Automated litter device

1. An automated litter device having:

a) a base; and

b) a chamber configured for retaining a litter and rotatably supported by the base, wherein the chamber includes:

i) an entry opening so that an animal can enter and exit the chamber;

ii) a waste opening configured so that an animal waste passes through the waste opening into the base upon rotation of the chamber; and

iii) a rotational axis about which the chamber rotates during a cleaning cycle; and

c) a litter dispenser in communication with the chamber and configured to retain a clean and unused litter, wherein the litter dispenser includes:

i) a chute configured to transfer the clean and unused litter from the litter dispenser into the chamber, wherein the chute is located at a rear of the chamber generally opposite of the entry opening and is at least partially aligned with the rotational axis of the chamber.

2. The automated litter device of claim 1 , wherein the litter dispenser is affixed to the base, a bonnet which at least partially covers the chamber, or both.

3. The automated litter device of claim 1 , wherein the litter dispenser is in fluid communication with an interior of the chamber.

4. The automated litter device of claim 3 , wherein the litter dispenser is located generally opposite of the entry opening.

5. The automated litter device of claim 1 , wherein the litter dispenser includes one or more dispensing devices which are configured to retain the clean and unused litter within the litter dispenser during a resting mode.

6. The automated litter device of claim 5 , wherein the one or more dispensing devices are configured to transfer a portion of the clean and unused litter within the litter dispenser to the chamber during a refill cycle of the litter dispenser.

7. The automated litter device of claim 6 , wherein the one or more dispensing devices include one or more paddles configured to rotate during the refill cycle to transfer the clean and unused litter.

8. The automated litter device of claim 7 , wherein the one or more paddles include a plurality of fins radially projecting from a hub.

9. The automated litter device of claim 8 , wherein the one or more paddles are in communication with one or more drive sources.

10. The automated litter device of claim 9 , wherein the one or more drive sources includes a motor.

11. The automated litter device of claim 10 , wherein the one or more drive sources are in communication with one or more sensors; and

wherein the one or more sensors are configured to detect a level of the litter within the chamber.

12. The automated litter device of claim 1 , wherein the automated litter device includes one or more sensors adjacent to the entry opening and positioned to have a line of sight into a hollow interior of the chamber such that the one or more sensors are adapted to sense a presence of the animal within the chamber, a presence of the animal waste in a waste bin, a level of the litter in the chamber, a position of the chamber relative to the base, or any combination thereof.

13. The automated litter device of claim 12 , wherein the one or more sensors includes one or more mass sensors, capacitive sensors, infrared sensors, laser sensors, ultrasonic sensors, membrane sensors, radio frequency (RF) admittance sensors, conductive sensors, optical interface sensors, microwave sensors, or combination thereof.

14. The automated litter device of claim 12 , wherein the one or more sensors or one or more other sensors are configured to detect a presence of the animal within the waste bin.

15. The automated litter device of claim 1 , wherein the automated litter device includes a bezel about the entry opening.

16. The automated litter device of claim 15 , wherein one or more sensors are assembled to the bezel.

17. The automated litter device of claim 1 , wherein the chamber includes a track generally opposite the entry opening for rotating the chamber about the rotational axis.

18. An automated litter device having:

a) a base; and

b) a chamber configured for retaining a litter and rotatably supported by the base, wherein the chamber includes:

i) an entry opening so that an animal can enter and exit the chamber;

ii) a waste opening configured so that an animal waste passes through the waste opening into the base upon rotation of the chamber; and

iii) a rotational axis about which the chamber rotates during a cleaning cycle; and

c) a litter dispenser in communication with the chamber wherein the litter dispenser includes:

i) a hopper configured to retain a clean and unused litter;

ii) dispensing device configured to retain the clean and unused litter within the hopper during a resting mode and configured to transfer a portion of the clean and unused litter within the hopper toward the chamber during a refill cycle; and

iii) a chute configured to transfer the clean and unused litter from the dispensing device into the chamber; wherein the chute is located at a rear of the chamber generally opposite of the entry opening and is at least partially aligned with the rotational axis of the chamber.

19. The automated litter device of claim 18 , wherein the dispensing device includes one or more paddles configured to rotate during the refill cycle to transfer the clean and unused litter; and

wherein the one or more paddles include a plurality of fins radially projecting from a hub.

20. The automated litter device of claim 18 , wherein the automated litter device includes one or more sensors adjacent to the entry opening and positioned to have a line of site into a hollow interior of the chamber such that the one or more sensors are adapted to sense a presence of the animal within the chamber, a presence of the animal waste in a waste bin, a level of the litter in the chamber, a position of the chamber relative to the base, or any combination thereof.
