The present subject matter relates generally to oven range appliances and cooling assemblies for the same.
BACKGROUND OF THE INVENTIONOven range appliances generally include a cabinet that defines a cooking chamber for baking or broiling food items therein as well as a cooktop positioned at a top portion of the cabinet for grilling, boiling or frying food items thereon. To heat the cooking chamber, oven range appliances include heating elements, such as a bake heating element positioned at a bottom portion of the cooking chamber and/or a broil heating element positioned at a top portion of the cooking chamber. During operation of such heating elements, the cabinet and other components of the oven appliance can be heated. In particular, an outer surface of the cabinet and an outer surface of the oven appliance's door can be heated during operation of such heating elements.
The outer surface of the cabinet and/or the outer surface of the oven appliance's door are preferably maintained below a threshold temperature during operation of the oven appliance. Additionally, certain electronics, such as PCBs, and/or electrical components, such as a latch motor, within the oven appliance are preferably maintained below a specified temperature during operation of the oven appliance.
Certain oven appliances include a fan and duct system that draws or pulls air into the oven appliance for cooling oven appliances components during operation of such oven appliances. However, such fan and duct systems can be noisy when the fan is operating. Further, such fan and duct systems can add to the overall cost and complexity of their associated oven appliances.
Accordingly, a cooling assembly for an oven appliance that assists with maintaining a temperature of an outer surface of the oven appliance's door below a threshold temperature would be useful. In particular, a cooling assembly for an oven appliance that assists with maintaining a temperature of an outer surface of the oven appliance's door below a threshold temperature without using of a fan would be useful. Further, a cooling assembly for an oven appliance that assists with maintaining electronics or electronic components of the oven appliance below a threshold temperature would be useful.

Oven range appliance 10 also includes a cooktop portion 44 positioned at top portion 30 of oven range appliance 10. Cooktop portion 44 includes a plurality of heating assemblies 46 positioned below grates 48. Heating assemblies 46 are positioned above cooking chamber 14 of cabinet 12, e.g., along the vertical direction V. Cooking utensils, such as pots, pans, griddles, etc., may be placed on grates 48 and heated with heating assemblies 46 during operation of oven range appliance 10. In
Oven range appliance 10 also includes a cooling assembly 50. Cooling assembly 50 is positioned adjacent top portion 30 of cabinet 12, e.g., between heating assemblies 46 and cooking chamber 14 along the vertical direction V. Cooling assembly 50 is configured for limiting or reducing heat transfer along the vertical direction V during operation of oven range appliance 10. In particular, cooling assembly 50 is configured for directing a flow of air (shown with arrows F) therethrough in order to limit or reduce heat transfer along the vertical direction V during operation of bottom and/or top heating elements 40 and 42 of oven range appliance 10. Cooling assembly 50 is discussed in greater detail below.
Cooling assembly 50 defines at least one inlet 52 and at least one outlet 54. Inlet 52 is positioned at or adjacent front portion 34 of cabinet 12. Inlet 52 of cooling assembly 50 is also positioned adjacent or proximate door 16, e.g., when door 16 is in the closed position. Conversely, outlet 54 of cooling assembly 50 is positioned at or adjacent back portion 35 of cabinet 12. In particular, outlet 54 of cooling assembly 50 is positioned within a cover 58 of oven range appliance 10 at back portion 35 of cabinet 12. Outlet 54 of cooling assembly 50 is positioned above inlet 52 of cooling assembly 50, e.g., along the vertical direction V.
Flow of air F enters cooling assembly 50 at inlet 52 of cooling assembly 50 and flows through cooling assembly 50 to outlet 54 of cooling assembly 50. Flow of air F exits cooling assembly 50 at outlet 54 of cooling assembly 50. Flow of air F can assist with limiting heat transfer along the vertical direction V within cooling assembly 50. For example, a lower surface 70 of cooling assembly 50 can be heated during operation of bottom and/or top heating elements 40 and 42 of oven range appliance 10. Flow of air F can be cool relative to lower surface 70 of cooling assembly 50 such that flow of air F limits or reduces heat transfer between lower surface 70 of cooling assembly 50 and an upper surface 72 of cooling assembly 50 during operation of bottom and/or top heating elements 40 and 42 of oven range appliance 10, e.g., such that upper surface 72 of cooling assembly 50 is cool relative to lower surface 70 of cooling assembly 50. In such a manner, components of oven range appliance 10, such as electronic or electrical components, above cooling assembly 50 can be insulated, e.g., from high temperatures of cooking chamber 14 during operation of oven range appliance 10.
As may be seen in
Oven range appliance 10 also includes features for limiting or reducing heat transfer within door 16, e.g., along the transverse direction T during operation of oven range appliance 10. As may be seen in
Flow of air F through door 16 can assist with limiting or reducing heat transfer along the transverse direction T, e.g., during operation of bottom and/or top heating elements 40 and 42 of oven range appliance 10. As an example, an inner surface 67 of door 16 faces and is positioned adjacent cooking chamber 14 of cabinet 12 when door 16 is in the closed position. Conversely, an outer surface 68 of door 16 is positioned opposite inner surface 67 of door 16 and faces away from cooking chamber 14 of cabinet 12 when door 16 is in the closed position. Inner surface 67 of door 16 can be heated during operation of bottom and/or top heating elements 40 and 42 of oven range appliance 10. Flow of air F can be cool relative to inner surface 67 of door 16 such that flow of air F limits or reduces heat transfer between inner surface 67 of door 16 and outer surface 68 of door 16 during operation of bottom and/or top heating elements 40 and 42 of oven range appliance 10, e.g., such that outer surface 68 of door 16 is cool relative to inner surface 67 of door 16. In such a manner, outer surface 68 of door 16 can be insulated, e.g., such that a temperature of outer surface 68 of door 16 is maintained below a threshold temperature and overheating of outer surface 68 of door 16 is prevented or limited.
Inlet 52 of cooling assembly 50 is positioned adjacent (or at) and faces exit 64 of door 16, e.g., such inlet 52 of cooling assembly 50 is configured for receiving flow of air F from exit 64 of door 16 during operation of oven range appliance 10. In particular, door 16 and cabinet 12 define a gap G therebetween when door 16 is in the closed position. Gap G may be positioned at or adjacent upper portion 65 of door 16 and/or top portion 30 of cabinet 12. Inlet 52 of cooling assembly 50 and exit 64 of door 16 are positioned at or adjacent gap G. Thus, inlet 52 of cooling assembly 50 and exit 64 of door 16 are aligned and spaced apart from each other along the transverse direction T by gap G.
Gasket 20 is positioned at gap G. Gasket 20 extends across gap G between door 16 and cabinet 12, e.g., when door 16 is in the closed position. Inlet 52 of cooling assembly 50 and exit 64 of door 16 are positioned above gasket 20, e.g., along the vertical direction V, when door 16 is in the closed position.
During operation of oven range appliance 10, flow of air F enters channel 62 of door 16 at inlet 60 of door 16 and flows through channel 62 of door 16 to exit 64 of door 16. Within door 16, flow of air F limits or hinders heat transfer along the transverse direction T, e.g., in the manner discussed above. Flow of air F exits channel 62 of door 16 at exit 64 of door 16 and enters gap G. Within gap G, flow of air F can mix with air within gap G. From gap G, flow of air F enters cooling assembly 50 at inlet 52 of cooling assembly 50. Flow of air F passes through cooling assembly 50 and limits or hinders heat transfer along the vertical direction V, e.g., in the manner discussed above.
Cooling assembly 100 includes a main body 110. Main body 110 can be constructed of any suitable material and components. For example, main body 110 may be constructed with a plurality of panels 112 mounted to each other. Panels 112 may be sheet metal panels or any other suitable material. Main body 110 may also be constructed with a molded material.
Main body 110 extends between a top portion 116 and a bottom portion 114, e.g., along the vertical direction V. Thus, top and bottom portions 116 and 114 of main body 110 are spaced apart from each other, e.g., along the vertical direction V. Main body 110 also extends between a first side portion 118 and a second side portion 120, e.g., along the lateral direction L. Thus, first and second side portions 118 and 120 of main body 110 are spaced apart from each other, e.g., along the lateral direction L. Main body 110 further extending between a front portion 122 and a back portion 124, e.g., along the transverse direction T. Thus, front and back portions 122 and 124 of main body 110 are spaced apart from each other, e.g., along the transverse direction T.
Main body 110 defines an inlet 126, a flow passage 134 and a pair of outlets 128. Inlet 126 of main body 110 is configured for receiving flow of air F and directing flow of air F into flow passage 134. Flow passage 134 extends between inlet 126 of main body 110 and outlets 128 of main body 110 such that inlet 126 of main body 110 and outlets 128 of main body 110 are in fluid communication with each other via flow passage 134. Thus, flow passage 134 is configured for directing flow of air F from inlet 126 of main body 110 to outlets 128 of main body 110. Flow of air F can exit cooling assembly 100 at outlets 128 of main body 110.
The position of inlet 126 of main body 110 relative to outlets 128 of main body 110 can assist with urging or drawing flow of air F through flow passage 134. Similarly, the size of inlet 126 of main body 110 relative to outlets 128 of main body 110 can assist with urging or drawing flow of air F through flow passage 134. In such a manner, flow of air F can be urged or drawn through flow passage 134 without requiring fans or other mechanical air handlers.
Inlet 126 of main body 110 is positioned at or adjacent bottom portion 114 and front portion 122 of main body 110. Further, inlet 126 of main body 110 extends along the lateral direction L between about first and second side portions 118 and 120 of main body 110. Outlets 128 of main body 110 are positioned at or adjacent top portion 116 and back portion 124 of main body 110. Thus, inlet 126 of main body 110 is spaced apart from outlets 128 of main body 110 along the vertical direction V and the transverse direction T.
In particular, outlets 128 of main body 110 are spaced apart from inlet 126 of main body 110 along the vertical direction V by a height H (
As discussed above, the size of inlet 126 of main body 110 relative to outlets 128 of main body 110 can assist with urging or drawing flow of air F through flow passage 134. In particular, outlets 128 of main body 110 define a cross-sectional area, e.g., in a plane that is perpendicular to the vertical direction V. Similarly, inlet 126 of main body 110 define a cross-sectional area, e.g., in a plane that is perpendicular to the transverse direction T. In certain exemplary embodiments, the cross-sectional area of outlets 128 of main body 110 is less than the cross-sectional area of inlet 126 of main body 110. For example, the cross-sectional area of outlets 128 of main body 110 may be less than about seventy-five percent of the cross-sectional area of inlet 126 of main body 110.

Cabinet 12 can define passages (not shown) that extend between about door 16 and side inlet 150 of main body 110. Thus, side inlet 150 can capture heated air expelled from door 16 and, e.g., permits such heated air to enter flow passage 134 of main body 110. In particular, side inlets 150 can permit heated air rising between door 116 and cabinet 12 to enter fluid passage 134 of main body 110. Side inlets 150 can assist with fluid flow around cooking chamber 14 of cabinet 12 and thereby facilitate insulation of cooking chamber 14.
