Toilet bowl washing system

The invention relates to a washing system for a toilet bowl. Some existing toilet bowl washing systems do not sufficiently clean the toilet bowl. The invention aims to provide a toilet bowl washing system where water is provided to reach the desired parts easily by enabling water from a clean water channel to progress and flow on both right and left sides laterally as well as downwards into the toilet bowl. The washing system is mounted on a sanitary ware product to wash the toilet bowl. The system comprises an inner body part having a side channel positioned on the right and left sides of the inner body part. It is the inner body part that provides water from the clean water channel to flow into the toilet bowl from right and left directions. At least one channel in the middle part provides water to flow directly downwards into the toilet bowl. The system has at least one sealing element installed into the inner body and a cover installed on the inner body. The system also has an outer body part which is to be installed on the sanitary ware product. The inner body is installed in the outer body. A fixing part fits the outer body part to the sanitary ware product. Fixing screws fix the outer body to the sanitary ware product by tightening the fixing part. The system has at least one sealing element providing impermeability between the sanitary ware product and the outer body.
