Description :

The invention relates to an attachable to a water outlet of shower head with an adjusting device for jet two types according to the preamble of claim 1. Such shower heads are suitable for use in hand showers, or as a single shower heads for showers \

as well as for ceiling showers in a wide variety of designs

known. H

The invention assumes that it is inexpedient for shower heads with a sieve ring and an aerator is to form mixed states between these two different types of water outlets, because in particular When the shower head is inclined, the "soft" water jet emerging from the aerator flows through the outer

The invention is therefore based on the object of making available a shower head of the type mentioned at the beginning with a simple design with fewer components, which has an adjusting device which enables an exact changeover from one spray pattern to the other.

Adjustment process to take advantage of changing dynamic pressure. By using eir.es by means of spring-loaded valve member lä ^a t the effort involved to reduce designed components, especially the valve member itself is formed very easily and the spring may be commercially available. The use of susceptible sealing rings is also minimized in the invention, which plays a significant role in particular in the case of sealing rings that are exposed to abrasive forces. In the case of the shower head according to the invention, it is sufficient to achieve the sealing of the inflow channel to the screen rim by supporting simple sealing surfaces, in particular on plastic parts.

The shower head with adjusting device according to the invention can consist of a few parts, namely from the with the water outlet connectable sleeve, the rotating body, the valve element and a commercially available aerator (Perlator) and a - also commercially available - spring, because according to further proposals of the invention, the spring can be designed as a helical compression spring, which is expediently with one hand on the aerator or sieve and is supported with its other end on the valve member, and because the screen rim is integral and cohesive with the Rotary body can be formed and also the counter seal cooperating with the seal of the sleeve as well an adjustment thread in one piece and cohesively with the Sieve ring can be formed.

According to a further inventive feature is It is advantageous if the valve member can be placed with a conical section on the edges of the water passage opening

is and with a collar portion on the end of the helical compression spring sits on.

The essential features of the invention described above show that the aerator, which is also against you Sieve insert can be exchanged, which has a different hole pattern compared to the sieve ring, in a multi-function rotating body can be fastened, which also forms the housing for the spring-loaded valve member.

The invention is explained in greater detail below with reference to an exemplary embodiment shown in the drawing explained. The drawing shows a shower head according to the invention as part of a hand shower, wherein in the left part of the figure the open flow through the sieve ring with the inlet to the aerator closed is shown and blocked in the right half of the inflow to the sieve ring and the open to the aerator is shown.

. The shower head is designated by 10 in its entirety. It consists of a sleeve 11, a rotating body 12, an aerator (aerator) 13 or a sieve insert and a valve element 14, between which and the aerator 13 a spring 15 designed as a helical compression spring is clamped. The sleeve 11, the rotating body 12 and the valve member 14 are plastic injection molded parts in the exemplary embodiment, while the aerator 13 and the spring 15 are commercially available standard parts.

In the embodiment, the sleeve 11 is by means of a upper circumferential jCragens 16 by welding with the

End section 17 of a water outlet 18 designed as a handle is connected to the water inlet channel 19. Instead of the A screw connection is also possible. Of course, the shower head 10 can also be connected to a A water pipe that opens onto the wall or jacket is attached, e.g. screwed on.

In its end region facing away from the collar 16, the sleeve 11 has a recess or annular groove 20 into which a Sealing ring 21 made of rubber or other suitable sealing material is incorporated. This makes it radial Sealing ring 21 seated under tension is also axially fixed. He acts with a smooth inner surface 22 in a essential axially extending collar 23 of the rotating body 12 together. Has on its outer circumference Collar 23 recessed grips 24 or grooves that are easy to grip.

In the exemplary embodiment, the rotating body 12 not only has a one-piece and cohesive design the collar 25, but also a closing one at the bottom Sieve ring 25 with water outlet openings 26 arranged in circular rings, learns one further inside from Sieve ring 25 extending cup-shaped insert 27 with internal thread 28 for receiving the aerator 13, further a water passage opening that can be blocked by the valve member 14 29 to act on the aerator 13 and finally a collar 30 with an external thread at the end 31, which has an internal thread 32 of the sleeve 11, which has a main water inlet opening 33 on the outside cooperates.

If the adjusting thread 31/32 consisting of the external thread 31 and the internal thread is executed right-handed, then it can be seen that when the rotating body 12 is rotated to the right, it moves upwards with respect to the drawing, that is to say from its Position in the left half of the drawing to that shown in the right part of the figure.

When the rotating body 12 is unscrewed, as shown on the left, one consists of a sealing surface 34 Seal the sleeve 11 from a peripheral edge 35 formed counter seal lifted, whereby an annular inlet 36 to the screen ring 25 for the water flow is released. The water penetrates from the water inlet channel 19 through the main water inlet opening 33 and a peripherally opening water inlet opening 37 which, with the inclusion of stabilizing webs can be designed circumferentially, and then reaches the inlet 36 and the annular space 38 to the water outlet openings 26 of the sieve ring 25.

In this first described operating position, in an annular jet pattern with water exiting through the water exit openings 26 of the screen ring is present alone, is the valve member 14 with its cone portion 39 due to the relatively low Dynamic pressure on a circumferential edge 40 of the water passage opening 29 of the rotating body 12, as it is in

left part of the drawing is shown. If now the rotating body 12 - clockwise with a right-hand thread - upwards screwed, so lay - see right part of the figure, seal 34 and counter-seal 35 on top of one another, whereby the

Water flow to the annular space 38 is blocked so that no more water through the water outlet openings 26 of the Sieve ring 25 can pass. By blocking the inlet 36, there occurs in the space in front of the valve element 14 a dynamic pressure, which is the from the spring 15 on the valve member 14, which with an annular collar portion 41 on the top rests on the spring, exceeds the pressure exerted. As a result, the valve member 14 is pressed down and gives - as shown in the right half of the figure Viasser passage opening 29 to aerator 13 free, through which now only the water supplied through the water inlet channel 19 emerges.

As a result of the dynamic pressure-controlled adjustment device a safe and reliable reversal from one spray pattern to another is guaranteed at all times. As a result, a soft, narrowly delimited jet can either be set or via the aerator 13 via the water outlet opening arranged in a circular ring. 2b of the screen ring 25 has a plurality of hard jets. The mixed state that is detrimental to a clean spray pattern is avoided due to the inventive design. In addition, the shower head according to the invention is in particular with regard to its sealing arrangements very simply designed and therefore also reliable in its function. The components used are small in number and simple in design.

The simplicity should also be emphasized in particular the sealing of the aerator or sieve inlet

by the spring-loaded valve member 14. Thanks to the conical outer surface of the valve member is not just a simple one Sealing is possible through its contact with the circumferential edge 40 of the water passage opening 29, but rather always achieved an absolute tightness of this seal in the blocked state, because the valve member 14 only over the fender 15 is turned over and thereby compensating tilting movements can perform for self-centering.
