Description

MIXER AND METHOD FOR INTERVERTING SUCH A MIXER

The present invention relates to a mixer tap and a method for interverfing such a mixer tap.

The invention relates to the valve industry, in particular for sanitary use.

EP 2,386,927 A2 describes a thermostatic mixer tap comprising a body, provided with a hot water feed and a cold water feed and several mixed water outlets.

This mixer tap also comprises a thermostatic core arranged within the body near the hot water feed of the mixer tap. This thermostatic core accommodates a thermostatic cartridge, which determines the outlet temperature of the mixed water. The thermostatic core comprises a hot water feed, directly connected to the hot water feed of the tap, as well as a cold water feed and a mixed water outlet. The cold water feed of the thermostatic core is connected to the cold water feed of the mixer tap by means of a pipe passing longitudinally through the body of the mixer tap to connect the cold water feed of the mixer tap to the cold water feed of the cartridge. This mixer tap also comprises a bypass core arranged within the body, near the cold water feed of the mixer tap, and accommodating a bypass cartridge, which determines the outlet flow rate of the mixed water through one of the outlets. The bypass core is connected to the mixed water outlet of the thermostatic core by means of a pipe passing longitudinally through the body of the mixer tap, to couple the two cores together.

The arrangements of this known mixer tap, although satisfactory on many aspects, nevertheless have some drawbacks. In particular, during the installation of the mixer tap to serve a shower or a bathtub, the two feeds of the mixer tap are respectively connected to two water supply pipes, which generally protrude from a wall adjacent to the basin of the bathtub or shower, or any similar support. These two supply pipes may have a reversed configuration in that, if the mixer tap is connected to these pipes without modifying the installation, the cold water feed of the mixer tap is supplied with hot water and the hot water feed is supplied with cold water by the supply pipes. The mixer tap then cannot function correctly, in particular if it includes a thermostatic control function. It is therefore necessary, when possible, to modify the installation in order to intervert the wall supply pipes in order to supply the mixer tap correctly, which causes considerable lost time.

The invention aims to address the aforementioned drawbacks by proposing a new versatile mixer tap, which is particularly easy to install and.

The invention relates to a mixer tap according to claim 1.

Owing to the invention, the internal assembly is configured to transition between a direct configuration and an indirect configuration, in which the primary and secondary modules are interverted relative to the direct configuration. In the indirect configuration, the respective connections between the two feeds of the mixer tap and the primary and secondary inlets of the modules are swapped relative to the direct configuration. For example, in the case where the direct configuration corresponds to a situation where the mixer tap is designed to receive cold water at the first feed and hot water at the second feed, whereas in the case at hand, the installation supplies hot water at the first feed and cold water at the second feed, it is possible to modify the mixer tap easily, in particular in the installation site of the mixer tap, by transitioning it to the indirect configuration, such that the mixer tap becomes able to receive hot water at the first feed and cold water at the second feed. Owing to these two configurations, it is not necessary to modify the installation, a transition from one configuration of the mixer tap to the other being possible to address the problem. This allows substantial time savings in the installation of the mixer tap. The installation process is made easier as a result.

The intake volume arranged between the collars of the pair of collars makes it possible, in case of interversion, to ensure that the connection of the primary or secondary inlet in question of the internal assembly is tight, whether with the first feed or the second feed, even if the first feed and the second feed are formed using a different geometry from one to the other. Furthermore, this makes it possible for the internal assembly to be suitable for being mounted within several different tubular bodies, in particular when the geometry or the position of the feeds differs.

Several advantageous and optional features of the invention are defined hereinafter: - two pairs of collars are provided, including: a pair of primary collars, which are attached to the primary module and which delimit a primary feed volume between them in which the primary inlet emerges and in which, in the direct configuration, the first feed emerges, and in the indirect configuration, the second feed emerges; and a pair of secondary collars, which are attached to the secondary module and which delimit a secondary intake volume between them in which the secondary inlet emerges and in which, in the direct configuration, the second feed emerges, and in the indirect configuration, the first feed emerges.

-the pair of primary collars is identical to the pair of secondary collars.

- the pair of primary collars is symmetrical with respect to the pair of secondary collars, relative to a plane orthogonal to the body axis.

- the tubular body comprises a first anchoring member of the internal assembly and a second anchoring member of the internal assembly, which are distributed along the body axis; the primary module comprises a primary fastener, which, in order to fasten the primary module in translation parallel to the body axis, relative to the tubular body, can be fixed alternatively: to the first anchoring member, when the internal assembly is in the direct configuration, and to the second anchoring member, when the internal assembly is in the indirect configuration; the secondary module comprises a secondary fastener, which, in order to fasten the secondary module in translation, parallel to the body axis, relative to the tubular body, can be fixed alternatively: to the second anchoring member, when the internal assembly is in the direct configuration, and to the first anchoring member, when the internal assembly is in the indirect configuration.

the internal assembly is configured so that the primary module and the secondary module can be separated from one another, the tubular body comprising: a first opening at the first end, such that the primary module and the secondary module can alternatively be introduced into the tubular body by translation along the axis of the body through the first opening; and a second opening at the second end, such that the primary module and the secondary module can alternatively be introduced into the tubular body by translation along the axis of the body through the second opening.

-the internal assembly comprises a coupler: which connects the primary outlet with the subsidiary inlet; which connects the secondary inlet with the auxiliary inlet; and which authorizes a sliding of the primary module relative to the secondary module parallel to a sliding axis of the internal assembly.

- the coupler authorizes the sliding of the primary module relative to the secondary module while the primary outlet remains connected with the subsidiary inlet and while the secondary inlet remains connected with the auxiliary inlet, such that the sliding makes it possible to adapt the internal assembly to the geometry of the tubular body.

- the coupler comprises: a first primary tube, which is fastened relative to the mixer parallel to the sliding axis, which is connected to the auxiliary inlet and which emerges along a first direction parallel to the sliding axis; a first secondary tube, which is fastened relative to the adjuster parallel to the sliding axis, which is connected to the secondary inlet, which emerges along a second direction opposite the first direction and which is fitted in a sliding manner with the first primary tube parallel to the sliding axis, so as to connect the auxiliary inlet with the secondary inlet; a second primary tube, which is fastened relative to the mixer parallel to the sliding axis, which is connected to the primary outlet and which emerges along the second direction; and a second secondary tube, which is fastened relative to the adjuster parallel to the sliding axis, which is connected to the subsidiary inlet, which emerges along the second direction and which is fitted in a sliding manner with the second primary tube parallel to the sliding axis, so as to connect the primary outlet with the subsidiary inlet.

- the second primary tube is coaxial with the first primary tube and is at least partially contained in the first primary tube; and the second secondary tube is coaxial with the first secondary tube and is at least partially contained in the first secondary tube.

- the secondary module comprises at least one rectilinear pipe, said at least one rectilinear pipe extending from the secondary inlet to the first secondary tube in a rectilinear manner, parallel to the sliding axis, the rectilinear pipe connecting the secondary inlet with the first secondary tube; and the first secondary tube, the second secondary tube and said at least one rectilinear pipe forming, in a single piece, a secondary part of the secondary module, the secondary inlet being formed in the secondary part and the adjuster being fastened to the secondary part.

The invention also relates to a method for interverting a mixer tap, the mixer tap being according to the preceding, the method including the following successive steps: while the mixer tap is in the direct configuration, disassembling the internal assembly from the tubular body; and mounting the internal assembly, such that the internal assembly is contained in the tubular body in the indirect configuration.

The invention will be better understood using the following preferred examples, provided as an illustration and for non-limitative purpose, and described in reference to the appended drawings, in which: figure 1 is a perspective view of a mixer tap according to a first embodiment, comprising an internal assembly, in accordance with the invention; figure 2 is a view similar to figure 1, where the mixer tap of figure 1 is shown in exploded view; figure 3 is a sectional view of figure 1 along plane XY; figure 4 is a sectional view of figure 1 along plane XZ; figure 5 is a view similar to figure 3, showing a mixer tap according to a second embodiment, including the internal assembly of the preceding figures; figure 6 is a view similar to figure 3, showing a mixer tap according to a third embodiment, including the internal assembly of the preceding figures.

Figures 1 and 2 show a thermostatic mixer tap 1, which is a specific type of tap. The mixer tap 1 is intended for sanitary use. The mixer tap 1 is of the wall type, to be installed for a shower or bathtub.

Without going beyond the scope of the invention, it is possible to provide that the mixer tap is not intended for a wall, but is for example intended to be installed on a washbasin or sink. It would also be possible to provide that the mixer tap is intended for a use other than sanitary, for example an industrial use.

The mixer tap 1 comprises a tubular body 2, that is to say, has the form of a hollow cylinder, in the present example, with a circular base. It is possible to provide a tubular body with a square base, or any other form depending on the application. The tubular body 2 defines, for example coaxially with its cylindrical shape, an axis X2, called "body axis". The tubular body 2 comprises two axial ends 3 and 4 passed through by this axis X2.

In the present text, the terms such as "axial", "coaxial" and "radial" refer to the axis X2 or to any axis coaxial to the axis X2, unless otherwise mentioned.

The mixer tap 1 comprises water feeds 5 and 6, or more generally, feeds for any liquid that one wishes for the mixer tap 1 to provide, as well as two outlets 7 and 8, in order to deliver any water introduced by the feeds 5 and 6 outside the mixer tap 1. In a variant, it is possible to provide a single outlet or a number of outlets greater than two for the mixer tap.

In the present document, each inlet, feed and outlet can comprise a single orifice or a group of several orifices, preferably positioned near one another.

The feed 6 is preferably connected to a "hot" water source and the feed 5 is preferably connected to a "cold" water source, or at least with a temperature lower than that of the hot water.

The feed 5 and the feed 6 each comprise an orifice that passes through the tubular body radially, the orifice of the feed 5 being coaxial with an axis Y5 orthogonal to the axis X2 and the orifice of the feed 6 being coaxial with axis Y6 orthogonal to the axis X2. The axes Y5 and Y6 are parallel. The feeds 5 and 6 are located on a same side of the body 2, around the axis X2. The outlets 7 and 8 each comprise an orifice that passes through the tubular body radially, these orifices being, in the present example, coaxial with a same axis Z7, orthogonal with the axis X2. The outlets 7 and 8 are symmetrically opposite one another relative to the axis X2.

The plane XY is defined by the axes X2 and Y5 and/or Y6. The plane XZ is defined by the axes X2 and Z7.

The feed 5 is located axially on the side of the end 3, while the feed 6 is located axially on the side of the end 4. In other words, the feed 5 is axially located between the end 3 and the feed 6, while the feed 6 is between the feed 5 and the end 4. The outlets 7 and 8 are axially located between the feeds 5 and 6.

The tubular body 2 comprises an inner wall 9, presently with a generally cylindrical shape with a circular base. From this inner wall 9, the feeds Sand 6 emerge as shown in figure 3, as well as the outlets 7 and 8 as shown in figure 4.

At its ends 3 and 4, the body 2 respectively comprises an opening 10 and an opening The mixer tap 1 comprises an internal assembly, which is contained inside the body 2, so as to be surrounded over most or all of its axial length by the inner wall 9. In the present example, the internal assembly is partially contained in the body 2, inasmuch as a minimal part of the internal assembly protrudes axially from the ends 3 and 4 via the openings 10 and 11. The internal assembly defines a main axis X13, called "sliding axis", which is coaxial with the axis X2 when the internal assembly is mounted within the body 2. The internal assembly comprises a primary module 13 and a secondary module 15 that are distributed along the axis X13. Preferably, the axis X13 passes through both modules 13 and 15. Each of these modules 13 and 15 constitutes a subassembly of parts that are secured to one another, these two subassemblies being able to be separated from one another.

A direction R13 is defined, coaxial to the axis X13 and oriented from the module 15 toward the module 13. An opposite direction R15 is defined.

The primary module 13 comprises a mixer 17. The mixer 17 preferably has a general shape of revolution coaxial to the axis X13. At the very least, the mixer 17 is centered on the axis X13. Preferably, when the module 13 is mounted, the mixer 17 is axially located across from the feed 5, near the end 3.

The mixer 17 comprises an adjustable control 19, called "primary control", which, in the illustrated example, assumes the form of a shaft coaxial with the axis X13, rotating relative to the body 2 around the axis X13 and protruding axially along the direction R13 through the opening 10. When the mixer tap 1 is assembled, a user can actuate the control 19 without disassembling the mixer tap 1.

The mixer 17 comprises a radial inlet 21, a radial inlet 23 and a coaxial outlet 25. The inlet 23 is advantageously located axially between the inlet 21 and the outlet 25. The inlet 21 is advantageously located in the direction R13 relative to the outlet 25. The outlet and the control 19 are preferably axially at the ends of the mixer 17, the control 19 being in the direction R13 and the outlet 25 in the direction R15. When the module 13 is mounted, the inlet 21 is located axially at the height of the feed 5, or at the least, near the feed 5.

The mixer 17 is configured to supply water to the outlet 25 by mixing two streams of water respectively supplied to the inlets 21 and 23, the mixing being done in particular as a function of the adjustment of the control 19. Preferably, the inlet 21 is provided to receive cold water, the inlet 23 to receive hot water, while the outlet 25 is provided to emit mixed water, that is to say, a temperature midway between those of the cold water and the hot water supplied to the inlets 21 and 23. The adjustment of the control makes it possible to act on the desired temperature for the water emitted by the outlet 25, which leads the mixer 17 to modify the water flow rate respectively admitted to the inlets 21 and 23. Preferably, this mixer 17 is a thermostatic cartridge, such that the incoming water flow rates at the inlets 21 and 23 are regulated as a function of the outlet temperature and the adjustment of the control 19, using a system internal to the cartridge, for example including one or several thermo-actuators. The mixer tap 1 is then a thermostatic mixer tap.

It would alternatively be possible, without going beyond the scope of the invention, to provide that the mixer 17 is a simple mixing device, with no specific thermostatic control. The mixer tap 1 is then a simple mixer tap.

In the present example, the inlet 21 forms a so-called "primary inlet" of the module 13. In a variant, it is possible to provide that the inlet 21 is connected to a primary inlet separate from the module 13.

Unless otherwise mentioned, in the present document, expressions such as "object A is connected to object B" indicate that object A, and only object A, is fluidly connected to object B, and only to object B, such that the liquid supplied to object A is necessarily conducted to object B and vice versa.

The inlet 23 of the present example constitutes an "auxiliary inlet" of the module 13.

The outlet 25 of the present example constitutes a "primary outlet" of the module 13. The module 13 also comprises a primary part 30, which is preferably essentially or completely formed in one piece. The primary part 30 has a relatively simple shape, such that it can advantageously be made from a plastic material, so that it is particularly easy to manufacture, compared to the metal parts of the internal assemblies of the prior art. It would, however, be possible to make the primary part 30 from a metal material.

The primary part 30 has a generally tubular shape coaxial with the axis X13.

The primary part 30 comprises a fastening base 32, which forms a part of the generally tubular shape and extends in the direction R13 up to an axial end of the primary part 30. The primary part 30 is axially fastened to the mixer 17 by means of the base 32. To that end, the base 32 surrounds the cylindrical body of the mixer 17, at the axial height of the inlet 21. The base 32 is provided with one or several orifices 34 passing radially through the base 32, such that the water can flow radially from the outside of the base 32, through the orifices 34, into the inlet 21.

The mixer 17 advantageously bears one or several sealing fittings 36 interposed radially between the base 32 and a cylindrical outer wall of the mixer 17, the fittings 36 being distributed around the inlet 21 so as to ensure the sealing between the base 32 and the mixer 17 around the inlet 21, in particular in order to separate the inlet 21 from the inlet 23 and the opening 10 of the body 2. In the present example, there are two fittings 36, each of which comprise an 0-ring that is positioned in a plane orthogonal to the axis X13 and which are distributed axially on either side of the inlet 21. Thus, the water passing through the orifices 34 toward the inlet 21 cannot reach the inlet 23 or escape outside the body 2 through the opening 10.

In the present document, expressions such as "tight" refer to tightness against the liquid dispensed by the mixer tap 1.

The primary part 30 comprises a connector for connecting the inlet 21 to the feed 5.

In the present example, this connector comprises a pair of primary collars 38, which are radial and external, formed at the radial periphery of the base 32. Each collar 38 is in fight contact, radially outwardly, with the inner wall 9 of the body 2 over an entire perimeter of the inner wall 9 around the axis X2. In the present example, each collar 38 is in tight contact along a circle with the inner wall 9, this circle being coaxial to the axis X2. Advantageously provided, for each collar 38, is a tight fitting providing the radial seal between the wall 9 and the collar 38. The collars 38 are axially spaced apart from one another, while being positioned axially on either side of the orifices 34, the inlet 21 and the feed 5. The base 32, the inner wall 9 and the collars 38 thus delimit a water intake volume 39, called "primary volume", in ring form, in which both the feed 5 and the inlet 21 emerge, via orifices 34. Thus, the water coming from the feed 5 can only reach the inlet 21, one of the collars 38 preventing the water from progressing in the direction R15 and spreading in the body 2, the other of the collars 38 preventing the water from progressing in the direction R13 and escaping outside the body 2 through the opening 10. Advantageously, the interior volume of the body 2 is axially tightly closed off by a subassembly including the part 30 and the mixer 17, at each collar 38.

In the configuration of the figures, the inlet 21 is thus connected to the feed 5.

The primary volume 39 arranged between the collars 38 makes it possible for the internal assembly to be suitable for being mounted within several different tubular bodies, in particular when the geometry of these tubular bodies differs. The primary volume 39 is suitable for connecting the inlet 21 to a liquid feed of the tubular body, in different axial positions along the body axis, and in any angular position around the body axis. For example, in the second embodiment illustrated in figure 5, the same internal assembly as that illustrated in figures 1 to 4 is mounted within a tubular body 102 that is geometrically different from the tubular body 2 of figures 1 to 4, in that the axial position of a water feed of the body 102 differs relative to that of the feed 5 of the tubular body 2, along a body axis X102 of the body 102. In particular, relative to the feed 5, the feed 105 is offset in the direction R15. Despite this shift, as long as the feed 105 emerges in the primary volume 39, the collars 38 ensure the connection between the feed 105 and the inlet 21. The internal assembly is thus particularly versatile and is suitable, without modification of its structure, for several tubular mixer tap bodies, with different geometries.

Preferably, the primary part 30 also comprises a tube 40, called primary tube, that is securely attached, in one piece, with the base 32, in the direction R15 relative to the base 32. In the example, the tube 40 axially extends, in the direction R15, the collar 38 located in the direction R15. Preferably, the tube 40 is axially fastened relative to the mixer 17. The tube 40 is in the shape of a hollow cylinder with a circular base. The tube 40 emerges at its axial end in the direction R15. The tube 40 radially surrounds the inlet 23 and optionally the outlet 25 of the mixer 17. The tube 40 also emerges at its other end in the direction R13, while being tightly closed off in this location by the body of the mixer 17 and one of the sealing gaskets 36. The tube 40 thus being closed off by the mixer 17, it delimits, with the mixer 17, an interior space in the form of a bell open along the direction R15 and closed along the direction R13.

Advantageously, the tube 40 is a portion of the part 30 that is particularly simple to manufacture, inasmuch as it extends essentially or completely rectilinearly from the inlet 23, or at least from the base 32, to its outlet in the direction R15.

The primary module 13 also comprises a tube 42, which, in the example, constitutes a part separate from the part 30, and securely attached to the mixer 17. It would advantageously be possible to provide that the tube 42 is formed in one piece with the part 30.

The tube 42 is advantageously cylindrical with a circular base. In the present example, the tube 42 is coaxial with the axis X13 and radially surrounds the outlet 25 of the mixer 17. The tube 42 is radially inserted between the outlet 25 and the inlet 23, that is to say, in particular, that the tube 42 does not surround the inlet 23. The tube 42 is fastened, at least axially, to the mixer 17, while being positioned so as to extend, in the direction R15, the axial end of the mixer 17 located in the direction R15. The tube 42 emerges in the direction R15. The tube 42 is closed off by the body of the mixer 17 in the direction R13, in a location where the outlet 25 emerges in the tube 42. Advantageously, the tube 42 is a part that is particularly simple to manufacture, inasmuch as it extends rectilinearly from the outlet 25 to where it emerges in the direction R15.

In the present example, the tubes 40 and 42 are coaxial, the tube 42 being radially contained in the tube 40, which not only makes it possible to save considerable space relative to two parallel and non-coaxial tubes, but also allows guiding of the water streams with the lowest possible head losses, in light of the arrangement of the various feeds, inlets and outlets of the mixer tap 1.

In a variant, it is possible to provide that the primary tubes are parallel and not coaxial.

Whatever the variant, the end along the direction R15 of each tube 40 and 42 is respectively connected to the inlet 23 and the outlet 25 of the mixer, without meeting of the water streams circulating in the tube 40 outside the tube 42 and the water stream circulating in the tube 42.

The module 13 comprises a nut 44 for performing axial fastening of the module 13 relative to the body 2. This nut 44 therefore has a primary fastening function of the module 13 relative to the body 2. The nut 44 is coaxial with the axis X13 and is located at an axial end of the module 13 in the direction R13. Reciprocally, the body 2 comprises an inner thread 46, provided at the opening 10, in which the nut 44 can be screwed. The nut 44 is advantageously attached against an axial surface of the base 32, facing in the direction R13. Another axial surface of the base 32, facing in the direction R15, in turn bears against an axial shoulder 48 formed on the inner wall 9 of the body 2, such that the axial fastening of the module 13 is obtained by axial interposition of the part 30 between the shoulder 48 and the nut 44. The thread 46 and the shoulder 48 have an anchoring member function of the module 13 relative to the body 2.

In place of the nut 44, the thread 46 and the shoulder 48, any other anchoring members and fasteners can be provided without going beyond the scope of the invention, for example a resilient washer system cooperating with a radial groove arranged hollowed out in the inner wall 9.

The secondary module 15 comprises a secondary part 50, which is preferably essentially or completely formed in a single piece. The part 50 has a relatively simple shape, such that it can advantageously be made from a plastic material, so that it is particularly easy to manufacture, compared to the metal parts of the internal assemblies of the prior art.

The secondary part 50 comprises a core 52, which forms a portion of the part 50 located at the end of the part 50 in the direction R15. The core 52 has a tubular shape coaxial with the axis X13, preferably with a section decreasing along the direction R13. As shown in figure 3, at its end along the direction R13, the core 52 comprises an opening forming an axial inlet 54, emerging in the direction R13, called "subsidiary inlet" of the module 15. This inlet 54 is advantageously coaxial with the axis X13. The part 50 comprises a tube 70, called "secondary tube", which is fastened in a single piece relative to the core 52, and which is therefore fastened axially relative to an adjuster 56 of the module 15 defined below. In the example, the tube 70 axially extends, in the direction R13, the core 52 located in the direction R15. The tube 70 is in the shape of a hollow cylinder with a circular base. The tube 70 emerges at its axial end in the direction R13 while being connected to the inlet 54 at its opposite end.

The tube 70 is fitted in a sliding manner with the tube 42 parallel to the axis X13. In the present example, it is provided that the tube 70 is female, while the tube 42 is male. It is, however, possible to provide the reverse without going beyond the scope of the invention. This fitting of the two tubes 42 and 70 is preferably tight, advantageously using a sealing gasket, for example borne by the tube 42. As a result, the outlet 25 of the module 13 is connected to the inlet 54 of the module 15 by a telescoping tube, formed by the tubes 42 and 70.

The core 52 comprises, at its end opposite the tube 40, that is to say, in the direction R15, a second axial opening. The adjuster 56 of the module 13 tightly closes off this second opening of the core 52, while being partially contained in the core 52 in the direction R15 relative to the inlet 54. More specifically, a body 58 of the adjuster 56 is fastened to the secondary part 50 by coaxial screwing in the core 52, whereas a moving member 60 of the adjuster 56, ensuring the adjustment, extends essentially inside the core 52. The body 58 has a general shape of revolution coaxial to the axis X13. The member 60 is located in the direction R13 relative to the body 58 and pivots with respect to the latter coaxially. To ensure the tightness of the closing off of the core 52 by the adjuster 56, a sealing gasket is advantageously provided between the body 58 and the inner wall of the core 52.

The adjuster 56 comprises a control 62, called secondary control, located at an axial end of the adjuster 56 opposite the member 60. In the illustrated example, the control 62 assumes the form of a shaft coaxial to the axis X13, rotating relative to the body 58 and therefore relative to the body 2 around the axis X13. The shaft of the control 62 protrudes in the direction R15 through the opening 11. When the mixer tap 1 is assembled, the user can actuate the control 62 without disassembling the mixer tap 1.

The secondary module 15 also comprises a secondary liquid outlet 64, served by the adjuster 56. The adjuster 56 is configured to supply, to the secondary outlet, the water coming from the inlet 54, while imposing a flow rate on this water stream passing through the adjuster 56. The imposed flow rate in particular depends on the adjustment of the control 62. In practice, it is possible to provide that the control 62 is secured in rotation with the member 60 in order to allow the adjustment of the flow rate, from a nil flow rate to a maximum flow rate.

Figure 4, which is pivoted by 90° around the axis X13 relative to figure 3, illustrates how this secondary outlet is made for the present example, which is preferred for reasons related to limiting head losses in the mixer tap 1. In the example, the core 52 comprises two radial openings that perform this function. Preferably, these two radial openings are diametrically opposite and located axially at the height of the member 60, so as to be served with water by the latter. Preferably, these two radial openings are axially located between the inlet 54 and the body 58 of the adjuster 56. The secondary outlet 64 can comprise a number of openings greater than or less than two.

The secondary part 50 comprises, respectively for each radial opening of the outlet 64, an axially rectilinear pipe 66. Each pipe 66 extends parallel to, and radially at a distance from, the axis X13, while being positioned along and radially outside the core 52. Each pipe 66 radially caps one of the radial openings of the outlet 64. Each pipe 66 is tightly closed off in the direction R15 [and] emerges in the direction R13 within a portion of the inner volume of the body 2, delimited by the inner wall 9 and by the module 13. The water reaching this inner volume is led to escape through the outlets 7 and 8.

Preferably, the secondary part 50 also comprises a tube 80, called "secondary tube".

This tube 80 is securely attached, in one piece, with the core 52, and therefore axially fastened relative to the adjuster 56. The tube 80 is located at the end of the part 50 in the direction R13. The tube 80 is in the form of a hollow cylinder with a circular base, that is to say, it has a rectilinear shape along the axis X13. The tube 80 is advantageously coaxial with the axis X13. Preferably, in order to optimize the available space within the mixer tap 1 while limiting the head losses for the water streams, the tube 80 coaxially surrounds the tube 70, such that a portion of the axial length of the tube 70 is contained in the tube 80. The tube 80 emerges at its axial end in the direction R13. The tube 80 is fitted in a sliding manner with the tube 40 parallel to the axis X13. In the present example, it is provided that the tube 40 is female, while the tube 80 is male. It is, however, possible to provide the reverse without going beyond the scope of the invention. This fitting of the two tubes 40 and 80 is preferably fight, advantageously using a sealing gasket, for example borne by the tube 80.

In the present example, the tubes 70 and 80 are coaxial, the tube 70 being radially contained in the tube 80, which not only makes it possible to save considerable space relative to two parallel and non-coaxial tubes, but also allows guiding of the water streams with the lowest possible head losses, in light of the arrangement of the various feeds, inlets and outlets of the mixer tap 1.

In a variant, it is possible to provide that the secondary tubes are parallel and not coaxial.

Whatever the variant, the end along the direction R13 of each tube 70 and 80 is respectively connected to the inlets 54 and 78, without meeting of the water streams circulating in the tube 80 outside the tube 70 and the water stream circulating in the tube 70.

In the present example, as visible in particular in figure 3, the secondary part 50 also comprises two axially rectilinear pipes 72. Each rectilinear pipe 72 extends parallel to, and radially at a distance from, the axis X13, while extending along, radially outside, the tube 70. In the present example, around the axis X13, the pipes 72 are distributed in a diametrically opposite manner. Around the axis X13, the pipes 72 are distributed alternating with the pipes 66, as shown in particular in figure 2.

In the direction R13, each rectilinear pipe 72 extends up to the tube 80 and is connected to this tube 80 in the direction R13. In the direction R15, each rectilinear pipe ends with an end emerging axially at the height of the inlet 54, the core 52 or the adjuster 56. These ends emerging along the direction R13 of the pipes 72 form a secondary water inlet 78 of the module 15.

More generally, the module 15, and in particular the part 50, comprise a secondary inlet 78, comprising one or several orifices, preferably formed at the respective end of one or several pipes such as the pipes 72 of the present example.

In the present example, each pipe 72 extends from the inlet 78 to the tube 80, such that each pipe 72 connects the inlet 78 to the tube 80.

As a result, the inlet 78 of the module 15 is connected to the inlet 23 of the module 13 by means of a telescoping tube, formed by the tubes 40 and 80.

The secondary part 50 comprises a connector for connecting the inlet 78 to the feed 6. In the present example, this connector comprises a pair of secondary collars 84, which are radial and external, formed at the radial periphery of the core 52. Each collar 84 is in fight contact, radially outwardly, with the inner wall 9 of the body 2 over an entire perimeter of the inner wall 9 around the axis X2. In the present example, each collar 84 is in tight contact along a circle with the inner wall 9, this circle being coaxial to the axis X2. Advantageously provided, for each collar 84, is a tight fitting providing the radial seal between the wall 9 and the collar 84. The collars 84 are axially spaced apart from one another, while being positioned axially on either side of the orifices forming the inlet 78 and the feed 6. In particular, one of the collars 84 is located at the axial height of the end along the direction R15 of the pipes 72, or the axial height of the inlet 54. The other collar 84 is in the direction R15 relative to the collar 84 previously mentioned, axially past the openings forming the inlet 78, for example the axial height of the end along the direction R15 of the core 52. An outer wall of the core 52, the pipes 66, the inner wall 9 and the collars 84 thus delimit a water intake volume 86, called "secondary volume", in ring form, in which both the feed 6 and the inlet 78 emerge. Thus, the water coming from the feed 6 can only reach the inlet 78, one of the collars 84 preventing the water from progressing in the direction R13 and spreading in the body 2, the other of the collars 84 preventing the water from progressing in the direction R15 and escaping outside the body 2 through the opening 11.

Advantageously, the interior volume of the body 2 is axially tightly closed off by a subassembly including the part 50 and the adjuster 56, at each collar 84.

In the configuration of the figures, the inlet 78 is thus connected to the feed 6.

The secondary volume 86 arranged between the collars 84 makes it possible for the internal assembly to be suitable for being mounted within several different tubular bodies, in particular when the geometry of these tubular bodies differs. The secondary volume 86 is suitable for connecting the inlet 78 to a liquid feed of the tubular body, in different axial positions along the body axis, and in any angular position around the body axis. For example, in the second embodiment illustrated in figure 5, the axial position of a water feed 106 of the body 102 differs relative to that of the feed 6 of the tubular body 2. In particular, relative to the feed 6, the feed 106 is offset in the direction R13. Despite this shift, as long as the feed 106 emerges in the secondary volume 86, the collars 84 ensure the connection between the feed 106 and the inlet 21. The internal assembly is thus particularly versatile and is suitable, without modification of its structure, for several tubular mixer tap bodies, with different geometries. The cumulative presence of two pairs of collars 38 and 84 makes the internal assembly suitable for several tubular mixer tap bodies, the axial gap of which is different from one tubular body to the other. The cumulative presence of two pairs of collars 38 and 84 makes the internal assembly suitable for several tubular mixer tap bodies, for which an angle, defined around the body axis between both feeds, differs.

The module 15 comprises a nut 90 for performing axial fastening of the module 15 relative to the body 2. This nut 90 therefore has a secondary fastening function of the module 15 relative to the body 2. The nut 90 is coaxial with the axis X13 and is located at an axial end of the module 15 in the direction R15. Reciprocally, the body 2 comprises an inner thread 92, provided at the opening 11, in which the nut 90 can be screwed. The nut 90 is advantageously attached against an axial surface of the core 52, facing in the direction R15. Another axial surface of the core 52, facing in the direction R13, in turn bears against an axial shoulder 94 formed on the inner wall 9 of the body 2, such that the axial fastening of the module 15 is obtained by axial interposition of the part 50 between the shoulder 94 and the nut 90. The thread 92 and the shoulder 94 have an anchoring member function of the module 15 relative to the body 2.

In place of the nut 90, the thread 92 and the shoulder 94, any other anchoring members and fasteners can be provided without going beyond the scope of the invention, for example a resilient washer system cooperating with a radial groove arranged hollowed out in the inner wall 9.

Preferably, the two anchoring members are distributed along the axis X2, while respectively being positioned, advantageously, axially near the ends 3 and 4. The primary fastener is borne by the primary module 13, while the secondary fastener is borne by the secondary module 15, such that these fasteners are distributed along the axis X13.

In the present example, the tubes 40 and 42, as well as the tubes 80 and 70, form a coupler of the internal assembly, which is axially telescoping. This coupler connects the outlet 25 with the inlet 54 and connects the inlet 78 with the inlet 23, that is to say, the coupler connects the various inlets and outlets, respectively of the liquid network to be formed within the internal assembly. Owing to the sliding fitting, along the axis X13, of the pair of tubes 40 and 42 with the pair of tubes 80 and 70, the axial distance of the module 13 relative to the module 15 can be modified by axial sliding. The coupler indeed authorizes an axial sliding of the module 13 relative to the module 15, along the directions R13 and R15. In particular, it is possible to modify the relative axial position of the modules 13 and 15 by relative sliding, in order to adapt the same internal assembly to several tubular bodies with different geometries. In particular, this particularly makes it possible to adapt the position of two modules 13 and 15 in the tubular body relative to the position of the liquid feeds. The coupler makes it possible for the sliding of the module 13 relative to the module to be done while the outlet 25 stays connected with the inlet 54 and while the inlet 78 stays connected with the inlet 23. For example, in the case of the third embodiment of figure 6, the same internal assembly as that of figures 1 to 5 has been installed within a tubular body 202 whose geometry differs relative to the tubular bodies 2 and 102: the axial distance along the body axis X202 between the ends 203 and 204 of the body 202 has been increased relative to that of the ends 3 and 4 of the body 2, the ends 203 and 204 respectively being comparable to those of the ends 3 and 4. Likewise, the axial distance along the axis X202 between the liquid feeds 205 and 206 of the body 202 has been increased relative to that of the liquid feeds 5 and 6 of the body 2. In other words, relative to the end 3 and the feed 5, the end 203 and the feed 205 have been shifted along the direction R13. In order to adapt to this axially more extended geometry of the body 202, and in order for the inlets 21 and 78 to be suitably connected respectively to the feeds 205 and 206, the modules 13 and 15 have been axially separated from one another owing to sliding of the coupler connecting them.

Preferably, the coupler is configured so that the sliding of the primary module 13 relative to the secondary module 15 is done over a travel of at least 20 millimeters, preferably 40 millimeters, along the sliding axis X13. Over all of this travel, the primary outlet 25 stays connected with the subsidiary inlet 54 and the secondary inlet 78 stays connected with the auxiliary inlet 23, such that the internal assembly ensures a normal operation, in which the internal assembly generates a stream of water, obtained at the outlet 25, by mixing of the two streams of water supplied to the inlets 21 and 78, with flow rate and temperature control. In a variant, it is possible to provide that the travel is only at least 10 millimeters.

The internal assembly forms a secure assembly of the two modules 13 and 15 by means of the coupler, such that the internal assembly, when it is separated from the body 2, can be manipulated in one piece. The coupler nevertheless allows a separation of the modules 13 and 15, allowing an independent manipulation of these two modules 13 and 15, which facilitates the assembly of the mixer tap 1.

In the preferred example where the tubes 40, 42, 70 and 80 are cylindrical with a circular base, axially rectilinear and coaxial, the coupler allows, aside from the sliding, a relative rotation of the modules 13 and 15 around the sliding axis X13. It is therefore possible to perform a rotation of the module 15 relative to the module 13, by means of the coupler, while the connections of the different inlets and outlets are still provided by the latter. It is advantageously possible to orient the modules 13 and 15 separately relative to one another in the tubular body of the mixer tap, for example in order to ensure that the orifice(s) of the inlet 21 and the inlet 78 are located as close as possible to their respective liquid feeds of the tubular body, around the body axis. This makes it possible to optimize the circulation of the liquid streams while reducing head losses.

A fastening of the modules 13 and 15 to the tubular body by means of primary and secondary fasteners, cooperating with the primary and secondary anchors, makes it possible to fix the relative axial, and optionally angular, position of the modules 13 and 15 relative to the axis X13.

The outlet 64 of the module 15 pouring the liquid directly into the inner volume of the tubular body of the mixer tap, axially between the collar 84 with direction R13 and the collar 38 with direction R15, the internal assembly is adapted to any mixer tap body whose outlet(s) is(are) axially located between the two feeds, irrespective of the position of the outlet(s) in this range. Furthermore, the hot water and the cold water circulate inside pipes, in particular the tubes 40, 42, 70 and 80, which are surrounded by water of average temperature, depending on the adjustment of the mixer 17, such that the contact surface between the hot water and the cold water with the body 2 is minimal: in the case at hand, this contact surface is limited to the parts of the body 2 that are axially located on the one hand between the pair of collars 38 and on the other hand between the pair of collars 84. As a result, from the outside, the mixer tap 1 comprises few hot parts and cold parts that are accessible to the user. Thus, the risk of burn in case of hot parts is particularly limited, the body 2 essentially being at the temperature of the stream emitted by the outlet 64. The generation of condensation by the cold and hot parts on the outer surface of the mixer tap 1 is limited, the body 2 being essentially at the temperature of the water stream emitted by the outlet 64.

In the configuration illustrated in figures 1 to 4, the module 13 has been mounted in the body 2 by means of the opening 10, by axial translation in the direction R15 of the module 13 relative to the body 2. It is advantageously provided that the opening 10 has an appropriate size and geometry to allow such a mounting mode.

In the configuration illustrated in figures 1 to 4, the module 15 has been mounted in the body 2 by means of the opening 11, by axial translation in the direction R13 of the module 15 relative to the body 2. It is advantageously provided that the opening 11 has an appropriate size and geometry to allow such a mounting mode.

In order to assemble the mixer tap 1, it is therefore possible to mount the module 13 via the end 3 on the one hand and the module 15 via the end 4 on the other hand.

In order to ensure all of the aforementioned advantages and technical effects, the internal assembly of the present example includes a reduced number of elements, which makes it especially easy to manufacture and assemble: excluding sealing gaskets, the only primary elements are the mixer 17, the adjuster 56, the parts 30 and 50, the nuts 44 and 90, the tube 42, which makes a total of fewer than ten elements to be assembled. For example, a partial or full assembly of the mixer tap is made possible on the installation site of the mixer tap, rather than on the manufacturing site.

The internal assembly of figures 1 to 6 is configured to adopt a configuration, corresponding to that illustrated in figures 1 to 6, called "direct configuration". In this direct configuration, as illustrated in figures 1 to 4, the primary module is mounted within the body 2 axially on the side of the end 3, such that the inlet 21 is connected to the feed 5, while the module 15 is mounted within the tubular body axially on the side of the end 4, such that the inlet 78 is connected to the feed 6.

This same internal assembly is configured to transition between the direct configuration and a so-called "indirect" or "symmetrical" configuration, in which the modules 13 and 15 are reversed. In this indirect configuration, not shown, the module 13 is mounted within the body 2 on the side of the end 4, such that the inlet 21 is connected to the feed 6 instead of the feed 5, while the module 15 is mounted within the body 2 on the side of the end 3, such that the inlet 78 is connected to the feed 5 instead of the feed 6. It is therefore possible to reverse the internal assembly in the body 2. For example, in the case where the direct configuration corresponds to a situation where the mixer tap 1 is designed to receive cold water at the feed 5 and hot water at the feed 6, whereas in the case at hand, the installation supplies hot water at the feed 5 and cold water at the feed 6, it is possible to modify the mixer tap 1 easily, in particular in the installation site of the mixer tap 1, by transitioning it to the indirect configuration, such that the mixer tap becomes able to receive hot water at the feed 5 and cold water at the feed 6. Owing to these two configurations, it is not necessary to modify the installation, a transition from one configuration of the mixer tap 1 to the other being possible to address the problem.

It will be noted that advantageously, it is possible to transition from the direct configuration to the indirect configuration, and vice versa, while the body 2 remains fastened to the plumbing installation, or to the wall, on which the mixer tap is fastened.

To transition from the direct configuration to the indirect configuration, and vice versa, the modules 13 and 15 are disassembled from the body 2 and remounted in an interverted manner.

To allow the passage from one configuration to the other, it is in particular provided that the nut 44, forming the primary fastener, can be fastened alternatively: - to the thread 46, belonging to the first anchoring member, in the direct configuration, and -to the thread 92, belonging to the second anchoring member, in the indirect configuration.

Likewise, the nut 90, forming the secondary fastener, can alternatively be fastened: - to the thread 46, belonging to the first anchoring member, in the indirect configuration, and -to the thread 92, belonging to the second anchoring member, in the direct configuration.

In order to allow the transition from one configuration to the other, it is in particular provided that the thread 46 and the shoulder 48, or any anchoring member, advantageously have an arrangement symmetrical to the thread 92 and the shoulder 94, or any anchoring member, relative to a plane orthogonal to the axis X2. The nut 44, or any primary fastener, and the nut 90, or any secondary fastener, advantageously have a symmetrical arrangement relative to a plane orthogonal to the axis X13. In other words, the primary and secondary fasteners are interchangeable in their relationship with the two anchoring members, as a function of the direct and indirect configuration adopted by the mixer tap 1.

To allow the transition from one configuration to the other, it is advantageously provided that each opening 10 and 11 allows the introduction, within the body 2, of the module 13 and the module 15 using it.

To allow the transition from one configuration to the other, it is advantageously provided that the inner wall 9 of the body 2 is symmetrical relative to an orthogonal plane with respect to the axis X2. It is advantageously possible to provide that the feeds 5 and 6 also have such a symmetry.

To allow the transition from one configuration to the other, it is advantageously provided that the pairs of collars 38 and 84 have a geometry that makes them interchangeable in their connection with the feeds 5 and 6. For example, the pair of collars 38 is identical or symmetrical, relative to a plane orthogonal to the sliding axis, relative to the pair of collars 84. Thus, each inlet 21 and 78 can be connected either to the feed 5 or to the feed 6, by means of its respective pair of collars 38 or 84, as a function of the direct or indirect configuration.
