Abstract

The disclosure relates to a composting device including a housing defining an interior with an access opening providing access to the interior, a composter bin located within the interior and in communication with the access opening, and a user operated door slidably mounted to the housing and electrically powered to automatically slide along a sliding path between opened and closed position.

First claim

What is claimed is:

1. A food composter comprising:
a housing having a front wall, a back wall, a top wall and a pair of side walls defining an interior; the top wall comprising an access opening providing access to the interior;
a composting bin located within the interior and having a fill opening in communication with the access opening;
a sliding lid assembly comprising:
an end plate defining the access opening;
a carriage slidably mounted to the end plate;
and a door horizontally mounted to a top of the carriage; the carriage horizontally moveable between the front wall and the back wall relative to the access opening; the door maintaining a horizontal position when moved between open/closed positions to selectively open/close the access opening;

a drive system operable in one of a forward or reverse direction and coupled to the carriage to move the door between the open/closed positions; and
a controller operably coupled to an actuator and the drive system to selectively energize the drive system when the actuator is triggered by a user; the controller configured to set a logical flag for reversing the drive system rotation between the forward and reverse directions when the actuator is energized by the user.

2. The food composter of claim 1 wherein the drive system comprises an electric motor operable by the actuator.

3. The food composter of claim 2 wherein the drive system comprises a rack and pinion drive, having a toothed rack mounted to the carriage and a toothed pinion gear enmeshed with the toothed rack and rotatably driven by the electric motor.

4. The food composter of claim 3 wherein the drive system further comprises a limit switch located at an end of movement position for the door for at least one of the open/closed positions, with the limit switch controlling power to the electric motor.

5. The food composter of claim 4 wherein there are two limit switches, one located at the end of movement for the open position and the other located at the end of movement for the closed position.

6. The food composter of claim 5 wherein the actuator comprises a switch located on the housing.

7. The food composter of claim 6 wherein the switch is located for at least one of hand or foot operation.

8. The food composter of claim 5 wherein the actuator comprises at least one of a motion or proximity sensor.

9. The food composter of claim 4 wherein the drive system further comprises a slider located on one side of the door and slidably coupling the door to the housing and the toothed rack is mounted to another side of the carriage opposite the slider.

10. The food composter of claim 1 wherein the drive system comprises a rack and pinion drive, having a toothed rack mounted to the carriage and a toothed pinion gear enmeshed with the toothed rack.

11. The food composter of claim 10 wherein the drive system further comprises a slider located on one side of the door and slidably coupling the door to the housing and the toothed rack is mounted to another side of the carriage opposite the slider.

12. The food composter of claim 1 wherein the actuator comprises a switch located on the housing.

13. The food composter of claim 12 wherein the switch is located for at least one of hand or foot operation.

14. The food composter of claim 1 wherein the actuator comprises at least one of a motion or proximity sensor.

15. The food composter of claim 1 wherein the top of the door is flush with the top of the side walls.

16. The food composter of claim 1 further comprising a funnel defining the access opening and providing access to the interior.

17. A food composter comprising:
a housing having a front wall, a back wall, a top wall and a pair of side walls defining an interior; the top wall comprising an access opening providing access to the interior;
a composting bin located within the interior and having a fill opening in communication with the access opening;
a sliding lid assembly comprising:
an end plate defining the top wall;
a carriage slidably mounted to the end plate;
and a door horizontally mounted to a bottom of the carriage between the side walls such that the top of the door defines a portion of the top wall; the carriage horizontally movable between the front wall and the back wall relative to the access opening; the door maintaining a horizontal position when moved between open/closed positions to selectively open/close the access opening; and

a drive system comprising a toothed rack mounted to the carriage, a toothed gear enmeshed with the toothed rack, a motor rotatably driving the toothed gear, and an actuator selectively actuating the motor; and
a controller operably coupled to an actuator and the drive system to selectively energize the drive system when the actuator is triggered by a user; the controller configured to set a logical flag for reversing the motor rotation between a forward and reverse direction when the actuator is energized by the user.

18. The food composter of claim 17 wherein the actuator comprises a switch located on the housing.

19. The food composter of claim 18 wherein the switch is located for at least one of hand or foot operation.

20. The food composter of claim 17 wherein the actuator comprises at least one of a motion or proximity sensor.
