  • the control device comprises on the one hand the means of interrupting the suction flow using a quarter-turn valve constituted by a fitting placed in seconds between the handle and the hose, and secondly, near the suction group, means to detect the absence of flow with an increase in depression and connected pneumatically to the network of conduits and electrically to a sensor itself connected to the control logic which, after a certain time, will control the electrical relay of the motor to stop the suction unit.
  • the same control logic authorize the restarting of the suction unit controlled by the manipulation of the flexible, only after the turbine has come to a complete standstill.
  • the above means to detect the absence of flow with an increase in depression in the network of conduits are constituted by a tubular-shaped depressostat with an orifice its base and inside a core screwed on a bolt, itself supported on a spring compression. It also includes a sensor electrically connected to the control unit and able to detect in the tube at the height of a second orifice, the absence or the presence of said nucleus.
  • the pressure switch used is adjustable to adapt to the maximum vacuum possible in the pneumatic network of conduits in order to tolerate any non-repairable leak arising from improper installation.
  • the above means to detect the absence of flow with an increase in depression in the network of conduits are formed by the microphone making it possible to detect in said network the sound wave produced by the manipulation of the hose.
  • the microphone is also able to detect the difference in noise level caused in the ductwork by an increase in vacuum, so as to output a second signal to the control unit which will stop the group, after a predetermined time delay.
  • the adjustable pressure switch with its sensor, the pressure wave detector microphone acoustic and / or increased depression in the network as well as the logic of order are put together in a single container so they can bind pneumatically very easily using a tee connecting to the above network of It is important to note that the control unit can also manage a source of current from the suction unit generally intended to be connected to the sockets this source available via a connector outside the group facilitates the installation of the system because a simple electrical connection with two conductors enough.
  • the suction unit referenced 1 As shown in the drawing in Figure 1, the suction unit referenced 1 as a whole and of the most widespread type by design on the market, is equipped with a motor 49 controlled by a relay 41 to rotate a turbine 48 in order to create a depression in a box 16 and, via a orifice 17 made in said box, throughout the pneumatic network of ducts 13.
  • conduits 13 are at their ends 13A connected to suction outlets 11, distributed in the cleaning zone, each being equipped a shutter 10 sealing the network 13 when closed.
  • a flexible and light hose 8 fitted with a nozzle 9 connects to one of the sockets 11 after opening the shutter 10.
  • a handle 5 At the other end of the hose 8 is a handle 5 which can, at its end 5A, receive cleaning accessories.
  • this installation is advantageously equipped with a remote control device ensuring the starting or stopping of the group suction 1 shown in 2 for its receiving part and in 3 and 8, for its sending part.
  • the compact receiver 2 is housed in a tee 14 for its pneumatic connection with network 13 and connect to connector 36 by the conductors 34 and 35, for its connection to the electrical part 37 of the suction group 1.
  • the suction group 1 route takes place after introduction of hose 8 with its end piece 9 in the intake 11 after opening the shutter 10.
  • the fact of manipulating the flexible 8 is enough to produce a sound wave on a specific frequency which by traversing the network of conduits 13 arrives at a sensor 19 of the microphone type which transmits the signal, via its conductors 22, to all of the electronic components defining a control logic 23.
  • the control unit 23 controls a current source 28 of so as to cause a current draw in the circuit constituted by all of the conductors 50, 51, 34, 35, 39, 40 and 42 interconnected by means of connectors 33 and 36, so that the coil of the relay 41 of the suction group 1 establishes, using its contact of power, a current flow in conductors 45, 43 and 47 representing the phase of a mains supply at 220 volts, the neutral being connected directly to the motor 49 by conductors 44 and 46.
  • the electric motor 49 of the turbine 48 starts then on to create a depression in the box 16 then, passing through the orifice 17, in the entire network of conduits 13.
  • the current source 28 supplying the control logic 23 comes advantageously of the low voltage transformer 38 supplying the relay 41. It should be noted that the control logic 23 uses a very current source for its operation weak or even insignificant, this one being able to cross the coil of relay 41 without harming its smooth running
  • the suction unit 1 is stopped on the one hand, with means making it possible to interrupt the flow of air in the suction network 13, and on the other hand with means making it possible to detect this absence of air flow in the network.
  • the means for interrupting the air flow in the network 13 are constituted by a valve 3 formed in a connector connected with its sleeve 3B to the end 8A of the flexible 8 and with its sleeve 3A at the end 5B of the handle 5.

  • the means making it possible to detect the absence of air flow with increased vacuum in the ductwork 13 may consist of a pressure switch 21, which, associated with a sensor 32 connected to the control logic 23, is constituted by a tube 27 with an orifice 20 at its base and at inside a core 30 screwed onto a bolt 26 bearing on a compression spring 24.
  • the increase in depression in the duct network 13 is transmitted to the pressure switch 21, through the orifice 20 in the tube 27 causing the displacement of the core 30 in the direction of arrow 29 which compresses, using the depression adjustment bolt 26, the spring 24.
  • This displacement of the core 30 is to release an orifice 31 formed on the height of the tube 27 thus allowing said electronic sensor 32 disposed opposite, to detect the absence of the core 30 at this height and transmit, via its conductors 25, a signal to the control logic 23 which will command the source 28, after a period of time preset, cancellation of current flow in the circuit formed by the conductors 50, 51, 34, 35, 39, 40 and 42, which are interconnected by connectors 33 and 36.
  • the time delay preset in control unit 23 for stopping group 1 has for object of avoiding any untimely stoppage of said group, due to the temporary obstruction of cleaning accessories during normal use.
  • the coil of the control relay 41 actuates its contact power towards the opening causing the interruption of the current flow in the circuit constituted by the conductors 45, 43 and 47 of the motor 49 of the turbine 48 which, no longer being powered by phase but only by neutral using conductors 46 and 44, stops to work.
  • the core 30 of the pressure switch 21 rises in the opposite direction to that of arrow 29 obstructing the orifice 31 of the tube 27 at the height of the sensor 32 which then transmits, via its conductors 25, a new signal to the control logic 23 to give, after a certain time delay (corresponding to the end of the complete shutdown of the turbine (48), the possibility of sensor-microphone 19 to listen to a new signal to restart the suction group 1.
  • the absence of flow with an increase in the vacuum in the duct network 13 can be detected by the sensor-microphone 19 which measures the difference in the sound level produced at inside the network of conduits 13 by the variations in depression.
