    DESCRIPTION
    DEVICE FOR A SEAT OF A TOILET WITH BIDE FUNCTIONS, AND TOILET AND TOILET SEAT THAT INCLUDES SUCH DEVICE
    The present invention relates to a device for a toilet seat with bide functions and a toilet and toilet seat comprising said device. In particular, the present invention relates to a device for a toilet seat with bide functions that complies with European standard EN 1717 for protection against contamination by reflux of water from sanitary facilities.
    Background of the invention
    In the European market there is a wide variety of toilets with bide functions, also known as electronic bides. These toilets or electronic bides incorporate in the seat a device with a duct or water discharge cannula for anal and / or perineal washing and, usually, also a drying unit. The heating of the washing water that the cannula discharges is carried out by means of an intermediate tank or water tank that incorporates a heat source.
    Some toilet devices with bide functions described in the previous paragraph incorporate means to prevent contamination by reflux of sewage and comply with European standard EN 1717 for protection against contamination of sanitary facilities. However, they have the disadvantage that their seats are very bulky and high, so that their installation is very unattractive for the user. The aforementioned European regulations require that the intermediate reservoir of the wash water in the supply network be hydraulically isolated. However, it has been observed that this determines the design of the seats.
    EP2447426 describes a toilet with bide functions compatible with European standards but with a seat of about 100 mm high that is very high and bulky for the user. This toilet incorporates an intermediate tank or tank that heats the wash water and is partly inserted into a cavity of the porcelain bowl of the toilet. This detail determines the design of the cup.
    In view of the above, it is clear the need to provide a toilet with

    functions of bide, of compact design and seat of similar appearance to that of a conventional toilet, and that at the same time complies with the European norm EN 1717 for the protection against contamination by reflux of sewage.
    Description of the invention
    The aim of the present invention is to provide a device for a toilet seat with bide functions that has the advantages that will be described below.
    In accordance with this objective, according to a first aspect, the present invention provides a device for a toilet seat with bide functions, comprising a water discharge conduit for anal and / or perineal washing, and means for preventing contamination by reflux of the water of the network that supplies said discharge duct. The device is characterized by the fact that it comprises a tank for storing and heating the washing water that discharges said duct, which includes;
    to. A water inlet that is located above the water level (h) of the tank and an overflow to give water out when the water level in the tank exceeds a predetermined height (hmax), allowing to avoid this water inlet and the overflow pollution from sewage reflux,
    b. a water outlet that is connected to the discharge duct through a water supply pump,
    C. a circuit to force a predetermined path of water from said inlet to said outlet, said circuit being associated with a heat source to heat the water during its travel, and
    d. at least one level sensor to emit a signal when the water level (h) of the tank drops,
    said device comprising a processing and control unit configured to order the entry of water into the reservoir based on the signal emitted by said level sensor, and adjust the power of the circuit heat source as a function of a signal emitted by a water temperature sensor and / or by a user presence sensor.
    According to a second and third aspect, the present invention relates to a seat and a toilet, which incorporates the claimed device, and which have the advantage that they are of compact design and look very similar to that of seats and toilets.

    Conventionals that do not have bide functions.
    The present invention has the particularity that the storage and heating of the washing water of the discharge duct is carried out in a tank of limited height by an overflow to give water outflow in case of reflux, and a water inlet that is located above the water level of the tank.
    The overflow exits the water when the tank level exceeds a predetermined height, for example, a height (hmax) between 15 mm and 40 mm, and the water inlet of the tank is located at least 20 mm above the maximum level (hmax) of water from the tank to avoid contamination in case of reflux.
    The claimed tank incorporates at least one level sensor capable of sending a signal to a processing and control unit to order the entry of water when the water level drops, when a discharge of wash water occurs. To heat the water, the tank incorporates a circuit that forces the water path from the entrance to an exit. This circuit is associated with a heat source, for example, an electrical resistor to heat the water during the journey. A processing and control unit adjusts the power of the heat source of the circuit based on a signal emitted by a temperature sensor and / or a user presence sensor. This presence sensor can be, for example, a capacitive sensor mounted on the toilet seat, or an infrared sensor.
    Thanks to these characteristics, a device for a toilet seat is obtained which, on the one hand, complies with the European protection regulation EN1717, since the overflow can eventually give way to contaminated water in case of reflux, and on the other hand, It allows a design of the toilet seat of reduced height and capacity without losing efficiency in the supply of hot washing water.
    Indeed, although the device described has the particularity that the storage of the washing water is carried out in a tank of height and capacity limited by the overflow and the seat support itself, the heating of the water can be carried out in a very efficient way and in a very short response time (less than 50 seconds), since the heating circuit is configured to ensure heating while the level sensor associated with the processing and control unit constantly maintains the water level when it occurs

    a discharge of wash water.
    The devices of the state of the art with deposits that incorporate heating resistors have an average response time (water heating time when the user presence sensor is activated) that is normally greater than 2 minutes, while in the present invention this Time is always less than 50 seconds. In addition, as already mentioned, in some devices of the state of the art, the hot water tank or tank is partially inserted in a cavity of the toilet bowl, so that the design of the toilet bowl is conditioned by the water heating tank.
    According to a preferred embodiment, the capacity of the water storage and heating tank is less than 0.5 l, preferably, less than 0.35 l, and advantageously, the water heating circuit is associated with a heat source comprising a heating element (for example, an electrical resistor) configured to apply a power inside the tank greater than 1500 W.
    It has been observed that this power is necessary to ensure a thermal jump of water of up to 30 ° C and a discharge (Qs) of wash water greater than 0.5 l / min, for example, of up to 1 l / min. The heating element can preferably be designed as a tubular electrical resistance with a predetermined length depending on the energy density to be applied to achieve the desired thermal jump at the end of the path.
    Preferably, the pump that drives the water through the discharge duct or cannula is configured to provide a discharge flow rate (Qs) between 0.5 l / min and 1 l / min. This flow is necessary to provide adequate cleaning sensation to the user.
    Advantageously, the water storage and heating tank itself configures a first module of a device support piece that is sized to be mounted on the top plane of the toilet bowl without being inserted into a cup cavity .
    Indeed, the claimed device can be mounted in a seat without resorting to a specific cup design as it happens in some of the state-of-the-art devices, which include cavities to partially accommodate the storage tank.

    water storage and heating. Advantageously, the tank of the claimed device is integrated into the interior space of a housing whose dimensions do not exceed 75 mm in height, whereby the device can be mounted and disassembled on the top plane of the toilet bowl without needing to be partially inserted into the cup.
    Preferably, the flushing water discharge duct is mounted on a second module of the device support part and, optionally, the device may include a drying unit for the toilet user that is mounted on a third module of said device. support piece
    This modular configuration facilitates the assembly and disassembly of the device components. In addition, by configuring the device itself a module of the device, a very simple, compact and small-sized design is obtained.
    Advantageously, said device support piece incorporates a metal portion configured to dissipate heat from a switch associated with the heating element that provides the heat source. This metal portion may be in contact with the porcelain of the cup when the seat support is mounted on the top plane of the cup.
    According to a preferred embodiment, the discharge line of the wash water is a cannula that can be displaced with a substantially curved longitudinal profile. This cannula is mounted on a module of a device support piece that is sized to be mounted on the top plane of the toilet bowl. The cannula moves out of the support to a position of use when the user activates the motor that drives it.
    The curved profile contributes to obtaining a very small seat design height, which becomes less than 60 mm. Thanks to this, a seat that looks very similar to the one mounted on a conventional toilet without bide functions is obtained.
    The present invention also relates to a seat comprising the claimed device, and a seat ring and a toilet lid that are articulated and removable to a housing of the support part of the claimed device.

    Similarly, the present invention relates to a toilet with bide functions comprising the seat with the claimed device, and a body that acts as a cup on which said seat is mounted. The body or bowl of the toilet comprises a recess through which the discharge duct or cannula emerges from the device for carrying out the washing.
    In the present invention, a heating element will be understood as a conventional resistor element, for example, a tubular electrical heating resistor or, alternatively, an instantaneous electrical heating resistor, such as a ceramic type resistor.

    Description of a preferred embodiment
    The following describes a preferred embodiment of the device of the present invention incorporated in a toilet seat with bide functions that complies with European standard EN 1717 for the protection of sanitary facilities against reflux contamination.
    Figure 1 shows an exploded view of the seat 1 incorporating the claimed device 2. This device 2 comprises a reservoir 4 for storing and heating the washing water, a duct or cannula 5 for discharging the washing water from the tank 4 and a drying unit 6. The discharge cannula 5 has a curved longitudinal profile and can be moved from a collected interior position to an external position for use to carry out the washing (see figure 5).
    As can be seen in Figure 1, in the embodiment described the device 2 is mounted on a support piece that is modular and has three differentiated modules;
    • A first module 3a that configures the water storage and heating tank 4 itself for perineal and / or anal washing,
    • A second module 3b in which the washing water discharge cannula 5 is mounted, and
    • A third module 3c in which the drying unit 6 and a processing and control unit 7 of the device 2 are mounted.
    As can be seen in detail in Figure 2, the first module 3a of the support piece configures the storage and heating tank 4 of the washing water in which the heat source is housed. This tank 4 has the particularity that incorporates;
    • an overflow 8 to exit the water and prevent contamination by reflux when the water level (h) exceeds a predetermined height (hmax),
    • A water inlet 9 that is located above the water level of the tank,
    • An outlet 10 that is connected to the discharge cannula 5 through a pump
    8
    5
    10
    fifteen

    35
    11 water drive,
    • A circuit 12 to force the water path from inlet 9 to outlet 10,
    Y
    • a level sensor 13 to emit a signal when the water level (h) of the tank 4 drops.
    In the embodiment described the height of the overflow 8 has been set at 25 mm and the water inlet 9 is located at least 20 mm above the water level, so that if the water in the tank becomes contaminated, it can never reach to the drinking water network.
    As can be seen in Figures 2 and 3, the water storage capacity of the tank 4 is very small, for example, 0.30 l, so that this tank is very easy to integrate inside a housing 21 of the device 2 that is coupled to the modules 3a, 3b, 3c of the support piece and that is associated with the seat 1 of the toilet 15. The substantially curved longitudinal profile of the cannula 5 also helps facilitate the integration of the device 2 into a seat 1 of very reduced height, such as that shown in Figures 6 to 8 (approximately 60 mm high).
    In order to carry out the heating of the wash water, the heating circuit 12 of the tank 4 incorporates a tubular electric resistor 14 to apply a power of about 1650 W (see figure 4). This power is adequate to ensure the heating of the washing water of the network and at the same time the supply of an outlet flow of the water pump 11 of 1 l / min. This flow is necessary to provide adequate cleaning sensation to the user.
    As mentioned in the description of the invention, the claimed device 2 allows hot water to be supplied in a very short response time (less than 50 seconds), thanks to the combined action of said heating circuit 12 and the sensor 13 of the tank level 4 that is associated with a processing and control unit 7 configured to order the water inlet every time the water level drops. This same processing and control unit 7 adjusts the power of the resistor 14 of the circuit 12 as a function of a signal emitted by a temperature sensor and / or a user presence sensor, through a phase control. This phase control applies a percentage of resistance power 14 as a function of an algorithm based on a PID (Proportional Integral Derivative) control.
    In the claimed device 2, when the sensor detects the presence of a user, the
    9
    5
    10
    fifteen

    25

    35
    processing and control unit 7 activates the electrical resistance 14 of the circuit 12 so that in about 30 seconds the reduced volume of water in the tank (0.30 l) acquires the desired temperature. When the user activates the discharge of water through the cannula 5, the processing and control unit 7 immediately enables the entry of water from the network that is controlled by the level sensor 13, while the circuit 12 goes forcing the path of the incoming water to the outlet 10 to ensure its heating with a high power electric resistance 14.
    The devices of the state of the art existing in the European market that use tubular electrical resistors have the disadvantage that they have response times for the supply of hot water from the tank of about two minutes, or more than two minutes. However, these times are too long for the user of the toilet, so, in practice, the user ends up using water below the desired temperature.
    Figures 6 to 8 show a toilet 15 with bide functions incorporating a seat 1 comprising the claimed device 2. The seat 1 has a cover 16 and a seat ring 17 that are articulated and removable in connection with the housing 21 of the device 2 which is coupled to the three modules 3a, 3b, 3c of the support piece. The user presence sensor is disposed on this housing 21, which in the embodiment described is an infrared sensor 22.
    As can be seen in Figures 6 and 7, the modules 3a, 3b, 3c of the support piece of the device 2 are sized so that they can be mounted on the upper plane 18 of the toilet bowl 19 15. The housing 21 of the device 2 that is coupled to the aforementioned modules 3a, 3b, 3c, has a hole 21a through which the cannula 5 for discharging the wash water emerges when in use position. The cup 19 has a recess 20 to allow the cannula 5 to exit through the hole 21a of the housing 21.
    The present invention provides a seat 1 for a toilet 15 with bide functions having a plurality of advantages;
    • has a very short response time for the supply of hot washing water, less than 50 seconds,
    • has a design of reduced height, less than 75 mm when the cover 16 is closed on the seat ring 17 (see figure 9) and,
    • Complies with European standard EN 1717 for protection against
    10
    contamination by reflux of water from the network.
    Although reference has been made to a specific embodiment of the invention, it is evident to a person skilled in the art that the device 2 described is susceptible of numerous variations and modifications, and that all the mentioned details can be replaced by others technically equivalent, without departing from the scope of protection defined by the appended claims. For example, although in this description reference has been made to an electric resistor 14 as a heat source for the washing water heating circuit 12, alternatively, it would also be possible to use a ceramic ceramic resistor to instantly heat the water from reservoir 4 by an alternative wash water circuit.
