Abstract

The presently disclosed subject matter is directed to an apparatus for the preparation of a cleaning, sanitizing, or sterilizing solution. In some embodiments, the apparatus comprises a modular component, such as a cartridge. The cartridge may contain chemical precursors to allow the generation of chlorine dioxide. The apparatus has a fluid inlet, and separates the fluid into a first flow path, which fills a reservoir. It also has a second flow path, which is heated before passing through the cartridge to create the desired gas. The fluid output from the cartridge is then fed into the reservoir.

Claims (43)

1. An apparatus for the preparation of a cleaning, sanitizing, or sterilizing solution, comprising:

a reservoir to hold said solution;

a first fluid path to allow incoming fluid to flow into said reservoir;

a reaction chamber, comprising chemical precursors adapted to react with incoming fluid;

a second fluid path to allow incoming fluid to flow to said reaction chamber;

a third fluid path from said reaction chamber to said reservoir;

a controller;

and a valve,

wherein said controller actuates said valve to enable said incoming fluid to flow into said first fluid path and said second fluid path.

2. The apparatus of claim 1 , further comprising a heating element in said second fluid path, such that heated fluid enters said reaction chamber.

3. The apparatus of claim 2 , wherein the temperature of said heated fluid is selected to control the reaction of the reactants at a desired rate.

4. The apparatus of claim 1 , wherein said reaction chamber comprises a replaceable cartridge.

5. The apparatus of claim 1 , wherein said precursors are selected from the group comprising sodium chlorite, citric acid, and combinations thereof.

6. The apparatus of claim 1 , wherein said first fluid path and said second fluid paths comprise conduits, and said conduits are dimensioned to allow a predetermined fraction of said incoming fluid to enter said second fluid path.

7. The apparatus of claim 1 , further comprising a pressure regulator to control the flow rate of said incoming fluid.

8. The apparatus of claim 7 , wherein said first fluid path and said second fluid path comprise conduits, and said conduits are dimensioned to allow a predetermined flow rate in said second fluid path.

9. An apparatus for the preparation of a cleaning, sanitizing, or sterilizing solution, comprising:

a reservoir to hold said solution;

a first fluid path to allow incoming fluid to flow into said reservoir;

a reaction chamber, comprising a replaceable cartridge and chemical precursors adapted to react with incoming fluid;

a second fluid path to allow incoming fluid to flow to said reaction chamber; and

a third fluid path from said reaction chamber to said reservoir;

wherein said second fluid path terminates in a water inlet, and said third flow path begins with a water outlet, further comprising an actuator, wherein said actuator actuates said water inlet and water outlet to a first position to create a fluid path between said water inlet and said water outlet though said cartridge.

10. The apparatus of claim 9 , wherein said actuator actuates said water inlet and water outlet to a second position to disrupt said fluid path between said water inlet and said water outlet though said cartridge so that said cartridge can be removed.

11. The apparatus of claim 9 , further comprising a heating element in said second fluid path, such that heated fluid enters said reaction chamber.

12. The apparatus of claim 11 , wherein the temperature of said heated fluid is selected to control the reaction of the reactants at a desired rate.

13. The apparatus of claim 9 , wherein said precursors are selected from the group comprising sodium chlorite, citric acid, and combinations thereof.

14. An apparatus for the preparation of a cleaning, sanitizing, or sterilizing solution, comprising:

a reservoir to hold said solution;

a first fluid path to allow incoming fluid to flow into said reservoir;

a reaction chamber, comprising chemical precursors adapted to react with incoming fluid;

a second fluid path to allow incoming fluid to flow to said reaction chamber;

a third fluid path from said reaction chamber to said reservoir;

a controller;

a first valve; and

a second valve,

such that said controller actuates first valve to enable the incoming fluid to flow into said first fluid path and actuates said second valve to enable the incoming fluid to flow into said second fluid path.

15. The apparatus of claim 14 , wherein said controller actuates said second valve after actuating said first valve, such that said reservoir is at least partially filled prior to opening of said second valve.

16. The apparatus of claim 14 , wherein said reaction chamber comprises a replaceable cartridge.

17. The apparatus of claim 14 , wherein said precursors are selected from the group comprising sodium chlorite, citric acid, and combinations thereof.

18. The apparatus of claim 16 , wherein said controller actuates said first valve and said second valve based on the type of replaceable cartridge installed in said apparatus.

19. The apparatus of claim 18 , further comprising a heating element in said second fluid path, such that heated fluid enters said reaction chamber and wherein said controller controls said heating element to set the temperature of said heated fluid entering said reaction chamber.

20. The apparatus of claim 19 , wherein said controller sets the temperature of said heater based on the type of replaceable cartridge installed in said apparatus.
