Abstract
Abstract It consists of various dust containers (1) without connection among them and provided with one or more covers (2) which in their interior design perform the function of collector, there existing an air inlet (3) via at least one of the containers, which are joined forming the aforementioned air outlet collector in the interior of the cover or covers (2) and in a single air outlet towards the motor. At the inlet of at least one of the containers there is a projection in the shape of a half-dome (20) which distributes the air in such a way that, depending on the shape and dimension of that projection, the containers (1) can be filled at the same time or the air flow is distributed among them in such a way that the air enters into the containers (1) in the direction perpendicular to the covers (2), with the corresponding flow defining a T-shape when it arrives at them.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
162 words
A vacuum cleaner comprising a plurality of dust containers
(1) without connection among them and provided with one or more
covers (2) which in their interior design perform an outlet
collector function, there existing an air inlet (3) via at
least one of the containers which are joined forming the said
air outlet collector in the interior of the cover or covers (2)
and in a single air outlet towards the motor, characterised in
that : at the inlet of at least one of the containers, there is
a projection in a half-dome shape (20) which distributes the
air: for enabling the containers (1) to be filled at the same
time or the air flow to be distributed among the containers (1)
depending on the shape and dimension of said projection; and
for the air to enter the containers (1) in a direction
perpendicular to the covers (2), with a corresponding flow
defining a T-shape when it arrives at the covers (2).
Claim 2
Dependent Claim
33 words
A vacuum cleaner according to claim 1, characterised in
that the connection of the said dust containers (1) is carried
out in a horizontal plane with respect to the T-shaped air
inlet direction.
Claim 3
Dependent Claim
55 words
A vacuum cleaner according to claim 1, characterised in
that the said containers (1) receive the air via a duct (7)
which passes approximately through the centre of the plurality
of containers, and when passage through the collector ends,
the latter exits towards the motor via another tube located in
the centre of the containers.
Claim 4
Dependent Claim
27 words
A vacuum cleaner according to claim 3, characterised in
that the final sections of the said duct (7) are straight,
having a minimum length of 50 mm.
Claim 5
Dependent Claim
51 words
A vacuum cleaner according to claim 1, characterised in
that a handle (5) of the vacuum cleaner has two buttons (8)
located at a certain distance from the handle which have to be
pressed for releasing the container from the casing of the
vacuum cleaner by means of side flanges (9).
Claim 6
Dependent Claim
71 words
A vacuum cleaner according to claim 1, characterised in
that the cover/s (2) of said containers is/are located in the
proximity of the handle (10) of the vacuum cleaner; the lock of
the dust container being located in said cover and said lock
being close to the handle of the container; said cover/s (2),
in their interior design, acting as a distribution collector
for the air from containers towards the motor.
Claim 7
Dependent Claim
40 words
A vacuum cleaner according to claim 1, characterised in
that the place of the container where the lock (11) of the said
cover/s fits has a wall (12) which protects the said lock (11),
preventing it from being accidentally actuated.
Claim 8
Dependent Claim
30 words
A vacuum cleaner according to claim 1, characterised in
that the air inlet and outlet ducts of the container form an
integral part with a handle (19) of the container.
Claim 9
Dependent Claim
41 words
A vacuum cleaner according to claim 1, characterised in
that the hose which reaches the container is fitted in a tube
(13) of at least 50 mm in length , which permits the said hose
to be housed in its interior.
Claim 10
Dependent Claim
39 words
A vacuum cleaner according to claim 9, characterised in
that the said tube (13) has a side opening (18) at one end
which facilitates the guiding of the hose in its location in
the casing of the vacuum cleaner.
Claim 11
Dependent Claim
35 words
A vacuum cleaner according to claim 2, characterised in
that the connection (4) between said hose and the container is
integrated into the hose itself, forming an assembly
dismountable and removable from the vacuum cleaner.
Claim 12
Dependent Claim
18 words
A vacuum cleaner according to claim 11, characterised in
that the said assembly includes a sealing joint (14).
Claim 13
Dependent Claim
31 words
A vacuum cleaner according to claim 6, characterised in
that the said handle of the vacuum cleaner has a U-shaped
recess (15) where one or more extension tubes (16) are housed.
Claim 14
Dependent Claim
31 words
A vacuum cleaner according to claim 1, characterised in
that it comprises a transmission pulley (17) with a larger
diameter not coinciding with the centre of symmetry of said
transmission pulley.
Claim 15
Dependent Claim
37 words
A vacuum cleaner according to claim 1, characterised in
that the said transmission pulley (17) has a profile in which
the radii of curvature on both sides of the shaft passing
through the larger diameter are different.
Claim 16
Dependent Claim
22 words
A vacuum cleaner according to claim 1, characterised in
that there exists an independent air inlet duct (3) for each
container (1).
