Description

[0001] The invention relates to a shower head, in particular a sanitary shower head, with a base body having at least one shower fluid inlet. The shower head also has a spray disc unit located on a shower jet outlet side of the base body, which has several fluid outlet units, each of which has a fluid outlet opening, a nozzle interior, and at least one inlet opening into the nozzle interior. The shower head further comprises at least one first fluid connection and a fluid-separated second fluid connection, each from the at least one shower fluid inlet to the fluid outlet units. A cavity is formed, bounded by a chamber floor and a chamber ceiling, which is divided into several laterally separated fluid chambers by a fluid-tight partition structure between the chamber floor and the chamber ceiling.Furthermore, a first fluid chamber of the fluid chambers is part of the first fluid connection and a second fluid chamber of the fluid chambers is part of the second fluid connection.

[0002] Shower heads of this type are typically used to deliver a shower fluid with a choice of different spray patterns and / or fluid volumes. These types of shower heads are particularly common in bathrooms, for example as hand showers, side showers, or overhead showers, where water usually serves as the shower fluid. However, these shower heads are equally suitable for non-bathroom shower applications where any fluid is to be delivered as a spray. Alternatively, they can also be used as part of a kitchen or bathroom faucet.

[0003] For shower heads with different spray patterns, it is common practice to arrange the corresponding fluid connections on different planes, i.e., one above the other when viewed from the spray direction. However, this requires a correspondingly large shower head height and results in a relatively high amount of residual water in the shower head after it is switched off, which in turn can promote unwanted dripping. Furthermore, such shower heads often have several groups of fluid outlet openings, which are supplied with fluid depending on the desired spray pattern, so that, as a rule, only some of the fluid outlet openings are actually emitting a fluid spray during operation. Additionally, when switching between groups of fluid outlet openings, unwanted dripping occurs at the currently used group.

[0004] The invention is based on the technical problem of providing a shower head of the type mentioned above, which offers advantages over the prior art in particular with regard to its shower jet delivery functionality or jet performance, its construction with relatively few components, relatively low manufacturing costs, a compact, flat design, low dripping time and low water consumption and / or its shower jet adjustment characteristics.

[0005] The invention solves this problem by providing a shower head with the features of claim 1. Advantageous embodiments of the invention are specified in the dependent claims, the wording of which is hereby incorporated into the description by reference. This includes, in particular, all embodiments of the invention resulting from the combinations of features defined by the cross-references in the dependent claims.

[0006] In the shower head according to the invention, the fluid outlet units are each fluid-connected to the at least one shower fluid inlet via both the first fluid connection and the second fluid connection. Furthermore, a first inlet opening of each fluid outlet unit opens at least substantially centrally into the nozzle interior, and a second inlet opening of each fluid outlet unit opens tangentially into the nozzle interior.

[0007] With a central flow into the nozzle interior, it is advantageous for the fluid to flow from the inlet opening in the direction of a longitudinal axis of the fluid outlet opening.

[0008] With a tangential flow into the nozzle interior, the fluid can advantageously flow from the inlet opening, particularly along an inner wall of the fluid outlet unit, around the longitudinal axis of the fluid outlet opening, especially in a swirling motion towards the fluid outlet opening. In other words, with a tangential flow, the fluid enters the nozzle interior off-center.

[0009] By varying and adjusting the fluid flow into the nozzle interior of the fluid outlet units—namely centrally and / or tangentially—different and adjustable fluid jets can be generated from the same fluid outlet units or fluid outlet openings. It is therefore possible to generate both normal, straight fluid jets and finely atomized or conical fluid mist jets from the same fluid outlet openings. Additionally, fluid mixing jets are also possible, combining the two aforementioned fluid jet types.

[0010] Furthermore, it is possible, for example, to supply one of the two fluid connections with hot water and the other with cold water; that is, the fluid temperatures in the two connections can be different. Various other fluid jet patterns can be set by adjusting the fluid temperature.

[0011] In a further development of the invention, the fluid outlet units are designed to generate a simple, straight fluid jet in the case of a central flow through the first inlet opening and to generate a conical fluid jet, in particular in the form of a fine spray mist, in the case of a tangential flow through the second inlet opening.

[0012] In a functionally and structurally advantageous embodiment, the fluid outlet units are designed to generate a fluid mixing jet when flow occurs simultaneously through the first inlet opening and the second inlet opening, i.e., a conical droplet-shaped fluid jet emerges from one fluid outlet opening.

[0013] In a further development of the invention, the two inlet openings of a fluid outlet unit are arranged on opposite sides of the nozzle interior. This represents a structurally and functionally advantageous implementation of a fluid supply to several fluid outlet units by means of two fluid-tight, mutually separated fluid connections.

[0014] In a further development of the invention, a first entry direction of the first inlet opening into the nozzle interior and a second entry direction of the second inlet opening into the nozzle interior are aligned parallel to each other. This represents a structurally and functionally advantageous implementation for the different types of fluid jets, particularly with regard to their jet performance.

[0015] In certain configurations, the first inlet opening opens from a first supply channel as part of the first fluid connection, and the second inlet opening opens from a second supply channel as part of the second fluid connection. The two supply channels are aligned parallel to each other. Advantageously, the two supply channels are arranged in a common plane within the jet disc unit.

[0016] In a further development of the invention, the first fluid chamber and the second fluid chamber are arranged in a common plane of the spray disc unit, in particular in a plane perpendicular to a shower jet exit direction. The common plane is preferably essentially parallel to the chamber ceiling, which facilitates achieving a very flat design for the shower head.

[0017] In a further development of the invention, the two inlet openings of one, in particular each, fluid outlet unit are located in a common plane, in particular in a plane perpendicular to the direction of the shower jet outlet.

[0018] In an alternative design, the two inlet openings of a, in particular each, fluid outlet unit are located on different planes.

[0019] In a further development of the invention, the nozzle interior has a round, in particular circular, or oval cross-section. Preferably, the cross-section is oriented perpendicular to the direction of the shower jet exit.

[0020] Additionally or alternatively, the nozzle interior is at least partially conical and tapers in the direction of the shower jet exit, i.e., the cross-section of the nozzle interior decreases from the inlet openings towards the fluid outlet opening.

[0021] In certain designs, the nozzle interior can be at least partially hemispherical or funnel-shaped and can also taper in the direction of the shower jet exit.

[0022] In a further development of the invention, the first fluid chamber is part of the first fluid connection and the second fluid chamber is part of the second fluid connection. The first fluid chamber has at least one first main channel extending from an inlet into the first fluid chamber and at least two first branch channels extending from the first main channel. The second fluid chamber also has at least one second main channel extending from an inlet into the second fluid chamber and at least two second branch channels extending from the second main channel.

[0023] This configuration, with its specific arrangement of main and branch channels, offers several advantages regarding the shower head's design and construction, as well as its spray pattern functionality. This particular arrangement allows for a low-profile shower head, which can be desirable for aesthetic reasons. Furthermore, it minimizes residual water in the shower head body after it is turned off, thus reducing dripping time. The reduced number of components also makes the shower head simple and cost-effective to manufacture.

[0024] In one embodiment of the invention, the main channels, the branch channels and the inlet openings of each fluid outlet unit lie in a common plane.

[0025] In a further development of the invention, the chamber floor has a rigid projection structure on its side facing the chamber ceiling. This rigid projection structure interacts with the chamber ceiling to form the partition structure. This represents a structurally and functionally advantageous realization of a fluid-tight separation of the cavity in the base body into several laterally separated fluid chambers. The projection structure has a chamber-forming function, is preferably designed essentially vertically to the chamber floor, abuts the chamber ceiling in a fluid-tight manner, and forms the partition structure. In an alternative embodiment, the chamber ceiling has a rigid projection structure on its side facing the chamber floor, which interacts with the chamber floor to form the partition structure.In another alternative embodiment, both the chamber floor on its side facing the chamber ceiling and the chamber ceiling on its side facing the chamber floor each have a rigid projection structure, with the two projection structures forming the partition structure. In corresponding embodiments, the projection structure is formed integrally on the chamber floor and / or the chamber ceiling, depending on the specific design. The chamber floor and the chamber ceiling are preferably formed on separate components that are detachably connected to each other during assembly of the shower head.

[0026] In an alternative embodiment, a rigid insert structure is arranged in the base body between the chamber floor and the chamber ceiling. This insert structure interacts with the chamber floor and ceiling to form the partition wall structure. The insert structure serves a chamber-forming function, is preferably designed essentially vertically to the chamber floor and ceiling, and forms a fluid-tight seal against both. The insert structure is a separate component, independent of the chamber ceiling and floor, and is inserted between them. Therefore, its material can be selected independently of these components.

[0027] In a further development of the invention, the chamber floor is formed as a rigid plate made of a rigid material, and the chamber ceiling is formed as an elastomeric plate, wherein the chamber floor has the rigid projection structure on its side facing the chamber ceiling. This creates an advantageous fluid-tight partition structure between the chamber floor and the chamber ceiling, in which the rigid projection structure provides the necessary strength and pressure stability, and the elastomeric plate provides the necessary sealing. In alternative embodiments, the chamber ceiling is formed as a rigid plate made of a rigid material, and the chamber floor is formed as an elastomeric plate, with the rigid projection structure in this case also being formed on the side facing the chamber floor.

[0028] In a further development of the invention, at least one, and in particular each, fluid outlet unit has a jet guidance device. The jet guidance device comprises an orbit arranged in the nozzle interior, extending annularly around the longitudinal axis of the fluid outlet opening, and a jet guidance unit arranged to be movable around the orbit, wherein the main jet direction of the fluid jet exiting the housing body through the jet outlet opening can change depending on the position of the jet guidance unit on the orbit. The jet guidance unit can have at least one jet guidance element moved around the orbit by the fluid pressure of the supplied fluid, which may be a rolling element, e.g., a roller, moving along the orbit.is designed in the form of a sphere, or as a sliding body gliding along the orbit, and at least on part of its orbit partially engages in an inlet cross-section of the beam exit opening in a beam-directing manner.

[0029] For example, a sphere positioned inside the nozzle can be used to generate movement or rotation of the sphere when the fluid outlet unit is approached tangentially, resulting in an oscillating fluid jet. Conversely, the jet guidance device can be designed such that no movement of the sphere occurs when the fluid outlet unit is approached centrally, resulting in a normal fluid jet.

[0030] In a further development of the invention, the shower head has a valve with a valve closing element, wherein the valve closing element is movably arranged in the base body between several setting positions and is designed to selectively shut off and release the first and / or the second fluid connection.

[0031] In an alternative design, the valve is located or installed outside the shower head.

[0032] In appropriate versions, the valve is equipped for a flow control function and the amount of fluid that can be conveyed via the first fluid connection and / or the second fluid connection is variably adjustable.

[0033] In one embodiment of the invention, the valve closing element, in a first setting position, opens the first fluid connection and closes the second fluid connection. In a second setting position, the valve closing element closes the first fluid connection and opens the second fluid connection. This represents a functionally reliable and easily manufactured implementation for the valve as a corresponding changeover valve.

[0034] In an alternative design, the valve closing element, in a corresponding setting position, either opens or closes both fluid connections simultaneously. In other designs, the valve closing element opens only one of the two fluid connections in the first setting position and opens both simultaneously in the second setting position. In this case, the valve closing element can, for example, close both fluid connections in a third setting position.

[0035] In a further development of the invention, the showerhead is a head shower, a hand shower, or a side shower, e.g., one for a sanitary shower unit. In an alternative embodiment, the showerhead is a kitchen shower.
