Definitions

  • the present invention relates to a toilet device and more particularly to a flush tank emptying device.
  • the mechanism traditionally used comprises a reservoir placed in height, connected to a bowl.
  • the tank is closed by a movable shutter in its lower part.
  • the shutter is removed and the liquid falls into the bowl.
  • the shutter closes off the orifice of the reservoir in order to stop the flow of the liquid. Examples of such toilets can be found in the documents EN 1188762 , EP 2045406 and FR 972728 .
  • this system requires the height positioning of the cistern, which does not allow the manufacture of compact systems.
  • wear of the stopper moving mechanism and wear of the stopper itself can be the cause of water leaks into the bowl.
  • an object of the present invention is to provide a compact toilet device which, moreover, is not subject to the problems of leaks which arise in known devices.
  • the invention relates to a toilet device according to claim 1.
  • the toilet device uses the suction generated by the Venturi effect to empty the flush tank into the bowl.
  • the invention thus makes it possible to propose a compact toilet device, the architecture of which does away with the use of gravity.
  • the device according to the invention avoids the leaks inherent in the devices of the prior art, since it does not include a shutter.
  • the large flush float can be held by a magnet linked to the manual trigger actuator controlling the pressurized water supply to the ejection means.
  • the invention advantageously uses the force exerted by the liquid contained in the cistern on the big flush float, to control the arrival of pressurized water in the ejection means.
  • the stem may have a washer which allows the big flush float to exert pressure on the stem to control the pressurized water supply to the ejection means.
  • the big flush float can slide on the rod between a position in which the float is magnetized to the magnet, and a position in which the float is in abutment against the washer and exerts pressure on the rod.
  • the small flush float can be fixed to the rod which controls the pressurized water supply to the ejection means.
  • the rod may have two washers which make it possible to control the pressurized water supply in the ejection means.
  • the Venturi tube may include a sleeve, inserted at the end of the connection to the pressurized water network, having a narrowing, and may include an opening capable of putting the flushing liquid in communication with the pressurized water circulating in the ejection means, to drive the flushing liquid into the column.
  • the pressurized water is accelerated and sees its pressure increase.
  • the pressurized water undergoes a sudden expansion which generates a suction phenomenon.
  • the column is also open to the tank. The liquid present in the reservoir is thus sucked up and entrained in the column.
  • the Venturi tube uses pressurized water circulation to suck the liquid present in the cistern.
  • the column may have a flared flange that can delimit, with the sleeve, the opening placing the flushing liquid in communication with the pressurized water.
  • At least three spacers can be assembled to said sleeve and can maintain the column.
  • the ejection means may comprise an ejection pipe forming a U, connected to a pressurized water network, comprising a descending part, an elbow, the Venturi tube and the column.
  • a pressurized water network comprising a descending part, an elbow, the Venturi tube and the column.
  • the tap connected to a pressurized water network and to the ejection means, it is possible to regulate the water supply to the ejection means.
  • the tap connected to a pressurized water network fills the tank with water.
  • the device according to the invention uses two separate taps to fill the cistern and to supply the ejection means.
  • the bowl may have a front part which may incorporate a cavity, and a rear part which may incorporate two side walls which may delimit a recess in which the flushing device is inserted.
  • the bottom of the flushing device can be positioned at an altitude less than or equal to the altitude of the bottom of the cavity of the bowl.
  • the use of suction linked to the Venturi effect to empty the cistern frees the device according to the invention from a height positioning of the flushing device.
  • the device according to the invention therefore makes it possible to position the flushing device at a free altitude relative to the bottom of the cavity of the bowl.
  • the positioning of the bottom of the flushing device at an altitude less than or equal to the altitude of the bottom of the cavity of the bowl emancipates the device according to the invention from the risks of leaks linked to the circulation of fluid by gravity which must necessarily be closed by a shutter and also allows the device according to the invention to be compact.
  • the liquid present in the cistern is at the same altitude as the bowl.
  • the flushing device can be entirely included in the rear part of the bowl, between the two side walls, the seat surface of the bowl and the lower surface of said bowl.
  • the flushing device is fully incorporated into the bowl.
  • the device according to the invention is then compact and without risk of leaks caused by the use of a stopper.
  • a mechanical actuator can be adapted to trigger the closing of the pressurized water valve.
  • the mechanical actuator may include at least one magnet and at least one supernatant float in the liquid contained in the flush tank. Said at least one magnet and said at least one float can be adapted to trigger the closing of the pressurized water tap.
  • the present invention relates to a toilet device 1 visible on the figure 1 .
  • the toilet device 1 comprises a suspended bowl 10 and a tank 101.
  • the bowl 10 comprises a seat surface 18, a flat surface 12 forming the bottom, two side walls 19 and a rear vertical part 13 which can be fixed to a wall.
  • the seat surface 18 is positioned substantially parallel to the ground.
  • the bowl 10 further comprises a cavity 11 intended to receive liquids and a weir 16 intended to discharge the water driven into the bowl in order to clean it.
  • the bowl 10 comprises a recess 15 intended to accommodate a flushing device 100
  • the hunting device 100 which can be seen on the figures 2 to 4 , notably comprises a tank 101.
  • the bottom of said tank 101 is at an altitude similar to or lower than the altitude of the bottom of the cavity 11 of the bowl 10.
  • the upper part of the tank 101 can be substantially at the same altitude as the seating surface 18 of the bowl 10
  • the tank 101 can be made of polymer suitable for storing a liquid and can be integrated into the rear part 13 of the bowl 10, between the two side walls 19.
  • a pressurized water drain valve 120 is fixed in the upper part of the tank 101.
  • the valve 120 supplies an ejection pipe 110.
  • the ejection pipe 110 has a U-shaped geometry and consists of a tubular part descending 111, a bent tubular part 112 and a rising tubular column 114.
  • an ejection elbow 115 is positioned at the exit of the rising part 114.
  • a Venturi tube 130 is positioned between the elbow portion 112 and the column 114 of the pipe 110.
  • the Venturi tube 130 comprises on the one hand, a sleeve of tubular section 131, having a section similar to the section of the bent part 112, a conical narrowing of section 132 opening into the column 114.
  • four fins 133 are fixed to the sleeve 131.
  • the column 114 rests on the four fins 133 so as to present a cylindrical opening 134 in the ejection pipe 110.
  • the flushing valve 120 is controlled by a mechanical actuator 125 controlled by a full-flush manual actuator and a small-flush manual actuator.
  • the mechanical actuator 125 may include a small flush float 128 fixed on a descending rod 126, and a large flush float 127 sliding on the column 114 and the rod 126.
  • the large flush float 127 and the small flush float 128 can be made of expanded polystyrene or any other material having a lower density than the density of water.
  • Rod 126 has three pressure washers 126A, 126B and 126C.
  • a lever 121 is positioned between washers 126A and 126B. Lever 121 controls drain valve 120.
  • the 126C washer is located near the large hunting float 127.
  • the big flush float 127 is linked to a magnet 129 which is positioned on a wall of the bent part 112.
  • the flushing device 100 comprises a filling valve 140.
  • the filling valve 140 allows the filling of the reservoir 101 after a flushing operation.
  • the filling valve 140 is connected to a pressurized water network.
  • a three-way valve 180 connects the taps 120 and 140 to a pressurized water network.
  • this three-way valve 180 makes it possible to successively supply the emptying valve 120 during the emptying of the flushing tank 101, then to supply the filling valve 140 in order to fill the tank 101.
  • a filling float 141 installed sliding on a column 142 actuates the closure of the filling valve 140.
  • the operation of the toilet device 1 according to the invention is as follows
  • the small flush float 128, immersed in the flushing liquid then exerts pressure on the rod 126 which holds the washer 126B against the lever 121.
  • the big flush float 127 By being separated from the magnet 129, the big flush float 127, immersed in the flushing liquid, exerts a thrust on the washer 126C of the rod 126.
  • the rod 126 is moved and the washer 126B presses on the lever 121 which opens and keeps open the drain valve 120.
  • the narrowing of section 132 creates a local acceleration of the fluid.
  • the water thus accelerated undergoes a sudden expansion which generates a suction of the surrounding liquid.
  • the opening 134 allows the fluid present in the tank 101 to enter the column 114. In this way, during the passage of the pressurized water, the suction generated by the Venturi tube 130 draws the fluid present in the tank 101 , in column 114.
  • the fluid thus sucked into the column 114 is then evacuated, through the elbow 115 and the weir 16, into the cavity 11 of the bowl 10.
  • the elbow 115 guarantees the correct orientation of the liquid flow during its evacuation into the cavity 11 of the bowl 10.
  • the drain valve 120 is connected to the running water network and supplies the ejection pipe 110.
  • the water from the drain valve 120 is at a pressure substantially equal to three bars.
  • the filling valve 140 is open until the filling float 141 actuates the closure of said filling valve 140.
  • the toilet device according to the invention therefore offers the advantage of being able to position the tank behind or under the bowl. It is thus possible to obtain a compact toilet device.
  • the configuration of the flushing device makes it possible to avoid liquid leaks into the bowl.
