Abstract: A WC device with a WC body and a flushing water supply device for supplying flush water to the toilet body. The flush water supply device is provided with a water connection for drinking water for use as flush water. The WC body has a bowl-shaped WC body section and a subsequent odor trap. The bowl-shaped WC body section has a porous inner surface which is connected to a device for supplying cleaning fluid for keeping the porous inner surface clean. The flushing water supply device is provided with at least one back-suction safety device, which prevents back-suction of cleaning liquid from the porous inner surface to the water connection. Thus, the WC device completely or at least largely prevents excrement or dirt residues from adhering to the inner surface of the WC body, and the back-suction safety device provides hygienically flawless protection on the drinking water side.
