[0023] Throughout all the figures, the common elements are identified by identical numerical references. Description of the implementation methods

[0024] A shower system is presented according to one aspect of the invention with reference to figures 1 to 6.

[0025] System 1 as proposed comprises - a 10cm shower tray or shower base, - a 20mm hand shower and a 30mm overhead shower, - a 40 mixer tap, and - a 50 controller.

[0026] The shower tray 10 forms the base of the system. It is adapted to collect shower water and includes a water drainage pipe 12 adapted to be connected to a wastewater pipe.

[0027] The system also typically includes walls so as to form a shower cubicle 2.

[0028] The mixer 40 is connected to the hand shower 20 and the overhead shower 30 respectively via a first outlet 42 and a second outlet 43, and is adapted to supply water to the hand shower 20 and / or the overhead shower 30.

[0029] The mixer 40 conventionally comprises a primary supply including a first inlet 45, adapted to be connected to a cold mains water supply, a second inlet 46, adapted to be connected to a hot mains water supply, and a set of valves for controlling the water supply to the first outlet 42 and the second outlet 43. Cold mains water supply and hot mains water supply commonly refer to the pipes supplying running domestic water.

[0030] The controller 50 can, in particular, be used to control the mixer 40. The controller 50 typically includes actuators such as push buttons or These various actuators can be operated by a user and integrated, for example, into a control panel. In the illustrated example, the control panel 51 includes various push buttons, allowing the user to select the power supply for the hand shower 20 or the shower head 30, and the operating mode, as described later. Furthermore, the control panel 51, as illustrated, includes a temperature control, by which the user selects the desired temperature. The controller 50 is suitable for operating the various elements of system 1, and in particular the mixer 40, according to the settings applied via the control panel 51. The control panel 51 thus typically comprises a set of mechanical actuators that can be operated by the user. Alternatively, the control panel 51 can be a digital control panel.

[0031] System 1 as proposed also includes a water recycling circuit 100, allowing the water used to be recycled.

[0032] The shower tray 10 thus includes a tank 14, a valve 16 and a water level sensor 18.

[0033] The valve 16 is typically a solenoid valve controlled by the controller 50, and allows the water drain 12 to be selectively closed or not. Alternatively, the valve 16 is a mechanical valve or plug, coupled to a manual drain control 17.

[0034] The reservoir 14 is formed within the shower tray 10. It collects the water used during the operation of the shower system. The reservoir is typically positioned under a perforated grid 11 located within the shower tray 10, thus allowing easy access for cleaning. A filter 15 can also be positioned within the reservoir 14 to filter the water accumulated in the reservoir. The filter 15 is typically controlled by the controller 50 so as to be activated when the valve 16 is in the closed position. In other words, the filter 15 is typically disengaged when the user does not wish to activate the water recirculation function. The filter 15 can, in particular, be positioned at an inlet of the recirculation circuit 100 in the bottom of the reservoir 14. The water is then filtered as it is drawn by the pump 110 of the recirculation circuit 100.

[0035] The valve 16 is thus typically positioned in a bottom of the tank 14, so that the piloting of the valve 16 controls the filling or emptying of the tank 14 when using the shower system.

[0036] The water level sensor 18 is typically positioned in the tank 14, and is adapted to deliver information relating to the level in the tank 14 to the controller 50.

[0037] The tank 14 typically includes means adapted to maintain the water in the tank below a high threshold value. These means may in particular include an orifice connected to the discharge pipe at the top of the tank and performing an overflow function, and / or may be ensured by the association of the water level sensor 18 and the controller 50 which controls the valve 16 so as to make an excess of water flow towards the discharge pipe and to maintain the water level in the tank 14 between a threshold value and a high threshold value.

[0038] The system 1 typically includes a drain control 17 adapted to control the opening of the valve 16 and thus drain the tank 14. This drain control is typically a push button that can be operated by the user. Alternatively, the valve 16 is a solenoid valve controlled by the controller 50; in this case, the drain control 17 is not necessary and can be omitted.

[0039] The water recycling circuit 100 connects the tank 14 of the shower tray 10 to the mixer 40.

[0040] The mixer 40 thus includes a secondary inlet 41, connected to the recirculation circuit 100, and allowing water to be supplied to the mixer 40 by the recirculation circuit 100. The valve assembly of the mixer 40 allows, in particular, the supply of water to the first outlet 42 and / or the second outlet 43 via the primary inlet and / or via the secondary inlet 4L. In other words, the hand shower 20 and the overhead shower 30 can be supplied with water by the mains water circuit via the primary inlet, or via the recirculation circuit 100, or even via a combination of the mains water circuit and the recirculation circuit 100.

[0041] The recycling circuit 100 includes in particular a pump 110 and a heater 120.

[0042] The pump 110 is adapted to draw water from the tank 14 of the shower tray 10 and supply the mixer 40 via the heater.

[0043] The pump 110 is typically associated with a safety sensor 112, adapted to deliver a stop signal to the pump 110 when the water level in the tank 14 of the shower tray 10 is less than or equal to a safety threshold value. This safety sensor 112 thus defines a minimum water level to prevent a risk of cavitation of the pump 110.

[0044] The heater 120 is positioned between the pump 110 and the secondary inlet 41 of the mixing valve 40, and is configured to apply a heating setpoint to the water in the recirculation circuit 100 passing through it, in particular so that the water in the recirculation circuit 100 exiting the heater 120 is at a setpoint temperature. The heater 120 is typically controlled by the controller 50.

[0045] The controller 50 is configured to power the various elements of the shower system in order to define, in particular, a first operating mode and a Second operating mode. Alternatively, controller 50 can control the various elements. The function and nature of controller 50 depend in particular on the desired level of control, especially whether the system is to be primarily mechanically or electronically controlled.

[0046] In the first operating mode, the mixer is supplied by its primary supply, i.e., by the mains water supply. The valve 16 of the shower tray 10 is then typically open, so that the water drains through the drain pipe.

[0047] Alternatively, in the first operating mode, the valve 16 of the shower tray 10 can be closed, so as to collect the used water in the tank 14 of the shower tray 10. The water then accumulates in the tank 14 of the shower tray 10 until it reaches a threshold value, beyond which the excess water is discharged, either via the valve 16 or via a secondary orifice 13 connected to the drain pipe, thus acting as an overflow. The secondary orifice is typically formed on a promontory extending from the bottom of the tank 14, so as to be below the grid 11, the height of the promontory defining the high water threshold value in the tank 14. In this case, the first operating mode thus corresponds to conventional operation for the water supply, but also performs a water accumulation function in the tank 14.

[0048] The second operating mode corresponds to operation with water recycling. This second operating mode can notably be activated by the user, via an actuator coupled to the controller 50.

[0049] Initially, if the valve 16 is not in the closed position, the user controls the closing of the valve 16 so as to initiate a water accumulation in the tank 14.

[0050] The water level sensor 18 provides information about the water level in the tank 14 to the controller 50. In the second operating mode, the valve 16 of the shower tray 10 is closed. The used water thus accumulates in the tank 14 of the shower tray 10.

[0051] When the water reaches a threshold value, the controller 50 can be configured to output a signal informing a user that the water level in the tank 14 has reached the threshold value. The signal can be, in particular, an element displayed on a control panel, an audible signal, or a visual signal.

[0052] Optionally, system 1 thus includes a light source (or a light indicator) for delivering such a signal.

[0053] The user then typically operates the mixer 40 to cut off the supply from the primary network. The user then engages an actuator, typically a push button on a control panel 51, which activates The power supply to the pump 110 and the heater 120 by the controller 50 so as to put the recirculation circuit 100 into operation. The pump 110 is of the self-priming type when the operating mode with recirculation is selected, and does not require manual engagement by the user.

[0054] System 1 may include a hydraulic dynamo adapted to generate an electric current when system 1 is in operation, so as to power a light source, said dynamo being for example positioned at the secondary inlet 41 of the mixer 40, so as to indicate to the user that the secondary operating mode is engaged.

[0055] It is understood that in such an operating mode in which the user activates the secondary operating mode, the secondary operating mode can be engaged as soon as the water level in the tank 14 exceeds the safety threshold value. The user can thus typically activate the secondary operating mode when the water level in the tank 14 is between the safety threshold value and the threshold value. Alternatively, the controller 50 can be configured so as to only allow the pump 110, and therefore the second operating mode, to be activated if the water level in the tank 14 is greater than or equal to the threshold value.

[0056] Alternatively, the controller 50 performs a control function for the various elements so as to engage the second operating mode when the water reaches the threshold value, which is strictly greater than the safety threshold value. By way of non-limiting example, the safety threshold value could, for instance, correspond to a water volume of 2 liters, and the threshold value to a water volume between 6 and 8 liters.

[0057] In such a variant, the user can, for example, initiate the commissioning of the second operating mode. The controller then controls the valve 16 to fill the tank 14, and then the controller 50 controls the mixer 40, the pump 110, and the heater 120 to activate the recirculation circuit 100 and cut off the primary supply as soon as the water level in the tank reaches a threshold value.

[0058] The mixer 40, and in particular the mixer valve assembly 40, is thus controlled so as to supply water to the first outlet 42 and / or the second outlet 43 via the secondary inlet 4L. Thus, the hand shower 20 and / or the overhead shower 30 are supplied with water via the recycling circuit 100.

[0059] The pump 110 is configured to draw water from the tank 14 of the shower tray 10, and to supply the secondary inlet 41 of the mixer 40 via the heater 120.

[0060] The heater 120 is controlled to perform temperature control of The water from the recirculation circuit 100 passes through it. Thus, the controller 50 typically controls the heater 120 to assign a target temperature. The heater 120 then applies a heating or cooling setpoint so that the water leaving the heater 120 and reaching the secondary inlet 41 of the mixing valve 40 is at this target temperature.

[0061] The target temperature is typically selected by a user via a control panel associated with the controller 50. For example, a user can select the target temperature via a push button, a touchscreen, a dial, or any other suitable element. The target temperature can, in particular, be defined based on the temperature selected by the user via the mixer 40, for example via an actuator or a control of the mixer 40.

[0062] The shower system 1 is typically configured to be in its first operating mode by default. The second operating mode is typically engaged when a specific command is actuated, for example, by the user using an actuator associated with the controller 50.

[0063] In operation, a user can thus use the system according to the first operating mode to shower without recycling function.

[0064] The user can then initiate the filling of the tank 14 of the shower tray 10.

[0065] Optionally, the system emits a signal informing the user of the availability of the recycling function when the water level in the tank 14 of the shower tray 10 exceeds the threshold value.

[0066] The user can engage the recycling function, for example via an actuator associated with the controller 50. The controller 50 then compares the information provided by the water level sensor 18 in the tank 14 with the threshold value.

[0067] If the measured value is greater than or equal to the threshold value, the controller 50 drives the system to engage the second operating mode. If the measured value is less than the threshold value, the controller 50 maintains the system 1 in the first operating mode until the measured value exceeds the threshold value.

[0068] When the system is in the second operating mode, if the water level in the tank is below the safety threshold, the pump 110 is stopped to prevent any risk of cavitation. Alternatively, the controller 50 can then control the mixer 40 to re-engage the first operating mode and supply water via the primary circuit. Alternatively, a light signal or, where appropriate, a message can be displayed to inform the user of the low water level in the tank 14.

[0069] Alternatively, the system can also incorporate a hydro-massage jet function. Figures 5 and 6 are variants of Figures 2 and 4 described above incorporating such a function. The mixer 40 then typically includes a third outlet 44 adapted to supply a set of 60 hydromassage jets including in particular a set of nozzles shown in [Fig.6].

[0070] The user can then engage the hydro-massage jet function, for example, by operating a control.

[0071] According to one example, the hydro-massage jet supply is coupled to the secondary supply. Thus, the hydro-massage jet function can only be activated when the system is in the second operating mode, i.e., in operating mode with water recirculation.

[0072] The system as proposed thus makes it possible to carry out a recycling function for a shower, by offering a closed circuit operation for the supply of the hand shower 20 and the overhead shower 30.

[0073] The proposed system may in particular feature automatic activation of the recycling function if it is initiated by the user and the volume of water in the tank 14 is sufficient, without requiring additional manipulations by the user.

[0074] Furthermore, the heater 120 allows for the maintenance of the recycled water temperature, thus avoiding the need to add hot or cold domestic water for temperature maintenance. In addition, maintaining the recycled water temperature is more energy-efficient than adding domestic hot water.

[0075] Finally, the proposed system offers a simplified installation compared to existing systems. The integration of the tank 14 into the shower tray 10 eliminates the need for an external storage tank. Maintenance and servicing of the system are also facilitated by its structure. Furthermore, the proposed system allows for conventional shower operation without water recirculation, even in the event of an electrical failure or a component failure in the recirculation circuit.

[0076] Although the present invention has been described with reference to specific embodiments, it is evident that modifications and changes can be made to these examples without departing from the general scope of the invention as defined by the claims. In particular, individual features of the various embodiments illustrated / mentioned can be combined in additional embodiments. Therefore, the description and drawings should be considered in an illustrative rather than a restrictive sense.

[0077] It is also evident that all the characteristics described with reference to a process are transposable, alone or in combination, to a device, and conversely, all the characteristics described with reference to a device are transposable, alone or in combination, to a process.
