Description

The present invention relates to a suction device for the extraction of liquid media and in particular of water, in particular from stagnant water, in particular swimming pools, swimming ponds and the like. From the prior art, such suction devices, commonly referred to as skimmers, have long been known. These are usually arranged at an upper area of a swimming pool or swimming pond and serve to suck water from the surface and in particular to filter out dirt residues from this water. For this purpose, such suction devices usually have a pivotable float element, over which sweeps the inflowing water. In addition, these elements often have interior filter elements such as coarse or fine filters for filtering debris, such as leaves. Especially with swimming ponds with frequent soiling, however, it can happen that these filter elements clog. In this case, an overflow of the respective water can occur. In addition, often in the region of an input channel of such devices can lead to jamming of larger elements, which can also lead to malfunction in further operation.

The present invention is therefore based on the object to prevent the risk of such overflow. In addition, the causes that can lead to such an overflow, can be easily resolved. These objects are achieved according to the invention by the subject matters of the independent claims. Advantageous embodiments and further developments are the subject of the dependent claims.
