Description

IN-LINE CENTRIFUGAL AIR ASPIRATOR Technical field
The present invention relates to an in-line centrifugal air aspirator. Background Art Wall-mounted, ceiling-mounted or flush-mounted aspirators constituted by a motorized fan which operates inside a containment enclosure provided with one or more intake ports for a corresponding number of intake pipes and with a port for discharging the aspirated air are currently known and used extensively in homes, flats, industries and other fields.
Such aspirators are further provided with an electronic control unit which is accommodated in a separate box-like container, which is generally fixed outside the enclosure.
Although known aspirators are extensively used and appreciated, they have aspects which can be improved.
First of all, such aspirators generally have a bulk which prevents their installation in particularly confined spaces, such as for example the ones increasingly often available in new dwellings, in which space is increasingly tight. Further, known aspirators have containment enclosures which are sized in proportion to the diameter of the intake and discharge ports, and accordingly have as many different shapes and dimensions as there are series of diameters of ports which the manufacturer provides for the market. Known types of aspirator are also generally awkward to install on a wall or ceiling, since the installation technician must at the same time support the object and fix it.
Likewise, the operation for separating the motor supporting flange from the enclosure for inspection of said motor is typically awkward, this operation requiring the unscrewing of the screws which connect said flange to the enclosure until they can be extracted. Disclosure of the Invention
The aim of the present invention is to provide an in-line centrifugal air aspirator which is capable of obviating the drawbacks shown by known types of aspirator. Within this aim, an object of the present invention is to provide an aspirator which is more compact than known aspirators and therefore can be installed conveniently even in relatively tight spaces which are unfeasible for known aspirators.
Another object of the present invention is to provide an aspirator which can be installed easily for coupling to intake and discharge pipes having a cross-section whose dimensions are usually standardized in the field, depending on the requirements of the buyer and/or user.
Another object of the present invention is to provide an aspirator which is simpler to install and handle during maintenance with respect to known types.
Another object of the present invention is to provide an in-line centrifugal air aspirator which can be manufactured cheaply with known systems and technologies.
This aim and these and other objects, which will become better apparent hereinafter, are achieved by an in-line centrifugal air aspirator, which comprises a motorized fan which operates inside a containment enclosure provided with one or more suction ports and with a port for discharging the aspirated air, a box for containing an electronic control unit, a supporting flange for said fan and for the motor that drives it, and wall- or ceiling-mounting means being associated with said enclosure, said aspirator being characterized in that said containment box for the electronic unit is integrated within said containment enclosure.
Brief description of the drawings
Further characteristics and advantages of the invention will become better apparent from the following detailed description of a preferred but not exclusive embodiment thereof, illustrated by way of non-limiting example in the accompanying drawings, wherein:
Figure 1 is a first perspective view of an aspirator according to the invention; Figure 2 is a second perspective view of the aspirator according to the invention;
Figure 3 is a view of a first detail of an aspirator according to the invention;
Figure 4 is a view of a second detail of an aspirator according to the invention;
Figure 5 is another partially exploded perspective view of an aspirator according to the invention. Ways of carrying out the Invention
With reference to the figures, an in-line centrifugal air aspirator according to the invention is generally designated by the reference numeral 10.
The air aspirator 10 comprises a motorized fan 11, which operates inside a containment enclosure 12 provided with one or more intake ports, the single intake port 13 (in the exemplary embodiment of the invention described here) and a discharge port 14 for the aspirated air.
A box 15 for containing an electronic control unit 16, a supporting flange 17 for the fan 11 and for the motor that drives it, and wall- or ceiling- mounting means are associated with the enclosure 12.
The containment box 15 for the electronic unit 16 is integrated within the containment enclosure 12.
The containment box 15 protrudes from the enclosure 12 only with the perimetric flaps 15a designed for fixing to the edges of the complementarily shaped opening formed in the enclosure 12.
The box 15 is closed toward the outside by a cover 18, in which there is a passage hole for a handle 19 for controlling the electronic unit which lies inside the box 15, which can be managed manually by a user.
Conveniently, the box 15 and its cover 18 are made of plastic material.
This configuration with a box 15 inside the enclosure 12 makes the aspirator 10 according to the invention more compact than known aspirators and therefore allows to install it conveniently even in relatively tight spaces which are unfeasible for known aspirators.
The aspirator 10, as shown in the figures, in fact is extended mainly along two dimensions, length and width, while its thickness is particularly low and is substantially proportionate only to the height of the vanes of the fan 11.
The containment enclosure 12 is constituted by a box-like body 20, which is shaped like a parallelepiped and is formed by four faces made of metal plate which are mutually opposite in pairs. The box-like body 20 thus forms two openings, an intake opening and a discharge opening, each of which is adapted to be closed by a corresponding cover, 21 and 22 respectively, chosen among a series of covers, each provided with at least one intake port 13 or discharge port 14 having a predefined cross-section. Each cover 21 and 22 is provided with perimetric rims 23 and 24 for coupling to the corresponding opening.
The covers 21 and 22 for supporting the ports 13 and 14 are conveniently made of plastic material and the intake and discharge pipes are coupled thereon. The box-like body 20 is standardized in its dimensions, so that it is possible to apply to the openings covers, such as the covers 21 and 22 described here, which have identical perimetric dimensions and are different in the number and size of the ports.
The covers 21 and 22, in the embodiment of the invention described here by way of non-limiting example, are fixed to the openings by means of the perimetric edges 23 and 24, which are fixed by means of screws to the superimposed underlying flaps of the box-like body 20.
In this manner, the aspirator 10 according to the invention can be configured easily for coupling to suction and discharge pipes having any cross-section, depending on the requirements of the buyer and/or user, simply by selecting beforehand the cover provided with the port which has the dimensions that are most suitable for the suction requirements; this is different from what occurs for known aspirators, as mentioned above.
The fixing means are constituted by two protrusions which protrude symmetrically from two mutually opposite lateral faces 20a and 20b of the enclosure 12, each of said protrusions being adapted to be inserted in a corresponding slot 25 which forms a contact edge 26 for the protrusion accommodated therein.
Each slot 25 is provided on a bracket 27 to be fixed to a wall or ceiling.
In the embodiment described here by way of non- limiting example of the invention, each protrusion is formed by the threaded stem 28a of a fixing knob 28.
The threaded stem 28a is adapted to be screwed into a corresponding complementary thread 28b which is formed on the respective face 20a or 20b of the enclosure 12.
Each bracket 27 is formed by a plate-like element which comprises a first flat portion 29, which is designed to face the mounting surface, and a second portion 30, which lies transversely to the first portion 29 and on which the slit 25 is provided.
The slit 25 is substantially L-shaped and is open on one side 30a of the second portion 30.
In the exemplary embodiment of the aspirator 10 described here, the brackets 27 are joined together so as to form a single substantially C-shaped bracket-mounting body 31, the central portion of which comprises the first flat portions 29 which are adapted for fixing to a wall or ceiling and whose lateral edges provide the second portions 30 with a slot 25.
Such bracket mounting allows to install the aspirator 10 very easily and quickly on a wall or ceiling. It is in fact sufficient to first fix the single body 31 to a wall or ceiling, hang from it the enclosure 12 of the aspirator 10, to which the knobs 28 are screwed, inserting the stems 28a of the knobs in the slots 25 and making them slide until the stems rest in an optimum position on a supporting edge 26 of the respective slot 25; at this point, one proceeds by screwing on the knob 28 so as to stabilize the connection between the enclosure 12 and the bracket mounting body 31.
The supporting flange 17 for the fan 11 and the motor is formed by a substantially circular removable panel, which is rigidly coupled to the containment enclosure 12 by way of four threaded elements 32. The threaded elements 32 are screwed to the enclosure 12 and are each suitable for mating with a corresponding slot 33, which is formed on the flange 17 by a first portion 33a which is larger than the diameter of the head of the threaded element 32 and by a second contiguous portion 33b whose dimensions are smaller than the diameter of said head. The described coupling, of the substantially bayonet-like type, allows to disengage the flange 17 without unscrewing fully the threaded elements 32, since it is sufficient to unscrew said threaded elements partially, turn the flange 17 until the first portion 33a of the slots 33 lies at the heads of the threaded elements 32, and separate the flange 17 from the enclosure 12. This refinement makes it much faster and convenient to disassemble the fan and the motor from the enclosure 12 and consequently facilitates maintenance and repair operations.
Further, the motor for driving the fan 11 is connected to the electronic unit 16 by means of a first connector 34 of a per se known type, which is adapted to be connected to a corresponding first socket 35 which is provided on the electronic unit 16, the first connector 34 being easily removable manually without using screwdrivers or other tools.
This additional refinement further simplifies the disassembly and subsequent reassembly of the aspirator, allowing the operation for disengaging the flange 17 and the operation for disconnecting the control electronics to be completely manual.
Connection/disconnection from the electrical mains is likewise simple and quick thanks to the presence of a second connector 36, which is adapted to connect, by means of a corresponding socket 37, the electronic unit 16 to the power supply cable 38; in this case also, the second connector 36 can be removed manually from the corresponding socket 37 on the electronic unit 16 without using screwdrivers or other tools.
If it is necessary to act on the power supply, it is sufficient to disconnect the second connector 36 from its socket 37 on the electronic unit 16 and act on the cable 38 or on the connector 36 without having to remove the entire electronic unit 16 from the box 15, or worse still from the enclosure 12, or better still even without having to disconnect the enclosure 12 from the wall or ceiling from which it hangs.
In practice it has been found that the invention thus described solves the problems noted in known types of in-line centrifugal air aspirator.
In particular, the present invention provides an aspirator which is more compact than known aspirators and is therefore installable conveniently even in relatively tight spaces which are not accessible for known aspirators. Moreover, the present invention provides an aspirator which can be configured easily for coupling to suction and discharge pipes having any cross-section, according to the requirements of the buyer and/or user.
Further, the present invention provides an aspirator which is easier to install and handle during maintenance with respect to known types. Moreover, the present invention provides an in-line centrifugal air aspirator which can be produced cheaply with known systems and technologies.
In practice, the materials employed, so long as they are compatible with the specific use, as well as the dimensions, may be any according to requirements and to the state of the art.
