Description

Technical field

[0001] The present invention relates to a drain strainer according to the preamble of claim 1. In particular, the invention relates to a drain strainer for use in drains such as sinks, washbasins, showers or similar installations, especially a drain strainer for the hygienic emptying of collected solids without direct contact with them. State of the art

[0002] Drain strainers are known from the prior art. For example, DE 20 2021 004 315 U1 describes a drain strainer comprising a circular sieve with a multitude of openings in the form of a grid made of a flexible material, wherein the individual grid bars are 0.5 mm to 1.5 mm wide and the grid has a central opening. A flexible handle for manual positioning and lifting of the drain strainer is also provided on the grid. While such drain strainers, as known from the prior art, do allow for the collection of solids, cleaning them requires direct hand contact or the use of separate tools, which is considered unhygienic. Description of the invention

[0003] The present invention therefore aims to eliminate the aforementioned disadvantages and to provide a drain strainer that enables hygienic emptying of the collected solids without requiring direct contact with them or the use of additional tools, and which is also easy to clean and, in particular, dishwasher-safe.

[0004] According to the invention, the aforementioned problem is solved in accordance with the preamble of claim 1 in conjunction with the characterizing features. Advantageous embodiments and further developments of the drain strainer according to the invention are specified in the dependent claims.

[0005] The drain strainer according to the invention comprises a circular strainer basket with a screen surface having a plurality of through-openings, further comprising a side wall that at least partially surrounds the screen surface and a rigid handle for manual positioning and lifting of the drain strainer according to the invention. The screen surface is dimensioned such that liquids can flow away unhindered, while solids are retained.

[0006] The present drain strainer is characterized by the fact that at least one elongated cleaning opening, aligned parallel to the strainer surface, is formed in the side wall of the strainer basket.

[0007] The advantage of a drain strainer with a cleaning opening in the side wall is that accumulated residue such as hair or dirt can be removed much more easily. This simplifies cleaning, reduces the formation of deposits and blockages in the drain, and improves flow rate. Furthermore, the opening allows for more hygienic handling and contributes to a longer lifespan and overall lower maintenance of the drain strainer. This design also enables hygienic disposal of collected solids without the user having to come into contact with them. Cleaning effort is reduced, and the strainer's usability is increased.

[0008] The drain strainer can be made of plastic, metal, biodegradable materials or other suitable materials and is preferably dishwasher safe.

[0009] The cleaning opening is preferably designed and arranged in such a way that it does not significantly impair the function of the drain strainer – the retention of solids – during normal operation, but allows for targeted cleaning. Brief description of the drawings

[0010] Further objectives, features, advantages and application possibilities of the drain sieve according to the invention will become apparent from the following description of an exemplary embodiment with reference to the drawings.

[0011] The drawings show Fig. 1 the drain strainer according to the invention with a cleaning device in an advantageous embodiment in perspective view; Fig. 2a-2d different views of the drain strainer; Fig. 3. The cleaning equipment in perspective view. Implementation of the invention

[0012] As from Fig. As can be seen in Figure 1, the cleaning opening 14 extends from level 150.1 of the screen surface 150 preferably towards the upper edge 151.1 of the side wall 151. The advantage of a cleaning opening 14 extending from the screen surface 150 towards the upper edge 151.1 of the side wall 151 is that dirt and residue can be easily removed or rinsed away from the entire lateral area. This prevents dirt from accumulating at the transition between the screen surface 150 and the side wall 151 – an area that is often difficult to access with conventional drain strainers. Furthermore, water can drain more easily through the opening during rinsing or cleaning, which supports the self-cleaning of the drain strainer 10. Overall, this arrangement enables more thorough and easier cleaning, improves hygiene, and ensures a consistently unobstructed flow.

[0013] The cleaning opening 14 can preferably be slit-shaped, rectangular, oval and / or polygonal, although other designs are also possible.

[0014] As can be seen particularly from the Fig. As shown in Figure 2b, the width of the cleaning opening 14 preferably corresponds substantially to the width of the sieve surface 150. If the cleaning opening 14 covers almost the entire width of the sieve surface 150, it enables complete and uniform cleaning of the entire sieve area. This allows residues to be removed quickly and efficiently, hard-to-reach corners are avoided, deposits are reduced, and the overall hygiene of the drain sieve 10 is improved.

[0015] In a particularly advantageous embodiment of the invention, the drain strainer 10 comprises at least two cleaning openings 14 arranged opposite each other on the side wall 151. When the drain strainer 10 has at least two opposing cleaning openings 14, cleaning tools or devices that are pushed through the cleaning openings 14 can act on the strainer surface 150. This allows dirt to be loosened and removed particularly efficiently, since it does not have to be pushed away from only one side. Furthermore, cleaning becomes more uniform, operation simpler and faster, and hard-to-reach areas in the center of the strainer surface 150 can be easily accessed. Overall, this arrangement enables faster, more thorough, and more convenient cleaning. It is particularly advantageous if the cleaning openings 14 are arranged symmetrically to the central axis of the strainer basket 15.

[0016] As already described, the present invention further comprises a cleaning device 20 for such a drain sieve 10, wherein the cleaning device 20 has a handle 200 and a flat cleaning tool 201 connected to the handle 200, which is designed to be inserted into the cleaning opening 14 and guided along the sieve surface 150.

[0017] The cleaning tool 201 is preferably designed for positive-locking insertion into the cleaning opening 14.

[0018] Furthermore, the cleaning device 20 can be designed to be guided through both opposing cleaning openings 14, which contributes to the advantages already mentioned above.

[0019] Furthermore, the present invention includes a system consisting of a drain sieve 10 and a cleaning device 20. QUOTES INCLUDED IN THE DESCRIPTION
