Abstract

An air treatment system having an improved control system. The control system may include a dynamic “dead front” display that varies the display based on mode of operation. The display may include capacitive touch sensors and include an array of capacitive film segments or traces integrated into the display. The control system may include a self-contained electronics module that can be tested and calibrated before installation in the ATS. A dust sensor assembly may be integrated into the electronics module. The front cover may be attached with a mechanical attachment at the top and a magnetic attachment on the bottom. The ATS may include a filter retainer assembly with a rotating clip configured to perform in a cam-like manner to firmly clamp the particulate filter and carbon filter in place.

Claims

1. An air treatment system comprising:

a system housing having a front and a rear, said front defining an inlet, said rear defining an outlet;

a plurality of filters arranged in said filter housing;

a blower for moving air through said plurality of filters;

a control system having a display and controlling operation of said blower;

a base affixed to a bottom of said system housing, said base having a plurality of fixed feet disposed toward said rear of said system housing and a roller disposed toward the front center of said filter housing; and

a handle disposed toward a top of said rear of said system housing, said handle including a central handle and a pair of side handles disposed on opposite sides of said central handle.

2. The air treatment system of claim 1 wherein said base include a bobbin for manually wrapping said power cord, said bobbin disposed toward said rear.

3. The air treatment system of claim 2 wherein said handle is of a molded, one-piece construction.

4. An air treatment system comprising:

a filter housing;

a filter fitted into said housing, said filter having a frame and a clip rotatably mounted to said frame, said clip being manually movable between an open position and a closed position, said clip configured to interact with said filter housing to draw said filter into said filter housing as said clip moves from said open position to said closed position and to secure said filter in said filter housing when in the closed position;

wherein said clip is disposed toward one end of said filter; and

wherein said filter includes a catch disposed toward an opposite end of said filter, said catch protruding from said frame and configured to engage with said filter housing, whereby said filter is secured in said filter housing fitting said catch into said filter housing and moving said clip from said open position to said closed position.

5. The air treatment system of claim 4 wherein said filter housing includes a locking protrusion and said clip includes a hook configured to engage said locking protrusion when in said closed position.

6. The air treatment system of claim 5 wherein said clip and said locking protrusion are configured such that said hook enters into initial engagement with said locking protrusion partially through movement between said open and closed positions and such that continued movement of said clip toward said closed position following said initial engagement draws said filter into said filter housing.

7. The air treatment system of claim 6 wherein said filter housing include a shoulder and said filter includes a face seal engaged with said shoulder, whereby drawing said filter into said filter housing compresses said face seal against said shoulder.

8. The air treatment system of claim 7 wherein said hook and said locking protrusion are configured such that said hook is required to deform about said clip as said clip is moved from said open position to said closed position, said deformation creating a snap-fit engagement resisting movement of said clip into and out of said closed position.

9. The air treatment system of claim 7 wherein said filter includes a locking pin disposed adjacent said clip, said clip including an outer surface configured to interfit with said locking pin when said clip is in said closed position creating a snap-fit engagement resisting movement of said clip into and out of said closed position.

10. The air treatment system of claim 9 wherein said outer surface include a tooth, said tooth interacting with said locking pin to secure said clip is in said closed position.

11. The air treatment system of claim 9 wherein said outer surface defines a seat, said locking pin and said seat being interfitted when said clip is in said closed position.

12. The air treatment system of claim 11 wherein said outer surface includes a stop, said stop configured to engage with said locking pin to limit a range of motion of said clip.

13. The air treatment system of claim 4 wherein said filter include two clips arranged on opposite sides of said frame;

and

wherein said filter includes a catch protruding from said frame remote from said clips.

14. The air treatment system of claim 4 wherein said filter includes one clip positioned near a top center of said filter.

15. A filter for an air treatment system comprising:

a frame having a top, a bottom and a pair of opposed sides;

a filter media supported by said frame;

a catch protruding from said frame; and

a retaining clip rotatably mounted to said frame, said clip being manually movable between an open position and a closed position, said clip being configured to interact with a filter housing to draw the filter into the filter housing and to secure the filter in the filter housing when in the closed position;

wherein said catch is disposed a said bottom of said frame and said clips are disposed toward said top of said frame.

16. The filter of claim 15 wherein said clip includes a hook configured to engage the filter housing when in said closed position.

17. The filter of claim 16 wherein said hook is configured such that said hook is required to deform as said clip is moved from said open position to said closed position, said deformation creating a snap-fit engagement resisting movement of said clip into and out of said closed position.

18. The filter of claim 16 further including a locking pin disposed adjacent said clip, said clip including an outer surface configured to interact with said locking pin when said clip is in said closed position creating a snap-fit engagement resisting movement of said clip into and out of said closed position.

19. The filter of claim 18 wherein said outer surface include a tooth and said locking pin defines a recess, said tooth and said recess being interfitted when said clip is in said closed position.

20. The filter of claim 18 wherein said outer surface defines a seat, said locking pin and said seat being interfitted when said clip is in said closed position.

21. The filter of claim 20 wherein said outer surface includes a stop, said stop configured to engage with said locking pin to limit a range of motion of said clip.
