    [0002] Domestic hot water management device
    [0004] Technical field of the invention
    [0006] The present invention corresponds to the technical field of domestic hot water installations, which have a heater connected to a domestic hot water distribution network with a supply line, by means of a first cold water inlet line to the heater and a second line outlet of hot water to at least one supply point, and specifically to a domestic hot water management device connected to said installation and its operating mode.
    [0008] Background of the Invention
    [0010] At present, there is a use of energy in homes that is carried out on a daily basis and in which, inevitably and unconsciously, it is wasted in each use.
    [0012] This is the case of sanitary hot water supply facilities. These facilities have a heater to heat the water. Thus, when a user is going to use hot water, for showering or any other purpose, he opens the hot water tap at the point of supply and the heater is activated, so that the cold water from the supply network, it is introduced into the heater that, using different energy sources, which can be natural gas, butane gas, electricity ... they heat the water flow and send it through a conduit to the supply point.
    [0014] The problem arises when the user has finished using the domestic hot water and decides to close the stopcock. At this moment, there is a volume of hot water contained in the conduction section between the heater and the supply point, ready for use and that, when the stopcock is closed, it will no longer be supplied and therefore its temperature will drop and it will cool down. This volume of hot water contained in this section of the pipeline has consumed energy in the heater which, if it had been known in advance that the user intended to stop the use of hot water, could have been saved.
    [0015] It is therefore necessary to find a way to foresee the cessation of energy consumption invested in obtaining sanitary hot water before the user closes the supply point, being able to take advantage of the hot water from the pipeline for the final section of use , without overheating water. However, no mechanism or device has been found in the state of the art that manages to control this provision of cessation of the use of hot water.
    [0017] Description of the invention
    [0019] The sanitary hot water (DHW) management device, for a sanitary hot water installation that comprises a heater connected to a water distribution network that has a supply line, through a first cold water inlet line thereto and a second hot water outlet conduit to at least one supply point presented here, comprises a third connection conduit between the first and second conduits, connected to them externally to the heater, which allows a flow supply of cold water to the second pipeline and at least one first electrovalve with at least two ways, connected to the third pipeline, which allows regulating the supply of cold water to the second pipeline for a reduction or elimination of hot water flow to the point of supply.
    [0021] Likewise, this device has a control module arranged outside the heater, attached to the first and second pipes, which comprises control means formed by software connected to the at least one solenoid valve and electrical supply means connected to said control means and said at least one solenoid valve and remote actuation means of the control module.
    [0023] For its part, the control module comprises means of wireless communication with said means of remote actuation of the device.
    [0025] In this memory, a first operating procedure of a DHW management device, as defined here, is presented, which comprises a first stage of obtaining at least one sweep time for at least one supply point, corresponding to the time in seconds it takes for the cold water to circulate from the first conduit to said supply point, and a second stage of use, where the device comprises a first solenoid valve in the closed position.
    [0026] This second stage of use comprises a first stage of opening the tap at a hot water supply point followed by a second stage of using said hot water.
    [0028] Next, the third opening phase of the first solenoid valve takes place by means of a first activation of the actuation means, which is carried out by the user when he wishes to terminate the use of hot water.
    [0030] The fourth phase consists of injecting cold water into the second pipeline and simultaneously starting a sweep time countdown in the control means.
    [0032] This is followed by a fifth phase of sending the warning signal to the electronic device of the actuation means, of the beginning of the sweep time, so that the user is aware that the injection of cold water is starting and in a time equal to the sweep time it reaches the supply point.
    [0034] Then, once the sweep time (TB) countdown reaches the warning time, a sixth phase is performed consisting of sending a second warning signal to the electronic device by the control means.
    [0036] After said flushing time has elapsed, a seventh closing phase of the first solenoid valve is carried out by the control means and, finally, an eighth closing phase of the tap at the supply point.
    [0038] In this memory a second operating procedure of a DHW management device is proposed, with a device such as the one presented here, which has a first stage of obtaining at least one sweep time for at least one supply point, and a second stage of use, where the device comprises a first and a second solenoid valve in the closed position, and a thermostatic valve.
    [0040] The second stage of use in this case comprises a first stage of opening the first and second solenoid valves by means of a first activation of the actuation means, while the second stage consists of opening the tap at a water supply point. hot.
    [0042] Then the third phase is the use of hot water at the temperature set in the thermostatic valve.
    [0043] Subsequently, a fourth phase of closing of the second solenoid valve takes place, by means of a second activation of the actuation means and simultaneously starting a countdown of the sweep time in the control means.
    [0045] The fifth phase consists of sending a warning signal to the electronic device of the actuation means, of the beginning of the sweep time and, once the sweep time has elapsed, the sixth phase of closing of the first electrovalve takes place.
    [0047] Finally, a seventh phase consists of sending a warning signal of the end of use time, by the control means to an electronic device of the activation means.
    [0049] A third method is presented in this specification that comprises a first stage of obtaining at least one sweep time for at least one supply point and a second stage of use, where the device comprises a first solenoid valve in the open position and a mixing valve three-way.
    [0051] In this case, the second stage of use comprises a first stage of opening the position of the hot mixing valve by means of a first activation of the actuation means.
    [0053] The second phase consists of opening the tap at a hot water supply point and then the third phase of using hot water at the temperature set on the mixing valve takes place.
    [0055] This is followed by the fourth phase of closing the hot position of the mixing valve and opening its cold position, by means of a second activation of the actuation means and simultaneously starting a countdown of the sweep time in the means of control.
    [0057] The fifth phase consists of sending a warning signal of the start of the sweep time to the electronic device of the actuation means and, after said sweep time, the sixth phase of closing of the first solenoid valve takes place.
    [0058] Finally, a last phase consisting of sending a warning signal of the end of use time is carried out, by the control means to an electronic device of the activation means.
    [0060] With the DHW management device and its operating procedure proposed here, a significant improvement in the state of the art is obtained.
    [0062] This is so because a simple device is achieved that is installed externally to the heater and has an additional conduit and means of control of the water flow in the existing pipes, so that it is possible to inject a flow of cold water in a regulated way to the hot water conduction at a certain time prior to the cessation of hot water use by the user, so that when the cold water reaches the supply point it is just at the moment when the user ends the use of hot water and therefore, the conduction section between the heater and the supply point does not contain hot water but rather cold water injected. This means that as there is no remaining hot water in the pipeline, no energy has been consumed in heating a volume of water that is not going to be used and therefore energy consumption is optimized.
    [0064] This is achieved through the collaboration of the user who must activate the control means by means of their actuating means and a very practical and completely effective device that is simple to install and with which a significant saving in energy consumption is obtained. Heater.
    [0066] Being an external device to the heater, it is easily serviceable and repairs and maintenance are easy to carry out.

    [0087] Detailed description of a preferred embodiment of the invention
    [0089] In view of the figures provided, it can be seen how in a first preferred embodiment of the invention, the DHW management device proposed here is directed to a domestic hot water installation that comprises a heater (4) connected to a water distribution network that has a supply line (25), by means of a first cold water inlet line (1) thereto and a second hot water outlet line (2) to at least one supply point.
    [0090] This device comprises a third conduit (3) for connection between the first and second conduits (1, 2), connected to them externally to the heater (4), which allows a cold water flow supply to the second conduit (2) and, a first electrovalve (EV1) with at least two ways, connected to the third conduit (3), which allows regulating the supply of cold water to the second conduit (2) for a reduction or elimination of water flow hot to point of supply.
    [0092] In this way, by controlling the opening of this first solenoid valve (EV1), it is possible to regulate a supply of cold water to the second hot water conduit (2), from a certain moment so that the cold water reaches the supply point when the user intends to stop using hot water.
    [0094] The device also comprises a control module (5) arranged outside the heater, attached to the first and second pipes (1,2), which comprises control means formed by software connected to the first solenoid valve (EV1) and , electrical supply means connected to said control means and to said first solenoid valve (RV1). It is also equipped with one or more elements that can be via bluetooth, wifi or radio frequency modules and in other configurations it can comprise a physical interface. These modules provide IOT connectivity for remote control. The basic software allows its remote operation and by configuring different variables, other software versions allow its control through IOT home automation, data logger and Big data.
    [0096] On the other hand, in this first preferred embodiment of the invention, the electrical supply means are formed by a connection cable to the electrical network. In other embodiments, they can be formed by a manual mechanism with thermoelectric or piezoelectric materials or by a battery.
    [0098] The device also includes all the plumbing elements necessary for its assembly, as well as elements for connection to the installation.
    [0100] In turn, it comprises means of remote actuation of the control module, which in this first embodiment is a radio frequency command, but in other embodiments it may be formed by a Bluetooth or Wi-Fi mobile phone, or another associated system that depends on of communications systems that have a built-in control module with a power supply, a signal transmitter-receiver. In other modes The embodiment can include warning means, at least one sensor, an electronic control means, a communication interface and a power supply. These means of action are located next to the taps or showers.
    [0102] On the other hand, in this first preferred embodiment of the invention, the electrical supply means are formed by thermoelectric or piezoelectric materials, while in other embodiments it may be formed by batteries or a cable connected to the electrical network.
    [0104] As shown in Figure 1, in this first preferred embodiment of the invention the second and third pipes (2, 3) comprise a non-return valve (AR) respectively.
    [0106] In turn, this report presents a procedure for operating a DHW management device for this first embodiment. As shown in Figure 2, said procedure comprises a first and a second stage.
    [0108] The first stage (6) is to obtain at least one sweep time (TB) for at least one supply point, a warning time (TA) and a cut-off time (TC). The sweep time (TB) corresponds to the time in seconds that it takes for the cold water to circulate from the first line (1) to said supply point, while the warning time (TA) is less than the sweep time (TB), such that it serves as a warning to the user that the sweep time (TB) is going to end shortly and therefore the hot water will end. For its part, the cut-off time (TC) is a value set by the user to cut off the water supply of a third solenoid valve once the sweep time (TB) has ended.
    [0110] In this first embodiment, the warning time (TA) has a value such that it allows the user to be warned with some advance notice that there is little left for the scan time (TB) to end and in this case it has a value of 5 seconds lower than the sweep time (TB), but in other embodiments it may have a different value, since it is an adjustable value according to user preferences. For its part, the cut-off time (TC) in this first embodiment is considered to be 5 seconds as well, but in other embodiments different cut-off times can be considered, since again it is an adjustable value.
    [0111] For its part, the second stage (7) is the stage corresponding to the use of the device. This device in this first embodiment comprises a first solenoid valve (EV1) in the closed position.
    [0113] In this first embodiment, as shown in Figure 1, the device also comprises a third solenoid valve (EV3) with at least two ways, connected to the supply line (25), which allows the existence or absence of supply to be controlled of cold water to the network. In other modes it may not have this third solenoid valve (EV3).
    [0115] The second stage (7), as can be seen in Figure 2, comprises a first stage of opening the tap (8) at a hot water supply point, when the user wishes for example to take a shower. The second phase corresponds precisely to the use of hot water (9) by the user.
    [0117] At the moment in which the user intends to finish using the water because he is about to finish his shower, the third phase takes place consisting of the opening of the first solenoid valve (10) by means of a first activation (A1) of the actuation means by the user.
    [0119] When the actuation means are activated, the fourth phase of injection of cold water (11) into the second conduit (2) is carried out and simultaneously the start of a countdown (12) of the sweep time in the control means. That is, since the first solenoid valve (EV1) has been opened, it lets a volume of cold water pass to the second hot water line (2), so that in this second line (2) there is now a mixture of hot and cold water.
    [0121] This is followed by a fifth phase of sending the warning signal (13) to the electronic device of the actuation means, of the start of the scanning time. Thus, when this signal is sent, the user receives it in the electronic device and already knows that the sweep time has started, so that they can continue showering at the desired temperature, but knowing that once the sweep time ends the water that begins to reach the point of supply is colder mixed water.
    [0123] In this first embodiment, once the sweep time countdown (TB) reaches the warning time (TA), the control means send a second warning signal (18) to the electronic device, in this case five seconds before the end of the scan time, to notify the user of the end of the same.
    [0125] A sixth phase of closing of the first solenoid valve (14) and closing of the third solenoid valve (19) are then carried out simultaneously, after the purge time has elapsed. The closure of said third solenoid valve is carried out during a period of time equal to the cut-off time (TC) set in the first stage.
    [0127] Finally, a seventh phase of closing the tap (15) takes place, that is, it requires the user to act by closing the tap, otherwise the water would continue to flow.
    [0129] The third solenoid valve (EV3) once the cut-off time (TC) has elapsed returns to an open position to provide service to the network and be ready for a new cycle.
    [0131] In this specification a second preferred embodiment of the invention is proposed in which the DHW management device comprises a second solenoid valve (EV2) with at least two ways, connected to the second conduit (2), which allows controlling the existence or absence of hot water supply to the supply point.
    [0133] In this second embodiment, as shown in Figure 3, the device also comprises a third solenoid valve (EV3) with at least two ways, connected to the supply line (25), which allows the existence or absence of supply to be controlled of cold water to the network. In other modes it may not have this third solenoid valve (EV3).
    [0135] Likewise, as in the first embodiment, the second and third conduits (2, 3) comprise a non-return valve (AR) and the means for remote actuation of the control module and its electronic device are similar to those of the first embodiment.
    [0137] A procedure for operating a DHW management device is also proposed for this second embodiment. In this second mode, as already indicated, the device comprises, in addition to the first solenoid valve (EV1) in the closed position, a second solenoid valve (EV2) also in the closed position.
    [0138] The procedure for this second embodiment is similar to that set forth for the first embodiment, except in the second stage of use, which in this case comprises a phase prior to opening the tap (8) consisting of an opening of the second solenoid valve (16) by means of a first activation (A1) of the actuation means. With this, the passage of hot water from the heater (4) to the second conduit (2) is allowed, in order to supply hot water to the supply point when the tap is opened.
    [0140] As shown in Figure 4, the method in this second embodiment also comprises an intermediate phase of closing the second solenoid valve (17) by means of a second activation (A2) of the actuation means simultaneously with the opening phase. of the first solenoid valve (10). In this way, at the same time that the entry of cold water into the second conduit (2) starts, the supply of hot water to it is cut off and therefore, during the sweep time (TB) the user continues showering at the desired temperature, but hot water is no longer entering the second line (2), so energy consumption in its production has ceased.
    [0142] Thanks to the possibility of a second activation of the actuation means, to close the second solenoid valve (EV2), additional savings are allowed, since normally the second solenoid valve (EV2) arranged in the second conduit will be closed This prevents the opening of a tap for quick use from accidentally opening the hot water and filling the second line (2) with it, without giving it time to reach the supply point and remain for both inside said second conduit (2) wasting the energy used to heat it.
    [0144] Likewise, in this second embodiment, as in the first mode described, the procedure comprises a phase prior to the closing of the first solenoid valve (14) and in this case to the closure of the third solenoid valve (19), once that the countdown of the sweep time (TB) reaches the warning time (TA), consisting of sending a second warning signal (18) of the end of use time to the electronic device of the actuation means.
    [0146] Thus, and as shown in Figure 4, below, the device of the second preferred embodiment of the invention that comprises a third solenoid valve (EV3) that is in an open position, comprises in the second stage (7) of the This procedure closes said third solenoid valve (19) simultaneously with the closure of the first solenoid valve (14) after the purge time (TB) has elapsed. The closing of said third The solenoid valve is performed for a period of time equal to the cut-off time (TC) set in the first stage, after which the third solenoid valve (EV3) returns to an open position.
    [0148] On the other hand, in this second embodiment, the first stage (6) of the procedure comprises setting a maximum time value (TM) for the use of hot water and the second stage (7) thereof comprises after the opening of the tap (8), a control of the hot water use time. Thus, if this exceeds (21.1) the maximum time of use (TM), the device, automatically and without the possibility of user intervention, automatically closes (20) the second solenoid valve (EV2) and simultaneously opens of the first solenoid valve (EV1).
    [0150] If the time does not exceed the maximum use time (TM), the user continues to use the water until he decides to terminate and activates the closing of the second solenoid valve (17) simultaneously with the opening of the first solenoid valve (10 ), to initialize the sweep time (TB).
    [0152] Likewise, in this second embodiment, the first stage (6) of the procedure comprises setting a value of available time (TD) of hot water corresponding to the time in seconds that the closing of the second solenoid valve (EV2) is delayed in the second hot water conduit (2) once its closure has been activated and in the second stage (7) the closure of said second solenoid valve (17) by the control means takes place with a delay from the activation of the The same is equal to said hot water available time (TD).
    [0154] Thus, if the user is showering and the value of the sweep time (TB), which depends on the distance between the supply point and the heater, is insufficient to allow him to finish showering in that interval, the delay in the closing the second solenoid valve (EV2) allows you more relaxation to end the shower comfortably.
    [0156] This specification in turn proposes a third preferred embodiment of the invention in which the device, in addition to the first and second solenoid valves (EV1, EV2) with at least two ways, comprises a thermostatic valve (VT) which in this third embodiment has a temperature sensor and a flow meter.
    [0157] As shown in Figure 5, this thermostatic valve (VT) is arranged in the second conduit (2) prior to the second solenoid valve (EV2), such that it allows regulating the temperature of the water supplied to the supply point, where the third conduction (3) has a first branch (3.1) connected to the thermostatic valve (VT), to supply cold water to it and a second branch (3.2) connected to the second conduit (2), to inject cold water and achieving energy savings, such that the first solenoid valve (EV1) is connected in said second branch (3.2) of the third conduit (3).
    [0159] The thermostatic valve of this third embodiment provides an optimization of the water temperature. In addition, by consuming mixed water, the volume of water consumed in the heater is reduced, so the temperature drops less and therefore the ignition moment of the same is extended to reheat the water.
    [0161] In this third embodiment, the device comprises a third solenoid valve (EV3) with at least two ways, connected to the first conduit (1), which makes it possible to control the existence or absence of cold water supply to the system. This third solenoid valve (EV3) is optional, so in other embodiments the device may not have it.
    [0163] Likewise, as in the first and second embodiments, the second and third conduits (2, 3) comprise a non-return valve (AR) and the remote actuation means of the control module and the electronic device of the They are similar to those of the first embodiment.
    [0165] An operating procedure is also proposed for the device of this third embodiment which, as shown in Figure 6, comprises a first stage (6) for obtaining at least one scan time (TB) for at least one point supply, corresponding to the time in seconds it takes for the cold water to circulate from the first conduit (1) to said supply point and a warning time (TA), and a second stage (7) of use.
    [0167] In this case, the second stage (7) of the procedure comprises a first stage of opening the second solenoid valve (16) by means of a first activation (A1) of the actuation means, followed by a second stage of opening the tap (8) at a hot water supply point.
    [0168] The third phase consists of the use of hot water (9) at the temperature set in the thermostatic valve (VT). In this third embodiment, the user only needs to open the hot water tap at the point of supply, that is, it is not necessary to open the cold water tap at the same time or manipulate the mixer tap to mix cold and hot water at the same time. correct temperature, since the water reaches the supply point at the temperature previously selected by the user in the system and perfectly mixed by the thermostatic valve (VT).
    [0170] The fourth phase consists of the closing of the second solenoid valve (17), and the opening of the first solenoid valve (10) by means of a second activation (A2) of the actuation means and simultaneously the beginning of a countdown (12) of the time sweep (TB) in the control means. This fourth phase takes place when the user wants to end the use of hot water and is the moment in which he activates the closing of the second solenoid valve (EV2) and the flow of hot water to the point of supply is cut off, so when it ends the sweep time (TB) only reaches cold water to it.
    [0172] Next, a fifth phase of sending a warning signal (13) to the electronic device of the actuation means takes place, of the start of the scanning time.
    [0174] Next, the sixth phase is performed once the sweep time countdown (TB) reaches the warning time (TA), of sending a warning signal of the end of time (18) of use, by the means of control to an electronic device of the activation means.
    [0176] Finally, a seventh phase of closing of the first solenoid valve (14) takes place, after the flushing time (TB) has elapsed, thus cutting off the flow of cold water to the supply point and an eighth phase of closing the tap (15 ).
    [0178] This device comprises a third solenoid valve (EV3) that is in an open position, but in this third embodiment, the second stage (7) of the procedure does not require a closing phase of said third solenoid valve (19) as there is no risk cold water comes out of the tap. In this third mode, the third solenoid valve (EV3) has the function of being able to close the supply line (25) and therefore the entry of water into the distribution network, in those situations that are of interest, for example when being outside the home, to avoid dripping taps or water leaks. Thus, the user can close this third solenoid valve remotely, when a flow meter installed in the network indicate unwanted consumption, if there is a leak, or any other situation that would advise a network supply cut-off.
    [0180] Thus, in this case, the procedure presents a third stage (27) subsequent to the first stage (6) and which takes place alternatively with respect to the second stage (7) and which takes place when the user wishes to close the entrance of water (22.1) to the network, by means of the electronic device and remotely, you can activate the closing (19) of this third solenoid valve (EV3) during a certain time of non-use of the distribution network, because it will be outside the For example, when you want to use the network (22.2), you activate the opening (23) of the third solenoid valve (EV3) again, to allow water to enter the device.
    [0182] As can be seen in Figure 6, in this third embodiment, the procedure also comprises setting a maximum time value (TM) for hot water use in the first stage (6) and, in the second stage (7 ) comprises an automatic closing phase (20) of the second solenoid valve (EV2) automatically by means of the control means, in the event that said maximum time (TM) is exceeded (21.1) during the use of hot water (9). If this maximum time is not exceeded (21.2), it is the user who activates the closure of the same when he wants to end use.
    [0184] Likewise, in this third embodiment, the first stage (6) the procedure comprises setting a value of available time (TD) of hot water corresponding to the time in seconds that the closing of the second solenoid valve (17) is delayed in the second hot water conduit (2) once its closure has been activated and in the second stage (7) the closure of said thermostatic valve (17) by the control means takes place with a delay from the activation of the same equal to said time available for hot water. In this way, since the value of the sweep time (TB) depends on the distance between the supply point and the heater (4), it may happen that it is too small a value and does not allow enough time to finish the use that is taking hot water. In this case, the delay in closing the second solenoid valve (EV2) allows greater comfort and relaxation at the end of this use.
    [0186] In this third embodiment, in which the device has a first activation for the opening of the first and second solenoid valves (EV1, EV2) and a second activation for the closing of the second solenoid valve and start of the sweep time (TB) allows additional savings consisting of avoiding unwanted energy consumption It is carried out in installations with a mixer tap when they are opened hot by mistake, for example when the user is going to wash their hands. In these cases, with installations without this device, the second line is filled with hot water that is not going to be used, since the consumption to be carried out is short. However, with this device the installation presents, in the idle situation, the second solenoid valve arranged in the second conduit in the closed position, so that the conduit is prevented from filling with unwanted hot water.
    [0188] Only when the user is aware that he wants to use hot water for a long time, does the process start through the first activation that opens this second valve.
    [0190] This specification also presents a fourth embodiment of the DHW management device in which, in addition to the first solenoid valve (EV1) arranged in the third conduit (3), it comprises a three-way mixing valve (VM) that has a temperature sensor and a flow meter. As shown in Figure 7, this mixing valve (VM) is located in the second conduit (2), such that it allows controlling the existence or absence of hot water supply to the supply point and regulating its temperature.
    [0192] The mixing valve has the same advantage as the thermostatic valve of the device proposed in the third previous embodiment, consisting in that it provides an optimization of the water temperature and consumes mixed water, thereby reducing the volume of water consumed in the heater. .
    [0194] As in the second and third proposed embodiments, in this case the device comprises a third solenoid valve (EV3) with at least two ways, connected to the first conduit (1), which makes it possible to control the existence or absence of supply of cold water to the system. Likewise, the second and third conduits (2, 3) comprise a non-return valve (AR).
    [0196] In turn, an operating procedure is proposed for the device of this fourth embodiment that comprises a first step (6) of obtaining at least one scan time (TB) for at least one supply point and a warning (TA), and a second stage (7) of use comprising a first phase of opening the position of the hot mixing valve (28) by means of a first activation (A1) of the actuation means, followed by a second phase of opening the tap (8) at a hot water supply point and a third phase of using hot water (9) at the temperature set in the mixing valve.
    [0198] As shown in Figure 8, in this fourth embodiment, when the user wishes to end the use of hot water, a fourth phase of closing the hot position (24) of the mixing valve and opening of the position takes place. cold thereof, by means of a second activation (A2) of the actuation means and simultaneously starting a countdown (12) of the sweep time (TB) in the control means.
    [0200] A fifth phase of sending the warning signal (13) to the electronic device of the actuation means is then carried out, of the start of the sweep time.
    [0202] When the sweep time countdown (TB) reaches the warning time (TA), a sixth phase of sending a warning signal of the end of use time (18) takes place, by the control means to a device electronic means of activation. Finally, a seventh phase of closing of the first solenoid valve (14) is carried out, after the sweep time has elapsed, cutting off the passage of cold water to the supply point. Finally, the user closes the tap and opens the first solenoid valve (10) for the next cycle.
    [0204] In this fourth embodiment, as in the third embodiment described, the third solenoid valve (EV3) is in an open position, and the second stage (7) of the procedure does not require a closing phase of said third solenoid valve. (19) as there is no risk of cold water coming out of the tap. Again, in this fourth mode, the third solenoid valve (EV3) has the function of being able to close the supply line (25) when this is required and the supply network is not going to be used. Thus, the procedure presents a third stage (27) alternative to the second stage (7), in which when the user wishes to close the water inlet (22.1) to the network, by means of the electronic device and remotely, he activates the closing (19) of this third solenoid valve (EV3) and when it wants to make use (22.2) of the network, it reactivates the opening (23) of the third solenoid valve (EV3) and from that moment on the second stage can take place (7) of device use.
    [0206] Likewise, the first stage (6) comprises setting a maximum time value (TM) for hot water use and the second stage (7) comprises an automatic phase (26) for closing the hot position of the valve mixer and opening the cold position of the itself, arranged in the second conduit (2) by means of the control means, if said maximum time (TM) of hot water use is exceeded (21.1).
    [0208] If this maximum time of use (TM) is not exceeded, it is the user who activates the closure by the control means when he wants to end the use.
    [0210] The described embodiments constitute only examples of the present invention, therefore, the specific details, terms and phrases used in the present specification are not to be considered as limiting, but are to be understood only as a basis for the claims and as a representative basis that provides an understandable description as well as sufficient information to the person skilled in the art to apply the present invention.
