Definitions

  • the present invention generally relates to means and devices used in toilets or lavatories, and particularly relates to means used for automatically raising and lowering the toilet covering lids and, more specifically, relates to a hydraulic drive device for raising and lowering the covering lid and seat of a toilet.
  • toilets are commonly shaped in such a way that structurally comprise a bowl consisting of a body with a central hollow round or oblong hole, with an internal trap that discharges to a base fixed to the floor where the exit of the trap is connected to the sanitary drainage network, said bowl comprises an upper tank where a volume of water is deposited, which is connected through a duct to said bowl, wherein said ducts comprise a ball-cock supply valve with actuating means for discharging water into the bowl.
  • a water supply duct from a water supply source of a domestic network or public network connects directly into the water storage upper tank comprising a control bypass valve, wherein said tank includes valve means controlled by a float element to control the water volume to be stored and fed to the toilet, so as to dislodge urine and/or feces.
  • the rear part of the toilet bowl hole comprises some orifices where fixing means of a swinging lid and seat that cover the hole are inserted, which are disposed over the hole for hygiene reasons, preventing the user from direct contact with the toilet surface, as well as to provide greater comfort to the user.
  • the covering lid of the bowl consists of a solid body in a similar shape to the hole (round or oblong) and the seat has an annular or elliptical shape that follows the contour of the bowl hole, some seats are shaped like a horseshoe. Said seat is used so that people sit over it and avoid the direct contact with the bowl surface; in some cases the seat is padded for comfort, while the lid covers the bowl hole.
  • the existing problems are well known, such as when a man is trying to urinate, usually (if he has good manners), lifts with his hands both the lid and the seat to avoid splashing the seat with urine and to keep the seat clean, with the sanitary implications already indicated due to the direct contact of the hand with the lid and seat.
  • men when the lid is covering the bowl hole, just lift the lid, or if the lid is lifted, no longer finds it necessary to lift the seat, which when they urinate, leads to splashing and wetting with the seat with urine, causing displeasure to other users of the toilet and causing contamination of the lid that could be a source of infection for other users.
  • the device generally comprises a rotation shaft placed under the toilet seat and is attached to or makes contact with the same; a lever attached to the rotation shaft and moved by a user so as to transmit its movement to the rotation shaft, which being attached to the seat or making contact with it, achieves the desired motion of ascent or descent of the seat, the rotation shaft that is hosted on channels or ducts of the existing hinges formed by the lid, the seat and the toilet hinge brackets or is housed along of a housing provided on a support base fixed to the mounting orifices existing in the back part of the toilet ring.
  • Any member of the toilet (lid or seat) can be controlled with the hydraulic system associated with a control valve that directs water to one of the ports of the cylinder, while the other port that moves the piston rod in a first direction receives water from the extractor, moving to the toilet member (lid or seat) rotationally in one direction.
  • the toilet member lowers the control valve to reverse the cylinder ports that receive and deplete the water that makes the piston rod to move in a second direction by which the rotating toilet member is moved in the other direction.

  • the device is powered by a network of water supply pipes, the supply of which is regulated by three-way solenoid valves, two left and right motion sensors and a central presence sensor in communication with a circuit board that processes the sensor signals so as to actuate said solenoid valves.
  • This embodiment then consists of two supply ducts connected to a duct diversion from the main supply source into the toilet water tank and into one way of the two three-way solenoid valves arranged on the sides of the back part of the bowl; in the second solenoid position, the supply duct is connected to the pivot of the left and right diaphragms, and in the third solenoid position, the water discharge ducts of the diaphragms are connected from the solenoids to a main discharge duct that discharges into the toilet water tank.
  • the diaphragms only have a pivot where the working fluid enters and leaves.
  • the left and right motion sensors, the central presence sensor and the circuit board are housed within the driving device housing, the sensors being exposed at the upper front part of the device housing; said circuit board is connected to solenoid valves to activate them as needed by the hydraulic system.
  • the device In operation, in different work settings, as indicated above, the device operates as follows:
  • the Premium version device can lift the lid or the seat and lid at the same time by water pressure.
  • To lift only the lid it is necessary to pass a hand or foot past the left motion sensor, and when said sensor is triggered, the signal travels to the circuit board and this in turn sends a signal to the left solenoid valve to actuate, thereby allowing the water flow through the left supply duct to the left diaphragm; the left diaphragm is then inflated by water pressure to press the left counterweight fixed to the left rotating shaft, and to move it into the left chamber and rotating-lifting the lid connected by means of a bolt to said left rotating shaft to the open position.
  • the central presence sensor sends a signal to the electronic board to keep open both solenoid valves forcing the lid and seat to remain in the open position. Once the person leaves the place, the central presence sensor sends a signal to the electronic board so that this in turn sends the signal to both solenoid valves, closing the water supply and opening the way where the water discharge ducts are connected to the drain into the toilet tank or into the toilet itself by the main discharge duct. This action releases the diaphragm pressure and the lid or lid and seat are closed, as appropriate, by operation of gravity.
  • This closing action also happens if both the lid and the seat are in the open position and the person passes his hand or foot past the left sensor and said sensor sends a signal to the circuit board, which is turn activates left solenoid valve to release the pressure off of the left diaphragm and release the water into the toilet tank or into the toilet itself so as to lower the seat by gravity without the need to manually lower the lid.
  • the lid if the lid is in the open position, the user can pass the hand or foot past the right motion sensor, when the sensor is triggered the signal travels to the circuit board and this in turn sends a signal to the right solenoid valve, it is driven and allows water flow through the right duct to the right diaphragm.
  • said diaphragm is inflated forcing the right counterweight to move into the right device chamber and rotating-lifting the seat to the open position.
