Definitions
- the present invention relates to the technical field of the use and the putting into service of devices for evacuation by flushing effect.
- the invention relates to flushing tanks suitable for cleaning the water closet bowls.
- the evacuation devices comprise a reservoir provided, at the base, with a hole communicating with a flushing conduit opening into the bowl.
- a tank is also provided with a water supply conduit, the passage section of which is controlled by a tap automatically controlled in opening and closing by a level sensor.
- the equipment of such a tank is completed by a valve plug adapted to control the communication hole between the tank and the flushing conduit.
- a plug is associated with opening and closing control means, generally with manual actuation.
- the large quantity of water implies a relatively long time to fill the tank, which is also a generator of noise transmitted by conduction, if the means for controlling the water supply are not technically advanced.
- the valve plugs, traditionally used, are simple and inexpensive to build and are frequently the cause of leaks which further increase water consumption.
- the principle of operation consists in admitting water into the bell, which has the effect of causing the elastic extension of the membrane and of putting under pressure the stored water, in particular as a result of the compression of the trapped air. between the bell and the casing.
- the illustrated embodiment shows a complex and specific structure which appears incompatible with the current form of hunting tanks.
- the second lesson of this application consists in replacing the membrane with a bladder of substantially cylindrical shape which constitutes the reservoir proper in relation to the supply duct.
- This bladder is placed inside a compression casing which gives it its maximum form of elastic development under water pressure. It is, it seems, expected, by such an achievement, that the reaction to the elastic deformation of the bladder comes add to the weight of the stored water to evacuate it under pressure.
- the object of the invention is to propose new structural means making it possible to further reduce the quantity of useful or used water for each service of an evacuation tank, such means being designed to allow the manufacture of a functional unit independent of that of the tanks.
- the object of the invention is also to offer a possibility of standard or universal manufacturing allowing mounting or adaptation of such devices in drainage tanks of traditional designs, standardized or not.
- Another object of the invention is to propose new structural means allowing the production of a simple, robust and reliable functional unit which can be produced at an attractive cost price.
- the evacuation device by flushing effect according to the invention is characterized in that the capacity is produced in the form of a closed pocket, flattened, comprising two substantially parallel walls and comprising: - a resistant environment,
- Fig. 1 is a sectional elevation of a device adapted inside an evacuation tank.
- Fig. 2 is a cross section taken substantially along line II-II of FIG. 1.
- Fig. 3 is a view, comparable to FIG. 2, but illustrating the device in another characteristic operating position.
- Fig. 4 is a sectional elevation of an alternative embodiment of the device according to FIG. 1.
- Fig. 5 is a schematic view showing a development for a specific application.
- Fig. 6 is a schematic sectional elevation illustrating an alternative embodiment of some of the constituent elements of the invention.
- Fig. 7 is a schematic view showing another alternative embodiment.
- the flushing device according to the invention is intended to be incorporated in a tank 1 designed to be adapted, by any suitable means, for example on the rear shelf _A of a water bowl -closet or the like, in a preferred but not exclusive application of the invention.
- the tank 1, which can be closed by a removable cover 2 has a bottom 3 having a hole 4 intended to be connected to a flushing conduit 5 opening, for example, inside a bowl not shown of a water closet or the like.
- the communication to the flushing duct 5 is controlled by a shutter 6 either automatic or controlled and, for example, by a valve plug which has any of the known traditional conformations.
- the drain 6 can be arranged inside or outside the tank 1 which, ordinarily, is connected to a water supply duct 7, the passage section of which can be controlled, upstream of the tank 1, by an isolation valve not shown.
- the evacuation device is formed by a pocket 10 of generally flattened shape having two substantially parallel walls and which may include a plane of symmetry JP of planar or curved character.
- the pocket is arranged in the reservoir 1 so that the plane _P_ is oriented vertically, for example, substantially in alignment with the vertical and longitudinal plane of symmetry of such a reservoir, when the latter is constituted, as this is traditional, in the form of a generally parallelepiped volume.
- the pocket 10 could also be placed in a tank of different shape or in a tank whose large plane of symmetry would be arranged horizontally or otherwise.
- the pocket 10 is formed to delimit a closed, sealed, variable-volume capacity 11, which is mounted in the tank 1 by means 12 of adaptation and reaction described below.
- the bag 10 comprises at least one thick, elastically deformable part, intended to be placed under elastic stress in the filled state of the bag, as shown in the following.
- the thick, elastically deformable part preferably consists of at least one of the two substantially parallel walls 10a, 10b_ constituting the pocket 10.
- the two walls thick 10a, 10b are joined at their periphery by any suitable means to form a kind of resistant frame or surround 13 which can be associated or constitute by itself the means 12.
- the material of La or walls 10a, 10b is chosen to maintain characteristics of flexibility at the temperatures of use, as well as a resistance to a possible aggressive character of the liquid medium, such as water used to produce the flushing effect.
- the frame or the peripheral surround 13 may result from the connection of the walls 10a, 10_b and / or from the presence of a reinforcing frame or else of a fixing plate.
- the pocket 10 is adapted in the tank 1 by the means 12 which may, for example, consist only of a suspension section 14 corresponding to the upper part of the surround 13.
- the section 14 may include end portions 15 provided with means 16 adaptable on the upper part of the reservoir 1.
- the means 12 can also be completed by the lower part 17 of the surround 13, which forms a base or a connection and direct or indirect fixing plate on the hole 4.
- the pocket 10 is mounted in relation to the hole 4 to communicate with the flushing conduit 5.
- the plate 17 can be connected to the hole 4 by sealed intercommunication means which can be considered usual in the subject area. It can be any removable fixing means comprising seals whose relative tightening is ensured by means of nuts or the like.
- the connection between the plate 17 and the hole 4 can be established directly and, in such a case, the valve plug 6 can then be disposed at the outlet of the tank 1 in the flushing conduit 5 and upstream of the connection with the bowl. . It can also be provided to arrange the valve plug 6 inside the tank, as is given by way of example in FIG. 1.
- the plate 17 has a hole 20 crossed by the end piece 21 of a seat 22 made integral with the plate 17 during the manufacturing being or not inserted.
- a nut 23 or the like tightens a seal 24.
- the end piece 21 can be provided to ensure mounting on a connection tube 25 mounted, by a collar ring, such as 26, directly or indirectly on or in the bottom hole 4.
- the mounting of the pocket 10 in the tank could also be ensured by the means 12 consisting only of an adaptation between the bottom 3 and the plate 17, in particular by the tube 25, that the valve plug 6 is disposed internally or not in La poche 10.
- the seat 22 is, for example, surmounted by a chimney 27 provided with a lumen 28 and containing a ball or a ball 29 Free or slaved to an elastic member tending to push it in abutment against the orifice of the seat 22 In this state, the ball or the ball 29 isolates the internal volume or the capacity 11 of the connection tube 25 leading to the flushing duct 5.
- the ball 29 is associated with a control member 30 comprising, for example, a finger 31 extending inside the tube 25 to control, by pivoting on a joint 32, the lifting of the ball 29 relative to the seat 22
- the finger 31 can be extended outside the tube 25 by a control lever 33 linked to any actuation means, manual or not, accessible outside the reservoir 1, to be controlled, in the usual and traditional way, especially as is the case in the application to a water closet bowl.
- the bag 10 is connected to the water supply conduit 7 by a tube 35 of flexible or rigid nature, which may include a non-return valve of known design, intended to prevent any return of the water contained under pressure in the bag. towards the circuit.
- the tube 35 opens into the pocket 10 in any suitable manner, either in the upper part, or in the lower part, or even in the middle part.
- the deformable part such as 1 ⁇ of the pocket is used to control the admission into said pocket of water under pressure supplied by line 7.
- This control can for example result from a pressure balancing between the admitted water and the elastic resistance offered by •
- the deformable part, such as 10a in its deformed state defining the volume or the maximum admitted capacity of the bag.
- This control can also take place by providing on the tube 35, in its part 35 extending inside the tank 1 and parallel to one of the walls 10a or 10b, a control means 36 constituted by a chapel mounted, by a rigid and resistant sole 37, on the internal face of the corresponding wall of the reservoir 1.
- the chapel 36 defines a hole 38 which can be closed or opened by a shutter 39, for example of the ball or valve type, which is linked directly by a tail 40 to the corresponding elastically deformable wall of the pocket 10, that is to say 1 ⁇ £ in this case.
- the tail 40 and the shutter 39 are shaped so that, in the flattened and empty state of the pocket 10, the port 38 is open, so as to establish free communication between the conduit 7 and the pocket 10.
- the pocket 10 In the stable state of rest, the pocket 10 is flattened by the memory of shape and embodiment which has been conferred on it during manufacture.
- the capacity 11 defines the minimum tight volume with respect to the tank 1.
- the pressurized water, distributed or brought by the supply duct 7, can therefore freely enter the capacity 11, fill the latter and cause the deformation of one or both walls 10a and 10b which, under the action of the supply pressure, undergo elastic deformation under stress leading to local stretching resulting in inflating the bag 10, as given as as an approximate example in fig. 3.
- Such a state of maximum filling and stretching corresponds to the introduction of the maximum quantity of pressurized water constraining the walls 10a_ and 10b to a high elastic deformation stress due to the thickness which they have.
- the filling can stop automatically, When a balance is established between the network supply pressure and the elastic deformation constraint imposed on the walls 10_ and 10b_ or result from the deformation of the wall 10a_ pushing the shutter 39 in the closed position of the port 38, then closing any communication between the pocket 10 and the conduit 7, as illustrated in FIG. 3.
- the bag is then in the state of filling under load, favorable for commissioning.
- the control lever 33 is moved, for example, in the direction of the arrow f-, (fig. 1), so that the finger 31 lifts the ball 29, in order to establish communication between the window 28 and the tube 25.
- the control lever 33 is moved, for example, in the direction of the arrow f-, (fig. 1), so that the finger 31 lifts the ball 29, in order to establish communication between the window 28 and the tube 25.
- the water contained in the pocket 10 is forced, by gravity load effect but also by high pressure resulting from the reaction to the elastic deformation imposed on the walls 10a_ and 10b restoring the work stored, through the light 28, the seat 22 and The tube 25 and maintains the bi Lie or the ball 29 in the high position.
- FIG. 4 shows a development aimed at offering the possibility of further reducing the quantity used for a service when it is judged that a less important hunting action may take place.
- the bung 6 is constituted by a shutter, of the type with controlled valve 29 .., which is connected by a rod 31., to the control member 30 permanently urged in the closed position by a timed reactive pusher 130, for example fitted on the bottom 3.
- the body 30 is provided with a rod actuator 131 externally forming the reservoir 1 a button or the like 132 déplaçabl e inside of a window 133.
- the link 131 is doubled by a bar 134 which forms a button 135 located in the window 133 parallel to the button 132 by covering the latter by a tab 136.
- the bar 134 has a displacement stroke limited by a stop 137 carried by the reservoir 1.
- the button 132 By acting on the button 132, the maximum amplitude of the movement is imparted to the member 30 for maximum opening of the bung 6 for a period controlled by the return push-button 130. On the contrary, by acting on the button 135, a opening amplitude limited by the stop 137 is given to the bung 6 for a period Limited by the elastic return push-button which brings the shutter 29 .. more quickly back to the closed position.
- Fig. 5 shows that it may also be advantageous to have the pocket 10, for example flat on the bottom 3 of the reservoir 1, by means of the means 12 constituted by a plate 17 which can also then form the second non-deformable wall of the pocket 10.
- the stretching of the elastically deformable part, such as 10a makes it possible to control, in particular by a rod 43, a level sensor 44 closing a tap controlling the conduit 7.
- the rod 43 can be guided by any suitable means, in particular by the top 41 of an envelope or of a casing constituting the device as shown.
- the rod 43 can also be used to control a rack or the like 45 generating the drive of an axis or a shaft 46 capable of causing the rotary movement of a rotating bezel through a disinfection unit -cleaning-drying, as exists in particular for collective equipment water closets.
- a rack or the like 45 generating the drive of an axis or a shaft 46 capable of causing the rotary movement of a rotating bezel through a disinfection unit -cleaning-drying, as exists in particular for collective equipment water closets.
- Fig. 6 shows an alternative embodiment in which the valve plug 6 is arranged outside the tank 1 and, for example, at the flushing duct 5.
- the valve plug 6 is formed in the form of a system 50 two bistable valves 51 and 52, one constituting the shutter of - the bung 6 and the other a valve or a shutter disposed on the conduit 7, upstream or in replacement of the control means 36.
- the system 50 is completed by an actuating link 53 comprising a lever pivotally mounted on an axis 54 and connected, on either side of the latter, on the one hand, to the shutter 51 and, on the other hand , to the shutter 52.
- the actuating link 53 ′ is also linked by a link 55, disposed between the pivot axis 54 and for example the shutter 51, to a control member with elastic return 56 of the pedal type. or controller.
- the supply duct 7 is open, while the plug 6 is closed.
- the bag 10 can thus be filled with water.
- the user presses on the pedal 56 to command a reverse conjugate movement of the shutters 51 and 52, in order to open the plug 6 and, simultaneously, to close the duct 7.
- Fig. 7 shows, schematically, such a variant in which the system 50 is designed so that in the resting state the bistable valve 51 is open, while the bistable valve 52 is closed. The bag 10 is then not filled before being put into service.
- the actuating link 53 is extended to be articulated to a rod 60 Linked, for example, to the level sensor 44 which is placed on the path of the rod 43 secured to one of the deformable walls, such as 10a, and guided through the top 41.
- the pedal 56 When the device should be put into service, the pedal 56 is actuated to move the system 50 to the reverse position in which the valve 51 is closed, while the valve 52 is open. Pressurized water is admitted into the pocket 10, the wall 10a_ of which is stretched up to the maximum filling limit. In this state, the rod 43 actuates the sensor 44 which acts on the rod or the like 60 to bring the system back
- the means according to the invention consist of a pocket of small dimensions defining a relatively limited capacity, in the state of rest in a flattened form, allowing placement 'interior of any tank 1 specifically built to receive such a device or, again, resulting from a traditional manufacture.
- the adaptation can be easily carried out by means of the support and suspension means 12, as well as adaptation means, such as the tube 25 or the like.
- the object of the invention therefore makes it possible to ensure the equipment of any tank and, more particularly, of those of water closet bowls in order to limit, never before, the consumption of water for each service, while ensuring a maximum and effective hunting effect proven by official tests carried out.
- Another advantage of the invention lies in the fact that the small capacity of the bag 10 makes it possible to reduce the filling time significantly and therefore offers a faster commissioning possibility.
- An additional advantage of the object of the invention relates to the great simplicity and robustness of the pocket 10 which can thus provide a reliable service of long duration. Furthermore, the whole of the invention represents a low-cost device requiring only a reduced investment for its manufacture.
- the invention also makes it possible, because of the small size and the possible implantation according to variable orientations of the pocket, to produce reservoirs of new shape.
- the deformable part 10a is used to control the supply duct.
- this control could also be entrusted to an independent body, such as a timer.
- Fig. 1 shows that, as a safety measure, an overflow means 65 can be adapted to ensure the evacuation of the water in the event of the bag 10 leaking.
- the object of the invention finds a particularly interesting application in flushing tanks of water closets.
