DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a shower spray with a venturi nozzle for the admixture of ingredients from a reservoir and ambient air to the water stream.
Nowadays, in addition to the conventional baths, showers are used widely in the private sector and in public establishments as devices for cleaning and/or massaging and therapeutic-treatment purposes. Apart from in special designs, a spray head with a large number of nozzle openings is provided, a fanned-out, finely distributed water jet emerging from this spray head. Depending on the type of nozzle openings, it is possible to draw a distinction between various showers as spray showers or rain-effect showers, fanned-stream showers or jet-stream showers. Furthermore, depending on the type of installation, it is possible to categorise the showers as fixedly arranged stand-up showers--in which case the shower head can be aligned if need be--and hand-held showers which can be moved freely on a flexible hose. It is the hand-held showers provided for spray action, in particular, which form the subject matter of the present invention. In general, a shower spray serves solely for fine, spray-like distribution of the shower water supplied.
However, shower sprays in which ingredients are admixed as washing, hair-care or body-care products--to the shower water from an externally arranged container are already known. U.S. Pat. No. 2,562,415 discloses a device in which a partial stream, which is branched off from the main-water stream before entering into the shower head, is directed through a container with bath salts and, once enriched with dissolved salts, is supplied back to the main stream. U.S. Pat. No. 2,316,781 and U.S. Pat. No. 3,231,200 describe devices with a liquid additive in the respective container, this additive being drawn off by the suction action of a venturi nozzle and admixed to the shower water. U.S. Pat. No. 3,720,352 and U.S. Pat. No. 4,200,206 disclose devices for the admixture of various liquid additives stored in a multi-chamber system, in which case, depending on valve actuation, one of the additives or a composition of a plurality of additives is admixed to the shower water. U.S. Pat. No. 4,019,658 presents a device in which the additive is taken from two aerosol cans introduced into the device. The publications mentioned above all relate to devices in which it is exclusively the additive which is admixed to the shower water.
In order to improve the mixing between the water jet and the additives, to render consumption more economical and, at the same time, to give the shower jet an invigorating tingling action, provision has been made of various devices in which, in addition to the liquid additives, a considerable quantity of air has also been supplied to the shower water. Both the additive and the air are taken in by a venturi nozzle arranged upstream of the shower head. Such devices have been disclosed by U.S. Pat. No. 2,743,913, U.S. Pat. No. 4,322,036 and U.S. Pat. No. 5,071,070, the latter publication involving a multi-chamber system. The common feature of all these devices is that they require one or more containers arranged externally to the shower spray for the purpose of storing the additives, and thus it is only stand-up showers which are actually suitable for being fitted out in such a manner. Activation of the admixture operation is somewhat complicated since it is necessary to actuate the mechanism of the admixture device separately from the cold-water and hot-water valves or the combination valve, and at some distance from the latter. In addition, the relatively voluminous containers for the additives do not always lend themselves to aesthetically pleasing integration in an, at best, only medium-sized bathroom. Moreover--as a result of the additive being flushed directly into the shower jet--an effective distribution of fragrance is only possible with a substantial admixture of the additive, but this causes not inconsiderable contamination of the waste water. Finally, the abovementioned devices cause a considerable amount
