Abstract
Description
- For many years, centralized vacuum cleaner systems have been preferred, whereas possible, to traditional vacuum cleaners, that is those noisy household appliances which, dragged along the house, put again into circulation the air, which is suctioned and not thoroughly filtered.
- It is known that such centralized vacuum cleaner systems use a control unit, connected to the suction intakes, which are suitably distributed over the building to serve, by means of a plastic canalization, chased or in view. By temporarily connecting to the said intakes suitable accessories, which are similar to those used with the traditional vacuum cleaners, the dust and rubbish are conveyed, through the said canalization, into the suitable container connected to the control unit, which is provided with a filtering device to separate the air from whatever is dragged therewith.
- The said control unit, being particularly large, is generally arranged in a service room, or outside in a sheltered location, also because of the noise, that, even though is moderate, proves to be anyway annoying inside a dwelling-house.
- The aim of the present invention is to provide a control unit for vacuum cleaner systems, which is more practical than the control units currently used, in terms of reduction of overall dimensions, of simplicity and reversibility of the installation, and of comfort of use. A further aim of the invention is to effectively reduce the noise, without using bulky and anaesthetic silencer means, arranged outside the control unit.
- The innovative characteristics of the said control unit are described below, and are illustrated by way of non-limiting example in five drawings, wherein:
-
FIG. 1 is a side view of the control unit according to the invention; -
FIG. 2 is a sectional vertical view, designated with the reference XX inFIG. 1 ; -
FIG. 3 is an axonometric exploded view of the control unit according toFIG. 1 and FIG. 2 ; -
FIG 4 and 5 are respectively a front view and a lateral view of the control unit, during the operative phase of removing the dust container, after unlocking the hooking means of the said container to the superposed central stage; -
FIG. 6 and 7, and FIG. 8 and 9 are front view and vertical sectional view of the two reciprocally hookable elements, as illustrated inFIG. 10 , designed to maintain the dust container in a closed position. -
FIG. 11, 12 and 13 are respectively a lateral view and two vertical sectional views of the control unit, provided with the self-cleaning unit of the filter. - It is clear from the accompanying drawings, especially from
FIG. 1, 2 , and3 , that the control unit according to the invention comprises a central body orstage 4, provided with aninput duct 500 of the suctioned air. Thestage 4 is closed on the upper side by a sort of lid orhead stage 9, which bears anoutput duct 901 of the filtered air and acontrol panel 903, which serves as user interface. Thestage 4 is provided on the lower side with acontainer 1, for collecting the dust, which is equipped with a sort offunnel 104, designed for fastening a suitable bag to collect the dust. Thefunnel 104 is rimmed by awasher 105, pressed between thecontainer 1 below, and the superposedcentral stage 4. - The said
container 1 is provided with a rapid hooking and releasing means to thecentral stage 4, in order to be easily removed and inserted through simple frontal movements by a single operator, manually and without making use of tools. To this aim, as can be seen inFIG. 4 and 5 , ashackle 3, nearly semicircular-shaped, is hinged on itsseats 301, externally of thecentral stage 4 on therespective seats 401, so that by pushing a release button 102 (FIG. 6, 7, 8, 9, and 10 ), steadily arranged on thedust container 1 in a suitablefrontal seat 101 and clasping from below with a hooked portion 103 asuitable protrusion 302 of theshackle 3, the release of the saidprotrusion 302 allows thecontainer 1 to remain hung under theshackle 3. Theshackle 3 is arranged tilted, by turning upon thepivots cylindrical protrusions 300, which engagerespective notches 100, suitably realized on the outer surface of thecontainer 1. Thus hung, thecontainer 1 can be seized with both hands and easily removed to replace the dust bag, that is, besides, provided with a suitable tensioning means. - The control unit according to the invention allows to limit the noise, thanks to the fact that the motor unit -
fan wheel 7 is not tighten with screw means to thecentral stage 4, as in the usual control units, but it is simply locked, being interposed between a couple of vibration-proof rubber gaskets gasket 701, that is the upper one, shaped to be locked by matching suitable notches of themotor 7, is reversible, in order to fit two sizes of the motor. The size of the motor, being definitely small, give the control unit a compact design and small overall dimensions. - Yet the achievement of a low noise level is assured, especially thanks to a
silencer 8 which is arranged, inside thehead stage 9, by means of a plurality of notches, realized on its base, matching respective protrusions realized on thegasket 701. The air coming from themotor 7 below is forced to pass inside thesilencer 8, which is labyrinth-shaped and completely covered with sound absorbent material, for example foam polyurethane. The air goes through a convoluted course inside the silencer, then it comes out directly into theoutput duct 901. The silencer is characterized in that its input and output ducts do not directly face each other, in order to perform the aimed reduction of the noise intensity. - In the illustrated embodiment, the said
silencer 8 comprises acontainer 800, preferably made of ABS and realized by injection moulding, which is closed by alid 840 and it bears, stuck on its inside, abase 810, a sort of labyrinth-shaped duct 820 and a closing element made of sound absorbent material. Twoopenings container 800, and are suitable to be arranged respectively by the input and the output of the air. - A further feature of the claimed control unit is that it can fit different conditions of the system to serve, being preset so that it allows to choose under way the side from which the suctioned air enters and the side from which the filtered air exits, independently one from each other.
- In particular, the input of the suctioned air takes place, at the
central stage 4, through aduct 500, which protrudes from an end of anelement 5, which is fixed by screw means to the said central stage in correspondence with two suitable openings 402 (fig. 12 ), arranged symmetrically with respect to the vertical median plane of the central unit. Theelement 5 is perfectly reversible, because it allows to obtain the input of the air from eachopenings 402, by simply arranging it with itsduct 500 matching the chosen opening. - Concerning the output of the filtered air, the
head stage 9 can be adapted to allow the exit from one or from the other side, by inverting the position of twolateral bulkheads output duct 901, to be arranged by theoutput 802 of thesilencer 8, suitably rotated for this purpose when it is fixed inside thehead stage 9. - The control unit is fixed to the wall, by pre-assembling a
suitable support 6 onto the wall, and then applying the control unit to the support by way of a simple frontal push, and by the fastening ofsuitable protrusions 501, projecting from theelement 5 from the opposite side with respect to the side to be fixed to thecentral stage 4. Theprotrusions 501 are fastened into respective holds 601 realized on thesupport 6, and they can be released simply by pushing twolateral tabs 602. - Advantageously, the said frontal fastening system allows positioning the control unit in a small place, or even in a built-in box, because it does not require any lateral or vertical movements, to mount or to remove the control unit.
- The
air filter 200 inside the control unit can be easily installed and removed since it is supported by aring 201, screwed on the lower end of thecentral portion 403 of thecentral stage 4. The filter 400 is protected by a coaxialcylindrical shield 404, which extends toward the bottom in order to intercept any possible dangerous objects dragged with the suctioned air. - The invention also provides that the control unit can be equipped with a self-cleaning unit of the filter 200 (
fig. 11, 12, 13 ). The self-cleaning unit comprises acompressor 210, which fills astorage tank 211 with compressed air until a known electric valve commands the opening of afast discharging valve 213, when a prearranged pressure level is reached, measured by amanostat 212. The opening of thevalve 213 determines the immediate inflow of a stream of air inside thefilter 200 through anozzle 214. The stream of air has opposite direction with respect to the filtering direction, so that it causes the removal of the particles retained inside the filter. The said self-cleaning unit, which operates with a rate that can be set as required, is arranged between the vibration-proof gasket 700 of themotor 7 and thefilter 200 below, and it is protected externally by acase 2. Thecase 2 is realized so that it can be interposed between thecentral stage 4 and thehead stage 9, in order to maintain the small overall dimensions of the control units, and it has acentral duct 20 for the necessary passing of the suctioned air. - It is obvious that, being fixed the general characteristics illustrated and described herewith, the central unit according to the invention can be susceptible of modifications or variations, anyway comprised in the scope of the patent.
