Abstract
Description
- This patent application is a continuation of U.S. patent application Ser. No. 09/563,821 filed May 3, 2000.
- The present invention relates broadly to air filtration apparatus and, more particularly, to an air filtration device that is configured for abutment against an electrical outlet providing operational power for the device, with atmospheric air flowing into an intake on the front surface of the device, and filtered air being emitted through vents provided on the side of the device.
- As the atmosphere in general becomes more polluted and the general population becomes more aware of discomforts associated with dirty air, air filtration devices of all shapes, types and sizes have become more popular. One type of air filtration device provides a small fan for use in a smoky environment. These devices typically will include an electric fan contained in a small housing for tabletop use, with a filter through which the air is directed for removal of smoke and other such contaminants. These small fans are useful for removing odors and contaminants from a confined space, since they typically take up little space themselves and move a relatively small volume of air.
- Such current designs, while effective, leave room for improvement in the areas of noise control, air dispersion and filter management.
- An air filtration device is provided for intake of atmospheric air, assistance in removal of contaminants from the atmospheric air, expulsion of filtered air and configured for operational association with a generally vertically oriented surface. The device includes a housing defining an air flow path therethrough having a front surface, at least one side surface and a rear surface; at least one air inlet formed in the front surface of the housing; and at least one air outlet formed in the housing intermediate the front surface and the rear surface, for cooperation of the air outlet with a generally vertical surface to which the air filtration device is associated for enhanced dispersion of filtered air expelled through the air outlet. A filter is mounted to the housing in the air flow path and an impeller is provided for moving air through the housing along the air flow path from the at least one air inlet to the at least one air outlet, with the impeller being mounted to the housing.
- The air outlet may be formed on the at least one side surface and the air flow path may be defined from the air inlet on the front surface through the filter, through the impeller and outwardly through the air outlet. Also, the side surface may be curved and the air outlet may be formed as a series of vents along the curvature of the side surface.
- The air filtration device may further include a bumper member attached to the rear surface of the housing for abutment with a generally vertical surface to which the air filtration device is associated for orientation of the device with the vertical surface. The bumper member may also be formed from resilient material for enhanced noise reduction when the air filtration device is in operation. The filter can be formed as a generally planar member selectively removable from the housing and can include a notch formed therein for directing insertion of the filter in a correct orientation with respect to the air flow path. The housing may include a locating surface formed thereon and corresponding with the notch in the filter to orient the filter in the housing. The housing may also include an icon formed thereon at a position corresponding with the notch in the filter when the filter is inserted in the housing for enhanced visual indication of proper filter orientation.
- The air filtration device can include an electric motor for driving the impeller and a pair of electric prongs extending outwardly from the rear surface of the housing for operational engagement with an electrical wall outlet for supplying electric power to the electric motor. The pair of electrical prongs can be configured with each prong in the pair having substantially the same dimensions, so that said air filtration device may be connected to an electrical outlet without regard to the dimensional differences between the socket openings.
- The air filtration device may further include an indicator for communicating that the filter should be changed, the indicator providing information after a predetermined period of operation of the air filtration device has passed. The impeller may be driven electrically and the indicator can include an electric timer circuit operationally associated with the impeller for determining when a predetermined time of impeller operation has passed.
- A lamp may be mounted to the housing for illumination when the impeller is in operation, with the lamp being in electrical communication with the electric timer circuit and configured to provide pulsating illumination when a predetermined time of impeller operation has passed. A reset switch can be provided in electrical communication with the electric timer circuit to selectively reset the electric timer circuit to a zero operational time setting.
- It will be understood by those skilled in the art that variations on that which is described above may be achieved by addition or omission of the features of the features above described.
- Accordingly, an air filtration device is provided for intake of atmospheric air, assistance in removal of contaminants from the atmospheric air, expulsion of filtered air and configured for operational association with a generally vertically oriented surface, and includes a housing for abutting attachment to an electrical outlet, the housing defining an air flow path therethrough and having a front surface, at least one side surface and a rear surface; at least one air inlet formed in the housing; at least one air outlet formed in the housing intermediate the front surface and the rear surface; a filter mounted to the housing in the air flow path; an electrically driven impeller for moving air through the housing along the air flow path from the at least one air inlet to the at least one air outlet, with the impeller being mounted to the housing; and a pair of electric prongs extending outwardly from the rear surface for operational engagement with an electrical wall outlet for supplying electric power to the impeller. The pair of electrical prongs can be configured with each prong in the pair having substantially the same dimensions, so that said air filtration device may be connected to an electrical outlet without regard to the dimensional differences between the socket openings. A bumper member is attached to the rear surface of the housing for abutment with a generally vertical surface to which the bumper member may abut for orienting the device with the vertical surface. The bumper may be formed from resilient material for damping vibrations received from the housing to provide enhanced noise reduction when the air filtration device is in operation.
- The air filtration device includes an air inlet that is formed on the front surface of the housing and the air flow path is defined from the air inlet on the front surface through the filter, through the impeller and outwardly through the air outlet. The filter may be formed as a generally planar member selectively removable from the housing and includes a notch formed therein for directing insertion of the filter in a correct orientation with respect to the air flow path. The housing may include a locating surface formed thereon and corresponding with the notch in the filter to orient the filter in the housing. The housing may include an icon formed at a position corresponding with the notch in the filter when the filter is inserted in the housing for enhanced visual indication of proper filter orientation.
- The air filtration device may include an indicator for communicating that the filter should be changed, the indicator providing information after a predetermined period of operation of the air filtration device has passed. The impeller may be driven electrically and the indicator may include an electric timer circuit operationally engaged with the impeller for determining when a predetermined time of impeller operation has passed. The air filtration device also can include a lamp mounted to the housing for illumination when the impeller is in operation, the lamp being in electrical communication with the electric timer circuit and configured to provide pulsating illumination when a predetermined time of impeller operation has passed. A reset switch can be provided in electrical communication with the electric timer circuit to selectively reset the electric timer circuit to a zero operational time setting.
- It should also be understood that the above-described features may be combined under a single, full-featured unit. In that regard, an air filtration device for intake of atmospheric air, removal of contaminants from the atmospheric air, expulsion of filtered air and configured for operational association with a generally vertically oriented surface, includes a housing for abutting attachment to an electrical outlet, the housing defining an air flow path therethrough and having a front surface, a curved side surface and a rear surface; at least one air inlet formed in the front surface of the housing; and a series of vents formed in the side surface intermediate the front surface and the rear surface, for cooperation of the vents with a generally vertical surface to which the air filtration device is associated for enhanced dispersion of filtered air expelled through the vents. A filter is mounted to the housing intermediate the at least one air inlet and the at least one air outlet, with the filter being formed as a generally planar member selectively removable from the housing and including a notch formed therein for directing insertion of the filter in a correct orientation with respect to the air flow path. The housing may include a locating surface formed thereon and corresponding with the notch in the filter to orient the filter in the housing. An electrically driven impeller is provided for moving air through the housing along the air flow path from the at least one air inlet to the vents, with the impeller being mounted to the housing. A pair of electric prongs extends outwardly from the rear surface for operational engagement with an electrical wall outlet for supplying electric power to the impeller. The pair of electrical prongs can be configured with each prong in the pair having substantially the same dimensions, so that the air filtration device may be connected to an electrical outlet without regard to the dimensional differences between the socket openings. A bumper member is attached to the rear surface of the housing for abutment with a generally vertical surface to which the bumper member may abut for orienting the device with the vertical surface. The bumper member may be formed from resilient material for damping vibrations received from the housing for enhanced noise reduction when the air filtration device is in operation.
- The air filtration device may include an indicator providing information after a predetermined time period of operation of the air filtration device has passed. The indicator may include an electric timer circuit, as described above, to determine how long the impeller has been in operation and, when the time period has passed, an indicator lamp provides a pulsing illumination. The electric timer circuit may also be provided with a reset switch to selectively reset the electric timer circuit to a zero operational time setting.
- By the above, the present invention provides an air filtration device that will plug directly into an outlet and utilize the wall behind the device for dispersion of filtered air, while directing air intake from a central source. The present invention also provides a handy visual indication of when the filter is placed in proper orientation with respect to air flow. Further, the device provides reduced noise by damping vibrations transmitted from the housing to the wall against which the device is mounted.

- Turning now to the drawings and, more particularly to FIGS. 1, 2 and3, an air filtration device for intake of atmospheric air, filtration of the atmospheric air and emission of filtered air is illustrated generally at 10 and includes a
housing 12. Thehousing 12 includes a generallycurved side wall 28 fixed to a generallyflat front portion 29. A generallyplanar door 18 is fixed to theflat front portion 29, using hinges 19 as seen in FIG. 3. Referring back to FIG. 1, thedoor 18 includes afront surface 14 and a generally circular perforatedair inlet grill 16.Tabs 20 are provided on each side of the door as seen in FIGS. 1 and 2, for ease of opening for filter replacement, as will be seen in greater detail hereinafter. The door covers approximately 80% of the front surface of thedevice 10. The remainder of the front surface is covered by acontrol panel 22. This ratio is primarily a function of aesthetics, and does not effect the performance of thedevice 10. Acentralized rocker 24 is provided in thecontrol panel 22 to control an internal switch to activate and deactivate thedevice 10 and anindicator light 26 is provided above therocker switch 24 which illuminates when thedevice 10 is activated and, as will be seen in greater detail hereinafter, flashes when thefiltration device 10 has been in operation for a predetermined time period. A plurality ofvents 30 are provided around thecurved side surface 28 to act as air outlets. - Turning now to FIG. 3, a
rear surface 32 is provided adjacent and integral with theside surface 28. Therear surface 32 is curved to conform to the shape of theside surface 28. - In order to facilitate electrical power application, a pair of
electrical prongs 34 extend outwardly from therear surface 32 for operational engagement with a conventional electrical outlet. Theelectric prongs 34 are each formed of like dimensions, so that the air filtration device may be connected to an electrical outlet without regard to the dimensional differences between the socket openings. Accordingly, thedevice 10 may be oriented properly, with theprongs 34 above thevents 30, no matter what orientation a polarized socket is mounted to the outlet E. Further, the prong arrangement allows thedevice 10 to be mounted in the lower of the two sockets in an outlet pair, without regard to the dimensional differences between the socket openings. The location of theprongs 34 with respect to the top of thehousing 12 ensures that the uppermost socket in a socket pair will remain available for use by other devices when thedevice 10 is in operation, as seen in FIG. 8. - A
bumper member 36 provided below theelectrical prongs 34 for abutment with a vertical surface or wall W against which thedevice 10 is mounted, as seen in FIGS. 7 and 8. Thebumper member 36 assists a user in orienting thedevice 10 with respect to a wall surface W. Further, thebumper member 36 may be formed from resilient material. Aresilient bumper member 36 absorbs and dampens vibrations from thehousing 12 to reduce or prevent their transmission to the wall W which reduces the noise associated with an operationalair filtration device 10. - Turning now to FIGS. 4, 5 and6, the internal components of the
device 10 are illustrated. It will be appreciated that in order to filter air, an air flow path is defined through thehousing 12, afilter 40 is provided and a device is provided to move the air. As seen in FIG. 5, the air flow path, illustrated by arrows, is defined by air movement generated within thedevice 10, from theair inlet 16, through thedevice 10 and outwardly through thevents 30. Animpeller 54 is provided to move air through thedevice 10. Theimpeller 54 is a basket-like structure having two mountingrings 55 separated by a plurality ofvanes 57 that are curved to draw air from outside theimpeller 54 and drive the air outwardly through the side of theimpeller 54. - The
impeller 54 is rotated by anelectric motor 46. As seen in FIG. 5, themotor 46 includes anarmature 56 attached to theimpeller 54. Electrical excitation of themotor 46 causes thearmature 56 to rotate, thereby rotating theimpeller 54. - As also seen in FIGS. 4, 5 and6, a
filter 40 is provided for filtering incoming air. Thefilter 40 can be directional in that a particular surface can be facing incoming air so that contaminated air is drawn through thefilter 40 in a direction optimal for air filtration. Oneuseful filter 40 includes afront filtration surface 41, arear scrim 45 and is charcoal activated. It will be appreciated by those skilled in the filtration art that other filter compositions may be used. In particular, some filters may be configured to remove bathroom odors and some filters may be configured to remove kitchen odors. Other types of filters may include an increased charcoal content for smoke filtration. It is contemplated that various types of filters may be used with the presentair filtration device 10 without reducing the effectiveness of any of the filters or the overall filtering efficacy of thedevice 10. Thefilter 40 is formed with anotch 42 in one corner, as will be explained in greater detail hereinafter. - An
internal baffle plate 60 is provided to provide a surface for mounting thefilter 40 and to direct air inwardly toward the impeller. A conicalinner surface 62 is provided in thebaffle plate 60 to provide a nozzle effect to increase the effectiveness of thefiltration device 10. A locatingsurface 43 is formed as a raised rib in a lower corner of thebaffle plate 60 corresponding to thenotch 42 in thefilter 40 for orienting the filter in thehousing 12. Anicon 44 is applied to thebaffle plate 60 adjacent the locatingsurface 43, for visual indication of proper filter orientation. As also illustrated in FIG. 4, theair filtration device 10 is configured for mounting against an electrical outlet E mounted on a wall W. - As seen in FIGS. 5 and 6, the air flow path is defined through the
housing 12 and illustrated by arrows. Atmospheric air enters theair filtration device 10 through theair inlet grill 16 and then travels through thefilter 40 for contaminant removal. With reference to FIG. 4, the air travels down the conicalinner surface 62 of theinternal baffle plate 60 and enters aplenum 63 containing the rotatingimpeller 54. Theimpeller 54 draws the air along the flow path to an area within the rotatingvanes 57 and the air is directed then outwardly through the rotatingvanes 57 through theplenum 63 and eventually out through thevents 30 in thecurved side wall 28. - Another feature of the present invention is the ability to determine in general when the
filter 40 should be replaced. Under normal operation, thefilter 40 should be replaced after a predetermined period of time. It may be presumed that the time period of filter contamination coincides with the operating period of theimpeller 54 and therefore themotor 46. To that end, atiming circuit 48 is provided in thewiring 50 that connects theswitch 25 to themotor 46. As also seen in FIGS. 5 and 6, therocker 24 operates a remotely disposedswitch 25, with therocker 24 projecting through thecontrol panel 22. It should be appreciated by those skilled in the art that such a timing circuit is a basic electronic device and can be configured in any number of ways. The timing circuit is also in electrical communication with theindicator lamp 26 which illuminates upon electrical excitation of themotor 46. When thetiming circuit 48 has reached the end of a predetermined time period, theindicator light 26 is caused to pulsate, or flash, which is an indication that thefilter 40 should likely be replaced. Thetiming circuit 48 also includes areset switch 49 which allows an operator or owner to reset the timer once the filter is replaced. Optionally, thedevice 10 may be provided without atiming circuit 48 as illustrated in FIG. 6. - Referring now to FIGS. 7 and 8, in operation, the
air filtration device 10 of the present invention is plugged into an electrical outlet usingelectrical prongs 34 in a generally conventional manner. Therear surface 32 of thehousing 12 is closely adjacent to the electrical outlet E and may abut the electrical outlet E. Thebumper member 36 abuts the wall W or outlet E or indeed, any vertical surface to which thedevice 10 may be fixed in order to provide proper orientation of thedevice 10 with respect to the wall surface W and, if thebumper member 36 is resilient, to provide a damping effect for motor vibrations that may be transmitted from thehousing 12 during operation. Once adevice 10 is against the wall W therocker 24 is moved into an “on” position, which causes theswitch 25 to provide electrical excitation to themotor 46 which, in turn, causes theimpeller 54 to rotate, thereby drawing atmospheric air inwardly through theair inlet grill 16. The atmospheric air is drawn through thefilter 40. and is caused to travel along the air flow path as defined in FIGS. 5 and 6. As the air passes through thefilter 40 contaminants are removed and the filtered air travels intermediate thevanes 57 of theimpeller 54 and is expelled through thevents 30 formed in thecurved side surface 28. As seen in FIG. 7, and as will be appreciated by those skilled in the art, the filtered air is dispersed along an approximately 315° curve and the wall W acts as a baffle to enhance air dispersion from thedevice 10. Therefore, theair filtration device 10 of the present invention draws air from a generally focused source of contaminated air and provides a dispersed wave of filtered air to enhance the effectiveness of the filter operation. It should be noted that the relationship of thedevice 10 and the wall W, along with the vent location, is illustrated in FIG. 8. - As previously stated, the present invention provides a user with visual enhancements with respect to filter replacement. With reference to FIG. 9, a filter is shown spaced a distance from the
baffle plate 60 to which it is to be mounted. As can be seen, thefilter 40 includes anotch 42 formed in a lower right hand corner of thefilter 40. Thebaffle plate 60 includes theicon 44 which is preferably shaped as a keyhole, yet may be shaped in any configuration imaginable. By orienting thenotch 42 in abutment with the locatingsurface 43 and such that theicon 44 is visible through thenotch 42 when thefilter 40 is in place, as seen in FIG. 10, thefilter 40 is oriented properly with respect to air flow. Should thefilter 40 be inserted in a reverse manner, theicon 44 would not be visible, because thenotch 42 would not be in a position to allow the user to see theicon 44. Additionally, the locatingsurface 43 acts to physically orient thefilter 40. Therefore, the combination of thenotch 42, theicon 44, and the locatingsurface 43 allows someone replacing the filter to easily determine when the filter is in proper orientation with respect to air flow. - By the above, the present invention provides a compact air filtration device that provides enhanced effectiveness, the ability to determine when a filter should be replaced, and a visual indication of proper filter orientation with respect to air flow.
- It will therefore be readily understood by those persons skilled in the art that the present invention is susceptible of a broad utility and application. Many embodiments and adaptations of the present invention other than those herein described, as well as many variations, modifications and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing description thereof, without departing from the substance or scope of the present invention. Accordingly, while the present invention has been described herein in detail in relation to its preferred embodiment, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for purposes of providing a full and enabling disclosure of the invention. The foregoing disclosure is not intended or to be construed to limit the present invention or otherwise to exclude any such other embodiments, adaptations, variations, modifications and equivalent arrangements, the present invention being limited only by the claims appended hereto and the equivalents thereof.
