VENT ASSEMBLY FOR AUTOMOBILES HAVING SEPARATE GRILL
UNIT AND CONTAINER COMPARTMENT
Technical Field
The present invention relates, in general, to vent assemblies for automobiles each of which has a separate grill unit and a container compartment and, more particularly, to a vent assembly for automobiles, which has a container compartment being selectively ejected or retracted by a drive means from or into a housing installed at a predetermined portion of a dashboard of an automobile, and a grill unit provided at a front end of the container compartment to be openable outward or inward relative to the housing by an additional drive means, thus allowing a user to easily contain a desired material, such as an aromatic, germicide or deodorizer, in the grill unit, and simply change the material with a new one, thus pleasantly maintaining the atmosphere of a passenger compartment of the automobile, and allowing the user to easily clean the grill unit and the interior of the housing, so that the vent assembly blows cool or hot air of a fresh and clean state into the passenger compartment, thus preventing the user or passengers from contracting several respiratory diseases.
Background Art
Generally, automobiles have been used as a means of conveyance or transport, in which a liquid energy source that is a fuel is evaporated, and the evaporated fuel gas is mixed with air and, thereafter, an engine of the automobile draws the mixed fuel gas into therein and executes mixed fuel gas compression, combustion and combustion gas exhaust operations to generate a driving force, so that the automobile can quickly move any distance using the driving force generated by the above-mentioned operations.
Such automobiles are provided with air conditioning apparatuses, such as heaters or air conditioners, for discharging impure air from the passenger
compartment to the atmosphere and controlling a temperature of the passenger compartment, thus appropriately conditioning the air in the passenger compartment while driving the automobile. Fresh air fed from such an air conditioning apparatus is blown into the passenger compartment through a blowing duct installed at a dashboard with a vent assembly having a grillwork provided at a front of the blowing duct.
In a conventional vent assembly for automobiles, a grillwork holder, installed at the dashboard, holds the grillwork to discharge into the passenger compartment the air of a low or high temperature passing through the blowing duct. Therefore, when it is desired to change the air blowing direction of the grillwork, a plurality of horizontal or vertical blades, provided at the grillwork, are manually tilted upward, downward, leftward or rightward within the fixed grillwork holder, thus appropriately controlling a direction of the air discharged from the vent assembly into the passenger compartment. However, when conditioning the air of the, passenger compartment through the conventional vent assembly, external dusts and internal dusts of the automobile are drawn along with the air into the air conditioning apparatus through an air inlet of the air conditioning apparatus during an operation of the air conditioning apparatus, thus fine dusts are deposited in the blowing duct and on the grillwork because the dusts are discharged along with the air into the passenger compartment. Therefore, the deposited fine dusts, discharged along with the cool or hot air into the passenger compartment through the grillwork of the conventional vent assembly, may cause several respiratory diseases as well as be the source of odor and uncleanliness. To solve the problem of the above-mentioned uncleanliness, the user must clean the interior of the vent assembly or install an air filter or a bacterial filter at a position around the vent assembly after removing the grillwork from the blowing duct. However, because the conventional vent assembly is produced to be impossible to remove the grillwork from the blowing duct, the conventional vent assembly is problematic in that the cleaning of the interior thereof or the installation and a change of the filter are very difficult.
In the meantime, to solve the problem of the above-mentioned odor, air quality enhancing agents, such as aromatics, germicides, and/or deodorizers are laid on the top wall of the dashboard or the rear shelf provided in back of the rear seats inside the passenger compartment, or are attached to the front of the grillwork such that air laden with components of the air quality enhancing agents circulates in the passenger compartment. However, such installation of the air quality enhancing agents makes the interior of the passenger compartment messy, as well as hindering the driving of a driver.
In an effort to overcome the problems experienced in the conventional vent assembly, there was proposed and has been used an interior vent nozzle for air conditioning apparatuses of automobiles in Japanese Utility Model Laid-open Publication No. Sho. 61-137,012. The vent nozzle, which corresponds to a grill unit with a grillwork, is removably installed in a housing fixedly set in the dashboard of an automobile such that the grill unit with the grillwork is completely removed from the housing by pulling the grill unit from the housing when desired. That is, this grill unit has a detachable structure, which allows a user to install or remove the grill unit with the grillwork in or from the housing provided in the dashboard. However, due to such a detachable structure, the vent nozzle generates noises upsetting passengers around the grill unit when the automobile runs at a speed with substantial vibrations. In addition, when the grill unit is repeatedly removed and installed from or in the housing, the assembling parts of both the grill unit and the housing may be damaged, broken or lost.
To solve the above-mentioned problems experienced in the conventional vent nozzle, vent assemblies for automobiles having drawer-type grill units were proposed in Korean Utility Model Registration NO. 297258 and 297260 ( Filed: November, 26. 2002 ) which were applied by the inventor of the present invention and have been registered.
The vent assembly proposed in Korean Utility Model Registration NO. 297258 includes a grill unit, a housing installed at a vent channel of a dashboard, and a drive means. The grill unit includes a grillwork holder which has at a
front thereof a grillwork, and a container compartment which is provided at a back of the grillwork holder and has an air inlet opening, with movable rails arranged along outer surfaces of both sidewalls of the container compartment.
The grill unit is ejected from or retracted into the housing along fixed rails of the housing within a predetermined range by the drive means. Two horizontal racks are arranged along upper or lower ends of both sidewalls of the container compartment so as to respectively engage with two pinion gears provided at both ends of a drive shaft of the drive means in which a first transmission gear of an intermediate gear assembly engages with a drive gear of a reversible motor, and a driven gear is mounted to an end of the drive shaft and engages with a second transmission gear of the intermediate gear assembly.
In the meantime, the vent assembly proposed in Korean Utility Model Registration NO. 297260 includes a grill unit, a housing installed at a vent channel of a dashboard, and a drive means. The grill unit includes a grillwork holder which has at a front thereof a grillwork, and a container compartment which is provided at a back of the grillwork holder and has an air inlet opening, with movable rails arranged along outer surfaces of both sidewalls of the container compartment. The grill unit is ejected from or retracted into the housing along fixed rails of the housing within a predetermined range by the drive means. The container compartment has a stopper at a rear end thereof to engage with and disengage from a push button switch installed in the housing, and has a drive roll at a bottom thereof, with a drive spring being connected at a first end thereof to the drive roll to be wound around and unwound from the drive roll. A horizontal rack is provided along an upper surface of one of the movable rails which are arranged along both sidewalls of the container compartment, to engage with a reduction gear installed in the housing. The housing has a drive opening on a bottom thereof so that the drive roll is moved forward and backward along the drive opening, with a second end of the drive spring being connected to an outer surface of a front portion of the housing. The above-mentioned conventional vent assemblies having the drawer- type grill units each allow a user to eject the grill unit from the housing within a
predetermined range to be not completely removed from the housing, so as to solve the problems of loss or damage to the assembling parts of the vent assemblies and to easily remove impurities which are deposited and caught in the grill unit and in the interior of the housing. Therefore, the vent assemblies blow cool or hot air of a fresh and clean state into the passenger compartment.
However, the grillwork holder having a predetermined height is integrally provided at a front portion of the grill unit, thus the conventional vent assemblies cause inconvenience to the user when it is desired to clean the grill unit and the interior of the housing or to contain a desired material, such as an aromatic, in the container compartment.

Best Mode for Carrying Out the Invention
Reference should now be made to the drawings, in which the same reference numerals are used throughout the different drawings to designate the same or similar components. FIG. 1 is an exploded perspective view of a vent assembly for automobiles according to a first embodiment of the present invention. FIG. 2 is a plan sectional view showing a construction of the vent assembly of FIG. 1. FIGS. 3 A through 3C are longitudinal sectional views showing an operation of the vent assembly of FIG. 1. As shown in FIGS. 1 through 3C, the vent assembly according to the first embodiment of the present invention includes a housing 1, a container compartment 2, a drive means 3, and a grill unit 4.
The housing 1 supports the grill unit 4 to determine a blowing direction of cool or hot air which is discharged toward a front of a dashboard from an air conditioning apparatus through a blowing duct which is coupled to an outlet of the air conditioning apparatus. The housing 1 has a space defined above the container compartment 2 therein, so that air quality enhancing agents, such as aromatics, germicides, and/or deodorizers, are contained in the space to remove odor. To form the above-mentioned housing 1, the housing 1 is installed in the dashboard and has at an inside end thereof a square-shaped opening which is coupled to the blowing duct. The housing 1 further has a rim 11 which is integrally formed around an outside end of the housing 1 so as to prevent the housing 1 from being completely inserted into the dashboard.
Two fixed rails 12 are respectively oppositely provided along inner surfaces of both sidewalls of the housing 1 in longitudinal directions. The housing 1 further has at a predetermined portion on one of the sidewalls thereof a mounting hole 13. , A first drive gear 31, which will be described later herein, is mounted to the mounting hole 13 so that the first drive gear 31 is placed in the housing 1.
The container compartment 2 slides frontward or rearward along the fixed rails 12 of the housing 1 by the drive means 3, so that the container compartment 2 is ejected from or retracted into the housing 1. The container compartment 2 includes a container compartment body 20 having a plate-type bottom with opposite sidewalls having a predetermined height and is open at front and rear ends thereof. Two movable rails 21 are respectively provided on outer surfaces of the sidewalls of the container compartment body 20 to engage with the two fixed rails 13 of the sidewalls of the housing 1 and slide along the fixed rails 12 of the housing 1. A horizontal rack 22 is formed along an upper surface of one of the two movable rails 21.
The container compartment 2 further includes a plurality of locking pieces 23 which are provided on predetermined portions of an upper surface of a bottom of the container compartment body 20 to removably mount a box-type container unit 24 containing therein the air quality enhancing agents, such as the aromatics and etc., to the plurality of locking pieces 23.
The plurality of locking pieces 23 are symmetrically formed on the upper surface of the bottom of the container compartment body 20. However, the locking piece 23 may have a screw-type shape, thus mounting the container unit 24 to the screw-type locking piece 23. The container compartment 2 further includes an air inlet opening 25 which has a predetermined area and is provided at a rear wall of the container compartment body 20.
The vent assembly according to the first embodiment of the present invention has the drive means 3, so as to simultaneously or selectively execute an opening or closing motion of the grill unit 4 and an ejecting or retracting motion of the container compartment 2 relative to the housing 1.
As shown in FIGS. 1 through 3C, the drive means 3 according to the first embodiment includes a first motor 30 which is provided on the sidewall of the housing 1 at an upper portion of a front part of the sidewall of the housing 1 and has a first drive' gear 31, a first pinion gear 32 which is provided on an inner surface of the sidewall of the housing 1, and an idle gear 33 engaging with both the first drive gear 31 and the first pinion gear 32. The drive means 3 further includes the horizontal rack 22 which is arranged along an outer surface of the sidewall of the container compartment 2 and engages with the first pinion gear
32. The drive means 3 further includes a hinge shaft 41 which is provided on an upper portion of a sidewall of the grill unit 4, with a driven gear 34 being mounted to the hinge shaft 41 and engaging with the first drive gear31. Due to the above-mentioned construction of the drive means 3, the container compartment 2 is ejected forward from the housing 1 by a rotation of the first motor 30.
The grill unit 4 is rotated by the rotation of the first motor 30 inward and upward around the hinge shaft 41 which is coupled to the upper portion of the front part of the sidewall of the housing 1, thus opening the front of the housing 1.
The grill unit 4 ordinary changes a blowing direction of cool or hot air discharged from the vent assembly into the passenger compartment. When it is desired to clean the interior of the housing 1 or change the air quality enhancing agent, such as an aromatic, with a new one, the grill unit 4 is opened at the front of the housing to easily execute the above-mentioned cleaning or changing operation. At this time, the grill unit 4 does not interfere with the container compartment 2 while the container compartment 2 is ejected from or retracted into the housing 1. The grill unit 4 has a square-shaped space therein. A grillwork 40, which comprises a plurality of blades, is provided in the square- shaped space defined in the grill unit 4 to be manually tilted upward, downward, leftward or rightward by manipulating a dial which is provided in the square- shaped space of the grill unit 4 to operate in conjunction with the blades of the grillwork 40. The grill unit 4 has the hinge shaft 41 which is provided on the
upper portion of the sidewall of the grill unit 4 and is inserted into the housing 1 through a hinge hole 14 which is provided on a predetermined portion of the sidewall of the housing 1.
The grill unit 4 further has a seating slot 42 which is formed on an upper surface of the grill unit 4 so as to seat an air filter 5 in the grill unit 4.
Next, the operation and effect of the vent assembly according to the first embodiment of the present invention will be described herein below with reference to FIGS. 3A through 3C.
When the air conditioning apparatus (not shown), such as a heater or an air conditioner, is operated while the container compartment 2 is placed in the housing 1 as shown in FIG. 3A, the cool or hot air discharged from the outlet of the air conditioning apparatus passes through the blowing duct (not shown) which is coupled to the inside end of the housing 1. Thereafter, the cool or hot air is blown into the passenger compartment through the housing 1, the container compartment 2, and the grillwork 40 which is provided in the grill unit 4.
At this time, the plurality of blades of the grillwork 40 are manually tilted at predetermined angles by manipulating the dial which is provided in the grill unit 4, so that the cool or hot air is discharged into the passenger compartment in a desired direction. When it is desired to clean the interior of the housing 1 or to change the air quality enhancing agent, such as the aromatic and etc., contained in the container unit 24 of the container compartment 2, with a new one, a user turns on the power switch (not shown), so that a constant current is supplied under the control of the control unit (not shown) to the first motor 30, thus the first drive gear 31 of the first motor 30 is rotated clockwise.
When the first drive gear 31 is rotated clockwise, the idle gear 33, engaging with the first drive gear 31, is simultaneously rotated counterclockwise, and, simultaneously, the first pinion gear 32, engaging with the idle gear 33, is rotated clockwise. Thus, the movable rails 21 of the container compartment 2, having the horizontal rack 22 engaging with the first pinion gear 32, slide frontward along the fixed rails 13 of the housing 1, so that the ejecting motion of
the container compartment 2 with the movable rails 23 relative to the housing 1 starts.
Simultaneously, the driven gear 34, engaging with the first drive gear 31, is rotated counterclockwise, so that the grill unit 4 is rotated counterclockwise ( in a direction of the interior of the housing 1 ) around the hinge shaft 41, thus opening the front of the housing 1, as shown in FIGS. 3B and 3C.
In the above-mentioned state in that the container compartment 2 is exposed to the outside and the grill unit 4 is opened at the front of the housing 1, the user changes the air filter 5, which is seated in the grill unit 4, and/or the air quality enhancing agent, which is contained in the container unit 24 of the container compartment 2, with new ones. After the process of cleaning the housing 1 or changing the air quality enhancing agent or the air filter 5 is finished, the user turns on the power switch (not shown), thus the first drive gear 31 is rotated counterclockwise and, simultaneously, the idle gear 33, the driven gear 34 and the first pinion gear 32 are rotated in directions opposite to the ejection operation. Thus, the container compartment 2, which has been ejected from the housing 1, is retracted into the housing 1, and the grill unit 4, which has been opened at the front of the housing 1, closes the front of the housing 1, so that the vent assembly accomplishes a state to discharge the cool or hot air into the passenger compartment.
In the vent assembly of the first embodiment of the present invention, the driven gear 34, being mounted to the hinge shaft 41 which is provided on the upper portion of the sidewall of the grill unit 4, engages with the first drive gear 31 of the first motor 30, and, simultaneously, the horizontal rack 22 of the container compartment 2 is connected to the first drive gear 31 via the idle gear
33 and the pinion gear 32, so that the opening or closing motion of the grill unit 4 and the ejecting or retracting motion of the container compartment 2 relative to the housing 1 are simultaneously executed by the rotation of the first drive gear 31 of the first motor 30. However, in a vent assembly for automobiles according to a second embodiment of the present invention, as shown in FIGS. 4 through
5C, a first motor 30 and a second motor 35 may be used as the drive means 3.
