Description

The invention relates to a drain fitting for a Bodenablaufrinne, with a fixable at a drain opening of the floor drainage housing, which is formed from a pot-like housing lower part and a lid-like housing upper part, the housing upper part having an inlet opening and the housing lower part having an outlet opening, wherein the inlet opening of an annular seal is surrounded, wherein in the housing odor trap is arranged, which has a separately manufactured cup or cup-shaped container and a projecting into the container dip tube, and wherein the dip tube is removably held at the inlet opening of the housing.

Furthermore, the invention relates to a floor drainage channel, in particular shower channel, with an elongated trough, in the bottom of which an outlet opening is formed, and a drainage opening of the abovementioned type which can be fixed to the outlet opening.

Such waste is from the EP 2 149 643 A2 known. In the known drain fitting, which can be used with gutter-shaped housing also in shower channel systems, the average horizontal outer diameter of the cup-shaped container is greater than the average inner diameter of the inlet opening. In order to be able to use the waste set optionally with and without odor trap, the container is at least partially flexible, so that it is compressible to the extent that it can be removed from the housing in the compressed state through the inlet opening and into the Housing is used. The container is made entirely or at least partially of rubber-elastic material.

The available installation space, in particular the available height for a waste fitting, which is arranged below a floor drainage channel (shower channel) is generally very limited. The required height is determined in particular by the required for a reliable odor trap sealing water level. The sealing water level should be such that the odor trap is effective even after a certain period of time, in which the sealing water level decreases without new water supply by evaporation. Furthermore, the space required for such a drain set, in particular the height, determined by the required drainage capacity to sufficiently fast and reliable drainage of the wet cell, e.g. to ensure a shower. In particular, in connection with high-performance shower systems floor-level shower channels is required a safe drainage performance.

Various floor drain fittings have already been developed, which offer a reliable odor trap and a reliable drainage performance at a relatively low overall height (see, for example, US Pat EP 2 305 905 B1 ). In particular, for the use of floor drainage channels, however, there is still a need for a compact pop-up waste, which offers a reliable odor trap and high drainage capacity with low height and compact circumferential dimensions.

In the DE 20 2008 001 013 U1 is described a pop-up fitting for showers or bathtubs, which has a housing with an inflow opening and a drain neck. In the housing, a the inflow limiting, a part of an odor trap forming dip tube is used. The inflow opening is surrounded by a seal which is applied to the underside of the tub bottom. In this case, the housing has a drain channel surrounding the odor trap, which is bounded above by a housing wall section, wherein this housing wall section is higher than the seal and surrounds the seal.

The EP 2 305 905 A1 discloses a drainage for floor-level showers with a cup-shaped drain housing having a cup-shaped, connection piece-free bottom part, a laterally arranged connection piece and at its top an inlet opening. In addition, a dip tube is present, which can be inserted via the inlet opening in the drain housing and defines a smell trap with this. The bottom part of the process is height adjustable and liquid-tight connected to the drain body.

Based on this, the present invention seeks to provide a drain fitting of the type mentioned above, which has a reliable odor trap, a high drainage capacity allows and can be realized in compact circumferential dimensions, so that in combination with the floor drainage trough overall results in a low overall height.

This object is achieved by a pop-up waste with the features specified in claim 1. Preferred and advantageous embodiments of the inventive waste set are specified in the dependent claims.

The waste fitting according to the invention is characterized in that in the upper housing part a pocket-like recess is formed, which is arranged outside of the inlet opening surrounding the seal and the upper edge of the inlet opening projects beyond the bulge and an upper edge of the cup or cup-shaped container Overflow channel, part of which extends above the upper edge of the inlet opening, the cup-shaped or cup-shaped container having inside at least two horizontally spaced projections, and wherein the dip tube has on its outer side at least one projection which cooperates with the projections of the container, to lock the container against rotation and horizontal displacement.

The waste set according to the invention allows use of space directly under the flange, the gutter body of a floor drainage channel usually identifies. As a result, reduced circumferential dimensions for a generic waste set can be achieved while maintaining a reliable odor trap and a safe drainage performance, the required height for the system composed of gutter body and waste set is comparatively low.

In addition, the drain fitting according to the invention is characterized by a reliable locking of the cup or cup-shaped container in the housing cavity.

An advantageous embodiment of the drain assembly according to the invention provides that the cup or cup-shaped container after removal of the dip tube is rotatable in the housing and is locked in a predetermined position in relation to the upper-side bulge of the housing by means of the inserted into the inlet opening dip tube. With this configuration, the drainage performance of the drain set can be further optimized for compact or reduced housing dimensions. In addition, this can be safely prevented by reducing the drainage performance due to an unwanted displacement of the cup or cup-shaped container in the direction of the outlet opening.

A further advantageous embodiment of the drain fitting according to the invention is characterized in that the lower housing part has an annular wall portion which is rotatably and watertightly connected to an annular wall portion of the upper housing part. This embodiment allows the lower housing part to be rotated relative to the upper housing part about a vertical axis by up to 360 °. The outlet opening of the lower housing part, which is preferably formed in the form of a pipe socket formed on the lower housing part, can thus be aligned very easy to install with regard to a favorable or predetermined course of the sewage pipe. In practice, if necessary, usually a rotation of the lower housing part relative to the upper housing part by a maximum of 180 ° sufficient.

A further advantageous embodiment of the waste fitting according to the invention is characterized in that the cup-shaped or cup-shaped container on the bottom side has a wave-shaped projection which projects in the direction of dip tube and extending from an inner wall side of the container to an opposite inner wall side of the container. The wave-shaped projection has a favorable effect on the deflection of the running through the dip tube water and thus contributes to increasing the drainage performance of the drain set.

Furthermore, the problem underlying the invention is achieved by a floor drainage channel, in particular shower channel, with the features of claim 5.

The floor drainage channel has an elongated trough, in the bottom of which a discharge opening is formed. At the drain opening is a pop-up with a fixable at the drain opening housing can be fixed, which is formed from a pot-like housing lower part and a lid-like housing upper part, wherein the upper housing part has an inlet opening and the lower housing part has an outlet opening, wherein the inlet opening is surrounded by an annular seal. In the housing, a smell trap is arranged, which has a separately manufactured cup or cup-shaped container and a projecting into the container dip tube, wherein the dip tube is removably held at the inlet opening of the housing. In the upper housing part, a pocket-like recess is formed, which is arranged outside of the seal surrounding the inlet opening and the upper edge of the inlet opening projects beyond the bulge and an upper edge of the cup or cup-shaped container defining an overflow channel, of which a part above the upper edge of the inlet opening extends. On the circumferential wall of the trough, a circumferential flange connects to the upper side, wherein the upper-side bulge of the upper housing part of the drain fitting is arranged in a space bounded by the wall of the trough and the flange space.

Preferably, the cup or cup-shaped container has an elongated, for example, substantially oval ground plan shape and is rotatably disposed or insertable in the housing or housing lower part of the drain assembly. By a corresponding rotation of the container (cup) or positioning thereof relative to the pocket-like bulge of the upper housing part, the bulge can be optimally used as an overflow space.

The cup or cup-shaped container is preferably made of rigid material, for example made of rigid plastic or metal.

An advantageous embodiment of the drain fitting of the floor drainage channel is characterized in that the cup-shaped or cup-shaped container is shaped such that it can be removed without destruction and removed again after removal of the dip tube via the inlet opening from the housing. The dip tube and the container can thus be removed for cleaning purposes. In particular, this design provides, after removal of the two odor trap components, free access to the outlet opening of the housing and the sewer line connected thereto.

According to a further preferred embodiment, the inlet opening of the drain fitting of the floor drainage channel is elongate, preferably formed as an elongated oval or oblong hole. As a result, a cup-shaped or cup-shaped container designed in accordance with the ground plan can be inserted into the housing via the inlet opening and thus increase the drainage capacity, in particular in the case of very narrow shower channels with a correspondingly elongated channel drain opening.

In this context, it is also advantageous if the cup or cup-shaped container according to a preferred embodiment has a substantially elongated round, preferably substantially oval ground plan shape. As a result, the volume of sealing water can be increased, thereby lengthening the time to a loss of the sealing water function caused by evaporation.

The length of the inlet opening or of the cup-shaped or cup-shaped container is for example at least twice the width of the inlet opening or of the container.

A further advantageous embodiment of the drain fitting of the floor drainage channel is characterized in that the bottom of the housing base has a substantially centrally disposed, wart or dome-shaped elevation projecting into the housing cavity, and that the bottom of the cup or cup-shaped container on the outside a recess or Denting has, in which the wart or dome-shaped elevation of the bottom of the housing base engages positively in the proper operating condition of the drain fitting. This configuration contributes with simple means for locking the container in the housing cavity.

In order to use a relatively large cup or cup-shaped container in the housing on the inlet opening of the lid-like housing upper part and to remove it from the same if necessary, and yet to ensure the odor trap function, provides a further embodiment of the drain assembly according to the invention that the dip tube on the top a funnel-shaped flange whose peripheral shape corresponds to the shape of the inlet opening of the lid-like housing upper part.

The vertical longitudinal central axis of the inlet opening and / or the dip tube inserted into the housing preferably runs parallel and spaced from the vertical axis of rotation of the housing base and / or the cup or cup-shaped container arranged in the housing. The distance of the axis of rotation from the vertical longitudinal center axis of the inlet opening is for example in the range of quarter to one third of the immersion tube inner diameter.

A further advantageous embodiment of the drain fitting of the floor drainage channel is characterized in that the lower housing part is frictionally connected with the upper housing part with the interposition of a sealing ring. This embodiment simplifies the manufacture and assembly of lower housing part and upper housing part. In particular, in this case, in the case in which the lower housing part is rotatable relative to the upper housing part, the liquid-tightness of the rotary joint is ensured.

With regard to a simple installation of the drain fitting of the floor drainage channel, it is advantageous if, according to a further embodiment, the housing upper part is provided on the outside with ear-shaped holders which have through holes for the passage of threaded bolts fastened or fastened to the drainage channel.

In order to fix the waste fitting on the floor drainage channel, fastening means in the form of threaded bolts or nuts may preferably be fastened to the underside of the groove base body, on opposite edge regions of the drainage opening.

The in Fig. 1 shown basic body 1 a floor drainage channel, in particular shower channel, has an elongated trough 2. At the circumferential wall 2.1 of the trough 2, the upper side, a circumferential flange 2.2 connects. The flange 2.2 is angled towards the wall 2.1 to the outside and extends substantially horizontally. The bottom 2.3 of the gutter base body 1 has a drain opening 2.4. Preferably, the bottom 2.3 is formed starting from the ends of the trough 2 in the direction of the drain opening 2.4 with a slope. The trough 2 can be covered, for example, by a grate (not shown) or an inlet slit delimiting plate (not shown).

The drain opening 2.4 of the gutter base body 1 is formed as a slot. It has an approximately oval shape with two mutually parallel edge portions 2.41, 2.42 and two semicircular edge portions 2.43, 2.44. The mutually parallel edge portions 2.41, 2.42 of the drain opening 2.4 are preferably located directly on the vertical wall 2.1 of the trough 2. At the drain opening 2.4, the housing 3 of a waste set according to the invention is fixed.

For this purpose, a plate 2.5 is firmly bonded to the underside of the groove base body 1, for example, welded ( Fig. 7 ). The plate 2.5 comprises an opening 2.51, whose shape corresponds to the drain opening 2.4 of the gutter base body 1. The two openings 2.4, 2.51 are congruent to each other. The plate 2.5 projects beyond the longitudinal edges 1.1, 1.2 of the underside of the channel base body 1 on both sides in order to provide a contact surface for a seal 4 arranged between the channel base body 1 and the housing 3 of the drain fitting. On the plate 2.5 four threaded bolts 5 are attached, for example, welded. The threaded bolts 5 extend vertically downward from the plate 2.5 and are in pairs at corners of the plate 2.5, spaced from the semicircular edge portions 2.43, 2.44 of the oval drain opening 2.4.

The housing 3 is composed of a pot-like housing lower part 3.1 and a cover-like housing upper part 3.2. The upper housing part (cover) 3.2 has an inlet opening 3.21 and the lower housing part (housing pot) 3.1 an outlet opening 3.11. The shape of the inlet opening 3.21 corresponds to the shape of the drain opening 2.4 of the channel base body 1. The upper housing part 3.2 is provided on the outside with ear-shaped brackets 3.22, the through holes 3.23 for inserting the attached to the gutter 1 threaded bolt 5 have.

The lid-like housing upper part 3.2 has an annular wall section 3.24. Adjacent to this wall section 3.24, a circumferential annular web 3.25 is integrally formed on the inside of the housing upper part. The annular wall section 3.24 and the web 3.25 define an annular gap 3.26. The pot-like housing base 3.1 also has an annular wall section 3.12. This wall section 3.12 can be inserted into the annular gap 3.26 of the upper housing part 3.2, so that the lower housing part 3.1 is rotatably connected to the annular wall section 3.24 of the upper housing part 3.2. On the outside of the pot-like housing lower part 3.1 circumferential ribs 3.13, 3.14 are formed, which define an annular groove in which on the ribs 3.13, 3.14 radially outwardly projecting sealing ring (O-ring) 6 is arranged. In the assembled state of the lower housing part 3.1 of the O-ring 6 is sealingly against the inside of the annular wall portion 3.24 of the upper housing part. The lower housing part 3.1 is frictionally connected by the sealing ring 6 with the upper housing part 3.2.

The inlet opening 3.21 of the upper housing part 3.2 is limited by a circumferential collar 3.27. The inlet opening 3.21, in particular the collar 3.27, is surrounded by an annular seal 4 whose shape is adapted to the shape of the inlet opening 3.21 and the collar 3.27 and, accordingly, oval or nearly oval is trained. The seal 4 is designed in this embodiment as a flat gasket and has the upper side circumferential ribs 4.1 (see Fig. 2 ).

The attachment of the upper housing part 3.2 on the gutter body 1 by means of nuts 7, which are screwed by inserting the threaded bolt 5 through the ear-shaped brackets 3.22 of the upper housing part with interposition of washers 8 on the threaded bolt 5 (see FIGS. 7 and 8 ).

Then, provided with the sealing ring (O-ring) 6 edge of the pot-like housing base 3.1 is inserted into the annular gap 3.26 of the upper housing part 3.2, so that a watertight rotary connection of the housing base 3.1 results with the upper housing part 3.2. Alternatively, the lower housing part 3.1 but also already connected to the upper housing part 3.2, before the latter is attached to the gutter body 1.

In the housing 3, a removable odor trap is arranged, which is formed from a cup-shaped or cup-shaped container 9 and a dip tube 10 ( Fig. 11 ). The container (cup) 9 has a substantially oval plan shape. It consists for example of plastic and is preferably rigid. Its ground plan shape substantially corresponds to the shape of the drain opening 2.4 of the channel base body and the shape of the inlet opening 3.21 of the upper housing part. Its outer dimensions are slightly smaller than the inner dimensions of the inlet opening 3.21 and the inner dimensions of the drain opening 2.4, so that it can be removed and reused from the housing 3 via the inlet opening 3.21 and the drain opening 2.4 (see 11 and FIG. 12 ).

After the container (cup) 9 is inserted through the drain opening 2.4 and the inlet opening 3.21 in the housing 3, it is pivoted, so that its parallel straight wall sections 9.1, 9.2 transverse to the mutually parallel straight edge sections 3.28, 3.29 of the inlet opening 3.21 run (see. FIGS. 12 and 13 ).

Thereafter, the dip tube 10 is inserted into the housing 3 and the container 9. The dip tube 10 has at its upper end a funnel-shaped flange 10.1, the peripheral shape of which corresponds to the shape of the inlet opening 3.21. The flange 10.1 is integrally formed on the dip tube 10. At the round sections 3.30, 3.31 of the inlet opening 3.21 limiting collar 3.27 radially inwardly projecting webs or ribs 3.32, 3.33 are formed, which serve as stops for the Tauchrohrflansch 10.1. The stops 3.32, 3.33 define the vertical position of the dip tube 10 relative to the bottom 9.3 of the container 9 or cup-shaped housing lower part 3.1. The flange 10.1 has in its outer edge surface 10.2 a circumferential groove into which a sealing ring (O-ring) 10.3 is inserted. The O-ring 10.3 projects slightly beyond the edge surface 10.2 and seals the flange 10.2 against the collar 3.27 of the inlet opening 3.21 of the housing upper part 3.2.

At the flange 10.1 of the dip tube closes down the tubular section 10.4. The tubular section 10.4 has a circular cylindrical or almost circular cylindrical inner contour. On the outside of the tubular portion 10.4 of the dip tube at least one projection 10.5 is provided, which cooperates with integrally formed on the inside of the container (cup) 9 projections 9.4, 9.5 to lock the container 9 against rotation and horizontal displacement (see. FIGS. 11 and 14 ).

Furthermore, the bottom 3.15 of the lower housing part 3.1 has a substantially centrally arranged, wart-shaped or dome-shaped elevation 3.16, which protrudes into the housing cavity (cf. Fig. 4 and Fig. 9 ). The bottom 9.3 of the container (cup) 9 is provided on the outside with a depression or indentation 9.6, in which the dome-shaped elevation 3.16 of the housing bottom 3.15 engages positively in the proper operating state of the drain fitting ( Fig. 4 ).

In the upper housing part 3.2 a pocket-like bulge 3.34 is formed, which is arranged outside of the inlet opening 3.21 surrounding seal 4 and the upper edge 3.211 of the inlet opening 3.21 projects beyond the top. The bulge 3.34 delimits with the upper edge 9.7 of the container (cup) 9 an overflow channel, part of which runs above the upper edge 3.211 of the inlet opening 3.21 (see FIG Fig. 2 and Fig. 4 ). In the FIGS. 4 and 6 The reference symbol W and the arrows indicate the flow direction of the water W flowing into the waste fitting via the drain opening 2.4 and the dip tube 10.

The bulge 3.34 of the upper housing part 3.2 has a flattening on the upper side 3.341 and directly adjoins the underside of the channel flange 2.2. Preferably, the bulge 3.34 is located on the underside of the channel flange 2.2.

The outlet opening 3.11 of the pot-like housing lower part 3.1 is formed in the form of a molded thereon pipe socket 3.17. The pipe socket 3.17 is preferably without height offset in the outer bottom surface of the housing part 3.18 3.1.

The in the Figures 16 and 17 illustrated drain set differs from that in the FIGS. 1 to 15 shown drain assembly in that the container 9 has a corrugated projection 9.8 on the bottom side, which protrudes in the direction dip tube 10 and extends from an inner wall side of the container 9 to an opposite inner wall side of the container 9. The wave-shaped projection 9.8 improves the deflection of the running through the dip tube 10 water and thus leads to a flow optimization.

The dip tube 10 may be provided on its upper side with a bow-shaped handle 10.6, so that it can be easily pulled out of the housing 3, if necessary, especially for cleaning purposes, without tools.

The embodiment of the invention is not limited to the embodiments shown in the drawing. Rather, numerous variants are conceivable, which make use of the invention specified in the appended claims, even with a different design. Thus, the pipe socket 3.17, for example, with height offset above the outer bottom surface (bottom) 3.18 of the housing base 3.1 may be arranged. Furthermore, the outlet opening 3.11 with the pipe socket 3.17 does not necessarily have to be arranged laterally on the housing lower part 3.1; it can also be formed in the bottom 3.15 of the housing base 3.1, wherein the pipe socket 3.17 then extends substantially vertically.
