Abstract

A domestic appliance, shown in the form of a refrigerator, includes a cabinet within which is defined at least one compartment. A controller is mounted to the appliance for controlling various operating parameters of the appliance. The controller also includes a memory having stored therein a plurality of operating parameters associated with a plurality of appliance models. The appliance has an identification element affixed thereto and a communication device that is operatively connected to the controller. The communication device receives signals that provide programming instructions to the controller to activate particular ones of the plurality of operating parameters associated with the respective appliance model. In this manner, a universal controller can be employed in any one of a wide range of appliance models.

Claims

1. A domestic appliance comprising:

a cabinet;

a door pivotally mounted relative to the cabinet;

a universal controller for regulating operation of the domestic appliance;

a non-volatile memory associated with the controller, said non-volatile memory having stored therein a plurality of operating parameters associated with a plurality of models of the appliance;

means for identifying a particular model of the appliance, with said particular model having associated therewith only particular ones of the plurality of operating parameters; and

means for communicating with the controller to activate the particular ones of the operating parameters associated with the particular model of the appliance.

2. The domestic appliance according to claim 1, wherein the identifying means constitutes a bar code.

3. The domestic appliance according to claim 2, wherein the bar code is affixed to the cabinet.

4. The domestic appliance according to claim 1, wherein the communicating means constitutes a wireless communication port operatively coupled to the controller, said wireless communication port being adapted to receive programming data that activates the particular ones of the operating parameters associated with the particular domestic appliance.

5. The domestic appliance according to claim 4, wherein the communicating means constitutes a wireless receiver arranged in the domestic appliance, said wireless receiver being operatively connected to the controller.

6. The domestic appliance according to claim 1, further comprising:

a user interface having a plurality of control elements for inputting operating parameters of the domestic appliance, said communicating means being constituted by manual inputs to the controller through the control elements on the user interface.

7. The domestic appliance according to claim 1, wherein the plurality of operating parameters include compartment temperature control points, minimum and maximum set points, thermal performance data and product feature programming.

8. The domestic appliance according to claim 7, wherein the plurality of operating parameters include instructions for controlling a plurality of domestic appliance accessories.

9. The domestic appliance according to claim 8, wherein the domestic appliance constitutes a refrigerator.

10. The domestic appliance according to claim 9, wherein the plurality of domestic appliance accessories includes dispenser controls and temperature controlled storage bins.

11. A method of programming a universal domestic appliance controller comprising:

reading an indicator attached to a domestic appliance, said indicator designating a particular appliance model or features associated with the particular appliance model;

identifying the appliance model based upon the indicator;

communicating with a universal controller associated with the appliance, said controller including a memory having stored therein a plurality of operating parameters associated with a plurality of distinct appliance models; and

programming the controller to activate particular ones of the plurality of operating parameters that correspond to the appliance model designated by the indicator.

12. The method of claim 11, wherein reading the indicator constitutes scanning a bar code carried by the appliance.

13. The method of claim 12, wherein the bar code is affixed to a cabinet of the appliance.

14. The method of claim 11, wherein communicating with the controller constitutes wirelessly transmitting signals to the controller.

15. The method of claim 11, wherein the domestic appliance includes a cabinet having an associated user interface, and communicating with the controller constitutes inputting commands through control elements provided on the user interface, said control elements being operatively connected to the controller.
