[0018] With respect to
[0019] The laundering appliance 10 includes a drum 58 that defines a cavity 62. The drum 58 is suspended within a body 66 of the laundering appliance 10. The body 66 may at least partially define the cavity 62. The drum 58 receives articles to be laundered (e.g., clothing) and is rotatable about a horizontal axis 70 or an angled rotational axis. As the laundering appliance 10 rotates the drum 58, air is provided to the cavity 62 of the drum 58. The air that is provided to the cavity 62 can be employed to dry and/or freshen the articles placed within the drum 58. In various operating modes, the air provided to the cavity 62 may be heated by a heating device 72 provided in the laundering appliance 10. During the various operating modes, lint or other debris may be dislodged or dissociated with the articles that are contained within the drum 58. The negative pressure or suction provided to the debris collection apparatus 14 by the blower assembly 22 can draw the dislodged or dissociated debris into the debris collection apparatus 14 and be removed from the cavity 62. The drum 58 may be provided with one or more perforations that can aid in allowing air to be introduced into the cavity 62 and/or the debris to exit the cavity 62. The body 66 may also include openings or apertures that assist in directing air through the perforations of the drum 58 and toward the debris collection apparatus 14. Ductwork can extend between a region proximate to the one or more perforations and the upper aperture 26 to direct the debris to the debris collection apparatus 14. In the depicted example, the debris collection apparatus 14 is positioned in a void 74 that is proximate to a lower region 78 of the laundering appliance 10. The void 74 is typically defined by an exterior surface 82 of the drum 58 and an interior surface 86 of the body 66.

[0021] Referring further to
[0022] In the example depicted in
[0023] With specific reference to
[0024] In various examples, the wiper motor 118 can be mounted to the collection assembly 18 in a manner that maintains the wiper motor 118 stationary and provides a surface upon which forces that oppose the rotation of the driveshaft 126 may act. Such an arrangement can ensure rotational motion provided by the wiper motor 118 is transmitted to the driveshaft 126 rather than causing the wiper motor 118 to rotate about the driveshaft 126. As the wiper motor 118 drives the driveshaft 126 to rotate, the wiper arm 124 is adjusted in its position relative to the filter 46. The rotation of the wiper 38 by the wiper motor 118 may be unidirectional, with the unidirectional rotation corresponding with the wiper arm 124 driving debris in a downward direction (i.e., toward the lower aperture 30) as a result of the unidirectional rotation. For example, when viewed from the position of the wiper motor 118, the wiper motor 118 may drive the driveshaft 126 in a counterclockwise direction in a unidirectional manner, thereby sweeping debris from the filter 46 for deposition into the bulk debris collection vessel 54. The helical shape of the wiper produces a screw-type motion that directs the captured lint particles toward the bulk debris collection vessel 54.
[0025] Referring now to
[0026] In the depicted example, the wiper motor 118 typically provides a bidirectional movement of the wiper arm 124 relative to the filter 46 such that the wiper arm 124 sweeps back-and-forth across the filter 46. Such motion of the wiper arm 124 can act to dislodge debris that has been captured by the filter 46 and thereby result in the deposition of the debris into the bulk debris collection vessel 54. In some examples, the wiper arm 124 may be provided with bristles that extend from a surface thereof to contact the filter 46. In such an example, the wiper arm 124 may alternatively be referred to as a brush.
[0027] With specific reference to
[0028] Referring again to
[0029] According to various examples of the present disclosure, the filter 46 can define a lattice structure that is arranged with a predetermined pore size or lattice density. The predetermined pore size or lattice density can be designed to capture particulate matter above a certain particle size. In some examples, the filter 46 may be of a wire mesh construction. Regardless of the material or arrangement of the filter 46, the filter 46 may be permanently fixed within the collection assembly 18. Said another way, the filter 46 may not be removable from the collection assembly 18 and/or the laundering appliance 10. A benefit of the present disclosure lies in an ease-of-use for a consumer. In particular, the debris collection apparatus' 14 discussed herein can be emptied of the debris collected therein with longer intervals between sequential emptying of the bulk debris collection vessel 54 than in laundering appliances 10 that do not employ the debris collection apparatus' 14 discussed herein. In various examples, the bulk debris collection vessel 54 can be a drawer or other suitable container that can be accessed from an exterior of the laundering appliance 10 for periodic disposal of accumulated debris deposits. By placing the debris collection apparatus 14 within the lower region 78 of the laundering appliance 10, debris can be prevented from being dislodged from the filter 46 and deposited onto an upper surface 150 of the body 66 during removal of debris, which can occur with alternative arrangements of laundering appliances. The bulk debris collection vessel 54 may be emptied after every cycle of operation (e.g., every drying cycle) of the laundering appliance 10 or after a plurality of cycles of operation (e.g., two, five, ten, or more cycles of operation).
[0030] Referring to
[0031] The various referenced measurements that are captured and/or recorded using the sensors can be compared to stored measurements (e.g., by the controller 154 referencing a memory 178). The stored measurements may be measurements that were stored within the appliance during manufacture, obtained when the cavity 62 was devoid of articles and/or measurements that were obtained at the beginning of the operating cycle. Regardless of the trigger used to actuate the wiper 38, the wiper 38 can dislodge debris that has been captured by the filter 46 in an effort to improve the operating efficiency of the laundering appliance 10. Debris that has been dislodged by the wiper 38 and/or captured by the hollow structure 34 can be deposited into the bulk debris collection vessel 54 once the blower motor 98 has been turned off or is no longer energized. When the blower assembly 22 is no longer operating, the negative pressure provided by the operation of the blower assembly 22 lessens or ceases and the flapper valve 42 can be actuated to an open position by gravity or a flapper motor.
[0032] In the various configurations discussed herein, the wiper 38 can be operated to dislodge debris captured by the filter 46 once the blower motor 98 has been disengaged and the flapper valve 42 has been placed in the open position. Accordingly, the dislodged debris can fall directly into the bulk debris collection vessel 54 from the filter 46. It is contemplated that the wiper 38 may be operated while the blower motor 98 is engaged such that debris dislodged from the filter 46 may accumulate on the closed flapper valve 42. In such an example, the dislodged debris is deposited from the flapper valve 42 into the bulk debris collection vessel 54 once the blower motor 98 is disengaged. It is also contemplated that the controller 154 may disengage the blower motor 98 if the controller 154 determines that debris has accumulated on the filter 46 to an extent that an operating efficiency of the laundering appliance 10 may benefit from dislodging the debris. For example, one of the current sensors 174 may sense an increase in a current drawn by the blower motor 98 and thereby indicate to the controller 154 that the blower motor 98 may be experiencing a resistance to air flow. In such a situation, the controller 154 may disengage the blower motor 98 and operate the wiper 38. With the negative pressure decreased, either by decreased air flow as a result of debris accumulation or disengagement of the blower motor 98, the flapper valve 42 is placed in the open position or dislodged debris can be deposited into the bulk debris collection vessel 54.
[0033] It is contemplated that the various configurations discussed above can be altered or combined. For example, the wiper 38 can direct debris laterally or at an angle. However, it may be beneficial to arrange the upper aperture 26 vertically above the lower aperture 30. In such an example, operation of the wiper 38 may dislodge debris from the hollow structure 34 and/or the filter 46 in a manner that causes the dislodged debris to fall immediately toward the flapper valve 42 such that the dislodged debris can be deposited into the bulk debris collection vessel 54. It is also contemplated that airflow can move in alternative manners than the configurations shown, depending upon the positioning of air inlet(s) and the outlet 106.
