A refrigerator having a dispenser that includes an outlet and that is configured to dispense content through the outlet and along an output flow path. The refrigerator also includes a detection unit configured to detect user activity that is indicative of a desire to fill a container with content using the dispenser. The refrigerator further includes an optical system that is configured to, in response to detecting the user activity, direct a beam of light along at least a portion of the output flow path of the dispenser to assist a user in positioning a container to receive content dispensed along the output flow path.

1. A refrigerator comprising: a compartment;a door configured to open and close the compartment;a dispenser that includes an outlet and that is configured to dispense content through the outlet and along an output flow path, the dispenser including a dispensing cavity that is configured to accommodate a container being filled by the dispenser and that is defined in the door of the refrigerator;a display;a detection unit configured to detect a container in the dispensing cavity; anda controller configured to: assess output from the detection unit to determine whether the container is in the dispensing cavity;based on the assessment of the output from the detection unit, detect that the container is not present in the dispensing cavity;based on the detection that the container is not present within the dispensing cavity: disable the dispenser from dispensing content because no container is present to receive content, andcontrol the display to display a status message that indicates that a user needs to place the container under the outlet to enable operation of the dispenser;after display of the status message that indicates that the user needs to place the container under the outlet to enable operation of the dispenser, detect the container in the dispensing cavity based on output from the detection unit;based on the detection of the container in the dispensing cavity, enable the dispenser to dispense content and control the dispenser to dispense, into the container, a volume of content that is automatically, without user intervention, set using output from the detection unit that relates to a size of the container detected in the dispensing cavity; andbased on completion of dispensing, control the display to display a status message that indicates that the container was successfully filled to the automatically set volume of content. 2. The refrigerator of claim 1, wherein the detection unit comprises at least two sensors positioned on a top surface of the dispensing cavity that defines a top of the dispensing cavity and at least two sensors positioned on a back surface of the dispensing cavity that defines a back of the dispensing cavity. 3. The refrigerator of claim 1, wherein the controller is configured to monitor the container as the container is being filled by the dispenser and control the dispenser based on the monitoring. 4. The refrigerator of claim 3: wherein the controller is configured to monitor the container as the container is being filled by the dispenser by detecting the container being removed from the dispensing cavity as the dispenser is filling content into the container; andwherein the controller is configured to control the dispenser based on the monitoring by stopping dispensing content based on the detection of the container being removed from the dispensing cavity as the dispenser is filling content into the container. 5. The refrigerator of claim 1, wherein the detection unit comprises at least two sensors positioned on an outlet housing that houses the outlet of the dispenser. 6. The refrigerator of claim 2, wherein the at least two sensors positioned on the top surface of the dispensing cavity that defines the top of the dispensing cavity are positioned on an outlet housing that houses the outlet of the dispenser. 7. The refrigerator of claim 6, wherein the at least two sensors positioned on the top surface of the dispensing cavity are position detectors that are configured to detect presence of the container within the dispensing cavity and detect a distance between the container and the corresponding sensor. 8. The refrigerator of claim 6, wherein the at least two sensors positioned on the back surface of the dispensing cavity are position detectors that are configured to detect presence of the container within the dispensing cavity and detect a distance between the container and the corresponding sensor. 9. The refrigerator of claim 6, wherein the at least two sensors positioned on the top surface of the dispensing cavity and the at least two sensors positioned on the back surface of the dispensing cavity are position detectors that are configured to detect presence of the container within the dispensing cavity and detect a distance between the container and the corresponding sensor. 10. The refrigerator of claim 1, wherein the controller is configured to control the dispenser to dispense, into the container, the volume of content that is automatically, without user intervention, set using output from the detection unit that relates to a size of the container detected in the dispensing cavity by: determining volume characteristics of the container based on sensor data sensed by the detection unit;identifying a volume of content that the container is capable of receiving based on the determined volume characteristics;automatically, without user intervention, setting the identified volume of content that the container is capable of receiving; andcontrolling the dispenser to dispense the identified volume of content that was automatically set. 11. The refrigerator of claim 10, wherein the controller is configured to determine volume characteristics of the container based on sensor data sensed by the detection unit by estimating volume characteristics of the container based on data from the detection unit. 12. The refrigerator of claim 10, wherein the controller is configured to determine volume characteristics of the container based on sensor data sensed by the detection unit by estimating measurements of the container detected in the dispensing cavity and applying the estimated measurements to a volume calculation formula to estimate the volume of the container. 13. The refrigerator of claim 1, wherein the detection unit comprises at least four sensors positioned at one or more surfaces of the dispensing cavity. 14. The refrigerator of claim 13, wherein the at least four sensors are position detectors that are configured to detect presence of the container within the dispensing cavity and detect a distance between the container and the corresponding sensor. 15. The refrigerator of claim 13, wherein the at least four sensors comprise at least two sensors on an outlet housing that houses the outlet of the dispenser. 16. The refrigerator of claim 1, wherein the detection unit comprises at least two sensors positioned at one or more surfaces of the dispensing cavity. 17. The refrigerator of claim 16, wherein the at least two sensors are position detectors that are configured to detect presence of the container within the dispensing cavity and detect a distance between the container and the corresponding sensor. 18. The refrigerator of claim 16, wherein the at least two sensors are positioned on an outlet housing that houses the outlet of the dispenser. 19. The refrigerator of claim 18, wherein the at least two sensors are position detectors that are configured to detect presence of the container within the dispensing cavity and detect a distance between the container and the corresponding sensor. 20. The refrigerator of claim 1, wherein the controller is configured to display a numeric representation of the automatically set volume of content with a unit of measurement.
