DETAILED DESCRIPTION

Example embodiments will now be described more fully with reference to the accompanying drawings.
Turning to the figures, a combination washer/dryer machine is illustrated and designated with the reference numeral 10. The combination washer/dryer machine 10 includes a cabinet 12 with a plurality of panels 14. The controller panel 20 is illustrated on the front panel 16 of the cabinet 12. The combination washer/dryer 10 includes a tub 30 and a drum 32 rotatably positioned inside of the tub 30. A washing circuit 34 is coupled with the tub 30. Additionally, a drying circuit 36 is illustrated coupled with the tub 30. Thus, heated air is moved into the drum 32 and exited to ambient surrounding through the desired duct work 38.
A lint filter assembly 40 is positioned into the heating duct work 38. The lint filter assembly 40 includes a housing 42 that is positioned into and coupled with the duct work 38. The housing 42 receives a lint catcher 44. The lint catcher 44 includes a frame 46 that has a two piece design with a bowl 48 and a lid or cover 50. As illustrated, the catcher 44 has an overall rectangular trapezoidal design for sliding into the housing 42. The bowl 48 includes wall 52 that surrounds a lattice work 54 that includes a screen 56. The wall 52 includes an opening 58 that abuts a portion of the duct so that the housing 42 receives heated air from the tube 30. The heated air enters into the lint catcher 44, where the lint is retained in the lint catcher 44, then exits through the housing 42 to ambient.
The lid 50 includes lattice work 62 and a screen 64. The lid 50 is hinged to the bowl 48 to enable the lid 50 to be moved away from the bowl 48 to enable access into the catcher 44 to remove the lint. Thus, the lint can be removed from the bowl 48 and lid 50.
The bowl 48 and lid 50 are manufactured from a plastic material. Preferably, a metallic strip 66 is co-molded into the lid 50. Magnets 68 are likewise co-molded into the bowl wall 52 to enable a magnetic closure between the lid 50 and the bowl 48. Thus, this retains the lid 50 onto the bowl 48 when it is positioned inside of the housing 42. Additionally, the magnets 68 and metallic strips 66 could be positioned into the other element.
A cover is 70 positioned onto a front portion of the wall 52 of the lint catcher 44. The cover 70 is accessible from outside of the cabinet 12. This enables the lint catcher 44 to be withdrawn from the housing 42. The cover 70 includes a handle 72 or opening that enables the user to grasp the cover 70 and remove the lint catcher 44 from the housing 42.
Turning to FIG. 3 , the cover 70 is illustrated with a seal 80. The seal 80 includes an attachment portion 82, a bulb portion 84 and a pocket 86 to retain a magnetic strip 88. The attachment portion 82 is secured into the cover 70 via a channel in the cover 70. The bulb portion 84 provides movement of the cover 70 when the magnetic strip 88 contact the cabinet 12. The bulb portion 84 could have a different cross-section depending upon the desired fit of the seal 80 on the cover 70. The magnetic strip 88 provides a positive retention or locking force of the lint filter assembly 40 in the cabinet 12.
Turning to FIGS. 5-7 , an additional mechanism 90 is illustrated to retain the lint catcher 44 within the housing 42. The mechanism 90 can be a mechanical push/push grab latch device or a magnetic push/push latching device.'
As illustrated in FIG. 6 , a mechanical latching device is illustrated. Here, the base 92, attached to the housing 42, includes fingers 94 that receive a ball 96 attached to the catcher 44. As the ball 96 is pushed into the fingers 94, the fingers 94 retract in the base 92. The fingers 94 are held in the base 92 with the ball 96. Thus, the catcher 44 is retained or locked with the housing 42.
An additional push on the cover 70, in turn, pushes the ball into the base 92. This releases the fingers 94 from within the base which, in turn, releases the ball 96 from the fingers 94. Thus, this enables the catcher 44 to be withdrawn from the cabinet 12.
FIG. 7 illustrates a magnetic push-push device. The magnetic device 100 has a base 102 with a movable shaft 104. A metallic striker plate 106 would be positioned onto the catcher 44. As the lint catcher 44 is pushed into the housing 42, the shaft 104 would retract into the base 102 mounted on the housing 42. The magnet 108 would retain the striker plate 106 on the device 100. As the cover 30 is pushed in, the shaft is released from the base 100 to enable the lint catcher 44 to be withdrawn from the housing 42 and cabinet 12.
FIGS. 8 and 8A illustrate an additional catcher 44′. The catcher of FIG. 8 is substantially the same as that illustrated in FIG. 2 except for the addition of one or more lint peelers 110. The lint peelers 110 are positioned adjacent the bottom near the lattice work 54 of the bowl 48. The peelers 110 may have an overall rectangular configuration and be ring shaped or solid. The peelers 110, as illustrated in FIG. 8A, as the lid 50 is opened, moves underneath the lint 112 to lift the lint from the bowl 48 lattice work 54 and screen 56. Thus, the lint 112 is scraped from the lattice work 54 and screen 52 to provide a lifted leading edge to enable removal of the lint 112 from the bowl 48.
Turning to FIG. 9 , an additional catcher 44 is illustrated. Here, a storage bin 120 is positioned between the frame 46 and the cover 70. The storage bin 120 enables detergent pods, dryer sheets, brushes or the like to be stored within the dryer in the bin 120. Upon removal of the catcher 44, the storage bin 120 would be accessible. Thus, a user would have access to the items in the bin 120. The storage bin 120 can have a box-like configuration with a cover 122 to enable access into the storage bin 120.
The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
