Floor drain, especially in the form of a shower channel

Abstract

Floor drain (1) with a base support (2), characterized in that the base support (2) has an opening (3) and the shower drain (1) has a cover (4) which covers this opening (3) and has an outflow (5) which is smaller than the opening (3).

Description

[0001] The present invention relates to a floor drain, such as in particular a shower drain, a drain in the bathroom or on a bathtub or shower tray and in particular a shower channel or a point drain for floor-level showers.

[0002] The invention is based on the objective of realizing a particularly maintenance-friendly and revision-capable design.

[0003] This problem is solved with a floor drain having the features of claim 1.

[0004] Advantageous further training is the subject of the sub-claims.

[0005] The invention makes it possible to service or replace the underlying siphon or other functional units without damaging the surrounding floor structure. The aim is to create a permanently leak-proof yet easily maintainable drainage system, which is particularly suitable for use in modern wet rooms.

[0006] The floor drain comprises a base frame that is integrated into the screed, the screed replacement layer, or a prefabricated form such as a bathtub or shower tray and is sealed via a central opening. A cover is mounted on this base frame, concealing this opening. The cover itself has a drain opening with a smaller cross-section than the opening in the base frame. This creates an inspection area accessible from above, allowing for the removal of the underlying components, particularly a siphon. The cover can be screwed to the base frame or secured with a snap-fit ​​connection. A circumferential seal between the cover and the base frame ensures a reliable seal against water ingress.

[0007] A removable strainer can be installed in the drain area to trap coarse debris and is easily removed for cleaning. The cover can also be fitted with an aesthetically pleasing finish, such as a tileable surface or a stainless steel plate, to match the drain's appearance to the surrounding bathroom decor.

[0008] The base frame can have height-adjustable feet, allowing for precise adjustment to the on-site installation height and simplifying installation. The entire assembly can be configured as either a point drain or a shower channel, depending on the design requirements of the project. When combined with a siphon positioned below the base frame, this configuration allows for complete siphon maintenance from above through the opening in the base frame. The siphon can be removed, inspected, or replaced through this opening without having to open the floor or damage the waterproofing layer.

[0009] This modular structure ensures long-term maintainability, facilitating repairs, preventing water or mold damage, and significantly extending the service life of the entire drainage system. The invention thus contributes to a sustainable and cost-effective design of wet rooms, particularly with regard to future maintenance work.

[0010] An embodiment of the invention is described in more detail below with reference to the figure. It shows the Fig. 1. A perspective view of a shower drain 1 with siphon and the Fig.Figure 2 shows a schematic sectional view of a shower drain 1 according to the invention in its assembled state. This view shows the base support 2, which is permanently integrated into the building structure and has a central opening 3. This opening is covered by a cover 4, which is located in the area of ​​the opening 3 and includes a smaller drain opening 5. A circumferential seal 6 is located between the cover 4 and the base support 2, ensuring a watertight connection. A removable strainer 7 is positioned in the area of ​​the drain opening 5, which allows for the collection of hair and coarse dirt particles. The cover 4 can be connected to the base support 2 via screw connections 8. A decorative cover 9, which is either tileable or made of metal, is also provided on the cover 4.The siphon 10 is located below the base support 2, positioned directly under the opening 2, and can be opened or replaced through this opening as needed. The base support is fixed in the screed via height-adjustable feet 11, allowing for flexible adaptation to the local conditions.
