Abstract

A wastewater drain including an odor trap that includes a shallow housing (3), a cover (12) that can be connected to the shallow housing, and an inlet connector connected to the cover (12). The wastewater drain is a jacket-shaped, preferably cylindrical, base insert is placed in the receptacle forming the edge of the depression, connected in a sealed manner to the shallow housing (3) and ends beneath the cover side, forming a retaining wall, and a drainage channel surrounding the retaining wall of the base insert is formed, which opens into the lateral discharge opening of the discharge connector and has a gradient contour which is inclined toward this connector. Also disclosed is a shower base element (2) including a wastewater drain (1), in which the wastewater drain (1) is integrated in the shower base element (2).

Claims

1. A wastewater drain (1) comprising an odor trap, comprising:

a shallow housing (3) having a base (4), a housing side wall (5) which is closed with the exception of a lateral discharge opening (18), and a cover side (7) which is open toward the top and located opposite the base (4);

a cover (12) which can be connected to the shallow housing (3) and has a cover side wall (13), which protrudes into the shallow housing (3) when installed; and

an inlet connector (16), which is connected to the cover (12) and ends with a downwardly protruding, tubular drain (49) above a depression (61) which is introduced in the base (4), the inlet connector being surrounded by an odor trap assembly,

characterized in that

a jacket-shaped, preferably cylindrical, base insert (9) is placed in a receptacle (8) forming the edge of the depression (61), connected in a sealed manner to the shallow housing (3) and ends beneath the cover side, forming a retaining wall (22), and

a drainage channel (33) is formed surrounding the retaining wall (22) of the base insert (9), which opens into the lateral discharge opening of the discharge connector (18) and has a gradient contour (43) which is inclined toward this connector.

2. The wastewater drain according to claim 1, characterized in that the cover (12) comprises an attachment (14), which has a receptacle (15) for the inlet connector (16) and a cover face (17) surrounding the attachment (14).

3. The wastewater drain according to claim 1, characterized in that an adapter piece (46) is provided with a receptacle (24), which is connected to a drainage connector (6) of the shallow housing.

4. The wastewater drain according to claim 1, characterized in that a dome (10), which forms a support element for a cover grate (11), projects upward centrally from the depression (61).

5. The wastewater drain according to claim 4, characterized in that the dome (10) projecting upward from the depression (61) has a contour which is advantageous in terms of flow, whereby water flowing into an inlet chamber (53) through the cover (12) is transferred into an intermediate chamber (52) with low resistance.

6. The wastewater drain according to claim 4, characterized in that the dome (10) has a conical shape.

7. A wastewater drain according to claim 1, characterized in that two annular faces (A1;

A2) are formed at the level of a lower edge (27) of the inlet connector (16), wherein;

the inner annular face (A1) is delimited on the inside by an outer contour (28) of the dome (10) and on the outside by an inner contour (29) of the inlet connector (16);

the outer annular face (A2) is delimited on the inside by the outer contour (30) of the inlet connector (16) and on the outside by an inner contour (31) of the base insert (9);

and the size of the inner annular face (A1) is approximately 50% to 65% of the size of the outer annular face (A2).

8. The wastewater drain according to claim 1, characterized in that the vertical distance (H1) between an upper edge (32) of the base insert (9) and a lower edge (27) of the inlet connector (16) is less than 40 mm.

9. The wastewater drain according to claim 1, characterized in that the center (M1) of the tubular base insert (9) is arranged offset relative to the side on which the drainage connector (6) is disposed, whereby the drainage channel (33) continuously widens, starting from a narrowest point (34) opposite the drainage connector (6) in the direction of the drainage connector (6).

10. The wastewater drain according to claim 1, characterized in that a drainage connector (6) of the shallow housing (3) has a horizontal opening width (W1) and a vertical opening width (W2), (W1) being greater than (W2).

11. The wastewater drain according to claim 3, characterized in that the shallow housing (3) is integrally connected to the adapter piece (46).

12. The wastewater drain according to claim 11, characterized in that a channel (26) located inside the adapter piece (46) tapers away from the receptacle (24) in the direction of an outlet connector (25) and transitions into a round tube.

13. A wastewater drain according to claim 1, characterized in that a support element (39) is provided in the shallow housing (3) in the region of a transition (38) to a drainage connector (6), the element supporting the cover (12).

14. A wastewater drain according to claim 1, characterized in that a height equalization element (47) is provided, which can be connected to an attachment (14) of the cover (12).

15. A shower base element (2) comprising a wastewater drain (1) according to claim 1, characterized in that the wastewater drain (1) is integrated in the shower base element (2).

16. The shower base element (2) according to claim 15, characterized in that a total height (H) of the shower base element (2) is no more than 65 mm.

17. The shower base element according to claim 15, characterized in that an upper side (40) of the shower base element (2), in the region of the wastewater drain (1), comprises a penetration (48) which is suitable for accommodating an attachment (14) of the cover (12) with precise fit, no further penetrations being present on the upper side (40) of the shower base element in the region of a drain pan (41).

18. A method for producing a shower base element (2) according to claim 1, characterized by the following method steps:

a. providing a bed plate (42);

b. introducing a gradient contour (60) on one side of the bed plate (42), the contour being directed toward the drain;
