Abstract

A method, apparatus, and system for obtaining a solution from a solid product are disclosed. A solid product is housed in a dispenser. A liquid is introduced into the housing of the dispenser to interact with the solid product to form a solution. To control the concentration of the formed solution, the turbulence of the liquid introduced to the dispenser is controlled and adjusted either manually or on a real time basis to account for varying characteristics of either or both of the solid product and the liquid. The dispenser will adjust the turbulence based on the characteristics to maintain a formed solution within an acceptable range of concentration. The concentrated solution can then be discharged from the dispenser to an end use application.

First claim

What is claimed is:

1. A method for obtaining a solution from a solid product and a liquid, comprising:
combining the liquid and solid in a pool to form the solution, the liquid being added to the pool with a variable turbulence; and
adjusting the turbulence of the liquid being added to the pool based upon a characteristic of the turbulence or solid product to maintain a desired concentration of the solution that is discharged from the dispenser and towards an end use application;
wherein the pool configured to erode the solid product to form the solution.

2. The method of claim 1 , further comprising continuously preparing a new solution of new liquid and solid product being formed with the adjusted liquid turbulence to obtain the desired concentration.

3. The method of claim 2 , further comprising discharging the solution from the dispenser towards an end use application without the solution returning to the dispenser.

4. The method of claim 1 , wherein the step of adjusting the liquid turbulence comprises changing the flow rate of the liquid contacting the solid product.

5. The method of claim 1 , wherein the step of adjusting the liquid turbulence comprises changing the distance between a source of the liquid and the solid product.

6. The method of claim 1 , further comprising adding the liquid to the solution to further combine the liquid and the solid product.

7. The method of claim 1 , wherein the characteristic comprises:
a. the temperature of the liquid;
b. the chemistry of the solid product;
c. the density of the solid product;
d. the shape of the solid product; or
e. the climate of the location of the solid product or dispenser.

8. The method of claim 1 , further comprising discharging the solution to a sump.

9. The method of claim 8 , further comprising adding additional liquid to the solution as it is dispensed from the sump and towards the end use application.

10. The method of claim 1 , further comprising dispensing the solution to an aspirator for use in filling a container.

11. A method of controlling the concentration of a solution of a solid product and a liquid dispensed from a dispenser, comprising:
combining the liquid and solid product in a pool to form the solution, the liquid being added to the pool with a variable turbulence;
measuring the concentration of the solution; and
adjusting the turbulence of the liquid being added to the pool based upon the measured concentration of the solution to provide a desired concentration of the solution that is discharged towards an end use application.

12. The method of claim 11 , further comprising repeating the steps of contacting, measuring, and adjusting until a desired concentration of solution is obtained.

13. The method of claim 12 , further comprising dispensing the desired concentration of solution from an outlet of the dispenser towards the end use application without the solution returning to the dispenser.

14. The method of claim 11 , wherein the adjusting step is performed in a housing containing the solid product.

15. The method of claim 11 , wherein the adjusting step occurs after an initial amount of solution has been dispensed and prior to the end use application.

16. The method of claim 11 , wherein the adjusting step comprises adjusting the liquid turbulence comprises changing the flow rate of the liquid contacting the solid product or changing the distance between a source of the liquid and the solid product.

17. A dispenser configured to obtain a solution from a solid product and a liquid, comprising:
a housing;
a cavity within the housing for holding a solid product;
a liquid source adjacent the cavity for providing a pool of liquid to contact the solid product to create a solution;
wherein the liquid source comprises a variable liquid turbulence control to control the turbulence of the liquid being added to the pool and contacting the solid product based upon a characteristic of the liquid, environment climate, or solid product; and
an outlet adjacent the cavity for discharging the solution from the dispenser and towards an end use application without having the solution return.

18. The dispenser of claim 17 , further comprising a diffuse manifold positioned between the liquid source and the cavity.

19. The dispenser of claim 18 , further comprising a collection zone for the solution between the cavity and outlet.

20. The dispenser of claim 19 , further comprising a probe in the collection zone for determining the concentration of the formed solution.
