The cleaning dispensing machine is compatible with product cleaner containers of different dimensions and of different types of cleaners.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to cleaning product dispensing system and, more particularly, to a cleaning product dispensing system that is portable and cab ene readily installed in any dwelling to allow users to refill their existing claning product reservoirs.
2. Description of the Related Art
Several designs for dispensing systems have been designed in the past. None of them, however, include an easily transportable dispensing system capable of refilling many different products while wirelessly monitoring the supply levels of each product.
Applicant believes that a related reference corresponds to U.S. patent publication No. US 2010/0072273 issued to Brown for a method and apparatus for vending a containerized liquid product utilizing an automatic self-service refill system. The Brown reference also provides a method of vending fluid product to a customer utilizing an original container. However, it differs from the present invention because the Brown reference requires the reading of a bar code on the container to be refilled so that the apparatus can determine which product to dispense.
Also, the Brown reference requires the mixing of two fluids such as water and concentrate so that the final product can be delivered to the user. This mixing process is cumbersome and can lead to a poor quality delivered product. Also, the Brown reference will not work with any container the user has available. The user must use the container having the bar code of the product he wants refilled. In addition, the bar code has to be in good condition so that the apparatus can read it. The present invention allows the user the flexibility to refill any container with the product of his choosing.
Notably, the Brown reference does not motivate one of ordinary skill in the art to include the float sensor assemblies found in the present invention that are connected to wireless communication to notify a remote computer of the unit's supply levels. Moreover, the Brown reference does not teach of dispensing the product using a control unit that dispenses the product based on serving and viscosity. In addition, the Brown reference does not teach of transportation means such as the slots found in the base of the present invention to readily move the device between locations. Also, the Brown reference does not motivate one of ordinary skill in the art to use a one way valve, or a check valve, that keeps the hoses primed at all times.
Other documents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.
SUMMARY OF THE INVENTION
It is one of the main objects of the present invention to provide a dispensing system to be used to refill cleaning product containers, thereby reducing the need for plastic containers and its associated pollution.
It is another object of this invention to provide a dispensing system that allows users to refill their cleaning product containers at a convenient location such as in their apartment building.
It is still another object of the present invention to provide a dispensing system using wireless communication to notify the management when the amount of product in the machine is low. This makes maintaining the machines more efficient than having to visually inspect machines that may not need refilling or risk having a machine go empty which leads to lost profits.
It is another object of the present invention to provide a machine with effective drainage to prevent spillage and maintain the machine in a cleaner condition.
It is still another object of the present invention to provide such a dispensing machine that is compatible with cleaning product containers of different dimensions and of different types of cleaners, including detergent, soaps, cleaners, etc.
It is another object of the present invention to provide a dispensing machine having slots at its base to facilitate the transportation of the machine between locations.
It is another object of the present invention to provide a payment assembly that allows users to effectuate transactions with a plurality of negotiable instruments.
It is yet another object of this invention to provide such a dispensing system that is inexpensive to implement and maintain while retaining its effectiveness.
Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION
Referring now to the drawings, where the present invention is generally referred to with numeral 10, it can be observed that it basically includes dispensing machine 20 being a box-like structure, in a preferred embodiment, as shown in FIG. 1. Dispensing machine 20 further includes dispensing compartments 22 of a predetermined dimension to cooperate with cleaning containers C to be refilled. As seen in FIGS. 2 and 2C, dispensing compartments 22 include drainage holes 22a; 22b that allow for the drainage of spilled liquids in dispensing compartments 22.
As shown in FIG. 2B, dispensing compartments 22 further include nozzles 24 positioned at a preselected location to effectively dispense liquids into cleaning containers C being refilled. As shown in FIGS. 1 and 3, dispensing machine 20 includes transportation slots 26 used to readily transport the machine. In a preferred embodiment, a forklift can be journaled into transportation slots 26, which serve as a means for lifting and transporting dispensing machine 20.
Dispensing machine 20 further includes dispensing machine door 28 having payment assembly 40 mounted thereon to receive payments from a plurality of tangible financial instruments, such as cash, credit, or debit cards, as seen in FIGS. 1, 3, and 3A. As seen in FIGS. 1 and 3A, payment assembly 40 includes payment receiver 42 to accept such payments.
As shown in FIGS. 3 and 4, the interior space of dispensing machine 20 includes float sensor assembly 60 that includes float sensor rods 62 having float sensors 64 to monitor the liquid remaining in supply containers 122 of supply reservoir assembly 120. In addition to float sensor rods 62, supply containers 122 also receive supply hoses 124 that transport the liquid from supply containers 122 to containers C in dispensing compartments 22. Supply hoses 124 are inserted into stabilizing rigid sleeves 126 which provide a predetermined and effective amount of stability to provide efficient flow of the liquid through supply hoses 124.
As seen in FIG. 3A, drainage assembly 100 includes drainage tank 102 where spilled liquids in dispensing compartments 22 are stored as those liquids drain through drainage holes 22a and 22b using drainage hoses 104. As shown in FIG. 6B, fluid distribution assembly 80 includes three-way valve 82, which is fed by supply hoses 124. Three-way valve 82 coordinates the liquid that will be dispensed by nozzle 24 from the plurality of supply hoses 124. Fluid distribution assembly 80 can include, as seen in FIGS. 6A and 6B backflow preventer 84 to prevent liquid not sent through nozzle 24 from traveling backwards in the direction of supply reservoirs 122. In a preferred embodiment, supply hoses 124 remain primed at all times to increase the effectiveness and fluid delivery speed of the present invention.
As seen in FIG. 9, control assembly 140 includes motherboard 142, switches 144, and wireless communication means 146. Control assembly 40 is used to coordinate which liquid will be dispensed based on a user's selection. Wireless communication means 146 can communicate with a remote computerized station using a global computer network to inform an administering user of the supply levels remaining in supply containers 122.
Pump assembly 160 includes pumps 162; 162a as shown in FIG. 10. Pumps 162; 162a are used to push and keep primed liquids through supply hoses 124 from supply containers 122 until the liquids are dispensed through nozzle 24.
The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
