- As shown and described in the following description in
FIGS. 1 , 2 a-2 e, 3 a-3 f, 4 a-4 b, some embodiments of the invention can be installed adjacent to a cooking area (e.g., in a kitchen). For example, in some embodiments, the range hood systems as described below and illustrated inFIGS. 1 , 2 a-2 e, 3 a-3 f, 4 a-4 b, can be installed immediately adjacent to, or above a cook top or range top, or within an alternative environment. Accordingly, although the description herein includes details of the range hood system installed in a kitchen area as described, this description is not intended to limit the scope of this disclosure to kitchen or cooking-related applications. Moreover, as described in further detail below, the range hood systems shown inFIGS. 1 , 2 a-2 e, 3 a-3 f, and 4 a-4 b can comprise a plurality of different configurations. - In some embodiments, in order to exhaust at least a portion of a cooking effluent and other fluids produced during a cooking episode, a ventilation assembly can be activated to remove steam, and other gases and odors from the cooking area above the range top and areas immediately adjacent to the range top. For example, in some embodiments of the invention, the range hood systems shown in
FIGS. 1 , 2 a-2 e, 3 a-3 f, and 4 a-4 b can include a ventilation system comprising an fan, and filter system coupled within a housing that includes at least one inlet. Some other embodiments may include a louver system, coupled to the fan and ducting system which is coupled to the housing. At least a portion of the fluid can be moved away from the range top and immediately adjacent areas and pulled through the ventilation system via one or more fluid inlets. Moreover, in some embodiments, the ventilation system can include one ormore filters 41 positioned substantially in the ducting system, coupled to the fan. In some embodiments, the ventilation system includes at least one duct (i.e. at least one fluid outlet) coupled to a location external to range hood that can direct the exhausted effluent to a desired location (e.g., out of the structure, out of the local environment, or back out of the range hood following filtration to remove odors and/or particulates, etc.). - In some embodiments, the range hood systems shown in
FIGS. 1 , 2 a-2 e, 3 a-3 f, and 4 a-4 b can comprise ahousing 13 including afirst surface 15 including auser interface 11. Some embodiments of the invention include at least oneuser interface 11 comprising one or more switches, buttons or other control features located substantially on thefirst surface 15. In some embodiments, the switches or buttons can comprise the ability to control a ventilation assembly (i.e., control activation and deactivation and/or multiple operational speeds of the ventilation assembly), or an illumination source, and can also provide feedback to the user. For example, in some embodiments where the ventilation system comprises afilter 41, theuser interface 11 can comprise one or more indicators that can provide an indication of whether thefilter 41 needs to be cleaned and/or replaced. Moreover, in some embodiments, theuser interface 11 can also include an indicator reflecting the operation of an over-heating protection system. In some embodiments, one or more components designed to transfer user-directed actions to functional changes in therange hood system 10 can comprise rear-mounted capacitive control buttons or switches. In other embodiments, electromechanical switches, buttons, such as ‘push-buttons’, toggles, or dials can be used. In some embodiments, at least one or more switches or buttons can be actuated by a user. In some embodiments, a user can actuate at least one or more switches or buttons by applying a force to the switch or button. In some other embodiments, a user can actuate at least one or more switch or buttons by applying a force to at least some partial region of theuser interface 11. In some other embodiments, a user can actuate at least one or more switch or buttons by touching at least some partial region of theuser interface 11. - In some embodiments of the range hood systems shown in
FIGS. 1 , 2 a-2 e, 3 a-3 f, and 4 a-4 b, auser interface 11 is coupled with at least one control system for controlling and monitoring various operations of the range hood (not shown). In some embodiments, theuser interface 11 is coupled with at least one monitoring system to provide information on at least one functional status of at least one component of the range hood (not shown). In some embodiments, theuser interface 11 is coupled with at least one sensor (not shown) to provide information on the operational status of at least one component of therange hood system 10. For example, as shown inFIG. 1 , therange hood system 10 can comprise afan switch 44 and alight switch 46. Furthermore, in some embodiments, therange hood system 10 can comprise one or more visual indicators can be included in theuser interface 11 to communicate to the user the status of one or more components of therange hood system 10 may change state. In some embodiments of the invention for example, the control system (not shown) can be coupled to an illumination source, coupled within a third surface 19 (not shown), and further coupled to auser interface 11. For example as shown inFIG. 1 , the range hood can include auser interface 11. Furthermore, some other embodiments can include a device which can indicate the status of the range hood illumination source (i.e. whether or not the range hood illumination source is in an on or off state). For example as shown inFIG. 1 , therange hood system 10 can include auser interface 11 with at least one light emittingdevice 18. In some embodiments, the at least one light emittingdevice 18 can comprise a light-bulb or incandescent lamp, or a neon-bulb. In other embodiments, the at least one light emittingdevice 18 can be one or more light-emitting diodes. In other embodiments, the at least one light emittingdevice 18 can comprise some other visible light emitting device that can be capable of providing a visual signal to a user of the functional status of one or more components of therange hood system 10. For example as shown inFIG. 1 , thedisplay state 12 can comprise anlight emitting device 18 in an off-state 18 a, (i.e. no power is being supplied to thelight emitting device 18 and the device is not emitting light), or as shown indisplay state 20 comprising a light emitting device in an on-state 18 b (i.e. power is being supplied to thelight emitting device 18 and the device is emitting light). In some embodiments, thelight emitting device 18 may emit light with an identical, or substantially similar luminosity. In some other embodiments, thelight emitting device 18 may emit light at a luminosity, or intermittently (i.e. thelight emitting device 18 may cycle from an on to an off state. For example, as shown inFIG. 1 , thedisplay state 30 can comprise alight emitting device 35 that may emit light at intermittently to present a ‘blinking’ effect to a user. In some embodiments, thelight emitting device 35 may indicate to the user the need to change one ormore filters 41 in therange hood system 10. In some embodiments, when the total fan operation time reaches 30 hours, the filter change indicator (e.g. shown as a blinking light emittingdevice 35FIG. 1 ), will cycle on and off every two seconds. In some embodiments, thelight emitting device 35 will cycle on and off every two seconds regardless of the operating status of the fan. For example, in some embodiments, if a fan is active and thelight emitting device 18 is illuminated, but the fan operation time passes 30 hours, the light emitting device 18 (shown as light emitting device 35) will cycle on and off every two seconds to warn the user that the fan operation time has reached 30 hours, and therefore the recommended procedure is to renew thefilter 41. In some embodiments, the filter change indicator light emittingdevice 35 can be reset within the control system (not shown). For example, when the fan is off, and the filter change indicator is activated (i.e. light emittingdevice 35 is blinking), and the fan switch orbutton 44 is pressed and held for three seconds, the blinking filter change indicator light emittingdevice 35 will turn off, and a 30 hour filter change timer within the control system will be reset. In some other embodiments, for example when the fan is on, and the filter change indicator is activated (i.e. light emittingdevice 35 is blinking), and the fan switch orbutton 44 is pressed and held for three seconds, thelight emitting device 18 will stay illuminated (i.e. the blinking will cease), and the 30 hour filter change timer within the control system will be reset. In this embodiment, the fan speed will not be changed. - In some further embodiments of the invention, the
user interface 11 can comprise one or more icons associated with one or more switches or other user controls. For example, as shown inFIG. 1 , therange hood system 10 can comprise afan switch icon 14, and alight switch icon 16. In some embodiments, one or more of the switches or buttons can also comprise an icon. For example, as shown in therange hood system 10 inFIG. 1 , thefan switch 44 can comprise an icon that is substantially the same or similar to thefan switch icon 14, and thelight switch 46 can comprise an icon that is substantially the same or similar to thelight switch icon 16. In some embodiments, the one or more icons associated with the one or more switches or other user controls on theuser interface 11 may be substantially similar or the same.

In some embodiments, anaperture 32 can be included. As shown inFIG. 1 , in some embodiments, a plurality ofapertures 32 can be included. In some embodiments, theaperture 32 can provide an aesthetic appearance to therange hood system 10. In some other embodiments, theaperture 32 can provide a fluid connection between the exterior of therange hood system 10 and at least one internal component of therange hood system 10. In some embodiments, theaperture 32 may fluidly connect the exterior of therange hood system 10 and an internal ducting (not shown), and can be configured and arranged with the ducting and an internal filter (not shown) to provide a fluid relief pathway. In some other embodiments, theaperture 32 may fluidly connect the exterior of therange hood system 10 and at least one internal component of therange hood system 10 to allow air cooling of one or more components. As noted earlier, in some embodiments, therange hood system 10 can comprise one or more illumination sources (not shown). In some embodiments, the one or more illumination sources (not shown) can be configured and arranged to provide lighting to a range top surface. In some embodiments, the one or more illumination sources can be configured and arranged to provide lighting to an area immediately adjacent to the range top surface. - In some other embodiments, one or more visible light emitting components can be substantially integrated with the one or more buttons or switches. For example, as shown
FIGS. 2 a, 2 b, 2 c, 2 d, and 2 e therange hood systems user interface 11 positioned on afirst surface 15 of ahousing 13. In some embodiments, theuser interface 11 includes a plurality of buttons or switches configured and arranged to emit visible light. In some embodiments, a plurality of buttons or switches can incorporate a visible light emitting device for communicating the status of at least one component of the range hood. In some embodiments, at least a partial region of the button or switch is configured and arranged to emit light. In other embodiments, light is emitting from a region that surrounds at least a partial region of the button or switch. In some other embodiments, button or switch can include a light emitting component that can reside substantially behind at least a partial region of the button or switch. In some embodiments, the light emitting component can comprise a light emitting diode. In other embodiments, the light emitting component can comprise a light-bulb or incandescent lamp, or a neon-bulb. In some other embodiments, the light emitting device can comprise an electroluminescent source. In some other embodiments, the at least one light emitting component can comprise some other visible light emitting device that can be capable of providing a visual signal to a user of the functional condition or status of one or more components of therange hood system - For example, as shown in
FIG. 2 a indisplay state 222, when the fan or illumination source is not operational, the fan switch indicator is is not illuminated 223 a and the light switch indicator is not illuminated 225 a. Conversely when the fan is operational, the fan switch indicator is illuminated 223 b, as shown indisplay state 224. In some embodiments, when the fan is not operational, but theillumination source 205 is operational, the fan switch indicator is not illuminated 223 a, and the light switch indicator is illuminated 225 b, as shown in display state 226. In some other embodiments, thefan switch indicator 223 b may emit light intermittently to present a ‘blinking’ effect to a user (shown indisplay state 228 where thefan switch indicator 223 b is illuminated intermittently). In some embodiments, the ‘blinking’ effect to a user may indicate to the user the need to change one ormore filters 41 in therange hood system 200. In some further embodiments, for example as illustrated inFIG. 2 a. 228, when the fan has been operated for 30 hours,fan switch indicator 223 b is illuminated intermittently (e.g. 1 cycle every 2-seconds). This switch indicator will blink if the fan is in the on or off state. If the fan is off, and the filter change indication is activated, the indicator will blink at low luminosity. If the fan is on, and the filter change indication is activated, thefan switch indicator 223 b will blink with a luminosity related to the fan speed (i.e. low luminosity at low fan speed, and high low luminosity at high speed). When the fan is off, and the filter change indicator is activated (fan switch indicator 223 b is blinking), and thefan switch indicator 223 b is pressed and held for three seconds, the blinking will stop and illumination from thefan switch indicator 223 b will turn off (reverting tofan switch indicator 223 a as represented in display state 222), and the 30 hour timer will be reset. When the fan is on, and the filter change indicator is activated (fan switch indicator 223 b is blinking), and thefan switch indicator 223 b is pressed and held for three seconds, the blinking will stop and thefan switch indicator 223 b will stay illuminated, (a luminosity related to the fan speed). The 30 hour timer will be reset, and the fan speed will not be affected. - In some embodiments, a fan may be controlled to more than one speed and the
illumination source 205 may be controlled to produce illumination at more than one illumination setting. Steam, and other offending gases and odors can be extracted directly from the cooking area above the range top and areas immediate adjacent to the range top and passed through afilter 41 and ducting system at a rate adjustable by the user. For example, a user may press thefan switch indicator 223 a once, and thefan switch indicator 223 a may illuminate to a dim level (not shown). In some embodiments, when the user presses the fan switch again, afan switch indicator 223 b may illuminate to a bright level, as shown indisplay state 224. In some other embodiments for example, a user may press thelight switch indicator 225 a once, and thelight switch indicator 225 a may illuminate to a dim level (not shown). In some embodiments, when the user presses the light switch again, the light switch indicator 225 b may illuminate to a bright level, as shown in display state 226.

In some embodiments, theuser interface 11 shown inFIG. 3 a can be used in alternativerange hood systems 340 as shown inFIGS. 3 c and 3 d. - In some embodiments, the
user interface 11 can be mounted flush with ahousing 13 of therange hood system 300 and the switches or buttons and indicators (310, 312, 317 and 318) can be separate from theLCD 304. However some other embodiments can have alternative configurations. As described earlier, the range hood can comprise a plurality of different configurations. For example, as shown inFIG. 3 b, in some embodiments of the invention, therange hood 320 can comprise analternative user interface 11 with at least oneswitch assembly user interface 11 may be coupled with a transparent orsemi-transparent overlay fascia 31 mounted within a housing of therange hood system 320. In some embodiments, theoverlay fascia 31 may be colored, preferably to provide improved visual characteristics, including, but not limited to color, brightness, and contrast in well-lit or darkened rooms, aesthetic appearance, etc. In this embodiment, a dark coloredpolycarbonate overlay fascia 31 provides an improved contrast display to the user. In some embodiments, theuser interface 11 may emit a blue or blue-green light. In other embodiments, the display can emit a yellow, orange or substantially red light. It will be recognized that this particular embodiment need not be limited to the use of the colors described, and in fact any combination of user interface color can be used to provide the improveduser interface 11. As described earlier, it will also be recognized that the color emitted from theuser interface 11 can be changed by altering the light emission characteristics of the illumination source, or the light transmission characteristics of theoverlay fascia 31, or both. As shown inFIG. 3 b, in some embodiments, theuser interface 11 comprises a substantially rectangular display with rounded corners. In other embodiments, theuser interface 11 can be square, or at least partially circular. In some other embodiments, one or more visible light emitting components can be substantially integrated with the one or more buttons or switches. As discussed earlier, in some embodiments for example, as shownFIG. 3 b, therange hood systems 320 can comprise auser interface 11 that includes a plurality of buttons or switches that incorporate a visible light emitting device for communicating the status of at least one component of therange hood system 320. In some embodiments, at least a partial region of a button or switch inswitch assembly switch assembly range hood system 320. - In some embodiments, the
range hood system 320 can be configured and arranged to provide information on the operational characteristics of at least one component of therange hood system 320. As shown inFIG. 3 b, theLCD 321 can display the status of a fan within auser interface display 11, and in some embodiments can include a bar-graph type display. For example, in some embodiments as shown inFIG. 3 b, the activation status of a fan is provided on theuser interface 11, and in some embodiments can include a bar-graph type display 313, and afan icon 314. In some other embodiments as shown inFIG. 3 b, the activation status of theillumination source 305 is provided on theuser interface 11. For example, in some embodiments as shown inFIG. 3 b, the activation status of theillumination source 305 is presented to the user on theuser interface 11, and in some embodiments can include a bar-graph type display 315, and afan icon 316. In some further embodiments, other buttons and switches and indicators can be included in therange hood system 300. For example, theuser interface 11 of therange hood system 300 can include a fan delay-off button indicator 317, and a filterchange button indicator 318. - In some embodiments, when the fan (not shown), or other components such as an
illumination source 305 are not operational, theuser interface 11 will not be illuminated (shown as display state 322). After a user contacts one or more buttons or switches, theuser interface 11 can illuminate (shown as display state 330). In some embodiments, if the user takes no further action, (i.e. the user makes no further contact of one or more buttons or switches on the user interface display within 5 seconds), the display reverts to anoff display state 322. - In some embodiments, the speed of the fan can be varied in relation to the number of repeated contacts with the fan switch or button, for example as shown in
FIG. 3 b indisplay state 324. The speed status of the fan can be displayed within theLCD 321, and in some embodiments can include a bar-graph type display 313. The bar-graph display 313 as shown indisplay state 324 inFIG. 3 b for example shows two bars out of a total of three bars ‘filled’ or ‘darkened’ on a bar-graph indicative of the speed of a fan. In this embodiment, following an initial contact with theuser interface 11, theLCD 321 will illuminate as shown atdisplay state 330. Following a user contacting thefan switch indicator 323 b, a first bar of a fanspeed bar display 313 will become ‘filled’ or ‘darkened’ on a bar-graph indicative of the speed of the fan at the lowest speed setting, (not shown). Following a user contacting thefan switch indicator 323 b for a second time, the first bar of a fanspeed bar display 313 will remain ‘filled’ or ‘darkened’, and a second, adjacent bar will become ‘filled’ or ‘darkened’ indicative of the speed of the fan at a medium speed setting, (as shown inFIG. 3 b display state 324). Following a user contacting thefan switch indicator 323 b for a third time, the first and second bar of theLCD 321 wi11 remain ‘filled’ or ‘darkened’, and a third bar or adjacent bar of the fanspeed bar display 313 will become ‘filled’ or ‘darkened’ indicative of the speed of the fan at a high speed setting, (not shown). Skilled artisans will recognize the examples provided herein have many useful alternatives that fall within the scope of embodiments of the invention. For example, further fan speed settings can be accommodated by increasing the number of bars on the bar-chart, or by the use of alternative display formats intended to be representative of the magnitude of the speed of the fan. - In some embodiments, a fan delay-off feature can be used. For example, in some embodiments, if a fan is operating (at any speed setting), and the fan delay-
off button indicator 317 is pressed, the fan will operate for a further 10 minutes before the fan is automatically deactivated a control system (not shown). For example, as shown inFIG. 3 b, a delay-off interface can be presented to the user (shown in display state 332). In one embodiment, if the user has activated the delay-off feature by pressing the delay offbutton indicator 317, the delay-off indication icon and surrounding illuminated ring will blink on for 1 second and blink off for 1 second and repeat this cycle until the end of the 10 minute delay-off period (this is represented as 327 c in display state 332). In some embodiments, after the 10 minute delay off period has ended, the fan and any fan indicators shown on theuser interface 11 will turn off However the delay-off button indicator 317 will remain illuminated, and the delay-off feature will not deactivate theillumination source 305 if active. In some embodiments, if no other range-hood system 320 features are active, and the delay-off feature has passed the end of the 10 minute delay-off period, the control system will turn-off after an additional 5 minutes (i.e. theuser interface 11 will turn off as represented in display state 312). In some embodiments, the delay-off feature can be interrupted and halted at any time in the 10 minute delay-off period by pressing the delay-off button indicator 317 switch or button again. - Some embodiments can include an illumination status display within the
user interface 11. As shown inFIG. 3 b and theLCD 321, in some embodiments, the status of theillumination source 305 can be displayed within auser interface 11, for example the luminosity setting can be display on a bar-graph type display. In some embodiments, the luminosity of theillumination source 305 can be varied in relation to the number of repeated contacts with thelight switch indicator 312 switch or button. Furthermore, as shown inFIG. 3 b, the luminosity setting of theillumination source 305 can be displayed within auser interface 11, and in some embodiments can include a bar-graph type display, shown as the lightlevel bar display 315. Thedisplay state 326 inFIG. 3 b for example shows one bar out of a total of three bars ‘filled’ or ‘darkened’ on the lightlevel bar display 315 indicative of the intensity of theillumination source 305. In this embodiment, following an initial contact with theuser interface 11, the user interface will illuminate as shown indisplay state 330. Following a user contacting the light switch indicator 312 (shown as 325 a as in an initially unlit state in display state 322), a first bar of the lightlevel bar display 315 will become ‘filled’ or ‘darkened’ indicative of the luminosity of the illumination source is at a lowest setting. Following a user contacting the illumination switch indicator 312 (shown as 325 b as in an initially lit state in display state 330), for a second time, the first bar of the lightlevel bar display 315 will remain ‘filled’ or ‘darkened’, and a second, adjacent bar will become ‘filled’ or ‘darkened’ indicating the luminosity of the illumination source is at a medium speed setting, (not shown). Following a user contacting theswitch indicator 312 for a third time, the first and second bar of the lightlevel bar display 315 will remain ‘filled’ or ‘darkened’, and a third or adjacent bar will become ‘filled’ or ‘darkened’ indicative of the luminosity of the illumination source is at a high setting, (not shown). Skilled artisans will recognize the examples provided herein have many useful alternatives that fall within the scope of embodiments of the invention. For example,further illumination source 305 luminosity settings can be accommodated by increasing the number of bars on the bar-graph, or by the use of alternative display formats intended to be representative of the luminosity of theillumination source 305. - Some embodiments of the invention can comprise an
alternative user interface 11 that can be used to control other features of a range hood. For example, referring now toFIGS. 4 a and 4 b showingrange hood systems clock 401 comprising a 4-digit numeral display, and atimer switch indicator 460. Furthermore, in some other embodiments, other fan delay-off features can be implemented. In some further embodiments, if theuser interface 11 in the area of theclock 401 is pressed and held for three seconds, a clock setting mode is activated, and the clock numerals will blink. In the clock setting mode, the lightswitch indicator button 312 is used to index the minutes, and the fanswitch indicator button 310 is used to index the hours. Each press of thebutton 310 will index the time by 1 hour. In some other embodiments, if thebutton 310 is pressed and held, the hour setting will index 1 hour for every half second that the button is held. Each press of thebutton 312 will index the time by 1 minute. If thebutton 312 is pressed and held, the minutes will index at 1 minute every half second, after 3 seconds of holding, the setting will index 5 minutes every half second held. In some embodiments, if the user again presses theuser interface 11 in the area of theclock 401, the time will be set, the numerals will stop blinking, and the clock setting will be exited. The user can leave thebuttons - Some other embodiments of the invention include additional features. For example, if the fan is on (any speed setting), and the fan delay-
off button indicator 317 is pressed, the delay off feature of a control system (not shown) will be activated. Theclock 401 display will indicate thedelay time 455, with a default time of five minutes, with the first two digits displaying “DL” to indicate the function is in the delay-off mode (e.g. shown as DL:10 indisplay state 412 inFIG. 4 a, and DL:05 as shown inFIG. 4 b, in display state 435). In some embodiments, the user can continue to press the fan delay-off button indicator 317 until the desired delay-off time is indicated in thedelay time 455 display. In some embodiments, each button press increments the delay-off time by five minutes, with a maximum of 30 minutes. In some embodiments, after 30 minutes, the setting will start again at 5 minutes. In some embodiments, when the desired setting is reached, and the user does not press the fan delay-off button indicator 317 again, the current setting is fixed, but will disappear from thedisplay area 455. The delay timer will then operate, but not be shown in the display area. In some further embodiments, when the delay-off feature is activated (by pressing the fan delay-off button indicator 317), theuser interface 11 can display a representation of a analog style ‘minute hand’ on the delay off ‘clock icon’ represented on the fan delay-off button indicator 317. The ‘minute hand’ will animate (rotate) during the delay off count-down period. In some embodiments, after the set time has elapsed, the fan will turn off, and the fan and the minute hand will stop rotating. In some embodiments, the delay-off feature will not turn off theillumination source 305 or any feature other than the fan. Furthermore, in some embodiments, the delay-off feature can be turned off at any time during operation by pressing the fan delay-off button indicator 317 again when activated. The fan will remain on the current setting, and the delay-off clock icon on the fan delay-off button indicator 317 will stop rotating. If no other features are active, and the delay-off feature turns off the fan, the control system (not shown) will turn off after an additional 5-seconds and the clock will stay on. - Referring again to
FIGS. 4 a and 4 b, some embodiments of the invention can include a clock. For example when the control system has deactivated the user interface, a clock can be displayed on the screen with no backlighting (display 402). Some embodiments can include a clock as a standard 12 hour clock with no am/pm indicator. If the clock area is pressed, the clock illumination will be turned on (as shown in the display 410). If the clock area is pressed again, it will again be turned off. The default is clock “on”. However, if the clock is turned off, the delay off and timer settings will still be illuminated in the clock area when activated. After the delay off or timer functions are deactivated, the clock will turn back off. In some embodiments, the delay-off feature will temporarily override the clock when the delay off time is being set, and the clock will return once the delay off time is selected. The timer will temporarily override the clock when the timer is active. The clock will return once the timer is deactivated. - In some additional embodiments of the invention, the
range hood system timer switch indicator 460. In some embodiments, thetimer switch indicator 460 can include an ‘hour-glass’ icon or image that can be animated. For example, referring toFIG. 4 a (the display state 416) andFIG. 4 b (the display 438), if thetimer switch indicator 460 is pressed, a timer feature will be activated. The numbers in theclock 401 will indicate the timer setting in minutes, with a default of zero minutes, and the digits will blink. In some embodiments, when the timer feature is activated, the user can index the timer upwards utilizing thelight switch indicator 312 button, and index the timer down using thefan switch indicator 310 button. Eachtime button buttons clock 401 will stop blinking, but the countdown will continue to show in theclock 401 until it is deactivated. The timer will show and countdown minutes and seconds. - In some further embodiments of the invention, when the timer feature described about is activated, an ‘hour-glass’ icon or image that can be animated on the timer switch indicator 460 (shown
display state 416 inFIG. 4 a, anddisplay state 438 inFIG. 4 b). In some embodiments, the ‘hour-glass’ will animate, and the ‘sand’ in the top of the hour glass will empty and fill in the bottom. In some embodiments, when all of the sand is in the bottom, the hourglass will flip and the sequence will start again. In some embodiments, after the set time has elapsed, an audible beep will be enunciated at one beep every two seconds. The ‘hour-glass’ animation will stop, and theclock 401 will show and flash “00:00”. In some embodiments, when the user presses thetimer switch indicator 460 again, the clock will return, and the audible beep sequence will stop. The timer feature can be turned off at any time during operation by pressing thetimer switch indicator 460 again when activated. Theclock 401 will return to displaying the time, and the ‘hour-glass’ animation will stop. In some embodiments, if no other features are active, and the timer feature is ended, the control will turn off the set time displayed on theclock 401 after an additional five seconds. - As shown and described above and in
FIGS. 1 , 2 a-2 e, 3 a-3 f, and 4 a-4 b, some embodiments of the invention can be installed adjacent to a cooking area (e.g., in a kitchen). For example, in some embodiments, the range hood systems as described can be installed immediately adjacent to, or above a cook top or range top. During operation, especially when the range top features multiple cooking surfaces, or during multiple sequential or prolonged cooking episodes, the range hood may be exposed to high temperatures. The range hood outer surface and internal components may be heated by convection, IR-heat, and from steam, hot gases and cooking effluent, or may be operated in an environment with a high ambient temperature. In some embodiments of the invention, a heat monitoring system (not shown) can be included. For example, referring again toFIG. 4 a (the display state 414) andFIG. 4 b (the display state 437), one or more embodiments may feature a heat sentry mode (shown as an illuminated icon 415). In some embodiments, when a heat sensor (not shown) detects a high level of heat , (e.g. approx. 70° C. at the control board, or at a temperature recommended by the supplier), the heat sentry control system (not shown) will automatically turn the fan to its highest setting. Theheat sentry mode 415 icon will illuminate, and a fan icon displayed on thefan switch indicator 310 will animate (rotate) at its highest speed. Theheat sentry mode 415 will remain activated until temperatures are reduced by more than 10° C. at the control board (not shown). In some embodiments, when theheat sentry mode 415 is activated, the user cannot adjust the fan speed setting, and if the delay-off feature is activated, it will be temporarily interrupted until theheat sentry mode 415 is deactivated. After theheat sentry mode 415 is deactivated, the fan functions will return to the state they were prior to heat sentry activation, and theheat sentry mode 415 icon will disappear. - In some embodiments, when the fan (not shown), or other components such as an
illumination source 305 are not operational, theuser interface 11 will not be illuminated (shown asdisplay state 402 inFIG. 4 a anddisplay state 422 inFIG. 4 b). In some embodiments, theclock 401 will be visible to a user (as shown). After a user contacts one or more buttons or switches the user interface display can illuminate (shown asdisplay state 410 inFIG. 4 a anddisplay state 430 inFIG. 4 b). In some embodiments, if the user takes no further action, (i.e. the user makes no further contact of one or more buttons or switches on the user interface display within 5 seconds), the display reverts to an off display state (shown asdisplay state 402 inFIG. 4 a anddisplay state 422 inFIG. 4 b). In some other embodiments, when the fan is in use, thefan switch indicator 310 will show an illuminated animated fan icon (represented indisplay state 404 inFIG. 4 a anddisplay state 424 inFIG. 4 b). In some other embodiments, when theillumination source 305 is active, the light switch indicator can display an illuminated icon, (e.g. shown as a filled light bulb indisplay state 406 inFIG. 4 a anddisplay state 426 inFIG. 4 b). - In some embodiments of the invention, when any switch or button on the
user interface 11 is contacted or pressed, a control system (not shown) will send a control signal to an audio system (now shown). In some embodiments, the audio system will create an audible sound when any switch or button on theuser interface 11 is contacted or pressed. In some embodiments, the sound is the same, or substantially similar to a “click”. In some other embodiments, the sound is the same, or substantially similar to the sound emitted by other common hand-held devices (such as a cellular phone, a smart phone, a tablet or a PDA). - It will be appreciated by those skilled in the art that while the invention has been described above in connection with particular embodiments and examples, the invention is not necessarily so limited, and that numerous other embodiments, examples, uses, modifications and departures from the embodiments, examples and uses are intended to be encompassed by the invention.
