Title: Door handle for a washing machine or dryer appliance

Description:
FIELD OF THE INVENTION 
     The present subject matter is directed to door handles, e.g., for washing machine or dryer appliances. 
     BACKGROUND OF THE INVENTION 
     Washing machine appliances and dryer appliances generally include a cabinet that has a drum rotatably mounted therein. An opening defined by the cabinet permits access to a chamber defined by the drum. Articles to be washed or dried respectively are placed within the chamber through the opening. 
     To permit selective access to the chamber, a door is rotatably mounted to the cabinet with a hinge such that the door may rotate between an open configuration and a closed configuration. For example, a user can pull on a handle of the door in order to open the door. To close the door, the user can push on the handle or on the door&#39;s outer surface. To assist in opening and closing the door, the handle can be positioned on the door on an opposite side from the hinge. The further the distance between the handle and the hinge, the less the amount of force required for a user to open and/or close the door. 
     Horizontal axis washing machine and dryer appliances are preferred by certain consumers. In horizontal axis washing machine and dryer appliances, the drum rotates about a substantially horizontal axis within the cabinet. In such appliances, the door permitting access to the chamber defined by the drum is generally mounted to a front panel of the cabinet. 
     In addition, washing machine appliances and dryer appliances can be sold in matching pairs. In a matching pair, the washing machine appliance and dryer appliance can have a substantially similar appearance. Thus, for example, in a matching horizontal axis washing machine and dryer appliance pair, the doors of the appliances can be mounted to a respective front panel of the appliances&#39; cabinets and can have a substantially similar appearance. Generally, in a matching pair, the appliances&#39; doors are mounted such that the door of the washing machine appliance rotates open in one direction and the door of the dryer appliance rotates open in an opposite direction. Thus, in such pairs, the doors&#39; handles are generally mounted on opposite sides relative to one another. However, the doors can be mounted in other configurations and may be provided with an option for the consumer to change the hinge side as desired. 
     Because it may be desirable for doors of the washing machine appliance and the dryer appliance to appear similar in a matching appliance pair and because doors can be mounted differently within the matching pair (i.e., the doors on the appliances may rotate in opposite directions), a door that may be mounted to a washing machine appliance or a dryer appliance in a matching pair and have a substantially similar appearance on both of the appliances would be useful. However, because the doors&#39; handles are generally mounted on opposite sides of the appliance, a door with a handle that may be mounted to a washing machine appliance or a dryer appliance in a matching pair and have a substantially similar appearance on both of the appliances would also be useful. 
     In addition, certain handles for washing machine and dryer appliance doors can be visually distracting and/or unappealing to potential consumers. For example, a large, bulky handle attached to the outer surface of the door can be unappealing. Thus, a handle for a washing machine or dryer appliance door that is visually appealing and/or unobtrusive would be advantageous. However, a handle should not be unobtrusive to the extent that the handle is difficult to find and/or operate. Thus, a handle for a washing machine or dryer appliance door that is visually appealing and/or unobtrusive while also providing a highly visual indicator of the position and intent of the handle would be beneficial. 
     Also, handles for washing machine and dryer appliance doors can be used frequently. Thus, such handles can require a durable fastening and/or mounting mechanism to secure the handles to doors. Accordingly, a handle for washing machine and dryer appliance doors with features for durably mounting the handle to the doors would be useful.

In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents. 
       FIG. 1  illustrates an exemplary horizontal axis washing machine appliance  100 . However, while described in the context of a specific embodiment of horizontal axis washing machine appliance  100 , using the teachings disclosed herein it will be understood that horizontal axis washing machine appliance  100  is provided by way of example only. Other washing machine appliances having different configurations, different appearances, and/or different features may also be utilized with the present subject matter as well. 
     Washing machine appliance  100  has a cabinet  102  with a drum  120  rotatably mounted therein. Cabinet  102  extends between a first side  150  and a second side  152 . A motor (not shown) is in mechanical communication with drum  120  in order to selectively rotate drum  120  (e.g., during an agitation or a rinse cycle of washing machine appliance  100 ). Drum  120  defines a wash chamber  122  that is configured for receipt of articles for washing. Ribs  126  extend from drum  120  into wash chamber  122 . Ribs  126  assist agitation of articles disposed within wash chamber  122  during operation of washing machine appliance  100 . For example, ribs  126  may lift articles disposed in drum  120  during rotation of drum  120 . Drum  120  also defines a plurality of holes  124 . Holes  124  are configured to permit a flow of wash fluid between an interior of drum  120  and an exterior of drum  120 . 
     Cabinet  102  of washing machine appliance  100  has a front panel  104 . A detergent drawer  106  is slidably mounted within front panel  104 . Detergent drawer receives detergent and directs said detergent to wash chamber  122  during operation of appliance  100 . Front panel  104  defines an opening  105  that permits user access to wash chamber  122  of drum  120 . A door  130  is mounted to front panel  104  with a hinge  140 . A latch with a male latch portion  254  and a female latch portion  256  is configured for selectively securing door  130  in a closed configuration (i.e., a configuration in which door  130  is positioned adjacent front panel  104 ). 
     Door  130  provides selective access to wash chamber  122 . A user may selectively adjust door  130  between a closed positioned (not shown) and an open position (shown in  FIG. 1 ) in which the user may access wash chamber  122  of drum  120 . A user may adjust door  130  between the open and closed configurations by rotating door  130  about hinge  140 . For example, to open door  130  from closed configuration, the user may pull on handle  200  in order to rotate door  130  open. Handle  200  is discussed in greater detail below. Hinge  140  is mounted to cabinet  102  on second side  152  of cabinet  102  opposite of handle  200  that is positioned on first side  150  of cabinet  102 . 
     Front panel  104  also includes a control panel  110  with a plurality of input selectors  112 . Control panel  110  and input selectors  112  collectively form a user interface input for operator selection of machine cycles and features. A display  114  of control panel  110  indicates selected features, a countdown timer, and/or other items of interest to appliance users. 
     Operation of washing machine appliance  100  is controlled by a controller or processing device (not shown), that is operatively coupled to control panel  110  for user manipulation to select washing machine cycles and features. In response to user manipulation of control panel  110 , the controller operates the various components of washing machine appliance  100  to execute selected machine cycles and features. 
     In an illustrative embodiment, laundry items are loaded into wash chamber  122 , and washing operation is initiated through operator manipulation of input selectors  112 . Drum  120  is filled with water and detergent to form a wash fluid. One or more valves (not shown) can be controlled by washing machine appliance  100  to provide for filling drum  120  to the appropriate level for the amount of articles being washed. Once drum  120  is properly filled with fluid, the contents of wash chamber  122  are agitated with ribs  126  for cleansing of laundry items in drum  120 . 
     After the agitation phase of the wash cycle is completed, drum  120  is drained. Laundry articles can then be rinsed by again adding fluid to drum  120 , depending on the particulars of the cleaning cycle selected by a user, ribs  126  may again provide agitation within wash chamber  122 . One or more spin cycles may also be used. In particular, a spin cycle may be applied after the wash cycle and/or after the rinse cycle in order to wring wash fluid from the articles being washed. During a spin cycle, drum  120  is rotated at relatively high speeds. 
       FIGS. 2 and 3  provide perspective views of a dryer appliance  300  according to an exemplary embodiment of the present subject matter. However, while described in the context of a specific embodiment of dryer appliance  300 , using the teachings disclosed herein it will be understood that dryer appliance  300  is provided by way of example only. Other dryers having different appearances and different features may also be utilized with the present invention as well. 
     The dryer appliance  300  includes a main housing or cabinet  310  with a drum  390  rotatably mounted therein. Cabinet  302  extends between a first side  314  and a second side  316 . Drum  390  defines a drying chamber  392  configured for receipt of articles for drying. A motor (not shown) rotates drum  390  about an axis A H . Drum  390  is generally cylindrical in shape and defines a plurality of holes  391 . An opening  313  is defined by drum  390  in order to allow a user to access to drying chamber  392 , e.g., for loading and unloading of articles (e.g., clothing and/or other fabrics) into drying chamber  392 . 
     Cabinet  310  has a door  340  rotatably mounted to front panel  312  with a hinge  350  adjacent opening  313 . Hinge  350  is mounted to cabinet  310  on first side  314  of cabinet  310  opposite of handle  200  that is positioned on second side  316  of cabinet  310 . Door  340  provides selective access to drying chamber  392 . A user may selectively adjust door  340  between a closed positioned (shown in  FIG. 2 ) and an open position (not shown) in which the user may access chamber  392  of drum  390 . A user may adjust door  340  between the open and closed configurations by rotating door  340  about hinge  350 . For example, to open door  340  from closed configuration shown in  FIG. 2 , the user may pull on handle  200  in order to rotate door  340  open. Handle  200  is discussed in greater detail below. 
     A plurality of tumbling ribs  393  are provided within drum  390  to lift articles disposed therein and then allow them to tumble back to the bottom of drum  390  as drum  390  rotates. Drum  390  also includes a rear wall  395  rotatably supported within cabinet  310  by a suitable fixed bearing. Rear wall  395  can be fixed or can be rotatable. Plurality of holes  391  receive hot air that has been heated by a heating system  396 . Air is drawn from drum  390  by a blower fan  398 . The air passes through a lint or screen filter  399  which traps lint particles. As the air passes from the blower fan  398 , it is passed into the heating system  396 . Heated air exits heating system  396  and returns to drum  390 . After they have been dried, the articles are removed from drum  390  via opening  313 . 
     A cycle selector knob  304  is mounted on front panel  312  and is in communication with a processing device or controller (not shown) connected with a user interface panel  302 . Signals generated in the controller operate the drum drive system and heating system  396  in response to the user manipulation of the selector knobs  304 . Alternatively, a touch screen type interface may be provided. As used herein, “processing device” or “controller” may refer to one or more microprocessors or semiconductor devices and is not restricted necessarily to a single element. The processing device can be programmed to operate dryer appliance  300  according to methods well known in the art. The processing device may include, or be associated with, one or memory elements such as e.g., electrically erasable, programmable read only memory (EEPROM). 
       FIG. 4  illustrates door  130  of washing machine appliance  100  shown in  FIG. 1 . Door  130  defines an axial direction A, a circumferential direction C and a radial direction R. Door  130  includes a frame  210  and a cover  220 . Cover  220  is complementary in shape to frame  210 . Thus, in  FIG. 4 , frame  210  is substantially ring shaped, and cover  220  is similarly ring shaped. In alternative embodiments, frame  210  and cover  220  may have any other suitable alternative shape. In addition, door  130  may comprise a single element rather than a separate frame and cover. 
     Cover  220  is aligned with frame  210  and is positioned proximate to frame  210 . Frame  210  and cover  220  receive each other in a complementary manner and are secured together with a plurality of fasteners  270  in order to support a window  290 . Window  290  is disposed between frame  210  and cover  220  and permits viewing of the wash chamber  122  (shown in  FIG. 1 ). However, door  130  need not include a window, and, thus, need not permit viewing of wash chamber  122  in alternative embodiments. 
     Door  130  has an inner surface  212  positioned adjacent cabinet  102  when door  130  is the closed configuration, e.g., adjacent an exterior surface  108  of cabinet  102  when door  130  is the closed configuration. Door  130  also has an outer surface  222  spaced apart from inner surface  212  along the axial direction A. In  FIG. 4 , frame  210  includes inner surface  212 , and cover  220  includes outer surface  222 —e.g. a frontal surface. However, in alternative embodiments, inner and outer surfaces  212 , 222  may be defined in any suitable manner, e.g., as discussed above, door  130  may comprise a single element rather than a separate frame and cover. 
     Inner surface  212  has an outer perimeter  214 . Outer perimeter  214  corresponds to a perimeter of inner surface  212  that is most extremely positioned along the radial direction R to a central axis C A  that passes through a centroid of door  130  and is substantially perpendicular to horizontal axis H. In  FIG. 4 , because door  130  is substantially round and has a substantially circular profile, outer perimeter  214  is also substantially circular. However, door  130  may have any suitable profile and shape (e.g., square, rectangular, or oval), thus, outer perimeter  214  may have any suitable corresponding shape. 
     Similarly, outer surface  222  has an outer boundary—i.e., outer edge  224 . Outer edge  224  corresponds to a perimeter of outer surface  222  that is most extremely positioned along the radial direction R to the central axis C A  of door  130 . Like above, because door  130  is substantially round and has a substantially circular profile, outer edge  224  is also substantially circular. However, door  130  may have any suitable profile and shape, thus, outer edge  214  may have any suitable corresponding shape. 
     A sidewall  230  extends or spans between outer perimeter  214  and outer edge  224  along the axial direction A. Thus, sidewall  230  extends between inner surface  212  and outer surface  222  along the axial direction A and corresponds to a surface of door  130  that is most extremely positioned along the radial direction to the central axis C A  of door  130 . In  FIG. 4 , because door  130  is round, external surface  232  is positioned about the circumference of door  130 . Accordingly, in  FIG. 4 , sidewall  230  includes the outer circumferential surface  232  of door  130 . 
     A handle  200  is defined by door  130 . Handle  200  is defined by a recess  202  (shown in  FIG. 5 ) in sidewall  230 . As will be discussed in greater detail below, handle  200  also includes an insert  240  that is received within recess  202 . However, it should be understood that handle  200  may be defined solely by door  130  and need not include insert  240 . Handle  200  can assist a user in selectively adjusting door  130  between the open (shown in  FIG. 1 ) and closed (not shown) configurations. For example, when door  130  is in the closed configuration (not shown), the user can insert his or her fingers into handle  200  and pull on handle  200  in order to adjust door  130  to the open configuration (not shown). Thus, insert  240  has an interior surface  241  that is configured for the user to interact with, e.g., when opening door  130 . Inner surface  241  has a plurality of texture ribs  242  that can assist the user during interaction with handle  200 , e.g., by preventing slippage. 
     Handle  200  extends along the circumferential direction C between a top  204  and a bottom  206 . Top and bottom  204 , 206  are positioned adjacent and/or proximate sidewall  230 . Top and bottom  204 , 206  are positioned on sidewall  230  such that top and bottom  204 , 206  are about equidistant from a horizontal axis H along the circumferential direction C. As shown in  FIG. 4 , horizontal axis H bisects door  130 . However, other positions for handle  200  may be used as well. 
     Because horizontal axis H bisects door  30 , handle  200  is positioned on door  130  such that door  130  can be selectively adjusted between a first orientation and a second orientation. In the first orientation, door  130  is configured with handle  200  on first side  150  ( FIG. 1 ) of cabinet  102  ( FIG. 1 ). In the second orientation, door  130  is configured with handle  200  on second side  152  ( FIG. 1 ) of cabinet  102 . Door  130  can be adjusted from the first orientation to the second orientation by rotating door  130  about central axis C A  by about 180°. Because horizontal axis H bisects door  130 , handle  200  will be mirrored between first and second orientations and can be mounted to cabinet  102  with hinge  140  in both first and second orientations. 
     It is should be understood that door  130  ( FIG. 1 ) of washing machine appliance  100  is substantially similar to door  330  ( FIG. 2 ) of dryer appliance  300 . Thus, for example, doors  130 ,  340  may each have handle  200  with frame  210 , cover  220 , and insert  240 . However, doors  130 ,  340  may be constructed differently. For example, door  340  of washing machine appliance  100  may have has a plastic frame  210 , while door  340  of dryer appliance  300  has a metal frame  210  in order to resist the heat generated during operation of dryer appliance  300 . Also, door  130  of washing machine appliance  100  has a male portion  254  ( FIG. 1 ) of latch  250  mounted to door  130 , while door  330  of dryer appliance  300  may have a female portion  256  ( FIG. 1 ) of latch  250  mounted to door  330 . Also, window  290  may have a different shape between washing machine appliance  100  and dryer appliance  300 . 
     Handle  200  may be provided on both doors  130 ,  340  in order to provide a uniform appearance between washing machine appliance  100  and dryer appliance  300 . For example, door  130  of washing machine appliance  100  can match door  340  of dryer appliance  300  and maintain a uniform appearance because of their substantially identical construction despite door  130  of washing machine appliance  100  opening in a first direction and door  340  of dryer appliance  300  opening in a second opposite direction. Thus, for example, washing machine appliance  100  and dryer appliance  300  may be sold as a washer-dryer pair with a uniform appearance and handle  200 . 
       FIGS. 5-8  illustrate inset  240  being mounted to cover  220  of door  130 . In  FIG. 5 , insert  240  is shown disposed outside of recess  202 . As may be seen in  FIG. 5 , insert  240  includes a lip  244 . Lip  244  projects away from insert  240  along the axial direction A and circumferential direction C such that lip  244  is substantially perpendicular to interior surface  241  (shown in  FIG. 4 ) of insert  240 . Lip  244  extends projects away from insert  240  between top  204  and bottom  206  of handle  200 . As described in greater detail below, lip  262  assists in securing insert  240  within recess  202 . 
     A plurality of tabs  246  projects from insert  260  along axial direction A. Like lip  244 , plurality of tabs  246  is substantially perpendicular to an interior surface  241  (shown in  FIG. 4 ) of insert  240 . Tabs  264  are distributed on insert  240  from top  204  to bottom  206  of handle  200  along circumferential direction C. Each of the tabs  246  is spaced apart from lip  244  along radial direction R such that a portion of sidewall  230  may be disposed between tabs  246  and lip  244  in order to assist in mounting insert  240  to cover  220  as discussed below. 
     As may be seen in  FIG. 5 , projections  248  are also defined by insert  240 . Projections  248  extend away from insert  240  along radial direction R such that projections  248  are substantially perpendicular to lip  244 . Projections  248  are configured for receipt by slots  208  defined by cover  220 . However, slots  208  can also be defined by frame  210  or any other part of door  130 . Projections  248  are configured for receipt by slots  208  to assist in mounting insert  240  within recess  202  as discussed in greater detail below. 
     In  FIG. 6 , insert  240  is disposed in recess  202  (shown in  FIG. 5 ). As may be seen in  FIG. 7 , when insert  240  is placed in recess  202 , lip  244  is positioned adjacent sidewall  230  such that lip  244  is disposed substantially flush with exterior surface  232 . Alternatively, lip  244  can also be mounted over exterior surface  232 . Turning back to  FIG. 6 , when insert  240  is disposed within door  130 , tabs  246  are also disposed adjacent sidewall  230 . Thus, sidewall  230  is disposed between tabs  246  and lip  244  (shown in  FIG. 7 ). During insertion of insert  240  into recess  202 , tabs  246  deform sidewalls  230 . For example, tabs  246  are angled such that when insert  240  is pressed into recess  202  along radial direction R, sidewall  230  slides up tabs  246  until sidewall  230  snaps into place between tabs  246  and lip  244 . By disposing a portion of door  130  between lip  244  and tabs  246 , insert  240  can be securely mounted within recess  202  (shown in  FIG. 6 ). 
     In addition, when insert  240  is placed in recess  202 , projections  248  are received by slots  208 . When projections  248  are received by slots  208 , projections  248  assist in mounting insert  240  within recess  202 . For example, when the user pulls on insert  240  along axial direction A, projections  248  assist in transferring the force to door  130  and preventing insert  240  from moving within recess  202 . Projections  248  also assist in aligning insert  240  during installation within recess  202 . 
     Insert fasteners  272  are configured for assisting in selectively mounting insert  240  within recess  202 . Insert fasteners  272  may extend through insert  240  into cover  220  along axial direction A in order to secure insert  240  to cover  220 . It should be understood that, insert fasteners  272  are not required to secure insert  240  to cover  220 . Alternative mechanisms may also be used to secure insert  240  to cover  220 , e.g., frame fasteners  270 . 
     In  FIG. 6  a latch  250  is shown ready for mounting to insert  240  with latch fasteners  274 . In  FIG. 6 , latch  250  is a male latch portion  254  ( FIG. 1 ) with a corresponding female latch portion  256  ( FIG. 1 ) mounted to cabinet  102  of washing machine appliance  100  ( FIG. 1 ). However, in alternative embodiments, latch  250  may be a female latch portion with a corresponding male latch portion mounted to cabinet  102 . As described in greater detail below, latch  250  is configured for selectively maintaining door  130  in the closed configuration. 
     Latch fasteners  274  are configured for selectively securing latch  250  to insert  240 . However, in alternative embodiments, latch  250  may be mounted to any other suitable component, e.g., door  130 , cover  220 , and/or frame  210 . Latch fasteners  274  may extend through latch  250  into insert  240  in order to secure latch  250  to inert  240 . Alternative mechanisms may also be used to secure latch  250  to insert  240 , e.g., clips or glue. By securing latch  250  to insert  240 , when a user opens door  130  by pulling on insert  240 , force applied by the user to open door  130  is transferred directly to latch  250  from insert  240  via latch fasteners  274  rather than through other components of door  130 . 
     In  FIG. 7 , cover  220  is shown ready to be mounted to frame  210 . To mount cover  220  to frame  210 , a plurality of frame fasteners  270  are selectively extended through cover  220  into frame  210 . Alternative mechanisms may also be used to secure cover  220  to frame  210 . As may be seen in  FIG. 7 , latch  250  can extend through frame  210  from insert  240 . 
     In  FIG. 8 , cover  220  is shown mounted to frame  210  with fasteners  270 . When cover  220  is secured to frame  210  with frame fasteners  270 , window  290  is held in place between cover  220  and frame  210 . Also shown in  FIG. 8 , latch  250  extends from door  130 . Latch  250  has a tip  252  that is disposed away from door  130 . Tip  252  is configured for receipt by female portion  256  of front panel  104  (shown in  FIG. 1 ). When tip  252  is received by cabinet  102 , door  130  can be selectively secured in the closed configuration. However, as discussed above, latch  250  may be a female latch portion and, thus, be configured for receipt of tip  252  that extends from front panel  104  of cabinet  102
