System and method for generating and dispensing electrolyzed solutions


A system and method for generating and dispensing a diluted electrolyzed solution, where the system includes a solution generator, one or more containers, and one or more dispensing stations separate from the solution generator. The solution generator generates and dispenses a concentrated electrolyzed solution to the container(s). The dispensing station(s) draw the concentrated electrolyzed solution from the container(s), dilutes the drawn concentrated electrolyzed solution, and dispenses the diluted electrolyzed solution.
Related Terms: Concentrated Dilute

CROSS-REFERENCE TO RELATED APPLICATION(S)

The present application claims priority to U.S. Provisional Application No. 61/666,375, entitled “SYSTEM AND METHOD FOR GENERATING AND DISPENSING ELECTROLYZED SOLUTIONS”, filed on Jun. 29, 2012.

BACKGROUND

The present disclosure relates cleaning and sanitizing systems, and in particular, to cleaning and sanitizing systems for generating and dispensing cleaning solutions (e.g., alkaline cleaning solutions) and/or sanitizing solutions (e.g., acidic sanitizing solutions) with electrolysis reactions.

Electrolysis cells are used in a variety of different applications for changing one or more characteristics of a fluid. For example, electrolysis cells have been used in cleaning/sanitizing applications, medical industries, and semiconductor manufacturing processes. Electrolysis cells have also been used in a variety of other applications and have had different configurations. For cleaning/sanitizing applications, electrolysis cells are used to create anolyte liquids and catholyte liquid. Anolyte liquids have known sanitizing properties, and catholyte liquids have known cleaning properties.

SUMMARY

An aspect of the present disclosure is directed to a system for generating and dispensing a diluted electrolyzed solution (e.g., a diluted alkaline cleaning solution and/or a diluted acidic sanitizing/disinfecting solution). The system includes a solution generator configured to electrochemically generate and dispense an electrolyzed solution, and a dispensing station separate from the solution generator, and configured to dilute the electrolyzed solution, and to dispense the diluted electrolyzed solution. The system also includes a container configured to engage with the solution generator to receive the dispensed electrolyzed solution, to transport between the solution generator and the dispensing station, and to engage with the dispensing station to drawn the electrolyzed solution from the container to the dispensing station.

Another aspect of the present disclosure is directed to a system for generating and dispensing a cleaning solution, where the system includes a solution generator, one or more containers, and one or more dispensing stations separate from the solution generator. The solution generator includes an electrolysis cell configured to generate an alkaline solution, and one or more fill dispensers configured to dispense the alkaline solution. Each of the one or more containers includes a container housing and an access port through the container housing that is configured to receive the concentrated alkaline solution from one of the fill dispensers when the access port of the container is engaged with the one fill dispenser. At least one of the dispensing stations includes a water line configured to receive water, and a fluid line configured to engage the access port of one of the containers when the one container is engaged with the fluid line to draw the alkaline solution from the one container. The at least one dispensing station also includes a mixing region at which the received water and the drawn alkaline solution are configured to mix to provide a diluted alkaline solution, and a primary dispenser configured to dispense the diluted alkaline solution as the cleaning solution.

Another aspect of the present disclosure is directed to a method for generating and dispensing a diluted electrolyzed solution. The method includes electrochemically generating an electrolyzed solution in a solution generator, dispensing a regulated amount of the generated electrolyzed solution from the solution generator to a container that is removable from the solution generator, and moving the container having the electrolyzed solution to a dispensing station. The method also includes drawing the electrolyzed solution from the container to the dispensing station, diluting the drawn electrolyzed solution at the dispensing station, and dispensing the diluted electrolyzed solution from the dispensing station.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1A is a schematic illustration of a first conventional system for generating and dispensing an alkaline cleaning solution.

FIG. 1B is a schematic illustration of a second conventional system for generating and dispensing an alkaline cleaning solution.

FIGS. 2A-2C are perspective illustrations of a system of the present disclosure for generating, transporting, and diluting a concentrated electrolyzed solution, and for dispensing the diluted electrolyzed solution.

FIG. 3 is a schematic illustration of an example solution generator of the system of the present disclosure.

FIG. 4 is a schematic illustration of an example dispensing station of the system of the present disclosure.

DETAILED DESCRIPTION

The present disclosure is directed to a system that includes a solution generator, one or more transportable containers, and one or more remote dispensing stations, which provide a convenient assembly for generating, transporting, and dispensing electrolyzed solutions, such as alkaline cleaning solutions and acidic sanitizing/disinfecting solutions, for example. Mobile cleaning units, such as mobile floor cleaners, conventionally use alkaline cleaning solutions and/or detergents for cleaning surfaces, such as floors. For cleaning units that rely on alkaline cleaning solutions, the cleaning units can be filled with the alkaline solutions from stationary solution generators, or the alkaline solutions can be generated onboard the cleaning units themselves.

Cleaning units having onboard generators (e.g., as disclosed in Field et al., U.S. Pat. No. 8,156,608) may generate the alkaline solutions in an on-demand manner and/or may generate and store the alkaline solutions in internal reservoirs. These cleaning units are convenient in that the alkaline solutions may be generated and transported along with the respective cleaning units. However, such cleaning units have higher power consumptions, are typically more expensive, and generally do not allow interchangeable use of the alkaline solutions between different units.

Cleaning units that are filled from stationary solution generators (e.g., as disclosed in Guastella et al., U.S. patent application Ser. No. 13/410,535) are typically less expensive, and allow multiple cleaning units may be filled from a single stationary solution generator. However, stationary solution generators require the cleaning units to move back-and-forth between the stationary solution generators (for refilling) and the areas to be cleaned. For example, as shown in FIG. 1A, a user is typically required to move mobile floor cleaner 10 back-and-forth between solution generator 12 (for refilling) and the remote locations to be cleaned. As can be appreciated, for large buildings, this can increase the time required to perform the cleaning operations with mobile floor cleaner 10.

Alternatively, as shown in FIG. 1B, a user could fill transport vessel 14, and move transport container 14 back-and-forth between mobile floor cleaner 10 and solution generator 12. In this situation, the user may fill transport vessel 14 with the alkaline solution from solution generator 12, and then carry, push, or otherwise move transport container 14 to mobile floor cleaner 10. As such, mobile floor cleaner 10 itself is not required to be moved back to solution generator 12 for refilling. Rather, the user may fill mobile floor cleaner 10 from transport vessel 14. However, in order to provide a suitable volume of the alkaline solution to mobile floor cleaner 10, transport vessel 14 itself will typically be large and cumbersome, which also can also increase the time required to perform the cleaning operations with mobile floor cleaner 10.
