Abstract

A food waste disposer system has a food waste disposer and a rechargeable power source that provides power to a motor of the food waste disposer. In an aspect, the motor is a permanent magnet DC motor having a nominal no-load speed in the range of 15,000 revolutions per minute to 30,000 revolutions per minute and the motor section includes a gear reduction mechanism. In an aspect, the food waste disposer system includes a power module that communicates wirelessly with a wireless activator. In an aspect, a stopper receivable in an inlet of the food waste disposer includes or is couplable to a power source which in an aspect is a rechargeable power source and in an aspect, is disposed in a housing of the stopper. In an aspect, the stopper includes a cord for coupling the stopper to the power source which is a source of AC power.

First claim

What is claimed is:

1. A food waste disposer system comprising:
a food waste disposer including a food conveying section, a motor section and a grind and discharge section, the food conveying section conveying food waste to a grind section of the grind and discharge section;
the grind section including a grind mechanism, the grind mechanism including a rotatable shredder plate assembly, the rotatable shredder plate assembly rotated by a motor of the motor section;
the motor comprising a permanent magnet direct current motor having a nominal no-load speed in the range of 15,000 revolutions per minute to 30,000 revolutions per minute;

the motor section including a gear reduction mechanism coupling the rotor shaft to the rotatable shredder plate assembly, the gear reduction mechanism having an input/output gear reduction ratio in a range of 4.3-30 to 1 wherein the nominal no-load speed of the motor and the input/output ratio of the gear reduction mechanism are configured so that an output shaft of the gear reduction mechanism rotates in a range of 1,000 revolutions per minute to 3,500 revolutions per minute when the motor is running at its nominal no-load speed; and
a rechargeable power source that provides power to the motor.

2. The food waste disposer system of claim 1 wherein the gear reduction mechanism includes an impact mechanism.

3. The food waste disposer system of claim 2 wherein the impact mechanism is configured to activate when the rotating shredder plate assembly is stopped in a jam condition.

4. The food waste disposer system of claim 2 including a flywheel disposed between and coupled to the gear reduction mechanism and the rotatable shredder plate assembly.

5. The food waste disposer system of claim 1 including a flywheel disposed between and coupled to the gear reduction mechanism and the rotatable shredder plate assembly.

6. The food waste disposer system of claim 1 wherein the gear reduction mechanism is an angled gear reduction mechanism having an offset angle and the motor is offset to a side of the food waste disposer at the offset angle to the output shaft of the gear reduction mechanism.

7. The food waste disposer system of claim 1 wherein the permanent magnet direct current motor is any of a motor having a wound rotor and a stator with permanent magnets and a brushless direct current motor having a wound stator and a rotor with permanent magnets.

8. The food waste disposer system of claim 1 wherein the rechargeable power source is at least one of a battery, ultra-capacitor and an ultra-capacitor battery hybrid.

9. The food waste disposer system of claim 1 including a charger coupled to the rechargeable power source.

10. The food waste disposer of claim 9 wherein the charger is a wireless charger.

11. The food waste disposer system of claim 1 including a power module and a wireless activator;
the power module wired to the motor, the power module having the rechargeable power source received therein, the power module further having a wireless communication unit;
the wireless activator including a wireless communication unit;
the wireless communications unit of the wireless activator and the wireless communications unit of the power module in wireless communication with each other;
the wireless activator including an on/off switch; and
the power module turning the food waste disposer on and off in response to actuation of the on/off switch of the wireless activator wherein upon the on/off switch of the wireless activator being actuated, the wireless communication unit of the wireless activator communicating wirelessly with the wireless communication unit of the power module to send a message that the on/off switch of the wireless activator was actuated.

12. The food waste disposer system of claim 11 , wherein if the food waste disposer is off when the on/off switch of the wireless activator is actuated, the power module determines if a reset is required and upon determining that a reset is required, sends a message to the wireless activator that the reset is required and the wireless activator illuminates a reset indicator upon receipt of the message that the reset is required and the power module does not turn the food waste disposer on.

13. The food waste disposer system of claim 12 wherein upon determining that the reset is not required, the power module measures a voltage level of the rechargeable power source and determines whether the voltage level of the battery is sufficient to run the food waste disposer and turns the food waste disposer on only if the voltage level of the rechargeable power source is sufficient to run the food waste disposer.

14. The food waste disposer system of claim 13 wherein after turning the food waste disposer on, the power module turns the food waste disposer off upon the on/off switch of the wireless activator being actuated or after a lapse of a predetermined period time.

15. The food waste disposer system of claim 14 wherein the on/off switch is an on/off button and the power module toggles the food waste disposer on and off in response to the on/off button being pressed.

16. The food waste disposer system of claim 14 wherein the wireless activator includes a rechargeable power source voltage level display and upon turning the food waste disposer off, the power module sends the measured rechargeable power source voltage level to the wireless activator and the wireless activator displays the measured battery voltage on the battery voltage level display.

17. The food waste disposer system of claim 16 wherein the power module also includes a rechargeable power source voltage level display on which it displays the measured rechargeable power source voltage level.

18. The food waste disposer system of claim 11 wherein the power module also includes an on/off switch and the power module also turns the food waste disposer on and off upon the on/off switch of the power module being actuated.

19. The food waste disposer system of claim 18 wherein the on/off switch is an on/off button and the power module toggles the food waste disposer on and off in response to the on/off button being pressed.

20. The food waste disposer system of claim 11 wherein the rechargeable power source is at least one of a battery, ultra-capacitor and an ultra-capacitor battery hybrid.

21. The food waste disposer system of claim 11 including a charger coupled to the rechargeable power source.

22. The food waste disposer system of claim 21 wherein the charger is a wireless charger.

23. The food waste disposer system of claim 11 wherein the rechargeable power source is removably receivable in the power module.

24. The food waste disposer system of claim 11 wherein the power module is disposed remotely from the food waste disposer.

25. The food waste disposer system of claim 11 wherein the power module is mounted on or in the food waste disposer.

26. The food waste disposer system of claim 1 including a stopper having a body configured for receipt in a food waste inlet of the food waste disposer, the rechargeable power source disposed in the body of the stopper and providing power to the motor of the food waste disposer when the stopper is received in the food waste inlet of the food waste disposer.

27. The food waste disposer system of claim 26 wherein the rechargeable power source is at least one of a battery, an ultra-capacitor an
