  • a suction box a suction box
  • a motorized suction turbine pneumatically connected to the outlet port of the box
  • at least one duct one end of which opens into the box.
  • Such a structure is used in centralized suction installations, on movable vacuum cleaners, of the canister or canister type, in mechanical ventilation installations but also on certain so-called dry or smoke extraction columns.
  • centralized suction installations but it is obvious that the invention applies to any installation comprising at least one duct, one of the ends of which is connected to a suction assembly or ventilation.
  • the suction assembly is arranged with its dust container in a technical room and the conduit opening into the box forms part of a network of conduits connecting the central unit to suction sockets arranged in the areas to be cleaned.
  • Each suction outlet is closed by an articulated cover and can receive the rear end of a hose, the front end of which is provided with a handle and is capable of receiving a rigid tubular extension or suction members.
  • the central unit is put into operation and stopped by micro-contacts arranged on each outlet and by a low-voltage electrical network connecting each outlet to the central vacuum unit.
  • the introduction by the user of the rear end of the suction hose into one of the sockets triggers the power supply to the electric motor of the central vacuum unit, while the withdrawal of this end causes the interruption of this diet.
  • the documents US-A-3,669,145 and GB-A-2,015,652 each describe a centralized suction device comprising a main suction turbine and a system providing a secondary vacuum during the non-operation of the turbine.
  • the opening of a connection flap for a suction hose on the installation modifies the value of the vacuum, which provides pneumatic information causing the main suction turbine to operate.
  • Document EP-A-0 156 011 relates to a device for controlling a canister vacuum cleaner, in particular by actuation from the holding handle of the dust suction hose.
  • This device comprises a small duct parallel to the dust suction hose used to convey a pneumatic pressure wave from the handle to the suction group, which causes the turbine to operate when it is stopped, or when it stops.
  • vacuum waves sent into the small duct, from the handle make it possible to regulate the suction rate. Given its complexity, such a control device is not applicable to a central vacuum or ventilation installation.
  • the object of the present invention is to remedy these drawbacks by providing a remote control device, for switching on and off, for a suction or ventilation installation, a device which, simplifying the fitting of the conduits and the structure of the hose, is simple, reliable inexpensive and safe for the user.

  • the forms of execution shown with reference to FIGS. 1 to 11 all use, as control means for starting up a pneumatic pressure wave generated in the handle 8, and for stopping, a variation in the suction flow rate, all both captured near the central vacuum unit 1.
  • this pressure wave is produced by a piston 13 formed at the rear end of the end piece 9 slidably mounted in the handle body 14. More precisely, this piston is formed by a flap 15 articulated at 16 on the rear end of the end piece 9.
  • the pressure wave does not dilute in the box 2 and can be perfectly detected by a sensitive pressure switch 20, connected by a conduit 22 to the end 6a of the conduit 6.

  • the pressure wave created at the handle is perceived at the terminal end of the network of conduits 6 and detected by the pressure switch 20 which controls, through the housing 23, the supply of the electric motor 3.
  • the turbine 4 creates, in the box 2, a depression which has the effect of raising the flap 18, as shown in dashed lines in Figure 1, but also the flap 15 disposed in the handle 8, which therefore allows the installation to operate normally.

  • This butterfly is controlled from the outside of the handle by a button, not shown. The closure of this butterfly cuts the suction flow and therefore leads to an increase in the vacuum in the box 2. As will be explained below, this increase in vacuum is detected by appropriate means which react on the control unit. 23 to interrupt the supply of the motor 3.
  • the means for detecting the vacuum in the box 2 are associated with a timer authorizing the opening of the electrical supply circuit of the motor 3 only after a certain time.

  • the end piece 9 is locked in rotation relative to the body 14, for example by a finger 28 sliding in a groove 29 of the body and is provided with at least one screen 30 ensuring its locking in the stopped position by cooperating with elastic means.
  • these means consist of a ball 32 arranged with its spring 31 in a housing 34 of the body handle.
  • the blocking provided by the notching forces him to exert a greater force on the end piece 9.
  • the nozzle 9 is moved abruptly in the direction of the arrow 17 and thus allows the plug 26, constituting the piston, to expel the air in the tubular body 14 then, by the connector 14a, in the flexible pipe 7.
  • the opening 27 coincides with the outlet of the connector 14a in the body 14 and thus allows the connection of the nozzle 9 with the suction flow rate coming from the hose 7.
  • FIG. 6 and 7 differs from that of Figures 3 and 4 in that the flap 15, articulated at 16 at the rear end of the nozzle 9, is secured to a substantially radial finger 15a, suitable for the end of the stop travel and the end of the start travel to come into contact with abutment faces, respectively 35 and 36 of the body 14.
  • the finger 15a meets the stop 35 and forces the flap to pivot in the direction of obturation of the rear end of the end piece 9, while at the end of the start-up stroke, the stop 36 forces this finger to pivot, in the opposite direction, to bring the flap 15 into the open position, completely freeing the rear end of the end piece 9, in anticipation of the arrival of the suction flow.
  • the handle 8 is composed of a front end 9a with an articulated flap 15, a rear body 14b connected to the hose 7 and a central portion 37 in the form of a bellows and made of less rigid material than those constituting these two other parts.
  • the displacement of the end piece 9a in the direction of the rear part 14b of the handle results in the deformation of the bellows 37, and causes a pressure wave reacting on the control means 23, arranged in the control unit.
  • suction 1 As in the embodiment described with reference to FIG. 1, as soon as the hose is traversed by a suction flow, the flap 15 lifts itself by allowing this vacuum to pass through the nozzle 9a and allow the suction.
  • the handle 8 is monolithic, and has an anterior portion 14c, closed by an articulated flap 38, and a rear portion 14d. This communicates, on the one hand, with the hose 7, and on the other hand, near the part 14c, with the outlet orifice 39 of a turbine 40 with autonomous supply and with start-up control. by button 41 disposed on the handle.
  • the central unit is started up by controlling the rotation of the turbine 40, for a time sufficient to generate, in the part 14d of the handle, a pressure wave.
  • the vacuum causes the flap 38 to be lifted which, in this particular case, closes the outlet port 39 of the turbine 40 to avoid fouling of the turbine by dust.
  • the turbine is replaced by a bulb, a bellows or other equivalent means which, under manual pressure, sends a pneumatic pressure wave into the handle.
  • the embodiment shown in Figure 10 differs from that shown in Figures 3 and 4 by the shape of the means ensuring the blocking of the piston 13 in the stopped position.
