Abstract
In a known manner, a shower head, particularly for a hand shower, has a bell-shaped housing, which is closed off at the bottom by a shower base (1) and in which at least one water chamber is formed which connects with a water supply channel. The shower base (1) contains a large number of water outlet openings (15), which are made on hose-type jet attachments (11). The hose-type jet attachments (11) extend from a smooth, unbroken, continuous outer surface of the shower base (1) which is free of indentations apart from the water outlet openings (15) into the inside of the housing. In so doing they pass through a hole (3) in the shower base (1), the diameter of which is larger than the outer diameter of the jet attachment (11). In this way, there is formed round the jet attachment (11) a clear circular space (13) which does not open in the outer surface of the shower base (1) but in its inner surface. As a result of this clear circular space (13), the jet attachments (11), which are not visible from the outside, can be flexed to dislodge limescale.
