Abstract

Abstract A pet toilet for receiving and then automatically flushing therefrom matter excreted by a pet. The toilet includes an enclosure having walls extending upwardly from a floor and having access means, such as an opening in a sidewall thereof, for a pet to enter and exit from the enclosure. A drainage outlet is provided in the floor and at least a portion of the upper surface of the floor is inclined downwardly toward the outlet. A flush system serves to spray water into the enclosure so that matter excreted therein by a pet is washed from the walls and floor of the enclosure so as to exit through the outlet. Water is supplied to the flush system from a suitable water source when a water supply valve is actuated. A photoelectric system serves to detect a pet entering the enclosure through the access thereto, and an electrical control responds to the photoelectric system for actuating the valve. The control circuit and photoelectric system are arranged so that the enclosure is flushed after the pet has exited. A water timer is provided for controlling the time duration that water is sprayed into the enclosure.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 186 words
A pet toilet comprising: a floor, means defining a walled enclosure extending upwardly from said floor and having a single access means for a pet to enter and exit from said enclosure; said floor having a drainage outlet therein and at least a portion of the upper surface of said floor being inclined downwardly toward said outlet; means for spraying water into said enclosure so that matter excreted therein by a said pet is washed from the walls and floor of said enclosure to said outlet; means for supplying water to said spraying means and including actuatable valve means for, when actuated, permitting water from a water source to be supplied to said spraying means; photoelectric means positioned for detecting a pet entering said enclosure through said single access means; and, control means electrically controlled by said photo-electric means for actuating said valve means in response to detection of a said pet, said control means includes electrically operated water timer means for timing a predetermined time duration of actuation of said valve means to thereby control the time duration that water is supplied to said enclosure.
Claim 2
Dependent Claim 186 words
A pet toilet comprising: a floor, means defining a walled enclosure extending upwardly from said floor and having a single access means for a pet to enter and exit from said enclosure; said floor having a drainage outlet therein and at least a portion of the upper surface of said floor being inclined downwardly toward said outlet; means for spraying water into said enclosure so that matter excreted therein by a said pet is washed from the walls and floor of said enclosure to said outlet; means for supplying water to said spraying means and including actuatable valve means for, when actuated, permitting water from a water source to be supplied to said spraying means; photoelectric means positioned for detecting a pet entering said enclosure through said single access means; and, control means electrically controlled by said photo-electric means for actuating said valve means in response to detection of a said pet, said control means includes electrically operated water timer means for timing a predetermined time duration of actuation of said valve means to thereby control the time duration that water is supplied to said enclosure.
Claim 3
Dependent Claim 54 words
A pet toilet as set forth in claim 1, wherein said access means is defined by a single opening in a sidewall of said enclosure and wherein said photoelectric means is positioned to provide a light beam which extends across said opening in the path of entrance into said enclosure by a said pet.
Claim 4
Dependent Claim 56 words
A pet toilet as set forth in claim 2, including means for mounting said photoelectric means to said walled enclosure so that said electric beam is positioned on the exterior side of said enclosure and just forwardly of said opening so as to be in the path of entrance to said enclosure by a said pet.
Claim 5
Dependent Claim 28 words
A pet toilet as set forth in claim 1, wherein said water timing means includes means for adjusting the said predetermined time duration of actuating said valve means.
Claim 6
Dependent Claim 47 words
A pet toilet as set forth in claim 1, including delay timing means controlled by said photoelectric means for timing a predetermined delay time in response to each pet detection and then providing an output signal for actuating said water timing means and, hence, said valve means.
Claim 7
Dependent Claim 21 words
A pet toilet as set forth in claim 5, wherein said delay means includes means for adjusting said predetermined delay time.
Claim 8
Dependent Claim 61 words
A pet toilet as set forth in claim 1, wherein said photoelectric means provide a first pulse when a pet enters said enclosure and a second pulse when said pet leaves said enclosure and two pulse counting means for counting said two pulses and then providing an output signal for energizing said water timer means and, hence, actuating said valve means.
Claim 9
Dependent Claim 132 words
A pet toilet as set forth in claim 1 wherein said access means is defined by a single opening in a sidewall of said enclosure, means for mounting said photoelectric means to said walled enclosure so that the light beam provided by said photoelectric means is located on the exterior side of said enclosure and just forwardly of said opening so as to be in the path of entrance to said enclosure by a said pet, said water timing means including means for adjusting the said predetermined time duration of actuating said valve means, and delay timing means controlled by said photoelectric means for timing a predetermined delay time in response to each pet detection and then providing an output signal for actuating said water timing means and, hence, said valve means.
