Abstract
Description
- The invention relates to a fan which is particularly designed for sucking away and removing the polluting or noxious gases from closed rooms, workshops or the like, and particularly for sucking away the exhaust gases of motor-vehicles with running engines while in workshops, garages and the like, said fan comprising an impeller actuated by a co-axial electric motor and enclosed in a housing having a suction mouth and a delivery outlet both of which are substantially arranged parallel to the axis of the impeller and the motor.
- Fans of this so-called "ducted" type are known wherein an impeller and its co-axial actuating motor are both arranged in a tubular housing through which the sucked gas is compelled to flow. Notwithstanding the advantages of this type of fans (namely, constructional simplicity, and compactedness, good performance, possibility to assure a static head), these fans cannot be used for excessively hot gases, or gases containing pollutants and/or explosive mixtures, such as, specifically, for exhaust gases of motor-vehicles, especially in case of malfunctioning of the engines thereof. In fact, motor-vehicle exhaust gases have a high temperature and cause, therefore, an excessive thermal stress of the electric motor which actuates the impeller and is surrounded by said flowing gases. Moreover, these gases contain pollutants which foul the brushes of the motor and often contain as well explosive mixtures which may be ignited by the sparks of the electric motor and may cause dangerous explosions.
- The invention aims to overcome said disadvantages and to provide a fan of the type described in the preamble, which, while maintaining the constructional advantages afforded by the co-axial arrangement of the impeller and the actuating electric motor therefor, avoids any influence of gases on the motor and additionally avoids any risk of explosion due to the ignition of explosive mixtures possibly contained in said gases.
- This problem is solved by the invention in that the sucking mouth and/or the delivery outlet of the housing for the impeller are arranged excentrically to the impeller, beside its actuating electric motor, the latter being mounted outside said housing.
- In a preferred embodiment of the invention, wherein the electric motor (co-axial with the impeller) is arranged on the delivery side and the suction mouth is substantially co-axial with said impeller, said housing for the impeller comprises at least a pair of excentric delivery outlets which are diametrically opposed to each other and communicate, through a pair of respective delivery ducts extending beside said motor, with a common delivery union arranged downstream of the motor and substantially co-axial with the suction mouth. A kind of "ducted" fan is thus obtained which comprises a suction mouth and a delivery union which are substantially co-axial with each other and with the impeller/motor unit, and wherein the electric motor is arranged outside within a space or opening which is surrounded by an annular hollow body including the housing for said impeller, by the two delivery side-ducts and by the delivery union.
- According to a very advantageous construction of this embodiment of the invention the housing for the impeller, with its suction mouth, the two delivery side-ducts connected to the pair of excentric delivery outlets of said housing and the common delivery union to which said delivery ducts are connected, constitute a unitary annular hollow body, provided with a suction mouth and a delivery union which is arranged oppositely and, preferably, co-axially with said suction mouth. This annular hollow body, which, advantageously, may be made of plastics material, mounts interiorly the impeller of the fan and, exteriorly, in the opening enclosed thereby, the electric motor for actuating the impeller, which is co-axial with said impeller.
- In its operative condition, said annular hollow body may be positioned as desired, with its central opening extending in a horizontal, vertical or inclined plane.
- In any case, in the fan according to the invention, the electric motor for actuating the impeller is arranged away from the path of travel of the gases and, therefore, is not affected by them, particularly by the temperature of the exhaust gases of motor-vehicles and pollutants entrained thereby, and it cannot cause any ignition and explosion of inflammable or explosive mixtures contained in said gases.
- The impeller of the fan according to the invention may be constructed as desired according to the type of the fan, which may be either of the centrifugal or axial (helical) types.
- When the fan is of the centrifugal type, the housing for the impeller may have, in cross section transversely to the axis of rotation of said impeller, an outline with two or more scroll-shaped sectors which are angularly staggered from each other and which are connected, each with the wider end thereof, to a delivery outlet, the axis of which is substantially parallel to that of the impeller and of the respective actuating motor.
- The fan according to the invention may be used, as a stationary or mobile unit, in any plant for sucking away noxious or polluting gases from any factory, workshop or the like, and specifically from motor-vehicle repair shops and garages. Due to the constructional simplicity and compactedness, and to the lightweight of the fan according to the invention, the latter is particularly suitable to constitute a mobile, simple and relatively small aspirator which may be used individually for sucking and discharging the exhaust gases of a motor-vehicle from workshops and garages.
- For this purpose, according to a further characteristic of the invention, said fan is mounted on a carriage or trolley, preferably so that its position and level may be adjusted, and its suction mouth is provided with a suction tube, preferably of the rigid and articulated type, which terminates with a funnel in front of the exhaust pipe of a motor-vehicle, while the delivery union is connected to a discharge tube, preferably of the flexible and corrugated type, which is connected to a discharge duct or is extended to the open air outside of the workshop or garage.
- These and other characteristics of the invention and the advantages resulting therefrom will be apparent from the following description of some embodiments which are shown as non-limiting examples in the accompanying drawings, wherein:
- Figure 1 is a side elevational view of a first embodiment of the fan, in the form of a carriage-aspirator for the exhaust gases of a motor-vehicle.
- Figure 2 is an enlarged, fragmentary, horizontal sectional view of the fan of figure 1.
- Figure 3 is a vertical cross sectional view thereof on the line III-III of figure 2.
- Figure 4 shows a half top plan view and a half horizontal longitudinal sectional view of a modified embodiment of the fan of figures 1 to 3.
- Figure 5 shows the fan of figure 4, a half in end view and a half in vertical cross sectional view on the line V-V of figure 4.
- Figure 6 is a diagrammatic longitudinal sectional view of a further embodiment of the fan according to the invention.
- In the figures 1 to 3 there is shown an aspirator for the exhaust gases of motor-vehicles, which is designed to prevent said gases from spreading in workshops, garages and other closed rooms. Said aspirator comprises a fan including a
hollow body 1, animpeller 2 and anelectric motor 3 for actuating saidimpeller 2. - As seen in top plan view, said hollow body has an annular, substantially rectangular shape and comprises, at the suction side, a
transverse portion 4 constituting the housing for t he impeller 2 and enclosing saidimpeller 2. At the outer end side, constituting the front suction side of theannular hoolow body 1, saidportion 4 constituting the housing for theimpeller 2 is formed with a central opening 5 which is co-axial with saidimpeller 2 and is in communication with an outer frusto-conical union ortaper 6 which is secured to thebody 1 and constitutes the suction mouth of the fan. - The annular
hollow body 1 comprises as well twodelivery side ducts 7 which are substantially parallel to each other and to the axis of rotation of theimpeller 2 and which communicate, at diametrically opposite positions, each with arespective delivery outlet 104 of thehousing 4 for theimpeller 2. Saidducts 7 communicate with each other, at the opposite or delivery end of said annularhollow body 1, through atransverse portion 8 of said annularhollow body 1 - At the outer end side constituting the rear delivery side of the annular
hollow body 1 thetransverse portion 8 of said body is provided with acentral delivery union 9 which, preferably, is arranged substantially co-axial with the suction mouth 5 and with the axis of rotation of theimpeller 2. - The
electric motor 3 for actuating theimpeller 2 is co-axial with saidimpeller 2 and is arranged within the intermediate opening orspace 10 of the annularhollow body 1 of said fan, so that it is external with respect to the path of travel of gases. More particularly, saidmotor 3 is secured by means of aflange 11 to the inner end wall of thehousing 4 for theimpeller 2. - The
drive shaft 103 extends into thehousing 4 for theimpeller 2 and mounts saidimpeller 2. In the opening 10 of said annularhollow body 1, on the inner end wall of thetransverse portion 8, there is secured aswitch 12 for themotor 3. - Said annular
hollow body 1 of the fan may be made of any suitable material, if desired, metallic material. However, in a preferred embodiment of the invention, it is made of suitable plastics material and the frusto-conical union 6 of the suction mouth is made of metal. - The fan described above is mounted, so that its level may be adjusted, on a carriage or
trolley 13 which is preferably provided withswingable wheels 14. More particularly, saidcarriage 13 has secured thereto a pair ofside uprights 15 receiving therebetween said annularhollow body 1 of said fan. - A
transverse member 16 is secured to the bottom of saidbody 1 and its ends are slidably engaged in correspondingvertical guide slots 115 formed in the twouprights 15, and may be locked to these uprights by means oflocking nuts 17 which are screwed on the ends of saidtransverse member 16. In order to relieve, at least partially, the annularhollow body 1 of the burden ofmotor 3, the latter may rest on thetransverse member 16 through asupport 18. - Secured to the outer end of the frusto-
conical union 6 constituting the suction mouth of the fan is asuction tube 19 which terminates with means for connection with theexhaust pipe 21 of a motor-vehicle 22. Both thesuction tube 19 and its means for connecting with theexhaust pipe 21 may be made in any manner. More particularly, thesuction tube 19 may be rigid and extend in cantilever fashion from thebody 1 of the fan, and it may terminate with a funnel-shaped portion 20 adapted to receive theexhaust pipe 21 of a motor-vehicle. The level of thebody 1 is adjustable along theuprights 15 of thecarriage 13 so as to bring thefunnel 20 of thesuction tube 19 to the level of theexhaust pipe 21. For the same purpose, saidsuction tube 19 may also be of the flexible type. In the embodiment of figure 1, thesuction tube 19 is constituted by two rigid tube lengths 119,219 which are mutually coupled so as to be rotatable with respect to each other with their ends made circular in atransverse plane 319 which is at an angle of 45 with respect to the axis of the twotube lengths 119 and 219. By rotating the tube length 219 in theinclined plane 319 with respect to thestationary tube length 119, the end of the tube length 219 provided with thefunnel 20 will be displaced laterally and vertically at the same time. - The
delivery union 9 of the annularhollow body 1 of the fan is connected to any duct or pipe through which said exhaust gases of the motor-vehicle 22 are conveyed out of the room (workshop, garage, or the like) where saidvehicle 22 is present. In the exemplary embodiment shown herein, saiddelivery union 9 is connected to a flexiblecorrugated pipe 23 accommodating therein arod 24 articulated at 124 to abracket 25 which is secured to thedelivery union 9. When the fan is at rest, thecorrugated pipe 23 is axially pressed and contracted on therod 24, and is held in this condition by means of atransverse pin 26, or the like, inserted crosswise through the free end portion of said rod, as shown in figure 1. In this condition, therod 24 may be lifted angularly and be used as a handle for displacing manually thecarriage 13 supporting said fan. In operation, thepin 26 is pulled out and the corrugated pipe is extended beyond therod 24, for example, to bring the end of said pipe out of the door or the window of the workshop or garage. In these conditions, saidrod 24 may even assume a horizontal position while remaining within thepipe 23. - During the operation, the
impeller 2 sucks the exhaust gases of the motor-vehicle 22 through thefunnel 20, thepipe 19 and thesuction mouth 6, and impels them through the twodelivery outlets 104 of thehousing 4 and adjacentdelivery side ducts 7 into thetransverse portion 8 to flow out therefrom through thedelivery union 9 andtube 23 to be conveyed out of the closed room. Themotor 3 for actuating theimpeller 2 is never contacted by the evacuated gases and, therefore, is not warmed up or fouled thereby and it cannot cause the ignition of any explosive mixture in said exhaust gases. - The
impeller 2 is usually constructed so as to obtain a centrifugal fan. This type operation of the fan assures a sufficient even when thehousing 4 for the impeller has not, interiorly, a scroll configuration and has instead a rectangular or square configuration with substantially rectilinear sides, as shown in figure 3. In the embodiment of figures 4 and 5, however, theportion 4 of the annularhollow body 1, which constitutes the housing for theimpeller 2 has an inside configuration comprising two scroll-shaped sectors 204 which are staggered 180 from each other and communicate, through arespective delivery outlet 104 of thehousing 4, with adelivery side duct 7, as clearly shown in the sectional view of figure 5. Under any other respect, the embodiment of figures 4 and 5 is substantially similar to the embodiment of figures 1 to 3, the similar parts being designated by the same reference numerals. - In the embodiment of the fan according to the invention, diagrammatically shown in figure 6, the
housing 4 for the impeller comprises afront suction mouth 6 which is co-axial with theimpeller 2 and, only on one side, adelivery outlet 104 connected to a singlecorresponding delivery duct 7 extending substantially parallelly to the axis of theimpeller 2 beside its actuatingmotor 3 and terminating with adelivery union 9. Themotor 3 is co-axial with theimpeller 2 and is fixed to the outside thehousing 4, for example, by means of aflange 11. - Of course, the invention is not limited to the exemplary embodiments described and shown herein, and broad changes and modifications, especially of constructional nature, may be made thereto. Specifically, the fan according to the invention may be used for sucking away not only the exhaust gases of motor-vehicles, but as well any other noxious or polluting gases from closed rooms and workshops, in any aspirator systems or plants, in aspirator kitchen-hoods or the like, and as well for any other use wherein the fan of the invention may show useful. Mo reover, it is apparent that the fan according to the invention may be used with no carriage, and it may be fixedly arranged within any suction or delivery duct.
