FIG. 1 illustrates a range hood 10 according to one embodiment of the invention. The range hood 10 can include a flue 12, a housing 13, a lighting and control unit 14, a louver assembly 16, a front panel 18, and a palette 24.
The flue 12 can be coupled to the housing 13 in any suitable manner. In some embodiments, the flue 12 includes one front panel and two side panels. The flue 12 can be coupled to a wall, a ceiling, ducting, and/or recirculation components in any suitable manner. Additional ducting or recirculation components (as shown in FIG. 10) can be positioned within an interior portion of the flue 12. The flue 12 can be at least partially constructed of a decorative material, such as stainless steel, painted metal, copper, etc.
The housing 13 can hang on a wall surface. A rear panel of the housing 13 can be coupled to the wall in any suitable manner. A fan 19 (as shown in FIG. 10) can be positioned in an upper portion of the housing 13 above the louver assembly 16. The fan 19 can be mounted with one or more supports to the rear panel of the housing 13. The housing 13 can be coupled to the lighting and control unit 14, the louver assembly 16, and the palette 24. The housing 13 can include one or more sets of vents 22, such as several sets of vents 22 positioned across a front, top portion of the housing 13.
In some embodiments, the housing 13 can include a front panel 18 in the form of a recessed portion on a front side of the housing 13. The front panel 18 can receive the palette 24, such as a decorative panel constructed of ceramic tile, glass, stainless steel, copper, a solid surfacing material (e.g., Corian® manufactured by E. I. du Pont de Nemours and Company), etc. In some embodiments, the palette 24 can be attached to the front panel 18 with small tabs on the bottom of the palette 24 that engage with slots that can be located in a body portion of the front panel 18 and/or the housing 13. Once the bottom tabs are in place, the palette 24 can be rotated upward. As shown in FIG. 10, one or more latches 27 (e.g., a spring-loaded latch) can be positioned on a top portion of the front panel 18. The latch 27 can engage with slots on a top portion of the palette 24. When the palette 24 is rotated up completely, the latch 27 can engage the palette 24 and snap the palette 24 in place. The palette 24 can also be coupled to the front panel 18 with one or more leaf springs 26 (as shown in FIGS. 10 and 11) that can accommodate various thicknesses of materials. The leaf springs 26 can also apply outward pressure to keep the palette 24 from repeatedly contacting the front panel 18 and making noise. In some embodiments, the palette 26 can be removed by sliding a thin piece of material (e.g., a credit card) in between a top edge of the palette 26 and the front panel 18 to disengage the latch 27. The top portion of the palette 26 can then rotate freely and can be lifted from the bottom tabs and removed.
The lighting and control unit 14 can include a first face 28 that can lie in substantially the same plane as the palette 24 and be substantially flush with edges of the housing 13 when the lighting and control unit 14 is in a closed position, as shown in FIGS. 1-4 and 10. As shown in FIGS. 5-9 and 11, the lighting and control unit 14 can be rotated upward to reveal a second face 30 with a user interface 32 and a third face 34 with one or more task lights 36 (as shown in FIG. 8). The task lights 36 can be recessed lights. The user interface 32 can include any one or more of the following: one or more controls, one or more indicator lights, one or more timers, a digital clock, etc. The controls can be used to control the fan and/or the task lights 36. In some embodiments, the first face 28, the second face 30, and the third face 34 can each have a rectangular shape. In one embodiment, as shown in FIG. 11, side edges of the second face 30 can be rounded and the third face 34 can be recessed within the rounded edges of the second face 30.
The lighting and control unit 14 can be rotatably coupled to the housing 13 in any suitable manner. In some embodiments, the lighting and control unit 14 coupled to a motor 38 positioned within the housing 13. The motor 38 can rotate the first face 28 of the lighting and control unit 14 outward when in the user interface 32 is in use and rotate the first face 28 inward when the user interface 32 is not in use. For example, a user can push a button or a portion of the first face 28 to open or close the motorized lighting and control unit 14. Alternatively or additionally, the lighting and control unit 14 can be biased by springs or the like to open or close when a button or a portion of the first face 28 is pushed.
The louver assembly 16 can include a filter 40 through which the fan 19 positioned within the housing 13 can draw the cooking effluent. The louver assembly 16 can include any suitable number and configuration of louvers 42. In some embodiments, the louvers 42 can be coupled to a motor 44 (as shown in FIG. 9). The motor 44 can be secured to an inside panel of the louver assembly 16. The motor 44 can be used to control the louvers 42 in order to open the louvers 42 and capture cooking effluent when the range hood is in use. The motor 44 can close the louvers 42 when the range hood in not in use. In some embodiments, the motor 44 can open the louvers 42 at various degrees depending on the speed of the fan 19 in order to provide a substantially constant velocity for the capture of cooking effluent.
In some embodiments, the entire louver assembly 16 or a portion of the louver assembly 16 can rotate downward in order to gain access to the filter 40, which can be cleaned or removed and replaced. The louver assembly 16 can also be rotated downward to service the electronics of the user interface 32 and/or to service the motors 38 and 44. The louver assembly 16 can include a release latch 46, as shown in FIG. 9, that can allow a user to quickly release the louver assembly 16 from the housing 13. The louver assembly 16 can be coupled to the housing 13 by a hinge 48, as shown in FIG. 9. The louver assembly 16 can include one or more springs 50 that can prevent the louver assembly 16 from falling open against the wall to which the housing 13 is mounted. In other embodiments, the louver assembly 16 can rotate upward to gain access to the filter 40 and the motors 38 and 44, and the louver assembly 16 can be held open by a suitable bracket.
