Abstract

A refrigerator which is capable of being connected to the Internet and performing a variety of multimedia functions, and a method for controlling the same. A multimedia controller which controls the multimedia functions of the refrigerator is driven under the control of a refrigerator controller which controls refrigerating and freezing environments of the refrigerator. Even when an accident, such as a power failure or etc., occurs, the multimedia controller is given time in which it can be normally or closed down or ended. Therefore, a warning window is not displayed on a display unit of the refrigerator upon the driving of the multimedia controller, thus reassuring a user that the refrigerator has not failed.

Claims

1. A refrigerator for performing multimedia functions, comprising:

a power supply that supplies power to said refrigerator;

a refrigerator controller that receives said power from said power supply to control refrigerating and freezing environments of said refrigerator;

a multimedia controller that receives said power from said power supply via said refrigerator controller to control the multimedia functions of said refrigerator; and

an interface that converts signals exchanged between said multimedia controller and said refrigerator controller into signals respectively complying with one of a standard of said multimedia controller and a standard of said refrigerator controller.

2. The refrigerator as set forth in claim 1, further comprising a reset switch that turns ON/OFF supply of said power from said power supply to said refrigerator controller and multimedia controller to reset said refrigerator controller and said multimedia controller.

3. The refrigerator as set forth in claim 2, wherein said refrigerator controller comprises a microcomputer that controls the refrigerating and freezes environments of said refrigerator, and generates a drive signal in response to a reset signal input from said reset switch to control ON/OFF states of said multimedia controller.

4. The refrigerator as set forth in claim 3, wherein said refrigerator controller further comprises a timer that counts time elapsed from the input of said reset signal from said reset switch to said microcomputer, said microcomputer generating said drive signal if the elapsed time counted by said timer is greater than a predetermined reference time period.

5. The refrigerator as set forth in claim 3, wherein said refrigerator controller further comprises a signal sender that sends said drive signal generated by said microcomputer to said multimedia controller.

6. The refrigerator as set forth in claim 3, wherein said refrigerator controller further comprises switching device that selectively supplies said power from said power supply to said refrigerator controller and said multimedia controller.

7. The refrigerator as set forth in claim 6, wherein said switching device comprises:

a power charger that is charged with said power from said power supply to a predetermined level; and

a power switch that selectively supplies the charged power from said power charger to said refrigerator controller and said multimedia controller.

8. The refrigerator as set forth in claim 5, wherein said multimedia controller comprises a multimedia microcomputer that controls the multimedia functions of said refrigerator, said multimedia microcomputer being turned on in response to said drive signal.

9. A method for controlling a refrigerator performing multimedia functions, said method comprising:

inputting a reset signal to a refrigerator controller to reset said refrigerator, said refrigerator controller controlling refrigerating and freezing environments of said refrigerator;

sending a drive signal from said refrigerator controller to a multimedia controller, said multimedia controller controlling the multimedia functions of said refrigerator; and

driving said multimedia controller in response to said drive sent signal sent.

10. The method as set forth in claim 9, wherein inputting comprises allowing input of said reset signal through a reset switch, said reset switch being operated to reset said refrigerator.

11. The method as set forth in claim 9, further comprising setting a reference period of time in said refrigerator controller before said sending is performed, said sending comprising further sending said drive signal from said refrigerator controller to said multimedia controller after said reference time period, from the input of said reset signal, elapses.

12. The method as set forth in claim 11, wherein said further sending comprises:

allowing said refrigerator controller to count time elapsed from the input of said reset signal;

further allowing said refrigerator controller to compare the counted elapsed time with said reference time period; and

additionally allowing said refrigerator controller to generate said drive signal if the counted elapsed time is greater than said reference time period.

13. The method as set forth in claim 11, wherein said reference time period is modifiable.
