Definitions
- the present invention relates to a vacuum cleaner and more particularly to a self-contained vacuum cleaner with high cleaning efficiency.
- Conventional vacuum cleaners generally include a frame mounted on transport members and carrying an electric turbine intended to create, through a filtering membrane, a vacuum in a particle collector. These particles are recovered from the ground, for example by means of at least one brush and are entrained towards the collector by air flow, via a transfer duct.
- these turbines use powerful motors (of the order of 1000 to 1500 W) which are supplied by the sector via electrical cords.
- the object of the present invention is to solve these technical problems satisfactorily by producing an autonomous and light vacuum cleaner with very high cleaning efficiency.
- a vacuum cleaner of the previous type characterized in that the turbine comprises a set of blades and a nozzle, the casing of which consists of an upstream volute portion centered on the axis of the blades and opening into a divergent downstream portion of said box communicating with the outside, and in that said diverging downstream portion is provided with longitudinal internal partitions to divide and slow down the air flow
- the wall of the box as well as the partitions are made with an acoustically insulating and / or vibration absorbing material.
- said divergent downstream portion communicates with the outside through lateral orifices provided on the wall of the casing of the nozzle.
- the upstream end of said duct is capable of being connected to a brush formed by a roller carrying an external peripheral brush and internal fins for driving the soil.
- said brush is rotated by an internal motor, the shaft of which is connected coaxially to the axis of rotation of said roller.
- said transfer duct consists of a flexible pipe removably connected to said brush.
- the upstream end of said pipe is provided with a rigid end-piece allowing both the sealed connection with a chute carried by said brush and the manual outlet for brushless suction.
- the flexible hose is, moreover, extensible.
- the transport members to be arranged in the lower part and, where appropriate, in the upper part of the frame.
- These organs are preferably made up of possibly driving wheels.
- said particle transfer conduit comprises an articulation delimiting a lower section and an upper section and allowing the opening of said conduit.
- said lower section of the transfer duct is provided with a housing for receiving heavy particles.
- said frame contains at least one rechargeable electric battery for supplying the turbine and / or motorizing the brush.
- the vacuum cleaner of the invention uses a new type of turbine with very high efficiency and low electrical power of the order of 80 W which can therefore be powered by rechargeable batteries.
- Figures 1A and 1B show sectional views in profile and front view respectively of a first embodiment of the vacuum cleaner of the invention
- Figures 2A, 2B and 2C show sectional and side views of a second embodiment of the vacuum cleaner of the invention respectively in three different positions of use.
- the vacuum cleaner shown in the figures comprises a frame mounted on transport members R and carrying an electric turbine T intended to create, through a filtering membrane M, a depression in a particle collector C.
- the turbine T is housed in a chamber and the collector C here consists of a flexible bag S with an air permeable wall, enclosed in a compartment K delimited upwards and laterally by a rigid waterproof wall and downwards by the membrane M ensuring the separation with the suction chamber k.
- a variant consists in joining the membrane and the wall of the bag S as shown in FIG. 2A.
- the bag S is wedged inside the compartment K by means of projections D secured to its internal wall.
- the particles are recovered from the ground and entrained towards the collector C by air flow via a transfer duct C.
- This air flow in the duct C is the result of the suction produced by the turbine T in the chamber k and compartment K.
- the frame is furthermore equipped with a grip and direction handle N.
- the turbine T comprises a set of blades P and a nozzle 1.
- the nozzle 1 consists of a box formed by 'an upstream portion 11 in volute centered on the axis of the blades and opening into a divergent downstream portion 12 communicating with the outside through orifices 10 formed laterally on the wall of the casing of the nozzle 1.
- the divergent downstream portion 12 is provided with longitudinal internal partitions 13 (FIG. 1B) making it possible to divide and slow down the flow of air discharged by the turbine T.
- the efficiency of such a turbine is thus very high (of the order 45%) due to the fact that, thanks to the partitions 13 and the increasing increase in the section of the downstream portion 12, there is no turbulence and that the flow at low speed therefore remains laminar.
- the desired effect is noticeable as soon as the angle ⁇ between the vertical and the tangent of the partitions exceeds 5 ° ( Figure 1B). It is possible to make the vacuum cleaner quieter by making the wall of the box as well as the partitions 13 with an acoustically insulating and / or vibration absorbing material.
- the turbine engine is powered by at least one rechargeable battery E housed in a casing A disposed under the turbine T inside the frame.
- the upstream end of the transfer duct C (in the direction of flow) is capable of being connected to a brush B making it possible to tear off and lift the particles to be vacuumed from the ground.
- the brush B is formed of a roller carrying an external peripheral brush b and internal fins a threshing.
- the brush B is mounted here in front of the lower rolling members R.
- the brush B is rotated either by an internal motor whose shaft is for example connected coaxially to the axis of rotation of the roller as in the embodiment of the Figures 1A, 1B, or by an external motor with a belt or gear transmission as in the embodiment of Figures 2A, 2B, 2C.
- the first mode has the advantage of being compact, more robust and less noisy.
- the transfer duct C is rigid and fixed on the frame and comprises a hinge-type joint H defining a lower section C1 slightly inclined and an upper section C2 which is substantially vertical.
- the articulation H allows the opening of the conduit as well as the access and or the emptying of a housing L for the heavy particles located at the base of the section C2, under the section C1.
- the transfer conduit C consists of a flexible flexible pipe connected in a removable manner to the brush B.
- the flexible pipe is, in addition, extendable by being produced, for example, in accordion.
- the upstream end of the conduit C is provided with a nozzle 2 allowing the sealed connection with a chute G carried by the brush B.
- the nozzle 2 also allows a manual grip to perform a brushless suction as shown in Figure 2B.
- the frame is provided with two sets of transport members R, R 'one of which is mounted in the upper part of the frame to allow the use of the canister vacuum cleaner as shown in Figure 2C.
- Each of the sets of respectively lower and upper transport members R, R ' preferably consists of a train of possibly driving wheels which is fixed to the frame by means of forks F, F'.
