Abstract

The shower base (1) of a shower head consists of a rigid perforated plate (1a), which has a number of holes (4, 5). Set inside each of the holes (4, 5) in the perforated plate (1a) is a hose-type jet insert (6, 8) made of a flexible material which, owing to its material properties, can be automatically flexed to dislodge limescale deposits. The shower base (1) is sealed against the rest of the shower head, in particular against its housing (2) by means of one or more seals (25, 29). This/these seal(s) (25, 29) is/are made of the same material as the jet inserts (6, 8) and is/are manufactured jointly with these, for preference connected in one piece. In this way, it is not necessary for the seals (25, 29) to be manufactured, kept in store and assembled separately.

Claims

1. A shower head, comprising:

a) an essentially bell-shaped housing in which at least one water chamber is formed which can be linked with a water supply channel;

b) a shower base, which seals a bottom of the bell-shaped housing and consists of

(ba) a perforated plate made of a rigid material which has a number of holes,

(bc) a number of hose-type jet inserts which are made of a relatively soft, flexible material, each of which have a jet channel terminating in a water outlet opening passing through them and each of which passes through a hole in the perforated plate; and

(c) at least one seal which seals the shower base against the housing, and at least one jet insert set in the housing,

wherein the at least one seal is manufactured jointly with the at least one jet insert and is made of the same material,

wherein the at least one seal is joined to a corresponding jet insert to form a single component, and

wherein the at least one seal is connected to the corresponding jet insert by at least one lug which extends along an inner surface of the perforated plate.

2. The shower head according to claim 1, wherein:

the lug is set in a groove molded in the inner surface of the perforated plate.

3. The shower head according to claim 1, wherein:

the at least one jet insert is formed in one piece with an impact protection plate which essentially covers the entire outer surface of the perforated plate and is made of the same material as the at least one jet insert.

4. The shower head according to claim 3, wherein:

the at least one seal is connected to the impact protection plate by at least one lug which extends through a hole in the perforated plate.

5. The shower head according to claim 1, wherein:

the at least one seal has the form of a ring seal and several lugs are provided which are spaced around a circumference of the seal.
