A sensing system for a refrigerator dispensing system is used to sense the presence, positioning, height and shape of a container placed in a dispensing well. When the presence of the container is sensed in the dispensing well and the container is properly positioned relative to a dispensing nozzle
A sensing system for a refrigerator dispensing system is used to sense the presence, positioning, height and shape of a container placed in a dispensing well. When the presence of the container is sensed in the dispensing well and the container is properly positioned relative to a dispensing nozzle of the well, a dispensing operation can be performed. The actual dispensing operation is regulated based on the height and shape of the container. In this manner, dispensing operations can only be performed when a container is appropriately arranged in the dispensing well and the dispensing operation will be timely terminated based the size and shape of particular container employed.

What is claimed is: 1. A refrigerator comprising: a cabinet; at least one refrigerated compartment arranged within the cabinet; a door mounted to the cabinet for selectively providing access to the at least one refrigerated compartment; and a dispenser assembly provided in the door for selectively releasing at least one of water and ice to a consumer, said dispenser assembly including: a main housing; a dispenser well provided in the main housing, said dispenser well including an upper portion, a base section for supporting a container, a recessed upstanding wall section and opposing side wall sections; a dispensing outlet arranged in the upper portion of the dispenser well for delivering a container filling towards the base section; and a sensor system including at least one sensor exposed to the dispenser well, said at least one sensor being configured to detect each of a presence, positioning, height and shape of a container placed in the dispensing well. 2. The refrigerator according to claim 1, wherein the at least one sensor is constituted by a plurality of infrared sensors mounted along the opposing side wall sections of the dispensing well. 3. The refrigerator according to claim 2, wherein the plurality of infrared sensors constitutes an array of spaced, paired infrared sensors mounted along the opposing side wail sections. 4. The refrigerator according to claim 1, wherein the at least one sensor constitutes a retro-reflective infrared sensor. 5. The refrigerator according to claim 4, wherein the at least one sensor constitutes multiple retro-reflective sensors mounted, in a vertically offset configuration, along opposite wall sections of the dispensing well. 6. The refrigerator according to claim 1, wherein the at least one sensor is constituted by a plurality of ultrasonic sensors exposed to the dispensing well. 7. The refrigerator according to claim 6, wherein the plurality of ultrasonic sensors are mounted along the upper portion of the dispensing well. 8. The refrigerator according to claim 1, wherein the at least one sensor is constituted by at least one photoelectric sensor exposed to the dispensing well. 9. The refrigerator according to claim 8, wherein the at least one photoelectric sensor is rotatable by a motor relative to the main housing for scanning the dispensing well. 10. The refrigerator according to claim 9, wherein the at least one photoelectric sensor is rotatable by a motor about a substantially horizontal axis. 11. The refrigerator according to claim 9, wherein the at least one photoelectric sensor is vertically shiftable relative to the main housing for scanning the dispensing well. 12. The refrigerator according to claim 8, wherein the at least one photoelectric sensor is employed to determine a material composition of the container. 13. The refrigerator according to claim 1, wherein the at least one sensor is constituted by a digital image captive device exposed to the dispensing well, wherein the digital image captive device is a digital camera. 14. The refrigerator according to claim 13, wherein the digital image captive device includes a light source for illuminating the container for imaging purposes. 15. The refrigerator according to claim 13, wherein the digital image capture device is also employed to determine a material of the container. 16. A method of dispensing a liquid from a refrigerator door mounted dispenser assembly including a dispensing well having a water-based dispensing outlet comprising: sensing each of a presence, position, height and shape of a container placed in the dispensing well; initiating a dispensing operation by introducing a water-based material into the container when the presence of the container is sensed in the dispenser well and the container is properly positioned relative to the nozzle; and regulating the dispensing operation based on the height and shape of the container. 17. The method of claim 16, wherein each of the presence, position, height and shape of the container is determined based on signals received from a plurality of infrared sensors constituted by a first array of vertically spaced infrared sensors mounted along one side wall section of the dispensing well and a second array of vertically spaced infrared sensors mounted along an opposing side wall section of the dispensing well, with the first and second arrays of vertically spaced infrared sensors being vertically offset relative to each other. 18. The method of claim 16, wherein each of the presence, position, height and shape of the container is determined based on signals received from a plurality of ultrasonic sensors mounted along an upper portion of and exposed to the dispensing well. 19. The method of claim 16, wherein each of the presence, position, height and shape of the container is determined based on signals received from at least one photoelectric sensor exposed to the dispensing well. 20. The method of claim 19, further comprising: rotating the at least one photoelectric sensor, through the use of a motor, to scan the dispensing well. 21. The method of claim 20, further comprising: vertically shifting the at least one photoelectric sensor to scan the dispensing well. 22. The method of claim 21, further comprising: using the at least one photoelectric sensor to determine a material composition of the container. 23. The method of claim 16, wherein each of the presence, position, height and shape of the container is determined based on signals received from a digital image captive device exposed to the dispensing well, wherein the digital image captive device is a digital camera. 24. The method of claim 23, further comprising: operating a light source of the digital image captive device to illuminate the container for imaging purposes.
