Definitions

  • a water and/or vacuum cleaner which includes a detachable upright collecting tank for water and larger particles providedwith a cyclone effect for separation of the water and the larger particles in the collecting tank and a dust filter located in the direction of flow before the motor unit for the cleaner.
  • vacuum cleaners cannot be used for drawing in dust and water at the same time. This has meant that by unawareness or carelessness, one has easily omitted the exchange the dust filter at the drawing in of water, and vice versa, which in the one case has resulted in a rapid clogging of the dust filter, which had to be replaced, and in the other case in damaging of the motors by the dust, which unavoidably had been drawn into them.
  • a further disadvantage of the known vacuum cleaners of this type is that they are very heavy to handle, because the motors are placed in the cover for the collecting tank, and which cover has to be lifted off every time the tank is to be emptied and the vacuum cleaner adapted to the drawing of water, and vice versa.
  • the water and/or vacuum cleaner according to the invention is substantially characterized in that the motor unit is located in the lower portion in a preferably mobile chassis, on which the collecting tank is placed and retained in place by a cover, from which extends a duct, which, via a duct mounted along the tank, directs the air flow from the tank interior to the suction side of the motor unit.
  • the cover By mounting the motor unit downwardly in the chassis, the cover can be of very light weight, which considerably facilitates the emptying of the collecting tank of the cleaner. This cover also can be made upwardly foldable.
  • FIG. 1 is a view in side elevation of the invention
  • FIG. 2 is a plan view
  • FIG. 3 is a view partly in elevation and partly in crosssection of the cleaner illustrated in FIG. 1, and
  • FIG. 4 is a fragmentary view partly in elevation and partly in cross-section of a valve arrangement modified in relation to the float actuated valve means illustrated in FIG. 3.
  • the water and/ or vacuum cleaner comprises a chassis 1, which, in the embodiment shown, is provided with wheels, a collecting tank 2 placed in the chassis, the tank being closed and retained in place by an upwardly foldable cover 3, and a filter container 4 disposed to the side of the tank 2 and provided with a cover 5 adapted to be clamped by clasps6.
  • the two covers are connected with one another by an arm 7, which, at its ends, is pivotally mounted to the cover 5 and cover 3, respectively, by hinge links 8.
  • the arm 7 further is provided with a locking member 9, which detachably connects the cover 3 with the arm 7 so that the cover 3 follows with the arm 7 when the arm 7 is being folded up about the link 8 mounted on the container lock 5.
  • the cover 5 also can be folded up, after the clasps 6 and the locking member 9 have been opened, so that the dust filter in the container 4 is accessible.
  • the Water and/ or vacuum cleaner is further provided with a handle 10 fastened to the container 4.
  • the cover 3 carries inlet socket 11, which is provided with a hose lock 12 and in a known manner is directed in a downwardly inclined manner to the tank wall, so that the incoming air is given a rotary motion in the tank, in order by a cyclone effect to separate the larger particles following with the air and the water in the tank 2.
  • the cover further includes a central sunk portion, which forms a seat 13 for a float actuated valve 14, and is provided with an opening 15 located centrally in the seat and facing toward the tank. This opening is surrounded by a cylindrical collar 16 extending to the tank.
  • an opening 17 in the lower surface of the arm Directly in front of the opening is located an opening 17 in the lower surface of the arm and which leads to a duct 18 arranged in the arm, which duct via a connecting piece 19 placed in the cover 5 to the filter container 4 opens into the filter container 4.
  • a dust filter 20 which may be of a cloth suitable for this purpose and shaped like a bag.
  • a paper filter bag of the throw-away type Into this bag may be inserted, for practical and hygienic purposes, a paper filter bag of the throw-away type.
  • the inner walls of the filter container are covered with a net work 21 of zigzag form for providing a gap between the filter bag and the container walls so that the entire filter area of the filter bag can be utilized.
  • the motor unit of the water and/or vacuum cleaner which may comprise several, preferably two to three electric fan motors 22, is, according to the invention, mounted downwardly in the chassis and encased. Upwardly to the tank the motor unit is covered by a disk 23 and downwardly by a disk 24, and the disks are retained in place by a bolt 25.
  • the lower disk 24 abuts tightly to a circular plate 26 and clamps it against the chassis.
  • the plate 26 is provided with holes 27 located directly in front of each motor 22, and the holes lead to space 28 formed by the disk 24 and plate 26, such space communicates through a duct 29 with the lower portion of the filter container.
  • 40 designates exhaust openings of the motor unit, and 41 the inlets for the cooling air, which is given off at 42.
  • the disk 43 which is clamped against the chassis by the disk 23, separates the inlets and outlets for the cooling air of the motors 22 by means of holes (not shown) provided for motor and by openings 44 provided in the inlet 41 of each cooling air duct.
  • the float actuated valve 14 shown in FIG. 3 is a valve disk 30 connected with a float 32 which depends into the tank.
  • the float may also be suspended on the cover 3 in the same manner as the float valve 39 shown in FIG. 4,
  • the spindle 31 is actuated by the float to move the valve disk 30 into closed position.
  • the valve disk is placed on distance members 34 for the valve seat.
  • the distance members 34 may also be placed on the valve 14.
  • the present cleaner can be provided with the valve arrangement shown in FIG. 4.
  • the cover 3 is provided with a centrally located relatively large opening 35 surrounded by a collar 36 extending to the interior of the tank and formed as a splash guard.
  • the collar may preferably be formed in one piece with the cover and in such a way that a groove or the like is formed about the opening 35 in the transition zone between the cover and the collar for suspending a substantially funnel-shaped body 38 formed as a seat for a foam-sensitive valve 37.
  • the through area A of the body below the valve seat is equal to or smaller than the through area of the valve 37 proper, depending on the weight of the foam-sensitive valve.
  • a vacuum cleaner a base member, an open-top tank supported by the base member, a suction fan unit supported by the base member, walls secured to the base member and defining a duct open at the top and being in communication with the suction fan unit, cover means for closing the top of the tank and the top of the duct, conduit means in the cover means connecting the tank to the duct, means defining a tangential inlet opening for admitting air carrying foreign matter and liquid into the tank for providing a heavy particle and liquid receptacle for receiving heavy particles of foreign matter and the liquid carried by the air entering the tank, means defining an outlet in said cover means and connecting the tank to the conduit means in the cover means, the outlet including a relatively large opening located centrally of the tank in the cover means, a cylindrical collar surrounding said opening, said collar being directed toward the interior of the tank and constituting a splash guard, the lower end of said collar being situated within the cover means, a substantially funnel-shaped body carried by and sealed to a portion of the cylindrical collar and said cover means and extending through
