Abstract

An automated litter device having: a base; and a chamber configured for retaining a litter and rotatably supported by the support base, wherein the chamber includes: an entry opening so that an animal can enter and exit the chamber; and a waste opening generally opposing the entry opening configured so that an animal waste passes through the waste opening into the base upon rotation of the chamber; wherein the automated litter device includes one or more of: i) one or more sensors located adjacent to the entry opening which are adapted to sense the presence of the animal within the chamber, the presence of the waste in the base, a level of litter in the chamber, a position of the chamber relative to the base, or any combination thereof; ii) a filtering system configured for reducing, eliminating, and/or preventing, malodors building in the base; and/or iii) a litter dispenser in communication with the chamber to transfer some of the litter to the chamber.

Claims (29)

1 . An automated litter device having:

a) a chamber configured for retaining a litter and configured to rotate during a cleaning cycle, wherein the chamber includes:

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

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

b) one or more sensors located adjacent to the entry opening, such as to be disposed at a periphery of the entry opening, and wherein the one or more sensors are adapted to sense an entry of the animal into the chamber, an exit of the animal from the chamber, a presence of the animal within the chamber, a presence of the waste, a level of the litter in the chamber, a position of the chamber, or any combination thereof.

2 . The automated litter device of claim 1 , wherein the one or more sensors are able to sense presence, measure a distance, measure a displacement, detect a position relative to one or more components of the automated litter device, or any combination thereof.

3 . The automated litter device of claim 1 , wherein the one or more sensors include one or more infrared sensors, laser sensors, ultrasonic sensors, radio frequency (RF) admittance sensors, conductive sensors, optical interface sensors, microwave sensors, or a combination thereof.

4 . The automated litter device of claim 3 , wherein the one or more sensors include the one or more laser sensors.

5 . The automated litter device of claim 1 , wherein the one or more sensors are a plurality of sensors.

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

7 . The automated litter device of claim 6 , wherein the one or more sensors are assembled to the bezel.

8 . The automated litter device of claim 7 , wherein the one or more sensors are located on the bezel to have a line of sight into the chamber, the waste opening, or both when aligned with a waste drawer.

9 . The automated litter device of claim 1 , wherein at least one of the one or more sensors has a line of sight onto a majority of an exposed surface of the litter so as to detect the presence of the animal within the chamber, the level of the litter in the chamber, or both.

10 . The automated litter device of claim 1 , wherein during the cleaning cycle, the chamber is configured to rotate such that the waste transfers from the chamber into a waste receptacle outside of the chamber.

11 . The automated litter device of claim 10 , wherein the automated litter device includes a base which rotatably supports the chamber.

12 . The automated litter device of claim 11 , wherein the waste receptacle is supported by the base.

13 . The automated litter device of claim 7 , wherein the automated litter device includes a bonnet which at least partially covers the chamber and the bezel is affixed to the bonnet.

14 . The automated litter device of claim 13 , wherein the automated litter device includes a base; and the base has the bonnet affixed thereto.

15 . The automated litter device of claim 14 , wherein the bezel is affixed to the base.

16 . The automated litter device of claim 1 , wherein the one or more sensors are adapted to sense the entry of the animal into the chamber, the exit of the animal from the chamber, the presence of the animal within the chamber, or any combination thereof.

17 . An automated litter device having:

a) a base supporting a waste receptacle;

b) a chamber configured for retaining a litter, rotatably supported by the base, and configured to rotate during a cleaning cycle, wherein the chamber includes:

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

c) one or more sensors located adjacent to the entry opening such as to be disposed at a periphery of the entry opening, and wherein the one or more sensors are adapted to sense an entry of the animal into the chamber, an exit of the animal from the chamber, a presence of the animal within the chamber, or any combination thereof.

18 . The automated litter device of claim 17 , wherein the one or more sensors include one or more infrared sensors, laser sensors, ultrasonic sensors, radio frequency (RF) admittance sensors, conductive sensors, optical interface sensors, microwave sensors, or a combination thereof.

19 . The automated litter device of claim 17 , wherein the one or more sensors are affixed to the chamber, a bezel, a bonnet, or any combination thereof.

20 . The automated litter device of claim 17 , wherein the automated litter device includes a bezel about the entry opening and statically affixed to one or more components which house and/or support the chamber; and

wherein the one or more sensors are assembled to the bezel such as to be adjacent to the entry opening.
