Description

Technical Field

[0001] The present disclosure relates to a toilet for pets, and more specifically, to an automatic flushing toilet for pets using a pressurized water flushing and discharging system.

Background Art

[0002] Automatic flushing toilets for pets are known. Automatic flushing toilets for pets are particularly useful in urban areas where it is difficult for pet owners to find a suitable outdoor location for their pets to excrete feces and urine. Ideally, pet feces and urine are discharged into the local sewage system. U.S. Patent No. 8,434,426 discloses an automatic toilet for pets having a concave bowl and a central discharge hole. Flushing and discharging are by gravity. The concave bowl has a grid, which is undesirable as it is difficult to clean and can retain particulate matter. U.S. Patent Publication No. 2017 / 0245459 discloses an automatic toilet for pets having a concave bowl and a central discharge hole. This automatic toilet for pets also flushes and discharges by gravity. The concave bowl is somewhat slippery and a pet may step into the central discharge hole, which is undesirable. U.S. Patent Publication No. 2015 / 0053140 discloses a device for cleaning a toilet for pets. The toilet for pets uses a mesh grid in the bowl. Urine passes through the mesh grid into a container. Feces remain on the mesh and are removed by hand. The container is cleaned by a water pump but discharges by gravity. Gravity-based flushing and discharging are not very effective for removing feces from the bowl, grid, or mesh.

Mode for Carrying Out the Invention

[0012] The following description details preferred embodiments of the present invention, but the present invention can be other embodiments and can be implemented in various ways. Therefore, in the application of the present invention, it is understood that it is not limited to the detailed examples of the arrangement of components and method procedures shown in the attached drawings.

[0013] Figure 1 is a front perspective view of a pet water-washing toilet 10 according to an exemplary embodiment of the present disclosure. The pet water-washing toilet 10 has a bowl 11, and the bowl 11 has a bottom 12, a right side portion 13A, a left side portion 13B, a front end portion 13C, and a rear end portion 13D. The front end portion 13C of the bowl 11 has an inlet opening 14 for a pet (e.g., a dog) to enter the bowl 11. The bowl 11 is placed on a base 15. A water storage tank or cistern 16 is placed at the rear end portion 13D of the bowl 11. The water storage tank 16 has a top cover 17. The water storage tank 16 is held by a support stand 23. A motion sensor 18 is attached to the support stand 23. One end of a water outlet hose 19 is attached to the left side portion 13B of the bowl 11 and extends into a water outlet opening 20 within a central region of the left side portion 13B. The water outlet hose 19 may also be attached to the right side portion 13A. A discharge opening 21 is at the rear end portion 13D of the bowl 11 and near the bottom 12 of the bowl 11. The discharge opening 21 is connected to a suction and excrement discharge pipe 22.

[0014] Figure 2 is a left side perspective view of the pet water-washing toilet 10. Figure 2 further shows a suction pump 24 and a water supply pump 25. An inlet hose 26 is attached to the inlet of the water supply pump 25. The water outlet hose 19 is attached to the outlet of the water supply pump 25 and extends to the water outlet opening 20 in the left side portion 13B of the bowl 11. A water supply hose 29 connected to a faucet supplies water to the pet water-washing toilet 10. An electrical control module 30 is attached to the support stand 23. Electric power is supplied to the electrical control module 30 through a power cord 31. The electrical control module 30 includes a timer, a switch, and a circuit that operates the motion sensor 18, the suction pump 24, and the water supply pump 25 in a manner well known in the art. Electrical wiring 33 connects the suction pump 24 and the water supply pump 25 to the electrical control module 30.

[0015] Figure 3 is a rear perspective view of the pet water-washing toilet 10. Figure 3 further shows the outlet pipe 28 of the suction pump 24. The suction discharge pipe 22 is connected to the suction outlet pipe 28. Figure 3 also shows the water outlet valve 34 in the water storage tank 16, the water storage tank inlet hose 35 extending from the water supply hose 29 into the water storage tank 16, and the inlet hose 26 for the water supply pump 25 extending from the water storage tank 16 to the water supply pump 25. When water is supplied from the water storage tank 16 to the water supply pump 25 through the inlet hose 26, the water outlet valve 34 opens so that the water storage tank 16 is refilled by the water supply hose 29. However, the water supply hose 29 may, in some cases, bypass the water storage tank 16 and be directly attached to the inlet of the water supply pump 25. Figure 4 is an enlarged rear perspective view of the suction pump 24 and the water supply pump 25 of the pet water-washing toilet 10.

[0016] During use, the pet water-washing toilet monitors the movement within the bowl area by a motion detector. When the pet enters the bowl, the pet is detected by the motion detector. When the pet has completed its excretion and exits the bowl, the movement of the pet is detected again. Then, after a selected time, for example, 5 to 10 seconds later, for a selected time, for example, between 5 and 30 seconds, the water supply pump and the suction pump operate by the electronics within the electric control module. The water supply pump supplies water to the water outlet hose at a desired pressure, and when the water enters the bowl, the water spreads over the entire bottom of the bowl. The suction pump immediately sucks water from the bottom of the bowl through the suction opening and washes it through the suction excretion outlet pipe. This combined operation of the water supply pump and the suction pump produces an improved cleaning effect on the bottom of the bowl. The suction excretion pipe can be directed outdoors, to a toilet, to a sewer pipe, or to a sealed container. When these pumps are stopped by the electronics, the electronics reset for the next water-washing cycle.
