Description

DUST VACUUM HOUSING

  The invention relates to a dust vacuum cleaner

  and more particularly its case. Such a housing

  generally carries two compartments separated by a partition having an air flow orifice, either a first compartment receiving a dust bag, or a second compartment receiving a suction unit, a self-winding cable, and various modules of In the vacuum cleaners of known type, the assembly of the suction unit, the cable winder and the various control modules is performed by successive operations which, therefore, are cost-effective. expensive. On the other hand, during the disassembly of said parts mentioned above to perform a repair or a control, the operations are long and difficult. The object of the invention is to remedy the above-mentioned drawbacks by using a housing

  Vacuum cleaner for easy, automatic and economical installation.

  According to the invention, the second compartment of the vacuum cleaner housing contains a box that encloses the suction unit and on which is mounted, furthermore, the cable self-winder and the various control modules and secured to said second compartment by

attachment means.

  Thanks to the box fitted to the vacuum cleaner housing, the coupling of the various parts to be inserted in said housing is achieved in a single operation, which, on the one hand, simplifies the manufacture and assembly, and, on the other hand, is of great economic interest. In addition, in order to dismantle one of the parts during a breakdown or during any other check, the operator, by an easy unlocking of the attachment means, can easily access the defective part. and win, as well, valuable time. The characteristics and advantages of the invention

  will emerge from the following description,

  taken by way of non-limiting example, with reference to the accompanying drawings, in which: FIG. 1 is a diagrammatic plan view of a vacuum cleaner housing equipped with a box according to the invention, FIG. is a perspective view of the box according to the invention, - Figure 3 is an exploded perspective view of the

  box of Figure 2 in which a module of

has been removed.

  According to FIG. 1, a dust extractor housing 1 comprises a first compartment 2 and a

  compartment 2. These compartments shall be

  equipped with a partition 4 having at least one airflow orifice 5 to allow the air to pass from the

  first compartment 2 to the second compartment 3.

  The first compartment 2 receives a bag of

  seat not shown comprising an opening which fits into a suction duct not shown, placed for example on a movable lid and in connection with a not shown suction tube. The second

  compartment 3 receives a suction unit 6, an automatic

  cable reel 7 and different control modules.

  According to the invention, the second compartment 3 contains a box 8 which encloses the suction unit 6 and on which is mounted, in addition, the cable self-winding 7 and the various control modules, said box 8 being secured of the second compartment 2 by

fastening means.

  The casing 8 illustrated in FIGS. 2 and 3 comprises two shells 9 and 10 which are assembled one to

  the other by locking means and one of which encloses the motor of the suction unit 6 carries the various control modules and the self-winding cable 10.

  The locking means consist, on the one hand, of hooks 11 arranged on the periphery of the

  9 of the shells and, on the other hand, elastic tabs 12 arranged on the periphery of the front part of the other shells and intended to be fixed on the hooks 11. In our

  example of embodiment, four brackets 11 and four pat-

  your elastics 12 have been arranged respectively on the shell 9 and on the shell 10, this number of hooks

  and elastic tabs being in no way limiting.

  The various control modules consist of electronic control modules comprising a first module 13 for varying the speed of the suction unit, a second module 14 for starting / stopping the suction unit and a third module 15 for electrical distribution. to be

  connected to electrical accessories of the vacuum cleaner.

  The casing 8 receiving the motor 16 of the suction unit 6 comprises electrical connections of the unrepresented automatic type connecting the electrical components 17 of the motor 16 to some of the different control modules. The electrical connections between the various different modules are not represented

in Figures 2 and 3.

  The box 8 thus formed is mounted and fixed inside the second compartment by the attachment means. Said fastening means are constituted on the one hand by screws 19, 20 shown in FIG. 1 which pass through holes 20 and 21 shown in FIGS. 2 and 3 and formed on the periphery of the casing 8 and which penetrate into bosses not shown and arranged on the bottom of the second compartment 3, and, secondly, by a collar 18 shown in Figure 1, placed on

  the shell 10 and fixed by screws 22, 23, shown in Figure 1 which penetrate into other not shown bosses and arranged on the bottom of the second compartment-3.

  To minimize the noise of the suction unit, the box is made of a plastic material, for example, polypropylene. In another embodiment, the material could be a sound-insulating plastic composite.

  The invention is not limited to the example of

  described. Many modifications including the nature and the number of parts that are integral with the box can be envisaged without departing from the invention.
