Abstract

A hand shower, for optional hard-jet and soft-jet operation in which the water paths provided for the hard-jet and soft-jet operations extend behind a change-over device completely separately from each other. In the water path associated with the soft-jet operation there is arranged a central device for enriching the through-flowing water with air, the area of which device is small compared to the entire outlet area of the water on the perforated plate of the shower. Both the water enriched with air and the water intended for the hard-jet operation are guided via a water distribution chamber; the two water distribution chambers communicate with two separate sets of outlet ports in the perforated plate of the shower (FIG. 4).

Claims

1. A shower provided with a housing, which terminates in a bell-shaped end part covered by a perforated plate, and with a change-over device for optional hard-jet or soft-jet operation and with a device which, in the soft-jet operation enriches the water with air,

(a) a water flow-diverting device (17;

117) that diverts the inflowing water to one of two completely separated water paths;

(b) each water path incuding a water distribution chamber (23, 35;

123,

     135) which covers areas which are substantially parallel to the portions of the perforated plate (8,

     108);

(c) each water distribution chamber (23, 35;

123,

     135) being in communication with a separate set of fluid outlet ports (31, 32;

131,

     132) in said perforated plate (8;

     108);

(d) a device (13;

     140) for enriching the water with air being arranged substantially centrally in the path of the water for the soft-jet operation at a point upstream of the soft-jet water distribution chamber (35;

     135) and occupies only a small area compared to the area of the perforated plate (8;

     108),

(e) a first of said two water distribution chambers (35;

     135) directly adjoining the perforated plate (8;

     108), and a second of said two water distribution chambers (23;

     123) being separated from the first water distribution chamber (35;

     135) by a chamber divider (10;

     110) and being located at a distance spaced from the perforated plate (8;

     108), and a plurality of flow sleeves (31;

     130) are provided which pass through the first water distribution chamber and establish a connection between said second water distribution chamber (23;

     123) and the outside of the perforated plate (8;

     108).

2. A shower as set forth in claim 1 wherein said flow sleeves (30;

130) are integrally formed with the chamber divider (10;

     110).

3. A shower as set forth in claim 1 wherein the flow sleeves (31;

130) project, with a free end, respectively into a hole (9;

     109) in the perforated plate (8;

     108), the diameter of the free end (31a) being smaller than the diameter of the hole (9;

     109) in the perforated plate (8;

     108) so that there comes about inside the hole (9;

     109) in the perforated plate (8;

     108) an annular clearance (32;

     132) via which water can emerge from the first water distribution chamber (35;

     135).

4. A shower as set forth in claim 2 wherein the flow sleeves (31;

130) project, with a free end, respectively into a hole (9;

     109) in the perforated plate (8;

     108), the diameter of the free end (31a) being smaller than the diameter of the hole (9;

109 in the perforated plate (8;

     108) so that there comes about inside the hole (9;

     109) in the perforated plate (8;

     108) an annular clearance (32;

     132) via which water can emerge from the first water distribution chamber (35;

     135).

5. A shower as set forth in claim 1 wherein the chamber divider (10) is supported on the perforated plate (8) via a centrally located annular wall (33) that is provided with several fluid passage ports (34).

6. A shower as set forth in claim 2 wherein the chamber divider (10) is supported on the perforated plate (80 via a centrally located annular wall (33) that is provided with several fluid passage ports (34).

7. A shower as set forth in claim 3 wherein the chamber divider (10) is supported on the perforated plate (8) via a centrally located annular wall (33) that is provided with several fluid passage ports (34).

8. A shower as set forth in claim 1 wherein the device (13;

140) for enriching the water with air is arranged in a hole (12;

     112) located in an insert (5;

     105) and communicates via a radial air suction channel (21;

     121) with an annular clearance (22;

     122) between said insert (5;

     105) and the housing (1;

     101), which clearance, is in communication with the outside atmosphere.

9. A shower as set forth in claim 8 wherein the device enriching the water with air is a standard air bubbler (13).

10. A shower as set forth in claim 9 wherein the air bubbler (13) is supported by a cylindrical collar (14) of the chamber divider (10) which projects into the hole (12) in the insert (5).

11. A shower as set forth in claim 8 wherein the device enriching the water with air is a perforated section (140) which passes through the hole (112) in the insert (105).

12. A shower as set forth in claim 11 wherein the perforated section (140) is integral with the insert (105).

13. A shower as set forth in claim 11 wherein a cylindrical collar (14) of the chamber divider (110) projects into the hole (112) in the insert (105) and ends a short distance from the perforated plate (140).
