The present subject matter relates generally to oven appliances, and more particularly, to heating assemblies of an oven appliance.
Conventional residential and commercial oven appliances generally include a cabinet that includes a cooking chamber for receipt of food items for cooking. Multiple gas or electric heating elements are positioned within the cabinet for heating the cooking chamber to cook food items located therein. The heating elements can include, for example, a bake heating assembly positioned at a bottom of the cooking chamber and a separate broiler heating assembly positioned at a top of the cooking chamber.
Typically, food or utensils for cooking are placed on wire racks within the cooking chamber and above the bake heating assembly. In some instances, protective or radiant plates are positioned over the bake heating assembly to protect the bake heating assembly or assist in evenly distributing heat across the bottom of the cooking chamber. Oftentimes, the wire racks are at least mounted well above a bake heating assembly to ensure the bake heating assembly is not damaged or a user does not accidentally contact the bake heating assembly. When the bake heating assembly is activated, heat from the bake heating assembly is thus forced to rise through an air gap, and any other intermediate elements, between the bake heating assembly and the wire rack before the utensil on the wire rack can be heated. Heat is within the cooking chamber is relatively diffuse, and the temperature is generally consistent about the item or items on the rack. Moreover, debris, such as crumbs or other small particles, may fall through the wire racks or otherwise collect on a bottom wall of the cooking chamber, such as nearby or below the bake heating element.
Although these conventional configurations are useful for many types of foods, there are certain disadvantages. For instance, certain food items benefit from very high, localized (i.e., non-diffuse) heat. Oftentimes, stone or specialized high-heat pans are used for trapping heat against the bottom of flat-breads or pizza. Such pans may be difficult to preheat or maintain a specific temperature desired by the user. Although placing a pan closer to a heating element may help heat the pan faster or to a higher temperature, the pan may be difficult to secure or stabilize close to the heating element. High heat, in particular, may create difficulties in supporting or mounting any pan adjacent to a heating element. Moreover, none of these conventional designs address issues that arise with crumbs or particles at the bottom of the cooking chamber, which may be difficult to clean or remove.
Accordingly, it would be advantageous to provide an oven appliance capable of safely generating high heat on a specific and secure cooking surface. Additionally or alternatively, it may be useful to provide an assembly for readily collecting debris (e.g., away from a heating element).
Aspects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.

As used herein, the term “or” is generally intended to be inclusive (i.e., “A or B” is intended to mean “A or B or both”). The terms “first,” “second,” and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components. The terms “upstream” and “downstream” refer to the relative flow direction with respect to fluid flow in a fluid pathway. For example, “upstream” refers to the flow direction from which the fluid flows, and “downstream” refers to the flow direction to which the fluid flows. The terms “coupled,” “fixed,” “attached to,” and the like refer to both direct coupling, fixing, or attaching, as well as indirect coupling, fixing, or attaching through one or more intermediate components or features, unless otherwise specified herein.
As disclosed herein, a modular trim assembly may be provided to secure a cooking plate that can be directly cooked upon while covering or hiding a bottom heating assembly within an oven appliance.
Referring now to the drawings,
Although aspects of the present subject matter are described herein in the context of a double oven appliance 100, it should be appreciated that oven appliance 100 is provided by way of example only. Other oven or range appliances having different configurations, different appearances, or different features may also be utilized with the present subject matter as well (e.g., single ovens, electric cooktop ovens, induction cooktops ovens, etc.).
Generally, oven appliance 100 has a cabinet 101 that defines a vertical direction V, a longitudinal direction L and a transverse direction T. The vertical, longitudinal and transverse directions are mutually perpendicular and form an orthogonal direction system. In this regard, as used herein, the terms “cabinet,” “housing,” and the like are generally intended to refer to an outer frame or support structure for appliance 100, e.g., including any suitable number, type, and configuration of support structures formed from any suitable materials, such as a system of elongated support members, a plurality of interconnected panels, or some combination thereof. It should be appreciated that cabinet 101 does not necessarily require an enclosure and may simply include open structure supporting various elements of appliance 100. By contrast, cabinet 101 may enclose some or all portions of an interior of cabinet 101. It should be appreciated that cabinet 101 may have any suitable size, shape, and configuration while remaining within the scope of the present subject matter.
Double oven appliance 100 includes an upper oven 120 and a lower oven 140 positioned below upper oven 120 along the vertical direction V. Upper and lower ovens 120 and 140 include oven or cooking chambers 122 and 142, respectively, configured for the receipt of one or more food items to be cooked. Specifically, cabinet 101 defines a respective opening 123 for each cooking chamber 122 and 142. For instance, an upper opening 123 may be defined (e.g., along the transverse direction T) to access upper cooking chamber 122.
Double oven appliance 100 includes an upper door 124 and a lower door 144 in order to permit selective access to cooking chambers 122 and 142, respectively (e.g., via the corresponding opening). Handles 102 are mounted to upper and lower doors 124 and 144 to assist a user with opening and closing doors 124 and 144 in order to access cooking chambers 122 and 142. As an example, a user can pull on handle 102 mounted to upper door 124 to open or close upper door 124 and access cooking chamber 122. Glass window panes 104 provide for viewing the contents of cooking chambers 122 and 142 when doors 124, 144 are closed and also assist with insulating cooking chambers 122 and 142. Optionally, a seal or gasket (e.g., gasket 114) extends between each door 124, 144 and cabinet 101 (e.g., when the corresponding door 124 or 144 is in the closed position). Such gasket may assist with maintaining heat and cooking fumes within the corresponding cooking chamber 122 or 142 when the door 124 or 144 is in the closed position. Moreover, heating elements, such as electric resistance heating elements, gas burners, microwave elements, etc., are positioned within upper and lower oven 120 and 140.
A control panel 106 of double oven appliance 100 provides selections for user manipulation of the operation of double oven appliance 100. For example, a user can touch control panel 106 to trigger one of user inputs 108. In response to user manipulation of user inputs 108, various components of the double oven appliance 100 can be operated. Control panel 106 may also include a display 112, such as a digital display, operable to display various parameters (e.g., temperature, time, cooking cycle, etc.) of the double oven appliance 100.
Generally, oven appliance 100 may include a controller 110 in operative communication (e.g., operably coupled via a wired or wireless channel) with control panel 106. Control panel 106 of oven appliance 100 may be in communication with controller 110 via, for example, one or more signal lines or shared communication busses, and signals generated in controller 110 operate oven appliance 100 in response to user input via user input devices 108. Input/Output (“I/O”) signals may be routed between controller 110 and various operational components of oven appliance 100 such that operation of oven appliance 100 can be regulated by controller 110.
Controller 110 is a “processing device” or “controller” and may be embodied as described herein. Controller 110 may include a memory and one or more microprocessors, microcontrollers, application-specific integrated circuits (ASICS), CPUs or the like, such as general or special purpose microprocessors operable to execute programming instructions or micro-control code associated with operation of oven appliance 100, and controller 110 is not restricted necessarily to a single element. The memory may represent random access memory such as DRAM, or read only memory such as ROM, electrically erasable, programmable read only memory (EEPROM), or FLASH. In one embodiment, the processor executes programming instructions stored in memory. The memory may be a separate component from the processor or may be included onboard within the processor. Alternatively, controller 110 may be constructed without using a microprocessor (e.g., using a combination of discrete analog or digital logic circuitry; such as switches, amplifiers, integrators, comparators, flip-flops, AND gates, and the like) to perform control functionality instead of relying upon software.
Turning now to
As shown, upper oven includes one or more heating elements to heat upper cooking chamber 122 (e.g., as directed by controller 110 as part of a cooking operation). For instance, a bottom heating element 150 may be mounted at a bottom portion of upper cooking chamber 122 (e.g., above bottom wall 130). Additionally or alternatively, a top heating element 152 may be mounted at a top portion of upper cooking chamber 122 (e.g., below top wall 128). Bottom heating element 150 and top heating element 152 may be used independently or simultaneously to heat upper cooking chamber 122, perform a baking or broil operation, perform a cleaning cycle, etc.
The heating elements 150, 152 may be provided as any suitable heater for generating heat within upper cooking chamber 122. For instance, either heating element may include an electric heating element (e.g., resistance wire elements, radiant heating element, electric tubular heater or CALROD®, halogen heating element, etc.). Additionally or alternatively, either heating element may include a gas burner.
Referring still to
When mounted within cooking chamber 122, cooking plate 154 extends along the transverse direction T between a front end 160 and a rear end 162, along the lateral direction L between a first lateral end 164 and a second lateral end 166, and along the vertical direction V between an upper cooking surface 156 and a lower surface 158. The cooking surface 156, in particular, is disposed between the bottom wall 130 and the top wall 128. Moreover, cooking surface 156 may be proximal to the bottom wall 130 and, thus, distal to the top wall 128. In some embodiments, cooking plate 154 is provided as a solid, nonpermeable member. Thus, food or fluids may be prevented from passing through cooking plate 154 (e.g., along the vertical direction V or perpendicular to cooking surface 156). In certain embodiments, cooking plate 154 includes or is formed from a conductive metal material, such as cast iron, steel, or aluminum (e.g., including alloys thereof). In additional or alternative embodiments, cooking plate 154 includes or is formed from a heat-retaining material, such as clay, stone (e.g., cordierite), ceramic, cast iron, or ceramic-coated carbon steel.
As shown, the cooking plate 154 may be disposed directly above (e.g., in vertical alignment with) the bottom heating element 150. Moreover, cooking plate 154 may define a horizontal footprint that spans across horizontal footprint of bottom heating element 150. In turn, cooking plate 154 may fully cover bottom heating element 150. When mounted within cooking chamber 122, cooking plate 154 may block or otherwise prevent access to bottom heating element 150, such as by a user reaching into the cooking chamber 122. Additionally or alternatively, the bottom heating element 150 may be held out of view such that a user is unable to see the bottom heating element 150. During use, heat generated at bottom heating element 150 may be directed upward to a lower surface 158 of cooking plate 154. As noted, bottom heating element 150 may be vertically aligned with (e.g., directly beneath) the cooking plate 154. The heat generated at bottom heating element 150 may thus be guided primarily or initially to the underside of cooking plate 154.
Turning now generally to
In some embodiments, the modular trim assembly 170 includes a debris trap 172 (e.g., provided as a front, side, or back trim). Generally, debris trap 172 defines a recessed trough 180 into which debris, such as crumbs or other small particles from cooking surface 156 may be collected. Specifically, recessed trough 180 provides a downward-extending void that is disposed below (e.g., at a lower height than) cooking surface 156. For instance, recessed trough 180 may be defined by two or more declined segments 181A, 181B, such as an outward-extending segment 181A and an inward-extending segment 181B. As shown, the outward-extending segment 181A generally descends (e.g., at a constant or variable angle) along a horizontal path outward, away from the cooking plate 154 or cooking chamber 122. The inward-extending segment 181B, by contrast, generally descends (e.g., at a constant or variable angle) along a horizontal path inward, further towards the cooking plate 154 or cooking chamber 122. The declined segments 181A, 181B may be joined together such that recessed trough 180 is vertically closed and prevents the passage of solids or fluids from passing therethrough (e.g., along the vertical direction V). In the illustrated embodiments, the declined segments 181A, 181B are joined together at a base (e.g., lowermost point) of the recessed trough 180.
As shown, recessed trough 180 may be horizontally spaced apart from cooking surface 156. Moreover, at least a portion of the debris trap 172 may be disposed above the cooking surface 156. For instance, the debris trap 172 may extend (e.g., along the transverse direction T) between a defined inner edge that is proximal to the mounted cooking plate 154 to a defined outer edge that is distal to the mounted cooking plate 154 and disposed above the cooking surface 156 (e.g., relative to the vertical direction V). Between the inner edge and the outer edge (e.g., along a horizontal direction, such as the transverse direction T), the recessed trough 180 may be uncovered or accessible, even while cooking plate 154 is mounted within cooking chamber 122. Advantageously, debris or particles on cooking surface 156 may be brushed or raked from (e.g., directly from) cooking surface 156 to recessed trough 180 without falling to bottom wall 130.
In the illustrated embodiments, debris trap 172 is mounted (e.g., removably or fixedly mounted) to cabinet 101 (e.g., at front plate 136). As shown, debris trap 172 may be provided as a front trim. Debris trap 172 may, in turn, be a mounted adjacent to the front portion of cooking chamber 122. Recessed trough 180 may be disposed between opening 123 and at least a portion of the cooking surface 156 along the transverse direction T. As shown, debris trap 172 may extend laterally (i.e., along the lateral direction L) along the opening 123. At least a portion of the lateral width of opening 123 may thus be spanned by debris trap 172. Nonetheless, debris trap 172 may be disposed, at least in part, below opening 123 such that opening 123 is not blocked or otherwise reduced in usable height by debris trap 172. The debris trap 172 may extend along the transverse direction T from the front plate 136 to the cooking plate 154. Additionally or alternatively, debris trap 172 may extend rearward (e.g., generally along the transverse direction T) from opening 123 or toward back wall 126. Optionally, debris trap 172 may be mounted or secured to front plate 136, such as by one or more suitable fasteners, welds, or adhesives.
Turning especially to
As shown, cooking plate 154 may rest on top of debris trap 172. Specifically, the lower surface 158 may be supported on interior flange 174. In turn, interior flange 174 may limit downward vertical movement of cooking plate 154. The vertical retainer tab(s) 178 may be disposed against a peripheral edge 157 of cooking plate 154. For instance, vertical retainer tabs 178 may be disposed in front of and against the front end 160 of cooking plate 154, thereby restricting forward transverse movement of cooking plate 154.
Turning especially to
In some embodiments, rear trim 182 includes a lower back flange 184 to extend beneath the cooking plate 154. For instance, lower back flange 184 may extend forward from back wall 126 along the transverse direction T. As shown, lower back flange 184 may extend from a secured back base 186. Secured back base 186 may, as an example, contact or engage a portion of back wall 126 for support thereon. When mounted within cooking chamber 122, lower back flange 184, in particular, may be disposed below (e.g., at a lower vertical height than opening 123). In some embodiments, a vertical back ridge 188 extends upward from lower back flange 184. As shown, vertical back ridge 188 may extend between or connect lower back flange 184 and secured back base 186. Thus, lower back flange 184 may be transversely and vertically offset from secured back base 186. In optional embodiments, rear trim 182 defines one or more one or more transverse channels 190 therethrough. For instance, between the secured back base 186 and the lower back flange 184, at least one transverse channel 190 may be defined through rear trim 182 along the transverse direction T. Optionally, a pair of discrete transverse channels 190 (i.e., a first transverse channel 190 and a second transverse channel 190) may be defined. Specifically, the transverse channels 190 may be spaced apart from each other along the lateral direction L. In some such embodiments, vertical back ridge 188 is disposed between the pair of transverse channels 190.
Generally, rear trim 182 may be spaced apart (e.g., rearward) from opening 123 or a front trim (e.g., debris trap 172). When mounted within cooking chamber 122, cooking plate 154 may rest on top of rear trim 182. Specifically, the lower surface 158 may be supported on lower back flange 184. In turn, lower back flange 184 may limit downward vertical movement of cooking plate 154. Vertical back ridge 188 may be disposed behind and against the rear end 162 of cooking plate 154, thereby restricting rearward transverse movement of cooking plate 154.
Turning especially to
As shown, side trim 192 may extend laterally (i.e., along the lateral direction L) along the corresponding wall (e.g., first side wall 132). At least a portion of the transverse depth of the corresponding side wall 132 may thus be spanned by side trim 192. When assembled, side trim 192 may be disposed, at least in part, below opening 123. Additionally or alternatively, side trim 192 may extend inward (e.g., generally along the lateral direction L) from the corresponding side wall 132 or toward the opposite side wall 132. Optionally, side trim 192 may be mounted or secured to the corresponding back wall 126 (e.g., a transverse ridge thereon), such as by one or more suitable fasteners, welds, or adhesives. Additionally or alternatively, side trim 192 may be held relative to the back wall 126 (e.g., vertically or along the vertical direction V) via on or more indirect features. For instance, one or more side trim 192 may be held within or vertically constrained by a corresponding transverse channel 190 (e.g., defined by rear trim 182—
In some embodiments, side trim 192 may include an upper side flange 194 to extend on (e.g., over or on top of) the cooking plate 154. For instance, upper side flange 194 may extend inward from the corresponding side wall 132 along the lateral direction L. As shown, upper side flange 194 may extend from one or more secured side bases 196 (e.g., in front of or behind upper side flange 194). A secured side base 196 may, as an example, contact or engage a portion of the corresponding side wall 132 for support thereon (e.g., a ridge formed on wall 132).
As shown, side trims 192 may extend between debris trap 172 and rear trim 182. Optionally, each side trim 192 may extend through a corresponding transverse channel 190. For instance, first side trim 192 may extend through a first transverse channel 190 while second side trim 192 extends through a second transverse channel 190. Thus, the side trims 192 may be held below at least a portion of rear trim 182. When mounted within cooking chamber 122, the side trims 192 may rest on cooking plate 154 (e.g., on cooking surface 156). Specifically, each upper side flange 194 may be supported on cooking surface 156. In turn, upper side flange 194 may limit upward vertical movement of cooking plate 154.
Advantageously, appliances or assemblies in accordance with the present disclosure may provide a secure cooking surface within a cooking chamber that is capable of withstanding high-heat operations (e.g., while hiding or protecting a bottom heating element within the oven appliance).
