    INSTRUMENT THERMOSTATIC REGULATION DEVICE AND MIXER TAP COMPRISING SUCH A THERMOSTATIC REGULATION DEVICE
    The present invention relates to an instrumented thermostatic regulation device, a thermostatic assembly comprising this thermostatic regulation device, as well as a thermostatic mixing valve equipped with such an assembly.
    The invention relates more generally to the field of sanitary installations for dispensing a fluid, in particular for dispensing water.
    Thermostatic mixer taps allow two fluid streams with different temperatures to be mixed, such as a hot fluid stream and a cold fluid stream. From this mixture results an outgoing fluid flow which has an intermediate temperature. The value of the intermediate temperature is adjustable by a user.
    To do this, the mixing valve has a thermostatic regulation device. This thermostatic regulation device comprises means for mixing the fluids and means for regulating the temperature of the mixed fluid.
    An example of a known thermostatic regulation device is described in patent FR-2821411-B1.
    Typically, these mixer taps can supply a sanitary installation with fluid, such as a shower, a washbasin, a sink or a bathtub.
    With the development of home automation applications, there is now a need for mixing valves which are capable of collecting usage data, for example the quantity of water consumed or the temperatures of the fluid involved, and of transmitting this data to a receiver outside the mixer tap, preferably by a wireless link. These new features should not, however, degrade the operation of the mixing valve, in particular with regard to its durability and user safety, nor complicate the integration of the mixing valve within existing installations.
    There is therefore a need for an instrumented thermostatic control device for a mixing valve capable of meeting the aforementioned needs.
    To this end, the invention relates to a thermostatic control device for a thermostatic mixer tap, the control device being adapted to produce a flow of mixed fluid from two flows of hot and cold fluid, characterized in that the device regulation is instrumented and includes for this purpose:
    a temperature sensor for measuring the temperature of the mixed fluid;
    a flow sensor for measuring the flow of the mixed fluid flow when the regulator is in a flow state;

    • a programmable electronic computer, • a communication interface provided with a radio antenna, • an electrical energy reserve, capable of electrically supplying the electronic computer and the communication interface;
    and in that the electronic circuit is adapted to collect the information measured by the sensors and to transmit this information to the outside by means of the communication interface.
    Thanks to the invention, the thermostatic control device is capable of collecting usage data and of transmitting this data to an external receiver. These collection and transmission functionalities are thus carried out in an integrated manner with the device, without the need to have recourse to a wired link and / or to physically connect additional equipment to the exterior of the mixing valve.
    According to advantageous but not compulsory aspects of the invention, such a thermostatic regulation device can incorporate one or more of the following characteristics, taken in isolation or according to any technically admissible combination:
    - The flow sensor is a hydraulic turbine adapted to electrically supply the energy reserve, such as an axial micro-turbine.
    - The communication interface is compatible with short-range wireless communication technology.
    - The regulating device also includes a temperature sensor for measuring the temperature of the cold fluid.
    - The energy reserve includes one or more super-capacitors.
    - The electronic circuit is at least partially housed inside an internal housing delimited by a part of a body of the regulating device, this housing being protected from fluid flows in a sealed manner.
    - The electronic calculator is programmed to transmit one or more of the usage data chosen from the group containing the following data:
    the evolution of the temperature of the mixed fluid over time, resulting from the measurement by the second sensor 24;
    issuing an alert if the temperature of the mixed fluid exceeds a predefined threshold;
    the evolution of the flow of mixed fluid from the measurement by the sensor 26; issuing an alert if the flow of mixed fluid exceeds a predefined threshold;
    the thermal power supplied by a device for producing hot fluid associated with it for heating cold water;
    the thermal energy corresponding to the thermal power supplied by the production device during a tap use cycle;
    an estimate of the financial cost associated with the production of thermal energy E for the duty cycle, date and time of the start and / or end of the duty cycle;
    duration of the cycle of use;
    average, minimum and maximum values of the temperature of mixed fluid during the cycle of use;
    average, minimum and maximum values of the flow of mixed fluid during the cycle of use;
    volume of water consumed during the cycle of use.
    The invention also relates to a thermostatic regulation assembly for a thermostatic mixing valve, this assembly comprising:
    a thermostatic control device for producing a flow of mixed fluid from two flows of hot and cold fluid;
    a device for regulating the flow of mixed fluid; characterized in that the thermostatic regulation device as described above.
    The invention also relates to a thermostatic mixing valve, comprising: a mixing valve body;
    a hot fluid inlet, a cold fluid inlet and a mixed fluid outlet;
    a thermostatic control device disposed inside the body and fluidly connected to the fluid inlets and the fluid outlet;
    the mixing valve being characterized in that the thermostatic regulation device is as described above.
    According to advantageous but not compulsory aspects of the invention, such a thermostatic mixing valve can have the following characteristic: the regulating device is integrated within an assembly including a main body and a device for regulating the flow of fluid, l assembly being arranged inside the valve body coaxially with this valve body, while the main body is separated from the internal walls of the valve body by a dry zone, and the device comprises an electrical connection which connects the electronic circuit to the sensors, this electrical connection being arranged in the dry zone.
    The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of an instrumented thermostatic regulation device, given solely by way of example and made with reference to the accompanying drawings in which:
    - Figure 1 is a schematic representation of a mixing valve fitted with a thermostatic regulation device instrumented according to embodiments of the invention;
    - Figure 2 is a block diagram of a thermostatic control device according to embodiments of the invention;
    - Figures 3 and 4 are sectional views of a portion of a thermostatic control device according to a first embodiment of the invention;
    - Figures 5 and 6 are sectional views of a portion of a thermostatic control device according to a second embodiment of the invention;
    - Figures 7 and 8 are sectional views of a portion of a thermostatic control device according to a third embodiment of the invention.
    Figure 1 shows an example of a thermostatic mixing valve 2 for the distribution of a fluid, such as water.
    The distributed fluid, called "mixed fluid" or "mixed fluid", is obtained by mixing a flow of hot fluid and a cold fluid.
    For example, the mixing valve 2 is intended to be mounted in a sanitary water distribution installation, such as a shower, a bathtub, a sink or a washbasin.
    In this embodiment, the mixing valve 2 comprises a body 4, a hot fluid inlet 6, a cold fluid inlet 8 and a mixed fluid outlet 10, a rotary knob 12 for adjusting the temperature and a rotary knob 14 for regulation of flow rate of mixed fluid leaving via outlet 10.
    For example, the body 4 has a hollow tubular shape extending along a longitudinal axis. The buttons 12 and 14 are mounted on opposite ends of the body 4, coaxially with the body 4, and are movable in rotation around this longitudinal axis.
    Optionally, the button 12 is provided with a locking member 13 which can be actuated manually and which makes it possible to selectively block the rotation of the button.
    12. The button 14 can also be provided with a similar locking member.
    The mixing valve 2 can be, alternately, in a state known as "flowing" in which the mixed fluid leaves via outlet 10, or in a state known as "non-debiting", in which no fluid flows through the outlet 10, even though the mixing valve 2 is supplied with fluid by the inputs 6 and 8.
    The mixing valve 2 comprises for this purpose a device for regulating the flow of fluid, controlled by the rotary button 14, which makes it possible to interrupt or, alternately, to authorize the flow of fluid in the mixing valve 2 to switch that - selectively between the debiting and non-debiting states. For example, the flow control device is a ceramic disc system.
    The mixing valve 2 also includes a thermostatic regulation device 16, housed inside the mixing valve 2, for example in the body 4.
    The device 16 makes it possible to mix the hot and cold fluid flows coming from the inputs 6 and 8 to obtain a mixed fluid flow, the temperature of which corresponds to a regulation temperature chosen by a user by means of the button 12.
    The device 16 is said to be “thermostatic” in the sense that it makes it possible to regulate the temperature of the mixed fluid to a constant and adjustable value, independently of the variations of pressures and respective temperatures of the incoming fluids hot and cold and of the flow of the outgoing fluid, this in a certain range of pressure and flow.
    FIG. 2 represents an example of the device 16, illustrated in a simplified manner.
    The device 16 includes a hot fluid inlet, a cold fluid inlet, and a mixed fluid outlet. These inputs and this output are respectively placed in fluid communication with the inputs 6, 8 and the output 10 when the device 16 is mounted inside the mixing valve 2.
    In what follows, to simplify the description, the fluid inputs of the mixing valve 2 are merged with those of the regulating device 16. The latter therefore do not bear a numerical reference and are not described in detail.
    We note “Fhot >> the flow of hot fluid coming from the entry 6,“ Fcold >> the flow of cold fluid coming from the entry 8 and “Fmix >> the flow of mixed fluid which results from the mixture of the flows Fhot and Fcold, the Fmix stream being intended to exit via exit 10.
    By extension, the distinction between debiting and non-debiting state also applies to device 16 in the rest of the description.
    According to embodiments, the device 16 comprises an elongated body extending along a longitudinal axis X16. For example, when the device 16 is mounted in the body 4, the longitudinal axis X16 is parallel, or even coincident, with the longitudinal axis of the body 4.
    For example, the body of the device 16 is made of plastic.
    According to embodiments, the device 16 is intended to be associated with the device for regulating the fluid flow rate previously defined to form a thermostatic assembly, or thermostatic assembly, intended to equip the mixing valve 2.
    The device 16 comprises an apparatus 20 for mixing the flows Fhot and Fcold and for regulating the temperature of the mixed fluid Fmix.
    The apparatus 20 is here mechanically coupled to the button 12 to allow the selection of a regulation temperature by a user.
    For example, this apparatus 20 is produced by thermostatic regulation components of the thermo-mechanical type, such as by means of a pre-assembled thermostatic cartridge.
    The role and operation of such thermostatic type thermostatic control components are known and in patents FR2774740, FR2869087 and FR2921709 filed in the name of the company VERNET SA.
    The device 16 is here said to be instrumented, in the sense that it further comprises electronic measurement and processing means for collecting and transmitting data relating to the use of the mixing valve 2.
    The device 16 thus comprises a first temperature sensor 22 for measuring the temperature T1 of the flow of cold fluid Fcold, a second temperature sensor 24 for measuring the temperature T2 of the mixed flow Fmix, a sensor 26 for measuring the flow rate Q of mixed flow Fmix, as well as an electronic processing circuit 28.
    The electronic circuit 28 includes a programmable electronic computer 30, a power supply circuit, also called a power stage 32, and a radio communication interface 34, as well as an electrical link 36.
    The power stage 32 includes an energy reserve 38. The computer 30 here comprises a logic calculation unit 40, a computer memory 42 and an electronic clock 44. The interface 34 comprises a radio antenna 46. The interface 34 allows in particular to ensure communication between the circuit 28 and a user terminal 48, or with a remote computer server 50.
    In what follows, the term "user device" is used to designate one or the other of the user terminal 48 and of the remote computer server 50.
    The circuit 28 is intended to collect the information measured by the sensors of the device 16 and to transmit this information to the exterior of the tap 2, for example to the devices 48 or 50, by means of the communications interface 34.
    The electrical link 36 electrically connects the circuit 28 with at least some of the sensors associated with the circuit 28, in particular with the sensors 24 and 26. It in particular makes it possible to convey energy and to transmit data.
    Thus, the sensors 22, 24 and 26 and the circuit 28 together form the aforementioned electronic measurement and processing means.
    It is understood in particular that the circuit 28 does not provide here the thermostatic regulation, this being ensured by the apparatus 20.
    The components of circuit 28 are described in more detail in the following with reference to FIG. 2.
    Preferably, the second temperature sensor 24 is a temperature sensor of ceramic technology with a negative temperature coefficient. This technology has the advantage of being reliable and economical.
    According to implementation variants, the first temperature sensor 22 can be omitted. However, when present, the temperature sensor 22 preferably uses technology similar to that of the temperature sensor 24.
    Alternatively, the temperature sensor 24 is a thermocouple.
    The second temperature sensor 24 is here located downstream of the apparatus 20, while the first temperature sensor 22 is located upstream of the apparatus 20 after the inlet 8. The terms “downstream” and “upstream” are defined with respect to the direction of flow of the fluid flows towards the outlet 10.
    The flow sensor 26 is adapted to measure the flow Q of the flow of mixed fluid Fmix at the outlet of the apparatus 20, before this flow leaves the system 16 and of the valve 2 via the outlet 10.
    Preferably, the sensor 26 is a turbine flow meter, arranged in the device 16 so as to be traversed by the flow of fluid Fmix when the valve 2 is in the debiting state.
    The use of a turbine flow meter is particularly advantageous, as it allows energy to be generated from the flow of Fmix fluid. In other words, the sensor 26 plays the role of both a flow sensor and an energy generator. The energy thus generated is used to supply the stage 32 and in particular to recharge the energy reserve 38.
    For example, the turbine 26 generates an electrical voltage, denoted “Vt”, when the flow of fluid Fmix flows through the turbine 26. This voltage is used both as a source of electrical power and as a signal giving information on the flow Q, as explained below.
    In the following description, when the sensor 26 is a turbine flow meter, it is designated by the term "turbine 26".
    In a particularly preferred manner, the turbine 26 is an axial micro-turbine.
    For example, such an axial micro-turbine comprises a hollow cylindrical body forming a stator and a rotor provided with one or more blades arranged inside the stator and capable of rotating around an axis of rotation corresponding to the longitudinal axis of the stator. The rotor is then rotated when the fluid Fmix flows through the microturbine. The micro-turbine also includes an electromagnetic circuit for generating an electrical output voltage when the rotor rotates. The axis of rotation of the rotor is here confused with the longitudinal axis X16.
    Preferably, the second temperature sensor 24 is integrated inside the turbine 26.
    An example of such a turbine 26 of the axial micro-turbine type is the axial micro-turbine manufactured by the company TOTO and described in JP 2007-274858 A.
    The use of an axial micro-turbine is advantageous because it offers a good compromise between the size of the turbine 26 and the quality of the electrical voltage signal supplied by the turbine, in particular to obtain a satisfactory linearity of the signal despite the variations in flow and hydraulic fluid pressure drop.
    By way of example, the measurement of the flow rate Q is carried out indirectly, by means of calculations, from characteristics of the measured electrical signal delivered by the turbine 26 (characteristics such as the frequency, and / or the amplitude, and / or instantaneous power) and / or characteristics of the load power received by the power stage 32, these calculations using predefined relationships, for example algebraic relationships or pre-recorded maps.
    For example, the calculation is carried out by means of the computer 30.
    As a variant, this processing is carried out by a dedicated logic or analog circuit integrated within the turbine 26, so that a signal representative of the flow rate Q is simply collected on an appropriate output of the turbine 26 independently of the voltage Vt.
    According to alternative embodiments of the invention, the turbine 26 is omitted. The flow sensor 26 is therefore not necessarily capable of generating energy. For example, the sensor 26 is an ultrasonic flow meter, or an electromagnetic flow meter, or a differential pressure sensor associated with a device of the “Pitot tube” type or of the “Venturi tube” type.
    Optionally, the device 16 may include an additional flow sensor, not illustrated, capable of measuring the flow Q and intended to assist the sensor 26. In fact, in practice, when a turbine is used as the sensor 26, it can happen that the turbine does not rotate when the flow rate Fmix is below a starting threshold, which depends in particular on the residual electromagnetic torque of the turbine. There are means to reduce this starting threshold, but they have the consequence of reducing the electric power supplied by the turbine.
    Thus, if a satisfactory compromise cannot be found, the additional flow sensor makes it possible to measure the flow Q during start-up phases during which the turbine 26 does not turn. Preferably, this additional sensor is then no longer used once the flow rate Fmix becomes sufficient to allow the turbine 26 to rotate. The circuit 28 is adapted accordingly to process the additional signal supplied by this flow sensor.
    For example, this additional flow sensor is produced using the flow sensor described in application FR 3019876 A1. Alternatively, one of the alternative flowmeter technologies described above can be used. The additional flow sensor is for example placed in series with the turbine 26 with respect to the flow of the fluid Fmix.
    The power stage 32 is now described with reference to FIG. 2. It is intended to supply the components of the electronic circuit 28 electrically and, in particular, to supply the computer 30 and the interface 34 electrically with a conditioned and stabilized electric voltage , such as a DC voltage, for example a DC voltage with an amplitude equal to 3.3 volts.
    To this end, the power stage 32 comprises at least one power converter for transforming the alternating voltages received from the turbine 26 into direct voltages able to be stored in the energy reserve 38 and / or to directly supply the other constituents of circuit 28.
    For example, the power stage 32 comprises a first AC / DC power converter of rectifier type, for transforming the electric voltage supplied by the turbine 26 into a DC voltage which supplies the energy reserve 38, and a second power converter. DC / DC power of the booster type, to transform the electrical voltage available across the energy reserve 38 into a stabilized DC voltage intended to supply the rest of the circuit 28.
    As a variant, the power converter (s) can be integrated into a dedicated power circuit associated with the turbine 26.
    In the embodiments where the sensor 26 is not a turbine and is not able to generate energy, then the power stage 32 and the power converter (s) are adapted accordingly.
    In this example, the energy reserve 38 comprises at least one supercapacitor 381, preferably several super-capacitors 381.
    The use of super-capacitors is advantageous since they have a small footprint and a longer service life compared to storage batteries. In practice, the energy reserve 38 undergoes a high number of charge and discharge cycles over time, these cycles being repeated with a high frequency of use, corresponding to the frequency of use of the mixing valve 2 For example, in a domestic sanitary installation, such a mixing valve 2 can be opened and then closed several tens of times, or even several hundred times in the space of a single day. The lifetime of the super-capacitors is less degraded by such a repetition of cycles than the duration of the known batteries.
    In addition, according to optional and advantageous embodiments, the reserve 38 also comprises a non-rechargeable battery 382, intended to be used to supply the essential functions of the circuit 28 when the super-capacitor (s) are discharged.
    Such a battery has the advantage of having a small footprint. Its non-rechargeable nature is not unacceptable, insofar as it is only intended to be used in an annex manner, only for troubleshooting when the supercapacitor (s) are discharged, and moreover to supply the circuit 28 when it performs only essential functions, these requiring less energy than the nominal functions of circuit 28.
    Thus, it is understood that, in certain modes of implementation, the reserve 38 is formed by the association of several energy storage means of different technology, which can be requested independently of each other depending on the circumstances, to supply all or part of the circuit 28.
    Advantageously, the power stage 32 includes an energy management device, not illustrated, intended to control the access and the operation of the reserve 38, in particular during the recharging phases of the reserve 38. The management device d energy is for example produced using a dedicated device, for example by programmable logic circuit or by any other equivalent means, preferably separate from the computer 30.
    As a variant, these functions are provided by the computer 30.
    Advantageously, the circuit 28 is switchable between a normal operating mode and a standby mode, in which certain functions of the circuit 28 are deactivated, in order to reduce the electrical consumption.
    This optimizes the electrical consumption of the circuit 28 and therefore preserves the autonomy of the energy reserve 38.
    The standby mode is activated when the mixer tap 2 is not in use, for example after a time spent in the non-debiting state greater than a predefined threshold. However, other management strategies are possible.
    The circuit 28 is thus adapted to be "woken up", that is to say toggled from its standby mode to its normal operating mode, automatically when the mixing valve 2 goes from the non-debiting state to the flow state.
    According to one example, the functions for managing the normal operating mode or in standby are provided by the energy management device described above.
    For example, this energy management device is suitable for detecting the debiting or non-debiting state from the flow information Q supplied by the turbine 26 or, more generally, supplied by the sensor 26.
    According to other alternative embodiments of the invention, the super-capacitors 381 are omitted. The energy reserve 38 instead comprises a rechargeable electric storage battery, for example of Lithium-ion technology, or of Nickel Metal Hydride technology. This battery is preferably used in conjunction with the turbine 26, so as to be recharged by the turbine 26. However, it can, as a variant, be associated with other recharging means.
    According to yet other variants, the energy reserve 38 is a non-rechargeable electric battery, such as an electric battery of Lithium-MnO 2 technology or of Lithium-SOCI 2 technology . In other words, the energy reserve 38 cannot then be recharged.
    According to another variant, the power stage 32 is adapted to be supplied electrically by a mains type electrical network. When the energy reserve 38 is at least partially rechargeable, then recharging is carried out using the energy supplied by this electrical network.
    An example of the electronic computer 30 is now described with reference to FIG. 2.
    The logic unit 40 is here a microprocessor or a programmable microcontroller.
    In this example, the memory 42 comprises a non-volatile memory, for example a memory module of the Flash type or any other equivalent technology. The memory 42 can also include a volatile working memory of RAM type for "Random Access Memory" in the English language.
    The memory 42 stores executable software instructions for ensuring the operation of the computer 30 and of the circuit 28 when these instructions are executed by the logic unit 40. For example, these executable instructions form a micro-software, or embedded software, of the computer 30 .
    In general, the computer 30 is programmed to collect the data coming from the sensors and to store them in memory, or even to reprocess them, before sending them to the device 48 or 50.
    According to one aspect, the computer 30 is preferably at least programmed to supply values of the following physical quantities, from the raw data measured using the sensors 22, 24 and 26: the temperature T2 of the mixed fluid, the flow rate Q of the mixed fluid, or even the temperature T1 of cold fluid, this for each instant t while the device 16 is in the debiting state.
    These values are for example instantaneous values or values averaged over a predefined time interval, for example over a cycle of use of the mixing valve 2.
    Within the meaning of the present description, by “use cycle”, we mean a succession of debiting and non-debiting states of valve 2, this succession for example implemented by a user to carry out a specific use.
    For example, a duty cycle begins when the valve 2 is actuated towards the debiting state after having remained in the non-debiting state for a duration greater than a predefined threshold, known as the "shutdown duration threshold". The usage cycle ends at the end of the last debiting state, that is to say the first debiting state to be followed by a non-debiting state of duration greater than or equal to the stop duration threshold.
    In other words, two consecutive uses of the valve 2 separated by a pause during which the valve is not used, that is to say during which it is in the non-debiting state, then these two uses are considered to be part of '' the same cycle of use if the duration of the break is short enough.
    As an illustrative example, a usage cycle may correspond to a shower taken by a user, this shower being able to be interrupted by occasional stops of limited duration.
    The calculation of the instants t of measurement and the counting of the durations are carried out here using the clock 44.
    According to another aspect, the computer 30 is advantageously programmed to allow the calculation in real time of the quantity of energy, denoted E, necessary to heat the hot fluid for a particular use, for example to allow the setting of a shower.
    For example, energy E is the energy required to heat a volume of cold water in order to have enough hot water for a user to take a shower.
    It is understood that, for the various embodiments described, the case of a shower is provided as a non-limiting example and that the computer 30 can also be programmed to implement such calculations for other types. applications other than a shower, and in particular for fluids other than water.
    This functionality is particularly advantageous when the tap 2 is intended to be part of a water distribution installation comprising a device for producing domestic hot water, such as a water heater or a hot water tank, controlled by a control system, for example home automation.
    Such a hot water production device operates by heating cold water which typically comes from the same source as that supplying the input 8. It is understood that this hot water production device is located upstream of the inlet 8 of tap 2.
    The information collected through the device 16 is thus used by the home automation control system to control the hot water production device, so as to optimize energy consumption.
    According to a first possibility, the computer 30 directly calculates the energy E in real time from the measured data and according to predefined formulas.
    According to another possibility, the computer 30 does not directly calculate the energy E, but rather intermediate quantities. These intermediate quantities are then used by an external calculation device, for example within the home automation control system, to calculate the energy E.
    For example, the quantities X and Y defined below are calculated automatically by the computer 30, for example in real time for each cycle of use:
    and
    X = y Tmt x Qi where "i" is an index identifying each measurement sample, "n" is a number equal to the total number of measurement samples for the duty cycle, "Tmi >> is the temperature value T2 for the instant corresponding to the measurement sample i, and “Qi >> is the value of the flow rate Q for the instant corresponding to the measurement sample i.
    The energy E is then calculated separately, from these quantities X and Y and from information on the cold water temperature value upstream of the hot water production device.
    For example, energy E is calculated using the following formula:
    E = Qx Cvx (X-Yx Tfe) where Cv is the volume thermal capacity of water.
    According to a variant, the computer 30 is advantageously programmed to estimate the temperature "Tfe" of cold water upstream of the device for producing hot water.
    In practice, this temperature Tfe can differ from the cold fluid temperature T1 measured by the first temperature sensor 22, especially when the valve 2 has been in the non-debiting state for a long time, hence the advantage of not being satisfied of the temperature measurement T1.
    Indeed, due to the heat exchanges with the environment, the cold water present in the tap 2 at the level of the sensor 22 may have a temperature substantially different from that of the cold water which arrives upstream of the device for producing hot water, especially at the start of a tap 2 use phase.
    According to a first example, the temperature Tfe for a use cycle is estimated to be equal to the minimum temperature value T1 during this use cycle.
    According to a second example, the temperature Tfe is estimated to be equal to the minimum temperature value T1 measured during all of the cycles of use of the valve 2 for a predetermined duration, this duration possibly ranging from one day to a few months.
    As a variant, instead of the estimate, a predefined temperature value Tfe can be taken instead, for example a parameter entered by a user, or a regional parameter predefined in the factory. Alternatively, if the home automation control system knows the temperature value Tfe of cold water entering the production device, for example because this is measured by means of a dedicated temperature sensor, then this value can be supplied to the computer 30, no estimate then being necessary.
    According to another aspect, the computer 30 is advantageously programmed to calculate summary data and statistics of use of the tap 2, in particular from the measured flow and temperature data as a function of time. These calculations are carried out according to predefined rules and according to parameters which can be modified by the user.
    By way of example, the computer 30 is adapted to store and / or calculate all or part of the following data relating to the real-time operation of the device 16, with a view to transmission via the interface 34:
    - the evolution of the temperature T2 over time, resulting from the measurement by the second sensor 24;
    - the issue of an alert if the temperature T2 exceeds a predefined threshold;
    - the evolution of the flow rate Q, resulting from the measurement by the sensor 26;
    - the issue of an alert if the flow Q exceeds a predefined threshold;
    - the thermal power P supplied by the hot water production device for heating cold water, this power P being calculated by the following formula:
    P = Q x Cv x (T2-Tfe), where Cv is the volume thermal capacity of water, this power can be instantaneous or averaged over a predefined period;
    - the thermal energy E corresponding to the thermal power P supplied by the production device during a cycle of use;
    - an estimate of the financial cost associated with the production of thermal energy E for the cycle of use, this estimate being calculated from the volume of water consumed, energy E consumed and a scale of unit cost previously defined and known to the computer 30.
    For example, the computer 30 is also suitable for storing and / or calculating all or part of the following summary data relating to a use cycle:
    - date and time of start and / or end of the use cycle;
    - duration of the use cycle;
    - average, minimum and maximum values of temperature T2 during the cycle of use;
    - average, minimum and maximum values of the flow rate Q during the cycle of use;
    - volume of water consumed during the use cycle.
    For example, so-called real-time data can be transmitted to the outside continuously during a duty cycle, but can also be stored before a subsequent transmission. In contrast, the summary data relating to a duty cycle can only be completely calculated and then transmitted once the duty cycle has been completed.
    It is therefore understood that, in general, the computer 30 can send the data to the outside in real time or in a delayed manner.
    When data is not transmitted in real time, it is stored in memory by the computer 30 for subsequent transmission. Preferably, they are erased after sending, so as to avoid saturating the memory 42.
    According to another aspect, the computer 30 is advantageously programmed to implement a “black box” type function, by recording, in a permanent memory, for example in memory 42, statistical data representative of the use of the tap. These data are intended to be used subsequently in the event of failure of the computer 30 and / or of the device 16, for example to analyze modes of failure of the device 16 in the event of damage, or even to confirm or deny allegations in the event of incident involving a user of valve 2, for example in the event of a burn due to too high a fluid temperature.
    In this example, the data recorded by the computer 30 includes:
    a unique identifier of the computer 30, comprising for example a serial number, a manufacturing batch number, a manufacturing date;
    an identifier of the version of the on-board software used by the computer 30;
    - maximum and minimum values of the measured temperatures T2 and, where appropriate, T1, for different measurement instants over time;
    - maximum and minimum values of the measured flow Q, for different instants of measurement over time
    - the number of cycles of use of the device 16.
    Preferably, the computer 30 is programmed to prevent alteration of this data recorded by an unauthorized user.
    The computer 30 can also send data relating to the electrical supply, such as statistics relating to the operation of the power stage 32 or a charge level of the energy reserve 38 and more particularly the charge level of the one or more super-capacitors and / or non-rechargeable battery, if applicable.
    According to another aspect, the computer 30 is advantageously programmed to implement a user access interface, which makes it possible to organize and regulate the data exchanges between the computer 30 and the terminal 48 or the server 50 when a connection is established by means of the interface 34. The user access interface thus allows an authorized user and / or a maintenance agent to access measured data and / or to change parameters, this by means of '' a website (in the case of the remote server 50) or a dedicated application (in the case of the terminal 48).
    The communication interface 34 is now described with reference to FIG. 2.
    The interface 34 is adapted to communicate, thanks to the antenna 46, according to one or more wireless communication protocols of the short-range wireless type. Preferably, the “Bluetooth Low Energy” protocol is used here, which makes it possible to transfer a large volume of data and which is compatible with a large number of mobile communication devices.
    In this way, the interface 34 can connect directly to a terminal 48 to exchange data as soon as this terminal 48 has a wireless communication interface of compatible technology and this terminal 48 is located at a distance from the device 16 less or equal to the maximum range of the technology used.
    For example, terminal 48 is a mobile communication device such as a mobile phone, or a tablet, or a laptop.
    As a variant, the terminal 48 is a specific terminal installed near the fluid distribution installation, for example a terminal installed in a shower cabin in which the tap 2 is installed. This terminal is then preferably provided with a display screen for displaying in real time data relating to the use of the tap 2, in particular chosen from those previously defined, such as the power P, the energy E or the financial cost.
    According to other variants, the terminal 48 is a module which can be integrated into a home automation installation, for example which can be integrated into the device for producing hot water described above or into the control system associated with it. This integration makes it easier to exchange data, for example to adapt operating parameters of the device 16, such as the temperature Tfe.
    In practice, the interface 34 can be connected simultaneously to several devices 48 and / or 50.
    The interface 34 also authorizes a connection of the computer 30 to the remote server 50, by means of an intermediate connection device, or concentrator, which plays the role of relay between the interface 34 and this remote server 50.
    For example, this is useful in the case of a remote server 50 which is not directly accessible via said short-range communications protocol, but which is accessible via one or more other networks d data exchange to which said intermediate connection device is connected. It can be an Internet network, or a machine-to-machine communication network, of the LoRaWAN type or of the "ultra-narrow band" type such as the SIGFOX ® protocol. The intermediate connection device is in turn provided with a wireless communication interface of technology compatible with the interface 34 so as to be able to communicate with the latter.
    In some cases, the terminal 48 can act as an intermediate connection device.
    According to examples, the server 50 is adapted to collect and analyze the data transmitted by the device 16, in order to analyze the consumption habits of the users. This analysis is for example carried out by a manufacturer of the tap or of the device 16, or by a service provider, or, in the case of use in collective housing, by a building manager.
    The purpose of this analysis is, for example, to provide a manufacturer or an operator with information allowing them to improve their products and services, or to provide users with information on their consumption in order to encourage them to optimize their water consumption.
    According to another example, this analysis makes it possible to prevent domestic accidents and / or to intervene in the event of such an accident. Thus, advantageously, when an alarm is generated by the computer 30, for example in the event of a temperature T2 too high, an alert signal is sent to the terminal 48 or to the server 50. In response, the latter automatically warns a personal assistance entity.
    In practice, in general, the exchange of data between the computer 30 and a user device 48 or 50 can be done either in a one-way communication mode (here from the computer 30 to a device 48 or 50), or in a two-way communication mode.
    Modes of implementing the physical integration of the circuit 28 within the device 16 are now described in a generic manner. Particular modes of implementation are illustrated in the examples of FIGS. 3 to 8.
    Preferably, the computer 30 also includes an electronic card 45 including a PCB-type substrate on which are mounted the components of the computer 30, such as the computer 40, the memory 42 and the clock 44, or even also components of the stage of power 32, and in particular the component or components forming the energy reserve 38.
    For example, the circuit 28 is integrated into the body of the device 16. In particular, the circuit 28 is advantageously arranged inside a housing formed at the level of a support for the rotary button 12.
    For example, the substrate used in the electronic card 45 has a disc shape provided with a central orifice. As an illustrative example, the diameter of the disc-shaped substrate is between 3cm and 5cm. The diameter of the central hole is between 1cm and 2cm.
    According to embodiments, the device 16 has a cylindrical shape with a longitudinal axis X16. In a mounted configuration, the card 45 is arranged perpendicular to this longitudinal axis X16. The central recess allows the passage of components of the device 16. For example, the card 45 is mounted coaxially around the longitudinal axis X16 with a coupling portion that can move in rotation and associated with the rotary button 12, this portion being able to pass through the central opening.
    The link 36 is preferably a wired link. It may include cables or a rigid preformed tab in which are provided conductors.
    For example, the link 36 has four conductors. Two of these conductors connect the turbine 26 to the electronic circuit 28, for example one for the electrical ground and one for the electrical phase, to deliver an electric current which feeds the power stage 32 and from which is extracted information on the flow rate Q. Two other of these conductors connect the sensor 22 to the circuit 28, for example to perform a resistance measurement at the terminals of the sensor 22 when the sensor 22 is a probe with a negative temperature coefficient. Alternatively, the link 36 includes a wired field bus, for example of the LIN type for "Local Interconnect Network".
    The link 36 is inserted into orifices made in the body of the device 16. Alternatively, it is overmolded during the manufacture of the device 16.
    According to variants, the sensor 22 is connected directly to the card 45. Thus, the sensor 22 is connected to the computer 30 independently of the link 36.
    The dimensions of the antenna 46 are adapted according to the technology used to implement the communications with the devices 48 and 50.
    For example, we use a half-wave dipole antenna or a quarter-wave antenna. For Bluetooth Low Energy technology operating at a frequency of 2.4 GHz, the antenna length is equal to 62.5mm or 31.25mm.
    The arrangement of the antenna 46 in the device 16 is chosen so as to avoid that the radio waves are blocked by metal forming part of the tap 2, which would prevent establishing communication with a device 48, 50 located at the outside valve 2.
    Preferably, the antenna 46 is mounted on the card 45. As a variant, however, it can be mounted outside the device 16. Such a variant may prove to be necessary when the device 16 is intended to be used in a tap 2 whose body 4 and / or buttons 12 and 14 are coated with a decorative metal such as chromium or gold.
    Figures 3 and 4 show a thermostatic regulation device 16 ’according to a first particular embodiment of the invention.
    The elements of thermostatic regulation device 16 ’which are analogous to the embodiment of the thermostatic regulation device 16 described above have the same references and are not described in detail, insofar as the above description can be transposed to them.
    More specifically, Figures 3 and 4 correspond to views in longitudinal section of the device 16 'according to different cutting planes.
    The body of the device 16 ′ here bears the reference 60. It comprises a first sleeve 62 and a second sleeve 64 between which the apparatus 20 for mixing and thermostatic regulation is disposed. The sleeves 62, 64 and the apparatus 20 are arranged coaxially with respect to the axis X16 and are connected to each other mechanically
    For example, the sleeves 62 and 64 are made of plastic.
    The apparatus 20 is here in the form of a preassembled cartridge provided with a housing inside which are arranged the internal components which ensure the thermostatic regulation. The apparatus 20 is here produced by means of a known thermostatic cartridge and described in patent FR2869087 in the name of the company VERNET SA.
    The turbine 26 is integral with the second sleeve 64. The sleeve 64 also incorporates the second temperature sensor 24 and, optionally, the first temperature sensor 22.
    The first sleeve 62 has an end portion 63 which delimits an internal housing V12. In other words, the V12 housing is delimited by a part of the body of the regulating device. The V12 housing is protected from Fmix, Fcold, Fhot fluid flows in a sealed manner. Circuit 28 is housed inside this housing V12. For example, the card 45 is mounted on the bottom of the housing V12.
    The link 36 is formed inside the sleeves 62 and 64. As indicated above, the link 36 can either be inserted in a housing prepared for this purpose during the construction of the sleeves 62 and 64, or be integrated inside sleeves 62 and 64 by overmolding during the construction of the sleeves 62 and 64.
    Preferably, a seal 66, for example an O-ring made of elastomeric material, is disposed at the junction between the end portion 63 and the rest of the sleeve 62, so as to seal against water. .
    Similarly, sealing elements, not shown, are provided at the junction of the sleeves 62 and 64 to prevent the fluid from coming into contact with the connection 36.
    The end portion 63 serves as a support for mounting the rotary button 12. However, the end portion 63 does not rotate with the button 12 and remains integral without degree of freedom with the rest of the body 62.
    However, the end portion 63 is crossed by a coupling portion which connects the rotary button 12 with a rotary device control member 20, so as to ensure mechanical coupling between the rotary button 12 and the device 20. The central orifice of the card 45 is crossed by this coupling portion.
    Apart from these construction differences, everything that has been described above with reference to the operation of the circuit 28 and of the sensors 22, 24 and 26 can be transposed to this embodiment.
    Figures 5 and 6 show a 16 ”thermostatic control device according to a second particular embodiment of the invention.
    The elements of the 16 ”thermostatic control device which are analogous to one of the previously described embodiments of the thermostatic control device bear the same references and are not described in detail, insofar as the above description can be be transposed.
    More specifically, Figures 5 and 6 correspond to views in longitudinal section of the device 16 ”according to different cutting planes.
    The body of the device 16 ”here bears the reference 70. The body 70 includes a first sleeve 72 and a second sleeve 74. The sleeves 72 and 74 are integral with each other and are arranged coaxially with respect to the axis X16.
    Similarly, sealing elements, not shown, are provided at the junction between the sleeves 72 and 74 to prevent fluid from coming into contact with the connection 36.
    The second sleeve 74 incorporates the turbine 26 and the second temperature sensor 24. The sleeve 74 is said to be an instrumented sleeve.
    Similarly to the sleeve 62 of the device 16 ’previously described, the sleeve 72 defines an internal housing V12 inside which the circuit 28 is housed. Here again, in the example illustrated, the central orifice of the card 45 is crossed by the coupling portion previously defined. Other arrangements are possible, however.
    In addition, the sleeve 72 defines an internal volume V20 intended to receive the apparatus 20.
    The internal constituents forming the apparatus 20 and which ensure the thermostatic regulation and the mixing of fluids are here distributed directly inside the volume V20. In other words, unlike the case of the device 16 ’previously described, the apparatus 20 is not here in the form of a preassembled cartridge.
    The role and operation of these constituents are well known and are not described in more detail below. They are for example described in patent FR2869087 in the name of the company VERNET SA.
    For example, the sensor 22 is housed in the sleeve 72.
    Apart from these construction differences, everything that has been described above with reference to the operation of the circuit 28 and of the sensors 22, 24 and 26 can be transposed to this embodiment.
    According to another embodiment, not illustrated, it is the second sleeve 74 which defines the volume V20 and which accommodates the components of the apparatus 20. The dimensions of the sleeves 72 and 74 are adapted accordingly. In particular, the second sleeve 74 is here longer than the first sleeve 72.
    Figures 7 and 8 show a 16 ’” thermostatic control device according to a third particular embodiment of the invention.
    The elements of the 16 '”thermostatic control device which are analogous to one of the previously described embodiments of the thermostatic control device bear the same references and are not described in detail, insofar as the above description can be transposed to them.
    More specifically, FIGS. 7 and 8 correspond to views in longitudinal section of the device 16 '”according to different cutting planes, the device 16'” being integrated within a thermostatic assembly itself integrated in a body 4 of mixing valve 2.
    In this example, the device 16 '”is directly integrated within an assembly including a main body 80 and also including a device for regulating the flow of fluid, which here bears the reference 90. The body 80 has here a shape essentially cylindrical extending along the X16 axis. For example, the body 80 is made of plastic.
    In the example illustrated, the device 90 is disposed at one end of the body 80 and is coupled with the button 14, while the device 16 '”is disposed at an opposite end of the body 80 and is coupled with the button 12. More specifically, the control member of the apparatus 20 is coupled to the button 12 via a coupling portion.
    The body 80 is separated from the internal walls of the body 4 by a dry area 82, that is to say an area through which no fluid can pass under normal operating conditions of the valve 2. For example, the area 82 is filled with air.
    For example, one or other of the inputs 6 and 8 of the valve 2 is arranged opposite a corresponding fluid inlet of the device 16 '”, for direct fluid connection, while the other inlet of tap fluid 2 (in this case, the inlet 6 of hot fluid) is fluidly connected to the corresponding inlet of the device 16 '”via a supply channel 84 formed in the body 80 .
    Likewise, the mixed fluid outlet of the 16 "device is fluidly connected to the outlet 10 via an outlet channel 86 formed in the body 80.
    In this way, the various fluid flows can circulate inside the valve 2, between the inlets 6, 8 and the outlet 10 and the device 16 "without entering the zone 82.
    The turbine 26 is formed inside the body 80. The outlet of the turbine 26 opens into a flow zone 88 formed in the body 80, for example at the center of this body 80. This zone 88 brings the mixed fluid Fmix towards the device 90. On leaving the device 90, the fraction of mixed fluid Fmix which is authorized by the device 90 to exit then circulates in the channel 86. In other words, the channel 86 opens at the outlet of the device 90.
    The link 36 is advantageously provided in the zone 82. In this way, the link 36 cannot come into contact with the fluids. In other words, the sealing and the protection of the link 36 are intrinsically ensured.
    In this example, the fluid inlets 6 and 8 are each provided with a non-return valve 92 and 94 respectively. The reference 96 designates a spacer separating the hot and cold fluid inlets at the level of the apparatus 20. In this embodiment, the apparatus 20 can be produced either in the form of a cartridge similar to that previously defined, or by directly incorporating the internal regulating constituents within the body 80.
    Apart from these construction differences, everything that has been described above with reference to the operation of the circuit 28 and of the sensors 22, 24 and 26 can be transposed to this embodiment.
    This third embodiment can be implemented independently of the previous embodiments. In particular, this third embodiment can be implemented with a thermostatic regulation device which is not instrumented, that is to say a thermostatic regulation device similar to the device 16 but in which the circuit 28 and the sensors 22, 24, 26 and the link 36 are omitted.
    Thus, the embodiments of the invention make it possible to obtain a particularly advantageous instrumented thermostatic regulation device. Because the circuit 28 is integrated into the device 16, it is not necessary to modify the size of the valve 2, which facilitates its integration into an existing sanitary installation. The presence of circuit 28 is transparent to the user of the valve 2. In particular, it does not alter the thermostatic regulation. Data exchange is carried out only by wireless means, which avoids having to connect wired links at the tap, as this would pose problems of integration and user security. The tightness formed at the level of the circuit 28 and of the link 36 limits the risk of damage to the electronics by the fluid circulating in the device 16 and 5 also reduces the risk of electrocution of the users of the valve 2.
    The embodiments and variants envisaged above can be combined with one another to generate new embodiments.
