Thehome appliance 10 includes ahousing 12 that may house a treatingchamber 14 for receiving an article for treatment according to an automatic cycle of operation. Thehousing 12 may include a cabinet, unitary or not, as well as a frame or chassis, which may or may not have panels attached to it. The treatingchamber 14 may include anopen face 16 that may be selectively closed by adoor 18. More specifically, thedoor 18 may be movably mounted to thehousing 12 to selectively close the treatingchamber 14. Thedoor 18 has been illustrated as being in an opened position, shown in phantom, and a closed position. Thedoor 18 has been illustrated as moving in a pivoting manner to close theopen face 16. Thearrow 19 indicates the direction thedoor 18 moves when it moves in an open direction. - An
actuator 20 may be operably coupled with thedoor 18 to move thedoor 18 through the various operational positions, e.g. opened and closed, of the door. Theactuator 20 may also be configured to automatically move thedoor 18, which may be in response to a predetermined condition. For example, theactuator 20 may move thedoor 18 from a closed position of thedoor 18 to an opened position of thedoor 18. This may include that theactuator 20 may move thedoor 18 to a partially opened position or a fully opened position. Theactuator 20 may also be configured to move thedoor 18 towards a closed position including that theactuator 20 may close thedoor 18. Theactuator 20 may move thedoor 18 in response to input from a control system of thehome appliance 10. Theactuator 20 may be any suitable type ofactuator 20 operably coupled with thedoor 18 to move thedoor 18 including that theactuator 20 may include a motor operably coupled with thedoor 18 or a biasing device, such as a spring. For example, in the case of a motor, the motor may be configured to move thedoor 18 to an opened position where thedoor 18 may be fully open. The motor may also be configured to move thedoor 18 from the opened position to the closed position. By way of further example, in the case of a spring, the spring may be configured to move thedoor 18 to an opened position including that of a partially opened position. While theactuator 20 has been shown being positioned below thedoor 18, it will be understood that theactuator 20 may be located in any suitable location. - One or
more components 22 may be included in thehome appliance 10 andsuch components 22 may be controlled by acontroller 24 to execute the cycle of operation. Thehome appliance 10 may be any suitable home or domestic appliance that performs a particular job in a home, including those relating to cleaning, cooking, or food preservation. While theappliance 10 has been illustrated generically, the home appliance may be any suitable home appliance, including, but not limited to a dishwasher, a refrigerator, a freezer, a range, a stove, an oven, a cooktop, a clothes washing machine, a clothes dryer, a combination washing machine and dryer, a dispensing dryer, a tumbling or stationary refreshing/revitalizing machine, an extractor, a non-aqueous washing apparatus, a revitalizing machine, etc. All of these examples of home appliances may receive one or more article(s) and may include any number ofcomponents 22 that may be controlled so that thehome appliance 10 may perform a useful cycle of operation on the article(s). - The control system may control the operation of the

For example, abutton 27 may be included and may be operably coupled with theactuator 20 and thecontroller 24 to prompt operation of theactuator 20 upon a user selecting thebutton 27. More specifically, when thebutton 27 may be pressed by a user thedoor 18 may be opened or closed depending on its current position. - The
controller 24 may include the machine controller and any additional controllers provided for controlling any of thecomponents 22 of thehome appliance 10. For example, thecontroller 24 may include the machine controller and a motor controller. Many known types of controllers may be used for thecontroller 24. The specific type of controller is not germane to the invention. It may be contemplated that the controller may be a microprocessor-based controller that implements control software and sends/receives one or more electrical signals to/from each of the various working components to effect the control software. As an example, proportional control (P), proportional integral control (PI), and proportional derivative control (PD), or a combination thereof, a proportional integral derivative control (PID control), may be used to control the various components. - As illustrated in
FIG. 2 , thecontroller 24 may be provided with amemory 30 and a general purpose central processing unit (CPU) 32. Thememory 30 may be used for storing the control software, such as a set of computer-executable instructions, that may be executed by theCPU 32 in completing a cycle of operation using thehome appliance 10 and any additional software. Thecontroller 24 may be operably coupled with one ormore components 22 of thehome appliance 10 for communicating with and controlling the operation of thecomponent 22 to complete a cycle of operation. - The

One difference is thehome appliance 310 has been illustrated in the form of a clothes washer. Further, thedoor 318 has been illustrated as a slidingdoor 318 that slides within a portion of thehousing 312. The slidingdoor 318 may include a see through panel or window. It is contemplated that the sliding door may include multiple sliding panels including an outer panel that may be configured to protect the user from motion of a drum of thehome appliance 310 and an inner panel that seals the treatingchamber 314. Yet another difference is thatmultiple sensors 328, configured to sense a user at a predetermined location, have been included in thehome appliance 310. This may allow thehome appliance 310 to determine a presence of a user when the user is located at various locations near thehome appliance 310. This may also allow thehome appliance 310 to sense a movement of the user between two or more predetermined locations on thehousing 312 to determine a presence of the user. - Regardless of the type of home appliance and its specific sensors and actuators, each home appliance described above provides the structure necessary for the implementation of embodiments of a method of invention. Referring now to
FIG. 6 , a flow chart of amethod 400 for operating a laundry treating appliance, such as thehome appliance 10,home appliance 110,home appliance 210, orhome appliance 310, is illustrated. The sequence of steps depicted for this method is for illustrative purposes only, and is not meant to limit the method in any way as it is understood that the steps may proceed in a different logical order or additional or intervening steps may be included without detracting from the invention. Themethod 400 may be implemented in any suitable manner, such as automatically or manually, as a stand-alone phase or cycle of operation or as a phase of an operation cycle of the home appliance. While themethod 400 may be utilized with any suitable home appliance, themethod 400 will be described with respect to thehome appliance 310 for ease of explanation. - At 402, a presence of a user at a predetermined location with respect to the
home appliance 310 may be sensed, such as by one or more of thesensors 328. The predetermined location may be within a predetermined distance range from thehome appliance 310. Sensing the user may include sensing a body part of the user at the predetermined location. This may also include sensing a gesture made by the user at the predetermined location, which may include sensing a movement of the user between two or more predetermined locations on or near ahousing 312 of thehome appliance 310. Sensing the presence of the user at the predetermined location may be done in any suitable manner including by sensing a touch made by the user on thehome appliance 310. Sensing the touch may include sensing the touch on a predetermined portion of the home appliance such as adjacent one of more of thesensors 328. Sensing the presence of the user may alternatively include sensing the presence of an inanimate object indicative of a presence of the user. For example, this may include an RF chip (radio frequency chip) in a laundry basket or dish that is at the predetermined location. - At 404, movement of the
door 318 from a closed position to an opened position may be automatically initiated by thecontroller 324 based on the sensing at 402. Movement of thedoor 318 at 404 may include partially moving thedoor 318 to an opened position or fully moving thedoor 318 to the opened position. As will be understood from the home appliances described above, the door may be moved to an opened position in any suitable manner including that initiating movement of the door from the closed position to the opened position may include pivoting the door vertically, pivoting the door horizontally, or vertically sliding the door. - It will be understood that the method of operating the laundry treating appliance may be flexible and that the
method 400 illustrated is merely for illustrative purposes. For example, it is contemplated that the controller may also automatically move the door towards a closed position of the door. This may include sliding the door towards the closed position of the door or pivoting the door towards the closed position of the door. The moving the door towards a closed position may be in response to a user initiated stimulus or in response to it being determined that the user may no longer be at the predetermined location. It is also contemplated that the controller may receive an input signal from the user, such as through the user interface, and the automatic initiating of the movement of the door based thereon may be disabled. -
FIG. 7A illustrates ahand 340 of a user that may be sensed at a predetermined location, which may be adjacent any of thesensors 328. Further, the user may make a gesture by moving theirhand 340 in a direction indicated by thearrow 342. The twosensors 328 adjacent the upper left hand corner of thedoor 318 may sense the beginning movements of thehand 340 in a downward sweeping motion. This may prompt thecontroller 324 to begin to move thedoor 318 towards a partially opened position as illustrated inFIG. 7B . The user may continue to move theirhand 340 along the path formed by thearrow 342 between the two sets ofsensors 328. When thehand 340 finishes the gesture as illustrated inFIG. 7C , thehand 340 may be adjacent the twosensors 328 adjacent the lower right corner of thedoor 318. This may prompt thecontroller 324 to continue to move thedoor 318 downwards into a fully opened position. It is contemplated that thehome appliance 310 may be configured such that if the user gestured theirhand 340 in the opposite direction thedoor 318 may be automatically raised to the closed position. - It will be understood that the various sensors may be located at any suitable location on the home appliance in order to capture any suitable gesture.
FIG. 8A illustrates yet anotherhome appliance 510, which is similar to thehome appliance 310 previously described and therefore, like parts will be identified with like numerals increased by 200, with it being understood that the description of the like parts of thehome appliance 310 applies to thehome appliance 510, unless otherwise noted. One difference is that thesensors 528 are located adjacent a left side of thedoor 518. In such an instance the user may make a gesture by moving theirhand 540 in a direction indicated by thearrow 542. As thehand 540 is moved downwards along thesensors 528, thesensors 528 may output signals accordingly and thecontroller 524 may begin to move thedoor 518 downwards as illustrated inFIG. 8B . Thecontroller 524 may continue to move thedoor 518 downward as thehand 540 moves downward until thedoor 518 is fully open as illustrated inFIG. 8C . Thehome appliance 510 may be configured such that if the user gestured theirhand 540 in the opposite direction thedoor 518 may be automatically raised to the closed position. It may be understood that while a hand of the user has been described as being sensed a gesture utilizing another body part may alternatively be sensed. - The above embodiments provide a variety of benefits including that home appliances may be operated to automatically initiate movement of a door when a user is determined to be present near the home appliance. This may prove particularly useful when a user has his or her hands or arms loaded and may not be able to open the door to the home appliance. Further, the appliance may be touched to open the door and this may allow a user to bump the home appliance with a shoulder or foot to open the door.
