Description

Cabeza de ducha.Shower head.

La invención se refiere a una cabeza de ducha, sobre todo para una ducha manual o instalada fija, con un cuerpo que está conectado a una toma de agua, y con una alcachofa, de material flexible, sujeta al cuerpo, donde la alcachofa presenta múltiples orificios para la salida del agua y se puede deformar mecánicamente para que se desprendan las incrustaciones de cal.The invention relates to a shower head, especially for a manual or fixed installed shower, with a body that it is connected to a water outlet, and with an artichoke, of material flexible, attached to the body, where the artichoke has multiple holes for water outlet and can be mechanically deformed so that the scale of lime is released.

Una cabeza de ducha de esta clase se conoce en el estado actual de la técnica por la patente EP-A-0 719 587. En ésta los orificios de salida del agua están conformados, al menos en parte, como prolongaciones tubulares de la alcachofa. Para permitir la deformación manual de las prolongaciones de la alcachofa, para que se desprendan las incrustaciones de cal, al menos una parte de las prolongaciones tubulares de la alcachofa está rodeada en una determinada zona axial de un espacio anular libre. Cabezas de ducha semejantes se conocen, en el estado actual de la técnica, en otras muchas realizaciones similares. Podemos mencionar aquí, por ejemplo, la patente WO 91/12894. Estas cabezas de ducha presentan en común el hecho de que la alcachofa presenta una construcción en forma de placa, y los orificios de salida del agua están formados por boquillas tubulares y de paredes delgadas. En la cabeza de ducha según la patente EP-A-0 435 031 se considera esencial que estas boquillas tubulares presenten una pared lo más delgada posible. De esta forma se podrán retirar a voluntad y con medios sencillos, mediante deformación, los depósitos de cal en el extremo de salida del agua de las boquillas. No obstante, aquí supone un inconveniente el que estas boquillas de paredes delgadas son muy sensibles a los daños, y en particular pueden sufrir daños por la deformación.A shower head of this class is known in the current state of the art by the patent EP-A-0 719 587. In this the water outlets are shaped, at least in part, as tubular extensions of the artichoke. To allow the manual deformation of artichoke extensions, so that lime scale detach, at least part of the tubular extensions of the artichoke is surrounded in a certain axial zone of a free annular space. Shower heads similar are known, in the current state of the art, in others Many similar embodiments. We can mention here, by example, WO 91/12894. These shower heads feature in common the fact that the artichoke presents a construction in plate shape, and water outlet holes are formed by tubular and thin-walled nozzles. On the head of shower according to patent EP-A-0 435 031 it is considered essential that these tubular nozzles present a wall as thin as possible. This way they can withdraw to will and with simple means, by deformation, the lime deposits at the outlet end of the water from the nozzles. However, here it is an inconvenience that these nozzles thin walls are very sensitive to damage, and in particular They can be damaged by deformation.

La invención tiene como objetivo crear una cabeza de ducha del tipo mencionado, que evite el inconveniente antes mencionado.The invention aims to create a head of shower of the mentioned type, which avoids the inconvenience before mentioned.

El objetivo se resuelve, en una cabeza de ducha de este tipo, con las características de la parte identificativa de la reivindicación 1. Una alcachofa anular de este tipo se puede deformar igualmente bien manualmente para eliminar las incrustaciones de cal, pero evita las paredes delgadas que podrían sufrir daños. Se evitan las inestabilidades en la formación del chorro, tal como aparecen en las prolongaciones tubulares de alcachofa conocidas. La alcachofa resulta especialmente apropiada para una cabeza de ducha que pueda alternar el funcionamiento como ducha con el funcionamiento en forma de chorro. El elemento para el funcionamiento en forma de chorro puede disponerse en posición céntrica respecto de la alcachofa. Si de acuerdo con un perfeccionamiento de la invención la alcachofa está provista de dos o más filas que discurren en sentido concéntrico, ésta resultará especialmente apropiada para una ducha de baño, que está provista de un número correspondientemente elevado de orificios de salida del agua. Entre las filas vecinas, en la alcachofa, aparecen formadas unas estrías o ranuras, que permiten la deformación de las diferentes filas. La ducha conforme a la invención se caracteriza por un tiempo de vida especialmente largo, y permite no obstante la mencionada eliminación por desprendimiento de las incrustaciones de cal.The goal is resolved, in a shower head of this type, with the characteristics of the identifying part of claim 1. An annular artichoke of this type can be deform equally well manually to eliminate lime inlay, but avoid thin walls that could suffer damage Instabilities in the formation of the jet, as they appear in the tubular extensions of known artichoke. The artichoke is especially appropriate for a shower head that can alternate operation as shower with jet operation. The element for the jet operation can be arranged in position Central to the artichoke. Yes according to a perfection of the invention the artichoke is provided with two or more rows that run concentrically, this will result especially suitable for a bath shower, which is provided with a correspondingly large number of exit holes of the Water. Between the neighboring rows, in the artichoke, they appear formed stretch marks or grooves, which allow deformation of the different rows The shower according to the invention is characterized for a particularly long lifetime, and nevertheless allows the mentioned removal by detachment of the encrustations of lime.

Otras características ventajosas se deducen de las reivindicaciones dependientes, de la siguiente descripción y del dibujo.Other advantageous features are deduced from the dependent claims, of the following description and of the drawing.

A continuación se describen con mayor detalle unos ejemplos de realización de la invención con ayuda de los dibujos. Las figuras muestran:They are described in more detail below. Examples of embodiment of the invention with the help of drawings. The figures show:

la Figura 1 una sección de una ducha según la invención,Figure 1 a section of a shower according to the invention,

la Figura 2 una vista de una alcachofa, yFigure 2 a view of an artichoke, and

la Figura 3 una sección de una alcachofa según una variante.Figure 3 a section of an artichoke according to a variant

La figura 1 muestra una cabeza de ducha 10 con un cuerpo 1, formado por una pieza de cuerpo 5 en forma de campana y el fondo de la ducha 6. Las dos piezas están atornilladas entre sí y estanqueizadas una frente a la otra mediante juntas 14 para la formación de una cámara para el agua 16. La cámara para el agua 16 está unida a un conducto de entrada de agua 15, que se conecta de forma conocida a una toma de agua no representada aquí. De manera concéntrica a la cámara para el agua 16 se encuentra otra cámara para el agua 17. Por medio de un mando 7 el conducto de entrada de agua 15 se puede comunicar a voluntad con la cámara para el agua 16 o con la cámara para el agua 17. En la posición indicada el conducto de entrada de agua 15 está en comunicación con la cámara para el agua 17. Si en la posición indicada el mando 7 se empuja hacia abajo contra la fuerza reactiva de un muelle de compresión 8, un dispositivo de cierre 10 unido a un émbolo 9 estanqueizado con una junta labial 13 se mueve desde el asiento de válvula superior 19 al asiento de válvula inferior 11, cerrando así la cámara para el agua 17 frente al conducto de entrada de agua 15. Se interrumpe así el acceso a la alcachofa 12, de por sí bien conocida y que por tanto no se describe aquí con mayor detalle, y el conducto de entrada de agua 15 se comunica con la cámara para el agua 16. El agua fluye ahora desde la cámara para el agua 16 hacia una alcachofa 2 elástica como el caucho, que va fijada en una ranura anular 4 del fondo de la ducha 6. La fijación se efectúa preferentemente mediante una unión a base de polímeros. Si se suelta el mando 7 el muelle de compresión 8 hace que el dispositivo de estanqueidad 10 vuelva a la posición que se muestra en la figura 1, en la que el agua sale como chorro a través de la alcachofa 12.No obstante, también resulta imaginable una realización en la cual el mando 7 se pueda retener en la posición inferior o que se mantenga en esta posición debido a una presión del agua superior a 0,5 bar.Figure 1 shows a shower head 10 with a body 1, formed by a bell-shaped body part 5 and the bottom of shower 6. The two pieces are bolted together and sealed against each other by means of joints 14 for formation of a chamber for water 16. The chamber for water 16 is connected to a water inlet conduit 15, which is connected from known way to a water outlet not shown here. By way of concentric to the chamber for water 16 is another chamber for water 17. By means of a control 7 the inlet duct of water 15 can be communicated at will with the water chamber 16 or with the water chamber 17. In the indicated position the water inlet duct 15 is in communication with the camera for water 17. If in the indicated position the knob 7 is pushed down against the reactive force of a compression spring 8, a closing device 10 attached to a piston 9 sealed with a lip seal 13 moves from the upper valve seat 19 to the lower valve seat 11, thus closing the chamber for water 17 in front of the water inlet duct 15. It is interrupted thus access to artichoke 12, in itself well known and that by both is not described here in greater detail, and the conduit of water inlet 15 communicates with the water chamber 16. The water now flows from the chamber for water 16 towards a 2 elastic artichoke like rubber, which is fixed in a groove annular 4 of the bottom of the shower 6. The fixing is carried out preferably by a polymer based bond. Whether release the control 7 the compression spring 8 makes the device sealing 10 return to the position shown in the figure 1, in which the water flows as a jet through the artichoke 12.No However, an embodiment in which the knob 7 can be held in the lower position or held in this position due to a water pressure greater than 0.5 Pub.

El elemento intermedio anular 2 está fabricado de un material elástico como el caucho, preferentemente con una dureza en el intervalo entre 40 y 80 Shore A, preferentemente en torno a 50 Shore A. Como muestra la figura 2, el elemento 2 presenta en sentido concéntrico dos filas A, B con varios orificios para la salida del agua 3. Según la figura 1 el elemento 2 está separado de la parte inferior 6a del fondo de la ducha 6, y se puede deformar en dirección radial hacia dentro y hacia fuera. De esta forma se sueltan las incrustaciones de cal en los orificios de salida del agua 3. La base 2a de la alcachofa 2 está sujeta en este caso en la ranura anular 4 del fondo de la ducha 6. La alcachofa 2 está preferentemente inyectada en el fondo de la ducha 6a y por tanto firmemente unida a éste. Esto permite una fabricación especialmente económica.The annular intermediate element 2 is made of an elastic material such as rubber, preferably with a hardness in the range between 40 and 80 Shore A, preferably around 50 Shore A. As Figure 2 shows, element 2 presents in the direction concentric two rows A, B with several holes for the exit of the water 3. According to figure 1 element 2 is separated from the part bottom 6a of the bottom of the shower 6, and can be deformed into radial direction in and out. This way you release the lime scale in the exit holes of the water 3. The base 2a of the artichoke 2 is held in this case in the annular groove 4 of the bottom of the shower 6. The artichoke 2 is preferably injected at the bottom of the shower 6a and therefore firmly attached to it. This allows a manufacturing especially economical

La figura 3 muestra una alcachofa en la cual están dispuestas tres filas A, B y C con orificios para la salida del agua 3. Entre cada dos filas vecinas A, B y B, C hay una ranura o estría 21 que permite la deformación de las filas vecinas. Esta alcachofa 20 está también inyectada en una ranura del fondo de la ducha 6. En la realización representada gráficamente están previstas tres filas A, B, C. No obstante, se pueden imaginar también realizaciones con dos filas o con más de tres filas. Esta alcachofa 20 resulta especialmente apropiada para una ducha de baño.Figure 3 shows an artichoke in which three rows A, B and C are arranged with holes for the exit of water 3. Between every two neighboring rows A, B and B, C there is a groove or stria 21 that allows the deformation of the neighboring rows. Is artichoke 20 is also injected into a groove in the bottom of the shower 6. In the embodiment shown graphically they are provided three rows A, B, C. However, you can imagine also realizations with two rows or with more than three rows. Is Artichoke 20 is especially suitable for a shower bath.
