While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 illustrates one embodiment of a pet wash station 10 according to the invention. The pet wash station includes a wash room 12 and an equipment room 14. The wash room is configured for and provided with means for manually washing, rinsing and optionally air drying a pet. The equipment room 14 houses operational and support equipment, electrical wiring and controls, electric power, water supply and sewer connections, and anything to which restricted access is to be established. The wash room 12 and equipment room 14 are separated by a common wall 16.
The preferred wash room 12 and equipment room 14 are generally enclosures, each with a floor, a ceiling, surrounding sides, and a doorway, but are connected together to establish a self-contained vending unit that can be shipped as a single unit ready to be set into place and hooked up to site electrical power, water supply and sewer lines.
The wash room 12 is provided with a wash tub 18 to place a pet into for washing, wash-water supply facility to enable manual washing the pet in the tub, optional air drying supply facility, and a vending control unit 20 for controlling availability of the wash water and, if applicable, the drying air in the wash room. The wash tub 18 is positioned above the floor 30 of the wash room 12 so that the wash room floor 30 catches water that may splash from the tub 18.
In the embodiment illustrated in FIG. 1, a flexible liquid hose 22 extends from under the common wall 16 to supply a flow of liquid. The free end of the hose 22 is located above and proximate to the wash tub 18 for wash and rinse capability of a pet in the tub 18. The liquid hose 22, on a feed end, is connected to a pressurized wash-water supply unit 24 in the equipment room 14 (see FIG. 2). Further, a manually operable (e.g., trigger operated) spray head or nozzle 26 may be connected to the free end of the hose 22 for fine user flow control while washing the pet.
Turning to FIG. 2, the wash-water supply unit 24 may be, for example, a pump, connected to a water supply line to the pet wash station 10 (i.e., an external water source) to supply the user with clean water for both washing and rinsing the pet. The wash-water supply unit may alternately be configured to provide both a washing mixture (e.g., shampoo and water) and clean rinse water, such as an electrically controlled mixing manifold responsive to user selected input at the vending control unit 20.
The wash tub 18 includes a drain 28 connected to drain into a collection trough 32 in the floor of the equipment room 14. The wash room floor 30 slopes down towards and under the common wall 16 to the collection trough 32 such that water on the wash room floor 30 flows (by gravity) through a space 40 between the common wall and the floor 30 to also drain into the collection trough 32. The waste water in the collection trough 32 (from both the wash tub and the wash room floor) is pumped through a filter to remove the hair and then into the outside sewer line. As shown schematically, the trough 32, and particularly the drain associated therewith, is in fluid communication with a pumping system 38. The pumping system 38 is sufficiently sized to facilitate the drainage of waste water and refuse which has collected on the wash room floor 30 and/or the tub 18. Those skilled in the art will recognize that the aforementioned grading or sloping of the wash room floor 30 for drainage under gravity need not be incorporated, as the pumping system 38 operates to actively remove a majority of standing waste water, with the remainder being pushed into trough 32 via a squeegee, mop, or the like.
This wash room floor 30 drainage arrangement permits quick and easy floor cleanup with a broom or floor squeegee or spray hose, by simply sweeping, pushing or spraying any water and hair on the floor under the common wall 16 and into the collection trough 32. Thereafter, the pumping system 38 will efficiently pump the waste water through the sewer connection connected to the pet washing station 10.
As illustrated in FIG. 2, the wash room 12 has a wash tub 18 and floor 30 combination that provide two alternate pet wash locations. In particular, the wash room floor 30 is sufficiently larger than the tub 18 (when viewed from above) so that a pet owner has room to wash a pet on the floor 30 rather than in the tub 18. Configuring the wash room floor 30 as an alternate pet washing location is particularly useful for washing larger pets (that may be difficult for the user to lift into the tub) and pets that may resist staying in the tub 18. However, use of the wash room floor 30 as a pet washing location will result in increased pet hair accumulation on the floor 30 and normally aggravate cleanup of a conventional floor. Advantageously, this potential additional hair accumulation on the floor 30 of the wash room 12 will not significantly affect the speed and ease of cleaning of the wash room floor 30 of the pet wash station 10. The wash room floor 30 is graded such that liquid drains toward and under the common wall 16 via the space 40, thereby draining directly into the collection trough 32 in the equipment room 14. As such, the floor 30 is quickly and easily cleaned by simply sweeping or pushing or spraying the hair and waste water on the floor 30 under the common wall 16 into the collection trough 32 in the equipment room 14, as illustrated in FIG. 3.
Optional drying air may be provided through a flexible air hose 34 connected at one end to a blower or other pressurized air supply unit 36 in the equipment room 14. The other end of the hose 34 is available in the wash room 12 to supply pressurized air to dry the pet after washing.
FIG. 3 illustrates the vending control unit 20, which controls the availability of washing liquid and drying air responsive to user selected input. In particular, in an arrangement for self-service wash facilities, the vending control unit accepts a wash-cycle selection made by the user (e.g., by selection of option(s) with one or more control knobs, illustrated as control knobs 42, 44, 46 in FIG. 3), and responsive thereto, controls the wash-water and air supply units in the equipment room 14. Thus the control unit controls the supply availability and length of time of the washing and rinsing fluid to the spray nozzle 26, and the control of the air to the drying hose 32. The vending control unit accepts payment from the user in any convenient form (e.g., coins, paper, tokens, debit or credit cards, etc.) to activate its operational control functions. FIG. 3 shows a control unit 20 with a knob 42 for selecting air, water, and soap, and a knob 44 for altering the water temperature, and a knob 46 for altering the air temperature. Further, FIG. 3 shows a payment interface for accepting change, bills, credit/debit cards, and any other conventional forms of on-site payment processing.
Typically, the vending control unit 20 is located inside of the washroom 12. However, in alternative embodiments, the vending control unit 20 is located outside of the washroom 12. As such, access to the washroom 12 is restricted until the user pays a predetermined fee to use the pet wash station 10.
FIG. 4 illustrates an embodiment of the pet wash vending station 100 that includes two separate wash rooms 102, 104 connected to a single equipment room 106. The wash rooms 102 and 104 and equipment room 106 are generally enclosures, each with a floor, a ceiling, surrounding sides, and their own individual doorways, but are connected together to establish a self-contained vending unit 100 that can be shipped as a single unit ready to be set into place and hooked up to site electrical power, water supply and sewer lines. Further, each individual wash room 102 and 104 contains all of the amenities of the previously described wash room 12 (see FIG. 1). The primary difference is equipment room 106 is shared between wash rooms 102 and 104. As such, the equipment room 106 contains an adequate water pump and an adequate air pump to supply two wash rooms 102 and 104. Further, equipment room 106 includes a common drainage trough that receives waste water and refuse from each of the individual wash rooms 102, 104 through openings in the bottoms of their respective common walls formed with equipment room 106. This “common trough” may be a single centrally located trough, or multiple interconnected troughs that in either case are in fluid communication with pumping system 38. In the case of multiple interconnected troughs, such an embodiment includes a trough positioned proximate the opening of each common wall. These troughs are connected by one or more cross pipes. This interconnected system is in turn connected to pumping system 38, and as such, functionally forms a common trough that operates in the same or similar manner as collection trough 32 illustrated in FIG. 2.
