Abstract

A home refrigerator system (200) includes an enclosure (202) that defines an interior (203) for storing food (223, 224), a machine (209) for cooling the interior (203), a door (205) usable for accessing the interior (203), and a camera (252) for imaging the interior (203) while the door (205) is shut. The camera generates a signal (284) encoding the image of the interior. The signal (284) can be viewed on a screen (286) outside the interior, to assist in decision-making without opening the door (205).

31. The system of claim 30, in which

the screen is further adapted to display television images, and

the imaging switch is further adapted to control which one of the imaged interior and television images is displayed by the screen.

32. The system of claim 30, in which

the imaging switch is adapted to be actuated by a pushbutton.

33. The system of claim 30, in which

the imaging switch is adapted to be actuated by an electrical signal.

34. The system of claim 30, in which

when the imaging switch is actuated, it activates the one of the screen and the camera, and

when the actuation is discontinued, activating is continued for a period of time.

35. The system of claim 1, further comprising:

a second camera coupled with the enclosure and positioned to image at least a portion of the interior when the door is shut.

36. The system of claim 35, in which
