of the siphon, it has a U-shaped pipe section which is secured to the siphon inlet and outlet by threaded sockets. For cleaning work, the U-shaped pipe section can be separated from the siphon inlet and siphon outlet.

The first pipe section preferably has an enlarged cross section in the vicinity of the siphon outlet. As a result, the drain pipe can be designed with a larger diameter than the siphon, which is advantageous for the drain capacity.

The upper crossbar preferably has at least one fastening point for receiving a fastening element for fastening the bidet to the upper crossbar. The fastening point can, for example, be a thread fixedly arranged in the upper traverse, the fastening element being a screw or a threaded rod.

Preferably, there is a pre-wall between the mounting frame and the bidet, the bidet being attached to the upper cross-member via the pre-wall and the bidet standing on the lower cross-member via the pre-wall. The pretext can be, for example, a tiled plasterboard.

The mounting frame, that is, the supports and the trusses are preferably made of metal. The traverses are mechanically firmly connected to the supports in such a way that a force can be introduced from the traverses into the supports. Preferably, the traverses are connected to the supports via a positive and/or non-positive and/or material connection.

In the installation position, the supports stand on the floor and are firmly screwed to the floor. Further, the supports typically connect to the wall of the building.

Further embodiments are specified in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the Figures 1 to 3 an embodiment of a bidet arrangement 1 according to the invention is shown. The bidet arrangement 1 comprises a mounting frame 2, a bidet 6 which is fixed to the mounting frame 2, a siphon 8 which is connected to the bidet 6 and a drain pipe 12 which is connected to the siphon 8.

The mounting frame 2 comprises two spaced supports 3, an upper cross member 4 and a lower cross member 5. The lower cross member 5 is in the installed position below the upper cross member 4. The two cross members each extend from support 3 to support 3 to connect the two support each other. The trusses 4, 5 and the supports 3 are connected to one another via a mechanically strong connection. In the embodiment shown, the supports 3 comprise extendable footrests 25. The assembly stand 2 stands on a building floor G via the footrests 25 and can be fixed to it.

The bidet 6 has a bearing surface 7 on the back. The bidet 6 is firmly fixed to the upper traverse 4 and rests with the bearing surface 7 on the lower traverse 5 . Attachment points 23 are present on the upper traverse 4 . The bidet can be fixed accordingly with a fastening element 24 via these fastening points 23 . The fastening element 24 is, for example, a threaded rod and the fastening point 23 is a thread on the upper traverse 4. The bidet 6 is supported on the lower traverse 5 via the bearing surface 7 arranged on the rear. The upper traverse 4 is on train and the lower Traverse 6 is loaded in compression.

The siphon 8 is formed with a siphon inlet 9 attached to a drain opening 10 of the bidet 6 and a siphon outlet 11 communicating with the drain pipe 12 . Water that flows out of the drain opening 10 from the bidet 6 can be supplied to the siphon 8 via the siphon inlet. The siphon outlet 11 is followed by the drain pipe 12, which can be connected at the end to a sewage pipe, not shown.

Based on figures 1 , 3 and 4 the formation of the drain pipe 12 and the arrangement of the drain pipe 12 with respect to the lower traverse 5 is explained. The drain pipe 12 comprises a first pipe section 13 and a second pipe section 14 as well as a deflection section 15 located between the two pipe sections 13, 14. The lower traverse 5 runs transversely to the drain pipe 12 and above the second pipe section 14. The second pipe section 14 is seen in the installed position deeper than the first pipe section 13. This creates an installation space for the lower cross member 5, which allows the lower cross member 5 to be positioned at a greater distance from the upper cross member 4. With this arrangement, the traverse can be pushed down as far as possible, so that the distance between the upper traverse 4 and the lower traverse 5 is as great as possible, which is advantageous for the support of the bidet 6 overall.

In the embodiment shown, the deflection section 15 is designed in particular in such a way that the central axis M14 of the second pipe section 14 is positioned below the central axis M13 of the first pipe section 13 when installed, such that the lower cross member 5 is at least partially below the central axis M13 of the first pipe section 13 comes to rest.

The central axis M14 of the second pipe section 14 is lower by an offset Z than the central axis M13 of the first pipe section 13. In the embodiment shown, the offset corresponds to the diameter of the first pipe section 13 or the second pipe section 14. In other embodiments, the offset Z can also be greater or be smaller.

Preferably, the second pipe section 13, as in cross section according to FIG figure 3 shown, at least partially arranged in an interior space 16 of the bidet 6. The interior 16 of the bidet is a cavity that is accessible from below, but in installation position cannot be seen. In the embodiment shown, essentially the upper half of the first pipe section 13, seen in cross section, is in the interior space 16. The second pipe section 14 of the drain pipe 12 is here completely outside the interior space 16. The second pipe section 14 is preferably located at a slight distance from a lower edge 26 of the bidets 6

The configuration shown in the figures has the particular advantage that the second pipe section 14 is as far down as possible, so that the lower traverse 5 is also as far down as possible and that the siphon 8 does not protrude too far out of the interior 16 .

Seen in the installed position, the deflection section 15 is in front of the assembly frame 2. This means that the deflection section 15 is at a distance from the front side of the assembly frame 2. The drain pipe 12 with the second pipe section 14 then extends through the assembly frame 2. This means that in the area where the drain pipe 12 passes through the mounting frame 2 , the drain pipe extends through the mounting frame 2 exclusively with the second pipe section 14 .

With reference to the figure 2 It can be seen that the second pipe section 14 intersects a plane E, which is spanned by the bearing surface 17 of the bidet 6, outside of the bearing surface 7. The level E can also be referred to as the assembly level and is the level with which the bidet 6 is attached to the assembly frame 2 .

The bearing surface 7 is designed as a surface area 18 which is provided with an outer boundary edge 19 when viewed from the rear toward the rear of the bidet 6 in the direction of the surface normal. These items are in the figure 2 drawn. The outer boundary edge 19 corresponds to the outer edge of a side wall of the bidet 6. The side wall bears the reference number 20. When viewed in the direction of the surface normal F, the second pipe section 14 extends in such a way that the second pipe section 14 lies outside the surface area 19.

The lower traverse 5 comes into contact with a lower area 21 of the bearing surface 7 which is close to the lower end 27 of the bidet 6 . The lower area 21 is part of the surface area 18 of the bearing surface 7.

The distance A between the central axis of the upper traverse 5 and the central axis of the lower traverse 6 is preferably greater than half or two thirds of the height H of the bidet 6.

In the embodiment shown, the drain pipe 12 is fastened to the mounting frame 2 with a pipe fastening element 22 . The pipe fastening element 22 is here a pipe clamp and a fixing rod which is fastened to the upper traverse 4 . Fastening to the lower traverse 5 is also conceivable.

The siphon outlet 11 is oriented upwards in the installed position. The first pipe section 13 is connected to the siphon outlet 11 via a 90° pipe bend. In the area of this 90° pipe bend, the first pipe section 13, here in the vicinity of the siphon outlet 11, has an enlarged cross section. This means that the diameter of the first pipe section 13 increases in the area where the first pipe section 13 begins.

In the embodiment shown, the deflection section 15 is provided by two 45° pipe bends 17 lying directly one behind the other. The first pipe bend 17 is, as of the figure 4 as can be seen, is curved in a counter-clockwise direction and the second pipe bend 17 is curved in a clockwise direction.
