Abstract

A touch pad control information system for a food waste disposer is disclosed. The touch pad is mountable to a wall or countertop near the food waste disposer. The touch pad preferably includes switches which allow the user to select from a plurality of disposer functions, and light emitting diodes (LEDs) or other graphic display to indicate one of a plurality of statuses for the disposer. The touch pad is coupled to the disposer by a wire bus or by wireless means.

Claims

1. A food waste disposer system, comprising:

a food waste disposer having a motor and a controller coupled to the motor; and

a control panel in wireless communication with the controller having a plurality of switches that can be depressed by a user to choose from a plurality of functions that the food waste disposer can perform, upon the user depressing a switch, the control panel wirelessly communicating to the controller which switch the user depressed, the controller controlling the food waste disposer in response to the wireless communication from the control panel to perform the function associated with the switch depressed by the user.

2. The system of claim 1 wherein the plurality of functions include a plurality of motor speeds, the controller controlling the speed of the motor to a speed selected by which switch the user depresses.

3. The system of claim 2 wherein the plurality of functions include a soft start mode, a rinse mode, an optimized grinding mode, and an idle mode.

4. The system of claim 1 wherein the control panel includes a touch sensitive area that includes the plurality of switches.

5. The system of claim 4 wherein the control panel includes a status indicator area including a plurality of status indicators for indicating status of a plurality of status conditions of the food waste disposer.

6. The system of claim 5 wherein the status conditions include a plurality of conditions detected by the controller that communicates their status wirelessly to the control panel, the control panel controlling one of the status indicators for each such status condition in response to the wireless communication from the controller, the status indicators including a status indicator for each status condition detected by the controller.

7. The system of claim 6 wherein the conditions detected by the controller include a jam condition, presence of water in the food waste disposer, presence of metal in the food waste disposer, and the presence of power to the food waste disposer.

8. The system of claim 5 wherein the status indicators include an audible indicator.

9. The system of claim 5 wherein the status indicators include a textual display.

10. The system of claim 5 wherein the status indicators include a light.

11. The system of claim 5 wherein the status conditions include the function chosen by the user.

12. The system of claim 1 wherein the control panel includes a plurality of status indicators for indicating status of a plurality of status conditions of the food waste disposer.

13. The system of claim 12 wherein the status indicators include an audible indicator.

14. The system of claim 12 wherein the status indicators include a textual display.

15. The system of claim 12 wherein the status indicators include a light.

16. The system of claim 12 wherein the status conditions include the function chosen by the user.

17. The system of claim 12 wherein the status conditions include a plurality of conditions detected by the controller that communicates their status wirelessly to the control panel, the control panel controlling one of the status indicators for each status condition in response the wireless communication from the controller, the status indicators including a status indicator for each condition detected by the controller.

18. The system of claim 17 wherein the conditions detected by the controller include a jam condition, presence of water in the food waste disposer, presence of metal in the food waste disposer, and the presence of power to the food waste disposer.

19. The system of claim 1 wherein the control panel is mounted to a countertop or in a wall located proximate to the food waste disposer.

20. The system of claim 19 wherein the control panel includes an electrical box and an electrical box cover, the electrical box measuring approximately 1.75 inches×

2.75 inches and the electrical box cover measuring 2.75×

4.5 inches.

21. The system of claim 1, including a metal sensor coupled to the controller that detects the presence of a metal object in a grind chamber of the food waste disposer, the control panel including a status indicator for indicating the presence of a metal object in the grind chamber, the controller communicating wirelessly with the control panel to activate the status indicator that indicates the presence of the metal object in the grind chamber upon the metal sensor detecting the presence of the metal object in the food waste disposer.

22. The system of claim 21 wherein the food waste disposer includes a stationary shredder ring and a rotatable grinding plate rotatable by the motor, the metal detector responsive to inductive coupling between the grinding plate and the shredder ring and detecting whether a metal object is in the food waste disposer based on the inductive coupling.

23. The system of claim 1, further including a water solenoid activated by the controller when the food waste disposer is started.

24. The system of claim 1, further including a lock cover switch that couples an AC input of the food waste disposer to a source of AC voltage in response to a cover being situated in a drain opening of the food waste disposer.
