Description

[0001] TITLE: Diverter module, internal assembly and associated sanitary valve

[0002] The present invention relates to a diverter module for a sanitary tap, an internal assembly comprising such a diverter module, and a sanitary tap comprising such an internal assembly.

[0003] FR3050512A1 describes a mixing unit for a mixer tap. This 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 mixing the two supply flows to form the supply flow, the mixing means being contained within the mixing chamber, and an additional housing extending from the mixing chamber. The mixing unit includes 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 an excessively hot mixed water supply.

[0004] For certain plumbing systems, particularly in healthcare facilities such as hospitals, it may be necessary to include a function to disinfect the mixing unit inside the faucet. One solution is to circulate very hot water through the mixing unit, including any additional anti-scalding housing, to achieve thermal disinfection. However, several constraints apply, notably that in some countries, such as France, regulations prohibit the installation of check valves in faucets and domestic water systems, and forbid the installation of a pressurized mixing chamber upstream of the faucet's ceramic disc aerator, primarily for hygiene reasons.Furthermore, to perform this thermal disinfection, it is not always possible, and in any case impractical, to install a device that would be placed under the sink or the sanitary fixture with the faucet. Finally, it is desirable to be able to easily modify existing installations to readily add the thermal disinfection function.

[0005] Therefore, one of the aims of the invention is to provide, in a manner that can be integrated into a sanitary tap possibly having an anti-scalding function, a solution for implementing a thermal disinfection function that is easy to use, without resorting to check valves or a mixing chamber upstream of the mixer already provided in the tap. To this end, the invention relates to a diverter module for a sanitary tap, the diverter module comprising: a diverter body, comprising:

[0006] • a lower end, which is traversed by a main axis, and

[0007] • an ambient water inlet for the diverter, formed at the lower end of the diverter body and configured to be fluidly connected to an ambient water line,

[0008] • 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,

[0009] • an upper end, which is traversed by the main axis and which is opposite the lower end of the derivative body,

[0010] • a mixed diverter water outlet, formed at the upper end of the diverter body, and

[0011] • a hot water outlet from the diverter, formed at the upper end of the diverter body; and a mechanical selector, arranged inside the diverter body between the upper and lower ends of the diverter body and capable of moving between:

[0012] • a main configuration, where:

[0013] 0 The mechanical selector connects the ambient water inlet of the diverter to the mixed water outlet of the diverter, so that a flow of ambient water admitted into the diverter body at the ambient water inlet of the diverter can flow to the mixed water outlet of the diverter.

[0014] 0 The mechanical selector separates the ambient water inlet of the diverter and the hot water outlet of the diverter from each other, so that the ambient water flow thus admitted does not reach the hot water outlet of the diverter.

[0015] 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

[0016] The mechanical selector separates the diverter's hot water inlet and mixed water outlet from each other, so that the hot water flow thus admitted does not reach the diverter's mixed water outlet; and

[0017] • a thermal disinfection configuration, where: 0 the mechanical selector separates the ambient water inlet of the diverter from the mixed water outlet of the diverter and the hot water outlet of the diverter, so that the flow of ambient water to the ambient water inlet of the diverter is interrupted,

[0018] 0 The mechanical selector connects the diverter's hot water inlet to the diverter's mixed water outlet so that a first portion of the admitted hot water flow can reach the diverter's mixed water outlet, and

[0019] 0 The diverter hot water inlet is connected to the diverter hot water outlet so that a second part of the hot water flow thus admitted can flow to the diverter hot water outlet.

[0020] A key idea of ​​the invention is to incorporate the thermal disinfection function in the form of a diverter module that can be attached to the sanitary tap, specifically to a base module of the tap, inside the tap itself. The diverter module can be provided as a separate module that can be modularly attached to the tap by assembly, or as an integrated module that is nevertheless easy to add to an existing internal tap assembly design.

[0021] Since the diverter module is fitted to the sanitary tap itself, it is easy to foresee that the mechanical selector can be operated from the sanitary tap itself, allowing easy access for a technician in charge of putting the mechanical selector into thermal disinfection configuration.

[0022] Furthermore, the diverter module can be installed upstream of any mixer, including ceramic disc mixers, and any shut-off valve capable of providing an anti-scalding function, which the sanitary tap might include. This is because the ambient and hot water lines are connected to the rest of the sanitary tap, specifically to the base module's inlets to which the diverter outlets are configured to connect, via the diverter module. However, the diverter module does not mix the ambient water flow admitted to the diverter's ambient water inlet and the hot water flow admitted to the diverter's hot water inlet, regardless of the current configuration of the mechanical selector, including the main configuration and the thermal disinfection configuration.

[0023] Indeed, in the main configuration, the ambient water flow admitted into the diverter module does not encounter the hot water flow, as the ambient water flow can only reach the diverter's mixed water outlet without reaching the diverter's hot water outlet, and the hot water flow can only reach the diverter's hot water outlet without reaching the diverter's mixed water outlet. In this configuration, the diverter's mixed water outlet functions as the ambient water outlet. Therefore, in the main configuration, the ambient water flow and the hot water flow are supplied to the rest of the sanitary faucet, for normal operation, as if these flows originated directly from the ambient and hot water pipes.

[0024] In thermal disinfection mode, ambient water flow is not admitted into the diverter module and therefore cannot come into contact with the hot water flow. The hot water flow, however, floods the diverter body, occupying most of the areas that were previously served by the ambient water flow in the main configuration, in order to thermally disinfect the diverter module itself. The hot water flow also reaches the diverter's mixed water outlet to thermally disinfect the rest of the faucet. In this case, the diverter's mixed water outlet becomes a hot water outlet for the purpose of thermal disinfection. In thermal disinfection mode, the hot water flow thus floods the channels, housings, and / or chambers of the sanitary faucet through which hot or ambient water normally circulated in the main configuration, thereby ensuring their thermal disinfection.

[0025] The diverter module also does not need to be fitted with a check valve, since, in thermal disinfection configuration, the mechanical selector disconnects the ambient water inlet from the diverter, ensuring that the hot water flow does not reach the ambient water inlet of the diverter.

[0026] 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:

[0027] - When switching from the main configuration to the thermal disinfection configuration and vice versa, the mechanical selector goes through a transitional configuration, where:

[0028] - the mechanical selector separates the ambient water inlet of the diverter from the mixed water outlet of the diverter and from the hot water outlet of the diverter, so that the flow of ambient water at the ambient water inlet of the diverter is interrupted;

[0029] - the diverter's hot water inlet is connected to the diverter's hot water outlet, so that the admitted flow of hot water can reach the diverter's hot water outlet; and

[0030] - The mechanical selector separates the diverter's hot water inlet and mixed water outlet from each other, so that the hot water thus admitted does not reach the diverter's mixed water outlet. - The diverter body includes a first neck, arranged between the lower and upper ends of the diverter body.

[0031] - The ambient water inlet of the diverter leads to the mixed water outlet of the diverter through the first neck.

[0032] - The mechanical selector includes a first valve which is movable relative to the diverter body between:

[0033] - a release position, adopted in the main configuration, where the first valve does not obstruct the first neck so that the ambient water inlet of the diverter is connected to the mixed water outlet of the diverter, and

[0034] - a support position, adopted in the thermal disinfection configuration and in the transient configuration, where the first valve closes the first neck so that the ambient water inlet from the diverter and the mixed water outlet from the diverter are separated.

[0035] - The diverting body includes a second neck, arranged between the lower end and the upper end of the diverting body.

[0036] - The diverter hot water inlet leads to the diverter hot water outlet upstream of the second collar so that the diverter hot water inlet is connected to the diverter hot water outlet regardless of the mechanical selector configuration.

[0037] - The hot water inlet from the diverter leads to the mixed water outlet from the diverter through the second neck.

[0038] - The mechanical selector includes a second valve which is movable relative to the diverter body between:

[0039] - a support position, adopted in the main configuration and in the transient configuration, where the second valve closes the second neck so that the diverter hot water inlet and the diverter mixed water outlet are separated, and

[0040] - a release position, adopted in the thermal disinfection configuration, where the second valve does not obstruct the second neck so that the diverter hot water inlet is connected to the diverter mixed water outlet.

[0041] - The first valve is movable relative to the diverter body along an actuation direction, from the release position to the support position, the actuation direction being transverse relative to the main axis.

[0042] - The second valve is movable relative to the diverter body along the actuation direction, from the supported position to the released position. - The mechanical selector includes an actuating element, which is arranged between the upper and lower ends of the diverter body, and which is movable relative to the diverter body along the actuation direction, from a main position, adopted in the main configuration, to a maintenance position, adopted in the thermal disinfection configuration.

[0043] - In the main position, the actuating member bears against the first valve in the opposite direction to the direction of actuation, thus maintaining the first valve in the release position, and allowing the second valve to reach the support position.

[0044] - In the maintenance position, the actuation device allows the first valve to reach the support position and bears against the second valve following the direction of actuation, thus maintaining the second valve in the release position.

[0045] - The mechanical selector includes an overtravel spring, which is arranged between the upper end and the lower end of the diverter body, which tends to elastically drive the first and second valves apart from each other parallel to the direction of actuation, by bearing on the first and second valves.

[0046] - In the main position, the actuating member holds the first valve in the released position against the action of the overtravel spring and allows the second valve to reach the resting position under the action of the overtravel spring

[0047] - In the maintenance position, the actuating member allows the first valve to reach the support position under the action of the overtravel spring and maintains the second valve in the release position against the action of the overtravel spring.

[0048] - In moving from the main position to the maintenance position, the actuating member passes through a transitional position, adopted in the transitional configuration, the actuating member allows the first valve to reach the support position under the action of the overtravel spring and the actuating member allows the second valve to reach the support position under the action of the overtravel spring.

[0049] - The derivation module includes an actuating head, which is arranged between the lower end and the upper end of the derivation body; is pivotable relative to the derivation body around a control axis parallel to the direction of actuation; and gives on the outside of the derivation body parallel to the direction of actuation, so as to be actuable from outside the derivation body, the mobility of the actuating member along the direction of actuation being subject to the pivoting of the actuating head.

[0050] - The diverter body includes an auxiliary hot water outlet, formed at the upper end of the diverter body. - In the main configuration, the mechanical selector separates the diverter ambient water inlet and the auxiliary hot water outlet from each other, so that the ambient water flow thus admitted does not reach the auxiliary hot water outlet, and the mechanical selector separates the diverter hot water inlet and the auxiliary hot water outlet thus admitted does not reach the auxiliary hot water outlet via the mechanical selector;

[0051] - In thermal disinfection configuration, the mechanical selector separates the diverter ambient water inlet and the auxiliary hot water outlet from each other, and the mechanical selector connects the diverter hot water inlet to the auxiliary hot water outlet so that a third part of the hot water flow thus admitted can flow to the auxiliary hot water outlet.

[0052] The invention also relates to an internal assembly comprising

[0053] - the differentiator module as defined above; and

[0054] - a base module, comprising a base body, which includes:

[0055] - a mixed water inlet at the base, formed at a lower end of the base body, the mixed water outlet of the diverter being fluidly connected to the mixed water inlet at the base,

[0056] - a hot water inlet at the base, formed at the lower end of the base body, the diverter hot water outlet being fluidly connected to the hot water inlet at the base,

[0059] Depending on additional advantageous features of the assembly according to the invention, taken individually or in all possible combinations:

[0060] - The base module includes a shutter, arranged inside the base body and movable relative to the base body between:

[0061] - an open position, where the shutter connects the base hot water inlet to the base hot water outlet, so that the flow of hot water admitted to the base hot water inlet can flow to the base hot water outlet, and

[0062] - A safety position, where the shutter separates the base hot water inlet and outlet, is positioned to severely limit the flow of hot water admitted to the base hot water inlet and flowing to the base hot water outlet. - The base mixed water inlet remains connected to the base mixed water outlet, whether the shutter is in the open or safety position.

[0063] - The base module includes a thermoactuator, attached to the base body, comprising a thermosensitive part arranged in an output 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.

[0064] - The base body includes a base housing, in which the thermoactuator is housed, an auxiliary hot water inlet, formed at the lower end of the base body and leading to the hot water outlet of the base via the base housing.

[0065] - The auxiliary hot water outlet is fluidly connected to the auxiliary hot water inlet.

[0066] - In the thermal disinfection configuration, the third part of the hot water flow is admitted into the base housing through the auxiliary hot water inlet so that it can flow to the hot water outlet of the base after having passed along the thermoactuator in the base housing.

[0067] - The base body includes an upper end, which is traversed by the main axis and which is opposite the lower end of the base body, the mixed water outlet of the base and the hot water outlet of the base being formed on the upper end of the base body.

[0068] - The internal assembly also includes a mixing cartridge, comprising:

[0069] • a cartridge body, comprising:

[0073] 0 a mixed water outlet, formed at the lower end of the cartridge body;

[0074] • a control element, movable relative to the cartridge body; and

[0075] • 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:

[0077] 0 is the value of the mixed water flow rate.

[0078] The invention also relates to a sanitary tap, comprising a tap body and the internal assembly as described above, received inside the tap body.

[0079] 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:

[0080] [Fig. 1] Figure 1 is a longitudinal cross-sectional view of a sanitary tap according to an embodiment of the invention.

[0081] [Fig. 2] Figure 2 is a perspective view of an internal assembly belonging to the sanitary tap of Figure 1, seen from a three-quarter front view.

[0082] [Fig. 3] Figure 3 is a rear view of the internal assembly of Figure 2.

[0083] [Fig. 4] Figure 4 is a partial longitudinal section view of the sanitary tap of the previous figures, following a radial section plane IV-IV shown in Figure 1, a diverter module belonging to the internal assembly being in a main configuration.

[0084] [Fig. 5] Figure 5 is a view similar to that of Figure 4, where the differentiator module is in a transient configuration.

[0085] [Fig. 6] Figure 6 is a view similar to those in Figures 4 and 5, where the derivatizer module is in a thermal disinfection configuration.

[0086] [Fig. 7] Figure 7 is a partial longitudinal section view of the sanitary tap from the previous figures, following another section plane radially passing through a thermoactuator belonging to the internal assembly.

[0087] 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.

[0088] 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 similar sanitary basin, or on a wall adjacent to said basin, the 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 within 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 Figure 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 heating system, for example a boiler or a hot water tank, to be supplied at a temperature between 40 and 85 °C.

[0089] Preferably, as shown in Figure 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 tap body 1 is fixedly mounted on the sanitary basin or the adjacent wall via 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 one end of the respective pipes 4 and 5 through the lower end 6, as shown in Figures 1 and 4 to 6.

[0090] 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 Figure 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.

[0091] 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 that 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. The diverter module 20 includes a diverter body 21, which has a lower end 22 and an upper end 23 opposite and traversed by the main axis Z2.

[0092] The base module 50 includes a base body 51, which includes a lower end 52 and an upper end 53 opposite and traversed by the main axis Z2.

[0093] The cartridge 80 includes a cartridge body 81, which includes a lower end 82 through which the main axis Z2 passes.

[0094] 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 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 axis Z2, with a single orientation relative to the other around axis Z2, ensuring the alignment of the water inlets and outlets of modules 20 and 50, defined below, for the fluidic connection of these inlets and outlets. The ends 23 and 52 thus constitute interfaces.

[0095] Preferably, the base module 50 bears against the mixing cartridge 80 along the main axis Z2, with its upper end 53 bearing against its lower end 82 along axis Z2. The base module 50 is thus interposed between the cartridge 80 and the diverter module 20 along 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.

[0096] Besides 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 crosses chamber 9 axially along the 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 shape, or portion of a ring, 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 perimeter of the internal assembly, around axis Z2, and over the entire internal perimeter of the main part 2 of the tap body 1. The outlet 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 chamber 9.

[0097] 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.

[0098] Preferably, the lower sealing gasket 78 is arranged at the height of the base body 51, or 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 with the inside of the part 2.

[0099] The derivative module 20 is described in more detail below.

[0100] 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 pipes 4 and 5 in order to connect to them.

[0101] 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 supply line 4. Preferably, the ambient water inlet 24 serves as a complementary connection element with the upper end of the supply line 4, ensuring a leak-proof fluid connection between the ambient water inlet 24 and the supply line 4. A seal is preferably provided at the interface between the supply line 4 and the inlet 24. In any case, the ambient water flow A3 supplied by the ambient water supply line 4 can be admitted into the body 21 via the ambient water inlet 24 without leaking into the main body 21 through the connection between the supply line 4 and the inlet 24. Preferably, a means for securing the supply line 4 to the diverter body 21 is provided by for example a stirrup or a pin.

[0102] The diverter body 21 includes a hot water inlet 25, referred to as the "diverter hot water inlet," which opens at its lower end 22. The downward-facing hot water inlet 25 connects to the hot water supply line 5. Preferably, the hot water inlet 25 serves as a complementary connection element with the upper end of the supply line 5, ensuring a leak-proof fluid connection between the hot water inlet 25 and the supply line 5. A seal is preferably provided at the interface between the supply line 5 and the inlet 25. In any case, the hot water flow C3 supplied by the hot water supply line 5 can be admitted into the body 21 via the hot water inlet 25 without leaking into the main body 21 through the connection between the supply line 5 and the inlet 25. Preferably, a means for securing the supply line 5 to the diverter body 21 is provided, for example, a stirrup or a pin.

[0103] Preferably, on end 22, inputs 24 and 25 are distributed diametrically on either side of axis Z2.

[0104] Preferably, no water inlets or outlets other than inlets 24 and 25 are provided at the lower end 22.

[0105] 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.

[0106] 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 preferably an auxiliary hot water outlet 28. Outlets 26, 27, and 28 terminate at the upper end 23, facing the end 7, i.e., upwards. Outlets 26 and 28 are visible in Figures 4 to 6, while outlet 27 is visible in Figure 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.

[0107] 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, preferably, 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 Figure 7. Preferably, no water inlets or outlets other than the inlets 54, 55, and 59 are provided at the lower end 52.

[0108] 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.

[0109] As shown in Figure 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 is advantageously ensured by a gasket surrounding the opening of the outlet 27 on end 23 or of the inlet 55 on 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 water flow is either the hot water flow C3 or a portion C27 of the hot water flow C3.

[0110] As shown in Figures 4 to 6, the hot water outlet 28, if present, 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 is advantageously ensured for this connection by a gasket surrounding the opening of the outlet 28 on end 23 or of the inlet 59 on 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 via the connection between the outlet 28 and the inlet 59. As explained below, this water flow is part C28 of the hot water flow C3.

[0111] Preferably, on end 23, outputs 26, 27, and 28 are arranged in a triangle. Inputs 54, 55, and 59 are arranged correspondingly on end 52.

[0112] 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 facing opposite directions. 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.

[0113] Along the Y30 axis, we also define a Y100 direction, called the "acting direction", which goes from end 32 to end 31.

[0114] 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 point within 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 point within housing 30 between outlet 26 and end 32.

[0115] The diverter body 21 advantageously includes a neck 33, arranged between the ends 22 and 23, within the diverter housing 30. The neck 33 is, for example, formed by an internal shoulder preferably coaxial with the Y30 axis. 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 Y30 axis, 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.

[0116] The derivat body 21 advantageously includes a neck 34, arranged between the ends 22 and 23, in the derivat 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 Y30 axis, the neck 34 is arranged between, on the one hand, the opening of the inlet 25 into the diverter housing 30 and, on the other hand, the openings of the outlets 26 and 28 into the diverter housing 30. In particular, along the Y30 axis, the neck 34 is formed between the opening of the inlet 25 and the opening of the outlet 28. Along the Y30 axis, the neck 34 is formed between the neck 33 and the end 32. In other words, the neck 33 is in the Y100 direction relative to the neck 34.Thus, the hot water inlet of diverter 25 leads to the mixed water outlet of diverter 26 and, if provided, to the auxiliary hot water outlet 28, via housing 30, through the collar 34.

[0117] The derivat body 21 advantageously includes 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.

[0118] Preferably, as best seen in Figure 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. Therefore, 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 occurring 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.

[0119] The derivatization module includes a mechanical selector 100, arranged inside the derivatization body 21 between the ends 22 and 23. In particular, the mechanical selector 100 extends at least partially into the housing 30.

[0120] At the command of a technician, the mechanical selector 100 is capable of switching between a main configuration, shown in Figure 4, and a thermal disinfection configuration, shown in Figure 6. The selector 100 preferentially passes through a transitional configuration, shown in Figure 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.

[0121] 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.

[0122] The valves 101 and 102 are designed to allow selector 100 to reach the main configuration, the thermal disinfection configuration and, if provided, the transitional configuration.

[0123] 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 Figure 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.

[0124] The valve 102 is arranged inside the housing 30, near the collars 34 and 38, preferably between collar 33 and collar 34. Preferably, the valve 102 is an annular piece, coaxial with the Y30 axis. The valve 102 is movable, for example, translationally movable along the Y100 direction, relative to the diverter body 21, from a rest 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 Figure 6. When the valve 102 is in the release position, it is at a distance from the necks 34 and 38 in the Y100 direction, so as not to close the necks 34 and 38. In its rest position, the valve 102 rests against the necks 34 and 38 in the opposite direction to Y100, so that the valve 102 closes the necks 34 and 38. Regardless of its In this position, the valve 102 does not close the neck 33.

[0125] As shown in Figure 4, when selector 100 is in the main configuration, valve 101 is in the release position. Therefore, the neck 33 is not closed, which means that the ambient water inlet of diverter 24 is connected to the mixed water outlet of diverter 26 through the neck 33, allowing the ambient water flow A3 to circulate from inlet 24 to outlet 26 via the neck 33.

[0126] Regardless of the position of valves 101 and 102, the hot water inlet of diverter 25 leads to the hot water outlet of diverter 27 via 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, whether selector 100 is in main, transient, or thermal disinfection configuration. In particular, this connection is established independently of the position of valves 101 and 102.

[0127] In the main configuration, the other valve 102 is in the supported position. Since valve 102 closes 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, because 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 therefore reach the outlets 26 and 28 and the inlet 24. No check valve is required.

[0128] In its main configuration, the valve 102, in its supported position, also closes the neck 38, preventing the housing 30 from connecting the inlet 24 and outlet 26 to the outlets 27 and 28 and 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.

[0129] 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.

[0130] In summary, in the main configuration shown in Figure 4, the mechanical selector 100 connects the ambient water inlet of diverter 24 to the mixed water outlet of 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 diverter 24 is permitted and guided to flow to the mixed water outlet of diverter 26 via the housing 30. In the main configuration, the mechanical selector 100 separates the ambient water inlet of diverter 24 and the hot water outlet of diverter 27 from each other, so that the ambient water flow A3 admitted through inlet 24 does not reach the hot water outlet of the diverter.

[0131] 27. In the main configuration, the diverter hot water inlet 25 is connected to the diverter hot water outlet 27 via the conduit 35, so that the hot water flow C3 admitted into the diverter body 21 at the diverter hot water inlet 25 flows to the diverter hot water outlet 27. In the main configuration, the mechanical selector 100 separates the diverter hot water inlet 25 and the diverter mixed water outlet 26 from each other, so that the hot water flow C3 admitted to the inlet 25 does not reach the diverter mixed water outlet 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.

[0132] 28.

[0133] 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, if provided, 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.

[0134] As shown in Figure 5, when selector 100 is in the transient configuration, if provided, valves 101 and 102 are both in the support position, thus closing the necks 33, 34 and 38.

[0135] With the neck 33 blocked, the inlet 24 is separated from the outlets 26, 27 and 28 and the inlet 25. The ambient water flow A3 at the inlet 24 is interrupted by the blocked neck 33 and therefore cannot reach the outlets 26, 27 and 28 and the inlet 25.

[0136] With neck 34 blocked, inlet 25 is separated from outlets 26 and 28 and from inlet 24. The hot water flow C3 at inlet 25 therefore cannot reach outlets 26 and 28 or inlet 24. However, the hot water flow C3 is not interrupted, since inlet 25 remains connected to outlet 27 via conduit 35. The hot water flow C3 admitted at inlet 25 is thus conducted entirely to outlet 27 via conduit 35. Since necks 33 and 38 are blocked, residual ambient water, initially admitted into body 21 via inlet 24 while the mechanical selector 100 was in its main configuration and which would have accumulated between the two necks 33 and 38, cannot reach inlet 25 or outlets 27 and 28.

[0137] 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.

[0138] The transitional 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 transitional configuration, the connection of inlet 25 to outlets 26 and 28 in the thermal disinfection configuration is ensured only after inlet 24 has been separated from outlet 26 during the transitional configuration. Similarly, in this transitional configuration, the connection of inlet 24 to outlet 26 in the main configuration is ensured only after outlets 26 and 28 have been separated from inlet 25 during the transitional configuration.

[0139] As shown in Figure 6, when selector 100 is in the thermal disinfection configuration, valve 101 is in the supported position and valve 102 is in the released position. In the thermal disinfection configuration, valve 101 in the supported position closes the neck 33 so that the ambient water inlet of diverter 24 is separated from outlets 26, 27, and 28, as well as from inlet 25. Indeed, inlet 24 can only lead to outlets 26, 27, and 28 and to inlet 25 via the neck 33, which is currently closed. The flow of ambient water A3 at 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, if provided, to the auxiliary hot water outlet 28.The hot water inlet 25 remains connected to the hot water outlet 27 via the conduit 35. As a result, the hot water flow C3 admitted to the inlet 25 is divided into portion C27, which can flow from the inlet 25 to the outlet 27 via the conduit 35; portion C28, which can flow from the inlet 25 to the outlet 28 via the neck 34; and portion C26, which can flow from the inlet 25 to the outlet 26, successively via the neck 34 and the neck 38. However, with the valve 101 in the closed position to block the neck 33, no portion of the flow C3 from the inlet 25 can reach the inlet 24. When switching from the main configuration to the thermal disinfection configuration, residual ambient water, coming initially from the inlet 24 and which would have accumulated in the chamber 30 downstream of the neck 33, is then expelled by the part C26 of the hot water flow C3 towards the outside of the body 21 via the 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.

[0140] 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 diverter 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. Selector 100 thus prevents the ambient water flow A3 from reaching outlets 26, 27, and 28 and 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 hot water outlet of diverter 27 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 inlet 25 to flow to the mixed water outlet of diverter 26. This allows a portion C27 of the hot water flow C3 to flow to the hot water outlet of diverter 27.This allows a portion C28 of the hot water flow C3 to flow to the auxiliary hot water outlet 28.

[0141] The thermal disinfection configuration is used to perform thermal disinfection of the sanitary tap, specifically 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.

[0142] The actuating member 103, the head 106, and the springs 104 and 105 are designed to allow the technician to actuate the valves 101 and 102, necessarily obtaining the configurations defined above. Preferably, the actuating member 103 is received, for the most part or entirely, in the housing 30, at least for the main configuration. Preferably, the actuation 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.

[0143] The actuation member 103 is movable in translation relative to the body 21, along the direction Y100, from a main position, shown in Figure 4, to a maintenance position, shown in Figure 6, passing through an intermediate position, shown in Figure 5. Preferably, the actuation member 103 is also movable in rotation about the axis Y30 relative to the body 21, as explained below.

[0144] 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 the shoulder 108. between shoulder 108 and valve 102. Valve 102 is arranged in the Y100 direction relative to the shoulder.

[0145] 109, between the shoulder 109 and the valve 101. Each valve 101 and 102 is optionally pivoting around the axis Y30 relative to the component 103, or may be non-pivoting around the axis Y30 relative to the component 103.

[0146] The valve 101 is movable relative to the component 103, in particular relative to the rod

[0147] 110, following the direction Y100, until it comes to rest against the nearest element between the shoulder 108 and the neck 33 following 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.

[0148] 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.

[0149] 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.

[0150] As shown in Figure 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.

[0151] As shown in Figure 5, when the actuating member 103 is in the transitional position, the shoulder 108 is positioned away from the valve 101 along the actuation direction Y 100, possibly at a very small distance as shown in Figure 5, to allow the valve 101 to reach the bearing position against the neck 33. When the actuating member 103 is in the transitional 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 Figure 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 actuation member 103, the valves 101 and 102 are therefore positioned in the manner intended to obtain the transient configuration, as defined above.

[0152] As shown in Figure 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.

[0153] The actuating head 106 is used so that a technician can 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 axis Y30, connecting the end 31 of the housing 30 to 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 axis Y30 is arranged between the end 6 and the sealing gasket 78. The actuation head 106 gives way 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.

[0154] 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 at least are 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.

[0155] For this purpose, for example, as can be seen in Figure 2, the head 106 includes a radial finger 107, which slides in the opposite direction to Y100 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 Y100 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.

[0156] 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.

[0157] Alternatively, a pull-tab system can be provided where the organ 103 and the head 106 are fixedly linked and translate without rotation.

[0158] 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.

[0159] The base module 50 is described in more detail below, particularly concerning the upper end 53 and the internal elements of the base body 51.

[0160] 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 Figure 4. Outlet 57 is visible in Figure 7.

[0161] 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, being turned towards the end 6, i.e. downwards. Inlets 84 and 85 are shown as dashed lines in Figure 4. Inlet 85 and outlet 89 are visible in Figure 7. Preferably, no water inlets or outlets other than inlets 84 and 85 and outlet 89 are provided at the lower end 82. The mixed water outlet 56 is connected to the mixed water inlet 84. To this end, the supports of ends 53 and 82 are made with outlet 56 aligned with inlet 84. A seal for this connection is advantageously ensured by a gasket surrounding the outlet of outlet 56 on end 53 or of inlet 84 on end 82, and interposed between the two ends.A water flow exiting body 51 through outlet 56, which can be flow A3 or portion C26 of flow C3 as explained below, is admitted into body 81 via inlet 84, without leaking into the main part 2 of body 1 via the connection between outlet 56 and inlet 84.

[0162] 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 water flow is either the hot water flow C3 or the combination of parts C27 and C28 of the hot water flow C3.

[0163] 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 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 specifically into passage 11, the outlet 89 is arranged between the seals 78 and 79 along axis Z2.

[0164] 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 in opposition. The base housing

[0165] 60 is traversed from the first end 61 to the second end 62 by the transverse axis Y60, which here is an axis perpendicular to the axis Z2 and offset with respect to the axis Z2. Preferably, the base housing 60 has a shape of revolution centered on the axis Y60.

[0166] As shown in Figure 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 Y60 axis.

[0167] Between the upper end 53 and the Y60 axis, the base housing 60 opens into the hot water outlet 57, at an intermediate part of the housing 60 between the ends

[0168] 61 and 62, near end 61. The base body 61 advantageously includes a collar 63, arranged between ends 52 and 53, at end 61 of housing 60. The collar 63 is, for example, formed by an internal shoulder coaxial with axis Y60. The collar 63 can be formed directly by the wall of body 51 delimiting housing 60 or by an added piece. Along axis Y60, the collar 63 is, for example, arranged at the opening of inlet 55 into base housing 60, or between the opening of inlet 55 and the opening of outlet 57 into base housing 60. Thus, the hot water inlet of base 55 leads to the hot water outlet of base 57 via housing 60, through the collar 63.

[0169] 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.

[0170] The base module 50 also includes a thermo-actuator 70, attached to the base body 61. The thermo-actuator 70 comprises a temperature-sensitive part 71 fixedly attached to the body 51. The temperature-sensitive part 71 is partially housed within the housing 60 at its end 62, so as to seal 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 its 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 Figure 7, the thermosensitive part 71 protrudes advantageously into the exit passage 11 so that the outlet 89 of the cartridge 80 is vertical and very close to the thermosensitive part 71.

[0171] 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 Y-axis 60.

[0172] The base module 50 also includes a shutter 72, arranged inside the base body 61, specifically 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 shutter 72 moves from an open position, shown in Figure 7, to a secure position.

[0173] 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, whereby the temperature of the temperature-sensitive part 71 reflects 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.

[0174] In the open position, the shutter 72 is recessed relative to the neck 63, so as not to obstruct the neck 63. Thus, the shutter 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 shutter 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.

[0175] When the shutter 72 is in the open position, in both the main and transient configurations, the hot water flow C3 admitted at the hot water inlet of the base 55 can flow to the hot water outlet of the base 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 at the hot water inlet of the base 55 can flow to the hot water outlet of the base 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 scalding for the user.

[0176] When the shutter 72 is in the open position, the hot water inlet 55 is also connected to the auxiliary inlet 59, if present, 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 may enter the auxiliary inlet 59, but cannot 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 thermo-actuator 70 and the shutter 72 within 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 by the thermoactuator 70, if necessary via the sealing gasket surrounding the thermosensitive part 71.

[0177] When the shutter 72 is in the safety position, it presses against the neck 63 to separate, or significantly restrict, the flow compared to the open position. When the shutter 72 is in the safety position, the flow C3 admitted to 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 entering the cartridge 80, thus reducing the hot water flow entering the formation of the mixed water flow M3. This lowers the temperature and / or flow rate of the mixed water flow M3 exiting the tap, thereby 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.

[0178] 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. Consequently, regardless of the position of the shutter 72, the housing 60 is disinfected by one or both portions 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.

[0179] 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 plug can block 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.

[0180] 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 supplies no 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.

[0181] As shown schematically in Figure 1, the cartridge 80 further preferably includes a ceramic disc mixer 90 and a control unit 91.

[0182] The control element 91 is arranged at one end of the cartridge 80, opposite the lower end 82 along axis Z2. Thus, the control element 91 can protrude from the upper end 7 of the valve body 1 to be operated by the user. In this case, the control element 91 includes a lever, which pivots about the body 81 around axis Z2 and about an axis Y2 perpendicular to axis Z2, fixed relative to the control element 91.

[0183] 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.

[0184] The mixed cartridge water inlet 84 and the hot water inlet 85 lead to the mixed water outlet 89 via the mixer 90. The mixer 90 has the function of mixing 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 proportions adjustable using the control element 91, for example by pivoting the control element 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 makes it possible to adjust the flow rate of the mixed water flow M3 between a zero flow rate and a maximum flow rate, for example by pivoting the control element 91 around the axis Y2.Since the single control unit 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".

[0185] Preferably, the control element 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.

[0186] Preferably, the control element 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.

[0187] 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 element 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 element 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 underside of disc 93, in sliding and watertight contact with the upper side of disc 92, has a recessed pattern that connects the through-conduits of disc 92, linked to inlets 84 and 85, to the through-conduit linked to outlet 89. These connections have a cross-section that varies according to the position of disc 93, controlled by the control element 91. Thus, disc 93, movable relative to the cartridge body 81 under the action of the control element 91 rotating about axis Z2, regulates the ratio between the flow rates of the two water streams A3 and / or C3 admitted to inlets 84 and 85 in the formation of the outlet stream M3 by mixing the A3 and / or C3 streams in the mixer 90. Disc 93, movable relative to the cartridge body 81 under the action of the control element 91 rotating about axis Y2, also regulates the value of the mixed water flow rate M3.

[0188] Regardless of the embodiment of the cartridge 80, in thermal disinfection configuration, hot water from the C3 flow 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 C3 flow.

[0189] 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.

[0190] Alternatively, modules 20 and 50 can be stipulated to be inseparable. In this case, bodies 21 and 51 constitute, for example, a single body, either in one piece or formed from assembled parts, with a common part forming both ends 23 and 52. In this case, outlet 26 and inlet 54 can be stipulated to form two successive parts of the same conduit, outlet 27 and inlet 55 to form two parts of the same conduit, and outlet 28 and inlet 59 to form two parts of the same conduit.

[0191] 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 from 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.

[0192] Alternatively, instead of a single-action cartridge, a sequential cartridge could be used.
