Field of Invention

The present invention relates to the field of pet toilets. More specifically the present invention relates to an automatic, semi - portable, enclosed pet toilet system and method of cleaning without human intervention.

Background of the Invention

Pets have become an integral part of many households across the world. Many houses are designed to accommodate pets. However, tackling hygiene and cleanliness issues at homes with pet animals running around have become challenging. It is further challenging to entertain pets in apartments where there are no backyards for the pets to defecate. To address these issues many indoor pet toilets have been designed. The pet toilets are aimed at minimizing the mess created by pets at homes due to the lack of open spaces. The conventional pet toilets had litter boxes, which were then replaced by basins that needs to be regularly cleaned by the owners after the pet uses them. These methods however had many drawbacks. One such main issue is the presence of a permanent stench in the air caused due to the pets’ excretion when not cleaned immediately. This also brought out many sanitation issues, especially within small, enclosed houses and houses with children.

Further improvements were made to the pet toilets and certain solutions such as indoor faux grass was introduced where the faux grass resembled the natural grass, and the pets were encouraged to use them for excretion. Also, grated pet toilets came into use where the pets excreted on a tray fitted with a grate. But these improvements did not help in eliminating the odor constantly present indoors. It only resulted in usage of lot of cleaning agents which proved to be time consuming and not environment friendly.

The need for better excretion system for pets increased and pet toilets with flush mechanism were introduced similar to the regular toilet systems at homes. The pet toilets again needed human’s intervention for flushing and cleaning of the toilets. There are some pet toilets in the market with auto cleaning system, but they are very difficult to move around as they must be fixed in a place due to its size and complex operational methods. Further in the presence of more than one pet animal at home, it becomes difficult to restrict the usage of the toilet to one pet at a time and it becomes chaotic inside the toilet when two pets try to use it at the same time. Further, it puts the safety of the pets at risk when the enclosed toilet system closes after the pet animal when the toilet is in use, as the owner wouldn’t be aware of what is happening in the pet toilet. However, many existing pet toilets’ systems have been designed to address the needs of the pet animals to defecate in a friendly environment which are provided with easy cleaning methods.

South Korean patent application KR20110135527A relates to an automatic pet flush toilet, the sensor 520 of the upper frame 300 detects the entry and exit of the dog, the control device 500 is operated to automatically water the water of the dog's feces in the plumbing facility 400 By discharging urine to the drain immediately by spraying, it prevents the smell of stool, solves the difficulty of cleaning every time, prevents the unsanitary environment caused by the feces of dogs, and reduces the water consumption used to treat the feces. It minimizes the use of various cleaning agents and eliminates excessive consumption such as pulp material pads and toilet paper.

US patent application US8863693B2 animal toilet disclosed herein is equipped with a permeable toileting surface, a catchment surface underlying the toileting surface to collect and channel liquids, and a drain. The toileting surface may be equipped with a rinsing element to rinse wastes from the toileting and catchment surfaces. The dram may be further equipped with tubing to convey the liquids to a convenient disposal location. The animal toilet may be equipped with a moving toileting surface, which results in improved rinsing, and potential solid waste collection. In all embodiments, absorbent material may be used in place of permeable material for the toileting surface, which may not require any rinsing. The solid waste disposal may be automated through the use of rinse water and disposal tubing routed to the proper disposal location.

US patent application US6457435B 1 discloses a pet toilet for use indoors. The pet toilet has electronic sensing detection devices built within its parallel walls of housing. Such electronic sensing detection devices determine the pet's entrance and leaving. Once the pet leaves the housing, the system flushes. The pet toilet is attached to conventional household drains. The water is supplied by a water supply line and feeds such water through water distribution lines which are embedded in the parallel walls of the housing. The invention also encompasses a manual flush button in case the pet owner wishes to flush the system manually, and also the housing comprises a water spray assembly to effectively clean the housing with a hand-held spray device.

US patent application US3603290 discloses a pet is trained to excrete upon a tray and to reinforce the training, the pet is given a reward for excreting, such as food from a dispenser operated by the pet. To prevent the pet from cheating, a urine sensor and a feces sensor are located on the tray and an interlock circuit connects them to the dispenser, preventing operation of the dispenser unless atleast one of the sensors detects the presence of excrement. To reduce odors, a flushing flow of water may be provided and the human toilet bowl is utilized to receive the animal excrement and the flushing flow. Since water flow is available to the tray, the sensors may be water powered, and the interlock circuit may be water powered.

US patent application US4729342 discloses an automatic pet toilet has a housing defining a generally closed chamber having a floor and side walls, one of the latter having an opening through which the pet can pass. A door is displaceable on the housing between a closed position blocking the opening and an open position clear of same by means of a door drive motor. A closed-door switch on the housing generates an output only when the door is in its closed position. Floor and wall sprays respectively directed in the chamber at the floor and walls of the chamber are supplied with wash liquid, usually water, by a valve connectable to a source of pressurized liquid. A drain in the floor and a chopper connectable to a waste line receive material washed by the sprays from the walls and floor, comminute the material, and feed it to the waste line. A sensor emits an output when the pet is within the chamber and a controller connected to the chopper, switch, sensor, motor, and valve closes the door and then opens the valve and operates the chopper when a pet has entered and left the chamber with interruption of the beam while in the chamber, and thereafter closes the valve, stops the chopper, and opens the door.

Another US patent application US6561131 discloses a pet toilet preferably includes a litter chamber with a sculptured end and a tapered end. A mechanism preferably moves the litter chamber to a vertical position to meet a stationary vertical lid for cleaning. When the lid and the litter chamber are together, an airtight seal is created. The sculptured end is at the top of the litter chamber and the tapered end is at the bottom of the litter chamber when the litter chamber is in a vertical position. A blade, found at the lowest point of the tapered end, cuts and agitates the waste collected by gravity at this lowest point. Water, added to the vertical litter chamber through an inlet and holes around the blade, floats the waste to the top of the litter chamber. The sculptured end catches floating waste and directs it out of the pet toilet through an exit pipe.

Although all of the prior-arts are effective in their intended purposes, the existing devices and systems do not provide an economical, easy and smooth level of operation, wherein in the presence of multiple pet animals, the usage of the toilet system proves to be complicated. Further the prior art does not provide portability of the toilet system in the existing designs.

Example 1: The pet toilet system comprises of a ramp (11), an outer sensor (12), an inner sensor

(15), a door(14), a swiveling platform (16), sprinkler line and an inlet line (19) in the upper chamber (22). A control box (21) connected to the sensors (12, 15), platform (16), pipes etc., is fitted under the ramp (11). A lower chamber (23) comprises of a sewage tank (30) fitted with a sewage pipe (20). The pet toilet system may also consist of steps (25) instead of ramp (11) to enter the toilet system. A pet animal approaches the toilet system, and the outer sensor (12) (in front of the door) senses the pet and un-locks the door (14). The pet animal then flips the door (14) and enters and then crosses the inner sensor (15) (behind the door in the system) which then senses and locks the door (14) thus ensuring and preventing any other pet animal from entering the toilet system while the first pet animal is using the toilet. After the pet animal has excreted on the platform

(16) of the system and approaches the exit, the inner sensor (15) senses the pet animal and un-locks the door (14). The pet animal flips the door (14) and exits. The outer sensor (12) then senses the dog exiting the toilet and locks the front door (14).

The automated cleaning process of the system is then carried out. The cleaning process entails the entire floor/ platform (16) of the toilet swiveling by 180° (upside position) and at the same time the various water sprinklers (18) start spraying water to all the surfaces that can possibly be soiled including the platform (16) surface and walls of the system. Once a thorough washing is carried out for a predetermined amount of time, the platform (16) swivels back by 180° (upright position) and is locked in place and ready to be used. Outer sensor (12) is then activated to sense and allow the entry of the pet animal once again. While the cleaning of the system is in progress the sensors (12, 15) ensure that the door of the system is locked thus preventing the entry of the pet animal. The transparent upper walls of the enclosure of the system ensures that the pet animal can be observed while it is inside the system. The cleaning of the system and swivel functions of the platform (16) can also be carried out manually, independent of the automation (i.e., bypassing the sensors).

Example 2: The pet toilet system can be used as an outdoor unit, wherein the system comprises of a ramp (11) or steps (25), an outer sensor (12), an inner sensor (15), a door (14), a swiveling platform (16), sprinkler line and an inlet line (19) in the upper chamber (22). A control box (21) connected to the sensors (12, 15), platform (16), pipes etc., is fitted under the ramp (11). A lower chamber (23) comprises of a sewage tank (30) fitted with a sewage pipe (20). The system is further housed in an enclosure comprising of a pipeline (29) running around the housing. The enclosure is further provided with an over-head water tank (26), which serves to provide insulation from above during winter. The water tank (26) is further fitted with an inlet pipe (19) and a float valve (27) to automatically keep the water tank full and prevent overflow. The water tank has an embedded heater (32) to keep the water warm as required. The pipeline (29) which runs all around the housing in circles also serves as heating coils to keep the entire enclosure warm. The pipeline (29) is provided with a pump/ turbine (30) to keep the water flowing throughout. The pipeline (29) is fitted with a thermostat (28) on the return line just before water re-enters the tank which in turn controls the heater (32) in the tank.

The pipeline running around the enclosure keeps the system warm, which enables the pet animal to use the toilet system outdoors even during winter. After the pet animal excretes on the platform (16) of the system, the automated cleaning process of the system is then carried out. wherein the entire floor/ platform (16) of the toilet swivels by 180° (upside position) and at the same time the various water sprinklers (18) start spraying water to all the surfaces that can possibly be soiled including the platform (16) surface and walls of the system. Once a thorough washing is carried out for a predetermined amount of time, the platform (16) swivels back by another 180° (upright position) and is locked in place and ready to be used. The waste and debris from the cleaning is collected in the sewage tank (31) which is the expelled through the sewage line (20). The cleaning of the system and swivel functions of the platform (16) can also be carried out manually, independent of the automation (i.e., bypassing the sensors).
