Abstract
The invention discloses a control device for an integrated suction cleaner unit (1) pneumatically connected to a system of tubes (13) which open, at their ends (13A), onto couplings (11) into which the mating end (9) of a hose (8) is inserted, the latter having at its other end (8A) a handle (5) onto which are fitted the cleaning accessories. The control device for the suction cleaning unit is of the type using acoustic transmission via the tube system (13) located between the suction cleaning unit (1) and the couplings (11) pressure wave detection (19, 23 and 28) for detecting specific acoustic pressure waves and controlling the suction cleaning unit (1). The positive pressure wave detection occurs when an acoustic pressure wave is generated when the hose (8) is connected to one of the suction cleaning couplings (11), and produces after handling, a specific acoustic wave conveyed by the tube system (13) to the detecting microphone (19) and pressure wave detection unit (23 and 28) controlling the suction cleaning unit (1). A negative pressure detection unit comprises a negative pressure switch (21), in the form of a tube (27) containing an orifice (20), a moveable core (26), and a compression spring (24), which detects negative pressure in the tube system (13), and controls the suction cleaning unit (1).
