Description

Artichoke.

The invention relates to an artichoke for produce pulsating shower jets, especially for massage with water, with at least one annular channel that has openings for the water outlet, channel in which a body of closure for water outlet openings, where water from the shower enters the annular channel tangentially or so inclined with respect to the axis of circulation, so that the body Closing circulates in the annular canal.

An EP 0 308 693 A1 is known as a shower system of this type. This system is intended as closing body a shuttle that covers at the same time three mouths water outlet and is slidably arranged inside the annular channel The sliding support of the shuttle requires, without However, a relatively large drive energy that could increase correspondingly as the water outlets to cover at the same time, to get that the closing body circulates inside the annular channel and keep it So. On the other hand, a better pulsation effect can be achieved of the shower jets for a simultaneous closure of the largest possible amount of water outlets.

US 3762648 discloses an artichoke to generate pulsating shower jets by means of a rotor of valve that is rotated by water. For the rotor of valve can be provided a shaft support and a bearing of balls.

The object of the invention is to provide a smooth and circulating closing body with little wear to cover several outlets at the same time Water.

This objective is achieved according to the invention with the characteristics of claim 1.

Other configurations of the invention are They are indicated in claims 2 to 10.

With the closing body according to the invention it is possible to reduce friction resistance considerably by the arrangement of rolling elements so that the body of closure can be sized so that it can be covered simultaneously a greater number of water outlets.

It has been advantageous that the closing body cover approximately one third to one quarter of the mouths of water outlet

In another configuration of the invention, the body closure can be conveniently arranged in a ring that It can be inserted in the annular canal, where in the area of the ring have advantageously made three symmetrical cages for the accommodation of three rolling elements. The elements rolling wheels can advantageously have a spherical design or conical.

The ring can be conveniently manufactured with the closing body and the cages in a single piece of material synthetic by the transfer molding process, where the closure body is arranged in the ring so that it is maintained by the rolling elements within the annular channel with a Small strike with respect to the artichoke bottom of the annular canal.

In another configuration of the invention also they can provide for two or several annular arrangement channels concentric, in which the stopper bodies can be arranged corresponding circulating independent of each other, where as alternatives you can also use a closing body that covers simultaneously several water outlets and, on the other hand, a circulating sphere as a closing body that covers during a a water outlet is short lasting in each case. The connection of the different annular channels of concentric arrangement are performs here, advantageously, through conductive nozzles that direct the incoming water tangentially before the Entry into the next annular channel.

Naturally, the plug bodies according to the invention with the annular channel configuration can also be arrange in an artichoke in which other systems are planned of generating shower jets, for example one or more devices for generating non-pulsating shower jets. Here the Incoming shower water in each case can be conducted towards the desired jet generation system by means of a valve investment to anticipate.

In the drawings, examples of embodiment of the invention which are described in more detail at continuation. The drawings show:

- Figure 7: a part of the artichoke background represented in figure 6, by the plane of section VII.

To simplify, in the execution examples of the drawings, the same elements or corresponding elements they carry in each case the same reference. In the hand shower shown in figures 1 to 3 a head housing is provided of shower 1 of approximately coupled form, in which laterally a handle 10 is partially shown. In the housing from the shower head 1 a plate 11 is first provided fixedly arranged against rotation and sealed with an O-ring, plate on which the central axis is eccentrically provided 13 a passage opening 110 for the incoming shower water. The housing shower head 1, open downstream, is closed with a artichoke bottom 2. Here, artichoke background 2 can be rotated by means of a central screw 12 axially with respect to the housing shower head 1, but fixed axially, where a 23 circular collar formed on the bottom of artichoke 2 wraps the shower head housing 1 with a ring seal toric

At the bottom of artichoke 2, on the side located upstream, it has been fixed tightly and fixed against the I turn a water conducting body 25. The water conducting body 25 it is provided with an inlet opening 250 of eccentric design corresponding to the passage opening 110 and an O-ring 253 that surrounds the inlet opening 250 on the front surface of so that in the turning position shown in figure 1 the water Shower flows from the passage opening 110 into the opening input 250 of the water conducting body 25 and penetrates into an annular space 252 inside. If, on the contrary, it is rotated 180º on artichoke bottom 2 with water conducting body 25, as has been shown in figure 3, the inlet opening 250 is closed by means of the plate 11 while the shower water penetrates to through the passage opening 110 in an outer annular space 251 from the bottom of artichoke 2.

The outer annular space 251 is connected downstream with a ring of water outlet openings 20 with which can generate continuous non-pulsating water jets. He inner annular space 252 is connected with two annular channels 21 of concentric arrangement through conductive nozzles 22. In the two annular channels 21 a row is provided in each case of water outlet openings 20 arranged in a circle and that pass through the bottom of artichoke 2, openings that partially closed by means of a closing body 3 that circulates with the incoming water inside the annular channel 21 so that it they produce pulsating jets at the shower outlet.

In the outer annular channel 21 the body of closure 3 is integrated in a ring 30 with a cross section considerably less than it releases the water outlet openings. The closure body 3 is sized here so that it covers approximately one third of the total number of exit openings of water 20 at the bottom of artichoke 2 of the annular channel 21. Also, in the ring 30 has formed three disposition cages 31 symmetric that serve for the accommodation in each case of an element Rolling 4 built as a sphere. The closing body 3 has been performed here along with ring 30 and the three cages 31 in one single piece of synthetic material by transfer molding. The 4 rolling elements configured as spheres are conducted here in the annular channel 21 in a groove 210 made in the bottom of artichoke 2.

In the inner annular channel 21 it has been arranged as a closing body only one sphere. Naturally without However, an inner channel 21 can also provide a closure body with a smaller diameter designed in accordance with the outer ring channel.

The hand shower, described above, works from following mode:

The shower water is fed by a pipe flexible not shown in the drawing to the handle 10 of the shower partially represented hand.

In the arrangement of artichoke bottom 2 with relation to the shower head housing 1 represented in the Figure 1 the inlet opening 250 of the water conducting body 25 coincides with the passage opening 110 of the plate 11, so that the incoming shower water penetrates into the annular space 252 inside. As you can see, especially in figure 2, water of shower that is in the annular space 252 is fed tangentially to the outer annular channel 21 by means of a nozzle conductive 22, due to which the water flow in the channel annular 21 causes the ring 30 to rotate with the three cages 31 that they act as blades in the water stream, and with the body of closure 3. The circulating closure body 3 covers in each case a third of the water outlets 20 or interrupts the passage of water so that pulsating shower jets are generated circulating

In addition, shower water penetrates the canal inner ring 21 through the conductive nozzles 22, located inside, and due to the tangential input of the current also causes the closing body 3 to rotate so that also in the annular channel 21 they close temporarily, so circulating, water outlets 20.

By covering or closing circulatingly the different water outlets 20 pulsating jets are generated shower Unlike a rotating ball as a closing body 3, which closes a single water outlet for only a short moment, with the closing body 3 according to the invention, the different water outlets 20 can close during a longer time The closing time depends here on the size of the closing body 3 that covers. The effect of the pulsating jets of Water can be adjusted as desired by the parameters: pressure of water, water flow, closing body size and number and size of water outlets.

In the position shown in Figure 3, it has rotated 180º the bottom of artichoke 2 with respect to the housing of the artichoke 1 in order to change. In this position of rotation the plate 11 closes the entrance opening 250. The passage opening 110 is connected here with the outer annular space 251. The shower water which penetrates the annular space 251 is supplied in the form of constant, non-pulsating shower jets, through the circle of water outlets 20 provided at the bottom of the artichoke.

The example of execution shown in the figures 4 and 5 differs from those described above essentially because only one annular channel 21 has been formed, and in the background of artichoke 2 of annular channel 21 two circles of concentric arrangement of water outlets. The body of closure 3 is designed here so that it covers a third of the two circles of water outlets, and said closure body 3 it is provided with two rings 30 on the inner side and the side exterior in which three disposition cages 31 are planned symmetric for rolling elements 4. Rolling elements 4 they have a conical design here, so you can suppress the circular grooves in the bottom of artichoke 2. Otherwise, this Execution example corresponds to the previous one.

Another example of execution of an artichoke bottom 2 without an artichoke shell. In this arrangement, the annular channel 21 is provided in the area outside of artichoke background 2, while in the central zone two circles of water outlets 20 have been formed since which can be supplied with constant shower jets, not pulsating The closure body 3 covers here, too, approximately one third of water outlets 20 arranged in a circle Here the closing body 3 is driven gently again by three rolling elements 4 spherical, and in the closure body 3 has formed, on the inner side, a ring 30 of minor cross section in which they have been shaped three cages 31 of symmetrical arrangement for rolling elements 4. The rolling elements 4 are driven here by a groove 210 at the bottom of artichoke 2. In addition to the tangential feeding of the incoming shower water in annular channel 21, this can also be carried out by one or several inclined nozzles with respect to the central axis of the artichoke housing 1.

To get a smooth twist and a good effect of closure of closure body 3 the latter is arranged conveniently with a small clearance 32 relative to the bottom of artichoke 2 of the annular channel 21.
