Description

FIELD OF THE INVENTION

The present subject matter relates generally to oven appliances, such as double oven range appliances.

BACKGROUND OF THE INVENTION

Double oven range appliances generally include upper and lower cooking chambers. A user of the double oven range appliances may conveniently utilize either or both of the upper and lower cooking chambers to cook food items. In certain double oven range appliance, the upper cooking chamber is smaller than the lower cooking chamber. Thus, the user may utilize the upper cooking chamber to cook smaller food items and the lower cooking chamber to cook larger food items.

Double oven range appliances also generally include two doors, one for the upper cooking chamber and another for the lower cooking chamber. The doors are generally rotatably mounted to a cabinet of the appliance with hinges. Thus, the user of the double oven range appliance may rotate the doors open on the hinges in order to access the upper and lower cooking chambers.

Hinges have certain drawbacks that may be inconvenient or undesirable to users. For example, removing food items from the upper cooking chamber can be difficult or awkward. In particular, the upper cooking chamber may be relatively small compared to the lower cooking chamber, and reaching into the upper cooking chamber to grasp and handle cookware therein can be difficult or awkward. In addition, monitoring the cooking of food items within the upper cooking chamber can be difficult due to poor visibility of the food items within the upper cooking chamber even when the door to the upper cooking chamber is open.

Accordingly, an oven appliance with features for facilitating access to food items within a cooking chamber of the oven appliance would be useful. In addition, an oven appliance with features for facilitating monitoring of food items within a cooking chamber of the oven appliance would be useful.

DETAILED DESCRIPTION

Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. 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.

FIGS. 1, 2, 3 and 4 provide perspective views of an oven range appliance 100 according to an exemplary embodiment of the present subject matter. In FIGS. 1, 2, 3 and 4, an upper door 121 of range appliance 100 is shown various positions and orientations, as discussed in greater detail below. As may be seen in FIGS. 1, 2, 3 and 4, range appliance 100 defines a vertical direction V, a lateral direction L and a transverse direction T. The vertical, lateral and transverse directions are mutually perpendicular and form an orthogonal direction system.

Range appliance 100 includes an insulated cabinet 110. Cabinet 110 extends between a top portion 111 and a bottom portion 112, e.g., along the vertical direction V. Thus, top and bottom portions 111, 112 of cabinet 110 are spaced apart from each other, e.g., along the vertical direction V. Cabinet 110 also extends between a first side portion 113 and a second side portion 114, e.g., along the lateral direction L. Thus, first and second side portions 113, 114 of cabinet 110 are spaced apart from each other, e.g., along the lateral direction L. Cabinet 110 further extends between a front portion 115 and a back portion 116, e.g., along the transverse direction T. Thus, front and back portions 115, 116 of cabinet 110 are spaced apart from each other, e.g., along the transverse direction T.

Range appliance 100 includes a cooktop 130 positioned at or adjacent top portion 111 of cabinet 110. Cooktop 130 includes various heating elements 132, such as gas burners, electric resistance elements, induction elements, etc., that are configured for heating cookware positioned thereon. As may be seen in FIG. 1, cabinet 110 also defines an upper cooking chamber 120 and a lower cooking chamber 124. Thus, range appliance 100 is generally referred to as a double oven range appliance. As will be understood by those skilled in the art, range appliance 100 is provided by way of example only, and the present subject matter may be used in any suitable oven appliance, e.g., a single oven range appliance, a single wall oven appliance, a double wall oven appliance, etc.

Upper cooking chamber 120 is positioned at or adjacent top portion 111 of cabinet 110. Conversely, lower cooking chamber 124 is positioned at or adjacent bottom portion 112 of cabinet 110. Thus, upper and lower cooking chambers 120, 124 are spaced apart from each other along the vertical direction V. Upper and lower cooking chambers 120, 124 can have any suitable size relative to each other. For example, as shown in FIG. 1, upper cooking chamber 120 may be smaller than lower cooking chamber 124.

Upper and lower cooking chambers 120, 124 are configured for receipt of one or more food items to be cooked. Range appliance 100 includes an upper door 121 and a lower door 125 that are attached or coupled to cabinet 110, e.g., with slide assemblies and hinges as discussed in greater detail below, in order to permit selective access to upper cooking chamber 120 and lower cooking chamber 124, respectively. Handles 123, 127 are mounted to upper and lower doors 121, 125 to assist a user with opening and closing doors 121, 125 in order to access cooking chambers 120, 124. As an example, a user can pull on handle 123 mounted to upper door 121 to open or close upper door 121 and access upper cooking chamber 120. Glass window panes 122, 126 provide for viewing the contents of upper and lower cooking chambers 120, 124 when doors 121, 125 are closed and also assist with insulating upper and lower cooking chambers 120, 124. Heating elements such as electric resistance heating elements, gas burners, microwave elements, etc., are positioned within upper and lower cooking chambers 120, 124 of cabinet 110 for heating upper and lower cooking chambers 120, 124. In particular, heating element 160 (FIG. 6) is positioned within upper cooking chamber 120 and is configured for selectively heating upper cooking chamber 120.

A control panel 140 of range appliance 100 is positioned at top portion 111 and back portion 116 of cabinet 110. Control panel 140 includes user inputs 142. Control panel 140 provides selections for user manipulation of the operation of range appliance 100. For example, a user can touch control panel 140 to trigger one of user inputs 142. In response to user manipulation of user inputs 142, various components of the range appliance 100, such as heating element 160, can be operated.

As may be seen in FIGS. 1, 2, 3 and 4, upper door 121 may be positioned and oriented in a variety of configurations and positions. For example, door 121 is shown in a closed position and a vertical configuration in FIG. 1. As another example, upper door 121 is shown in the closed position and a peak configuration in FIG. 2. In FIG. 3, upper door 121 is shown in an open position and the peak configuration. Conversely, upper door 121 is shown in the open position and the vertical configuration in FIG. 4. A user of range appliance 100 may adjust upper door 121 between the various positions and configurations shown in FIGS. 1, 2, 3 and 4. For example, the user may grasp handle 123 of upper door 121 and move upper door 121, e.g., along the transverse direction T, between the closed and open positions and/or pivot upper door 121, e.g., on an axis that is parallel to the lateral direction L, between the vertical and peak configurations.

To permit movement of upper door 121, e.g., along the transverse direction T, range appliance 100 includes a pair of slide assemblies or slide rails 172 that slidably couple upper door 121 to cabinet 110. Slide assemblies 172 are mounted to cabinet 110 at or adjacent upper cooking chamber 120. Each slide assembly of slide assemblies 172 are positioned at a respective one of the first and second side portions 113, 114 of cabinet 110. In particular, slide assemblies 172 include a first slide assembly or set of slide rails 174 and a second slide assembly or set of slide rails 176. First slide assembly 174 is mounted to cabinet 110 at or adjacent first side portion 113 of cabinet 110, and second slide assembly 176 is mounted to cabinet 110 at or adjacent second side portion 114 of cabinet 110.

First and second slide assemblies 174, 176 may be a full extension draw slide and may include a first or outer slide rail, a second or inner slide rail and a third or intermediate slide rail. The outer slide rail is fixed relative to cabinet 110, e.g., with fasteners or any other suitable mechanism. The inner slide rail is mounted to upper door 121. Thus, the inner slide rail may be fixed relative to upper door 121. The inner slide rail is received within the intermediate slide rail, and the intermediate slide rail is received within the outer slide rail. The intermediate slide rail and the inner slide rail are slidable or moveable along the transverse direction T relative to the outer slide rail (e.g., and cabinet 110). In addition, the inner slide rail is slidable or moveable along the transverse direction T relative to the intermediate slide rail. Thus, the intermediate slide rail may be slidable or movable relative to upper door 121. Ball bearings may extend between the outer slide rail and the intermediate slide rail may also extend between the intermediate slide rail and the outer slide rail in order to facilitate movement of the inner and intermediate slide rails along the transverse direction T relative to the outer slide rail. The inner and intermediate slide rails move linearly into and out of the outer slide rail, and the inner and intermediate slide rails may also telescope relative to each other. In alternative exemplary embodiments, first and second slide assemblies 174, 176 may be a partial extension drawer slide and may include only outer slide rail and inner slide rail, or first and second slide assemblies 174, 176 may include four or more total slide rails.

Slide assemblies 172 may be constructed to withstand high temperatures, e.g., exceeding six hundred degrees Fahrenheit. For example, bearings, e.g., ball bearings, of slide assemblies 172 may be coated with a graphite lubricant. As another example, the bearings, e.g., ball bearings, of slide assemblies 172 may be stainless steel bearings or chrome plated bearings. As yet another example, the slide rails of slide assemblies 172 may be stainless steel slide rails or chrome plated slide rails.

Slide assemblies 172 may be mounted to any suitable component of cabinet 110 and positioned at any suitable location on cabinet 110. For example, slide assemblies 172 may be mounted to cabinet 110 within upper cooking chamber 120. Thus, slide assemblies 172 may be positioned within upper cooking chamber 120, e.g., when upper door 121 is in the closed position. As another example, slide assemblies 172 may be mounted to cabinet 110 outside of upper cooking chamber 120. Thus, slide elements 172 may be positioned such that slide elements 172 are shielded from upper cooking chamber 120 and, e.g., not exposed to heated air within or from upper cooking chamber 120 when upper door 121 is in the closed position.

As may be seen in FIG. 2, cabinet 110 defines an opening 118 for accessing upper cooking chamber 120 of cabinet 110. Upper door 121 is positioned at or adjacent opening 118 of cabinet 110 when upper door 121 is in the closed position. Conversely, upper door 121 is spaced apart from cabinet 110, e.g., opening 118 of cabinet 110, along the transverse direction T when upper door 121 is in the open position. For example, upper door 121 may move along the transverse direction T on slide assemblies 172 such that upper door 121 is spaced apart from opening 118 of cabinet 110 by at least one foot along the transverse direction T when upper door 121 is in the open position.

As discussed above, upper door 121 is pivotable, e.g., on an axis that is parallel to the lateral direction L, between the vertical and peak configurations. For example, upper door 121 may be pivotable by at least thirty degrees, e.g., about an axis that is parallel to the lateral direction L, between the vertical and peak positions. As another example, upper door 121 may be pivotable by at least sixty degrees, e.g., about an axis that is parallel to the lateral direction L, between the vertical and peak positions. As yet another example, upper door 121 may be pivotable by about ninety degrees, e.g., about an axis that is parallel to the lateral direction L, between the vertical and peak positions.

When upper door 121 is in the closed position and the vertical configuration as shown in FIG. 1, upper door 121 seals or closes upper cooking chamber 120. Thus, such position and orientation of upper door 121 may be used when cooking food items within upper cooking chamber 120. If a user wants to check on the food items, the user may pivot upper door 121 to the peak position in order to allow the user to view and observe the food items within upper cooking chamber 120. Thus, when upper door 121 is in the closed position and the peak configuration as shown in FIG. 2, upper door 121 may be positioned and oriented to allow the user to view food items within upper cooking chamber 120 without removing the food items from upper cooking chamber 120. Upper door 121 is also pivotable between the vertical and peak configurations when upper door 121 is in the open position as may be seen in FIGS. 3 and 4.

Range appliance 100 also includes a rack assembly 180 that includes features for supporting food items thereon. Rack assembly 180 is slidably coupled to cabinet 110, e.g., with slide assemblies 172, such that rack assembly 180 moves with upper door 121 along the transverse direction T. Thus, food items on rack assembly 180 may be, e.g., at least partially, removed from upper cooking chamber 120 by shifting door from the closed position to the open position. In particular, with food items cooking within upper cooking chamber 120, a user of range appliance 100 may avoid having to reach into upper cooking chamber 120 in order to grasp or handle the food items located therein by grasping handle 123 of upper door 121 and shifting upper door 121 to the open position such that rack assembly 180 slides out of upper cooking chamber 120. Similarly, if the user wants to check on the food items, the user may move upper door 121 to the open position in order to remove the food items from upper cooking chamber 120 and allow the user to view and observe the food items outside of upper cooking chamber 120. Rack assembly 180 is discussed in greater detail below.

FIG. 5 provides a perspective view of a rack assembly 180. In FIG. 5, rack assembly 180 is shown partially exploded. As may be seen in FIG. 5, rack assembly 180 includes a frame 181, a tray 182 and a rack 183. Frame 181, tray 182 and rack 183 may each have a substantially rectangular shape or form, e.g., in a plane that is perpendicular to the vertical direction. Thus, frame 181, tray 182 and rack 183 may be nested or set together within upper cooking chamber 120.

Frame 181 is mounted to slide assemblies 172 such that frame 181 extends between slide assemblies 172, e.g., along the lateral direction L. In particular, slide rails of first and second slide assemblies 174, 176 may be mounted or fastened to frame 181. Frame 181 may rigidly couple slide assemblies 172 together in order to hinder racking or misalignment of rack assembly 180. Thus, frame 181 may couple slide assemblies 172 together such that slide assemblies 172 extend simultaneously or at a common velocity during adjustment of upper door 121 between the open and closed positions.

Tray 182 is removably mounted to frame 181, and rack 183 is disposed on tray 182. Rack 183 is configured for supporting food items thereon. Tray 182 is positioned below rack 183 and above heating element 160, e.g., along the vertical direction V. Thus, tray 182 may be positioned for catching and collecting food particles and/or liquid spills from food items on rack 183 in order to hinder or prevent such food particles and/or liquid spills from contacting heating element 160. In particular, tray 182 includes a recessed portion 184 and a lip 185 that extends about recessed portion 184 of tray 182. Recessed portion 184 of tray 182 is disposed within frame 181, and lip 185 of tray 182 is positioned on frame 181 when tray 182 is mounted to frame 181. Thus, lip 185 of tray 182 holds or supports recessed portion 184 of tray 182 within frame 181 such that recessed portion 184 of tray 182 is positioned for collecting food particles and/or liquid spills from food items on rack 183. Tray 182 may be construed of or with any suitable material. For example, tray 182 may be constructed with a metal, such as steel, with a suitable coating, such as enamel.

Turning back to FIGS. 1 and 2, rack 183 may be positioned within upper cooking chamber 120 when upper door 121 is in the closed position. Conversely, at least a portion of rack 183 is positioned outside of the upper cooking chamber 120 when upper door 121 is in the open position as shown in FIGS. 3 and 4. As an example, at least fifty percent of rack 183 may be disposed outside of upper cooking chamber 120 when upper door 121 is in the open position. As another example, at least ninety percent of rack 183 may be disposed outside of upper cooking chamber 120 when upper door 121 is in the open position. As yet another example, all of rack 183 may be disposed outside of upper cooking chamber 120 when upper door 121 is in the open position.

FIG. 6 provides a perspective view of a drawer assembly 150 of range appliance 100. FIG. 7 provides a side section view of drawer assembly 150. Drawer assembly 150 includes various components of range appliance 100 associated with upper cooking chamber 120, including upper door 121, slide assemblies 172, rack assembly 180, etc. It should be understood that lower cooking chamber 124 may be constructed in similar manner as upper cooking chamber 120 and range appliance 100 may include similar features and components for lower cooking chamber 124. Thus, lower door 125 may be mounted to slide assemblies such that lower door 125 is movable along the transverse direction T and may also be pivotable about an axis that is parallel the lateral direction L.

As may be seen in FIG. 6, drawer assembly 150 includes a chamber liner 152 that assists with defining upper cooking chamber 120. Chamber liner 152 includes a top wall 154, side walls 156 and a bottom wall 158. Top and bottom walls 154, 158 of chamber liner 152 are spaced apart from each other, e.g., along the vertical direction V. Side walls 156 of chamber liner 152 extend between and connect top and bottom walls 154, 158 of chamber liner 152, e.g., along the vertical direction V. Chamber liner 152 may be constructed of or with any suitable material. For example, chamber liner 152 may be constructed with a metal, such as steel, with a suitable coating, such as enamel. In particular, a single sheet of metal may be folded, bent or otherwise deformed to form top wall 154, side walls 156 and bottom wall 158 of chamber liner 152. As another example, top wall 154, side walls 156 and bottom wall 158 of chamber liner 152 may be formed of or with discrete metal panels.

Each side wall of side walls 156 may include or define embossed supports 157, e.g., that extend along the transverse direction T. Embossed supports 157 may be distributed along the vertical direction V, and each embossment 157 on one of side walls 156 may be aligned with a respective embossment 157 on the other one of side walls 156. A rack (not shown) may be supported on embossed supports 157. For example, the rack may be inserted between adjacent embossed supports 157 one each side wall 156.

As may be seen in FIG. 7, when upper door 121 is positioned in the closed position at cabinet 110, tray 182 is positioned over heating element 160, e.g., along the vertical direction V. In particular, tray 182 may be positioned directly over heating element 160 along the vertical direction V such that tray 182 covers heating element 160 and is disposed between heating element 160 and rack 183 along the vertical direction V when upper door 121 is in the closed position. Such positioning of tray 182 may assist with shielding heating element 160 from food particles and liquid spills. Tray 182 may also assist with uniform heating of food items within upper cooking chamber 120. For example, tray 182 may act as a radiant heat emitter during operation of heating element 160.

FIG. 8 provides a perspective view of certain components of drawer assembly 150. As may be seen in FIG. 8, drawer assembly 150 includes at least one hat bracket 178. Hat bracket 178 is mounted to one of side walls 156 within upper cooking chamber 120. In particular, hat bracket 178 is mounted to one of side walls 156 such that hat bracket 178 is positioned over one of embossed supports 157. One of slide assemblies 172, e.g., second slide assembly 176, is mounted to hat bracket 178. In particular, a slide rail of second slide assembly 176 may be mounted or fastened to hat bracket 178. Hat bracket 178 provides a flat surface for mounting one of slide assemblies 172 in upper cooking chamber 120 over one of embossed supports 157. Thus, hat bracket 178 may extend over one of the embossed supports 157 and be mounted to one of side walls 156 of chamber liner 152.

It should be understood that in alternative exemplary embodiments, range appliance 100 need not include hat bracket 178. For example, when side walls 156 of chamber liner 152 do not include embossed supports 157, slide assemblies 172 may be directly mounted to side walls 156 of chamber liner 152 within upper cooking chamber 120. Similarly, slide assemblies 172 may be mounted to side walls 156 of chamber liner 152 with an adapter plate when side walls 156 of chamber liner 152 do not include embossed supports 157.

Range appliance 100 also includes a hinge assembly 200. Hinge assembly 200 pivotally couples upper door 121 to cabinet 110 and/or at least one of slide assemblies 172 such that upper door 121 is pivotable between the vertical and peak positions. Hinge assembly 200 may be constructed in the same or similar manner to the hinge assembly described in U.S. Patent Publication No. 2015/0354828 of Adelmann et al., which is incorporated by reference in its entirety for all purposes. As discussed in greater detail below, hinge assembly 200 includes features for limiting air flow into upper door 121 from upper cooking chamber 120. Thus, hinge assembly 200 may assist with limiting heating of upper door 121 with air from upper cooking chamber 120, e.g., during a cleaning cycle of range appliance 100.

FIG. 9 provides a partial, elevation view of upper door 121 and hinge assembly 200 of range appliance 100. FIG. 10 is a section view of a hinge arm 210 taken along the 10-10 line of FIG. 9. As may be seen in FIGS. 9 and 10, hinge assembly 200 includes hinge arm 210 that is mounted to upper door 121 and extends through an opening 202 defined by upper door 121, e.g., along the transverse direction T, to one of slide assemblies 172 (FIG. 3). Thus, hinge arm 210 is also mounted to one of slide assemblies 172, e.g., at a distal end portion 218 of hinge arm 210. Hinge arm 210 may be mounted to the one of slide assemblies 172 using any suitable method or mechanism, such as fasteners, welding, etc. Hinge arm 210 may be pivotally mounted to the one of slide assemblies 172 using any suitable method or mechanism, such as fasteners, etc.

Hinge arm 210 has a plurality of non-square or rounded edges 212. Rounded edges 212 of hinge arm 210 may be positioned at or adjacent opening 202 of upper door 121. Thus, hinge arm 210 may engage or interface with upper door 121 and other components or range appliance 100 at rounded edges 212 of hinge arm 210. All edges of hinge arm 210, e.g., in a plane that is perpendicular to the transverse direction T, at or adjacent opening 202 of upper door 121 may be rounded or non-square in certain exemplary embodiments.

Hinge arm 210 may have any suitable number of rounded edges 212, e.g., in a plane that is perpendicular to the transverse direction T. For example, as may be seen in FIG. 10, hinge arm 210 may have a rounded rectangular cross-section, e.g., in a plane that is perpendicular to the transverse direction T. Thus, hinge arm 210 may have four rounded edges 212 in certain exemplary embodiments. In particular, hinge arm 210 may have two top edges 214 and two bottom edges 216, e.g., spaced apart from each other along the vertical direction V, that are all rounded. Hinge arm 210 may be taller along the vertical direction V than hinge arm 210 is wide along the lateral direction L. Thus, a major axis of the rounded rectangular cross-section of hinge arm 210 may be vertically oriented, e.g., parallel to the vertical direction V, as shown in FIG. 10.

Range appliance 100 also includes a gasket 220. Gasket 220 is mounted to upper door 121 at opening 202 of upper door 121. Gasket 220 extends around hinge arm 210, e.g., in a plane that is perpendicular to the transverse direction T. Gasket 220 contacts hinge arm 210 at rounded edges 212 of hinge arm 210. Thus, gasket 220 may extend between upper door 121 and hinge arm 210 within opening 202 such that gasket 220 interfaces or engages with hinge arm 210 at rounded edges 212.

Gasket 220 assists with sealing upper cooking chamber 120 from an interior volume of upper door 121. Thus, e.g., gasket 220 may limit fluid flow between upper cooking chamber 120 and the interior volume of upper door 121. In particular, gasket 220 may block heated air from upper cooking chamber 120 from flowing into upper door 121 and thereby limit heating of an exterior surface of upper door 121 that faces away from upper cooking chamber 120, e.g., particularly during cleaning cycles of range appliance 100 where temperatures within upper cooking chamber 120 may exceed six hundred degrees Fahrenheit.

Gasket 220 may be any suitable type of gasket suitable for use within range appliance 100. For example, gasket 220 may be constructed of or with a stainless steel weave or mesh that is coated with graphite. As another example, gasket 220 may be constructed of or with a stainless steel brush. Thus, e.g., gasket 220 may be constructed to withstand heating to high temperatures, e.g., greater than six hundred degrees Fahrenheit. As shown in FIG. 9, gasket 220 may have a pair of wings 222, e.g., that are mounted to upper door 121 at opposite lateral sides of opening 202. Hinge arm 210 may be positioned between wings 222 of gaskets 220 within opening 202. Hinge arm 210 may slide between wings 222 during pivoting of upper door 121 between the vertical and peak configurations. Wings 222 may be stainless steel weave or stainless steel brush, as described above.

By engaging rounded edges 212, gasket 220 may facilitate sealing of a gap between upper door 121 and hinge arm 210 at opening 202 of upper door 121. In particular, gasket 220 may contact more of hinge arm 210 at rounded edges 212 relative to hinge arms with square edges. Thus, rounded edges 212 facilitate sealing between gasket 220 and hinge arm 210 as upper door 121 shifts between the vertical and peak configurations.
