Definitions
- the flexible wall is generally arranged vertically on a reinforcement having a
- REPLACEMENT SHEET When cleaning or replacing the flexible wall, it is shaken to make the most of the particles and dust fall into the recovery tank.
- the bin is mounted mobile in a compartment from which it is removed to evacuate its contents.
- Dust-laden air is introduced into the compartment and, to avoid too great a pressure drop, this compartment is closed by means of a door which is pressed against a frame with the interposition of a seal.
- GB-A-865 262 which describes a vacuum cleaner comprising a container containing a dust bag and a cover which surmounts the container / bag assembly inside which a filter wall is disposed.
- This filtering wall is held in shape by a complex frame to be stretched. Between the cover and the top of the tank is arranged a seal which can be supported by the cover or by the tank.
- Pivoting hooks on articulated parts secured to the tank cooperate with holes made in the cover in order to close the vacuum cleaner and to keep the tank against the seal.
- this vacuum cleaner does not have any means to ensure a good seal between this filter, the dust bin and the compartment containing this bin, which causes significant pressure drops which considerably reduce the yield.
- Patent CH-A-409,266 which describes an industrial vacuum cleaner comprising in its lower part a dust bin equivalent to a dustbin. This dust bin is mounted movable from bottom to top by a plate associated with a bracket. The upper part of the vacuum cleaner includes a filter held on a complex frame, completely independent of the tank.
- This receptacle is mounted movable from bottom to top by complex mechanical means which do not ensure correct and direct sealing between the filter and the receptacle.
- the filter is subjected to metallic reinforcements so that it undergoes significant stresses and that it wears out.
- This device comprises a seal between a fixed intermediate part and a removable lower part, a seal which undergoes the mechanical stresses resulting from the positioning and removal of the receptacle. This results in a decrease in the tightness and therefore in the performance of the device by pressure drop.
- This tank is secured by a complex mechanical assembly of parts articulated at the top when the device is in the operating position.
- US-A-4,222,753 which describes a cleaning device comprising a tank without air inlet surmounted by a part which includes a filter.
- This filter is held at its base by a metal part associated with a spring which exerts a radial force, which accentuates the mechanical forces supported by the filter and therefore its wear or even its tear.
- the lower part consists of a container containing a bag which does not prevent the accidental fall of dust between it and the container and there is no tight mechanical connection with the filter.
- this device has no means ensuring the seal between the tank and the part which overcomes it and, therefore, the device can not provide satisfactory performance performance.
- the present invention overcomes all these drawbacks by providing a new structure for the input of the device which guarantees maximum efficiency for the device by eliminating the causes of leaks and pressure drop.
- this device allows:
- the bag 2 and the border 3 can also form an inseparable whole, for example by directly overmolding the seal 5 on the mouth of the bag 2.
- the seal 5 is made of synthetic material whose rigidity is chosen to allow both to give a stable shape at the mouth of the bag and provide flexible deformation to form a seal.
- sets 1 are stored and replaced one by one as needed, the sets 1 saturated or worn being eliminated altogether.
- the bag 2 comprises, as is known per se, three pockets 6, 7 and 8 which tapering from a common quadragular mouth 9 to an individual vertex 10, 11 and 12.
- a device comprises an enclosure 20 mounted on casters 21 and closed at its upper part by a plate 22 supporting the various desired mechanical organs, including an electric motor 23 supplied with current by a cable 24 and a turbine 25 driven by the motor 23 by means of a belt 26.
- the turbine is associated with a conduit 27 placed opposite a passage formed in the plate 22 and opening into a chamber 30 provided with hooks 31 for hanging the assembly 1 by its loops 13.
- the chamber 30 has a window 32 on the front which, in normal service, is closed by a removable waterproof plate (not shown).
- Angles 33 are fixed inside the walls of the chamber 30 to constitute a peripheral stop at the edge 3.
- the assembly put in place, determines a lower compartment 40 in which a tray 41 is mounted movably in the manner of a drawer, which is why it has an operating handle 42.
- the container 41 has a continuous flat edge 43 whose width corresponds substantially to that of the seal 5 of the edge 3.
- the tank 41 On its two opposite side walls, the tank 41 has two ramps 44 and 45 located at two different levels each a little lower than stops 46 and 47 placed inside the compartment 40.
- Each stop 46 and 47 is constituted by a roller mounted pivoting in order to avoid friction when they are put into action as will be described later.
- Holes 48 pass through the side walls of the tank 41, holes which are located opposite passages 28 and 29 formed through the walls of the enclosure 20.
- the compartment 40 has no bottom in order to avoid any accidental accumulation of dust during handling of saturated assemblies 1, after removal of the container 41. But to facilitate the movements of the latter, longitudinal slides 50 are provided ( Figures 3 and 4) including a central on which rests a roller 51 mounted pivotally front of tray 41.
- the compartment 40 has no bottom but simple angles, the dust which falls, after removal of the container 41, when changing the bag, soil the soil, which may not be too important, for example when the device is located in a garage which must necessarily be cleaned in a particularly vigorous manner.
- REPLACEMENT SHEET remove it to empty it before installing the new clean set 1.
- the drawer is, for example, provided with buttons 61 for its operation.
- the operation of the device which has just been described is as follows:
- An assembly 1 is placed in the chamber 30 by introducing it from bottom to top, through the compartment 40, after removal of the container 41.
- the closure plate (not shown) is removed which normally closes the window 32
- the loops 13 are hooked to the hooks 31 and it is ensured that the edge 3 is well pressed against the angles 33, then the closure plate is replaced on the window 32.
- the tank 41 is introduced into the compartment 40 by rolling its roller 51 on the central slide 50.
- a suction duct 70 either to the orifice 48, or to the orifice 49 after installation of the tank 41, using the passage 28 or the passage 29.
- a tape 71 is placed fixed by bolts 72 on the orifice 48 which has not been chosen but the unused passage 28 or 29 can remain open without drawback since it is outside of tank 41.
- the passage used, moreover, n 'itself has no tight connection with the conduit 70 which is directly connected to the orifice of the tank 41.
- a leak-free junction is thus produced from a suction nozzle 73 of any known type fixed at the end of the duct 70 to the inside of the bag 2, through the inside of the tank 41.
- the cable is connected power supply 24 and the motor 23 is started, either by direct action on a switch, or by using a mechanism triggered by a token, a card or a coin.
- the device can then be used in a manner well known per se.
- the turbine 25 sucks in the air and thus creates a vacuum at the mouth of the nozzle 73.
- the air loaded with dust and impurities travels through the duct 70, arrives in the tank 41 and rises in the three pockets 6, 7 and 8 of the bag 2 which thus provide a very large surface for the passage of air and the retention of dust and impurities.
- REPLACEMENT SHEET impurities attached to the bag 2 in the tray 41 It can be seen that here these dusts and impurities cannot soil anything because they can only fall into the tray 41, tightly connected to the bag 2 by the edge 3.
- the line 70 is disconnected, the tank 41 is removed and emptied and the bag 2 is removed by the compartment 40 after having unhooked the loops 13. No fixing does not hinder or slow down this operation since the bag 2 and the border 3 are simultaneously removed.
- the border 3 may not include a rigid frame 4, this being only an aid in the establishment and maintenance of the seal 5.
- the connector 74 used for joining the conduit 70 to the tank 41 can be of any known type and its production is within the reach of those skilled in the art, so that it is unnecessary to give a complete description.
