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.

First claim

What is claimed is:

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.
