The present subject matter relates generally to door assemblies for an appliance.
Oven appliances generally include a cabinet that defines a cooking chamber for receipt of food articles for cooking and an opening for accessing the cooking chamber. Oven appliances also include a door rotatably mounted to the cabinet at the opening to permit selective access to the cooking chamber through the opening. In addition, oven appliances also include a gasket extending between the door and the cabinet at the opening of the cabinet when the door is in a closed position. The gasket can assist with insulating the cooking chamber and/or with containing cooking fumes within the cooking chamber. To ensure the door remains compressed or sealed against the gasket, certain oven appliances include a spring roller assembly that holds the door in the closed position through the engagement of, e.g., a roller and a strike plate.
However, opening the door can be a rather difficult task, because, for example, a user must pull a handle on the door with an amount of force sufficient to disengage the roller from the strike plate. More specifically, the spring roller assembly includes a spring, and the amount of force must be sufficient to compress the spring by a predetermined amount in order to disengage the roller from the strike plate. In addition, the amount of force must be sufficient to break the seal between the gasket and the door. Thus, opening the door may require a substantial amount of force.
Accordingly, an oven appliance with features for assisting with opening the door of an appliance, such as an oven appliance, would be useful.
The present disclosure relates to an appliance having a door assembly. In particular, the door assembly can assist with reducing an amount of force required to move a door of the appliance from a closed position to an open position. Additional aspects and advantages of the invention will be set forth in part in the following description, or may be apparent from the description, or may be learned through practice of the invention.
In a first exemplary embodiment, an appliance defining a vertical direction includes a door, a catch, and a door assembly. The door defines a cavity accessible through an opening. The catch may be spaced apart from the door along the vertical direction. The door assembly may include a latch assembly and a trigger. The latch assembly may include a latch movable along the vertical direction. The trigger may be coupled to the latch assembly. In addition, the trigger may be movable between a first position and a second position. When the trigger is in the first position, the latch may engage the catch. In contrast, when the trigger is in the second position, the latch may be spaced apart from the catch along the vertical direction.
In a second exemplary embodiment, an oven appliance defining a vertical direction includes a cabinet, a door, a handle, a catch, and a door assembly. The cabinet may define a cooking chamber configured for receipt of food items. In addition, the cabinet may define an opening at a front portion of the cabinet.

The insulated cabinet 12 extends between a top portion 14 and a bottom portion 16 along the vertical direction V. The cabinet 12 includes an interior surface 18 that defines a cooking chamber 20. The cooking chamber 20 is configured for the receipt of one or more food items to be cooked. The oven appliance 10 also includes a pair of doors 30 rotatably mounted on the cabinet 12 proximate an opening 22 to the chamber 20 defined by the cabinet 12. Thus, the oven appliance 10 is sometimes referred to as a French door style oven appliance.
The pair of doors 30 each include top and bottom walls 32 and 34, front and back walls 36 and 38, and opposing sidewalls 40, 42. The top and bottom walls 32, 34 are spaced apart from one another along the vertical direction V. The front and back walls 36, 38 extend between the top and bottom walls 32, 34 along the vertical direction. Further, the front and back walls 36, 38 are spaced apart from one another along the transverse direction T. The opposing sidewalls 40, 42 extend between the front and back walls 36, 38 along the transverse direction T. Further, the opposing sidewalls 40, 42 extend between the top and bottom walls 32, 34 along the vertical direction V. Still further, the opposing sidewalls 40, 42 are spaced apart from one another along the lateral direction L.
In operation, the pair of doors 30 are each configured for selectively shifting between an open position or configuration shown in
One or more gaskets 80 between the pair of doors 30 and the cabinet 12 provide for maintaining heat and cooking fumes within the cooking chamber 20 when the pair of doors 30 is in the closed position as shown in
Heating elements 90 and 92 are positioned within the cooking chamber 20 of the cabinet 12. The heating elements 90 and 92 are used to heat the cooking chamber 14 for both cooking and cleaning of the oven appliance 10. The operation of the oven appliance 10, including the heating elements 90 and 92, is controlled by one or more processing devices (not shown) such as a microprocessor other device that is in communication with such components.
The oven appliance 10 includes a control panel 100 comprising top and bottom walls 102, 104 and a front wall 106. The top and bottom walls 102 and 104 of the control panel 100 may be spaced apart from one another along the vertical direction V.

The latch assembly 140 also includes a rod 160 comprising a first end 162 and a second end 164. The first end 162 is disposed within the cavity 144 formed by the housing 142, and the second end 164 is disposed within the cavity 120 (
The latch assembly 140 further includes a spring 170 disposed within the cavity 144 formed by the housing 142. More specifically, the spring 170 is positioned between the bottom wall 152 of the latch 150 and the bottom wall 146 of the housing 142 along the vertical direction V. In addition, the spring 170 extends around the rod 160. As will be discussed below in more detail, the bottom wall 152 of the latch 150 compresses the spring 170 against the bottom wall 146 of the housing 142 when the latch 150 moves towards the bottom wall 34 (
The linkage arm 210 may define an aperture 216 positioned between the first end 212 and the second end 214. More specifically, the linkage arm 210 may be oriented such that a portion of the linkage arm 210 defining the aperture 216 is positioned within the cavity 54 formed by the mounting bracket 52. Further, the aperture 216 may be aligned with an aperture (not shown) formed in the mounting bracket 52, and a mechanical fastener (also not shown) may extend through the aperture formed in the mounting bracket 52 and the aperture 216 formed in the linkage arm 210. Accordingly, the linkage arm 210 may be coupled to the mounting bracket 52 via the mechanical fastener. Further, the first and second ends 212, 214 may each be rotatable about the aperture 216.
The linkage arm 210 may also define an opening or slot 218 positioned at the first end 212 of the linkage arm 210. The slot 218 may extend along the vertical direction V and, as will be discussed below in more detail, may prohibit inadvertent movement of the trigger 220 when the door 30 is moving from the open position to the closed position.
The trigger 220 includes a first end 222 and a second end 224. The first end 222 is positioned adjacent the second end 214 of the linkage arm 210. The second end 224 is spaced apart from the first end 222 along the vertical direction V. The trigger 220 defines a centerline axis 225 extending from the first end 222 to the second end 224 along the vertical direction V. The trigger 220 also includes an inner surface 226 and an outer surface 228. The inner surface 226 faces the handle 50, and the outer surface 228 faces the door 30. As discussed below in more detail, the trigger 220 is movable between a first position 230 (
In the first position 230, the latch 150 (
Additionally, as the latch 150 moves towards the bottom wall 146 of the housing 142, the second end 164 of the rod 160 moves within the slot 218 along the vertical direction V. More specifically, the second end 164 of the rod 160 moves towards the bottom wall 34 (
In an alternative embodiment, the first end 212 of the linkage arm 210 may be coupled to the second end 164 of the rod 160 via a flexible wire. The flexible wire may be uncompressed when the door 30 is in the open position. However, as the door 30 moves from the open position to the closed position, the flexible wire may become compressed between the bottom wall 146 of the housing 142 and the bottom wall 34 of the door 30. More specifically, as the catch 130 moves the latch 150 towards the bottom wall 146 of the housing 142 along the vertical direction V, the second end 164 of the rod 160 moves towards the bottom wall 34 of the door 30 along the vertical direction V. As such, the flexible wire becomes compressed between the bottom wall 146 of the housing 142 and the bottom wall 152 of the latch 150. Accordingly, the flexible wire absorbs motion of the latch 150 along the vertical direction V and prevents transfer of said motion to the linkage arm 210. Furthermore, since the flexible wire prevents movement of the linkage arm 210, the flexible wire prevents inadvertent movement of the trigger 220 towards the handle 50. As a result, the flexible wire prevents a user's hand from becoming pinned between the handle 50 and the trigger 220 when the user is moving the door 30 from the open position to the closed position.

However, for the embodiment of
As the trigger 220 rotates towards the handle 50, the second linkage arm 214 simultaneously rotates in the first direction 250 and moves the latch assembly 140 along the vertical direction V. In particular, the second linkage arm 214 pulls the first linkage arm 212 towards the bottom wall 34 of the door 30. Further, since the first linkage arm 212 is attached to the rod 160, the first linkage arm 212 pulls the latch 150 towards the bottom wall 34 of the door 30 along the vertical direction V. Still further, as the latch 150 moves towards the bottom wall 34 of the door 30, the latch 150, specifically the bottom wall 152 thereof, compresses the spring 170 against the bottom wall 146 of the housing 142.
The wire 320 includes a first end 322 and a second end 324. The first end 322 of the wire is coupled to the second end 164 of the rod 160. The wire 320 extends from the first end 322 and wraps around a portion of the first pulley 310. The wire 320 then extends through an opening formed in the front wall 36 of the door 30 and into the cavity 54 formed by the mounting bracket 52. The wire 320 then wraps around a portion of the second pulley 312 and extends into an interior chamber 58 defined by the handle 50. In particular, the wire 320 extends to the second end 324 which, as shown in
The trigger 330 is rotatable in a first direction 340. As the trigger 330 rotates in the first direction 340, the trigger 330 moves from a first position 350 (
