Definitions

the present invention relates to the control of the discharge of water from the tank of a flushing system, for example a flushing system for sanitary fixtures and, in particular, a device which allows to stop the discharge of water, once initiated, even before the complete emptying of the flushing system tank.
Flushing systems are currently already known and widespread on the market, providing the possibility to adjust the amount of water that is needed to be used for the expulsion of the waste from the sanitary fixtures.
flushing systems of a known type envisage two activation buttons: a first button is intended to the complete emptying of the tank without the possibility of an intermediate stop, while a second button, generally alongside the first, activates the discharge after it has been pressed but stops it at the time of its release.
a flushing system for the discharge of water in a sanitary fixture of this type is described for example in French patent application n. FR-A-1194321 , wherein the flushing system comprises a tank, means for feeding a predetermined volume of water in the tank and a siphon housed inside the tank.
the siphon has a priming port obstructed by a movable shutter, a free extraction port, an upper bend arranged between said two ports and a discharge port.
the movable shutter is controlled by a rod between a priming port open position, in which the priming port is open to start the discharge of water from the tank, and a priming port closed position.
the depression condition that establishes in the siphon starts the water flow, by suction, also from the free extraction port; once the priming port is opened, also if the movable shutter returns to the closed position thereof, the water flow from the free extraction port continues until the complete emptying of the tank.
the object of the present invention is to propose a device which allows to control the discharge of water from the tank of a flushing system provided with a siphon and, in particular, to stop the discharge of water before the complete emptying of the tank.
Another object of the present invention is to propose a device of the type mentioned above which is structurally simple and easy to assemble even on flushing systems already installed.
a further object of the present invention is to propose a flushing system which provides, already in the production step, the possibility of controlling the discharge of water from the tank.
a device for controlling the discharge of water from the tank of a flushing system comprising a siphon housed in the tank and wherein the siphon has a priming port obstructed by a movable shutter, a free extraction port, at least one upper bend arranged between said two ports and a discharge port; the movable shutter is controlled by a rod between an opening position of the priming port, in which the priming port is open to start the discharge of water from the tank, and a closed position of the priming port.
the device according to the invention advantageously comprises an auxiliary valve actuated by the movable shutter between an open position, in which air is introduced at atmospheric pressure into the upper bend of the siphon, and a closed position in which the establishment of a depression condition is allowed in the upper bend of the siphon, at the time of discharge.
the device simply comprises a pipe mounted on the upper bend of the siphon to put in fluid communication the inner space of the siphon with the atmosphere.
the auxiliary valve intended to control the fluid communication between the siphon and the atmosphere comprises a stem axially sliding within the pipe.
One or more elements for guiding the sliding stem can be advantageously arranged in the pipe.
the pipe preferably comprises one or more through holes along its lateral wall to allow communication between the inside of the siphon and the outside atmosphere.
the device preferably comprises at least one element of rigid connection between the rod of the movable shutter and the stem of the auxiliary valve to move in an integral manner the auxiliary valve and the movable shutter.
the rigid connecting element can be made of any material, whether plastic or metal, provided that it retains the characteristics of rigidity of the connection. The choice of the material may however depend on various factors, for example the resistance to rust and corrosion, its weight or other considerations related to cost, ease of processing or the like.
the invention further relates to a flushing system for the discharge of water, comprising a tank, means for feeding a predetermined volume of water in the tank and a siphon housed in the tank; the siphon has a priming port obstructed by a movable shutter, a free extraction port, at least one upper rod arranged between said two ports and a discharge port.
the movable shutter is controlled by a rod between an open position of the priming port, in which the priming port is open to start the discharge of water from the tank, and a closed position of the priming port; and means to actuate the movement of the movable shutter between the two opening and closing positions of the priming port.
the flushing system is advantageously provided with a device for controlling the discharge of water from the tank which comprises an auxiliary valve actuated by the movable shutter between an open position, in which air is introduced at atmospheric pressure in the upper bend of the siphon, and a closed position in which the establishment of a depression condition is allowed in the upper bend of the siphon at the time of discharge.
the means for actuating the movement of the movable shutter comprise a pneumatic circuit comprising a pump actuatable by a button and a cylinder in which a piston slides bound to the movable shutter rod.
a process for controlling the discharge of a flushing system comprising a tank, means for feeding a predetermined volume of water in the tank and a siphon housed in the tank; the siphon has a priming port obstructed by a movable shutter, a free extraction port, at least one upper bend arranged between these two ports and a discharge port.
the movable shutter is controlled by a rod between an open position of the priming port, in which the priming port is open to start the discharge of water from the tank, and a closed position of the priming port; and means to actuate the movement of the movable shutter between the two positions.
the process comprises the steps of:
FIG. 1 Shown in Figure 1 is a flushing system comprising a tank 10 in which water is supplied through a valve 20 being controlled in a known manner by a float 25.
the valve 20 is adjusted so as to stop the incoming water flow from the water supply when the water reaches a maximum level LT to maintain a predetermined volume of water in the tank 10.
a siphon 30 which comprises a priming port 31 obstructed by a movable shutter 32, e.g. a half sphere shutter controlled by a rod 33.
the siphon 30 also comprises a free extraction port 34, arranged at the opposite end of the channel defined by the siphon with respect to the priming port 31, and a discharge port 35.
the siphon 30 is shaped so as to define at least one upper bend 36 between the priming port 31 and the free extraction port 34.
the means for actuating the movement of the movable shutter 32 include for example a pneumatic circuit 40 comprising a pump 41 actuatable by a button 42 and a cylinder 43 in which a piston 44 slides bound to the rod 33 of the movable shutter 32.
the flushing system advantageously comprises a device 50 for controlling the discharge of water from the tank 10 so as to be able to stop the water flow from the free extraction port 34 at the moment when the pressure is released on the button 42 of the pump 41 to actuate the movement of the movable shutter 32.
the device 50 shown in more detail in Figure 2 , comprises an auxiliary valve 51 actuated by the rod 33 of the movable shutter 32; the auxiliary valve 51 includes a stem 52 that is axially slidable within a pipe 60 represented in greater detail in Figure 3 .
a rigid linking member 55 connects the rod 33 of the movable shutter 32 with the stem 52 of the auxiliary valve 51 to move the auxiliary valve 51 and the movable shutter 32 in an integral manner.
the pipe 60 is mounted on the upper bend 36 of the siphon 30 and allows to put in fluid communication the inner space of the siphon 30 with the atmosphere. Through holes 61 along its side wall are in fact provided so that, when the valve 51 is in the position of Figure 2 , the atmospheric pressure can be ensured inside the siphon 30 and, more particularly, in the vicinity of the upper bend 36 of the siphon.
the pipe 60 comprises a threaded bottom end 62 which is screwed into a threaded hole 37 obtained in the siphon 30 and a threaded upper end 63 which receives a threaded plug 64, the latter preferably also provided with a guide element 65 for facilitating the sliding movement of the stem 52.
the rigid linking member 55 drags the stem 52 of the auxiliary valve 51 therewith by bringing this latter in closing position.
the siphon 30 is in a depression condition, generated by the water flow passing through the priming port 31, and is therefore permitted the intake of water also through the free extraction port 34.
Both water flows from the ports 31 and 34 thus reach the discharge port 35; in known flushing systems of this type, i.e. free from a control device 50, the water flow from the free extraction port 34 continues even if the pressure is released on the button 42, and therefore also when the movable shutter 32 returns to the closed condition of the priming port 31.
the water withdrawal from the tank 10 then only stops at the complete emptying of the tank 10, i.e. when the lower level of the water in the tank 10 reaches the level LB ( Figure 1 ) in which air at atmospheric pressure can enter again into the siphon 30 through the free extraction port 34.
the piston 44 descends again towards the lower position, such as that represented in Figures 1 and 4 , consequently dragging the movable shutter 32 in the closing condition of the priming port 31.
the auxiliary valve 51 whose stem 52 is rigidly connected to the rod 33, turns back in the open condition and restores the atmospheric pressure inside the siphon 30. Therefore, by re-establishing in the siphon the pressure condition equal to that of the external environment, the water flow through the free extraction port 34 is automatically stopped.
actuating means may also be made in the form of mechanical means, by way of suitable lever systems and/or joints, instead of the means represented here in the form of a pneumatic circuit 40.
