The solution plate 10 comprises a lid to the solution tank or tanks 4, 6. A fluid is passed through the solution plate 10 into the solution system. A strainer 12, a pump 13, and at least one solenoid valve 15 for controlling a fluid flow within the delivery line 5 are provided. The provision of, and the specific location of such elements, is provided to illustrate an exemplary embodiment of the present disclosure. It will be recognized that the invention(s) provided herewith are not limited to the specific arrangement of or provision of certain parts in FIG. 1. For example, the pump 13 may be provided at any one or more locations within the system 2. Additionally, the pump 13 may comprise various different types of pumps including, for example, peristaltic pumps, lobe pumps, centrifugal pumps, vane pumps, gear pumps, diaphragm pumps, and other pumps as will be recognized by one of ordinary skill in the art.
[0036] Although FIG. 1 depicts a device comprising a first solution tank 4 and a second solution tank 6, alternative embodiments of the present disclosure contemplate providing a single storage or solution tank. In such embodiments, a first solution is provided in and dispensed from the single solution tank until substantially all of the first solution is spent or emptied from the tank. Subsequently, a second fluid is supplied to the single solution tank, and a system flush is provided through the dispensation of the second fluid from the solution tank. It will also be recognized that more than two fluids may be supplied within a solution tank, regardless of the number of solution tanks that are provided within systems and devices of the present disclosure.
[0037] As shown in FIG. 1, the strainer 12 is provided in the delivery line and is adapted to filter and remove debris from a fluid in the delivery line 5. In various embodiments, the strainer 12 is selectively applied or inserted into the system, and it is contemplated that the system may run with or without the strainer 12. Also, the strainer may be placed at many various spots along the fluid lines.
[0038] The system 2 of FIG. 1 comprises a shared or common delivery line 5 for chemicals and solutions provided in both the first solution tank 4 and the second solution tank 6. In various embodiments, methods of operating the system are provided, as would be understood by skilled artisans. In some preferred embodiments, the method comprises dispensing a fluid from the first solution tank 4 through at least a portion of the delivery line 5. The dispensation of the fluid from the first solution tank 4 is terminated, and a second flow is provided, wherein the second flow comprises a flow of a second fluid or chemical from the second solution tank 6 through at least portions of the delivery line 5, where the first solution was provided or directed.
[0039] In various embodiments, a cleaning device is provided wherein a first and second fluid are provided in first and second solution storage tanks. In certain embodiments, the first and second fluids are directed through a common fluid delivery path and wherein the device is devoid of other fluid flow paths such that the fluids must each flow through said fluid delivery path. In alternative embodiments, at least one of a first and second fluid is in fluid communication with a plurality of fluid delivery paths, and wherein a user may select a desired path. In such embodiments, a user is provided with the ability to selectively direct a second fluid through the same delivery flow path that a first fluid was previously routed. The user is also provided with an ability to bypass the first delivery path and direct the second fluid to a separate conduit or delivery path when a flushing or sharing of a single flow path is not desired. The selection of a fluid delivery path by a user is preferably accomplished by a user input. The user input may comprise, for example, activation of a switch on a control panel, an electronic input, and various other input as will be recognized by one of ordinary skill in the art. Such embodiments may be desirable, for example, when a user wishes to have the option to flush a first delivery path with a second fluid, but also occasionally wishes to dispense the second fluid through a line or path that is dedicated to the second fluid and wherein no cross-contamination occurs during dispensation.
[0040] As shown in FIG. 1, a majority of the delivery line 5 comprises a shared delivery line. A portion of the system (indicated as 20 in FIG. 1) comprises a dedicated path for only a second fluid (e.g. an extraction fluid). As shown in FIG. 1, a first fluid is operable to travel through the delivery system and delivery line 5 and be dispensed through a first outlet 18. A second fluid is operable to be transmitted through the delivery line 5 and may be ejected through any one or more of first 18, second 14 and third outlets 16. In various embodiments, the outlets 14, 16, 18 comprise and/or are provided with nozzles for pressurized, directed ejection of the fluid. Flow of the fluids to the outlets 14, 16, 18 is preferably controlled by the solenoid valve 15. For example, during a cleaning operation wherein a first fluid is to be dispensed from the delivery line 5, a first solenoid valve 15a is provided in a closed position and a second solenoid valve 15b is provided in an open position and the fluid is thus directed out through the first outlet 18. To rinse or purge the first fluid from the delivery line 5, a second fluid (preferably comprising a solvent or solvency properties) is directed through the same path as the first fluid. In various embodiments, flow may be directed or redirected through the second and third outlets 14, 16 by altering the state or positions of the solenoid valves 15a, 15b. Additional solenoid valves 15c, 15d are provided proximal to the first and second 4, 6 solution tanks to selectively enable flow of a fluid from the tanks.
[0041] In preferred embodiments, the operation of the solenoid valves 15 shown in FIG. 1 is controlled through logic built into the system. In alternative embodiments, the flow of at least a first and a second fluid through the system 2 is controlled by direct inputs by a user (e.g. switches and prompts). Preferably, a cleaning operation is initiated and the flow of a first and second fluid is automatically controlled by timing mechanisms and signals to the solenoid valves 15 to provide the appropriate timing and flow rate(s) of a first fluid and a second fluid and wherein the second fluid is dispensed in a manner that is suitable to purge or clean the first fluid from at least a portion of the delivery line 5.
