PET SANITATION DEVICE

摘要

A pet sanitation device provides a litter-containing basket in a housing. After a pet uses the device, the housing and basket are filled with water to dissolve waste in the litter, thus producing wastewater. The basket is then caused to spin about a central axis in the housing, and the spinning motion produces centrifugal forces that force the wastewater outward from the basket and into the space between the basket and the housing. The wastewater is drained from the housing, leaving the device ready for a subsequent use.

主权项

1. A pet sanitation device comprising:
a) an outer housing comprising a water-retaining sidewall and a water-retaining floor with a drain effective to drain water from the housing; b) an inner basket positioned within the outer housing and spaced apart from said housing, the basket comprising a bowl with openings to allow water to drain from the sides and bottom of the basket upon rotation of the basket, and defining a central axis; c) a motor effective for spinning the basket about its central axis; d) a washable particulate material contained in the basket; e) a scraper positioned adjacent an inner wall of the basket; f) a water inlet effective to provide water to the interior of the basket; g) a sensor effective to detect the presence of a pet in the basket and also effective to detect the absence of a pet in the basket. h) a controller to receive a signal from the sensor indicating that a pet has been present in the basket and has subsequently left the basket, and subsequently to cause the motor to rotate the basket at a speed effective to cause water to be driven by centrifugal forces to the space between the inner basket and the outer housing.
