Autonomous laundry washing and drying devices, systems, and methods of use
A method of autonomously washing and drying at least one deformable article with a combination washer and dryer includes receiving, at a controller in communication with the combination washer and dryer, a request to begin a washing and drying cycle, instructing a pivot motor to rotate the combination washer and dryer upward such that an opening of the combination washer and dryer faces upward to receive the at least one deformable article therein; instructing the pivot motor to pivot the loaded combination washer and dryer to a washing and drying angle in a range of between about 0 degrees to 20 degrees from horizontal, and instructing, in response to a sensor output signal indicating the combination washer and dryer being pivoted to the washing and drying angle, an autonomous door loader disposed adjacent to and detached from the combination washer and dryer to seat a removable door in the opening.
1 . A method of autonomously washing and drying at least one deformable article with a combination washer and dryer, comprising:
receiving, at a controller in communication with the combination washer and dryer, a request to begin a washing and drying cycle;
instructing, in response to the request, a pivot motor to rotate the combination washer and dryer upward such that an opening of the combination washer and dryer faces upward, the pivoted opening being configured to receive the at least one deformable article therein;
determining, based on an output signal of a position sensor in communication with the pivot motor, that the opening faces upward;
instructing an autonomous loader disposed above the combination washer and dryer and in operable communication with the controller to release the at least one deformable article to the combination washer and dryer;
instructing the pivot motor to pivot the combination washer and dryer to a washing and drying angle in a range of between about 0 degrees to 20 degrees from horizontal; and
instructing, in response to the output signal indicating the combination washer and dryer being pivoted to the washing and drying angle, an autonomous door loader disposed adjacent to and detached from the combination washer and dryer to seat a removable door in the opening.
2 . The method of claim 1 , wherein the pivot motor is configured to rotate a pivot shaft aligned with a center of gravity of the combination washer and dryer, and wherein the pivot shaft is configured to engage a rigid frame in which the combination washer and dryer is suspended by at least two springs, and wherein instructing the pivot motor to rotate the combination washer and dryer comprises rotating the rigid frame.
3 . The method of claim 1 , wherein the combination washer and dryer is configured to rotate in a range between about 0 to 180 degrees from vertically upward to vertically downward, and wherein the output signal of the position sensor indicates rotational position.
4 . The method of claim 1 , wherein the position sensor comprises an accelerometer disposed on the combination washer and dryer, the accelerometer being in wired or wireless communication with the controller and being configured to at least one of detect a degree of rotation of the combination washer and dryer about a pivot axis and an imbalance of a spinning drum.
5 . The method of claim 1 , wherein a washing and drying routine comprises drawing water and one or more laundry chemicals into the combination washer and dryer, spinning the combination washer and dryer about a spin axis substantially perpendicular to the opening, draining wastewater out of the combination washer and dryer, and drawing air into an interior volume of the combination washer and dryer.
6 . The method of claim 1 , further comprising receiving an output signal from an alignment sensor in wired or wireless communication with the controller, the output signal being indicative of alignment of the removable door to the opening during seating.
7 . The method of claim 6 , wherein the alignment sensor comprises at least one of a camera, an optical break beam, a hall sensor, a proximity sensor, and an IR sensor.
8 . The method of claim 1 , further comprising
actuating one or more latches to a locked position attaching the removable door to the combination washer and dryer in a watertight mating; and
receiving a sensor signal indicative of the removable door being seated and latched.
9 . The method of claim 8 , further comprising executing, in response to receiving the sensor signal indicative of the removable door being seated and latched, a washing and drying routine.
10 . The method of claim 8 , further comprising, upon detecting completion of a washing and drying routine,
actuating the one or more latches to an unlocked position;
receiving an output signal from an alignment sensor in wired or wireless communication with the controller, the output signal being indicative of alignment of the autonomous door loader to the removable door;
instructing the autonomous door loader to remove the removable door from the opening outside of a clearance circle traced by the combination washer and dryer during rotation to an inverted position with the opening angled downward; and
instructing the pivot motor to invert the combination washer and dryer to the inverted position for dropping the washed and dried at least one deformable article from the combination washer and dryer.
11 . The method of claim 10 , wherein removal of the removable door from the opening comprises instructing a drive of an arm of the autonomous door loader to extend the arm, actuating one or more end effectors of the arm configured to engage the removable door, and instructing the drive of the arm to retract the arm with the removable door detached from the opening and engaged with the one or more end effectors.
12 . The method of claim 1 , wherein the autonomous door loader is configured to transit on a rail disposed adjacent to and detached from a plurality of combination washer and dryers comprising the combination washer and dryer.
13 . The method of claim 1 , wherein instructing the autonomous door loader to seat the removable door in the opening comprises instructing a drive of an arm of the autonomous door loader to extend the arm and the removable door suspended thereby, actuating one or more end effectors of the arm configured to disengage from the removable door, and instructing the drive of the arm to retract the arm with the removable door detached from the disengaged one or more end effectors.
14 . The method of claim 1 , wherein the combination washer and dryer comprises one of a plurality of autonomous combination washer and dryers serviced by the autonomous door loader.
15 . The method of claim 14 , wherein the autonomous door loader comprises a driven carrier slidably engaged with a raised rail disposed adjacent the plurality of autonomous combination washer and dryers to reseat a removable door in an opening of one of the plurality of autonomous combination washer and dryers.
16 . The method of claim 15 , wherein the driven carrier is configured to transit along the raised rail and retrieve, hold, and reseat a removable door in an opening of any one of the plurality of autonomous combination washer and dryers.
