Abstract

An interactive appliance is provided. The interactive appliance includes at least a housing, and an intelligent control disposed within the housing. One or more lighting devices are electrically connected to the intelligent control, as are one or more sensors. The sensors provide sensor data for the interactive appliance. The intelligent control is configured to alter operation of at least one of the one or more lighting devices based on data provided by the sensor to provide interactive feedback to a user of the interactive appliance. The feedback can include altering light intensity, color, consistency, or the like depending on the sensor data. Furthermore, the lighting device can be placed on a surface, such as an exterior surface of the housing of the appliance, or can be disposed within an interior portion of the appliance.

Claims

1. An interactive appliance comprising:

an appliance housing having an exterior;

a door having a handle;

a plurality of lighting devices electrically and interactively connected to a plurality of proximity sensors that each acquire sensor data within a separate sensor field that extends a distance away from the exterior of the appliance housing; and

wherein each of the plurality of lighting devices perform a programmed function and are responsive to a disruption of one or more of the sensor fields; and

wherein a disruption in at least one of the sensor fields activates at least one of the plurality of lighting devices proximate the bottom of the refrigerator and the lighting device proximate the bottom of the refrigerator illuminates a general boundary area proximate the bottom of the refrigerator;

wherein the plurality of lighting devices are integrated into a user facing surface of the exterior of the interactive appliance; and

wherein at least one of the plurality of lighting devices is positioned on a surface of the handle facing the appliance.

2. The interactive appliance of claim 1, further comprising a plurality of door proximity sensors positioned on an exterior surface of the door, each proximity sensor having an associated exterior sensor field loop that extends outward and back toward the proximity sensor, wherein disruption of one of the exterior sensor fields activates at least one exterior appliance lighting device that illuminates an area proximate the appliance.

3. The interactive appliance of claim 2, further comprising a plurality of interior proximity sensors wherein each of the plurality of interior proximity sensors senses motion within an interior volume of the refrigerator and a plurality of interior lighting devices wherein an interior lighting device is associated with each defined subvolume with the interior of the appliance such that movement sensed by one of the interior proximity sensors alters the lighting intensity of the defined subvolume.

4. The interactive appliance of claim 1, further comprising a plurality of interior proximity sensors wherein each of the plurality of interior proximity sensors senses motion within an interior volume of the refrigerator and a plurality of interior lighting devices wherein an interior lighting device is associated with each defined subvolume with the interior of the appliance such that movement sensed by one of the interior proximity sensors alters the lighting intensity of the defined subvolume.

5. The interactive appliance of claim 1, wherein the plurality of lighting devices are on the exterior of the appliance and an interior of the appliance and at least one lighting device is on an exterior surface of a handle.

6. The interactive appliance of claim 1, wherein the plurality of lighting devices include a plurality of interior lighting devices that illuminate an interior of appliance and a plurality of exterior lighting devices.

7. The interactive appliance of claim 6, wherein the plurality of lighting devices further include at least one dispenser illuminating lighting device that, when activated, illuminates a dispenser on the exterior of the appliance and at least one of the plurality of proximity sensors are associated with the dispenser to determine if a container is proximate the dispenser.

8. The interactive appliance of claim 6, wherein the plurality of interior lighting devices have an alterable intensity and the interactive appliance further comprises at least one time sensor and a dimmer switch and the alterable intensity is changed based upon input from either the at least one time sensor or the dimmer switch.

9. The interactive appliance of claim 1, wherein the illumination of at least one of the plurality of lighting devices is an altered light color based upon disruption of at least one of the sensor fields.

10. The interactive appliance of claim 1, wherein the light intensity and visible light color of the plurality of lighting devices is altered based upon input from at least one of the proximity sensors over time.

11. The interactive appliance of claim 8, wherein the alterable intensity is changed based upon both the input from the at least one time sensors and the input from the dimmer switch.

12. The interactive appliance of claim 1, wherein the operation of the plurality of lighting devices comprises a predicted usage of the interactive appliance based on the sensor data to provide feedback to the user based upon the predicted usage.

13. An interactive refrigerator, comprising:

a refrigerator cabinet having an exterior surface and a dispenser on the exterior surface that dispenses water and ice;

a door for providing access to a compartment within the refrigerator cabinet;

at least one dispenser lighting device associated with the dispenser and operably connected to a plurality of dispenser proximity sensors associated with and positioned on a dispenser well wall of the dispenser where the dispenser proximity sensors have a loop sensor field associated therewith that extends away from and through a recessed dispensing area of the dispenser and wherein the at least one dispenser lighting device illuminates the recessed dispensing area of the dispenser upon a disruption in the sensor field;

a plurality of door proximity sensors positioned on the exterior surface of the door, each proximity sensor having an associated exterior sensor field loop that extends outward and back toward the proximity sensor, wherein disruption of one of the exterior sensor fields activates at least one exterior appliance lighting device that illuminates an area proximate the appliance; and

a plurality of interior proximity sensors wherein each of the plurality of interior proximity sensors senses motion within an interior volume of the refrigerator and a plurality of interior lighting devices wherein an interior lighting device is associated with each defined subvolume with the interior of the appliance such that movement sensed by one of the interior proximity sensors alters the lighting intensity of the defined subvolume.

14. The interactive refrigerator of claim 13 further comprising a handle lighting device and a door opened time sensor that senses the amount of time a door having a handle associated with the handle lighting device has been open where, after a period of time has passed the time sensor causes the handle lighting device to illuminate the handle.

15. The interactive refrigerator of claim 14, wherein the interactive refrigerator further comprises an environmental sensor configured to sense ambient light in a room where the appliance is located.

16. The interactive refrigerator of claim 15, wherein the environmental sensor, the proximity sensors and the time sensor are positioned on a surface chosen from the group consisting of a liner surface, a shelf surface, a door surface, an interior crisper surface, a refrigerator cabinet surface, a dispenser well surface, a handle surface, and a dispenser mount fascia surface.

17. The interactive refrigerator of claim 15, wherein the lighting intensity or visible light color of the dispenser lighting device associated with the dispenser is altered based upon feedback from the dispenser proximity sensors and the environmental sensor.

18. The interactive refrigerator of claim 13, wherein the proximity sensors include both capacitive sense sensors and infrared light sensors.

19. The interactive refrigerator of claim 13, wherein the predefined subvolume is a drawer within the interior of the appliance where the lighting intensity of the light illuminating the drawer provided by the lighting device associated with the drawer is altered upon sensing of motion by the interior proximity sensor associated with the drawer and wherein the interactive appliance further comprises a time sensor which after a predetermined amount of time has passed, causes the lighting device associated with the door to flicker or pulse on and off thereby allowing a user that the drawer was left open.
