Definitions
- the invention relates to a vacuum cleaner dust comprising an engine block which contains a turbine powered by a motor and communicating with a vacuum chamber by an air passage formed in a wall of the engine block, a cover pivotally mounted on the engine block and delimiting with it the chamber of vacuum when said cover is in the closed position, an opening in said cover allowing the passage of air from the outside to the depression, a removable dust retention bag integral with a rigid plate in which is practiced an opening intended to be placed, in the position of operation, opposite the hood opening, slides formed in the cover and intended to cooperate with opposite edges of said rigid plate.
- the plate rigid and the slides are generally shaped to facilitate the placement and removal of the dust retention, given that a good device operation requires replacement regular bag.
- the main object of the invention is to remedy to this disadvantage, namely to make a vacuum cleaner dust of the aforementioned type, which ensures that the removable bag dust retention is properly placed before using the appliance.
- the wall of the engine block has at least one member, intended to cooperate with a stop rigid plate, so as to put the bag in its operating position when the cover is closed, in the event that he is insufficiently engaged in and keep it in position when the hood is closed.
- the invention also relates to a bag for a vacuum cleaner according to the invention, which comprises a body integral with a plate which has a stop intended for cooperate with at least one member of the wall of the engine block, said plate having a rectangular shape, said stop being formed by one of the edges of said plate, and the distance from said edge to the opening of the plate being substantially equal to the distance separating the cover opening member when the cover is in closed position.
- a vacuum cleaner dust 1 which comprises an engine block 2 forming a base mounted on rollers 17, so that it can be easily moved by the user.
- This engine block 2 contains a turbine powered by an electric motor, and whose function is to create a depression capable of generating a current suction air.
- the turbine communicates with the vacuum chamber 6 by a air passage 3 formed in the wall 4 of the base 2 which defines said chamber with the cover 5.
- An opening 7 made in the cover 5 allows the passage of air from the outside of the appliance towards the vacuum chamber 6, via a sleeve 19 intended to receive the end of a pipe - not shown -, for example a flexible, user-friendly duct.
- a removable dust retention bag 8, comprising a body 8 ′ secured to a rigid plate 9 in which an opening 10 is made, is placed opposite the opening 7 of the cover 5, the two openings 7 and 10, separated by the sleeve 19, in front coincide so that the air sucked in from outside the device is driven without losses towards the interior of the bag 8. So that the user can easily place the bag in its operating position, i.e. coincidence of the two openings 7 and 10, it is planned two slides 11 formed in the cover, intended for cooperate with the opposite edges 12 of the rigid plate 9. The bag is in its operating position when the user has pushed the rigid plate 9 into the slides 11, to its stop position.
- the body 8 'of the removable bag 8 consists of a superposition of several layers of material microporous, preferably paper, which leave pass air but stop particles of one dimension greater than a certain limit, of the order of a micron.
- the rigid plate 9 is preferably made in one rigid cardboard fixed to the body 8 'and having a shape substantially rectangular.
- the materials making up the superimposed layers are chosen with different porosities. Only the very small particles are allowed to pass into the vacuum chamber, so on the one hand, not to deteriorate the elements placed in the air circulation circuit, and on the other hand eliminate as much as possible the release of dust into the air ambient.
- the wall 4 of the engine block 2 which delimits with the cover 5 the vacuum chamber 6, has at least one member 13, for example projecting in direction of the interior of the room, intended for rely on a stop 23a of the rigid plate 9, so as to put the bag 8 in its position of operation when the cover 5 is closed, in the if he is insufficiently engaged in slides 11, and to hold it in position when the cover 5 is closed.
- Organ 13 is made up of parts plastic, formed during the molding operation of the wall 4 of the engine block, said wall 4 itself being in molded plastic and attached to the base 2.
- This body 13 is more precisely constituted by at least one of the holding pads for a particulate filter 16, placed in the air passage 3, said holding pads being located on the periphery of the air passage 3, and affecting the form of slots which have an external face 20, a upper surface 21 of support on the transverse edge of the rigid plate 9, and an internal face 22 of support and friction on the filter 16.
- This filter 16 performs a more selective retention of particles whose passage is authorized by bag 8, completing the chain of filtering of the intake air, before it passes through the turbine and its discharge into the ambient air.
- the removable bag 8 has a handle of gripping 15, intended to facilitate the positioning of the bag and its extraction by the user.
- the rigid plate 9 also presents in this area some more large width 23, so as to constitute on the one hand the full insertion stop for plate 9 in the slides 11, by its edges 23b, and on the other hand a coding which prevents the user from inserting the plate rigid 9 in the slides in the wrong direction.
- Figure 2a shows, while the cover is partially open, the rigid plate 9 of the bag insufficiently inserted in the slides 11, so that the opening 10 of the plate is not perfectly in view of the opening 7 of the cover 5.
- the bag as shown in the figures is made so that the plate 9 has a shape substantially rectangular, the stop 23a being formed by one of the edges of said plate, and that the distance L2 from said edge at the opening 10 of the plate 9 is substantially equal to the distance L1 between the bearing surface 21 of the member 13 and the opening 7 of the cover 5 when the latter is in closed position.
- the invention which has just been described concurs also reducing the size of such vacuum cleaner, which is a determining criterion in the design of household appliances.
