Vehicle air freshener module

Abstract

An air freshener module is installed in a compartment slot formed in the dashboard of a vehicle. The module includes a body having a front section and a rear section. The rear section has an air inlet port that is adapted for coupling to the vehicle AC tube. The front section defines a plenum or interior housing space configured to receive an air freshener receptacle or holder that is movable between an open state and a closed state. The front end of the interior housing space defines an air outlet port. An air passageway extends between the air inlet port and the air outlet port. During operation, air admitted through the air inlet port is vented into the interior housing spaced occupied by the air freshener holder, enabling air to pass through an air freshener element and thereby communicate odorized air into the cabin. An adjustable closure regulates the amount of air delivered into the plenum.

(11) A vehicle air freshener module 100 is presented in various configurations in the illustrations of FIGS. 1 through 5, according to a first embodiment of the invention. The illustration of FIG. 1 shows the air freshener module 100 installed in the dashboard 110 of a vehicle, such as in an area proximate to the steering wheel to permit ready access by the driver. As shown in FIG. 2, the air freshener module 100 is adapted for fluid connection to an air passageway or tube 112 of the vehicle air conditioning (AC) system. The air freshener module 100 vents air conveyed by the AC system through an air freshening element housed in the air freshener module 100 and then vents the scented air into the vehicle cabin space, thereby odorizing the ambient cabin air. As shown in FIG. 1, the air freshener module 100 is equipped with an air control panel 102 having a user control switch 104 that regulates the amount of air vented through air freshener module 100.

(12) As shown in FIGS. 2 through 5, the air freshener module 100 of the present embodiment includes a casing or body 120 having a front section 122, a mid section 124, and a rear section 126. The mid section 124 is disposed between and contiguous with the front section 122 and the rear section 126. The front section 122 defines an interior space or cavity 160 (FIG. 4) having a front opening that defines an air outlet end 138 of body 120. The air outlet end 138 faces towards the vehicle cabin during installation of the air freshener module 100. The rear section 126 defines an interior cavity 164 having an opening that defines an air inlet end 136 of body 120. The mid section 124 defines an interior cavity 162 that is contiguous with the interior cavity 160 of front section 122 and the interior cavity 164 of rear section 126.

(13) Each one of the front section 122, the mid section 124, and the rear section 126 is open-ended. This open-ended contiguous arrangement among the front section 122, the mid section 124, and the rear section 126 defines an airway or air passageway 166 extending between the air inlet end 136 at rear section 126 and the air outlet end 138 at the front section 122 of the body 120. The air passageway 166 extends generally along a longitudinal dimension of body 120. The front section 122, the mid section 124, and the rear section 126 of the present embodiment cooperatively form an integral, unified, single-body construction of body 120.

(14) The front section 122 depicted herein has a hollow-body construction in the form of a generally shell-type structure. The shell-type structure includes an axially-extending, outer peripheral sidewall 170 having an upper end 171 and a lower end 172. The outer peripheral sidewall 170 extends in a generally axial or longitudinal direction. The front section 122 further includes a radially-extending, back sidewall 173 that extends radially inward (with respect to a central longitudinal axis 128) from the outer peripheral sidewall 170. The combination of the outer peripheral sidewall 170 and the back sidewall 173 cooperatively defines the interior cavity 160 of the front section 122.

(15) Similarly, the mid section 124 of body 120 has a hollow-body construction in the form of a generally shell-type structure. The mid section 124 is contiguous with the front section 122 at the back sidewall 173 of the front section 122. The interior cavity 162 defined by the mid section 124 has a transverse dimension that is smaller than the interior cavity 160 defined by the front section 122. The mid section 124 includes a radially-extending back surface 175.

(16) During installation, as best shown in FIG. 4, the air freshener module 100 is arranged so that the tubular rear section 126 slidingly fits into the air tube 112. The advancement or insertion of the rear section 126 into the air tube 112 is complete when the air tube 112 abuts against the back surface 175 of the mid section 124. The rear section 126 of the body 120 of the present embodiment has a generally tubular construction that is appropriately sized and dimensioned to fit within the air tube 112 of the vehicle AC system in a frictional male-female fashion during installation. This frictional male-female interfit arrangement provides a suitable air-tight coupling between the air freshener module 100 and the air tube 112 that facilitates the transfer of fresh air from the air tube 112 into the air freshener module 100 via the air inlet end 136 at the rear section 126. The interior cavity 164 defined by the rear section 126 of the present embodiment has a transverse dimension that is generally coextensive with the interior cavity 162 defined by the mid section 124.

(17) The air freshener module 100 further includes a movable air freshener receptacle or holder 130. The air freshener holder 130 is housed during assembly in the interior cavity 160 of front section 122. The air freshener holder 130 of the depicted embodiment is a removable component. In its assembled position, the air freshener holder 130 is configured in a pivotable relationship within the body 120, and more specifically with the front section 122 of the body 120. The air freshener holder 130 can pivot between a fully open position (FIG. 4) and a fully closed position (FIG. 5). The front section 122 of the body 120 is suitably sized and configured to facilitate the assembled placement of air freshener holder 130 within the interior cavity 160 and to accommodate the full range of operative pivoting motion of air freshener holder 130. The air freshener holder 130 is configured to hold, contain, or otherwise house an air freshener element.

(18) The air freshener holder 130 of the present embodiment has an enclosed, generally V-shaped configuration including a front panel 140, a partition or mid panel 141, a rear panel 142, and a pair of sidewalls 148 and 149, as best shown in FIG. 3. The front panel 140 defines the front end of air freshener holder 130, while the rear panel 142 defines the back end of air freshener holder 130. The front panel 140 is disposed in a spaced-apart, opposing, generally parallel relationship with the mid panel 141. The rear panel 142 is disposed in a spaced-apart, opposing, angled relationship with the mid panel 141. The air freshener holder 130 has an open, wide-mouth top 131 and a relatively narrow bottom end 150. The air freshener holder 130 is open at the top 131 and closed at the bottom end 150. The rear panel 142 angles away from the mid panel 141 as it extends away from the bottom end 150. Each one of the front panel 140, mid panel 141, and rear panel 142 has a generally planar construction.

(19) The air freshener holder 130 includes a front compartment 143 that is defined between the front panel 140 and the mid panel 141. The front compartment 143 of the present embodiment is uniformly sized and has a generally flat-shaped, slot-shaped or planar construction that is suited to house a generally flat air freshener cartridge. This type of air freshener fits snugly within the front compartment 143 and resists excessive movement in response to airflow passing through the air freshener, which could cause a disturbing rattle. The air freshener holder 130 further includes a rear compartment 144 that is defined between the mid panel 141 and the rear panel 142. The rear compartment 144 of the present embodiment has a generally wedge-shaped construction that is comparatively larger than the front compartment 143. The rear compartment 144 becomes progressively wider moving in the direction from the bottom end 150 to the open top 131. The construction and geometry of the rear compartment 144 are suited to house a bulky or non-planar air freshener cartridge. The wedge-shaped rear compartment 144 can accommodate air freshener cartridges of varying sizes. The mid panel 141 functions as a partition or divider to create the front compartment 143 and the rear compartment 144.

(20) As shown in FIG. 3, the air freshener holder 130 is provided with a pair of attachment features 151 in the pair of sidewalls 148 and 149 proximate the bottom end 150 of the air freshener holder 130. The attachment features 151 define a pivoting axis of the air freshener holder 130. As shown in the figure, in one exemplary form the attachment features 151 are constituted by a pair of indents formed in sidewalls 148 and 149 that lock or snap into place with corresponding complementary projections that are formed in the front section 122 of the body 120. This interlocking, snap-fit arrangement enables the air freshener holder 130 to pivot or rotate within the front section 122 about the pivoting axis defined by the attachment features 151. The air freshener holder 130 can be removed by releasing or disengaging the snap-fit connection of the indents and complementary projections. During assembly, the air freshener holder 130 is maneuvered into the interior cavity 160 of the front section 122 through the air outlet end 138 and snapped into place via the attachment features 151 (for which the air freshener holder 130 and/or the front section 122 can be slightly deformable and resilient to provide the snapping effect). As shown in FIG. 4, in its assembled location, the air freshener holder 130 can pivotably rest on the lower end 172 of the outer peripheral sidewall 170 of the front section 122. The air freshener holder 130 includes a projection or handle 152 extending from an upper end of front panel 140 to facilitate user movement of air freshener holder 130 through its pivoting orientations.

(21) The air freshener holder 130 is provided with various openings to facilitate the passage of airflow through the air freshener holder 130 and the air freshener cartridge(s) housed in the air freshener holder 130. The airflow occurs successively through the rear panel 142, the mid panel 141, and the front panel 140. In particular, in order to facilitate the communication of air through the air freshener holder 130, the rear panel 142 is provided with a set of slits or openings 147; the mid panel 141 is provided with a set of slits or openings 146; and the front panel 140 is provided with a set of slits or openings 145, as shown in FIGS. 3 through 5. Any type or arrangement or geometry of slits or openings can be used.

(22) The air freshener module 100 further includes a user-operable closure mechanism 132 that controllably regulates the amount of air that is admitted into the interior cavity 160 of the front section 122 for odorizing. The interior cavity 160 of the front section 122 is occupied by the air freshener holder 130 and the air freshener cartridge that it houses (not shown), and so the closure mechanism 132 regulates the amount of air that is odorized by the air freshener contained in air freshener holder 130.

(23) The closure mechanism 132 of the present embodiment is provided in the form of a planar, generally circular, disc-shaped member or throttle plate that is rotatably attached to the body 120 at some point along the air passageway 166, and is rotatable around an axis generally orthogonal to the longitudinal axis of the body 120, to block or unblock air passing through the air passageway 166. For instance, as best shown in FIGS. 3 and 4, the closure mechanism 132 of the present embodiment is located in the interior cavity 162 of the mid section 124. The closure mechanism 132 is generally the same size as the transverse cross-sectional area of the interior cavity 162 of the mid section 124. In this manner, when the closure mechanism 132 is oriented so that its main surface area is generally perpendicular to the longitudinal axis of the body 120, as shown in FIG. 4, the closure mechanism 132 substantially blocks the passage of any airflow entering via the air inlet end 136.

(24) The closure mechanism 132 is fitted with a pair of fastener or attachment projections 134 that are diametrically opposed to one another. During assembly, the closure mechanism 132 is maneuvered into the interior cavity 162 of the mid section 124 and locked into place. In particular, the attachment projections 134 are snap-fit into corresponding complementary indents 125 formed in an axial surface of the mid section 124. This snap-fit connection secures or locks the closure mechanism 132 into an upright pivotable configuration within the interior cavity 162. When the closure mechanism 132 is so assembled into the air freshener module 100, the diametrical transverse axis that extends between the pair of attachment projections 134 of closure mechanism 132 defines a pivot axis for closure mechanism 132. This pivot axis is generally orthogonal to the longitudinal axis of body 120. The air freshener module 100 includes a cable assembly, articulated rod set, or other means for connecting the control switch 104 of air control panel 102 to the closure mechanism 132 in order to permit the user to implement user-selective control of the pivoting movement of closure mechanism 132. In this manner, the user can select the rotational orientation of closure mechanism 132 and so regulate the airflow communicated through the air freshener module 100. Any means known to those skilled in the art can be used to establish this control feature of closure mechanism 132.

(25) The illustrations of FIGS. 4 and 5 depict different operating states or modes of operation of the air freshener module 100. On one hand, FIG. 4 depicts a mode of operation in which the air freshener holder 130 is positioned in an open configuration. This open configuration is suitable for loading the air freshener holder 130 with an air freshener cartridge as part of a preliminary set-up procedure. The air freshener holder 130 can be loaded by placing a single flat cartridge in the front compartment 143, a single bulkier cartridge in the rear compartment 144, or a combination thereof, to name a few examples. In turn, FIG. 5 depicts a mode of operation in which the air freshener holder 130 is positioned in a closed configuration. This closed configuration is suitable for enabling conveyed air moving through the air freshener module 100 to pass through the air freshener holder 130, where the airflow is odorized before exiting into the vehicle cabin.

(26) Referring to FIG. 4, the air freshener holder 130 is pivoted outwards away from the body 120 of air freshener module 100, allowing the user to access both the front compartment 143 and the rear compartment 144 of air freshener holder 130. Depending on the application and the deodorizing requirements, the user inserts or loads the appropriate air freshener cartridge into either the front compartment 143 or the rear compartment 144 of air freshener holder 130. In this cartridge loading mode, there is no need for the communication of airflow through the air freshener module 100. Accordingly, as shown, the closure mechanism 132 is selectively moved or rotated by the user so that the closure mechanism 132 is positioned in a substantially orthogonal orientation to the longitudinal axis of the body 120 of the air freshener module 100. In this closed position, the closure mechanism 132 substantially blocks or restricts the airflow 114 entering via the air inlet end 136 from proceeding past the closure mechanism 132. After the cartridge loading step is complete, the loaded air freshener holder 130 can be pivoted fully back into the module 130 so that it adopts the closed configuration of FIG. 5.

(27) Referring to FIG. 5, the air freshener holder 130 is depicted in a closed state in which the open, wide-mouth top 131 of the air freshener holder 130 is arranged within the interior cavity 160 of the front section 122, and the front panel 140 of the air freshener holder 130 is closing the air outlet end 138 except for the openings 145. In this closed state, the front panel 140 of air freshener holder 130 is generally flush with the air outlet end 138 of body 120. Additionally, in its operative resting configuration, the air freshener holder 130 is positioned so that its rear panel 142 rests or abuts against an upper portion of the back sidewall 173 of the front section 122, as shown. This abutment helps stabilize the location and positioning of air freshener holder 130. The throttle plate 132 is selectively moved or rotated by the user so that the throttle plate 132 is positioned in a substantially parallel orientation to the longitudinal axis of the body 120, as shown. In this open position, the closure mechanism 132 permits the airflow 114 entering via the air inlet end 136 to continue into the interior cavity 160 of the front section 122 and pass through the air freshener holder 130, as shown.

(28) During operation, fresh airflow 114 conveyed by air tube 112 enters the air freshener module 100 via the air inlet end 136 at the rear section 126. The open throttle plate 132 allows the incoming airflow 114 to continue through the interior cavity 162 of the mid section 124 and proceed into the interior cavity 164 of the front section 122. The airflow 114 travels through the air freshener cartridge(s) (not shown) loaded into the air freshener holder 130 and emerges or exits from the air freshener module 100 via the air outlet end 138, and more specifically, through the openings 145 of the front panel 140. During its passage through the air freshener holder 130, the airflow 114 becomes odorized via its contact with the air freshener cartridge(s). The odorized airflow 114 exits via the front panel openings 145 into the vehicle cabin environment and deodorizes the cabin air space.

(29) A vehicle air freshener module 200 is presented in various configurations in the illustrations of FIGS. 6 and 7, according to a second embodiment of the invention. Like features of the air freshener module 200 and the air freshener module 100 of FIGS. 1 through 5 are numbered the same except preceded by the numeral 2. The air freshener module 200 includes a sliding-type air freshener receptacle or holder 280, compared to the pivot-type air freshener receptacle or holder 130 of air freshener module 100 shown in FIGS. 1 through 5.

(30) The air freshener holder 280 is provided in the form of a slidable drawer-type structure having a front panel 282, a divider partition or mid panel 284, a rear panel 286, and a pair of sidewalls 287 and 288. The front panel 282 defines the front end of air freshener holder 280, while the rear panel 286 defines the back end of air freshener holder 280. The front panel 282 is disposed in a spaced-apart, opposing, generally parallel relationship with the mid panel 284. The rear panel 286 is disposed in a spaced-apart, opposing, generally parallel relationship with the mid panel 284. The air freshener holder 280 has an open, wide-mouth top 290 and a flat planar bottom end 291 that is coextensive with the top 290. The air freshener holder 280 is open at the top 290 and closed at the bottom end 291. Each one of the front panel 282, mid panel 284, and rear panel 286 has a generally planar construction.

(31) The air freshener holder 280 includes a front cartridge slot or compartment 292 that is defined between the front panel 282 and the mid panel 284. The front compartment 292 is uniformly sized and has a generally flat-shaped or planar construction that is suited to house a generally flat air freshener cartridge. The air freshener holder 280 further includes a rear cartridge slot or compartment 293 that is defined between the mid panel 284 and the rear panel 286. The rear compartment 293 has a generally rectangular prism construction that is comparatively larger than the front compartment 292. The rear compartment 293 is suited to house a bulky air freshener cartridge. The rear compartment 293 can accommodate air freshener cartridges of varying sizes. The mid panel 284 functions as a partition or divider to create the front cartridge slot 292 and the rear cartridge slot 293.

(32) The air freshener holder 280 is slidably located within the cavity 260 of the front section 222. The air freshener holder 280 is supported at its bottom end 291 by resting on the lower end 272 of the outer peripheral sidewall 270 of front section 222. The air freshener holder 280 can be shifted between various positions by appropriately displacing or sliding the drawer-type air freshener holder 280. The illustration of FIG. 7 depicts an open, cartridge-loading access configuration in which the air freshener holder 280 is withdrawn from air freshener module 200 so that an air freshener cartridge can be loaded into (or removed from) the front cartridge slot 292 or rear cartridge slot 293. The outer peripheral sidewall 270 of front section 222 is provided with a radially extending flange 295 at a front end to serve as a stop feature or abutment that limits the outward travel of air freshener holder 280 and prevents the air freshener holder 280 from being accidentally pulled completely out of air freshener module 200.

(33) The air freshener holder 280 is provided with various openings to facilitate the passage of airflow through the air freshener holder 280 and the air freshener cartridge housed in the air freshener holder 280. The airflow occurs successively through the rear panel 286, the mid panel 284, and the front panel 282. In particular, in order to facilitate the communication of air through the air freshener holder 280, the rear panel 286 is provided with an opening 247; the mid panel 284 is provided with a set of slits or openings 246; and the front panel 282 is provided with a set of slits or openings 245. Any type or arrangement of slits or openings can be used.

(34) During operation, the air freshener holder 280 is located within the cavity 260 of the front section 222. The odorizing of the incoming airflow 114 occurs in a similar manner to the operation of the air freshener module 100 of FIGS. 1 through 5.

(35) The above-described embodiments are merely exemplary illustrations of implementations set forth for a clear understanding of the principles of the invention. Many variations, combinations, modifications or equivalents may be substituted for elements thereof without departing from the scope of the invention. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all the embodiments falling within the scope of the appended claims.
