Definitions
- the present invention relates to vacuum cleaners and more particularly to tank vacuum cleaners and carpet washers, capable of sucking water from a damp or wet floor.
- the engine is located under the tank, which lowers the center of gravity of the assembly, and the tank is removable.
- the tank is mentioned to be removable only for repair operations.
- the tank removed leaves free access to the engine.
- parts protruding under the tank penetrate deeply into the base of the device and require a lot of lifting before releasing it, which makes this removal impractical.
- US patent 5560075 constitutes an improvement of this type of very stable device because having the motor in the lower part.
- the safety device obstructing the suction, when the water level in the retention tank exceeds a fixed limit, consists of a float which rises in an open housing towards a suction mouth facing downwards . The air and water sucked up then make a U-turn in a downward vertical pipe to go towards the turbine, which can then advantageously be in the axis of the downpipe.
- the retention tank can be removable but its volume is unbalanced by the empty volume corresponding to the space left for the turbine engine block, and the release of the tank cannot be done conveniently from the side where the motor is positioned.
- the object of the invention below is a powerful, economical, very stable vacuum cleaner which can vacuum dry or in a humid environment and where handling is facilitated.
- the object of the invention is achieved by a vacuum cleaner according to claim 1.
- the upper face of the base includes another element for centering the retention tank constituted by a turret shape of low height, centered on the motor-impeller assembly in the axis of which the air outlet opens. of the retention tank.
- the water which accidentally arrives on the base could not penetrate the engine, having to go up the edges of this turret.
- the turret is of a diameter equal to or greater than that of the motor-impeller assembly.
- the base contains a dust cassette where final filtration of the air is carried out before it is discharged to the outside, a cassette to which it is planned to connect an air blowing pipe.
- the base includes a cord winder and a housing for the power outlet.
- It can also include a water pump enabling the vacuum cleaner to be equipped with a water spraying or soil washing function.
- the base comprises the control members accessible from above for foot control on the upper face near the rollers.
- Foot control is thus facilitated while preserving stability.
- the tank has a suction chimney which has two vertical conduits connected laterally in the upper part.
- a first conduit encloses a float in a lower part equipped with a suction grid, an air intake mouth facing downwards capable of being closed by the float separating the lower part of the upper part.
- the other duct evacuates the air at the bottom of the tank in the center of a turret shape corresponding to that of the base.
- the two ducts are closed upwards so that the air circulates from the first duct to the other duct. In one version, this closure is ensured by the tank cover which fits over the chimney, thus avoiding a specific closure part.
- the float In the event that the water sucked in with the air and settling in the tank reaches a maximum level, the float would approach the air intake mouth in the form of a valve seat and be sucked in, which would close the air circuit. to prevent water from entering the impeller.
- the bottom of the tank is of the same shape as the corresponding imprint in the base which allows easy installation of the tank on the base and the centering on the turret is obtained without effort.
- FIG. 2 is a schematic view in longitudinal section of the device.
- FIG. 3 is a top perspective view of the device, the tank being separated from the base.
- FIG. 4 is a front view of the device, the tank being separated from the base.
- FIG. 5 is a schematic view in longitudinal section of another version of the device.
- FIG. 6 is a schematic view in longitudinal section of a variant of the previous version of the device.
- the vacuum cleaner includes a tank 1 closed by a cover 2 and provided with a folding handle 3 whose axis of rotation 4 intersects the vertical passing through the center of gravity of the tank.
- the construction of the tank 1 substantially parallelepipedic with a substantially flat bottom is such that the progressive filling of the tank with water does not substantially change the vertical of the center of gravity, and the handle 3 supports the tank 1 in a way very balanced regardless of this water level.
- the device is essentially composed of two parts: a tank 1 and a base 5.
- the tank 1 is placed on the upper face of the closed base 5 having an imprint 6 (Figure 2) whose hollow shape is that of the bottom of the tank 1.
- Lateral quick fixing systems 7 (FIG. 1) make it possible to secure the tank 1 on the base 5.
- the base 5 has rollers 8 at the front and wheels 9 at the rear for its movement.
- the foot controls 10 of the device are located on the front edge of the base 5 in the upper part. Of low height, they do not hinder the release of the tank 1.
- the foot control effort is directed naturally in a substantially vertical manner.
- the controls 10 are three pushers 10a, 10b 10c respectively exerting an action on a cord winder, on the starting and stopping of the the appliance, and on the electric control of a washing pump.
- These commands can be located, as a variant, on the sides of the base in order to completely free the upper surface of the base.
- the base 5 also includes supports 11 and 42 allowing inter alia the storage of the suction pipes and cleaning accessories such as, for example, nozzles of different shape and stacking.
- the tank 1 is provided with a suction chimney which has two vertical conduits connected laterally in the upper part.
- a first conduit 12 encloses a float 13 in a lower part 14 equipped with a suction grid 15, a suction mouth 16 facing downwards capable of being closed by the float 13 separating the lower part 14 from the upper part.
- a second duct 17 evacuates the air at the bottom of the tank 1 in the center of a turret shape 18 corresponding to the turret shape of the top of the base 5.
- a circular rib 19 located under the tank 1 and centered on the turret shape 18 rests on a seal 20 housed in a groove of the turret shape of the base 5.
- the cover 2 of the tank 1 fits with its ribs 31 on the chimney thus closing the conduits 12,17 in the upper part without additional specific part.
- the upper part of the conduits 12,17 is closed by a cup 32 of suitable shape, which makes it possible to reduce the precision of the molded parts and facilitates sealing.
- the motor-impeller group 21 centered on the turret 18 is equipped with a volute 22, the air outlet of which is directed into a removable cassette 23 where a filter 24 provides ultimate filtration.
- the cassette has an air exhaust port 25 which can be provided to receive the end piece of a flexible air blowing pipe.
- the electrical supply cord 26 of the device is wound up in the base 5 on a reel 27 and the power outlet is housed in a compartment 28.
- the base 5 can also receive a water pump 29 intended to pump in a known manner clean water from a compartment 33 of the tank 1 and propel it towards the suction nozzle for washing the soil or spraying it for any other use.
- a conduit therefore leads the clean water or the detergent, from the compartment 33 to the pump 29, by an internal conduit along the tank, a tight connection 43, slightly deep in the base, ensuring the removability of the tank , while keeping the base relatively flat, with only slightly protruding part, the quick fasteners 7 and the supports 11.
- the compartment 33 placed at the top of the tank serves as a cover as shown in FIG. 6, which allows saving of material and easy access without opening the casing both for filling the compartment through the orifice 34 and at the tank 1 proper.
- the moist air sucked in arrives in the tank 1 through the flexible suction pipe 30, connected to the opening 39 formed in the tank.
- the water is deposited in the tank 1 with the dust and the float 13 accompanies the level.
- the air enters through the grid 15 in the lower part 14 of the conduit 12 bypassing the float 13. It then passes into the mouth 16 and joins the conduit 17 through which it enters the impeller motor group 21.
- the seal between the tank 1 and the base 5 is produced by the gasket 20.
- This orifice is designed to optionally receive a blowing pipe.
- the float When the water level in the tank 1 is sufficiently high, the float approaches the mouth 16 where it is sucked. The float then closes the air circuit like a valve ensuring the protection of the engine against water.
- the user unhooks the suction tube 30, the quick fasteners 7 and using the handle slightly lifts the tank out of the cavity 6 as well as the socket on the turret 18.
- the tank is then completely released from its base 5 and easily transported in a balanced manner. It remains to lift the cover 2 and empty the contents of the tank, or, without removing the cover 2, empty the tank through the opening 39 of the tank left by the withdrawal of the suction tube.
- the tank relatively symmetrical, hence its balance, can be placed on the ground, small feet 51 to ensure its stability while protecting the end of the clean water pipe, when present. These feet also facilitate the replacement of the tank on the base having recesses provided for this purpose.
- the base therefore remains substantially flat, with no significant prominence.
- the cassette 23 is removable and can easily be emptied of its dust by simple shaking.
- the replacement of the tank 1 on the base 5 is just as easy. Thanks to the imprint 6 and the turret 18, it centers itself and it is enough to press lightly to apply the fast fixing system to the closure.
- the chimney being integrated into the tank does not interfere with the handling during the emptying and repositioning phases. Furthermore, this construction allows tanks of different heights to be fixed on the same base and a range of devices to be easily derived.
- a range of dry suction apparatus by replacing, as shown in FIG. 7, the tank with a waste receptacle, comprising either a dust suction bag 38, such as as presented, and contained in an envelope 35 in two pieces 36 and 37 so as to allow the replacement of this bag, or a waste separation device of inertial or cyclonic type.
- a waste receptacle comprising either a dust suction bag 38, such as as presented, and contained in an envelope 35 in two pieces 36 and 37 so as to allow the replacement of this bag, or a waste separation device of inertial or cyclonic type.
- tank used in this document is therefore to be taken in the broad sense and includes water tanks, but also waste receptacles as described above.
- the device does not have an integrated reel, the compartment 28 then being used for providing the user with an electrical outlet enabling him to connect another device such as a drill, a electric saw, ...
- the electrical supply wire of the device then passes through an orifice 48 in the base 5. It can be wound around the tank for its storage.
- the present invention is notably remarkable by the centralization of the technical functions of the tank type vacuum cleaner in a relatively collected base and whose face intended to receive the tank is substantially flat.
- This base constitutes a real technical unit grouping, around the motor and its impeller, different functions, which can be combined, including:
- the tank centering elements represented essentially by the bowl imprint 6 completed by the low-profile turret shape around the engine, - a water pump and its connections to the clean water tank and to the flexible hose d 'injection, - the speed controller,
- These organs may include motors, sensors, electronic control cards, batteries, as well as the various displacement or displacement assistance organs.
- This versatile technical unit allows, by the many functions that can be installed, without affecting the storage tank, to produce different ranges of products at a lower cost, by combining the different functions present on the base, these different ranges of products can be enlarged by tanks of different heights, and therefore of different volumes.
