Abstract

An ultrasonic wave washing unit may include a housing including a media inlet, a media outlet, and a bottom surface; a plurality of ultrasonic transducers disposed about and extending from the bottom surface; a support structure including a chair and sleeve, wherein the support structure is coaxially disposed within the housing within the plurality of ultrasonic transducers; wherein the chair is operable to hold an air filter and receive residue from the air filter when washed within the ultrasonic wave washing unit; and the sleeve is operable to engage with the air filter and secure the air filter within the chair.

Claims

1. An ultrasonic wave washing unit comprising:

a power source;

a housing comprising a media inlet, a media outlet, and a bottom surface;

a plurality of ultrasonic transducers coupled to the power source and disposed about and extending from the bottom surface within the housing; and

a support structure comprising a chair, wherein the support structure is disposed within the housing within the plurality of ultrasonic transducers;

wherein the chair is operable to hold an air filter and receive residue from the air filter when the air filter washed within the ultrasonic wave washing unit.

2. The ultrasonic wave washing unit of claim 1, wherein the chair comprises supports and defines apertures through which the received residue may flow.

3. The ultrasonic wave washing unit of claim 2, wherein the chair comprises four supports and defines four apertures.

4. The ultrasonic wave washing unit of claim 1, wherein the chair comprises stainless steel.

5. The ultrasonic wave washing unit of claim 1, wherein the support structure is coaxially disposed within the housing.

6. The ultrasonic wave washing unit of claim 1, wherein the media inlet and the media outlet are the same element.

7. The ultrasonic wave washing unit of claim 1, wherein the plurality of ultrasonic transducers emit ultrasonic energy with a distinct amplitude, frequency, power and/or duration.

8. The ultrasonic wave washing unit of claim 1, wherein the ultrasonic transducers are evenly spaced within the housing.

9. The ultrasonic wave washing unit of claim 1, wherein the support structure further comprises a sleeve operable to engage with the air filter and secure the air filter within the chair.

10. The ultrasonic wave washing unit of claim 1, wherein the media outlet is disposed below the support structure.

11. An ultrasonic cleaning system comprising:

a media source;

a power source;

an ultrasonic wave washing unit, wherein the ultrasonic wave washing unit comprises;

a housing comprising a media inlet in communication with the media source, a media outlet, and a bottom surface;

a plurality of ultrasonic transducers coupled to the power source and disposed about and extending from the bottom surface within the housing; and

a support structure comprising a chair and a sleeve, wherein the support structure is coaxially disposed within the housing within the plurality of ultrasonic transducers;

wherein the chair is operable to hold an air filter and receive residue from the air filter when washed within the ultrasonic wave washing unit; and

wherein the sleeve is operable to engage with the air filter and secure the air filter within the chair.

12. The ultrasonic cleaning system of claim 11, further comprising a transducer control unit.

13. The ultrasonic cleaning system of claim 12, wherein the transducer control unit is coupled to the power source.

14. The ultrasonic cleaning system of claim 11, wherein the media outlet is in communication with the media source.

15. A method for cleaning an air filter, comprising:

providing an ultrasonic wave washing unit comprising a chair;

placing an air filter in the ultrasonic wave washing unit;

applying ultrasonic energy to the air filter from the ultrasonic wave washing unit to remove residue from the air filter;

collecting the residue within the chair; and

removing the air filter from the ultrasonic wave washing unit.

16. The method of claim 15, further comprising the step of filling the ultrasonic wave washing unit with media.

17. The method of claim 16, wherein the ultrasonic wave washing unit is filled with media before the air filter is placed in the ultrasonic wave washing unit.

18. The method of claim 16, wherein the ultrasonic wave washing unit is filled with media after the air filter is placed in the ultrasonic wave washing unit.

19. The method of claim 16, further comprising adding detergent to the media after a time delay.

20. The method of claim 16, wherein the media is held at a controlled temperature.
