(27) FIGS. 1 and 2a are respectively perspective and side views of a water distribution device 1 according to the invention, in the example a hand-held showerhead, intended to be connected to a flexible water supply pipe. The showerhead 1 comprises a body 10 of elongated shape. The body 10 is secured, at a first end, to a distribution head 12 comprising at least two groups of nozzles for ejecting a flow of water. In the example, the distribution head 12 comprises three groups of nozzles 14, 16, 18, each comprising a plurality of nozzles 14a, 16a, 18a arranged on a distribution face 12a of the distribution head. The body 10 comprises, at a second end opposite the first end, a connection device 10a making it possible to connect the distribution device 1 to a water supply pipe, and in particular to a flexible supply pipe. The connection device 10a makes it possible to connect a water supply pipe to at least one internal supply channel 10b arranged within the body 10, and visible in particular in FIG. 2a. The internal supply channel(s) make it possible to bring a flow of water to the different groups of nozzles 14, 16, 18 of the distribution device 1. A portion 10c of the body 10 forms a gripping handle. The distribution device 1 is configured to be attached to a wall support via a flexible pipe to which the distribution device is connected. Alternatively, the distribution device 1 can comprise, near the first end, a fixing part, allowing it to be fixed directly to a wall support.
(28) As visible in particular in FIG. 2a, which represents a partial section of the distribution device 1, each group of nozzles 14, 16, 18 is connected to at least one respective distribution channel 14b, 16b, 18b internal to the body 10 of the distribution device 1. In addition, a jet selection device 20 is interposed between the supply channel 10b and each of the distribution channels 14b, 16b, 18b. The selection device 20 comprises a movable internal body 20a, at least one portion of which is of spheroidal shape, and in particular of spherical shape, so as to be housed in an internal housing 10d of the body 10 of complementary shape. This configuration allows rotation of the internal body 20a relative to the body 10 of the distribution device 1 about at least two perpendicular axes X, Y. In the example of FIGS. 1 and 2, the axis X corresponds to a longitudinal axis of the distribution device, the axis Y corresponding to a transverse axis of the device.
(29) The selection device 20 comprises a control element 20b, in the example a movable button 20b, secured to the internal body 20a. The button 20b extends outside the body 10 of the distribution device 1, the button 20b being connected to the internal body 20a by a rod 20c passing through an opening 10e formed in the body 10 and communicating with the housing 10d. The rod 20c extends from the internal body 20a along an axis Z perpendicular to the two axes X, Y of rotation of the internal body 20a. In the example, the button 20b has a general shape that is symmetrical about the axis Z.
(30) The internal body 20a is movable between a plurality of positions, and in particular between a plurality of distribution positions. A distribution position is a position of the internal body 20a (and therefore of the selection device 20) in which the latter puts the supply channel 10b and at least one of the distribution channels 14b, 16b, 18b in fluid communication, so that a flow of water entering the distribution device 1 via the supply channel 10b is directed, via the internal body 20a of the selection device 20, towards at least one of the distribution channels, and therefore towards the corresponding nozzle group(s) Of course, the cooperation between the internal body 20a and its housing 10d ensures sufficient sealing, in order to prevent any leak and to ensure that the entire flow entering the supply channel 10b is distributed to the selected distribution channel(s). For this purpose, it may be possible to provide for sealing elements to be interposed between the housing 10d and the internal body 20a.
(31) Advantageously, it can be provided that the internal body 20a, and therefore the selection device 20, is also capable of assuming at least one stop position, position in which a flow entering the supply channel 10b will be blocked and will therefore not be directed to any of the distribution channels. When the selection device 20 is in a stop position, the blocking of a flow entering the supply channel 10b can be carried out at the interface between the supply channel 10b and the selection device 20 and/or at the interface between the selection device 20 and the different distribution channels 14b, 16b, 18b.
(32) In the example of FIG. 2a, the internal body 20a of the selection device comprises an internal through channel 20d. The internal channel 20d comprises: at a first end, an inlet configured to be in fluid communication with the supply channel 10b when the internal body 20a is in a distribution position, and at a second end, an outlet configured to be in fluid communication with at least one of the distribution channels 14b, 16b, 18b when the internal body 20a is in a distribution position.
(33) In the example, the internal channel 20d has a straight cylindrical shape and therefore has a constant cross section, but it can be of any other suitable shape. In particular, the internal channel 20d may have a non-cylindrical shape, for example a conical shape. The internal channel 20d may also have a non-straight shape, for example a bent shape.
(34) FIG. 2b illustrates a selection device, in which the internal channel 20d comprises a bent portion 21. The bent portion 21 can form a bend whose angle is between 60 and 150. In the example of FIG. 2c, the bent portion 21 forms a bend whose angle is equal to 90. Providing that the internal channel 20d has a bend allows any movement of the control element 20b to result in a movement of the outlet orifice of the internal channel 20d (in particular when the control element 20b causes a rotational movement of the internal body 20a about the axis X). When the bent portion is configured so that the outlet orifice of the internal channel 20d is diametrically opposite to the control element 20b (for example in the case where the outlet orifice is centered on the Z axis of the FIG. 2a), then any movement of the control element 20b implies a movement of the same angular amplitude of the outlet orifice of the internal channel 20d.
(35) As shown in FIG. 2c, the internal channel 20d may have at least one bifurcation 22, at which it divides into at least two branches 22a, 22b. Thus, the internal channel 20d can comprise a single inlet and two or more outlets. The presence of at least two outlets can, for example, make it possible to simultaneously put the internal channel 20d in fluid communication with at least two distribution channels. Such a configuration can also make it possible to put the internal channel 20d in fluid communication with a single distribution channel, via only one of the outlets, the other outlet(s) then being obstructed due to the position of the internal body 20a. The presence of at least one bifurcation 22 can facilitate the management of sealing between the internal channel 20d and the different distribution channels 14b, 16b, 18b, in particular when at least one distribution position is provided, making it possible to simultaneously supply at least two distribution channels 14b, 16b, 18b. Indeed, in such a case, the presence of at least one bifurcation makes it possible to provide one outlet per distribution channel that must be connected simultaneously. As visible in FIG. 2c, each outlet of the internal channel 20d can be put in fluid communication with a respective distribution channel 14b, 16b, 18b. Such a configuration simplifies the management of sealing as well as the integration of distribution channels (particularly from the point of view of space requirements). Furthermore, providing at least one bifurcation 22 can make it possible to increase the capacities of the selection device 20, in particular by increasing the number of possible distribution positions. Indeed, as visible in FIG. 2a, a rotation of the internal body 20a about the axis X implies a rotation of the internal channel 20d about its longitudinal axis when the latter coincides with the axis X. In the case of FIG. 2a, such a rotation does not imply any change from the point of view of the connection between the internal channel 20d and the distribution channels 14b, 16b, 18b. On the other hand, as visible in FIG. 2c, the presence of the bifurcation 22 implies that the outlets of the two branches 22a, 22b are offset with respect to the longitudinal axis of the internal channel 20d, and therefore with respect to the axis X. Thus, a rotation of the internal body 20a about the axis X implies a change in position of the outlets of the branches 22a, 22b. Such a rotation is therefore likely to modify the state of fluid communication between the internal channel 20d and the distribution channels 14b, 16b, 18b, and can therefore correspond to a change in distribution position.
(36) As visible in particular in FIG. 2a, the selection device 20 allows a user to select, by simply moving the button 20b, which group(s) of nozzles 14, 16, 18 will be supplied with water. The design of the selection device 20 allows in particular a direct selection of a distribution position (and therefore of a type of jet), without necessarily passing through other positions beforehand, or at least not according to a predetermined and obligatory sequence. FIGS. 3a to 3d show the selection device 20 seen from above, in different positions of the button 20b and therefore of the internal body 20a. FIG. 3a represents the selection device 20 in a neutral position, which can correspond to a distribution position or to a stop position, depending on the configuration of the device. FIGS. 3b, 3c, 3d show the selection device in different positions of the button 20b. Each of these positions can correspond to a distribution position or to a stop position of the internal body 20a, depending on the configuration of the device.
(37) FIGS. 4a and 4b illustrate a configuration of the distribution device 1, in which the distribution channels 14b, 16b, 18b are adjacent and are united within a distribution assembly 10f, which in the example has a circular cross section. Thus, as visible in FIG. 4b, the distribution assembly 10f is formed by a channel of circular section comprising internal separation walls 100, these internal walls being oriented radially in the example. Each internal wall 100 constitutes a separation between two adjacent internal spaces, each internal space forming one of the distribution channels 14b, 16b, 18b.
(38) 4b shows in dotted lines different positions of the outlet of the internal channel 20d of the internal body 20a of the selection device 20. In a first position P1, the outlet of the internal channel 20d is aligned with the center of the distribution assembly 10f. In this position, the three distribution channels 14b, 16b, 18b are in fluid communication with the internal channel 20d, and each of these three distribution channels is supplied by a flow of water. In this position, the three groups of nozzles 14, 16, 18 are therefore supplied simultaneously. In a second position P2, the outlet of the internal channel 20d is opposite a single distribution channel 14b, and only the corresponding group of nozzles 14 will be supplied. In a third position P3, the outlet of the internal channel 20d is opposite two of the distribution channels 14b, 18b, and the corresponding internal wall 100 is aligned with a median plane of the internal channel 20d. In this position, the two distribution channels 14b, 18b are supplied simultaneously, with a substantially equal flow rate (the effective distribution of the flow rates being, however, also dependent on the configuration of the different distribution channels and the associated groups of nozzles). In a third position P4, the outlet of the internal channel 20d is opposite two of the distribution channels 16b, 18b, and the corresponding internal wall 100 is offset with respect to a median plane of the internal channel 20d. In this position, the two distribution channels 16b, 18b are supplied simultaneously, but with different respective flow rates.
(39) The configuration of the selection device 20 shown in FIGS. 4a and 4b therefore allows, at the user's choice, to use a single group of nozzles, to simultaneously use at least two groups of nozzles, and, in this case, to vary the respective flow rates of each of the groups of nozzles supplied.
(40) FIG. 5 shows a variant of the distribution device 1, in which the selection device 20 makes it possible to vary the flow rate entering a distribution channel. The distribution device of FIG. 5 comprises distribution channels 14b, 16b, 18b, 14c, 16c, 18c, 19b spaced apart from each other, in the example of circular cross section in the example.
(41) The shape and the dimensions of the outlet of the internal channel 20d of the internal body 20a, shown in dotted lines in several distribution positions P1, P5, make it possible to select at least one of the distribution channels, and also make it possible to vary the flow entering into the selected distribution channel. In the example of FIG. 5, the internal channel 20d of the internal body 20a has a triangular cross section.
(42) FIGS. 6a to 6c show a variant of the distribution device 1, in which the selection device makes it possible to vary, depending on the position of the selection device 20, the supply flow rate of a distribution channel, as well as to obtain a stop position. We show in FIGS. 6a to 6c a cross section of the distribution channels 14b, 16b, 18b, 19b, which are four in number in the example, and united within a distribution assembly 10f similar to that of the FIGS. 4a and 4b. The distribution channels 14b, 16b, 18b, 19b thus form sectors within this distribution assembly 10f and are further shaped so that a central location of the distribution assembly 10f, corresponding to a neutral position of the selection device 20, is not occupied by a distribution channel. Thus, as shown in FIG. 6a, in which the position of the internal channel 20d is shown in dotted lines, the neutral position of the selection device 20 (and therefore of the internal body 20a) corresponds to a stop position, position in which no flow entering the supply channel is transmitted by the selection device 20. The configuration of the selection device 20 of FIGS. 6a to 6c also makes it possible to vary the flow rate supplied to a distribution channel, as visible in FIGS. 6b and 6c, which show two distribution positions P6, P7 of the internal body 20a, position in which the internal channel 20d is in fluid communication with one of the distribution channels 14b, 16b, 18b, 19b. These different positions make it possible to obtain a more or less high flow rate, depending on the section of the internal channel 20d located opposite the corresponding distribution channel 16b.
(43) FIGS. 7a to 7d show a variant of the distribution device 1 in which a system for guiding the internal body 20a of the selection device 20 is provided. As visible in FIG. 7a, the guide system comprises a follower element 20e, in the example a lug secured to the internal body 20a, this follower element cooperating with a fixed guide device relative to the body 10 of the distribution device. In the example, the guide device comprises one or more grooves 20f, 20g, 20h making it possible to guide the follower element 20e, and thus to limit the movement of the internal body 20a to predefined paths. FIGS. 7b to 7d show examples of the guide device of the follower element 20e. FIGS. 7b to 7d are partial sectional views of the body 10 of the distribution device, showing the guide device seen from above. In FIG. 7b, the guide device comprises three main grooves 20f of radial orientation, distributed angularly, and communicating with each other at a central zone corresponding to the neutral position of the internal body 20a (and therefore of the selection device 20). In such a configuration, the selection device 20 can thus be maneuvered in three different directions, as shown by the arrows shown in FIG. 7b.
(44) FIG. 7c shows a guide device similar to that of FIG. 7b, but additionally comprising a circular peripheral groove 20g, communicating with each of the main grooves 20f. As shown by the arrows in FIG. 7c, such a configuration makes it possible to maneuver the selection device in a circular movement, in addition to the three main directions. FIG. 7d shows a guide device similar to that of FIG. 7c, but comprising in addition three secondary grooves 20h of radial orientation, angularly distributed in different directions from the main grooves 20f. In the example, the secondary grooves 20h do not communicate with the peripheral groove 20g, and have a length less than that of the main grooves 20f. It is therefore understood that the movement of the internal body 20a in a direction corresponding to one of the secondary grooves 20h will have a more limited amplitude than in a direction corresponding to one of the main grooves 20f. As can be seen from the examples in FIGS. 7b to 7d, a guide system of the selection device 20 makes it possible to impose directions of movement and/or limit the amplitude of movement in certain directions of movement. Alternatively, the guide system described above could be configured so that the follower element 20e is fixed relative to the body 10 of the distribution device, while the guide device is secured to the internal body 20a of the selection device, the guide device comprising, for example, one or more grooves formed on the surface of the internal body 20a.
(45) FIG. 8 shows a variant of the distribution device comprising a system for constraining the movement of the internal body 20a. Such a system comprises one or more elastic return devices, such as springs 20i, configured to bias the internal body 20a towards the neutral position of the selection device, and/or to limit the amplitude of movements of the internal body, and/or to introduce a force feedback which is perceptible by the user. In the example of FIG. 8, there is provided a set of springs 20i secured on the one hand to the internal body 20a via a lug 20e, the springs being on the other hand secured to the body 10 of the distribution device.
(46) FIGS. 9a and 9b show a variant of the selection device 20, in which the button 20b is movably mounted on the internal body 20a. In the example of FIGS. 9a and 9b, the rod 20c carrying the button 20b is mounted movable in translation in the internal body 20a, along the axis Z. The possibility of movement of the button 20b relative to the internal body 20a allows to provide additional functions of the selection device. In the example, the movement of the button 20b makes it possible to open and close the internal channel 20d of the internal body 20a. For this purpose, the rod 20c is movable between a first position (visible in FIG. 9a), in which the rod 20c closes the internal channel 20d, and a second position (visible in FIG. 9b), in which the rod leaves the internal channel 20d open. The rod 20c has a through opening 20j which coincides with the internal channel 20d when the rod 20c is in the second position. Preferably, the selection device 20 comprises a system for indexing the position of the rod (not shown), associated with a spring 20k, allowing a user to pass from the first to the second position, and vice versa, by pressing the button 20b.
(47) FIGS. 10a and 10b show a variant of the selection device 20, in which a flow of water entering the supply channel 10b of the distribution device 1 is not modified or redirected directly by the internal body 20a, but via one or more movable activation elements 201, the activation element(s) 201 being moved by the internal body 20a. In the example of FIGS. 10a and 10b, the activation element 201 comprises an internal channel 20m which is in fluid communication with the supply channel 10b and which can be connected, directly or indirectly, to one or the other of the distribution channels 14b, 16b, 18b. In the example of FIGS. 10a and 10b, the activation element 201 puts the supply channel 10b in fluid communication with one or more of the distribution channels 14b, 16b, 18b via a fixed interface element 20n, the latter comprising a plurality of internal channels 20o, each internal channel 20o being respectively connected to one of the distribution channels 14b, 16b, 18b. In the example of FIG. 10a, the interface element 20n comprises three juxtaposed channels 20o, the distribution channels 14b, 16b, 18b also being juxtaposed.
(48) In the example of FIG. 10b, which is a partial sectional view of the body 10 showing the interface element 20n seen from above, the interface element 20n is of circular shape, and each internal channel 20o opens onto an internal space forming a sector of this element. Thus, the movement of the activation element 201 makes it possible to simultaneously put the supply channel 10b in fluid communication with one or more internal channels 20o of the interface element 20n, and therefore a distribution channel in a selective manner, or with several distribution channels. By preventing a flow of water entering the supply channel 10b from being redirected directly by the internal body 20a of the selection device 20, and redirecting it instead via one or more activation elements 201 external to the internal body 20a, the selection device 20 of FIGS. 10a-10b can make it possible to simplify the management of the sealing thereof.
(49) FIG. 11a represents a distribution device 1 of the showerhead type. In this configuration, the distribution device 1 can be fixed to a wall, and connected to a water supply pipe via a rigid tubular arm 2. In the example of FIG. 11a, the distribution device selection 20 is arranged near the distribution head 12, behind the distribution face 12a.
(50) FIG. 11b represents a distribution device 1 of the showerhead type, in which the selection device 20 is arranged at the distribution face 12a of the distribution head. For this purpose, the body 10 of the distribution device is configured such that the housing 10d containing the internal body 20a of the selection device 20 opens at the distribution face 12a. In the example, the opening 10e of the housing 10d is located in the center of the distribution face 12a.
(51) In the example of the figures, the internal body 20a is movable in rotation about two perpendicular axes X, Y of rotation, that is to say the mechanical connection between the internal body 20a and the body 10 of the distribution device is a spherical finger type connection (or ball joint with finger). It can be provided that the internal body 20a is movable in rotation about three axes X, Y, Z of rotation perpendicular two by two, the mechanical connection between the internal body and the body of the distribution device then being of the ball joint type. In this case, the third axis Z of rotation is parallel to the axis of extension of the rod carrying the control element, and therefore parallel, in the example, to the axis of symmetry of the control element 20b. In such a configuration, it can be provided that the rotation of the control element 20b on itself allows a user to control a function. For example, it could be provided that when the selection device is in a distribution position, rotation of the control element causes the flow rate to vary.
(52) Advantageously, whatever the configuration of the selection device 20, a flow limiting device can be provided on all or some of the distribution channels, making it possible to limit the flow in the corresponding channels, whatever the pressure of the entering flow of water. Furthermore, a regulation device could be provided at the supply channel, making it possible to limit the pressure experienced by the selection device.
(53) Advantageously, the selection device can comprise one or more stops, making it possible to limit the amplitude of the movement of the internal body 20a.
(54) Advantageously, the internal body 20a of the selection device can comprise at least two internal channels. When the distribution device comprises a single supply channel, then, in at least one position of the selection device, the two internal channels can be put simultaneously in fluid communication with the supply channel. When the distribution device comprises at least two separate supply channels, it can be provided that, in at least one position of the selection device, the internal channels are each put in fluid communication with a respective supply channel. In such a configuration, it could be envisaged that the supply channels serve to supply different fluids, for example water and air.
(55) The distribution device advantageously comprises a diffusing device for a product, in particular an encapsulated product, the diffusing device being configured to diffuse a product contained in an extractable capsule or in any other suitable container (for example a reservoir secured to the distribution device and fillable by the user) into the flow(s) of water ejected by the distribution device, the diffusing device being arranged, for example, in the distribution head.
