Description

Title of the invention: Internal assembly base module and associated sanitary tap

[0001] The present invention relates to a base module for a sanitary tap, an internal assembly comprising such a base module, and a sanitary tap comprising such an internal assembly.

[0002] FR3050512A1 describes a mixing unit for a mixer tap. This unit The mixing unit comprises a mixing chamber with an inlet for a cold water supply and an inlet for a hot water supply. The mixing unit also includes an outlet for a mixed water supply. The mixing unit includes ceramic disc mixing means for blending the two inlet supplies to form the outlet supply. These mixing means are contained within the mixing chamber. The unit also includes an additional housing extending from the mixing chamber. The mixing unit incorporates thermostatic means, mounted within the additional housing, for closing one of the two inlets—namely, the hot water inlet—when the temperature of the mixed water supply exceeds a certain threshold. This additional housing thus prevents a user from being scalded by excessively hot mixed water.

[0003] For certain sanitary installations, particularly in healthcare facilities such as hospitals, it may be necessary to provide a function for disinfecting the mixing unit inside the faucet. One solution for this purpose is to circulate very hot water through the mixing unit. However, the presence of the additional anti-scalding device prevents the implementation of this thermal disinfection function, since, by allowing a flow of hot water for disinfection, the thermostatic means close the hot water inlet and therefore only allow the circulation of hot disinfection water for the cold water inlet.

[0004] Therefore, one of the aims of the invention is to provide a base module with an anti-burn function which is compatible with thermal disinfection.

[0005] To this end, the invention relates to a base module for a sanitary tap, the base module comprising:

[0006] - a base body, which comprises:

[0007] • a lower extremity, traversed by a main axis,

[0008] • an upper end, through which the main axis passes and opposite the end lower part of the base body,

[0009] • a base housing, arranged between the lower end and the upper end of the base body,

[0010] • a hot water inlet at the base, formed at the lower end of the body base,

[0011] • a hot water outlet at the base, formed at the upper end of the body base, the base hot water inlet leading to the base hot water outlet;

[0012] - a shutter, arranged inside the base body and movable relative to the base body between:

[0013] • an open position, where the shutter connects the hot water inlet from the base to the hot water outlet at the lower unit, so that a flow of hot water admitted at the hot water inlet at the lower unit can flow to the hot water outlet at the lower unit, and

[0014] • a safety position, where the shutter separates the hot water inlet from the base and the hot water outlets from the lower unit are positioned to severely restrict the flow of hot water admitted to the lower unit's hot water inlet and flowing to the lower unit's hot water outlet; and

[0015] - a thermoactuator, attached to the base body by being partially housed in the base housing, the thermoactuator comprising a thermosensitive part protruding from the base body in an outlet passage delimited by the base body, the thermoactuator being configured to actuate the shutter from the open position to the safety position when the temperature of the thermosensitive part exceeds a predetermined threshold;

[0016] in which the base body includes an auxiliary hot water inlet formed at the lower end of the base body and opening into the base housing to lead to the hot water outlet of the base via the base housing and thus be connected to the hot water outlet of the base, whether the shutter is in the open position or in the safety position.

[0017] One idea underlying the invention is that, in normal operation of the sanitary tap, the thermo-actuator and the valve provide an anti-scalding function in that, when the temperature of the heat-sensitive part exceeds the threshold, the flow of hot water admitted to the main hot water inlet is interrupted or circulates at a greatly reduced flow rate to the main hot water outlet. In this normal operation, the auxiliary hot water inlet is not intended to be supplied. Another idea underlying the invention is that, to perform thermal disinfection, both the main hot water inlet, with a first portion of the hot water flow, and the auxiliary hot water inlet, with a second portion of the hot water flow, are supplied simultaneously.So, either the first part and the second part of the hot water flow reach the base hot water outlet, if the valve is in the open position, or at least the second part of the hot water flow reaches the base hot water outlet, if the valve is in the safety position, interrupting or reducing. The flow rate of the first part of the hot water stream. The second part of the hot water stream, passing through the base housing, also effectively disinfects the thermoactuator. This second part of the hot water stream is thus likely to pass through areas prone to water stagnation, which, in the prior art, are not always disinfected.

[0018] According to other advantageous aspects of the invention, the invention comprises one or more of the following features, taken individually or in all technically possible combinations:

[0019] - The base housing comprises a first end and a second end opposite and is crossed from the first end to the second end by a housing axis, which is transverse with respect to the main axis.

[0020] - The base housing opens to the outside of the base body at the second end, at the exit passage.

[0021] - The heat-sensitive part is housed in the base housing so as to seal the second end and in such a way that the heat-sensitive part protrudes into the outlet passage.

[0022] - The auxiliary hot water inlet opens into the base housing along the thermoactuator, between the first end and the second end.

[0023] - The hot water outlet from the base opens into the base housing

[0024] - Along the housing axis, the outlet of the base hot water outlet is arranged between the auxiliary hot water inlet and the first end.

[0025] - The outlet of the hot water outlet from the base into the base housing is arranged between the upper end of the base body and the housing axis.

[0026] - The hot water inlet at the base opens into the base housing at the first end.

[0027] - The base body includes a collar, arranged in the base housing so as that the hot water inlet from the base leads to the hot water outlet from the base via the base housing, through the neck and the auxiliary hot water inlet leads to the hot water outlet from the base via the base housing without passing through the neck.

[0028] - The shutter is arranged in the base housing.

[0029] - In the open position, the obturator is recessed relative to the neck, so as not to do not block the neck, thus connecting the base hot water inlet and the base hot water outlet.

[0030] - In the safety position, the obturator comes to rest against the neck to separate the hot water inlet and hot water outlet of the base from each other, or to greatly limit the flow of hot water admitted to the hot water inlet of the base and flowing to the hot water outlet of the base.

[0031] - The neck is arranged at the base hot water inlet.

[0032] - The base module includes a lower sealing gasket, which is coaxial with the main axis, which is arranged around the lower end of the base body.

[0033] - The lower unit body includes a mixed lower unit water inlet, formed at the lower end of the base body and a mixed base water outlet, formed at the upper end of the base body, the mixed base water inlet leading to the mixed base water outlet without passing through the base housing, to be connected to the mixed base water outlet, whether the shutter is in the open position or in the safety position.

[0034] The invention also relates to an internal assembly comprising: • the base module as described above; and • a derivative module, comprising: • a derivative body, comprising: • a lower end, which is traversed by the main axis, and • a diverter hot water inlet, formed at the lower end of the diverter body and configured to be fluidly connected to a hot water pipe, • an upper end, which is traversed by the main axis and which is opposite the lower end of the derivative body, • a diverter hot water outlet, formed at the upper end of the diverter body and fluidly connected to the base hot water inlet, • an auxiliary hot water outlet, formed at the upper end of the diverter body and fluidically connected to the auxiliary hot water inlet; and • a mechanical selector, arranged inside the derivative body between the upper and lower ends of the derivative body and capable of moving between: • a main configuration, where: • The diverter's hot water inlet is connected to the diverter's hot water outlet, so that a flow of hot water admitted into the diverter body at the diverter's hot water inlet can flow to the diverter's hot water outlet, and • The mechanical selector separates the auxiliary hot water outlet from the diverter hot water inlet. so that the flow of hot water thus admitted does not reach the auxiliary hot water outlet via the mechanical selector; and • a thermal disinfection setup, where: • The diverter's hot water inlet is connected to the diverter's hot water outlet so that a first portion of the admitted hot water flow can reach the diverter's hot water outlet, and • The mechanical selector connects the diverter hot water inlet to the auxiliary hot water outlet, so that a second part of the hot water flow admitted into the diverter body at the diverter hot water inlet can flow to the auxiliary hot water outlet, the second part of the hot water flow then being admitted into the base housing through the auxiliary hot water inlet so that it can flow to the base hot water outlet by passing along the thermoactuator in the base housing.

[0035] According to additional advantageous features of the assembly according to the invention, taken individually or in all possible combinations:

[0036] - The diverter body includes an ambient diverter water inlet, formed at the lower end of the diverter body and configured to be fluidly connected to an ambient water line, a diverter mixed water outlet, formed at the upper end of the diverter body and fluidly connected to a base mixed water inlet.

[0037] - In the main configuration, the mechanical selector connects the water inlet ambient water from the diverter to the diverter mixed water outlet, so that an ambient water flow admitted into the diverter body at the diverter ambient water inlet can flow to the diverter mixed water outlet; the mechanical selector separates the diverter ambient water inlet from the auxiliary hot water outlet and the diverter hot water outlet, so that the ambient water flow thus admitted does not reach the auxiliary hot water outlet and the diverter hot water outlet, and the mechanical selector separates the diverter hot water inlet and the diverter mixed water outlet from each other, so that the hot water flow thus admitted does not reach the diverter mixed water outlet.

[0038] - In thermal disinfection configuration, the mechanical selector separates the inlet ambient water from the diverter, the mixed water outlet from the diverter, the hot water outlet from the diverter, and the auxiliary hot water outlet, so that the flow ambient water at the diverter ambient water inlet is interrupted, and the mechanical selector connects the diverter hot water inlet to the diverter mixed water outlet so that a third part of the hot water flow thus admitted can flow to the diverter mixed water outlet.

[0039] - The internal assembly further includes a mixing cartridge, comprising: • a cartridge body, comprising: • a lower end; • a cartridge mixed water inlet, formed at the lower end of the cartridge body, the base mixed water outlet being fluidly connected to the cartridge mixed water inlet, • a cartridge hot water inlet, formed at the lower end of the cartridge body, the cartridge hot water inlet being connected to the base hot water outlet, and • a mixed water outlet, formed at the lower end of the cartridge body; • a control element, movable relative to the cartridge body; and • a ceramic disc mixer, through which the mixed water inlet from the cartridge and the hot water inlet from the cartridge lead to the mixed water outlet, a ceramic disc of the disc mixer being movable relative to the cartridge body under the action of the control element to adjust: • the value of a proportion between a flow rate of a first water flow admitted into the cartridge body at the cartridge's mixed water inlet and a flow rate of a second water flow admitted into the cartridge body at the cartridge's hot water inlet, in the formation of a mixed water flow in the cartridge body by mixing the first water flow and the second water flow, the mixed water flow being discharged at the mixed water outlet, and • the value of the mixed water flow rate.

[0040] The invention also relates to a sanitary tap, comprising a tap body and the internal assembly as described above, received inside the tap body.

[0041] The invention will become clearer upon reading the following description, given solely by way of non-limiting example, and made with reference to the drawings in which:

[0042] [Fig-1] [Fig.1] is a longitudinal cross-sectional view of a sanitary tap according to a method of embodiment of the invention.

[0043] [Fig.2] [Fig.2] is a perspective view of an internal assembly belonging to the sanitary tap of [Fig.1], seen from three-quarter angle.

[0044] [Fig.3] [Fig.3] is a rear view of the internal assembly of [Fig.2].

[0045] [Fig.4] [Fig.4] is a partial longitudinal cross-sectional view of the sanitary tap of the previous figures, following a radial section plane IV-IV shown in [Fig.1], a derivatizing module belonging to the internal assembly being in a principal configuration.

[0046] [Fig.5] [Fig.5] is a view similar to that of [Fig.4], where the differentiator module is in a transient configuration.

[0047] [Fig.6] [Fig.6] is a view similar to those of Figures 4 and 5, where the derivatizer module is in a thermal disinfection configuration.

[0048] [Fig.7] [Fig.7] is a partial longitudinal cross-sectional view of the sanitary tap of the previous figures, following another cutting plane radially passing through a thermoactuator belonging to the internal assembly.

[0049] Figures 1 to 7 relate to a sanitary tap according to an embodiment of the invention. The sanitary tap is preferably intended for use in a healthcare facility, such as a hospital, or any location where the possibility of thermal disinfection of the sanitary tap might be desired.

[0050] The sanitary tap comprises a tap body 1, including a main part 2 and a spout 3. By means of the main part 2, the sanitary tap is intended to be fixedly mounted on a sink, washbasin, or other similar sanitary basin, or on a wall adjacent to said sanitary basin, the sanitary basin being intended to receive a mixed water flow M3 delivered by the spout 3 of the sanitary tap. The mixed flow M3 is formed inside the main part 2 by mixing a flow of ambient water A3 and a flow of hot water C3, supplied to the sanitary tap respectively by an ambient water pipe 4 and a hot water pipe 5, visible in [Fig. 2]. The ambient water is sometimes referred to as cold water, in that it is supplied at a lower temperature than the hot water.Ambient water is supplied at ambient temperature, for example between 5 and 30 °C depending on the season, whereas hot water is ambient water that has been specifically heated using a domestic hot water heating system, for example a boiler or a hot water tank, to be supplied at a temperature between 40 and 85 °C.

[0051] Preferably, as shown in [Fig. 1], the main part 2 is tubular in shape, here with a circular cross-section, centered on a main axis Z2. The main axis Z2 is intended to be vertical when the sanitary tap is installed, but an oblique orientation relative to the vertical could be provided, depending on the shape of the tap body 1, for technical and / or aesthetic reasons. The The tap body 1 is fixedly mounted on the sanitary basin or the adjacent wall by means of a lower end 6 of the main part 2, through which the main axis Z2 passes. The main part 2 is open at the lower end 6, so that the main part 2 can receive a respective end of the pipes 4 and 5 through the lower end 6, as shown in figures 1 and 4 to 6.

[0052] Preferably, the main part 2 also includes an upper end 7, also open, through which the axis Z2 passes and which is opposite the lower end 6. As shown in [Fig. 1], the spout 3 projects laterally from the main part 2, between the ends 6 and 7. The main part 2 internally delimits an outlet chamber 9, between the ends 6 and 7, into which the interior of the spout 3 opens, so that the outlet chamber 9 leads to the spout 3, and in particular to a mixed water outlet 8 belonging to the spout 3. The mixed water flow M3, formed in the outlet chamber 9, flows from said lower chamber to the outlet 8 via the spout 3. The outlet 8 is located away from the main part 2.

[0053] The sanitary tap includes an internal assembly, which is received inside the main part 2 of the tap body 1. The internal assembly includes a diverter module 20, a base module 50 and a mixing cartridge 80. Preferably the module 20, the module 50 and the cartridge 80 are arranged successively in this order along the axis Z2, the diverter module 20 being arranged on the side of the lower end 6 while the cartridge 80 is arranged on the side of the upper end 7.

[0054] The derivatization module 20 comprises a derivatization body 21, which includes a lower end 22 and an upper end 23 opposite and traversed by the main axis Z2.

[0055] The base module 50 comprises a base body 51, which includes a lower end 52 and an upper end 53 opposite and traversed by the main axis Z2.

[0056] The cartridge 80 comprises a cartridge body 81, which includes a lower end 82 through which the main axis Z2 passes.

[0057] Preferably, the diverter module 20 is supported against the base module 50 along the main axis Z2 by the upper end 23 being supported against the lower end 52 along the axis Z2. The ends 23 and 52 preferably have anti-rotation elements, such as pins and orifices, so that they can be supported against each other along the axis Z2, in a single orientation relative to each other around the axis Z2, ensuring the alignment of the water inlets and outlets of the modules 20 and 50, defined below, for the fluidic connection of these inlets and outlets. The ends 23 and 52 thus constitute interfaces.

[0058] Preferably, the base module 50 bears against the mixing cartridge 80 along the main axis Z2, by bringing its upper end 53 against its lower end 82 along the axis Z2. The base module 50 is thus interposed between the cartridge 80 and the diverter module 20 along the axis Z2. Therefore, the diverter module 20, the base module 50, and the cartridge 80 each constitute a separable subassembly from the other two. Ends 23 and 52 preferably include anti-rotation elements, such as pins and orifices, so that they can be supported against each other along axis Z2, with a single orientation relative to the other around axis Z2. This ensures the alignment of the water inlets and outlets of module 50 and cartridge 80, as defined below, for the fluidic connection of these inlets and outlets. Ends 53 and 82 then constitute interfaces.

[0059] In addition to the delimitation of chamber 9 by the main part 2 of the valve body 1, the internal assembly also delimits chamber 9. The internal assembly traverses chamber 9 axially along axis Z2, so that chamber 9 is delimited radially between the internal assembly and the main part 2. Chamber 9 therefore advantageously has an annular, or portion-of-a-ring, shape inside the main part 2 and around the internal assembly. Along axis Z2, chamber 9 is delimited by a lower sealing gasket 78 and an upper sealing gasket 79. Each sealing gasket extends over the entire external circumference of the internal assembly, around axis Z2, and over the entire internal circumference of the main part 2 of the valve body 1.

[0060] The opening of the spout 3 in the main part 2 of the tap body 1 is arranged between the sealing gaskets 78 and 79, so that the spout 3 opens into the chamber 9.

[0061] Preferably, the upper sealing gasket 79 is arranged at the height of the cartridge body 81, beyond the lower end 82 opposite the module 50, so as to radially connect the body 81 to the main part 2 of the valve body 1. The sealing gasket 79 is for example carried by the cartridge body 81 and in water-sealing contact against the inside of the part 2.

[0062] Preferably, the lower sealing gasket 78 is arranged at the height of the base body 51, or of the diverter body 21, at the height of the lower end 52 or beyond the lower end 52 opposite the cartridge 80, so as to radially connect the body 51 or the body 21 to the main part 2 of the valve body 1. Preferably, the gasket 78 is positioned at the height of the lower end 52. The sealing gasket 78 is, for example, supported by the base body 51 and is in watertight contact against the inside of the part 2.

[0063] The derivative module 20 is described in more detail below.

[0064] As shown in figures 4 to 6, the lower end 22 is preferably arranged inside the main part 2 by being turned towards the lower end 6. In any case, the lower end 22 is provided to face the conduits 4 and 5 in order to connect to them.

[0065] The diverter body 21 includes an ambient water inlet 24, referred to as the "diverter ambient water inlet," which opens at its lower end 22. The downward-facing ambient water inlet 24 connects to the ambient water line 4. To this end, the ambient water inlet 24 preferably constitutes a complementary connecting element with the upper end of the line 4, for a leak-proof fluid connection between the ambient water inlet 24 and the line 4. Preferably, a seal is provided at the interface between the line 4 and the inlet 24. In any case, the ambient water flow A3 supplied by the ambient water line 4 can be admitted into the body 21 via the ambient water inlet 24, without leaking into the main part 2 of the body 1 via the connection between the line 4 and the inlet 24. Preferably, a means for fixing the line 4 to the diverter body 21 is provided, for example a stirrup or a pin.

[0066] The diverter body 21 includes a hot water inlet 25, referred to as the "diverter hot water inlet," which opens at the lower end 22. The downward-facing hot water inlet 25 connects to the hot water pipe 5. To this end, the hot water inlet 25 preferably constitutes a complementary connection element with the upper end of the pipe 5, for a leak-proof fluid connection between the hot water inlet 25 and the pipe 5. Preferably, a seal is provided at the interface between the pipe 5 and the inlet 25. In any case, the hot water flow C3 supplied by the hot water pipe 5 can be admitted into the body 21 via the hot water inlet 25, without leaking into the main part 2 of the body 1 via the connection between the pipe 5 and the inlet 25. Preferably, a means for fixing the pipe 5 to the diverter body 21 is provided, for example a stirrup or a pin.

[0067] Preferably, on the end 22, the inlets 24 and 25 are distributed diametrically on either side of the axis Z2.

[0068] Preferably, no water inlet and no water outlet other than inlets 24 and 25 is provided at the lower end 22.

[0069] The upper end 23 is inside the main part 2, facing the upper end 7. Preferably, the upper end 23 is arranged between the lower end 6 and the outlet chamber 9.

[0070] The diverter body 21 includes a mixed water outlet 26, referred to as the "diverter mixed water outlet", a hot water outlet 27, referred to as the "diverter hot water outlet", and an auxiliary hot water outlet 28. The outlets 26, 27, and 28 open at the upper end 23, facing the end 7, i.e., upwards. The outlets 26 and 28 are visible in Figures 4 to 6, while the outlet 27 is visible in [Fig.7]. Preferably, no water inlets or outlets other than outlets 26, 27 and 28 are provided at the upper end 23. Preferably, no water inlets or outlets other than those mentioned above for the diverter body 21 are provided for the diverter module 20.

[0071] The base body 51 includes a mixed water inlet 54, referred to as the "base mixed water inlet," a hot water inlet 55, referred to as the "base hot water inlet," and an auxiliary hot water inlet 59. The inlets 54, 55, and 59 open at the lower end 52, facing the end 6, i.e., downwards. The inlets 54 and 59 are visible in Figures 4 to 6, while the inlet 55 is visible in [Fig. 7]. Preferably, no water inlets or outlets other than the inlets 54, 55, and 59 are provided at the lower end 52.

[0072] As shown in figures 4 to 6, the mixed water outlet 26 is connected to the mixed water inlet 54. To this end, the supports of the ends 23 and 52 are made with the outlet 26 aligned with the inlet 54. A seal of this connection is advantageously ensured by a gasket surrounding the outlet of the outlet 26 on the end 23 or of the inlet 54 on the end 52, and interposed between the two ends. A water flow exiting body 21 through outlet 26 is admitted into body 51 via inlet 54, without leaking into the main part 2 of body 1 via the connection between outlet 26 and inlet 54. As explained below, depending on the configuration, this water flow is either the ambient water flow A3 from inlet 24, or a part C26 of the hot water flow C3 from inlet 25.

[0073] As shown in [Fig. 7], the hot water outlet 27 is connected to the hot water inlet 55. To this end, the ends 23 and 52 are supported with the outlet 27 aligned with the inlet 55. A seal of this connection is advantageously ensured by a gasket surrounding the opening of the outlet 27 on the end 23 or of the inlet 55 on the end 52, and interposed between the two ends. A flow of water exiting the body 21 through the outlet 27 is admitted into the body 51 via the inlet 55, without leaking into the main part 2 of the body 1 via the connection between the outlet 27 and the inlet 55. As explained below, this flow of water is either the hot water flow C3 or a portion C27 of the hot water flow C3.

[0074] As shown in Figures 4 to 6, the hot water outlet 28 is connected to the hot water inlet 59. To this end, the ends 23 and 52 are supported with the outlet 28 aligned with the inlet 59. A seal of this connection is advantageously ensured by a gasket surrounding the opening of the outlet 28 on the end 23 or of the inlet 59 on the end 52, and interposed between the two ends. A flow of water exiting the body 21 through the outlet 28 is admitted into the body 51 via the inlet 59, without leaking into the main part 2 of the body 1 through the connection between outlet 28 and inlet 59. As explained below, this water flow is part C28 of the hot water flow C3.

[0075] Preferably, on end 23, the outputs 26, 27 and 28 are arranged in a triangle. The inputs 54, 55 and 59 are arranged correspondingly on end 52.

[0076] Preferably, the diverter body 21 forms a diverter housing 30 between the ends 22 and 23, which comprises a first end 31 and a second end 32 opposite each other. The diverter housing 30 is traversed from the first end 31 to the second end 32 by a transverse axis Y30, which is here a diametrical axis with respect to the axis Z2, but which could simply be a transverse axis with respect to the axis Z2, perpendicular or not to the axis Z2, intersecting or not the axis Z2. Preferably, the diverter housing 30 has a shape of revolution centered on the axis Y30.

[0077] Along the Y30 axis, a Y100 direction, called the "direction of actuation", is also defined, which goes from the end 32 to the end 31.

[0078] Along axis Z2, the diverter housing 30 is arranged between inlets 24 and 25 on one side, and outlets 26 and 28 on the other. Inlet 24 opens into the diverter housing 30 at the first end 31. Inlet 25 opens into the diverter housing 30 at the second end 32. Beyond axis Y30 opposite inlets 24 and 25, the diverter housing 30 opens into outlet 26, at an intermediate part of the housing 30 between ends 31 and 32. If outlet 28 is provided, the diverter housing 30 opens into outlet 28, beyond axis Y30 opposite inlets 24 and 25, at an intermediate part of the housing 30 between outlet 26 and end 32.

[0079] The diverter body 21 advantageously comprises a neck 33, arranged between the ends 22 and 23, in the diverter housing 30. The neck 33 is, for example, formed by an internal shoulder preferably coaxial with the axis Y30. Preferably, the neck 33 is frustoconical. Preferably, the neck 33 is formed directly by the wall of the body 21 delimiting the housing 30. Alternatively, the neck 33 is formed by an added piece. Along the axis Y30, the neck 33 is arranged between the opening of the inlet 24 in the diverter housing 30 and the opening of the outlet 26 in the diverter housing 30. Thus, the ambient water inlet of diverter 24 leads to the mixed water outlet of diverter 26 via the housing 30, through the neck 33.

[0080] The diverter body 21 advantageously comprises a neck 34, arranged between the ends 22 and 23, in the diverter housing 30. The neck 34 is, for example, formed by an internal shoulder, preferably coaxial with the axis Y30. Preferably, the neck 34 is frustoconical. Preferably, the neck 34 is formed directly by the wall of the body 21 delimiting the housing 30. Along the axis Y30, the neck 34 is arranged between, on the one hand, the opening of the inlet 25 in the diverter housing 30 and, on the other hand, the outlets of outlets 26 and 28 in the diverter housing 30. In particular, along the Y30 axis, the throat 34 is formed between the inlet 25 and outlet 28. Along the Y30 axis, the throat 34 is formed between the throat 33 and the end 32. In other words, the throat 33 is in the Y100 direction relative to the throat 34. Thus, the hot water inlet of diverter 25 leads to the mixed water outlet of diverter 26 and to the auxiliary hot water outlet 28, via housing 30, through the throat 34.

[0081] The derivat body 21 advantageously comprises a neck 38, arranged between the ends 22 and 23, in the derivat housing 30. The neck 38 is for example formed by an internal shoulder preferably coaxial with the axis Y30. Preferably, the neck 38 is frustoconical. Preferably, the neck 38 is formed directly by the wall of the body 21 delimiting the housing 30. Along the Y30 axis, the neck 38 is arranged between, on the one hand, the openings of the inlet 25 and outlet 28 into the diverter housing 30 and, on the other hand, the opening of the outlet 26 into the diverter housing 30. In particular, along the Y30 axis, the neck 38 is formed between the openings of outlet 26 and outlet 28. Along the Y30 axis, the neck 38 is formed between the neck 33 and the neck 34. Thus, the inlet 24 and outlet 26 can only lead to the inlet 25 and the outlets 27 and 28 through the neck 38.

[0082] Preferably, as more clearly seen in [Fig. 7], the diverter body 21 includes a hot water conduit 35. The hot water conduit 35 connects the inlet 25 to the outlet 27, bypassing the housing 30. Consequently, the hot water inlet of the diverter 25 leads to the hot water outlet of the diverter 27 via the hot water conduit 35 without passing through the housing 30. Similarly, the inlet 25 leads to the housing 30 without passing through the hot water conduit 35. In particular, the inlet 25 leads on one side to the housing 30 via the collar 34, and on the other side to the conduit 35, the division taking place upstream of the collar 34 and even upstream of the housing 30. “Upstream” refers to the direction of water flow from the inlets to the outlets of the body 21.

[0083] The derivation module includes a mechanical selector 100, arranged inside the derivation body 21 between the ends 22 and 23. In particular, the mechanical selector 100 extends at least partially into the housing 30.

[0084] At the command of a technician, the mechanical selector 100 is capable of switching between a main configuration, shown in [Fig. 4], and a thermal disinfection configuration, shown in [Fig. 6]. The selector 100 preferentially passes through a transient configuration, shown in [Fig. 5], when switching from the main configuration to the thermal disinfection configuration and from the thermal disinfection configuration back to the main configuration. These configurations are defined below.

[0085] The mechanical selector 100 preferably comprises a valve 101, a valve 102, an actuating member 103, an overtravel spring 104, a return spring 105 and an actuating head 106, all of which are arranged between the ends 22 and 23.

[0086] The valves 101 and 102 have the function of allowing the selector 100 to reach the main configuration, the thermal disinfection configuration and, if provided, the transitional configuration.

[0087] The valve 101 is arranged inside the housing 30, near the neck 33, preferably between the neck 33 and the neck 34. Preferably, the valve 101 is an annular piece, coaxial with the Y30 axis. The valve 101 is movable, for example, translationally movable along the Y100 direction, relative to the diverter body 21, from a release position where the valve 101 does not obstruct the neck 33, shown in [Fig. 4], to a support position where the valve 101 obstructs the neck 33, shown in Figures 5 and 6. When the valve 101 is in the release position, the valve 101 is at a distance from the neck 33 in the opposite direction to Y100, so as not to obstruct the neck 33. In its support position, the valve 101 bears against the neck 33 in the direction of Y100, so that the valve 101 obstructs the neck 33. Regardless of its position, the valve 101 does not obstruct the necks 34 and 38.

[0088] The valve 102 is arranged inside the housing 30, near the necks 34 and 38, preferably between the neck 33 and the neck 34. Preferably, the valve 102 is an annular piece, coaxial with the axis Y30. The valve 102 is movable, for example movable in translation along the direction Y100, relative to the diverter body 21 from a support position where the valve 102 closes the necks 34 and 38, shown in Figures 4 and 5, to a release position where the valve 102 does not close the necks 34 and 38, shown in [Fig. 6]. When the valve 102 is in the release position, the valve 102 is at a distance from the necks 34 and 38 in the direction Y100, so as not to obstruct the necks 34 and 38. In its resting position, the valve 102 rests against the necks 34 and 38 in the opposite direction to Y100, so that the valve 102 obstructs the necks 34 and 38. Regardless of its position, the valve 102 does not obstruct the neck 33.

[0089] As shown in [Fig. 4], when the selector 100 is in the main configuration, the valve 101 is in the release position. The neck 33 is therefore not closed, which results in the ambient water inlet of diverter 24 being connected to the mixed water outlet of diverter 26 through the neck 33, allowing the ambient water flow A3 to circulate from the inlet 24 to the outlet 26 via the neck 33.

[0090] Regardless of the position of the valves 101 and 102, the hot water inlet of diverter 25 leads to the hot water outlet of diverter 27 via the conduit 35, i.e., upstream of the collar 34, so that the hot water inlet of diverter 25 is connected to the hot water outlet of diverter 27, regardless of whether the selector 100 is in the configuration main, transient or thermal disinfection. In particular, this connection is established independently of the position of valves 101 and 102.

[0091] In the main configuration, the other valve 102 is in the support position. With the valve 102 blocking the neck 34, the housing 30 does not connect the hot water inlet 25 to the outlets 26 and 28 or to the inlet 24, since the inlet 25 leads to the outlets 26 and 28 and to the inlet 24 only through the neck 34. The hot water flow C3 admitted to the inlet 25 cannot then reach the outlets 26 and 28 and the inlet 24. No check valve is required.

[0092] In its main configuration, the valve 102, in its supported position, also closes the neck 38, so that the housing 30 does not connect the inlet 24 and outlet 26 to the outlets 27 and 28 and to the inlet 25. Therefore, there is no risk of the ambient water flow A3 admitted into the body 21 through the inlet 24 reaching the outlets 27 and 28 or even the inlet 25, which are dedicated to hot water. This result is achieved without using a check valve.

[0093] In the main configuration, all the hot water flow C3 admitted at the inlet 25 flows to the hot water outlet 27, without passing through the housing 30 since the valve 102 in the support position closes the neck 34.

[0094] In summary, in the main configuration shown in [Fig. 4], the mechanical selector 100 connects the ambient water inlet of the diverter 24 to the mixed water outlet of the diverter 26 via the housing 30. Through this connection, the ambient water flow A3 admitted into the diverter body 21 at the ambient water inlet of the diverter 24 is allowed and guided to flow to the mixed water outlet of the diverter 26 via the housing 30. In the main configuration, the mechanical selector 100 separates the ambient water inlet of the diverter 24 and the hot water outlet of the diverter 27 from each other, so that the ambient water flow A3 admitted through the inlet 24 does not reach the hot water outlet of the diverter 27.In the main configuration, the hot water inlet of the diverter 25 is connected to the hot water outlet of the diverter 27 via the conduit 35, so that the hot water flow C3 admitted into the diverter body 21 at the hot water inlet of the diverter 25 flows to the hot water outlet of the diverter 27. In the main configuration, the mechanical selector 100 separates the hot water inlet of the diverter 25 and the mixed water outlet of the diverter 26 from each other, so that the hot water flow C3 admitted at the inlet 25 does not reach the mixed water outlet of the diverter 26. In the main configuration, the mechanical selector 100 separates the inlet 24 and the inlet 25 from each other.In the main configuration, the mechanical selector 100 separates the auxiliary hot water outlet 28 from the diverter ambient water inlet 24 and the diverter hot water inlet 25, so that the ambient water flow A3 and the hot water flow C3 admitted by these respective inlets 24 and 25 cannot reach the auxiliary hot water outlet 28.

[0095] The main configuration is used for the normal use of the sanitary tap, and allows normal operation of the sanitary tap where the mixed base inlet 54 receives the flow A3 supplied by the outlet 26 and where the hot water base inlet 55 receives the flow C3 supplied by the outlet 27. In this situation, the auxiliary inlet 59 is not supplied and is even separated from the inlets 24 and 25 and the outlets 26 and 27 by the selector 100, namely preferably by the valve 102.

[0096] As shown in [Fig.5], when the selector 100 is in the transient configuration, if provided, the valves 101 and 102 are both in the support position, thus closing the necks 33, 34 and 38.

[0097] With the neck 33 closed, the inlet 24 is separated from the outlets 26, 27 and 28 and from the inlet 25. The ambient water flow A3 at the inlet 24 is interrupted by the closed neck 33 and therefore cannot reach the outlets 26, 27 and 28 and the inlet 25.

[0098] With the neck 34 closed, the inlet 25 is separated from the outlets 26 and 28 and from the inlet 24. The hot water flow C3 at the inlet 25 cannot therefore reach the outlets 26 and 28 and the inlet 24. However, the hot water flow C3 is not interrupted, since the inlet 25 remains connected to the outlet 27 via the conduit 35. The hot water flow C3 admitted at the inlet 25 is therefore conducted entirely to the outlet 27 via the conduit 35.

[0099] With the necks 33 and 38 being closed, residual ambient water, initially admitted into the body 21 via the inlet 24 while the mechanical selector 100 was in main configuration and which would have accumulated between the two necks 33 and 38, cannot reach the inlet 25 or the outlets 27 and 28.

[0100] In summary, when the mechanical selector 100 is in transient configuration, the mechanical selector 100 separates the ambient water inlet of diverter 24 and the mixed water outlet of diverter 26 from each other, so that the flow of ambient water A3 to the ambient water inlet of diverter 24 is interrupted. In the transitional configuration, the selector 100 also prevents the ambient water flow A3 from reaching the other outlets 27 and 28 and the inlet 25. In the transitional configuration, the diverter hot water inlet 25 remains connected to the diverter hot water outlet 27 via the conduit 35, so that the hot water flow C3 admitted through the inlet 25 flows to the diverter hot water outlet 27. In the transitional configuration, the mechanical selector 100 isolates the diverter hot water inlet 25 from the outlets 26 and 28, so that the hot water flow C3 admitted through the inlet 25 does not reach these outlets 26 and 28.

[0101] The transient configuration is used temporarily when switching from the main configuration to the thermal disinfection configuration and vice versa, to prevent accidental mixing of the water flows A3 and C3 in the body 21. In this transient configuration, it is ensured that the connection of the inlet 25 will be established with the outlets 26 and 28 in the thermal disinfection configuration, only after the inlet 24 has been separated from the outlet 26 during the transient configuration. In this transient configuration, it is ensured that the connection of input 24 will be established with output 26 in the main configuration, only after outputs 26 and 28 have been separated from input 25 during the transient configuration.

[0102] As shown in [Fig. 6], when the selector 100 is in the thermal disinfection configuration, the valve 101 is in the supported position and the valve 102 is in the released position. In the thermal disinfection configuration, the valve 101 in the supported position closes the neck 33 so that the ambient water inlet of the diverter 24 is separated from the outlets 26, 27, and 28, as well as from the inlet 25. Indeed, the inlet 24 can only lead to the outlets 26, 27, and 28 and to the inlet 25 via the neck 33, which is currently closed. The flow of ambient water A3 at the inlet 24 is then interrupted. In thermal disinfection configuration, the valve 102 in the release position does not close the necks 34 and 38, so that the hot water inlet of diverter 25 is connected to the mixed water outlet of diverter 26, but also to the auxiliary hot water outlet 28. The hot water inlet 25 also remains connected to the hot water outlet 27 via the conduit 35.As a result, the hot water flow C3 admitted at inlet 25 is divided into portion C27, which can flow from inlet 25 to outlet 27 via conduit 35; portion C28, which can flow from inlet 25 to outlet 28 via neck 34; and portion C26, which can flow from inlet 25 to outlet 26, successively via neck 34 and neck 38. However, with valve 101 in the closed position to block neck 33, no portion of the C3 flow from inlet 25 can reach inlet 24. When switching from the main configuration to the thermal disinfection configuration, residual ambient water, initially from inlet 24 and which would have accumulated in chamber 30 downstream of neck 33, is then driven by part C26 of the hot water flow C3 towards the outside of body 21 via outlet 26.When switching from the main configuration to the thermal disinfection configuration, residual water, from a previous supply of the base body 51 with the hot water flow C3 while the selector 100 was in the main or transitional configuration, which hot water would have accumulated at the outlet 28, is then expelled by part C28 of the hot water flow C3 to a base housing 60 belonging to the base body 51 and defined below, via the outlet 28.

[0103] In summary, in the thermal disinfection configuration, the mechanical selector 100 separates the ambient water inlet of diverter 24 from the mixed water outlet of diverter 26, the hot water outlets of diverters 27 and 28, and the inlet 25, so that the flow of ambient water A3 to the ambient water inlet of diverter 24 is interrupted. The selector 100 thus prevents the flow of ambient water A3 from reaching the outlets 26, 27, and 28 and the inlet 25. In the thermal disinfection configuration, the hot water inlet of diverter 25 is connected to the mixed water outlet of diverter 26 via selector 100, to the diverter 27 hot water outlet via conduit 35 and to the auxiliary hot water outlet 28 via selector 100. This allows a portion C26 of the hot water flow C3 admitted at the inlet 25 to flow to the diverter 26 mixed water outlet. This allows a portion C27 of the hot water flow C3 to flow to the diverter 27 hot water outlet. This allows a portion C28 of the hot water flow C3 to flow to the auxiliary hot water outlet 28.

[0104] The thermal disinfection configuration is used to perform thermal disinfection of the sanitary tap, in particular of the base module 50 and the cartridge 80, by supplying the three inlets 54, 55 and 59 of the base module 50 with the hot water flow C3. The conduit 35 and the outlet 27 of the diverter module 20 are also disinfected, as well as, downstream of the collar 33, the housing 30 and the outlets 26 and 28.

[0105] The actuating member 103, the head 106 and the springs 104 and 105 have the function of enabling the technician to actuate the valves 101 and 102 by necessarily obtaining the configurations defined above.

[0106] Preferably, the actuating member 103 is received, essentially or entirely, in the housing 30, at least in the main configuration. Preferably, the actuating member 103 comprises a rod 110, advantageously coaxial with the axis Y30, and two shoulders 108 and 109, fixedly mounted on the rod 110 inside the housing 30 and projecting radially from the rod 110. The shoulder 108 is arranged in the Y100 direction relative to the shoulder 109. Alternatively, the shoulders 108 and 109 may be provided that they are not rotationally fixed about the axis Y30 relative to the rod 110.

[0107] The actuating member 103 is movable in translation relative to the body 21, along the Y100 direction, from a main position, shown in [Fig. 4], to a maintenance position, shown in [Fig. 6], passing through an intermediate position, shown in [Fig. 5]. Preferably, the actuating member 103 is also movable in rotation about the Y30 axis relative to the body 21, as explained below.

[0108] The annular valves 101 and 102 are preferably supported by the rod 110 of the component 103, for example by being threaded onto the rod 110. Preferably, a sealing gasket is radially interposed between the valve 101 and the rod 110 to ensure a seal between the valve 101 and the rod 110 at the center of the valve 101. Preferably, a sealing gasket is radially interposed between the valve 102 and the rod 110 to ensure a seal between the valve 102 and the rod 110 at the center of the valve 102. The valves 101 and 102 are arranged between the shoulders 108 and 109. The valve 101 is therefore arranged in the opposite direction to Y100 with respect to shoulder 108, between shoulder 108 and valve 102. Valve 102 is arranged in the Y100 direction by relative to shoulder 109, between shoulder 109 and valve 101. Each valve 101 and 102 is optionally pivoting around axis Y30 relative to member 103, or may be non-pivoting around axis Y30 relative to member 103.

[0109] The valve 101 is movable relative to the member 103, in particular relative to the rod 110, along the direction Y100, until it comes to rest against the nearest element between the shoulder 108 and the neck 33 along the direction Y100. In the opposite direction to the direction Y100, the member 103 drives the valve 101 via the shoulder 108 when the shoulder 108 and the valve 101 are thus in contact with each other parallel to the direction Y100.

[0110] The valve 102 is movable relative to the member 103, in particular relative to the rod 110, along the direction Y100, until it comes to rest against the nearest element among the shoulder 109 and the collars 34 and 38 in the opposite direction to the direction Y100. Along the direction Y100, the member 103 drives the valve 102 via the shoulder 109 when the shoulder 109 and the valve 101 are thus in contact with each other parallel to the direction Y100.

[0111] Preferably, the overtravel spring 104 tends to elastically move the valves 101 and 102 apart parallel to each other in the actuation direction Y100, bearing antagonistically on said valves 101 and 102. In practice, the spring 104 can be a helical compression spring surrounding the member 103, in particular the rod 110, coaxially with the axis Y30. The spring 104 ensures that, regardless of the position of the actuating member 103, the valve 101 bears in the direction Y100 either against the shoulder 108 or against the neck 33, and the valve 102 bears in the opposite direction to Y100, either against the shoulder 109 or against the necks 34 and 38.

[0112] As shown in [Fig.4], when the actuating member 103 is in the main position, the shoulder 108 of the actuating member 103 bears against the valve 101 in the opposite direction to the actuation direction Y100, thus keeping the valve 101 in the release position. In the main position of the actuating member 103, the shoulder 109 is distant from the valve 102 in the opposite direction to Y100, thus allowing the valve 102 to reach the bearing position against the collars 34 and 38. Preferably, in the main position, the actuating member 103 maintains the valve 101 in the release position against the action of the overtravel spring 104 and allows the valve 102 to reach the bearing position under the action of the overtravel spring 104. In the main position of the actuating member 103, the valves 101 and 102 are therefore positioned in the manner intended to obtain the main configuration, as defined above.

[0113] As shown in [Fig. 5], when the actuating member 103 is in the transient position, the shoulder 108 is distant from the valve 101 in the direction The actuation element Y100, possibly at a very small distance as shown in [Fig. 5], allows the valve 101 to reach the bearing position against the neck 33. When the actuating member 103 is in the transient position, the shoulder 109 is positioned away from the valve 102 in the opposite direction to the actuation direction, possibly at a very small distance as shown in [Fig. 5], to allow the valve 102 to reach the bearing position against the necks 34 and 38. Preferably, the valves 101 and 102 are brought into the bearing position against the neck 33 and against the necks 34 and 38, respectively, by the action of the spring 104. In the transient position of the actuating member 103, the valves 101 and 102 are therefore positioned in the manner intended to obtain the transient configuration, as defined above.

[0114] As shown in [Fig.6], when the actuating member 103 is in the maintenance position, the shoulder 108 of the actuating member 103 is away from the valve 101 in the direction Y100 to allow the valve 101 to reach the bearing position against the neck 33. In the maintenance position, the shoulder 109 of the member 103 bears against the valve 102 in the actuation direction Y100, thus maintaining the valve 102 in the release position. Preferably, in the maintenance position, the actuating member 103 allows the valve 101 to reach the support position under the action of the overtravel spring 104 and maintains the valve 102 in the release position against the action of the overtravel spring 104. In the maintenance position of the actuating member 103, the valves 101 and 102 are therefore positioned in the way intended to obtain the maintenance configuration, as defined above.

[0115] The actuating head 106 serves to enable a technician to actuate the mechanical selector 100, in particular the actuating member 103, from outside the body 21, and even from outside the main part 2 of the tap body 1, preferably with the aid of a tool. Preferably, the body 21 forms a coaxial through opening 37 with the Y30 axis, connecting the end 31 of the housing 30 on the outside of the body 21, inside the main part 2 of the valve body 1, outside the chamber 9. In particular, the opening 37 is arranged between the end 6 and the sealing gasket 78. This preferably implies that the Y30 axis is arranged between the end 6 and the sealing gasket 78. The actuation head 106 provides access to the outside of the body 21 via the opening 37, while being connected to the component 103 inside the housing 30.It is anticipated that the head 106 and / or the member 103 will seal the opening 37 in a watertight manner against the water present in the housing 30, in order to prevent water from leaking out of the body 21 via the opening 37. To this end, a seal is preferably interposed between, on the one hand, the head 106 and the member 103 and, on the other hand, the through opening 37.

[0116] Preferably, and as illustrated, the rod 110 of the actuating member 103 and the actuating head 106 are formed from a single, one-piece component, or are at least fixedly attached to each other at the end 31 of the housing 30, in or near the opening 37. In this example, the actuating member 103 and the actuating head 106 are fixedly rotatable relative to the body 21 about the axis Y30 and are fixedly translatable relative to the body 21 along the axis Y30, said rotation being subject to translation. Thus, rotating the actuating head 106 about the axis Y30 causes the actuating member 103 to translate from the main position to the maintenance position, passing through the transitional position. In other words, the assembly including the head 106 and the organ 103 is mobile relative to the body 21 according to a helical link along and around the axis Y30.

[0117] For this purpose, for example, as can be seen in [Fig. 2], the head 106 includes a radial finger 107, which is in sliding contact, in the opposite direction to the Y100 direction, on a helical surface 36 belonging to the body 21. For example, the helical surface 36 is arranged on the outside of the body 21, around the opening of the through-hole 37. Preferably, the spring 105 is arranged inside the housing 30, and pushes the member 103 in the opposite direction to the Y100 direction to keep the finger 107 in contact with the helical surface 36. For example, the spring 105 is an axially interposed compression spring between the end 31 of the housing 30 and the shoulder 108.

[0118] Alternatively, it could be provided that the head 106 is pivotable around the axis Y30 without being translatable along the axis Y30, that the member 103 is non-pivotable around the axis Y30 but translatable along the axis Y30, and that the pivoting of the head 106 causes the translation of the member 103, for example in that the head 106 and the member 103 are connected by a helical link.

[0119] Alternatively, a pull-tab system can be provided where the organ 103 and the head 106 are fixedly linked and translate without rotation.

[0120] Preferably, the head 106 forms a recess for a tool, which is oriented along the Y100 direction so that it can be accessed from outside the body 21 by the tool, if necessary through the opening 37, so that the tool actuates the head 106. Advantageously, a through hole 10 is provided, passing radially through the main part 2 of the body 1, and through the axis Y30 to align with the through opening 37. The tool can therefore reach the recess of the head 106 from outside the sanitary tap, through the hole 10 and possibly the through opening 37. It is therefore not necessary to dismantle the sanitary tap or access the underside of the sink to actuate the mechanical selector 100.

[0121] The base module 50 is described in more detail below, particularly with regard to the upper end 53 and the internal elements of the base body 51.

[0122] The base body 51 includes a mixed water outlet 56, referred to as the "base mixed water outlet," and a hot water outlet 57, referred to as the "base hot water outlet." Outlets 56 and 57 open at the upper end 53, facing end 7, i.e., upwards. Outlets 56 and 57 are shown in transparency, as dashed lines in [Fig. 4]. Outlet 57 is visible in [Fig. 7].

[0123] The cartridge body 81 includes a mixed water inlet 84, referred to as the "cartridge mixed water inlet," a hot water inlet 85, referred to as the "cartridge hot water inlet," and a mixed water outlet 89. The inlets 84 and 85 and the outlet 89 open at the lower end 82, facing the end 6, i.e., downwards. The inlets 84 and 85 are shown as dashed lines in [Fig. 4]. The inlet 85 and the outlet 89 are visible in [Fig. 7]. Preferably, no water inlets or outlets other than the inlets 84 and 85 and the outlet 89 are provided at the lower end 82.

[0124] The mixed water outlet 56 is connected to the mixed water inlet 84. To this end, the ends 53 and 82 are supported with the outlet 56 aligned with the inlet 84. A seal of this connection is advantageously ensured by a gasket surrounding the outlet of the outlet 56 on the end 53 or of the inlet 84 on the end 82, and interposed between the two ends. A flow of water exiting the body 51 through the outlet 56, which may be the flow A3 or the portion C26 of the flow C3 as explained below, is admitted into the body 81 via the inlet 84, without leaking into the main part 2 of the body 1 via the connection between the outlet 56 and the inlet 84.

[0125] The hot water outlet 57 is connected to the hot water inlet 85. To this end, the ends 53 and 82 are supported with the outlet 57 aligned with the inlet 85. A seal of this connection is advantageously ensured by a gasket surrounding the opening of the outlet 57 on the end 53 or of the inlet 85 on the end 82, and interposed between the two ends. A flow of water exiting the body 51 through the outlet 57 is admitted into the body 81 via the inlet 85, without leaking into the main part 2 of the body 1 via the connection between the outlet 57 and the inlet 85. As explained below, this flow of water is either the hot water flow C3 or the combination of parts C27 and C28 of the hot water flow C3.

[0126] The mixed water outlet 89 opens into an outlet passage 11, which is a volume belonging to chamber 9, delimited between the ends 82 and 52 along axis Z2. The mixed water outlet 89 thus supplies chamber 9, via the outlet passage 11, with the mixed water flow M3 formed in the cartridge body 81 from the water flows A3 and / or C3 that have been admitted into it. To open into chamber 9 and particularly in passage 11, exit 89 is arranged between fittings 78 and 79 along axis Z2.

[0127] The base body 51 includes the base housing 60, which extends along a housing axis Y60 between the ends 52 and 53. The base housing 60 comprises a first end 61 and a second end 62 that are opposite each other. The base housing 60 is traversed from the first end 61 to the second end 62 by the transverse axis Y60, which is here an axis perpendicular to the axis Z2 and offset from the axis Z2. Preferably, the base housing 60 has a shape of revolution centered on the axis Y60.

[0128] As shown in [Fig.7], the hot water inlet of the base 55 opens into the housing of the base 60 at the first end 61. The opening of the hot water inlet of the base 55 into the housing 60 is advantageously coaxial with the axis Y60.

[0129] Between the upper end 53 and the axis Y60, the base housing 60 opens into the hot water outlet 57, at an intermediate part of the housing 60 between the ends 61 and 62, near the end 61.

[0130] The base body 61 advantageously includes a collar 63, arranged between the ends 52 and 53, at the end 61 of the housing 60. The collar 63 is, for example, formed by an internal shoulder coaxial with the Y60 axis. The collar 63 can be formed directly by the wall of the body 51 delimiting the housing 60 or by an added part. Along the Y60 axis, the collar 63 is, for example, arranged at the opening of the inlet 55 into the base housing 60, or between the opening of the inlet 55 and the opening of the outlet 57 into the base housing 60. Thus, the hot water inlet of the base 55 leads to the hot water outlet of the base 57 via the housing 60, through the collar 63.

[0131] At the end 62, the base housing 60 opens outside the base body 51, at the outlet passage 11. Along the axis Y60, the outlet passage 11 is delimited between the base body 61 and the main part 2 of the valve body 1.

[0132] The base module 50 also includes a thermoactuator 70, attached to the base body 61. The thermoactuator 70 includes a temperature-sensitive part 71 fixedly attached to the body 51. The temperature-sensitive part 71 is partially housed in the housing 60, at the end 62, so as to close off the end 62. To this end, if necessary, a sealing gasket surrounding the temperature-sensitive part is interposed between the temperature-sensitive part 71 and the housing 60, at the end 62. The temperature-sensitive part 71 protrudes partially into the outlet passage 11 to be in contact with the mixed water flow M3. Consequently, the seals 78 and 79 are arranged on either side of the temperature-sensitive part 71, along the axis Z2. As shown in [Fig. 7], the temperature-sensitive part 71 advantageously protrudes into the outlet passage 11 by so that the outlet 89 of the cartridge 80 is vertical and very close to the thermosensitive part 71.

[0133] As shown in Figures 4 to 6, if the auxiliary inlet 59 is provided, the inlet 59 opens into the housing 60, advantageously along the thermoactuator 70, that is to say between, on the one hand, the end 62 and, on the other hand, the neck 63 and the outlet 57. Consequently, the inlet 59 leads to the outlet 57 via the housing 60 and the inlet 59 leads to the outlet 57 without passing through the neck 63. Preferably, the auxiliary hot water inlet 59 opens into the housing between the lower end 52 and the axis Y60.

[0134] The base module 50 also includes a shutter 72, arranged inside the base body 61, in particular inside the housing 60, between the heat-sensitive part 71 and the end 61. The shutter 72 is movable relative to the base body 61, preferably in translation along the Y60 axis. The mobility of the shutter 72 is from an open position, shown in [Fig. 7], to a safety position.

[0135] The thermo-actuator 70 is configured to actuate the shutter 72 from the open position to the safety position when the temperature of the temperature-sensitive part 71 exceeds a predetermined threshold, the temperature of the temperature of the temperature-sensitive part 71 reflecting the temperature of the mixed water flow M3 circulating in the outlet passage 11. For example, the thermo-actuator 70 is designed so that the predetermined threshold is approximately 55-60°C, corresponding to a threshold beyond which a user risks being scalded by the mixed water flow M3 exiting the sanitary tap. The thermo-actuator 70 advantageously includes a return spring 73 to return the shutter 72 from the safety position to the open position when the temperature falls below the predetermined threshold.

[0136] In the open position, the obturator 72 is recessed relative to the neck 63, so as not to obstruct the neck 63. Thus, the obturator 72 connects the hot water inlet of the base 55 to the hot water outlet of the base 57 via the neck 63 and the housing 60. When the obturator 72 is in the open position, the auxiliary hot water inlet 59 remains connected to the hot water outlet of the base 57 via the housing 60.

[0137] When the shutter 72 is in the open position, in both the main and transient configurations, the hot water flow C3 admitted to the hot water inlet 55 can flow to the hot water outlet 57. When the shutter 72 is in the open position, in the thermal disinfection configuration, the portion C27 of the hot water flow C3 admitted to the hot water inlet 55 can flow to the hot water outlet 57. In the main configuration, this allows the hot water flow C3 to be admitted into the cartridge 80 via the inlet 85, for normal operation of the tap when the temperature of the mixed flow M3 does not exceed the predetermined threshold, and therefore there is no risk of burns to the user.

[0138] When the shutter 72 is in the open position, the hot water inlet 55 is also connected to the auxiliary inlet 59, via the collar 63 and the housing 60. In both the main and transient configurations, the auxiliary outlet 28 is closed by the mechanical selector 100. Consequently, the hot water flow C3 admitted into the housing 60 is likely to flood the auxiliary inlet 59, but cannot, however, reach the housing 30 via the auxiliary inlet 59. In the thermal disinfection configuration, portion C28 of the flow C3 is admitted into the housing 60 from the auxiliary inlet 59, in parallel with portion C27 admitted to the hot water inlet 55. Portion C28 runs alongside the thermoactuator 70 and the shutter 72 in the housing 60. Both portions C27 and C28 of the flow are then discharged from the housing 60 via exit 57, after having been gathered in accommodation 60.These parts C27 and C28 together are then admitted into the cartridge body 81 via the inlet 85 to thermally disinfect the cartridge body 81. In all configurations, no part of the hot water flow C3 flows from the housing 60 to the outlet passage 11 through the end 62, since this is closed off by the thermoactuator 70, if necessary via the sealing gasket surrounding the thermosensitive part 71.

[0139] When the shutter 72 is in the safety position, the shutter 72 presses against the neck 63 to separate, or to significantly limit, the flow compared to the open position. When the shutter 72 is in the safety position, the flow C3 admitted at the inlet 55 in both the main and transient configurations is interrupted and therefore does not reach the outlet 57, or flows at a significantly reduced rate to the outlet 57 via the housing 60. In the main configuration, this prevents the hot water flow C3 from being admitted into the cartridge 80 to reduce the flow of hot water entering the formation of the mixed water flow M3. This lowers the temperature and / or the flow rate of the mixed water flow M3 exiting the sanitary tap, thus reducing the risk of scalding the user. When the shutter 72 is in the safety position, the auxiliary hot water inlet 59 remains connected to the base hot water outlet 57 via the housing 60.Preferably, the auxiliary hot water inlet 59 is connected to the base hot water outlet 57 via the housing 60 regardless of the position of the shutter 72.

[0140] When the shutter 72 is in the safety position and the selector 100 is in the thermal disinfection configuration, the portion C27 of the hot water flow C3 admitted at the inlet 55 is interrupted and therefore does not reach the outlet 57, or circulates at a severely limited flow rate to the outlet 57 via the housing 60. In this situation, the portion C28 of the hot water flow C3 reaches the outlet 57 by circulating in the housing 60. The portion C28 runs alongside the thermoactuator 70 and the rear of the shutter 72 in the housing 60. Therefore, regardless of the position of the shutter 72, housing 60 is disinfected by one and / or the other of parts C27 and C28 of the hot water flow C3. This hot water is conveyed to the cartridge body 81 via outlet 57 and inlet 85, to perform its thermal disinfection.

[0141] The base body 51 includes a conduit 65. The conduit 65 connects the mixed water inlet of the base 54 to the mixed water outlet of the base 56, bypassing the housing 60. Consequently, the inlet 54 leads to the outlet 56 via the conduit 65 without passing through the housing 60. Advantageously, it is not provided that the obturator can obturate the conduit 65, the inlet 54, or the outlet 56. Similarly, the inlets 55 and 59 lead to the outlet 57 via the housing 60 without passing through the conduit 65.

[0142] In the main configuration, the ambient water flow A3 supplied to outlet 26 flows entirely from inlet 54 to outlet 56, via conduit 65, regardless of the position of the shutter 72. The cartridge 80 is therefore supplied for normal operation. In the transient configuration, outlet 26 does not supply any water flow. In the thermal disinfection configuration, portion C26 of the hot water flow supplied to outlet 26 flows entirely from inlet 54 to outlet 56, thus disinfecting inlet 54, outlet 56, and conduit 65. The inlet 84 of the cartridge 80 is supplied with hot water via outlet 56 for disinfection of the body 81.

[0143] As shown schematically in [Fig.1], the cartridge 80 further preferably includes a ceramic disc mixer 90 and a control element 91.

[0144] The control member 91 is arranged at one end of the cartridge 80, which is opposite the lower end 82 along the axis Z2. Thus, the control member 91 can protrude from the upper end 7 of the valve body 1 to be operated by the user. In this case, the control member 91 includes a lever, which pivots about the body 81 around the axis Z2 and about an axis Y2 perpendicular to the axis Z2, fixed relative to the control member 91.

[0145] The ceramic disc mixer 90 is arranged inside the body 81, between the control member 91 and the lower end 82. The mixer 90 is controlled by the control member 91.

[0146] The cartridge mixed water inlet 84 and the hot water inlet 85 lead to the mixed water outlet 89 via the mixer 90. The mixer 90 mixes the water flows admitted to the inlets 84 and 85 to form the mixed water flow M3. The mixer 90 allows the flows 84 and 85 to be mixed in adjustable proportions using the control member 91, for example by pivoting the control member around the axis Z2 relative to the body 81, which makes it possible to obtain, in the main configuration, a desired temperature for the mixed water flow M3, which depends on the proportion of hot water and ambient water. mixed by the mixer 90. The mixer 90 also allows the flow rate of the mixed water flow M3 to be adjusted between zero and maximum flow, for example by pivoting the control member 91 around the axis Y2. Since the single control member 91 controls both the flow rate and the temperature of the mixed water flow M3, the cartridge 80 can be described as a "single-control cartridge".

[0147] Preferably, the control member 91 has a rotational stroke around the axis Y2, which is bounded between a so-called "full flow" orientation, corresponding to a case where the mixer 90 allows a maximum flow for the mixed flow M3, regardless of the proportion of the two incoming flows forming the mixed flow M3, and a so-called "zero flow" orientation, where the mixed water flow M3 is interrupted.

[0148] Preferably, the control member 91 has a rotational stroke around the axis Z2, which is bounded between a so-called "full hot" orientation, corresponding to a case where the mixer 90 ensures that the mixed flow M3, when it is not at zero flow rate, receives only the water flow from the hot water inlet 85, and a so-called "full cold" orientation, corresponding to a case where the mixer 90 ensures that the mixed flow M3, when it is not at zero flow rate, receives only the water flow from the mixed water inlet 84.

[0149] The disc mixer 90 comprises, for example, a lower ceramic disc 92, which is fixedly received in the body 81, and an upper ceramic disc 93, which is movable within the body 81, subject to the position of the control member 91 relative to the body 81. The discs 92 and 93 are, for example, coaxial or perpendicular to the axis Z2, and stacked along the axis Z2, with the disc 92 arranged between the disc 93 and the end 82, and with the disc 93 arranged between the disc 92 and the control member 91. The disc 93 rests on a sliding, sealed surface against the disc 92. The disc 92 comprises three through-channels, each connecting a lower face of the disc 92 to an upper face of the disc 92. The inlets 84 and 85 and the outlet 89 are respectively connected to the three through-channels via the lower face of the disc 92.The lower face of the disc 93, in sliding and watertight contact against the upper face of the disc 92, has a recessed pattern which connects the through-conduits of the disc 92 linked to the inlets 84 and 85 to the through-conduit linked to the outlet 89. These connections have a cross-section that varies according to the position of the disc 93, controlled by the control member 91. Thus, the disc 93, movable relative to the cartridge body 81 under the action of the control member 91 rotating around the axis Z2, regulates the value of the proportion between the flow rates of the two water streams A3 and / or C3 admitted to the inlets 84 and 85 in the formation of the outlet stream M3 by mixing the streams A3 and / or C3 in the mixer 90. It is also obtained that the disc 93, movable relative to the body. cartridge 81 under the action of the control member 91 rotating around the axis Y2, regulates the value of the flow rate of the mixed water flow M3.

[0150] Regardless of the embodiment of the cartridge 80, in thermal disinfection configuration, hot water from the flow C3 is admitted into both the inlets 84 and 85, which allows thermal disinfection of the body 81, the mixer 90 and the outlet 89. Then the mixed flow M3 is entirely made up of the flow C3.

[0151] Alternatively, another type of control unit and another type of disc mixer can be provided for the cartridge 80, allowing flow and temperature control of the mixed flow M3 from the water flows A3 and C3 supplied at the inlets 84 and 85.

[0152] Alternatively, it may be provided that the module 20 and the module 50 are not separable. In this case, the bodies 21 and 51 constitute, for example, a single body, either in one piece or formed by assembled parts, with a common part forming both the ends 23 and 52. In this case, it may be provided that the outlet 26 and the inlet 54 form two successive parts of the same conduit, that the outlet 27 and the inlet 55 form two parts of the same conduit, and that the outlet 28 and the inlet 59 form two parts of the same conduit.

[0153] Alternatively, the module 50 and the cartridge 80 may be provided for as inseparable. In this case, the bodies 51 and 81 constitute, for example, a single body, either in one piece or formed by assembled parts, with a common part forming both the ends 53 and 82. In this case, the outlet 56 and the inlet 84 may be provided for as two successive parts of the same conduit, and the outlet 57 and the inlet 85 may be two parts of the same conduit.

[0154] Alternatively, instead of a single-action cartridge, a sequential cartridge could be provided.
