Abstract

A refrigerator includes a dispenser having a dispenser well, a control for regulating a product dispensing operation, and an optical sensing system includes a camera within the dispenser well in communication with a controller for controlling the filling of a container within the dispenser well based on image data. The image data can used to detect at least one of a presence of a container in the dispenser well, a height of liquid within the container, a height of ice within the container and a shape of the container within the dispenser well, as well as to adjust a dispensing rate of product.

First claim

What is claimed is:

1. A refrigerator comprising:
a dispenser assembly for selectively releasing at least one of a liquid and ice into a container during a dispensing operation, said dispenser assembly including:
a controller for regulating the dispensing operation of the dispenser assembly; and
a camera adapted to send image data to the controller, wherein the controller regulates the dispensing operation based on the image data, and the controller varies a rate at which a product is dispensed multiple times throughout the dispensing operation.

2. The refrigerator according to claim 1 , further comprising: a dispenser well, wherein the camera is exposed to the dispenser well.

3. The refrigerator according to claim 2 , further comprising:
at least one refrigerated compartment; and
a door mounted for selectively providing access to the at least one refrigerated compartment, said dispenser well being provided, at least partially, in the door.

4. The refrigerator according to claim 3 , wherein the at least one refrigerated compartment constitutes a freezer compartment.

5. The refrigerator according to claim 4 , wherein the door constitutes a freezer door.

6. The refrigerator according to claim 2 , wherein the camera is located within the dispenser well.

7. A refrigerator comprising:
a dispenser assembly for selectively releasing at least one of a liquid and ice into a container during a dispensing operation, said dispenser assembly including:
a dispenser well
a controller for regulating the dispensing operation of the dispenser assembly; and
a camera located within and exposed to the dispenser well, the camera being adapted to send image data to the controller, wherein the controller regulates the dispensing operation based on the image data, wherein the camera is positioned for imaging a height of ice within a container in the dispenser well or the camera is positioned for imaging a shape of a container within the dispenser well.

8. The refrigerator according to claim 1 , wherein the controller performs video processing of the image data.

9. A dispenser assembly for selectively releasing at least one of a liquid and ice into a container during a dispensing operation, said dispenser assembly including:
a controller for regulating the dispensing operation of the dispenser assembly; and
a camera adapted to send image data to the controller, wherein the controller regulates the dispensing operation based on the image data, and the controller varies a rate at which a product is dispensed multiple times throughout the dispensing operation.

10. The dispenser assembly according to claim 9 , further comprising: a dispenser well, wherein the camera is exposed to the dispenser well.

11. The dispenser assembly according to claim 10 , wherein the dispenser well is provided in a door of a refrigerator.

12. The dispenser assembly according to claim 11 , wherein the camera is located within the dispenser well.

13. The dispenser assembly according to claim 10 , wherein the camera is positioned for imaging at least one of a height of ice within a container in the dispenser well and a shape of the container within the dispenser well.

14. The dispenser assembly according to claim 9 , wherein the controller performs video processing of the image data.

15. A method of dispensing a product from a refrigerator dispenser assembly including a dispenser well, the method comprising:
transmitting image data from a camera mounted in the dispenser well to a controller;
regulating dispensing of the product by the controller based on the image data;
varying a rate at which the product is dispensed during a dispensing event; and
varying the rate multiple times throughout the dispensing event.

16. The method of claim 15 , wherein the product is constituted by at least one of water and ice.

17. The method of claim 15 , further comprising: regulating the dispensing of the product based on video image data.

18. The method of claim 15 , wherein the image data is directed to at least one of a height of ice within a container in the dispenser well and a shape of the container within the dispenser well.

19. A refrigerator comprising:
a dispenser assembly for selectively releasing at least one of a liquid and ice into a container during a dispensing operation, said dispenser assembly including:
a controller for regulating the dispensing operation of the dispenser assembly; and a camera adapted to send image data to the controller, wherein the controller regulates the dispensing operation based on the image data, wherein the controller performs video processing of the image data and performing video processing of the image data includes performing video processing of real-time video image data.

20. The dispenser assembly according to claim 14 , wherein performing video processing of the image data includes performing video processing of real-time video image data.
