US 5,289,800 A · Waste odor eliminator cover for a cat waste box

Abstract

Minimizing or eliminating the amount of odor-laden air that leaves a cat litter box and circulates into the room is accomplished by the mixing of the cooler room air with the hotter air that rises from the animal's fecal matter to the top of the box and then out through a series of charcoal filters. This is achieved by having a dome cover (aesthetically or ornamentally designed to look like a bank) of approximately fourteen inches high, and twenty inches long by fifteen inches wide placed across the top of the litter box and/or removably fastened to same. The odor elimination or minimization starts with the cat's excretion of warm fecal matter in to the litter box or waste elimination system. As the warm, odor-laden air rises, it mixes in with the fresh cooler air entering into the dome cover from several (such as ten) designed slots on the outside of the dome cover. This diluted air automatically reduces odor by expanding the air flow to the top of the enclosure. At the top of the dome cover the diluted air enters outlets that have charcoal filters therein, thereby purifying the air as it passes through the filters and into the general air in the room in which the litter box or waste elimination system is placed.

A waste odor eliminator cover for a cat waste box, said cover being approximate]y fourteen inches high, twenty inches long and fifteen inches wide and having a substantially flat bottom surface so as to be supported across the top of a cat litter box or a cat waste elimination system, said cover having a top, walls at its sides and at its rear and an entryway at its front for the cat to enter the litter box or elimination system, said sides and rear of the cover having a totality of air slots in same which permit the entry of outside air into the cover near its bottom so as to mix with the odor-laden warm air arising from the cat's excretory functions and to force by convection currents the warm air to rise toward the top of the cover, said top of the cover having charcoal filters and air outlets therein, whereby the odor-laden air is purified as it passes into the room in which the litter box or waste elimination system is placed.

A waste odor elimination system for cats comprising in combination:

a. a substantially rectangular top tray compartment;
b. a substantially rectangular bottom tray assembly;
c. a granular material on the bottom of the top tray compartment;
and
d. a waste odor eliminator cover supported across the top surface of the top tray compartment, said cover being approximately fourteen inches high, twenty inches long and fifteen inches wide and having a substantially flat bottom surface so as to be supported across the top surface of the top tray compartment of the waste odor elimination system, said cover having a top, walls at its sides and at its rear and an entryway at its front for the cat to enter the elimination system, said sides and rear of the cover having a totality of air slots in same which permit the entry of outside air into the cover near its bottom so as to mix with the odor-laden warm air arising from the cat's excretory functions and to force by convection currents the war air to rise toward the top of the cover, said top of the cover having charcoal filters and air outlets therein, whereby the odor-laden air is purified as it passes into the room in which the waste odor elimination system is placed.
