Abstract

A control system is provided for controlling the operation of a plurality of associated appliances. The appliances are individually powered from separate power sources. A single control panel is mounted on one of the appliances and includes selection switches for operator input of cycle information corresponding to each of the appliances and also includes display apparatus. A single controller is in circuit communication with the power supply of one appliance, the selection switches and the display apparatus and outputs data signals to a driver which outputs data signals to control operation of the appliances and the display apparatus. The driver is operable for outputting a series of multiplexed data signals on outputs to the appliances, the display apparatus and the selection switches so that the controller is operable for effecting selective and independent operation of one or concurrent and independent operation of more than one of a plurality of associated appliances. Low voltage cabling is provided between the controller and each appliance for carrying data signals to each appliance.

Claims

1. A control system for controlling the operation of a plurality of associated appliances, comprising:

power supply means providing line current to each of said appliances;

control panel means including selection means for inputting cycle information corresponding to each of said appliances and further including display means for each of said appliances;

a single control means including microcontroller means in communication with said selection means and said power supply means and operable for controlling each of said appliances through independent cycles of operations; and

low voltage interconnecting means between said control means and each of said appliances for carrying operational data signals from said control means to each of said appliances to effect selective and independent operation of one or concurrent and independent operation of more than one of said appliances.

2. A control system as defined in claim 1 wherein said control panel means is mounted on one of said appliances.

3. A control system as defined in claim 1 wherein said low voltage interconnecting means includes low voltage cabling between said control means and at least one of said appliances.

4. A control system for controlling the operation of a plurality of associated appliances, comprising:

power supply means for providing line current to each of said appliances;

control panel means associated with at least one of said appliances including selection means for inputting cycle information corresponding to each of said ppliances and further including display means for each of said appliances;

a single control means including microcontroller means in communication with said selection means and said power supply means and operable for controlling each of said appliances through independent cycles of operation, said control means further including driver means for receiving data signals from said microcontroller means and for outputting data signals to each cf said appliances and said display means for effecting selective and independent operation or modification of operation of one or concurrent and independent operation or modification of operation of more than one of said appliances; and

low voltage interconnecting means between said control means and each of said appliances for carrying said data signals to each appliance.

5. A control system for controlling the operation of a plurality of associated appliances, comprising:

power supply means for providing line current to each of said appliances;

control panel means associated with one of said appliances including selection means for inputting cycle information corresponding to each of said appliances and further including display means for each of said appliances;

a single control means including microcontroller means in communication with said selection means and said power supply means and operable for controlling each of said appliances through independent cycles of operation, said control means further including driver means for receiving data signals from said microcontroller means and for outputting data signals to control operation of said appliances and said display means, said driver means having at least a pair of outputs and multiplexing means and operable for outputting a series of multiplexed data signals on said pair of outputs to said appliances, display means and selection means whereby said control means is operable for effecting selective and independent operation of one or concurrent and independent operation of more than one of said appliances; and

low voltage interconnecting means between said control means and each of said appliances for carrying said data signals to each appliance.

6. A control system as defined in claim 5 wherein said control means further includes circuit means for monitoring the output of at least one of said pair of driver outputs to detect the presence of said data signal and for deenergizing said control means if said data signal is not present.

7. A control system as defined in claim 6 wherein said low voltage interconnecting means includes low voltage cabling between said control means and the other of said plurality of associated appliances.

8. A control system for controlling the operation of a plurality of associated appliances, comprising:

power supply mean for providing line current to each appliance;

control panel means mounted on one of said appliances including selection means for inputting cycle information corresponding to each of said appliances and further including display means for each of said appliances;

a single control means including microcontroller means in communication with said selection means and said power supply means and operable for controlling each of said appliances through independent cycles of operation, said control means further including driver means for receiving data signals from said microcontroller means and for outputting data signals to control operation of each of said appliances and said display means, said driver means having at least a pair of outputs and multiplexing means and operable for outputting a series of multiplexed data signals on said pair of outputs with a first data signal driving said display means for one appliance and updating the operating program of each appliance and a second data signal driving said display means for the other appliance and servicing said selection means; and

low voltage interconnecting cabling between said control means and each cf said appliances for carrying said data signals to each appliance.

9. A control system as defined in claim 8 wherein said control panel means and said control means are mounted on one of said appliances.
