Definitions

  • the present invention relates to an automatic system and a method for flushing a sanitary bowl.
  • an automatic flushing system of a sanitary bowl includes a sensor, such as a contact or presence sensor, and an electronic control board connected to the sensor; based on the signals received from the sensor, the electronic board controls the turning on and off of a water supply tap or, if a cistern is used, it activates a cistern flush valve actuator.
  • a sensor such as a contact or presence sensor
  • an electronic control board connected to the sensor; based on the signals received from the sensor, the electronic board controls the turning on and off of a water supply tap or, if a cistern is used, it activates a cistern flush valve actuator.
  • the known automatic systems generally have the drawback of flushing a single predefined quantity of water, and do not allow the selection of the amount of water to be flushed as needed, namely depending on the functions performed by the user.
  • Saving water is instead an increasingly felt need, as is that of using dual-flush flushing valves, able to selectively flush two different amounts of water: the user can decide whether to actuate the complete flush or partial flush as needed, i.e. depending on the physiological functions performed.
  • One purpose of the present invention is thus to provide an automatic method and system of flushing a sanitary bowl which overcome the drawbacks mentioned above of the prior art.
  • one purpose of the invention is to provide a system and a method permitting the automatic actuation of flushing in two flushing modes, selected according to the functions performed by the user.
  • the present invention thus relates to an automatic flushing system of a sanitary bowl and a method of flushing a sanitary bowl as defined in essential terms in the appended claims 1 and 13, respectively, as well as, for the additional preferred characteristics, in the dependent claims.
  • the invention permits the actuation of flushing of the sanitary bowl in a fully automatic manner without requiring the intervention of the user, and according to two different flushing modes (for example, complete flush and partial flush) selected, again automatically, as appropriate.
  • the system of the invention automatically recognizes the type of physiological function performed by the user and selects the appropriate flushing mode (complete or partial) as a result.
  • reference numeral 1 globally denotes an automatic flushing system of a sanitary bowl 2.
  • the bowl 2 is connected by a water supply tube 3 to a cistern 4, for example of the flush mounted type (i.e. recessed in use in a wall).
  • the system 1 comprises a flushing valve 5, placed in the cistern 4 and connected to the tube 3 so as to act on the tube 3, in particular to open/close a through hole between the cistern 4 and the tube 3; and a flushing control device 6, acting on the flushing valve 5 to open/close the flushing valve 5.
  • the cistern 4 and the flushing valve 5 may be of the known type and are therefore not shown in detail for the sake of simplicity.
  • the flushing valve 5 has a mobile obturator 7 acting in conjunction with a flushing hole 8 of the cistern 4; for example, the obturator 7 is placed at a lower end of an overflow pipe 9 of the cistern 4.
  • the flushing valve 5 is designed to operate alternately according to two different flushing modes in which two different quantities of water are flushed: in particular, the flushing valve 5 is a dual-flush flushing valve able to selectively actuate a complete flush and a partial flush of the water contained in the cistern 4.
  • the device 6 comprises a control unit 11, an actuator 12, controlled by the control unit 11 and acting on the flushing valve 5 and precisely on the obturator 7, and an acoustic sensor 13 connected to the control unit 11.
  • the control unit 11 is for example an electronic board (known), supported for example (but not necessarily) by a control plate 14 of the wall-mounted type in front of the cistern 4 closing an inspection opening of the cistern 4.
  • the actuator 12 is for example an electromechanical actuator connected to the obturator 7 to move the obturator 7 and thus open/close the flush hole 8 and thus the flushing, valve 5 (and thereby actuate one or other flushing modes).
  • the acoustic sensor 13 is for example a microphone and can be positioned in the bowl 2, especially on a side wall of the bowl 2, or near the bowl 2 or in another position in the room where the bowl 2 is situated, for example on the control plate 14, inside the cistern 4, in particular inside the overflow pipe 9, etc.
  • the acoustic sensor 13 may be equipped with a support or attachment member to attach the acoustic sensor 13 in the desired position on the bowl 2 or other support surface.
  • the acoustic sensor 13 is connected to the control unit 11 to send signals to the control unit 11.
  • the drawing does not show the connections between the control unit 11 and the acoustic sensor 13, nor generally between the various components of the system 1, nor the electrical connections for the power supply of the components of the system 1.
  • the components of the system 1, in particular the control unit 11 and the acoustic sensor 13, may be connected in any known way with or without wires, for example in any wireless type connection, such as Bluetooth etc.
  • control unit 11 is configured to actuate one or other flushing mode of the flushing valve 5 (i.e. complete or partial flushing of the water in the cistern 4) depending on whether the acoustic sensor 13 detects a first or a second type of noise.
  • the system 1 also comprises a proximity sensor 15, for example a microwave sensor, able to detect the presence of a user at a predefined distance from the proximity sensor 15 and connected (wired or any wireless type connection such as Bluetooth etc.) to the control unit 11.
  • a proximity sensor for example a microwave sensor, able to detect the presence of a user at a predefined distance from the proximity sensor 15 and connected (wired or any wireless type connection such as Bluetooth etc.) to the control unit 11.
  • the proximity sensor 15 is placed on the control plate 14.
  • the control unit 11 also controls a display 17 and a plurality of LEDs 18, for example also placed on the control plate 14 (only two LEDS 18 are shown, by way of example, in the drawing).
  • the display 17 provides the user with operating information about the system 1, in particular the water consumption; and/or any other type of information or message, by means of images, photographs, graphics, captions, drawings etc.
  • the LEDs 18 can switch on, controlled by the control unit 11, in different light patterns in order to provide different lighted messages.
  • the LEDs 18 are arranged around the display 17 to form a closed loop frame 19.
  • the LEDs 18 are able to provide light of different colours.
  • the system 1 comprises then, preferably, also a pair of manual commands 20 to actuate the flushing valve 5 in the respective flushing modes in case of malfunction of the automatic system 1.
  • the commands 20 comprise a pair of capacity sensors, placed for example on the control plate 14, which command, again through the control unit 11, the actuator 12.
  • the system 1 works, in implementation of the flushing method according to the invention, as follows.
  • the proximity sensor 15 detects the presence of the user and sends a presence signal to the control unit 11.
  • the control unit 11 activates the acoustic sensor 13 which starts to detect noises.
  • control unit 11 may also command the LEDs 18 to switch on in one colour or according to established patterns.
  • the acoustic sensor 13 detects the noise generated by the user in performing the physiological functions, namely the noise generated by contact of the faeces or urine with the water in the bowl 2 and/or the walls of the bowl 2.
  • the acoustic sensor 13 sends a corresponding signal, representative of the noise detected, to the control unit 11.
  • the control unit 11 processes the signals representative of the noise received from the acoustic sensor 13 and discriminates the signals received from the acoustic sensor 13 into a first and a second type of noise by comparing the signals received with sample signals stored in the control unit 11.
  • control unit 11 contains programmes to analyse the fundamental frequencies of the signals received from the acoustic sensor 13 and compare the fundamental frequencies identified with sample frequencies stored.
  • the control unit 11 thus recognises if the noise detected by the acoustic sensor 13 is associated with the expulsion of faeces or urine.
  • the control unit orders the intervention of the actuator 12 on the flushing valve 5 to actuate one or other flushing mode (i.e. complete or partial flush) depending on the type of noise detected.
  • the control unit 11 also controls the switching on of the display 17 and of the LEDs 18 to provide information and messages to the user.
  • control unit 11 shows on the display 17 water consumption information, or other operating information on the system 1, and switches on the LEDs 18 to selectively provide a first or a second light message corresponding to the flushing mode actuated.
  • control unit 11 switches on the LEDs 18 all along the frame 19 if a complete flush has been actuated, and only some of the LEDs 18, for instance along only one half of the frame 19, if partial flushing has been actuated.
