The present invention relates generally to the field of pet water dispensers, and more particularly to a refrigerated pet water dispensing and bowl cleaning system that provides cold water for pets at all times while keeping the bowl clean from hair and debris.
RELATED ART
Presently pet water dispensers provide fresh, cool water for only a short time after they are filed especially in hot sunny climates or the water freezes in cold icy climates. Furthermore, without constant attendance by the pet owner, present day pet water dispensers quickly accumulate pet hair, saliva and food particles that introduce bacteria into the water and contaminate the dispenser making the water unhealthy for the pet. Thus, there is a need for an automatic pet water dispenser that requires only occasional maintenance and refilling. More specifically, there is a need for an automatic pet water dispenser that once filed with fresh water automatically dispenses water into the bowl; automatically circulates fresh water through the cooling/heating system; automatically drains the bowl of water twice a day; automatically filters hair and debris through a screen that is removable to be cleaned manually; automatically pumps and sprays pressurized water against the bowl to clean any remaining residue in the bowl; automatically filters the water/residue through a filtration system; automatically regenerates the left-over water through a second filter; automatically re-circulates the filtered water with the fresh water; and automatically pumps cool fresh water back into the bowl. Furthermore, there is a need for an automatic pet water dispenser that slowly circulates the water 24 hours per day through a refrigeration unit to keep it at a constant cold temperature which is adjustable by a digital thermostat on a control panel.

DETAILED DESCRIPTION OF AN EXEMPLARY EMBODIMENT OF THE PRESENT INVENTION
While specific exemplary examples and embodiments are discussed below, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations can be used without parting from the spirit and scope of the invention. In fact, after reading the following description, it will become apparent to a person skilled in the relevant art how to implement the invention in alternative examples, environments and embodiments.
In one embodiment, the invention is a refrigerated pet water dispensing and bowl cleaning system that provides cold water for pets at all times while keeping the bowl clean from hair and debris and the overall invention 10 is comprised of the water tank 12 which has a removable cover 48 through which fresh water is added to and thus introduced into the overall invention. The water tank 12 sits on top of the housing assembly 14 and can be unitary with the body of the housing assembly or insertably removable with the body of the housing assembly. Connected to the housing assembly 14 is the water bowl 16. Water fills the water bowl 16 via the water fall 18 and drains back into the system via the drain 22. The overall invention is controlled, run and monitored via the digital display/controller 20. The housing assembly 14 contains a series of water pumps 32 and a filter box 38 that cleans the water of hair and debris. The filter box 38 has a removable filter clean-out 40. The housing assembly also contains a shortwave ultra violet light 34 that kills bacteria and a thermoelectric cooling plate 36 to regulate the temperature of the water. The water bowl 16 houses the motor 30 which controls the drain disc 24. The drain disc 24 has two drain holes 26. As the water needs to be drained from the water bowl 16, the motor 30 activates the drain disc 24 rotating the drain hole 26 into alignment with the drain 22. Once the water bowl 16 is drained, the motor 30 rotates the drain disc 24 until the drain hole 26 is no longer aligned with the drain 22. The drain disc prevents water from leaking into the drain via the drain seals 28. The water bowl 16 also has a temperature sensor 44 and an overflow drain 46. The water bowl 16 is kept clean of hair and debris via the bowl cleaning water jets 42. Using a standard 2.5 liter water bottle which is removably inserted into the overall invention 10 in place of the water tank 12 water goes into the bowl and allows the refrigeration unit to circulate fresh water through the cooling system automatically. Twice a day, at a time chosen by and programmed into the digital display/controller and the underlying integrated circuit 58 by the pet owner, the bowl of the water dispenser drains out and filters hair and debris through a screen that is removable to be cleaned manually. At the same time, another pump turns on and sprays pressurized water against the bowl to clean any remaining residue. That water/residue is also filtered through the filtration system. The left-over water is regenerated through a second filter and is circulated with fresh water and then pumped back into the bowl. The pumps slowly circulate the water 24 hours per day through the refrigeration unit to keep it at a constant cold temperature which is adjustable by a digital thermostat on the control panel which is located on the front of the unit or the inline water heater 62 heats the water to keep the water at the desired constant temperature when the surrounding ambient temperature is deemed too frigid. The overall invention is energized either by a DC charger 50 which is energized by an automobile cigarette lighter jack or a rechargeable battery 52 which is charged by way of a AC/DC converter 56 fed by a 100-250 V input. The water pumps, ultra violet light, thermoelectric cooling plate, cooling/heating plate, car/DC input, DC charger for car or DC input, rechargeable batter, AC input for 100-250 V, AC/DC converter, integrated circuit for the digital display/controller, speaker for music 54, motor, temperature sensor, in-line water heater 62 and the electrical system 66 are all communicatively connected with the integrated circuit 58 so that these various electrical components can be automatically controlled by the digital display/controller which has been programmed by the pet owner. The water conduit system 64 fluidly connects the water pumps, water tank, water bowl, drain, filter box, bowl-cleaning water jets, overflow drain and the in-line water heater to circulate the water inserted into the overall invention and presented to the pet in the water bowl.
FIG. 8 illustrates a detailed cross sectional schematic diagram view of an exemplary embodiment of a Refrigerated Pet Water Dispensing and Bowl Cleaning System provided in the disclosed embodiment. The respective components thereon are labeled as defined above.
